[0008] Optionally, one end of the connecting arm away from the cleaning body has a circumferentially extending U-shaped notch, and the operating member is U-shaped and located at the U-shaped notch when it is in the first position. When the operating member drives the locking member to move to the second position, the operating member extends out of the U-shaped notch.

[0009] Optionally, the operating member is substantially parallel to the axial direction of the cleaning body when located at the second position.

[0010] Optionally, the cleaning body and the operating member are respectively located at two ends of the connecting arm.

[0011] Optionally, the U-shaped end of the operating member has an extrusion end, the locking member has a driving inclined surface, the operating member is rotatably connected to the connecting arm, and when the operating member rotates, the extrusion end squeezes the driving inclined surface and drives the locking member to move to the unlocking position.

[0021] The technical solution provided by the utility model has the following advantages:

[0022] 1) The utility model provides a locking member on the connecting arm. When the cleaning component is disassembled, the user rotates the operating member from the first position to the second position. At this time, the connecting arm needs to withstand the torque to overcome the rotation. If there is no locking member, the torque will be transmitted to the connection between the connecting arm and the roller, causing the roller and the connecting arm to loosen. However, due to the presence of the locking member, the utility model mainly concentrates the torque at the position of the locking member, so that there is basically no torque at the end of the connecting arm close to the cleaning main roller. Therefore, the cleaning component can not only be quickly installed and disassembled, but also ensure that the roller is not easy to loosen due to multiple disassemblies during long-term use, thereby improving the service life of the equipment;

[0023] 2) After the cleaning assembly of the utility model is fixed to the cleaning device by the locking member, the operating member is located in the U-shaped notch extending in the circumferential direction of the connecting arm. From the appearance, it forms a complete plane with the connecting arm. Compared with the prior art method of slotting the connecting arm to place the movable buckle, it is more concise and beautiful, and does not affect the cleaning effect of the cleaning device;

[0024] 3) When disassembling the cleaning component of the utility model, since the roller brush usually has a built-in motor, it is necessary to remove the roller brush along the axial direction. The utility model rotates the operating member to a second position substantially parallel to the cleaning body, so that after the user unlocks the cleaning component, the user can easily remove it from the cleaning device through the operating member, which is more convenient and labor-saving;

[0025] 4) The utility model fixes the cleaning component by both the locking member and the magnetic member, so that the cleaning component is fixed on the equipment more reliably. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all of the embodiments. The utility model will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0039] It should be noted that the terms "first", "second", etc. in the specification and claims of the utility model and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0040] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention.

[0041] In order to solve the problem of poor fixing reliability of components such as a roller brush of a cleaning device in the prior art, this embodiment provides a cleaning assembly and a cleaning device.

[0042] like Figures 1 to 9 A cleaning assembly shown in the figure includes a cleaning member 10 and a locking member 20. The cleaning member 10 includes a cleaning body 12 and a connecting arm 11. The cleaning body 12 can rotate around its own axis. One end of the connecting arm 11 is rotatably connected to the cleaning body 12, and the other end of the connecting arm 11 is detachably mounted on the cleaning device. When the user needs to clean or replace the cleaning body 12, the connecting arm 11 can be removed from the cleaning device so that the cleaning body 12 can be removed together with the connecting arm 11. The locking member 20 is movably connected to the connecting arm 11 and has a locking position for extending the connecting arm 11 and an unlocking position for retracting the connecting arm 11. The locking member 20 is located at an end of the connecting arm 11 that is not close to the cleaning body 12, so that when the connecting arm 11 is fixed on the cleaning device, the connecting arm 11 is subjected to relatively uniform force at various locations, so that the fixing of the cleaning body 12 is more reliable, and a good cleaning effect can still be guaranteed after long-term use.

[0043] In this embodiment, a locking member 20 is arranged on the connecting arm 11, and the locking member 20 can be switched between a locking position and an unlocking position. When the locking member 20 is in the locking position, at least a portion of the locking member 20 extends out of the connecting arm 11 so as to be able to extend into an external component, such as the base 50 of the cleaning device, so as to achieve the effect of fixing the cleaning component on the base 50. When disassembly is required, the locking member 20 only needs to be switched to the unlocking position so that the locking member 20 can be retracted into the connecting arm 11 and withdrawn from the base 50, so that the cleaning component can be quickly disassembled. The above-mentioned setting method enables the cleaning component 10 to be stably and reliably installed and fixed with the base 50 of the cleaning device through the locking member 20, and is convenient for disassembly, thereby ensuring the reliability of installation and fixing. Moreover, since the locking member 20 is connected to the connecting arm 11, the connection arm 11 has little effect in appearance and structure, thereby ensuring the integrity of the component, and avoiding the situation that the overall thickness of the connecting arm 11 increases due to the increase in structure, thereby increasing the space required for the end of the cleaning component and increasing the cleaning dead angle, thereby ensuring the cleaning ability of the cleaning component.

[0044] This embodiment is described by taking the cleaning component as a roller brush component and the cleaning device as a floor scrubber as an example. Accordingly, the cleaning body 12 is a roller brush, the base 50 of the cleaning device is the main body of the floor scrubber, and the roller brush is detachably matched with the main body. Of course, the cleaning device and the cleaning component can also be other devices or components.

[0045] like Figure 1As shown, in this embodiment, the projections of the locking member 20 and the cleaning body 12 do not overlap in the axial direction of the cleaning body 12. That is, the locking member 20 and the cleaning body 12 are arranged at different positions in the length direction of the connecting arm 11, and there is no overlap between the two, so that the arrangement of the locking member 20 does not affect the cleaning body 12, and the influence on other components is reduced while achieving fixed connection and convenient disassembly, thereby ensuring the integrity of the components.

[0046] The cleaning assembly of the present embodiment further comprises an operating member 30, which is movably connected to the connecting arm 11 and is in transmission connection with the locking member 20. The operating member 30 serves to allow personnel to operate and control the locking member 20. Since the operating member 30 is arranged on the peripheral side of the connecting arm 11 in the present embodiment, the operating member 30 will not affect the structure of the connecting arm 11 itself, and it is only necessary to add the operating member 30 on the peripheral side. At the same time, the operating member 30 has a first position and a second position, and the operating member 30 can rotate around the locking member 20 between the first position and the second position. When the operating member 30 rotates from the first position to the second position, the locking member 20 is driven to switch from the locked position to the unlocked position. In this way, when disassembly is required, the personnel only need to operate and rotate the operating member 30, and the locking member 20 can be switched to the unlocked position by the rotation of the operating member 30, and the cleaning assembly can be disassembled from the base 50. Of course, in addition to rotating the operating member 30, other settings may also be used, such as providing an extension arm connected to the locking member 20, and changing the position of the locking member 20 by pinching the extension arm.

[0047] like Figure 1 As shown, in this embodiment, the connecting arm 11 is in the shape of a long strip, and the cleaning body 12 and the operating member 30 are respectively located at the two ends of the connecting arm 11. In this way, on the one hand, there is a certain distance between the cleaning body 12 and the operating member 30, and the two are independent of each other and do not affect each other, ensuring that the two can perform their respective actions respectively. On the other hand, the operating member 30 is located at one end of the connecting arm 11 away from the cleaning body 12, so that the setting of the operating member 30 has little effect on the cleaning body 12 and the connecting arm 11, ensuring the integrity of the overall structure.

[0048] like Figure 2As shown, in this embodiment, when the operating member 30 is located at the first position, that is, when the locking member 20 is located at the locking position, the operating member 30 does not protrude from the outer surface of the connecting arm 11 . It should be noted that the outside and inside mentioned in this embodiment are relative to the base 50. The outside refers to the side away from the base 50, and the inside refers to the side close to the base 50. Therefore, the outer surface of the connecting arm 11 mentioned here refers to the side surface of the connecting arm 11 away from the base 50, that is, the exposed surface of the connecting arm 11. Therefore, the above-mentioned setting method means that when the operating member 30 is not operated, that is, when the cleaning assembly is installed on the base 50 through the locking member 20, the operating member 30 is located in the first position. At this time, the operating member 30 does not protrude from the connecting arm 11, and forms a complete plane with the connecting arm 11 from the appearance. Therefore, the setting of the operating member 30 does not affect the structure of the connecting arm 11, and does not affect the overall appearance of the connecting arm 11. Compared with the existing movable buckle method, it is more simple and beautiful, and it also avoids the situation where the thickness of the connecting arm 11 increases and the cleaning dead angle increases, thereby ensuring the good appearance and cleaning ability of the cleaning assembly.

[0049] Preferably, when the locking member 20 is in the locking position, the outer surface of the operating member 30 is parallel to the outer surface of the connecting arm 11. Furthermore, in this embodiment, the thickness of the operating member 30 is preferably substantially the same as the thickness of the connecting arm 11, or the thickness of the operating member 30 is less than the thickness of the connecting arm 11, so that the operating member 30 will neither protrude from the outer surface of the connecting arm 11 nor from the inner surface of the connecting arm 11, so that the thickness of the whole formed by the connecting arm 11 and the operating member 30 is not affected, reducing the impact of the added components on other structures of the cleaning device.

[0050] In order to reduce the protrusion of the operating member 30, the present embodiment has a circumferentially extending U-shaped notch at one end of the connecting arm 11 away from the cleaning body 12. Accordingly, the operating member 30 is U-shaped and arranged at the U-shaped notch. In this way, the shape of the operating member 30 is adapted to the shape of the U-shaped notch, so that when the operating member 30 is not operated and is located at the first position, the operating member 30 is located at the U-shaped notch and can just fill the vacant part of the connecting arm 11, so that the operating member 30 does not stand out on the connecting arm 11. When the cleaning body 12 needs to be disassembled, the operator moves the operating member 30 so that the operating member 30 extends out of the U-shaped notch and protrudes from the outer surface of the connecting arm 11. At this time, the operating member 30 moves to the second position and drives the locking member 20 to move to the unlocking position. At the same time, when the operating member 30 extends out of the U-shaped notch, since the operating member 30 is U-shaped, an angle is formed between the U-shape and the outer surface of the connecting arm 11, so that at this time, the operator can easily drive the connecting arm 11 and the cleaning body 12 to move together by operating the U-shaped operating member 30, thereby achieving the effect of removing the cleaning assembly from the base 50. Of course, the specific shape of the connecting arm 11 and the shape of the notch on the connecting arm 11 can be adjusted as needed, and are not limited to the U-shaped setting of this embodiment.

[0051] The operating member 30 of this embodiment is rotatably connected to the connecting arm 11. A rotating shaft is provided between the two ends of the U-shaped operating member 30. The axis of the rotating shaft is parallel to the line connecting the two ends of the U-shape and to the outer surface of the connecting arm 11. In this way, the operating member 30 can rotate around the rotating shaft. Figure 2 As shown in FIG. 1 , when the operating member 30 is not operated, the operating member 30 can be rotated into the U-shaped notch, and when the operating member 30 is moved, as shown in FIG. Fig. 9 As shown, the operating member 30 rotates around the rotating shaft by a certain angle, preferably 90 degrees, so that when the operating member 30 is in the second position, the operating member 30 is basically perpendicular to the outer surface of the connecting arm 11, that is, basically parallel to the axial direction of the cleaning body 12, and the operating member 30 can be maintained in the second position. In this way, the disassembly of the cleaning component conforms to the setting of the motor and other components in the cleaning equipment, so that after the user unlocks the cleaning component, the cleaning component can be easily pulled out from the base 50 through the operating member 30, which is more convenient, easy and labor-saving.

[0052] In addition to the above-mentioned arrangement of the rotation axis of the operating member 30 at the end of the U-shape, the position where the operating member 30 of this embodiment cooperates with the locking member 20 is also at the end of the U-shape. Specifically, the U-shaped end of the operating member 30 has an extrusion end 31, and the locking member 20 is movably arranged relative to the connecting arm 11. The moving trajectory of the locking member 20 is parallel to the outer surface of the connecting arm 11. The locking member 20 has a driving inclined surface 21, and the driving inclined surface 21 is inclined relative to the inner and outer surfaces of the connecting arm 11. In this way, when the operating member 30 rotates, the extrusion end 31 can squeeze the driving inclined surface 21, thereby driving the locking member 20 to move, and realizing that the locking member 20 moves to the unlocking position.

[0053] like Figures 3 to 5 As shown, in this embodiment, the locking member 20 has a protruding portion 22, and the protruding portion 22 can protrude from the connecting arm 11, so that the protruding portion 22 is a structure on the locking member 20 that cooperates with the base 50 to achieve external connection. When the locking member 20 is in the locking position, the protruding portion 22 protrudes from the circumferential side of the connecting arm 11, and when the locking member 20 is in the unlocking position, the protruding portion 22 retracts into the range of the connecting arm 11. Based on the upright manner of the connecting arm 11 in this embodiment, the protruding portion 22 protrudes from the circumferential side of the connecting arm 11, that is, protrudes from the upper side or the lower side of the connecting arm 11. Of course, based on different settings, the protruding portion 22 can also protrude from other sides, as long as it protrudes from the range of the connecting arm 11 so as to be able to cooperate with the base 50 in a limited manner. The driving bevel 21 and the protrusion 22 can be arranged at the same position of the locking member 20, or at different positions. In this embodiment, the driving bevel 21 and the protrusion 22 are arranged at the same end of the locking member 20, so that the extrusion end 31 of the operating member 30 squeezes the driving bevel 21 at the end of the locking member 20 to move the protrusion 22 back into the connecting arm 11.

[0054] In addition to the driving bevel 21, the locking member 20 of the present embodiment also has a reset bevel 23, which is arranged on the side of the protrusion 22 facing the base 50. In this way, when the cleaning component needs to be installed on the base 50, the cleaning component is gradually moved closer to the base 50 until the base 50 abuts against the reset bevel 23. At this time, force is continued to be applied, and the base 50 will squeeze the reset bevel 23, thereby driving the protrusion 22 to move, so that the protrusion 22 is temporarily retracted into the range of the connecting arm 11, so that the cleaning component can be installed in place. When the cleaning component is installed in place, the base 50 no longer squeezes the reset bevel 23, so that the protrusion 22 can extend out of the connecting arm 11 again, achieving a limited fit with the base 50, and completing the effect of fixing the cleaning component on the base 50.

[0055] Based on the functions of the above-mentioned reset slope 23 and the driving slope 21, along the direction from the outer surface to the inner surface of the connecting arm 11, the reset slope 23 is inclined toward the direction close to the center of the connecting arm 11, and the reset slope 23 is inclined toward the direction away from the center of the connecting arm 11, so that the inclination direction of the reset slope 23 is opposite to the inclination direction of the driving slope 21, so that the reset slope 23 and the driving slope 21 can play their respective roles. Of course, the protrusion 22 and the driving slope 21 can also be respectively arranged at different positions of the locking member 20, in which case the inclination relationship between the reset slope 23 and the driving slope 21 can be changed accordingly based on the change of their positions, as long as the respective functions of the two can be achieved.

[0056] In addition to the reset slope 23 on the locking member 20, an extrusion slope may also be provided on the extrusion end 31, that is, the extrusion end 31 has an extrusion slope, the extrusion slope contacts and cooperates with the driving slope 21, and the inclination direction of the extrusion slope is the same as that of the driving slope 21, so that when the operating member 30 rotates, the extrusion slope can squeeze the driving slope 21, so that the locking member 20 moves. The cooperation between the extrusion slope and the driving slope 21 increases the range of movement of the locking member 20 driven by the operating member 30, which is conducive to the rapid separation of the locking member 20 and the base 50. Of course, the extrusion end 31 can also directly adopt the structural form of a convex block, that is, the extrusion slope can be omitted.

[0057] During the rotation of the operating member 30, the operating member 30 can squeeze the driving inclined surface 21 to drive the locking member 20 to move during the entire rotation process, or it can drive the locking member 20 to move only in a part of the process, and the other process is the idling of the operating member 30. This embodiment adopts the latter. Specifically, taking the rotation of the operating member 30 by 90 degrees as an example, in the early stage of the rotation of the operating member 30, the operating member 30 drives the protrusion 22 of the locking member 20 to exit the base 50. At this time, the cleaning component has been separated from the base 50. With the operation of the operator, the operating member 30 continues to rotate. In the later stage of the rotation of the operating member 30, the operating member 30 idles, and the operating member 30 may not drive the locking member 20 to continue to move. In this way, the movement of the operating member 30 has a redundancy, thereby ensuring the reliability of the operating member 30 driving the locking member 20 to switch positions.

[0058] In this embodiment, there are multiple locking members 20, and the two sides of the connecting arm 11 opposite to each other in the circumferential direction are provided with locking members 20, and the movement directions of the locking members 20 on both sides are opposite. In this embodiment, two locking members 20 are provided, and the two locking members 20 are both provided on the inner surface of the connecting arm 11 and are located on the two sides of the connecting arm 11 opposite to each other in the circumferential direction, so that both sides of the connecting arm 11 are connected and fixed to the base 50 through the locking members 20, ensuring the stable and reliable connection and fixation between the connecting arm 11 and the base 50. Taking the connecting arm 11 standing vertically as an example, the locking members 20 are respectively provided on the upper side and the lower side of the connecting arm 11, and the movement directions of the two locking members 20 are opposite. The two locking members 20 are provided with driving inclined surfaces 21, so that they can cooperate with the two extrusion ends 31 at the U-shaped end of the operating member 30, so that the rotation of the operating member 30 can simultaneously drive the two locking members 20 to move closer to each other, so that the two locking members 20 can be retracted into the connecting arm 11 at the same time. Of course, the number of locking members 20 can be increased as needed, and more locking members 20 can be provided.

[0059] like Figure 3 and Figure 6 As shown, in this embodiment, the cleaning assembly further includes a reset member 40, which may be a spring or other component, and abuts against the locking member 20 to provide a reset force for the locking member 20 to move to the locked position. Since two locking members 20 are provided in this embodiment, two reset members 40 may also be provided, and the two reset members 40 respectively abut against and cooperate with the two locking members 20, thereby respectively providing a reset force to the locking members 20, or only one reset member 40 may be provided, and both ends of the reset member 40 abut against the two locking members 20 at the same time, so that the two locking members 20 have a tendency to move away from each other, and the two locking members 20 move to the locked position under the action of the reset member 40.

[0060] like Figure 6As shown, the connecting arm 11 of this embodiment has a limiting portion 13, which is arranged on the inner surface of the connecting arm 11 and forms an angle with the inner surface of the connecting arm 11. In this embodiment, the two are arranged vertically. The locking member 20 includes a main body, which is the main part of the locking member 20. The protruding portion 22 is located on the side of the main body facing the outside of the connecting arm 11, and the driving inclined surface 21 is located on the main body. In addition to the main body, the locking member 20 also includes an extension section 24, which is located on the side of the main body away from the protruding portion 22, so that the protruding portion 22 and the extension section 24 are located on opposite sides of the main body, and the extension section 24 is away from the protruding portion 22. The locking member 20 is provided with a stop hook 25 at the end of the extension section 24. The stop hook 25 is hooked and matched with the stop part 13, so as to provide a limit for the movement of the locking member 20 extending in the direction of the connecting arm 11. When the operating member 30 is reset and no longer presses the locking member 20, the locking member 20 automatically moves to the locking position under the action of the reset member 40 until the stop hook 25 is hooked and limited at the stop part 13. The locking member 20 can no longer extend further, so that the locking member 20 is kept in the locking position, avoiding the situation that the locking member 20 extends too far and the transmission relationship between the locking member 20 and the operating member 30 is lost and failure occurs, thereby ensuring the stability of the cooperation. Of course, the limit cooperation method between the connecting arm 11 and the locking member 20 is not limited to the above-mentioned setting method of this embodiment, and other cooperation methods can also be adopted, such as setting a slide rail structure and using the length of the slide rail structure to limit the movement range of the locking member 20.

[0061] The connecting arm 11 of this embodiment can adopt an integral component or a split structure. In this embodiment, the connecting arm 11 is divided into two parts, namely a connecting body and an end cover. The connecting body is the main part of the connecting arm 11, the operating member 30 and the locking member 20 are both arranged on the connecting body, and the end cover is arranged on the outer surface of the connecting body.

[0062] This embodiment also provides a cleaning device, including a base 50 and the above-mentioned cleaning assembly. The base 50 is the main part of the cleaning device. The motor, pipeline components, etc. are arranged in the base 50. When the cleaning assembly is installed on the base 50, the base 50 and the cleaning assembly are connected by transmission and pipeline, so that the base 50 can drive the cleaning body 12 of the cleaning assembly to move, and at the same time, the medium can be introduced into the cleaning body 12 to achieve cleaning and other operations. Figure 7As shown, in this embodiment, a mounting position 51 is provided on the side of the base 50, and the mounting position 51 can be a partially recessed structure. The end of the connecting arm 11 of the cleaning assembly away from the cleaning body 12 is detachably provided at the mounting position 51, so that the connecting arm 11 can be installed and accommodated in the base 50, and the connecting arm 11 is prevented from protruding too far. In this embodiment, a locking notch 52 is provided at the inner wall of the mounting position 51. Since there are two locking members 20, there are also two locking notches 52. The two locking notches 52 are respectively located on opposite sides of the mounting position 51, so as to cooperate with the two locking members 20 respectively. When the connecting arm 11 is installed at the installation position 51, the side wall of the installation position 51 squeezes the reset slope 23, so that the protrusion 22 temporarily retracts into the connecting arm 11 until the connecting arm 11 is installed in place at the installation position 51. At this time, the protrusion 22 extends out of the connecting arm 11 under the action of the reset member 40 and extends into the locking notch 52, thereby switching to the locking position. In this way, the connecting arm 11 can be installed and locked with the base 50 through the locking member 20, thereby realizing the installation of the cleaning component.

[0063] In addition to the above-mentioned locking member 20, in order to further improve the stability of the cooperation between the connecting arm 11 and the base 50, the cleaning device of this embodiment also includes a plurality of magnetic members 60, such as Figure 8 As shown, magnetic parts 60 are provided in both the connecting arm 11 and the base 50. Thus, when the connecting arm 11 is docked with the mounting position 51, the magnetic part 60 of the connecting arm 11 is magnetically positioned with the magnetic part 60 of the base 50, so that the connecting arm 11 is stably matched with the base 50 under the effect of magnetism, which not only provides a position reference for the installation of the connecting arm 11 and ensures accurate positioning during installation, but also further reduces shaking when the cleaning equipment is running, thereby ensuring stability during use. At the same time, the cleaning component is doubly fixed by the locking part 20 and the magnetic part 60, so that the fixing of the cleaning component on the base 50 is more reliable.

[0064] Since the operating member 30 is substantially flush with the connecting arm 11, when the connecting arm 11 is installed in the mounting position 51, the operating member 30 is also located in the mounting position 51. Therefore, in this embodiment, an operating slope 53 is provided on the side wall of the mounting position 51, and the operating member 30 of the cleaning assembly is spaced apart from the operating slope 53. In this way, the setting of the operating slope 53 forms an operating space at the mounting position 51 for a person to reach into, so that when a person operates the operating member 30, he or she can reach into the operating space and thus contact the inner side of the operating member 30, thereby facilitating the operation of rotating the operating member 30 outward.

[0065] In general, the installation and removal process of the cleaning assembly of this embodiment on the base 50 is as follows:

[0066] Installation process: Initially, the locking member 20 is in the locking position, and the operating member 30 is not operated but in the first position flush with the surface of the connecting arm 11. Align the cleaning body 12 with the installation position on the base 50, align the connecting arm 11 with the installation position 51, and gradually move the connecting arm 11 closer to the installation position 51. During the approaching process of the connecting arm 11, the side of the installation position 51 abuts against the reset slope 23 of the protrusion 22, and the protrusion 22 moves in the direction of retracting the connecting arm 11 under the abutment of the base 50, so that the locking member 20 temporarily switches to the unlocking position, until the connecting arm 11 is completely installed in the installation position 51, the protrusion 22 is aligned with the locking notch 52, and the side of the installation position 51 no longer presses the reset slope 23. The protrusion 22 extends out of the connecting arm 11 and extends into the locking notch 52 under the action of the reset member 40. The movement directions of the locking members 20 on both sides are the same, so that the connecting arm 11 is connected and fixed together by the locking member 20 and the base 50. When the connecting arm 11 is installed in the installation position 51 , the magnetic member 60 on the connecting arm 11 is magnetically adsorbed to the magnetic member 60 in the base 50 , so that the connecting arm 11 is stably maintained in the installation position 51 under the effect of magnetic adsorption.

[0067] Disassembly process: Initially, the locking member 20 is in the locking position, and the operating member 30 is not operated but in the first position flush with the surface of the connecting arm 11. During disassembly, the operator reaches into the operating space and touches the inner side of the operating member 30, and then pushes the operating member 30 outward to switch it to the second position. The operating member 30 rotates outward around the rotating axis under the push. During the rotation of the operating member 30, the extrusion end 31 of the operating member 30 squeezes the driving inclined surface 21 so that the locking member 20 moves to the unlocking position retracted in the connecting arm 11 until the protrusion 22 completely exits the locking notch 52. At this time, the operating member 30 may have been rotated to 90 degrees or may continue to rotate until it rotates 90 degrees. A vertical position relationship is formed between the operating member 30 and the connecting arm 11. Then the operator reaches into the U-shaped interior of the operating member 30, and pulls the connecting arm 11 and the cleaning body 12 out of the base 50 by hooking the U-shaped operating member 30, thereby realizing the disassembly of the cleaning assembly.

[0068] It should be noted that, in this embodiment, a plurality refers to at least two.

[0069] From the above description, it can be seen that the above embodiments of the utility model achieve the following technical effects:

[0070] 1. Solve the problem of poor fixing reliability of components such as roller brushes of cleaning equipment in the prior art;

[0071] 2. The cleaning parts can be stably and reliably installed and fixed to the base of the cleaning equipment through the locking parts, and are easy to disassemble, ensuring the reliability of installation and fixation;

[0072] 3. The setting of the operating parts will not have a great impact on the structure of the connecting arm, and has little impact on the appearance and structure of the parts, thus ensuring the integrity of the parts;

[0073] 4. It avoids the situation where the overall thickness of the connecting arm increases due to the increase in structure, thereby increasing the space required by the end of the cleaning component and increasing the cleaning dead angle, thereby ensuring the cleaning ability of the cleaning component.

[0074] Obviously, the above described embodiments are only a part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, ordinary technicians in this field can make other different forms of changes or modifications without creative work, which should fall within the scope of protection of the utility model.
