For this reason, purified air and moisture are supplied to the user at the same time to provide a comfortable environment, and the area occupied by the room is reduced, so that it can be conveniently used without restriction of place, thereby increasing portability.

Interest in the air quality of the indoor environment, where most of our time is spent, is growing, and its importance is also being emphasized.

Factors that determine indoor air quality (IAQ) include humidity and concentration of harmful substances.

In particular, there is a problem in that it is difficult to control moisture and control the concentration of harmful substances for a comfortable environment in offices or places where many people live in enclosed spaces. It is preferable to use a portable air cleaning device.

In addition, while the interest in air quality is emphasized even in the dry season, the use of a humidifier that can prevent respiratory disorders and diseases is recommended by maintaining a suitable humidity to maintain a comfortable state in a dry place.

In general, a humidifier is a device that sucks dry air into the inside by using a blower and discharges a lot of humid air. Recently, more functions have been added, and air purifiers with humidification functions, negative ions and oxygen supply functions are also on the market.

However, the above humidifiers and air purifiers are mainly of the stationary type installed in a room or office, and only purify the indoor air. there is a problem.

In addition, since the air cleaning device and the humidifying device must be separately provided, the purchase cost is high, and the occupied space is large, so there is a problem in inconvenient maintenance.

Therefore, there is an urgent need to supply a device that does not restrict activities by supplying clean air and humidified air corresponding to the humidity and the concentration of harmful substances required for each individual that can solve the above problems.

The filter unit may include a porous adsorbent. The porous adsorbent may have an effect of purifying air by adsorbing odors and other harmful chemical gases. In addition, it can have the effect of improving air quality by adsorbing fine dust.

According to FIG. 3 , the filtration unit 130 is included as one configuration of the purification unit 100 , and is composed of a first filtration unit and a second filtration unit so that air passes through the first filtration unit and passes through the second filtration unit. is configured to

The first filtering unit and the second filtering unit are configured as filters, so that impurities having large particles may be removed by the filter.

That is, the filter unit 130 is configured with a plurality of filters so that air passes through the plurality of filters, and fine dust in the air that is not filtered by the first filter can be removed while passing through the second filter. .

In addition, the present invention is characterized in that it contains a porous adsorbent.

The porous adsorbent is attached to one surface of the filter unit 130, which is the filter, to enhance the chemical purification effect of the air passing through the filter unit 130 and the fine dust removal effect.

The porous adsorbent is characterized in that it is attached to one surface of the filter, and more specifically, the porous adsorbent is attached to the back surface of the first filter and the second filter.

The first filter and the second filter to which the porous adsorbent is attached to one surface constitute the filtering unit 130 .

At this time, the first filter is a filter through which the flow of air passing through the filtering unit 130 first passes, at this time, the first filter is based on the flow direction of the air, and the first filter is based on the flow direction of the air. The filter side to which the porous adsorbent is not attached is positioned so that the air flow is not obstructed as much as possible and passes through the filter.

The air passing through the filter passes through the surface of the first filter to which the porous adsorbent is attached, thereby increasing the air purification effect.

Thereafter, the air that has passed through the first filter flows to the second filter, and the second filter has a surface to which the porous adsorbent is attached based on the flow of air, so that the air that has passed through the first filter flows through the second filter. of the porous adsorbent passes through the attached surface.

While the air that has passed through the first filter directly comes into contact with the porous adsorption surface of the second filter, the well-known purification effect can be further enhanced.

A first porous adsorbent having an average diameter of 3 to 9 μm is attached to one surface of the first filter, and a second porous adsorbent having an average diameter of 1 to 3 μm is attached to one surface of the second filter.

Preferably, the first porous adsorbent is activated carbon powder having an average diameter of 5 to 9 μm and an oil absorption of 300 to 500 m 2 /g, and the second porous adsorbent is 1 to 3 μm and an oil absorption. is 150 to 300 m 2 /g and may be fine powder silica.

More preferably, the second porous adsorbent is fine powder silica having an oil absorption of 150 to 300 m 2 /g and 1 to 3 μm and a wax having an oil absorption of 150 to 300 m 2 /g. The furnace surface-coated fine powder silica may be included in a weight ratio of 1:1.

The fine powder silica whose surface is coated with the wax is coated with wax and does not show an air purifying effect when used as a filter for the first time. At this time, the air purification effect is shown through the fine powder silica contained in the same weight ratio, and as the wax coating is peeled off over time, the air purification effect of the fine powder silica increases.

That is, compared to the conventional filter, the air purification effect of the fine powder silica can be maintained for a long time, so that the replacement time of the filter can be delayed.

The first porous adsorbent should use activated carbon powder having a relatively large average diameter and large oil absorption in order to minimize air flow prevention. In the case of having the activated carbon powder having an average diameter within the above range, it is possible to minimize the obstruction of the air flow and increase the air purification effect.

In addition, as the amount of oil absorption is used within a specific range, the effect of reducing odors and harmful gases may be enhanced.

The second porous adsorbent uses a porous adsorbent having a relatively small average diameter, which may cause clogging of pores when attached to a filter. Occurs.

In addition, the fine powder silica of the present invention may be coated with wax to enhance the air purification effect.

Experimental example

Confirmation of fine dust and chemical adsorption effect

For the ease of the experiment, the filtration unit was used as a transparent tube, and after attaching the filters S1 to S12 at both ends of the transparent tube, respectively, the air purification effect was confirmed.

As a comparative example, the first filter and the second filter were positioned in the filtration unit, and the porous adsorbent was not attached to one surface of the first filter and the second filter, respectively.

One side of the transparent tube is completely sealed, and a pollutant mixed with a microcell (diameter less than 1 μm) and ammonia is put in from the other side of the transparent tube, and after about 30 minutes, air is collected from the other side of the transparent tube and the fine dust contained and ammonia contents were measured.

As a comparative example, the experimental result of a transparent tube having only an activated carbon filter was set to an index of 5, and the air purification effect of S1 to S12 was relatively confirmed.

(Unit: Index) According to the experimental results, it was confirmed that a specific activated carbon powder and fine powder silica were used to have a better air purification effect compared to the comparative example.

In particular, when the filter of S9 was combined to form a filtration unit, the best air purification effect was exhibited.
