The first airbag 2 , the second airbag 4 , and several second airbags 4 are connected together through an airway 3 .

In the above-mentioned implementation, there may be one or more airbags. For example, the first airbag 2 and the second airbag 4 shown in FIGS. And the second air bag 4 can synthesize an air bag. As the basic constituent unit of the cushioning airbag cushion, the airbag can have one or several airbags. When there are several airbags, the several airbags are connected together through the air passage, but the air inlet is arranged on the first airbag. And at least the first airbag is provided with an elastic body, and the air outlet is arranged behind the last airbag, so as to meet the needs of inflation and deflation, and meet people's needs for length, width, shape and other aspects.

In the actual airbag cushion, the airbag cushion has a single-sided or double-sided convex airbag. Therefore, there must be a sponge in the first airbag to help the airbag cushion to lift up. Therefore, pressing is exhalation, and pushing is inhalation. There are two valves around the airbag cushion, an inlet valve and an outlet valve.

The airbag cushion can be made by plane pressing, and the material used for the single-sided and double-sided convex airbags is mainly TPU, elastic cloth, TPR glue, or PVC. Such as TPU over TPR glue, composite elastic cloth, as the material of the upper surface. The other is TPU glued with TPR glue, pasted with elastic cloth, TPR glue passed again, and then a layer of TPU glued.

If the underlying surface does not need airbags, use TPU or TPR glue to bond non-elastic materials or fabrics.

The advantage of using TPU and fabric is that it is elastic. A massage cushion is inflated to a saturation by the atmosphere of the air pump, and the airbag cushion will not grow or become higher all the time, and will be pulled by the fabric, such as only TPU without fabric. The airbag cushion can get bigger and bigger, get tired or even burst.

An air inlet and an air outlet are provided in the airbag.

Usually, the air inlet 1 has a one-way air inlet valve; the air outlet 5 is a one-way air outlet valve to ensure the one-way flow of gas, thereby producing a specific cushioning effect. For the air inlet of the above embodiment, a one-way air intake valve is usually used, and there are several implementation methods, which are briefly described below: As shown in Figures 7 to 8, it is the first implementation of the one-way air intake valve , in this mode, the air intake valve includes an air intake piece 11, a ball 12 and a holding piece 13, the air intake piece 11 has a cavity 111, an air inlet 114 is opened on one side wall of the cavity 111, and the other The sidewall defines an air outlet hole 112 , and the air inlet member 11 has an inner edge 113 protruding inward, and the inner edge 113 is used to engage the holding member 13 .

The front end of the top holder 13 has a funnel-shaped opening 133, which can accommodate the ball 12, and the bottom of the funnel-shaped opening 133 is connected with a through hole 134, which is used for air intake; the diameter of the bottom of the funnel-shaped opening 133 is less than The diameter of the ball 12 is such that the ball 12 can roll in the opening without leaving the opening; the front end 131 of the holding member 13 is in the shape of a truncated cone, and the rear portion 132 is in the shape of a reduced diameter.

The holding part 13 is sleeved in the cavity 111 of the air intake part 11, and the inner edge 112 is just stuck to the diameter-reducing part, so that the front end 131 is locked in the cavity 111, so that when the air is inhaled, the gas passes through Hole 134 enters, Pass through the opening 133 and the cavity 111, and enter the first airbag 2 through the air outlet 112; however, when the gas wants to flow out from the opening 133, under the action of the gas, the ball 12 will be stuck in the opening 133, closing the opening 133 , so that the gas cannot flow out from the opening 133 through the through hole 134, thereby forming a unidirectional flow effect.

The one-way intake valve is to block the air port of access by ball 12 . The air inlet part 11 that puts ball 12 has a bell mouth, and through hole 134 is a circle, and air outlet 112 is inline, so ball 12 can be blocked on the one hand, can't be blocked on the other hand. So when you press the airbag cushion, you can only inhale but not out.

As shown in Figure 9, Figure 10, and Figure 11, it is the second implementation of the one-way intake valve. In this mode, the intake valve includes an intake terminal 21, a locking member 22, and a plug 23. And the cover body 24, this implementation method can not only realize one-way air intake, but also can control the air discharge, so as to be used when needed.

The catch part 222 is sleeved on the support frame 215, so that the support frame 215 supports the catch member 22 (the end 223 is located below the support frame 215, and the head 221 is located above the support frame 215). A trigger 22 controls the intake and discharge of air.

Normally, the locking member 22 is flexible, and the plug 23 is rigid, and the plug 23 is sleeved on the head 221, so that it is convenient to press the plug 23 by hand.

When inhaling air, align the air pump with the air inlet 214, and the air pump will push against the locking member 22, thereby pushing the support frame 215, so that the air outlet 216 is opened, so as to inflate. After the inflation is completed, block it with the cover body 24 The air inlet 214 achieves the effect of sealing.

When releasing air, firstly the cover body 24 is opened, the plug 23 is pressed, and the plug pushes the locking part 22 downwards, thereby opening the air outlet 216 to achieve the effect of deflation. At this time, the intake valve can not only realize the function of intake air, but also have the function of deflation.

As shown in Figures 12 to 15, it is the third implementation of the one-way intake valve. In this implementation, the intake valve includes an intake terminal 31, a spring 32, and a plug 33. This implementation can not only realize One-way air intake can also be controlled to release air for use when needed.

Specifically, the air inlet terminal 31 has an air inlet part 311, a bearing platform 312, a boss 313 and an air outlet part 314, wherein the main body of the bearing platform 312 is a hollow cylindrical structure, and the middle part of the bearing platform 312 has a protruding boss 313. The table 313 is convenient for setting and fixing the one-way air intake valve. The upper end of the bearing table 312 is the air inlet portion 311 , and the lower end is the air outlet portion 314 .

The inner middle of the carrying platform 312 has a card edge 315 protruding inward, and the card edge 315 is used to support the plug 33 .

One end of the plug 33 has a protruding portion 331 , and below the protruding portion 331 is a diameter-reducing portion 332 .

The spring 32 is sleeved on the diameter-reducing portion 332 .

When installing, first put the spring 32 on the diameter-reducing portion 332, and then pass the bottom 333 of the plug 33 through the hole 316 in the middle of the card edge 315 of the intake terminal 31, so that the spring 32 is located between the card edge 315 and the protrusion 331 In this way, when inflated, the gas will break through the blockage of the bottom 333 and enter the first air bag or the second air bag from the hole 316 to inflate; after inflated, the bottom 333 will rise under the action of the spring 32 to block the hole 316 (bottom The diameter of the portion 333 is greater than the inner diameter of the hole 316), so as to achieve the sealing effect.

When deflating, press the protruding part 331 of the plug 33, the protruding part 331 pushes the spring 32 downward, and at the same time the bottom 333 also moves downward, thereby opening the hole 316, so that the air inlet part 311 and the air outlet part 314 can be connected to achieve deflation Effect.

For the one-way air outlet valve, it can be arranged at the air passage or the air outlet.

In order to simplify the structural design, the air outlet is designed with two plastic sheets connected around the periphery. The two plastic sheets can be attached together to play a sealing role. However, the inner side of the plastic sheet is arranged on the first airbag or the second airbag. The inner wall of the airbag, so that the gas can be discharged in one direction.

Since the upper sheet 61 and the lower sheet 62 are both plastic sheets 6, they are flat as a whole, can have an adsorption effect when they are in contact with each other, and can be naturally attached together, so they can form the effect of sealing the air passage.

Therefore, when installed in the airway, the plastic sheet is slightly opened in the direction of air outlet, so that when the air is out, the gas can enter between the upper sheet 61 and the lower sheet 62 along the wall of the first airbag or the second airbag to exhaust, thereby To achieve the effect of deflation. But when the gas will enter the first airbag or the second airbag from between the upper sheet 61 and the lower sheet 62, because the upper sheet 61 and the lower sheet 62 are bonded, there is no opening, so the plastic sheet cannot be inflated. It has the function of one-way air outlet.

The plastic sheet can also be used in the air outlet as a channel for the air outlet.

In a word, the present invention provides cushioning for the stress-bearing parts through the way of air intake on one side and air outlet on the other, which conforms to the principle of force, and can generate buffering effect through other flows, which has the effect of reducing people's pressure and provides a new buffering method .

And combined with the design of the one-way intake valve, it can well control the direction of the airflow, which is convenient In the realization of the buffer effect.
