Full flow opening structure of gardening-used figure sprinkling head
DC
First Claim
1. A full flow opening structure of gardening-used figure sprinkling head, comprising a sprinkling gun having a head section connected with a figure sprinkling head, the sprinkling head being composed of a figure water discharging cover and a bottom cap watertightly fused with each other by ultrasonic wave, a conic post formed with thread hole being disposed at a center of interior of the sprinkling gun, the conic post being passed through a central through hole of the figure sprinkling head and connected therewith by a screw, a water exit and a locating hole being formed in a head section of the sprinkling gun, a spring pin being inserted in the locating hole, a stepped opening being formed in the water exit and spaced from an end face thereof by a certain distance, a water sealing O-ring being disposed in the stepped opening, an inner periphery of the water discharging cover being formed with multiple radially arranged ribs for connecting with a circular screen plate, a full flow opening being defined between the ribs, an inner portion of the screen plate being disposed with several different annularly arranged figure sprinkling holes and two blind faces, each figure sprinkling hole having a rearward extending hollow post, the bottom cap being disposed with several annularly arranged water entrances and a hollow water incoming post having a circular hole on end face, a back face of the bottom cap being formed with seven locating recesses annularly arranged along the outer periphery thereof corresponding to the water entrances and hollow water incoming post, said full flow opening structure being characterized in that the exit of each full flow opening is disposed with an inclined flange, the periphery of the screen plate being disposed with a rearward extending annular partitioning board having equally interlaced poles, the partitioning board and the inner wall of the water discharging cover defining therebetween a full flow water passage, one of the blind faces having a rearward extending full flow opening guide flange shaped as a balloon flask and connecting with the partitioning board of the screen plate and communicated with the full flow water passage, the full flow opening at the exit of the guide flange being closed, whereby the figure sprinkling head is rotatable to align the water entrance of the bottom cap corresponding to the guide flange of the water discharging cover with the water exit of the head section of the sprinkling gun, so that the water will flow from the water exit of the sprinkling gun through the water entrance of the bottom cap to the head section of the guide flange to evenly collect, then the water being guided by the guide flange to impact the inner wall of the water discharging cover and laterally flow and evenly enter the full flow water passage, then the water being guided by the inclined flange at the exit of the full flow opening to evenly scatter flow to the respective full flow openings and smoothly discharge in an even weak state.

Abstract
A full flow opening structure of gardening-used figure sprinkling head, including a sprinkling gun connected with a figure sprinkling head, the sprinkling head being composed of a figure water discharging cover and a bottom cap watertightly fused with each other by ultrasonic wave. A conic post formed with thread hole being disposed at a center of interior of the sprinkling gun. An inner periphery of the water discharging cover is formed with multiple radially arranged ribs for connecting with a circular screen plate. A full flow opening is defined between the ribs. The exit of each full flow opening is disposed with an inclined flange. The periphery of the screen plate is disposed with a rearward extending annular partitioning board. The partitioning board and the inner wall of the water discharging cover define therebetween a full flow water passage. An inner portion of the screen plate is disposed with several different annularly arranged figure sprinkling holes and two blind faces. Each figure sprinkling hole has a rearward extending hollow post. One of the blind faces has a rearward extending full flow opening guide flange shaped as a balloon flask and connecting with the partitioning board of the screen plate and communicated with the full flow water passage. The full flow opening at the exit of the guide flange is closed.
