Brief Patent Description - Full Patent Description - Patent Application Claims
BACKGROUND OF THE INVENTION [0001] The present invention is related to a device for driving a fluid, and more particularly to a pump unit for magnetically driving an article. [0002] 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. [0003] The conventional pumping device is equipped with the motor so that the much room is occupied and the cost is relatively high. Also, one single pipeline system is often equipped with one single pump. Alternatively, 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. [0004] U.S. Pat. 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 alternately 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. When assembled, it should be noted that the same poles of the five magnets are directed to each other. SUMMARY OF THE INVENTION [0005] It is therefore a primary object of the present invention to provide a pump unit for magnetically driving an article. The pump unit employs one single magnet for driving a fluid. [0006] It is a further object of the present invention to provide the above pump unit which is able to drive the fluid of a pipeline system or the fluid of two independent pipeline systems. [0007] It is still a further object of the present invention to provide the above pump unit by which it is unnecessary to equip the external pipeline system with any switch valve or check valve. [0008] According to the above object, the pump unit for magnetically driving an article of the present invention includes a main body, an article, a coil and four one-way valve sections. [0009] The present invention can be best understood through the following description and accompanying drawings wherein: BRIEF DESCRIPTION OF THE DRAWINGS [0010] FIG. 1 is a sectional view of a first embodiment of the present invention; [0011] FIG. 2 is a sectional view of a second embodiment of the present invention; [0012] FIG. 3 is a sectional view of a third embodiment of the present invention; [0013] FIG. 4 is a sectional view of a fourth embodiment of the present invention; and [0014] FIG. 5 shows the operation of the pump unit of the present invention and also shows the path of the fluid. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS [0015] Please refer to FIG. 1. The pump unit for magnetically driving an article of the present invention includes a main body 11, an article 12 and a coil 13. [0016] The main body 11 can be a tubular body having a certain length and an internal chamber. [0017] The article 12 has a certain length and a configuration corresponding to the shape of the chamber. The article 12 is reciprocally movably positioned in the chamber. The article 12 can be a magnet or a superconductor subject to the action of magnetic force. [0018] The coil 13 is wound around the main body 11 and connected with a circuit. The circuit provides a current such as an alternate current or a periodically alternate current for the coil 13 so as to drive the article 12 to move or reciprocally move for pushing a fluid on one side or two sides of the article 12. [0019] In addition, at least an outer circumference of the main body is disposed with or formed of a magnetically conductive material such as silicon steel, iron, amorphous material (such as amorphous Si), permanent magnet and superconductor. The main body 11 can be formed of a sheet body spirally continuously wound into a circular tubular body. Alternatively, the main body 11 can be composed of multiple circular sleeves having different diameters and fitted with each other. [0020] Referring to FIG. 2, another structure of the main body 11 includes a circular tubular body 111 having a chamber and a magnetic conductor 112 enclosing the circular tubular body 111. The magnetic conductor 112 can be made of silicon steel, iron, amorphous material, permanent magnet or superconductor. The magnetic conductor 112 can be formed of a sheet body spirally continuously wound around the circular tubular body 111. Alternatively, the magnetic conductor 112 can be composed of multiple circular sleeves with different diameters. The sleeves are fitted around the circular tubular body 111 and fitted with each other. Continue reading about Pump unit for magnetically driving an article...
