[0001] This application relates to the field of cleaning equipment technology, and more particularly to a window cleaning machine. Background Technology

[0002] A window cleaning machine is a device used for cleaning windows. It can move on glass and clean the glass surface. Window cleaning machines can replace manual labor for cleaning windows on high-rise buildings and outdoors.

[0003] The air duct of a window cleaning machine is used for airflow to achieve exhaust. Existing window cleaning machines consist of an outer casing and an air duct housing, which are typically assembled together. After a period of use, the outer casing and / or air duct housing may deform to some extent, leading to gaps at the junction of the outer casing and air duct housing, thus reducing the sealing performance of the air duct. Utility Model Content

[0004] The purpose of this application is to overcome the deficiencies of the prior art and provide a window cleaning machine to solve the problems in the prior art.

[0005] To address the aforementioned issues, this application provides a window cleaning machine, comprising a housing and a fan, wherein the fan is disposed inside the housing; the fan includes an air outlet, and the housing is provided with an exhaust outlet; the air outlet and the exhaust outlet are connected by a connecting pipe for discharging the airflow generated by the fan.

[0006] In one possible implementation, the air outlet and the exhaust outlet are connected by an integrally formed connecting pipe to improve the airtightness between the air outlet and the exhaust outlet.

[0007] In one possible implementation, the fan includes a plurality of air outlets, and the housing is provided with a plurality of exhaust outlets, wherein the air outlets and the exhaust outlets correspond to each other, and the air outlets are connected to the corresponding exhaust outlets.

[0008] In one possible implementation, the air outlet and the corresponding exhaust outlet are located on opposite sides of the fan.

[0015] The beneficial effects of this application include:

[0016] The window cleaning machine proposed in this application includes a casing and a fan. The fan is located inside the casing, and the air outlet of the fan is connected to the exhaust section of the casing via a connecting pipe.

[0030] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0031] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0032] The existing air duct designs for window cleaning machines include the following three cases:

[0033] 1. When a window cleaning machine uses a top cover for air outlet, the duct housing fits into the top cover of the machine's outer casing to form an air duct. Since the top cover is often a curved structure, the area where the duct housing and the top cover meet also needs to be curved. The fit between curved surfaces inherently carries the risk of insufficient sealing; therefore, when the duct housing and / or the top cover deform, the airtightness of the duct is more easily affected.

[0034] 2. When the window cleaning machine uses a bottom cover for air outlet, the duct housing, the pressure cover, and the lower shell of the window cleaning machine work together to form the duct. During product assembly, gaps may exist at the transition surfaces between the above components due to dimensional tolerances, which may affect the airtightness of the duct.

[0035] 3. When the air duct is designed independently, the air duct housing includes a first housing portion and a second housing portion, which cooperate with each other to form the air duct. During product assembly, the first housing portion and / or the second housing portion needs to be connected to the outer shell for fixation. When the air duct housing and / or the outer shell deform, the air duct's sealing performance will be affected.

[0036] While gaps, areas where gaps may exist, and areas where gaps may occur can be sealed by applying glue or sealant, this will increase the manufacturing cost.

[0037] Furthermore, given a fixed size for the window cleaning machine, the size of the air duct is significantly constrained. When the duct length is insufficient, the airflow passing through it cannot be effectively buffered, resulting in considerable noise during exhaust.

[0038] The window cleaning machine proposed in this application can effectively solve the above-mentioned technical problems.

[0039] Example

[0040] See Figure 1 and Figure 2 In this embodiment, a window cleaning machine is proposed, including a housing 100 and a fan 200, with the fan 200 disposed inside the housing 100. The fan 200 includes an air outlet 210, and an exhaust outlet 110 is provided on the housing 100. The air outlet 210 and the exhaust outlet 110 are connected by a connecting pipe 300 for discharging the airflow generated by the fan 200.

[0041] To facilitate observation of the internal structure of the window cleaning machine, the top cover of the housing 100 is not shown in the attached drawings. It should be noted that in other embodiments, the exhaust vent 110 may be located on the top cover of the housing 100 or on other parts of the housing 100 as needed.

[0042] When the window cleaning machine is running, the fan 200 is in operation. The fan 200 generates negative pressure so that the window cleaning machine can adhere to the glass. When the fan 200 is working, air in the suction cup of the window cleaning machine is drawn into the fan 200 through the air inlet. The drawn-in air flows from the air outlet 210 into the connecting pipe 300, and is finally discharged outside the window cleaning machine through the exhaust outlet 110.

[0043] The air outlet 210 and the exhaust outlet 110 are connected by an integrally formed connecting pipe 300, which is used to improve the airtightness of the air outlet 210 to the exhaust outlet 110.

[0044] The fan 200 includes several air outlets 210 and several exhaust outlets 110 are provided on the outer casing 100. The air outlets 210 and the exhaust outlets 110 correspond to each other. The air outlets 210 are connected to the corresponding exhaust outlets 110 through corresponding connecting pipes 300.

[0045] In this embodiment, the air outlet 210 and the exhaust outlet 110 can correspond one-to-one, which facilitates the installation, maintenance and replacement of the connecting pipe 300, and can also effectively improve the exhaust efficiency. In some embodiments, one air outlet 210 can correspond to multiple exhaust outlets 110, or multiple air outlets 210 can correspond to one exhaust outlet 110.

[0046] like Figure 1 As shown, in this embodiment, the air outlet 210 and the corresponding exhaust outlet 110 are both located on the same side of the fan 200.

[0047] like Figure 3 As shown, in other embodiments, the air outlet 210 and the corresponding exhaust outlet 110 are located on opposite sides of the fan 200, which can extend the length of the air duct within a limited space to improve the buffering effect on the airflow and reduce the noise generated when the airflow is discharged.

[0048] The connecting pipe 300 uses a flexible hose. The flexible hose can be bent and deformed, and is easy to install, clean and replace.

[0049] Reference Figure 4 The window cleaning machine is used to bend the connecting pipe 300 so that the connecting pipe 300 adapts to the space inside the housing 100, thereby achieving effective and full utilization of the space inside the housing 100.

[0050] like Figure 5 As shown, in one embodiment, the flexible hose includes an S-shaped structure. (As illustrated...) Figure 6 As shown, in another embodiment, the flexible hose includes a U-shaped structure. In other embodiments, the flexible hose may also include both an S-shaped structure and a U-shaped structure.

[0051] Reference Figure 1 and Figure 2 The connecting pipe 300 includes a first end 310 and a second end 320 located at both ends. The first end 310 is sealed and connected to the corresponding air outlet 210, and the second end 320 is sealed and connected to the corresponding exhaust outlet 110.

[0052] In this embodiment, the air outlet 210 includes a first connecting post protruding from the fan 200, and the exhaust section 110 includes a second connecting post protruding from the outer casing 100. The first connecting post is connected to the first end 310, and the second connecting post is connected to the second end 320.

[0053] The first end 310 is sleeved or inserted into the air outlet 210 with an interference fit, thereby achieving a sealed connection between the first end 310 and the air outlet 210. The second end 320 is sleeved or inserted into the exhaust 110 with an interference fit, thereby achieving a sealed connection between the second end 320 and the exhaust 110.

[0054] Taking the connection between the first end 310 and the air outlet 210 as an example. Figure 7 The diagram shows a connection between the first end 310 and the air outlet 210, wherein the first end 310 is sleeved on the air outlet 210 and is interference-fitted.

[0055] like Figure 8 and Figure 9 As shown, an annular buckle 211 is provided on the outer wall of the air outlet 210, and an annular groove 311 is provided inside the first end 310. When the air outlet 210 and the first end 310 are assembled, the buckle 211 and the groove 311 engage, thereby improving the reliability of the connection between the air outlet 210 and the first end 310.

[0056] In this embodiment, the air outlet 210 is provided with air outlet holes inside, the sum of the cross-sectional areas of each air outlet hole is S1, and the cross-sectional area of ​​the air inlet of the fan 200 is S2, wherein S1≥S2. In this way, the air outlet efficiency of the fan 200 can be improved, enabling the fan 200 to generate a stable negative pressure, so as to ensure that the window cleaning machine can be stably adsorbed on the surface of the glass.
