Device for automatically supplementing water to plants by utilizing gravity, surface tension and atmospheric pressure balance principle

Abstract

The invention discloses a device for automatically supplementing water to plants by utilizing a gravity, surface tension and atmospheric pressure balance principle, and belongs to the technical field of agricultural irrigation. The device comprises a composite structure of a water pipe and a micro water outlet (the inner diameter is smaller than 10mm), and the upper end of the water pipe is closed or consists of a detachable plug or a valve and a liquid storage structure. When plant roots contact with the water outlet and absorb water, the water at the water outlet is reduced, the diameter of the water pipe is large, the surface tension is relatively weakened due to the increase of the contact area, the gravity cannot be effectively counteracted, a water column descends, and water replenishing is achieved. The device can automatically run after being buried near the root of a plant, and the problems of energy dependence and water resource waste of an irrigation system are solved.

Description

Technical Field

[0001] The present invention relates to the technical field of agricultural irrigation, in particular to a device for automatically replenishing water to plants by utilizing the balance principle of gravity, surface tension and atmospheric pressure. Background Art

[0002] Current automatic irrigation systems primarily rely on electronic sensors or timing control technology, which can lead to high power consumption and complex equipment maintenance. Traditional manual or flood irrigation methods, on the other hand, expose water directly to the ground, resulting in high evaporation losses and low water resource utilization. This innovative invention utilizes a purely physical structure to achieve precise water control. By placing the water replenishment terminal directly in the plant root zone, the water transport path completely avoids surface evaporation, minimizing evaporation losses and fundamentally addressing the irrigation system's energy dependency and water waste. Summary of the Invention

[0003] The structure of the present invention is a composite structure of a water pipe and a micro water outlet (with an inner diameter less than 10 mm). The upper end of the water pipe is closed or consists of a detachable plug or a valve plus a liquid storage structure.

[0004] Working Principle: At the outlet, capillary action (surface tension) generated by the contact surface between the water and the pipe wall assists atmospheric pressure in supporting the weight of the water column, preventing it from flowing out naturally. When plant roots contact the outlet and absorb water, the amount of water at the outlet decreases. Due to the larger diameter of the pipe, the surface tension is relatively weakened due to the increased contact area, making it unable to effectively offset gravity. The water column then descends, achieving automatic water replenishment. DETAILED DESCRIPTION Just bury the water outlet of the device near the roots of the plants.
