DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0032] Please refer to Figure 1-11 ;

[0033] The cleaning assembly described in the utility model is generally used in cleaning devices, such as vacuum cleaners or sweeping robots, etc., to reduce hair entanglement, facilitate people's cleaning, and improve the cleaning effect; it specifically includes a shell 11 and a receiving chamber 12 arranged in the shell 11, the shell 11 is provided with a dust collecting port 13 connected to the receiving chamber 12, and the dust collecting port 13 can be set at an eccentric position according to actual conditions, and the sizes of the roller brush assembly 1 2 and the roller brush assembly 2 3 are adjusted accordingly, preferably set in the middle position, and the dust collecting port 13 is used to communicate with the negative pressure generator of the cleaning device, and finally form a negative pressure in the receiving chamber 12; the receiving chamber 12 is installed with a roller brush assembly 1 2 and a roller brush assembly 2 3, wherein the roller brush assembly 1 2 and the roller brush assembly 2 3 are connected to the receiving chamber 12. The roller brush assemblies 1 and 2 3 can be detachably connected to the shell 11, respectively, so that people can clean it conveniently; in this embodiment, the receiving chamber 12 is also in the shape of an elongated strip, and the roller brush assemblies 1 and 2 3 are arranged in a straight line in the receiving chamber 12, that is, the ends of the roller brush assemblies 1 and 2 3 that are far away from each other are respectively connected to the two ends of the receiving chamber 12, and the other ends that are relatively close to each other are arranged oppositely, and the interval space 4 formed at a distance at the opposite ends is formed, and the interval space 4 and the dust collecting port 13 form an airway correspondingly; it should be noted that the roller brush assemblies 1 and 2 3 in this embodiment can be powered or not, but when they are not powered, the cleaning device needs to provide corresponding power to make them move;

[0034] During operation, negative pressure is formed at the dust collecting port 13. Since the setting of the interval space 4 does not block the dust collecting port 13, a trumpet-shaped adsorption area is formed outward from the interval space 4. When the roller brush assembly 1 2 and the roller brush assembly 2 3 rotate to bring up the dust on the bottom surface, the dust will naturally move toward the adsorption area, that is, the dust will move toward the middle and away from the rotating shaft 72 of the roller brush assembly 1 2 and the roller brush assembly 2 3, thereby effectively avoiding the problem of dust accumulation at the rotating shaft 72. Of course, when it is necessary to clean the hair, the hair will also move toward the adsorption area and away from the rotating shaft 72 of the roller brush assembly 1 2 and the roller brush assembly 2 3, effectively solving the problem of hair entangled on the rotating shaft 72, and being able to maintain the cleaning effect of the equipment for a long time.

[0035] It should be noted that after the roller brush assembly 1 2 and the roller brush assembly 2 3 are placed in the receiving cavity 12 , there are gaps between them and the shell 11 , so there is still an adsorption effect from the gaps, but mainly in the formed adsorption area.

[0036] A plurality of arc-shaped windshield plates 5 are provided at the opening edge of the receiving chamber 12, and the arc-shaped windshield plates 5 extend to the outside of the roller brush assembly 1 2 and the roller brush assembly 2 3. It can be understood that the arc-shaped windshield plates 5 partially wrap the roller brush assembly 1 2 and the roller brush assembly 2 3 from the outside, thereby reducing the opening area of ​​the receiving chamber 12. The arc-shaped windshield plates 5 have two configuration modes;

[0037] The first embodiment, referring to Figure 8 and Fig. 9 The arc-shaped wind shield 5 is located on the front side. Preferably, the arc-shaped wind shield 5 is made of soft rubber material. When working, under the condition of the same adsorption force, the opening area of ​​the accommodating chamber 12 can be reduced by a plurality of arc-shaped wind shields 5, so that the adsorption force can be enhanced without affecting the dust collection. In addition, when cleaning, if the garbage is some dust or hair, it can pass through the lower end of a plurality of arc-shaped wind shields 5, and then quietly enter the range of the roller brush assembly 1 2 and the roller brush assembly 2 3 and be cleaned; if the garbage is some larger objects, these objects will contact the arc-shaped wind shield 5 and push it toward the roller brush assembly 1 2 or the roller brush assembly 2 3, and finally conflict with the brush of the roller brush assembly 1 2 or the roller brush assembly 2 3, so that it stops running and avoids the larger particles being sucked into it and causing damage.

[0038] In the second embodiment, the curved wind shield 5 is located on the rear side. Under normal circumstances, the ends of several curved wind shields 5 are in contact with the bottom surface. Under normal conditions, the roller brush assembly 1 2 and the roller brush assembly 2 3 must contact the bottom surface before the curved wind shield 5. When working, under the condition of the same adsorption force, the opening area of ​​the receiving chamber 12 is reduced by several curved wind shields 5, so that the adsorption force can be strengthened without affecting the dust collection. Several curved wind shields 5 are located on the rear side, which can make it easier to collect garbage, reduce the probability of garbage escape, and improve the cleaning effect.

[0039] Based on the first embodiment and the second embodiment, the length of the arc-shaped wind shield 5 corresponding to the dust collecting port 13 is greater than the lengths of other wind shields. Such a structure further reduces the area of ​​the partition space 4, so that the gas flow rate at the partition space 4 is greater than the flow rate at other positions, which is conducive to the dust or hair moving to the middle and avoiding accumulation at the two ends of the roller brush assembly 1 2 and the roller brush assembly 2 3.

[0040] The roller brush assembly 1 2 and the roller brush assembly 2 3 described in the utility model can use separate drive assemblies, referring to Figure 1 For example, a drive 71 and a rotating shaft 72 are connected in a transmission manner, wherein the drive 71 is mounted on the housing 11, and one end of the rotating shaft 72 is connected to the drive 71, and the other end extends into the receiving chamber 12, and the other end of the rotating shaft 72 is connected to the roller brush assembly 2; or they share a driving assembly for transmission connection, refer to Figure 7 For example, it includes a double-headed driving motor 61, both ends of the double-headed driving motor 61 are respectively connected to a transmission shaft 62, the transmission shaft 62 is connected to a transmission box 63, and the two transmission boxes are installed on both sides of the shell 11 and are respectively connected to the roller brush assembly 1 2 and the roller brush assembly 2 3.

[0041] The first embodiment of the utility model regarding the roller brush assembly is as follows: Figure 4-Figure 6Of course, the structures of the roller brush assembly 1 2 and the roller brush assembly 2 3 are the same, specifically including a fixing member 21, which is fixedly connected to the silicone roller brush 22. The silicone roller brush 22 is hollow and therefore has a compression space. Of course, the rotating shaft 72 can pass through the hollow position of the silicone roller brush 22 and be connected to the other end. At this time, there is a gap between the rotating shaft 72 and the inside of the silicone roller brush 22 for compression deformation; in one embodiment, the fixing member 21 is circular, and the hollow position of the silicone roller brush 22 is also circular. When connected, the silicone roller brush 22 can be connected by interference fit. One end of the brush 22 is connected to the fixing piece 21. When it needs to be disassembled for cleaning, it is only necessary to apply a pulling force to the silicone roller brush 22 in the direction away from the fixing piece 21. Of course, it can also be fixed with screws. For example, a plurality of threaded holes are provided on the side of the fixing piece 21, and a plurality of through holes are provided on one side of the silicone roller brush 22. When assembling, the silicone roller brush 22 is fixed to the fixing piece 21 by interference fit, and the through holes are made to correspond to the threaded holes. Finally, screws are used to pass through the through holes and connect with the threaded holes, and the silicone roller brush 22 can be fixed to the fixing piece 21.

[0042] In addition, the silicone roller brush 22 will contact the bottom surface in any state. When in use, it rotates to use friction to drive up dust and hair on the bottom surface. The hollow setting can make the bristles deform inward by elastic deformation when contacting the bottom surface, which is more obvious when encountering an uneven bottom surface. The deformation can maintain full contact with the bottom surface and keep the cleaning device body running smoothly.

[0043] Furthermore, the silicone roller brush 22 includes a cylindrical fixing portion 221, and a cleaning piece 1 222 and a cleaning piece 223 are arranged at intervals on the outer periphery of the fixing portion 221. The cleaning piece 1 222 and the cleaning piece 223 are inclined along the axial and radial directions of the fixing portion 221. The axial inclination will form an inclined guide channel between the adjacent cleaning pieces 1 222 and the cleaning pieces 2 223, which guides the dust and hair entering the channel to move in the direction of the adsorption area to avoid accumulation at the end, and the radial inclination is in line with the movement direction of the silicone roller brush 22. In this embodiment, the cleaning piece 1 222 and the cleaning piece 2 223 have different cleaning effects, wherein the cleaning piece 1 222 is arranged at the outer end thereof. There is a resistance end 224. When the resistance end 224 contacts the bottom surface, a large friction force is generated, thereby having a slapping effect on the dust or hair adhered to the bottom surface, so that the dust and hair are separated from the bottom surface. Of course, the silicone roller brush 22 rotates rapidly and will slap the dust and hair multiple times, and these slapping effects only play a role in the slight adhesion of the dust and hair. After the dust and hair are separated from the bottom surface, they need to be pushed to the adsorption area through the cleaning piece 223. The outer end of the cleaning piece 223 is the cut surface end 225. When the end of the cleaning piece 223 contacts the bottom surface, the cut surface end 225 can be completely fitted with the bottom surface, thereby pushing the dust and hair to the adsorption area.

[0044] In this embodiment, the thickness of cleaning sheet 1 222 is less than the thickness of cleaning sheet 223, and the width of cleaning sheet 1 222 is greater than the width of cleaning sheet 223, that is, cleaning sheet 1 222 has better softness, and cleaning sheet 1 222 has a longer contact time with the bottom surface, which is more conducive to the slapping effect of the bottom surface during the rotation of the fixed part 221. The main function of cleaning sheet 223 is to push dust and hair into the adsorption area, so it is necessary to maintain the movement direction to achieve the pushing effect on dust and hair, and there is no need to contact with the bottom surface for a long time. In addition, cleaning sheet 1 222 and cleaning sheet 2 223 are respectively continuous sheets, which can generate greater friction than the brush in the prior art, avoid hair entanglement, and achieve a better cleaning effect.

[0045] Furthermore, the ends of the cleaning piece 1 222 and the cleaning piece 2 223 close to the dust collecting port 13 are both provided with an inclined surface, which can reduce the obstruction to the negative pressure airflow and is more conducive to forming a trumpet-shaped adsorption area.

[0046] The utility model is about the second embodiment of the roller brush assembly 2, referring to Figure 8-Figure 10 Of course, the structures of the roller brush assembly 1 2 and the roller brush assembly 2 3 are the same, specifically including a fixed shaft 23, on which are provided four cleaning sheets 3 24 that rotate 90° from one end to the other end, located between two cleaning sheets 3 24, and a guide groove 25 is formed on the fixed shaft 23; of course, the guide groove 25 is a complete guide track; when working, the cleaning sheets 3 24 on the roller brush assembly 1 2 and the roller brush assembly 2 3 gradually contact the bottom surface from the end to the middle;

[0047] It should be noted that the cleaning sheet 3 24 is made of continuous silicone or flexible plastic.

[0048] At the beginning, the end of the cleaning sheet 3 24 contacts the bottom surface. At this time, the opening space of the guide groove 25 gradually increases from the end to the middle. The middle position is larger, so a trumpet-shaped negative pressure space is formed, which is conducive to dust entering the guide groove 25 from both ends. As the guide groove 25 component rotates, the opening of the component gradually decreases from the end to the middle, that is, as the suction component at the middle position is rotated, the dust drawn into the guide groove 25 gradually moves to the middle, thereby avoiding accumulation at the end.

[0049] Further, refer to Fig. 9 and Fig.11 By using four cleaning sheets 3 24 that are rotated 90°, it can be ensured that the guide groove 25 is large enough, and after rotating 90°, the end of the first cleaning sheet 3 24 close to the middle and the end of the second cleaning sheet 3 24 close to the end can contact the bottom surface at the same time. At the same time, the guide groove 25 formed is exactly parallel to the bottom surface, which can make it easier to absorb and guide dust.

[0050] Furthermore, the guide groove 25 is gradually inclined from the end toward the dust collecting port 13 to enhance the dust guiding effect. In addition, there are four guide grooves 25, of which the radial heights of the two symmetrical guide grooves 25 are greater than the heights of the other two guide grooves 25; for example, the fixed shaft 23 is a rectangular parallelepiped, which is rotated 90° about the center to form a spiral state, and the four cleaning sheets 24 are respectively arranged at the positions of the four sides. From the cross-section, the heights of the two wide ones are higher than the heights of the two long ones; from the cross-section again, the spatial area of ​​the guide groove 25 formed by the two wide ones is smaller than the spatial area of ​​the guide groove 25 formed by the two long ones; the airflow velocity formed by the two wide ones is greater than the airflow velocity formed by the two long ones, so the guide groove 25 with a small space is more likely to attract hair or dust, while the guide groove 25 with a large space is more likely to allow larger particles of garbage to enter.
