The spray head  1  is arranged in the atomizing nozzle body  2 . A through hole  101  in the spray head  1  and a liquid through hole  201  in the atomizing nozzle body  2  form a liquid channel  701  used for delivering liquid. An airtight air channel used for delivering a spiral air flow formed by air is formed in the surface of the spray head  1 . The air channel intersects with the liquid channel  701  at an end, provided with the through hole  101 , of the spray head  1 . 
     The atomizing nozzle body  2  is used for fixing the spray head  1  and separating air and liquid from atomized air. 
     As shown in  FIG. 2 , the through hole  101  used for delivering liquid sucked by a siphon suction force is formed in the center of the spray head  1 , and a plurality of oblique grooves  102  used for forming a spiral vortex with air to generate an air flow possessing the siphon suction force are formed in the top of the spray head  1  in the circumferential direction. 
     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 . The lower end of the mist outlet  401  is communicated with an atomizing outlet of the atomizing nozzle body  2  through a channel. The atomizer shell  4  is horizontally provided with an air inlet channel  8  communicated with an air inlet  402  of the atomizing shell body  2 . 
     The atomizer shell  4  is fixed to the upper end of the atomizing nozzle body  2 . The air inlet channel  8  formed in the atomizer shell  4  is communicated with the upper end of the atomizing nozzle body  2  to guide air into the atomizing nozzle body  2 , and then the air is sprayed out via air ducts of the spray head  1 . 
     The spray head  1  is sleeved with a spray cap  5  provided with an atomizing hole  501 . The spray cap  5  is matched with the spray head  1  to form an atomizing cavity. The air ducts used for outputting air are formed by an oblique inner surface of the spray cap  5  and the oblique grooves  102  of the spray head  1 . Other configurations can also be adopted as long as the oblique grooves  102  of the spray head  1  can be sealed to form the air ducts for stable air output. 
     Wherein, the atomizing nozzle is provided with a guide channel  7 . The guide channel is fixed in the atomizing nozzle body  2  and has an end communicated with the liquid through hole  201  of the atomizing nozzle body  2  and an end communicated with the through hole  101  of the spray head  1 . 
     The guide channel  7  is a cavity having two ends provided with holes. When the hose  301  penetrates through the liquid through hole  201  of the atomizing nozzle body  2  or is communicated with the liquid through hole  201  of the atomizing nozzle body  2 , the through hole  101  in the other end of the guide channel  7  is communicated with the through hole  101  in the center of the spray head  1  to form the liquid channel  701 , and liquid in the container  3  can be guided out through the liquid channel  701  so as to be sprayed out via the through hole  101  of the spray head  1 .
