Description

Technical Field

[0001] The utility model relates to the field of inflation devices, in particular to a press inflation device. Background Art

[0002] At present, there are many inflatable products on the market, such as inflatable mattresses, which are relatively large inflatable products. However, with the advancement of the times, some small products that need to be inflated have emerged, such as car headrests, lumbar U-shaped pillows or waist belts. The parts of these products that fit the human body are equipped with hollow cavities, which are filled with air. Their function is to reduce shock or make wearing more comfortable. When inflating and deflation of these products, traditional inflation and deflation valves are usually not used.

[0003] Existing inflation devices usually use two one-way air guides to block the air inlet and outlet. The air guides are usually made of elastic soft rubber material. However, after long-term use, the elasticity of the soft rubber material will deteriorate, thereby losing the sealing effect on the air inlet and outlet when there is no external force. Especially in terms of the air outlet, if the air guide that blocks the air outlet loses its elastic sealing effect, it will directly cause the entire product to become useless.

[0026] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by those skilled in the art in the field of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0027] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0028] The preferred embodiment of the present invention will be further described with reference to the accompanying drawings. Figure 1 and Figure 2 As shown, a press-inflatable device includes an upper fitting body 10 and a lower fitting body 20, wherein the upper fitting body 10 and the lower fitting body 20 are tightly fitted together, one end of the upper fitting body 10 protrudes outward to form an elastic pressing portion 11, and one end of the lower fitting body 20 is tightly fitted to the bottom of the pressing portion 11 to cooperate with the pressing portion 11 to form an airbag 100, and a groove 21 is opened on the lower fitting body 20. When the upper fitting body 10 and the lower fitting body 20 are fitted together, the groove 21 is in contact with the airbag 100. In order to allow external air to enter and exit the airbag 100, the upper fitting body 10 and the lower fitting body 20 are formed with a one-way ventilation structure 30 at the end away from the airbag 100. The ventilation structure 30 includes an air inlet structure 200 and an air outlet structure 300. The air outlet structure 300 includes an air outlet channel 310. The air outlet channel 310 is formed with an air outlet 320 on the lower fitting body 20. An elastic member 330 is arranged in the air outlet channel 310. The elastic member 330 forms an elastic blockage on one side of the air outlet 320.

[0029] In the implementation state of this application, the elastic member 330 is sealed on one side of the air outlet 320. When the user presses the airbag 100, the air in the airbag 100 enters the ventilation structure 30 through the groove 21, enters from the air outlet 320, thereby pushing the elastic member 330 from the air outlet 320, and then flows out through the air outlet channel 310. However, after the user releases the airbag 100, the elastic member 330 re-blocks the air outlet 320 under the action of elastic force, and the external gas enters the ventilation structure 30 through the air intake structure 200, and then fills the airbag 100 through the groove 21, thereby completing the entire cycle.

[0030] Compared with the existing technology, the present application uses an elastic member 330 to directly seal the air outlet 320, which has better sealing performance. Even if the gas pressure in the airbag 100 is not large, a good sealing effect can be achieved. Therefore, the entire ventilation structure 30 does not require a sealing cover and will not leak, which is more suitable for current consumption trends.

[0031] On the basis of the above embodiment, Figure 2 and Figure 5 As shown, the elastic member 330 includes a first blocking member 331 and a first spring 332. A first supporting portion 340 is provided in the air outlet channel 310. One end of the first spring 332 abuts against the first supporting portion 340, thereby supporting one end of the first spring 332. The other end of the first spring 332 is connected to the first blocking member 331. When air in the airbag 100 enters through the air outlet 320, an external force is applied to the first blocking member 331. The first blocking member 331 moves in the air outlet channel 310 under the action of the external force, thereby compressing and deforming the first spring 332. When the first blocking member 331 leaves the air outlet 320, the air immediately flows out of the air outlet channel 310 to the outside.

[0032] In some embodiments, as Figure 5 As shown, the area of ​​the end face of the first blocking member 331 is smaller than the area of ​​the end face of the air outlet channel 310. In this way, when the first blocking member 331 moves in the air outlet channel 310 under the action of external force, air can flow out to the outside through the gap between the air outlet channel 310 and the first blocking member 331.

[0033] In some embodiments, combined Figure 2 and Figure 5 As shown, a first protrusion 331a is provided on the side of the first blocking member 331 away from the air outlet 320, and the first spring 332 is sleeved on the outside of the first protrusion 331a, so that when the first spring 332 is compressed and deformed by external force, better contact can be formed between it and the first blocking member 331.

[0034] On the basis of the above embodiment, Figure 3 and Figure 5 As shown, the air intake structure 200 includes an air intake channel 210 and a through hole 220, and a plurality of air inlets 230 are distributed around the through hole 220. A second blocking member 240 is arranged between the air inlet 230 and the air outlet 320. The second blocking member 240 is connected to the through hole 220 and forms an elastic blockage on one side of the air inlet 230. When the user releases the airbag 100, the elastic member 330 re-blocks the air outlet 320 under the action of the elastic force, and the external gas pushes the second blocking member 240 away from the air inlet 230 through the air inlet 230, so that it can enter the airbag 100 through the groove 21.

[0035] On the basis of the above embodiment, Figure 3 and Figure 4As shown, the second sealing member 240 includes an elastic sealing portion 241 and a connecting portion 242 arranged in the middle of the elastic sealing portion 241. The elastic sealing portion 241 is made of elastic soft rubber. During assembly, the connecting portion 242 is inserted into the through hole 220, so that the through hole 220 is closed, and then the elastic sealing portion 241 is used to seal the air inlet 230. When external gas passes through the air inlet 230, the connecting portion 242 ensures the connection between the second sealing member 240 and the through hole 220, and then its elastic sealing portion 241 is deformed and pushed away from the air inlet 230, and the external air can enter the airbag 100 through the groove 21.

[0036] In some implementations, such as Figure 5 As shown, the air outlet 320 is arranged on the lower fitting body 20, and the air inlet 230 is arranged on the upper fitting body 10. The air outlet 320 is located directly above the air inlet 230. This ensures that the distances between the air outlet 320 and the air inlet 230 relative to the airbag 100 are the same, thereby further ensuring that the air intake and air output volumes are basically consistent.

[0037] On the basis of the above embodiment, Figure 5 As shown, a second protrusion 243 extends along the side of the second blocking member 240 away from the connecting portion 242, and a second supporting portion 250 is provided in the air inlet channel 210. The second supporting portion 250 is connected to the second blocking member 240 through a second spring 260. In this way, when the present application needs to deflate, the second supporting portion 250 is pressed to compress and deform the second spring 260, causing the second blocking member 240 to move downward as a whole, and the elastic blocking portion 241 is separated from the blockage of the air inlet 230. When the second blocking member 240 moves to a preset distance, since the air outlet 320 is located directly above the air inlet 230, the second protrusion 243 will pass through the air outlet 320 and contact the elastic member 330, thereby causing the elastic member 330 to move, making it unable to block the air outlet 320. In this way, the air on one side of the air outlet 320 can flow out of the air inlet 230 through the ventilation structure 30, thereby completing the entire deflation process.

[0038] The above exemplary embodiments are detailed, and the present invention may be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all changes that come within the meaning and range of equivalents of the claims be included within the present invention.
