Low-cost automatic watering device for organic vegetables based on lever principle

Abstract

The invention relates to the technical field of organic vegetables, and discloses a low-cost automatic watering device for organic vegetables based on a lever principle, The automatic watering device comprises a bottom plate, wherein a shell is movably connected above the bottom plate, through cooperative use of a water inlet, a water outlet, an air bag and a piston, the air bag ascends synchronously when the water level ascends, the water inlet is closed, the water outlet is opened to irrigate the planted organic vegetables, when the water level drops, the air bag drops synchronously, the water inlet is opened, and the water outlet is closed, so that irrigation is finished, a time difference exists between opening and closing, and the purpose of regular watering can be achieved; and after the position of the air bag is adjusted, the time between opening and closing of the water inlet and the water outlet can be changed, so that different irrigation frequencies can be selected according to different growth rules and organic vegetables with different demands for water, planting of the organic vegetables is more scientific, and the practicability of the device is improved.

[0002] With the progress of society and the gradual increase of science and technology, the overall economic development of society has ushered in a huge development. However, science and technology is a double-edged sword. While technology brings development, it will also be used by many people with impure motives. More and more merchants add excessive additives or preservatives to food to improve the taste and appearance of the product, thereby attracting consumers. For example, in order to ensure the growth rate of vegetables, excessive pesticides and growth agents will be sprayed during the planting process. Long-term consumption adversely affect human health

[0003] With the attention of the society, the country has also formulated corresponding laws and regulations to restrict food safety, and different divisions are made for different food types. Among them, organic vegetables have also emerged as the times require, referring to the prohibition of using various kinds of vegetables in the process of planting Chemically synthesized pesticides, fertilizers, growth regulators and other chemical substances grow in full compliance with natural laws and are safer to eat. However, the unit price of organic vegetables in the current market is higher than that of ordinary vegetables, so more and more people will Choosing to grow vegetables at home not only reduces costs but is also safer and more secure. However, during the planting process of organic vegetables, people may forget to water due to busy work or being away from home for a long time, which will make the vegetables unable to guarantee normal water supply. Withering or even death will increase the difficulty of planting, while the traditional timed watering devices currently on the market are generally more complicated in design and cost more, which undoubtedly increases the cost of self-help organic vegetable cultivation
