[0079] Embodiments of this disclosure provide a cleaning system, such as Figure 1 As shown, the cleaning system includes a cleaning device 10 and a base station 20. The cleaning device 10 can be, for example, a robotic vacuum cleaner, a robotic mop, or a robotic vacuum and mop combo; the cleaning device 10 may include a device body 11, a drive module, a sensing module, a control module, a cleaning module, an energy module, and a human-machine interaction module. The base station 20 is used to dock with the cleaning device 10, allowing it to be parked. The cleaning device 10 can perform functions such as charging, self-cleaning, docking, wastewater discharge, and water replenishment on the base station 20.

[0080] In one embodiment, the device body 11 is configured to automatically move along a target direction on a travel surface, which can be the surface to be cleaned by the cleaning device 10. If the cleaning device 10 is a sweeping and mopping robot, then the cleaning device 10 operates on the ground.

[0081] In one embodiment, the drive module includes a drive wheel assembly. The drive module can control both the left and right wheels simultaneously. For more precise control of the machine's movement, the drive module preferably includes a left drive wheel assembly and a right drive wheel assembly. The left and right drive wheel assemblies are symmetrically arranged along a transverse axis defined by the device body 11.

[0082] In one embodiment, to enable the automatic cleaning device 10 to move more stably or with greater mobility on the ground, the automatic cleaning device 10 may include one or more steering wheels; wherein, the steering wheels may be driven wheels or driving wheels, and their structural forms include, but are not limited to, casters, and the steering wheels may be located in front of the driving wheel assembly. A drive motor provides power to the driving wheel assembly and / or the steering wheels.

[0083] In one embodiment, the sensing module includes a position determination device located above the device body 11, a buffer located on the forward portion of the device body 11, and a cliff sensor and various sensing devices such as ultrasonic sensors, infrared sensors, magnetometers, accelerometers, gyroscopes, and odometers located at the bottom of the device body 11, providing the control module with various position and motion state information of the device body 11. For example, the forward portion of the device body 11 is provided with a buffer. During the cleaning process, when the drive wheel assembly propels the cleaning device 10 to walk on the ground, the buffer detects one or more objects in the travel path of the cleaning device 10 via a sensor module, such as a collision sensor. The cleaning device 10 can pass through the objects detected by the collision sensor, such as steps, obstacles, or walls, and the control drive structure causes the cleaning device 10 to respond to the objects, such as stepping over steps.

[0084] In one embodiment, the control module can combine distance and speed information fed back from sensors such as buffers, cliff sensors, ultrasonic sensors, infrared sensors, magnetometers, accelerometers, gyroscopes, and odometers to comprehensively determine the current working state of the robot vacuum cleaner, such as climbing stairs, crossing thresholds, walking on carpets, being on a cliff, stuck above or below, having a full dustbin, or being picked up. It will also provide specific next action strategies for different situations, making the cleaning device 10 work more in line with the user's requirements and providing a better user experience. Furthermore, the control module can plan the most efficient and reasonable cleaning path and cleaning method based on real-time map information drawn using SLAM (Simultaneous Localization and Mapping), which can improve the cleaning efficiency of the cleaning device 10.

[0085] In one embodiment, the energy module includes a rechargeable battery, such as a nickel-metal hydride battery or a lithium battery. The rechargeable battery may be connected to a charging control circuit, a battery pack charging temperature detection circuit, and a battery undervoltage monitoring circuit. These circuits are then connected to a microcontroller control circuit. The main unit is charged by connecting to a charging station via charging electrodes located on the side or bottom of the unit.

[0086] In one embodiment, the human-machine interaction module includes buttons on the main panel for users to select functions; it may also include a display screen and / or indicator lights and / or a speaker, which display the current status of the machine or the available functions to the user; and it may also include a mobile client application. For path navigation cleaning equipment, the mobile client can display a map of the environment where the equipment is located, as well as the machine's position, providing users with richer and more user-friendly functions.

[0087] In one embodiment, the cleaning module may include a dry cleaning module, or a dry and wet cleaning module. The dry cleaning module may include a roller brush assembly, side brushes, etc., while the wet cleaning module may include a cleaning head 12, a water tank, etc.

[0088] Currently, telescopic mechanisms are widely used in cleaning components of cleaning equipment. In related technologies, telescopic mechanisms typically employ gear transmission schemes, such as using reducers, spur gears, and cam mechanisms to transmit torque and motion. When the mop actively retracts, the retraction mechanism needs to overcome the tension spring force, increasing the motor torque requirement. Especially when the telescopic mechanism requires large torque and large turning angles, gear transmission schemes often have a large volume and are difficult to solve noise and vibration problems. Moreover, the increased tension of the tension spring further increases its volume to ensure its lifespan and torque transmission, requiring additional space.

[0089] To address the aforementioned technical problems, embodiments of this disclosure provide a cleaning device 10, such as... Figures 2-18 As shown, the cleaning device 10 includes: a device body 11, a swing arm assembly 14, a drive assembly 13, an elastic element 16, and a cleaning head 12. The cleaning head 12 is connected to the swing arm assembly 14, and the swing arm assembly 14 is rotatably connected to the device body 11 and can rotate relative to the device body 11 between a first position and a second position. When the swing arm assembly 14 is in the first position, the cleaning head 12 is in the retracted position relative to the device body 11. When the swing arm assembly 14 is in the second position, the cleaning head 12 is in the extended position relative to the device body 11. The drive assembly 13 includes a driver 133, a rotating member 132, and a connecting member 131. One end of the connecting member 131 is rotatably connected to the rotating member 132, and the other end is rotatably connected to the swing arm assembly 14. Under the drive of the driver 133, the rotating member 132 can rotate between a third position and a fourth position, thereby driving the connecting member 131 to move between a fifth position and a sixth position. When the rotating member 132 rotates toward the fourth position, the connecting member 131 moves toward the sixth position, and the connecting member 131 drives the swing arm assembly 14 to rotate toward the second position via the elastic member 16. When the rotating member 132 rotates toward the third position, the connecting member 131 moves toward the fifth position, and the connecting member 131 drives the swing arm assembly 14 to rotate toward the first position.

[0090] The cleaning device 10 disclosed herein has a swing arm assembly 14 rotatably connected to the device body 11, and the cleaning head 12, driven by the swing arm assembly 14, can be positioned relative to the device body 11 as follows: Figure 6 The retraction position shown is as follows Figure 7 As shown in the extended position, the cleaning head 12, driven by the swing arm assembly 14, can rotate relative to the device body 11 between the retracted position and the extended position, achieving edge cleaning and corner cleaning to cover more cleaning areas, reduce dead corners, and thus improve cleaning effect. When the cleaning head 12 needs to move from the retracted position to the extended position, the rotating part 132 rotates towards the fourth position under the drive of the driver 133, and the connecting part 131 moves towards the sixth position. The connecting part 131 drives the swing arm assembly 14 to rotate towards the second position through the elastic member 16. When the cleaning head 12 needs to move from the extended position to the retracted position, the rotating part 132, driven by the driver 133, moves the connecting part 131 towards the third position, and the connecting part 131 drives the swing arm assembly 14 to rotate towards the first position.

[0091] As can be seen, during the switching between the retracted and extended positions of the cleaning head 12, the cam linkage transmission structure is realized through the connector 131 and the rotating component 132. The connector 131 requires less movement space during movement, which can significantly reduce the volume of the drive component 13, thereby improving the space utilization of the cleaning device 10 and making the structure of the cleaning device 10 more compact.

[0092] It should be noted that, driven by the swing arm assembly 14, the cleaning head 12 rotates relative to the device body 11 between the retracted position and the extended position. For example, when the cleaning device 10 has a cylindrical structure, the cleaning head 12, in the extended position relative to the retracted position, is arranged radially closer to the periphery of the cleaning device 10. That is, in the thickness direction of the device body 11, the overlapping area of ​​the orthographic projection of the device body 11 and the cleaning head 12 on the preset reference plane when the swing arm assembly 14 is in the first position is greater than the overlapping area of ​​the orthographic projection of the device body 11 and the cleaning head 12 on the preset reference plane when the swing arm assembly 14 is in the second position. Therefore, by rotating the cleaning head 12 to the extended position, edge cleaning and corner cleaning can be achieved to cover more cleaning areas, reduce dead corners, and thus improve the cleaning effect.

[0093] In one embodiment, as the connector 131 moves toward the fifth position, it drives the swing arm assembly 14 to rotate toward the first position. At this time, one end of the elastic member 16 can move synchronously with the connector 131, and the other end of the elastic member 16 can move synchronously with the swing arm assembly 14. When the connector 131 drives the swing arm assembly 14 toward the sixth position through the elastic member, both ends of the elastic member 16 move synchronously with the connector 131 and the swing arm assembly 14. That is, when the connector 131 moves from the fifth position to the sixth position, the connector can drive the elastic member 16 to move synchronously. Under the elastic force of the elastic member, when the other end of the elastic member 16 moves, it can drive the swing arm assembly 14 to move synchronously.

[0094] One end of the elastic element 16 is connected to the connector 131, and the other end is connected to the swing arm body 141. When the cleaning head 12 needs to move from the retracted position to the extended position, the connector 131 pushes the end of the elastic element 16 during rotation. The elastic element 16 generates a compressive force under the pushing force of the connector 131. Under the action of the compressive force provided by the connector 131, the elastic element 16 drives the swing arm assembly 14 to rotate, thereby moving the swing arm assembly 14 towards the extended position. When the cleaning head 12 needs to move from the extended position to the retracted position, the connector 131 drives the swing arm assembly 14 to rotate towards the first position. At this time, one end of the elastic element 16 is pushed by the connector 131, and the other end is pushed by the swing arm assembly 14, causing the elastic element 16 to rotate with the swing arm assembly 14.

[0095] The elastic element 16 can be a torsion spring, which can be sleeved on the pivot portion 140 of the swing arm assembly 14, saving space for installing the elastic element 16, thereby further improving the compactness of the structure, reducing the volume, and improving the space utilization of the cleaning equipment 10. When the cleaning head 12 needs to move from the retracted position to the extended position, the connecting member 131 pushes the torsion arm of the torsion spring during rotation. The torsion arm is generated by the thrust of the connecting member 131, and the torsion spring drives the swing arm assembly 14 to rotate under the action of the torque provided by the connecting member 131, thereby moving the swing arm assembly 14 towards the second position. When the cleaning head 12 needs to move from the extended position to the retracted position, the connecting member 131 drives the swing arm assembly 14 to rotate towards the first position. At this time, one torsion arm of the torsion spring is pushed by the connecting member 131, and the other torsion arm is pushed by the swing arm assembly 14, so that the torsion spring rotates with the swing arm assembly 14.

[0096] In one embodiment, the elastic element 16 is in a compressed state whenever the swing arm assembly 14 is in any position between the first and second positions. The elastic restoring force of the elastic element 16 in the compressed state applies an elastic force to the swing arm assembly 14, causing it to rotate towards the second position. When the cleaning head 12 needs to move from the retracted position to the extended position, the connecting member 131 pushes the elastic element 16 during rotation. The elastic element 16, located between the connecting member 131 and the swing arm assembly 14, generates a compressive force due to the pushing force from the connecting member 131. Since the elastic element 16 is itself in a compressed state, it can directly drive the swing arm assembly 14 to rotate synchronously under the compressive force provided by the connecting member 131, thereby causing the swing arm assembly 14 to move towards the second position. When the cleaning head 12 needs to move from the extended position to the retracted position, the connecting member 131 drives the swing arm assembly 14 to rotate towards the first position. At this time, since the elastic element 16 is in a compressed state, one end of the elastic element 16 is pushed by the connector 131 and the other end is pushed by the swing arm assembly 14, so that the elastic element 16 and the swing arm assembly 14 rotate synchronously.

[0097] In one embodiment, the swing arm assembly 14 is configured to rotate from a second position to a first position under the action of an external force, and compress the elastic element 16 during the rotation. That is, when the cleaning head 12 is in the second position, when it is interfered with by an obstacle or other external force, it can rotate towards the first position, i.e., towards the inside of the device body 11, by compressing the elastic element 16. This provides a buffer when it contacts the obstacle, preventing damage during collision or other external force interference. When the obstacle is bypassed, or the external force is removed, or the external force is less than the elastic force of the elastic element, the swing arm assembly 14 can rotate towards the second position or return to the second position under the elastic force of the elastic element 16, meaning the cleaning head 12 can return to the second position to continue cleaning. During the rotation of the swing arm assembly 14 towards the first position, the connecting member 131 does not obstruct the rotation of the swing arm assembly 14; the swing arm assembly 14 only needs to overcome the elastic force of the elastic element 16.

[0098] Since the swing arm assembly 14 is in any position between the first and second positions, the elastic element 16 is always in a compressed state, meaning it is compressed when assembled. Therefore, when the swing arm assembly 14 is in the second position, the elastic element 16 applies an elastic force to the swing arm assembly 14, causing it to rotate away from the first position. That is, when the cleaning head 12 is interfered with by external forces such as obstacles, the cleaning head 12 will only compress the elastic element 16 and rotate towards the retracted position when the pushing force on the cleaning head 12 is greater than this elastic force. In other words, when the pushing force on the cleaning head 12 is less than this elastic force, or when the cleaning head 12 is not interfered with by external forces such as obstacles, the cleaning head 12 can stably remain in the second position under this elastic force. When the mop on the cleaning head 12 interacts with the ground, it experiences a torsional force opposite to the frictional force between the mop and the ground. This torsional force exerts a rotational force on the swing arm assembly toward a first position, potentially causing the cleaning head 12 to rotate relative to the device body 11. By making the elastic force provided by the elastic element 16 greater than the torsional force generated by the friction between the mop and the ground, the rotation of the swing arm assembly 14 toward the first position can be prevented when the mop interacts with the ground, thereby improving the stability of the cleaning head 12 during cleaning operations and thus enhancing the cleaning effect. It is understood that the magnitude of this elastic force can be set according to the type of cleaning head 12 and actual cleaning conditions, and this disclosure does not impose any limitations on it.

[0099] In one embodiment, one of the swing arm assembly 14 and the connector 131 is provided with a groove 181, and the other is provided with a slider 182, which is located in the groove 181. When the cleaning head 12 is driven by an external force to rotate the swing arm assembly 14 toward a first position, the swing arm assembly 14 and the connector 131 rotate relative to each other by sliding the slider 182 in the groove 181. The structure provided herein, in which one of the swing arm assembly 14 and the connector 131 is provided with a groove 181 and the other is provided with a slider 182, with the slider 182 located in the groove 181, will be described in detail.

[0100] In one embodiment, the swing arm assembly 14 includes a swing arm body 141 and a cam 142. The cam 142 is coaxially disposed and fixedly connected to the pivot portion 140 of the swing arm body 141. A connecting member 131 connects the rotating member 132 and the cam 142. When the rotating member 132 rotates from the fourth position to the third position, the connecting member 131 drives the cam 142 to rotate synchronously, and the swing arm body 141 rotates under the drive of the cam 142 to rotate to the first position. By setting the connecting member 131 to cooperate with the cam 142, the structure of the swing arm body 141 can be simplified, and the setting of the swing arm body 141 can be facilitated. At the same time, the cam 142 can be set to match the connecting member 131 without modifying the swing arm body 141, which can reduce production costs and improve the adaptability of the drive assembly 13.

[0101] In this configuration, the connecting member 131 moves toward the sixth position, and the connecting member 131 drives the swing arm assembly 14 to rotate synchronously toward the second position via the elastic member 16. Alternatively, the connecting member 131 can directly drive the swing arm body 141 to rotate synchronously toward the second position via the elastic member 16, or the connecting member 131 can drive the cam 16 to rotate via the elastic member 16, and the cam 16 can drive the swing arm body 141 to rotate synchronously toward the second position. By enabling the connecting member 131 to drive the swing arm assembly 14 to rotate synchronously toward the second position via the elastic member 16, that is, when the connecting member 131 begins to move toward the sixth position and starts to drive one end of the elastic member 16, the elastic member 16, due to sufficient initial compression, can directly drive the connected swing arm body 141 or cam 16 to move synchronously. This ensures that when the swing arm body 141 needs to extend, the connecting member 131 and the swing arm assembly 14 can move synchronously, thus avoiding the situation where the initial compression of the elastic member 16 is insufficient, and the connecting member 131 drives one end of the elastic member 16 to rotate synchronously. When one end begins to move, the other end does not move because the resistance on the swing arm body 141 is greater than the initial compression. The swing arm body 141 or cam 16 does not move until the elastic force generated by the connection 131 compressing the elastic element 16 exceeds the resistance. This results in a time difference between the movement of the connection 131 and the swing arm body 141 or cam 16, leading to an increase in the movement stroke of the connection 131 when the extension stroke of the swing arm body 141 is constant. This is detrimental to reducing the volume of the drive assembly 13. The initial compression of the elastic element 16 is the amount of compression it experiences when installed between the connection 131 and the swing arm assembly 14. This compression can be adjusted according to actual needs, and this disclosure does not impose any limitations on it.

[0102] The cam 142 can be fixedly connected to the pivot portion 140 of the swing arm body 141 with screws, facilitating assembly and subsequent maintenance. Multiple screws, such as two, can be used for the connection; since a torsional force is generated between the cam 142 and the swing arm body 141 when they rotate, multiple screws prevent misalignment in the rotational direction. Of course, the cam 142 and the pivot portion 140 of the swing arm body 141 can be fixedly connected by snap-fitting, bonding, welding, or it can also be a one-piece molded structure; this disclosure does not impose any limitations on this.

[0103] The rotating component 132 may include a rotating part and a connecting part. The rotating part is connected to the output shaft of the driver 133. The connecting part is radially connected to one side of the rotating part along the output shaft. The connecting component 131 is rotatably connected to the connecting part, that is, the end of the connecting component 131 is rotatably connected to a portion of the rotating component 132 and the cam 142 at a predetermined distance from the rotation axis. For example, screws or bolts are used to fix the end of the connecting component 131 to the rotating component 132 and the cam 142, so that the connecting component 131 is rotatably connected to the rotating component 132 and the cam 142. In one embodiment, one of the connecting component 131 and the rotating component 132 is provided with a socket, and the other is provided with a rod. The rod is located in the socket to rotatably connect the connecting component 131 and the rotating component 132. Of course, a rotating connection can also be achieved by using a structure of connecting holes and connecting protrusions. That is, the end of the connector 131 is provided with a connecting hole or a connecting protrusion, and the rotating part 132 and the cam 142 are provided with connecting protrusions or connecting holes. The connecting protrusion is located in the connecting hole to achieve a rotatable positioning connection. In addition, a ball joint connection can also be used to achieve a rotating connection. This disclosure does not limit this.

[0104] In one embodiment, such as Figures 8-11 As shown, the cam 142 is provided with a groove 181, and a slider 182 is provided on one end of the connecting member 131. The slider 182 is located in the groove 181. When the cleaning head 12 drives the swing arm body 141 to rotate from the extended position to the retracted position through the compression elastic member 16 under the action of external force, the groove 181 forms a clearance to the slider 182. The cam 142 slides in the groove 181 through the slider 182 and rotates relative to the connecting member 131.

[0105] Among them, such as Figures 8-11 As shown, the cam 142 can be a turntable structure, and the groove 181 can extend circumferentially along the axis of rotation and be disposed on the edge of the turntable. The groove 181 can be a through hole structure that penetrates the cam 142 in the axial direction, or a recessed groove structure that does not penetrate the cam 142.

[0106] The slider 182 on the connector 131 is arranged on one side of the connector 131 along the axial direction of the cam 142. The slider 182 can be cylindrical to reduce the frictional force in contact with the groove wall of the slide groove 181, thereby reducing wear and improving service life.

[0107] The other end of the connector 131 can be rotatably connected to the rotating part 132 via a threaded connection, which facilitates assembly and subsequent maintenance.

[0108] Among them, such as Figure 8 and Figure 9As shown, when the cleaning head 12 needs to move from the extended position to the retracted position, the rotating member 132 rotates from the fourth position to the third position under the drive of the driver 133, and then drives the cam 142 to rotate through the connecting member 131. The cam 142 drives the swing arm assembly 14 to rotate to the first position. During the driving process, the rotating member 132 and the cam 142 rotate in the same direction.

[0109] Among them, such as Figure 10 As shown, the equipment body 11 is provided with a mounting bracket 15, the swing arm assembly 14 is rotatably connected to the mounting bracket 15, and the driver 133 is mounted on the mounting bracket 15; a first pressure plate 1341 can be provided on the rotating part 132, and the first pressure plate 1341 and the mounting bracket 15 form an axial limiting installation of the rotating part 132 and the connecting part 131. The first pressure plate 1341 can be fixedly connected to the mounting bracket 15 by a threaded part, which facilitates assembly and subsequent maintenance.

[0110] In one embodiment, such as Figures 12-15 As shown, the connecting member 131 is provided with a groove 181, and the cam 142 is provided with a slider 182, which is located in the groove 181. When the swing arm assembly 14 rotates from the second position to the first position under the action of external force through compression elasticity, the cam 142 and the connecting member 131 rotate relative to each other through the slider 182 sliding in the groove 181, thus forming a clearance between the slider 182 and the cam 142.

[0111] Among them, such as Figure 12 and Figure 13 As shown, the cam 142 can be a turntable structure, and the slider 182 can be set on the edge of the turntable. The groove 181 on the connector 131 can be a through hole structure that penetrates the connector 131 in the axial direction of the turntable, or a countersunk hole structure that does not penetrate the connector 131.

[0112] The slider 182 on the cam 142 is axially disposed on one side of the cam 142. The slider 182 may be cylindrical to reduce the frictional force in contact with the groove wall of the slide groove 181, thereby reducing wear and improving service life.

[0113] The slider 182 on the cam 142 can be provided with a threaded hole. After the connecting piece 131 is sleeved on the slider 182 through the slide groove 181, the screw 136 can be used to restrict the axial separation of the connecting piece 131 relative to the cam 142, thereby making the slider 182 stably located in the slide groove 181. The other end of the connecting piece 131 can also be rotatably connected to the rotating piece 132 through a threaded part, which facilitates assembly and subsequent maintenance.

[0114] Among them, such as Figure 12 and Figure 13As shown, when the cleaning head 12 needs to move from the extended position to the retracted position, the rotating member 132 rotates from the fourth position to the third position under the drive of the driver 133, and then drives the cam 142 to rotate through the connector 131. The cam 142 drives the swing arm assembly 14 to rotate to the first position. During the driving process, the rotating member 132 and the cam 142 rotate in opposite directions.

[0115] Among them, such as Figures 12-14 As shown, the equipment body 11 is provided with a mounting bracket 15, the swing arm assembly 14 is rotatably connected to the mounting bracket 15, and the driver 133 is mounted on the mounting bracket 15; a second pressure plate 1342 can be provided on the rotating part 132, and the second pressure plate 1342 and the mounting bracket 15 form a limiting installation of the rotating part 132 in the axial direction. The second pressure plate 1342 can be fixedly connected to the mounting bracket 15 by a threaded part, which facilitates assembly and subsequent maintenance.

[0116] In one embodiment, a transmission component may be provided between the driver 133 and the rotating member 132 to realize the transmission connection between the output shaft of the driver 133 and the rotating member 132, thereby realizing the adjustment of the transmission ratio.

[0117] The driver 133 can be a drive motor, and the transmission component can be a planetary gear set to adjust the speed ratio between the drive motor and the rotating component 132. Of course, the transmission component can also be a connecting gear set, belt drive, or shaft drive, and this disclosure does not limit it.

[0118] In one embodiment, the swing arm assembly 14 includes a swing arm body 141 and a connector 131 connecting the rotating member 132 and the swing arm body 141. When the rotating member 132 rotates from the fourth position to the third position, the connector 131 rotates from the sixth position to the fifth position, causing the swing arm body 141 to rotate synchronously to the first position. By setting the connector 131 to directly cooperate with the swing arm body 141, the number of structural components in the swing arm assembly 14 can be simplified, and production costs can be reduced.

[0119] The end of the connector 131 can be rotatably connected to the rotating member 132 and the swing arm body 141 at a predetermined distance from the rotation axis. For example, screws or bolts can be used to fix the end of the connector 131 to the rotating member 132 and the swing arm body 141, so that the connector 131 is rotatably connected to the rotating member 132 and the swing arm body 141. Of course, a structure of connecting hole and connecting protrusion can also be used to achieve the rotatable connection. That is, the end of the connector 131 is provided with a connecting hole or connecting protrusion, and the rotating member 132 and the swing arm body 141 are provided with connecting protrusions or connecting holes. The connecting protrusion is located in the connecting hole to achieve a rotatable positioning connection. In addition, a ball joint connection can also be used to achieve the rotatable connection. This disclosure does not limit this.

[0120] In one embodiment, such as Figures 16-18 As shown, the swing arm body 141 is provided with a groove 181, and a slider 182 is provided on one end of the connecting member 131. The slider 182 is located in the groove 181. When the cleaning head 12 drives the swing arm body 141 to rotate from the second position to the first position through compression elasticity under the action of external force, the swing arm body 141 and the connecting member 131 rotate relative to each other by sliding in the groove 181 through the slider 182, and the groove 181 forms a clearance for the slider 182.

[0121] The groove 181 extends circumferentially along the pivot portion 140 of the swing arm body 141 and is disposed on the edge of the swing arm body 141. The groove 181 may be a through hole structure in the axial direction of the pivot portion 140, or a non-through groove structure.

[0122] The slider 182 on the connector 131 is located on the side facing the swing arm body 141. The slider 182 can be cylindrical to reduce the frictional force when in contact with the groove wall of the slide groove 181, thereby reducing wear and improving service life.

[0123] When the cleaning head 12 needs to move from the extended position to the retracted position, the rotating member 132 rotates from the fourth position to the third position under the drive of the driver 133, and then drives the swing arm body 141 to rotate to the first position through the connecting member 131; during the driving process, the rotating member 132 and the swing arm body 141 rotate in the same direction.

[0124] The mounting bracket 15 can be connected to a cover plate 155, which cooperates with the mounting bracket 15 to accommodate the swing arm assembly 14 and prevent dust, sewage and other contaminants from entering the swing arm assembly 14 and affecting its performance.

[0125] In one embodiment, the connector 131 is provided with a groove 181, and the swing arm body 141 is provided with a slider 182, which is located in the groove 181. When the swing arm assembly 14 rotates from the second position to the first position under the action of external force through compression elasticity, the swing arm body 141 and the connector 131 rotate relative to each other by sliding the slider 182 in the groove 181, and the groove 181 forms a clearance for the slider 182.

[0126] The swing arm body 141 may have a turntable structure, and the slider 182 may be disposed on the edge of the swing arm body 141. The groove 181 on the connector 131 may be a through hole structure or a non-through groove structure.

[0127] The slider 182 on the swing arm body 141 is axially arranged on the side facing the connector 131. The slider 182 can be cylindrical to reduce the frictional force when in contact with the groove wall of the slide groove 181, thereby reducing wear and improving service life.

[0128] The slider 182 on the swing arm body 141 can be provided with a threaded hole. After the connecting piece 131 is sleeved on the slider 182 through the slide groove 181, the axial separation of the connecting piece 131 relative to the swing arm body 141 can be restricted by screws, so that the slider 182 is stably located in the slide groove 181. The other end of the connecting piece 131 can also be rotatably connected to the rotating piece 132 through a threaded part, which facilitates assembly and subsequent maintenance.

[0129] When the cleaning head 12 needs to move from the extended position to the retracted position, the rotating member 132 rotates from the fourth position to the third position under the drive of the driver 133, and then directly drives the swing arm body 141 to rotate to the first position through the connecting member 131; during the driving process, the rotating member 132 and the swing arm body 141 rotate in opposite directions.

[0130] In one embodiment, when the rocker arm assembly 14 includes a rocker arm body 141 and a cam 142, and a groove 181 is provided on the cam 142 and a slider 182 is provided on the connector 131, one torsion arm of the torsion spring is connected to the rocker arm body 141 or the cam 142, and the other torsion arm is connected to the end of the connector 131 or to the slider 182. When the end of the connector 131 connected to the cam 142 is provided with a slot or hole 1310, the other torsion arm of the torsion spring is located in the slot or hole 1310. When one of the torsion arms of the torsion spring is connected to the rocker arm body 141, a locking protrusion 143 can be provided on the rocker arm body 141 to form a limiting assembly for the torsion arm.

[0131] In one embodiment, when the rocker arm assembly 14 includes a rocker arm body 141 and a cam 142, and the slide groove 181 is provided on the connector 131, one torsion arm of the torsion spring is connected to the rocker arm body 141 or the cam 142, and the other torsion arm is connected to the end of the connector 131. When one torsion arm of the torsion spring is connected to the rocker arm body 141, a locking protrusion 143 can be provided on the rocker arm body 141 to form a limiting assembly for the torsion arm. The connector 131 has a slot or hole 1310 at the end connected to the cam 142, and the other torsion arm of the torsion spring is located in the slot or hole 1310.

[0132] In one embodiment, when the swing arm assembly 14 includes a swing arm body 141, the connector 131 is directly connected to the swing arm body 141, and the slide groove 181 is provided on the swing arm body 141, one torsion arm of the torsion spring is connected to the swing arm body 141, and the other torsion arm is connected to the end of the connector 131 or to the slider 182. When the end of the connector 131 connected to the swing arm assembly 14 is provided with a slot or a hole, the other torsion arm of the torsion spring is located in the slot or hole. When one of the torsion arms of the torsion spring is connected to the swing arm body 141, a locking protrusion 143 can be provided on the swing arm body 141 to form a limiting assembly for the torsion arm.

[0133] In one embodiment, when the rocker arm assembly 14 includes a rocker arm body 141, a connector 131 is directly connected to the rocker arm body 141, and a groove 181 is provided on the connector 131, one torsion arm of the torsion spring is connected to the rocker arm body 141, and the other torsion arm is connected to the end of the connector 131. When one torsion arm of the torsion spring is connected to the rocker arm body 141, a locking protrusion 143 can be provided on the rocker arm body 141 to form a limiting assembly for the torsion arm. The end of the connector 131 connected to the cam 142 is provided with a slot or a hole, and the other torsion arm of the torsion spring is located in the slot or hole.

[0134] In one embodiment, when the swing arm assembly 14 includes a swing arm body 141 and a cam 142, the cam 142 and the swing arm assembly 14 are located on both sides of the mounting portion 152 of the mounting bracket 15, the pivot portion 140 of the swing arm assembly 14 extends into the mounting hole 154 of the mounting portion 152, and the cam 142 is fixedly connected to the pivot portion 140 of the swing arm assembly 14 by a threaded part, so as to realize the rotational connection between the swing arm assembly 14 and the mounting bracket 15.

[0135] A bearing 135 may be provided between the cam 142 and the mounting part 152 of the rocker arm assembly 14, so that the cam 142 and the mounting bracket 15 are rotatably connected.

[0136] Among them, an elastic element 16 can be respectively provided between the mounting part 152 of the mounting bracket 15 and the swing arm assembly 14 and between the mounting part 152 of the mounting bracket 15 and the cam 142. That is, a torsion spring can be respectively provided. One torsion arm of one torsion spring is connected to the swing arm body 141, and the other torsion arm is connected to the connector 131; one torsion arm of the other torsion spring is connected to the cam 142, and the other torsion arm is connected to the connector 131, which can enhance the elastic force provided by the elastic element 16.

[0137] In one embodiment, such as Figure 16 As shown, when the rotating member 132 is in the fourth position and drives the connecting member 131 to the sixth position, the two ends of the connecting member 131 are located on the radial sides of the rotation axis of the rotating member 132, that is, the rotation axis of the rotating member 132 is located between the two ends of the connecting member 131. This allows the rotating member 132 to be basically located between the two ends of the connecting member 131, thus improving the structural compactness between the rotating member 132 and the connecting member 131. Since the output shaft of the driver 133 can be used as the rotation axis of the rotating member 132, or the driver 133 can be connected to the rotation axis of the rotating member 132, the functional components such as the driver 133 connected to the rotating member 132 can be structurally set more compactly with the connecting member 131, thereby reducing the volume of the drive components and improving the space utilization of the cleaning equipment.

[0138] In one embodiment, the mounting bracket 15 is provided with a first limiting protrusion 1531 and a second limiting protrusion 1532. The first limiting protrusion 1531 and the second limiting protrusion 1532 are configured to restrict the first rotating member 132 from rotating between a third position and a fourth position, so that the first rotating member 132 can be precisely rotated to the third position or the fourth position, avoiding excessive rotation.

[0139] In one embodiment, the cleaning device 10 further includes a detection component 17, which is disposed on the device body 11 and configured to detect the position of the rotating member 132. When the rotating member 132 rotates to a third position, the detection component 17 outputs a third position signal; when the rotating member 132 rotates to a fourth position, the detection component 17 outputs a fourth position signal. By setting the detection component 17 to determine the rotation position of the rotating member 132, the position of the cleaning head 12 can be determined in the system of the cleaning device 10, thereby facilitating the drive control of the rotating member 132.

[0140] In one embodiment, the detection component 17 includes a first detection switch and a second detection switch; when the rotating member 132 rotates to a third position, the first detection switch is triggered; when the rotating member 132 rotates to a fourth position, the second detection switch is triggered.

[0141] The first detection switch is a photoelectric switch or a trigger switch, and the second detection switch is a photoelectric switch or a trigger switch. Preferably, the first and second detection switches are of the same type; however, they can also be of different types. The first and second detection switches can be respectively mounted on the mounting bracket 15.

[0142] In one embodiment, the rotating member 132 is provided with a detection unit. When the rotating member 132 rotates to the third position, the detection unit triggers a first detection switch; when the rotating member 132 rotates to the fourth position, the detection unit triggers a second detection switch. Alternatively, the rotating member 132 is provided with a first detection unit and a second detection unit. When the rotating member 132 rotates to the third position, the first detection unit triggers the first detection switch; when the rotating member 132 rotates to the fourth position, the second detection unit triggers the second detection switch.

[0143] It is understood that the detection component 17 can also detect the position of the cam 142 or the rocker arm assembly 14, and the detection component 17 can also be an encoder, Hall sensor, etc., and this disclosure does not limit it.

[0144] In one embodiment, the device body 11 is provided with a limiting structure, which is configured to restrict the rotation of the swing arm assembly 14 between a first position and a second position. By setting the limiting structure, the rotation of the swing arm assembly 14 can be restricted. Since the swing arm assembly 14 rotates by the elastic force of the elastic member 16 when it moves toward the second position, the limiting structure can limit the rotation angle of the swing arm assembly 14 under the elastic force. When the swing arm assembly 14 rotates to the second position and abuts against the limiting structure, the elastic member 16 also has elastic potential energy to drive the swing arm assembly 14 to rotate. That is, when the swing arm assembly 14 is in the second position, the elastic member 16 applies an elastic preload force to the swing arm assembly 14 in a direction away from the first position.

[0145] Specifically, by providing a limiting groove 151 on the device body 11, at least a portion of the swing arm assembly 14 is located within the limiting groove 151; in the rotation direction of the swing arm assembly 14, the groove walls at both ends of the limiting groove 151 limit the swing arm assembly 14. Through the limiting groove 151, on the one hand, the groove walls limit the rotation of the swing arm assembly 14, and on the other hand, they also accommodate the swing arm assembly 14, improving the space utilization of the cleaning device 10 and making the structure of the cleaning device 10 more compact.

[0146] Among them, such as 12~ Figure 14 As shown, the equipment body 11 is provided with a mounting bracket 15, and the swing arm assembly 14 is rotatably connected to the mounting bracket 15. A limiting groove 151 is formed on the mounting bracket 15. The limiting groove 151 formed by the mounting bracket 15 limits the rotation of the swing arm assembly 14 and also accommodates the swing arm assembly 14. At the same time, the mounting bracket 15 can protect the swing arm assembly 14.

[0147] It is understandable that the limiting structure can also be a protrusion on the device body 11, with protrusions set at both ends of the rotation range of the swing arm assembly 14 to limit the rotation range.

[0148] In one embodiment, the device body 11 is provided with two cleaning heads 12, at least one of which is rotatable relative to the device body 11 to extend outward from the device body 11. When the cleaning head 12 needs to extend or retract relative to the device body 11, the driving mechanism described above in this disclosure can be used for driving. This disclosure does not limit the number of extendable cleaning heads 12.

[0149] In one embodiment, the swing arm assembly 14 may be provided with a drive mechanism to drive the cleaning head 12 to rotate, so as to perform cleaning operations on the surface to be cleaned by rotating.

[0150] The swing arm assembly 14 can form a receiving space, and the drive mechanism can be partially or completely located in the receiving space, thereby avoiding the impact of sewage, dust, etc. on the life and stability of the drive mechanism and improving the reliability of the cleaning equipment 10.

[0151] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the invention disclosed herein. This application is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered exemplary only, and the true scope and spirit of this disclosure are indicated by the appended claims.
