がされていた。Structure of a conventional example and its problems A conventional atomizing pump of this type has a structure as shown in FIG. That is, electrode films 2a and 2b are formed on opposing smooth surfaces of the electric vibrator 1, and the electrode film 2b and the nozzle plate 3 are bonded with a fixing layer 4a such as an organic or inorganic adhesive or soft solder.
The connection was made through. Further, the other (back) surface of the nozzle plate 3 and the body 5 were bonded via a fixing layer 4b, which is the same as the above-mentioned adhesive or soft solder.

いた。 The electric vibrator 1 is a ceramic body whose main components are PbO, TiO 2 , ZrO 2 , etc., and has a ring shape with an opening in the center of the circle, and the electrode films 2 a and 2 b are made of thick films such as silver. A sintered body of conductive paste, a metal vapor deposition film, a metal plating film, etc. were used. The nozzle plate 3 is a metal plate processed into a disk shape with a thickness of about 50 μm, and a through hole (hole diameter of about 70 to 100 μm) for the nozzle hole 6 is formed in the center of the nozzle plate 3.
There were multiple locations. The body 5 is a cylindrical metal body, and has a support part 7 on the upper part for joining the nozzle plate 3, a loop-shaped side wall 8 on the outer periphery for positioning the nozzle plate 3 during assembly, and a support part 7.
A concave liquid chamber 9 is provided in the center of the liquid chamber 9.
From there, a pair of liquid passages 10 were provided in the left and right direction.
電極膜２ａは、外部リード線接続用電極であ

これらの点は、動作時の電気振動子１からの振動
伝播を不安定にする原因となり、ノズル板３の共
振動作を不安定にするという欠点を有していた。 In this configuration, since the bonding interface between the nozzle plate 3 and the body 5 is wide, gas from the adhesive or flux during soft brazing tends to remain in the fixed layer 4b and near the interface during bonding, causing air bubbles. There was a problem of forming it. Furthermore, there is a problem in that excess adhesive or soft solder flows out from the bonding interface into the liquid chamber 9, causing the bonded end to fluctuate.
These points cause the vibration propagation from the electric vibrator 1 to become unstable during operation, and have the drawback of making the resonant operation of the nozzle plate 3 unstable.

定にする。Structure of the Invention In order to achieve this object, the present invention provides a plurality of through holes or cutting grooves in the portion of the body that contacts the outer peripheral end of the nozzle plate. With this configuration, during bonding, gaseous substances and liquid substances such as excess adhesive and soft solder at the bonding interface are discharged from the bonding interface through the through holes or cutting grooves.
Therefore, the bonding interface is dense with few bubbles,
Moreover, the outflow of adhesive and the like from the joint end is suppressed, and vibration propagation from the electric vibrator is stabilized.

A support part 7 for joining the nozzle plate 3 is provided, and an annular side wall 8 for positioning the nozzle plate 3 during assembly is provided on the outer periphery thereof with an inner diameter approximately the same as the diameter of the nozzle plate 3. In addition, in the portion of the side wall 8 that is in contact with the outer peripheral end of the nozzle plate 3, there are thin through holes 11 or cutting grooves 12 as shown in FIGS. 3A and 3B.
Further, a circular concave liquid chamber 9 is provided in the center of the support portion 7, and a pair of liquid passages 10 are provided from the liquid chamber 9 in the left and right direction.

利点もある。 In the above configuration, since the through hole 11 or the cutting groove 12 is provided in the part where the body 5 contacts the outer peripheral end of the nozzle plate 3, gaseous substances and excess adhesive during bonding are absorbed through these holes 11. It is discharged from the bonding interface via the grooves 12 and the grooves 12. Therefore, the bonding interface should be a dense layer with few bubbles,
Furthermore, there is no problem that the bonded end portion fluctuates due to outflow of adhesive or the like. As a result, during operation, vibration propagation from the electric vibrator 1 can be stabilized, and the resonance operation of the nozzle plate 3 can be stabilized. Furthermore, by reducing the number of bubbles, there is an advantage that reliability such as mechanical strength of the joint can be improved.

Therefore, the bonding interface becomes a dense layer, and the fluctuation of the bonding edge due to adhesive leakage is reduced, so during operation, the vibration propagation from the electric vibrator becomes stable, and the resonant operation of the nozzle plate becomes stable. The effect of doing so can be obtained.
