As described above, the air tank 110 is a space in which the air that can be breathed by the diver is compressed and stored. The air tank 110 has an internal pressure of about 200 bar Is stored.

A discharge port 111 for discharging air stored in or stored in the air tank 110 is provided at the tip of the air tank 110. The discharge port 111 is provided with an injection amount of air Or an injection valve 112 for adjusting the discharge amount.

Meanwhile, the inflator automatic opening and closing apparatus for a skin scuba according to an embodiment of the present invention includes a buoyancy regulator 120 for injecting air stored in the air tank 110 to raise the diver to the water surface in water.

At this time, the buoyancy regulator 120 functions as a buoyant body that is inflated by the injected air to raise the diver to the water surface.

The inflator automatic opening and closing apparatus for a skin scuba according to an embodiment of the present invention includes an air inlet valve 112 connected to the air outlet 110 of the air tank 110, 120 for automatically injecting the inflator 130 into the apparatus.

Hereinafter, the inflator 130 will be described in detail with reference to FIGS. 1 to 3. FIG.

The inflator 130 is installed between the discharge port 111 of the air tank 110 and the buoyancy regulator 120 and the pressure chamber 131 of the air tank 110, And a valve for automatically injecting the air discharged from the air tank 110 into the buoyancy regulator 120 when the internal pressure of the buoyancy regulator 131 is reduced to less than the reference pressure.

At this time, a certain portion of the transforming chamber 131 may be connected to a breathing pipe (not shown) in which the diver can breathe in water, and the aeration diver discharged from the air tank 110 may breathe.

1 and 2, an inflator 130 according to an embodiment of the present invention includes an air tank 110 for automatically injecting air discharged from the air tank 110 into the buoyancy regulator 120, Valve.

At this time, the valve according to an embodiment of the present invention automatically opens the air discharged from the air tank 110 by the restoring force when the internal pressure of the variable pressure chamber 131 is reduced to the reference pressure or less, And an elastic valve 132 which can be injected into the valve 120.

In order to achieve the above-described object, the elastic valve 132 may be configured to close the hole 132a formed in the variable pressure chamber 131 when the internal pressure of the variable pressure chamber 131 exceeds the reference pressure. And a spring 132c coupled to the pressing pad 132b and the pressing pad 132b and applying an external force to the pressing pad 132b to open the pressing pad 132b.

At this time, when the internal pressure of the pressure chamber 131 exceeds a reference pressure, more specifically, 50 bar, the pressure pad 132b is pressed by the internal pressure of the pressure chamber 131 to be applied to the pressure chamber 131 And is pressed against the hole 132a and compresses the spring 132c coupled with the pressing pad 132b by the contact of the pressing pad 132b.

Accordingly, when the reference pressure is exceeded, the pressing pad 132b is kept in close contact with the hole 132a, thereby preventing the discharged air from being injected into the buoyancy regulator 120.

Thereafter, the air stored in the air tank 110 is continuously exhausted according to the breath of the diver, and the internal pressures of the air tank 110 and the variable pressure chamber 131 gradually decrease as the air is exhausted.

At this time, when the internal pressure of the transforming chamber 131 becomes the reference pressure, that is, 50 bar or less, the restoring force of the compressed spring 132c becomes larger than the internal pressure of the transforming chamber 131, The pressing pad 132b is released from the hole 132a.

The internal air of the variable pressure chamber 131 is injected into the buoyancy regulator 120 through the hole 132a due to the release of the compression pad 132b, It will rise to the surface of the water.

As a result, the inflator automatic opening and closing apparatus for a skin scuba according to the embodiment of the present invention automatically opens the elastic valve 132 below the reference pressure and inflates the diver by injecting air into the buoyancy regulator 120 , It is not necessary for the diver to check the air storage amount of the air tank 110 from time to time.

As a result, the buoyancy control valve 133 keeps the blocking plate 133b always in close contact with the discharge port 133a by the restoring force of the elastic spring 133d, and only when the diver presses the push button 133e, The closing plate 133b is released from the close contact with the discharge port 133a so that the internal air of the buoyancy regulator 120 is discharged through the discharge port 133a and the external force of the diver applied to the push button 133e is removed The blocking plate 133b is automatically brought into close contact with the discharge port 133a by the restoring force of the elastic spring 133d so that the discharge of the internal air of the buoyancy regulator 120 is blocked.

Hereinafter, an inflator according to another embodiment of the present invention will be described in detail with reference to FIG.

4, the inflator 130 according to another embodiment of the present invention is provided with a pressure sensor 141 inside the transforming chamber 131, and the valve is controlled by the pressure sensor 141 An actuator 142 for opening the air discharged from the air tank 110 to the buoyancy regulator 120 when the internal pressure of the transforming chamber 131 is lower than a reference pressure, And a controller 143 for opening and closing the actuator 142 according to sensing information sensed by the sensor 142.

The inflator 130 according to another embodiment of the present invention differs from the above-described embodiment in that the internal pressure of the variable pressure chamber 131 through the pressure sensor 141 provided in the variable pressure chamber 131 When the air pressure falls below the reference pressure (50 bar), the actuator 142 is operated to open the hole 132a formed in the transforming chamber 131 to inject the air discharged from the air tank 110 into the buoyancy regulator 120 .

Meanwhile, the manual locking means 151 rotates the bolt rod in one direction, so that the bolt rod is moved toward the pressing pad 132b from the inside of the change-over chamber 131.

The rotation of the bolt rod in one direction reduces the opening degree of the elastic valve 132. In particular, when the bolt rod is continuously rotated in one direction, the pressing pad 132b is rotated in the hole 132a The elastic state of the elastic valve 132 can be manually blocked according to the reduced pressure of the transforming chamber 131.

On the contrary, when the bolt rod is rotated in the opposite direction to the one direction, the bolt rod is rotated to the outside of the transforming chamber 131 so that the opening or opening degree of the elastic valve 132 can be adjusted.
