[0052] The disclosure below provides many different embodiments or examples for implementing different structures of the present application. In order to simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, these are merely examples and are not intended to limit the present application. In addition, the present application may repeat reference numbers and / or reference letters in different examples.

[0053] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and should not be understood as limiting the present application.

[0054] Please also refer to Figures 1 to 3 The present application provides a cleaning device 100. The cleaning device 100 includes a device body 10, a cleaning assembly 20, and a drive assembly 30. The cleaning assembly 20 is disposed on the device body 10 and is used to clean a work surface. The drive assembly 30 is disposed on the device body 10 and includes a first drive module 31. The first drive module 31 is connected to the cleaning assembly 20 and is used to drive the cleaning assembly 20 to rotate so that at least a portion of the cleaning assembly 20 can be raised and lowered between a first position and a second position.

[0055] That is, the cleaning assembly 20 may include a sweeping component or a wiping component. For example, the cleaning assembly 20 includes a side brush component. In some embodiments, the cleaning assembly 20 is disposed adjacent to the center of the device body 10. In some embodiments, the cleaning assembly 20 is disposed adjacent to the outer periphery of the device body 10. In some embodiments, there may be multiple cleaning assemblies 20, with the multiple cleaning assemblies 20 being spaced apart along the circumference of the device body 10.

[0056] When the cleaning assembly 20 includes a side brush component, the side brush component can be raised when mopping the floor using the cleaning device 100 to prevent the rotation of the side brush component from causing secondary contamination to the area that has been mopped or spreading specific stains (for example, liquid stains). Alternatively, when the cleaning assembly 20 includes a mopping component, the mopping component can be raised when sweeping the floor using the cleaning device 100 to prevent the mopping component from contaminating the carpet or causing secondary contamination to the area that has been mopped.

[0057] In this way, the cleaning device 100 of the present application can drive the cleaning component 20 to rotate through the first driving module 31 so that at least a part of the cleaning component 20 can be lifted and lowered between the first position and the second position, so that when the cleaning component 20 is used to mop or sweep the floor, the cleaning component 20 is lifted to avoid the cleaning component 20 causing secondary pollution to the area that has been mopped or swept.

[0058] In some embodiments, the first driving module 31 includes a first driving member 311. The first driving member 311 is configured to drive the cleaning assembly 20 to rotate in a first direction so that at least a portion of the cleaning assembly 20 is located in a first position, and to drive the cleaning assembly 20 to rotate in a second direction so that at least a portion of the cleaning assembly 20 is located in a second position, the second direction being opposite to the first direction, and the second position being higher than the first position.

[0059] The first driving member 311 may be a motor or other power equipment, which is not limited here.

[0060] The present application can drive the cleaning assembly 20 to rotate in a first direction by a motor so that at least a portion of the cleaning assembly 20 is located in a first position, and can drive the cleaning assembly 20 to rotate in a second direction by a motor so that at least a portion of the cleaning assembly 20 is located in a second position. In other words, the present application can configure a motor to control the rotation direction of the cleaning assembly 20 to be different, thereby achieving the switching of at least a portion of the cleaning assembly 20 between the first position and the second position at different heights.

[0061] The first drive module 31 also includes a first transmission mechanism 312, a power output member 313, and a selector member 314. The first drive member 311 is connected to the first transmission mechanism 312. The power output member 313 is connected to one end of the first transmission mechanism 312. The selector member 314 is connected to the exterior of the power output member 313. The first drive member 311 drives the first transmission mechanism 312 to rotate, which in turn drives the selector member 314 through the power output member 313. The selector member 314 is capable of rotating in a single direction.

[0062] Combine Figure 4 and Figure 5 The cleaning assembly 20 includes a cleaning housing 21, a cleaning member 22 and a lifting portion 23. Part of the cleaning member 22 is arranged in the cleaning housing 21. The cleaning housing 21 includes a first cover body 211 and a second cover body 212, and the first cover body 211 is fixedly connected to the power output member 313. After the first cover body 211 and the second cover body 212 are connected as a whole, there is a notch at the connection, and the notch forms the lifting portion 23. Part of the cleaning member 22 is connected to the first transmission mechanism 312 in a relatively rotatable manner inside the first cover body 211 and the second cover body 212, and a cleaning portion 221 is formed on the cleaning member 22, and the cleaning portion 221 extends outward through the lifting portion 23.

[0063] It can be understood that since part of the cleaning member 22 of the present application is connected to the first rotating mechanism 312 in a relatively rotatable manner inside the first cover body 211 and the second cover body 212, the rotation of the first rotating mechanism 312 can drive part of the cleaning member 22 to rotate, thereby driving the cleaning part 221 located outside the cleaning shell 21 to perform a lifting movement along the lifting part 23.

[0064] Specifically, the first transmission mechanism 312 may be a component composed of a plurality of meshing gears, such as Figure 3 As shown, the first transmission mechanism 312 has three gears, namely the first gear 1, the second gear 2, and the third gear 3. The first gear 1 is connected to the rotating shaft of the first driving member 311, so that the first driving member 311 can drive the first gear 1 to rotate, and the first gear 1 then drives the second gear 2 and the third gear 3 to rotate. The second gear 2 acts as a guide transmission. The rotating shaft of the third gear 3 is connected to the cleaning member 22, so that the rotation of the third gear 3 can drive the rotation of the cleaning member 22. At this time, the cleaning portion 221 of the cleaning member 22 contacts the work surface to be cleaned and performs cleaning normally.

[0065] The power output member 313 can be an output shaft sleeve, which can be connected to the rotating shaft of the third gear 3. The power transmission part 313 can play a power transmission role, transmitting the rotational force of the third gear 3 to 314, thereby driving the selection transmission member 314 to rotate.

[0066] The first cover 211 and the power output member 313 may be fixedly connected in a physical connection manner such as a snap connection or a threaded connection, which is not limited here.

[0067] The transmission member 314 is selected to support rotation in a single direction, and the transmission member 314 can be a one-way bearing.

[0068] When the first drive member 311 rotates in a second direction, which is opposite to the first direction (the first drive member 311 can be a motor), the output sleeve is locked by the one-way bearing, preventing it from rotating in the opposite direction of the motor. Instead, the output sleeve maintains the relative stationary connection between the first cover 211 and the second cover 212. At this point, while the rotation of the first transmission mechanism 312 can drive the cleaning unit 221 to rotate, the locked state between the output sleeve and the one-way bearing prevents the first cover 211 and the second cover 212 from moving, thereby maintaining the lifting function of the cleaning unit 221.

[0069] As can be understood, the first driving member 311 is connected to the first transmission mechanism 312, the power output member 313 is transmission-connected to one end of the first transmission mechanism 312, and the selection transmission member 314 is transmission-connected to the outside of the power output member 313. Therefore, when the first driving member 311 drives the first transmission mechanism 312 to rotate, the selection transmission member 314 is driven to rotate via the power output member 313. Furthermore, because the cleaning member 22 is relatively rotatably connected to the first transmission mechanism 312 within the first cover 211 and the second cover 212, the rotation of the first transmission mechanism 312 also drives the cleaning member 22 of the cleaning assembly 20 to rotate accordingly. The cleaning portion 221 is in the first position to clean the working surface, and the cleaning member 22 can rotate as a whole to complete normal cleaning work.

[0070] The cleaning member 22 may be a side brush, and the cleaning portion 221 may be a cleaning claw extending from the side brush, which may be made of a soft rubber material. The first cover 211 and the second cover 212 are respectively an upper cover and a lower cover of the side brush.

[0071] Specifically, the cleaning device 100 may be provided with an operation status monitoring module. The first driving member 311 may be electrically connected to the operation status monitoring module, so that the operation status monitoring module controls the rotation parameters (e.g., rotation direction, rotation time, rotation torque, rotation speed, etc.) of the first driving member 311, thereby achieving active lifting and lowering of the cleaning member 22.

[0072] In this way, the cleaning device 100 of the present application can realize the switching between the normal working state and the lifted non-working state of the cleaning member 22 by selecting the forward and reverse matching of the transmission member 314 and the first driving member 311, thereby realizing the active lifting and lowering of the cleaning part 221.

[0073] In some embodiments, the cleaning portion 221 is made of a soft hair material. That is, the present application can perform cleaning by making the cleaning portion 221 of the cleaning member 22 of the soft hair material.

[0074] In one embodiment, the cleaning member 22 also includes a cleaning body 222, which is connected to the cleaning portion 221. The cleaning body 222 is connected to the first transmission mechanism 312 for relative rotation inside the first cover 211 and the second cover 212. The first driving member 311 rotates in the first direction, the first transmission mechanism 312 rotates and drives the cleaning body 222 to rotate in the first direction, the transmission member 314 is selected to rotate in the first direction, and the cleaning portion 221 is in the first position.

[0075] The first driving member 311 rotates in the second direction, the first transmission mechanism 312 rotates and drives the cleaning body 222 to rotate in the second direction, the power output member 313 and the selection transmission member 314 are locked and remain stationary, the first cover body 211 and the second cover body 212 remain stationary, and the cleaning part 221 rises to the second position along the lifting part 23.

[0076] After the cleaning portion 221 is located at the second position, the first driving member 311 rotates in the first direction, the first transmission mechanism 312 rotates and drives the cleaning body 222 to rotate in the first direction, the selection transmission member 314 rotates in the first direction, and the cleaning portion 221 descends to the first position.

[0077] Specifically, the cleaning body 222 is connected to the cleaning portion 221 , which means that the cleaning portion 221 is movably connected to the cleaning body 222 , or in other words, the cleaning portion 221 can be detachably connected to the cleaning body 222 , making it easy to replace the cleaning portion 221 , which is not limited here.

[0078] That is, when the cleaning member 22 of the present application includes a cleaning portion 221 and a cleaning body 222, the first driving member 311 rotating in the first direction can drive the first transmission mechanism 312 to rotate in the first direction, thereby driving the cleaning body 222 and the selection transmission member 314 to rotate in the first direction, so that the cleaning body 222 drives the cleaning portion 221 to rotate to clean the working surface, thereby playing a cleaning role.

[0079] When the cleaning unit 221 needs to be lifted, the first driving member 311 can be controlled to rotate in the second direction, which is opposite to the first direction, so that the first driving member 311 drives the first transmission mechanism 312 to rotate in the second direction, and at the same time drives the cleaning body 222 to rotate in the second direction. The power output member 313 and the selection transmission member 314 are locked and remain stationary, and the first cover 211 and the second cover 212 remain stationary, so that the cleaning unit 221 rises to the second position along the lifting portion 23. In this way, the present application can control the rotation direction of the first driving member 311 to control the cleaning unit 221 to rise from the first position to the second position, thereby achieving the lifting of the cleaning unit 221.

[0080] When it is necessary to lower the cleaning unit 221 from the raised second position to the initial first position to continue cleaning, the first driving member 311 can be controlled to rotate in the first direction again, so that the first driving member 311 drives the first transmission mechanism 312 to rotate in the first direction as well, and at the same time drives the cleaning body 222 to rotate in the first direction, and the transmission member 314 is selected to rotate in the first direction, and the cleaning unit 221 is lowered to the first position, so that the cleaning unit 221 is lowered from the second position to the first position along the lifting portion 23. In this way, the present application can control the rotation direction of the first driving member 311 to control the cleaning unit 221 to rise from the first position to the second position, thereby lifting the cleaning unit 221, and control the cleaning unit 221 to fall from the second position to the first position, thereby lowering the cleaning unit 221.

[0081] In some embodiments of the present application, the lifting portion 23 is a slide groove, which includes an inclined guide surface 231 , and the cleaning portion 221 slides upward to the second position or downward to the first position along the guide surface 231 .

[0082] Specifically, see Figure 5 The guide surface 231 of the slide groove can be an inclined surface arranged along the edge of the first cover body 211 toward the second cover body 212.

[0083] When the first transmission mechanism 312 rotates and drives the cleaning portion 221 to rise inside the lifting portion 23, the cleaning portion 221 can be lifted to a fixed position and fixed in a lifted state after being lifted. Figure 5 and Figure 6 As shown, position B is the fixed position of the cleaning portion 221 in the lifting portion 23 after the cleaning portion 221 is lifted.

[0084] The number of the lifting parts 23 can be the same as the number of the cleaning parts 221. It can be understood that since the cleaning parts 221 extend outward through the lifting parts 23, the number of the cleaning parts 221 of the present application can be set in a one-to-one correspondence with the number of the lifting parts 23.

[0085] In another embodiment, the cleaning member 22 further includes a cleaning body 222 and a connecting portion 223, the connecting portion 223 connecting the cleaning body 222 and the cleaning portion 221, the cleaning body 222 can be relatively rotatably connected to the first transmission mechanism 312 inside the first cover body 211 and the second cover body 212, the cleaning portion 221 is fixedly connected to the connecting portion 223, and the connecting portion 223 extends outward through the lifting portion 23.

[0086] That is, the cleaning portion 221 in the cleaning member 22 of the present application may be directly connected to the cleaning body 222 , or may be indirectly connected to the cleaning body 222 through the connecting portion 223 .

[0087] Specifically, the connecting portion 223 connects the cleaning body 222 and the cleaning portion 221, meaning that the cleaning portion 221, the cleaning body 222, and the connecting portion 223 are detachably connected to each other. The cleaning portion 221 can be movably connected to the cleaning body 222 via the connecting portion 223, or in other words, the cleaning portion 221 can be detachably connected to the cleaning body 222 via the connecting portion 223, making it easy to replace the cleaning portion 221.

[0088] When the cleaning member 22 includes a connecting portion 223, the cleaning portion 221 of the cleaning member 22 can be embedded in the connecting portion 223. In detail, when the cleaning member 22 is a side brush, the cleaning body 222 is the brush holder, the cleaning portion 221 is the bristles, and the connecting portion 223 can be a component with an embedded hole, so that the bristles can be embedded in the connecting portion 223.

[0089] In some embodiments, the connecting portion is made of a flexible rubber or silicone material. The flexible rubber or silicone material has good wear resistance and anti-aging properties, can maintain good physical properties during long-term use, and extend the service life of the cleaning member 22.

[0090] During the cleaning process of the cleaning member 22 , the cleaning portion 221 may encounter hard objects or obstacles. The flexible connecting portion 223 can play a buffering role to reduce the impact and damage to the cleaning portion 221 and the cleaning body 222 .

[0091] In this way, the connecting part 223 of the present application is made of flexible rubber silicone and other materials, which not only enhances the durability and adaptability of the cleaning part 22, but also protects the cleaning part 221 and the cleaning body 222, improves the cleaning efficiency, and reduces noise and vibration.

[0092] The following describes how, when the cleaning member 22 includes the connecting portion 223 , the first driving member 311 drives the connecting portion 223 and the cleaning portion 221 of the cleaning member 22 to move upward and downward between the first position and the second position.

[0093] The first driving member 311 rotates in the second direction, the first transmission mechanism 312 rotates and drives the cleaning body 222 to rotate in the second direction, the power output member 313 and the selection transmission member 314 are locked and remain stationary, the first cover body 211 and the second cover body 212 remain stationary, and the connecting part 223 and the cleaning part 221 rise to the second position along the lifting part 23.

[0094] After the connecting part 223 and the cleaning part 221 are located in the second position, the first driving member 311 rotates in the first direction, the first transmission mechanism 312 rotates and drives the cleaning body 222 to rotate in the first direction, the transmission member 314 is selected to rotate in the first direction, and the connecting part 223 and the cleaning part 221 descend to the first position along the lifting part 23.

[0095] In detail, when the cleaning member 22 of the present application includes a cleaning portion 221, a cleaning body 222 and a connecting portion 223, the first driving member 311 rotates in the first direction to drive the first transmission mechanism 312 to rotate in the first direction, thereby driving the cleaning body 222 and the selection transmission member 314 to rotate in the first direction, so that the cleaning body 222 drives the connecting portion 223 and the cleaning portion 221 to rotate together, so that the cleaning portion 221 can clean the working surface and play a cleaning role.

[0096] When the cleaning section 221 needs to be lifted, the first driving member 311 can be controlled to rotate in the second direction, which is opposite to the first direction, so that the first driving member 311 drives the first transmission mechanism 312 to rotate in the second direction, and at the same time drives the cleaning body 222 to rotate in the second direction. The power output member 313 and the selection transmission member 314 are locked and remain stationary, and the first cover 211 and the second cover 212 remain stationary, so that the cleaning section 221 and the connecting portion 223 are lifted to the second position along the lifting portion 23. In this way, the present application can control the rotation direction of the first driving member 311 to control the cleaning section 221 and the connecting portion 223 to rise from the first position to the second position, and can lift the connecting portion 223 and the cleaning section 221 together.

[0097] When it is necessary to lower the cleaning section 221 from the raised second position to the initial first position to continue cleaning, the first driving member 311 can be controlled to rotate in the first direction again, so that the first driving member 311 drives the first transmission mechanism 312 to rotate in the first direction as well, and at the same time drives the cleaning body 222 to rotate in the first direction, and the transmission member 314 is selected to rotate in the first direction, so that the connecting portion 223 and the cleaning section 221 are lowered to the first position, so that the connecting portion 223 and the cleaning section 221 are lowered from the second position to the first position along the lifting portion 23. In this way, the present application can control the rotation direction of the first driving member 311 to control the cleaning section 221 to rise from the first position to the second position, thereby lifting the connecting portion 223 and the cleaning section 221, and controlling the connecting portion 223 and the cleaning section 221 to fall from the second position to the first position, thereby lowering the connecting portion 223 and the cleaning section 221 to the position of the initial cleaning working surface.

[0098] In which, when the cleaning member 22 includes a cleaning portion 221, a cleaning body 222 and a connecting portion 223, the lifting portion 23 can also be a slide groove, the slide groove includes an inclined guide surface 231, and the connecting portion 223 slides upward along the guide surface 231 to the second position or slides downward to the first position.

[0099] Specifically, see Figure 5 The guide surface 231 of the slide groove can be an inclined surface arranged along the edge of the first cover body 211 toward the second cover body 212.

[0100] When the first transmission mechanism 312 rotates and drives the cleaning portion 221 to rise inside the lifting portion 23, the cleaning portion 221 can be lifted to a fixed position and fixed in a lifted state after being lifted. Figure 5 and Figure 6 As shown, position B is the fixed position of the cleaning portion 221 in the lifting portion 23 after the cleaning portion 221 is lifted.

[0101] The number of the lifting parts 23 can be the same as the number of the cleaning parts 221. It can be understood that since the cleaning parts 221 extend outward through the lifting parts 23, the number of the cleaning parts 221 of the present application can be set in a one-to-one correspondence with the number of the lifting parts 23.

[0102] Also, see Figure 1 and Figure 7 The cleaning assembly 20 of the present application can slide between a retracted position and an extended position relative to the device body 10. The extended position is farther from the center of the device body 10 than the retracted position. Figure 3 The driving assembly 30 further includes a second driving module 32, which is used to drive the cleaning assembly 20 to slide between the retracted position and the extended position.

[0103] Specifically, when the cleaning assembly 20 moves from the retracted position to the extended position, the cleaning assembly 20 slides in a direction away from the center of the device body 10. When the cleaning assembly 20 moves from the extended position to the retracted position, the cleaning assembly 20 slides in a direction close to the center of the device body 10.

[0104] The second driving module 32 can drive the cleaning component 20 to slide between the retracted position and the extended position. The cleaning component 20 can expand the cleaning range by sliding to the extended position, which makes it easier for the cleaning component 20 to clean areas such as corners to reduce or avoid blind spots in the cleaning process.

[0105] In this way, the cleaning device 100 of the present application can enable the cleaning component 20 to slide between the retracted position and the extended position, making it easier for the cleaning component 20 to clean areas such as corners to reduce or avoid blind spots during cleaning.

[0106] Specifically, the second driving module 32 includes a second driving member 321, which is connected to the cleaning assembly 20. The second driving member 321 is used to provide a driving force that tends to move the cleaning assembly 20 toward the outside of the side edge of the device body 10, so that the cleaning member 22 tends to at least partially extend outside the device body 10. The second driving member 321 is used to provide a driving force that tends to move the cleaning assembly 20 toward the inside of the side edge of the device body 10, so that the cleaning assembly 20 moves toward the inside of the side edge of the device body 10, so that the cleaning assembly 20 at least partially retracts into the device body 10.

[0107] The second driving member 321 may also be a motor or other power driving device, which is not limited here.

[0108] That is to say, the present application can also use another second motor to drive the cleaning component 20 to slide as a whole between the retracted position and the extended position, so that the cleaning component 20 can clean areas such as corners to reduce or avoid blind spots in the cleaning process of the cleaning device 100, so that the cleaning device 100 can achieve more comprehensive cleaning.

[0109] In some embodiments, the cleaning device 100 also includes a transmission housing 40, which is disposed in the device body 10, at least a portion of the first drive module 31 is located inside the transmission housing 40, and a portion of the cleaning component 20 is located outside the transmission housing 40, and the cleaning component 20 is movably connected to the transmission housing 40.

[0110] It can be understood that since at least part of the first drive module 31 is located in the transmission box 40, the transmission box 40 of the present application can not only play a transmission role in allowing the cleaning component 20 to telescopically move, but also play a role in accommodating the first drive module 31, making the structural layout of the cleaning device 100 of the present application more reasonable.

[0111] Part of the cleaning assembly 20 is located outside the transmission housing 40 , and the cleaning assembly 20 is movably connected to the transmission housing 40 , that is, the cleaning assembly 20 can rotate on one side of the transmission housing 40 .

[0112] See also Figure 1 In some embodiments, a mounting bracket 11 is provided on the device body 10 . The second driving member 321 is mounted on the mounting bracket 11 . The mounting bracket 11 has a receiving groove 111 therein, and at least a portion of the transmission housing 40 is received in the receiving groove 111 .

[0113] The transmission housing 40 may be at least partially accommodated in the receiving groove 111 in the following situations: for example, the transmission housing 40 may be partially located in the receiving groove 111; for example, the transmission housing 40 may be entirely located in the receiving groove 111. By accommodating at least a portion of the transmission housing 40 in the receiving groove 111, the transmission housing 40 fully utilizes the space in the receiving groove 111, which helps optimize the spatial layout of the cleaning device 1000 and makes the cleaning device 1000 compact.

[0114] See also Figure 2 and Figure 3 In some embodiments, the device body 10 further includes a mounting shaft 12. The transmission housing 40 includes a first housing 41 and a second housing 42, with the first housing 41 and the second housing 42 connected. Positioning members 43 are provided in both the first housing 41 and the second housing 42. The ends of the mounting shaft 12 are fixed to the mounting bracket 11 via the positioning members 43 on the first housing 41 and the second housing 42, respectively. The cleaning assembly 20 can rotate about the mounting shaft 12 to slide between a retracted position and an extended position.

[0115] Specifically, the transmission housing 40 may be a frame with a hollow interior composed of a first housing 41 and a second housing 42. The positioning member 43 may be a positioning hole.

[0116] That is, the mounting shaft 12 can be fixedly mounted on the transmission housing 40 through the two positioning holes on the first housing 41 and the second housing 42, so that the cleaning assembly 20 can rotate around the mounting shaft 12, thereby enabling the cleaning assembly 20 to slide between the retracted position and the extended position.

[0117] like Figure 3 As shown, a positioning hole can be provided on the same side of the first box body 41 and the second box body 42, and the mounting shaft 12 is inserted into the positioning hole. The second driving member 311 can drive the transmission box body 40 and the cleaning component 20 to rotate around the mounting shaft 12, so as to drive the cleaning component 20 to rotate around the mounting shaft 12 to slide between the retracted position and the extended position.

[0118] The two ends of the mounting shaft 12 can be fixed to the first frame body 111 and the second frame body 112 of the mounting bracket 11 respectively through the positioning holes.

[0119] The second driving module 32 also includes a second transmission mechanism 322. The second driving member 321 is installed on the device body 10. The second transmission mechanism 322 is transmission-connected between the output shaft 3211 of the second driving member 321 and the transmission housing 40 to drive the cleaning assembly 20 to slide between the retracted position and the extended position.

[0120] Specifically, the second transmission mechanism 322 of the present application is installed on the device body 10, and the second transmission mechanism 322 can be transmission-connected between the output shaft 3211 of the second driving member 321 and the transmission box 40, that is, the output shaft 3211 of the second driving member 321 can be transmission-connected to the first end of the second transmission mechanism 322, and the second end of the second transmission mechanism 322 can be connected to the transmission box 40, and the second driving member 321 can drive the second transmission mechanism 322 to pull the transmission box 40 to slide between the retracted position and the extended position.

[0121] That is, the cleaning device 100 of the present application can drive the second transmission mechanism 322 to pull the transmission box 40 to slide between the retracted position and the extended position through the rotation of the second driving member 321, thereby driving the cleaning component 20 to slide between the retracted position and the extended position through the transmission box 40.

[0122] See also Figure 8 In some embodiments, the cleaning device 100 further includes a first elastic member 50 , one end of the first elastic member 50 is connected to the device body 10 , and the other end of the first elastic member 50 is connected to the transmission housing 40 .

[0123] The first elastic member 50 can be a tension spring, a torsion spring, etc.

[0124] Alternatively, the other end of the first elastic member 50 is directly connected to the transmission housing 40 to drive the cleaning assembly 20 from the retracted position to the extended position. Alternatively, the other end of the first elastic member 50 is indirectly connected to the transmission housing 40 to transmit a driving force to the cleaning assembly 20 to drive the cleaning assembly 20 from the retracted position to the extended position.

[0125] By providing the first elastic member 50 , the elastic force of the first elastic member 50 serves as a driving force to drive the cleaning assembly 20 to move between the retracted position and the extended position. The first elastic member 50 serves as a driving structure with a simple structure and convenient arrangement.

[0126] For example, the cleaning assembly 20 has an active retraction mode and a passive retraction mode. In the active retraction mode, the second drive motor 51 is used to drive the cleaning assembly 20 from the extended position to the retracted position. In the passive retraction mode, when the second drive motor 51 stops operating, the cleaning assembly 20, under the action of an obstacle outside the cleaning device 100, overcomes the force of the first elastic member 50 and moves from the extended position toward the retracted position. By providing the first elastic member 50, when the cleaning device 100 collides with an external obstacle, the cleaning assembly 20 can overcome the elastic force of the first elastic member 50 and move from the extended position toward the retracted position in the passive retraction mode, thereby reducing or preventing damage or jamming of the cleaning device 100. Furthermore, after the cleaning device 100 circumvents the obstacle, the first elastic member 50 automatically returns the cleaning assembly 20 to the extended position, allowing the cleaning assembly 20 to resume cleaning. The provision of the first elastic member 50 also reduces or prevents the body state or position of the cleaning device 100 from changing due to collision with an obstacle.

[0127] At this time, the first drive module 31 may also include a first transmission mechanism 312, a power output member 313 and a selection transmission member 314, the first drive member 311 is connected to the first transmission mechanism 312, the power output member 313 is transmission-connected to one end of the first transmission mechanism 312, and the selection transmission member 314 is transmission-connected to the outside of the power output member 313. The cleaning assembly 20 includes a cleaning housing 21 and a cleaning member 22, a portion of the cleaning member 22 is disposed within the cleaning housing 21, the first transmission mechanism 312 is disposed within the transmission housing 40 and is transmissionably connected between the drive shaft 3111 of the first drive member 311 and the cleaning member 22, and the selection transmission member 314 is disposed within the transmission housing 40 and is used to limit the cleaning housing 21 from rotating in a set direction. The set direction may be the second direction described above.

[0128] That is to say, the first driving module 31 of the present application can be arranged inside the transmission housing 40 , so that the layout of the cleaning device 100 is more reasonable.

[0129] See also Figure 9 In some embodiments, the transmission housing 40 includes a pivot end 44 and a free end 45, the pivot end 44 is pivotally connected to the device body 10 so that the free end 45 can rotate around the pivot end 44, and the cleaning component 20 is rotatably connected to the free end 45.

[0130] That is, one end of the transmission housing 40 of the present application is a pivot end 44, and one end of the transmission housing 40 is a free end 45 that can rotate around the pivot end 44. The pivot end 44 of the transmission housing 40 can be pivotally connected to the device body 10 via a rotating shaft, which can be the mounting shaft 12 mentioned above.

[0131] Since the cleaning assembly 20 is rotatably connected to the free end 45 of the transmission housing 40 , when the transmission housing 40 rotates around the mounting shaft 12 , the cleaning assembly 20 can be driven to slide between the retracted position and the extended position.

[0132] See also Figure 9 In some embodiments, the second transmission mechanism 322 includes a tensile member 3221 and a driving element 3222, the driving element 3222 is connected to the output shaft 3211 of the second driving member 321, one end of the tensile member 3221 is connected to the driving element 3222 and the other end of the tensile member 3221 is connected to the transmission housing 40, and the driving element 3222 is suitable for winding the tensile member 3221 around the driving element 3222 and for releasing the tensile member 3221.

[0133] In one embodiment, the tensioning member 3221 includes a wire harness, and the driving element 3222 includes a pulley. One end of the wire harness is connected to the free end 45, and the other end of the wire harness is wound around the pulley. The output shaft 3211 of the second driving member 321 is connected to the pulley to drive the pulley to rotate and wind or release the wire harness.

[0134] It should be noted that when the wire harness is wound by the spool, the tension generated by the wire harness can overcome the elastic force of the first elastic member 50, pulling the free end 45 of the transmission housing 40 toward the inner side of the side edge 11 of the device body 10 to rotate, thereby driving the cleaning assembly 20 to move toward the inner side of the side edge 11 of the device body 10, thereby retracting the cleaning assembly 20 into the device body 10. When the spool releases the wire harness, the tension of the wire harness on the free end 45 of the transmission housing 40 can be removed, and the free end 45 can rotate toward the outer side of the side edge 11 of the device body 10 under the elastic force of the first elastic member 50, thereby driving the cleaning assembly 20 to extend outside the device body 10.

[0135] The first housing 41 may be provided with a mounting hole 411, and the second housing 42 may be provided with a positioning portion 421 corresponding to the mounting hole 411. The pulley is fixed to the output shaft 3211 of the second driving member 321. The first end of the wiring harness is fixedly connected between the first housing 41 and the second housing 42 by clamping the mounting hole 411 and the positioning portion 421. The second end of the wiring harness is connected to the first end of the pulley, and the second end of the pulley is connected to the second driving member 321. The second driving member 321 can drive the pulley to rotate, thereby lengthening or shortening the wiring harness.

[0136] Specifically, see Figure 10 When the cleaning device 100 switches from cleaning corners or blind spots to normal cleaning, the second driving member 321 can drive the wire wheel to rotate in the third direction, shortening the wire harness and pulling the cleaning assembly 20 to swing to the retracted position 1. Figure 1At this time, the cleaning component 20 retracts to a retracted position close to the device body 10 and maintains its position relative to the device body 10.

[0137] When the cleaning device 100 needs to clean the corner area or the dead angle area from the normal cleaning state, the second driving member 321 can rotate in the reverse direction, that is, the second driving member 321 can drive the wire wheel to rotate in the fourth direction, which is opposite to the third direction. Figure 7 At this time, the cleaning component 20 can be swung outward to the extended position 2 relative to the device body 10.

[0138] In this way, the cleaning device 100 of the present application can drive the pulley to rotate and control the rotation direction through the second driving member 321 so that the pulley can wind the wire harness or release the wire harness, making the wire harness longer or shorter, and realizing the sliding of the cleaning component 20 between the retracted position and the extended position.

[0139] In some embodiments, the device body 10 is provided with a guide sleeve for defining the extension direction of the wire harness, through which the wire harness is threaded. The guide sleeve allows the wire harness to extend inward of the side edge of the device body 10 along the rotation direction of the free end 45. This ensures that when the reel winds the wire harness, the pulling force exerted by the wire harness on the free end 45 is directed inward of the side edge of the device body 10. The guide sleeve also prevents the wire harness from becoming tangled or entangled in the device body 10.

[0140] See also Figure 3 In some embodiments, the second driving module 32 further includes a second elastic member 323. The second elastic member 323 is sleeved on the mounting shaft 12, a first end of the second elastic member 323 is fixedly connected to the mounting bracket 11, and a second end of the second elastic member 323 is fixedly connected to the transmission housing 40.

[0141] Specifically, the mounting bracket 11 may include a first frame 112 and a second frame 113. The first end of the second elastic member 323 may be fixedly connected to the first frame 112 or the second frame 113.

[0142] The second end of the second elastic member 323 is fixedly connected to the transmission housing 40 , which means that the second end of the second elastic member 323 can be fixedly connected to the first housing 41 , and the second end of the second elastic member 323 can also be fixedly connected to the second housing 42 .

[0143] The second elastic member 323 may be a torsion spring, or other parts, which are not limited here.

[0144] In other words, a torsion spring is mounted on the mounting shaft 12, and the torsion spring can release torsional energy as the mounting shaft 12 rotates. The torsion spring can be initially compressed and has accumulated torsional energy. When the cleaning device 100 needs to be swung outward to clean corners or blind spots, the first transmission mechanism 312 and the cleaning assembly 20 can rotate under the torsion force of the torsion spring, allowing the cleaning assembly 20 to quickly swing outward to the outside of the device body 10 to clean corners or blind spots.

[0145] Please combine Figure 7 At this time, the first transmission mechanism 312 and the cleaning assembly 20 can be swung outward to the extended position 2 under the elastic force of the second elastic member 323.

[0146] When the cleaning assembly 20 can swing to the extended position 2 under the elastic force of the second elastic member 323, if the cleaning assembly 20 hits an obstacle, the first transmission mechanism 312 and the cleaning assembly 20 can passively rebound to the inside of the side brush cleaning device 100. It can be understood that, as Figure 7 As shown, when the wire harness is in the released state, the elastic force of the second elastic member 323 causes the first transmission mechanism 312 and the cleaning assembly 20 to swing outward.

[0147] In addition, when the cleaning assembly 20 encounters an obstacle during rotation, the obstacle can be detected by a sensor, and the sensor can then control the second driving member 321 to rotate in the opposite direction of the initial rotation, so that the second transmission mechanism 322 can drive the second cleaning assembly 20 to rotate and retract to the retracted position 1, thereby quickly avoiding the obstacle. The sensor for detecting obstacles installed on the cleaning device 100 can be an infrared sensor, an ultrasonic sensor, a laser sensor, a visual sensor (camera), or some type of contact sensor.

[0148] See also Figure 10 , the present application also provides a cleaning device 1000, which includes the cleaning device 100 of any one of the above embodiments.

[0149] The cleaning device 1000 may be, for example, a sweeping robot or other device, which is not limited here.

[0150] In this way, the cleaning device 100 in the cleaning equipment 1000 of the present application can drive the cleaning component 20 to rotate through the first driving module 31 so that at least a part of the cleaning component 20 can be lifted and lowered between the first position and the second position, so that when the cleaning component 20 is used to mop or sweep the floor, the cleaning component 20 is lifted to avoid the cleaning component 20 causing secondary pollution to the area that has been mopped or swept.

[0151] In addition, the present application allows the cleaning assembly 20 to be retracted into the robot to avoid obstacles when the robot encounters obstacles while cleaning with the cleaning member 22. When the robot needs to clean blind spots with the cleaning member 22, the cleaning assembly 20 can be extended outward to the outside of the robot to better cover blind spots.

[0152] It should be noted that in order to achieve the extension and retraction of the side brush gear box assembly 10 and the side brush assembly 20, the relevant technology adopts a cam to achieve extension and retraction, which results in the side brush device of the sweeping robot being larger and the weight of the sweeping robot being heavier, which is not conducive to the miniaturization and lightweight design of the sweeping robot. However, the present application does not require the setting of a cam to achieve the extension and retraction of the cleaning assembly 20, which is conducive to the miniaturization and lightweight design of the sweeping robot.

[0153] The above embodiments merely illustrate several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art could make various modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
