The coupling protrusion 51 and the coupling groove portion 35 may be further provided with small protrusions/grooves so as to more firmly maintain the coupling state, and may be further engaged by press fitting so as not to be easily separated.

As an example, the shade member 50 may be composed of two unit members 50 ′ and 50 ″.

In this case, the first unit member 50 ′ is formed to extend outwardly from the annular first coupling protrusion 51 ′ inserted into the coupling groove portion 35 and the first coupling protrusion 51 ′. It includes a first shade portion 53 ′ constituting a part of the shade portion 53.

In addition, the first coupling protrusion 51 ′ can be rotated while being inserted into the coupling groove 35, and the second coupling protrusion 51 ″ is the first coupling protrusion 51 ′. ) Is configured to be able to rotate in the state of being inserted into the inner side.

In addition, the rotational central axis (A3) in which the rotation of the first engaging protrusion 51 ′ and the second engaging protrusion 51 ″ is performed is a direction perpendicular to the hinge central axis A2 of the hinge engaging unit 32 Is placed as.

Through the above configuration, according to the position rotated in the state in which the second coupling protrusion 51 ″ is inserted into the inner side of the first coupling protrusion 51 ′, the second shaft-shaped portion 53 ″ And a region and a location of the first hat-shaped portion 53 ′ surrounding the exposure hole 33 of the body portion 30 may be changed.

State), when the first and second caps 53 ′ and 53 ″ are rotated to the positions where they are completely overlapped, the circumference of the exposure hole 33 may be wrapped in an arc range of 180° ( 4(b) state), when the first and second caps 53 ′ and 53 ″ are rotated to the overlapping position by a 90° arc range, the periphery of the exposure hole 33 Can be wrapped in an arc range of 270° (intermediate state of (a) and (b) of FIG. 4).

6 is a side view showing a state of use of the fine dust removing apparatus according to an embodiment of the present invention.

As shown in FIG. 1, the device for removing fine dust of this embodiment includes at least one upper body part 20 and a body part 30 installed on a rail 10 attached to the interior ceiling of a building, and the body part 30 The negative ion generator 40 in which the fiber 42 is installed is installed, and a shade member 50 is installed outside the main body 30.

In consideration of the amount of fine dust generated, the number of the upper body portion 20 and the body portion 30 may be appropriately increased or decreased.

When power is turned on so that the electrode pieces 22 are in contact with the electrode unit 16 while power is applied to the rail 10, power is supplied to the negative ion generator 40 of the body unit 30 installed on the rail. It is supplied and the negative ions generated by the negative ion generating circuit provided inside the negative ion generator 40 are discharged to the indoor space of the building through the metal fiber 42, so that fine dust in the room can be removed.

In more detail, fine dust particles in the air suspended in the form of cationic particles around the metal fiber 42 are adsorbed and cured by anions to form larger particles. When fine dust particles are adsorbed and their size becomes as large as ordinary dust particles, the particles are precipitated on the indoor floor by the load of the particles and fine dust particles floating in the air are precipitated and removed to the floor.

During this process, since fine dust adjacent to the lower tip of the metal fiber 42 first contacts negative ions at a close distance, adsorption hardening occurs preferentially compared to fine dust located in the lower space, and particle size is preferred. Becomes larger.

However, there is a concern that some of the dust particles undergoing adsorption and hardening may float in the air and rise to the ceiling surface where the fine dust removal device is installed, adsorbing, and cause a blackening phenomenon that makes the ceiling black. The removal device guides the floating dust particles to stay around the metal fibers 42 without rising directly to the ceiling surface by the shaft-shaped member 50 surrounding the outside of the metal fibers 42, so that the adsorption hardening phenomenon is more smooth. You can induce it to happen.

On the other hand, in consideration of the indoor environment and the efficiency of removing fine dust, the main body 30 may be installed downward as shown in Fig. 6(a), and the main body 30 may be installed as shown in Fig. 6(b). It can also be installed by adjusting the orientation and angle so that it rotates laterally at a certain angle around the hinge central axis A2.

The fine dust removing apparatus of this embodiment considers the installation direction of the main body 30, and when the main body 30 is installed downward as shown in Fig. 6(a), the first shade-shaped part 53' ) And the second shade portion 53'' to be rotated to a position that does not overlap each other so that the periphery of the exposure hole 33 can be wrapped in an arc of 360° (Fig. 4 (a) state), and adsorption Prevents some of the dust particles being cured from escaping to the outside of the shade.

In addition, as shown in (b) of FIG. 6, when the main body part 30 is rotated in a lateral direction with a certain angle around the hinge center axis A2, the first and second shafts 53' By rotating the part 53'' to a position where it is completely or partially overlapped, it partially wraps around the exposed hole 33, but the surrounding position is wrapped around the upper side of the metal fiber 42 (Fig. 4(b)) State), prevents some of the dust particles undergoing adsorption and curing from escaping to the outside of the lampshade. In addition, in this case, the metal fiber 42 may smoothly contact the fine dust particles in the exposed portion without the shade part. EG of FIG. 6 illustrates the flow of dust particles.

7 is a perspective view of a hat-shaped member of an apparatus for removing fine dust according to another embodiment of the present invention.

As a modified example, as illustrated in FIG. 7, any one of the first shade portion 53 ′ and the second shade portion 53 ″ is shaded from the other shade member 50. It may be further extended to increase the height of the.

For example, as shown in (b) of FIG. 6, when the main body 30 is rotated laterally at a certain angle around the hinge central axis A2, the first shaft 53' and the The second shade portion 53 ″ may be rotated to a position completely or partially overlapped to partially wrap around the exposure hole 33, but the surrounding position may be wrapped around the outer upper side of the metal fiber 42.

In this case, when the shade-shaped portion 55 further expanded in the shade-shaped member 50 of the embodiment of FIG. 7 surrounds the outer upper side of the metal fiber 42, some of the dust particles undergoing adsorption and curing It can be more effectively prevented from rising to the outside.

8 is a perspective view of a hat-shaped member of an apparatus for removing fine dust according to another embodiment of the present invention.

As a modified example, the hat-shaped member 50 may be integrally formed as one member, as illustrated in FIG. 8.

In this case, preferably, the hat-shaped portion 153 is further expanded so that the height of the hat of one side 153b is higher than that of the hat of the other portion 153a.

In the case of the embodiment of FIG. 8, for example, when the shade-shaped portion 153b formed further expands in the use state as shown in FIG. 6(b) to surround the outer upper side of the metal fiber 42, dust undergoing adsorption hardening It is possible to more effectively prevent some of the particles from leaving and rising to the outside of the shade-shaped portion.
