Description

Technical Field

[0001] This utility model belongs to the field of household appliance technology and relates to a composite brush for cleaning and stain removal. Background Technology

[0002] As the vacuum cleaner industry continues to develop, people's demands for vacuum cleaners are also increasing, and their requirements for the user experience are becoming more stringent. A vacuum cleaner uses an electric motor to drive a cylindrical brush to rotate at high speed, creating negative air pressure within a sealed casing. This vacuum then generates suction to suck up dry pollutants such as dust, hair, and debris, achieving the purpose of cleaning and removing dirt from the room. The brush consists of a roller and brush bristles mounted on the roller.

[0003] However, the existing brush bristle structure is too simple and cannot meet diverse cleaning needs. Therefore, it is essential to design a composite cleaning and stain removal brush. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a composite brush for cleaning and stain removal.

[0005] The purpose of this utility model can be achieved through the following technical solution: a cleaning and stain removal composite brush, including a roller rotatably connected to a vacuum cleaner brush head, characterized in that a brush strip is spirally wound on the side of the roller, the brush strip including short bristles and long bristles, and the height difference between the short bristles and the long bristles is 0.3-3mm.

[0006] The short bristles are soft bristles, the long bristles are hard bristles, and the width ratio of the short bristles to the long bristles is 1:1 to 5:1.

[0007] The short bristles are stiff, the long bristles are soft, and the width ratio of the short bristles to the long bristles is 1:1 to 1:5.

[0008] Both the short and long bristles are made of plastic.

[0009] Both the short and long bristles are made of nylon.

[0010] There is also an adhesive layer between the roller and the brush strip.

[0011] The brush strip includes a short bristle and a long bristle.

[0012] The brush strip includes multiple short bristles and multiple long bristles, with the short bristles and long bristles arranged alternately.

[0013] Compared with existing technologies, this cleaning and stain removal composite brush has the following advantages: This invention designs two types of brush strips, one long and one short, spirally wound around a roller. When the short bristles are soft and the long bristles are hard, the brush's scraping and mopping functions are enhanced, making it better suited for cleaning large particles of dust. Conversely, when the short bristles are hard and the long bristles are soft, the brush's mopping functions are enhanced, making it better suited for cleaning small particles of dust. This design better meets the needs of different cleaning operations and is highly practical. Attached Figure Description

Detailed Implementation

[0015] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments. Example 1:

[0016] like Figure 1 As shown, this cleaning and stain removal composite brush includes a roller 1 rotatably connected to the vacuum cleaner brush head. A brush strip 2 is spirally wound on the side of the roller 1. The brush strip 2 includes short bristles 2a and long bristles 2b. The height difference between the short bristles 2a and the long bristles 2b is 0.3-3mm; specifically, the height difference between the short bristles 2a and the long bristles 2b is 0.4mm.

[0017] The short bristles 2a are soft bristles, and the long bristles 2b are hard bristles. The width ratio of the short bristles 2a to the long bristles 2b is 1:1 to 5:1; specifically, the width ratio of the short bristles 2a to the long bristles 2b is 4:1.

[0018] Both the short bristles 2a and the long bristles 2b are made of plastic.

[0019] Both the short bristles 2a and the long bristles 2b are made of nylon.

[0020] There is also an adhesive layer 3 between the roller 1 and the brush strip 2, which is an existing product.

[0021] The brush strip 2 includes a short bristle 2a and a long bristle 2b.

[0022] The roller 1 also has a reinforcing strip 1a, the cross section of which is trapezoidal or square.

[0023] By adopting this structure, the brush strip 2 is designed in two forms, long and short. When the short brush bristles 2a are soft and the long brush bristles 2b are hard, the brush has both sweeping and mopping functions, which enhances the sweeping performance of the brush and makes it more suitable for cleaning large particles of dust. Example 2:

[0024] like Figure 2 As shown, the content of this second embodiment is largely the same as that of the first embodiment, except that the brush strip 2 in the first embodiment includes a short bristle 2a and a long bristle 2b; while in this second embodiment, as shown... Figure 2 As shown, the brush strip 2 includes multiple short bristles 2a and multiple long bristles 2b, and the short bristles 2a and long bristles 2b are arranged alternately; specifically, the brush strip 2 includes two short bristles 2a and two long bristles 2b. Example 3:

[0025] like Figure 3 As shown, the content of this embodiment three is largely the same as that of embodiment one, except that in embodiment one, the short bristles 2a are soft bristles and the long bristles 2b are hard bristles, and the width ratio of the short bristles 2a to the long bristles 2b is 1:1 to 5:1; specifically, the width ratio of the short bristles 2a to the long bristles 2b is 4:1; while in this embodiment three, as... Figure 3 As shown, the short bristles 2a are hard bristles, and the long bristles 2b are soft bristles. The width ratio between the short bristles 2a and the long bristles 2b is 1:1 to 1:5; specifically, the width ratio between the short bristles 2a and the long bristles 2b is 1:4. By designing the brush strip 2 into two forms, when the short bristles 2a are hard bristles and the long bristles 2b are soft bristles, the brush's floor-wiping performance is enhanced while it has both sweeping and floor-wiping functions, thus making the brush better suited for cleaning small particulate dust. Example 4:

[0026] like Figure 4 As shown, the content of this embodiment four is largely the same as that of embodiment three, except that the brush strip 2 in embodiment three includes a short bristle 2a and a long bristle 2b; while in this embodiment four, as shown... Figure 4 As shown, the brush strip 2 includes multiple short bristles 2a and multiple long bristles 2b, and the short bristles 2a and long bristles 2b are arranged alternately; specifically, the brush strip 2 includes two short bristles 2a and two long bristles 2b.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0028] Although this document frequently uses terms such as 1. roller; 1a. reinforcing strip; 2. brush strip; 2a. short bristles; 2b. long bristles; and 3. adhesive layer, the possibility of using other terms is not excluded.
