[0057] It should be noted that the length of the hot water pipe 122 can be set longer, leaving a portion of the hot water pipe 122 extended before and after the rotating mechanism 16 rotates, so that the various components will not collide during operation.

[0058] like Figure 3 and Figure 5 As shown, the propulsion mechanism 15 includes: an installation box 151, a first stepper motor 152, a gear 153, a rack 154 and a connecting rod 156, the installation box 151 is connected to the rear wall of the casing 1; the first stepper motor 152 is installed on the installation box 151; the gear 153 is connected to the output end of the first stepper motor 152, and the gear 153 is located in the installation box 151; the rack 154 is meshed and connected above the gear 153; the lower end of the connecting rod 156 is connected to the rack 154, and the upper end of the connecting rod 156 extends upward through the through hole 1511 set at the top of the installation box 151 so as to connect the rotating mechanism 16.

[0059] Preferably, the rack 154 is slidably matched with the installation box 151. Specifically, a slide rail 155 is transversely installed in the installation box 151, and the connecting rod 156 is slidably connected to the slide rail 155, so that the rotation mechanism 16 moves more smoothly.

[0060] In the embodiment of the present application, the rotating mechanism 16 includes: a second stepper motor 162, a rotating shaft 163 and a connecting plate 165, the second stepper motor 162 is connected to the connecting rod 156 through a protective cover 161; the rotating shaft 163 is connected to the second stepper motor 162; the connecting plate 165 is connected between the rotating shaft 163 and the accommodating cylinder 171.

[0066] It should be noted that the food heated in the present application is pre-prepared food such as fast food. An inner box for placing the pre-prepared food is provided inside the lunch box 8. A protective film 81 is wrapped around the outside of the lunch box 8. There is a gap between the inner box and the lunch box 8 for accommodating hot water. The needle 174 pierces the protective film 81 and extends into the gap to inject water.

[0067] Working principle: heating can only be carried out after scanning the code and paying. After paying, the door 4 is opened, the lunch box 8 is placed on the lunch box positioning frame 9, and the door 4 is closed. The heating time is selected through the operation panel 2, and then the control system 5 controls the first stepper motor 152 to drive the gear 153 to rotate, so that the rack 154 drives the rotating mechanism 16 and the piercing assembly 17 to move forward, and the piercing assembly 17 is above the lunch box 8. Then the second stepper motor 162 is started, driving the rotating shaft 163 to rotate downward 90 degrees, so the connecting plate 165 drives the piercing assembly 17 to rotate downward 90 degrees. During the rotation process, the piercing needle 174 pierces the protective film 81 and enters the gap, and then the control The system 5 controls the pump body 123 to start, and at the same time controls the water heating device 12. The hot water in the water heating device 12 enters the receiving tube 171 through the hot water pipe 122, and finally is injected into the lunch box 8 from the water injection port 1742. After the hot water injection is completed, the second stepper motor 162 drives the rotating shaft 163 to rotate 90 degrees upward, and drives the piercing assembly 17 to rotate 90 degrees upward. Then, the first stepper motor 152 drives the gear 153 to rotate, and the rack 154 drives the rotating mechanism 16 and the piercing assembly 17 to move backward and reset. At the same time, the microwave heating device 13 is started to heat the lunch box 8. After heating, the door 4 is opened and the lunch box 8 can be taken out from the access port 6. By heating the extracted water first and then heating the lunch box 8 by microwave, this double heating can improve the heating efficiency.

[0068] In the embodiment of the present application, the water heating device 12 performs instant heating. For example, after scanning the code to pay, it starts to absorb water from the water bucket 10, and then heats it through the water heating device 12. After the lunch box 8 is placed in, hot water is directly injected, which makes the heating efficiency higher.

[0069] The above description is only the preferred embodiment of the present application and is not intended to limit the present application.
