Description

Wearable Air Cleaner Having Ion Generator {Wearable Type Air Cleaner Having Ion Generator}

The present invention relates to an air purifier, and more particularly, to a wearable air purifier having a structure that can be worn on the face or head of a wearer.

In general, an electric dust collector is a device that removes particulates such as dust mixed in the air by using an electrode that causes corona discharge.When a discharge is induced by passing air between the electrodes, the particulates in the air receive electrical force and It has a structure that sticks to the dust collecting plate and is removed.

1 is an example of such an electric precipitator, and shows a structure disclosed in US Patent 4,514,195. As shown in the figure, the electric dust collector 10 includes an insulating housing 12 provided with an inlet 24 and an outlet 26 through which air enters and exits, and a plurality of discharge electrodes 20 and dust collecting plates 23 installed in the housing 12. ), etc. Therefore, when a discharge occurs in the discharge electrode 20, dust mixed in the air 28 passing through the housing 12 adheres to the dust collecting plate 23, and the clean air 28 from which the dust has been removed is transferred to the outlet 26. It will escape through. However, in such a dust collector 10, since the discharge electrode 20 is formed in a flat rod shape, there is a disadvantage in that the electric force acting on the dust cannot be concentrated and weakened by the discharge. That is, when the electric force is concentrated and acts, the dust can be strongly pushed to the dust collecting plate 23, but if the discharge electrode 20 is in a flat shape, the concentration effect is reduced, so that sufficient force cannot be exerted.

Moreover, such an electric precipitator has a disadvantage of generating a large amount of ozone by ionizing air by corona discharge generated by high voltage, and generating secondary pollutants in the process of ionizing harmful gases when treating other harmful gases. In order to increase the collection efficiency, a higher voltage must be applied to the dust collecting electrode, and as the voltage increases, the current also increases, resulting in a lot of power consumption. In addition, since the discharge electrode and the earth electrode are metal, corrosion is easily caused by strong acidic harmful gases, and there are many problems in durability.

In particular, ozone generation from electric precipitators is a precipitator method currently used in homes, which is an obstacle to the use of electric precipitators. For installation, a separate post-treatment facility that only treats ozone is required.

Moreover, the above-mentioned electric dust collector has a problem that it is difficult to carry, since it is large in size and has a relatively heavy weight.

Accordingly, there is a need for a technology for a wearable air purifier capable of solving the problems according to the prior art mentioned above.

Prior to this, terms or words used in the specification and claims should not be construed as being limited to a conventional or dictionary meaning, but should be interpreted as meanings and concepts consistent with the technical idea of the present invention.

Throughout this specification, when a member is said to be located "on" another member, this includes not only the case where the member is in contact with the other member, but also the case where another member exists between the two members. Throughout this specification, when a certain part "includes" a certain component, it means that other components may be further included rather than excluding other components unless otherwise stated.

Referring to these drawings, the wearable air purifier 100 according to the present embodiment is a wearable air purifier that is worn on a part of the wearer's face or head to provide purified air to the wearer's respirator, and has a specific structure. By providing 110, the air intake unit 120, the ion generating unit 130, and the purified air supply unit 140, the dust contained in the air is effectively removed by using the ion generating unit in which ozone is not generated, so that the wearer is more comfortable. It is possible to provide a wearable air purifier that can provide cleaner air.

Before explaining the ion generating device according to an embodiment of the present invention, a corona discharge, which is the principle of ion generation, will be described. Gas molecules that are electrically destroyed due to electrical destruction of gas molecules in the vicinity of the electrodes connected with high voltage emit electrons. . Free electrons generated by the emission of electrons from the gas are affected by a strong electric field formed around the electrode.

Free electrons have very large energy in a strong electric field and move at a high speed, collide with molecules in the air, or move to places where there is no electric field influence by corona discharge. Corona discharge can be divided into positive corona discharge and negative corona discharge according to the polarity of the discharge electrode.

2 is a view showing an ion generating device in which cathode corona discharge is generated, and the wearable air purifier according to an embodiment of the present invention is not limited to a device using cathode corona discharge.

However, in the case of the positive corona, the polarities of the first electrode 30 and the second electrode 40 are the same, except for the first electrode 30 including the discharge needle 31 and the second electrode 40 to which a high voltage is applied. It may further include a ground electrode.

As shown in FIG. 2, a strong electric field around the first electrode 30 accelerates free electrons existing in the gas. The accelerated free electrons move at a high speed and collide with other molecules, and the collided molecules become positive ions and release one more free electron. These free electrons collide with gas molecules in a chain to generate a large number of positive ions and free electrons. Such an ion increase process is called avalanche multiplication. This multiplication phenomenon continues as long as the high-speed accelerating electrons collide with gas molecules to generate ions, and are determined by the electric field strength (E).

As the multiplication phenomenon occurs in a chain in the ionization region shown in FIG. 2, the generated free electrons form a flow of electron groups toward the dust collecting part along the electric field.

When free electrons forming an electron group are out of the ionization region, that is, the corona discharge range, they reach the interpole region. In the interstitial region, since the electric field strength is smaller than that in the corona region, the velocity of free electrons rapidly decreases. Even if electrons collide with gas molecules in the interstitial region, it is impossible to ionize gas molecules because it is impossible to maintain a speed sufficient to ionize gas molecules as in the corona region. Therefore, free electrons are adsorbed on the surface of gas molecules to make gas molecules with anions as shown in FIG. 2, and gas molecules with anions collide with and adsorb to dust particles in the air, thereby electrically charging the dust. The electrically charged dust particles move to the second electrode 200 to which a high voltage is applied and accumulate. That is, when the ion generating device according to the embodiment of the present invention is applied to a dust collector, the second electrode 40 may be a dust collecting plate.

Hereinafter, each component of the wearable air purifier 100 according to the present embodiment will be described in detail with reference to the drawings.

General metal oxides have both metallic and insulating properties depending on the oxygen vacancy in the oxide. When the vacancy of oxygen atoms is largely distributed in the metal oxide, the metal oxide has a conduction property close to that of the metal, and when the vacancy of the oxygen atom is less distributed in the metal oxide, the metal oxide has a property close to that of an insulator. The vacancy of the oxygen atom varies depending on the type and temperature of the metals that make up the material.
