Description

Technical Field

[0001] This utility model is an irrigation timer that can measure flow rate, belonging to the field of irrigation timer technology. Background Technology

[0002] An irrigation timer is a device that automatically controls the start and stop of an irrigation system by preset time parameters. Its core functions include timed and quantitative watering, flexible setting of multiple time periods, automatic stop by rain sensing, remote control and intelligent linkage. It is suitable for various scenarios such as home gardening, agricultural planting and public greening, and can significantly improve irrigation efficiency and save water resources. Existing irrigation timers typically lack metering functionality, making it impossible to determine the water flow rate. Furthermore, irrigation timers are usually battery-powered, which is prone to voltage issues. Since most irrigation timers are installed outdoors, they are susceptible to lightning strikes during thunderstorms. Therefore, to address these issues, a flow-measuring irrigation timer is proposed. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an irrigation timer that can measure flow rate in order to solve the existing problems.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: an irrigation timer capable of measuring flow rate, the structure of which includes an outer shell, a top cover on the outer shell, the top cover being integrally formed with the outer shell, a main control module in the inner cavity of the outer shell, a display screen connected to the outer shell, the display screen being connected to and controlled by the main control module, an inspection port below the display screen, and a water pipe connected to the outer shell, one end of the water pipe extending into the inner cavity of the outer shell and connected to an external water outlet, and the other end of the water pipe being connected to an external sprayer.

[0005] Furthermore, the main control module is connected to a control module, a power module, and a water flow meter. The power module is used to supply power, and the monitoring end of the water flow meter is connected to the water pipe. Both the main control module and the control module are conventional chips used in this device, so they will not be described in detail.

[0006] Furthermore, the control module is connected to an electronic valve, which is connected to the water pipe.

[0007] Furthermore, a boost module is connected to the power module, such as... Figure 4As shown, a P-channel MOSFET is added at the output enable point for isolation, which can prevent output voltage when the circuit is not working. A PWM (Pulse Width Modulation) wave is applied at the program drive point. The waveform frequency and pulse width duty cycle are adjusted by the program to achieve the required output voltage. The ADC (Analog-to-Digital Converter) is used in the program to read the voltage value at the output voltage point, thereby adjusting the PWM wave frequency and pulse width duty cycle to achieve the purpose of feedback voltage regulation.

[0008] Furthermore, a metal mesh is embedded in the inner cavity of the top cover, and the top cover is made of a non-metallic material.

[0009] The beneficial effects of this utility model are: By installing a water flow meter, the water flow rate can be monitored in real time; By connecting a boost module to the battery module, the output voltage can be boosted when the battery module is supplying power, and the output voltage can be turned off when the battery module is not supplying power, thereby saving power. Furthermore, the boost module can output different voltage values ​​according to the actual power consumption requirements. By reading the output voltage value and then adjusting it accordingly, the voltage stabilization purpose can be achieved. By embedding a metal mesh in the top cover, the Faraday cage effect is created by utilizing the conductivity of the metal to shield external electromagnetic fields, thereby protecting the internal components.

[0013] Please see Figures 1-4This utility model provides a technical solution for an irrigation timer that can measure flow rate: its structure includes an outer shell 1, a top cover 2 on the upper part of the outer shell 1, the top cover 2 being integrally formed with the outer shell 1, a main control module in the inner cavity of the outer shell 1, a display screen 3 connected to the outer shell 1, the display screen 3 being connected to and controlled by the main control module, an inspection port 4 below the display screen 3, and a water pipe 5 connected to the outer shell 1, one end of the water pipe 5 extending into the inner cavity of the outer shell 1 and connected to an external water outlet, and the other end of the water pipe 5 being connected to an external sprayer; The main control module is connected to a control module, a power module, and a water flow meter. The power module is used to supply power. The monitoring end of the water flow meter is connected to the water pipe 5. The control module is connected to an electronic valve, which is connected to the water pipe 5. The power module is connected to a boost module.
