In some embodiments, as shown in fig. 4 and 5, the atomizing nozzle 10 includes the housing 3 and the core 4, i.e., the atomizing nozzle 10 is composed of two members. Wherein, as shown in connection with fig. 2, the housing 3 has a cavity 31 therein, and the outlet channel 13 is located at a first end 32 of the housing 3 and communicates with the cavity 31; the core 4 is at least partially inserted into the cavity 31 from the second end 33 of the housing 3, i.e. the core 4 may be partially inserted into the cavity 31 from the second end 33 of the housing 3 or may be inserted into the cavity 31 entirely from the second end 33 of the housing 3. The liquid inlet channel 2 penetrates through the core body 4 along a first direction, the first direction is the L1 direction shown in fig. 2, and the second end 33 and the first end 32 are oppositely arranged along the first direction; wherein the mixing space 12 is located between the top of the core 4 in the first direction and the housing 3, the mixing space 12 is a part of the cavity 31, the inlet channel 11 is located between the side wall 41 of the core 4 around the first direction and the housing 3, the inlet channel 11 is also a part of the cavity 31, the mixing space 12 is communicated with both the inlet channel 11 and the liquid inlet channel 2, the mixing space 12 is also communicated with the outlet channel 13, the air flow output from the air source enters the mixing space 12 after entering the inlet channel 11, with a certain pressure, and impacts the aerosol atomized matrix entering the mixing space 12 from the liquid inlet channel 2, and tears the aerosol atomized matrix into small droplets, that is, atomized aerosol atomized matrix is mixed with the air flow in the mixing space 12 to form droplet particles, and the outlet channel 13 is used for ejecting the atomized droplet particles.

The viscosity of the aerosol atomization matrix adopted in the atomizer may be different, and after passing through the same atomization nozzle, the problem that the atomization particle size of the high-viscosity aerosol atomization matrix and the atomization particle size of the low-viscosity aerosol atomization matrix are large in difference easily occurs, and the atomization particle size can be understood as the diameter of the atomized liquid drop particles, so that the inconsistency of the atomization particle sizes is unfavorable for user experience.
