DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. In describing the present embodiment, the same designations and the same reference numerals are used for the same components, and further description thereof will be omitted.

1 and 2 are views showing an oxygen mask according to a first embodiment of the present invention.

1 and 2, the oxygen mask according to the first embodiment of the present invention includes an external housing 100, an internal housing 300, an oxygen supply unit 200, an initial breathing valve 700, A bag 800, a filter unit 810, and a temperature control module 830.

The external housing 100 is provided to surround the user's head to prevent external air from being introduced into the external housing 100 and to prevent the user's head from being exposed to flames, to be.

The external housing 100 may be formed so as to surround the user's head by inserting the user's head through the opening formed at one side thereof and locating the user's head within the accommodating space formed therein.

Further, the outer housing 100 may have a sealing and waterproof structure, and may be formed of a hard material to effectively protect the outer impact. However, it is natural that this does not limit the scope of the rights.

For example, the exterior housing 100 may be formed of a synthetic resin material having a predetermined hardness, or may be formed of a flame-retardant reflective material so that the face of the user can be informed to a third party while protecting the face from a flame.

Particularly, in the present embodiment, the exterior housing 100 includes a body 120 formed to surround a user's head, a first body 110 provided on the body 120 to surround the outside of the oxygen supply unit 200, And a second accommodating part 130 provided in the body part 120 to enclose a breathing bag 800 to be described later.

More specifically, the first accommodating portion 140 and the second accommodating portion 130 are protruded from the body portion 120, and at least a portion of the body portion 120 is provided with a user- A transparent portion having transparency can be provided so that it can be easily visually confirmed.

The external housing 100 may include a face protection unit 110 provided in front of the built-in housing 300 to be described later. A plurality of ventilation holes 112 may be formed in the face protecting portion 110. Inside the ventilation holes 112, a filter for removing a high concentration of carbon dioxide, which the user discharges during breathing, 810 < / RTI >

The built-in housing 300 may be provided on the front side of the user's face in the accommodation space. When the pressure inside the accommodation space increases to a predetermined pressure or more, the air inside the accommodation space is discharged to the outside of the accommodation space And a respiration unit 310 including an exhaust port and an inlet for introducing purified outdoor air containing oxygen into the interior of the accommodation space for the user's breathing.

The inlet of the respiration unit 310 may not necessarily be required if oxygen can be supplied to the user by only the oxygen supply unit 200 to be described later. However, the purified air containing oxygen may be supplied to the user through the inlet of the respiration unit 310, It is possible to reduce the amount of oxygen introduced into the oxygen supply unit 200 and to increase the service life of the oxygen supply unit 200 or to reduce the capacity of the oxygen supply unit 200. [

The inlet of the breathing unit 310 may include an auxiliary filter (not shown) for introducing purified air containing oxygen into the receiving space. The auxiliary filter serves to filter out harmful components from the outside air supplied to the user. The structure and the shape of the auxiliary filter can be varied, and thus the scope of the right is not limited.

The oxygen supply unit 200 is a component that is provided in the built-in housing 300 and supplies oxygen for respiration of the user. The oxygen supply unit 200 may be configured in any form as long as it can supply oxygen, such as an oxygen compression vessel or an oxygen generator, It is natural that this does not limit the scope of the rights.

The oxygen supply unit 200 may include a storage tank 210 for storing oxygen and a regulator 220 for supplying oxygen to the user at a predetermined flow rate. At this time, the regulator 220 controls the flow rate of oxygen discharged from the storage tank 210 to supply oxygen to the user at a predetermined flow rate.

That is, since the regulator 220 is provided in the oxygen supply unit 200, excessive oxygen can be prevented from being supplied to the user by controlling the flow rate of oxygen supplied to the user.

The oxygen supply unit 200 may include a safety unit (not shown) that automatically discharges oxygen when the temperature inside the accommodation space is higher than a preset temperature or when the internal pressure of the oxygen supply unit 200 is higher than a preset pressure. As shown in FIG.

The discharge port of the respiration unit 310 is a component installed in the built-in housing 300 and discharges the air inside the accommodation space to the outside of the accommodation space when the pressure inside the accommodation space increases to a predetermined pressure or more .

As described above, since the external housing 100 is provided so as to surround the head of the user, the inside of the external housing 100 will be a substantially enclosed space, so that the air discharged during the breathing of the user is stored in the external housing The ventilating part 310 may be opened or closed by the ventilating part 310 when the pressure of the receiving space inside the enclosure 100 increases to a predetermined pressure or more, The air inside the space can be discharged to the outside of the exterior housing 100.

At this time, when the uncleaned outside air enters into the receiving space through the outlet of the respiration part 310, the effect of the oxygen mask according to the present invention may be deteriorated. Therefore, the discharge port of the respiration unit 310 may be formed as a one-way valve that discharges the air inside the accommodation space to the outside of the enclosure 100 while blocking the inflow of the outside air.

The initial breathing valve 700 includes an air flow path for supplying air required for a user's initial breathing from the outside of the exterior housing 100 into the accommodation space.

That is, when the user performs the initial breathing while the exterior housing 100 is mounted, the initial breathing valve 700 introduces the air outside the exterior housing 100 into the accommodation space by the inspiration .

According to the initial breathing valve 700 described above, the user can omit the process of blowing air into the breathing bag 800 immediately before using the oxygen mask, so that the user can conveniently and quickly use the oxygen mask.

In addition, the initial breathing valve 700 may be switched to an unused state after the user's initial breathing. This is to prevent the continuous inflow of outside air into the receiving space. That is, the initial breathing valve 700 can prevent the air inside the exterior housing 100 from being contaminated by introducing the outside air only once at the initial breathing of the user, and preventing the air from being used afterwards.

At this time, since the pressure inside the exterior housing 100 can be maintained at a certain level after the initial breathing, the valve of the initial breathing valve 700 is opened by the pressure only during the initial breathing process and is not opened after the initial breathing .

It will be appreciated that the initial respiratory valve 700 may be omitted as an example.

The filter unit 810 is provided in the built-in housing 300 and removes at least a part of the carbon dioxide contained in the user's exhalation.

Generally, the oxygen contained in the inhalation is metabolized in the body and excreted in the exhalation, about 4.5% of the oxygen is converted to carbon dioxide. Conventionally, a method of directly discharging the air containing carbon dioxide converted during the breathing process to the outside is applied. However, in the present invention, the use time of the oxygen mask can be prolonged remarkably through the technique of breathing the air.

That is, the filter unit 810 is provided on the air flow path by the respiration of the user, and can remove carbon dioxide contained in the user's exhalation by adsorption or convert the oxygen into oxygen through a chemical reaction. The carbon dioxide adsorbing material may be an alkali metal hydroxide, silica, polyethyleneimine or the like, but the kind of the oxygen adsorbent and the oxygen conversion material through the chemical reaction is not limited thereto.

At this time, a breathing bag 800 may be connected to the front of the filter unit 810, and a mouthpiece 850 may be provided behind the filter unit 180 to allow the user to drink water.

In this embodiment, in order to allow the user to exhale breath through the outlet of the respiration unit 310 described above, the air in the one direction is supplied between the filter unit 180 and the mouthpiece 850 A check valve 820 having a flow path may be further provided. In this case, the oxygen supplied through the oxygen supply unit 200 may be supplied to the user through the check valve 820.

On the other hand, the above-described carbon dioxide removal process is influenced by temperature. Therefore, the carbon dioxide removal rate varies depending on the use conditions of the oxygen mask such as the season of use of the oxygen mask and the use area.

As shown in the graph shown in FIG. 4 and the following Table 1, it can be seen that the lower the temperature, the more gradually the carbon dioxide removal rate per hour decreases.

That is, depending on the use condition of the oxygen mask, the performance of the filter unit 810 is fluid, and the carbon dioxide removal rate will be greatly lowered especially in a cold region or underwater region where the temperature is low.

In order to solve such a problem, the temperature control module 830 may be further provided in the present invention.

That is, the temperature control module 830 controls the temperature of the air flow path by the user's breathing, so that the carbon dioxide removal rate can be controlled as desired without being limited to the external environment.

The temperature sensing module 830 may further include a temperature sensing module 840 sensing the temperature of the air flow path by the user's breathing in the present embodiment, And the temperature of the air flow path by the user's breathing can be controlled based on the result.

At this time, the temperature control module 830 may maintain the carbon dioxide removal rate uniformly, but it is also possible to control the carbon dioxide removal rate to be varied according to the situation.

In the present embodiment, the temperature sensing module 840 is provided inside the exterior housing 100, and the temperature control module 830 surrounds the filter unit 810. However, The position of the temperature control module 840 and the temperature control module 830 are not limited thereto and may be provided at various other positions.

Hereinafter, the breathing process using the oxygen mask of the present invention will be described with reference to FIGS. 5 to 8. FIG.

First, as shown in FIG. 3, the breathing bag 800 is in a contracted state at the beginning of use. As described above, in the prior art, it is possible to use after blowing air into the breathing bag 800. However, in the present invention, when the breathing bag 800 is contracted by the initial breathing valve 700, The mask can be used quickly.

When the user breathes air for initial breathing, air is introduced from the outside through the initial breathing valve 700 into the interior of the accommodation space.

Then, when the user exhales the air to be breathed for the initial breathing, air enters and expands into the breathing bag 800 as shown in FIG.

Also, since the user's exhalation has a state in which the oxygen amount is reduced compared to the air introduced into the body by inhalation, the filter unit 830 can remove carbon dioxide contained in the exhalation or convert it into oxygen for re-breathing.

If the total amount of oxygen decreases in the above process, the oxygen supplying unit 200 can discharge the amount of oxygen corresponding to the reduced amount of oxygen to the user side to compensate for the reduced amount of oxygen.

If the user continuously performs breathing, the breathing bag 800 repeats expansion and contraction as shown in FIGS. 6 and 7. Similarly, in this process, the filter unit 830 performs the breathing The carbon dioxide contained in the exhalation may be removed or converted to oxygen, and the gradually decreasing amount of oxygen may be compensated for by the oxygen supply unit 200.

However, when the above process is repeated, oxygen is further generated by the oxygen supply unit 200 in a state where the amount of air inside the accommodation space is constant, so that there is a problem that the pressure inside the accommodation space continuously increases.

Accordingly, as shown in FIG. 8, when the pressure of the breathing portion 310 of the built-in housing 300 is increased to a predetermined pressure or higher, And is discharged to the outside of the housing 100. As a result, the pressure inside the accommodation space can be maintained at a certain level.

9 is a view showing an oxygen mask according to a second embodiment of the present invention.

In the case of the second embodiment of the present invention shown in FIG. 9, the temperature sensing module 840 is provided inside the filter unit 840, different.

That is, in the present embodiment, the temperature sensing module 840 is directly exposed to the air flow path during respiration of the user, so that the temperature of the expiration can be more effectively and accurately controlled through the temperature control module 830 .

The temperature sensing module 840 and the temperature control module 830 may be located at various positions as in the present embodiment.

It will be apparent to those skilled in the art that the present invention can be embodied in other specific forms without departing from the spirit or scope of the invention as defined in the appended claims. It is obvious to them. Therefore, the above-described embodiments are to be considered as illustrative rather than restrictive, and the present invention is not limited to the above description, but may be modified within the scope of the appended claims and equivalents thereof.
