Detailed Description
Example 1
As shown in fig. 1-2, the flower watering device comprises a shell 1, a partition plate 2 is arranged in the shell 1, the shell 1 is divided into a first cavity 3 and a second cavity 4 by the partition plate 2, and a through hole 5 communicating the first cavity 3 and the second cavity 4 is formed in the middle of the partition plate 2; the first cavity 3 is connected with a gland 7 through a first elastic piece 6, and a water outlet 8 is formed on the first cavity 3 by matching with the gland 7; a water inlet hole 9 and a flower watering hole 10 are formed on the second cavity 4; a piston structure is connected in the second cavity 4 through an inner elastic piece 11; the water outlet 8 of one watering device is communicated with the water inlet 9 of the other watering device. A stop 13 is formed in the first chamber 3 to cooperate with the gland 7. The first cavity is not hermetically arranged, so that ventilation is facilitated, and overlarge pressure is prevented. The first elastic member 6 and the inner elastic member 11 are springs or elastic rods, preferably springs. The piston structure is a piston 12.
When water enters, water enters from the water inlet hole 9, the piston 12 is pressed backwards through water pressure, the through hole 5 is opened, the gland 7 is squeezed by the water pressure to rise, the water is accumulated in the first cavity 3, and after the gland 7 contacts the stop block 13, the water flows into the next flower watering device through the water outlet hole 8. After water supply is stopped, water pressure at the water inlet 9 disappears, at the moment, the piston 12 blocks the water inlet 9 under the pressure of the spring, the first cavity 3 is communicated with the flower watering hole 10 through the through hole 5, and water accumulated in the first cavity 3 flows into the flowerpot to water flowers. Therefore, the amount of water accumulated in each flower watering device is the same, so that the same watering amount of each flower is ensured. In order to realize quantitative watering, the position of the block can be adjusted according to the needs of different flowers, and the position and the form of the block are not limited as long as the purpose can be achieved.
Specifically, when the pressure of the water in the water inlet 9 on the piston 12 is greater than the working pressure of the inner elastic member 11, the water pushes the piston 12 to move, and the through hole 5 is opened, at this time, the pressure of the water on the gland 7 is greater than the working pressure of the first spring 6, and the pressure of the water on the piston 12 of the next flower watering device is less than the working pressure of the corresponding inner elastic member 11, so that the water reaches the first cavity 3 through the water inlet 9, and pushes the gland 7 to move, as shown in the first diagram in fig. 2. After the gland 7 moves to the position of the stop block 13, the stop block 13 stops the movement of the gland 7, the water pressure is increased, when the pressure of water on the piston 12 of the next flower watering device is greater than the working pressure of the corresponding inner elastic part 11, the piston 12 of the next flower watering device moves, and the next flower watering device starts to inject water, as shown in the second drawing in fig. 2. When the water supply is stopped, the water pressure of the water inlet 9 disappears, at the moment, the piston 12 blocks the water inlet 9 under the pressure of the spring, the first cavity 3 is communicated with the flower watering hole 10 through the through hole 5, and the water accumulated in the first cavity 3 flows into the flowerpot to water flowers. The water inlet 9 of the next watering device is communicated with the watering hole 10 through the water outlet 8 and the first cavity 3, the water pressure at the water inlet 9 of the next watering device is reduced, the piston 12 of the next watering device acts, and the next watering device realizes watering flowers, as shown in the third picture in fig. 2.
The gland and the piston in the device can move linearly or along a specific curve.
The flower watering device can be independent of the flowerpot, and can also be made into a flowerpot pattern to directly seed flowers.

The third elastic element 48 and the fourth elastic element 49 are both springs, and the third elastic element 48 is sleeved outside the fourth elastic element 49; the inner elastic member 11 has a pressure against water greater than that of the gland 7 by the outer piston 44. The carrier rod 45 is fixedly mounted with a stopper 411, and the fourth elastic member 49 and the inner piston 47 are between the outer piston 44 and the stopper 411.
Specifically, when the pressure of the water in the water inlet 9 on the piston 12 is greater than the sum of the working pressures of the third elastic element 48, the fourth elastic element 49 and the inner elastic element 11, the water pressure presses the outer piston 44 backward, the outer piston 44 pushes the fourth elastic element 49, and the fourth elastic element 49 pushes the inner piston 47 to move backward together until the inner piston 47 contacts the end surface of the third cavity 41, as shown in the second diagram in fig. 7, at which time the spark hole 10 is disconnected from the first cavity 3; the water pressure continues to push back the outer piston 44, and the outer piston 44 presses the inner piston 47 through the fourth elastic member 49 until the push rod 45 contacts the piston 12, as shown in the third drawing of fig. 7; the water pressure continues to push the outer piston 44 backward, the outer piston 44 continues to press the inner piston 47 through the fourth elastic member 49, the push rod 45 pushes the piston 12 backward, and the water flows into the first chamber 3 through the third chamber 41, the second communicating pipe 410, the fourth chamber 42, the first communicating pipe 43 and the through hole 5 from the water inlet 9, as shown in the fourth diagram of fig. 7. When the water pressure at the water inlet 9 disappears, the piston 12 retracts under the combined action of the third elastic member 48, the fourth elastic member 49 and the inner elastic member 11 until the mandril 45 leaves the piston 12, as shown in the second graph in fig. 8, and at this time, the water inlet 9 is disconnected from the first cavity 3; the piston 12 continues to retract under the combined action of the third elastic member 48 and the fourth elastic member 49 until the catch ring 411 contacts the inner piston 47, as shown in the third drawing in fig. 8; the piston 12 continues to retract under the action of the third elastic element 48, the inner piston 47 leaves the end face of the third cavity 41 under the action of the retaining ring 411, and water flows out from the first cavity 3 through the through hole 5, the first communication pipe 43, the third cavity 41 and the flower watering hole 10, as shown in the fourth drawing of fig. 8.
Example 4

Until the pressing covers 7 in the first cavities 3 of all the watering devices of the system reach set positions, the water pressure continues to rise to reach the set pressure of the pressure controller, the water source is controlled to stop supplying water, the water pressure of the water inlet holes 9 of the series-connected initial watering devices disappears, the pistons act, the first cavities 3 are communicated with the watering holes to realize watering, the water inlet holes 9 of the next watering devices are communicated with the watering holes 10 through the first cavities 3, the water pressure of the water inlet holes 9 of the next watering devices is reduced, the pistons of the next watering devices act, and the first cavities 3 of the next watering devices are communicated with the watering holes 10 of the next watering devices to realize watering.
