Abstract

The utility model relates to a vacuum seal container, comprising a container body and a container cover. A one-way valve is arranged on the container cover. A cylinder barrel is arranged in a matching mode on the one-way valve. The utility model is characterized in that air in the container can be pumped; outside air can be prevented from entering the inner cavity of the container with the combination use of the cylinder barrel and the one-way valve. An effect of vacuum seal can be really reached.

Description

A kind of vacuum seal jar

The utility model relates to a kind of vacuum seal jar.

The airtight container of market is of a great variety, but all is to add at the cover place to put device for fastening, gas in the container and outside air is intercepted, to reach sealing purpose.But there are a lot of problems in this hermetically-sealed construction, the one, and tightness is not enough, and air infiltrates in the container as before; Another is that gas is not discharged in the container, does not really reach sealing purpose.

The purpose of this utility model is at above-mentioned deficiency, proposes a kind of vacuum seal jar.

The utility model is made up of tank body, cover, has a check valve, the spool of check valve to place seam through hole on the cover on its cover, and check valve is supporting in addition a cylinder barrel.

Above-mentioned check valve is made up of spool and valve gap, spool one end band guide rod, and valve gap is actively set on the guide rod; The spool other end has boss, and is identical with the seam through hole on the cover.

Above-mentioned cylinder barrel is made up of cylinder body, piston, piston rod, and piston, piston rod place in the cylinder body, can upper and lowerly move; Piston rod bar side is fluted, is provided with deflation hole between piston and piston rod.

Now with reference to the accompanying drawings the utility model is further described:

Accompanying drawing 1 is that the utility model tank body is non-tight status architecture section-drawing;

Accompanying drawing 2 is that the utility model tank body is sealing shape section of structure;

Accompanying drawing 3 is the utility model cylinder barrel section of structures;

Accompanying drawing 4 is that the A-A of accompanying drawing 3 is to section drawing.

As shown in Figure 1, cover 2 places on the tank body 1, and the check valve of being made up of valve gap 3 and spool 4 places the through hole of cover 2, the boss 5 on the spool 4 and the seam through hole 6 separated attitudes of cover 2, and this moment, outside air entered tank inner chamber, and cover 2 can be raised at any time.

Shown in accompanying drawing 2,3, cylinder barrel is seated on the check valve of the cover 2 on the tank body 1, the cylinder body 7 of cylinder barrel is aimed at valve gap 3, spool 4, twitch piston rod 8, gas in the tank body 1 constantly passes through seam through hole 6, the valve gap 3 and spool 4 gap locations of cover 2, by the deflation hole 10 of 8 in piston 9 and piston rod, discharge again along the groove on the piston 8 11; When gas was lower than outside air in the tank body 1, the boss 5 of spool 4 was held, and tightly fills at seam through hole 6 places of cover 2, has cut off tank inner chamber and outside air, and tank inner chamber is negative pressure state, and cover 2 and tank body 1 are muddy to be one, can not raise.If the guide rod of the spool 4 of check valve is upwards carried, the boss 5 of spool 4 separates with the seam through hole 6 of cover 2, and outside air enters tank inner chamber, is accompanying drawing 1 state, and cover 2 can be raised.

Shown in accompanying drawing 3, accompanying drawing 4, cylinder barrel is made up of cylinder body 7, piston rod 8 and piston 9, and piston 9 sides are provided with groove 11, and 9 in piston rod 8 and piston are provided with deflation hole 10.

The utility model modern design, simple in structure can not only be extracted gas in the tank body out, and can be prevented that outside air from entering tank body, really plays vacuum-packed purpose.

Claims

1, a kind of vacuum seal jar comprises tank body 1, cover 2, it is characterized in that on its cover 2 check valve being arranged, and the spool of check valve places seam through hole 6 places on the cover 2, with check valve is supporting a cylinder barrel is arranged.

2, vacuum seal jar according to claim 1 is characterized in that described check valve comprises spool 4 and valve gap 3, and valve gap 3 is actively set on the guide rod of spool 4; Spool 4 other ends have boss 5, and the seam through hole 6 of itself and cover 2 coincide.

3, vacuum seal jar according to claim 1 is characterized in that described cylinder barrel is made up of cylinder body 7, piston rod 8, piston 9, and piston 9, piston rod 8 place in the cylinder body 7, can upper and lowerly move; Piston rod 8 sides are fluted 11, and 8 in piston 9 and piston rod have deflation hole 10.
