Abstract

An electrostatic atomizer (100) is provided with a spray electrode (1), a reference electrode (2), a current-controlling means (24), and a voltage-applying means (22). A voltage is applied between the spray electrode (1) and the reference electrode (2). The current-controlling means (24) controls the amount of current flowing through the reference electrode (2). The voltage-applying means (22) applies a voltage between the spray electrode (1) and the reference electrode (2) on the basis of the current controlled by the current-controlling means (24). The tip of the reference electrode (2) is shaped so as to have a specific radius of curvature.

Description

technical field [0001] The present invention relates to an electrostatic spray device excellent in spray stability. Background technique [0002] Conventionally, a spray device that sprays a liquid in a container from a nozzle has been used in a wide range of fields. As such a spray device, an electrostatic spray device that atomizes and sprays a liquid using electrohydrodynamics (EHD: Electro Hydrodynamics) is known. [0003] In the electrostatic spray device described above, an electric field is formed near the tip of the nozzle, and the liquid at the tip of the nozzle is atomized and sprayed by the electric field. Generally, in an electrostatic spray device, an electric field is formed between two electrodes (a needle and a capillary (corresponding to a nozzle)) by applying a voltage between them (for example, refer to Patent Documents 1 and 2). [0004] It is important to control the intensity of the electric field formed near the tip of the nozzle to perform desired s...
