[0078] Next, the present application is further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment. It should be understood that the terms such as "having", "including" and "comprising" used herein do not specify the existence or addition of one or more other elements or their combinations.

[0079] Combination Figures 1 to 17 The present application relates to a cleaning device, comprising

[0080] A driving module 12, comprising a lifting driver 121;

[0081] The lifting module 14 includes a first sleeve 141 and a second sleeve 142, wherein the first sleeve 141 is connected to the power output shaft 122 of the lifting driver 121, and a spiral mechanism is formed between the first sleeve 141 and the second sleeve 142; and

[0082] A cleaning module 13, comprising a cleaning member 131, wherein the cleaning member 131 is connected to the second shaft sleeve 142;

[0083] The screw mechanism is at least driven by a first driving force of the power output shaft 122 of the lifting driver 121 to drive the cleaning member 131 to move downward relative to the lifting driver 121; and driven by a second driving force to drive the cleaning member 131 to move upward relative to the lifting driver 121.

[0084] Combine again Figures 1 to 7 , in a specific embodiment 1 of the present application:

[0085] The spiral mechanism includes: a thread groove 1421 and a rib 1411 that cooperate with each other;

[0086] The thread groove 1421 is located on the first sleeve 141 , and the rib 1411 is located on the second sleeve 142 ; or, the thread groove 1421 is located on the second sleeve 142 , and the rib 1411 is located on the first sleeve 141 ;

[0087] Wherein, the lead angles of the thread groove 1421 and the rib 1411 are smaller than the self-locking lead angle.

[0088] Further, in a preferred embodiment of the present application, the thread groove 1421 is located on the second sleeve 142 , and the rib 1411 is located on the first sleeve 141 .

[0089] In one embodiment of the present application, the rib 1411 is in the shape of an elongated strip. In another embodiment of the present application, the rib 1411 is in the shape of a spiral.

[0090] The specific shape of the rib 1411 can be selected by the staff according to the actual situation.

[0091] It is understandable that when the sweeper is operating normally, the lifting drive 121 drives the power output shaft 122 to rotate forward, thereby driving the first shaft sleeve 141 to rotate forward, and then controlling the rib 1411 on the first shaft sleeve 141 to rotate forward along the thread groove 1421 on the second shaft sleeve 142, so that a relative displacement occurs between the first shaft sleeve 141 and the second shaft sleeve 142, and the cleaning member 131 performs a downward movement relative to the lifting drive 121, and the cleaning member 131 contacts the ground to perform a cleaning operation;

[0092] When the sweeping machine senses the carpet or the sweeping machine finishes mopping, the lifting driver 121 drives the power output shaft 122 to rotate in the opposite direction, thereby controlling the ribs 1411 on the first shaft sleeve 141 to rotate in the opposite direction along the thread grooves 1421 on the second shaft sleeve 142, so that the first shaft sleeve 141 and the second shaft sleeve 142 are relatively displaced again, and the cleaning member 131 moves upward relative to the lifting driver 121 and breaks away from the ground, thereby realizing the lifting operation of the cleaning member 131;

[0093] At the same time, the self-locking lead angle is determined based on the static friction coefficient between the materials. The lead angles of the thread groove 1421 and the rib 1411 in the present application are the same, and the lead angles of the thread groove 1421 and the rib 1411 are smaller than the self-locking lead angle determined based on the static friction coefficient, so as to prevent the cleaning member 131 from rotating and falling under the action of its own gravity when it rises to the highest position, and can effectively limit and fix the cleaning member 131.

[0094] In one embodiment of the present application, during normal operation, the cleaning member 131 is in the lowest position, at which time the distance between the cleaning member 131 and the ground is H, and the distance H is 1-3 mm. When the sweeper encounters a carpet to avoid or finish work, the cleaning member 131 is in the highest position, at which time the distance between the cleaning member 131 and the ground is D, and the distance D is 5-9 mm. The lifting height of the cleaning member 131 is 4-6 mm.

[0095] In a preferred embodiment of the present application, during normal operation, the cleaning member 131 is in the lowest position, at which time the distance between the cleaning member 131 and the ground is H, and the distance H is 1.5 mm. When the sweeper encounters a carpet to avoid or finish work, the cleaning member 131 is in the highest position, at which time the distance between the cleaning member 131 and the ground is D, and the distance D is 6.5 mm. The lifting height of the cleaning member 131 is 5 mm.

[0096] The staff can adjust the lifting height of the cleaning member 131 by selecting and setting the thread groove 1421 with different numbers of circles according to the actual situation, so that the sweeping machine can be applied to different scenes and has a certain versatility.

[0097] A certain gap is arranged between each of the thread grooves 1421 and a corresponding one of the ribs 1411 , and lubricating grease is arranged in each of the thread grooves 1421 , so that the second shaft sleeve 142 can rotate smoothly.

[0098] Furthermore, the lifting module 14 also includes a sleeve cover 143 , which is located on the top of the second sleeve 142 . The bottom end of the sleeve cover 143 has a protruding first limiting portion 1431 , and the first limiting portion 1431 is located at the end of the thread groove 1421 .

[0099] In a preferred embodiment of the present application, a second limiting portion 1422 is provided at the other end of the thread groove 1421;

[0100] A first limiting surface 14111 is disposed at one side end of the rib 1411, and a second limiting surface 14112 is disposed at the other side end of the rib 1411;

[0101] When the cleaning member 131 reaches the lowest position driven by the first driving force of the power output shaft 122 of the lifting driver 121, the cleaning member 131 is limited by the cooperation between the first limiting portion 1441 and the first limiting surface 14111;

[0102] When the cleaning member 131 reaches the highest position driven by the first driving force of the power output shaft 122 of the lifting driver 121 , the cleaning member 131 is limited by the cooperation between the second limiting portion 1422 and the second limiting surface 14112 .

[0103] Further, the power output shaft 122 is fixedly connected to the first shaft sleeve 141 ; or, the power output shaft 122 is floatingly connected to the first shaft sleeve 141 .

[0104] Specifically, in a preferred embodiment of the present application, the power output shaft 122 is floatingly connected to the first shaft sleeve 141 .

[0105] Furthermore, the lifting module 14 further includes a floating assembly 144; the floating assembly 144 includes a floating sleeve 1441 and a floating element, and the floating element is at least one of a spring, a torsion spring, a spring, an elastic ball, a gas pressure support and a hydraulic support;

[0106] The floating sleeve 1441 is connected to the first sleeve 141 , and the floating sleeve 1441 is connected to the power output shaft 122 .

[0107] In one embodiment of the present application, the floating element is a spring. In another embodiment of the present application, the floating element is a torsion spring. In yet another embodiment of the present application, the floating element is a spring.

[0108] The specific arrangement of the floating element can be selected by the staff according to the actual situation.

[0109] Meanwhile, the pressure range of the floating element is 5-10N, and the floating stroke of the cleaning member 131 can be specifically set according to actual conditions.

[0110] Further, one end of the floating sleeve 1441 is fixedly connected to the power output shaft 122, and the other end is connected to the first sleeve 141;

[0111] The first sleeve 141 includes a first engaging groove 1412, and the floating sleeve 1441 is arranged in the first engaging groove 1412; the floating sleeve 1441 includes at least one first limiting protrusion 14411, and the side wall of the first engaging groove 1412 includes at least one first limiting groove 1413, and the first limiting protrusion 14411 and the first limiting groove 1413 cooperate with each other.

[0112] A first floating cavity 1442 is formed between the floating sleeve 1441 and the first sleeve 141 , and the floating element is located in the first floating cavity 1442 .

[0113] It is understandable that the floating sleeve 1441 and the first sleeve 141 are limited and fixed by the cooperation between the first limiting protrusion 14411 and the first limiting groove 1413 .

[0114] In a preferred embodiment of the present application, a guide surface 144111 is provided at the side end of the first limiting protrusion 14411, and the guide surface 144111 is a transition structure of the first limiting protrusion 14411. When the floating sleeve 1441 is installed, the guide surface 144111 can guide the first limiting protrusion 14411 to slide toward the first limiting groove 1413, so as to facilitate the floating sleeve 1441 to be sleeved in the first engaging groove 1412.

[0115] A floating element is provided between the first sleeve 141 and the floating sleeve 1441 to increase the pressure between the cleaning member 131 and the ground, thereby improving the cleaning effect of the cleaning member 131 and allowing the cleaning member 131 to float accordingly with different terrains of the ground, so that the rag on the cleaning member 131 can fit tightly to the uneven ground, allowing the sweeper to adapt to different terrains, further improving the cleaning effect, and enhancing the obstacle-crossing function of the cleaning member 131.

[0116] Furthermore, the cross section of the floating sleeve 1441 perpendicular to the axial direction is a polygon, and the first fitting groove 1412 is a polygon that matches the floating sleeve;

[0117] In a specific embodiment of the present application, the cross-section of the floating sleeve 1441 perpendicular to the axial direction is a quadrilateral, and the first fitting groove 1412 is a quadrilateral that matches the floating sleeve 1441; in another specific implementation of the present application, the cross-section of the floating sleeve 1441 perpendicular to the axial direction is a pentagon, and the first fitting groove 1412 is a pentagon that matches the floating sleeve 1441; in another specific embodiment of the present application, the cross-section of the floating sleeve 1441 perpendicular to the axial direction is a hexagon, and the first fitting groove 1412 is a hexagon that matches the floating sleeve 1441.

[0118] The specific arrangement of the cross-sections of the floating sleeve 1441 and the first engaging groove 1412 perpendicular to the axial direction can be selected by the staff according to actual conditions.

[0119] It is understandable that the polygonal floating sleeve 1441 and the first engaging groove 1412 are a limiting structure, and the cooperation between the floating sleeve 1441 and the first engaging groove 1412 is used to limit and fix the lower part of the floating sleeve 1441 relative to the first sleeve 141, so that the lower part of the floating sleeve 1441 is firmly engaged with the first sleeve 141.

[0120] In a preferred embodiment, Figure 4 As shown, the floating sleeve 1441 is connected to the first sleeve 141, and the floating sleeve 1441 is connected to the power output shaft 122 through a magnetic attraction component, and a floating cavity is formed between the bottom of the floating sleeve 1441 and the first sleeve 141 for the installation of floating components. The magnetic attraction component includes a first magnet 1444 and a fourth magnet, the first magnet 1444 is arranged on the floating sleeve 1441, and the fourth magnet is arranged on the power output shaft 122; the polarities of the ends facing each other of the first magnet 1444 and the fourth magnet are opposite; the cleaning device also includes a Hall sensor (not shown in the figure), which is fixedly arranged relative to one of the first magnet and the fourth magnet; and is used to detect whether the floating sleeve 1441 and the power output shaft 122 are installed in place.

[0121] During the installation process, the second sleeve 142, the first sleeve 141, the floating sleeve 1441, the cleaning member fixing member 1311, and the first magnet 1444 are pre-installed to form a cleaning member assembly, and then the cleaning member assembly is installed as a whole on the power output shaft 122, that is, the first magnet 1444 and the fourth magnet are magnetically fixed. When the first magnet 1444 and the fourth magnet are magnetically attracted, the Hall sensor detects the magnetic flux of the magnetic field loop formed by the magnetic attraction of the first magnet 1444 and the fourth magnet, and feeds it back to the controller. The controller compares this magnetic flux with the preset magnetic flux. If the detected magnetic flux reaches the preset magnetic flux, it indicates that the cleaning member assembly and the power output shaft 122 are installed in place. If the detected magnetic flux does not reach the preset magnetic flux, it indicates that the cleaning member assembly and the power output shaft 122 are not installed in place. That is, it is used to detect whether the cleaning member assembly is installed in place with the power output shaft 122.

[0122] Further preferably, the power output shaft 122 is made of magnetic material, the power output shaft 144 serves as the fourth magnet, and the Hall sensor is disposed above the top of the power output shaft. Preferably, the Hall sensor is disposed just above the top of the power output shaft 122 to improve detection accuracy.

[0123] Preferably, a clearance hole is provided on the floating sleeve 1441 to make the magnetic attraction between the first magnet and the fourth magnet or the power output shaft more secure.

[0124] As a deformation, such as Fig.10 As shown, the second sleeve 142 can be integrally formed on the cleaning member fixing member 1311, further facilitating the pre-installation of the cleaning member assembly. Figure 4 As shown, the second sleeve 142 is detachably connected to the cleaning member fixing member 1311, for example, by snap-fitting or threading.

[0125] In a preferred embodiment of the present application, the floating sleeve 1441 further includes a third fitting groove 14414 , and the other end of the power output shaft 122 is disposed in the third fitting groove 14414 and connected to the floating sleeve 1441 .

[0126] Specifically, the power output shaft 122 is snap-connected to the third fitting groove 14414 , or the power output shaft 122 is magnetically connected to the third fitting groove 14414 via a first magnet 1444 .

[0127] In a preferred embodiment of the present application, the power output shaft 122 and the third engaging groove 14414 are magnetically connected via a first magnet 1444 .

[0128] The first magnet 1444 may be arranged at the bottom of the third fitting groove 14414 , or the first magnet 1444 may be arranged at a circumferential region inside the third fitting groove 14414 .

[0129] The staff can make specific selections for the specific setting of the position of the first magnet 1444 according to actual conditions.

[0130] The cross section of the power output shaft 122 perpendicular to the axial direction is a polygon, and the third engaging groove 14414 is a polygon that matches the power output shaft 122 .

[0131] In a specific embodiment of the present application, the cross-section of the power output shaft 122 perpendicular to the axial direction is a quadrilateral, and the third fitting groove 14414 is a quadrilateral that matches the power output shaft 122; in another specific implementation of the present application, the cross-section of the power output shaft 122 perpendicular to the axial direction is a pentagon, and the third fitting groove 14414 is a pentagon that matches the power output shaft 122; in another specific embodiment of the present application, the cross-section of the power output shaft 122 perpendicular to the axial direction is a hexagon, and the third fitting groove 14414 is a hexagon that matches the power output shaft 122.

[0132] The specific arrangement of the cross-section of the power output shaft 122 and the third engaging groove 14414 perpendicular to the axial direction can be selected by the staff according to actual conditions.

[0133] It can be understood that the polygonal third engaging groove 14414 and the power output shaft 122 form a limiting structure, and the cooperation between the third engaging groove 14414 and the power output shaft 122 is used to initially limit and fix the power output shaft 122 of the lifting drive 121 and the floating sleeve 1441; at the same time, a first magnet 1444 is arranged inside the third engaging groove 14414, and the power output shaft 122 and the floating sleeve 1441 are further limited and fixed by the first magnet 1444, so that the power output shaft 122 and the floating sleeve 1441 are firmly engaged, and it is convenient to disassemble and separate the power output shaft 122 and the floating sleeve 1441, and finally it is convenient to disassemble the cleaning part 131.

[0134] Furthermore, the staff controls the starting positions of different cleaning members 131 by controlling the assembly directions of the power output shaft 122 and the floating sleeve 1441 , and the floating sleeve 1441 and the first sleeve 141 .

[0135] Furthermore, the rotation speed of the power output shaft 122 of the lifting driver 121 is different, and the magnetic force of the first magnet 1444 is different.

[0136] When the rotation speed of the power output shaft 122 of the lifting drive 121 is high, the first magnet 1444 with a larger magnetic force can be selected; when the rotation speed of the power output shaft 122 of the lifting drive 121 is low, the first magnet 1444 with a smaller magnetic force can be selected. According to the rotation speed of the power output shaft 122 of the lifting drive 121, the first magnet 1444 with a specific magnetic force is selected to ensure that the floating sleeve 1441 is stably connected to the power output shaft 122 of the lifting drive 121.

[0137] Furthermore, the second shaft sleeve 142 is fixedly connected to the cleaning member 131 , or the second shaft sleeve 142 and the cleaning member 131 are integrally formed.

[0138] The specific setting of the connection method between the second sleeve 142 and the cleaning member 131 can be selected by the staff according to the actual situation.

[0139] Furthermore, the lifting module 14 further includes a damping member 146 , and the driving module further includes a housing 123 . The damping member 146 is disposed between the second shaft sleeve 142 and the housing 123 .

[0140] In a preferred embodiment of the present application, the damping member 146 is made of a flexible material.

[0141] It is understandable that the present application arranges a damping member 146 between the second sleeve 142 and the outer shell 123 to avoid friction between the second sleeve 142 and the outer shell 123, thereby increasing the service life of the second sleeve 142. At the same time, the damping member 146 is made of a flexible material, resulting in friction between the damping member 146 and the outer shell 123, which hinders the second sleeve 142 from reaching the same rotation speed as the first sleeve 141, thereby extending the time for the second sleeve 142 and the first sleeve 141 to reach the same rotation speed, so that no matter how the rotation speed of the power output shaft 122 of the lifting drive 121 is set, as long as the power output shaft 122 rotates normally, it can rotate relative to the second sleeve 142, and the cleaning member 131 can rise or fall under the action of the spiral mechanism.

[0142] Furthermore, it also includes: a sensor and a controller, and the controller is electrically or wirelessly connected to the lifting driver 121 and the sensor respectively.

[0143] It is understandable that the sensor is used to sense and identify the carpet. When the sensor senses the presence of the carpet, the sensor sends a feedback signal to the controller. After receiving the feedback signal, the controller sends a control instruction to the lifting drive 12 according to the feedback result. The first driving force of the power output shaft 122 of the lifting drive 121 drives the cleaning element 131 to perform an upward movement relative to the lifting drive 121, thereby realizing the lifting function of the cleaning element 131, and then performing an avoidance operation on the carpet.

[0144] In summary, before the sweeper starts working, the cleaning member 131 is at the highest position. When the sweeper starts working, the controller sends a control instruction to the lifting drive 121 to control the power output shaft 122 of the lifting drive 121 to start forward rotation, thereby driving the first shaft sleeve 141 to rotate forward, thereby controlling the rib 1411 on the first shaft sleeve 141 to rotate in the opposite direction along the thread groove 1421 on the second shaft sleeve 142. At the same time, under the action of the damping member 146, a relative displacement occurs between the first shaft sleeve 141 and the second shaft sleeve 142, and the cleaning member 131 moves downward relative to the lifting drive 121, and the cleaning member 131 contacts the ground to perform a cleaning operation.

[0145] When the sensor senses the presence of the carpet, the sensor sends a feedback signal of sensing the carpet to the controller. After receiving the feedback signal, the controller sends a control instruction to the lifting driver 121 according to the feedback result, so as to control the power output shaft 122 of the lifting driver 121 to start reverse rotation, thereby controlling the rib 1411 on the first shaft sleeve 141 to rotate in the opposite direction along the thread groove 1421 on the second shaft sleeve 142. At the same time, under the action of the damping member 146, the first shaft sleeve 141 and the second shaft sleeve 142 are relatively displaced again, and the cleaning member 131 moves upward relative to the lifting driver 121 and breaks contact with the ground, thereby realizing the lifting operation of the cleaning member 131 to avoid the carpet.

[0146] When the sweeper finishes working, the controller sends a control instruction to the lifting drive 121 to control the power output shaft 122 of the lifting drive 121 to start reverse rotation, thereby driving the first shaft sleeve 141 to rotate reversely, and then controlling the ribs 1411 on the first shaft sleeve 141 to rotate reversely along the threaded groove 1421 on the second shaft sleeve 142. At the same time, under the action of the damping member 146, the first shaft sleeve 141 and the second shaft sleeve 142 are displaced relative to each other again, and the cleaning member 131 moves upward relative to the lifting drive 121 and breaks contact with the ground, thereby realizing the lifting operation of the cleaning member 131 and preventing the cleaning member 131 from causing secondary pollution to the cleaned ground.

[0147] Combine again Figures 8-10 , in a specific embodiment 2 of the present application:

[0148] A solution further formed on the basis of the specific embodiment 1;

[0149] An elastic element 145 is arranged between the first sleeve 141 and the second sleeve 142, and the elastic element 145 is at least one of a tension spring, an elastic rope, a torsion spring and a spring sheet;

[0150] The elastic element 145 provides the second driving force.

[0151] In one embodiment of the present application, the elastic element 145 is a tension spring. In another embodiment of the present application, the elastic element 145 is a torsion spring. In another embodiment of the present application, the elastic element 145 is a spring.

[0152] The specific configuration of the elastic element 145 can be selected by the staff according to the actual situation.

[0153] In a preferred embodiment of the present application, the cleaning member 131 further includes a second connecting portion 1312 , the first sleeve 141 further includes a first connecting portion 1414 , and the first and second ends of the elastic element 145 are respectively connected to the first connecting portion 1414 and the second connecting portion 1312 .

[0154] It is understandable that when the sweeper is operating normally, the controller sends a control instruction to the lifting driver 121, and the lifting driver 121 drives the power output shaft 122 to rotate according to the control instruction, thereby driving the first shaft sleeve 141 to rotate, and then controlling the rib 1411 on the first shaft sleeve 141 to rotate along the thread groove 1421, and at the same time, under the action of the damping member 146, a relative displacement occurs between the first shaft sleeve 141 and the second shaft sleeve 142, and the cleaning member 131 descends in the vertical direction, and the rag on the cleaning member 131 contacts the ground to perform a mopping operation, and at the same time, the elastic element 145 is in a stretched state;

[0155] When the sensor senses the presence of the carpet, the sensor sends a feedback signal to the controller. After receiving the feedback signal, the controller sends a control instruction to the lifting driver 121 according to the feedback result, so as to control the lifting driver 121 to stop working, thereby stopping the stretching operation of the elastic element 145. Under the action of the second driving force of the elastic element 145, the rib 1411 rotates along the thread groove 1421 again. At the same time, under the action of the damping member 146, the first shaft sleeve 141 and the second shaft sleeve 142 are relatively displaced again, and the cleaning member 131 rises in the vertical direction and breaks away from the ground, thereby realizing the lifting function of the rag on the cleaning member 131, and then performing the carpet avoidance operation.

[0156] Alternatively, when the sweeper finishes working, the controller sends a control instruction to the lifting drive 121 to control the lifting drive 121 to stop working, thereby stopping the stretching operation of the elastic element 145, and under the action of the second driving force of the elastic element 145, the rib 1411 rotates along the thread groove 1421 again. At the same time, under the action of the damping member 146, the first sleeve 141 and the second sleeve 142 are relatively displaced again, and the cleaning member 131 rises in the vertical direction and breaks away from contact with the ground, thereby realizing the lifting function of the rag on the cleaning member 131 to prevent the cleaning member 131 from causing secondary pollution to the cleaned ground.

[0157] Recombination Figures 11 to 27 , in a specific embodiment 3 of the present application:

[0158] A solution further formed on the basis of the specific embodiment 1;

[0159] The floating sleeve 1441 is connected to the second sleeve 142 , and the floating sleeve 1441 is connected to the cleaning member 131 .

[0160] Further, one end of the floating sleeve 1441 is fixedly connected to the second sleeve 142, and the other end is connected to the cleaning member 131;

[0161] The cleaning member 131 includes a cleaning member fixing member 1311, the floating sleeve 1441 includes a second fitting groove 14412, and the cleaning member fixing member 1311 is arranged in the second fitting groove 14412; the cleaning member fixing member 1311 includes at least one second limiting protrusion 13111, and the floating sleeve 1441 includes at least one second limiting groove 14413, and the second limiting protrusion 13111 and the second limiting groove 14413 are matched;

[0162] A second floating cavity 1443 is formed between the floating sleeve 1441 and the cleaning member fixing member 1311 , and the floating element is located in the second floating cavity 1443 .

[0163] It is understandable that the floating sleeve 1441 and the cleaning member 131 are limited and fixed by the cooperation between the second limiting protrusion 13111 and the second limiting groove 14413 .

[0164] A floating element is provided between the floating sleeve 1441 and the cleaning member 131 to increase the pressure between the cleaning member 131 and the ground, thereby improving the cleaning effect of the cleaning member 131 and allowing the cleaning member 131 to float accordingly with different terrains of the ground, so that the rag on the cleaning member 131 can fit tightly against the uneven ground, allowing the sweeper to adapt to different terrains, further improving the cleaning effect, and enhancing the obstacle-crossing function of the cleaning member 131.

[0165] Furthermore, the cross-sectional area of ​​the cleaning member fixing member 1311 perpendicular to the axial direction is a polygon, and the second engaging groove 14412 is a polygon that matches the cleaning member fixing member 1311 .

[0166] In a specific embodiment of the present application, the cross-section of the cleaning member fixing member 1311 perpendicular to the axial direction is a quadrilateral, and the second fitting groove 14412 is a quadrilateral that matches the cleaning member fixing member 1311; in another specific implementation of the present application, the cross-section of the cleaning member fixing member 1311 perpendicular to the axial direction is a pentagon, and the second fitting groove 14412 is a pentagon that matches the cleaning member fixing member 1311; in another specific embodiment of the present application, the cross-section of the cleaning member fixing member 1311 perpendicular to the axial direction is a hexagon, and the second fitting groove 14412 is a hexagon that matches the cleaning member fixing member 1311.

[0167] It is understandable that the polygonal second engaging groove 14412 and the cleaning member fixing member 1311 are a limiting structure, and the cooperation between the second engaging groove 14412 and the cleaning member fixing member 1311 is used to limit and fix the cleaning member 131 and the floating sleeve 1441 .

[0168] In a preferred embodiment of the present application, the floating sleeve 144 includes a fixing portion 14415, the second sleeve 142 includes a fourth fitting groove 1423, and the fixing portion 14415 is disposed in the fourth fitting groove 1423.

[0169] The cross-sectional area of ​​the fixing portion 14415 perpendicular to the axial direction is a polygon, and the fourth engaging groove 1423 is a polygon matched with the fixing portion 14415 .

[0170] In a specific embodiment of the present application, the cross-section of the fixing portion 14415 perpendicular to the axial direction is a quadrilateral, and the fourth fitting groove 1423 is a quadrilateral that matches the fixing portion 14415; in another specific implementation of the present application, the cross-section of the fixing portion 14415 perpendicular to the axial direction is a pentagon, and the fourth fitting groove 1423 is a pentagon that matches the fixing portion 14415; in another specific embodiment of the present application, the cross-section of the fixing portion 14415 perpendicular to the axial direction is a hexagon, and the fourth fitting groove 1423 is a hexagon that matches the fixing portion 14415.

[0171] It is understandable that the polygonal fourth engaging groove 1423 and the fixing portion 14415 are a limiting structure, and the cooperation between the fourth engaging groove 1423 and the fixing portion 14415 is used to initially limit and fix the second sleeve 142 and the floating sleeve 1441 .

[0172] Furthermore, the second sleeve 142 and the floating sleeve 1441 are connected by a snap-fit ​​connection; or, the second sleeve 142 and the floating sleeve 1441 are connected by a magnetic attraction connection.

[0173] Specifically, in a preferred embodiment of the present application, the second sleeve 142 and the floating sleeve 1441 are connected by magnetic attraction.

[0174] A second magnet 1445 is arranged on the floating sleeve 1441, and the second sleeve 142 and the floating sleeve 1441 are further limited and fixed by the second magnet 1445, so that the second sleeve 142 and the floating sleeve 1441 are firmly embedded, and the second sleeve 142 and the floating sleeve 1441 are easy to disassemble and separate, and finally the cleaning member 131 is easy to disassemble.

[0175] In a preferred embodiment of the present application, Fig.23 As shown, one end of the floating sleeve 1441 is magnetically connected to the second sleeve 142 through a magnetic component, and the other end is connected to the cleaning member fixing member 1311 for installing the cleaning member, and a second floating cavity is formed between the two, and the floating element is located in the second floating cavity.

[0176] Optional bottom, the magnetic assembly includes a second magnet 1445 and a third magnet 151 respectively arranged on the floating sleeve 1441 and the second sleeve 142, the second magnet 1445 and the third magnet 151 have opposite polarities at the ends facing each other, and the floating sleeve 1441 and the second sleeve 142 are detachably fixedly connected through the mutual attraction between the second magnet 1445 and the third magnet 151.

[0177] Furthermore, the cleaning device also includes a Hall sensor (not shown in the figure), which is fixedly arranged relative to one of the second magnet and the third magnet; it is used to detect whether the floating sleeve 1441 and the second sleeve 142 are installed in place. In actual use, the floating sleeve 1441 and the cleaning member fixing member 1311 and the second magnet 1445 are pre-installed to form a combination, and then the second magnet 1445 and the third magnet 151 at the top of the entire combination are fixedly connected. At this time, the Hall sensor detects the magnetic flux of the magnetic field loop formed by the magnetic attraction of the second magnet and the third magnet, and feeds it back to the controller. The controller compares this magnetic flux with the preset magnetic flux. If the detected magnetic flux reaches the preset magnetic flux, it indicates that the combination and the second sleeve are installed in place. If the detected magnetic flux does not reach the preset magnetic flux, it indicates that the combination and the second sleeve are not installed in place.

[0178] Alternatively, if Fig.23 and Fig.24As shown, the second sleeve 142 is provided with a first groove area, i.e., the fourth engaging groove 1423, on the side facing the cleaning member fixing member 1311, and an annular second groove area 1425 is provided on the side facing away from the cleaning member fixing member 1311; the thread groove 1421 or the rib 1411 is provided in the second groove area 1425, the top of the first sleeve 141 is connected to the power output shaft 122, and the bottom of the first sleeve 141 is embedded in the second groove area 1425. Preferably, the cross section of the first sleeve is an inverted U-shape.

[0179] The third magnet 151 is arranged on the bottom of the first groove area; at least the second magnet 1445 extends into the first groove area and is magnetically fixed to the third magnet 1425, so that the entire second sleeve 142 and the first sleeve 141 and the power output shaft 122 have a compact structure.

[0180] Optionally, the Hall sensor can be arranged in the first groove area, and the Hall sensor is closer to the groove bottom of the first groove area than the third magnet 151, that is, the Hall sensor is arranged at the groove bottom of the first groove area. As a variation, the Hall sensor can also be arranged on the floating sleeve 1441, and the second magnet 1445 is closer to the groove bottom of the first groove area than the Hall sensor.

[0181] Optionally, the Hall sensor is disposed on the top of the power output shaft 122, the power output shaft 122 is made of a magnetic conductive material, and the end of the power output shaft 122 is close to and directly opposite to the third magnet 151. Alternatively, the power output shaft 122 is made of a magnetic conductive material and directly serves as the third magnet, and there is no need to provide the third magnet 151 in the first groove area. At this time, preferably, the bottom of the first groove area is provided with an opening or a clearance hole to facilitate the magnetic attraction and fixation of the third magnet and the second magnet.

[0182] like Fig.25 and Fig.26 As shown, there are at least two second magnets 1445, and correspondingly, there are at least two third magnets 151; wherein, the bottom edge of the floating sleeve 1441 is provided with an outer edge 1446 protruding and extending outward, and the outer edge 1446 is relatively distributed with the bottom of the second groove area 1425; at least one of the third magnets 151 is arranged on the bottom of the second groove area 1425, and at least one of the second magnets 1445 is arranged on the outer edge 1446, and the second magnet 1445 is magnetically connected to the third magnet 151, thereby further increasing the connection firmness between the second sleeve 142 and the floating sleeve 1441.

[0183] like Fig.26 As shown, preferably, an annular flange 1448 is provided on the edge of the outer edge, and correspondingly, as shown in FIG. Fig. 27As shown, an extension portion 1426 is provided at the bottom of the second sleeve 142, and the extension portion 1426 abuts against the outer edge so that an annular groove is formed between the annular flange, the outer edge, and the outer wall of the extension portion 1426, and the second magnet 1445 is annular and is disposed in the annular groove.

[0184] like Fig. 27 As shown, an annular hole 1427 is provided on the second groove area of ​​the second sleeve 142, and the third magnet 151 is embedded in the annular hole 1427, so that the third magnet and the second magnet are relatively distributed.

[0185] As a variation, the annular flange and the extension portion may not be provided, and the third magnet and the second magnet may be directly provided on the bottom of the second sleeve and the top of the floating sleeve respectively.

[0186] Optionally, the cleaning member fixing member 1311 and the floating sleeve are connected by snap-fit, specifically, as Fig.25 and Fig.26 As shown, at least one matching hole 1447 is provided on the side wall of the floating sleeve 1441, the top of the cleaning member fixing member 1311 extends into the bottom inner cavity of the floating sleeve, and a buckle is provided on the top or side wall of the cleaning member fixing member 1311, and the buckle is hooked on the matching hole 1447 to achieve a detachable connection between the two. The positions of the buckle and the matching hole can be swapped, or other methods can be used for fixed connection, such as magnetic attraction. Or, as Fig.23 As shown, the floating sleeve 1441 is molded on the cleaning element fixing element 1311 .

[0187] Furthermore, the lifting module 14 further includes a damping member 146 , and the driving module further includes a housing 123 . The damping member 146 is disposed between the second shaft sleeve 142 and the housing 123 .

[0188] In a preferred embodiment of the present application, the damping member 146 is an O-ring, a sealing ring fixing groove 1424 is arranged on the second sleeve 142 , and the damping member 146 is arranged in the sealing ring fixing groove 1424 .

[0189] It can be understood that, in the present application, an O-ring is arranged between the second sleeve 142 and the outer shell 123, and friction exists between the O-ring and the outer shell 123, which hinders the second sleeve 142 from reaching the same rotation speed as the first sleeve 141, thereby extending the time for the second sleeve 142 to reach the same rotation speed as the first sleeve 141, so that no matter how the rotation speed of the power output shaft 122 of the lifting drive 121 is set, as long as the power output shaft 122 rotates normally, it can rotate relative to the second sleeve 142, and the cleaning member 131 can rise or fall under the action of the spiral mechanism.

[0190] Another embodiment, such as Fig.18 and Fig.19 As shown, the drive module also includes a shell 123, and the shell 123 is sleeved on the outside of the second sleeve 143. The shell 123 is provided with at least one clearance hole 1231, and the clearance hole 1231 is provided with at least one deformation part 1232. The deformation part has at least one protrusion protruding inwardly, and the shell 123 maintains interference fit with the outer wall surface of the second sleeve through the protrusion. Since the deformation part has a deformation space in the clearance hole, an elastic interference fit is formed between the protrusion and the outer wall of the second sleeve, ensuring that the protrusion always maintains a certain friction with the outer wall of the second sleeve to play a damping role.

[0191] Optionally, the shell and the deformation portion 1232 are integrally formed and made of plastic material, for example, the plastic may be POM, PP plastic, etc.

[0192] like Fig.19 As shown, the number of the clearance holes 1231 on the housing can be one, two, or more. When the number of the clearance holes 1231 is multiple, it is best that the multiple clearance holes 1231 are evenly distributed on a circle of the outer wall of the housing 123. The number of the deformation parts 1232 provided in each clearance hole 1231 can be one, two, or more, and at least one protrusion is provided on the deformation part 1232. For example, the deformation part 1232 can be in a wave shape, and the crest position of the wave shape is a protrusion. By providing multiple protrusions, the protrusions serve as damping members, and the damping effect of the housing and the second sleeve is further enhanced.

[0193] As a deformation, the deformation portion may be in other shapes besides the wave shape, such as M-shape, V-shape, or other arc shapes or curved surfaces.

[0194] like Fig.19 As shown, for the shell, a plurality of spaced-apart hanging ears 1233 are also provided on the top of the shell 123, and the shell is detachably connected to the chassis 11 of the sweeper or cleaning equipment through the hanging ears 1233, and the hanging ears can be connected to the chassis 11 by snap-fit, magnetic attraction, or other detachable connection methods.

[0195] In another embodiment, if Fig. 20 and Fig.21 As shown, it also includes: a sensor and a controller, and the controller is electrically or wirelessly connected to the lifting driver 121 and the sensor respectively.

[0196] In a preferred embodiment, the drive module further includes a housing 123, and the housing 123 is sleeved outside the outer wall of the second sleeve 142; the sensor includes a light emitter 1471 and a light receiver 1472 which are relatively arranged on the housing 123, and a light path area is formed between the light emitter 1471 and the light receiver 1472; when the second sleeve 142 is driven by the lifting driver 121 and reaches the highest point of the rising position, at least part of the second sleeve 142 is located in the light path area, blocking the light emitted by the light emitter 1471, and the light receiver 1472 cannot receive the light. The light emitted by the transmitter 1471, at this time, the sensor feeds back to the controller a signal that the second sleeve 142 has risen to the position, that is, a signal that the cleaning part has risen to the position, and the controller outputs a control signal based on this signal to control the lifting drive to stop moving; on the contrary, when the second sleeve 142 has not reached the highest rising position, the light emitted by the light transmitter 1471 is always received by the light receiver 1472. At this time, the sensor feeds back to the controller that the height of the second sleeve has not been reached, and the lifting drive continues to run or starts moving, so as to know the position of the second sleeve and the cleaning part.

[0197] Preferably, in another embodiment, Fig. 20 , Fig.21 and Fig. 22 As shown, the driving module also includes a housing 123, a light blocking member 148 and a biasing member 149, and the housing is sleeved on the outer wall of the second sleeve 142; the sensor includes a light emitter 1471 and a light receiver 1472 arranged on the housing relatively to each other, and a light path area is formed between the light emitter 1471 and the light receiver 1472; the light blocking member 148 is arranged on the housing 123 in a liftable manner; the biasing member 149 is arranged on the housing 123, and applies a biasing force to the light blocking member 148, driving the bottom of the light blocking member 148 to be located directly below the light path area; when the second sleeve 142 is driven by the lifting driver 122 to reach the highest point of the rising position, the second sleeve 142 The top pushes the light blocking member 148 to do an upward movement to extend into the light path area to block the light emitted by the light emitter 1471, and the light receiver 1472 cannot receive the light emitted by the light emitter 1471. At this time, the sensor feeds back a signal to the controller that the second sleeve 142 has risen to the position, that is, a signal that the cleaning member has risen to the position. Based on this signal, the controller outputs a control signal to control the lifting drive to stop moving; on the contrary, when the second sleeve 142 has not reached the highest rising position, the light emitted by the light emitter 1471 is always received by the light receiver 1472. At this time, the sensor feeds back to the controller that the height of the second sleeve has not been reached, and the lifting drive continues to run or starts to run.

[0198] Preferably, if Fig. 22As shown, the light shielding member 148 includes a mounting portion 1481, a light shielding portion 1483 and a boss 1482 arranged side by side on a side wall of the mounting portion 1481, one end of the biasing member 149 is arranged on the housing 123, and the other end is arranged on the boss 1482; the mounting portion 1481 is pushed by the second sleeve 142 to drive the light shielding portion 1483 to extend into the light path area. For the biasing member, the biasing member is preferably a compression spring, and the biasing member and the light shielding portion are arranged side by side, so that the biasing member will not be located in the light path area and will not interfere with the transmission of light in the light path area.

[0199] The above-mentioned sensor may be an optical coupling sensor, a through-beam sensor, or any other form of sensor.

[0200] Preferably, if Fig. 22 As shown, the driving module also includes a cover body 150, which is fixedly connected to the chassis 11 (mentioned below), and the housing 123 is connected to the chassis 11, so that the top of the above-mentioned biasing member is arranged on the bottom of the cover body 150, and the light emitter and the light receiver are arranged on the cover body through the fixing seat 1473, and the light emitter 1471 and the light receiver 1472 are relatively distributed on the two side walls of the U-shape.
