[0068] Embodiments of the present invention are described in detail below, and the embodiments described with reference to the accompanying drawings are exemplary.

[0069] Reference below Figure 1-Figure 14 The cleaning assembly 200 of the cleaning device 100 according to the embodiment of the utility model is described. The cleaning assembly 200 includes a disassembly mechanism 20 , which can enable the cleaning device 100 to automatically disassemble the cleaning member 30 , thereby improving the automation level of the cleaning device 100 .

[0070] Combination Figure 1-Figure 14 As shown, the disassembly mechanism 20 according to the first embodiment of the utility model includes a driving device, a cleaning member 30 and a connecting member 21.

[0071] The disassembly mechanism 20 can disassemble and separate the cleaning member 30 from the connecting member 21 according to the disassembly and assembly requirements (such as when the cleaning device 100 has a cleaning member 30). The cleaning member 30 is mainly used to clean dirt on the working surface. For example, the cleaning member 30 can be a rag plate. The driving device can drive the connecting member 21 to move.

[0072] Specifically, the connecting member 21 and the cleaning member 30 are detachably connected, and the driving device can drive the connecting member 21 to move; wherein, during the movement, the connecting member 21 has a first stroke and a second stroke, in which the cleaning member 30 and the connecting member 21 remain connected in the first stroke, and in the second stroke, the cleaning member 30 and the connecting member 21 are separated.

[0073] In detail, when the disassembly mechanism 20 performs the work of disassembling the cleaning member 30, the driving stroke of the driving device for the connecting member 21 includes a first stroke and a second stroke. That is, in the first stroke, the driving device can drive the connecting member 21 to move toward a side away from or close to the cleaning member 30, thereby achieving the effect of gradually tightening the connecting member 21 to the cleaning member 30 (at this time, the cleaning member 30 is connected to the connecting member 21, and is in a trend of being fixed more and more tightly) or gradually separating the connecting member 21 from the cleaning member 30 (at this time, the cleaning member 30 is still connected to the connecting member 21, but is in a trend of being separated); in the second stroke, the cleaning member 30 and the connecting member 21 have been separated from each other, thereby achieving the effect of automatic disassembly of the cleaning member 30.

[0074] Optionally, the driving device can drive the connecting member 21 and the cleaning member 30 to move, and the connecting member 21 and the cleaning member 30 generate a displacement difference during the movement, so that the connecting member 21 and the cleaning member 30 are separated. In other words, a detachable connection relationship can be flexibly established between the connecting member 21 and the cleaning member 30. When the user needs to disassemble the cleaning member 30, the power source 10 drives the connecting member 21 and the cleaning member 30 to move relative to each other, thereby achieving an effect of gradually increasing the distance between the two, thereby achieving an automatic disassembly effect of the cleaning member 30.

[0075] For example, when the cleaning device 100 is in a non-base station working environment, the driving device can drive the connecting member 21 and the cleaning member 30 to move in the first direction, but the speeds of the two moving in the first direction are different, so that the distance between the two gradually increases until they are separated from each other; for another example, when the cleaning device 100 is placed in a base station, the base station is provided with a disassembly position, at which time the cleaning member 30 and the connecting member 21 move in different directions (such as the connecting member 21 moves upward, and the cleaning member 30 moves downward), so that the distance between the two can be gradually increased until they are separated from each other, thereby achieving the effect of the cleaning member 30 automatically separating from the cleaning device 100. (Wherein, the moving directions of the connecting member 21 and the cleaning member 30 are not limited, and the two move with a gradually increasing relative distance)

[0076] Among them, when the cleaning member 30 establishes a connection relationship with the connecting member 21, the cleaning member 30 is connected to the connecting member 21, and the distance between the two can be 0. The two can be bonded or magnetically attracted, so that the cleaning member 30 is in a state of being installed on the cleaning device 100; when the distance between the cleaning member 30 and the connecting member 21 is far, the cleaning member 30 is in a disassembled state, and the cleaning member 30 can be automatically removed from the cleaning device 100 under the action of gravity.

[0077] In addition, compared to traditional fixed cleaning parts that need to be manually disassembled, such as a rag plate (the user will inevitably touch the rag plate with dirt on it when removing the rag plate), the present application can prevent the user's hands from directly touching the dirty rag plate, thereby effectively improving the user's experience.

[0078] Therefore, by providing the disassembly mechanism 20, the cleaning device 100 can automatically disassemble the cleaning member 30, thereby improving the automation level of the cleaning device 100, simplifying user-side operations, and improving user experience.

[0079] According to some optional embodiments of the present invention, combined with Figure 4-Figure 6 As shown, the connecting member 21 is provided with a first magnetic adsorption member 213, and the cleaning member 30 is provided with a second magnetic adsorption member 31; in the first stroke, the magnetic force between the first magnetic adsorption member 213 and the second magnetic adsorption member 31 is greater than the gravity of the cleaning member 30, and in the second stroke, the magnetic force between the first magnetic adsorption member 213 and the second magnetic adsorption member 31 is less than the gravity of the cleaning member 30.

[0080] Specifically, the connecting member 21 and the cleaning member 30 are provided with a first magnetic adsorption member 213 and a second magnetic adsorption member 31 respectively. The first magnetic adsorption member 213 on the connecting member 21 and the second magnetic adsorption member 31 on the cleaning member 30 can attract each other to generate magnetic attraction.

[0081] For example, when the connecting member 21 is in the first stroke, since the distance between the first magnetic adsorption member 213 and the second magnetic adsorption member 31 is relatively close, the magnetic force between the first magnetic adsorption member 213 on the connecting member 21 and the second magnetic adsorption member 31 on the cleaning member 30 is greater than the gravity of the cleaning member 30. In this way, the cleaning member 30 can maintain the effect of being connected to the connecting member 21, thereby ensuring the working stability of the cleaning member 30 when performing cleaning work.

[0082] For another example, when the connecting member 21 is in the second stroke, since the distance between the first magnetic adsorption member 213 and the second magnetic adsorption member 31 is relatively far, the magnetic force between the first magnetic adsorption member 213 on the connecting member 21 and the second magnetic adsorption member 31 on the cleaning member 30 is smaller than the gravity of the cleaning member 30, so that the cleaning member 30 can be detached from the connecting member 21, thereby achieving the automatic disassembly effect of the disassembly mechanism 20 on the cleaning member 30. For example, the first magnetic adsorption member 213 can be a magnet, and the second magnetic adsorption member 31 can be a metal member, but it is not limited thereto.

[0083] According to some optional embodiments of the present invention, combined with Figure 2-Figure 6 As shown, the driving device includes a power source 10, a transmission member 22 and a limit member 23, the transmission member 22 is transmission-connected to the power source 10, and the limit member 23 is limitedly matched with the cleaning member 30; wherein, in the first stroke, the limit member 23 and the transmission member 22 are transmission-connected and the connecting member 21 and the cleaning member 30 remain connected and move together with the cleaning member 30, and in the second stroke, the limit member 23 and the connecting member 21 are transmission-connected to the transmission member 22 respectively and the limit member 23 and the connecting member 21 generate a displacement difference during the movement so that the connecting member 21 and the cleaning member 30 are separated.

[0084] The power source 10 can provide driving force to the transmission member 22. The limiting member 23 and the cleaning member 30 are limited in the axial direction (that is, the up and down direction), so that the movement of the cleaning member 30 in the axial direction can be limited, which is conducive to ensuring that a distance difference is formed between the cleaning member 30 and the connecting member 21, thereby ensuring that the cleaning member 30 can be smoothly disassembled and installed.

[0085] Moreover, when the connecting member 21 is in the first stroke, the power source 10 transmits the driving force to the transmission member 22, and the transmission member 22 and the limit member 23 are mutually transmitted, and the transmission member 22 and the limit member 23 are in a limit matching relationship, so the limit member 23 moves synchronously with the transmission member 22, but at this time the connecting member 21 and the cleaning member 30 are still maintained in a connected state; when the connecting member 21 is in the second stroke, as the power source 10 continues to drive the transmission member 22 to move, the transmission member 22 still maintains a transmission connection relationship with the transmission member 22, and the connecting member 21 also transmits mutually with the transmission member 22, so that the connecting member 21 and the limit member 23 produce a displacement difference during the transmission process with the transmission member 22, and the cleaning member 30 is limited by the limit member 23, so as the distance between the connecting member 21 and the cleaning member 30 gradually increases, the cleaning member 30 achieves the effect of detaching from the connecting member 21.

[0086] In addition, after the power source 10 transmits power to the transmission member 22, the transmission member 22 is respectively connected to the limit member 23 and the connecting member 21 for transmission, so that the power source 10 can selectively indirectly control the displacement difference generated by the limit member 23 and the connecting member 21, thereby achieving the effect of controlling the displacement difference between the connecting member 21 and the cleaning member 30 (due to the limiting cooperation between the limit member 23 and the cleaning member 30), thereby realizing the effect of automatically disassembling and installing the cleaning member 30.

[0087] In particular, when the cleaning member 30 needs to be disassembled, the transmission member 22 drives the connecting member 21 and the limiting member 23 to move upward, and within a unit time, the distance that the limiting member 23 moves upward is smaller than the distance that the connecting member 21 moves upward. In this way, the distance between the cleaning member 30 that is limited by the connecting member 21 and the limiting member 23 can be increased, so that the cleaning member 30 is switched from the installed state to the disassembled state, thereby achieving the effect of automatic disassembly of the cleaning member 30.

[0088] Optionally, combined Figure 3-Figure 6 , Figure 9-11 and Fig.13 As shown, in the second stroke, the power source 10 can drive the driving transmission member 22 to drive the connecting member 21 and the limiting member 23 to move in the same direction, and the moving distance of the connecting member 21 per unit time is greater than the moving distance of the limiting member 23.

[0089] The power source 10 is connected to the transmission member 22 in a transmission manner, and the power source 10 can drive the connection member 21 and the limit member 23 to move in the same direction (such as Figure 2 The connecting member 21 and the limiting member 23 move in the first direction (in the up and down direction, which can also be the direction of the rotation axis of the connecting member 21), and the displacement values ​​of the connecting member 21 and the limiting member 23 moving toward the first direction are different, so the connecting member 21 and the limiting member 23 have a displacement difference in the first direction (and because the cleaning member 30 cooperates with the limiting member 23 in the first direction), so that the distance between the connecting member 21 and the cleaning member 30 in the first direction gradually increases, thereby achieving the effect of automatically assembling and disassembling the connecting member 21 and the cleaning member 30.

[0090] In addition, the limiting member 23 and the cleaning member 30 are limited in the first direction, so that the movement of the cleaning member 30 in the axial direction can be limited, which is beneficial to ensure that a displacement difference is formed between the cleaning member 30 and the connecting member 21, thereby ensuring that the cleaning member 30 can be disassembled smoothly.

[0091] Furthermore, the transmission member 22 is a rotating member, and when the transmission member 22 rotates, the connecting member 21 and the limiting member 23 move in the first direction.

[0092] The connecting member 21 and the limiting member 23 are respectively connected to the transmission member 22 in a transmission manner. As the transmission member 22 rotates, the connecting member 21 and the limiting member 23 are connected to the transmission member 22 in a first direction (eg Figure 2 The connecting member 21 and the limiting member 23 have the same moving direction relative to the transmission member 22 (the up and down directions shown in the figure, the direction of the rotation axis of the transmission member 22, etc.). Since the bottom of the cleaning member 30 is stopped by the cleaning working surface, when the connecting member 21 and the limiting member 23 are moving upward, the distance between the cleaning member 30 and the connecting member 21 can be increased at the same time, thereby smoothly completing the disassembly and separation work of the cleaning member 30, thereby improving the scientificity and rationality of the arrangement.

[0093] Specifically, combined Figure 2-Figure 8 , Figure 9-11 and Fig.13 As shown, the transmission member 22 is provided with a first threaded portion 221 and a second threaded portion 222, the connecting member 21 is provided with a third threaded portion 211, and the limiting member 23 is provided with a fourth threaded portion 231, the first threaded portion 221 cooperates with the third threaded portion 211, and the second threaded portion 222 cooperates with the fourth threaded portion 231; in the first stroke, the first threaded portion 221 is separated from the third threaded portion 211, and in the second stroke, the first threaded portion 221 cooperates with the third threaded portion 211; wherein the pitch of the first threaded portion 221 and / or the third threaded portion 211 is greater than the pitch of the second threaded portion 222 and / or the fourth threaded portion 231.

[0094] Among them, the first threaded portion 221 on the transmission member 22 and the third threaded portion 211 on the connecting member 21 are connected by threaded matching, and the threaded matching can convert the relative rotational motion between the transmission member 22 and the connecting member 21 into translational motion. As the transmission matching amount between the first threaded portion 221 and the third threaded portion 211 increases, the connecting member 21 can achieve a rising effect relative to the transmission member 22; the second threaded portion 222 on the transmission member 22 and the fourth threaded portion 231 on the stopper 23 are connected by threaded matching, and the threaded matching can convert the relative rotational motion between the transmission member 22 and the stopper 23 into translational motion. As the transmission matching amount between the second threaded portion 222 and the fourth threaded portion 231 increases, the stopper 23 can achieve a rising effect relative to the transmission member 22.

[0095] In addition, the thread can better withstand the load force from the axial direction, and the thread matching has self-locking properties (that is, the mutually matched threads have a self-locking lead angle, and the self-locking lead angle is determined according to the static friction coefficient between the materials). For example, in the present invention, the lead angles of the first threaded portion 221 and the third threaded portion 211 are the same, and the lead angles of the first threaded portion 221 and the third threaded portion 211 are less than the self-locking lead angle determined based on the static friction coefficient, thereby preventing the connecting member 21 from rotating and falling under the action of its own gravity when it rises to the highest position, and the connecting member 21 can be effectively limited and fixed.

[0096] For another example, in the present invention, the second threaded portion 222 and the fourth threaded portion 231 have the same lead angle, and the lead angle between the second threaded portion 222 and the fourth threaded portion 231 is smaller than the self-locking lead angle determined based on the static friction coefficient, thereby preventing the transmission member 22 from rotating and falling under the action of its own gravity when it rises to the highest position, and effectively limiting and fixing the transmission member 22.

[0097] Moreover, the pitch of the first threaded portion 221 and / or the third threaded portion 211 is greater than the pitch of the second threaded portion 222 and / or the fourth threaded portion 231, so that the distance that the connecting member 21 moves relative to the transmission member 22 can be greater than the distance that the limiting member 23 moves relative to the transmission member 22, thereby ensuring that a displacement difference is formed between the connecting member 21 and the cleaning member 30, thereby achieving the effect of automatically disassembling the cleaning member 30. For example, the pitch of the first threaded portion 221 and the third threaded portion 211 is 2 times, 3 times, etc., of the pitch of the second threaded portion 222 and the fourth threaded portion 231, but is not limited thereto.

[0098] Optionally, one of the first threaded portion 221 and the third threaded portion 211 is an internal threaded structure, and the other is an external threaded structure. One of the second threaded portion 222 and the fourth threaded portion 231 is an internal threaded structure, and the other is an external threaded structure.

[0099] Alternatively, the external thread structure may adopt an intermittent multi-thread structure, which can reduce the friction resistance between the transmission member 22 and the limiting member 23 and the friction resistance between the transmission member 22 and the connecting member 21, thereby extending the service life of the disassembly mechanism 20.

[0100] In detail, in the first stroke, the first threaded portion 221 is separated from the third threaded portion 211, so that the connecting member 21 has not yet established a threaded connection relationship with the transmission member 22, that is, the connecting member 21 and the cleaning member 30 are still in a connected state; and in the second stroke, the first threaded portion 221 is matched with the third threaded portion 211, so that the distance that the connecting member 21 moves relative to the transmission member 22 is greater than the distance that the limit member 23 moves relative to the transmission member 22, thereby ensuring that a displacement difference is formed between the connecting member 21 and the cleaning member 30, thereby achieving the effect of automatically disassembling the cleaning member 30.

[0101] Furthermore, combined with Figure 2-Figure 8 , Figure 9-11 and Fig.13 As shown, a first cavity 223 is formed inside the transmission member 22, the first threaded portion 221 is arranged on the inner wall surface of the first cavity 223, and the second threaded portion 222 is arranged on the outer wall surface of the transmission member 22; the third threaded portion 211 is arranged on the outer wall surface of the connecting member 21, a second cavity 232 is formed inside the limiting member 23, and the fourth threaded portion 231 is arranged on the inner wall surface of the second cavity 232.

[0102] Among them, the first cavity 223 is provided with a first threaded portion 221 along the axial direction, and the first threaded portion 221 in the first cavity 223 is transmission-matched with the third threaded portion 211 on the outer wall of the connecting member 21; the second cavity 232 is provided with a fourth threaded portion 231 along the axial direction, and the fourth threaded portion 231 in the second cavity 232 is transmission-matched with the second threaded portion 222 on the outer wall of the transmission member 22. Such an arrangement can effectively improve the rationality of the spatial arrangement of the disassembly mechanism 20.

[0103] Specifically, combined Figure 2-Figure 8 , Figure 9-11 and Fig.13 As shown, the transmission member 22 includes a first transmission part 224 and a second transmission part 225, the first threaded part 221 is arranged on the inner wall surface of the first transmission part 224; the second transmission part 225 is connected to the outer wall surface of the first transmission part 224, the first transmission part 224 and the second transmission part 225 jointly form a first cavity 223, and the second threaded part 222 is arranged on the outer wall surface of the second transmission part 225.

[0104] Among them, the first threaded portion 221 on the first transmission portion 224 is matched with the third threaded portion 211 on the connecting member 21 for transmission, and the second threaded portion 222 on the second transmission portion 225 is matched with the fourth threaded portion 231 on the limiting member 23 for transmission. In this way, a certain displacement adjustment range can be provided for the transmission between the transmission member 22 and the connecting member 21 and the limiting member 23, thereby achieving the effect of selectively adjusting the displacement difference between the connecting member 21 and the cleaning member 30.

[0105] Furthermore, combined with Figure 2 , Figure 3 , Figure 9-11 and Fig.13 As shown, the limiting member 23 includes an outer cylinder 233 and a first limiting portion 234. A second cavity 232 is formed inside the outer cylinder 233. The first limiting portion 234 is connected to the inner side of the outer cylinder 233. The first limiting portion 234 is used to cooperate with the cleaning member 30. The inner side of the outer cylinder 233 is provided with the first limiting portion 234. The first limiting portion 234 cooperates with the cleaning member 30 in the axial direction. In this way, the relative position relationship between the limiting member 23 and the cleaning member 30 can be ensured, thereby smoothly achieving the effect of automatically disassembling the cleaning member 30.

[0106] In detail, combined Figure 2 , Figure 3 , Figure 9-11 and Fig.13 As shown, the stopper 23 also includes an inner cylinder 235, the inner cylinder 235 is connected to the inner side of the outer cylinder 233, the first stopper 234 is connected to the inner wall surface of the inner cylinder 235, and a part of the inner cylinder 235 is located in the first cavity 223. In other words, a part of the inner cylinder 235 is located in the first cavity 223 of the transmission member 22, and the outer cylinder 233 is located at the outer periphery of the second transmission part 225 of the transmission member 22, so that the second transmission part 225 can form a guiding matching relationship with the groove defined between the inner cylinder 235 and the outer cylinder 233, thereby improving the movement stability of the stopper 23 and the transmission member 22. In addition, the first stopper 234 is connected to the inner wall surface of the inner cylinder 235, so that it is more convenient for the first stopper 234 to have a limiting matching relationship with the cleaning member 30.

[0107] Optionally, a portion of the first transmission part 224 extends into the second transmission part 225, and the first transmission part 224 and the second transmission part 225 form a first guide groove 226, and a portion of the inner cylinder 235 is located in the first guide groove 226 to guide and cooperate with the first guide groove 226 in the direction extending along the rotation axis of the transmission member 22.

[0108] That is to say, in the moving direction along the connecting member 21, a portion of the first transmission part 224 extends into the second transmission part 225, so that the matching distance between the third threaded portion 211 on the connecting member 21 and the first threaded portion 221 on the inner wall of the first transmission part 224 can be increased, so that the relative movement range between the transmission member 22 and the connecting member 21 can be increased while the overall size of the transmission member 22 remains unchanged, thereby ensuring that the cleaning member 30 can be smoothly detached from the connecting member 21.

[0109] Among them, the first transmission part 224 and the second transmission part 225 form a first guide groove 226 along the direction of the connecting member 21, and a part of the inner cylinder 235 is located in the first guide groove 226, so that the limit member 23 and the transmission member 22 can utilize the guiding effect of the first guide groove 226 to move relative to each other along the specified guiding route, thereby ensuring the movement stability and accuracy of the disassembly mechanism 20.

[0110] Alternatively, combining Figure 2 , Figure 3 and Figure 7 , Figure 9-11 and Fig.13 As shown, a first guide groove 226 is formed between the first transmission part 224 and the second transmission part 225 ; a portion of the inner cylinder 235 is located in the first guide groove 226 to cooperate with the first guide groove 226 in the direction in which the rotation axis of the transmission member 22 extends.

[0111] Among them, a first guide groove 226 is formed circumferentially between the first transmission part 224 and the second transmission part 225. In the axial direction (that is, the direction extending along the rotation axis of the transmission member 22), a part of the inner cylinder 235 on the limit member 23 is guided and cooperated with the first guide groove 226, so that the limit member 23 and the transmission member 22 can move relative to each other according to the specified guide route, thereby ensuring the movement stability and accuracy of the disassembly mechanism 20.

[0112] In addition, the inner wall surface of the inner cylinder 235 is provided with a first limiting portion 234 in the circumferential direction, which can limit the movement of the cleaning member 30 and the connecting member 21 in the axial direction, thereby ensuring that the connecting member 21 will not fall off the disassembly mechanism 20, and can also ensure the effect of automatically disassembling the cleaning member 30.

[0113] Furthermore, combined with Figure 2 and Figure 3 and Fig.13 As shown, the first limiting portion 234 is constructed as an annular boss, and the annular boss is formed with a first through hole, and the connecting member 21 is penetrated by the first through hole. Among them, the inner wall surface of the inner cylinder 235 is provided with a continuous annular boss in the circumferential direction, so that the connecting member 21 located above it and the cleaning member 30 located below it can be respectively formed with an axial limiting effect, thereby preventing the cleaning member 30 from interfering with the normal disassembly action of the connecting member 21, thereby ensuring that the disassembly mechanism 20 can automatically disassemble the cleaning member 30.

[0114] In addition, a first through hole is formed inside the annular boss, and a part of the structure of the connecting member 21 passes through the first through hole, so that the connecting member 21 can be directly connected and fixed to the cleaning member 30, thereby improving the connection firmness and stability of the connecting member 21 and the cleaning member 30.

[0115] Specifically, combined Figure 2 , Figure 3 and Figure 7 , Figure 9-11 and Fig.13 As shown, one end of the second transmission part 225 facing the cleaning member 30 protrudes from one end of the first transmission part 224 facing the cleaning member 30 , and the first threaded part 221 extends to one end of the first transmission part 224 away from the cleaning member 30 .

[0116] Among them, in the axial direction, the length of one end of the second transmission part 225 toward the cleaning member 30 exceeds the length of one end of the first transmission part 224 toward the cleaning member 30. In this way, on the basis of the mutual transmission between the transmission member 22 and the limiting member 23 and the connecting member 21, the limiting member 23 and the connecting member 21 can be staggered, thereby further improving the installation and disassembly effect of the cleaning member 30.

[0117] Furthermore, combined with Figure 4-Figure 6 As shown, the connecting member 21 includes a fitting member 212 and a first magnetic adsorption member 213, the third threaded portion 211 is arranged on the outer wall surface of the fitting member 212, and the first magnetic adsorption member 213 is arranged at one end of the fitting member 212 adjacent to the cleaning member 30; a second magnetic adsorption member 31 is arranged at one end of the cleaning member 30 adjacent to the fitting member 212, and the second magnetic adsorption member 31 is magnetically adsorbed to the first magnetic adsorption member 213.

[0118] When the connecting member 21 moves downward to a position close to the cleaning member 30, the first magnetic adsorption member 213 on the connecting member 21 and the second magnetic adsorption member 31 on the cleaning member 30 can attract each other to generate magnetic attraction, thereby achieving the effect of fixing the cleaning member 30 on the disassembly mechanism 20; when the connecting member 21 moves upward and gradually moves away from the position of the cleaning member 30, the magnetic attraction between the first magnetic adsorption member 213 on the connecting member 21 and the second magnetic adsorption member 31 on the cleaning member 30 also gradually decreases until the cleaning member 30 is completely separated from the disassembly mechanism 20, so that the disassembly mechanism 20 can achieve the automatic disassembly effect of the cleaning member 30. For example, the first magnetic adsorption member 213 can be a magnet, and the second magnetic adsorption member 31 can be a metal member, but it is not limited thereto.

[0119] Specifically, combined Figure 3-Figure 6 As shown, one end of the matching member 212 adjacent to the cleaning member 30 is provided with a mounting groove 2121, and the first magnetic adsorption member 213 is provided in the mounting groove 2121. The mounting groove 2121 can provide a mounting and fixing position for the first magnetic adsorption member 213, and the mounting groove 2121 is provided at one end adjacent to the cleaning member 30, so that the distance between the first magnetic adsorption member 213 and the cleaning member 30 can be shortened, thereby enhancing the connection effect of the first magnetic adsorption member 213 on the cleaning member 30.

[0120] Furthermore, combined with Figure 3-Figure 6 As shown, the disassembly mechanism 20 also includes a first friction member 40 and a second friction member 50. The first friction member 40 is arranged on the transmission member 22. The first friction member 40 contacts the connecting member 21 and generates a first friction force that causes the connecting member 21 to rotate relative to the transmission member 22; the second friction member 50 contacts the limiting member 23 and generates a second friction force that hinders the limiting member 23 from rotating relative to the transmission member 22, thereby solving the problem of the limiting member 23 following the rotation when the transmission member 22 and the connecting member 21 are threadedly connected.

[0121] Among them, the first friction member 40 is arranged between the outer wall of the connecting member 21 and the inner wall of the limiting member 23 and forms a contact relationship with them at the same time, so that the first friction member 40 can produce a relative friction effect on the connecting member 21 and the limiting member 23, that is, the first friction member 40 produces a friction force that prevents the connecting member 21 and the limiting member 23 from moving. In this way, it can be ensured that under the premise that the connecting member 21 rotates with the mutual transmission with the transmission member 22, it can also ensure that the lifting and translation effect in the axial direction can be achieved.

[0122] In addition, the second friction member 50 is sleeved on the outer peripheral surface of the limit member 23 and forms a contact relationship therewith at the same time, so that the second friction member 50 can produce a relative friction effect on the limit member 23, that is, the second friction member 50 produces a friction force that prevents the limit member 23 from moving, so that the friction force on the limit member 23 can be increased. In this way, under the premise that the limit member 23 rotates with the mutual transmission with the transmission member 22, it can also ensure the lifting and translation effect in the axial direction. On the other hand, it can also solve the problem of the limit member 23 following the rotation when the transmission member 22 and the connecting member 21 are threadedly connected, thereby ensuring that the connecting member 21 can smoothly separate from the cleaning member 30 connected to the limit member 23.

[0123] Specifically, the transmission member 22 selectively disconnects the transmission from the connecting member 21. When the transmission member 22 moves and disconnects the transmission from the connecting member 21, the limiting member 23 and the connecting member 21 are limited and matched, and the connecting member 21 moves in the same direction and at a constant speed with the limiting member 23. Among them, as the transmission member 22 gradually rotates until the transmission is disconnected from the connecting member 21, the connecting member 21 is stopped against the inner wall surface of the limiting member 23 in the circumferential direction, and the connecting member 21 no longer transmits to each other with the transmission member 22, but forms a whole with the limiting member 23. Under the transmission action of the transmission member 22 on the limiting member 23, the limiting member 23 drives the connecting member 21 to move synchronously and at a constant speed in the same direction, so that the connecting member 21 is smoothly driven to the position for connecting and matching with the cleaning member 30, thereby improving the scientificity and rationality of the design of the disassembly mechanism 20. Moreover, the connecting member 21 and the limiting member 23 set in this way can control the lifting and lowering of the cleaning member 30, so that the cleaning member 30 can adapt to different cleaning modes and different cleaning environments.

[0124] Furthermore, combined with Figure 3-Figure 6 , Figure 9-11 and Fig.13 As shown, a third cavity 236 is formed inside the limiting member 23, a first limiting portion 234 is formed on the inner wall of the third cavity 236, part of the connecting member 21 is located in the third cavity 236, and the first limiting portion 234 cooperates with the connecting member 21 and the cleaning member 30 respectively.

[0125] Among them, a third cavity 236 is formed inside the limiting member 23 along the axial direction, and a first limiting portion 234 is formed on the inner wall surface of the third cavity 236. The first limiting portion 234 forms an axial limiting effect on the connecting member 21 and the cleaning member 30 respectively, so that the relative position relationship between the connecting member 21 and the cleaning member 30 can be guaranteed, thereby smoothly realizing the effect of automatically disassembling the cleaning member 30.

[0126] Furthermore, combined with Figure 9-11 and Fig.13 As shown, a third cavity 236 is formed inside the limiting member 23, and a first locking portion 234 is formed on the inner wall surface of the third cavity 236. Part of the connecting member 21 is located in the third cavity 236, and the first locking portion 234 is respectively limited and matched with the connecting member 21 and the cleaning member 30.

[0127] Among them, a third cavity 236 is formed inside the limiting member 23 along the axial direction, and a first clamping portion 234 is formed on the inner wall surface of the third cavity 236. The first clamping portion 234 forms an axial limiting effect on the connecting member 21 and the cleaning member 30 respectively, so that the relative position relationship between the connecting member 21 and the cleaning member 30 can be guaranteed, thereby smoothly realizing the effect of automatically disassembling the cleaning member 30.

[0128] Specifically, combined Figure 9-11As shown, the end of the connecting member 21 adjacent to the first clamping portion 234 is provided with a first abutting member 214, and the first abutting member 214 is used to abut and cooperate with the first clamping portion 234. The first abutting member 214 is circumferentially arranged on the outer peripheral surface of the end of the connecting member 21 adjacent to the first clamping portion 234, and the first abutting member 214 is located above the first clamping portion 234, which is conducive to the first abutting member 214 and the first clamping portion 234 forming an abutting and limiting relationship, thereby preventing the risk of the connecting member 21 being unexpectedly dropped off and the risk of idling between the transmission member 22 and the limiting member 23 and the connecting member 21, thereby ensuring the automatic disassembly and assembly effect of the disassembly mechanism 20 on the cleaning member 30.

[0129] Furthermore, combined with Figure 9-11 As shown, a portion of the connecting member 21 extends into the transmission member 22, and a second abutment member 24 is provided at one end of the portion of the connecting member 21 adjacent to the transmission member 22, and the second abutment member 24 is used to abut and cooperate with the transmission member 22. In the moving direction of the connecting member 21, a portion of the connecting member 21 extends into the transmission member 22, so that the connecting member 21 and the transmission member 22 can be easily established. The second abutment member 24 abuts between a portion of the connecting member 21 and the transmission member 22, thereby preventing the risk of the connecting member 21 being separated from the transmission member 22 in the process of moving away from the transmission member 22, and also limiting the maximum displacement value of the connecting member 21 relative to the transmission member 22.

[0130] In detail, combined Figure 3-Figure 6 As shown, the transmission member 22 is provided with a second limiting portion 227. At the starting position of the first stroke (that is, when the end of the connecting member 21 away from the transmission member 22 moves to the limit position farthest from the transmission member 22), the second limiting portion 227 cooperates with the connecting member 21 to prevent the connecting member 21 from falling out of the transmission member 22. In this way, it can be ensured that the third threaded portion 211 on the connecting member 21 will not fall out of the transmission member 22, thereby ensuring that the connecting member 21 can normally carry out the disassembly and assembly of the cleaning member 30.

[0131] Specifically, combined Figure 3-Figure 6 As shown, the second limiting portion 227 is constructed as an annular boss, which is formed with a second through hole, and the connecting member 21 is penetrated by the second through hole; when the end of the connecting member 21 away from the transmission member 22 moves to the extreme position farthest from the transmission member 22, the part of the connecting member 21 that is transmission-connected to the transmission member 22 cooperates with the annular boss in a limiting manner.

[0132] Among them, a continuous annular boss is arranged on the inner side of the transmission member 22 in the circumferential direction, so that an axial limiting effect can be formed on the part (that is, the third threaded portion 211) that is transmission-connected between the connecting member 21 and the transmission member 22, thereby preventing the connecting member 21 from falling off outside the transmission member 22, thereby ensuring that the connecting member 21 can be smoothly moved away from the cleaning member 30 to complete the effect of disassembling the cleaning member 30.

[0133] In addition, a second through hole is formed inside the annular boss, and part of the structure of the connecting member 21 passes through the second through hole, so that the connecting member 21 can establish a limiting relationship with the second limiting portion 227 on the transmission member 22, thereby preventing the connecting member 21 from moving downward too much and falling off the transmission member 22.

[0134] Furthermore, combined with Figure 9-12 As shown, the transmission member 22 is provided with a first threaded portion 221 and a guide portion 228, and the connecting member 21 is provided with a third threaded portion 211; wherein, when the transmission member 22 is in transmission connection with the connecting member 21, the first threaded portion 221 cooperates with the third threaded portion 211; when the transmission member 22 moves and the transmission with the connecting member 21 is disconnected, the guide portion 228 cooperates with the third threaded portion 211 to guide the third threaded portion 211 to approach the starting point of the first threaded portion 221 by limiting the circumferential rotation of the third threaded portion 211.

[0135] It can be understood that the transmission member 22 is provided with a first threaded portion 221 at the end away from the limit member 23, and a guide portion 228 is provided between the first threaded portion 221 and the end of the transmission member 22 close to the limit member 23. The first threaded portion 221 on the transmission member 22 can be threadedly matched with the third threaded portion 211 on the connecting member 21, so as to achieve the effect of converting the rotational motion between the two into relative linear motion, thereby changing the relative positions of the connecting member 21 and the transmission member 22 along the moving direction of the connecting member 21.

[0136] In addition, when the user needs to disassemble the cleaning member 30, the transmission member 22 starts to move (at this time, the transmission member 22 has not yet been threadedly engaged with the connecting member 21, and the transmission member 22 is only transmission-engaged with the limiting member 23), and the distance between the connection and the transmission member 22 changes under the restriction of the limiting member 23, and the third threaded portion 211 on the connecting member 21 is guided and engaged with the guide portion 228. The guide portion 228 can limit the third threaded portion 211 from rotating along its own circumferential direction, and as the transmission member 22 and the limiting member 23 rotate relative to each other, the guide portion 228 will gradually guide the third threaded portion 211 to approach the starting point of the first threaded portion 221, thereby ensuring that the mating end of the third threaded portion 211 close to the first threaded portion 221 remains in a fixed position in the circumferential direction, thereby facilitating the third threaded portion 211 to smoothly form a threaded mating relationship with the first threaded portion 221, thereby preventing the risk of thread mating being blocked.

[0137] Specifically, combined Figure 9-12 As shown, the guide portion 228 is formed with a plurality of guide grooves 2281 spaced apart in the circumferential direction, and the third threaded portion 211 is formed with a plurality of threads spaced apart in the circumferential direction, and the plurality of guide grooves 2281 and the plurality of threads correspond one to one.

[0138] That is to say, in the circumferential direction of the transmission member 22, the guide portion 228 is formed with a plurality of spaced guide grooves 2281, and the third threaded portion 211 is correspondingly formed with a plurality of spaced threads. In this way, without affecting the third threaded portion 211's ability to threadably cooperate with the first threaded portion 221 to change the axial relative position (that is, a thread that continues the extension trend of the original thread rather than a continuous thread can be formed on the outer periphery), a plurality of guide grooves 2281 that limit the circumferential rotation of the third threaded portion 211 can be formed in the circumferential direction, so that the third threaded portion 211 can only move along the extension direction of the guide groove 2281 under the action of the guide portion 228, and cannot rotate circumferentially, thereby ensuring that the third threaded portion 211 can smoothly threadably cooperate with the first threaded portion 221.

[0139] Furthermore, combined with Figure 9-12 As shown, the width of the guide groove 2281 decreases in the direction adjacent to the first threaded portion 221, and the width of the guide groove 2281 is larger on the side close to the connecting member 21, and is smaller on the side close to the first threaded portion 221. This makes it convenient for the first threaded portion 221 to move faster along the guide groove 2281 when it starts to move when it approaches the starting point of the third threaded portion 211 (at this time, the circumferential restriction of the guide groove 2281 relative to the first threaded portion 221 is looser). As the first threaded portion 221 gradually approaches the third threaded portion 211 (at this time, the circumferential restriction of the guide groove 2281 relative to the first threaded portion 221 is gradually tightened), the position accuracy of the mating end of the third threaded portion 211 in the circumferential direction is ensured, thereby improving the working reliability of the disassembly structure.

[0140] Specifically, combined Fig.13 and Fig.14 As shown, the disassembly mechanism 20 also includes a mounting shell 25, and the transmission member 22, the limiting member 23 and the connecting member 21 are all arranged in the mounting shell 25; wherein, the mounting shell 25 is provided with a third limiting portion 251, and the connecting member 21 is provided with a fourth limiting portion 215, and the third limiting portion 251 and the fourth limiting portion 215 are circumferentially limited.

[0141] It can be understood that the mounting shell 25 can provide a certain degree of structural protection for the transmission member 22, the limiting member 23 and the connecting member 21. The third limiting portion 251 on the mounting shell 25 and the fourth limiting portion 215 on the connecting member 21 form a circumferential limiting matching relationship. In this way, when the third threaded portion 211 on the connecting member 21 approaches the starting point of the first threaded portion 221, the connecting member 21 cannot perform circumferential rotational motion, and can only perform linear motion along the axial direction (as shown in the figure, the connecting member 21 performs vertical ascent and descent). In this way, the precise matching relationship between the third threaded portion 211 and the first threaded portion 221 can be ensured, the wear of the third threaded portion 211 can be reduced, and the service life of the transmission member 22 can be extended.

[0142] Furthermore, combined with Fig.13 and Fig.14 As shown, the third limiting portion 251 is constructed as a limiting column, and the fourth limiting portion 215 is constructed as a limiting groove. The limiting column extends into the limiting groove. The cross-section of the limiting column and the cross-section of the limiting groove are both non-circular, and the cross-section of the limiting column corresponds to the cross-section of the limiting groove.

[0143] That is to say, the third limiting portion 251 is constructed as a limiting column extending toward one side of the connecting member 21, and the limiting column can extend into the limiting groove of the connecting member 21, and the limiting column and the limiting groove form a limiting matching relationship in the circumferential direction. Among them, since the stress on the circular outer surface is uniform, it is impossible to form a relatively stable mutual limiting effect, so the cross-section of the limiting column and the cross-section of the limiting groove are both non-circular, and the cross-section of the limiting column corresponds to the cross-section of the limiting groove, so that the limiting stability between the limiting column and the limiting groove can be ensured.

[0144] Specifically, combined Fig.14 As shown, the cross-section of the limiting column and the cross-section of the limiting groove are both polygonal, which is not only convenient for processing and manufacturing, but also helps to ensure the reliability of the limiting between the two. For example, the cross-section of the limiting column and the cross-section of the limiting groove can be a regular pentagon, a regular hexagon, etc., but is not limited thereto.

[0145] Furthermore, combined with Fig.13 As shown, the power source 10 includes a driving member and a reduction mechanism, the reduction mechanism includes an input member and an output member 122 that are transmission-connected, the input member is arranged on the driving member, and the output member 122 is arranged at one end of the transmission member 22 away from the connecting member 21 .

[0146] It can be understood that the driving member can transmit the driving force to the input member, the input member is in transmission connection with the output member 122, the input member transmits the driving force to the output member 122 again, the output member 122 is connected with the transmission member 22, and the transmission member 22 then establishes a transmission relationship with the transmission member 22 and the connecting member 21, so that the automatic disassembly effect of the cleaning member 30 is finally achieved. In addition, the output member 122 is arranged at the end of the transmission member 22 away from the connecting member 21, so that the space of the transmission member 22 away from the limiting member 23 can be fully utilized, so that the structure is more compact and the space utilization rate is improved.

[0147] Specifically, combined Fig.13 As shown, the power source 10 includes a driving member and a reduction mechanism, and the reduction mechanism includes an input member and an output member 122 that are transmission-connected, the input member is arranged on the driving member, and the output member 122 is sleeved on the outer peripheral wall of the transmission member 22. In other words, the driving member can transmit the driving force to the input member, and the input member is transmission-connected with the output member 122, and the input member transmits the driving force to the output member 122 again, and the output member 122 is sleeved on the outer peripheral wall of the transmission member 22, so that the output member 122 can directly transmit the driving force to the transmission member 22 and drive the transmission member 22 to rotate synchronously, and the transmission member 22 then establishes a transmission relationship with the transmission member 22 and the connecting member 21, so that the automatic disassembly effect of the cleaning member 30 is finally achieved.

[0148] Furthermore, combined with Figure 2 , Figure 3 , Figure 9-11 and Fig.13 As shown, the transmission member 22 includes a first transmission part 224 and a second transmission part 225 , the first transmission part 224 is in transmission connection with the connecting member 21 , the output member 122 is sleeved on the first transmission part 224 , the second transmission part 225 is connected to the first transmission part 224 , and the second transmission part 225 is in transmission connection with the limiting member 23 .

[0149] It can be understood that the inner wall of the first transmission part 224 can be connected to the transmission member 22, the outer wall of the first transmission part 224 can be connected to the output member 122, and the second transmission part 225 can be connected to the limit member 23. This makes it convenient for the output member 122 to rotate by driving the first transmission part 224 while also driving the second transmission part 225 to rotate. This makes it convenient for the transmission member 22 to generate a mutual transmission relationship with the connecting member 21 and the limiting member 23 respectively through the first transmission part 224 and the second transmission part 225, and then a displacement difference is formed between the connecting member 21 and the cleaning member 30 according to the difference in mutual transmission distance, thereby achieving the effect of automatically disassembling the cleaning member 30.

[0150] In addition, the output member 122 is sleeved on the first transmission part 224 , so that while the output member 122 transmits the driving force to the first transmission part 224 , it can also save space along the axial direction of the transmission member 22 , thereby improving space utilization.

[0151] Furthermore, combined with Figure 3-Figure 6 As shown, a third cavity 236 is formed inside the limiting member 23, a first guide portion is provided on the inner wall surface of the third cavity 236, and a second guide portion 32 is provided on the cleaning member 30, and the second guide portion 32 is guided and matched with the first guide portion.

[0152] Among them, the inner wall surface of the third cavity 236 and the cleaning member 30 are respectively provided with a first guide portion and a second guide portion 32, and the first guide portion and the second guide portion 32 guide and cooperate with each other in the axial direction. This is beneficial for the cleaning member 30 to be smoothly guided into the third cavity 236, thereby improving the installation convenience of the cleaning member 30; on the other hand, it can also prevent the cleaning member 30 from unexpectedly moving in the circumferential direction in the third cavity 236, thereby improving the position stability of the cleaning member 30.

[0153] For example, the inner wall of the limiting member 23 is provided with a vertical strip-shaped protrusion, and the cleaning member 30 is provided with a groove matched with the strip-shaped protrusion, so that the connection stability between the limiting member 23 and the cleaning member 30 can be improved.

[0154] According to some optional embodiments of the present invention, combined with Figure 3-Figure 6 As shown, the cleaning member 30 includes a bracket 33 and a rag 34, the bracket 33 is connected to the connecting member 21, and the rag 34 is arranged on the bracket 33. Among them, the bracket 33 mainly plays a role of rigid support, and the bracket 33 can also play a role of installing and fixing the rag 34, thereby improving the design rationality of the cleaning member 30.

[0155] The cleaning device 100 according to the second embodiment of the utility model includes a main body 60 and a cleaning assembly 200 of the cleaning device 100 of the above embodiment, the power source 10 is arranged in the main body 60, and the cleaning member 30 is located below the main body 60. Among them, the main body 60 is the main structural member of the internal and external structure of the cleaning device 100, the power source 10 is arranged in the main body 60, and the disassembly mechanism 20 is arranged between the power source 10 and the cleaning member 30, so that the cleaning device 100 can establish a connection relationship with the cleaning member 30, so as to achieve the effect of automatically disassembling and assembling the cleaning member 30 of the cleaning device 100, thereby improving the systematization and automation effect of the cleaning device 100.

[0156] Optionally, the cleaning assembly 200 of the cleaning device 100 includes a power source 10, a cleaning member 30 and a disassembly mechanism 20, the disassembly mechanism 20 includes a connecting member 21 and a limiting member 23, the connecting member 21 and the cleaning member 30 are detachably connected, and the limiting member 23 and the cleaning member 30 are limited in cooperation; the power source 10 can drive the connecting member 21 and the limiting member 23 to move along a first direction, and the connecting member 21 and the limiting member 23 generate a displacement difference in the first direction to separate the connecting member 21 and the cleaning member 30.

[0157] The power source 10 is connected to the disassembly mechanism 20 in a transmission manner, and the power source 10 can drive the connecting member 21 and the limiting member 23 to move in a first direction (such as Figure 2 The connecting member 21 and the limiting member 23 move in the first direction (in the up and down direction, which can also be the direction of the rotation axis of the connecting member 21), and the displacement values ​​of the connecting member 21 and the limiting member 23 moving toward the first direction are different, so the connecting member 21 and the limiting member 23 have a displacement difference in the first direction (and because the cleaning member 30 cooperates with the limiting member 23 in the first direction), so that the distance between the connecting member 21 and the cleaning member 30 in the first direction gradually increases, thereby achieving the effect of automatically assembling and disassembling the connecting member 21 and the cleaning member 30.

[0158] In addition, the limiting member 23 and the cleaning member 30 are limited in the first direction, so that the movement of the cleaning member 30 in the axial direction can be limited, which is beneficial to ensure that a displacement difference is formed between the cleaning member 30 and the connecting member 21, thereby ensuring that the cleaning member 30 can be disassembled smoothly.

[0159] For example, when the cleaning member 30 establishes a connection relationship with the connecting member 21, the cleaning member 30 is connected to the connecting member 21, and the distance between the two can be 0. The two can be bonded or magnetically attracted, so that the cleaning member 30 is in a state of being installed on the cleaning device 100; when the distance between the cleaning member 30 and the connecting member 21 is far, the cleaning member 30 is in a disassembled state, and the cleaning member 30 can be automatically removed from the cleaning device 100 under the action of gravity.

[0160] Alternatively, the cleaning assembly 200 of the cleaning device 100 includes a power source 10, a cleaning member 30 and a disassembly mechanism 20, the disassembly mechanism 20 includes a connecting member 21 and a limiting member 23, the connecting member 21 and the cleaning member 30 are detachably connected, and the limiting member 23 and the cleaning member 30 are limited in cooperation; the power source 10 can drive the connecting member 21 to move in a first direction, and drive the limiting member 23 to move in a second direction, so as to separate the connecting member 21 and the cleaning member 30.

[0161] The power source 10 is connected to the disassembly mechanism 20 in a transmission manner, and the power source 10 can drive the connecting member 21 and the limiting member 23 to move in a first direction (such as Figure 2The vertical direction of the connecting member 21 may also be the direction away from the cleaning member 30 along the rotation axis of the connecting member 21) and the second direction (such as Figure 2 The connecting member 21 can be moved in the vertical direction downward, or in the direction close to the cleaning member 30 along the rotation axis of the connecting member 21. As the distance between the connecting member 21 and the limiting member 23 increases, the distance between the connecting member 21 and the cleaning member 30 also increases gradually, thereby achieving the effect of automatically assembling and disassembling the connecting member 21 and the cleaning member 30.

[0162] The state switching process of the cleaning member 30 is described in detail below:

[0163] like Figure 4 As shown, when the cleaning device 100 needs to perform mopping (for example, the sweeping robot enters the sweeping and mopping mode, the mopping mode, etc.), the second magnetic adsorption member 31 on the cleaning member 30 contacts the first magnetic adsorption member 213 on the connecting member 21, and the connecting member 21 is in the first stroke, so that the cleaning member 30 is connected to the connecting member 21. The power source 10 drives the transmission member 22 to rotate in the opposite direction, and the limiting member 23, driven by the transmission member 22, drives the cleaning member 30 to move downward together, so that the cleaning member 30 contacts the cleaning work surface and keeps rotating to perform the mopping action on the cleaning work surface.

[0164] like Figure 5 As shown, when the cleaning device 100 does not need to perform a mopping action (for example, when it detects that the cleaning working surface material is a carpet, enters the sweeping mode, or is in the recharging process), the power source 10 drives the transmission member 22 to rotate forward, and the limit member 23, driven by the transmission member 22, drives the cleaning member 30 to move upward a specified distance (the specified distance can be any value between 4mm and 10mm). The second magnetic adsorption member 31 on the cleaning member 30 and the first magnetic adsorption member 213 on the connecting member 21 always maintain contact, so that the cleaning member 30 remains connected to the cleaning device 100. In this process, the third threaded portion 211 on the connecting member 21 moves in the non-transmission area of ​​the transmission member 22, that is, the third threaded portion 211 on the connecting member 21 and the first threaded portion 221 on the transmission member 22 do not contact, and the connecting member 21 and the cleaning member 30 move synchronously.

[0165] like Figure 6As shown, when the cleaning member 30 needs to be removed from the cleaning device 100 (for example, the cleaning member 30 needs to be replaced, the cleaning member 30 needs to be self-cleaned, etc.), on the basis that the cleaning member 30 is in a raised state, the power source 10 drives the transmission member 22 to rotate forward, and the limit member 23, driven by the transmission member 22, drives the cleaning member 30 to move upward a predetermined distance (the predetermined distance can be any value between 2 mm and 5 mm). In this process, the third threaded portion 211 on the connecting member 21 moves upward to the transmission area of ​​the transmission member 22 (that is, the area where the first threaded portion 221 is provided). At this time, the connecting member 21 is in the second stroke, that is, the third threaded portion 211 on the connecting member 21 cooperates with the first threaded portion 221 on the transmission member 22. Since the pitch of the first threaded portion 221 on the transmission member 22 is greater than the pitch of the second threaded portion 222, the upper limit member 23 and the cleaning member 30 move upward in the vertical direction less than the distance of the connecting member 21 moving upward every time the transmission member 22 rotates one circle. The second magnetic adsorption member 31 on the cleaning member 30 and the first magnetic adsorption member 213 on the connecting member 21 begin to separate. When the magnetic attraction between the first magnetic adsorption member 213 and the second magnetic adsorption member 31 is less than the gravity of the cleaning member 30, the cleaning member 30 will fall off the cleaning device 100, thereby completing the disassembly of the cleaning member 30. Of course, the disassembly mechanism 20 can also drive the cleaning member 30 to move upward in the mopping state until the cleaning member 30 falls off.

[0166] Optionally, when the cleaning member 30 needs to be installed (for example, a clean cleaning member 30 needs to be replaced in the middle of mopping the floor), the cleaning device 100 can be moved to a designated position (generally a base station, where a cleaning member 30 is pre-placed). In the absence of the cleaning member 30, the cleaning member 30 is first driven down to cause the first magnetic adsorption member 213 on the connecting member 21 and the second magnetic adsorption member 31 on the cleaning member 30 to generate magnetic attraction, thereby completing the work of automatically installing the cleaning member 30.
