[0002] Cleaning equipment, such as cleaning robots, is a type of household cleaning device that can autonomously clean surfaces without manual operation and has a wide range of applications. Cleaning robots use mops, roller brushes, and other cleaning components to effectively remove wastewater, dust, and other contaminants from floors. However, a drawback is the potential for secondary pollution from these cleaning components, such as dripping water or falling dust. Especially when the cleaning component stops or traverses obstacles like carpets or thresholds, it can easily leak or be scraped off, contaminating the floor. Utility Model Content

In this state, the movable shield is in a scraping state. Therefore, this cleaning structure effectively prevents cross-contamination between the cleaning component and the surface to be cleaned through the movable shield, while the scraper on the movable shield removes contaminants from the surface, keeping the surface clean and improving cleaning efficiency.

[0079] Please see Figures 1 to 19 This application provides a cleaning structure 10 and a cleaning device 1 including the cleaning structure 10. The cleaning structure 10 includes a movable shield 200 with a scraper 240. By switching the state of the movable shield 200, the cleaning structure 10 can switch between a scraping state and a shielding state. This can prevent cross-contamination between the cleaning component 100 and the surface to be cleaned, and also remove contaminants from the surface to be cleaned by the scraper 240 on the movable shield 200, thereby keeping the surface to be cleaned clean and improving the cleaning effect.

[0080] The cleaning device 1 in this application embodiment can be a cleaning robot, a floor scrubber, etc., but is not limited to these. Taking a cleaning robot as an example, the cleaning robot is used to clean contaminants on the ground surface awaiting cleaning. Please refer to... Figure 1 and Figure 2In this embodiment, the cleaning device 1 includes a housing 20, a lifting drive, and a cleaning structure 10. The lifting drive is disposed within the housing 20, and the cleaning component 100 of the cleaning structure 10 is connected to the output end of the lifting drive. Of course, the cleaning device 1 may also include conventional components of existing cleaning robots, such as wheels and batteries. The lifting drive can drive the cleaning structure 10 to rise and fall as a whole, allowing the movable shield 200 to move between the cleaning component 100 and the ground. This enables the cleaning device 1 to adapt to different ground heights or obstacle environments, achieving active scraping of dirt. Furthermore, it effectively solves the problem of contaminants falling from the cleaning component 100, such as dripping wastewater or dust causing secondary pollution, thus improving cleaning effectiveness and user experience.

[0081] See Figure 3 and Figure 4 The cleaning structure 10 includes a cleaning component 100, a movable shield 200, and a power mechanism 300. The cleaning component 100 is used to clean the surface to be cleaned. For example, the cleaning component 100 can be rotatably connected to the housing 20, allowing it to rotate relative to the housing 20, thereby cleaning contaminants on the ground by rolling. Alternatively, the cleaning component 100 can be fixedly connected to the housing 20, keeping it stationary. In this case, the cleaning component 100 can move with the cleaning device 1 on the ground to wipe away contaminants. The movable shield 200 has scraper strips 240 on its edge, which are used to scrape away residual contaminants on the ground. The movable shield 200 can be located on either side of the cleaning component 100, as long as it can move relative to the cleaning component 100 to achieve the functions of shielding and scraping. In this embodiment, the movable shield 200 is positioned behind the cleaning component 100. That is, when the cleaning structure 10 moves forward with the cleaning device 1, the movable shield 200 is located behind the cleaning component 100, so that the movable shield 200 can adapt to the cleaning component 100. A power mechanism 300 is mounted on the cleaning component 100 and is driven by the movable shield 200 to drive the movable shield 200 to move relative to the cleaning component 100, allowing the movable shield 200 to switch between different operating states.

[0082] Specifically, the movable shield 200 has at least a scraping state and a shielding state. In the scraping state, the movable shield 200, under the action of the power mechanism 300, drives the scraper 240 towards the surface to be cleaned, so that the scraper 240 can scrape off the contaminants on the surface to be cleaned, which is especially suitable for solving the problem of cleaning stubborn stains. It can be understood that in order to scrape off the contaminants on the surface to be cleaned, the power mechanism 300 can drive the scraper 240 to make direct contact with the ground, or it can drive the scraper 240 to maintain a certain gap with the ground to avoid scratching the ground. In the shielding state, the movable shield 200, under the action of the power mechanism 300, moves between the cleaning component 100 and the surface to be cleaned to separate the cleaning component 100 from the surface to be cleaned. Furthermore, the movable shield 200 also has a retracted state. When cleaning the surface to be cleaned using the cleaning component 100, the movable shield 200 and the scraper 240 need to be retracted. At this time, the movable shield 200, under the action of the power mechanism 300, drives the scraper 240 away from the surface to be cleaned. Specifically, it drives the scraper 240 to rise to avoid scratching the surface to be cleaned.

[0083] In this embodiment of the cleaning structure 10, when crossing obstacles such as carpets or during pure sweeping, the movable shield 200 is driven by the power mechanism 300 to move relative to the cleaning component 100, causing the movable shield 200 to descend between the cleaning component 100 and the surface to be cleaned, thus separating the cleaning component 100 and the surface to be cleaned. At this time, the movable shield 200 is in a blocking state, effectively preventing wastewater and other contaminants on the cleaning component 100 from directly dripping onto the surface to be cleaned, while also preventing secondary contamination caused by obstacles on the surface to be cleaned contacting the cleaning component 100. When it is necessary to clean the surface to be cleaned, the power mechanism 300 drives the movable shield 200 to move the scraper 240 towards the surface to be cleaned, actively cleaning contaminants from the surface. At this time, the movable shield 200 is in a scraping state. Therefore, the cleaning structure 10 can effectively block cross-contamination between the cleaning component 100 and the surface to be cleaned through the movable shield 200, while the scraper 240 on the movable shield 200 can remove residual water and other pollutants from the surface to be cleaned, thus combining the functions of shielding and preventing contamination and actively scraping contaminants, significantly improving the cleaning effect.

[0084] See Figure 6 As shown in Figures 7(a) and 7(b), in some embodiments, the thickness of the scraper 240 is gradually reduced in the direction away from the movable shield 200, i.e., the thickness of the scraper 240 gradually decreases in the direction away from the movable shield 200. Here, the thickness of the scraper 240 refers to its radial dimension in the cleaning member 100. Therefore, the thinner end of the scraper 240 away from the movable shield 200 makes it easier to scrape up contaminants, thereby enhancing the ability to remove contaminants.

[0085] In some embodiments, referring to Figures 7(a) and 7(b), the scraper 240 can be configured as an arc-shaped plate, conforming to the outer periphery of the cleaning member 100, so that the scraper 240 can scrape away contaminants when driven to move with the movable shield 200. Optionally, the scraper 240 can also be configured as a straight plate, that is, the scraper 240 has a long strip-shaped flat plate structure, in which case the scraper 240 can also play the role of scraping away contaminants.

[0086] Furthermore, when the scraper 240 is in the shape of an arc plate, the side of the scraper 240 away from the cleaning component 100 is located within the first arc surface M1, and the outer side of the movable shield 200 is located within the second arc surface M2. The first arc surface M1 may coincide with the second arc surface M2, or the first arc surface M1 and the second arc surface M2 may have a gap in the radial direction of the first arc surface M1.

[0087] For example, referring to Figure 7(a), the figure shows the case where the first arc surface M1 and the second arc surface M2 coincide, wherein the side of the scraper 240 facing away from the cleaning component 100 and the outer side of the movable shield 200 are located within the same arc surface. When the scraper 240 moves relative to the cleaning component 100 with the movable shield 200, the outer side of the scraper 240 and the outer side of the movable shield 200 move relative to the cleaning component 100 along the same path. Therefore, if the movable shield 200 does not interfere with the cleaning component 100 or the ground during its movement, the scraper 240 will also not interfere with the cleaning component 100 or the ground. This reduces the difficulty of controlling the movement of the movable shield 200 and the scraper 240, making the movement of the scraper 240 with the movable shield 200 smoother.

[0088] For example, referring to Figure 7(b), the figure shows a case where the first arc surface M1 and the second arc surface M2 have a gap H in the radial direction of the first arc surface M1. In this case, the side of the scraper 240 away from the cleaning component 100 is closer to the cleaning component 100 than the outer side of the movable shield 200, resulting in a gap H between the side of the scraper 240 away from the cleaning component 100 and the outer side of the movable shield 200. Of course, in other cases, the side of the scraper 240 away from the cleaning component 100 can also be set further away from the cleaning component 100 than the outer side of the movable shield 200, which also results in a gap H between the side of the scraper 240 away from the cleaning component 100 and the outer side of the movable shield 200. Therefore, when the scraper 240 is connected to the cleaning component 100, it is not necessary to ensure a complete overlap, which can reduce the installation difficulty and improve the installation efficiency. It should be understood that when the spacing H is small enough, although the side of the scraper 240 away from the cleaning component 100 does not coincide with the outer side of the movable shield 200, the side of the scraper 240 away from the cleaning component 100 and the outer side of the movable shield 200 can be regarded as being roughly located in the same arc surface.

[0089] In some embodiments, the edge of the movable shield 200 away from the scraper 240 is straight and has at least one reinforcing protrusion 250, which protrudes circumferentially from the movable shield 200. See also Figure 3 , Figure 9 and Figure 10 The movable shield 200 is provided with two reinforcing protrusions 250 on the side away from the scraper 240, i.e. the top of the movable shield 200. The reinforcing protrusions 250 extend from one side of the movable shield 200 and are set in an arc shape. By setting the reinforcing protrusions 250, the structural strength of the movable shield 200 can be enhanced, the deformation of the movable shield 200 in the radial direction of the cleaning part 100 can be reduced, and the problem of deformation and jamming of the movable shield 200 can be prevented.

[0090] Optionally, in some embodiments, the scraper strip 240 is made of a flexible material. The flexible material refers to a soft material with good flexibility and plasticity, while also possessing a certain degree of elasticity and conformability. For example, the flexible material can be rubber, thermoplastic elastomer (TPE), flexible polyethylene (PE), polyvinyl chloride (PVC), etc. A scraper strip 240 made of a flexible material can better conform to the ground, thereby quickly scraping away excess water and dirt, ensuring the ground dries quickly, and avoiding scratches on the ground.

[0091] In some embodiments, the scraper 240 has a contaminant collection chamber 241 recessed on the side facing the cleaning member 100. For example, see... Figure 18 and Figure 19 Both ends of the scraper 240 are designed as closed structures, and a contaminant collection chamber 241 is formed by a recess in the middle area of ​​the scraper 240. This prevents contaminants collected in the contaminant collection chamber 241 from leaking from both ends of the scraper 240 and contaminating the ground. Alternatively, both ends of the scraper 240 can be open structures. When cleaning the scraper 240 is required, the contaminants collected in the contaminant collection chamber 241 can be discharged from both ends of the scraper 240, making it easier to clean the contaminant collection chamber 241. Thus, the contaminant collection chamber 241 can temporarily store the sewage, dust, and other contaminants scraped off by the scraper 240, so that the contaminants can be centrally transferred and treated, reducing the risk of secondary pollution and improving the cleaning efficiency of contaminants. Specifically, in the scraping state, the power mechanism 300 drives the movable cover 200 to descend to a certain height, so that the scraper 240 is close to or in contact with the ground. While the cleaning component 100 completes mopping, the scraper 240 scrapes up the residual sewage and other contaminants on the ground, so that the sewage is collected in the contaminant collection chamber 241.

[0092] It should be noted that the shape of the pollutant collection chamber 241 is not limited in this embodiment. In actual application, the shape of the pollutant collection chamber 241 can be set to any shape that can realize the function of collecting pollutants, such as a square groove, an arc groove, etc.

[0093] Furthermore, in some embodiments, the scraper 240 is detachably connected to the movable shield 200, allowing the scraper 240 to be replaced individually when worn, aged, or heavily contaminated, without replacing the entire movable shield 200, thus reducing maintenance costs and facilitating individual cleaning of the scraper 240. See also Figure 18 and Figure 19 The detachable connection between the scraper 240 and the movable cover 200 can be achieved by providing a snap-fit ​​protrusion 242 on the side of the scraper 240 that connects to the movable cover 200, and a snap-fit ​​groove 260 on the side of the movable cover 200 that connects to the scraper 240. By engaging the snap-fit ​​protrusion 242 with the snap-fit ​​groove 260, the scraper 240 is detachably connected to the edge of the movable cover 200. Of course, other connection methods such as bolts can also be used between the scraper 240 and the movable cover 200, as long as the detachable connection function can be achieved.

[0094] It should be understood that in other alternative embodiments, the scraper 240 may also be connected to the movable mask 200 as an integral structure, for example, the scraper 240 and the movable mask 200 may be integrally formed, so that the scraper 240 and the movable mask 200 have high connection stability.

[0095] See Figure 6 and Figure 8 In some embodiments, the movable shield 200 rotates around the cleaning component 100 under the action of the power mechanism 300. In this embodiment, the movable shield 200 switches between different states by rotating around the cleaning component 100, so that the movable shield 200 is adapted to the rolling mode of the cleaning component 100, which helps to reduce the space occupied by the movable shield 200, improve the compactness of the cleaning structure 10, and facilitate its application in miniaturized cleaning equipment 1.

[0096] Furthermore, the cleaning component 100 includes a cleaning mop and / or a roller brush. The cleaning mop is absorbent and can clean up sewage and other contaminants on the floor, while the roller brush can remove hair, dust, and other contaminants. Addressing the issues of secondary contamination from dripping water in the mop form and dust shedding in the roller brush form, the cleaning structure 10 of this embodiment uses a movable shield 200 to form a barrier, effectively preventing water dripping and dust shedding from the cleaning component 100 from contaminating the surface to be cleaned. Simultaneously, the scraper 240 on the movable shield 200 can further clean the surface, ensuring a better cleaning effect.

[0097] For ease of understanding, the following embodiments will be described using the example of a cleaning component 100 including a cleaning mop.

[0098] Furthermore, in some embodiments, when the cleaning component 100 is rotatably connected to the housing 20, allowing the cleaning component 100 to rotate relative to the housing 20, the power source driving the rotation of the cleaning component 100 can be the power mechanism 300 or a separate drive component. For example, when the power mechanism 300 drives both the rotation of the cleaning component 100 and the movement of the movable cover 200, the power mechanism 300 can switch power via a power transmission mechanism such as a clutch structure to achieve separate control of the cleaning component 100 and the movable cover 200, thereby saving costs and improving space utilization. As another example, when the cleaning component 100 is driven to rotate by a separate drive component such as a motor, the drive control is more flexible and more stable.

[0099] In some embodiments, the cleaning component 100 has a first axis of rotation along its length, and the movable shield 200 has an arcuate structure with a second axis of rotation. The second axis of rotation is aligned with, parallel to, or inclined to the first axis of rotation. Furthermore, the movable shield 200 can be used in conjunction with a roller-type cleaning component 100 or a track-type cleaning component 100.

[0100] See Figures 3 to 10 In some embodiments, when the movable shield 200 engages with the roller-type cleaning component 100, the cleaning component 100 is approximately cylindrical in shape and has a first rotation axis L1 along its length. When cleaning the floor, the cleaning component 100 rotates around the first rotation axis L1. The movable shield 200 has an arc-shaped structure that conforms to the outline of the cleaning component 100, allowing it to cover and surround the cleaning component 100 in a shielding state, preventing wastewater from dripping onto the floor or being scraped off by obstacles. The arc-shaped structure has a second rotation axis L2, which can coincide with the first rotation axis L1. Therefore, when the power mechanism 300 drives the movable shield 200 to move relative to the cleaning component 100, the movable shield 200 rotates around the second rotation axis L2, which is also the first rotation axis L1. This ensures the stability of the relative position between the movable shield 200 and the cleaning component 100, guaranteeing smooth switching between different states. Of course, the second rotation axis L2 and the first rotation axis L1 can also be set parallel or inclined. The inclined setting means that the second rotation axis L2 and the first rotation axis L1 have an angle. In this case, the power mechanism 300 can also drive the movable cover 200 to move relative to the cleaning component 100 to ensure that the movable cover 200 can switch smoothly between different states.

[0101] See Figure 16 and Figure 17In some embodiments, when the movable shield 200 engages with the tracked cleaning component 100, the cleaning component 100 has a generally flat shape and has two first axes of rotation L1' along its length. See also... Figure 17 As can be seen from the end of the cleaning component 100, two first rotation axes L1' are spaced apart along the forward and backward directions of the cleaning component 100. When cleaning the ground, the cleaning component 100 rotates around the two first rotation axes L1' to form a track-like movement. The movable shield 200 has an arc-shaped structure with a second rotation axis L2, which can be arranged parallel to the first rotation axis L1'. Thus, when the power mechanism 300 drives the movable shield 200 to move relative to the cleaning component 100, the movable shield 200 rotates around the second rotation axis L2. Since the second rotation axis L2 is parallel to the first rotation axis L1', the stability of the relative position between the movable shield 200 and the cleaning component 100 can be ensured, and the movable shield 200 can be smoothly switched between different states. Of course, the second rotation axis L2 can also be set to coincide with or be tilted to the first rotation axis L1. Accordingly, the movable mask 200 is set to a size that is compatible with the cleaning component 100 to ensure that the movable mask 200 can move relative to the cleaning component 100, thereby smoothly switching between different states.

[0102] See Figure 9 and Figure 10 In some embodiments, the scraper 240 is arranged along a straight line parallel to the second rotation axis L2. When the scraper 240 moves with the movable shield 200 to the scraping state, the scraper 240 can simultaneously scrape the surface to be cleaned in the corresponding area of ​​the cleaning component 100, avoiding cleaning dead corners and improving the overall cleaning effect.

[0103] See Figure 3 and Figure 4 , Figure 9 and Figure 10In some embodiments, the movable shield 200 has a first end 210 and a second end 220 opposite to each other. The first end 210 is slidably connected to the cleaning component 100, and the second end 220 is connected to the power mechanism 300. When the power mechanism 300 drives the movable shield 200 to move as a whole through the second end 220, the first end 210 of the movable shield 200 slides relative to the cleaning component 100, thereby providing support for both ends of the movable shield 200 respectively. This makes the force on the movable shield 200 more even during rotation, reducing swaying or offset, and ensuring that the movable shield 200 moves and rotates smoothly. Optionally, in other embodiments, the power mechanism 300 may also be directly connected to the first end 210 of the movable shield 200, thereby driving the movable shield 200 to move as a whole through the first end 210; or, the power mechanism 300 may also be connected to both the first end 210 and the second end 220 of the movable shield 200 simultaneously, which can also drive the movable shield 200 to move as a whole.

[0104] Optionally, referring to Figures 5(a) and 5(b), in some embodiments, the first end 210 of the movable shield 200 is provided with an arc-shaped protrusion 211, which has an arc-shaped structure and protrudes from the end face of the first end 210 of the movable shield 200. The end of the cleaning component 100 is provided with an arc-shaped groove 111 that mates with the arc-shaped protrusion 211. The arc-shaped protrusion 211 can be inserted into the arc-shaped groove 111 and slide along the arc-shaped groove 111, so that the movable shield 200 is slidably connected to the cleaning component 100 through the arc-shaped protrusion 211 and the arc-shaped groove 111. The sliding engagement of the arc-shaped protrusion 211 and the arc-shaped groove 111 provides guidance for the rotation of the movable shield 200, ensuring that the movable shield 200 rotates smoothly around the cleaning component 100, avoiding deviation of the movable shield 200, and improving the accuracy of the state switching of the movable shield 200.

[0105] Of course, in other optional embodiments, the first end 210 of the movable mask 200 is provided with an arc-shaped groove, and the end of the cleaning component 100 is provided with an arc-shaped protrusion that cooperates with the arc-shaped groove, so that the movable mask 200 and the cleaning component 100 can also be slidably connected.

[0106] Furthermore, in some embodiments, the second end 220 of the movable cover 200 is detachably connected to the power mechanism 300. For example, the second end 220 of the movable cover 200 and the power mechanism 300 can be detachably connected by bolts, snap-fit ​​connections, or other similar methods. Therefore, the movable cover 200 can be easily removed from the power mechanism 300 when cleaning, maintenance, or replacement is required, improving maintenance convenience and facilitating separate cleaning of the movable cover 200.

[0107] In some embodiments, the movable shield 200 is provided with at least one reinforcing rib 230, which is disposed on the inner side of the movable shield 200 along the circumferential and / or axial direction. For example, see Figure 10 and Figure 18 The movable shield 200 has multiple reinforcing ribs 230 on its inner side. These ribs extend along both the circumferential and axial directions of the movable shield 200, with the axial direction being the extension direction of the second rotation axis L2. The reinforcing ribs 230 enhance the structural strength of the movable shield 200, preventing deformation under stress when the shield 200 drives the scraper 240 to scrape dirt, thus extending its service life.

[0108] See Figure 3 and Figure 4 , Figure 6 and Figure 8 , Figures 11 to 13 In some embodiments, the cleaning component 100 includes a mop housing 110 and a mop body 120, the mop body 120 being rotatably disposed within the mop housing 110. Specifically, the mop body 120 can be a roller mop or a tracked mop to adapt to different types of cleaning needs. The mop body 120 is driven by an independent drive motor, enabling it to rotate around a first rotation axis L1 to achieve the function of cleaning the floor.

[0109] Furthermore, the power mechanism 300 includes a drive component 310, a first transmission component 320, a second transmission component 330, and a support shaft 340. The drive component 310 provides power; for example, the drive component 310 can be driven by a motor, a cylinder, or a hydraulic system. In this embodiment, a motor drive is used as an example. The drive component 310 and the first transmission component 320 are mounted on the mop housing 110. The drive component 310 is driven by the second transmission component 330 via the first transmission component 320. The support shaft 340 is mounted at the end of the mop body 120. Both ends of the support shaft 340 are connected to the mop housing 110 and the first transmission component 320, respectively. The second transmission component 330 is rotatably mounted on the support shaft 340 and connected to the movable cover 200. The support shaft 340 provides stable rotational support for the second transmission component 330, enabling the drive component 310 to drive the second transmission component 330 to rotate via the first transmission component 320, thereby driving the movable shield 200 to rotate relative to the cleaning component 100, ensuring the reliability of power transmission.

[0110] Optionally, see Figures 11 to 15In some embodiments, the mop housing 110 has a first fixed shaft 113 at its end, and the inner wall of the first transmission component 320 has a second fixed shaft 324. The two ends of the support shaft 340 are respectively sleeved on the first fixed shaft 113 and the second fixed shaft 324 to fix the support shaft 340. Of course, in other embodiments, the support shaft 340 can also be configured to be connected to the first fixed shaft 113 and the second fixed shaft 324 as a whole, that is, the three together form a rotating shaft and are directly fixed to the inner wall of the first transmission component 320, or directly fixed to the end of the mop housing 110.

[0111] For example, the operation of the power mechanism 300 driving the active shield 200 in different working states is as follows:

[0112] When the movable shield 200 needs to switch to the blocking state, the drive component 310 starts working, transmitting power through the first transmission component 320 and the second transmission component 330, causing the movable shield 200 to begin rotating and descending around the cleaning component 100. By controlling the drive component 310 to work for a fixed period of time and then stop, the movable shield 200 can be lowered to a fixed position. For example, if the movable shield 200 is initially in the retracted state, and is located diagonally above the cleaning component 100, then the movable shield 200 can be controlled to rotate and descend 120°, moving it between the cleaning component 100 and the ground, where the movable shield 200 is in the blocking state. It should be understood that the above rotation angle is only an example; depending on actual needs, the rotation and descent angle of the movable shield 200 can also be 60°, 80°, 100°, 110°, 130°, 140°, or other reasonable angles.

[0113] When the movable cover 200 needs to be switched to the retracted state, the steps above are reversed. By controlling the drive component 310 to reverse and stop operating after a fixed time, the movable cover 200 can be rotated 120° in the opposite direction and raised to a fixed position, so that the movable cover 200 is in the retracted state.

[0114] When the movable mask 200 needs to switch to the scraping state, the drive component 310 starts working, transmitting power through the first transmission component 320 and the second transmission component 330, causing the movable mask 200 to rotate and descend around the cleaning component 100. By controlling the drive component 310 to work for a fixed period of time and then stop, the movable mask 200 can be lowered to a fixed position. For example, if the movable mask 200 is initially in the retracted state, and is located diagonally above the cleaning component 100, then the movable mask 200 can be controlled to rotate and descend by 30°. At this time, the scraper on the movable mask 200 is near the ground, and the movable mask 200 is in the scraping state. It should be understood that the above rotation angle is only an example. Depending on actual needs, the rotation and descent angle of the movable mask 200 can also be other reasonable angles such as 10°, 20°, 40°, and 50°.

[0115] Furthermore, since the active mask 200 needs to switch between multiple working states, in order to ensure that the active mask 200 can accurately stop at the predetermined position, the active mask 200 can also be mechanically limited.

[0116] See Figure 9 , Figure 11 and Figure 13 In some embodiments, the second transmission component 330 includes a transmission body 331 and a limiting protrusion 332. The transmission body 331 is disposed at the end of the mop body 120 and is rotatably sleeved on the support shaft 340 and connected to the movable cover 200. The limiting protrusion 332 is connected to the side of the transmission body 331 away from the mop body 120. The first transmission component 320 is transmissionally connected to the transmission body 331. The driving component 310 can drive the transmission body 331 to rotate around the support shaft 340 through the first transmission component 320, thereby causing the movable cover 200 to rotate relative to the cleaning component 100. The first transmission component 320 has a first stop 3211, which is located on the rotation path of the transmission body 331 and is used to cooperate with the limiting protrusion 332 on the transmission body 331 to block the rotation of the transmission body 331, thereby blocking and limiting the movable cover 200.

[0117] Specifically, when it is not necessary to use the movable shield 200 for shielding or the scraper 240 for removing contaminants, the power mechanism 300 can be used to move the movable shield 200 and the scraper 240 away from the ground, so that the movable shield 200 is in a retracted state, preventing the movable shield 200 and the scraper 240 from scraping the ground. When the movable shield 200 rotates and rises until the limiting protrusion 332 abuts against the first stop 3211 of the first transmission component 320, the limiting protrusion 332 and the first stop 3211 cooperate to limit the transmission body 331, stopping the movement of the movable shield 200. At the same time, the drive component 310 cannot continue to drive, causing the current of the drive component 310, such as the motor, to exceed the limit, thereby controlling the drive component 310 to stop operating, ensuring that the movable shield 200 is in a retracted state.

[0118] See Figure 13 In some embodiments, the first transmission component 320 further includes a second stop 3212. The first stop 3211 and the second stop 3212 are spaced apart circumferentially along the support shaft 340, and the limiting protrusion 332 is located between the first stop 3211 and the second stop 3212. When the movable shield 200 needs to switch to the shielded state, the driving component 310 drives the movable shield 200 to rotate and descend until the limiting protrusion 332 abuts against the second stop 3212. At this time, the limiting protrusion 332 and the second stop 3212 cooperate to limit the transmission body 331, causing the movable shield 200 to stop moving. At the same time, the driving component 310 cannot continue to drive, causing the current of the driving component 310, such as the motor, to exceed the limit, thereby controlling the driving component 310 to stop operating and ensuring that the movable shield 200 is in the shielded state.

[0119] Therefore, by the limiting protrusion 332 abutting against the first stop 3211 and the second stop 3212 to form a mechanical limit, the maximum rotation angle of the movable cover 200 can be precisely limited, ensuring that the movable cover 200 can switch stably between different working states, and also preventing the movable cover 200 from colliding with the cleaning component 100 or other components due to excessive rotation.

[0120] Furthermore, during the rotation and lifting of the movable cover 200, it may become stuck due to foreign objects and be unable to move. This would prevent the second transmission component 330, the first transmission component 320, and the drive component 310 from operating, causing the current of the drive component 310, such as the motor, to exceed its limit. In this case, the cleaning device 1 may mistakenly identify that the movable cover 200 has been raised to its position and then control the cleaning component 100 and the movable cover 200 to descend and perform cleaning operations via the lifting drive component, resulting in the movable cover 200 scratching the floor. Therefore, to avoid the above problems, the power structure can be further optimized.

[0121] See Figure 9 , Figure 11and Figure 13 In some embodiments, the power mechanism 300 further includes a first switch (not shown in the figure). The first transmission component 320 is provided with a switch mounting groove 323, and the first switch is disposed on the first transmission component 320. For example, the first switch can be a micro switch, a push-button switch, etc., and the first switch is fixed in the switch mounting groove 323 by a snap-fit. The first switch is electrically connected to the drive component 310 through a wiring harness and is used to control the opening or closing of the drive component 310. The transmission body 331 is provided with a switch protrusion 333, which protrudes from the side of the transmission body 331 away from the cleaning component 100, and is used to cooperate with the first switch to stop the drive component 310 from driving and to retract the movable cover 200. Specifically, when the movable cover 200 needs to be switched to the retracted state, the drive component 310 starts to work, and is driven by the first transmission component 320 and the second transmission component 330 to make the movable cover 200 rotate and rise around the cleaning component 100. If the movable cover 200 is blocked by a foreign object during its rotation and rise, preventing the drive component 310 from operating, even if the current of the drive component 310 exceeds its limit, the cleaning device 1 will not control the lifting drive to lower the cleaning component 100 and the movable cover 200 because the first switch has not been triggered. In other words, only when the movable cover 200 rotates and rises to the point where the first switch is triggered, indicating that the movable cover 200 will not pose a risk of scratching the floor, can the lifting drive be used to lower the cleaning component 100 and the movable cover 200 for cleaning operations.

[0122] Optionally, in some embodiments, the power mechanism 300 further includes a second switch, which is disposed on the first transmission component 320 and located near the second stop block 3212. The first and second switches are spaced apart circumferentially along the support shaft 340. The second switch is electrically connected to the drive component 310, and the switch protrusion 333 is located between the first and second switches. When the movable shield 200 needs to switch to the blocking state, the drive component 310 drives the movable shield 200 to rotate and descend until the switch protrusion 333 abuts against the second switch. At this time, the second switch is triggered to close the drive component 310, causing the movable shield 200 to stop moving and be in the blocking state. The second switch and the switch protrusion 333 cooperate to provide electrical limit, which can effectively ensure that the movable shield 200 can accurately stop at a preset position when in the blocking state, ensuring the reliability of the blocking.

[0123] Furthermore, the transmission method between the drive component 310 and the first transmission component 320 and the second transmission component 330 can be a gear drive, belt drive, linkage drive, or other similar transmission methods. For ease of understanding, the following embodiments will use a gear drive as an example.

[0124] See Figure 11 and Figure 13In some embodiments, the transmission body 331 is provided with a transmission gear 334, which is integrally connected to the transmission body 331 and rotatably mounted on the support shaft 340 along with the transmission body 331. The first transmission component 320 includes a transmission housing 321 and a gear set 322. The transmission housing 321 is connected to the mop housing 110, for example, by bolts. The gear set 322 is connected to the transmission housing 321 and meshes with the drive component 310 and the transmission gear 334. For example, the gear set 322 includes three sequentially meshing gears, which are rotatably disposed within the transmission housing 321. Of course, the number of gears in the gear set 322 is not limited to three; for example, in other embodiments, the gear set 322 may have two, four, five, or more gears. The drive component 310 and the transmission body 331 are connected by gear transmission, which can flexibly realize speed change, and the transmission accuracy and efficiency are high. It can stably transmit the power of the drive component 310 to the transmission body 331, thereby ensuring the smooth rotation of the movable cover 200.

[0125] See Figure 9 and Figure 11 In some embodiments, the edge of the transmission body 331 extends toward the mop body 120 and is provided with a connecting strip 335, which fits against the outer surface of the movable cover 200. For example, the connecting strip 335 can be configured as an arc-shaped elongated structure that cooperates with the movable cover 200. When the transmission body 331 is connected to the second end 220 of the movable cover 200, the connecting strip 335 can fit against the outer surface of the second end 220 of the movable cover 200, which facilitates connection and positioning, and also enhances the connection strength between the transmission body 331 and the movable cover 200, making the movable cover 200 less prone to loosening or deformation under force, and improving the stability of the overall structure.

[0126] Furthermore, in some embodiments, the drive component 310, the first transmission component 320, and the second transmission component 330 are disposed at the same end of the mop body 120. For example, see [reference needed]. Figure 3 and Figure 4 The drive component 310, the first transmission component 320, and the second transmission component 330 are all located at the second end 220 near the movable cover 200, which helps to simplify the transmission structure layout and reduce assembly complexity.

[0127] In some embodiments, the mop housing 110 is provided with a connecting rod 112 for connecting an external lifting drive. See also Figure 3The top of the mop housing 110 is provided with two connecting rods 112. The connecting rods 112 facilitate the connection between the cleaning structure 10 and the lifting drive component to achieve the overall lifting of the cleaning structure 10. Of course, the number of connecting rods 112 is not limited to two. For example, the number of connecting rods 112 can also be one, three, four or more.

[0128] In some embodiments, the length of the movable shield 200 is greater than or equal to the length of the mop body 120. The length of the movable shield 200 refers to its length along the second rotation axis L2, and the length of the mop body 120 refers to its length along the first rotation axis L1. Therefore, when the movable shield 200 is in the shielding state, it can completely cover the mop body 120, effectively preventing contaminant leakage. Similarly, if the length of the scraper 240 is greater than or equal to the length of the mop body 120, then after contaminants on the mop body 120 fall to the ground, the scraper 240 can scrape away as much contaminant as possible, ensuring effective cleaning.

[0129] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0130] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
