[0040] Reference Figures 1-5 This embodiment provides a cleaning device, including a housing 1, a cleaning component module, and a position adjustment mechanism;

[0041] The position adjustment mechanism includes a drive module 30, a transmission module 31, and a sliding module 32;

[0042] The drive module 30 and the sliding module 32 are respectively disposed on the housing 1, and the drive module 30 is connected to the sliding module 32 through the transmission module 31. The drive module 30 is used to drive the sliding module 32 to perform linear motion on the housing 1 through the transmission module 31.

[0043] The cleaning module is disposed on the housing 1 and is arranged correspondingly to the sliding module 32. The cleaning module is connected to the sliding module 32. The sliding module 32 is used to drive the cleaning module to perform vertical lifting and / or horizontal extension and retraction relative to the housing 1.

[0044] In the above embodiments, the cleaning device includes a housing 1, a cleaning component module, and a position adjustment mechanism. The housing 1 serves as the basic frame of the entire device, providing an installation platform and protecting the internal components. The cleaning component module is the key part for performing the cleaning task. The position adjustment mechanism comprises three main parts: a drive module 30, a transmission module 31, and a sliding module 32. The drive module 30 and the sliding module 32 are respectively mounted on the housing 1, and the drive module 30 is connected to the sliding module 32 through the transmission module 31. That is, the drive module 30 is fixed to one side of the housing 1. The transmission module 31 is connected to the sliding module 32, enabling effective power transmission. This ensures that the drive module 30 can drive the sliding module 32 to move linearly on the housing 1 via the transmission module 31. The sliding module 32 slides left and right along the track set on the housing 1, achieving not only linear motion but also providing the power source for the cleaning module to move up and down and extend and retract. The cleaning module and the sliding module 32 are arranged correspondingly, preferably on opposite sides of the housing. The sliding module 32 is responsible for... The key component is the linear motion that is converted into the vertical lifting or horizontal extension / retraction motion of the cleaning module. The vertical lifting motion refers to the up-and-down movement of the cleaning module, while the horizontal extension / retraction motion refers to the retraction or outward expansion of the cleaning module along the horizontal direction inward or outward in the housing 1. This allows the drive module 30 to drive the sliding module 32 to perform linear motion through the transmission module 31, thus realizing the lifting and extension / retraction functions of the cleaning module. When the sliding module 32 moves to the left or right, it will drive the cleaning module to move up and down or left and right. For example, when it is necessary to raise the mop to avoid wetting the carpet, the sliding module 32 will push the cleaning module upward according to the instruction; while when cleaning along the edge of the wall or furniture, the sliding module 32 will cause the cleaning module to expand outward. Therefore, by enabling the cleaning module to perform vertical lifting or horizontal extension / retraction motion as needed, the wet mop can be effectively prevented from directly contacting the carpet, thereby preventing the carpet from getting wet or contaminated by dirt on the mop. At the same time, it ensures that when cleaning the edges, the mop can cover more areas, reduce dead corners, and improve cleaning efficiency and quality.

[0045] Reference Figures 1-5 In one embodiment, the drive module 30 includes a drive motor 301 and a drive gear 302, and the transmission module 31 includes a transmission track.

[0046] The drive motor 301 is fixedly connected to the housing 1, and the drive gear 302 is connected to the output shaft of the drive motor 301. The transmission track includes a track body 3101 and a plurality of racks 3102. The racks 3102 are disposed on the track body 3101 and mesh with the drive gear 302. The drive gear 302 is connected to the sliding module 32 through the track body 3101.

[0047] In the above embodiment, the drive module 30 consists of a drive motor 301 and a drive gear 302. The drive motor 301 serves as a power source and is fixedly connected to the housing 1, responsible for providing mechanical energy to drive the entire system. The drive gear 302 is directly connected to the output shaft of the drive motor 301, and the rotation of the motor drives the drive gear 302 to rotate synchronously. The transmission module 31 includes a transmission track, which consists of a track body 3101 and multiple racks 3102. These racks 3102 are spaced apart on the inner side of the track body 3101 to ensure that they can be adapted to and tightly meshed with the drive gear 302. When the drive motor 301 starts, the motor drives the drive gear 302 to rotate, and the gear then drives the track body 3101 to move continuously through the racks 3102.

[0048] Both ends of the transmission track are connected to the sliding module 32, so that the movement of the track body 3101 can be directly converted into the linear movement of the sliding module 32. This allows the rotational kinetic energy of the drive motor 301 to be efficiently transmitted to the sliding module 32 through the drive gear 302 and the transmission track, thereby realizing the vertical lifting or horizontal extension and retraction function of the cleaning module. The rotational force generated by the drive motor 301 is transmitted to the rack 3102 on the transmission track through the drive gear 302, causing the track body 3101 to start cyclic movement. Since the track body 3101 is directly connected to the sliding module 32, this cyclic movement is directly converted into the linear displacement of the sliding module 32, making the power transmission more stable and reliable.

[0049] Reference Figures 1-3 In one embodiment, the transmission track further includes a buckle plate 3103, which is disposed at the end of the track body 3101. The end of the sliding module 32 is provided with a snap-fit ​​groove 34. The track body 3101 is detachably connected to the snap-fit ​​groove 34, and the buckle plate 3103 is in contact with the inner side of the sliding module 32.

[0050] In the above embodiment, the transmission track also includes a snap-fit ​​plate 3103, which is disposed at both ends of the track body 3101, with one snap-fit ​​plate 3103 at each end, making the track body 3101 and the snap-fit ​​plate 3103 form a T-shaped structure. The end of the sliding module 32 is provided with a snap-fit ​​groove 34, which is designed to be open at the top and its width is slightly larger than the thickness of the track body 3101. The track body 3101 is detachably connected in the snap-fit ​​groove 34. The detachable connection is preferably a snap-fit ​​connection to ensure that the track body 3101 can be smoothly engaged. When the end of the track body 3101 is inserted into the snap-fit ​​groove 34 of the sliding module 32, the snap-fit ​​plate 3103 will be located in the inner direction of the sliding module 32, that is, on the side away from the inner pulley 3111, thereby ensuring close contact and effective connection between the two. This allows the track body 3101 to pull the sliding module 32 to move linearly through the snap-fit ​​plate 3103 during movement. Since the track body 3101 can be separated from the sliding module 32 through simple insertion and removal operations, the installation and disassembly process is effectively simplified without the need for complicated tools or steps.

[0051] Reference Figures 1-5 In one embodiment, the transmission module 31 further includes a sliding member disposed on the housing 1, the sliding member being in contact with the track body 3111, and the track body 3111 being connected to the sliding module 32 via the sliding member.

[0052] In the above embodiment, the sliding member is disposed on the housing 1 to support and guide the transmission track. The track body 3101 not only meshes with the drive gear 302 through the rack 3102, but also contacts the sliding member, so that the track body 3111 is connected to the sliding module 32 through the sliding member, thereby ensuring that the transmission track remains taut throughout the entire operation and can move smoothly along the set path. The sliding member preferably includes at least two oppositely arranged outer pulleys 3110 and at least two oppositely arranged inner pulleys 3111. The pulleys are preferably fixed pulleys. The outer pulleys 3110 are located on the side closer to the drive motor 301, and they contact the outer side of the track body 3101 to ensure that the track body 3101 maintains appropriate tension and stability during operation. The inner pulleys 3111 are disposed at both ends of the sliding module 32 in the linear motion direction, and are connected to the track body 3101. The inner sides of the track body 3101 are in contact with each other, and each inner pulley 3111 is located at the end of the sliding module 32, ensuring that the track body 3101 does not deviate from the track during operation and maintains its tension. Since the inner pulleys 3111 are in contact with the inner side of the track body 3101, they play a supporting and guiding role, preventing the track body 3101 from deviating or falling off when running at high speed or being impacted. At the same time, the transmission track, through the layout of the drive gear 302, two outer pulleys 3110, and two inner pulleys 3111, forms a convex structure with the sliding module 32. The synergistic effect of the outer pulleys 3110 and inner pulleys 3111 effectively reduces friction and wear, extends the service life of the equipment, and the track body 3101 can maintain high stability and accuracy during operation, avoiding slippage and ensuring high efficiency of power transmission.

[0053] Reference Figures 1-5 In one embodiment, the sliding module 32 includes a slide groove 320 and a slide bar 321. The slide groove 320 is disposed on the housing 1, and the slide bar 321 is slidably connected in the slide groove 320. A limiting hole 322 is provided at the bottom of the slide groove 320. The limiting hole 322 extends a specified distance along the length direction of the slide groove 320, and the cleaning component module is connected to the slide bar 321 through the limiting hole 322.

[0054] In the above embodiment, the sliding module 32 includes a slide groove 320 and a slide bar 321. The slide groove 320 is disposed on the housing 1, has a certain depth and is rectangular, and has a limiting hole 322 at its bottom. The limiting hole 322 extends a specified distance along the length direction of the slide groove 320 to ensure that the slide bar 321 slides smoothly inside it. The cleaning module is connected to the cleaning module through the limiting hole 322. The design of the slide groove 320 not only provides a movement track for the slide bar 321, but also ensures that the slide bar 321 will not deviate from the track during the movement.

[0055] Sliding strips 321 are slidably connected within the slide groove 320. Preferably, multiple sliding strips 321 are arranged symmetrically, and adjacent sliding strips 321 are interconnected via connecting plates. Each sliding strip 321 corresponds to a limiting hole 322 for engagement, ensuring precise position control within the slide groove 320. The limiting hole 322 at the bottom of the slide groove 320 is also rectangular, but its length is less than the length of the slide groove 320 itself. Specifically, when the drive system starts, the transmission track pulls the sliding strips 321 in the sliding module 32 via the buckle plate 3103. The sliding strips 321 slide along the limiting holes 322 in the slide groove 320, driving the connected cleaning component module to move up and down or expand left and right. The precise engagement of the slide groove 320 and the sliding strips 321 ensures the accuracy and stability of the cleaning component module's movement, avoiding jamming caused by poor sliding. The movement of the sliding strips 321 within the slide groove 320 is effectively constrained, reducing unnecessary friction and wear, and extending the equipment's service life.

[0056] Reference Figures 1-5 In one embodiment, the position adjustment mechanism further includes a plurality of position switches, and a switch sensing part 323 is provided on the slide bar 321. The plurality of position switches are arranged at intervals on the housing 1, and the position switches are arranged corresponding to the switch sensing part 323.

[0057] In the above embodiment, the position adjustment mechanism also includes multiple position switches. These position switches are used to detect the specific position of the slide bar 321 and trigger corresponding actions according to its position. Specifically, the slide bar 321 is provided with a switch sensing part 323. Multiple position switches are arranged at intervals on the housing 1 and correspond to the switch sensing part 323. There are usually three position switches, namely the first position switch 330, the second position switch 331 and the third position switch 332. They are arranged close to the slide groove 320 in sequence, and the interval between the three is different. The first position switch 330 is located at the leftmost end of the slide groove 320, which usually corresponds to the initial or retracted position of the cleaning module. The second position switch 331 is located in the middle position, which usually corresponds to the middle working state of the cleaning module, such as cleaning while in contact with the ground. The third position switch 332 is located at the rightmost end of the slide groove 320, which usually corresponds to the maximum outward expansion position of the cleaning module, used to cover more cleaning areas. Each position switch is coupled with a switch sensing unit 323 on the slider 321. When the slider 321 moves the switch sensing unit 323 to different positions, the switch sensing unit 323 will trigger the corresponding position switch, thereby sending a signal to the control system.

[0058] Based on feedback from the position switches, the control system controls the motor to rotate forward or backward, thereby adjusting the position of the cleaning module. For example, when the slider 321 moves to the first position switch 330, the switch sensor 323 triggers the position switch. Upon receiving the signal, the system stops the motor, and the cleaning module is in a retracted state to prevent the carpet from getting wet. Similarly, when the slider 321 moves to the second position switch 331 or the third position switch 332, the cleaning module enters either the intermediate working state or the maximum extended state, respectively, to adapt to different cleaning needs. Through the cooperation of the position switches and the switch sensor 323, the optimal position of the cleaning module can be ensured in different environments, improving cleaning efficiency and effectiveness, and making the motion control of the entire system more precise and intelligent.

[0059] Reference Figures 1-5 In one embodiment, the cleaning component module includes a cleaning component body 20 and a connecting slider 21. The cleaning component body 20 is disposed on the side of the housing 1 away from the slide groove 320. The connecting slider 21 is fixedly connected to the cleaning component body 20, and one end of the connecting slider 21 away from the cleaning component body 20 passes through the limiting hole 322 and is connected to the slide bar 321.

[0060] In the above embodiment, the cleaning component module includes two main parts: the cleaning component body 20 and the connecting slider 21. The cleaning component body 20 is preferably a mop. The cleaning component body 20 is located on the side of the housing 1 away from the slide groove 320, that is, the cleaning component body 20 is below the housing 1 and the slide groove 320 is above the housing 1. It is set in a specially designed receiving space so that the cleaning component body 20 and the housing 1 maintain a certain distance. The receiving space ensures that the cleaning component body 20 can move freely without being obstructed by the housing 1, thereby realizing lifting or outward movement. The cleaning component body 20 is connected to the slide bar 321 through the connecting slider 21. One end of the connecting slider 21 is fixed on the cleaning component body 20, and the other end passes through the limiting hole 322 and is connected to the slide bar 321.

[0061] The design of the connecting slider 21 allows it to move freely within the limiting hole 322 while maintaining a firm connection with the cleaning component body 20. When the drive system is started, the slider 321 slides along the slide groove 320 and drives the cleaning component body 20 to perform corresponding vertical lifting or horizontal extension and retraction movements through the connecting slider 21. When the slider 321 is driven by the transmission belt and slides along the slide groove 320, it transmits power to the cleaning component body 20 through the connecting slider 21. The precise guiding effect of the connecting slider 21 within the limiting hole 322 ensures that the cleaning component body 20 can move accurately up and down or left and right. This design not only improves the flexibility of the system but also enhances the user experience, making it perform better in different environments.

[0062] Reference Figures 1-3 In one embodiment, the slider 321 includes a limiting part 3210, a flat part 3211, and an inclined part 3213. The limiting part 3210 and the inclined part 3213 are respectively disposed at both ends of the flat part 3211, and the limiting part 3210 and the flat part 3211 are disposed perpendicular to each other. The limiting part 3210, the flat part 3211, and the inclined part 3213 together form a position adjustment hole 3214. The connecting slider 21 is located in the position adjustment hole 3214 and is slidably connected to the flat part 3211 or the inclined part 3213.

[0063] In the above embodiment, the slider 321 includes three parts: a limiting part 3210, a flat part 3211, and an inclined part 3213. The limiting part 3210 and the flat part 3211 are respectively disposed at both ends of the flat part 3211, and the limiting part 3210 is perpendicular to the flat part 3211. The slider 321 is hollow in whole, so that the limiting part 3210, the flat part 3211, and the inclined part 3213 together form a position adjustment hole 3214 for accommodating the connecting slider 21 and allowing it to slide inside it.

[0064] The part of the connecting slider 21 that contacts the flat part 3211 or the inclined part 3213 is designed to be semi-circular, ensuring that the slider can slide smoothly at different angles, thereby driving the cleaning component body 20 to complete the up-and-down lifting or horizontal extension and retraction actions. When two sliders 321 are connected, each slider 321 has a locking groove 34 at both ends, located on the limiting part 3210 of the previous slider 321 and the inclined part 3213 of the next slider 321, respectively, to ensure stable connection and transmission efficiency between sliders 321. Through the design of the inclined part 3213 and the flat part 3211, the cleaning component body 20 can automatically complete the lifting action without additional drive, improving the response speed and energy efficiency ratio.

[0065] When the mop is not mopping or cleaning on the carpet, the cleaning module is in position one: the slider 321 contacts the first position switch 330, the motor stops rotating after receiving the position switch signal, and the cleaning module body 20 is retracted into the machine body.

[0066] When the robot vacuum cleaner starts mopping, the motor rotates forward, driving the toothed track body to move the slider 321 in a straight line. The slider 321 has a flat part 3211 and an inclined part 3213. The slider and the cleaning part body 20 are fixedly connected. When the slider 321 moves in a straight line to the outside of the machine body, the slider slides from the high point of the slope to the low point due to gravity, thereby driving the cleaning part body 20 to move downward. When the slider 321 moves a certain distance, it will trigger the second positioning switch 331. After receiving the positioning switch signal, the motor stops rotating, and the cleaning part body 20 moves down to position two and contacts the ground to clean.

[0067] When the robot vacuum encounters and detects a carpet, the motor reverses and drives the toothed track body to move the slide bar 321 in a straight line towards the inside of the body. The connecting slider 21, which is connected to the cleaning component body 20, is limited by the limiting hole 322 of the housing 1 and cannot move continuously with the slide bar 321. The slider will move upward along the inclined surface 3213 of the slide bar 321, and the cleaning component body 20 connected to the slider 21 will move upward to the cleaning component module position one. The first positioning switch 330 on the slide bar 321 is triggered, and the motor stops rotating after receiving the signal from the first positioning switch 330.

[0068] When the robot is cleaning along the wall or the edge of the furniture during the mopping process, the motor starts to rotate forward and drives the toothed track body to move the slider 321 in a straight line to the outside of the body. The slider moves together with the cleaning part body 20 and the slider 321. When the cleaning part body 20 moves from position two to position three, the slider 321 is in the third position switch. After the motor receives the signal from the third position switch 332, it stops rotating.

[0069] When cleaning is not along a wall or edge, the motor reverses to drive the toothed track body, causing the slide bar 321 to move linearly inwards towards the machine body. The slide bar, along with the cleaning module and the cleaning bar 321, moves together. When the cleaning module moves from position three to position two, the slide bar 321 triggers the second stop switch 331. Upon receiving the signal from the second stop switch 331, the motor stops rotating. During operation, the cleaning module can move from position one to position two, from position two to position three, or from position two to position one; it can also move from position three to position two, then from position two to position three, or from position two to position one. Figure 1 The first position diagram of the cleaning module shows the cleaning module located inside the machine body, with the cleaning module in a raised state; Figure 4 The second position diagram of the cleaning module shows the cleaning module in the working state, which is the cleaning module in the descending state; Figure 5 The third position diagram of the cleaning module shows the cleaning module extending outwards from the outer side of the housing in a horizontal direction, so that the cleaning module is in an expanded state.

[0070] Reference Figures 1-3 In one embodiment, the main body 20 of the cleaning component is further provided with a plurality of guide posts 22, and the housing 1 is further provided with a plurality of guide holes 4 corresponding to the guide posts 22. The guide posts 22 are disposed through the guide holes 4, and the guide holes 4 extend a specified distance along the length direction of the housing 1.

[0071] In the above embodiments, the cleaning component body 20 is provided with multiple guide posts 22, and the housing 1 is provided with multiple guide holes 4 corresponding to the guide posts 22. The guide posts 22 are disposed through these guide holes 4, which extend a specified distance along the length direction of the housing 1. The length direction of the housing 1 is also the direction of movement of the slider 321, ensuring that the cleaning component body 20 can perform precise vertical lifting or horizontal extension and retraction along a predetermined path. The guide posts 22 are usually designed to be cylindrical, with a diameter slightly smaller than the inner diameter of the guide holes 4, to facilitate sliding and reduce friction. For example, a guide post 22 is provided on each of the adjacent sides of the cleaning component body 20 to ensure that the cleaning component body 20 does not tilt or deviate when moving up and down or expanding left and right, thereby improving the stability of the cleaning device.

[0072] This embodiment also discloses a sweeping robot, including the cleaning device described in any of the above embodiments. The sweeping robot integrating the cleaning device has a mop lifting and outward expansion function, which allows the mop to automatically adjust its height according to different floor types. For example, when encountering a carpet, the mop can be lifted to avoid wetting or soiling the carpet, thus improving cleaning flexibility. Secondly, the mop can be extended outward to ensure thorough cleaning along the edges of walls or furniture, reducing dead corners.

[0073] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
