Detailed Implementation

[0018] Example: Figures 1 to 3 As shown, an electronic cigarette microphone comprehensive reliability tester includes a test platform 1.

A pressure resistance test component 4, a negative pressure test component 5, a cycle control circuit 6 and a self-starting detector 7 are arranged on the upper surface of the test platform 1. A clamping fixture component 9 is connected to the upper surface of the test platform 1. The self-starting detector 7 is electrically connected to a self-starting counter 8.

[0019] The test and replacement components include a power button 21, a circuit switching knob 22, a negative pressure button 23, and a count reset button 24. The power button 21 is electrically connected to the negative pressure test component. The circuit switching knob 22 is used to switch between the pressure withstand test component, the negative pressure test component 5, the cycle control circuit 6, and the self-starting detector 7. The count reset button 24 is electrically connected to the technical display screen 3. The negative pressure button 23 is connected to the negative pressure test component 5.

[0020] The withstand voltage test assembly 4 includes a power supply circuit 41, which is electrically connected to a pulse generation circuit 42. The power supply circuit 41 and the pulse generation circuit 42 are electrically connected to a withstand voltage control chip 43. The power supply circuit 41 is electrically connected to a power button 21. The pulse generation circuit 42 is electrically connected to a withstand voltage test connector 44. The withstand voltage test connector 44 is fixedly connected to the test platform 1.

[0021] The withstand voltage test component 4 ensures the stability of the output voltage through a power supply circuit 41. The power supply circuit 41 is a DC 3.7V circuit, typically composed of a power supply chip and a filter circuit. The pulse generation circuit 42 utilizes an integrated circuit chip and components such as capacitors and inductors to generate an 8V peak voltage with a pulse width of 100ms through a programmed control chip. By properly connecting the pulse generation circuit 42 to the DC 3.7V power supply circuit 41, it can output a peak voltage according to a set number of 10 pulses while maintaining normal power supply.

[0022] The self-starting detector 7 is electrically connected to the power supply circuit 41, and the self-starting counter 8 is electrically connected to the counting display screen 3. The self-starting detector 7 can detect when the electronic cigarette microphone self-starts, generating an electrical signal. By connecting the self-starting detector 7 to the self-starting counter 8, when a self-starting signal is output, the self-starting detector 7 generates an electrical signal to trigger the self-starting counter 8 to count. The counting result is displayed on the counting display screen 3. When the powered-on electronic cigarette microphone is placed on the test platform 1 or in a specified temperature and humidity environment, and the device is started, the self-starting counter 8 automatically records the number of self-starts of the electronic cigarette microphone during the process.

[0023] The negative pressure experimental component 5 includes a negative pressure generating component 51, which includes a vacuum pump 511. The vacuum pump 511 is fixedly connected to the test platform 1. The vacuum pump 511 is connected to a pressure sensor 512. The pressure sensor 512 is electrically connected to a pressure regulating valve 52. The pressure regulating valve 52 is connected to a negative pressure counter 53. The negative pressure counter 53 is electrically connected to the technical display screen 3.

[0024] The negative pressure is precisely adjusted to the range of 500-600Pa by the combination of the set air pressure sensor 512 and the air pressure regulating valve 52. The negative pressure generating component 51 counts each operation by the set negative pressure counter 53. The electronic cigarette microphone is connected to the negative pressure test component 5, the number of negative pressure inhalations is set to 100,000, the test program is started, and the negative pressure test component 5 performs inhalation operation according to the set air pressure and number of inhalations. During the test, the negative pressure counter 53 records and displays the number of inhalations and the current air pressure in real time on the counting display screen 3.

[0025] The loop control circuit 6 is electrically connected to the power supply circuit 41 and the negative pressure generating component 51, respectively. The loop control circuit 6 uses a microcontroller (such as a single-chip microcomputer) as the core control element. By writing a program, it precisely controls the time sequence of power-on delay of 4 seconds, negative pressure opening delay of 2 seconds, negative pressure closing delay of 5 seconds, and power-off delay of 10 seconds. When the loop is started after each power-on, the counting display screen 3 displays the number of loops.

[0026] The clamping fixture assembly 9 includes two downward limiting rods 92, and downward clamping blocks 91 are connected to the two downward limiting rods 92. One end of a downward clamping spring 93 is fixedly connected to the lower surface of the downward clamping block 91, and the other end of the downward clamping spring 93 is fixedly connected to the test platform 1. The downward clamping spring 93 is sleeved with the downward limiting rods 92.

[0027] This application utilizes a pressure resistance test component 4, a negative pressure test component 5, a cycle control circuit 6, and a self-starting detector 7 to conduct comprehensive tests on the electronic cigarette microphone, including pressure resistance, negative pressure lifespan, repeated power-on self-starting, and static self-starting counting. This comprehensively assesses the overall reliability of the Apple electronic cigarette microphone and overcomes the limitations of existing single-function testing equipment. Parameters such as the power supply circuit 41, pulse generation circuit 42, and vacuum pump 511 can be precisely set according to actual needs, improving the flexibility and accuracy of the test and better simulating various operating conditions of the electronic cigarette microphone in real-world use. The self-starting counter 8 and negative pressure counter 53 enable precise counting and judgment functions, providing objective and accurate data for the reliability assessment of the electronic cigarette microphone, thus contributing to improved quality and stability of electronic cigarette products.

[0028] Working principle: When conducting a pressure test using the pressure test assembly 4, the electronic microphone is connected to the pressure test connector 44 of the pressure test assembly 4, the test program is started, and the power supply circuit 41 and the pulse generation circuit 42 are controlled by the pressure control chip 43 to perform the test according to the set parameters. During the test, the working status of the electronic cigarette microphone is monitored in real time.

[0029] The self-start count recording test involves placing the powered-on electronic cigarette microphone on test platform 1 or in a specified temperature and humidity environment, activating the device, and automatically recording the number of self-starts of the electronic cigarette microphone during the process using the self-start counter 8.

[0030] The negative pressure life test involves connecting the electronic cigarette microphone to the negative pressure test component 5, setting the negative pressure inhalation count to 100,000, starting the test program, and having the negative pressure test component 5 perform inhalation operations according to the set air pressure and number of inhalations. During the test, the negative pressure counter 53 records the inhalation count and the current air pressure and displays the count on the display screen 3 in real time.

[0031] The repeated power-on self-start count monitoring experiment involves connecting the electronic cigarette microphone to the loop control circuit 6, starting the test program, and the control circuit operating according to the set time sequence and number of cycles: power-on delay of 4 seconds, negative voltage opening delay of 2 seconds, negative voltage closing delay of 5 seconds, and power-off delay of 10 seconds. After the test, the set number of 100 starts is compared with the actual number of starts displayed on the counting display screen 3.
