Description

液体噴霧装置Liquid sprayer
　本発明は、芳香剤、消臭剤、除菌剤、殺菌剤等の各種液体をミストとして噴霧する液体噴霧装置に関する。 The present invention relates to a liquid spraying device that sprays various liquids such as air fresheners, deodorants, disinfectants, and bactericides as mist.
　従来、芳香あるいは消臭によってトイレなどの空間のエア環境を好ましい状態にする芳香器や芳香装置、あるいは、消臭剤を噴霧する消臭器や消臭装置などが開発されている。 Conventionally, fragrances and fragrance devices that make the air environment of spaces such as toilets favorable by fragrance or deodorization, or deodorizers and deodorizers that spray deodorants have been developed.
　上記の芳香器や消臭器の場合は、単に芳香剤や消臭剤を容器内に充填しただけである。例えば、芳香器では芳香剤を自然蒸発させて発散させるので、室内空間に部分的に芳香の強い所ができたり、芳香の弱い所ができたりする。特に、広い空間の場合は芳香が空間全体に均一に行きわたりにくい。その点は、消臭器の場合も同様である。 In the case of the above air freshener and deodorant, the container is simply filled with the air freshener and deodorant. For example, in an air freshener, the air freshener is naturally evaporated and released, so that a part with a strong fragrance may be created or a place with a weak fragrance may be formed in the indoor space. In particular, in the case of a large space, it is difficult for the fragrance to spread evenly throughout the space. The same applies to the deodorizer.
　上記の問題を解消するため、例えば、特許文献１では、一般家庭のトイレのような狭い空間はもとより、ホテルやレストランなどのトイレのような広い空間においても、芳香剤や消臭剤が均一に行き渡るような工夫がなされた芳香装置あるいは消臭装置として使用できる液体噴霧装置が開示されている。すなわち、吸込口と吹出口を有する本体ケースの内部に、液状芳香剤等を封入した容器を配置し、その容器内の液状芳香剤等が、本体ケースにおけるエアの吸込口と吐出口との間のエア流路部へ発散するように配置される。そして、エア流路部に配置される電動ファンの駆動により、前記吸込口から前記吹出口までの間でエアの流れを生じさせる。 In order to solve the above problem, for example, in Patent Document 1, the fragrance and deodorant are uniformly applied not only in a narrow space such as a toilet in a general household but also in a wide space such as a toilet in a hotel or a restaurant. A liquid spraying device that can be used as an fragrance device or a deodorizing device that has been devised to spread is disclosed. That is, a container containing a liquid air freshener or the like is placed inside the main body case having a suction port and an air outlet, and the liquid air freshener or the like in the container is between the air suction port and the discharge port in the main body case. It is arranged so as to diverge to the air flow path portion of. Then, by driving the electric fan arranged in the air flow path portion, an air flow is generated from the suction port to the air outlet.
　電動ファンが駆動すると、エアが吸込口からエア流路部へ吸い込まれる。そのエアは容器内の液状芳香剤等を強制的に蒸発させて発散させ、吹出口から外部へ吹き出す。そのようにしてトイレなどの室内を芳香で満たしたり、消臭したりする。 When the electric fan is driven, air is sucked into the air flow path from the suction port. The air forcibly evaporates and dissipates the liquid air freshener and the like in the container, and blows it out from the outlet. In this way, the room such as a toilet is filled with fragrance and deodorized.
　一方、特許文献２では、芳香剤や消臭剤を吸い上げる液体ノズルの吐出口付近に、エアノズルの噴射口を配置し、エアノズルからエアを噴射する際に液体ノズルの吐出口から吐出される液体を吹き飛ばすタイプの液体噴霧装置（エアフレッシュナー）が開示されている。 On the other hand, in Patent Document 2, an injection port of an air nozzle is arranged near the discharge port of a liquid nozzle that sucks up an air freshener or a deodorant, and when air is injected from the air nozzle, the liquid discharged from the discharge port of the liquid nozzle is discharged. A blow-off type liquid sprayer (air freshener) is disclosed.

　特許文献１に開示された芳香剤や消臭剤を発散させる装置は、広い空間に対して芳香等を全体に均一に行き渡らせることができる点では効果的であるが、容器から蒸発した芳香剤等の液体を電動ファンにて外部へ吹き出すので、蒸発しやすい成分だけが先に消費されやすい。そのため、時間経過に伴い、芳香等の効能が比較的早期に低下するという問題がある。 The device that dissipates the fragrance and deodorant disclosed in Patent Document 1 is effective in that the fragrance and the like can be evenly distributed over a wide space, but the fragrance evaporated from the container. Since the liquid such as the above is blown out by an electric fan, only the components that easily evaporate are likely to be consumed first. Therefore, there is a problem that the efficacy of fragrance and the like decreases relatively early with the passage of time.
　これに対し、特許文献２に開示のエアフレッシュナーの場合は、エアによって芳香剤等の液体を遠くへ吹き飛ばす構成であるため、特許文献１に記載の装置と比較して、液体のミストを長時間に亘って空中を漂わせ、芳香剤等の液体の効能が広いエリアでより長く働くという利点を有する。 On the other hand, in the case of the air freshener disclosed in Patent Document 2, since the liquid such as an air freshener is blown away by air, the mist of the liquid is longer than that of the apparatus described in Patent Document 1. It has the advantage of floating in the air over time and working longer in areas where liquids such as air fresheners are more effective.
　特許文献２のエアフレッシュナーは、筒状の液体ノズルに対し、その直交する方向に沿って筒状のエアノズルを配置して、液体ノズルから吐出される液体をエアノズルからのエアによって吹き飛ばす構造である。液体はエアによってミスト状に微細化されるが、液体ノズルの液体吐出口とエアノズルのエア吐出口との離間距離によってミストになった液体の粒子径に差がでる。しかし、特許文献２では、液体ノズルとエアノズルをそれぞれ単独で配置しており、両者の取り付け位置に、製品間でばらつく場合があり、製品によって、芳香の拡散範囲、拡散時間に差がでる場合がある。また、両者の取り付け位置の誤差により、液体とエアとの接触がうまくいかず、粒子径が比較的大きい状態のまま開口部から外部に放出されずに、ケース内面に付着してしまう場合もあった。 The air freshener of Patent Document 2 has a structure in which a tubular air nozzle is arranged along a direction orthogonal to the tubular liquid nozzle, and the liquid discharged from the liquid nozzle is blown off by the air from the air nozzle. .. The liquid is refined into a mist by air, but the particle size of the liquid that has become mist differs depending on the distance between the liquid discharge port of the liquid nozzle and the air discharge port of the air nozzle. However, in Patent Document 2, the liquid nozzle and the air nozzle are arranged independently, and the mounting positions of the two may vary between the products, and the diffusion range and diffusion time of the fragrance may differ depending on the product. is there. In addition, due to an error in the mounting positions of the two, the contact between the liquid and the air may not be successful, and the liquid may adhere to the inner surface of the case without being discharged from the opening to the outside while the particle size is relatively large. It was.
　本発明は上記に鑑みなされたものであり、芳香剤、消臭剤、除菌剤あるいは殺菌剤等の各種液体をより細かなミストとして噴霧でき、それらの液体の効能を、より広い空間に対してより均一に行きわたらせることができる液体噴霧装置を提供することを課題とする。また、本発明は、かかる課題に加え、ケース内面に付着する液体を低減することができる液体噴霧装置を提供することを課題とする。 The present invention has been made in view of the above, and various liquids such as air fresheners, deodorants, disinfectants or bactericides can be sprayed as finer mists, and the effects of these liquids can be applied to a wider space. It is an object of the present invention to provide a liquid spraying device capable of spreading the liquid more evenly. Another object of the present invention is to provide a liquid spraying device capable of reducing the amount of liquid adhering to the inner surface of the case, in addition to the above-mentioned problems.

　前記液体ノズル、前記エアノズル及び前記台座部が、いずれも合成樹脂の成形品であることが好ましい。 It is preferable that the liquid nozzle, the air nozzle, and the pedestal portion are all molded products of synthetic resin.
　本発明の液体噴霧装置は、エアノズル及び液体ノズルが、両者の周壁部に形成されたノズル用係合部同士を係合させることにより一体化でき、エアの吐出方向を液体の吐出方向に対して予め設定した角度で、かつ、エア吐出口と液体吐出口とが予め設定した距離の近接した位置関係とすることができる。そして、このように相互に係合されて一体化されたエアノズル及び液体ノズルは、液体ノズルの周壁部に形成した台座用係合部を台座部に設けたノズル取り付け部に取り付けることで、エアノズル及び液体ノズルを常に一定の位置に取り付けることができる。従って、エアノズル及び液体ノズルは、所定以下の微細な粒子径のミストを作り出すのに適した位置関係で容易に取り付けることができ、ミストの拡散距離、拡散範囲を安定させることができ、製品間における噴霧量のばらつきが小さくなる。その結果、粒子径の大きなミストが作り出されることが少なくなり、開口部から外部に拡散せずに、ケース内面に付着するミスト量を減少させることができ、液体の無駄が減り、液体の使用量を抑制できる。エアノズル、液体ノズル及び台座部は、合成樹脂の成形品とすることにより、寸法精度が高くなり、各部材の位置関係、取り付け位置がさらに安定化し、ミストの噴霧量のばらつきもより少なくなる。 In the liquid spraying device of the present invention, the air nozzle and the liquid nozzle can be integrated by engaging the nozzle engaging portions formed on the peripheral wall portions of the two, and the air discharge direction is set with respect to the liquid discharge direction. The positional relationship may be such that the air discharge port and the liquid discharge port are close to each other at a preset angle and a preset distance. The air nozzle and the liquid nozzle, which are integrally engaged with each other in this way, are attached to the nozzle mounting portion provided on the pedestal portion by attaching the pedestal engaging portion formed on the peripheral wall portion of the liquid nozzle to the air nozzle and the liquid nozzle. The liquid nozzle can always be mounted in place. Therefore, the air nozzle and the liquid nozzle can be easily attached in a positional relationship suitable for producing a mist having a fine particle size of a predetermined value or less, the diffusion distance and the diffusion range of the mist can be stabilized, and the mist can be dispersed between products. The variation in the amount of spray is reduced. As a result, mist with a large particle size is less likely to be produced, the amount of mist adhering to the inner surface of the case can be reduced without diffusing from the opening to the outside, waste of liquid is reduced, and the amount of liquid used is reduced. Can be suppressed. By using synthetic resin molded products for the air nozzle, liquid nozzle and pedestal, the dimensional accuracy is improved, the positional relationship and mounting position of each member are further stabilized, and the variation in the amount of mist sprayed is further reduced.
　また、液体ノズルの液体吐出口を、開口部を通過するケースの内表面に沿った内側仮想線よりも外方、好ましくは、開口部を通過するケースの内表面に沿った内側仮想線と開口部を通過するケースの外表面に沿った外側仮想線とに挟まれた開口部を形成する周縁部の厚みの範囲内に位置するように設けることにより、液体吐出口の位置が上記内側仮想線よりも外方、好ましくはケースの開口部とほぼ面一となり、その位置からエアによって外部に吹き飛ばされることで、ケース内へのミストの付着をより少なくすることができる。この場合、エアノズルのエア吐出口も同様の位置とすることで、ミストのケース内への付着抑制効果をより高めることができる。 Also, the liquid discharge port of the liquid nozzle is located outward of the inner virtual line along the inner surface of the case passing through the opening, preferably the inner virtual line and opening along the inner surface of the case passing through the opening. By providing the liquid discharge port so as to be located within the thickness range of the peripheral portion forming the opening sandwiched between the outer virtual line along the outer surface of the case passing through the portion, the position of the liquid discharge port is the inner virtual line. The mist can be less adhered to the inside of the case by being blown to the outside by air from the outside, preferably substantially flush with the opening of the case. In this case, by setting the air discharge port of the air nozzle at the same position, the effect of suppressing the adhesion of mist into the case can be further enhanced.
　また、台座部に、液体供給チューブが通過可能なチューブ用スリットを設けることで、キンクによる噴霧不良を抑制できる。 In addition, by providing a tube slit through which the liquid supply tube can pass, the spray failure due to kink can be suppressed.

Is provided. The container support shelf 22 is elastically supported on the upper shelf 21 via an elastic member 21a such as a coil spring. A liquid container 12 containing an air freshener, a deodorant, or the like is placed on the container support shelf 22. A body cover 30 having a substantially U-shaped cross section is detachably provided so as to cover the front surface and both side surfaces.
　上部カバー４０は、胴部カバー３０の上方側を覆い、側面視で、後方から前方に向かって下方に傾斜しかつ湾曲するように形成されており、前方壁には、噴霧機構５０から噴射するミスト状の液体を外部へ放出するための開口部４１が形成されている。 The upper cover 40 covers the upper side of the body cover 30, and is formed so as to be inclined and curved downward from the rear to the front in a side view, and the front wall is sprayed from the spray mechanism 50. An opening 41 for discharging the mist-like liquid to the outside is formed.
　また、上部カバー４０の内側には、制御部７０を構成する制御基板と、周囲の照度を検出するための照度センサ１３が取り付けられる。照度センサ１３は制御部７０に電気的に接続されている。上部カバー４０の上部壁の後方寄りには、照度センサ１３が臨む照度センサ窓４２が形成されている。 Further, inside the upper cover 40, a control board constituting the control unit 70 and an illuminance sensor 13 for detecting the ambient illuminance are attached. The illuminance sensor 13 is electrically connected to the control unit 70. An illuminance sensor window 42 facing the illuminance sensor 13 is formed near the rear of the upper wall of the upper cover 40.
　次に、本実施形態の主要部をなす噴霧機構５０について詳述する。噴霧機構５０は、エアノズル５１、液体ノズル５５及び台座部５７を有して構成される。エアノズル５１及び液体ノズル５５は積層配設され、両者が共に台座部５７に支持されている（図３～図５参照）。 Next, the spray mechanism 50, which forms the main part of the present embodiment, will be described in detail. The spray mechanism 50 includes an air nozzle 51, a liquid nozzle 55, and a pedestal portion 57. The air nozzle 51 and the liquid nozzle 55 are laminated and arranged, and both are supported by the pedestal portion 57 (see FIGS. 3 to 5).
　まず、エアノズル５１は、内部にエア流路５１０が形成され、先端がエア吐出口５１１、後端がエア導入口５１２となっている（図６（ｃ）参照）。エア流路５１０は、エア導入口５１２からエア吐出口５１１まで直線状に形成されている。また、図３に示したように、エア導入口５１２にはエア供給チューブ５２の一端が接続され、エア供給チューブ５２はその他端がエア供給源であるコンプレッサー５４に接続されている。コンプレッサー５４は、電池ボックス２３に取り囲まれた範囲の背部カバー２０寄りに配設されていると共に、制御部７０に電気的に接続され、制御部７０の制御信号を受けて駆動し、エア供給チューブ５２を介してエアノズル５１にエア（圧縮空気）を供給する。 First, the air nozzle 51 has an air flow path 510 formed inside, and the front end is an air discharge port 511 and the rear end is an air introduction port 512 (see FIG. 6 (c)). The air flow path 510 is formed linearly from the air introduction port 512 to the air discharge port 511. Further, as shown in FIG. 3, one end of the air supply tube 52 is connected to the air introduction port 512, and the other end of the air supply tube 52 is connected to the compressor 54 which is an air supply source. The compressor 54 is arranged near the back cover 20 in a range surrounded by the battery box 23, is electrically connected to the control unit 70, is driven by receiving a control signal of the control unit 70, and is an air supply tube. Air (compressed air) is supplied to the air nozzle 51 via the 52.
　エアノズル５１は、より詳細には、図６（ａ），（ｂ）に示したように、略直方体に形成された直方体部５１ａと、直方体部５１ａから後方に突出する接続筒部５１ｂを有している。直方体部５１ａの先端面の幅方向中心に、好ましくは直径１ｍｍ以下のエア吐出口５１１となる細孔が形成され、接続筒部５１ｂの突出端が直径約１～４ｍｍのエア導入口５１２となっている。エア流路５１０は、図６（ｃ）の断面図に示したように、エア導入口５１２からエア吐出口５１１まで直線状に貫通形成され、細孔となっているエア吐出口５１１の手前付近はテーパ状になって徐々に絞られ、エア吐出口５１１から導入されるエアはテーパ状になっている部分で流速が増し、勢いよく噴出する。 More specifically, as shown in FIGS. 6A and 6B, the air nozzle 51 has a rectangular parallelepiped portion 51a formed in a substantially rectangular parallelepiped, and a connecting tubular portion 51b protruding rearward from the rectangular parallelepiped portion 51a. ing. A pore serving as an air discharge port 511 having a diameter of 1 mm or less is preferably formed at the center of the tip surface of the rectangular parallelepiped portion 51a in the width direction, and the protruding end of the connecting cylinder portion 51b becomes an air introduction port 512 having a diameter of about 1 to 4 mm. ing. As shown in the cross-sectional view of FIG. 6C, the air flow path 510 is formed to penetrate linearly from the air introduction port 512 to the air discharge port 511 and has pores in the vicinity of the front side of the air discharge port 511. Is tapered and gradually throttled, and the air introduced from the air discharge port 511 increases in flow velocity at the tapered portion and is ejected vigorously.
　液体ノズル５５は、図７（ａ）～（ｃ）に示したように、導入口側部位５５１と吐出口側部位５５２とを有する。導入口側部位５５１は、略直方体状に形成され、その前方側に吐出口側部位５５２が位置するように一体成形されている。導入口側部位５５１は後方に突出する接続筒部５５１ａを有している。接続筒部５５１ａの端部が直径約１～４ｍｍの液体導入口５５１１となっており、この液体導入口５５１１から吐出口側部位５５２方向に向かって、導入口側流路５５１０が直線状に形成されている。接続筒部５５１ａには、液体容器１２内の液体を液体導入口５５１１から導入口側流路５５１０内に供給するための液体供給チューブ５６が接続される。なお、液体供給チューブ５６及び液体容器１２の詳細は、台座部５７の説明と共に後述する。 As shown in FIGS. 7A to 7C, the liquid nozzle 55 has an introduction port side portion 551 and a discharge port side portion 552. The introduction port side portion 551 is formed in a substantially rectangular parallelepiped shape, and is integrally molded so that the discharge port side portion 552 is located on the front side thereof. The introduction port side portion 551 has a connecting cylinder portion 551a that projects rearward. The end of the connection cylinder portion 551a is a liquid introduction port 5511 having a diameter of about 1 to 4 mm, and the introduction port side flow path 5510 is formed linearly from the liquid introduction port 5511 toward the discharge port side portion 552. Has been done. A liquid supply tube 56 for supplying the liquid in the liquid container 12 from the liquid introduction port 5511 into the introduction port side flow path 5510 is connected to the connection cylinder portion 551a. The details of the liquid supply tube 56 and the liquid container 12 will be described later together with the description of the pedestal portion 57.
　吐出口側部位５５２は、上記のように導入口側部位５５１の前方に位置しているが、液体吐出口５５２１が形成されている先端部が、略直方体の導入口側部位５５１の周壁部５５１５におけるエアノズル５１との対向面５５１５ａよりも外方に突出している。そのため、液体ノズル５５は、導入口側部位５５１と吐出口側部位５５２をあわせた全体として、側面視で略Ｌ字状に形成されている。 The discharge port side portion 552 is located in front of the introduction port side portion 551 as described above, but the tip portion on which the liquid discharge port 5521 is formed is the peripheral wall portion 5515 of the introduction port side portion 551 of a substantially rectangular parallelepiped. It protrudes outward from the surface facing the air nozzle 51 in 5515a. Therefore, the liquid nozzle 55 is formed in a substantially L shape in a side view as a whole including the introduction port side portion 551 and the discharge port side portion 552.
　吐出口側部位５５２の内部には、図７（ｃ）に示したように、導入口側流路５５１０に対して直交する方向に吐出口側流路５５２０が形成されている。吐出口側部位５５２の背面（導入口側部位５５１の上記対向面５５１５ａとは反対側に位置する面）５５２ａから液体吐出口５５２１に至るまで貫通形成されており、導入口側流路５５１０の先端が吐出口側流路５５２０の側面に中途で連通している。液体吐出口５５２１は、好ましくは直径約１ｍｍ以下の細孔に形成されており、吐出口側流路５５２０は、液体吐出口５５２１の手前においてテーパ状に絞られ、液体の流速が増す構造になっている。吐出口側部位５５２の背面５５２ａに臨む吐出口側流路５５２０の背面側開口端５５２２には、キャップ部材５５２３が装着されて閉塞される。これにより、導入口側流路５５１０及び吐出口側流路５５２０は、略９０度で交差する略Ｌ字状の一つの流路となって、液体導入口５５１１から液体吐出口５５２１までを連通する。 As shown in FIG. 7C, a discharge port side flow path 5520 is formed inside the discharge port side portion 552 in a direction orthogonal to the introduction port side flow path 5510. It is formed to penetrate from the back surface of the discharge port side portion 552 (the surface of the introduction port side portion 551 opposite to the facing surface 5515a) 552a to the liquid discharge port 5521, and the tip of the inlet side flow path 5510. Communicates halfway with the side surface of the discharge port side flow path 5520. The liquid discharge port 5521 is preferably formed in pores having a diameter of about 1 mm or less, and the discharge port side flow path 5520 is tapered in front of the liquid discharge port 5521 to increase the flow velocity of the liquid. ing. A cap member 5523 is attached to the back opening end 5522 of the discharge port side flow path 5520 facing the back surface 552a of the discharge port side portion 552 to be closed. As a result, the introduction port side flow path 5510 and the discharge port side flow path 5520 become one substantially L-shaped flow path that intersects at approximately 90 degrees, and communicates from the liquid introduction port 5511 to the liquid discharge port 5521. ..
　ここで、エアノズル５１と液体ノズル５５は、上記のように積層して配設されるが、それぞれにノズル用係合部が設けられており、両者を係合させることで一体となる。すなわち、エアノズル５１には、図６（ｂ），（ｃ）に示したように、周壁部５１５のうち、液体ノズル５５との対向面５１５ａには溝状に形成された係合用溝部５１６が設けられ、液体ノズル５５には、図７（ａ）～（ｃ）に示したように、導入口側部位５５の周壁部５５１５の対向面５５１５ａに、エアノズル５１の対向面５１５ａ方向に突出し、係合用溝部５１６に係合する係合用突起５５１６が設けられている。これらの係合用溝部５１６及び係合用突起５５１６がそれぞれノズル用係合部を構成する。 Here, the air nozzle 51 and the liquid nozzle 55 are arranged in a laminated manner as described above, but each is provided with a nozzle engaging portion, and the air nozzle 51 and the liquid nozzle 55 are integrated by engaging them. That is, as shown in FIGS. 6 (b) and 6 (c), the air nozzle 51 is provided with an engaging groove portion 516 formed in a groove shape on the surface 515a facing the liquid nozzle 55 among the peripheral wall portions 515. As shown in FIGS. 7A to 7C, the liquid nozzle 55 projects from the facing surface 5515a of the peripheral wall portion 5515 of the introduction port side portion 55 in the direction of the facing surface 515a of the air nozzle 51 for engagement. An engaging protrusion 5516 that engages with the groove 516 is provided. These engaging groove portions 516 and engaging protrusions 5516 each form a nozzle engaging portion.
　エアノズル５１と、液体ノズル５５の導入口側部位５５１とは、いずれも略直方体に形成され、対向面５１５ａ，５５１５ａ同士が平坦面に形成されている。従って、係合用溝部５１６及び係合用突起５５１６を係合させると、エアノズル５１に直線状に形成されたエア流路５１０と導入側部位５５１に形成された導入口側流路５５１０は略平行な位置関係で配置され、各接続筒部５１ｂ，５５１ａも略平行に延びることになる（図５参照）。 Both the air nozzle 51 and the introduction port side portion 551 of the liquid nozzle 55 are formed in a substantially rectangular parallelepiped shape, and the facing surfaces 515a and 5515a are formed on a flat surface. Therefore, when the engaging groove portion 516 and the engaging protrusion 5516 are engaged, the air flow path 510 formed linearly in the air nozzle 51 and the introduction port side flow path 5510 formed in the introduction side portion 551 are located at substantially parallel positions. Arranged in a relationship, the connecting cylinders 51b and 551a also extend substantially in parallel (see FIG. 5).
　一方、吐出口側部位５５２は、上記のように、導入口側部位５５１の前方に位置し、液体吐出口５５２１が形成されている先端部が、略直方体の導入口側部位５５１の対向面５５１５ａよりも外方に突出している。このため、エアノズル５１の係合用溝部５１６及び液体ノズル５５の導入口側部位５５１の係合用突起５５１６を係合させた状態では、液体吐出口５５２１がエアノズル５１のエア吐出口５１１のすぐ横に近接した位置となる（図４及び図５参照）。なお、両者の離間距離は、できるだけ近いことが好ましく、コンプレッサー５４の能力、液体吐出口５５２１の直径等にもよるが、液体吐出口５５２１の中心に対して略直交する方向に、エア吐出口５１１の端面が３ｍｍ以下であることが好ましく、２ｍｍ以下であることがより好ましく、１ｍｍ以下であるこがさらに好ましい。これにより、エアノズル５１のエア吐出口５１１から吹き出されるエアは、液体吐出口５５２１を直径方向に横切り、液体を吹き飛ばしてミスト化し拡散させる。 On the other hand, the discharge port side portion 552 is located in front of the introduction port side portion 551 as described above, and the tip portion on which the liquid discharge port 5521 is formed is the facing surface 5515a of the introduction port side portion 551 of a substantially rectangular parallelepiped. It protrudes outward. Therefore, in a state where the engaging groove 516 of the air nozzle 51 and the engaging protrusion 5516 of the introduction port side portion 551 of the liquid nozzle 55 are engaged, the liquid discharge port 5521 is close to the air discharge port 511 of the air nozzle 51. (See FIGS. 4 and 5). The distance between the two is preferably as close as possible, and although it depends on the capacity of the compressor 54, the diameter of the liquid discharge port 5521, and the like, the air discharge port 511 is oriented substantially orthogonal to the center of the liquid discharge port 5521. The end face of the is preferably 3 mm or less, more preferably 2 mm or less, and further preferably 1 mm or less. As a result, the air blown out from the air discharge port 511 of the air nozzle 51 crosses the liquid discharge port 5521 in the diameter direction, blows off the liquid, becomes mist, and diffuses.
　なお、本実施形態のエアノズル５１及び液体ノズル５５は、ノズル用係合部である係合用溝部５１６及び係合用突起５５１６を係合させると、このような位置関係となるように、エアノズル５１の軸方向に沿った長さ、液体ノズル５５の導入口側部位５５１の軸方向に沿った長さ及び吐出口側部位５５２の対向面５５１５ａからの突出長さ等の大きさ、係合用溝部５１６及び係合用突起５５１６の形成位置等が調整されている。 The air nozzle 51 and the liquid nozzle 55 of the present embodiment have a shaft of the air nozzle 51 so as to have such a positional relationship when the engaging groove portion 516 and the engaging protrusion 5516, which are the engaging portions for the nozzles, are engaged with each other. The length along the direction, the length along the axial direction of the introduction port side portion 551 of the liquid nozzle 55, the size such as the protrusion length of the discharge port side portion 552 from the facing surface 5515a, the engaging groove portion 516 and the engagement. The formation position of the joint protrusion 5516 is adjusted.
　ケース１０内において、容器支持棚２２に支持される液体容器１２と上部カバー４０との間には、背部カバー２０から前方に突出する台座部取り付けフレーム２４が設けられており、この台座部取り付けフレーム２４に台座部５７が取り付けられる（図３及び図４参照）。台座部５７は、図８に示したように、平面視で略長方形の底面部５７１と、該底面部５７１の後端縁から上方に立ち上がる背面部５７２を有していると共に、両側縁のほぼ中央であって、背面部５７２から前端縁方向に所定間隔をおいて延びる一対の側板部５７３，５７４が設けられている。側板部５７３，５７４の上縁部５７３ａ，５７４ａは、後端縁から前端縁に向かって平坦に延びている一方、中途位置から前端縁に至るまで徐々に高くなる斜面部５７５となっている。なお、台座部５７は、斜面部５７５が、上部カバー４０の開口部４１方向に向かって徐々に高くなるように台座部取り付けフレーム２４に取り付けられる。 In the case 10, a pedestal mounting frame 24 projecting forward from the back cover 20 is provided between the liquid container 12 supported by the container support shelf 22 and the upper cover 40, and the pedestal mounting frame 24 is provided. A pedestal portion 57 is attached to 24 (see FIGS. 3 and 4). As shown in FIG. 8, the pedestal portion 57 has a bottom surface portion 571 that is substantially rectangular in a plan view, and a back surface portion 572 that rises upward from the rear end edge of the bottom surface portion 571, and has substantially both side edges. A pair of side plate portions 573 and 574 extending from the back surface portion 572 in the front end edge direction at predetermined intervals are provided at the center. The upper edge portions 573a and 574a of the side plate portions 573 and 574 extend flatly from the rear end edge toward the front end edge, while forming a slope portion 575 that gradually rises from the middle position to the front end edge. The pedestal portion 57 is attached to the pedestal portion mounting frame 24 so that the slope portion 575 gradually rises toward the opening 41 of the upper cover 40.
　斜面部５７５には、ノズル取り付け部５７６が設けられている。ノズル取り付け部５７６は、所定厚さの板状に形成され、側縁部から横方向に延びるスリット５７６ａが形成されている。このスリット５７６ａは、下面側が幅広で、上面側の幅の狭い形状に形成されている。 A nozzle mounting portion 576 is provided on the slope portion 575. The nozzle mounting portion 576 is formed in a plate shape having a predetermined thickness, and a slit 576a extending in the lateral direction from the side edge portion is formed. The slit 576a is formed in a shape in which the lower surface side is wide and the upper surface side is narrow.
　一方、液体ノズル５５の導入口側部位５５１の背面（上記対向面５５１５ａとは反対側に位置する面）５５１５ｂには、台座部５７方向に突出し、台座用係合部を構成する台座係合用突起５５１７が設けられている（図７（ａ）～（ｃ）参照）。台座係合用突起５５１７は、突出方向先端の幅が広くなっており、台座部５７のノズル取り付け部５７６に形成されたスリット５７６ａに、その側縁部から挿入されて係合可能となっている。よって、ノズル用係合部である係合用溝部５１６及び係合用突起５５１６を相互に係合することにより一体になったエアノズル５１及び液体ノズル５５は、液体ノズル５５の台座係合用突起５５１７を台座５７のノズル取り付け部５７６に係合させることにより、共に台座部５７に支持される（図４及び図５参照）。 On the other hand, on the back surface of the introduction port side portion 551 of the liquid nozzle 55 (the surface located on the side opposite to the facing surface 5515a) 5515b, the pedestal engaging protrusion that protrudes in the pedestal portion 57 direction and constitutes the pedestal engaging portion. 5517 is provided (see FIGS. 7A to 7C). The pedestal engaging protrusion 5517 has a wide tip in the protruding direction, and is inserted into a slit 576a formed in the nozzle mounting portion 576 of the pedestal portion 57 from its side edge portion so that it can be engaged. Therefore, the air nozzle 51 and the liquid nozzle 55, which are integrated by engaging the engaging groove portion 516 and the engaging protrusion 5516, which are the nozzle engaging portions, with each other, have the pedestal engaging protrusion 5517 of the liquid nozzle 55 as the pedestal 57. By engaging with the nozzle mounting portion 576 of the above, both are supported by the pedestal portion 57 (see FIGS. 4 and 5).
　また、ノズル取り付け部５７６は、上記のように前端縁（開口部４１）に向かうほど高くなるように傾斜する傾斜部５７５に設けられている。従って、液体ノズル５５の台座係合用突起５５１７をノズル取り付け部５７６に係合させると、液体ノズル５５及び該液体ノズル５５に係合されたエアノズル５１は、この傾斜部５７５の傾斜角度θ分、斜めに配置されることになる（図４及び図８（ｄ）参照）。 Further, the nozzle mounting portion 576 is provided on the inclined portion 575 that is inclined so as to become higher toward the front end edge (opening 41) as described above. Therefore, when the pedestal engaging protrusion 5517 of the liquid nozzle 55 is engaged with the nozzle mounting portion 576, the liquid nozzle 55 and the air nozzle 51 engaged with the liquid nozzle 55 are oblique by the inclination angle θ of the inclined portion 575. Will be arranged in (see FIGS. 4 and 8 (d)).
　エアノズル５１のエア流路５１０と液体ノズル５５の導入口側流路５５１０は略平行な位置関係であるため、エア流路５１０及び導入口側流路５５１０は、ほぼ同角度、斜め上方に傾斜して配置される。この角度すなわち傾斜部５７５の傾斜角度θがエアにより吹き飛ばされる液体の噴霧角度となる。よって、傾斜部５７５の傾斜角度θは水平に対して２０度～７０度とすることが好ましく、３０度～６０度の範囲とすることがより好ましい。 Since the air flow path 510 of the air nozzle 51 and the introduction port side flow path 5510 of the liquid nozzle 55 are in a substantially parallel positional relationship, the air flow path 510 and the introduction port side flow path 5510 are inclined diagonally upward at substantially the same angle. Is placed. This angle, that is, the inclination angle θ of the inclined portion 575 is the spray angle of the liquid blown off by the air. Therefore, the inclination angle θ of the inclined portion 575 is preferably 20 degrees to 70 degrees with respect to the horizontal, and more preferably 30 degrees to 60 degrees.
　ここで、エアノズル５１のエア吐出口５１１から噴出されるエアによって、液体ノズル５５の液体吐出口５５２１から吐出される液体が開口部４１の外方に向かって吹き飛ばされるため、隣接配置されるエア吐出口５１１及び液体吐出口５５２１は、上部カバー４０に形成された開口部４１に臨む位置となる必要がある。この際、エアノズル５１及び液体ノズル５５は、台座部５７に取り付けられるため、台座係合用突起５５１７、ノズル取り付け部５７６及び斜面部５７５のサイズや形成位置、あるいは、斜面部５７５の傾斜角度等によって位置決めされる。よって、これらのサイズ等を適正に調整することで、エア吐出口５１１及び液体吐出口５５２１か開口部４１に臨む位置となる。 Here, the air ejected from the air discharge port 511 of the air nozzle 51 blows the liquid discharged from the liquid discharge port 5521 of the liquid nozzle 55 toward the outside of the opening 41, so that the air is discharged adjacently. The outlet 511 and the liquid discharge port 5521 need to be positioned so as to face the opening 41 formed in the upper cover 40. At this time, since the air nozzle 51 and the liquid nozzle 55 are attached to the pedestal portion 57, they are positioned according to the size and formation position of the pedestal engaging protrusion 5517, the nozzle attachment portion 576 and the slope portion 575, the inclination angle of the slope portion 575, and the like. Will be done. Therefore, by appropriately adjusting these sizes and the like, the position faces the air discharge port 511 and the liquid discharge port 5521 or the opening 41.
　従って、台座部取り付けフレーム２４に台座部５７を取り付けた状態で、エアノズル５１及び液体ノズル５５を組み付ければ、エア吐出口５１１及び液体吐出口５５２１か適正位置となるように、高い寸法精度を確保するため、エアノズル５１、液体ノズル５５及び台座部５７の３つの部材はそれぞれ射出成形等による合成樹脂の成形品とすることが好ましい。 Therefore, if the air nozzle 51 and the liquid nozzle 55 are assembled with the pedestal portion 57 attached to the pedestal portion mounting frame 24, high dimensional accuracy is ensured so that the air discharge port 511 and the liquid discharge port 5521 are in the proper positions. Therefore, it is preferable that the three members of the air nozzle 51, the liquid nozzle 55, and the pedestal portion 57 are each made of a synthetic resin by injection molding or the like.
　エア吐出口５１１及び液体吐出口５５２１は、開口部４１に臨む位置といっても、開口部４１よりも内側に位置すると、ケース１０内面に付着する液体量が多くなる。従って、開口部４１にできるだけ近い位置に設けることが好ましく、図４に示したように、開口部４１を通過するケース１０の内表面に沿った内側仮想線と同じかそれよりも外方に位置するように設けることがより好ましい。但し、開口部４１よりも外方に突出していると、人の手等が接触したり、あるいは、外観に影響がでたりするため、開口部４１よりも外方に突出していないことが好ましい。 Even if the air discharge port 511 and the liquid discharge port 5521 are positioned facing the opening 41, if they are located inside the opening 41, the amount of liquid adhering to the inner surface of the case 10 increases. Therefore, it is preferable to provide the position as close as possible to the opening 41, and as shown in FIG. 4, the position is the same as or outside the inner virtual line along the inner surface of the case 10 passing through the opening 41. It is more preferable to provide the above. However, if it protrudes outward from the opening 41, it may come into contact with a human hand or the like, or the appearance may be affected. Therefore, it is preferable that the protrusion does not protrude outward from the opening 41.
　従って、図４に示したように、液体ノズル５５の液体吐出口５５２１は、開口部４１を通過するケース１０の内表面に沿った内側仮想線Ｐと、開口部４１を通過するケース１０の外表面に沿った外側仮想線Ｑとに挟まれた開口部４１を形成する周縁部の厚みｔの範囲内に位置するように設けられることがさらに好ましい。これにより、液体ノズル５５の液体吐出口５５２１は開口部４１の内方には位置しないため、エアによって吹き飛ばされる液体が、ケース１０の内面に付着することはほとんどなくなる。 Therefore, as shown in FIG. 4, the liquid discharge port 5521 of the liquid nozzle 55 has an inner virtual line P along the inner surface of the case 10 passing through the opening 41 and an outer side of the case 10 passing through the opening 41. It is more preferably provided so as to be located within the thickness t of the peripheral edge portion forming the opening 41 sandwiched between the outer virtual line Q along the surface. As a result, since the liquid discharge port 5521 of the liquid nozzle 55 is not located inside the opening 41, the liquid blown off by the air hardly adheres to the inner surface of the case 10.
　一方、エアノズル５１のエア吐出口５５１も、図４に示したように、開口部４１を通過するケース１０の内表面に沿った内側仮想線Ｐと、開口部４１を通過するケース１０の外表面に沿った外側仮想線Ｑとに挟まれた開口部４１を形成する周縁部の厚みｔの範囲内に位置するように設けられることがより好ましい。エアノズル５１のエア吐出口５５１は、液体吐出口５５２１から吐出される液体を開口部４１の外方に吹き飛ばすことができれば必ずしもこの位置に設けられることに限定されるものではないが、液体吐出口５５２１付近を負圧にして液体を吸い上げて吹き飛ばすためには、液体吐出口５５２１に近接していることが好ましく、上記の開口部４１を形成する厚みｔの範囲に設けることが適している。 On the other hand, as shown in FIG. 4, the air discharge port 551 of the air nozzle 51 also has an inner virtual line P along the inner surface of the case 10 passing through the opening 41 and an outer surface of the case 10 passing through the opening 41. More preferably, it is provided so as to be located within the thickness t of the peripheral edge portion forming the opening 41 sandwiched between the outer virtual line Q along the line. The air discharge port 551 of the air nozzle 51 is not necessarily limited to being provided at this position as long as the liquid discharged from the liquid discharge port 5521 can be blown to the outside of the opening 41, but the liquid discharge port 5521 In order to suck up and blow off the liquid with a negative pressure in the vicinity, it is preferable that the liquid is close to the liquid discharge port 5521, and it is suitable to provide the liquid in the range of the thickness t forming the opening 41.
　また、本実施形態においては、ケース１０の開口部４１が、上記のように上部カバー４０に形成されており、開口部４１を通過する外側仮想線Ｑは、湾曲している。従って、液体ノズル５５における吐出口側部位５５２の吐出口側流路５５２１と略平行な外側面５５２ｂも、外側仮想線Ｑに概略沿うように湾曲していることが好ましい（図４及び図７（ａ）～（ｃ）参照）。これにより、外側面５５２ｂが開口部４１の外方に突出せずに、液体吐出口５５２１を上記した所定の位置にセットすることができる。 Further, in the present embodiment, the opening 41 of the case 10 is formed in the upper cover 40 as described above, and the outer virtual line Q passing through the opening 41 is curved. Therefore, it is preferable that the outer surface 552b of the liquid nozzle 55, which is substantially parallel to the discharge port side flow path 5521 of the discharge port side portion 552, is also curved so as to roughly follow the outer virtual line Q (FIGS. 4 and 7 (FIGS. 4 and 7). a)-(c)). As a result, the liquid discharge port 5521 can be set at the above-mentioned predetermined position without the outer surface 552b projecting outward from the opening 41.
　台座部５７は、図８（ｂ），（ｃ）に示したように、底面部５７１における一対の側板部５７３，５７４間に位置する部位から、背面部５７２の中途位置に至るまでの範囲に亘り、チューブ通過スリット５７１ａが形成されている。このチューブ通過スリット５７１ａは、液体ノズル５５の接続筒部５５１ａの延長線上に開口を有する大きさで形成されている。これにより、接続筒部５５１ａと液体容器１２とを結ぶ液体供給チューブ５６がチューブ通過スリット５７１ａを介して配設される。 As shown in FIGS. 8B and 8C, the pedestal portion 57 extends from a portion of the bottom surface portion 571 between the pair of side plate portions 573 and 574 to an intermediate position of the back surface portion 572. A tube passage slit 571a is formed over the entire surface. The tube passage slit 571a is formed in a size having an opening on an extension line of the connecting cylinder portion 551a of the liquid nozzle 55. As a result, the liquid supply tube 56 connecting the connecting cylinder portion 551a and the liquid container 12 is arranged via the tube passage slit 571a.
　ここで、本実施形態で使用した液体容器１２は、全体として略直方体で、上部に筒状突出部１２ａを有し、その筒状突出部１２ａの略中央部に液体出口１２ｂが設けられている。液体容器１２内には、下端が液体中に浸漬された容器内チューブ１２ｃが配設されており、容器内チューブ１２ｃの上端が液体出口１２ｂに連通するように接続されている。一方、上記台座部５７を支持する台座部取り付けフレーム２４の若干下方に、背部カバー２０から前方に突出し、容器支持棚２２に液体容器１２を載置した状態で、液体出口１２ｂの上方に至る範囲まで延びる容器接続部取り付けフレーム２５が設けられている。容器接続部取り付けフレーム２５における、上記液体容器１２の液体出口１２ｂの上方に相当する部位に、容器接続部５８が取り付けられている。 Here, the liquid container 12 used in the present embodiment is a substantially rectangular parallelepiped as a whole, has a tubular protrusion 12a at the upper portion, and is provided with a liquid outlet 12b at a substantially central portion of the tubular protrusion 12a. .. Inside the liquid container 12, an in-container tube 12c whose lower end is immersed in the liquid is disposed, and the upper end of the in-container tube 12c is connected so as to communicate with the liquid outlet 12b. On the other hand, a range extending forward from the back cover 20 to slightly below the pedestal mounting frame 24 that supports the pedestal 57, and above the liquid outlet 12b with the liquid container 12 placed on the container support shelf 22. A container connecting portion mounting frame 25 extending to is provided. The container connection portion 58 is attached to a portion of the container connection portion attachment frame 25 corresponding to the upper part of the liquid outlet 12b of the liquid container 12.
　容器接続部５８は、液体容器１２の筒状突出部１２ａ内に嵌合可能な所定厚さの略円板状に形成され、上下に貫通する液体流通孔５８ａが設けられている。液体容器１２を容器支持棚２２上に載置すると、弾性部材２１ａにより上部棚部２１に対して上方に付勢され、液体容器１２の筒状突出部１２ａが容器接続部５８に嵌合する。それにより、液体容器１２の液体出口１２ｂが、容器接続部５８の液体流通孔５８ａの下端側に連通する。 The container connecting portion 58 is formed in a substantially disk shape having a predetermined thickness that can be fitted in the tubular protruding portion 12a of the liquid container 12, and is provided with a liquid flow hole 58a penetrating vertically. When the liquid container 12 is placed on the container support shelf 22, the elastic member 21a urges the liquid container 12 upward with respect to the upper shelf portion 21, and the tubular protruding portion 12a of the liquid container 12 fits into the container connecting portion 58. As a result, the liquid outlet 12b of the liquid container 12 communicates with the lower end side of the liquid flow hole 58a of the container connecting portion 58.
　液体供給チューブ５６は、第１チューブ５６１と第２チューブ５６２とを組み合わせて構成される。第１チューブ５６１の一端５６１ａは、上記の容器接続部５８の液体流通孔５８ａの上端側に接続されている。第１チューブ５６１は、一端５６１ａから上方に延び、台座部５７のチューブ通過スリット５７１ａを通過すると共に、中途で若干曲がって、液体ノズル５５の接続筒部５５１ａ方向に延びる略Ｌ字状（好ましくは、２辺の交差角度が鈍角である略Ｌ字状）に形成されている。これにより、第１チューブ５６１の先端開口部５６１ｂは、接続筒部５５１ａにほぼ向かって開口する向きとなっている。 The liquid supply tube 56 is configured by combining the first tube 561 and the second tube 562. One end 561a of the first tube 561 is connected to the upper end side of the liquid flow hole 58a of the container connecting portion 58. The first tube 561 extends upward from one end 561a, passes through the tube passage slit 571a of the pedestal portion 57, bends slightly in the middle, and extends in the direction of the connecting cylinder portion 551a of the liquid nozzle 55 (preferably in a substantially L shape). , The intersection angle of the two sides is an obtuse angle (approximately L-shape). As a result, the tip opening 561b of the first tube 561 is oriented so as to open substantially toward the connecting cylinder 551a.
　第２チューブ５６２は、第１チューブ５６１の先端開口部５６１ｂと液体ノズル５５の接続筒部５５１ａとを接続する。第１チューブ５６１の先端開口部５６１ｂが、接続筒部５５１ａにほぼ向かって開口する向きとなっているため、両者を接続する第２チューブ５６２はほぼ真っ直ぐに配設される。 The second tube 562 connects the tip opening 561b of the first tube 561 and the connecting cylinder portion 551a of the liquid nozzle 55. Since the tip opening 561b of the first tube 561 is oriented so as to open substantially toward the connecting cylinder portion 551a, the second tube 562 connecting the two is arranged substantially straight.
　なお、第１チューブ５６１は、上記のように、チューブ通過スリット５７１ａを通過した後曲がる部分を有しているが、その曲がっている部分でチューブの潰れが生じないように、金属や硬質のプラスチックなどのパイプ材からなることが好ましい。 As described above, the first tube 561 has a portion that bends after passing through the tube passage slit 571a, but metal or hard plastic is used so that the tube is not crushed at the bent portion. It is preferable that it is made of a pipe material such as.
　本実施形態の液体供給チューブ５６は、上記のようなチューブ通過スリット５７１ａを通過する第１チューブ５６１と、第１チューブと液体ノズル５５との間でほぼ真っ直ぐ配設される第２チューブ５６２とから構成されるため、図４に示したように、中途で極端に屈曲する部位が形成されることなくキンクによる噴霧不良を抑制できる。 The liquid supply tube 56 of the present embodiment is composed of a first tube 561 that passes through the tube passage slit 571a as described above, and a second tube 562 that is arranged substantially straight between the first tube and the liquid nozzle 55. Therefore, as shown in FIG. 4, it is possible to suppress spray failure due to kink without forming a portion that is extremely bent in the middle.
　次に、噴霧機構５０の動作について説明する。
　エアノズル５１には、コンプレッサー５４の駆動により、エア（圧縮空気）が送り込まれ、水平方向に対して斜め上にエア吐出口５１１からエア（圧縮空気）が噴射される。なお、本実施形態のように照度センサ１３を設けている場合には、所定の明るさになったことを照度センサ１３が検知すると、制御部７０から制御信号が送られてコンプレッサー５４が駆動する。 Next, the operation of the spray mechanism 50 will be described.
Air (compressed air) is sent to the air nozzle 51 by driving the compressor 54, and air (compressed air) is injected from the air discharge port 511 diagonally upward with respect to the horizontal direction. When the illuminance sensor 13 is provided as in the present embodiment, when the illuminance sensor 13 detects that the brightness has reached a predetermined level, a control signal is sent from the control unit 70 to drive the compressor 54. ..
　エア（圧縮空気）が噴射されると、液体ノズル５５の液体吐出口５５２１が上記のようにエアノズル５１のエア吐出口５１１に近接しているため、液体ノズル５５の液体吐出口５５２１付近の外部を、液体の吐出方向に対して略直交するように、すなわち横切るように該エアが通過する。それにより、液体ノズル５５の液体吐出口５５２１付近が負圧になり、液体容器１２内の芳香剤や消臭剤等の液体が、液体供給チューブ５６を介して吸引され、液体ノズル５５の先端の液体吐出口５５２１から吐出される。液体は、液体ノズル５５から外部に吐出されると同時に、液体吐出口５５２１の直前を通過するエアノズル５１から噴射されるエアが衝突する。すると、液体は数十μｍ以下乃至数μｍ以下に微細化されてミストＭとなり、エアノズル５１から噴射されるエア圧力に応じて、上部カバー４０の開口部４１を通過して外部へ吹き飛ばされて拡散される（図４参照）。 When air (compressed air) is injected, the liquid discharge port 5521 of the liquid nozzle 55 is close to the air discharge port 511 of the air nozzle 51 as described above, so that the outside of the vicinity of the liquid discharge port 5521 of the liquid nozzle 55 is exposed. , The air passes so as to be substantially orthogonal to, that is, across the discharge direction of the liquid. As a result, the vicinity of the liquid discharge port 5521 of the liquid nozzle 55 becomes a negative pressure, and liquids such as fragrances and deodorants in the liquid container 12 are sucked through the liquid supply tube 56, and the tip of the liquid nozzle 55 It is discharged from the liquid discharge port 5521. The liquid is discharged to the outside from the liquid nozzle 55, and at the same time, the air injected from the air nozzle 51 passing immediately before the liquid discharge port 5521 collides with the liquid. Then, the liquid is miniaturized to several tens of μm or less to several μm or less to become mist M, and is blown to the outside through the opening 41 of the upper cover 40 and diffused according to the air pressure injected from the air nozzle 51. (See FIG. 4).
　液体は、上記したように、液体ノズル５５の液体吐出口５５２１付近の外部をエア（圧縮空気）が通過することによって、液体供給チューブ５６を介して液体容器１２内から強制的に吸引されて吹き飛ばされる。このとき、上記のように液体供給チューブ５６に潰れがなく、液体が円滑に噴出されると共に、液体ノズル５５の液体吐出口５５２１の位置が、上記のように開口部４１の厚みｔの範囲に位置しているため、ケース１０の内面に付着する液体量が減り、液体の無駄を抑制できる。また、エアノズル５１、液体ノズル５５及び台座部５７が上記のように合成樹脂の成形品であり、これらを相互に係合させるだけで、液体吐出口５５２１とエア吐出口５１１とを所定の距離で近接させて、開口部４１の厚みｔの範囲という適正な範囲に位置させることができる。その結果、エアノズル及び液体ノズルを金属製のパイプにより成形し、ケース内に別々に配置する従来の構造と比較し、エアノズル５１及び液体ノズル５５のケース１０における適正位置への取り付けが容易で組み立て作業の簡略化を図ることができ、かつ、噴霧される液体のミストＭは、より微細化が促進される。そのため、噴霧した液体のミストＭが、より長時間にわたって空中を漂うことが可能となり、ホテルやレストランなどのトイレのような広い空間において、芳香等の液体効果を全体により均一に行きわたらせることができる。 As described above, the liquid is forcibly sucked from the inside of the liquid container 12 through the liquid supply tube 56 and blown off by the air (compressed air) passing through the outside near the liquid discharge port 5521 of the liquid nozzle 55. Is done. At this time, the liquid supply tube 56 is not crushed as described above, the liquid is smoothly ejected, and the position of the liquid discharge port 5521 of the liquid nozzle 55 is within the range of the thickness t of the opening 41 as described above. Since it is located, the amount of liquid adhering to the inner surface of the case 10 is reduced, and waste of liquid can be suppressed. Further, the air nozzle 51, the liquid nozzle 55, and the pedestal portion 57 are molded products of synthetic resin as described above, and the liquid discharge port 5521 and the air discharge port 511 can be provided at a predetermined distance simply by engaging them with each other. It can be placed close to each other in an appropriate range of the thickness t of the opening 41. As a result, compared with the conventional structure in which the air nozzle and the liquid nozzle are molded by a metal pipe and arranged separately in the case, the air nozzle 51 and the liquid nozzle 55 can be easily attached to the proper position in the case 10 and the assembly work is performed. The mist M of the liquid to be sprayed can be further miniaturized. Therefore, the sprayed liquid mist M can float in the air for a longer period of time, and the liquid effect such as fragrance can be more evenly distributed in a wide space such as a toilet in a hotel or restaurant. it can.
　また、制御部７０では、例えば液体を噴霧する駆動時間をタイマでセットすることによって、所定の時間になると自動的に噴霧する構成とすることもできる。一方、本実施形態の液体噴霧装置１が例えば公衆トイレなどに設置される場合、人が使用しない時間帯は噴霧する必要がない。そこで、上記したように照度センサ１３を設けることによって、所定以上の明るさになった場合のみ、噴霧駆動する構成とすることで液体消費の無駄を省くことができる。 Further, the control unit 70 can be configured to automatically spray the liquid at a predetermined time by setting, for example, a driving time for spraying the liquid with a timer. On the other hand, when the liquid spraying device 1 of the present embodiment is installed in, for example, a public toilet, it is not necessary to spray it during a time when it is not used by a person. Therefore, by providing the illuminance sensor 13 as described above, it is possible to eliminate waste of liquid consumption by adopting a configuration in which the illuminance sensor 13 is spray-driven only when the brightness becomes a predetermined value or higher.
　また、液体容器１２が支持される容器支持棚２２は、上部棚部２１上に弾性部材２１ａを介して配設される。このため、液体容器１２を容器支持棚２２上に載置すれば、弾性部材２１ａによって液体容器１２の液体出口１２ｂが、その上方に位置する容器接続部５８の液体流通孔５８ａに連通される。特許文献２の構造では、液体供給チューブが液体容器の内外に延び、それに液体ノズルを接続する構成であったため、液体容器の交換作業に手間がかかっていた。しかし、本実施形態によれば、容器支持棚２２上の空になった液体容器１２を弾性部材２１ａの弾性力に抗して下方に押し下げて容器接続部５８との嵌合を解除して取り除き、次いで新しい液体容器１２を再び容器支持棚２２上に下方に押しながら載置すれば、弾性部材２１ａの弾性力によって容器接続部５８に接続されるため、交換作業が容易である。 Further, the container support shelf 22 on which the liquid container 12 is supported is arranged on the upper shelf portion 21 via the elastic member 21a. Therefore, when the liquid container 12 is placed on the container support shelf 22, the liquid outlet 12b of the liquid container 12 is communicated with the liquid flow hole 58a of the container connection portion 58 located above the elastic member 21a. In the structure of Patent Document 2, since the liquid supply tube extends inside and outside the liquid container and the liquid nozzle is connected to the liquid supply tube, it takes time and effort to replace the liquid container. However, according to the present embodiment, the empty liquid container 12 on the container support shelf 22 is pushed downward against the elastic force of the elastic member 21a to release the fitting with the container connecting portion 58 and then removed. If the new liquid container 12 is placed on the container support shelf 22 while being pushed downward again, it is connected to the container connecting portion 58 by the elastic force of the elastic member 21a, so that the replacement work is easy.
　なお、上記した説明では、液体は、エアノズル５１から噴き出されるエアの負圧によって吸い上げられて吐出する構成であるが、液体容器１２と液体供給チューブ５６との間にポンプ（図示せず）を設け、このポンプを駆動させて必要量の液体を吸い上げる構成とすることもできる。ポンプの駆動によって所定量の液体が液体ノズル５５の先端の液体吐出口５５２１から強制的に吐出され、その液体に、エアノズル５１から噴射されるエアが衝突する。その後は、上記実施形態と同様に、液体はミスト状に微細化される。コンプレッサー５４の性能、すなわち、エアノズル５１から噴射されるエアの圧力があまり高くない場合等においては、このように、ポンプを利用した構成とすることもできる。 In the above description, the liquid is sucked up by the negative pressure of the air ejected from the air nozzle 51 and discharged, but a pump (not shown) is provided between the liquid container 12 and the liquid supply tube 56. It can also be provided so that the pump is driven to suck up a required amount of liquid. A predetermined amount of liquid is forcibly discharged from the liquid discharge port 5521 at the tip of the liquid nozzle 55 by driving the pump, and the air injected from the air nozzle 51 collides with the liquid. After that, the liquid is miniaturized into a mist as in the above embodiment. When the performance of the compressor 54, that is, when the pressure of the air injected from the air nozzle 51 is not so high, a pump can be used in this way.
