Utility model content
This utility model will solve the problems, such as above-mentioned prior art, provides a kind of vacuum carrying into outgassing nonreturn valve
Bag, simple to operate, good airproof performance, structure is simple.
This utility model solves the technical scheme of its technical problem employing：This vacuum bag carrying into outgassing nonreturn valve,
Including bag, bag is provided with sealing strip, and bag is provided with breather check valve and outgassing nonreturn valve；Breather check valve is included even
Lead to the air inlet pipe on bag, in air inlet pipe, be provided with air inlet taper sealed core, the tip of air inlet taper sealed core outwardly, inlet cone
The inner left half of shape sealed core is fixed on air inlet inside pipe wall, and the right half of air inlet taper sealed core is close to air inlet inside pipe wall,
It is plugged with inlet seal plug outside air inlet pipe；Outgassing nonreturn valve includes connecting the escape pipe on bag, is provided with out gas coning in escape pipe
Shape sealed core, inwardly, the left half of cone seal core outer end of giving vent to anger is fixed on inside pipe wall of giving vent to anger at the tip of cone seal core of giving vent to anger,
The right half of cone seal core outer end of giving vent to anger is close to inside pipe wall of giving vent to anger.It is connected to breather check valve on bag in this structure
And outgassing nonreturn valve, easy to use, adopt the sealed core of pyramidal structure in check valve, structure is simple, make easily, and
Can by air inlet pipe and escape pipe do relatively thin, take up room little, and the sealed core of pyramidal structure be outside under the effect of the pressure
Open, there is extraordinary sealing effectiveness.
In order to perfect further, outside escape pipe, it is cased with closure of giving vent to anger.So strengthen the sealing of escape pipe.
Perfect further, the interior part of air inlet taper sealed core is hollow, and in air inlet taper sealed core, extreme direction is provided with plug
Enter the ball of hollow parts, the inwall of air inlet pipe is provided with the block of projection.The hollow parts of inlet cone shape sealed core filled in by ball,
Further enhance sealing effectiveness.
Perfect further, the outer portion of cone seal core of giving vent to anger is hollow, and the outer extreme direction of cone seal core of giving vent to anger is provided with plug
Enter the spin of gap, the inwall of escape pipe is provided with the rib of projection.Spin fills in the hollow parts of cone seal core of giving vent to anger,
Further enhance sealing effectiveness.
This utility model has the advantages that：Vacuum bag of the present utility model adopts breather check valve and outgassing nonreturn valve,
The structure of breather check valve and outgassing nonreturn valve is relatively simple, therefore its volume can be made thin little, reduction takes up room, and
Through multi-sealed, good sealing effect, be conducive to being widely popularized.
