[0093] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0094] The following is for reference. Figures 1-4 The present invention describes a cleaning module 100, a cleaning device, and a cleaning system according to embodiments thereof.

[0095] refer to Figures 1-4 According to a first aspect embodiment of the present invention, the cleaning module 100 includes a mounting frame 4, a drive assembly 2, and a cleaning assembly 1. The drive assembly 2 is mounted on the mounting frame 4, and the cleaning assembly 1 is movably mounted on the mounting frame 4. The drive assembly 2 is connected to the cleaning assembly 1. The cleaning assembly 1 includes a cleaning component 11. The drive assembly 2 is configured to drive the cleaning component 11 to move between a first position and a second position. When the cleaning component 11 is in the first position, the cleaning component 11 contacts the working surface to clean the working surface. When the cleaning component 11 is in the second position, the cleaning component 11 disengages from the working surface.

[0096] Optionally, the cleaning component 1 is indirectly mounted on the mounting bracket 4.

[0097] For example, when the cleaning module 100 is applied to a cleaning device, when the cleaning device performs a cleaning task, the cleaning component 11 can be raised relative to the device body 5 to separate the cleaning part 113 from the working surface, so as to avoid the cleaning component 1 causing secondary pollution to the working surface or to avoid the cleaning component 1 colliding or interfering with the working surface at certain positions.

[0098] According to the cleaning module 100 of the present invention, by making the cleaning component 11 movable in a first position and a second position, the cleaning component 11 can be raised from the first position to the second position relative to the device body 5 during the cleaning process of the cleaning module 100 cleaning the working surface, so as to avoid the cleaning component 1 causing secondary pollution to the working surface, or to avoid collision interference between the cleaning component 11 and the protruding parts of the working surface.

[0099] refer to Figures 1-4According to some embodiments of the present invention, the drive component 2 is configured to drive the cleaning component 1 to rotate in a first direction so that the cleaning component 11 is in a first position, and to drive the cleaning component 1 to rotate in a second direction so that the cleaning component 11 is in a second position, the second direction being opposite to the first direction. In this way, the drive component 2 can simultaneously drive the rotation of the cleaning component 1 and the movement of the cleaning component 11 between the first and second positions. This eliminates the need for, or simplifies, the separate mechanisms for driving the movement of the cleaning component 11 between the first and second positions. For example, a separate drive motor 21 for driving the lifting and lowering of the cleaning component 11 can be omitted. This simplifies the structure of the cleaning module 100, reduces the layout difficulty of the cleaning equipment, and facilitates the miniaturization of the cleaning equipment.

[0100] According to some optional embodiments of the present invention, a lifting member 31 is further included, the cleaning member 11 is movably mounted on the lifting member 31, the lifting member 31 is movably mounted on the mounting bracket 4, the lifting member 31 is configured to stop rotating when the cleaning component 1 rotates in a first direction, so that the cleaning component 11 moves relative to the lifting member 31 to a first position, and the lifting member 31 and the cleaning component 1 rotate together when the cleaning component 11 is in the first position, and the lifting member 31 stops rotating when the cleaning component 1 rotates in a second direction, so that the cleaning component 11 moves relative to the lifting member 31 to a second position.

[0101] Optionally, the lifting member 31 extends in the vertical direction, and the lower end of the lifting member 31 is tractably connected to the cleaning member 11.

[0102] By providing a lifting member 31 and movably mounting the cleaning member 11 on the lifting member 31, the lifting member 31 provides support and guidance for the cleaning member 11. Thus, by changing the rotation state of the lifting member 31, the cleaning member 11 can move between a first position and a second position when the lifting member 31 stops rotating.

[0103] refer to Figures 1-4 According to some optional embodiments of the present invention, the cleaning module 100 further includes a constraint component 33, which is mounted on the mounting bracket 4. The constraint component 33 is used to constrain the rotation of the lifting member 31. The constraint of the lifting member 31 by the constraint component 33 includes preventing the lifting member 31 from rotating in a set direction or limiting the rotation of the lifting member 31 in a set direction by friction.

[0104] Optionally, the constraint assembly 33 includes a first constraint structure 331, which comprises two meshing parts. During the process of the cleaning component 11 moving downward relative to the lifting component 31 from the second position to the first position, the two parts of the first constraint structure 331 are in a meshing state, and the constraint assembly 33 can be used to prevent the lifting component 31 from rotating in the first direction. When the cleaning component 11 moves to the first position, the two parts of the first constraint structure 331 disengage, and the constraint assembly 33 releases the constraint on the lifting component 31 from rotating in the first direction.

[0105] Optionally, the constraint assembly 33 includes a first constraint structure 331, which comprises two parts that cooperate with each other by friction. During the process of the cleaning component 11 moving downward relative to the lifting component 31 from the second position to the first position, the friction between the two parts of the first constraint structure 331 allows the constraint assembly 33 to restrict the lifting component 31 from rotating in the first direction. When the cleaning component 11 moves to the first position, the drive assembly 2 can increase the drive so that the lifting component 31 can overcome the constraint of the friction between the two parts of the first constraint structure 331 on the rotation of the lifting component 31 in the first direction.

[0106] By setting the constraint component 33, the constraint component 33 effectively constrains the lifting component 31, so that the constraint component 33 can constrain the rotation of the lifting component 31, thereby enabling the lifting component 31 to stop rotating when the driving component 2 drives the cleaning component 1 to rotate in the first direction or in the second direction, so that the cleaning component 11 can move between the first position and the second position relative to the lifting component 31.

[0107] refer to Figures 1-4 According to some optional embodiments of the present invention, when the driving component 2 drives the cleaning component 1 to rotate in the first direction, the constraint component 33 is used to constrain the lifting component 31 to rotate in the first direction, so that the cleaning component 11 moves downward relative to the lifting component 31 from the second position to the first position.

[0108] When the cleaning component 11 is in the first position, the constraint component 33 releases the constraint on the lifting component 31 to rotate in the first direction, or the drive component 2 overcomes the constraint of the constraint component 33 on the lifting component 31 to rotate in the first direction. The drive component 2 drives the cleaning component 1 to rotate in the first direction and drives the lifting component 31 to rotate synchronously, so that the cleaning component 11 cleans the working surface.

[0109] When the driving component 2 drives the cleaning component 1 to rotate in the second direction, the constraint component 33 is used to constrain the lifting component 31 to rotate in the second direction, so that the cleaning component 11 moves upward relative to the lifting component 31 from the first position to the second position, and the second direction is opposite to the first direction.

[0110] For example, the drive assembly 2 includes a drive motor 21. In the initial state of the cleaning module 100, the cleaning assembly 1 is spaced apart from the work surface. The drive motor 21 rotates forward, driving the cleaning component 11 to rotate in a first direction. The constraint assembly 33 restricts the lifting component 31 from rotating in the first direction. The cleaning component 11 moves downward relative to the lifting component 31 from a second position to a first position, so that the cleaning component 11 contacts the work surface for cleaning. When the cleaning component 11 moves to the first position, the constraint assembly 33 releases the restriction on the lifting component 31 from rotating in the first direction, so that the drive assembly 2 drives the cleaning assembly 1 to rotate in the first direction and drives the lifting component 31 to rotate synchronously, so that the cleaning component 11 cleans the work surface. When the cleaning work is completed or a situation that may cause secondary pollution to the work surface is encountered, the drive motor 21 reverses, driving the cleaning assembly 1 to rotate in a second direction. The constraint assembly 33 restricts the lifting component 31 from rotating in the second direction, so that the cleaning component 11 moves upward relative to the lifting component 31 from the first position to the second position.

[0111] According to the present invention, the cleaning module 100, through the cooperation of the constraint component 33 and the lifting component 31, during the process of the driving component 2 driving the cleaning component 1 to rotate, the constraint component 33 constrains the lifting component 31 to rotate in the first direction or in the second direction, so that the cleaning component 11 of the cleaning component 1 can move relative to the lifting component 31 in the up and down direction between the first position and the second position. The arrangement of the constraint component 33 and the lifting component 31 is conducive to the stable movement of the cleaning component 11 of the cleaning module between the first position and the second position, thereby facilitating the stable operation of the cleaning module 100.

[0112] When the cleaning module 100 is applied to the cleaning equipment, the cleaning component 11 can still rotate under the driving action of the drive component 2 during the movement between the first position and the second position. For example, if there are some positions with different heights on the working surface, the cleaning component 11 can rotate during the up and down movement, which is conducive to effectively cleaning these positions. Thus, according to the working needs of the cleaning equipment, the cleaning module 100 can not only handle flat surfaces, but also some slightly undulating surfaces, which enhances the comprehensiveness and efficiency of the cleaning work.

[0113] Optionally, the cleaning component 1 may be a mopping component or a side brush component. Optionally, the cleaning component 11 includes a cleaning brush.

[0114] Optionally, constraint component 33 may include one or more constraint structures.

[0115] Optionally, the cleaning component 11 and the lifting component 31 are threadedly connected. When the driving component 2 drives the cleaning component 1 to rotate in the first direction and the constraint component 33 constrains the lifting component 31 to rotate in the first direction, the cleaning component 11 of the cleaning component 1 moves from the second position to the first position under the guidance of the thread.

[0116] refer to Figures 1-4 According to some embodiments of the present invention, the constraint component 33 includes a first constraint structure 331 and a second constraint structure 332. The first constraint structure 331 is used to constrain the lifting member 31 to rotate in a first direction. When the cleaning member 11 moves to a first position, the first constraint structure 331 releases the constraint on the lifting member 31 to rotate in the first direction, or the drive component 2 overcomes the constraint of the first constraint structure 331 on the lifting member 31 to rotate in the first direction. The second constraint structure 332 is used to constrain the lifting member 31 to rotate in a second direction.

[0117] For example, the drive assembly 2 includes a drive motor 21. In the initial state of the cleaning module 100, the cleaning component 11 is in a second position, and the cleaning assembly 1 is spaced apart from the working surface. When the drive motor 21 rotates forward, it drives the cleaning component 11 to rotate in the first direction. The first constraint structure 331 restricts the lifting component 31 from rotating in the first direction. The cleaning component 11 moves from the second position to the first position relative to the lifting component 31, so that the cleaning component 11 moves to a position in contact with the working surface to clean the working surface. When the cleaning component 11 moves to the first position, the constraint component 33 releases the restriction on the lifting component 31 from rotating in the first direction, so that the drive component 2 drives the cleaning component 1 to rotate in the first direction and drives the lifting component 31 to rotate synchronously, so that the cleaning component 11 cleans the working surface. When the cleaning work is completed or when a situation is encountered that may cause secondary pollution to the working surface, the drive motor 21 reverses, drives the cleaning component 1 to rotate in the second direction and drives the mating component 32 to rotate in the second direction. The second constraint structure 332 restricts the lifting component 31 from rotating in the second direction. The cleaning component 11 moves upward from the first position to the second position relative to the lifting component 31, so that the cleaning component 11 is raised to a position separated from the working surface.

[0118] By including a first constraint structure 331 and a second constraint structure 332 in the constraint assembly 33, and by using the first constraint structure 331 and the second constraint structure 332 to restrict the rotation of the lifting member 31 along a first direction and a second direction, respectively, the constraint effect of the constraint assembly 33 on the rotation of the lifting member 31 can be more precise. Through precise control, excessive load or unnecessary wear is avoided, improving the overall efficiency and durability of the cleaning module 100. Furthermore, this arrangement facilitates separate maintenance and replacement of the first constraint structure 331 and the second constraint structure 332.

[0119] refer to Figures 1-4 According to some optional embodiments of the present invention, the first constraint structure 331 and the second constraint structure 332 are arranged in the vertical direction.

[0120] According to some optional embodiments of the present invention, the first constraint structure 331 constrains the lifting member 31 to rotate in a first direction by means of frictional force on the lifting member 31, and the second constraint structure 332 constrains the lifting member 31 to rotate in the first direction by means of obstruction on the lifting member 31.

[0121] refer to Figures 1-4 According to some optional embodiments of the present invention, the first constraint structure 331 constrains the lifting member 31 to rotate in a first direction by applying frictional force to the lifting member 31, and the second constraint structure 332 constrains the lifting member 31 to rotate in a second direction by blocking the lifting member 31. By having the first constraint structure 331 constrain the lifting member 31 to rotate in the first direction by applying frictional force, the friction constraint structure is simple and easy to install. Furthermore, the first constraint structure 331 can absorb certain vibrations and impacts, helping to reduce system vibration and noise and improve operational stability. When the cleaning component 11 moves to the first position, only the constraint effect generated by the frictional force of the first constraint structure 331 needs to be overcome for the lifting member 31 to rotate together with the cleaning component 1, so that the cleaning component 1 can operate normally. This eliminates the need for other corresponding structures to ensure the cleaning component 1 can operate normally in the first position. By having the second constraint structure 332 constrain the lifting member 31 to rotate in the first direction by blocking the lifting member 31, the second constraint structure 332 provides stable constraint on the rotation of the lifting member 31 in the second direction.

[0122] refer to Figures 1-4 According to some optional embodiments of the present invention, the first constraint structure 331 is a damping structure, and the second constraint structure 332 is a one-way bearing sleeved on the outer periphery of the lifting member 31. The damping structure is flexibly configured and can be switched between states, so that the first constraint structure 331 can both satisfy the requirement of constraining the lifting member 31 to rotate in the first direction so that the cleaning member 11 can move from the second position to the first position, and when the cleaning member 11 is in the first position, the first constraint structure 331 can be released or the constraint of the first constraint structure 331 can be overcome so that the lifting member 31 can rotate together with the cleaning assembly 1 in the first direction; while the one-way bearing can stably constrain the rotation of the lifting member 31 in the second direction.

[0123] refer to Figures 1-4According to some optional embodiments of the present invention, the mounting frame 4 has a receiving cavity, for example, the mounting frame 4 is a box structure, at least part of the drive assembly 2 is disposed in the receiving cavity, the cleaning assembly 1 is located outside the mounting frame 4, the first constraint structure 331 is located above the second constraint structure 332, the lifting member 31 is rotatably disposed in the receiving cavity and the lower end of the lifting member 31 extends downward to the outside of the receiving cavity, the first constraint structure 331 includes a damping cover 3311, the upper end of the lifting member 31 is fitted with a damping ring 3312, the lifting member 31 and the damping ring 3312 are fixed relative to each other, the damping cover 3311 is fixed to the mounting frame 4, and the damping ring 3312 is detachably engaged with the damping cover 3311.

[0124] When the damping ring 3312 and the damping cover 3311 are engaged, the first constraint structure 331 is used to constrain the lifting member 31 to rotate in the first direction; when the damping ring 3312 and the damping cover 3311 are disengaged, the first constraint structure 331 releases the constraint on the lifting member 31 to rotate in the first direction.

[0125] The fact that at least a portion of the drive mechanism is located within the receiving cavity can include the following scenarios: For example, a portion of the drive mechanism is located within the receiving cavity, and the drive mechanism includes a drive motor 21 and a transmission component, wherein the transmission component is located within the receiving cavity, and the drive motor 21 is located outside the receiving cavity. Another example is that the entire drive mechanism is located within the receiving cavity, and the drive mechanism includes a drive motor 21 and a transmission component, both of which are located within the receiving cavity.

[0126] By including a damping ring 3312 fitted onto the upper end of the lifting member 31 and fixed relative to the lifting member 31, and a damping cover 3311 fixed on the mounting bracket 4, and by allowing the damping ring 3312 and the damping cover 3311 to be separably coupled, the rotation restriction of the lifting member 31 along the first direction by the first damping structure can be easily and flexibly activated or deactivated when needed, achieving refined management of the rotation control of the lifting member 31. Furthermore, the separability of the damping ring 3312 and the damping cover 3311 allows maintenance personnel to quickly inspect, clean, or replace either damping ring 3312 or damping cover 3311 if wear or adjustment is required, without the need for complex disassembly of the entire first damping structure. This simplifies maintenance work and reduces maintenance costs and time.

[0127] For example, during the process of the cleaning component 11 moving from the second position to the first position, the damping ring 3312 cooperates with the damping cover 3311 to restrict the rotation of the lifting component 31 in the first direction. For example, when the cleaning component 11 is in the first position, the damping ring 3312 and the damping cover 3311 separate to release the constraint of the first constraint structure 331 on the rotation of the lifting component 31 in the first direction.

[0128] refer to Figures 1-4According to some optional embodiments of the present invention, when the damping ring 3312 and the damping cover 3311 are engaged, the damping ring 3312 and the damping cover 3311 are engaged by friction.

[0129] Optionally, the upper surface of the damping ring 3312 is provided with a plurality of interlocking ribs distributed circumferentially along the damping ring 3312, and the lower surface of the damping cover 3311 is provided with a plurality of interlocking grooves distributed circumferentially along the damping ring 3312. The plurality of interlocking ribs are respectively accommodated in the interlocking grooves so that the damping ring 3312 and the damping cover 3311 are engaged.

[0130] By ensuring that the damping ring 3312 and the damping cover 3311 engage or are engaged by friction when they are in contact, a stable engagement relationship can be formed between them. This allows the first damping structure to effectively limit the rotation of the lifting member 31 in the first direction. Utilizing friction or direct engagement eliminates the need for additional complex mechanical devices, simplifying design, reducing costs, and minimizing potential failure points.

[0131] refer to Figures 1-4 According to some optional embodiments of the present invention, a mating groove 3313 is formed on the upper surface of the damping ring 3312, and a downwardly protruding mating protrusion 3314 is formed on the damping plastic cover. When the damping ring 3312 and the damping cover 3311 are engaged, the mating protrusion 3314 is accommodated within the mating groove 3313; when the damping ring 3312 and the damping cover 3311 are disengaged, the mating protrusion 3314 disengages from the mating groove 3313.

[0132] By forming a mating groove 3313 on the upper surface of the damping ring 3312 and a downwardly protruding mating protrusion 3314 on the damping plastic cover, the mating protrusion 3314 is accommodated within the mating groove 3313 when the damping ring 3312 and the damping cover 3311 are mated. This allows for precise alignment and a tight connection between the mating groove 3313 and the mating protrusion 3314 during the assembly of the cleaning module 100. This not only effectively transmits the required damping force but also prevents loosening or functional failure due to misalignment, improving the stability and reliability of the entire system. Furthermore, the mating relationship between the mating groove 3313 and the mating protrusion 3314 further enhances the damping effect of the first damping structure.

[0133] For example, the outer peripheral wall of the mating protrusion 3314 engages with the inner peripheral wall of the mating groove 3313 or is engaged by friction. For example, the upper surface of the mating protrusion 3314 engages with the bottom of the mating groove 3313 or is engaged by friction.

[0134] Optionally, the outer peripheral wall of the protrusion 3314 is provided with a plurality of interlocking ribs distributed circumferentially along the damping ring 3312, and the inner peripheral wall of the groove 3313 is provided with a plurality of interlocking grooves distributed circumferentially along the damping ring 3312. The plurality of interlocking ribs are respectively accommodated in the interlocking grooves so that the damping ring 3312 and the damping cover 3311 are engaged.

[0135] refer to Figures 1-4 According to some optional embodiments of the present invention, the damping cover 3311 is a plastic cover and the damping ring 3312 is a rubber ring. By making the damping cover 3311 a plastic cover and the damping ring 3312 a rubber ring, the rubber ring has a larger damping coefficient, thus enabling an effective damping effect to be formed between the damping ring 3312 and the damping cover 3311.

[0136] refer to Figures 1-4 According to some optional embodiments of the present invention, the second constraint structure 332 is sleeved on the outer periphery of the lifting member 31, and the second constraint structure 332 is a one-way bearing. By sleeved on the outer periphery of the lifting member 31, the assembly relationship between the second damping structure and the lifting member 31 is simple and easy to install; and by making the second damping structure a one-way bearing, the one-way bearing can provide a stable and effective restriction on the rotation of the lifting member 31 in the second direction.

[0137] refer to Figures 1-4 According to some optional embodiments of the present invention, when the cleaning component 11 is in the first position and the driving component 2 drives the cleaning component 11 to rotate in the first direction, the lifting component 31 can move relative to the cleaning component 11 to disengage the damping ring 3312 from the damping cover 3311. After the cleaning component 11 moves to the second position, the cleaning component 11 rotates in the first direction. When it is not necessary to strictly constrain the rotation of the lifting component 31, the damping is automatically released by the downward movement of the lifting component 31, which can reduce unnecessary load, thereby reducing the workload of the driving mechanism and saving energy consumption. At the same time, it reduces the continuous wear on the damping component and extends the service life of the first damping structure.

[0138] Optionally, the cleaning component 11 and the lifting component 31 are threaded together. After the cleaning component 11 moves to the second position, the lifting component 31 can move automatically downward under the guidance of the threaded connection, thereby disengaging the damping ring 3312 from the damping cover 3311. This method improves the degree of automation and ease of use.

[0139] refer to Figures 1-4According to some optional embodiments of the present invention, the cleaning assembly 1 includes a cleaning housing 12, and the cleaning component includes a mounting base and a cleaning element. The cleaning element includes a connecting arm 112 and a cleaning section. The mounting base 111 is located inside the cleaning housing 12, and the cleaning section 113 is located outside the cleaning housing 12. The cleaning section 113 is used to contact the working surface to clean the working surface. The mounting base 111 and the cleaning section 113 are connected by the connecting arm 112. A through hole 123 for the connecting arm 112 to pass through is formed on the outer peripheral wall of the cleaning housing 12. The connecting arm 112 is a flexible arm. The lower end of the lifting member 31 is tractably connected to the mounting base 111. The mounting base 111 is movable relative to the lifting member 31 in the vertical direction between a first height position and a second height position, so that the mounting base 111 can float in the vertical direction within the cleaning housing 12, and so that the cleaning section 113 can move in the vertical direction between the first position and the second position.

[0140] When the mounting base 111 is in the first height position, the cleaning part 113 is in the second position; when the mounting base 111 is in the second height position, the cleaning part 113 is in the first position. During the vertical movement of the mounting base 111 relative to the lifting member 31 between the first and second height positions, the cleaning part 11 moves vertically between the second and first positions relative to the lifting member 31. For example, if the first height position is below the second height position, during the upward movement of the cleaning part 113 from the first height position to the second height position, the cleaning part 113 moves from the second position to the first position; similarly, during the downward movement of the cleaning part 113 from the second height position to the first height position, the cleaning part 11 moves from the first position to the second position.

[0141] When the cleaning part 113 moves upward to the second position and the drive assembly 2 stops working, the mounting base 111 moves upward relative to the cleaning housing 12 under the elastic force of the connecting arm 112, so as to drive the lifting part 31 to move upward, so that the damping ring 3312 and the damping cover 3311 cooperate.

[0142] By positioning the mounting base 111 at the second height position and when the drive mechanism stops working, the mounting base 111 moves upward relative to the cleaning housing 12 under the elastic force of the connecting arm 112, thereby driving the lifting component 31 to move upward so that the damping ring 3312 engages with the damping cover 3311. This arrangement allows the engagement between the damping ring 3312 and the damping cover 3311 to automatically recover after the mounting base 111 moves to the second height position and the cleaning component 11 moves to a state separated from the working surface. This ensures that when the cleaning part 113 needs to move to the first position again, the first damping structure can effectively constrain the rotation of the lifting component 31 along the first direction, allowing the cleaning module 100 to operate and work normally in the future, thus improving the reliability and consistency of the cleaning module 100.

[0143] For example, the drive mechanism includes a drive motor 21. In the initial state of the cleaning module 100, the mounting base 111 is at a first height position, the cleaning part 113 is at a second position, and the cleaning component 1 is spaced apart from the working surface. When the drive motor 21 rotates forward, it drives the cleaning component 11 to rotate in a first direction and causes the mounting base 111 to rotate in the first direction. The damping ring 3312 and the damping cover 3311 cooperate to constrain the lifting member 31 to rotate in the first direction. The mounting base 111 moves upward relative to the lifting member 31 from the first height position to the first height position, so that the cleaning component 11 moves to a position in contact with the working surface for cleaning. When the mounting base 111 is at the first height position, the cleaning module 100 switches from the first state to the second state, the lifting member 31 can move relative to the mounting base 111, and the damping ring 3312 and the damping cover 3311 disengage. The constraint on the lifting component 31 rotating in the first direction is released; the drive motor 21 reverses, drives the cleaning component 1 to rotate in the second direction and drives the mounting base 111 to rotate in the second direction. The one-way bearing constrains the lifting component 31 to rotate in the second direction. The mounting base 111 moves downward relative to the lifting component 31 from the first height position to the second height position, so that the cleaning component 11 is raised to a position separated from the working surface. Under the elastic force of the connecting arm 112, the mounting base 111 moves upward relative to the cleaning housing 12, so that the lifting component 31 moves upward, so that the damping ring 3312 and the damping cover 3311 cooperate.

[0144] refer to Figures 1-4 According to some optional embodiments of the present invention, the cleaning module 100 further includes a mating member 32. A mating section 311 is formed at the lower end of the lifting member 31. The mating member 32 is fixed to the cleaning component 11 and threadedly connected to the mating section 311. The mating member 32 is movable relative to the lifting member 31 in the vertical direction between a first height position and a second height position. By including the mating member 32 fixed to the cleaning component 11 and threadedly connected to the mating section 311 of the screw in the cleaning module 100, the thread can guide the mating member 32. When the lifting member 31 is constrained by the constraint assembly 33, the mating member 32 can drive the cleaning component 11 to move vertically between the first height position and the second height position under its guiding action.

[0145] refer to Figures 1-4 According to some optional embodiments of the present invention, a threaded hole 321 is formed in the mating member 32, and an external threaded portion 3111 with threaded engagement is formed on the outer peripheral wall of the mating section 311. By forming a threaded hole 321 in the mating member 32 and an external threaded portion 3111 with threaded engagement on the outer peripheral wall of the mating section 311, the assembly relationship between the mating member 32 and the mating section 311 is simple.

[0146] Optionally, the first height position is located above the second height position. When the mating part 32 is in the second height position, the cleaning part 11 contacts the working surface to clean the working surface. When the mating part 32 moves upward from the second height position to the first height position, the cleaning part 11 is raised to separate the cleaning part 11 from the working surface. When the mating part 32 moves again from the first height position to the second height position, the cleaning part 11 moves to contact the working surface to clean the working surface.

[0147] Optionally, the first height position is located above the second height position. When the mating part 32 is in the first height position, the cleaning part 11 contacts the working surface to clean the working surface. When the mating part 32 moves downward from the first height position to the second height position, the cleaning part 11 is raised upward to separate the cleaning part 11 from the working surface. When the mating part 32 moves back to the first height position from the second height position, the cleaning part 11 moves to contact the working surface to clean the working surface.

[0148] Optionally, the mating part 32 and the lifting part 31 are formed as metal parts.

[0149] For example, the drive assembly 2 includes a drive motor 21. In the initial state of the cleaning module 100, the mating part 32 is at a second height position, and the cleaning assembly 1 is spaced apart from the work surface. When the drive motor 21 rotates forward, it drives the cleaning component 11 to rotate in a first direction and causes the mating part 32 to rotate in the first direction. The constraint assembly 33 restricts the lifting part 31 from rotating in the first direction. The mating part 32 moves upward relative to the lifting part 31 from the second height position to the first height position, so that the cleaning component 11 moves to a position in contact with the work surface for cleaning. When the mating part 32 is at the first height position, the cleaning module 100 switches from the first state to the second state, and the constraint assembly 33 releases the restriction on the lifting part 31 from rotating in the first direction. When the drive motor 21 rotates in reverse, it drives the cleaning assembly 1 to rotate in the second direction and causes the mating part 32 to rotate in the second direction. The constraint assembly 33 restricts the lifting part 31 from rotating in the second direction. The mating part 32 moves downward relative to the lifting part 31 from the first height position to the second height position, so that the cleaning component 11 is raised to a position spaced apart from the work surface.

[0150] refer to Figures 1-4 According to some optional embodiments of the present invention, the cleaning assembly 1 includes a cleaning housing 12, and the cleaning component 11 includes a connected mounting base 111 and a cleaning element. The cleaning element includes a connecting arm 112 and a cleaning part 113. The mounting base 111 is located inside the cleaning housing 12, which enhances the overall stability and durability: the mounting base 111 is fixed inside the cleaning housing 12, providing a solid foundation for the cleaning part 113, ensuring the stability of the assembly even during high-speed rotation or heavy cleaning operations, reducing vibration, and improving the overall durability and service life.

[0151] The cleaning part 113 is located outside the cleaning housing 12. The mounting base 111 is connected to the cleaning part 113 by a connecting arm 112. A through hole 123 for the connecting arm 112 to pass through is formed on the outer peripheral wall of the cleaning housing 12. The cleaning housing 12 is designed with a through hole 123 for the connecting arm 112 to pass through. In this way, while ensuring the movement of the cleaning part 113, a large opening is avoided on the cleaning housing 12, the structural strength of the housing is maintained, and the design complexity and manufacturing cost are reduced.

[0152] The mating part 32 is fixed to the mounting base 111. The cleaning component 11 can move up and down relative to the cleaning housing 12. The drive mechanism is connected to the cleaning housing 12 to drive the cleaning component 1 to rotate. The drive mechanism is directly connected to the cleaning housing 12, which can transmit power more directly and efficiently, enabling the cleaning component 1 to complete the rotational movement more quickly and accurately, thus improving cleaning efficiency. In addition, this integration method also helps to optimize the space utilization of the entire system and simplify the layout of the drive system.

[0153] By including a connected mounting base 111, a connecting arm 112, and a cleaning part 113 in the cleaning component 11, the cleaning part 113 is located outside the cleaning housing 12 and is connected to the mounting base 111 via the connecting arm 112. This arrangement makes it easy for the cleaning part 113 to clean the work surface, and the setting of the connecting arm 112 allows the cleaning part 113 to have a certain range of motion, thus enhancing the flexibility of cleaning.

[0154] refer to Figures 1-4 According to some optional embodiments of the present invention, there are multiple cleaning components 11, which are arranged at intervals along the circumference of the cleaning housing 12. By having multiple cleaning components 11 and arranging them at intervals along the circumference of the cleaning housing 12, it is beneficial to improve the cleaning effect of the cleaning components 11.

[0155] refer to Figures 1-4 According to some optional embodiments of the present invention, the connecting arm 112 is a flexible arm, and the mounting base 111 is floatable in the vertical direction, so that the cleaning part 113 can move in the vertical direction. By making the connecting arm 112 a flexible arm, the cleaning part 113 can better adapt to different working surfaces, and even uneven or complex geometric surfaces can achieve closer contact, improving the cleaning effect. Moreover, compared with a rigid structure, the flexible arm can respond more gently when in contact with the working surface. The design of the flexible arm can bend moderately when encountering obstacles to reduce direct impact, which can avoid or reduce the occurrence of breakage or damage to the cleaning part 11 during use. At the same time, the floating mounting base 111 can reduce wear caused by hard impact or friction, extending the service life of the equipment.

[0156] For example, when the first height position is above the second height position, the cleaning component 11 contacts the working surface to clean the working surface when the mating component 32 is in the first height position; when the mating component 32 moves down from the first height position to the second height position, the flexible arm undergoes elastic deformation, and the cleaning component 11 is raised to separate the cleaning component 11 from the working surface; when the mating component 32 moves back from the second height position to the first height position, the flexible arm gradually returns from the elastic deformation state, and the cleaning component 11 moves to contact the working surface to clean the working surface.

[0157] refer to Figures 1-4 According to some optional embodiments of the present invention, the cleaning housing 12 includes a detachably connected upper housing 121 and a lower housing 122, with a through hole 123 defined between the upper housing 121 and the lower housing 122. By including the detachably connected upper housing and lower housing 122 in the cleaning housing 12, it is convenient to install the cleaning component 11 into the cleaning housing 12, thereby facilitating the assembly of the cleaning module 100.

[0158] refer to Figures 1-4 Optionally, the upper housing 121 is also formed with a clearance notch for avoiding the cleaning part 113. The clearance notch is opposite to and connected to the through hole 123 in the vertical direction.

[0159] refer to Figures 1-4 Optionally, the flexible arm includes a first flexible segment, a second flexible segment and a third flexible segment connected in sequence. The first flexible segment is located inside the cleaning housing 12 and connected to the mounting base 111, the second flexible segment passes through the through hole 123, and the third flexible segment is located outside the cleaning housing 12.

[0160] The mating part 32 is at the first height position, the first flexible section is in an undeformed state, the second flexible section is spaced apart from the lower shell 122 of the flexible section, the third flexible section is in an undeformed state, and the cleaning part 113 is in contact with the working surface.

[0161] The mating part 32 is at the second height position. The mating part 32 drives the first flexible section to bend downward through the mounting base 111. The second flexible section is supported at the through hole 123 of the lower housing 122. The third flexible section is warped upward. The cleaning part 113 is separated from the working surface.

[0162] refer to Figures 1-4According to some optional embodiments of the present invention, the driving mechanism includes a drive motor 21 and a first transmission member 22. The first transmission member 22 is loosely fitted around the outer periphery of the lifting member 31, and there is no transmission relationship between the first transmission member 22 and the lifting member 31. The first transmission member 22 is located above the cleaning assembly 1 and is connected to the cleaning housing 12. The drive motor 21 is connected to the first transmission member 22 to drive the first transmission member 22 to rotate. By connecting the first transmission member 22 to the cleaning housing 12, the first transmission member 22 can stably and efficiently transmit the driving force from the drive motor 21 to the cleaning housing 12, thereby stably driving the cleaning assembly 1 to rotate.

[0163] refer to Figures 1-4 According to some optional embodiments of the present invention, the first transmission component 22 is detachably connected to the cleaning housing 12. By making the first transmission component detachably connected to the cleaning housing 12, it is convenient to inspect, maintain, and replace the first transmission component 22 and the cleaning housing 12 separately.

[0164] Optionally, the first transmission member 22 includes a gear portion and a fixing portion located at the lower end of the gear portion. The fixing portion is detachably connected to the cleaning housing 12, and the fixing portion and the gear portion are detachably connected.

[0165] refer to Figures 1-4 According to some optional embodiments of the present invention, one of the first transmission member 22 and the cleaning housing 12 has a locking hole 222 and the other has a locking buckle 124, which engages with the locking hole 222. This engagement of the locking buckle 124 with the locking hole 222 simplifies assembly and ensures a stable connection, facilitating stable power transmission between the first transmission member 22 and the cleaning housing 12.

[0166] For example, a buckle 124 is formed on the first transmission member 22, and a locking hole 222 is formed on the cleaning housing 12. The buckle 124 engages with the locking hole 222 to enable a transmission connection between the first transmission member 22 and the cleaning housing 12. As another example, a locking hole 222 is formed on the first transmission member 22, and a buckle 124 is formed on the cleaning housing 12. The buckle 124 engages with the locking hole 222 to enable a transmission connection between the first transmission member 22 and the cleaning housing 12.

[0167] refer to Figures 1-4According to some optional embodiments of the present invention, the cleaning housing 12 is provided with a plurality of buckles 124 arranged at intervals along the circumference of the cleaning housing 12. The first transmission member 22 is formed with mounting holes 221, and the plurality of buckles 124 are located within the mounting holes 221. The inner peripheral wall of the mounting holes 221 is formed with a plurality of locking holes 222 arranged at intervals along the circumference of the mounting holes 221. The number of locking holes 222 is the same as the number of buckles 124 and they correspond one-to-one. By forming mounting holes 221 on the first transmission member 22, during the assembly process of the cleaning module 100, the operator can align the cleaning housing 12 with the first transmission member 22 by referring to the position of the mounting holes 221, and then engage the buckles 124 with the locking holes 222, which simplifies the assembly process and also facilitates daily maintenance or replacement of the cleaning housing 12. The circumferentially spaced arrangement of the plurality of buckles 124 and locking holes 222 can further improve the connection stability and reliability between the cleaning housing 12 and the first transmission member 22. This multi-point connection and fixing method can also distribute the force evenly, maintaining good stability even in high-speed or heavy-load cleaning operations, reducing the risk of loosening or displacement, and ensuring the efficiency and precision of cleaning operations.

[0168] refer to Figures 1-4 According to some optional embodiments of the present invention, the drive mechanism further includes a gear transmission mechanism, and the drive motor 21 and the first transmission member 22 are connected by the gear transmission mechanism. By including a gear transmission mechanism in the drive mechanism, the gear transmission mechanism can transmit the power of the drive motor 21 to the first transmission member 22, and the gear transmission method has higher stability.

[0169] refer to Figures 1-4 According to a second aspect of the present invention, the cleaning device includes: a device body 5 and the cleaning module 100 described above, wherein the cleaning module 100 is installed on the device body 5.

[0170] Optionally, the cleaning device also includes a control unit, a positioning structure 61, and a position detection structure 62. The positioning structure 61 is located on the cleaning component 1, and the position detection structure 62 is located on the device body 5. When the cleaning component 1 is in the second position and the positioning structure 61 and the position detection structure 62 are in contact in the rotation direction of the cleaning component 1, the cleaning component 1 is positioned at a preset angle position.

[0171] The drive assembly 2 includes a drive motor 21 for driving the cleaning assembly 1 to rotate. The control unit is electrically connected to the drive motor 21 to control the drive motor 21. The control unit is used to control the drive motor 21 to turn off when the cleaning assembly 1 is positioned at a preset angle.

[0172] The cleaning component 1 is located below the device body 5, and the position detection structure 62 is located on the bottom surface of the device body 5.

[0173] For example, when the cleaning work is completed or when a situation arises that may cause secondary pollution to the work surface, the drive motor 21 reverses and drives the cleaning component 1 to rotate in the second direction, so that the cleaning component 1 moves from the first position to the second position relative to the lifting component 31. When the cleaning component 1 moves to the second position and the positioning structure 61 and the position detection structure 62 contact in the second direction, the cleaning component 1 is at a preset angle position. At this time, the control unit controls the drive motor 21 to turn off.

[0174] By setting a position positioning structure 6 including a positioning structure 61 and a position detection structure 62, the cleaning component 1 can be positioned at a preset angle position through the cooperation of the positioning structure 61 and the position detection structure 62. This can prevent the cleaning component 1 in the second position from staying in an inappropriate position, which would cause the cleaning component 1 to affect the normal operation of the other structures on the cleaning equipment.

[0175] Optionally, the cleaning equipment also includes a detection unit, which is used to directly or indirectly detect whether the positioning structure 61 and the position detection structure 62 are in contact, and the control unit is used to control the drive motor 21 to shut down when the detection unit detects that the positioning structure 61 and the position detection structure 62 are in contact.

[0176] The detection unit detects the current of the drive motor 21 to indirectly detect whether the positioning structure 61 and the position detection structure 62 are in contact. Specifically, when the detection unit detects a sudden increase in the current of the drive motor 21, the positioning structure 61 and the position detection structure 62 come into contact. By using the detection unit to detect the current of the drive motor 21 to indirectly detect whether the positioning structure 61 and the position detection structure 62 are in contact, the detection unit can promptly detect changes in the motor current and stop the motor in time when the positioning structure 61 and the position detection structure 62 come into contact, avoiding overload or damage to the motor. When the motor load increases, causing a sudden change in current, the control system can react quickly, reducing unnecessary energy waste. By reducing unnecessary motor operating time and load, the service life of the motor and the entire cleaning equipment can be extended.

[0177] Optionally, at least one of the positioning structure 61 and the position detection structure 62 is a flexible or elastic structure. For example, the positioning structure 61 or the position detection structure 62 may be a flexible or elastic structure; for example, both the positioning structure 61 and the position detection structure 62 may be flexible or elastic structures. For example, the positioning structure 61 may be made of felt, and the position detection structure 62 may be made of rubber. By making at least one of the positioning structure 61 and the position detection structure 62 a flexible or elastic structure, the first positioning mechanism and the position detection structure 62 will make flexible contact when they come into contact. The flexible or elastic structure can absorb impact forces and prevent damage from contact collisions, etc.

[0178] Optionally, the positioning structure 61 includes a plurality of positioning protrusions 611 spaced apart circumferentially along the cleaning component 1, and the position detection structure 62 includes a plurality of position detection protrusions 621 spaced apart circumferentially along the cleaning component 1, with each of the position detection protrusions 621 corresponding to one of the positioning protrusions 611. For example, the position detection protrusions 621 are formed on the connecting arm 112 of the cleaning component 11.

[0179] By including multiple positioning protrusions 611 spaced circumferentially along the cleaning component 1 in the positioning structure 61, and multiple position detection protrusions 621 spaced circumferentially along the cleaning component 1 in the position detection structure 62, the cooperation between the multiple positioning protrusions 611 and the multiple position detection protrusions 621 is beneficial to further improve the positioning effect of the positioning structure 6, so that the cleaning component 1 can be stably positioned at a preset angle position, thereby effectively avoiding the cleaning component 1 from causing adverse effects on the normal operation of other structures of the cleaning equipment.

[0180] refer to Figures 1-4 According to some embodiments of the present invention, the cleaning module 100 is located adjacent to the outer periphery of the device body 5. Optionally, the cleaning module 100 may be a side brush module. By placing the cleaning module 100 adjacent to the outer periphery of the device body 5, it is beneficial to expand the cleaning range of the cleaning module 100.

[0181] According to some optional embodiments of the present invention, there are multiple cleaning modules 100, which are arranged at intervals along the circumference of the device body 5. By having multiple cleaning modules 100, and the multiple first cleaning modules being arranged at intervals along the circumference of the device body 5, it is beneficial to increase the cleaning area of ​​the first cleaning modules, thereby further improving the cleaning effect of the cleaning equipment.

[0182] According to some optional embodiments of the present invention, the cleaning device includes a first cleaning module and a second cleaning module 100. The second cleaning module 100 is installed on the device body 5. The second cleaning module 100 is the main cleaning module 100, and the first cleaning module is an auxiliary cleaning module 100 according to the first aspect embodiment of the present invention. For example, the second cleaning module 100 is a roller brush assembly, and the first cleaning module is a side brush assembly. The side brush assembly is beneficial to improving the cleaning degree of the cleaning device on corners, wall bases, and other locations. By including a main cleaning module 100 and an auxiliary cleaning module 100 in the cleaning device, the cleaning effect of the cleaning device is improved.

[0183] For example, during the operation of the cleaning equipment, the cleaning component 11 of the auxiliary cleaning module 100 is initially separated from the work surface. When the cleaning equipment needs the auxiliary cleaning device to clean the work surface, the drive motor 21 rotates forward, driving the cleaning component 11 to rotate in the first direction and causing the mating component 32 to rotate in the first direction. The damping ring 3312 and the damping cover 3311 of the first damping structure cooperate, and the first damping structure constrains the lifting component 31 to rotate in the first direction. The mating component 32 moves upward relative to the lifting component 31 from the second height position to the first height position, so that the cleaning part 113 moves downward from the second position to the first position in contact with the work surface for cleaning. When the mating component 32 is at the first height position, the cleaning part 113 is in the first position. The lifting component 31 moves downward to separate the damping ring 3312 and the damping cover 3311. The first damping structure releases the constraint on the lifting component 31 to rotate in the first direction. The mating component 32 drives the lifting component 31 to rotate together, and the cleaning part 113 cleans the working surface. When the auxiliary cleaning module 100 completes the cleaning operation or encounters a situation where the auxiliary cleaning module 100 may cause secondary pollution to the working surface, the drive motor 21 reverses. The drive motor 21 drives the cleaning component 1 to rotate in the second direction and drives the mating component 32 to rotate in the second direction. The second damping structure constrains the lifting component 31 to rotate in the second direction. The mating component 32 moves downward relative to the lifting component 31 from the first height position to the second height position, so that the cleaning part 113 is raised from the first position to the second position separated from the working surface.

[0184] According to some optional embodiments of the present invention, the first cleaning module and the second cleaning module 100 are arranged at intervals in the front-to-back direction. By arranging the auxiliary cleaning module 100 and the main cleaning module 100 at intervals in the front-to-back direction, interference between the main cleaning module 100 and the auxiliary cleaning module 100 when cleaning the work surface can be avoided.

[0185] According to a third aspect of the present invention, the cleaning system includes: the cleaning device and the cleaning base station described above, wherein the cleaning device is adapted to cooperate with the cleaning base station, the cleaning base station is used to clean the cleaning device, and the cleaning base station can also be used to charge the cleaning device.

[0186] Next, we will refer to Figures 1-4 The cleaning module 100 of some embodiments of the present invention will be described.

[0187] refer to Figures 1-4 In this embodiment, the cleaning module 100 is applied to a cleaning device, such as a robotic vacuum cleaner. The cleaning module 100 includes a cleaning component 1, a drive mechanism, and a lifting component 3. The drive mechanism is connected to the cleaning component 1 to drive the rotation of the component 2, and the lifting component 3 is connected to the cleaning component 1 to control the cleaning component 1 to move in the up and down direction.

[0188] The cleaning assembly 1 includes a cleaning housing 12 and cleaning components. Each cleaning component includes a mounting base 111 and a cleaning component 11. The cleaning component 11 includes a connected connecting arm 112 and a cleaning brush. The mounting base 111 is located inside the cleaning housing 12, and the cleaning brush is located outside the cleaning housing 12. The mounting base 111 and the cleaning brush are connected via the connecting arm 112. A through hole 123 is formed on the outer peripheral wall of the cleaning housing 12 for the connecting arm 112 to pass through. A mating member 32 is fixed to the mounting base 111. The cleaning component 11 is movable up and down relative to the cleaning housing 12. The cleaning housing 12 includes a detachably connected upper housing 121 and a lower housing 122, with the through hole 123 defined between the upper housing 121 and the lower housing 122. Multiple cleaning components 11 are arranged at intervals along the circumference of the cleaning housing 12. The connecting arm 112 is a flexible arm, and the mounting base 111 is floatable in the up-down direction, allowing the cleaning brush to move in the up-down direction.

[0189] The drive mechanism includes a drive motor 21, a first transmission component 22, and a gear transmission mechanism. The drive motor 21 and the first transmission component 22 are connected by the gear transmission mechanism. The first transmission component 22 is located above the cleaning assembly 1 and is detachably connected to the cleaning housing 12. The drive motor 21 is connected to the first transmission component 22 to drive the first transmission component 22 to rotate.

[0190] The cleaning housing 12 is provided with a plurality of buckles 124 arranged at intervals along the circumference of the cleaning housing 12. The first transmission member 22 is provided with a mounting hole 221. The plurality of buckles 124 are located in the mounting hole 221. The inner peripheral wall of the mounting hole 221 is provided with a plurality of locking holes 222 arranged at intervals along the circumference of the mounting hole 221. The number of locking holes 222 is the same as the number of buckles 124 and they correspond one-to-one.

[0191] The lifting assembly 3 includes a lifting member 31, a mating member 32, and a damping assembly. The lifting member 31 extends vertically, and a mating section 311 is formed at the lower end of the lifting member 31. The mating member 32 is fixed to the cleaning member 11 and threadedly connected to the mating section 311. The first transmission member 22 is loosely fitted on the outer periphery of the lifting member 31 and located above the mating member 32. A threaded hole 321 is formed in the mating member 32, and an external threaded portion 3111 with threaded engagement is formed on the outer periphery of the mating section 311.

[0192] The mating component 32 is movable relative to the lifting component 31 in the vertical direction between a first height position and a second height position, so that the cleaning component 11 is movable in the vertical direction, and the cleaning part 113 is movable relative to the lifting component 31 in the vertical direction between the second position and the first position. When the cleaning part 113 moves downward to the first position, the constraint component 33 releases the constraint on the lifting component 31 to rotate in the first direction, or the drive component 2 overcomes the constraint on the lifting component 31 to rotate in the first direction, and the drive component 2 drives the cleaning component 1 to rotate in the first direction and drives the lifting component 31 to rotate synchronously, so that the cleaning part 113 cleans the working surface.

[0193] During the process of the mating component 32 moving from the second height position to the first height position relative to the lifting component 31, the driving mechanism drives the mating component 32 to rotate along the first direction, the constraint component 33 is used to constrain the lifting component 31 to rotate along the first direction, and the cleaning part 113 moves from the second position to the first position; during the process of the mating component 32 moving from the first height position to the second height position relative to the lifting component 31, the driving mechanism drives the mating component 32 to rotate along the second direction, the constraint component 33 is used to constrain the lifting component 31 to rotate along the second direction, and the cleaning part 113 moves from the first position to the second position, the second direction being opposite to the first direction;

[0194] Specifically, the damping assembly includes a first damping structure and a second damping structure arranged in the vertical direction. The first constraint structure 331 is used to constrain the lifting member 31 to rotate in a first direction. When the cleaning section 113 moves downward to a first position, the first constraint structure 331 releases the constraint on the lifting member 31's rotation in the first direction, or the drive assembly 2 overcomes the constraint of the first constraint structure 331 on the lifting member 31's rotation in the first direction. The second constraint structure 332 is used to constrain the lifting member 31 to rotate in a second direction.

[0195] The cleaning module 100 also includes a mounting frame 4 with a receiving cavity. A first transmission component 22, a lifting component 31, and a damping assembly are disposed within the receiving cavity. The cleaning assembly 1 is located below the mounting frame 4, and the first damping structure is located above the second damping structure. The lifting component 31 is rotatably disposed within the receiving cavity, with its lower end extending downwards beyond the cavity. The first damping structure includes a damping cover 3311 and a damping ring 3312. The damping ring 3312 is sleeved on the upper end of the lifting component 31 and fixed relative to it. The damping cover 3311 is fixed to the mounting frame 4. The damping ring 3312 and the damping cover 3311 are separably coupled. When the damping ring 3312 and the damping cover 3311 are coupled, they engage or are coupled by friction. A mating groove 3313 is formed on the upper surface of the damping ring, and a downwardly protruding mating protrusion 3314 is formed on the damping plastic cover. The damping cover 3311 is a plastic cover, and the damping ring 3312 is a rubber ring.

[0196] When the damping ring 3312 and the damping cover 3311 are engaged, the engaging protrusion 3314 is accommodated in the engaging groove 3313, and the first damping structure is used to constrain the lifting member 31 to rotate in the first direction; when the damping ring 3312 and the damping cover 3311 are disengaged, the engaging protrusion 3314 is disengaged from the engaging groove 3313, and the first damping structure releases the constraint on the lifting member 31 to rotate in the first direction.

[0197] When the mating part 32 is at the first height position and the drive mechanism drives the mating part 32 to rotate in the first direction, the lifting part 31 can move downward relative to the mating part 32, so that the damping ring 3312 disengages from the damping cover 3311. When the mating part 32 is at the second height position and the drive mechanism stops working, the mounting base 111 moves upward relative to the cleaning housing 12 under the elastic force of the connecting arm 112, so as to drive the lifting part 31 to move upward, so that the damping ring 3312 engages with the damping cover 3311.

[0198] The second damping structure is sleeved on the outer periphery of the lifting component 31, and the second damping structure is a one-way bearing.

[0199] For example, the drive assembly 2 includes a drive motor 21. In the initial state of the cleaning module 100, the cleaning part 113 is in the second position, and the cleaning assembly 1 is spaced apart from the working surface. When the drive motor 21 rotates forward, it drives the cleaning component 11 to rotate in the first direction. The first constraint structure 331 restricts the lifting component 31 from rotating in the first direction. The cleaning part 113 moves downward from the second position to the first position relative to the lifting component 31, so that the cleaning component 11 moves to a position in contact with the working surface to clean the working surface. When the cleaning part 113 moves to the first position, the constraint component 33 releases the restriction on the lifting component 31 from rotating in the first direction, so that the drive component 2 drives the cleaning component 1 to rotate in the first direction and drives the lifting component 31 to rotate synchronously, so that the cleaning part 113 cleans the working surface. When the cleaning work is completed or when a situation is encountered that may cause secondary pollution to the working surface, the drive motor 21 reverses, drives the cleaning component 1 to rotate in the second direction and drives the mating component 32 to rotate in the second direction. The second constraint structure 332 restricts the lifting component 31 from rotating in the second direction, so that the cleaning component 11 is raised to a position separated from the working surface.

[0200] refer to Figures 5-9 According to a fourth aspect of the present invention, the cleaning device includes: a device body 5, a first cleaning module, a position detection structure 62, and a control unit, wherein the first cleaning module and the control unit are both disposed on the device body 5.

[0201] The first cleaning module is installed on the device body 5 and includes a cleaning component 1 and a drive component 2. For example, the cleaning component 1 includes a cleaning part 11, which is used to contact the working surface to clean the working surface. The drive component 2 is connected to the cleaning component 1 and is used to drive the cleaning component 1 to rotate and to drive the cleaning component 1 to move between a first position and a second position in the up-down direction. The first position is located below the second position.

[0202] Optionally, the first cleaning module is the cleaning module 100 in the first aspect embodiment of the present invention.

[0203] The position detection structure 62 is located on the device body 5. When the cleaning component 1 and the position detection structure 62 come into contact in the rotation direction of the cleaning component 1, the cleaning component 1 is positioned at a preset angle.

[0204] Optionally, the cleaning component 1 and the position detection structure 62 may be in direct contact, or they may be in indirect contact.

[0205] The drive assembly 2 includes a drive motor 21 for driving the cleaning assembly 1 to rotate. The control unit is electrically connected to the drive motor 21 to control the drive motor 21. The control unit is used to control the drive motor 21 to turn off when the cleaning assembly 1 is positioned at a preset angle.

[0206] By setting the position detection structure 62, the cleaning component 1 can be positioned at a preset angle position through the contact and cooperation between the cleaning component 1 and the position detection structure 62. This can prevent the cleaning component 1, which is in the second position, from staying in an inappropriate position, which would cause the cleaning component 1 to affect the normal operation of the other structures on the cleaning equipment.

[0207] refer to Figures 5-9 According to some embodiments of the present invention, the cleaning device includes a detection unit for directly or indirectly detecting whether the cleaning component 1 is in contact with the position detection structure 62, and a control unit for controlling the drive motor 21 to shut down when the detection unit detects that the cleaning component 1 is in contact with the position detection structure 62.

[0208] Optionally, the detection unit can be a pressure sensor or the like, which can be used to directly detect whether the cleaning component 1 and the position detection structure 62 are in contact.

[0209] Optionally, the detection unit is used to indirectly detect whether the cleaning component 1 and the position detection structure 62 are in contact. When the cleaning component 1 and the position detection structure 62 are in contact, the load of the drive motor 21 will be increased instantaneously, causing the current flowing through the drive motor 21 to increase. At this time, the detection unit can detect the increase in current in the drive motor 21, and the control unit will respond to control the drive motor 21 to turn off, so that the cleaning component can be accurately positioned at a preset angle position.

[0210] By setting a detection unit to detect whether the cleaning component 1 and the position detection structure 62 are in contact, the control unit can respond in a timely manner according to the detection result of the detection unit to shut down the drive motor 21. This can avoid the waste of energy by the drive motor 21 and also prevent the cleaning component 1 from falling out of the preset angle position due to the drive motor 21 not stopping in time. This is beneficial to improving the safety and reliability of the equipment, and also increases its efficiency and durability.

[0211] refer to Figures 5-9 According to some optional embodiments of the present invention, the detection unit is used to detect the current of the drive motor 21 to indirectly detect whether the cleaning component 1 is in contact with the position detection structure 62. Specifically, when the detection unit detects a sudden change and increase in the current of the drive motor 21, the cleaning component 1 is in contact with the position detection structure 62.

[0212] By using a detection unit to detect the current of the drive motor 21 to indirectly detect whether the cleaning component 1 is in contact with the position detection structure 62, the detection unit can detect changes in the motor current in a timely manner and stop the motor promptly when the cleaning component 1 and the position detection structure 62 come into contact, avoiding overload or damage to the motor. When the motor load increases, causing a sudden change in current, the control system can react quickly, reducing unnecessary energy waste. By reducing unnecessary motor running time and load, the service life of the motor and the entire cleaning equipment can be extended.

[0213] refer to Figures 5-9 According to some embodiments of the present invention, the position detection structure 62 is a flexible or elastic structure. By making the position detection structure 62 a flexible or elastic structure, the contact between the cleaning component 1 and the position detection structure 62 is flexible, and the flexible or elastic structure can absorb impact forces, avoiding damage caused by contact collisions, etc.

[0214] refer to Figures 5-9 According to some embodiments of the present invention, the position detection structure 62 is made of felt. The softness of felt helps to reduce wear and tear, and also helps to reduce the impact force when the cleaning component 1 and the position detection structure 62 come into contact. Furthermore, the positioning structure 61 made of felt is easy to install on the device body.

[0215] Optionally, the positioning structure 61 is provided on the device body via an adhesive layer or the like.

[0216] refer to Figures 5-9 The cleaning component has a positioning structure. When the positioning structure and the position detection structure come into contact in the rotation direction of the cleaning component, the cleaning component is positioned at a preset angle. By setting a positioning structure 61 on the cleaning component that specifically cooperates with the position detection structure 62, the reliability of the cleaning equipment is improved, so that the cleaning component 1 can be reliably positioned at the preset angle.

[0217] refer to Figures 5-9 According to some embodiments of the present invention, the positioning structure 61 is a flexible or elastic structure. By making the positioning structure 61 a flexible or elastic structure, the contact between the positioning structure 61 and the position detection structure 62 is flexible. The flexible or elastic structure can absorb impact forces and avoid damage caused by contact collisions, etc.

[0218] refer to Figures 7-9 According to some optional embodiments of the present invention, the positioning structure 61 is made of rubber. Rubber material has a certain cushioning effect, which can absorb impact force and reduce the risk of equipment damage due to collision.

[0219] Optionally, the cleaning component 1 includes a cleaning part 11 and a cleaning housing 12. The cleaning part 11 includes a flexible connecting arm 112 and a cleaning brush connected to one end of the flexible connecting arm 112. A position detection structure 62 is formed on the flexible connecting arm 112. Both the flexible connecting arm 112 and the position detection structure 62 are made of rubber, which facilitates the integral molding of the flexible connecting arm 112 and the position detection structure 62, thereby reducing the molding difficulty of the cleaning component 1.

[0220] refer to Figures 7-9 According to some embodiments of the present invention, the positioning structure 61 includes a plurality of positioning protrusions 611 spaced apart circumferentially along the cleaning component 1, and the position detection structure 62 includes a plurality of position detection protrusions 621 spaced apart circumferentially along the cleaning component 1, with each of the position detection protrusions 621 corresponding to one of the positioning protrusions 611. By including a plurality of positioning protrusions 611 spaced apart circumferentially along the cleaning component 1 in the positioning structure 61, and a plurality of position detection protrusions 621 spaced apart circumferentially along the position detection structure 62, the cooperation between the plurality of positioning protrusions 611 and the plurality of position detection protrusions 621 is beneficial to further improve the positioning effect of the positioning structure 6, so that the cleaning component 1 can be stably positioned at a preset angle position, thereby effectively avoiding adverse effects of the cleaning component 1 on the normal operation of other structures of the cleaning equipment.

[0221] refer to Figure 5 According to some embodiments of the present invention, the cleaning component 1 is located below the device body 5, and the position detection structure 62 is disposed on the bottom surface of the device body 5. By positioning the cleaning component 1 below the device body 5 and disposing of the position detection structure 62 on the bottom surface of the device body 5, the positions of the cleaning component 1 and the position detection structure 62 are reasonable, facilitating the cooperation between the position detection structure 62 and the positioning structure 61 disposed on the cleaning component 1.

[0222] refer to Figures 7-9According to some embodiments of the present invention, the cleaning assembly 1 includes a cleaning housing 12 and a cleaning component 11. The cleaning component 11 includes a mounting base 111 and a cleaning element. The cleaning element includes a connected connecting arm 112 and a cleaning part. The mounting base 111 is connected to the connecting arm 112 and is located inside the cleaning housing 12, which enhances the overall stability and durability. The mounting base 111 is fixed inside the cleaning housing 12, providing a solid foundation for the cleaning brush. This ensures the stability of the assembly even during high-speed rotation or strong cleaning operations, reduces vibration, and improves the overall durability and service life.

[0223] The cleaning part 113 is located outside the cleaning housing 12 and is suitable for contact with the working surface. The mounting base 111 is connected to the cleaning part 113 via a connecting arm 112. A through hole 123 is formed on the outer peripheral wall of the cleaning housing 12 for the connecting arm 112 to pass through. The drive assembly 2 is connected to the cleaning housing 12 to drive the cleaning assembly 1 to rotate. The position detection structure 62 is located on the connecting arm 112 and outside the cleaning housing 12. This ensures the movement of the cleaning part 113 while avoiding large openings in the cleaning housing 12, maintaining the structural strength of the housing, and reducing design complexity and manufacturing costs. By placing the position detection structure 62 on the connecting arm 112 and outside the cleaning housing 12, the cleaning housing 12 is prevented from obstructing the contact between the position detection structure 62 and the positioning structure 61. During the movement of the cleaning assembly 1, the position detection structure 62 formed on the connecting arm 112 also moves with the connecting arm 112 until it contacts the positioning structure 61. The position of the position detection structure 62 is reasonably positioned.

[0224] refer to Figures 7-9 According to some optional embodiments of the present invention, the cleaning component 1 has a positioning structure 61, which includes a positioning protrusion 611 formed on the connecting arm. When the positioning structure 61 and the position detection structure 62 are in contact in the rotation direction of the cleaning component, the cleaning component 1 is positioned at a preset angle position. The positioning structure 61 is simple to set, and the positioning protrusion 611 can be formed together with the connecting arm.

[0225] refer to Figures 7-9 According to some optional embodiments of the present invention, there are multiple cleaning elements 11, which are spaced apart circumferentially along the cleaning housing 12. By having multiple cleaning elements 11 and arranging them spaced apart circumferentially along the cleaning housing 12, it is beneficial to improve the cleaning effect of the cleaning elements 11.

[0226] According to some embodiments of the present invention, the bottom surface of the device body 5 is provided with a downward-looking sensor 7. At a preset angle position, the projection of the cleaning component 1 on the horizontal plane is spaced apart from the projection of the downward-looking sensor 7 on the horizontal plane. By making the projection of the cleaning component 1 on the horizontal plane and the projection of the downward-looking sensor 7 on the horizontal plane spaced apart at the preset angle position, the cleaning component 1 in the second position can avoid unnecessary obstruction of the downward-looking sensor 7, thereby preventing the cleaning component 1 from affecting the normal operation of the downward-looking sensor 7.

[0227] refer to Figures 7-9 At a preset angle position, the projection of cleaning component 1 on the horizontal plane is located within the projection of the device body 5 on the horizontal plane. This arrangement can prevent the cleaning component 1, which is in the second position, from interfering with or colliding with objects outside the device body 5 during the operation or movement of the cleaning equipment, thereby reducing or avoiding unnecessary damage to the cleaning component 1, or preventing the cleaning component 1 from hindering the normal operation of the cleaning equipment.

[0228] refer to Figures 7-9 According to some embodiments of the present invention, the cleaning assembly 1 includes a cleaning housing 12 and a cleaning component 11. The cleaning component 11 further includes a mounting base 111. The cleaning component 11 includes a connecting arm 112 and a cleaning part 113. The mounting base 111 is located inside the cleaning housing 12, and the cleaning part 113 is located outside the cleaning housing 12 and is adapted to contact the working surface. The mounting base 111 and the cleaning part 113 are connected by the connecting arm 112. A through hole 123 for the connecting arm 112 to pass through is formed on the outer peripheral wall of the cleaning housing 12. The driving assembly 2 is connected to the cleaning housing 12 to drive the cleaning assembly 1 to rotate. At a preset angle position, the cleaning part 113 is located on the left, right or rear side of the cleaning housing 12.

[0229] If the cleaning part 113 is located at the front of the cleaning housing 12 at a preset angle, it is prone to collision or interference with objects located in front of the cleaning equipment during its movement. This could hinder the normal operation of the cleaning equipment, or the cleaning part 113 could be easily jammed by these objects, causing unnecessary damage. By positioning the cleaning part 113 at the left, right, or rear of the cleaning housing 12 at a preset angle, collisions or interference with objects located in front of the cleaning equipment during its movement can be effectively avoided, which is beneficial for the normal operation of the cleaning equipment and helps extend its service life.

[0230] The cleaning assembly 1 includes a cleaning part 113 11. The drive assembly 2 is configured to drive the cleaning part 113 11 to move vertically between a first position and a second position, with the first position located below the second position. When the cleaning part 113 11 is in the second position and the cleaning assembly 1 is in contact with the position detection structure 62 in the rotation direction of the cleaning assembly 1, the cleaning assembly 1 is positioned at a preset angle. Thus, when the drive assembly 2 drives the cleaning assembly 1 to rotate and moves the cleaning part 113 11 to the second position, the cleaning part 113 11 can be accurately positioned at the preset angle, preventing it from affecting the normal operation of other components.

[0231] For example, when the cleaning work is completed or when a situation arises that may cause secondary pollution to the work surface, the drive motor 21 reverses and drives the cleaning component 1 to rotate in the second direction, so that the cleaning component 1 moves from the first position to the second position relative to the lifting component 31. When the cleaning component 1 moves to the second position and the positioning structure 61 and the position detection structure 62 contact in the second direction, the cleaning component 1 is at a preset angle position. At this time, the control unit controls the drive motor 21 to turn off.

[0232] refer to Figure 5 According to some embodiments of the present invention, the first cleaning module is located adjacent to the outer periphery of the device body 5. Optionally, the cleaning module 100 may be a side brush module. By placing the cleaning module 100 adjacent to the outer periphery of the device body 5, it is beneficial to expand the cleaning range of the cleaning module 100.

[0233] According to some optional embodiments of the present invention, there are multiple first cleaning modules, which are arranged at intervals along the circumference of the device body 5. By having multiple first cleaning modules arranged at intervals along the circumference of the device body 5, it is beneficial to increase the cleaning area of ​​the first cleaning modules, thereby further improving the cleaning effect of the cleaning equipment.

[0234] According to some optional embodiments of the present invention, a second cleaning module 100 is included, which is installed on the device body 5. The second cleaning module 100 is a main cleaning module 100, and the first cleaning module is an auxiliary cleaning module 100. For example, the second cleaning module 100 is a roller brush assembly, and the first cleaning module is a side brush assembly. The side brush assembly helps to improve the cleaning degree of the cleaning device on corners, wall bases, and other areas. By including a main cleaning module 100 and an auxiliary cleaning module 100 in the cleaning device, the cleaning effect of the cleaning device is improved.

[0235] According to a fifth aspect of the present invention, the cleaning system includes: the cleaning device and the cleaning base station described above, wherein the cleaning device is adapted to cooperate with the cleaning base station, the cleaning base station is used to clean the cleaning device, and the cleaning base station can also be used to charge the cleaning device.

[0236] According to the cleaning system of the present invention, by setting the above-mentioned cleaning equipment, the cleaning equipment is provided with a position positioning structure 6 including a positioning structure 61 and a position detection structure 62. The cooperation between the positioning structure 61 and the position detection structure 62 enables the cleaning component 1 to be positioned at a preset angle position. This can prevent the cleaning component 1 in the second position from staying in an inappropriate position, which would cause the cleaning component 1 to affect the normal operation of the other structures on the cleaning equipment.

[0237] Next, we will refer to Figures 5-9 Cleaning devices according to other embodiments of the present invention will be described.

[0238] refer to Figures 5-9 The cleaning equipment includes: equipment body 5, first cleaning module, positioning structure 61, position detection structure 62 and control unit, with the first cleaning module and control unit both located in equipment body 5.

[0239] The first cleaning module is installed on the device body 5 and includes a cleaning component 1 and a drive component 2. The cleaning component 1 includes a cleaning housing 12 and cleaning parts. The cleaning parts include a mounting base 111 and multiple cleaning parts 11, which are spaced apart circumferentially along the cleaning housing 12.

[0240] The cleaning component 11 is used to contact the working surface to clean the working surface. The drive component 2 is connected to the cleaning component 1. The drive component 2 is used to drive the cleaning component 1 to rotate and to drive the cleaning component 1 to move between a first position and a second position in the up-down direction. The first position is located below the second position.

[0241] The cleaning component 11 includes a connected connecting arm 112 and a cleaning brush. A mounting base 111 is connected to the connecting arm 112 and is located inside the cleaning housing 12. The mounting base 111 is fixed inside the cleaning housing 12. The cleaning part 113 is located outside the cleaning housing 12 and is suitable for contact with the working surface. The mounting base 111 and the cleaning part 113 are connected by the connecting arm 112. A through hole 123 for the connecting arm 112 to pass through is formed on the outer peripheral wall of the cleaning housing 12. The driving component 2 is connected to the cleaning housing 12 to drive the cleaning component 1 to rotate. The position detection structure 62 is provided on the connecting arm 112 and is located outside the cleaning housing 12.

[0242] The cleaning component 1 is movable in the vertical direction. When the cleaning module 100 is applied to the cleaning equipment, the cleaning component 1 can be raised relative to the equipment body 5 to separate the cleaning component 1 from the working surface when the cleaning equipment performs the cleaning task. This avoids the cleaning component 1 from causing secondary pollution to the working surface or avoids the cleaning component 1 from colliding or interfering with the working surface at certain positions.

[0243] The positioning structure 61 is located on the cleaning component 1, and the position detection structure 62 is located on the device body 5. When the cleaning component 1 is in the second position and the positioning structure 61 and the position detection structure 62 are in contact in the rotation direction of the cleaning component 1, the cleaning component 1 is positioned at a preset angle position.

[0244] The drive assembly 2 includes a drive motor 21 for driving the cleaning assembly 1 to rotate. The control unit is electrically connected to the drive motor 21 to control the drive motor 21. The control unit is used to control the drive motor 21 to turn off when the cleaning assembly 1 is positioned at a preset angle.

[0245] For example, when the cleaning work is completed or when a situation arises that may cause secondary pollution to the work surface, the drive motor 21 reverses and drives the cleaning component 1 to rotate in the second direction, so that the cleaning component 1 moves from the first position to the second position relative to the lifting component 31. When the cleaning component 1 moves to the second position and the positioning structure 61 and the position detection structure 62 contact in the second direction, the cleaning component 1 is at a preset angle position. At this time, the control unit controls the drive motor 21 to turn off.

[0246] The cleaning equipment also includes a detection unit, which is used to directly or indirectly detect whether the positioning structure 61 and the position detection structure 62 are in contact. The control unit is used to control the drive motor 21 to shut down when the detection unit detects that the positioning structure 61 and the position detection structure 62 are in contact.

[0247] The detection unit is used to detect the current of the drive motor 21 to indirectly detect whether the positioning structure 61 and the position detection structure 62 are in contact. Specifically, when the detection unit detects a sudden change and increase in the current of the drive motor 21, the positioning structure 61 and the position detection structure 62 are in contact.

[0248] At least one of the positioning structure 61 and the position detection structure 62 is a flexible or elastic structure. The positioning structure 61 is made of felt, and the position detection structure 62 is made of rubber. Optionally, the positioning structure 61 is attached to the device body via an adhesive layer or the like.

[0249] The positioning structure 61 includes a plurality of positioning protrusions 611 spaced apart along the circumference of the cleaning component 1, and the position detection structure 62 includes a plurality of position detection protrusions 621 spaced apart along the circumference of the cleaning component 1, with each of the plurality of position detection protrusions 621 corresponding to one of the plurality of positioning protrusions 611.

[0250] The cleaning component 1 is located below the device body 5, and the position detection structure 62 is disposed on the bottom surface of the device body 5. The position detection structure 62 includes a position detection protrusion 621 formed on the connecting arm 112.

[0251] The bottom surface of the device body 5 is provided with a downward-looking sensor 7. At a preset angle position, the projection of the cleaning component 1 on the horizontal plane is separated from the projection of the downward-looking sensor 7 on the horizontal plane. By making the projection of the cleaning component 1 on the horizontal plane and the projection of the downward-looking sensor 7 on the horizontal plane separate at the preset angle position, the cleaning component 1 in the second position can avoid unnecessary obstruction of the downward-looking sensor 7, thereby preventing the cleaning component 1 from affecting the normal operation of the downward-looking sensor 7.

[0252] At a preset angle position, the projection of the cleaning component 1 onto the horizontal plane is within the projection of the device body 5 onto the horizontal plane. This arrangement prevents the cleaning component 1, located in the second position, from interfering with or colliding with objects outside the device body 5 during the operation or movement of the cleaning equipment, thereby reducing or avoiding unnecessary damage to the cleaning component 1, or preventing the cleaning component 1 from hindering the normal operation of the cleaning equipment. At the preset angle position, the cleaning part 113 is located on the left, right, or rear side of the cleaning housing 12.

[0253] The first cleaning module can be a side brush module, located adjacent to the outer periphery of the device body 5. Multiple first cleaning modules are arranged at intervals along the circumference of the device body 5. The cleaning device also includes a second cleaning module 100, which is installed on the device body 5. The second cleaning module 100 is the main cleaning module 100, and the first cleaning modules are auxiliary cleaning modules 100. The second cleaning module 100 is a roller brush assembly.

[0254] For example, when cleaning is completed or a situation arises that could cause secondary contamination of the work surface, the drive motor 21 reverses direction, driving the cleaning component 1 to rotate in the second direction. The constraint component 33 constrains the lifting component 31 to rotate in the second direction, so that the cleaning part 113 moves relative to the lifting component 31 from the first position upward toward the second position. When the cleaning component 1 moves to the second position and the positioning structure 61 and the position detection structure 62 contact in the second direction, the cleaning component 1 is at a preset angle position. The detection unit detects that the positioning structure 61 is in contact with the position detection structure 62. At this time, the control unit controls the drive motor 21 to shut down based on the detection result of the detection unit.
