Example Embodiment

[0031] Example 1
[0032] The present invention is a nozzle for spraying vortex air intake type release agent, such as figure 1 As shown, it consists of nozzle cover 1, atomization head 2, gasket 3, front valve body 6, guide sleeve 7, coil frame 8, coil 9, sealing cover 10, rear housing 11, static iron core 12, moving iron core 14. Spring 15, sealing ring 16, set screw 17, etc. The atomization head 2 is arranged inside the nozzle cover 1. The nozzle cover 1 and the front valve body 6 are connected by threads, and the atomization head 2 is clamped between the nozzle cover 1 and the front valve body 6, as figure 2 Shown. The valve core of the nozzle part and the armature of the electromagnetic control part are made as a whole, namely the movable iron core 14. The front section of the moving iron core 14 is arranged inside the atomizing head 2, the middle section of the moving iron core 14 passes through the front valve body 6, and the rear section of the moving iron core 14 is arranged inside the guide sleeve 7. Such as image 3 As shown, the thickness of the thin wall of the guide sleeve 7 is 0.15 mm. The guide sleeve 7 and the front valve body 6 are connected by interference fit. A coil bobbin 8 is provided, and the coil 9 is wound on the coil bobbin 8, such as Figure 4a , Figure 4b Shown. The bobbin 8 is provided inside the rear housing 11. The static iron core 12 is arranged inside the coil bobbin 8, and the rear end of the static iron core 12 is clamped between the coil bobbin 8 and the rear housing 11 through a shaft shoulder. The rear section of the guide sleeve 7 is also arranged inside the coil bobbin 8, such as Figure 5 Shown. The movable iron core 14 is always located in the guide sleeve 7, the thin wall of the guide sleeve 7 is in contact with the coil frame 8, and the movable iron core 14 does not contact the coil frame 8. The bottom surface of the rear housing 11 is provided with an electromagnetic coil wiring outlet 23, and the rear end of the rear housing 11 has two through holes 24, such as Image 6 As shown, the front valve body 6 has two first threaded holes at the corresponding connection positions, the front valve body 6 and the rear housing 11 are connected by a stud, and the stud passes through the through hole 24 to connect with the first threaded hole.
[0033] There is a gap between the moving iron core 14 and the static iron core 12, which is the air gap 13; when the nozzle is closed, such as figure 1 As shown, if energized, the moving iron core 14 will move backward and move within the range of the air gap 13.
[0034] A spring 15 is sleeved on the rear section of the movable iron core 14 inside the guide sleeve 7, a gasket 3 is provided between the end of the nozzle cover 1 and the front valve body 6, and the end of the rear housing 11 is provided with a sealing cover 10, and the movable iron A sealing ring 16 is provided between the middle section of the core 14 and the front valve body 6, and an atomization outlet 21 is provided at the front of the nozzle cover 1.
[0035] Such as Figure 7a-Figure 7d As shown, the front end of the atomization head 2 is provided with a small hole 20, the inside of the atomization head 2 is provided with a boss 25, the small hole 20 is provided in the middle of the boss 25, and the outside of the atomization head 2 is provided with 3-6 A uniformly distributed spiral channel 28. In this embodiment, the outer side of the atomization head 2 is provided with 4 evenly distributed spiral channels 28.
[0036] When the electromagnetic nozzle is in a power-off state, the movable iron core 14 is in contact with the boss 25, which can more reliably close the release agent channel (that is, the small hole 20 at the front end of the atomizing head 2). The atomizing gas channel of the atomizing head 2 is designed as four spiral channels 28 distributed symmetrically. The spiral channel 28 can guide the originally linearly moving atomizing gas into a rapidly rotating and turbulent airflow, which can produce a better atomization effect after being mixed with the release agent.
[0037] Such as Figure 8a-Figure 8c As shown, the front end surface of the front valve body 6 is provided with four second threaded holes 22 for positioning and installing the electromagnetic nozzle. A release agent channel 19 is opened on the side of the front valve body 6. Due to the needs of parts processing, the release agent channel 19 is designed as a through hole, and a set screw 17 is installed in the release agent channel 19. The bottom surface of the front valve body 6 is provided with a release agent radial channel 18 and an atomizing gas radial channel 5. The front valve body 6 is provided with a release agent axial channel 26 in the middle. The release agent axial channel 26 communicates with the release agent radial channel 18. The front valve body 6 has grooves at the front and back ends. 6 An atomizing gas axial channel 4 is provided in the slot at the front end of the slot, and the atomizing gas axial channel 4 and the atomizing gas radial channel 5 are connected. The middle of the front valve body 6 is provided with a groove 27 into which the sealing ring 16 can prevent the release agent liquid from entering the rear section of the electromagnetic nozzle. The groove 27 is provided in the passage between the groove at the rear end of the front valve body 6 and the release agent axial passage 26.
[0038] The invention can increase the mixing space at the atomization outlet 21, so that the atomization gas and the release agent solution are more fully mixed before spraying, so as to achieve the effect of preliminary atomization. The electromagnetic force can be increased, and the winding shape of the coil bobbin 8 can be changed from rectangular to circular.
