Description

【０００１】
【発明の属する技術分野】
本発明は、芳香剤、消臭剤、芳香消臭剤、除菌剤、殺虫剤、害虫忌避剤などの揮散性の薬剤を揮散させる器具であって、室内の適所に配置して自然に揮散させたり、または必要に応じて送風し強制揮散させることを兼ね備えた薬剤揮散器具に関するものである。
【０００２】
【従来の技術】
従来、芳香剤などの揮散性の薬剤を揮散させる薬剤揮散器具には、器具内に収容した液状芳香剤など薬剤を吸上げ芯を介して吸上げ揮散させる、或いは器具内に収容したゲル状芳香剤など薬剤を開放部分から揮散させる、などの自然に揮散させる自然揮散方式の薬剤揮散器具がある。
また、ファンを備えた器具内に芳香剤など薬剤を含む通気性の薬剤保持体などを配置し、ファンによる発生気流で薬剤を拡散させる、などの強制的に揮散させる強制揮散方式の薬剤揮散器具がある。
【０００３】
【発明が解決しようとする課題】
前者の自然揮散方式の薬剤揮散器具は、持続性に優れているが拡散性がないという欠点がある。
後者の強制揮散方式の薬剤揮散器具は、拡散性には優れているが高濃度の薬剤が室内に分布するという欠点がある。
前述のように、揮散方式の異なる２つの薬剤揮散器具は、相反する長短を示し、またそれぞれ相補的な長所を有しているため、自然揮散と強制揮散の両方の揮散方式を備え、持続性及び速効的拡散性を得ることができる薬剤揮散器具とすれば、二方式の薬剤揮散器具を別個に準備することなく、１つの薬剤揮散器具で各長所を使い分け使用することができ非常に便利である。
しかし、従来そのような薬剤揮散器具は提案されていない。
【０００４】
例えば、実公昭５５−５１４７１号公報に開示された自然揮散方式の薬剤揮散器具において、その内箱内にファンを設置して強制揮散させても多量の薬剤を揮散できないし、そのファンによる空気の流れが薬剤の外部への放出方向と反対となるから、多量の薬剤を効率良く大気に放出ができない。
また、自然揮散した場合にはファンが薬剤の放出の妨げとなる。
【０００５】
また、特開２０００−１８９５０７号公報に開示された強制揮散方式の薬剤揮散器具において、ファンを停止すれば自然揮散方式とすることが可能であるが、揮散薬剤の大気への放出流路が狭く、自然揮散した薬剤が大気に放出され難い。
【０００６】
このように、従来の自然揮散方式の薬剤揮散器具にファンを取付けただけでは多量の薬剤を効率良く大気に放出できないし、従来の強制揮散方式の薬剤揮散器具のファンを停止しただけでは自然揮散した薬剤を効率良く大気に放出できない。
【０００７】
本発明は、前述の課題を解決するためになされたものであり、その目的は、自然揮散時に薬剤を効率良く大気に放出できると共に、強制揮散時に多量の薬剤を効率良く大気に放出でき、常時は、自然に芳香剤等の揮散性の薬剤を揮散させ長期にわたって薬剤効果を持続させると共に、室内全体或いは短時間に高い薬剤効果を得たい場合には、強制揮散に切り替えファンにより芳香剤等の揮散性の薬剤の拡散を行うことができる薬剤揮散器具を提供することである。
【０００８】
【課題を解決するための手段】
第１の発明は、上面に吸込み部１ａ、側面に吐出部１ｂを有する送風容器体１と、
この送風容器体１内に設けられた送風機２と、
前記送風容器体１の上部に設けられ、上面のほぼ全面に揮散用開口部３ａを有する薬剤容器体３と、
前記薬剤容器体３内に収容され、揮散性の薬剤を含有した製剤４と、
前記送風容器体１の上部に設けられ、薬剤容器体３を覆うと共に、上面に吸込み用開口部５ａを有するカバー体５を備え、
前記吸込み部１ａと吸込み用開口部５ａが気流流路で連通し、
前記吸込み用開口部５ａは、薬剤容器体３の揮散用開口部３ａのほぼ全域と相対向し、外気をほぼ中央部から集中的に吸込む形状であることを特徴とする薬剤揮散器具である。
【０００９】
第２の発明は、第１の発明において、カバー体５における吸込み用開口部５ａの中央寄りに沿って気流規制板３８を下向きに設けた薬剤揮散器具である。
【００１０】
第３の発明は、第１の発明において、カバー体５の上面にスリット状の開口部３３を放射状に複数形成し、各スリット状の開口部３３の幅は外周寄りから中央寄りに向けて順次大きく、各スリット状の開口部３３の中央寄り部分が連続して中央孔３４を形成することで吸込み用開口部５ａとした薬剤揮散器具である。
【００１１】
第４の発明は、第２の発明において、カバー体５の上面における中央部分に中央孔３６を形成し、その中央孔３６よりも外周寄りにスリット状の開口部３７を放射状に複数形成して吸込み用開口部５ａとし、
前記中央孔３６の周縁に沿ってリング形状の気流規制板３８を下向きに設けた薬剤揮散器具である。
【００１２】
第５の発明は、第１〜第４いずれか１つの発明において、薬剤容器体３の外周面とカバー体５の内周面との間に第２空間７を形成し、送風容器体１の上面と薬剤容器体３の下面との間に、前記第２空間７と連通した第３空間８を形成し、
前記第２空間７を吸込み用開口部５ａに連通すると共に、前記第３空間８を吸込み部１ａに連通して気流流路とし、
前記第２空間７、第３空間８の幅を１０ｍｍ以下とした薬剤揮散器具である。
【００１３】
【作用】
第１の発明によれば、送風機２を停止することで自然揮散方式の薬剤揮散器具となる。
この時、製剤４の上面４ａから揮散した薬剤は揮散用開口部３ａから上昇し、カバー体５の吸込み用開口部５ａから直接大気に放出されるから、送風機２などが邪魔にならない。
しかも、カバー体５の吸込み用開口部５ａは薬剤容器体３の揮散用開口部３ａ（つまり、製剤４の上面４ａ）のほぼ全域と相対向しているから、製剤４の上面４ａから揮散した薬剤はスムーズに大気に放出される。
したがって、自然揮散時に揮散した薬剤を効率良く大気に放出できる。
【００１４】
また、送風機２を駆動することで吸込み用開口部５ａのほぼ中央部から集中的に外気を吸込み、その吸込みされた外気は製剤４の上面４ａにおけるほぼ中央部に当たり、製剤４の上面４ａに沿って外周側に流れるので、製剤４の上面４ａのほぼ全面から均一に薬剤が多量に揮散する。
この揮散した薬剤を含む空気は気流流路、吸込み部１ａを通り、吐出部１ｂから大気に放出される。
したがって、強制揮散時に薬剤が多量に揮散するから、多量の薬剤を効率良く大気に放出できる。
【００１５】
第２の発明によれば、送風機２を駆動して吸込み用開口部５ａのほぼ中央部から集中的に吸込みされた外気は、気流規制板３８によって側方に流れることが規制されて製剤４の上面４ａに向けて流れる。
したがって、より一層多量の薬剤を揮散できるから、強制揮散時に多量の薬剤をより一層効率良く大気に放出できる。
【００１６】
第３の発明によれば、自然揮散時に揮散した薬剤は、スリット状の開口部３３、中央孔３４から大気に放出されるので、その放出量は少なく、長期間にわたって薬剤を大気に放出することができる。
スリット状の開口部３３の幅は外周寄りから中央寄りに向けて順次大きいから、強制揮散時に吸込みされる外気の量は外周寄りが少なく、中央寄りに向けて順次多くなるので、ほぼ中央部から集中的に吸込みされる。
【００１７】
第４の発明によれば、強制揮散時に中央孔３６から主として外気が吸込みされ、その吸込みされた外気はリング形状の気流規制板３８で真下に向けた流れに規制される。
よって、吸込んだ外気のほとんどが製剤４の上面４ａにおけるほぼ中央部に当たるから、より一層多量の薬剤を揮散できる。
【００１８】
第５の発明によれば、強制揮散時に気流流路を通る空気の速度が大幅に遅くならないので、短時間に多量の薬剤を大気に放出できる。
【００１９】
【発明の実施の形態】
図１に示すように、送風容器体１と、この送風容器体１内に設けた送風機２と、前記送風容器体１の上部に設けた薬剤容器体３と、この薬剤容器体３に収容した製剤４と、前記送風容器体１の上部に設けられ前記薬剤容器体３を覆うカバー体５で薬剤揮散器具を形成している。
前記送風容器体１は、上面に吸込み部１ａ、側面に吐出部１ｂを有する。
前記送風機２はファン２ａと、そのファン２ａを駆動する電動モータ２ｂを有する。
前記薬剤容器体３は上面のほぼ全面が開口し、揮散用開口部３ａを有する。
製剤４は揮散性の薬剤を含有し、その上面４ａが薬剤容器体３の揮散用開口部３ａから外部に露出する。
【００２０】
前記カバー体５の上面に吸込み用開口部５ａを有する。この吸込み用開口部５ａは、前記薬剤容器体３の揮散用開口部３ａのほぼ全域と相対向し、外周寄りから中央部に向けて開口面積が順次大きい形状、つまり吸込み用開口部５ａは前記送風機２を駆動した時（強制揮散の時）には、外気をほぼ中央部から集中的に吸い込み、送風機２を停止した時（自然揮散の時）には、薬剤容器体３の揮散用開口部３ａの全域から揮散した薬剤をスムーズに大気に放出できる形状である。
【００２１】
前記薬剤容器体３の上面とカバー体５との間に第１空間６を有する。この第１空間６は吸込み用開口部５ａと製剤４の上面４ａに連通する。
前記薬剤容器体３の外周面とカバー体５の内周面との間に第２空間７を有する。この第２空間７の上部は前記第１空間６に連通している。
前記送風容器体１の上面と薬剤容器体３の下面との間に第３空間８を有する。この第３空間８の上部は前記第２空間７に連通し、下部は前記吸込み部１ａに連通している。
これにより、第２空間７と第３空間８で気流流路を形成している。
【００２２】
次に各部材の具体形状の一例を図１と図２に基づいて説明する。
前記送風容器体１は、上面板１０と周面板１１と下面板１２と隔板１３で上部室１４ａと下部室１４ｂを有する断面円形の筒形状である。周面板１１の上部寄りに雄ねじ１５が形成してある。
前記上面板１０の中央部に円形の孔１６が形成され、前記吸込み部１ａとしてある。この上面板１０の外周寄りに設置台１７が周方向に間隔を置いて複数設けてある。この設置台１７はＬ字形状であるが、他の形状でも良い。
前記周面板１１にスリット状の開口部１８が複数形成され、この開口部１８は上部室１４ａに開口し、前記吐出口１ｂとしてある。
前記上部室１４ａに送風機２が設けてある。
前記下部室１４ｂに電池１９が収納してあり、その電池１９で電動モータ２ｂを駆動する。電動モータ２ｂは商用電源で駆動しても良い。
【００２３】
前記薬剤容器体３は上面のほぼ全面が開口した断面円形の容器２０と、蓋２１を備え、この実施の形態では蓋２１はプルトップ２１ａを引くことで開放できる。つまり、薬剤容器体３はプルトップ缶である。
前記容器２０は、前記複数の設置台１７の低部内周寄り１７ａと高部外周寄り１７ｂとの段部１７ｃに嵌合すると共に、その下面が複数の設置台１７の低部内周寄り１７ａに接して取付けられる。
これにより、容器２０の下面（薬剤容器体３の下面）と上面板１０（送風容器体１の上面）との間に前述の第３通路８を形成する。
【００２４】
前記製剤４はゲル状である。
前記カバー体５は周面板３０と上面板３１で断面円形の筒状で、その周面板３０の下部寄り内面に前記雄ねじ１５と螺合する雌ねじ３２が形成してある。
この雌ねじ３２を雄ねじ１５に螺合することでカバー体５を送風容器体１の上部に着脱自在に取付けられる。
前記周面板３０は前記容器２０よりも大径で、その周面板３０の内周面と前記容器２０の外周面との間に前記第２空間７を形成する。
前記周面板３０は容器２０よりも長く、その上面板３１と容器２０の上面との間に前記第１空間６を形成する。
【００２５】
前記上面板３１の中央部から外周寄りに亘って複数のスリット状の開口部３３が周方向に間隔を置いて放射状に形成され、前記吸込み用開口部５ａとしてある。
この各開口部３３の幅は外周寄りから中央寄りに向けて順次大きく、その外周寄り部は薬剤容器体３の揮散用開口部３ａの周縁と略同一である。前記各開口部３３の中央寄りが連続して小さな中央孔３４を形成している。
【００２６】
このようであるから、自然揮散時に製剤４の上面４ａにおけるほぼ全面から薬剤が揮散し、揮散した薬剤は各開口部３３からスムーズに大気に放出される。したがって、自然揮散時に薬剤を効率良く大気放出できる。
また、送風機２を駆動することで各開口部３３及び中央孔３４を通して外気が吸込みされ、その各開口部３３の外周寄りからの吸込み量は少なく、中央寄りの吸込み量が多く、中央孔３４から最も多量に吸込みされる。
よって、外気はほぼ中央部から集中的に吸込みされる。
【００２７】
前述のようにして吸込みされた外気は製剤４の上面４ａにおける中央部に当たり、その上面に沿って外周寄りにスムーズに流れ、第１空間６、第２空間７、第３空間８、大径孔１６を流れて開口部１８から大気に吐出される。
したがって、製剤４の上面４ａから薬剤を均一に多量に揮散させることができ、強制揮散時に多量の薬剤を効率良く大気に放出できる。
【００２８】
前記第２空間７、第３空間８の幅（外気流通方向と直角方向の寸法）は１０ｍｍ以下で最小１ｍｍである。
これによって、送風機２によって第２空間７、第３空間８を流通する空気の速度が大幅に遅くなることがなく、短時間に多量の薬剤を大気に放出できる。
つまり、第２空間７、第３空間８の幅は、強制揮散の目的である薬剤の速効的揮散、速効的拡散、多量揮散などを達成する気流速度を得るために、１０ｍｍ以下である。１０ｍｍ以上の場合、広い部屋や開放した部屋においてそれぞれの目的を充分に満足することができない。ただし、業務用分野などで使用する大型送風機では１０ｍｍ以上でも目的が達成できる。
一方、１０ｍｍ以下の場合は、薬剤容器体３の大きさやカバー体５の吸込み用開口部５ａの大きさによって多少異なるがあまり狭くなると薬剤が搬送されず空気だけの出入りが起こり、最小１ｍｍ以上が好ましい。
【００２９】
次に、本発明の第２の実施の形態を図３と図４に基づいて説明する。なお、第１の実施の形態と同一の部分は符号を同一として説明を省略し、異なる部分のみを詳細に説明する。
送風容器体１の周面板１１の上部寄りに小径部４０を形成し、上面板１０にスリット状の凹部４１を放射状に複数形成する。
薬剤容器体３は、上面が開口した容器２０の開口周縁部に空気不透過性フィルム２２を熱溶着して容器２０を密封し、その容器２０の下面に、前記凹部４１に嵌合する凸部２３を放射状に複数設けた形状である。
そして、凸部２３を凹部４１に嵌合することで送風容器体１の上面板１０に薬剤容器体３の容器２０を取付け、その容器２０の下面と上面板１０との間に第３空間８を形成する。
使用時には空気不透過性フィルム２２を剥離して容器２０を開封し、内部の製剤４を露出させる。
【００３０】
カバー体５の周面板３０の下端部分を薄肉として段部３５を形成し、その薄肉部分を小径部４０に嵌合して段部３５を上面板１０に当接してカバー体５を送風容器体１の上部に着脱自在に取付ける。
【００３１】
カバー体５の上面板３１の中央部に大径の中央孔３６を形成し、外周寄りにスリット状の開口部３７を放射状に複数形成して吸込み用開口部５ａとする。この開口部３７の幅は外周寄りから中央寄りに向けて順次大きい。中央孔３６は複数のスリット状開口部としても良い。
このようにすることで、自然揮散時に製剤４の上面４ａから揮散した薬剤は中央孔３６、複数のスリット状の開口部３７からスムーズに大気に放出される。
強制揮散時には主として中央孔３６から外気が吸込みされるから、製剤４の上面４ａにおけるほぼ中央部に集中的に外気が当たる。
【００３２】
前記上面板３１の下面における中央孔３６の周縁部分に気流規制板３８が下向きに設けてある。
この気流規制板３８はリング形状である。なお、リング形状に限ることはなく、複数の規制板を中央孔３６に沿って設けても良い。
このようにすることで、中央孔３６から吸込みされた外気は気流規制板３８でほぼ真下に向けて流れるように規制されるから、製剤４の上面４ａにおけるほぼ中央部により一層集中して外気が当たる。
【００３３】
図５に示すように、送風容器体１の上面板１０に凹陥部４２を形成し、薬剤容器体３の平坦な下面を上面板１０に置くことで、その下面と凹陥部４２との間に第３空間８を形成するようにしても良い。
【００３４】
各実施の形態において、電池１９は送風容器体１の側部などに収納しても良い。
また、各実施の形態において、カバー体５の上面板３１を中央部が低く外周部が高いほぼ漏斗形状として、外気がより一層中央部から集中的に吸い込みされるようにしても良い。
【００３５】
前記各実施の形態において、送風容器体１、薬剤容器体３、カバー体５の形状は、特に限定されることなく、円形・四角形・多角形・菱形など自由に設計できる。ただし、送風容器体１は設置状態が安定した形状とする必要がある。
また、送風容器体１、薬剤容器体３、カバー体５の材料としては、合成樹脂、陶磁器、金属、、紙、木材など公知のものが使用できる。
【００３６】
本発明に用いる揮散性の薬剤は、自然下で揮散する芳香剤、芳香消臭剤、消臭剤、防菌・防黴剤、除菌剤、防虫剤、害虫忌避剤、害虫成長阻害剤、殺虫剤などが挙げられる。
【００３７】
本発明に用いる製剤は、形状として、多量の揮散性の薬剤を含有し、取扱いが簡便であればよく、例えばゲル状、ジェル状、粒状、粉状、マット状、綿状、繊維状などが例示される。
製剤の材料としては、自然下で含有された揮散性薬剤を放出するものであればよく、例えば多孔質無機物質および有機物質、パルプ材、ゲル化材、合成樹脂などが例示される。
送風機のファンとしては、シロッコファンが好ましいが、軸流ファン、プロペラファンを用いることもできる。
【００３８】

この揮散した薬剤を含む空気は気流流路、吸込み部１ａを通り、吐出部１ｂから大気に放出される。
したがって、強制揮散時に薬剤が多量に揮散するから、多量の薬剤を効率良く大気に放出できる。
【００４０】
請求項２に係る発明によれば、送風機２を駆動して吸込み用開口部５ａのほぼ中央部から集中的に吸込みされた外気は、気流規制板３８によって側方に流れることが規制されて製剤４の上面４ａに向けて流れる。

BACKGROUND OF THE INVENTION
The present invention is a device that volatilizes volatile chemicals such as fragrances, deodorants, fragrance deodorants, disinfectants, insecticides, pest repellents, etc. The present invention relates to a chemical volatilization device that can be forced or volatilized by blowing or blowing as necessary.
[0002]
[Prior art]
Conventionally, in a chemical volatilization device that volatilizes a volatile chemical such as a fragrance, a liquid fragrance or the like contained in the device is sucked and volatilized through a suction core, or a gel-like fragrance contained in the device. There are natural volatilization chemical volatilization devices that volatilize naturally, such as volatilizing chemicals from the open part.
Also, a forced volatilization chemical volatilization device such as a breathable chemical carrier containing a fragrance and other chemicals in a device equipped with a fan, and forcing the volatilization of the chemical by the air flow generated by the fan. There is.
[0003]
[Problems to be solved by the invention]
The former natural volatilization type chemical volatilization device has a drawback that it is excellent in sustainability but is not diffusible.
The latter forced volatilization type chemical volatilization device is excellent in diffusibility, but has a drawback that a high concentration of chemical is distributed in the room.
As mentioned above, two chemical volatilization devices with different volatilization methods exhibit conflicting advantages and disadvantages, and have complementary advantages, so they have both volatilization methods of natural volatilization and forced volatility, and are sustainable. And if it is a drug volatilization device that can obtain fast diffusivity, it is very convenient that one medicinal volatilization device can use each advantage separately without preparing two types of drug volatilization devices separately. is there.
However, no such chemical volatilization device has been proposed.
[0004]
For example, in a natural volatilization method chemical volatilization device disclosed in Japanese Utility Model Publication No. 55-51471, a large amount of chemicals cannot be volatilized even if a fan is installed in the inner box and forced volatilization is performed. Since the flow is opposite to the release direction of the drug, a large amount of drug cannot be efficiently released to the atmosphere.
In addition, when volatilized spontaneously, the fan prevents the drug from being released.
[0005]
In addition, in the forced volatilization method chemical volatilization device disclosed in Japanese Patent Application Laid-Open No. 2000-189507, it is possible to adopt a natural volatilization method by stopping the fan, but the discharge channel of the volatilization chemical to the atmosphere is narrow. , Naturally volatilized drugs are difficult to be released into the atmosphere.
[0006]
In this way, a large amount of chemicals cannot be efficiently released to the atmosphere simply by attaching a fan to a conventional volatilization-type chemical volatilization device, and natural volatilization can be achieved simply by stopping the fan of a conventional volatilization-type chemical volatilization device. Can not be released efficiently into the atmosphere.
[0007]
The present invention has been made in order to solve the above-described problems, and its purpose is to efficiently release a drug to the atmosphere at the time of volatilization and to efficiently release a large amount of the drug to the atmosphere at the time of forced volatilization. When volatilizing volatile chemicals such as fragrances are volatilized and the chemical effect is sustained over a long period of time, and when it is desired to obtain a high chemical effect in the whole room or in a short time, switch to forced volatilization and use a fan. It is to provide a chemical volatilization device capable of diffusing a volatile chemical.
[0008]

[0013]
[Operation]
According to 1st invention, it becomes a natural volatilization type chemical volatilization instrument by stopping the air blower 2.
At this time, since the chemical volatilized from the upper surface 4a of the preparation 4 rises from the volatilization opening 3a and is directly released to the atmosphere from the suction opening 5a of the cover body 5, the blower 2 and the like do not get in the way.
Moreover, since the suction opening 5a of the cover body 5 is opposed to almost the entire area of the volatilization opening 3a of the drug container body 3 (that is, the upper surface 4a of the preparation 4), it volatilizes from the upper surface 4a of the preparation 4. The drug is released smoothly into the atmosphere.
Therefore, the chemicals volatilized during natural volatilization can be efficiently released to the atmosphere.
[0014]
Further, by driving the blower 2, the outside air is intensively sucked from the substantially central portion of the suction opening 5 a, and the sucked outside air hits the substantially central portion of the upper surface 4 a of the preparation 4, along the upper surface 4 a of the preparation 4. Therefore, a large amount of the drug is uniformly vaporized from almost the entire upper surface 4a of the preparation 4.
The air containing the volatilized medicine passes through the air flow channel and the suction part 1a and is discharged from the discharge part 1b to the atmosphere.
Accordingly, since a large amount of the chemical is volatilized during forced volatilization, a large amount of the chemical can be efficiently released to the atmosphere.
[0015]
According to the second invention, the outside air that is intensively sucked from the substantially central portion of the suction opening 5a by driving the blower 2 is restricted from flowing to the side by the air flow restriction plate 38, and the formulation 4 It flows toward the upper surface 4a.
Therefore, since a much larger amount of chemical | medical agent can be volatilized, a large amount of chemical | medical agents can be discharge | released to air | atmosphere more efficiently at the time of forced volatilization.
[0016]
According to the third invention, since the chemical volatilized at the time of natural volatilization is released to the atmosphere from the slit-shaped opening 33 and the central hole 34, the amount released is small and the drug is released to the atmosphere over a long period of time. Can do.
Since the width of the slit-shaped opening 33 gradually increases from the outer periphery toward the center, the amount of outside air sucked during forced volatilization is less at the outer periphery and gradually increases toward the center. Inhaled intensively.
[0017]
According to the fourth aspect of the invention, outside air is mainly sucked from the central hole 36 at the time of forced volatilization, and the sucked outside air is restricted by the ring-shaped air flow restricting plate 38 to flow downward.
Therefore, since most of the sucked outside air hits the substantially central portion of the upper surface 4a of the preparation 4, a much larger amount of medicine can be volatilized.
[0018]
According to the fifth invention, since the speed of the air passing through the air flow path is not significantly reduced during forced volatilization, a large amount of drug can be released to the atmosphere in a short time.
