The battery status window displays the amount of power remaining in the battery, and the control unit controls the operation speed of the device that induces the flow of air located in the air discharge path according to the remaining power to lower the air flow rate, Make efficient use of power.

If the battery power drops below 10%, the battery status window will blink to add the ability to prompt the user to charge the battery.

The selection button is composed of a general formula and a centralized mode, and can be automatically changed in accordance with the degree of contamination in cooperation with the state of air pollution degree state window. Also, the user can manually operate the air conditioner, It is possible to manually control the flow rate of the air by controlling the operation speed of the apparatus for inducing the flow of the air.

In the case of the general formula, it refers to the effect of a general air purifier, and corresponds to a case in which the flow rate of the air is 'weak', which corresponds to a mode in which the air is normally operated for continuous air management.

In the case of concentrated use, when the intensive management is required, that is, when the pollution degree of the air is high, or when the user's health is bad and the air needs to be purified more intensively than usual, And is operated in a mode (mode).

The power connection portion is configured to be connectable to at least one of a 220V power cord or a USB port capable of supplying power for charging the battery and at least one of the electrostatic precipitator and the air inlet and outlet.

When the battery status window indicates that the power is low, you can either remove the battery and recharge it, or leave the battery in place and connect the power cord or USB port connected to the housing to the power cord or computer to charge the battery It is possible to operate the air purifier and function efficiently.

In addition, a battery room having a battery and a control unit, a cover for lifting the electrostatic precipitator and the filter unit to clean and replace the inside of the housing can be constructed.

According to Fig. 4, it can be seen that a general linear magnetic field is generated between a positive (+) polarity stainless steel plate and a negative (-) polarity stainless steel plate.

However, according to FIG. 5, it can be seen that a stainless steel plate having a plurality of points is concentrated at each apex between a positive (+) polarity stainless steel plate and a negative (-) polarity stainless steel plate to form a curved magnetic field .

When such a configuration is taken, the electric field density increases at the tangent point and the corona discharge is more likely to occur.

Since the portable air purifier which can be used on a tabletop and which extends the air retention time of the present invention is miniaturized, the width of the ionized portion is narrow to about 3 cm. Therefore, some dust is not positively charged, do.

However, when the tie point is provided, the corona discharge occurs well between the discharge electrode and the end of the stainless steel plate, so that the density of the magnetic field becomes larger than when the tie plate is flat.

In addition, if the surface area of the stainless steel plate of the dust collecting part is constituted by a cusp, the dust collecting part itself can act as an ionizing part as well as the dust collecting part.

If some dust not charged in the ionization part enters the dust collection part, it can be positively charged in the dust collection part and can be collected on the stainless steel plate, so that the dust can be effectively collected.

FIG. 6 is a view showing a shape of an air passage of an air purifier in which an air retention time is extended according to a preferred embodiment of the present invention.

Even if the dust is positively charged in the ionizing part, dust may not stick to the dust collecting part if the time passing through the dust collecting part is short.

In order to solve this problem, it is possible to reduce the amount of dust escaping and increase the dust collecting effect by increasing the air retention time.

Although not shown, in addition to a plurality of bending portions bent in a left and right direction in a plan view, the bending path can be set three-dimensionally or three-dimensionally in the same direction as the upper, lower, left, and right directions, so that the inner space of the limited air cleaner can be used more efficiently.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. It is to be understood that various modifications and changes may be made without departing from the scope of the appended claims.
