Description

Technical Field

[0001] The utility model belongs to the technical field of special medical food testing, in particular to a special medical food stability test box. Background Art

[0002] Formulated foods for special medical purposes refer to specially processed and prepared foods to meet the special needs of people with limited food intake, digestive and absorption disorders, metabolic disorders or specific disease states for nutrients or diets. Formulated foods for special medical purposes are foods, not medicines, but they are not ordinary foods eaten by normal people. This type of food must be used under the guidance of a doctor or clinical nutritionist. It can be used alone or together with ordinary foods or other special dietary foods. During its testing process, the test environment requirements are very high, and high temperature, low temperature or wet heat tests are often required to create a long-term stable temperature, humidity and light environment required for its stable failure evaluation in a scientific way.

[0003] During the experimental stage, special medical purpose formula foods need to be tested in multiple different environments in the test box. However, the existing test boxes for testing stability are not intelligent enough. During one unpacking process, they can often only meet the test of one environment. After the test in one environment is completed, the box needs to be opened, and then the environment inside the box needs to be changed for the next test. This requires frequent opening of the box door, which will cause certain errors in the drug testing. At the same time, most test boxes have a small sample capacity, and placing more samples may affect the test results. Therefore, we propose a special medical food stability test box to solve this problem. Utility Model Content

[0024] See also Figure 1-3 As shown, the utility model is a stability test box for special medical food, including a test cabinet 1, and also includes:

[0025] The driving assembly is symmetrically arranged on the left and right sides of the interior of the test cabinet 1. A placement assembly for increasing the experimental sample capacity is arranged on the inner side of the driving assembly. The driving assembly can drive the placement assembly to move up and down. The driving assembly includes a first motor 6, a screw rod 7, a moving block 10 and a lifting plate 12. The first motor 6 is symmetrically distributed and fixed on the upper end surface of the test cabinet 1. The screw rod 7 is symmetrically distributed and rotatably connected to the interior of the test cabinet 1, and one end of the screw rod 7 is fixedly connected to the output end of the first motor 6. The moving block 10 is diagonally threaded and connected to the outside of the screw rod 7, and the moving block 10 is slidably connected to the inner wall of the test cabinet 1. The lifting plate 12 is fixed on the inner side of the moving block 10, and the lifting plates 12 on both sides can be respectively fitted with the upper and lower ends of the partition body 11. The screw rod 7 can be driven to rotate by the first motor 6, and then the moving block 10 can drive the lifting plate 12 to move up and down along the linear direction of the screw rod 7 as the screw rod 7 rotates, so as to facilitate subsequent testing.

[0026] The partition body 11 is arranged at the central position of the interior of the test cabinet 1, and the cross section of the partition body 11 is an "I"-shaped structure. The interior of the test cabinet 1 is diagonally provided with an environmental chamber 13 and an environmental chamber 2 14, and the environmental chamber 13 and the environmental chamber 13 are located at the upper end of the interior of the test cabinet 1, and the environmental chamber 2 14 is located at the lower end of the interior of the test cabinet 1. The detection environments set by the environmental chamber 13 and the environmental chamber 2 14 are different. An exhaust system and a purification system are arranged inside them. The first motor 6 on both sides can drive the screw rod 7 to rotate, and then the moving block 10 can drive the subsequent placement components to move up and down with the lifting plate 12. The lifting plates 12 on both sides can fit with the upper and lower ends of the partition body 11 respectively, so as to ensure the sealing effect of the environmental chamber 13 and the environmental chamber 2 14. When the sample is in the environmental chamber 2 14, the lifting plate 12 on both sides can be fitted with the upper and lower ends of the partition body 11. After the test is completed, the installation base plate 8 and the lifting plate 12 can be moved upward to fully fit with the partition body 11. After standing still, the volatile gases inside the environmental chamber 14 are purified through the exhaust system and purification system inside the environmental chamber 14. The exhaust system includes a fan and a sealing valve. The sealing valve can ensure the sealing effect of the environmental chamber, and the fan can extract the volatile gases of the samples inside the environmental chamber 13 and the environmental chamber 2 14 and discharge them to the purification system. The purification system is equipped with multiple layers of filter screens and odor adsorbents to thoroughly filter the gases. After the other group of samples is tested in the environmental chamber 13, under the same operation, the exhaust system and purification system inside the environmental chamber 13 purify the volatile gases inside. Then, the two groups of test samples enter different test environments for testing again when the screw 7 rotates again, making the equipment more intelligent and the test efficiency higher.

[0027] Furthermore, the placement assembly includes a mounting base plate 8, a second motor 9 and a rotating cylinder 15, a placement disc 16 and a placement circular groove 17. The mounting base plate 8 is fixed to the lower end surface of the lifting plate 12, and the mounting base plate 8 can move up and down with the lifting plate 12. The rotating cylinder 15 is rotatably connected to the upper end surface of the mounting base plate 8. The second motor 9 is fixed to the central position of the lower end surface of the mounting base plate 8, and the output end of the second motor 9 is fixedly connected to the rotating cylinder 15. The placement disc 16 is linearly distributed and sleeved on the outside of the rotating cylinder 15, and the placement disc 16 is linearly distributed and sleeved on the outside of the rotating cylinder 15. The diameter of the disk 6 decreases from bottom to top, which can greatly increase the number of test samples and make the equipment more practical. The placement circular grooves 17 are circumferentially distributed and opened on the upper end surface of the placement disk 16. The placement circular grooves 17 can limit the bottom of the sample to prevent the sample from moving and affecting the test effect. Then, the second motor 9 can drive the rotating cylinder 15 to rotate, and then the rotating cylinder 15 drives the external placement disk 16 to rotate synchronously, so that all samples inside can be heated or moistened more evenly, thereby improving the test effect of the sample.

[0028] A vacuum pump 2 is provided on the outside of environmental chamber 1 13 and environmental chamber 2 14, and the output ends of the two sets of vacuum pumps 2 are respectively sealed and connected to the inside of environmental chamber 1 13 and environmental chamber 2 14 through pipelines. The air inside environmental chamber 1 13 and environmental chamber 2 14 can be respectively extracted by the provided vacuum pump 2.

The placement circular groove 17 can limit the bottom of the sample to prevent the sample from moving and affecting the test effect. The placement disk 16 is linearly distributed and sleeved on the outside of the rotating cylinder 15, and the disk diameter of the placement disk 16 decreases from bottom to top, which can greatly increase the number of test samples and make the equipment more practical. The second motor 9 can drive the rotating cylinder 15 to rotate, and then the rotating cylinder 15 drives the external placement disk 16 to rotate synchronously, so that all samples inside it can be heated or damped more evenly, thereby improving the test effect of the sample;

[0030] In addition, the first motors 6 on both sides can drive the screw rod 7 to rotate, and then the moving block 10 can drive the subsequent placement components to move up and down with the lifting plate 12. The lifting plates 12 on both sides can respectively fit with the upper and lower ends of the partition body 11, so as to ensure the sealing effect of the environmental chamber 13 and the environmental chamber 2 14. After the sample is tested in the environmental chamber 2 14, the installation base plate 8 and the lifting plate 12 can move upward and fit completely with the partition body 11.

After another group of samples is tested in the environmental chamber 13, under the same operation, the exhaust system and purification system inside the environmental chamber 13 purify the volatile gas inside. Then, the two groups of test samples enter different test environments for testing again when the screw rod 7 rotates again. At the same time, the changes of samples under various test environments can be compared and observed in real time. The equipment is more intelligent and the testing efficiency is higher.
