One embodiment of the invention provides an atomizing nozzle. As shown in
The atomizing nozzle body 2 is used for fixing the spray head 1 and separating air and liquid from atomized air.
As shown in
Air is sprayed out in a staggered manner via the oblique grooves 102 in the surface of the spray head 1 to form an air flow possessing a shearing force and to apply a siphon suction force to the through hole 101 in the center of the spray head 1, so that liquid is sucked out via the liquid channel 701 and is then sheared by the air flow to form a uniform atomizing air flow.
The atomizing nozzle further comprises a container 3 used for providing liquid. The container 3 is communicated with the liquid through hole 201 of the atomizing nozzle body 2 through a hose 301.
In this application, liquid in the container 3 is delivered through the hose 301. After a siphon suction force is generated at the through hole 101, liquid in the container 3 is sprayed out via the through hole 101 in the center of the spray head 1 after passing through the hose 301 and the liquid channel 701.
In this application, the container 3 is arranged at the lower end of the atomizing nozzle body 2 and is spirally connected with an atomizer shell 4. Particularly, the liquid through hole 201 of the atomizing nozzle body 2 is in close contact and connection with one end of the hose 301, and the other end of the hose 301 is located in the container 3 to suck liquid in the container 3.
The hose 301 is arranged below the atomizing nozzle body 2 and extends into the container 3, and a liquid suction funnel 302 is reversely arranged at the tail end of the hose 301.
The atomizer shell 4 is arranged at the top of the atomizing nozzle body 2 and is provided with a mist outlet 401.
