Referring to fig. 1 to 3, a cleaning robot 1000 includes a robot body 100, a rolling brush 200, and an airflow generating device 300, wherein the rolling brush 200 is used for cleaning a floor (such as sucking dust, mopping the floor, washing the floor, etc.), and the airflow generating device 300 is used for drying the rolling brush 200.

The robot body 100 not only serves as a bearing structure for other components (such as a main control module, a walking module, etc.) of the cleaning robot 1000, but also serves as an appearance member of the cleaning robot 1000, and the robot body 100 has various shapes, which may be cylindrical, D-shaped, or square, and is not limited herein.

The machine body 100 is provided with a cleaning chamber 100a having a lower end opened, the cleaning chamber 100a being for accommodating the drum brush 200, the cleaning chamber 100a being communicable with a dust box of the cleaning robot 1000, the cleaning chamber 100a also being communicable with a sewage tank 116 of the cleaning robot 1000, so that dust, debris, sewage, etc. raised when the drum brush 200 is operated can be recovered.

The rolling brush 200 may be formed of a rotating shaft and bristles, and at this time, the rolling brush 200 may perform a dust removing or floor washing operation on the floor, or the rolling brush 200 may be formed of a rotating shaft and a mop, and at this time, the rolling brush 200 may perform a mopping operation on the floor.

The roller brush 200 is rotatably installed in the cleaning cavity 100a and is in clearance fit with the cavity wall of the cleaning cavity 100a, two ends of the roller brush 200 in the axial direction are rotatably connected to the machine body 100, and the roller brush 200 is rotatably connected to the machine body 100 in various ways, for example, the roller brush 200 is rotatably connected to the machine body 100 through a rotating shaft and a bearing, and the roller brush 200 is rotatably connected to the machine body 100 through a rotating shaft and a shaft sleeve.

The roller brush 200 is partially protruded from the opening of the cleaning chamber 100a when it is installed in the cleaning chamber 100a so that the peripheral wall of the roller brush 200 can contact with the surface to be cleaned, for example, the protruding volume of the roller brush 200 from the opening of the cleaning chamber 100a is one fourth of its own volume, and the protruding volume of the roller brush 200 from the opening of the cleaning chamber 100a is one fifth of its own volume, which is not particularly limited herein.

The airflow generating device 300 is a device capable of driving air to flow, the airflow generating device 300 may be a fan, an air pump, or the like, the airflow generating device 300 is mainly used for driving the air around the roller brush 200 to flow, that is, the airflow generating device 300 may have an air inlet end communicated with the cleaning cavity 100a, the airflow generating device 300 may have an air outlet end communicated with the cleaning cavity 100a, and the airflow generating device 300 may have an air inlet end and an air outlet end both communicated with the cleaning cavity 100 a.

Preferably, the air outlet end of the airflow generating device 300 is disposed toward the rolling brush 200, the air is accelerated by the airflow generating device 300, and after the air flowing fast blows toward the rolling brush 200, the evaporation of the water on the rolling brush 200 can be decelerated, thereby facilitating the improvement of the air drying speed of the rolling brush 200.

The airflow generating device 300 is installed on the machine body 100, the airflow generating device 300 can be installed inside the machine body 100, and the airflow generating device 300 can also be installed outside the machine body 100, preferably, the airflow generating device 300 is installed inside the machine body 100, so that the appearance of the cleaning robot 1000 can be ensured to be flat, and the airflow generating device 300 can be prevented from being exposed to the outside and being damaged.

When the cleaning robot 1000 cleans the ground, the control module of the cleaning robot 1000 controls the operation of the walking module and the rolling brush 200, the walking module drives the whole cleaning robot 1000 to move on the ground, when the cleaning robot 1000 is a dust collection robot, the rolling brush 200 lifts dirt such as dust, debris and the like on the ground, and when the cleaning robot 1000 is a floor mopping robot, the rolling brush 200 effectively mops the dirt on the ground.

After the rolling brush 200 of the cleaning robot 1000 finishes the cleaning work, the airflow generating device 300 drives the air to flow, so that the air with a certain flow rate passes through the rolling brush 200, thereby accelerating the flow rate of the air around the rolling brush 200, facilitating the rolling brush 200 to keep dry, and avoiding the problems of mildewing and smelliness of the rolling brush 200.

It should be noted that, most of the roller brush 200 is accommodated in the cleaning chamber 100a, and if the air flow generating device 300 blows air into the cleaning chamber 100a from outside the cleaning chamber 100a, air must enter from the opening of the cleaning chamber 100a and must be exhausted from the opening of the cleaning chamber 100a, so that the amount of air entering and exiting per unit time in the cleaning chamber 100a is relatively small, and the air drying speed of the roller brush 200 is affected.

In view of the above problems, the air outlet end of the airflow generating device 300 is communicated with the cleaning cavity 100a, the airflow generating device 300 drives the outside air to enter the cleaning cavity 100a, and finally the outside air is blown out through the opening of the cleaning cavity 100a, so that the opening of the cleaning cavity 100a can be ensured to be only air-out, the air output in unit time is ensured, and the air drying speed of the rolling brush 200 is further ensured.

6. The cleaning robot of claim 5, wherein a surface of the machine body adjacent to the cleaning chamber is recessed with a fitting groove, and the apron covers a notch of the fitting groove to form the ventilation channel in cooperation with the body structure.

7. The cleaning robot as claimed in claim 6, wherein the surface of the enclosing plate facing the assembling groove is convexly provided with a reinforcing rib plate, and the bottom of the assembling groove is correspondingly provided with a positioning groove for inserting and matching with the reinforcing rib plate.

8. The cleaning robot as claimed in claim 6, wherein the surface of the body structure is further recessed with a recess communicating with the fitting groove, and the body structure further includes a cover plate for covering the recess to enclose with the recess a transfer passage communicating with the ventilation passage and the airflow generating device.

9. The cleaning robot as claimed in claim 8, wherein the side surface of the body structure is recessed with an insertion groove located around the groove, and the cover plate is correspondingly provided with an insertion plate engaged with the insertion groove.

10. A cleaning robot as claimed in any one of claims 5 to 9, wherein the body structure includes a housing and a water tank fitted to the housing and defining the cleaning chamber therewith, the ventilation passage and the air outlet being provided in the water tank;

the air flow generating device is arranged on the upper surface of the shell, the lower surface of the water tank is provided with an accommodating concave part and an air inlet positioned in the accommodating concave part, and the air inlet is communicated with the ventilation channel;

when the water tank is assembled to the shell from top to bottom, the air flow generating device extends into the accommodating concave part, and the air outlet end of the air flow generating device is communicated with the air inlet in a butt joint mode.

11. The cleaning robot as claimed in claim 10, further comprising a docking head fixed to the housing, wherein one end of the docking head is in communication with the air outlet end of the airflow generating device, and the other end of the docking head is adapted to be inserted into the air inlet.
