Description

Technical Field

[0001] This utility model relates to the technical field of electronic cigarette testing equipment, specifically an electronic cigarette microphone testing machine. Background Technology

[0002] Electronic cigarettes are electronic products that mimic cigarette smoke, smell, and taste to a certain extent.

[0003] The airflow sensor (commonly known as the "microphone") is an important component of e-cigarettes. It is essentially a miniature electroacoustic device whose main function is to detect the user's inhalation airflow and convert it into an electrical signal, which is then fed back to the e-cigarette's controller. Based on the electrical signal fed back from the "microphone," the e-cigarette's controller precisely controls the atomizer's on / off state and the amount of vapor output, enabling the e-cigarette to simulate the inhalation feedback of cigarettes to the greatest extent possible. Specifically, when the user inhales into the e-cigarette, a high-speed airflow is generated near the "microphone." The "microphone" can sense the change in airflow and convert it into an electrical signal, which is then fed back to the e-cigarette's controller.

[0004] Therefore, it is evident that the performance and stability of the e-cigarette microphone have a significant impact on the overall performance of the e-cigarette, and performance testing of the e-cigarette microphone is one of the important steps before it leaves the factory.

[0005] In conclusion, how to provide an electronic cigarette microphone testing machine that is simple to operate, easy to measure, and accurate has become an urgent problem to be solved. Utility Model Content

[0008] In the above technical solution, the microphone fixture is provided with a terminal block, which is adapted to be electrically connected to the microphone sample; the terminal block is electrically connected to the electrophysical quantity tester according to polarity.

[0009] In the above technical solution, the microphone fixture, the three-way pipe, the negative pressure sensor, the gas tank, and the vacuum generator are all mounted on the frame.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: The electronic cigarette microphone testing machine of this utility model provides negative pressure to the three-way pipe and microphone fixture through a vacuum generator and gas cylinder, simulating the user's inhalation action of electronic cigarette, thereby triggering the microphone sample.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] This embodiment provides an electronic cigarette microphone testing machine for testing microphone samples installed in electronic cigarettes.

[0017] The "microphone sample" mentioned above is specifically an airflow sensor, which can convert changes in airflow into electrical signals and feed them back to a host computer (such as the controller of an electronic cigarette).

[0018] Please see Figures 1-3 The electronic cigarette microphone testing machine in this embodiment includes a microphone fixture 2, a three-way pipe, a negative pressure sensor 3, a gas tank 4, and a vacuum generator 5.

[0019] In this embodiment, the microphone fixture 2, the three-way pipe, the negative pressure sensor 3, the gas tank 4, and the vacuum generator 5 are all mounted on the frame 8, which is a metal frame and is used to provide a structural support foundation for the electronic cigarette microphone testing machine of this embodiment.

[0020] The microphone fixture 2 is a metal fixture used to clamp and fix the microphone sample 1. Specifically, the microphone fixture 2 has at least one microphone socket 21, which matches the shape of the microphone sample 1. The user can insert the microphone sample 1 into the microphone socket 21 of the microphone fixture 2. At this time, the microphone sample 1 and the microphone socket 21 are interference-fitted to form an airtight connection structure.

[0021] Specifically, the tee pipe is an airtight tee hose made of soft plastic or rubber.

[0022] Among them, the negative pressure sensor 3 is a sensor that detects the physical quantity of air pressure value (specifically, negative pressure value).

[0023] Specifically, the gas tank 4 is a hollow tank with airtight properties, used to provide gas storage and buffer space.

[0024] The vacuum generator 5 is a device for creating a vacuum, used to provide negative pressure, such as a piston vacuum pump.

[0025] The microphone fixture 2 and the air tank 4 are respectively connected to both sides of the three-way pipe by air passages. The negative pressure sensor 3 is connected to a branch of the three-way pipe by air passages. The vacuum generator 5 is connected to the air tank 4 by air passages. It can be understood that the above air passage connections are all achieved through air-tight air pipes.

[0026] Furthermore, in order to supply power to the microphone sample 1 and test whether the electrical signal fed back by the microphone sample 1 is normal, the microphone fixture 2 is provided with a terminal 7, which is adapted to be electrically connected to the microphone sample 1; the terminal 7 is electrically connected to the electrical physical quantity tester according to polarity. In this embodiment, the two terminals 7 are positive and negative terminals, respectively, used to supply power to the microphone sample 1, and one terminal 7 is the test terminal, which is electrically connected to the electrical physical quantity tester, which is a voltmeter and ammeter.

[0027] The specific operating procedure for using the electronic cigarette microphone testing machine of this embodiment is as follows:

[0028] Step 1: Insert the microphone sample 1 into the microphone socket 21 of the microphone fixture 2, so that the microphone sample 1 and the microphone socket 21 are interference fit, thereby forming an airtight connection structure.

[0029] Step 2: Connect the wires that come with the microphone sample 1 to the terminals 7 of the microphone fixture 2 according to their polarity to supply power to the microphone sample 1 (achieved by connecting the two terminals 7 configured as positive and negative poles), and connect the signal output terminal of the microphone sample 1 to the electrical physical quantity tester (achieved by connecting the terminal 7 configured as the test pole).

[0030] Step 3: Start the vacuum generator 5 to put both the three-way pipe and the microphone socket 21 of the microphone fixture 2 into a negative pressure state, so that the microphone sample 1 obtains suction force and continuously increases the suction force on the microphone sample 1 (specifically, by increasing the power of the vacuum generator 5 to increase the negative pressure value of the three-way pipe and the microphone socket 21 of the microphone fixture 2) until the microphone sample 1 is triggered and started.

[0031] Step 4: Read the negative pressure value through the negative pressure sensor 3 to obtain the current absorption resistance value of the microphone sample 1, and directly read the feedback signal value of the microphone sample 1 through the electrophysical quantity tester 6. By comparing the absorption resistance value and the feedback signal value, determine whether the microphone sample 1 is in normal performance.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
