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 The food such as product, dry fruit, as shown in Figure 2-5 comprising the top of tank body 3, the tank body 3 is equipped with opening 30, passes through the opening 30 Milk powder is packed into tank body 3.It is detachable in the opening 30 to cover the portable vaccum gland bonnet for having above-described embodiment.

In one embodiment, the top of the tank body 3 is equipped with the protruding ring 31 for outwardly protruding and surrounding the opening 30, The vaccum gland bonnet 1 further includes first sleeve 21, and the upper layer lid 12 and lower layer's lid 11 are fixed on the first sleeve 21 To block the first sleeve 21 on inner wall；The outside of the first sleeve 21 is fixed with second sleeve 22, the first sleeve Slot 20 is formed between 21 and second sleeve 22, when the vaccum gland bonnet 1 is sealed in the opening 30, the protruding ring 31 are inserted into the slot 20.

As shown in figure 4, when protruding ring 31 is inserted into the slot 20, first sleeve 21, protruding ring 31 and second sleeve 22 form three-layer sealed structure, to enhance the leakproofness of vaccum gland bonnet 1.

Further, the inner sidewall of the opening 30 is equipped with the snap ring 32 of protrusion, and the lower end of the first sleeve 21 is fixed There is the sealing ring 23 abutted with the snap ring 32, sealing ring 23 will further enhance leakproofness.

In one embodiment, there is the first notch 33 on the protruding ring 31, have and institute in the second sleeve 22 Stating corresponding second notch of the first notch 33 can be convenient by the gap position and started vaccum gland bonnet, to open tank Body 3.

In one embodiment, articulation piece 111 is fixed on the vaccum gland bonnet 1, the vaccum gland bonnet 1 passes through The articulation piece 111 is hingedly fixed on the lateral wall of the tank body 3, and vaccum gland bonnet 1 can be rotated relative to articulated position, from And it covers onto tank body 3, or separated with tank body 3.Hinged hinged structure on this tank body has been that prior art use is common Technological means, therefore, articulation piece 111 completely can use existing articulated structure, this will not be repeated here.

The above content is combine specific embodiment further detailed description of the utility model, and it cannot be said that The specific implementation of the utility model is only limited to these instructions.For the utility model person of an ordinary skill in the technical field For, without departing from the concept of the premise utility, a number of simple deductions or replacements can also be made.
