Detailed Description

The invention will be further described with reference to the accompanying drawings and specific embodiments to assist understanding of the invention.

As shown in fig. 1 and 2, the present embodiment provides a negative pressure self-sustaining vacuum tank, which includes an upper cover 1, a tank body 2 and a bottom cover 13, wherein the upper cover 1 is fastened to the top of the tank body 2, a glue plug hole 3 is formed in the upper cover 1, a rubber plug 4 is disposed in the glue plug hole 3, and a rubber ring 5 is sleeved on the upper cover 1. The rubber plug 4, the rubber plug hole 3 and the rubber ring 5 are mutually matched with the contact surface of the tank body 2, and a closed space is formed above the tank body 2. The upper cover 1 of the present embodiment is made of an airtight material, preferably transparent plastic or metal, and the rubber plug 4 and the rubber ring 5 are preferably made of silica gel or rubber material with moderate elasticity.

The tank body 2 is internally provided with a partition plate 6, the tank body 1 is divided into an upper section and a lower section by the partition plate 6, the upper part of the partition plate 6 forms an accommodating space for storing articles, the lower section is used for placing a vacuumizing device, and the partition plate 6 is provided with a vent hole 7 which is used as a passage for air suction.

The vacuum pumping device of this embodiment includes air pump 8, three-way valve 9, power 10 and control circuit 11, and three-way valve 9 one end is connected with air vent 7, and one end is connected with air pump 8, and negative pressure switch 12 is installed to the other end, and air pump 8, power 10 and negative pressure switch 12 are connected with control circuit 11.

The air pump 8 of the present embodiment has a check function or the air pump is connected with a check valve.

The control circuit 11 of this embodiment can adopt various forms as long as it can control the start and stop of the air pump according to the vacuum degree fed back by the negative pressure switch, as shown in fig. 3, it is a circuit block diagram of one of them, and this control circuit includes a main control module, and the main control module periphery is connected with touch button, negative pressure switch interface, air pump drive circuit, load current detection circuit, battery protection circuit, charge management circuit and electric quantity and work pilot lamp and buzzer.

This embodiment provides a vacuum tank is held by oneself to negative pressure, when using, places the food that needs keep fresh or the damp-proof article of needs in the accommodation space of jar internal space bar top, puts into the plug downthehole and makes its adaptation with the plug, and the rubber ring overlaps on the periphery of upper cover and presses jar body oral area and makes its adaptation, forms airtight space in the jar body.

The control circuit controls the starting of the air pump, the air pump pumps out air in the accommodating space at the upper section of the tank body through the air holes, and the external air pressure presses the upper cover tightly; when the negative pressure switch detects the upper limit value of the negative pressure, the power is cut off, the air pump stops working, and the air pump or the check valve with the check function prevents the external air from flowing back to the tank body, so that the inside of the tank body is vacuumized.

After a period of time, the vacuum degree is gradually reduced, the negative pressure switch is connected with the power supply after detecting the negative pressure lower limit value, and the air pump works repeatedly, so that the vacuum degree in the tank body is always maintained between the upper limit value and the lower limit value of the negative pressure switch.

When the articles in the tank body need to be taken out, the rubber plug is pulled, so that the external air enters the tank body, the vacuum state disappears, the upper cover can be separated from the tank body, and the articles can be taken out.

Compared with the prior art, the vacuum tank of the application is always kept in a vacuum state in the power supply maintaining period, so that the freshness keeping period of food in the container can be prolonged by several times, and the requirements of people are greatly met; the structure is simple, the manufacture is convenient, and the production cost can be greatly reduced; simple to use, one key starts the vacuum, and one pulls out and releases the vacuum.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention.
