The first end surface 115 and the second end surface 117 are disposed opposite to each other, the first end surface 115 faces the outside, and the second end surface 117 faces the airbag of the cushion airbag device 100. The bottom surface 111 and the side walls 113 are fixedly connected to the inner wall of the air inlet 1011 of the cushion airbag device 100 in a sealed manner to prevent air from leaking between the air outlet 11 and the air inlet 1011 of the cushion airbag device 100. The arcuate side wall 113 mates with the air inlet 1011 of the cushion airbag device 100. The first end surface 115 is concavely provided with a mounting groove 1151, and the mounting groove 1151 is used for accommodating the elastic member 13 and the fixing member 15. A vent hole 1171 is opened from the bottom surface of the mounting groove 1151 through the second end surface 117, and the vent hole 1171 communicates with the mounting groove 1151 and the first bladder 1021 of the cushion bladder device 100 for supplying the external air into the first bladder 1021 of the cushion bladder device 100.

The fixing member 15 has a cylindrical shape and includes a side wall 151, and a first end surface 153 and a second end surface 155 connected to the side wall 151. The first end face 153 and the second end face 155 are disposed opposite to each other, the first end face 153 facing the air outlet 11, and the second end face 155 facing the outside. The first end surface 153 is concavely provided with a receiving groove 1531 for receiving the elastic member 13. A through hole 1551 is formed through the second end surface 155 from the bottom surface of the accommodating groove 1531, and the through hole 1551 communicates with the accommodating groove 1531. The receiving groove 1531 has a cylindrical shape so as to receive the elastic member 13. In the present embodiment, the diameter of the accommodating groove 1531 is larger than the diameter of the through hole 1551. The through hole 1551 is exposed to the outside or connected to an inflator (not shown), and outside air is introduced into the first bladder 1021 of the cushion bladder device 100 through the through hole 1551. Since the diameter of the accommodating groove 1531 is larger than the diameter of the sponge 131, when the sponge 131 is accommodated in the accommodating groove 1531, the air passage 16 is formed between the sponge 131 and the inner wall of the accommodating groove 1531. The through hole 1551 and the vent hole 1171 are switched between the communicating state and the non-communicating state by the blocking piece 133.

When the elastic body is present in the first bladder 1021 of the cushion bladder device 100, when the first bladder 1021 of the cushion bladder device 100 is pressed in a compressed state, the sponge 131 moves toward the second end surface 117 of the air outlet member 11 in the accommodating groove 1531 by the air pressure, the barrier sheet 133 releases the through hole 1551, and at this time, the air enters the first bladder 1021 of the cushion bladder device 100 via the through hole 1551, the airway path 16, the plurality of hole portions of the sponge 131, and the vent hole 1171, thereby inflating the plurality of bladders 102; when the first bladder 1021 of the cushion bladder apparatus 100 is released and is changed from the compressed state to the released state, the sponge 131 moves toward the first end surface 115 of the air outlet member 11 in the receiving groove 1531 by the pressure difference between the outside and the inside of the first bladder 1021 of the cushion bladder apparatus 100, and the blocking piece 133 seals the through hole 1551 of the fixing member 15 to prevent the air in the bladder from leaking through the through hole 1551, thereby achieving the effect of preventing the air leakage by the unidirectional air intake.

Or when the first airbag 1021 of the cushion airbag device 100 is inflated by the inflator with or without the sponge, the inflator is connected to the through hole 1551, and when the inflator supplies air to the unidirectional air intake valve 10, the sponge 131 moves toward the second end surface 117 of the air outlet member 11 in the accommodating groove 1531 due to the air pressure, and the blocking piece 133 releases the through hole 1551, and at this time, the air enters the first airbag 1021 of the cushion airbag device 100 through the through hole 1551, the air passage 16, the plurality of hole portions of the sponge 131, and the ventilation hole 1171, thereby inflating the plurality of airbags 102. After the inflation is completed, the sponge 131 moves toward the first end surface 115 of the air outlet member 11 in the receiving groove 1531 by the pressure difference between the outside and the inside of the first bladder 1021 of the cushion air bag device 100, and the blocking piece 133 seals the through hole 1551 of the fixing member 15 to prevent the air in the bladder from leaking through the through hole 1551, thereby achieving the effect of preventing the air leakage by the unidirectional air intake.

Compared with the prior art, the buffer air bag assembly provided by the utility model has the advantages that the situation of preventing air leakage is realized through the unidirectional air inlet valve with a compact structure, so that the air leakage of the buffer air bag device is effectively prevented, frequent air inflation is not needed, and the buffer air bag assembly is convenient to use.

The cushion airbag device 100 may be manufactured by planar lamination, and the materials used for the airbags with single-sided protrusions and double-sided protrusions are mainly TPU, elastic cloth, TPR glue, thermosol, or PVC. If TPU passes through TPR glue, the TPU is attached to the elastic cloth to be used as the material of the upper pad surface. The other is that TPU is coated with TPR glue, elastic cloth is attached, the TPR glue is coated once, and then a layer of TPU is attached. The underlying surface, if an air bag is not needed, is laminated with a material or cloth that is not elastic, either with TPU or with TPU over TPR glue. The advantage of using TPU and cloth is elasticity. A massage cushion is inflated to a saturation level by the inflation of the air pump, and the air bag cushion is not increased or heightened all the time and can be pulled by cloth, if only TPU has no cloth. The larger the balloon cushion can be, the more fatigued or even burst.

In summary, the present utility model can be used on all cushioning airbag cushions, such as shoulder straps, home cushions, waist cushions, mattresses, medical mattresses, car seat belts, insoles, motorcycle cushions, bicycle cushions, mouse cushions, hemorrhoid cushions, knee pads, helmet cushions, bullet-proof vest cushions, and the like.
