First, referring to FIG. 1 , it can be seen that FIG. 1 shows an application example of an oxygen patch attached to a mask.

In FIG. 1A, an example of an oxygen patch 1 attached to a disposable dental mask is shown, and in FIG. 1B, an example of an oxygen patch 1 attached to a health mask with particle blocking performance such as KF94 and KF80 is shown have.

As shown in FIGS. 1A and 1B , the oxygen patch 1 attached to the mask developed in the present invention has a rectangular parallelepiped shape, unlike the conventional oxygen generator manufactured in a circular shape, so it is a health mask. Of course, it is characterized in that it has a shape that can be easily applied to a disposable dental mask in which wrinkles are formed.

Meanwhile, in order to examine the internal structure of the oxygen patch attached to the mask in more detail, it will be described with reference to FIGS. 2 to 7 .

First, looking at the main configuration of the oxygen generating patch attached to the mask with reference to FIG. 2 , the oxygen generating patch attached to the mask of the present invention includes the reaction solution impregnated part 10 in which the porous filter member is impregnated with the reaction solution, A solid oxygen storage unit 20 that stores solid oxygen to generate oxygen through a chemical reaction with the reaction solution supplied from the reaction solution impregnation unit 10, and oxygen generated by a chemical reaction between the reaction solution and solid oxygen is used by the user and an oxygen inlet 30 having an inflow path 31 formed therein for introducing the mask into the mask that is being worn.

Specifically, the above-described reaction solution impregnated part 10 may preferably use purified water as a reaction solution, and a hydrophilic material is used as a porous filter member so that purified water used as a reaction solution can be stored for a certain period of time. , a material that allows the reaction solution to be stored for a certain period of time and then exported may be used.

As an embodiment, a carbon filter may be used as the porous filter member of the reaction solution-impregnated part 10. This carbon filter goes beyond providing the function of storing the reaction solution for a certain time, and It is possible to further provide a function of water purification to adsorb the contained residual foreign substances.

Such a carbon filter may be used in the form of block activated carbon in which granular activated carbon is blocked, but is preferably used in the form of activated carbon fiber processed into a fiber state, occupying a small volume, while having a function of supporting the reaction solution and the reaction solution It can be made to provide the integer function of .

Meanwhile, as another embodiment, as the porous filter member of the reaction solution-impregnated part 10 described above, a membrane filter having excellent water absorption ability may be used, but the present invention is not limited thereto.

Next, as described above, solid oxygen is stored in the above-described solid oxygen storage unit 20 . In this case, the solid oxygen preferably uses potassium acetate and sodium peroxide as an oxidizing agent, and may include at least one or two or more of calcium hydroxide, aluminum hydroxide, and magnesium hydroxide as a stabilizer.

Specifically, the above-mentioned potassium acetate exists as a yellow solid, and is generated when potassium is heated for a long time while passing through dry air in a glass tube. It reacts with water to release oxygen and produces potassium hydroxide (KOH) (see Scheme 1), and is known as a strong oxidizing agent.

The above-mentioned sodium peroxide exists in yellowish-white granular or powdery form, and is called sodium peroxide or sodium dioxide. It performs the function of an oxidizing agent that reacts with water to produce sodium hydroxide, NaOH and oxygen (refer to Scheme 2).

At this time, the above-mentioned calcium hydroxide is a basic compound of white powder, and although it is not soluble in water to such a degree that only about 0.82 g is dissolved in 1 L of water, it has a high degree of ionization (dissociation). For this reason, calcium hydroxide dissolved in water has a strong basicity of about 12.5 pH.

On the other hand, when the above-mentioned calcium hydroxide reacts with carbon dioxide (CO ₂ ), which is a greenhouse gas, carbon dioxide can be converted into calcium carbonate (refer to Scheme 3) or calcium hydrogen carbonate (refer to Scheme 4) through the following reaction formula, so that in treating carbon dioxide can also be useful.

The above-mentioned aluminum hydroxide is an amphoteric hydroxide as a hydroxide of aluminum, and when reacted with an acid, an aluminum salt is generated, and when it reacts with an alkali, it becomes an aluminate. In particular, when it is in contact with water for a long time, it is gelled, and the gel-like aluminum hydroxide has strong adsorption properties and thus exhibits strong adsorption properties.

The above-mentioned magnesium hydroxide exists as hydrate talc in nature, and is produced as a colorless colloidal precipitate when an alkali hydroxide acts on a magnesium salt. In addition, if the solid is left in the air, carbon dioxide can be absorbed and discharged as magnesium carbonate, which can be usefully used for the treatment of carbon dioxide, which is a greenhouse gas.

On the other hand, the above-described solid oxygen may include 35 to 50% by weight of the oxidizing agent and 45 to 70% of the stabilizer, and the most preferred ratio of the oxidizing agent and the stabilizer is 35% by weight of the oxidizing agent and 65% by weight of the stabilizer. Calcium hydroxide stabilizes the explosive property of potassium oxide, so it will be understood as the ratio that can most stably generate and supply oxygen, and the reaction formula (Scheme 5) of solid oxygen and purified water is described below.

In order to promote this chemical reaction, the porous filter member of the reaction solution impregnated unit 10 and the solid oxygen of the above-described solid oxygen storage unit 20 may have a structure in which at least one surface is in contact with each other.
