Description

Sealing structure of cleaning equipment and cleaning equipment Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, in particular to a sealing structure of cleaning equipment and the cleaning equipment. Background Art

[0002] Currently, commercially available cleaning equipment, such as floor brushes, typically have separate sewage tanks and main units to facilitate cleaning. To ensure a tight seal between the tank and main unit, a sealing ring is typically installed on the tank to seal the connection between the two. The sealing contact surfaces of existing sealing rings are coplanar, extending outward from the first plane of the air inlet. During installation, the front sealing edge of the tank can rub against the air inlet, causing it to buckle. This can prevent the gap between the tank and main unit from being completely sealed, leading to air leakage and impacting product performance.

[0003] In order to solve the problem that the front end of the sealing ring causes leakage due to friction, thereby affecting the sealing effect, a Chinese utility model patent with patent publication number CN111358344A discloses a recycling barrel, comprising a barrel body and a sealing ring, wherein the barrel body is provided with an air outlet, and the sealing ring is arranged around the outer periphery of the air outlet, wherein, along the assembly direction of the barrel body, a second flange and a first flange are respectively provided on the front and rear of the sealing ring, and the extension direction of the first flange and the second flange is opposite to the assembly direction, the first flange extends in a direction away from the central axis of the sealing ring, and the second flange extends in a direction toward the central axis of the sealing ring. The extension direction of the first flange and the second flange of the sealing ring of the prior art is opposite to the assembly direction. Therefore, when assembling along the assembly direction, even if the first flange and the second flange rub against the first plane of the air inlet, the sealing edge will not be flanged, thereby avoiding air leakage caused by the flange of the sealing ring. However, this existing technology still has structural defects, that is, the first flange and the second flange surface of the sealing ring are on the same plane. When assembling along the assembly direction, the second flange always rubs against the first plane of the air inlet, causing certain wear on the second flange, shortening the service life of the sealing ring, and even causing the sealing ring to tear.

[0004] Therefore, there is still room for improvement in the prior art. Technical Solutions

[0005] In response to the defects in the prior art, the present invention provides a sealing structure of a cleaning device and a cleaning device. The sewage tank assembly of the present invention is installed on the main body of the cleaning device. Since the second plane of the sealing ring is set lower than the first plane of the sealing ring, and the second plane of the sealing ring is located at the front end of the opening of the sewage tank, when the sewage tank is installed, the second plane of the sealing ring will not generate contact friction with the first plane of the air inlet of the air inlet on the main body, so there will be no flanging of the sealing ring and no wear and tear.

[0006] In order to achieve the above-mentioned purpose, the technical solution applied by the present utility model is as follows:

When the sewage tank of the utility model is mounted on the equipment body, since the first sealing surface of the sealing ring is located lower than the second sealing surface, the first sealing surface will not contact or rub against the first sealing contact surface regardless of whether the sewage tank is pushed in or opened, and the second sealing surface will only seal against the first sealing contact surface after the sewage tank is fully pushed in. When the sewage tank is pulled out, the first sealing surface will not contact or rub against the first sealing contact surface. Therefore, the sealing ring will not be subjected to flanged edges or wear and tear during the entire process, effectively solving the problems existing in the prior art.

[0008] According to the above solution, the device body is provided with a second sealing contact surface, the first sealing contact surface and the second sealing contact surface are arranged at an angle, and a third sealing surface is provided on the outer side of the first sealing surface.
