A baffle is located at the bottom of the lead screw guide rail, and a lifting motor is located at the other end. Two sliding rails are located at the bottom of the sofa body, with a dust collection plate between the sides of the two sliding rails. A dust baffle is located on one side of the sofa body, and transmission devices are located on both sides of the dust collection plate. This invention effectively improves the cleanability of the sofa, while also being easy to operate and suitable for widespread application.

[0004] While the aforementioned patents can clean the back of a sofa, the back of the sofa is usually placed against a wall during use. Relatively speaking, the sofa cushions are used most frequently and tend to accumulate a lot of dust, dander, and other impurities, which can affect the user's health. Manual cleaning is also quite cumbersome and causes considerable inconvenience to the user.

[0005] Therefore, sofas with self-cleaning functions are urgently needed to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to solve the problem that dust, dander, and other impurities on sofa cushions are inconvenient to clean and can easily affect the user's health in the existing technology, and to propose a sofa with an automatic cleaning function.

[0014] As a preferred technical solution of this application, the bottom of the side panel is equipped with legs for supporting the sofa.

[0015] Compared with the prior art, this utility model provides a sofa with an automatic cleaning function, which has the following beneficial effects:

[0016] 1. This sofa with automatic cleaning function, through the setting of a rotating ring sofa cushion and the cleaning mechanism that works with it, realizes that the ring sofa cushion is driven by a motor to rotate, and the cleaning mechanism cleans the dust, dander and other impurities on the surface of the sofa cushion. This solves the problems of the inconvenience of cleaning the surface of the sofa cushion and the time-consuming and laborious manual cleaning in the prior art.

[0017] 2. This sofa with automatic cleaning function uses a brush plate that slides through the frame. With the help of a spring telescopic rod between the brush plate and the frame, the brush plate is pushed closer to the circular sofa cushion by elastic force, so that the bristles on the brush plate are closer to the circular sofa cushion, improving the cleaning effect. This solves the problem of poor cleaning effect caused by the constant distance between the brush plate and the circular sofa cushion and the lack of pressure in the existing technology.
