Multi-stage swing horticultural watering appliance

A multi-stage swing horticultural watering appliance comprising:

• a base, a water-dispensing basin, a swing device, a spraying cover and a swing outlet pipe, the base being formed in a center thereof with a circular receiving recess, the water-dispensing basin being received in the circular receiving recess and being rotatable step by step, the swing device installed in the water-dispensing basin and including a turbine wheel, a drive member, a follower, a sleeve, a driven shaft, a swing arm, a link ring and a positioning member, the turbine wheel being rotatably mounted on two supporting rods inside the water-dispensing basin, the drive member being pivotally mounted on a hollow pillar inside the water-dispensing basin and meshed with the turbine wheel and the follower by teeth, the follower mounted on an end of the driven shaft, the sleeve being mounted on a mid portion of the driven shaft and then being placed on the positioning member mounted on supporting columns inside the water-dispensing basin, another end of the driven shaft being pivoted to an end of the swing arm, and another end of the swing arm pivoted to a link rod of the link ring, the spraying cover fixed on the water-dispensing basin by high frequency welding;
• wherein an inlet hole and an outlet connector are arranged at two opposite sides of the receiving recess of the base, a plurality of inlet apertures is formed in an outer periphery of the water-dispensing basin, and in the water-dispensing basin are provided with a water-supplying pipe and a plurality of water-separating boards, in use, water flows through the inlet hole of the base and into the water-dispensing basin via the inlet apertures, a rectangular groove is formed in the spraying cover for accommodation of the swing outlet pipe, a through hole is formed in one end of the rectangular groove, the swing outlet pipe is formed with a plurality of spraying apertures, one end of the swing outlet pipe passes through the through hole of the rectangular groove and is connected to the link ring of the swing device, and in this one end of the swing outlet pipe is formed an inlet hole, water flow pushes the swing device to swing, thus driving the swing outlet pipe to swing back and forth, when the water-dispensing basin is full of water and the pressure therein reaches a certain level, the water will flow into the swing outlet pipe via the inlet hole thereof and will be sprayed out via the spraying apertures.
