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 specifically, to an ultraviolet sterilization device and an ultraviolet sterilization method that can sterilize quickly and effectively at low cost with a simple configuration.

Ultraviolet rays are widely used for low-cost, simple, and rapid sterilization. For example, commercially available ultraviolet sterilization devices are equipped with ultraviolet lamps that sterilize by irradiating ultraviolet rays.

Ultraviolet sterilization devices can be effectively used in spaces where frequent sterilization is required, such as livestock barns, hospital rooms, operating rooms, and passageways.

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

The prior art regarding an ultraviolet sterilization device that can change the height and angle of irradiating ultraviolet rays is as follows.

Korean Patent No. 10-1742447 relates to an ultraviolet sterilization robot, which includes a lamp unit that generates ultraviolet light, a reflection unit that induces a change in direction so that the ultraviolet light emitted from the lamp unit is emitted in one direction, and a beam perpendicular to the body. It includes a support part disposed in the longitudinal direction and capable of moving up and down and rotating in a first rotation direction, and a connection part connecting the lamp part and the support part and rotatable in a second rotation direction, wherein the support part moves up and down or rotates in the first rotation direction. By doing so, the entire ultraviolet sterilizing device can be moved up and down or rotated in the first rotation direction to concentrate the ultraviolet light emitted from the lamp unit in the multi-contact area, thereby providing a high-intensity sterilizing effect.

However, in the prior art, the entire ultraviolet sterilizing device rotates in the first rotation direction, so the lamp unit cannot irradiate ultraviolet rays toward the side while the lamp unit is tilted in the second rotation direction. Accordingly, the prior art has limitations in the direction of ultraviolet ray irradiation.

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

You can.

The cover 150 may support the rotation support unit 200. Specifically, one side of the cover 150 may be coupled to the rotation support unit 200 and the other side may be coupled to the neighboring rotation support unit 200 as shown in the drawing, or, unlike the drawing, may be coupled to the base unit 100. there is. Accordingly, 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. As a result, the rotation support unit 200 can be prevented from being deformed or the rotation support unit 200 from being separated from the base unit 100.

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

Referring to FIGS. 8 and 9, each ultraviolet light emitting unit 500 is connected to 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. Can be rotatably coupled to. Let's look at each configuration.

[Bass part]

The base unit 100 may have a plate shape and may be installed on the upper part of the above-described lifting unit 700. For example, the base portion 100 may be installed on the upper part of the lifting column 700a.

A penetration groove (T) penetrating upward and downward may be formed on one side of the base portion 100.

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

Additionally, the base portion 100 may define a base surface. The base surface may refer to a virtual plane of the surface of the base portion 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 can rotate about the first rotation axis A1 on the base unit 100. Here, the first rotation axis A1 may be formed to penetrate the rotation support unit 200 and may extend in a direction substantially parallel to the base surface defined by the base unit 100.

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

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

Referring further to FIGS. 10 to 13, the first angle adjustment means (210a, 210b) of the rotation support unit 200 are, for example, positioned in the circumferential direction at a predetermined distance (D1, D2) from the first rotation axis (A1). It may include one or more first adjustment holes (H1a, H1b) formed along.

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

Meanwhile, a first adjustment hole is installed on the first side (S1') and the second side (S2') of the rotation support unit 200 at a first distance (D1) and a second distance (D2) from the first rotation axis (A1). (H1a, H1b) or first protrusions (P1a, P1b) may be formed, respectively.

For example, as shown in the drawing, first adjustment holes H1a and H1b may be formed on the first side S1' and the second side S2' of the rotation supporter 200, respectively. In addition, unlike the drawing, first protrusions P1a and P1b may be formed on the first side S1' and the second side S2' of the rotation supporter 200, respectively, and the first side S1' And the first protrusion P1 may be formed on one of the second side surfaces S2', and the first adjustment hole H1 may be formed on the other one.

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.

[First round]

The first rotation unit 300 may be rotatably coupled to the rotation support unit 200 about a first rotation axis A1 that passes through 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 portion 100.

Additionally, the first rotating part 300 may be combined with the second rotating part 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 rotating part 300 rotates about the first rotating axis A1, the ultraviolet light emitting part 500 may be erected with respect to the base part 100 (FIGS. 10 and 11) or tilted at an angle. It can be laid down (Figures 12 and 13) or laid down (Figure 22). When a plurality of first rotating parts 300, ultraviolet light emitting parts 500, etc. are radially arranged on the base part 100, a plurality of ultraviolet light emitting parts 500 are generated according to the rotation of the first rotating part 300. It can be erected radially (FIGS. 1, 6, and 7), tilted at an angle (FIG. 2), or laid down (FIG. 3) with respect to the base portion 100.

Additionally, the first rotating part 300 may support the second rotating part 400 so that the second rotating part 400 can rotate about the second rotating axis A2. Here, the second rotation axis A2 may be formed to penetrate the first rotation part 300 and may extend in a direction intersecting the first rotation axis A1.

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

Let's look at the first rotating part 300 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 axis A1 that passes through the rotation support unit 200.

Additionally, the first rotating unit 300 may be provided with a first angle adjusting means 310 for adjusting the rotation angle with respect to the rotating 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 rotating part (300), first angle adjustment means (310a, 310b, Fig. 16) ) may be provided.

For example, the first angle adjusting means 310a and 310b of the first rotating part 300 are first protrusions formed at a predetermined distance (D1, D2, FIGS. 19 and 20) from the first rotating axis (A1). It may include (P1a, P1b).

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

The first protrusion (P1) may be inserted into the first adjustment 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 adjustment holes H1.

When the first protrusion (P1) is inserted into the first control hole (H1), the first protrusion (P1) cannot easily escape from the first control hole (H1), so the first rotating part (300) and the ultraviolet light emitting part (500) The specific rotation angle formed with the rotation support 200 by rotating about the first rotation axis A1 can be stably maintained. Here, a 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).

Meanwhile, even if the first protrusion (P1) is inserted into the first adjustment hole (H1), if a significant force is applied to the first rotating part (300), the first protrusion (P1) moves out of the first adjustment groove (H1). Therefore, the first rotating part 300 can rotate. When the first rotating part 300 rotates, the first protrusion P1 may be reinserted into the first adjustment groove H1 adjacent in the circumferential direction. Until the first protrusion (P1) leaves the first control groove (H1) and is reinserted into the neighboring first control groove (H1), the first protrusion (P1) is on the side (S1, S2) or may be pressured by the sides (S1', S2') of the rotation supporter 200 (in the drawing, pressure is received by the sides of the rotation supporter).

In this way, the rotation support unit 200 and the first rotation unit 300 are provided with first angle adjustment means 210 and 310 for adjusting the rotation angle of the first rotation unit 300 with respect to the rotation support unit 200, so that ultraviolet rays Since the rotation angle of the light emitting unit 500 around the first rotation axis A1 is maintained stably, ultraviolet rays can be stably irradiated at various angles with a simple configuration and at low cost. Accordingly, sterilization can be performed quickly and effectively.

In addition, the first angle adjustment means (210, 310) is located on the side of the rotation support unit 200 or the first rotation unit 300 along the circumferential direction at a predetermined distance (D1, D2) from the first rotation axis (A1). One or more first adjustment holes (H1) formed; And a first protrusion (P1) formed on the side of the first rotation unit 300 or the rotation support unit 200 at a predetermined distance (D1, D2) from the first rotation axis (A1), and the first protrusion ( P1) may be inserted into the first adjustment hole (H1). Accordingly, the first angle adjustment means (210, 310) can be constructed with a simple configuration at low cost.

Referring further to Figure 21, the first angle adjustment 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) that includes a housing (B3) that accommodates the spring (B1).

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

As described above, when the first protrusion (P1) deviates from the first adjustment groove (H1), the side surfaces (S1, S2) of the first rotating part (300) or the side surfaces (S1', S2') of the rotation support part (200) can be pressured by When the first protrusion P1 receives pressure, the ball B2 may move inside the housing B3 and the spring B1 may be elastically deformed accordingly. When the ball (B2) or the first protrusion (P1) reaches the front of the first adjustment 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 adjustment means (210, 310) includes a ball plunger (B) composed of a spring (B1), a ball (B2), and a housing (B3), and the ball plunger (B) is the first angle adjusting means (210, 310). It is laterally inserted into the hole formed in the rotating part 300 or the rotating support part 200, and a portion of the ball B2 protrudes laterally on the side of the first rotating part 300 or the rotating support part 200. A ball ( Since a portion of B2) corresponds to the first protrusion (P1), the first angle adjustment means (210, 310) can be constructed with a simple structure and at low cost.

In addition, when the first protrusion (P1) comes out of the first adjustment groove (H1), the first protrusion (P1) moves inside the housing (B3) while elastically deforming the spring (B1), so that the first protrusion (P1) ) and the first rotating part 300 or the rotating support part 200 are reduced to prevent the first protrusion (P1), the first rotating part 300, and the rotating support part 200 from being deformed or damaged. This can improve durability.

Meanwhile, on one side (S1) and the other side (S2) of the first rotating part 300, there is a first adjustment hole (H1a) at a first distance (D1) and a second distance (D2) from the first rotation axis (A1). H1b) or first protrusions (P1a, P1b) may be formed, respectively.

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

In addition, as described above, the first side (S1') and the second side (S2') of the rotation support unit 200 have a first distance (D1) and a second distance (D2) from the first rotation axis (A1). First adjustment holes (H1a, H1b) or first protrusions (P1a, P1b) may be formed, respectively.

When the first protrusion (P1) is formed on one of the sides (S1, S2) of the first rotating part (300), the side of the rotation support unit (200) facing the side (S1, S2) on which the first protruding part (P1) is formed. A first adjustment hole (H1) may be formed in (S1', S2'), and if the first adjustment hole (H1) is formed on either side (S1, S2) of the first rotating part 300, the first adjustment hole (H1) may be formed in (S1', S2'). A first protrusion P1 may be formed on the side surfaces S1' and S2' of the rotation supporter 200 facing the side surfaces S1 and S2 where the adjustment hole H1 is formed.

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

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

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

That is, the 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 The second distance D2 may be different from each other.

As the distance from the first rotation axis (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 the first protrusion (P1) The ultraviolet light emitting unit 500 can stably maintain a rotation angle around the first rotation axis A1.

On the other hand, the smaller the distance from the first rotation axis (A1) to the first protrusion (P1), the smaller the support force acting on the first protrusion (P1) inserted into the first adjustment hole (H1), so the first adjustment hole (H1) It is easy to rotate the ultraviolet light emitting unit 500 about the first rotation axis A1 by removing the first protrusion P1 inserted into the hole H1 from the first adjustment hole H1.

Therefore, based on the first rotating part 300, first adjustment holes (H1a, H1b) and first protrusions (P1a, P1b) are formed on one side at a short distance (D1, D2) from the first rotating axis (A1), On the other side, if first control holes (H1a, H1b) and first protrusions (P1a, P1b) are formed at a long distance (D2, D1) from the first rotation axis (A1), the first protrusions (P1) are ultraviolet light emitting parts. (500) can stably maintain the rotation 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 connected to the first adjustment hole (H1). It is easy to pull it out and rotate the ultraviolet light emitting unit 500 about the first rotation axis A1.

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

In this way, from the first rotation axis (A1), the first adjustment hole (H1a) and the first Formed at a first distance D1 to the protrusion P1a, from the first rotation axis A1, on the other side S2 of the first rotation unit 300 and on the second side S2' of the rotation support unit 200. Since the second distance D2 from the first control hole H1b to the first protrusion P1b is different from each other, the ultraviolet light emitting unit 500 of the first protrusion P1 is centered on the first rotation axis A1. It is possible to stably maintain the rotation angle, and at the same time, the first protrusion (P1) inserted into the first adjustment hole (H1) is pulled out from the first adjustment hole (H1) and the ultraviolet light emitting unit 500 is rotated along the first rotation axis. 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 a ball B2 only at one end. can do. Accordingly, the first protrusions P1a and P1b on both sides of the first rotating unit 300 can be easily formed with a simple configuration at low cost and maintenance costs can be reduced.

For example, as shown in the drawing, two conventional ball plungers (B) having a ball (B2) only at one end are placed on one side (S1) and the other side (S2) of the first rotating part (300) with a first rotating axis ( The first protrusions P1a and P1b on both sides of the first rotating part 300 can be easily formed by inserting them laterally at different distances from A1) and facing opposite directions.

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

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

The auxiliary member 300b (FIGS. 8, 9, and 14) may be coupled to the upper surface of the main member 300a (FIGS. 8, 9, and 14) of the first rotating unit 300. The upper surface of the auxiliary member 300b may face the lower surface of the second rotating part 400.

The first rotating part 300 may be provided with a second angle adjusting means 320 that adjusts the rotation angle of the second rotating part 400 with respect to the first rotating part 300.

For example, the second angle adjustment means 320 may be provided on the upper surface of the auxiliary member 300b of the first rotating part 300.

For example, the second angle adjusting means 320 of the first rotating part 300 is positioned at a predetermined distance D3 from the second rotating axis A2 on the upper surface of the first rotating part 300 (i.e., the upper surface of the auxiliary member). It may include a second protrusion (P2) formed with.

However, it is not limited to this configuration. Accordingly, the second angle adjustment means 320 of the first rotating part 300 may include a second adjustment hole (H2), which will be described later, instead of the second protrusion (P2).

The second protrusion (P2) may correspond to a portion of the ball (B2) of the ball plunger (B) and may be inserted into the second adjustment hole (H2). In this regard, it will be described later.

The first rotating part 300 may be provided with a rotation limiting part (R) that protrudes in the direction of the second rotating axis (A2) and is caught by the second rotating part 400.

For example, the rotation limiter (R) may be installed at a point spaced apart from the second rotation axis (A2) by a predetermined distance, and protrudes upward from the upper surface of the first rotation portion (300) or the auxiliary member (300b). It can be.

However, it is not limited to this configuration. Accordingly, the rotation limiter (R) may be provided in the second rotating part 400 rather than the first rotating part 300, and may protrude in the direction of the second rotating axis A2 and be caught in the first rotating part 300. there is.

In this way, the rotation limiter (R) protrudes from the first rotating part 300 or the second rotating part 400 in the direction of the second rotating axis A2 and is caught by the second rotating part 400 or the first rotating part 300. It can be provided. Accordingly, the angle at which the second rotating part 400 can rotate with respect to the first rotating part 300 is limited, so the power cable or data cable connected to the ultraviolet light emitting part 500 may be twisted and damaged or the ultraviolet light emitting part 500 It can prevent separation from.

Regarding the rotation limiter (R), it will be described later with reference to FIGS. 22 to 24.

[Part 2]

The second rotating part 400 may be rotatably coupled to the first rotating part 300 about a second rotating axis A2 that passes through the first rotating part 300. Here, the second rotation axis A2 may extend in a direction intersecting the first rotation axis A1.

Additionally, the second rotating part 400 may be combined with the ultraviolet light emitting part 500.

Referring further to FIGS. 22 to 24, the second rotation unit 400 rotates around the second rotation axis A2 so that the ultraviolet light emitting unit 500 can irradiate ultraviolet rays at various angles. For example, as shown in the drawing, the ultraviolet light emitting unit 500 can rotate in place according to the rotation of the second rotating unit 400 and radiate ultraviolet rays in all directions.

That is, when the first rotating part 300 rotates and the ultraviolet light emitting part 500 is laid down with respect to the base part 100, and the second rotating part 400 rotates around the second rotating axis A2, the ultraviolet rays The light emitting unit 500 may face downward (FIGS. 3, 22), laterally (FIG. 4, 23), or upward (FIG. 5, 24).

As described above, the ultraviolet 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 ultraviolet irradiation angle of the ultraviolet ray emitting unit 500 can be easily adjusted.

Additionally, the second rotating part 400 may support the ultraviolet ray emitting part 500.

Referring further to FIGS. 25 to 27, the second rotating part 400 may be rotatably coupled to the first rotating part 300 about a second rotating axis A2 penetrating the first rotating part 300. .

Additionally, the second rotating unit 400 may be provided with a second angle adjusting means 410 (FIG. 27) for adjusting the rotation angle with respect to the first rotating unit 300.

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

For example, the second angle adjusting means 420 of the second rotating part 400 includes one or more second adjusting holes (H2) formed in the circumferential direction at a predetermined distance (D3) from the second rotating axis (A2). may include. For example, four second adjustment holes H2 may be formed along the circumferential direction at approximately 90-degree intervals around the second rotation axis A2.

However, it is not limited to this configuration. Accordingly, the second angle adjustment means 420 of the second rotating part 400 may include the above-described second protrusion P2 instead of the second adjustment hole H2.

The above-described second protrusion P2 may be inserted into the second adjustment hole H2. That is, the second protrusion P2 can 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 from the second control hole (H2), so the second rotating part (400) and the second rotating part (400) A specific rotation angle formed by the ultraviolet light emitting unit 500 coupled to the first rotating unit 300 around the second rotating axis A2 can be stably maintained. Here, a specific rotation angle may be determined according to the position of the second adjustment hole (H2) formed along the circumferential direction around the second rotation axis (A2).

Meanwhile, even if the second protrusion (P2) is inserted into the second adjustment hole (H2), if a significant force is applied to the second rotating part 400, the second protrusion (P2) will deviate from the second adjustment groove (H2). Therefore, the second rotating part 400 can rotate. When the second rotary part 400 rotates, the second protrusion P2 may be reinserted into the second adjustment groove H2 adjacent to 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 connected to the first rotating part (300)/auxiliary member (300b). ) can be pressured by the upper surface or the lower surface of the second rotating part 400 (in the drawing, it is pressured by the lower surface of the second rotating part 400).

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

In addition, the second angle adjustment means (320, 410) is located on the upper surface of the first rotating part (300) or the lower surface of the second rotating part (400) in the circumferential direction at a predetermined distance (D3) from the second rotating axis (A2). One or more second control holes (H2) formed; and a second protrusion (P2) formed on the lower surface of the second rotating part 400 or the upper surface of the first rotating part 300 at a predetermined distance D3 from the second rotating axis A2, and the second protruding part (P2) can be inserted into the second control hole (H2). Accordingly, the second angle adjustment means (320, 410) can be constructed with a simple configuration at low cost.

The second angle adjustment means (320, 410) may include the ball plunger (B) of FIG. 21 like the first angle adjustment means (210, 310).

The ball plunger (B) may be inserted in a vertical direction into a hole formed on the upper surface of the first rotating part 300 or the lower surface of the second rotating part 400. A portion of the ball B2 may protrude upward on the upper surface of the first rotating portion 300 or may protrude downward on the lower surface of the second rotating portion 400, and a portion of the protruding ball B2 may be the aforementioned second protrusion. It may correspond to (P2).

As described above, when the second protrusion P2 deviates from the second adjustment groove H2, it may be pressured by 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 inside the housing B3 and the spring B1 may be elastically deformed accordingly. When the ball (B2) or the first protrusion (P1) reaches the front of the first adjustment 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 adjustment groove (H2).

In this way, the second angle adjustment means (320, 410) includes a ball plunger (B) composed of a spring (B1), a ball (B2), and a housing (B3), and the ball plunger (B) is the first angle adjustment means (320, 410). It is inserted in the vertical direction into a hole formed on the upper surface of the rotating part 300 or the lower surface of the second rotating part 400, and a portion of the ball B2 protrudes upward on the upper surface of the first rotating part 300 or the second rotating part ( By protruding downward from the lower surface of 400) and a portion of the protruding ball B2 corresponding to the second protrusion P2, the second angle adjustment means 320, 410 can be constructed with a simple structure and at low cost.

In addition, when the second protrusion (P2) comes out of the second adjustment groove (H2), the second protrusion (P2) elastically deforms the spring (B1) and moves inside the housing (B3), so that the second protrusion (P2) moves inside the housing (B3). ) and the first rotating part 300 or the second rotating part 400, the frictional interference is reduced, so that the second protruding part (P2), the first rotating part 300, and the second rotating part 400 are deformed or damaged. Durability can be improved by preventing damage.

As the second rotating part 400 rotates, it may be caught by the rotation limiter (R) provided in the first rotating part 300, as shown in FIGS. 22 and 24.

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

[UV light emitting part]

The ultraviolet light emitting unit 500 may be coupled to the upper surface of the second rotating unit 400.

As described above, the ultraviolet light emitting unit 500 may be erected with respect to the base unit 100 according to the rotation of the first rotating unit 300 (FIGS. 10 and 11), or may be tilted at an angle (FIGS. 12 and 11). Figure 13) Can also be laid down (Figure 22).

When a plurality of ultraviolet light emitting units 500 are radially disposed on the base unit 100, the plurality of ultraviolet light emitting units 500 are radially arranged with respect to the base unit 100 as the first rotating unit 300 rotates. It can be erected (Figures 1, 6 and 7), tilted (Figure 2) or laid down (Figure 3).

Also, as described above, the ultraviolet light emitting unit 500 may rotate in place according to the rotation of the second rotating unit 400. That is, when the first rotating part 300 rotates and the ultraviolet light emitting part 500 is laid down with respect to the base part 100, and the second rotating part 400 rotates around the second rotating axis A2, the ultraviolet rays The light emitting unit 500 may face downward (FIGS. 3, 22), laterally (FIG. 4, 23), or upward (FIG. 5, 24).

The ultraviolet light emitting unit 500 may be configured to include a plurality of light emitting elements 520, and the ultraviolet light emitting unit 500 may be provided with a distance sensor 510. In this regard, it will be described later.

In this way, the ultraviolet sterilization device includes a base portion 100 that defines the base surface; A rotation support portion 200 coupled to the base portion 100; A first rotary part 300 rotatably coupled to the rotation support part 200 about a first rotation axis A1 penetrating the rotation support part 200; A second rotating part 400 rotatably coupled to the first rotating part 300 about a second rotating axis A2 penetrating the first rotating part 300; and an ultraviolet light emitting unit 500 coupled to the second rotating unit 400, wherein the first rotation axis A1 extends in a direction substantially parallel to the base surface, and the second rotation axis A2 extends in a direction substantially parallel to the base surface. ) can be extended in a direction that intersects. Accordingly, the ultraviolet light emitting unit 500 can irradiate ultraviolet rays at various angles with a simple configuration and at low cost. Accordingly, sterilization can be performed quickly and effectively.

In particular, in a state in which the ultraviolet light emitting unit 500 is tilted or laid down with respect to the base unit 100 due to the rotation of the first rotating part 300, it moves not only upward and downward due to the rotation of the second rotating part 400. 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 unit 200, the first rotating unit 300, the second rotating unit 400, and the ultraviolet light emitting unit 500 may be radially arranged on the base unit 100, and the first rotating unit 300 ) Depending on the rotation, the plurality of ultraviolet light emitting units 500 may be radially erected, tilted, or laid down with respect to the base unit 100. Accordingly, since the ultraviolet sterilization device can simultaneously irradiate ultraviolet rays to multiple areas at various angles, sterilization can be performed quickly and effectively.

Figures 28 and 29 are perspective views showing a state in which the ultraviolet light emitting part is located at different heights in the ultraviolet sterilizing device of Figs. 1 to 5.

Referring to FIGS. 28 and 29 , the ultraviolet light emitting unit 500 is positioned at different heights as the lifting unit 700 is raised and lowered.

The height at which the ultraviolet light emitting unit 500 is located can be easily confirmed through the scale 710 displayed on the lifting unit 700 along the lifting direction. For example, as shown in the drawing, a scale 710 may be displayed along the ascending and descending direction on the outer peripheral surface of the cable pipe 700b.

In this way, by displaying the scale 710 along the lifting direction on the lifting unit 700, the height of the lifting unit 700 can be adjusted accurately and easily.

Figures 30 and 31 are front and side views showing an ultraviolet light emitting unit according to an embodiment of the present invention.

Referring to FIGS. 30 and 31, a distance sensor 510 may be provided on the front of the ultraviolet light emitting unit 500 to measure the distance to the sterilization object 50 (FIGS. 32 and 33).

Accordingly, even if the ultraviolet light emitting unit 500 rotates at various angles, the distance between the ultraviolet light emitting unit 500 and the sterilizing object 50 or the position of the sterilizing object 50 is accurately measured using the minimum number of distance sensors 510. can do.

The control unit 900 may control the raising and lowering of the lifting unit 700 based on the distance measured by the distance sensor 510. For example, as shown in FIGS. 3, 5, and 28, when the ultraviolet light emitting unit 500 is rotated to face upward or downward, the control unit 900 is located upward or downward from the distance sensor 510. The distance value from the sterilizing object 50 can be received. If the received distance value is greater than a preset reference value, the control unit 900 may raise or lower the lifting unit 700 to position the ultraviolet light emitting unit 500 closer to the sterilizing object 50.

In this way, a distance sensor 510 is provided in front of the ultraviolet light emitting unit 500 to measure the distance to the sterilization object 50, and the control unit 900 moves up and down based on the distance measured by the distance sensor 510. By controlling the raising and lowering of the unit 700, the ultraviolet light-emitting unit 500 can approach the object 50 to be sterilized while accurately measuring the distance between the ultraviolet light-emitting part 500 and the object 50 to be sterilized, thereby enabling sterilization. It can be done quickly and effectively.

Additionally, the control unit 900 can control the moving unit 800 to move the body unit 600 and the ultraviolet light emitting unit 500 based on the distance measured by the distance sensor 510. For example, as shown in Figure 1 or Figure 4, in a state where the ultraviolet light emitting unit 500 is rotated to face the horizontal (forward, backward, left and right) direction, the control unit 900 controls the sterilization object located in front of the distance sensor 510. The distance value from (50) can be received. If the received distance value is greater than a preset reference value, the control unit 900 can control the moving unit 800 to position the ultraviolet light emitting unit 500 closer to the sterilizing object 50.

In this way, a distance sensor 510 is provided in front of the ultraviolet light emitting unit 500 to measure the distance to the sterilization object 50, 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 object 50 to be sterilized while accurately measuring the distance between the ultraviolet light emitting part 500 and the object 50 to be sterilized, so sterilization is rapid and It can be performed effectively.

Meanwhile, the control unit 900 controls the lifting unit 700 to move the ultraviolet light emitting unit 500 up and down, and the sterilization object 50 measured by the distance sensor 510 according to the vertical movement of the ultraviolet light emitting unit 500. ) It is possible to determine whether the ultraviolet light emitting unit 500 is erected, tilted at an angle, or laid down with respect to the base unit 100 based on the change in distance from the base unit 100.

For example, when the control unit 900 raises/lowers the lifting unit 700 by a predetermined height, the amount of change in the distance to the sterilizing object 50 before and after raising/lowering the lifting unit 700 is determined by the predetermined height. Corresponding to the height, the control unit 900 may determine that the ultraviolet light emitting unit 500 is lying down with respect to the base unit 100 and is facing upward/downward. On the other hand, if the amount of change in the distance to the sterilization object 50 before and after the raising/lowering of the lifting unit 700 is 0, the control unit 900 determines that the ultraviolet light emitting unit 500 is erected with respect to the base unit 100. can do.

In this way, the control unit 900 controls the lifting unit 700 to move the ultraviolet light emitting unit 500 up and down, and the sterilization target measured by the distance sensor 510 according to the vertical movement of the ultraviolet light emitting unit 500 ( By determining whether the ultraviolet light emitting unit 500 is erected, tilted, or laid down with respect to the base unit 100 based on the change in distance from the base unit 100, the ultraviolet light emitting unit 500 with respect to the base unit 100 It is possible to easily determine the inclination of or the direction in which the ultraviolet light emitting unit 500 is facing.

In addition, the control unit 900 controls the moving unit 800 to move the ultraviolet light emitting unit 500 in the horizontal direction (forward, backward, left and right), and the distance sensor 510 moves the ultraviolet light emitting unit 500 in the horizontal direction. Based on the measured change in distance from the sterilization object 50, it can be determined whether the ultraviolet light emitting unit 500 is erected, inclined at an angle, or laid down with respect to the base unit 100.

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 the distance to the sterilization object 50 before and after the horizontal forward movement Corresponding to this predetermined distance, the control unit 900 may determine that the ultraviolet light emitting unit 500 is erected with respect to the base unit 100 and is facing forward. On the other hand, if the amount of change in the distance to the sterilization object 50 before and after the horizontal forward movement of the ultraviolet light emitting unit 500 is 0, the control unit 900 determines that the ultraviolet light emitting unit 500 is lying down with respect to the base unit 100. You can judge.

In addition, in FIGS. 30 and 31, the ultraviolet light emitting unit 500 may be configured to include a plurality of light emitting elements 520, each belonging to one group (G) among the plurality of groups (G) depending on the position. .

For example, the light-emitting device 520 located at the top of the ultraviolet light-emitting portion 500 belongs to the first group (G1), and the light-emitting device 520 located at the center of the ultraviolet light-emitting portion 500 belongs to the second group (G1). The light emitting device 520 belonging to the group G2 and located below the ultraviolet light emitting unit 500 may belong to the third group G3.

The control unit 900 can turn on only the light emitting elements 520 belonging to the group (G) corresponding to the position of the sterilizing object 50 among the plurality of light emitting elements 520 based on the distance measured by the distance sensor 510. there is.

In this regard, look at FIGS. 32 and 33.

Figures 32 and 33 are diagrams showing a state in which the ultraviolet light emitting unit of Figures 30 and 31 irradiates ultraviolet rays to an object to be sterilized.

Referring to FIGS. 32 and 33, when the sterilization object 50 is located in the upper and central portions of the front of the ultraviolet light emitting unit 500, the control unit 900 controls the first group (G1) and the first group (G1) of the ultraviolet light emitting unit 500. Only the light emitting element 520 belonging to group 2 (G2) can light up.

On the other hand, when the sterilization object 50 is located in the lower part of the front of the ultraviolet light emitting unit 500, the control unit 900 turns on only the light emitting elements 520 belonging to the third group (G3) of the ultraviolet light emitting unit 500. You can.

At this time, the control unit 900 may determine where the sterilizing object 50 is located on the front of the ultraviolet light emitting unit 500 based on the distance measured by the distance sensor 510.

Here, the sterilization object 50 may mean an object such as a ceiling, a wall, a table, or an operating table, and an object far away from the ultraviolet light emitting unit 500 is an object from which the ultraviolet light emitting unit 500 is far away. It may be excluded from the sterilization target 50 until it approaches. This is because the sterilization effect is low even when ultraviolet rays are radiated to an object far away from the ultraviolet ray emitting unit 500.

In this way, the ultraviolet sterilization device is rotatably coupled to the rotation support part 200 coupled to the base part 100, and emits a plurality of lights, each belonging to one group (G) among the plurality of groups (G) depending on the position. An ultraviolet light emitting unit 500 that includes an element 520 and is equipped with a distance sensor 510 on the front that measures the distance to the sterilizing object 50; And a control unit 900 that turns on only the light emitting elements 520 belonging to the group (G) corresponding to the position of the sterilizing object 50 among the plurality of light emitting elements 520 based on the distance measured by the distance sensor 510. By including it, even if the ultraviolet light emitting unit 500 rotates at various angles, the position of the object to be sterilized 50 can be accurately determined, and only some of the light emitting elements 520 are turned on depending on the position of the object to be sterilized 50, thereby improving energy efficiency. This can be improved and the lifespan of the light emitting device 520 can be extended. Additionally, by dividing the plurality of light emitting devices 520 into a plurality of groups (G) by position and lighting them for each group (G), the circuit can be simplified and manufacturing and management can be facilitated.

In addition, the ultraviolet sterilization device controls the moving part 800 to move the ultraviolet light emitting part 500 in the horizontal direction (forward, backward, left and right), and the distance sensor 510 measures the UV light emitting part 500 according to the horizontal movement of the ultraviolet light emitting part 500. Based on the change in distance from the sterilized object 50, it can be determined whether the ultraviolet light emitting unit 500 is erected, tilted, or laid down with respect to the base unit 100.

The decision result determined in the status determination step (S1300) may be delivered to the user or the control unit 900.

However, the status determination step (S1300) is not an essential component and can be omitted.

In the position adjustment step (S1400), the ultraviolet sterilization device can move the ultraviolet light emitting unit 500 up and down by controlling the lifting unit 700 based on the measured distance.

Additionally, the ultraviolet sterilization device can control the moving unit 800 based on the measured distance to move the ultraviolet light emitting unit 500 in the horizontal direction.
