【0013】 [0013]
この電動ファン付き呼吸用保護具は、次のように組み立てられる。 The electric fan with respiratory protective equipment is assembled in the following manner.
本体ケーシング6の裏面側ケース4内にファンユニット1を、そのモータ8を表面側に向けて設置する。 The fan unit 1 on the back side casing 4 of the main body casing 6, is placed toward the motor 8 on the surface side.
次いで、ファンユニット1の表面にダクト7を被せ、ダクト7の一端に形成されたフィン17をファンユニット1のダクト係止溝9へ係合する。 Then, put the duct 7 to the surface of the fan unit 1, to engage fins 17 formed on one end of the duct 7 to the duct locking groove 9 of the fan unit 1. ダクト7の一端部外周には予め押圧リング11を嵌合し、押圧リング11の取付片23にネジ12を挿通してある。 At one end the outer periphery of the duct 7 engaged previously fitted a pressing ring 11, are inserted through the screw 12 to the mounting piece 23 of the pressure ring 11.
さらに、ネジ12をファンユニット1のネジ筒10にねじ込んで、押圧リング11でフィン17を押さえると、ダクト係止溝9の底面に形成された突条20がフィン17の端面にくい込んで、ダクト7の一端とファンユニット1の吸込口2とが密封状態で圧着される。 Furthermore, the screw 12 is screwed into the screw cylinder 10 of the fan unit 1, when pressing the fin 17 with the pressure ring 11, ridges 20 formed on the bottom surface of the duct locking groove 9 bite into the end surface of the fins 17, the duct 7 one end and inlet 2 of the fan unit 1 is pressed in a sealed state.
【0014】 [0014]
次に、裏面側ケース4及びダクト7の表面に表面側ケース5を被せ、表面側ケース5の透孔15の奥端部に形成されたダクト係止鍔16と、ダクト7の分岐部18の先端に形成された係合溝19とをそれぞれ係合する。 Next, put the surface side case 5 on the surface of the rear case 4 and the duct 7, the duct engagement flange 16 formed on the inner end of the through hole 15 of the front side case 5, the duct 7 branches 18 respectively engage the engagement groove 19 formed in the tip.
その後、表面側ケース5の透孔15にそれぞれ濾過材3の基部を挿入すると、ダクト7の分岐部18の先端(係合溝19より先の部分)が濾過材3の端面と表面側ケース5のダクト係止鍔16とで挟み付けられて、濾過材3と本体ケーシング6との接合部におけるパッキングとなり、また、濾過材3の押圧突条21がダクト7の分岐部18の先端面にくい込んで、濾過材3と本体ケーシング6とが密封状態で圧着され、濾過材3とファンユニット1の吸込口2が筒状のダクト7で連結される。 Thereafter, when each inserting the base portion of the filtration media 3 into the through hole 15 of the surface-side case 5, the end face and the surface-side case 5 tip (previous section from the engaging groove 19) of filtering material 3 branches 18 of the duct 7 is clamped between the duct engagement flange 16 becomes a packing at the junction between the filtration member 3 and the body casing 6, also, the pressing protrusion 21 of the filtration material 3 bite into the distal end surface of the branch portion 18 of the duct 7 in the filtered material 3 and the body casing 6 is crimped in a sealed state, the suction port 2 of the filter material 3 and the fan unit 1 is connected by a cylindrical duct 7.
【0015】 [0015]
なお、ダクト7の他端部に3本以上の分岐部18を形成して、分岐部18に接続される濾過材3の数を増加することも可能である。 Incidentally, by forming a second end portion in three or more branches 18 of the duct 7, it is also possible to increase the number of filtering material 3 which is connected to the branch portion 18.
また、ダクト7の素材としては、硬度30°〜70°程度の弾力を有するものであれば、アクリルゴム、ニトリルゴム等のシリコーンゴム以外のものを用いることもできる。 Further, as the material of the duct 7, as long as it has elasticity hardness of around 30 ° to 70 °, it can also be used other than silicone rubber such as acrylic rubber, nitrile rubber.
