detailed description:

Referring to Figures 1, 2, and 3, the present embodiment includes a valve body 1 and a compressible air bag 4 (which may also be a self-expanding elastic airbag). The valve body 1 is an injection molded part having an air inlet. 2 and two one-way air outlets 3. The air bag 4 is a compressible air bag which is inhaled or discharged by repeatedly stretching and compressing the air bag 4. Gp, the outside air is sucked into the airbag 4 by the air inlet 2, and then discharged by the one-way air outlet 3 to enter the product to be inflated.

A flange 12 is formed on the main body 11 of the valve body 1, and the flange 12 is provided with an air hole 121 penetrating therethrough. The edge of the flange 12 is provided with a flat plate 122, and an adhesive layer 123 is provided on the flat plate 122. A mouth portion 14 for connecting to a deflation cover 13 is formed at an upper end of the flange 12, A connecting portion 15 for connecting the airbag 4 is formed at the lower end of the flange 12. A venting cover 13 connected to the mouth 14 is sealed to the upper port of the air hole 121, that is, when the deflation cover 13 is mounted on the mouth portion 14, the deflation cover 13 just defines the vent hole formed in the flange 12. 121 sealed. The specific structure is as follows: The deflation cover 13 includes a cover body 131 and a sealing rubber ring 132. The lid body 131 is annular and its inner side surface is formed as an internal thread. The sealing rubber ring 132 is fixedly disposed on the lower end surface of the cover body 131. The mouth portion 14 is provided with an external thread, and the cover body 131 is screwed to the mouth portion 14. When the cover body 131 is in the tightened state, the sealing rubber ring 132 is tightly pressed against the upper surface of the flange 12, and is just sealed. Covering the upper port of the air hole 121; conversely, when the cover body 131 is in the released state, the sealing rubber ring 132 will leave the upper surface of the flange 12, thereby opening the air hole 121.

The air inlet 2 of the valve body 1 described above is disposed in the main body 11, and a flap 21 is disposed at the port of the air inlet 2. The flap 21 is generally made of a pliable material. The flap 21 covers the lower port surface of the air inlet 2, and the flap 21 has a surplus space for moving up and down. When the airflow enters inwardly from the air inlet 2, the flexible flap can be opened under the external atmospheric pressure to allow the airflow to enter smoothly. However, the internal airflow cannot open the flap 21 from the inside to the outside, because the internal air pressure will tightly press the flap 21 against the port of the air inlet 2, and the air inlet 2 is sealed, so that the airflow cannot be caused by the airflow. The holes are discharged.

The air outlet 3 described above is provided on the main body 11 below the flange 12, and a flap 31 is also provided at the port of the air outlet 3. The flap 31 is also made of a pliable material. The flap 31 covers the outer port surface of the air outlet 3, so that when the airbag is compressed and the gas in the airbag 4 is discharged outward, since the port of the air inlet 2 is covered by the flap, the airflow cannot be caused by the internal pressure. The air inlet 2 is exhausted. At that time, the airflow will blow open on the outer port of the air outlet 3 The flap 31 allows air to enter the inflatable product.

The intake port 2 and the air outlet 3 realize the function of the check valve by the above structure. The air bag 4 communicates with the air inlet 2 and the air outlet 3 through the internal passage of the valve body 1.

The connecting portion 15 formed at the lower end of the flange 12 is used for connecting the airbag 4, and the opening of the airbag 4 is sleeved on the connecting portion 15, and the concave and convex portions formed by the opening of the connecting portion 15 and the airbag 4 are formed to be engaged to maintain the two. The stability between the two. Of course, it is also possible to join the two together by welding or bonding.

Referring to Fig. 4, this is another embodiment of the present invention. In the present embodiment, a mouth cover 141 is provided at the port of the mouth portion 14 of the valve body 1 in comparison with the previous embodiment. The mouth cover 141 is connected to the mouth portion 14. When the inflation is completed, the mouth cover 141 can be placed on the upper port of the mouth portion 14 (ie, the air inlet 2 is sealed), so that the airflow in the inflated product can be prevented from penetrating. , to ensure the sealing of the entire inflatable product, while the mouth cover 141 can also play the role of decorative appearance.

Referring to Fig. 5, which is a specific use of the present invention, the inflated product used is an inflated pillow 5.

See Figures 6, 7, and 8, which show the operation of the air intake, exhaust, and exhaust of the airbag 4, respectively. During the installation process, the present invention is first placed in the interior of the inflatable pillow 5, and the rubberized layer 123 on the flange 12 is spliced together with the inflatable pillow 5 by ultrasonic welding (or other bonding means), and the airbag is simultaneously The tail portion 41 is fixed to the edge of the inflatable pillow 5. Care should be taken during the splicing process that the air vents 121 on the flange 12 cannot be shielded. When the inflatable pillow 5 needs to be inflated, the user holds the valve body 1 in one hand, and the other hand holds the tail portion 41 of the airbag 4 through the surface of the inflatable pillow 5, and then starts to repeatedly stretch and compress the airbag 4. When the airbag 4 is stretched (see Figure 6), the airflow is from the air inlet 2 Enter, the airflow opens the flexible flap 21, allowing the airflow to smoothly enter the airbag 4. When the airbag 4 is compressed (see Fig. 7), when the air in the airbag 4 is compressed outward, the port of the air inlet 2 is covered by the flap 21 by the internal pressure, and the airflow cannot be discharged by the air inlet 2. At the same time, the airflow will blow the flap 31 on the outer port of the air outlet 3, so that the airflow enters the outer inflatable pillow 5, so that the inflatable pillow 5 can be repeatedly inflated. When the inflation is completed, the mouth cover 141 can be placed on the upper port of the mouth portion 14 to prevent the airflow in the inflated product from penetrating, thereby ensuring the tightness of the entire inflatable product.

When the air in the inflatable pillow 5 needs to be squeezed out, the air flow described above cannot be discharged from the air inlet 2. The present invention achieves deflation by the following process. See Figure 8. First, loosen the deflation cover 13, and raise the deflation cover 13 by a certain distance. At this time, the sealing rubber ring 132 on the deflation cover 13 is separated from the upper surface of the flange 12. Thus, the port on the air hole 121 loses its seal. Since the air vent 121 communicates with the internal cavity of the inflatable pillow 5, the air vent 121 can discharge the gas in the inflatable pillow 5. If the inflatable pillow 5 is squeezed during deflation, the speed of deflation can be accelerated. At the same time, due to the one-way setting of the air outlet 3, when the air-filled pillow 5 is squeezed, the airflow in the air-filled pillow 5 does not enter the airbag 4 from the air outlet 3. When the gas in the inflatable pillow 5 is completely discharged, the deflation cap can be tightened.

As shown in Fig. 9, the third example is compared with the first embodiment. The main difference is that the air outlet 3 is closed and leads to the air nozzle 42. Others have no essential difference. The product of this embodiment is suitable for use as a separate inflator, and it is convenient to inflate inflatable products such as inflatable toys and inflatable pillows.

The inflator of the present invention can be combined with an aerated product, has a simple structure, and is convenient to use. In any case, the user can charge the inflated product as needed. Gas. The present invention can be used on a variety of different inflatable items, such as swim rings, inflatable pillows, air mattresses, inflatable toys, and the like.

Of course, the above description is merely a specific example of the present invention, and is not intended to limit the scope of the present invention. For example, the inflatable pillow in the above embodiment may be replaced by an inflatable bed, an inflatable doll or the like. Therefore, equivalent changes or modifications made to the structures, features, and principles of the present invention should be included in the scope of the present invention.
