Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, specifically to a planar cleaning robot and cleaning system. Background Technology

[0002] To clean window surfaces, inefficient and dangerous manual window cleaning has gradually been replaced by efficient and safe machines, leading to the development of surface cleaning robots. Surface cleaning robots need to adhere firmly to the surface to be cleaned during operation. The stability of this adhesion is crucial for the machine's normal operation and safety. The assembly precision of the vacuum source directly affects the formation of the vacuum chamber; therefore, the assembly precision of the vacuum source is a key indicator of adhesion stability. Summary of the Invention

[0003] In view of this, the present invention aims to provide a planar cleaning robot that can improve the assembly accuracy of the vacuum source, thereby enhancing the robot's adsorption stability.

[0004] This utility model provides a planar cleaning robot for cleaning a planar surface, comprising: A vacuum assembly includes a vacuum source and a vacuum base. The vacuum source is sealed to the vacuum base. The vacuum base has an annular mounting groove on the side adjacent to the vacuum source, and the vacuum source has an annular protrusion on the side adjacent to the vacuum base. The annular protrusion is located within the annular mounting groove. The vacuum source has a first chamber, and the vacuum base has a second chamber. The second chamber is connected to the first chamber and the outside. The vacuum source is used to create a vacuum space between the first chamber, the second chamber and the surface to be cleaned so that the flat cleaning robot can be attached to the surface to be cleaned.

[0005] This design utilizes annular protrusions and annular mounting grooves to achieve assembly and positioning between the vacuum source and the vacuum base, thereby improving the assembly accuracy of the vacuum source and ensuring the airtightness between the vacuum source and the vacuum base.

[0006] In some embodiments, the planar cleaning robot further includes a cleaning component and a main body base. The vacuum base is located inside the main body base, with its outer surface in contact with the inner surface of the main body base. The side of the vacuum base away from the vacuum source extends at least partially out of the main body base. The cleaning component is located on the side of the vacuum base away from the vacuum source and is connected to the side of the main body base away from the vacuum source. The cleaning component seals the vacuum space while performing the cleaning function, and it is floatable along a direction orthogonal to the plane to be cleaned.

[0007] This configuration allows the cleaning components to both perform cleaning tasks and seal the vacuum space, ensuring the flat cleaning robot can stably adhere to the surface to be cleaned. The floating arrangement of the cleaning components allows for better attachment to the surface, guaranteeing cleaning effectiveness while also improving the stability of adsorption within the vacuum space.

[0008] In some embodiments, the vacuum base has a first annular sealing groove on the side adjacent to the vacuum source, and the vacuum source has a first sealing ring on the side adjacent to the vacuum base, with the first sealing ring located within the first annular sealing groove.

[0009] This configuration not only provides installation space for the first sealing ring using the first annular sealing groove, but also improves the sealing performance between the vacuum source and the vacuum base by utilizing the cooperation between the first annular sealing groove and the first sealing ring.

[0010] In some embodiments, the first sealing ring is an elastic sealing ring, and / or, The first sealing ring is an elastic sealing ring, and the first sealing ring is integrally formed with the vacuum source.

[0011] This configuration, which makes the first sealing ring an elastic sealing ring, not only ensures that the first sealing ring is stably attached to the inner wall of the first annular sealing groove, but also provides room for the cleaning component to float up and down, thus ensuring the cleaning quality and the sealing effect of the cleaning component on the vacuum space.

[0012] In some embodiments, the vacuum base is a flexible base. This flexible base provides allowance for the cleaning components to move vertically, further ensuring cleaning quality and the sealing effect of the cleaning components within the vacuum space.

[0013] In some embodiments, the cleaning assembly includes a fixing component and a cleaning component, the fixing component being adapted to be connected to the robot body of the planar cleaning robot and having a sealed fit with the vacuum base, and the cleaning component being connected to the fixing component.

[0014] Using fixed components can improve the stability of the support for the cleaning components, preventing changes in the position of the cleaning components from affecting the cleaning and sealing effect of the vacuum space.

[0015] In some embodiments, the vacuum base has a second annular sealing groove on the side adjacent to the fixing component, and the fixing component has a second sealing ring on the side adjacent to the vacuum base, the second sealing ring being located within the second annular sealing groove.

[0016] This configuration not only provides installation space for the second sealing ring using the second annular sealing groove, but also improves the sealing performance between the vacuum source and the vacuum base by utilizing the cooperation between the second annular sealing groove and the second sealing ring.

[0017] In some embodiments, the second sealing ring is integrally formed with the cleaning component, and / or the second sealing ring is an elastic sealing ring.

[0018] This configuration, which makes the second sealing ring an elastic sealing ring, not only ensures that the second sealing ring is stably attached to the inner wall of the second annular sealing groove, but also provides room for the cleaning component to float up and down, thus ensuring the cleaning quality and the sealing effect of the cleaning component on the vacuum space.

[0019] In some embodiments, the fixing component has a plurality of support ribs on one end face adjacent to the cleaning component. The support ribs are located at the connection between the fixing component and the cleaning component, and the plurality of support ribs are arranged at intervals in the width direction of the fixing component.

[0020] This design, utilizing support ribs, improves the stability of the fixed component's support for the cleaning component, thereby ensuring the seal between the fixed and cleaning components and ultimately enhancing the airtightness of the entire vacuum space.

[0021] In some embodiments, the fixing component has a plurality of third grooves evenly distributed on one end face of the side adjacent to the cleaning component, and the third grooves are located between two adjacent support ribs.

[0022] With this configuration, when a negative pressure is generated in the vacuum space, the negative pressure airflow forms a vortex at the third groove, which can improve the adsorption force of the fixed component on the cleaning component, thereby ensuring the airtightness between the fixed component and the cleaning component.

[0023] In some embodiments, the planar cleaning robot further includes a main body base, the vacuum assembly is located within the main body base, and the cleaning assembly is connected to the main body base. The vacuum assembly is connected to the main body base, or the vacuum assembly is connected to the cleaning assembly.

[0024] This design, by incorporating a main base, enhances the structural strength of the planar cleaning robot and improves the connection stability between the vacuum and cleaning components.

[0025] In some embodiments, the vacuum base extends at least partially beyond the main body base on the side away from the vacuum source. This allows a portion of the vacuum space to protrude outward, enabling the robot body to adhere more effectively to the surface to be cleaned.

[0026] In some embodiments, the planar cleaning robot further includes a walking unit connected to the main body base, the walking unit being used to move the main body base on the plane to be cleaned.

[0027] In this way, the walking unit allows the planar cleaning robot to move freely on the surface to be cleaned, improving cleaning efficiency and quality.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] In the related technology, the blower, i.e., the vacuum source 1, of the planar cleaning robot is fixed to and sealed to the main body base 6, which has a cavity. A sealing element exists between the main body base 6 and the cloth holder, the cloth holder is fastened to the main body base 6, and the cloth adheres to the cloth holder. The main body base 6, the cloth holder, the sealing element, the cloth, and the surface to be cleaned together form a vacuum negative pressure chamber. In other words, the vacuum negative pressure chamber is formed by the main body base 6, the blower, the blower base, the cloth holder, the cloth, and the surface to be cleaned. Therefore, seals need to be formed between the blower and the blower base, between the blower and the main body base 6, between the blower base and the main body base 6, between the sealing element and the main body base 6, between the sealing element and the cloth holder, between the cloth holder and the cloth, and between the cloth and the surface to be cleaned. The components of the sealed vacuum negative pressure chamber are complex; if there are unstable connections, the sealing performance of the vacuum negative pressure chamber can be easily affected, thus affecting the adhesion between the planar cleaning robot and the surface to be cleaned.

[0040] To address the aforementioned problems, this utility model provides a planar cleaning robot for cleaning a surface to be cleaned. The robot includes a vacuum assembly 100 and a cleaning assembly 400. The vacuum assembly 100 includes a vacuum source 1 and a vacuum base 2. The vacuum source 1 and the vacuum base 2 are sealed together. The vacuum source 1 has a first chamber 101, and the vacuum base 2 has a second chamber 201. The second chamber 201 connects the first chamber 101 to the outside. The vacuum source 1 forms a vacuum space 300 between the first chamber 101, the second chamber 201, and the surface to be cleaned, allowing the planar cleaning robot to adhere to the surface.

[0041] See Figure 1 and Figure 2As shown, the planar cleaning robot also includes a housing 200, a vacuum assembly 100 installed inside the housing 200, and a portion of the cleaning assembly 400 exposed outside the housing 200. For example, when the housing 200 is placed vertically, the vacuum assembly 100 is located above the cleaning assembly 400, and the bottom of the cleaning assembly 400 is exposed outside the housing 200.

[0042] For example, the vacuum source 1 can be a vacuum blower, which includes a housing, a motor (not shown) and a fan blade (not shown). The first chamber 101 is located inside the housing, the fan blade is located inside the first chamber 101, the motor is located outside the housing, and the output shaft of the motor is connected to the fan blade. The rotation of the motor can drive the fan blade to rotate inside the first chamber 101, thereby generating negative pressure inside the first chamber 101.

[0043] It should be noted that the vacuum source 1 can also be a vacuum pump. The vacuum pump has a first chamber 101 inside, which is connected to the second chamber 201 to form a vacuum space 300.

[0044] The vacuum base 2 has a second chamber 201. The upper end of the second chamber 201 is connected to the first chamber 101, and the lower end of the second chamber 201 is connected to the outside. It should be noted that when the first chamber 101 generates negative pressure, since the second chamber 201 is connected to the first chamber 101, the second chamber 201 is also a negative pressure space. The first chamber 101 and the second chamber 201 form a vacuum space 300.

[0045] See Figure 2 As shown, the lower end of the vacuum source 1 extends into the second chamber 201. In other words, the first chamber 101 and the second chamber 201 partially overlap, thereby ensuring that the negative pressure generated by the first chamber 101 can be stably transferred to the second chamber 201, so that the negative pressure generated by the entire vacuum space 300 is more uniform and stable, and thus the planar cleaning robot can be better adsorbed on the surface to be cleaned.

[0046] Additionally, it should be noted that when the planar cleaning robot adheres to the surface to be cleaned under the negative pressure generated by vacuum source 1, the robot exerts pressure on the surface. Therefore, the surface can seal the outlet of the vacuum space 300. For example, when the planar cleaning robot moves along... Figure 1 When placed in the up-down direction as shown, the surface to be cleaned seals the bottom of the vacuum space 300.

[0047] Optionally, the upper end of the vacuum base 2 has an annular mounting groove 204, which is located outside the first annular sealing groove 202 and is arranged concentrically with the first annular sealing groove 202. The lower end face of the vacuum source 1 has an annular protrusion 103, which extends in the vertical direction. When the vacuum source 1 is connected to the vacuum base 2, the annular protrusion 103 is inserted into the annular mounting groove 204. The annular protrusion 103 and the annular mounting groove 204 can not only improve the assembly accuracy between the vacuum source 1 and the vacuum base 2, but also further enhance the sealing performance between them.

[0048] The cleaning component 400 is located on the side of the vacuum base 2 away from the vacuum source 1. The cleaning component 400 seals the vacuum space 300 while performing the cleaning function.

[0049] See Figure 1 and Figure 2 As shown, when the planar cleaning robot is placed in the vertical direction, the cleaning component 400 is located at the bottom of the vacuum component 100, and the lower end face of the cleaning component 400 is attached to the plane to be cleaned. At this time, the cleaning component 400 can also be used as a seal at the bottom of the vacuum space 300 while performing the cleaning function.

[0050] This configuration utilizes the first chamber 101 within the vacuum source 1 and the second chamber 201 within the vacuum base 2 to form a vacuum chamber. The vacuum chamber is then sealed by the surface to be cleaned to form a vacuum space 300, thereby adsorbing the planar robot onto the surface to be cleaned. By adding the cleaning component 400, it can not only perform the cleaning function but also serve as a seal for the vacuum space 300. Compared to the vacuum space 300 in related technologies, which is formed by the main base, vacuum source 1, vacuum base 2, cleaning component 400, and surface to be cleaned, the vacuum space 300 in this application is formed by the vacuum source 1, vacuum base 2, cleaning component 400, and surface to be cleaned. The formation of the vacuum space 300 eliminates the need for the main base, and there is no need to seal between the vacuum source 1 and the main base 6, or between the vacuum base 2 and the main base 6. This reduces the number of seals, shortens the sealing path of the vacuum space 300, reduces the risk of leakage, and thus improves the robot's adsorption stability.

[0051] In some embodiments, the planar cleaning robot further includes a main body base 6, a vacuum assembly 100 located inside the main body base 6, a cleaning assembly 400 connected to the main body base 6, or a vacuum assembly 100 connected to the cleaning assembly 400.

[0052] See Figure 1 and Figure 2As shown, the main body base 6 is installed below the housing 200, and the main body base 6 is detachably connected to the housing 200. For example, the main body base 6 and the housing 200 are detachably connected by a snap-fit ​​or magnetic attraction, or the main body base 6 and the housing 200 are connected by bolts. An installation space is formed between the main body base 6 and the housing 200, the vacuum assembly 100 is located in the installation space, and the upper end of the cleaning assembly 400 is connected to the main body base 6.

[0053] Optionally, the vacuum assembly 100 is detachably connected to the main body base 6. For example, the vacuum base 2 is snapped into the main body base 6, and the vacuum source 1 is connected to the vacuum base 2 and thus mounted on the main body base 6.

[0054] Optionally, the vacuum assembly 100 can also be connected to the cleaning assembly 400. For example, the vacuum base 2 is connected to the cleaning assembly 400, and the vacuum source 1 is connected to the vacuum base 2, so that the vacuum source 1 is mounted on the cleaning assembly 400.

[0055] This configuration, by setting the main base 6, not only provides installation space for the vacuum component 100, the cleaning component 400 and other components, but also improves the structural strength of the planar cleaning robot, which is beneficial to improving the connection stability of the vacuum component 100 and the cleaning component 400.

[0056] In some embodiments, the side of the vacuum base 2 away from the vacuum source 1 extends at least partially out of the main body base 6.

[0057] See Figure 2 As shown, the lower end face of the vacuum base 2 extends out of the main body base 6. In other words, the lower part of the vacuum base 2 is exposed outside the main body base 6. In this way, part of the vacuum space 300 can be protruded outward, which allows the robot body to be better adsorbed on the surface to be cleaned.

[0058] In some embodiments, the planar cleaning robot further includes a walking unit 500, which is connected to the main body base 6 and is used to drive the main body base 6 to move on the plane to be cleaned.

[0059] See Figure 1 As shown, the walking unit 500 is installed inside the housing 200 and is connected to the main body base 6. There are two walking units 500, which are arranged symmetrically in the front-rear direction or the left-right direction of the main body base 6. It should be noted that the vacuum assembly 100 is located between the two walking units 500.

[0060] For example, the walking unit 500 includes a motor and a track. The motor drives the track to rotate. After the robot body adheres to the surface to be cleaned, the outer surface of the track can contact the surface. To increase the friction between the track and the surface, the track can be a rubber track with grooves or patterns. Using two walking units 500 allows the flat cleaning robot to move freely on the surface to be cleaned, improving cleaning efficiency and quality.

[0061] In some embodiments, the cleaning component 400 may float in a direction orthogonal to the plane to be cleaned.

[0062] It should be noted that, see Figure 2 As shown, when the planar cleaning robot is placed in the vertical direction, the surface to be cleaned is located below the planar cleaning robot, the lower end of the cleaning component 400 is in contact with the surface to be cleaned, and the cleaning component 400 can float in the vertical direction. It should be noted that the floating of the cleaning component 400 in the vertical direction means that the cleaning component 400 has displacement in the vertical direction. In other words, the position of the cleaning component 400 in the vertical direction can change.

[0063] With this configuration, the cleaning component 400 can be floated, which allows it to adhere better to the surface to be cleaned. The adaptive bonding technology improves the cleaning effect, enhances the adaptability to complex surfaces to be cleaned, achieves uniform pressure cleaning, and optimizes cleaning efficiency. While ensuring the cleaning effect, it can also improve the stability of the vacuum space 300 adsorption.

[0064] Furthermore, the floating cleaning component 400 can automatically adjust its fit according to the unevenness of the surface to be cleaned. When the robot encounters tiny bumps or depressions on the surface, the floating structure ensures that the cleaning component 400 fits tightly against the surface, guaranteeing that every area is effectively cleaned. This adaptive fitting technology significantly improves the thoroughness of cleaning and avoids cleaning dead spots caused by uneven surfaces.

[0065] The surface to be cleaned may also have various irregular textures or stains, and the floating cleaning component 400 can better adapt to these variations. For example, when cleaning areas with stickers or frosted finishes, the floating cleaning component 400 ensures contact with the surface, thereby effectively removing stains. This adaptability allows the robot to be used in a wider range of scenarios, meeting the needs of different users.

[0066] The floating cleaning component 400 maintains uniform pressure during the cleaning process. As the robot moves, the floating cleaning component 400 adjusts the pressure of the cloth according to the surface to be cleaned, ensuring consistent cleaning intensity in each area. This uniform pressure avoids differences in cleaning effect and adhesion at different locations caused by uneven pressure, improving overall cleaning quality and adhesion stability.

[0067] The design of the floating cleaning component 400 also improves the robot's cleaning efficiency. Because the cleaning cloth adheres closely to the surface to be cleaned, the robot can complete the cleaning task faster, while reducing repetitive cleaning caused by the cleaning component 400 separating from the surface. This efficient cleaning saves users time and effort, improving the user experience.

[0068] In some embodiments, the vacuum base 2 is provided with a first annular sealing groove 202 on the side adjacent to the vacuum source 1, and the vacuum source 1 is provided with a first sealing ring 102 on the side adjacent to the vacuum base 2, and the first sealing ring 102 is located in the first annular sealing groove 202.

[0069] See Figure 3 As shown, when the vacuum base 2 is placed vertically, the vacuum source 1 is located above the vacuum base 2. The upper surface of the vacuum base 2 is provided with a first annular sealing groove 202, which is arranged in a ring along the circumference of the vacuum base 2. A first sealing ring 102 is located on the lower surface of the vacuum source 1. The width of the first sealing ring 102 is slightly smaller than the width of the first annular sealing groove 202, allowing the first sealing ring 102 to be installed more smoothly into the first annular sealing groove 202. This arrangement provides installation space for the first sealing ring 102 using the first annular sealing groove 202, and also improves the sealing performance between the vacuum source 1 and the vacuum base 2 through the cooperation of the first annular sealing groove 202 and the first sealing ring 102.

[0070] In some embodiments, the first sealing ring 102 is an elastic sealing ring, and / or the first sealing ring 102 is integrally formed with the vacuum source 1.

[0071] For example, the first sealing ring 102 is a rubber sealing ring. Optionally, the first sealing ring 102 is integrally formed with the vacuum source 1. In this configuration, the first sealing ring 102 is set as an elastic sealing ring. Since the negative pressure generated by the vacuum source 1 can cause the flat cleaning robot to adhere to the surface to be cleaned, the flat cleaning robot exerts pressure on the surface to be cleaned. When the first sealing ring 102 is an elastic sealing ring, after the pressure is transmitted to the first sealing ring 102, it can not only ensure that the first sealing ring 102 is stably attached to the inner wall of the first annular sealing groove 202, but also provide the cleaning component 400 with a margin for vertical floating, thus ensuring the cleaning quality and the sealing effect of the cleaning component 400 on the vacuum space 300.

[0072] In some embodiments, the vacuum base 2 is provided with a second annular sealing groove 203 on the side adjacent to the cleaning component 400, and the cleaning component 400 is provided with a second sealing ring 401 on the side adjacent to the vacuum base 2, and the second sealing ring 401 is located in the second annular sealing groove 203.

[0073] See Figure 3 and Figure 4 As shown, the cleaning component 400 includes a fixing component 4 and a cleaning component 5. The fixing component 4 is adapted to be connected to the robot body of the planar cleaning robot, and the fixing component 4 is sealed to the vacuum base 2. The cleaning component 5 is connected to the fixing component 4.

[0074] For example, the fixing component 4 is installed below the main body base 6. The fixing component 4 can be detachably connected to the main body base 6, for example, by means of a snap-fit ​​or magnetic attraction. The fixing component 4 can improve the stability of the support for the cleaning component 5, and prevent the position of the cleaning component 5 from changing, which would affect the cleaning and sealing effect of the vacuum space 300.

[0075] The fixed component 4 is provided with two through slots 403, and two walking units 500 are installed in the positions of the two through slots 403 respectively, and the tracks in the walking units 500 are located in the through slots 403.

[0076] The fixed component 4 is sealed to the vacuum base 2 at the contact point. The vacuum base 2 is provided with a second annular sealing groove 203 on the side of the fixed component 4 in the cleaning assembly 400, that is, the lower end face of the vacuum base 2 is provided with a second annular sealing groove 203. The fixed component 4 in the cleaning assembly 400 is provided with a second sealing ring 401 on the side of the vacuum base 2, that is, the upper end face of the vacuum base 2 is provided with a second sealing ring 401. The second sealing ring 401 is located in the second annular sealing groove 203.

[0077] See Figure 3 As shown, when the vacuum base 2 is placed vertically, the cleaning component 400 is located below the vacuum base 2. The lower end face of the vacuum base 2 is provided with a second annular sealing groove 203, which is arranged in a ring shape along the circumference of the vacuum base 2. The second sealing ring 401 is located on the upper end face of the fixing component 4. The width of the second sealing ring 401 is slightly smaller than the width of the second annular sealing groove 203, allowing the second sealing ring 401 to be installed more smoothly into the second annular sealing groove 203. This arrangement provides installation space for the second sealing ring 401 using the second annular sealing groove 203, and also improves the sealing performance between the vacuum source 1 and the vacuum base 2 through the cooperation of the second annular sealing groove 203 and the second sealing ring 401.

[0078] In some embodiments, the second sealing ring 401 is integrally formed with the cleaning component 400, and / or the second sealing ring 401 is an elastic sealing ring.

[0079] Specifically, see Figure 2 As shown, the second sealing ring 401 is located on the upper end face of the fixed component 4. Optionally, the second sealing ring 401 is integrally formed with the fixed component 4, or the second sealing ring 401 is an elastic sealing ring. With this configuration, the second sealing ring 401 is set as an elastic sealing ring. Since the negative pressure generated by the vacuum source 1 can make the flat cleaning robot adhere to the surface to be cleaned, the flat cleaning robot exerts pressure on the surface to be cleaned. When the second sealing ring 401 is an elastic sealing ring, after the pressure is transmitted to the second sealing ring 401, it can not only ensure that the second sealing ring 401 is stably attached to the inner wall of the second annular sealing groove 203, but also provide the cleaning component 400 with a margin for vertical floating, thus ensuring the cleaning quality and the sealing effect of the cleaning component 400 on the vacuum space 300.

[0080] In some embodiments, the cleaning component 5 can be a rag, and the fixing component 4 can be a rag holder. The cleaning component 5 and the fixing component 4 are detachably connected. For example, the cleaning component 5 and the fixing component 4 can be detachably connected by means of snaps or magnetic attraction.

[0081] It should be noted that the cleaning component 5 can also be a flat surface such as a cleaning sponge for cleaning.

[0082] In some embodiments, the vacuum base 2 is an elastic base.

[0083] For example, if the vacuum base 2 is a rubber base, the negative pressure generated by the vacuum source 1 can cause the flat cleaning robot to adhere to the surface to be cleaned. The flat cleaning robot exerts pressure on the surface to be cleaned. When the vacuum base 2 is an elastic base, after the pressure is transmitted to the vacuum base 2, the vacuum base 2 is squeezed and contracted. This not only makes the contact between the vacuum base 2 and the vacuum source 1 tighter, ensuring the airtightness between the first chamber 101 and the second chamber 201, but also shortens the path length of the vacuum space 300. In other words, when the robot body is placed in the vertical direction, the vacuum base 2 is squeezed and contracted, and the dimension of the vacuum space 300 in the vertical direction will be shortened. Since the propagation path of the gas in the negative pressure space is reduced, the adsorption force on the surface to be cleaned is improved.

[0084] In this way, the flexible base can provide the cleaning component 400 with room for vertical movement, further ensuring the cleaning quality and the sealing effect of the cleaning component 400 on the vacuum space 300.

[0085] In some embodiments, the vacuum base 2 has a filter plate 3 on the side adjacent to the cleaning component 400. The filter plate 3 has a plurality of filter holes 301, which are evenly distributed on the end face of the vacuum base 2 adjacent to the cleaning component 400. The filter holes 301 connect the second chamber 201 to the outside.

[0086] See Figure 3 As shown, the filter plate 3 is located at the bottom of the vacuum base 2. In other words, the filter plate 3 is located at the outlet of the second chamber 201. Multiple filter holes 301 are evenly distributed on the filter plate 3, and the filter holes 301 connect the second chamber 201 with the outside.

[0087] By setting up a filter plate 3 and opening filter holes 301 on the filter plate 3, not only can the filter plate 3 prevent external impurities from entering the vacuum base 2 and vacuum source 1, improving the operational stability and service life of the vacuum source 1, but it can also maintain the adsorption stability of the vacuum space 300. By opening multiple filter holes 301, the suction force generated by the vacuum space 300 can also be distributed more evenly, thereby ensuring the uniformity of the adsorption force distribution and allowing the robot body to be better adsorbed onto the surface to be cleaned.

[0088] Optionally, the filter plate 3 and the vacuum base 2 are integrally formed. For example, when the vacuum base 2 is a rubber base, the filter plate 3 and the vacuum base 2 are integrally injection molded. The integral forming of the filter plate 3 and the vacuum base 2 can reduce the number of parts, reduce the risk of seal failure, and thus ensure the stability of the robot body adsorbed on the surface to be cleaned.

[0089] In some embodiments, the fixing component 4 is provided with a plurality of support ribs 7 on one end face adjacent to the cleaning component 5. The support ribs 7 are located at the connection between the fixing component 4 and the cleaning component 5, and the plurality of support ribs 7 are arranged at intervals in the width direction of the fixing component 4.

[0090] See Figure 6 As shown, the support ribs 7 are distributed at the connection between the fixing component 4 and the cleaning component 5, and adjacent support ribs 7 are arranged parallel to each other. The multiple support ribs 7 are divided into four columns, and the four columns of support ribs 7 are arranged at intervals in the circumference of the fixing component 4. In other words, support ribs 7 are provided in the front, back, left, and right directions of the fixing component 4, and each column of support ribs 7 contains the same number of support ribs 7.

[0091] It should be noted that the lower end face of the support rib 7 is flush with the lower end face of the fixing component 4. In other words, the support rib 7 is recessed upwards and located in the recessed area. By arranging the lower end face of the support rib 7 flush with the lower end face of the fixing component 4, the contact area between the cleaning component 5 and the fixing component 4 can be maintained, thereby ensuring the connection stability between the cleaning component 5 and the fixing component 4, and thus ensuring the sealing between the fixing component 4 and the cleaning component 5, thereby improving the airtightness of the entire vacuum space 300.

[0092] Furthermore, by utilizing the gaps between the support ribs 7, the contact area between the vacuum space 300 and the cleaning component 5 can be increased, thereby ensuring the sealing of the vacuum space 300.

[0093] Optionally, the support rib 7 and the fixing part 4 are integrally formed. For example, when the fixing part 4 is an injection molded part, the support rib 7 and the fixing part 4 are integrally injection molded. The integral forming of the support rib 7 and the fixing part 4 can improve the structural strength of the support rib 7.

[0094] In some embodiments, a plurality of third grooves 402 are evenly distributed on one end face of the fixing member 4 adjacent to the cleaning member 5, and the third grooves 402 are located between two adjacent support ribs 7.

[0095] For example, see Figure 6 As shown, the third groove 402 is a circular hole, and multiple third grooves 402 are provided between two adjacent support ribs 7. The multiple third grooves 402 located between two adjacent support ribs 7 are evenly spaced along the length direction of the support ribs 7.

[0096] Optionally, the number of third grooves 402 between two adjacent support ribs 7 is the same; for example, the number of third grooves 402 between two adjacent support ribs 7 is three.

[0097] A third groove 402 is provided between two adjacent support ribs 7. When the negative pressure airflow generated by the vacuum source 1 enters the gap between the two adjacent support ribs 7, the airflow will form a vortex at the third groove 402, which can improve the adsorption force of the fixing component 4 on the cleaning component 5, thereby ensuring the airtightness between the fixing component 4 and the cleaning component 5.

[0099] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications or equivalent substitutions made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
