그러나, 상기와 같은 방법들에 의하면 기상 중에 존재하는 부유미생물을 실시간 측정할 수 없으며, 별도의 샘플링 과정과 전처리 등을 포함한 일련의 수작업이 요구되므로, 이러한 방법들을 이용하여서는 공기 중 부유미생물 자동 측정 시스템을 개발할 수가 없다는 한계가 있었다.However, the above methods cannot measure the airborne microorganisms present in the gas phase in real time, and a series of manual operations including separate sampling and pretreatment are required.

The filter driver 250 includes a motor capable of forward or reverse rotation. For example, the motor may include a step motor. A rotating shaft 255 (see FIG. 4) extends from the filter driver 250 to the filter case 210.
상기 필터 구동부(250)가 구동되면 상기 회전축(255)이 회전되며, 상기 필터 케이스(210)는 상기 회전축(255)에 의하여 시계방향 또는 반시계 방향으로 회전될 수 있다. 그리고, 상기 필터부(220)는 상기 필터 케이스(210)와 함께 회전될 수 있다.When the filter driver 250 is driven, the rotating shaft 255 is rotated, and the filter case 210 may be rotated clockwise or counterclockwise by the rotating shaft 255. In addition, the filter unit 220 may be rotated together with the filter case 210.
상기 필터 케이스(210) 및 필터부(220)가 일 위치에 있을 때, 일 필터공(215)이 상기 미생물 입자유로(127)에 연통된다. 따라서, 상기 미생물 입자유로(127)를 유동한 미생물 입자는 상기 일 필터공(215)을 통하여 상기 필터부(220)에 포집된다. 이 때, 상기 미생물 입자가 포집되는 필터부(220)의 일 영역은 상기 일 필터공(215)에 의하여 상기 미생물 입자유로(127)에 노출된 영역에 대응될 수 있다.When the filter case 210 and the filter unit 220 are in one position, one filter hole 215 communicates with the microbial particle flow path 127. Therefore, the microbial particles flowing through the microbial particle flow path 127 are collected in the filter unit 220 through the one filter hole 215. In this case, one region of the filter unit 220 in which the microbial particles are collected may correspond to the region exposed to the microbial particle passage 127 by the one filter hole 215.

The light receiving unit 320 or the sterilizer 330 of the device may be located on one side.
상기 포집장치(200)의 일측에는, 미생물 입자의 유동을 위하여 구동되는 "구동장치"로서의 펌프장치(360) 및 상기 제 2 하우징(130)으로부터 상기 펌프장치(360)로 연장되는 펌프 연결부(350)가 제공된다. 상기 펌프장치(360)에는, 에어 펌프가 포함될 수 있다. On one side of the collecting device 200, the pump device 360 as a "drive device" that is driven for the flow of microbial particles and the pump connection portion 350 extending from the second housing 130 to the pump device 360 ) Is provided. The pump device 360 may include an air pump.
상기 미생물 입자유로(127)의 입자들 중, 상기 필터부(220)에 포집된 미생물 입자를 제외한 나머지 입자, 일례로 공기 입자들은 상기 펌프 연결부(350)를 경유하여 상기 펌프장치(360)로 유동할 수 있다.Among the particles of the microbial particle flow path 127, the remaining particles except for the microbial particles collected in the filter unit 220, for example, air particles, flow through the pump connection unit 350 to the pump device 360. can do.
상기 제 2 하우징(130)의 내부에는, 상기 펌프 연결부(350)와 연통되는 흡입부(310)가 포함된다. 상기 흡입부(310)는, 상기 제 2 하우징(130)의 내부에 형성되며, 상기 펌프장치(360)의 흡입력이 작용할 수 있다. 일례로, 상기 흡입부(310)는 상기 제 2 하우징(130)의 적어도 일부분이 절개 또는 관통되어 형성될 수 있다. 그리고, 상기 흡입부(310)는 상기 필터 케이스(210)의 일측, 도면상 상측에 형성될 수 있다.Inside the second housing 130, a suction part 310 communicating with the pump connection part 350 is included. The suction part 310 is formed in the second housing 130, and the suction force of the pump device 360 may act. For example, the suction part 310 may be formed by cutting or penetrating at least a portion of the second housing 130. In addition, the suction part 310 may be formed on one side of the filter case 210 and the upper side of the drawing.
따라서, 상기 펌프장치(360)가 구동되면, 상기 미생물 입자유로(127)에서의 공기유동이 발생되며, 상기 공기유동은 상기 흡입부(310)를 거쳐 상기 필터부(220)를 통과하게 된다. 이 과정에서, 미생물 입자는 상기 필터부(220)에 포집될 수 있다. 상기 미생물 입자가 분리된 이후의 공기유동은 상기 펌프 연결부(350)를 거쳐 상기 펌프장치(360)로 유동할 수 있다.Accordingly, when the pump device 360 is driven, air flow in the microbial particle flow path 127 is generated, and the air flow passes through the filter part 220 through the suction part 310. In this process, the microbial particles may be collected in the filter unit 220. The air flow after the microbial particles are separated may flow to the pump device 360 via the pump connection unit 350.
상기 펌프 연결부(350)에는, 상기 제 2 하우징(130)으로부터 상기 펌프장치(360)를 향하여 유동 단면적이 감소되는 싸이클론부(351)가 포함된다. 공기 유동은 상기 싸이클론부(351)를 지나면서 유동속도가 증가되어, 상기 펌프장치(360)로 유입될 수 있다.The pump connection portion 350 includes a cyclone portion 351 having a reduced flow cross-sectional area from the second housing 130 toward the pump device 360. The air flow may increase the flow rate while passing through the cyclone portion 351 and may be introduced into the pump device 360.
상기 펌프장치(360)는 압력손실이 발생하더라도 소정의 흡입유량을 확보하는 데 팬(fan) 보다 유리한 장치로서 이해될 수 있다. 따라서, 상기 펌프장치(360)를 사용하여 상기 미생물 입자유로(127)에서의 입자 유동을 발생함으로써, 상기 노즐부(120) 또는 필터부(220)에서 압력손실이 발생하더라도 흡입 효율이 개선될 수 있다.The pump device 360 may be understood as a device that is more advantageous than a fan to secure a predetermined suction flow rate even if a pressure loss occurs. Therefore, by generating the particle flow in the microbial particle flow path 127 using the pump device 360, even if a pressure loss occurs in the nozzle unit 120 or the filter unit 220, the suction efficiency can be improved. have.
그리고, 상기 미생물 입자유로(127)의 유동량은 비교적 소량이므로 상기 에어 펌프에는 저유량 펌프가 적용될 수 있다. 따라서, 부유 미생물 측정장치가 커지거나 무거워지는 현상을 방지할 수 있다.In addition, since the flow rate of the microbial particle flow path 127 is relatively small, a low flow rate pump may be applied to the air pump.

Figure 4 is a schematic diagram showing the internal configuration of the airborne microbial measurement apparatus according to an embodiment of the present invention, Figure 5 is a view schematically showing the configuration of the nozzle unit according to an embodiment of the present invention. 4 and 5, the operation of the airborne microbial measurement apparatus according to an embodiment of the present invention will be briefly described.
상기 펌프장치(360) 및 송풍팬(150)이 구동하면, 상기 부유 미생물 측정장치(10)의 외부에 존재하는 공기(도 5의 A)가 상기 상면부(112)의 다수의 슬릿(121)을 통하여 상기 제 1 하우징(110)의 내부로 유입된다.When the pump device 360 and the blower fan 150 are driven, air (A in FIG. 5) existing outside the airborne microbial measurement apparatus 10 is formed into a plurality of slits 121 of the upper surface part 112. It is introduced into the first housing 110 through the.
공기는 상기 다수의 슬릿(121)을 통과하는 과정에서, 좁은 유로 단면적에 의하여 유속이 증가될 수 있다. 상기 다수의 슬릿(121)을 통과한 공기 중 입자가 상대적으로 큰 부유 미생물 입자는 상기 노즐부(120)의 입구부(125a)를 통하여 상기 내부유로(125)에 유입된다(도 5의 C).As air passes through the plurality of slits 121, the flow velocity may be increased by a narrow passage cross-sectional area. Floating microbial particles having a relatively large amount of air particles passing through the plurality of slits 121 are introduced into the internal passage 125 through the inlet portion 125a of the nozzle unit 120 (FIG. 5C). .
그리고, 상기 부유 미생물 입자들은 상기 출구부(125b)를 통하여 상기 내부유로(125)에서 배출된 후, 상기 미생물 입자유로(127)를 유동하게 된다.In addition, the suspended microbial particles are discharged from the internal passage 125 through the outlet portion 125b, and then flow through the microbial particle passage 127.
반면에, 상기 다수의 슬릿(121)을 통과한 공기 중 입자가 상대적으로 작은 공기 입자들은 진행방향이 꺽이면서 상기 내부유로(125)로 유동하지 못하고, 상기 노즐부(120)의 외측 공간을 따라 유동하게 된다(도 5의 B).On the other hand, air particles having relatively small particles in the air passing through the plurality of slits 121 do not flow to the inner passage 125 while the traveling direction is bent, and is along the outer space of the nozzle unit 120. It will flow (B of FIG. 5).
그리고, 상기 공기 입자들은 상기 공기입자 유로(129)를 유동하여, 상기 송풍팬(150)을 통과하게 된다.In addition, the air particles flow through the air particle passage 129 to pass through the blowing fan 150.
정리하면, 좁은 단면적의 노즐을 통하여 공기가 유동하는 과정에서, 상대적으로 큰 부유 미생물 입자는 상기 입구부(125a)를 통하여 상기 내부유로(125)로 유입되며, 상대적으로 작은 공기 입자는 상기 슬릿(121)과 입구부(125a) 사이의 이격된 공간을 통하여 유동방향(stream line)이 꺽이도록 유동될 수 있다. In summary, in the process of flowing air through a nozzle having a narrow cross-sectional area, relatively large floating microbial particles are introduced into the internal passage 125 through the inlet portion 125a, and relatively small air particles are introduced into the slit ( The stream line may be bent through the spaced space between 121 and the inlet 125a.
이와 같은 입자 분류구조를 가상 임팩터(virtual impactor) 구조라 이름할 수 있으며, 본 실시예는 상기 가상 임팩터 구조를 적용하여 부유 미생물 입자와 공기 입자가 용이하게 분류될 수 있다.Such a particle classification structure may be referred to as a virtual impactor structure.

이와 같이, 필터 구동부(250)의 구동에 의하여, 미생물 입자가 포집된 필터부(220)의 일 영역은 상기 수광부(320)를 향하도록 위치 이동될 수 있다. 결국, 필터 케이스(210) 및 필터부(220)가 회전 가능하게 제공되어, 미생물 포집 및 발광 과정이 자동적으로 이루어질 수 있다는 효과가 있다.As such, by driving the filter driver 250, one region of the filter part 220 in which the microbial particles are collected may be moved to face the light receiving part 320. As a result, the filter case 210 and the filter unit 220 are rotatably provided, so that the microbial collection and light emission process can be automatically performed.

그리고, 상기 수광부(320)는 미생물 입자가 상기 필터부(220)에 포집되기 이전에, 상기 필터부(220)의 발광량을 감지하기 위하여 작동될 수 있다. 이 때의 발광량은 추후 미생물 입자가 포집되었을 때의 발광량에 대한, 기준정보를 제공하는 점에서, "기준 발광량"이라 이름할 수 있다.In addition, the light receiving unit 320 may be operated to detect the amount of light emitted from the filter unit 220 before the microbial particles are collected in the filter unit 220. The light emission amount at this time may be referred to as "reference light emission amount" in that it provides reference information on the light emission amount when the microbial particles are collected later.
