[0002] A salt chlorinator, also known as a salt chlorine generator or electrolytic brine chlorination system, is a process device that produces hypochlorite by electrolyzing water containing salt (usually table salt, i.e., sodium chloride NaCl). It is primarily used for swimming pool water treatment, drinking water disinfection, and other applications requiring chlorine disinfection.

[0003] However, in actual use, salt chlorine machines may experience sudden power outages due to various reasons (such as power grid failures, sudden power outages, etc.), which not only interrupts the electrolysis process and affects the disinfection effect, but may also cause abnormal pressure or temperature inside the device, increasing the risk of equipment damage.

[0026] To solve the problems in the background technology, such as Figures 1 to 6As shown, the present invention provides a safe, reliable, and non-stop salt chlorinator circuit, comprising an electrolysis circuit, a main control module 4, and a power supply circuit. The electrolysis circuit is the core circuit of the salt chlorinator, responsible for salt chlorine decomposition, monitoring, and display. The main control module 4, primarily a microprocessor (MCU), monitors and controls the operating status of the entire system, ensuring safe and reliable operation. The power supply circuit is responsible for supplying power to the entire salt chlorinator, wherein the power supply circuit includes a mains power supply module 1, a battery power supply module 2 and a control switch module 3. The mains power supply module 1 is electrically connected to the electrolysis working circuit and the main control module 4, and is used to connect to the power grid to provide a main power supply; the battery power supply module 2 is electrically connected to the electrolysis working circuit and the main control module 4, and is used to provide a backup power supply when the mains power is interrupted; the control switch module 3 is electrically connected to the mains power supply module 1 and the battery power supply module 2, and is used to supply power to the mains power supply module 1 when the mains power is present, and switch to the battery power supply module 2 for power supply when the mains power is cut off; and the main control module 4 includes a detection unit 41, which is electrically connected to the mains power supply module 1, the battery power supply module 2 and the control switch module 3, and is used to detect whether the mains power is interrupted and output a control instruction to the control switch module 3.

[0027] It can be understood that the power supply circuit of this embodiment includes a mains power supply module 1, a battery power supply module 2, and a control switch circuit, all of which are electrically connected to the main control module 4. When the mains power supply module 1 is in normal operation, the main control module 4 also contains a detection unit 41. If it is detected that the mains power supply is normal, the control switch circuit maintains its original state, that is, the mains power supply module 1 continues to supply power. Once a mains power interruption is detected, the detection unit 41 will send a control instruction to the control switch circuit. When the control switch circuit receives the instruction, it will switch from the mains power supply mode to the battery power supply mode. At this time, the battery power supply module 2 begins to supply power to the electrolysis working circuit and the main control module 4. When the mains power is restored, the detection unit 41 again detects that the power supply is normal. At this time, after receiving the instruction to restore power, the control switch circuit will switch back to the mains power supply mode. This ensures the continuity of the salt chlorinator's operation and thus guarantees the disinfection effect. At the same time, by switching to the backup power supply in a timely manner, internal pressure or temperature abnormalities caused by sudden power interruptions are avoided, thereby reducing the possibility of equipment damage.

[0028] like Figure 3 as well as Figure 4 As shown, in this embodiment, the battery power module 2 includes a battery unit 21 electrically connected to the main control module 4 for providing DC power, and a boost unit 22 electrically connected to the battery unit 21 for boosting the DC power provided by the battery unit 21. The battery unit 21 includes a battery pack and a control circuit. When the detection unit 41 detects a low level, the 1-way control Q11 causes K10 to operate in the pull-in state, causing the battery power module 2 to output a 5V voltage. And as Figure 4 As shown, the output 5V voltage is boosted by the boost unit 22 to the voltage suitable for the electrolysis working circuit.

[0029] like Figure 4 As shown, the battery-powered module 2 of this embodiment also includes an inverter unit 23. The input of this inverter unit 23 is connected to the output of the boost unit 22, and is used to convert the boosted DC power into AC power. After the battery voltage is boosted, it is converted through a full-bridge inverter consisting of transistors Q7, Q8, Q9, and Q10. These transistors alternately turn on and off, converting the DC voltage into AC power suitable for the electrolysis circuit.

[0030] like Figure 2 As shown, the AC power supply module 1 of this embodiment includes a transformer unit 11 for adjusting the AC voltage to a suitable level, and a rectifier unit 12 electrically connected to the transformer unit 11 for converting AC power into pulsating DC power. After receiving the AC power, the transformer unit 11, which is a transformer, adjusts the AC voltage. The rectifier unit 12, which is composed of a bridge rectifier consisting of four diodes, is used to convert the transformed AC power into unidirectional pulsating DC power for use by the MCU main control chip.

[0031] like Figure 2 As shown, in this embodiment, the mains power supply module 1 further includes a step-down unit 13. The input end of the step-down unit 13 is connected to the output end of the rectifier unit 12, and the DC-DC step-down chip U6 is used to reduce the rectified DC voltage to a level suitable for the operation of the MCU main control module 4.

[0032] U5 is the MCU chip, and its fifth pin is connected to the output of the AC power supply module 1. When the AC power is functioning properly, the AC power SD-DC is split into three paths. One path is divided by R32 and R33 and reaches U5's fifth pin. This detects the AC power is normal. The second path controls Q4, which in turn controls Q2, causing K9 to operate normally (relay K9 does not operate). The third path controls Q12, which in turn controls Q11, causing K10 to operate normally (relay K10 does not operate). At this point, the AC power is supplied. When the AC power is absent, U5's fifth pin detects a low level, and U5's first pin outputs two paths: path 1 controls Q11, causing K10 to operate in the energized state; path 2 controls Q2, causing K9 to operate in the energized state. At this point, the battery power supply module 2 is supplied.

[0033] The embodiments described above are only preferred implementation methods of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and modifications made by technicians in this field on the basis of the utility model shall fall within the scope of protection of the present invention.
