【発明の属する技術分野】
本発明は、防毒マスクの有機ガス用吸収缶の交換時期を着用している装着者に知らせる交換時期検知装置を取り付けた防毒マスクに関する。
【０００２】
【従来技術】
防毒マスクには汚染された空気中の有害物質を吸着もしくは中和または触媒作用によって無毒化する吸収剤が収納されている吸収缶が設けられている。そして、吸収缶内の吸収剤の残存能力を知り、吸収缶の交換時期、即ち、使用限界を知ることは極めて重要なことである。そのため、吸収缶の破過を知るために種々の提案がなされている。例えば、吸収缶に検知紙又は検知管を組み込み，ガスとの反応による変色から吸収缶の限界を知る方法や、防毒マスクに電子回路を利用したセンサーを組込み、吸収缶の交換時期に達したことを知らせる方法等があるが、何れも個々のガスに対する吸収缶の破過を検出しようとしていたため実用化されているものはない。
【０００３】
【発明が解決しようとする課題】
このような事情のもとで、本発明者は有機ガス用吸収缶の交換時期を容易に知らせる交換時期検知装置を種々検討した結果、本発明を完成したもので、本発明の目的は有機ガス用吸収缶に取付可能な交換時期検知装置を提供する。
【０００４】
【課題を解決するための手段】
本願の請求項１の発明は 有機ガス用吸収缶の交換時期検知装置を有する防毒マスクにおいて、該防毒マスクの材質はＮＢＲ、天然ゴム、塩化ビニル又は熱可塑性プラスチックからなる群から選ばれたガスセンサーに影響を与えない材質で構成され、且つ、前記交換時期検知装置はＬＥＤ等の発光体を着用者が見やすい防毒マスクの一部に取りつけを組み込んであると共にガスセンサーを組み込んだアダプターを有し、該ガスセンサーはトルエンの濃度が１０〜３０ｐｐｍの場合に相当する有機物質に対して警報を発することを特徴とする塗装用防毒マスクである。また、請求項２の発明は、有機ガス用吸収缶の交換時期検出装置を有する塗装用防毒マスクにおいて、前記交換時期検出装置はガスセンサーを組み込んだアダプターを有するものであって、且つ、前記アダプターを防毒マスクと有機ガス用吸収缶の間に取り付けられていることを特徴とする塗装用防毒マスクである。請求項３の発明はガスセンサーの交換が可能な吸収缶の交換時期を知らせることを特徴とする塗装用防毒マスクである。そして、前記ガスセンサーが、トルエンの濃度が１０〜３０ｐｐｍの場合に相当する有機物質に対して警報を発するようなセンサーであることが好ましく、更に、ガスセンサー自体の交換が可能ことが好ましい。そして、これらの防毒マスクの材質は、ＮＢＲ、天然ゴム、塩化ビニルなどの熱可塑性プラスチックからなる群から選ばれたガスセンサーに影響を与えない材質であることが好ましい。
【０００５】
【発明の実施の形態】
以下、本発明について説明する。
本発明において使用するＬＥＤ（発光ダイオード）等の発光体を組み込んだ交換時期検知装置とはＬＥＤ等の発光体よりなる検知部と警報部とをリード線で接続した装置であって、有機ガス用吸収缶の交換時期が近づき交換時期が近いことき警報を発すると共に発光体によって着用者に知らせる装置である。そして、この装置を着用者が見やすい防毒マスクの任意の場所、例えば防毒マスクの締め紐の側方に取り付ける。
又、本発明においては他の交換時期検知装置として、センサー組み込んだアダプターを有する装置を使用する。センサーとしては熱線型半導体式センサー等からなり、破過時間に至ったときに警報を発するものが好ましい。そして、センサーはアダプターにねじ込む構造とすることが好ましい。
使用したセンサーの出力としては、一般的な塗装用には１０〜３０ｐｐｍのトルエンに反応する出力とすることが好ましい。各種有機物の破過時間に対する警報を発する時間の割合の一例を表１に示す。破過時間に対する警報を発する時間の割合は式（１）によって表され、式（１）における破過時間測定条件は国家検定に準じる。
【０００６】
【表１】
【数１】
本発明の防毒マスクは上記のＬＥＤ等の発光体を組み込んだ交換時期検知装置或いはガスセンサーを組み込んだ交換時期検知装置の何れか一方を取り付けたものでもよく、又両方の交換時期検出装置を取り付けたものでもよい。
そして、防毒マスクの材質としては特に限定されるものではないが、シリコンゴムなどのような材質はセンサーに影響を与えるので、センサーに影響のないＮＢＲ、天然ゴム、塩化ビニルなどの熱可塑性エラストマーを使用することが好ましい。
【０００９】
【実施例】
次に本発明の実施例として図面をもって具体的に示す。
図１は本発明に係る防毒マスクの側面図である。図１において、マスク１の前方にアダプター２を介して有機ガス用吸収缶３を設け、アダプター２にはセンサー４をねじ込んである。又、防毒マスク１の側方の締め紐５の近傍に発光ダイオードＬＥＤを組み込んだ検知装置７を設け、この検知装置よりリード線８をもって警報部９に繋ぎ、警報部には警報ブザーを設ける。
このような防毒マスクであるので、有機ガス用吸収缶の交換時期時期が到来したときにはがガスセンサーによって警報が発せられると共に本体から配線を用いて接続されたＬＥＤなどの発光体によって知らせ、なおかつその発光体はマスク着用者によって認識することが出来るので、着用者は確実に有機ガス用吸収缶の交換時期を知ることが出来る。
【００１０】
【発明の効果】
以上述べたように、本発明はＬＥＤ等の発光体を組み込んだ検出装置或いはガスセンサーを組み込んだアダプターを有する検出装置若しくはこの両者の検出装置を設けた防毒マスクであり、この防毒マスクは従来のものに比して有機ガス用吸収缶の交換時期を確実に感知することが出来るので、着用者に取って安全な防毒マスクである。

BACKGROUND OF THE INVENTION
The present invention relates to a gas mask equipped with a replacement time detection device that informs a wearer of the replacement time of an organic gas absorbent can of the gas mask.
[0002]
[Prior art]
The gas mask is provided with an absorption can that contains an absorbent that adsorbs, neutralizes, or catalyzes polluted harmful substances in the air. And it is very important to know the remaining capacity of the absorbent in the can and know the replacement time of the can, that is, the use limit. Therefore, various proposals have been made to know the breakthrough of the absorption canister. For example, the detector paper or detector tube is installed in the absorber, and the limit of the absorber can be determined from the discoloration caused by the reaction with the gas, or the sensor using an electronic circuit is installed in the gas mask, and the absorber can be replaced. However, none of them have been put into practical use because they tried to detect the breakthrough of the absorber for each gas.

DETAILED DESCRIPTION OF THE INVENTION
The present invention will be described below.
The replacement time detection device incorporating a light emitter such as an LED (light emitting diode) used in the present invention is a device in which a detection unit made of a light emitter such as an LED and an alarm unit are connected by a lead wire, and is used for organic gas. This is a device that issues an alarm when the time for replacement of the absorber is approaching and that the time for replacement is near, and informs the wearer by means of a light emitter. And this apparatus is attached to the arbitrary places of the gas mask which a wearer can easily see, for example, the side of the string of the gas mask.
In the present invention, as another replacement time detection device, a device having an adapter with a built-in sensor is used. As the sensor, a sensor composed of a hot-wire semiconductor sensor or the like, which issues an alarm when the breakthrough time is reached is preferable. The sensor is preferably screwed into the adapter.
The output of the sensor used is preferably an output that reacts with 10 to 30 ppm of toluene for general coating. Table 1 shows an example of the ratio of the time for issuing an alarm for the breakthrough time of various organic substances. The ratio of the time for issuing an alarm for the breakthrough time is expressed by equation (1), and the breakthrough time measurement conditions in equation (1) conform to the national test.
[0006]
[Table 1]
[Expression 1]
The gas mask of the present invention may be provided with either a replacement time detection device incorporating a light emitter such as the LED or a replacement time detection device incorporating a gas sensor, or both replacement time detection devices. May be good.
The material of the gas mask is not particularly limited, but a material such as silicone rubber affects the sensor. Therefore, a thermoplastic elastomer such as NBR, natural rubber, or vinyl chloride that does not affect the sensor is used. It is preferable to use it.
[0009]
