As shown in fig. 1, the swirl atomization anti-blocking sprayer provided by the invention comprises a shell 11, a shell cap 7 and a nozzle 1, wherein the shell 11, the shell cap 7 and the nozzle 1 are provided with inner cavities, the inner cavities are coaxially provided with spiral connecting rods 9, the inner cavities and the spiral connecting rods 9 are both arranged into circular structures, and the circular structures can enable the rotation effect of the spiral connecting rods 9 to be better, so that the spiral connecting rods 19 have larger centrifugal force during rotation and have better atomization effect. It should be noted that the nozzle 1, the housing 11 and the housing cap 7 are sequentially and hermetically connected through a thread, the spiral link 9 is fixed on an inner cavity through the bearing 5 and can rotate, and the inner cavity of the housing and the spiral link 9 form a first atomization chamber 14.
The shell 11 is provided with a liquid inlet channel 13 and an air inlet channel 3, one end of the liquid inlet channel 13 is connected with a liquid inlet pipe 12, and the other end is communicated with the inner cavity of the shell 11; one end of the air inlet channel 3 is connected with an air inlet pipe 4, and the other end is communicated with the inner cavity of the shell. The liquid inlet channel 13 and the gas inlet channel 3 are coaxially arranged, so that the nutrient solution and the compressed gas can directly impact when entering the first atomizing chamber 14, and the atomizer has a better impact effect, so that the atomization effect of the atomizer is better and more uniform. It should be noted that the inlet channel 13 is an inlet of the plant nutrient solution flowing into the first atomization chamber 14, and the inlet channel is an inlet of the compressed gas flowing into the first atomization chamber 14.

The prepared nutrient solution is poured into a storage tank, is pressurized by a water pump, flows into the liquid inlet channel 14 through the liquid inlet pipe 12, and is sprayed into the first atomizing chamber 14 at high speed; after the gas is pressurized by the gas pump, the compressed gas flows into the gas inlet channel through the gas inlet pipe 4 and then is sprayed into the first atomizing chamber 14 at high speed; the gas inlet channel 3 and the liquid inlet channel 13 are arranged coaxially, the nutrient solution sprayed at high speed and the high-speed compressed gas are violently collided, the impact force is far greater than the surface tension of the nutrient solution, so that the nutrient solution is separated to form liquid drops, and the liquid drops formed after collision are scattered to the periphery and continuously collide with the inner cavity wall to form small liquid drops.

It should be noted that, after the nutrient solution and the compressed gas collide with each other for a plurality of times, the nutrient solution is changed from the liquid to filamentous liquid droplets with extremely unstable flow state in the first atomizing chamber 14, so as to form better atomizing effect in the second atomizing chamber 15.

The liquid inlet channel 13 and the gas inlet channel 3 are coaxially arranged, so that nutrient solution and compressed gas can directly impact when entering the first atomizing chamber 14, and the high-impact spray nozzle has a better impact effect, so that the spiral connecting rod 9 can rotate quickly, generate a larger centrifugal force, and effectively impact the sediment in the spray nozzle. It should be noted that the inlet channel 13 is an inlet of the plant nutrient solution flowing into the first atomization chamber 14, and the inlet channel is an inlet of the compressed gas flowing into the first atomization chamber 14.
As shown in fig. 5, the spiral link 9 is provided with the spiral blade 2, the spiral blade 2 extends from the first atomization chamber 14 to the second atomization chamber 15, and the spiral blade 2 of the present invention can have an impact cleaning effect under the centrifugal force generated by the rotation motion, so as to effectively remove the deposits in the inner cavity of the housing and the inner cavity of the nozzle.
In the spray cultivation, the nutrient solution is treated by an atomizer to form a mist shape and is uniformly sprayed to the roots of plants, various mineral elements exist in the nutrient solution, and substances which are easy to precipitate such as the mineral elements and the like can be precipitated on the atomizer when the nutrient solution is atomized by the atomizer, so that the atomizer is blocked. The sprayer is provided with the air inlet channel 3 and the liquid inlet channel 13 which are coaxial, nutrient solution sprayed at high speed is violently collided with high-speed compressed gas, the impact force is greater than the surface tension of the nutrient solution, so that the nutrient solution is separated to form liquid drops, the liquid drops formed after collision are scattered to the periphery and continuously collide with the inner cavity wall, and the small liquid drops moving at high speed are not easy to precipitate. In addition, the air inlet channel 3 and the liquid inlet channel 13 are respectively arranged at two sides of the shell 11, the axes of the air inlet channel 3 and the liquid inlet channel 16 are perpendicular to the axis of the spiral connecting rod, the nutrient solution and the compressed gas sprayed at high speed are directly sprayed onto the spiral connecting rod 9 to push the spiral connecting rod 19, so that the spiral connecting rod 9 rotates anticlockwise at high speed, the spiral connecting rod 9 rotating at high speed generates larger centrifugal force, the centrifugal force is far greater than the adsorption force of precipitates, and the precipitates adsorbed in the inner cavity of the shell and the inner cavity of the nozzle are sprayed out of the sprayer along with fog drops, thereby eliminating the condition that the sprayer is blocked by the precipitates.
The above examples only show several embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the invention. It should be noted that various changes and modifications can be made by those skilled in the art without departing from the spirit of the invention, and these changes and modifications are all within the scope of the invention. Therefore, the protection scope of the present patent should be subject to the appended claims.
