Description

本発明は、多数列に装着した圧電体振動子に円錐状ノズルを装着し、圧電体振動子を駆動して、ノズルから噴出した霧化粒子を回収して分溜する超音波霧化分溜装置に関するものである。   The present invention provides an ultrasonic atomization fractionation device in which a conical nozzle is attached to a piezoelectric vibrator mounted in multiple rows, and the piezoelectric vibrator is driven to collect and collect atomized particles ejected from the nozzle. It relates to the device.

この種の超音波霧化装置としては、図3に示すように、ケース1の側壁1aの上部に送風口1bを形成し、側壁1aの対向する側壁1cに吸引口1dを形成し、ケース1の底部に水平部1eより僅かに傾斜した複数の傾斜部1fを形成し、この傾斜部1fの下部にそれぞれ圧電体振動子2を装着し、又、傾斜部1fにそれぞれ圧電体振動子2より小径の孔1gを形成し、傾斜部1fの上部に、それぞれの傾斜と同方向に傾斜した円錐状のノズル3を装着し、さらに、ノズル3の上端より僅かに下側まで霧化液体4が常に一定のレベルになるように供給され、又、圧電体振動子2に発振器5から発振出力を印加したものを本出願人が提案している。   As shown in FIG. 3, this type of ultrasonic atomizer includes an air blowing port 1 b formed on the upper portion of the side wall 1 a of the case 1 and a suction port 1 d formed on the side wall 1 c facing the side wall 1 a. A plurality of inclined portions 1f that are slightly inclined from the horizontal portion 1e are formed at the bottom of each, and the piezoelectric vibrators 2 are respectively attached to the lower portions of the inclined portions 1f. A small-diameter hole 1g is formed, and a conical nozzle 3 inclined in the same direction as each inclination is mounted on the upper part of the inclined portion 1f. Further, the atomized liquid 4 is slightly below the upper end of the nozzle 3. The present applicant proposes that the piezoelectric vibrator 2 is supplied with an oscillation output from the oscillator 5 so as to be always at a constant level.

このように構成された従来の超音波霧化装置では、発振器から圧電体振動子2に発振出力が供給されると、圧電体振動子2から超音波が発生し、ノズル3と傾斜部1fの間に形成された霧化液体注入口3aから注入された霧化液体はノズル3から噴出して、霧化粒子4aが発生し、この霧化粒子4aは送風口1bから供給された送風によって吸引口1dから吸引され、図示しない回収装置によって回収される。 In the conventional ultrasonic atomizing apparatus configured as described above, when an oscillation output is supplied from the oscillator 5 to the piezoelectric vibrator 2, ultrasonic waves are generated from the piezoelectric vibrator 2, and the nozzle 3 and the inclined portion 1f. The atomized liquid 4 injected from the atomized liquid injection port 3a formed between the nozzles 3 is ejected from the nozzle 3 to generate atomized particles 4a. The atomized particles 4a are blown air supplied from the blower port 1b. Is sucked from the suction port 1d and collected by a collecting device (not shown).

しかしながら、このように従来の超音波霧化装置では、ケース1内に多数の圧電体振動子2及びノズル3を装着した場合、隣り合った圧電体振動子2とノズル3の間隔が狭いため、送風口1b側のノズル3から噴出された霧化粒子が次のノズル3から発生した霧化粒子と衝突して、霧化粒子の径が大きくなり、吸引口1dから排出されないで、霧化液体5の液面に落下したり、側壁1cに衝突して、吸引口1dから排出される霧化粒子が少なくなり、霧化効率がわるいという問題があり、又、ケース内が湿度飽和状態になり、それ以上霧化量が増えないという問題があった。
特願2004−320631
However, in the conventional ultrasonic atomizer, when a large number of piezoelectric vibrators 2 and nozzles 3 are mounted in the case 1, the distance between the adjacent piezoelectric vibrators 2 and nozzles 3 is narrow. The atomized particles ejected from the nozzle 3 on the air blowing port 1b side collide with the atomized particles generated from the next nozzle 3, the diameter of the atomized particles increases, and the atomized liquid is not discharged from the suction port 1d. 5 drops to the liquid level or collides with the side wall 1c, and there is a problem that atomization particles discharged from the suction port 1d decrease, resulting in poor atomization efficiency, and the inside of the case becomes saturated with humidity. There was a problem that the amount of atomization did not increase any more.
Japanese Patent Application No. 2004-320631

解決しようとする問題点は、提案された超音波霧化装置では、ケース内に圧電体振動子及びノズルを多数装着してるため、隣り合ったノズルから発生した霧化粒子が互いに干渉して液面に落下したり、側壁に衝突して落下し、吸引口から排出される霧化粒子が少なく、霧化効率が非常に悪いという問題があり、ケース内が湿度飽和状態となり、それ以上霧化量が増えないという問題があった。   The problem to be solved is that in the proposed ultrasonic atomizer, a large number of piezoelectric vibrators and nozzles are mounted in the case, so that the atomized particles generated from the adjacent nozzles interfere with each other and are liquid. There is a problem that the atomization particles fall on the surface or collide with the side wall and are discharged from the suction port, and the atomization efficiency is very poor. There was a problem that the amount did not increase.

本発明では、ケースの一端に該ケースとほぼ同じ幅の送風口を形成し、他端に前記ケースとほぼ同じ幅の吸引口を形成し、送風口と吸引口の間に形成したケースの支持板に、送風口から吸引口の方向に僅かに傾斜したノズルをそれぞれ装着した多数の圧電体振動子を多数列装着し、かつ常に前記ケースの支持板の上からノズルの上端より僅か下方のレベルになるように霧化液体供給口から霧化液体を供給し、ノズル及び圧電体振動子の隣り合った列を遮断するように、霧化液体の上方において、ノズル及び圧電体振動子の隣り合った列の間にそれぞれ仕切板を装着し、送風口から送風する気体はノズルの上端より上方を通過し、仕切板の間を通って上方に送風するものである。   In the present invention, the case is formed between the blower port and the suction port by forming a blower port having the same width as the case at one end of the case, and forming a suction port having the same width as the case at the other end. A large number of piezoelectric vibrators, each mounted with a nozzle slightly inclined in the direction from the air blowing port to the suction port, are mounted on the plate, and the level is always slightly above the upper end of the nozzle from above the support plate of the case. The atomizing liquid is supplied from the atomizing liquid supply port so that the nozzle and the piezoelectric vibrator are adjacent to each other above the atomizing liquid so as to block the adjacent rows of the nozzle and the piezoelectric vibrator. A partition plate is mounted between the rows, and the gas blown from the blower port passes above the upper end of the nozzle and blows upward through the partition plate.

本発明の超音波霧化分溜装置では、送風口をケースの幅とほぼ同じ幅に設け、ケースの支持板に装着した多数列の圧電体振動子とノズルの間にそれぞれ仕切板を装着することにより、隣り合ったノズルから発生する霧化粒子が干渉することなく送風され、ケースの支持板に装着した多数列の圧電体振動子とノズルを1列毎に1つ分だけずらして装着することにより、隣り合った列のノズルから発生した霧化粒子が違いに干渉することなく排出されるという利点がある。   In the ultrasonic atomization fractionating apparatus of the present invention, the air blowing port is provided with a width substantially the same as the width of the case, and the partition plates are respectively mounted between the multiple rows of piezoelectric vibrators mounted on the support plate of the case and the nozzles. As a result, the atomized particles generated from the adjacent nozzles are blown without interference, and the multiple rows of piezoelectric vibrators and nozzles mounted on the support plate of the case are shifted by one by one for each row. Thus, there is an advantage that the atomized particles generated from the nozzles in the adjacent rows are discharged without interfering with the difference.

本発明では、ケースの一端に該ケースとほぼ同じ幅の送風口を形成し、他端に前記ケースとほぼ同じ幅の吸引口を形成し、送風口と吸引口の間に形成したケースの支持板に、送風口から吸引口の方向に僅かに傾斜したノズルをそれぞれ装着した多数の圧電体振動子を多数列装着し、1つの列のノズルを装着した多数の圧電体振動子が隣り合った列の多数の圧電体振動子の間に位置するように構成し、常に前記ケースの支持板の上からノズルの上端より僅か下方のレベルになるように霧化液体供給口から霧化液体を供給し、ノズル及び圧電体振動子の隣り合った列をそれぞれ遮断するように、霧化液体の上方で、ノズル及び圧電体振動子の隣り合った列の間にそれぞれ仕切板を装着し、送風口から送風する気体はノズルの上端より上方を通過し、仕切板の間を通って上方に送風するものである。   In the present invention, the case is formed between the blower port and the suction port by forming a blower port having the same width as the case at one end of the case, and forming a suction port having the same width as the case at the other end. A large number of piezoelectric vibrators each mounted with a nozzle slightly inclined in the direction from the air blowing port to the suction port are mounted on the plate, and a large number of piezoelectric vibrators mounted with one row of nozzles are adjacent to each other. The atomizing liquid is supplied from the atomizing liquid supply port so as to be positioned between a large number of piezoelectric vibrators in a row and always at a level slightly above the upper end of the nozzle from above the support plate of the case. A partition plate is mounted between the adjacent rows of the nozzle and the piezoelectric vibrator above the atomizing liquid so as to block the adjacent rows of the nozzle and the piezoelectric vibrator, respectively. The gas blown from above passes above the upper end of the nozzle It is intended to blow upwardly through the partition plates.

Inclined portions 12a are formed, and the piezoelectric vibrators 14 having the nozzles 13 attached thereto are attached to the inclined portions 12a. The piezoelectric vibrators 14 to which the nozzles 13 are attached are attached in multiple rows, and are adjacent to each other. In the row, only one piezoelectric vibrator 14 equipped with the nozzle 13 is attached to each other. In addition, the atomizing liquid 16 is supplied from the atomizing liquid supply device 15 through the supply port 15 a provided in the case 6, and the atomizing liquid 16 is always slightly below the upper end of the nozzle 13. Furthermore, an oscillation output is applied to the piezoelectric vibrator 14 from the oscillator 17 mounted below the support plate 12, and the piezoelectric mounted on the nozzle 13 above the liquid level of the atomized liquid 16.
