Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1-2, an atomizing nozzle includes a nozzle body 1, a nozzle head 2, and a valve core 3;

with reference to fig. 3-11, the nozzle body 1 includes a nozzle body rear section 11, a nozzle body front section 10 and a nozzle body central through hole 12, the front end surface of the nozzle head 2 has a nozzle hole 21, the rear section of the nozzle head 2 includes a nozzle head external thread 20 and a nozzle head internal thread 22, the bottom surface of the valve core 3 is a closed surface, the interior of the valve core is a hollow structure, and includes a hollow section 30, an external thread section 31 and a head section 32, and the side surface of the head section 32 is provided with at least one water outlet hole 33 communicated with the interior;

the rear section of the nozzle head 2 extends into the front section 10 of the nozzle body and is in threaded connection with the front section 10 of the nozzle body, the hollow section 30 of the valve core 3 is positioned in the front section 10 of the nozzle body, the external thread section 31 and the head 32 of the valve core 3 extend into the rear section of the nozzle head 2, the external thread section 31 is in threaded connection with the internal thread 22 of the nozzle head, liquid can enter from the central through hole 12 of the nozzle body, and flows out from the water outlet hole 33 after entering the interior from the hollow section 30 of the valve core 3 and is atomized and sprayed out from the spray hole 21.
