Abstract

The present invention refers to a water pump having a case provided with inner casing inside. A vane seat provided with a plural of vanes spaced with each other is disposed in the inner casing. A flowing passage is formed between the inner casing and the case. When liquid is sucked into the case, it flows into the inner casing though the flowing passage and is discharged from the case by the vane seat rotated in high speed. The flowing passage provides a cushion space for liquid flowing into the case, so liquid can flows into the case smoothly without obstruction even though the integral thickness of the water pump is reduced. Therefore, the suction of the water pump can retain a fixed value such that hole erosion will not appear in water pump, thereby, the efficiency of water pump will be hold in line.

Description

Water pump technology field'

The present invention relates to a water pump, that is, a pump capable of transporting a liquid. Background technique

Because the pump is convenient to use, it is widely used by people. Most of the pumps are used in the heat dissipation of the computer. Through the operation of the pump, the coolant passes through the heat generating processor, which lowers the temperature of the processor. importance.

The existing water pump, as shown in FIG. 6, has a housing 50. The bottom end of the housing 50 is provided with an opening. The housing 50 is provided with a chamber 5 1 and a housing 50. The outer side wall is respectively provided with a water inlet hole 5 2 and a water outlet hole 5 3 communicating with the chamber 5 1 , and a vane seat 5 4 driven by the rotor 5 5 is disposed in the chamber 5 1 , and the vane seat 5 4 has a plurality of pieces The blades are spaced apart from each other; a bottom cover 56 is attached to the bottom end of the housing 50, thereby closing the opening at the bottom end of the housing 50. In actual use, when the blade holder 54 starts to rotate at a high speed, suction is generated, and a liquid such as water or coolant is sucked into the casing 5 from the inlet hole 5 2 and then from the outlet hole 5 3 Out of the housing 50, the purpose of the liquid circulation is achieved.

However, the existing water pump still has its shortcomings. Since the mutual coupling between the housing 50 and the bottom cover 56 makes the existing water pump have a certain thickness, today's computers are all light, thin, short and small. The direction of development, so the existing water pump must reduce its overall volume, the opposite inlet hole 5 2 and the outlet hole 5 3 also have to reduce its aperture, when the high-speed flow of liquid through the smaller aperture of the inlet hole 5 2 The liquid will generate a great friction with the inner wall of the water inlet hole 52, and the friction will cause bubbles to be generated in the liquid. When the air bubbles gather to a certain amount, pitting corrosion occurs and the liquid is prevented from entering the casing 50. This reduces the effectiveness of existing pumps. The pump is then redesigned to design the pump of the present invention. Summary of the invention

The technical problem to be solved by the present invention is to provide a water pump whose suction force can be kept fixed, so that the pitting phenomenon does not occur, thereby maintaining the performance of the water pump.

The technical solution of the present invention is: a water pump having: a housing having a chamber having an opening therein, wherein the outer side of the housing is respectively provided with an outlet and a water inlet communicating with the chamber; An inner casing is disposed in the chamber of the casing, a flow passage is formed between the inner casing and the chamber, and a fan seat is disposed in the inner casing, and the side wall of the blade seat is provided with a plurality of mutual a spaced-apart vane, the top end of the inner casing is provided with an inlet, and an outlet pipe is formed at a position of the inner casing relative to the outlet of the casing, the outlet pipe extending outward from the outlet to the outside of the casing; It is fixed to the opening of the casing, and the cover body and the inner casing form a water channel.

a water pump, wherein a plurality of fixing holes are provided at an edge of the opening of the housing, and a hole is provided at a position of the cover body relative to the fixing hole, and a plurality of fixing members penetrate the through hole and the fixing hole Fixed to each other.

The water pump as described above, wherein the housing is a slightly circular structure.

The water pump as described above, wherein the housing is a slightly square structure.

The water pump as described above, wherein the inner casing is a scroll casing.

The water pump of the present invention has a casing, an inner casing is disposed in the casing, and a blade seat is disposed in the inner casing. The blade seat is provided with a plurality of blades spaced apart from each other, and the two blades are spaced apart from each other. There is a distance, and a water channel is formed between the inner casing and the casing, and the water channel is a buffer space.

The water pump having the above structure, when the liquid is sucked into the casing from the water inlet, the liquid flows into the inner casing through the flow passage, the water passage and the inlet, and then the fan blade seat that is rotated at a high speed exits the casing through the outlet pipe. The flow path and the water channel allow a buffer space when the liquid enters the housing. The buffer space allows the liquid to enter the housing without being hindered. Even if the pump reduces its overall thickness, the suction force of the water pump can be kept fixed, and the liquid does not cause pitting when it enters the housing, so the liquid A certain amount can be maintained into the housing to maintain the performance of the pump.
