Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention is related to a pump device and
particularly to a pump device, which has a main body with an inlet,
an outlet and a receiving space therein, a magnetizing device
outside the main body and a magnetic device in the receiving space
corresponding to the magnetizing device.
[0003] 2. Brief Description of Related Art
[0004] Taiwanese Patent Publication No. 520008 (Application No.
91200922), entitled "WATER PUMP STRUCTURE" discloses a water pump,
which includes a motor, which is disposed in the water pump and has
an outer casing integrally joined to and disposed in the pump, a
shaft being disposed at a lateral side of the motor, a blade wheel
being attached to the shaft. The shaft and the blade wheel are
disposed in the pump and the motor is heat dissipated with water.
The preceding prior art has the motor being received in the water
pump and the blade wheel, which is connected to the motor, rotates
to actuate the water flow. In order to prevent the motor from
contacting the water, a water resistant device has to be added in
the pump so that it increases the fabrication cost of the water
pump. Further, the water resistant device may create clearances
after being used a long period due to fatigue effect such that the
water penetrates the motor via the clearance to result in damage of
the motor. Moreover, the water pump has to provide a fluid passage
in addition to receiving the motor so that a huge size is required
and it makes the water pump impractical.
SUMMARY OF THE INVENTION
[0005] An object of the present invention is to provide a pump
device, which is actuated with a magnetic device to pump the liquid
by way of magnetic inductance.
[0006] Another object of the present invention is to provide a pump
device, which isolates the fluid from the electrical device, for
preventing the fluid from being conductive.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0016] A pump device of the present invention in a preferred
embodiment thereof includes a main body 11, a magnetizing device
and magnetic device.
[0017] Referring to FIGS. 1 and 2, the main body 11 is composed of
non-magnetized material and the main body 11 has a receiving space
111 with an inlet 112 and an outlet 113 respectively disposed at
two ends of the receiving space 111. A stator set 12 provides
silicium steel plates 122 with coil sets 123 and has a through hole
121 corresponding to the main body 11 so that the stator set 12 can
fit with the main body 11. The magnetic device is composed of a
magnet 13, a blade wheel rotor 14 and annular bearings 15, 17. The
blade wheel rotor 14 is fixedly attached with fan blades 141 and
has an axial hole 142 for being rotationally pierced with a shaft
143. The blade wheel rotor 14 fits with a cylindrical shell 16 and
each of the annular bearings 15, 17 is fixedly attached with spokes
152, 172 for fixing a bearing 153, 173 respectively. During
assembling the pump device, the blade wheel rotor 14 is sleeved in
the cylindrical shell 16 and the cylindrical shell 16 further is
fitted in the magnet 13 such that the magnet 13, the cylindrical
shell 16 and the blade wheel rotor 14 can be joined together. Then,
the shaft 143 is arranged to pass through the axial hole 142 of the
blade wheel rotor 14 and the assembly composed of the magnet 13,
the cylindrical shell 16, the blade wheel rotor 14 and the shaft
143 with the annular bearings 15, 17 is received in the receiving
space 111 in a way of both ends of the shaft 143 being rotationally
attached with bearings 153, 173 of the annular bearings 15, 17
respectively so as to allow the magnet 13 keeping in a state of
balance without colliding the inner wall surface of the receiving
space 111. Next, the stator set 12 fits with the main body 11 and
is disposed to correspond to the magnet 13 in the receiving space
111.
[0018] Referring to FIGS. 3 and 4, when the current flows through
the coil set 123, a magnetic field can be constituted and the
silicium steel plates 122 are also induced a magnetic field. Once
the magnet 13 occurs magnetic field effect with the silicium steel
plates 122, the blade wheel rotor 14 can be driven to rotate in the
receiving space 111. The fluid 18 can be sucked into the main body
11 via the inlet 112 and drawn out from the outlet 113 via the
receiving space 111 while the blade wheel rotor 14 rotates. Thus,
the fluid 18 can be segregated from the electric apparatus
completely to prevent the fluid 18 from contacting the electricity
directly and occurring conductive effect. Further, the flow rate
and flow speed of the fluid 18 can be increased to obtain maximum
running efficiency as long as the blade wheel rotor 14 is actuated
to a little running capacity.
[0019] Referring to FIGS. 5 and 6, the pump device according to the
present invention in another embodiment thereof is illustrated. The
main body 21 is made of non-magnetized material and the main body
21 has a receiving space 211 with an inlet 212 and an outlet 213
being formed at each of two ends of the main body 21. A coil 22 has
a coil spool 221 with a through hole 223 corresponding to the main
body 21 so as to fit with the main body 21 and a lead wire 222 is
coiled on the coil spool 221. The magnetic device is composed of a
movable magnetic plunger 24 and annular bearings 25, 27. The
magnetic plunger 24 is provided with a through hole 241 for being
pierced by the shaft 242 and rotationally joining with the shaft
241. The annular bearings 25, 27 at the annular parts 251. 271
thereof are fixedly attached with secure ribs 252, 272 respectively
for fixing the bearings 253. 273. During assembling the pump
device, the shaft 242 is arranged to pass through and rotationally
join with the through hole 241 of the movable magnetic plunger 24.
Then, the assembly of the movable magnetic plunger 24 and the shaft
242 with the annular bearings 25, 27 is disposed in the receiving
space 211 of the main body 21 in a way of the shaft 242
rotationally joining both ends thereof with the bearings 253, 273
of the annular bearings 25, 27 such that the movable magnet plunger
24 can move forward and backward along the shaft 242 between the
annular bearings 25, 27 in the receiving space 211. Further, the
coil 22 is sleeved in the main body 21 in a way of corresponding to
the movable magnetic plunger 24.
[0020] Referring to FIGS. 7 and 8, when the coil 22 is magnetized
with the current to produce a magnetic field and to occur magnetic
effect with the movable magnetic plunger 24, the movable magnetic
plunger 24 can move forward and backward along the shaft 242
between the annular bearings 25, 27 in the receiving space 211 of
the main body 21. The fluid 28 flows into the receiving space 211
of the main body 21 via the inlet 212 during the movable magnetic
plunger 24 moving backward and is pressed by the movable magnetic
plunger 24 to flow out via the outlet 213 during the movable
magnetic plunger 24 moving forward. Because the fluid 28 directly
moves through the main body 21 to be separated from the electric
apparatus completely, it is possible to prevent the fluid 28 from
contacting with electricity and occurring conductive effect.
[0021] While the invention has been described with referencing to
preferred embodiments thereof, it is to be understood that
modifications or variations may be easily made without departing
from the spirit of this invention, which is defined by the appended
claims.
