Description

Technical Field

[0001] This invention relates to the field of atomization technology, and in particular to an atomizing plate driving method, apparatus, atomizer, and computer-readable storage medium. Background Technology

[0002] Ultrasonic atomization uses the high-frequency resonance of a ceramic atomizing plate to break down the liquid water molecules and produce a naturally drifting water mist. It does not require heating or the addition of any chemical reagents. During the atomization process, a large number of negative ions are released, which react electrostatically with smoke, dust and other particles floating in the air, causing them to settle. At the same time, it can effectively remove harmful substances such as formaldehyde, carbon monoxide, and bacteria, thus purifying the air and reducing the occurrence of diseases.

[0003] In existing technologies, ultrasonic atomizers adjust the atomization volume using a fixed frequency or a fixed duty cycle, or a combination of both. However, in practical applications, since the spray volume of the atomizer changes constantly according to demand during operation, relying solely on a fixed frequency or a fixed duty cycle, or a combination of both, may result in the atomization effect of the atomizer not reaching its optimal level. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art.

[0005] Therefore, one objective of this invention is to provide an atomizing plate driving method that can adjust the atomization volume, thereby avoiding situations where the atomization volume of the atomizer does not increase, does not decrease, or does not produce mist after adjusting the duty cycle, and where the human eye cannot distinguish the mist size under different duty cycles, thus improving the atomization effect.

[0006] Therefore, a second objective of the present invention is to provide an atomizing plate driving device.

[0007] Therefore, a third objective of this invention is to provide an atomizer.

[0008] Therefore, a fourth object of the present invention is to provide a computer-readable storage medium.

[0009] To achieve the above objectives, an embodiment of the first aspect of the present invention discloses an atomizing plate driving method, comprising: upon receiving a power-on command, performing frequency tracking of the atomizing plate in response to the power-on command; determining whether frequency tracking is successful; if so, configuring multiple operating duty cycles for the atomizing plate; and controlling the atomizing plate to operate according to the multiple operating duty cycles in time periods.

[0010] According to the atomizing plate driving method of the present invention, when the atomizer receives a power-on command, the atomizing plate can be frequency tracked. Based on the frequency tracking judgment result of the atomizing plate, multiple operating duty cycles are configured for the atomizing plate. The atomizing plate is controlled to execute different operating strategies according to multiple operating duty cycles in different time periods, thereby adjusting the atomization volume. This avoids situations where the atomization volume of the atomizer does not increase, does not decrease, or does not produce mist after adjusting the duty cycle, and the human eye cannot distinguish the mist size under different duty cycles, thus improving the atomization effect.

[0011] In addition, the atomizing plate driving method according to the above embodiments of the present invention may also have the following additional technical features:

[0012] In some examples, determining whether frequency tracking was successful includes: determining whether the target frequency was reached; if so, frequency tracking is determined to be successful; otherwise, frequency tracking is determined to be unsuccessful.

[0013] In some examples, determining whether the frequency has been tracked to the target frequency includes: determining whether the current flowing through the atomizing plate is within a preset current range; if so, determining that the frequency has been tracked to the target frequency; otherwise, determining that the frequency has not been tracked to the target frequency.

[0014] In some examples, determining whether the target frequency has been reached includes: determining whether the mist output of the atomizing plate is greater than a preset mist output, whether the power of the atomizing plate is less than a preset power, whether the temperature of the components of the driving circuit driving the atomizing plate is within a preset temperature range, and whether the peak voltage across the atomizing plate is within a preset vibration voltage range; if so, it is determined that the target frequency has been reached; otherwise, it is determined that the target frequency has not been reached.

[0015] In some examples, configuring multiple operating duty cycles for the atomizing plate includes configuring multiple different operating duty cycles one-to-one in multiple time intervals based on the target frequency.

[0016] In some examples, controlling the atomizing plate to operate according to multiple operating duty cycles in different time periods includes: controlling the atomizing plate to operate according to the corresponding operating duty cycle in each time interval.

[0017] In some examples, the sum of the times of the multiple time intervals is equal to a set time period, and the length of each time interval is greater than a set unit time period and the length of each time interval is a multiple of the unit time period, wherein the unit time period is obtained by dividing the set time period into multiple time periods.

[0018] In some examples, the values ​​of multiple operating duty cycles decrease sequentially according to the order of the multiple time intervals, and the value of the first operating duty cycle configured in the first time interval is less than the reciprocal of the target frequency.

[0019] In some examples, the absolute value of the difference between two adjacent operating duty cycles does not exceed a preset difference.

[0020] In some examples, the preset difference is a preset percentage of the current operating duty cycle of the atomizer.

[0021] In some examples, the preset percentage includes 2%-5%.

[0022] To achieve the above objectives, a second aspect of the present invention discloses an atomizing plate driving device, comprising: a processing module, configured to receive a power-on command and, in response to the power-on command, perform frequency tracking processing on the atomizing plate; a judgment module, configured to determine whether frequency tracking is successful; a configuration module, configured to configure multiple operating duty cycles for the atomizing plate when frequency tracking is successful; and a control module, configured to control the atomizing plate to operate according to the multiple operating duty cycles in different time periods.

[0023] According to the atomizing plate driving device of the present invention, when the atomizer receives a power-on command, the atomizing plate can be frequency tracked. Based on the frequency tracking judgment result, multiple operating duty cycles are configured for the atomizing plate. The atomizing plate is controlled to execute different operating strategies according to multiple operating duty cycles in different time periods, thereby adjusting the atomization volume. This avoids situations where the atomization volume of the atomizer does not increase, does not decrease, or does not produce mist after adjusting the duty cycle, and the human eye cannot distinguish the mist size under different duty cycles, thus improving the atomization effect.

[0024] To achieve the above objectives, a third aspect of the present invention discloses an atomizer comprising: an atomizing plate; and an atomizing plate driving device as described in the second aspect of the present invention; or, a processor, a memory, and an atomizing plate driver program stored in the memory and executable on the processor, wherein the atomizing plate driver program, when executed by the processor, implements the atomizing plate driving method as described in the first aspect of the present invention.

[0025] According to the atomizer of the present invention, when the atomizer receives a power-on command, it can perform frequency tracking on the atomizing plate. Based on the frequency tracking result of the atomizing plate, multiple operating duty cycles are configured for the atomizing plate. The atomizing plate is controlled to execute different operating strategies according to multiple operating duty cycles in different time periods, thereby adjusting the atomization volume. This avoids situations where the atomization volume of the atomizer does not increase, does not decrease, or does not produce mist after adjusting the duty cycle, and the human eye cannot distinguish the mist size under different duty cycles, thus improving the atomization effect.

[0026] To achieve the above objectives, a fourth aspect of the present invention discloses a computer-readable storage medium storing an atomizing plate driver program, wherein the atomizing plate driver program, when executed by a processor, implements the atomizing plate driving method as described in the first aspect of the present invention.

[0027] According to an embodiment of the present invention, when the atomizing plate driver stored thereon is executed by a processor, it can perform frequency tracking on the atomizing plate when the atomizer receives a power-on command. Based on the frequency tracking result of the atomizing plate, multiple operating duty cycles are configured for the atomizing plate, and the atomizing plate is controlled to execute different operating strategies according to multiple operating duty cycles in different time periods, thereby adjusting the atomization volume. This avoids situations where the atomization volume of the atomizer does not increase, does not decrease, or does not produce mist after adjusting the duty cycle, and the human eye cannot distinguish the mist size under different duty cycles, thus improving the atomization effect.

[0036] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0037] The following is for reference. Figures 1-4This invention describes an atomizing plate driving method, apparatus, atomizer, and computer-readable storage medium according to embodiments of the present invention.

[0038] Figure 1 This is a schematic flowchart of an atomizing plate driving method according to an embodiment of the present invention. Figure 1 As shown, the atomizing plate driving method includes:

[0039] Step S1: Upon receiving the power-on command, the frequency of the atomizing plate is tracked in response to the power-on command.

[0040] Specifically, when the atomizer's control system receives a power-on command, it can initiate the frequency tracking process of the atomizing plate in response to the command. The power-on command includes, but is not limited to, a trigger signal from the user pressing the power button or sent via other devices. Furthermore, frequency tracking can be achieved by feeding back the voltage to the chip's detection pin through a frequency tracking circuit. This frequency tracking circuit can be one or more oscillators or similar components used to generate and adjust the signals used to drive the atomizing plate.

[0041] Step S2: Determine if frequency tracking was successful.

[0042] Specifically, after the atomizer's control system responds to the power-on command, it can detect and acquire various parameters during the frequency tracking process of the atomizing plate, such as current and voltage, and record them. These parameters are then compared with preset optimal parameter ranges. If the parameters during frequency tracking are within the preset optimal range, frequency tracking is considered successful; otherwise, it is considered a failure. Alternatively, the system can judge based on the surface phenomena of the mist output. If the atomizing plate can produce mist normally with a large mist volume and low power, frequency tracking is considered successful. If the mist volume is very small or there is no mist output, and the atomizing plate power is high, frequency tracking is considered a failure.

[0043] Step S3: If so, configure multiple operating duty cycles for the atomizing plate.

[0044] Specifically, once the atomizing plate is successfully frequency-tracked, its optimal frequency fk0 can be obtained. This allows for the configuration of multiple operating duty cycles, such as p1, p2…p(x), enabling precise control of the atomizing plate and ultimately achieving optimal atomization. In essence, by configuring multiple operating duty cycles, the atomizer can control the vibration state and output power of the atomizing plate, thereby adjusting the amount and distribution of mist to achieve the best atomization effect.

[0045] Step S4: Control the atomizing plate to operate according to multiple duty cycles in different time periods.

[0046] Specifically, during atomizer operation, the atomizing plate can be controlled to operate at different duty cycles within different time periods. That is, within each time period, the atomizer can control the operating state of the atomizing plate according to a set duty cycle, and each duty cycle corresponds to the operating state within that time period, achieving the optimal atomization effect. Furthermore, by setting multiple duty cycles within multiple time periods, the frequency of the atomizing plate can be kept at the optimal frequency, thus ensuring that the peak voltage across the atomizing plate remains within the optimal vibration voltage range. Voltage within the optimal vibration voltage range will not damage the atomizing plate, and it also allows various factors such as atomization volume and temperature changes to meet actual requirements, thereby improving the atomization effect.

[0047] Therefore, the above-mentioned atomizing plate driving method can track the frequency of the atomizing plate when the atomizer receives the power-on command. Based on the frequency tracking result, multiple operating duty cycles are configured for the atomizing plate. The atomizing plate is controlled to execute different operating strategies according to multiple operating duty cycles in different time periods, thereby adjusting the atomization volume. This avoids situations where the atomization volume of the atomizer does not increase, does not decrease, or does not produce mist after adjusting the duty cycle, and the human eye cannot distinguish the mist size under different duty cycles, thus improving the atomization effect.

[0048] In one embodiment of the present invention, determining whether frequency tracking is successful includes: determining whether the target frequency has been reached; if so, frequency tracking is determined to be successful; otherwise, frequency tracking is determined to be unsuccessful.

[0049] Specifically, when the atomizer receives the power-on command, during the frequency tracking process of the atomizing plate, the frequency of the atomizing plate can be monitored in real time until the frequency tracking conditions are met, i.e., the optimal frequency of the atomizing plate is reached. Specifically, before starting frequency tracking, a target frequency can be set according to actual needs. While monitoring the atomizing plate frequency, the actual frequency can be compared with the target frequency to determine whether frequency tracking is successful. If the actual frequency reaches the target frequency, i.e., the target frequency has been reached, then frequency tracking is considered successful; if the actual frequency does not reach the target frequency, then frequency tracking is considered unsuccessful.

[0050] In one embodiment of the present invention, determining whether the target frequency has been reached includes: determining whether the current flowing through the atomizing plate is within a preset current range; if so, determining that the target frequency has been reached; otherwise, determining that the target frequency has not been reached.

[0051] Specifically, during the frequency tracking process of the atomizing plate, the current flowing through it will change accordingly. Whether the target frequency has been reached can be determined by whether the current flowing through the atomizing plate is within a preset current range. Specifically, for example... Figure 2As shown, the PWM (Pulse Width Modulation) signal is output from the control chip's output pin, then boosted by a MOSFET and inductor to drive the atomizer (i.e., the CN072 terminal, which is used to connect to the atomizer). The boosted current flows into the atomizer through pin 2 of CN072, then out through pin 1, and after being divided by R077 and R078, flows into the chip's detection pin from CUR. Internally, the chip converts the current into a corresponding AD value using an AD converter. By comparing the detected AD value with the set range, it determines whether the current frequency is the optimal frequency, i.e., whether it has reached the target frequency. In essence, if the detected AD value is within the set range, it is determined that the target frequency has been reached; otherwise, it is determined that the target frequency has not been reached.

[0052] In one embodiment of the present invention, determining whether the target frequency has been reached includes: determining whether the mist output of the atomizing plate is greater than a preset mist output, whether the power of the atomizing plate is less than a preset power, whether the temperature of the components of the driving circuit driving the atomizing plate is within a preset temperature range, and whether the voltage peak at both ends of the atomizing plate is within a preset vibration voltage range; if so, it is determined that the target frequency has been reached; otherwise, it is determined whether the target frequency has been reached.

[0053] Specifically, during the frequency tracking process of the atomizing plate, the determination of whether the target frequency has been reached can be based on the results of the mist output, the power of the atomizing plate, the temperature of the components in the driving circuit driving the atomizing plate, and the peak voltage across the atomizing plate. Specifically, if the mist output is greater than the preset output, it is considered a large output; if the power is less than the preset power, it is considered a low power; if the temperature of the components in the driving circuit driving the atomizing plate is within the preset temperature range, it is considered a low temperature rise; and if the peak voltage across the atomizing plate is within the preset vibration voltage range, then the target frequency has been reached. Otherwise, it is determined whether the target frequency has been reached. It is understandable that the preset mist output, preset power, preset temperature range, and preset vibration voltage range are preset values ​​or ranges that can be set according to actual needs. For example, the preset temperature range includes 40–60 degrees Celsius. Within the preset vibration voltage range, which is the optimal vibration range, the voltage will not damage the atomizing plate while meeting the actual requirements for atomization output, temperature rise, and other factors.

[0054] In one embodiment of the present invention, multiple operating duty cycles are configured for the atomizing plate, including: configuring multiple different operating duty cycles one-to-one in multiple time intervals based on the target frequency.

[0055] Specifically, when the atomizing sheet successfully tracks the frequency, the optimal frequency fk0 of the atomizing sheet, that is, the target frequency, can be obtained. According to the target frequency, the time interval can be divided into multiple small intervals, and different operating duty cycles can be set in each interval. It can be understood that configuring multiple different operating duty cycles corresponding to each other in multiple time intervals can enable the atomizing sheet to always operate at the target frequency, thereby achieving refined control of the atomizing sheet.

[0056] In an embodiment of the present invention, controlling the atomizing sheet to operate in multiple operating duty cycles at different times includes: controlling the atomizing sheet to operate in each time interval according to the corresponding operating duty cycle in that interval.

[0057] Specifically, according to the target frequency, after dividing the time interval into multiple small intervals and setting different operating duty cycles in each time interval, the atomizing sheet can be controlled to operate in each time interval according to the corresponding operating duty cycle in that interval, so that the atomizing sheet operates at different powers and atomization amounts in different time intervals. That is, in each time period, the working state of the atomizing sheet will be adjusted according to the operating duty cycle corresponding to that time period. It can be understood that by controlling the atomizing sheet to operate in multiple operating duty cycles at different times, the atomizing effect of the atomizing sheet can always be in the best state, avoiding situations where the atomization amount of the atomizer does not increase, does not decrease, does not atomize, or the human eye cannot distinguish the size of the fog state under different duty cycles after adjusting the duty cycle, thereby improving the atomizing effect.

[0058] In an embodiment of the present invention, the sum of the times of multiple time intervals is equal to the set time period, and the time length of each time interval is greater than the set unit time period and the time length of each time interval is a multiple of the unit time period, where the unit time period is obtained by evenly dividing the set time period into multiple time periods.

[0059] Specifically, the sum of the time lengths of all time intervals is equal to the set time period T. The set time period T can be evenly divided into multiple time periods, for example, N. Each time period is the unit time period t, and the time length of each time interval is greater than the set unit time period and the time length of each time interval is a multiple of the unit time period. For example, if the set time period T is 10 unit time periods, then the 10 unit time periods can be evenly divided into 5 time intervals, such as t1, t2........t5. The time length of each time interval is 2 unit time periods. At this time, the sum of the time lengths of all time intervals is equal to 10 unit time periods, that is, t1 + t2 +...... + t5 = T, 0 < t < t1, t2........t5, t(x) < T, and t1, t2........t(x - 1), t(x) are all multiples of t.

[0060] In a specific embodiment, the time intervals t1, t2, t3, ..., t(x) can be determined according to actual needs, and there is no limit to how many unit time intervals t are included in the time period T. It can be set according to the actual situation, and the time period T < 10 min.

[0061] In one embodiment of the present invention, the values ​​of multiple operating duty cycles decrease sequentially according to the sorting of multiple time intervals, and the value of the first operating duty cycle configured in the first time interval is less than the reciprocal of the target frequency.

[0062] Specifically, when the atomizer successfully tracks the frequency, its optimal frequency fk0, i.e., the target frequency, can be obtained. Based on the target frequency, the atomizer's duty cycle can be set to p1, with p1 within the time interval t1. Next, the duty cycle is set to p2, with p2 within the time interval t2, and so on. Finally, the duty cycle is set to p(x), with p(x) within the interval t(x). When setting multiple duty cycles p, they can be sequentially decreased according to the order of the multiple time intervals. Furthermore, the value of the first duty cycle configured within the first time interval is less than the reciprocal of the target frequency, i.e., 0. <p(x)<p(x-1)....p2<p1<1 / fk0。

[0063] In one embodiment of the present invention, the absolute value of the difference between two adjacent operating duty cycles does not exceed a preset difference.

[0064] Specifically, the absolute value of the difference between two adjacent operating duty cycles does not exceed a preset difference. That is, within any two adjacent time intervals, the absolute value of the difference between the operating duty cycles of the configured atomizing plate cannot exceed the preset difference. For example, if the preset difference is 0.1, then the absolute value of the difference between any two adjacent operating duty cycles cannot exceed 0.1. This ensures that the operating changes of the atomizing plate within adjacent time intervals can present a smooth trend, making the operation of the atomizing plate more stable and continuous in each time interval. This avoids excessive noise caused by excessive peak voltage jumps at both ends of the atomizing plate due to sudden changes in the operating duty cycle, thereby improving the user's comfort and experience.

[0065] In one embodiment of the present invention, the preset difference is a preset percentage of the current operating duty cycle of the atomizing plate.

[0066] Specifically, the preset difference is equal to a certain percentage of the current duty cycle of the atomizer. It controls the change in duty cycle between two adjacent time intervals. By setting the preset difference to a preset percentage of the current duty cycle, it ensures that the change in duty cycle between adjacent time intervals will not exceed this preset percentage. For example, assuming the current duty cycle of the atomizer is 0.1 and the preset difference is 20%, then the absolute value of the difference between the duty cycles between two adjacent time intervals cannot exceed 20% of 0.1, i.e., cannot exceed 0.02. This avoids excessive noise caused by large peak voltage jumps across the atomizer due to sudden changes in duty cycle, thus improving user comfort and experience.

[0067] In one embodiment of the present invention, the preset percentage includes 2%-5%.

[0068] Specifically, the preset percentage can be 2%-5%, that is, the preset difference can be 2%-5% of the current operating duty cycle. This can be understood as the change in the operating duty cycle between two adjacent time intervals not exceeding 2%-5% of the current operating duty cycle.

[0069] As a specific embodiment, the following is combined with Figure 3 The overall driving process of the atomizing plate driving method of the present invention will be illustrated by example.

[0070] In this embodiment, as Figure 3 As shown, the atomizing plate driving method mainly includes the following steps:

[0071] Step S11: Simulate the set time period T using a timer, and divide the set time period T into N unit time periods t, i.e., t = T / N.

[0072] Step S12: The atomizer is turned on and started.

[0073] Step S13: Start frequency tracking.

[0074] Step S14: Determine whether the frequency has been tracked to the optimal frequency fk0. If yes, proceed to step S15; otherwise, proceed to step S13.

[0075] Step S15: Based on fk0, set the operating duty cycle of the atomizing plate to p1, and the operating duty cycle p1 is within the time interval t1.

[0076] Step S16: Set the operating duty cycle of the atomizing plate to p2, and the operating duty cycle p2 is within the time interval t2.

[0077] Step S17: Set the operating duty cycle of the atomizing plate to p(x), and the operating duty cycle p(x) of the atomizing plate is in the interval t(x).

[0078] Step S18: The atomizer produces mist at the operating duty cycle set within the divided time interval.

[0079] Step S19: Determine whether fog is generated cyclically. If yes, proceed to step S15; otherwise, proceed to step S20.

[0080] Step S20: Turn off the atomizer and stop mist output.

[0081] In summary, the aforementioned atomizer driving method can track the frequency of the atomizer when it receives a power-on command. Based on the frequency tracking results, multiple operating duty cycles are configured for the atomizer, controlling it to execute different operating strategies at different times according to these duty cycles. This adjusts the atomization volume and avoids situations where the atomization volume doesn't increase, decrease, or even stop after adjusting the duty cycle, or where the human eye cannot distinguish the atomization size at different duty cycles, thus improving the atomization effect. Furthermore, by controlling the difference between adjacent duty cycles, excessive noise caused by large peak voltage jumps across the atomizer is avoided, improving user comfort and experience.

[0082] Figure 4 This is a schematic diagram of the structure of an atomizing plate driving device 10 according to an embodiment of the present invention. Figure 4 As shown, the atomizing plate driving device 10 includes: a processing module 20, a judgment module 30, a configuration module 40, and a control module 50.

[0096] The hair dryer device 10 according to an embodiment of the present invention can track the frequency of the atomizing plate when the atomizer receives a power-on command. Based on the frequency tracking result of the atomizing plate, multiple operating duty cycles are configured for the atomizing plate. The atomizing plate is controlled to execute different operating strategies according to the multiple operating duty cycles at different time periods, thereby adjusting the atomization volume. This avoids situations where the atomization volume of the atomizer does not increase, does not decrease, or does not produce mist after adjusting the duty cycle, or where the human eye cannot distinguish the mist size under different duty cycles, thus improving the atomization effect.

[0101] According to embodiments of the present invention, when the atomizer receives a power-on command, it can track the frequency of the atomizing plate. Based on the frequency tracking result, multiple operating duty cycles are configured for the atomizing plate. The atomizing plate is controlled to execute different operating strategies according to these multiple duty cycles at different times, thereby adjusting the atomization volume. This avoids situations where the atomization volume does not increase, decrease, or produce any mist after adjusting the duty cycle, or where the human eye cannot distinguish the mist size under different duty cycles, thus improving the atomization effect. Furthermore, by controlling the difference between adjacent duty cycles, excessive noise caused by large peak voltage jumps across the atomizing plate is avoided, improving user comfort and experience.

[0102] A further embodiment of the present invention discloses a computer-readable storage medium storing an atomizing plate driver program, which, when executed by a processor, implements the atomizing plate driving method as described in the first aspect embodiment of the present invention.

[0103] According to an embodiment of the present invention, when the atomizer driver stored thereon is executed by a processor, it can perform frequency tracking on the atomizer when the atomizer receives a power-on command. Based on the frequency tracking result, multiple operating duty cycles are configured for the atomizer, and the atomizer is controlled to execute different operating strategies according to the multiple operating duty cycles at different time periods, thereby adjusting the atomization volume. This avoids situations where the atomization volume of the atomizer does not increase, does not decrease, or does not produce any mist after adjusting the duty cycle, and prevents the human eye from being unable to distinguish the mist size under different duty cycles, thus improving the atomization effect. Furthermore, by controlling the difference between adjacent duty cycles, excessive noise caused by excessive peak voltage jumps at both ends of the atomizer is avoided, improving the user's comfort and experience.
