Description

Sealing lids for vacuum tanks

Technical field:

The utility model relates to the technical field of storage tanks, in particular to a sealing cover of a vacuum tank.

Background technique:

With the continuous improvement of living standards, people have higher and higher requirements for the quality of life. In daily life, people often need to store some food, and a gang will use storage tanks. The storage tanks in the present technology generally have a tank body and a cover body. The tank body and the cover body of the most traditional storage tanks are connected by threads. The storage tanks with this structure have poor sealing performance. There are all kinds of bacteria, water and moisture, most of which will cause food to rot and deteriorate, resulting in food waste. Therefore, sealed cans appearing in the market one after another, and now the sealed cans on the market only have a structure of a can and a cover , but the tank and the cover are no longer connected by threads, but are fastened to each other. A silicone sealing ring is arranged on the cover and the tank body, and the internal air of the tank is isolated from the external air through the sealing ring. No gas exchange occurs to prolong the freshness of food. But the sealed can of this kind of structure also has the following defects: there is air in the sealed can, and various bacteria are carried in the air, which will corrode the food in the can.

Therefore, in order to maximize the performance of sealing and keeping fresh, the utility model proposes a sealing cover of a vacuum tank.

Utility model content:

The purpose of the utility model is to overcome the deficiencies of the prior art and provide a sealing cover for a vacuum tank.

In order to solve the above technical problems, the utility model adopts the following technical scheme: the sealing cover of the vacuum tank includes: a cover body and a sealing cover installed on the cover body, and a through hole through the cover body is opened on the cover body, The sealing cover is installed at the through hole, and the sealing cover includes: a body and a columnar plug perpendicular to the body. Adsorbed on the surface of the cover; the columnar plug is arranged perpendicular to the bottom surface of the body, and the end of the columnar plug is provided with a limiting protrusion that restricts the columnar plug from withdrawing from the through hole.

Further, in the above-mentioned technical solution, the columnar plug is provided with an air groove connected to the outside, and an automatically closed vacuum suction port connected with the air groove is provided on the body, through which the vacuum suction port inside the tank body is provided. Gas pumped out.

Furthermore, in the above technical solution, the air groove extends from the bottom of the columnar plug to the main body, and communicates with the automatically-closable vacuum suction port.

After adopting the above technical scheme, the utility model has the following beneficial effects compared with the prior art: the utility model provides a through hole on the cover body, and through a sealing cover with a vacuum suction port, a vacuum pump is used to clean the inside of the tank body. The air is pumped, and the gas is discharged through the air groove and the vacuum suction port; after the inside of the tank is vacuumed, the products packed in the tank can be better preserved, so that it can be kept fresh for a longer period of time and is not easy to deteriorate.

Detailed ways:

Below in conjunction with specific embodiment and accompanying drawing, the utility model is further described.

As shown in Figures 1-4, the sealing cover of the vacuum tank includes: a cover body 2 and a sealing cover 3 installed on the cover body 2, and a through hole 20 penetrating through the cover body 2 is provided on the cover body 2, and the through hole The sealing cover 3 is installed at 20, and the sealing cover 3 includes: a body 31 and a columnar plug 32 perpendicular to the body 31, the columnar plug 32 protrudes from the bottom of the cover body 2 through the through hole 20, and the body 31 Its bottom surface is set in the shape of a suction cup to be adsorbed on the surface of the cover body 2; the columnar plug 32 is arranged perpendicular to the bottom surface of the body 31, and the end of the columnar plug 32 is provided with a limiting protrusion that restricts the withdrawal of the columnar plug 32 from the through hole 20. From 321.

Specifically, the columnar plug 32 is provided with an air groove 33 communicating with the outside, and an automatically closed vacuum suction port 34 communicating with the air groove 33 is provided on the body 31, through which the tank body 1 The gas inside is pumped out, and the gas groove 33 extends from the bottom of the columnar plug 32 to the main body 31 and communicates with the vacuum suction port 34 which can be closed automatically.

The using method of the present utility model is as follows:

The utility model is used in conjunction with the tank body 1, puts food into the tank body 1, covers the lid body 2, and makes the tank body 1 hermetically sealed. Next, pump air through a small air pump, align the pump head with the main body 31, pump air through the main body, the gas is discharged through the air groove, the gas passes through the air groove 33 and the vacuum suction port 34 is flushed and discharged outward under the action of air pressure, After the exhaust is completed, the vacuum suction port 34 is automatically closed to prevent air from entering the inside of the tank body 1 .

Thus, after vacuuming the inside of the tank body 1, the articles in the tube body 1 can be better preserved.

Of course, the above descriptions are only specific embodiments of the utility model, and are not intended to limit the implementation scope of the utility model. Should be included in the utility model patent scope.
