Description

Technical Field

[0001] This utility model relates to the field of low-temperature preservation technology, and in particular to a vacuum low-temperature preservation device with sterilization effect. Background Technology

[0002] Vacuum cryogenic preservation equipment is a technology used for food preservation. It combines vacuum and cryogenic technologies to extend the shelf life of food and maintain its original quality. The basic principle of vacuum cryogenic preservation technology is to lower the temperature and pressure in a vacuum environment, typically below room temperature, to further inhibit the activity of microorganisms. Low temperatures also slow down the activity of enzymes in food, thereby extending its shelf life.

[0003] Existing freshness-locking equipment has high manufacturing and maintenance costs, and its preservation effect is not ideal. Moreover, the equipment occupies a lot of space, has high installation costs, and is not convenient for movement and transportation.

[0004] An existing patent (publication number: CN217826587U) discloses a vacuum low-temperature preservation device, which includes a housing with self-locking casters rotatably connected to the lower surface of the housing. A sealing door is hinged to one side of the housing, and a touch screen is fixedly installed on the sealing door. An observation port is provided on the sealing door. The housing contains a storage compartment and a freezer compartment. It uses activated carbon adsorption packs to absorb odors in the preservation compartment, preventing food spoilage due to odors carried during storage. A vacuum pump extracts air from the preservation compartment, reducing the oxygen content and thus extending the food's preservation time and improving its preservation effect.

[0005] To address the aforementioned issues, while existing patents have proposed solutions that can extract air from the preservation chamber using a vacuum pump, thereby reducing the oxygen content and extending the food's shelf life and improving preservation, a significant problem exists: after the preservation chamber is evacuated, the extraction pipe is not effectively sealed. If the vacuum pump is used for an extended period, leading to a decrease in the seal, external air may enter the equipment, affecting the preservation effect and failing to guarantee long-term preservation quality. Summary of the Invention

[0006] The purpose of this invention is to provide a vacuum low-temperature preservation treatment device with sterilization effect, which can extract the air from the preservation chamber and, under the action of the spring's own elasticity, push the movable rod to reset, thereby making the sealing plate and the fixed plate contact and sealing the flow limiting component. This can prevent external air from entering the preservation chamber and achieve a good vacuum effect, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a vacuum low-temperature preservation treatment device with sterilization effect, comprising a device shell, universal wheels fixed to the lower surface of the device shell by bolts, a vacuuming mechanism for vacuuming the interior at the upper end of the device shell, a placement mechanism for placing food on the left side of the device shell, and a protective plate hinged to the outer wall of the device shell.

[0008] The vacuum pumping mechanism includes a vacuum pump, which is fixed to the upper part of the equipment housing by bolts. The input end of the vacuum pump is connected to a flow limiting component, and one end of the flow limiting component is connected to a connector. An activated carbon plate is installed inside the connector, and a fixing plate is fixed to the inner wall of the flow limiting component. A vent hole is opened inside the fixing plate.

[0009] Preferably, a sealing plate is disposed on the right side of the fixing plate, and two movable rods that penetrate the interior of the fixing plate are fixed to the side wall of the sealing plate.

[0010] Preferably, the outer surface of the movable rod is fitted with a spring that abuts against the fixed plate, and the output end of the vacuum pump is connected to an exhaust pipe.

[0011] Preferably, two protective nets are fixed to the side wall of the equipment housing, and a compressor is fixed to the lower end of the inside of the equipment housing by screws.

[0012] Preferably, an ultraviolet germicidal lamp is fixed vertically inside the housing of the device by screws.

[0013] Preferably, the placement mechanism includes three placement plates, all of which are placed inside the equipment housing, and each of the three placement plates has a locking strip fixed to both sides.

[0014] Preferably, one side of the card strip is slidably connected to a card block fixed to the inner wall of the equipment housing, and the inner surface of the equipment housing is fixed with a heat insulation cotton board.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The vacuum mechanism can extract the air from the freshness compartment, and the spring's elasticity will push the movable rod to reset, thereby making the sealing plate and the fixed plate contact and sealing the flow limiting component.

Detailed Implementation

[0025] 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.

[0026] This utility model provides a technical solution:

[0027] Please see Figures 1 to 4 A vacuum low-temperature preservation treatment device with sterilization effect includes a device shell 1. The lower surface of the device shell 1 is fixed with casters 2 by bolts. The upper part of the inside of the device shell 1 is provided with a vacuuming mechanism for vacuuming the inside. The left side of the inside of the device shell 1 is provided with a placement mechanism for placing food. The outer wall of the device shell 1 is hinged with a protective plate 8.

[0028] The vacuum pump mechanism includes a vacuum pump 3, which is fixed to the upper part of the equipment housing 1 by bolts. The input end of the vacuum pump 3 is connected to a flow restrictor 31. One end of the flow restrictor 31 is connected to a connector 32. An activated carbon plate 33 is installed inside the connector 32. A fixing plate 34 is fixed to the inner wall of the flow restrictor 31. A vent hole 35 is opened inside the fixing plate 34. A sealing plate 36 is placed on the right side of the fixing plate 34. Two movable rods 37 that penetrate the interior of the fixing plate 34 are fixed to the side wall of the sealing plate 36. A spring 38 that abuts against the fixing plate 34 is sleeved on the outer surface of the movable rods 37. An exhaust pipe 39 is connected to the output end of the vacuum pump 3. Two protective nets 4 are fixed to the side wall of the equipment housing 1. A compressor 5 is fixed to the lower part of the equipment housing 1 by screws.

[0029] By adopting the above technical solution, before using the vacuum low-temperature preservation equipment with sterilization effect, the outer shell 1 of the equipment is moved to a suitable position by the casters 2. By opening the protective plate 8, the food to be preserved can be placed on the placement plate 7. Then, the protective plate 8 is closed, and the vacuum pump 3 is started. The air in the preservation chamber of the equipment is extracted through the connector 32. The activated carbon plate 33 installed in the connector 32 can absorb odors in the air, playing a certain role in deodorizing. When the air is extracted, it passes through the flow restrictor 31 and pushes the sealing plate 36 to move. The sealing plate 36 drives the movable rod 37 to move and compress the spring 38. At this time, the vent 35 on the sealing plate 36 and the fixed plate 34 separate. This ensures that air can be extracted normally and discharged to the outside through the exhaust pipe 39 on the vacuum pump 3. After the vacuum is completed, the spring 38 will push the movable rod 37 to reset under its own elasticity, thereby making the sealing plate 36 and the fixed plate 34 contact and seal the flow limiting component 31. This can prevent outside air from entering the preservation chamber and achieve a good vacuum effect. The compressor 5 and condenser are set up to work together. The compressor 5 is responsible for providing the refrigerant required for refrigeration, and the condenser is responsible for dissipating the heat in the refrigerant to achieve a low temperature environment. The evaporator is fixed to the inner wall of the preservation chamber and reduces the temperature in the preservation chamber to the required level through the circulation of refrigerant. The protective net 4 can protect the internal parts of the equipment.

[0030] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, an ultraviolet germicidal lamp 6 is fixed vertically inside the equipment housing 1 by screws. The placement mechanism includes a placement plate 7, and there are three placement plates 7. All three placement plates 7 are placed inside the equipment housing 1. Each of the three placement plates 7 has a locking strip 71 fixed on both sides. One side of the locking strip 71 is slidably connected to a locking block 72 fixed to the inner wall of the equipment housing 1. An insulation cotton board 73 is fixed to the inner surface of the equipment housing 1.

[0031] By adopting the above technical solution, the ultraviolet germicidal lamp 6 can sterilize the inside of the preservation chamber, destroy the cell structure of microorganisms, and thus ensure the safety of food. The heat insulation cotton board 73 can keep the inside warm. With the help of the clip 72, the placement board 7 can be disassembled by the clip 71 on the placement board 7, which facilitates the cleaning of the inside.

[0032] Working principle: Place the food requiring preservation onto the placement plate 7, close the protective plate 8, and the vacuum pump 3 extracts air from the preservation chamber through the connector 32. As the air is extracted, it passes through the flow restrictor 31, pushing the sealing plate 36 to move. This causes the sealing plate 36 to move the movable rod 37, compressing the spring 38. After vacuuming, the spring 38's elasticity pushes the movable rod 37 back to its original position, causing the sealing plate 36 to contact the fixed plate 34, sealing the flow restrictor 31. This prevents external air from entering the preservation chamber. The compressor 5... The condenser is responsible for providing the refrigerant needed for cooling, while the condenser is responsible for dissipating the heat in the refrigerant to achieve a low-temperature environment. The evaporator is fixed to the inner wall of the fresh food storage room and reduces the temperature inside the fresh food storage room to the required level through the circulation of the refrigerant. The protective net 4 can protect the internal parts of the equipment, while the ultraviolet germicidal lamp 6 can sterilize the inside of the fresh food storage room, destroying the cell structure of microorganisms and thus ensuring the safety of food. The insulation cotton board 73 can keep the inside warm. The placement board 7 can be disassembled by using the clips 71 set on the placement board 7 and the cooperation of the clips 72.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
