Technical Problem to be Solved · The aforementioned one-way exhaust valve has the following problems The point ‧ . h 敝 敝 1 _ _ _ _ _ _ _ 造 造 造 造 造 造 造 造 造 造 造 造 造 造 造 造 造 造 造 造 造 造 造 造 造 造 造 造 造 造 造 造 造The joints are interlocked between each other. During the process of inhaling, the upper cover is separated from the valve seat and the upper cover is closed on the valve seat after the suction is completed. This implementation is easy to cause the cover to be lost, and the assembly is dismantled. The procedure of the upper cover is extremely inconvenient in operation. 3. The above-mentioned upper cover is fastened to each other and protrudes on the sealed bag. Therefore, during the stacking, handling or storage of the sealed bag, the upper cover is easily pushed and squeezed. 4. When the sealed bag is filled with air and the upper cover is closed, if the sealed bag is squeezed or impacted by external force, an instantaneous pressurization will occur in the bag, when the pressure is greater than the sealing strength between the upper cover and the valve seat. Time, It will force the upper cover to pop up and cause an accident. 5. The diaphragm with soft film inside the valve seat will force the diaphragm to shift when the upper cover is impacted or stressed by external force, because there is no buffer or positioning device between the upper cover and the diaphragm. Therefore, if the diaphragm is too strong, it will shift and the sealing effect will be weakened. 6. The diaphragms shown in Patent Documents 1 to 5 are all made of silicone or rubber, which are susceptible to weathering and cold shrinkage and other factors causing stiffness or deterioration. In particular, in the cold zone environment, a small amount of shrinkage deformation is likely to occur, resulting in insufficient pore sealing and air backflow, resulting in a poor effect of the airtight 6 M286202. • The air valve shown in Patent Documents 4 and 5 has no upper cover structure, although The structure of the gas valve is simplified, but as long as the diaphragm for closing the air hole is slightly deformed or damaged, the gas 'hole sealing is incomplete and the air is returned, and the plastic valve has a plastic service life and the diaphragm is affected.

(First Embodiment) As shown in Fig. 1, an exploded perspective view of a first embodiment of the present invention, in which a non-one-way air valve 1G is provided in a valve seat 并 and an annular cam ring Sexual contact_film 2,-pressing device 3 on _ 2 is composed of a valve cover 4 screwed onto the valve seat 1 and pressing the pressing device, and the combined appearance is as shown in Fig. 2 As shown in FIG. 3 and FIG. 4, the valve seat 丨 is a flat plate having an opening at one end and a flat plate having a radial extension and being combined with the sealing bag, and the center of the bottom plate of the other end of the gutter 12 is provided with a positioning hole. 13. A plurality of air holes 14 and a convex ring 17 of the ring dog are arranged around the periphery, and the outer edge of the valve groove 12 on the flat plate η has an external thread 18, and the top end of the external thread 18 has a ring 19 having an outer diameter larger than the external thread 18. The retaining ring is provided with a plurality of notches 191 (four as shown in the figure). Secondly, the bottom of the valve slot 12 is provided with a plurality of deflectors for vertical anti-disclosure which are radially distributed at the center of the positioning holes 13. 15' further, the positioning hole 13 has an annular convex ring 16 under the bottom of the positioning hole 13 for connecting with the baffle 15, the convexity of the convexity of the ring 11 M286202 is smaller than that of the deflector 15 degree. The structure of the above _ 2 is as shown in FIG. 5 and FIG. 6 , and the diaphragm 2 is in the valve groove 12 of the braided rubber material, and the bottom portion of the bottom body has a projection bolt 21 in the position of the bottom hole 13 of the bottom of the human body 12 (refer to the figure) 9). The pressing device 3 is a spring, which is an elastic device with one end facing the valve cover 4 and the other end facing the diaphragm 2 and corresponding to the annular convex ring 17 of the bottom plate of the valve groove 12 (refer to Fig. 9). The structure of the valve cover 4 is as shown in FIG. 7 and FIG. 8. The top surface of the valve cover 4 has a plurality of exhaust holes 41, and the bottom edge of the inner wall is provided with a plurality of radially protruding claws 42, and the positions of the claws 42 are The predetermined notch 191 of the stop ring 19 is oppositely disposed. When the hook 42 is guided along the notch 191, the hook 42 can be screwed with the external thread, so the side cover 4 is rotated. A spiral lifting action can be produced on the valve seat 1, and the claw 42 can be guided by the notch 191 to guide the material to be led out of the π 191. As shown in Fig. 9, the figure shows the connection _ of the combination of the valve seat diaphragm 2, the pressurizing device 3 and the cover 4, and the diaphragm 2 is inside the -12, and is inserted into the valve groove by the bottom projection 21! 2 Positioning in the positioning hole 13 of the bottom plate, the bottom surface of the diaphragm 2 is in linear contact with the annular convex ring π on the bottom plate; the job 4 is screwed with the external thread 18 on the hard rod i, when the valve cover 4 and the valve seat! After the screwing, the remaining 3 is the ship and is displayed between the bonnet 4 and the diaphragm 2. Since the vest 5 has a lion ring 43 for the pressurizing device, the ugly 2 top and the lion lion ring 22 sets. Into the county 3, so the bonnet 4, the pressurizing device 3 and the diaphragm 2 can produce an extremely stable positioning effect. The lower end of the pressing device 3 is the ring M286202 convex ring corresponding to the bottom plate of the gutter 12 When the pressure is applied to the diaphragm 2, the diaphragm 2 and the annular collar 17 are caused to have an extremely airtight effect. As shown in FIG. 10, before the valve cover 4 is to be combined with the valve seat 1, the valve cover 4 must be positively engaged by the hooks 42 and the notches 191 of the retaining ring 19, and can be axially guided due to the convexity of the claws 42. The depth of the exit is greater than the radial depth of the notch 191 of the stop ring 19, so that the hook 42 can no longer be reversely retracted by the notch 191 after being introduced from the π 191, even if the cover 4 is unscrewing, it will not be separated from the _ ,. - Come, you can avoid the occurrence of the bonnet 4 after the bonnet 4 is detached, and the detachment or the reverse rotation of the pedestal 4 will control the tightness of the pressurizing device 3, thereby making the diaphragm 2 and the sipe 12 The air or deflation function is generated between the bottom plates, which will be further explained in the following drawings. As shown in the figure, the one-way _ 1〇 is used on the sealed bag 1 ,, and the sealed bag 1GG can be used as a health care 骑. As shown in FIG. 12, the combination of the one-way air valve 10 and the sealed bag 100 is based on the top surface of the flat plate 11 of the valve seat 1 and the bottom surface of the bag 1〇1 on the sealed bag 100 by a high-frequency fusion technology. Only the outer thread 18 of the upper portion of the valve seat 1 and the valve cover 4 screwed to the external thread 18 are exposed outside the sealing bag i (10). Since the outer cover 4 is not detached from the valve seat 1 as described above, even if the outer cover 4 receives an external force The impact will not fall off, and it, 'Fig. 12 also reveals that when the one-way air valve 1 is to be subjected to Wei operation, the valve cover 4 should be loosened in the reverse direction, so that the gap between the valve cover 4 and the _ 2 is increased. Large, so that the adding and pressing device 3 can be used to reduce the application of the _ 2, and the pre-extracting step is completed to perform the suction operation. As shown in Fig. 13, the suction pipe (10) of the suction device (10) is sleeved at 13 M286202: the cover (4) of the cover is wrapped in the fine (4) fine suction (4) inhalation operation; thereby sealing The bag (10)_gas is sucked out and the bag is smashed; Γ;;^ / will be lifted together with 2 coffees, so that the diaphragm 2 is no longer in contact with the bottom of the valve groove 12 = the convex ring 17, when the line inside the bag is under strong suction It is sucked out by the suction pipe 103 through the vent d, the hole 14 and the vent hole 41 of the 4, until the vacuum is (4) 2 . When the aspirating operation is performed as described above, the lion embossed egg under the slaving hole 13 of the radiation plate 15 under the valve seat 1 can effectively block the sealed bag and the lower bag 102 and be taken to prevent the air hole 14 from being blocked and inhaled. The homework can be successful. As shown in Fig. 14, after the inhalation is completed, the suction pipe ι〇ι can be removed from the 阙 cover*, and the diaphragm 2 is quickly attached to the ice bulge due to the action of the damper force and the (four) in the sealed bag (10). The one-way anti-reverse action is generated on the %17. In other words, the diaphragm 2 can be automatically attached to the annular convex ring 1 when the suction operation is stopped, so that the outside air cannot enter the sealed bag 100. As shown in Fig. 15, after completing the foregoing steps, the operator then tightens the valve cover 4 downward to shorten the distance between the valve cover 4 and the diaphragm 2, so that the pressure of the pressing device 3 after being pressurized is increased. The diaphragm 2 is subjected to a greater pressure to make the sealing effect between the _ 2 and the annular collar 17 stronger to effectively prevent air backflow. (Second Embodiment) As shown in Fig. 16 and Fig. 17, respectively, a perspective exploded view and a combined view of a second embodiment of the present invention, the present embodiment and the first embodiment are singularly placed under pressure M286202.

The device 5 is not a spring, but a rigid transparent plastic pressure seat configured as a short column tube 50 having an outer diameter slightly smaller than the inner diameter of the valve groove 12, and extending radially at the upper end edge of the short column tube 5〇- The lobe lip 51 is placed against the valve cover 4, and the lower end is placed against the diaphragm 2, and the lower & opening is further provided for the annular convex ring μ of the top surface of the diaphragm 2 to be introduced (refer to FIG. π), and the short column is 50 is also provided with a wing-shaped hollow closing groove 52; secondly, a cross-shaped reinforcing reinforcement 53 is arranged in the lower end opening of the short column body 50, and a downwardly convex circular pressure is arranged under the bottom surface of the reinforcing rib 5-3. Ring %, the pressure ring % is matched with the upper and lower protruding top ring 131 i on the edge of the hole of the squatting hole 13 , and the pressure ring and the top ring 131 can clamp up and down the central portion of the diaphragm 2 The effect (as revealed in Figure μ) is such that the central region of the diaphragm 2 does not bulge upwards or downwards, but remains flat at all times. In addition, the _ 12 externally placed with the notch i9i corresponding to the screw groove 181 'to replace the aforementioned first - actual 郷 _ 欢 18 18, the ΐ ΐ 8 ΐ is oblique and the upper and lower ends are horizontal and both ends are stalled At the end, the claw 42 of the bottom edge of the closed cover 4 can be rotated and raised in the screw groove 181, but when it is turned to the upper and lower ends of the screw groove 18, the 'month b rotates horizontally' until the end is stopped; The hook 42 of the cover* can be easily introduced by the notch 191 but is not easily led out by the notch 191. As shown in Fig. 18, when the combination of the one-way air valve 1〇 is completed, the lip 5i of the transparent pressurizing device $ is interposed between the bonnet hole 44 and the valve seat retaining ring 19, at which time the bottom edge of the pressurizing device $ is The diaphragm 2 is attached, and the diaphragm 2 is closed on the lion ring mouth, so the one-way air pump 10 is in the state of _, unable to intake or exhaust. As shown in Fig. 19, when the job 4 is loosened for suction, the diaphragm 2 and the domain device 5 are lifted together with more than 2 faces, so that the diaphragm 2 is no longer in contact with the ring Φ embossing 17 on the bottom plate of the valve groove 12. ' & bag (10) air under strong suction, the air hole 14 of the M286202 is sucked by the suction ruler 103 through the slot 52 of the Garlic device 5, the vent hole 41 of the valve cover 4, until The bag is almost vacuum. Moreover, after the bonnet 4 is loosened and lowered, it is with the valve seat! There is a large spacing between the ring lg, but the spacing is β, the short column of the device 5 and the lip μ are closed, so the suction pipe (10) inhales the air in the air seal & 1GG Quickly pass through the one-way air valve, and will not inhale the perforation 44 of the job 4 when inhaling. Next, in Fig. 16, it is also revealed that the surface of the retaining ring 19 of the valve seat 标示 is marked with a different color mark 192, 193, respectively, if the mark 192 is green and the mark 193 is red 'the two redundant numbers are kept at a certain angle (such as 9〇.), this angle is also the maximum angle of rotation of the bonnet 4 on the sley\, and a perforation 44 is added to the top surface of the alpha bonnet 4 with the two markings 192, 193. When the one-way valve combination is completed (as shown in Fig. 7), only the transparent lip 51 is interposed between the perforation 44 and the top surface of the stop ring 19 (refer to Fig. 8). Since the lip 51 is transparent, the user observes the perforation 44 with the naked eye. At the time, the color of the mark 192 or 193 can be observed through the transparent lip 51, which can facilitate the screw tightness of the green valve cover 4 and the sley 1, for example, when the green mark 192 is displayed in the through hole 44, the surface is not unidirectional _ 10 In the closed state (that is, when 4 is screwed, unable to intake or exhaust j), the red § 193 indicates that the one-way air valve is in the open state (ie, the valve cover 4 is not screwed). The gas or the exhaust gas is used, so that the opening and closing state of the one-way air valve 10 can be judged by visual observation. This is an easy way to judge the use state of the one-way air valve to remind the user to pay attention.
