[0030] 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 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.

[0031] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0032] The preferred implementation of the utility model is now further described in conjunction with the accompanying drawings. Figure 1 , Figure 2 and Figure 7As shown, the press-to-fill and deflate air valve comprises a fitting surface 100, in which a first air duct 130 is arranged, one end of the first air duct 130 is connected to a flat elastic air bag 200, and one end of the first air duct 130 away from the elastic air bag 200 is connected to an air valve 300, and the air valve 300 comprises a second air duct 310 for connecting an object to be inflated and the outside, and both ends of the second air duct 310 are respectively covered with a first one-way air sheet 320 and a second one-way air sheet 330, and a deflation piece 400 is arranged between the first one-way air sheet 320 and the second one-way air sheet 330.

[0033] In the application scenario of the present embodiment, the fitting surface 100 is integrated with the exterior of the object to be inflated. When the elastic inflatable bag 200 is inflated, the air in the elastic inflatable bag 200 passes through the first air channel 130 and the second air channel 310 in sequence, and then flows into the interior of the object from the first one-way vent sheet 320. After the air in the elastic inflatable bag 200 flows out, negative pressure is generated in the elastic inflatable bag 200, and the external air enters the second air channel 310 from the second one-way vent sheet 330, and then flows into the elastic inflatable bag 200 through the first air channel 130. By repeating this operation, the air in the elastic inflatable bag 200 can be inflated into the object. When deflation is required, the deflation component 400 is controlled to open the first one-way vent sheet 320 and the second one-way vent sheet at the same time. 330, the gas in the object flows from the first one-way vent sheet 320 into the second vent channel 310, and then flows to the outside from the second one-way vent sheet 330, thereby achieving deflation. Compared with the prior art, the elastic inflatable bag 200 and the air valve 300 of the present application are integrated through the first vent channel 130, and the whole is attached to the object to be inflated, so the air tightness is good after the overall installation. In addition, the inflation and air intake process of the present application only passes through the first vent channel 130 and the second vent channel 310, and there is no need to open another vent channel on the elastic inflatable bag 200, thereby improving the overall air tightness of the product. At the same time, the deflation piece 400 can be used to open the first one-way vent sheet 320 and the second one-way vent sheet 330, without the need for complex workpieces such as springs, and the cost is low and the structure is simple.

[0034] On the basis of the above embodiments, Figures 2 to 4 As shown, the fitting surface 100 includes a first fitting body 110 and a second fitting body 120 which are tightly fitted to each other. In some embodiments, after the embodiment is installed, the first fitting body 110 is arranged on the outside of the object to be inflated, such as the outside of a bag, and the second fitting body 120 is arranged on the inside of the object to be inflated, such as the inside of a bag.

[0035] On the basis of the above embodiments, Figures 2 to 4As shown, the first fitting body 110 is provided with a first opening portion 210 that bulges outward, and the outside mentioned here is the outside of the object that needs to be evacuated, and the second fitting body 120 is provided with a second opening portion 220 that bulges inward, and the inside mentioned here is the inside of the object that needs to be evacuated. When the first fitting body 110 and the second fitting body 120 are closely attached to each other, the elastic inflatable bag 200 is formed by the first opening portion 210 and the second opening portion 220 being closely attached to each other. In some embodiments, the shapes of the first opening portion 210 and the second opening portion 220 are both hemispherical, so when the first opening portion 210 and the second opening portion 220 are closely attached to each other, the elastic inflatable bag 200 forms a roughly spherical shape as a whole.

[0036] On the basis of the above embodiments, Figures 2 to 4 As shown, a through groove 121 is opened on the second fitting body 120, and when the first fitting body 110 and the second fitting body 120 are in close contact with each other, the first air channel 130 is formed by the first fitting body 110 covering the through groove 121. In this way, after the entire fitting surface 100 is installed in place, the first air channel 130 is entirely buried inside the object that needs to be inflated. Compared with the traditional structure, firstly, no external air pipe is required, which saves the overall number of components. Secondly, burying the first air channel 130 inside can prevent external objects from damaging the first air channel 130, thereby causing the entire function to fail.

[0037] On the basis of the above embodiments, Figures 2 to 4 As shown, the second vent 310 is used to connect the inside and outside of the object to be inflated, the first one-way vent sheet 320 is arranged between the second vent 310 and the inside of the object to be inflated, and the second one-way vent sheet 330 is arranged between the second vent 310 and the outside of the object to be inflated. The first one-way vent sheet 320 and the second one-way vent sheet 330 both include a fixing portion 321 and a sealing portion 322. The sealing portion 322 is an elastic sheet. When the air pressures on both sides of the sealing portion 322 are inconsistent, the sealing portion 322 will bend and deform toward the side with weaker pressure. The fixing portion 321 is arranged in the middle of the sealing portion 322, and the fixing portion 321 is used to be combined and fixed with the second vent 310.

[0038] On the basis of the above embodiments, Figures 2 to 5As shown, a connecting vent 311 for connecting and fixing the first one-way vent sheet 320 and the second one-way vent sheet 330 is provided in the second air duct 310. The connecting vent 311 has a sheet-like structure and completely covers the two ends of the second air duct 310. The connecting vent 311 includes a connecting hole 3111 arranged in the middle and a plurality of vent holes 3112 arranged around the connecting hole 3111. When the first one-way vent sheet 320 and the second one-way vent sheet 330 are connected to the two ends of the second air duct 310, the fixing portion 321 is inserted into the connecting hole 3111 to fix the first one-way vent sheet 320 and the second one-way vent sheet 330 to the two ends of the second air duct 310, and the sealing portion 322 covers the vent holes 3112.

[0039] Specifically, combined Figures 2 to 5 ,besides Figure 7 As shown, the sealing portion 322 of the first one-way ventilation sheet 320 covers the side of the connecting vent 311 away from the second air duct 310, so that when the elastic inflatable bag 200 is pressed, the air in the elastic inflatable bag 200 passes through the first air duct 130 and the second air duct 310 in sequence, causing the sealing portion 322 of the first one-way ventilation sheet 320 to deform to the side away from the second air duct 310 and no longer cover the vent hole 3112, so that the air can flow into the object through the second air duct 310 to complete inflation.

[0040] The sealing portion 322 of the second one-way ventilation sheet 330 covers the side of the connecting vent 311 close to the second air channel 310, so that when negative pressure is generated in the elastic inflatable bag 200, the external air causes the sealing portion 322 of the second one-way ventilation sheet 330 to deform toward the side close to the second air channel 310 and no longer covers the vent hole 3112, thereby allowing the external air to flow into the elastic inflatable bag 200 after passing through the second air channel 310 and the first air channel 130 in turn. In this way, the user can continuously press the elastic pressing portion to allow the air outside the second one-way ventilation sheet 330 to continuously flow from the first one-way ventilation sheet 320 into the object through the second air channel 310, thereby forming continuous inflation.

[0041] On the basis of the above embodiments, Figure 2 , Figure 6 and Figure 7As shown, the deflation member 400 includes an eccentric rod 420 that is arranged in an axial direction away from the fixing portion 321. Preferably, the eccentric rod 420 is vertically arranged between the fixing portion 321, and a deflation rod 430 is arranged at a section of the eccentric rod 420 away from the fixing portion 321. The position of the deflation rod 430 is opposite to the sealing portion 322 of the first one-way vent sheet 320, so that when the fixing portion 321 of the second one-way vent sheet 330 is pressed down, the sealing portion 322 of the second one-way vent sheet 330 is driven to 2 is separated from the vent hole 3112, and the eccentric rod 420 and the deflation rod 430 are driven to move as a whole. Since the deflation rod 430 is located opposite to the sealing portion 322 of the first one-way vent sheet 320, the deflation rod 430 will poke the sealing portion 322 of the first one-way vent sheet 320 to deform and thus separate from the vent hole 3112 when moving, so that the two ends of the second vent 310 are connected, and the air in the object can flow to the outside through the second vent 310, thereby achieving the deflation function.

[0042] On the basis of the above embodiments, Figure 2 , Figure 6 and Figure 7 As shown, it should be noted that the function of the eccentric rod 420 is to deflect the direction between the fixing portion 321 and the deflation rod 430, so that the deflation rod 430 will not touch the fixing portion 321 of the first one-way vent sheet 320 during the movement, and will only touch the sealing portion 322 of the first one-way vent sheet 320. Therefore, after the deflation is completed, the fixing portion 321 of the second one-way vent sheet 330 can be pulled up to disengage the deflation rod 430 from the sealing portion 322 of the first one-way vent sheet 320, so that the sealing portion 322 of the first one-way vent sheet 320 can restore its deformation and re-seal on one side of the vent hole 3112, thereby making the present application completely free of the need for spring parts and can fully realize inflation and deflation.

[0043] In some embodiments, in combination Figure 2 , Figure 6 and Figure 7 As shown, an end cap 3221 is provided at one end of the fixing portion 321 of the second one-way vent sheet 330 away from the eccentric rod 420 , and the end cap 3221 can facilitate the user to press or pull up the second one-way vent sheet 330 .

[0044] The above exemplary embodiments are detailed, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is limited by the appended claims rather than the above description, so it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
