Description

TECHNICAL FIELD

[0001] The utility model relates to a cleaning equipment technical field, especially a sewage tank structure. BACKGROUND

[0002] In the related art, the sewage tank of the handheld cleaning equipment is usually arranged on the main machine, and when the handheld cleaning equipment is in a flat working state, that is, the main machine is in a state of being approximately parallel to the ground, sewage in the sewage tank is prone to backflow, which may affect the service life of the vacuum motor. At present, a surge protection structure is usually used to solve the problem of sewage backflow, but the effect is not obvious. The reason is that the air suction port of the sewage tank is usually arranged on the top of the tank body, and when the main machine is tilted, the air suction port is transferred to the side of the sewage tank. In the surge state, the distance between the sewage and the air suction port is greatly shortened, and the sewage is easily sucked into the vacuum motor.

[0003] Therefore, in view of the deficiencies in the prior art, it is necessary to design a sewage tank structure to solve the above problems. SUMMARY

[0004] To overcome the deficiencies in the prior art, the utility model aims at providing a sewage tank structure.

[0005] To achieve the above-mentioned purposes and other related purposes, the technical scheme provided by the utility model is as follows: a sewage tank structure, comprising a tank body, wherein the bottom of the tank body is provided with a sewage suction port. The sewage suction port extends inward to form a sewage suction pipe, the top of the tank body is provided with a downwardly extending water baffle cover, the projection of the water baffle cover in the plane is in the shape of U and surrounds the rear side of the sewage suction pipe, the top of the tank body is provided with an air suction port, and the air suction port is located at the rear side of the water baffle cover.

[0006] The preferred technical scheme is that the pipe opening of the sewage suction pipe is inclined towards the rear side.

[0007] The preferred technical scheme is that a first sink is formed on the tank body and around the sewage suction port, and a first sealing ring is embedded in the first sink.

[0008] The preferred technical scheme is that a second sink is formed on the tank body and around the air suction port, and a second sealing ring is embedded in the second sink.

[0009] The preferred technical scheme is that a membrane flap with a cross-shaped opening is arranged at the air suction port.

[0010] Due to the use of the above technical scheme, the utility model has the following beneficial effects:

[0011] The sewage tank structure disclosed by the utility model reduces the possibility of sewage suction into the suction port by setting the suction pipe opening towards one side of the water baffle, avoids sewage in the sewage tank from flowing back into the vacuum motor after shaking to form a surge in the non-use state by setting the membrane flap with a cross-shaped opening at the suction port, and prolongs the service life of the vacuum motor.
