Specific embodiment
The utility model is described in further detail below by specific embodiment combination attached drawing.
The utility model embodiment provides a kind of portable vaccum gland bonnet, as shown in Figure 1 comprising upper layer lid 12 and position
Lower layer's lid 11 in 12 lower section of upper layer lid, upper layer lid 12 and lower layer's lid 11 are fixed to one another, and form the main structure of vaccum gland bonnet.
And the upper layer lid 12 and lower layer's lid 11 are enclosed closed seal chamber 10, are all provided on the upper layer lid 12 and lower layer's lid 11
There is perforative through-hole, the through-hole on upper layer lid 12 and lower layer's lid 11 is connected to the seal chamber 10.In the through-hole of lower layer's lid 11
Equipped with the first check valve 13, gas can not be only vented outwards by the first air inlet into seal chamber 10 of check valve 13.On
Second one-way valve 14 is equipped in the through-hole of layer lid 12, the gas in seal chamber 10 can be discharged by second one-way valve 14.
Wherein, 12 elastically deformable of upper layer lid, and there is stronger elastic reset power, it can specifically use the stronger iron plate of toughness
It is made.
When using the vaccum gland bonnet of this implementation, vaccum gland bonnet is fixed on tank body or cabinet, lower layer's lid 11
Towards in tank body or cabinet, upper layer lid 12 is exposed.User's pressable upper layer lid 12, then the seal chamber 10 is extruded, in
The gas in portion is discharged by second one-way valve 14.When the pressing force being applied on upper layer lid 12 disappears, upper layer lid 12 is at itself
The effect of elastic reset power is lower to be resetted, and the air pressure in seal chamber 10 reduces, and the gas of 11 lower section of lower layer's lid passes through the first check valve 13
It enters in seal chamber 10, i.e. the intracorporal gas of tank body or case enters in seal chamber 10, and passes through 14 row of second one-way valve
Out.Upper layer lid 12 is pressed repeatedly, tank body or the intracorporal air of case can be vacuumized.
The Vacuuming structure of this push type eliminates user and mating carrying is needed to take out very without using arriving vacuum pumping pump
The inconvenience of sky pump, use are more convenient.
In one embodiment, as shown in Figure 1, the upper layer lid 12 and the outermost edge of lower layer's lid 11 are bonded admittedly each other
It is scheduled on together, the seal chamber 10 is located at the middle part of upper layer lid 12 and lower layer's lid 11.Further, the middle part of the upper layer lid 12
Form the arc convex outwardly protruded.This arcuate structure provides upward tension, so that the upper layer lid 12 being extruded is more
It is easy to reset, also enhances the durability of product, can prolong its service life.
In one embodiment, portable vaccum gland bonnet further includes first sleeve 21, the upper layer lid 12 and lower layer's lid
11 are fixed on the inner wall of the first sleeve 21, and outer periphery and the first sleeve 21 of upper layer lid 12 and lower layer's lid 11 are fixedly linked
To block the first sleeve 21.The second sleeve 22 of coaxial arrangement is fixed in the outside of the first sleeve 21, described
The slot 20 being inserted into for tank wall is formed between one sleeve 21 and second sleeve 22.This inserting slot construction, is close to sealing cover
In the opening of tank body, to enhance leakproofness.
Wherein, the lower end of the first sleeve 21 is fixed with sealing ring 23, to further enhance leakproofness.
The utility model embodiment also provides a kind of food cans, which can be used for containing milk powder, nutriment, health care
