The invention relates to a liquid swirl nozzle. A fixed iron is fixedly connected with a nozzle jacket; a spray head is fixed at an end of the nozzle jacket; an axial cavity is formed in the spray head; the spray head is provided with a swirl spray orifice; the axial line of the swirl spray orifice is tangential with a peripheral wall surface of the axial cavity; the spray head is provided with an axial spray orifice which is formed axially; a preloading spring cavity is formed in the fixed iron; a nozzle jacket die cavity communicated with the preloading spring cavity is formed in the nozzle jacket; the preloading spring cavity and the nozzle jacket die cavity form a water flow passage; a center pole is in slip connection in the water flow passage and is intermittently embedded into the axial cavity corresponding to the end of the center pole of the spray head; the swirl spray orifice is communicated with the nozzle jacket die cavity and the axial cavity of the spray head; the axial spray orifice is communicated with the axial cavity of the spray head; and the outer wall of the fixed iron or the fixed wall of the nozzle jacket is fixedly provided with an electromagnetic coil which drives the center pole to slide leftward and rightward. The liquid swirl nozzle has the advantages of ensuring that the liquid can be sprayed out in rotational flow from the spray orifice, having good atomization effect and the like.
Description
technical field [0001] The invention relates to a liquid nozzle, in particular to a liquid swirl nozzle. Background technique [0002] The liquid nozzle is a liquid with a certain pressure that passes through the nozzle to form fine liquid particles. The existing liquid nozzle is composed of a valve body, a valve core, a liquid inlet channel, and a spray hole, and the flow of the liquid and the pressure of the spray hole are controlled by opening and closing the valve core and the valve body. The liquid nozzle with this structure can only realize the liquid spraying out in a straight line from the nozzle orifice, and the liquid atomization effect is poor. At the same time, due to the small pressure difference, the control precision of small flow injection is low, and the system structure is complicated, the assembly process is poor, and the cost is high. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior a...
