Benefits of technology

[0007] An object of the present invention is to provide a fluid pump for avoiding fluid leakage.
[0008] Another object of the present invention is to provide a fluid pump with improved operational reliability.
[0009] A further object of the present invention is to provide a fluid pump having a prolonged life.
[0025] Preferably, the first magnetically conductive member further comprises an insulating layer to avoid rusting.

Problems solved by technology

Even though gaskets are mounted on both sides of the hole of the housing 10, the leakage problem could not be completely solved.
As a result, the size of the gap between the shaft 41 and the circumferential wall delimiting the hole of the housing 10 increases, aggregating the leakage problem and leading to rusting, short circuit, and damage to the fluid pump, the heat-dissipating model, and the object.

first embodiment

[0038] Referring to FIG. 2, a fluid pump in accordance with the present invention comprises a housing 10, at least one drive gear 20, at least one driven gear 30, and a driving member 40. The fluid pump may drive a fluid to flow. For example, the fluid pump can be coupled with a fluid-cooling type heat-dissipating module (not shown) and drive a fluid to flow in a circulating way for dissipating an object (such as a central processing chip of a computer). The fluid pump can be used in other fluid mechanisms and operated in a similar way.

[0039] Referring to FIGS. 2 and 3, housing 10 is of an appropriate shape such as elliptic. The housing 10 includes an interior space 100, a first shaft seat 103, and a second shaft seat 104. A lid 11 and a washer (or gasket) 12 are mounted to cover and seal the housing 10. The drive gear 20 and the driven gear 30 are mounted in the interior space 100. An inlet pipe 101 and an outlet pipe 102 are mounted to opposite sides of the housing 10 at locations...

second embodiment

[0050]FIGS. 4 and 5 illustrate the fluid pump in accordance with the present invention, wherein the second magnetically inductive member 43 of the driving member 40 is eccentric to the first magnetically inductive member 23 of the drive gear 20. In a case that both of the first magnetically inductive member 23 and the second magnetically inductive member 43 are magnets, the number of the north pole sections N and south pole sections S of the first magnetically inductive member 23 may be different from that of the north pole sections N and south pole sections S of the second magnetically inductive member 43. Further, the drive gear 20 and the driven gear 30 may differ in size and in the number of teeth. For example, the size of the driven gear 30 may be larger than that of the drive gear 20 and the number of the teeth of the driven gear 30 may be greater than that of the drive gear 20, and vice versa. The number of the drive gear 20 and the driven gear 30 may vary according to need.

third embodiment

[0052]FIGS. 6 and 7 illustrate the fluid pump in accordance with the present invention, wherein the second magnetically inductive member 43 of the driving member 40 is a magnet with a plurality of north pole sections N and a plurality of south pole sections S whereas the first magnetically inductive member 23 of the drive gear 20 is a magnetically conductive plate such as an iron plate. The size of the first magnetically inductive member 23 is apparently smaller than that of the second magnetically inductive member 43 and preferably equal to or smaller than that of the north pole sections N and the south pole sections S of the second magnetically inductive member 43. The drive gear 20 is turned by the driving member 40 through use of the first and second magnetically inductive members 23 and 43. The interior space 100 of the housing 10 is designed to receive only the drive gear 20, as the driven gear 30 is omitted. The structure of the fluid pump is thus simplified. Rotation of the ...

Abstract

A fluid pump includes a housing having a sealed interior space, at least one drive gear mounted in the interior space of the housing for driving a fluid, a first magnetically inductive member coupled to the drive gear, a driving member mounted outside the housing; and a second magnetically inductive member driven by the driving member and located corresponding to the first magnetically inductive member. At least one of the first magnetically inductive member and the second magnetically inductive member is made of magnetic material to provide a magnetic force for mutual attraction therebetween. When the second magnetically inductive member is driven by the driving member, the first magnetically inductive member and the drive gear are turned to drive the fluid through indirect magnetic induction provided by the second magnetically inductive member outside the housing. Leakage of fluid is avoided.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a fluid pump, and more particularly to a fluid pump having a simplified structure for avoiding fluid leakage. [0003] 2. Description of Related Art [0004]FIG. 1 of the drawings illustrates a conventional fluid pump comprising a housing 10, a drive gear 20, a driven gear 30, and a driving member 40. The housing 10 receives the drive gear 20 and the driven gear 30 that mesh with each other. A lid 11 covers the housing 10. An inlet pipe 101 is connected to a first side of the housing 10 in a location adjacent to a joining area between the drive gear 20 and the driven gear 30. An outlet pipe 102 is connected to a second side of the housing 10 in a location opposite to the inlet pipe 101. The driving member 40 includes a shaft 41 extending through the housing 10 and a center of the drive gear 20. The driven gear 30 is extended through by a shaft 31 that is mounted to a seat (not shown) in ...
