In the following description of the present invention, if it is determined that the detailed description of the related known technology may obscure the gist of the present invention, the detailed description thereof will be omitted.
이하 첨부된 도면을 참조하여 본 발명의 일 실시예를 상세하게 설명한다. Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
본 발명은 날숨이 연결호스를 통해 필터로 역류하는 것을 방지하여, 항상 신선한 공기로 호흡할 수 있다. The present invention prevents exhalation backflow into the filter through the connecting hose, it is always possible to breathe in fresh air.
이러한 본 발명에 따른 코마스크에 배기밸브를 구비한 미세먼지 제거 호흡기는 도 1에 도시한 바와 같이, 코마스크(10), 필터(20) 및 연결호스(30)로 이루어지고, 코마스크(10)에는 배기밸브(11)가 설치되어 있다. As shown in FIG. 1, the fine dust removing respirator having an exhaust valve in the comask according to the present invention includes a comask 10, a filter 20, and a connection hose 30, and a comask 10. ), An exhaust valve 11 is provided.
상기 배기밸브(11)는 배기구(11o)의 바깥쪽에 설치되고, 배기구와 코삽입부(11n) 사이에는 배기로(11r)가 형성되어 있으며, 배기로(11r)는 도 2 및 도 3에 도시한 바와 같이, 배기구(11o)를 향하며 점차 좁아지도록 형성되어 있다. The exhaust valve 11 is provided outside the exhaust port 11o, and an exhaust path 11r is formed between the exhaust port and the nose inserting portion 11n, and the exhaust path 11r is shown in FIGS. 2 and 3. As described above, it is formed to gradually narrow toward the exhaust port 11o.
상기 배기로(10r)가 배기구(10o)를 향하며 점차 좁아지게 형성됨으로, 날숨이 배기로를 통과할 때, 배기구를 향하며 점차 공기의 배출 속도가 빨라지고, 이렇게 빨라진 공기의 속도에 의해 배기로(10r) 내부의 공기압력이 낮아지게 된다. Since the exhaust passage 10r is gradually narrowed toward the exhaust port 10o, when exhalation passes through the exhaust passage, the exhaust speed of the air gradually increases toward the exhaust port, and the exhaust passage 10r is caused by the speed of the air so fasted. ) The air pressure inside is lowered.
상기 배기로(11r)의 공기압력이 낮아지면, 연결호스(30) 내부의 공기는 상대적으로 압력이 낮은 배기로 측으로 이동하게 됨으로, 날숨시 날숨 공기가 연결호스를 통해 필터로 역류하는 것이 방지되는 것이다.(도 3 참조)When the air pressure of the exhaust passage (11r) is lowered, the air inside the connection hose 30 is moved to the exhaust passage with a relatively low pressure, which prevents the exhalation of the exhaled air back to the filter through the connection hose (See Figure 3).
상기 코마스크(11)는 호흡할 때 변형되어 찌그러지면 호흡에 악영향을 줄수 있으므로, 딱딱한 수지나 금속으로 제작된다. 이렇게 딱딱한 재질로 만들어진 코마스크(10)의 코삽입부(10n)를 코구멍에 삽입할 경우, 코에 이물감을 줄 뿐만 아니라, 코 내부에 상처가 생길 수 있으며, 코와 코삽입부(10) 사이에 틈이 생길 수 있다. Since the comask 11 is deformed and crushed when breathing, it may adversely affect breathing, so that the comask 11 is made of hard resin or metal. When the nose insert 10n of the nose mask 10 made of the hard material is inserted into the nose hole, not only the nose feels foreign matter but also a wound may occur inside the nose, and the nose and the nose insert 10 There may be gaps in between.
이에 상기 코마스크의 코삽입부(10n)에는 연질의 합성수지나 고무로 만들어진 밀폐캡(12)을 설치하였다. Accordingly, the nose insert portion 10n of the comask is provided with a sealing cap 12 made of soft synthetic resin or rubber.
상기 밀폐캡(12)은 코와 코삽입부(10n) 사이에 틈이 생기지 않게 하여, 여과되지 않은 외부의 공기가 코로 흡입되는 것을 방지함은 물론, 코 내부에 이물감을 적게 주기 위한 것이다.
