Description

Technical Field

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

[0002] Dust mites are microorganisms that are difficult to detect with the naked eye and are widely present in our daily lives. Their body size is typically about 0.5 millimeters, with some species as small as 0.1 millimeters. Dust mites pose a significant threat; their corpses, secretions, and excrement can all be allergens. Therefore, mite-removal brushes are commonly used to eliminate dust mites from the environment. Current mite-removal brushes generally connect to a vacuum cleaner, and the vacuum cleaner's suction power draws dust mites and other debris into the vacuum cleaner. The limitation of this method is that the suction power cannot be adjusted, resulting in poor mite-removal effectiveness. Utility Model Content

[0003] The purpose of this invention is to provide a rotatable mite-removing brush head. This rotatable mite-removing brush head not only allows users to rotate the sleeve to adapt to various usage scenarios, but also limits the rotation of the sleeve to an appropriate range. Furthermore, it allows for adjustment of the actual air inlet size and suction power, thereby improving the cleaning and dust removal effect.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a rotatable mite-removing brush head, comprising: a housing with a mounting cavity at the bottom; a suction pipe, a roller brush, and a drive assembly connected to the mounting cavity via an air inlet located at the upper part of the housing; a sleeve disposed within the mounting cavity, the inner wall of which is set as an arc-shaped surface; the roller brush being rotatably disposed within the sleeve; the upper and lower parts of the sleeve, which is rotatable relative to the housing, are respectively provided with an upper opening and a lower opening 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; the lower opening is a strip-shaped opening extending along the length direction of the roller brush; at least one long side of the lower opening has a horizontally outwardly extending flange strip at its edge; the lower surface of the flange strip, which rotates with the sleeve, is used to contact the surface to be cleaned; at least one flange strip has a bent portion extending towards the housing in its middle region; and a stop groove is provided on the housing to cooperate with the bent portion.

[0005] The following are further improvements to the above technical solution:

[0006] 1. In the above scheme, the upper opening is an oblong hole, the minor diameter of which is the same as the inner diameter of the circular air inlet, and the major diameter is greater than the inner diameter of the air inlet.

[0007] 2. In the above scheme, flange strips are provided at the edges of the four sides of the lower opening of the sleeve.

[0008] 3. In the above scheme, the outer wall of the sleeve and the inner wall of the shell are connected by at least one set of circumferentially extending guide strips and guide grooves.

[0009] 4. In the above scheme, the flange strip, the bending part and the sleeve are integrally formed structures.

[0010] 5. In the above scheme, the drive component is installed in the housing through a support frame and is connected to one end of the roller brush in a transmission manner.

[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 rotatable mite-removing brush head. A sleeve is housed within a mounting cavity with an arc-shaped inner wall. The 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, each 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. The lower opening is a strip-shaped opening extending along the length of the roller brush. At least one long side of the lower opening has a horizontally outwardly extending flange. The lower surface of the flange, which rotates with the sleeve, is used to contact the surface to be cleaned. The sleeve has a bend extending towards the housing in the middle area of ​​at least one flanged strip. A stop groove that mates with the bend is provided on the housing. This allows the user to rotate the sleeve to adapt to various usage scenarios, limits the rotation of the sleeve to an appropriate range, and allows adjustment of the overlapping area between the upper opening and the air inlet by rotating the sleeve. This enables adjustment of the actual air inlet size and suction power to meet different usage scenarios, and keeps the lower opening and the surface to be cleaned in a horizontal fit, improving cleaning and dust removal efficiency.
