[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the "one embodiment" or "embodiment" referred to herein refers to specific features, structures or characteristics that may be included in at least one implementation method of the present invention. The "in one embodiment" appearing in different places in this specification does not all refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments. The present invention provides the following embodiments.

[0031] The utility model proposes a self-propelled cleaning robot, such as Figure 1 , Figure 2 and Figure 3 As shown, it includes a chassis 1, a dust suction pump and a driving assembly. The dust suction pump and the driving assembly are both installed inside the chassis 1. The bottom of the chassis 1 is rotatably connected to two driving wheels 3, and the two driving wheels 3 are symmetrically arranged at both ends of the driving assembly. A universal wheel 2 is arranged at the bottom of the chassis 1 for driving the robot to move. The universal wheel 2 can adjust the direction of the robot's movement.

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, a battery compartment 17 is provided at the center of the bottom of the chassis 1, which can supply power to the entire robot. A cleaning motor 9 is fixedly installed at the bottom of the chassis 1 on one side of the battery compartment 17, and a cleaning disc 10 is fixedly connected to the outside of the output shaft of the cleaning motor 9. A brush 11 is fixedly connected to the outward side of the cleaning disc 10, which can clean the garbage to the rear side when the robot moves forward. A cleaning roller 4 is rotatably connected to the bottom of the chassis 1, and the cleaning roller 4 is connected to the driving component through a gear transmission, which drives the cleaning roller 4 to rotate when the robot moves forward. The rollers 4 rotate at the same time to transport the garbage online. Two limiting plates 13 are symmetrically fixedly connected to the top of the chassis 1. A dust box 14 is clamped between the two limiting plates 13. A limit fixing plate is provided for the dust box 14. A movable door is provided on the top of the dust box 14, and a rubber pad is provided on the contact surface between the movable door and the dust box 14. A docking pipe 19 is fixedly connected to the bottom of the inner cavity of the dust box 14. The docking pipe 19 is docked with the output end of the dust suction pump, and the dust suction pump is located above the cleaning roller 4. In the process of the cleaning roller 4 sweeping and transporting upward, the dust is sucked. The pump will further transport the garbage online and make it enter the interior of the dust box 14. Both sides of the dust box 14 are provided with card slots adapted to the limit plate 13. A cavity is provided on the outer wall of the dust box 14. The interior of the cavity is fixedly connected to the limit rod 20. The outside of the limit rod 20 is slidably connected to the contact plate 22.

The spring is sleeved on the outside of the limit rod 20, and one end of the spring is fixedly connected to one side of the contact plate 22, and the other end of the spring is fixed to the dust box. The inner wall of the two limit plates 14 is fixedly connected, one end of the contact plate 22 is arc-shaped, and the opposite surfaces of the two limit plates 13 are provided with arc grooves adapted to the contact plate 22. The contact plate 22 can move forward and backward through the stretching and contraction action of the spring. When the dust box 14 is embedded between the two limit plates 13, one end of the contact plate 22 docks with the arc groove, thereby fixing the dust box 14. When disassembling, the dust box 14 is pushed forward with force, so that the contact plate 22 can be contracted by the spring, and then the dust box 14 can be removed.

[0033] like Figure 1 , Figure 2 , Figure 3 and Figure 6As shown, a water tank 7 is fixedly installed on the outside of the chassis 1 on one side of the cleaning roller 4, and a water inlet pipe is fixedly installed on the outside of the water tank 7 to provide cleaning water for the robot during cleaning, and an electric telescopic rod 5 is fixedly installed on the bottom of the water tank 7, and a cleaning plate 6 is fixedly connected to the telescopic end of the electric telescopic rod 5.

During the cleaning process, the electric telescopic rod 5 can drive the cleaning plate 6 to move downward so that the wiping pad is in contact with the ground. Since the connecting water pipe 8 is in contact with the wiping pad, the inside of the wiping pad contains moisture, thereby achieving the effect of mopping the floor. The outside of the cleaning plate 6 is fixedly connected to the inside of the water tank 7 through the connecting water pipe 8, and an atomizer is fixedly installed on the top of the chassis 1 directly above the water tank 7. Box 15, the top of the atomizing box 15 is snapped with a top cover 23 to prevent dust from entering the atomizing box 15, the interior of the top cover 23 is fixedly connected with a discharge pipe, a micro pump 24 is fixedly installed at the bottom of the inner cavity of the atomizing box 15, the input end of the micro pump 24 is fixedly connected with the interior of the water tank 7 through an extraction pipe 18, a partition is fixedly connected to the inner wall of the atomizing box 15, and an atomizer 25 is fixedly installed inside the partition to atomize the liquid inside the atomizing box 15, the input end of the atomizer 25 is fixedly connected with the output end of the micro pump 24 through a connecting pipe, and the liquid is transported to the atomizer 25 for atomization, a servo motor 26 is fixedly installed on the top of the partition, and a fan blade 27 is fixedly installed on the output shaft of the servo motor 26 to blow out the atomized liquid.

[0034] like Figure 1 and Figure 2 A sterilization lamp 16 is fixedly installed at the bottom of the chassis 1. The input end of the sterilization lamp 16 is electrically connected to the output end of the battery compartment 17, so that the ground can be irradiated and sterilized during the cleaning process. Sensors 12 are fixedly installed on both sides of the bottom of the chassis 1, and the sensor 12 is a set of transmitters and receivers that emit infrared rays downward. It can sense the height of the robot's position through reflected infrared rays to prevent the robot from falling into the pit.

[0035] What needs to be explained in the above scheme is that the driving components, vacuum pump, dual-mode collision-free sensing system inside the robot, self-rescue and anti-stuck function, automatic charging, autonomous navigation path planning, wide-angle camera (120°), routing WIFI and other functions are all technologies of existing cleaning robots, so there is no need to elaborate on them.

[0036] The working principle of the utility model is as follows: the two driving wheels 3 are driven forward by the driving assembly, the universal wheel 2 can adjust the direction of the robot's advancement, and the cleaning robot can move along a set route. During the movement, the garbage can be cleaned through the cleaning disc 10 and the cleaning roller 4, and transported to the inside of the dust box 14 through the cleaning pump. At the same time, the wiping pad can clean the cleaned floor. In addition, when necessary, the circuit elements inside the atomizing box 15 can be started to spray the atomized liquid, which can not only reduce the dryness of the room, but also reduce dust, thereby improving the functionality of the robot.
