Abstract
Description
Technical Field
[0001] This utility model relates to the field of horticultural energy conservation and environmental protection technology, and more specifically, to a water-saving irrigation device. Background Technology
[0002] With the improvement of people's living standards, potted plants have been widely used in indoor and outdoor environmental decoration and air quality improvement. However, watering potted plants has always been a process that requires precise control. Existing manual watering methods have many drawbacks. On the one hand, it is difficult for people to accurately judge the actual water needs of the potted soil, often resulting in overwatering or underwatering. Overwatering can easily lead to waterlogging, causing root rot due to lack of oxygen, affecting plant growth and even causing plant death; underwatering will cause the plant to suffer from drought, which is also detrimental to the plant's healthy growth. On the other hand, manual watering relies on personal experience and time management, and busy modern people often forget or neglect to water their potted plants in time.
[0003] Furthermore, in some public places, such as office buildings, hotel lobbies, and shopping malls, a large number of potted plants are placed. Manual watering not only consumes manpower and time but also results in significant water waste. Therefore, developing a water-saving irrigation device that can accurately detect soil moisture in potted plants, achieve automatic quantitative irrigation, and effectively reduce water waste is of great practical significance. Utility Model Content
[0004] (a) Purpose of the utility model
[0005] To address the shortcomings of existing methods, the purpose of this invention is to provide a water-saving irrigation device that uses a soil moisture sensor to detect the soil moisture in potted plants in real time and combines it with a control system to achieve automatic quantitative irrigation. This solves the problems of inaccurate watering, water waste, and reliance on manual labor in existing potted plant irrigation methods, providing a suitable growth environment for potted plants while reducing maintenance costs.
[0006] (II) Technical Solution
[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0008] A water-saving irrigation device includes a water storage tank and a support frame. The support frame is a frame structure, with the water storage tank fixed to its upper end by a steel strap. The water storage tank has a water inlet on its front side. Multiple sets of water outlet pipes are evenly distributed longitudinally at the bottom of the water storage tank. A solenoid valve and a flow sensor are sequentially mounted on each water outlet pipe from top to bottom. A water delivery hose is sealed to the bottom of one set of water outlet pipes. The left end of the water delivery hose is connected to a fixed water pipe through a sealed joint. An integrated irrigation ring pipe is provided at the left end of the fixed water pipe. Multiple sets of water outlet pipes are evenly distributed at the bottom of the irrigation ring pipe. A control box is fixedly connected to the right end of the fixed water pipe. A hook is provided on the left side of the control box. A sliding sleeve is vertically fixed on one side of the fixed water pipe. A sliding and adjustable positioning rod is inserted inside the sliding sleeve. A soil moisture sensor is installed at the lower end of the positioning rod.
[0009] Furthermore, the irrigation ring pipe has a three-quarter circular structure, with its opening facing to the left.
[0010] Furthermore, the water inlet is fitted with a removable sealing cap via a threaded seal, and a pressure balance port is provided on the left side of the upper end face of the water storage tank.
[0011] Furthermore, the upper right side of the water storage tank is provided with a water injection pipe for connecting to an external water pipe, and the water injection pipe is equipped with a manual valve for controlling the switch.
[0012] Furthermore, a transverse partition is longitudinally fixed at the middle position on both the left and right sides of the support frame, and multiple sets of slots adapted to the water delivery hose are evenly opened on the upper surface of the transverse partition.
[0013] Furthermore, a wire mesh frame for storing items is placed on the inner bottom of the support frame, and multiple sets of self-locking swivel casters are evenly distributed on the bottom of the support frame.
[0014] (III) Working Principle
[0015] In actual use, add water to the water tank through the water inlet or water pipe, then hang the hook on the edge of the flowerpot and secure the irrigation ring to the main stem of the plant. Press down the positioning rod to insert the soil moisture sensor into the soil, positioning it 1-5cm away from the plant roots. Next, connect one end of the water delivery hose to the fixed water pipe and the other end to a water outlet pipe.
[0016] Users can select the type of potted plant and set the corresponding humidity threshold via the touch screen on the controller. A soil moisture sensor monitors the actual soil moisture around the plant roots in real time. When the detected humidity is below the lower threshold, the microprocessor determines "irrigation is needed" and issues a start command; when the detected humidity reaches the upper threshold, the microprocessor determines "irrigation is sufficient" and issues a stop command.
[0017] The microprocessor's start command triggers the solenoid valve on the corresponding outlet pipe to open. Water from the storage tank flows through the outlet pipe, water delivery hose, and fixed water pipe into the irrigation loop, then flows out through the outlet hole and is sprayed onto the soil for irrigation. A flow sensor on the outlet pipe monitors the water flow data in real time and feeds it back to the microprocessor, forming a closed-loop control system. The microprocessor determines the irrigation amount based on the flow data to avoid over-watering. When the soil moisture sensor detects that the moisture level has reached the upper limit threshold, the microprocessor issues a stop command, the solenoid valve closes, and irrigation terminates.

[0032] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.
[0033] Example:
[0034] like Figures 1 to 7As shown, a water-saving irrigation device includes a water storage tank 1 and a support frame 2. The support frame 2 is a frame structure, with the water storage tank 1 fixed to its upper end by a steel strap for storing the water required for irrigation. A water inlet 16 is provided on the front side of the water storage tank 1 for replenishing water. Multiple sets of water outlet pipes 21 are evenly distributed longitudinally at the bottom of the water storage tank 1, enabling independent water supply from multiple points to meet the irrigation needs of different potted plants. From top to bottom, each water outlet pipe 21 is equipped with a solenoid valve 23 and a flow sensor 22 to control the water flow switch and monitor the flow rate. The solenoid valve 23 enables precise start and stop, and the flow sensor 22 provides real-time feedback of water volume data, forming a closed-loop control to avoid over-irrigation and save water resources. A water delivery hose 3 is sealed to the bottom of one set of water outlet pipes 21. The left end of the water delivery hose 3 is connected to a fixed water pipe 10 through a sealed connector. The left end of the fixed water pipe 10... An integrated irrigation ring pipe 4 is provided, with multiple sets of water outlet pipes 21 evenly distributed at the bottom of the irrigation ring pipe 4 for spraying water into the flower pot. A control box 11 is fixedly connected to the right end of the fixed water pipe 10 for receiving and processing the electrical signal generated by the soil moisture sensor 7. A hook 12 is provided on the left side of the control box 11 to facilitate hanging the control box 11 and the irrigation ring pipe 4 at the edge of the pot for easy and quick installation and disassembly. A sliding sleeve 9 is vertically fixed on one side of the fixed water pipe 10, and a sliding and adjustable positioning rod 8 is inserted inside the sliding sleeve 9. The soil moisture sensor 7 is installed at the lower end of the positioning rod 8. The positioning rod 8 facilitates the insertion of the soil moisture sensor 7 into the soil. By adjusting the height of the positioning rod 8, the soil moisture sensor 7 can adapt to the soil depth of different pots, monitor the soil moisture in real time, trigger the irrigation program, and realize on-demand water supply.
[0035] It should be noted that the soil moisture sensor 7 is inserted into the soil of the potted plant, 1-5cm away from the plant roots. This position can accurately reflect the actual moisture level of the soil around the plant roots.
[0036] In this embodiment, the irrigation ring pipe 4 has a three-quarter circular structure with its opening facing to the left. The annular opening design allows the irrigation ring pipe 4 to be fitted onto the main stem of the plant, so that the water flow can evenly cover the root area at the bottom of the main stem of the plant, thereby improving the uniformity of irrigation.
[0037] In this embodiment, a removable sealing cap is fitted to the water inlet 16 by a threaded seal to prevent impurities from entering the water storage tank 1 and ensure airtightness. An air pressure balance port 14 is provided on the left side of the upper end face of the water storage tank 1 to balance the internal and external air pressure difference and realize water inlet and outlet.
[0038] In this embodiment, a water inlet pipe 17 for connecting to an external water pipe is provided on the right side of the upper end face of the water storage tank 1. A manual valve 18 for controlling the switch is installed on the water inlet pipe 17. The water inlet pipe 17 is connected to an external faucet through an external water pipe to realize automatic water replenishment, reduce manual operation, and at the same time, it works with the water inlet 16 to realize dual-channel water replenishment, improving the flexibility of use.
[0039] In this embodiment, horizontal partitions 19 are longitudinally fixed at the middle positions on both the left and right sides of the support frame 2. Multiple sets of slots 20 adapted to the water supply hose 3 are evenly opened on the upper surface of the horizontal partitions 19. This design is used to fix the water supply hose 3, prevent the hose from tangling or falling off, and improve pipeline management efficiency.
[0040] In this embodiment, a wire mesh frame 5 for storing items is placed on the bottom inner side of the support frame 2. This is used to store gardening supplies, increase storage space, and improve practicality. Multiple sets of self-locking omnidirectional casters 6 are evenly distributed on the bottom of the support frame 2 to enable the device to move and be fixed, allowing the device to be flexibly moved to different positions.
[0041] It should be noted that the soil moisture sensor 7 is electrically connected to the sub-control box 11 via wires. The sub-control box 11 contains a power module, a wireless signal transmitting module, and a signal processing module. The controller 15 contains a power module, a microprocessor, and a wireless signal receiving module. The controller 15 also has a touch screen display on its front side. The signal processing module receives the electrical signal from the soil moisture sensor 7 and transmits the data to the microprocessor via the wireless signal transmitting and receiving modules. The microprocessor receives the electrical signal from the soil moisture sensor 7 and converts it into a digital signal for processing.
[0042] The microprocessor has preset suitable soil moisture ranges for different plant species. Users can select the type of potted plant via the device's touch screen, and the microprocessor determines the corresponding moisture threshold based on the user's selection. When the detected soil moisture is lower than the set lower threshold, the microprocessor issues an irrigation start command; when the soil moisture reaches the set upper threshold, the microprocessor issues an irrigation stop command.
[0043] In addition, the controller 15 is equipped with a data storage module that can record changes in soil moisture over a period of time. Users can view historical data through the operation interface to better understand the growth status and irrigation needs of potted plants.
[0044] The working principle of this water-saving irrigation device:
[0045] In actual use, water is added to the water tank 1 through the water inlet 16 or the water pipe 17. Then, the hook 12 is hung on the edge of the flowerpot, and the irrigation ring pipe 4 is clipped onto the main stem of the plant. The positioning rod 8 is pressed down, and the soil moisture sensor 7 is inserted into the soil, positioned 1-5 cm away from the plant roots. Next, one end of the water delivery hose 3 is connected to the fixed water pipe 10, and the other end is connected to a water outlet pipe 21.
[0046] Users can select the type of potted plant and set the corresponding humidity threshold via the touch screen on the controller 15. The soil moisture sensor 7 monitors the actual soil moisture around the plant roots in real time. When the detected humidity is below the lower threshold, the microprocessor determines that "irrigation is needed" and issues a start command; when the detected humidity reaches the upper threshold, the microprocessor determines that "irrigation is sufficient" and issues a stop command.
[0047] The microprocessor's start command triggers the solenoid valve 23 on the corresponding outlet pipe 21 to open. Water from the storage tank 1 flows through the outlet pipe 21, the water delivery hose 3, and the fixed water pipe 10 into the irrigation ring pipe 4, and then flows out through the outlet hole 13, spraying it onto the soil to achieve irrigation. The flow sensor 22 on the outlet pipe 21 monitors the water flow data in real time and feeds it back to the microprocessor, forming a closed-loop control. The microprocessor determines the irrigation amount based on the flow data to avoid over-watering. When the soil moisture sensor 7 detects that the moisture has reached the upper limit threshold, the microprocessor issues a stop command, the solenoid valve 23 closes, and irrigation ends.
[0048] Through the above process, the device achieves on-demand and quantitative irrigation, only starting when the soil moisture around plant roots is insufficient. It also precisely controls the water volume through flow monitoring and threshold control, reducing water waste, while taking into account both operational flexibility and irrigation uniformity.
[0049] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
