Multifunctional energy-saving water sprinkler

Abstract

The invention relates to a multifunctional energy-saving water sprinkler which is a control method of water irrigation used in environmental protection and landscaping. The multifunctional energy-saving water sprinkler has the beneficial effects of being not only convenient to operate, but also enlarging an application range. By utilizing a principle that a pitch of a steel wire is diminished, but a diameter of a spring is enlarged when the spring is compressed, the side faces of multiple clamping springs (48) enable multiple fine-tuning screw thread rings (41) to not only reduce intervals among all the ring layers along with the diminishment of the steel wire, that is to say, reduce a screw pitch, but also to extrude the multiple fine-tuning screw thread rings (41) radially along with the enlargement of the diameters of the multiple springs to enable the multiple fine-tuning screw thread rings (41) to be close to a center, so that the multifunctional energy-saving water sprinkler can move in an axial direction and in the radial direction. The connected water sprinkler has eight optional water-saving water types including a right cylinder type, a cone-shaped type, a sector-shaped type, a mist spraying type, an air bubble type, a raining type, a needle-shaped type and a pulse type.

Description

technical field [0001] The invention relates to a control method for water flow used in environmental protection and landscaping. It is a multifunctional energy-saving sprinkler, a timer and a sprinkler with a joint that can fine-tune the size and pitch of the threaded ring, especially in the new The improvement on the basis of the mechanical timer with auxiliary spring and the unique elimination of the stainless steel long axis, the control on both sides of the large tube and the energy-saving sprinkler timer with multi-purpose interface is a possible improvement for timers and sprinklers. Improvements in joints for fine-tuning threaded ring size and pitch. 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 a...

AI Technical Summary

Problems solved by technology

Although the mechanical timer is widely used because of its firm structure, strong weather resistance, reliable use, and excellent cost performance, the two ends of the double gear shaft (11) are respectively set in the two oblong holes of the mechanical timer frame. However, only one end has an auxiliary spring, and the other end does not have an auxiliary spring, which lacks the proper balance moment. Therefore, during torsion and operation, the double gear shaft (11) and the meshing main gear shaft (15) cannot Parallel, there are potential hidden dangers of long-term operation wear resistance and stability

Furthermore, due to structural problems, the main control valve and pilot valve are set on one side of the main channel, and the mechanical timer is set on the other side of the main channel, causing the mechanical timer to be far away from the main channel it should directly control. Control valves and pilot valves have to be pushed out remotely with long stainless steel rods, which not only results in higher requirements for manufacturing tolerances and precision, but also causes occasional Euler instability of the pressure rod during long-term use; It also causes the long stainless steel rod to be exposed and penetrated in the main channel, and it is easy to rust and adhere to hinder the movement; in addition, the long stainless steel rod penetrates through the main channel and has a problem of sealing and leakage over time

And because, the described main control valve and pilot valve are arranged on one side of the main passage, and the scheme of setting the mechanical timer on the other side of the main passage is to set the main control valve far away from the conventional idea. And the pilot valve and main channel are immobile relative to the main body of the mechanical timer, so the remote main control valve pilot valve and main channel should be connected with the main body of the mechanical timer with a larger housing, resulting in the garden sprinkler The profile of timing switch is bigger; Simultaneously, outside the thin shaft of the main gear shaft (15) that plays a control role of mechanical timer, also have to rotate and control with very big rotary gradient circle and several parts, promptly multi-purpose part and Some aspects of the rotating gradient ring, such as the plastic square hole in the middle, are subjected to lateral torque to make the slope ring disc skew and affect the effect

To sum up, this kind of clock and watch products can be further improved, associating with some devices that the inventor once involved in manufacturing abroad, especially in Switzerland as a senior engineer SENIORENGINEER, to improve the special kneading, and then supplementing the invention to make the product Even if the timer and sprinkler are easy to use, but the interface is not good; in practice, some are pipe joints, and some are taps without threads. The method of adding more interfaces has been used. The interface is okay, but not for many interfaces; the reason is that many interfaces in a garden have been worn or corroded, and the threads of many interfaces have slipped, and they cannot be connected or tightly connected, and they still leak after connecting. The threads of many interfaces are almost the same. It is not easy to replace a large number of connections; even if they are replaced, many threads on the original water pipe also have slippery teeth, and the replaced connections will be worn or rusted, and the new connections will also be damaged. There are many problems such as upper tolerance or lower tolerance and over-tolerance that cannot be connected or not tightened and slipped teeth; there are also many problems that need to be twisted by hand tools for half a turn and then changed hands for many turns to complete a thread. Problem; Whether it is used for irrigation timers and irrigation sprinklers or others, it is desirable to have a joint that can fine-tune the size and pitch of the threaded ring for wide applicability and fast connection
