Window cleaning machine for preventing sewage from flowing backwards

Abstract

The invention provides a window cleaning machine capable of preventing sewage from flowing backwards. The window cleaning machine comprises a window cleaning machine body and an anti-backflow device,wherein the window cleaning machine body comprises a suction nozzle part, a main body part, a power generation device, a power supply device and a storage part; the suction nozzle part is connected with the main body part; wherein the main body part is connected with the storage part, the power generation device is connected with the power supply device, the power generation device and the power supply device are arranged in the main body part, a sewage pipeline is arranged in the main body part, the storage part is provided with a sewage storage cavity, and the anti-backflow device is arranged at the joint of the sewage storage cavity and the sewage pipeline. The structure is simple and reliable, the situation that after a certain amount of sewage is stored in the sewage storage cavity ofthe window cleaning machine, when the window cleaning machine is obliquely used, the sewage in the sewage storage cavity returns according to an original path of a water inlet loop to cause sewage backflow can be avoided, a cleaned area is prevented from being contaminated again by the backflow sewage, and the sewage can also be prevented from dripping onto the ground.

Description

technical field [0001] The invention relates to a window cleaning machine, in particular to a window cleaning machine for preventing backflow of sewage. Background technique [0002] Window cleaning machines are mainly used for cleaning windows and exterior walls of buildings. The traditional window cleaning methods currently on the market are mainly by hanging suspension equipment on the exterior walls of buildings, and window cleaning workers perform high-altitude operations on the suspension equipment. Window cleaning work, this type of high-altitude window cleaning is too bulky and requires a large suspension device to support the operation. Ordinary families cannot afford window cleaning service fees, and high-altitude operations are dangerous and unsafe, and it is inconvenient to replace cleaning water. The efficiency of window cleaning is low. For this kind of problem, other types of window cleaning machines such as household window cleaning machines and household win...

AI Technical Summary

Problems solved by technology

However, after this type of window cleaning machine absorbs a certain amount of sewage, in some scenarios, there will be a use angle where the sewage is easy to return according to the original path of the water inlet circuit, causing the sewage to drip back to the ground or easily make the cleaned area be poured. Irrigate and get dirty again
