CA3187775A1 — Nebulizing device

USPTO Abstract

A nebulizing device (100), comprising: a hollow housing (101) having a cavity (110), the cavity (110) having a liquid channel (111) located therein and a nebulizing nozzle (103) located at a distal end of the liquid channel (111) and having a plurality of fluid outlets; an injector (102), which is at least partially accommodated in the cavity (110) and comprises a liquid storage device (120) for accommodating liquid; a liquid conveying pipe (121) having a liquid suction end (122) and a liquid outlet end (123), the liquid suction end (122) being located in the liquid storage device (120), the liquid outlet end (123) being located in the liquid channel (111), and the liquid outlet end (123) and the nebulizing nozzle (103) jointly define a liquid cavity (124); the injector (102) near end, which is coupled to the liquid conveying pipe (121) and used for receiving pushing force, so that the liquid conveying pipe (121) can move in the cavity from the near-end position to the far-end position to form preset nebulizing pressure at the nebulizing nozzle (103), and the liquid is enabled to flow out through the nebulizing nozzle (103) and be collided in an intersecting mode, to generate spray having a predetermined initial plume speed; at least 50% of the droplets in the spray have an average particle size ranging 1 µm to 10 µm.
