[0038] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate for the embodiments of this application described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0039] In addition, the term "multiple" should mean two or more.

[0040] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0041] In one embodiment, such as Figure 1As shown, a disinfection control circuit is provided, including a signal conditioning circuit 10, a signal detection circuit 20, and a processing module 30. The signal conditioning circuit 10 is connected to a disinfection module 60; the signal detection circuit 20 is connected to the signal conditioning circuit 10; the processing module 30 is connected to the disinfection module 60, the signal conditioning circuit 10, and the signal detection circuit 20 respectively. The processing module 30 is used to control the disinfection module 60 to start working based on a preset current value according to the user's disinfection command, so that the signal detection circuit 20 detects the actual current value of the disinfection module 60; the processing module 30 is also used to acquire the actual current value, and control the signal conditioning circuit 10 to adjust the power supply voltage of the disinfection module 60 according to the actual current value and the preset current value, and to supply power to the disinfection module 60 according to the adjusted power supply voltage.

[0042] The disinfection module 60 can be applied to disinfection and water purification equipment. It outputs disinfected water, and by controlling the disinfection process of the module, the concentration of the output disinfected water can be controlled. For example, the disinfection module 60 can be an ozone disinfection module 60, which generates ozone and utilizes its strong oxygen properties to disinfect the substances to be disinfected.

[0043] The signal detection circuit 20 is used to detect the actual current value of the disinfection module 60. The signal detection circuit 20 is connected to the processing module 30, and thus the signal detection circuit 20 can transmit the detected actual current value to the processing module 30. The signal adjustment circuit 10 is used to adjust the power supply voltage of the disinfection module 60. The signal adjustment circuit 10 is connected to the processing module 30, and thus the processing module 30 can transmit an adjustment signal to the signal adjustment circuit 10 according to the actual current value and a preset current value, so that the signal adjustment circuit 10 adjusts the power supply voltage of the disinfection module 60 according to the adjustment signal.

[0044] The processing module 30 includes an MCU (microcontroller unit) and peripheral circuits connected to the MCU. The processing module 30 may also include a memory, which is used to store data such as preset current values ​​and power supply voltage.

[0045] For example, the processing module 30 is connected to the disinfection module 60, the signal conditioning circuit 10, and the signal detection circuit 20. When a user clicks on the disinfection mode on the operation panel of the disinfection and water purification equipment, the operation panel sends a corresponding user disinfection command to the processing module 30. The processing module 30 receives the user disinfection command, obtains a preset current value, and controls the disinfection module 60 to start working based on the preset current value, so that the disinfection module 60 outputs disinfected water of the corresponding concentration. Simultaneously, the processing module 30 controls the signal detection circuit 20 to detect the actual current value of the disinfection module 60 and transmits the detected actual current value to the processing module 30. The processing module 30 processes the actual current value and the preset current value, and based on the processing result, transmits a corresponding adjustment signal to the signal conditioning circuit 10. The signal conditioning circuit 10 adjusts the power supply voltage of the disinfection module 60 according to the adjustment signal and transmits the adjusted power supply voltage to the disinfection module, allowing the disinfection module 60 to operate according to the adjusted power supply voltage, thus achieving adaptive adjustment of the disinfection concentration of the disinfection module 60. It should be noted that the adjustment signal can be a PWM (Pulse Width Modulation) voltage regulation signal. The preset current value is the initial current value preset by the system.

[0046] In the above embodiments, a signal conditioning circuit 10 is connected to a disinfection module 60; a signal detection circuit 20 is connected to the signal conditioning circuit 10; and a processing module 30 is connected to the disinfection module 60, the signal conditioning circuit 10, and the signal detection circuit 20. The processing module 30, based on a user's disinfection command and a preset current value, controls the disinfection module 60 to start operation, allowing the signal detection circuit 20 to detect the actual current value of the disinfection module 60. The processing module 30 obtains the actual current value and, based on the actual current value and the preset current value, controls the signal conditioning circuit 10 to adjust the power supply voltage of the disinfection module 60. It then supplies power to the disinfection module 60 according to the adjusted power supply voltage, achieving adaptive adjustment of the disinfection module 60. This application uses the signal detection circuit 20 to detect the actual current value of the disinfection module 60 and the signal conditioning circuit 10 to adjust the power supply voltage of the corresponding disinfection module 60, thereby achieving adaptive adjustment of the disinfection concentration of the disinfection module 60 and reducing the error in disinfection concentration control.

[0047] In one embodiment, such as Figure 2As shown, the signal conditioning circuit 10 includes a current conditioning circuit 110 and a voltage conditioning circuit 120; the current conditioning circuit 110 and the voltage conditioning circuit 120 are connected to the disinfection module 60, and the voltage conditioning circuit 120 is connected to the processing module 30; the current conditioning circuit 110 is used to adjust a preset current value; the processing module 30 is also used to transmit a voltage regulation signal to the voltage conditioning circuit 120 when the actual current value and the preset current value meet the preset voltage regulation conditions, so that the voltage conditioning circuit 120 adjusts the power supply voltage of the disinfection module 60 according to the voltage regulation signal.

[0048] The current adjustment circuit 110 is used to adjust the preset current value of the corresponding disinfection module 60. For example, the current adjustment circuit 110 is equipped with an adjustable current limiting resistor, and different preset current values ​​can be set by adjusting the resistance value of the adjustable current limiting resistor.

[0049] The voltage regulation circuit 120 is used to regulate the power supply voltage of the corresponding disinfection module 60. The voltage regulation circuit 120 is connected to both the disinfection module 60 and the processing module 30. The processing module 30 processes the actual current value and the preset current value transmitted by the signal detection circuit 20. When the actual current value and the preset current value meet the preset voltage regulation conditions, it generates a corresponding voltage regulation signal and transmits the voltage regulation signal to the voltage regulation circuit 120. This allows the voltage regulation circuit 120 to adjust the power supply voltage according to the voltage regulation signal and transmit the adjusted power supply voltage to the disinfection module 60. This adaptively adjusts the power supply to the disinfection module 60, thereby achieving adaptive adjustment of the disinfection concentration output by the disinfection module 60. This avoids using a single predetermined concentration for disinfection and reduces the error in disinfection concentration control. It should be noted that the voltage regulation signal can be a PWM voltage regulation signal.

[0050] In one embodiment, the processing module 30 is further configured to transmit a voltage regulation signal to the voltage regulation circuit 120 when the ratio of the actual current value to the preset current value falls within a preset threshold range.

[0051] The processing module 30 compares the actual current value with the preset current value to obtain the ratio of the actual current value to the preset current value. It then compares this ratio with a preset threshold range. When the ratio falls within the preset threshold range, a corresponding voltage regulation signal is generated and transmitted to the voltage regulation circuit 120. The voltage regulation circuit 120 adjusts the supply voltage according to the voltage regulation signal and transmits the adjusted supply voltage to the disinfection module 60. This adaptively adjusts the power supply to the disinfection module 60, thereby achieving adaptive adjustment of the disinfection concentration output by the disinfection module 60. This avoids using a single predetermined concentration for disinfection and improves the accuracy of disinfection concentration control.

[0052] In one embodiment, the processing module 30 is further configured to supply power to the disinfection module 60 based on the actual current value and the adjusted power supply voltage when the ratio of the actual current value to the preset current value falls within a preset threshold range and the voltage regulation time of the voltage regulation circuit 120 is less than a first time threshold.

[0053] The processing module 30 is also used to time the voltage regulation process of the voltage regulation circuit 120 to obtain the voltage regulation time. When the ratio of the actual current value to the preset current value falls within the preset threshold range, the processing module 30 acquires the voltage regulation time of the voltage regulation circuit 120 in real time and compares the voltage regulation time of the voltage regulation circuit 120 with a first time threshold. When the voltage regulation time of the voltage regulation circuit 120 is less than the first time threshold, the processing module 30 supplies power to the disinfection module 60 based on the actual current value and the adjusted supply voltage to adaptively adjust the power supply of the disinfection module 60, thereby achieving adaptive adjustment of the disinfection concentration output by the disinfection module 60 and further improving the accuracy of disinfection concentration control.

[0054] In one embodiment, the processing module 30 is further configured to supply power to the disinfection module 60 based on the preset current value when the ratio of the actual current value to the preset current value does not fall within the preset threshold range.

[0055] The processing module 30 compares the ratio of the actual current value to the preset current value with the preset threshold range. Based on the comparison result, when the ratio of the actual current value to the preset current value does not fall within the preset threshold range, the processing module 30 supplies power to the disinfection module 60 based on the preset current value, thereby automatically adjusting the disinfection concentration output by the disinfection module 60.

[0056] In one embodiment, such as Figure 3 As shown, the voltage regulation circuit 120 includes a voltage regulation chip 122 and a voltage limiting circuit 124; the voltage limiting circuit 124 is connected to the voltage regulation chip 122 and the disinfection module 60 respectively; the voltage limiting circuit 124 is used to connect to the voltage regulation chip 122 when the regulated supply voltage is greater than the preset maximum threshold, and disconnect from the voltage regulation chip 122 when the regulated supply voltage is less than or equal to the preset maximum threshold.

[0057] The voltage limiting circuit 124 limits the output voltage of the voltage regulating chip 122. For example, the preset maximum threshold is 15V. The voltage regulating chip 122 has a CS pin. When the regulated supply voltage is less than or equal to 15V, the connection to the CS pin of the voltage regulating chip 122 is disconnected; when the regulated supply voltage is greater than 15V, the connection to the CS pin of the voltage regulating chip 122 is connected, causing the voltage at the CS pin of the voltage regulating chip 122 to rise, thereby reducing the regulated supply voltage. This achieves adaptive adjustment of the supply voltage of the disinfection module 60, thus adaptively adjusting the disinfection concentration output by the disinfection module 60 and improving the accuracy of disinfection concentration control. For example, the voltage limiting circuit 124 is equipped with a comparator, the output of which is connected to the voltage regulating chip 122. By comparing the supply voltage with a preset standard voltage in real time, the magnitude of the supply voltage is modulated and adjusted according to the comparison result.

[0058] In one embodiment, such as Figure 4 As shown, the disinfection control circuit also includes a power conversion circuit 40, which is used to connect to the power supply; the signal conditioning circuit 10 also includes a low-power processing circuit 130, which is connected to the processing module 30, the power conversion circuit 40 and the voltage regulation chip 122 respectively; the low-power processing circuit 130 is used to control the on / off of the power supply circuit between the power conversion circuit 40 and the voltage regulation chip 122 according to the drive signal of the processing module 30.

[0059] The power conversion circuit 40 converts the electrical signal transmitted by the power supply into an electrical signal that meets the power supply requirements of the voltage regulator chip 122. The low-power processing circuit 130 controls the switching between the power conversion circuit 40 and the voltage regulator chip 122 to reduce power consumption.

[0060] For example, the low-power processing circuit 130 is equipped with a switching transistor. The processing module 30 is connected to the low-power processing circuit 130. The processing module 30 can control the switching transistor in the low-power processing circuit 130 to control the power supply circuit between the power conversion circuit 40 and the voltage regulation chip 122, thereby saving power and realizing low-power disinfection control.

[0061] In one embodiment, such as Figure 4 As shown, the disinfection control circuit also includes a flow detection circuit 50; the flow detection circuit 50 is connected to the processing module 30; the flow detection circuit 50 is used to detect the outflow value of the disinfection module 60; the processing module 30 is also used to acquire the outflow value detected by the flow detection circuit 50, and when the outflow value is greater than the preset flow threshold and the outflow duration is greater than the second time threshold, the control signal detection circuit 20 detects the actual current value of the disinfection module 60.

[0062] The flow detection circuit 50 can be used to detect the outflow rate of the disinfection module 60. The preset flow threshold can be obtained according to the system preset, for example, the preset flow threshold can be set to 0.3L / min.

[0063] Based on the connection between the processing module 30 and the flow detection circuit 50, the processing module 30 compares the received effluent flow rate value with a preset flow rate threshold. When the effluent flow rate value is greater than the preset flow rate threshold, the effluent from the disinfection module 60 is adjusted in time to obtain the effluent duration. This duration is then compared with a second time threshold. When the effluent duration is greater than the second time threshold, the control signal detection circuit 20 is activated to detect the actual current value of the disinfection module 60. Furthermore, the processing module 30 acquires the actual current value and, based on the actual current value and the preset current value, controls the signal adjustment circuit 10 to adjust the power supply voltage. The adjusted power supply voltage is then used to power the disinfection module 60, achieving adaptive adjustment of the disinfection module 60 and thus reducing the error in disinfection concentration control.

[0064] In one embodiment, such as Figure 5 As shown, a disinfection control method is also provided, including the following steps:

[0065] Step S510: According to the user's disinfection instruction, the disinfection module is started based on the preset current value so that the signal detection circuit can detect the actual current value of the disinfection module.

[0066] For example, when a user clicks on the disinfection mode on the control panel of the disinfection and water purification equipment, the control panel sends a corresponding user disinfection command to the processing module. The processing module obtains a preset current value based on the received user disinfection command and controls the disinfection module to start working based on the preset current value, so that the disinfection module outputs disinfected water of the corresponding concentration. At the same time, the processing module controls the signal detection circuit to detect the actual current value of the disinfection module.

[0067] Step S520: Obtain the actual current value, and adjust the power supply voltage of the disinfection module according to the actual current value and the preset current value, and supply power to the disinfection module according to the adjusted power supply voltage.

[0068] The processing module processes the actual current value and the preset current value, and transmits the corresponding adjustment signal to the signal conditioning circuit according to the processing result. The signal conditioning circuit adjusts the power supply voltage of the disinfection module according to the adjustment signal, and transmits the adjusted power supply voltage to the disinfection module, so that the disinfection module works according to the adjusted power supply voltage, thereby realizing adaptive adjustment of the disinfection concentration of the disinfection module.

[0069] In the above embodiments, the processing module controls the disinfection module to start working based on a preset current value according to the user's disinfection command, so that the signal detection circuit detects the actual current value of the disinfection module. The processing module obtains the actual current value and, based on the actual current value and the preset current value, controls the signal adjustment circuit to adjust the power supply voltage of the disinfection module, and supplies power to the disinfection module according to the adjusted power supply voltage, thereby achieving adaptive adjustment of the disinfection module. This application detects the actual current value of the disinfection module through a signal detection circuit and adjusts the power supply voltage of the corresponding disinfection module through a signal adjustment circuit, thereby adjusting the power supply voltage of the disinfection module to achieve adaptive adjustment of the disinfection concentration of the disinfection module and reducing the error in disinfection concentration control.

[0072] The current detection unit is used to control the disinfection module to start working based on a preset current value according to the user's disinfection command, so that the signal detection circuit can detect the actual current value of the disinfection module.

[0073] The voltage regulation unit is used to obtain the actual current value, and according to the actual current value and the preset current value, control the signal regulation circuit to adjust the power supply voltage of the disinfection module, and supply power to the disinfection module according to the adjusted power supply voltage.
