1 and 2, the present invention is constructed as follows.

The main body 100 constitutes an air conduit (1) having an oval or circular shape inside, and an air inlet (3) on one side of the air conduit (1) and an air outlet (4) on the other side of the air conduit (1). do. The air intake (3) structure and the air outlet (4) structure can be configured to have the opposite position.

An ultraviolet lamp (6) for sterilization is provided inside the air duct (1), and the periphery is composed of a reflector (2).

This reflective plate 2 is composed of a curved surface R with a curvature.

A pedestal (8) is formed in the lower portion of the air duct (1), and a fan (7) for sucking air is provided in the direction of the air intake (3).

The upper portion of the air duct (1) constitutes a blocking band (5) that blocks ultraviolet light so that ultraviolet rays are not exposed to the outside from the outside.

A power supply unit provided with an operating lamp 10 on the upper end of the blocker 5 or a part of the main body, and a circuit board for driving electrical devices such as an infrared lamp 6 and a fan 7 inside the lower part of the pedestal 8 (14) is provided.

A part of the main body 100 is provided with a power jack 9 for inputting power, and this power jack 9 is composed of a power adapter 13 for connecting a cigar jack for vehicle power or general power with a power cable 11 .

For user's safety, when disassembling the main body (1), the power is automatically cut off.

In this configuration, when the fan 7 under the air conduit 1 operates, air is sucked into the air inlet 3 , the air is sterilized inside the air conduit 1 and discharged through the air outlet 4 .

The sterilization effect is the amount of UV radiation (illuminance x time). It is determined by the product of effective irradiance and irradiation time, that is, the amount of irradiation, and the more the amount of irradiation, the greater the sterilization effect.

The size of the present invention is applied from a compact structure for easy portability to a home office, hospital interior, and restaurant.

The wavelength range of ultraviolet light is 10 nm to 400 nm. The ultraviolet lamp 6 configured in the present invention is composed of a lamp or an ultraviolet LED that emits ultraviolet rays having a wavelength of 250 nm to 260 nm. That is, the wavelength band of the ultraviolet lamp 6 has a sterilization effect of 1,000 to 10,000 times that of near ultraviolet 300 nm to 400 nm. The output of the UV lamp (6) is selected according to the use.

1 and 2, the inner surface of the air conduit 1 configured in a curved shape around the ultraviolet lamp 6 is an aluminum plate stainless plate, or a reflective surface 2 polished glass surface, or aluminum is deposited. It is composed of a reflective surface (2).

Ultraviolet light is light. When light hits an absorbing surface, it is scattered or absorbed and converted into other energy. Therefore, the higher the reflectance of the reflective surface 2, the higher the performance. In the present invention, it is recommended to configure the reflectance to be 80% or more.

The ultraviolet lamp 6 of the present invention selectively uses a mercury lamp or an ultraviolet LED lamp. Ultraviolet LED is a semiconductor light source designed to emit ultraviolet light with a wavelength of 200 nm to 280 nm.

The irradiation angle of these UV LEDs is comprised between 30° and 180°. For example, it is composed of 30°45°60°90°120°180°, but the irradiance angle of 180° or more decreases the efficiency. However, when the ultraviolet lamp 6 is provided in the center inside the air duct 1 as shown in FIGS.

The UV lamp 6 with an irradiation angle of 30 degrees or less has a strong sterilization power, but has a narrow sterilization range.

Therefore, when the irradiation angle is 30°45°60°90°120°180°, for example, the irradiation angle of 30° means that UV rays are diffused within the range of 30°, so that the 30° range is one beam. (Beam) means to become a unit. When these beams are emitted to the outside, the output of UV rays is diffused and extinguished according to the irradiation angle.

However, in the present invention, the ultraviolet rays having such an irradiation angle continuously reflect back on the reflective surface 2 inside the air conduit 1 in a beam unit, and have a pumping action that intersects and overlaps the entire interior of the air conduit 1 It is formed with a UV net. That is, the entire inside of the air conduit 1 becomes a powerful sterilization conduit because ultraviolet rays are pumped from the reflective surface 2 and overlapped to build a single ultraviolet net.

In more detail, the ultraviolet rays of the ultraviolet lamp 6 irradiated from the focal position F (F=R/2) of the curved surface R with curvature as shown in FIG.

As shown in (b) of Figure 3, the ultraviolet rays irradiated within the focus (F) are diffused.

As shown in (C) of FIG. 3 , the light incident on the reflective surface 2 is reflected at the angle of reflection (B) equal to the angle of incidence (A).

Therefore, as for the ultraviolet rays irradiated with an irradiation angle of 30 degrees or more, the ultraviolet beams in which all of the catadioptric actions of FIGS. do.

Since the entire interior of the air conduit 1 is composed of a reflective surface 2 as shown in Fig. 3(d), the ultraviolet beam of the ultraviolet lamp 6 is air having a circular curved surface even if it has various reflection light paths. It is continuously reflected and overlapped inside the conduit (1) so that it is all present inside the air conduit (1). Therefore, the entire inside of the air duct (1) is formed as a sterilization net by the ultraviolet net.

This works the same even when the reflective surface 2 has an elliptical shape as shown in FIG. 3(e).

As shown in (f) of FIG. 3, the shape of the reflective surface 2 may be configured in a polygonal shape such as a square, a hexagon, an octagon, etc. in a polygonal shape in the horizontal direction. This shape also increases the effect of half-pumping as it becomes a polygonal shape close to the curvature (R) with respect to the center of the air conduit (1).

4 is an explanatory view of the action of the sterilization net by the ultraviolet net of the present invention.

Ultraviolet radiation travels with little or no loss in air. Therefore, when the reflective surface 2 is combined with the ultraviolet lamp 6 inside the curved surface R having a curvature, when the ultraviolet lamp 6 continuously emits ultraviolet rays, the reflection continues continuously and alternately. By overlapping pumping, the sterilizing power inside the air duct (1) is geometrically increased.

As shown in Fig. 4, the UV rays of the UV lamp 6 having an irradiation angle of 90 degrees each 45 degrees left and right with respect to the center line are incident at 45 degrees left and right and are reflected at 45 degrees, so the three first. Article 2. A third reflection point 6a .6b. 6c may be set.

Ultraviolet rays irradiated in the left direction are reflected at the first reflection point 6a, and then reflected in the order of the second reflection point 6b, which is 90 degrees apart, and the third reflection point 6c again. As long as it continuously emits ultraviolet light, it continues to reflect it.

UV rays irradiated at 45 degrees to the right are in reverse order 3. Article 2. The first reflection points (6c, 6b, 6c) are reflected in the order, and this also continues to reflect as long as the ultraviolet lamp (6) continuously emits ultraviolet rays.

Therefore, within the irradiation angle of 90 degrees left and right, it continuously reflects at various reflection angles as shown in Fig. 3 (a), Fig. 3 (b), and Fig. 3 (c). Due to the pumping action that cross-reflects and overlaps innumerable reflections, the entire interior of the air conduit 1 is reflected innumerably and overlapped to form a UV net like a net.

In order to generate such a pumping effect, the curved surface (R) of the reflective surface (2) has to be formed on the inner surface having a curvature of the reflective surface (2) in Fig. 3 (a), Fig. 3 (b), and Fig. 3 It should have the same light-collecting action as in (c).

That is, light is reflected and overlapped inside the air duct ( ). When the reflective surface 2 is formed on the outer surface of the curved surface R, the ultraviolet beam is diffused, so that cross reflection or overlapping of the amount of light does not occur.

The sterilization net (網=net) structure by this ultraviolet net is shown in Figs. The same logic is applied in Fig. 7,

For example, as shown in FIG. 5 , in the ultraviolet lamp 6 having an irradiation angle of 60 degrees, the reflection points are set in a triangular shape with an interval of 60 degrees on the reflective surface 2 of the air conduit 1 . In this case, one ultraviolet lamp 6 has reflection points in three places by the same logic as in FIG. 4 .

The internal reflection effect of UV rays reflected at these reflection points is cross-reflected and overlapped as shown in FIGS. 3(a), 3(b), 3(c), and 3(d). The sterilization effect of these three reflection points has the sterilization power of 3 times 3 powers 9 times. In other words, since ultraviolet rays are emitted from three directions to reflect and refract and overlap each other, when the ultraviolet lamp 6 of 1w is used, the sterilization power is increased with the same amount of light as the irradiation amount of about 9w.

According to this logic, when three UV lamps (6) having a sterilization effect of 9 times are configured inside at intervals of 60 degrees, they are cross-overlapping and reflecting again to form a sterilization network of UV rays, so 3 x 9 times, 27 times have sterilizing power.

This calculation is a horizontal standard. Therefore, if 8 UV lamps 6 are configured in the longitudinal direction of the air conduit 1 as shown in FIG. 2, 27 times x 8 pieces = 216 times.

By the same logic, when composed of a UV lamp 6 having an irradiation angle of 90 degrees as shown in FIG. 6, the reflection overlaps in a quadrangular form in the 90 degree left and right directions on the reflective surface inside the air conduit, so that UV rays are reflected at 4 reflection points. There is an effect, and since one of these ultraviolet lamps 6 acts as in Fig. 3 (a), Fig. 3 (b), and Fig. 3 (c), the amount of reflection overlaps, so the enhancement effect of 4 to 4 is 16 times. appear.

When the ultraviolet lamps 6 having a 16-fold effect are composed of four, they have a sterilization power of 64 times with 16 times x 4 pieces.

Also, as shown in FIG. 2, when eight UV lamps 6 are configured in the longitudinal direction of the air conduit 1, a UV net having a sterilization effect of 64 times x 8 times = 512 times is constituted.

With the same logic, when the ultraviolet lamp 6 having an irradiation angle of 120 degrees is configured in a hexagonal shape at 120 degrees intervals as shown in FIG. Since the UV rays that are generated overlap each other again, it has a sterilization power of 36 times, which is the number of 6 chairs.

When the six UV lamps 6, which are enhanced by 36 times, are provided at regular intervals, they are cross-overlapping and reflected by the same action, so that 36 times x 6 pieces = 216 times the sterilization effect is obtained. Also, as shown in FIG. 2, when about 8 UV lamps 6 are provided in the longitudinal direction of the air duct 1, 216 times x 8 pieces can form a UV net having an irradiation amount of 1,728 times.

The sterilization power of these reflected and overlapping ultraviolet rays is geometrically increased by the ultraviolet ray net (UV NET) formed by the ultraviolet rays. That is, as described above, compared to the general sterilization structure without a reflective structure, the present invention is at least 3 times more, the UV lamp 6 with an irradiation angle of 60 degrees is 216 times, the UV lamp 6 with an irradiation angle of 90 degrees is 512 times, and the irradiation Each 120 degree UV lamp 6 has a UV net having a strong sterilization power of up to 1,728 times.

The present invention will be described by way of example as shown in FIGS. 1 and 2 .

These examples are not intended to limit the numerical values. It is for the purpose of describing the present invention in more detail.

The configuration of the air conduit (1) has an inner diameter (a) of 8 cm, length (b) of 10 cm, and a total product height of 12 cm. The interior is composed of a mirror-like reflective surface (2).

One size of the UV lamp 6 provided inside the air conduit 1 is 6mmX6mm in width and length, respectively, and as shown in Figs. Eight UV LEDs are provided at appropriate intervals in the longitudinal direction of the air duct (1).

The internal reflection surface 2 of the air duct 1 is formed as an internal curved surface having a curvature of 40 mm.

The diameter of the fan 7 for introducing and discharging air to the lower portion of the air conduit 1 is 8 cm close to the diameter a of the air conduit 1 as shown in FIG. 2 .

The rotation speed of the fan 7 is 2,500 rpm (Revolution per minute) and the noise is 30 dB to make it rotate quietly. The air-flow of the fan 7 having this rotation speed is generally 43 CFM (Cubic Feet Per) minute).

Since this embodiment is the same as in FIG. 5 described above, when the ultraviolet lamp 6 is configured in one line in the air conduit 1, it is 16 times in the length direction, and when it is configured in 4 lines, it is 64 times in the longitudinal direction. When composed of 8, it has a strong sterilization power of 512. That is, since the length of the internal reflection surface 2 of the air duct 1 is 8 cm in diameter and 10 cm in length, it is possible to construct a strong ultraviolet network of 8 cm in diameter and 10 cm in length. That is, in this embodiment, the air passes through a 10 cm long UV NET having 512 times the sterilization power at a speed of 43 CFM, so that it sterilizes instantaneously and quickly.

The overall size is 8cm x 10cm x 12cm, which is a good size to carry, and since it is easy to move, store and install, it can be installed inside a vehicle or on a table and used as portable.

In addition, the present invention can obtain a sterilization effect quickly. For example, when the present invention is installed in a vehicle, assuming that the size of the interior space of the vehicle is 6feet X 4feet X 6feet, the total space becomes 144cfm. When the air in this 144 cfm space is circulated by the fan 7 having a flow rate of 43 cfm, it is possible to sterilize all the air inside the vehicle in 3 minutes and 34 seconds.

If three elements are installed in the element, it is possible to sterilize all the air inside the car in about one minute. As for the performance of the fan 7, if the diameter of the rotational speed (RPM) of the fan 7 is increased, the sterilization rate is increased.

The action of the fan 7 allows the air to pass through the ultraviolet sterilization net in the air conduit 1 quickly, but the sterilization power of the ultraviolet net is multiplied by 3 to 512 times, so that instant sterilization is possible.

In this structure of the present invention, when plural are combined in parallel, the sterilization time becomes that much faster.

In the configuration of the present invention, as shown in FIGS. 1 and 2, the internal shape of the block 5 is configured in a curved shape to accumulate a certain amount of air discharged to the air outlet 4, and then sequentially . By discharging, the sterilization time can be extended by delaying the exhaust passage time of the air.

In addition, this blocker (5) can prevent harm to the human body from ultraviolet rays by preventing the ultraviolet rays from being exposed to the outside. This can ensure the safety of users.

In addition, such a power supply unit can be configured as a cigar jack so that the vehicle power can be used as needed.

The present invention can be installed inside a car, such as a taxi, as shown in FIG. 8, can be installed in a study room, a telecommuting room, etc., in a personal indoor space as shown in FIG. 9, and can be used by attaching it to the ceiling or wall of a business place.

As shown in Fig. 10, it can be used in combination on the individual desk 23 or on the desk 23 itself.

It can also be combined inside an air purifier or air conditioner.
