[0029] To enable those skilled in the art to better understand the technical solutions in the embodiments of this application, and to make the above-mentioned objectives, features, and advantages of the embodiments of this application more apparent, the technical solutions in the embodiments of this application will be further described in detail below with reference to the accompanying drawings. Unless otherwise specified, the following embodiments and features in the embodiments can be combined with each other.
[0030] See Figures 1 to 3 As shown, this application provides a cleaning device, including a device body 10 and a roller brush structure 20. The roller brush structure 20 is disposed on the device body 10 and can be detachably disposed on the device body 10 for easy disassembly, replacement, and cleaning. Optionally, the roller brush structure 20 is disposed at the bottom of the device body 10, such as... Figure 2 As shown. Cleaning equipment can include sweepers, floor scrubbers, vacuum cleaners, or mite removers, etc. Figure 1 Taking a floor scrubber as an example, the cleaning equipment may also include a charging base 30 for charging the main body 10, and the main body 10 may also be equipped with a clean water tank and a wastewater tank. When the cleaning equipment is a vacuum cleaner, it may also include a handheld component and a rigid hose.
[0031] like Figure 3As shown, the rolling brush structure 20 comprises a housing 21 and two rolling brushes 22. The two rolling brushes 22 are arranged side by side along the rotation axis X in the housing 21, and can rotate around the rotation axis X relative to the housing 21, and move in the same direction or in the opposite direction along the extension direction of the rotation axis X. It should be noted that the rolling brush 22 can rotate and move along the extension direction of the rotation axis X at the same time, or rotate without moving along the extension direction of the rotation axis X, or move along the extension direction of the rotation axis X without rotating, which can be set according to actual needs. In this way, the rolling brush structure 20 comprises two parallel rolling brushes 22, and the two rolling brushes 22 can move in the same direction or in the opposite direction, which can pull the entangled hair on the rolling brush 22, and is beneficial to suck the entangled hair into the dust box of the cleaning device, thereby improving the cleaning efficiency of the cleaning device and improving the user experience.
[0032] In some optional embodiments, the two rolling brushes 22 have a first position state and a second position state along the rotation axis X. As shown in Figure 3 As shown, when the two rolling brushes 22 move in the opposite direction along the rotation axis X to the first limit position, the two rolling brushes are in the first position state, and in the first position state, the distance between the adjacent ends of the two rolling brushes 22 is a first distance. As shown in Figure 4 As shown, when the two rolling brushes move in the same direction along the extension direction of the rotation axis X to the second limit position, the two rolling brushes are in the second position state, and in the second position state, the distance between the adjacent ends of the two rolling brushes 22 is a second distance, and the second distance is greater than the first distance. In this way, the two rolling brushes 22 can better pull the entangled hair on the rolling brush through repeated relative movement along the extension direction of the rotation axis X.
[0033] As shown in Figure 4 In some optional embodiments, in the projection plane parallel to the rotation axis X, the two rolling brushes 22 at least partially overlap along the adjacent ends of the rotation axis X, and the overlapping part is as shown in Figure 4 As shown in A of FIG. 8, the two rolling brushes 22 can overlap and cover the cleaning area in the projection perpendicular to the rotation axis X, so that the cleaning range is larger and the cleaning effect is better.
[0034] In the embodiment, the two brushes 22 are arranged along the extension direction of the rotation axis X, and the end faces of the two brushes 22 adjacent to the rotation axis X are both inclined with respect to the rotation axis X and parallel to each other. In this way, the two brushes 22 can form a partial overlap in the projection plane parallel to the rotation axis X. In other embodiments, the two brushes 22 can also be arranged in staggered positive L shape and negative L shape, and also can form a partial overlap in the projection plane parallel to the rotation axis X. Alternatively, the included angle between the end face of the two brushes 22 adjacent to the rotation axis X and the rotation axis X ranges from 30° to 60°, which can be adjusted according to actual needs.
[0035] In the case that the two brushes 22 form a partial overlap in the projection plane parallel to the rotation axis X, the two brushes 22 rotate around the rotation axis X at the same frequency and in the same direction with respect to the shell 21, so as to avoid the overlap of the two brushes 22 from colliding with each other during rotation.
[0036] Referring to Figure 5 In some optional embodiments, the two brushes 22 do not overlap in the projection plane parallel to the rotation axis X, that is, the two brushes 22 do not form an overlap in the projection plane parallel to the rotation axis X. The two brushes 22 can rotate around the rotation axis X at the same frequency and in the same direction, at different frequencies and in the same direction, at the same frequency and in opposite directions, or at different frequencies and in opposite directions with respect to the shell 21.
[0037] When the two brushes 22 rotate at the same frequency and in the same direction, the relative movement of the two brushes 22 along the extension direction of the rotation axis X can pull the hair wound on the brushes. On this basis, when the two brushes 22 rotate at different frequencies and in the same direction, at the same frequency and in opposite directions, or at different frequencies and in opposite directions, the hair wound on the two brushes at the same time can be further pulled during rotation, so as to achieve a better cleaning effect.
[0038] In the embodiment, the two brushes 22 are arranged along the extension direction of the rotation axis X, and the end faces of the two brushes 22 adjacent to the rotation axis X are both perpendicular with respect to the rotation axis X and parallel to each other. In this way, the two brushes 22 can not only ensure that there is no overlap between them, but also can avoid collision during rotation.
[0039] In some optional embodiments, when the two brushes 22 move in the same direction or in opposite directions along the extension direction of the rotation axis X, the distance between the two brushes 22 adjacent to the rotation axis X ranges from 2 mm to 6 mm. The distance can refer to the distance between the two parallel end faces of the two brushes 22 adjacent to the rotation axis X.
[0040] It can be understood that when the two rolling brushes 22 move to the limit position in opposite directions, the distance between the two rolling brushes 22 is 6mm. When the two rolling brushes 22 move to the limit position in the same direction, the distance between the two rolling brushes 22 is 2mm. Alternatively, when the two rolling brushes 22 move to the limit position in the same direction, the distance between the two rolling brushes 22 at the closest position is in the range of 2mm-6mm. The specific value of the distance can be set according to the user's needs.
[0041] Referring to Figure 6 As shown in some optional embodiments, the rolling brush structure can further include a support assembly 40, a first driving member 41 and a second driving member 42. The first driving member 41 is arranged in the housing 21, the support assembly 40 is connected with the first driving member 41, and the second driving member 42 is arranged in the support assembly 40. The rolling brush 22 is connected with the second driving member 42. The first driving member 41 is used to drive the support assembly 40 to move along the extension direction of the rotation axis X, and the second driving member 42 is used to drive the rolling brush 22 to rotate around the rotation axis X. In this way, the first driving member 41 and the second driving member 42 respectively drive the rolling brush 22 to rotate around the rotation axis X and to move relatively along the extension direction of the rotation axis X. The control accuracy is better.
[0042] Further, the first driving member 41 includes a first motor, a screw rod 411 and a nut 412. The first motor is arranged in the housing 21, the screw rod 411 is connected with the first motor, and the nut 412 is sleeved on the screw rod 411 and connected with the support assembly 40. The support assembly 40 can include a first support 401 and a second support 402. The nut 412 is connected with the first support 401, the first support 401 is connected with the second support 402, and the second driving member 42 is arranged in the second support 402. The second driving member 42 can include a second motor, and the second motor is arranged in the second support 402. The rolling brush 22 can be connected with the second driving member 42 through an intermediate transmission member (not shown) arranged in the second support 402. Alternatively, the rolling brush 22 can be directly connected with the second driving member 42.
[0043] The axial direction of the screw rod 411 is along the rotation axis X. In this way, the first motor drives the screw rod 411 to rotate around the axial direction, the nut 412 is threadedly matched with the screw rod 411, and the relative position along the screw rod 411 is changed, so as to drive the nut 412 and the support assembly 40 to move along the extension direction of the rotation axis X relative to the screw rod 411, thereby driving the rolling brush 22 to move along the extension direction of the rotation axis X.
[0044] In addition to the cooperation of the screw rod and the nut described above, the first driving member 41 can be connected with a sliding member, the sliding member is connected with the support assembly 40, and the first driving member 41 drives the sliding member to move along the extension direction of the rotation axis X, so as to drive the support assembly 40 and the roller brush 22 to move along the extension direction of the rotation axis X.
[0045] Alternatively, an elastic member and a magnet can also be provided, the elastic member is connected with the first driving member 41, the magnet is connected with the support assembly 40, the first driving member 41 provides electricity to enable the elastic member to generate a magnetic field as a magnetic coil, and the magnet generates an attractive or repulsive force, thereby driving the support assembly 40 and the roller brush 22 to move along the extension direction of the rotation axis X.
[0046] The two side ends of the support assembly 40 are provided with a space for accommodating the roller brushes 22 when the roller brushes 22 move away from each other, i.e., move in opposite directions, so as to provide an accommodation space, and the end portions do not leave a blank cleaning area in both states.
[0047] In some optional embodiments, the screw rod 411 is provided with a first limiting member and a second limiting member along the rotation axis X, and the nut 412 is arranged between the first limiting member and the second limiting member.
[0048] In this way, when the nut 412 moves along the extension direction of the rotation axis X to abut against the first limiting member, the two roller brushes 22 move in the same direction along the extension direction of the rotation axis X to a first limit position. When the nut 412 moves along the extension direction of the rotation axis X to abut against the second limiting member, the two roller brushes 22 move in opposite directions along the extension direction of the rotation axis X to a second limit position. The distance between the first limiting member and the second limiting member determines the stroke distance of the roller brushes 22 along the rotation axis X, and the distance between the two adjacent ends of the two roller brushes 22 along the rotation axis.
[0049] In some optional embodiments, the shell 21 is provided with a dust collecting port 211, and the two roller brushes 22 are arranged corresponding to the dust collecting port 211. It can be understood that a dust collecting chamber can be arranged on the device body 10 and is in communication with the dust collecting port 211, so that the garbage cleaned by the roller brushes 22 can be sent into the dust collecting chamber through the dust collecting port 211 for collection.
[0050] It should be noted that the technical solutions or technical features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of the present application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
