Description

Technical Field

[0001] The utility model relates to the technical field of vacuum cleaner floor brushes, in particular to a floating comb tooth structure of a vacuum cleaner floor brush. Background Art

[0002] Cleaning equipment such as vacuum cleaners and floor scrubbers use rolling floor brushes to clean the dirt and dust on the ground. For example, Chinese patent CN221430951U discloses a floor brush assembly disassembly structure and a cleaning device thereof. The floor brush assembly disassembly structure includes a housing, a rotating assembly, a floor brush assembly, and a locking assembly. The housing has a first mounting cavity, the rotating assembly is installed in the first mounting cavity and connected to the housing, the floor brush assembly is installed in the first mounting cavity, one end of the floor brush assembly is connected to the rotating assembly, and is rotatably connected to the housing through the rotating assembly, the locking assembly is connected to the housing, and is configured to be connected or disconnected from one end of the floor brush assembly away from the rotating assembly in response to external pressure. In this solution, the floor brush assembly can rotate around the rotating assembly, and then be pulled out and disassembled after the rotation is completed, avoiding contact, interference and friction with the ground and other components in the housing, facilitating the disassembly of the floor brush assembly, and the floor brush assembly can be rotated to an angle where the user can easily exert force, making it more convenient to dismantle the floor brush assembly.

[0003] During the cleaning process of the floor brush, the roller brush rotates to clean the floor, so hair is easily entangled on the roller brush, affecting the rotation of the roller brush. In order to prevent the hair from entangled with the roller brush, the floor brush usually uses a comb tooth structure to comb and scrape the bristles on the roller brush when the roller brush rotates, so as to separate the hair from the roller brush. For example, Chinese patent CN221285639U discloses a surface cleaning device that can prevent hair from entanglement, including a floor brush, a roller brush and a combing member with comb teeth, the comb teeth have a front tooth surface facing the roller brush and a lower tooth surface away from the roller brush, the tooth tips of the comb teeth extend into the bristles of the roller brush to prevent the hair from entangled with the roller brush, and the lower tooth surface is provided with a stop groove, and the stop groove is arranged near the tooth tip to hook and block the hair. The structure of the comb teeth is improved, and the stop groove is used to hook and block the long hair stripped off by the tooth tip, so as to prevent the stripped long hair from being re-entangled on the roller brush, thereby improving the stripping effect of the combing member on the hair, thereby improving the cleaning effect of the roller brush on the surface to be cleaned.

[0004] The existing comb tooth structure in the floor brush needs to maintain contact with the roller brush during its rotation, causing the scraper strips on the roller brush to hit the comb teeth during rotation, which in turn causes problems such as high noise and high operating current during the operation of the floor brush, resulting in a large load and high energy consumption during operation of the floor brush. Utility Model Content

[0005] The utility model aims to provide a floating comb tooth structure of a floor brush of a vacuum cleaner, so as to solve the problems of heavy load and loud noise during the operation of the floor brush caused by the existing fixed comb tooth structure in the floor brush.

[0006] To achieve the above object, the present utility model adopts the following technical solutions: A floating comb tooth structure for a vacuum cleaner floor brush, comprising:

[0007] A floor brush housing, inside which a rotatable roller brush is provided;

[0008] A comb tooth fixing seat, which is fixedly installed inside the floor brush housing;

[0009] A comb tooth bar, which is elastically connected inside the comb tooth fixing seat, and the comb teeth of the comb tooth bar face the roller brush;

[0010] A push button, which is fixedly installed at the end of the comb tooth bar, and the comb tooth bar passes through the floor brush housing and then connects to the push button.

[0011] As a further description of the above technical solution:

[0012] The floor brush housing includes a lower cover plate, an upper cover plate and a transparent cover. The transparent cover is detachably installed on the lower cover plate, the upper cover plate is fixedly installed on the lower cover plate, and the end of the comb tooth bar passes through the transparent cover and the upper cover plate in sequence and then connects to the push button.

[0013] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present utility model are:

[0014] 1. In the present utility model, the comb tooth bar on the vacuum cleaner floor brush adopts a floating design. When hair removal is required, cleaning is achieved by manually pushing the comb tooth bar. In the normal operating state of the floor brush, the comb tooth bar is separated from the roller brush to achieve clearance, avoiding affecting the rotation of the roller brush, so that the floor brush has a small load and low noise during operation.

[0015] 2. In the present utility model, the setting of the transparent cover on the floor brush housing enables the rotation cleaning process of the roller brush to be clearly observed. When hair entanglement appears on the roller brush, it can be discovered in time, and then the comb tooth bar can be pushed towards the roller brush through the push button. The comb teeth of the comb tooth bar contact the surface of the roller brush 11, so that the hair can be effectively removed.

[0016] 3. In the present utility model, during the process of pushing the push button, the sliding direction and stroke of the push button are restricted by the groove and the strip-shaped hole on the bottom surface of the groove, so as to effectively control the contact distance between the comb tooth bar and the roller brush, thereby avoiding the large load and high noise of the floor brush caused by the comb tooth bar.
