Fig. 4 schematically shows a flow chart of a power supply control method of an embodiment of the present invention. Referring to fig. 1, the power supply control method provided in the embodiment of the present invention specifically includes steps S11 to S14, as follows:
and S11, acquiring the working current of the ionizer.
In this embodiment, the operating current of the ionizer is obtained to realize current monitoring of the running process of the ionizer. Optimally, real-time working current is obtained to improve monitoring accuracy.
And S12, judging whether the working current meets the preset target current range adjustment condition.
And S13, if the working current meets the preset target current range adjusting condition, adjusting the target current range according to a preset adjusting strategy.
And S14, controlling the ionizer according to the adjusted target current range so as to adjust the output voltage of the ionizer.
Specifically, in order to maintain stable operation, the operating current of the ionizer needs to be maintained within a certain range, so that the target current range of the ionizer is preset, and the voltage generated by the ionizer is controlled according to the preset target current range to provide a corresponding target current. It can be understood that the load change is often accompanied in the use process of the ionizer, even if the ionizer provides voltage according to the target current range, the actual working current will change compared with the ideal target current under the current voltage, therefore, when the actual working current does not meet the working requirement, the target current range should be correspondingly adjusted according to the change condition of the actual working current, so as to provide voltage according to the adjusted target current range, achieve the purpose of adjusting the actual working current, and make the actual working current meet the working requirement.
Based on this, in this embodiment, when the operating current meets a preset target current range adjustment condition, that is, the current operating current does not meet the operating requirement, the target current range is adjusted according to a preset adjustment strategy.
According to the power supply control method provided by the embodiment of the invention, after the working current of the ionizer is obtained, whether the working current meets the preset target current range adjusting condition is judged, when the working current meets the preset target current range adjusting condition, the target current range is adjusted according to a preset adjusting strategy, and finally, the ionizer is controlled according to the adjusted target current range, so that the output voltage of the ionizer is adjusted. The invention can effectively control the output voltage of the ion generator, avoid strong discharge or continuous discharge of the ion generator caused by overlarge power supply, further generate excessive ozone, help users to prevent ozone harm, and improve product performance and user experience.
In an embodiment of the present invention, the step S12 of determining whether the operating current satisfies the preset target current range adjustment condition specifically includes the following steps S121 to S122 that are not shown in the drawings:
s121, judging whether the working current is higher than a preset current threshold value;
and S122, if the working current is higher than the preset current threshold, judging that the working current meets a preset target current range adjustment condition.
Specifically, the ionizer may be subjected to a strong high voltage discharge or a continuous high voltage discharge during its use, in which the instantaneous generation amount of ozone is rapidly increased, and the discharge process is accompanied by an increase in current. Therefore, a preset current threshold value is set, when the working current of the ionizer is higher than the preset current threshold value, the strong discharge of the ionizer is indicated, the current target current range is adjusted according to the overhigh output voltage provided by the current target current range, the output voltage is reduced, the strong discharge and the persistent discharge are eliminated, and the generation of ozone is inhibited.
In an embodiment of the present invention, after the step S13 of determining that the working current satisfies the preset target current range adjustment condition, the method further includes the following steps S131 to S134:
s131, accumulating and counting the times that the working current is higher than the preset current threshold value to obtain a count value;
s132, judging whether the count value is larger than a preset count threshold value;
s133, if the count value is larger than the preset count threshold, reducing the minimum threshold of the target current range by a first preset value, and reducing the maximum threshold of the target current range by a second preset value to obtain an adjusted first target current range;
and S134, controlling the ionizer according to the adjusted first target current range so as to adjust the output voltage of the ionizer.
Specifically, after the currently acquired working current is judged to be higher than the preset current threshold, the counting is accumulated, and each time the currently acquired working current is judged to be higher than the preset current threshold,the count value is incremented by one. Meanwhile, the counting value is compared with a preset counting threshold value, and if the counting value is larger than the preset counting threshold value, the current target current range (I) is indicatedlow，Ihigh) The supplied voltage is too large, strong discharge of the ionizer frequently occurs, and the minimum threshold value I of the current target current range is setlowDecrease the first preset value △ I1A maximum threshold value I of the target current rangehighDecrease the second preset value △ I2Obtaining the adjusted first target current range (I)low-△I1，Ihigh-△I2) Further, the ionizer is controlled to provide a corresponding output voltage in accordance with the adjusted first target current range, more specifically, the first preset value △ I1And said second preset value △ I2The value of (A) can be two preset same or different values, and can also be taken by a control program according to a preset operation logic.
It should be noted that, when the count value is greater than the preset count threshold and the current target current is adjusted, the count value is cleared, and the working current of the ionizer is continuously monitored.
In an embodiment of the present invention, the step S12 of determining whether the operating current meets the preset target current range adjustment condition specifically includes the following steps S121 'to S122', which are not shown in the drawings:
s121', judging whether the working current is higher than a preset protection current threshold value or not;
and S122', if the working current is higher than the preset protection current threshold value, judging that the working current meets a preset target current range adjustment condition.
Specifically, when the ionizer generates an intense high-voltage discharge or a sustained high-voltage discharge, the current increases. Therefore, in order to avoid the current from being too large and the circuit from being burnt by overheating, a preset protection current threshold is set, and the value of the preset protection current threshold is greater than that of the preset current threshold in the previous embodiment. When the working current of the ionizer is higher than the preset protection current threshold, it indicates that the voltage provided according to the current target current range is too large, the working circuit is subjected to overcurrent, and the current target current range is adjusted to reduce the output voltage and protect the working circuit of the ionizer.
In an embodiment of the invention, after the step S13 of judging that the operating current satisfies the preset target current range adjustment condition, the method further includes the following steps S131 'to S133':
s131', adjusting the target current range, reducing the minimum threshold of the target current range by a third preset value, and reducing the maximum threshold of the target current range by a fourth preset value to obtain an adjusted second target current range;
s132', the controlling the ionizer according to the adjusted target current range to adjust the output voltage of the ionizer, includes:
s133', controlling the ionizer according to the adjusted second target current range to adjust an output voltage of the ionizer.
Specifically, the current target current range (I)low，Ihigh) Minimum threshold value oflowDecrease the third preset value △ I3A maximum threshold value I of the target current rangehighBy decreasing the fourth preset value △ I4Obtaining the adjusted second target current range (I)low-△I3，Ihigh-△I4) Further, the ionizer is controlled to provide a corresponding output voltage in accordance with the adjusted second target current range, more specifically, the third preset value △ I3And said fourth preset value △ I4The value of (A) can be two preset same or different values, and can also be taken by a control program according to a preset operation logic.
In an embodiment of the present invention, the working voltage of the ionizer can be obtained in real time, and whether the obtained working voltage is greater than a preset protection voltage threshold is determined, where the preset protection voltage threshold is a maximum voltage allowed to be reached by the ionizer. Specifically, if the operating voltage is greater than the preset protection voltage threshold, the minimum threshold and the maximum threshold of the current target current range may be reduced according to the adjustment strategy described in the foregoing embodiment, so as to provide a voltage according to the adjusted target current range with a lower value, thereby preventing the actual operating voltage of the ionizer from being too high, accelerating the aging of the insulation device thereof, and causing insulation failure.
