As shown in fig. 1, an atomizing nozzle includes an atomizing nozzle body 2, a nozzle 7 is disposed at a lower end of the atomizing nozzle body 2, a groove is inwardly disposed at an upper end portion, a medium injection port 5 is disposed at a bottom of the groove, and a water guide channel 6 is communicated between the medium injection port 5 and the nozzle 7. Atomizing nozzle main part 2 is connected with connecting piece 1 in recess one end, and 1 periphery of connecting piece is provided with the external screw thread, and recess inner wall is provided with the internal thread, and connecting piece 1 and atomizing nozzle main part 2 pass through thread sealing connection. The tip of the 1 one end of connecting piece that connecting piece 1 and atomizing nozzle main part 2 are connected is provided with connector 4, and connector 4 sets up the casing into the form of the round platform of falling, and the inside medium that is provided with of casing pours into the cavity into, and the inside of connecting piece 1 still sets up medium circulation passageway 3, and the top of connecting piece 1 is upwards stretched out to 3 one end of medium circulation passageway, and the other end stretches into the medium downwards and pours into in the cavity into.

The medium inlet 5 is also in the shape of an inverted truncated cone and is arranged in a hollow manner. The lower opening of the medium injection opening 5 is communicated with the water guide channel 6, the upper opening of the medium injection opening 5 faces the medium circulation channel 3 and is coaxially arranged with the medium circulation channel 3 and the water guide channel 6, in order to achieve the atomization effect at the position of the nozzle 7, the caliber of the lower opening of the medium injection opening 5 is smaller than the inner diameter of the medium circulation channel 3, and therefore the medium can achieve the atomization effect when being sprayed out of the nozzle 7 under the action of strong pressure through a large opening and a small opening inside the medium injection cavity.
