[0031] Please refer to Figure 1 And Figure 2 The cleaning equipment 100 of the utility model embodiment includes the chassis 102, the roller assembly 20, the cleaning piece 40.The roller assembly 20 includes support 21 and roller 22, support 21 rotatably mounted on the chassis 102, roller 22 rotatably mounted on support 21;Cleaning piece 40 is connected with the chassis 102, and the cleaning piece 40 is used to contact the outer surface 220 of the roller 22.

[0032] In the cleaning device 100 of the embodiment of the utility model, the cleaning member 40 can effectively remove the winding objects such as hair, fiber and pet hair adhered to the outer surface 220 of the roller 22 in the process of contacting with the outer surface 220 of the roller 22. This can reduce the possibility of winding objects accumulating on the outer surface 220 of the roller 22, reduce the risk of the roller 22 being stuck, so that the cleaning device 100 can be normally used.

[0033] In addition, the bracket 21 is rotatably installed on the chassis 102, and the roller 22 is rotatably installed on the bracket 21, so that the roller 22 can be flexibly moved and turned in different directions, adapt to various cleaning environments and ground conditions, and improve the applicability and cleaning efficiency of the cleaning device 100.

[0034] Specifically, the cleaning device 100 can be a sweeping robot, a mopping robot, a washing machine and the like. The chassis 102 is used to support and fix other components of the cleaning device 100, such as the roller assembly 20.

[0035] The roller assembly 20 can be used to realize the movement, turning or positioning of an object. The bracket 21 is a structure for fixing the roller 22 and supporting the rotation thereof, which can be made of metal, plastic or other solid materials to ensure the stability when the roller 22 rotates and bears a load. The bracket 21 can be provided with a shaft, a hole or the like structure for installing the roller 22. The bracket 21 can rotate relative to the chassis 102, which can be realized by a bearing or a shaft coupling or the like. The bracket 21 can drive the roller 22 to rotate relative to the chassis 102 in the process of rotating, so as to realize the turning function of the roller 22.

[0036] The roller 22 is a part of the roller assembly 20 that directly contacts with a moving surface, which can be single or multiple. The roller 22 can be made of wear-resistant materials such as rubber, polyurethane, plastic or metal to adapt to different loads and surface conditions. The roller 22 can rotate relative to the bracket 21. For example, the roller 22 can be rotatably installed on the bracket 21 in the mode of shaft-hole cooperation. For another example, the roller 22 can be rotatably installed on the bracket 21 in the mode of bearing connection. The outer surface 220 of the roller 22 refers to the surface of the roller 22 that contacts with the external environment.

[0037] In some embodiments, the roller assembly 20 further comprises a bearing. The bracket 21 is provided with a bearing seat or a bearing hole for installing the bearing. The bearing can be a ball bearing such as a deep groove ball bearing, which is suitable for bearing radial load and allowing the roller 22 to rotate smoothly. The roller 22 is connected with the bearing seat through an inner ring of the bearing, and an outer ring of the bearing is fixed on the bracket 21. The roller 22 and the bearing seat can be connected in the mode of interference fit or fastened by a bearing nut.

[0038] The cleaning member 40 can include a brush, a scraper, or the like. For example, the cleaning member 40 can include a fiber brush, a nylon brush, a wire brush, electrostatic bristles, or a plastic brush, or the like. For another example, the cleaning member 40 can include a plastic scraper, a rubber blade, or the like. Depending on the material and shape of the cleaning member 40, the cleaning member 40 is suitable for cleaning different types of winding objects. The number of the cleaning member 40 can be single or multiple.

[0039] The cleaning member 40 can be connected to the mounting portion 31 by means of bonding, clamping, clamping, adhesive fixing, or embedded fixing. For example, a groove can be provided on the mounting portion 31, and the cleaning member 40 can be embedded in the groove and then fixed by means of edge pressing or edge turning.

[0040] Contact refers to physical contact between the cleaning member 40 and the outer surface 220 of the roller 22. Through the contact, the cleaning member 40 can effectively remove the winding objects adhered to the outer surface 220 of the roller 22 during the rotation of the roller 22, thereby reducing the accumulation of winding objects on the roller 22, and further reducing the situation that the roller assembly 20 rotates unsmoothly or even jams. The cleaning member 40 can be in constant contact or timely contact with the outer surface 220 of the roller 22 to meet different use requirements.

[0041] In some embodiments, the cleaning member 40 is close to or in contact with the outer surface 220 of the roller 22 when the bracket 21 is within a certain angle range relative to the chassis 102; the cleaning member 40 is in contact with the outer surface 220 of the roller 22 when the bracket 21 rotates beyond the certain angle range relative to the chassis 102.

[0042] In this way, when the bracket 21 rotates beyond the certain angle range relative to the chassis 102, the bracket 21 drives the roller 22 to turn, the roller 22 is in a turning state, and the cleaning member 40 is kept apart from the outer surface 220 of the roller 22, which reduces the interference of the cleaning member 40 to the turning process of the roller 22 and maintains the flexibility of turning. When the bracket 21 is within the certain angle range relative to the chassis 102, the roller 22 is in a normal rotating state, and the cleaning member 40 is close to or in contact with the outer surface 220 of the roller 22. This allows the cleaning member 40 to remove the winding objects on the roller 22, thereby reducing the possibility of winding objects accumulating on the outer surface 220 of the roller 22, thereby reducing the risk of the roller 22 being jammed, and thereby allowing the normal use of the cleaning device 100.

[0043] Specifically, the rotation of the bracket 21 relative to the chassis 102 can be generated by means of an electric motor, a gas pump, or the like. The rotation of the bracket 21 relative to the chassis 102 means that the bracket 21 rotates about the shaft connected to the chassis 102, and such rotation allows the rollers 22 to guide the cleaning device 100 to turn on the ground. When the bracket 21 rotates, the cleaning member 40 is designed to keep a certain distance from the outer surface 220 of the rollers 22 and not to contact the rollers 22, so as to reduce the interference and additional resistance to the rollers 22 when turning.

[0044] The rotation of the bracket 21 relative to the chassis 102 within a certain angle range means that the bracket 21 does not rotate about the shaft connected to the chassis 102, and at this time, the rollers 22 are in a normal rotating state, and the rollers 22 guide the cleaning device 100 to move on the ground. In the case that the bracket 21 rotates relative to the chassis 102 within a certain angle range, the cleaning member 40 is designed to contact the outer surface 220 of the rollers 22, so as to remove the entanglements that can be entangled on the rollers 22. Since the entanglements usually have a certain volume, when the cleaning member 40 is arranged close to the outer surface 220 of the rollers 22, the cleaning member 40 can also effectively remove the entanglements adhered to the outer surface 220 of the rollers 22.

[0045] Please refer to Figure 2 In some embodiments, the cleaning member 40 is tangent to the outer surface 220 of the rollers 22.

[0046] In this way, the tangent design is conducive to reducing the influence of the cleaning member 40 on the rotation of the rollers 22, so that the cleaning member 40 can realize the cleaning of the entanglements without affecting the rotation of the rollers 22 as much as possible.

[0047] Specifically, the tangent contact mode minimizes the contact area, thereby reducing the friction and resistance when the rollers 22 rotate, while ensuring the effective cleaning of the entanglements.

[0048] In some embodiments, the cleaning member 40 is slightly in excess of the outer surface 220 of the rollers 22.

[0049] Please refer to Figure 1 and Figure 2 In some embodiments, the chassis 102 comprises a cover 30 and a mounting seat 10, the chassis 102 comprises the cover 30 and a mounting seat 10 connected to the cover 30, the bracket 21 is rotatably mounted on the mounting seat 10, the cover 30 is connected to the mounting seat 10, the cover 30 is provided with a mounting portion 31, the mounting portion 31 is arranged close to the rollers 22, and the cleaning member 40 is connected to the mounting portion 31.

[0050] In this way, the cleaning member 40 is easy to contact the rollers 22.

[0051] Specifically, the mounting base 10 is used to support and fix other components of the cleaning device 100, such as the cover 30 and the roller assembly 20, etc. The bracket 21 can rotate relative to the mounting base 10, which can be achieved by bearings or shaft couplings, etc. The bracket 21 can drive the roller 22 to rotate relative to the mounting base 10 in the process of rotation, so that the steering function of the roller 22 can be achieved.

[0052] The cover 30 and the mounting base 10 can be directly connected or indirectly connected. The cover 30 and the mounting base 10 can be detachably connected by bolt connection, clamping connection, etc., or can be non-detachably connected by riveting, welding, etc. For example, the cover 30 and the mounting base 10 can be provided with threaded holes, and the cover 30 and the mounting base 10 can be connected by bolts or screws. For another example, one of the cover 30 and the mounting base 10 can be provided with a buckle structure, and the other can be provided with a corresponding clamping hole structure, and the cover 30 and the mounting base 10 can be connected by the buckle structure and the clamping hole structure. The cover 30 and the mounting base 10 can also be an integrally formed structure.

[0053] The mounting portion 31 is a part of the cover 30 for connecting the cleaning piece 40. The distance between the mounting portion 31 and the roller 22 can be as small as possible, so that the cleaning piece 40 can be in contact with the outer surface 220 of the roller 22, and the size of the cleaning piece 40 can be reduced, thereby reducing the manufacturing cost of the cleaning piece 40.

[0054] Please refer to Figure 2 In some embodiments, the roller assembly 20 further includes a rotating shaft 23, one end of the rotating shaft 23 is fixedly connected with the bracket 21, the other end of the rotating shaft 23 is rotatably connected with the mounting base 10, a gap 101 is formed between the roller 22 and the cover 30, the gap 101 extends to the rotating shaft 23, and the cleaning piece 40 is located in the gap 101.

[0055] In this way, during the operation of the cleaning device 100, long and thin winding objects such as hair, fibers, and pet hair often accumulate on the roller 22. These winding objects can further move to the rotating shaft 23 through the gap 101 between the roller 22 and the cover 30, which can cause the rotating shaft 23 to rotate unevenly or even jam. By arranging the cleaning piece 40 in the gap 101, the winding objects accumulated on the roller 22 can be continuously cleaned, and the winding objects in the gap 101 can be effectively intercepted and cleaned, thereby reducing the possibility of the winding objects reaching the rotating shaft 23 through the gap 101.

[0056] In addition, the position of the mounting portion 31 and the existence of the gap 101 enable the cleaning piece 40 to be designed as a relatively simple structure and be easy to replace.

[0057] Specifically, the rotating shaft 23 is used to transmit power so as to enable the roller 22 to move or rotate. The power can be generated by a motor, a gas pump or the like driving device. The rotating shaft 23 can be fixedly connected with the support 21 by screwing, welding or the like. The rotating shaft 23 can rotate relative to the mounting base 10, which can be achieved by a bearing or a coupling or the like. For example, a connecting bearing 50 can be arranged between the rotating shaft 23 and the mounting base 10, and the rotating shaft 23 and the mounting base 10 can be rotatably connected through the connecting bearing 50.

[0058] In order to enable the roller 22 to rotate smoothly, a gap 101 is usually left between the roller 22 and the cover 30, that is, the gap 101 can provide a rotating space for the roller 22. However, as the winding object accumulates on the roller 22, the winding object can enter the rotating shaft 23 through the gap 101, thereby causing the rotating shaft 23 to jam or even be unable to rotate. Therefore, by arranging the cleaning piece 40 in the gap 101, that is, arranging the cleaning piece 40 between the roller 22 and the cover 30, the possibility of the winding object reaching the rotating shaft 23 through the gap 101 can be reduced.

[0059] Please refer to Figure 2 In some embodiments, the cleaning piece 40 includes a connecting portion 41 connected with the mounting portion 31 and a cleaning portion 42 connected with the connecting portion 41, the cleaning portion 42 is located in the gap 101, and in the case that the support 21 is within a certain angle range relative to the mounting base 10, the cleaning portion 42 is close to or contacts the outer surface 220 of the roller 22; in the case that the support 21 rotates beyond the certain angle range relative to the mounting base 10, the cleaning portion 42 is spaced from the outer surface 220 of the roller 22.

[0060] In this way, in the case that the support 21 rotates beyond the certain angle range relative to the mounting base 10, the support 21 drives the roller 22 to turn, the roller 22 is in a turning state, and the cleaning portion 42 is spaced from the outer surface 220 of the roller 22, which reduces the interference of the cleaning portion 42 to the turning process of the roller 22 and maintains the flexibility of turning. In the case that the support 21 is within the certain angle range relative to the mounting base 10, the roller 22 is in a normal rotating state, and the cleaning portion 42 is close to or contacts the outer surface 220 of the roller 22. This allows the cleaning portion 42 to remove the winding object on the roller 22, thereby reducing the possibility of the winding object accumulating on the outer surface 220 of the roller 22, reducing the risk of the roller 22 being stuck, and thus enabling the normal use of the cleaning device 100.

[0061] Specifically, the connecting portion 41 is a part of the cleaning piece 40 for connecting the cleaning portion 42 to the mounting portion 31. The connecting portion 41 can have a regular shape such as a block shape or a column shape, or can have an irregular shape. The connecting portion 41 can be connected to the mounting portion 31 by screwing, snap connection, adhesion, heat staking, or the like.

[0062] The cleaning portion 42 is a part of the cleaning piece 40 that directly contacts the outer surface 220 of the roller 22. The cleaning portion 42 can be connected to the connecting portion 41 by adhesion, heat staking, or the like. The cleaning portion 42 can be tangent to the outer surface 220 of the roller 22, slightly overfit, or the like. The cleaning portion 42 can extend from the connecting portion 41 toward the outer surface 220 of the roller 22. The cleaning portion 42 can scrape the outer surface 220 of the roller 22 and the area close to the outer surface during rotation of the roller 22 to remove the winding object.

[0063] The connecting portion 41 can be detachably mounted on the mounting portion 31 by screwing, snap connection, or the like, or can be mounted on the mounting portion 31 by adhesion, welding, or the like. For example, the connecting portion 41 is designed to have an internal thread. The mounting portion 31 is provided with a threaded hole that matches the thread of the connecting portion 41. The connecting portion 41 is screwed into the threaded hole of the mounting portion 31 by a screw.

[0064] For another example, the connecting portion 41 is designed to have a clamping groove. The mounting portion 31 is provided with a protrusion or a buckle that matches the clamping groove. The connecting portion 41 is aligned with the protrusion or the buckle on the mounting portion 31, and the buckle is locked with the clamping groove by pressing or buckling action to achieve fixation.

[0065] The cleaning portion 42 can extend from the connecting portion 41 toward the roller 22. The size of the cleaning portion 42 can be equal to or slightly smaller than the size of the gap 101, so as to effectively reduce the possibility of the winding object passing through the gap 101 to the rotating shaft 23.

[0066] Please refer to Figure 2 In some embodiments, the bracket 21 is provided with a fixing groove 210, and the rotating shaft 23 is embedded in the fixing groove 210.

[0067] In this way, by embedding the rotating shaft 23 in the fixing groove 210, the rotating shaft 23 can be provided with stable support, reducing the shaking of the rotating shaft 23 during rotation of the roller 22, thereby improving the stability of the rotating shaft 23. The connection mode of the embedding of the rotating shaft 23 in the fixing groove 210 does not require additional fasteners, thereby reducing the production cost and assembly complexity.

[0068] Specifically, the fixing groove 210 can be a groove designed on the bracket 21 for embedding the rotating shaft 23 to achieve the fixed connection between the rotating shaft 23 and the bracket 21. The fixing groove 210 can be arranged on the bracket 21 near one side of the rotating shaft 23. The fixing groove 210 can be a through groove or a blind groove, etc. For example, the fixing groove 210 can be a blind groove, thereby facilitating the positioning of the rotating shaft 23 during assembly. The rotating shaft 23 is embedded in the fixing groove 210, thereby being able to drive the bracket 21 to rotate relative to the chassis 102, thereby realizing the steering function of the roller 22.

[0069] Please refer to Figure 3 and Figure 4 In some embodiments, the bracket 21 is provided with two mounting grooves 211, which are arranged on both sides of the roller 22 in the axial direction. The roller 22 includes a main body part 221 and a protruding shaft 222 protruding on both sides of the main body part 221, and the protruding shaft 222 is inserted into the mounting groove 211.

[0070] In this way, the arrangement of the two mounting grooves 211 allows the roller 22 to have a certain floating space in the axial direction, which can adapt to different use conditions and ground inclinations, thereby improving the adaptability and flexibility of the roller assembly 20.

[0071] In addition, by arranging the mounting grooves 211 on both sides of the roller 22 in the axial direction and inserting the protruding shaft 222 of the roller 22 into the mounting grooves 211, more stable support can be provided, and the shaking of the roller 22 when moving on uneven ground under high load can be reduced. In addition, the design of inserting the protruding shaft 222 into the mounting groove 211 simplifies the installation process of the roller 22, which only needs to simply align the protruding shaft 222 with the mounting groove 211 and insert it, thereby facilitating quick assembly and maintenance.

[0072] Specifically, the mounting groove 211 can be two grooves arranged on the bracket 21. The two mounting grooves 211 can be symmetrically arranged to achieve symmetric installation of the roller 22. The mounting groove 211 is spaced from the fixing groove 210. The mounting groove 211 is used for fixing the protruding shaft 222, so that the main body part 221 can rotate relative to the protruding shaft 222 to realize the movement or steering of the roller 22, etc.

[0073] The main body part 221 of the roller 22 is the main part of the roller 22 for contacting the ground and supporting the load. The main body part 221 can be rotatably installed on the bracket 21. The number of protruding shafts 222 can be one or more to meet different load requirements. The protruding shaft 222 can be integrally formed with the main body part 221 or separately formed with the main body part 221. The protruding shaft 222 can be a regular shape such as a cylinder, a square, etc., or an irregular shape.

[0074] In some embodiments, the main body part 221 is provided with a through hole, and the protruding shaft 222 can be inserted into the through hole.

[0075] In some embodiments, the number of convex shafts 222 can be two, and the two convex shafts 222 are respectively connected to two sides of the body part 221.

[0076] In some embodiments, the rollers 22 are universal wheels. In this way, the universal wheels can rotate freely in multiple directions, significantly improving the maneuverability of the roller assembly 20, so that the cleaning device 100 can move flexibly in different directions.

[0077] Specifically, the universal wheels can rotate in any direction, providing omni-directional movement capability. The universal wheels can be spherical universal wheels, cage universal wheels, etc.

[0078] Please refer to Figure 2 In some embodiments, the cleaning member 40 is bonded to the chassis 102. In this way, by directly bonding the cleaning member 40 to the chassis 102, the installation process of the cleaning member 40 is simplified, without the need for additional mechanical fixation or complex installation steps, thereby reducing assembly cost and time.

[0079] Specifically, the cleaning member 40 can be bonded to the mounting part 31. The two side surfaces of the cleaning member 40 and the mounting part 31 adjacent to each other are bonded to each other. The cleaning member 40 can be bonded to the mounting part 31 by an adhesive. The adhesive can be dissolvable, which can facilitate replacement of the cleaning member 40. Of course, the cleaning member 40 can also be bonded to other areas of the chassis 102, and the embodiments of the present application do not limit this.

[0080] In some embodiments, the number of cleaning members 40 is multiple, and the multiple cleaning members 40 are in contact with the outer surface 220 of the roller 22.

[0081] In this way, the multiple cleaning members 40 can remove the entanglements on the outer surface 220 of the roller 22 in multiple areas, so that the entanglements on the outer surface 220 of the roller 22 can be more effectively removed, thereby improving the overall cleaning efficiency. In addition, the multiple cleaning members 40 can improve the reliability of the cleaning operation. When some of the cleaning members 40 fail to perform their cleaning function, other cleaning members 40 can still clean the entanglements, thereby reducing the occurrence of cleaning function failure.

[0082] Specifically, the number of cleaning members 40 can be two, three, four or even more. The multiple cleaning members 40 can be arranged at intervals on the chassis 102. The distance between the two adjacent cleaning members 40 can be equal, so that the outer surface 220 of the roller 22 can be more efficiently cleaned.
