Technical Field

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

[0002] With the development of society, people's requirements for environmental hygiene are getting higher and higher. Floor scrubbers have been widely used as an important floor cleaning equipment. Floor scrubbers are equipped with sewage tanks, which can suck sewage from the cleaning area into the liquid storage chamber to complete the cleaning work.

[0003] The shape of the sewage tank of the floor scrubbers on the market is no longer restricted to a circular shape. In order to obtain a lighter weight and a smaller volume, the sewage tank is usually of a special-shaped structure, which results in a concave structural feature in the sealing cross-sectional profile. Since the seal is affected by the pre-tensioning force, the seal will separate from the concave feature of the sealing cross-sectional profile, resulting in leakage. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a sealing assembly, a sewage tank and a cleaning device, which can enable the seal to open outward and leave the sealed component at the concave characteristic position of the sealing cross-section without being affected by tension, thereby solving the problem of leakage caused by separation of the seal and the sealed component at the concave characteristic position of the sealing cross-section in ordinary sealing structures.

[0014] Furthermore, the thickness of the positioning block is consistent with the thickness of the inner side wall.

[0015] Furthermore, an outer side wall forming the groove is in contact with the second connecting member.

[0016] Furthermore, when the first connecting member or the second connecting member is installed on the second connecting member or the first connecting member from top to bottom, the outer wall of the seal is pushed upward by the second connecting member or the first connecting member, and the opening of the notch is set toward the first connecting member or the second connecting member, thereby preventing the seal from being deformed or detached from the sealing groove during installation.

[0017] Furthermore, the non-concave portion is convex.

[0018] Furthermore, the sealing member comprises a concave portion and a non-concave portion connected together.

[0022] Compared with the prior art, the advantages of the present invention are:

[0023] 1. By providing a notch at the connection between the concave portion and the non-concave portion in the seal, when the seal is assembled into the sealing groove, the seal will be stretched open by the first connecting member and stress will be generated. The notch can make the concave portion of the seal no longer open outward and leave the first connecting member under the influence of tension, thereby achieving the purpose of improving the sealing effect and avoiding leakage.

[0024] 2. By arranging a positioning block at the position corresponding to the notch, the positioning block is matched with the notch to prevent the concave portion of the seal from being affected by tension, causing the entire seal to slide toward the non-concave portion and thus causing the concave portion of the seal to leave the surface of the first connecting member, thereby further ensuring the sealing effect of the seal.
