Description

Technical Field

[0001] This utility model belongs to the field of vacuum cleaner technology, and in particular relates to a floor brush base structure that facilitates the disassembly and assembly of accessories. Background Technology

[0002] A vacuum cleaner is a household or commercial cleaning device primarily used to remove dust, debris, and other fine particles from areas such as floors, carpets, and furniture surfaces. It uses an electric motor to drive a fan, generating suction that draws dust and debris into a dust collection container or bag, thus maintaining a clean environment.

[0003] In the daily use of a vacuum cleaner, the spring at the connection between the floor brush base and the bottom of the handle plays a crucial role. It is responsible for cushioning and shock absorption and maintaining the flexibility of the connection to adapt to the operational needs of different cleaning scenarios. However, as the usage time increases, the spring in this critical part will inevitably wear down, resulting in damage or malfunction. Once the spring fails, the connection stability between the floor brush and the handle will be affected, which will lead to a significant reduction in the cleaning efficiency and user experience of the vacuum cleaner.

[0004] Most vacuum cleaners on the market currently use screws to fix the base of the floor brush and the handle. While this method provides structural stability, it also creates significant inconvenience for subsequent maintenance and repair. When users need to replace damaged internal springs or other accessories, they have to completely disassemble the entire connection. This process is not only tedious and time-consuming, but also carries the risk of damaging other parts of the vacuum cleaner during disassembly and reassembly, potentially affecting its overall performance and lifespan, leading to unnecessary financial losses and user inconvenience. Utility Model Content

[0005] The purpose of this utility model is to address the problem that most vacuum cleaners on the market currently use screws to fix the connection between the floor brush base and the handle. When users need to replace damaged internal springs or other accessories, they have to completely disassemble the connection. This process is not only tedious and time-consuming, but also prone to damage to other parts of the vacuum cleaner during disassembly and reassembly, which may even affect its overall performance and lifespan, causing unnecessary economic losses and inconvenience to users. Therefore, this utility model proposes a floor brush base structure that facilitates the disassembly and assembly of accessories.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a floor brush base structure that facilitates the disassembly and assembly of accessories, comprising: a base connected to the bottom of the floor brush housing, wherein the floor brush housing is provided with a connecting ear, the bottom of the handle is rotatably connected to the inner wall of the connecting ear, and a roller is connected to the outer wall of the connecting ear;

[0007] A fixed shell is connected to the bottom of the base, and a buffer limiter is provided inside the fixed shell for buffering and limiting the handle.

[0008] As a further description of the above technical solution:

[0009] The handle is provided with a first connector and a second connector. The first connector is rotatably connected to the connecting ear on one side, and the second connector is rotatably connected to the connecting ear on the other side. The second connector is located above the buffer limiter.

[0010] As a further description of the above technical solution:

[0011] The second connector is provided with a limiting block. The buffer limiting component includes a spring and an abutment block. The bottom of the fixed shell is provided with a limiting post.

[0034] Please see Figure 1-5 This utility model provides a technical solution: a floor brush base structure that facilitates the disassembly and assembly of accessories, comprising: a base 1, which is connected to the bottom of the floor brush housing 2, the floor brush housing 2 is provided with a connecting ear 4, the bottom of the handle 3 is rotatably connected to the inner wall of the connecting ear 4, and a roller 5 is connected to the outer wall of the connecting ear 4.

[0035] A fixed shell 6 is connected to the bottom of the base 1, and a buffer limiter 7 is provided inside the fixed shell 6 for buffering and limiting the handle 3.

[0036] The handle 3 is provided with a first connector 8 and a second connector 9. The first connector 8 is rotatably connected to the connector ear 4 on one side, and the second connector 9 is rotatably connected to the connector ear 4 on the other side. The second connector 9 is located above the buffer limiter 7.

[0037] The second connector 9 is provided with a limiting block 10. The buffer limiting component includes a spring 71 and an abutment block 72. The bottom of the fixed shell 6 is provided with a limiting post 11. The bottom of the spring 71 is connected to the limiting post 11, and the abutment block 72 is connected to the spring 71. The top of the limiting block is trapezoidal in shape, narrower at the top and wider at the bottom, which allows the handle connection to rotate flexibly at a certain angle during use. The buffer limiting component also prevents the handle from falling directly down when against a wall, thus avoiding difficulty in storage.

[0038] The base 1 is provided with a connecting groove 12, the connecting lug 4 is provided with a first connecting post 13, and the fixing shell 6 is provided with a second connecting post 14. The first connecting post 13 is engaged with the top of the connecting groove 12, and the second connecting post 14 is engaged with the bottom of the connecting groove 12. This facilitates the connection of the base between the connecting lug and the fixing shell using screws.

[0039] The base 1 has an arc-shaped groove 15 inside, and a limiting hole 16 is provided in the arc-shaped groove 15. The abutment block 72 extends through the limiting hole 16 to the bottom of the second connector 9. This facilitates limiting the abutment block and prevents it from deviating excessively.

[0040] The base 1 is provided with a snap-fit ​​hole 17, and the fixing shell 6 is provided with a snap-fit ​​block 18, which snaps into the snap-fit ​​hole 17. This improves the stability of the connection between the base and the fixing shell.

[0041] Working principle: A fixed shell is set at the bottom of the base, and the buffer limiter is set on the fixed shell. The base is provided with a connecting groove, and the connecting ear on the floor brush housing is provided with a first connecting post. The fixed shell is provided with a second connecting post. The first connecting post is connected to the top of the connecting groove, and the second connecting post is connected to the bottom of the connecting groove. The second connecting post is fixed with screws passing through the first connecting post and the connecting groove. When the internal buffer limiter is damaged or fails, the screws can be removed directly, the fixed shell can be taken out, and the buffer limiter on the fixed shell can be replaced. There is no need to disassemble the entire structure, which greatly improves maintenance efficiency.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
