[0025] During specific implementation, the inner rear ends of the two connecting plates 3 are both provided with connecting support blocks 4 , and the dust suction pipes are fixedly connected to the connecting support blocks 4 .

[0026] During specific implementation, the dust collection duct includes a middle section duct 5, a lower section duct 7, a connecting joint 8, a connecting seat 9 and an upper section duct 14. The middle section duct 5 is fixedly connected to the connecting support block 4. The bottom end of the middle section duct 5 is connected to the lower section duct 7 through the connecting joint 8. The lower section duct 7 extends out of the bottom of the Mecanum wheel 10. The outer wall of the lower section duct 7 is provided with a connecting seat 9. The lower section duct 7 is connected to the top of the Mecanum wheel 10 through the connecting seat 9. The upper section duct 14 is located above the middle section duct 5, and the stretching assembly 6 is arranged between the two to connect the two.

[0027] In a specific implementation, the stretching assembly 6 includes a servo motor 601, an adjusting rod 602, a connecting pipe 603 and a pull rod 604. The connecting pipe 603 is connected between the middle pipe 5 and the upper pipe 14. The servo motor 601 is arranged on both sides of the connecting pipe 603. The output end of the servo motor 601 is connected to the adjusting rod 602. One end of the adjusting rod 602 is rotatably connected to one end of the pull rod 604.

The touch screen 104 is connected to the control main board through internal wiring of the lunch box 1. A voice module, a Bluetooth module, an ultrasonic module, etc. are also embedded inside the lunch box 1. Instructions to the food delivery robot can be issued through voice interaction, and work tasks of the food delivery robot can also be issued through buttons designed on the touch screen.

[0033] In specific implementation, the inner cavity of the dining box 1 is provided with a transverse plate 101, and the front side of the dining box 1 is provided with a box cover 103, which is designed to be transparent, so that the user can directly observe the transportation of the dishes.

[0034] In specific implementation, slots are opened on both sides of the inner cavity of the dining box 1, and the two ends of the transverse plate 101 are tightly inserted into the slots. Flexible gaskets are provided on the surface of the slots to reduce the vibration effect generated by the food delivery robot during movement.

[0035] In specific implementation, a plurality of circular notches are equidistantly provided on the upper surface of the transverse plate 101, and dining bowls 102 are placed in the circular notches. The design of the transverse plate 101 leaves a stable placement for subsequent bowls of dishes.

[0036] The present invention provides a wheeled meal delivery and cleaning robot, and designs a multifunctional structure including a dust suction pipe, a Mecanum wheel, an auxiliary small wheel and other components, so that the robot has both meal delivery and cleaning functions. The dust suction pipe of the device cooperates with the Mecanum wheel, the auxiliary small wheel and the like, and controls the Mecanum wheel to stand up or lay flat through a stretching component to achieve different functional conversions in the wheeled mode. When the Mecanum wheel stands up, the robot is guaranteed to move freely in a small space to deliver meals efficiently. When the Mecanum wheel is laid flat, the auxiliary small wheel cooperates with a circular brush and a vacuum cleaner to perform cleaning work. Furthermore, the thermostat, the horizontal plate and other designs inside the meal box can effectively ensure the freshness of the dishes and stably place the meal bowls. In addition, the touch screen on the meal box cooperates with the embedded voice module, the Bluetooth module, the ultrasonic module and the like to facilitate the user to issue instructions. Compared with the traditional meal delivery and cleaning robots with single functions, this multifunctional integrated robot reduces the equipment cost and space occupation, can adapt to a variety of scenarios, and greatly improves the practicality and work efficiency of the robot in the field of catering services.
