1 and 2, the air injectable condom 100 includes an endothelial 110 and an outer shell 120.

Endothelial 110 is formed in a hollow cylindrical shape having a predetermined length extending from the opening 110 having a first inner space 114.

Endothelial 110 is formed of an elastic material, preferably a silicon material.

The outer shell 120 is formed outside the endothelial 110 to surround the endothelial 110 from the opening 112 of the endothelial 110 so that the opening 112 is opened, and an air injection space therebetween. It is coupled with endothelial 110 to have 130.

The outer shell 120 is formed of an elastic material, preferably a silicon material.

A plurality of spacers 122 are formed between the outer shell 120 and the inner shell 110 to support the outer shell 120 and the endothelial 110 to be spaced apart from each other so as not to block the air injection space 130.

Unlike the illustrated example, the outer shell 120 and the endothelial 110 may be partially bonded in a point fusion method.

In addition, a ring portion 123 protruding from the inner side and the outer side of the outer shell 120 is formed.

The air injection chamber 130 formed by the outer shell 120 coupled to the outer shell 110 is partitioned into a pumping chamber 131 and a main injection chamber 135 that can form independent air storage chambers.

The pumping chamber 131 is formed along the extending direction of the endothelium 110 from the opening 112 forming portion, the main inlet 132 is formed on one side to suck air from the outside, the main inlet 132 It has a structure having an internal space in which the relay sphere 133 is formed on the other side. The pumping chamber 131 is formed such that the pumping chamber 131 extends outward more than the main injection chamber 135 with respect to the inner shell 110.

The main suction port 132 of the pumping chamber 131 may be formed on the side surface of the outer shell 120 unlike the illustrated position.

The relay port 133 is provided between the main injection chamber 135 and the pumping chamber 131 so as to provide a flow path through which air is flowed between the pumping chamber 131 and the main injection chamber 135. It is formed by the protruding pipe 133 which protrudes a predetermined length in the direction toward the entrance chamber 135. As shown in FIG.

The main suction port 132 of the pumping chamber 131 communicates with the inlet pipe 132a and the inlet pipe 132a which protrude outward from the shell 120, but the extension part 132b protruding inside the pumping chamber 131. It has a structure having.

The inflow pipe 132a is preferably formed to be able to enter the extension part 132b when forcibly pressed inward.

The external opening / closing member 140 supports the stopper 142 and the stopper 142 formed to open and close one end of the main suction port 132 exposed to the outside with respect to the outer shell 120. )

The first thin film valve 150 is installed to be opposite to the end of the main inlet 132 opposite to the stopper 142 in a detachable position from the inner surface of the pumping chamber 131, that is, the extension part 132b, to form the pumping chamber 131. It is formed to open and close the terminal of the main inlet 132 according to the change in the internal pressure according to the change.

The main injection chamber 135 is formed to extend along the extension direction of the endothelium 110 so that the air in the pumping chamber 131 can be introduced through the relay port 133.

The second thin film valve 160 is installed to face the relay port 133 from the inner wall of the main injection chamber 135 to open and close the relay port 133 according to the pressure change of the main injection chamber 135 and the pumping chamber 131. It is formed to be possible.

The air injection type condom of this structure is pressurized by the pumping chamber 131 as shown in FIG. 3 with the stopper 142 separated from the main inlet 132 when the first thin film valve 150 is pumped chamber ( The main inlet 132 is closed from the inside by the pressurization of the air in the 131, and the second thin film valve 160 is retracted and pumped away from the relay 133 by the pressurization of the air in the pumping chamber 131. Air in the chamber 131 is injected into the main injection chamber 135. Then, when the pressing force applied to the pumping chamber 131 is released, as shown in FIG. 4, the air injected into the main injection chamber 135 is discharged into the pumping chamber 131 due to the pressure difference. The thin film valve 160 is moved toward the relay port 133 to close the relay port 133, and the first thin film valve 150 is driven by the suction force generated when the outer shell 120 is expanded by the restoring force of the pumping chamber 131. ) Is separated in a direction away from the main inlet 132, the outside air is introduced into the pumping chamber 131 through the main inlet 132. Therefore, if the process of pressurizing and releasing the pumping chamber 131 is repeated, the desired amount of air may be injected into the main injection chamber 135. In addition, after the appropriate amount of air is injected, the main inlet 132 has a stopper 142 provided to close the discharge of the air in the main injection chamber 135 and the pumping chamber 131 to the outside. After the insertion is closed, the inflow pipe 132a may be processed after being used to enter the outer shell 120. Meanwhile, after use, the membrane valves 150 and 160 may be forcibly operated in a direction separated from the relay port 133 or the main suction port 132 to discharge air.

In this structure, the pumping chamber 131 has a second thin-film valve due to the pressure difference generated in the process of pressing and releasing between the pubic bone and the pubic bone of men and women during the sexual act, in addition to the air injection function into the main injection chamber 135. As the 160 is opened and closed, the outer shell 120 is expanded and contracted by the air amount change in the main injection chamber 135, and the pumping chamber 131 or is expanded and contracted. In particular, the pumping chamber 131 acts to pull the skin around the clitoris during pressing and retraction in the process of the compression and compression between the pubic bone to provide the effect of stimulating around the clitoris and to suppress the departure from the penis during the act. Do it.

Meanwhile, as illustrated in FIG. 5, an external pumper capable of pumping and supplying air through the air inlet tube 210 detachably formed with the main inlet 132 to inject air through the main inlet 132. Of course, the 200 can be used as needed.

According to the air-injected condom according to the present invention as described so far, it is possible to expand to a desired size by air injection, the user can easily inject air even while wearing, the pumping chamber acts in addition to the air injection function Suppresses the escape from the penis during the period.
