点があった。In this configuration, since the bonding interface between the nozzle plate 3 and the body 5 is wide, the adhesive and the gas from the mild steel (such as 7 lux in the case of "j") tend to remain near the fixed layer 4b and its interface during bonding. There was a problem in that bubbles were formed.Furthermore, there was a problem in that excess adhesive waste or mild steel flowed out from the joint interface into the liquid chamber 9, causing the joint end to fluctuate.
これらの点は、動作時に電気振動子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。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.

する作用を有する。Structure of the Invention In order to achieve this object, the present invention provides an atomizing pump structure in which a plurality of through holes or cutting grooves are provided in a portion corresponding to the joint portion of the nozzle plate with the body. With this configuration, gaseous substances, excess adhesive, and liquid substances such as mild steel at the joint interface are discharged from the joint interface through the cut hole or the cutting groove. Therefore, the bonded area is dense with few bubbles, and the outflow of adhesive and the like from the bonded end is suppressed, which has the effect of stabilizing the propagation of vibrations from the electric vibrator.
