Description

Technical Field

[0001] This utility model relates to the technical field of water supply equipment for tobacco planting, specifically to a small water pump device. Background Technology

[0002] Tobacco cultivation requires regular irrigation. Traditional water pumps often use impellers made of a single metal or plastic material with simple blade structures. This leads to turbulence and vortices in the water flow within the pump chamber, resulting in increased energy loss and an efficiency generally below 50%. Furthermore, some water pumps employ a straight-through flow channel design, lacking optimized flow guidance structures, which further reduces fluid transport efficiency. Utility Model Content

[0003] This invention provides a small water pump device that solves the problems of high energy consumption and low efficiency of existing water pumps for tobacco planting irrigation.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A small water pump device includes a pump body, a drive motor, and an impeller. The pump body has an inlet and an outlet. The drive motor is mounted on the pump body, and the impeller is mounted on the main shaft of the drive motor.

[0006] The pump body has a spiral water flow channel inside; the impeller blades have an array of micro-dimples on their surface.

[0007] Furthermore, the inlet and outlet are provided with quick-connect interfaces, and the end face of the quick-connect interfaces is provided with a rubber sealing ring.

[0008] Furthermore, a shock-absorbing coupling mechanism is provided between the drive motor and the pump body, the shock-absorbing coupling mechanism including a rubber pad and a spring damper.

[0009] Furthermore, the diameter of the micro-pit array is 0.5-1 mm, the depth is 0.2-0.3 mm, and the center-to-center distance between adjacent pits is 1.5 times the pit diameter.

[0010] Furthermore, the drive motor is an external rotor brushless motor, and the motor stator is bonded to the pump body through a thermally conductive silicone layer.

[0011] Furthermore, the inner wall of the spiral water flow channel is provided with guide ribs, which are distributed in an involute pattern.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0013] In practical operation, the spiral water flow channel reduces turbulence, improving efficiency by more than 15% compared to the traditional straight channel design; the array of micro-dimples on the impeller blade surface disrupts the water flow boundary layer, reducing turbulence and vortices. Using this invention can reduce energy loss and improve working efficiency. Attached Figure Description
