Abstract

An automatic watering potted plant is provided with an inner pot (containing soil and plants) in an outer pot, and the bottom of the inner pot is supported by a plurality of supporting springs; the inner pot is provided with a watering hole, and the outer pot is provided with a water stop unit, a watering trough and a watering pipe, and the water stop unit and the watering pipe are connected to a watering controller. When the soil moisture is insufficient, the supporting springs support the inner pot, so that the height of the watering hole is higher than the water stop plug, and the watering controller controls the watering pipe to discharge water, which is injected into the inner pot through the watering trough and the watering hole and seeps into the soil. The soil absorbs water, causing the total weight of the inner basin to gradually increase and move downward, compressing the support spring until the watering hole corresponds to the water stop plug and is blocked by the water stop plug. The inner basin is no longer replenished with water, and at the same time, the watering controller controls the watering pipe to stop water, and watering stops.

For ordinary technicians in this field, the specific meanings of the above terms in this creation can be understood in specific circumstances.

As shown in Figure 1, the automatic watering potted plant of this invention includes: an outer pot 10, an inner pot 12, a plurality of supporting springs 11, at least two water-stopping units 20, and a watering controller 30.

The plurality of supporting springs 11 are fixed to the bottom of the outer basin 10, and the inner basin 12 is disposed in the outer basin 10. The bottom of the inner basin 12 is evenly supported by the plurality of supporting springs 11. The outer diameter of the inner basin 12 is equal to the inner diameter of the outer basin 10, and the inner basin 12 can move up and down along the inner wall of the outer basin 10. A watering trough 13 is provided around the inner wall of the outer basin 10 near the top.

The water stop unit 20 is disposed on the wall of the outer basin 10 and corresponds to the watering trough 13. At least two watering holes 25 are disposed through the wall of the inner basin 12, and the positions of the watering holes 25 correspond to the watering trough 13 and the water stop unit 20. A watering pipe 26 is disposed on the wall of the outer basin 10 and is connected to the watering trough 13.

The watering controller 30 is connected to the water stopper 22, the watering pipe 26 and a faucet 40. The watering controller 30 controls the watering pipe 26 to stop water or discharge water.

As shown in Figures 1, 4 and 5, the water stop unit 20 includes a shell tube 21, which is fixed to the wall of the outer basin 10. A water stop plug 22 that can move back and forth is provided inside the shell tube 21, and a first compression spring 23 is provided inside the shell tube 21 to push against the second end of the water stop plug 22, so that the first end of the water stop plug 22 protrudes into the watering trough 13. The water stop plug 22 can be pushed by the outer wall of the inner basin 12 to move toward the inside of the shell tube 21, or be elastically clamped into the watering hole 25 by the tension of the first compression spring 23.

The second end of the water stopper 22 is provided with an actuating rod 24, which passes through the first compression spring 23 and the tube wall of the shell tube 21 and extends into a valve tube 31 of the watering controller 30. The actuating rod is connected to a valve member 32 in the valve tube 31. The back of the valve member 32 is pushed by a second compression spring 33, and a valve plug 34 is provided at the front of the valve member 32, and the valve plug 34 is relative to the watering tube 26.

As shown in FIG2 , the inner pot 12 is filled with soil and plants are planted. When the soil is insufficiently moist, the total weight of the inner pot 12 (the sum of the weight of the inner pot 12, the weight of the soil, and the weight of the plants) is relatively light, and the supporting spring 11 supports the inner pot 12 with its tension force. The height of the watering hole 25 of the inner pot 12 is higher than the height of the water stopper 22. The inner pot 12 pushes the water stopper 22 with its outer wall, and the water stopper 22 moves backward and compresses the first compression spring 23. The actuating rod 24 of the water stopper 22 pushes the valve member 32 backward to compress the second compression spring 33, and the valve member 32 drives the valve plug 34 to separate from the watering pipe 26. The water from the faucet 40 can enter the watering trough 13 through the watering pipe 26, and then flow into the inner basin 12 from the watering hole 25 and penetrate into the soil.

As shown in Figures 2 and 3, the soil absorbs water and the total weight of the inner basin 12 gradually increases. The inner basin 12 gradually moves downward under the weight, compressing the support spring 11 until the watering hole 25 corresponds to the water stop plug 22. The first compression spring 23 releases energy, pushes the water stop plug 22 toward the watering hole 25 and blocks it, and the inner basin 12 no longer enters the water, and watering stops. At the same time, the second compression spring 33 releases energy, and the valve 32 moves in coordination with the actuating rod 24, so that the valve plug 34 blocks the watering pipe 26, and the watering pipe 26 does not discharge water.

On the contrary, when the soil gradually dries, the total weight of the inner basin 12 gradually decreases, and the tension of the support spring 11 pushes the inner basin 12 upward gradually until the watering hole 25 leaves the water stopper 22, and the outer wall of the inner basin 12 presses the water stopper 22 to retreat, and the actuating rod 24 pushes the valve 32 backward, and the valve plug 34 disengages from the watering pipe 26, and water flows from the watering pipe 26 into the watering trough 13, and then enters the inner basin 12 from the watering hole 25, and watering is automatically performed.

In summary, the invention achieves the purpose of automatic watering and automatic watering stop by moving the inner basin 12 up and down.
