Description

A kind of hand pressure air bag of inflation/deflation structure integral type

Technical field

The utility model relates to it is a kind of be specially adapted for elastic fluid with muscle-powered pump, a kind of specifically hand pressure Formula, the air bag that the apparatus that needs are inflated is inflated.

Background technique

Aerated product is product common in daily life, such as swimming life-buoy, air pillow, inflated seat cushion, inflatable toys.It passes Single stomata is only arranged in the inflation type products of system on product, and inflation/deflation passes through this stomata, in order to ensure what is used Reliability, such product, which asks inflation/deflation, certain resistance, is inflated certain difficulty by manually blowing, deflation work Also it is not easy to carry out, and the not standing inflation equipment of the family of user, user can be allowed to feel inconvenient in this way.In order to Overcome this problem, occurs the air bag of some hand pressures in practice, this air bag is mounted on aerated product, it can be right Aerated product is inflated；But often only inflation effect, deflation function generally still need to another on aerated product such air bag Peripheral hardware sets deflation structure.The mode that this air bag and deflation structure are provided separately can make aerated product structure is complicated to change, It is not easy to automation, procedure production, is also easy to raise production cost；In addition charging valve is generally located on air bag body, shadow Pressing feel is rung, and pressing repeatedly can also make valve and the junction of air bag body be easily destroyed.

Utility model content

In order to overcome the air bag of the prior art to only have aerification function, the defect for function of not deflating, the utility model A kind of hand pressure air bag of inflation/deflation structure integral type is provided, inflatable structure and deflation structure are concentrated in air bag, It can simplify aerated product structure, production finished product be effectively reduced, and be easy to use.

The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of hand pressure of inflation/deflation structure integral type Air bag has air bag body, forms hollow capsule room inside air bag body；Air bag body side has an Extendible flake, has inflation on Extendible flake Valve and deflation valve.

It include upper plenum chamber and lower plenum chamber inside the charging valve；It is connected to inside lower plenum chamber and air bag body； There is upper plenum chamber separate layer below upper plenum chamber, upper plenum chamber and lower plenum chamber are separated；It is filled under having below lower plenum chamber Gas chamber separate layer separates the plenum space of lower plenum chamber and aerated product；Upper plenum chamber separate layer and lower plenum chamber separate Respectively there is an inflation air-core hole at layer middle part, and inflating around air-core hole has inflation stomata；There is inflation gaseous core on inflation air-core hole, inflates Gaseous core includes inflation main core, has the first diaphragm seal below inflation main core, is located at around inflation main core above the first diaphragm seal There is the first outwardly projecting portion at place, and upper plenum chamber separate layer or lower plenum chamber separate layer are stuck among the first diaphragm seal and the first outwardly projecting portion, First diaphragm seal can cover all inflation stomatas.

The deflation valve internal includes venting chambers, has venting chambers separate layer below venting chambers, by venting chambers with fill The plenum space of gas product separates；There is a deflation air-core hole in the middle part of venting chambers separate layer, has deflation around deflation air-core hole Stomata；There is deflation gaseous core on deflation air-core hole, deflation gaseous core includes deflation main core, there is the second diaphragm seal below deflation main core, There is the second outwardly projecting portion in top, there is spring around deflation main core, and venting chambers separate layer is stuck between the second diaphragm seal and spring.

There is charging valve closing cock at the charging valve；There is the occlusion of vent valve door seal at the deflation valve.

There is epitaxy part around the air bag body and Extendible flake, epitaxy part is in flat, by air bag body when can facilitate processing It is effectively engaged with aerated product.

Preferably, air bag body includes lower ball sheet body and upper ball sheet body, and correspondingly Extendible flake includes upper Extendible flake and downward Stretch piece；Lower plenum chamber is located at lower extension on piece, the also reserved hole location for placing deflation valve of lower Extendible flake；The external packet of upper plenum chamber Closed structure can be pushed into lower plenum chamber；The external structure of surrounding of venting chambers can be pushed into the reserved hole location of lower Extendible flake；Charging valve Closing cock, the occlusion of vent valve door seal are located on upper Extendible flake.

The utility model has the beneficial effects that charging valve and deflation valve centralized arrangement are not set up directly on gas On the ball wall of utricule, pressing feel can be improved, the feelings for avoiding air bag body and valve junction from destroying because pressing repeatedly Condition occurs, while can simplify the structure of aerated product, keeps aerated product more convenient in assembly, replacement air bag, has Effect reduces production cost.
