[0002] In the related art, cleaning appliances need to complete cleaning by sucking gas to carry away dirt. A Chinese utility model patent proposed a sewage tank and a cleaning appliance (CN220309089U), and the sewage tank includes: a box body, a baffle plate, and a ribbing component. Among them, the box body is formed with a sewage inlet channel and an air outlet. The baffle plate is arranged inside the box body. The ribbing component is located inside the box body, and the ribbing component is connected to the baffle plate and / or the box body. The box body, the baffle plate, and the ribbing component enclose a first cavity and a second cavity that communicate with each other. The sewage inlet channel is located on one side of the ribbing component facing the first cavity, and the air outlet is located on one side of the ribbing component facing the second cavity.
[0003] During the actual use process, it is found that since the air outlet is directly arranged at the bottom side of the box cover in the above solution, when the floor washing machine is lying flat for use, the sewage will flow to the bottom side of the box cover and backflow into the suction source through the air outlet, thereby affecting the service life of the suction source.
[0004] Therefore, in view of the deficiencies of the existing technology, it is necessary to design a sewage tank structure for a floor washing machine to solve the above problems. Summary of the Utility Model
[0005] In order to overcome the above deficiencies in the existing technology, the purpose of the utility model is to provide a sewage tank structure for a floor washing machine.
[0006] To achieve the above purpose and other related purposes, the technical solution provided by the utility model is: a sewage tank structure for a floor washing machine, including a box body and a box cover. The box cover is sealingly connected to the top opening of the box body. An air outlet is provided on the box cover, and the air outlet extends inward to form an air outlet pipe extending into the interior of the box body.
[0007] A preferred technical solution is: a mesh cover is provided at one end of the air outlet pipe extending into the interior of the box body. The skirt of the mesh cover is sleeved on the outer periphery of the air outlet pipe and forms a step surface with the air outlet pipe.
[0008] A preferred technical solution is: a water inlet is provided at the bottom of the box body, and the water inlet extends inward to form a water inlet pipe extending into the interior of the box body.
[0009] A preferred technical solution is: a partition is provided on the bottom side of the box cover, and the partition is located between the air outlet pipe and the water inlet pipe.
[0010] A preferred technical solution is: sealing strips for sealing connection with the inner wall of the box body are provided on both sides of the partition.
[0011] The preferred technical solution is that: an electrode liquid level detection device for detecting the sewage liquid level in the box body is further provided on the partition board.
[0012] Due to the application of the above technical solution, the beneficial effects of the present utility model are as follows:
[0013] A sewage tank structure for a floor washer proposed by the present utility model extends the air outlet inward to form an air outlet pipe extending into the interior of the box body. In this way, when the sewage submerges the inner side of the box cover, the pipe wall of the air outlet pipe extends the water flow path, and this structure can improve the problem of easy backflow of sewage caused by arranging the air outlet at the bottom side of the box cover.

[0020] Embodiment:
[0021] As Figures 1 to 3 shown, according to a general technical concept of the present utility model, a sewage tank structure for a floor washer is provided, which includes a box body 1 and a box cover 2. The box cover 2 is sealingly connected to the top opening of the box body 1. An air outlet is provided on the box cover 2, and the air outlet extends inward to form an air outlet pipe 21 extending into the interior of the box body 1. In this solution, the air outlet is extended inward to form the air outlet pipe 21 extending into the interior of the box body 1, and the sewage needs to pass through the pipe wall of the air outlet pipe 21 to enter the suction source. Thus, when the floor washer is used lying flat, if the sewage submerges the inner side of the box cover 2, there will be no problem of sewage backflow caused by directly setting the water outlet on the box cover 2.
[0022] As Figures 1 to 3 shown, in an exemplary embodiment of the present utility model, a mesh cover 3 is provided at one end of the air outlet pipe 21 extending into the interior of the box body 1. The skirt of the mesh cover 3 is sleeved on the outer periphery of the air outlet pipe 21 and forms a step surface 31 with the air outlet pipe 21. The setting of the mesh cover 3 can reduce the kinetic energy of the surge and prevent a large amount of sewage from entering the suction source. The step surface 31 is equivalent to increasing the water flow path and further reducing the possibility of sewage backflow.
[0023] As Figures 1 to 3 shown, in an exemplary embodiment of the present utility model, a water inlet is provided at the bottom of the box body 1, and the water inlet extends inward to form a water inlet pipe 11 extending into the interior of the box body 1, which is used to increase the liquid inlet height of the sewage and avoid increasing the burden on the suction source due to the need to overcome the pressure caused by sewage backflow during the suction process due to too low liquid inlet height.
[0024] As Figures 1 to 3 shown, in an exemplary embodiment of the present utility model, a partition 22 is provided on the bottom side of the box cover 2. The partition 22 is located between the air outlet pipe 21 and the water inlet pipe 11, which can prevent sewage from being directly sucked into the air outlet pipe 21 when it is discharged from the water inlet pipe 11.
[0025] As Figures 1 to 3As shown, in an exemplary embodiment of the present utility model, sealing strips 4 for sealing connection with the inner wall of the box body 1 are provided on both sides of the partition plate 22 to form a sealed U-shaped channel for extending the airflow path and preventing sewage from being directly sucked by the air outlet pipe 21 after entering the box body 1 from the water inlet pipe 11.
[0026] As Figures 1 to 3 shown, in an exemplary embodiment of the present utility model, an electrode liquid level detection device 5 for detecting the liquid level of sewage in the box body 1 is further provided on the partition plate 22 to detect the liquid level height of the sewage and prevent excessive sewage from being sucked in.
[0027] Therefore, the present utility model has the following advantages:
[0028] A sewage tank structure for a floor washer proposed by the present utility model extends the air outlet inward to form an air outlet pipe extending into the box body. In this way, when the sewage submerges the inner side of the box cover, the pipe wall of the air outlet pipe extends the water flow path, and this structure can improve the problem of easy backflow of sewage caused by setting the air outlet at the bottom side of the box cover.
[0029] The above embodiments are only illustrative of the principles and effects of the present utility model and are not intended to limit the present utility model. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present utility model. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present utility model should still be covered by the claims of the present utility model.
