TECHNICAL FIELD
[0001] The utility model relates to a cleaning robot device technical field, especially a cleaning robot with cleaning head. 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 sides and the 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 and cleaning functions. When the cleaning robot works, the electric rotary broom (cleaning head) at the lower front end of the body rotates to clean the ground, and then the 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 dumped and treated).
[0003] Although the existing cleaning robot meets the needs of automatic cleaning to some extent, it still has some technical problems due to the structure. Specifically, the two parallelly installed cleaning heads at the lower front end of the body are respectively driven by motors (the upper end of the cleaning head is installed on the lower side of the lifting mechanism of the cleaning robot, and when sweeping the ground, the lifting mechanism controls the cleaning head to move downward to contact the ground for sweeping, and after sweeping, the cleaning head is driven to move upward, facilitating the movement of the robot body to other stations), the structure is relatively complex, and the cost is relatively high. More importantly, the two cleaning heads are distributed horizontally, and there is inevitably some gap between them. Thus, when the device is in a straight-line driving state, the ground between the two cleaning heads may not be effectively cleaned, and the cleaning of the ground may be adversely affected. In addition, the cleaning head of the cleaning robot cannot spray water on the ground during rotation. Thus, when the ground is heavily dusted, there is a possibility that dust will float into the air and affect air quality. In summary, it is particularly necessary to provide a cleaning robot that can achieve better cleaning effect on the ground and reduce dust floating into the air. SUMMARY
