Detailed Implementation

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] like Figures 1 to 9 As shown, the automatic watering device for potted plants includes a water tank 1. A water inlet pipe 2 is fixedly connected to the upper surface of the water tank 1. A sealing plug 3 is threaded onto the inner wall of the water inlet pipe 2. A support plate 4 is fixedly connected to the left side of the water tank 1. A water pump 5 is fixedly connected to the upper surface of the support plate 4. A U-shaped pipe 6 is fixedly connected to both the water inlet end of the water pump 5 and the left side of the water tank 1. A vertical pipe 7 is fixedly connected to the water outlet end of the water pump 5. A solenoid valve 8 is fixedly connected to the top of the vertical pipe 7. A water outlet hose 9 is fixedly connected to the top of the solenoid valve 8. A first arc-shaped pipe 10 is fixedly connected to the left end of the water outlet hose 9. A rubber sleeve 11 is fitted onto the surface of the first arc-shaped pipe 10. A second arc-shaped pipe 12 is fitted to the inner wall of the rubber sleeve 11. Water injection pipes 13 are fixedly connected to the bottom of pipe 12 and the bottom of the first arc-shaped pipe 10. Circular holes 14 are opened on the upper surface of the first arc-shaped pipe 10. A cylinder 15 is fixedly connected to the inner wall of the circular hole 14. A threaded post 16 is fitted to the inner wall of the cylinder 15. Nuts 17 are fitted to the upper and lower sides of the cylinder 15. The inner wall of the nut 17 is threadedly connected to the surface of the threaded post 16. A humidity sensor 18 is fixedly connected to the bottom of the threaded post 16. A control module 19 is fixedly connected to the front of the water tank 1. An installation hole 24 is opened on the upper surface of the water tank 1. A level gauge 25 is fixedly connected to the inner wall of the installation hole 24. The output end of the level gauge 25 is electrically connected to the input end of the microcontroller 193.

[0029] The control module 19 includes a housing 191, a touch screen 192, a microcontroller 193, a WIFI module 194, and a Bluetooth module 195. The back of the housing 191 is fixedly connected to the front of the water tank 1, the front of the housing 191 is fixedly connected to the back of the touch screen 192, and the front of the Bluetooth module 195, the microcontroller 193, and the WIFI module 194 are all fixedly connected to the inner wall of the housing 191.

[0030] The output terminal of the humidity sensor 18 is electrically connected to the input terminal of the microcontroller 193, the input terminal of the water pump 5 is electrically connected to the output terminal of the microcontroller 193, the input terminal of the solenoid valve 8 is electrically connected to the output terminal of the microcontroller 193, the touch display screen 192 is bidirectionally electrically connected to the microcontroller 193, the WIFI module 194 is bidirectionally signal connected to the microcontroller 193, and the Bluetooth module 195 is bidirectionally signal connected to the microcontroller 193.

[0031] It should be noted that water can enter the water tank 1 through the inlet pipe 2. The inlet pipe 2 can be sealed by the sealing plug 3. The first arc-shaped pipe 10 and the second arc-shaped pipe 12 are connected together by the rubber sleeve 11. At the same time, when the water pump 5 and the solenoid valve 8 are opened, the water in the water tank 1 can be discharged through the water injection pipe 13. By adjusting the position of the adjusting nut 17 on the threaded post 16, the distance between the humidity sensor 18 and the cylinder 15 can be changed. By changing the distance between the humidity sensor 18 and the cylinder 15, the position of the humidity sensor 18 in the soil can be adjusted according to the needs of different plants.

[0032] The microcontroller 193 is an Arduino or Raspberry Pi. The status of the automatic plant waterer is displayed on the touchscreen 192. Users can also set parameters via the touchscreen 192. The automatic plant waterer can connect to a mobile phone via the WIFI module 194 and Bluetooth module 195, allowing users to operate it using their phones. The humidity sensor 18 monitors the soil moisture. When the humidity sensor detects a value below a minimum threshold, the microcontroller 193 activates the water pump 5 and solenoid valve 8, causing the water pump 5 to fill the water tank 1. Water is injected into the soil through pipe 13. When the humidity sensor 18 detects a value that is high enough to reach the maximum threshold, the microcontroller 193 shuts off the water pump 5 and the solenoid valve 8, preventing water from the water tank 1 from being injected into the soil through the water injection pipe 13. The liquid level in the water tank 1 can be monitored by the level gauge 25. When the liquid level in the water tank 1 is low enough to reach the minimum threshold, the microcontroller 193 sends a reminder message to the WIFI module 194 and the Bluetooth module 195. Then, the reminder message is sent to the user's mobile phone through the WIFI module 194 and the Bluetooth module 195. At this time, the reminder message reminds the user to add water to the water tank 1 in time.

[0033] like Figures 1 to 6 As shown, hollow blocks 20 are fixedly connected to the left side of the first arc-shaped tube 10 and the right side of the second arc-shaped tube 12. A threaded cylinder 21 is fixedly connected to the inner wall of the hollow block 20. A bolt 22 is threadedly connected to the inner wall of the threaded cylinder 21. A limiting circular plate 23 is fixedly connected to the bottom of the bolt 22. The axis of the limiting circular plate 23 coincides with the axis of the threaded cylinder 21. The diameter of the limiting circular plate 23 is larger than the outer diameter of the threaded cylinder 21.

[0034] It should be noted that by adopting the precise matching design of threaded cylinder 21 and bolt 22, the user can easily adjust the distance between the limiting circular plate 23 and the hollow block 20 by simply rotating bolt 22. At the same time, when the water injection pipe 13 is inserted into the soil, the limiting circular plate 23 can effectively limit the insertion depth of the water injection pipe 13.

[0035] The working principle of this utility model is as follows: First, separate the rubber sleeve 11 from the first arc-shaped tube 10 and the second arc-shaped tube 12. Then, place the first arc-shaped tube 10 and the second arc-shaped tube 12 on the left and right sides of the plant respectively, and put the rubber sleeve 11 on the first arc-shaped tube 10 and the second arc-shaped tube 12 to connect the first arc-shaped tube 10 and the second arc-shaped tube 12. Then, insert the water injection pipe 13 and the humidity sensor 18 into the soil, and limit the insertion depth of the water injection pipe 13 and the humidity sensor 18 by the limiting circular plate 23.

[0036] When the humidity sensor 18 is inserted into the soil, it monitors the soil humidity. When the value detected by the humidity sensor 18 is as low as the minimum threshold, the microcontroller 193 opens the water pump 5 and the solenoid valve 8, and the water pump 5 injects water from the water tank 1 into the soil through the water injection pipe 13. When the value detected by the humidity sensor 18 is as high as the maximum threshold, the microcontroller 193 closes the water pump 5 and the solenoid valve 8, and the water from the water tank 1 is no longer injected into the soil through the water injection pipe 13.

[0037] Meanwhile, when the liquid level in water tank 1 drops to the minimum threshold, microcontroller 193 sends a reminder message to WIFI module 194 and Bluetooth module 195. Then, the reminder message is sent to the user's mobile phone through WIFI module 194 and Bluetooth module 195. At this time, the reminder message reminds the user to add water to water tank 1 in time.

[0038] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
