[0041] See also Figure 1 , Figure 1 1 is a flow chart of a voltage detection method for an electronic atomization device provided in an embodiment of the present application. The voltage detection method for the electronic atomization device includes:

[0042] S11. When the electronic atomization device is subjected to voltage detection through an external DC power supply, a no-load voltage difference and a loaded voltage difference between the external DC power supply and the battery of the electronic atomization device are obtained, wherein the no-load voltage difference is used to characterize the voltage difference caused by the impedance generated when the external DC power supply is connected to the battery; the loaded voltage difference is used to characterize the voltage difference between the battery and the external DC power supply when the battery is being charged;

[0043] S12, determining an output voltage value when the external DC power supply charges the battery according to the preset screening voltage value, the no-load voltage difference value and the loaded voltage difference value;

[0044] S13, charging the battery of the electronic atomization device according to the output voltage value through an external DC power supply to obtain a battery display status of the electronic atomization device;

[0045] S14. Determine the battery voltage value range of the electronic atomization device according to the battery display status of the electronic atomization device.

[0046] It should be noted that this method is mainly used in the battery voltage detection process of electronic atomization equipment.

[0047] An external DC power supply is a power supply device that can provide a stable DC voltage to an electronic atomization device.

[0048] Specifically, first, obtain the no-load voltage difference and the loaded voltage difference between the external DC power supply and the electronic atomization device. The no-load voltage difference is the voltage difference caused by the certain impedance between the connected wire and the battery itself when the external DC power supply is connected to the battery of the electronic atomization device. The no-load voltage difference reflects the voltage loss caused by impedance when there is no load (that is, the battery has not started charging). When the battery starts charging, the battery consumes current as a load, which will cause a voltage difference between the output voltage of the external DC power supply and the voltage actually received by the battery. This voltage difference is the loaded voltage difference. The loaded voltage difference reflects the voltage loss between the battery and the external DC power supply caused by factors such as current flow and internal impedance of the battery during the charging process.

[0049] Secondly, through the preset screening voltage value, and the previously obtained no-load voltage difference and loaded voltage difference, the output voltage value that the external DC power supply should output during charging can be determined, so as to charge the battery of the electronic atomization device through the output voltage value. The preset screening voltage value is a pre-set safety voltage value for screening batteries.

[0050] Then, according to the determined output voltage value, the voltage of the external DC power supply is set to the output voltage value, and the battery of the electronic atomization device is charged, thereby obtaining the battery display status of the electronic atomization device. The battery display status can reflect the charging status of the battery, that is, whether it is rechargeable or not.

[0051] Furthermore, according to the battery display status of the electronic atomization device obtained above, the battery voltage value range of the electronic atomization device can be determined, that is, if the battery display status is rechargeable, it means that the battery can be charged at this time, which means that the battery voltage is less than the output voltage value, that is, the battery voltage value range is less than the preset screening voltage value; if the battery display status is non-rechargeable, it means that the battery is fully charged at this time, which means that the battery voltage is greater than or equal to the output voltage value, that is, the battery voltage value range is greater than or equal to the preset screening voltage value. That is, through the battery display status, the battery voltage of the electronic atomization device can be screened according to the preset screening voltage value.

[0052] It can be understood that the embodiment of the present application provides a voltage detection method for an electronic atomization device, the method comprising: when the voltage of the electronic atomization device is detected by an external DC power supply, the no-load voltage difference and the loaded voltage difference between the external DC power supply and the battery of the electronic atomization device are obtained, wherein the no-load voltage difference is used to characterize the voltage difference caused by the impedance generated when the external DC power supply is connected to the battery; the loaded voltage difference is used to characterize the voltage difference between the external DC power supply when the battery is charged; according to the preset screening voltage value, the no-load voltage difference and the loaded voltage difference, the output voltage value when the external DC power supply is charging the battery is determined; the battery of the electronic atomization device is charged by the external DC power supply according to the output voltage value, and the battery display status of the electronic atomization device is obtained; according to the battery display status of the electronic atomization device, the battery voltage value range of the electronic atomization device is determined. The method provided in the embodiment of the present application can solve the problem that the internal battery voltage of the existing electronic atomization device cannot be accurately detected without disassembling the device, thereby avoiding the related losses caused by the need to disassemble the device due to the inability to directly measure the voltage of the electronic atomization device.

[0053] In a possible implementation, obtaining a no-load voltage difference between an external DC power supply and a battery of an electronic atomization device includes:

[0054] Obtaining a no-load voltage difference according to a first power supply voltage value displayed by the external DC power supply obtained by connecting the external DC power supply to the battery to be tested and a first display voltage value displayed by the multimeter obtained by connecting the multimeter to the battery to be tested;

[0055] The battery to be tested is an internal battery of a sample of the electronic atomization device obtained by destroying the sample of the electronic atomization device.

[0056] It should be noted that when obtaining the no-load voltage difference, a sample of an electronic atomization device needs to be destroyed in advance to obtain its internal battery, which is the battery to be tested.

[0057] Specifically, an external DC power supply and a multimeter are connected to the battery to be tested, respectively, so as to obtain a first power supply voltage value measured by the external DC power supply and a first display voltage value measured by the multimeter; then, the no-load voltage difference is determined according to the first power supply voltage value and the first display voltage value. It should be understood that the no-load voltage difference is pre-measured and calculated before the battery voltage detection of the electronic atomization device is performed, which reflects the voltage loss caused by impedance when there is no load (i.e., the battery has not started to be charged).

[0058] In a possible implementation, obtaining the no-load voltage difference according to a first power supply voltage value displayed by an external DC power supply obtained by connecting the external DC power supply to the battery to be tested and a first display voltage value displayed by a multimeter obtained by connecting the multimeter to the battery to be tested includes:

[0059] By connecting the positive terminal of the external DC power supply to the positive connection port of the battery to be tested and the negative terminal of the external DC power supply to the negative connection port of the battery to be tested, a first power supply voltage value displayed by the external DC power supply is obtained;

[0060] By connecting the positive terminal of the multimeter to the positive connection port of the battery to be tested, and connecting the negative terminal of the multimeter to the negative connection port of the battery to be tested, a first display voltage value displayed by the multimeter is obtained;

[0061] The first power supply voltage value is subtracted from the first display voltage value to obtain a no-load voltage difference.

[0062] Specifically, the specific connection method of the external DC power supply, the multimeter and the battery to be tested is: the positive terminal of the external DC power supply is connected to the positive connection port of the battery to be tested, and the negative terminal of the external DC power supply is connected to the negative connection port of the battery to be tested; the positive terminal of the multimeter is connected to the positive connection port of the battery to be tested, and the negative terminal of the multimeter is connected to the negative connection port of the battery to be tested.

[0063] The first power supply voltage value displayed by the external DC power supply and the first display voltage value displayed by the multimeter are obtained through the above connection mode, and then the first display voltage value is subtracted from the first power supply voltage value to obtain the no-load voltage difference.

[0064] In a possible implementation, after obtaining the no-load voltage difference, obtaining the loaded voltage difference between the external DC power supply and the battery of the electronic atomization device includes:

[0065] The regulated current of the external DC power supply is set to a preset current value, and the voltage of the external DC power supply is increased so that the voltage of the battery to be tested rises until the battery to be tested indicates that it is chargeable, and a second power supply voltage value displayed by the external DC power supply and a second display voltage value displayed by the multimeter are obtained;

[0066] The second power supply voltage value is subtracted from the second display voltage value and the no-load voltage difference value to obtain the loaded voltage difference value.

[0067] It should be noted that after obtaining the no-load voltage difference through the above connection method, the regulating current of the external DC power supply is set to the preset current value, and the voltage of the external DC power supply is gradually increased while observing the voltage change of the battery to be tested. When the voltage of the battery to be tested rises to a state showing a rechargeable state, the second power supply voltage value displayed by the external DC power supply and the second display voltage value displayed by the multimeter are recorded. Then, the result obtained by subtracting the second power supply voltage value from the second display voltage value is subtracted from the no-load voltage difference calculated previously to obtain the loaded voltage difference. Among them, the preset current value should be determined according to the specifications and charging requirements of the battery to be tested to ensure that the battery is charged under safe conditions.

[0068] It should be understood that the loaded voltage difference is measured and calculated in advance before the battery voltage detection of the electronic atomization device is performed, which reflects the voltage loss between the battery and the external DC power supply caused by factors such as current flow and internal impedance of the battery during the charging process.

[0069] In a possible implementation, determining an output voltage value when an external DC power source charges a battery according to a preset screening voltage value, a no-load voltage difference value, and a loaded voltage difference value includes:

[0070] The preset screening voltage value is added to the no-load voltage difference, the loaded voltage difference, and the preset internal control voltage value to obtain the output voltage value.

[0071] It should be noted that the screened battery voltage range is the output voltage value set by the external DC power supply minus the no-load voltage difference, the loaded voltage difference and the preset internal control voltage value, that is, the output voltage value of the external DC power supply is obtained by adding the preset screening voltage value to the no-load voltage difference, the loaded voltage difference and the preset internal control voltage value. Among them, the preset internal control voltage value is a pre-set control voltage value used to ensure the stability and safety of the output voltage. It should be noted that in this embodiment, the specific value of the preset internal control voltage value is not limited and can be set according to actual conditions.

[0072] In actual applications, if the battery voltage value of the electronic atomization device to be screened is above 3.8V, the no-load voltage difference is measured to be 0.13V, the loaded voltage difference is 0.037V, and the preset internal control voltage value is 0.02V. Then, when detecting the battery voltage of the electronic atomization device, the output voltage value of the external DC power supply can be set to 3.8+0.13+0.037+0.02=3.987V.

[0073] In a possible implementation, determining the battery voltage value range of the electronic atomization device according to the battery display status of the electronic atomization device includes:

[0074] When the battery display status of the electronic atomization device is rechargeable, it is determined that the battery voltage value of the electronic atomization device is less than the preset screening voltage value;

[0075] When the battery display status of the electronic atomization device is not rechargeable, it is determined that the battery voltage value of the electronic atomization device is greater than or equal to the preset screening voltage value.

[0076] It should be noted that the battery voltage value range of the electronic atomization device can be determined by the battery display status of the electronic atomization device, specifically: when the battery display status of the electronic atomization device is rechargeable, it means that the battery can be charged at this time, which means that the battery voltage is less than the output voltage value, that is, the battery voltage value range is less than the preset screening voltage value; when the battery display status of the electronic atomization device is non-rechargeable, it means that the battery is fully charged at this time, which means that the battery voltage is greater than or equal to the output voltage value, that is, the battery voltage value range is greater than or equal to the preset screening voltage value.

[0077] Continuing with the above example, when the external DC power supply is connected to the battery charging port of the electronic atomization device for charging, if the battery of the electronic atomization device is displayed as chargeable, the battery voltage value of the electronic atomization device is less than 3.987V; if the battery of the electronic atomization device is displayed as non-chargeable, the battery voltage of the electronic atomization device is greater than or equal to 3.987V.

[0078] Specifically, in this embodiment, the voltage detection method of the above-mentioned electronic atomization device is verified. By selecting an electronic atomization device with a battery voltage of 3.8V or above, this verification verifies batteries in different voltage ranges, as shown in Table 1. Table 1 is the experimental results of battery voltage detection of different electronic atomization devices.

[0079] Table 1 Experimental results of battery voltage detection of different electronic atomization devices

[0080]

[0081] It can be seen from Table 1 that when the battery voltage value of the electronic atomization device is higher than the preset screening voltage value, the battery display status of the electronic atomization device is non-rechargeable; when the battery voltage value of the electronic atomization device is higher than the preset screening voltage value, the battery display status of the electronic atomization device is rechargeable. By setting the output voltage value of the external DC power supply according to the above method, the battery voltage value range of the electronic atomization device can be accurately identified.

[0082] In a possible implementation, the preset current value is 50 mA.

[0083] It should be noted that in the embodiment of the present application, the regulated current of the external DC power supply is set to a preset current value, and the preset current value is set to 50mA. Also, in the process of charging the battery of the electronic atomization device by the external DC power supply according to the output voltage value, the current of the external DC power supply is also set to 50mA. Through the above settings, the external DC power supply provides a constant current value to ensure safety during the detection process.

[0084] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. 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 embodiments of the present application.

[0085] Corresponding to the voltage detection method of an electronic atomization device in the above embodiment, Figure 2 A structural schematic diagram of a voltage detection system for an electronic atomization device provided in one embodiment of the present application is shown. For ease of explanation, only the parts related to the embodiment of the present application are shown.

[0089] Specifically, the voltage detection system 2 of the electronic atomization device is composed of an external DC power supply 21, a charging line 22 and a special test fixture 23. When the battery voltage of the electronic atomization device is detected, the electronic atomization device 24 is first placed on the special test fixture 23, and the second port of the charging line 22 is fixed on the special test fixture 23, and the positive and negative ends of the external DC power supply 21 are connected to the first port of the charging line 22, and the battery charging port of the electronic atomization device 24 is connected to the second port of the charging line 22. After that, the output voltage value and the output current value of the external DC power supply 21 are set. Among them, the output voltage value is determined according to the preset screening voltage value, the no-load voltage difference and the loaded voltage difference when the voltage of the electronic atomization device 24 is detected by the external DC power supply 21; the no-load voltage difference is used to characterize the voltage difference caused by the impedance generated when the external DC power supply 21 is connected to the battery; the loaded voltage difference is used to characterize the voltage difference between the battery and the external DC power supply 21 when charging.

The voltage detection system 2 of the electronic atomization device can detect the battery voltage of the electronic atomization device 24 without disassembling the device, thereby screening out the electronic atomization device 24 with the required battery voltage value.
