One end of the second pipe portion 28 is watertightly fixed to the upper opening end of the first pipe portion 27 in the container portion 20. Most of the second pipe portion 28 is arranged outside the container portion 20. The liquid supply pipe 4 and the first air supply pipe 6 are housed in the second pipe portion 28. Since the second pipe portion 28 has an inverted U shape, the other end faces downward. The second pipe portion 28 may have an L-shape with the other end facing sideways, an I-shape with the other end facing upward, or the like. That is, the shape of the second pipe portion 28 is not particularly limited. Further, the second pipe portion 28 may have an integral structure with the first pipe portion 27.

図４に示すように、カバー部３０中には、本体部３１が収納保持されている。カバー部３０は、第２管部２８の他端に取り付けられている。カバー部３０には、液供給管４の一端４０と第１空気供給管６の一端６０とが挿通されている。 As shown in FIG. 4, the main body 31 is stored and held in the cover 30. The cover portion 30 is attached to the other end of the second pipe portion 28. One end 40 of the liquid supply pipe 4 and one end 60 of the first air supply pipe 6 are inserted into the cover portion 30.

本体部３１には、液供給管４の一端４０と第１空気供給管６の一端６０とが接続部材を介して接続されている。本体部３１は、図４に示すように、混合室３２と、液連通路３３と、空気連通路３４と、噴射口３５と、を有する。 One end 40 of the liquid supply pipe 4 and one end 60 of the first air supply pipe 6 are connected to the main body 31 via a connecting member. As shown in FIG. 4, the main body 31 has a mixing chamber 32, a liquid communication passage 33, an air communication passage 34, and an injection port 35.

混合室３２は、本体部３１のうち、液供給管４の一端４０および第１空気供給管６の一端６０が接続されている端部に対して反対側の端部に設けられている。液連通路３３は、本体部３１のうち、液供給管４の一端４０と混合室３２との間に設けられていて、液供給管４の一端４０と混合室３２と連通させる。空気連通路３４は、本体部３１のうち、第１空気供給管６の一端６０と混合室３２との間に設けられていて、第１空気供給管６の一端６０と混合室３２と連通させる。これにより、混合室３２は、液供給管４および液連通路３３を経て送られた液１００と、第１空気供給管６および空気連通路３４を経て送られた空気１０４とを混合する。噴射口３５は、本体部３１のうち、液供給管４の一端４０および第１空気供給管６の一端６０が接続されている端部に対して反対側の端部に設けられている。また、噴射口３５は、混合室３２のうち、液連通路３３および空気連通路３４に対して反対側において連通している。これにより、噴射口３５は、混合室３２に送られかつ混合された液１００と空気１０４とを霧１０３として外部に噴射させる。 The mixing chamber 32 is provided at an end of the main body 31 opposite to the end to which one end 40 of the liquid supply pipe 4 and one end 60 of the first air supply pipe 6 are connected. The liquid communication passage 33 is provided between one end 40 of the liquid supply pipe 4 and the mixing chamber 32 in the main body 31, and communicates the one end 40 of the liquid supply pipe 4 with the mixing chamber 32. The air communication passage 34 is provided between one end 60 of the first air supply pipe 6 and the mixing chamber 32 in the main body 31, and communicates with the one end 60 of the first air supply pipe 6 and the mixing chamber 32. .. As a result, the mixing chamber 32 mixes the liquid 100 sent through the liquid supply pipe 4 and the liquid communication passage 33 with the air 104 sent through the first air supply pipe 6 and the air communication passage 34. The injection port 35 is provided at an end of the main body 31 opposite to the end to which one end 40 of the liquid supply pipe 4 and one end 60 of the first air supply pipe 6 are connected. Further, the injection port 35 communicates with the liquid communication passage 33 and the air communication passage 34 on the opposite side of the mixing chamber 32. As a result, the injection port 35 injects the liquid 100 and the air 104 sent to and mixed in the mixing chamber 32 to the outside as mist 103.

混合室３２は、下混合室３２Ｄと、上混合室３２Ｕと、からなる。下混合室３２Ｄは、円錐台形形状をなす。下混合室３２Ｄの噴射口３５側（下側）の断面積（直径）Ｓ１は、下混合室３２Ｄの液連通路３３および空気連通路３４側（上側）の断面積（直径）Ｓ２よりも小さい。すなわち、下混合室３２Ｄは、断面積が液１００および空気１０４の流れ（進む）方向に徐々に小さくなる先細のノズル形状をなす。上混合室３２Ｕは、一部の円筒形状、すなわち、下混合室３２Ｄの上側の円の一部の筒形状をなす。 The mixing chamber 32 includes a lower mixing chamber 32D and an upper mixing chamber 32U. The lower mixing chamber 32D has a conical trapezoidal shape. The cross-sectional area (diameter) S1 of the injection port 35 side (lower side) of the lower mixing chamber 32D is smaller than the cross-sectional area (diameter) S2 of the liquid communication passage 33 and the air communication passage 34 side (upper side) of the lower mixing chamber 32D. .. That is, the lower mixing chamber 32D has a tapered nozzle shape in which the cross-sectional area gradually decreases in the flow (advancing) direction of the liquid 100 and the air 104. The upper mixing chamber 32U has a partial cylindrical shape, that is, a partial cylindrical shape of the upper circle of the lower mixing chamber 32D.

液連通路３３は、円錐台形形状をなす。液連通路３３の下混合室３２Ｄ側の出口３３０の断面積（直径）Ｓ３は、液連通路３３の液供給管４側の入口３３１の断面積（直径）Ｓ４よりも小さい。すなわち、液連通路３３は、下混合室３２Ｄと同様に、断面積が液１００の流れ（進む）方向に徐々に小さくなる先細のノズル形状をなす。 The liquid passage 33 has a conical trapezoidal shape. The cross-sectional area (diameter) S3 of the outlet 330 on the lower mixing chamber 32D side of the liquid-series passage 33 is smaller than the cross-sectional area (diameter) S4 of the inlet 331 on the liquid supply pipe 4 side of the liquid-series passage 33. That is, the liquid passage 33 has a tapered nozzle shape in which the cross-sectional area gradually decreases in the flow (advancing) direction of the liquid 100, similarly to the lower mixing chamber 32D.

空気連通路３４は、円筒形形状をなす。この結果、空気連通路３４の上混合室３２Ｕ側の出口３４０から空気連通路３４の第１空気供給管６側の入口３４１までの断面積（直径）Ｓ５は、一定もしくはほぼ一定である。 The air passage 34 has a cylindrical shape. As a result, the cross-sectional area (diameter) S5 from the outlet 340 on the upper mixing chamber 32U side of the air passage 34 to the inlet 341 on the first air supply pipe 6 side of the air passage 34 is constant or almost constant.

液連通路３３の出口３３０の断面積（直径）Ｓ３は、空気連通路３４の出口３４０の断面積（直径）Ｓ５よりも小さい。この例では、約１：２である。液連通路３３の出口３３０から噴射口３５までの距離Ｈ１は、空気連通路３４の出口３４０から噴射口３５までの距離Ｈ２よりも小さい。この例における本体部３１は、上混合室３２Ｕ、液連通路３３および空気連通路３４を有する部分と、下混合室３２Ｄおよび噴射口３５を有する部分との２部品から構成されている。なお、本体部３１としては、１部品から構成されているものであっても良い。 The cross-sectional area (diameter) S3 of the outlet 330 of the liquid passage 33 is smaller than the cross-sectional area (diameter) S5 of the outlet 340 of the air passage 34. In this example, it is about 1: 2. The distance H1 from the outlet 330 of the liquid passage 33 to the injection port 35 is smaller than the distance H2 from the outlet 340 of the air passage 34 to the injection port 35. The main body 31 in this example is composed of two parts, a portion having an upper mixing chamber 32U, a liquid communication passage 33 and an air communication passage 34, and a portion having a lower mixing chamber 32D and an injection port 35. The main body 31 may be composed of one component.

（液供給管４の説明）
液供給管４は、図１〜図４に示すように、円管からなり、ほぼＳ字形状をなす。すなわち、一端４０側の上端部分４Ｕが逆Ｕ字形状をなす。他端４１側の下端部分４ＤがＵ字形状をなす。上端部分４Ｕから下端部分４Ｄまでの右側部分４Ｒが垂直な直線形状をなす。下端部分４Ｄから他端４１までの左側部分４Ｌが垂直な直線形状をなす。 (Explanation of liquid supply pipe 4)
As shown in FIGS. 1 to 4, the liquid supply pipe 4 is formed of a circular pipe and has a substantially S-shape. That is, the upper end portion 4U on the one end 40 side forms an inverted U shape. The lower end portion 4D on the other end 41 side has a U shape. The right side portion 4R from the upper end portion 4U to the lower end portion 4D forms a vertical linear shape. The left side portion 4L from the lower end portion 4D to the other end 41 forms a vertical linear shape.

液供給管４の一端４０は、噴霧部材３に接続されている。液供給管４のうち、一端４０から上端部分４Ｕを経て右側部分４Ｒまでの部分は、第１管部２７および第２管部２８中に収納されている。液供給管４の下端部分４Ｄは、底部２４中に収納されている。液供給管４の左側部分４Ｌは、そのまま容器部材２の容器部２０中に収納されている。液供給管４の左側部分４Ｌと容器部２０の下面閉塞部とは、水密に保たれている。 One end 40 of the liquid supply pipe 4 is connected to the spray member 3. The portion of the liquid supply pipe 4 from one end 40 through the upper end portion 4U to the right side portion 4R is housed in the first pipe portion 27 and the second pipe portion 28. The lower end portion 4D of the liquid supply pipe 4 is housed in the bottom portion 24. The left side portion 4L of the liquid supply pipe 4 is housed in the container portion 20 of the container member 2 as it is. The left side portion 4L of the liquid supply pipe 4 and the lower surface closing portion of the container portion 20 are kept watertight.

液供給管４の下端部分４Ｄ、右側部分４Ｒおよび左側部分４Ｌは、この例では、中間部分４２とする。このため、この例における液供給管４の中間部分４２のうち左側部分４Ｌの上端が他端４１となる。液供給管４の中間部分４２のうち下端部分４Ｄは、容器部材２の下部分であって、容器部２０の筒部２００に弁部材９を介して接続されている。 The lower end portion 4D, the right side portion 4R, and the left side portion 4L of the liquid supply pipe 4 are referred to as an intermediate portion 42 in this example. Therefore, the upper end of the left side portion 4L of the intermediate portion 42 of the liquid supply pipe 4 in this example is the other end 41. The lower end portion 4D of the intermediate portion 42 of the liquid supply pipe 4 is the lower portion of the container member 2, and is connected to the tubular portion 200 of the container portion 20 via the valve member 9.

液供給管４の中間部分４２は、容器部２０中の液１００を所定量だけ一時的に溜めている。この液１００の所定量は、容器部２０中の液面１０２の高さに応じて変わる。すなわち、容器部２０中の液１００が弁部材９を介して液供給管４の中間部分４２中に入った際に、容器部２０中の液面１０２と液供給管４の右側部分４Ｒおよび左側部分４Ｌ中の液面（図示せず）とは、同一もしくはほぼ同一の水位である。なお、液供給管４の中間部分４２中に溜めている液１００の所定量は、この例では、容器部２０中が液１００で満杯の時に、約２ｍｌである。 The intermediate portion 42 of the liquid supply pipe 4 temporarily stores a predetermined amount of the liquid 100 in the container portion 20. The predetermined amount of the liquid 100 varies depending on the height of the liquid level 102 in the container portion 20. That is, when the liquid 100 in the container portion 20 enters the intermediate portion 42 of the liquid supply pipe 4 via the valve member 9, the liquid level 102 in the container portion 20 and the right side portion 4R and the left side of the liquid supply pipe 4 The liquid level (not shown) in the portion 4L is the same or almost the same water level. In this example, the predetermined amount of the liquid 100 stored in the intermediate portion 42 of the liquid supply pipe 4 is about 2 ml when the container portion 20 is filled with the liquid 100.

液供給管４の一端４０側の少なくとも一部分と他端４１とは、容器部２０中の液面１０２よりも上位に位置する。この少なくとも一部分は、この例では、一端４０から上端部分４Ｕを経て右側部分４Ｒのうち液面１０２に対応する箇所までの部分である。なお、一端４０が液面１０２よりも下位に位置しても良い。液供給管４の一端４０側部分の上端部分４Ｕの断面積（内径）Ｓ６は、液供給管４の中間部分４２の右側部分４Ｒの断面積（内径）Ｓ７よりも小さい。 At least a part of the liquid supply pipe 4 on the one end 40 side and the other end 41 are located above the liquid level 102 in the container portion 20. At least a part of this is, in this example, a part from one end 40 through the upper end portion 4U to the portion of the right side portion 4R corresponding to the liquid level 102. One end 40 may be located below the liquid level 102. The cross-sectional area (inner diameter) S6 of the upper end portion 4U of the one end 40 side portion of the liquid supply pipe 4 is smaller than the cross-sectional area (inner diameter) S7 of the right side portion 4R of the intermediate portion 42 of the liquid supply pipe 4.

（エアポンプ５の説明）
エアポンプ５は、駆動モータなどの駆動部５０と、駆動部５０に機械的に接続されているポンプ部５１と、を備える。ポンプ部５１は、この例では、ダイヤフラムポンプである。エアポンプ５は、駆動部５０の駆動によりポンプ部５１が駆動して、空気１０４を、空気分岐部材８を介して、第１空気供給管６および第２空気供給管７中に、送る。エアポンプ５は、容器部材２の収納部２６中に、収納されている。 (Explanation of air pump 5)
The air pump 5 includes a drive unit 50 such as a drive motor and a pump unit 51 that is mechanically connected to the drive unit 50. The pump unit 51 is a diaphragm pump in this example. In the air pump 5, the pump unit 51 is driven by the drive of the drive unit 50 to send air 104 into the first air supply pipe 6 and the second air supply pipe 7 via the air branch member 8. The air pump 5 is housed in the storage part 26 of the container member 2.

（制御部材１２の説明）
制御部材１２は、エアポンプ５の駆動を制御するものである。制御部材１２は、図１２に示すように、検出器１２０、１２１と、制御部１２２と、を有する。制御部１２２は、電源スイッチ１４および駆動部５０にそれぞれ電気的に接続されている。 (Explanation of control member 12)
The control member 12 controls the drive of the air pump 5. As shown in FIG. 12, the control member 12 includes detectors 120 and 121 and a control unit 122. The control unit 122 is electrically connected to the power switch 14 and the drive unit 50, respectively.

発光部もしくは受光部の検出器１２０は、図９に示すように、噴霧部材３のカバー部３０に設けられている。一方、受光部もしくは発光部の検出器１２１は、図８に示すように、容器部材２の底部２４に設けられている。検出器１２０、１２１は、噴霧部材３に近づいた対象物（この例では、人の手１３）を検出して検出信号を出力する。検出器１２０、１２１は、この例では、透過式の光センサである。光が遮蔽されることにより、手１３を検出する。なお、検出器１２０、１２１としては、手１３を検出するセンサであれば、透過式の光センサ以外のセンサでも良い。 As shown in FIG. 9, the detector 120 of the light emitting unit or the light receiving unit is provided on the cover portion 30 of the spray member 3. On the other hand, the detector 121 of the light receiving unit or the light emitting unit is provided on the bottom 24 of the container member 2 as shown in FIG. The detectors 120 and 121 detect an object (in this example, the human hand 13) approaching the spray member 3 and output a detection signal. The detectors 120, 121 are transmissive photosensors in this example. The hand 13 is detected by blocking the light. The detectors 120 and 121 may be sensors other than the transmission type optical sensor as long as they are sensors that detect the hand 13.

制御部１２２は、底部２４あるいは収納部２６中に収納されている。制御部１２２は、検出器１２０、１２１から出力された検出信号を入力してその検出信号に基づいて、エアポンプ５を駆動させる駆動信号をエアポンプ５に出力する。この結果、エアポンプ５は、検出器１２０、１２１から制御部１２２に検出信号が出力されている間駆動する。 The control unit 122 is housed in the bottom portion 24 or the storage unit 26. The control unit 122 inputs the detection signals output from the detectors 120 and 121, and outputs a drive signal for driving the air pump 5 to the air pump 5 based on the detection signals. As a result, the air pump 5 is driven while the detection signal is output from the detectors 120 and 121 to the control unit 122.

電源スイッチ１４は、容器部材２の底部２４に設けられている。電源スイッチ１４は、電池１４０に電気的に接続されている。電源スイッチ１４は、オン、オフ操作により、電池１４０から制御部材１２およびエアポンプ５への電力の供給、遮断を行う。電池１４０は、底部２４の下面閉塞部の開口部から底部２４中に収納され、かつ、底部２４に着脱可能に取り付けた底蓋部２５により底部２４中に収納保持される。この結果、底蓋部２５を底部２４から取り外すことにより、電池１４０を底部２４中に収納したり、底部２４中の電池１４０を底部２４中から取り出したりすることができる。 The power switch 14 is provided on the bottom 24 of the container member 2. The power switch 14 is electrically connected to the battery 140. The power switch 14 supplies and shuts off electric power from the battery 140 to the control member 12 and the air pump 5 by turning on and off. The battery 140 is housed in the bottom 24 through the opening of the bottom closing portion of the bottom 24, and is stored and held in the bottom 24 by the bottom lid 25 detachably attached to the bottom 24. As a result, by removing the bottom lid portion 25 from the bottom portion 24, the battery 140 can be stored in the bottom portion 24, and the battery 140 in the bottom portion 24 can be taken out from the bottom portion 24.

（第１空気供給管６、第２空気供給管７の説明）
第１空気供給管６は、図１に示すように、一端６０が噴霧部材３に接続され、他端６１が空気分岐部材８を介してエアポンプ５に接続されている。第１空気供給管６は、エアポンプ５からの空気１０４を噴霧部材３に供給する。第１空気供給管６の一端６０側の部分は、液供給管４の一端４０側の部分と共に、第１管部２７および第２管部２８中に収納されている。 (Explanation of the first air supply pipe 6 and the second air supply pipe 7)
As shown in FIG. 1, one end 60 of the first air supply pipe 6 is connected to the spray member 3, and the other end 61 is connected to the air pump 5 via the air branch member 8. The first air supply pipe 6 supplies the air 104 from the air pump 5 to the spray member 3. The portion 60 side of one end of the first air supply pipe 6 is housed in the first pipe portion 27 and the second pipe portion 28 together with the portion on the one end 40 side of the liquid supply pipe 4.

第２空気供給管７は、図１に示すように、一端７０が液供給管４の他端４１に接続され、他端７１が空気分岐部材８を介してエアポンプ５に接続されている。第２空気供給管７は、エアポンプ５からの空気１０４を液供給管４に供給して、液供給管４の中間部分４２中の液１００を噴霧部材３に供給する。第２空気供給管７の一端７０側の部分（垂直な直線部分）は、そのまま容器部材２の容器部２０中に収納されている。第２空気供給管７の一端７０側の部分と容器部２０の下面閉塞部とは、水密に保たれている。第２空気供給管７の一端７０は、容器部２０中の液面１０２よりも上位に位置する。この結果、液供給管４の他端４１と第２空気供給管７の一端７０との接続部分は、容器部２０中の液面１０２よりも上位に位置する。第２空気供給管７の他端７１側の部分（曲線部分）は、底部２４中に収納されている。 As shown in FIG. 1, one end 70 of the second air supply pipe 7 is connected to the other end 41 of the liquid supply pipe 4, and the other end 71 is connected to the air pump 5 via an air branch member 8. The second air supply pipe 7 supplies the air 104 from the air pump 5 to the liquid supply pipe 4, and supplies the liquid 100 in the intermediate portion 42 of the liquid supply pipe 4 to the spray member 3. The portion 70 side of one end of the second air supply pipe 7 (vertical straight portion) is housed in the container portion 20 of the container member 2 as it is. The portion 70 on one end of the second air supply pipe 7 and the lower surface closed portion of the container portion 20 are kept watertight. One end 70 of the second air supply pipe 7 is located above the liquid level 102 in the container portion 20. As a result, the connecting portion between the other end 41 of the liquid supply pipe 4 and the one end 70 of the second air supply pipe 7 is located above the liquid level 102 in the container portion 20. The portion (curved portion) on the other end 71 side of the second air supply pipe 7 is housed in the bottom portion 24.

第２空気供給管７の断面積Ｓ８は、第１空気供給管６の断面積Ｓ９よりも大きい。この例では、約４：１である。この結果、第２空気供給管７への空気１０４の供給量は、第１空気供給管６への空気１０４の供給量よりも、約４倍多い。なお、第２空気供給管７の断面積Ｓ８と第１空気供給管６の断面積Ｓ９との比は、この例における約４：１以外の比であっても良い。 The cross-sectional area S8 of the second air supply pipe 7 is larger than the cross-sectional area S9 of the first air supply pipe 6. In this example, it is about 4: 1. As a result, the amount of air 104 supplied to the second air supply pipe 7 is about four times larger than the amount of air 104 supplied to the first air supply pipe 6. The ratio of the cross-sectional area S8 of the second air supply pipe 7 to the cross-sectional area S9 of the first air supply pipe 6 may be a ratio other than about 4: 1 in this example.

（空気分岐部材８の説明）

As shown in FIG. 1, the air branch member 8 is provided at a connecting portion between the air pump 5 and the other end 61 of the first air supply pipe 6 and the other end 71 of the second air supply pipe 7. That is, the air branch member 8 is connected to the port for sending out the air 104 of the air pump 5, the other end 61 of the first air supply pipe 6, and the other end 71 of the second air supply pipe 7, respectively. The air branch member 8 branches and supplies the air 104 from the air pump 5 to the first air supply pipe 6 and the second air supply pipe 7 at a ratio of about 1: 4.

The holder portion 90 and the connecting pipe 91 are provided with a liquid passage 93 for supplying the liquid 100 in the container portion 20 of the container member 2 into the liquid supply pipe 4. The holder portion 90 and the connecting pipe 91 are composed of separate parts. The holder portion 90 and the connecting pipe 91 may be composed of one component.

弁体９２は、板形状をなし、ゴム部材などの弾性部材からなる。弁体９２は、円環板形状の固定部９４と、円板形状の可動部９５と、固定部９４と可動部９５を接続する小四角板形状の接続部９６と、から構成されている。固定部９４、可動部９５および接続部９６は、通常、面一の状態にある。固定部９４は、容器部材２の筒部２００の下面とホルダ部９０の上面との間に固定されている。可動部９５は、接続部９６の弾性変形により、固定部９４に対して開閉動して容器部材２の孔２０１を開閉する。すなわち、可動部９５は、エアポンプ５が非駆動時には容器部２０中の液１００の自重で開いて孔２０１を開き、エアポンプ５の駆動時には液通路９３中の液１００もしくは空気１０４の圧力および接続部９６の弾性復帰力で閉じて孔２０１を閉じる。弁体９２は、逆止弁である。 The valve body 92 has a plate shape and is made of an elastic member such as a rubber member. The valve body 92 is composed of a ring plate-shaped fixed portion 94, a disk-shaped movable portion 95, and a small square plate-shaped connecting portion 96 that connects the fixed portion 94 and the movable portion 95. The fixed portion 94, the movable portion 95 and the connecting portion 96 are usually in a flush state. The fixing portion 94 is fixed between the lower surface of the tubular portion 200 of the container member 2 and the upper surface of the holder portion 90. The movable portion 95 opens and closes with respect to the fixed portion 94 due to the elastic deformation of the connecting portion 96 to open and close the hole 201 of the container member 2. That is, when the air pump 5 is not driven, the movable portion 95 is opened by the weight of the liquid 100 in the container portion 20 to open the hole 201, and when the air pump 5 is driven, the pressure and the connection portion of the liquid 100 or the air 104 in the liquid passage 93 are opened. The hole 201 is closed by closing with the elastic return force of 96. The valve body 92 is a check valve.

（実施形態１の作用の説明）
この実施形態１にかかるディスペンサ１は、以上のごとき構成からなり、以下、その作用について説明する。 (Explanation of operation of Embodiment 1)
The dispenser 1 according to the first embodiment has the above configuration, and its operation will be described below.

まず、通常状態、すなわち、エアポンプ５が駆動していない状態の時には、図２に示すように、弁部材９の弁体９２（可動部９５）が容器部材２（容器部２０）中の液１００の自重により開いている。このため、容器部２０中の液１００は、弁部材９の液通路９３を通って液供給管４の中間部分４２に所定量（約２ｍｌ）溜められている。 First, in a normal state, that is, when the air pump 5 is not driven, as shown in FIG. 2, the valve body 92 (movable portion 95) of the valve member 9 is the liquid 100 in the container member 2 (container portion 20). It is open due to its own weight. Therefore, the liquid 100 in the container portion 20 is stored in a predetermined amount (about 2 ml) in the intermediate portion 42 of the liquid supply pipe 4 through the liquid passage 93 of the valve member 9.

つぎに、電源スイッチ１４をオンにする。この状態において、手１３を噴霧部材３に近づける。すると、検出器１２０、１２１が対象物の手１３を検出し、検出器１２０、１２１が検出信号を制御部１２２に出力し、制御部１２２が入力した検出信号に基づいて駆動信号をエアポンプ５の駆動部５０に出力し、駆動部５０が駆動信号により駆動し、エアポンプのポンプ部５１が駆動する。これにより、空気１０４は、エアポンプ５から空気分岐部材８を介して、第１空気供給管６および第２空気供給管７中に、送られる。 Next, the power switch 14 is turned on. In this state, the hand 13 is brought closer to the spray member 3. Then, the detectors 120 and 121 detect the hand 13 of the object, the detectors 120 and 121 output the detection signal to the control unit 122, and the drive signal is sent to the air pump 5 based on the detection signal input by the control unit 122. The output is output to the drive unit 50, the drive unit 50 is driven by the drive signal, and the pump unit 51 of the air pump is driven. As a result, the air 104 is sent from the air pump 5 to the first air supply pipe 6 and the second air supply pipe 7 via the air branch member 8.

第１空気供給管６中に送られた空気１０４は、噴霧部材３まで送られる。一方、第２空気供給管７中に送られた空気１０４は、液供給管４中に送られ、液供給管４の中間部分４２中の液１００を、液供給管４の他端４１側から液供給管４の一端４０側の噴霧部材３まで圧送する。なお、この時には、開いていた弁体９２（可動部９５）が、図３に示すように、閉じる。これにより、空気１０４が弁部材９の液通路９３を通って容器部２０中に入るのを防ぐことができる。 The air 104 sent into the first air supply pipe 6 is sent to the spray member 3. On the other hand, the air 104 sent into the second air supply pipe 7 is sent into the liquid supply pipe 4, and the liquid 100 in the intermediate portion 42 of the liquid supply pipe 4 is sent from the other end 41 side of the liquid supply pipe 4. It is pumped to the spray member 3 on the 40 side at one end of the liquid supply pipe 4. At this time, the valve body 92 (movable portion 95) that was open closes as shown in FIG. As a result, it is possible to prevent the air 104 from entering the container portion 20 through the liquid passage 93 of the valve member 9.

噴霧部材３に送られた液１００は、噴霧部材３において、ノズル形状の液連通路３３の出口３３０から下混合室３２Ｄに流速を上げながら空気１０４よりも先に送られる。この時、液１００の一部は、霧１０３となる。一方、噴霧部材３に送られた空気１０４は、噴霧部材３において、空気連通路３４の出口３４０から上混合室３２Ｕを経て下混合室３２Ｄに送られる。 The liquid 100 sent to the spray member 3 is sent before the air 104 in the spray member 3 while increasing the flow velocity from the outlet 330 of the nozzle-shaped liquid communication passage 33 to the lower mixing chamber 32D. At this time, a part of the liquid 100 becomes mist 103. On the other hand, the air 104 sent to the spray member 3 is sent from the outlet 340 of the air communication passage 34 to the lower mixing chamber 32D via the upper mixing chamber 32U in the spray member 3.

下混合室３２Ｄにそれぞれ送られた液１００と空気１０４とは、ノズル形状の下混合室３２Ｄにおいて、相互に混合されて、液１００は、霧１０３となる。霧１０３は、ノズル形状の下混合室３２Ｄの噴射口３５から外部の手１３に向かって流速を上げながら所定量噴射される（図７参照）。これにより、手１３は、この例の消毒用アルコールの液１００により、消毒される。なお、手１３に当たらなかった霧１０３は、トレー１１の受凹部１１１に受けられる。このため、周囲を霧１０３で汚すことがない。 The liquid 100 and the air 104 sent to the lower mixing chamber 32D are mixed with each other in the nozzle-shaped lower mixing chamber 32D, and the liquid 100 becomes a mist 103. The mist 103 is injected in a predetermined amount from the injection port 35 of the nozzle-shaped lower mixing chamber 32D toward the outer hand 13 while increasing the flow velocity (see FIG. 7). As a result, the hand 13 is disinfected with the rubbing alcohol solution 100 of this example. The fog 103 that did not hit the hand 13 is received by the receiving recess 111 of the tray 11. Therefore, the surrounding area is not polluted with fog 103.

そして、消毒が済んだ時点で、手１３を噴霧部材３から離す。すると、今まで対象物の手１３を検出していた検出器１２０、１２１が対象物の手１３を検出しなくなる。この結果、検出器１２０、１２１から制御部１２２への検出信号の出力が停止し、制御部１２２からエアポンプ５の駆動部５０への駆動信号の出力が停止し、駆動部５０の駆動が停止し、ポンプ部５１の駆動も停止する。これにより、エアポンプ５から空気分岐部材８を介して第１空気供給管６および第２空気供給管７中への空気１０４の供給が停止され、噴霧部材３から手１３に向けての霧１０３の噴射が停止する。 Then, when the disinfection is completed, the hand 13 is separated from the spray member 3. Then, the detectors 120 and 121, which have previously detected the hand 13 of the object, do not detect the hand 13 of the object. As a result, the output of the detection signal from the detectors 120 and 121 to the control unit 122 is stopped, the output of the drive signal from the control unit 122 to the drive unit 50 of the air pump 5 is stopped, and the drive of the drive unit 50 is stopped. , The drive of the pump unit 51 is also stopped. As a result, the supply of air 104 from the air pump 5 to the first air supply pipe 6 and the second air supply pipe 7 via the air branch member 8 is stopped, and the mist 103 from the spray member 3 toward the hand 13 The injection stops.

このように、手１３を噴霧部材３に近づけた時点から手１３を噴霧部材３から離した時点までの時間、検出器１２０、１２１が手１３を検出し、エアポンプ５が駆動し、噴霧部材３から霧１０３が手１３に噴射される。このため、手１３を噴霧部材３に入れ出しする時間を任意に調整することで、手１３に噴射させる霧１０３の量を任意に調整することができる。この結果、検出器１２０、１２１が手１３を検出する時間に基づいて、所定量（約２ｍｌ）以内において任意の量の液１００が霧１０３として噴射される。なお、この例においては、エアポンプ５が約１秒間駆動することにより、約０．５ｍｌの量の液１００が霧１０３として噴射される。この結果、エアポンプ５が約４秒間駆動すると、所定量（約２ｍｌ）の液１００が霧１０３として噴射される。 In this way, the detectors 120 and 121 detect the hand 13 and the air pump 5 drives the spray member 3 during the time from the time when the hand 13 is brought close to the spray member 3 to the time when the hand 13 is separated from the spray member 3. The fog 103 is sprayed onto the hand 13. Therefore, the amount of fog 103 to be sprayed on the hand 13 can be arbitrarily adjusted by arbitrarily adjusting the time for putting the hand 13 in and out of the spray member 3. As a result, an arbitrary amount of the liquid 100 is sprayed as the mist 103 within a predetermined amount (about 2 ml) based on the time when the detectors 120 and 121 detect the hand 13. In this example, the air pump 5 is driven for about 1 second to inject about 0.5 ml of the liquid 100 as the mist 103. As a result, when the air pump 5 is driven for about 4 seconds, a predetermined amount (about 2 ml) of the liquid 100 is injected as the mist 103.

霧１０３の噴射が停止した時、液供給管４の上端部分４Ｕおよび右側部分４Ｒ中に液１００が残っていると、その液１００の自重により、上端部分４Ｕおよび右側部分４Ｒ中の液１００が液供給管４の中間部分４２側に戻る。それに伴って、液１００を圧送していた空気１０４は、第２空気供給管７、空気分岐部材８、第１空気供給管６および噴霧部材３を経て外部に排出される。この結果、噴霧部材３から液１００が垂れるのを防ぐことができる。 When the injection of the mist 103 is stopped, if the liquid 100 remains in the upper end portion 4U and the right side portion 4R of the liquid supply pipe 4, the liquid 100 in the upper end portion 4U and the right side portion 4R is caused by the weight of the liquid 100. Return to the intermediate portion 42 side of the liquid supply pipe 4. Along with this, the air 104 that has pumped the liquid 100 is discharged to the outside through the second air supply pipe 7, the air branch member 8, the first air supply pipe 6, and the spray member 3. As a result, it is possible to prevent the liquid 100 from dripping from the spray member 3.

エアポンプ５の駆動が停止すると、前記の通り、容器部２０中の液１００が弁部材９を介して液供給管４の中間部分４２中に所定量供給される。そして、検出器１２０、１２１が対象物の手１３を再び検出すると、前記の通り、噴霧部材３から霧１０３が手に向かって噴射される。このようにして、容器部２０中の液１００が噴霧部材３から霧１０３として噴射され続けると、容器部２０中の液１００の量が減少する。これにより、容器部２０中の液面１０２が低下するので、液供給管４の中間部分４２中に溜められている液１００の所定量も減少する。この時、容器部材２外の空気（大気）が、容器部２０と密閉蓋部２１との間の隙間、密閉蓋部２１と外蓋部２３との間の隙間および密閉蓋部２１と内蓋部２２との間の隙間を経て、容器部２０中の液面１０２よりも上方の空間中に流入する。このため、容器部２０中は、大気圧と同等もしくはほぼ同等の圧力が維持される。 When the drive of the air pump 5 is stopped, as described above, a predetermined amount of the liquid 100 in the container portion 20 is supplied to the intermediate portion 42 of the liquid supply pipe 4 via the valve member 9. Then, when the detectors 120 and 121 detect the hand 13 of the object again, the mist 103 is ejected from the spray member 3 toward the hand as described above. In this way, when the liquid 100 in the container portion 20 continues to be sprayed as the mist 103 from the spray member 3, the amount of the liquid 100 in the container portion 20 decreases. As a result, the liquid level 102 in the container portion 20 is lowered, so that the predetermined amount of the liquid 100 stored in the intermediate portion 42 of the liquid supply pipe 4 is also reduced. At this time, the air (atmosphere) outside the container member 2 is the gap between the container portion 20 and the sealing lid portion 21, the gap between the sealing lid portion 21 and the outer lid portion 23, and the sealing lid portion 21 and the inner lid. It flows into the space above the liquid level 102 in the container portion 20 through the gap between the portion 22 and the portion 22. Therefore, the pressure in the container portion 20 is maintained at or substantially the same as the atmospheric pressure.

容器部２０中の液１００の量が減少したところで、容器部２０中に液１００を補充する。その場合、まず、容器部２０から外蓋部２３を取り外す（図１０参照）。それから、密閉蓋部２１から内蓋部２２を取り外し、かつ、容器１０１中の液１００を密閉蓋部２１の注入口２１１から容器部２０中に注入する（図１１参照）。それから、容器部２０中の液面１０２が注入口２１１の下側の縁に達すると、容器部２０中が液１００で満杯状態となる。この状態で、密閉蓋部２１の注入口２１１に内蓋部２２を取り付け、かつ、容器部２０に外蓋部２３を取り付ける（図８参照）。これにより、液１００の補充が完了し、噴霧部材３から霧１０３を手に向かって噴射させることができる。 When the amount of the liquid 100 in the container portion 20 has decreased, the liquid 100 is replenished in the container portion 20. In that case, first, the outer lid portion 23 is removed from the container portion 20 (see FIG. 10). Then, the inner lid portion 22 is removed from the sealed lid portion 21, and the liquid 100 in the container 101 is injected into the container portion 20 from the injection port 211 of the sealed lid portion 21 (see FIG. 11). Then, when the liquid level 102 in the container portion 20 reaches the lower edge of the injection port 211, the inside of the container portion 20 is filled with the liquid 100. In this state, the inner lid portion 22 is attached to the injection port 211 of the sealed lid portion 21, and the outer lid portion 23 is attached to the container portion 20 (see FIG. 8). As a result, the replenishment of the liquid 100 is completed, and the mist 103 can be sprayed from the spray member 3 toward the hand.

ここで、図９に示すように、本体１０をトレー１１の嵌合凹部１１０から取り外すことができる。トレー１１から取り外した本体１０を持って噴霧部材３を対象物（手１３以外の対象物）に近づけて、検出器１２０、１２１が対象物を検出すると、噴霧部材３から霧１０３を対象物に噴射させることができる。このように、霧１０３を噴射させたい対象物を手１３以外の対象物に広げることができる。 Here, as shown in FIG. 9, the main body 10 can be removed from the fitting recess 110 of the tray 11. When the spray member 3 is brought close to the object (object other than the hand 13) by holding the main body 10 removed from the tray 11 and the detectors 120 and 121 detect the object, the mist 103 is set as the object from the spray member 3. It can be sprayed. In this way, the object to be sprayed with the mist 103 can be spread to objects other than the hand 13.

（実施形態１の効果の説明）
この実施形態１にかかるディスペンサ１は、以上のごとき構成および作用からなり、以下、その効果について説明する。 (Explanation of Effect of Embodiment 1)
The dispenser 1 according to the first embodiment has the above-mentioned configuration and operation, and its effects will be described below.

この実施形態１にかかるディスペンサ１は、制御部材１２の制御によりエアポンプ５を駆動させて、液供給管４の中間部分４２中に所定量（約２ｍｌ）溜められている液１００を、霧１０３として噴射させるものである。このため、この実施形態１にかかるディスペンサ１は、制御部材１２の制御によるエアポンプ５の駆動時間に基づいて、液供給管４の中間部分４２中に溜められている所定量（約２ｍｌ）以内において任意の量の液１００を霧１０３として噴射させることができる。すなわち、この実施形態１にかかるディスペンサ１は、所定量以内において任意の量の液１００を噴射させることができる。 In the dispenser 1 according to the first embodiment, the air pump 5 is driven by the control of the control member 12, and the liquid 100 stored in the intermediate portion 42 of the liquid supply pipe 4 in a predetermined amount (about 2 ml) is used as the mist 103. It is to be sprayed. Therefore, the dispenser 1 according to the first embodiment is within a predetermined amount (about 2 ml) stored in the intermediate portion 42 of the liquid supply pipe 4 based on the driving time of the air pump 5 controlled by the control member 12. An arbitrary amount of the liquid 100 can be sprayed as the mist 103. That is, the dispenser 1 according to the first embodiment can inject an arbitrary amount of the liquid 100 within a predetermined amount.

この実施形態１にかかるディスペンサ１は、エアポンプ５からの空気１０４を、空気分岐部材８を介して、２系統の第１空気供給管６と第２空気供給管７とに、それぞれ分岐させ、一方の系統の第２空気供給管７の空気１０４で、液供給管４の中間部分４２中に溜められている液１００を噴霧部材３に供給し、かつ、他方の系統の第１空気供給管６の空気１０４で、液１００を噴霧部材３から霧１０３として噴射させるものである。このため、この実施形態１にかかるディスペンサ１は、所定量以内において任意の量の液１００を、確実に霧１０３として噴射させることができる。しかも、この実施形態１にかかるディスペンサ１は、噴霧部材３に液１００と空気１０４とを供給して、噴霧部材３から霧１０３を噴射させるものであるから、使用する液１００がこの例の揮発性を有する消毒用アルコールの場合、液１００を霧１０３とするのに最適である。 In the dispenser 1 according to the first embodiment, the air 104 from the air pump 5 is branched into two systems of the first air supply pipe 6 and the second air supply pipe 7 via the air branch member 8, respectively. The air 104 of the second air supply pipe 7 of the system supplies the liquid 100 stored in the intermediate portion 42 of the liquid supply pipe 4 to the spray member 3, and the first air supply pipe 6 of the other system. In the air 104 of the above, the liquid 100 is sprayed from the spray member 3 as a mist 103. Therefore, the dispenser 1 according to the first embodiment can reliably inject an arbitrary amount of the liquid 100 as a mist 103 within a predetermined amount. Moreover, since the dispenser 1 according to the first embodiment supplies the liquid 100 and the air 104 to the spray member 3 and injects the mist 103 from the spray member 3, the liquid 100 used is volatile in this example. In the case of rubbing alcohol having properties, the liquid 100 is most suitable for forming the mist 103.

この実施形態１にかかるディスペンサ１は、図１に示すように、第２空気供給管７の断面積Ｓ８が第１空気供給管６の断面積Ｓ９よりも大きい。この例では、第２空気供給管７の断面積Ｓ８と第１空気供給管６の断面積Ｓ９との比が約４：１であり、第２空気供給管７への空気１０４の供給量は、第１空気供給管６への空気１０４の供給量よりも、約４倍多い。このため、この実施形態１にかかるディスペンサ１は、第２空気供給管７中の空気１０４により、液供給管４の中間部分４２中に一時溜められている液１００を噴霧部材３に効率良く送ることができる。一方、第１空気供給管６中の空気１０４により、液１００を噴霧部材３から霧１０３として効率良く噴射させることができる。なお、第２空気供給管７の断面積Ｓ８と第１空気供給管６の断面積Ｓ９の比の相対関係は、いろいろな比を試した結果、約４：１が最も効率が良く液１００を噴霧部材３に送ることができる。無論、第２空気供給管７の断面積Ｓ８と第１空気供給管６の断面積Ｓ９との比は、この例における約４：１以外の比であっても良い。 As shown in FIG. 1, in the dispenser 1 according to the first embodiment, the cross-sectional area S8 of the second air supply pipe 7 is larger than the cross-sectional area S9 of the first air supply pipe 6. In this example, the ratio of the cross-sectional area S8 of the second air supply pipe 7 to the cross-sectional area S9 of the first air supply pipe 6 is about 4: 1, and the amount of air 104 supplied to the second air supply pipe 7 is , About 4 times more than the amount of air 104 supplied to the first air supply pipe 6. Therefore, the dispenser 1 according to the first embodiment efficiently sends the liquid 100 temporarily stored in the intermediate portion 42 of the liquid supply pipe 4 to the spray member 3 by the air 104 in the second air supply pipe 7. be able to. On the other hand, the air 104 in the first air supply pipe 6 can efficiently inject the liquid 100 from the spray member 3 as mist 103. As for the relative relationship between the cross-sectional area S8 of the second air supply pipe 7 and the cross-sectional area S9 of the first air supply pipe 6, as a result of trying various ratios, about 4: 1 is the most efficient liquid 100. It can be sent to the spray member 3. Of course, the ratio of the cross-sectional area S8 of the second air supply pipe 7 to the cross-sectional area S9 of the first air supply pipe 6 may be a ratio other than about 4: 1 in this example.

この実施形態１にかかるディスペンサ１は、図１に示すように、液供給管４の一端４０側の少なくとも一部分（この例では、一端４０から上端部分４Ｕを経て右側部分４Ｒのうち液面１０２に対応する箇所までの部分）が、容器部材２の容器部２０中の液面１０２よりも上位に位置する。このため、この実施形態１にかかるディスペンサ１は、容器部２０中から弁部材９を介して液供給管４の中間部分４２中に供給された液体１００が、その中間部分４２中から右側部分４Ｒ中のうち液面１０２に対応する箇所よりも上位に位置することがない。この結果、この実施形態１にかかるディスペンサ１は、中間部分４２中の液体１００が、液供給管４の液面１０２よりも上位に位置する部分を通って噴霧部材３から漏れるのを防ぐことができる。 As shown in FIG. 1, the dispenser 1 according to the first embodiment reaches at least a part of the liquid supply pipe 4 on the one end 40 side (in this example, from one end 40 through the upper end portion 4U to the liquid level 102 of the right side portion 4R. The portion up to the corresponding portion) is located above the liquid level 102 in the container portion 20 of the container member 2. Therefore, in the dispenser 1 according to the first embodiment, the liquid 100 supplied from the container portion 20 to the intermediate portion 42 of the liquid supply pipe 4 via the valve member 9 is supplied from the intermediate portion 42 to the right side portion 4R. It is not located higher than the portion corresponding to the liquid level 102 in the inside. As a result, the dispenser 1 according to the first embodiment can prevent the liquid 100 in the intermediate portion 42 from leaking from the spray member 3 through the portion located above the liquid level 102 of the liquid supply pipe 4. it can.

この実施形態１にかかるディスペンサ１は、図１に示すように、液供給管４の他端４１と第２空気供給管７の一端７０との接続部分が、容器部材２の容器部２０中の液面１０２よりも上位に位置する。このため、この実施形態１にかかるディスペンサ１は、容器部２０中から弁部材９を介して液供給管４の中間部分４２中に供給された液体１００が、その中間部分４２中から左側部分４Ｌ中のうち液面１０２に対応する箇所よりも上位に位置することがない。この結果、この実施形態１にかかるディスペンサ１は、中間部分４２中の液体１００が、液供給管４の液面１０２よりも上位に位置する部分を通って第２空気供給管７中に流入するのを防ぐことができる。しかも、この実施形態１にかかるディスペンサ１は、容器部２０中の液１００が液供給管４の他端４１と第２空気供給管７の一端７０との接続部分から液供給管４中や第２空気供給管７中に浸入したりするのを防ぐことができる。 In the dispenser 1 according to the first embodiment, as shown in FIG. 1, the connecting portion between the other end 41 of the liquid supply pipe 4 and one end 70 of the second air supply pipe 7 is in the container portion 20 of the container member 2. It is located above the liquid level 102. Therefore, in the dispenser 1 according to the first embodiment, the liquid 100 supplied from the container portion 20 to the intermediate portion 42 of the liquid supply pipe 4 via the valve member 9 is placed in the middle portion 42 to the left side portion 4L. It is not located higher than the portion corresponding to the liquid level 102 in the inside. As a result, in the dispenser 1 according to the first embodiment, the liquid 100 in the intermediate portion 42 flows into the second air supply pipe 7 through the portion located above the liquid level 102 of the liquid supply pipe 4. Can be prevented. Moreover, in the dispenser 1 according to the first embodiment, the liquid 100 in the container portion 20 is connected to the other end 41 of the liquid supply pipe 4 and one end 70 of the second air supply pipe 7 into the liquid supply pipe 4 or the first. 2 It is possible to prevent the air from entering the air supply pipe 7.

この実施形態１にかかるディスペンサ１は、図１に示すように、液供給管４の一端４０側部分の断面積Ｓ６が液供給管４の中間部分４２の断面積Ｓ７よりも小さい。このため、この実施形態１にかかるディスペンサ１は、液供給管４の一端４０側部分中を圧送される液１００の流速が液供給管４の中間部分４２中を圧送される液１００の流速よりも速い。この結果、この実施形態１にかかるディスペンサ１は、噴霧部材３に圧送される液１００の流速が第１空気供給管６を経て噴霧部材３に送られる空気１０４の流速よりも速い。これにより、この実施形態１にかかるディスペンサ１は、空気１０４と、流速が空気１０４の流速よりも速い液１００とにより、噴霧部材３から良好な霧１０３（細かい霧１０３）を噴射させることができる。なお、液供給管４の一端４０側部分の断面積Ｓ６と中間部分４２の断面積Ｓ７の大小の相対関係は、いろいろ試した結果、一端４０側部分の断面積Ｓ６が中間部分４２の断面積Ｓ７より小さい相対関係のものが良好な霧１０３（細かい霧１０３）を噴射させるのに適している。 In the dispenser 1 according to the first embodiment, as shown in FIG. 1, the cross-sectional area S6 of the one end 40 side portion of the liquid supply pipe 4 is smaller than the cross-sectional area S7 of the intermediate portion 42 of the liquid supply pipe 4. Therefore, in the dispenser 1 according to the first embodiment, the flow velocity of the liquid 100 pumped through the one end 40 side portion of the liquid supply pipe 4 is higher than the flow velocity of the liquid 100 pumped through the intermediate portion 42 of the liquid supply pipe 4. Is also fast. As a result, in the dispenser 1 according to the first embodiment, the flow velocity of the liquid 100 pressure-fed to the spray member 3 is faster than the flow velocity of the air 104 sent to the spray member 3 via the first air supply pipe 6. As a result, the dispenser 1 according to the first embodiment can inject a good mist 103 (fine mist 103) from the spray member 3 by the air 104 and the liquid 100 whose flow velocity is faster than the flow velocity of the air 104. .. As a result of various trials regarding the relative relationship between the cross-sectional area S6 of the one end 40 side portion of the liquid supply pipe 4 and the cross-sectional area S7 of the intermediate portion 42, the cross-sectional area S6 of the one end 40 side portion is the cross-sectional area of the intermediate portion 42. Those having a relative relationship smaller than S7 are suitable for injecting a good mist 103 (fine mist 103).

この実施形態１にかかるディスペンサ１は、図４に示すように、噴霧部材３の混合室３２であって下混合室３２Ｄ（以下、単に「混合室３２」と称する）の噴射口３５側の断面積Ｓ１が混合室３２の液連通路３３および空気連通路３４側の断面積Ｓ２よりも小さい。すなわち、混合室３２がノズル形状をなしている。このため、この実施形態１にかかるディスペンサ１は、混合室３２において混合された液１００と空気１０４とを、噴霧部材３の噴射口３５から良好な霧１０３（細かい霧１０３）として噴射させることができる。 As shown in FIG. 4, the dispenser 1 according to the first embodiment is a mixing chamber 32 of the spray member 3, and is a disconnection on the injection port 35 side of the lower mixing chamber 32D (hereinafter, simply referred to as “mixing chamber 32”). The area S1 is smaller than the cross-sectional area S2 on the liquid communication passage 33 and the air communication passage 34 side of the mixing chamber 32. That is, the mixing chamber 32 has a nozzle shape. Therefore, the dispenser 1 according to the first embodiment can inject the liquid 100 and the air 104 mixed in the mixing chamber 32 from the injection port 35 of the spray member 3 as a good mist 103 (fine mist 103). it can.

実施形態１にかかるディスペンサ１は、図４に示すように、液連通路３３の混合室３２側の出口３３０の断面積Ｓ３が、液連通路３３の液供給管４側の入口３３１の断面積Ｓ４よりも小さい。すなわち、液連通路３３が混合室３２と同様にノズル形状をなしている。このため、この実施形態１にかかるディスペンサ１は、液連通路３３の出口３３０から下混合室３２Ｄに送られる液１００の流速が、空気連通路３４の出口３４０から上混合室３２Ｕを経て下混合室３２Ｄに送られる空気１０４の流速よりも速い。この結果、この実施形態１にかかるディスペンサ１は、下混合室３２Ｄに流速を上げながら空気１０４よりも先に送られた液１００が良好な霧１０３（細かい霧１０３）となる。しかも、この実施形態１にかかるディスペンサ１は、ノズル形状の液連通路３３とノズル形状の下混合室３２Ｄとの２重のノズル構造により、液１００と空気１０４とを、液連通路３３と下混合室３２Ｄとを経て、噴霧部材３の噴射口３５から良好な霧１０３（細かい霧１０３）として噴射させることができる。 In the dispenser 1 according to the first embodiment, as shown in FIG. 4, the cross-sectional area S3 of the outlet 330 on the mixing chamber 32 side of the liquid-series passage 33 is the cross-sectional area of the inlet 331 on the liquid supply pipe 4 side of the liquid-series passage 33. Smaller than S4. That is, the liquid passage 33 has a nozzle shape similar to the mixing chamber 32. Therefore, in the dispenser 1 according to the first embodiment, the flow velocity of the liquid 100 sent from the outlet 330 of the liquid communication passage 33 to the lower mixing chamber 32D is lower mixed from the outlet 340 of the air communication passage 34 through the upper mixing chamber 32U. It is faster than the flow velocity of the air 104 sent to the chamber 32D. As a result, in the dispenser 1 according to the first embodiment, the liquid 100 sent before the air 104 while increasing the flow velocity to the lower mixing chamber 32D becomes a good mist 103 (fine mist 103). Moreover, the dispenser 1 according to the first embodiment has a double nozzle structure of a nozzle-shaped liquid passage 33 and a nozzle-shaped lower mixing chamber 32D, so that the liquid 100 and the air 104 are connected to the liquid passage 33 and the bottom. It can be injected as a good mist 103 (fine mist 103) from the injection port 35 of the spray member 3 through the mixing chamber 32D.

実施形態１にかかるディスペンサ１は、図４に示すように、液連通路３３の混合室３２側の出口３３０の断面積Ｓ３が、空気連通路３４の混合室３２（上混合室３２Ｕ）側の出口３４０の断面積Ｓ５よりも小さい。この例では、約１：２である。このため、この実施形態１にかかるディスペンサ１は、液連通路３３の出口３３０から下混合室３２Ｄ中に送られる液１００の量が、空気連通路３４の出口３４０から上混合室３２Ｕを経て下混合室３２Ｄ中に送られる空気１０４の量よりも少ない。この結果、この実施形態１にかかるディスペンサ１は、液１００と空気１０４とを、下混合室３２Ｄにおいて、最適な量の混合比で混合させて、噴霧部材３の噴射口３５から良好な霧１０３（細かい霧１０３）として噴射させることができる。なお、液連通路３３の出口３３０の断面積Ｓ３と空気連通路３４の出口３４０の断面積Ｓ５の大小の相対関係は、いろいろ試した結果、液連通路３３の出口３３０の断面積Ｓ３が空気連通路３４の出口３４０の断面積Ｓ５より小さい相対関係のものが良好な霧１０３（細かい霧１０３）を噴射させるのに適している。 In the dispenser 1 according to the first embodiment, as shown in FIG. 4, the cross-sectional area S3 of the outlet 330 on the mixing chamber 32 side of the liquid passage 33 is on the mixing chamber 32 (upper mixing chamber 32U) side of the air passage 34. It is smaller than the cross-sectional area S5 of the outlet 340. In this example, it is about 1: 2. Therefore, in the dispenser 1 according to the first embodiment, the amount of the liquid 100 sent from the outlet 330 of the liquid communication passage 33 into the lower mixing chamber 32D is lowered from the outlet 340 of the air communication passage 34 through the upper mixing chamber 32U. Less than the amount of air 104 sent into the mixing chamber 32D. As a result, in the dispenser 1 according to the first embodiment, the liquid 100 and the air 104 are mixed in the lower mixing chamber 32D at an optimum amount of mixing ratio, and a good mist 103 is mixed from the injection port 35 of the spray member 3. It can be sprayed as (fine mist 103). As a result of various trials, the relative relationship between the cross-sectional area S3 of the outlet 330 of the liquid passage 33 and the cross-sectional area S5 of the outlet 340 of the air passage 34 is that the cross-sectional area S3 of the outlet 330 of the liquid passage 33 is air. Those having a relative relationship smaller than the cross-sectional area S5 of the outlet 340 of the communication passage 34 are suitable for injecting a good fog 103 (fine fog 103).

実施形態１にかかるディスペンサ１は、図４に示すように、液連通路３３の混合室３２側の出口３３０から噴射口３５までの距離Ｈ１が、空気連通路３４の混合室３２側の出口３４０から噴射口３５までの距離Ｈ２よりも小さい。このため、この実施形態１にかかるディスペンサ１は、液連通路３３の出口３３０から送られた液１００が空気連通路３４の出口３４０から送られた液１０４よりも速く噴射口３５に達する。この結果、この実施形態１にかかるディスペンサ１は、空気１０４よりも先に噴射口３５に達した液１００が噴射口３５から良好な霧１０３（細かい霧１０３）として噴射される。しかも、この実施形態１にかかるディスペンサ１は、液連通路３３の出口３３０から下混合室３２Ｄ中に送られる液１００の量が、空気連通路３４の出口３４０から上混合室３２Ｕを経て下混合室３２Ｄ中に送られる空気１０４の量よりも少ないこととの相乗効果により、噴霧部材３の噴射口３５から良好な霧１０３（細かい霧１０３）を噴射させることができる。なお、液連通路３３の出口３３０から噴射口３５までの距離Ｈ１と空気連通路３４の出口３４０から噴射口３５までの距離Ｈ２の大小の相対関係は、いろいろ試した結果、液連通路３３の出口３３０から噴射口３５までの距離Ｈ１が空気連通路３４の出口３４０から噴射口３５までの距離Ｈ２より小さい相対関係のものが良好な霧１０３（細かい霧１０３）を噴射させるのに適している。 In the dispenser 1 according to the first embodiment, as shown in FIG. 4, the distance H1 from the outlet 330 on the mixing chamber 32 side of the liquid passage 33 to the injection port 35 is the outlet 340 on the mixing chamber 32 side of the air passage 34. It is smaller than the distance H2 from the injection port 35 to the injection port 35. Therefore, in the dispenser 1 according to the first embodiment, the liquid 100 sent from the outlet 330 of the liquid passage 33 reaches the injection port 35 faster than the liquid 104 sent from the outlet 340 of the air passage 34. As a result, in the dispenser 1 according to the first embodiment, the liquid 100 that reaches the injection port 35 before the air 104 is injected from the injection port 35 as a good mist 103 (fine mist 103). Moreover, in the dispenser 1 according to the first embodiment, the amount of the liquid 100 sent from the outlet 330 of the liquid communication passage 33 into the lower mixing chamber 32D is mixed from the outlet 340 of the air communication passage 34 through the upper mixing chamber 32U. Due to the synergistic effect of being less than the amount of air 104 sent into the chamber 32D, a good mist 103 (fine mist 103) can be injected from the injection port 35 of the spray member 3. As a result of various trials, the relative relationship between the distance H1 from the outlet 330 of the liquid passage 33 to the injection port 35 and the distance H2 from the outlet 340 of the air passage 34 to the injection port 35 was found in the liquid passage 33. A relative relationship in which the distance H1 from the outlet 330 to the injection port 35 is smaller than the distance H2 from the outlet 340 to the injection port 35 of the air passage 34 is suitable for injecting a good mist 103 (fine mist 103). ..

実施形態１にかかるディスペンサ１は、噴霧部材３に近づいた対象物としての手１３を検出して検出信号を出力する検出器１２０、１２１と、検出器１２０、１２１から出力された検出信号を入力して検出信号に基づいて、エアポンプ５を駆動させる駆動信号をエアポンプ５に出力する制御部１２２と、を備える。このため、この実施形態１にかかるディスペンサ１は、検出器１２０、１２１が対象物としての手１３を検出すると、噴霧部材３から霧１０３が手１３に噴射されるので、ディスペンサ１に非接触状態で使用することができる。しかも、この実施形態１にかかるディスペンサ１は、検出器１２０、１２１が対象物としての手１３を検出している間、エアポンプ５が制御部材１２の制御により駆動するので、検出器１２０、１２１が手１３を検出している時間、すなわち、手１３を噴霧部材３に入れ出しする時間を任意に調整することで、手１３に噴射させる霧１０３の量を任意に調整することができる。これにより、実施形態１にかかるディスペンサ１は、所定量（約２ｍｌ）以内において任意の量の液１００を、正確にかつ確実に、霧１０３として噴霧部材３から手１３に向かって噴射させることができる。 The dispenser 1 according to the first embodiment inputs the detectors 120 and 121 that detect the hand 13 as an object approaching the spray member 3 and output a detection signal, and the detection signals output from the detectors 120 and 121. A control unit 122 that outputs a drive signal for driving the air pump 5 to the air pump 5 based on the detection signal is provided. Therefore, in the dispenser 1 according to the first embodiment, when the detectors 120 and 121 detect the hand 13 as an object, the mist 103 is ejected from the spray member 3 to the hand 13, so that the dispenser 1 is in a non-contact state. Can be used in. Moreover, in the dispenser 1 according to the first embodiment, the air pump 5 is driven by the control of the control member 12 while the detectors 120 and 121 detect the hand 13 as an object, so that the detectors 120 and 121 By arbitrarily adjusting the time during which the hand 13 is detected, that is, the time during which the hand 13 is taken in and out of the spray member 3, the amount of fog 103 sprayed on the hand 13 can be arbitrarily adjusted. As a result, the dispenser 1 according to the first embodiment can accurately and surely inject an arbitrary amount of the liquid 100 within a predetermined amount (about 2 ml) from the spray member 3 toward the hand 13 as a mist 103. it can.

An agent, a foam hand soap for children's play (for 3D art), or a diluting liquid (the dilution ratio is, for example, 3 to 5 times, but is not particularly limited).

この実施形態２にかかるディスペンサ１Ａは、前記の実施形態１にかかるディスペンサ１において、第１空気開閉弁１５Ａと、第２空気開閉弁１６Ａと、泡供給管１７Ａと、液切換弁１８Ａと、泡吐出部材１９Ａと、を備える。 The dispenser 1A according to the second embodiment is the first air on-off valve 15A, the second air on-off valve 16A, the foam supply pipe 17A, the liquid switching valve 18A, and the foam in the dispenser 1 according to the first embodiment. A discharge member 19A is provided.

第１空気開閉弁１５Ａは、空気分岐部材８のうちエアポンプ５に対して反対側、この例では、空気分岐部材８と第１空気供給管６の他端６１との間、に設けられている。第１空気開閉弁１５Ａは、開状態の時には、エアポンプ５からの空気１０４を空気分岐部材８を介して第１空気供給管６と第２空気供給管７とに分岐させる。また、第１空気開閉弁１５Ａは、閉状態の時には、エアポンプ５からの空気１０４を第１空気供給管６に送らずに第２空気供給管７のみに送る。 The first air on-off valve 15A is provided on the opposite side of the air branch member 8 with respect to the air pump 5, in this example, between the air branch member 8 and the other end 61 of the first air supply pipe 6. .. When the first air on-off valve 15A is in the open state, the air 104 from the air pump 5 is branched into the first air supply pipe 6 and the second air supply pipe 7 via the air branch member 8. Further, when the first air on-off valve 15A is in the closed state, the air 104 from the air pump 5 is not sent to the first air supply pipe 6, but is sent only to the second air supply pipe 7.

第２空気開閉弁１６Ａは、容器部材２の容器部２０中の液面１０２よりも上位に位置する液供給管４の他端４１と第２空気供給管７の一端７０との接続部分、この例では、液供給管４の他端４１側、に設けられている。第２空気開閉弁１６Ａは、閉状態の時には、容器部２０中と液供給管４中および第２空気供給管７中とが非連通状態である。第２空気開閉弁１６Ａは、開状態の時には、容器部２０中と液供給管４中および第２空気供給管７中とが連通状態である。第２空気開閉弁１６Ａは、開状態の時において、容器部２０中、液供給管４中および第２空気供給管７中の圧力を調整する。すなわち、エアポンプ５の駆動時には、エアポンプ５からの空気１０４の大部分が液供給管４中に供給されて液供給管４の中間部分４２中の液１００Ａと混同して泡１０５となり、その泡１０５が泡吐出部材１９Ａに送られる。また、エアポンプ５の非駆動時には、主に液供給管４中の空気１０４が容器部２０中に抜けて、泡吐出部材１９Ａ中の泡１０５が液供給管４中に戻されて泡吐出部材１９Ａから外部に垂れ落ちる（漏れる）のを防ぐことができる。なお、第２空気開閉弁１６Ａは、第２空気供給管７の一端７０側に設けても良い。 The second air on-off valve 16A is a connecting portion between the other end 41 of the liquid supply pipe 4 located above the liquid level 102 in the container portion 20 of the container member 2 and one end 70 of the second air supply pipe 7. In the example, it is provided on the other end 41 side of the liquid supply pipe 4. When the second air on-off valve 16A is in the closed state, the container portion 20 and the liquid supply pipe 4 and the second air supply pipe 7 are in a non-communication state. When the second air on-off valve 16A is in the open state, the container portion 20 and the liquid supply pipe 4 and the second air supply pipe 7 are in a communicating state. The second air on-off valve 16A adjusts the pressure in the container portion 20, the liquid supply pipe 4, and the second air supply pipe 7 when the second air on-off valve 16A is in the open state. That is, when the air pump 5 is driven, most of the air 104 from the air pump 5 is supplied into the liquid supply pipe 4 and confused with the liquid 100A in the intermediate portion 42 of the liquid supply pipe 4 to form bubbles 105. Is sent to the foam discharge member 19A. Further, when the air pump 5 is not driven, the air 104 in the liquid supply pipe 4 mainly escapes into the container portion 20, and the foam 105 in the foam discharge member 19A is returned to the liquid supply pipe 4 to return the foam discharge member 19A. It is possible to prevent it from dripping (leaking) from the outside. The second air on-off valve 16A may be provided on one end 70 side of the second air supply pipe 7.

泡供給管１７Ａは、一端が、液供給管４の中間部分４２から一端４０までの部分であって容器部２０中の液面１０２よりも上位に位置する箇所に、接続されている。この箇所は、この例では、液供給管４の右側部分４Ｒのうち上端部分４Ｕに近接する箇所である。 One end of the foam supply pipe 17A is connected to a portion from the intermediate portion 42 to one end 40 of the liquid supply pipe 4 and located above the liquid level 102 in the container portion 20. In this example, this portion is a portion of the right side portion 4R of the liquid supply pipe 4 that is close to the upper end portion 4U.

液切換弁１８Ａは、液供給管４と泡供給管１７Ａとの接続部分に設けられている。液切換弁１８Ａは、第１位置に切り換えられた時には、液供給管４の中間部分４２中の液１００を液供給管４の上端部分４Ｕ中に供給する。液切換弁１８Ａは、第２位置に切り換えられた時には、液供給管４の中間部分４２中において液１００Ａと空気１０４との混合により発泡した泡１０５を泡供給管１７Ａ中に供給する。 The liquid switching valve 18A is provided at a connecting portion between the liquid supply pipe 4 and the foam supply pipe 17A. When the liquid switching valve 18A is switched to the first position, the liquid 100 in the intermediate portion 42 of the liquid supply pipe 4 is supplied into the upper end portion 4U of the liquid supply pipe 4. When the liquid switching valve 18A is switched to the second position, the foam 105 foamed by mixing the liquid 100A and the air 104 in the intermediate portion 42 of the liquid supply pipe 4 is supplied into the foam supply pipe 17A.

泡吐出部材１９Ａは、泡供給管１７Ａの他端に設けられている。泡吐出部材１９Ａは、泡供給管１７Ａからの泡１０５を外部に吐出させる。泡吐出部材１９Ａは、１個もしくは複数個のメッシュフィルタなどの発泡部材（図示せず）を有する。発泡部材は、泡１０５の径を調整して、細やかな泡１０５を得ることができる。 The foam discharge member 19A is provided at the other end of the foam supply pipe 17A.

The foam ejection member 19A has one or a plurality of foam members (not shown) such as a mesh filter. The foam member can adjust the diameter of the foam 105 to obtain a fine foam 105.

（実施形態２の作用の説明）
この実施形態２にかかるディスペンサ１Ａは、以上のごとき構成からなり、以下、その作用について説明する。 (Explanation of operation of Embodiment 2)
The dispenser 1A according to the second embodiment has the above configuration, and its operation will be described below.

まず、第１空気開閉弁１５Ａを開状態とし、第２空気開閉弁１６Ａを閉状態とし、液切換弁１８Ａを第１位置に切り換えた状態とする。すると、前記の実施形態１にかかるディスペンサ１の作用に示すように、噴霧部材３から霧１０３が噴射される。 First, the first air on-off valve 15A is opened, the second air on-off valve 16A is closed, and the liquid switching valve 18A is switched to the first position. Then, as shown in the operation of the dispenser 1 according to the first embodiment, the mist 103 is ejected from the spray member 3.

つぎに、第１空気開閉弁１５Ａを閉状態とし、第２空気開閉弁１６Ａを開状態とし、液切換弁１８Ａを第２位置に切り換えた状態とする。ここで、検出器１２０、１２１が手１３を検出すると、制御部１２２の制御により、エアポンプ５が駆動して、空気１０４が空気分岐部材８を経て第２空気供給管７のみに送られる。第２空気供給管７のみに送られた空気１０４は、液供給管４中に供給され、液供給管４の中間部分４２中に所定量一時溜められている液１００Ａと混合する。混合した空気１０４と液１００Ａとは、液供給管４の中間部分４２中において発泡して泡１０５となる。 Next, the first air on-off valve 15A is closed, the second air on-off valve 16A is opened, and the liquid switching valve 18A is switched to the second position. Here, when the detectors 120 and 121 detect the hand 13, the air pump 5 is driven by the control of the control unit 122, and the air 104 is sent only to the second air supply pipe 7 via the air branch member 8. The air 104 sent only to the second air supply pipe 7 is supplied into the liquid supply pipe 4 and mixed with the liquid 100A temporarily stored in a predetermined amount in the intermediate portion 42 of the liquid supply pipe 4. The mixed air 104 and the liquid 100A foam in the intermediate portion 42 of the liquid supply pipe 4 to form bubbles 105.

液供給管４の中間部分４２中の泡１０５は、液切換弁１８Ａを経て泡供給管１７Ａ中に供給され、かつ、泡供給管１７Ａを経て泡吐出部材１９Ａに供給される。泡吐出部材１９Ａに供給された泡１０５は、泡吐出部材１９Ａにおいて発泡部材により細やかな泡１０５となり、泡吐出部材１９Ａから外部に吐出される。この泡１０５の泡吐出部材１９Ａからの吐出量は、前記の実施形態１にかかるディスペンサ１と同様に、液供給管４の中間部分４２中に溜められている液１００Ａの所定量（約２ｍｌ）以内における任意の量である。 The foam 105 in the intermediate portion 42 of the liquid supply pipe 4 is supplied into the foam supply pipe 17A via the liquid switching valve 18A, and is supplied to the foam discharge member 19A via the foam supply pipe 17A. The foam 105 supplied to the foam discharge member 19A becomes fine bubbles 105 by the foam member in the foam discharge member 19A, and is discharged from the foam discharge member 19A to the outside. The discharge amount of the foam 105 from the foam discharge member 19A is a predetermined amount (about 2 ml) of the liquid 100A stored in the intermediate portion 42 of the liquid supply pipe 4, similarly to the dispenser 1 according to the first embodiment. Any amount within.

エアポンプ５の駆動が停止すると、液供給管４の右側部分４Ｒ中および泡供給管１７Ａ中に泡１０５が残っていると、その泡１０５の自重により、液供給管４の右側部分４Ｒ中および泡供給管１７Ａ中に泡１０５が液供給管４の中間部分４２側に戻る。それに伴って、液１００Ａを圧送していた空気１０４は、第２空気開閉弁１６Ａを経て容器部材２の容器部２０中に排出される。なお、このとき、若干の泡１０５が、空気１０４と共に、第２空気開閉弁１６Ａを経て容器部２０中に排出される。この結果、泡吐出部材１９Ａから泡１０５が垂れるのを防ぐことができる。 When the drive of the air pump 5 is stopped, if bubbles 105 remain in the right side portion 4R of the liquid supply pipe 4 and in the foam supply pipe 17A, the weight of the bubbles 105 causes the bubbles in the right side portion 4R of the liquid supply pipe 4 and the bubbles. The foam 105 returns to the intermediate portion 42 side of the liquid supply pipe 4 in the supply pipe 17A.
