Description of drawings
Below in conjunction with accompanying drawing and specific embodiment the present invention is described further:
Fig. 1 is the profile of the embodiment of the invention;
Fig. 2 is the front view of the embodiment of the invention;
Fig. 3 is the front view of embodiment of the invention powder pump;
Fig. 4 is the profile of embodiment of the invention powder pump.
The specific embodiment
With reference to Fig. 1, Fig. 2; A kind of multifunctional shower nozzle of the present invention; Comprise electrostatic spraying storehouse 1 and be installed in the powder pump 2 on the electrostatic spraying storehouse 1 that be provided with cavity 11 in the said electrostatic spraying storehouse 1, said powder pump 2 is provided with the through hole 21 that is communicated with cavity 11; It is characterized in that: be set with ceramic innermost tube 3 in the said through hole 21, said electrostatic spraying storehouse 1 be provided be communicated with cavity 11 respectively advance the coating passage 12 and the first high pressure admission passage 131.
As preferred implementation of the present invention; Pottery innermost tube 3 stretches in the through hole 21 from powder pump 2 one sides; And with through hole 21 inwall interference fit, and the end of ceramic innermost tube 3 is provided with boss 31, said boss 31 withstands on the outer face of through hole 21 towards a side of powder pump 2; The end face that this boss 31 withstands on powder pump 2 can prevent that boss 31 from passing through hole 21 and going out powder pump 2 under the hyperbar effect.
Further, a side of powder pump 2 suits pottery innermost tube 3 extend in the cavity 11.
As preferred implementation of the present invention, it is protruding 12 that the inboard of said electrostatic spraying storehouse 1 cavity 11 is provided with, and said boss 31 is towards side of cavity 11 and protruding 12 apical graftings mutually; This convexity 12 can further be blocked ceramic innermost tube 3, guarantees that shower nozzle remains good serviceability.
As preferred implementation of the present invention, powder pump 2 outer walls are provided with external screw thread 22, and said cavity 11 inwalls are provided with external screw thread 22 and cooperate to fixedly mount the internal thread 27 of powder pump 2; Powder pump 2 is convenient to dismounting with electrostatic spraying storehouse 1 through being threaded, and connection is tightr, can prevent that paint from infiltrating under the hyperbar effect.
As preferred implementation of the present invention, said powder pump 2 is provided with baffle plate 23 near external screw thread 22 outboard end, is provided with sealing ring 24 between said baffle plate 23 and the external screw thread 22, and baffle plate 23 opposite sides are provided with polyhedron columnar projections 25; Sealing ring 24 combines with baffle plate 23 can further play sealing function, improves spray efficiency, strengthens spraying effect, and the dismounting that clamps that polyhedron columnar projections 25 helps instrument such as spanner is set in addition.
