58 is a water intrusion prevention wall, and water dripping from the water guide cylinder 14 (between the standing cylinder 13 of the mounting cylinder and the inner cylinder 72 of the nozzle head described below) enters the air cylinder 24 through the outside air introduction hole 57. This is to prevent the outside air introduction hole 57 from rising.
In FIG. 2, the outside air introduction hole 57 is erected from a part of the periphery, that is, from the periphery excluding the outside periphery of the outside air introduction hole 57. Therefore, the outside air introduction hole 57 is formed in a U shape or a C shape. At that time, the water intrusion prevention wall portion rising from the inner peripheral edge of the outside air introduction hole 57 is formed in a U-shape in a top view in which the central portion is bent in the direction of the water guide tube 14.

Provided.
６０は空気用ピストン５０の嵌合筒５５を摺動自在に挿通して起立筒１３内に達するステムで、ステム嵌合筒３１の外面へ下部を嵌着させたステム上部内に吐出弁６２を設けて、吐出弁６２より上方部分を気液混合室６３に形成し、さらにステム上部外面に、周縁に突条が周設された環状座部６４をフランジ状に張出している。 Reference numeral 60 denotes a stem that slidably passes through the fitting cylinder 55 of the air piston 50 and reaches the standing cylinder 13. A discharge valve 62 is provided in the upper part of the stem that is fitted to the outer surface of the stem fitting cylinder 31. An upper part of the gas-liquid mixing chamber 63 is formed above the discharge valve 62, and an annular seat part 64 having a protrusion on the periphery is extended in a flange shape on the outer surface of the upper part of the stem.
７０はノズルヘッドで、頂壁７１から内外２重筒７２、７３を垂下して、内筒７２の下部を縮径することで中内径部に、かつ中内径部の下端部を縮径することで小内径部に、それぞれ形成し、該小内径部を空気用ピストン５０の嵌合筒５５の上部外面へ摺動自在に嵌合させる。一方、外筒７３はその下端部を起立筒１３上端へ摺動自在に嵌合させる。 A nozzle head 70 hangs down the inner and outer double cylinders 72 and 73 from the top wall 71 and reduces the diameter of the lower portion of the inner cylinder 72 to reduce the diameter of the inner diameter portion and the lower end portion of the inner diameter portion. The small inner diameter portions are respectively formed, and the small inner diameter portions are slidably fitted to the upper outer surface of the fitting cylinder 55 of the air piston 50.

It is a mesh ring that makes the liquid mixture fine bubbles.
次に作用について説明する。
初期姿勢の状態からノズルヘッド７０を押し込むと、ステム６０、液用ピストン３０、吸込弁４０が下降する。一方、空気用ピストン５０の嵌合筒５５はノズルヘッド７０の内筒７２に対して僅かにスライド可能となっているため、ノズルヘッド７０の初期の押込みでは空気用ピストン５０は静止状態を保持する。このためステム６０と一体の環状座部６４が垂下筒５６の下端から離間する。
Next, the operation will be described.
When the nozzle head 70 is pushed in from the initial posture, the stem 60, the liquid piston 30, and the suction valve 40 are lowered. On the other hand, since the fitting cylinder 55 of the air piston 50 is slightly slidable with respect to the inner cylinder 72 of the nozzle head 70, the air piston 50 remains stationary when the nozzle head 70 is initially pushed. . For this reason, the annular seat 64 integrated with the stem 60 is separated from the lower end of the hanging cylinder 56.
さらなる押込みヘッド７０の押し込みで、内筒７２下端が空気用ピストン５０の天面壁５４へ当接すると、空気用ピストン５０は下降を開始して空気用シリンダ２４内の空気を加圧する。この加圧空気は、垂下筒５６と環状座部６４との間から垂下筒５６内に流入し、ステム６０外面の空気路およびジェットリング８０とステム６０上端との間隙を介して気液混合室６３内へ流入する。 When the lower end of the inner cylinder 72 comes into contact with the top wall 54 of the air piston 50 by further pressing of the pushing head 70, the air piston 50 starts to descend and pressurizes the air in the air cylinder 24. This pressurized air flows into the drooping cylinder 56 from between the drooping cylinder 56 and the annular seat 64, and a gas-liquid mixing chamber through an air passage on the outer surface of the stem 60 and a gap between the jet ring 80 and the upper end of the stem 60. 63 flows into.
他方、ノズルヘッド７０の押し込みで、吸込弁４０は下降して液用シリンダ２５の下端部内面に接触して吸込孔を閉じると共に、吸込弁４０の下降が停止するため、液用ピストン３０のステム嵌合筒３１上端が吸込弁４０の下方小径のテーパ筒から離間して液用ピストン３０が下降するため液用シリンダ２５内の液体が加圧される。この加圧液体は弁棒４１の外面の流路、吸込弁４０上端の外面とステム嵌合筒３１内面との間隙、および吐出弁６２を介して気液混合室６３内へ流入して加圧空気と合流し、気液混合状態でジェットリング８０、メッシュリング８１を通り、泡状になってノズルヘッド７０から吐出する。
On the other hand, when the nozzle head 70 is pushed in, the suction valve 40 is lowered to contact the inner surface of the lower end of the liquid cylinder 25 to close the suction hole, and the lowering of the suction valve 40 is stopped, so that the stem of the liquid piston 30 is stopped. Since the upper end of the fitting cylinder 31 is separated from the small diameter tapered cylinder below the suction valve 40 and the liquid piston 30 is lowered, the liquid in the liquid cylinder 25 is pressurized. This pressurized liquid flows into the gas-liquid mixing chamber 63 through the flow path on the outer surface of the valve rod 41 , the gap between the outer surface of the upper end of the suction valve 40 and the inner surface of the stem fitting cylinder 31, and the discharge valve 62, and pressurizes. It merges with air, passes through the jet ring 80 and the mesh ring 81 in a gas-liquid mixed state, becomes a foam, and is discharged from the nozzle head 70.
ノズルヘッド７０の押込みを解除すると、コイルスプリング４２のばね力で液用ピストン３０、吸込弁４０、ステム６０、ノズルヘッド７０が上昇する。一方、空気用ピストン５０の嵌合筒５５はノズルヘッド７０の内筒７２に対して僅かにスライド可能となっているため、空気用ピストン５０は静止状態を保持する。このためステム６０と一体の環状座部６４が垂下筒５６の下端へ当接する。これにより空気用ピストン５０は上昇するため、空気用シリンダ２４内は負圧化し、バルブ５９が天面壁５４から下方へ離間するため、外気導入孔５７から空気が導入される。他方、吸込弁４０が上昇して吸込孔が開になるため、液用シリンダ２５内の負圧化により吸込孔を介して容器本体の内容物が液用シリンダ２５内へ吸引される。 When the pushing of the nozzle head 70 is released, the liquid piston 30, the suction valve 40, the stem 60, and the nozzle head 70 are raised by the spring force of the coil spring 42. On the other hand, since the fitting cylinder 55 of the air piston 50 is slightly slidable with respect to the inner cylinder 72 of the nozzle head 70, the air piston 50 remains stationary. For this reason, the annular seat 64 integrated with the stem 60 abuts against the lower end of the hanging cylinder 56. As a result, the piston 50 for air rises, the inside of the cylinder 24 for air becomes negative pressure, and the valve 59 separates downward from the top wall 54, so that air is introduced from the outside air introduction hole 57. On the other hand, since the suction valve 40 is raised to open the suction hole, the negative pressure in the liquid cylinder 25 causes the contents of the container body to be sucked into the liquid cylinder 25 through the suction hole.
一方、起立筒１３とノズルヘッド７０の内筒７２との間隙内に入った水はフランジ状頂壁１２の内面沿いに移動することなく、導水筒１４下端から天面壁５４上へ滴下して、天面壁の外周縁へと移動するが、水浸入防止壁５８が設けられているため、外気導入孔５７を介して空気用シリンダ２４内へ浸入することがない。 On the other hand, the water that has entered the gap between the upright cylinder 13 and the inner cylinder 72 of the nozzle head 70 does not move along the inner surface of the flange-like top wall 12, but drops from the lower end of the water guide cylinder 14 onto the top wall 54, Although it moves to the outer peripheral edge of the top wall, since the water intrusion prevention wall 58 is provided, it does not enter the air cylinder 24 through the outside air introduction hole 57.
