AI Technical Summary
Technical Problem
The existing water pump structure cannot effectively dissipate heat, especially when connected to circuit board components, which leads to the risk of overheating.
Method used
To promote heat dissipation, flow channels are added inside the stator, including through holes and flow channels in the stator housing. The flow channels connect the impeller and the rotor chamber at both ends and carry away heat through the fluid channels.
Benefits of technology
Effective heat dissipation reduces the temperature of the stator and circuit board, improving the efficiency and lifespan of the water pump structure.

Abstract
The utility model provides a water pump structure, comprising: a shell, a rotor and a stator. The shell has an inlet and an outlet. The rotor has an impeller and a rotor magnetic pole. The stator is used to rotate the rotor, comprising: a stator housing and a cladding body assembly. The stator housing has an upper housing and a lower housing. The upper housing and the lower housing are assembled to form a closed space, and the stator housing has at least a first through hole and at least a second through hole. The cladding body assembly is arranged in the closed space and covers a stator magnetic pole. The shell and the stator housing are assembled to form a rotor chamber, and the rotor magnetic pole is located in the rotor chamber. At least a first shunt channel is formed in the cladding body assembly. The first through hole, the first shunt channel and the second through hole sequentially form a flow channel, and the flow channel is connected to the impeller and the rotor chamber at the head and tail respectively. The water pump structure provided in the embodiment of the utility model adds a flow channel in the stator to promote heat dissipation, and can solve the heat dissipation problem.
