Improved drip needle structure

Abstract

This invention relates to an improved drip needle structure, which is mounted on a pre-set infusion tubing and mainly includes a main rod and a control kit. The main rod has a shaft and a head fixed below the pre-set infusion tubing. The control kit includes a sleeve fitted over the shaft from bottom to top, at least one gasket, and a nut. A water flow space is formed between the sleeve and the shaft. The gasket is located above the sleeve and is pressed and positioned by the nut. The gasket can block or buffer the water flow, and the intensity of the water flow through the water flow space can be adjusted by tightening the nut, thereby achieving the functions of stable dripping and adjustable flow rate.

Claims

1. An improved drip needle structure, comprising a main rod and a control kit applied to a pre-set infusion tubing, wherein: The main pole has a head at its top. The control kit consists of a sleeve, at least one washer, and a nut that are sequentially fitted onto the pole from bottom to top. The pole passes through a hole in the at least one washer, and the inner wall of the sleeve forms a water flow space with a preset distance and is longitudinally inserted into the pole. The water in the preset infusion tube flows downward along the pole and is blocked and slightly adjusted by the at least one washer before flowing into the lower part of the pole through the water flow space to irrigate the preset plant in the corresponding preset plant carrier.

2. The improved needle structure as described in claim 1, wherein the main body has a plurality of external threads on its shaft, and the nut of the control kit has an internal thread corresponding to the external threads.

3. The improved needle structure as described in claim 1, wherein the bottom of the control kit is provided with a ring-shaped baffle.

4. The improved needle structure as described in claim 1, wherein the nut of the control kit is provided with a screw hole that fits onto the rod body.

5. The improved needle structure as described in claim 1, wherein the main rod system is a fixed component, and the sleeve and the gasket are movable components.

6. The improved needle structure as described in claim 1, wherein the number of the gaskets in the control kit can be set according to the need to adjust the water flow intensity in actual application.

7. The improved needle structure as described in claim 1, wherein the main body and the control kit are made of stainless steel.
