[0031] The connecting component comprises a connecting plate 8 fixedly connected to the inside of the hollow bar 2 , and a through hole 9 is formed on the top of the connecting plate 8 .

[0032] The pressure assembly includes a floating block 10 slidably connected to the inside of the hollow bar 2, a connecting rod 11 is fixedly connected to the top of the floating block 10, one end of the connecting rod 11 passes through the top of the hollow bar 2 and is fixedly connected to a connecting bar 12, and a pressure plate 13 is fixedly connected to the bottom of the connecting bar 12. The interiors of the connecting rod 11, the connecting bar 12 and the pressure plate 13 are all hollow, and the connecting bar 12 is L-shaped.

[0033] The conveying assembly comprises a conveying pipe 14 fixedly connected to one side of the dining table body 1 , and a top end of the conveying pipe 14 is fixedly connected to a water inlet hopper 15 .

[0034] The shielding assembly includes two mounting frames 16 fixedly connected to one side of the inner wall of the dining table, the interior of the two mounting frames 16 is fixedly connected with a sliding rod 17, the exterior of the sliding rod 17 is slidably connected with a sliding bar 18, and the side of the sliding bar 18 close to the delivery pipe 14 is fixedly connected with a stopper 19. The two mounting frames 16 are respectively installed on both sides of one end of the delivery pipe 14, and the stopper 19 is circular in shape and its diameter is consistent with the diameter of the delivery pipe 14.

[0035] A plurality of heating tubes 20 are fixedly connected to the interior of the dining table body 1, and a plurality of supporting plates 21 are fixedly connected to the interior of the dining table body 1. The plurality of heating tubes 20 are used to heat the water inside the dining table body 1 to generate steam to heat the food on the dining table.

One end of the water outlet pipe 22 is fixedly connected with the inside of the dining table body 1 and is located below the plurality of heating pipes 20 .

[0037] Working principle: When the heat preservation food vending machine is used, a plurality of heating tubes 20 are started to heat the water inside the food vending machine body 1. When the water is heated to a certain temperature and hot steam is generated, the heat preservation food vending machine will use the rising hot steam to heat the storage box placed at the upper position inside the food vending machine body 1, so as to keep the food inside the storage box warm.

[0038] When the water level inside the heat preservation dining table drops, the water level inside the hollow bar 2 will also drop, causing the floating block 10 to drive the connecting rod 11 and the connecting bar 12 to drop until the bottom of the pressing plate 13 fits with the top of the hollow block 5. At this time, the pressure sensor 6 senses the pressure from the pressing plate 13. After the pressure sensor 6 senses the pressure of the pressing plate 13, it sends a signal and the PLC controller 3 receives it. After the PLC controller 3 receives the signal from the pressure sensor 6, the PLC controller 3 starts the alarm light 4 to alarm, thereby reminding the staff that there is too little water inside the dining table body 1, so that water can be added to the dining table body 1 in time;

[0039] When water needs to be added to the interior of the dining table body 1, the water level inside the dining table body 1 drops, causing the slide bar 18 to drive the block 19 to slide downward along the slide rod 17, so that the block 19 no longer blocks one end of the delivery pipe 14, thereby allowing the delivery pipe 14 to flow, making it convenient for the staff to add water to the interior of the dining table body 1 through the water inlet hopper 15.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
