1. A nebulizer kit comprising:

  • an atomizer that generates an aerosol by atomizing a liquid and ejects the aerosol in a first direction; and

    a particle sorting route that is in communication with the atomizer, and sorts particles of the liquid included in the aerosol so as to adjust a particle diameter distribution of the particles of the aerosol, and thereafter guides the aerosol to a discharge port;

    whereinthe particle sorting route includes a first particle sorting route that extends in the first direction from the atomizer and has a uniform or substantially uniform cross-sectional area in the first direction, a second particle sorting route that is in communication with the first particle sorting route and includes an inner end wall that directly faces the atomizer and has a curvature that curves from the first direction toward a second direction, and a third particle sorting route that is in communication with the second particle sorting route and extends in a direction parallel or substantially parallel to the first direction in a state of being shifted in a direction perpendicular or substantially perpendicular to the first direction;

    the first particle sorting route guides the aerosol ejected from the atomizer in a direction equal or substantially equal to the first direction to the second particle sorting route in the first direction;

    the inner end wall of the second particle sorting route guides the aerosol in the second direction, which is inclined with respect to the first direction, such that particles, among the particles of the aerosol, that have a particle diameter of a certain value or more collide with and attach to the inner end wall; and

    the third particle sorting route has a cross-sectional area greater than an entire cross-sectional area of the second particle sorting route in the first direction, and allows the aerosol to flow to the discharge port, particles with the particle diameter of the certain value or more among the particles being attached to an inner wall thereof that is parallel or substantially parallel with the first direction and is inclined with respect to the second direction.
