Description

Technical Field

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

[0002] At present, the structure of a portable floor washer on the market is as follows: it includes a cleaning main body and a handle rod, and the cleaning main body and the handle rod are connected by a universal joint. A water tank, a sewage tank, a vacuum pump and other devices are installed on the handle rod. The structure of its sewage tank is mostly like this: it includes a box body, a box opening is formed on the box body, a water inlet pipe part and an air extraction pipe part are formed on the box body, and the air extraction pipe part extends into the box body, and the air extraction pipe part is between the water inlet pipe part and the box opening; during use, the sewage tank is installed on the handle rod of the floor washer, a vacuum pump is installed below the sewage tank, the water inlet pipe part of the sewage tank is communicated with the sewage suction hole arranged on the cleaning main body through a water pipe, and the air extraction pipe part of the sewage tank is communicated with the air extraction port of the vacuum pump through an air passage, and the air passage is a cavity formed in the handle rod. The function of the sewage tank is to collect the sewage generated by the cleaning main body during the cleaning process. The sewage tank extracts the air in the box body from the air extraction pipe part of the box body through the vacuum pump, so that a negative pressure is formed in the sewage tank to suck away the sewage generated by the cleaning main body during the cleaning process.

[0003] In order to avoid sewage backflow and achieve solid-liquid separation, currently, a drainage cover is usually arranged between the sewage pipe part and the air extraction pipe part, and a filter plate is arranged in the sewage tank. The filter plate is usually arranged at the bottom side of the drainage cover, and the drainage cover is connected to the filter plate through two side plates. After the sewage is drained through the cover body and the side plates of the drainage cover, it will fall on the filter plate and then be filtered by the filter plate and discharged into the bottom space of the sewage tank. That is, when the height of the side plate is fixed, the solid collection space is actually controlled by the distribution positions of the two side plates. The existing solid waste collection space is small and difficult to meet the actual use requirements.

[0004] Therefore, in view of the deficiencies of the prior art, it is necessary to design a drainage cover structure applied to a sewage tank to solve the above problems. Summary of the Utility Model

[0005] In order to overcome the above deficiencies in the prior art, the purpose of the utility model is to provide a drainage cover structure applied to a sewage tank.

[0006] To achieve the above and other related objectives, the technical solution provided by the present utility model is: a drainage cover structure applied to a sewage tank, including a box body and a box cover hermetically disposed at the top opening of the box body. A drainage cover that can extend into the box body is connected to the bottom side of the box cover. A filter plate that can be hermetically connected to the inner wall of the box body is connected to the bottom side of the drainage cover. Filter holes are provided on the filter plate. The drainage cover is composed of a cover body and two side plates disposed on both sides of the cover body for connecting the filter plate. The two side plates are arranged in a flare shape and have a large opening side and a small opening side, and the large opening side is correspondingly arranged with the filter holes.

[0007] The preferred technical solution is: Mesh holes are provided on the side plates.

[0008] The preferred technical solution is: A suction port is provided on the box cover, and an anti-backflow cover corresponding to the suction port is provided on the bottom side of the box cover. The opening of the anti-backflow cover is arranged in the opposite direction to the user side.

[0009] The preferred technical solution is: A connecting rod is provided on the bottom side of the anti-backflow cover, and the bottom end of the connecting rod is fixedly connected to the top end of the cover body.

[0010] The preferred technical solution is: A liquid level sensor that can extend into the box body is further connected to the bottom side of the box cover, and the liquid level sensor is disposed outside the small opening side of the side plate.

[0011] Due to the application of the above technical solution, the beneficial effects of the present utility model are:

[0012] The drainage cover structure applied to the sewage tank proposed by the present utility model increases the solid waste collection space and improves the space utilization rate by arranging the two side plates in a flare shape and making the large opening side correspond to the filter holes. This structure is simple and ingenious. By simply adjusting the distribution position of the side plates, the solid waste collection space can be significantly increased, which is suitable for popularization and use.
