Described no-bead nozzle is characterized in that valve piston outer wall top is set to ramp structure, and the bottom is provided with groove, and corresponding pump housing inwall is provided with the fin on band inclined-plane.
Described no-bead nozzle is characterized in that piston rod top is provided with the through hole that is communicated with inner chamber, and needle and through hole lower port contact sealing.
Described no-bead nozzle is characterized in that the underpart of the piston rod outer wall is made as ramp structure, and the bottom is provided with the protruding circle of concave surface, by protruding circle of concave surface and pump housing sealed sliding running-fit.
Described no-bead nozzle is characterized in that needle shoulder outer wall is provided with air discharge duct.
Described no-bead nozzle is characterized in that the relevant position of pump housing upper end and loam cake is provided with air inlet duct.
Above-mentioned no-bead nozzle, simple in structure, compact, because constituent elements is few, and only uses a spring, assemble more conveniently, particularly adopted the design of no steel ball technology, avoid steel ball dirt rust, screens and influenced product quality and result of use.When product uses, comfortable feel, spraying is even, and atomizing effect is good, no water droplet phenomenon.

The specific embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the invention in detail.
As shown in the figure, this no-bead nozzle, comprise head cap 1, capping 9, connect the pump housing 6 that bottom band suction pipe 8 is set by loam cake 3 in the capping 9, stretch out capping 9 and be connected cooperation with piston rod 2 tops of the pump housing 6 sealed sliding running-fits with head cap 1, piston rod 2 inner chambers are provided with the needle 4 that the top touches cooperation, needle 4 inner chambers are provided with lower end and the pump housing 6 bonded assembly springs 5, between the pump housing 6 and needle 4 inside and outside walls valve piston 7 is set, needle 4 cooperates with valve piston 7 inside and outside slipper seals, and the pump housing 6 is sealed and matched with valve piston 7 inside and outside moving connecing.The relevant position of the pump housing 6 upper ends and loam cake 3 is provided with air inlet duct 10a, 10.Piston rod 2 tops are provided with the through hole 11 that is communicated with inner chamber, and needle 4 contacts sealing with through hole 11 lower port.Top of chamber is provided with reinforced rib in the needle 4, plays the effect of blocking spring 5.Piston rod 2 bottom outer walls are made as ramp structure, and the bottom is provided with the protruding circle 12 of concave surface, by protruding circle 12 of concave surface and the pump housing 6 sealed sliding running-fits.Piston rod 2 bottoms also can be provided with two-stage seal ring and the pump housing 6 sealed sliding running-fits.Needle 4 shoulder outer walls are provided with air discharge duct 13, and valve piston 7 outer wall tops are set to ramp structure, and the bottom is provided with groove 14, and the corresponding pump housing 6 inwalls are provided with the fin 15 on band inclined-plane.
During use, press head cap 1, piston rod 2 push down needle 4 along valve piston 7 inwalls to lower slider, the close-fitting of the inclined-plane of the inclined-plane of valve piston 7 external wall of upper portion and fin 15 sealing simultaneously, valve piston 7 is discharged from suction pipe 8 with the air in needle 4 intermediate cavity in the pump housing 6, and being compressed of the pump housing 6 inner valve needles 4 exocoels continues to press down, the air discharge duct 13 of needle 4 moves to valve piston 7 inner wall positions, and the air of exocoel is discharged by suction pipe 8 through air discharge duct 13; After loosing one's grip, under the effect of spring 5, piston rod 2 is toward last time, and valve piston 7 is along moving on the pump housing 6, the inclined-plane of valve piston 7 external wall of upper portion separates with the inclined-plane of fin 15, the cavity up and down of the pump housing 6 is communicated with, and under the effect of pressure, liquid suction passage 8, groove 14 are drawn in the pump housing 6, after several repeatedly actions, when the fluid pressure in the pump housing 6 during greater than spring 5 application forces, needle 4 separated with 2 moments of piston rod, made liquid pass through through hole 11, head cap 1 atomizing ejection.Above-mentioned valve piston 7 is realized sealing when moving down in the process of moving up and down, on when moving the inclined-plane of valve piston 7 upper inclined surface and fin 15 break away from, thereby realizing moving to connect is sealed and matched.
