Detailed Description

The present invention will be described in further detail with reference to the following drawings and specific embodiments. In the present specification, the terms "upper", "inner", "middle", "left", "right" and "one" are used for convenience of description, and are not intended to limit the scope of the present invention, and the relative relationship between the terms and the corresponding parts may be changed or adjusted without substantial technical changes.

As shown in fig. 1 and 4, an atomizing nozzle comprises a nozzle body, the nozzle body comprises an inlet pipeline 1, an atomizing cavity 2 and an atomizing hole 3, the inlet pipeline 1 is connected with the atomizing cavity 2 and communicated with the atomizing cavity 2, the atomizing cavity 2 is connected with the atomizing hole 3 and communicated with the atomizing hole, an atomizing mechanism 4 is arranged in the atomizing cavity 2, a drainage piece 5 which enables a liquid channel 13 in the inlet pipeline 1 to be gradually narrowed towards the atomizing cavity 2 is arranged in the inlet pipeline 1, and liquid in the inlet pipeline 1 is guided to the atomizing mechanism 4 in the atomizing cavity 2 through the drainage piece 5 to be atomized. Make the drainage piece 5 that liquid passage 13 in the inlet pipeline 1 diminishes gradually through the setting, make liquid follow inlet pipeline 1 enter the back because liquid passage 13 diminishes, the velocity of flow of liquid crescent, be favorable to follow-up with liquid dispersion and atomizing, inlet pipeline 1's liquid passes through the atomizing mechanism 4 department in drainage piece 5 guide to the atomizing chamber 2 simultaneously, make the liquid after the velocity of flow grow atomize at once, thereby just need not use the condition of atomizing air supply at equal water pressure, can reach the best atomization effect. Meanwhile, the atomization of the liquid can be well realized without the limitation of an air source and excessive water pressure, and the purposes of reducing cost and facilitating popularization and use are achieved.

As shown in fig. 1-2, the flow-guiding member 5 is an inverted cone, the apex of the cone faces the inlet conduit 1, the bottom surface of the cone is connected to the bottom of the atomizing mechanism 4, so that the liquid gradually disperses to the edges of the cone as it passes through the cone, and the smooth and gradual side surfaces of the cone help to reduce the resistance and increase the flow rate.

As shown in fig. 1-3, the atomizing mechanism 4 includes a spiral blade 41 and a valve core 42 rotatably installed in the atomizing chamber 2, the spiral blade 41 is uniformly installed on the side surface of the valve core 42, a rotating water tank 43 is arranged between the spiral blade 41 and the spiral blade 41, and the bottom of the valve core 42 is connected with the bottom surface of the cone. Through the water tank formed by the valve core 42 and the helical blade 41, the liquid with improved flow velocity passes through the rotating water tank 43 and impacts the rotating tank to generate a certain circumferential force, so that the valve core 42 and the helical blade 41 rotate along with the rotating water tank to form a rotating liquid flow, and the rotating liquid flow collides with the inner wall of the atomizing cavity 2 and is dispersed and smashed. The outer surface of the spiral blade 41 encloses a circle and forms an axial concentric circle with the valve core 42, and the diameter of the circle enclosed by the valve core 42 and the spiral blade 41 is gradually reduced from the bottom to the top. So that the liquid can form circumferential force more easily through the rotating water tank 43, the rotating resistance of the valve core 42 and the helical blade 41 is reduced, the rotating speed is improved, and the dispersion and the smashing of the liquid flow are better realized. The bottom of the valve core 42 and the bottom surface of the cone are concentric circles, the diameter of the bottom surface of the cone is smaller than or equal to that of the bottom of the valve core 42, the cone is prevented from blocking the rotary water tank 43, when the diameter of the bottom surface of the cone is equal to that of the bottom of the valve core 42, the flow rate of liquid can be improved to the maximum extent, the resistance of the liquid smoothly passing through the rotary water tank 43 is minimum, and the optimal conditions are made for the subsequent atomization effect. The valve core 42 is rotatably connected with the cone, so that the rotation of the valve core 42 is not influenced, and the rotation resistance of the valve core 42 is reduced.

As shown in fig. 1-3, the atomizing chamber 2 is circular and the bottom and top of the atomizing chamber 2 have a smaller diameter than the middle, so that the rotating water stream can better collide and bounce against the atomizing chamber 2. The top in atomizing chamber 2 is equipped with water smoke chamber 6, and the inner wall diameter in water smoke chamber 6 diminishes from the bottom to the top, and the top in water smoke chamber 6 communicates with each other with the bottom rigid coupling in spraying hole 3, and spraying hole 3 is the big infundibulate of bottom in top. Therefore, the crushed liquid drops are further crushed through the collision of the water mist cavity 6, are mixed and atomized through the gas flowing in the atomizing holes 3 and then are sprayed out of the atomizing holes 3, and therefore the atomization of the liquid is efficiently realized, and the atomized liquid drops are finer and smoother.

As shown in fig. 1-4, inlet pipe 1 includes inlet tube 11 and drainage tube 12, drainage tube 12 is the cylinder type, the top of drainage tube 12 is connected and the top rigid coupling of bottom and inlet tube 11 with atomizing chamber 2, the bottom of inlet tube 11 can be dismantled with sleeve pipe 9 and be connected, the bottom of inlet tube 11 is equipped with filter screen 7, thereby filter liquid, avoid atomizing mechanism 4 to block up, and can dismantle the convenient filter residue that clears up in the filter screen 7 of design, inlet tube 11 is equipped with sealing washer 8 with sleeve pipe 9's junction, avoid the weeping, the diameter of inlet tube 11 inner wall diminishes from filter screen 7 to drainage tube 12 gradually, can tentatively promote the velocity of flow of liquid, make things convenient for follow-up reposition of redundant personnel and atomizing.

When the device is used, the sleeve 9 is communicated with a water source, water flows through the filter screen 7 in the liquid inlet pipe 11 to filter impurities, flows into the area where the diameter of the inner wall of the liquid inlet pipe 11 is gradually reduced, so that the flow rate of the water flow is increased, and flows into the drainage pipe 12; then the water flow is guided by the drainage piece 5 and the liquid channel 13 is gradually reduced, so that the flow rate of the water flow is further improved, the water flow is guided into the rotating water tank 43 between the spiral blades 41 through the side surface of the cone, the water flow enters the rotating water tank 43 and impacts the inner wall of the rotating water tank 43 to generate circumferential force, the valve core 42 rotates to form rotating water flow, the spiral blades 41 are gradually reduced to enable the water tank to be gradually reduced, so that the flow rate is improved again in the rotating process of the water flow, the high-speed rotating water flow impacts the atomizing cavity 2, the water flow is further impacted, dispersed and smashed into small liquid drops, the small liquid drops impact the inner wall of the water mist cavity 6 again through the water mist cavity 6 with the gradually reduced inner wall diameter, the small liquid drops are further dispersed and smashed and the flow rate of the small liquid drops is improved, when the connecting position between the water mist, the static pressure reaches the minimum value, and the external atmospheric pressure is greater than the static pressure at the position, so that air enters through the funnel-shaped spraying holes 3 and is fully mixed with liquid flow at the position to achieve the strongest atomization effect, and finally, the air is quickly sprayed out through the spraying holes 3 and is jetted into the air. Therefore, under the conditions that an atomization air source is not needed and high-pressure water flow is not needed, good atomization effect can be achieved only by using medium-low pressure water flow, atomization cost is saved, and the application range is wider.
