Referring to FIG. 2, the mask 200 that improves the fixing force of the filter may include a body portion 201, a fine hole 203, and a necklace portion 211.

According to one embodiment, a micro hole 203 of a preset size may be located in a region of the body portion 201 corresponding to a position covering the user's mouth and nose. The fine hole 203 may be a hole of a preset size that penetrates the outer and inner surfaces of the body portion 201.

Meanwhile, since masks basically cover the mouth and nose and perform the function of shielding them from the outside, there may be problems with the wearer's breathing. In particular, people suffering from respiratory diseases or the elderly can experience major health problems due to breathing problems. Additionally, the bad smell inside the mask is basically caused by the air inside the mask not being properly ventilated.

According to one embodiment, the micro hole 203 may further include a valve 203a. The valve 203a is partially fixed to one area 201a of the outer surface of the body 201 to cover the micro hole 203, and is installed so that the area excluding the partially fixed area 205 can move freely.

The time check plate 303 is a plate made of copper (Cu) and may be configured to indicate the period of use of the mask through the degree of discoloration due to oxidation by external air.

According to one embodiment, the time check plate 303 may be configured to indicate the usage period of a filter (eg, filter 110 in FIG. 1) mounted on the inner surface of the body portion 301. More specifically, copper (Cu) can cause an oxidation-reduction reaction when it comes into contact with oxygen. Oxygen occupies a certain percentage in the air, and the time check plate 303 causes copper to react slowly due to the oxygen distributed in the air to form a copper oxide (CuO) layer. At this time, the time check plate ( 303) can change color from red to blue-green, and then from blue-green to black.

According to one embodiment, red is the initial color of the time check plate 303, and when oxygen reacts with copper included in the time check plate 303, the color changes from red to bluish green through an oxidation-reduction reaction. It becomes discolored. In addition, when oxygen continuously comes into contact with the time check plate 303, the time check plate 303 may change color from blue-green to black.

According to one embodiment, the user can check when to replace the filter mounted on the inner surface of the body portion 301 according to the degree of discoloration of the time check plate 303. For example, if the time check plate 303 is discolored to blue-green, the user may interpret this as meaning to replace the filter and replace the filter. Additionally, if the time check plate 303 is discolored to black, the user may interpret this as meaning that the filter has expired and replace the filter urgently. The degree of discoloration may vary depending on the proportion of copper contained in the time check plate 303 and the distribution rate of oxygen in the air, but the degree of discoloration may change depending on the effective time of the filter.

Figure 4 is a diagram for explaining a mask filter that improves the fixing force of the filter according to an embodiment of the present invention.

For example, commonly used HIC materials include Cobalt Chloride-Based Material and Copper Chloride-Based Material. For example, cobalt chloride-based material changes from blue to red as humidity increases. Alternatively, it changes to dark brown, and copper chloride systems have the characteristic of changing from colorless to red or dark brown, and the humidity discoloration area 410b according to an embodiment of the present invention can use this to display humidity. For another example, the humidity discoloration area 410b may change color to light blue when exposed to moisture. When moisture continuously comes into contact with the humidity discoloration area 410b and the humidity concentration in the humidity discoloration area 410b increases, the humidity discoloration area 410b may change color from light blue to dark blue. When the humidity discoloration area 410b changes to dark blue, the filter 410 does not properly perform the filtration function, so the user determines when to replace the filter 410 through the saturation of the humidity discoloration area 410b. can do.

According to one embodiment, when the contamination reaction area 410a is discolored by an external contaminant, it may be discolored to a color different from the humidity discoloration area 410b. For example, the humidity discoloration area 410b has a blue color, but when contacted with moisture, only the saturation changes, and the contamination reaction area 410a may change color to red when contacted with external contaminants. there is.
