Description

Technical Field

[0001] The utility model relates to the field of cleaning equipment, in particular to a sewage tank structure. Background Art

[0002] In the related art, the sewage tank of a handheld cleaning device is mostly configured on the main body. When the handheld cleaning device is working in a lying state, that is, the main body is in a state approximately parallel to the ground, the sewage in the sewage tank is likely to backflow. If backflow occurs, it will affect the service life of the vacuum motor. At present, a surge protection structure is mostly used to solve the problem of sewage surge backflow, but the effect is very little. The reason is that the air extraction port of the sewage tank is mostly arranged at the top of the tank body. When the main body is tilted, the air extraction port moves to the side of the sewage tank. In the surge state, the distance between the sewage and the air extraction port is greatly shortened, and the sewage is extremely easy to be sucked into the vacuum motor.

[0003] Therefore, in view of the deficiencies of the existing technology, it is necessary to design a sewage tank structure to solve the above problems. Summary of the Utility Model

[0004] In order to overcome the above deficiencies in the existing technology, the purpose of the utility model is to provide a sewage tank structure.

[0007] A tank cover, the tank cover is detachably covered on the top of the tank body, and the bottom of the tank cover is provided with a frame structure corresponding to and matching the open structure; a boss is provided on the bottom of the tank cover and outside the frame structure, and an air extraction port is provided at the bottom of the boss, and the air extraction port extends inward to communicate with the inner circle of the frame structure; a water baffle is provided on the bottom of the tank cover and inside the inner circle of the frame structure;

[0008] In the assembled state, the frame structure is hermetically connected to the open structure, and the water baffle is arranged between the sewage suction pipe and the air extraction port.

[0009] The preferred technical solution is: the water baffle is composed of a horizontal plate and two side plates, the horizontal plate is arranged between the sewage suction pipe and the air extraction port, and the two side plates are connected to both sides of the horizontal plate and surround both sides of the sewage suction pipe.

[0010] The preferred technical solution is: a horizontally arranged water baffle is provided on the bottom side of the air extraction end corresponding to the air extraction port inside the inner circle of the frame structure.

[0011] The preferred technical solution is that the water outlet end of the sewage suction pipe is inclined towards the side of the water baffle.

[0012] The preferred technical solution is that a brush cover structure matching the roller brush is formed on the box cover.

[0013] Due to the application of the above technical solution, the beneficial effects of the present utility model are as follows:

[0014] A sewage tank structure provided by the present utility model can be assembled on the floor brush head of a cleaning device. By arranging a water baffle between the water outlet end of the sewage suction pipe and the air extraction port, the sewage sucked up can be prevented from being directly sucked away, and by designing the water outlet end of the sewage suction pipe to face the water baffle, the possibility of sewage being sucked into the vacuum motor is further reduced; in addition, the water baffle is equivalent to being inserted into the box body and also functions as a surge plate, reducing the possibility of sewage surging in the sewage tank.
