Description
FIELD OF THE INVENTION
[0001] The present invention relates to a pump, more particularly,
relates to lessening a component number of the pump; simplifying a
fabrication procedure and an assembly procedure; and reducing a
friction noise from vibration.
DESCRIPTION OF THE RELATED ART
[0002] A prior art, "A radial-sliding-and-pushing pump", is
proclaimed in Taiwan. The prior art comprises a base, a rotor, a
sliding block and a towing member.
[0003] Therein, the base is formed with a disk having a surrounding
wall at its rim. The base has two sets of connecting pipes and each
set has two connecting pipes located at two radial ends separately.
Two inward arc protrusions are located on inner surface of the
surrounding wall at two radial ends separately. Each protrusion is
located between two neighboring connecting pipes at each one of the
radial ends. And a shaft of the disk is penetrated through an axis
hole.
[0004] The rotor is movably set in the surrounding wall. The outer
surface of the rotor is stuck to an arc surface of the protrusion.
Thus, a pair of flow paths is formed between the surrounding wall
and the rotor and is connected with the connecting pipes. An axis
rod on an end surface of the rotor penetrates out the base through
the axis hole for an outside driver to rotate the rotor. A sliding
channel at the opposite end surface of the rotor is set along an
axis radial and is penetrated out the outside rim of the rotor at
two ends of the sliding channel.
[0005] The sliding block is embedded in the sliding channel with a
length shorter than the sliding channel. The part of the sliding
channel which extends out of the sliding block forms a transferring
space to connect to the flow path. Two ends of the sliding block
are closely contacted with an inner surface of the protrusion. And
the middle section of the sliding block is concaved to obtain a
slot.
[0006] The towing member is embedded in the slot nestling to the
slot wall. The towing member is inserted with a positioning rod at
the center. And a shaft of the positioning rod is parallel to a
shaft of the rotor. The shaft of the positioning rod is located on
the line of two protrusions and is deviated from the shaft of the
rotor. The sliding block is towed by the towing member to
reciprocate a long the sliding channel. Thus, the transferring
space is used to transfer fluid.
[0007] The cover unit is covered on the top of the surrounding wall
to seal the flow path. And the positioning rod is fixed with the
cover unit to position the shaft of the towing member.
[0008] The prior art uses a towing member to reciprocate a sliding
block following the rotation of the rotor along a radial path so
that fluid in the fluid channel are pumped with sucking and pushing
motions. However, the prior art has a complex structure with a
running gear (a motor) at the outside. And a big noise is produced
when using the running gear. Hence, the prior art does not fulfill
users' requests on actual use.

DESCRIPTION OF THE PREFERRED EMBODIMENT
[0018] The following description of the preferred embodiment is
provided to understand the features and the structures of the
present invention.
[0019] Please refer to FIG. 1 to FIG. 3, which are a perspective
view, an explosive view and a cross-sectional view showing a
preferred embodiment according to the present invention. As shown
in the figures, the present invention is a pumping device,
comprising a base 1, a rotating unit 2, a driving unit 3 and a
cover unit 4, where components of the pumping device are few in
number; a fabrication procedure and an assembly procedure are
simplified; and a friction noise from vibration is reduced.
[0020] The base 1 has a containing space 11; a first indentation 12
and a second indentation 13 are set at the side surface of the base
1; and, the first indentation 12 and the second indentation 13 are
vented with a first hole 121 and a second hole 131
respectively.
[0021] The rotating unit 2 is movably set in the containing space
11 of the base 1; the rotating unit 2 has a motor 21; the motor 21
is connected with a rotor 22; the rotor 22 has a channel 221 on a
surface; and, the channel 221 has a first opening 222 and a second
opening 223 separately at two ends of the channel 221. The motor 21
can further connect to the rotating unit 2 from outside of the
rotating unit 2.
[0022] The driving unit 3 is set in the channel 221 of the rotating
unit 2 and has a long hole 31.
[0023] The cover unit 4 is coordinated with a fixing member 41 to
be fixed on an end surface of the base for covering the containing
space 11 of the base 1; the cover unit 4 has a shaft 42 on an end
surface of the cover unit 4 movably penetrating through the long
hole 31 of the driving unit 3; and, the shaft 42 has a bearing 43
for lubrication as required. Thus a novel pumping device is
obtained.
[0024] Please refer to FIG. 4, FIG. 5 and FIG. 6A to FIG. 6D, which
are a view showing a state of use and cross-sectional views at a
first direction and a second direction showing the state of use. As
shown in the figures, when using the present invention, a first
pipe 14 and a second pipe 15 are connected to a first hole 121 of a
first indentation 12 and a second hole 131 of a second indentation
13 respectively. The first pipe 14 is used as an input terminal;
and the second pipe 15 is used as an output terminal. (It is also
all right to use the first pipe 14 as an output terminal and the
second pipe 15 as an input terminal by reversing motor rotating
direction.) The input and output terminals input and output a work
fluid or gas; and are connected with an outside device. Thus, the
present invention is used in a heat dissipation system or simply a
pump which requires to transfer liquid or gas. An outside power is
applied to a motor 21 of a rotating unit 2 to move a rotor 22 by
the motor 21. And a long hole 31 of a driving unit 3 is coordinated
with a shaft 42 of a cover unit 4 to push the driving unit 3 to
slide in a channel 221 of the rotor 22. At first, the working fluid
or gas enters from the first hole 121 of the first indentation 12
through the first pipe 14. Between the first opening 222 and the
first indentation 12, a first interspace 51 is formed to let the
working fluid or gas flow in. When a first opening 222 and a second
opening 223 at two opposite ends of the channel 221 of the rotor 22
are corresponding to the first indentation 12 and the second
indentation 13 respectively, the rotor 22 rotates clockwise and the
driving unit 3 is moved toward the second indentation 13 and the
first opening 223 until the second indentation is sealed by the
rotor 22. The rotor 22 keeps rotating until the first opening 222
is corresponding to the second indentation 13. The working fluid or
gas in the first interspace 51 is pushed from the second hole 131
of the second indentation 13 to the second indentation 13 to be
outputted to the outside device through the second pipe. Thus, a
circle of transferring is finished. At the same time, the second
interspace 52 is formed by the second opening 223 and the first
indentation 12 at the opposite end; and the working fluid or gas
flows in. When the rotor 22 keeps rotating until the second opening
223 is corresponding to the second indentation 13 again, the
working fluid or gas in the first interspace 51 is pushed to the
second indentation 13 to be outputted from the second hole 131 of
the second indentation 13 to the outside device through the second
pipe. As shown in FIG. 6A to FIG. 6D, steps in a circle are shown.
Such a circle is run for 360 degrees; that is, there are two
circles run. Hence, the working fluid or gas is transferred with
low and saved energy.
[0025] To sum up, the present invention is a pumping device, where
component number of the device are few; the fabrication and the
assembly is thus simplified; friction noise of vibration is
reduced; and the energy is saved.
[0026] The preferred embodiment herein disclosed is not intended to
unnecessarily limit the scope of the invention. Therefore, simple
modifications or variations belonging to the equivalent of the
scope of the claims and the instructions disclosed herein for a
patent are all within the scope of the present invention.
