[0027] Embodiment 1:

[0028] Figure 1-Figure 7 The utility model shows a novel atomizing nozzle, comprising a nozzle core 2 and a nut 1. The side end surface of the middle part of the nozzle core 2 is provided with an external thread, and the nut 1 is provided with an atomizing groove 11. The atomizing groove 11 is provided with an internal thread that can cooperate with the external thread, so that the nozzle core 2 is threadedly screwed into the atomizing groove 11. At this time, the nozzle core 2 is partially embedded in the nut 1, and the diameter of the embedded part is smaller than the atomizing groove 11, so that a water storage chamber 3 is formed between the nozzle core 2 and the atomizing groove 11 for water to pass through;

[0029] The end of the nozzle core 2 away from the nut 1 is a water inlet end face 21, and a water inlet hole 22 is provided on the water inlet end face 21. The end of the nozzle core 2 embedded in the nut 1 is an atomizing end face 24. A water outlet hole 23 is provided at the side end face of the nozzle core 2 near the atomizing end face 24. The water outlet hole 23 is connected with the water inlet hole 22 to form a cavity inside the nozzle core 2 for water to pass through, so that water can flow from the outside into the water storage chamber 3 through the water inlet hole 22 and the water outlet hole 23;

[0030] A swirl groove 25 is provided on the atomizing end face 24. When the nozzle core 2 is embedded in the nut 1, the atomizing end face 24 abuts against the bottom of the atomizing groove 11. At this time, a swirl channel 4 is formed between the swirl groove 25 and the atomizing groove 11. An atomizing nozzle 12 is provided at the bottom of the atomizing groove 11. The swirl channel 4 can allow water to flow from the water storage chamber 3 to the atomizing nozzle 12.

[0031] The axes of the water inlet hole 22 and the water outlet hole 23 are perpendicular to each other, and the two water outlet holes 23 are symmetrically arranged along the axis of the water inlet hole 22. When the nozzle core 2 is processed and manufactured, the two water outlet holes 23 can be drilled and formed on the raw material of the nozzle core 2 through one processing, and the water inlet hole 22 can also be processed and formed at one time, so that the manufacturing process of the nozzle core 2 is simple and the manufacturing cost is low.

[0032] The spiral groove 25 includes four straight grooves, which are arranged along the tangent direction of the atomizing nozzle 12 and are evenly arranged along the circumference of the atomizing nozzle 12. The axes of two adjacent straight grooves are perpendicular to each other. The input end of the straight groove is arranged on the outer edge of the atomizing end face 24, and the output end is connected to the atomizing nozzle 12.

[0033] The atomizing nozzle 12 includes a swirl portion 13, which is funnel-shaped and has a large diameter end, i.e., an input end, which is connected to the swirl groove 25. The atomizing nozzle 12 includes a direct current portion 14, and the input end of the direct current portion 14 is connected to the output end of the swirl portion 13. The output end of the direct current portion 14 has a chamfer. After passing through the swirl channel 4 and the swirl portion 13, the water flow is sprayed out from the direct current portion 14 in the form of atomized small water droplets.

[0034] Working principle:

[0035] First, tighten the nozzle core 2 into the nut 1, and then connect the water source to the water inlet hole 22. Water flows into the water storage chamber 3 from the water inlet hole 22. The water in the water storage chamber 3 flows into the atomizing nozzle 12 from the swirl channel 4 formed by the swirl groove 25 and the atomizing groove 11. The rotating motion causes the water to be divided into small droplets, which are then sprayed out from the atomizing nozzle 12.

[0036] The spraying angle of the atomizing nozzle 12 is related to the diameter and length of the atomizing nozzle 12. When the water outlet hole 23 is 0.6 mm and the wall thickness of the nut 1 is 0.3 mm, the spraying angle is 60°. When the water outlet hole 23 is 0.6 mm and the wall thickness of the nut 1 is 0.2 mm, the spraying angle is 70°.

[0037] The above description is only an optional embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
