The cleaning vehicle chassis 2 is used to provide a base and support, and to protect and support internal components. Tires 4 are arranged at the edges of the upper and lower ends of the cleaning vehicle chassis 2. Four groups of tires 4 are arranged. The cleaning vehicle body 1, the cleaning vehicle chassis 2 and the four groups of tires 4 constitute a cleaning vehicle structure. The edge of the bottom end surface of the cleaning vehicle body 1 is meshed with the edge of the top end surface of the cleaning vehicle chassis 2. The cleaning vehicle body 1 and the cleaning vehicle chassis 2 are meshed with the tires 4 to form a cleaning vehicle.

[0023] The sewage suction ports 3 are arranged on both sides of the surface of the cleaning vehicle chassis 2. The two groups of sewage suction ports 3 are dust suction ports on the cleaning vehicle chassis 2, providing openings for the cleaning vehicle to absorb dust and dirt on the ground to keep the ground clean. The opening and closing components 7 are respectively arranged on one side of the opposite surface of the two groups of sewage suction ports 3. The opening and closing components 7 can control the opening and closing state of the sewage suction ports 3 in real time according to the feedback of the sensor, so that the cleaning vehicle can clean up the dirt in time, thereby improving the cleaning efficiency. When enough dust or debris is detected, the opening and closing components 7 will quickly open the sewage suction ports 3 to ensure that the dirt is effectively cleaned. The assembly 7 includes a waterproof box 701, a motor 702, a fixing pin 703, a flip cover plate 704 and a rubber ring 705. The waterproof box 701 is arranged at one side of the sewage suction port 3. The motor 702 is installed inside the waterproof box 701. The sealing design and waterproof material are used to protect the motor 702 from water and dust to ensure the normal operation of the motor 702. The inner cavity of the waterproof box 701 is provided with a motor 702. The motor 702 is installed in the waterproof box 701 to control the opening and closing state of the flip cover plate 704 to realize the automatic opening and closing function of the sewage suction port 3. The upper and lower ends of the right side of the sewage suction port 3 are provided with fixing pins 703, which are provided at the upper and lower ends of the right side of the sewage suction port 3 and are used to fix the flip cover plate 704 to ensure its stable opening and closing state, so that the flip cover plate 704 remains stable during operation without loosening or misalignment, and a flip cover plate 704 is provided on one side of the sewage suction port 3, and the flip cover plate 704 is equal in shape and size to the sewage suction port 3, and the two ends of one side of the flip cover plate 704 are engaged in the inner cavity of the two groups of fixing pins 703, and one end of the flip cover plate 704 passes through one group of fixing pins 703 and the output end of the motor 702 The flip cover plate 704 is connected to the sewage suction port 3 in shape and size, one end of which is connected to the output end of the motor 702 by penetrating one of the sets of fixing pins 703, and the other end is fixed by another set of fixing pins 703, which is used to control the opening and closing state of the sewage suction port 3. A rubber ring 705 is provided at the edge of the flip cover plate 704. The rubber ring 705 is provided at the edge of the flip cover plate 704. The elasticity and sealing performance of the rubber ring 705 are used to seal the sewage suction port 3, ensuring that the sewage suction port 3 can be effectively sealed during operation, avoiding secondary scattering of dirt, and keeping it clean;

[0024] The two groups of sewage suction ports 3 are both provided with photoelectric sensors 8 on one side facing outwards. The two groups of opening and closing components 7 can respectively trigger the motor 702 to rotate the flip cover plate 704 through the two groups of photoelectric sensors 8, thereby opening the two groups of sewage suction ports 3. Once the dirt on the ground is sucked in, the photoelectric sensor 8 triggers the motor 702 through the controller to restore the flip cover plate 704 to its original position, thereby closing the sewage suction port 3 to prevent the dirt from falling out again, thereby effectively avoiding secondary pollution and keeping clean. A handle 6 is provided on the right side of the knob switch 5. The handle 6 provides the user with a grip 6 to facilitate the user to move the cleaning vehicle. Buckle covers 9 are provided on both sides of the cleaning vehicle body 1, and card slots 10 are provided on both sides of the cleaning vehicle chassis 2. The two groups of buckle covers 9 are respectively engaged with the two groups of card slots 10. The two groups of buckle covers 9 can provide reliable fixation between the cleaning vehicle body 1 and the cleaning vehicle chassis 2 through the structure engaged with the card slots 10, ensuring that the connection between the cleaning vehicle chassis 2 and the cleaning vehicle body 1 is firm and reliable, and is not easy to shake or fall off.

[0025] In summary, if Figures 1 to 5 As shown, the automatic opening and closing device of the sewage suction port, the cleaning vehicle body 1 and the cleaning vehicle chassis 2 are meshed with the tire 4 to form a cleaning vehicle structure, the knob switch 5 controls the start and stop of the cleaning vehicle by sending a signal to the control system, and the grip 6 provides a gripping handle 6 for the user to move the cleaning vehicle conveniently, and the buckle covers 9 on both sides of the cleaning vehicle body 1 are respectively inserted into the card slots 10 on both sides of the cleaning vehicle chassis 2, which will generate a certain resistance. When the buckle covers 9 are fully inserted into the card slots 10 and buckled, a firm connection is formed, thereby merging the two;

[0026] When the floor needs to be cleaned, the photoelectric sensor 8 will detect the dirt on the floor in real time. Once the sensor detects dust or debris, the photoelectric sensor 8 will send a signal to the control system, and the control system will start the motor 702 in the opening and closing component 7. The motor 702 drives the flip cover plate 704 to flip, and the two sets of fixing pins 703 support and limit the two ends of the flip cover plate 704, so that the flip cover plate 704 rotates in the inner cavity of the fixing pins 703, and then the flip cover plate 704 closed on the surface of the sewage suction port 3 is rotated to open, thereby maintaining The sewage suction port 3 is opened and closed so that the dirt can be effectively cleaned. After the dirt is sucked in, the photoelectric sensor 8 will detect the ground condition again. Once cleaning is detected, the control system will drive the motor 702 to rotate the flip plate 704 to close it quickly, thereby closing the sewage suction port 3. The rubber ring 705 ensures that the sewage suction port 3 can be effectively sealed when the flip plate 704 is closed through its own elasticity and sealing performance. The waterproof box 701 is used to protect the motor 702 from water and dust through its sealing design and waterproof material, thereby ensuring the normal operation of the motor 702.
