Technical Field
[0001] This utility model relates to the field of irrigation device technology, specifically a circulating garden irrigation device. Background Technology
[0002] Garden irrigation is one of the important tasks in garden maintenance. Irrigation can provide garden plants with the necessary water supply, enabling them to grow healthily and vigorously.
[0003] Currently, there are two main methods of garden irrigation: sprinkler irrigation and drip irrigation. The two differ in their water output methods. Both use pumps to supply water to pipes, which then supply water to plants through sprinklers or drip irrigation holes. However, in actual use, there are some functional shortcomings that have room for improvement. For example, during irrigation, water only flows out and does not flow in. After watering, only a portion of the water is absorbed by the plants, while the remainder seeps into the soil or runs off along the surface, resulting in significant water resource loss. Furthermore, they do not have the function of collecting and recycling water.
[0004] Now, a novel circulating garden irrigation device is proposed to solve the above problems. Utility Model Content

[0007] The water collection assembly includes multiple sets of water collection trough pipes, which are fixedly connected to the left side of the underground water tank. A filter media frame is horizontally placed at the top of each water collection trough pipe, and the filter media frame has its upper and lower ends...
[0008] Each filter is fixedly connected with a stainless steel screen. An activated carbon filter layer is evenly laid at the bottom of the filter media frame. A fine sand filter layer is evenly laid at the top of the activated carbon filter layer. A granular sand filter layer is evenly laid at the top of the fine sand filter layer.
[0009] As a further technical solution of this utility model, the underground water tank and the water collection trough pipe are internally connected, and the front and rear ends of the water collection trough pipe and the filter material frame are flush.
[0010] As a further technical solution of this utility model, the activated carbon filter layer, the fine sand filter layer, and the granular sand filter layer are separated by nylon mesh, and the activated carbon filter layer, the fine sand filter layer, and the granular sand filter layer have the same thickness.
[0011] As a further technical solution of this utility model, the tops of the underground water tank and the filter frame are flush, and the outer diameter of the activated carbon filter layer and the granular sand filter layer is larger than the inner diameter of the sieve holes of the stainless steel screen.
[0012] As a further technical solution of this utility model, an ultrasonic liquid level sensor is fixedly connected to the top of the sealing cover, a water inlet pipe is provided on the right side of the water inlet interface, a first solenoid valve is installed between the water inlet interface and the water inlet pipe, the ultrasonic liquid level sensor passes through the sealing cover and extends into the inside of the water inlet pipe, and the ultrasonic liquid level sensor, the first solenoid valve, and the controller are electrically connected.
[0013] As a further technical solution of this utility model, a sludge accumulation trough is provided on the right side of the bottom of the underground water tank. The sludge accumulation trough is fixedly connected to the bottom of the right side of the underground water tank. A sludge discharge port and a sludge discharge pipe are provided on the right side of the sludge accumulation trough. A second solenoid valve is installed between the sludge discharge port and the sludge discharge pipe. The sludge accumulation trough and the sludge discharge port are internally connected. The second solenoid valve and the controller are electrically connected.
[0014] Compared with the prior art, the beneficial effects of this utility model are: the circulating garden irrigation device not only realizes the function of water collection and circulation, but also realizes the function of automatic water replenishment, and also realizes the function of easy discharge of mud and sand;
[0015] (1) The system is equipped with a water collection tank, filter frame, stainless steel screen, activated carbon filter layer, fine sand filter layer and granular sand filter layer. When in use, the underground water tank is buried underground for water storage. When irrigating, the water pump is started. The water pump draws water from the underground water tank through the water intake pipe and pumps it to each branch pipe through the water supply pipe. The nozzles at the top of the branch pipes can then spray water outwards for irrigation. After the sprayed water wets the soil, some of it seeps into the ground.
[0016] The water passes through the filter media frame and is filtered by three layers of filter media: activated carbon filter layer, fine sand filter layer and granular sand filter layer. After entering the water collection tank, the water is collected and flows back to the underground water tank. It can also collect rainwater at the same time. It has less loss in irrigation and can save water resources. The stainless steel screen can protect the filter media and realize the function of water collection and circulation.
[0017] (2) By setting up an ultrasonic level sensor, a first solenoid valve and a water inlet pipe, when in use, the water inlet pipe is connected to a faucet or other facilities on the ground. As the water in the underground water tank decreases, the ultrasonic level sensor keeps monitoring the water level. When the water level is lower than the preset threshold, the first solenoid valve automatically opens to replenish the underground water tank, thus realizing the function of automatic water replenishment.
[0018] (3) By setting up a sludge trough, a sludge discharge port, a second solenoid valve and a sludge discharge pipe, when in use, the water flowing back into the underground water tank is prone to carry some fine sand. The design of the sloping bottom of the underground water tank can collect the mud and sand in the water and let it settle in the sludge trough. By periodically opening the second solenoid valve, the mud and sand deposited in the sludge trough can be discharged through the sludge discharge port and the sludge discharge pipe, thus realizing the function of conveniently discharging mud and sand.

[0029] Specifically, as shown in Figures 1 and 2 and Figure 4 As shown, the infiltrated water passes through the filter media frame 3, where it is filtered by three layers of filter media: activated carbon filter layer 5, fine sand filter layer 6, and granular sand filter layer 7, before entering the water collection tank pipe 2.
[0030] The water is collected and returned to the underground water tank 1 through the collection trough pipe 2. It can also collect rainwater at the same time, resulting in less water loss during irrigation and saving water resources. The stainless steel screen 4 can protect the filter media.

The second solenoid valve 23 and the controller 25 are electrically connected. This technology is existing technology and will not be described in detail here.
[0035] Working Principle: In use, the underground water tank 1 is first buried underground for water storage. During irrigation, the water pump 11 is activated, drawing water from the underground water tank 1 through the water intake pipe 12. This water is then pumped through the water supply pipe 8 to various branch pipes 9. The nozzles 10 at the top of the branch pipes 9 spray water outwards for irrigation. After wetting the soil, some of the sprayed water seeps down. This seeping water passes through the filter media frame 3, where it is filtered by three layers of filter media: activated carbon filter layer 5, fine sand filter layer 6, and granular sand filter layer 7. The filtered water then enters the water collection trough pipe 2, where it is collected and flows back into the underground water tank 1. Rainwater can also be collected simultaneously. This method minimizes water loss during irrigation and conserves water resources. The stainless steel screen 4 protects the filter media. The water inlet pipe 20 connects to the ground surface.
[0036] As the water level in the underground water tank 1 decreases, facilities such as faucets are monitored by the ultrasonic level sensor 18. When the water level falls below a preset threshold, the first solenoid valve 19 automatically opens to replenish the underground water tank 1. The water flowing back into the underground water tank 1 may carry some fine sand. The sloping design at the bottom of the underground water tank 1 helps collect the sediment, allowing it to settle in the sediment collection trough 21. Periodically opening the second solenoid valve 23 allows the sediment deposited in the sediment collection trough 21 to be discharged through the sediment discharge port 22 and the sediment discharge pipe 24.
