Description

Technical Field

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

[0002] Cleaning equipment such as vacuum cleaners absorb garbage or dust in the environment through vacuum. They are easy to use and light, so they are popular among users. For example, in traditional cleaning equipment, such as vacuum cleaners, dust is stored in a dust cup, and the dust cup has a dust discharge port, which is usually sealed with a sealing cover. Traditional sealing covers have poor sealing effects on the dust discharge port, and dust is easy to leak through the gap between the sealing cover and the dust cup.

[0003] Therefore, in view of the shortcomings of the prior art, it is necessary to design a sealing cover structure used in the dust cup to solve the above problems. Utility Model Content

[0004] In order to overcome the above-mentioned deficiencies in the prior art, the utility model aims to provide a sealing cover structure used in a dust cup.

[0006] The preferred technical solution is: the upper lip is constructed as an L-shaped structure and includes a horizontal section and a vertical section, the horizontal section covers the top side groove wall of the annular groove, the vertical section covers the notch corresponding to the top side groove wall of the annular groove, and the outer wall of the vertical section is fitted between the inner wall of the dust cup body.

[0007] The preferred technical solution is that the outer ring of the lower lip is arranged to fit in correspondence with the edge of the dust discharge port.

[0008] The preferred technical solution is: one side of the sealing cover is hinged to the dust exhaust port, and the other side of the sealing cover is buckled to the dust exhaust port.

[0009] The preferred technical solution is: the sealing ring is made of rubber material.

[0010] Due to the application of the above technical solution, the utility model has the following beneficial effects:

[0011] The sealing cover structure used in the dust cup provided by the utility model completely blocks the gap between the sealing cover and the dust cup body by setting the upper lip of the sealing ring to cover the top groove wall of the annular groove and extending the end thereof to the corresponding groove opening, thereby preventing dust from leaking out through the gap. The utility model has the characteristics of simple structure and good sealing effect, and is suitable for popularization and use. BRIEF DESCRIPTION OF THE DRAWINGS
