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] A floor scrubber typically consists of the scrubber body and a base station. The base station charges the scrubber body and performs self-cleaning. After the scrubber finishes its work, it needs to be placed on the base station. Current technology uses an outward-folding sealing cover at the drain outlet of the wastewater tank. A motor drives the cover to open, allowing wastewater to drain out. However, this structure is not only complex but also slow in opening and closing the drain outlet. If the user lifts the scrubber while the cover is closing, all the water in the tank will leak onto the base station. Utility Model Content

[0027] Reference Figure 1-5 A floor scrubbing machine includes a body 100 and a base station 200. The body 100 is equipped with a wastewater tank 110. The bottom wall of the wastewater tank 110 has a drain outlet 111. A sealing component is provided at the drain outlet 111. The sealing component includes a flip cover 310 and an elastic element 320. The flip cover 310 is used to close and open the drain outlet 111. The elastic element 320 can make the flip cover 310 always tend to close the drain outlet 111. The base station 200 is equipped with a wastewater inlet 210. A pressing part 220 is fixed in the wastewater inlet 210. When the body 100 is placed in the base station 200, the pressing part 220 can press the flip cover 310, causing the flip cover 310 to flip up towards the inside of the wastewater tank 110.

[0028] In some embodiments of this invention, the flip cover 310 is located inside the sewage tank 110. When the flip cover 310 is closed, it needs to fit tightly against the edge of the drain outlet 111 to form a reliable seal. The liquid pressure inside the sewage tank 110 acts on the upper surface of the flip cover 310, which helps the flip cover 310 press against the edge of the drain outlet 111, enhancing the sealing effect.

[0029] In some embodiments of this utility model, the sealing assembly further includes a sealing ring 330. When the flip cover 310 closes the sewage outlet, the sealing ring 330 abuts against the lower end face of the flip cover 310 and the bottom wall of the sewage tank 110, and the sealing ring 330 is arranged around the outer periphery of the sewage outlet 111. Even if the flip cover 310 is precisely manufactured, there may still be tiny unevenness or gaps caused by manufacturing tolerances between the hard contact surfaces of the metal or plastic flip cover 310 and the edge of the sewage outlet 111. As an elastic material (such as silicone or rubber), the sealing ring 330 can fill these microscopic gaps, forming a more effective physical barrier, which greatly reduces the possibility of sewage slowly seeping out from the gaps.

[0030] In some embodiments of this utility model, the sealing ring 330 is fixed to the lower end face of the flip cover 310. When the flip cover 310 is opened and closed, the sealing ring 330 moves as a whole with the flip cover 310, ensuring that its contact / separation with the edge of the drain port 111 is completely synchronized, avoiding frictional wear or deformation of the sealing ring 330 caused by the relative displacement between the sealing ring 330 and the flip cover 310.

[0031] In some embodiments of this utility model, the elastic element 320 is a torsion spring. The flip cover 310 is rotatably connected to the sewage tank 110 via a rotating shaft 340. The torsion spring is sleeved on the rotating shaft 340. One torsion arm of the torsion spring abuts against the upper end face of the flip cover 310, and the other torsion arm abuts against the inner wall of the sewage tank 110. When the torsion arm abuts against the upper end face of the flip cover 310 and the inner wall of the tank, the torsion spring always applies a torque to the flip cover 310 to make it rotate downward. As long as the body 100 is not placed in the base station 200, this torque can ensure that the flip cover 310 is stably closed.

[0032] In some embodiments of this utility model, the body 100 is provided with a sewage discharge channel 120, which is located below the sewage tank 110 and is connected to the sewage outlet 111. The top pressing part 220 is in the shape of a vertical plate and extends upward from the sewage inlet 210. When the body 100 is placed in the base station 200, the top pressing part 220 can extend into the sewage discharge channel 120 until it presses against the flip cover 310. On the one hand, the sewage discharge channel 120 has a guiding and positioning function. The top pressing part 220 can be inserted along the sewage discharge channel 120 to ensure that the sewage outlet 111 and the sewage inlet 210 are precisely connected, preventing misalignment that could cause sewage to splash out. Even if the body 100 is placed at a 30° angle, the top pressing part 220 can still slide smoothly into the sewage discharge channel 120. On the other hand, the top pressure part 220 needs to pass through a sewage channel 120 before it can act on the flip cover 310. This means that the sewage outlet 111 is concave relative to the body 100, preventing the flip cover 310 from being accidentally pushed open when mopping the floor.

[0033] In some embodiments of this utility model, the opening area of ​​the sewage inlet 210 is larger than the water outlet area of ​​the sewage discharge channel 120, and the sewage discharge channel 120 is directly opposite the sewage inlet 210, ensuring that all the sewage coming out of the sewage discharge channel 120 falls into the sewage inlet 210, and avoiding the water column hitting the edge of the sewage inlet 210 and causing sewage to splash out.

[0034] In some embodiments of this utility model, a connecting rib 211 is horizontally provided in the sewage inlet 210, and the pressing part 220 is fixed on the connecting rib 211. The connecting rib 211 is used to support the pressing part 220 and does not affect the drainage of the sewage inlet 210.

[0035] In some embodiments of this utility model, the flip cover 310 is flipped up at an angle of 60°-90° towards the inside of the sewage tank 110. Opening the flip cover 310 to a larger angle can prevent garbage from clogging the sewage outlet 111 and improve the sewage discharge speed.

[0036] In some embodiments of this invention, the top end of the pressing portion 220 has a rounded surface. Compared to right-angled edges, the rounded surface structure can reduce the coefficient of friction, thereby reducing jamming and wear on the pressing portion 220.

[0037] 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.
