Field of the Invention The present invention relates to a fluid transport device, and more particularly to a fluid transport device in which a power component indirectly drives a drive gear in a housing by magnetic induction. [Prior Art] A conventional fluid transporting device', as shown in Fig. 1, includes a housing 10, a driving gear 20, a driven gear 3, and a power element 40. The housing 10 is suitably shaped to accommodate the driving gear 2 and the driven gear 30, and is coupled to a cover u, and the driving gear 2 and the driven gear 30 mesh with each other. An input tube 1〇1 and an output tube 102 are respectively connected to the two adjacent walls of the housing 1 and the adjacent gears of the driving gear 2 and the driven gear 30. The power element 40 is provided with a shaft 41 that passes through the housing 10 and is coupled to the geometric center of the drive gear 2〇. The driven gear 30 is directly inserted into a corresponding shaft seat (not shown) inside the casing 1 and the cover 11 by a shaft 31. When the operation is performed, the input tube and the output tube 102 of the fluid delivery device are appropriately combined with a water-cooled heat dissipation module (not shown), and a fluid is input from the input tube 101, and the power element 4 is passed through the shaft. 41 driving the distal driving gear 20 to rotate (for example, rotating counterclockwise along the drawing surface), the driving gear 20 drives the driven gear 3 to synchronously rotate in the reverse direction (for example, clockwise rotation along the drawing surface). The convex teeth of the driving gear 2 (or the driven gear 30) drive the fluid to flow along the adjacent inner peripheral surface of the casing 1 and are rotated by the output pipe 102. In this way, the fluid 1259247, the transport device distributes the fluid of the water-cooled heat-dissipating module, and the device [= huahuan central processor chip] performs water cooling. The above conventional fluid conveying device has the following disadvantages, and the housing H) necessarily needs to open a shaft hole [not (four)] for the shaft cup 41 of the r: element 40 to pass through the housing 1 〇 to join the Drive gear 20,. However, there must be a gap between the outer surface of the shaft 41 and the inner surface of the shaft hole, which may cause fluid leakage. Even if the casing 1 () is provided with a gasket (not shown) on the outer side of the shaft hole, the problem of no phase loss at all is not ensured. In particular, when the fluid delivery device is applied to a water-cooling module of a computer, since it is normally operated in a high temperature environment, the shaft hole, the shaft Μ and the matching gasket of the housing 10 are both Frequent cold shrinkage will occur frequently and long-term use will also occur if the substrate is oxidized and/or negative (aging). As a result, the gap between the shaft 41 and the shaft hole γ is large, and the leakage of the fluid is increased. The fluid leaking will further cause the fluid conveying device S, the water cooling wire to heat up or the object to be cooled (for example, the central part of the computer) Processor W] rust #, short circuit, or even damage. For the above reasons, it is necessary to further improve the above-mentioned conventional fluid transporting device. In view of the above, the present invention improves the above-mentioned disadvantages, and the power component and the main reducer correspond to the respective setting components, and the power component and the f-moving gear are divided. In the corresponding position of the ship__ outside the casing, the power component can indirectly drive the driving gear in the casing to rotate, so that the leakage problem caused by the shaft passing through the casing does not occur. . In this way, the hair _ can improve the leakage prevention effect of the fluid transmission C:\Linda\PK Pat\PK992a doc ——7—— 1259247 the use of the guilty and prolonged fluid delivery device to further improve the fluid delivery device The service life.

The fixing member 401 is selectively fixed to the cover plate 11 by means of gluing, welding, snapping or screwing, and the power element 40 is selected to correspond to the driving gear 20 in a concentric manner. The power element 40 drives the shaft 41 to rotate to drive the rotor 42 to rotate. The rotor 42 is selected from a turntable or an outer rotor casing. The second magnetic sensing element 43 is selectively fixed to the rotor 42 by means of gluing, welding, snapping or screwing. The rotor 42 and the second magnetic sensing element 43 are rotatably received in the first recess 113 of the cover plate 11. The second magnetic sensing element 43 is a ring-shaped, rectangular-shaped or fan-shaped plate body made of a magnetic or magnetic conductive material. When the material is taken from the magnet, the second magnetic sensing element 43 has several The N and S pole regions have, for example, eight N and S pole regions. At least one of the first and second magnetic sensing elements 23, 43 is selected from a magnetic plate body to provide a source of magnetic drive power so that the two are pulled by magnetic force. Moreover, if the power component 40 is provided with a circuit board (not shown), the circuit board can be optionally accommodated in the second recess 114 of the cover plate 11. Alternatively, the power element 40 may be selectively coupled to the second magnetic sensing element 43 by the shaft 41, thereby omitting the rotor 42. Referring to FIGS. 2 and 3, when the fluid delivery device of the first embodiment of the present invention is operated, the power component 40 is powered by the rotor 41 to drive the rotor 42 and the second magnetic induction via the shaft 41. Element 43 rotates. Since the second magnetic sensing element 43 is concentrically disposed corresponding to the first magnetic sensing element 23 of the driving gear 20, when the N and S poles 1259247 of the second magnetic sensing element 43 are alternately rotated, the first magnetic sensing element 23, the effect of indirect magnetic induction will occur, which in turn causes the first magneto-sensitive element 23 to drive the drive gear 2 to rotate counterclockwise from the plane of the drive wire gear m2. At this time, the driving gear 2 带 drives the driven gear 30 g to rotate in the reverse direction by the spray-on method, for example, in the clockwise direction of the plane of the second drawing. Thereby, the projection of the driving gear 2 歯 drives the fluid input from the input pipe ι 〇 to flow along the adjacent inner circumferential surface of the casing 1 and is outputted by the output pipe 102. At the same time, the convex teeth of the driven gear 30 also flow with the punching fluid along the adjacent inner peripheral surface of the casing 1 and are rotated by the tube 102. More specifically, in the first embodiment of the present invention, the first and second magnetic sensing elements 23, 43 are used to connect the power element 40 to the external packaging unit (4). The method is turned to the wire of the casing 1 (4), so that the shaft 41 of the power component 40 does not need to pass through the seat m of the cover plate, so that the shaft 41 does not penetrate the casing. 〇 〇 街 街 街 《 流体 流体 流体 流体 流体.

Please refer to the fourth embodiment of the present invention, which discloses a fluid delivery device according to a second embodiment of the present invention. In contrast to the first embodiment, the second magnetic sensing element 43 of the power element 40 of the second embodiment is selected to be disposed eccentrically to the first magnetic sensing element 23 of the driving gear 20. Meanwhile, if the first and second magnetic sensing elements 23, 43 are all selected from magnets, the two may also have different numbers of Ν and S pole regions, for example, 4 and 8 N, s pole regions, respectively. Furthermore, C:\Limla\PK Pat\PK9!) 2fi. doc —12 — 〇5/||/〇|/|,. (1259247, the driving gear 20 and the driven gear 30 can be selected to form a disparity The size relationship, for example, the size and the number of teeth of the driving gear 20 can be designed to be significantly smaller than the size and the number of teeth of the driven gear 30, and vice versa. Further, the driving gear 20 and the driven gear 30 can also be selected in different numbers. With the above structure, when the N and S pole regions of the second magnetic sensing element 43 alternately rotate, the first magnetic sensing element 23 can also have the effect of indirect magnetic induction, thereby causing the first magnetic sensing element 23 to drive the active. The gear 20 and the driven gear 30 rotate to cause fluid flow. Thereby, the second embodiment of the present invention can improve the leakage preventing effect, the reliability of use and the service life of the fluid conveying device.

Compared with the first and second embodiments, the second magnetic sensing component 43 of the third embodiment of the power component 40 is also selected from the number of N, S pole " zone magnet, but the drive gear 20 The magnetic sensing element 23 is selected from a magnetically conductive plate body, such as an iron plate. The size of the first magnetic sensing element 23 is smaller than the size of the second magnetic sensing element 43, and preferably substantially equal to or smaller than the second magnetic The size of the N and S pole regions of the sensing element 43. Thereby, the power element 40 can also drive the driving gear 20 to rotate by the first and second magnetic sensing elements 23 and 43. Further, by appropriate design In the shape of the internal space 100 of the housing 10, the present invention only needs to utilize a single rotation of the driving gear 20 to properly drive the fluid from the side of the input tube 101 to the side of the output tube 102, thereby further omitting the setting of the driven gear. 30. Relatively simplified overall configuration. As described above, the force element 259247 of the conventional fluid transport device of FIG. 1 is passed through the housing 10 with the shaft 41 to drive the drive gear 20 so that The present invention has the disadvantages of forming a gap to cause fluid leakage, and the present invention in FIG. 2 is provided with the first and second magnetic sensing elements 23 and 43 corresponding to the driving gear 20 and the power component 40, so that the power component 40 is Magnetic induction can be used indirectly The driving gear 20 in the casing 10 is rotated. Thereby, the invention can effectively improve the leakage preventing effect of the fluid conveying device, thereby improving the reliability of use of the fluid conveying device and prolonging the service life of the fluid conveying device. The present invention has been disclosed by the above-described preferred embodiments, and is not intended to limit the scope of the invention, and various modifications and changes can be made without departing from the spirit and scope of the invention. This is subject to the definition of the scope of the patent application.
