[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0022] Please see Figure 1-5 As shown, a food sterilization device based on plasma technology includes a housing 1. Two parallel sterilization plates 2 are installed inside the housing 1. An adjustment mechanism 3 is installed on the outside of the housing 1. The adjustment mechanism 3 includes sliders 305. Two sliders 305 are slidably connected to both sides of the housing 1. One end of each slider 305 extends to the inside of the housing 1 and connects to the end of the sterilization plate 2. The two sterilization plates 2 are slidably connected to the inside of the housing 1 through the two sliders 305. The other ends of the two sliders 305 are connected through a connecting plate 301. A limit mechanism 4 is installed on the outside of the housing 1.

[0023] As a technical optimization of this utility model, a plurality of connecting springs 306 are installed on the top of one of the sterilization plates 2. The tops of the plurality of connecting springs 306 are respectively connected to the inner side of the top of the box body 1. The installation of the plurality of connecting springs 306 facilitates the suspension connection of the sterilization plate 2 and provides assistance when the sterilization plate 2 rises.

[0024] As a technical optimization of this utility model, drive rods 303 are rotatably connected to both sides of one end of the housing 1 via fixed shafts 309. Movable grooves 307 are provided on the outer side walls of the top ends of the two connecting plates 301. Guide wheels 308 are rotatably connected inside the movable grooves 307. One end of the two drive rods 303 is rotatably connected to the two guide wheels 308. With the cooperation of the movable grooves 307, the two drive rods 303 drive the two guide wheels 308, which facilitates the lifting and lowering control of the connecting plates 301, making the operation convenient and labor-saving.

[0025] As a technical optimization solution of the present utility model, the other ends of the two driving rods 303 are rotatably connected through a connecting rod 304. The fixed shaft 309 is located at one-third of the driving rod 303. Through the installation of the connecting rod 304, it is beneficial to synchronously drive and control the two driving rods 303, and by using the lever principle, the operation is more labor-saving.

[0026] As a technical optimization solution of the present utility model, fixing frames 310 are respectively installed on both sides of the box body 1. The connecting plate 301 is slidably connected to the inner side of the fixing frame 310. Dust covers 302 are respectively installed at both ends of the connecting plate 301. The end of the dust cover 302 is connected to the inner side wall of the fixing frame 310. Through the installation of the fixing frame 310, it is beneficial to connect the dust cover 302, thereby realizing the shielding of the slider 305 and playing a safety protection role.

[0027] As a technical optimization solution of the present utility model, the limiting mechanism 4 includes fixing plates 401. Two fixing plates 401 are fixedly connected to the edge of the end of the box body 1. Arc-shaped guide grooves 404 are provided on the outer side walls of the two fixing plates 401. The cross-section of the guide groove 404 is a "convex" structure. A limiting block 403 is slidably connected inside the guide groove 404. Screws 402 are respectively threadedly connected to the two driving rods 303. One end of the screw 402 extends into the guide groove 404 and is rotatably connected to the limiting block 403. Through the installation of the fixing plate 401, it is beneficial to open the guide groove 404. By rotating the screw 402, the screw 402 pulls the limiting block 403, which is beneficial to limit the limiting block 403 inside the guide groove 404 and keep the driving rod 303 in a limited state. On the contrary, when the screw 402 is loosened, the limiting block 403 can slide inside the guide groove 404, facilitating the swing control of the driving rod 303.

[0028] As a technical optimization solution of the present utility model, the screw 402 is a cylindrical "T" - shaped structure. Multiple annularly distributed grooves 406 are provided on the outer side wall of one end of the screw 402, which is beneficial to drive and control the screw 402, and it is comfortable to hold and not easy to slip during driving.

[0029] As a technical optimization solution of the present utility model, the limiting block 403 is a cylindrical structure. The edge of one end of the limiting block 403 is a toothed structure, which is beneficial to the smooth rolling of the limiting block 403 inside the guide groove 404 and is in close contact with the inside of the fixing plate 401, increasing the friction force and having a better limiting effect.

[0030] As a technical optimization of this utility model, two drive rods 303 are vertically fixedly connected to a fixing sleeve 405 on opposite sides. One end of the fixing sleeve 405 is slidably connected to the outer side of the fixing plate 401, and one end of the screw 402 is rotatably connected to the inside of the fixing sleeve 405. By installing the fixing sleeve 405, when the limiting block 403 abuts against the inner side of the fixing plate 401, one end of the fixing sleeve 405 will also abut against the outer wall of the fixing plate 401, so that the limiting block 403 and the fixing sleeve 405 can firmly clamp the fixing plate 401 and prevent the drive rod 303 from deforming.

[0031] In use, this invention first involves rotating two screws 402, causing the screws 402 to loosen the limiting block 403 inside the guide groove 404, facilitating the rolling of the limiting block 403 within the guide groove 404. Then, the connecting rod 304 is pushed, causing the two driving rods 303 to rotate. With the cooperation of the movable groove 307 and the guide wheel 308, the two driving rods 303 drive and control the two connecting plates 301, enabling the two connecting plates 301 to be adjusted in height. Simultaneously, the two connecting plates 301 control the two sliders 305 to slide on the outside of the housing 1, thereby allowing the height of the two parallel sterilization plates 2 to be adjusted, facilitating the conveying and sterilization of food of different sizes. After adjusting to the appropriate height, rotating the two screws 402 causes the limiting block 403 to engage with the guide groove 404, thus limiting the limiting block 403 and the fixed plate 401, preventing the driving rod 303 from loosening, facilitating stable support for the connecting plate 301, and facilitating subsequent sterilization work.
