In one embodiment, the skin is a waterproof, non-woven fabric.

In one embodiment, the alkaline filter layer is an antibacterial dust filter cotton with an alkaline neutralizing substance and an acid-base indicator attached thereto.

In one embodiment, the inner layer is a hydrophilic nonwoven fabric.

In one embodiment, the alkaline neutralizing material is sodium bicarbonate.

In one embodiment, the acid-base indicator is a blue litmus reagent.

In another embodiment, the alkaline mask further has a receiving space, an opening, and a closure member. The accommodating space is located between the surface layer and the inner layer to accommodate the alkaline filter layer. The opening is located at a lower end of the body and communicates with the receiving space. The closing element is correspondingly disposed at the opening.

In another embodiment, the closure is a zipper, fastener or fastening strip.

The alkaline mask of the present invention neutralizes the filtered acidic substance by the alkaline neutralizing substance and the acid-base indicator attached to the alkaline filter layer, and exhibits a color change when the alkaline mask cannot filter the acidic substance.

Hereinafter, the embodiments according to the present invention will be described in detail with reference to the accompanying drawings, which will be readily understood by those skilled in the art. The authoring of the invention may take a variety of variations, and should not be limited to only those embodiments. The following embodiments omit the description of well-known parts, and the same reference numerals are used to refer to the same or similar elements.

Fig. 1 is a view showing the structure of an alkaline mask in an embodiment of the present invention. Referring to FIG. 1 , the alkaline mask 100 may include a main body 1 and fixing members 2 connected to the left and right sides of the main body 1 . The body 1 may include a skin 12, an alkaline filter layer 14, and a back layer 16 from the outside to the inside. The alkaline filtration layer 14 is a filtration layer on which the alkaline neutralizing substance 142 and the acid-base indicator 144 are adhered to the fibrous base material 141.

When the environment contains a gaseous acidic substance, the user wears the alkaline mask 100 through the fixing member 2, and the alkaline neutralizing substance 142 of the alkaline filter layer 14 neutralizes the acidic substance in the air to achieve the filtration acidity. The effect of matter. When the alkaline neutralizing substance 142 is depleted by the neutralization reaction, the acid-base indicator 144 can react with the unneutralized acidic substance and produce a color change, thereby changing the color of the basic filter layer 14.

In the present embodiment, the fixation element 2 can be, for example, an ear strap type strap. When the user wears the alkaline mask 100, the fixing member 2 is circumferentially fixed to the ear of the user, thereby fixing the alkaline mask 100 to stably cover the mouth and nose of the user and attaching the face. In another embodiment, not shown, the fixation element 2 can be, for example, a head-mounted strap that is attached to the entire head of the user.

The alkaline mask 100 may further include a flexible bead 3 disposed at the upper end of the body 1, preferably at the upper end of the skin 12. When the alkaline mask 100 stably covers the user's mouth and nose and attaches to the face, the flexible bead 3 can correspond exactly to the position of the nose bridge of the user. At this time, the user can apply the pressure to the flexible bead 3 so that the flexible bead 3 deforms and fits the bridge of the nose, thereby avoiding the sliding of the mask and also increasing the adhesion effect of the alkaline mask 100.

For the convenience of understanding, the structure of each layer of the main body 1 of the present embodiment will be further described below.

The surface layer 12 can initially block the outside moisture or large particle dust from infiltrating into the interior of the inlet cover. In this embodiment, the surface layer 12 can be a waterproof non-woven fabric, in addition to avoiding the outside moisture from infiltrating into the interior of the cover, and avoiding bacteria or viruses accompanying moisture or foam. Infiltrate the inlet cover. In addition, the surface layer 12 may be a transparent material for the user to observe and confirm the color change of the acid-base indicator 144 in the alkaline filter layer 14.

The alkaline filtration layer 14 can filter fine dust and antibacterial in addition to the acidic substance. In the present embodiment, the fibrous base material 141 of the alkaline filtration layer 14 can be, for example, an antibacterial dust filter cotton cloth. The alkaline neutralizing substance 142 and the acid-base indicator 144 may be attached to the fibrous base material 141.

The manner in which the alkaline neutralizing substance 142 and the acid-base indicator 144 are attached to the fibrous base material 141 is not limited. In the present embodiment, for example, the alkaline neutralizing substance 142 and the acid-base indicator 144 are dissolved in water. After the mixed solution is formed, the fibrous substrate 141 is immersed in the mixed solution, and then taken out and dried, whereby the basic filter layer 14 to which the basic neutralizing substance 142 and the acid-base indicator 144 are adhered to the fibrous base material 141 is obtained.

Among them, the alkaline neutralizing substance 142 is a water-soluble alkaline substance, and in the present embodiment, for example, sodium hydrogencarbonate, sodium carbonate or calcium hydroxide, preferably sodium hydrogencarbonate. The acid-base indicator 144 can produce a color change in the presence of an acid in a humidified environment. In this embodiment, for example, a blue litmus reagent can be turned into a red color when the litmus reagent reacts with an acid.

The inner layer 16 is in contact with the skin for a long time, and is preferably capable of absorbing sweat and oil secreted by the skin to enhance the wearing comfort. In the present embodiment, the inner layer 16 may be, for example, a hydrophilic nonwoven fabric.

The use of the alkaline mask 100 will be exemplified below. When the user wears the alkaline mask 100 in an environment having a gaseous acidic substance, the acidic substance neutralizes the alkaline neutralizing substance 142 attached to the fibrous base material 141 to eliminate and filter the acidic substance, thereby Avoid irritating damage to the user's respiratory tract.

However, the alkaline neutralizing substance 142 is gradually consumed as the neutralization reaction proceeds, and when the alkaline neutralizing substance 142 is exhausted, the alkaline filtration layer 14 loses the filtering effect and accumulates the acidic substance, and is even sucked into the respiratory tract. in. Therefore, the alkaline filter layer 14 in the embodiment further has an acid-base indicator 144 attached thereto, which can absorb the moisture exhaled by the human body or the environment, is wetted, and reacts with the accumulated acidic substances to produce a color. Variety. The color change appearing through the alkaline filter layer 14 can prompt the user to replace the alkaline mask 100 to ensure protection against acidic substances.

In detail, when the acid-base indicator 144 is a blue litmus reagent, the alkaline mask layer 100 exhibits a blue color in an unused state. When the alkaline neutralizing substance 142 is depleted, the wet blue litmus reagent contacts the acidic substance and turns from blue to red, so that the alkaline filter layer 14 appears red, thereby reminding the user to replace Alkaline mask 100.

2 is a schematic view of an alkaline mask of a replaceable alkaline filter layer in another embodiment. Compared to the alkaline mask 100 of Fig. 1, the basic mask 1 of Fig. 2 may further include a receiving space S formed between the skin 12 and the inner layer 16 to accommodate the alkaline filter layer 14. The lower end of the main body 1' and the communication space S are provided with an opening M, and the corresponding opening M is further provided with a closing member 6 which can close the opening M.

The closing member 6 is not limited as long as it can open and close the opening M. In the present embodiment, the closure element 6 can be, for example, a zipper. In another embodiment, not shown, the closure element 6 can also be a fastener or a fastening strip.

The manner in which the alkaline filtration layer 14 is replaced will be exemplified below. When the user wears the alkaline mask 200, once the alkaline filter layer 14 is found to be discolored, it represents that the alkaline neutralizing substance 142 on the alkaline filter layer 14 for neutralizing the filtered acidic substance has been exhausted. The opening M is thus opened through the closure element 6, the alkaline filter layer 14 in the receiving space S is replaced from the opening M, and then the opening M is closed through the closure element 6, thus completing the replacement of the alkaline filter layer 14.

The alkaline mask described in the above embodiment is capable of neutralizing and filtering gaseous acidic substances in the air. In addition, when the alkaline mask loses the function of filtering the acidic substance, the acid substance will change the color of the alkaline filter layer when it accumulates on the alkaline mask, so the user can be reminded to replace the mask or replace the alkaline filter layer.
