For those skilled in the art, the specific meaning of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0098] With the development of technology, the function of cleaning equipment is more and more powerful, and the types of dirt that can be cleaned are more and more. In the related art, the equipment is provided with a side brush for sweeping the ground.

[0099] However, when the side brush is used to clean liquid dirt such as sewage, the sewage may be spread or smoothed when the side brush sweeps over the sewage due to the viscosity of the sewage, thereby increasing the area of the sewage and increasing the cleaning difficulty. In addition, in the long-term use process, when the side brush of the cleaning equipment collects the garbage objects on the ground by rotating, it is often entangled by the hair on the ground. With the increase of use time, 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 causes the side brush to be stuck, thereby shortening the service life of the cleaning equipment.

[0100] If such problems occur, the side brush can be lifted off the ground, and the hair and other flexible objects can be cleaned by using the cleaning equipment or other components of the cleaning equipment, and the normal cleaning work of the side brush will not be affected, which will improve the cleaning efficiency and the cleanliness of the ground.

[0101] Please refer to FIG. 1, the embodiment of the present application provides a cleaning equipment 3000. The cleaning equipment 3000 comprises an equipment main body 2000 and a side brush mechanism 100. The side brush mechanism 100 is arranged on the equipment main body 2000.

The cleaning equipment 3000 is, for example, a sweeping robot, a cleaning robot or a dust collector, etc., which can have one or more cleaning functions such as dust collection, sweeping, mopping and washing. Optionally, the cleaning equipment 3000 can be a self-walking cleaning equipment 3000, which can walk autonomously or under the instruction control, and then perform the cleaning work.

[0103] The equipment main body 2000 is used for walking on the surface to be cleaned, and can also collect, suck and store garbage objects. Specifically, the equipment main body 2000 can have a sweeping function or a dust collection function, of course, can have both sweeping and dust collection functions, and can also have other cleaning functions. The equipment main body 2000 is used for sucking and storing garbage objects.

[0104] The device body 2000 can be provided with a fan for providing an air volume, for example, an amount of air flowing through the fan per unit time. The greater the air volume, the more air containing garbage objects is sucked into the cleaning device 3000 per unit time. Under the action of the air volume provided by the fan and directed to the inside of the device body 2000, the cleaning device 3000 will suck in air containing garbage objects, thereby achieving the purpose of cleaning. The device body 2000 can also include a dust box, which can be installed in the device body 2000 by insertion, assembly, combination, or the like. The dust box can be used to store dust, debris, and other garbage objects. The device body 2000 can also include a walking assembly, which can enable the cleaning device 3000 to have a movable function. The walking assembly can include a driving mechanism and a rolling wheel mechanism. The driving mechanism is used to drive the rolling wheel mechanism to rotate, so that the cleaning device 3000 can move on the working surface. The driving mechanism is, for example, a motor. The device body 2000 can also include a sensing assembly, which is used to realize one or more corresponding functions, such as infrared function, collision sensing function, etc., and can be used to realize functions such as obstacle avoidance, navigation, and recharging. The device body 2000 can also include a control circuit, which can be coupled to the walking assembly, the side brush mechanism 100, the fan, and the sensing assembly, etc., and can be used to control the operation of the above-mentioned assemblies to realize corresponding operations. The control circuit can be an MCU or a circuit board including an MCU, which serves as the processing hub of the cleaning device 3000.

[0105] The side brush mechanism 100 is arranged on the device body 2000 and is used to contact the surface to be cleaned to gather and clean garbage objects on the surface to be cleaned by rotating.

[0106] The side brush mechanism 100 includes a driving assembly 12 and a side brush assembly 14.

This reduces the occurrence of situations where the side brush 21 is entangled with hair or contaminated with sewage during cleaning, thereby improving the use adaptability of the cleaning device.

[0108] Please refer to FIGS. 2 to 4. The embodiments of the present application provide a cleaning device 3000. The side brush mechanism 100 of the cleaning device 3000 further includes a mounting seat 10. The driving assembly 12 is mounted on the mounting seat 10, and the side brush assembly 14 is movably mounted on the mounting seat 10.

[0109] The driving assembly 12 is configured to drive the brush assembly 14 to move between the first position and the second position, in the case that the brush assembly 14 is located at the first position, the brush 21 is in contact with the ground, in the case that the brush assembly 14 is located at the second position, the brush 21 is separated from the ground.

[0110] The brush mechanism 100 described above, the brush 21 can be in contact with the ground to clean the ground when the brush 21 is in the first position, and the brush 21 is separated from the ground when the brush 21 is in the second position, so that the brush 21 can avoid liquid dirt such as sewage, avoid increasing the dirt area, or use the brush 21 in the second position to contact other parts of the cleaning device 3000 to comb or cut flexible objects such as hair, so that the cleaning device 3000 can be used normally.

[0111] Specifically, the brush mechanism 100 is used to be installed at the bottom of the device main body 2000 or installed at the bottom of the device main body 2000 by other means. For example, the brush mechanism 100 is installed on a swing device installed at the bottom of the device main body 2000, so that the brush 21 of the brush mechanism 100 has a swing motion when rotating, so that the brush mechanism 100 can better clean the ground. The brush mechanism 100 cleans the ground by driving the brush 21 to rotate. The driving assembly 12 and the brush assembly 14 are installed in the mounting seat 10, the driving assembly 12 is used to drive the brush assembly 14 to move between the first position and the second position, in the case that the brush assembly 14 is located at the first position, the brush 21 is in contact with the ground, and the ground can be cleaned. In the case that the brush assembly 14 is located at the second position, the brush 21 is separated from the ground, and can avoid liquid dirt such as sewage on the ground.

[0112] In some embodiments, the driving assembly 12 is configured to drive the brush assembly 14 to rotate in a first direction to make the brush assembly 14 located at the first position, and drive the brush assembly 14 to rotate in a second direction to make the brush assembly 14 located at the second position.

[0113] In this way, the driving assembly 12 drives the brush assembly 14 to rotate to realize the contact or separation of the brush 21 with the ground.

[0114] Specifically, the first direction and the second direction are two opposite directions of the driving assembly 12. For example, the driving assembly 12 includes a motor, the first direction is the forward rotation direction of the motor, and the second direction is the reverse rotation direction of the motor. Or, the first direction is the reverse rotation direction of the motor, and the second direction is the forward rotation direction of the motor. As shown in FIG. 2, the first direction is the direction shown by R1, and the second direction is the direction shown by R2.

[0115] The driving assembly 12 drives the brush assembly 14 to rotate in the first direction to position the brush assembly 14 at the first position, and drives the brush assembly 14 to rotate in the second direction to position the brush assembly 14 at the second position. Thus, when the brush assembly 14 is positioned at the first position, the brush 21 contacts the ground and cleans the ground. When the brush assembly 14 is positioned at the second position, the brush 21 is spaced from the ground and avoids liquid dirt such as water on the ground.

[0116] In some embodiments, the brush assembly 14 further comprises a lifting assembly, the brush 21 is movably mounted on the lifting assembly, the lifting assembly is movably mounted on the mounting base 10, and the lifting assembly is configured to rotate together with the brush 21 when the brush 21 rotates in the first direction, and stop rotating when the brush 21 rotates in the second direction, so that the brush 21 moves away from the ground relative to the lifting assembly to be spaced from the ground.

[0117] Thus, the brush 21 can be moved away from the ground relative to the lifting assembly by the lifting assembly when the brush 21 rotates in the second direction.

[0118] Specifically, the driving assembly 12 drives the brush assembly 14 to move between the first position and the second position to realize the contact or spacing of the brush 21 with the ground. When the brush 21 rotates in the first direction, the lifting assembly can rotate together with the brush 21, and the brush 21 contacts the ground to clean the ground. When the brush 21 rotates in the second direction, the lifting assembly stops rotating, and the brush 21 moves away from the ground relative to the lifting assembly to be spaced from the ground, thereby avoiding spreading of the water when the brush 21 sweeps the water.

[0119] Referring to FIGS. 2-4 and 8, in some embodiments, the lifting assembly comprises a bottom cover 18 and a floating cover 20, the brush 21 is movably mounted between the bottom cover 18 and the floating cover 20, the bottom cover 18 is provided with a lifting portion 22, the floating cover 20 is provided with a recessed portion 24, and the lifting portion 22 and the recessed portion 24 define a track 26 for the movement of the brush 21 when the floating cover 20 is mounted on the bottom cover 18. When the brush 21 is driven by the driving assembly 12 to rotate in the second direction, the brush 21 moves along the track 26 to be spaced from the ground.

[0120] Thus, the brush 21 can move upward along the track 26 when rotating in the second direction, so as to be spaced from the ground.

[0121] Specifically, as shown in FIG. 2, FIG. 7 and FIG. 12, the lifting assembly includes a bottom cover 18 and a floating cover 20, and the edge brush 21 is arranged between the bottom cover 18 and the floating cover 20. The bottom cover 18 is provided with a lifting portion 22, and the floating cover 20 is provided with a recessed portion 24, and the lifting portion 22 and the recessed portion 24 define a track 26 for the movement of the edge brush 21. When the driving assembly 12 drives the edge brush assembly 14 to rotate in the second direction, the bottom cover 18 and the floating cover 20 are fixed and do not rotate, so that the edge brush 21 moves relative to the bottom cover 18 and the floating cover 20, and the edge brush 21 moves along the track 26 between the bottom cover 18 and the floating cover 20, so that the edge brush 21 is spaced from the ground.

[0122] When the edge brush 21 moves upward along the track 26 between the bottom cover 18 and the floating cover 20 in the second direction, the lowest position of the edge brush 21 can be lifted by 4mm-10mm relative to the ground. For example, when the edge brush 21 is in the second position, the distance between the lowest position of the edge brush 21 and the ground can be 4mm, 5mm, 6mm, 7mm, 8mm, 9mm or 10mm, or any value within the range [4mm, 10mm]. In this way, the cleaning surface can be completely separated from the ground.

[0123] Please refer to FIG. 3 and FIG. 4, in some embodiments, the lifting assembly includes a first transmission member, which includes an output shaft 30 and a one-way bearing 34, one end of the output shaft 30 is fixedly connected with a fixed member, the other end of the output shaft 30 is fixedly connected with the one-way bearing 34, and the one-way bearing 34 is configured to rotate in the first direction and not rotate in the second direction.

[0124] In this way, the one-way bearing 34 can be used to realize that the lifting assembly rotates in the first direction and does not rotate in the second direction.

[0125] Specifically, the main function of the one-way bearing 34 is that it can rotate freely in one direction, and is locked or has a large resistance in the other direction.

[0126] The driving assembly 12 is in transmission connection with the edge brush 21, and drives the edge brush 21 to drive the whole edge brush assembly 14 to move. The driving assembly 12 is in transmission connection with the edge brush 21. The edge brush 21 is arranged between the bottom cover 18 and the floating cover 20, and the bottom cover 18 and the floating cover 20 are fixedly connected with the first transmission member.

[0127] When the edge brush 21 moves in the first direction, the bottom cover 18 and the floating cover 20 move together with the edge brush 21, and when the edge brush 21 moves in the second direction, the bottom cover 18 and the floating cover 20 do not rotate due to the action of the one-way bearing 34. In this way, the edge brush 21 can rise along the track 26 between the bottom cover 18 and the floating cover 20, so as to be separated from the ground.

[0128] Optionally, the first transmission member further comprises a circlip 35 clamped on the output shaft 30, which can limit the displacement of the output shaft 30 in the axial direction.

[0129] Optionally, the first transmission member can further comprise some specially designed gear structure, for example, a ratchet mechanism, which comprises a fixed ratchet and a rotating member with a pawl, the pawl can push the ratchet to rotate in one direction, and be clamped by the ratchet in the other direction, so as to achieve the effect of one-way transmission.

[0130] Optionally, the first transmission member can further comprise an electromagnetic clutch, the engagement and separation of which are controlled by electromagnetic force, so as to achieve the effect of one-way transmission.

[0131] Referring to FIGS. 3, 4 and 9, in some embodiments, the mounting base 10 is provided with a receiving cavity 36, the floating cover 20, the bristle brush 21 and the bottom cover 18 are sequentially arranged in the receiving cavity 36, the bottom surface of the receiving cavity 36 is provided with a first limiting portion 38, the top surface of the floating cover 20 is provided with a second limiting portion 40, in the case that the bristle brush 21 moves along the track 26, the bristle brush 21 lifts up the floating cover 20, the first limiting portion 38 and the second limiting portion 40 are in contact with each other, in the case that the first limiting portion 38 and the second limiting portion 40 are in contact with each other and the bristle brush 21 rotates in the first direction, the floating cover 20 and the bottom cover 18 do not rotate.

[0132] In this way, in the case that the bristle brush 21 rotates in the first direction, the floating cover 20 and the bottom cover 18 can be fixed and not rotated by the first limiting portion 38 and the second limiting portion 40, so that the bristle brush 21 moves along the track 26 until the bristle brush assembly 14 is in the first position.

[0133] Specifically, the mounting base 10 is provided with the receiving cavity 36 on the side facing the bristle brush 21, the floating cover 20, the bristle brush 21 and the bottom cover 18 are sequentially arranged in the receiving cavity 36, and the floating cover 20 is closer to the bottom surface of the receiving cavity 36.

[0134] The bottom surface of the receiving cavity 36 is provided with the first limiting portion 38, the top surface of the floating cover 20 is provided with the second limiting portion 40, the bristle brush 21 moves along the track 26 and rises, and the floating cover 20 is lifted up until the first limiting portion 38 and the second limiting portion 40 are in contact with each other.

[0135] When the first limiting portion 38 and the second limiting portion 40 are in contact with each other, if the driving assembly 12 drives the bristle brush 21 to rotate in the first direction, at this time, since the first limiting portion 38 and the second limiting portion 40 are in contact with each other, the bottom cover 18 and the floating cover 20 still do not rotate, so that the bristle brush 21 can descend along the track 26.

[0136] When the brush 21 descends along the track 26, the floating cover 20 falls due to the loss of the upward force of the brush 21, so that the first limiting part 38 and the second limiting part 40 are separated from each other, at this time, the brush assembly 14 returns to the first position, the brush 21 contacts the ground, and the bottom cover 18 and the floating cover 20 can continue to rotate together with the brush 21.

[0137] Referring to FIG. 2, in some embodiments, the brush 21 comprises a support 42 and a cleaning brush 46, the cleaning brush 46 is installed on the support 42, the support 42 is arranged between the bottom cover 18 and the floating cover 20, and the thickness h1 of the support 42 is greater than the width h2 of the track 26 defined by the lifting part 22 and the recessed part 24.

[0138] In this way, the floating cover 20 can be lifted when the brush 21 rises along the track 26, so that the first limiting part 38 and the second limiting part 40 are in contact with each other.

[0139] Specifically, the brush 21 comprises a support 42 and a cleaning brush 46, the cleaning brush 46 is installed on the support 42. The support 42 is arranged between the bottom cover 18 and the floating cover 20, and the thickness h1 of the support 42 is greater than the distance h2 between the lifting part 22 and the recessed part 24, so that the floating cover 20 can be lifted when the brush 21 rises along the track 26.

[0140] Referring to FIG. 5, FIG. 6 and FIG. 11, in some embodiments, the bottom cover 18 comprises a clamping jaw 48, the floating cover 20 comprises a clamping groove 50, the clamping jaw 48 is clamped in the clamping groove 50 to limit the movement between the floating cover 20 and the bottom cover 18 along the rotation direction of the brush 21.

[0141] In this way, the clamping jaw 48 and the clamping groove 50 can limit the movement between the floating cover 20 and the bottom cover 18 along the rotation direction of the brush 21.

[0142] Specifically, the floating cover 20 is installed on the bottom cover 18, and the floating cover 20 can move along the direction of approaching or moving away from the ground, while the relative rotation between the floating cover 20 and the bottom cover 18 is required to be prevented. The bottom cover 18 comprises a clamping jaw 48, and the floating cover 20 comprises a clamping groove 50, the clamping jaw 48 is clamped in the clamping groove 50, and the side surface of the clamping groove 50 abuts against the side surface of the clamping jaw 48, so that the relative rotation between the bottom cover 18 and the floating cover 20 can be prevented.

[0144] In this way, part of the edge of the clamping jaw 48 is clamped on the resilient member 52, so that the floating cover 20 can move relative to the bottom cover 18 along the direction of approaching or moving away from the ground.

[0145] Specifically, the lifting assembly includes an elastic member 52, the floating cover 20 is provided with a receiving groove 51, and the elastic member 52 is received in the receiving groove 51. When the brush assembly 14 is in the first position, the elastic member 52 has a downward pressure on the floating cover 20, so that the brush 21 has a downward pressure when cleaning the ground, so that the brush 21 can more thoroughly contact and clean the ground. During switching of the brush assembly 14 from the second position to the first position, the brush 21 moves downward along the track 26 between the bottom cover 18 and the floating cover 20, the elastic member 52 has a downward pressure on the floating cover 20, and the first limiting portion 38 and the second limiting portion 40 can be separated from each other, at this time, the brush assembly 14 returns to the first position, the brush 21 contacts the ground, and the bottom cover 18 and the floating cover 20 can continue to rotate together with the brush 21.

[0146] In some embodiments, the driving assembly 12 includes a driving member 54 and a second transmission member, the driving member 54 is in transmission connection with the second transmission member, and the second transmission member is in transmission connection with the brush 21.

[0147] In this way, the driving assembly 12 can drive the brush 21 to rotate.

[0148] Specifically, the driving member 54 provides power, the second transmission member connects the driving member 54 and the brush 21, and is used for transmitting the power provided by the driving member 54 to the brush 21. The brush 21 is installed on the lifting assembly and can drive the lifting assembly to move together. In this way, the driving assembly 12 can drive the brush assembly 14 to move between the first position and the second position.

[0149] In one embodiment, as shown in FIGS. 3 and 4, the driving member 54 includes a motor, and the second transmission member includes a gear transmission member. The gear transmission member includes a first gear 58, a second gear 60, a third gear 62 and a fourth gear 64 which are sequentially engaged. The first gear is connected to an output shaft of the motor, and the fourth gear 64 is connected to the brush 21. In this way, the driving member 54 can drive the brush 21 to rotate. The second transmission member further includes a gear shaft 65 which is used for mounting and positioning the gears.

[0150] Alternatively, the driving member 54 includes any one of an electric driving member, a hydraulic driving member and a pneumatic driving member.

[0151] In some embodiments, the mounting seat 10 includes an upper shell 66 and a lower cover 68, the upper shell 66 is provided with a mounting groove 70, the driving member 54 is mounted in the mounting groove 70, and the upper shell 66 and the lower cover 68 form a receiving space 72 therebetween, and the second transmission member is received in the receiving space 72.

[0152] In this way, the second transmission member can be protected.

[0153] Specifically, the second transmission member connects the driving member 54 and the bristle brush 21, and is used to transmit the power provided by the driving member 54 to the bristle brush 21. The upper shell 66 and the lower cover 68 of the mounting base 10 form a containing space 72 therebetween, and the second transmission member is contained in the containing space 72. The mounting base 10 further comprises a closing cover 73, which is used to close the top of the containing space 72. The mounting base 10 provides a closed environment for the second transmission member, effectively preventing dust, sand, oil stains and other external factors from directly contacting the second transmission member, thereby reducing the wear and corrosion of the second transmission member, and prolonging the service life of the second transmission member.

[0154] In some embodiments, the bristle brush assembly 14 further comprises a lifting assembly, which comprises the bottom cover 18, the floating cover 20 and the second transmission member. The lower cover 68 is provided with a containing cavity 36, and the floating cover 20, the bristle brush 21 and the bottom cover 18 are sequentially arranged in the containing cavity 36. The bristle brush 21 is movably mounted between the floating cover 20 and the bottom cover 18. Referring to FIG. 12, the floating cover 20 is provided with a through hole 74. Referring to FIGS. 3, 4, 6 and 10, the driving assembly 12 comprises a third transmission member 76, the second transmission member is fixedly connected with the third transmission member 76, and the third transmission member 76 is fixedly connected with the bristle brush 21 by penetrating the through hole 74.

[0155] In this way, the bristle brush mechanism 100 has a compact structure, and the overall thickness of the bristle brush mechanism 100 can be reduced.

[0156] Specifically, the mounting base 10 comprises the upper shell 66 and the lower cover 68. The upper shell 66 is provided with a mounting groove 70 for mounting the driving member 54. The upper shell 66 and the lower cover 68 form a containing space 72 therebetween for containing the second transmission member. The lower cover 68 is provided with a containing cavity 36 for containing the floating cover 20, the bristle brush 21 and the bottom cover 18. The output shaft of the second transmission member extends out of the containing space 72, penetrates the floating cover 20 and is fixedly connected with the third transmission member 76. A copper sleeve 78 can be arranged between the floating cover 20 and the second transmission member, or a bearing can be arranged between the floating cover 20 and the second transmission member, thereby reducing the friction between the floating cover 20 and the second transmission member and playing a lubricating role.

[0157] The third transmission member 76 is fixedly connected with the bristle brush 21. The bottom cover 18 is mounted to the floating cover 20 from below the bristle brush 21. The first transmission member is located in the containing space 72 and extends out of the containing space 72. The bottom cover 18 is fixedly connected with the first transmission member by a fastener 80.

[0158] It can be understood that, in the same space, the outer layer of the bristle brush assembly 14 is a transmission system driven by the driving member 54, the second transmission member and the bristle brush 21, and the inner layer is a transmission system from the bristle brush 21, the bottom cover 18, the floating cover 20 to the first transmission member.

[0159] When the driving member 54 rotates in the first direction, the second transmission member is driven by the driving member 54 to drive the edge brush 21 to rotate in the first direction; when the driving member 54 rotates in the second direction, the driving member 54 drives the second transmission member to drive the edge brush 21 to rotate in the second direction, and the first transmission member is fixed and does not rotate, so that the bottom cover 18 and the floating cover 20 are fixed and do not rotate, and the edge brush 21 moves upward along the track 26 between the bottom cover 18 and the floating cover 20 in the second direction. In summary, the edge brush mechanism 100 has a compact structure, and the overall thickness of the edge brush mechanism 100 can be reduced.

[0160] In some embodiments, the inner wall surface of the through hole 74 and the outer peripheral surface of the third transmission member 76 are correspondingly provided with threads, so that the floating cover 20 can move relative to the bottom cover 18 in the direction of approaching or moving away from the ground.

[0161] In this way, the floating cover 20 can move relative to the bottom cover 18 in the direction of approaching or moving away from the ground.

[0162] Specifically, when the driving member 54 drives the edge brush 21 to rotate in the second direction, the floating cover 20 is lifted upward by the edge brush 21, and the threads between the inner wall surface of the through hole 74 and the outer peripheral surface of the third transmission member 76 are tightened. When the driving member 54 drives the edge brush 21 to rotate in the first direction, the floating cover 20 needs to overcome the force of the tightened threads and has a certain time of rotation stop, so that the edge brush 21 falls back to contact the ground.

[0163] It should be noted that when the driving member 54 drives the edge brush 21 to rotate in the second direction, the first transmission member is fixed and does not rotate, so that the edge brush 21 finally moves upward and is in a rotation stop state. Therefore, the working time of the driving member 54 can be set when the driving member 54 drives the edge brush 21 to rotate in the second direction, or the working current of the driving member 54 is detected, and the driving member 54 is stopped when the working current exceeds a preset value, so as to avoid damaging the driving member 54.

[0164] In summary, when the driving member 54 rotates in the first direction, the second transmission member is driven by the driving member 54 to drive the edge brush 21 to rotate in the first direction; when the driving member 54 rotates in the second direction, the driving member 54 drives the second transmission member to drive the edge brush 21 to rotate in the second direction, and the first transmission member is fixed and does not rotate, so that the bottom cover 18 and the floating cover 20 are fixed and do not rotate, and the edge brush 21 moves upward along the track 26 between the bottom cover 18 and the floating cover 20 in the second direction. Thus, the edge brush mechanism 100 can realize that the edge brush 21 contacts the ground for cleaning when rotating in the first direction, and the edge brush 21 moves upward and is separated from the ground when rotating in the second direction, so as to avoid liquid stains.

[0165] Referring to FIGS. 13-16, embodiments of the present application provide a cleaning device 3000, which further comprises a lifting assembly 300 and a bottom cover 18. The lifting assembly 300 is linked with the brush assembly 14 and the driving assembly 12. The bottom cover 18 is arranged at the end of the output shaft 30 of the driving assembly 12. The periphery of the bottom cover 18 is provided with a flange 410 facing the driving assembly 12, the flange 410 has a gap 411, the side wall of the gap 411 comprises an inclined surface 4111 inclined relative to the driving assembly 12, and the brush assembly 14 is slidingly fitted on the inclined surface 4111. The driving assembly 12 and the lifting assembly 300 are used to control the brush 21 to move towards or away from the driving assembly 12 along the inclined surface 4111 or rotate with the driving assembly 12.

[0166] In some embodiments, the brush 21 comprises a support and a cleaning brush, and the cleaning brush is arranged to be spaced apart from the driving assembly 12 by the support. In some embodiments, the support and the cleaning brush are detachably connected, so as to facilitate replacement of one or both of the support and the cleaning brush, and improve the utilization rate of parts. In some embodiments, the cleaning brush is made of a flexible material, such as rubber and / or silica gel, so as to improve the protection of the surface to be cleaned (such as the ground) when cleaning the surface to be cleaned.

[0167] In some embodiments, referring to FIG. 16, the first end 4111a and the second end 4111b of the inclined surface 4111 are spaced apart along the direction in which the brush assembly 14 rotates, and the distance between the first end 4111a and the driving assembly 12 is greater than the distance between the second end 4111b and the driving assembly 12. When the driving assembly 12 drives the brush assembly 14 to rotate in the second direction R2, the brush 21 rotates in the second direction R2 relative to the bottom cover 18 under the action of the lifting assembly 300, and the brush 21 moves along the first end 4111a of the inclined surface 4111 towards the second end 4111b of the inclined surface 4111, i.e., the brush 21 is displaced in the axial direction in which the brush assembly 14 rotates, i.e., the brush 21 is lifted relative to the surface to be cleaned and moves away from the surface to be cleaned, so as to reduce the possibility that the brush 21 touches the liquid on the surface to be cleaned, reduce the possibility that the liquid area increases or even splashes due to the rotation of the brush 21, and improve the adaptability of the brush mechanism 100 to different cleaning environments. When the driving assembly 12 drives the brush assembly 14 to rotate in the first direction R1, the brush 21 rotates in the first direction R1 relative to the bottom cover 18 under the action of the lifting assembly 300, and the brush 21 moves along the second end 4111b of the inclined surface 4111 towards the first end 4111a of the inclined surface 4111, i.e., the brush 21 is displaced in the axial direction in which the brush assembly 14 rotates, i.e., the brush 21 falls relative to the driving assembly 12 and approaches or even contacts the surface to be cleaned, so that the brush 21 can contact the surface to be cleaned, so as to facilitate the normal cleaning of the surface to be cleaned by the brush 21. When the driving assembly 12 drives the brush assembly 14 to rotate in the first direction R1, the brush 21 rotates with the driving assembly 12 to gather and clean the garbage objects on the surface to be cleaned. When the surface to be cleaned is wet or there is liquid on the cleaning path, the brush mechanism 100 of the present application is beneficial to improve the adaptability of the cleaning device 3000.

[0168] In some embodiments, referring to FIGS. 13-15, the driving assembly 12 includes a driving member 54, a second transmission member 220, and an output shaft 30. One end of the second transmission member 220 is in transmission connection with the driving member 54, and the other end is in transmission connection with the output shaft 30. The end of the output shaft 30 away from the second transmission member 220 is fixedly connected with the brush assembly 14.

[0169] The driving member 54 is configured to provide driving force to drive the operation of the brush assembly 14. The second transmission member 220 is configured to transmit the driving force generated by the driving member 54 to the output shaft 30. The output shaft 30 is configured to receive the rotary driving force from the driving member 54 and transmit it to the brush assembly 14.

[0170] The driving member 54 drives the output shaft 30 to rotate in the first direction R1 or the second direction R2 through the second transmission member 220. In some embodiments, the first direction R1 and the second direction R2 are opposite directions. When the driving member 54 drives the output shaft 30 to rotate in the second direction R2, the bristle assembly 14 is driven to rotate in the second direction R2 due to the fixed connection between the output shaft 30 and the bristle assembly 14. When the driving member 54 drives the output shaft 30 to rotate in the first direction R1, the bristle assembly 14 is driven to rotate in the first direction R1 due to the fixed connection between the output shaft 30 and the bristle assembly 14.

[0171] In some embodiments, please continue to refer to FIGS. 13-15, the bristle assembly 14 further comprises a fixing block 120. The bristle 21 is spaced apart from the output shaft 30 through the fixing block 120. One end of the fixing block 120 is fixedly connected with the output shaft 30, and the other end is fixedly connected with the bristle 21.

[0172] The fixing block 120 is used to fix the bristle 21, so that the bristle 21 can be assembled to the fixing block 120, and the assembly of the bristle 21 to the output shaft 30 is realized through the assembly of the fixing block 120 to the output shaft 30, which reduces the complexity of the assembly of parts, is conducive to the protection of the output shaft 30, and improves the service life of the driving assembly 12.

[0173] In some embodiments, please continue to refer to FIGS. 13-15, the lifting assembly 300 further comprises a mounting seat 10 and a one-way bearing 34. The output end of the mounting seat 10 is provided with an annular groove 311 and a sleeve 312. The sleeve wall of the sleeve 312 is the inner groove wall of the annular groove 311. The one-way bearing 34 is arranged in the annular groove 311 and is sleeved on the outer periphery of the sleeve 312. The one-way bearing 34 is used to rotate in the first direction R1 and is used to be locked in the second direction R2, and the first direction R1 and the second direction R2 are opposite directions.

[0174] The mounting seat 10 can reduce the input speed to a low output speed to control the rotation speed of the output shaft 30. The annular groove 311 of the mounting seat 10 is used to accommodate components such as the one-way bearing 34, which is conducive to the miniaturization of the bristle mechanism 100. The sleeve 312 provides necessary radial support and guidance for the output shaft 30, reduces the axial movement of the output shaft 30, thereby reducing wear and tear and improving efficiency, and improving the reliability and stability of the normal rotation of the output shaft 30. In some embodiments, the one-way bearing 34 is fixedly arranged in the annular groove 311. Since the one-way bearing 34 is sleeved on the outer periphery of the sleeve 312, the rotation of the one-way bearing 34 and the rotation of the output shaft 30 do not affect each other. The one-way bearing 34 is used to constrain the rotation and / or movement of other parts of the lifting assembly 300, so that the lifting assembly 300 and the bristle assembly 14 can operate respectively, so that they can move relatively, and then realize the lifting or falling of the bristle assembly 14 relative to the driving assembly 12.

[0175] In some embodiments, the second transmission member 220 is arranged in the mounting base 10. In some embodiments, the mounting base 10 comprises an upper shell 66 and a lower cover 68; a surface of the upper shell 66 is provided with a first through hole, so that the output shaft of the driving member 54 extends into the upper shell 66 and is in transmission connection with one end of the second transmission member 220; a surface of the lower cover 68 is provided with a second through hole, so that the output shaft 30 extends into the lower cover 68 and is in transmission connection with the other end of the second transmission member 220; a surface of the lower cover 68 away from the upper shell 66 is provided with an annular slot 311, and the portion of the lower cover 68 surrounded by the annular slot 311 is provided with the second through hole, so as to form a sleeve 312, so that the output shaft 30 extends out of the sleeve 312 and drives the rotation of the bristle assembly 14. In some embodiments, the upper shell 66 is provided with a copper ring, and the output shaft 30 is arranged in the copper ring.

[0176] In some embodiments, please continue to refer to FIGS. 13-15, the lifting assembly 300 comprises a rotation-stopping sliding block 330, which is slidingly sleeved on the outer periphery of the one-way bearing 34 and is in sliding connection with the one-way bearing 34; the bristle 21 is arranged between the rotation-stopping sliding block 330 and the bottom cover 18, and the minimum gap between the rotation-stopping sliding block 330 and the bottom cover 18 is smaller than the thickness of the bristle 21.

[0177] In some embodiments, the rotation-stopping sliding block 330 can rotate with the one-way bearing 34 or be rotation-stopped. Since the bristle 21 is arranged between the rotation-stopping sliding block 330 and the bottom cover 18, and the minimum gap between the rotation-stopping sliding block 330 and the bottom cover 18 is smaller than the thickness of the bristle 21, when the bristle 21 is located in the minimum gap between the rotation-stopping sliding block 330 and the bottom cover 18, the bristle 21 is warped and generates an acting force on the rotation-stopping sliding block 330. Since the rotation-stopping sliding block 330 is in sliding connection with the one-way bearing 34, the acting force on the rotation-stopping sliding block 330 pushes the rotation-stopping sliding block 330 to move in the axial direction of the rotation of the bristle assembly 14 and towards the driving assembly 12. For example, when the bristle 21 rotates in the second direction R2 relative to the bottom cover 18 under the action of the lifting assembly 300, the bristle 21 moves along the first end 4111a of the inclined surface 4111 towards the second end 4111b thereof, i.e., the bristle 21 is lifted relative to the surface to be cleaned, and the rotation-stopping sliding block 330 also moves in the axial direction of the rotation of the bristle assembly 14 and towards the driving assembly 12.

[0178] When the bristle 21 moves out of the minimum gap between the rotation-stopping slider 330 and the bottom cover 18, the force of the bristle 21 on the rotation-stopping slider 330 decreases, and the rotation-stopping slider 330 is displaced in the axial direction of the rotation of the bristle assembly 14 away from the driving assembly 12, that is, the rotation-stopping slider 330 falls relative to the driving assembly 12. For example, when the bristle 21 rotates relative to the bottom cover 18 in the first direction R1 under the action of the lifting assembly 300, the bristle 21 moves along the second end 4111b of the inclined surface 4111 toward the first end 4111a thereof, that is, the bristle 21 falls relative to the driving assembly 12, and the rotation-stopping slider 330 also moves along the axial direction of the rotation of the bristle assembly 14 away from the driving assembly 12.

[0179] In some embodiments, referring to FIGS. 15, 16 and 18, the rotation-stopping slider 330 is provided with a plurality of first protrusions 330a on one side thereof toward the annular slot 311, and the bottom of the annular slot 311 is provided with a plurality of second protrusions 311a. In response to the bristle 21 moving along the inclined surface 4111 toward the driving assembly 12, the rotation-stopping slider 330 moves toward the driving assembly 12, and the first protrusions 330a and the second protrusions 311a are staggered. In response to the bristle 21 moving along the inclined surface 4111 away from the driving assembly 12, the rotation-stopping slider 330 moves away from the driving assembly 12, and the first protrusions 330a and the second protrusions 311a are separated.

[0180] When the bristle 21 rotates relative to the bottom cover 18 in the second direction R2 under the action of the lifting assembly 300, the bristle 21 moves along the first end 4111a of the inclined surface 4111 toward the second end 4111b thereof, that is, the bristle 21 is lifted relative to the surface to be cleaned, and the rotation-stopping slider 330 also moves along the axial direction of the rotation of the bristle assembly 14 toward the driving assembly 12. The first protrusions 330a of the rotation-stopping slider 330 and the second protrusions 311a of the annular slot 311 are staggered, and the rotation-stopping slider 330 is “locked” to the mounting seat 10.

[0181] When the bristle 21 rotates relative to the bottom cover 18 in the first direction R1 under the action of the lifting assembly 300, the bristle 21 moves along the second end 4111b of the inclined surface 4111 toward the first end 4111a thereof, that is, the bristle 21 falls relative to the driving assembly 12, and the rotation-stopping slider 330 also moves along the axial direction of the rotation of the bristle assembly 14 away from the driving assembly 12. The first protrusions 330a of the rotation-stopping slider 330 and the second protrusions 311a of the annular slot 311 are separated, and the rotation-stopping slider 330 is “unlocked” to the mounting seat 10. The freedom of the one-way bearing 34 is released, and the bottom cover 18 is driven to rotate synchronously with the bristle assembly 14, thereby gathering and cleaning garbage objects on the surface to be cleaned through rotation.

[0182] In some embodiments, referring to FIG. 19, the first protrusion 330a and / or the second protrusion 311a has a slope S1 relative to the axial direction of the output shaft 30. In the case where the first protrusion 330a and the second protrusion 311a abut and press against each other, the slope S1 facilitates the relative movement of the first protrusion 330a and the second protrusion 311a from the state of abutting and pressing against each other to the state of dislocation, so as to reduce the damage to the components of the brush mechanism 100. In some embodiments, the slope S1 can be a straight slope or a curved slope.

[0183] In some embodiments, referring to FIGS. 13-15, the lifting assembly 300 includes a plug 340 and an elastic member 52. The plug 340 is sleeved on the outer periphery of the one-way bearing 34. The elastic member 52 is arranged between the plug 340 and the rotation-stopping slider 330.

[0184] The plug 340 is used to limit and constrain the elastic member 52, so as to facilitate the normal operation of the elastic member 52. The elastic member 52 is used to accumulate and release stress, so that the rotation-stopping slider 330 can maintain the state of pressing down the brush 21, thereby improving the cleaning ability of the brush assembly 14. In some embodiments, the elastic member 52 is a spring.

[0185] When the brush 21 rotates relative to the bottom cover 18 along the second direction R2 under the action of the lifting assembly 300, the brush 21 moves along the first end 4111a of the inclined surface 4111 towards the second end 4111b, i.e., the brush 21 is lifted relative to the surface to be cleaned, and the rotation-stopping slider 330 also moves along the axial direction of the rotation of the brush assembly 14 towards the driving assembly 12, and the elastic member 52 is compressed.

[0186] When the brush 21 rotates relative to the bottom cover 18 along the first direction R1 under the action of the lifting assembly 300, the brush 21 moves along the second end 4111b of the inclined surface 4111 towards the first end 4111a, i.e., the brush 21 falls relative to the driving assembly 12, and the rotation-stopping slider 330 also moves along the axial direction of the rotation of the brush assembly 14 away from the driving assembly 12, and the elastic member 52 releases stress and pushes the rotation-stopping slider 330 to move along the axial direction of the rotation of the brush assembly 14 away from the driving assembly 12, thereby maintaining the state of pressing down the brush 21.

[0187] In some embodiments, referring to FIGS. 13-15, the lifting assembly 300 includes a bottom cover fixing block 360. The bottom cover fixing block 360 is sleeved on the outer periphery of the one-way bearing 34 and is fixedly connected with the bottom cover 18. The brush 21 is arranged between the bottom cover fixing block 360 and the bottom cover 18.

[0188] The bottom cover fixing block 360 is used for fixing the bottom cover 18. The bottom cover fixing block 360 rotates with the rotation of the one-way bearing 34, and in turn drives the bottom cover 18 to rotate with the rotation of the one-way bearing 34.

[0189] In some embodiments, please continue to refer to FIGS. 13-17, the rotation-stopping sliding block 330 has a hollow inner ring 331, the inner ring 331 is provided with a plurality of grooves 3311, the bottom cover fixing block 360 is provided with a plurality of protrusions 361 close to one end of the bottom cover 18, the number of the protrusions 361 matches the number of the grooves 3311, and the protrusions 361 are assembled into the grooves 3311 of the rotation-stopping sliding block 330 in response to the bottom cover fixing block 360, the protrusions 361 and the inner walls of the grooves 3311 have a gap.

[0190] The protrusions 361 of the bottom cover fixing block 360 are inserted into the grooves 3311 of the rotation-stopping sliding block 330 to realize the assembly of the bottom cover fixing block 360 and the rotation-stopping sliding block 330. The protrusions 361 and the inner walls of the grooves 3311 have a gap, which provides a certain fault tolerance space for the bottom cover fixing block 360 and the rotation-stopping sliding block 330. In the case that the first protrusion 330a and the second protrusion 311a abut and extrude each other, due to the existence of the gap, the one-way bearing 34 and the bottom cover fixing block 360 can move a certain degree relative to the rotation-stopping sliding block 330, that is, the rotation-stopping sliding block 330 moves a certain degree relative to the mounting seat 10, so that the first protrusion 330a and the second protrusion 311a move relative to each other, and the state of abutting and extruding each other changes to the state of dislocation, so as to reduce the damage to the parts of the brush mechanism 100.

[0191] The movement process of the lifting, falling and normal operation of the brush assembly 14 is described in detail below.

[0192] When the cleaning device 3000 cleans the surface to be cleaned, the driving assembly 12 drives the brush assembly 14 to rotate in the first direction R1, the brush 21 rotates with the driving assembly 12 in the first direction R1, and drives the bottom cover 18 to rotate synchronously with the brush 21, the brush assembly 14 and the lifting assembly 300 rotate synchronously, and the garbage objects on the surface to be cleaned are gathered and swept through rotation.

[0193] When the cleaning device 3000 detects liquid in front of the cleaning device 3000, and the brush 21 needs to be lifted, the driving assembly 12 drives the brush assembly 14 to rotate in the second direction R2. Since the one-way bearing 34 is locked in the second direction R2, the bottom cover 18 is also locked in the second direction R2, and the brush 21 rotates relative to the bottom cover 18. Since the bottom cover 18 includes the inclined surface 4111, the brush 21 moves along the inclined surface 4111 towards the driving assembly 12, that is, the brush 21 is lifted relative to the surface to be cleaned. Since the minimum gap between the locking block 330 and the bottom cover 18 is smaller than the thickness of the brush 21, when the brush 21 is located in the minimum gap between the locking block 330 and the bottom cover 18, the brush 21 is bent, and an acting force is generated on the locking block 330. Since the locking block 330 is in sliding connection with the one-way bearing 34, the acting force generated on the locking block 330 drives the locking block 330 to move in the axial direction of the brush assembly 14 towards the driving assembly 12, and the first protrusion 330a of the locking block 330 is in interlocking with the second protrusion 311a of the annular slot 311 of the mounting seat 10, so that the locking block 330 is “locked” to the mounting seat 10, that is, the lifting assembly 300 is “locked” to the mounting seat 10.

[0194] When the cleaning device 3000 needs the brush 21 to fall to re-contact the surface to be cleaned, the driving assembly 12 drives the brush assembly 14 to rotate in the first direction R1. Since the one-way bearing 34 rotates in the first direction R1, the bottom cover 18 should also rotate in the first direction R1, but since the one-way bearing 34 is “locked” to the mounting seat 10 when the brush 21 is lifted, the one-way bearing 34 cannot rotate, and thus the bottom cover 18 also cannot rotate. Therefore, in the stage when the one-way bearing 34 is “locked” to the mounting seat 10, the brush 21 can rotate in the first direction R1, and the bottom cover 18 is locked in the first direction R1, and the brush 21 rotates relative to the bottom cover 18 in the first direction R1, so that the brush 21 moves along the second end 4111b of the inclined surface 4111 towards the first end 4111a thereof, that is, the brush 21 moves in the axial direction of the brush assembly 14, that is, the brush 21 falls relative to the driving assembly 12.

[0195] Since the brush 21 falls relative to the driving assembly 12, the locking block 330 also moves in the axial direction of the brush assembly 14 away from the driving assembly 12, and the elastic member 52 releases the stress to drive the locking block 330 to move in the axial direction of the brush assembly 14 away from the driving assembly 12, so as to keep the brush 21 in the state of being pressed, and thus the first protrusion 330a of the locking block 330 is separated from the second protrusion 311a of the annular slot 311, and the locking block 330 is “unlocked” to the mounting seat 10, and the freedom of the one-way bearing 34 is released, so that the bottom cover 18 rotates synchronously with the brush assembly 14, and the garbage objects on the surface to be cleaned are gathered and cleaned through rotation.

[0196] In summary, by setting the side brush assembly 14, the driving assembly 12, the lifting assembly 300 and the bottom cover 18 on the side brush mechanism 100, the bottom cover 18 comprises an inclined surface 4111, the side brush assembly 14 is slidingly fitted on the inclined surface 4111, the inclined surface 4111 has a first end 4111a facing the bottom cover 18 and a second end 4111b facing the driving assembly 12, the driving assembly 12 and the lifting assembly 300 are used to control the side brush 21 to move along the inclined surface 4111 towards or away from the driving assembly 12, so that the side brush 21 is lifted or dropped relative to the surface to be cleaned, or rotates with the driving assembly 12, so that the side brush assembly 14 normally operates. When the ground is wet or there is liquid on the cleaning path, the arrangement of the side brush mechanism 100 of the present application is beneficial to improve the use adaptability of the cleaning equipment 3000.

[0197] Referring to FIGS. 20-26, the embodiment of the present application provides a cleaning equipment 3000. The cleaning equipment 3000 further comprises a combing member 2100.

[0198] The combing member 2100 is arranged on the equipment body 2000, and the combing member 2100 can be installed on the side of the equipment body 2000 facing the surface to be cleaned by insertion, assembly, combination or the like. The combing member 2100 can be connected with the equipment body 2000 by welding, bonding or threaded connection, and of course the combing member 2100 can also be integrally formed with the shell on the side of the equipment body 2000 facing the surface to be cleaned.

[0199] The side brush mechanism 100 further comprises a state switching assembly 430, which is used to enable the side brush 21 to switch between a first state and a second state. As shown in FIG. 20, the side brush 21 contacts the surface to be cleaned in the first state, and the side brush 21 collects garbage on the surface to be cleaned by rotating. The side brush 21 does not contact the combing member 2100 in the first state, so that the combing member 2100 does not affect the normal cleaning work of the side brush 21 on the surface to be cleaned, and as shown in FIG. 21, the side brush 21 contacts the combing member 2100 away from the surface to be cleaned in the second state, so that the combing member 2100 uses the rotation of the side brush 21 to clean the hair wound on the side brush 21.

[0200] By setting the grooming member 2100, the bristle 21 contacts the surface to be cleaned in the first state to clean the surface to be cleaned by rotating, and contacts the grooming member 2100 in the second state, so that the grooming member 2100 can clean the hair entangled on the bristle 21. By setting the bristle 21 to have the first state and the second state that can be switched with each other, the cleaning process of the bristle 21 on the surface to be cleaned and the cleaning process of the grooming member 2100 on the bristle 21 are distinguished, the bristle 21 on the bristle 21 is effectively cleaned without hindering the normal cleaning work of the bristle 21, the self-cleaning function of the bristle 21 of the cleaning device 3000 is effectively realized, the reliability and effectiveness of the cleaning work of the bristle 21 are effectively improved, and the applicability of the cleaning device 3000 is effectively improved.

[0201] In some embodiments, as shown in FIGS. 22 and 23, the bristle mechanism 100 includes a bottom cover 18 and at least one bracket 42, the bracket 42 has a first end 301 and a second end 302 arranged opposite to each other, and the first end 301 of the bracket 42 is rotationally connected with the bottom cover 18. The driving assembly 12 is in transmission connection with the bottom cover 18, and the driving assembly 12 can drive the bottom cover 18 to rotate relative to the device body 2000 with the first rotation axis L1 as the center. The number of the bracket 42 can be one, two, three, and of course can also be other numbers.

[0202] In some embodiments, as shown in FIG. 23 and FIG. 24, the angle A between the line connecting the first end 301 and the second end 302 of the bracket 42 and the first rotation axis L1 in the first state is different from the angle A between the line connecting the first end 301 and the second end 302 of the bracket 42 and the first rotation axis L1 in the second state, and the second end 302 of the bracket 42 is closer to the device body 2000 in the second state than in the first state. Alternatively, the angle A between the line connecting the first end 301 and the second end 302 of the bracket 42 and the first rotation axis L1 in the direction towards the surface to be cleaned in the first state is smaller than the angle A between the line connecting the first end 301 and the second end 302 of the bracket 42 and the first rotation axis L1 in the direction towards the surface to be cleaned in the second state, that is, in the first state, the bracket 42 is lowered, and the second end 302 of the bracket 42 points to the surface to be cleaned to contact the surface to be cleaned, while in the second state, the bracket 42 is raised, and the second end 302 of the bracket 42 points to the device body 2000 to be away from the surface to be cleaned, and contacts the grooming member 2100 to facilitate the grooming member 2100 to clean the hair wound on the bracket 42. By setting the angle A between the line connecting the first end 301 and the second end 302 of the bracket 42 and the first rotation axis L1 in the first state and the second state to be different, the pose of the bracket 42 relative to the surface to be cleaned and the grooming member 2100 in the first state and the second state is different, thereby distinguishing the first state in which the bracket 42 cleans the surface to be cleaned and the second state in which the grooming member 2100 cleans the hair on the bracket 42, effectively reducing the possibility of mutual influence and interference between the two, effectively improving the reliability and stability of the cleaning device 3000 in cleaning the surface to be cleaned, while improving the reliability and stability of the grooming member 2100 in cleaning the bracket 42, effectively realizing the self-cleaning function of the cleaning device 3000, and improving the applicability of the cleaning device 3000.

[0203] In some embodiments, as shown in FIGS. 22-24, the bracket 42 is arranged to rotate relative to the bottom cover 18 about a preset second rotation axis L2 under the action of the state switching assembly 430, and the first rotation axis L1 and the second rotation axis L2 are arranged to intersect, i.e., on the basis of the bottom cover 18 driving the bracket 42 to rotate about the first rotation axis L1, the bracket 42 can rotate relative to the bottom cover 18 about the second rotation axis L2. Further, in the first state, the bracket 42 rotates relative to the bottom cover 18 to realize lowering, and the second end 302 of the bracket 42 points to the surface to be cleaned to contact the surface to be cleaned, while in the second state, the bracket 42 rotates relative to the bottom cover 18 to realize lifting, and the second end 302 of the bracket 42 points to the device main body 2000 to be away from the surface to be cleaned and contact the grooming member 2100 to facilitate the grooming member 2100 to clean the hair wound on the bracket 42. By rotating the bracket 42 relative to the bottom cover 18 to realize that the bracket 42 respectively contacts the surface to be cleaned in the first state and contacts the grooming member 2100 in the second state, the structure is simple, the switching is quick and convenient, and the efficiency of switching the relative position of the bracket 42 between the first state and the second state is effectively improved, and then the efficiency of switching the edge brush 21 between the first state and the second state is effectively improved.

[0204] In some embodiments, as shown in FIGS. 23 and 24, the edge brush 21 further includes a cleaning brush 46 arranged at the second end 302 of the bracket 42. The cleaning brush 46 rotates synchronously with the bracket 42, i.e., the cleaning brush 46 can rotate about the first rotation axis L1 with the bracket 42 when the bottom cover 18 drives the bracket 42 to rotate about the first rotation axis L1, and can rotate relative to the bottom cover 18 about the second rotation axis L2 with the bracket 42 to realize lifting and lowering of the cleaning brush 46, and then realize that the cleaning brush 46 respectively contacts the surface to be cleaned and the grooming member 2100 in the first state and the second state.

[0205] In some embodiments, as shown in FIGS. 20 and 23, the driving assembly 12 drives the bottom cover 18 to rotate around the first rotation axis L1 in the first direction R1 in the first state, thereby driving the bracket 42 and the cleaning brush 46 to rotate around the first rotation axis L1 in the first direction R1, and the cleaning brush 46 contacts the surface to be cleaned and collects and sweeps the garbage objects on the surface to be cleaned. As shown in FIGS. 21 and 24, the driving assembly 12 drives the bottom cover 18 to rotate around the first rotation axis L1 in the second direction R2 in the second state, thereby driving the bracket 42 and the cleaning brush 46 to rotate around the first rotation axis L1 in the second direction R2, and the cleaning brush 46 cyclically contacts the grooming member 2100. By arranging the cleaning brush 46 to rotate around the first rotation axis L1 in the first direction R1 when contacting the surface to be cleaned in the first state, and to rotate around the first rotation axis L1 in the second direction R2 when contacting the grooming member 2100 in the second state, the second direction R2 and the first direction R1 are opposite directions, so that the hair on the surface to be cleaned is rotated and wound on the cleaning brush 46 rotating in the first direction R1, and the hair on the cleaning brush 46 rotating in the second direction R2 opposite to the first direction R1 is combed off by the grooming member 2100, effectively improving the efficiency of cleaning the hair on the cleaning brush 46, effectively reducing the possibility of further winding the hair on the cleaning brush 46 due to the contact between the grooming member 2100 and the cleaning brush 46, and effectively improving the effectiveness and reliability of the grooming work of the grooming member 2100.

[0206] In some embodiments, as shown in FIG. 25, the grooming member 2100 is provided with a plurality of comb teeth 2101 arranged at intervals from each other, and the driving assembly 12 drives the bottom cover 18 to rotate around the first rotation axis L1 in the second direction R2 in the second state, thereby driving the bracket 42 and the cleaning brush 46 to rotate around the first rotation axis L1 in the second direction R2 and contact the grooming member 2100, so as to realize that the driving assembly 12 drives the cleaning brush 46 to cyclically pass through the comb tooth gaps 2102 between the plurality of comb teeth 2101 in the second state. By the plurality of comb teeth 2101 cleaning the hair on the cleaning brush 46, the efficiency of cleaning the hair on the cleaning brush 46 is effectively improved, and the effectiveness and reliability of the grooming work of the grooming member 2100 are effectively improved.

By arranging the bristle brush 21 to have the first state and the second state which can be switched with each other, the cleaning process of the bristle brush 21 on the surface to be cleaned and the cleaning process of the carding member 2100 on the bristle brush 21 are separated, the hair wound on the bristle brush 21 is effectively cleaned without hindering the normal cleaning work of the bristle brush 21, the self-cleaning function of the bristle brush 21 of the cleaning device 3000 is effectively realized, the reliability and effectiveness of the cleaning work of the bristle brush 21 are effectively improved, and the applicability of the cleaning device 3000 is effectively improved.

[0219] In some embodiments, referring to FIG. 27 and FIG. 28, the embodiments of the present application provide a cleaning device 3000, and the bristle brush mechanism 100 of the cleaning device 3000 further comprises a base 14a and a blocking structure 200. At least one blocking structure 200 is arranged on the base 14a and arranged along the circumference of the rotating center of the bristle brush assembly 14, wherein the blocking structure 200 is configured to block the flexible object to avoid the flexible object from winding on the second transmission member of the transmission connection of the bristle brush assembly 21.

[0220] The base 14a is used to assemble other accessories of the bristle brush assembly 14, and the base 14a has a bottom 111 and a top 121, the bottom 111 faces the surface to be cleaned, and the top 121 faces the shell of the cleaning device 3000 connected with the bristle brush mechanism 100.

[0221] The base 14a is provided with a mounting bracket 140, and the mounting bracket 140 is provided with a plurality of brackets 42, which are arranged at intervals around the circumference of the mounting bracket 140 and extend out of the base 14a. Each bracket 42 is provided with a cleaning brush 46 made of nylon.

[0222] The base 14a is provided with a blocking structure 200 arranged along the circumference of the rotation center of the brush assembly 14. When the brush assembly 14 rotates, the blocking structure 200 can block flexible objects such as hair to avoid the flexible objects from winding around the second transmission member 220 connected in transmission with the brush assembly 14.

[0223] When the brush assembly 14 rotates, the cleaning brushes 46 of the brush assembly 14 rotate and clean the ground. When the cleaning brushes 46 clean flexible objects such as hair, part of the flexible objects such as hair will move in the direction of the cleaning brushes 46 and move upward along the cleaning brushes 46 with the rotation of the brush assembly 14. When the flexible objects such as hair move upward to the blocking structure 200, they are intercepted by the blocking structure 200 and cannot move upward any more. Therefore, the flexible objects such as hair cannot enter the area of the transmission shaft 530 of the brush mechanism 100, cannot wind around the transmission shaft 530 of the brush mechanism 100, and cannot enter the speed reduction mechanism (the second transmission member 220) of the brush mechanism 100, thereby avoiding overloading or jamming of the speed reduction mechanism and ensuring normal cleaning operation of the cleaning device and avoiding rotation failure of the brush assembly 14, thereby prolonging the service life of the brush assembly 14.

[0224] Referring to FIGS. 27 and 28, in some embodiments, the blocking structure 200 is arranged on the end surface of the base 14a opposite to the housing of the cleaning device 3000 and extends along the axial direction of the brush assembly 14. In other words, the blocking structure 200 is arranged on the top 121 of the base 14a, and one end of the blocking structure 200 is close to the housing of the cleaning device 3000. Therefore, the blocking structure 200 is arranged on the path of the flexible objects such as hair entering the area of the transmission shaft 530 and intercepts the flexible objects such as hair before they enter the area of the transmission shaft 530, thereby blocking the path of the flexible objects such as hair from the cleaning brushes 46 to the area of the transmission shaft 530. Therefore, the flexible objects such as hair cannot enter the area of the transmission shaft 530 of the brush assembly 14, cannot wind around the transmission shaft 530 of the brush assembly 14, and cannot enter the speed reduction mechanism of the brush assembly 14, thereby avoiding overloading or jamming of the speed reduction mechanism and ensuring normal cleaning operation of the cleaning device and avoiding rotation failure of the brush assembly 14, thereby prolonging the service life of the brush assembly 14.

[0225] It can be understood that the blocking structure 200 can also be arranged at the edge of the base 14a close to the top 121, which is not limited here.

[0226] It should be noted that the second transmission member 220 in transmission connection with the edge brush assembly 14 includes a transmission shaft 530 and a speed reduction mechanism.

[0227] Referring to FIGS. 27, 28 and 29, in some embodiments, the blocking structure 200 includes a connecting portion 210 and a hook portion 210a, one end of the connecting portion 210 is connected with the base 14a and extends away from the base 14a, and the hook portion 210a is arranged at the end of the connecting portion 210 away from the base 14a and extends away from the rotation center of the edge brush assembly 14. When the edge brush assembly 14 rotates, the cleaning brush 46 of the edge brush assembly 14 rotates and sweeps the ground, when the cleaning brush 46 sweeps to the flexible objects such as hair, part of the flexible objects such as hair will move and wind in the direction of the cleaning brush 46, and move upward along the cleaning brush 46 with the rotation of the edge brush assembly 14, when the flexible objects such as hair move upward to the blocking structure 200, they are intercepted by the hook portion 210a and wind around the connecting portion 210 and the hook portion 210a, and the flexible objects such as hair stop at the blocking structure 200 and no longer move upward, so the flexible objects such as hair cannot enter the area of the transmission shaft 530 and cannot wind around the transmission shaft 530 of the edge brush assembly 14, nor enter the speed reduction mechanism (the second transmission member 220) of the edge brush assembly 14, thereby avoiding causing the speed reduction mechanism to overload or jam, ensuring the normal sweeping operation of the cleaning device, avoiding causing the rotation failure of the edge brush assembly 14, and improving the service life of the edge brush assembly 14.

[0228] It should be noted that the blocking structure 200 can also adopt other structure types, for example, in one embodiment, a plurality of grooves are arranged on the side of the blocking structure 200 away from the rotation center of the edge brush assembly 14, the grooves are arranged in a direction perpendicular to the axis of the edge brush assembly 14, and the plurality of grooves are arranged in the axial direction of the edge brush assembly 14, and the plurality of grooves correspond to a plurality of hook portions 210a, when the flexible objects such as hair move upward along the blocking structure 200, the plurality of grooves play a role of step-by-step interception for the flexible objects such as hair, thereby effectively intercepting the flexible objects such as hair. In another embodiment, an adhesive layer is arranged on the side of the blocking structure 200 away from the rotation center of the edge brush assembly 14, the flexible objects such as hair moving to the blocking structure 200 are bonded by the adhesive layer, and the purpose of intercepting the flexible objects such as hair is also achieved. In this embodiment, the adhesive layer can be a glue layer, a magic tape or the like.

[0229] Referring to FIGS. 27, 28, 29, in some embodiments, the blocking structure 200 comprises a connecting portion 210 and a hook portion 210a, the connecting portion 210 is provided with reinforcing ribs 230 on both sides, the reinforcing ribs 230 are connected with the connecting portion 210 and extend along the circumference of the base 14a, by providing the reinforcing ribs 230 on both sides of the connecting portion 210, the strength of the blocking structure 200 can be increased, and the interception area of the blocking structure 200 can be increased, the probability of intercepting flexible objects such as hair is improved, and the probability of flexible objects such as hair entering the area of the transmission shaft 530 is reduced.

[0230] Referring to FIGS. 27, 28, in some embodiments, the mounting bracket 140 is provided with three brackets 42, the three brackets 42 are uniformly and spacedly arranged around the circumference of the mounting bracket 140, each bracket 42 is provided with a cleaning brush 46, and the blocking structure 200 is provided with three, the three blocking structures 200 are arranged one by one corresponding to the three brackets 42 and are spacedly arranged along the circumference of the base 14a. That is, referring to FIG. 27, the blocking structure 200 is arranged on the base 14a and close to the connecting portion of the corresponding bracket 42 and the base 14a. Thus, when the edge brush assembly 14 rotates, the cleaning brush 46 of the edge brush assembly 14 rotates and sweeps the ground, when the cleaning brush 46 sweeps the flexible objects such as hair, the flexible objects such as hair move upward along the cleaning brush 46 to the connecting portion of the bracket 42 and the base 14a, when the upward movement path of the flexible objects such as hair is about to widen, the flexible objects such as hair are intercepted by the blocking structure 200, so that the interception efficiency is further improved.

[0231] It should be noted that the number of brackets 42 can be two or more according to specific needs, and the number of blocking structures 200 can be arranged according to the number of brackets 42 or according to actual needs, which is not limited here.

[0232] Referring to FIG. 28, in some embodiments, the base 14a comprises a bottom cover 18 and an upper cover 19, the upper cover 19 and the bottom cover 18 are fixedly connected by ultrasonic welding or fastener connection, an installation cavity 130 is formed between the bottom cover 18 and the upper cover 19, the mounting bracket 140 is arranged in the installation cavity 130, the bottom cover 18 is provided with a plurality of avoiding notches 112, the avoiding notches 112 are communicated with the installation cavity 130, and the avoiding notches 112 are provided for the bracket 42. Thus, the assembly and positioning of the mounting bracket 140 on the base 14a can be facilitated, and the assembly difficulty of the mounting bracket 140 is reduced.

[0233] In some embodiments, the blocking structure 200 can be arranged on the bottom cover 18, or arranged on the upper cover 19, and the blocking structure 200 and the base 14a can be a split structure. Specifically, the bottom cover 18, the upper cover 19 and the blocking structure 200 are all separate components, and the bottom cover 18, the upper cover 19 and the blocking structure 200 are detachably connected through a connecting structure or a fastener, or fixedly connected through ultrasonic welding.

[0234] It should be noted that the blocking structure 200 and the base 14a can also be an injection-molded integrated structure. In addition, the bottom cover 18 and the upper cover 19 can also be an integrated structure, so as to reduce the components of the brush assembly 14 and reduce the assembly process. The bottom cover 18 and the upper cover 19 can be an integrated structure, which can be fixedly connected through ultrasonic welding, or integrally formed through injection molding.

[0235] Referring to FIG. 28, in some embodiments, the bottom cover 18 is provided with three insertion pieces 113, which extend along the axial direction of the brush assembly 14 and are uniformly spaced along the circumferential direction of the rotation center of the brush assembly 14. The upper cover 19 is correspondingly provided with three avoiding holes 122, which are uniformly spaced along the circumferential direction of the rotation center of the brush assembly 14. The insertion piece 113 is inserted into the corresponding avoiding hole 122. When assembling the bottom cover 18 and the upper cover 19, the insertion piece 113 is inserted into the corresponding avoiding hole 122, which is convenient and fast. By providing three insertion pieces 113 and three corresponding avoiding holes 122, blind insertion of the bottom cover 18 and the upper cover 19 during assembly can be achieved.

[0236] Referring to FIG. 28, the insertion piece 113 is provided with a hook 114, and the transmission shaft 530 of the drive assembly 12 of the brush mechanism 100 is provided with a corresponding buckle groove 640. When the brush assembly 14 is connected with the drive assembly 12, the hook 114 is clamped in the buckle groove 640. Through the cooperation of the hook 114 and the buckle groove 640, the drive assembly 12 drives the brush assembly 14 to rotate. In addition, through the cooperation of the hook 114 and the buckle groove 640, the brush assembly 14 is convenient to disassemble and install.

[0237] It should be noted that the number of insertion pieces 113 and avoiding holes 122 can also be two or more, which will not be described here.

[0238] Referring to FIG. 27, in some embodiments, the bracket 42 is configured as a rubber strip, and the mounting bracket 140 is capable of moving along the axial direction of the brush assembly 14, and the bracket 42 abuts against the bottom edge of the avoiding gap 112. When the brush assembly 14 is assembled to the cleaning device, the bottom edge of the avoiding gap 112 abuts against the lower part of the bracket 42, the bracket 42 is in a deformed state, and the end of the cleaning brush 46 is upwardly tilted and does not contact the ground. When the cleaning device 3000 is used, the driving assembly 12 of the brush mechanism 100 drives the mounting bracket 140 to move upwardly along the axial direction of the brush assembly 14, and the deformation of the bracket 42 is restored, so that the end of the cleaning brush 46 moves downwardly to contact the ground, thereby achieving the sweeping function when the brush assembly 14 rotates.

[0239] Referring to FIG. 27 and FIG. 28, in some embodiments, the mounting bracket 140 is provided with a connecting piece 143, the connecting piece 143 is provided with a threaded hole 144, and the output shaft 30 of the brush mechanism 100 is used to be threadedly connected with the threaded hole 144. Since the output shaft 30 is threadedly connected with the threaded hole 144 on the connecting piece 143, the mounting bracket 140 can be raised or lowered by the forward rotation and reverse rotation of the driving assembly 12, thereby lowering or raising the cleaning brush 46.

[0240] Specifically, when the cleaning device starts the sweeping operation, the driving assembly 12 drives the mounting bracket 140 to move upwardly along the axial direction of the brush assembly 14 through the output shaft 30, the bracket 42 is restored, and the end of the cleaning brush 46 moves downwardly to contact the ground under the elastic action of the bracket 42, thereby achieving the sweeping function; after the sweeping is completed, the driving assembly 12 drives the mounting bracket 140 to move downwardly along the axial direction of the brush assembly 14 through the output shaft 30, the bottom edge of the avoiding gap 112 abuts against the lower part of the bracket 42, and the bracket 42 is in a deformed state, so that the end of the cleaning brush 46 is upwardly tilted and the cleaning brush 46 is separated from the ground.

[0241] It can be understood that the connecting piece 143 can be a nut, the nut can be made of the same material as the mounting bracket 140, and the nut can be fixedly connected with the mounting bracket 140 by welding or one-piece forming.

[0242] Referring to FIG. 27 and FIG. 28, in some embodiments, a convex rib 145 is arranged on the side of the bracket 42 away from the axis of the brush assembly 14, the convex rib 145 is used to cooperate with the elastic piece of the device main body 2000, so that the current of the driving piece 54 of the cleaning device 3000 changes, thereby positioning the position of the cleaning brush 46 by detecting the change of the current of the driving piece 54, so that when the brush assembly 14 stops rotating, the cleaning brush 46 can avoid the position of the downward-looking sensor of the cleaning device 3000, and the cleaning brush 46 does not directly stop facing forward.

[0243] Referring to FIG. 30, the cleaning device 3000 according to an embodiment of the present application includes a driving member 54, a speed reduction mechanism connected with the driving member 54, and the edge brush assembly 14 according to any one of the above embodiments, the edge brush assembly 14 being in transmission connection with the speed reduction mechanism through a transmission shaft 530. When the edge brush assembly 14 rotates, the flexible objects such as hairs wound on the cleaning brush 46 of the edge brush assembly 14 move upward along with the rotation of the edge brush assembly 14, and when the flexible objects move to the blocking structure 200, the flexible objects are intercepted by the blocking structure 200 and no longer move upward, so as not to be wound on the transmission shaft 530 of the edge brush assembly 14, nor to enter the speed reduction mechanism of the edge brush assembly 14, thereby avoiding overloading or jamming of the speed reduction mechanism, ensuring normal cleaning operation of the cleaning device 3000, avoiding rotation failure of the edge brush assembly 14, and prolonging the service life of the edge brush assembly 14.

[0244] In some embodiments, the edge brush assembly 14 is detachably connected with the transmission shaft 530. When the edge brush assembly 14 is detached, the flexible objects such as hairs are hung on the blocking structure 200, and the flexible objects can be detached together with the edge brush assembly 14. Thus, after the cleaning operation is completed, the user only needs to pull out the edge brush assembly 14, and the flexible objects such as hairs are hung on the blocking structure 200 and detached together, so as to clean out the flexible objects such as hairs, thereby reducing the cleaning frequency and cleaning time of the user, improving the user experience, and improving the product competitiveness.

[0245] Referring to FIGS. 31 to 34, the functions of the cleaning device according to the present application are specifically described below by taking the cleaning operation of a cleaning device according to a specific embodiment as an example.

[0246] In the present embodiment, the driving member 54 of the driving assembly 12 of the edge brush mechanism 100 is connected with the edge brush assembly 14 through the speed reduction mechanism to drive the edge brush assembly 14 to rotate. Specifically, the output shaft 30 of the edge brush assembly 14 is rotatably arranged in the housing of the speed reduction mechanism through the one-way bearing 34, one end of the output shaft 30 is fixedly connected with a damping ring 370, the damping ring 370 and a damping cover 380 arranged on the housing of the speed reduction mechanism can be engaged or separated, the other end of the output shaft 30 is provided with a thread, the edge brush assembly 14 is provided with a connecting piece 143, the connecting piece 143 is provided with a threaded hole 144, and the output shaft 30 can be threadedly connected with the threaded hole 144.

[0247] When the cleaning device 3000 starts the cleaning operation, the driving member 54 rotates forward, the brush assembly 14 rotates through the speed reduction mechanism, and the damping cover 380 and the damping ring 370 are engaged, so that the output shaft 30 cannot rotate with the brush assembly 14. At this time, the connecting end of the output shaft 30 is screwed into the threaded hole 144 of the connecting member 143, the connecting member 143 rises, drives the mounting bracket 140 to move upward along the axial direction of the brush assembly 14, the bracket 42 returns to its original position, and under the elastic force of the bracket 42, the end of the cleaning brush 46 moves downward to contact the ground, and the damping cover 380 and the damping ring 370 are disengaged and no longer engaged.

[0248] The driving member 54 continues to rotate forward, the brush assembly 14 continues to rotate, and the cleaning brush 46 of the brush assembly 14 rotates and cleans the ground. When the cleaning brush 46 cleans the flexible material such as hair, part of the flexible material such as hair moves in the direction of the cleaning brush 46 and moves upward along the cleaning brush 46 with the rotation of the brush assembly 14. When the flexible material such as hair moves upward to the blocking structure 200, it is intercepted by the hook portion 210a and wound around the connecting portion 210 and the hook portion 210a. The flexible material such as hair stays at the blocking structure 200 and no longer moves upward. Therefore, the flexible material such as hair cannot enter the area of the transmission shaft 530 and cannot wind around the transmission shaft 530 of the brush assembly 14, nor enter the speed reduction mechanism of the brush assembly 14, thereby avoiding causing the speed reduction mechanism to be overloaded or stuck, to ensure the normal cleaning operation of the cleaning device.

[0249] After the cleaning is completed, the driving member 54 reverses. Since the output shaft 30 is arranged in the housing of the speed reduction mechanism through the one-way bearing 34, when the driving member 54 reverses, the one-way bearing 34 clamps the output shaft 30, and the output shaft 30 does not rotate. The brush assembly 14 rotates, the output shaft 30 gradually exits from the threaded hole 144 of the connecting member 143, drives the connecting member 143 to descend, thereby driving the mounting bracket 140 to move downward along the axial direction of the brush assembly 14. The bottom edge of the avoiding gap 112 abuts against the lower part of the bracket 42, the bracket 42 is in a deformed state, the end of the cleaning brush 46 is raised upward, the cleaning brush 46 is separated from the ground, and the cleaning brush 46 is collected.

[0250] When it is necessary to clean the flexible material such as hair on the brush assembly 14, the brush assembly 14 can be pulled off the driving assembly 12. Therefore, the user's cleaning frequency and cleaning time can be reduced, the user experience can be improved, and the product competitiveness can be improved.
