[0002] A vending machine is a machine that can automatically deliver goods after payment. It is a commonly used equipment in commercial automation. It is not restricted by time and place, can save manpower and facilitate transactions. It is a new form of commercial retail, also known as a 24-hour mini supermarket. Vending machines have greatly facilitated people's daily shopping needs.

[0003] Takeaways often require a long wait, and the production process of the takeaways cannot be seen, and the quality, taste and flavor of the takeaways cannot be guaranteed. Under this circumstance, various types of lunch box vending machines have emerged, and the best among the lunch box vending machines are the lunch box vending machines with heating function.

[0004] In the prior art, in order to ensure the quality of lunch boxes, a freezer for keeping lunch boxes fresh is usually built into the vending machine to reduce the probability of food spoilage. At the same time, in order to avoid cold air leakage, a liftable cabinet door will be set at the exit of the freezer, and a sealing strip will be installed at the exit to ensure the sealing of the cabinet door after it is closed, thereby reducing energy consumption. However, in actual use, the inventor found that due to the need to ensure the sealing of the cabinet door after it is closed, the sealing strip needs to be closely matched with the cabinet door, resulting in the cabinet door pulling the sealing strip during the lifting process, making the sealing strip prone to deformation and dislocation, affecting the service life of the sealing strip, and generating unnecessary noise. Therefore, the utility model proposes a new isolation door structure and a vending machine. Summary of the invention

DETAILED DESCRIPTION

[0025] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] In this embodiment, refer to Figure 1-Figure 6 A specific implementation of a vending machine includes a heating cabinet 2 and a freezing cabinet (not shown), a material inlet 201 is provided on one side of the heating cabinet 2, a material outlet aligned with the material inlet 201 is provided on the freezing cabinet, and an isolation door structure 3 is provided between the material inlet 201 and the material outlet.

[0027] The isolation door structure 3 includes a sealing door and a lifting assembly for driving the sealing door to move up and down. The sealing door includes a door core 31 and a sealing cover plate 32 arranged on the door core 31. The sealing cover plate 32 is telescopically installed on the door core 31 through four guide columns 33, so that the sealing cover plate 32 can be smoothly moved sideways to avoid the sealing cover plate 32 from tilting and affecting the sealing effect. A reset member 35 for connecting with the sealing cover plate 32 is arranged in the door core 31; an outward expansion bracket 36 is arranged at the lower end of the lifting assembly, and an outward expansion member for cooperating with the sealing cover plate 32 is arranged at the upper end of the outward expansion bracket 36.

[0028] like Figure 4-5 As shown, in this embodiment, the external expansion member adopts a roller 37, and the roller 37 is rotatably installed on the upper end of the external expansion bracket 36. The rotatable roller 37 reduces the resistance (friction) of the movement of the external expansion member. At the same time, the circular roller 37 is more convenient to guide into the inner side of the sealing cover plate 32, thereby reducing the probability of jamming.

[0029] Further, such as Figure 6 As shown, the outer expansion piece may also be a rectangular slider 38 with a guide structure at the end, so as to achieve the purpose of opening the sealing cover plate 32 .

[0030] In this embodiment, a positioning protrusion 321 for cooperating with the external expansion member is provided in the middle of the sealing cover plate 32. A guiding inclined surface for guiding the external expansion member is provided at one end of the positioning protrusion 321.

[0031] Furthermore, two sealing cover plates 32 are symmetrically arranged, and both ends of the reset member 35 are respectively connected to the two sealing cover plates 32, and the two sealing cover plates 32 are respectively matched with the material inlet 201 and the material outlet. The reset member 35 is a tension spring.

[0032] Furthermore, the lifting assembly includes a lifting bracket 39 and a driving motor 34. The door core 31 is installed on the lifting bracket 39 in a liftable manner. The lifting bracket 39 includes a screw rod 391 for connecting to the driving motor 34 and guide rods 392 respectively arranged on both sides of the screw rod 391.

[0033] Furthermore, sealing rings 5 ​​for cooperating with the sealing cover plate 32 are correspondingly arranged on the outer edges of the material inlet 201 and the material outlet.

[0034] The isolation door structure 3 provided by the utility model can, under the push of the external expansion member, the sealing cover plate 32 can be laterally displaced along the guide column 33, so that the sealing door can press the sealing ring 5 at the material port after it is lowered. When the sealing door is raised, the sealing cover plate 32 can be pulled inward by the reset member 35, thereby avoiding the pulling and affecting the sealing ring 5, avoiding deformation, misalignment and noise, thereby increasing the service life of the sealing strip and ensuring the sealing effect of the cabinet.

[0035] In actual use, when the lifting assembly drives the sealing door to descend to the first height, the outer expansion piece abuts against the inner side of the sealing cover plate 32; when the lifting assembly drives the sealing door to descend to the second height, the guide column 33 guides the sealing cover plate 32 to move sideways, and simultaneously drives the sealing cover plate 32 to move outward, until the outer expansion piece abuts against the positioning protrusion 321, the sealing door moves sideways to the sealing position, and the sealing cover plate 32 and the sealing ring 5 fit tightly; when the lifting assembly drives the sealing door to rise to the first height, the guide column 33 guides the sealing cover plate 32 to move sideways, and the reset piece 35 simultaneously drives the sealing cover plate 32 to move inward, until the outer expansion piece separates from the positioning protrusion 321, and the sealing cover plate 32 separates from the sealing ring 5. In this way, the lifting action of the sealing door is completed.

[0036] The above is only a preferred embodiment of the utility model, and does not limit the utility model in any form. Although the utility model is disclosed as a preferred embodiment as above, it is not used to limit the utility model. Any technician familiar with this profession can make some changes or modifications to equivalent embodiments of equivalent changes by using the technical content disclosed above without departing from the scope of the technical solution of the utility model.
