[0019] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] like Figure 1-4 As shown, the nozzle with flow rate regulation function includes a nozzle body 1, an atomizing ball head 2, a spray slot 3 is provided on the atomizing ball head 2, and an atomizing gas port 4 and a liquid nozzle 5 are provided in the spray slot 3. The specific structure of the atomizing ball head 2 and the connection structure with the nozzle body 1 refer to the specific structure of the nozzle named a novel quantitative pulse nozzle disclosed by the applicant in the patent application number CN202221961435.9. This part of the content is not the technical solution for protection of this application.

[0021] The interior of the nozzle body 1 is provided with an atomizing gas channel 6, a control gas channel 22, a liquid channel, a regulating plug chamber 12 and a piston chamber 17. One end of the atomizing gas channel 6 forms an atomizing gas interface on the nozzle body 1, and the other end of the atomizing gas channel 6 is connected to the atomizing gas port 4.

[0022] The liquid channel includes a first section liquid channel 7, a second section liquid channel 8, a third section liquid channel 9, and a fourth section liquid channel 10. One end of the first section liquid channel 7 forms a liquid inlet 11 on the surface of the nozzle body 1, and the other end of the first section liquid channel 7 is connected to a regulating plug chamber 12. An regulating piston 13 is installed in the regulating plug chamber 12. The lower end of the regulating piston 13 is inserted into the first section liquid channel 7. The upper end of the regulating piston 13 is connected to an adjusting screw 14. A threaded hole 15 connected to the regulating plug chamber 12 is provided on the surface of the nozzle body 1. The adjusting screw 14 is threadedly connected to the threaded hole 15, and a straight groove is provided after the upper end of the adjusting screw 14 passes through the threaded hole 15.

[0023] One end of the second section liquid channel 8 is connected to the middle part of the first section liquid channel 7 through the connecting port 16, one end of the third section liquid channel 9 is connected to the second section liquid channel 8 through the connecting port 21, and the other end of the third section liquid channel 9 is connected to the piston chamber 17. A piston 18 and a spring 19 are provided in the piston chamber 17. A plunger 27 is fixedly connected to the middle part of the piston 18. The plunger 27 is inserted into the third section liquid channel 9. The piston 18 is located between the plunger 27 and the spring 19. One end of the fourth section liquid channel 10 is connected to the liquid nozzle 5, and the other end is connected to the third section liquid channel 9 through the interface 20. The interface 20 is located between the connecting port 21 and the piston chamber 17.

[0024] One end of the control gas channel 22 forms a control gas inlet 23 on the nozzle body 1, and the other end of the control gas channel 22 is connected to the piston chamber 17 through the gas port 24, and the piston 18 is located between the gas port 24 and the spring 19. After the control gas channel 22 is connected to the high-pressure control gas, the control gas enters the piston chamber 17 through the gas port 24, pushes the piston 18 to overcome the elastic force of the spring and moves, drives the plunger 27 to move, so that the fourth section of the liquid channel 10 is connected with the third section of the liquid channel 9 through the interface 20. After the liquid passes through the first section of the liquid channel 7, the second section of the liquid channel 8, the third section of the liquid channel 9, and the fourth section of the liquid channel 10 in sequence, it is sprayed out from the liquid nozzle 5 and mixed with the atomized gas sprayed from the atomizing gas port 4, so that the liquid is gasified for spraying. After the control gas is disconnected, the piston 18 is reset under the elastic force of the spring, driving the plunger 27 to move in the opposite direction, and the plunger 27 blocks the interface 20, and the connection between the third section of the liquid channel 9 and the fourth section of the liquid channel 10 is disconnected, and the liquid nozzle 5 no longer touches the liquid. Repeat the above steps to realize the pulse spraying of liquid. When the spraying flow rate needs to be adjusted, the adjusting screw 14 is rotated by a tool to move the distance of the adjusting piston 13 so that the adjusting piston 13 changes the flow rate of the liquid flowing through the communication port 21, thereby adjusting the flow rate of the entire nozzle.

[0025] Furthermore, a front seal ring 25 and a rear seal ring 26 are installed in the third section liquid channel 9, and the plunger 27 passes through the front seal ring 25 and the rear seal ring 26. The front seal ring 25 is located between the interface 20 and the piston chamber 17, and the rear seal ring 26 is located between the interface 20 and the connecting port 21. The front seal ring 25 prevents liquid from entering the piston chamber 17. The rear seal ring 26 prevents liquid from entering the fourth section liquid channel 10 when the plunger 27 is required to block the interface 20.

[0026] Furthermore, an annular groove 28 is provided on the circumferential surface of the piston 18, a piston seal ring 29 is installed in the annular groove 28, a limiting ring 30 is provided in the annular groove 28, and the limiting ring 30 is fixedly connected to the nozzle body 1. The limiting ring 30 forms a limiting effect on the movement of the piston 18. The piston seal ring 29 prevents leakage of the control gas.

[0027] Furthermore, an adjusting seal ring 31 is installed on the adjusting piston 13 , and the adjusting seal ring 31 prevents liquid from entering the adjusting plug chamber 12 .

[0028] Furthermore, the end of the regulating piston 13 away from the regulating screw 14 is tapered. The position of the regulating piston 13 is adjusted, and the amount of liquid passing through the connecting port 16 is controlled by using the tapered end.
