Description

Technology sector The present utility model application relates to the technical field of flower watering machines, in particular an automatic solenoid valve flower watering machine. Technical background With the acceleration of urbanization and the improvement in living standards, growing potted plants indoors and outdoors has become a popular leisure activity and a form of home decoration. However, busy plant lovers who are frequently away on business trips or have little gardening experience face the challenge of watering plants scientifically and at the right time. Too much water easily leads to oxygen deprivation and root rot, while too little water causes plants to wilt due to dryness—both significantly impair healthy plant growth and can even lead to death. Currently, several simple automatic watering devices for flowers are available on the market, which can be broadly categorized as follows: First, simple drip irrigation systems that utilize capillary action or gravity seepage. With these, the amount of water dispensed is difficult to control precisely, and they cannot adapt to the actual soil moisture; the effect is unstable. Second, electronic irrigation systems with a timer that only water at preset intervals and cannot react in real time to dynamic changes in soil moisture. In prolonged rain or hot, dry weather, they tend to over- or under-water, their level of intelligence is low, and their water usage efficiency is inefficient. Furthermore, most existing devices are structurally complex, difficult to install, or lack an intuitive human-machine interface, making it difficult for the user to perceive the ground status and the operating state of the device in real time – resulting in an unsatisfactory user experience. To solve the aforementioned technical problems, an automatic solenoid valve flower irrigation machine is being developed. Content of the utility model The technical problem that the present utility model application intends to solve is to overcome the disadvantages of the techniques described above and to provide an automatic solenoid valve flower irrigation machine. To solve this technical problem, the present application proposes an automatic solenoid valve flower watering machine with the following technical solution: It comprises a housing, a control board, a solenoid valve, a water inlet connection, and a water outlet connection. Inside the housing, a partition divides the housing into a front chamber and a rear chamber. The control board is located in the front chamber and is attached to the partition by screws. A push-button mechanism is soldered onto the control board, which is also equipped with a display. The solenoid valve is located in the rear chamber. The water inlet connection and the water outlet connection are also located in the rear chamber, on either side of the solenoid valve.The connections on both sides of the solenoid valve are each connected to the water inlet connection and the water outlet connection. A water inlet pipe connection extending from the housing is provided at the lower end of the water inlet connection. At the lower end of the water outlet connection, a water outlet pipe connection extending from the housing is provided. As an improvement, the machine also includes a soil moisture and temperature measuring device that works with the control board and provides it with the measured soil moisture and temperature data. As an improvement, a battery compartment is provided on the back of the housing, with the battery compartment being soldered to the control board via a wire.

Display slot; Specific details The automatic solenoid valve flower irrigation machine according to the invention is described in detail below with reference to the attached drawings. Referring to Figures 1, 2, 3, 4 to 5, an automatic solenoid valve flower watering machine comprises a housing 1, a control board 2, a solenoid valve 3, a water inlet 4, and a water outlet 5. The individual components work together to perform functions such as automatic watering, parameter setting, and data display. The overall structure is compact, and the arrangement is logical, which facilitates assembly and use. The housing 1 serves as a mounting platform for the entire device and is made of a water- and corrosion-resistant plastic. It protects the internal components from environmental influences, while simultaneously reducing the overall weight of the device and thus facilitating setup and movement. Inside the housing 1, a partition 6 is provided, which divides the housing 1 into a front chamber 7 and a rear chamber 8. The front chamber 7 houses the control components, while the rear chamber 8 houses the water-carrying components. This separate arrangement effectively prevents leaks from the water-carrying parts from damaging the control components, thus increasing the stability and service life of the device. The control board 2 is the control center of the device. It is designed as a minimal microcontroller system and has functions for data reception, logic decision-making, and command output. The control board 2 is located in the front chamber 7 and is securely fastened to the partition 6 by screws. This mounting method facilitates the disassembly, maintenance, and replacement of the control board 2. A key mechanism 9 is soldered onto the control board 2, which serves to record user inputs - for example, for manually setting soil moisture thresholds, irrigation durations, calibrating the time or manually opening / closing the valve. The control board 2 is equipped with a display 10 that shows in real time the soil moisture and temperature data recorded by the soil moisture and temperature measuring device 13, the set parameters, the operating status of the solenoid valve and the battery capacity, so that the user can easily see and operate everything. To achieve a good human-machine interface, a key slot 15 extending into the front chamber 7 is provided on the front of the housing 1. The keycaps of the key mechanism 9 protrude from this key slot 15, allowing the user to operate them comfortably. Simultaneously, a display slot 16 extending into the front chamber 7 is provided on the front of the housing 1, its dimensions being matched to the display 10. The display 10 sits precisely in this display slot 16, with its display area flush with or slightly recessed into the housing surface to ensure protection, an aesthetically pleasing appearance, and ease of reading for the user. The solenoid valve 3 is located in the rear chamber 8 and is designed as a normally closed valve. A low-energy, waterproof solenoid valve is selected as the control component for the water shut-off. The control end of the solenoid valve 3 is soldered to the control board 2 via a wire and receives control commands from the control board 2 to open and close the valve. The water inlet port 4 and the water outlet port 5 are also located in the rear chamber 8 and are situated on either side of the solenoid valve 3. The ports on both sides of the solenoid valve 3 are each tightly connected to the water inlet port 4 and the water outlet port 5, respectively. At the lower end of the water inlet connection 4, a water inlet pipe connection 11 extending from the housing 1 is provided, which enables a connection via a hose line to a domestic water tap and thus provides a stable water source for the device. At the lower end of the water outlet connection 5, a water outlet pipe connection 12 extending from the housing 1 is provided, which facilitates the installation of a water line. The other end of the line can be laid up to the soil surface of the flowerpot or into the soil to achieve precise watering. The irrigation machine also includes a separate soil moisture and temperature sensor 13. The sensor 13 is electrically connected to the control board 2 via a wired or wireless connection to enable bidirectional data exchange. It acquires the soil moisture and temperature data of the potting soil in real time and transmits this data to the control board 2, which uses it as a basis for its control decisions. The control board 2 includes a Bluetooth module that can serve as the basis for wireless connection with the soil moisture and temperature measuring device 13. A battery compartment 14 is provided on the rear of the housing 1 for power supply. Dry cell batteries or rechargeable batteries can be inserted into the battery compartment 14. The battery compartment 14 is soldered to the control board 2 via a wire. A key slot 15 extending into the front chamber 7 is provided on the front of the housing 1. The key mechanism 9 protrudes from the key slot 15, allowing the user to operate the key mechanism 9 conveniently. A display slot 16 extending into the front chamber 7 is provided on the front of the housing 1. The display 10 is arranged in the display slot 16. The upper end of the solenoid valve 3 extends out of the housing 1 and forms an area for heat dissipation or manual actuation. This promotes heat dissipation during prolonged operation of the solenoid valve and allows for manual switching in an emergency. In the specific embodiment of the present invention: 1. Assembly of the device: The user connects the water inlet pipe connection 11 to a tap or a higher-level water tank via a hose. The water outlet pipe connection 12 is also connected with a hose, the other end of which is placed at a suitable location in the flowerpot. The probe of the soil moisture and temperature measuring device 13 is inserted into the potting soil, preferably at a depth close to the plant's root zone. Batteries are inserted into the battery compartment 14, and the control board 2 is powered on and started. 2. Parameter setting: The user sets a lower setpoint for soil moisture (e.g., watering to begin below 30% moisture) and an upper setpoint (e.g., watering to stop at 70% moisture) or, alternatively, a watering duration using the button mechanism 9.The set parameters, as well as the current soil moisture and temperature values, are displayed in real time on display 10 so that the user can check them. 3. Automatic irrigation: In standby mode, the soil moisture and temperature sensor 13 continuously or periodically records the soil moisture and temperature data and transmits it to the control board 2. The microprocessor on the control board 2 compares the received actual moisture values ​​with the threshold values ​​set by the user and evaluates them. When the control board 2 detects that the actual soil moisture has fallen below the set lower threshold (i.e., water shortage in the soil), it outputs a control signal that energizes the coil of the solenoid valve 3, thereby actuating the valve core of the solenoid valve 3 and opening the valve passage. The water now flows from the external source sequentially through the water inlet pipe connection 11, the water inlet port 4, the solenoid valve 3, the water outlet port 5, and the water outlet pipe connection 12, finally reaching the potting soil via the connecting pipe – the automatic watering begins. During the irrigation process, the soil moisture and temperature sensor 13 continuously monitors the soil moisture in real time. The control board 2 constantly compares the current moisture level with the set upper threshold. As soon as the soil moisture reaches or exceeds the upper threshold (i.e., the soil is sufficiently watered), the control board 2 immediately sends a shutdown signal, which de-energizes the solenoid valve 3, closes the valve, and interrupts the water flow—the irrigation process stops automatically. In this way, automatic control of the soil moisture is achieved, preventing over- or under-watering. This closed system allows the automatic solenoid valve flower watering machine to always keep the soil moisture in the optimal range for plant growth and completely avoids problems caused by drought or waterlogging resulting from forgotten watering or watering by feel. 4. Data Display and Manual Operation: The user can access real-time soil moisture and temperature data, set threshold values, and the operating status of the device (irrigation or standby) via display 10. The user can manually force-open or close the solenoid valve 3 at any time using the key mechanism 9, for example, to perform a short-term watering or system maintenance. In addition to the real-time data, display 10 also shows the battery capacity, allowing the user to monitor the battery charge level. In summary, the automatic solenoid valve flower watering machine described here offers a compact design. Electrical safety is enhanced by separating the water-carrying area from the control and operating area with a partition. The integration of a soil moisture and temperature sensor, along with an intelligent control board, enables demand-based automatic watering, significantly improving water usage efficiency and ease of maintenance. The user-friendly interface with buttons and a display makes operation intuitive and provides constant visibility of the system's status, greatly improving the user experience.
