Power-free automatic irrigating device

Abstract

The invention relates to a power-free automatic irrigating device which comprises a first shell (1), a second shell (2) and a third shell (3) supporting in sequence from top to bottom, wherein an upper liquid storage cavity (A) is formed between the first shell (1) and the second shell (2), and a lower liquid storage cavity (B) is formed between the second shell (2) and the third shell (3); a uniform-speed liquid inlet (4) is formed in the first shell (1), an overflow liquid inlet (7) and an instant water supplementing opening (5) are formed in the second shell (2), and an instant irrigating opening (6) is formed in the third shell (3). The device is characterized in that the instant water supplementing opening (5) and the instant irrigating opening (6) are separately controlled to open and close through a first buoyancy valve device and a second buoyancy valve device. The power-free automatic irrigating device is simple in structure and low in cost without connecting extra apparatusessuch as a sensor, a circuit apparatus element and a control element.

Description

Technical field [0001] The invention relates to a watering device, in particular to a non-powered automatic watering device. Background technique [0002] Recently, most domestic automatic watering devices adopt single-chip microcomputer, sensor and circuit control to realize automatic irrigation; although they can realize automatic watering according to the requirements of soil moisture, they have the following problems: [0003] (1) The price is high, and additional equipment such as sensors, circuit electrical components, and control components are required; [0004] (2) It requires an external power supply, which consumes high energy, and requires intermediate components such as transmissions and converters; [0005] (3) External staff are required to manually manipulate and pre-debug relevant circuit components and control components, which is labor intensive and is prone to errors after heavy workload; [0006] (4) It is inconvenient to disassemble and assemble, and maintenance i...

AI Technical Summary

Problems solved by technology

[0003] (1) The price is high, and additional equipment such as sensors, circuit electrical components, and control components are required;

[0004] (2) An external power supply is required, which consumes a lot of energy and requires intermediate components such as transmissions and converters;

[0005] (3) External staff are required to manually manipulate and pre-adjust relevant circuit components and control components, which is labor-intensive and prone to human error after a large workload;

[0006] (4) It is inconvenient to disassemble and assemble, and difficult to maintain. When replacing, it is necessary to select related electrical components of the same model, and the scope of application is narrow;

[0007] (5) The cost of operation and maintenance is high, and it is necessary to replace, repair and calibrate the relevant electrical components regularly after a period of watering, which is time-consuming and labor-intensive and increases the cost
