Intelligent sway water sprayer

Abstract

The invention relates to an intelligent sway water sprayer, which is a collocation comprising a soil humidity measure and control instrument, a joint, an energy-saving spray irrigation timer and a water sprayer, wherein the joint has sizes and screw pitches of finely adjustable thread rings, and the energy-saving spray irrigation timer is provided with a multipurpose connector. The intelligent sway water sprayer relates to a method for directly observing and controlling soil humidity at low cost. Air humidity and the soil humidity are not completely consistent sometimes. By adopting the method that two simple polar plates are directly into soil without using hygristors to observe and control the soil humidity and when the soil is dry, the intelligent sway water sprayer is started when resistance between the polar plates inserted into the soil is too high to threshold voltage to intelligently irrigate the soil at regular time, so that low-cost reliable intelligent timer products are possible. By utilizing the principle that not only do the steel wire pitches become small but also diameters of springs becomes large when the springs are pressed, not only are the finely adjustable thread rings (41) reduced in intervals among all ring layers, i.e., the screw pitches are reduced along with the decrease of the steel wire pitches by side faces of a plurality of clamp springs (48) but also the finely adjustable thread rings (41) are squeezed in the radial direction along with the increase of the diameters of the springs to get close to the center, and the threaded joint can be rapidly and simultaneously clamped in the axial direction and the radial direction. The intelligent sway water sprayer is skillful in conception.

Description

technical field [0001] The invention relates to a control method of water flow for environmental protection and landscaping, which is an intelligent swing sprinkler, a mechanical timer and a mechanical timer with a newly added auxiliary spring with a joint that can fine-tune the size and pitch of the thread ring. The improvement on the basis of the energy-saving sprinkler irrigation timer with multi-purpose interface, the important content is to apply a simple method of measuring soil moisture to the improvement of intelligent swing sprinkler. Background technique [0002] The desire to pursue environmental protection and landscaping is endless; there are also many patents on the control method of watering water flow, and the timing switch of garden sprinklers controlled by both sides of the long axis, such as patent US7252113B2, and Patent ZL200820120164.8 all adopts the timing switch of the garden sprinkler controlled by both sides of the long axis. Although the mechanica...
