[0022] Example 1
[0023] See Figures 1-2 This embodiment provides a fountain water flow control device, including a water pump 2. The water pump 2 is connected to a liquid level sensor 9 for monitoring water level via a second connecting line 4. A second waterproof connector 6 is connected to the second connecting line 4. The water pump 2 is connected to a control box 7 via a first connecting line 3. A first waterproof connector 5 is provided on the first connecting line 3. The control box 7 is connected to a transformer plug 8 via a third connecting line 15. The control box 7 is provided with a control circuit board 10, a clock module 11, and a remote control receiver module 12. The remote control receiver module 12 is wirelessly connected to a remote control 1.
[0024] The first connecting line 3 needs to transmit both the water pump power supply signal and the liquid level sensor signal. It uses a four-core waterproof cable, with two cores for transmitting the water pump power, one core for the liquid level sensor signal transmission, and one core for the common ground. The second connecting line is a two-core wire, with one core connected to the liquid level sensor signal and one core for grounding. That is, the liquid level sensor signal line of the second connecting line is connected to the liquid level sensor signal line of the first connecting line, and the grounding wire of the second connecting line is connected to the grounding wire of the first connecting line.
[0025] The control box 7 includes a control box body 70, which is injection molded from flame-retardant ABS plastic. The control box body 70 is divided into upper and lower layers by a partition 71. The upper layer has a first accommodating cavity 73 and a second accommodating cavity 74, and the lower layer has a third accommodating cavity 75. The cover plate of the control box body 70 is fixed to the control box body with screws, and a silicone waterproof strip is provided at the contact position between the cover plate and the control box body. The control circuit board 10 is disposed in the third accommodating cavity 75, the clock module 11 is disposed in the first accommodating cavity 73, and the remote control receiving module 12 is disposed in the second accommodating cavity 74. Preferably, a metal sheet 72 is disposed within the partition 71. The metal sheet 72 is made of galvanized steel or aluminum plate and is used to block electromagnetic radiation between the lower control circuit board 10 and the upper clock module 11 and remote control receiving module 12, preventing high-frequency noise from interfering with the time accuracy of the clock module and the signal sensitivity of the remote control receiving module. In implementation, the metal sheet is grounded to further enhance the shielding effect.
[0026] The clock module 11 and the remote control receiver module 12 are electrically connected to the control circuit board 10. The control circuit board 10 includes a control chip, a water pump drive module for receiving signals from the control chip to regulate the water pump voltage, and a relay for cutting off the main power supply to the water pump. The relay is installed on the power supply line of the water pump, and its opening and closing can be controlled by the control chip.
[0027] In practice, the transformer plug is connected to the mains power supply to power the control box. Pressing the remote control activates the remote control receiver module, which receives the signal and transmits it to the control chip. The control chip then outputs a PWM signal to the water pump drive module. Based on the received PWM signal, the water pump drive module outputs a corresponding water pump voltage to change the water pump speed; the higher the voltage, the faster the speed and the greater the water flow. The detection signal from the level sensor 9 is transmitted to the control chip on the control circuit board to achieve real-time monitoring of water shortage. When there is water, the level sensor outputs a low-level signal; when there is a water shortage, the level sensor outputs a high-level signal. When the control chip detects this high-level signal, it cuts off the power supply to the water pump via a relay.
[0028] The remote control has ON, OFF, 2H, 4H, 6H, 8H, 10H, 12H, +, and - buttons. Pressing the ON button activates the relay, starting the water pump and operating it at the current water flow level. Pressing the + and - buttons activates the control chip, which can adjust the PWM signal to change the pump speed and water flow. The 2H, 4H, 6H, 8H, 10H, and 12H buttons on the remote control are timer shutdown buttons, corresponding to setting the pump to automatically shut off after 2 hours, 4 hours...12 hours of operation, respectively. When the timer shutdown button is triggered, the control chip records the current time via the clock module 11; after the set duration, it controls the relay to cut off the power to the water pump.
[0029] Example 2
[0030] See Figures 3-4 This embodiment provides a fountain water flow control device, including a water pump 2. The water pump 2 is connected to a liquid level sensor 9 for monitoring water level via a second connecting line 4. A second waterproof connector 6 is connected to the second connecting line 4. The water pump 2 is connected to an integrated plug 13 via a fourth connecting line 16. A third waterproof connector 17 is provided on the fourth connecting line 16. The integrated plug 13 contains a second control circuit board 18, a power conversion circuit board 14, and a second remote control receiver module 19. The second remote control receiver module 19 is wirelessly connected to a remote control. The fourth connecting line needs to transmit both the water pump power supply signal and the liquid level sensor signal. It uses a four-core waterproof cable, with two cores for transmitting the water pump power, one core for transmitting the liquid level sensor signal, and one core for ground. The second connecting line is a two-core wire, with one core connected to the liquid level sensor signal and the other core for grounding. That is, the liquid level sensor signal line of the second connecting line is connected to the liquid level sensor signal line of the fourth connecting line, and the grounding wire of the second connecting line is connected to the grounding wire of the fourth connecting line.
[0031] The integrated plug 13 includes a first circuit cavity 130, a second circuit cavity 131, and a third circuit cavity 132 arranged from right to left. A power conversion circuit board 14 is disposed in the first circuit cavity 130, a control circuit board 18 is disposed in the second circuit cavity 131, and a remote control receiver module 19 is disposed in the third circuit cavity 132. The power conversion circuit board 14 and the control circuit board 18 are electrically connected, and the remote control receiver module 19 is also electrically connected to the control circuit board 18. The pins 15 of the integrated plug 13 are connected to the input terminal of the power conversion circuit board 14. Preferably, metal sheets, made of copper, are disposed within the partition walls between the first and second circuit cavities 130 and 131, and between the second and third circuit cavities 131 and 132, to shield against signal interference. Preferably, the metal sheets are connected to a common ground terminal. Specifically, a small portion of the metal sheet extends out of the outer shell and is connected to the common ground terminal via a grounding wire. The outer shell of the integrated plug is made of high-temperature resistant PC plastic, and the gap between the pins 15 and the outer shell is filled with high-temperature resistant silicone.
[0032] The second control circuit board 18 includes a control chip, a water pump drive module for receiving signals from the control chip to regulate the water pump voltage, and a relay for cutting off the main power supply to the water pump. The relay is located on the power supply line of the water pump, and its opening and closing can be controlled by the control chip. The second control circuit board 18 has a built-in clock module. The power conversion circuit board is an AC-DC switching power supply module, which takes in 220V AC mains power and outputs two DC voltages: one is 12V, which supplies power to the water pump drive module and the relay; the other is 5V, which supplies power to the control chip, the built-in clock module, and the second remote control receiver module of the second control circuit board.
[0033] In practice, the integrated plug is inserted into a mains power socket to connect to the mains power. Pressing the remote control activates the remote control receiver module two, which receives the signal and transmits it to the control chip. The control chip then outputs a PWM signal to the water pump drive module. Based on the received PWM signal, the water pump drive module outputs a corresponding water pump voltage to change the water pump speed; the higher the voltage, the faster the speed and the greater the water flow. The detection signal from the level sensor 9 is transmitted to the control chip on the control circuit board two, enabling real-time monitoring of water shortage. When there is water, the level sensor outputs a low-level signal; when there is a water shortage, the level sensor outputs a high-level signal. When the control chip detects this high-level signal, it cuts off the power supply to the water pump via a relay.
[0034] The remote control has ON, OFF, 2H, 4H, 6H, 8H, 10H, 12H, +, and - buttons. Pressing the ON button activates the relay, starting the water pump and operating it at the current water flow level. Pressing the + or - button sends a signal to the control chip, which can adjust the PWM signal to change the pump speed and thus the water flow. The 2H, 4H, 6H, 8H, 10H, and 12H buttons on remote control 1 are timer shutdown buttons, corresponding to setting the pump to automatically shut off after 2 hours, 4 hours...12 hours of operation, respectively. When the timer shutdown button is triggered, the control chip records the current time via clock module 11; after the set duration, it controls the relay to cut off the power to the water pump.
