Bottom 71 is substantially horizontally extended in the downside of longitudinal void 212.Also, container bottom 71 has the first circular hole up and down
81.The opening of the downside of first circular hole 81 is discharge opening 23 described above.
Damper 72 is configured in the top of container bottom 71.The material of damper 72 is for example using elasticity than jet element 28
Big resin.Also, damper 72 has the second circular hole 82 up and down.First circular hole 81 and the second circular hole 82 are in the axial direction
It interconnects.Also, in the present embodiment, around the first circular hole 81 and the second circular hole 82 in container bottom 71
There are gaps 84 between upper surface and damper 72.
Washer 73 configures on the top of damper 72.The material of washer 73 gold for example smaller than damper 72 using elasticity
Belong to.Also, washer 73 has third circular hole 83 up and down.First circular hole 81, the second circular hole 82 and third circular hole 83 it
Between interconnect in the axial direction.In the present embodiment, the opening of the upside of third circular hole 83 becomes the outlet 22 of liquor 9.
Outlet 22 is located at the lower section side end of longitudinal void 212.Also, discharge opening 23 described above is located on the lower than outlet 22
The position of side.
The base plate 27 of present embodiment has and is existed by the first circular hole 81, the second circular hole 82 and third circular hole 83 like this
Through hole 80 made of being connected in up and down direction.Through hole 80 penetrates through container bottom 71, damper 72 and pad along the vertical direction

Extra pulse voltage acts vibration generating mechanism 40.If, can be always by the voltage of pulse signal using pulse width modulation controlled
± V (pulse voltage) is set as the voltage rating of vibration generating mechanism 40.Therefore, with pass through the feelings of voltage modulated driving force
Condition is compared, and control circuit 500 can be simply formed.
In addition, the amplitude disposably obtained from piezoelectric element is smaller if vibration generating mechanism uses piezoelectric element, because
This needs the mechanism of the amplification amplitude.In contrast, the liquor device for discharging fixed 1 of present embodiment uses generation electromagnetic driving force
Driver is as vibration generating mechanism.Therefore, the amplitude ratio disposably obtained from vibration generating mechanism 40 uses piezoelectric element
Situation is big.Therefore, it is not necessary to which amplification mechanism is arranged between vibration generating mechanism 40 and pin 30.That is, the amplitude of pin 30 with
The amplitude of the vibration disposably generated by vibration generating mechanism 40 is roughly the same or less than that.Like this if omitting amplification machine
