[0055] In order to make the purpose, technical scheme and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not to limit the present application.

[0056] In one embodiment, as shown in Figure 1 a method for measuring resistance of an atomizer is provided, comprising the following steps:

[0057] Step 100, reading the resistance of the atomizer every first preset time, obtaining a first preset number of first resistances.

[0058] The method described in the present application can be applied to electronic atomization equipment, and can also be applied to other equipment for measuring the resistance of an atomizer.

[0059] Specifically, when measuring the resistance of an atomizer, the atomizer can be connected to the electronic atomization equipment or other measuring equipment. Then the resistance of the atomizer is read every first preset time, and a corresponding first preset number of resistances is obtained. For the convenience of description, the resistance obtained in this step is defined as the first resistance. The first preset time can be any time within 0.1-1 seconds, for example, the resistance of the atomizer is read every 0.5 seconds. In order to ensure the accuracy of the results, the first preset number is a natural number greater than or equal to 2.

[0060] Step 110, starting the atomizer for a second preset time.

[0061] The atomizer is started and works normally for a second preset time. The second preset time can be any time within 0.3-1 seconds. Because the second preset time is short, the resistance of the atomizer changes little in the normal state (the atomizer is set in the atomization liquid and works normally). In specific implementation, the second preset time can be other time. It can be understood that the second preset time should not be too long. If the atomizer is started for too long, the temperature of the atomizer will be relatively high, and the resistance measurement process of the atomizer needs to be re-executed after waiting for the atomizer to cool down. In the present application, the second preset time for starting the atomizer can change the state of the atomizer, confirm whether the TCR of the atomizer is normal, and lay a foundation for subsequent accurate measurement.

[0062] Step 120, reading the resistance of the atomizer every third preset time, obtaining a second preset number of second resistances.

[0063] After the atomizer works for a second preset time, the resistance of the atomizer is read every third preset time, and a corresponding second preset number of resistances is obtained. For the convenience of description, the resistance obtained in this step is defined as the second resistance. The third preset time can be the same as or different from the first preset time, which is not limited here. Similarly, the second preset number and the first preset number can be the same or different in specific implementation, which is not limited here.

[0064] It can be understood that the first preset number and the second preset number can also be 1. If the first preset number and the second preset number are both 1, the accuracy of the result will be lower, but the accuracy is still improved compared with the prior art method (directly reading the resistance value of the atomizer as the initial resistance value of the atomizer when the atomizer is connected).

[0065] Step 130, calculating the average of the first resistance value and the second resistance value as the initial resistance value of the atomizer.

[0066] After obtaining a plurality of first resistance values and a plurality of second resistance values, the average of the plurality of first resistance values and the plurality of second resistance values is calculated, and the calculated average is taken as the initial resistance value of the atomizer.

[0067] The resistance measurement method of the atomizer, by reading the resistance value of the atomizer every first preset time, obtains a first preset number of first resistance values; the atomizer is started for a second preset time; the resistance value of the atomizer is read every third preset time, and a second preset number of second resistance values are obtained; the average of the first resistance value and the second resistance value is calculated as the initial resistance value of the atomizer. In this way, the first resistance value of the atomizer is obtained multiple times, the atomizer is started for a second preset time, the second resistance value of the atomizer is obtained multiple times, and finally the average of a plurality of first resistance values and a plurality of second resistance values is calculated as the initial resistance value of the atomizer. The method of reading the resistance value multiple times and then taking the average ensures the accuracy of the result, and avoids the contact resistance generated when the atomizer is connected, thereby improving the initial resistance value measurement accuracy of the atomizer.

[0068] In one embodiment, as shown in Figure 2 The resistance measurement method of the atomizer further comprises:

[0069] Step 140, determining the fluctuation range of the first resistance value.

[0070] If the fluctuation range of the first resistance value is within the preset fluctuation range, step 110 is performed: starting the atomizer for a second preset time.

[0071] Step 150, determining that the state of the atomizer is abnormal, and generating corresponding alarm information.

[0072] As an embodiment, in order to improve the accuracy of the resistance result measurement, after obtaining a plurality of first resistances, the fluctuation range of the first resistance is determined according to the obtained plurality of first resistances. If the fluctuation range of the first resistance is within the preset fluctuation range, it is considered that the state of the atomizer is normal, and step 110 is continued to be executed. If the fluctuation range of the first resistance is not within the preset fluctuation range, it is determined that the state of the atomizer is abnormal (the abnormal state includes dry burning of the atomizer, TCR out-of-range, etc.). If the state of the atomizer is abnormal, the obtained resistance value must also have a problem. At this time, corresponding alarm information is generated, and the electronic atomization equipment can display the abnormal state display light according to the alarm information to remind the user or display the alarm information on the display screen in the electronic atomization equipment to remind the user. As an example, the preset fluctuation range is [-10%, 10%]. After considering that the state of the atomizer is abnormal, a period of time (for example, 30-60 seconds) can be waited, and then the step is re-executed, that is, the resistance value of the atomizer is read every first preset time, and a plurality of first resistance values are re-acquired.

[0073] As an embodiment, the step of determining the fluctuation range of the first resistance value comprises:

[0074] The difference between adjacent first resistance values is calculated to obtain a plurality of difference values.

[0075] The fluctuation range of the first resistance value is calculated according to the plurality of difference values.

[0076] Specifically, in the embodiment, the process of determining the fluctuation range of the first resistance value comprises calculating the difference between adjacent first resistance values to obtain a plurality of difference values, and then calculating the fluctuation range of the first resistance value according to the obtained plurality of difference values. It should be noted that the number of first resistance values in the embodiment is a natural number greater than or equal to 3. When the number of first resistance values is greater than or equal to 3, a plurality of difference values can be obtained. For example, the number of first resistance values is 4, which are R1, R2, R3, and R4 respectively. R2-R1=R 21 , R3-R2=R 32 , and R4-R3=R 43 Then, the fluctuation range of the first resistance value is calculated according to R 21 , R 32 , and R 43 The fluctuation of the first resistance value can be calculated by the following formula: R 21 / R1, R 32 / R2, and R 43 / R3. The fluctuation range of the first resistance value is determined according to the calculated fluctuation. For example, R 21 / R1=5%, R 32 / R2=-5%, and R 43R3=6%, the fluctuation range of the first resistance value is [-5%, 6%]. In a specific implementation, the fluctuation range of the first resistance value can also be determined in other manners. For example, the plurality of difference values obtained through calculation are formed into a chart, the fluctuation range of the first resistance value is determined through the chart, and whether the fluctuation range of the first resistance value is in the preset range is determined again.

[0077] In one embodiment, as shown in FIG. 1, the resistance measurement method of the atomizer further includes: Figure 3

[0078] Step 160, reading the resistance value of the atomizer to obtain a third resistance.

[0079] If the third resistance is in the preset resistance range, step 120 is performed: the resistance value of the atomizer is read every third preset time to obtain a second preset number of second resistance values.

[0080] Step 170, generating corresponding alarm information.

[0081] Specifically, in the embodiment, after the atomizer is started, the resistance value of the atomizer is read before the second resistance value of the atomizer is obtained, and the resistance of the atomizer after working for a second preset time is obtained, which is defined as a third resistance. After the third resistance of the atomizer is obtained, it is determined whether the third resistance is in the preset resistance range. Generally, because the working time of the atomizer is short, if the atomizer is normally immersed in oil (atomization liquid) and can work normally, the resistance value of the atomizer changes little (for example, the resistance of the atomizer changes by 20-50 milliohms when the atomizer works for 0.3-1 second). Therefore, only the preset resistance range of the atomizer needs to be set according to experience, and then it is determined whether the third resistance obtained is in the preset resistance range, so as to determine whether the atomizer can work normally. For example, the preset resistance range is [0.5Ω, 2Ω]. If the third resistance is in the preset resistance range, step 120 is performed: the resistance value of the atomizer is read every third preset time to obtain a second preset number of second resistance values. If the third resistance is not in the preset resistance range, it indicates that the atomizer cannot work normally (for example, an abnormal working state of the atomizer caused by dry burning due to the absence of atomization liquid), and corresponding alarm information is generated at this time to prompt the user and exit the initial resistance measurement process of the atomizer.

[0082] ​It should be noted that the alarm information generated by step 170 and step 150 can be the same or different. For example, if the electronic atomization device uses an indicator light to display the alarm information, the alarm information generated by step 170 and step 150 is the same. If the electronic atomization device uses a display screen to display the alarm information, the alarm information generated by step 170 and step 150 can be different, so that the user can distinguish the specific situation of the alarm. For example, the alarm information generated by step 170 is that the atomizer resistance changes too much after the atomizer works for 1 second; the alarm information generated by step 150 is that the value of the atomizer fluctuates greatly after the atomizer is connected. It can be understood that if the electronic atomization device uses an indicator light to display the alarm information, the alarm information generated by step 170 and step 150 can also be different. Different alarm information, different indicator light display frequency / color.

[0083] In one embodiment, as shown in Figure 4 the resistance measurement method of the atomizer further comprises:

[0084] Step 180, determining the average value of the first resistance value and the average value of the second resistance value;

[0085] If the difference between the average value of the first resistance value and the average value of the second resistance value is within the preset difference range, step 130 is executed: the average value of the first resistance value and the second resistance value is calculated as the initial resistance value of the atomizer;

[0086] Step 190, generating corresponding alarm information.

[0087] Specifically, in the present embodiment, after obtaining a plurality of second resistance values, the average value of the first resistance value and the average value of the second resistance value are calculated, the difference range of the two is determined according to the average value of the first resistance value and the average value of the second resistance value, and then whether the difference range of the two is within the preset difference range is determined to determine whether the atomizer is reliably contacted. If the difference range of the two is within the preset difference range, it means that the atomizer is reliably contacted, and step 130 is executed: the average value of the first resistance value and the second resistance value is calculated as the initial resistance value of the atomizer. If the difference range of the two is not within the preset difference range, it means that the atomizer is not reliably contacted, and corresponding alarm information is generated at this time. Wherein the difference range of the two is determined according to the average value of the first resistance value and the average value of the second resistance value, which can specifically include: calculating the difference value of the average value of the first resistance value and the average value of the second resistance value, and then calculating the ratio of the difference value to the average value of the first resistance value. The ratio is compared with the preset difference range. For example, the preset difference range is [-10%, 10%].

[0088] It should be noted that the alarm information generated by step 190 and step 150 can be the same or different. For example, if the electronic atomization device uses an indicator light to display the alarm information, the alarm information generated by step 190 and step 150 is the same. If the electronic atomization device uses a display screen to display the alarm information, the alarm information generated by step 190 and step 150 can be different, so that the user can distinguish the specific situation of the alarm. For example, the alarm information generated by step 190 is that the atomizer contact is unreliable; the alarm information generated by step 150 is that after connecting the atomizer, the value of the atomizer fluctuates greatly. It can be understood that if the electronic atomization device uses an indicator light to display the alarm information, the alarm information generated by step 190 and step 150 can also be different. Different alarm information, different indicator light display frequency / color.

[0089] In one embodiment, as shown in Figure 5 the resistance measurement method of the atomizer further comprises:

[0090] Step 200, detecting the port level of the processor in the electronic atomization device to which the atomizer belongs;

[0091] If the port level of the processor is detected to drop, step 100 is performed: the resistance value of the atomizer is read every first preset time to obtain a first preset number of first resistance values.

[0092] Specifically, before the above-mentioned starting of the atomizer resistance measurement process, as an embodiment, the present application further detects the port level of the processor in the electronic atomization device to which the atomizer belongs. If the port level of the processor appears a falling edge, it indicates that the atomizer is connected, at which time the processor is woken up or triggered to start the atomizer resistance measurement process, i.e., step 100 is started to be executed. In a specific implementation, the processor can also be triggered to start the atomizer resistance measurement process by a physical button (for example, a reset button / power button) in the electronic atomization device.

[0093] In one embodiment, as shown in Figure 6 the resistance measurement method of the atomizer further comprises:

[0094] Step 210, obtaining the current environmental temperature through an environmental temperature sensor;

[0095] Step 220, setting the temperature parameter in the reference temperature resistance value parameter of the atomizer to the current environmental temperature.

[0096] Specifically, the above steps achieve the measurement of the resistance value of the atomizer to derive the temperature at which the atomizer is located according to the temperature coefficient of resistance, so as to facilitate the control of the electronic atomization device. However, the initial temperature of the atomizer is usually set as room temperature (25°) in the prior art, but the electronic atomization device can be located at any position in the world, that is, the ambient temperature at which the atomizer is located can be -30°, -10°, 0°, 40°, etc. Obviously, setting the initial temperature of the atomizer as 25° is not conducive to the control of the electronic atomization device. Therefore, in the embodiment, after the measurement of the resistance of the atomizer is completed, that is, after the initial resistance value of the atomizer is obtained, the current ambient temperature is acquired by the ambient temperature sensor arranged in the electronic atomization device as the initial temperature, and the calibration of the parameters in the TCR is completed.

[0097] In one embodiment, the resistance measurement method of the atomizer can include detecting the port level of the processor in the electronic atomization device, detecting a falling edge of the port level of the processor to indicate that the atomizer is connected, and waking up or triggering the processor to start the measurement process of the resistance of the atomizer.

[0098] The resistance value of the atomizer is read every first preset time to obtain a plurality of first resistance values, the fluctuation range of the plurality of first resistance values is determined, and if the fluctuation range of the plurality of first resistance values is within a preset fluctuation range, it is determined that the atomizer is connected normally.

[0099] After determining that the atomizer is in a normal state, the atomizer is started to work normally for a second preset time, and then the resistance value of the atomizer is read. If the resistance value of the atomizer is within a preset resistance value range at this time, it is determined that the TCR of the atomizer is normal. If the resistance value of the atomizer is not within the preset resistance value range, it is determined that the TCR can be out of range, or the atomizer liquid can be insufficient, or the atomizer can be dry, etc. An alarm is given and the current identification state is exited.

[0100] After determining that the TCR of the atomizer is normal, the resistance of the atomizer is read every third preset time to obtain a second preset number of second resistance values (it can be understood that the third preset time can be the same as the first preset time, and the second preset number can be the same as the first preset number). Then, the average of the second resistance values and the average of the first resistance values are compared. If the difference between the two is within a preset difference range, the average of the second resistance values and the average of the first resistance values are calculated again to obtain the measurement result, that is, the average of all the first resistance values and the second resistance values is taken to obtain the initial resistance value of the atomizer.

[0101] After obtaining the initial resistance value of the atomizer, the current ambient temperature is acquired as the initial temperature, and the parameters in the TCR are calibrated according to the initial resistance value and the initial temperature. After the calibration is completed, the atomizer can be used normally. The resistance value of the atomizer after the above process is as follows: Figure 7As shown, when the atomizer is accessed, the resistance value is maximum, and then gradually decreases, and in the second preset time when the atomizer is started to work normally, the resistance value of the atomizer becomes large (i.e. the heating section in the figure), the atomizer normal work ends (heating ends), and under normal circumstances, the resistance of the atomizer becomes small again. Therefore, before and after heating, the first resistance value and the second resistance value are obtained multiple times, and then the average value of the two is obtained, so that the resistance value closer to the real resistance of the atomizer can be obtained as the initial value.

[0102] TCR = dR / R*dT = (R i -R0) / R0*(T i -T0), R i represents the current resistance value of the atomizer, R0 represents the initial resistance value of the atomizer, T i represents the current temperature of the electronic atomization device, T0 represents the initial temperature of the atomizer. In the normal use process, the current resistance value R i of the atomizer can be read, and R0, T0 and TCR are known, so that the current temperature T i of the atomizer can be calculated, and the temperature control of the electronic atomization device is facilitated.
