Abstract

The invention relates to an anti-backflow sewage tank for a ground washing machine. The anti-backflow sewage tank comprises a tank body; a tank port, a water inlet pipe part and an exhaust pipe part are arranged on the box body, and the exhaust pipe part extends into the box body; an anti-backflow component comprises a water retaining sleeve, an air passing sleeve and a cover body and is mounted on the exhaust pipe part; a water retaining convex ring is formed on the water retaining sleeve, and the water retaining sleeve is mounted on the exhaust pipe part; a clamping convex ring is formed onthe air passing sleeve, an air passing hole is formed in the clamping convex ring, and the air passing sleeve is also sheathed on the exhaust pipe part; a clamping ring groove is formed in the cover body, and the cover body is clamped with the clamping convex ring on the air passing sleeve through the clamping ring groove in the cover body to shield the air inlet end of the exhaust pipe part. Theanti-backflow sewage tank for the ground washing machine, provided by the invention, has the advantages that the sewage backflow can be prevented in the process of overturning a handle lever to rotateby a cleaner, a vacuum pump is prevented from being burned out due to soaking in sewage, the service life of the ground washing machine is favorably improved, and the like. The invention further relates to the ground washing machine.
