In this embodiment, the dust pusher 65 is fixed on the side of the dust pusher block 64 away from the dust pusher board 63, and the dust pusher block 64 is provided with a through hole through which the dust pusher 65 and the dust pusher block 64 are fixed together .

The cleaning robot of the present invention will be further described below through the work flow of the cleaning robot.

The control board receives the cleaning instruction input by the user, and sends the cleaning instruction to the chassis control module 22 through the serial port. After receiving the cleaning instruction, the chassis control module 22 turns on the vacuuming assembly 3 and sends the cleaning area to the navigation assembly 4 through the serial port. The navigation component 4 completes the route planning, generates the driving wheel 51 travel data, and sends the route planning information and travel data to the chassis control module 22 through the serial port. The chassis control module 22 controls the driving wheel 51 to walk according to the walking data, and feeds back the obstacle information received by the sensor to the navigation component 4 in real time through the serial port, so that the navigation component 4 updates the walking route in real time according to the obstacle information. After judging that the cleaning area is fully covered, the chassis control module 22 confirms that the cleaning is completed. The chassis control module 22 closes the vacuuming assembly 3, and sends the cleaning completion feedback to the control panel through the serial port. After the control panel receives the cleaning completion feedback, it informs the user through the touch screen 211.

Beneficial effects: The cleaning robot with noise reduction function of the present invention sets the noise reduction air duct around the fan, expands the length of the noise reduction air duct, and further improves the noise reduction effect through the sound insulation cotton in the noise reduction air duct, thereby effectively reducing noise. , reduce the impact of noise on guests and improve their stay experience.

The above-mentioned embodiments are only the preferred embodiments of the present invention, and the scope of protection of the present invention cannot be limited by this. Any insubstantial changes and replacements made by those skilled in the art on the basis of the present invention belong to the scope of the present invention. The scope of protection of the present utility model.
