Description

Technical Field

[0001] This disclosure relates to the field of cleaning equipment technology, and specifically to a cleaning device. Background Technology

[0002] With economic development and rising living standards, people have increasingly higher demands for environmental hygiene. To save manpower, a variety of cleaning equipment has emerged on the market, commonly including robotic mopping, robotic sweeping and mopping, floor scrubbers, and handheld cleaning devices. Current technology typically uses cleaning elements such as rollers to clean the work surface. Water can adhere to these cleaning elements, achieving excellent cleaning results.

[0003] When the liquid dispensing assembly supplies cleaning fluid to the cleaning element, the low water pressure at the outlet may prevent the formation of droplets. Instead, a water film may form at or near the outlet, flowing down the wall and causing dripping and leakage. In actual use, droplets and watermarks may remain on the back of the roller, resulting in a poor user experience. Furthermore, after prolonged use, the outlet may become clogged with lint, dust, and other dirt, further exacerbating the dripping and leakage problems. Utility Model Content

[0016] In one embodiment of this disclosure, the cleaning element is configured to extend along a first axis, and a plurality of liquid outlets are provided. The plurality of liquid outlets are distributed along the first axis direction in the liquid outlet assembly and are configured to be located on the movement path of the second cleaning element.

[0051] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present disclosure.

[0052] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this disclosure or its application or use.

[0053] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0054] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0055] In this article, terms such as "up," "down," "front," "back," "left," and "right" are used only to indicate the relative positional relationship between related parts, rather than to define the absolute position of these related parts.

[0056] In this article, "first," "second," etc., are used only to distinguish one another, and not to indicate degree of importance, order, or prerequisite for each other.

[0057] In this document, terms such as “equal” and “same” are not strict mathematical and / or geometric limitations, but also include errors that are understandable to those skilled in the art and permissible in manufacturing or use.

[0058] This disclosure provides a cleaning device, which can be a handheld cleaning device, such as a handheld cleaning machine or handheld floor scrubber, or other handheld cleaning devices well known to those skilled in the art. It can also be a mopping robot, a sweeping and mopping robot, or other self-moving cleaning devices used to clean floors, sofas, carpets, and other work surfaces requiring cleaning. In embodiments where the cleaning device is a handheld floor scrubber, the user can push the scrubber across the floor and use its brush assembly to clean the work surface. In embodiments where the cleaning device is a self-moving cleaning device, the robot moves along a planned path or based on information detected by various sensors on the work surface, completing the cleaning of the work surface.

[0059] refer to Figure 3 This embodiment uses a sweeping and mopping robot as an example of a cleaning device. The cleaning device disclosed herein includes a body 1, cleaning elements 2, and a liquid dispensing assembly 3. The body 1 serves as the basic installation structure for the cleaning device. Wheels are installed on the body 1, enabling the robot to move independently on the work surface. The body 1 also includes a cleaning liquid tank and a wastewater tank. The cleaning liquid tank is used to temporarily store cleaning liquids, such as clean water or disinfectant. The cleaning liquid tank is configured to communicate with the liquid dispensing assembly 3. Figure 5 As shown, the liquid dispensing assembly 3 includes a liquid outlet 31, which is configured to provide cleaning liquid to the cleaning element 2, thereby enabling the cleaning element 2 to perform wet mopping on the work surface. After the cleaning element 2 scrubs the floor, the wastewater on it is scraped into the collection box for storage; alternatively, the body 1 may also be equipped with a suction port, which can be connected to a wastewater tank, so that the cleaning equipment can suck the dirt at the suction port into the wastewater tank for temporary storage.

[0060] Cleaning element 2 is configured for cleaning the work surface; specifically, cleaning element 2 can be a roller or a brush. (Reference) Figures 1 to 3 The cleaning element 2 includes a cleaning element body 20, which is rotatably connected to the body 1. A first cleaning element 21 and a second cleaning element 22 are disposed on the surface of the cleaning element body 20. The first cleaning element 21 and the second cleaning element 22 can be tufted fibers implanted on the surface of the cleaning element body 20, and both can be made of materials with a certain degree of water absorption. When the liquid dispensing assembly 3 provides cleaning liquid to the cleaning element 2, the first cleaning element 21 and the second cleaning element 22 can absorb the cleaning liquid and, as the cleaning element body 20 rotates, perform wet mopping on the working surface, thereby achieving a better cleaning effect.

[0061] When cleaning the working surface, cleaning element 2 will adsorb dirt from the working surface onto the first cleaning element 21 and / or the second cleaning element 22, see [reference]. Figure 3The body 1 also includes a wiper blade 4, which extends along the axial direction of the cleaning element 2 and is configured to squeeze the first cleaning element 21 and the second cleaning element 22 to scrape off dirt adhering to the first cleaning element 21 and / or the second cleaning element 22. Normally, the cleaning element 2 rotates about its own axis under motor control, and the wiper blade 4 is typically positioned behind the cleaning element 2. (Reference) Figure 3 In the view direction, when the cleaning element 2 rotates counterclockwise, after the cleaning element 2 passes over the working surface and cleans the working surface, it can rotate to cooperate with the squeegee 4 to scrape off the dirt.

[0062] The outlet 31 is located on the movement path of the second cleaning component 22, such as Figure 2 As shown, during the water-based cleaning process, at least a portion of the second cleaning element 22 extends radially beyond the first cleaning element 21, and the second cleaning element 22 is configured to intermittently contact the liquid outlet 31 during rotation. Specifically, as... Figure 1 As shown, in the dry state, the dimensions of the first cleaning component 21 and the second cleaning component 22 in the radial direction can be substantially the same, while in the wet state, as... Figure 2 As shown, the flocked fibers typically collapse; however, the second cleaning member 22, even when wet, possesses stronger support than the first cleaning member 21, thereby causing at least a portion of the second cleaning member 22 to extend radially beyond the first cleaning member 21. For example... Figure 4 As shown, since the liquid outlet 31 is located on the movement path of the second cleaning component 22, the second cleaning component 22 can pass through the liquid outlet 31 and come into contact with it during rotation.

[0063] And as it continues to rotate, such as Figure 5 As shown, the second cleaning element 22 can detach from the outlet 31, thereby preventing all the cleaning liquid provided by the outlet 31 from flowing to the second cleaning element 22. Specifically, in one embodiment of this disclosure, during the water-based cleaning process, after the second cleaning element 22 rotates with the cleaning element 2 until it detaches from the outlet 31, the cleaning liquid from the outlet 31 is configured to flow onto the first cleaning element 21. The second cleaning element 22 alternately contacts and detaches from the outlet 31 during rotation. In the contact state, the cleaning liquid can flow to the second cleaning element 22; in the detached state, the cleaning liquid can flow to the first cleaning element 21. Both the first cleaning element 21 and the second cleaning element 22 can be evenly coated with cleaning liquid, thereby ensuring a uniform cleaning effect at all locations on the cleaning element 2.

[0064] This disclosure provides a second cleaning element 22, which, at least in the wetted state, has a relatively larger radial dimension than the first cleaning element 21. The second cleaning element 22 intermittently contacts the liquid outlet 31 as it rotates with the cleaning element body 20. This allows it to puncture the water film formed at the liquid outlet 31 upon contact, preventing the water film from flowing further down the wall and solving the problems of dripping and leakage in the cleaning equipment. Furthermore, the second cleaning element 22 can also wipe and clean the liquid outlet 31 when in contact, reducing or even preventing the outlet 31 from being clogged by lint, dust, or other dirt.

[0065] In one embodiment of this disclosure, the elastic force of the second cleaning member 22 is greater than that of the first cleaning member 21; at least during the water-assisted cleaning process, the second cleaning member 22 is configured to naturally return to a position radially beyond the first cleaning member 21. Further, at least during the water-assisted cleaning process, the second cleaning member 22 is configured to be radially compressed inward under pressure. Under pressure, for example, when rotating to contact the work surface, both the second cleaning member 22 and the first cleaning member 21 are compressed to fit against the work surface under the weight of the cleaning equipment itself, thereby achieving a better cleaning effect; or, when rotating past the squeegee 4, the squeegee 4 can squeeze the first cleaning member 21 and the second cleaning member 22 to scrape off dirt adhering to the first cleaning member 21 and / or the second cleaning member 22.

[0066] When rotated to a state where it is no longer under pressure, the second cleaning component 22, due to its better elasticity, can spring back to its radial dimension; while the first cleaning component 21, due to its relatively poor elasticity and the collapse of fibers caused by water, has a much smaller rebound amplitude than the second cleaning component 22. This ensures that during the water-covered cleaning process, at least part of the second cleaning component 22 extends radially beyond the first cleaning component 21, allowing the second cleaning component 22 to intermittently contact the liquid outlet 31, thereby solving the problems of dripping and leakage in the cleaning equipment.

[0067] In one specific embodiment of this disclosure, the second cleaning element 22 is constructed as a mesh-like woven structure. In this embodiment, different woven structures can be used for the first cleaning element 21 and the second cleaning element 22, resulting in differences in their elastic forces. The mesh-like woven structure has strong dynamic extensibility, forming elastic support through coils or interlaced fiber networks. This structure allows the fibers to deform over a large range under stress and only return to their original shape when the external force is removed. In contrast, traditional flocked fibers have stronger fixation, limiting elastic recovery force. They are prone to instability and collapse under external force, making it difficult to generate the rebound force necessary to restore their radial dimensions.

[0068] In one specific embodiment of this disclosure, the second cleaning component 22 is made of nylon fiber, and the first cleaning component 21 is made of fiber fleece. In this embodiment, different fibers can be used to make the first cleaning component 21 and the second cleaning component 22, resulting in differences in their elasticity. Specifically, the second cleaning component 22 can be made of nylon fiber 900D57F; the first cleaning component 21 can be formed by a mixture of polyester fiber 300D576F and polyester fiber 300D96F. The first cleaning component 21 needs to have good cleaning ability, and it can be made of fiber fleece commonly used in the prior art; while the material selection for the second cleaning component 22 needs to consider both elasticity and cleaning ability. Besides using nylon fiber to make the second cleaning component 22, sponges, mixed fiber materials, etc., can also be used.

[0069] In one embodiment of this disclosure, reference is made to Figure 1 and Figure 2 On the surface of cleaning element 2, the coverage area of ​​the first cleaning element 21 is larger than that of the second cleaning element 22. The first cleaning element 21 can be made of traditional fiber cloth, which has a good cleaning effect and relatively low production cost. For the cleaning element 2 of this disclosure, the first cleaning element 21 plays the most important cleaning role. The second cleaning element 22, which has strong elasticity, is mainly used for intermittent contact with the liquid outlet 31. Therefore, the second cleaning element 22 can be set only at the location where it can pass through the liquid outlet 31, without having to cover a large area of ​​the surface of the cleaning element 2. This ensures that the cleaning ability of the cleaning element 2 is not reduced by setting the second cleaning element 22, and effectively controls the production cost of the cleaning element 2.

[0070] In one embodiment of this disclosure, such as Figure 2 As shown, the cleaning element 2 is configured to extend along the first axis, and the second cleaning element 22 is configured to be spirally spaced or continuously distributed on the surface of the cleaning element 2 along the first axis. Further, as... Figure 7 As shown, multiple liquid outlets 31 are provided, distributed along the first axis on the liquid outlet assembly 3, and configured to be located on the movement path of the second cleaning component 22. Figure 2 The X-axis marked in the figure is the first axis. The second cleaning element 22 is spirally distributed at intervals or continuously along the X-axis direction on the surface of the cleaning element 2. Thus, as the cleaning element body 20 rotates, the second cleaning element 22 can intermittently contact each liquid outlet 31.

[0071] This disclosure arranges the second cleaning element 22 in a spiral manner on the surface of the cleaning element 2, thereby preventing the second cleaning element 22 from simultaneously scraping all the liquid outlets 31, and thus preventing the liquid outlets 31 from having difficulty supplying cleaning liquid to the first cleaning element 21. It is understood that for the multiple liquid outlets 31 distributed along the first axis on the liquid outlet assembly 3, the timing and flow rate of liquid supply to each liquid outlet 31 are basically the same. If the second cleaning element 22 is arranged linearly along the first axis on the surface of the cleaning element 2, it will allow the second cleaning element 22 to contact all the liquid outlets 31 simultaneously. If cleaning liquid happens to drip from each liquid outlet 31 at this time, all the dripping cleaning liquid will fail to reach the first cleaning element 21, thus making it difficult to wet the first cleaning element 21. Figure 2 As shown, the present disclosure arranges the second cleaning component 22 in a spiral. Taking the case where the second cleaning component 22 is spirally arranged around three times as an example, the second cleaning component 22 can contact three liquid outlets 31 at the same time, while the other liquid outlets 31 can drip cleaning liquid onto the first cleaning component 21 at this time. This ensures that the first cleaning component 21 can be evenly wetted, thus ensuring the cleaning efficiency and effect.

[0072] This disclosure preferably involves continuously distributing the second cleaning element 22 on the surface of the cleaning element 2. Specifically, taking the squeegee 4 pressing the second cleaning element 22 as an example, for the continuously distributed second cleaning element 22, the squeegee 4 always maintains pre-pressure on a portion of the second cleaning element 22. During rotation, the spirally extended second cleaning element 22 continuously changes its compressed position, thus preventing jamming. It is evident that the continuously distributed second cleaning element 22 has a certain pressure guiding effect, ensuring smooth rotation of the cleaning element 2 and preventing jamming.

[0073] In one embodiment of this disclosure, the second cleaning element 22 is configured to contact each outlet 31 once during one rotation. During one rotation, all outlets 31 will contact the second cleaning element 22 once, thereby ensuring that none of the outlets 31 will leak. If any outlet 31 fails to contact the second cleaning element 22, the water film formed at that outlet 31 cannot be broken by the second cleaning element 22, and the water film will flow along the wall, causing dripping or leakage in the cleaning equipment. Furthermore, after prolonged use, such outlets 31 are prone to clogging with lint, dust, and other dirt. This embodiment is designed to ensure that the second cleaning element 22 can evenly wipe each outlet 31 during one rotation, ensuring that none of the outlets 31 leak.

[0074] In one embodiment of this disclosure, reference is made to Figure 5The outlet 31 is configured to be located above the cleaning element 2, and the cleaning liquid from the outlet 31 is configured to drip downwards onto the surface of the cleaning element 2 under its own gravity. Specifically, the outlet 31 can be located directly above the cleaning element 2, so that the cleaning liquid can drip naturally onto the surface of the cleaning element 2 by gravity alone, without the need for an additional liquid discharge power mechanism. Furthermore, when the second cleaning member 22 rotates to the adjacent directly above position, it is no longer subjected to pressure from the working surface and has restored its radial dimensions; see reference. Figure 4 In this disclosure, the outlet 31 is positioned above the cleaning element 2, so that the second cleaning element 22, which has restored its radial dimensions, can fully contact the outlet 31, ensuring the effect of piercing the water film and preventing leakage.

[0075] In one embodiment of this disclosure, reference is made to Figure 4 The liquid outlet assembly 3 is provided with a liquid outlet channel 32, which is used to supply cleaning liquid to the liquid outlet 31. (Reference) Figure 6 and Figure 9 The liquid outlet channel 32 includes a first channel 321, a dripping channel 323, and a second channel 322 connected in sequence. The inner diameter of the dripping channel 323 is smaller than that of the second channel 322. The liquid flowing in the first channel 321 is configured to collect in the dripping channel 323 and then flow out from the outlet 31 of the second channel 322. Specifically, the inner diameter of the dripping channel 323 is much smaller than that of the second channel 322. In the direction of liquid flow, the inner diameter of the outlet channel 32 suddenly increases (i.e., from the dripping channel 323 into the second channel 322), thereby enabling the cleaning liquid to form droplets when flowing out of the dripping channel 323, avoiding excessive flow and the formation of a liquid flow. The cleaning liquid falling in droplets will not adhere to the wall, but can fall directly onto the first cleaning component 21 or the second cleaning component 22, thereby reducing the probability of forming a water film at the outlet 31 and further avoiding dripping and leakage problems in the cleaning equipment.

[0076] In one embodiment of this disclosure, such as Figure 6 As shown, the inner diameter of the second channel 322 is designed to gradually increase from top to bottom. The droplets formed in the dripping channel 323 will drip from top to bottom into the second channel 322. When the droplets enter the second channel 322, they are unlikely to adhere to the wall, and during their descent, they may deviate at a certain angle, making it impossible to ensure that their dripping path is completely vertical. Therefore, the gradually increasing inner diameter of the second channel 322 provides a certain amount of offset space during the droplet's descent, thereby further reducing the probability of the droplets adhering to the wall.

[0077] In one embodiment of this disclosure, the inner diameter of the dripping channel 323 is smaller than the inner diameter of the first channel 321. In the liquid flow direction, the inner diameter of the outlet channel 32 suddenly decreases (i.e., the liquid enters the dripping channel 323 from the first channel 321), thereby causing liquid to accumulate at the bottom of the first channel 321. (See reference...) Figure 6 and Figure 9 A liquid collecting tank 3211 is provided in the first channel 321 near the dripping channel 323. The liquid in the first channel 321 is configured to at least partially accumulate in the liquid collecting tank 3211 and flow out through the dripping channel 323. The liquid collecting tank 3211 can be a recessed structure provided in the first channel 321, which is located at the liquid inlet end of the corresponding dripping channel 323. This allows a certain amount of liquid to accumulate above the dripping channel 323, enabling the dripping channel 323 to smoothly drip full and abundant droplets.

[0078] In one embodiment of this disclosure, reference is made to Figure 6 and Figure 8 The liquid dispensing assembly 3 is equipped with a blocking groove 33, which is configured to surround the outer side of the liquid outlet 31. When the liquid from the outlet 31 has already flowed along the wall and formed a water film, the blocking groove 33 prevents the liquid from flowing further down the wall. When the water film spreads along the wall to the blocking groove 33, it is difficult for the water film to rise into the blocking groove 33 under the influence of gravity. Therefore, it accumulates at the blocking groove 33 and gradually forms droplets, which then drip onto the surface of the cleaning element 2. This effectively prevents the liquid from continuously climbing the wall, avoiding the formation of droplets or watermarks at the rear end of the cleaning element 2, thus improving the user experience.

[0079] In one embodiment of this disclosure, reference is made to Figure 4 and Figure 5 The body 1 is provided with a cavity for installing the cleaning element 2. In the radial direction, the first cleaning element 21 and the second cleaning element 22 are configured to have a predetermined gap 5 between them and the inner wall of the cavity. This ensures that the inner wall of the cavity will not come into frictional contact with the surface of the cleaning element 2 during rotation, thus avoiding wear of the cleaning element.

[0080] refer to Figure 8 The liquid outlet assembly 3 includes a protrusion 30 protruding from the inner wall of the cavity. The blocking groove 33 and the liquid outlet 31 are configured to be disposed on the protrusion 30. The protrusion 30 can extend into the predetermined gap 5. During the water-assisted cleaning process, there is still a certain amount of gap between the protrusion 30 and the first cleaning component 21, and the first cleaning component 21 will not come into contact with the protrusion 30. The second cleaning component 22 will be press-fitted with the protrusion 30, thereby wiping and puncturing the water film at the liquid outlet 31 and the blocking groove 33, thus avoiding dripping and leakage problems in the cleaning equipment.

[0081] Furthermore, the protrusion 30 can further prevent liquid from continuously climbing the wall. Specifically, even if the water film crosses the blocking groove 33, when the water film spreads along the wall to the edge of the protrusion 30, it is difficult for the water film to climb up the side wall of the protrusion 30 under the action of gravity. Therefore, it will accumulate at the edge of the protrusion 30 and gradually form droplets, which will drip onto the surface of the cleaning element 2. This effectively prevents the liquid from continuously climbing the wall, avoiding the formation of droplets or watermarks at the rear end of the cleaning element and improving the user experience.

[0082] According to a second aspect of this disclosure, a cleaning device is also provided, comprising a cleaning element 2 and a liquid outlet assembly 3. The cleaning element 2 includes a cleaning element body 20, on the surface of which a first cleaning element 21 and a second cleaning element 22 are disposed. The elastic force of the second cleaning element 22 is greater than that of the first cleaning element 21. At least during water-based cleaning, the second cleaning element 22 is configured to naturally extend beyond the first cleaning element 21 in the radial direction, and the second cleaning element 22 is configured to intermittently contact the liquid outlet 31 of the liquid outlet assembly 3 during rotation with the cleaning element body 20. This allows the water film formed at the liquid outlet 31 to be punctured upon contact, preventing the water film from flowing further along the wall surface and solving the problems of dripping and leakage in the cleaning device. Furthermore, the second cleaning element 22 can also wipe and clean the liquid outlet 31 when in contact, reducing or even preventing the liquid outlet 31 from being blocked by lint, dust, or other dirt.

[0083] According to a third aspect of this disclosure, a cleaning device is also provided, comprising: a cleaning element 2, a mounting cavity, and a liquid dispensing assembly 3. The cleaning element 2 is configured to clean a work surface. The mounting cavity is used to accommodate the cleaning element 2; specifically, the mounting cavity can be a cavity provided on the body 1 as described above, and the cleaning element 2 can be installed in the mounting cavity. The liquid dispensing assembly 3 includes a liquid outlet 31, configured to provide cleaning liquid to the cleaning element 2; wherein the liquid dispensing assembly 3 is provided with a blocking groove 33, configured to surround the outer side of the liquid outlet 31.

[0084] When the liquid from the outlet 31 has already flowed along the wall and formed a water film, the blocking groove 33 prevents the liquid from flowing further down the wall. When the water film spreads along the wall to the blocking groove 33, it is difficult for the water film to rise into the blocking groove 33 under the influence of gravity. Therefore, it accumulates at the blocking groove 33 and gradually forms droplets, which then drip onto the surface of the cleaning element 2. This prevents the liquid from continuously climbing the wall, avoiding the formation of droplets or watermarks at the rear end of the cleaning element 2, thus improving the user experience.

[0085] In one embodiment of this disclosure, the liquid outlet assembly 3 includes a protrusion 30 protruding from the inner wall of the mounting cavity, and an obstruction groove 33 and a liquid outlet 31 are configured to be disposed on the protrusion 30. During the water-based cleaning process, the protrusion 30 can be press-fitted with a portion of the cleaning element 2, so that the liquid outlet 31 and the obstruction groove 33 can be wiped and the water film can be punctured through this portion of the cleaning element 2, thus avoiding dripping or leakage problems in the cleaning equipment.

[0086] According to a fourth aspect of this disclosure, a cleaning device is also provided, comprising: a mounting cavity, a cleaning element 2, and a liquid dispensing assembly 3. The mounting cavity is used to accommodate the cleaning element 2; specifically, the mounting cavity may be a cavity disposed on the body 1 as described above. The cleaning element 2 is used to clean a working surface, and a second cleaning component 22 is disposed on the surface of the cleaning element 2. The liquid dispensing assembly 3 includes a liquid outlet 31, which is configured to provide cleaning liquid to the cleaning element 2. The liquid outlet 31 is located on the movement path of the second cleaning component 22; during the water-based cleaning process, the second cleaning component 22 is configured to intermittently contact the liquid outlet 31 during rotation.

[0087] This disclosure solves the problems of dripping and leakage in the cleaning equipment by incorporating a second cleaning component 22. The second cleaning component 22 intermittently contacts the liquid outlet 31 during rotation, thereby puncturing the water film formed at the outlet 31 upon contact and preventing the water film from flowing further down the wall. Furthermore, the second cleaning component 22 can also wipe and clean the outlet 31 when in contact, reducing or even preventing the outlet 31 from being clogged by lint, dust, or other dirt.

[0088] Application scenarios

[0089] The cleaning equipment is a sweeping and mopping robot, comprising a body 1, a cleaning element 2, and a liquid dispensing assembly 3. The liquid dispensing assembly 3 includes multiple liquid outlets 31 arranged along a first axis, configured to provide cleaning liquid to the cleaning element 2. The cleaning element 2 is a roller, comprising a cleaning element body 20 rotatably connected to the body 1. The surface of the cleaning element body 20 is provided with a first cleaning element 21 and a second cleaning element 22. During the water-assisted cleaning process, at least a portion of the second cleaning element 22 extends radially beyond the first cleaning element 21. The second cleaning element 22 is configured to intermittently contact the liquid outlets 31 as it rotates with the cleaning element body 20.

[0090] The first cleaning element 21 and the second cleaning element 22 are flocked fibers implanted on the surface of the cleaning element body 20. Specifically, the first cleaning element 21 can be formed by mixing polyester fiber 300D576F and polyester fiber 300D96F; the second cleaning element 22 can be formed by nylon fiber 900D57F, and the second cleaning element 22 is constructed as a mesh-like woven structure. Due to the difference in materials and weaving structure, the elastic force of the second cleaning element 22 is greater than that of the first cleaning element 21; at least during the water-based cleaning process, the second cleaning element 22 is constructed to naturally recover to extend radially beyond the first cleaning element 21.

[0091] When subjected to compressive force, such as when rotating to contact the working surface, both the second cleaning component 22 and the first cleaning component 21 are compressed into contact with the working surface under the weight of the cleaning equipment itself, thus achieving a better cleaning effect. When rotating to a state where the compressive force is no longer applied, the second cleaning component 22, due to its better elasticity, can rebound and restore its radial dimension; while the first cleaning component 21, due to its relatively poor elasticity and the collapse of fibers caused by water, rebounds much less than the second cleaning component 22.

[0092] This design ensures that during the water-based cleaning process, at least a portion of the second cleaning component 22 extends radially beyond the first cleaning component 21. The second cleaning component 22 can intermittently contact the outlet 31, thereby puncturing the water film formed at the outlet 31 upon contact, preventing the water film from flowing further down the wall and solving the problems of dripping and leakage in the cleaning equipment. Furthermore, the second cleaning component 22 can also wipe and clean the outlet 31 upon contact, thus preventing the outlet 31 from being clogged by lint, dust, or other dirt.
