Cleaning device with edge and omnidirectional obstacle detection

Abstract

A cleaning device with edge and omni-directional obstacle detection comprises a machine shell, a negative pressure part is arranged on the inner bottom face of the machine shell, moving units are arranged on the two symmetrical sides of the negative pressure part respectively, sweeping units are arranged on the other two symmetrical sides of the negative pressure part respectively, and the sweeping units are used for cleaning dirt solidified on the surface of a flat object. Edge and omni-directional obstacle detection units are at least arranged at two opposite angles of the machine shell and used for judging whether the current displacement direction, the position of the whole machine or the periphery of the whole machine reaches the edge of the surface of a flat object or whether obstacles exist or not. The edge and omni-directional obstacle detection units, the moving unit and the sweeping units are electrically connected with a main control unit, and a wiping part is arranged on the outer bottom face of the machine shell. The device is stable in movement, not prone to slipping and capable of accurately conducting cleaning operation in a to-be-cleaned area, the cleaning effect on the surface of the flat object is greatly improved, and noise interference to the life of a user during indoor cleaning work can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of cleaning devices, in particular to a cleaning device with edge and omnidirectional obstacle detection. Background technique [0002] Nowadays, there are many high-rise buildings. In order to make the windows of the high-rise buildings clean, it is often necessary to clean the glass on the windows. Working at heights, whether it is simple equipment or advanced equipment, is dangerous and inefficient for glass cleaners. [0003] With the development of science and technology, the emergence of window cleaning robots (also known as automatic window cleaning machines, glass cleaning robots, intelligent window cleaners, intelligent window cleaners, etc.) has greatly reduced the labor intensity and danger of manual glass cleaning.

Problems solved by technology

[0002] Nowadays, there are many high-rise buildings. In order to make the windows of the high-rise buildings clean, it is often necessary to clean the glass on the windows. Working at heights, no matter whether it is simple equipment or advanced equipment, for glass cleaners, working at heights is quite dangerous and inefficient

[0003] With the development of science and technology, the emergence of window cleaning robots (also known as automatic window cleaning machines, glass cleaning robots, intelligent window cleaners, intelligent window cleaners, etc.) has greatly reduced the labor intensity and danger of manual glass cleaning. A kind of household appliance, it can firmly adsorb on the glass with the vacuum pump or fan device at the bottom, and then, with the help of a certain artificial intelligence, it can automatically detect the corner distance of the window and plan the window cleaning path. At the same time, it will Use the strength of its own adsorption on the glass to drive the rag at the bottom of the fuselage to wipe off the dirt on the glass; however, the existing window cleaning robot only has the function of simple detection of no frame or obstacle detection in running state, and the frame detection is not sensitive , if the infrared borderless detection sensor is used, although the problem of insensitive border detection can be solved to a certain extent, the module cost is relatively high, and the walking wheel module of the existing window cleaning robot only has the first driving wheel and the second driving wheel to transfer the transmission belt In this mode, the contact area between the transmission belt and the glass is small. Under the condition of a certain friction coefficient, the friction force between the transmission belt and the glass is small, and the force that can be loaded is small, so that the machine will slip when walking. If sliding friction support is added in the middle This kind of sliding friction support structure will wear the transmission belt for a long time and reduce the service life. In addition, the top models on the market adopt the dry wiping mode in which the machine travels and the cleaning cloth travels, and the sliding friction between the cleaning cloth and the glass is directly used for cleaning. , this cleaning mode requires a lot of friction, the cleaning effect is not good, and the solidified dirt on the glass is difficult to clean
