Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Referring to fig. 1, the sterilization apparatus 100 according to the first embodiment includes a first housing 111, a second housing 112, and a light source module 120.

The first and second cases 111 and 112 are fixed to the light source module 120 and disposed on the outside flow path pipe 190.

The inner walls of the first and second cases 111 and 112 are formed in a structure corresponding to a part of the outer wall of the flow path tube 190. For example, if the flow path tube 190 is of a circular cross-sectional structure, the inner walls of the first and second cases 111 and 112 may be formed as curved surfaces.

The light source module 120 is fixed to the outer walls of the first and second cases 111 and 112. The first and second housings 111 and 112 include housing fastening portions 119 for fastening to the light source module 120. For example, the case fastening portion 119 may be a groove fastened with a screw.

The light source module 120 includes a substrate 121 and a sterilizing light source 122. The substrate 121 is formed with wiring for supplying power to the sterilizing light source 122. For example, the substrate 121 may be a printed circuit substrate (Printed Circuit Board). However, the kind of the substrate 121 is not limited to a printed circuit substrate, and may be any kind as long as it includes a wiring for supplying power to the sterilizing light source 122.

The sterilizing light source 122 emits sterilizing light. For example, germicidal light source 122 may be a light emitting diode or a package including a light emitting diode. Sterilizing light is a collective term for ultraviolet rays having a sterilizing function. For example, the germicidal light may include at least one wavelength band of UVC (100 nm to 280 nm), UVB (280 nm to 315 nm), and UVA (315 nm to 400 nm). If the sterilizing light source 122 receives power supply from the substrate 121, sterilizing light is emitted.

The sterilizing light source 122 is disposed at one side of the substrate 121. At this time, the sterilizing light source 122 is disposed on the substrate 121 so as to emit sterilizing light to the flow path tube 190.

One side of the light source module 120 may be fixed to an outer wall of the first case 111, and the other side may be fixed to an outer wall of the case 112.

The light source module 120 includes a module fastening part 123 for fastening with the first and second cases 111 and 112. For example, the module fastening part 123 may be a groove fastened with a screw.

After the light source modules 120 are disposed on the first and second cases 111 and 112, fastening members 130 such as screws may be fastened to the module fastening parts 123 and 119. In this way, the first case 111, the second case 112, and the light source module 120 are coupled to each other.

In the present embodiment, the case where the first case 111, the second case 112, and the light source module 120 are fastened to each other by the fastening member 130 in a screw fastening manner is described as an example. However, the fastening manner for fixing the first housing 111, the second housing 112, and the light source module 120 to each other is not limited thereto. For example, the light source module 120 may be fixed to the first and second cases 111 and 112 by inserting the module fastening part 123 into the case fastening part 119 or inserting the case fastening part 119 into the module fastening part 123. Alternatively, the light source module 120 may be fixed to the first and second cases 111 and 112 by fastening the module fastening part 123 and the case fastening part 119 in a hinge manner. As such, the manner of fixing the light source module 120 to the first and second cases 111 and 112 is not limited to the screw fastening manner, and may be any manner that facilitates assembly and disassembly.

Thus, the first case 111, the second case 112, and the light source module 120 assembled with each other are disposed on the flow path tube 190, and the sterilizing light emitted from the light source module 120 is irradiated to the flow path tube 190.

The inner walls of the first and second cases 111 and 112 may be formed to include a reflective substance. For example, the inner walls of the first and second cases 111 and 112 may be coated with a reflective substance. Alternatively, the first housing 111 and the second housing 112 may themselves be formed of a reflective material.

The thickness of the first case 111 and the second case 112 or the distance between the first case 111 and the second case 112 may be decided in consideration of the distance between the light source module 120 and the flow path tube 190 and the pointing angle of the light source module 120. That is, the thickness and the distance between the first case 111 and the second case 112 may be determined such that the sterilizing light of the light source module 120 is maximally irradiated to the flow path pipe 190.

Conventionally, a sterilization device is formed such that a housing to which a light source module is attached surrounds a flow path tube. At this time, the case is formed as an integral body which cannot be separated, and a plurality of light source modules may be fixed so as not to be easily detached from the case. Therefore, if a part of the housing or one of the plurality of light source modules fails, the entire sterilization device needs to be replaced.

According to an embodiment of the present invention, the sterilizing device 100 may assemble or disassemble the first housing 111, the second housing 112, and the light source module 120 in a simple manner. Therefore, when one of the first casing 111 and the second casing 112 fails, the sterilizing apparatus 100 can be disassembled to replace only the failed casing. Alternatively, since the sterilizing device 100 is easily disassembled, if a malfunction occurs in the light source module 120, the light source module 120 may be separated from the first and second cases 111 and 112 and replaced. As such, since the sterilizing apparatus 100 according to the embodiment of the present invention can replace only the malfunctioning part, costs and waste of materials are reduced.

Hereinafter, in describing other embodiments of the sterilization apparatus, description will be given mainly of points different from those of the sterilization apparatus according to the first embodiment. Therefore, in the description about the sterilization apparatus of the other embodiments, the repeated description of the same constituent parts as those of the sterilization apparatus of the first embodiment may be omitted. Also, the omitted description may refer to the description of the sterilization apparatus according to the first embodiment.

Referring to fig. 2, the sterilizing apparatus 200 according to the second embodiment includes a first housing 111, a second housing 112, a partition 210, and a light source module 120.

The partition 210 is disposed between the upper surfaces of the first and second cases 111 and 112 and the substrate 121 of the light source module 120. One end of one fastening part 130 is fastened to the first case 111 through the light source module 120 and the partition 210. And, one end of the other fastening member 130 is fastened to the second housing 112 through the light source module 120 and the spacer 210.

The distance between the light source module 120 of the sterilizing device 200 and the flow path tube 190 becomes longer than that of the first embodiment by the partition 210. In this manner, the sterilizing device 200 may adjust the distance between the light source module 120 and the flow path tube 190 using the partition 210.

The range, the amount of light, etc. of the sterilizing light irradiated to the flow path tube 190 may be changed according to the pointing angle of the sterilizing light emitted from the light source module 120 and the distance of the light source module 120 from the flow path tube 190. The sterilizing apparatus 200 of the present invention can adjust the distance between the light source module 120 and the flow path tube 190 by the spacer 210 in consideration of the directional angle of the sterilizing light, so that the sterilizing light is sufficiently irradiated to the flow path tube 190. The spacer 210 may be manufactured in various thicknesses to adjust the distance of the light source module 120 from the flow path tube 190.

Referring to fig. 3, the sterilizing apparatus 300 according to the third embodiment includes a first housing 111, a second housing 112, a fixing member 310, and a light source module 120.

A fixing member 310 is formed on the outer walls of the first and second cases 111 and 112. The fixing member 310 is used to fix the sterilizing device 300 to the flow path tube 190.

The fixing member 310 may be formed of metal or plastic having an elastic force. One end of the fixing member 310 is connected to the outer walls of the first and second cases 111 and 112. The other end of the fixing member 310 is in contact with the outer wall of the flow channel tube 190. At this time, the distance between the other end of the fixing member 310 formed at the first housing 111 and the other end of the fixing member 310 formed at the second housing 112 may be smaller than the diameter of the flow path tube 190. Accordingly, the fixing members 310 of the first and second cases 111 and 112 may fix the sterilizing device 300 to the flow path tube 190 by pressurizing the flow path tube 190 by means of an elastic force.

In the present embodiment, a case where the fixing member 310 fixes the sterilizing device 300 to the flow path tube 190 by elastic force is described. However, the method of attaching the sterilizing device 300 to the flow path pipe 190 using the fixing member 310 is not limited thereto, and the sterilizing device 300 may be attached to the flow path pipe 190 by various methods. For example, the other end of the fixing member 310 is formed with an adhesive substance, whereby the sterilizing device 300 can be fixed to the flow channel tube 190 by an adhesive force.

In this way, the sterilizing device 300 including the fixing member 310 can be easily fixed to the flow path tube 190. Therefore, the sterilizing device 300 can be easily installed in the flow channel pipe 190, not limited to the position where the flow channel pipe 190 is installed, the shape of the flow channel pipe 190, and the like.

Also, the length of the fixing member 310 is adjustable. For example, the fixing member 310 may be formed such that one end connected to the first housing 111 is inserted into the inside of the first housing 111. At this time, the length of the fixing member 310 may be adjusted by adjusting the insertion length of one end of the fixing member 310 into the first housing 111. The fixing member 310 formed at the second housing 112 may be formed identically.

Also, the fixing member 310 may be formed to be capable of adjusting its own length (e.g., partially folded, partially inserted into another portion, etc.).

The sterilizing device 300 can adjust the distance between the light source module 120 and the flow path tube 190 by adjusting the length of the fixing member 310 as such. Further, the sterilizing device 300 may adjust the distance between the light source module 120 and the flow path tube 190 by changing the position where the fixing member 310 is fixed to the flow path tube 190.

Also, the sidewalls of the first and second cases 111 and 112 may be formed to have an inclination. At this time, the sidewalls of the first and second cases 111 and 112 having the inclination form a path through which the sterilizing light of the light source module 120 passes. The inclination of the sidewalls of the first and second cases 111 and 112 may be changed according to the pointing angle of the sterilizing light emitted from the light source module 120.

If the sidewalls of the first and second cases 111 and 112 are formed to have an inclination, loss generated by the sterilizing light emitted from the light source module 120 colliding to the sidewalls can be minimized. Accordingly, the sterilizing device 300 may improve sterilizing efficiency by minimizing loss of sterilizing light.

Fig. 4 is an exemplary view of a sterilizing apparatus according to a fourth embodiment of the present invention.

Referring to fig. 4, the sterilizing apparatus 400 according to the fourth embodiment includes a first housing 411, a second housing 412, a first light source module 430, and a second light source module 440.

The first housing 411 and the second housing 412 are constituted by an outer wall, an inner wall, and a side wall. Here, the side walls of the first housing 411 are portions connected as upper and lower surfaces of the inner wall and the outer wall of the first housing 411, respectively. The first housing 411 and the second housing 412 are arranged with respective sidewalls opposite to each other.

The first substrate 431 of the first light source module 430 is fixed on the first and second housings 411 and 412. At this time, the first sterilizing light source 432 of the first light source module 430 is located between the sidewalls of the first housing 411 and the second housing 412.

The second substrate 441 of the second light source module 440 is fixed to the lower surfaces of the first and second cases 411 and 412. At this time, the first sterilizing light source 432 of the first light source module 430 may be located between the sidewalls of the first housing 411 and the second housing 412.

The flow path pipe 190 is disposed in an inner space formed by fixing the first and second light source modules 430 and 440 in the first and second housings 411 and 412. That is, the inner walls of the first housing 411 and the second housing 412 will surround the outer wall of the flow path tube 190. The first light source module 430 and the second light source module 440 fixed to the first housing 411 and the second housing 412 emit sterilizing light to the flow channel tube 190.

The flow channel pipe 190 is made of a material that transmits sterilizing light. Accordingly, the sterilizing light emitted from the first and second light source modules 430 and 440 is irradiated to the fluid flowing inside the flow path tube 190, and the fluid is sterilized by the sterilizing light.

In the present embodiment, the first light source module 430 is disposed at an upper portion of the flow path tube 190, and the second light source module 440 is disposed at a lower portion of the flow path tube 190. That is, the sterilizing light is simultaneously irradiated to the flow channel tube 190 from the upper direction and the lower direction of the flow channel tube 190. Therefore, the sterilizing light can be uniformly irradiated to the inside of the flow channel tube 190.

If the inner walls of the first housing 411 and the second housing 412 reflect sterilizing light, the light efficiency of the sterilizing device 400 increases, and thus the sterilizing efficiency may also increase.

The flow channel pipe 190 may be an external component or a component included in the sterilizing apparatus 400 of the present invention. The sterilizing apparatus 400 according to the present embodiment is formed to assemble the first housing 411, the second housing 412, the first light source module 430, and the second light source module 440 around the flow path tube 190. Therefore, when the flow channel pipe 190 fails, the assembled components can be disassembled to easily replace the flow channel pipe 190.

A support member 420 may be formed at sidewalls of the first and second cases 411 and 412. The support member 420 may be formed to protrude from sidewalls of the first and second cases 411 and 412. The support member 420 is located between the first light source module 430 and the second light source module 440 and the flow channel tube 190. The support member 420 thus formed can prevent the first and second sterilizing light sources 432 and 442 from being damaged by collision with the flow channel tube 190.

Since the sterilizing device 400 of the present embodiment is formed to surround the flow path tube 190, an additional constituent part for fixing to the flow path tube 190 may be omitted.

Referring to fig. 5, the sterilizing apparatus 500 according to the fifth embodiment includes first to fourth housings 511 to 514 and first to fourth light source modules 520 to 550. The flow path tube 190 disposed inside the sterilizing apparatus 500 may be a constituent part of the sterilizing apparatus 500. Alternatively, the sterilizing device 500 may be attached to the flow channel pipe 190 as an external component.

The first to fourth housings 511 to 514 have inner walls formed in a structure corresponding to a part of the outer wall of the flow path tube 190. For example, the flow channel tube 190 has a circular cross-section, and the inner walls of the first to fourth cases 511 to 514 are formed into curved surfaces. However, if the flow path tube 190 is of other structure, the inner walls of the first to fourth housings 511 to 514 may be changed to a structure corresponding to the outer wall of the flow path tube 190. Alternatively, as long as the flow path tube 190 can be arranged in the inner space formed by the first to fourth housings 511 to 514, the inner walls of the first to fourth housings 511 to 154 may not be structures corresponding to the outer walls of the flow path tube 190.

Referring to fig. 5, the cross section of the first to fourth cases 511 to 514 is observed, and is configured by an outer surface constituted by two right-angle surfaces, an inner surface of a curved surface, and two side surfaces connecting the outer surface and the inner surface.

The first case 511 and the second case 512 are arranged in such a manner that one side wall of the first case 511 and one side wall of the second case 512 are opposite to each other. Also, the second housing 512 and the fourth housing 514 are arranged in such a manner that one side wall of the third housing 513 and one side wall of the fourth housing 514 face each other. And, the other side wall of the first case 511 and the other side wall of the fourth case 514 are arranged to be opposite to each other, and the other side wall of the second case 512 and the other side wall of the third case 513 are arranged to be opposite to each other.

The first light source module 520 includes a first substrate 521 and a first sterilizing light source 522. Also, the second light source module 530 includes a second substrate 531 and a second sterilizing light source 532. Also, the third light source module 540 includes a third substrate 541 and a third sterilizing light source 542. Also, the fourth light source module 550 includes a fourth substrate 551 and a fourth sterilizing light source 552.

The first light source module 520 is fixed between the first case 511 and the second case 512. One side of the first light source module 520 is fixed to an outer wall of the first case 511, and the other side is fixed to an outer wall of the second case 512.

The second light source module 530 is fixed between the second housing 512 and the third housing 513. One side of the second light source module 530 is fixed to an outer wall of the second housing 512, and the other side is fixed to an outer wall of the third housing 513.

The third light source module 540 is fixed between the third case 513 and the fourth case 514. One side of the third light source module 540 is fixed to an outer wall of the third housing 513, and the other side is fixed to an outer wall of the fourth housing 514.

The fourth light source module 550 is fixed between the first case 511 and the fourth case 514. One side of the fourth light source module 550 is fixed to the outer wall of the first housing 511, and the other side is fixed to the outer wall of the fourth housing 514.

The sterilization device 500 emits sterilization light simultaneously in the up-down, left-right direction of the flow channel pipe 190. Therefore, even when the inner diameter of the flow channel pipe 190 is large, the sterilization device 500 can sufficiently sterilize the fluid flowing through the flow channel pipe 190.

Referring to fig. 6, the sterilizing apparatus 600 according to the sixth embodiment includes first to fourth housings 511 to 514, first to fourth light source modules 520 to 550, a sealing member 620, and a transparent window 610. For convenience of explanation, the first to fourth light source modules 520 to 550 are expressed as light source modules 520 to 550. Also, the first to fourth substrates 521 to 551 are also expressed as substrates 521 to 551.

The transparent window 610 is disposed between the support member 420 and the light source modules 520 to 550. Also, the sealing member 620 is also disposed between the supporting member 420 and the light source modules 520 to 550 while being formed around the outer periphery of the transparent window 610. The sealing member 620 is made of a material having an elastic force such as silicon. Such a sealing member 620 closes the inner space formed by the first to fourth housings 511 to 514. And, the space between the light source modules 520 to 550 and the transparent window 610 is closed by the sealing member 620.

One end of the sealing member 620 contacts one surface of the supporting member 420, and the other end contacts the substrates 521 to 551 of the light source modules 520 to 550. When the light source modules 520 to 550 are fixed to the first to fourth cases 511 to 514, the substrates 521 to 551 may press the sealing member 620 toward the supporting member 420. The sealing member 620 is pressurized by the substrates 521 to 551, whereby the inner spaces of the first to fourth cases 511 to 514 can be firmly closed.

Since the sterilizing apparatus 600 according to the present embodiment has a structure in which an inner space is closed by the sealing member 620 and the transparent window 610, the inner space itself may become a flow path pipe through which fluid passes. That is, the sterilizing apparatus 600 according to the present embodiment may omit the flow path tube.

Further, since the sterilization apparatus 600 according to the present embodiment has a fluid passing through the inner space, it is formed of a material that is not corroded by the fluid. Alternatively, the inner walls of the first to fourth housings 511 to 514 of the sterilizing apparatus 600 may be coated with a material that is not corroded by the fluid.

The sealing member 620 may be fixed to the inner space formed by the first to fourth cases 511 to 514 by elastic force even without the support member 420. In this case, the supporting member 420 may be omitted.

Also, although not shown, the sterilizing apparatus 600 according to an embodiment of the present invention may further include a pressurizing member (not shown). The pressurizing member is disposed on the light source module, and can pressurize the light source module toward the housing. The light source module is further attached to the housing by means of the pressurizing member, whereby the waterproof function of the sterilizing device 600 can be improved.

Referring to fig. 7, the sterilizing device 700 according to the seventh embodiment includes first to fourth housings 511 to 514, first to fourth light source modules 520 to 550, a first sealing member 711, a second sealing member 712, and a transparent window 610.

The first sealing member 711 is disposed between the supporting member 420 and the transparent window 610. And, the second sealing member 712 is disposed between the transparent window 610 and the substrates 521 to 551 of the light source modules 520 to 550. That is, the outer periphery of the transparent window 610 is interposed between the first sealing member 711 and the second sealing member 712. The first sealing member 711 and the second sealing member 712 are formed of an elastic material such as silicon.

Accordingly, the substrates 521 to 551 will press the second sealing member 712 when the light source modules 520 to 550 are fixed to the first to fourth housings 511 to 514. At this time, not only the second sealing member 712 but also the transparent window 610 and the first sealing member 711 are pressurized, and thus the space between the substrates 521 to 551 and the supporting member 420 is sealed, so that the inner space of the sterilizing device 700 is closed.

As such, in case of using the first sealing member 711 and the second sealing member 712 separated from each other, the transparent window 610 of various sizes may be applied to the sterilizing device 700. According to the present embodiment, any size may be applied to the sterilizing device 700 as long as the transparent window 610 has a diameter greater than the distance between the support members 420 opposite to each other and less than the distance between the sidewalls of the housing opposite to each other.

The sterilizing device 800 according to the eighth embodiment includes first to fourth housings 511 to 514, first to fourth light source modules 520 to 550, a sealing member 620, and a transparent window 610. A flow channel pipe 190 is disposed in the inner space of the sterilization apparatus 800. The sterilization device 800 may include a flow path tube 190 disposed inside. Alternatively, the sterilizing device 800 may be mounted on the flow channel pipe 190 as an external constituent.

The inner space of the sterilization apparatus 800 is closed by the sealing member 620 and the transparent window 610. Therefore, the light source modules 520 to 550 can be prevented from being damaged when the flow path tube 190 is broken. For example, the sealing member 620 and the transparent window 610 block the leaked fluid from entering the light source modules 520 to 550 by the time the flow path tube 190 breaks up to cause the fluid to leak. Therefore, according to the present embodiment, even if the flow path pipe 190 is broken, the sterilizing device 800 can protect the light source modules 520 to 550 from the fluid leaked to the outside of the flow path pipe 190.

Referring to fig. 9 and 10, the sterilizing apparatus 900 according to the ninth embodiment includes a first housing 911, a second housing 912, and a light source module 920. Although the first housing 911, the second housing 912, and the light source module 920 are described as examples in the present embodiment, the present invention is also applicable to fastening between the first to fourth housings and the first to fourth light source modules of other embodiments.

The first housing 911 and the second housing 912 have a housing fastening portion 119 having a groove structure.

The light source module 920 includes a base plate 921 and a sterilizing light source 922, and a module fastening portion 930 having a groove structure is formed in the base plate 921. At this time, the module fastening portion 930 is formed in plurality on the base plate 921. For example, as shown in fig. 9 and 10, the module fastening part 930 may include a first module fastening part 931, a second module fastening part 932, and a third module fastening part 933.

The user can fasten any one of the first to third module fastening parts 931 to 933 to the case fastening part 119 using the fastening member 130.

Referring to fig. 9, the case fastening parts 119 of the first case 911 and the second case 912 are fastened to the first module fastening part 931. Also, referring to fig. 10, the case fastening parts 119 of the first case 911 and the second case 912 are fastened to the third module fastening parts 933.

According to the present embodiment, the distance L between the first housing 911 and the second housing 912 is changed according to which of the first to third module fastening parts 931 to 933 the housing fastening part 119 is fastened to.

Comparing fig. 9 and 10, it can be seen that the distance L between the first housing 911 and the second housing 912 of fig. 10 is greater than the distance L between the first housing 911 and the second housing 912 of fig. 9. That is, the distance between the inner wall of the first housing 911 and the inner wall of the second housing 912 or the size of the inner space is changed according to the position where the light source module 920 is fastened to the first housing 911 and the second housing 912. Accordingly, even if the size of the flow path pipe 190 provided with the sterilizing device 900 is changed, the flow path pipe 190 can be provided in the inner space of the sterilizing device 900 by changing the position where the light source module 920 is fastened to the first housing 911 and the second housing 912. That is, the flow path pipe 190 disposed inside the sterilizing device 900 is not limited in size. Therefore, the sterilizing device 900 matched thereto is not manufactured when the size of the flow path tube 190 disposed inside is changed. Alternatively, when the inside of the sterilizing apparatus 900 is used as a flow path pipe, the size of the internal space of the sterilizing apparatus 900 may be changed according to the flow rate.

Also, if the distance between the first housing 911 and the second housing 912 of the sterilization apparatus 900 increases, the space between the first housing 911 and the second housing 912 becomes wider. At this time, a greater number of sterilizing light sources 922 may be disposed between the first housing 911 and the second housing 912. Even if the flow channel pipe 190 is enlarged or the internal space of the sterilizing device 900 is enlarged due to an increase in the flow rate, a sufficient amount of sterilizing light can be irradiated to the fluid. Accordingly, since the sterilizing device 900 can increase the arrangement of the sterilizing light sources 922, even if the flow rate increases, the sterilizing power can be prevented from being lowered.

The present embodiment has been described taking, as an example, a case where the light source module includes a plurality of fastening holes, and the position of fastening with the housing can be changed. However, the present invention is not limited to the fastening portion of the light source module including a plurality of fastening holes. The fastening portion of the light source module may be length-adjustable. For example, the fastening portion of the light source module may be foldable and expandable.

Referring to fig. 11, the sterilizing apparatus 1000 according to the tenth embodiment includes first to fourth housings 1011 to 1014 and first to fourth light source modules 1020 to 1050.

The first light source module 1020 includes a first substrate 1021 and a first sterilizing light source 1022. Also, the second light source module 1030 includes a second substrate 1031 and a second sterilizing light source 1032. Also, the third light source module 1040 includes a third substrate 1041 and a third sterilizing light source 1042. The fourth light source module 1050 includes a fourth substrate 1051 and a fourth sterilizing light source 1052.

An insertion groove 1019 into which the light source module is inserted is formed in a side wall of the first to fourth housings 1011 to 1014. That is, the first to fourth light source modules 1020 to 1050 are not fixed to the outer wall of the fourth housing 1014 of the first housing 1011, but are fixed so as to be inserted into the first to fourth housings 1011 to 1014.

One end and the other end of the first to fourth light source modules 1020 to 1050 are inserted into insertion grooves 1019 formed at opposite sides of the first to fourth housings 1011 to 1014, respectively.

One end and the other end of the first light source module 1020 are inserted into the insertion grooves 1019 of the first housing 1011 and the second housing 1012, respectively. And, one end and the other end of the second light source module 1030 are inserted into the insertion grooves 1019 of the second and third cases 1012 and 1013, respectively. And, one end and the other end of the third light source module 1040 are inserted into the insertion grooves 1019 of the third and fourth housings 1013 and 1014, respectively. And, one end and the other end of the fourth light source module 1050 are inserted into the insertion grooves 1019 of the first housing 1011 and the fourth housing 1014, respectively.

At this time, the first to fourth substrates 1021 to 1051 may be flexible substrates. Or a part of the first substrate 1021 to the fourth substrate 1051 may be formed of a flexible material. If the whole or a part is formed of a flexible material, the first to fourth substrates 1021 to 1051 can be more easily inserted into the insertion groove 1019 of the fourth housing 1014.

In the case of the present embodiment, additional constituent parts for fixing the first to fourth light source modules 1020 to 1050 to the first to fourth housings 1011 to 1014 are not required. Therefore, since the sterilizing apparatus 1000 of the present embodiment has a simple structure, it is easy to manufacture, and it is possible to save costs and time.

Referring to fig. 12, a sterilizing apparatus 1100 according to an eleventh embodiment includes first to fourth housings 1101 to 1014 and first to fourth light source modules 1020 to 1050.

A plurality of insertion grooves into which the light source modules are inserted are formed at the sidewalls of the first to fourth housings 1101 to 1014. For example, first through fourth housings 1011, 1014 are each formed with first, second, and third insertion grooves 1111, 1112, 1113. The first to fourth light source modules 1020 to 1050 may be inserted into one of the first to third insertion grooves 1111 to 1113. If the first to fourth light source modules 1020 to 1050 are inserted into the first insertion groove 1111, they become closer to each other when they are inserted into the second insertion groove 1112 than the distance of the flow path tube 190. And, if the first to fourth light source modules 1020 to 1050 are inserted into the third insertion groove 1113, they become farther when inserted into the second insertion groove 1112 than the distance of the flow path tube 190.

As such, the sterilizing apparatus 1100 of the present embodiment can adjust the distance between the light source module and the flow path tube according to the position of the insertion groove into which the light source module is inserted. Although the description has been made in this embodiment taking the configuration of the insertion grooves from the first insertion groove 1111 to the third insertion groove 1113 as an example, the number of insertion grooves may be changed according to the selection of those skilled in the art.

Referring to fig. 13, the sterilizing apparatus 1200 according to the twelfth embodiment may include first to fourth housings 511 to 514 and first to fourth light source modules 1210 to 1240.

According to the present embodiment, the sterilizing device 1200 is inserted inside the flow path tube 190 in which the fluid flows.

The first light source module 1210 includes a substrate 1211 and a sterilizing light source 1212. At this time, the sterilizing light sources 1212 may be disposed at both sides of the substrate 1211, respectively. Like the first light source module 1210, the sterilizing light sources may be disposed on both sides of the substrate in the second, third and fourth light source modules 1220, 1230 and 1240, respectively.

Although not shown, since the first to fourth light source modules 1210 to 1240 are in direct contact with the fluid, they may be sealed by means of a waterproof member.

Accordingly, the sterilizing device 1200 can emit sterilizing light to the inside and outside of the first to fourth housings 511 to 514 at the same time.

According to the present embodiment, since the sterilizing device 1200 is inserted into the flow channel tube 190, it is possible to directly irradiate the sterilizing light to the fluid flowing through the flow channel tube 190. Therefore, the sterilization efficiency of the fluid can be improved. Further, since the sterilizing device 1200 emits sterilizing light to the inside and the outside at the same time, it is possible to sterilize both the fluid flowing outside the sterilizing device 1200 and the fluid flowing inside the sterilizing device. Also, the fluid may move heat generated from the sterilizing device 1200 to other places. That is, since heat generated from the sterilizing apparatus 1200 is radiated as the fluid moves, the sterilizing apparatus 1200 may omit a dedicated radiating member.

The sterilizing apparatus 1200 according to the present embodiment can be applied to a large-sized flow path pipe such as a drain pipe where the sterilizing apparatus cannot be disposed on the outer wall.

Although the various embodiments of the present invention have been described above, the present invention is not limited to the various embodiments and features described above, and various modifications and changes may be made without departing from the technical spirit of the scope of the claims of the present invention.
