Description
本発明は、吐出モードを切替え可能な吐出ヘッド及び吐出器に関する。 The present invention relates to a discharge head and a discharger capable of switching a discharge mode.
泡及び霧を切り替え可能な吐出器として、押下げヘッド式ではないが、霧放出用のノズル孔の外側に発泡筒を筒軸を水平にして設け、この発泡筒を内外方向に進退させ、或いは発泡筒を回転させることで、霧が発泡筒の内面に衝突して発泡しかつ霧が発泡筒内をそのまま通過するように設けたものが知られている（特許文献１〜２）。 As a discharger capable of switching between foam and mist, it is not a push-down head type, but a foam cylinder is provided outside the mist discharge nozzle hole with the cylinder axis horizontal, and this foam cylinder is advanced and retracted inward and outward, or It is known that a mist collides with the inner surface of a foamed cylinder by rotating the foamed cylinder and foams and the mist passes through the foamed cylinder as it is (Patent Documents 1 and 2).
特許文献１〜２の吐出モード変更機構は、トリガー式の吐出器を前提としており、押下げ式の吐出ヘッドの吐出モード切替に関しては何も提案していない。仮に水平な軸周りを回転し、または軸方向に進退する発泡筒を、押下げ式の吐出ヘッドに設けるとすると、このヘッド部分が嵩張り、必ずしも好適ではない。 The discharge mode changing mechanism of Patent Documents 1 and 2 is based on a trigger-type discharger, and does not propose anything regarding discharge mode switching of a push-down type discharge head. If a push-down type discharge head is provided with a foam cylinder that rotates around a horizontal axis or advances and retreats in the axial direction, this head portion is bulky and not necessarily suitable.
また吐出モード変更機構は、一つの吐出口を霧及び泡放出用に兼用しているが、例えば設計仕様や用途によっては、極め細かい泡を放出できるメッシュ付きの発泡筒を用いたい場合がある。 The discharge mode changing mechanism also uses one discharge port for both mist and foam discharge. For example, depending on design specifications and applications, there is a case where it is desired to use a foamed cylinder with a mesh that can discharge extremely fine bubbles.
本願発明の第１の目的は、押下げ式の吐出ヘッドのヘッド本体に吐出モードの異なる複数の吐出口を設け、ヘッド本体に対してカバー部材を回転させることで、吐出口を選択することが可能な吐出ヘッド及び吐出器を提供することである。 A first object of the present invention is to select a discharge port by providing a plurality of discharge ports with different discharge modes in a head body of a push-down type discharge head and rotating a cover member with respect to the head body. It is to provide a possible ejection head and dispenser.
本発明の第２の目的は、複数の吐出口の一つを選択したときに残りの吐出口に至る吐出用の通路を確実に閉鎖することが可能な吐出ヘッド及び吐出器を提供することである。 A second object of the present invention is to provide a discharge head and a discharger capable of reliably closing a discharge passage reaching the remaining discharge ports when one of a plurality of discharge ports is selected. is there.
