Description

[Technical Field]

[0001] This application belongs to the field of household appliance technology, specifically relating to a sealing structure for a window cleaning machine cloth holder. [Background Technology]

[0002] In existing technologies, the structure of a cloth holder typically involves the cloth directly contacting the holder. However, during machine operation in various environments, it has been found that this design makes the outermost contact point between the cloth holder and the cloth prone to rapid air leakage due to suction. This leakage is exacerbated by momentary separation caused by vibration during machine movement, leading to insufficient air pressure. Furthermore, the lack of effective sealing measures can cause gaps to form between the cloth and the holder during machine movement, resulting in air leakage and affecting the machine's normal operation and sealing performance. [Utility Model Content]

[0003] To address the problem of suction leakage caused by insufficient sealing at the contact edge between the cleaning machine's cloth holder and the cloth in the prior art, this application provides a sealing structure for the cleaning machine's cloth holder.

[0004] This application is achieved through the following technical solution:

[0005] A sealing structure for a window cleaning machine cloth holder includes a window cleaning machine body, a cloth holder connected to the window cleaning machine body and for covering the cleaning cloth, and a sealing element disposed along the outer edge of the cloth holder. The bottom of the cloth holder is provided with an air inlet, and the sealing element is located between the cleaning cloth and the cloth holder.

[0006] As described above, a sealing structure for a window cleaning machine cloth bracket has a first protrusion along its outer edge and a second protrusion spaced apart from and located inside the first protrusion. A positioning groove for the sealing element is formed between the first protrusion and the second protrusion.

[0007] In the window cleaning machine cloth support sealing structure described above, the first protrusion extending downward from the cloth support has the same height as the second protrusion extending downward from the cloth support.

[0008] As described above, in a window cleaning machine cloth holder sealing structure, the sealing element protrudes from the first and second protruding edges and abuts against the cleaning cloth.

[0009] As described above, a sealing structure for a window cleaning machine cloth bracket includes an extension and an abutment. The extension is located inside the positioning groove, and the abutment is located above the positioning groove. The height H of the extension is the same as the height L of the first and second convex edges.

[0010] The window cleaning machine cloth support sealing structure described above further includes a snap-fit ​​mechanism for connecting the cloth support to the window cleaning machine body. The snap-fit ​​mechanism includes a snap-fit ​​groove and a snap-fit ​​element. The snap-fit ​​groove is used by the snap-fit ​​element to snap and connect the window cleaning machine body and the cloth support. The snap-fit ​​groove is provided on the window cleaning machine body and the snap-fit ​​element is provided on the cloth support; or the snap-fit ​​groove is provided on the cloth support and the snap-fit ​​element is provided on the window cleaning machine body.

[0011] As described above, the sealing structure of the window cleaning machine cloth bracket includes a snap-fit ​​mechanism that further includes connecting blocks on both sides of the snap-fit ​​groove and connecting grooves on both sides of the snap-fit ​​member. The connecting grooves allow the connecting blocks to be inserted to restrict the snap-fit ​​member from disengaging from the snap-fit ​​groove in the horizontal direction.

[0012] In the window cleaning machine cloth support sealing structure described above, the abutting part is arranged in a semi-circular shape.

[0013] As described above, in a window cleaning machine cloth holder sealing structure, the sealing element is interference-fitted with the positioning groove to fix the sealing element on the cloth holder.

[0015] Compared with the prior art, this application has the following advantages:

[0016] This application discloses a sealing structure for a window cleaning machine's cloth holder. By setting a sealing element on the outer edge of the cloth holder, located between the cleaning cloth and the cloth holder, this effectively fills the gap between them, significantly enhancing the sealing performance at the contact edge. During equipment operation and movement, even under vibration or other factors, it prevents air leakage caused by momentary separation, ensuring stable and sufficient internal air pressure. This improves the suction effect and overall efficiency of the machine during cleaning, guaranteeing normal and stable operation. It significantly improves upon the shortcomings of existing technologies where insufficient sealing leads to suction leakage, greatly optimizing and enhancing the performance and reliability of window cleaning machines and other cleaning equipment.

Detailed Implementation Methods

[0026] To make the technical problems solved by this application, the technical solutions, and the beneficial effects clearer, this application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0027] Please see Figures 1 to 8 A sealing structure for a window cleaning machine cloth support includes a window cleaning machine body 1, a cloth support 2 connected to the window cleaning machine body 1 and for covering the cleaning cloth, and a sealing element 4 provided along the outer edge of the cloth support 2. The bottom of the cloth support 2 is provided with an air inlet 21, and the sealing element 4 is located between the cleaning cloth and the cloth support 2.

[0028] This application discloses a sealing structure for a window cleaning machine's cloth holder. By setting a sealing element on the outer edge of the cloth holder, located between the cleaning cloth and the cloth holder, this effectively fills the gap between them, significantly enhancing the sealing performance at the contact edge. During equipment operation and movement, even under vibration or other factors, it prevents air leakage caused by momentary separation, ensuring stable and sufficient internal air pressure. This improves the suction effect and overall efficiency of the machine during cleaning, guaranteeing normal and stable operation. It significantly improves upon the shortcomings of existing technologies where insufficient sealing leads to suction leakage, greatly optimizing and enhancing the performance and reliability of window cleaning machines and other cleaning equipment. The sealing element is made of materials such as silicone or EVA.

[0029] Furthermore, as a preferred embodiment of this solution and not a limitation, the outer edge of the cloth holder 2 is provided with a first protruding edge 22 and a second protruding edge 23 spaced apart from the first protruding edge 22 and located inside the first protruding edge 22, and a positioning groove 24 for the sealing member 4 is formed between the first protruding edge 22 and the second protruding edge 23.

[0030] In this embodiment, a positioning groove 24 is formed between the first protruding edge 22 and the second protruding edge 23 for the sealing element 4 to be installed. The beneficial effect of this structure is that it provides the sealing element 4 with an accurate installation position and stable support, so that the sealing element 4 can be tightly fitted between the cleaning cloth 2 and the wiping cloth bracket 2, effectively enhancing the sealing performance and preventing the sealing element 4 from shifting or falling off due to vibration and other factors during the operation of the window cleaning machine. This avoids air leakage and ensures the stable suction of the window cleaning machine during the cleaning process, improving cleaning efficiency and quality. When the cleaning cloth 2 is fitted onto the wiping cloth bracket 2, the sealing element 4 is located in the positioning groove 24. Due to the restriction of the first protruding edge 22 and the second protruding edge 23, the sealing element 4 can only move vertically within the positioning groove 24 and cannot move horizontally. This ensures that the sealing element 4 is always tightly fitted with the cleaning cloth 2 and the wiping cloth bracket 2, forming a good sealing effect.

[0031] Furthermore, as a preferred embodiment of this solution and not a limitation, the height at which the first convex edge 22 extends downward from the cloth support 2 is the same as the height at which the second convex edge 23 extends downward from the cloth support 2.

[0032] In this embodiment, the seal 4 is ensured to be subjected to balanced force within the positioning groove 24, avoiding local stress concentration caused by height differences, thereby extending the service life of the seal 4 and reducing the risk of seal failure caused by uneven force. Secondly, this design simplifies the manufacturing process, improves manufacturing precision and consistency, and reduces production costs. In terms of working principle, the first convex edge 22 and the second convex edge 23 with the same height provide a stable support platform for the seal 4, enabling it to contact the cleaning cloth evenly and form a continuous and reliable sealing layer, effectively preventing suction leakage.

[0033] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the seal 4 protrudes beyond the first protrusion 22 and the second protrusion 23 and abuts against the cleaning cloth.

[0034] In this embodiment, sufficient contact area and pressure are ensured between the seal 4 and the cleaning cloth to achieve a tighter seal. When the cleaning cloth is fitted onto the cloth holder 2, the protruding seal 4 will contact the cleaning cloth tightly. Due to the elasticity or flexibility of the seal 4, it can adapt to the shape of the cleaning cloth and fill the tiny gaps between them, thereby forming an effective sealing barrier between the cleaning cloth and the cloth holder 2, preventing air leakage from affecting the cleaning effect and suction stability during the operation of the window cleaning machine.

[0035] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the sealing member 4 includes an extension 41 and an abutment 42. The extension 41 is located within the positioning groove 24, and the abutment 42 is located above the positioning groove 24. The height H of the extension 41 is the same as the height L of the first protrusion 22 and the second protrusion 23.

[0036] In this embodiment, the sealing element 4 is stably installed within the positioning groove 24, while the abutment portion 42 effectively and tightly adheres to the cleaning cloth, achieving a good sealing effect. The working principle is that the height of the extension portion 41 is the same as the height of the first protruding edge 22 and the second protruding edge 23, ensuring that the sealing element 4 is adequately supported within the positioning groove 24 and will not loosen or tilt due to height differences, thus guaranteeing the overall stability of the sealing element 4. The abutment portion 42 is located above the positioning groove 24 and can directly contact the cleaning cloth. Because its position is higher than the first protruding edge 22 and the second protruding edge 23, it can better adapt to changes in the thickness of the cleaning cloth, ensuring a tight fit and effectively preventing air leakage.

[0037] Furthermore, as a preferred embodiment of this solution and not a limitation, it also includes a snap-fit ​​mechanism 5 for connecting the wiping cloth bracket 2 and the window cleaning machine body 1. The snap-fit ​​mechanism 5 includes a snap-fit ​​groove 51 and a snap-fit ​​member 52. The snap-fit ​​groove 51 is used by the snap-fit ​​member 52 to snap and connect the window cleaning machine body 1 and the wiping cloth bracket 2. The snap-fit ​​groove 51 is provided on the window cleaning machine body 1 and the snap-fit ​​member 52 is provided on the wiping cloth bracket 2; or the snap-fit ​​groove 51 is provided on the wiping cloth bracket 2 and the snap-fit ​​member 52 is provided on the window cleaning machine body 1.

[0038] This embodiment provides a simple, quick, and reliable connection method, enabling the cloth holder 2 to be securely installed on the window cleaning machine body 1. It also facilitates disassembly and replacement, improving maintenance convenience and service life. The mechanical connection between the cloth holder 2 and the window cleaning machine body 1 is achieved through the cooperation of the snap-fit ​​component 52 and the snap-fit ​​groove 51. After the snap-fit ​​component 52 is inserted into the snap-fit ​​groove 51, its shape and size design allow it to fit tightly within the groove, thus firmly fixing the cloth holder 2 to the window cleaning machine body 1, ensuring that the cloth holder 2 will not loosen or fall off during the operation of the window cleaning machine.

[0039] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the snap-fit ​​mechanism 5 further includes connecting blocks 53 disposed on both sides of the snap-fit ​​groove 51, and connecting grooves 54 disposed on both sides of the snap-fit ​​member 52. The connecting grooves 54 allow the connecting blocks 53 to be inserted to restrict the snap-fit ​​member 52 from disengaging from the snap-fit ​​groove 51 in the horizontal direction.

[0040] In this embodiment, by inserting the connecting block 53 into the connecting groove 54, the horizontal movement of the snap-fit ​​member 52 is restricted, thereby ensuring that the snap-fit ​​member 52 is firmly fixed in the snap-fit ​​groove 51 and will not easily come off due to external force or vibration. This improves the reliability of the window cleaning machine during operation, especially when facing complex working environments and frequent movement, effectively preventing the connection between the cloth bracket 2 and the window cleaning machine body 1 from loosening or falling off, ensuring the normal operation of the equipment and the cleaning effect.

[0041] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the abutment portion 42 is provided in a semi-circular shape.

[0042] In this embodiment, when the semi-circular abutment portion 42 comes into contact with the cleaning cloth, its curved surface can better conform to the surface of the cleaning cloth. Especially when the cleaning cloth has uneven thickness or slight deformation, the semi-circular structure can fill these tiny gaps through its own elastic deformation, ensuring that there is no air leakage between the seal 4 and the cleaning cloth. This design not only improves the sealing performance but also enhances the durability of the seal 4 because the semi-circular structure can distribute pressure more evenly when under stress, reducing damage caused by local overload.

[0043] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the sealing element 4 is interference-fitted with the positioning groove 24 to fix the sealing element 4 on the rag holder 2.

[0044] In this embodiment, by setting the width of the positioning groove to 3 mm or 4 mm and the width of the seal to 3.5 mm-4 mm or 4.5 mm-5 mm, the seal is made of a flexible material and is squeezed into the positioning groove to achieve an interference fit.

[0045] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, it includes a plurality of snap-fit ​​mechanisms 5 spaced apart around the cloth holder 2.

[0046] In this embodiment, the connection between the cloth support 2 and the window cleaning machine body 1 can be uniformly fixed from multiple directions, significantly enhancing the stability and reliability of the overall structure. Multiple locking mechanisms 5 are distributed around the cloth support 2. The locking groove 51 and locking element 52 of each locking mechanism 5 cooperate with each other, working together to ensure that the cloth support 2 is stably supported and fixed in all directions, preventing loosening or detachment due to uneven force at a single point. This multi-point fixing method can effectively disperse external forces, especially vibrations or impacts that may be encountered during the operation of the window cleaning machine, thereby ensuring the stability of the equipment during operation.

[0047] The working principle of this embodiment is as follows:

[0048] This application discloses a sealing structure for a window cleaning machine's cloth holder. By setting a sealing element on the outer edge of the cloth holder, located between the cleaning cloth and the cloth holder, this effectively fills the gap between them, significantly enhancing the sealing performance at the contact edge. During equipment operation and movement, even under vibration or other factors, it prevents air leakage caused by momentary separation, ensuring stable and sufficient internal air pressure. This improves the suction effect and overall efficiency of the machine during cleaning, guaranteeing normal and stable operation. It significantly improves upon the shortcomings of existing technologies where insufficient sealing leads to suction leakage, greatly optimizing and enhancing the performance and reliability of window cleaning machines and other cleaning equipment.
