Description

An improved vacuum tank

Technical field:

The utility model relates to the technical field of storage tanks, in particular to an improved 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, the sealed cans that have appeared in the market one after another, as long as the structure of the sealed cans on the market is 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. However, the sealed can with this 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 improves the sealing tank in the prior art, and proposes an improved vacuum tank.

Utility model content:

The purpose of the utility model is to overcome the deficiencies of the prior art and provide an improved vacuum tank.

In order to solve the above technical problems, the utility model adopts the following technical solutions: an improved vacuum tank, comprising: a tank body and a cover installed on the tank body, the edge of the cover body is sealed and connected with the opening of the tank body, A through hole communicating with the inside of the tank is opened on the cover, and a sealing cover is installed at the through hole, the sealing cover includes: a body and a columnar plug perpendicular to the body, the columnar plug extends out of the cover through the through hole At the bottom, there is an air groove connected to the outside in the cylindrical plug, and an automatically closed vacuum suction port connected to the air groove is provided on the body, through which the gas inside the tank is drawn out.

Further, in the above technical solution, the cover body includes: an inner cover and an outer cover wrapped around the inner cover, and a foldable flange is arranged on the outer cover in contact with the opening of the tank body. Clings tightly to the inner wall of the tank to achieve a tight seal.

Furthermore, in the above technical solution, the through hole is provided on the inner cover.

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, an improved vacuum tank includes: a tank body 1 and a cover body 2 installed on the tank body, the edge of the cover body 2 is sealed with the opening of the tank body 1, and the cover body A through hole 20 communicating with the interior of the tank body 1 is opened on the body 2, and a sealing cover 3 is installed at the through hole 20. The sealing cover 3 includes: a body 31 and a columnar plug 32 perpendicular to the body 31, and the columnar plug 32 passes through The through hole 20 protrudes from the bottom of the cover body 2, and an air groove 33 communicating with the outside is provided in the cylindrical plug 32, and an automatically closed vacuum suction port 34 communicating with the air groove 33 is provided on the body 31, through which the vacuum suction port 34 The gas inside the tank body 1 is extracted.

Specifically, the opening of the tank body 1 is set as a flat mouth, and the cover body 2 includes: an inner cover 21 and an outer cover 22 wrapped outside the inner cover 21, and the outer cover 22 is in contact with the opening of the tank body 1 A foldable flange 221 is provided at the center, and the through hole 20 is provided on the inner cover 21. When in use, the cover body 2 is fastened on the tank body 1, and the flange 221 on the cover body 2 is due to the inner wall of the tank body. A frictional force is generated between them, and under the action of the frictional force, the flange 221 rolls up and clings to the inner wall of the tank body 1 to realize sealing.

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

First, put the food into the tank body, cover the lid body 2, and turn over the flange 221 on the lid body 2 to seal the tank body 1. 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.
