Description

Technical Field

[0001] The utility model belongs to the field of cleaning equipment, and in particular relates to a brush sweeping module group for preventing hair from winding, and also relates to a roller brush with the brush sweeping module group. Background Art

[0002] The working principle of a vacuum cleaner is that the vacuum cleaner motor rotates at high speed, sucking in air from the suction port, creating a certain vacuum in the dust box. The dust enters the dust filter bag in the dust box through the floor brush, connecting pipe, handle, hose, and main suction pipe. The dust is retained in the dust filter bag, and the filtered air passes through a layer of filter and enters the motor.

[0003] At present, the existing vacuum cleaners are usually provided with a roller brush at the suction port. The surface of the roller brush is provided with a strip composed of multiple bristles. When the roller brush rotates, the multiple bristles in the strip contact the ground to sweep dust and other garbage into the suction port to clean the ground.

[0004] However, in actual use, due to the gaps between the multiple bristles in the hair strip, the hair on the ground can easily get stuck in the gaps between the bristles, and as the roller brush rotates, the hair can easily get stuck inward into the hair strip and gradually entangled on the surface of the roller brush, affecting the cleaning effect of the roller brush. The user needs to frequently disassemble the roller brush for cleaning, which is cumbersome and inconvenient to operate, and can easily cause the user's hands to be contaminated with dust, greatly affecting the user experience. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a new brushing module for preventing hair entanglement.

[0006] At the same time, the utility model also provides a roller brush.

[0007] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0008] A brush sweeping module for preventing hair entanglement comprises a blocking strip and a wool strip, wherein the blocking strip comprises a connecting portion and a blocking portion extending outward from the connecting portion, wherein the connecting portion is formed with an insertion groove arranged along its length direction; the wool strip comprises a wool strip body and an insertion portion formed at the bottom end of the wool strip body and matching with the insertion groove, wherein during assembly, the insertion portion is inserted into the insertion groove from one end of the insertion groove, and the blocking portion blocks at least one side of the wool strip body.

[0009] According to a specific implementation and preferred aspect of the utility model, the blocking strip blocks one side of the wool strip body, or the blocking strip blocks both sides of the wool strip at the same time. The blocking strip simultaneously forms a blocking area on one side or both sides of the wool strip to prevent ground hair from getting stuck in the wool strip.

[0010] Preferably, the top end of the wool strip body extends out of the blocking portion to form a brushing edge.

[0011] Specifically, the height of the blocking portion is h1, and the height of the wool strip body is h2, wherein 0.8h2≤h1≤0.9h2.

[0012] According to another specific implementation and preferred aspect of the utility model, the cross-section of the wool top is T-shaped; and / or the wool top is linear, V-shaped, or spiral.

[0013] According to another specific implementation and preferred aspect of the utility model, the hardness of the connecting part is greater than that of the blocking part; and / or the blocking part is made of leather. Here, while achieving the flexibility of the blocking part on the blocking strip, the stability of the connection with the roller brush body can also be ensured, avoiding the roller brush body from falling off during rotation, thereby improving the reliability of the roller brush.

[0014] According to another specific implementation and preferred aspect of the utility model, the blocking portion has an elastic tendency to press against the wool top, thereby ensuring that the blocking portion remains close to the wool top.

[0015] Another technical solution of the utility model is a roller brush, which includes a roller brush body, and the roller brush also includes the above-mentioned brush sweeping module group, wherein the brush sweeping module group is arranged on the roller brush body, and as the roller brush body rotates, the brush sweeping module group brushes the ground synchronously.

[0016] Preferably, there are multiple groups of brush sweeping modules, which are distributed at intervals around the circumference of the roller brush body.

[0017] In addition, a T-shaped connecting groove is formed on the surface of the roller brush body and is arranged along its length direction, and the blocking strip can be inserted into the connecting groove from one end or the other end of the connecting groove; and / or, the roller brush body includes a roller brush body and connecting end plates arranged at both ends of the roller brush body, wherein each connecting end plate is formed with a notch, and the two ends of the wool strip and / or the blocking strip are correspondingly inserted into each notch. Here, the disassembly and assembly of the blocking strip is simple and convenient; at the same time, the positioning of the two ends of the wool strip by the roller brush body can improve the stability of the wool strip, and prevent the wool strip from deforming and falling off during the high-speed rotation of the roller brush body.

[0018] Due to the implementation of the above technical solution, the utility model has the following advantages compared with the prior art:

[0019] When using the roller brush of the prior art, hair is easily entangled on the surface of the roller brush, affecting the cleaning effect of the roller brush. The user needs to frequently disassemble the roller brush for cleaning, which is cumbersome and inconvenient to operate, and it is easy to cause the user's hands to be contaminated with dust, which greatly affects the user experience. The present application makes an overall design of the structure of the brush sweeping module and the roller brush to prevent hair entanglement, which ingeniously solves the shortcomings and defects of the prior art. After adopting the brush sweeping module, the hair strip and the blocking strip are assembled as one piece through the cooperation of the insertion part and the connecting part. During cleaning, as the roller brush body rotates, the brush sweeping edge of the hair strip brushes the ground, and the blocking part synchronously blocks at least one side of the hair strip body to prevent the ground hair from being stuck in the hair strip, thereby preventing the hair from being entangled on the surface of the roller brush. Therefore, compared with the prior art, the present invention can, on the one hand, prevent the ground hair from being stuck in the hair strip through the blocking strip without affecting the normal brush sweeping function, effectively preventing the hair from being entangled on the surface of the roller brush, thereby greatly reducing the frequency of disassembling and cleaning the roller brush, being simple and convenient to use, and effectively improving the user experience; on the other hand, the blocking strip and the hair strip are assembled as one piece, which improves the compactness of the structure between the blocking strip and the hair strip, which not only improves the blocking effect on the hair, but also has a small volume, thereby avoiding the blocking strip from interfering with the normal dust collection.

Example 1

[0033] like Figures 1 to 4 As shown, a hair entanglement-preventing roller brush of this embodiment includes a roller brush body 1 and a brush sweeping module arranged on the roller brush body 1.

[0034] Specifically, the roller brush body 1 includes a roller brush body 10 and connecting end plates 11 arranged at both ends of the roller brush body 10 .

[0035] In this example, there are three groups of brush sweeping module groups and they are evenly spaced around the center line of the roller brush body 10. Each group of brush sweeping module groups includes a corresponding matching blocking strip 2 and a hair strip 3. The hair strip 3 is composed of multiple bristles, and in some specific embodiments, the blocking strip 2 and the hair strip 3 are both V-shaped; in other specific embodiments, the blocking strip 2 and the hair strip 3 can also be straight, or spirally extended from one end of the roller brush body 1 to the other end.

[0036] In order to facilitate disassembly and assembly, a T-shaped connecting groove c1 is formed on the surface of the roller brush body 10 and is arranged along its length direction, and there are three connecting grooves c1 and they correspond one to one to the three blocking strips 2; each blocking strip 2 includes a connecting portion 20 connected to the roller brush body 1 and a blocking portion 21 extending from the connecting portion 20 in a direction away from the roller brush body 1, wherein the connecting portion 20 matches the connecting groove c1, and the connecting portion 20 can be inserted into the connecting groove c1 from one end or the other end of the connecting groove c1.

[0037] Meanwhile, the hardness of the connecting portion 20 is greater than that of the blocking portion 21 ; the blocking portion 21 is made of leather.

[0038] That is to say, the blocking portion 21 is provided with a blocking strip 2, and when assembled, the blocking strip 2 is in contact with the front side of the wool strip 3; the brushing edge formed by the wool strip 3 protrudes outward from the blocking strip 2; as the roller brush body 1 rotates, the wool strip 3 brushes the ground with its brushing edge, and the blocking strip 2 synchronously forms a blocking area on the front side of the wool strip 3 to prevent the hair on the ground from being stuck in the wool strip 3.

[0039] In this embodiment, during assembly, the blocking portion 21 contacts the front side of the wool strip 3, and the blocking portion 21 has an elastic tendency to press against the wool strip 3. It should be particularly noted that the front side of the wool strip 3 in this embodiment refers to the side of the wool strip 3 that first contacts the ground when the roller brush body 1 rotates.

[0040] In order to further facilitate assembly and disassembly, the wool strip 3 is connected to the connecting portion 20 and contacts the blocking portion 21 from the front.

[0041] Specifically, the connecting portion 20 is also formed with a T-shaped insertion groove c2 that penetrates along its own length direction. The wool strip 3 includes a wool strip body 30, an insertion portion 31 formed at the bottom end of the wool strip body 30 and matching the insertion groove c2, and the insertion portion 31 is inserted into the insertion groove c2 from one end or the other end of the insertion groove c2; a notch k is formed on each connecting end plate 11, and the two ends of the wool strip 3 and / or the blocking strip 2 are correspondingly inserted into each notch k.

[0042] Meanwhile, the height of the blocking portion 21 is h1, and the height of the wool strip body 30 is h2, wherein 0.8h2≤h1≤0.9h2. In the present embodiment, h1=0.845h2.

[0043] In summary, after adopting the brush sweeping module, the hair strip and the blocking strip are integrated into one piece through the cooperation of the inserting part and the connecting part, and during cleaning, as the roller brush body rotates, the brushing edge of the hair strip brushes the ground, and the blocking part synchronously blocks at least one side of the hair strip body to prevent the ground hair from getting stuck in the hair strip, thereby preventing the hair from getting entangled on the surface of the roller brush. Therefore, compared with the prior art, the utility model can prevent the ground hair from getting stuck in the hair strip through the blocking strip without affecting the normal brush sweeping function, effectively preventing the hair from getting entangled on the surface of the roller brush, thereby greatly reducing the frequency of disassembling and cleaning the roller brush, which is simple and convenient to use, and effectively improves the user experience; on the other hand, the blocking strip and the hair strip are integrated into one piece The compactness of the structure between the blocking strip and the wool strip is improved, which not only improves the blocking effect on hair but also has a small size, thereby preventing the blocking strip from interfering with normal vacuuming; thirdly, the blocking portion has an elastic tendency to press in the direction of the wool strip, thereby ensuring that the blocking portion always remains close to the wool strip; fourthly, while achieving the flexibility of the blocking portion on the blocking strip, the stability of the connection with the roller brush body can be ensured, thereby preventing the wool strip from falling off during the rotation of the roller brush body and improving the reliability of the roller brush; fifthly, by positioning the two ends of the wool strip by the roller brush body, the stability of the wool strip can be improved, thereby preventing the wool strip from deforming and falling off during the high-speed rotation of the roller brush body; sixthly, the disassembly and assembly of the blocking strip and the wool strip are simple and convenient. Example 2

[0044] like Figure 5 As shown, the roller brush of this embodiment has a substantially same structure as that of embodiment 1, except that:

[0045] In the brushing module of this embodiment, two blocking parts 21 are provided. During assembly, the blocking strip 2 is in synchronous contact with the front and back sides of the wool strip 3 through the blocking parts 21, so as to achieve the effect of preventing hair entanglement when the roller brush is switched forward and reverse. At the same time, under the interference of the two blocking parts 21, the stretchability of the wool strip 3 is maintained, thereby ensuring the brushing effect and extending the service life.
