Problems solved by technology

[0002] Drip irrigation is an advanced water-saving irrigation technology. The existing irrigator has only one water outlet hole, and its flow rate cannot be adjusted. However, the water demand of crops in different growth periods is different, that is, the irrigator should meet the needs of different crops. The flow rate can be changed according to the water demand, but because the existing emitter has only one water outlet hole, and the hole diameter cannot be changed, the flow rate can only be changed by changing the pressure of the water supply system, or prolonging the water supply time, which increases energy consumption

Embodiment Construction

[0005] The present invention will be described in detail in conjunction with the above drawings. The emitter of the present invention is composed of an inner cavity 1 and a housing 2. The thread on the outer surface of the inner cavity matches the threaded hole of the housing, and the inverted tooth body at the upper end matches the water supply The tubes are connected, and the lower end of the shell is provided with a cylinder whose end is a cone. The axial hole in the cylinder communicates with the axial hole in the inner cavity, and the radial hole and the axial hole are opened on the hole wall of the cylinder. The holes are connected; in order to reduce the resistance of the emitter to the soil, the upper part of the cylinder section of the shell is made into a rhombus-shaped shell in cross section, and radial holes are opened on the hole walls of different heights in the lower part of the rhombus-shaped shell. The hole communicates with the axial hole in it.

Abstract

The invention discloses a douche, relating to a watering device, and aims at providing a douche with adjustable flow rate. The invention has the technical scheme that: the douche comprises a douche housing, an inner axial hole and a radial hole, wherein the radial hole of the housing is a screwed hole matched with the outside threads of the inner cavity body, the upper end of the inner cavity is a reversed dentiform pipe matched with a water supply pipe, the lower tip of the housing is a pointed conical body, and the lower end of the housing is provided with a section of nonscrewed blind hole communicated with the screwed hole of the housing; and the walls of the blind hole and the screwed hole are provided with radial water outlet holes, and at least one radial water outlet hole is arranged at the wall of the lower part of the screwed hole of the housing along an axial direction. The douche is used for irrigation.

Description

Technical field: [0001] The invention relates to a watering device, in particular to a sprinkler. Background technique: [0002] Drip irrigation is an advanced water-saving irrigation technology. The existing irrigator has only one outlet hole, and its flow rate cannot be adjusted. However, the water demand of crops in different growth periods is different, that is, the irrigator should meet the needs of different crops. The flow rate can be changed according to the water demand, but because the existing emitter has only one water outlet hole, and the hole diameter cannot be changed, the flow rate can only be changed by changing the pressure of the water supply system, or prolonging the water supply time, which increases energy consumption. Invention content: [0003] The object of the present invention is to provide an emitter with variable flow. The technical solution of the present invention is an emitter comprising an emitter housing and its inner axial hole and radia...
