Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1-4, including a box body 1, a fixing frame 3, which is fixed to the top of the inner wall of the box body 1, and the bottom of the fixing frame 3 is two groups of symmetrically inclined support rods; a mounting ring 4, the top and the bottom of the fixing frame 3 are fixed to each other; a movable sleeve 5 is divided into two groups and is sleeved on the outer ring of the mounting ring 4, and is respectively located on one side separated by the support rods of the fixing frame 3, and the movable sleeve 5 can move along the mounting ring 4, and support plates are fixed on both sides of the movable sleeve 5, and the support plates face the center direction of the box body 1, and mounting holes are opened on the side surfaces of the support plates; a fixing plate 6 is movably installed with the support plates of the movable sleeve 5 through the mounting axes on both sides, the lamp tube 7 is U-shaped, and the opening faces the side away from the mounting ring 4, and a lamp tube mounting frame is fixed inside; the lamp tube 7 is installed in the lamp tube mounting frame inside the fixed plate 6; an angle adjustment mechanism is provided on the side of the movable sleeve 5 to adjust the inclination angle of the fixed plate 6 and the lamp tube 7. The angle adjustment mechanism includes a gear plate 8, a limit plate 9, a movable rod 10 and a gear sleeve 11. The gear plate 8 is fixed on the mounting shaft on one side of the fixed plate 6 and is located on the outside of the movable sleeve 5. The surface of the movable sleeve 5 is close to the gear plate 8 and is fixed to the limit plate 9 by a support rod, and the center axis of the limit plate 9 and the gear plate 8 coincide with each other. A mounting hole is provided on the surface of the limit plate 9, and the movable rod 10 is inserted into the mounting hole of the limit plate 9. A compression spring is installed on the outside of the movable rod 10, and the gear sleeve 11 is fixed to one end of the movable rod 10 close to the gear plate 8, and the gear sleeve 11 is meshed with the gear plate 8. One end of the compression spring is fixed to the side wall of the limit plate 9, and the other end is fixed to the surface of the gear sleeve 11. A guide block is fixed on the surface of the gear sleeve 11 corresponding to the position of the support rod of the limit plate 9. A guide groove is provided on the side of the support rod close to the gear sleeve 11. By The guide block of 1 and the guide groove of the support rod of the limit plate 9 are installed with each other, so that the gear sleeve 11 can prevent the movable rod 10 from rotating automatically while moving toward the movable sleeve 5. Since the gear sleeve 11 and the gear plate 8 are engaged with each other, when the gear sleeve 11 is locked, the gear plate 8 cannot drive the fixed plate 6 to rotate. When the food is subjected to a strong light irradiation test, the angle of the fixed plate 6 can be adjusted according to the style of the food. When the food has poor fluidity and forms a piled state, there is a height difference between the foods, and the food will have a backlight side that cannot be illuminated. At this time, the movable rod 10 can be pulled away from the gear plate 8 to disengage the gear sleeve 11 from the gear plate 8, thereby rotating the fixed plate 6 around the installation axis, adjusting the inclination angle of the lamp tube 7, and irradiating the food in a straight line, reducing the backlight side of the food, and improving the uniformity of food lighting.

[0027] A movable plate 12 is installed on the side of the movable sleeve 5 away from the fixed plate 6. A rotating shaft is set between the two groups of movable plates 12. The movable sleeve 5 is movably connected to the rotating shaft through a fixed rod, thereby connecting with the two groups of movable plates 12. A torsion spring is arranged on the outer shell of the rotating shaft. A mounting groove is provided on the surface of the movable sleeve 5 corresponding to the position of the movable plate 12, so that the movable plate 12 is in direct contact with the mounting ring 4 through the mounting groove. A positioning block 13 is fixed on the surface of the movable plate 12 corresponding to the position of the mounting ring 4. A plurality of positioning holes 14 are provided on the top and side walls of the mounting ring 4. The positioning blocks 13 are inserted into the positioning holes 14 to fix the movable plate 12. The movable plate 12 is connected to the movable sleeve 5, thereby limiting the movable sleeve 5 from moving with the movement of the movable sleeve 5. The weight of the lamp tube 7 rotates to ensure the support angle of the lamp tube 7. When the food is highly fluid and forms a relatively flat state, the movable plate 12 can be pressed to drive the positioning block 13 to tilt out from the inside of the positioning hole 14. After the positioning block 13 is disengaged from the positioning hole 14, the movable sleeve 5 can rotate freely around the mounting ring 4, and the lamp tube 7 is rotated downward so that the lamp tube 7 faces the food. Then, the positioning block 13 is inserted into the positioning hole 14 on the side wall of the mounting ring 4, and the movable sleeve 5 is fixed. Then, the angles of the two groups of lamp tubes 7 are adjusted so that the two groups of lamp tubes 7 form a straight line parallel to the placement plate 2, which is convenient for straight-line irradiation of food and improves the uniformity of food lighting.

[0028] A protective box is provided at the bottom of the inner wall of the box body 1, and a rotating motor 15 is installed inside the protective box. A placement plate 2 is installed on the top of the protective box. The transmission end of the rotating motor 15 is connected to the bottom of the placement plate 2. The placement plate 2 can be driven to rotate by the rotating motor 15, and the food is placed on the surface of the placement plate 2, so that the food is illuminated by the lamp 7 while rotating, so that the food can be evenly illuminated, thereby improving the accuracy of the test structure.

[0029] A mounting groove is fixed in the middle of the inner wall of the box body 1, and a glass plate 16 is movably installed in the mounting groove. The glass plate 16 can divide the space inside the box body 1, so that the space where the lamp tube 7 is located is divided from the placement plate 2, thereby reducing the impact of the heat generated by the lamp tube 7 on the food.

[0030] Ventilation holes are provided on both sides of the box body 1 corresponding to the position of the fixing frame 3. A ventilation fan 17 is installed in one of the holes, and a filter window 18 is installed on the side away from the ventilation fan 17. The ventilation fan 17 cools the space where the lamp tube 7 is located to reduce the temperature of the lamp tube 7, and the isolation of the glass plate 16 reduces the air circulation in the space where the food is located, thereby reducing the volatility of the food.

[0031] Working principle: Place the special medical food that needs light testing on the surface of the placement plate 2, and adjust the angle of the lamp tube 7 according to the state of the food. When the food is in a relatively flat state, the movable sleeve 5 can be adjusted through the movable plate 12 so that the lamp tube 7 faces the placement plate 2, and then disengage the gear sleeve 11 from the gear plate 8 so that the two groups of lamp tubes 7 are parallel to the placement plate 2, which is convenient for the lamp tube 7 to illuminate things in a straight line. When the food is in a stacked state, rotate the movable sleeve 5 so that the lamp tube 7 is located inside the mounting ring 4, and adjust the angle of the lamp tube 7 according to the height of the food stack, so as to reduce the light shadow surface of the food. Push the gear sleeve 11 through the compression spring so that the gear sleeve 11 engages with the gear plate 8, thereby fixing the inclination angle of the lamp tube 7, and drive the placement plate 2 to rotate through the rotating motor 15, so that the placement plate 2 drives the food to rotate. When the food rotates, the lamp tube 7 can fully illuminate the food, improve the uniformity of food illumination, and ensure the accuracy of the test results.
