Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, and more particularly to a cleaning module, cleaning equipment, and cleaning system. Background Technology

[0002] In recent years, with the improvement of people's living standards, home cleaning has gradually entered the era of automation and intelligence. The resulting cleaning equipment, such as mopping robots or sweeping and mopping robots, can free people from home cleaning work and effectively reduce their workload in home cleaning.

[0003] A typical robotic mop consists of a main body, a roller brush, and a mop. The mop can swing; for example, the mop assembly can swing to the outside of the main body during use to clean the floor outside the main body, and can be retracted after cleaning.

[0004] However, in related technologies, the rotation of the mop itself and the aforementioned oscillation are driven by different motors, which is costly, and multiple motors will occupy internal space of the equipment. Summary of the Invention

[0005] This application provides a cleaning module, cleaning equipment, and cleaning system to solve the technical problems in the related art where the rotation of the mop itself and the aforementioned oscillation are driven by different motors, resulting in high costs and multiple motors occupying internal space of the equipment.

[0006] In a first aspect, embodiments of this application provide a cleaning module applied to a cleaning device, the cleaning module comprising:

[0007] Mounting rack;

[0008] The swing arm includes a drive assembly, a rotating end, a first output end, and a second output end. The rotating end is rotatably connected to the mounting bracket. The first output end is disposed away from the rotating end and can switch between an inward position and an outward swing position by rotating the rotating end. The drive assembly is used to simultaneously drive the first output end and the second output end to rotate in the same direction.

[0009] A cleaning component, connected to the first output end, is used to clean the surface to be cleaned;

[0010] A docking component is provided on the mounting bracket. One end of the docking component has a first clearance area and the other end has a second clearance area. The first clearance area corresponds to the inward position and the second clearance area corresponds to the outward position. When the second output end corresponds to the docking component, the second output end contacts the docking component to realize the switching of the first output end between the inward position and the outward position.

[0011] When the second output end is in the first clearance area or the second clearance area, when the drive component drives the cleaning component to rotate through the first output end and the cleaning component is subjected to a frictional torque opposite to the rotation direction of the cleaning component, the frictional torque can drive the swing arm to rotate around the rotating end, so that the second output end is disengaged from the first clearance area or the second clearance area, thereby making the second output end contact the docking component.

[0012] In the cleaning module of this application embodiment, the driving component can simultaneously drive the first output end and the second output end to rotate in the same direction, so as to drive the second output end to contact the docking member. The rotating second contact end can act on the docking member, so that the second output end can move along the extension direction of the docking member to the first clearance area or the second clearance area, thereby driving the swing arm to switch between the inward position and the outward position, so that the cleaning member can switch between the inward position and the outward position.

[0013] With the above settings, the cleaning module only needs one drive source (drive component) to realize the rotation of the cleaning component and the free switching between the outward and inward positions of the cleaning component. There is no need to add an additional drive source, which reduces production costs. At the same time, it reduces the space occupied by the cleaning module in the cleaning equipment, providing more space for the layout of other components inside the cleaning equipment.

[0014] In one optional embodiment, when the second output terminal is located in the first clearance area, there is a gap between the second output terminal and the inner wall of the first clearance area; when the second output terminal is located in the second clearance area, there is a gap between the second output terminal and the inner wall of the second clearance area.

[0015] In one optional embodiment, the outer periphery of the second output terminal is provided with a first mating portion, and the docking member is provided with a second mating portion. The first mating portion can contact the second mating portion to realize the switching of the first output terminal between the retracted position and the outward swing position.

[0016] In one alternative embodiment, the first mating part is a friction wheel, and the second mating part is a friction-receiving part.

[0017] In one alternative embodiment, the surface of the friction wheel has a plurality of friction teeth, and the surface of the friction-receiving part has a plurality of hair strips.

[0018] In one alternative embodiment, the first mating part is a gear, and the second mating part is a rack.

[0019] In one alternative embodiment, the mounting bracket has a first region, a second region, and a third region connecting the first region and the second region, the first region forming a first clearance area, the second region forming a second clearance area, and the docking member being mounted in the third region.

[0020] In one optional embodiment, the first region and the second region are respectively provided with a first groove and a second groove, and the first groove and the second groove are recessed in a direction away from the second output end.

[0021] In one optional embodiment, the first groove and the second groove are respectively covered with auxiliary docking parts, and the auxiliary docking parts in the first groove and the second groove are respectively connected to the docking parts.

[0022] In one alternative embodiment, the auxiliary docking component is integrally formed with the docking component.

[0023] In one alternative embodiment, the groove walls of both the first groove and the second groove, which are parallel to the rotation axis of the second output end, are curved surfaces.

[0024] In one optional embodiment, the cleaning module further includes an elastic element, the two ends of which are rotatably connected to the mounting bracket and the swing arm, respectively.

[0025] When the second output end is in the first clearance zone or the second clearance zone, when the drive assembly drives the cleaning component to rotate through the first output end and the frictional torque on the cleaning component is less than or equal to the elastic force of the elastic element, the second output end remains within the first clearance zone or the second clearance zone; when the drive assembly drives the cleaning component to rotate through the first output end and the frictional torque on the cleaning component is greater than the elastic force of the elastic element, the frictional torque can drive the swing arm to rotate around the rotating end, so that the second output end leaves the first clearance zone or the second clearance zone, thereby making the second output end contact the docking component.

[0026] In one optional embodiment, the elastic element is a torsion spring, which includes a middle portion, a first end, and a second end. The first end is located at one end of the middle portion, and the second end is located at the other end of the middle portion. The mounting bracket includes a first connecting portion, and the swing arm includes a second connecting portion. The first end is rotatably connected to the first connecting portion, and the second end is rotatably connected to the second connecting portion.

[0027] In one alternative embodiment, the drive component has at least a first rotational speed and a second rotational speed, wherein the second rotational speed is greater than the first rotational speed;

[0028] When the drive component is at the first rotational speed, the second output terminal remains within the first clearance zone or the second clearance zone;

[0029] When the drive component changes from the first speed to the second speed, the second output terminal disengages from the first clearance area or the second clearance area and comes into contact with the docking member.

[0030] In one optional embodiment, the drive assembly includes a drive motor and a transmission gear set, wherein the drive motor is used to drive the transmission gear set to rotate, one gear in the transmission gear set is used to drive the first output end to rotate, and the other gear is used to drive the second output end to rotate.

[0031] In an optional embodiment, the cleaning module further includes a detection component disposed on the swing arm and / or the mounting bracket;

[0032] The detection component is configured to acquire the position of the swing arm to detect whether the first output terminal is in the outward swing position or the inward retraction position.

[0033] In one alternative embodiment, the second output terminal is located between the rotating end and the first output terminal.

[0034] Secondly, embodiments of this application also provide a cleaning device, including a body and a cleaning module as described in any of the foregoing claims, the cleaning module being disposed on the body.

[0060] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0061] In related technologies, some mopping robots are equipped with two motors. One motor drives the rotation of the mop itself to clean the floor. The other motor drives the mop to swing relative to the robot body, changing its position and cleaning the area outside the robot. Using different motors for both the mop rotation and the aforementioned swing is costly, and multiple motors also take up internal space.

[0062] Some other robotic mopping systems use only one motor to drive the rotation of the mop itself. During this rotation, a continuous frictional force exists between the mop and the floor, and the direction of this friction corresponds to the direction of rotation. This friction, combined with the mop's rotation, enables the mop to swing. However, this outward swing function is heavily reliant on floor friction. When the floor is smooth and friction is low, the mop's swing may fail. In other words, the outward swing function cannot be stably implemented with a single motor.

[0063] To address the aforementioned technical problems, embodiments of this application provide a cleaning module, cleaning equipment, and cleaning system. By simultaneously connecting the cleaning component and the swing end through a drive assembly, a single motor can drive the cleaning component to rotate along a first or second direction, integrating rotation and swing functions into a single drive source and simplifying the structure of the cleaning module.

[0064] Furthermore, when the cleaning component is driven to rotate in the first direction, the swing arm rotates synchronously in the first direction, causing the swing end to disengage from the inward position and move to the outward swing position along the docking member. When the cleaning component is driven to rotate in the second direction, the swing arm rotates synchronously in the second direction, causing the swing end to disengage from the outward swing position and move to the inward position along the docking member. This process avoids relying on ground friction to achieve swinging, solves the problem of swing failure on smooth surfaces, and reduces the number of motors, thereby lowering hardware costs and space requirements.

[0065] In addition, the docking component, as a mechanical guiding structure, ensures that the swing end is guided in a controlled manner during movement, thereby improving the stability and reliability of the outward swing function.

[0066] Finally, the above solution enables the cleaning module to be stably rotated outward under various ground conditions, ensuring the integrity of the cleaning area and operational efficiency.

[0067] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0068] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below with reference to the accompanying drawings. In the drawings, the same or similar reference numerals denote the same or similar devices or devices having the same or similar functions throughout. The described embodiments are some device embodiments of this application, not all device embodiments. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. Other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are all within the scope of protection of this application. The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0069] In a first aspect, embodiments of this application provide a cleaning system (not shown in the figures), including cleaning equipment and a base station. The base station is used to interface with the cleaning equipment.

[0070] Cleaning equipment can include floor scrubbers, vacuum cleaners, robotic vacuum cleaners, robotic mopping robots, and robotic vacuum and mop combos. The cleaning equipment in this application embodiment is a robot with mopping functionality, such as a robotic mopping robot or a robotic vacuum and mop combo.

[0071] After cleaning the surface, the cleaning equipment can return to the base station for charging, self-cleaning, drying, and water supply / discharge. The base station has designated parking positions for the cleaning equipment, allowing for its location and placement. A charging port is provided on the base station for charging the equipment. The base station may be equipped with a water inlet pipe and a wastewater outlet pipe to fill the clean water tank and drain the wastewater tank. A drying device may be installed on the base station to dry the cleaned equipment.

[0072] Reference Figure 1 Secondly, this application also provides a cleaning device 10, which includes a body 11 and a negative pressure fan (not shown in the figure) located on the body 11. The negative pressure fan provides negative pressure so that the cleaning device 10 can suck up dirt from the surface to be cleaned. The body 11 may be provided with a suction port facing the surface to be cleaned. Under the action of the negative pressure fan, dirt on the surface to be cleaned can be sucked into the cleaning device 10 through the suction port, thus cleaning the surface. The cleaning device 10 also includes a cleaning module 20, which may be located on the side of the body 11 facing the surface to be cleaned.

[0073] Reference Figure 2 In some embodiments, the cleaning device 10 may be provided with multiple cleaning modules 20. Each cleaning module 20 includes a cleaning component. When the cleaning component is a rotatable mop, the cleaning device 10 may be provided with two cleaning modules 20, which are located on the left and right sides of the body 11, respectively.

[0074] With the above settings, the cleaning equipment 10 has a large coverage area, which can improve the efficiency of cleaning operations and enhance the user experience.

[0075] It is understood that the cleaning module 20, located on one side of the body 11, can swing outward relative to the body 11. For example, see... Figure 1 , Figure 2 As shown, the cleaning module 20 on the right side of the body 11 can be moved to the right side of the body 11 to achieve outward swing. The outward swing cleaning module 20 can be used to clean the surface to be cleaned that is blocked by suspended obstacles, or it can be used to clean obstacles, thereby increasing the cleanable range of the cleaning equipment 10 and improving the cleaning effect.

[0076] Reference Figure 3 Thirdly, embodiments of this application also provide a cleaning module 20. The cleaning module 20 includes a mounting bracket 100. Exemplarily, the mounting bracket 100 is a rigid support structure used to support other structures.

[0077] It is understood that the mounting bracket 100 can be made of any material, for example, engineering plastics (such as polycarbonate or nylon) or metals (such as aluminum alloy or magnesium alloy). The specific material selection can be determined based on the requirements for lightweighting, strength and cost of the entire machine.

[0078] In some embodiments, the outer contour of the mounting bracket 100 may also be designed to fit the bottom space of the cleaning device 10, for example, in the form of a rectangular, circular or irregular shell structure. This application embodiment does not impose any special limitations on this.

[0079] Reference Figure 3 In some embodiments, the cleaning module 20 further includes a cleaning component. The cleaning component is used to clean the surface to be cleaned.

[0080] It is understood that the cleaning device is suitable for performing cleaning actions on the surface to be cleaned to achieve a cleaning effect. The surface to be cleaned can be a surface of varying roughness, a wall surface, or a carpet or blanket of different lengths or types, or the surface of an object to be cleaned. This application does not specifically limit the type of surface to be cleaned. The cleaning action can be vacuuming, mopping, or both simultaneously, to ensure the cleaning efficiency of the cleaning device 10.

[0081] The following explanation uses a cleaning device to perform a mopping action as an example. Examples of cleaning devices include, but are not limited to, rotating mop discs, vibrating mop pads, or wet mopping modules.

[0082] Reference Figure 3 In some embodiments, the cleaning component may rotate relative to the mounting bracket 100. For example, the cleaning component may be a mop that can rotate relative to the mounting bracket 100 to clean the surface to be cleaned.

[0083] Reference Figure 4 In some embodiments, the cleaning module 20 further includes a swing arm 300, which includes a drive assembly 310, a rotating end 320, a first output end 330, and a second output end 340. The rotating end 320 is rotatably connected to the mounting bracket 100, and the first output end 330 is disposed away from the rotating end 320. The drive assembly 310 is used to simultaneously drive the first output end 330 and the second output end 340 to rotate in the same direction.

[0084] Understandably, when the first output end 330 is positioned far from the rotating end 320, the distance between the first output end 330 and the rotating end 320 is relatively large. Thus, when the first output end 330 rotates relative to the rotating end 320, the range of rotation of the first output end 330 is larger. Based on this, when the cleaning component is connected to the first output end 330, the cleaning component can move synchronously with the outward swing of the first output end 330 to obtain a larger cleaning range, thereby improving the cleaning coverage of the cleaning device 10.

[0085] Reference Figures 4-7 In some embodiments, the first output terminal 330 has an inward position A1 ( Figure 4 and Figure 6 ) and the outer swing position A2 ( Figure 5 and Figure 7 The first output terminal 330 can switch between the inward position A1 and the outward position A2 by rotating the rotating terminal 320.

[0086] Among them, reference Figure 4 and Figure 6 The retracted position A1 refers to the spatial position corresponding to when the first output end 330 drives the cleaning component into the retracted state. At this time, the entire cleaning component is within the projection range of the cleaning device 10 body 11, or most of the cleaning component is within the projection range of the cleaning device 10 body 11, with a small portion of the edge outside the projection range of the cleaning device 10 body 11. At this time, the cleaning component can work normally, and it can also prevent the cleaning device 10 from colliding with obstacles during its movement.

[0087] Reference Figure 5 and Figure 7 The outward swing position A2 refers to the spatial position corresponding to the cleaning component after the first output end 330 drives it to swing outward. At this time, the cleaning component extends at least partially beyond the projection range of the body 11 to expand the cleaning coverage area. At this time, the cleaning component can break through the limitations of the cleaning device 10 body and clean the edges and corners of obstacles.

[0088] There is an intermediate transition area between the inward position A1 and the outward position A2. This area corresponds to the stroke segment where the first output end 330 contacts the docking part 400 and generates relative sliding.

[0089] In some embodiments, the cleaning component is connected to the first output terminal 330. For example, the cleaning component may be coaxially arranged with the first output terminal 330, and the cleaning component may rotate synchronously when the first output terminal 330 rotates, so as to achieve the cleaning function of the cleaning component.

[0090] It is understandable that the connection between the cleaning component and the first output terminal 330 can be a detachable connection. For example, one of the first output terminal 330 and the cleaning component may be equipped with a magnet, while the other may have a magnet or iron block. Magnetic attraction allows for the detachment and installation of the cleaning component and the first output terminal 330. Alternatively, the connection between the cleaning component and the first output terminal 330 can be a fixed connection, such as the cleaning component being fixedly connected to the first output terminal 330 by bolts.

[0091] Reference Figure 3 In some embodiments, the cleaning component can rotate in either the forward or reverse direction. For example, the drive assembly 310 can drive the first output terminal 330 to rotate, thereby causing the cleaning component to rotate along a first direction X1 or a second direction X2, where the first direction X1 is opposite to the second direction X2 (see reference). Figure 6 , Figure 7 ).

[0092] Reference Figure 3 In some embodiments, the drive assembly 310 may include a motor, a reduction gearbox, and an output shaft. The motor may be a brushed DC motor, a brushless DC motor (LDC), or a stepper motor. The output shaft of the drive assembly 310 is coaxial with or connected to the first output terminal 330 via a transmission mechanism (such as a gear, synchronous belt, etc.). The drive assembly 310 drives the first output terminal 330 to rotate via the output shaft, thereby driving the cleaning component to rotate.

[0093] Reference Figure 8 , Figure 9 In some embodiments, the first direction X1 and the second direction X2 are rotational directions that are opposite to each other. Both are determined by the current direction or control signal logic of the drive component 310, without the need for an additional reversing mechanism.

[0094] It should be noted that the drive component 310 can drive the first output terminal 330 and the second output terminal 340 to rotate in the same direction. For example, under the drive of the drive component 310, the first output terminal 330 and the second output terminal 340 can rotate simultaneously along the first direction X1 or simultaneously along the second direction X2.

[0095] Specifically, the first output terminal 330 and the second output terminal 340 are connected to each other or connected as a whole by other structures such as a housing. When the driving component 310 drives one of the first output terminal 330 and the second output terminal 340 to rotate relative to the rotating end 320, the other can rotate synchronously in the same direction.

[0096] It should be noted that both the first direction X1 and the second direction X2 are rotational directions. Figure 6 , Figure 7 As shown in the example, the first direction X1 is clockwise and the second direction X2 is counterclockwise.

[0097] In addition, the rotation angle range of the first output terminal 330 and the second output terminal 340 is constrained by the mounting bracket 100, and the specific angle can be set according to the swing amplitude requirements.

[0098] It is understood that the manufacturing method and materials of the swing arm 300 can be arbitrary. For example, the swing arm 300 can be a metal stamping part, an injection-molded reinforcing part, or a composite material part.

[0099] Reference Figure 8 , Figure 9 In some embodiments, the cleaning module 20 further includes a docking member 400 disposed on the mounting bracket 100.

[0100] In some embodiments, one end of the docking member 400 has a first clearance area B1, and the other end has a second clearance area B2. The first clearance area B1 corresponds to the inward position A1, and the second clearance area B2 corresponds to the outward position A2. When the second output end 340 corresponds to the docking member 400, the second output end 340 contacts the docking member 400 to realize the switching of the first output end 330 between the inward position A1 and the outward position A2.

[0101] Specifically, when the second output end 340 enters the area where the docking member 400 is located as the swing arm 300 rotates, the second output end 340 and the docking member 400 make physical contact and friction. In this way, the frictional contact between the second output end 340 and the docking member 400 can drive the swing arm 300 to rotate around the rotating end 320, thereby causing the first output end 330 to swing, and thus causing the cleaning member to switch between the inward retracted state and the outward swing state.

[0102] It is understood that the mating component 400 is a guide structure located inside the mounting bracket 100, and its extension path connects the mounting bracket 100 areas corresponding to the inward retraction position A1 and the outward swing position A2. The installation method of the mating component 400 can include, but is not limited to, embedded snap-fit, screw fastening, thermoforming riveting, or adhesive bonding. The material of the mating component 400 can be silicone, TPE, POM, or stainless steel, etc., to balance wear resistance and a low coefficient of friction. It should be noted that the mating component 400 has an arc shape, and its center is coaxial with the rotation center of the rotating end 320.

[0103] Reference Figure 6 , Figure 7 When the cleaning component contacts the surface to be cleaned and needs to switch from the retracted position A1 to the outward swing position A2, the drive assembly 310 simultaneously drives the first output terminal 330 and the second output terminal 340 to rotate in the first direction X1. At this time, the first output terminal 330 will drive the cleaning component to rotate in the same first direction X1. Since the cleaning component and the surface to be cleaned are in contact, a frictional torque opposite to the first direction X1 will be generated between the cleaning component and the surface to be cleaned. (Refer to...) Figure 8 , Figure 9 This frictional torque causes the swing arm 300 to rotate about the rotating end 320 in the second direction X2, thereby causing the second output end 340 to disengage from the first clearance area B1. Then, the second output end 340 contacts the mating member 400. The rotating second output end 340 can act on the mating member 400, allowing the second output end 340 to move along the extension direction of the mating member 400 to the second clearance area B2. During the process of the second output end 340 moving to the second clearance area B2, refer to... Figure 6 , Figure 7 The second output end 340 can drive the swing arm 300 to swing, so that the swing arm 300 can drive the first output end 330 and the cleaning component to move to the outward swing position A2. In this way, through the frictional torque between the cleaning component and the surface to be cleaned and the guidance of the docking component 400, the first output end 330 and the cleaning component can be switched from the inward position A1 to the outward swing position A2.

[0104] Reference Figure 6 , Figure 7 When the cleaning component contacts the surface to be cleaned and needs to switch from the outward swing position A2 to the inward retraction position A1, the drive assembly 310 simultaneously drives the first output terminal 330 and the second output terminal 340 to rotate in the second direction X2. At this time, the first output terminal 330 will drive the cleaning component to rotate in the second direction X2 as well. Since the cleaning component and the surface to be cleaned are in contact, a frictional torque opposite to the second direction X2 will be generated between the cleaning component and the surface to be cleaned. (Refer to...) Figure 8 , Figure 9 The frictional torque causes the swing arm 300 to rotate about the rotating end 320 in the first direction X1, thereby causing the second output end 340 to disengage from the second clearance area B2. Then, the second output end 340 contacts the mating member 400. The rotating second output end 340 can act on the mating member 400, allowing the second output end 340 to move along the extension direction of the mating member 400 to the first clearance area B1. During the process of the second output end 340 moving to the first clearance area B1, refer to... Figure 6 , Figure 7 The second output end 340 can drive the swing arm 300 to swing, so that the swing arm 300 can drive the first output end 330 and the cleaning component to move to the retracted position A1. In this way, through the frictional torque between the cleaning component and the surface to be cleaned and the guidance of the docking component 400, the first output end 330 and the cleaning component can be switched from the outward swing position A2 to the retracted position A1.

[0105] With this setup, only one drive source (drive component 310) is needed to simultaneously realize the rotation of the cleaning component and the free switching between the outward swing position A2 and the inward retraction position A1. No additional drive source is required, which reduces production costs. At the same time, it reduces the space occupied by the cleaning module 20 in the cleaning equipment 10, providing more layout space for other components inside the cleaning equipment 10.

[0106] Reference Figure 6 , Figure 7 As an optional implementation, the second output terminal 340 is located between the rotating end 320 and the first output terminal 330, and the distance between the second output terminal 340 and the rotating end 320 is less than the distance between the second output terminal 340 and the first output terminal 330.

[0107] It is understandable that the distance between the second output terminal 340 and the rotating terminal 320 is the outer swing radius of the second output terminal 340, and the distance between the first output terminal 330 and the rotating terminal 320 is the outer swing radius of the first output terminal 330.

[0108] The second output end 340 is located between the rotating end 320 and the first output end 330, meaning that the outward swing radius of the second output end 340 is smaller than that of the first output end 330. The outward swing of the second output end 340 can drive the outward swing of the first output end 330. With this setting, the small outward swing of the second output end 340 can drive the large outward swing of the first output end 330, which helps to reduce the overall volume of the cleaning module 10 while ensuring the outward swing amplitude of the first output end 330, thereby optimizing the spatial layout of the cleaning equipment.

[0109] Reference Figure 8 , Figure 9 As an optional implementation, when the second output terminal 340 is located in the first clearance area B1, there is a gap between the second output terminal 340 and the inner wall of the first clearance area B1. When the first output terminal 330 is located in the second clearance area B2, there is a gap between the second output terminal 340 and the inner wall of the second clearance area B2.

[0110] Understandably, the clearance value can be set according to manufacturing tolerances and assembly allowances, for example, it can be 0.3mm-1.5mm, in order to avoid accidental contact due to thermal expansion and contraction, assembly deviation or vibration.

[0111] With the above settings, the second output terminal 340 can idle in the first clearance area B1 or the second clearance area B2 without contacting the docking part 400, thereby avoiding accidental swinging caused by accidental disturbance or slight vibration that might cause the second output terminal 340 to accidentally touch the docking part 400.

[0112] Reference Figure 4 , Figure 5, Figure 8 as well as Figure 9 As an optional implementation, the outer periphery of the second output terminal 340 is provided with a first mating part 341, and the docking part 400 is provided with a second mating part 410. The first mating part 341 can contact the second mating part 410 to realize the switching of the first output terminal 330 between the inward position A1 and the outward position A2.

[0113] In some embodiments, the second mating portion 410 is arc-shaped, with its center coaxial with the rotation center of the rotating end 320. Thus, when the first mating portion 341 contacts the second mating portion 410, the second output end 340 can rotate around the rotating end 320 along the extension direction of the second mating portion 410, thereby enabling the first output end 330 to switch between the retracted position A1 and the outward swing position A2.

[0114] It should be noted that during the rotation of the second output end 340 around the rotating end 320 along the extending direction of the second mating portion 410, the second output end 340 maintains its rotation under the action of the drive assembly 310. After the first mating portion 341 contacts the second mating portion 410, the second mating portion 410 can provide static friction force for the movement of the first mating portion 341. The static friction force allows the first mating portion 341 to move relative to the second mating portion 410.

[0115] For example, refer to Figure 8 , Figure 9 After the second output terminal 340 disengages from the first clearance area B1, the first mating part 341 contacts the second mating part 410. The first mating part 341 and the second output terminal 340 rotate synchronously along the first direction X1, and the second mating part 410 can provide the first mating part 341 with static friction along the second direction X2. Under the action of static friction, the first mating part 341 moves along the second mating part 410 until it moves to the second clearance area B2, as shown in the reference. Figure 6 , Figure 7 At this time, the first output end 330 moves synchronously to the outward swing position A2. During this process, the interaction between the first mating part 341 and the second mating part 410 enables the second output end 340 to drive the swing arm 300 to swing, thereby using the swing arm 300 to move the first output end 330 and the cleaning component to the outward swing position A2. In this way, through the frictional torque between the cleaning component and the surface to be cleaned and the static friction between the first mating part 341 and the second mating part 410, the first output end 330 and the cleaning component can be switched from the inward position A1 to the outward swing position A2.

[0116] For example, refer to Figure 8 , Figure 9After the second output terminal 340 disengages from the second clearance area B2, the first mating part 341 contacts the second mating part 410. The first mating part 341 and the second output terminal 340 rotate synchronously along the second direction X2, and the second mating part 410 can provide the first mating part 341 with static friction along the first direction X1. Under the action of static friction, the first mating part 341 moves along the second mating part 410 until it moves to the first clearance area B1, as shown in the reference. Figure 6 , Figure 7 At this time, the first output end 330 moves synchronously to the retracted position A1. During this process, the interaction between the first mating part 341 and the second mating part 410 enables the second output end 340 to drive the swing arm 300 to swing, thereby using the swing arm 300 to move the first output end 330 and the cleaning component to the retracted position A1. In this way, through the frictional torque between the cleaning component and the surface to be cleaned and the static friction between the first mating part 341 and the second mating part 410, the first output end 330 and the cleaning component can be switched from the outward swing position A2 to the retracted position A1.

[0117] Reference Figure 9 As an optional implementation, the first mating part 341 is a friction wheel, and the second mating part 410 is a friction-receiving part.

[0118] Understandably, the friction-bearing part and the friction wheel form a frictional engagement, and the rotating friction wheel can provide power to facilitate movement on the friction-bearing part. The fixed friction-bearing part can provide a guiding function to ensure the connection stability between the second output end 340 and the docking part 400, thereby realizing the stable switching of the first output end 330 and the cleaning part between the inward position A1 and the outward swing position A2, ensuring the controllability of the swing process, and thus improving the stability and reliability of the outward swing function of the cleaning module 20.

[0119] As an optional implementation, the surface of the friction wheel has a plurality of friction teeth 342, that is, the surface of the first mating part 341 has a plurality of friction teeth 342. The surface of the friction-receiving part has a plurality of hair strips 411, that is, the surface of the second mating part 410 has a plurality of hair strips 411.

[0120] Understandably, the friction teeth 342 are raised structures on the surface of the friction wheel, used to increase the friction between the friction wheel and the friction-bearing part, and to prevent slippage between the friction wheel and the friction-bearing part during relative motion. The hairline 411 is a strip-shaped flexible structure on the surface of the friction-bearing part, used to contact the friction teeth 342 of the friction wheel.

[0121] It should be noted that the felt 411 can deform to contact the sidewall of the friction teeth 342, thereby increasing the contact area and thus increasing the static friction force between the second mating part 410 and the first mating part 341. The cross-sectional shape of the felt 411 can be rectangular, trapezoidal, or semi-circular, and its height and density can be matched according to the height and density of the friction teeth. The felt can be fixed in the mounting bracket 100 by means of double-sided tape, clips, screws, etc., to ensure stable contact and guidance between the second mating part 410 and the first mating part 341.

[0122] It should be noted that the wool strip 411 and the second mating part 410 can be a single piece or connected by adhesive. This application does not limit the scope of the embodiments in this regard, nor is it limited to the examples described above.

[0123] For example, after the second output end 340 disengages from the first clearance zone B1 and the friction wheel contacts the friction-receiving part, the friction teeth 342 rotate around the rotation center of the friction wheel along the first direction X1. Multiple friction teeth 342 mesh sequentially with multiple bristle strips 411, increasing the contact area between the friction wheel and the friction-receiving part, thus further increasing the static friction force along the second direction X2. Under the action of static friction, the friction wheel moves along the friction-receiving part until it reaches the second clearance zone B2, thereby switching the first output end 330 and the cleaning component from the retracted position A1 to the outward swing position A2.

[0124] For example, after the second output end 340 disengages from the second clearance zone B2 and the friction wheel contacts the friction-receiving part, the friction teeth 342 rotate around the rotation center of the friction wheel along the second direction X2. Multiple friction teeth 342 mesh sequentially with multiple bristle strips 411, increasing the contact area between the friction wheel and the friction-receiving part, thus further increasing the static friction force along the first direction X1. Under the action of static friction, the friction wheel moves along the friction-receiving part until it reaches the first clearance zone B1, thereby switching the first output end 330 and the cleaning component from the outward swing position A2 to the inward retraction position A1.

[0125] By engaging the friction teeth 342 with the hairline 411, the static friction between the second mating part 410 and the first mating part 341 can be increased, so as to ensure that the second output end 340 can obtain a stable moving driving force, thereby ensuring that the swing arm 300 can swing between the inward position A1 and the outward position A2.

[0126] As an optional implementation, the first mating part 341 is a gear and the second mating part 410 is a rack.

[0127] Understandably, the material of the gears can be set according to the actual situation, such as engineering plastics, metals (such as zinc alloys, stainless steel), or composite materials. The material of the rack can be the same as that of the gears, which will not be elaborated here.

[0128] It should be noted that the module, number of teeth, pressure angle and other parameters of the gears and racks in this application embodiment are not specifically limited, as long as they are compatible with each other. This application embodiment does not impose any special limitations on this.

[0129] As described above, the second mating part 410 is arc-shaped, meaning the rack is an arc-shaped rack with the rotation center of the rotating end as the center. The tooth profile of the rack matches the tooth profile of the gear, such as spur teeth, helical teeth, or herringbone teeth.

[0130] In some embodiments, the rack can be fixed to the mounting bracket 100 by means of double-sided tape, clips, screws, welding, etc., to ensure stable contact and stable guidance of the second mating part 410 to the first mating part 341.

[0131] For example, when the second output end 340 disengages from the first clearance area B1, the gear contacts and meshes with the rack, and the gear rotates along the first direction X1. Since the rack is fixed on the mounting bracket 100, the gear moves relative to the rack along the second direction X2 as it meshes with the rack, until it moves to the second clearance area B2, so as to realize the switching of the first output end 330 and the cleaning component from the retracted position A1 to the outward swing position A2.

[0132] For example, when the second output end 340 disengages from the second clearance area B2, the gear contacts and meshes with the rack, and the gear rotates along the second direction X1. Since the rack is fixed on the mounting bracket 100, the gear moves relative to the rack along the first direction X1 as it meshes with the rack, until it moves to the first clearance area B1, so as to realize the switching of the first output end 330 and the cleaning component from the outward swing position A2 to the inward retraction position A1.

[0133] The meshing contact between the gear and the rack increases the connection strength between the second mating part 410 and the first mating part 341, ensuring that the second output end 340 can obtain a stable moving driving force, thereby ensuring that the swing arm 300 can swing between the inward position A1 and the outward position A2.

[0134] Reference Figure 11 As an optional implementation, the mounting bracket 100 has a first region 110, a second region 120 and a third region 130 connecting the first region 110 and the second region 120. The first region 110 forms a first avoidance area B1 and the second region 120 forms a second avoidance area B2.

[0135] Specifically, the first region 110, the second region 120 and the third region 130 are arranged sequentially along an arc, and the third region 130 is located between the first region 110 and the second region 120, so that the first region 110 and the second region 120 can transition through the third region 130.

[0136] The first region 110 has the aforementioned first avoidance zone B1, corresponding to the inward position A1, and the second region 120 has the aforementioned second avoidance zone B2, corresponding to the outward position A2.

[0137] Understandably, in order to ensure that the second output terminal 340 can pass smoothly through the third region 130, the cross-sectional dimension of the third region 130 is larger than the outer diameter of the second output terminal 340, so as to avoid the second output terminal 340 getting stuck in the third region 130.

[0138] In some embodiments, the mating member 400 is installed within the third region 130, and the installation method includes, but is not limited to, embedded snap-fit, screw fastening, thermoforming riveting, or adhesive bonding.

[0139] Reference Figure 11 As an optional implementation, the first region 110 and the second region 120 are respectively provided with a first groove 111 and a second groove 121, and the first groove 111 and the second groove 121 are recessed in a direction away from the second output terminal 340.

[0140] It is understood that the first groove 111 and the second groove 121 can provide accommodating space for the second output terminal 340. As described above, the first region 110 forms a first clearance area B1, and the second region 120 forms a second clearance area B2. Therefore, the first groove 111 can form the first clearance area B1, and the second groove 121 can form the second clearance area B2.

[0141] When the second output terminal 340 is located in the first clearance area B1, there is a gap between the second output terminal 340 and the groove wall of the first groove 111; when the second output terminal 340 is located in the second clearance area B2, there is a gap between the second output terminal 340 and the groove wall of the second groove 121.

[0142] The above configuration allows the second output terminal 340 to remain idle at both the first groove 111 and the second groove 121 without contacting the docking member 400, thereby preventing the second output terminal 340 from accidentally contacting the docking member 400 and swinging unintentionally due to accidental disturbance or slight vibration.

[0143] It should be noted that the shapes of the first groove 111 and the second groove 121 can be rectangular grooves, arc grooves, or trapezoidal grooves, etc. The edges of the groove openings can be chamfered or rounded to avoid stress concentration damaging the second output terminal 340.

[0144] Reference Figure 10 As an optional implementation, the first groove 111 and the second groove 121 are respectively covered with auxiliary docking parts 420, and the auxiliary docking parts 420 in the first groove 111 and the second groove 121 are respectively connected to the docking parts 400.

[0145] It is understood that the auxiliary connecting piece 420 in the first groove 111 can be used to connect the inner wall of the first groove 111 to one end of the connecting piece 400, and the auxiliary connecting piece 420 in the second groove 121 can be used to connect the inner wall of the second groove 121 to the other end of the connecting piece 400.

[0146] For example, after the cleaning component drives the second output end 340 to disengage from the first clearance area B1, the second output end 340 contacts the side of the auxiliary docking component 420 closest to the docking component 400 and continues to move until it moves to the second clearance area B2 along the extension direction of the docking component 400. During this process, the auxiliary docking component 420 can assist the second output end 340 in contacting the docking component 400, avoiding the inability to contact the docking component 400 due to a large distance, and ensuring that the second output end 340 can drive the cleaning component to move from the inward position A1 to the outward position A2.

[0147] For example, after the cleaning component drives the second output end 340 to disengage from the second clearance area B2, the second output end 340 contacts the side of the auxiliary docking component 420 closest to the docking component 400 and continues to move until it moves to the first clearance area B1 along the extension direction of the docking component 400. During this process, the auxiliary docking component 420 can assist the second output end 340 in contacting the docking component 400, avoiding the inability to contact the docking component 400 due to a large distance, and ensuring that the second output end 340 can drive the cleaning component to move from the outward swing position A2 to the inward retraction position A1.

[0148] By providing auxiliary docking parts 420 in the first groove 111 and the second groove 121 respectively, the structural breakpoints between the groove area and the transition area can be reduced, making the path of the second output end 340 between the first avoidance area B1 and the second avoidance area B2 smoother, thereby improving the smoothness of the outward swing process.

[0149] As an optional implementation, the auxiliary docking member 420 is integrally formed with the docking member 400. For example, the auxiliary docking member 420 in the first groove 111 and the auxiliary docking member 420 in the second groove 121 are integrally formed with the docking member 400.

[0150] It is understandable that one-piece molding refers to the integral structure formed by the auxiliary docking component 420 and the docking component 400 through the same processing technology. This can enhance the connection strength between the auxiliary docking component 420 and the docking component 400, and ensure the continuity and integrity of the guide path. In addition, the one-piece molding setting can simplify the assembly process of the docking component 400 and the mounting bracket 100, thereby reducing costs.

[0151] As an optional implementation, the groove walls of the first groove 111 and the second groove 121, which are parallel to the rotation axis of the second output end 340, are both curved surfaces.

[0152] The groove walls of the first groove 111 and the second groove 121, which are parallel to the rotation axis of the second output end 340, can both be continuous and smooth curved surfaces. This ensures that there are no steps or edges between the first groove 111 and the third region 130, or between the second groove 121 and the third region 130, thus forming a smooth transition area. This can prevent the mating part 400 from warping or being suspended at the groove wall turning point, which would cause local stress concentration and affect the contact between the mating part 400 and the second output end 340.

[0153] It should be noted that the aforementioned curved surface can be a circular arc surface, a parabolic surface, an elliptical arc surface, or a composite curved surface formed by splicing multiple circular arcs with different curvatures. It is understood that all of the above-mentioned curved surface forms can achieve a good fit between the mating part 400 and the mounting bracket 100. This application embodiment does not limit the specific form of the curved surface.

[0154] Reference Figure 4 , Figure 5 , Figure 8 as well as Figure 9 As an optional implementation, the cleaning module 20 also includes an elastic element 500. The two ends of the elastic element 500 are rotatably connected to the mounting bracket 100 and the swing arm 300, respectively.

[0155] It is understandable that the elastic element 500 may include, but is not limited to, torsion springs, springs, etc.

[0156] As can be seen from the foregoing, referring to Figure 4 , Figure 5 as well as Figure 12 When the second output terminal 340 is in the first clearance zone B1 or the second clearance zone B2, the drive assembly 310 drives the cleaning component to rotate through the first output terminal 330, and the cleaning component will be subjected to a frictional torque provided by the surface to be cleaned. If this frictional torque is less than or equal to the elastic force of the elastic element 500, the elastic element 500 will not undergo elastic deformation. At this time, the torsion spring 510 is in the released state. The second output terminal 340 remains in a fixed position under the action of the elastic element 500, that is, the second output terminal 340 remains in the first clearance zone B1 or the second clearance zone B2.

[0157] If the frictional torque is greater than the elastic force of the elastic element 500, the frictional torque can overcome the elastic force of the elastic element 500, causing the second output end 340 to approach the mounting bracket 100. During this process, the elastic element 500 is compressed and undergoes elastic deformation. After the elastic element 500 is compressed to its maximum extent, the frictional torque causes the second output end 340 to disengage from the first clearance area B1 or the second clearance area B2 and approach the mating member 400 to contact it.

[0158] It should be noted that during the process of the cleaning component moving from the inward position A1 to the outward position A2, the elastic element 500 is in a released state in the first clearance zone B1, in a compressed state during docking with the docking component 400, and releases again to lock its position after entering the second clearance zone B2 from the docking component 400. During the process of the cleaning component moving from the outward position A2 to the inward position A1, the elastic element 500 is in a released state in the second clearance zone B2, in a compressed state during docking with the docking component 400, and releases again to lock its position after entering the first clearance zone B1 from the docking component 400.

[0159] By configuring the aforementioned elastic element 500, when the first output end 330 reaches the retracted position A1 or the outward swing position A2, the elastic element 500 uses its own elastic force to lock the mounting bracket 100 and the swing arm 300 in the retracted position A1 or the outward swing position A2, preventing the cleaning component from shifting. When a frictional torque is generated between the cleaning component and the surface to be cleaned, overcoming the elastic force of the elastic element 500, the elastic element 500 deforms synchronously, ensuring that the cleaning component can switch between the retracted position A1 and the outward swing position A2.

[0160] As an alternative implementation, the elastic element 500 is a torsion spring 510.

[0161] The torsion spring 510 can be made of stainless steel or manganese steel, and its wire diameter, number of coils, etc. can be adapted according to the frictional torque generated between the actual cleaning part and the surface to be cleaned.

[0162] Reference Figure 8 , Figure 9 as well as Figure 12 The torsion spring 510 includes a middle part 511, a first end 512 and a second end 513. The first end 512 is located at one end of the middle part 511 and the second end 513 is located at the other end of the middle part 511.

[0163] The mounting bracket 100 includes a first connecting part 140, and the swing arm 300 includes a second connecting part 350. The first end 512 is rotatably connected to the first connecting part 140, and the second end 513 is rotatably connected to the second connecting part 350.

[0164] Specifically, the middle part 511 is used to generate and transmit elastic force. The first end 512 and the second end 513 are both used to realize the rotational connection between the torsion spring 510 and the mounting bracket 100 and the swing arm 300, ensuring that the torsion spring 510 can deform during the rotation of the swing arm 300, while maintaining the connection relationship, thereby ensuring the stable output of elastic force.

[0165] In some embodiments, the first connecting portion 140 includes a first support post 141 and a first threaded member 142, and the second connecting portion 350 includes a second support post 351 and a second threaded member 352. The first end 512 and the second end 513 are both collars, respectively fitted onto the first support post 141 and the second support post 351. A rotatable connection is achieved between the first end 512 and the first support post 141, and between the second end 513 and the second support post 351, through these collars.

[0166] In some embodiments, both the first support column 141 and the second support column 351 have threaded holes. The first screw connector 142 is threadedly connected to the threaded hole of the first support column 141, and the second screw connector 352 is threadedly connected to the threaded hole of the second support column 351. The axis of the threaded hole is parallel to the rotation axis of the rotating end 320.

[0167] Understandably, the first threaded connector 142 can be a screw or bolt. The head size of the first threaded connector 142 is larger than the outer diameter of the first end 512 to prevent the first end 512 from axially disengaging from the first support 141. After the first threaded connector 142 is threadedly connected to the threaded hole of the first support 141, the head of the first threaded connector 142 abuts against the first end 512, thereby axially limiting the first end 512.

[0168] It should be noted that the shape of the first support column 141 can be cylindrical, prismatic, etc., and this application embodiment does not impose any special limitation on it. Among them, the shape of the second support column 351 is similar to that of the first support column 141, and the shape of the second screw connector 352 is similar to that of the first screw connector 142, which will not be described in detail here.

[0169] As described above, when the second output terminal 340 is in the first clearance zone B1 or the second clearance zone B2, the drive assembly 310 drives the cleaning component to rotate via the first output terminal 330, and the cleaning component is subjected to a frictional torque provided by the surface to be cleaned. If this frictional torque is less than or equal to the elastic force of the torsion spring 510, the torsion spring 510 will not undergo elastic deformation. At this time, the torsion spring 510 is in a released state. The second output terminal 340 remains in a fixed position under the action of the torsion spring 510, that is, the second output terminal 340 remains in the first clearance zone B1 or the second clearance zone B2.

[0170] Reference Figure 12If the frictional torque is greater than the elastic force of the torsion spring 510, the frictional torque can overcome the elastic force of the torsion spring 510. The second output end 340 rotates relative to the rotating end 320, causing the second output end 340 to approach the mounting bracket 100. The first end 512 and the second end 513 of the torsion spring 510 approach each other, while the first end 512 and the second end 513 rotate relative to the mounting bracket 100 and the second output end 340, respectively, until the first end 512 and the second end 513 are at their limit distance. At this time, the torsion spring 510 is in a compressed state. Then, under the action of the frictional torque, the second output end 340 disengages from the first clearance area B1 or the second clearance area B2 and approaches the mating part 400 to contact the mating part 400. During this process, the torsion spring 510 remains in a compressed state.

[0171] As an optional implementation, the drive component 310 has at least a first speed and a second speed, wherein the second speed is greater than the first speed.

[0172] For example, the first rotational speed is a lower speed, used to maintain stable rotation of the cleaning component and the state of the first output end 330 in the retracted position A1 or the outward swing position A2. The second rotational speed is a higher speed, used to provide static friction with the surface to be cleaned during the switching process, sufficient to overcome the elastic force of the elastic component 500.

[0173] It is understood that the specific values ​​of the first rotation speed and the second rotation speed can be set according to the cleaning effect of the cleaning component, the contact resistance between the docking component 400 and the second output end 340 and the elastic force of the elastic component 500 in actual application. This application embodiment does not impose any special limitations on this.

[0174] It should be noted that the specific values ​​of the first rotational speed and the second rotational speed are not limited in the embodiments of this application, but at least the second rotational speed can stably trigger the position switching of the second output terminal 340 between the first avoidance zone B1 and the second avoidance zone B2.

[0175] When the drive component 310 is at the first rotational speed, the second output terminal 340 remains within the first clearance zone B1 or the second clearance zone B2. This state corresponds to the standby or normal cleaning condition of the cleaning module 20, at which time the second output terminal 340 does not contact the docking part 400.

[0176] When the drive assembly 310 changes from the first speed to the second speed, the static friction between the cleaning component and the surface to be cleaned increases with the increase of the speed until it overcomes the elastic force of the elastic component 500 and drives the second output end 340 to disengage from the first clearance area B1 or the second clearance area B2, thereby causing the second output end 340 to contact and move with the docking component 400.

[0177] It is understood that the above process does not require an external trigger signal and is achieved solely through the rotational speed change of the drive component 310 itself. It should be noted that the process of changing from the first rotational speed to the second rotational speed can be a jump or a continuous acceleration process, as long as the time period during which it finally reaches and maintains the second rotational speed is sufficient to complete the position switch. This application embodiment does not impose any special limitations on this.

[0178] As described above, the driving direction of the drive assembly 310 between the inward position A1 and the outward position A2 is the first direction X1, and the driving direction of the drive assembly 310 between the outward position A2 and the inward position A1 is the second direction X2. The drive assembly 310 can obtain static friction in different directions by rotating forward and backward to drive the cleaning component to switch between the inward position A1 and the outward position A2.

[0179] With the above settings, this embodiment of the application can switch the cleaning component between the inward position A1 and the outward position A2 by controlling the rotation speed and forward / reverse rotation of the drive component 310. This method eliminates the need for additional brakes or sensors, reducing the complexity and cost of the cleaning module 20.

[0180] Reference Figure 13 As an optional implementation, the drive assembly 310 includes a drive motor 311 and a transmission gear set 312. The drive motor 311 is used to drive the transmission gear set 312 to rotate. One gear of the transmission gear set 312 is used to drive the first output end 330 to rotate, and the other gear is used to drive the second output end 340 to rotate.

[0181] The number of teeth, tooth height, radius, etc. of different gears can be set according to the required rotational speed relationship between the cleaning component, the first output end 330 and the second output end 340. This application embodiment does not impose any special limitations on this.

[0182] In this embodiment of the application, when the drive component 310 has a single motor output, the rotational motion of the cleaning component and the swinging motion of the swing arm 300 can be synchronized by the configuration of the drive motor 311 and the transmission gear set 312. No additional drive source is required, which reduces production costs. At the same time, it reduces the space occupied by the cleaning module 20 in the cleaning equipment 10, providing more space for the layout of other components inside the cleaning equipment 10.

[0183] As an optional implementation, the cleaning module 20 also includes a detection component disposed on the swing arm 300 and / or the mounting bracket 100.

[0184] The detection component is configured to acquire the position of the swing arm 300 to detect whether the first output terminal 330 is in the outward swing position A2 or the inward retraction position A1.

[0185] In some embodiments, the detection component can be a position sensor, which is used to sense the spatial position information of any structure in the swing arm 300, such as the first output terminal 330, the second output terminal 340, or the cleaning component 200.

[0186] For example, the position sensor can be any one of a Hall sensor, photoelectric switch, micro switch, magnetic encoder, or capacitive proximity sensor.

[0187] For example, the detection component can be rigidly connected to the swing arm 300 or installed on the swing arm 300 by means of brackets, clips, screws, etc.

[0188] By setting up a detection component, the position of the swing arm 300 can be monitored in real time. During the rotation of the cleaning component driven by the drive component 310 and the rotation of the swing arm 300, the detection component can continuously collect position signals and feed them back to the controller. The controller determines whether the swing arm 300 has stably entered the outward swing position A2 or the inward retraction position A1 based on the detection information from the detection component, and executes subsequent action commands accordingly (such as starting cleaning, pausing operation, error prompting, etc.), thereby supporting closed-loop control and preventing malfunctions such as mop offset, cleaning failure, or mechanism interference caused by position misjudgment.
