[0004] By running each fastening bolt 2 through the each
corresponding fastening bores 23 of pump head cover 20 and each
corresponding fastening bore 63 in the pump head body 60, then
putting a nut 3 onto each fastening bolt 2 to securely screw the
pump head cover 20 and pump head body 60 with the motor upper
chassis 30 via each corresponding fastening bore 33 in the motor
upper chassis 30 so that the whole assembly of the
five-compressing-chamber diaphragm pump is finished (as shown in
FIGS. 1 and 11).
[0005] Please refer to FIGS. 12 and 13, which are illustrative
figures for the operation of "conventional five-compressing-chamber
diaphragm pump".
[0006] Firstly, when the motor 10 is powered on, the wobble plate
40 is driven to rotate by the motor output shaft 11 so that five
tubular eccentric roundels 52 on the eccentric roundel mount 50
orderly move in up-and-down reciprocal stroke constantly;
[0007] Secondly, meanwhile, five pumping pistons 80 and five piston
acting zones 74 in the diaphragm membrane 70 are orderly driven by
the up-and-down reciprocal stroke of five tubular eccentric
roundels 52 to move in up-and-down displacement;
[0008] Thirdly, when the tubular eccentric roundel 52 moves in
"down stroke" with pumping piston 80 and piston acting zone 74 in
down displacement, the piston disk 98 in the piston valvular
assembly 90 is pushed into "open" status so that the tap water W
can flow into the preliminary-compressing chamber 26 orderly via
water inlet orifice 21 in the pump head cover 20 and inlet ports 97
in the piston valvular assembly 90 (as shown in FIG. 12 and
arrowhead indication W in enlarged view of association);
[0009] Fourthly, when the tubular eccentric roundel 52 moves in "up
stroke" with pumping piston 80 and piston acting zone 74 in up
displacement, the piston disk 98 in the piston valvular assembly 90
is pulled into "close" status to compress the tap water W in the
preliminary-compressing chamber 26 to increase the water pressure
therein up to range of 100 psi-150 psi and become into pressurized
water Wp with result that the plastic anti-backflow valve 94 in the
piston valvular assembly 90 is pushed to "open" status;
[0010] Fifthly, when the plastic anti-backflow valve 94 in the
piston valvular assembly 90 is pushed to "open" status, the
pressurized water Wp in the preliminary-compressing chamber 26 is
directed into high-compressing chamber 27 via group of outlet ports
95 for the corresponding sector in central outlet mount 92, then
expelled out of the water outlet orifice 22 in the pump head cover
20 (as shown in FIG. 13 and arrowhead indication Wp in enlarged
view of association); and
[0011] Finally, with orderly iterative action for each group of
outlet ports 95 for five sectors in central outlet mount 92, the
pressurized water Wp is constantly discharged out of the
conventional five-compressing-chamber diaphragm pump for being
further RO-filtered by the RO-cartridge so that the final filtered
pressurized water Wp can be used in the RO (Reverse Osmosis)
purifier or RO water purification system, which is popularly
installed on the water supplying apparatus in either the settled
home, recreational vehicle or mobile home.
[0012] Referring to FIGS. 14 and 15, a primary serious drawback has
long-lasting existed in the foregoing conventional
five-compressing-chamber diaphragm pump is described as below. As
described previously, when the motor 10 is powered on, the wobble
plate 40 is driven to rotate by the motor output shaft 11 so that
five tubular eccentric roundels 52 on the eccentric roundel mount
50 orderly move in up-and-down reciprocal stroke constantly,
meanwhile five pumping pistons 80 and five piston acting zones 74
in the diaphragm membrane 70 are orderly driven by the up-and-down
reciprocal stroke of five tubular eccentric roundels 52 to move in
up-and-down displacement so that equivalently a reiterative acting
force F constantly acting on the five piston acting zones 74 with a
length of moment arm L1 obtained from the outer raised brim 71 to
the peripheral of the annular positioning protrusion 76 (as shown
in FIG. 15). Thereby, a resultant torque is created by the acting
force F multiplying the length of moment arm L1 as shown by the
formula "torque=acting force F.times.length of moment arm L1"
namely. However, the resultant torque causes the whole conventional
five-compressing-chamber diaphragm pump to vibrate directly. With
high rotational speed of the motor output shaft 11 in the motor 10
up to range of 800-1200 rpm, the vibrating strength caused by
alternately acting of five tubular eccentric roundels 52 can reach
unacceptable condition persistently.
[0013] In view of the all drawbacks aforesaid in the conventional
five-compressing-chamber diaphragm pump, as shown in FIG. 16, a
cushion base 100 with a pair of wing plates 101 is always bolstered
as supporting supplementary such that each wing plate 101 is
further sleeved by a rubber shock absorber 102 for vibration
suppressing enhancement. Upon installation the conventional
five-compressing-chamber diaphragm pump in the water supplying
apparatus in the settled home or mobile home, the cushion base 100
is firmly screwed onto the housing C of the reverse osmosis
purification unit by means of suitable fastening screws 103 and
corresponding nuts 104. However, the practical vibration
suppressing efficiency of using foregoing cushion base 100 with
wing plates 101 and rubber shock absorber 102 only affects to the
primary vibrating drawback aforesaid and in limited degree because
the overall "resonant shakes" aforesaid will incur the vibration of
the housing C for the reverse osmosis purification unit to become
stronger with harassing noise. Other than the primary vibrating
drawback aforesaid, the water pipe P connected on the water outlet
orifice 22 of the pump head cover 20 will synchronously "shake" in
resonance with the "vibration" aforesaid (as hypothetic line P for
illustrative view a of association shown in FIG. 16). Thereby, the
synchronous "shake" of the water pipe P will further incur other
rest parts of the "conventional compressing diaphragm pump" to
simultaneously "shake" also. Therefore, after having served for a
certain period, the "water leakage" of the "conventional
compressing diaphragm pump" will happen due to gradually loosed
connection between water pipe P and water outlet orifice 22 as well
as gradually loosed fitness among other rest parts incurred by the
"shake" effects. For the issues of overall "resonant shakes" and
the "water leakage" for the conventional five-compressing-chamber
diaphragm pump aforesaid are incurred by the foregoing primary
vibrating drawback. Therefore, how to substantially reduce all the
drawbacks associated with the operating vibration for the
five-compressing-chamber diaphragm pump becomes an urgent and
critical issue.
[0014] Besides, as described previously, when the motor 10 is
powered on, the wobble plate 40 is driven to rotate by the motor
output shaft 11 so that five tubular eccentric roundels 52 on the
eccentric roundel mount 50 orderly move in up-and-down reciprocal
stroke constantly, and five piston acting zones 74 in the diaphragm
membrane 70 are orderly driven by the up-and-down reciprocal stroke
of five tubular eccentric roundels 52 to move in up-and-down
displacement so that equivalently a reiterative acting force F
constantly acting on the bottom side of each said piston acting
zone 74. Meanwhile a plurality of rebounding force Fs is created to
react the acting force F exerting on the bottom side of diaphragm
membrane 70 with different components distributed over entire
bottom area of each corresponding piston acting zone 74 in the
diaphragm membrane 70 (as shown in FIG. 18) so that a "squeezing
phenomenon" happens on the partial portion of the diaphragm
membrane 70, which is incurred by the rebounding force Fs. Among
all distributed components of the rebounding force Fs, the
component force happened at the contacting bottom position P of the
diaphragm membrane 70 with the rounded shoulder 57 of the
horizontal top face 53 in the tubular eccentric roundel 52 is
maximum so that the "squeezing phenomenon" happened here is also
maximum (as shown in FIG. 18). With rotational speed for the motor
output shaft 11 of the motor 10 reaching a range of 800-1200 rpm,
each bottom position P at the piston acting zone 74 of the
diaphragm membrane 70 is suffered from the "squeezing phenomenon"
in a frequency of five times per second. Under such circumstance,
the bottom position P of the diaphragm membrane 70 is always the
first broken place for entire conventional five-compressing-chamber
diaphragm pump, which is the essential cause for not only
shortening the service lifespan but also terminating normal
function of the conventional five-compressing-chamber diaphragm
pump. Therefore, how to substantially reduce all the drawbacks
associated with the "squeezing phenomenon" caused by the
reiterative acting force F constantly acting on the bottom side of
each said piston acting zone 74 of the diaphragm membrane 70, which
is incurred by the tubular eccentric roundel 52, for the
conventional five-compressing-chamber diaphragm pump also becomes
an urgent and critical issue.
[0015] Referring to FIGS. 19 and 21, they are illustrative figures
for the structure and operation of conventional
five-compressing-chamber diaphragm pump with another piston
valvular assembly 900. The piston valvular assembly 900 includes a
downward outlet raised brim 901 to insert between the outer raised
brim 71 and inner raised brim 72 in the diaphragm membrane 70, a
central round outlet mount 902, five equivalent sector zones evenly
distributed in the outlet mount 902 such that each of sectors
composed of a zone positioning bore 903, a T-shaped zone
anti-backflow valve 904 with a zone positioning shank as well as a
group of multiple evenly circum-located outlet ports 905 around
each corresponding zone positioning bore 903, and five circumjacent
inlet mounts 906 such that each of which includes a group of
multiple evenly circum-located inlet ports 907 and a inverted
central piston disk 908 respectively so that each piston disk 908
serves as a valve for each corresponding group of multiple inlet
ports 907 (as shown in FIG. 19), wherein each zone positioning
shank of the zone anti-backflow valve 904 mates with the zone
positioning bore 903 of the central outlet mount 902 such that each
group of multiple outlet ports 905 of each sector zone in the
central round outlet mount 902 are communicable with each
corresponding inlet mount 906, and a hermetical
preliminary-compressing chamber 26 is formed between each inlet
mount 906 and each corresponding piston acting zone 74 in the
diaphragm membrane 70 upon the downward outlet raised brim 901
having inserted between the outer raised brim 71 and inner raised
brim 72 in the diaphragm membrane 70 such that one end of each
preliminary-compressing chamber 26 is communicable with each
corresponding group of multiple inlet ports 907 (as enlarged view
shown in FIG. 21 of association).
[0016] By running each fastening bolt 2 through the each
corresponding fastening bores 23 of pump head cover 20 and each
corresponding fastening bore 63 in the pump head body 60, then
putting a nut 3 onto each fastening bolt 2 to securely screw the
pump head cover 20 and pump head body 60 with the motor upper
chassis 30 via each corresponding fastening bore 33 in the motor
upper chassis 30 so that the whole assembly of the
five-compressing-chamber diaphragm pump is finished (as shown in
FIGS. 1 and 21).
[0017] Please refer to FIG. 21.
[0018] Firstly, when the motor 10 is powered on, the wobble plate
40 is driven to rotate by the motor output shaft 11 so that five
eccentric roundels 52 on the eccentric roundel mount 50 orderly
move in up-and-down reciprocal stroke constantly;
[0019] Secondly, meanwhile, five pumping pistons 80 and five piston
acting zones 74 in the diaphragm membrane 70 are orderly driven by
the up-and-down reciprocal stroke of five eccentric roundels 52 to
move in up-and-down displacement;
[0020] Thirdly, when the eccentric roundel 52 moves in "down
stroke" with pumping piston 80 and piston acting zone 74 in "down
displacement", the piston disk 908 of corresponding inlet mount 906
in the piston valvular assembly 900 is pushed into "open" status so
that the tap water W can flow into the preliminary-compressing
chamber 26 orderly via water inlet orifice 21 in the pump head
cover 20 and the group inlet ports 907 of corresponding inlet mount
906 in the piston valvular assembly 90 (as arrowhead indication W
shown in FIG. 21);
[0021] Fourthly, when the eccentric roundel 52 moves in "up stroke"
with pumping piston 80 and piston acting zone 74 in "up
displacement", the piston disk 908 in the piston valvular assembly
90 is pulled into "close" status to compress the tap water W in the
preliminary-compressing chamber 26 to increase the water pressure
therein up to range of 100 psi-150 psi and become into pressurized
water Wp with result that the zone anti-backflow valve 904 in the
piston valvular assembly 900 is pushed to "open" status;
[0022] Fifthly, when the zone anti-backflow valve 904 in the piston
valvular assembly 90 is pushed to "open" status, the pressurized
water Wp in the preliminary-compressing chamber 26 is directed into
high-compressing chamber 27 via group of outlet ports 905 for the
corresponding sector in central outlet mount 902, then expelled out
of the water outlet orifice 22 in the pump head cover 20 (as
arrowhead indication Wp shown in FIG. 21); and
[0023] Finally, with orderly iterative action for each group of
outlet ports 95 for five sectors in central outlet mount 902, the
pressurized water Wp is constantly discharged out of the
conventional five-compressing-chamber diaphragm pump for being
further RO-filtered by the RO-cartridge so that the final filtered
pressurized water Wp can be used in the commercial reverse osmosis
water purification system of large sale, which is popularly
installed on the water supplying apparatus in either the settled
home, recreational vehicle or mobile home.
[0024] The foregoing issues of overall "resonant shakes" and the
"water leakage" for the conventional five-compressing-chamber
diaphragm pump incurred by the foregoing primary vibrating drawback
are also happened in the piston valvular assembly 900. Therefore,
how to substantially reduce all the drawbacks associated with the
operating vibration for the five-compressing-chamber diaphragm pump
becomes an urgent and critical issue indeed.
SUMMARY OF THE INVENTION
[0025] The primary object of the present invention is to provide a
five-compressing-chamber diaphragm pump with multiple effects,
which has innovative mating means for a pump head body and a
diaphragm membrane, where the pump head body includes five
operating holes and a basic curved dent circum-disposed around the
upper side of each operating hole while the diaphragm membrane
includes five equivalent piston acting zones each of which with a
acting zone hole, an annular positioning protrusion for each acting
zone hole formed, and a basic curved protrusion circum-disposed
around each concentric annular positioning protrusion in
corresponding position with each mating basic curved dent in the
pump head body so that five basic curved protrusions completely
insert into corresponding five basic curved dents with a short
length of moment arm in generating less torque, which is obtained
by length of moment arm multiplying a constant acting force and
primarily causes adverse vibration. With less torque, the vibration
strength of the five-compressing-chamber diaphragm pump is
substantially reduced.
[0026] Another object of the present invention is to provide a
five-compressing-chamber diaphragm pump with multiple effects,
which has innovative mating means for a pump head body and a
diaphragm membrane, where the pump head body has five basic curved
dents and the diaphragm membrane has five basic curved protrusions
such that five basic curved protrusions completely insert into
corresponding five basic curved dents with a short length of moment
arm in generating less torque, which is obtained by length of
moment arm multiplying a constant acting force and primarily causes
adverse vibration. With less torque, the vibration strength of the
compressing diaphragm pump is substantially reduced. Having the
present invention installed on the housing of the reverse osmosis
purification unit on the water supplying apparatus in either the
settled home or mobile home pillowed by a conventional cushion base
with rubber shock absorber, the harassing noise of the "resonant
shakes" incurred in the five-compressing-chamber diaphragm pump can
be completely eliminated.
[0027] The further object of the present invention is to provide a
five-compressing-chamber diaphragm pump with multiple effects,
which includes a cylindrical eccentric roundel disposed in an
eccentric roundel mount. The cylindrical eccentric roundel
basically comprises an annular positioning dent, a vertical flank
and a sloped top ring created from the annular positioning dent to
the vertical flank. By means of the sloped top ring, the oblique
pull and squeezing phenomena of high frequency incurred in a
conventional tubular eccentric roundel are completely eliminated
because the sloped top ring flatly attaches the bottom area of
corresponding piston acting zone for a diaphragm membrane. Thus,
not only the durability of the diaphragm membrane for sustaining
the pumping action of high frequency from the cylindrical eccentric
roundels is mainly enhanced. But also the service lifespan of the
five-compressing-chamber diaphragm pump is exceedingly
prolonged.
[0028] The other object of the present invention is to provide a
five-compressing-chamber diaphragm pump with multiple effects,
which includes a cylindrical eccentric roundel disposed in an
eccentric roundel mount. The cylindrical eccentric roundel
basically comprises an annular positioning dent, a vertical flank
and a sloped top ring created from the annular positioning dent to
the vertical flank. By means of the sloped top ring, all
distributed components of the rebounding force for the cylindrical
eccentric roundels reacting to the an acting force caused by the
pumping action are substantially reduced because the sloped top
ring flatly attaches the bottom area of corresponding piston acting
zone for a diaphragm membrane.
[0029] Thus, some benefits are obtained as below.
[0030] 1. The durability of the diaphragm membrane for sustaining
the pumping action of high frequency from the cylindrical eccentric
roundels is mainly enhanced.
[0031] 2. The power consumption of the five-compressing-chamber
diaphragm pump is tremendously diminished due to less current being
wasted in the "squeezing phenomena" of high frequency.
[0032] 3. The working temperature of the five-compressing-chamber
diaphragm pump is tremendously subdued due to less power
consumption being used.
[0033] 4. The annoying noise of the bearing incurred by the aged
lubricant in the five-compressing-chamber diaphragm pump, which is
expeditiously accelerated by the high working temperature, is
mostly eliminated.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0163] Please refer to FIGS. 22 through 31, which are illustrative
figures of "five-compressing-chamber diaphragm pump with multiple
effects" for the first exemplary embodiment in the present
invention.
[0164] A basic curved dent 65 is circum-disposed around the upper
side of each operating hole 61 in the pump head body 60 (as shown
in FIGS. 23 to 25) while a basic curved protrusion 77 is
circum-disposed around each concentric annular positioning
protrusion 76 (as shown in FIGS. 27 and 28) at the bottom side of
the diaphragm membrane 70 in corresponding position with each
mating basic curved dent 65 in the pump head body 60 so that each
basic curved protrusions 77 at the bottom side of the diaphragm
membrane 70 completely inserts into each corresponding basic curved
dent 65 at the upper side of the pump head body 60 upon assembly of
the pump head body 60 and the diaphragm membrane 70 (as shown in
FIG. 31), as well as a short length of moment arm L2 from the basic
curved protrusions 77 to the peripheral of the annular positioning
protrusion 76 in the diaphragm membrane 70 is obtained in the
operation of the present invention (as shown in FIG. 31 and
enlarged view of association).
[0165] Moreover, a cylindrical eccentric roundel 52 in an eccentric
roundel mount 50 basically comprises a sloped top ring 58 created
from the annular positioning dent 55 to the vertical flank 56 (as
shown in FIGS. 29 and 30) to replace the conventional rounded
shoulder 57 in each tubular eccentric roundel 52 of the eccentric
roundel mount 50 (as shown in FIGS. 3 and 4).
[0166] Please refer to FIGS. 32, 33, 15 and 16, which are
illustrative figures for the operation of "five-compressing-chamber
diaphragm pump with multiple effects" for the first exemplary
embodiment in the present invention.
[0167] Comparing to the operation of conventional
five-compressing-chamber diaphragm pump, a length of moment arm L1
from the outer raised brim 71 to the peripheral of the annular
positioning protruding block 76 in the diaphragm membrane 70 is
obtained (as shown in FIGS. 15 and 33), a length of moment arm L2
from the basic curved protrusions 77 to the peripheral of the
annular positioning protruding block 76 in the diaphragm membrane
70 is obtained in the operation of the present invention (as shown
in FIG. 33).
[0168] By illustration of foregoing comparative result, it
apparently shows that the length of moment arm L2 is shorter than
the length of moment arm L1.
[0169] While the resultant torque is calculated by same acting
force F multiplying the length of moment arm, the resultant torque
of the present invention is smaller than that of the conventional
five-compressing-chamber diaphragm pump since the length of moment
arm L2 is shorter than the length of moment arm L1.
[0170] With the smaller resultant torque of the present invention,
the vibration strength related is substantially reduced.
[0171] Through practical pilot test for the sample of the present
invention, the result shows that the vibration strength related is
only one tenth (10%) of vibration strength in the conventional
five-compressing-chamber diaphragm pump.
[0172] If the present invention is installed on the housing C of
the reverse osmosis purification unit pillowed by a conventional
cushion base 100 with a rubber shock absorber 102 (as shown in FIG.
16), the harassing noise of the "resonant shakes" incurred in the
conventional five-compressing-chamber diaphragm pump can be
completely eliminated.
[0173] Please refer to FIGS. 34 through 36, which are illustrative
figures for the operation of the "five-compressing-chamber
diaphragm pump with multiple effects" in the first exemplary
embodiment of the present invention.
[0174] Firstly, when the motor 10 is powered on, the wobble plate
40 is driven to rotate by the motor output shaft 11 so that five
cylindrical eccentric roundels 52 on the eccentric roundel mount 50
orderly move in up-and-down reciprocal stroke constantly;
[0175] Secondly, five piston acting zones 74 in the diaphragm
membrane 70 are orderly driven by the up-and-down reciprocal stroke
of five cylindrical eccentric roundels 52 to move in up-and-down
displacement;
[0176] Thirdly, when the conventional tubular eccentric roundel or
cylindrical eccentric roundel 52 of the present invention moves in
"up stroke" with piston acting zone 74 in up displacement, an
acting force F will obliquely pull the partial portion between
corresponding annular positioning protrusion 76 and outer raised
brim 71 of the diaphragm membrane 70;
[0177] Please refer to FIGS. 18 and 35. By comparing to the
operations between the conventional tubular eccentric roundels 52
and the cylindrical eccentric roundels 52 of the present invention,
at least two differences are obtained as below.
[0178] In the case of conventional tubular eccentric roundel 52,
among all distributed components of the rebounding force Fs, the
component force happened at the contacting bottom position P of the
diaphragm membrane 70 with the rounded shoulder 57 of the
horizontal top face 53 in the tubular eccentric roundel 52 is
maximum so that the "squeezing phenomenon" happened here is also
maximum (as shown in FIG. 18). With such nonlinear distribution of
the "squeezing phenomena", the obliquely pulling action becomes
severe. Whereas, in the case of cylindrical eccentric roundels 52,
all distributed components of the rebounding force Fs seem rather
linear because the sloped top ring 58 therein flatly attaches the
bottom area of the piston acting zone 74 for the diaphragm membrane
70 so that the obliquely pulling action almost eliminated due to no
"squeezing phenomenon" (as shown in FIGS. 34 and 35).
[0179] Moreover, under the same acting force F, the rebounding
force Fs is inversely proportional to the contact area so that all
distributed components of the rebounding force Fs for the
cylindrical eccentric roundels 52 of the present invention (as
shown in FIG. 35) are substantially less than all distributed
components of the rebounding force Fs for the conventional tubular
eccentric roundel 52 (as shown in FIG. 18).
[0180] From above comparison, two advantages are inherited by means
of the sloped top ring 58 created from the annular positioning dent
55 to the vertical flank 56 in the eccentric roundel mount 50.
First, the susceptible breakage of the diaphragm membrane 70 caused
by the "squeezing phenomena" of high frequency, which is incurred
by the rounded shoulder 57 of the horizontal top face 53 in the
tubular eccentric roundel 52, is completely eliminated (as
hypothetically dotted line shown in FIG. 36). Second, the
rebounding force Fs of the diaphragm membrane 70 caused by the
acting force F, which is incurred by the orderly up-and-down
displacement of five piston acting zones 74 in the diaphragm
membrane 70 driven by the up-and-down reciprocal stroke of five
tubular eccentric roundels or cylindrical eccentric roundels 52, is
tremendously reduced.
[0181] Therefore, from above inherited advantages, some benefits
are obtained as below.
[0182] 1. The durability of the diaphragm membrane 70 for
sustaining the pumping action of high frequency from the
cylindrical eccentric roundels 52 is mainly enhanced.
[0183] 2. The power consumption of the five-compressing-chamber
diaphragm pump is tremendously diminished due to less current being
wasted in the "squeezing phenomena" of high frequency.
[0184] 3. The working temperature of the five-compressing-chamber
diaphragm pump is tremendously subdued due to less power
consumption being used.
[0185] 4. The annoying noise of the bearing incurred by the aged
lubricant in the five-compressing-chamber diaphragm pump, which is
expeditiously accelerated by the high working temperature, is
mostly eliminated.
[0186] Through practical pilot test for the sample of the present
invention, the testing results are shown as below.
[0187] A. The service lifespan of the diaphragm membrane 70 is
exceedingly extended over twice.
[0188] B. The diminished electric current is over 1 ampere.
[0189] C. The subdued working temperature is over 15 degree of
Celsius.
[0190] D. The smoothness of the bearing is better improved.
[0191] As shown in FIGS. 37 and 38, in the first exemplary
embodiment, each basic curved dent 65 of the pump head body 60 can
be adapted into a basic curved bore 64.
[0192] As shown in FIGS. 39 and 40, in the first exemplary
embodiment, each basic curved dent 65 in the pump head body 60 (as
shown in FIGS. 23 and 25) and each corresponding basic curved
protrusion 77 in the diaphragm membrane 70 (as shown in FIGS. 27
and 28) can be exchanged into a basic curved protrusion 651 in the
pump head body 60 (as shown in FIG. 39) and a corresponding basic
curved dent 771 in the diaphragm membrane 70 (as shown in FIG. 39)
without affecting their mating condition.
[0193] Thereby, each basic curved protrusion 651 at the upper side
of the pump head body 60 completely inserts into each corresponding
basic curved dent 771 at the bottom side of the diaphragm membrane
70 upon assembly of the pump head body 60 and the diaphragm
membrane 70 (as shown in FIG. 40).
[0194] Moreover, a short length of moment arm L3 from the basic
curved dent 771 to the peripheral of the annular positioning
protrusion 76 in the diaphragm membrane 70 is also obtained in the
operation of the present invention (as shown in FIG. 40 and
enlarged view of association) so that the newly devised
contrivances of pump head body 60 and diaphragm membrane 70 have
significant effect in reducing vibration as well.
[0195] Please refer to FIGS. 41 through 47, which are illustrative
figures of "five-compressing-chamber diaphragm pump with multiple

[0223] Please refer to FIGS. 116 through 118, which are
illustrative figures of "five-compressing-chamber diaphragm pump
with multiple effects" in a modified mode of for the ninth
exemplary embodiment of the present invention. The cylindrical
eccentric roundel 52 is modified into an inverted conical frustum
eccentric roundel 502 in an eccentric roundel mount 500, wherein
the conical frustum eccentric roundel 502 basically comprises an
integral inverted conical frustum flank 506 and a sloped top ring
508 such that the outer diameter of the conical frustum eccentric
roundel 502 is enlarged but still smaller than the inner diameter
of the operating hole 61 in the pump head body 60, as well as the
sloped top ring 508 is created from an annular positioning dent 505
to the inverted conical frustum flank 506.
[0224] Please refer to FIGS. 119 through 121, which are
illustrative figures for the operation in the modified mode of the
"five-compressing-chamber diaphragm pump with multiple effects" in
a modified mode of for the ninth exemplary embodiment of the
present invention.
[0225] Firstly, when the motor 10 is powered on, the wobble plate
40 is driven to rotate by the motor output shaft 11 so that five
conical frustum eccentric roundel 502 on the eccentric roundel
mount 500 orderly move in up-and-down reciprocal stroke
constantly;
[0226] Secondly, five piston acting zones 74 in the diaphragm
membrane 70 are orderly driven by the up-and-down reciprocal stroke
of five conical frustum eccentric roundel 502 to move in
up-and-down displacement;
[0227] Thirdly, when the conical frustum eccentric roundel 502 in
the present invention moves in "up stroke" with piston acting zone
74 in up displacement, an acting force F will obliquely pull the
partial portion between corresponding annular positioning
protrusion 76 and outer raised brim 71 of the diaphragm membrane
70; and
[0228] Finally, by means of the sloped top ring 508 in the
eccentric roundel mount 500, not only the susceptible breakage of
the diaphragm membrane 70 caused by the "squeezing phenomena" of
high frequency, which is incurred by the rounded shoulder 57 in the
conventional tubular eccentric roundel 502 (as hypothetical dotted
line shown in FIG. 121), is completely eliminated but also the
rebounding force Fs of the diaphragm membrane 70 caused by the
acting force F is tremendously reduced. Meanwhile, by means of the
inverted conical frustum flank 506, the colliding possibility the
conical frustum eccentric roundel 502 with the operating hole 61 in
the pump head body 60 is eliminated even the outer diameter of the
conical frustum eccentric roundel 502 is enlarged.
[0229] Moreover, under the same acting force F, the rebounding
force Fs is inversely proportional to the contact area. By means of
the enlarged outer diameter of the inverted conical frustum
eccentric roundel 502, the contact area of the sloped top ring 508
with the bottom side of the diaphragm membrane 70 is increased (as
ring A shown in FIG. 121) so that all distributed components of the
rebounding force Fs for the inverted conical frustum eccentric
roundels 502 of the present invention are further reduced.
[0230] Therefore, by means of the inverted conical frustum
eccentric roundel 502 in the present invention, some benefits are
obtained as below.
[0231] 1. The durability of the diaphragm membrane 70 for
sustaining the pumping action of high frequency from the inverted
conical frustum eccentric roundel 502 is mainly enhanced.
[0232] 2. The power consumption of the five-compressing-chamber
diaphragm pump is tremendously diminished due to less current being
wasted in the "squeezing phenomena" of high frequency.
[0233] 3. The working temperature of the five-compressing-chamber
diaphragm pump is tremendously subdued due to less power
consumption being used.
[0234] 4. The annoying noise of the bearing incurred by the aged
lubricant in the five-compressing-chamber diaphragm pump, which is
expeditiously accelerated by the high working temperature, is
mostly eliminated.
[0235] 5. The service lifespan of the five-compressing-chamber
diaphragm pump is further prolonged because all distributed
components of the rebounding force Fs for the inverted conical
frustum eccentric roundels 502 of the present invention are further
reduced.
[0236] Please refer to FIGS. 122 through 125, which are
illustrative figures of "five-compressing-chamber diaphragm pump
with multiple effects" in an adapted mode of for the ninth
exemplary embodiment of the present invention.
[0237] The cylindrical eccentric roundel 52 is adapted into a
combinational eccentric roundel 502 in an eccentric roundel mount
500. The combinational eccentric roundel 502 basically comprises a
roundel mount 511 and an inverted conical frustum roundel yoke 521
in detachable separation such that the outer diameter of the
conical frustum roundel yoke 521 is enlarged but still smaller than
the inner diameter of the operating hole 61 in the pump head body
60, wherein said roundel mount 511, which is a two-layered frustum,
includes bottom-layer base with a positional crescent 512 facing
inwardly and a top-layer protruded cylinder 513 with a central
female-threaded bore 514; and said inverted conical frustum roundel
yoke 521, which is to sleeve over the corresponding roundel mount
511, includes an upper bore 523, a middle bore 524 and a lower bore
525 stacked as a three-layered integral hollow frustum, as well as
an inverted conical frustum flank 522 and a sloped top ring 526
created from the upper bore 523 to the inverted conical frustum
flank 522 such that the bore diameter of the upper bore 523 is
bigger than the outer diameter of the protruded cylinder 513, the
bore diameter of the middle bore 524 is equivalent to the outer
diameter of the protruded cylinder 513 while the bore diameter of
the lower bore 525 is equivalent to the outer diameter of the
bottom-layer base in the roundel mount 511, and a positioning
dented ring 515 created between the protruded cylinder 513 and the
inside wall of the upper bore 523 upon having the conical frustum
roundel yoke 521 sleeved over the roundel mount 511 (as shown in
FIGS. 124 and 125).
[0238] Please refer to FIG. 126, which is illustrative figure for
the assembly in the adapted mode of the "five-compressing-chamber
diaphragm pump with multiple effects" in an adapted mode of for the
ninth exemplary embodiment of the present invention.
[0239] Firstly, sleeve the conical frustum roundel yoke 521 over
the roundel mounts 511;
[0240] Secondly, insert all five annular positioning protrusions 76
of the diaphragm membrane 70 into five corresponding positioning
dented rings 515 in five combinational eccentric roundels 502 of
the eccentric roundel mount 500; and
[0241] Finally, by running each fastening screw 1 through the each
corresponding tiered hole 81 of pumping piston 80 and each
corresponding acting zone hole 75 in each piston acting zone 74 of
the diaphragm membrane 70, then securely screw the fastening screw
1 to firmly assembly the diaphragm membrane 70 and five pumping
pistons 80 on five corresponding female-threaded bores 514 in five
roundel mounts 511 of the eccentric roundel mount 500 (as enlarged
view shown in FIG. 126 of association).
[0242] Please refer to FIGS. 127 to 129, which are illustrative
figures for the operation in the adapted mode of the
"five-compressing-chamber diaphragm pump with multiple effects" in
an adapted mode of for the ninth exemplary embodiment of the
present invention.
[0243] Firstly, when the motor 10 is powered on, the wobble plate
40 is driven to rotate by the motor output shaft 11 so that five
combinational eccentric roundels 502 on the eccentric roundel mount
50 orderly move in up-and-down reciprocal stroke constantly;
[0244] Secondly, five piston acting zones 74 in the diaphragm
membrane 70 are orderly driven by the up-and-down reciprocal stroke
of five combinational eccentric roundels 502 to move in up-and-down
displacement;
[0245] Thirdly, when the combinational eccentric roundel 502 in the
present invention moves in "up stroke" with piston acting zone 74
in up displacement, an acting force F will obliquely pull the
partial portion between corresponding annular positioning
protrusion 76 and outer raised brim 71 of the diaphragm membrane
70; and
[0246] Finally, by means of the sloped top ring 526 in the inverted
conical frustum roundel yoke 521 of the eccentric roundel mount
500, not only the susceptible breakage of the diaphragm membrane 70
caused by the "squeezing phenomena" of high frequency, which is
incurred by the rounded shoulder 57 in the conventional tubular
eccentric roundel 502 (as hypothetical dotted line shown in FIG.
128), is completely eliminated but also the rebounding force Fs of
the diaphragm membrane 70 caused by the acting force F is
tremendously reduced (as enlarged view shown in FIG. 128 of
association).
[0247] Moreover, under the same acting force F, the rebounding
force Fs is inversely proportional to the contact area. By means of
the enlarged outer diameter of the inverted conical frustum roundel
yoke 521, the contact area of the sloped top ring 508 with the
bottom side of the diaphragm membrane 70 is increased (as ring A
shown in FIG. 129) so that all distributed components of the
rebounding force Fs for the inverted conical frustum roundel yoke
521 of the present invention are further reduced.
[0248] Besides, the fabrication for the adapted mode of the
"five-compressing-chamber diaphragm pump with multiple effects" in
the ninth exemplary embodiment of the present invention is stepwise
shown as below.
[0249] Firstly, the roundel mount 511 and eccentric roundel mount
500 are fabricated together as an integral body;
[0250] Secondly, the conical frustum roundel yoke 521 is
independently fabricated as a separated entity; and
[0251] Finally, the conical frustum roundel yoke 521 and the
integral body of roundel mount 511 with eccentric roundel mount 500
are assembled to become a united entity combinational eccentric
roundel 502.
[0252] Thereby, the contrivance of the combinational eccentric
roundel 502 not only meets the requirement of mass production but
also reduces the overall manufacturing cost.
[0253] Therefore, by means of the combinational eccentric roundel
502 with conical frustum roundel yoke 521 in the present invention,
some benefits are obtained as below.
[0254] 1. The durability of the diaphragm membrane 70 for
sustaining the pumping action of high frequency from the inverted
conical frustum roundel yoke 521 is mainly enhanced.
[0255] 2. The power consumption of the five-compressing-chamber
diaphragm pump is tremendously diminished due to less current being
wasted in the "squeezing phenomena" of high frequency.
[0256] 3. The working temperature of the five-compressing-chamber
diaphragm pump is tremendously subdued due to less power
consumption being used.
[0257] 4. The annoying noise of the bearing incurred by the aged
lubricant in the five-compressing-chamber diaphragm pump, which is
expeditiously accelerated by the high working temperature, is
mostly eliminated.
[0258] 5. The service lifespan of the five-compressing-chamber
diaphragm pump is further prolonged because all distributed
components of the rebounding force Fs for the inverted conical
frustum roundel yoke 521 of the present invention are further
reduced.
[0259] 6. The manufacturing cost of the five-compressing-chamber
diaphragm pump is reduced because the present invention is suitable
for mass production.
[0260] Basing on the disclosure heretofore, the conclusion is that
the present invention substantially achieves the vibration reducing
effect of five-compressing-chamber diaphragm pump by means of
simple newly devised mating means for the pump head body and
diaphragm membrane without increasing overall cost so that it
solves all issues of the harassing noise and resonant shakes
incurred by the primary vibrating drawback in the conventional
five-compressing-chamber diaphragm pump. Additionally, by means of
simple sloped top ring for various cylindrical eccentric roundels
of the present invention, the service lifespan of the diaphragm
membrane in the five-compressing-chamber diaphragm pump can be
doubly extended, which indeed has valuable industrial
applicability. Accordingly, the present invention meets the
essential patentable criterion. Especially, the present invention
is simple with innovative novelty beyond the obviousness of the
prior arts, which meet the basic patentable criterion. Accordingly,
we submit the patent application to you for perusal in accordance
with related patent laws.
