本発明の実施例に示す蓄圧噴霧装置は上述せるごとき構
造であり、次に該蓄圧噴霧装置によって容器６内の液状
体を蓄圧する場合は以下の通りである。The pressure accumulating spray device shown in the embodiment of the present invention has the structure as described above. Next, when the pressure accumulating spray device is used to accumulate the pressure of the liquid in the container 6, the procedure is as follows.
蓄圧及び噴霧を行なわないときは、ばね１３及び１４で
ピストン７は下限位置となり、ピストン棒８は逆に上限
位置となって弁体１５がオリフィス１６を閉鎖する第２
図の状態となる。When pressure accumulation and spraying are not performed, the piston 7 is at the lower limit position by the springs 13 and 14, and the piston rod 8 is at the upper limit position, so that the valve body 15 closes the orifice 16.
It will be in the state shown in the figure.
次に上記状態で操作筒１を手などで握持し、握持した状
態で該操作筒１を上下に移動させる。Next, in the above state, the operating barrel 1 is grasped with a hand or the like, and while being held, the operating barrel 1 is moved up and down.

室２０内に流入し、更にこの液状体はばね１３及び１４
に抗してピストン７を押上げる。When the operation cylinder 1 is pushed down, the piston rod 8 integrated with it also moves down, and the piston 10 at the lower end compresses the liquid in the suction compression chamber 19, and the state of the compressed liquid in the chamber 19 changes. , the outer periphery of the piston 10 is pushed open and flows into the lower pressure storage chamber 20, and this liquid also flows into the springs 13 and 14.
The piston 7 is pushed up against the

１０は吸引圧縮室１９内を上昇し、該室１９は負圧とな
るため逆止弁９は開いて、パイプ４を介して容器６内の
液状体が吸上げられる。Next, when the operation cylinder 1 is raised following the depression, the piston 10 rises in the suction compression chamber 19, and this chamber 19 becomes negative pressure, so the check valve 9 opens and the container is passed through the pipe 4. The liquid inside will be sucked up.
ピストン１０の上昇により、該ピストン１０の外周部は

密着して蓄圧室２０内の液状体は押上げられ、ばね１３
及び１４に抗してピストン７を更に上昇させるもので、
操作筒１を上下操作による蓄圧作動は第３図に示す状態
である。As the piston 10 rises, the outer periphery of the piston 10 comes into close contact with the inner wall of the suction compression chamber 19 due to self-return and the pressure of the pressure accumulation chamber 20, and the liquid in the pressure accumulation chamber 20 is pushed up, and the spring 13
and 14 to further raise the piston 7,
The pressure accumulation operation by moving the operation tube 1 up and down is the state shown in FIG.
ピストン１０の上下動により蓄圧室２０内に液状体が送
り込まれると、該液状体は横孔１８を通ってピストン棒
８の通路１７内にも流入すると共に、液状態はピストン
７を介してばね１３と１４の作用により加圧され蓄圧状
態となる。When a liquid is sent into the pressure storage chamber 20 by the vertical movement of the piston 10, the liquid also flows into the passage 17 of the piston rod 8 through the horizontal hole 18, and the liquid state is changed to the spring state through the piston 7. Due to the action of 13 and 14, the pressure is increased and the pressure is accumulated.
この場合、吸引圧縮室１９は蓄圧室２０に比して横断面
積が小さくしてあり、したがって、ピストン棒８を押下
げる際のピストン１０に掛る液圧は小さいため、弱い操
作力でも作動することができる。In this case, the suction compression chamber 19 has a smaller cross-sectional area than the pressure accumulation chamber 20, and therefore the hydraulic pressure applied to the piston 10 when pushing down the piston rod 8 is small, so that it can be operated even with a weak operating force. I can do it.
一方、蓄圧室２０の横断面積は太きいため、吸引圧縮室
１９で圧縮された液状体はそのまま蓄圧室２０のピスト
ンＴに伝達され、流体力学的に拡大されるため、強力な
弾性を持つはね１３．１４でも、該ばねに抗してピスト
ン７は上昇することができる。On the other hand, since the cross-sectional area of the pressure accumulation chamber 20 is large, the liquid compressed in the suction compression chamber 19 is directly transmitted to the piston T of the pressure accumulation chamber 20 and expanded hydrodynamically, so it has strong elasticity. The springs 13, 14 also allow the piston 7 to rise against the springs.
特にピストン１０と７の横断面積の差が大きい程、それ
ぞれのピストン１０と１に掛る圧力差が大きくなること
は″パスカルの原理“から容易に想像できる。In particular, it can be easily imagined from "Pascal's principle" that the greater the difference in cross-sectional area between the pistons 10 and 7, the greater the pressure difference applied to the respective pistons 10 and 1.
また、ばね１４はピストン棒８を容易に上下操作動させ
るため、該ばね１４の弾性は比較的弱いものを使用し、
一方、ばね１３は蓄圧用として強力な弾性をもったもの
を使用することが望ましい。In addition, in order to easily move the piston rod 8 up and down, the spring 14 has relatively weak elasticity.
On the other hand, it is desirable to use a spring 13 with strong elasticity for pressure accumulation.
また、蓄圧力がそれ程要求されないものには、ばね１３
は省略してもよい。In addition, for those that do not require so much accumulated pressure, the spring 13
may be omitted.
蓄圧が進んでピストン７が通孔２１よりも上昇すると、
蓄圧室２０と通孔２１が連通して液状体は容器６内に流
出するため、ピストン７は蓄圧作動が続くにもかかわら
ず、通孔２１より上昇することはなく、従って蓄圧液状
体の定量化と定圧化を行なう。As the pressure builds up and the piston 7 rises above the through hole 21,
Since the pressure accumulating chamber 20 and the through hole 21 communicate with each other and the liquid flows out into the container 6, the piston 7 does not rise above the through hole 21 even though the pressure accumulating operation continues. and constant pressure.
蓄圧が完了すると操作筒１の握持を開放するもので、ピ
ストン棒８は上限位置に復帰した第４図の状態となる。When the pressure accumulation is completed, the grip on the operating cylinder 1 is released, and the piston rod 8 returns to the upper limit position, as shown in FIG. 4.

は噴霧される。In this state, the spray button 11 is pressed down, and as shown in FIG. Due to the communication, the liquid state under the accumulated pressure is sprayed.
噴霧が終了すると、第２図に示す状態に復帰し、次の蓄
圧及び噴霧に備えるものである。When the spraying is finished, the state returns to the state shown in FIG. 2 and prepares for the next pressure accumulation and spraying.
噴霧を行なっていくと、当然、容器６内の液状体は減量
し、その量だけ容器６内は減圧を生じる。As the spraying continues, the amount of liquid in the container 6 naturally decreases, and the pressure in the container 6 is reduced by that amount.
該減圧は液状体を吸引圧縮室１９内へ補充するのを困難
にするため、外部から空気の補充をする必要があるが、
本発明は、第３図に示されるようにピストン棒８が押下
げられると、キャップ２に貫通しているピストン棒８の
外周部の間隙２３が開口され、該間隙２３から通孔２１
を通じて容器６内に空気が補充できるようにしである。This reduced pressure makes it difficult to replenish the liquid into the suction compression chamber 19, so it is necessary to replenish air from the outside.
According to the present invention, when the piston rod 8 is pushed down as shown in FIG.
This allows air to be replenished into the container 6 through the opening.
本発明は以上のごときものであり、弱い蓄圧操作力でも
高圧化された蓄圧噴霧液が得られ、微細な霧とばねの伸
縮による圧力変動の少ない低コストの、しかも原液の再
充填可能な蓄圧噴霧装置が提供できるから、特に１回の

パターンと微細な霧が要求される家庭用、業務用の噴霧
、例えはへアースプレイ、殺虫剤、家庭用品、工業用品
、自動車用品、医薬品などの用途に効果がある。The present invention is as described above, and it is possible to obtain a highly pressurized spray liquid even with a weak pressure accumulating operation force, and it is a low-cost pressure accumulator that has little pressure fluctuation due to fine mist and spring expansion and contraction, and can be refilled with the undiluted solution. Because we can provide spraying equipment, we can especially use sprays for household and commercial purposes that require a stable spray pattern and fine mist, especially those that require a large amount of spray per time or a high frequency of use, such as hair spray, insecticides, etc. Effective for household goods, industrial goods, automobile goods, pharmaceuticals, etc.
