As shown in fig. 1 to 5, the structure of the dust-proof environment-friendly electric fan according to an embodiment of the present invention includes: the motor (100), a rear protection net (220) on which the motor (100) is mounted, a front protection net (240) detachably coupled in front of the rear protection net (220), and a blower fan (300) disposed in front of the front protection net (240) and the rear protection net (220) and coupled to a shaft of the motor (100).

The motor (100) is combined with a motor casing, the motor casing is formed by hinging a rack (140) so as to be convenient for adjusting the angle, a bracket (not shown) is arranged at the lower part of the rack (140), and various switches are arranged on the bracket. The bracket is well known in the art and therefore will not be described in detail.

The blower fan (300) includes a hub (320) coupled to a shaft of the motor (100) and a plurality of blades (340) disposed on an outer circumferential surface of the hub (320).

The hub (320) is cylindrical, and has a through hole at the center thereof for allowing the shaft of the motor (100) to pass through, and a coupling portion (322) on the outer peripheral surface thereof for coupling the wing (340).

the number of the coupling parts (322) is 3 or 4 in proportion to the number of the wings (340).

The wing 340 is made of a material having good air permeability, and has a space formed therein by a plate 342 disposed with upper and lower portions separated from each other, and a clip 344 into which a coupling portion 322 of the hub 320 is inserted is provided.

The wing 340 is a frame (not shown) forming a wing-shaped skeleton by a small-diameter wire or a rod made of bark or bamboo, and is disposed inside, and a plate 342 is disposed to be adhered to the frame so that the upper and lower sides have a certain area and a space is formed inside.

Preferably, the frame is in the shape of a bamboo fan rib, and the plate (342) may be composed of korean paper or hemp cloth having air permeability.

the wing (340) is formed of a plate (342) which may be made of one material selected from a fabric material having fine air permeability, a nylon material, korean paper, and hemp cloth.

The wing (340) is fixed by screwing a clip part (344) through a rear screw to a coupling part (322) of the hub (320). Reinforcing plates may be provided at the portions where the screws (346) are to be screwed.

Therefore, after the screw 346 is separated, the wing 340 can be separated from the hub 320, and when foreign matters such as dust are accumulated on the plate 342 of the wing 340, the wing 340 can be separated and removed and replaced with a new one, thereby maintaining the best performance.

a filter member 348 is disposed at a side end of the vane 340, and is coupled between the upper and lower plate members 342, and is in contact with air to filter out dust.

the filter member 348 is disposed at a position contacting with air in consideration of a rotation direction of the wing 340 disposed at the side end portion, preferably, in consideration of a clockwise rotation of the wing 340 when viewed from the front.

Therefore, air is discharged when the blade (340) rotates, and air flows into the filter member (348) because the filter member (348) is disposed on the side surface in the direction of rotation.

then, the dust, bacteria and particles of peculiar smell are filtered by the filter unit (348), and the indoor air is sterilized and disinfected to purify the indoor air.

The filter member (348) is made of a porous carbon net or a porous metal net having air permeability. The filter member 348 is adhered to the side end of the wing 340 and does not fall off even when rotated at high speed.

In addition, the rear surface of the wing (340) is coated with nano platinum or nano silver photocatalyst to form a photocatalytic layer (342).

The photocatalysis is to decompose harmful substances in the air into harmless substances (H) by receiving light with nanometer (Nano; 10-9m) fine particles to generate strong oxidizing substances (OH free radicals, superoxide) on the particle surface₂0、CO₂、O₂)。

By the decomposition effect of the organic matter, the photocatalysis can be used for the purpose of sterilization and the purpose of removing malodors and harmful substances (VOCS) in the air or water.

the nano platinum or nano silver has strong antibacterial and bactericidal functions, has a bactericidal effect on 650 bacteria and viruses such as coliform bacteria, can be used for prescription, and is used for treating bacterial dermatitis (scalp diseases, ophthalmitis, acne and eczema), infectious diseases (cholera and typhoid fever) and viral diseases (cold and bronchitis) and removing bacterial malodor (armpit, foot and body odor).

The photocatalytic layer (342) is formed after the nano platinum sol or nano silver sol photocatalyst mixed solution or the nano platinum sol or nano silver sol mixed photocatalyst mixed solution is coated and dried on the back surface of the wing (340) (see the enlarged view of fig. 1).

the photocatalytic layer (342) oxidizes, decomposes, and sterilizes organic substances in the air adhering to the wings (340), and reduces the rate at which dust and the like accumulate or adhere to the wings (340).

Further, a light emitting member (240) is coupled to the rear protection net (220) so as to correspond to the rear surface of the wing (340).

The structure of the light emitting part (240) includes: the LED light source comprises a light-transmitting case 241 through which light can pass, a substrate 243 on which an LED 242 which is coupled to the other side of the light-transmitting case 241 and irradiates light to the inside is arranged, an annular plate 247 which is arranged to be connected to a power terminal 246 of the substrate 243 and has a through hole at the center, a reinforcing ring 249 provided on the through hole at the center of the plate, and a reinforcing rib 249 radially arranged on the outer periphery of the reinforcing ring 249.

the light emitting component (240) is assembled on the rear side protection net (220) by penetrating the reinforcing rib (248) and the reinforcing ring (249) to combine the shaft of the motor (100).

the light emitting unit (240) is a terminal of which a power supply terminal is connected to the motor (100) and is energized.

The light irradiated in the light emitting part (240) may then induce a photocatalytic reaction.

The photocatalyst absorbs light and then decreases activation energy by photosynthesis to increase the reaction rate. The photocatalyst can be titanium dioxide mixed with nano platinum or nano silver, and the effect is increased.

the light emitting part (240) is turned on or off in accordance with the switching operation, and can have an air cleaning function and an illumination function.

In addition, a cover member (400) detachably coupled to the front side protective mesh (240) is included.

The cover member (400) includes a plurality of reinforcing bones (420) arranged in a radial shape and a porous carbon mesh or a porous metal mesh (440) adhered to the reinforcing bones (420). A hook ring (450) is arranged on the end of the reinforced bone (420).

The hook ring 450 for reinforcing the bone 420 is fixed to the loop of the front side protection net or can be unhooked.

The porous carbon net or the porous metal net (440) is a metal material having a pore size of 2mm to 5mm through which air or water can pass, and sponge-like metal having a sponge-like structure and plastic having a porosity of 98% at the maximum are deposited with gold, and then heated until reaching a melting point of the plastic, to form plastic microparticles and form a state in which surfaces of the sponge-like metal are common to each other, thereby forming a plurality of pores between the particles.

The material of the expanded metal (440) is copper-nickel alloy or silver or zinc, and the copper and nickel or silver alloy is a material in which 70 to 90 parts by weight of copper, 10 to 30 parts by weight of nickel or silver are mixed.

The copper has a protein-destroying effect according to the common general knowledge, and the bacteria consist of proteins and thus have a sterilizing effect. When nickel or silver is mixed, the effect of killing bacteria in the air can be further improved.

The air blown by the blower fan is filtered by the filter member of the wing and then transferred to the front side protection net by the sterilization action of the nano platinum or the nano silver photocatalyst, and then sterilized again by the cover member.

the cover member (400) is separated from the front protective net (240), and then the porous carbon net or the porous metal net (440) can be cleaned by a mixture (1: 1) of vinegar and water, or water or air, so that the cover member can be regenerated and cleaned conveniently.

also, the aromatic agent container includes an aromatic agent container (500) that is inserted into and combined with the lid member (400).

The aromatic agent containing part (500) is composed of a first cover (511) and a second cover (512) which are provided with a plurality of through holes (502) and can be separated, and a ring-shaped component (520) arranged between the first cover (511) and the second cover (512), and a metal net (530), a porous filter (540) and an aromatic agent bag (560) are contained inside.

therefore, the air passing through the cover member (400) passes through the aromatic agent accommodating portion (500) and is sterilized, and the aromatic agent is diffused, so that the indoor air is comfortable.

the lid member (400) is provided with a coupling through hole (460) at the center thereof for coupling to a second lid (512) of the fragrance storage unit (500).

And a coupling groove 241 for coupling a second cover 512 of the aromatic agent receiving part 500 is also provided at the center of the front side protective net 240.

Therefore, the second cover (512) of the aromatic agent containing part (500) is clamped into the combination through hole (460) of the cover part (400) and the combination groove (241) of the front side protection net (240) to be combined, the ring-shaped component (520) can be supported by the cover part (400) to be combined and fixed, and the aromatic agent containing part (500) can be detached to clean or replace the inside as required.
