Description

Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, in particular to an anti-winding roller brush and cleaning equipment. Background Art

[0002] With the development of technology, cleaning robots are becoming more and more popular in households. Generally, a cleaning robot includes a cleaning robot body, a dust box or dust cup installed in the cleaning robot body, an air pump that provides negative pressure, a roller brush that rotates in the cleaning robot body, and a motor that drives the roller brush to rotate. Dust or hair is collected into the dust box or dust cup under the action of the air pump and the roller brush.

[0003] In the prior art, when the roller brush is used for a long time, winding objects (for example, hair, silk thread and other long strip objects) are easy to be entangled on the roller brush, thereby increasing the motor load and reducing the cleaning effect. If the winding objects are entangled at the output end of the motor, it is easy to burn the motor. For this reason, the Chinese invention patent application with the application publication number "CN112515551A" and the invention name "Anti-entanglement cleaning roller brush and cleaning robot" discloses a method in which a gap is set in the roller brush body, a screw rod, a limiter and a cutting member are set in the inner cavity of the roller brush body, the limiter is set on the screw rod, and the cutting member is set on the limiter. The cutting member extends out of the gap and reciprocates under the drive of the screw rod and the limiter to cut the winding objects entangled on the roller brush body. However, this technical solution also has some shortcomings. For example, the cutting member is built into the roller brush body. Since it needs to reserve a gap between the scraping strips for the cutting member to pass through, the number of scraping strips or hair strips allowed to be set on the roller brush will be reduced, affecting the cleaning efficiency; and the roller brush structure of this structure is complex and the manufacturing cost is high.

[0004] Therefore, an anti-entanglement roller brush and cleaning device with a relatively simple structure and in which the entangled objects are not easily entangled need to be designed. Utility Model Content

[0015] Optionally, the anti-entanglement roller brush also includes a connecting end cover, and the end of the connecting end cover away from the driving member is assembled in the cleaning device, and the support shaft is rotatably connected to the connecting end cover through a bearing to realize the rotating assembly of the support shaft and the cleaning device; the cutting member is arranged at the end of the connecting end cover close to the driving member.

[0046] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0047] It should be noted that the terms "center", "longitudinal", "lateral", "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", "back", "side", "circumferential" and the like in the present invention indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as a limitation on the present invention. In addition, the words "first", "second" and the like are only used to distinguish multiple components or structures with the same or similar structures, and do not represent any special limitation on the setting order or connection relationship.

[0048] Please refer to Figures 1 to 11, the embodiment of the utility model provides an anti-entanglement roller brush 100, which is used to be assembled into a cleaning device 1000 to clean dust, debris and other debris on the floor. It should be noted that the cleaning device 1000 can be a cleaning appliance such as a vacuum cleaner and a cleaning robot. The anti-entanglement roller brush 100 includes a roller brush body 1, a winding gathering bone position 4 and a cutting member 5. Among them, the roller brush body 1 has a first end a connected to the driving member in a transmission manner, and a second end b away from the driving member; in this embodiment, the first end a of the roller brush body 1 is fixedly connected to the output end of the driving member to receive the torque of the driving member, and then rotates relative to the surface to be cleaned to clean the cleaning surface. Specifically, in this embodiment, the driving member is a roller brush box assembly 300 having a driving motor and a transmission mechanism. Of course, in other embodiments, the first end a of the roller brush body 1 can be directly assembled with the output end of the driving motor, and no specific limitation is made here. The outer diameter of the second end b of the roller brush body 1 is smaller than the outer diameter of the first end a of the roller brush body 1; the outer periphery of the roller brush body 1 is obliquely configured with a cleaning strip 13, and the inclination direction of the cleaning strip 13 is in the same direction as the rotation direction of the roller brush body 1. Specifically, in this embodiment, a plurality of cleaning strips 13 are alternately arranged in the circumference of the roller brush body 1, and the cleaning strips 13 and the roller brush body 1 are configured as a whole. Of course, in other embodiments, the cleaning strips 13 and the roller brush body 1 can also be configured separately, and the assembly and fixation are realized by a detachable connection; there is no specific limitation. The outer periphery of the roller brush body 1 is obliquely configured with a cleaning strip 13, which means that the cleaning strip 13 is not configured on the outer periphery of the roller brush body 1 parallel to the central axis of the roller brush body 1, but has a certain inclination angle α with the central axis of the roller brush body 1. When working, the driving member drives the roller brush body 1 to rotate clockwise, and the roller brush body 1 scrapes and brushes the cleaning surface through the cleaning strip 13. The cleaning strip 13 is configured on the outer periphery of the roller brush body 1 obliquely downward from the first end a to the second end b. The winding gathering bone 4 is coaxially arranged at the second end b of the roller brush body 1, and is used for winding the winding (not shown in the figure) guided to the second end b; during operation, the winding will gather toward the second end b after being guided by the roller brush body 1, and the gathered winding will be wound on the outer peripheral surface of the winding gathering bone 4. The cutting member 5 is arranged on the side of the second end b of the roller brush body 1, and is used for winding the cutting member 5 on the surface of the winding gathering bone 4 when the roller brush body 1 rotates relative to the cutting member 5. Specifically, the cutting member 5 includes a blade structure, and the blade structure and the outer periphery of the gathered winding are arranged to intersect, so that when the winding gathering bone 4 rotates, the winding wound on the winding gathering bone 4 will be cut off by the cutting member 5, so that it can no longer be wound on the outer periphery of the winding gathering bone 4, and then sucked into the dust box 210 of the cleaning device 1000 under the action of the suction device (not shown in the figure).

[0049] Since the outer diameter of the second end b of the roller brush body 1 of the anti-entanglement roller brush 100 is smaller than the outer diameter of the first end a of the roller brush body 1; the outer periphery of the roller brush body 1 is inclinedly provided with a cleaning strip 13, and the inclination direction of the cleaning strip 13 is in the same direction as the rotation direction of the roller brush body 1; during operation, the windings will be gathered and collected toward the second end b under the guidance of the roller brush body 1 with the guide structure, and will be wound around the outer periphery of the winding gathering bone position 4 at the second end b; since the outer periphery of the winding gathering bone position 4 rotates relative to the cutting member 5, the windings on the outer periphery of the winding gathering bone position 4 will be cut off by the cutting member 5, so that they cannot continue to be wound around the outer periphery of the winding gathering bone position 4, and then be sucked into the dust box 210 of the cleaning device 1000 under the action of the suction device. In this way, the anti-entanglement roller brush 100 has the advantages that the windings are not easy to be entangled and the structure is relatively simple.

[0050] Optionally, see Figure 6 , Figure 7 , Figures 9 to 11 In this embodiment, the second end b of the roller brush body 1 is provided with a first end cap 2; the first end cap 2 can seal the second end b of the roller brush body 1, so that dust, entangled objects, etc. cannot enter the roller brush body 1 to damage the roller brush body 1. The entanglement gathering bone 4 is arranged on the side of the first end cap 2 away from the driving member; optionally, in this embodiment, the entanglement gathering bone 4 is sleeve-shaped, and the cross-section of its outer periphery is elliptical, and the center of the entanglement gathering bone 4 is rotatably assembled through the support shaft 7 and the cleaning device 1000; the cutting member 5 and the support shaft 7 are coaxially arranged and located in an annular area with the center of the entanglement gathering bone 4 as the center of the circle, the long semi-axis of the ellipse of the entanglement gathering bone 4 as the outer diameter, and the short semi-axis of the ellipse of the entanglement gathering bone 4 as the inner diameter; the entanglement gathering bone 4 has an avoidance groove c for avoiding the cutting member 5. Since the cutting member 5 and the supporting shaft 7 are coaxially arranged and are located in an annular region with the center of the winding gathering bone position 4 as the center of the circle, the long semi-axis of the ellipse of the winding gathering bone position 4 as the outer diameter, and the short semi-axis of the ellipse of the winding gathering bone position 4 as the inner diameter, when the winding gathering bone position 4 rotates relative to the cutting member 5, the windings wound on the winding gathering bone position 4 will be cut off by the cutting member 5, so that they can no longer be wound around the outer periphery of the winding gathering bone position 4, and then sucked into the dust box 210 of the cleaning device 1000 under the action of the suction device. Optionally, the cutting member 5 can be fixed on the side of the second end b of the roller brush body 1; it can also be rotatably arranged on the side of the second end b of the roller brush body 1, but when working, the rotation direction of the cutting member 5 must be opposite to the rotation direction of the winding gathering bone position 4 to form relative rotation.

[0051] In order to allow the cut windings to be smoothly sucked into the dust box 210, optionally, please refer to Figure 2 and Fig.11In this embodiment, the cutting member 5 has a blade edge 51 intersecting with the outer periphery of the cross section of the entanglement gathering bone 4, and the blade edge 51 has a blade surface 52 inclined outward. In this way, after the entanglement is cut by the blade edge 51, it will move centrifugally outward under the guidance of the inclined blade surface 52, and then be sucked into the dust box 210.

[0052] In order to prevent the cut windings from gathering toward the inner side of the first end cover 2, optionally, please refer to Fig. 9 and Fig.10 In this embodiment, the outer axis size of the winding gathering bone 4 gradually decreases from the end close to the first end cover 2 to the end far from the first end cover 2, and a step surface d is formed on its outer peripheral surface to prevent the winding from moving inward when being cut. In this way, when not cut, the winding will gather and wrap around the end of the winding gathering bone 4 with a smaller outer axis size. After being cut by the cutting member 5, due to the obstruction of the step surface d, the winding will not gather toward the inner side of the first end cover 2. In this way, it is easy to be thrown out under the action of centrifugal force and then sucked into the dust box 210.

[0053] In order to make the anti-winding roller brush 100 have a better effect of guiding the winding, after testing, preferably, please refer to Figure 4 and Figure 8 ; In the present embodiment, the tilt angle α between the cleaning strip 13 and the axis of the roller brush body 1 is 10°; of course, in other embodiments, the tilt angle α between the cleaning strip 13 and the axis of the roller brush body 1 can also be 5°, 7°, 9°, 11°, 13°, 15°, as long as the tilt angle α between the cleaning strip 13 and the axis of the roller brush body 1 is between 5° and 15°. Further, in the present embodiment, the cleaning strip 13 and the roller brush body 1 also have a tilt angle β in the radial direction, that is, the cleaning strip 13 is not arranged along the radial direction of the roller brush body 1. Specifically, the tilt angle β is an acute angle. Preferably, the tilt angle β through the cleaning strip 13 and the roller brush body 1 is preferably between 30° and 50°. This tilt angle enables the anti-entanglement roller brush 100 to have good effects of gathering entanglements, anti-entanglement, and cleaning.

[0054] Optionally, the cleaning strip 13 includes a first scraping strip 131 and a second scraping strip 132, which are alternately arranged in the circumferential direction of the roller brush body 1, and the height of the first scraping strip 131 extending from the surface of the roller brush body 1 is less than the height of the second scraping strip 132 extending from the surface of the roller brush body 1. In this way, the roller brush body 1 can clean particles of different diameters, that is, the first scraping strip 131 is suitable for cleaning large particles of garbage, and the second scraping strip 132 is suitable for cleaning small particles of garbage.

[0055] Optionally, see Figure 2 , Figure 7 and Fig.11 In this embodiment, the anti-winding roller brush 100 also includes a connecting end cap 6, and the end of the connecting end cap 6 away from the driving member is assembled in the cleaning device 1000, and the support shaft 7 is rotatably connected to the connecting end cap 6 through the bearing 8 to realize the rotational assembly of the support shaft 7 and the cleaning device 1000; the cutting member 5 is arranged at the end of the connecting end cap 6 close to the driving member. Specifically, the two cutting members 5 are fixed at the end of the connecting end cap 6 close to the driving member, and the two cutting members 5 are symmetrically arranged relative to the center of the connecting end cap 6. Of course, in other embodiments, the anti-winding roller brush 100 may not include the connecting end cap 6, but the support shaft 7 is directly rotatably connected to the cleaning device 1000 through the bearing 8 to realize the rotational assembly of the support shaft 7 and the cleaning device 1000; at the same time, the cutting member 5 can also be directly fixed in the cleaning device 1000, as long as it can cut off the windings wrapped around the outer periphery of the winding gathering bone position 4 when the roller brush body 1 rotates, and there is no limitation here.

[0056] Optionally, see Figures 6 to 8 In this embodiment, the roller brush body 1 includes a roller brush outer sleeve 12 and a roller brush inner shaft 11. The roller brush outer sleeve 12 is made of rubber, and the cleaning strip 13 is a rubber strip formed integrally with the roller brush outer sleeve 12. The roller brush inner shaft 11 is located in the inner cavity of the roller brush outer sleeve 12. The roller brush body 1 is connected to the driving member through one end of the roller brush inner shaft 11. The inner wall of the roller brush outer sleeve 12 has a spline groove 121. The outer periphery of the roller brush inner shaft 11 has a spline 111 that matches the spline groove 121. The roller brush inner shaft 11 and the roller brush outer shaft are assembled and connected through the spline 111 and the spline groove 121, so as to drive the roller brush outer sleeve 12 to rotate synchronously. Since the roller brush body 1 includes the roller brush outer sleeve 12 and the roller brush inner shaft 11 that are separately arranged, it is easy to manufacture.

[0057] In order to prevent the entanglement or dust from entering the inner cavity of the roller brush outer shaft sleeve 12 through the first end a of the roller brush body 1, causing the entanglement to be entangled in the roller brush inner shaft 11, thereby reducing the rotation efficiency of the roller brush inner shaft 11; preferably, please refer to Figure 7 In this embodiment, the roller brush body 1 further comprises a second end cover 3, which is sleeved on one end of the roller brush inner shaft 11 close to the driving member, and its outer periphery is sealed and connected to the inner wall of the roller brush outer shaft sleeve 12.

[0058] Please refer to Figure 1 and Figure 2On the other hand, this embodiment provides a cleaning device 1000 (not shown in the figure). It should be noted that the cleaning device 1000 can be a cleaning appliance such as a vacuum cleaner or a cleaning robot. The cleaning device 1000 includes: a cleaning device body 200, a driving member assembled in the cleaning device body 200 and the anti-entanglement roller brush 100 as described above, and the anti-entanglement roller brush 100 is transmission-connected to the driving member. Specifically, the cleaning device body 200 has a first installation space (not shown in the figure), a second installation space (not shown in the figure) and a dust box 210; the first installation space is for the anti-entanglement roller brush 100 to be rotatably assembled, and the second installation space is for the driving member to be fixedly assembled; the lower end of the cleaning device body 200 has a cleaning port e connected to the first installation space, so that the roller brush body 1 can clean the surface to be cleaned; the first installation space is connected to the dust box 210, so that dust or entanglements can be sucked into the dust box 210 by the suction device. Since the cleaning device 1000 has all the structures and connection relationships of the anti-entanglement roller brush 100, it has all the advantages of the anti-entanglement roller brush 100, which will not be elaborated here.

[0059] Embodiment 2

[0060] This embodiment is basically the same as the first embodiment, and the only difference is the cross-sectional shape of the outer periphery of the winding gathering bone 4 and the assembly position of the cutting piece 5. Specifically, in this embodiment, the winding gathering bone 4 is sleeve-shaped, and the cross-section of its outer periphery is a regular polygon. The center of the winding gathering bone 4 is assembled by rotation through the support shaft 7 and the cleaning device 1000; the cutting piece 5 and the support shaft 7 are coaxially arranged and located in an annular area with the center of the winding gathering bone 4 as the center, the circumscribed circle of the outer periphery of the winding gathering bone 4 and the inscribed circle of the outer periphery of the winding gathering bone 4. In this way, when the winding gathering bone 4 rotates relative to the cutting piece 5, the cutting piece 5 can also cut off the windings wound around the outer periphery of the winding gathering bone 4, so that they cannot continue to be wound around the outer periphery of the winding gathering bone 4, and then are sucked into the dust box 210 of the cleaning device 1000 under the action of the suction device.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
