Safe and convenient plant infusion device

Abstract

The invention relates to a safe and convenient plant infusion device which comprises a needle tubing, a liquid storage capsule, a ventilating turnover cover and a ventilating thin film. One end of the liquid storage capsule is connected with the needle tubing, and the other end of the liquid storage capsule is connected with the ventilating turnover cover. The ventilating thin film is mounted on the ventilating turnover cover. In the use process, the needle tubing is firstly communicated with the liquid storage capsule, then the needle tubing is inserted into a plant stem, finally the ventilating turnover cover is opened, air permeates the ventilating thin film to enter the liquid storage capsule, pressure in the liquid storage capsule is consistent with air pressure, and liquid in the infusion device is slowly pressed into a plant under the action of air pressure. Compared with the prior art, the safe and convenient plant infusion device has the advantages that operation is safer, the device is lighter, and liquid residues are not likely to be generated.

Description

technical field [0001] The invention relates to a plant infusion device, in particular to a safe and convenient plant infusion device. Background technique [0002] Existing plant infusion devices generally consist of a needle tube, a pressure chamber, a pressure button or a knob. When in use, the consumer needs to insert one end of the needle tube into the pressure chamber and the other end into the plant stem, then press the pressure button or turn the pressure button to increase the pressure inside the pressure chamber; at this time, the liquid inside the pressure chamber will be under high pressure and Under the double action of gravity, it slowly penetrates into the plant body to achieve the effect of pesticide application. For this type of plant infusion device, the pressure of the pressure chamber will gradually decrease with the loss of the liquid medicine. When the pressure decreases to a certain level, the liquid medicine can no longer be injected into the plant, ...

AI Technical Summary

Problems solved by technology

For this type of plant infusion device, the pressure of the pressure chamber will gradually decrease with the loss of the liquid medicine. When the pressure decreases to a certain level, the liquid medicine can no longer be injected into the plant, which will easily cause a large amount of liquid residue; pressure The pressure of the cavity is high in the initial use, and it is prone to explosion hazards during use; in order to solve the problem of residual liquid in the product, generally the pressure cavity will be filled with 1 / 2 volume of air, which increases the packaging cost of the product and is not environmentally friendly
