本考案は手指消毒装置等に用いられる超音波式霧化装置の改良に関するもので ある。 The present invention relates to an improvement of an ultrasonic atomizer used in a hand disinfection device and the like.

未だ公知公用ではないが、この種の超音波式霧化装置に関する考案が出願人か ら提案されている（実願平２−１１７９９０号）。 Although not yet publicly known, the applicant has proposed a device relating to this type of ultrasonic atomization device (Japanese Patent Application No. 2-117990).
【０００３】 この超音波式霧化装置は、高周波信号を印加することによって振動を発生する 振動子と、振動子で発生した振動を振幅を拡大して出力するホ−ンと、霧化され る液体を貯蔵するタンクと、タンク内の液体をホ−ンに給送するポンプとを備え 、ホ−ンに供給された液体をホ−ンの出力振動で霧化するようになっている。ま た、振動子で発生する振動の振幅は温度によって変化するため、振動子の周辺温 度を検出する温度センサを設け、その検出温度に基づいて振動子の振幅やポンプ の流量を変えて常に安定した散布形態が形成されるようにしている。This ultrasonic atomization device is atomized with a vibrator that generates vibration by applying a high-frequency signal, and a horn that expands the vibration generated by the vibrator and outputs the expanded vibration. A tank for storing the liquid and a pump for feeding the liquid in the tank to the horn are provided, and the liquid supplied to the horn is atomized by the output vibration of the horn. In addition, since the amplitude of the vibration generated by the vibrator changes depending on the temperature, a temperature sensor that detects the ambient temperature of the vibrator is installed, and the amplitude of the vibrator and the flow rate of the pump are changed based on the detected temperature. A stable spray form is formed.

しかしながら、前記振幅の温度変化は振動子の周辺温度よりもホ−ンに供給さ れる液体の温度の方が依存性が高いということが出願人の事後研究によって判明 した。つまり、タンク内に液体が供給されてから長時間が経過している場合は、 タンク内の液体の温度と振動子の周辺温度とがほぼ等しくなっているので従来例 でも問題はないが、タンク内に振動子の周辺温度と異なる温度の液体を補給した 直後などでは、ホ−ンに供給される液体によってホ−ンの温度が変化し、振動子 の周辺温度に基づいて制御された振幅では安定した散布形態を形成することがで きないという欠点があった。 However, it was found by the applicant's post-study that the temperature change of the amplitude is more dependent on the temperature of the liquid supplied to the horn than on the ambient temperature of the oscillator. In other words, if a long time has passed since the liquid was supplied to the tank, the temperature of the liquid in the tank and the ambient temperature of the vibrator are almost the same, so there is no problem even in the conventional example, but the tank Immediately after replenishing a liquid with a temperature different from the ambient temperature of the vibrator, the temperature of the horn changes due to the liquid supplied to the horn, and the amplitude controlled based on the ambient temperature of the vibrator is There was a drawback that it was not possible to form a stable spray form.

An object is to provide an ultrasonic atomizer that can be used.

The horn accommodating portion 6a is formed in a substantially cylindrical shape, and the bottom surface of the horn accommodating portion 6a forms an inclined surface that becomes lower toward the center, and the tip end side of the horn 4 penetrates through the center portion of the bottom surface.

A washer 8 is attached to each screw 7, and one end of each washer 8 is inserted into the annular groove 4 a of the horn 4. As a result, the flange portion 4b is sandwiched between one end of each washer 8 and the step portion 6f, and the liquid reservoir holder 6 is assembled to the horn 4.

【００１４】 ９はホ−ン４に消毒液を供給するポンプで、その吐出パイプ９ａの先端を液溜 ホルダ６の側面に貫入され、その吸入パイプ９ｂを消毒液貯蔵用のタンク１０に 接続されている。Reference numeral 9 is a pump for supplying the disinfectant solution to the horn 4, the tip of its discharge pipe 9a is penetrated into the side surface of the liquid reservoir holder 6, and its suction pipe 9b is connected to the tank 10 for storing the disinfectant solution. ing.
【００１５】 １１はタンク１０内の消毒液の温度を検出する温度センサで、後記する振幅制 御部１２に接続されている。Reference numeral 11 denotes a temperature sensor that detects the temperature of the disinfecting liquid in the tank 10, and is connected to an amplitude control unit 12 described later.
【００１６】 １２はマイクロコンピュ−タ構成の振幅制御部で、前記定電流回路３ａ及び温 度センサ１１に接続されている。この振幅制御部１２は、二つの境界温度Ｔ1 （ ５℃）及びＴ2 （１０℃）と、各境界温度Ｔ1 ，Ｔ2 によって区画される各温度 範囲、Ｔ1 以下、Ｔ1 〜Ｔ2 及びＴ2 以上にそれぞれ対応する電流値Ｉ1 ，Ｉ2 及びＩ3 を設定しており、温度センサ１１の検出温度ｔ及び後記するプログラム に基づいて定電流回路３ａの電流値Ｉを変え、振動子１の振幅を制御するように なっている。尚、電流値Ｉ1 ，Ｉ2 及びＩ3 は、前記各温度範囲において振動子 １の振動の振幅が適正となる値に実験的に決めてあり、Ｉ1 ＞Ｉ2 ＞Ｉ3 の関係 になっている。Reference numeral 12 denotes an amplitude control unit having a micro computer configuration, which is connected to the constant current circuit 3 a and the temperature sensor 11. The amplitude control unit 12 includes two boundary temperatures T 1 (5 ° C.) and T 2 (10 ° C.) and temperature ranges divided by the boundary temperatures T 1 and T 2 , T 1 or less, T 1 to T 1.

The current values I 1 , I 2 and I 3 have been experimentally determined to be values at which the vibration amplitude of the vibrator 1 is appropriate in each of the above temperature ranges, and have a relationship of I 1 > I 2 > I 3 . Is becoming
【００１７】 以上のように構成された超音波式霧化装置においては、発振回路２に電源３か ら電力が供給されると、振動子１に発振回路２から所定の高周波信号が印加され 、振動子１で発生した振動はホ−ン４によってその振幅を拡大され先端の振動出 力部４ｃから出力される。この時、ホ−ン４には振動の節及び腹がホ−ン４の軸 心方向に交互に現れ、振動出力部４ｃは振幅の最も大きな腹に対応している。In the ultrasonic atomization device configured as described above, when power is supplied from the power supply 3 to the oscillation circuit 2, a predetermined high frequency signal is applied from the oscillation circuit 2 to the vibrator 1. The vibration generated by the vibrator 1 has its amplitude expanded by the horn 4, and is output from the vibration output unit 4c at the tip. At this time, vibration nodes and antinodes alternately appear in the horn 4 in the axial direction of the horn 4, and the vibration output section 4c corresponds to the antinode having the largest amplitude.
【００１８】 この振動状態で吐出パイプ９ａから液溜ホルダ６内に消毒液が供給されると、 該消毒液はホ−ン４の周囲に一旦溜り、各流出口６ｃから徐々に流出する。また 、流出した消毒液は振動出力部４ｃに到達し、振動出力部４ｃに接触すると同時 に霧化される。この時、各流出口６ｃから流出する消毒液は毛管現象の作用によ って突部６ｄとホ−ン４との間に案内されるとともに、各流出口６ａはホ−ン４ を挟んだ両側に位置していることから、振動出力部４ｃには各流出口６ｃに対応 する箇所に集中的に消毒液が供給される。これにより、霧化された消毒液Ａの飛 散方向に指向性が生じ、図５及び図６に示すように横方向に広がりを持つ散布形 態が形成されることとなる。When the disinfectant liquid is supplied from the discharge pipe 9a into the liquid reservoir holder 6 in this vibrating state, the disinfectant liquid temporarily accumulates around the horn 4 and gradually flows out from each outlet 6c. Further, the disinfecting liquid that has flown out reaches the vibration output unit 4c and is atomized at the same time when it contacts the vibration output unit 4c. At this time, the disinfecting liquid flowing out from each outlet 6c is guided between the protrusion 6d and the horn 4 by the action of the capillary action, and each outlet 6a sandwiches the horn 4 between them. Since they are located on both sides, the vibration output part 4c is supplied with the disinfectant solution at a location corresponding to each outlet 6c. As a result, directivity is generated in the direction of the atomized disinfectant solution A to be scattered, and a spraying pattern having a lateral spread is formed as shown in FIGS. 5 and 6.
【００１９】 次に、図７に示すフロ−チャ−トを参照して振幅制御部１２の動作を説明する 。Next, the operation of the amplitude controller 12 will be described with reference to the flowchart shown in FIG.
【００２０】 まず、温度センサ１１の検出温度ｔが境界温度Ｔ1 を下回っていれば（Ｓ１） 、定電流回路３ａの電流値ＩをＩ1 とする（Ｓ２）。この後、検出温度ｔが境界 温度Ｔ1 以上になるか（Ｓ３）、或いは前記ステップＳ１において検出温度ｔが 境界温度Ｔ1 以上であると判別され、検出温度ｔが境界温度Ｔ2 を下回っていれ ば（Ｓ４）、電流値ＩをＩ2 とする（Ｓ５）。この後、検出温度ｔが境界温度Ｔ2 以上になるか（Ｓ６，Ｓ７）、或いは前記ステップＳ４において検出温度ｔが 境界温度Ｔ1 以上であると判別されれば、電流値ＩをＩ3 とする（Ｓ８）。この 後、検出温度ｔが境界温度Ｔ2 を下回るか（Ｓ９）、或いは前記ステップＳ７に おいて検出温度ｔが境界温度Ｔ2 を下回っていれば、再びステップＳ１に戻る。 これにより、定電流回路３ａの電流値Ｉは検出温度ｔに伴って図８に示すように 変化する。即ち、電流値Ｉは検出温度ｔが下がるに従って大きくなる。First, if the detected temperature t of the temperature sensor 11 is lower than the boundary temperature T 1 (S1), the current value I of the constant current circuit 3a is set to I 1 (S2). Thereafter, the detected temperature t becomes equal to or higher than the boundary temperature T 1 (S3), or it is determined in step S1 that the detected temperature t is equal to or higher than the boundary temperature T 1 , and the detected temperature t is lower than the boundary temperature T 2. if Re (S4), the current value I and I 2 (S5). After that, if the detected temperature t becomes the boundary temperature T 2 or more (S6, S7), or if it is determined that the detected temperature t is the boundary temperature T 1 or more in step S4, the current value I is set to I 3 . Yes (S8). After this, if the detected temperature t is lower than the boundary temperature T 2 (S9), or Oite detected temperature t in the step S7 if below the boundary temperature T 2, returns to step S1. As a result, the current value I of the constant current circuit 3a changes with the detected temperature t as shown in FIG. That is, the current value I increases as the detected temperature t decreases.
【００２１】 また、振動子１の振動の振幅は検出温度ｔに伴って図９に示すように変化する 。即ち、振動子１の振幅は検出温度ｔが常温から低温に下がるに従って大きくな り、図中破線で示した消毒液の霧化に必要な最小振幅曲線Ａとほぼ一致する特性 曲線Ｂを描く。Further, the amplitude of vibration of the vibrator 1 changes as shown in FIG. 9 with the detected temperature t. That is, the amplitude of the vibrator 1 increases as the detected temperature t decreases from room temperature to a low temperature, and a characteristic curve B is drawn which substantially coincides with the minimum amplitude curve A required for atomizing the disinfectant solution shown by the broken line in the figure.
【００２２】 このように、本実施例の超音波式霧化装置によれば、タンク１０内の消毒液の 温度を検出する温度センサ１１を設け、その検出温度ｔに基づいて振動子１の振 動の振幅を制御するようにしたので、振幅変化に依存性の高い消毒液の温度に応 じた振幅制御が行われ、ホ−ン４に供給される消毒液と振動子１の周辺温度が異 なっても、常に安定した散布形態を形成することができる。As described above, according to the ultrasonic atomizing apparatus of the present embodiment, the temperature sensor 11 that detects the temperature of the disinfectant solution in the tank 10 is provided, and the vibrator 1 vibrates based on the detected temperature t. Since the amplitude of the motion is controlled, the amplitude control is performed according to the temperature of the disinfectant solution, which is highly dependent on the amplitude change, and the disinfectant solution supplied to the horn 4 and the ambient temperature of the vibrator 1 are controlled. Even if different, it is possible to always form a stable spray form.
【００２３】 尚、前記実施例では液溜ホルダ６を備えた超音波式霧化装置を示したが、液溜 ホルダ６を備えず、ノズルから直接ホ−ンに消毒液を射出するタイプのものであ っても前記効果を得ることができる。また、前記実施例では、複数の温度範囲を 設定することにより、振動子１の振幅を段階的に変える制御例を示したが、振動 子１に振幅測定装置を設け、この振幅測定装置の測定値に基づいて定電流回路３ ａの電流値をフィ−ドバック制御するようにしてもよい。更に、温度センサ１１ は、前記実施例のように消毒液の温度を直接検出するようにしてもよいが、タン ク１０の外壁等に取付け、消毒液の周辺温度を検出するようにしてもよいことは 勿論である。Although the ultrasonic atomizer provided with the liquid reservoir holder 6 is shown in the above embodiment, the ultrasonic atomizer is not provided with the liquid reservoir holder 6 and the disinfectant liquid is directly ejected from the nozzle to the horn. Even in this case, the above effect can be obtained. Further, in the above-described embodiment, the control example in which the amplitude of the vibrator 1 is changed stepwise by setting a plurality of temperature ranges has been shown. However, an amplitude measuring device is provided in the vibrator 1 to measure the amplitude. The current value of the constant current circuit 3a may be feedback-controlled based on the value. Further, the temperature sensor 11 may directly detect the temperature of the disinfectant solution as in the above embodiment, but may be attached to the outer wall of the tank 10 or the like to detect the ambient temperature of the disinfectant solution. Of course.
【００２４】 図１０及び図１１は本考案の他の実施例を示すもので、振動子１の振幅を制御 せずに、電磁ポンプ８の流量を制御するようにしたものである。即ち、前記定電 流回路３ａ及び振幅制御部１２の代りに、前記ポンプ９及び温度センサ１１に接 続する流量制御部１３を設けている。この流量制御部１３は、前記境界温度Ｔ1 ，Ｔ2 と、各境界温度Ｔ1 ，Ｔ2 によって区画される各温度範囲、Ｔ1 以下、Ｔ1 〜Ｔ2 及びＴ2 以上にそれぞれ対応する流量Ｑ1 ，Ｑ2 及びＱ3 を設定してお り、温度センサ１１の検出温度ｔ基づいてポンプ９の流量を変えるようになって いる。尚、流量Ｑ1 ，Ｑ2 及びＱ3 は、前記各温度範囲において振動子１の振動 の振幅に体して適量となる値に実験的に決めてあり、Ｑ1 ＜Ｑ2 ＜Ｑ3 の関係に なっている。また、流量制御部１３のプログラムについては前記振幅制御部１２ と基本的に同様であるため説明を省略する。10 and 11 show another embodiment of the present invention in which the flow rate of the electromagnetic pump 8 is controlled without controlling the amplitude of the vibrator 1. That is, instead of the constant current circuit 3a and the amplitude control section 12, a flow rate control section 13 connected to the pump 9 and the temperature sensor 11 is provided. The flow rate control unit 13 corresponds to the boundary temperatures T 1 and T 2 and temperature ranges divided by the boundary temperatures T 1 and T 2 , T 1 or less, T 1 to T 2 and T 2 or more, respectively. The flow rates Q 1 , Q 2 and Q 3 are set, and the flow rate of the pump 9 is changed based on the temperature t detected by the temperature sensor 11. It should be noted that the flow rates Q 1 , Q 2 and Q 3 are experimentally determined to be values that are suitable for the amplitude of the vibration of the vibrator 1 in each of the above temperature ranges, and Q 1 <Q 2 <Q 3 Have a relationship. Further, the program of the flow rate control unit 13 is basically the same as that of the amplitude control unit 12, and therefore its explanation is omitted.
