In general, yellow sand is a phenomenon in which fine sand dust ascending to high altitude by strong winds in Mongolia and northern part of northern China meets the upper westerlies and is carried to the peninsula and descends gradually. Fine dust is very thin and small dust particles that are invisible to our eyes but it is a substance that accumulates in the alveoli of people and causes various diseases. If the particle size of the dust is less than 10 μm, it is classified as fine dust, and when it is less than 2.5 μm, it is classified as ultrafine dust.

In Korea, the number of days of dust and fine dust increases rapidly each year, and statistics show that the figure has increased about five times in three years. Environmental pollution such as the atmosphere is getting worse.

Fine dusts cause harm to human body such as lung disease, asthma, headache, atopy, insulin resistance, and especially dangerous to elderly, pregnant women and fetus. Studies have shown that the risk of low birth weight increases from 5.2% to 7.4% and the risk of stillbirth between the ages of 4 and 9 months is increased to 8.0 to 13.8% if the fine dust concentration increases by 10 μg / m ³ .

The most common way to block these fine dusts is to wear a disposable or reusable mask to cover the nose and mouth when going out. The mask uses a passive blocking method in which the mask and the face portion are closely contacted to prevent fine dust from entering from the outside.

In addition, it may be possible to maintain the air quality by performing control of the blowing unit 200 through the measurement result of the fine dust concentration, or to alarm the wearer by estimating the replacement time of the filter unit 300.

For reference, the following methods can be used to detect and measure fine dust.

First, it can be measured by light scattering method. The light emitted from the light source is collimated through the lens, and then the light passes through the fine tube passing through the fine dust particles, and the semiconductor type array sensor by the photoelectric effect detects the amount of light. That is, when the fine dust particles enter the fine tube, scattered light is generated while meeting the light. The size of the fine dust particles is determined by the size of the particles, and the number of the fine dust particles can be known by counting the number.

Second, it can be measured by the weight collection method. The fine dust (PM ₁₀₎ in the room air on a filter paper of 1 to 30 and collected by the air flow rate of about L / min using the difference in filter paper weight before and after the sampling is to measure the particulate matter (PM ₁₀₎ concentration in the room air . The fine dusts, collectively referred to as PM ₁₀ (particulate matters), are aerodynamically dust particles with a diameter of less than 10 μm.

Third, it can be measured by the beta ray absorption method. The beta rays irradiated from the light source emitting the beta rays are measured as the difference of the beta rays absorbed and extinguished when passing through the dust collected on the filter paper. The beta rays are generated by using Kryton-85 atom or Carbon-14 atom as the light source of the beta ray. The beta ray dose through the filter paper is measured by using a GM tube such as a radiation sensor.

The present embodiment may use various fine dust detecting sensors 800 using the above-described method and other known techniques.

The main body 130 may be provided with a display unit 115 for displaying at least one of the above-described sensing results of the pressure sensor 600, the temperature sensor 700, and the fine dust sensor 800.

For example, the display unit 115 may include a display for displaying numerical values of the fine dust concentration, temperature, and pressure, LEDs for indicating the degree of fine dust contamination and replacement timing of the filter unit 300 in color (alarm) And a speaker for performing audible alarms.

On the other hand, as described above, the operation of the blowing fan can be controlled in conjunction with the pressure, temperature, and fine dust measurement result inside the mask 1 in the blowing fan of the blowing section 200. In order to perform such control more efficiently, as shown in FIG. 7 and FIG. 8, the display unit 115 and the power supply unit 200 may be wirelessly connected to the smartphone 30 so that their operation can be controlled.
