Abstract
The utility model discloses a soft one-way breather valve, which comprises a first plastic membrane, a second plastic membrane and a third plastic membrane. An air inlet is arranged on the first plastic membrane, the periphery of the second plastic membrane is connected onto the first plastic membrane, a movable plastic membrane barrier arranged on the second plastic membrane is capable of closing the air inlet in one way, and the movable plastic membrane barrier is integrated with the second plastic membrane. An air outlet is disposed on the third plastic membrane, the periphery of the third plastic membrane is connected onto the other face of the second plastic membrane, and a breathable elastic sheet disposed between the third plastic membrane and the second plastic membrane is capable of pushing the second plastic membrane to be attached to the first plastic membrane in natural state so as to lead the movable plastic membrane barrier to cut off communication between the air inlet and the air outlet. The soft one-way breather valve is capable of preventing dust materials from blocking ventilation holes, and is low in product price and convenience in market operation.
Description
[technical field]
The utility model relates to soft one-way ventilating valve.
[background technique]
In being used at present the package bag upper air valve of malleation all is the Non-return air valve on the former coffee package, and its shell is a hard, is easy to plastic packaging bag is scratched; And air tight partition wherein is thick and heavy sheet rubber and plays seal action with the capillary tube viscosity of silicone oil, so not only the cost cost high but also in case in to wrap thing be that the dust-like goods just are easy to result in blockage that cause can't exhaust.
[model utility content]
The utility model has overcome the deficiency of above-mentioned technology, provides a kind of dust-like material of can avoiding to stop up the soft one-way ventilating valve that vent, product price are lower, be convenient to the market promotion.
For achieving the above object, the utility model has adopted following technical proposal:
Soft one-way ventilating valve, it includes first plastic diaphragm that sets gradually, second plastic diaphragm, the 3rd plastic diaphragm, on described first plastic diaphragm, be provided with suction port, the periphery of described second plastic diaphragm is connected on first plastic diaphragm, second plastic diaphragm is provided with the movable plastic film that can unidirectionally seal suction port and hinders sheet, this activity plastic film resistance sheet and second plastic diaphragm are one, on described the 3rd plastic diaphragm, be provided with the air outlet, the periphery of the 3rd plastic diaphragm is connected on the another side of second plastic diaphragm, is provided with one and can promotes the ventilative spring sheet that second plastic diaphragm is fitted with first plastic diaphragm and movable plastic film resistance sheet cut-out suction port is communicated with the air outlet between the 3rd plastic diaphragm and second plastic diaphragm under nature.
Described movable plastic film resistance sheet is to have the cut channel that does not seal to form by directly drawing on first plastic diaphragm.
Described ventilative spring sheet is made by sponge.
The shape of described first plastic diaphragm, second plastic diaphragm, the 3rd plastic diaphragm all is circular.
The shape of described ventilative spring sheet also is circular.
Described cut channel is the arc cut channel.
Compared with prior art, the beneficial effects of the utility model are: 1, this product main body is plastic film and ventilation sponge, and their quality softnesses can be avoided in the process of using plastic packaging bag being scratched; 2, the sponge of interior supporter for ventilating, and second plastic diaphragm has certain viscosity in the side to first plastic diaphragm, so just can avoid the dust-like material to stop up vent; So 3, constitute that its product price is low is convenient to the market promotion because this product is plastic film and sponge.
[description of drawings]
Fig. 1 is the structural drawing of movable plastic film resistance sheet of the present utility model when sealing suction port;
Fig. 2 is the structural drawing of movable plastic film resistance sheet of the present utility model when opening;
Fig. 3 is the planimetric map of second plastic diaphragm of the present utility model.
[embodiment]
Be described in further detail below in conjunction with accompanying drawing and mode of execution of the present utility model:
Referring to Fig. 1-3, the utility model is soft one-way ventilating valve, include first plastic diaphragm 1 that sets gradually, second plastic diaphragm 2, the 3rd plastic diaphragm 3, on described first plastic diaphragm 1, be provided with suction port 11, the periphery of described second plastic diaphragm 2 is connected on first plastic diaphragm 1, second plastic diaphragm 2 is provided with the movable plastic film that can unidirectionally seal suction port 11 and hinders sheet 21, this activity plastic film resistance sheet 21 and second plastic diaphragm 2 are one, described the 3rd plastic diaphragm 3 is provided with air outlet 31, the periphery of the 3rd plastic diaphragm 3 is connected on the another side of second plastic diaphragm 2, be provided with one and can promote second plastic diaphragm 2 fit with first plastic diaphragm 1 and make movable plastic film resistance sheet 21 cut off the ventilative spring sheet 4 that suction ports 11 are communicated with air outlet 31 under nature between the 3rd plastic diaphragm 3 and second plastic diaphragm 2, this ventilative spring sheet 4 is made by sponge.
During use, mode or other the mode of first plastic diaphragm 1 by heat seal is fixed in the package bag that needs exhaust, makes suction port 11 aim at the gas port in the package bags.When the gas of package bag during greater than the air pressure in the external world, positive pressure gas in the package bag will be opened to air outlet 31 directions from gas port discharge and promotion activity plastic film resistance sheet 21, positive pressure gas will just be passed through 31 discharges from the air outlet of ventilative spring sheet 4 through suction port 11 like this, by this product the positive pressure gas in the package bag is discharged.When the package bag internal air pressure is less than or equal to extraneous air pressure, because ventilative spring sheet 4 is in reset mode under nature, ventilative spring sheet 4 can promote second plastic diaphragm 2 and first plastic diaphragm 1 is fitted and make movable plastic film hinder sheet 21, make movable plastic film resistance sheet 21 cover suction port 11, Wai Jie gas just can not enter in the package bag by this product like this.
Described movable plastic film resistance sheet 21 is to have the cut channel 22 of the arc that does not seal to form by directly drawing on first plastic diaphragm 1.
The shape of described first plastic diaphragm 1, second plastic diaphragm 2, the 3rd plastic diaphragm 3 all is circular.The shape of described ventilative spring sheet 4 also is circular.
Effect for the unidirectional exhaust that improves this product, second plastic diaphragm, 2 selected films have certain viscosity in the one side towards first plastic diaphragm 1, are bonded together to guarantee suction port 11 second plastic diaphragm 2 and first plastic diaphragm 1 under the situation of non-exhaust.
