【考案の詳細な説明】 本案は正倒立両用の往復ポンプ式噴霧器で、手動でかつ
小型の噴霧器に係る。[Detailed description of the invention] The present invention relates to a reciprocating pump type sprayer that can be used both vertically and invertedly, and is manual and small.

この種噴霧器として、従来正立時にだけ使用できるもの
が広く知られているが、正立時だけの使用では不便であ
り、倒立時にも使用できることが望ましい。Conventionally, as this type of sprayer, one that can be used only when standing upright is widely known, but it is inconvenient to use only when standing upright, and it is desirable to be able to use it when standing upside down.

しかし正倒立両用の噴霧器にすると、その構造が複雑化
して高価となり易く、又弁の数も通常の往復ポンプ式噴
霧器の場合のように吸込み弁と吐出弁との二つのほか、
正立時の液体吸込み路からの空気吸込みを防止する弁、
又倒立時用液体吸込み路、更に正立時においてその倒立
時用液体吸込み路を閉塞する弁が必要となり、これ等の
構造を簡易化しようとすると吸込み液体との関係で弁が
正確に作動しない恐れも生ずる。However, if you use a sprayer that can be used both vertically and invertedly, the structure tends to be complicated and expensive, and the number of valves is different from the suction valve and discharge valve as in the case of a regular reciprocating pump type sprayer.
A valve that prevents air from being sucked in from the liquid suction path when standing upright.
In addition, a liquid suction path for when standing upside down and a valve that closes the liquid suction path for when standing upright are required, and if you try to simplify the structure of this, there is a risk that the valve will not operate correctly due to the relationship with the suction liquid. Also occurs.

本案は、それ等欠点を除去して構造が簡易でかつ弁が確
実に作動するよう設けたものであり、以下図面について
説明する。The present invention eliminates these drawbacks, provides a simple structure, and ensures reliable operation of the valve, and will be described below with reference to the drawings.

１は往復ポンプ式の噴霧器の一例を示す。1 shows an example of a reciprocating pump type sprayer.

ンダに対して下降して吐出弁１３を開きノズル孔９ａか
ら噴霧する。When the spray head 9 is pushed down against the bias, the sliding pipe 5 also descends, and at this time, the suction valve 11 normally provided on the inner surface of the lower end of the cylinder is in a closed state, so the pressure in the compression chamber 12 becomes high, and the piston Due to the difference in diameter, the sliding tube 5 descends relative to the large diameter cylinder, opens the discharge valve 13, and sprays from the nozzle hole 9a.

噴霧ヘッドが下降限に達すると、吐出弁が閉じ、続いて

げに備える。When the spray head reaches its lower limit, the discharge valve closes, and then when the spray head is released, the sliding pipe and the spray head rise, and the suction valve 11 opens due to the negative pressure in the compression chamber.
4 to suck in the liquid inside the container and prepare for the next depression of the spray head.

尚１５は圧縮室内を狭小化するための挿入部材で、該部
材は一部の蓄圧式噴霧器に使用されている。Reference numeral 15 denotes an insertion member for narrowing the inside of the compression chamber, and this member is used in some pressure accumulation type sprayers.

他種々の構造のものが知られており、本案はそのほとん
どに用いることが可能であるから、そのうちどのような
ものであっても差支えない。The illustrated example shows an example of a so-called pressure accumulator sprayer, but various other structures are known, and the present invention can be used for most of them, so any of them may be used. .

本案にあっては、下端が容器体の底部に達するよう設け
た吸込み管１４の下端に倒立時用空気吸込み防止弁２０
を設ける。In this case, an air suction prevention valve 20 for inversion is installed at the lower end of the suction pipe 14, which is provided so that the lower end reaches the bottom of the container body.
will be established.

該弁は図示のように、下部を弁室筒部２１としかつ上部
を仇吸込み管下端へ嵌合するための筒部２２とする弁室
形成部材２３を設けておき、その弁室筒内へ周壁２４外
面に突条２５を付設させた弁皿２６をその内部に玉野２
７を載置させて嵌合させればよい。As shown in the figure, the valve is provided with a valve chamber forming member 23 whose lower part is a valve chamber cylindrical part 21 and whose upper part is a cylindrical part 22 for fitting into the lower end of the suction pipe. A valve plate 26 with a protrusion 25 attached to the outer surface of the peripheral wall 24 is mounted inside the valve plate 26.
7 may be placed and fitted.

尚弁室筒部の上奥部に弁座２８を形成させておく。Note that a valve seat 28 is formed at the upper back of the valve chamber cylindrical portion.

２７が弁座２８に自重に抗して押付けられることはなく
、噴霧器倒立状態でだけ自重により玉野がその弁孔２９
を閉塞する。When sucking liquid with the sprayer in the upright state, the liquid is sucked through between the outer surface of the peripheral wall 24 of the valve plate, the protrusion 25, and the inner wall surface of the valve chamber cylinder, so that the sucked liquid causes the ball 27 to close to the valve seat. The valve hole 29 is not pressed against the valve hole 28 by its own weight only when the sprayer is in an inverted position.
occlude.

更に小径シリンダ３の胴部へは、倒立時用液体吸込み孔
３０を穿設させる。Furthermore, a liquid suction hole 30 for inversion is provided in the body of the small diameter cylinder 3.

該吸込み孔３０は、摺動管５が上限にある状態でだけ、
容器体内とポンプの圧縮室１２内とを連通可能とするも
ので、小径ピストン６が下降すると直ちにその連通は遮
断されるように設けておく。The suction hole 30 is opened only when the sliding pipe 5 is at the upper limit.
It allows communication between the inside of the container and the inside of the compression chamber 12 of the pump, and is provided so that the communication is immediately cut off when the small diameter piston 6 descends.

尚図示の噴霧器の場合は、小径シリンダに上記吸込み孔
３０を穿設させるが、異る構造の噴霧器の場合は、大径
シリンダに穿設する場合もある。In the case of the illustrated sprayer, the suction hole 30 is formed in the small-diameter cylinder, but in the case of a sprayer with a different structure, the suction hole 30 may be formed in the large-diameter cylinder.

第１図において、噴霧ヘッド９を押下げすると、摺動管
５が下降することで、上記の吸込み孔３０による圧縮室
内と容器体内との連通は遮断されるため、圧縮室は高圧
化され、よって通常の噴霧器と同様に操作できる。In FIG. 1, when the spray head 9 is pushed down, the sliding tube 5 descends, and the communication between the compression chamber and the container body through the suction hole 30 is cut off, so that the compression chamber is made to have a high pressure. Therefore, it can be operated in the same way as a normal sprayer.

噴霧器を倒立させたときは、容器体内液体に空気が上昇
するため、倒立時用空気吸込み弁２０は空気中に露出す
ることとなる。When the sprayer is inverted, air rises into the liquid inside the container, so the inverted air suction valve 20 is exposed to the air.

該状態から噴霧ヘッド９を押上げすると、倒立時用液体
吸込み孔３０は小径ピストン６の上昇によって直ちに圧
縮室１２から外れ、そのため圧縮室内の高圧化によって
正立時用吸込み弁１１の弁体１１ａは弁座１１ｂに押付
けられ、よって吐出弁１３が開き噴霧することが出る。When the spray head 9 is pushed up from this state, the inverted liquid suction hole 30 is immediately removed from the compression chamber 12 due to the rise of the small diameter piston 6, and as a result, the valve body 11a of the upright suction valve 11 is It is pressed against the valve seat 11b, so that the discharge valve 13 opens and sprays.

噴霧ヘッド９を離すと、吐出弁が閉じられたま）噴霧ヘ
ッドおよび摺動管がスプリング１６の付勢で下降し、玉
野２７が弁座２８に接することで倒立時用空気吸込み防
止弁２０が閉じ、圧縮室１２内は負圧化する。When the spray head 9 is released (while the discharge valve remains closed), the spray head and the sliding tube are lowered by the force of the spring 16, and the tamano 27 contacts the valve seat 28, which closes the air suction prevention valve 20 for inversion. , the pressure inside the compression chamber 12 becomes negative.

小径ピストン６が正立時における上限（倒立時における
下限）に達したとき、倒立時用液体吸込み孔３０が開く
ため容器体内液体が吸込みされ、次回の噴霧ヘッド押上
げに備える。When the small-diameter piston 6 reaches the upper limit in the upright position (lower limit in the inverted position), the inverted liquid suction hole 30 opens, and the liquid inside the container is sucked in to prepare for the next push-up of the spray head.

本案は上記構成とするもので倒立時用空気吸込み防止弁
２０は吸込み管下端に設けたから、これをシリンダ内に
設ける場合に比べてシリンダ内が複雑化することがなく
、かつ倒立時用液体吸込み孔３０があっても正立時用の
噴霧器として差支えないため、空気吸込み防止弁を吸込
み管下端に付設するだけで正立時用の往復ポンプ式噴霧
器を正倒立両用の噴霧器に出来ることとなって極めて便
利で、かつ正倒立両用であるに拘らず特にコスト高とな
ることはなく、又シリンダ胴部に倒立時用液体吸込み孔
３０を穿設させたから倒立時用液体吸込み管を設けなく
ともよいこととなる。In this case, the air suction prevention valve 20 for when inverted is provided at the lower end of the suction pipe, so the interior of the cylinder is not complicated compared to when it is installed inside the cylinder, and the air suction prevention valve 20 for when inverted is not Even with the holes 30, there is no problem with the sprayer being used when standing upright, so by simply attaching an air suction prevention valve to the lower end of the suction pipe, a reciprocating pump sprayer for standing upright can be made into a sprayer that can be used for both upright and inverted positions, which is extremely convenient. It is convenient and does not require high costs even though it can be used for both normal and inverted positions, and since the cylinder body is provided with a liquid suction hole 30 for inverted positions, there is no need to provide a liquid suction pipe for inverted positions. becomes.
