Abstract
Description
[Technical Field]
[0001] This application belongs to the field of window cleaning machine technology, specifically relating to a cleaning wheel structure and a window cleaning machine. [Background Technology]
[0002] Existing square window cleaning machines generally use a four-corner drop bar design, but this structure makes it difficult to effectively clean the corners and edges of framed windows. The presence of the frame restricts the range of motion of the window cleaning machine, preventing it from getting close enough to the corners for thorough cleaning, thus leaving cleaning blind spots. These blind spots not only affect the cleaning effect but can also lead to the long-term accumulation of dust and stains, thereby affecting the overall aesthetics of the building and the hygiene of the indoor environment. [Utility Model Content]
[0003] To address the problem that existing window cleaning machines with four-corner drop bar structures cannot effectively clean the blind corners of window frames, this application provides a cleaning wheel structure and a window cleaning machine.
[0004] This application is achieved through the following technical solution:
[0005] A cleaning wheel structure, characterized in that it includes a window cleaning machine base shell, a wheel mechanism disposed at the corner of the window cleaning machine base shell, a cleaning component disposed at the bottom of the wheel mechanism, and an anti-fall mechanism connected to the window cleaning machine base shell and disposed corresponding to the wheel mechanism, wherein the anti-fall mechanism drives the wheel mechanism to push the cleaning component to adhere to the cleaning surface.
[0006] As described above, the cleaning wheel structure includes a rotating movable component connected to the bottom shell of the window cleaning machine, an inner wheel snapped into the rotating movable component, and an outer wheel snapped into the inner wheel.
[0007] In the cleaning wheel structure described above, the inner sidewall of the inner wheel is provided with a first locking protrusion, and the rotating movable component is provided with a first locking groove for the first locking protrusion to engage and connect the inner wheel to the rotating movable component.
[0008] As described above, in a cleaning wheel structure, the rotating movable component is provided with a first limiting flange for restricting the first card protrusion from disengaging downward from the first card slot, and a second limiting flange for restricting the first card protrusion from disengaging upward from the first card slot. Both the first limiting flange and the first card protrusion are provided with inclined surfaces for the first card protrusion to engage with the first card slot.
[0009] As described above, in a cleaning wheel structure, the inner wheel is provided with a plurality of outwardly protruding limiting blocks, and the inner sidewall of the outer wheel is provided with a retaining groove for the limiting blocks to be engaged.
[0010] As described above, in a cleaning wheel structure, the anti-fall mechanism includes an anti-fall bar and an elastic member disposed on the anti-fall bar and the rotating movable member, wherein the elastic member drives the anti-fall bar to push against the outer wheel.
[0011] As described above, in one type of cleaning wheel structure, the bottom of the outer wheel is provided with a limiting platform for restricting the anti-fall bar from extending downwards from the bottom of the outer wheel.
[0012] As described above, in a cleaning wheel structure, the cleaning component includes a cleaning cloth detachably connected to the bottom of the limiting platform.
[0013] A window cleaning machine includes a cleaning wheel structure as described above.
[0014] Compared with the prior art, this application has the following advantages:

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 9 A cleaning wheel structure, characterized in that it includes a window cleaning machine base shell 1, a wheel mechanism 2 disposed at the corner of the window cleaning machine base shell 1, a cleaning component 3 disposed at the bottom of the wheel mechanism 2, and an anti-fall mechanism 4 connected to the window cleaning machine base shell 1 and disposed corresponding to the wheel mechanism 2, wherein the anti-fall mechanism 4 drives the wheel mechanism 2 to push the cleaning component 3 to adhere to the cleaning surface.
[0028] This application discloses a cleaning wheel structure and a window cleaning machine. When cleaning framed glass, a wheel mechanism is installed at the corner of the bottom shell of the window cleaning machine, and a cleaning component is equipped at the bottom of the wheel mechanism. Since the wheel mechanism is located at the four corners of the cleaning machine, when the right angle of the window cleaning machine corresponds to the right angle of the window frame, the dead corners of the window frame can be cleaned. At the same time, an anti-fall mechanism is connected. The anti-fall mechanism can always drive the cleaning component to adhere to the glass surface and have a certain pressure, 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.
[0029] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the side wheel mechanism 2 includes a rotating movable part 21 connected to the bottom shell 1 of the window cleaning machine, an inner side wheel 22 snapped to the rotating movable part 21, and an outer side wheel 23 snapped to the inner side wheel 22.
[0030] In this embodiment, the side wheel mechanism 2 includes a rotating movable component 21 connected to the bottom shell 1 of the window cleaning machine, an inner side wheel 22 snapped together with the rotating movable component 21, and an outer side wheel 23 snapped together with the inner side wheel 22. The connection between the rotating movable component 21 and the bottom shell 1 of the window cleaning machine allows the side wheel mechanism 2 to rotate flexibly during the operation of the window cleaning machine, adapting to uneven window surfaces and ensuring cleaning effectiveness. The snap-fit connection between the inner side wheel 22 and the rotating movable component 21, and the snap-fit connection between the outer side wheel 23 and the inner side wheel 22, not only ensures the structural stability of the side wheel mechanism 2 but also facilitates the disassembly and replacement of the side wheels, reducing maintenance costs. Side wheels that cooperate with the anti-fall mechanism and are used for cleaning can be replaced, as can side wheels that do not have a cleaning effect.
[0031] Furthermore, as a preferred embodiment of this solution and not a limitation, the inner sidewall of the inner wheel 22 is provided with a first locking protrusion 221, and the rotating movable member 21 is provided with a first locking groove 211 for the first locking protrusion 221 to engage and connect the inner wheel 22 to the rotating movable member 21.
[0032] In this embodiment, a snap-fit connection is used to securely connect the inner wheel 22 to the rotating movable part 21. This design not only simplifies the assembly process and improves production efficiency, but also ensures that the inner wheel 22 will not easily fall off during use, enhancing the reliability of the structure. In terms of working principle, when the inner wheel 22 is installed onto the rotating movable part 21, the first locking protrusion 221 slides along the inclined surface 214 into the first locking groove 211, and is subsequently restrained within the groove by the first limiting flange 212 and the second limiting flange 213, thus completing the locking process. This connection method allows the inner wheel 22 to rotate together with the rotating movable part 21.
[0033] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the rotating movable component 21 is provided with a first limiting flange 212 for restricting the first locking protrusion 221 from disengaging downward from the first locking groove 211, and a second limiting flange 213 for restricting the first locking protrusion 221 from disengaging upward from the first locking groove 211. Both the first limiting flange 212 and the first locking protrusion 221 are provided with inclined surfaces 214 for the first locking protrusion 221 to engage with the first locking groove 211.
[0034] In this embodiment, the stability of the connection between the inner side wheel 22 and the rotating movable part 21 is enhanced. The first limiting flange 212 and the second limiting flange 213 cooperate with the inclined surface 214 on the first locking protrusion 221, allowing the first locking protrusion 221 to slide smoothly into the first locking groove 211 and lock firmly after entering, preventing loosening or falling off due to 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 complex working environments. When the inner side wheel 22 is installed, the first locking protrusion 221 easily slides into the first locking groove 211 along the inclined surface 214. Once in place, the first limiting flange 212 and the second limiting flange 213 immediately take effect, restricting the up and down movement of the first locking protrusion 221, thereby completing a secure snap-fit connection.
[0035] Furthermore, as a preferred embodiment of this solution and not a limitation, the inner wheel 22 is provided with a plurality of outwardly protruding limiting blocks 222, and the inner sidewall of the outer wheel 23 is provided with a retaining groove 231 for the limiting blocks 222 to be engaged.
[0036] In this embodiment, this snap-fit connection method not only achieves a stable connection between the inner wheel 22 and the outer wheel 23, but also prevents the inner wheel from falling off when the outer wheel is pulled out by applying external force for replacement.
[0037] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the anti-fall mechanism 4 includes an anti-fall bar 41 and an elastic member 42 disposed on the anti-fall bar 41 and the rotating movable member 21, wherein the elastic member 42 drives the anti-fall bar 41 to push against the outer wheel 23.
[0038] In this embodiment, the anti-fall bar 41, under the action of the elastic element 42, always maintains a pushing state against the outer edge wheel 23, 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 element 42 allow the anti-fall bar 41 to adaptively adjust according to the floating requirements of the outer edge wheel 23, neither excessively restricting the floating freedom of the outer edge wheel 23 nor lacking additional support when necessary, thereby enhancing the adaptability of the edge wheel mechanism 2 to uneven window surfaces. The elastic element 42, through its own elasticity, continuously pushes the anti-fall bar 41 towards the outer edge wheel 23, keeping one end of the anti-fall bar 41 in contact with the outer edge wheel 23. When the outer edge wheel 23 needs to float due to encountering a glass sealant slope or other obstacles, the elastic element 42 can compress or extend accordingly to accommodate the up-and-down movement of the outer edge wheel 23, while ensuring that the anti-fall bar 41 always provides necessary support and protection. When used for cleaning the outer edge wheel, the anti-fall function of the anti-fall bar is ineffective; therefore, it is only suitable for framed windows.
[0039] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the bottom of the outer wheel 23 is provided with a limiting platform 232 for limiting the anti-fall bar 41 from extending downwards out of the bottom of the outer wheel 23.
[0040] In this embodiment, when the elastic element 42 pushes the anti-fall bar 41 towards the outer wheel 23, one end of the anti-fall bar 41 contacts the limiting platform 232 and is restricted above the platform. The anti-fall bar 41 will not extend downwards beyond the bottom of the outer wheel 23, allowing the outer wheel to float up and down using the anti-fall bar and the elastic element. This ensures that the cleaning mechanism fits tightly against the window surface during cleaning, and it can float when encountering a glass sealant slope, preventing the machine from hitting the wall. During the cleaning process, when the anti-fall bar pushes against the outer wheel, it will not trigger the anti-fall bar's drop sensor. When encountering a glass sealant slope, the outer wheel can also cause the anti-fall bar to float upwards under external force, with the floating distance being approximately equal to the height of the glass sealant.
[0041] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the cleaning component 3 includes a cleaning cloth 31 that is detachably connected to the bottom of the limiting platform 232.
[0042] In this embodiment, the detachable cleaning cloth 31 allows users to easily replace and wash it without disassembling the entire side wheel mechanism 2, greatly simplifying the maintenance process. When the cleaning cloth 31 is worn or dirty, the user simply removes it from the bottom of the limiting platform 232 and replaces it with a new cleaning cloth. This not only saves time and effort but also ensures that the window cleaning machine always maintains a good cleaning effect. The use of snap-on, adhesive, or Velcro connections ensures that the cleaning cloth 31 will not easily fall off during use.
[0043] A window cleaning machine, including the aforementioned cleaning wheel structure.
[0044] The working principle of this embodiment is as follows:
[0045] This application discloses a cleaning wheel structure and a window cleaning machine. When cleaning framed glass, a wheel mechanism is installed at the corner of the bottom shell of the window cleaning machine, and a cleaning component is equipped at the bottom of the wheel mechanism. Since the wheel mechanism is located at the four corners of the cleaning machine, when the right angle of the window cleaning machine corresponds to the right angle of the window frame, the dead corners of the window frame can be cleaned. At the same time, an anti-fall mechanism is connected. The anti-fall mechanism can always drive the cleaning component to adhere to the glass surface and have a certain pressure, 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.
