Description

Technical Field

[0001] The present invention relates to the field of automatic watering of flowers. Background Art

[0002] Potted plants are a common form of domestic plants and exist in almost every household. The watering management of potted plants directly affects their growth. The watering interval and watering amount have a great impact on the growth of potted plants. These problems have always been a difficult problem that flower lovers who cannot go home in time due to business trips and often forget to water their flowers need to solve urgently. Too much or too little watering of potted plants will cause leaves to wither and flowers to wilt, and even plant death, which also troubles many people who love flowers but do not know how to grow them. Therefore, we have made improvements to this and proposed an automatic watering device. Summary of the invention

[0003] The present invention provides an automatic watering device which can automatically water a plurality of potted plants and individually adjust the watering interval and watering amount of each potted plant. The automatic watering device has the advantages of simple structure, convenient use and good watering effect.

[0004] In order to solve the problems existing in the background technology, the present invention adopts the following technical solutions.

[0005] The automatic watering device includes a water pump unit 18, a plurality of water valve units 19, a water pipe 20 and a mobile phone APP.

[0006] The water pump unit 18 is composed of a water pump 6, a water pump driving module 9, and a water pump wireless communication module 8. The water pump wireless communication module 8 is used for communication between the water pump unit 18 and the water valve unit 19 and for sending the start and stop status of the water pump 6 to the water valve unit 19. The water pump driving module 9 is used to start and stop the water pump 6.

[0007] The above-mentioned water valve unit 19 is composed of a water valve battery 10, a valve 14, a water valve communication and driving module 16, and a reduction motor 13. The water valve battery 10 supplies power to the water valve unit communication and driving module 16. The above-mentioned water valve unit wireless communication and driving module 16 are used to adjust and control the watering interval time, watering time and communication between the valve unit 19 and the water pump unit 18.

[0008] The communication module 8 installed inside the above water pump unit 18 adopts WIFI + Bluetooth dual-mode communication. The WIFI communication method can realize remote manual watering and check the watering records of each water valve unit 19 and the power level of the battery 10.

[0009] The opening angle of the water valve 14 in the water valve unit 19 is adjustable. By controlling the opening angle of the valve 14, various watering modes such as drip irrigation, normal watering, and spray watering can be set.

[0010] The invention has a simple structure and is easy to use, and can prevent plants from having an unfavorable growth environment due to lack of water or excessive watering. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0016] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0017] Example: Figure 1-3 As shown, in an automatic watering device of the present invention, the water outlet 4 of the water pump unit 18 is connected to the water inlet 15 of the water valve unit by a water pipe, the water outlet 11 of each water valve unit is connected to the water inlet 15 of the next water valve unit by a water pipe 20, and the water outlet 11 of the last water valve unit is blocked by a plug 21 to seal the waterway. The lower half of each water valve unit 19 is buried in the soil of the potted plant 22 with the watering port 12 facing the inner side of the potted plant, so as to fix the valve unit 19 and allow the water of the water outlet 12 to accurately flow into the potted plant 22.

[0018] The internal structure of the water pump unit 18 is as follows Figure 2: The water storage tank cover 1 can be opened to add water, the bottom of the water storage tank 2 is connected to the water inlet 3 of the water pump. When the water pump rotates, water flows from the water inlet 3 through the water pump 6 to the water outlet 4 of the water pump. The water pump communication module 8 adopts dual-mode communication. The WIFI communication method is used for communication between the water pump unit 18 and the mobile phone APP, and the Bluetooth communication method is used for communication between the water pump unit 18 and the water valve unit 19.

[0019] The internal structure of the water valve unit 19 is as follows Figure 3 :The function is composed of a three-way part and peripheral structure consisting of a water inlet 15, a water outlet 11, a watering port 12 and a valve 14. The water inlet 15 is connected to the water outlet 11. The water valve unit communication and driving module 16 is connected to the battery 10 by a wire 17. The reduction motor 13 is electrically connected to the valve unit communication and driving module 16 to drive the reduction motor. Each water valve unit is set with a physical number. There is also a software number consistent with the physical number in the water valve unit communication software. The user distinguishes each valve unit by the physical number, and the water pump communication module 8 distinguishes each valve unit by the software number.

[0020] The action flow of valve 14: When the water valve unit communication and drive module 16 logically judge that watering is needed, the reduction motor 13 drives the valve 14 to rotate 90° clockwise, and the watering port 12 is connected with the water inlet 15, and the water valve 14 is opened. The water valve unit communication and drive module 16 logically judges that when watering is finished, the reduction motor 13 drives the valve 14 to rotate 90° counterclockwise, and the watering port 12 is not connected with the water inlet 15, and the water valve 14 is closed. The water valve unit communication and drive module 16 obtains the open and closed state of the valve 14 through the micro-stroke switch. After the open and closed state of the water valve 14 changes, the current state is sent to the water pump unit, and after the stop and start state of the water pump 6 changes, the current state is sent to the water valve unit.

[0021] Water valve unit data setting process: For ease of understanding Figure 1 The physical number of the water valve unit 19 is assumed to be M. The data setting process of the water valve unit with the physical number M is explained here. After the mobile phone shows that the water pump unit is connected to the WiFi network, enter the number M of the water valve unit to be set on the mobile phone, and wait for the mobile phone interface to show that the water valve unit M and the water pump unit are connected. The water pump unit relays the watering interval time and watering time data sent by the mobile phone via WIFI and sends it to the water valve unit M via Bluetooth. That is, the data setting of the water valve unit with the physical number M is completed.

[0022] The process of watering is as follows: first fill the water storage tank 2 with water. After the watering interval of the water valve unit 19 ends, the valve 14 of the water valve unit 19 opens. After the valve 14 opens, a signal to start the water pump 6 is sent to the water pump unit 18 and the water valve unit 19 starts the watering timing. The water pump starts 6 and watering begins. After the watering timing reaches the set time, the water valve unit 19 sends a stop signal of the water pump 6 to the water pump unit 18. After the water pump 6 stops, the valve 14 closes and a watering cycle ends. The water valve unit 19 starts the watering interval timing and enters the next watering cycle.
