Description

Technical Field

[0001] This application belongs to the technical field of cleaning equipment, and particularly relates to a cleaning equipment and its cleaning head. Background Art

[0002] The cleaning head of the cleaning equipment is provided on a cleaning roller. When the cleaning equipment performs a cleaning operation, the cleaning roller rotates to clean the ground. For reasons such as cleaning, maintenance, or replacement, it is necessary to disassemble the cleaning roller.

[0003] One way to disassemble the cleaning roller is to fix the driving part to the cleaning head, and the rotating part is slidably sleeved on the driving part. The rotating part moves along the direction of its rotation axis and can be disassembled from the driving part. However, the rotating part generally needs to move the entire length of its axis to achieve disassembly or installation. Therefore, the disassembly and assembly of the cleaning head are still not convenient enough. Summary of the Invention

[0004] The purpose of the embodiments of this application is to provide a cleaning equipment and its cleaning head that can be disassembled and assembled conveniently and quickly.

[0005] On the one hand, the embodiments of this application provide a cleaning head of a cleaning equipment, including:

[0006] A housing, the housing includes a housing main body and a first connection seat and a second connection seat oppositely arranged on the housing main body;

[0007] A cleaning roller module, which is detachably connected to the housing. The cleaning roller module includes a driving component and a hollow drum. The driving component is assembled in the drum and is used to drive the drum to rotate relative to the driving component; wherein

[0008] At the first end of the cleaning roller module, the driving component is circumferentially fixedly connected to the first connection seat; at the second end of the cleaning roller module, the drum is rotatably matched with the second connection seat;

[0009] One of the first connection seat and the second connection seat is a movable connection seat, and the movable connection seat can move relative to the housing main body to provide an axial movement space for assembling the cleaning roller to the housing or removing it from the housing.

[0010] In an optional embodiment, the movable connection seat is detachably connected to the housing main body to provide an axial movement space for the cleaning roller module.

[0011] In an alternative embodiment, the movable connection seat includes a movable part and an elastic member. The movable part can move axially. The elastic member provides a force to keep the movable part in the first position. By overcoming the force of the elastic member, the movable part can move axially to provide an axial movement space for the cleaning roller module. When the cleaning roller module is assembled on the housing, the movable part remains in the first position.

[0012] In an alternative embodiment, the first connection seat has a first conductive terminal, and the drive assembly has a second conductive terminal. The first conductive terminal and the second conductive terminal respectively have a positive electrode and a negative electrode. When the cleaning roller assembly is assembled on the housing, the second conductive terminal is electrically connected to the first conductive terminal so that the power supply can provide power for the drive assembly.

[0013] In an alternative embodiment, the electrical connection between the first conductive terminal and the second conductive terminal includes at least one of plugging and abutting.

[0014] In an alternative embodiment, the positive and negative electrodes of the first conductive terminal and the second conductive terminal are respectively coaxially arranged, and the axes of the positive and negative electrodes of the second conductive terminal are collinear with the rotation axis of the cleaning roller module.

[0015] In an alternative embodiment, among the positive and negative electrodes of the first conductive terminal or the second conductive terminal, the one located inside is a pin or a jack, and the one located outside includes a ring-shaped conductive sheet.

[0016] In an alternative embodiment, an elastic conductive member is provided on the ring-shaped conductive sheet of one of the first conductive terminal and the second conductive terminal.

[0017] In an alternative embodiment, the first connection seat has a first guiding structure, and the drive assembly has a second guiding structure. When the cleaning roller assembly moves axially and the drive assembly is connected to the first connection seat, under the interaction of the second guiding structure and the first guiding structure, the drive assembly can rotate relative to the first connection seat to a preset position.

[0018] In an alternative embodiment, one of the first guiding structure and the second guiding structure is a guiding groove, and the other is a guiding block; the two wall surfaces of the guiding groove are spirally arranged in opposite directions so that the guiding groove gradually decreases along the assembly direction.

[0019] In an alternative embodiment, a positioning rib is provided in the guiding groove, and the drive assembly has a positioning groove. When the drive assembly rotates relative to the first connection seat to the preset position, the positioning rib faces the positioning groove, and the positioning rib slides into the positioning groove to fixedly connect the drive assembly and the first connection seat in a circumferential direction.

[0020] In an alternative embodiment, a positioning groove is further provided on one of the first connecting seat and the driving component provided with a guiding groove. The positioning groove communicates with the guiding groove. When the driving component rotates relative to the first connecting seat to a preset position, the guiding block faces the positioning groove, and the guiding block slides into the positioning groove to circumferentially and fixedly connect the driving component to the first connecting seat.

[0021] In an alternative embodiment, the cleaning roller module further includes a side cover. The side cover is connected to the roller to axially limit the driving component, and a bearing is provided between the side cover and the driving component.

[0022] In a second aspect, an embodiment of the present application provides a cleaning device, including the cleaning head according to any one of the above embodiments.

[0023] In the cleaning head of the cleaning device provided by the embodiment of the present application, the cleaning roller module includes a hollow roller and a driving component assembled in the roller. The driving component is used to drive the roller to rotate relative to the driving component. The cleaning roller module is detachably connected to the housing as a whole. In the embodiment of the present application, the roller and the driving component form a cleaning roller module. When the cleaning roller module is assembled to the housing or removed from the housing, only a small axial displacement is required, and the assembly and disassembly are more convenient and fast.

[0041] To keep the following description of the embodiments of this application clear and concise, detailed descriptions of known functions and known components are omitted in this application.

[0042] See Figures 1 to 10 , an embodiment of this application provides a cleaning head of a cleaning device, including a housing 1 and a cleaning roller module 2 provided on the housing 1.

[0043] The housing 1 is provided with an assembly chamber 12. The cleaning roller module 2 assembled on the housing 1 can be partially accommodated in the assembly chamber 12. For the cleaning head of a cleaning device with a vacuum adsorption function, the housing 1 is also provided with a suction interface 13 for communicating with a blower. Under the action of the blower, the gas in the assembly chamber 12 is pumped away, thereby generating a negative pressure in the assembly chamber 12. One side of the cleaning roller module 2 of the housing 1 that exposes the assembly chamber 12 forms a cleaning inlet. Under the action of the negative pressure, dirt such as dust enters the assembly chamber from the cleaning inlet and is output from the suction interface 13.

[0044] In an embodiment of this application, the housing 1 includes a housing main body 11 and a first connection seat 14 and a second connection seat 15 oppositely arranged on the housing main body 11. The first connection seat 14 and the second connection seat 15 are used to assemble the cleaning roller module 2 on the housing 1.

[0045] In the embodiment of the present application, the cleaning roller module 2 includes a driving component 21 and a hollow roller 22. The driving component 21 is assembled in the roller 22 and is used to drive the roller 22 to rotate relative to the driving component 21. The cleaning roller module 2 is detachably connected to the housing 1. The cleaning roller module 2 can be assembled as a whole to the housing 1 or disassembled from the housing 1. Compared with the need to move the entire axial length when disassembling the roller 22 alone, the cleaning roller module 2 in the embodiment of the present application only needs to move a smaller distance axially. The assembly and disassembly are more convenient and fast, improving work efficiency. At the same time, since the cleaning roller module 2 is integrated, it can effectively prevent broken garbage such as hair from entering the driving component 21, ensuring the cleanliness and high efficiency of the driving component 21.

[0046] In the embodiment of the present application, a first connection seat 14 and a second connection seat 15 are provided on the housing 1. The above two connection seats are respectively used to cooperate with both ends of the cleaning roller module 2 to assemble the cleaning roller module 2 on the housing 1. Among them, at the first end of the cleaning roller module 2, the driving component 21 is circumferentially fixedly connected to the first connection seat 14. At the second end of the cleaning roller module 2, the roller 22 is rotatably matched with the second connection seat 15. When the roller 22 is rotatably matched with the second connection seat 15 and the driving component 21 is circumferentially fixed to the first connection seat 14, when the driving component 21 drives the roller 22 to rotate, the driving component 21 is fixed relative to the housing 1, while the roller 22 can rotate around an axis.

[0047] In the embodiment of the present application, in order to facilitate the disassembly of the cleaning roller module 2, at least one of the first connection seat 14 and the second connection seat 15 can provide the moving space required for the disassembly and assembly of the cleaning roller module 2. The one of the first connection seat 14 and the second connection seat 15 that can provide the moving space required for the disassembly and assembly of the cleaning roller module 2 is used as the movable connection seat. The movable connection seat can move relative to the housing body 11 to provide axial moving space for the cleaning roller to be assembled to the housing 1 or removed from the housing 1. If one of the first connection seat 14 and the second connection seat 15 is the movable connection seat, it can provide the moving space required for the disassembly and assembly of the cleaning roller module 2. In an exemplary embodiment, only the second connection seat 15 can be the movable connection seat.

[0048] See Figure 2 、 Figure 5 and Figure 6 In the cleaning head of the cleaning device provided by the embodiment of the present application, the cleaning roller module 2 includes a hollow roller 22 and a driving component 21 assembled in the roller 22. The driving component 21 is used to drive the roller 22 to rotate relative to the driving component 21. The cleaning roller module 2 is detachably connected to the housing 1 as a whole. In the embodiment of the present application, the roller 22 and the driving component 21 form the cleaning roller module 2. When the cleaning roller module 2 is assembled to the housing 1 or removed from the housing 1, only a small axial displacement is required, and the assembly and disassembly are more convenient and fast.

[0049] In the embodiments of the present application, the specific manner in which the movable connection seat moves relative to the housing body 11 is not limited. Refer to Figure 3 and Figure 4 , in an exemplary embodiment, the movable connection seat can be removed from the housing 1, so as to provide the space required when the cleaning roller module 2 is assembled to the housing 1 or removed from the housing 1. Refer to Figure 10 . In another exemplary embodiment, the movable connection seat can also be a movable part 32 that can move relative to the housing 1 along the rotation axis of the drum 22. By moving the movable part 32 along the rotation axis of the drum 22, the space required when the cleaning roller module 2 is assembled to the housing 1 or removed from the housing 1 is provided.

[0050] Refer to Figure 3 and Figure 4 . In some embodiments, the movable connection seat is detachably connected to the housing body 11 to provide an axial movement space for the cleaning roller module 2. In an exemplary embodiment, after the movable connection seat is removed from the housing body 11, an opening is formed at the original position of the movable connection seat on the housing 1, and the cleaning roller module 2 can move axially through this opening. The installation method of the movable connection seat detachably connected to the housing body 11 is not limited. For example, the movable connection seat can be snap-connected to the housing body 11, connected by a threaded member, etc.

[0051] Taking the second connection seat 15 as the movable connection seat as an example, when disassembling the cleaning roller module 2, the cleaning roller module 2 moves in the direction of the second connection seat 15, and the movable part 32 is forced to move axially, thereby providing space for the disassembly of the cleaning roller module 2. After moving a certain distance, the driving assembly 21 is disconnected from the first connection seat 14. Tilt the cleaning roller module 2 to form a certain angle with the assembled state, and move the cleaning roller module 2 in the reverse direction, then the drum 22 can be disconnected from the second connection seat 15, so as to disassemble the cleaning roller module 2 from the housing 1.

[0052] Refer to Figure 10 . In some embodiments, the movable connection seat includes a movable part 32 and an elastic member 33. The movable part 32 can move axially, and the elastic member 33 provides a force to keep the movable part 32 in the first position. Overcoming the force of the elastic member 33 can make the movable part 32 move axially to provide an axial movement space for the cleaning roller module 2. When the cleaning roller module 2 is assembled to the housing 1, the movable part 32 is kept in the first position.

[0053] Taking the second connecting seat 15 as an example of the movable connecting seat again, when installing the cleaning roller module 2, the roller 22 of the cleaning roller module 2 is first connected to the second connecting seat 15, and then moved in the direction of the second connecting seat 15. The movable part 32 is forced to move axially, thereby providing space for the assembly of the cleaning roller module 2. After moving a certain distance, the driving component 21 of the cleaning roller module 2 is opposed to the first connecting seat 14. Move the cleaning roller module 2 in the direction of the first connecting seat 14 to fixedly connect the driving component 21 and the first connecting seat 14 in a circumferential direction. Under the action of the elastic member 33, the cleaning roller module 2 can be kept assembled on the housing 1.

[0054] See Figure 10 , in the embodiment of the present application, the movable connecting seat may further include a base 31. The base 31 has a sliding cavity for accommodating the movable part 32, and the movable part 32 can slide along the sliding cavity. An elastic member 33 is also provided in the sliding cavity, and both ends of the elastic member 33 act on the base 31 and the movable part 32 respectively.

[0055] The base 31 and the housing main body 11 may be an integral structure or a split structure. When the base 31 and the housing main body 11 are of a split structure, the base 31 can be fixedly connected to the housing main body 11 by means of threaded parts or snap connection.

[0056] When one of the first connecting seat 14 and the second connecting seat 15 is a movable connecting seat, the other may be an integral structure or a split structure with the housing main body 11. The connection methods in the case of a split structure include threaded part connection, snap connection, etc., which will not be elaborated here.

[0057] See Figure 4 , Figure 5 and Figure 7, in some embodiments, there is a circumferential fixing structure between the driving component 21 and the first connecting seat 14. In a specific implementation, the connection mode between the driving component 21 and the first connecting seat 14 can be keyway fit to achieve the circumferential fixed connection between the driving component 21 and the first connecting seat 14. One of the first connecting seat 14 and the driving component 21 is formed with an insertion part, and the other is formed with a corresponding receiving part. The receiving part is a connection hole axially opened. When the first connecting seat 14 and the driving component 21 are connected, the insertion part is inserted into the receiving part axially. One of the first connecting seat 14 and the driving component 21 is formed with a positioning key 41, and the other is formed with a corresponding positioning groove 42. When the insertion part is inserted into the receiving part axially, the positioning key 41 slides into the positioning groove 42 to achieve the circumferential fixed connection between the driving component 21 and the first connecting seat 14. For example, the first connecting seat 14 is formed with an insertion part, and the outer peripheral surface of the insertion part has a positioning groove 42. The end of the driving component 21 connected to the first connecting seat 14 has an axial connection hole to form a receiving part, and the inner peripheral surface of the receiving part has a positioning key 41. When the cleaning roller assembly moves axially and the receiving part of the driving component 21 is sleeved on the insertion part of the first connecting seat 14, the positioning key 41 slides into the positioning groove 42 to circumferentially fix the connection between the driving component 21 and the first connecting seat 14. The specific settings of the positioning key 41 and the positioning groove 42 will be further described in the following embodiments when the circumferential fixing structure is involved.

[0058] In some embodiments, the first connecting seat 14 has a first conductive terminal 16, and the driving component 21 has a second conductive terminal 24. The first conductive terminal 16 and the second conductive terminal 24 respectively have a positive electrode and a negative electrode. When the cleaning roller assembly is assembled on the housing 1, the second conductive terminal 24 is electrically connected to the first conductive terminal 16 so that the power supply can provide power for the driving component 21. In the embodiments of the present application, conductive terminals are respectively arranged on the first connecting seat 14 and the driving component 21. When the cleaning roller assembly is assembled on the housing 1, the conductive terminals arranged on both the first connecting seat 14 and the driving component 21 are electrically connected, enabling the power supply to provide power for the driving component 21. Moreover, the first conductive terminal 16 and the second conductive terminal 24 can be separated, without affecting the removal of the cleaning roller module 2 from the housing 1.

[0059] The power supply for supplying power to the driving component 21 can be a battery. Using a battery as the power supply, when the cleaning device is working, there is no restraint of cables, making it more convenient to use. The battery as the power supply can be various types of rechargeable batteries. Of course, the embodiments of the present application do not exclude an external power supply for supplying power to the driving component 21.

[0060] In some embodiments, the electrical connection between the first conductive terminal 16 and the second conductive terminal 24 includes at least one of plugging and abutting. The electrical connection methods of plugging or abutting facilitate the disassembly and assembly of the cleaning roller module 2. As long as the positive and negative poles of the first conductive terminal 16 and the second conductive terminal face each other, the electrical connection or disconnection between the first conductive terminal 16 and the second conductive terminal can be completed during disassembly and assembly.

[0061] In an exemplary embodiment, the positive and negative poles of both the first conductive terminal 16 and the second conductive terminal can adopt the same electrical connection method. For example, both the positive and negative poles adopt the plugging method, or both adopt the abutting method.

[0062] Of course, the positive and negative poles of both the first conductive terminal 16 and the second conductive terminal can also adopt different electrical connection methods. For example, one of the positive and negative poles adopts plugging, while the other adopts abutting.

[0063] The specific structure of plugging and the specific structure of abutting can be exemplarily illustrated through the following embodiments.

[0064] See Figure 8 and Figure 9 In some embodiments, the positive and negative poles of the first conductive terminal 16 and the second conductive terminal 24 are respectively coaxially arranged. The axes of the positive and negative poles of the second conductive terminal 24 are collinear with the rotation axis of the cleaning roller module 2. The positive and negative poles of the first conductive terminal 16 and the second conductive terminal 24 are respectively coaxially arranged and collinear with the rotation axis of the cleaning roller module 2. When assembling the cleaning roller module 2, there is no need to consider whether the positive and negative poles of the first conductive terminal 16 and the second conductive terminal correspond to each other. After the driving assembly 21 is connected to the first connecting seat 14, the electrodes located inside will necessarily be connected to the electrodes located inside, and the electrodes located outside will necessarily be connected to the electrodes located outside.

[0065] For example, on the first conductive terminal 16 and the second conductive terminal 24, the positive pole is located inside and the negative pole is located outside, and the two are coaxial. After the driving assembly 21 is connected to the first connecting seat 14, the positive poles of the first conductive terminal 16 and the second conductive terminal 24 are connected to each other, and the negative poles are connected to each other.

[0066] In the embodiments of the present application, among the above-mentioned coaxially arranged positive and negative poles, the electrical connection methods can be the same or different.

[0067] Taking the electrodes as plugging as an example, in the first conductive terminal 16 and the second conductive terminal 24, the structure of one of them is a cylindrical structure, and the inner and outer circumferential surfaces of the cylindrical structure respectively form the positive and negative poles. The other includes an electrode hole and an electrode post located in the electrode hole, and the inner wall surface of the electrode hole and the outer wall surface of the column body respectively form the positive and negative poles. After the driving assembly 21 is connected to the first connecting seat 14, the outer circumferential surface of the cylindrical structure is electrically connected to the inner wall surface of the electrode hole, and the inner circumferential surface of the cylindrical structure is electrically connected to the outer wall surface of the electrode post.

[0068] Taking one of the positive and negative electrodes as the plug-in and the other as the abutment as an example. The one located inside can be the plug-in. One of the first conductive terminal 16 and the second conductive terminal 24 is the plug-in part and the other is the connection part. For example, the connection mode of the pin 242 and the jack 162. The one located outside can be the abutment. Specifically, the following embodiments can be used to illustrate different connection modes for the positive and negative electrodes.

[0069] See Figure 8 and Figure 9 , in some embodiments, among the positive and negative electrodes of the first conductive terminal 16 or the second conductive terminal 24, the one located inside is the pin 242 or the jack 162, and the one located outside includes an annular conductive sheet. For example, the first connection base 14 has a jack 162 located inside and a first annular conductive sheet 161 located outside, and the two are coaxially arranged. Correspondingly, the driving assembly 21 has a pin 242 located inside and a second annular conductive sheet 241 located outside, and the two are coaxially arranged. The pin 242 and the jack 162 can be the opposite positive electrodes or the opposite negative electrodes. When the driving assembly 21 is connected to the first connection base 14, the pin 242 is plugged into the jack 162, and the first annular conductive sheet 161 abuts against the second annular conductive sheet 241.

[0070] In another exemplary case, it can also be that the first connection base 14 has a pin 242 located inside and a first annular conductive sheet 161 located outside, and the two are coaxially arranged. Correspondingly, the driving assembly 21 has a jack 162 corresponding to the pin 242, and the jack 162 is coaxially arranged with the driving assembly 21. Another electrode on the driving assembly 21 can be a non-annular conductive sheet, and its distance from the jack 162 is equal to the radius of the first annular conductive sheet 161. When the driving assembly 21 is connected to the first connection base 14, there is no requirement for the circumferential correspondence between the driving assembly 21 and the first connection base 14. After the driving assembly 21 is connected to the first connection base 14, the electrodes of the two are necessarily electrically connected.

[0071] In some embodiments, an elastic conductive member 163 is provided on the annular conductive sheet of one of the first conductive terminal 16 and the second conductive terminal 24. The provision of the elastic conductive member 163 can ensure the stability of the electrical connection during abutment.

[0072] In the embodiments of the present application, the elastic conductive member 163 can be selected from a conductive spring or a conductive elastic sheet.

[0073] See Figure 6 and Figure 7, in some embodiments, the first connecting seat 14 is provided with a first guiding structure 141, and the driving component 21 is provided with a second guiding structure 211. When the cleaning roller assembly moves axially and the driving component 21 is connected to the first connecting seat 14, under the interaction of the second guiding structure 211 and the first guiding structure 141, the driving component 21 can rotate relative to the first connecting seat 14 to a preset position. In the embodiments of the present application, corresponding guiding structures are respectively provided on the first connecting seat 14 and the driving component 21. During the process of axially moving the driving component 21 to be assembled to the first connecting seat 14, the guiding structures between the first connecting seat 14 and the driving component 21 interact, enabling the driving component 21 to rotate relative to the first connecting seat 14 to a specific position. This structure can simplify the assembly of the cleaning roller module 2 without considering whether the first conductive terminal 16 and the second conductive terminal 24 correspond, nor considering whether the circumferential fixing structure (such as a keyway structure) between the first connecting seat 14 and the driving component 21 corresponds. Under the action of the guiding structure, the driving component 21 is guided to a specific corresponding position relative to the first connecting seat 14. This position can be the position where the first conductive terminal 16 and the second conductive terminal 24 correspond, or the position where the circumferential fixing structure between the first connecting seat 14 and the driving component 21 corresponds.

[0074] By providing the first guiding structure 141 on the first connecting seat 14 and the second guiding structure 211 on the driving component 21, the specific structure of the electrodes on the first conductive terminal 16 and the second conductive terminal 24 can be more widely selected without increasing the assembly difficulty. In an exemplary embodiment, both the positive and negative electrodes adopt a pin 242 - socket 162 structure. For example, two sockets 162 are provided on the first connecting seat 14, and two pins 242 are provided on the driving component 21. Taking the pins 242 on the driving component 21 as an example, there are no special requirements for the positions of the two pins 242. They can be symmetrically arranged relative to the axis or arranged randomly. The guiding mechanism can make the electrodes on the first conductive terminal 16 and the second conductive terminal 24 correspond.

[0075] See Figure 6 and Figure 7 , in some embodiments, one of the first guiding structure 141 and the second guiding structure 211 is a guiding groove, and the other is a guiding block. Figure 6 In the illustrated embodiment, the first guiding structure 141 on the first connecting seat 14 is a guiding groove. The two wall surfaces of the guiding groove are spirally arranged in opposite directions so that the guiding groove gradually decreases along the assembly direction. In the embodiments of the present application, when the cleaning roller module 2 moves axially and the driving component 21 is assembled to the first connecting seat 14, the guiding block will slide along the wall surface of the guiding groove, causing the driving component 21 to rotate relative to the first connecting seat 14 until the guiding block slides to the end of the guiding groove.

[0076] In the embodiments of the present application, the first guiding structure 141 may be a guiding groove, and the second guiding structure 211 may be a guiding block. Or the first guiding structure 141 may be a guiding block, and the second guiding structure 211 may be a guiding groove. Taking the first connecting seat 14 having an insertion portion and the driving assembly 21 having a receiving portion as an example, a guiding groove is provided on the outer peripheral surface of the insertion portion, and a guiding block is provided on the inner peripheral surface of the receiving portion.

[0077] In the embodiments of the present application, a circumferential fixing structure is provided between the first connecting seat 14 and the driving assembly 21. When the circumferential fixing structure is a keyway structure, the circumferential fixing structure may include a positioning groove 42 and a positioning key. One of the positioning groove 42 and the positioning key is provided on the first connecting seat 14, and the other is provided on the driving assembly 21.

[0078] The specific positions, numbers, shapes, sizes, etc. of the positioning groove 42 and the positioning key are not limited. For example, only the positioning groove or the positioning key may be provided on the first connecting seat 14, and the corresponding positioning key or positioning groove is provided on the driving assembly 21. Or, both the positioning groove and the positioning key may be provided on the first connecting seat 14, and the driving assembly 21 also has the corresponding positioning key and positioning groove. Specifically, it can be further exemplarily described in the following embodiments.

[0079] In some embodiments, the guiding structure may be combined with the circumferential fixing structure, and the two structures may share one or several identical components. For example, a positioning groove 42 is also provided on the one of the first connecting seat 14 and the driving assembly 21 where the guiding groove is provided. Refer to Figure 7 In the illustrated embodiment, a guiding groove and a positioning groove 42 are provided on the first connecting seat 14. The positioning groove 42 communicates with the guiding groove. When the driving assembly 21 rotates relative to the first connecting seat 14 to a preset position, the guiding block is opposite to the positioning groove 42, and the guiding block slides into the positioning groove 42 to circumferentially fixedly connect the driving assembly 21 and the first connecting seat 14. In the embodiments of the present application, the guiding block in the guiding structure cooperates with the guiding groove to achieve guiding. At the same time, in the circumferential positioning structure, the guiding block serves as a positioning key 41 in the keyway structure to cooperate with the positioning groove 42 to achieve the circumferential fixed connection between the driving assembly 21 and the first connecting seat 14.

[0080] In the embodiments of the present application, the guiding structure and the circumferential fixing structure may be separately provided. The guiding structure is mainly used to guide the driving assembly 21 to rotate relative to the first connecting seat 14 to a specific position.

Of course, it can also be a combination of the above two methods or other forms to make the two axially relatively fixed.

[0086] In an exemplary embodiment, when a bearing 25 is provided between the roller 22 and the driving assembly 21, the inner ring of the bearing 25 and the driving assembly 21 can be fixedly connected by interference fit, and the frictional force between the inner ring and the driving assembly 21 at least ensures that when the cleaning roller module 2 is normally assembled to the housing 1 or disassembled from the housing 1, the two will not be displaced. The outer ring of the bearing 25 and the roller 22 can also be fixedly connected by interference fit. The frictional force between the outer ring and the roller 22 at least ensures that when the cleaning roller module 2 is normally assembled to the housing 1 or disassembled from the housing 1, the two will not be displaced.

[0087] In some embodiments, the cleaning roller module 2 further includes a side cover 23. The side cover 23 is connected to the roller 22 to axially limit the driving assembly 21, and a bearing 25 is provided between the side cover 23 and the driving assembly 21. Providing the side cover 23 can make the roller 22 and the driving assembly 21 axially relatively fixed. And it is convenient for the assembly of the cleaning roller module 2.
