본 고안은 방독면용 정화통에 관한 것으로, 특히 그 부피를 줄이면서도 원하는 정화 성능을 발휘할 수 있도록 한 방독면용 정화통에 관한 것이다.The present invention relates to a gas container for gas masks, and more particularly to a gas container for gas masks that can achieve the desired purification performance while reducing its volume.
일반적으로 방독면은 제4도에 도시한 바와 같이 안면부(2)와 투시창(3)을 포함하는 본체(1)와, 상기 본체(1)에 결합되어 안면부(2)가 얼굴에 밀착되는 상태로 조여주는 머리끈(4)과, 본체(1)내부의 공기를 배출하는 배기밸브(5)와, 착용자의 음성을 외부로 전달하는 전성판(6)과, 음료수 취수구(7)와, 본체(1)의 일측에 설치되는 정화통(10)으로 구성된다.In general, the gas mask is coupled to the main body 1 including the face part 2 and the see-through window 3 and the main body 1 as shown in FIG. The head strap 4, the exhaust valve 5 for discharging the air inside the main body 1, the sole plate 6 for transmitting the wearer's voice to the outside, the drinking water intake 7 and the main body 1 It consists of a purifying container 10 is installed on one side of.
이러한 방독면은 안면부(2)를 얼굴에 밀착시켜 얼굴과 방독면 안면부(2) 사이에 완전한 밀폐구조를 만들고, 방독면을 착용한 사람의 흡입력에 따라 정화통(10)을 통과하면서 정화된 공기를 호흡함으로써 호흡기를 보호하는 것이다.This gas mask makes the face part 2 close to the face to create a complete sealing structure between the face and the gas mask face part 2, and respirator by breathing the purified air while passing through the purifying tank 10 according to the suction force of the person wearing the gas mask. To protect.
이러한 방독면에서 정화통(10)의 정화성능은 안면부(2)의 밀착성과 더불어 방독면의 특성을 결정하는 데 있어 가장 중요한 척도이다.In such gas masks, the purification performance of the clarifier 10 is the most important measure in determining the characteristics of the gas mask along with the adhesion of the face part 2.
종래 정화통(10)은 제5도 및 제6도에 도시한 바와 같이, 바닥면에 방독면 본체(1)와 결합되는 결합부(11a)를 가지는 정화통체(11)와, 이 정화통체(11)의 일측에 씌워지며 공기유입공(12a)를 가지는 덮개(12)와, 상기 바닥면측에 설치되는 활성탄(13)과 그 위에 설치되는 필터(14)로 구성된다.As shown in Figs. 5 and 6, the conventional purification vessel 10 has a purification cylinder 11 having a coupling portion 11a coupled to the gas mask body 1 at the bottom thereof, and the purification cylinder 11 Covered on one side of the cover 12 having an air inlet hole (12a), and the activated carbon 13 is installed on the bottom surface side and the filter 14 is installed on it.
상기 활성탄(13)은 그 양측에 보호망(14a, 14b)과 부직포(15a, 15b)와 다공천판(16a, 16b)이 적층되어 통기성을 살리면서도 활성탄(13)이 유출되지 않도록 되어 있다.In the activated carbon 13, protective nets 14a and 14b, nonwoven fabrics 15a and 15b, and porous top plates 16a and 16b are stacked on both sides thereof, so that the activated carbon 13 does not flow out while utilizing air permeability.
상기 필터(14)는 종이로 형성된 고효율 입자필터(HEPA Filter, High Particulate Air Filter)가 사용되며, 상기 덮개(12)와의 사이에는 스페이서(17)가 개재된다.The filter 14 is a high efficiency particulate filter (HEPA Filter) formed of paper is used, the spacer 17 is interposed between the cover 12.
이와 같이 구성된 종래의 정화통(10)에서는 활성탄(13)과 필터(14)를 2중으로 적층한 구조로서 활성탄을 그대로 장입하는 것이어서 활성탄(13)층의 두께가 두꺼워질 뿐만 아니라 활성탄(13) 입자의 유출을 방지하기 위하여 별도의 보호망(14a, 14b)과 부직포(15a, 15b) 및 다공천판(16a, 16b)를 적층하고 있기 때문에 그 전체적인 두께가 더욱 두꺼워지게 되며, 전체 무게가 무거워지므로 방독면을 착용하였을 때 행동에 지장을 주게 되는 등 불편하며, 부품수가 많아 조립생산성이 저하되고 원가상승을 초래하게 되는 등의 문제점이 있었다.In the conventional purification tank 10 configured as described above, the activated carbon 13 and the filter 14 are stacked in two layers, and the activated carbon is charged as it is, so that the thickness of the activated carbon 13 layer is not only thickened, but also In order to prevent spills, separate protective nets 14a and 14b, nonwoven fabrics 15a and 15b, and perforated top plates 16a and 16b are laminated so that the overall thickness becomes thicker and the overall weight becomes heavier. When worn, it is inconvenient to interfere with the behavior, there are a number of parts, such as assembly productivity is lowered, resulting in a cost increase.
또한 종래에는 상기 필터(14)만을 내장한 것이 있으나 이는 분진만을 여과하는 산업용으로서 화생방전용이나 시위진압용으로는 부적합한 것이었다.In addition, conventionally, only the filter 14 is incorporated, which is not suitable for chemical discharge or demonstration suppression as an industry for filtering only dust.
또 일반적으로 가스의 대분분은 미립자로 구성되어 있기 때문에 상기 필터(14)에 의하여 대부분의 가스가 여과되고, 활성탄(13)에서는 필터(14)에서 여과되지 않은 가스상 물질을 여과시켜 주면 된다는 점에 착안하여 본 고안을 완성하게 된 것이다.In general, since most of the gas is composed of fine particles, most of the gas is filtered by the filter 14, and in the activated carbon 13, the gaseous material not filtered by the filter 14 may be filtered. The idea is to complete the present invention.
본 고안의 목적은 두께와 무게를 줄여 착용시 활동에 지장을 주지 않으며 부품수를 줄여 조립생산성 향상 및 원가절감을 기할 수 있도록 한 방독면용 정화통을 제공하려는 것이다.The object of the present invention is to provide a gas mask for reducing gas thickness and weight, which does not interfere with activities when worn and reduces the number of parts, thereby improving assembly productivity and reducing costs.
이러한 본 고안의 목적을 달성하기 위하여 바닥면에 방독면 본체와 결합되는 결합부를 가지는 정화통체와, 이 정화통체의 일측에 씌워지며 공기유입공를 가지는 덮개와, 상기 정화통체의 바닥면측에 설치되며 강도 보강용 나일론 직물이 접착된 활성탄첨착 발포제와 그 위에 설치되는 필터로 구성됨을 특징으로 하는 방독면용 정화통이 제공된다.In order to achieve the object of the present invention, a purging cylinder having a coupling part coupled to the gas mask body on the bottom surface, the cover is covered on one side of the purifying cylinder and has an air inlet hole, installed on the bottom surface side of the purifying cylinder and reinforced strength Provided is a gas mask for a gas mask, characterized in that the nylon fabric is composed of an activated carbon-attached blowing agent and a filter installed thereon.
이하, 본 고안에 의한 방독면용 정화통을 첨부도면에 도시한 실시례에 따라서 상세히 설명한다.It will be described below in detail according to the embodiment shown in the accompanying drawings the gas mask for the gas mask according to the present invention.
제1도는 본 고안에 의한 정화통이 적용된 방독면을 보인 것으로, 주요 구성 부분인 본체(1), 머리끈(4), 배기밸브(5), 전성판(6), 취수구(7)등의 구성은 상술한 종래의 방독면과 동일하므로 동일 부분에 대하여는 동일 부호를 부여하고 구체적인 설명은 생략한다.Figure 1 shows a gas mask to which the purifier according to the present invention is applied, the main components of the main body 1, the head strap 4, the exhaust valve 5, the malleable plate 6, the intake port 7, etc. Since it is the same as the conventional gas masks mentioned above, the same code | symbol is attached | subjected about the same part and detailed description is abbreviate | omitted.
제1도 내지 제3도에서 20은 본 발명에 의한 정화통으로서, 바닥면에 방독면 본체(1)와 결합되는 결합부(21a)를 가지는 정화통체(21)와, 이 정화통체(21)의 일측에 씌워지며 공기유입공(22a)를 가지는 덮개(22)와, 상기 바닥면측에 설치되는 활성탄첨착 발포체(23)와 그 위에 설치되는 필터(24)로 구성된다.20 in FIG. 1 to FIG. 3, the purifying cylinder according to the present invention includes a purging cylinder 21 having a coupling part 21a coupled to the gas mask main body 1 at the bottom thereof, and one side of the purifying cylinder 21. It is composed of a cover 22 which covers the air inlet hole 22a, an activated carbon-adhered foam 23 provided on the bottom surface side, and a filter 24 provided thereon.
상기 정화통체(21)와 덮개(22)는 정화통체(21)의 두께를 종래의 것보다 얇게 형성한 것만 다르고 나머지 구조는 동일하다.The purification cylinder 21 and the cover 22 is different from the one formed by forming the thickness of the purification cylinder 21 thinner than the conventional one, and the rest of the structure is the same.
상기 정화통체(21)의 바닥면과 활성탄첨착 발포체(23)의 사이에는 위로부터 보호망(25)과 다공천판(26)의 적층 조립되며, 상기 필터(24)와 덮개(22)사이에는 스페이서(27)가 설치된다.Between the bottom surface of the purifying cylinder 21 and the activated carbon-adhered foam 23, a lamination and assembling of the protection net 25 and the porous top plate 26 are arranged from above, and a spacer is formed between the filter 24 and the lid 22. (27) is installed.
상기 활성탄첨착 발포체(23)는 폴리우레탄 발포체(Foam)가 사용된다.The activated carbon-adhered foam 23 is a polyurethane foam (Foam) is used.
활성탄첨착 발포체(23)는 활성탄을 탄 물에 발포체를 담가서 침적시키는 것에 의하여 첨착(Impregnate)하여 제조하는 것으로, 그 두께는 종래 활성탄중에 비하여 절반 이하로 줄이는 것이다.Activated carbon impregnated foam 23 is manufactured by impregnating activated carbon by dipping the foam in carbon water and depositing it, and the thickness thereof is reduced to less than half as compared to conventional activated carbon.
또한 활성탄첨착 발포체(23)는 그 기계적 강도가 낮으므로 나일론 직물을 접착시켜 보강할 수도 있는 것이다.In addition, since the activated carbon-adhered foam 23 has a low mechanical strength, the activated carbon-adhered foam 23 may be reinforced by adhering a nylon fabric.
또한 활성탄첨착 발포체(23)는 활성탄이 발포체의 셀내에 첨착되어 있는 상태이므로 활성탄이 유출되는 일이 없어 종래 사용되던 부직포와 보호망의 일부를 생략할 수 있게 된다.In addition, since the activated carbon impregnated foam 23 is in a state in which activated carbon is impregnated in a cell of the foam, activated carbon does not leak and thus a part of a nonwoven fabric and a protective net that are conventionally used can be omitted.
이상과 같이 구성된 본 고안에 의한 정화통(20)이 적용된 방독면을 착용한 상태에서 착용자가 호흡하게 되면, 공기유입공(22a)을 통하여 유입된 외부의 오염된 공기는 1차적으로 필터(24)에 의하여 대부분의 입자상 물질이 여과되고, 여과되지 않은 기체상 물질은 보호망(25)과 다공천판(26)을 통하여 활성탄첨착 발포체(23)에 도달하게 되며, 여기서 발포체를 통과하면서 이에 첨착된 활성탄에 흡착되어 여과된 후 결합부(21a)를 통하여 방독면 본체(1)내로 유입되는 것이다.When the wearer breathes while wearing the gas mask to which the purifying tank 20 according to the present invention configured as described above is applied, externally contaminated air introduced through the air inlet hole 22a is primarily applied to the filter 24. Most of the particulate matter is filtered out, and the unfiltered gaseous material reaches the activated carbon-adhered foam 23 through the protection net 25 and the porous top plate 26, where the activated carbon attached to the activated carbon is passed through the foam. After being adsorbed and filtered, the gas is introduced into the gas mask body 1 through the coupling part 21a.
이상과 같이 본 고안에 의하면 활성탄층을 사용하지 않고 활성탄첨착 발포체를 사용함으로써 그 두께와 무게를 크게 줄일 수 있으며, 활성탄의 유출이 발포체 자체에서 방지되므로 보호망과 부직포를 생략할 수 있어 부품수가 줄고 조립생산성이 향상되며, 원가절감을 기할 수 있게 되는 것이다. 또한 활성탄첨착 발포체에 강도 보강용 나일론 직물을 접착하였으므로 활성탄첨착 발포체의 강도를 높여 변형이나 파손을 방지할 수 있게 되는 것이다.As described above, according to the present invention, the thickness and weight of the activated carbon-impregnated foam can be greatly reduced without using the activated carbon layer, and since the outflow of activated carbon is prevented from the foam itself, the protection net and the nonwoven fabric can be omitted, thereby reducing the number of parts and assembling. Productivity will increase and cost will be reduced. In addition, it is possible to prevent the deformation or breakage by increasing the strength of the activated carbon-adhered foam to the nylon fabric for strength reinforcement to the activated carbon-attached foam.
