Nebulizer and chemical atomization method

A nebulizer comprising:

• a compressor including a shading motor as a power source and being provided with a discharge port configured to discharge compressed air generated by driving the shading motor;
• a nozzle configured to inject the compressed air generated by the compressor;
• an atomization unit including a baffle disposed so as to face the nozzle, and being configured to generate an aerosol by adding a chemical solution to the compressed air injected from the nozzle and spraying the compressed air added with the chemical solution onto the baffle;
• and
• a flow path connecting the discharge port and the nozzle, wherein
• the shading motor includes a rotor and a stator, the stator being made of a soft magnetic material and having an apparent volume of 78000 mm3 or less, and
• the nebulizer further includes a load reduction mechanism configured to reduce a load applied to the shading motor by suppressing a pressure increase in the flow path over a period from a first time point at which the shading motor starts driving to a second time point at which a rotation speed of the rotor reaches a predetermined rotation speed.
