Nozzle. [Prior Art] As known from the prior art, a high-pressure gas flowing through a predetermined passage is used as a power source for attracting a water flow in another passage communicating therewith, and simultaneously atomizing it together In the early stage, there is a technique disclosed in the publications No. 128241 and No. 167468; the two patents have complicated structures, resulting in high cost, high failure rate and difficulty in maintenance, and The gas and liquid mixing efficiency is not good, and the particles are still too large after liquid atomization, so that the spraying distance is too short, and thus it is not widely accepted by the market. Subsequently, there is another publication No. 313,533 which discloses another nozzle which has the advantage of improving the efficiency of gas and liquid mixing, however, since it utilizes a shield at the end of the water outlet and forces the water to impel the shelter. In order to improve the structure and mode of atomization and mixing efficiency, it will lead to low energy utilization efficiency, and it is still unable to effectively improve the spray distance and so on. Therefore, there are still areas for improvement. In addition, in the foregoing patents, since they were designed at the beginning, they only focused on the spray effect, and neglected the retaining structure that must be fixed at a high place or a specific position when used, and therefore have inconvenient construction. Common shortcomings. [New content] The main purpose of this creation is to provide an atomizing nozzle with better gas-liquid mixing efficiency and effective spray distance for the lack of the above-mentioned conventional technology.
