Description

【０００１】
【発明の属する技術分野】
本発明は、送風機を用いて揮散性薬剤を気中に放出する送風式薬剤放散装置に関し、さらに詳しくは、一度使用した後に使用を中止した休止時に揮散性薬剤が自然に気中に放出することを防止できる送風式薬剤放散装置に関する。
【０００２】
【従来の技術】
特許文献１に、吸い込み口と吐き出し口を有する装置本体と、この装置本体内に設けた送風機と、揮散性薬剤を備え、送風機を駆動することで揮散性薬剤に送風して揮散性薬剤を吐き出し口から気中に放出する送風式薬剤放散装置が開示されている。
【０００３】
特許文献２に、装置本体の空気吸入窓、空気排出窓に蓋を、それぞれ開閉自在に設けた送風式の薬剤放散装置が開示されている。

【発明が解決しようとする課題】
特許文献１に開示された送風式薬剤放散装置は、揮散性薬剤を装置本体にセットし、送風機を駆動して使用している際に、送風機を停止して使用を中止した休止時には揮散性薬剤が吸い込み口、吐き出し口から気中に連通するので、揮散性薬剤が自然に気中に放出されることを防止できない。
このために、休止期間中に揮散性薬剤が順次気中に放出されて減少し、無駄である。
【０００６】
前述のことを解消するには、特許文献２に開示されたように、装置本体の吸い込み口と吐き出し口に蓋を設け、使用時には蓋を開放して空気が装置本体内に流通する使用状態とし、休止時には蓋を閉塞して空気が装置本体内に流通しない休止状態とすることが考えられる。
【０００７】
しかし、前述のようにすると、蓋を設けなければならず、部品点数が多くコストが高くなる。
また、吸い込み口と吐出き口に設けた２つの蓋を開閉操作して使用状態と休止状態とするので、その操作が面倒である。
【０００８】
本発明は、前述の課題に鑑みなされたものであって、その目的は、休止期間中に揮散性薬剤が気中に自然に放出されることを防止できると共に、コストが安く、簡単な操作で使用状態、休止状態にできる送風式薬剤放散装置を提供することである。
【０００９】
【課題を解決するための手段】
第１の発明は、容器支持部５を有する装置本体１と、この装置本体１に設けた送風機２と、前記容器支持部５に支持される薬剤収納容器３と、この薬剤収納容器３内に収納した揮散性薬剤４を備え、
前記容器支持部５は、前記送風機２を駆動することで空気が流通する開口部１７を有した他側面５ｂと、この他側面５ｂと間隔を置いて対向した一側面５ａを有し、
前記薬剤収納容器３は、前記容器支持部５の一側面５ａに接すると共に、第１通気部６を有した表面３ａと、前記容器支持部５の他側面５ｂに接すると共に、第２通気部７を有した裏面３ｂを有し、この薬剤収納容器３は前記容器支持部５に、第１位置と第２位置で支持され、
前記薬剤収納容器３を第１位置で支持した場合には、第１通気部６が大気に開口し、かつ第２通気部７が前記開口部１７に連通し、
前記薬剤収納容器３を第２位置で支持した場合には、第１通気部６が容器支持部５の一側面５ａで閉塞され、かつ第２通気部７が容器支持部５の他側面５ｂで閉塞されるようにしたことを特徴とする送風式薬剤放散装置である。
【００１０】
第２の発明は、第１の発明において第１通気部６の開口面積は表面３ａの面積のほぼ半分で、第２通気部７の開口面積は裏面３ｂの面積のほぼ半分である送風式薬剤放散装置である。
【００１１】
第３の発明は、第１又は第２の発明において容器支持部５に薬剤収納容器３が第１位置と第２位置に回転可能に支持されている送風式薬剤放散装置である。
【００１２】
第４の発明は、第３の発明において容器支持部５の一側面５ａ、他側面５ｂは薬剤収納容器３の表面３ａ、裏面３ｂよりも大きく、
前記一側面５ａ、他側面５ｂには第１開口４１、第２開口４２が周方向に間隔を置いてそれぞれ複数形成され、
前記薬剤収納容器３の表面３ａ、裏面３ｂには、第３開口４３、第４開口４４が周方向に間隔を置いてそれぞれ複数形成され、その複数の第３開口４３で第１通気部６を形成し、複数の第４開口４４で第２通気部７を形成し、
送風機２を駆動することで第１開口４１と第２開口４２に空気が流通し、
前記薬剤収納容器３が第１位置の時には、第１開口４１と第３開口４３、第２開口４２と第２開口４４がそれぞれ連通し、
前記薬剤収納容器３が第２位置の時には、第３開口４３、第４開口４４が容器支持部５でそれぞれ閉塞される送風式薬剤放散装置である。
【００１３】
第５の発明は、第１又は第２の発明において、容器支持部５に薬剤収納容器３が第１位置と第２位置にスライド可能に支持されている送風式薬剤放散装置である。
【００１４】
【作用】
第１の発明によれば、薬剤収納容器３を第１位置で支持することで、第１通気部６が大気に開口し、かつ第２通気部７が開口部１７に連通するので、送風機２を駆動することで、開口部１７、第２通気部７、薬剤収納容器３内部、第１通気部６に空気が流通するから、揮散性薬剤４を気中に放散できる。
また、薬剤収納容器３を第２位置で支持すると、その第１通気部６が容器支持部５の一側面５ａで閉塞され、第２通気部７が他側面５ｂで閉塞されるので、休止期間中に揮散性薬剤４が気中に自然に放出されることを防止できる。
【００１５】
また、薬剤収納容器３を第１位置と第２位置に支持すれば良く、他の部材を設ける必要がないから、コストの安い送風式薬剤放散装置であると共に、簡単な操作で使用状態、休止状態にできる。
【００１６】
第２の発明によれば、薬剤収納容器３の第１通気部６、第２通気部７の開口面積が大きく、その薬剤収納容器３内部にスムーズに空気が流通するから、揮散性薬剤４を気中にスムーズに放散できる。
【００１７】
第３の発明によれば、薬剤収納容器３を容器支持部５に支持したままで、第１位置と第２位置に回転できるから、その操作が容易で、使用状態、休止状態とする操作がより簡単である。
【００１８】
第４の発明によれば、薬剤収納容器３を第１位置と第２位置に回転する角度が小さく、薬剤収納容器３を素早く第１位置、第２位置に回転することができる。
【００１９】
第５の発明によれば、薬剤収納容器３を容器支持部５に支持したままで、第１位置と第２位置にスライドできるから、その操作が容易で、使用状態、休止状態とする操作がより簡単である。
【００２０】
【発明の実施の形態】
図１に示すように、装置本体１と、この装置本体１に設けた送風機２と、薬剤収納容器３と、この薬剤収納容器３内に収納した揮散性薬剤４で送風式薬剤放散装置を構成している。
前記装置本体１は容器支持部５を有する。
【００２１】
前記薬剤収納容器３は、前記容器支持部５に周方向に回転して第１位置と第２位置に支持可能で、その表面３ａに第１通気部６が形成され、裏面３ｂに第２通気部７が形成してある。
前記送風機２はファン２ａとモータ２ｂを備え、そのモータ２ｂでファン２ａを駆動することで容器支持部５に空気が流通するようにしてある。
【００２２】
図１に示すように、薬剤収納容器３を第１位置で支持した状態で、送風機２を駆動すると第１通気部６と第２通気部７とに空気が流通し、使用状態となる。
図２に示すように、薬剤収納容器３を第２位置で支持すると、第１・第２通気部６，７が閉塞されて休止状態となる。
【００２３】
このようであるから、薬剤収納容器３を第１位置で支持し、送風機２を駆動することで、薬剤収納容器３内に空気が流通して揮散性薬剤４を気中に放出できる。
また、薬剤収納容器３を第２位置で支持することで、薬剤収納容器３内部が気中と遮断され、その内部に収納した揮散性薬剤４が自然に気中に放出されることを防止できる。
【００２４】
次に、各部の具体形状の一例を説明するが、これに限ることはない。
前記装置本体１は図１と図３に示すように、一側縦壁１０と他側縦壁１１と中間縦壁１２と一端縦壁１３と他端縦壁１４と上壁１５と下壁１６で中空部１ａと上向き凹部１ｂを有する箱形状で、その上向き凹部１ｂを容器支持部５としている。つまり、容器支持部５は、対向した一側面５ａ、他側面５ｂと周面５ｃで上面が開口した箱形状で、他側面５ｂが一側面５ａよりも上方に突出している。
前記中間縦壁１２の下部寄りに第１開口部１７を形成し、この第１開口部１７で中空部１ａと上向き凹部１ｂを連通すると共に、上壁１５に第２開口部１８を形成し、前記中空部１ａに送風機２を設け、送風機２を駆動することで容器支持部５に空気が流通するようにしてある。
【００２５】
前記薬剤収納容器３は図４（ａ），（ｂ）に示すように、表面板２０と裏面板２１と周面板２２で断面円形の中空形状で、図１に示すように、その中空部に揮散性薬剤４が収納してある。
前記表面板２０（前記表面３ａ）に第１通気部６が形成され、前記裏面板２１（前記裏面３ｂ）に第２通気部７が形成してある。
【００２６】
前記第１通気部６と第２通気部７は上下方向に位置がずれている。例えば、第１通気部６が上方位置に形成され、第２通気部７が下方位置に形成してある。
そして、薬剤収納容器３を図１に示すように第１位置で支持すると第１通気部６が一側縦壁１０（一側面５ａ）よりも上方に突出して大気に連通し、第１開口部１７と第２通気部７が連通する。
前記薬剤収納容器３を周方向に回転、例えば１８０度回転して図２に示すように第２位置で支持すると、第１通気部６が下方位置となり、一側縦壁１０（一側面５ａ）で閉塞され、第２通気部７が上方位置となり、中間縦壁１２（他側面５ｂ）の上部寄りで閉塞される。
【００２７】
この実施の形態では、図３に示すように装置本体１の上壁１５がほぼ半円形状で他側縦板１１、中間縦板１２の上部寄りはほぼ半円形状であり、第１開口部１７はほぼ半円形の下開口縁１７ａと直線状の上開口縁１７ｂでほぼ下向きの半円形状である。
また、薬剤収納容器３の表面板２０、裏面板２１は円板状で、周面板２２は円筒形状である。その表面板２０のほぼ上半分に、第１通気部６がほぼ上向き半円形状で、前記裏面板２１のほぼ下半分に、第２通気部７がほぼ下向き半円形状、つまり前述の第１開口部１７の外周形状と同一形状に形成してある。
【００２８】
このようであるから、第１通気部６、第２通気部７の開口面積が表面板２０、裏面板２１（表面３ａ、裏面３ｂ）の面積のほぼ半分で、空気をスムーズに流通することができる。
この実施の形態では、第１・第２通気部６，７をほぼ半円形スリット状の穴６ａ，７ａを同心状に複数形成してある。
これは、揮散性薬剤４を粒状、好ましくは球状の薬剤含浸体４ａに含浸させ、その薬剤含浸体４ａを直接薬剤収納体３内部に収納したので、その薬剤含浸体４ａがこぼれ落ちないようにするためであって、前述の薬剤含浸体４ａを網袋などの通気性袋に入れて収納した場合には第１・第２通気部６，７を連続した半円形状とすることができる。前述の粒状の薬剤含浸体４ａの他に、貫通孔を有するハニカム状、格子状など構造体を薬剤含浸体として用いることができる。
【００２９】
図３に示すように、前記装置本体１の容器支持部５の両端開口縁（周面５ｃの両端部）、つまり一端縦壁１３、他端縦壁１４の上端面に凹部１９がそれぞれ形成してある。
図４に示すように、前記薬剤収納容器３の周面板２２に一対の支持片２３が設けてある。
この一対の支持片２３が各凹部１９に嵌め込みされることで、薬剤収納容器３を第１位置、第２位置で安定して支持することができるようにしてある。
【００３０】
図５に示すように、薬剤収納容器３の表面板２０の上下中央部に横片２４を径方向に向けて設け、この横片２４を一側縦板１０の上端面１０ａ（一側面５ａの上端部）に接して第１位置、第２位置で安定して支持するようにしても良い。
【００３１】
この実施の形態では、装置本体１の底壁１６は二重壁形状で、電池収納室１ｃを形成している。
この電池収納室１ｃに電池８が収納され、その電池８で送風機２のモータ２ｂを駆動してファン２ａを回転するようにしてある。
また、送風機２のファン２ａはシロッコファンであり、第１開口部１７を吸い込み口、第２開口部１８を吐き出し口としてあるが、ファン２ａをプロペラファンとした場合には第１開口部１７を吐き出し口、第２開口部１８を吸い込み口としても良い。
【００３２】
また、薬剤収納容器３の表面板２０における第１通気部６の周囲及び裏面板２１における第２通気部７の周囲に図４に仮想線で示すようにシール材２５を設け、図２に示すように第２位置で支持した場合には第１通気部６、第２通気部７が確実に閉塞されるようにしても良い。
【００３３】
このようであるから、前記支持片２３、横片２４を持って薬剤収納容器３を持ち上げて容器支持部５から取り出し、周方向に１８０度回転して再び容器支持部５に支持することで、薬剤収納容器３を第１位置、第２位置とすることができ、その操作が容易である。
【００３４】
次に、本発明の第２の実施の形態を説明する。この実施の形態は薬剤収納容器３を容器支持部５に第１位置と第２位置に回転自在に取付けたことが、第１の実施の形態と相違し、他の構成は第１の実施の形態と同様である。
図６に示すように、容器支持部５は、薬剤収納容器３を回転自在に支承する形状とする。
例えば、装置本体１を一側縦壁１０と他側縦壁１１と一端縦壁１３と他端縦壁１４と上壁１５と下壁１６で中空部１ａを有する箱形状で、その一側縦壁１０に第１開口部１７を有すると共に、その一側縦壁１０における第１開口部１７の下開口縁１７ａに沿って半円筒形板３０を一体的に設け、この半円筒形板３０に半円板３１を一体的に設けて底面が半円形の容器支持部５を形成する。つまり、半円板３１が一側面５ａで、一側縦壁１０が他側面５ｂで、半円筒形板３０が周面５ｃである。
この半円形板３１の上端面３１ａの径方向中央部に半円形の凹部３２を形成する。
【００３５】
図７に示すように、薬剤収納容器３の周面板２２を半円筒形板３０に回転自在に接する円筒形状とし、表面板２０の中心部に、前記凹部３２に嵌まり込む支軸３３を設けることで、薬剤収納容器３が容器支持部５に回転自在に取付けできるようにする。
前記周面板２２に、ストッパとして突片３４を設け、この突片３４が半円筒形板３０の一端上面３０ａに当接すると第１位置、他端上面３０ｂに当接すると第２位置となるようにする。
【００３６】
このようにすることで、薬剤収納容器３を回転するだけで第１位置、第２位置とすることができる。
【００３７】
前記ストッパは、図８に示すように表面板２０の径方向一側寄りに設けた突出片３５とし、この突出片３５が半円形板３１の上端面３１ａに当接することで第１位置、第２位置となるようにしても良い。
【００３８】
図９に示すように、半円形板３１の上端面３１ａの径方向中央部に突片３６を設け、この突片３６と一側縦壁１０とに支承穴３７を相対向して形成する。
図１０に示すように、薬剤収納容器３の表面板２０、裏面板２１における中央部に回転支承部、例えば突起３８を設け、この突起３８を前記支承穴３７に回転自在に嵌合することで、薬剤収納容器３を容器支持部５に回転自在に支承しても良い。この場合には周面板２２が半円筒形板３０の内面と離れていても良い。
【００３９】
この実施の形態では、周面板２２を指でこするようにして薬剤収納容器３を回転するので、その周面板２２を摩擦抵抗大とする、例えば図１０に示すように凹凸２２ａを有するものとする。
【００４０】
また、図１０に示すように、周面板２２に一対の円孤状突起部２９を設け、第１位置、第２位置とした時にこの一対の円孤状突起部２９が半円筒形板３０の両端内面３０ｃ（つまり、容器支持部５の両端開口縁）に圧接して周面板２２と半円筒形板３０の両端内面３０ｃとの間を気密するようにしても良い。
このようにすることで、薬剤収納容器３を第１位置として使用する時に、その薬剤収納容器３の内部に効率良く空気が流通し、第２位置として休止する時には薬剤収納容器３の内部に空気が流通することを確実に防止し、揮散性薬剤４が自然に気中に放出されることを確実に防止できる。
【００４１】
以上の各実施の形態では薬剤収納容器３を１８０度回転して第１位置、第２位置としたが、１８０度よりも小さな角度だけ回転することで第１位置、第２位置とすることもできる。
例えば、図１１に示すように容器支持部５の両側面を薬剤収納容器３の表面３ａ、裏面３ｂよりも大きくする。例えば、半円筒形板３０に円板４０を形成して容器支持部５の一側面５ａとすると共に、装置本体１の一側縦板１０の円板４０と対向した部分を容器支持部５の他側面５ｂとする。
前記円板４０に、その中心部から外周部に向けて第１開口４１を周方向に間隔を置いて放射状に複数形成する。前記一側縦壁１０の円板４０と対向した部分にも、その中心部から外周部に向けて第２開口４２を周方向に間隔を置いて放射状に複数形成して前述の第１開口部１７とする。
この第１開口４１と第２開口４２は周方向に位置がずれている。
【００４２】
図１２（ａ）、（ｂ）に示すように、薬剤収納容器３の表面板２０、裏面板２１に、その中央部から外周部に向けて複数の第３・第４開口４３，４４を周方向に間隔を置いて放射状にそれぞれ形成して第１通気部６、第２通気部７とする。
この第３開口４３と第４開口４４は周方向に位置がずれている。そして、前記第１開口４１と第３開口４３が一致した時に第２開口４２と第４開口４４が一致して前述の第１位置となる。
前記第１開口４１と第３開口４３が一致しない時には第２開口４２と第４開口４４が一致せずに第３・第４開口４３，４４が閉塞されて前述の第２位置となる。
【００４３】
この実施の形態では、第１〜第４開口４１〜４４は３０度の開口幅で３０度間隔で位置がずれ、６コ形成してある。
よって、薬剤収納容器３を３０度回転することで第１位置又は第２位置となる。
【００４４】
前述の各実施の形態では、薬剤収納容器３を回転して第１位置、第２位置としたが、スライドして第１位置、第２位置としても良い。
例えば、図１３と図１４に示すように容器支持部５に薬剤収納容器３を第１位置と第２位置に亘ってスライド可能に支持する。
容器支持部５の一側面５ａと他側面５ｂにスリット状の第１開口５１と第２開口５２を上下方向に間隔を置いてそれぞれ形成し、第２開口５２で第１開口部１７とする。
薬剤収納容器３を表面３ａと裏面３ｂにスリット状の第３開口５３と第４開口５４を上下方向に間隔を置いてそれぞれ形成し、第１通気部６、第２通気部７とする。
【００４５】
そして、図１３に示す第１位置の時には第１開口５１と第３開口５３、第２開口５２と第４開口５４が連通し、図１４に示す第２位置の時には第３・第４開口５３，５４がそれぞれ閉塞されるようにする。
【００４６】
また、図示は省略するが薬剤収納容器３を左右方向にスライドして第１位置と第２位置としても良い。
【００４７】
本発明に用いる揮散性薬剤４としては、常温、送風などの条件で揮散する殺虫剤、忌避剤、害虫成長制御剤、芳香消臭剤、消臭剤、防カビ剤、防菌剤などが挙げられる。
【００４８】
【発明の効果】
請求項１に係る発明によれば、薬剤収納容器３を第１位置で支持することで、第１通気部６が大気に開口し、かつ第２通気部７が開口部１７に連通するので、送風機２を駆動することで、開口部１７、第２通気部７、薬剤収納容器３内部、第１通気部６に空気が流通するから、揮散性薬剤４を気中に放散できる。

BACKGROUND OF THE INVENTION
More specifically, the present invention relates to a blown-type drug releasing device that releases a volatile drug into the air using a blower, and more specifically, the volatile drug is naturally released into the air when the use is stopped after being used once. It is related with the ventilation type | formula medicine diffusion apparatus which can prevent.
[0002]
[Prior art]
Patent Document 1 includes a device main body having a suction port and a discharge port, a blower provided in the device main body, and a volatile chemical. The volatile chemical is blown by driving the blower to discharge the volatile chemical. An air blowing type drug diffusion device that discharges from the mouth into the air is disclosed.
[0003]
Patent Document 2 discloses an air blowing type medicine diffusion device in which a lid is provided on an air intake window and an air discharge window of an apparatus main body so as to be freely opened and closed.
[0004]
[Patent Document 1]
Japanese Patent Laid-Open No. 6-343681 [Patent Document 2]
Utility Model Registration No. 3027928 Publication
[Problems to be solved by the invention]
The blown medicine diffusion device disclosed in Patent Document 1 is a volatilizing drug set at the time when the blower is stopped and the use is stopped when the blower is set in the apparatus main body and the blower is driven and used. Since it communicates with the air from the suction port and the discharge port, it cannot be prevented that the volatile drug is naturally released into the air.
For this reason, the volatile drug is sequentially released into the air during the rest period and is reduced, which is useless.
[0006]
In order to solve the above-described problem, as disclosed in Patent Document 2, lids are provided at the suction port and the discharge port of the apparatus main body, and when in use, the lid is opened so that air can flow through the apparatus main body. It is conceivable that the lid is closed during the rest period so that the air does not flow in the apparatus main body.
[0007]
However, as described above, a lid must be provided, which increases the number of parts and increases the cost.
Further, since the two lids provided at the suction port and the discharge port are opened and closed to be in a use state and a rest state, the operation is troublesome.
[0008]
The present invention has been made in view of the above-mentioned problems, and the object thereof is to prevent the volatilizing drug from being naturally released into the air during the rest period, and at a low cost and with a simple operation. It is providing the ventilation type | formula medicine diffusion apparatus which can be made into a use state and a dormant state.
[0009]
[Means for Solving the Problems]
The first invention includes an apparatus main body 1 having a container support 5, a blower 2 provided in the apparatus main body 1, a medicine storage container 3 supported by the container support 5, and the medicine storage container 3. Equipped with a stored volatile chemical 4,
The container support portion 5 has another side surface 5b having an opening 17 through which air flows by driving the blower 2, and one side surface 5a facing the other side surface 5b with a gap therebetween,
The medicine container 3 is in contact with one side surface 5a of the container support portion 5 and is in contact with the surface 3a having the first ventilation portion 6 and the other side surface 5b of the container support portion 5 and the second ventilation portion 7.
