Description

【0001】
【発明の属する技術分野】
本発明はトリガ−ハンドルの操作により水、洗剤、消毒液、殺虫剤、塗料等の各種液体を、連続噴霧できる小型、軽量な噴霧器に係り、詳しくは連続噴霧を止めたとき瞬時に停止し、ノズルから液が垂れることがない噴霧器に関するものである。
【0002】
【従来の技術】
従来のこの主の小型噴霧器としては、例えば主として殺虫剤を噴霧するエアゾ−ル型のもの(特開平1−176467号、特開平1−210057号)、薬液を噴霧するもの(実公昭55−4063号)、塗料等の噴霧させるもの(実公昭54−11282号)などが知られている。
これらはいずれも作動レバ−を操作したときだけ液が噴霧されるものであり、該作動レバーが元に戻ると液噴霧は止まり、液噴霧が間欠的にしか行なわれない。
【0003】
そこで、小型で連続噴霧できる噴霧器として、図8や図9のものが知られている。
図8は主として農業用に使用されるもので、シリンダS内をピストンPが往復し、空気をタンクTの空間K内で畜圧させ、この圧力で液を噴霧するものである。また噴霧を止めたいときはコックCを閉めることにより行うが、空間K内はまだ圧力があるので液だれが生じても農地で使用するものであるからあまり問題にはならない。
また図9のものは予めシリンダS内にピストンPを往復させ空間Kを畜圧しノズルNを押すと噴霧する構造である。また指をノズルNから外せば噴霧は瞬間に停止して液だけは生じないが、空気がすぐなくなるので作動時間が短い欠点がある。
【0004】
更に、トリガ−ハンドルを操作して、タンクからノズルまでの通液管の途中に液をバネ材に抗して一時的に蓄え、その液が所定以上に達したとき空気圧とバネ材の反発力で液をノズルへ送る蓄圧室を備えた噴霧器が知られている。
この蓄圧室型の噴霧器は、連続噴霧が可能で、且つガスを使用していないので安価であるが、トリガ−ハンドルの操作を止めたとき蓄圧室内に残った液がノズルへ送られ、しかも圧力が低下しているのでノズルから液がたれるので、室内では使用できなかった。
【0005】
【発明が解決しようとする課題】
そこで本出願人は先に噴霧器本体と、タンクと、噴霧器本体に取付けたトリガ−ハンドルと、そのトリガ−ハンドルの操作により開閉する弁で前記タンクから吸入して液を一時的に溜める液溜部と、該液溜部から給送されて液を噴霧するノズルとからなる噴霧器において、前記液溜部とタンクとの間に液戻し管を設け、その液戻し管に液溜部の内圧を瞬時にゼロにする圧力逃がし機構を設けたことを特徴とする噴霧器の液垂れ防止装置を提案した(特開平5−104041号)。
ところが、この機構では製造が大変で高価になるおそれがあった。
【0006】
そこで更に本出願人は、トリガ−ハンドルの操作を止めたとき、前記通液管にノズルへ送る液の流れを完全に塞ぐ遮断機構と、前記畜圧室内の圧力を瞬時に減圧する減圧機構とが同時に作用するようにした噴霧器を発明した(特願平8−31315号)。
この発明により安価に製造できて、ハンドルの操作を止めて連続噴霧を中止した瞬間にノズルから液が垂れることがない噴霧器を提供できた。
本発明は更に上記の特許を改良し、より構造を簡単にして部品数を少なくし、安価にした液だれのない小型の連続噴霧器を得ることを目的とする。
【0007】
【課題を解決するための手段】
本発明に係る噴霧器は、噴霧器本体と、タンクと、トリガ−ハンドルと、そのトリガ−ハンドルの操作に連動して弁を開閉させることにより前記タンクから第1通液管を介して液を吸入しバネ材に抗してその液を一時的に蓄える蓄圧室と、その蓄圧室内の液が所定以上に達したとき前記バネ材の反発力と圧縮空気圧とにより蓄圧室内の液を第2通液管を介してノズルへ送る噴霧器において、
第2通液管の途中に前記タンクに液を戻す第3通液管をバルブ体を介して設け、該バルブ体にはノズルへ液を送付するときは第3通液管への送付を遮断し、第3通液管へ液を送付するときはノズルへの液の送付を遮断する制御機能を設けたものである。
【0008】
またこのバルブ体の制御機能は、例えばバルブ体にシ−ソ−ボタンを設け、該シ−ソ−ボタンは常にバブル体のノズルへ液を送付する部分または第3通液管へ液を送付する部分のどちらか一方を押しつぶして変形させることにより液の流れを完全に防止するようにしたものである。
【0009】
【発明の実施の形態】
以下、本発明の一実施例を図面に基づいて説明する。
図1は本発明の噴霧器1の正面図で、この図において、符号2は噴霧器本体であり、水、洗剤等の各種液体3を蓄えたタンク4の上に載置されている。
この噴霧器本体2にはトリガ−ハンドル5が回動軸6によって回動自在に取付けられていて、該トリガ−ハンドル5の操作により連動して吸い込み弁7・吐き出し弁8が開閉し、第1通液管9を介して前記タンク4から液3を吸引し、該液を一時的に蓄える蓄圧室10へ送っている(図2参照)。
【0010】
この蓄圧室10には蓄圧室を構成する壁面11が設けられ、その壁面11は常に蓄圧室10の容積を減少させる方向に付勢されるバネ材12により支持されている。
そしてトリガ−ハンドル5の操作を何度も繰り返すことにより蓄圧室10内に液3が所定量以上溜まると、このバネ材12と圧縮空気の反発力で蓄圧室10内の液は蓄圧室10からノズルまでの第2通液管13を介して図3に示すようにノズル14に給送され噴霧されるものである。
【0011】
また前記トリガ−ハンドル5には、噴霧器本体1のピストン15の端部が当接し、このピストン15は常時バネ材16によってトリガ−ハンドル5を噴霧器本体2から引離す方向に付勢されている。
【0012】
第2通液管13の途中には、前記タンク4に液3を戻す第3通液管17がバルブ体18を介して設けられている。
このバブル体18は、液3をノズル14へ送付するときは第3通液管17への送付を遮断し、第3通液管17へ液3を送付するときはノズル14への液の送付を遮断する制御機能を設けている。
このバルブ体18の制御機能としては、弁で塞ぐ、プレ−トを移動させて管内を塞ぐ、管自体を窄める等通液管内の液を開閉する構造であればその種類を問わないが、図の場合はバルブ体18の上部にシ−ソ−ボタン19を設け、該シ−ソ−ボタン19の一対の突起部19a・19bが常にバブル体18のノズル14へ液3を送付する部分18aまたは第3通液管17へ液3を送付する部分18bのどちらか一方を押圧変形させて液の流れを完全に防止するようにしている。
【0013】
図4・図5はその説明図で、シ−ソ−ボタン19はバネ材20を介して軸21を支点に揺動し、シ−ソ−ボタン19の下面に設けた一対の突起部19a・19bが常にバブル体18のノズル14へ液3を送付する部分18aまたは第3通液管17へ液3を送付する部分18bのどちらか一方を押圧して変形させ、その変形させた側には液3が流れないように構成されている。
即ち、図4の場合は、突起部19bが第3通液管17へ液3を送付するバブル体18の部分18bを押圧して閉とする一方、突起部19aがノズル14へ液3を送付するバブル体18の部分18aを開とするので蓄圧室10から第2通液管13を介してノズル14へ液3が送られる。
【0014】
また軸21を支点にシ−ソ−ボタン19を揺動させて図5のように突起部19aがノズル14へ液3を送付する部分18aを押しつぶして閉とすると、突起部19bは第3通液管17へ液3を送付する部分18bが開となって液3がタンク4に戻るものである。
図6は前記第1通液管9、蓄圧室10、第2通液管13、第3通液管17の位置関係を示す端面図である。
【0015】
次に上記実施例の動作について説明する。
トリガ−ハンドル5を軸6を支点に回動させると、バネ16に抗してピストン15が押込まれる。
次いで、トリガ−ハンドル5の操作力を解除すると、ピストン15がバネ16で押出される。このため、噴霧器本体2内の第1通液管9内は負圧となり、吸い込み弁7を開いてタンク4内の液3を吸い出す。
【0016】
そして、再びトリガ−ハンドル5を回動させてピストン15を押込むと、液3は吐き出し弁9を開いて蓄圧室10内へ送られる。
このトリガ−ハンドル5の操作を数回繰返し行い、蓄圧室10内へ導入される液3が多くなるにつれて、壁面11がバネ材12に抗して移動し、ついにはその蓄圧室10の圧力がノズル14の弁22のバネ23に抗して該弁22を押し開く以上に達したとき該ノズル14から液3が噴射される。
以後、トリガ−ハンドル5を連続的に操作することにより、1回のハンドル5の操作で引出される液量3がノズル14から噴霧される量よりも多くしておけば、トリガ−ハンドル5を元に戻したとき(バネ16により戻るので短時間で戻る)も蓄圧室10の空気圧が所定以下(ノズル14の弁22が閉じる圧力)になるまでは、ノズル14からの液噴霧が連続して行われる。
【0017】
そして、トリガ−ハンドル5の操作を止めるときは、トリガ−ハンドル5の操作を止めると同時に図7のように前記シ−ソ−ボタン19の突起部19aに対応する上面を押すと、該突起部19aがノズル14へ液3を送付する部分18aを押しつぶして変形させ、液の流れを完全に塞ぎ、ノズル14への液3の供給が止まる。
また同時に突起部19bは第3通液管17へ液3を送付する部分18bから開放されて開となりタンク4と連通されるため蓄圧室10内が減圧されて内圧が瞬時にゼロになるので、単にノズル14からの噴霧が停止するだけではなく、液垂れが防止できる。
そして、第2通液管13内に残った液3は第3通液管17へ介してタンク4を戻るので無駄がない。
【0018】
【発明の効果】
以上のように、畜圧室を備えた噴霧器において、トリガ−ハンドルの操作を止めて連続噴霧を停止させたとき、液をノズルへ送る部分、またはタンクへ戻す部分のどちらか一方を常に開閉させる制御機能を有するバルブ体を設けたので、そのバブル体を操作するだけで、連続噴霧だけではなく、噴霧を止めたときも単に液のノズルへの供給を停止させるだけではなく、蓄圧室とタンクに連通させることにより蓄圧室の内圧を瞬時にゼロにさせることにより、蓄圧室内に残った液がノズルへ送られノズルから液がたれることを防止できる。
またこのバブル体の制御機能をバルブ体にシ−ソ−ボタンを設け、該シ−ソ−ボタンを常にバブル体のノズルへ液を送付する部分または第3通液管へ液を送付する部分のどちらか一方を押圧変形させて液の流れを完全に防止するようにすれば、操作が簡単で、しかも従来品に比べ構造がより簡単になり部品が少なくてすみ、より安価に製造できる利点がある。

BACKGROUND OF THE INVENTION
The present invention relates to a small, lightweight sprayer capable of continuously spraying various liquids such as water, detergent, disinfectant, insecticide, paint, etc. by operating a trigger handle. Specifically, when the continuous spraying is stopped, it stops instantaneously. The present invention relates to a sprayer in which liquid does not drip from a nozzle.
[0002]
[Prior art]
As this conventional small sprayer, for example, an aerosol type spraying mainly an insecticide (JP-A-1-176467, JP-A-1-210057), or spraying a chemical solution (Japanese Utility Model Publication No. 55-4063). No.), and spraying materials such as paint (Japanese Utility Model Publication No. 54-11282) are known.
In either case, the liquid is sprayed only when the operation lever is operated. When the operation lever returns to the original position, the liquid spray stops and the liquid spray is performed only intermittently.
[0003]
Then, the thing of FIG. 8 and FIG. 9 is known as a small-sized sprayer which can be sprayed continuously.
FIG. 8 is mainly used for agriculture, in which the piston P reciprocates in the cylinder S, the air is stored in the space K of the tank T, and the liquid is sprayed at this pressure. Further, when it is desired to stop the spraying, it is performed by closing the cock C. However, since there is still pressure in the space K, even if dripping occurs, it is used in farmland, so it does not cause much problem.
9 has a structure in which the piston P is reciprocated in the cylinder S in advance to spray the space K and press the nozzle N. Also, if the finger is removed from the nozzle N, spraying stops instantaneously and no liquid is produced, but there is a disadvantage that the operation time is short because the air is immediately lost.
[0004]
Furthermore, by operating the trigger handle, the liquid is temporarily stored against the spring material in the middle of the flow pipe from the tank to the nozzle, and when the liquid reaches a predetermined level or more, the air pressure and the repulsive force of the spring material A nebulizer having a pressure accumulating chamber for sending liquid to a nozzle is known.
This pressure accumulator type nebulizer is inexpensive because continuous spraying is possible and gas is not used, but when the operation of the trigger-handle is stopped, the liquid remaining in the pressure accumulator chamber is sent to the nozzle and the pressure is increased. Since the liquid dropped from the nozzle, it could not be used indoors.
[0005]
[Problems to be solved by the invention]
Therefore, the applicant of the present invention firstly has a sprayer main body, a tank, a trigger handle attached to the sprayer main body, and a liquid storage part for temporarily storing the liquid sucked from the tank by a valve that opens and closes by operation of the trigger handle. And a nozzle for spraying the liquid fed from the liquid reservoir, a liquid return pipe is provided between the liquid reservoir and the tank, and the internal pressure of the liquid reservoir is instantaneously applied to the liquid return pipe. A device for preventing dripping of a sprayer, which is provided with a pressure relief mechanism for reducing the pressure to zero is proposed (Japanese Patent Laid-Open No. 5-104041).
However, this mechanism is difficult to manufacture and may be expensive.
[0006]
Therefore, the present applicant further provides a shut-off mechanism that completely blocks the flow of liquid sent to the nozzle through the liquid passage when the operation of the trigger handle is stopped, and a pressure reducing mechanism that instantaneously reduces the pressure in the animal pressure chamber. Have invented a sprayer that can be operated simultaneously (Japanese Patent Application No. 8-31315).
According to the present invention, it is possible to provide a sprayer that can be manufactured at a low cost and does not drip from the nozzle at the moment when the operation of the handle is stopped and the continuous spraying is stopped.
Another object of the present invention is to improve the above-mentioned patent, and to obtain a small continuous sprayer free from dripping which has a simpler structure, a smaller number of parts, and a lower cost.
[0007]
[Means for Solving the Problems]
The sprayer according to the present invention sucks liquid from the tank through the first fluid pipe by opening and closing the valve in conjunction with the operation of the sprayer body, the tank, the trigger handle, and the trigger handle. A pressure accumulating chamber that temporarily stores the liquid against the spring material, and when the liquid in the pressure accumulating chamber reaches a predetermined level or more, the repulsive force of the spring material and the compressed air pressure cause the liquid in the pressure accumulating chamber to flow through the second fluid passage pipe. In the sprayer that sends to the nozzle through
A third liquid pipe for returning the liquid to the tank is provided in the middle of the second liquid pipe via a valve body, and when the liquid is sent to the nozzle, the delivery to the third liquid pipe is blocked. When the liquid is sent to the third liquid passing pipe, a control function is provided to block the sending of the liquid to the nozzle.
[0008]
In addition, for example, a seesaw button is provided on the valve body, and the seesaw button always sends the liquid to the bubble body nozzle or to the third liquid pipe. One of the portions is crushed and deformed to completely prevent the liquid flow.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a front view of a sprayer 1 of the present invention. In this figure, reference numeral 2 denotes a sprayer body, which is placed on a tank 4 that stores various liquids 3 such as water and detergent.
A trigger handle 5 is rotatably attached to the sprayer main body 2 by a rotating shaft 6, and the suction valve 7 and the discharge valve 8 are opened and closed in conjunction with the operation of the trigger handle 5. The liquid 3 is sucked from the tank 4 through the liquid pipe 9 and sent to the pressure accumulating chamber 10 for temporarily storing the liquid (see FIG. 2).
[0010]
The pressure accumulating chamber 10 is provided with a wall surface 11 constituting the pressure accumulating chamber, and the wall surface 11 is supported by a spring material 12 that is always urged in a direction to reduce the volume of the pressure accumulating chamber 10.
When the operation of the trigger handle 5 is repeated many times and the liquid 3 is accumulated in the accumulator 10 by a predetermined amount or more, the liquid in the accumulator 10 is discharged from the accumulator 10 by the repulsive force of the spring material 12 and the compressed air. As shown in FIG. 3, it is fed and sprayed to the nozzle 14 through the second liquid passage 13 to the nozzle.
[0011]
Further, the end of the piston 15 of the sprayer body 1 abuts against the trigger handle 5, and this piston 15 is constantly urged by a spring material 16 in a direction to separate the trigger handle 5 from the sprayer body 2.
[0012]
A third liquid pipe 17 for returning the liquid 3 to the tank 4 is provided in the middle of the second liquid pipe 13 via a valve body 18.
When the liquid 3 is sent to the nozzle 14, the bubble body 18 blocks the delivery to the third liquid pipe 17, and when the liquid 3 is sent to the third liquid pipe 17, the liquid is sent to the nozzle 14. A control function is provided to shut off.
The control function of the valve body 18 may be of any type as long as it is a structure that opens and closes the liquid in the liquid passing pipe, such as closing the valve, closing the pipe by moving the plate, and closing the pipe itself. In the case of the figure, a seesaw button 19 is provided on the top of the valve body 18, and the pair of projections 19a and 19b of the seesaw button 19 always sends the liquid 3 to the nozzle 14 of the bubble body 18. Either one of 18a or the part 18b for sending the liquid 3 to the third liquid pipe 17 is pressed and deformed to completely prevent the liquid flow.
[0013]
FIGS. 4 and 5 are explanatory diagrams, and the seesaw button 19 swings around a shaft 21 via a spring material 20 as a fulcrum, and a pair of protrusions 19a. 19b always presses and deforms either the part 18a for sending the liquid 3 to the nozzle 14 of the bubble body 18 or the part 18b for sending the liquid 3 to the third liquid pipe 17, and on the deformed side, The liquid 3 is configured not to flow.
That is, in the case of FIG. 4, the protruding portion 19 b presses and closes the portion 18 b of the bubble body 18 that sends the liquid 3 to the third liquid passing pipe 17, while the protruding portion 19 a sends the liquid 3 to the nozzle 14. Since the part 18 a of the bubble body 18 to be opened is opened, the liquid 3 is sent from the pressure accumulating chamber 10 to the nozzle 14 through the second liquid passage 13.
[0014]
When the seesaw button 19 is swung with the shaft 21 as a fulcrum and the projection 19a crushes and closes the portion 18a for sending the liquid 3 to the nozzle 14 as shown in FIG. The portion 18 b for sending the liquid 3 to the liquid pipe 17 is opened, and the liquid 3 returns to the tank 4.
FIG. 6 is an end view showing the positional relationship among the first liquid pipe 9, the pressure accumulation chamber 10, the second liquid pipe 13, and the third liquid pipe 17.
[0015]
Next, the operation of the above embodiment will be described.
When the trigger handle 5 is rotated about the shaft 6 as a fulcrum, the piston 15 is pushed against the spring 16.
Next, when the operating force of the trigger handle 5 is released, the piston 15 is pushed out by the spring 16. For this reason, the inside of the first liquid passage 9 in the sprayer main body 2 becomes negative pressure, and the suction valve 7 is opened to suck out the liquid 3 in the tank 4.
[0016]
Then, when the trigger handle 5 is rotated again and the piston 15 is pushed in, the liquid 3 opens the discharge valve 9 and is sent into the pressure accumulation chamber 10.
The operation of the trigger-handle 5 is repeated several times. As the liquid 3 introduced into the pressure accumulating chamber 10 increases, the wall surface 11 moves against the spring material 12, and finally the pressure in the pressure accumulating chamber 10 is increased. The liquid 3 is ejected from the nozzle 14 when the valve 22 is pushed and opened more than the spring 23 of the valve 22 of the nozzle 14.
Thereafter, by continuously operating the trigger handle 5, if the amount of liquid 3 drawn out by one operation of the handle 5 is made larger than the amount sprayed from the nozzle 14, the trigger handle 5 is moved. Even when the pressure is restored (returned by the spring 16 so that it returns in a short time), the liquid spray from the nozzle 14 continues until the air pressure in the pressure accumulating chamber 10 becomes equal to or lower than a predetermined pressure (pressure to close the valve 22 of the nozzle 14) Done.
[0017]
When the operation of the trigger handle 5 is stopped, the operation of the trigger handle 5 is stopped and simultaneously the upper surface corresponding to the protrusion 19a of the seesaw button 19 is pushed as shown in FIG. 19a crushes and deforms the portion 18a that sends the liquid 3 to the nozzle 14, completely blocks the flow of the liquid, and the supply of the liquid 3 to the nozzle 14 stops.
At the same time, the protrusion 19b is opened from the portion 18b for sending the liquid 3 to the third liquid pipe 17 and is opened and communicated with the tank 4, so that the pressure in the pressure accumulating chamber 10 is reduced and the internal pressure instantaneously becomes zero. Not only spraying from the nozzle 14 is stopped, but also dripping can be prevented.
Then, the liquid 3 remaining in the second liquid pipe 13 returns to the tank 4 through the third liquid pipe 17, so there is no waste.
[0018]
【The invention's effect】
As described above, in a sprayer equipped with a stock pressure chamber, when the operation of the trigger handle is stopped and the continuous spraying is stopped, either the part for sending liquid to the nozzle or the part for returning to the tank is always opened and closed. Since the valve body with control function is provided, not only the continuous spraying but also the supply of liquid to the nozzle is stopped when the spraying is stopped by operating the bubble body. By making the internal pressure of the pressure accumulator chamber zero instantaneously by communicating with the liquid, it is possible to prevent liquid remaining in the pressure accumulator chamber from being sent to the nozzle and dripping from the nozzle.
In addition, a control button for the bubble body is provided with a seesaw button on the valve body, and the seesaw button is used to send the liquid to the nozzle of the bubble body or to send the liquid to the third liquid pipe. If one of them is pressed and deformed to completely prevent the flow of liquid, the operation is simpler, the structure is simpler and the number of parts is less than that of the conventional product, and the advantage is that it can be manufactured at a lower cost. is there.
