Description

Technical Field

[0001] This utility model relates to the field of cleaning tools, and in particular to a mite-removing vacuuming mechanism. Background Technology

[0002] Vacuum cleaners hold an irreplaceable position in modern home life. As a primary tool for indoor cleaning, vacuum cleaners come in various types. With product upgrades and increasingly higher consumer demands, some vacuum cleaners now come equipped with mite-removal brushes, achieving both cleaning and mite removal. Currently, vacuum cleaners with mite-removal brushes include the vacuum cleaner body and the brush connected to it. Compared to other mite-removal devices, mite-removal brushes are more suitable for daily use, especially for cleaning sofas, blankets, and furniture such as beds and cabinets. Since the targets for mite removal are generally soft surfaces like bedding and sofas, existing mite-removal brushes can easily experience issues such as excessive suction causing the brush head to become stuck, or insufficient suction resulting in poor mite removal. Utility Model Content

[0003] The purpose of this utility model is to provide a mite-removing vacuuming mechanism that allows for adjustment of the actual air inlet size and suction power, thereby improving the cleaning and vacuuming effect. It also enhances the smoothness and stability of the rotation process and effectively avoids the situation where the elastic layer thickens due to the filling of fine particles during long-term use, thus hindering the rotation of the sleeve.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a mite-removing vacuuming mechanism, comprising: a housing with an installation cavity at the bottom, an inner suction pipe communicating with the installation cavity through an air inlet opened at the upper part of the housing, a roller brush, a drive assembly, and an air guide pipe for connecting with the vacuuming body. An outer sleeve is provided on the outside of the inner suction pipe. In addition, a first connecting pipe is sealed and connected inside the outer sleeve at the end of the inner suction pipe away from the air inlet. The other end of the air guide pipe, one end of which is connected to the vacuuming body, is connected to a second connecting pipe that is inserted into and cooperates with the first connecting pipe. The end of the second connecting pipe opposite to the air guide pipe can be inserted into the outer sleeve.

[0005] A sleeve is installed inside the mounting cavity, which has an arc-shaped inner wall. The roller brush is rotatably installed inside the sleeve. The upper and lower parts of the sleeve, which can rotate relative to the housing, are respectively provided with an upper opening and a lower opening that communicate with the inside of the sleeve. The inner diameter of the upper opening, which corresponds to the air inlet, is greater than or equal to the inner diameter of the air inlet. Two baffles extending in the circumferential direction are provided on the arc-shaped inner wall of the housing mounting cavity. An elastic layer is provided between the two baffles that are spaced apart on both sides of the air inlet. One surface of the elastic layer, which is located between the housing and the sleeve, is in contact with the housing. A plastic pad is provided between the other surface of the elastic layer and the sleeve. This plastic pad is in contact with the elastic layer.

[0006] The following are further improvements to the above technical solution:

[0007] 1. In the above scheme, the elastic layer is a foam layer and the plastic pad layer is a PET pad layer.

[0008] 2. In the above scheme, the elastic layer is bonded to the inner wall of the sleeve and the plastic pad layer.

[0009] 3. In the above scheme, both the elastic layer and the plastic pad layer are provided with clearance holes corresponding to the air inlet.

[0010] 4. In the above scheme, a sealing ring is provided between the inner suction tube and the first connecting tube, and between the first connecting tube and the second connecting tube.

[0011] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0012] This utility model relates to a mite-removing vacuum cleaner mechanism. An outer sleeve is provided outside the inner suction tube. A first connecting tube is sealed and connected to the end of the inner suction tube furthest from the air inlet within the outer sleeve. A second connecting tube, which is inserted into the first connecting tube, is connected to the other end of a duct connected to the vacuum cleaner body. The end of the second connecting tube opposite to the duct can be inserted into the outer sleeve. A sleeve is housed within a mounting cavity with an arc-shaped inner wall. A roller brush is rotatably mounted within this sleeve. The upper and lower parts of the sleeve, which can rotate relative to the housing, have upper and lower openings respectively communicating with the interior of the sleeve. The inner diameter of the upper opening, corresponding to the air inlet, is greater than or equal to the inner diameter of the air inlet. Two baffles extending circumferentially are provided on the arc-shaped inner wall of the mounting cavity, spaced apart between the two baffles on either side of the air inlet. An elastic layer is provided, with one surface of the elastic layer attached to the shell and the sleeve, and a plastic pad layer between the other surface of the elastic layer and the sleeve. This plastic pad layer is attached to the elastic layer. In addition to mite removal and dust removal, the overlapping area between the upper opening and the air inlet can be adjusted by rotating the sleeve, thereby adjusting the actual air inlet size and suction power to meet different usage scenarios. It can also keep the lower opening and the surface to be cleaned in a horizontal fit, improving the cleaning and dust removal effect. It can also improve the smoothness and stability of the sleeve during rotation and ensure the stability of the sleeve when not rotating, avoiding unnecessary rotation of the sleeve that interferes with the cleaning process. It can also effectively prevent the elastic layer from thickening due to fine particles filling the sleeve during long-term use, which would hinder the rotation of the sleeve.
