As shown in Figure 1, the conventional propulsion device is connected to a reservoir attached to or fixed to the user's back, and one side of the reservoir, and a nozzle through which the air discharged from the reservoir moves, and the air discharged at the end of the nozzle. A thruster is configured to have it, and the thruster is fixed by binding to the user's ankle.

However, the prior art has a problem that does not match the direction to proceed because the propulsion force cannot be formed in a straight line as it binds to the user's ankle.

Accordingly, the present invention enables users to quickly move in a straight line in the direction they want to move by generating power using a separate air container when performing various other tasks in the water, but a separate auxiliary propulsion is additionally configured, To provide an underwater propulsion device using air with high safety that can have safety by blocking the operation of the propulsion using air and operating the auxiliary propulsion when the air inside the reservoir is less than a set value.

First, before explaining the present invention, the present invention is composed of a reservoir 100 , a thruster 300 , a switch unit 400 , a control unit 500 , an auxiliary thruster 600 , and a main body 700 .

As shown in FIG. 2 , the reservoir 100 is a reservoir 100 substantially containing air therein, and is configured to supply air to the thruster 300 to be described below.

Here, the capacity of the air container 100 can be selectively configured as needed, and some components of the control unit 500 to be described below and some components of the control unit 500 inside are configured separately.

In addition, the reservoir 100 supplies air to the thrusters 300 , and at this time, when one is in the number of the thrusters 300 , it constitutes one outlet, and when the number of the thrusters 300 is a plurality of outlets, a plurality of outlets It is preferable to configure

As shown in FIG. 2 or FIG. 4 , the thruster 300 has a nozzle part 310 that is directly connected to one side of the air container 100 and is formed to be long, and is connected to the end of the nozzle part 310 . Consists of a propulsion unit 320 that generates propulsive force through the discharged air, and a compressed air generating unit 330 that extrudes the air supplied from the air cylinder 100 between the nozzle unit 310 and the air cylinder 100 . do.

That is, the thruster 300 selectively discharges air from the air container 100 according to the operation of the user's switch unit 400. At this time, the discharged air is compressed by the compressed air generating unit 330, and the produced compressed air is discharged toward the propulsion unit 320 through the nozzle unit 310, and finally it is possible to have a propulsive force by the air having a strong pressure.

On the other hand, if the structure of the thruster 300 is described in more detail, as shown in FIG. 4 , the nozzle unit 310 connected to the air cylinder 100 has a passage therein, and the compressed air generating unit ( The air generated from the 330 moves, and the propulsion unit 320 is formed to narrow in the other direction connected to the nozzle unit 310 .

That is, the passage of the propulsion unit 320 is formed to gradually become narrower from the direction connected to the nozzle unit 310 to the other side, so that the compressed air can be ejected more strongly.

This nozzle structure can have a strong driving force, so that limited air can be used efficiently.

On the other hand, as shown in FIG. 4 , a bending part 321 capable of binding a user's body, for example, a waist or a thigh, is configured in the lower portion of the propulsion part 320 , and the bending part 321 is The end is composed of Velcro or a fitable structure so that they can be detached or fitted and separated from each other, thereby maximizing the propulsion force through the user's strong binding.

In other words, when the propulsion unit 320 is not fixed and separated from the user's body, it does not have propulsion in the desired direction and is a technology that replaces flippers in the water. By configuring it, it is possible to have a driving force in a straight direction in a fixed state, so that efficient use is possible.
Although the conventional propulsion device can generally have propulsion by driving a motor, in the present invention, compressed air is formed using air contained in a separate air container 100, and then it is possible to have propulsion.

For example, assuming that the user is active while using the thruster 300 for the expected time underwater by using the present invention, when the minimum amount of air required for the expected time is set through the setting unit 540 , when the amount of air consumption increases by using the thruster 300 and reaches the set value, the signal of the switch unit 400 is blocked so that the air supply unit 520 is no longer operated, and later A separate auxiliary propulsion system is enabled to operate.

In other words, the original purpose of the propulsion device is to allow the user to have propulsion without effort, but if there is insufficient air, it is difficult to reach the desired target point. After the user directly calculates the amount of air consumed according to the expected time, the calculated minimum amount of air is set by the setting unit 540. When the amount of air is less than the set amount of air, the air is blocked and the auxiliary propulsion device is operated. , it is possible to secure safety and convenience in use at the same time.
