Description

Technical Field

[0001] The utility model relates to the technical field of food preservation, in particular to a sampled food pollution-proof preservation cabinet. Background Art

[0002] Sampling food preservation cabinet is a kind of equipment specially used to store and preserve collected food samples. In the food industry and related fields, sampling is a very important task to ensure food quality and safety. After sampling, food samples need to be properly preserved and stored to prevent sample contamination, deterioration or damage, while maintaining the originality and stability of the samples.

[0003] For example, a Chinese utility model patent (CN217893640U) discloses a food sample storage device with a preservation function, which records: "Through a rotatable and fixed fixing rod, when the cabinet door is closed, the fixing rod is reset and inserted into the limit block to lock the upper cabinet door and the lower cabinet door to avoid leakage of the inner temperature due to loose closing, resulting in increased inner temperature and reduced preservation function." It also records: "The cabinet door of the existing preservation cabinet has no locking structure. The cabinet door is closed by adsorption, which causes wear and tear after long-term use, resulting in poor adsorption effect, and the cabinet door cannot be locked. The temperature inside the cabinet leaks, and the inner temperature cannot be guaranteed, resulting in poor preservation effect inside." Technical problems.

[0004] In summary, it can be seen that the prior art utilizes a locking structure added to the cabinet door to prevent the temperature inside the storage cabinet from leaking out. However, this method has the following technical problems: the cabinet door of a traditional sampled food storage cabinet is a whole. During the process of taking and placing sampled food, the internal space of the storage cabinet has a large contact area with the outside world, which causes the temperature inside the storage cabinet to fluctuate greatly during the process of opening and closing the cabinet door, thereby causing bacteria to breed and cause food to be contaminated. For this reason, the present application proposes a sampled food anti-pollution storage cabinet to provide a new technical solution to solve the technical problems mentioned in the above patents. Utility Model Content

[0005] Based on this, it is necessary to provide a sampled food anti-pollution storage cabinet to address the above technical problems. When the operator takes and places the sampled food, he only needs to pull out the movable shell corresponding to the fixed shell where the corresponding food is located, thereby avoiding the large contact area between the interior of the storage cabinet shell and the outside world during the process of taking and placing the food, resulting in large temperature fluctuations, and then causing bacteria to grow and cause food to be contaminated. At the same time, the small contact area between the storage cabinet shell and the outside reduces the entry of external bacteria into the interior of the storage cabinet shell, further reducing the possibility of food contamination. At the same time, when storing items, by turning the fixed handle and pushing the movable shell to deform the rubber pad, and then loosening the fixed handle, the movable shell can be tightly fixed to the inside of the fixed shell, avoiding temperature leakage inside the fixed shell, and improving the stability of the device and the convenience of operation.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0014] As a preferred embodiment of the sampled food anti-contamination preservation cabinet provided by the utility model, the temperature conduction mechanism includes a fixed plate fixedly connected to the top of the fixed outer shell, a heat-conducting column is fixedly connected to the inside of the fixed plate, the heat-conducting column is fixedly connected to the inside of the fixed outer shell, and the placement frame is fixedly connected to a heat-conducting sheet at one end located inside the fixed outer shell.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] The sampled food contamination prevention cabinet provided by the utility model only needs to pull out the movable shell corresponding to the fixed shell where the corresponding food is located during the process of taking and placing the sampled food, thereby avoiding the situation in which the interior of the cabinet shell is in contact with the outside world due to a large contact area with the outside world during the process of taking and placing the food, resulting in large temperature fluctuations and further causing food contamination caused by bacterial growth.

[0027] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0028] As described in the background technology, the door of a traditional sampled food storage cabinet is an integral whole. During the process of taking and placing sampled food, the internal space of the storage cabinet has a large contact area with the outside world, which causes the temperature inside the storage cabinet to fluctuate greatly during the process of opening and closing the cabinet door, thereby causing bacteria to grow and cause food contamination.

[0029] In order to solve this technical problem, the utility model provides a sampled food anti-pollution storage cabinet, which is used to reduce the contamination of sampled food.

[0030] Specifically, please refer to Figure 1-Figure 3 , the sampling food anti-contamination storage cabinet specifically includes:

[0031] The cabinet comprises a storage cabinet shell 1, a plurality of receiving plates 4 are fixedly connected to the interior of the storage cabinet shell 1, a plurality of isolation mechanisms 2 are respectively arranged on the top of the plurality of receiving plates 4, a plurality of temperature conducting mechanisms 3 are arranged on the isolation mechanisms 2, and a plurality of ventilation holes 5 are opened on the receiving plates 4;

[0032] The isolation mechanism 2 includes a fixed shell 6, a placement frame 8, a movable shell 7, a driving assembly, a limiting assembly, and a tight assembly. The fixed shell 6 is fixedly connected to the top of the receiving plate 4, the placement frame 8 is slidably connected to the inside of the fixed shell 6, the outer wall of the placement frame 8 is fixedly connected to the movable shell 7, and the movable shell 7 is movably connected to the inside of the fixed shell 6.

[0033] The sampled food anti-pollution storage cabinet provided by the utility model only needs to pull out the movable shell 7 corresponding to the fixed shell 6 where the corresponding food is located during the process of taking and placing the sampled food, thereby avoiding the situation in which the interior of the storage cabinet shell 1 is in contact with the outside world due to a large contact area with the outside during the process of taking and placing the food, resulting in large temperature fluctuations and further causing food contamination caused by bacterial growth. At the same time, the small contact area between the storage cabinet shell 1 and the outside reduces the entry of external bacteria into the interior of the storage cabinet shell 1, further reducing the possibility of food contamination. At the same time, when storing items, by rotating the fixed handle 10 and pushing the movable shell 7 to deform the rubber pad 15, and then loosening the fixed handle 10, the movable shell 7 can be tightly fixed to the inside of the fixed shell 6, avoiding temperature leakage inside the fixed shell 6, and improving the stability of the device and the convenience of operation.

[0034] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0035] Embodiment 1:

[0036] Please refer to Figure 2-Figure 4 , a sampled food anti-contamination storage cabinet, comprising:

[0037] The driving assembly is rotatably connected to a rotating shaft 9 inside the movable shell 7. One end of the rotating shaft 9 located outside the movable shell 7 is fixedly connected to a fixed handle 10. The fixed handle 10 facilitates the operator to rotate the rotating shaft 9. The fixed handle 10, which is larger than the rotating shaft 9, makes it easier for the operator to rotate the rotating shaft 9.

[0038] The limiting component includes a driving gear 11 fixedly connected to the outer wall of the rotating shaft 9 and located in the movable shell 7, and the upper and lower sides of the driving gear 11 are respectively meshed with driven racks 12. The inner wall of the movable shell 7 is fixedly connected to two limiting frames 13, and the two driven racks 12 are respectively slidably connected to the inner walls of the corresponding limiting frames 13. The outer wall of the rotating shaft 9 and the interior of the movable shell 7 are sleeved with a torsion spring 14. The torsion spring 14 is deformed during the rotation of the fixed handle 10, and then accumulates elastic force. The elastic force is released when the fixed handle 10 is released, so that the driven rack 12 is directly inserted into the corresponding hole groove in the fixed shell 6, reducing the operator's operation and improving the convenience of device operation. The two ends of the torsion spring 14 are respectively fixedly connected to the outer wall of the driving gear 11 and the inner wall of the movable shell 7. Through holes 23 are respectively opened on both sides of the movable shell 7. The driven rack 12 passes through the through hole 23 into the fixed shell 6 and can move left and right relative to each other in the through hole 23.

[0039] The tight assembly includes a fixing frame 16 fixedly connected to the inner wall of the fixed shell 6, and a rubber pad 15 is fixedly connected to the outer wall of the fixing frame 16 and the side close to the movable shell 7. When the movable shell 7 is placed inside the fixed shell 6, the rubber pad 15 is deformed by being squeezed, and then releases elastic force outward, so that the side of the movable shell 7 close to the placement frame 8 is tightly fitted with the rubber pad 15, thereby reducing the temperature leakage and improving the practicability of the device. The side of the movable shell 7 close to the placement frame 8 is tightly attached to the side of the rubber pad 15 away from the fixing frame 16.

[0040] With the above structural design, in the process of storing and retrieving items, by rotating the fixed handle 10, the rotating shaft 9 is driven to rotate, and the driving gear 11 is driven to rotate, so that the torsion spring 14 is deformed accordingly. The rotation of the torsion spring 14 drives the two driven racks 12 to slide in the limiting frame 13 and the through hole 23, and return to the movable shell 7, and then contact the limit between the movable shell 7 and the fixed shell 6, so that the fixed handle 10 can be pulled, and the placement frame 8 is driven by the movable shell 7 to leave the inside of the fixed shell 6 to store and retrieve food. After the sampled food is stored and retrieved, the fixed handle 10 is pushed to push the movable shell 7 and the placement frame 8 back to the inside of the fixed shell 6, and the push is continued, so that the rubber pad 15 is squeezed and deformed to a certain extent, so that the driven rack 12 is aligned with the slot on the fixed shell 6, and the fixed handle 10 is released. Under the action of the elastic force of the torsion spring 14, the driving gear 11 is driven to rotate, so that the two driven racks 12 pass through the through hole 23 and enter the slot in the fixed shell 6, so that the position of the movable shell 7 and the placement frame 8 is limited.

[0041] Embodiment 2:

[0042] The sampled food anti-contamination storage cabinet provided in Example 1 is further optimized, specifically, Figure 5 As shown, the temperature conducting mechanism 3 includes a fixed plate 17 fixedly connected to the top of the fixed shell 6, a heat conducting column 18 is fixedly connected inside the fixed plate 17, the material of the heat conducting column 18 can be copper, the heat conducting column 18 is fixedly connected to the inside of the fixed shell 6, and a heat conducting sheet 19 is fixedly connected to one end of the placement frame 8 located inside the fixed shell 6, the heat conducting sheet 19 increases the contact area between the heat conducting column 18 and the air inside the fixed shell 6, thereby improving the efficiency of heat exchange, and the material of the heat conducting sheet 19 can be copper.

[0043] One end of the heat-conducting column 18 away from the heat-conducting sheet 19 is fixedly connected to a heat-conducting block 20, and a plurality of connecting plates 21 are fixedly connected to the outside of the heat-conducting block 20. A side of the plurality of connecting plates 21 away from the heat-conducting block 20 is fixedly connected to an arc-shaped heat-conducting plate 22. The arc-shaped heat-conducting plate 22 is located above the air vent 5. The arc-shaped heat-conducting plate 22 can better exchange heat with the air passing through the air vent 5, and the arc surface reduces the obstruction to the air flow. The material of the arc-shaped heat-conducting plate 22 can be copper.

[0044] Through the above-mentioned structural design, the heat inside the fixed shell 6 is transferred to the heat conducting plate 19, and then heat is exchanged with the heat conducting block 20 through the heat conducting column 18, and then heat is exchanged with the arc-shaped heat conducting plate 22 through multiple connecting plates 21, so that the temperature inside the cabinet shell 1 and outside the fixed shell 6 is effectively exchanged with the temperature inside the fixed shell 6. On the basis of the direct heat exchange between the fixed shell 6 and the temperature inside the cabinet shell 1 and outside the fixed shell 6, the efficiency of the heat exchange between the two is improved, and the growth of bacteria due to the high temperature inside the fixed shell 6, which in turn causes contamination of food, is avoided, thereby improving the practicality of the device.
