In existing water pumps and water tanks, after the water pump is started, it is difficult to exhaust the air inside the pump head, and the water pump needs to be repeatedly started and stopped or shaken to solve the problem. For water pumps with higher power, a vortex will be generated at the water inlet, and more liquid must be used to maintain a higher water level to eliminate the vortex caused by the negative pressure at the inlet.

Example 1

[0027] See also Figure 1 to Figure 2 The present embodiment provides a water pump head, which is provided with a water inlet 3 and a water outlet 4. The water pump head is provided with a water inlet channel 5 connected with the water inlet 3, a rotating channel 6 connected with the water inlet channel 5, and a water retaining wall 7 separating the water inlet channel 5 from the rotating channel 6. A pump cavity water inlet 8 is provided in the center of the water pump head.

[0028] Water-cooling equipment is usually fixed on the machine in advance. Some equipment needs to be added with liquid for debugging during production, but the liquid needs to be emptied when it is sent to the terminal. For example, it is very troublesome to carry liquid when sending abroad; it will be very troublesome to add liquid when the terminal receives the equipment, and it may be necessary to repeat the operation to empty the air. Therefore, the water pump 1 provided in the present application has a water inlet channel 5 connected to the water inlet 3, a rotating channel 6 connected to the water inlet channel 5, and a water retaining wall 7 separating the water inlet channel 5 from the rotating channel 6 in the pump head of the water pump 1, which can solve the problem of vortex generated at the water inlet of the water pump 1 after the water pump 1 is started.

[0029] As described above, a water inlet 3 is arranged on the side of the water pump 1, and the water inlet 3 is connected to the water inlet channel 5, the water inlet channel 5 is a straight hole, and a water retaining wall 7 is arranged between the water inlet channel 5 and the rotating channel 6, and the water retaining wall 7 is arranged in front of the water inlet 3, so that the water coming in at a high speed no longer forms a vortex.

[0030] In this embodiment, the water retaining wall 7 is arranged in front of the water inlet channel 5, which can play a role in organizing the water flow to form a vortex.

[0031] In this embodiment, the communicating channel between the water inlet 3 and the water inlet channel 5 is a straight hole channel, and the straight hole can reduce the difficulty of processing. Example 2

The defoaming mesh cover 9 greatly reduces the generation of bubbles during the operation of the water pump 1, thereby reducing the cavitation effect of bubbles on the impeller.

[0034] In this embodiment, the first water passage 10 is arranged along the vertical direction of the defoaming mesh cover to form a grid-like structure. Preferably, the second water passage 11 is arranged along the circumference of the top of the defoaming mesh cover. The structural arrangement of the first water passage 10 and the second water passage 11 can facilitate water flow and reduce the generation of bubbles.

[0035] In this embodiment, a boss 12 for installation is provided at the bottom of the defoaming mesh cover 9. Preferably, a step is provided on the pump head side wall of the water pump 1 to match the boss 12 on the defoaming mesh cover 9 for installing the defoaming mesh cover 9.
