The entire diving equipment shown in Fig. 1 has a short air introduction pipe 3 at the upper part and a compressed air conduit 4 of the required length at the lower part, with the hollow chamber 2 formed inside the annular float 1 as the boundary. Air is sent from the end of the air introduction pipe 3 to the compressed air conduit 4 through the air compression mechanism 5 connected and sealed in the hollow chamber 2, and the user always breathes while holding the lower end of the pipe 4 in the mouth. Things.

As shown in FIG. 2, the air compression mechanism 5 includes a rotary compressor 7 integrated with a motor 6 in a hollow chamber 2 integrally formed with the float 1 and a pressure tank 8 formed in a ring shape. The pressure tank 8 is formed by a diaphragm-type pressure-responsive switch 9 provided in a pipe connecting the pressure tank 8 and the compressor 7 and a battery 10 serving as a driving power source of the motor 6 .The air in the pressure tank 8 is preset. When the pressure reaches the predetermined pressure, the motor 6 is stopped via the pressure responsive switch 9, and when the pressure drops below a certain level due to use, the motor 6 is automatically activated, and a certain amount of pressure is always stored in the pressure tank 8. Air is being stored. Reference numeral 11 denotes a removable lid provided in the hollow chamber 2.

The lower end of the air inlet pipe 3 is connected to the compressor 7 and floated. c

Five

1 is upright, and a check valve 12 is interposed at an appropriate place in the middle. The upper end, which is bent downward so that rainwater and splashes do not enter, is provided with an operation switch 13 for opening and closing the drive power source of the motor 6 at the bracket.

The compressed air conduit 4 is suspended from the pressure tank 8 at the bottom of the hollow chamber 2 with an AA at the end, and a mouthpiece 14 for the user is provided at the end, and in the figure, a mouthpiece is attached to the mouth. An opening / closing cock 15 is interposed. The opening / closing cock 15 is arranged such that when the user grips the operating handle 16 of the opening / closing cock 15 together with the tube 4 against the panel, the cock 15 is opened, and when the operating handle 16 is gripped again, the cock is closed.

The mounting port 14 to be connected to the user's mouth of the compressed air conduit 4 is not limited to a mouthpiece but is made into a mask type, and when the mask is mounted, the opening / closing cock 15 opens in conjunction with it. Is also good.

In order to use the diving equipment shown in FIGS. 1 and 2, the diving equipment is floated on water, the operation switch 13 is turned on, the motor 6 is driven, and the recompressor 17 is driven by the motor 6. After that, the user puts the attachment opening 14 to the mouth and opens the opening / closing cock 15 to enter the water, and can dive within the reach of the compressed air conduit 4.

In the diving equipment of the present invention, the air sucked into the pressure tank 8 through the check valve 12 by the tip of the air introduction pipe 3 through the check valve 12 is always maintained at a constant pressure through the pressure responsive switch 9, Inhalation is easy and battery consumption is low.

In FIG. 3, the same reference numerals as those shown in FIG. 1 and FIG. Indicates the same meaning. In Fig. 3, 20 is a float, 21 is a drawstring switch, 22 is a drawstring, 23 is a thin tube, 24 is a bolt, 30 is a compressor inlet tube, 31 is a compressor outlet tube, and 32 and 35 are surroundings. A pipe, 33 is a connection pipe for an air introduction pipe, and 34 is a connection pipe for a compressed air conduit.

The entire diving equipment shown in FIG. 3 is in the form of a hollow container (or tank) ', and the container 20 itself forms a float. The container 20 is composed of an upper wall 25 and a lower wall 26, and is tightly fixed at its periphery by a bolt 24 via a packing material. A motor 6, a compressor 7 and a battery 10 are arranged on the bottom surface of the hollow chamber 2 in this container. A connection pipe 33 is provided through the upper wall 25 of the container 20 so as to penetrate the upper wall 25, and the air introduction pipe 3 is connected to the upper end thereof. A connecting pipe 34 is provided on the lower wall 26 so as to pass through the lower wall 26, and the compressed air conduit 4 is surrounded by a lower end thereof. A connection pipe 32 is connected between a lower end of the connection pipe 33 and an inlet pipe 30 of the compressor 7, and a connection pipe 35 is connected between an outlet pipe 31 of the compressor 7 and an upper end of the connection pipe 34. A thin tube 23 is further provided on the upper wall 25 of the container 20. A drawstring 22 is inserted into the thin tube 23, and the lower end thereof is connected to a drawstring-type operation switch 21. The thin tube 23 can be composed of a plastic tube and a rubber tube, and the inside thereof is filled with a water-repellent material to prevent water from entering from outside.

In the diving equipment shown in FIG. 3, when the operation switch 21 is turned on by pulling the drawstring 22, the motor 6 is driven, and the recompressor 17 is driven by the drive of the motor 6, so that the external air is generated by air. It enters the compressor 7 through the inlet pipe 3 and the connecting pipe 32, where it is compressed. The compressed air is discharged from the compressor outlet pipe 31 through the connecting pipe 34 and the compressed air conduit 4, and from the mounting port 14 connected to the lower end thereof.

The diving equipment shown in FIG. 3 can be variously changed, and for example, the connecting pipe 32 can be omitted. In this case, the external air once enters the hollow chamber 2 of the container 20, and from this hollow chamber passes through the inlet pipe 30 of the compressor and into the compressor. Further, the connecting pipe 34 can be omitted. In this case, the compressed air discharged from the outlet pipe 31 of the compressor 7 enters into the hollow chamber 2 and then enters the compressed air conduit 4 through the connecting pipe 34. Further, a pressure regulating valve is attached to the connection pipe 35, and a part of the compressed air is discharged into the container 20, and the inside of the container can be filled with the compressed air at a constant pressure. In this case, since the inside of the container is pressurized, even if there is a minute gap at the junction between the upper wall 25 and the lower wall 26 of the container, water from the minute gap to the inside of the container is Intrusion is prevented. Furthermore, as shown in FIG. 1, the operation switch 21 can be attached to an appropriate portion of the air introduction pipe 3.

In the diving equipment shown in FIGS. 1 to 3, the electric wiring connecting the motor, the battery, and the operation switch is omitted.
