Novel large-flow garden irrigation timer

Abstract

The invention relates to a novel large-flow garden irrigation timer. The novel large-flow garden irrigation timer comprises a water-taking pump pipeline, a double-selection water-pumping pool tap water valve, a spraying water-throwing device, an intelligent swinging water sprayer, a soil humidity measuring and controlling device, a joint with the thread ring size and thread pitch capable of being finely adjusted, an energy-saving spray irrigation timer with a multipurpose connector and a water sprayer, wherein the joint is used in cooperation with the energy-saving spray irrigation timer and the water sprayer. The method for measuring and controlling the soil humidity is direct and low in cost. Based on the principle that the steel wire pitch is decreased and the spring diameter is increased when a spring is compressed, the side faces of a plurality of clamping springs (48) enable the layer-to-layer interval of a plurality of thread rings (41) capable of being finely adjusted to be decreased along with decrease of the steel wire pitch, namely, the thread pitch is decreased, besides, the thread rings (41) are squeezed in the radial direction along with increase of the spring diameter so as to get close to the center, and therefore the threaded joint can be rapidly clamped in the axial direction and the radial direction at the same time, which is unique. The large-flow water-taking pump pipeline and a water-throwing device reverser have their own characteristics.

Description

technical field [0001] The invention relates to a control method of water flow used for environmental protection and landscaping, which is a new type of garden watering timer with large flow rate, including a water intake pump pipeline, a double selection pumping pool tap water valve, a sprinkler and an intelligent swing Sprinklers, soil humidity measuring and controlling devices, joints capable of fine-tuning the size and pitch of threaded rings, and their matching with energy-saving sprinkler timers and sprinklers with multi-purpose interfaces. 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 mechan...
