[0017] (III) Beneficial effects
[0018] Compared with the prior art, the present utility model provides a self-heating device for a food vending machine, which has the following
[0019] Beneficial effects:
[0020] 1. The self-heating device of this food vending machine incorporates a sealing mechanism. By activating a lifting mechanism, the sealing plate is raised or lowered, moving to the outside of the heating window to shield it and prevent rapid heat diffusion during heating. After the food is heated, a vacuum pump draws the hot air out of the heating window through a cooling pipe, rapidly cooling the interior and preventing burns to staff when removing food. This sealing device effectively seals the front of the heating window, guiding and preventing rapid heat diffusion, thus improving heat utilization and solving the problem of heat loss during heating in traditional equipment.
[0021] 2. The self-heating device of this food vending machine is equipped with a lifting device. The servo motor drives the transmission roller to rotate, so that the transmission roller, driven roller and synchronous belt module are driven by friction. The synchronous belt module drives the lifting platform to move up and down along the machine body, so that the lifting platform pushes the sealing plate up and down. In this way, by activating the lifting device, the sealing plate is pushed up and down, so that the sealing plate can move to the outside of the heating window, so as to block and cover the heating window, thereby preventing the rapid diffusion of hot air during the heating process.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Please see Figure 1 and Figure 2 The self-heating device of the food vending machine includes a sales cabinet 1, an operation screen 2, an intelligent shelf 3, a retrieval window 4, a heating window 5, a heating plate 6, a sealing device 7, and a product exchange door 8. The operation screen 2 is installed at the front end of the sales cabinet 1. The intelligent shelf 3 is fixed to the interior of the sales cabinet 1. The retrieval window 4 is located at the front end of the sales cabinet 1. The heating window 5 is located at the right end of the retrieval window 4. The operation screen 2 is installed on the top of the heating window 5. The heating plate 6 is installed inside the heating window 5. The sealing device 7 is connected to the front end of the sales cabinet 1 and is slidably connected to the front end of the heating plate 6.
[0030] Please see Figure 3 Figures and Figure 4 The self-heating device of the food vending machine, the sealing device 7 includes a housing 71, an electric control switch 72, a sealing plate 73, an air pump 74, a cooling pipe 75, and a lifting device 76. The electric control switch 72 is installed at the front end of the housing 71 and is electrically connected to the front end of the lifting device 76. The sealing plate 73 is connected to the top of the lifting device 76. The air pump 74 is installed at the front end of the cooling pipe 75 and is connected to the front end of the housing 71. The lifting device 76 is fixed to the inside of the housing 71. The cross-section of the housing 71 is in the shape of a "U". The sealing plate 73 has lifting devices 76 at both ends of its bottom. The air pump 74 and the cooling pipe 75 are set at the same level at the front end of the housing 71. The overall size of the sealing plate 73 is the same as the front end size of the heating window 5.
[0031] Please see Figure 5The self-heating device of the food vending machine includes a lifting device 76 comprising a body 761, a servo motor 762, a transmission roller 763, a lifting platform 764, a driven roller 765, and a synchronous belt module 766. The servo motor 762 is mounted at the front end of the body 761 and is connected to the front end of the transmission roller 763 via a coupling. The transmission roller 763 is frictionally driven to the top of the synchronous belt module 766. The transmission roller 763 is rotatably connected to the interior of the body 761. The lifting platform 764 is connected to the outer side of the synchronous belt module 766 and slidably connected to the interior of the body 761. The lifting platform 764 is connected to the bottom of the sealing plate 73. The driven roller 765 is rotatably connected to the inside of the body 761. The driven roller 765 is frictionally driven to the bottom of the synchronous belt module 766. The drive roller 763 and the driven roller 765 are arranged parallel to each other at the upper and lower ends of the synchronous belt module 766. The drive roller 763 and the driven roller 765 are of the same model and size, which is conducive to the rotational cooperation of the drive roller 763 and the driven roller 765 and ensures that the drive roller 763 and the driven roller 765 can smoothly drive the synchronous belt module 766 to rotate. The left end of the body 761 is provided with a rectangular guide groove to ensure that the body 761 cooperates to restrict the front end of the lifting platform 764.
[0032] When in use, place the sales cabinet 1 horizontally on the ground to support the equipment. Manually operate the operation screen 2, and control the intelligent shelf 3 to extend and retract, so that the intelligent shelf 3 can release the goods and the food slides down into the inside of the retrieval window 4, ensuring that the staff can take out the goods from the retrieval window 4 and put the food into the inside of the heating window 5.
[0033] When the servo motor 762 is started, the transmission roller 763 is driven to rotate, so that the transmission roller 763, the driven roller 765 and the synchronous belt module 766 are subjected to frictional transmission. The synchronous belt module 766 drives the lifting platform 764 to move up and down along the body 761, so that the lifting platform 764 pushes the sealing plate 73 to move up and down. Then, the lifting device 76 is started to push the sealing plate 73 to move up and down, so that the sealing plate 73 can move to the outside of the heating window 5, and play a role in shielding and covering the heating window 5, thereby preventing the rapid diffusion of hot air during the heating process.
[0034] After the food is heated, the vacuum pump 74 is activated to draw the hot air out of the heating window 5 through the cooling pipe 75, allowing the internal temperature of the heating window 5 to cool down quickly. This prevents workers from being burned when removing the food. Furthermore, the sealing device 7 seals the front end of the heating window 5, guiding the hot air inside and preventing it from spreading rapidly. This improves the utilization rate of heat in the air and solves the problem of heat loss caused by the easy diffusion of hot air during the heating process in the original equipment.
