Description

Air cleaning cartridge applicable to fan

The present invention relates to an air cleaning cartridge applicable to a fan, and more particularly, by replacing the head of an existing fan with an air cleaning cartridge, so that an air cleaning effect can be obtained using rotational force generated through the motor of the fan. And, it can be applied to all existing fans of various sizes and shapes, and it allows the air introduced from the rear side to flow out to the front side, thereby generating an air purification effect while maintaining the original function of the fan, or It relates to an air cleaning cartridge applicable to an electric fan, which does not maintain the original function of the fan and generates only an air purification effect, such as flowing upward.

Dust refers to particulate matter that floats or blows down in the air, and is often generated from burning fossil fuels such as coal and petroleum, or from exhaust gases such as factories and automobiles.

Dust can be classified into total dust (TSP, Total Suspended Particles) of 50㎛ or less and fine dust (PM, Particulate Matter) having a very small particle size according to the size of the particles, and the fine dust is again smaller than 10㎛ in diameter. It can be divided into fine dust (PM ₁₀ ) and fine dust (PM _2.5 ) whose diameter is smaller than _2.5 μm.

Because fine dust is so small that it is invisible, it stays in the atmosphere and then penetrates the lungs through the respiratory tract or moves into the body along the blood vessels, which adversely affects the human body. For this reason, the World Health Organization (WHO) has been suggesting air quality guidelines for fine dust (PM10, PM2.5), and the International Agency for Research on Cancer (IARC) under the World Health Organization Dust has been designated as Group 1 carcinogens that cause cancer in humans (Group 1).

It is believed that humans are living with an average of 10 times more air than food and water consumed a day.If the air quality in the indoor space where humans stay is poor, a large amount of fine dust is generated through breathing. The demand for air purifiers to improve indoor air quality is increasing year by year, since it may flow into the air and cause health problems.

Air purifiers can be classified into mechanical, wet, and complex types according to air cleaning methods.

The mechanical type is further divided into a filter type (dry type) and an electric type, and the filter type includes a dust collection filter type that removes dust using a pretreatment and a HEPA filter, and an electric type that adsorbs harmful gases using activated carbon.

The wet type is an electric dust collection type that charges dust using a high voltage and attaches it to a current collector plate to remove it, an anion type that generates anions at a high voltage and supplies them into the air, and a plasma type that removes harmful gases by generating positive and negative ions with plasma. , It can be divided into UV photocatalysts that remove odors and harmful gases by oxidation-reduction of OH radicals and active oxygen generated when UV rays are irradiated to TiO.

The complex type refers to a method of purifying air by combining functions such as a mechanical type and an electric type.

Although the effect of using an air purifier cannot be denied, there is no choice but to incur a cost to purchase such an air purifier, and the higher the performance or function of the air purifier, the more expenditure is required. Purchasing an air purifier would not be very difficult if there was an economic margin, but it would be difficult for vulnerable social groups who do not have an economic margin to purchase such an air purifier, so they could only rely on natural ventilation. It is true that their health is greatly threatened as they become bad.

Recognizing this problem, efforts have been made to purify the indoor air using wind generated by the fan by additionally installing a filtering means to the existing fan without purchasing a separate air purifier product.

According to the prior art shown in Fig. 1, the head shape of the fan (F) If this is different, the size and shape of the air purifying mechanism 90 for a fan mounted on the head of the fan F must also be changed.

If the size and shape of the fan air purifying mechanism 90 cannot be configured to be similar to the shape of the fan (F) head, the fan air purifying mechanism 90 cannot sufficiently cover the head of the fan (F). , A space spaced apart between the fan (F) head and the air purifying mechanism 90 is inevitable, and unpurified air is inevitably discharged into the room through such a space.

In addition, if the shape between the fan (F) head and the air purifying device 90 does not exactly match, the fixing between the fan (F) head and the air purifying device 90 becomes difficult, and thus the air purifying device ( There may be a problem that the 90 is separated from the fan (F).
