Title:
液体ディスペンサーとその流量調整方法
Document Type and Number:
Japanese Patent JP7369644
Kind Code:
B2
Abstract:
To provide a liquid dispenser that is able to reduce and stabilize the volume of a droplet caused to fall in drip discharge.SOLUTION: A liquid dispenser 10 that discharges liquid includes: a nozzle 16 that discharges liquid; a pipe 15 that is supplied with liquid from a supply source and communicates with the nozzle 16; an electromagnetic valve 13 that is provided in the pipe 15 and can control opening/closing and an opening degree (or a flow rate ratio); and a control unit 20 that controls the electromagnetic valve 13. The control unit 20 executes control such that, when liquid is dripped from the nozzle 16 one droplet at a time, a signal used for opening the electromagnetic valve 13 at a predetermined opening degree (flow rate ratio) is output to the electromagnetic valve 13 for a predetermined time. The predetermined opening degree (flow rate ratio) is an opening degree (flow rate ratio) at which liquid continuously flows out of the nozzle 16 when the electromagnetic valve 13 is opened continuously at the opening degree (flow rate ratio).SELECTED DRAWING: Figure 1
