Description

Technical Field

[0001] The utility model belongs to the technical field of cleaning electrical appliances, and in particular relates to a suction-opening sewage inlet structure of a water tank. Background Art

[0002] Environmental sanitation is an important factor affecting the quality of life. Therefore, with the continuous improvement of people's requirements for quality of life, the corresponding requirements for environmental sanitation are also getting higher and higher. However, the work pressure of modern people is increasing day by day, and they are in urgent need of being liberated from the heavy cleaning work. Therefore, many ground cleaning equipment have appeared to improve environmental sanitation, and the commonly used ones are vacuum cleaners, automatic mops, sweepers and floor washers. Floor washers are a kind of equipment used to clean the ground. The current floor washers have been developed to have relatively complete functions. The working principle of the floor washers is to spray clean water or detergent from the clean water tank to the ground. After cleaning, the sewage on the ground can be sucked into the sewage tank in the floor washers again, thus completing the cleaning process.

[0003] At present, the existing sewage tank is placed on the floor brush assembly. Although it can reduce the rising height of the sewage, after the floor scrubber stops working, when the floor scrubber is moved, the sewage in the sewage tank is easy to flow out from the sewage inlet, forming stains on the ground again, affecting the user experience.

By arranging a torsion spring and a sealing cover at the sewage inlet, the suction force generated by the operation of the floor scrubber can overcome the elastic force of the torsion spring to suck up the sealing cover. When the operation stops, the sealing cover closes the sewage inlet under the action of the torsion spring to prevent sewage from flowing out.

[0005] In order to achieve the above-mentioned purpose, the utility model provides a suction-opening sewage inlet structure of a water tank, which comprises:

[0006] A floor brush, wherein a cavity is provided in the floor brush, an exhaust port and a sewage inlet are provided in the cavity, the exhaust port is connected to a floor brush hose connector, one end of the sewage inlet extends to connect to a dust suction port, and the dust suction port is located at the bottom of the floor brush;

[0007] A sealing cover, wherein a rotating shaft is arranged on one side of the sealing cover, the rotating shaft is rotatably connected to the sewage inlet, and at least one torsion spring is arranged on the rotating shaft.

[0008] As a further description of the above technical solution:

[0009] A box body is arranged in the cavity, and a box cover is arranged on the box body.

[0032] See also Figure 1-7 The utility model provides a suction-opening sewage inlet structure of a water tank, comprising:

[0033] A floor brush 1, wherein a cavity is provided in the floor brush 1, wherein an exhaust port 2 and a sewage inlet 3 are provided in the cavity, wherein the exhaust port 2 is connected to a floor brush hose connector 4, and one end of the sewage inlet 3 extends to connect to a dust suction port 5, wherein the dust suction port 5 is located at the bottom of the floor brush 1;

[0034] A sealing cover 6 is provided with a rotating shaft 7 on one side of the sealing cover 6, and the rotating shaft 7 is rotatably connected to the sewage inlet 3. At least one torsion spring 8 is provided on the rotating shaft 7. Two torsion springs are provided, which are respectively located at both ends of the rotating shaft. When the floor brush is working, the sealing cover is opened under vacuum suction, and when the floor brush is not working, the sealing cover is automatically closed under the action of the torsion spring.

[0035] In one embodiment, a box body 9 is disposed in the cavity, and a box cover 10 is disposed on the box body 9. This can improve the sealing effect of the cavity and prevent water leakage. The box cover is detachably connected to the box body, so that the box cover is easy to open to the sewage.

[0036] The box body 9 is provided with a first mounting portion 11 protruding upward at the sewage inlet 3, and the rotating shaft 7 is rotatably connected to the first mounting portion 11. The height of the sewage inlet can be increased, thereby increasing the water storage capacity of the box body, and the two free ends of the torsion spring respectively abut against the first mounting portion and the sealing cover, so as to facilitate the opening and closing of the sealing cover.

[0037] like Figure 7 The box cover 10 is provided with a support plate 12, and the bottom of the support plate 12 abuts against the second bottom surface. The support plate is a U-shaped plate structure. The support plate surrounds the remaining three sides of the first mounting portion except the side where the sealing cover is opened, so that the support strength of the box cover can be improved, and it is not easy to be flattened, and at the same time, the flip angle of the sealing cover can be limited.

[0038] Working principle: When the floor scrubber is working, the suction force generated by the floor scrubber can overcome the elastic force of the torsion spring to suck up the sealing cover, and the sewage and garbage enter from the dust suction port, and then enter the box from the sewage inlet, and the air flows out from the exhaust port. After cleaning, the floor scrubber is powered off, and the sealing cover closes the sewage inlet under the action of the torsion spring to prevent sewage from flowing out. When the box is full of sewage, the box cover can be opened to drain the sewage.

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
