Description

Technical Field

[0001] The utility model relates to the technical field of nozzles, in particular to a nozzle core. Background Art

[0002] The nozzle core is the core component of the atomizing nozzle, which is mostly made of ceramic sheets. The atomized liquid outlet end of the traditional atomizing nozzle ceramic sheet is a planar structure, with only one atomized liquid water spray outlet, and the atomized liquid is directly sprayed out from the water spray outlet; the nozzle and the nozzle seat in the existing technology are integrally formed, and the angle of the water spray outlet cannot be adjusted. For example, as shown in the nozzle core of an atomizing nozzle with Chinese patent application number CN202320823339.6, the liquid delivered by the slender flow channel is sprayed out through the first bell mouth. By utilizing the compressibility of the fluid, the pressure of the mist outlet can be effectively increased. At the same time, a negative pressure area is formed around the second bell mouth. Due to the pressure difference, the sprayed water mist can be more fully mixed with the air.

[0003] However, since the ceramic sheet body and the nozzle are integrally formed, and the actual spray angle of the nozzle cannot be adjusted by adjusting the opening angle of the bell mouth, it is not convenient for the nozzle core to quickly adjust the opening angle according to different usage scenarios.
