[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0030] Figure 1 The figure shows a schematic structural diagram of a cleaning device applied to a window cleaning machine provided by an exemplary embodiment of the present invention. Figure 2An axial side schematic diagram of a cleaning head of a cleaning device applied to a window cleaning machine provided by an exemplary embodiment of the utility model is shown. The cleaning device applied to the window cleaning machine is installed on a gondola 1 of the window cleaning machine. The cleaning device applied to the window cleaning machine includes: a transverse guide rail 2 installed on the side wall of the gondola 1, a vertical guide rail 3 slidably connected to the transverse guide rail 2, a hinge block 4 slidably connected to the vertical guide rail 3, and an articulated arm 5, the first end of which is hinged to the hinge block 4 and the second end of which is hinged to a cleaning head 6; wherein the cleaning head 6 includes at least a cleaning roller 61 for cleaning glass, and a roller 62 for guiding the rolling of the cleaning head 6, and the cleaning roller 61 is driven by a rotating motor built into the cleaning head 6.

[0031] In an embodiment of the present application, the cleaning device used in the window cleaning machine is installed on the window cleaning machine's hanging boat 1 close to the side of the glass to be cleaned. The horizontal guide rail 2 and the vertical guide rail 3 provide moving tracks in two directions, and the articulated arm 5 provides a more flexible multi-degree-of-freedom operating space. The articulated arm 5 has at least two joints.

[0032] In the embodiment of the present application, the transverse guide rail 2 , the vertical guide rail 3 , and the articulated arm 5 are all equipped with built-in servo motors to provide power.

[0033] Specifically, Figure 2 The figure shows an axial side view of a cleaning head of a cleaning device applied to a window cleaning machine provided by an exemplary embodiment of the present invention. Figure 3 A schematic front view of a cleaning head for a window cleaning machine according to an exemplary embodiment of the present invention is shown. The cleaning head 6 further includes a scraper 63 located above a cleaning roller 61 for scraping the glass surface cleaned by the cleaning roller 61 dry. The cleaning head 6 further includes a wastewater recovery port 64 located between the cleaning roller 61 and the scraper 63 for sucking wastewater collected by the scraper 63 into a wastewater tank within the cleaning head 6, where suction is provided by a built-in vacuum pump. The cleaning head 6 further includes a detergent nozzle 65 located below the cleaning roller 61 for spraying detergent onto the glass surface. The detergent nozzle 65 is connected to a liquid storage tank within the cleaning head 6 and sprayed by a jet pump. The cleaning head 6 further includes an air blower 66 located above the scraper 63 for evaporating moisture from the cleaned glass surface. The air blower 66 is provided by a fan within the cleaning head 6. In one example, the scraper 63 is made of rubber.

[0034] It is worth mentioning that Figure 4 A side view schematic diagram of a cleaning head of a cleaning device applied to a window cleaning machine provided by an exemplary embodiment of the present invention is shown. A pressure sensor 622 is installed on one side of the roller shaft 621 of the roller 62 for detecting a position signal when the roller 62 is pressed against the glass.

[0035] In the embodiment of the present application, the installation direction of the pressure sensor 622 is perpendicular to the direction of the glass wiper. It can be understood that the installed roller 621 can move within a small range along the direction perpendicular to the glass wiper to provide pressure to the pressure sensor 622 after contacting the glass surface.

[0036] Further, see Figure 1 The cleaning device used in the window cleaning machine also includes a control operation box 7 installed on the hanging boat 1. The control operation box 7 is electrically connected to the horizontal guide rail 2, the vertical guide rail 3, the articulated arm 5, and the cleaning head 6, and is used to provide power to each component and coordinate the work of each component.

[0037] It can be understood that the control operation box 7 also has relevant control buttons for controlling the operation of the cleaning device applied to the window cleaning machine, and a programmable touch screen.

[0038] Next, the working principle of the cleaning device applied to the window cleaning machine involved in the embodiment of the present invention is described.

[0039] The operator activates the cleaning device of the window cleaning machine through the control box in the gondola. After it moves to the wiping starting point via the horizontal and vertical guide rails, the pressure sensor in the roller confirms that the cleaning device is in contact with the glass surface to be cleaned. The articulated arm cooperates with the vertical guide rail to wipe up and down, and then moves horizontally via the horizontal guide rail to continue wiping up and down. This cycle realizes the automatic cleaning of the window glass.

[0040] When the cleaning device used in the window cleaning machine is in the wiping state, the detergent nozzle first sprays the detergent onto the glass surface, and then the cleaning roller is used to clean the glass surface. Then, the scraper is used to scrape the glass surface cleaned by the cleaning roller dry, and then the sewage collected on the scraper is sucked into the sewage tank inside the cleaning machine head through the sewage recovery port, and finally the moisture on the cleaned glass surface is evaporated through the air outlet.

[0041] In summary, by providing a transverse guide rail mounted on the side wall of the gondola, a vertical guide rail slidably connected to the transverse guide rail, a hinge block slidably connected to the vertical guide rail, and an articulated arm hinged to the hinge block at a first end and hinged to a cleaning head at a second end; wherein the cleaning head includes at least a cleaning roller for cleaning the glass and a roller for guiding the cleaning head in rotation. In this case, an automatic cleaning device capable of being mounted on the gondola is provided, whose movement can be controlled by a program to achieve an automatic cleaning function. By introducing this device, not only can cleaning efficiency be greatly improved and labor costs reduced, but also the safety of the operation can be significantly improved and the occurrence of accidents can be reduced.

[0042] In the embodiments disclosed in this utility model, the terms "installed," "connected," "connected," and "fixed" should be understood in a broad sense. For example, "connected" can mean a fixed connection, a detachable connection, or an integral connection; "connected" can mean a direct connection or an indirect connection through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the embodiments disclosed in this utility model based on specific circumstances.

[0043] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
