Description

Technical Field

[0001] The utility model belongs to the field of cleaning equipment, and particularly relates to a hair-entangling prevention roller brush assembly, and also relates to a cleaning equipment. Background Art

[0002] At present, common household cleaning appliances on the market, such as vacuum cleaners, mite removers, etc., generally include a roller brush assembly, a motor assembly, and a dust collection assembly. Among them, the motor assembly drives the roller brush in the roller brush assembly to rotate to brush the surface to be cleaned, and the dust on the surface to be cleaned is swept towards the suction port of the dust collection assembly by the bristles on the roller brush, and finally dust collection and suction are realized under the suction force at the suction port.

[0003] However, since traditional roller brushes are all single equal-diameter long roller brushes, during use, the suction force on both sides is weaker than that in the middle, and it is difficult to completely remove hair, which is easy to wind around the surface of the roller body and the rotating shafts at both ends of the roller body. In severe cases, the roller brush will even be wound to death, resulting in the machine being unable to operate normally. Users need to regularly remove the roller brush for cleaning, which is not only cumbersome and inconvenient to operate, but also easy to dirty the user's hands, bringing a bad user experience to the user. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide an improved hair-entangling prevention roller brush assembly.

[0005] At the same time, the utility model also provides a cleaning equipment.

[0006] To solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A hair-entangling prevention roller brush assembly includes a bracket, and a roller brush rotatably connected to the bracket through rotating shafts at the left and right end parts. The outer diameter of the roller brush is gradually reduced from the left and right ends to the middle, and the middle of the roller brush is disconnected to form a channel for hair to pass through; the roller brush assembly further includes two blocking members fixed on the bracket and arranged near the two ends of the roller brush. Each blocking member correspondingly abuts against the roller brush, and as the roller brush rotates around its own central axis, hair gradually converges from the two ends of the roller brush to the middle and is discharged from the channel, and the blocking members synchronously form a blocking area extending circumferentially around the roller brush to block the movement of hair in the corresponding rotating shaft direction.

[0008] According to a specific embodiment and preferred aspect of the utility model, the roller brush includes two roller brush monomers arranged at intervals left and right, and a plurality of leather strips circumferentially distributed at intervals around each roller brush monomer. A channel is formed between the ends of the two roller brush monomers; the width of the channel is 8-20 mm. Herein, the structure is simple and convenient for installation and implementation.

[0009] Preferably, the two roller brush units are arranged symmetrically on the left and right; the roller brush unit on the left side includes an inner support body fixedly connected to the corresponding rotating shaft, a roller sleeved on the inner support body and forming an insertion slot, and a positioning end cap fixedly connected to the right end of the inner support body, and the roller is formed with a plurality of insertion slots extending spirally around its own center line, and a plurality of leather strips are correspondingly inserted into each insertion slot and abut against the positioning end cap from the right end. With a bilaterally symmetrical layout, the spirally extending leather strips on the left and right sides rotate in opposite directions, further enhancing the effect of hair converging from the left and right ends to the middle, which is more conducive to the collection of hair; improving the stability of the leather strips and preventing them from falling off.

[0010] Furthermore, the right end of the drum located on the left side is also formed with a plurality of embedding grooves extending inwardly and connected one-to-one with the plurality of insertion grooves, and the edge of the positioning end cover is formed with protrusions matching one-to-one with the plurality of embedding grooves, the positioning end cover is embedded in the right end of the drum from right to left, and the plurality of protrusions are correspondingly inserted in the plurality of embedding grooves and in conflict with the leather strips.

[0011] Preferably, each embedded groove extends along the axial direction of the drum; and / or each protrusion is arranged flush with the outer wall of the drum; and / or the side wall of the positioning end cap is arranged flush with the end surface of the drum. Here, the gap formed by the splicing between the positioning end cap and the drum extends along the axial direction of the drum, thereby effectively preventing hair from getting stuck in the gap and improving the success rate of smoothly delivering hair into the channel and discharging it.

[0012] Preferably, the roller on the left side is in the shape of a cone which gradually narrows from left to right, and the angle between the generatrix of the roller and the center line is 1°-6°.

[0013] Preferably, the center line of the drum is arranged horizontally, or the angle between the center line of the drum and the horizontal plane is 1°-6°, and the two ends of the leather strip are at the same height from the ground. Here, the brushing and dust collecting capacity of the middle area of ​​the roller brush can be guaranteed.

[0014] According to another specific embodiment and preferred aspect of the utility model, each blocking member is arranged below the roller brush and extends in the front-rear direction, wherein each blocking member is arranged to contact the roller brush from the upper surface. Here, since the outer diameter of the two ends of the roller brush is the largest and closer to the ground, the blocking member can also effectively prevent some ground hair from drilling into the roller brush.

[0015] Preferably, in the orthographic projection on the horizontal plane, a roller brush is provided at the front end and the rear end of each blocking member.

[0016] Preferably, the blocking member is made of plastic, rubber, silicone, or wool.

[0017] Another technical solution of the utility model is a cleaning device, which adopts the above-mentioned anti-hair entanglement roller brush assembly.

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

[0019] The prior art adopts a single roller brush of equal diameter and length. During use, the suction force on both sides is weaker than that in the center, and the hair is difficult to be completely removed. It is easy to be entangled on the surface of the roller and the rotating shafts at both ends of the roller. In severe cases, the roller brush may even be entangled, causing the machine to fail to operate normally. The user is required to remove the roller brush regularly for cleaning, which is not only cumbersome and inconvenient to operate, but also easy to dirty the user's hands, giving the user a bad user experience; the present application comprehensively designs the structure of the roller brush assembly and the cleaning device for preventing hair entanglement, cleverly solving the shortcomings and defects of the prior art. After adopting the roller brush assembly, during cleaning, as the roller brush rotates, the hair gradually gathers from the end with a larger outer diameter on the roller brush to the middle part with a smaller outer diameter and is discharged from the channel in the middle of the roller brush for collection. The blocking members arranged near both ends of the roller brush simultaneously form a blocking area extending around the axial direction of the roller brush, and the blocking area prevents the hair from moving in the direction of the corresponding rotating shaft to avoid being entangled on the rotating shaft. Therefore, compared with the prior art, the utility model, on the one hand, based on the change in the outer diameter of the roller brush, facilitates the hair on the surface of the roller brush to gradually converge from the two ends to the middle as the roller brush rotates, effectively preventing the hair from being entangled on the surface of the roller brush; at the same time, by arranging the blocking parts close to the two ends of the roller brush, it effectively blocks some hair from being entangled on the rotating shaft, ensuring the normal operation of the roller brush; on the other hand, it can effectively reduce the cleaning frequency of the roller brush and significantly improve the user experience.

[0035] Embodiment 1

[0036] As Figures 1 to 5 shown, the hair-entanglement prevention roller brush assembly adopted by the cleaning device according to this embodiment includes a bracket 1, a roller brush 2 rotatably connected to the bracket 1 through a rotating shaft s at the left and right ends, and two blocking members 3 fixed on the bracket 1 and arranged near both ends of the roller brush 2.

[0037] Specifically, the base of the cleaning device is provided with a cleaning window facing the ground, and the roller brush 2 is installed inside the bracket 1 and sweeps the ground through the cleaning window.

[0038] In this example, the outer diameter of the roller brush 2 is gradually decreased from the left and right ends to the middle, and the middle of the roller brush 2 is disconnected to form a channel t for hair to pass through. The width of the channel t can be 8 - 20 mm. As the roller brush 2 rotates around its own center line, the hair gradually converges from both ends of the roller brush 2 to the middle and is discharged from the channel t. It should be particularly noted that the outer diameter of the roller brush 2 in this embodiment is the outer diameter of the cleaning surface formed by the roller brush 2 during rotation.

[0039] In some specific embodiments, the roller brush 2 includes two roller brush monomers 20 arranged at intervals left and right, and multiple leather strips 21 circumferentially distributed at intervals around each roller brush monomer 20. A channel t is formed between the ends of the two roller brush monomers 20; the two roller brush monomers 20 are symmetrically arranged left and right. Therefore, the structure of the roller brush monomer 20 on the left side will be described below, and the structure of the roller brush monomer 20 on the right side is also clearly implementable.

[0040] A plurality of inserting grooves c1 extending spirally around the center line of the roller brush unit 20 located on the left side are formed, and a plurality of leather strips 21 are correspondingly inserted into each inserting groove c1.

[0041] Specifically, the roller brush unit 20 located on the left side includes an inner support body 200 fixedly connected to the corresponding rotating shaft s, a roller 201 sleeved on the inner support body 200 and forming an insertion groove c1, and a positioning end cover 202 fixedly connected to the right end of the inner support body 200 by threaded cooperation. Each leather strip 21 is correspondingly inserted into the insertion groove c1 and abuts against the positioning end cover 202 from the right end. At the same time, the left end of the roller 201 protrudes outward and forms an annular protrusion, and the left end of each leather strip 21 abuts against the annular protrusion.

[0042] For the convenience of implementation, the roller 201 located on the left side is in the shape of a cone which gradually narrows from left to right, and the angle between the generatrix and the center line of the roller 201 is 1°-6°; the center line of the roller 201 is set horizontally, that is, the center lines of the roller 201 and the rotating shaft s coincide and extend horizontally; the right end of the roller 201 located on the left side is also formed with a plurality of embedding grooves c2 which extend inwardly along the axial direction of the roller 201 and are connected with the plurality of insertion grooves c1 in a one-to-one correspondence, and the edge of the positioning end cover 202 is formed with raised portions b which match the plurality of embedded grooves c2 in a one-to-one correspondence, and the positioning end cover 202 is embedded in the right end of the roller 201 from right to left, and the plurality of raised portions b are correspondingly inserted in the plurality of embedded grooves c2 and conflict with the leather strip 21.

[0043] At the same time, each protrusion b is arranged flush with the outer wall of the drum 201 ; the side wall of the positioning end cover 202 is arranged flush with the end surface of the drum 201 .

[0044] In this example, each blocking member 3 contacts the roller brush 2 accordingly, and as the roller brush 2 rotates around its own center line, the blocking member 3 simultaneously forms a blocking area q that extends circumferentially around the roller brush 2 and blocks hair from moving toward the corresponding rotation axis s.

[0045] In some specific embodiments, each blocking member 3 is fixedly mounted on the bracket 2 and located on opposite sides of the cleaning window, and each blocking member 3 is arranged below the roller brush 2 and is in the shape of a long strip extending along the front-to-back direction, wherein each blocking member 3 is arranged to be in conflict with the roller brush 2 from the upper surface, that is, each blocking member 3 can be in conflict with the leather strip 21; in the orthographic projection on the horizontal plane, the front and rear ends of each blocking member 3 both protrude from the roller brush 2; the material of the blocking member 3 is plastic, rubber, silicone, or wool strip.

[0046] In addition, as for other structures of the cleaning device of this embodiment, reference can be made to the vacuum cleaner in the prior art, and no further description will be given here.

[0047] In summary, after adopting this rotary brush assembly, during cleaning, as the rotary brush rotates, the hair gradually converges from the end with a larger outer diameter to the middle with a smaller outer diameter on the rotary brush and is discharged through the channel in the middle of the rotary brush for collection. The blocking members provided near both ends of the rotary brush simultaneously form a blocking area extending along the axial direction of the rotary brush, and the blocking area prevents the hair from moving towards the corresponding rotating shaft direction to avoid entanglement on the rotating shaft. Therefore, compared with the prior art, on the one hand, based on the change in the outer diameter of the rotary brush, it is convenient for the hair on the surface of the rotary brush to gradually converge from both ends to the middle as the rotary brush rotates, effectively preventing the hair from entangling on the surface of the rotary brush; at the same time, by arranging the blocking members near both ends of the rotary brush, part of the hair is effectively blocked from entangling on the rotating shaft, ensuring the normal operation of the rotary brush; on the other hand, it can effectively reduce the cleaning frequency of the rotary brush and significantly improve the user experience; thirdly, adopting a left-right symmetric layout, in this way, the spiral directions of the leather strips extending spirally from left to right are opposite, further enhancing the effect of the hair converging from both left and right ends to the middle, and being more conducive to the collection of curly hair masses; fourthly, adopting a positioning end cap can improve the stability of the leather strip and prevent it from falling off. At the same time, the gap formed by the splicing between the positioning end cap and the drum extends along the axial direction of the drum, thus effectively preventing the hair from getting stuck in the gap and improving the success rate of smoothly feeding the hair into the channel for discharge; fifthly, since the outer diameters at both ends of the rotary brush are the largest and are closer to the ground, the blocking members can also effectively prevent some ground hair from drilling into the inside of the rotary brush; sixthly, the structure is simple and convenient for installation and implementation.

[0048] Embodiment 2

[0049] As Figure 6 shown, compared with Embodiment 1, the rotary brush assembly of this embodiment has basically the same structure, and the difference lies in:

[0050] The heights of both ends of the leather strip 21 in this embodiment from the ground are equal. That is to say, the heights of the left and right ends of the leather strip 21 from the ground are equal when they respectively move to the lowest positions, and the included angle between the center line of the drum 201 and the horizontal plane is 1° - 6°. The center line of the rotating shaft s in this embodiment coincides with the center line of the drum 201, and a channel t that is wider at the bottom and narrower at the top is formed between the two rotary brush units 20. Herein, the brushing ability and dust collection ability in the middle area of the rotary brush can be ensured.

[0051] The above has made a detailed description of the present invention. Its purpose is to enable those skilled in this field of technology to understand the content of the present invention and implement it. However, it cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit and essence of the present invention should be covered within the protection scope of the present invention.
