본 고안은 화생방전시 또는 기타의 유독성가스로부터 인체를 보호할 목적으로 사용되는 방독마스크에 부설하여, 마스크를 착용한 상태에서의 대화를 위한 전성(轉聲)작용과 호흡을 위한 배기작용을 하나의 장비로서 겸용할 수 있게 구성한 방독마스크용 전성배기변에 관한 것이다.The present invention is installed in a gas mask used for the purpose of protecting the human body from a metabolic discharge or other toxic gases. The present invention relates to a flue mask for gas masks configured to be used as equipment.

종래에 사용되고 있는 방독마스크에 있어서는 일반적으로 호흡 작용을 위한 흡기변과 배기변만을 설치하고 있는 것이 보통이나 이와 같은 방독마스크는 마스크를 착용한 상태에서 외부로 소리를 전달할 수 있는 소위 전성수단이 설치되어 있지 않기 때문에 대화를 나눌 수 없는 폐단이 있는 것이다. 이와 같은 폐단을 시정하고 전성과 배기를 함께 할 수 있게 하기 위해서 마스크에 배기변과 별도로 전성장치를 배기변에 인접하여 설치한 방독마스크가 근래에 개발이용되고 있으나 이러한 방독마스크의 경우에는 그 면적이 극히 한정되어 있는 마스크의 정면하위부에 별개로 제작된 배기변과 전성장치를 각각 배치하게 되므로서 그 제작 및 조립공정이 복잡해질뿐 아니라 배기변 및 전성장치의 크기도 자연히 제한을 받게되어 배기성능과 전성성능이 양호하지 못한 결점이 있다.In the gas masks used in the related art, in general, only intake and exhaust valves for respiratory action are generally provided. However, such masks are provided with so-called electrical means for transmitting sound to the outside while wearing a mask. There is a dismissal that we cannot talk to because we do not. In order to rectify the closed end and allow both the electric and the exhaust, both the gas mask and the gas mask installed in the mask adjacent to the exhaust valve are developed and used in recent years. Exhaust valves and solenoids, which are manufactured separately, are arranged in the lower part of the front and bottom of the mask, which is extremely limited. Therefore, the manufacturing and assembly process is complicated, and the size of the exhaust valves and the solenoids is naturally limited. There is a drawback of poor performance.

본 고안은 그와 같은 점을 감안하여 상기한 바와 같은 두개의 기능 즉 배기기능과 전성기능을 하나의 장치로 겸할 수 있게 하므로서 제작 및 조립의 간편 내지는 간소화를 도모하는 동시에 배기작용과 전성작용의 성능을 향상시킬 수 있게 안출한 것인바, 그 구조와 작용효과를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.In consideration of such a point, the present invention enables the two functions as described above, that is, the exhaust function and the malleable function, to be combined into a single device, thereby facilitating or simplifying the manufacture and assembly, and at the same time, the performance of the exhaust and the malleability It is devised to improve the bar, the structure and the effect will be described in detail by the accompanying drawings as follows.

제2도에 도시하고 있는 바와 같이, 원통형으로 된 배기변본체(1)의 전면외주연부 내측에 환상요홈(2)을 형성하고, 그 환상요홈(2)의 안쪽으로는 중앙부를 향하여 외측으로 경사진 원추상부(1')와 그 중앙부에 원통부(1'')를 각각 일연체로 형성하되 원추상부(1')에는 방사상으로 다수의 배기공(3)들을 천설하고, 원통부(1'')의 측주벽에는 나선홈(4)을 형성하는 한편 원통부(1'')의 정면에는 다수의 통공(5)들을 방사상으로 천설하고있다.As shown in FIG. 2, the annular recess 2 is formed inside the front outer periphery of the cylindrical exhaust valve body 1, and the inner recess 2 is inclined outward toward the center. The cylindrical portion 1 'and the cylindrical portion 1' 'are formed in the central portion of the conical portion 1', respectively, in the conical portion 1 'radially laid out a plurality of exhaust holes (3), cylindrical portion (1') The side circumferential wall of ') forms a spiral groove 4, and a plurality of through holes 5 are radially laid in front of the cylindrical portion 1' '.

이와 같이 형성된 본체(1)의 내부에는, 그 본체(1)보다 직경이 작고 또한 상기한 본체(1)의 원통부(1'')에 나합되도록 측주벽에 나선홈(6)을 형성한 원통부(7')가 전면중앙부에 일체로 형성되고 그 원통부(7')의 전면에는 다수의 통공(8)이 천설된 전성통(7)을 끼워서 본체(1)의 원통부(1'')에 전성통(7')의 원통부(7')가 나착고정되게 하는 동시에, 그 전성통(7)의 외벽과 본체(1)의 내벽사이에 배기통로(9)가 형성되게하고, 전성통(7)의 단연부에는 감합부(7″)를 절곡형성하여 그 내부에 다수의 통공(10)을 갖인 유공보호판(11)과 진동판(12)을 고무로 된 환상지지체(13)와 함께 감삽하여 지지고정시킨다. 그리고 본체(1)의 환상요홈(2)내에는 내측모서리에 환상익변(14)이 일체로 형성된 고무제 변체(15)를 감삽하고 고정환(16)으로 고정시켜서 그 환상익변(14)의 단연부가 전성통(7)의 외주면에 밀접되어 있게한 구조이다. 도면중 미설명부호(17)은 유공보호판이다.The cylindrical body in which the spiral groove 6 was formed in the side circumference wall in the inside of the main body 1 formed in this way is smaller in diameter than the main body 1, and is joined to the cylindrical part 1 "of the said main body 1 mentioned above. The portion 7 'is integrally formed in the front center portion, and the cylindrical portion 1' 'of the main body 1 is inserted in the front surface of the cylindrical portion 7' by inserting a malleable tube 7 in which a plurality of through holes 8 are laid. The cylindrical portion 7 'of the malleable cylinder 7' is fixed and fixed, and the exhaust passage 9 is formed between the outer wall of the mallet 7 and the inner wall of the main body 1, The perforated portion 7 ″ of the barrel 7 is bent to form a fitting portion 7 ″ having a plurality of through holes 10 therein, and a hole supporting plate 11 and a diaphragm 12 together with the annular support 13 made of rubber. Fix by supporting. In the annular recess 2 of the main body 1, the rubber deformable body 15 in which the annular blade edge 14 is integrally formed on the inner edge is subtracted and fixed by a fixed ring 16 so that the edge of the annular blade edge 14 is fixed. It is a structure made to be in close contact with the outer peripheral surface of the malleable body (7). Unexplained reference numeral 17 in the drawings is a hole protection plate.

이와 같이 구성된 배기변을 제1도에 도시한 바와 같이 통상의 방독마스크 (18)의 전면입부위에 부설하여 사용케되는 것이다.As shown in FIG. 1, the exhaust valve configured as described above is used to be installed at the front entrance of the conventional gas mask 18. FIG.

본 고안은 상술한 바와 같이 구성디어 있으므로 방독마스크(18)를 착용하였을때 호흡작용에 의한 배기는 제2도의 화살표 표시와 같이 본체(1)와 전성통(7)사이의 배기통로(9)를 통하여 환상익변(14)을 열고 배기공(3)으로 배출되며, 반대로 흡기시에는 환상익변(14)이 전성통(7)에 밀접되어 배기통로(9)를 폐쇄하는 동시에 별도로 설치된 흡기변(가)에 의하여 흡기작용을 하게되며, 마스크(18)를 착용한 상태에서 말을하게되면 진동판(12)의 울림작용에 의한 진동음이 전성통(7)의 원통부 (7') 전면에 천설된 통공(8)과 본체(1)의 원통부(1'') 전면에 천설된 통공(5)을 통하여 외부로 방출되어 대화를 할 수 있게되는 것이다.Since the present invention is constructed as described above, when the gas mask 18 is worn, the exhaust gas due to the respiratory action is formed in the exhaust passage 9 between the main body 1 and the malleable tube 7, as indicated by the arrow of FIG. The annular blade side 14 is opened to be discharged to the exhaust hole 3. On the contrary, the intake valve side 14 is close to the malleable tube 7 to close the exhaust passage 9 and at the same time, a separate intake valve is provided. ) And the inhalation action is performed, and when the mask 18 is worn, the sound of vibration caused by the ringing action of the diaphragm 12 is installed in the entire surface of the cylindrical portion 7 'of the electric barrel 7. (8) and the through-hole 5 installed in the front of the cylindrical portion (1 '') of the body (1) is to be released to the outside to be able to talk.

이와 같이 본 고안은 배기변본체의 내부에 전성통을 내장하고 그 배기변본체와 전성통사이에 배기통로와 환상익변을 설치하여 배기작용과 전성작용을 겸할 수 있게 구성하였으므로 그 구조가 간단하여 제작 및 조립이 간편 용이할뿐 아니라 작은 면적을 이용하면서도 배기구와 진동판의 크기를 크게 할 수 있어서 배기 및 전성성능을 크게 향상시킬 수 있는 효과가 있다.In this way, the present invention has a simple structure because the built-in main body inside the exhaust main body and the exhaust path and the annular blade side are installed between the main main body and the main main body. And as well as easy to assemble, while using a small area can be enlarged the size of the exhaust port and the diaphragm has an effect that can greatly improve the exhaust and the whole performance.
