Description

【考案の詳細な説明】 本案は正倒立両用噴霧器に係る。[Detailed explanation of the idea] This case concerns a sprayer for both upright and inverted use.

従来、手動噴霧器は、液体を入れる容器と、該容器に装
置の液体送出用手動往復ポンプと、該ポンプに連設され
て該ポンプにより送出される容器中の液体を霧化噴出す
る噴霧ノズルとからなっている。Conventionally, a manual sprayer includes a container containing a liquid, a manual reciprocating pump for delivering the liquid to the container, and a spray nozzle connected to the pump to atomize and spray the liquid in the container to be delivered by the pump. It consists of

通常、上記ポンプは容器の口部に装着され、又ポンプは
下端に吸上げパイプを有し、このパイプの下端は容器の
底近くに至っている。Usually, the pump is mounted at the mouth of the container and has a suction pipe at its lower end, the lower end of which ends near the bottom of the container.

従って、この手動噴霧器を倒立した場合、吸上げパイプ
の下端が容器内空気中に出ることになり、該ポンプに特
別な備えがない限りポンプが容器中の空気を吸込んでし
１い噴霧作用が得られない。Therefore, when this manual sprayer is turned upside down, the lower end of the suction pipe will come out into the air inside the container, and unless the pump is specially equipped, the pump will not be able to suck in the air inside the container and will not be able to spray. I can't get it.

そこで、本案は効率よく噴霧作用が得られる正倒立両用
噴霧器を提供しようとするものである。Therefore, the present invention aims to provide a sprayer for both normal and inverted positions that can efficiently obtain a spraying action.

以下図示の実施例について説明する。The illustrated embodiment will be described below.

げている。The reciprocating pump 2 has a cylinder 6 inserted into the mouth of the container, and has two stages: a large diameter part 6a and a small diameter part 6b.
A flow path pipe 7 which also serves as a plunger and has a plunger is fitted so as to be vertically slidable, and the lower flow path opening of the flow path pipe 7 is used as a valve seat 8, and a rod-shaped valve body 9 is contacted and closed from below to form a discharge valve 10. A valve box 11 is arranged below the rod-shaped valve body 9, and the valve box has an outer diameter slightly smaller than the inner diameter of the small diameter part 6b of the cylinder 6, and is placed inside the large diameter part 6a of the cylinder. It is loosely inserted vertically, and its lower end is inserted into the upper part of the inside of the cylinder small diameter part 6b, and the valve box is provided with a taper valve seat 13 on the lower surface of the internal valve chamber 12 and a valve hole 32 that communicates with the inside of the cylinder small diameter part 6b. , valve chamber 1
A plurality of through holes 31 that open to the cylinder large diameter portion 6a are bored in the circumferential surface of the valve box at the upper part of the valve chamber 12, and a ball pusher 14 that seats on the valve seat 13 is movably inserted into the valve chamber 12. , a suction valve 15 that operates in an upright position, and a skirt-like part 16 is provided on the outer periphery of the flat end of the valve box 11, and the skirt-like part is slidably fitted into the cylinder small diameter part 6b. Thus, in the valve box 11, a suction valve flow path is formed from the cylinder small diameter part 6b to the cylinder large diameter part 6a via the valve hole 32, the valve seat 13, the valve chamber 12, the through hole 31... Further, a coil spring 17 is installed inside the cylinder small diameter portion 6b to spring the valve box 11 upward, thereby pushing up the flow path pipe 7 without closing the discharge valve 10.

プ１９を嵌着垂設させである。A spray head 4 having a spray nozzle 5 on the front surface is fitted into the flow path pipe 7, and a discharge valve 10,
A flow path leading to the spray nozzle 5 via the flow path pipe 7 is formed, and a suction pipe fitting part 18 is formed at the lower end of the cylinder small diameter part 6b, and a suction pipe extending in the housing near the bottom of the container 1 is connected to the suction pipe fitting part 18. The pipe 19 is fitted and installed vertically.

上記流路管７の抜出防止は、中央部で該流路管７を貫通
させたキャップ体２０にょシなさせ、該キャップ体２０
で往復ポンプ２を容器１０部に装着させである。In order to prevent the flow pipe 7 from being pulled out, the cap body 20 that penetrates the flow pipe 7 is inserted in the center.
Then, the reciprocating pump 2 is attached to 10 containers.

れる。In this sprayer, when the spray head 4 is pushed down by hand in an upright state, the liquid in the large diameter part 6a of the cylinder 60 is pressurized by the piston-shaped part 7a of the flow pipe 7 (at this time, the suction valve 1
5 is closed), and when the internal pressure becomes greater than the elasticity of the coil spring 1T, the valve body 11 moves further in advance against the coil spring 17 due to the difference in diameter between the large diameter part 6a and the small diameter part 6b of the cylinder, and is pushed down. , the discharge valve 10 opens, and the high-pressure liquid in the cylinder large-diameter portion 6a is atomized and jetted out from the spray nozzle 5 of the spray head 4 via the discharge valve 10 and the flow path pipe T.

そして、その噴出前コイルスプリング１７の弾力に相当
する分だけ蓄圧されるので液体は効率よく霧化される。Since the pressure corresponding to the elasticity of the pre-ejection coil spring 17 is accumulated, the liquid is efficiently atomized.

液体が吸上げられる。When the spray head 4 is stopped being pressed down, the discharge valve 10 is closed by the spring 17. Then, when the hand is released, the spring 17 pushes up the one casing flow path pipe 7 that is blocking the discharge valve 1o, and the cylinder is closed. The inside of the large diameter part 6a becomes negative pressure, the suction valve 15 opens, and the suction pipe 19 and the small diameter part 6 of the cylinder
b and the valve hole 32 of the suction valve 15, the valve seat 13, the valve chamber 12,
Liquid is sucked up into the cylinder large diameter portion 6a through the flow paths of the through holes 31.

尚、図中２１は容器１内の負圧化を防ぐ外気流通孔であ
り、外気はキャップ状体２０の流路管貫通孔及び外気流
通孔２１を通って容器内に入る。In the figure, reference numeral 21 denotes an outside air circulation hole for preventing negative pressure inside the container 1, and outside air enters the container through the flow pipe through hole of the cap-shaped body 20 and the outside air circulation hole 21.

ところで、上記構成の１までは、倒立状態に於いて往復
ポンプ２が容器１内の空気を吸込んでし１い、倒立状態
では使用できない。By the way, in the above configurations up to 1, the reciprocating pump 2 sucks the air inside the container 1 in the inverted state, and cannot be used in the inverted state.

ｂの筒体２８の位置に透孔３０を設けた。Therefore, the short tube 22 hanging down from the lower end of the large diameter portion 6a of the cylinder 60
An inner cylinder 24 having a downwardly tapered valve seat 23 is erected inside the lower end of the small diameter portion 6b of the cylinder, and a ball pusher 25 is loosely inserted into the inner cylinder 24, and a ball is pulled out from the inner surface of the lower part of the inner cylinder. An air suction valve 27 provided with blocking protrusions 26 is disposed, and a cylinder 28 is fitted to the outer periphery of the large-diameter portion 6a of the cylinder so that the upper end is open and liquid can flow, and the lower end of the cylinder 28 is connected to the small-diameter portion of the cylinder. 6b in a watertight manner, an upwardly directed skirt portion 29 is projected from the inner surface of the lower end of the cylinder body 28, and is brought into pressure contact with the inner periphery of the short hanging tube 22.
A through hole 30 was provided at the position of the cylinder 28 in b.

これによって、正立状態では、空気吸止弁２１は作用せ

内上部の空気が吸入されることなく、上述通りの噴霧作
用が得られる。As a result, in the upright state, the air intake valve 21 does not operate, and the skirt portion 29 of the cylinder body 28 presses against and closes the short hanging tube 22 of the cylinder. The above-mentioned atomizing effect can be obtained without inhaling air.

得られる。Next, in the inverted state, the air suction valve 28 is closed, and even if the suction pipe 19 protrudes into the air inside the container, the air will not be sucked into the reciprocating pump 2, and the air will not be sucked into the container mouth side. A certain liquid passes through the cylinder 28, opens the skirt 29, and is sucked into the reciprocating pump 2 through the through hole 30 of the cylinder small diameter part 6b, so that a spraying effect can be obtained without any trouble even in an inverted state.

本案によれば、往復ポンプ２に動作上のロスなく効率よ
い正世泣両用のものとなり、その構成は簡単である。According to the present invention, the reciprocating pump 2 has no operational loss and is efficient for both positive and negative purposes, and its configuration is simple.

又往復ポンプ２０周りに筒体２８を嵌めているので、容
器に対するポンプの漬脱に筒体２８が特に邪魔になるこ
となく、かつ損傷を生ずることもない。Furthermore, since the cylindrical body 28 is fitted around the reciprocating pump 20, the cylindrical body 28 does not get in the way of soaking and removing the pump from the container, and does not cause damage.
