Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a cleaning device. Background Technology

[0002] Cleaning devices can assist people in cleaning surfaces or replace manual cleaning, saving labor and improving cleaning efficiency. As a result, there is an increasing variety of cleaning devices to meet people's different cleaning needs.

[0003] When cleaning a surface, a significant amount of residue will accumulate on the surface over time. Continuing to clean at this point will reduce the cleaning efficiency. To restore the cleaning efficiency, the surface of the part usually needs to be thoroughly cleaned.

[0004] In the existing technology, the cleaning component is always in contact with the surface of the cleaning component through a matching scraper to ensure its own cleanliness. However, when the cleaning component wants to perform self-cleaning, the scraper blade has a certain obstruction effect and generates a certain amount of noise, which affects the self-cleaning progress of the cleaning component and affects the user experience. Utility Model Content

[0005] In view of this, the present invention proposes a cleaning device that aims to maintain a good cleaning effect for a long time during operation, and to easily achieve self-cleaning with low noise during self-cleaning.

[0006] The cleaning device proposed in this utility model includes: a cleaning component, the cleaning component including a rotatable cleaning element for cleaning a surface to be cleaned; a scraper, the scraper being rotatable between a first position and a second position, the interference between the scraper and the cleaning element in the first position being greater than the interference between the scraper and the cleaning element in the second position; the cleaning element is capable of driving the scraper to rotate, when the cleaning element rotates towards a first direction, the cleaning element drives the scraper to rotate to the first position; when the cleaning element rotates towards a second direction, the cleaning element drives the scraper to rotate to the second position.

[0007] As can be seen from the above technical solution, the cleaning device proposed in this utility model allows the cleaning component to clean the surface to be cleaned after rotating in the first direction. At this time, the cleaning component drives the scraper to rotate to the first position, creating a larger interference between the scraper and the cleaning component. This allows the scraper to clean the surface of the cleaning component while the cleaning component cleans the surface to be cleaned, enabling the cleaning component to maintain a good cleaning effect for a long time. After rotating in the second direction, the cleaning component can perform self-cleaning. At this time, the cleaning component drives the scraper to rotate to the second position, reducing the interference between the scraper and the cleaning component. This reduces the obstruction effect of the scraper on the surface of the cleaning component during self-cleaning, thereby improving the self-cleaning efficiency and reducing noise during self-cleaning.

[0008] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and do not limit the disclosure of the embodiments of this utility model. Attached Figure Description

[0039] In family life, tedious housework consumes a lot of time and energy, and cleaning devices have emerged in response to this need. Some existing cleaning devices, such as floor mops, generally use a rolling roller to mop the surface to be cleaned. During the self-cleaning process of existing floor mops, the scraper remains in contact with the cleaning components, making the self-cleaning process slow and noisy. Removing the scraper to clean the cleaning components is time-consuming, laborious, and complicated.

[0040] In view of this, this application proposes a cleaning device 1000, combined with Figure 1 and Figure 2 As shown, it includes: cleaning component 1 and scraper 4.

[0041] Among them, such as Figure 2 As shown, the cleaning component 1 includes a rotatable cleaning element 11, which is used to clean the surface to be cleaned. The surface to be cleaned can be the ground, that is, the cleaning device 1000 is used to clean the ground; the surface to be cleaned can also be a wall, window or ceiling, that is, the cleaning device 1000 can be used to clean the facade or a high surface.

[0042] Combination Figure 2 and Figure 3As shown, the scraper 4 is rotatable between a first position and a second position. The interference between the scraper 4 and the cleaning component 11 in the first position is greater than that in the second position. That is, the interference between the scraper 4 and the cleaning component 11 is larger in the first position; for example, the scraper 4 can press firmly against the surface of the cleaning component 11, even causing the surface of the cleaning component 11 to be concave to a certain extent. In the second position, the interference between the scraper 4 and the cleaning component 11 is smaller; the scraper 4 experiences reduced force, and the force between the scraper 4 and the cleaning component 11 is smaller.

[0043] The cleaning component 11 can drive the scraper 4 to rotate. When the cleaning component 11 rotates in the first direction, such as Figure 2 and Figure 4 As shown, the cleaning component 11 drives the scraper 4 to rotate to the first position; when the cleaning component 11 rotates in the second direction, as... Figure 3 and Figure 5 As shown, the cleaning component 11 drives the scraper 4 to rotate to the second position. The cleaning component 11 of this application can be a passive rolling cleaning component or an active rotating cleaning component driven by a motor; regardless of whether the cleaning component 11 rotates in the first direction or the second direction, it can drive the scraper 4 to rotate and switch positions, thereby changing the amount of interference between the scraper 4 and the cleaning component 11.

[0044] As can be seen from the above, in the cleaning device 1000 proposed by this utility model, after the cleaning component 11 rotates in the first direction, the cleaning component 11 can clean the surface to be cleaned. At this time, the cleaning component 11 drives the scraper 4 to rotate to the first position, so that a large amount of interference is generated between the scraper 4 and the cleaning component 11. Thus, while the cleaning component 11 cleans the surface to be cleaned, the scraper 4 can clean the surface of the cleaning component 11 to a certain extent. For example, it can scrape off the dirt and dust attached to the surface of the cleaning component 11. When the cleaning component 11 is cleaned by the scraper 4 and then rotates back to clean the surface to be cleaned, the cleaning ability is improved to a certain extent. Therefore, the scraper 4 set in the first position can enable the cleaning component 11 to maintain a good cleaning effect for a long time and improve the cleaning effect on the surface to be cleaned.

[0045] After the cleaning component 11 rotates in the second direction, it can perform self-cleaning. At this time, the cleaning component 11 drives the scraper 4 to rotate to the second position, which reduces the amount of interference between the scraper 4 and the cleaning component 11. As a result, the scraper 4 reduces its obstruction effect on the surface of the cleaning component 11 when it performs self-cleaning, which allows the cleaning component 11 to rotate faster for self-cleaning, thereby improving the self-cleaning efficiency of the cleaning component 11 and reducing the noise during self-cleaning.

[0046] In this application, the cleaning component 11 can be manually pushed to move relative to the surface to be cleaned for cleaning. The rotation of the cleaning component 11 can also drive the scraper 4 to rotate and change its position, and change the amount of interference between the scraper 4 and the cleaning component 11. The whole process does not require an additional power device, thereby saving costs, saving the installation space inside the cleaning device 1000, and simplifying operation.

[0047] It should be noted that, in this application, when the cleaning component 11 rotates counterclockwise in the first direction, it rotates clockwise in the second direction. In other examples, when the cleaning component 11 rotates clockwise in the first direction, it rotates counterclockwise in the second direction.

[0048] Understandably, compared to the self-cleaning process of mops in related technologies, where the scraper abuts against the cleaning component during self-cleaning, resulting in a slower self-cleaning process and noise, the cleaning component 11 in this application experiences reduced force from the scraper 4 during self-cleaning. This minimizes the interference between the scraper 4 and the cleaning component 11, resulting in a smaller force exerted by the scraper 4 on the cleaning component 11. Consequently, the cleaning component 11 experiences less resistance and can rotate smoothly during the self-cleaning process, achieving high self-cleaning efficiency and low noise.

[0049] Compared to the time-consuming and labor-intensive process of disassembling the scraper and cleaning the cleaning component in related technologies, the cleaning component 11 in this application can rotate the scraper 4 when switching from the cleaning working mode (the cleaning component 11 rotates in the first direction) to the self-cleaning mode (the cleaning component 11 rotates in the second direction), thereby changing the position of the scraper 4 and thus changing the amount of interference between the scraper 4 and the cleaning component 11. As a result, the cleaning component 11 of this application is not interfered with by the scraper 4 during self-cleaning. The whole process is simple to operate and saves time and manpower.

[0050] In some embodiments of this application, the cleaning element 11 can be made of an absorbent material. Of course, to improve the cleaning effect, the cleaning element 11 can also include a multi-layered structure, such as a lint layer. When the cleaning element 11 includes a lint layer, the interference between the scraper 4 and the cleaning element 11 is greater than or equal to 5% of the lint layer thickness and less than or equal to 80% of the lint layer thickness, such as 5%, 10%, 20%, 30%, 50%, 70%, or 80%. It should be noted that the lint layer can be dry or wet; the interference can be understood as the depth to which the scraper 4 contacts the lint layer when it is dry. By setting an appropriate interference, even when the lint layer is wetted, the scraper 4 can still maintain a certain level of contact when in the first position, thereby improving the cleanliness of the cleaning element 11. The interference can also be understood as the portion where the scraper 4 and the cleaning element 11 intersect or overlap.

[0051] When the scraper 4 is in the first position, the interference between the scraper 4 and the cleaning component 11 (when the pile layer is dry) can be greater than or equal to 50% and less than or equal to 80% of the pile layer thickness, for example, it can be 50%, 60%, 70%, or 80%. When the scraper 4 is in the second position, assuming that the thickness of the pile layer decreases by more than or equal to 30% after absorbing water, the interference between the scraper 4 and the cleaning component 11 (when the pile layer is dry) can be greater than or equal to 5% and less than or equal to 30% of the pile layer thickness. Then, when the pile layer has fully absorbed water, the scraper 4 in the second position will just be in contact with the surface of the cleaning component 11 or will not be in contact. Thus, when the scraper 4 is in the second position, the cleaning component 11 can perform self-cleaning without the resistance of the scraper 4, improving the cleaning effect of the cleaning component 11.

[0052] In some embodiments of this application, at the first position, such as Figure 2 and Figure 4 As shown, the scraper 4 abuts against the cleaning component 11, resulting in a large interference fit between them. The scraper 4 provides scraping force to the cleaning component 11, thus facilitating the removal of contaminants and other pollutants from its surface. In the second position, as... Figure 3 and Figure 5 As shown, the scraper 4 is in contact or clearance fit with the cleaning component 11. Therefore, the force between the scraper 4 and the cleaning component 11 is relatively small, preventing the scraper 4 from interfering with the self-cleaning process of the cleaning component 11. To ensure the scraper 4 rotates quickly following the rotation of the cleaning component 11 when switching from self-cleaning mode to cleaning mode, the scraper 4 in the second position can be manually rotated to contact the surface of the cleaning component 11, and then the cleaning component 11 can be rotated along the first direction, causing the scraper 4 to rotate accordingly. Alternatively, the scraper 4 can be rotated without manual operation. After the cleaning component 11 has rotated along the first direction for a certain period, and a certain size of object to be cleaned adheres to its surface, the object contacts the scraper 4, causing the scraper 4 to rotate to the first position. At this point, the scraper 4 contacts the surface of the cleaning component 11 and scrapes away the object.

[0053] In some embodiments of this application, such as Figure 2 and Figure 3As shown, the cleaning component 1 also includes a first roller 12 and a second roller 13. The cleaning component 11 includes an annular cleaning belt. The first roller 12 and the second roller 13 are spaced apart, with the second roller 13 positioned near the scraper 4. The annular cleaning belt rotatably wraps around the first roller 12 and the second roller 13. In these embodiments, the annular cleaning belt can be supported by the first roller 12 and the second roller 13, thereby improving the tension of the annular cleaning belt. The first roller 12 and the second roller 13 can rotate around a rotation axis, making it easier for the annular cleaning belt supported by the first roller 12 and the second roller 13 to rotate, thus reducing the effort required for cleaning. After the annular cleaning belt is tensioned by the first roller 12 and the second roller 13, the length of the cleaning component 11 is increased, effectively increasing the contact area between the annular cleaning belt and the surface to be cleaned. This allows the annular cleaning belt to fully adhere to and transport debris, improving the cleaning effect of the cleaning component 11.

[0054] It should be noted that the waste described in this application includes both shaped solid waste, such as crumpled paper and fruit peels, and flowing liquid waste, such as sewage; solid waste can also contain liquid, such as soaked paper towels, etc. This waste has shape and can be picked up.

[0055] Furthermore, such as Figure 4 As shown, in the first position, the end of the scraper 4 points towards the rotational axis of the second roller 13. In these embodiments, with the scraper 4 directly pointing towards the rotational axis of the second roller 13, the stopping effect between the scraper 4 and the annular cleaning belt is optimal, the fit between the scraper 4 and the annular cleaning belt remains stable, and a larger interference fit can be achieved, which is beneficial for the scraper 4 to clean the surface of the annular cleaning belt of debris, hair, etc. In the second position, as... Figure 5 As shown, the plane containing the scraper 4 forms an angle with the rotational axis of the second roller 13. Therefore, in these embodiments, the scraper 4 is in a depressurized state, the cooperation between the scraper 4 and the annular cleaning belt is low, and the annular cleaning belt can rotate rapidly along the second direction for self-cleaning.

[0056] In some embodiments of this application, such as Figure 2 and Figure 3As shown, the second roller 13 is positioned above the first roller 12. The distance between the second roller 13 and the surface to be cleaned can be greater than the distance between the first roller 12 and the surface to be cleaned; for example, the distance from the axis of the second roller 13 to the surface to be cleaned is greater than the distance from the axis of the first roller 12 to the surface to be cleaned. Alternatively, the second roller 13 can be positioned above the first roller 12, with the height of the second roller 13 corresponding to the highest point of the surface to be cleaned being greater than the height of the first roller 12 corresponding to the highest point of the surface to be cleaned. Therefore, when the annular cleaning belt is positioned on the first roller 12 and the second roller 13 at the aforementioned relative positions, the annular cleaning belt will form a cleaning end 115 (the cleaning end 115 can be referenced) in a specific area relative to the surface to be cleaned. Figure 2 ).

[0057] In some further embodiments of this application, such as Figure 2 and Figure 3 As shown, the first roller 12 is used to press a portion of the annular cleaning belt against the surface to be cleaned to form a cleaning end 115. The second roller 13 is located obliquely above the first roller 12, so that the annular cleaning belt forms an inclined conveying side 111. The inclined conveying side 111 can extend obliquely from the portion near the surface to be cleaned toward the front-upper or rear-upper part of the cleaning device 1000. When the cleaning end 115 contacts the debris on the surface to be cleaned, the cleaning member 1 can automatically adjust the gap between the cleaning end 115 and the surface to be cleaned based on the size of the debris. In practical applications, when the cleaning device 1000 is cleaning the surface to be cleaned, if it encounters large pieces of debris, the debris will press against the cleaning end 115 and lift the cleaning component 1 as a whole. This allows the larger debris to be conveyed through the conveying side 111 (for example, the conveying side 111 itself can hold the debris; or the conveying side 111 can cooperate with the cavity wall of the mounting cavity 91 in the body 9 to hold the debris; or the conveying side 111 can cooperate with the cleaning auxiliary component 2 described later to hold the debris). This allows the cleaning component 1 to automatically adjust the gap between itself and the surface to be cleaned according to the size of the debris, enabling the cleaning device 1000 to remove debris of varying sizes. Figure 2 , Figure 3 and Figure 8 As shown, the angle between the inclined conveyor side 111 and the surface to be cleaned is less than 90 degrees and greater than 0 degrees, which reduces the space required parallel to the surface to be cleaned when the annular cleaning belt cleans the surface to be cleaned; and the inclined conveyor side 111 can also more easily form contact with the scraper 4 after the garbage is attached to the surface, so as to remove the garbage; the conveyor side 111 can better convey garbage.

[0058] In some embodiments, the conveying side 111 has a certain deformation capability, and can deform when squeezed by garbage, thereby achieving adjustable gap between it and the conveying ramp 22.

[0059] In some embodiments, such as Figure 2 and Figure 3 As shown, the cleaning device 1000 also includes a cleaning auxiliary component 2, which is positioned behind the cleaning component 1 along the forward direction of the cleaning device 1000. The cleaning auxiliary component 2 assists the annular cleaning belt in cleaning waste. When the cleaning component 11 rotates, it can carry the waste on the surface to be cleaned under the action of friction, and with the assistance of the cleaning auxiliary component 2, it cooperates with the conveying side 111 to pick up and convey the waste, thereby enabling the cleaning of some solid waste. The conveying side 111, by cooperating with the cleaning auxiliary component 2 to clamp and convey the waste along the movement direction of the conveying side 111, can raise the height of waste conveying. During the waste conveying process, it can avoid relying on wind power to drive the suction of waste, thus eliminating the need for a high-speed fan to suck up the waste, thereby helping to reduce the noise and power consumption of the cleaning device 1000.

[0060] In other examples, the fan can also be configured to operate together with cleaning component 1 and cleaning auxiliary component 2 to improve waste conveying and cleaning efficiency.

[0061] It should also be noted that the forward direction of the cleaning device 1000 is its primary direction of movement during operation. For example, if the cleaning device 1000 is a handheld device and the surface to be cleaned is the ground, the user needs to hold the cleaning device 1000 and push it in the direction the user is moving forward; this direction is the forward direction of the cleaning device 1000. In other embodiments, if the cleaning device 1000 is a cleaning robot, then its forward direction is the primary direction of movement for the cleaning robot.

[0062] In an optional embodiment, the cleaning component 1 is inclined relative to the surface to be cleaned, and the cleaning auxiliary component 2 is disposed diagonally below or above the cleaning component 1 along the forward direction of the cleaning device 1000.

[0063] Among them, such as Figure 2 and Figure 3 As shown, the cleaning auxiliary component 2 is positioned diagonally below the cleaning component 1 along the forward direction of the cleaning device 1000. The outer surface of the upper diagonal of the cleaning auxiliary component 2 cooperates with the conveying side 111 of the cleaning component 11. When the cleaning component 11 rotates in the first direction, the cleaning end 115 squeezes the garbage onto the surface of the cleaning component 11. The conveying side 111 then cooperates with the cleaning auxiliary component 2 to pick up the garbage. Under the rotation of the cleaning component 11, the garbage is conveyed along the upper diagonal of the outer surface of the cleaning auxiliary component 2 to the scraper 4 for scraping.

[0064] Among them, such as Figure 6As shown, when the cleaning auxiliary component 2 is positioned obliquely above the cleaning component 1 along the forward direction of the cleaning device 1000, the outer surface of the lower oblique part of the cleaning auxiliary component 2 cooperates with the conveying side 111 of the cleaning component 11. When the cleaning component 11 rotates along the first direction, the cleaning end 115 squeezes the garbage onto the surface of the cleaning component 11. The conveying side 111 then cooperates with the cleaning auxiliary component 2 to pick up the garbage, and under the rotation of the cleaning component 11, the garbage is conveyed along the lower oblique part of the outer surface of the cleaning auxiliary component 2 to the scraper 4 for scraping.

[0065] Regardless of the orientation of the cleaning auxiliary component 2 relative to the cleaning component 1, at least a portion of the side of the cleaning auxiliary component 2 facing the cleaning component 11 is positioned opposite the conveying side 111. This allows a portion of the surface of the cleaning auxiliary component 2 to be positioned opposite the conveying side 111 and to clamp and convey the waste. For example, in some specific examples, the surfaces of the conveying side 111 and the cleaning auxiliary component 2 are parallel to each other, thereby improving the uniformity of the gap between them and thus improving the uniformity of the clamping force on the waste, achieving a better clamping effect on the waste.

[0066] In some embodiments of this application, when the surface to be cleaned is the ground or other horizontal surface, the weight of the first roller 12 is greater than the weight of the second roller 13. Therefore, the heavier first roller 12, positioned closer to the ground, allows the cleaning end 115 of the cleaning component 11, which presses against the surface to be cleaned, to adhere more tightly to the surface. This also increases the corresponding friction, including the friction between the cleaning end 115 and the surface to be cleaned, and between the cleaning end 115 and the debris, thereby improving the cleaning effect, especially for small solid particles and stubborn stains on the surface. Simultaneously, the heavier first roller 12 lowers the center of gravity of the entire cleaning component 1, making the cleaning device 1000 more stable when operating on the ground during the cleaning process.

[0067] In a specific embodiment, the weight of the first roller 12 is greater than the weight of the second roller 13. This could be because the weight of the first roller 12 itself is greater than the weight of the second roller 13, or the weight of the first roller 12 and the driving component inside the first roller 12 is greater than the weight of the second roller 13, or the total weight of the first roller 12 and other components such as the counterweight inside the first roller 12 is greater than the weight of the second roller 13. No limitation is imposed here.

[0068] In some embodiments of this utility model, such as Figure 2 and Figure 3As shown, the cleaning device 1000 also includes a body 9, which includes a mounting cavity 91 in which the cleaning component 1 is disposed; and a scraper 4 is rotatably disposed on the inner wall of the mounting cavity 91. By placing the cleaning component 1 and the scraper 4 in the mounting cavity 91 of the body 9, the cleaning component 1 and the scraper 4 are protected and supported by the body 9, forming a functional integral component. This facilitates the movement of the entire cleaning device 1000 and also facilitates the cleaning operation of the cleaning device 1000.

[0069] To facilitate the movement of the cleaning device 1000 and improve its ease of movement, in some embodiments, such as... Figure 1 and Figure 9 As shown, the body 9 also includes a travel wheel 94, which is located at the bottom of the body 9 and directly contacts the surface to be cleaned. The travel wheel 94 reduces the friction when the cleaning device 1000 moves on the surface to be cleaned, thus making the movement of the cleaning device 1000 on the surface to be cleaned smoother. When the cleaning device 1000 is a handheld cleaning device, it makes it easier and less strenuous for the user to push the cleaning device 1000 forward.

[0070] In a specific embodiment, the body 9 is also equipped with a motor to drive the driving wheels 94 to rotate, thereby making the cleaning device 1000 move more effortlessly; or, the body 9 is equipped with multiple driving wheels 94, the body 9 is connected to the hand handle, and each driving wheel 94 is a passive wheel, which is pushed forward by applying force to the hand handle by hand; or, some driving wheels 94 are driven by a motor, and the hand handle is pushed manually at the same time.

[0071] In some further embodiments of this application, such as Figure 4 and Figure 5 As shown, the scraper 4 includes a stop portion 41 and at least one limiting portion 42. The stop portion 41 is rotatably connected to the inner wall of the mounting cavity 91, and at least one limiting portion 42 is provided on the side of the stop portion 41 away from the cleaning component 11. In the first position and / or the second position, the side of the at least one limiting portion 42 away from the cleaning component 11 abuts against the inner wall of the mounting cavity 91. When the limiting portion 42 abuts against the inner wall of the mounting cavity 91, the scraper 4 stops rotating with the cleaning component 11, and the relative position between the stop portion 41 and the cleaning component 11 is determined at this time.

[0072] When the scraper 4 is in the first position, if the limiting part 42 abuts against the cavity wall of the mounting cavity 91, the scraper 4 can apply stable force to the surface of the cleaning part 11 and reliably scrape off the debris.

[0073] When the scraper 4 is in the second position, if the limiting part 42 abuts against the cavity wall of the mounting cavity 91, the size of the gap between the abutting part 41 and the surface of the cleaning part 11 is determined, so that the abutting part 41 can exert little resistance on the cleaning part 11 or not exert any force on the cleaning part 11 during the self-cleaning process of the cleaning part 11 rotating in the second direction; it can also enable the scraper 4 to move from the second position to the first position as soon as possible when the cleaning part 11 starts cleaning operation after the cleaning part 11 changes from the second direction to the first direction when the scraper 4 is in the second position.

[0074] In some embodiments, such as Figure 4 and Figure 5 As shown, the inner wall of the mounting cavity 91 is recessed towards the side away from the cleaning component 11, providing a clearance space 911. A portion of the stop portion 41 is located within the clearance space 911, and at least one limiting portion 42 can abut against the clearance space 911. Therefore, in these examples, the cavity wall of the mounting cavity 91 can be made to closely match the shape of the scraper 4, thereby providing the necessary space for the rotation of the scraper 4 and providing the necessary fitting structure for the limiting portion 42 of the scraper 4 to be positioned. This allows the limiting portion 42 to abut against the wall of the clearance space 911 after the scraper 4 rotates, and the aforementioned clearance space 911 enables a better fit between the mounting cavity 91 and the scraper 4.

[0075] In other embodiments, such as Figure 4 and Figure 5As shown, the limiting part 42 includes a first limiting part 421 and a second limiting part 422. The stop part 41 is provided with the first limiting part 421 and the second limiting part 422 at intervals. In the first position, the side of the first limiting part 421 away from the cleaning member 11 stops against the inner wall of the mounting cavity 91; in the second position, the side of the second limiting part 422 away from the cleaning member 11 stops against the inner wall of the mounting cavity 91. In these embodiments, by providing two types of limiting parts 42 that stop against the inner wall of the mounting cavity 91 at different positions, the relative positional relationship between the scraper 4 and the cleaning member 11 can be confirmed when the scraper 4 is rotated to the first position and the second position. After the first limiting part 421 abuts against the inner wall of the mounting cavity 91, the scraper 4 and the cleaning component 11 can be stably stopped. At this time, the degree of interference fit between the scraper 4 and the cleaning component 11 is certain, so that the scraper 4 can continuously clean the garbage attached to the surface of the cleaning component 11, ensuring good cleaning effect when the cleaning component 11 rotates along the first direction for cleaning. After the second limiting part 422 abuts against the inner wall of the mounting cavity 91, the gap between the scraper 4 and the cleaning component 11 can be certain (or just in contact with the surface of the cleaning component 11). So that during the self-cleaning process of the scraper 4 rotating along the second direction, the scraper 4 can release force and does not generate resistance to the rotation of the cleaning component 11, so that the cleaning component 11 can rotate quickly to achieve self-cleaning; it can also make the scraper 4 rotate from the second position to the first position after the cleaning component 11 switches from the second direction to the first direction, realizing the position switching of the scraper 4 and the cleaning of the garbage attached to the surface of the cleaning component 11 by the scraper 4.

[0076] In some embodiments, combined with Figure 7 and Figure 9 As shown, the scraper 4 has a rotating shaft 43 at each end. The rotating shaft 43 is rotatably connected to the cavity wall of the mounting cavity 91, so that the scraper 4 can rotate stably relative to the mounting cavity 91 and switch stably between the first position and the second position.

[0077] In some embodiments of this application, combined with Figure 1 and Figure 2As shown, the cleaning device 1000 also includes a liquid dispensing component 5, which is used to output cleaning fluid toward the cleaning component 11. The liquid dispensing component 5 is located downstream of the scraper 4 in the direction of rotation of the cleaning component 11. Therefore, the liquid dispensing component 5 of this application can dispense liquid toward the cleaning component 11, ensuring that the cleaning component 11 is sufficiently wetted, thereby improving the cleaning ability of the cleaning component 11 on the surface to be cleaned. Because the liquid dispensing component 5 is located downstream of the scraper 4, the debris and wastewater on the surface of the cleaning component 11 are re-wetted after being cleaned by the scraper 4, allowing the liquid dispensing component 5 to replenish the cleaning fluid to the cleaning component 11 in a timely manner. The newly added cleaning fluid to the cleaning component 11 is cleaner, thus preventing stains from remaining on the surface of the surface to be cleaned when the cleaning component 11 cleans it, resulting in a cleaner finish.

[0078] In a further embodiment, one end of the liquid outlet component 5 is connected to the scraper 4. In this case, the liquid outlet component 5 can rotate together with the scraper 4, thereby enabling the liquid outlet component 5 and the scraper 4 to be linked.

[0079] In some specific embodiments, such as Figure 7 As shown, the liquid dispensing component 5 is provided with a positioning post 51, and the scraper 4 is provided with a positioning hole 45. After the positioning post 51 is positioned in the positioning hole 45, the position of the liquid dispensing component 5 relative to the scraper 4 is relatively stable. In other embodiments, one of the liquid dispensing component 5 and the scraper 4 is provided with a slot and the other with a buckle, thereby realizing the snap-fit ​​cooperation between the liquid dispensing component 5 and the scraper 4; or, the liquid dispensing component 5 and the scraper 4 are provided with corresponding assembly holes, and the two are detachably connected by fasteners.

[0080] In a specific embodiment, when the scraper 4 switches to the second position, such as Figure 5 As shown, the stop part 41 of the scraper 4 moves away from the cleaning part 11, and the liquid outlet part 5 rotates with the scraper 4 to the side close to the cleaning part 11. At this time, the cleaning liquid can also be directly output to the cleaning part 11 through the liquid outlet part 5 to realize the self-cleaning process of the cleaning part 11 continuously rotating in the second direction.

[0081] In this application, the liquid dispensing component 5 can deliver disinfectant to the cleaning component 11, thereby disinfecting the surface to be cleaned by the cleaning component 11; the liquid dispensing component 5 can also deliver cleaning liquid, such as glass cleaner or floor cleaner, to the cleaning component 11, thereby caring for and cleaning the surface to be cleaned by the cleaning component 11.

[0082] In a specific embodiment, the liquid outlet component 5 can also be connected to the liquid storage unit via a hose, thereby enabling the liquid outlet component 5 to continuously outlet liquid for a certain period of time. When the liquid outlet component 5 needs to outlet liquid, the liquid in the liquid storage unit can be pumped into the liquid outlet component 5 by a pump body, and then delivered to the cleaning component 11. In other specific embodiments, the liquid outlet component 5 can also be directly connected to an external pipeline, such as a tap water pipe, to realize the supply of liquid to the liquid outlet component 5 by the tap water pipe.

[0083] In a specific embodiment, the liquid outlet component 5 may have multiple water outlets on the side facing the cleaning component 11, thereby rapidly dispensing liquid to wet the entire cleaning component 11. In possible examples, the water outlets are multiple water outlet holes; in other possible examples, the water outlets are nozzles, which can be adjusted according to the actual situation.

[0084] In some embodiments of this application, such as Figure 1 , Figure 2 , Figure 3 and Figure 9 As shown, the machine body 9 is provided with a cleaning port 92. The cleaning port 92 is located on the machine body 9 near the first roller 12. The cleaning port 92 connects the mounting cavity 91 and the external surface to be cleaned, and a portion of the cleaning component 11 extends into the cleaning port 92. Therefore, by providing the cleaning port 92, not only can the cleaning end 115 of the cleaning component 11 be exposed from the mounting cavity 91 to the outside for cleaning the surface to be cleaned, but the rest of the cleaning component 11 can also be concealed in the mounting cavity 91, improving the aesthetics and integrity of the cleaning device 1000. It also prevents other parts of the cleaning component 11 from accidentally touching the environmental components, protecting the other parts of the cleaning component 11 from impacts, and preventing the environmental components from being accidentally cleaned by other parts of the cleaning component 11.

[0085] In some embodiments of this application, such as Figure 2 and Figure 3 As shown, the body 9 also includes a collection chamber 93, which is connected to the mounting chamber 91. The scraper 4 is disposed on the inner wall of the mounting chamber 91, which is away from the cleaning port 92. In the first position, the scraper 4 scrapes the cleaned material off the cleaning component 11 into the collection chamber 93. This allows the garbage and wastewater scraped off by the scraper 4 to be effectively collected, facilitating the continuous operation of the cleaning device 1000.

[0086] In a specific embodiment, the collection chamber 93 and the installation chamber 91 can be connected by an opening. The opening is located behind the conveying side 111 of the cleaning component 11 and below the position where the scraper 4 abuts against the cleaning component 11, so that the garbage and sewage conveyed from the conveying side 111 can be scraped by the scraper 4 into the installation chamber 91 for collection.

[0087] To facilitate the discharge of garbage and sewage from the collection chamber 93, a recycling container can be added to the collection chamber 93. When garbage and sewage need to be discharged, the recycling container can be directly removed from the collection chamber 93 and then the sewage can be dumped. Alternatively, disposable garbage bags can be added to the collection chamber 93. When the garbage bag is full of garbage and sewage, the garbage bag can be removed and discarded.

[0088] In the embodiment of the inclined arrangement of the cleaning component 11 in this application, the recycling container is located behind and below the conveying side 111. The opening of the recycling container, corresponding to the end of the conveying side 111, can be positioned relatively high, thus increasing the height of the recycling container and expanding its volume to collect more waste and wastewater. In these embodiments, corresponding to the inclined arrangement of the conveying side 111, the opening of the recycling container is also at least partially inclined, allowing the opening to align with the conveying side 111 as closely as possible, better catching falling waste and preventing excessive gaps between the conveying side 111 and the opening of the recycling container, which could cause waste to fall outside the recycling container.

[0089] In some embodiments of this application, such as Figure 2 , Figure 3 and Figure 10 As shown, the first roller 12 is provided with a first groove 121, which is recessed towards the central axis of the first roller 12. By providing the first groove 121 on the first roller 12, when the first roller 12 rotates, since the first roller 12 always supports the annular cleaning belt, when the cleaning end 115 of the annular cleaning belt abuts against the surface to be cleaned, the annular cleaning belt can be recessed towards the first groove 121 under the action of some garbage. The first groove 121 can increase the garbage carrying capacity, so that the annular cleaning belt can better remove garbage from the surface to be cleaned, and it is also convenient for the cleaning device 1000 to collect garbage better. In addition, the first groove 121 of this application can also retain a certain amount of liquid, so that the annular cleaning belt can keep moist, which is conducive to the annular cleaning belt cleaning the surface to be cleaned more thoroughly and is less likely to cause dust during cleaning.

[0090] In some embodiments of this application, the second roller 13 is provided with a second groove (not shown in the figure). The second groove is recessed towards the central axis of the second roller 13. In these embodiments, the second groove on the second roller 13 can provide a certain interference margin when the scraper 4 abuts against the second roller 13. In some cases, it can make the scraper 4 abut against the surface of the second roller 13, or in other cases, it can make the scraper 4 abut against the garbage on the annular cleaning belt on the surface of the second roller 13 more tightly, so as to better scrape off the garbage on the surface of the annular cleaning belt, or better scrape off the sewage on the surface of the annular cleaning belt.

[0091] In some embodiments of this application, such as Figure 2 , Figure 3 and Figure 10As shown, the first roller 12 is provided with a first groove 121, which is recessed inward toward the central axis of the first roller 12, and the second roller 13 is provided with a second groove (not shown), which is recessed inward toward the central axis of the second roller 13. The functions of the first groove 121 and the second groove in these embodiments will not be elaborated here.

[0092] In some embodiments of this application, such as Figure 10 As shown, multiple first grooves 121 are arranged along the axial and / or circumferential directions of the first roller 12. This allows for a greater number of first grooves 121 to be provided on the surface of the first roller 12, and enables the first roller 12 to trap more debris of a certain volume on the surface to be cleaned into the first grooves 121 through the squeezing action of the annular cleaning belt while it abuts against the annular cleaning belt, thus improving the cleaning effect of the annular cleaning belt on the surface to be cleaned. In a further embodiment, multiple first grooves 121 can be accompanied by multiple second grooves (not shown) arranged along the axial and / or circumferential directions of the second roller 13. This allows the scraper 4 to synchronously adjust the amount of interference with multiple areas of the annular cleaning belt on the second roller 13, which is beneficial for the scraper 4 to better remove debris from the surface of the entire annular cleaning belt. After being scraped by the scraper 4, the annular cleaning belt can recover more cleaning power, facilitating the next cleaning operation.

[0093] In some embodiments of this application, such as Figure 10 As shown, the cross-sectional dimensions of the first groove 121 decrease from the opening to the bottom. This allows the waste to be easily embedded into the first groove 121 along with the annular cleaning belt, improves the clamping effect of the first groove 121 on the waste, and prevents the waste from sinking too deep, making it easier for the annular cleaning belt to remove it when it moves to the scraper 4.

[0094] And / or, in some embodiments of this application, the cross-sectional sizes of the openings of the plurality of first grooves 121 are different, thereby adapting to clamping garbage of different shapes and sizes.

[0095] And / or, in some embodiments of this application, when the annular cleaning belt rotates to clean the surface to be cleaned, part of the groove opening of the first groove 121 abuts against the annular cleaning belt. For example, when the cleaning end 115 abuts against the surface to be cleaned, the cleaning end 115 and the debris together recess into the first groove 121, so that the first groove 121 abuts against the annular cleaning belt. For another example, the annular cleaning belt is tensioned on the first roller 12 and the second roller 13, so that the surface of the first roller 12 that contacts the annular cleaning belt forms an abutment. This facilitates the rotation of the annular cleaning belt to the surface to be cleaned, forming the cleaning end 115 that abuts against the surface. The groove wall of the first groove 121 provides a certain supporting force for the annular cleaning belt, and allows the annular cleaning belt to be covered by the debris after being subjected to the reaction force of the debris, and to be recessed into the first groove 121 together with the debris.

[0096] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
