In one example, the air purification device 10 may be connected to the roof of the bus.

Here, as an example, the air purification device 10 is connected to the mobile body, forms a placement space (S), and the inlets (H1, H3) and the arrangement of air to flow into the placement space (S) from the outside It may include a case 100 forming the outlet (H2, H4) through which air flows out from the space (S).

For example, the case 100 may be a configuration that protects components such as the movement changer 200 to be described below from an external environment.

In one example, the case 100 may be detached from the moving body by a connecting member (not shown) such as a bracket or a bolt.

As an example, the case 100 may include a body part 110 forming the placement space S, and cover parts 120 and 130 covering the placement space S.

In one example, the body portion 110 may be in the form of a tube forming a hollow.

For example, the cover parts 120 and 130 include a first cover part 120 detachably attached to one side of the main body part 110 and a second cover part 130 detachably attached to the other side of the main body part 110. It can be provided.

For example, the first cover part 120 may form the inlets H1 and H3, and the second cover part 130 may form the outlets H2 and H4.

Furthermore, each of the first cover part 120 and the second cover part 130 includes a first fixing part 140 and a purification part 300 capable of fixing the movement change part 200 to be described below. A second fixing part 150 that can be fixed may be provided.

Here, as an example, the air purification device 10 is disposed on the arrangement space (S), and further includes a movement change unit 200 for changing the movement direction of the air introduced from the outside to the arrangement space (S) It can contain.

In one example, the movement change unit 200 is disposed on the arrangement space (S), the flow of air flowing into the arrangement space (S) from the outside through the inlets (H1, H3) according to the movement of the mobile body It may be a configuration that changes direction.

Here, as an example, the air purification apparatus 10 is further disposed on the arrangement space (S), further comprising a purification unit 300 for purifying the air in which the movement direction is changed by the movement change unit 200 Can.

For example, the purification unit 300 may be a purification filter disposed on the arrangement space S to purify air whose movement direction is changed by the movement change unit 200.

In one example, the purification unit 300 may be made of fibers, paper, synthetic resin, and the like forming fine pores.

That is, as the air passing through the purification unit 300 passes through the purification unit 300, fine dust may be caught in the purification unit 300.

That is, the air introduced into the arrangement space S by the movement of the moving body is changed in the direction in which the purification unit 300 is disposed by the movement changing unit 200 so that the purification unit 300 As it passes, the fine dust is filtered as it passes through the purification unit 300, and may be discharged to the outside through the outlets H2 and H4.

Here, as an example, the purification unit 300 may surround the movement changing unit 200.

In one example, the purification unit 300 may surround the circumference of the movement change unit 200 disposed in the arrangement space (S).

For example, the purification unit 300 may have a hollow tube shape.

As a result, the air whose direction of movement has been changed by the movement changing unit 200 may pass through the purification unit 300 disposed around the movement changing unit 200, and a passing area may be large.

Therefore, purification can be implemented for a lot of air.

Here, as an example, the movement changing part 200 may be provided on the rotating shaft 210 and the blade 220 formed on the rotating shaft 210 and rotated by the movement of air.

For example, the air introduced into the arrangement space S due to the movement of the moving object may strike the wing part 220 and the movement direction may be changed to the purification part 300 direction.

The wing part 220 may be rotated by the resistance of air, and as a result, the rotation shaft 210 may be rotated clockwise and/or counterclockwise.

For example, a plurality of wing parts 220 may be formed on the rotation shaft 210.

For example, one side of the rotating shaft 210 may be detachable from the first fixing portion 140 formed on the first cover portion 120, and the other side of the rotating shaft 210 may be the second cover portion 130 ) Can be attached to and detached from the first fixing part 140.

The rotation shaft 210 is positioned at a predetermined position on the arrangement space S by the first fixing part 140, and may be rotated on the first fixing part 140.

For example, the purification unit 300 may be disposed in the arrangement space S to surround the wing unit 220 around the wing unit 220 based on the rotation shaft 210.

As a result, the arrangement space S is an inner arrangement space S formed inside the purification portion 300 and an outer arrangement formed outside the purification portion 300 based on the purification portion 300. It can be divided into space (S).

For example, one side of the purification part 300 may be detachable from the second fixing part 150 formed on the first cover part 120, and the other side of the purification part 300 may be the second cover part. It can be attached to and detached from the second fixing part 150 formed in 130.

When it is necessary to replace the purification unit 300, an operator separates the first cover unit 120 from the main body unit 110 and externally removes the purification unit 300 located on the arrangement space S. Can be easily separated.

Here, as an example, the first cover portion 120 is the first inlet (H1) to allow air to flow into the inner arrangement space (S) from the outside and the air to flow into the outer arrangement space (S) from the outside. To form a second inlet (H3).

In more detail, the first inlet H1 is formed at a position communicating with the inner arrangement space S, and the air passing through the first inlet H1 from the outside is the movement changer 200. It may be introduced into the inner arrangement space (S) is disposed, the second inlet (H3) is formed in a position communicating with the outer arrangement space (S), passing through the second inlet (H3) from the outside The air to be introduced may be introduced into the outer arrangement space S in which the movement change part 200 is not disposed.

As a result, it is introduced into the inner arrangement space (S) through the first inlet (H1) is passed through the purification unit 300 by the movement change unit 200 is moved to the outer arrangement space (S) Air may be moved in the direction of the outlet (H2, H4) without vortex by the flow of air passing through the second inlet (H3) and moved on the outer arrangement space (S).

Here, as an example, the second cover portion 130 is moved on the first outlet (H4) and the outer arrangement space (S) to discharge the air moving on the inner arrangement space (S) to the outside A second outlet port H2 to allow air to be discharged to the outside may be formed.

To explain this in more detail, the first outlet (H4) is formed at a position communicating with the inner arrangement space (S), the air moved on the inner arrangement space (S) passes through the first outlet (H4) By being discharged to the outside, the second outlet (H2) is formed in a position communicating with the outer arrangement space (S), the air moved on the outer arrangement space (S) is the second outlet (H2) It can be discharged to the outside through.

Here, as an example, the movement changing unit 200 may further include a weight adjusting unit 230 that controls the degree of rotation of the rotating shaft 210 by applying weight to the rotating shaft 210.

If, when the moving body is moving at a high speed and the speed of air flowing into the arrangement space S is high, the rotating shaft 210 may be rotated at a high speed by the wing part 220, and as a result As the rotating shaft 210 is rotated at an unintended high speed, damage may occur.

To solve this, the weight adjusting unit 230 may adjust the rotational speed of the rotating shaft 210 by applying weight to the rotating shaft 210.

For example, the high-speed rail having a relatively high moving speed may have the weight adjusting unit 230 having a relatively large weight installed on the rotating shaft 210, and the weight having a relatively small weight on a city bus having a relatively slow moving speed. The weight adjusting unit 230 may be installed on the rotating shaft 210.

Therefore, the operator can select the weight of the weight adjusting unit 230 according to the characteristics of the moving body and connect it to the rotating shaft 210.

In one example, the weight adjusting unit 230 may be detachable from the rotating shaft 210.

For example, although not shown in the drawing, the movement changing part 200 further includes a friction adjusting part that applies a friction force to the rotating shaft 210 according to the moving speed of the moving body to adjust the degree of rotation of the rotating shaft 210. You may.

For example, the friction adjusting unit may adjust the degree of rotation of the rotating shaft 210 by applying frictional force to the rotating shaft 210 in the same and/or similar manner to the friction pad of the brake.

In one example, the friction adjusting unit corresponds to the moving speed of the moving body that is changed from time to time, and if the moving body is moved at a relatively high speed, relatively large friction is applied to the rotating shaft 210, and the moving body is relatively When moving at a slow speed, relatively little friction and/or friction may not be applied to the rotating shaft 210.

For example, the friction adjustment unit may be driven electronically and mechanically by a control unit that senses the speed of the moving body and adjusts the degree of friction of the friction adjustment unit.

In addition, although not shown in the drawing, the air purification device 10 may further include a power generation unit that generates electric power by rotation of the rotation shaft 210.

For example, the power generation unit may be configured to convert rotational kinetic energy of the rotating shaft 210 into electrical energy.

For example, the power generation unit may be a device that converts heat energy generated by rotational motion on the first fixing unit 140 into electrical energy.

Further, the power generation unit may be a device that converts rotational motion of the rotating shaft 210 into electrical energy, such as wind power generation.

As described above, the air purifying apparatus 10 according to an embodiment of the present invention is connected to the mobile body and moves in connection with the movement of the mobile body, thereby having the advantage of purifying air with no power.

In the above, the configuration and features of the present invention have been described based on the embodiment according to the present invention, but the present invention is not limited to this, and various modifications or changes can be made within the spirit and scope of the present invention. It is apparent to those skilled in the art, and thus, such changes or modifications are found to be within the scope of the appended claims.
