Description

Technical Field

[0001] The utility model relates to the field of window cleaning machines, in particular to a water outlet end structure of a window cleaning machine which can prevent air backflow. Background Art

[0002] Window cleaning machines have gradually become popular and replaced manual window cleaning. During the window cleaning process, only dry wiping can be performed, and the dry wiping effect is often not ideal, so it is necessary to manually spray some water on the glass, and the window cleaning machine then cooperates with the water to clean the window. Manually spraying water on the glass again and again is not only cumbersome, but also inefficient. Gradually, water tanks are added to the window cleaning machines, but the unreasonable increase of water tanks will not produce ideal water output effects. At the same time, the water output structure of the cleaning machine also needs to be considered. The application number is CN2019205120 after retrieval. 04.6 discloses a window cleaning machine which includes a feeding platform, a cleaning main unit and a discharging platform; a pre-cleaning device is provided between the feeding platform and the feeding port of the cleaning main unit, the pre-cleaning device is a high-pressure water outlet flushing device, and an upper water pipe and a lower water pipe are provided along the feeding port; the upper water pipe and the lower water pipe are connected at both ends to form a rectangle, the upper water pipe and the lower water pipe are respectively connected to a high-pressure water pump, and 5 to 10 nozzles are respectively provided on the upper water pipe and the lower water pipe; the nozzle sprays a high-pressure radial water beam toward the outside of the feeding port, and the vertical direction of the water outlet is 30 to 60 degrees with the plane of the feeding glass. The high-pressure water outlet flushing device also includes an automatic intermittent switch, which can effectively prevent large particles of impurities, large-sized debris or glass of the wrong size from entering the window cleaning machine, reducing the risk of machine damage, but the device still has the following defects in actual use: when the device is in use, air is easily introduced into the structure of the water outlet end, which makes it easy for air to flow back, thereby affecting the spraying of water flow, so it is necessary to design a practical window cleaning machine water outlet end structure.
