Description

Oxygen supply mask

The present invention relates to an oxygen-supplied mask, and more particularly, oxygen that can be efficiently used in a disaster accident site causing respiratory distress by intermittently supplying oxygen stored in a compressed oxygen container to allow a wearer to breathe. To provide a fed mask.

When a fire accident occurs in a large building used by a large number of people, many casualties occur. Most life accidents are caused by asphyxiation of toxic gas generated during combustion of a building interior material. However, workers who work in confined spaces (oil and various chemical tanks) under special conditions are also exposed to toxic gases, so they can be easily worn when working in various disasters or confined spaces to maintain breathing for a certain period of time. There is a need for a means to make it possible.

Self-breathing masks that can be worn on the face to provide oxygen to the wearer are used in various disaster accident sites and workplaces where various types of devices are devised and fire or toxic gas is generated.

Conventional self-breathing masks are to provide oxygen into the mask using a compressed oxygen container in most cases, when the locked state of the compressed oxygen container is released to allow oxygen to flow into the mask to maintain breathing.

Since the conventional self-respiratory mask is a structure in which oxygen is continuously supplied when releasing the locked state of the compressed oxygen container, it is impossible to maintain the maximum breathing with a predetermined amount of oxygen. In addition, it was expensive, and some self-breathing masks can control the supply and blocking of oxygen. However, in such self-breathing masks, the wearer compresses with both hands while wearing the mask. By opening / closing the valve installed in the oxygen container or connecting hose to control the supply and blocking of oxygen, the mask wearer cannot use both arms freely, thus limiting the behavior. There is no choice but to.

The present invention was created to eliminate the problems of the conventional self-respiratory mask as described above, and when the solenoid valve is operated while the mask is worn, the oxygen stored in the compressed oxygen container can be intermittently supplied into the mask. By making the maximum use of a certain amount of oxygen, and by freely using both arms even while wearing a mask, when evacuating at various disaster accident sites or when working in a closed workplace with extreme risks To provide a complete oxygen-supplied mask with the focus of the technical problem in order not to limit the wearer's behavior.

In order to realize the above technical problem, the present invention provides a contact pad in close contact with a face portion around a wearer's mouth and nose, a compressed oxygen container compressing and storing a predetermined amount of oxygen, and a diffusion wing plate provided at a discharge port to be located inside the contact pad. The other end is connected to an airtight cover that seals the compressed oxygen container, and is provided on a supply chest to supply oxygen of the compressed oxygen container into the close pad, and a pressure reducing regulator installed on the supply chest to reduce the oxygen supplied from the compressed oxygen container. Supply solenoid valve to control the opening / closing state of the supply valve by installing it on the supply box between the pressure reducing regulator and the discharge port, and control IC to control the opening / closing operation of the solenoid valve at regular intervals. It is composed of a valve control device having a battery for It is to be done.

Oxygen-supplied mask proposed in the present invention is to be worn on the face area around the mouth and nose, and when the wearer operates the solenoid valve, the solenoid valve is intermittently opened and closed by the command of the control IC and the mask is supplied by the supply stand. By intermittently supplying oxygen to the inside, it is possible to minimize the waste of oxygen and make the best use of the specified amount of oxygen. Also, it is possible to breathe without using the arms so that it does not restrict the wearer's behavior. It is easy to take a quick evacuation or take necessary actions and measures at the scene of an accident, and does not restrict the wearer's various working behaviors.

Embodiment of the Invention

A preferred embodiment of the oxygenated mask 10 presented in the present invention is shown in FIG. 1 and a reference perspective view of the main parts of the present invention is shown in FIG. 2, as shown in the present invention. The pad 20 in close contact with the face of the face, a compressed oxygen container 30 that compresses and stores a certain amount of oxygen, and the supply pad 60 that connects the contact pad 20 and the compressed oxygen container 30 to each other. It can be seen that the configuration, the preferred embodiment of the present invention is made as follows.

The supply cup 60 is provided with a diffusion wing plate 90 in the discharge port 61 so as to be located inside the contact pad 20 (face direction of the wearer) to the oxygen pads to be supplied through the discharge port 61 20) to be spread inside, and the other end of the supply container 60 is connected to the airtight cover 40 which seals the compressed oxygen container 30 to seal the oxygen of the compressed oxygen container 30 to the contact pad 20. Configure to supply internally.

The pressure reducing regulator 50 is installed on the supply barrel 60 so as to reduce the oxygen supplied from the compressed oxygen container 20, and the supply barrel 60 between the pressure reduction regulator 50 and the discharge port 61. By installing a solenoid valve 80 on the top is configured to control the opening and closing state of the supply barrel (60).

One side of the solenoid valve 80 is installed by installing a valve control device 70 having a control IC for controlling the opening and closing operation of the solenoid valve 80 at a predetermined interval and a battery for supplying power required for driving do.

The present invention having the above configuration is used to wear to the head of the user using a fixing band (B) attached to the contact pad 20, as shown in Figure 3 by the contact pad 20 by the mouth and nose When the valve control device 70 is operated while being worn to cover the surrounding face part, the solenoid valve 80 is repeatedly opened and closed at a predetermined interval by the control of the control IC built in the valve control device 70. Oxygen supplied through 60 is to be intermittently supplied to the contact pad 20.

According to the present invention, the compressed oxygen container 30 is used as an oxygen source, and the oxygen supplied from the compressed oxygen container 30 is reduced in pressure by the reduced pressure regulator 50 to be supplied at an appropriate pressure. (Size) It is possible to use for a long time in contrast, by controlling the solenoid valve 80 so that the supply of intermittent oxygen can be prevented unnecessary waste of oxygen, the wearer by allowing breathing without using both arms It does not limit the behavior of.
