Specific Embodiment

[0018] Please refer to Figures 1 to 9 , an anti-top side wheel structure of a window cleaning machine, including a window cleaning machine bottom shell 1, a side wheel mechanism 2 provided at the corners of the window cleaning machine bottom shell 1, a cleaning assembly 3 provided at the bottom of the side wheel mechanism 2, and an anti-fall mechanism 4 connected to the window cleaning machine bottom shell 1 and corresponding to the side wheel mechanism 2. The side wheel mechanism 2 is connected to the anti-fall mechanism 4 and is spaced from the window cleaning machine bottom shell 1, so that the side wheel mechanism 2 can float up and down relative to the window cleaning machine bottom shell 1.

[0019] For the anti-top side wheel structure of a window cleaning machine and a window cleaning machine in the present application, when cleaning a framed glass, by providing a side wheel mechanism at the corners of the window cleaning machine bottom shell and equipping a cleaning assembly at the bottom of the side wheel mechanism, the dead corners of the window frame can be cleaned. At the same time, by connecting the anti-fall mechanism, the side wheel mechanism can cooperate with the anti-fall mechanism to float up and down relative to the window cleaning machine bottom shell. When the side wheel mechanism moves to the glass glue slope, due to the interval between the side wheel mechanism and the window cleaning machine bottom shell, the side wheel mechanism can float up and down following the anti-fall mechanism, thus avoiding the situation of the machine being lifted up, ensuring the normal use and cleaning effect of the window cleaning machine, and improving the cleaning ability of the dead corners of the window frame.

[0020] Further, as a preferred implementation manner of this solution rather than a limitation, the side wheel mechanism 2 includes a rotating movable member 21 connected to the window cleaning machine bottom shell 1, an inner side wheel 22 snap-connected to the rotating movable member 21, and an outer side wheel 23 snap-connected to the inner side wheel 22.

[0021] In this embodiment, the side wheel mechanism 2 includes a rotating movable member 21 connected to the window cleaning machine bottom shell 1, an inner side wheel 22 snap-connected to the rotating movable member 21, and an outer side wheel 23 snap-connected to the inner side wheel 22. By connecting the rotating movable member 21 to the window cleaning machine bottom shell 1, the side wheel mechanism 2 can rotate flexibly during the operation of the window cleaning machine, adapt to the unevenness of the window surface, and ensure the cleaning effect. The snap connection between the inner side wheel 22 and the rotating movable member 21, and the snap connection between the outer side wheel 23 and the inner side wheel 22 not only ensure the structural stability of the side wheel mechanism 2, but also facilitate the disassembly and replacement of the side wheels, reduce the maintenance cost, and the side wheels that cooperate with the anti-fall mechanism and are used for cleaning can be replaced, or the side wheels without cleaning effect can be replaced.

[0022] Further, as a preferred implementation manner of this solution rather than a limitation, a first clamping protrusion 221 is provided on the inner side wall of the inner side wheel 22, and a first clamping groove 211 is provided on the rotating movable member 21 for the first clamping protrusion 221 to snap into to connect the inner side wheel 22 and the rotating movable member 21.

[0023] In this embodiment, the firm connection between the inner side wheel 22 and the rotating movable member 21 is achieved through snap connection. This design not only simplifies the assembly process and improves the production efficiency, but also ensures that the inner side wheel 22 will not easily fall off during use, enhancing the reliability of the structure. In terms of the working principle, when the inner side wheel 22 is installed on the rotating movable member 21, the first clamping protrusion 221 will slide into the first clamping groove 211 along the inclined surface 214, and then be restricted in the clamping groove by the first limiting flange 212 and the second limiting flange 213, thus completing the locking. This connection method enables the inner side wheel 22 to rotate together with the rotating movable member 21.

[0024] Further, as a preferred implementation manner of this solution rather than a limitation, a first limiting flange 212 for restricting the first clamping protrusion 221 from disengaging downward from the first clamping groove 211 and a second limiting flange 213 for restricting the first clamping protrusion 221 from disengaging upward from the first clamping groove 211 are provided on the rotating movable member 21, and inclined surfaces 214 for the first clamping protrusion 221 to snap into the first clamping groove 211 are provided on both the first limiting flange 212 and the first clamping protrusion 221.

[0025] In this embodiment, the stability of the connection between the inner side wheel 22 and the rotating movable member 21 is enhanced. The first limiting flange 212 and the second limiting flange 213 cooperate with the inclined surface 214 on the first clamping protrusion 221, enabling the first clamping protrusion 221 to smoothly slide into the first clamping groove 211 and firmly lock after entering, preventing loosening or detachment caused by vibration or external force during use. This structure not only improves the convenience of assembly but also ensures the reliability of the side wheel mechanism 2 in a complex working environment. When the inner side wheel 22 is installed, the first clamping protrusion 221 easily slides into the first clamping groove 211 along the inclined surface 214. Once it enters, the first limiting flange 212 and the second limiting flange 213 immediately come into play, restricting the up-and-down movement of the first clamping protrusion 221, thus completing a firm snap connection.

[0026] Further, as a preferred implementation manner rather than a limitation of this solution, a plurality of outwardly protruding limiting blocks 222 are provided on the inner side wheel 22, and a clamping groove 231 for the limiting blocks 222 to snap into is provided on the inner side wall of the outer side wheel 23. The clamping groove 231 allows the limiting blocks 222 to move up and down so that the outer side wheel 23 can float up and down relative to the inner side wheel 22.

[0027] In this embodiment, through this snap connection method, not only is a firm connection between the inner side wheel 22 and the outer side wheel 23 achieved, but also the outer side wheel 23 is allowed to float up and down relative to the inner side wheel 22. The main beneficial effect brought by this design is to enhance the adaptability of the side wheel mechanism 2 to the uneven surface of the window frame and effectively address the problem of the machine being lifted due to the glass glue slope. When the outer side wheel 23 encounters a glass glue slope, the limiting blocks 222 can move up and down in the clamping groove 231, enabling the outer side wheel 23 to adaptively lift or lower, thereby preventing the entire window cleaning machine from being lifted and ensuring the continuity and stability of the cleaning process. The cooperation between the limiting blocks 222 and the clamping groove 231 allows the outer side wheel 23 to have a certain degree of floating freedom while maintaining the connection with the inner side wheel 22. This floating mechanism ensures that the outer side wheel 23 can closely adhere to the window surface, providing uniform cleaning pressure both in flat areas and on slopes, thus improving the cleaning effect.

[0028] Further, as a preferred implementation manner rather than a limitation of this solution, the depth H of the clamping groove 231 corresponds to the distance S between the outer side wheel 23 and the bottom shell 1 of the window cleaning machine.

[0029] In this embodiment, the depth H of the clamping groove 231 determines the floating range of the outer edge wheel 23 in the vertical direction, while the spacing distance S between the outer edge wheel 23 and the bottom shell 1 of the window cleaning machine directly affects the adaptability of the edge wheel mechanism to the uneven surface at the window frame during the cleaning process. When the two correspond, it means that when the outer edge wheel 23 encounters glass glue or other protrusions, it can make full use of its floating range for buffering, while avoiding affecting the overall stability of the window cleaning machine due to excessive floating. Among them, the distances of S and H can be controlled between 2MM and 3MM.

[0030] Further, as a preferred implementation manner of this solution rather than a limitation, the anti-fall mechanism 4 includes an anti-fall rod 41 and an elastic member 42 provided on the anti-fall rod 41 and the rotary movable member 21, and the elastic member 42 drives the anti-fall rod 41 to push against the outer edge wheel 23.

[0031] In this embodiment, the anti-fall rod 41 always maintains a state of pushing against the outer edge wheel 23 under the action of the elastic member 42, ensuring that the outer edge wheel 23 can closely fit the window surface and provide continuous and stable cleaning pressure. Secondly, the elastic characteristics of the elastic member 42 enable the anti-fall rod 41 to make adaptive adjustments according to the floating requirements of the outer edge wheel 23, neither overly restricting the floating freedom of the outer edge wheel 23 nor providing additional support when necessary, thereby enhancing the adaptability of the edge wheel mechanism 2 to the uneven window surface. The elastic member 42 continuously pushes the anti-fall rod 41 towards the outer edge wheel 23 through its own elastic force, so that one end of the anti-fall rod 41 remains in contact with the outer edge wheel 23. When the outer edge wheel 23 needs to float due to encountering a glass glue slope or other obstacles, the elastic member 42 can be compressed or extended accordingly to adapt to the up and down movement of the outer edge wheel 23, while ensuring that the anti-fall rod 41 always provides necessary support and protection. When it is applicable to clean the outer edge wheel, the anti-fall function of the anti-fall rod fails, so it is only applicable to framed windows.

[0032] Further, as a preferred implementation manner of this solution rather than a limitation, a limiting platform 232 for restricting the anti-fall rod 41 from extending downward beyond the bottom of the outer edge wheel 23 is provided at the bottom of the outer edge wheel 23.

[0033] In this embodiment, when the elastic member 42 pushes the anti-fall rod 41 to move towards the outer edge wheel 23, one end of the anti-fall rod 41 will contact the limiting platform 232 and be restricted above this platform. The anti-fall rod 41 will not extend downward beyond the bottom of the outer edge wheel 23, enabling the outer edge wheel to achieve the up-and-down floating function by means of the anti-fall rod and the elastic member, making the cleaning mechanism closely fit the window surface during cleaning, and when encountering a glass glue slope, it can achieve a floating effect and avoid the phenomenon of the machine being jammed. During the cleaning process, when the anti-fall rod pushes against the outer edge wheel, it will not trigger the fall induction of the anti-fall rod. When encountering a glass glue slope, the outer edge wheel can also drive the anti-fall rod to float upward under the action of an external force, and the floating distance is equivalent to the height of the glass glue.

[0034] Further, as a preferred implementation manner rather than a limitation of this solution, the cleaning assembly 3 includes a cleaning cloth 31 detachably connected to the bottom of the limiting platform 232.

[0035] In this embodiment, the detachably connected cleaning cloth 31 enables the user to easily replace and clean the cleaning cloth without disassembling the entire edge wheel mechanism 2, greatly simplifying the maintenance process. When the cleaning cloth 31 is worn or dirty, the user only needs to remove it from the bottom of the limiting platform 232 and replace it with a new cleaning cloth, which not only saves time and effort but also ensures that the window cleaning machine always maintains a good cleaning effect. Adopting snap connection, adhesive connection or Velcro connection can ensure that the cleaning cloth 31 will not easily fall off during use.

[0036] A window cleaning machine includes the anti-jamming edge wheel structure described above.

[0037] The working principle of this embodiment is as follows: For the anti-jamming edge wheel structure and window cleaning machine of this application, when cleaning a framed glass, by setting an edge wheel mechanism at the corners of the bottom shell of the window cleaning machine and equipping a cleaning assembly at the bottom of the edge wheel mechanism, the dead corners of the window frame can be cleaned. At the same time, connecting an anti-fall mechanism enables the edge wheel mechanism to cooperate with the anti-fall mechanism to achieve relative up-and-down floating with respect to the bottom shell of the window cleaning machine. When the edge wheel mechanism moves to the glass glue slope, due to the gap between the edge wheel mechanism and the bottom shell of the window cleaning machine, the edge wheel mechanism can float up and down following the anti-fall mechanism, thus avoiding the situation of the machine being lifted, ensuring the normal use and cleaning effect of the window cleaning machine, and improving the cleaning ability of the dead corners of the window frame.

[0038] The above are the implementation manners provided in combination with specific contents, and it is not considered that the specific implementation of this application is only limited to these descriptions. Any structure similar to the method of this application, or several technical deductions or replacements made under the premise of the concept of this application, should be regarded as the protection scope of this application.
