[0029] Fixed seat 20, fixed seat 20 is installed in the inside of main body 10, and the inside of fixed seat 20 is provided with nozzle core body 30;

[0030] Wherein, the one end of main body 10 is provided with water outlet 101, first air outlet 102 and second air outlet 103, and fixed seat 20 contains several guide vanes 22, guide vanes 22 annular equidistance are arranged in the outside of second air outlet 103, and the middle part of fixed seat 20 is provided with air duct 21;

[0031] The nozzle core 30 comprises a mounting seat 31, one end of the mounting seat 31 is threadedly connected with a front nozzle 32, and the inside of the mounting seat 31 is provided with an inner water pipe 33;

[0032] The middle part of the mounting seat 31 is provided with a first cavity 311, the end of the mounting seat 31 away from the front nozzle 32 is connected with an air inlet pipe 312, the inside of the front nozzle 32 is provided with a second cavity 321, the end of the front nozzle 32 away from the mounting seat 31 is provided with a through hole 322 in communication with the second cavity 321, and one end of the inner water pipe 33 is provided with a step 331.

[0033] By the cooperation of the first air jet 102 and the second air jet 103, the atomization effect and the spraying distance of the device can be improved, the high-pressure airflow of the first air jet 102 can scatter the liquid sprayed by the water jet 101, and then the second air jet 103 sprays low-pressure and large-range airflow to further scatter the water mist, thereby improving the atomization effect, and the water flow is scattered twice by the airflow, so that the atomization fineness is greatly improved; on the other hand, the spraying range and the spraying distance can be easily controlled, the high-pressure airflow of the first air jet 102 can significantly increase the water mist spraying distance, and the second air jet 103 can control the water mist diffusion range, so that the water mist spraying range and distance can be easily controlled, and the convenience and practicality of the device are improved.

[0034] As shown in Figures 1 to 7 The first air jet 102 is annular, the first air jet 102 is arranged outside the water jet 101, the second air jet 103 is arranged outside the first air jet 102, the guide vane 22 is arc-shaped, the airflow channels between adjacent two guide vanes 22 gradually decrease in the airflow direction, the step 331 abuts against the inner wall of the second cavity 321, the second cavity 321 and the first cavity 311 combine to form a high-pressure air chamber, and the inner water pipe 33 is arranged in the high-pressure air chamber.

[0035] By arranging the inner water pipe 33 in the high-pressure air chamber, the gap between the outer side wall of the pipe opening of the inner water pipe 33 and the inner side wall of the guide vane 22 is used to form the first air jet 102, so that a simple and compact structure is formed, and in terms of function effect, a very strong high-pressure airflow can be formed to achieve a very long-distance water mist spraying effect, and the atomization degree is higher;

[0036] The air flow is guided to the center axis by the guide vane 22, which has the effect that the water mist dispersed by the first air jet 102 is dispersed and atomized again, and the dispersion range of the water mist is increased, and it is worth noting here that in other embodiments, the guide vane 22 can be automatically or manually adjusted to further improve the adjustability of the water mist spray range, and the embodiment only lists one guide mode, but is not limited to it, the form of the guide vane 22 is to express that one of the concepts of the application is to control the water mist spray range.

[0037] As Figures 1 to 7 The air inlet pipe 312 is connected with the first chamber 311, and the air flow direction of the air inlet pipe 312 is inclined to extend along the air flow direction of the high-pressure air chamber. The inner water pipe 33 extends to the inside of the through hole 322 near the pipe opening of the front nozzle 32, and the first air jet 102 is formed by the gap between the inner side wall of the through hole 322 and the outer side wall of the front nozzle 32. The outer side wall of the inner water pipe 33 is provided with a plurality of through grooves 332 extending in the air flow direction, and the through grooves 332 are connected with the first air jet 102. The through grooves 332 are annularly and equidistantly distributed on the outer side wall surface of the inner water pipe 33.

[0038] The above scheme is adopted: by providing the through grooves 332, the gas in the high-pressure air chamber can enter the first air jet 102 from the through grooves 332 and be sprayed from the first air jet 102. Such a structure design is simple and ingenious, thereby facilitating processing and manufacturing.

[0039] The working principle and use process of the utility model are as follows: in actual use, the high-pressure air flow is sprayed through the first air jet 102 to achieve a primary atomization effect, then impact the liquid surface, and break the liquid column into micron-level droplets through shear force, the low-pressure and large-range air flow is sprayed through the second air jet 103 to achieve the purpose of secondary atomization, then wrap the primary atomization area, reduce the kinetic energy of the droplets, thereby prevent coalescence while expanding the spray state, then the micron-level droplets dispersed for the first time are smashed into droplets for the second time, then the water flow is dispersed through the cooperation of the two air flows, thereby improving the atomization fineness of the device, and the consistency of the droplet size is greatly improved. Moreover, the spraying distance of the water mist can be greatly increased by the high-pressure air flow of the first air jet 102, and the diffusion coverage area of the water mist can be controlled by the second air jet 103. Through the mutual cooperation of the two, the first air jet 102 cooperates with the second air jet 103 under the Venturi effect at the nozzle to form self-suction water, and the high-pressure air flow rotary cutting atomization and the low-pressure air flow secondary rotary cutting atomization are cooperated to achieve a synergistic effect, thereby making the high-pressure air flow dominant in breaking, the low-pressure air flow is optimized in distribution, and a uniform mist atomization field is formed, thereby achieving a high-efficiency and energy-saving atomization effect.
