[0052] This disclosure provides a window cleaning robot and a cleaning component. The window cleaning robot includes the cleaning component. The specific structure and working principle of the window cleaning robot provided in this disclosure will be described in detail below with reference to the accompanying drawings and three specific embodiments. The specific structure and working principle of the cleaning component provided in this disclosure will also be introduced at the same time.
[0053] Example 1 refer to Figure 1 and Figure 2 This disclosure provides a window cleaning robot, including: a body 1, a cleaning component 2, and an adsorption assembly. The body 1 serves as the core supporting structure, supporting all components of the window cleaning robot. The cleaning component 2 is mounted on the body 1, and the adsorption assembly is mounted on the body 1 and configured to provide adsorption force to the window cleaning robot. The cleaning component 2 is used to clean the surface to be cleaned; it can be a cloth mounted on the side of the body 1 facing the surface to be cleaned, and the cleaning component 2 has a cleaning surface. During the operation of the window cleaning robot, the cleaning surface can adhere to and adsorb onto surfaces such as windows, glass, walls, tiles, and mirrors, allowing the window cleaning robot to perform cleaning operations on vertical surfaces to be cleaned.
[0054] The cleaning component 2 includes an inner annular contour (the side closest to the center of the body 1), an outer annular contour (the side closest to the edge of the body 1), and a cleaning area formed between the inner and outer annular contours. The shape of the inner annular contour is adapted to the central area of the body 1 (such as the periphery of the negative pressure port 30 of the adsorption component), and the shape of the outer annular contour is adapted to the outer periphery of the body 1. The cleaning area, located between the inner and outer annular contours, is the core area where the cleaning component 2 achieves stain removal. Figure 3 As shown, both the inner and outer annular contours of the cleaning component 2 can be provided with thick edging. The edging can be made of wear-resistant fabric material, which is used to ensure the overall structural stability of the cleaning component 2.
[0055] refer to Figure 1 and Figure 2 The cleaning area includes at least a first area 201 and a second area 202. The first area 201 is located on the outer periphery of the annular inner contour and forms a sealing ring when the cleaning component 2 is adsorbed onto the surface to be cleaned. The adsorption assembly is configured to provide adsorption force to the first area 201. Specifically, the window cleaning robot relies on the negative pressure generated by the adsorption assembly to adhere to the surface to be cleaned. The adsorption assembly can be a built-in centrifugal fan or an axial fan, which is fixed by a pre-set mounting cavity inside the body 1. (Reference) Figure 1The adsorption component can have a negative pressure port 30 for drawing air. The negative pressure port 30 can be located on the side of the body 1 facing the surface to be cleaned, and a sealing ring formed in the first region 201 can be arranged around the negative pressure port 30. During the cleaning process of the window cleaning robot, after the adsorption component is activated, it can continuously draw air through the negative pressure port 30, so that the sealing ring forms a negative pressure environment lower than the outside atmospheric pressure. This utilizes the air pressure difference to firmly adsorb the window cleaning robot onto the surface to be cleaned, preventing it from falling off due to gravity when working at height.
[0056] After achieving stable adsorption, the window cleaning robot can complete autonomous movement operations via the walking system mounted on its body 1. In one embodiment of this disclosure, reference is made to... Figure 1 The robot body 1 is equipped with a walking component 11, which may include components such as wheels or tracks to enable walking. The robot is driven along a preset path by the friction between the walking component 11 and the surface to be cleaned. To achieve comprehensive cleaning, the robot is equipped with a path planning function. Using sensing components (e.g., infrared sensors, ultrasonic sensors, or vision sensors) on the body 1, it can detect the boundaries of the surface to be cleaned and the positions of obstacles in real time. The system can intelligently plan zigzag, bow-shaped, spiral, or edge-cleaning paths to ensure that the robot can cover the entire surface and avoid creating blind spots.
[0057] Furthermore, a water supply system can be installed on the body 1, which may include a clean water tank and a spray component connected to the clean water tank. The spray component is used to spray the cleaning liquid (such as clean water, cleaning solution, disinfectant, etc.) stored in the clean water tank onto the path of the window cleaning robot. The cleaning liquid can soften the stains on the surface to be cleaned, reduce the difficulty of subsequent cleaning, and help improve the cleaning effect of the cleaning component 2. In addition, during the cleaning process, the cleaning component 2 will be gradually moistened by the cleaning liquid. The moistened cleaning component 2 can enhance the airtightness between the cleaning area and the surface to be cleaned, ensuring that the sealing ring remains sealed, thereby improving the suction power of the window cleaning robot. For example, the cleaning component 2 made of fluffy fiber material will expand slightly after absorbing water, thereby filling the tiny gaps between the cleaning surface and the surface to be cleaned, thus improving the airtightness of the sealing ring and strengthening the negative pressure suction effect.
[0058] The shape of the cleaning area can be adapted to the shape of the body 1 of the window cleaning robot. For example, in this embodiment, the body 1 is a rounded rectangular structure, so the cleaning surface can also be set to an approximately rectangular shape, and correspondingly, the sealing ring is approximately rectangular. In embodiments where the body 1 is circular, the cleaning surface can also be set to a circular shape, and its sealing ring can also be set to a circular shape. This disclosure does not limit the specific shape of the cleaning area.
[0059] refer to Figure 2 and Figure 4 The first region 201 contains a first cleaning unit 21. When adsorbed onto the surface to be cleaned, the first cleaning unit 21 is configured to form a sealing ring, thereby creating a sealed fit between the first cleaning unit 21 and the surface to be cleaned. The first cleaning unit 21 can be a commonly used wiping cloth, which plays a major role in cleaning by wiping away dirt from the surface to be cleaned. Furthermore, the close fit of the wiping cloth when adsorbed onto the surface to be cleaned forms a stable sealing structure, thus preventing the window cleaning robot from falling. The second region 202 partially overlaps with the first region 201; the second region 202 contains a second cleaning unit 22, which is configured to scrape the surface to be cleaned. Specifically, the second cleaning unit 22 can be made of a relatively stiff fibrous material, enabling it to scrape away stubborn stains from the surface to be cleaned.
[0060] This disclosure effectively balances the cleaning effect and sealing performance of the cleaning component 2 by dividing the cleaning area into a first area 201 and a second area 202. Specifically, the first area 201 is equipped with a first cleaning unit 21, such as a velvet cloth. The first cleaning unit 21 not only cleans but also forms a sealing ring, thus stably adhering to the window surface, reducing the risk of the window cleaning robot falling off during high-altitude operations and ensuring safety. The second area 202 is equipped with a second cleaning unit 22, which can be made of a rigid fiber material, thereby providing a scraping effect and enhancing the cleaning effect on stubborn stains.
[0061] The first region 201 of this disclosure is disposed on the outer periphery of the annular inner contour, and a first cleaning unit 21 for cleaning the surface to be cleaned is disposed in the first region 201; the second region 202 is also disposed on the outer periphery of the annular inner contour, and a second cleaning unit 22 for scraping the surface to be cleaned is disposed in the second region 202. When the cleaning component 2 is adsorbed onto the surface to be cleaned, the first region 201 and the second region 202 together form a sealing ring. Specifically, when the cleaning component 2 is adsorbed onto the surface to be cleaned, the flexible first cleaning unit 21 in the first region 201 adheres to the surface to be cleaned due to negative pressure, thereby forming a basic sealing layer; although the second cleaning unit 22 in the second region 202 is made of a relatively rigid material, under the action of negative pressure, its edge is in close contact with the surface to be cleaned, thereby making the first region 201 and the second region 202 together constitute a sealing ring covering the entire cleaning area.
[0062] The first cleaning unit 21 (flexible fluff fiber) in the first region 201 can fully fill the tiny gap between the cleaning component 2 and the surface to be cleaned, achieving a core sealing effect; the second cleaning unit 22 (hard scraping fiber) in the second region 202 can also tightly adhere to the surface to be cleaned under negative pressure, thereby further blocking the leakage path. Compared with the solution of setting only a single region for sealing, this disclosure reduces the negative pressure leakage rate by setting a sealing ring formed by the first region 201 and the second region 202, thereby ensuring stable adsorption of the window cleaning robot when it is working at height, without the risk of falling off.
[0063] Due to the material properties of the second cleaning unit 22, while the second area 202 has a strong cleaning effect, it also has relatively poor sealing performance. Therefore, setting the second cleaning unit 22 on the cleaning component 2 may compromise the airtightness, leading to a decrease in the negative pressure adsorption stability of the window cleaning robot, and thus creating a risk of detachment during high-altitude operations, threatening the safety of users' property and living environment. To solve the above problems, in one embodiment of this disclosure, reference is made to... Figure 2 and Figure 4 The second cleaning unit 22 is configured to enclose a preset gap 23, and a portion of the first cleaning unit 21 is configured to protrude through the preset gap 23 to seal against the surface to be cleaned. Specifically, the preset gap 23 enclosed by the second cleaning unit 22 allows a portion of the first cleaning unit 21 to protrude, thereby increasing the contact area between the first cleaning unit 21 and the surface to be cleaned. This forms a sealing structure around the second cleaning unit 22, preventing the addition of the second cleaning unit 22 from disrupting the adsorption seal.
[0064] In one embodiment of this disclosure, reference is made to Figure 4 The second cleaning unit 22 is constructed as a mesh structure, with pre-defined gaps 23 forming the mesh openings. The mesh structure can be made using a weaving process, and its mesh openings should be of sufficient size to allow the first cleaning unit 21 to pass through. The mesh openings can be circular, square, rhomboid, polygonal, or other shapes; this disclosure does not specifically limit the shape of the mesh openings in the mesh structure. The mesh openings of the mesh structure are evenly distributed, ensuring that the contact points between the first cleaning unit 21 passing through the mesh and the surface to be cleaned are uniform and dense, thereby resulting in a more balanced distribution of sealing pressure and reducing negative pressure leakage. Specifically, the first cleaning unit 21 is partially exposed through the mesh openings. When the window cleaning robot adheres to the surface to be cleaned, the first cleaning unit 21 can fill the mesh openings, thereby filling the internal space of the mesh openings and at least part of the gaps between adjacent mesh openings, thus achieving a sealing effect. In addition, the mesh structure naturally has a certain degree of elasticity. During the cleaning process, the mesh structure can undergo slight deformation along with the cleaning surface, thereby adapting to any microscopic unevenness that may exist on the surface to be cleaned. This ensures that the cleaning area and the surface to be cleaned can remain in close contact, reducing local air leakage and ensuring the stability of adsorption.
[0065] In one specific embodiment of this disclosure, the second cleaning unit 22 can be bonded to the first cleaning unit 21. Specifically, the second cleaning unit 22 can be bonded to the side of the first cleaning unit 21 facing the surface to be cleaned, thereby making the first cleaning unit 21 and the second cleaning unit 22 together constitute a complete cleaning area. It should be noted that when using the bonding process, a water-resistant and aging-resistant adhesive should be selected, and the adhesive application area can be concentrated at the edge of the second cleaning unit 22 to ensure that there are no obvious gaps after bonding.
[0066] In another specific embodiment of this disclosure, the second cleaning unit 22 is sewn onto the first cleaning unit 21. Specifically, the second cleaning unit 22 can be sewn onto the side of the first cleaning unit 21 facing the surface to be cleaned, thereby making the first cleaning unit 21 and the second cleaning unit 22 together constitute a complete cleaning area. It should be noted that when using the sewing process, it is necessary to select thread with appropriate strength and use an overlock sewing process to ensure the stability and firmness of the sewn structure.
[0067] This disclosure employs adhesive or sewing methods to connect the second cleaning unit 22 to the first cleaning unit 21, thereby improving the stability of the connection and ensuring that the second cleaning unit 22 will not detach from the surface of the first cleaning unit 21 during the operation of the window cleaning robot and during the user's washing of the cleaning component 2. Specifically, the water-resistant adhesive maintains stable adhesion after contact with cleaning liquid, and the sewing process achieves reliable fixation through mechanical interlocking, significantly reducing the probability of the second cleaning unit 22 detaching. In addition, both connection methods are mature and inexpensive, suitable for mass production needs.
[0068] In one embodiment of this disclosure, the first cleaning unit 21 is made of a first fiber material, and the second cleaning unit 22 is made of a second fiber material, wherein the hardness of the second fiber material is greater than that of the first fiber material. Specifically, the first fiber material should possess certain elasticity, hygroscopicity, and dirt-holding capacity, thereby adapting to the surface to be cleaned and meeting the adhesion requirements. The low hardness and high elasticity of the first fiber material ensure that the first cleaning unit 21 fits tightly against the surface to be cleaned, guaranteeing sealing performance. The hygroscopicity of the first fiber material allows it to expand slightly under the action of the cleaning liquid, thereby further reducing the gap between the cleaning area and the surface to be cleaned and enhancing negative pressure stability.
[0069] The second fiber material should possess high strength and abrasion resistance to withstand the wear and tear caused by scraping operations. The high hardness and abrasion resistance of the second fiber material effectively remove stubborn stains from the surface to be cleaned, improving cleaning efficiency and effectiveness. This disclosure overcomes the limitations of existing technologies where a single fiber material is "weak in cleaning power when soft and poor in sealing when hard," by setting up a first cleaning unit 21 and a second cleaning unit 22 made of different materials. It innovatively provides a cleaning component 2 that can balance both cleaning and sealing performance.
[0070] In one specific embodiment of this disclosure, the first fiber material can be a fluffy fiber. The fluffy fiber has a fine diameter, is soft, and is fluffy in a dry state, exhibiting good dirt-holding capacity. The fine diameter and fluffy nature of the fluffy fiber increase the contact area between the first cleaning unit 21 and the surface to be cleaned, improving the filling effect of tiny gaps and resulting in better sealing performance than traditional cloths. Simultaneously, the soft texture of the fluffy fiber prevents the first cleaning unit 21 from scratching the surface during the window cleaning robot's movement, enhancing the user experience. Furthermore, the surface of the fluffy fiber can be hydrophilically treated, thereby improving its water absorption capacity. This hydrophilic treatment accelerates the water absorption speed of the first cleaning unit 21, and the fibers slightly swell after absorbing water, further enhancing the sealing performance of the first cleaning unit 21.
[0071] In one specific embodiment of this disclosure, the second fiber material is one of PP fiber, polyester fiber, or polyester film fiber. All three types of fibers possess higher strength than the first fiber material, maintain good performance even in a wet state, exhibit excellent abrasion resistance, and high rigidity, making them suitable for scraping stubborn stains. Furthermore, all three fibers are manufactured using mature spinning processes, resulting in a smooth, burr-free surface. This allows the second cleaning unit 22 to scrape stubborn stains from the surface while avoiding scratching it, balancing cleaning power with user experience.
[0072] In one embodiment of this disclosure, the first region 201 is configured to be continuously disposed on the outer periphery of the annular inner contour and is configured to have an annular structure. Specifically, the first region 201 is distributed in a continuous, uninterrupted annular structure on the outer periphery of the annular inner contour of the cleaning component 2, and its annular range is completely within the sealing ring enclosed by the inner and outer contours of the cleaning component 2. The first region 201 is the core sealing region of the sealing ring. The annular structure of the first region 201 is adapted to the overall shape of the cleaning area, and the first cleaning unit 21 forms a continuous contact sealing layer covering the entire first region 201. The continuous annular structure ensures that the contact between the first cleaning unit 21 and the surface to be cleaned is uninterrupted, and the negative pressure can be evenly applied to the entire first region 201, forming a stable and uniform sealing effect.
[0073] It should be noted that even if the sealing performance of the second area 202 is affected by the installation of the second cleaning unit 22, the continuous annular seal of the first area 201 can still independently maintain the negative pressure level within the sealing ring, ensuring that the window cleaning robot obtains sufficient adsorption force and effectively avoiding the risk of adsorption failure. The continuous annular seal of the first area 201 ensures adsorption safety and improves the sealing fault tolerance rate of the window cleaning robot in complex cleaning scenarios.
[0074] In one embodiment of this disclosure, the second region 202 is located adjacent to the outer contour of the cleaning component 2. The second region 202's proximity to the outer contour of the cleaning component 2 enhances the cleaning effect at the edges of the cleaning area, thereby improving the cleaning effect of the window cleaning robot during edge cleaning (such as cleaning along window frames). Furthermore, as the window cleaning robot moves, the second region 202 can preferentially contact the area to be cleaned on the surface. This allows the scraping action of the second cleaning unit 22 in the second region 202 to preferentially handle stubborn stains while softening them. This means that the subsequent first cleaning unit 21 in the first region 201 only needs to clean the softened, loose stains, reducing cleaning difficulty, improving overall cleaning efficiency, and solving the problem that stubborn stains are difficult for the first cleaning unit 21 in the first region 201 to clean.
[0075] Furthermore, the first region 201 is located inside the sealing ring near the negative pressure port 30 of the adsorption component, forming a ring-shaped structure surrounding the negative pressure port 30. The ring-shaped structure of the first region 201 is complete and independent. The second region 202 is located near the outer contour, thus not compromising the ring-shaped integrity and coverage of the first region 201, and not interfering with the adhesion between the first cleaning unit 21 and the surface to be cleaned. In the sealing ring of this disclosure, the second region 202 and the first region 201 form an independent layout. The outermost second region 202 ensures that the first region 201 maintains its ring-shaped configuration surrounding the negative pressure port 30, ensuring the adsorption performance of the window cleaning robot.
[0076] In one specific embodiment of this disclosure, the direction of travel of the window cleaning robot on the surface to be cleaned is denoted as forward. For example... Figure 2 As shown, the second region 202 is located at the front end of the cleaning region and is configured to be located in front of the first region 201, and / or, the second region 202 is located at the rear end of the cleaning region and is configured to be located behind the first region 201. Specifically, in this embodiment, two second regions 202 are provided, and the two second regions 202 are located at the front and rear sides of the cleaning component 2, respectively. The two second regions 202 are symmetrically arranged on the front and rear sides of the cleaning component 2 about the center line of the cleaning region.
[0077] This disclosure sets the placement of the second area 202 in conjunction with the travel direction of the window cleaning robot. The second area 202 located at the front can scrape the stubborn stains in the area to be cleaned in advance, softening the stains. This allows the first cleaning unit 21 of the first area 201 to only clean the softened, loose stains, reducing the cleaning difficulty and improving the cleaning efficiency. The second area 202 located at the rear can perform a second scraping on the cleaned area to remove residual water stains and impurities, optimizing the cleaning effect.
[0078] Furthermore, the design of having second zones 202 on both the front and rear sides enables bidirectional cleaning. When the window cleaning robot moves forward, the second zone 202 on the front side performs a scraping cleaning function; when the window cleaning robot moves backward, the second zone 202 on the rear side performs the same scraping cleaning function. This allows for reciprocating cleaning without adjusting the robot's direction of travel, improving cleaning efficiency. In addition, the two second zones 202 provide functional backup; even if the second cleaning unit 22 in one second zone 202 wears out, the other second zone 202 can still maintain a certain scraping effect, extending the service life of the cleaning component 2.
[0079] In one embodiment of this disclosure, the second region 202 is configured to cover the travel path of the first region 201 in the forward or backward direction. Specifically, in the left-right direction perpendicular to the forward-backward direction, the width of the second region 202 is greater than or equal to the width of the first region 201, that is, all cleaning areas of the first region 201 in the left-right direction are within the left-right coverage of the second region 202. This width matching relationship is maintained regardless of whether the window cleaning robot is in a forward or backward state, thereby ensuring that every cleaning area on the travel path of the first region 201 is spatially covered by the second region 202. This ensures the comprehensive coverage of the scraping function and eliminates blind spots in which the second cleaning unit 22 in the second region 202 cannot perform scraping cleaning.
[0080] Specifically, wherever the first area 201 reaches, the corresponding area has already been pre-treated by the second cleaning unit 22 in the second area 202 (such as scraping away stubborn stains and softening stains), ensuring that the scraping function covers the entire cleaning path of the first area 201. This coverage design ensures that there are virtually no unscraped areas on the surface to be cleaned, avoiding the problem of insufficient cleaning power of the first cleaning unit 21. Every area on the surface to be cleaned undergoes a cleaning process of first hard scraping and then soft wiping, thereby improving the uniformity and thoroughness of cleaning and effectively avoiding the problem of local stain residue caused by missed scraping.
[0081] In one embodiment of this disclosure, the cleaning component 2 has notches 203 on its left and right sides for the walking component 11 to extend out. The shape of the notches 203 can be adapted to the structure of the walking component 11, and the position of the notches 203 avoids the sealing ring, thereby exposing the walking component 11 without affecting the sealing performance of the cleaning component 2. The walking component 11 extends through the notches 203 without direct contact with the cleaning component 2, reducing negative pressure leakage and improving the sealing effect.
[0082] Example 2 This embodiment also provides a window cleaning robot and cleaning component 2. The main difference from Embodiment 1 is that the specific structure of cleaning component 2 is different. Apart from cleaning component 2, the other structures and working principles of the window cleaning robot are completely consistent with Embodiment 1, and will not be described again in this embodiment.
[0083] The cleaning component 2 in this embodiment includes an inner annular contour, an outer annular contour, and a cleaning area formed between the inner and outer annular contours. The cleaning area includes a first area 201 and a second area 202. The first area 201 is disposed on the outer periphery of the inner annular contour and forms a sealing ring when the cleaning component 2 is adsorbed onto the surface to be cleaned. The second area 202 is disposed outside the first area 201, and a second cleaning unit 22 is disposed in the second area 202. The second cleaning unit 22 is configured to scrape the surface to be cleaned.
[0084] As described in Embodiment 1, the first cleaning unit 21 can be a commonly used cleaning cloth in the prior art, made of a first fiber material such as fluffy fibers. The first cleaning unit 21, while providing a cleaning effect, can also form a sealing ring, thereby stably adhering to the window surface, reducing the risk of the window cleaning robot falling off during high-altitude operations and ensuring safety. The second cleaning unit 22 can be made of a rigid second fiber material (such as PP fiber, polyester fiber, or polyester film fiber), which can exert a scraping action and enhance the cleaning effect on stubborn stains.
[0085] The first region 201 is constructed as a continuous ring around the outer periphery of the inner ring contour, forming a ring structure, thereby creating a stable sealing effect. The second region 202 is located outside the first region 201. Therefore, the second cleaning unit 22 located in the second region 202 can contact the dirt before the first cleaning unit 21 in the first region 201. The second cleaning unit 22 can scrape away stubborn stains in the area to be cleaned in advance, softening the stains. This allows the first cleaning unit 21 in the first region 201 to only clean the softened, loose stains, reducing the cleaning difficulty and improving cleaning efficiency.
[0086] In one embodiment of this disclosure, the second region 202 may be located at the front end of the cleaning area and in front of the first region 201, and / or the second region 202 may be located at the rear end of the cleaning area and in front of the first region 201. In this embodiment, two second regions 202 are provided, located at the front and rear sides of the cleaning component 2, respectively. The second region 202 located at the front can scrape stubborn stains in the area to be cleaned in advance, softening the stains, so that the first cleaning unit 21 of the first region 201 only needs to clean the softened loose stains, improving cleaning efficiency; the second region 202 located at the rear can perform a second scraping on the cleaned area to remove residual water stains and impurities, optimizing the cleaning effect.
[0087] Furthermore, the design of having second areas 202 on both the front and rear sides enables bidirectional cleaning. When the window cleaning robot moves forward, the second area 202 on the front side can perform a scraping cleaning function, and when the window cleaning robot moves backward, the second area 202 on the rear side can perform a scraping cleaning function. In this way, reciprocating cleaning can be completed without adjusting the travel direction of the robot body 1, improving cleaning efficiency. In one embodiment of this disclosure, the second region 202 is configured to cover the travel path of the first region 201 in either the forward or backward direction. Thus, regardless of whether the window cleaning robot is moving forward or backward, every cleaning area along the travel path of the first region 201 can be spatially covered by the second region 202. This ensures comprehensive coverage of the scraping function, eliminates blind spots in the second cleaning unit 22 within the second region 202 that cannot perform scraping cleaning, improves the uniformity and thoroughness of cleaning, and effectively avoids the problem of localized stain residue caused by missed scraping areas.
[0088] refer to Figure 3 In one embodiment of this disclosure, the second cleaning unit 22 is configured to be disposed in the second region 202 adjacent to the first region 201. Due to the material characteristics of the second cleaning unit 22, while the second region 202 has a strong cleaning effect, it also has relatively poor sealing performance. If the second cleaning unit 22 is disposed on the outside of the second region 202, the outer ring area of the cleaning component 2 may not be able to stably adhere to the surface to be cleaned, thus reducing the scraping effect of the second cleaning unit 22. In this embodiment, since the second region 202 is located outside the first region 201 and the second cleaning unit 22 is arranged adjacent to the first region 201, the suction force of the sealing ring in the first region 201 can be used to make the scraping operation of the second cleaning unit 22 more stable.
[0089] In one embodiment of this disclosure, a first cleaning unit 21 is further provided in the second region 202 at a position away from the first region 201. Two types of cleaning units are provided in the second region 202: a second cleaning unit 22 located relatively close to the first region 201 (i.e., inside), and a first cleaning unit 21 located relatively far from the first region 201 (i.e., outside). The first region 201 is composed of the first cleaning unit 21, thus the first cleaning unit 21 is provided both inside and outside the second cleaning unit 22.
[0090] Specifically, the outer first cleaning unit 21 can preferentially contact the surface to be cleaned during the movement of the window cleaning robot to initially remove floating dust; the middle second cleaning unit 22 can scrape stubborn stains, soften the stains, and improve the cleaning effect; the inner first cleaning unit 21 can completely remove the softened stains. At the same time, when adsorbed onto the surface to be cleaned, the inner and outer first cleaning units 21 can all provide a sealing effect, thereby enhancing the overall fit between the second area 202 and the working surface, helping to maintain negative pressure stability, avoiding the problem of the adsorption seal being damaged by the setting of the second cleaning unit 22, and improving the safety of the window cleaning robot.
[0091] refer to Figure 3 In one embodiment of this disclosure, the second region 202 has a boundary line that intersects with the first region 201, and the outline of the second cleaning unit 22 is configured to form the boundary line. This disclosure uses the outline of the second cleaning unit 22 to define the boundary line between the first region 201 and the second region 202, thereby precisely dividing the two regions such that the second cleaning unit 22 is located in the second region 202 at the position closest to the first region 201.
[0092] Specifically, the second cleaning unit 22 can be composed of multiple scraping parts 221, which are arranged in a staggered pattern with adjacent scraping parts 221 at different distances from the inner contour of the ring, forming a toothed contour, so that the boundary line between the second region 202 and the first region 201 is toothed. Figure 3 As shown, the scraping part 221 can be rectangular, and multiple rectangular scraping parts 221 are arranged alternately. Adjacent scraping parts 221 can be disconnected or connected by a small amount of second fiber material, so that the second cleaning unit 22 is continuously arranged, facilitating gluing or sewing during the production process. The alternately arranged multiple scraping parts 221 allow the scraping trajectories of adjacent scraping parts 221 to complement each other, reducing blind spots in unidirectional scraping and thus achieving a stronger cleaning effect.
[0093] In one embodiment of this disclosure, a first cleaning unit 21 is provided between two adjacent scraping portions 221. When the cleaning component 2 is adsorbed onto the surface to be cleaned, the first cleaning unit 21 located between two adjacent scraping portions 221 forms a sealing ring to seal with the surface to be cleaned, thereby forming an annular seal on the outer periphery of the scraping portion 221 that is closer to the inner contour of the ring, further improving the sealing performance of the cleaning component 2.
[0094] Furthermore, in another embodiment of this disclosure, a first cleaning unit 21 is provided on the outer periphery of the scraping portion 221 located further away from the inner contour of the ring. When the cleaning component 2 is adsorbed onto the surface to be cleaned, the first cleaning unit 21 located on the outer periphery of all the scraping portions 221 forms a sealing ring and seals with the surface to be cleaned, thereby forming an annular seal on the outer periphery of all the scraping portions 221, further improving the sealing performance of the cleaning component 2.
[0095] The serrated boundary line formed by the second cleaning unit 22 provides a filling gap for the first cleaning unit 21, making the layout of the scraping part 221 and the first cleaning unit 21 filling the gap more compact. The first cleaning unit 21 can fully fill the gap between the scraping parts 221, thereby improving the sealing effect.
[0096] Specifically, adjacent scraping portions 221 are connected by a connecting portion, so that the second cleaning units 22 are continuously disposed in the second region 202. The connecting portion and the scraping portions 221 are made of the same material, thereby making the second cleaning units 22 have a continuous toothed shape. The two adjacent second cleaning units 22 and the connecting portion for connecting them have a semi-enclosed structure, thereby leaving a filling gap for the first cleaning units 21. When the cleaning member 2 is adsorbed onto the surface to be cleaned, at least a portion of the first cleaning units 21 adjacent to the connecting portion covers the connecting portion. Due to its material properties, the first cleaning units 21 can expand and deform to cover the connecting portion between adjacent scraping portions 221. In this way, the first cleaning units 21 can be disposed all around the scraping portion 221, thereby further enhancing the sealing effect.
[0097] Example 3 This embodiment also provides a window cleaning robot and cleaning component 2. The main difference from Embodiment 1 is that the specific structure of cleaning component 2 is different. Apart from cleaning component 2, the other structures and working principles of the window cleaning robot are completely consistent with Embodiment 1, and will not be described again in this embodiment.
[0098] refer to Figure 4The cleaning unit 2 in this embodiment includes a flexible first cleaning unit 21 and a rigid second cleaning unit 22. It should be noted that flexibility and rigidity are relative terms. As described in Embodiment 1, the first cleaning unit 21 is made of a first fiber material (such as fluff fiber), and the second cleaning unit 22 is made of a second fiber material (such as PP fiber, polyester fiber, or polyester film fiber). The hardness of the second fiber material is greater than that of the first fiber material.
[0099] The second cleaning unit 22 has a mesh structure and is disposed on the first cleaning unit 21. The second cleaning unit 22 includes a mesh outline and mesh openings formed within the mesh outline. At least a portion of the first cleaning unit 21 is exposed through the mesh openings, and the first cleaning unit 21 fills the mesh openings when the window cleaning robot adheres to the surface to be cleaned. Specifically, the first cleaning unit 21 can be a soft cloth, and the second cleaning unit 22 covers at least a portion of the surface of the first cleaning unit 21. The mesh outline of the second cleaning unit 22 can be pressed onto the first cleaning unit 21, or it can be embedded between the fibers of the first cleaning unit 21. The second cleaning unit 22 can be made of a rigid fibrous material, thereby providing a scraping effect and enhancing the cleaning effect on stubborn stains.
[0100] Due to the material characteristics of the second cleaning unit 22, the second area 202 has a relatively poor sealing performance while having a strong cleaning effect. Therefore, setting the second cleaning unit 22 on the cleaning component 2 may damage the airtightness, causing the negative pressure adsorption stability of the window cleaning robot to decrease, which in turn creates the risk of falling off during high-altitude operations, threatening the safety of users' property and living environment.
[0101] To solve the above problems, this embodiment sets the second cleaning unit 22 as a mesh structure, so that the first cleaning unit 21 can be exposed through the mesh. This avoids the second cleaning unit 22 from completely covering the first cleaning unit 21, ensuring that the first cleaning unit 21 has a sufficiently large contact area with the surface to be cleaned, thereby forming a sealing structure around the mesh outline and avoiding the problem of the adsorption seal being damaged by setting the second cleaning unit 22.
[0102] The mesh outline of the second cleaning unit 22 can be made using a weaving process, with a uniformly distributed mesh structure. This ensures that the contact points between the first cleaning unit 21 passing through the mesh and the surface to be cleaned are even and dense, resulting in a more balanced distribution of sealing pressure and thus reducing negative pressure leakage. Specifically, the first cleaning unit 21 is partially exposed through the mesh. When the window cleaning robot adheres to the surface to be cleaned, the first cleaning unit 21 can fill the mesh, thereby filling the internal space of the mesh and at least part of the gaps between adjacent meshes, thus achieving a sealing effect and improving the safety of the window cleaning robot.
[0103] In one embodiment of this disclosure, the mesh is constructed as a circle or a polygon (such as a triangle, square, rhombus, pentagon, hexagon, etc.), preferably, as shown below. Figure 4 As shown, the mesh is constructed in hexagonal shapes, and the second cleaning unit 22 has a honeycomb mesh structure. As a highly efficient geometric structure, the hexagon provides stronger structural support with the same amount of material, making the mesh structure more robust and less prone to deformation or tearing during scraping, thus improving the durability of the second cleaning unit 22. Furthermore, the polygonal shape of the hexagonal mesh allows for a more uniform stress distribution between adjacent meshes. When scraping the working surface, the forces on each part of the second cleaning unit 22 are more balanced, reducing excessive localized wear and extending its service life.
[0104] In one embodiment of this disclosure, the mesh diameter is 2-6 mm. This provides sufficient rigidity to the mesh structure of the second cleaning unit 22, enabling it to effectively scrape away stubborn stains (such as water stains, crusts, and hardened dust) from the surface to be cleaned, while ensuring that the first cleaning unit 21 can be exposed through the mesh to ensure a sealing effect. It is understood that the mesh size should not be too small, otherwise the first cleaning unit 21 will have difficulty passing through; similarly, the mesh size should not be too large, otherwise the amount of material used for the mesh outline will be insufficient, reducing rigidity and thus decreasing the scraping effect of the second cleaning unit 22. Preferably, the mesh diameter can be set to 3 mm.
[0105] In one embodiment of this disclosure, the first cleaning unit 21, exposed through a single mesh, comprises at least two needle-like fibers, thereby ensuring adequate filling of the first cleaning unit 21. When the window cleaning robot adheres to the surface to be cleaned, the fibers of the first cleaning unit 21 can fully extend and interweave, tightly filling the mesh space to form a continuous sealing layer without obvious gaps, effectively preventing negative pressure leakage and ensuring adsorption stability. When designing the mesh size of the second cleaning unit 22, it should be ensured that its size is sufficient for at least two needle-like fibers to pass through.
[0106] In one embodiment of this disclosure, reference is made to Figure 2 The second cleaning unit 22 is configured to be disposed on a portion of the first cleaning unit 21, and the first cleaning unit 21 not covered by the second cleaning unit 22 is configured to be a continuously arranged annular structure. This results in the first cleaning unit 21 covered by the second cleaning unit 22 forming a continuous annular structure, with no break in the contact between the first cleaning unit 21 and the surface to be cleaned, and the negative pressure can be evenly applied to the entire annular structure, thereby forming a stable and uniform sealing effect.
[0107] In one embodiment of this disclosure, the second cleaning unit 22 is located at the front end of the cleaning component 2, and / or, the second cleaning unit 22 is located at the rear end of the cleaning component 2. Specifically, in this embodiment, two second cleaning units 22 are provided, located on the front and rear sides of the cleaning component 2 respectively, and symmetrically arranged on the front and rear sides about the centerline of the cleaning component 2. This disclosure sets the arrangement of the second cleaning units 22 in conjunction with the travel direction of the window cleaning robot. The second cleaning unit 22 located on the front side can scrape the stubborn stains in the area to be cleaned in advance, softening the stains so that the subsequent first cleaning unit 21 only needs to clean the softened loose stains, reducing the cleaning difficulty and improving the cleaning efficiency; the second cleaning unit 22 located on the rear side can perform a second scraping on the cleaned area to remove residual water stains and impurities, optimizing the cleaning effect.
[0108] In one embodiment of this disclosure, the second cleaning unit 22 is configured to cover the travel path of the first cleaning unit 21 in either the forward or backward direction. Thus, regardless of whether the window cleaning robot is moving forward or backward, every cleaning area along the travel path of the first cleaning unit 21 can be spatially covered by the second cleaning unit 22. This ensures comprehensive coverage of the scraping function, eliminates blind spots where the second cleaning unit 22 cannot perform scraping cleaning, improves the uniformity and thoroughness of cleaning, and effectively avoids the problem of localized stain residue caused by missed scraping areas.
[0109] Application scenarios In home environments, window cleaning robots are used to clean the glass windows of high-rise buildings. This cleaning environment places high demands on the cleaning effectiveness and suction performance of the robot. The robot's body 1 is equipped with a cleaning component 2, which is used to clean the glass window surface. This component can be a cloth placed on the side of the body 1 facing the surface to be cleaned, and it has a designated cleaning area.
[0110] The cleaning area includes a first area 201 and a second area 202. The first area 201 is located on the outer periphery of the inner ring contour and forms a sealing ring when it is adsorbed onto the surface to be cleaned. The adsorption component is used to provide adsorption force for the first area 201, thereby creating a negative pressure between the first area 201 and the glass window surface. This utilizes the air pressure difference to firmly adsorb the window cleaning robot onto the glass window surface, preventing it from falling off due to gravity when working at height.
[0111] A first cleaning unit 21 is provided in the first region 201, and the first region 201 is configured to seal against the glass window surface through the first cleaning unit 21. A second cleaning unit 22 is provided in the second region 202, which partially overlaps with the first region 201. The second cleaning unit 22 is configured to enclose and form a preset gap 23, and a portion of the first cleaning unit 21 is configured to protrude through the preset gap 23 to seal against the glass window surface. This increases the contact area between the first cleaning unit 21 and the surface to be cleaned, improving the sealing effect of the cleaning component 2.
[0112] Specifically, the first cleaning unit 21 is a cloth made of fluffy fibers, and the second cleaning unit 22 is a mesh structure made of PP fibers. This mesh structure has evenly distributed diamond-shaped mesh openings, which are the aforementioned pre-set gaps 23. The second cleaning unit 22 is adhered to the first cleaning unit 21, and some of the fluffy fibers of the first cleaning unit 21 protrude through the mesh openings. The first cleaning unit 21 provides the primary cleaning effect, removing dirt from the glass window surface through wiping; the second cleaning unit 22 can scrape the surface to be cleaned, thereby removing stubborn stains.
[0113] This disclosure effectively balances the cleaning effect and sealing performance of the window cleaning robot by dividing the sealing ring on the cleaning component 2 into a first region 201 and a second region 202. Specifically, the first region 201 only has a first cleaning unit 21. The first region 201 achieves a stable sealing fit with the glass window surface through the first cleaning unit 21, forming a reliable negative pressure adsorption effect with the adsorption component, reducing the risk of the window cleaning robot falling off during high-altitude operations and ensuring safety. The second region 202 is provided with a second cleaning unit 22, which can perform a scraping action to enhance the cleaning effect of stubborn stains. The second region 202 partially overlaps with the first region 201, and the preset gap 23 enclosed by the second cleaning unit 22 allows part of the first cleaning unit 21 to pass through, thereby maintaining the sealing of the area around the second cleaning unit 22 and preventing the adsorption seal from being damaged by the addition of hard wire-like structures.
