Detailed Description

The utility model will be described in further detail with reference to the drawings and the detailed description.

The nozzle core of the atomizing nozzle comprises a cylindrical ceramic chip main body 1, as shown in fig. 2, first, a first diversion trench dam body 5a and a second diversion trench dam body 5b which are distributed in a rotary mode are arranged in a groove at the liquid inlet end of the ceramic chip main body 1, and the first diversion trench dam body 5a and the second diversion trench dam body 5b occupy a groove space at the liquid inlet end of the ceramic chip main body 1, so that main body diversion trenches 6 are formed between the first diversion trench dam body 5a and the second diversion trench dam body 5b and the ceramic chip main body 1 along the outer ring respectively. Secondly, the first diversion trench dam 5a and the second diversion trench dam 5b are in convolution distribution, a gap is formed between the first diversion trench and the second diversion trench, and the gap is used as a gap diversion trench 7 for flowing liquid from the main diversion trench 6 to the convolution center.

The first diversion trench dam body 5a and the second diversion trench dam body 5b are both convex in the grooves, the rotating centers of the first diversion trench dam body and the second diversion trench dam body are provided with openings, the openings are plunger embedded notch used for embedding the plungers, and the plungers are known structural components of the existing atomizing nozzle. The plunger inserts the plunger into the notch to block, so that the liquid flowing out of the gap diversion trench 7 directly enters the diversion inlet 8 and cannot escape from the plunger insert notch. The flow guiding inlet 1 is arranged in a groove at the liquid inlet end of the ceramic wafer main body 1 and is positioned at the center of rotation, and liquid guided by the flow guiding inlet 1 directly enters the internal cavity of the ceramic wafer main body 1.

As shown in fig. 1, a first horn mouth 2 and a second horn mouth 3 are formed on the table surface of the liquid outlet end of the ceramic wafer main body 1, and the flow guiding inlet 8 is communicated with the first horn mouth 2 through an inner cavity arranged in the ceramic wafer main body 1, so that atomized liquid is sprayed from the first horn mouth 2.

The horn mouth two 3 with the top end in a plane state is surrounded outside the horn mouth one 2, so that a space formed between the horn mouth two 3 and the horn mouth one 2 becomes a negative pressure area 4, and water mist can be well mixed with air due to the pressure difference effect, so that the beneficial effects of finer water mist particles and better diffusion effect are achieved.

As shown in fig. 3, in the inner cavity of the ceramic wafer main body 1, a main cavity 9 with an arc cavity wall and an inner horn mouth 10 with a horn shape are arranged, wherein the main cavity 9 is connected with the diversion inlet 8, the inner horn mouth 10 is connected with the runner 11, and the main cavity 9 is integrally communicated with the inner horn mouth 10. The liquid enters the main cavity in a spiral way by combining with the arrangement of the swirl type diversion trench structure at the liquid inlet end, and forms centrifugal swirl in the cavity, so that mist is sprayed out in an annular shape, and the mist shape achieves a better effect. In addition, the inner horn mouth is transited to the slender flow passage, the pressure of the mist outlet can be effectively increased by utilizing the compressibility of fluid, and the mist outlet performance of the ceramic nozzle core is greatly improved by combining annular sprayed mist.

Therefore, for the nozzle core disclosed by the utility model, liquid entering the whole atomizing nozzle is in a spiral state from the main body diversion trench 6, enters the diversion inlet 8 through the gap diversion trench 7 and further enters the main cavity 9 to form a centrifugal vortex, the slender runner 11 compresses fluid, so that mist is ejected annularly from the horn mouth I2, and the mist can be diffused more effectively under the negative pressure effect formed by the horn mouth II, so that the effect of smaller atomized particles is achieved.
