Description

Technical Field

[0001] The utility model relates to the technical field of sealing, in particular to a sealing structure for an electric field fresh-keeping cabinet. Background Art

[0002] With the development of urbanization, people's lives are becoming more and more convenient. Fresh-keeping cabinets on the market can be divided into air-cooled open fresh-keeping cabinets and direct-cooled glass door fresh-keeping cabinets. Their function is to slow down the activity of bacteria inside the food by lowering the temperature, thereby extending the shelf life. Currently, the most common fresh-keeping cabinets on the market are cooked food fresh-keeping cabinets, fresh meat fresh-keeping cabinets, yogurt fresh-keeping cabinets and clean vegetable fresh-keeping cabinets. The electric field fresh-keeping cabinet is sealed by the cabinet body and the cabinet door, and then the voltage is increased through the Dormancy control device, and an electric field space is generated in the fresh-keeping cabinet. The electric field causes the bacterial cell membrane to perforate, thereby inhibiting The electric field can control the bacterial reproduction of fresh meat and seafood ingredients, and lower the freezing point of ingredients, thereby extending the shelf life of meat and seafood ingredients. The electric field can also produce trace amounts of ozone, which reacts with the ethylene released by fruits and vegetables to generate carbon dioxide, thereby inhibiting the ripening and aging of fruits and vegetables. Carbon dioxide can inhibit the reproduction of bacteria, thereby extending the shelf life of fruits and vegetables. The electric field inactivates enzymes, weakening the respiration intensity of fruits and vegetables, delaying aging. The weakening of fruit and vegetable respiration reduces the consumption of water and nutrients in ingredients, thereby extending the shelf life of fruits and vegetables. Its many functions make the use of electric field fresh-keeping cabinets more and more widespread.

[0003] The cabinet body and cabinet door of the existing electric field fresh-keeping cabinet are mostly closed by adsorbing each other with magnets, and then the cabinet body and the cabinet door are sealed by a single sealing strip. However, the sealing strip is prone to deformation after long-term use, which can easily lead to a gap between the sealing strip and the cabinet body, causing bacteria to enter and cause food spoilage.

DETAILED DESCRIPTION

[0021] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0022] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which the utility model belongs.

[0023] Reference Figure 1-5 A sealing structure for an electric field fresh-keeping cabinet comprises a rectangular sealing block 1 and a rectangular sealing fitting pad 2. A rectangular slot 3 is provided on the front of the rectangular sealing block 1. The inner walls on both sides of the rectangular slot 3 are provided with symmetrically distributed sealing extrusion grooves 4. The cross-section of the sealing extrusion groove 4 is arc-shaped. An arc-shaped extrusion airbag 5 is fixedly connected to the inner wall of the sealing extrusion groove 4. After the arc-shaped extrusion airbag 5 is input with gas, its outer side is fixed to the sealing extrusion groove 4, and its inner side surface is inflated and deformed. An arc-shaped deformation pad 6 is fixedly connected to the rear inner wall of the rectangular slot 3.

[0024] An extrusion cavity 7 is arranged between the inner surface of the arc-shaped deformation pad 6 and the rectangular slot 3. The inner surface of the arc-shaped deformation pad 6 is fixedly connected with reset springs 8 distributed in a rectangular array. The reset elastic force of the reset spring 8 drives the arc-shaped deformation pad 6 to support and reset. The elastic force of the reset spring 8 is smaller than the magnetic attraction force between the cabinet body and the cabinet door. One ends of the multiple reset springs 8 are fixedly connected to the rear inner wall of the rectangular slot 3. The rear inner wall of the rectangular slot 3 is provided with symmetrically distributed guide holes 9. One end of the guide hole 9 is connected to the inner wall of the arc-shaped extrusion airbag 5. The guide hole 9 serves to transport the airflow in the extrusion cavity 7 to the inside of the arc-shaped extrusion airbag 5.

[0025] A symmetrically distributed extrusion slope 10 is provided at the front end of the rectangular slot 3, a rectangular sealing plug 11 is fixedly connected to the back of the rectangular sealing pad 2, and an arc-shaped sealing block 12 adapted to the sealing extrusion groove 4 is provided on the inner and outer sides of the rectangular sealing plug 11. The extrusion slope 10 facilitates the arc-shaped sealing block 12 to be inserted into the rectangular slot 3 and enter the sealing extrusion groove 4, and the rectangular sealing pad 2 plays a role in further fitting and sealing.

[0026] By setting up the rectangular sealing block 1 and the rectangular sealing fitting pad 2 for use together, the arc-shaped deformation pad 6 is squeezed by the rectangular sealing plug-in block 11, so that the gas in the extrusion cavity 7 is transported to the inside of the arc-shaped extrusion airbag 5 through the guide hole 9 for expansion, so that the arc-shaped extrusion airbag 5 cooperates with the arc-shaped sealing block 12 to perform a tight fit and seal, thereby avoiding the problem of bacteria entering and causing food spoilage.

[0027] Working principle: Step 1, install the rectangular sealing pad 2 on the back of the cabinet door, and then install the rectangular sealing block 1 on the front of the cabinet. By closing the cabinet door, the rectangular sealing pad 2 drives the rectangular sealing plug 11 to be inserted into the rectangular slot 3, and the setting of the extrusion slope 10 facilitates the rectangular sealing plug 11 to drive the arc-shaped sealing block 12 to be squeezed into the sealing extrusion groove 4;

[0028] Step 2: After the rectangular sealing plug 11 is inserted into the rectangular slot 3, the rectangular sealing plug 11 squeezes the arc-shaped deformation pad 6, causing the return spring 8 to contract, and the gas in the extrusion cavity 7 is transported to the inside of the arc-shaped extrusion airbag 5 through the guide hole 9. The arc-shaped extrusion airbag 5 expands due to the gas transport, so that its inner surface is squeezed and fitted with the arc-shaped sealing block 12, thereby enhancing the sealing between the cabinet body and the cabinet door;

[0029] Step three, the arc-shaped sealing block 12 is squeezed and limited by the arc-shaped extrusion airbag 5 and the sealing extrusion groove 4, and the elastic force of the reset spring 8 is limited. When the cabinet body and the cabinet door are opened by external force, the elastic force of the reset spring 8 drives the arc-shaped deformation pad 6 to reset, and the gas in the arc-shaped extrusion airbag 5 is drawn into the extrusion cavity 7 through the guide hole 9.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model, and they should all be included in the scope of the claims and specification of the utility model.
