AI Technical Summary

Technical Problem

Traditional pool machine drive motors rely on O-rings for sealing the bottom shell. The sealing performance is limited by the dimensional accuracy of the bottom shell. The airtightness cannot be tested independently during the production process, resulting in sealing defects being discovered only after the machine is assembled. This leads to high repair costs and the machine is prone to leaks during use. Deformation of the bottom shell also affects the motor's performance and increases production costs.

Method used

A sealing structure for a pool machine drive motor is designed, employing a detachable drive box assembly, including a rigid plastic drive box bottom shell and an upper shell, which are fixedly connected by screws. A sealing ring groove and sealing ring assembly are set on the contact surface to achieve independent testing and higher sealing performance.

Benefits of technology

The drive motor sealing structure is removable and can be tested independently, reducing repair costs, improving sealing performance and effectiveness, reducing water leakage caused by bottom shell deformation, and lowering production costs.

Description

Technical Field

[0001] This utility model relates to the field of swimming pool machine structure technology, and in particular to a sealing structure for a swimming pool machine drive motor. Background Technology

[0002] As a professional cleaning device, the core function of a pool scrubber relies on the coordinated operation of the drive motor and the base assembly. In traditional designs, the drive motor and base assembly are integrated into a single molded structure, meaning the motor mounting cavity and the main body of the base are formed as a whole through injection molding.

[0003] However, in the existing bottom shell and drive motor mounting structure, the motor compartment sealing of the traditional bottom shell relies on the O-ring rubber compression structure. Its sealing performance is limited by the dimensional accuracy of the bottom shell body. During the production process, it is impossible to conduct an independent airtightness test on the entire bottom shell. Sealing defects are often only detected after the whole machine is assembled, which increases the cost of rework. In addition, when the pool machine is in operation, the deformation of the bottom shell can cause water leakage, affecting the performance of the motor. Furthermore, the complex bottom shell structure has a high production cost.

[0004] There is a need for a new type of sealing structure for the drive motor of a swimming pool machine that can solve the problems mentioned above. Utility Model Content
