[0023] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0028] With the development of intelligent manufacturing technology and communication technology, more and more smart home devices are serving people's lives, bringing great convenience to people's lives. Cleaning equipment, such as vacuum cleaners and sweeping robots, can collect garbage objects on the ground through side brushes, and then use fans to provide air volume to suck out garbage objects, which can semi-automatically or automatically achieve cleaning tasks such as floor cleaning and dust removal. In family life, cleaning equipment gradually replaces people to clean the ground. It can automatically collect and clean food residues and debris on the ground, and suck them out through the suction port, providing convenience for users' lives.

[0029] After long-term research, the inventor of the present application found that the current cleaning equipment uses the side brush to gather and clean the debris and hair around the cleaning equipment, and then absorbs the dust through the suction port of the cleaning equipment. During long-term use, the side brush of the cleaning equipment is often entangled by the hair on the ground when collecting garbage objects on the bottom surface by rotation. As the use time increases, the hair entangled on the side brush increases, which not only affects the cleaning effect of the side brush, but also affects the normal use of the cleaning equipment, and even jams the side brush, shortening the life of the cleaning equipment. During daily maintenance, the hair on the side brush is also difficult to clean, which brings inconvenience to the user. In the related art, a cleaning piece for cleaning the hair on the side brush will be set on the cleaning equipment to continuously clean the hair on the side brush when the side brush collects garbage objects by rotation, but this will affect the normal cleaning work of the side brush, resulting in noise or even jamming. Based on this, the present application proposes the following embodiments to solve the above technical problems.

[0030] The following surface cleaning device embodiments of the present application describe exemplary structures of the cleaning device.

[0031] like Figure 1 As shown, the cleaning device 1 may include a device body 10 , a combing element 20 and a cleaning assembly 30 .

[0032] The cleaning device 1 is used for cleaning. The cleaning device 1 is, for example, a sweeping robot, a cleaning robot or a vacuum cleaner, and may have one or more cleaning functions such as vacuuming, sweeping, mopping and washing. Optionally, the cleaning device 1 may be a self-propelled cleaning device that can walk autonomously or under command control to perform cleaning work.

[0033] The device body 10 is used to walk on the surface to be cleaned so as to collect, suck and store garbage objects. Specifically, the device body 10 can have a cleaning function or a dust collection function, and can also have a cleaning function and a dust collection function at the same time, and can also have other cleaning functions. The device body 10 is used to suck and store garbage objects.

[0034] The combing piece 20 is arranged on the device body 10. The combing piece 20 can be installed on the side of the device body 10 facing the surface to be cleaned by insertion, assembly, combination, etc. The combing piece 20 can be connected to the device body 10 by welding, bonding, and threaded connection. Of course, the combing piece 20 can also be integrally formed with the shell of the device body 10 facing the side of the surface to be cleaned.

[0035] The cleaning assembly 30 is disposed on the device body 10, and includes a brush assembly 310, a rotation drive assembly 320, and a state switching assembly 330. The rotation drive assembly 320 is used to drive the brush assembly 310 to rotate, and the state switching assembly 330 is used to enable the brush assembly 310 to switch between a first state and a second state. Figure 1 As shown, the brush assembly 310 contacts the surface to be cleaned in the first state, and the brush assembly 310 collects garbage objects on the surface to be cleaned by rotating. The brush assembly 310 does not contact the combing member 20 in the first state, so the combing member 20 does not affect the normal cleaning work of the brush assembly 310 on the surface to be cleaned. Figure 2 As shown, in the second state, the brush body assembly 310 is away from the surface to be cleaned and contacts the combing member 20 , so that the combing member 20 cleans the hair entangled on the brush body assembly 310 by the rotation of the brush body assembly 310 .

[0036] The device body 10, the combing member 20 and the cleaning member 30 are provided, wherein the brush body member 310 contacts the surface to be cleaned in the first state so as to clean the surface to be cleaned by rotation, and contacts the combing member 20 in the second state so that the combing member 20 can clean the hair wound around the brush body member 310. The brush body member 310 is provided to have a first state and a second state that can be switched between each other, so as to distinguish the cleaning process of the brush body member 310 on the surface to be cleaned and the cleaning process of the combing member 20 on the brush body member 310, effectively cleaning the hair wound around the brush body member 310 without hindering the normal cleaning work of the brush body member 310, effectively realizing the self-cleaning function of the brush body member 310 of the cleaning device 1, effectively improving the reliability and effectiveness of the cleaning work of the brush body member 310, and effectively improving the applicability of the cleaning device 1.

[0037] Alternatively, if Figure 3 As shown, the brush assembly 310 includes a carrier 311 and at least one brush arm 312, the brush arm 312 has a first end 301 and a second end 302 disposed opposite to each other, and the first end 301 of the brush arm 312 is rotatably connected to the carrier 311. The rotation drive assembly 320 is transmission-connected to the carrier 311, and the rotation drive assembly 320 can drive the carrier 311 to rotate relative to the device body 10 with the preset first rotation axis L1 as the center. The number of brush arms 312 can be, for example, one, two, or three, and of course, other numbers can also be used.

[0038] Alternatively, if Figure 4 and Figure 5As shown, the angle A between the first end 301 and the second end 302 of the brush arm 312 and the first rotation axis L1 in the first state is different from the angle A between the first end 301 and the second end 302 of the brush arm 312 and the first rotation axis L1 in the second state, and compared with the second state, the second end 302 of the brush arm 312 is closer to the device body 10 in the first state. Optionally, the angle A between the first end 301 and the second end 302 of the brush arm 312 and the first rotation axis L1 in the direction of the surface to be cleaned in the first state is smaller than the angle A between the first end 301 and the second end 302 of the brush arm 312 and the first rotation axis L1 in the direction of the surface to be cleaned in the second state, that is, in the first state, the brush arm 312 is lowered, and the second end 302 of the brush arm 312 points to the surface to be cleaned to contact the surface to be cleaned, while in the second state, the brush arm 312 is raised, and the second end 302 of the brush arm 312 points to the device body 10 to stay away from the surface to be cleaned and contact the combing member 20, so that the combing member 20 can clean the hair entangled on the brush arm 312. By setting the angle A between the first end 301 and the second end 302 of the brush arm 312 and the first rotation axis L1 to be different in the first state and the second state, the brush arm 312 can have different positions relative to the surface to be cleaned and the combing member 20 in the first state and the second state, thereby distinguishing the first state in which the brush arm 312 cleans the surface to be cleaned and the second state in which the combing member 20 cleans the hair on the brush arm 312, thereby effectively reducing the possibility of mutual influence and interference between the two. While effectively improving the reliability and stability of the cleaning device 1 in cleaning the surface to be cleaned, it is beneficial to improve the reliability and stability of the combing member 20 cleaning the brush arm 312, effectively realizing the self-cleaning function of the cleaning device 1, and helping to improve the applicability of the cleaning device 1.

[0039] Alternatively, if Figures 3 to 5As shown, the brush arm 312 is configured to rotate relative to the carrier 311 with the preset second rotation axis L2 as the center under the action of the state switching component 330, and the first rotation axis L1 and the second rotation axis L2 are arranged crosswise, that is, on the basis of the carrier 311 driving the brush arm 312 to rotate around the first rotation axis L1, the brush arm 312 can rotate relative to the carrier 311 around the second rotation axis L2. Further, in the first state, the brush arm 312 rotates relative to the carrier 311 to achieve lowering, and the second end 302 of the brush arm 312 points to the surface to be cleaned to contact the surface to be cleaned, while in the second state, the brush arm 312 rotates relative to the carrier 311 to achieve lifting, and the second end 302 of the brush arm 312 points to the device body 10 to stay away from the surface to be cleaned and contact the combing member 20, so that the combing member 20 can clean the hair entangled on the brush arm 312. The brush arm 312 is equivalent to the rotation of the supporting member 311 so that the brush arm 312 contacts the surface to be cleaned in the first state and contacts the combing member 20 in the second state. The structure is simple, and the switching is fast and convenient, which effectively improves the efficiency of the brush arm 312 in changing the relative position when switching between the first state and the second state, thereby effectively improving the efficiency of the brush body assembly 310 in switching between the first state and the second state.

[0040] Alternatively, if Figure 4 and Figure 5 As shown, the brush body assembly 310 further includes a bristle portion 313, which is disposed at the second end 302 of the brush arm 312. The bristle portion 313 rotates synchronously with the brush arm 312, that is, the bristle portion 313 can rotate along with the brush arm 312 around the first rotation axis L1 when the support member 311 drives the brush arm 312 to rotate around the first rotation axis L1, and can rotate along with the brush arm 312 around the second rotation axis L2 relative to the support member 311, so as to realize the lifting and lowering of the bristle portion 313, and further realize the contact of the bristle portion 313 with the surface to be cleaned and the combing member 20 in the first state and the second state respectively.

[0041] Alternatively, if Figure 1 and Figure 4 As shown, in the first state, the rotation drive assembly 320 drives the carrier 311 to rotate around the first rotation axis L1 along the second direction F2, thereby driving the brush arm 312 and the bristle portion 313 to rotate around the first rotation axis L1 along the second direction F2, and the bristle portion 313 contacts the surface to be cleaned and collects and cleans the garbage objects on the surface to be cleaned. Figure 2 and Figure 5As shown, the rotation drive assembly 320 drives the carrier 311 to rotate around the first rotation axis L1 along the first direction F1 in the second state, thereby driving the brush arm 312 and the bristle portion 313 to rotate around the first rotation axis L1 along the first direction F1, and the bristle portion 313 cyclically contacts the combing member 20. By arranging the bristle portion 313 to rotate along the second direction F2 around the first rotation axis L1 when contacting the surface to be cleaned in the first state, and to rotate along the first direction F1 around the first rotation axis L1 when contacting the combing member 20 in the second state, the second direction F2 and the first direction F1 are in opposite directions, so that the hair on the surface to be cleaned is rotated and entangled on the bristle portion 313 rotating along the second direction F2, and the hair on the bristle portion 313 rotating along the first direction F1 opposite to the second direction F2 is combed and separated by the combing member 20, thereby effectively improving the efficiency of cleaning the hair on the bristle portion 313, effectively reducing the possibility of further entanglement of the hair on the bristle portion 313 due to the contact between the combing member 20 and the bristle portion 313, and effectively improving the effectiveness and reliability of the combing work of the combing member 20.

[0042] Alternatively, if Figure 6 As shown, the combing member 20 is provided with a plurality of comb teeth 210 spaced apart from each other, and the rotary drive assembly 320 drives the carrier 311 to rotate around the first rotation axis L1 along the first direction F1 in the second state, thereby driving the brush arm 312 and the bristle portion 313 to rotate around the first rotation axis L1 along the first direction F1 and contact the combing member 20, so that the rotary drive assembly 320 drives the bristle portion 313 to circulate through the comb tooth gaps 201 between the plurality of comb teeth 210 in the second state. The hair on the bristle portion 313 is cleaned by the plurality of comb teeth 210, which effectively improves the efficiency of cleaning the hair on the bristle portion 313, and effectively improves the effectiveness and reliability of the combing work of the combing member 20.

[0043] Alternatively, if Figure 7 As shown, the state switching component 330 is configured to be able to push or pull the brush arm 312 along the first rotation axis L1 so that the brush arm 312 rotates relative to the carrier 311. Specifically, while the rotation drive component 320 drives the carrier 311 to rotate around the first rotation axis L1 to drive the brush arm 312 and the bristle portion 313 to rotate around the first rotation axis L1, the state switching component 330 pushes or pulls the brush arm 312 along the first rotation axis L1 so that the brush arm 312 and the bristle portion 313 rotate around the second rotation axis L2 relative to the carrier 311 to achieve switching between the first state and the second state. The structure is simple and effective, the structural reliability is high, and the switching efficiency between the first state and the second state is effectively improved.

[0044] Alternatively, if Figure 7As shown, the state switching component 330 is configured to be linked with the rotation drive component 320, and when the rotation drive component 320 rotates along the first direction F1, the brush body component 310 can be switched from the first state to the second state, and when the rotation drive component 320 rotates along the second direction F2, the brush body component 310 can be switched from the second state to the first state. Through the linkage between the rotation drive component 320 and the state switching component 330, the switching between the first state and the second state is achieved by switching the rotation direction of the brush body component 310, which is simple to operate and highly effective, and effectively improves the switching efficiency between the first state and the second state.

[0045] Alternatively, if Figure 7 As shown, the state switching assembly 330 is configured to approach and push the brush arm 312 to rotate relative to the carrier 311 along the first rotation axis L1 when the rotary drive assembly 320 rotates along the first direction F1, thereby switching the brush body assembly 310 from the first state to the second state, specifically, the brush arm 312 is lifted up to contact the combing member 20, and when the rotary drive assembly 320 rotates along the second direction F2, it moves away from the brush arm 312 in the opposite direction along the first rotation axis L1. The brush body assembly 310 switches from the second state to the first state under the action of its own gravity or a preset biasing force, specifically, the brush arm 312 is lowered to contact the surface to be cleaned. In some embodiments, the state switching assembly 330 includes a slider 335, which is configured to approach and push the brush arm 312 to rotate relative to the carrier 311 along the first rotation axis L1 when the rotary drive assembly 320 rotates along the first direction F1, thereby switching the brush body assembly 310 from the first state to the second state. In some embodiments, a spring, torsion spring or other elastic member is provided in the brush assembly 310 to provide a biasing force, so that the brush assembly 310 is switched from the second state to the first state under the action of a preset biasing force. In other embodiments, a magnetic member is provided in the brush assembly 310, and the magnetic attraction provided by the magnetic member is used as a biasing force, so that the brush assembly 310 is switched from the second state to the first state under the action of a preset biasing force.

[0046] Alternatively, if Figure 7 As shown, the rotation drive assembly 320 includes a power source 321, a transmission assembly 322 and a rotating member 323. The rotating member 323 is rotatably supported on the device body 10, and the bearing member 311 is arranged on the rotating member 323. The power source 321 drives the rotating member 323 to rotate around the first rotation axis L1 through the transmission assembly 322. The power source 321 can be a motor, such as a DC motor or an AC motor. The transmission assembly 322 can include at least one transmission gear, and the outer periphery of the rotating member 323 is provided with a gear meshing with the transmission gear. The power source 321 drives the transmission gear to rotate, so as to drive the rotating member 323 to rotate.

[0047] Alternatively, if Figure 7 As shown, the state switching assembly 330 includes a first threaded member 331 and a second threaded member 332. The first threaded member 331 is coaxially arranged with the rotating member 323 and rotates synchronously with the rotating member 323. The second threaded member 332 cooperates with the first threaded member 331 so that the first threaded member 331 translates along the first rotation axis L1 relative to the rotating member 323 while rotating. The first threaded member 331 translates along the first rotation axis L1 relative to the rotating member 323 to achieve switching between the first state and the second state. The operation is simple and effective, and the switching efficiency between the first state and the second state is effectively improved.

[0048] Alternatively, if Figure 7 As shown, the first threaded member 331 is provided with a threaded segment 3311 matching with the second threaded member 332, and the state switching assembly 330 further includes a biasing member 333. The threaded segment 3311 is configured to disengage from the threaded engagement with the second threaded member 332 after the rotation drive assembly 320 rotates a predetermined angle along the second direction F2, so that the first threaded member 331 rotates only with the rotating member 323, and the threaded segment 3311 is further configured to restore the threaded engagement with the second threaded member 332 under the biasing action of the biasing member 333 when the rotation drive assembly 320 rotates along the first direction F1. The biasing member 333 can be, for example, an elastic member such as a spring. When the brush body assembly 310 is in the first state, the biasing member 333 is elastically compressed, and when the brush body assembly 310 is switched to the second state, the biasing member 333 is elastically reset so that the threaded segment 3311 restores the threaded engagement with the second threaded member 332 under the biasing action of the biasing member 333. In some embodiments, the biasing member 333 and the first threaded member 331 are in indirect contact via the spherical member 334 rather than direct contact, thereby converting the sliding friction between the biasing member 333 and the first threaded member 331 into rolling friction, effectively reducing the friction force, facilitating the rotation of the first threaded member 331, reducing the wear of the first threaded member 331, increasing the service life of the first threaded member 331 and the biasing member 333, and increasing the working reliability of the first threaded member 331.

[0049] The switching of the brush body assembly 310 between the first state and the second state is described in detail below.

[0050] When the brush body assembly 310 is in the first state, the rotation drive assembly 320 drives the rotating member 323 to rotate along the second direction F2 around the first rotation axis L1, and the supporting member 311 and the first threaded member 331 rotate around the first rotation axis L1 along the second direction F2 driven by the rotating member 323. The supporting member 311 drives the brush arm 312 to rotate, and the brush arm 312 is in a lowered state relative to the supporting member 311, so that the bristle part 313 contacts the surface to be cleaned, so as to collect and clean the garbage objects on the surface to be cleaned through rotation.

[0051] When the brush body assembly 310 switches from the first state to the second state, the rotation driving assembly 320 drives the rotating member 323 to switch from rotating around the first rotation axis L1 along the second direction F2 to rotating along the first direction F1. The supporting member 311 and the first threaded member 331 rotate around the first rotation axis L1 along the first direction F1 driven by the rotating member 323. The threaded segment 3311 of the first threaded member 331 resumes the threaded cooperation with the second threaded member 332 under the biasing action of the biasing member 333, so that the first threaded member 331 translates along the first rotation axis L1 relative to the rotating member 323 toward the supporting member 311 while rotating, thereby pushing the slider 335 to approach the brush arm 312, so that the slider 335 pushes the brush arm 312 to rotate around the second rotation axis L2 relative to the supporting member 311, thereby switching the brush body assembly 310 from the first state to the second state, and the brush arm 312 is lifted relative to the supporting member 311, so that the bristle portion 313 contacts the combing member 20.

[0052] When the brush body assembly 310 is in the second state, the rotating drive assembly 320 drives the rotating member 323 to rotate along the first direction F1 around the first rotation axis L1, and the supporting member 311 rotates along the first direction F1 around the first rotation axis L1 driven by the rotating member 323. The supporting member 311 continuously drives the brush arm 312 to rotate along the first rotation axis L1 along the first direction F1, and the brush arm 312 is in an upward state relative to the supporting member 311, so that the bristle part 313 contacts the combing part 20, and then the bristle part 313 circulates through the comb tooth gap 201 between the multiple comb teeth 210 in sequence, and the hair on the bristle part 313 is cleaned by the multiple comb teeth 210.

[0053] When the brush body assembly 310 is switched from the second state to the first state, the rotation drive assembly 320 drives the rotating member 323 to switch from rotating around the first rotation axis L1 along the first direction F1 to rotating along the second direction F2. The supporting member 311 and the first threaded member 331 rotate around the first rotation axis L1 along the second direction F2 driven by the rotating member 323. The threaded segment 3311 of the first threaded member 331 disengages from the threaded engagement with the second threaded member 332 after rotating by a predetermined angle along the second direction F2, so that the first threaded member 331 translates relative to the rotating member 323 along the first rotation axis L1 away from the supporting member 311 while rotating. The brush arm 312 rotates relative to the supporting member 311 around the second rotation axis L2 under the action of its own gravity or a preset bias force to be lowered, thereby switching the brush body assembly 310 from the second state to the first state, and the bristle portion 313 resumes contact with the surface to be cleaned, so as to collect and clean garbage objects on the surface to be cleaned by rotation.

[0054] In summary, by setting the device main body 10, the combing element 20 and the cleaning component 30, wherein the cleaning component 30 includes a brush body component 310, a rotation drive component 320 and a state switching component 330, the brush body component 310 has a first state and a second state, the rotation drive component 320 is used to drive the brush body component 310 to rotate, and the state switching component 330 is used to realize the switching between the first state and the second state. The brush body component 310 contacts the surface to be cleaned in the first state to clean the surface to be cleaned by rotation, and contacts the combing element 20 in the second state so that the combing element 20 can clean the hair wrapped around the brush body component 310. By configuring the brush body assembly 310 to have a first state and a second state that can be switched between each other, the cleaning process of the brush body assembly 310 on the surface to be cleaned and the cleaning process of the brush body assembly 310 by the combing member 20 can be distinguished, while the hair entangled on the brush body assembly 310 is effectively cleaned without hindering the normal cleaning work of the brush body assembly 310, the self-cleaning function of the brush body assembly 310 of the cleaning device 1 is effectively realized, the reliability and effectiveness of the cleaning work of the brush body assembly 310 are effectively improved, and the applicability of the cleaning device 1 is effectively improved.
