[0076] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0077] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0078] In electronic equipment such as air conditioners and fresh air systems, streamer sterilization devices are often used for purification and sterilization. The principle of streamer sterilization devices is to perform streamer discharge, which is a special state of corona discharge. During the streamer discharge process, local air is ionized, which can produce active substances with super strong oxidizing properties, which have a significant inactivation effect on bacteria and viruses and can be used in the field of purification and sterilization.

[0079] However, in the process of ionizing the air, the streamer sterilizer will inevitably produce positive oxygen ions, negative oxygen ions and oxygen atoms. The three components react with each other to easily produce ozone. When the ozone concentration in the environment is too high, it is not good for human health and affects the user experience.

[0080] In view of the shortcomings of the above-mentioned related technologies, an embodiment of the present invention provides a method for controlling ozone concentration, which can effectively reduce the ozone concentration when the ambient ozone concentration is too high. In order to illustrate the technical solution of the present invention, a specific embodiment is used for illustration below.

[0081] Figure 1 The embodiment of the present invention provides a schematic diagram of an implementation flow of an ozone concentration control method, wherein the ozone concentration control method is performed by an electronic device, and the electronic device includes an air conditioner, a fresh air system, etc. Figure 1, the methods for controlling ozone concentration include:

[0082] S101, during the operation of the streamer sterilization device of the electronic device, determining the ozone concentration of the current environment.

[0083] In electronic equipment such as air conditioners and fresh air systems, streamer sterilization devices are often used for purification and sterilization. In the related art, there is a streamer sterilization device based on dielectric barrier discharge (DBD). The principle of the dielectric barrier discharge is a non-equilibrium gas discharge in which an insulating medium is inserted into the discharge space, that is, a gas discharge phenomenon of low-temperature discharge plasma is generated in the air gap by inserting an insulating medium into the air gap between two metal electrodes. Dielectric barrier discharge is also called dielectric barrier corona discharge or silent discharge. During the discharge process, the air will be ionized to generate plasma; it can be widely used in the production of ozone, modification, grafting, surface tension improvement, cleaning and hydrophilic modification of polymer and metal films and plates. The streamer sterilization device based on DBD can realize the function of air purification and / or sterilization. For example, integrating a streamer sterilization device on an air conditioner can efficiently kill bacteria in the air duct of the air conditioner and in the room, and purify the air well.

[0084] The DBD-based streamer sterilization device will produce ozone as a byproduct while ionizing the air and killing bacteria. When the ozone concentration in the environment is too high, it will cause certain harm to human health and affect the user experience.

[0085] Here, the ozone concentration in the current environment may be detected by an external ozone concentration sensor configured by the electronic device itself, or the ozone concentration detected by other electronic devices in the current environment may be received.

[0086] S102: If the ozone concentration is greater than or equal to a first set concentration, adjust the operating status of at least two functional modules of the electronic device.

[0087] S103, if the ozone concentration is greater than or equal to a second set concentration and less than the first set concentration, adjust the operating state of at least one functional module of the electronic device; wherein, the first set concentration is greater than the second set concentration, and the functional module is used to reduce the ozone concentration in the current environment.

[0088] This embodiment uses a corresponding adjustment mechanism to adjust the operating state of the functional module of the electronic device according to the concentration range of the ozone concentration, so as to reduce the ozone concentration in the current environment.

[0089] The first set concentration is greater than the second set concentration. For example, the first set concentration is 300 ppb (part per billion) and the second set concentration is 150 ppb.

[0090] The ozone concentration is greater than or equal to the second set concentration and less than the first set concentration. When the ozone concentration is within this concentration range, it can be considered that the ozone concentration in the current environment is slightly exceeded. For example, if the ozone concentration in the current environment is C, if 150ppb≤C<300ppb, the operating state of at least one functional module of the electronic device is adjusted.

[0091] The ozone concentration is greater than or equal to the first set concentration. When the ozone concentration is within this concentration range, it can be considered that the ozone concentration in the current environment is moderately / severely exceeded. For example, if the ozone concentration in the current environment is C, if C≥300ppb, the operating state of at least two functional modules of the electronic device is adjusted.

[0092] Exemplarily, when the ozone concentration slightly exceeds the standard, the operating state of at least one functional module of the electronic device is adjusted; when the ozone concentration moderately / severely exceeds the standard, the operating states of at least two functional modules of the electronic device are adjusted.

[0093] The functional module of the electronic device can be used to reduce the ozone concentration in the current environment, and the streamer sterilization device is also a functional module of the electronic device. Taking the air conditioner as an example, the functional module of the air conditioner also includes a fan, a humidification module and a fresh air module.

[0094] Exemplarily, the operation state of at least one functional module of the electronic device is adjusted, including: adjusting the pulse voltage frequency of the streamer sterilization device, reducing the pulse voltage frequency of the streamer sterilization device can increase the generation rate of the target product, inhibit ozone generation, and thus reduce the ozone concentration. The specific reduction level of the pulse voltage frequency can be set according to actual conditions.

[0095] Exemplarily, the adjusting the operating state of at least two functional modules of the electronic device includes: reducing the pulse voltage frequency of the streamer sterilization device and increasing the speed of the fan. Increasing the speed of the fan can speed up the flow of ambient air, achieve uniform distribution of ozone concentration in the environment, and avoid excessive local ozone concentration.

[0096] In addition, turning on the humidification module can increase the ambient humidity, which can promote the decomposition of ozone in the environment. Ozone reacts with water molecules in the environment and decomposes in the water, thereby reducing the ozone concentration in the environment. Turning on the fresh air module can allow the air in the environment to circulate with the outside world, thereby reducing the ozone concentration in the current environment.

[0097] This embodiment uses a corresponding adjustment mechanism to adjust the operating state of the functional modules of the electronic device according to the concentration range of the ozone concentration in the current environment. When the ozone concentration slightly exceeds the standard (the ozone concentration is greater than or equal to the second set concentration and less than the first set concentration), the operating state of at least one functional module of the electronic device is adjusted; when the ozone concentration moderately / severely exceeds the standard (the ozone concentration is greater than or equal to the first set concentration), the operating state of at least two functional modules of the electronic device is adjusted.

[0098] The more functional modules are adjusted, the greater the impact on the indoor environment and the greater the impact on the user's sensory experience. This embodiment adjusts the operating status of an appropriate number of functional modules according to the concentration range of ozone in the current environment, thereby minimizing the number of adjusted functional modules and ensuring user experience while reducing the ozone concentration in the current environment.

[0099] The technical solution provided by the embodiment of the present application determines the ozone concentration of the current environment during the operation of the streamer sterilization device of the electronic device. If the ozone concentration is greater than or equal to the first set concentration, the operating state of at least two functional modules of the electronic device is adjusted. If the ozone concentration is greater than or equal to the second set concentration, and less than the first set concentration, the operating state of at least one functional module of the electronic device is adjusted. Among them, the first set concentration is greater than the second set concentration, and the functional module is used to reduce the ozone concentration in the current environment. This embodiment adopts a corresponding adjustment mechanism to adjust the operating state of the functional module of the electronic device according to the concentration range of the ozone concentration in the current environment, and can reasonably adjust the number of functional modules. While reducing the ozone concentration in the current environment, it reduces the degree of influence on the operating state of each functional module in the electronic device, thereby ensuring user experience.

[0100] Exemplarily, the functional modules of the electronic device include a fan and a humidification module, and the adjusting the operating state of at least one functional module of the electronic device includes:

[0101] Increasing the wind speed of the fan;

[0102] determining the ozone concentration of the current environment after the first time period;

[0103] If the ozone concentration is greater than or equal to a third set concentration, the humidification module is started; the third set concentration is less than the second set concentration;

[0104] If the ozone concentration is less than the third set concentration, the wind speed of the fan is reduced.

[0105] Here, when the ozone concentration slightly exceeds the standard, first increase the fan speed, increase the air volume, speed up the flow of ambient air, achieve uniform distribution of ozone concentration in the environment, and avoid local ozone concentration exceeding the standard.

[0106] The wind speed of the running fan is increased, and after the electronic device continues to run for a first time, the ozone concentration of the current environment is determined again. For example, the first time period may be 3 minutes. If the ozone concentration after the first time period is greater than or equal to the third set concentration, the humidification module is started. Here, the third set concentration is less than the second set concentration, for example, the second set concentration is 150 ppb, and the third set concentration is 80 ppb.

[0107] Increasing the wind speed of the fan can achieve uniform distribution of ozone concentration in the environment. However, if the ozone concentration in the current environment is greater than the third set concentration after the first period of time, it means that the ozone concentration in the environment is still too high. Therefore, the humidification module is started to further reduce the ozone concentration in the current environment.

[0108] If the ozone concentration is less than the third set concentration, it means that the ozone concentration in the current environment is within the acceptable range for the human body, so the wind speed of the fan is reduced. For example, the wind speed can be restored to the original state, the operation state of the fan can be restored, the noise of the fan can be reduced, and the impact on the user experience can be avoided.

[0109] Starting the humidification module can increase the humidity in the environment. Ozone reacts with water molecules in the environment and can be decomposed in the water, thereby reducing the ozone concentration in the environment.

[0110] For example, in the above embodiment, after starting the humidification module, the method further includes:

[0111] determining the ozone concentration of the current environment after the second time period;

[0112] If the ozone concentration is greater than or equal to the third set concentration, reducing the pulse voltage frequency of the streamer sterilization device;

[0113] If the ozone concentration is less than the third set concentration, the wind speed of the fan is reduced and the humidification module is turned off.

[0114] Here, the electronic device starts the humidification module on the basis of increasing the wind speed of the fan, and after starting the humidification module, the electronic device continues to run for a second time period, for example, the second time period may be 3 minutes, and the ozone concentration of the current environment is determined again after the second time period.

[0115] If the ozone concentration after the second period of time is still greater than or equal to the third set concentration, the pulse voltage frequency of the streamer sterilization device is further reduced. Reducing the pulse voltage frequency of the streamer sterilization device can inhibit ozone generation, thereby reducing the ozone concentration.

[0116] If the ozone concentration is less than the third set concentration, it means that the ozone concentration in the current environment is within the acceptable range for human body, the wind speed of the fan is reduced, and the humidification module is turned off, that is, the operation state of the adjusted functional module is restored to avoid affecting the user experience.

[0117] Illustratively, in the above embodiment, the functional module of the electronic device further includes a fresh air module, and after reducing the pulse voltage frequency of the streamer sterilization device, the method further includes:

[0118] determining the ozone concentration of the current environment after the third period of time;

[0119] If the ozone concentration is greater than or equal to the third set concentration, start the fresh air module;

[0120] If the ozone concentration is less than the third set concentration, the wind speed of the fan is reduced, the humidification module is turned off, and the pulse voltage frequency is increased.

[0121] Here, the electronic device further reduces the pulse voltage frequency of the streamer sterilization device on the basis of increasing the wind speed of the fan and starting the humidification module. After reducing the pulse voltage frequency of the streamer sterilization device, the electronic device continues to operate for a third time period, for example, the third time period may be 3 minutes. After the third time period, the ozone concentration of the current environment is determined again.

[0122] If the ozone concentration after the third time period is still greater than or equal to the third set concentration, the fresh air module is further activated. Turning on the fresh air module can allow the air in the environment to circulate with the outside, thereby reducing the ozone concentration in the current environment.

[0123] If the ozone concentration after the third time is less than the third set concentration, it means that the ozone concentration in the current environment is within the acceptable range for the human body, so the wind speed of the fan is reduced, the humidification module is turned off, and the pulse voltage frequency is increased. In other words, the operating state of the adjusted functional module is restored to avoid affecting the user experience.

[0124] Exemplarily, in the above embodiment, after starting the fresh air module, the method further includes:

[0125] determining the ozone concentration of the current environment after the fourth period;

[0126] If the ozone concentration is greater than or equal to the third set concentration, determining the ozone concentration of the current environment after a fifth time period;

[0127] If the ozone concentration is less than the third set concentration, the wind speed of the fan is reduced, the humidification module is turned off, the pulse voltage frequency is increased, and the fresh air module is turned off;

[0128] If the ozone concentration is greater than or equal to the third set concentration, the streamer sterilization device is turned off.

[0129] Here, the electronic device further starts the fresh air module on the basis of increasing the wind speed of the fan, starting the humidification module, and reducing the pulse voltage frequency of the streamer sterilization device. After starting the fresh air module, the electronic device continues to operate for a fourth time period, for example, the fourth time period may be 3 minutes. After the fourth time period, the ozone concentration of the current environment is determined again.

[0130] If the ozone concentration after the fourth time period is still greater than or equal to the third set concentration, the electronic device continues to operate for a fifth time period, for example, the fifth time period may be 3 minutes, and the ozone concentration of the current environment is determined again after the fifth time period.

[0131] If the ozone concentration after the fourth time period is less than the third set concentration, the wind speed of the fan is reduced, the humidification module is turned off, the pulse voltage frequency is increased, and the fresh air module is turned off. In other words, the operating state of the previously adjusted functional modules is restored to avoid affecting the user experience.

[0132] If the ozone concentration after the fifth time period is less than the third set concentration, the wind speed of the fan is reduced, the humidification module is turned off, the pulse voltage frequency is increased, and the fresh air module is turned off. That is, the operating state of the previously adjusted functional modules is restored to avoid affecting the user experience.

[0133] If the ozone concentration after the fifth time period is still greater than or equal to the third set concentration, the streamer sterilization device is turned off, and turning off the streamer sterilization device can stop generating ozone. The electronic device can also alarm the ozone concentration, notifying the user that the ozone concentration in the current environment is too high, and suggesting that the user leave the current environment.

[0134] The reason why the fifth duration is continued after the fourth duration is to provide a certain time buffer to determine whether the ozone concentration in the current environment can be reduced.

[0135] The more functional modules are adjusted, the greater the impact on the indoor environment and the user's sensory experience. For example, increasing the fan speed will increase the noise, and increasing the humidity will cause the user to feel uncomfortable. This embodiment gradually adjusts the functional modules according to the ozone concentration in the environment, which can reduce the number of adjustment functional modules as much as possible, while reducing the ozone concentration in the current environment and ensuring the user experience.

[0136] For example, in one embodiment, the fan, humidification module, streamer sterilization device and fresh air module are adjusted in sequence. This adjustment sequence has the least impact on the user experience and the ozone concentration decreases fastest.

[0137] Exemplarily, the functional modules of the electronic device include a fan, a humidification module, the streamer sterilization device and a fresh air module;

[0138] Correspondingly, the step of adjusting the operating status of at least two functional modules of the electronic device includes at least two of the following:

[0139] Increasing the wind speed of the fan;

[0140] Starting the humidification module;

[0141] Reducing the pulse voltage frequency of the streamer sterilization device;

[0142] Starting the fresh air module;

[0143] After adjusting the operating states of at least two functional modules of the electronic device, the method further includes:

[0144] determining the ozone concentration of the current environment after the sixth period;

[0145] If the ozone concentration is still greater than or equal to the first set concentration, turn off the streamer sterilization device; or adjust the operating status of all functional modules of the electronic device.

[0146] In this embodiment, when the ozone concentration is greater than or equal to the first set concentration, the operating states of at least two functional modules of the electronic device are adjusted. For example, the wind speed of the fan is increased and the humidification module is started. After adjusting the operating states of at least two functional modules of the electronic device, the electronic device continues to operate for a sixth time period, for example, the sixth time period may be 4 minutes. After the sixth time period, the ozone concentration of the current environment is determined again.

[0147] Here, if the ozone concentration after the sixth period of time is still greater than or equal to the first set concentration, there are two adjustment schemes to choose from, and one of the two adjustment schemes can be selected.

[0148] The first adjustment scheme is to turn off the streamer sterilization device, which can stop the generation of ozone. The electronic device can also issue an ozone concentration alarm to inform the user that the ozone concentration in the current environment is too high and recommend the user to leave the current environment. Alternatively, the second adjustment scheme is to adjust the operating status of all functional modules of the electronic device to reduce the ozone concentration as much as possible.

[0149] Exemplarily, in the above embodiment, after determining the ozone concentration of the current environment after the sixth time period, the method further includes:

[0150] If the ozone concentration is greater than or equal to the third set concentration and less than the second set concentration, the ozone concentration of the current environment is determined again after a fifth period of time; the third set concentration is less than the second set concentration;

[0151] If the ozone concentration after the fifth time period is less than the third set concentration, restoring the operating state of the at least two functional modules;

[0152] If the ozone concentration after the fifth period of time is still greater than or equal to the third set concentration, the streamer sterilization device is turned off.

[0153] Here, corresponding to the solution of the aforementioned embodiment, if the ozone concentration after the fifth period of time is less than the third set concentration, the operating state of the previously adjusted functional module is restored to avoid affecting the user experience.

[0154] If the ozone concentration of the fifth time period is still greater than or equal to the third set concentration, the streamer sterilization device is turned off, and turning off the streamer sterilization device can stop generating ozone. The electronic device can also alarm the ozone concentration, notifying the user that the ozone concentration in the current environment is too high, and suggesting that the user leave the current environment.

[0155] Exemplarily, in the above embodiment, after adjusting the operating states of all functional modules of the electronic device, the method further includes:

[0156] After the seventh period, the ozone concentration of the current environment is determined;

[0157] If the ozone concentration is still greater than or equal to the first set concentration, the streamer sterilization device is turned off.

[0158] Adjusting the operating status of all functional modules of the electronic device can be: increasing the wind speed of the fan, starting the humidification module, reducing the pulse voltage frequency of the streamer sterilization device and starting the fresh air module, and adjusting the operating status of the above four functional modules at the same time.

[0159] After adjusting the operating states of all functional modules of the electronic device, the electronic device continues to operate for a seventh time period, for example, the seventh time period may be 4 minutes. After the seventh time period, the ozone concentration of the current environment is determined again. If the ozone concentration after the seventh time period is still greater than or equal to the first set concentration, the streamer sterilization device is turned off.

[0160] In addition, this embodiment may further include: if the ozone concentration after the seventh time period is greater than or equal to the third set concentration and less than the second set concentration, determining the ozone concentration of the current environment again after the fifth time period; the third set concentration is less than the second set concentration;

[0161] If the ozone concentration after the fifth time period is less than the third set concentration, restoring the operating state of the at least two functional modules;

[0162] If the ozone concentration after the fifth period of time is still greater than or equal to the third set concentration, the streamer sterilization device is turned off.

[0163] This embodiment adjusts the operating states of an appropriate number of functional modules according to the concentration range of ozone in the current environment, thereby reducing the ozone concentration in the current environment while ensuring user experience.

[0164] Exemplarily, the method further includes:

[0165] If the ozone concentration is greater than or equal to a fourth set concentration, the operating states of all functional modules of the electronic device are adjusted; the fourth set concentration is greater than the first set concentration; the first set concentration is less than the fourth set concentration.

[0166] This embodiment divides the concentration into three sections, and each section corresponds to a different regulation mechanism.

[0167] Here, the fourth set concentration is greater than the first set concentration. If the ozone concentration is greater than or equal to the first set concentration and less than the fourth set concentration, it means that the ozone concentration is moderately exceeded. If the ozone concentration is greater than or equal to the fourth set concentration, it means that the ozone concentration is severely exceeded.

[0168] When the ozone concentration exceeds the standard seriously, the operating status of all functional modules of the electronic equipment is adjusted.

[0169] Exemplarily, the functional modules of the electronic device include a fan, a humidification module, the streamer sterilization device and a fresh air module; and the step of adjusting the operating status of all the functional modules of the electronic device includes:

[0170] Increasing the wind speed of the fan;

[0171] Starting the humidification module;

[0172] Reducing the pulse voltage frequency of the streamer sterilization device;

[0173] Start the fresh air module.

[0174] Exemplarily, after adjusting the operating status of all functional modules of the electronic device, the method further includes:

[0175] After the seventh period, the ozone concentration of the current environment is determined;

[0176] If the ozone concentration is still greater than or equal to the fourth set concentration, turning off the streamer sterilization device;

[0177] If the ozone concentration is greater than or equal to the third set concentration and less than the second set concentration, the ozone concentration of the current environment is determined again after a fifth period of time; the third set concentration is less than the second set concentration;

[0178] If the ozone concentration is less than the third set concentration, restoring the operating state of the at least two functional modules;

[0179] If the ozone concentration after the fifth period of time is still greater than or equal to the third set concentration, the streamer sterilization device is turned off.

[0180] After adjusting the operating states of all functional modules of the electronic device, the electronic device continues to operate for a seventh time period, for example, the seventh time period may be 4 minutes. After the seventh time period, the ozone concentration of the current environment is determined again. If the ozone concentration after the seventh time period is still greater than or equal to the fourth set concentration, the streamer sterilization device is turned off.

[0181] Several other situations correspond to the schemes of the aforementioned embodiments, namely: if the ozone concentration is greater than or equal to the third set concentration and less than the second set concentration, the ozone concentration of the current environment is determined again after the fifth time period; the third set concentration is less than the second set concentration; if the ozone concentration is less than the third set concentration, the operating state of the at least two functional modules is restored; if the ozone concentration after the fifth time period is still greater than or equal to the third set concentration, the streamer sterilization device is turned off. The specific implementation process is detailed in the aforementioned method embodiment and will not be repeated here.

[0182] In summary, exemplarily, the embodiment of the present invention divides the concentration range into three ranges, each of which has its corresponding adjustment mechanism, which can reasonably adjust the number of functional modules according to the concentration range. While reducing the ozone concentration in the current environment, it reduces the impact on the operating status of each functional module in the electronic device, thereby ensuring the user experience.

[0183] refer to Figure 2 , Figure 2 This is a structural block diagram of a solution for reducing ozone concentration provided by an application embodiment of the present invention. Among them, the ozone detection part: the main function is to collect the change of ozone concentration in the environment through an ozone sensor outside the machine, and provide a signal source for the subsequent comparison output part.

[0184] Comparison output part: Through the comparator, the ozone sensor signal is compared with the reference potential and high and low levels are output.

[0185] Control operation part: After receiving the signal output by the comparator, the microcontroller unit (MCU) adjusts the operation status of the functional modules of the electronic equipment according to the logic set by the control program. These include the wind speed adjustment module, humidity adjustment module, voltage adjustment module and fresh air adjustment module. The operation control part can adjust the operation status of each functional module in real time through ozone monitoring.

[0186] The ozone detection part converts the ambient ozone concentration signal into a voltage signal, and outputs a high or low level by comparing it with the reference voltage. The operation control part adjusts the operation status of each functional module through high and low level signals to control the ambient ozone concentration.

[0187] This solution collects ozone concentration data in the environment, realizes the linkage between ozone concentration and humidity, wind speed, fresh air, and voltage, and reduces the ozone concentration in the environment. When the ozone concentration in the environment is detected to be higher than the set threshold, the ambient ozone concentration is quickly reduced by increasing the ambient humidity, increasing the ambient wind speed, introducing outdoor fresh air, and increasing the output voltage pulse frequency.

[0232] In this embodiment, when the ozone concentration seriously exceeds the standard, different functional modules are turned on at the same time, thereby solving the problem of excessively high ambient ozone concentration while ensuring the sterilization efficiency.

[0233] In the above embodiment, the streamer sterilization device includes a plasma generator. Exemplarily, the plasma generator may be a dielectric barrier discharge generator for dielectric barrier discharge.

[0234] Figure 5 Schematic diagram of the structure of a streamer sterilization device according to an embodiment of the present application. Figure 5 As shown, the device may include a signal generating circuit 10, an oscillating circuit 20, a voltage signal processing circuit 30 and a plasma generator 40 connected in sequence; wherein,

[0235] The signal generating circuit 10 is powered by a direct current power supply DC, and is used to generate a driving signal and output the driving signal to the oscillation circuit 20. For example, the driving signal may be a square wave pulse signal.

[0236] The oscillation circuit 20 is used to receive a DC voltage signal, convert the DC voltage signal into an AC voltage signal based on the driving signal, and output the AC voltage signal to the voltage signal processing circuit 30. For example, the DC voltage signal received by the oscillation circuit 20 may be a voltage signal of a DC power supply.

[0237] The voltage signal processing circuit 30 is at least used for performing voltage boost processing on the AC voltage signal to obtain a first square wave pulse signal, and outputting the first square wave pulse signal to the plasma generator 40 .

[0238] In some embodiments, reference Figure 6 and Figure 7 The signal generating circuit 10 includes a control signal generating circuit 101 and a driving signal generating circuit 102 .

[0239] Exemplarily, the control signal generating circuit 101 can output the control signal through the air conditioner indoor unit electronic control, or crystal oscillator chip, or digital chip, or operational amplifier RC resonance mode, where the control signal is a basic square wave pulse signal with a small voltage.

[0240] In actual scenarios, the voltage amplitude of the basic square wave pulse signal can be adjusted according to actual needs. Figure 8 , the voltage of the high-level signal of the basic square wave pulse signal is V1, and the duration of the high-level signal of the basic square wave pulse signal in one signal cycle is t1; the voltage of the high-level signal of the basic square wave pulse signal is V2, and the duration of the low-level signal of the basic square wave pulse signal in one signal cycle is t2; the value range of V1 and V2 can be 0 to 10V, V1>V2, it can be seen that the frequency f of the basic square wave pulse signal is 1 / (t1+t2), and the duty cycle d of the basic square wave pulse signal is t1 / (t1+t2).

[0241] Exemplarily, the driving signal generating circuit 102 is used to adjust at least one of the voltage value, frequency and duty cycle of the basic square wave pulse signal, and output the adjusted driving signal to the oscillation circuit 20 .

[0242] Exemplarily, the oscillation circuit 20 can oscillate the DC voltage signal into an AC voltage signal according to the driving signal and in the form of a transistor switch, and the oscillation frequency of the oscillation circuit 20 can be between 20 kHz and 100 kHz. The oscillation amplitude of the oscillation circuit 20 is determined by the voltage value of the driving signal.

[0243] In one example, the voltage signal processing circuit 30 may include a boost circuit for boosting the AC voltage signal, and a rectifier circuit; the rectifier circuit is used to rectify the boosted AC voltage signal to obtain a first square wave pulse signal, and output the first square wave pulse signal to the plasma generator.

[0244] In another example, the voltage signal processing circuit 30 may include a transformer and a voltage doubling rectifier circuit. The transformer can boost the voltage signal, the voltage amplification factor of the transformer is the turns ratio n of the transformer, and the calculation formula of the voltage value b of the voltage signal output by the secondary coil of the transformer is:

[0245] b=a*n

[0246] Where a represents the voltage value of the primary coil of the transformer.

[0247] After the driving signal is amplified by the transistor of the oscillation circuit 20 , it can be output to the transformer of the voltage signal processing circuit 30 ; the first output terminal, the second output terminal, the third output terminal and the fourth output terminal of the oscillation circuit 20 are connected to the transformer of the voltage signal processing circuit 30 .

[0248] Reference Fig. 9 The HV end of the plasma generator 40 is connected to the output end of the voltage doubling rectifier circuit, the LV end of the plasma generator 40 can be grounded, and the plasma generator 40 may include an anode, a cathode, a sixth resistor R6, a seventh resistor R7, an eighth resistor R8, a ninth resistor R9, a tenth resistor R10, an eleventh resistor R11, a twelfth resistor R12, a thirteenth resistor R13 and a fourteenth resistor R14, wherein the anode of the plasma generator 40 is respectively connected to the eleventh resistor R11, the twelfth resistor R12 and the high voltage direct current (HVDC) interface, and the cathode of the plasma generator 40 is connected to the thirteenth resistor R13. Exemplarily, the sixth resistor R6, the seventh resistor R7, the eighth resistor R8, the ninth resistor R9, the tenth resistor R10, the thirteenth resistor R13 and the fourteenth resistor R14 are all models 2010-246-F-1 / 2W-T, and the eleventh resistor R11 and the twelfth resistor R12 are all models 2010-105-F-1 / 2W-T.

[0249] In an embodiment of the present application, after the first square wave pulse signal is output to the plasma generator 40, the plasma generator 40 can be driven to work by the first square wave pulse signal. When the voltage value of the low level signal of the first square wave pulse signal is low, if the plasma generator 40 is driven to work based on the low level signal of the first square wave pulse signal, the ozone concentration in the surrounding environment of the plasma generator 40 can be reduced.

[0250] Therefore, reducing the pulse voltage frequency of the streamer sterilization device in the embodiment of the present application may be to reduce the voltage value of the low-level signal of the square wave pulse signal of the plasma generator, so that the ozone concentration in the environment around the plasma generator is reduced.

[0251] It can be seen that the embodiment of the present application can utilize a signal generating circuit, an oscillation circuit, and a voltage signal processing circuit to generate a first square wave pulse signal for driving the plasma generator to operate. Therefore, the plasma generator can achieve efficient air purification based on the high-level signal of the first square wave pulse signal, and can also achieve air purification based on the low-level signal of the first square wave pulse signal. Compared with the scheme of using a constant voltage to drive the plasma generator to operate in the related art, the embodiment of the present application uses the low-level signal of the first square wave pulse signal as the driving signal of the plasma generator, which is beneficial to reducing the driving voltage of the plasma generator, thereby helping to reduce the ozone concentration in the environment surrounding the plasma generator.

[0252] In some embodiments of the present application, the driving signal generating circuit 102 is also used to determine the frequency of the basic square wave pulse signal as the frequency of the driving signal. It can be seen that since the oscillation circuit converts the DC voltage signal into an AC voltage signal according to the driving signal, and the voltage signal processing circuit can convert the input AC voltage signal into the first square wave pulse signal received by the plasma generator, therefore, by determining the frequency of the basic square wave pulse signal as the frequency of the driving signal, the frequency of the first square wave pulse signal can be made equal to the frequency of the basic square wave pulse signal; further, since the frequency of the basic square wave pulse signal can be determined by the control signal generating circuit according to actual needs, therefore, the embodiment of the present application can flexibly control the frequency of the first square wave pulse signal received by the plasma generator according to actual needs.

[0253] In some embodiments of the present application, reference Figure 6 The streamer sterilization device further includes a first sampling circuit 50 , and a sampling end of the first sampling circuit 50 is connected to the oscillation circuit 20 .

[0254] The signal generating circuit 10 may include a control signal generating circuit 101 and a drive signal generating circuit 102; the output end of the control signal generating circuit 101 is connected to the first input end of the drive signal generating circuit 102, the output end of the first sampling circuit 50 is connected to the second input end of the drive signal generating circuit 102; the output end of the drive signal generating circuit 102 is connected to the input end of the oscillation circuit 20.

[0255] It can be seen that the drive signal generating circuit can control the voltage value of the drive signal output by itself according to the signal output by the control signal generating circuit and the signal output by the first sampling circuit. Therefore, the embodiment of the present application can realize the adjustment of the voltage value of the output signal of the oscillation circuit, thereby realizing the adjustment of the voltage value of the signal received by the plasma generator.

[0256] In some embodiments, the first sampling circuit 50 is used to step down the output signal of the oscillation circuit 20 into a second square wave pulse signal, and output the second square wave pulse signal to the drive signal generating circuit 102; the low level signal and the high level signal in the second square wave pulse signal are both positive voltage signals.

[0257] The control signal generating circuit 101 is used to generate a basic square wave pulse signal, and output the basic square wave pulse signal to the driving signal generating circuit 102; the low level signal and the high level signal in the basic square wave pulse signal are both positive voltage signals.

[0258] The drive signal generating circuit 102 is used to compare the voltage values ​​of the basic square wave pulse signal and the second square wave pulse signal to obtain a first comparison result, and adjust the voltage value of the drive signal output by the drive signal generating circuit 102 according to the first comparison result so that the voltage values ​​of the basic square wave pulse signal and the second square wave pulse signal are equal.

[0259] Here, the first sampling circuit 50 can convert the AC voltage signal before transformer amplification into a DC square wave pulse signal, so that the driving signal generation circuit compares the square wave pulse signal fed back by the first sampling circuit 50 with the basic square wave pulse signal. For example, the voltage value of the DC square wave pulse signal is between 0 and 5V.

[0260] It can be seen that the drive signal generating circuit can control the voltage value of the drive signal output by itself according to the voltage values ​​of the basic square wave pulse signal and the second square wave pulse signal, so that the voltage values ​​of the basic square wave pulse signal and the second square wave pulse signal are equal. In this way, the embodiment of the present application can control the voltage value of the second square wave pulse signal through the drive signal generating circuit; since the second square wave pulse signal is a voltage signal obtained after the output signal of the oscillation circuit is stepped down, the embodiment of the present application can realize the adjustment of the voltage value of the output signal of the oscillation circuit, thereby realizing the adjustment of the voltage value of the signal received by the plasma generator.

[0261] In some embodiments of the present application, reference Figure 7 The streamer sterilization device also includes a second sampling circuit 60 , and the second sampling circuit 60 is connected to the voltage signal processing circuit 30 .

[0262] The sampling end of the second sampling circuit 60 is connected to the voltage signal processing circuit 30; the output end of the control signal generating circuit 101 is connected to the first input end of the drive signal generating circuit 102, and the output end of the second sampling circuit 60 is connected to the second input end of the drive signal generating circuit 102; the output end of the drive signal generating circuit 102 is connected to the input end of the oscillation circuit 20.

[0263] It can be seen that the driving signal generating circuit can control the voltage value of the driving signal output by itself according to the signal output by the control signal generating circuit and the signal output by the second sampling circuit. Therefore, the embodiment of the present application can realize the adjustment of the voltage value of the output signal of the oscillation circuit, thereby realizing the adjustment of the voltage value of the signal received by the plasma generator.

[0264] In some embodiments, the second sampling circuit 60 is used to step down the output signal of the voltage signal processing circuit 30 into a third square wave pulse signal, and output the third square wave pulse signal to the drive signal generating circuit; the low level signal and the high level signal in the fourth square wave pulse signal are both positive voltage signals.

[0265] The control signal generating circuit 102 is used to generate a basic square wave pulse signal and output the basic square wave pulse signal to the driving signal generating circuit 102; the low level signal and the high level signal in the basic square wave pulse signal are both positive voltage signals.

[0266] The driving signal generating circuit 102 is used to compare the voltage values ​​of the basic square wave pulse signal and the third-party wave pulse signal to obtain a second comparison result, and adjust the voltage value of the driving signal according to the second comparison result to make the voltage values ​​of the basic square wave pulse signal and the third-party wave pulse signal equal.

[0267] Here, the second sampling circuit 60 can convert the high-voltage square wave pulse signal output by the voltage signal processing circuit into a low-voltage third-wave pulse signal, so that the driving signal generating circuit compares the square wave pulse signal fed back by the second sampling circuit 60 with the basic square wave pulse signal. For example, the second sampling circuit 60 can convert the high-voltage square wave pulse signal output by the voltage signal processing circuit into a low-voltage third-wave pulse signal according to a voltage reduction factor of 2000 times.

[0268] It can be seen that the driving signal generating circuit can control the voltage value of the driving signal output by itself according to the voltage values ​​of the basic square wave pulse signal and the third-party wave pulse signal, so that the voltage values ​​of the basic square wave pulse signal and the third-party wave pulse signal are equal. In this way, the embodiment of the present application can control the voltage value of the third-party wave pulse signal through the driving signal generating circuit; since the third-party wave pulse signal is a voltage signal obtained by step-down conversion of the output signal of the voltage signal processing circuit, the embodiment of the present application can realize the adjustment of the voltage value of the output signal of the oscillation circuit, thereby realizing the adjustment of the voltage value of the signal received by the plasma generator.

[0269] In some embodiments of the present application, a high-level signal or a low-level signal is recorded as a target type signal; the absolute value of the voltage value of the target type signal in the first square wave pulse signal is positively correlated with the voltage value of the target type signal of the second square wave pulse signal; that is, when the first square wave pulse signal output by the voltage signal processing circuit 30 is a positive voltage signal, the higher the voltage value of the target type signal in the first square wave pulse signal, the higher the voltage value of the target type signal of the second square wave pulse signal; when the first square wave pulse signal output by the voltage signal processing circuit 30 is a negative voltage signal, the higher the absolute value of the voltage value of the target type signal in the first square wave pulse signal, the higher the voltage value of the target type signal of the second square wave pulse signal.

[0270] In the embodiment of the present application, the voltage value of the target type signal of the basic square wave pulse signal is recorded as the first voltage value, and the voltage value of the target type signal of the second square wave pulse signal is recorded as the second voltage value. The drive signal generating circuit 102 is used to increase the voltage value of the drive signal when the first voltage value is greater than the second voltage value, and to reduce the voltage value of the drive signal when the first voltage value is less than the second voltage value, so that the first voltage value is equal to the second voltage value.

[0271] It can be seen that the drive signal generating circuit can control the voltage value of the drive signal output by itself by comparing the voltage value of the target type signal of the basic square wave pulse signal with the voltage value of the target type signal of the second square wave pulse signal. When the voltage value of the target type signal of the basic square wave pulse signal and the voltage value of the target type signal of the second square wave pulse signal are not equal, the voltage value of the basic square wave pulse signal and the voltage value of the second square wave pulse signal are made equal by adjusting the voltage value of the drive signal output by itself. In this way, the embodiment of the present application can control the voltage value of the second square wave pulse signal through the drive signal generating circuit; since the second square wave pulse signal is a voltage signal obtained after the output signal of the oscillation circuit is stepped down, the embodiment of the present application can realize the adjustment of the voltage value of the output signal of the oscillation circuit, thereby realizing the adjustment of the voltage value of the signal received by the plasma generator.

[0272] The embodiment of the present application proposes a streamer sterilization device, which can be applied to indoor air conditioning sterilization, deodorization and other scenarios. The embodiment of the present application can use a square wave pulse signal to drive the plasma generator to work. When the high-level signal of the square wave pulse signal is used to drive the plasma generator to work, the effect of ionizing the air can be improved, and the air purification effect can be improved; by switching the high and low levels of the square wave pulse signal, the plasma generator can generate a changing electric field, thereby enhancing the air purification effect. At the same time, using the low-level signal of the square wave pulse signal to drive the plasma generator to work can reduce the ozone concentration to a certain extent. The embodiment of the present application can solve the problem that the higher the voltage of the plasma generator, the better the air purification effect, but the voltage increase causes the ozone to exceed the standard and cannot be used in the indoor environment. It can realize the combined application of a plasma generator driven by a high-voltage square wave pulse signal and air conditioning to purify the air.

The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiment of the present invention.
