Furthermore, the shower nozzle includes nested interior stem and outer tube together, the top of interior stem set firmly with the chuck of shower nozzle cover looks adaptation, seted up spiral ammonia water groove on the outer wall of interior stem, seted up in the chuck by its top center downwardly extending and with the inlet channel that the upper shed of ammonia water groove is linked together, the bottom center of interior stem seted up with the shower nozzle hole that the end opening of ammonia water groove is linked together.

Furthermore, the nozzle fixing seat is connected to one end of the short vertical rod through threads.

Furthermore, the nozzle sleeve comprises a cylindrical outer ring piece fixedly arranged at the bottom of the nozzle fixing seat and a circular inner edge piece fixedly arranged at the bottom of the outer ring piece.

Adopt the produced beneficial effect of above-mentioned technical scheme to lie in:

the utility model discloses under the condition that does not increase external force influence, the simple change shower nozzle inner structure, utilize the rotatory inertia of shower nozzle and rely on mobile medium and the pressure effect in the shower nozzle to make the shower nozzle rotatory, can prevent effectively that the aqueous ammonia from causing the jam of shower nozzle to the rust that compressed air pipeline corrodes the production and the water in the compressed air, debris such as oil to can evenly spout atomizing aqueous ammonia, make NOx fall to certain effect value.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1-5, the utility model discloses a spray gun with rotary spray head, which comprises a spray rod 3 and a fixed flange 2 fixedly arranged on the spray rod 3, and a pipeline interface 1 is arranged at one end of the spray rod 3; the spray rod 3 comprises a long cross rod and a short vertical rod which is vertical to the long cross rod and fixedly connected with the long cross rod, the fixed flange 2 is fixedly arranged on the long cross rod, and the pipeline interface 1 is fixedly arranged at one end of the long cross rod; a spray head fixing seat 4 is fixedly arranged at one end of the short vertical rod, the long transverse rod, the short vertical rod and the spray head fixing seat 4 are all of hollow structures, and hollow cavities of the long transverse rod, the short vertical rod and the spray head fixing seat are communicated; the shower nozzle fixing base 4 passes through threaded connection in the one end of short montant, and the bottom of shower nozzle fixing base 4 is provided with annular shower nozzle cover of circle, and movable mounting has rotatable shower nozzle 5 in the shower nozzle cover. The nozzle cap comprises a cylindrical outer ring piece fixedly arranged at the bottom of the nozzle fixing seat 4 and a circular inner edge piece fixedly arranged at the bottom of the outer ring piece. The spray head 5 comprises an inner core column and an outer sleeve which are nested together, the top of the inner core column is fixedly provided with a chuck matched with the spray head sleeve, and the chuck is movably arranged in the spray head sleeve; the outer wall of the inner core column is provided with a spiral ammonia water tank, the chuck is internally provided with a water inlet channel which extends downwards from the center of the top of the chuck and is communicated with the upper opening of the ammonia water tank, and the center of the bottom of the inner core column is provided with a nozzle hole communicated with the lower opening of the ammonia water tank.
