Description

TECHNICAL FIELD

[0001] The utility model relates to a cleaning robot device technical field, especially a novel cleaning robot. BACKGROUND

[0002] The cleaning robot (intelligent cleaning robot) applied to office places and the like is a device capable of planning a path according to an internal control system and automatically cleaning a ground. The cleaning robot is generally provided with a plurality of sensors connected to the control system on the front and rear and left and right sides of the body, so that the control system can control the working mode of the cleaning robot according to the signals input by the plurality of sensors, thereby ensuring autonomous obstacle avoidance walking and cleaning functions. When the cleaning robot works, the ground is cleaned by the electric rotary broom at the lower front end of the body in a rotary manner, then the front suction disc mechanism at the rear side of the electric rotary broom collects the cleaned garbage by negative pressure (into the garbage can in the garbage bin of the body, and then uniformly poured and treated), and then the rear suction disc mechanism at the lower rear side of the body performs negative pressure cleaning on the ground again (the collected garbage also enters the garbage can in the garbage bin of the body, and then uniformly poured and treated), so that the cleaning effect of the ground is better.

[0003] Although the existing cleaning robot meets the needs of automatic cleaning work to some extent, due to the limitation of structure, there are still some technical problems. Specifically, when cleaning the hardened ground such as cement or tile, the ground can be effectively cleaned by the cooperative work of the electric rotating broom, the front suction cup mechanism and the rear suction cup mechanism, but for the area paved with carpet and the like, in fact, because the surface of the carpet and the like is uneven, the garbage on the ground can only be treated by the negative pressure vacuum generated by the suction cup mechanism, so that the electric rotating broom has no corresponding cleaning effect when cleaning the surface of the carpet, and unnecessary waste of electric energy is caused, and the lower end of the electric rotating broom will also cause certain damage to the carpet when rotating (the bristles of the electric rotating broom head and the surface of the carpet are rubbed, causing the surface of the carpet to be damaged). Therefore, the existing cleaning robot can generally only clean the area of a specific ground, and its application has great application limitations. The existing technology also has a way of fixing the electric rotating broom, the front suction cup mechanism and the rear suction cup mechanism respectively to realize cleaning work in different areas. Specifically, when cleaning the hardened ground such as cement and tile, the height of the low electric rotating broom is adjusted manually by a tool (such as a wrench) to make the electric rotating broom, the front suction cup mechanism and the rear suction cup mechanism cooperate to clean the ground, and when cleaning the non-hardened ground such as carpet, the height of the high electric rotating broom is adjusted manually by a tool to make only the front and rear suction cup mechanisms cooperate to clean the ground, thereby preventing damage to the surface of the carpet. The above adjustment needs to be manually fixed and adjusted by the worker, which is inconvenient for the user and is not conducive to improving the work efficiency. Therefore, it is particularly necessary to provide a cleaning robot capable of automatically adjusting the height of the electric rotating broom. Practical new type
