Definitions

  • the present invention is related to a device for pushing a fluid, and more particularly to a unit utilizing current to control reciprocation for pushing fluids.
  • the conventional pumping device is used to push a fluid to flow in a pipeline.
  • the pumping device generally includes a water wheel apparatus or a pump unit communicating with a pipeline and externally connected with a motor.
  • the motor operates to drive the water wheel to rotate or drive the pump unit to reciprocally move for pushing, the fluid. Therefore, the fluid can be circulated in the pipeline or transferred from one place to another place.
  • the conventional pumping device is equipped with the motor so that the much room is occupied and the cost is relatively high.
  • one single pipeline system is often equipped with one single pump.
  • one single pumping device can be used in cooperation with two pipeline systems. In this case, many switch valves or check valves must be mounted on the two pipeline systems. This leads to high cost and inconvenience in use.
  • U.S. Patent No. 6,364,003 of this applicant discloses a device in which five magnets are disposed in a chamber.
  • the chamber is formed with several openings.
  • a coil provided with variable current direction serves to drive one of the magnets to reciprocally move so as to altemately push two fluids.
  • Such measure is applicable to liquid-cooled or phase-change cooling system. Especially, this measure can suck in the cold air in the environment to serve as a heat-absorbing coolant.
  • the same poles of the five magnets are directed to each other.
  • the unit utilizing current to control reciprocation for pushing fluids of the present invention includes a chamber, a magnet, a coil connected with a circuit, a first inlet, a first outlet, a second inlet, a second outlet, a first valve and a second valve.
  • the unit utilizing current to control reciprocation for pushing fluids of the present invention includes a chamber 11, a magnet 12, a coil 13, a first inlet 14, a first outlet 15, a second inlet 16, a second outlet 17, a first valve 18 and a second valve 19.
  • the chamber 11 has a certain length and two openings at two ends.
  • the chamber 11 can be a tubular body.
  • the magnet 12 has a certain length.
  • the shape of the outer circumference of the magnet 12 corresponds to the shape of the inner circumference of the chamber 11, whereby the magnet 12 is slidably disposed in the chamber 11.
  • the coil 13 is disposed on outer side of the chamber 11 and connected with a circuit.
  • the circuit provides a cyclically variable or a variable current direction for the coil 13 for driving the magnet 12 to reciprocally move.
  • the first inlet 14 and first outlet 15 are disposed at one end of the chamber 11.
  • the second inlet 16 and second outlet 17 are disposed at the other end of the chamber 11.
  • the first valve 18 is disposed between the first inlet 14, the first outlet 15 and the chamber 11.
  • the first valve 18 is movable between a first position and a second position. In the first position, the first valve 18 blocks the first inlet 14 without blocking the first outlet 15. In the second position, the first valve 18 blocks the first outlet 15 without blocking the first inlet 14.
  • the second valve 19 is disposed between the second inlet 16, the second: outlet 17 and the chamber 11.
  • the second valve 19 is movable between a third position and a fourth position. In the third position, the second valve, 19 blocks the second inlet 16 without blodcing the second outlet 17. In the fourth position, the second valve 19 blocks the second outlet 17 without blocking the second inlet 16.
  • the unit utilizing current to control reciprocation for pushing fluids of the present invention has the following advantages:
  • the present invention further includes an outgoing connecting section 20 of a pipeline, an incoming connecting section 21 of a pipeline 21, a first communicating section 22, a second communicating section 23, a third communicating section 24 and a fourth communicating section 25.
  • the first communicating section 22 serves to communicate the first inlet 14 and the outgoing connecting section 20 of the pipeline.
  • the second communicating section 23 serves to communicate the second inlet 16 and the outgoing connecting section 20 of the pipeline.
  • the third communicating section 24 serves to communicate the second outlet 17 and the incoming connecting section 21 of the pipeline.
  • the fourth communicating section 25 serves to communicate the first outlet 15 and the incoming connecting section 21 of the pipeline.
  • the present invention can more easily connect the pipeline and achieve the transferring function.
  • the present invention further includes a first enclosing member 32.
  • the first enclosing member 32 encloses the coil 13 and surrounds the chamber 11 and can be made of metal material for forming more effective magnetic path to act the magnet 12. Furthermore, two ends of the first enclosing member 32 can respectively extend and bend suitable length into the chamber 11. It can achieve more effective magnetic path and field to act the magnet 12.
  • the present invention further includes a second enclosing member.
  • the second enclosing member encloses the first enclosing member 32 and the chamber 11.
  • the second enclosing member can be a sleeve made of nonmetallic material or metal material such as copper for achieving protective effect.
  • the present invention further includes a coating coated on inner or outer face of the second enclosing member.
  • the coating can be a metal coating such as nickel.
  • the coating can be a nonmetallic coating such as resin. The coating serves to enhance the protection effect or achieve a beautifying effect.
  • the present invention further includes a surrounding section fitted around the magnet 12 between the inner face of the chamber 11 and the magnet 12.
  • the surrounding section serves to contact with the inner face of the chamber 11 to achieve a true watertight or airtight effect.
  • the surrounding section can include two piston rings respectively disposed at two ends of the magnet 12.
