Description

Ultraviolet sterilization device and ultraviolet sterilization method {ULTRAVIOLET STERILIZER AND STERILIZATION METHOD}

The present invention relates to an ultraviolet sterilization device and an ultraviolet sterilization method, and more particularly, to an ultraviolet sterilization device and an ultraviolet sterilization method capable of sterilizing rapidly and effectively at low cost with a simple configuration.

Ultraviolet rays are widely used for low-cost, simple, and rapid sterilization. For example, a commercially available ultraviolet sterilization device is provided with an ultraviolet lamp that sterilizes by irradiating ultraviolet rays.

The ultraviolet sterilization device can be effectively used in spaces where sterilization must be frequently performed, such as livestock sheds, wards in hospitals, operating rooms, passageways, and the like.

However, various devices such as a serving table, a partition wall, an operating table, medical equipment, a ventilator, a lighting device, and a camera may be disposed in the space. Therefore, in order to rapidly and effectively sterilize the entire space, the ultraviolet sterilization device must irradiate ultraviolet rays at various angles at various heights.

Prior art related to an ultraviolet sterilization device capable of changing the height and angle of irradiating ultraviolet rays is as follows.

Korean Patent Registration No. 10-1742447 relates to an ultraviolet sterilization robot, which includes a lamp unit that generates ultraviolet light, a reflection unit that induces a direction change so that ultraviolet light emitted from the lamp unit is unidirectionally emitted, and a body perpendicular to the body. A support portion disposed in the longitudinal direction and rotatable in a vertical direction and a first rotational direction, and a connection portion connecting the ramp portion and the support portion and rotatable in a second rotational direction, wherein the support portion moves in a vertical direction or rotates in the first rotational direction. By doing so, the entire ultraviolet sterilizer can be moved in the vertical direction or rotated in the first rotation direction to concentrate and emit ultraviolet light emitted from the lamp unit in the multi-contact area, thereby providing an intense sterilization effect.

However, in the prior art, since the entire ultraviolet sterilizer rotates in the first rotational direction, the lamp unit cannot irradiate ultraviolet rays toward the side in a state where the lamp unit is inclined in the second rotational direction. Accordingly, the prior art has restrictions on the direction of irradiation of ultraviolet rays.

In addition, in the prior art, when the lamp unit is tilted in the second rotational direction, it is difficult to maintain the tilted state and cannot accurately adjust the distance from the object to be sterilized.

Specifically, one side of the cover 150 may be coupled to the rotational support 200 and the other side may be coupled to the neighboring rotational support 200 as shown in the drawing or, unlike the drawing, coupled to the base portion 100. there is. Thus, even if a large pressure is applied to the rotation support unit 200 to support the first rotation unit 300, the second rotation unit 400, and the ultraviolet light emitting unit 500, the cover 150 supports the rotation support unit 200. It is possible to prevent the rotation support 200 from being deformed or the rotation support 200 separated from the base 100.

In addition, the cover 150 surrounds the edge and upper portion of the base portion 100, and the coupling portion of the base portion 100 and the rotation support portion 200, the coupling portion of the rotation support portion 200 and the first rotation portion 300, and Various cables connected to the UV light emitting unit 500 may be protected by preventing them from being exposed to the outside.

Referring to FIGS. 8 and 9 , each UV light emitting unit 500 rotates the base unit 100 via the rotation support units 200a and 200b, the first rotation units 300a and 300b, and the second rotation unit 400. It can be rotatably coupled to. Let's look at each configuration.

[base part]

The base part 100 may have a plate shape and may be installed above the lifting part 700 described above. For example, the base part 100 may be installed above the lift column 700a.

Base portion 100 may be formed with a through hole (T) that penetrates vertically on one side.

The through hole T may communicate with the cable pipe 700b. Thus, the power cable or data cable passing through the inside of the cable pipe 700b may be connected to the ultraviolet light emitting unit 500 disposed on the upper part of the base unit 100 through the through hole T.

In addition, the base portion 100 may define a base surface. The base surface may refer to a virtual plane of the surface of the base part 100 .

[rotation support]

The rotation support unit 200 may be coupled to the base unit 100 and the first rotation unit 300 . The rotation support unit 200 may support the first rotation unit 300 so that the first rotation unit 300 is rotatable on the base unit 100 about the first rotation axis A1. Here, the first rotation shaft A1 may be formed through the rotation support 200 and may extend in a direction substantially parallel to the base surface defined by the base 100 .

In addition, the rotation support 200 may be provided with a first angle adjusting means 210 for adjusting the rotation angle of the first rotation unit 300 with respect to the rotation support 200 .

For example, the rotation support facing the first side (S1 ') of the rotation support 200 facing the one side (S1) of the first rotation unit 300 or the other side (S2) of the first rotation unit 300 ( 200) may be provided with first angle adjusting means (210a, 210b) on the second side (S2').

10 to 13, the first angle adjusting means (210a, 210b) of the rotary support 200 is, for example, circumferentially spaced at a predetermined distance (D1, D2) from the first rotating shaft (A1). It may include one or more first control holes H1a and H1b formed along the.

However, it is not limited to this configuration. Therefore, the first angle adjusting means 210 of the rotation support 200 may include a first protrusion P1 to be described later instead of the first adjusting hole H1.

On the other hand, the first control hole has a first distance D1 and a second distance D2 from the first rotating shaft A1 on the first side S1' and the second side S2' of the rotation support 200. (H1a, H1b) or first protrusions (P1a, P1b) may be formed, respectively.

For example, as shown in the drawing, first control holes H1a and H1b may be formed on the first and second side surfaces S1' and S2' of the rotation support 200, respectively. Also, unlike the drawings, first protrusions P1a and P1b may be formed on the first and second side surfaces S1' and S2' of the rotation support 200, respectively, and the first side surface S1' The first protrusion P1 may be formed on one of the second side surfaces S2' and the first adjusting hole H1 may be formed on the other side.

At this time, the first distance D1 and the second distance D2 may be different from each other. In this regard, it will be described later.

[1st rotating part]

The first rotation unit 300 may be rotatably coupled to the rotation support unit 200 about a first rotation shaft A1 penetrating the rotation support unit 200 . Here, the first rotation axis A1 may extend in a direction substantially parallel to the base surface defined by the base part 100 .

Also, the first rotation unit 300 may be coupled with the second rotation unit 400 .

The first rotation unit 300 rotates around the first rotation axis A1 so that the ultraviolet light emitting unit 500 can irradiate ultraviolet rays at various angles.

That is, when the first rotation unit 300 rotates around the first rotation axis A1, the ultraviolet light emitting unit 500 may be erected with respect to the base unit 100 (FIGS. 10 and 11), or tilted obliquely. It may be (FIGS. 12 and 13) or laid down (FIG. 22). When a plurality of the first rotation unit 300 and the ultraviolet light emitting unit 500 are radially arranged on the base unit 100, the plurality of ultraviolet light emitting units 500 are rotated according to the rotation of the first rotation unit 300. With respect to the base portion 100, it may be erected radially (FIGS. 1, 6, and 7), inclined at an angle (FIG. 2), or laid down (FIG. 3).

In addition, the first rotation unit 300 may support the second rotation unit 400 such that the second rotation unit 400 is rotatable about the second rotation axis A2. Here, the second rotation shaft A2 may be formed to pass through the first rotation unit 300 and may extend in a direction crossing the first rotation shaft A1.

As shown in FIGS. 8 and 9 , the first rotating unit 300 may include a main member 300a and an auxiliary member 300b. The main member 300a may be coupled to the rotation support 200 and the second rotation unit 400 . The auxiliary member 300b may support the second rotation unit 400 and restrict rotation of the second rotation unit 400 . The main member 300a and the auxiliary member 300b may be coupled.

The first rotating unit 300 will be looked at with further reference to FIGS. 14 to 20 .

The first rotation unit 300 may be rotatably coupled to the rotation support unit 200 about a first rotation shaft A1 penetrating the rotation support unit 200 .

In addition, the first rotation unit 300 may include a first angle adjustment means 310 for adjusting a rotation angle of the rotation support unit 200 .

For example, on one side (S1) or the other side (S2) of the main member (300a, FIG. 8, FIG. 9, FIG. 14) of the first rotation unit 300, the first angle adjusting means (310a, 310b, FIG. 16) ) may be provided.

The first angle adjusting means (310a, 310b) of the first rotation unit 300 is, for example, a first protrusion formed at a predetermined distance (D1, D2, FIGS. 19 and 20) from the first rotation axis (A1). (P1a, P1b).

However, it is not limited to this configuration. Accordingly, the first angle adjusting unit 310 of the first rotating unit 300 may include the above-described first adjusting hole H1 instead of the first protrusion P1.

The first protrusion P1 may be inserted into the first adjusting hole H1. That is, as shown in FIGS. 10 to 13 , the first protrusion P1 may be inserted into any one of one or more (five in the drawing) first adjusting holes H1.

When the first protrusion P1 is inserted into the first adjusting hole H1, the first protrusion P1 cannot easily leave the first adjusting hole H1, so that the first rotating part 300 and the ultraviolet light emitting part 500 By rotating with respect to the first rotational axis A1, a specific rotational angle formed with the rotational support 200 can be stably maintained. Here, the specific rotation angle may be determined according to the position of the first adjustment hole H1 formed along the circumferential direction around the first rotation axis A1.

On the other hand, even if the first protrusion P1 is inserted into the first adjusting hole H1, if a considerable amount of force is applied to the first rotating part 300, the first protrusion P1 may escape the first adjusting groove H1. Therefore, the first rotating unit 300 can rotate. When the first rotating part 300 rotates, the first protrusion part P1 can be inserted into the neighboring first adjustment groove H1 in the circumferential direction. Until the first protrusion (P1) leaves the first control groove (H1) and is inserted into the neighboring first control groove (H1) again, the first protrusion (P1) is the side surface (S1, S2) or the side surfaces S1' and S2' of the rotation support 200 may receive pressure (in the drawing, pressure is received by the side surface of the rotation support).

As such, the rotation support 200 and the first rotation unit 300 are provided with first angle adjusting means 210 and 310 for adjusting the rotation angle of the first rotation unit 300 with respect to the rotation support 200, so that ultraviolet rays Since the rotation angle at which the light emitting unit 500 rotates about the first rotational axis A1 is stably maintained, ultraviolet rays can be stably irradiated at various angles with a simple configuration and at low cost. Thus, sterilization can be performed quickly and effectively.

In addition, the first angle adjusting means (210, 310) is located on the side of the rotation support unit (200) or the first rotation unit (300) at a predetermined distance (D1, D2) from the first rotation axis (A1) along the circumferential direction. one or more first control holes (H1) formed; and a first protrusion P1 formed on a side surface of the first rotation unit 300 or the rotation support unit 200 at predetermined distances D1 and D2 from the first rotation axis A1, and the first protrusion ( P1) may be inserted into the first control hole H1. Accordingly, it is possible to configure the first angle adjusting means (210, 310) at low cost with a simple configuration.

Referring further to Figure 21, the first angle adjusting means (210, 310) supports the spring (B1), the ball (B2) connected to one end of the spring (B1), the other end of the spring (B1) and the ball (B2) and It may include a ball plunger (B) configured to include a housing (B3) accommodating the spring (B1).

The ball plunger (B) may be inserted laterally into a hole formed in the first rotation unit 300 or the rotation support unit 200 . A portion of the ball B2 protrudes laterally from the side of the first rotation unit 300 or the rotation support unit 200, and a portion of the protruding ball B2 may correspond to the first protrusion P1 described above. .

As described above, when the first protrusion P1 is out of the first control groove H1, the side surfaces S1 and S2 of the first rotation unit 300 or the side surfaces S1' and S2' of the rotation support unit 200 may be pressured by When the first protrusion P1 receives pressure, the ball B2 may move to the inside of the housing B3, and thus the spring B1 may be elastically deformed. When the ball (B2) or the first protrusion (P1) reaches the front of the first control groove (H1), the spring (B1) can move the ball (B2) to the outside of the housing (B3) by the restoring force, and accordingly The first protrusion P1 may be inserted into the first adjustment groove H1.

In this way, the first angle adjusting means (210, 310) includes a ball plunger (B) configured to include a spring (B1), a ball (B2) and a housing (B3), the ball plunger (B) is a first It is laterally inserted into the hole formed in the rotation part 300 or the rotation support part 200, and a part of the ball B2 protrudes laterally on the side of the first rotation part 300 or the rotation support part 200, and the protruding ball ( Since a part of B2) corresponds to the first protrusion P1, the first angle adjusting means 210, 310 can be configured with a simple configuration and at low cost.

In addition, since the first protrusion P1 elastically deforms the spring B1 and moves inside the housing B3 when the first protrusion P1 comes out of the first control groove H1, the first protrusion P1 ), and the frictional interference occurring between the first rotation unit 300 or the rotation support unit 200 is reduced to prevent the first protrusion unit P1, the first rotation unit 300 and the rotation support unit 200 from being deformed or damaged. Thus, durability can be improved.

On the other hand, on one side (S1) and the other side (S2) of the first rotation unit (300), the first adjustment hole (H1a, H1b) or the first protrusions P1a and P1b may be respectively formed.

For example, as shown in the drawing, first protrusions P1a and P1b may be formed on one side surface S1 and the other side surface S2 of the first rotating part 300, respectively. In addition, unlike the drawings, first control holes H1a and H1b may be formed on one side surface S1 and the other side surface S2 of the first rotating unit 300, respectively, and one side surface S1 and the other side surface ( A first protrusion P1 may be formed in one of S2) and a first adjusting hole H1 may be formed in the other one.

In addition, as described above, a first distance D1 and a second distance D2 from the first rotating shaft A1 are applied to the first side surface S1' and the second side surface S2' of the rotation support unit 200. The first adjustment holes H1a and H1b or the first protrusions P1a and P1b may be respectively formed.

When the first protrusion P1 is formed on one of the side surfaces S1 and S2 of the first rotation unit 300, the side of the rotation support 200 facing the side surface S1 and S2 on which the first protrusion P1 is formed A first control hole H1 may be formed in (S1', S2'), and when the first control hole H1 is formed on either side surface S1 or S2 of the first rotation unit 300, the first control hole H1 is formed. A first protrusion P1 may be formed on the side surfaces S1' and S2' of the rotation support 200 facing the side surfaces S1 and S2 where the adjustment hole H1 is formed.

That is, one side surface S1 of the first rotating unit 300, the first side surface S1′ of the rotation support unit 200, and the other side surface S2 of the first rotation unit 300 and the second side surface S2 of the rotation support unit 200 First adjustment holes H1a and H1b and first protrusions P1a and P1b are formed on the side surface S2' at a first distance D1 and a second distance D2 from the first rotation axis A1, respectively. can

Accordingly, since the first angle adjusting means 210 and 310 are provided on both sides of the first rotation unit 300, the rotation angle of the ultraviolet light emitting unit 500 around the first rotation axis A1 is stably maintained. It can be. Therefore, since UV rays can be stably irradiated at various angles at low cost with a simple configuration, sterilization can be performed quickly and effectively.

At this time, from the first rotation axis (A1), the first adjustment hole (H1a) formed on one side (S1) of the first rotation unit 300 and the first side (S1') of the rotation support unit 200 and the first Formed on the first distance D1 to the protrusion P1a and the other side surface S2 of the first rotational part 300 and the second side surface S2' of the rotation support part 200 from the first rotation axis A1 The second distance D2 between the first adjusting hole H1b and the first protrusion P1b may be different from each other.

That is, a first distance D1 from the first rotating shaft A1 to the first adjusting holes H1a and H1b formed on both sides of the first rotating part 300 and the first protrusions P1a and P1b, and The second distance D2 may be different from each other.

As the distance from the first rotation shaft A1 to the first protrusion P1 increases, the supporting force acting on the first protrusion P1 inserted into the first adjustment hole H1 increases, so that the first protrusion P1 The rotation angle at which the UV light emitting unit 500 rotates around the first rotation axis A1 may be stably maintained.

On the other hand, since the smaller the distance from the first rotating shaft A1 to the first protrusion P1 is, the smaller the supporting force acting on the first protrusion P1 inserted into the first adjusting hole H1 is. It is easy to rotate the UV light emitting unit 500 around the first rotation axis A1 by removing the first protrusion P1 inserted into the hole H1 from the first adjusting hole H1.

Therefore, based on the first rotation unit 300, the first adjustment holes H1a and H1b and the first protrusions P1a and P1b are formed on one side at a distance D1 and D2 from the first rotation shaft A1, , If the first adjustment holes H1a and H1b and the first protrusions P1a and P1b are formed at a distance D2 and D1 from the first rotation axis A1 on the opposite side, the first protrusion P1 is an ultraviolet light emitting unit. 500 can stably maintain the rotational angle rotated around the first rotation axis A1, and at the same time, the first protrusion P1 inserted into the first adjustment hole H1 is inserted into the first adjustment hole H1. It is easy to rotate the ultraviolet light emitting unit 500 around the first rotational axis A1 by removing it from the outside.

That is, the first adjustment holes H1a and H1b and the first protrusions P1a and P1b are formed on both sides of the first rotational part 300 at an equally close distance from the first rotational shaft A1. One protrusion (P1) can stably maintain the rotation angle of the UV light emitting unit 500. In addition, the first adjustment holes H1a and H1b and the first protrusions P1a and P1b are formed on both sides of the first rotational unit 300 at the same distance from the first rotational shaft A1. It is easy to rotate the ultraviolet light emitting unit 500 around the first rotation axis A1 by removing the first protrusion P1 from the first adjustment hole H1.

As such, from the first rotation shaft A1, the first adjustment hole H1a formed on one side surface S1 of the first rotation unit 300 and the first side surface S1' of the rotation support unit 200 and the first control hole H1a. Formed on the first distance D1 to the protrusion P1a and the other side surface S2 of the first rotational part 300 and the second side surface S2' of the rotation support part 200 from the first rotation axis A1 Since the second distance D2 between the first adjusting hole H1b and the first protrusion P1b is different from each other, the first protrusion P1 causes the UV light emitting unit 500 to be centered around the first rotation axis A1. At the same time, it is possible to stably maintain the rotation angle rotated by, and at the same time, the ultraviolet light emitting unit 500 is moved to the first rotation shaft by taking out the first protrusion P1 inserted into the first adjustment hole H1 from the first adjustment hole H1. It is easy to rotate around (A1).

In addition, a first distance D1 from the first rotation axis A1 to the first adjustment holes H1a and H1b and the first protrusions P1a and P1b formed on both sides of the first rotation unit 300, and Since the second distance D2 is different from each other, the first protrusions P1a and P1b on both sides of the first rotating part 300 are formed using two conventional ball plungers B having balls B2 only at one end. can do. Accordingly, the first protrusions P1a and P1b on both sides of the first rotating part 300 can be easily formed at low cost with a simple configuration, and maintenance costs can be reduced.

For example, as shown in the drawing, two conventional ball plungers (B) provided with only one end of the ball (B2) are attached to one side (S1) and the other side (S2) of the first rotation unit 300 to the first rotation shaft ( The first protrusions P1a and P1b on both sides of the first rotational part 300 may be easily formed by inserting them laterally at different distances from A1) and facing in opposite directions.

An upper surface of the main member 300a ( FIGS. 8 , 9 , and 14 ) of the first rotating unit 300 may be formed with a protrusion 330 protruding upward.

The protrusion 330 may correspond to a cylindrical shape centered on the second rotation axis A2. The protruding part 330 may be inserted through the second rotating part 400 . Accordingly, the second rotation unit 400 may be rotatably coupled to the first rotation unit 300 about the second rotation axis A2. The outer diameter of the upper end of the protrusion 330 is greater than the inner diameter of the through hole of the second rotation unit 400 through which the protrusion 330 is inserted, so that the second rotation unit 400 can be constrained to the first rotation unit 300.

It may include a second protrusion (P2) formed by leaving.

However, it is not limited to this configuration. Accordingly, the second angle adjusting unit 320 of the first rotating unit 300 may include a second adjusting hole H2 to be described later instead of the second protrusion P2.

Accordingly, since the rotatable angle of the second rotation unit 400 with respect to the first rotation unit 300 is limited, the power cable or data cable connected to the UV light emitting unit 500 is twisted and damaged or the UV light emitting unit 500 separation can be prevented.

Regarding the rotation limiting unit R, it will be described later with reference to FIGS. 22 to 24.

[Second rotating part]

The second rotation unit 400 may be rotatably coupled to the first rotation unit 300 about a second rotation axis A2 penetrating the first rotation unit 300 . Here, the second rotation axis A2 may extend in a direction crossing the first rotation axis A1.

In addition, the second rotation unit 400 may be combined with the UV light emitting unit 500 .

22 to 24 , the second rotating unit 400 rotates around the second rotating shaft A2 so that the UV light emitting unit 500 can emit ultraviolet rays at various angles. For example, as shown in the drawing, the ultraviolet light emitting unit 500 may rotate in place according to the rotation of the second rotation unit 400 to irradiate ultraviolet rays in all directions.

That is, when the first rotation unit 300 rotates and the second rotation unit 400 rotates about the second rotation axis A2 in a state in which the ultraviolet light emitting unit 500 is laid down with respect to the base unit 100, the ultraviolet rays The light emitting unit 500 may face downward (FIGS. 3 and 22), may face sideways (FIGS. 4 and 23), or may face upward (FIGS. 5 and 24).

As described above, the UV light emitting unit 500 may rotate in place according to the rotation of the second rotating unit 400 . Accordingly, the ultraviolet sterilization device can irradiate ultraviolet rays at various angles, and the angle of irradiation of ultraviolet rays of the ultraviolet light emitting unit 500 can be easily adjusted.

In addition, the second rotating unit 400 may support the UV light emitting unit 500 .

25 to 27 , the second rotational unit 400 may be rotatably coupled to the first rotational unit 300 about a second rotational shaft A2 penetrating the first rotational unit 300. .

In addition, the second rotation unit 400 may be provided with a second angle adjusting unit 410 (see FIG. 27 ) for adjusting a rotation angle of the first rotation unit 300 .

For example, as shown in FIG. 27 , a second angle adjusting unit 410 may be provided on the lower surface of the second rotating unit 400 .

The second angle adjusting means 420 of the second rotating unit 400 includes, for example, one or more second adjusting holes H2 formed in a circumferential direction at a predetermined distance D3 from the second rotating shaft A2. can include For example, four second control holes H2 may be formed along the circumferential direction at intervals of approximately 90 degrees around the second rotational axis A2.

However, it is not limited to this configuration. Accordingly, the second angle adjusting unit 420 of the second rotating unit 400 may include the aforementioned second protrusion part P2 instead of the second adjusting hole H2.

The aforementioned second protrusion P2 may be inserted into the second adjustment hole H2. That is, the second protrusion P2 may be inserted into any one of one or more (four in FIG. 27) second adjustment holes H2.

When the second protrusion P2 is inserted into the second control hole H2, the second protrusion P2 cannot easily escape the second control hole H2, so the second rotation part 400 and the second rotation part 400 A specific rotational angle formed by the UV light emitting unit 500 coupled to the first rotational unit 300 around the second rotational axis A2 can be stably maintained. Here, the specific rotation angle may be determined according to the location of the second adjustment hole H2 formed along the circumferential direction around the second rotation axis A2.

On the other hand, even if the second protrusion P2 is inserted into the second adjusting hole H2, if a considerable amount of force is applied to the second rotating part 400, the second protrusion P2 may escape the second adjusting groove H2. Therefore, the second rotating part 400 can rotate. When the second rotating part 400 rotates, the second protruding part P2 can be inserted into the neighboring second adjusting groove H2 in the circumferential direction. Until the second protrusion (P2) leaves the second control groove (H2) and is reinserted into the neighboring second control groove (H2), the second protrusion (P2) is the first rotating part (300)/auxiliary member (300b). ), or may receive pressure from the lower surface of the second rotation unit 400 (in the drawing, pressure is received by the lower surface of the second rotation unit 400).

As such, the first rotation unit 300 and the second rotation unit 400 are provided with second angle adjusting means 320 and 410 for adjusting the rotation angle of the second rotation unit 400 with respect to the first rotation unit 300. Since the angle of rotation of the ultraviolet light emitting unit 500 around the second rotation axis A2 is stably maintained, ultraviolet rays can be stably irradiated at various angles with a simple configuration at low cost. Thus, sterilization can be performed quickly and effectively.

In addition, the second angle adjusting means (320, 410) is installed on the upper surface of the first rotating unit 300 or the lower surface of the second rotating unit 400 at a predetermined distance (D3) from the second rotating shaft (A2) in the circumferential direction. one or more second control holes (H2) formed; and a second protrusion P2 formed on the lower surface of the second rotating unit 400 or on the upper surface of the first rotating unit 300 at a predetermined distance D3 from the second rotating shaft A2. (P2) may be inserted into the second control hole (H2). Accordingly, it is possible to configure the second angle adjusting means 320 and 410 with a simple configuration and low cost.

A part of the ball B2 may protrude upward from the upper surface of the first rotating part 300 or protrude downward from the lower surface of the second rotating part 400, and a part of the protruding ball B2 may be part of the above-mentioned second protruding part. (P2) may be applicable.

As described above, when the second protrusion P2 is out of the second control groove H2, it may receive pressure from the upper surface of the first rotating part 300 or the lower surface of the second rotating part 400. When the second protrusion P2 receives pressure, the ball B2 may move to the inside of the housing B3, and thus the spring B1 may be elastically deformed. When the ball (B2) or the first protrusion (P1) reaches the front of the first control groove (H1), the spring (B1) can move the ball (B2) to the outside of the housing (B3) by the restoring force, and accordingly The second protrusion P2 may be inserted into the second control groove H2.

In this way, the second angle adjusting means (320, 410) includes a ball plunger (B) configured to include a spring (B1), a ball (B2) and a housing (B3), the ball plunger (B) is a first It is inserted in the vertical direction into the hole formed on the upper surface of the rotary part 300 or the lower surface of the second rotary part 400, and a part of the ball B2 protrudes upward from the upper surface of the first rotary part 300 or the second rotary part ( 400), the second angle adjusting means 320, 410 can be configured at a low cost with a simple configuration, since a portion of the ball B2 protrudes downward and corresponds to the second protruding portion P2.

In addition, since the second protrusion P2 elastically deforms the spring B1 and moves inside the housing B3 when the second protrusion P2 comes out of the second control groove H2, the second protrusion P2 ), and the frictional interference occurring between the first rotating part 300 or the second rotating part 400 is reduced so that the second protruding part P2, the first rotating part 300 and the second rotating part 400 are deformed or damaged By preventing this, durability can be improved.

As shown in FIGS. 22 and 24 according to rotation, the second rotation unit 400 may be caught by the rotation limiting unit R provided in the first rotation unit 300 .

For example, as shown in the drawing, a portion of the second rotating portion 400 may extend more outward in the radial direction from the second central axis A2 than the other portion, and a portion extending further outward in the radial direction extends in the radial direction. Outwardly protruding surfaces C1 and C2 may be formed. Accordingly, the rotation limiting unit R provided in the first rotating unit 300 may be caught on the protruding surfaces C1 and C2 of the second rotating unit 400 .

Accordingly, the ultraviolet light emitting unit 500 can irradiate ultraviolet rays at various angles with a simple configuration and at low cost. Thus, sterilization can be performed quickly and effectively.

In particular, in a state in which the ultraviolet light emitting unit 500 is tilted or laid at an angle with respect to the base unit 100 by the rotation of the first rotation unit 300, the rotation of the second rotation unit 400 only moves upwards and downwards. However, since ultraviolet rays can be irradiated from the side as well, there is no limit to the angle of irradiation of ultraviolet rays.

In addition, a plurality of the rotation support 200, the first rotation unit 300, the second rotation unit 400, and the ultraviolet light emitting unit 500 may be radially disposed on the base unit 100, and the first rotation unit 300 ) According to the rotation of the plurality of UV light emitting units 500 may be erected radially or inclined or laid down with respect to the base unit 100 .

For example, as shown in the drawing, a scale 710 may be displayed on the outer circumferential surface of the cable pipe 700b along the lifting direction.

As such, since the scale 710 is displayed on the elevation unit 700 along the elevation direction, the height of the elevation unit 700 can be accurately and easily adjusted.

The controller 900 may control the elevation of the elevation unit 700 based on the distance measured by the distance sensor 510 . For example, as shown in FIGS. 3, 5 and 28, in a state in which the UV light emitting unit 500 is rotated to face upward or downward, the control unit 900 is located above or below the distance sensor 510. A distance value with the sterilization target 50 may be transmitted. When the received distance value is greater than a preset reference value, the control unit 900 may raise or lower the elevating unit 700 to position the ultraviolet light emitting unit 500 close to the object 50 to be sterilized.

In this way, a distance sensor 510 for measuring the distance to the object to be sterilized 50 is provided in front of the ultraviolet light emitting unit 500, and the control unit 900 moves up and down based on the distance measured by the distance sensor 510.

For example, as shown in FIG. 1 or 4, in a state in which the ultraviolet light emitting unit 500 is rotated to face the horizontal (front, rear, left and right) direction, the control unit 900 controls the object to be sterilized in front of the distance sensor 510. The distance value from (50) can be delivered. If the received distance value is greater than a preset reference value, the controller 900 may control the moving unit 800 to position the ultraviolet light emitting unit 500 close to the object 50 to be sterilized.

In this way, the distance sensor 510 for measuring the distance to the object to be sterilized 50 is provided in front of the ultraviolet light emitting unit 500, and the control unit 900 moves based on the distance measured by the distance sensor 510. By controlling the unit 800, the ultraviolet light emitting unit 500 can approach the sterilization target object 50 while accurately measuring the distance between the ultraviolet light emitting unit 500 and the sterilization target object 50, so that sterilization is quick and can be done effectively.

For example, when the control unit 900 raises/lowers the elevation unit 700 by a predetermined height, the amount of change in the distance from the object to be sterilized 50 before and after the elevation/fall of the elevation unit 700 corresponds to the predetermined height. When corresponding to the height, the control unit 900 may determine that the UV light emitting unit 500 is laid down with respect to the base unit 100 and faces upward/downward. On the other hand, if the amount of change in the distance from the object to be sterilized 50 before and after the elevation/lowering of the elevation unit 700 is 0, the controller 900 determines that the ultraviolet light emitting unit 500 is erected with respect to the base unit 100. can do.

It is possible to determine whether the UV light emitting unit 500 is erected, tilted or laid down with respect to the base unit 100 based on the measured change in distance from the object 50 to be sterilized.

For example, when the control unit 900 controls the moving unit 800 to move the ultraviolet light emitting unit 500 horizontally forward by a predetermined distance, the amount of change in distance from the object to be sterilized 50 before and after horizontal forward movement If this corresponds to the predetermined distance, the control unit 900 may determine that the UV light emitting unit 500 is standing on the base unit 100 and facing forward. On the other hand, if the amount of change in the distance from the object to be sterilized 50 before and after horizontal forward movement of the ultraviolet light emitting unit 500 is 0, the controller 900 determines that the ultraviolet light emitting unit 500 is laid down with respect to the base unit 100 can judge

By including, even if the UV light emitting unit 500 rotates at various angles, the position of the sterilization target 50 can be accurately determined, and only some of the light emitting elements 520 are turned on according to the position of the sterilization target 50, so energy efficiency is improved. and the lifespan of the light emitting device 520 may be extended. In addition, by dividing the plurality of light emitting devices 520 into a plurality of groups G according to positions and lighting each group G, the circuit can be simplified and manufacturing and management can be facilitated.
