Description
本発明は、液体噴射式洗浄機、詳しくは洗浄液中に超音波を伝搬させて、そのエネルギーによって洗浄液をノズルから噴射させて洗浄する超音波による液体噴射式洗浄機に関する。 The present invention relates to a liquid-jet cleaning machine, and more particularly, to an ultrasonic liquid-jet cleaning machine in which ultrasonic waves are propagated in a cleaning liquid and cleaning is performed by spraying a cleaning liquid from a nozzle using the energy.
従来の超音波による液体噴射式洗浄機は例えば、基板等、電子部品や精密機器などの洗浄に用いられるもので、液体噴射式洗浄機は図３に示すように重力方向の下向きに固定されたノズル（１）と、ノズル（１）の噴射口（１１）と対向する閉塞部に装着された振動子（２）と、ノズル（１）内に液体を供給する供給配管（３）を接続する供給口（１０）と対向する側面に液体の過多量又は液中の気泡を排出する排出配管（４）を接続する排出口（１２）とをノズル（１）に備える。また、振動子（２）より下部の液体が上部のケーブル（８）の方に漏れなくする遮蔽部材（５）とで構成されている。 Conventional ultrasonic liquid jet cleaning machines are used for cleaning electronic components and precision instruments such as substrates, for example, and the liquid jet cleaning machine is fixed downward in the direction of gravity as shown in FIG. The nozzle (1), the vibrator (2) attached to the closing portion facing the injection port (11) of the nozzle (1), and the supply pipe (3) for supplying liquid into the nozzle (1) are connected. The nozzle (1) is provided with a discharge port (12) connected to a discharge pipe (4) for discharging an excessive amount of liquid or bubbles in the liquid on a side surface facing the supply port (10). Further, it is constituted by a shielding member (5) that prevents liquid below the vibrator (2) from leaking toward the upper cable (8).
その排出配管（４）の排出口（１２）の位置を振動子（２）の接液面（２a）と同じ又はそれより高くしているので、液中の気泡は浮力によって排出口（１２）より排出される。供給配管（３）からノズル（１）の中に供給された液体は振動子（２）の励振と共に重力以上に加速して洗浄対象物（９）に向かって噴射する。従って、液体噴射式洗浄機の場合、液体に超音波を有効に作用させ洗浄能力を十分に発揮させるためには、励振時に振動子（２）の接液面（２a）は液体に常に接していなければならない。もし、接液面（２a）が液体に接していない状態で振動子（２）を励振させると、洗浄能力を発揮できないばかりか、振動子が空励振状態となって寿命を縮める。また空励振状態を続けると振動子（２）が破損する等の問題があった。 Since the position of the discharge port (12) of the discharge pipe (4) is the same as or higher than the liquid contact surface (2a) of the vibrator (2), the bubbles in the liquid are discharged by the buoyancy. More discharged. The liquid supplied into the nozzle (1) from the supply pipe (3) is accelerated above the gravity with the vibration of the vibrator (2) and sprayed toward the cleaning object (9). Therefore, in the case of a liquid jet cleaning machine, the liquid contact surface (2a) of the vibrator (2) is always in contact with the liquid at the time of excitation in order to effectively apply ultrasonic waves to the liquid and sufficiently exhibit the cleaning ability. There must be. If the vibrator (2) is excited in a state where the liquid contact surface (2a) is not in contact with the liquid, the cleaning ability cannot be exhibited, and the vibrator becomes idle and shortens its life. Further, when the idling state is continued, there is a problem that the vibrator (2) is damaged.
しかし、供給配管（３）内に残留している気泡だけでなく、薬剤の混合により気泡が発生しやすい液体、たとえば NH４OH(アンモニア) ＋H２O２（過酸化水素) ＋ H２O(純水)とかHCＬ(塩素) ＋H２O２（過酸化水素) ＋ H２O(純水)等の過酸化水素（H２O２）等は常に気泡を発生しやすいので排出口（１２）に誘導する必要がある。又は洗浄対象物（９）に対して直角方向で洗浄している時、過渡的に気泡が多く発生した時に接液面（２a）上の気泡が一時待機する場所がないため接液面（２a）上に滞留するので、排出口（１２）に誘導する為に排出口（１２）の穴径を大きくして気泡を容易に誘導するのも良いが、薬剤の混合液体を必要以上に放出するのはＰＲＴＲ法の対象となる特定化学物質の削減を鑑みると好ましくない。また、排出口（１２）は絞られているので既定量の排出しか出来ないため、気泡が過渡的に多く発生しても一時待機できる場所がない。更にノズル（１）を（図２）の用に傾斜させての洗浄が出来ない問題がある。 However, not only bubbles remaining in the supply pipe (3), but also liquids that easily generate bubbles due to mixing of chemicals, such as NH4OH (ammonia) + H2O2 (hydrogen peroxide) + H2O (pure water) or HCL (chlorine) ) Hydrogen peroxide (H 2 O 2) such as + H 2 O 2 (hydrogen peroxide) + H 2 O (pure water) always tends to generate bubbles and must be guided to the discharge port (12). Alternatively, when cleaning is performed in a direction perpendicular to the object to be cleaned (9), there is no place where the bubbles on the liquid contact surface (2a) temporarily wait when a large number of bubbles are transiently generated. ) It stays on the top, so in order to guide to the discharge port (12), the hole diameter of the discharge port (12) may be increased to easily induce bubbles, but the mixed liquid of medicine is discharged more than necessary. This is not preferable in view of the reduction of specific chemical substances subject to the PRTR method. In addition, since the discharge port (12) is narrowed, only a predetermined amount can be discharged, so there is no place where it can stand by temporarily even if a large number of bubbles are generated transiently. In addition, there is a problem that the nozzle (1) cannot be cleaned by being inclined for (FIG. 2).
複数の薬剤を混合し、過渡的に気泡が多く発生する液体の場合、気泡が接液面（２a）に少しでも滞留すること無く排出するには、ノズル（１）の角度を今より傾斜させて気泡を排出するしかないが、その角度を変えることは洗浄の質や洗浄能力が変化するので好ましくない。従来の液体噴射式洗浄機の如く、洗浄対象物（９）に対してノズル（１）が直角方向になっているものでは、過渡的に気泡が多く発生した時に気泡の一時待機できる場所がないと言う問題が生じる。また任意の角度に傾斜して洗浄が出来ないと言った問題もある。それ故この発明の目的は、傾斜しての洗浄を可能にして振動子の破損を防止することができる超音波による液体噴射式洗浄機を提供する事を目的としている。 In the case of a liquid in which a plurality of chemicals are mixed and a large amount of bubbles are generated transiently, the nozzle (1) can be tilted more in order to discharge the bubbles without any stagnation on the liquid contact surface (2a). However, it is not preferable to change the angle because the quality of cleaning and the cleaning ability change. In the case where the nozzle (1) is perpendicular to the object to be cleaned (9) as in the conventional liquid jet type washing machine, there is no place where the bubbles can be temporarily held when many bubbles are generated transiently. The problem that occurs. There is also a problem that it cannot be cleaned at an arbitrary angle. Therefore, an object of the present invention is to provide a liquid jet cleaning machine using ultrasonic waves that can be washed while being tilted to prevent damage to the vibrator.
上記の目的を達成するために、請求項１の本発明は、供給口（１０）からノズル（１）内に供給された洗浄液に振動子（２）によって超音波を伝搬させてその洗浄液を噴射口（１１）から噴射させながら、洗浄液から発生した気泡を洗浄液の過多量と共に排出口（１２）から排出するように構成した液体噴射式洗浄機において、
ノズル（１）内に供給された洗浄液に振動子カバー（１４）の底板の接液面（２a）が接触する位置に設けた振動子カバー（１４）と、振動子カバー（１４）の底板の上面に設置した振動子（２）と、振動子カバー（１４）の側板とノズル内面との間に設けた溜り室（１３）と、振動子カバー（１４）の側板上部とノズル（１）内面との間に設けられノズル（１）内に供給された洗浄液と振動子（２）との接触を防止するためのシール部材（５）と、を備えることを特徴とする。
In order to achieve the above object, the present invention according to claim 1 is directed to injecting the cleaning liquid by propagating ultrasonic waves by the vibrator (2) to the cleaning liquid supplied from the supply port (10) into the nozzle (1). In the liquid jet cleaning machine configured to discharge air bubbles generated from the cleaning liquid from the discharge port (12) together with an excessive amount of the cleaning liquid while being jetted from the mouth (11),
The vibrator cover (14) provided at a position where the liquid contact surface (2a) of the bottom plate of the vibrator cover (14) contacts the cleaning liquid supplied into the nozzle (1), and the bottom plate of the vibrator cover (14). The vibrator (2) installed on the upper surface, the reservoir (13) provided between the side plate of the vibrator cover (14) and the inner surface of the nozzle, the upper part of the side plate of the vibrator cover (14), and the inner surface of the nozzle (1) And a seal member (5) for preventing contact between the cleaning liquid supplied into the nozzle (1) and the vibrator (2).
また、請求項２の本発明は、ノズル（１）内の排出口（１２）の少なくとも一部及び前記溜り室（１３）の少なくとも一部の位置を、前記ノズル（１）の最大傾斜可能角度で、振動子カバー（１４）の接液面（２a）より高くしたことを特徴とする。 Further, according to the present invention of claim 2, at least a part of the discharge port (12) in the nozzle (1) and a position of at least a part of the reservoir chamber (13) are set to a maximum tiltable angle of the nozzle (1). Thus, the height is higher than the liquid contact surface (2a) of the vibrator cover (14).
以上の説明から明らかなように、本説明にあっては次に列挙する効果が得られる。 As is clear from the above description, the effects listed below can be obtained in this description.
請求項１の方法では、図１に示す気泡が発生してもノズル（１）内の圧力が上昇して振動子カバー（１４）の底板の接液面（２a）上の気泡が浮力によって接液面（２a）に滞留すること無く溜り室（１３）に入り排出口（１２）から排出配管（４）より排出する。溜り室（１３）を設ける事により気泡を集められる一時待機する場所と成り気泡を排出口（１２）に誘導する溜り室（１３）とで構成されているので、振動子（２）の破損を防止する事ができる。 In the method of claim 1, even if the bubbles shown in FIG. 1 are generated, the pressure in the nozzle (1) rises and the bubbles on the liquid contact surface (2 a) of the bottom plate of the vibrator cover (14) are contacted by buoyancy. Without entering the liquid surface (2a), it enters the reservoir chamber (13) and is discharged from the discharge port (12) through the discharge pipe (4). By providing the reservoir chamber (13), the chamber (13) is a temporary standby place where bubbles can be collected and guides the bubbles to the discharge port (12). It can be prevented.
また、請求項２では、図２に示すノズル（１）の中に装着したU字型に成っている振動子カバー（１４）の下部に在る底板の接液面(２a)から排出口(１２)の上部位置の長さ（L）は任意に決める事ができるが、接液面(２a)から排出口(１２)の上部位置の長さ（L）によりノズルの中心と洗浄対象物（９）の垂線との角度βは接液面（２a）が排出口（１２）の上部位置を基点にして水平なA−Aの範囲内の傾きであれば振動子カバー(１４)の接液面(２a)に滞留することなく排出口（１２）の方に回り込み気泡が洗浄液と共に排出口（１２）から排出するため、ノズル（１）を傾斜する様に構成されているので、振動子（２）の破損を防止する事ができる。 Further, in claim 2, the discharge port (2a) is connected to the discharge port (2a) on the bottom plate of the U-shaped transducer cover (14) mounted in the nozzle (1) shown in FIG. Although the length (L) of the upper position of 12) can be arbitrarily determined, the center of the nozzle and the object to be cleaned (L) are determined by the length (L) of the upper position of the discharge port (12) from the liquid contact surface (2a). The angle β between the vertical line 9) and the wetted surface of the vibrator cover (14) if the wetted surface (2a) is inclined within the horizontal range AA with the upper position of the discharge port (12) as a base point. The nozzle (1) is configured to incline because the air bubbles wrap around toward the discharge port (12) without staying on the surface (2a) and discharge from the discharge port (12) together with the cleaning liquid. 2) can be prevented from being damaged.
以下、本発明の実施の形態を図に基づいて説明する。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
図１は、本発明の実施例１の断面図であって、薬剤等を混合した気泡が発生する液体は、図示しない供給タンクから送られ、供給配管（３）を通りノズル（１）の内に入ると噴射口（１１）から吐出するが、噴射口（１１）が絞られているのでノズル（１）内部の圧力が上昇するため、ノズル（１）を洗浄対象物（９）に対して直角にしても、また３６０度どの位置にした場合でも、接液面（２a）上の気泡が浮上して溜り室（１３）に入るので、溜り室（１３）は気泡を寄り集める一時待機場所と成りダンパー室の役目も果たす。また円筒状に構成しているので気泡は浮上して排出口（１２）の方に押し流され、絞られた排出口（１２）から気泡は液体と共に排出配管（４）を通り排出される。 FIG. 1 is a cross-sectional view of the first embodiment of the present invention, in which a liquid in which bubbles are mixed with a medicine or the like is sent from a supply tank (not shown), passes through a supply pipe (3), and enters the nozzle (1). When it enters, it discharges from the injection port (11), but since the injection port (11) is throttled, the pressure inside the nozzle (1) rises. Even if it is at a right angle and at any position of 360 degrees, the bubbles on the liquid contact surface (2a) float and enter the reservoir chamber (13), so the reservoir chamber (13) is a temporary standby place where bubbles are gathered together It also serves as a damper room. Further, since it is configured in a cylindrical shape, the bubbles rise and are pushed toward the discharge port (12), and the bubbles are discharged from the throttled discharge port (12) through the discharge pipe (4) together with the liquid.
図２では、ノズル（１）内の振動子カバー（１４）の底板の接液面（２a）から排出口（１２）の上部位置の長さ（L）を変えると傾けられる角度(β)も変わる。またノズル（１）の排出口（１２）の上部位置を基点にして接液面（２a）が傾いている上部の接点までの水平な線A−Aが振動子（２）を発振するのに必要となる最低液面で、これによりノズル（１）の傾く角度(β)が決まる。その傾きの角度(β)内であれば気泡が接液面（２a）に滞留せず浮上して溜り室（１３）の中で排出口（１２）の方に回り込み洗浄液と共に排出口（１２）から排出配管（４）より排出する。また、溜り室（１３）に気泡が過渡的により多く流れ溜り室（１３）からあふれて接液面（２a）に残留する場合は、長さ（L）を長く取るか、又は排出口（１２）の穴径を大きくして調節すると接液面（２a）に滞留せず排出口（１２）から気泡が洗浄液と共に排出配管（４）より排出することができる。 In FIG. 2, when the length (L) of the upper position of the discharge port (12) is changed from the liquid contact surface (2a) of the bottom plate of the vibrator cover (14) in the nozzle (1), the angle (β) tilted is also changed. change. In addition, a horizontal line AA from the upper position of the discharge port (12) of the nozzle (1) to the upper contact where the liquid contact surface (2a) is inclined causes the oscillator (2) to oscillate. This determines the angle (β) at which the nozzle (1) tilts at the minimum liquid level required. If the angle is within the inclination angle (β), the air bubbles do not stay on the liquid contact surface (2a) and rise to the inside of the reservoir chamber (13) toward the discharge port (12), together with the cleaning liquid, the discharge port (12). From the discharge pipe (4). Further, when more bubbles are transiently flowing into the reservoir chamber (13) and overflow from the reservoir chamber (13) and remain on the liquid contact surface (2a), the length (L) is increased or the discharge port (12 When the hole diameter is adjusted to be larger, bubbles do not stay on the liquid contact surface (2a) and bubbles can be discharged from the discharge port (12) through the discharge pipe (4) together with the cleaning liquid.

本発明は、液体噴射式洗浄機、詳しくは洗浄液中に超音波を伝搬させて、そのエネルギーによって洗浄液をノズルから噴射させて洗浄する超音波による液体噴射式洗浄機に関する。 The present invention relates to a liquid-jet cleaning machine, and more particularly, to an ultrasonic liquid-jet cleaning machine in which ultrasonic waves are propagated in a cleaning liquid and cleaning is performed by spraying a cleaning liquid from a nozzle using the energy.
従来の超音波による液体噴射式洗浄機は例えば、基板等、電子部品や精密機器などの洗浄に用いられるもので、液体噴射式洗浄機は図３に示すように重力方向の下向きに固定されたノズル（１）と、ノズル（１）の噴射口（１１）と対向する閉塞部に装着された振動子（２）と、ノズル（１）内に洗浄液を供給する供給配管（３）を接続する供給口（１０）と対向する側面に洗浄液の過多量又は液中の気泡を排出する排出配管（４）を接続する排出口（１２）とをノズル（１）に備える。また、振動子（２）より下部の洗浄液が上部のケーブル（８）の方に漏れなくするシール部材（５）とで構成されている。Conventional ultrasonic liquid jet cleaning machines are used for cleaning electronic components and precision instruments such as substrates, for example, and the liquid jet cleaning machine is fixed downward in the direction of gravity as shown in FIG. The nozzle (1), the vibrator (2) attached to the closing portion facing the injection port (11) of the nozzle (1), and the supply pipe (3) for supplying the cleaning liquid into the nozzle (1) are connected. The nozzle (1) is provided with a discharge port (12) connected to a discharge pipe (4) for discharging an excessive amount of cleaning liquid or bubbles in the liquid on the side surface facing the supply port (10). Further, the cleaning liquid below the vibrator (2) is constituted by a seal member (5) that prevents the upper cable (8) from leaking.
その排出配管（４）の排出口（１２）の位置を振動子（２）の接液面（２ａ）と同じ又はそれより高くしているので、液中の気泡は浮力によって排出口（１２）より排出される。供給配管（３）からノズル（１）の中に供給された洗浄液は振動子（２）の励振と共に重力以上に加速して洗浄対象物（９）に向かって噴射する。従って、液体噴射式洗浄機の場合、洗浄液に超音波を有効に作用させ洗浄能力を十分に発揮させるためには、励振時に振動子（２）の接液面（２ａ）は洗浄液に常に接していなければならない。もし、接液面（２ａ）が洗浄液に接していない状態で振動子（２）を励振させると、洗浄能力を発揮できないばかりか、振動子が空励振状態となって寿命を縮める。また空励振状態を続けると振動子（２）が破損する等の問題があった。 Since the position of the discharge port (12) of the discharge pipe (4) is the same as or higher than the liquid contact surface (2a) of the vibrator (2), the bubbles in the liquid are discharged by the buoyancy. More discharged. The cleaning liquid supplied from the supply pipe (3) into the nozzle (1) is accelerated above the gravity with the excitation of the vibrator (2) and sprayed toward the cleaning object (9). Therefore, in the case of a liquid jet type cleaning machine, in order to effectively apply ultrasonic waves to the cleaning liquid and to fully display the cleaning ability, the liquid contact surface (2a) of the vibrator (2) is always in contact with the cleaning liquid during excitation. There must be. If the vibrator (2) is excited in a state where the liquid contact surface (2a) is not in contact with the cleaning liquid, not only the cleaning ability can be exhibited, but also the vibrator is in an idle excitation state and the life is shortened. Further, when the idling state is continued, there is a problem that the vibrator (2) is damaged.
しかし、供給配管（３）内に残留している気泡だけでなく、薬剤の混合により気泡が発生しやすい洗浄液、たとえばＮＨ４ＯＨ（アンモニア）＋Ｈ２Ｏ２（過酸化水素）＋Ｈ２Ｏ（純水）とかＨＣｌ（塩素）＋Ｈ２Ｏ２（過酸化水素）＋Ｈ２Ｏ（純水）等の過酸化水素（Ｈ２Ｏ２）等は常に気泡を発生しやすいので排出口（１２）に誘導する必要がある。又は洗浄対象物（９）に対して直角方向で洗浄している時、過渡的に気泡が多く発生した時に接液面（２ａ）上の気泡が一時待機する場所がないため接液面（２ａ）上に滞留するので、排出口（１２）に誘導する為に排出口（１２）の穴径を大きくして気泡を容易に誘導するのも良いが、薬剤の混合洗浄液を必要以上に放出するのはＰＲＴＲ法の対象となる特定化学物質の削減を鑑みると好ましくない。また、排出口（１２）は絞られているので既定量の排出しか出来ないため、気泡が過渡的に多く発生しても一時待機できる場所がない。更にノズル（１）を（図２）の用に傾斜させての洗浄が出来ない問題がある。However, not only bubbles remaining in the supply pipe (3) but also a cleaning liquid in which bubbles are likely to be generated due to mixing of chemicals, for example, NH4OH (ammonia) + H2O2 (hydrogen peroxide) + H2O (pure water) or HCl (chlorine). Since hydrogen peroxide (H 2 O 2) such as + H 2 O 2 (hydrogen peroxide) + H 2 O (pure water) always tends to generate bubbles, it must be guided to the outlet (12). Alternatively, when cleaning is performed in a direction perpendicular to the object to be cleaned (9), there is no place where the bubbles on the liquid contact surface (2a) temporarily wait when a large number of bubbles are transiently generated. ) Stays above, so that it is possible to easily induce bubbles by enlarging the hole diameter of the discharge port (12) in order to guide to the discharge port (12). This is not preferable in view of the reduction of specific chemical substances subject to the PRTR method. In addition, since the discharge port (12) is narrowed, only a predetermined amount can be discharged, so there is no place where it can stand by temporarily even if a large number of bubbles are generated transiently. In addition, there is a problem that the nozzle (1) cannot be cleaned by being inclined for (FIG. 2).
複数の薬剤を混合し、過渡的に気泡が多く発生する洗浄液の場合、気泡が接液面（２ａ）に少しでも滞留すること無く排出するには、ノズル（１）の角度を今より傾斜させて気泡を排出するしかないが、その角度を変えることは洗浄の質や洗浄能力が変化するので好ましくない。従来の液体噴射式洗浄機の如く、洗浄対象物（９）に対してノズル（１）が直角方向になっているものでは、過渡的に気泡が多く発生した時に気泡の一時待機できる場所がないと言う問題が生じる。また任意の角度に傾斜して洗浄が出来ないと言った問題もある。それ故この発明の目的は、傾斜しての洗浄を可能にして振動子の破損を防止することができる超音波による液体噴射式洗浄機を提供する事を目的としている。In the case of a cleaning liquid in which a plurality of chemicals are mixed and a large amount of bubbles are generated transiently, the nozzle (1) can be tilted more in order to discharge the bubbles without any stagnation on the liquid contact surface (2a). However, it is not preferable to change the angle because the quality of cleaning and the cleaning ability change. In the case where the nozzle (1) is perpendicular to the object to be cleaned (9) as in the conventional liquid jet type washing machine, there is no place where the bubbles can be temporarily held when many bubbles are generated transiently. The problem that occurs. There is also a problem that it cannot be cleaned at an arbitrary angle. Therefore, an object of the present invention is to provide a liquid jet cleaning machine using ultrasonic waves that can be washed while being tilted to prevent damage to the vibrator.
上記の目的を達成するために、請求項１の本発明は、供給口（１０）からノズル（１）内に供給された洗浄液に振動子（２）によって超音波を伝搬させてその洗浄液を噴射口（１１）から噴射させながら、洗浄液から発生した気泡を洗浄液の過多量と共に排出口（１２）から排出するように構成した液体噴射式洗浄機において、ノズル（１）内に供給された洗浄液に振動子カバー（１４）の底板の接液面（２ａ）が接触する位置に設けた振動子カバー（１４）と、振動子カバー（１４）の底板の上面に設置した振動子（２）と、振動子カバー（１４）の側板とノズル内面との間に設けた溜り室（１３）と、振動子カバー（１４）の側板上部とノズル（１）内面との間に設けられノズル（１）内に供給された洗浄液と振動子（２）との接触を防止するためのシール部材（５）と、を備えることを特徴とする。In order to achieve the above object, the present invention according to claim 1 is directed to injecting the cleaning liquid by propagating ultrasonic waves by the vibrator (2) to the cleaning liquid supplied from the supply port (10) into the nozzle (1).

また、請求項２の本発明は、ノズル（１）内の排出口（１２）の少なくとも一部及び前記溜り室（１３）の少なくとも一部の位置を、前記ノズル（１）の最大傾斜可能角度で、振動子カバー（１４）の接液面（２ａ）より高くしたことを特徴とする。Further, according to the present invention of claim 2, at least a part of the discharge port (12) in the nozzle (1) and a position of at least a part of the reservoir chamber (13) are set to a maximum tiltable angle of the nozzle (1). Thus, the height is higher than the liquid contact surface (2a) of the vibrator cover (14).
以上の説明から明らかなように、本説明にあっては次に列挙する効果が得られる。 As is clear from the above description, the effects listed below can be obtained in this description.
請求項１の方法では、図１に示す気泡が発生してもノズル（１）内の圧力が上昇して振動子カバー（１４）の底板の接液面（２ａ）上の気泡が浮力によって接液面（２ａ）に滞留すること無く溜り室（１３）に入り排出口（１２）から排出配管（４）より排出する。溜り室（１３）を設ける事により気泡を集められる一時待機する場所と成り気泡を排出口（１２）に誘導する溜り室（１３）とで構成されているので、振動子（２）の破損を防止する事ができる。In the method of claim 1, even if the bubbles shown in FIG. 1 are generated, the pressure in the nozzle (1) rises and the bubbles on the liquid contact surface (2 a) of the bottom plate of the vibrator cover (14) are contacted by buoyancy.

In addition, a horizontal line AA from the upper position of the discharge port (12) of the nozzle (1) to the upper contact where the liquid contact surface (2a) is inclined oscillates the vibrator (2). This determines the angle of inclination (β) of the nozzle (1) at the minimum liquid level required. If the angle is within the inclination angle (β), the air bubbles do not stay on the liquid contact surface (2a) but rise to the inside of the reservoir chamber (13) toward the discharge port (12) and the cleaning solution together with the cleaning solution (12). From the discharge pipe (4). Further, when more bubbles are transiently overflowing in the reservoir chamber (13) and overflow from the reservoir chamber (13) and remain on the liquid contact surface (2a), the length (L) is increased or the discharge port (12 When the hole diameter is adjusted to be large, bubbles do not stay on the liquid contact surface (2a) and bubbles can be discharged from the discharge port (12) through the discharge pipe (4) together with the cleaning liquid.
