This will cause the venting holes to hide tightly, and the effect of vacuum preservation cannot be achieved with the slowness of the coffee. SUMMARY OF THE INVENTION The main object of the present invention is to provide a product that is mounted on a bag body to prevent the contents of the bag from sticking to the surface of the flange, so that the inside of the bag body does not have a long vacuum to affect the contents. A vacuum one-way exhaust valve that preserves freshness. "b, 'Working from the above can be known' for the above purpose, a vacuum one-way exhaust is assembled in the - bag body, including - bottom cover, - cymbal and - top cover, wherein the bottom cover and the bag Attachment H, the outer wall of the wire is provided with a flange, the inside of the flange is provided with a venting hole, and the outer ring of the flange is provided with a limiting ring, and the inner circumference of the limiting ring forms a current working room. The accommodating space is provided with a gas chamber, and the film is slaved in the accommodating space, and the flange is sealed to the _ hole, which is said to be at least Γ Γ, and the upper cover is located The outer wall of the wire has a ring body (4), such that a ring chamber is formed inside the ring body, and the upper cover wall is a rainbow-exhaust hole, and the exhaust hole is in communication with the chamber, and the upper cover will The film clips are merged and sealed. / /, when the bag body gas is removed, the center of the hair film will be convex outward, and the opening of the L air hole will be removed. * The gas can be ventilated into the air chamber, and the film hole is guided into the chamber. Finally, it is released from the reduced hole of the upper cover, and the powdery content can be gathered with the gas (10) to avoid adhesion to the surface of the flange, so that the adhesive of the vent opening is not "5V". The effect is that the inside of the bag body can be ensured to be vacuumed for a long time to preserve the freshness of the contents. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT The detailed description and technical description of the present invention will be further described, but it should be understood that these embodiments are for illustrative purposes only. The limit. The vacuum one-way exhaust valve of the present invention, which is not shown in FIG. 1 to FIG. 3, is assembled in a bag body a, and includes: a bottom cover 10, a stone eve film 2 〇, and an upper cover. do not. The bottom cover 10 - the side is the outer wall n, the outer peripheral surface of the outer wall u is adhered to the inner surface of the bag body a, and the outer wall U is axially provided with a flange 12' a venting hole 13 , a limiting ring 14 is disposed on the outer side of the flange 12 , so that the inner circumference of the limiting ring 14 forms a circular accommodating space 15 , and the inner circumference of the accommodating space 15 is recessed inwardly. An air chamber 16 is lower than an outer end surface of the flange η. The outer circumference of the limit ί ί 设 抵 抵 抵 抵 抵 抵 抵 抵 抵 抵 抵 抵 抵 抵 抵 抵 抵 抵 抵 抵a ring groove 18. The stone eve film 2G is a circular flexible softness county installed in the accommodating space 15 ' 'the outer circumference is just set by the limit ring 14 , the piece 2 〇 affixed The convexity=12 and the opening of the vent hole 13 is sealed, and the stone film (9) is axially disposed at least one of the money 21'. The air hole 21 is disposed on the outer circumference of the stone film 20 (four vents in this embodiment) The upper cover 30 is located on the outer wall 11 of the bottom cover 10. The upper cover 30 is located on the outer wall 11 of the bottom cover 10. The inner wall of the bottom cover 30 is provided with a protruding ring body 31. The object 31 0 forms a chamber 32. The π side is convexly disposed in the axial direction, and the sealing ring 33 is disposed around the outer side of the limiting ring 14. The sealing portion 33 is sleeved with the annular groove 18 of the upper cover 3 to form a tight fit. The outer cover 201040084 wall δ is at least one venting hole 34, and the venting opening 34 is in communication with the chamber 32, and is a tapered hole having an inner side aperture larger than the outer diameter hole, and the ring body 31 is matched with the annular hole 31. The accommodating space 15 of the bottom cover 10 is sandwiched and positioned; and the outer periphery of the upper cover 30 is provided with an annular portion 35, and a hollow suction pump 40 is sleeved with the upper cover 30. The inner wall of the air suction cylinder 40 is provided with a concave edge 41. The locking portion 35 is engaged with the concave edge 41, and an end surface of the air suction cylinder 4 adjacent to the upper cover 3 is just abutted by the resisting ring 17.借此 In this way, the present invention is applied to a bag body a containing a coffee bean, and the air canister 40 can be engaged with the upper cover 30 by using the pumping cylinder 40 as shown in FIG. 3, and the gas in the bag body a is extracted. The Shixi film 20 will be deformed so that the center is convex and is separated from the vent hole 13 of the bottom cover 1 opening. The gas in the bag body a can enter the air chamber 16 through the vent hole 13, and then The air hole 21 of the eve film 20 enters the chamber 32, and finally is drawn away from the vent hole % of the upper cover 3〇, and gradually forms a vacuum. The air ejector 4 is removed, and the crepe film 2 紧 is tight due to the pressure difference. The opening of the vent hole 13 is adhered to form a sealed state in the bag body a, as shown in FIG. 4 to extend the freshness of the contents stored in the bag body a. It is important that the coffee beans contained in the bag body a remain powdery coffee powder, and the coffee powder is pumped out together with the suction cylinder 40, and the present invention is used to avoid powdery curry powder. The contents are attached to the surface of the 夕 胶片 film 2 ', so that the opening 1 of the vent hole 13 that can not be tightly sealed for a long time can gradually get out of the opening of the vent hole 13 over time, resulting in the bag body a being unable to maintain. The vacuum state of the seal further affects the preservation freshness of the contents. Therefore, the present invention is provided with the flange 12 in the center of the bottom cover 1'. The outer circumference of the flange 12 is a recessed air chamber 16 space, and can accommodate the powdery inner 6 201040084 The grain 'avoids the adhesion to the surface of the flange 12, so that the stone film 2 is tightly sealed. The opening of the vent hole 13 ensures that the inside of the bag body a is in a vacuum state, and the contents are preserved for a long time. Freshness. Referring to FIG. 5 again, the present invention can also be assembled on a container, and a button 22 is disposed at the outer center of the film 20. The button 22 is passed through the upper cover 3, and the pump 40 is taken out. The gas in the container b is evacuated, and the inside of the container b is vacuumed to preserve the freshness of the contents of the container b. When the button 22 is pulled outward, the outside air can enter the 0 container b. As shown in FIG. 6, the present invention is reversely mounted on the container b, and the outside gas can be filled into the container b by the 5 pure air holes 13, so that the container b is filled with gas, and the available-bumps are released. The gas in the container b can be vented by being inserted into the vent hole 13 and pressed against the chopped film to disengage the flange 12'. Therefore, the design structure of the present invention, whether it is a gas which is pumped or filled with powder, can be deposited in the gas chamber 16, and does not affect the gas tightness of the vent film 13 which seals the vent hole 13. However, the above description is only a preferred embodiment of the present invention, and when it is not possible to limit the application of the present day, that is, the average change and the series of the transcripts of the genus Within the scope of the invention patent.
