A schematic cross-sectional view of an exemplary portable oxygen supply device according to the present invention.

As shown, the portable oxygen supply device 1 of the present invention, the oxygen can mounting portion 10, the decompression unit 20, the flow control handle 30, the oxygen discharge port 40, the mask 50 and the operation switch (60) is basically included.

The oxygen can mounting portion 10 is formed below the housing 3. The oxygen can mounting portion 10 is formed in a shape corresponding to the outer contour of the upper end of the oxygen can 2 so that the oxygen can 2 can be fitted and fitted to fit snugly. The small oxygen can 2 formed of an aluminum alloy is replaceably combined. Therefore, when the oxygen can 2 is coupled to the oxygen can mounting unit 10, the inlet of the oxygen can 2 communicates with the oxygen passage inside the housing 3, and oxygen is discharged from the oxygen can 2 to the housing 3. It becomes possible.

The housing 3 is provided with a decompression unit 20 for decompressing oxygen discharged from the oxygen can 2 in a high pressure state to a low pressure. As the decompression unit 20, a known structure capable of reducing the pressure by the area ratio can be applied by passing oxygen from a relatively narrow area to a large area.

The pressure reducing section 20 shown in Fig. 3 is in communication with the oxygen can 2 and has an oxygen passage 21 having an orifice 21A formed at its end, and a taper portion 22A for selectively opening and closing the orifice 21A. Is formed in the valve 22, the spring 23 pressurizing the valve 22 toward the closing of the orifice 21A, the cylinder 24 formed downstream of the orifice 21A, and the cylinder 24. A piston 25 which is mounted to be movable left and right and is in contact with an end of the valve 22, and pressurizes the piston 25 so that the valve 22 receives a force to move toward the opening of the orifice 21A. An example involving the spring 26 is illustrated.

According to the structure of such a decompression | restoration part 20, the high pressure oxygen from the oxygen can 2 is pressure-reduced to the pressure which is moderate to inhale, passing through the wide cylinder 24 from the orifice 21A of narrow cross-sectional area.

The valve 22 of the decompression unit 20 tapers the oxygen of the cylinder 24 against the sum of the pressure of oxygen acting from the oxygen can 2 through the oxygen passage 21 and the elastic force of the spring 23. The amount of oxygen passing is varied by moving left and right according to the equilibrium state of the pressure acting on the portion 22A and the elastic force of the spring 26.

The decompression unit 20 is provided with a flow control handle 30 for adjusting the amount of oxygen discharged to the oxygen discharge port 40. As illustrated in FIG. 3, the flow regulating handle 30 retreats by rotating integrally with the handle 31 which is turned by hand and the handle 31, and has a spring cap on the spring 26 of the decompression unit 20. It can comprise with the screw shaft 32 which contact | connects through (33).

Accordingly, when the handle 31 of the flow control handle 30 is rotated, the screw shaft 32 moves forward and backward according to its rotational direction to change the equilibrium state by varying the force of the spring 26 applied to the piston 25. The valve 22 is moved, thereby changing the size of the gap between the orifice 21A and the tapered portion 22A through which oxygen passes, thereby varying the amount of oxygen passing through.

Therefore, the user can block the oxygen discharge by rotating the flow control handle 30 to an appropriate position between full / lock, as well as to adjust the amount of oxygen discharged.

Oxygen passing through the decompression unit 20 is discharged out of the housing 3 through the oxygen outlet 40. That is, the oxygen from the oxygen can 2 is discharged to the outside through the oxygen outlet 40 after being decompressed to a pressure suitable for inhalation via the decompression unit 20, and the user exits through the oxygen outlet 40. Inhale oxygen.

According to a feature of the present invention, the oxygen passage between the decompression unit 20 and the oxygen outlet 40 is provided with an operation switch 60 for intermitting the oxygen discharge to the oxygen outlet (40).

The operation switch 60 applicable to the present invention is not particularly limited as long as the user presses the hand by the oxygen discharge port 40 through the oxygen discharge port 40 and removes the pressing force so that the oxygen is blocked.

3 to 7, the operation switch 60 may be configured to include a valve body 61, a valve 64, and a pusher 65.

The valve body 61 is provided with an oxygen inlet 62 communicating with the decompression unit 20 and an oxygen outlet 63 communicating with the oxygen outlet 40, and the oxygen outlet 40 and the oxygen outlet 63 are provided in the valve body 61. For example, it can arrange in a 90 degree direction. The decompression unit 20 and the oxygen inlet 62 are connected to the oxygen passage 62A, and the oxygen outlet 63 connects the oxygen discharged to the oxygen outlet 40 to, for example, a plastic pipe or the like. 63A is connected.

The valve 64 is mounted in the valve body 61 and is forced to move toward the sealing portion of the oxygen inlet 62. Therefore, when no external force is applied, since the valve 64 seals the oxygen inlet 62, oxygen is not discharged to the oxygen outlet 40. Reference numeral 64A is an O-ring for confidentiality.

A head 65 of the valve 64 is connected to a pusher 65 which transmits a force pressurized by the user to the valve 64. Therefore, when the pusher 65 is pressed by hand, the valve 62 is moved to open the oxygen inlet 62 so that oxygen is discharged through the oxygen outlet 40. Reference numeral 65A denotes a cap covering the head side of the pusher 65.
