Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
Referring to fig. 1, a schematic structural diagram of a first embodiment of an atomization device according to the present application is shown, and specifically, the atomization device includes an atomization sheet 11 and an atomization control circuit 12, wherein the atomization sheet 11 is used for atomizing a substrate to be atomized under the control of the atomization control circuit 12, and the substrate to be atomized is a liquid.
Specifically, the atomizing control circuit 12 is connected with the atomizing sheet 11, and when the atomizing device is powered on, the atomizing control circuit 12 outputs a first constant power P1 to drive the atomizing sheet 11 so as to detect whether the atomizing sheet 11 has a substrate to be atomized or not, and when detecting that the atomizing sheet 11 has the substrate to be atomized, outputs a second constant power P2 to drive the atomizing sheet 11 to atomize the substrate to be atomized. In one embodiment, the first constant power P1 is smaller than the second constant power P2, and the first constant power P1 is insufficient power to atomize the substrate to be atomized, so as to prevent the dry burning of the atomizing sheet 11 when atomizing the substrate to be atomized.
Further, the atomization control circuit 12 includes: a power supply 121 and a control chip 122. Wherein, the power supply 121 is used for providing a driving current I and a driving voltage V; the control chip 122 is connected to the power supply 121, and is configured to detect the driving current I and the driving voltage V in real time, and output the first constant power P1 or the second constant power P2 according to the driving current I and the driving voltage V to drive the atomizing sheet 11. Specifically, after the atomizing device is powered on, the control chip 122 detects the driving current I and the driving voltage V provided by the power supply 121 in real time, calculates the driving power output by the current power supply 121 according to the driving current I and the driving voltage V, determines whether the driving power reaches the first constant power P1, if the driving power does not reach the first constant power P1, the control chip 122 outputs a first PWM signal, adjusts the duty ratio of the first PWM signal, so as to adjust the driving power output by the power supply 121 to the first constant power P1, and drives the atomizing sheet 11 by using the first constant power P1. After the atomizing sheet 11 is driven by the first constant power P1, if the driving current I is detected to be greater than the first preset current value Im1, the control chip 122 adjusts the duty ratio of the first PWM signal, and adjusts the first constant power P1 to be the second constant power P2, so that the power output by the power supply 121 is the second constant power P2, so as to drive the atomizing sheet 11 to atomize the substrate to be atomized by using the second constant power P2. Specifically, the control chip 122 outputs the first constant power P1 to drive the atomizing sheet 11, at this time, if the atomizing sheet 11 has a substrate to be atomized, the substrate to be atomized will act as a load to further influence the current passing through the atomizing sheet 11, so that the driving current I provided by the power supply 121 is increased, the control chip 122 detects the driving current I provided by the power supply 121, and when the driving current I is detected to be greater than the first preset current value Im1, the atomizing sheet 11 has the substrate to be atomized, and at this time, the control chip 122 outputs the second constant power P2 to drive the atomizing sheet 11 to start atomizing the substrate to be atomized. This can prevent dry burning of the atomizing sheet 11.
Specifically, when the atomizing sheet 11 is driven to atomize the substrate to be atomized by the second constant power P2, the driving current I is continuously detected, and if the driving current I is detected to be smaller than the second preset current value Im2, the atomization of the substrate to be atomized is ended. Specifically, the control chip 122 continuously detects the driving current I, when the substrate to be atomized on the atomizing sheet 11 is atomized, the load on the atomizing sheet 11 disappears, the driving current I provided by the power supply 121 decreases, and at this time, if the control chip 122 detects that the driving current I is smaller than the second preset current value Im2, it indicates that the substrate to be atomized is atomized.
The atomization control circuit 12 further includes: current sampling circuit 123 and voltage sampling circuit 124. The current sampling circuit 123 is connected to the power supply 121 and the control chip 122, and is configured to sample a driving current I provided by the power supply 121 and transmit the driving current I to the control chip 122. The voltage sampling circuit 124 is connected to the power supply 121 and the control chip 122, samples the driving voltage V provided by the power supply 121, and transmits the driving voltage V to the control chip 122.
Specifically, when the atomizing device is driven at the first constant power P1, the current sampling circuit 123 samples a plurality of driving currents I and calculates an average value thereof to obtain a reference current value I0, and if the driving current I sampled by the current sampling circuit 123 is greater than the sum of the reference current value I0 and the first set current value I1 (i.e., the first preset current value Im 1), it is determined that the atomizing sheet 11 has a substrate to be atomized. When the atomizing device is driven with the second constant power P2, if the driving current I sampled by the current sampling circuit 123 is smaller than the sum of the reference current value I0 and the second set current value I2 (i.e., the second preset current value Im 2), it is determined that the atomization of the substrate to be atomized is completed, wherein the second set current value I2 is greater than the first set current value I1.
In this embodiment, the atomization control circuit 12 further includes: the adjusting circuit 125, the adjusting circuit 125 is connected to the current sampling circuit 123, the control chip 122 and the atomizing sheet 11, receives the first PWM signal, and outputs the operating voltage V1 according to the first PWM signal to drive the atomizing sheet 11. Specifically, after the atomizing device is powered on, the current sampling circuit 123 and the voltage sampling circuit 124 sample the driving current I and the driving voltage V provided by the power supply 121 in real time, and transmit the sampled driving current I and driving voltage V to the control chip 122, the control chip 122 calculates driving power according to the driving current I and the driving voltage V, determines whether the driving power reaches the first constant power P1, if the calculated driving power does not reach the first constant power P1, the control chip 122 adjusts the duty ratio of the first PWM signal output to the adjusting circuit 125 by using the PID control algorithm, and the adjusting circuit 125 outputs the working voltage V1 according to the first PWM signal, so that the working voltage V1 is equal to the first voltage value, and then drives the atomizing sheet 11, and at this time, the power output by the power supply 121 is the first constant power P1. The atomizing sheet 11 has a substrate to be atomized, the driving current I sampled by the current sampling circuit 123 is greater than the first preset current value Im1, the control chip 122 continuously adjusts the duty ratio of the first PWM signal output to the adjusting circuit 125 by using the PID control algorithm, and the adjusting circuit 125 outputs the working voltage V1 according to the first PWM signal, so that the working voltage V1 is equal to the second voltage value to drive the atomizing sheet 11, and at this time, the power output by the power supply 121 is the second constant power P2. It can be appreciated that by adjusting the duty cycle of the first PWM signal, the operating voltage V1 output by the adjusting circuit 125 can be changed, so that the power supply 121 drives the atomizing sheet 11 with the first constant power P1 or the second constant power P2. Specifically, when the control chip 122 outputs the first PWM signals with different duty ratios, the operating voltage V1 output by the adjusting circuit 125 is different, and thus, the driving power for driving the atomizing sheet 11 is also different. According to the technical solution of the present embodiment, when the power output by the power supply 121 does not reach the first constant power P1, the control chip 11 adjusts the duty ratio of the first PWM signal, and the adjusting circuit 125 outputs the operating voltage V1 having the first voltage value to drive the atomizing sheet 11, where the power output by the power supply 121 is the first constant power P1; when it is detected that the atomizing sheet 11 has a substrate to be atomized, the control chip 11 adjusts the duty ratio of the first PWM signal, and the adjusting circuit 125 outputs the operating voltage V1 having the second voltage value to drive the atomizing sheet 11, and at this time, the power output by the power supply 121 is the second constant power P2.
The adjusting circuit 125 includes an adjustable voltage boosting circuit 1251 and an analog-to-digital conversion circuit 1252, the analog-to-digital conversion circuit 1252 is connected to the control chip 122, and the adjustable voltage boosting circuit 1251 is connected to the analog-to-digital conversion circuit 1252 and the current sampling circuit 123. The analog-to-digital conversion circuit 1252 receives the first PWM signal, and the adjustable boost circuit 1251 generates an operating voltage V1 to drive the atomizing plate 11 according to the first PWM signal.
In this embodiment, the atomization control circuit 12 further includes: the driving circuit 126, the driving circuit 126 is connected to the control chip 122, the adjusting circuit 125 and the atomizing sheet 11, and specifically, the driving circuit 126 is connected to the control chip 122, the adjustable booster circuit 1251 of the adjusting circuit 125 and the atomizing sheet 11. The control chip 122 outputs a second PWM signal to control the driving circuit 126 to drive the atomizing sheet 11 to vibrate, and the driving circuit 126 atomizes the substrate to be atomized based on the second PWM signal output by the control chip 122 and the working voltage V1 output by the adjusting circuit 125. Specifically, the driving circuit 126 generates the output voltage V2 based on the second PWM signal output by the control chip 122 and the working voltage V1 output by the adjusting circuit 125 to drive the atomizing sheet 11 to atomize the substrate to be atomized, wherein the larger the working voltage V1, the larger the output voltage V2, and the larger the atomization amount. The operating voltage V1 output from the adjustable booster circuit 1251 can control the atomization amount of the atomizing sheet 11. That is, when the second constant power P2 is used for driving, the atomization amount can be adjusted according to the operating voltage V1 output by the adjusting circuit 125, different driving powers correspond to different atomization amounts, and the power for atomization can be further adjusted according to the required atomization amount.
According to the atomization device, the atomization sheet 11 can work under two different constant power states, whether the atomization sheet 11 is provided with the matrix to be atomized or not is detected when the first constant power P1 is provided with the matrix to be atomized, and if the atomization sheet 11 is provided with the matrix to be atomized, the second constant power P2 is adopted for atomization, wherein the first constant power P1 is insufficient power for enabling the matrix to be atomized, so that dry burning of the atomization sheet 11 can be avoided.
The first constant power P1 and the second constant power P2 in the embodiment may be calculated powers of the driving current I and the driving voltage V output by the power supply 121, or may be calculated powers of the working voltage V1 and the current output by the adjustable booster circuit 1251 in the adjusting circuit 125. Alternatively, in another embodiment, the first constant power P1 and the second constant power P2 may be calculated powers of the voltage V2 and the current of the driving atomizing plate 11 output by the driving circuit, which is not limited specifically.
The atomizing device shown in fig. 1 can be applied to a case where the current variation is large, for example, when the current variation reaches several hundred milliamperes, the current sampling circuit 123 can directly sample the current. When the current change is small, for example, the current change is only tens of milliamperes, the sampling accuracy is affected. Thus, in order to improve the current sampling accuracy, in one embodiment, the adjusting circuit 125 is connected in front of the current sampling circuit 123, as shown in fig. 2.

Specifically, after the atomizing device is electrified, the atomizing sheet of the atomizing device is driven by the first constant power, and whether the atomizing sheet is provided with a matrix to be atomized or not is detected. The first constant power is a power insufficient to atomize the substrate to be atomized, whereby dry burning can be prevented from occurring at the first constant power.
In a specific embodiment, after the atomizing device is powered on, the driving current and the driving voltage provided by the power supply are collected, the current driving power is calculated, and if the current driving power does not reach the first constant power P1, the duty ratio of the first PWM signal is adjusted by using the PID control algorithm, so that the current driving power reaches the first constant power P1, and then the atomizing sheet of the atomizing device is driven. When the first constant power P1 is used for driving the atomizing sheet, continuously collecting driving current provided by a power supply, and if the driving current is larger than a first preset current value Im1, the atomizing sheet is provided with a matrix to be atomized. Specifically, if the atomizing sheet has a substrate to be atomized, the substrate to be atomized is used as a load, so that the driving current provided by the power supply is increased.
Step S52: if the atomizing sheet is provided with the matrix to be atomized, the second constant power is utilized to drive the atomizing sheet to atomize the matrix to be atomized.
Specifically, if the atomizing sheet is provided with a substrate to be atomized, the duty ratio of the first PWM signal is adjusted by utilizing a PID control algorithm so as to adjust the first constant power into the second constant power, and the atomizing sheet of the atomizing device is driven by utilizing the second constant power P2 so as to atomize the substrate to be atomized.
According to the application method of the atomizing device, the atomizing sheet can work in two different constant power states, whether the atomizing sheet is provided with the matrix to be atomized or not is detected when the first constant power is provided with the matrix to be atomized, and if the atomizing sheet is provided with the matrix to be atomized, the second constant power is adopted for atomizing, wherein the first constant power is insufficient power for enabling the matrix to be atomized, so that dry burning of the atomizing sheet can be avoided.
