The entire contents of the above-identified application are hereby incorporated by reference.
The present disclosure relates to the technical field of domestic utensils, and in particular relates to a cushioning airbag device.
In daily life, shoulder strap backpacks, waist bags, shoulder bags, arm bags, and other bag products are often used in households, automobiles, medical purposes, sport activities. The traditional bag products often only focus on the functionality such as loading capacities. In the process of designing or purchasing backpacks, much attention is placed on the number of bags in the backpacks, how much it can hold, or whether it looks good, but little attention is place on the comfort of users when using the backpacks. When the backpack is being used, weight is generally concentrated on the shoulders, waist, neck or arms of the user. However, during use, motions will produce slight vibrations, and the straps of the backpack will produce impact and friction on the contact parts. Especially when people exercise vigorously, the above-described collision force and friction force will produce quite powerful negative effects. When the backpack carries a heavy load or when the user has been carrying the backpack for a long time, local blood circulation of the user may not be smooth due to long-term pressure in these parts, thereby causing pain. In addition, the contact areas may become tightly sealed, thereby making the use to sweat and unable to effectively dissipate heat, causing great discomfort and may even affect skin health, increasing higher health risks to the user. Therefore, airbag cushions with cushioning effects are very popular. This type of airbag cushions includes a plurality of interconnected airbags, which need to be inflated by an inflation pump.

One end of the one-way air inlet component 6, namely a first end, is attached to an inner wall of the first airbag 2 and the first airway 3 by a high-frequency voltage, such that the first end of the one-way air inlet component 6 is always open. The other end of the one-way air inlet component 6, namely a second end, and the middle portion of the one-way air inlet component 6 are located inside the second airbag 4.
In first embodiment, the upper piece 61 and the lower piece 62 are both plastic flat pieces, when the upper piece 61 and the lower piece 62 of the middle portion and the second end of the one-way air inlet component 6 contact each other, the upper piece 61 and the lower piece 62 can have the absorbing effect, thus playing a role in sealing the airway. When using the seat cushion 200, the first airbag 2 is squeezed or pressed, the elastic member 21 inside the first airbag 2 is pressed, the gas in the first airbag 2 flows into the middle portion of the one-way air inlet component 6 through the first end of the opened one-way air inlet component 6. At this time, the upper piece 61 and the lower piece 62 of the middle portion of the one-way air inlet component 6, which are in contact with each other, are separated and opened to form a channel under the pressure of the gas. Furthermore, at this time, the second end of the one-way air inlet component 6 is also propped open by the pressure of the gas, such that the gas flows into the second airbag 4 from the channel and the second end of the one-way air inlet component 6. Then, the air flows into the plurality of airbags 205 through the plurality of air channels 203, such that the air fills the whole seat cushion 200. When the squeeze or pression is released, the first airbag 2 is released, under the elastic resetting effect of the elastic member 21, the first airbag 2 is ejected and reset, and at this time, the upper piece 61 and the lower piece 62 at the middle portion and the second end of the one-way air inlet component 6 are in contact with each other, which closes the entrance of the channel. Furthermore, the second end of the one-way air inlet component 6 is also in a closed state, so as to prevent the gas of the second airbag 4 from flowing backwards to the first airbag 2, thereby achieving one-way intake and effectively preventing air leakage.
In one-way air inlet component 6 may be a structure of a one-way air inlet component 60 as shown in
IThe one-way air inlet component 6 may be a structure of a one-way air inlet component 60 shown in
After long-term use, the aging of the upper piece 61 and the lower piece 62 at the anti-leakage portion 69, for example, oil leakage occurred in plastic materials which is used to form the upper piece 61 and the lower piece 62, causes the upper piece 61 and the lower piece 62 to be completely separated and cannot be attracted to each other, thereby resulting in air leakage. In the one-way air inlet component 60 according to the eighth embodiment, even if the upper piece 61 and the lower piece 62 at the anti-leakage portion 69 age, because the fixing portion 691 is provided, the upper piece 61 and the lower piece 62 do not completely separate from each other, thereby effectively preventing a separation phenomenon caused by aging of the upper piece 61 and the lower piece 62, and further ensuring prevention of air leakage.
