The relationship between the diameter φC and the outer diameter φB of the intake cylinder 5 is shown as φ
C>φA>φB, and the intake hole cover 3 can be molded using only a male mold and a female mold.
しかしてガンタイプのヘアードライヤ本体１の後端部の
吸気孔２に吸気孔カバー３の嵌着筒部９を嵌着し、ヘア
ードライヤ本体１のスイッチをオンにするとファンが回

出されることになる。When the fitting cylinder part 9 of the air intake hole cover 3 is fitted into the air intake hole 2 at the rear end of the gun-type hair dryer body 1 and the switch of the hair dryer body 1 is turned on, the fan rotates and the air intake hole is turned on. Air is sucked in from the intake hole 2 through the cover 3, and hot air is blown out from the front end of the hair dryer body 1.
この時空気は吸気孔カバー３の吸気筒５のみから吸い込
まれるのみならず風ガイド筒４と吸気筒５との間に設け
た風導入孔８からも吸い込まれ、吸気面積が大となって
風量を高めることができる。At this time, air is sucked in not only from the intake cylinder 5 of the intake hole cover 3, but also from the wind introduction hole 8 provided between the wind guide cylinder 4 and the intake cylinder 5, increasing the intake area and increasing the air volume. can be increased.
しかも吸い込まれた空気は風ガイド筒４に沿ってスムー
ズに流れるため吸気時の騒音が生じないものである。Moreover, the sucked air flows smoothly along the wind guide tube 4, so no noise is generated during intake.

ないという利点がある。In the present invention, since the wind guide tube is integrally provided with the intake hole cover, the number of parts can be reduced, the time for assembling the hair dryer can be shortened, and the mold for forming the intake hole cover can be reduced. This has the advantage that the intake cylinder can be reduced in size, and since the intake cylinder is provided in the center of the wind guide cylinder and the air introduction hole is provided between the outer peripheral surface of the intake cylinder and the inner peripheral surface of the wind guide cylinder, the intake cylinder It also has the advantage of being able to suck in air from the air intake hole, increasing the intake area and increasing the amount of air blown by the hair dryer.Furthermore, the diameter becomes smaller as it goes inward. An intake cylinder is provided in the center of the wind guide cylinder, which has a generally morning glory shape, and a wind introduction hole is provided between the outer peripheral surface of the intake cylinder and the inner peripheral surface of the wind guide cylinder, so that all the air flows into the wind guide cylinder. It has the advantage that it flows smoothly along the line and makes no noise even though the amount of intake air has increased.
