Water saving method for rotary water sprayer with wide range

Abstract

The invention relates to a water saving method for a rotary water sprayer with a wide range. The method is characterized by comprising a rotary water sprayer (59), a spraying head of the rotary water sprayer is rotary, and the heights from bottom to top of the groove bottoms of a right water spraying groove and a left water spraying groove in water spraying grooves of the rotary water sprayer are different to form the rotary water sprayer with the wide range. Arc grooves of the rotary water sprayer are respectively contour line grooves of which the parabolas are smoothly connected in a central arc equation manner and the cross sections are in wing shapes, the heights of the two groove bottoms are different, and the distance between two water throwing grooves is different, so that the rotary water spraying with axial flow and wide range is convenient. Function curves are adopted in multiple positions, so that the product quality is improved; an inner wall which is provided with a plurality of through holes and is arranged at the side part of a spraying head cap adopts a cube curve with the function of a buffering curve in the middles of a straight passage and a circular arc-shaped water passage, and the impact is alleviated when water flow turns; a rib is arranged between every two through holes, the rib is in an equal angle spiral shape, i.e. a logarithmic spiral shape, and the water can be uniformly sprayed because pressure angles are the same in any place; the batched quality of the product is further improved by the spraying head cap with a cube curve water passage and the equal angles spiral rib and a spraying head seat with a hyperbolic curve pipeline or a logarithmic spiral pipeline.

Description

technical field [0001] The invention relates to a method for controlling water flow for environmental protection and landscaping, which is a water-saving method including a wide-width rotary sprinkler, with movable and fixed sprinklers, including a new type of 360-degree sprinkler, a rotary sprinkler, and an adjustable sprinkler. The connector for fine-tuning the size and pitch of the threaded ring, and its matching with the energy-saving sprinkler timer and water distributor with multi-purpose interfaces are used for efficient irrigation and water saving. 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 ...

Problems solved by technology

Existing products vary, and none of them are perfect; there is a certain nozzle (55ac), such as Figure 31 As shown, the water is connected to the nozzle seat (55c) of the certain nozzle (55ac) through the matching components and then sprayed out through the only small square hole provided on the nozzle cap as the water nozzle (55a3c). Its disadvantage is that the range of sprayed water is narrow, and it cannot have a 360-degree all-round irrigation effect.

Another nozzle (55ad) for existing products, such as Figure 32 As shown, the water is connected to the nozzle seat (55c) of the certain nozzle (55ad) through the matching components, and is sprayed out through the large through hole opened on the half side of the nozzle cap as the water nozzle (55a3d) , its shortcoming is that the range of sprayed water is only half, and cannot have a 360-degree all-round irrigation effect

The nozzle cap (55ab) of another nozzle of the preliminary improved product, such as Figure 29 As shown, the water is connected to the nozzle seat and the movable nozzle ball of the certain nozzle (55ab) through the matched parts, and passes through the multiple through holes around the ring set on the nozzle cap as the water nozzle (55a3). In order to make the water balance and self-regulation, it is desirable to set a movable nozzle ball in the center of the nozzle, but because the center of the inner top of the nozzle cap is provided with a cone pointing downwards, that is, towards the nozzle ball, although the ball can be moved Free and easy to control, but the tip of the cone tends to be biased against the movable nozzle ball. The water spray of another nozzle of the preliminary improved product is still insufficient, and the range of water sprayed is only half. Can not have 360-degree all-round irrigation effect
