As people's demands for the quality of their living environment increase, the need for natural lighting in homes is receiving more and more attention, leading to an increase in the number of windows in rooms. This has provided room for the development of window cleaning machines.

[0003] Most window cleaning machines use negative pressure fans to create a pressure difference for adsorption. The vibration generated by the negative pressure fans can increase the noise of the window cleaning machine and may damage parts, affecting its service life. There is an urgent need for a solution to these problems. Summary of the Invention

[0033] The following will further describe the present application in detail in conjunction with the accompanying Figures 1-3 drawings and specific embodiments, but it does not limit the present application.

[0034] Embodiment

[0035] The following will describe Embodiment 1 in conjunction with the accompanying Figure 1 drawings.

[0036] An air duct assembly for a window cleaning machine includes a negative pressure air hood 1, a conveying pipeline 2, and an output air hood 3 that are connected in sequence. The negative pressure air hood 1 is used to cover the negative pressure component, and the output air hood 3 is used to cover the moving component. There is no need to set an extra air outlet. The conveying pipeline 2 and the air hood are connected by a soft rubber pipeline 4.

[0037] In practical applications, the soft rubber pipeline 4 is made of materials such as rubber, silicone rubber, TPU, TPE, or soft PVC with the same function. The soft rubber pipeline 4 can block the vibration generated by the negative pressure component from being transmitted without affecting the normal operation of the window cleaning machine, achieving the effect of shock absorption, thereby reducing noise and the possibility of component damage caused by vibration.

[0038] The air duct assembly for the window cleaning machine in this embodiment is overall in a mountain shape, which can reduce the required space while ensuring the normal and smooth operation of the negative pressure function.

[0039] Specifically, the conveying pipeline 2 is overall in a丄 shape. The conveying pipeline 2 includes a first conveying pipe 21 and a second conveying pipe 22 that are connected. There are two second conveying pipes 22, which are respectively located on both sides of the first conveying pipe 21. The first conveying pipe 21 is connected to the negative pressure air hood 1, and the soft rubber pipeline 4 is connected to the second conveying pipe 22.

[0040] Specifically, there are two output air hoods 3 corresponding to the second conveying pipe 22. The output air hood 3 includes a first output hood 32 and a second output hood 33 connected by a connecting component 31. The first output hood 32 includes a hood body 321 and a connecting body 322 that are connected. The connecting body 322 is connected to the second conveying pipe 22. The two ends of the soft rubber pipeline 4 are respectively sleeved on part of the connecting body 322 and the second conveying pipe 22. The connecting body 322 and the second conveying pipe 22 are set as pipe body structures with the same diameter. The setting of the connecting body 322 ensures that the soft rubber pipeline 4 can connect the conveying pipeline 2 and the output air hood 3, reducing the possibility of air leakage. The shape of the hood body 321 is the same as that of the second output hood 33. The position and number of the output air hood 3 correspond to the position and number of the moving components required by the actual window cleaning machine and are set according to actual needs.

[0041] Specifically, a mounting bracket 5 is connected to the side of the first output cover 32 facing the negative pressure shroud 1. The mounting bracket 5 is used to install external driving components. Part of the mounting bracket 5 is connected to the output shroud 3. The setting of the mounting bracket 5 ensures the normal operation of the moving components.

[0042] Specifically, the connecting component 31 includes a first connecting pipe 311, a second connecting pipe 312, and a fixing screw 313 located inside the first connecting pipe 311 and the second connecting pipe 312. The correspondingly provided first connecting pipe 311 and second connecting pipe 312 are respectively connected to the first output cover 32 and the second output cover 33. The above structure makes it easy to disassemble and install the first output cover 32 and the second output cover 33.

[0043] Implementation

[0044] like Figure 2-3 The window cleaning machine shown includes a base plate 100 and a housing 200 covered on the base plate 100. A negative pressure component 300 and a moving component 400 are installed on the base plate 100. The negative pressure component 300 and the moving component 400 are covered with an air duct component 500 for the window cleaning machine as described in Embodiment 1.

[0045] It is understandable that the negative pressure component and the moving component are conventional components of window cleaning machines in the existing technology, including water spraying components, control components and motion components, etc. In order to achieve the basic cleaning function of window cleaning machines, they will not be described in detail here.

[0046] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0047] Based on the disclosure and teachings of the foregoing specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this application is not limited to the specific embodiments described above, and any obvious improvements, substitutions, or modifications made by those skilled in the art based on this application are within the scope of protection of this application.
