Inside the first groove, there are provided first protrusions 631 the number of which is the same as the number of through holes through which the first protrusions 631 pass, and a spring catch 62 provided at the top end of the first protrusions 631 to restrain the base plate 612 within the first groove.

The spring clip 62 abuts against a device on the cleaning robot for pushing the dust pushing assembly 6, and when the cleaning robot is switched to the dust pushing mode, the device pushes the dust pushing assembly 6 to move towards the direction close to the ground, so that the cleaning cloth on the dust pushing 65 of the dust pushing assembly 6 contacts the ground to clean the ground. And the influence of the ground undulation on the cleaning robot is reduced by the elasticity of the spring clip 62.

The dust deriving block 64 is arranged on one side, close to the ground, of the dust pushing clamping plate 63, and a second bulge corresponding to the second groove is arranged on one side, far away from the ground, of the dust deriving block 64, and the second bulge is nested in the second groove. The dust pushing fixture block 66 is fixed on one side of the dust pushing clamping block and the dust deriving block 64, which is vertical to the bottom surface, two ends of the dust pushing fixture block 66 are respectively fixed on the dust deriving block 64 and the dust pushing clamping plate 63, and the dust pushing fixture block 66 is used for fixing the dust pushing guide block 64.

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

The cleaning robot of the present invention will be further explained by the working flow of the cleaning robot.

The control panel receives a cleaning instruction input by a user, and sends the cleaning instruction to the chassis control module 22 through the serial port. The chassis control module 22 turns on the dust collection assembly 3 after receiving the cleaning instruction, and sends the cleaning area to the navigation assembly 4 through a serial port. The navigation module 4 finishes route planning, generates traveling data of the driving wheel 51, and sends route planning information and the traveling 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 assembly 4 in real time through the serial port, so that the navigation assembly 4 updates the walking route in real time according to the obstacle information. After the chassis control module 22 judges that the cleaning area is completely covered, the cleaning is confirmed to be completed, the chassis control module 22 closes the dust collection assembly 3, the cleaning completion feedback is sent to the control panel through the serial port, and after the control panel receives the cleaning completion feedback, the user is informed through the touch screen 211.

Has the advantages that: the utility model discloses cleaning machines people with function of making an uproar falls the wind channel of making an uproar and encircles the fan setting, has expanded the length that falls the wind channel of making an uproar to noise reduction effect is further improved through the soundproof cotton in falling the wind channel of making an uproar, thereby effectively reduces the noise, and the noise reduction improves its experience of living to guest's influence.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
