[0020] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0021] After long-term research, the inventors found that in order to facilitate cleaning activities, the cleaning mechanism is often fixed at a lower position of the cleaning device. However, in some cleaning scenarios, the cleaning mechanism needs to be in a higher position. For example, if the cleaning mechanism is a wet mop, when the cleaning device passes through a silk fabric area such as a carpet, the cleaning mechanism is in a lower position, which may damage the silk fabric such as the carpet. In the prior art, the cleaning action of the cleaning device is relatively simple, and the height of the cleaning mechanism is not convenient to adjust. In order to solve this technical problem, the present application provides the following embodiments.

[0022] The cleaning device may have one or more functions of sweeping, washing, mopping, and vacuuming. For example, the cleaning device may be a sweeping robot, a mopping robot, a washing and mopping robot, a sweeping, washing and mopping robot, a vacuum cleaner, etc. The following is an exemplary structure of the cleaning device described in the embodiment of the cleaning device of the present application.

[0023] like Figure 1 As shown, the cleaning device 1 described in the embodiment of the cleaning device of the present application includes a device body 10 and a cleaning component 20. The cleaning component 20 is connected to the bottom of the device body 10. Figures 2 to 4As shown, the cleaning assembly 20 includes a cleaning mechanism 100, a transmission mechanism 200 and a drive motor assembly 300. The transmission mechanism 200 includes a first transmission member 210, a second transmission member 220 and a one-way stopper 230. Among them, the first transmission member 210 is connected to the drive motor assembly 300 and the cleaning mechanism 100 respectively, and the first transmission member 210 rotates with the drive motor assembly 300 and can move along a preset axis direction to approach or move away from the drive motor assembly 300. The second transmission member 220 is connected to the first transmission member 210 and the one-way stopper 230 respectively, and the one-way stopper 230 is configured to allow the second transmission member 220 to rotate along a preset first direction α and limit the second transmission member 220 to rotate along a preset second direction β opposite to the preset first direction α. ​​The first transmission member 210 and the second transmission member 220 are threadedly connected. The drive motor assembly 300 drives the cleaning mechanism 100 to rise and fall between the second position and the first position relative to the device body 10 along the preset axis direction through the first transmission member 210 and the second transmission member 220. The first transmission member 210 can move along a preset axis direction to approach or move away from the driving motor assembly 300 by rotating with the driving motor assembly 300. The one-way stopper 230 is used to control the second transmission member 220 to rotate along a preset first direction α.

[0024] The cleaning component 20 can clean the area below the cleaning device 1 .

[0025] Alternatively, if Figure 5 As shown, the cleaning device 1 may include a moving component 11, a detection component (not marked) and a processor (not shown). The device body 10 may support and connect the moving component 11, the detection component and the processor. The detection component may include a cliff sensor 12 for detecting the cliff terrain. Driven by the moving component 11, the cleaning device 1 may move on the surface to be cleaned (e.g., the ground). Through the detection component, the cleaning device 1 may detect various areas of the surface to be cleaned and send the detected information to the processor. The processor may analyze the detected information to determine the properties of each area of ​​the surface to be cleaned, and adjust the cleaning working mode according to the properties of each area.

[0026] For example, the detection component may include an ultrasonic sensor and a camera. When the cleaning device 1 is moved in the scene to be cleaned, driven by the moving component 11, when the ultrasonic sensor of the detection component detects that there is a silk fabric area such as a carpet in front of the moving direction, the cleaning device 1 can adjust the cleaning method when passing through the silk fabric area such as the carpet, so that the cleaning process does not damage the silk fabric such as the carpet. For another example, when the cleaning device 1 is moving in the surface to be cleaned, when the camera of the detection component detects that there is a short step in the area in front of the moving direction, the cleaning device 1 can adjust the contact method with the area when climbing the short step to reduce the obstruction of the short step to the movement of the cleaning device 1.

[0027] like Figure 6 As shown, the cleaning assembly 20 can have an ascending state and a descending state. The cleaning assembly 20 can be used to clean the surface to be cleaned. During the cleaning process, the cleaning assembly 20 can be in a descending state, so that the cleaning assembly 20 can contact the surface to be cleaned and then apply pressure, and move relative to the surface to be cleaned to achieve cleaning of the surface to be cleaned.

[0028] When no cleaning is performed, the cleaning component 20 may be in an ascending state. For example, if the cleaning component 20 is a wet mop, when the cleaning device 1 passes through a silk fabric area such as a carpet, the cleaning component 20 is in an ascending state to avoid damaging the silk fabric such as the carpet. For another example, when the cleaning device 1 climbs a short step, the cleaning component 20 is in an ascending state to reduce the obstruction of the short step to the movement of the cleaning device 1.

[0029] like Figures 2 to 4 As shown, the transmission mechanism 200 can be connected to the cleaning mechanism 100. The driving motor assembly 300 is connected to the cleaning mechanism 100 through the transmission mechanism 200. The driving motor assembly 300 is used to drive the transmission mechanism 200 to move, so as to drive the cleaning mechanism 100 to rotate relative to the device body 10. The driving motor assembly 300 is also used to drive the transmission mechanism 200 to move, so as to drive the cleaning mechanism 100 to rise and fall between the first position and the second position along the preset axis direction relative to the device body 10. The preset axis can be the rotation axis of the cleaning mechanism 100, and the preset axis direction can be the extension direction of the rotation axis of the cleaning mechanism 100.

[0030] The cleaning mechanism 100 can be used to perform cleaning work. The cleaning mechanism 100 can contact with the surface to be cleaned and rotate relative to the surface to be cleaned to clean the surface to be cleaned. The cleaning mechanism 100 rotates relative to the device body 10 to achieve rotation relative to the surface to be cleaned.

[0031] Alternatively, if Figure 2 As shown, the cleaning mechanism 100 may include a cleaning member 101 and a connecting seat 102, wherein the cleaning member 101 is connected to one side of the connecting seat 102. Specifically, the material of the cleaning member 101 may include a soft material that can absorb water, and during the cleaning process, the cleaning member 101 is wetted and then contacts the surface to be cleaned, and then cleans the surface to be cleaned, so that the mopping function of the cleaning device 1 can be realized. The cleaning member 101 may be a mop or other components used for mopping.

[0032] Alternatively, if Figure 3 As shown, when the cleaning assembly 20 is in the descending state, the cleaning mechanism 100 can be in the first position, and the driving motor assembly 300 can drive the cleaning mechanism 100 to rotate through the transmission mechanism 200 to perform cleaning activities. Figure 4As shown, when the cleaning component 20 is in the raised state, the cleaning mechanism 100 may be in the second position, at which time the cleaning component 20 may not perform cleaning activities.

[0033] The first transmission member 210 can be relatively fixedly connected to the cleaning mechanism 100. The driving motor assembly 300 is connected to the cleaning mechanism 100 through the first transmission member 210. The driving motor assembly 300 drives the cleaning mechanism 100 to rotate relative to the device body 10 around a preset axis by driving the first transmission member 210 to rotate.

[0034] The second transmission member 220 and the device body 10 can be relatively fixed in position in the preset axis direction. By setting the first transmission member 210 and the second transmission member 220 as a threaded connection, the relative rotation of the second transmission member 220 and the first transmission member 210 can make the first transmission member 210 rise or fall along the preset axis direction, so that the first transmission member 210 can drive the cleaning mechanism 100 to rise and fall between the second position and the first position. By adjusting the direction in which the drive motor assembly 300 drives the first transmission member 210 to rotate, the cleaning mechanism 100 can be switched between the first position and the second position. Further, the drive motor assembly 300 can be electrically connected to the processor, and the processor can control the rotation direction of the drive motor assembly 300, so that the drive motor assembly 300 can control the direction in which the first transmission member 210 rotates.

[0035] The second transmission member 220 is connected between the first transmission member 210 and the one-way stopper 230. The one-way stopper 230 allows the second transmission member 220 to rotate along the preset first direction α. ​​When the cleaning mechanism 100 is in the first position, the first transmission member 210, the second transmission member 220 and the cleaning mechanism 100 can rotate synchronously along the preset first direction α, at which time the first transmission member 210 and the second transmission member 220 do not rotate relative to each other, and the cleaning mechanism 100 can remain in the first position and rotate along the preset first direction α. ​​When the cleaning mechanism 100 is in the second position or between the first position and the second position, the first transmission member 210 and the cleaning mechanism 100 can rotate relative to the second transmission member 220 by rotating along the preset first direction α, and the cleaning mechanism 100 can move downward toward the first position. When the cleaning mechanism 100 descends to the first position, the first transmission member 210 continues to rotate along the preset first direction α, and the first transmission member 210 can drive the cleaning mechanism 100 to rotate along the preset first direction α at the first position to perform cleaning work.

[0036] The one-way stopper 230 can also limit the second transmission member 220 from rotating in a preset second direction β opposite to the preset first direction α. ​​When the first transmission member 210 and the cleaning mechanism 100 rotate in the preset second direction β, the first transmission member 210 and the second transmission member 220 will rotate relative to each other. When the cleaning mechanism 100 is in the second position or between the first position and the second position, the first transmission member 210 and the cleaning mechanism 100 can rotate relative to each other with the second transmission member 220 by rotating in the preset second direction β, and the cleaning mechanism 100 can move upward toward the second position.

[0037] In some embodiments, the first transmission member 210 has an external thread 218 , and the second transmission member 220 has an internal thread 222 . In other embodiments, the first transmission member 210 has an internal thread 222 , and the second transmission member 220 has an external thread 218 .

[0038] The cleaning device 1 includes a device body 10 and a cleaning assembly 20, the cleaning assembly 20 is connected to the bottom of the device body 10, and includes a cleaning mechanism 100, a transmission mechanism 200 and a drive motor assembly 300, the transmission mechanism 200 includes a first transmission member 210, a second transmission member 220 and a one-way stop member 230, wherein the first transmission member 210 is respectively connected to the drive motor assembly 300 and the cleaning mechanism 100, the first transmission member 210 rotates with the drive motor assembly 300, the second transmission member 220 is respectively connected to the first transmission member 210 and the one-way stop member 230, and the one-way stop member 230 is configured to allow the second transmission member 220 to rotate along a preset first direction α and limit the second transmission member 220 to rotate along a preset first direction α. The member 220 rotates along a preset second direction β opposite to the preset first direction α, the first transmission member 210 and the second transmission member 220 are threadedly connected, and the driving motor assembly 300 drives the cleaning mechanism 100 to rise and fall between the second position and the first position relative to the device body 10 along the preset axis direction through the first transmission member 210 and the second transmission member 220. By setting a one-way stop member 230, the driving motor assembly 300 can drive the cleaning mechanism 100 to rotate around the preset axis and move up and down along the preset axis direction, so that the cleaning device 1 has a variety of cleaning actions, which can meet the diverse cleaning needs of different surfaces to be cleaned, and at the same time can simplify the structure of the cleaning assembly 20.

[0039] Alternatively, if Figures 2 to 4 As shown, the transmission mechanism 200 includes an elastic member 201 , and the elastic member 201 elastically abuts between the first transmission member 210 and the driving motor assembly 300 along a preset axis direction.

[0040] The elastic member 201 may be a spring, or may be elastic silicone, elastic rubber, etc. The elastic member 201 may be in a compressed state so that the first transmission member 210 and the drive motor assembly 300 tend to move away from each other. The drive motor assembly 300 and the device body 10 may be relatively fixed in position in a preset axial direction. When the cleaning mechanism 100 is in the second position or between the first position and the second position and the first transmission member 210 rotates along the preset first direction α, the elastic member 201 may promote the relative rotation and descent of the first transmission member 210 and the second transmission member 220 through elastic force. By providing the elastic member 201, the reliability of the descending movement of the first transmission member 210 and the cleaning mechanism 100 can be improved.

[0041] Alternatively, if Figure 3 , Figure 7 and Figure 8 As shown, the drive motor assembly 300 includes a drive motor 320 and a drive shaft 310, and the drive motor 320 is in transmission connection with the drive shaft 310. The elastic member 201 elastically abuts between the drive shaft 310 and the first transmission member 210. A positioning protrusion 311 is provided on the drive shaft 310. A sliding groove 211 is provided on the first transmission member 210, and the sliding groove 211 extends along a preset axis direction. The positioning protrusion 311 slides and snaps into the sliding groove 211, and when the first transmission member 210 moves relative to the device body 10 along the preset axis direction, the positioning protrusion 311 slides in the sliding groove 211 along the preset axis direction.

[0042] The first transmission member 210 can be transmission-connected between the cleaning mechanism 100 and the drive shaft 310. By setting the positioning protrusion 311 to slide in the sliding groove 211, the first transmission member 210 can be guided to slide along a preset axis direction relative to the drive shaft 310. By setting the positioning protrusion 311 to snap into the sliding groove 211, the first transmission member 210 can be restricted from being separated from the drive shaft 310, and at the same time, the first transmission member 210 and the drive shaft 310 can be kept in synchronous rotation.

[0043] Optionally, the number of the positioning protrusions 311 may be 1, 2 or 3 or more, for example, the number of the positioning protrusions 311 may be 3, 4 or 5. The sliding grooves 211 and the positioning protrusions 311 may be arranged in a one-to-one correspondence. Further, 2 or 3 or more positioning protrusions 311 may be distributed at intervals along the circumference of the drive shaft 310.

[0044] Alternatively, if Figure 3 As shown, the driving motor assembly 300 further includes a transmission gear set 302, and the transmission gear set 302 is transmission-connected between the driving motor 320 and the driving shaft 310. The driving motor 320 drives the driving shaft 310 to rotate through the transmission gear set 302.

[0045] Alternatively, if Figure 3As shown, the driving motor assembly 300 further includes a worm gear pair 301 , and the worm gear pair 301 is drivingly connected between the driving motor 320 and the transmission gear set 302 .

[0046] Alternatively, if Figure 3 As shown, the drive shaft 310 is provided with a receiving groove 312. One end of the first transmission member 210 is slidably inserted into the receiving groove 312. The elastic member 201 elastically abuts between the bottom of the receiving groove 312 and the end surface of one end of the first transmission member 210.

[0047] By providing the receiving groove 312, the first transmission member 210 can be guided to slide relative to the driving shaft 310 along the preset axis direction, and the first transmission member 210 and the driving shaft 310 are restricted from relative displacement in the direction perpendicular to the preset axis, and the elastic member 201 is restricted from being separated from between the first transmission member 210 and the driving shaft 310. In this way, the structural stability of the cleaning assembly 20 can be improved and the reliability of the descending movement can be improved.

[0048] Alternatively, if Figure 3 and Figure 8 As shown, a positioning groove 313 is formed on the bottom wall of the receiving groove 312. A positioning boss 212 is provided at one end of the first transmission member 210. One end of the elastic member 201 is inserted into the positioning groove 313, and the other end of the elastic member 201 is sleeved on the positioning boss 212.

[0049] By setting one end of the elastic member 201 to be inserted into the positioning groove 313, the relative displacement between the elastic member 201 and the driving shaft 310 in the direction perpendicular to the preset axis can be limited. By setting the other end of the elastic member 201 on the positioning boss 212, the relative displacement between the elastic member 201 and the first transmission member 210 in the direction perpendicular to the preset axis can be limited. In this way, the elastic member 201 can be positioned, thereby improving the structural stability of the cleaning assembly 20 and improving the reliability of the descending movement.

[0050] Alternatively, if Figure 3 , Figure 7 and Figure 8 As shown, the first transmission member 210 includes a body 213 and an outer cylinder 214 arranged coaxially, and an annular groove 215 opening toward the drive shaft 310 is formed between the body 213 and the outer cylinder 214. The drive shaft 310 has a peripheral wall portion 314 surrounding a receiving groove 312, and one end of the peripheral wall portion 314 close to the first transmission member 210 is slidably accommodated in the annular groove 215. One end of the body 213 close to the drive shaft 310 is slidably installed in the receiving groove 312. The sliding groove 211 is provided on the inner wall of the outer cylinder 214 facing the annular groove 215, and the positioning protrusion 311 is provided on the outer side of the peripheral wall portion 314.

[0051] By arranging the end of the peripheral wall portion 314 close to the first transmission member 210 to be slidably accommodated in the annular groove 215, the end of the peripheral wall portion 314 close to the first transmission member 210 can slide in the annular groove 215 along the preset axis direction, thereby allowing the first transmission member 210 to perform lifting and lowering movements relative to the drive shaft 310 along the preset axis direction. By arranging the sliding groove 211 on the inner wall of the outer cylinder portion 214 facing the annular groove 215 and arranging the positioning protrusion 311 on the outer side of the peripheral wall portion 314, the assembly of the cleaning component 20 can be facilitated, thereby improving the assembly efficiency.

[0052] Optionally, the positioning protrusion 311 is disposed at one end of the peripheral wall portion 314 close to the cleaning mechanism 100 .

[0053] Optionally, the number of the sliding grooves 211 may be 1, 2 or 3 or more, for example, the number of the sliding grooves 211 may be 3, 4 or 5. Furthermore, 2 or 3 or more sliding grooves 211 may be distributed at intervals along the circumference of the outer cylinder 214 .

[0054] Alternatively, if Figure 3 As shown, the cleaning assembly 20 is further provided with a limiting cover 216, which is connected to one end of the outer cylinder 214 close to the driving shaft 310 and partially covers the opening of the annular groove 215, and the positioning protrusion 311 slides along the sliding groove 211 until it stops at the limiting cover 216. The limiting cover 216 can limit the positioning protrusion 311 from leaving the annular groove 215.

[0055] By setting the limiting cover 216 to be connected to the end of the outer cylinder 214 close to the drive shaft 310 and partially covering the opening of the annular groove 215, the limiting cover 216 can play a blocking role. When the cleaning mechanism 100 descends, the first transmission member 210 and the cleaning mechanism 100 descend synchronously. When the cleaning mechanism 100 descends to the first position, the end of the limiting cover 216 close to the cleaning mechanism 100 will abut against the end of the positioning protrusion 311 away from the cleaning mechanism 100, thereby limiting the positioning protrusion 311 from being separated from the annular groove 215, so as to limit the first transmission member 210 and the drive shaft 310 from being separated from each other.

[0056] Furthermore, a groove is formed on one side of the limit cover 216 facing the outer cylinder 214, and one end of the outer cylinder 214 close to the drive shaft 310 is embedded and fixed in the groove. In this way, the connection effect between the limit cover 216 and the outer cylinder 214 can be improved. The limit cover 216 and the outer cylinder 214 can be connected by threaded fasteners, ultrasonic plastic welding, etc.

[0057] Alternatively, if Figure 3 , Figure 8 and Fig. 9As shown, the second transmission member 220 is provided with a central through hole 221, and an internal thread 222 is provided in the central through hole 221. The first transmission member 210 is movably provided in the central through hole 221, and the first transmission member 210 is provided with an external thread 218 that matches the internal thread 222. The one-way stopper 230 is provided with a receiving hole 231, and the second transmission member 220 is rotatably provided in the receiving hole 231, and the one-way stopper 230 controls the second transmission member 220 to rotate in the receiving hole 231 along a preset first direction α.

[0058] By movably arranging the first transmission member 210 in the middle through hole 221, the transmission stability of the first transmission member 210 and the second transmission member 220 can be improved. The one-way stopper 230 and the device body 10 can be arranged to be relatively fixed in position. By rotatably arranging the second transmission member 220 in the receiving hole 231, the reliability of the one-way stopper 230 controlling the rotation of the second transmission member 220 can be improved.

[0059] Optionally, the number of turns of the internal thread 222 is less than one turn, and the internal thread 222 is a multi-thread thread to improve the transmission efficiency of the first transmission member 210 and the second transmission member 220. Further, the number of turns of the external thread 218 is less than a quarter turn to reduce the transmission resistance of the first transmission member 210 and the second transmission member 220.

[0060] Alternatively, if Figure 3 , Figures 7 to 9 As shown, the second transmission member 220 is provided with a support surface 225 away from the cleaning mechanism 100. A stopper 315 is provided on the driving shaft 310, and the stopper 315 is supported on the support surface 225. The internal thread 222 is connected to the support surface 225 and extends in a direction away from the support surface 225, and a preset gap is left between the internal thread 222 and the end of the second transmission member 220 away from the stopper 315.

[0061] Furthermore, a stopper 315 is provided between the two ends of the driving shaft 310. The middle through hole 221 includes a first through hole section 223 and a second through hole section 224 connected to each other, and a support surface 225 is formed at the connection between the first through hole section 223 and the second through hole section 224. The second through hole section 224 is provided with an internal thread 222, and a preset interval is left between the internal thread 222 and the end of the second through hole section 224 away from the first through hole section 223.

[0062] By arranging the stopper 315 on the supporting surface 225, the stopper 315 can play a blocking role at the end of the second through hole section 224 away from the cleaning mechanism 100. When the first transmission member 210 and the cleaning mechanism 100 are raised, when the cleaning mechanism 100 is raised to the second position, the end of the first transmission member 210 away from the cleaning mechanism 100 will abut against the end of the stopper 315 close to the cleaning mechanism 100, thereby limiting the first transmission member 210 and the cleaning mechanism 100 from continuing to rise.

[0063] By leaving a preset interval between the internal thread 222 and the end of the second through hole section 224 away from the first through hole section 223, the internal thread 222 will not extend to the end of the second through hole section 224 away from the first through hole section 223, so that the section of the second through hole section 224 without the internal thread 222 can play a blocking role. When the first transmission member 210 and the cleaning mechanism 100 are lowered, when the cleaning mechanism 100 is lowered to the first position, the external thread 218 rotates to the end of the internal thread 222 close to the end of the cleaning mechanism 100, thereby limiting the first transmission member 210 and the cleaning mechanism 100 from continuing to descend.

[0064] In other embodiments, the middle through hole 221 includes a first through hole section 223, a second through hole section 224 and a third through hole section connected in sequence. A support surface 225 is formed at the connection between the first through hole section 223 and the second through hole section 224. A stopper 315 is provided between the two ends of the drive shaft 310, and the stopper 315 is limited above the support surface 225. The second through hole section 224 is provided with an internal thread 222 distributed throughout the second through hole section 224. The aperture size of the third through hole section is smaller than the minimum aperture size of the second through hole section 224, and the third through hole section can play a blocking role on the external thread 218, so that the external thread 218 cannot enter the third through hole section.

[0065] Alternatively, if Figure 3 , Figure 7 and Fig. 9 As shown, the cleaning assembly 20 includes a connection cover 229. The connection cover 229 is fixed to one end of the second transmission member 220 provided with the first through hole. A portion of the connection cover 229 is arranged opposite to the support surface 225, and the stopper 315 is located between a portion of the connection cover 229 and the support surface 225. By providing the connection cover 229, the stopper 315 can be limited to be located above the support surface 225.

[0066] Furthermore, a groove is formed on one side of the connection cover 229 facing the second transmission member 220, and one end of the second transmission member 220 close to the driving shaft 310 is embedded and fixed in the groove. In this way, the connection effect between the connection cover 229 and the second transmission member 220 can be improved. The connection cover 229 and the second transmission member 220 can be connected by threaded fasteners, ultrasonic plastic welding, etc.

[0067] Alternatively, if Figure 3 , Figure 7 and Fig. 9As shown, the number of the stopper 315 is at least two, and at least two stopper 315 are distributed at intervals along the circumference of the drive shaft 310. For example, the number of the stopper 315 is four, and the four stopper 315 are distributed at intervals along the circumference of the drive shaft 310. The stopper 315 includes a support portion 316 and an elastic arm 317, and the support portion 316 is connected between the elastic arm 317 and the drive shaft 310. At least one elastic arm 317 elastically abuts the support surface 225, and at least another elastic arm 317 elastically abuts the connection cover 229. In this way, the contact area between the stopper 315 and the second transmission member 220 can be reduced, thereby reducing the friction force when the drive shaft 310 and the second transmission member 220 rotate relative to each other, and at the same time, the stopper 315 can abut the support surface 225 and the connection cover 229 at the same time, reducing the shaking of the drive shaft 310 and the second transmission member 220 in the preset axis direction.

[0068] Alternatively, if Figure 4 and Fig. 9 As shown, a wear-resistant portion 226 is provided on the outer periphery of the second transmission member 220 , and the wear-resistant portion 226 abuts against the one-way stopper 230 in the accommodating hole 231 .

[0069] The second transmission member 220 can rotate relative to the one-way stopper 230. For example, when the cleaning mechanism 100 is in the first position and rotates along the preset first direction α for cleaning, the second transmission member 220 can rotate synchronously along the preset first direction α, and at this time, the second transmission member 220 can rotate relative to the one-way stopper 230. The wear-resistant portion 226 has a higher strength than other parts of the second transmission member 220, and the second transmission member 220 contacts the one-way stopper 230 through the wear-resistant portion 226. By providing the wear-resistant portion 226, the service life of the second transmission member 220 can be increased. For example, the wear-resistant portion 226 is made of metal, and other parts of the second transmission member 220 are made of plastic.

[0070] Alternatively, if Figure 2 and Figure 3 As shown, the cleaning assembly 20 includes a fixing frame 400, which is fixed to the device body 10, and the driving motor assembly 300 and the transmission mechanism 200 are installed on the fixing frame 400. Further, the fixing frame 400 can be used as a gear box to accommodate the above-mentioned transmission gear set 302.

[0071] Alternatively, if Figure 4 As shown, the cleaning assembly 20 further includes a Hall sensor 410 and a magnetic member 103 matched with the Hall sensor 410. The Hall sensor 410 is mounted on the fixing frame 400. The magnetic member 103 is disposed on the cleaning mechanism 100 or the first transmission member 210, and the Hall sensor 410 is used to sense the magnetic member 103 and trigger a preset signal.

[0072] For example, the magnetic member 103 is arranged on the cleaning mechanism 100, and the Hall sensor 410 is used to sense the magnetic member 103 to detect whether the cleaning mechanism 100 is connected to the transmission mechanism 200, so as to perform an in-situ detection on the cleaning mechanism 100. If the cleaning mechanism 100 is not connected to the transmission mechanism 200, a preset signal is triggered to remind the user. For another example, the magnetic member 103 is arranged on the cleaning mechanism 100 or the first transmission member 210, and the Hall sensor 410 is used to sense the magnetic member 103 to detect whether the cleaning mechanism 100 rises to the second position. If the cleaning mechanism 100 rises to the second position, a preset signal is triggered to control the drive motor assembly 300 to stop driving the transmission mechanism 200. In this way, the reliability of the rising movement of the cleaning mechanism 100 can be improved.

[0073] Alternatively, if Figure 3 , Figure 4 and Figure 7 As shown, the drive shaft 310 includes a ferromagnetic portion 319, and the ferromagnetic portion 319 is made of a ferromagnetic material, such as iron, nickel, cobalt, etc. The Hall sensor 410 can be arranged opposite to the ferromagnetic portion 319, and the magnetic signal emitted by the magnetic member 103 can be introduced into the Hall sensor 410 through the ferromagnetic portion 319. The ferromagnetic material helps to conduct the magnetic signal and can increase the induction reliability of the Hall sensor 410.

[0074] Alternatively, if Figure 4 As shown, the cleaning assembly 20 includes a key switch 420, which is mounted on a fixing frame 400. The cleaning assembly 20 includes a push rod 104, which is disposed on the cleaning mechanism 100 or the first transmission member 210, and the push rod 104 is used to move with the cleaning mechanism 100 or the first transmission member 210 to push the key switch 420 to trigger a preset signal.

[0075] For example, Figure 3 , Figure 4 and Figure 8 As shown, one end of the push rod 104 is fixed in the first transmission member 210. The drive shaft 310 may be provided with an avoidance hole 318, and the other end of the push rod 104 may slide in the avoidance hole 318. The key switch 420 may be arranged opposite to the end of the avoidance hole 318 away from the first transmission member 210. If the cleaning mechanism 100 rises to the second position, the other end of the push rod 104 may pass through the avoidance hole 318 and push the key switch 420, thereby triggering a preset signal to control the drive motor assembly 300 to stop driving the transmission mechanism 200. In this way, the reliability of the cleaning mechanism 100 in performing the ascending movement can be improved.

[0076] Furthermore, when the cleaning mechanism 100 rises to the second position, the push rod 104 passes through the accommodating groove 312 , the positioning groove 313 and the avoidance hole 318 from the first transmission member 210 in sequence, and the elastic member 201 is sleeved on the push rod 104 .

[0077] Furthermore, one end of the push rod 104 is fixed in the positioning boss 212 .

[0078] Optionally, the device body 10 is provided with a processor, which is coupled to the drive motor assembly 300 , and the processor is used to obtain the current value of the drive motor assembly 300 and trigger a preset signal when the current value exceeds a preset threshold.

[0079] For example, when the cleaning mechanism 100 rises to the second position, the first transmission member 210 cannot continue to rise due to position restriction, which will cause a rapid increase in the current value of the drive motor assembly 300. If the current value exceeds a preset threshold, indicating that the cleaning mechanism 100 rises to the second position, a preset signal is triggered to control the drive motor assembly 300 to stop driving the transmission mechanism 200.

[0080] Alternatively, if Figure 3 and Fig.10 As shown, the one-way stopper 230 is a one-way bearing. The one-way bearing includes a fixed portion 232 and a movable portion 233, and the movable portion 233 is movably connected to the fixed portion 232. The fixed portion 232 is relatively fixedly arranged with respect to the device body 10. The movable portion 233 surrounds and abuts against the second transmission member 220. The movable portion 233 is configured to allow the second transmission member 220 to rotate around a preset axis along a preset first direction α. ​​The movable portion 233 is also configured to limit the second transmission member 220 from rotating around a preset axis along a preset second direction β opposite to the preset first direction α.

[0081] For example, the one-way bearing includes a fixed bracket and a ball or a needle roller, the fixed portion 232 is the fixed bracket of the one-way bearing, the movable portion 233 is a ball or a needle roller, and the outer periphery of the second transmission member 220 can abut against the ball or the needle roller. Further, the second transmission member 220 includes a wear-resistant portion 226, and the wear-resistant portion 226 can abut against the movable portion 233.

[0082] For another example, the one-way bearing includes an outer ring bracket, an inner ring bracket, and a movable member located between the outer ring bracket and the inner ring bracket, and the inner ring bracket can rotate relative to the outer ring bracket through the movable member. The fixed part 232 is the outer ring bracket, the movable part 233 is the inner ring bracket, and the outer periphery of the second transmission member 220 can abut against the inner ring bracket.

[0083] Alternatively, if Figure 3 and Fig.11 As shown, there are two transmission mechanisms 200 and two cleaning mechanisms 100. The drive motor assembly 300 has a drive motor 320 and two drive shafts 310. The two drive shafts 310, the two transmission mechanisms 200 and the two cleaning mechanisms 100 are connected in a one-to-one transmission manner. The drive motor 320 can be used to drive the two drive shafts 310 to rotate.

[0084] Alternatively, if Fig.12 and Fig.13 As shown, the cleaning mechanism 100 includes a connecting portion 110, an elastic telescopic member 120 and a floating portion 130. The connecting portion 110 is fixedly arranged relative to the transmission mechanism 200. The elastic telescopic member 120 elastically abuts between the connecting portion 110 and the floating portion 130 along a preset axis direction, so that the floating portion 130 can float relative to the connecting portion 110 along the preset axis direction. The floating portion 130 may include the above-mentioned connecting seat 102 and the cleaning member 101.

[0085] The elastic expansion member 120 can be a spring, or elastic silica gel, elastic rubber, etc. When subjected to external force, the elastic member 201 undergoes elastic deformation, and a relative displacement along the preset axis direction can be generated between the connecting portion 110 and the floating portion 130 accordingly. After the elastic expansion member 120 undergoes elastic deformation, there will be a trend of returning to the non-deformed state. For example, during cleaning, the elastic expansion member 120 can be in a compressed state, and at this moment, the cleaning mechanism 100 has a trend of lengthening along the preset axis direction, so that the cleaning mechanism 100 applies pressure to the surface to be cleaned. Along with the height fluctuation of the surface to be cleaned, the elastic expansion member 120 undergoes corresponding deformation, and the length of the cleaning mechanism 100 in the preset axis direction also undergoes corresponding changes, so that the cleaning mechanism 100 can continuously keep in contact with the surface to be cleaned and apply pressure to the surface to be cleaned.

[0086] Further, the floating portion 130 is provided with a floating groove 131 extending along a preset axis direction, and the connecting portion 110 is provided with a floating protrusion 111. The floating protrusion 111 is slidably snapped into the floating groove 131 to limit the connection portion 110 and the floating portion 130 from being separated from each other. The floating protrusion 111 is slidable in the floating groove 131 along a preset axis direction to allow the connection portion 110 and the floating portion 130 to slide relative to each other along the preset axis direction.

[0087] Alternatively, if Figure 3 and Fig.13 As shown, a mounting groove 219 is provided at one end of the transmission mechanism 200 facing the cleaning mechanism 100, a magnetic component 2191 is provided at the bottom of the mounting groove 219, a magnetic component 103 is provided at one end of the cleaning mechanism 100 close to the transmission mechanism 200, and the end of the cleaning mechanism 100 close to the transmission mechanism 200 is inserted into the mounting groove 219, and the magnetic component 2191 and the magnetic component 103 are attracted and connected to each other, so that the transmission mechanism 200 is connected to the cleaning mechanism 100 through the magnetic component 2191 and the magnetic component 103.

[0088] Furthermore, the magnetic member 103 is a magnet. The magnetic attraction member 2191 is a ferromagnetic material, such as iron, nickel, cobalt and the like.

[0089] Alternatively, if Fig.13As shown, a fixing groove 112 is provided on one side of the connecting portion 110 facing the elastic member 120 , the magnetic member 103 is provided at the bottom of the fixing groove 112 , and one end of the elastic member 120 abuts against the magnetic member 103 in the fixing groove 112 .

[0090] Alternatively, if Figure 3 and Fig.13 As shown, the connecting portion 110 is located in the mounting groove 219 , and one end of the floating portion 130 close to the connecting portion 110 is located in the mounting groove 219 .

[0091] Optionally, the connecting portion 110 and the first transmission member 210 are relatively fixedly arranged, and a mounting groove 219 is formed at one end of the first transmission member 210 facing the cleaning mechanism 100 .

[0092] Optionally, the mounting groove 219 is configured to limit the relative rotation of the first transmission member 210 and the cleaning mechanism 100 around a preset axis. For example, the cross section of the mounting groove 219 perpendicular to the preset axis can be set to an ellipse, triangle, quadrilateral, pentagon, hexagon, etc., and accordingly, the cross section of the part of the cleaning mechanism 100 inserted in the mounting groove 219 perpendicular to the preset axis can match the cross section of the mounting groove 219 perpendicular to the preset axis.

[0093] To sum up, this embodiment can realize the rotation of the cleaning mechanism 100 around a preset axis and the lifting and lowering movement along the preset axis direction by driving the motor assembly 300, so that the cleaning device 1 has a variety of cleaning actions, which can meet the diverse cleaning needs of different surfaces to be cleaned, and at the same time can simplify the structure of the cleaning assembly 20.
