Description

Technical Field

[0001] This utility model relates to the field of floor scrubbing machine technology, and in particular to a floor scrubbing machine. Background Technology

[0002] Existing floor scrubbers typically include a handle and a floor brush. The floor brush performs wet mopping and has a wastewater tank.

[0024] Reference Figure 1-3 A floor scrubbing machine includes a floor brush, which comprises a housing 100 and a wastewater tank 200. The housing 100 has a suction port and a suction channel 120. The suction port is located at the front of the housing 100, and the suction channel 120 is located on the right side of the housing 100. The wastewater tank 200 is installed at the rear of the housing 100. The right end of the wastewater tank 200 has a water inlet 210. The water inlet end of the suction channel 120 is connected to the suction port, and the water outlet end of the suction channel 120 is connected to the water inlet 210. The wastewater tank 200 has a water-blocking rib 220 inside, which is located at the top of the wastewater tank 200. The water-blocking rib 220 and the upper wall of the wastewater tank 200 form a water inlet channel 221. The water inlet end of the water inlet channel 221 is connected to the water inlet 210, and the water outlet end of the water inlet channel 221 extends to the left side of the wastewater tank 200 and communicates with the internal space of the wastewater tank 200.

[0025] This utility model uses a water-blocking rib 220 to surround the water inlet 210, forming a long strip-shaped water inlet channel 221. It changes the position of the water outlet of the water inlet 210, and directs the water outlet of the water inlet 210 from the right side to the left side of the sewage tank 200. After the sewage enters from the water inlet 210, it needs to flow into the sewage tank 200 from the left side of the top of the sewage tank 200 through the water inlet channel 221, which reduces the situation where water in the sewage tank 200 flows out of the water inlet 210 when the floor brush is tilted.

[0026] In some embodiments of this invention, the ratio of the lateral length L1 of the water inlet channel 221 to the lateral length L2 inside the sewage tank 200, L1 / L2, is ≥3 / 4. The water inlet channel 221 is long enough to ensure that there is no leakage even when the floor brush is tilted at a large angle.

[0027] In some embodiments of this utility model, the sewage tank 200 is detachable from the housing 100. The housing 100 has a receiving cavity with an opening on the left side. The sewage tank 200 can be inserted into the receiving cavity through the opening. The sewage tank 200 is a side-pull type, which makes it convenient for users to remove the sewage tank 200 to empty the sewage. Both removal and installation are relatively convenient.

[0028] In some embodiments of this invention, a sealing gasket 300 is provided at the water inlet 210, and the water inlet 210 forms a sealed connection with the water outlet of the suction channel 120 through the sealing gasket 300. The sealing gasket 300 forms an airtight seal at the connection of the water inlet 210, ensuring that negative pressure is generated within the suction channel 120. The sealing gasket 300 also prevents the possibility of sewage seeping or dripping at the interface, avoiding soiling the inside of the machine.

[0029] In some embodiments of this utility model, a water inlet cavity 230 is formed inside the sewage tank 200, and the water inlet 210 is located on the right side of the water inlet cavity 230. The bottom of the water inlet cavity 230 is connected to the water inlet end of the water inlet channel 221. A piston 400 and a spring 500 are provided inside the water inlet cavity 230. The piston 400 can move in the left and right direction to open or block the water inlet 210. The spring 500 is used to provide a rightward elastic force to the piston 400. The water outlet end of the sewage suction channel 120 is provided with a top pressure rib 121. The top pressure rib 121 is opposite to the piston 400. When the sewage tank 200 is inserted into the receiving cavity, the top pressure rib 121 can push the piston 400 to open the water inlet 210. With the wastewater tank 200 disassembled, the rightward force of the spring 500 presses the piston 400 firmly against the inlet 210, forming a physical seal and preventing communication between the inside of the wastewater tank 200 and the outside. This ensures that wastewater inside the tank will not leak out of the inlet 210 when the user removes the tank for emptying. With the wastewater tank 200 installed, the top pressure rib 121 presses against the piston 400 (overcoming the spring force of the spring 500), pushing the piston 400 to the left, thereby opening the inlet 210. At this time, the suction channel 120 and the water inlet channel 221 are fully connected, allowing the floor scrubber to operate normally and wastewater to be smoothly sucked in.

[0030] In some embodiments of this utility model, the left wall of the water inlet chamber 230 is provided with a mounting post 231, the piston 400 is provided with a limiting groove 410, one end of the spring 500 is sleeved on the mounting post 231, and the other end extends into the limiting groove 410. The combined structure of the mounting post 231 and the limiting groove 410 guides and restricts the piston 400 to move only along a preset left and right straight path.

[0031] In some embodiments of this utility model, a clean water tank 600 is also included, which is an integral structure with the wastewater tank 200. The integrated tank structure allows the clean water tank 600 and the wastewater tank 200 to be pulled out at once, so that the user can complete the function that existing floor scrubbers require two separate actions to empty the wastewater and refill the clean water by simply removing and placing the tank once.

[0032] In some embodiments of this utility model, the clean water tank 600 is located above the wastewater tank 200. The clean water tank 600 and the wastewater tank 200 are stacked vertically, and the water inlet chamber 230 can occupy the right side space of the clean water tank 600, making the overall structure compact.

[0033] In some embodiments of this utility model, the sewage tank 200 is provided with an outlet 240 at its left end, and a sealing cap 250 is provided on the top of the outlet 240. The water in the sewage tank 200 can be poured out through the outlet 240, or clean water can be poured in through the outlet 240 to clean the inside of the sewage tank 200.

[0034] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
