Description

Technical Field

[0001] This utility model relates to the technical field of automatic irrigation control devices, and in particular to a multi-valve irrigation controller structure. Background Technology

[0002] Automatic irrigation devices are frequently used in agricultural facilities, courtyards, or balcony planting. These automatic irrigation devices are also known as timed automatic watering controllers. The automatic irrigation devices are equipped with water pipes, solenoid valves, and control circuits that control the automatic opening and closing of the solenoid valves. By setting the relevant parameters in the control circuit, automatic timed irrigation can be achieved, making it convenient for users to remotely manage the system without human intervention.

[0003] Existing automatic irrigation devices typically have one inlet pipe and one or two outlet pipes; that is, an automatic irrigation device can usually only control two water outlets simultaneously. If more outlet pipes are added, the conventional straight-through fluid cross-section structure, limited by the internal piping structure, can easily reduce the water pressure at the far outlet pipes, affecting the irrigation effect. Therefore, the structure of the automatic irrigation device needs to be improved so that it can meet the water output requirements of four outlet pipes simultaneously, making it convenient for users. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a multi-valve irrigation controller structure. By improving the internal piping and main installation structure of the automatic irrigation device, it facilitates the centralized installation of four solenoid valves, enabling simultaneous control of four water outlet pipes for irrigation. This better ensures the water output requirements of the water outlet pipes and makes it easier for users to operate.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A multi-valve irrigation controller structure includes a housing and a control circuit, a solenoid valve, and a water valve seat disposed within the housing. The water valve seat includes an inlet pipe, a transverse connecting pipe, and four independent outlet pipes. The input end of the inlet pipe protrudes from one end of the housing, and the output ends of the four independent outlet pipes protrude from the other end of the housing. The inlet pipe is vertically disposed in the middle of the transverse connecting pipe. The transverse connecting pipe has two parallel water passages connected to the inlet pipe. The transverse connecting pipe has four mounting seats, and the solenoid valve is mounted and connected to each mounting seat. The transverse connecting pipe corresponding to each mounting seat has a cylindrical tube that is sealed and connected to the output port of the solenoid valve. The upper end of the cylindrical tube and the inner side of the mounting seat have an annular water passage.

[0006] Furthermore, one end of the two parallel water passageways is closed, and the other end of the water passageways is provided with a process opening.

[0007] Furthermore, the process opening is provided with a sealing end cap.

[0008] Furthermore, the main cross-section of the transverse connecting pipe is semi-circular, and the two water passages are symmetrically arranged on both sides inside the transverse connecting pipe.

[0009] Furthermore, two of the mounting seats are disposed on the transverse connecting pipe on one side of the water inlet pipe, and two other mounting seats are symmetrically disposed on the other side of the transverse connecting pipe.

[0010] Furthermore, a process groove is provided between the two mounting seats on the same side of the transverse connecting pipe.

[0011] Furthermore, the housing is provided with a mounting compartment for sealing and mounting the control circuit, and the mounting compartment is provided with a sealing cover.

[0012] Furthermore, the outer casing includes an upper cover and a lower cover, and the upper cover and the lower cover are respectively provided with positioning slots corresponding to the water inlet pipe and the four water outlet pipes.

[0013] This utility model has the following beneficial effects: 1. This utility model improves the structure of the water valve seat in the automatic irrigation device by setting two parallel water passages in the water valve seat to facilitate large flow of water, making it easy to centrally install four solenoid valves, which can simultaneously control four water outlet pipes for irrigation, better ensure the water output requirements of the water outlet pipes, and facilitate user operation.
