The inner protrusion 431 is formed to protrude from the through portion 413 where the installation space c and the passages a and b are connected, and extends from the inner circumferential surface of the mounting portion 430 toward the center of the mounting portion 430. By being formed to protrude, it serves to support the UV irradiation unit 420 installed on the mounting unit 430 so that it does not escape toward the module body unit 410 side.

The fixing support 440 is coupled to the mounting portion 430 to fix the UV irradiation unit 420 inside the mounting portion 430 .

In this embodiment, the fixed support 440 is illustrated as being provided in the form of a stopper covering the inner circumferential surface of the mounting portion 430 and coupled to the inner circumferential surface of the mounting portion 430 through screwing. The fixing support portion 440 serves to fix the UV irradiation portion 420 to the inside of the mounting portion 430 by pressing the substrate 421 of the ultraviolet irradiation portion 420 toward the inner protrusion 431 .

On the other hand, the ultraviolet irradiation unit 420 installed inside the mounting unit 430 as described above is installed on the substrate 421 installed on the mounting unit 430 and the substrate 421 to emit ultraviolet rays toward the passages a and b. It is provided in a form including an LED 423 for irradiation.

The LED 423 irradiates ultraviolet rays having a peak wavelength between 200 and 280 nm toward the passages a and b, and is installed at a designated location so that the ultraviolet rays can be evenly irradiated throughout the passages a and b. .

Among ultraviolet rays, ultraviolet rays having a peak wavelength located between 270 and 280 nm, in particular, ultraviolet rays having a peak wavelength at 275 nm have excellent sterilization effects.

In this embodiment, it is exemplified that the LED 423 is provided to emit ultraviolet rays having a peak wavelength at 275 nm, and the sterilization action is active in the flow paths (a, b) by the action of the LED 423 provided in this way. can happen

However, in order to enjoy an efficient level of sterilization effect, UVC region, in particular, ultraviolet rays having a peak wavelength of about 250 to 280 nm may be used.

According to this embodiment, the LED 423 is installed to be positioned on an imaginary bisector that bisects the interior angle formed by the first flow path (a) and the second flow path (b), and the first flow path (a) and the second flow path ( UV is irradiated toward b).

The first connection pipe part 411 and the second connection pipe part 415 are connected so that the first flow path (a) and the second flow path (b) are exposed within an ultraviolet irradiation angle range of the LED 423 .

For example, when the irradiation angle of the LED 423 is 120°, the first connection pipe part 411 and the second connection pipe part 415 are interior angles formed by the first flow path (a) and the second flow path (b). They are connected so as to be within this 120°, more preferably 90°.

This is so that the first flow path (a) and the second flow path (b) are exposed within the ultraviolet irradiation angle range of the LED 423, so that the area to which ultraviolet rays are irradiated on the first flow path (a) and the second flow path (b) This is to ensure that the entirety of the first flow path (a) and the second flow path (b) is evenly irradiated with ultraviolet rays.

Inside the mounting part 430, a protective cover 450 may be further provided. The protective cover 450 is installed inside the mounting portion 430, more specifically, between the penetrating portion 413 and the ultraviolet irradiation portion 420 to shield the passages a and b and the LED 423.

While being fixed, the O-ring 470 is in close contact with the inner protrusion 431 and the protective cover 450 to seal between the protective cover 450 and the module main body 410 .

As described above, the UV irradiation unit 420 installed inside the mounting unit 430 may receive power through the wire 480 .

According to this embodiment, the ultraviolet irradiator 420 is connected to a power supply device (not shown) through the connection of the board 421 and the wire 480, and the wire extending from the power supply device to the fixed support 440 ( A wire passage hole 441 for passing the wire 480 toward the substrate 421 may be formed.
