This rounding shape can also have the effect of reducing air friction in the process of the upward air flow inside the housing.

In addition, activated carbon in a cylindrical shape that is installed in a structure detachable from the lowermost bottom lid 301 in the inner lower part of the housing 300 to filter and purify the internal air polluted in the enclosed space introduced into the plurality of suction ports 380 / A HEPA filter module 310 is installed. In this case, the activated carbon filter can perform a function of adsorbing and removing cigarette smoke, volatile organic compounds, and other odorous substances as a deodorizing filter of coal or coconut shell. In other words, it is a method of filtering through air to remove fine dust and clean air. Generally, after primary filtration using a pre-filter, fine dust removal through a HEPA filter, and finally harmful dust through an activated carbon filter gas is being processed.

Generally. Such a HEPA filter is a device for removing fine dust, and there are a filter type and an electrostatic precipitation type. In the present invention, a HEPA filter method that can filter 99.7% of particles with a size of 0.3 μm in the air is adopted.

In addition, the suction port 380 has a fitting groove 302b coupled to the fitting member 301a protruding from the floor in the L-shape of a national flag having a predetermined height, and the fitting of the bottom edge of the housing 300 is provided. By protruding downward in a shape corresponding to a position capable of being fastened to the member 301a, a plurality of suction ports 380 in the shape of a straight slit opened when the bottom lid 301 and the housing lower 302 are fastened can be formed. In the present invention, as shown, the suction port 380 for sucking the contaminated air into the purifier is not artificially formed separately, but is naturally solved through a detachable assembly structure.

On the other hand, the PCB control module 320 is installed on the upper part of the filter module 310, and it is fixed to the upper surface of the cylindrical structure formed at the center of the inner part and turns on/off the electric signal for performing the heating function of the planar heating element when air is sucked.

In addition, the planar heating element module 340 constitutes an electric signal output unit 340a connected to an electric signal input terminal formed on the upper surface of the PCB substrate on which the PCB control module is formed in the center of one end, and an external power supply is located in the center of one side of the upper surface of the substrate By forming an electrical signal input unit 321 capable of applying , a heating function according to external electricity application is performed.

In this case, it is preferable that the input unit 321 allows a portable device that is easy to access and use rather than a separate external electric wire lead-in. To this end, in the present invention, the USB port 321 is installed in the center of the upper surface of one side of the PCB board, and a straight-shaped slit groove 321a is provided in the corresponding external housing position so that power can be easily applied from the outside. .

In addition, the control module 320 constitutes an air intake fan 330 installed to easily inhale external air generated from inside the vehicle or indoors, and the fan 330 is the PCB control module. An electric signal is received from the 320 to enable selective operation, and the built-in fan 330 is driven so that air flows into the housing through the inlet 380 and then is discharged to the outside through the outlet 390 . Allow air to flow.

In this case, the air intake fan 330 is installed in a size and position suitable for the structure of the cylindrical housing 300 opened downward, and is driven into an enclosed inner space to maximize the power of the fan 330 operation. It is desirable to ensure that the wind pressure is transmitted intact.

In this case, the motor 330b for driving the fan 330 is more preferably a BLDC motor using an inverter circuit instead of a brush in order to solve the brush wear and noise problems of the DC motor that are widely used in the past.

On the other hand, the upper surface of the control module 320 and the inside of the housing 300, the vertical support 341 having a plurality of predetermined projections 341a in the height direction of the vertical support 341 with 360 degrees surrounding the inside of the carbon fiber planar heating element module ( 340) is installed, and in this case, the planar heating element 343 is preferably attached in a shape to surround the inside of the vertical support 341 so that heat is transmitted completely in a radial direction.

At this time, the fixing of the planar heating element 343 is attached to the metal member 341b having a predetermined height to the lower inner surface of the vertical support 341. When the heating element 343 surrounds the support 341, a plurality of magnets 343a are embedded in the lower end of one end of the planar heating element 343 corresponding to the position corresponding to the magnetic force between the magnet 343a and the metal member.

In general, carbon constituting carbon fiber is mainly inorganic or organic graphite structure, and in its form, it can be roughly divided into carbon fiber made of thread, powder made of powder, carbon felt made like cotton, and carbon rod made of solidification. However, in the present invention, a planar structure made of threads is adopted to facilitate the structural application of the upward airflow into the housing, thereby obtaining a desired heating effect.

And, as described above, carbon fiber, which is a form of carbon, is classified into polyacrylonitrile (PAN)-based, pitch-based, and rayon-based depending on the raw material thereof, and PAN-based and rayon-based materials occupy most of them. Among the carbon fibers described above, PAN-based carbon fibers are made by calcining PAN at a temperature of 1,000 to 2,000° C. or higher under an inert gas. On the other hand, in the case of the pitch system, the pitch from coal is fiberized and completed through almost the same process as the PAN system, but it is widely used as a high-temperature insulation material or reinforcing material because it is cheaper than the PAN system.

In the center of one end of the planar heating element made of carbon material having the excellent heating characteristics, the heating function is started by configuring the electric signal output unit 340a connected with a wire so as to be electrically connected to one terminal of the control module.
