[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] The present invention provides a sewage tank 100 for a cleaning device, such as Figure 1-7 As shown, the sewage tank 100 is arranged on the cleaner. Specifically, the sewage tank 100 can be installed on the cleaner by negative pressure adsorption. When the cleaner cleans the ground, the sewage tank 100 is used to collect the sewage generated by the cleaner during the cleaning process. The sewage tank 100 includes a box body 10 and a cover body 20 assembled with the box body 10, wherein a grille 30 and a connecting rod 50 are arranged in the box body 10, and the connecting rod 50 is used to connect the grille 30 and the cover body 20. The grille 30 is provided with an extension part 40 that abuts against the inner wall of the box body 10. When the cover body 20 is taken out, the extension part 40 moves along the inner wall of the box body 10 to scrape and collect the dirt attached to the inner wall of the box body 10. The grille 30 is taken out of the sewage tank 100, and the large particles of dirt attached to the grille 30 can be taken out of the sewage tank 100, and the dirt attached to the inner wall of the box body 10 is removed at the same time.

[0028] Preferably, if Figure 2-4As shown, the extension part 40 extends obliquely toward one side of the cover body 20 and forms a groove 41 with the peripheral part 32 of the grille 30. Specifically, the grille 30 is circular as a whole, and includes a grille part 31 and a peripheral part 32. The peripheral part 32 is a circular step surrounding the grille part 31; the extension part 40 extends obliquely from the bottom end of the peripheral part 32 toward the direction close to the cover body 20 and abuts against the inner wall. Preferably, the extension part 40 is a scraper bar or a cleaning brush. The scraper bar or the cleaning brush is in pressure contact with the inner wall, and the dirt on the inner wall can be scraped or brushed off. The dirt brushed off is accumulated in the groove 41 along the inclination of the extension part 40, and the dirt can be taken away from the sewage tank 100 while the cover body 20 is taken out.

[0029] Preferably, the cover body 20 includes an upper cover 21 and a lower cover 22 assembled with the upper cover 21 to form a receiving space, the receiving space accommodates the water vapor filter device 60, and the connecting rod 50 passes through the lower cover 22 and is connected to the water vapor filter device 60. Specifically, an opening 211 communicating with the cleaner is provided on the top of the cover body 20, the bottom of the upper cover 21 is in a grille shape, and the lower cover 22 is provided with a through hole for the connecting rod 50 to pass through.

[0030] Preferably, the water vapor filtering device 60 includes a water vapor compression cover 61 and a porous elastic material 62, wherein the water vapor compression cover 61 is connected to one end of the connecting rod 50 away from the grille 30, and the other end of the connecting rod 50 is connected to the grille 30. Specifically, the water vapor compression cover 61 is in a grille shape and is integrally formed with the connecting rod 50; the porous elastic material 62 is disposed between the water vapor compression cover 61 and the lower cover 22, and specifically, the porous elastic material 62 is a sponge. When the extension portion 40 moves along the inner wall of the box body 10 toward the upper cover 21, the inner wall of the box body 10 generates a downward friction force on the extension portion 40, so that the water vapor compression cover 61 applies pressure to the sponge to squeeze out the water absorbed by the sponge and flow it into the sewage tank 100. When the cover body 20 is taken out upward, the downward friction force generated by the inner wall of the box body 10 on the cleaning brush or the scraper is utilized. Since the water vapor compression cover 61 is connected to the grille 30 through the connecting rod 50, the water vapor compression cover 61 generates a downward pressure on the sponge, thereby squeezing out excess water in the sponge, so that the water content in the upper cover 21 is greatly reduced. The strong water absorption and good water removal effect of the sponge can reduce the water vapor content at the cover body 20 when the sewage tank 100 is sealed.

[0031] Preferably, a high efficiency filter 70 , namely a high efficiency air filter (HEPA) is provided between the water vapor filtering device 60 and the upper cover 21 , for capturing some particulate dust and various suspended matter.

[0032] Preferably, the sewage tank 100 is also provided with a sewage full alarm 80, which is specifically an external capacitance detection system, and two electrodes 81 are provided on opposite sides of the cylinder 12, each of which is connected to the control host of the cleaner through a conductive sheet 82, and the outer side of the electrode 81 is also covered with a plastic sheet 83. The capacitor formed by the two electrodes 81 realizes the sewage full alarm prompt function by monitoring the capacitance change caused by the water level change in the sewage tank 100.

[0033] Preferably, the box body 10 includes a bottom cover 11 opposite to the cover body 20, and a cylinder body 12 whose two ends are respectively assembled with the cover body 20 and the bottom cover 11, the bottom cover 11 is provided with a water valve 111, and a first sealing ring 13 is provided between the bottom cover 11 and the cylinder body 12 to improve the air tightness of the sewage tank 100.

[0034] The cleaner is also equipped with a storage seat 200 that matches the cleaner. The storage seat 200 is provided with a pressure rod 202 that matches the water valve 111. When the full dirt alarm 80 sounds a full dirt alarm, the cleaner stops using and can be placed on the storage seat 200. At this time, since the water valve 111 of the sewage tank 100 is relative to the pressure rod 202 of the storage seat 200, under the pressure of the pressure rod 202, the water valve 111 opens to connect the sewage tank 100 with the storage seat 200, and the sewage in the sewage tank 100 can be discharged or collected into the sewage collection tank 201 in the storage seat 200.

[0035] Specifically, the storage seat 200 is further provided with a sewage collection box 201 or a sewage discharge port. When the cleaner is stored in the storage seat 200, the sewage tank 100 and the sewage collection box 201 can be connected through the water valve 111 and the pressure rod 202 to collect sewage in the sewage collection box 201, or the sewage tank 100 discharges the sewage in the sewage tank 101 through the storage seat 200 through the water valve 111 and the sewage discharge port. The water valve 111 is a spring-type water valve 111, and the spring-type water valve includes a pressure rod 202. Sheet 1111, spring 1112 and blocking block 1113, a sealing ring is arranged between the blocking block 1113 and the bottom cover 11, the blocking block 1113 includes a blocking portion 11131 and a vertical portion 11132, the spring 1112 is sleeved on the vertical portion 11132, the pressing sheet 1111 is arranged at one end of the vertical portion 11132 away from the blocking portion 11131, when the pressure rod 202 is pressed against the pressing sheet 1111 to compress the spring, the blocking block 1113 and the pressing sheet 1111 move upward, the water valve opens, and the water valve closes when the pressure rod is withdrawn.

[0036] In summary, the present invention can conveniently and quickly remove large particle pollutants in the sewage tank and dirt adhering to the side wall of the sewage tank by means of the grille and the extension part arranged in the sewage tank, thereby reducing the burden on the user; and also by arranging a water vapor filtering device in the cover body and cooperating with the grille and the extension part, the water content at the sewage tank cover body is greatly reduced, thereby preventing secondary pollution.
