Description

Gravity opening and closing type automatic irrigation device Technical Field The invention relates to the technical field of watering irrigation, in particular to a gravity-opening and closing type automatic irrigation device. Background Potted plants are taken as an independent planting unit, and the green planting of the potted plants becomes an important carrier for improving the air quality in families, offices and scientific research objects. However, the traditional potting irrigation method is mostly dependent on manual regular watering, and has the obvious problems that firstly, plant water shortage or excessive watering is easily caused by human negligence to influence plant health, secondly, stable irrigation is difficult to maintain when a business trip or long-time going out, and thirdly, the existing automatic irrigation system (such as electronic regular drip irrigation, soil humidity sensor control and the like) is dependent on electric power or battery driving, and has the limitations of high energy consumption, complex maintenance, high cost and the like. Most gravity irrigation equipment relies on manual adjustment of a fixed water storage container and a valve, and cannot respond dynamically according to the actual water demand of soil, so that water resource waste or unbalanced irrigation is caused. Aiming at the problems, the gravity-operated automatic irrigation potting device provided by the invention creatively realizes closed-loop control of irrigation on-off through gravitational potential energy and container weight change. The method is characterized in that when the integral weight of the potted plant is reduced to a threshold value due to the evaporation of water and the transpiration of plants, the reverse gravity triggers the opening of an irrigation mechanism, external water storage flows into soil under the action of gravity, the total weight of the potted plant is risen after water is supplemented, and the gravity automatically closes irrigation, so that the repeated automatic irrigation flow is realized. Meanwhile, the invention can realize the adjustable opening time of each automatic irrigation through a mechanical structure, namely control the irrigation period, thereby meeting the difference of drought tolerance of different plants, and can also adjust the irrigation quantity of each automatic irrigation to meet the difference of different water requirements of different plants, and avoid the situation that rotten roots and roots are too much in water and cannot breathe. Disclosure of Invention Aiming at the defects of the prior art, the invention provides a gravity-opening-closing type automatic irrigation device which is used for meeting the water control of one planting unit, changing the current situation of manual regular watering and providing convenience and periodicity for regular irrigation of water of one planting unit related to indoor plant cultivation and scientific research.
