Description

Technical Field

[0001] The invention relates to the field of vacuum cleaners, and in particular to a vacuum cleaner roller brush structure and a vacuum cleaner that is easy to disassemble. Background Art

[0002] Vacuum cleaners are cleaning devices widely used in advanced human life and industrial production. They have been developed for more than 100 years. The working principle of vacuum cleaners is to use the motor to drive the blades to rotate at high speed, generate negative air pressure in the sealed shell, and then absorb dust through the external suction pipe.

[0003] In current vacuum cleaners, the roller brush part is connected to the suction pipe as the main cleaning component. The current roller brush mechanism mainly consists of a roller brush housing and a roller brush. The end of the roller brush is usually connected to the housing by a block, which is convenient for disassembly and assembly, but it is easy to cause damage to the end of the roller brush and the block, and the service life is not long. In addition, sometimes the user needs to use a lot of strength to disassemble and assemble the roller brush, which is not very convenient in use. Summary of the invention

[0024] A vacuum cleaner provided in a first embodiment of the present invention comprises a vacuum cleaner main body, and also comprises the above-mentioned vacuum cleaner roller brush structure that is easy to disassemble.

[0025] The present embodiment provides a vacuum cleaner roller brush structure and a vacuum cleaner that are easy to disassemble. When installing the roller brush, the first end of the roller brush presses the inclined surface of the disassembly push plate, i.e., the reset plate, to cause the disassembly push plate to shift until the roller brush is installed in place. The disassembly push plate returns to its original position due to the action of the reset plate, and the roller brush is thereby fixed in the roller brush housing. When taking out the roller brush, the reset plate of the disassembly push plate is pushed, and then the roller brush will be popped out, and then the disassembly push plate returns to its original position. Through the arrangement of the above-mentioned structure, the traditional card block connection structure can be replaced, the problem of easy damage and short life of the card block can be solved, and disassembly and assembly are more convenient.

[0026] Embodiment 2:

[0027] See also Figures 1 to 4 The figure shows a vacuum cleaner roller brush structure and a vacuum cleaner that are easy to disassemble provided by embodiment 2 of the present invention. This embodiment further makes the following improved technical solutions on the basis of the above embodiments: the disassembly push plate 23 is a rectangular plate as a whole, and is provided with a fourth end 234 opposite to the third end 231. The fourth end 234 contacts or is connected to the first end 21, so as to achieve a stable fit with the roller brush.

[0028] In order to ensure further stable cooperation with the roller brush, a triangular boss 235 is provided at the bottom of the fourth end 234. The triangular boss 235 contacts or connects the first end 21. The triangular boss can be a right-angled triangular boss.

[0029] Embodiment three:

[0030] See also Figures 1 to 4 , the figure shows a vacuum cleaner roller brush structure and a vacuum cleaner that are easy to disassemble provided by the third embodiment of the present invention. This embodiment further makes the following technical solutions as improvements on the basis of the above embodiments: a first rectangular hole 236 is opened on the disassembly push plate 23, and a convex rib 237 is arranged on the edge of the hole of the first rectangular hole 236. Through the arrangement of the above structure, on the one hand, the overall weight of the disassembly push plate can be reduced, and on the other hand, the design of the rectangular hole can be used to realize the deformable characteristics of the disassembly push plate, which is conducive to the roller brush to push the disassembly push plate, forming a greater ejection force for the roller brush to eject.

[0031] Embodiment 4:

[0032] See also Figures 1 to 4 The figure shows a vacuum cleaner roller brush structure and a vacuum cleaner that are easy to disassemble provided by embodiment 4 of the present invention. This embodiment further makes the following improved technical solutions on the basis of the above embodiments: a second rectangular hole 238 is opened on the reset plate 232, which can be used as a connecting hole with the tension spring on the one hand, and can also facilitate the deformation of the reset plate, which is conducive to pushing the reset plate and forming a greater ejection force for the roller brush.

[0033] Embodiment five:

[0034] See also Figures 1 to 4 , the figure shows a vacuum cleaner roller brush structure and a vacuum cleaner that are easy to disassemble provided by the fifth embodiment of the present invention. This embodiment further makes the following technical solutions as improvements on the basis of the above embodiments: an arc-shaped end surface 239 is provided on the free end of the reset plate 232; a plurality of triangular convex ribs 240 are provided at the connection between the reset plate 232 and the disassembly push plate 23. Through the arrangement of the above structure, a more stable connection structure between the reset plate and the disassembly push plate can be achieved.

[0035] Embodiment six:

[0036] See also Figures 1 to 4, the figure shows a vacuum cleaner roller brush structure and a vacuum cleaner that are easy to disassemble provided by the sixth embodiment of the present invention. This embodiment further makes the following technical solutions as improvements on the basis of the above embodiments: a shock absorbing component 3 is arranged on the first end 21, and the shock absorbing component 3 includes a shock absorbing seat 31, and a shock absorbing block 32 is installed in the shock absorbing seat 31, and the shock absorbing block 32 is connected to the inner wall of the shock absorbing seat 31 through a spring 33. Through the arrangement of the above structure, the combination of the spring and the tension spring makes the roller brush feel better when disassembling, and the shock absorbing block assembly controls the disassembly and shock absorbing limit of the roller brush. The mutual cooperation of the two parts makes the installation and disassembly of the roller brush simple and smooth, and more convenient for users to use.

[0037] Continue to see Figures 1 to 4 The surface of the shock absorbing seat 31 is provided with a step surface 34, which is in a concave arc shape, so that the bottom weight of the shock absorbing seat is lighter than the top, so that the shock absorbing seat can push the roller brush by the top of the roller brush, so that the roller brush pops up at an angle, and the pop-up opening is larger, which is convenient for disassembly.

[0038] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
