Description

Technical Field

[0001] This invention relates to the field of electronic atomizer testing technology, and more specifically, to an electronic atomizer performance testing device and method. Background Technology

[0002] Electronic atomizers, commonly known as e-cigarettes, are electronic products that mimic traditional cigarettes and are classified as new types of tobacco products. They use a battery-powered atomizer to heat and vaporize e-liquid containing nicotine, flavorings, and other ingredients into an aerosol, which the user inhales to simulate the pleasure of smoking.

[0003] As a substitute for traditional cigarettes, electronic atomizers, in addition to their inhalation flavor, also affect the user's experience through the actual vapor production. For example, at the same inhalation speed, the rate of vapor formation and diffusion, as well as the particle concentration of vapor in the same volume, all represent the actual performance of the electronic atomizer to a certain extent.

[0004] Therefore, in actual testing, a set of devices capable of constant-speed and quantitative suction can be used to simulate the suction of the electronic atomizer and draw the smoke into a transparent container. Then, visual recognition technology is used to visually identify the entire process of smoke generation to determine the smoke emission speed (e.g., the time required from smokeless generation to the smoke filling the entire transparent container, as well as the diffusion shape and speed of the smoke at the front end during the smoke emission process). Then, a particulate matter concentration detection device (e.g., a laser smoke concentration detector) is used to detect the particulate matter concentration of the smoke (particulate matter concentration and particle size distribution are key indicators for measuring the core performance of the atomizer and directly affect the user's actual experience). At the same time, other types of detection equipment may be added during the actual testing process according to other needs.

[0005] However, during the product development stage, and for important types of electronic atomizer products, repeated testing is required during actual testing. The transparent container can easily retain the smoke generated from the previous inhalation, which mixes with the smoke generated from the next simulated inhalation, thus affecting the actual testing results in subsequent testing processes and hindering the effective evaluation of actual product development improvements. Summary of the Invention

[0006] The present invention provides an electronic atomizer performance testing device and method, which aims to solve the problem that when repeated tests are required, the smoke generated by the previous inhalation is easily retained in the transparent container and mixed with the smoke generated by the next inhalation, affecting the actual testing effect in the subsequent testing process and the effective evaluation of actual product development and improvement.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an electronic atomizer performance testing device, comprising a transposition base, a smoke detection component, and a concentration detection component.

[0011] Preferably, an automatic sealing device is provided in the through hole of the second fixed seat.

The one-way valve is used to allow air in the piston cylinder to flow out when the piston resets. An active sealing device is provided in the through hole of the first fixed seat. The active sealing device adopts a control valve.

[0012] Preferably, an air guide hood is installed in both the first and second fixed seats. A narrow gap is formed between the air guide hood and the inner wall of the transparent container. A flat air blowing channel is formed between the air guide hood on the first fixed seat and the inner wall of the transparent container. A flat air suction channel is formed between the air guide hood on the second fixed seat and the inner wall of the transparent container. An air equalization ring cavity is provided in both the first and second fixed seats. The air blowing pipe is connected to the air equalization ring cavity in the first fixed seat, and the air suction pipe is connected to the air equalization ring cavity in the second fixed seat. The air blowing pipe is also connected to the through hole in the second fixed seat. A connecting channel is provided between the air equalization ring cavity and the narrow gap between the air guide hood and the transparent container.

[0013] Preferably, the suction simulation component further includes a cleaning structure, which includes multiple atomizing nozzles on an air guide hood disposed in the first fixed base. The atomizing nozzles are disposed on the corresponding surfaces of the air guide hood and the inner wall of the transparent container, and multiple atomizing nozzles are disposed thereon. The multiple atomizing nozzles are evenly distributed circumferentially on the air guide hood. A liquid equalization ring cavity is disposed inside the air guide hood. A liquid supply pipe is fixedly installed on the first fixed base, extending into the interior of the air guide hood and communicating with the liquid equalization ring cavity through the internal flow channel of the air guide hood. The atomizing nozzles are connected to the liquid equalization ring cavity. The liquid supply pipe is connected to a cleaning agent pumping structure through a pipeline. A liquid collection ring cavity is disposed inside the second fixed base, and a liquid extraction pipe is disposed at the bottom of the liquid collection ring cavity. The liquid collection ring cavity is connected to the suction flat flow channel.

[0014] Preferably, a first rotating sleeve and a second rotating sleeve are respectively installed at both ends of the transparent container. The first rotating sleeve is rotatably installed with the first fixed seat, and the second rotating sleeve is rotatably installed with the second fixed seat. A container rotation control component is also installed on the rotating seat. The container rotation control component is used to drive the second rotating sleeve to rotate, so as to drive the transparent container to rotate.

[0015] Preferably, the first rotating sleeve includes a first rotating ring and a container fixing ring.

A fixing ring is fixedly installed on the outer side of the transparent container near the second fixed base, and a single-point counterweight is fixedly installed on the fixing ring.

[0016] A method for testing the performance of an electronic atomizer includes the following steps: Step 1: Insert the electronic atomizer into the mouthpiece socket of a set of vaping simulation components; Step 2: Control the group of suction simulation components to reach below the visual recognition camera, and control the suction control component to draw air once in a quantitative manner, so that the electronic atomizer generates smoke and the smoke flows into the transparent container. At the same time, use the visual recognition camera to visually recognize and detect the smoke entering the transparent container. Step 3: Simultaneously turn on the blowing and suction devices, so that the blowing tube blows air at the first fixed seat and the suction tube draws air at the second fixed seat to expel the original smoke from the transparent container. Step 4: Control the group of suction simulation components to reach below the laser emitting unit, and control the suction control component to pump air quantitatively once again. After the smoke fills the transparent container, turn on the laser emitting unit to emit laser light, and the photoelectric receiving unit receives the laser light to detect the smoke concentration. Step 5: Turn on the blowing and suction devices simultaneously again, so that the blowing tube blows air at the first fixed seat and the suction tube draws air at the second fixed seat to expel the original smoke from the transparent container. Step 6: Repeat the above operation 50-100 times. End the test after completing the repetition.

[0017] The beneficial effects of this invention are as follows: This invention creates a new air circulation within the transparent container after each suction and test, thereby removing the smoke generated during the previous test through the suction tube. This ensures that no smoke from the previous test remains in the transparent container during the next simulated test, further improving the test results and effectively reducing the impact on the evaluation of actual product development and improvement.

[0018] After the test is completed and the smoke is completely discharged, the present invention sprays atomized cleaning agent into the air blowing flat channel through the atomizing nozzle. With the help of the airflow blown out by the air blowing flat channel, the cleaning agent can flow along the inner wall of the transparent container to the second fixed seat, thereby automatically cleaning the inner wall of the transparent container after each test.

[0019] This invention utilizes a smoke detection component for visual recognition and detection of smoke entering a transparent container, and a concentration detection component to measure the smoke concentration within the transparent container. This not only allows for the intuitive quantification of core hardware performance such as the heating efficiency of the atomizer core, battery life stability, and airtightness of the airway design, but also enables the prediction of e-liquid's vapor production capacity and user taste experience through the visual density and shape of the smoke. This provides strong objective data support for the research and development optimization, quality control, and safety compliance of e-cigarettes. Attached Figure Description

[0022] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0023] Refer to the instruction manual appendix Figure 1 and Figure 2 An electronic atomizer performance testing device includes a switching base 1, a smoke detection component 11, and a concentration detection component 12. The smoke detection component 11 is equipped with multiple sets of suction simulation components. The switching base 1 is used to drive the suction simulation components to switch positions between the smoke detection component 11 and the concentration detection component 12.

[0024] The suction simulation assembly includes a transparent container 2 (preferably cylindrical) and a suction control assembly 4. The transparent container 2 is mounted on the transposition base 1 via a container support assembly 3. The container support assembly 3 includes a first fixing base 31 and a second fixing base 32, which are located at opposite ends of the transparent container 2. Both the first fixing base 31 and the second fixing base 32 have through holes 301 communicating with the inner cavity of the transparent container 2. The first fixing base 31 has a mouthpiece insert 33 for inserting an electronic atomizer. The device is equipped with a sealing structure that is compatible with the electronic atomizer (i.e., after the electronic atomizer is inserted into the mouthpiece sleeve 33, it can be relatively sealed. In order to facilitate the insertion of the electronic atomizer, the mouthpiece sleeve 33 is preferably made of rubber, which facilitates the automatic fixation of the electronic atomizer after insertion and allows for direct sealing). The suction control component 4 is connected to the second fixing base 32, and the suction control component 4 is used to create a negative pressure inside the transparent container 2, so as to draw the smoke generated by the electronic atomizer into the transparent container 2, thus completing the suction simulation component's simulation of the electronic atomizer's suction.

[0025] The smoke detection component 11 is used for visual recognition detection of smoke entering the transparent container 2. The smoke detection component 11 includes a visual recognition camera 111 and other corresponding devices required for conventional visual recognition detection and recording, such as lights. The visual recognition camera 111 performs real-time visual recognition of the specific situation of the transparent container 2, recording the smoke from the start of suction control component 4, recording when the smoke begins to enter the transparent container 2, and recording the initial diffusion state of the smoke entering the transparent container 2 (diffusion speed, diffusion direction, and smoke color, etc.). It can also record... Under the same inhalation volume, different tests are conducted using a transparent container 2 to measure the distribution of smoke within the container (e.g., whether it fills the entire container 2). This not only allows for a direct quantification of core hardware performance such as the heating efficiency of the atomizer core, battery life stability, and airtightness of the airway design, but also enables the prediction of e-liquid's vapor production capabilities and user taste experience through the visual density and shape of the smoke. Furthermore, by identifying abnormal smoke diffusion or color changes, it effectively warns of safety hazards such as "spitting out" and dry burning, as well as the risk of secondhand smoke spreading in the environment. This provides strong objective data support for the research and development optimization, quality control, and safety compliance of e-cigarettes.

[0026] The smoke detection component 11 is mainly used for basic assessment of the electronic atomizer's performance. For certain important performance aspects, more precise testing is required. For example, the concentration detection component 12 is used to detect the smoke concentration (particulate matter concentration) inside the transparent container 2. The concentration detection component 12 primarily employs a laser smoke concentration detection device. For instance, as the laser passes through the smoke, the laser beam is weakened; the higher the smoke concentration, the less energy the laser penetrates. By comparing the laser intensity difference between the transmitting and receiving ends, the concentration can be calculated. The concentration detection component 12 includes a laser emitting unit 121 and a photoelectric receiving unit 12. 2. The laser emitting unit 121 is used to emit a laser and make the laser pass through the transparent container 2 and the smoke inside the transparent container 2 (the area below the transparent container 2 corresponding to the transposition seat 1 is provided with a window so that the laser can pass through completely). The photoelectric receiving unit 122 receives and detects the laser passing through the transparent container 2 and the smoke, and measures the attenuation of the laser after passing through the smoke to determine the smoke concentration. This further accurately reflects the heating efficiency of the atomizing core, the stability of battery power supply and the persistence of atomization output. By measuring the aerosol concentration and particle size distribution, the "throat hit" and intensity of the product can be objectively predicted, replacing the traditional subjective taste evaluation.

[0027] It should be noted that the smoke detection component 11 and the concentration detection component 12 mentioned above are conventional equipment in the detection field. When making specific selections, they can be selected and set according to the actual production and detection conditions. Therefore, their specific solutions will not be explained in detail in this embodiment. When the concentration detection component 12 is monitoring, it is necessary to ensure that the transparent container 2 is filled with smoke. Therefore, when the simulated suction component reaches the concentration detection component 12, the suction control component 4 can be controlled to perform twice the suction.

[0028] Further, please refer to the appendix to the instruction manual. Figure 2 and Figure 3 The testing device of the present invention also includes a ventilation control component 5, which includes multiple sets of blowing pipes 51 and suction pipes 52 (each suction simulation component is equipped with a set of blowing pipes 51 and suction pipes 52), see the attached specification. Figure 5 and Figure 6 The blowing pipe 51 is installed on the first fixed base 31, and the suction pipe 52 is installed on the second fixed base 32. The blowing pipe 51 and the suction pipe 52 are connected to the blowing equipment (blowing pump) and the suction equipment (suction pump) respectively through a transfer structure. The blowing pipe 51 blows air at the end of the transparent container 2 near the first fixed base 31, and the suction pipe 52 draws air at the end of the transparent container 2 near the second fixed base 32. This creates an airflow from the first fixed base 31 to the second fixed base 32 inside the transparent container 2. After each suction and test, a new air circulation is formed inside the transparent container 2, which removes the smoke generated in the previous test through the suction pipe 52. This ensures that no smoke from the previous test remains in the transparent container 2 during the next simulation test, further improving the test effect and effectively reducing the impact on the evaluation of actual product development and improvement.

[0029] It should be noted that, for convenient repeated use, please refer to the instruction manual attached. Figure 2 The switching base 1 can be configured as a turntable structure, which is rotatably mounted on the base and driven to rotate by a motor or other structure. Multiple sets of suction simulation components are arranged radially on the switching base 1, with the mouthpiece sleeve 33 facing outward to facilitate the installation of the electronic atomizer. By rotating the switching base 1, the suction simulation components can be switched between different positions. At the same time, other types of detection components can be set on the base as needed to conduct other performance and quality tests, and each detection component is arranged around the switching base 1.

[0030] Correspondingly, since the suction simulation component rotates in one direction along with the transposition seat 1 during actual testing, please refer to the instruction manual appendix for convenient air path connection. Figure 3 and Figure 6The transfer structure includes a transfer seat 53 and a rotating sleeve 54. The rotating sleeve 54 is fixedly installed on the transfer seat 1 and rotates together with each set of suction simulation components. The transfer seat 53 is rotatably installed inside the rotating sleeve 54. The circumferential side wall of the transfer seat 53 is provided with an air blowing ring groove 531 and an air suction ring groove 532. The rotating sleeve 54 is provided with multiple sets of air blowing connectors 511 and air suction connectors 521. Each set of air blowing connectors 511 and air suction connectors 521 corresponds to a set of air blowing pipes 51 and air suction pipes 52. The air blowing connector 511 is connected to the corresponding air blowing pipe 51 through a pipe, and the air suction connector 521 is connected to the corresponding air suction pipe 52 through a pipe. The two are connected, and each air blowing connector 511 is connected to the air blowing ring groove 531, and each air suction connector 521 is connected to the air suction ring groove 532. The intermediate base 53 is also fixedly installed with an air blowing control pipe 55 and an air suction control pipe 56. The air blowing control pipe 55 is connected to the air blowing equipment (air blowing pump) through a pipeline, and the air suction control pipe 56 is connected to the air suction equipment (air suction pump) through a pipeline. The intermediate base 53 can use a bracket or other structure, or rely on the fixed restriction of the air blowing control pipe 55 and the air exchange control component 5 itself to make the rotating sleeve 54 rotate while the intermediate base 53 remains stationary, so as to provide an effective air path connection when the suction simulation component rotates.

[0031] In the above embodiments, the suction control component 4 can use a pump structure with quantitative suction, or a corresponding piston suction structure can be designed according to requirements, for example, as shown in the appendix of the instruction manual. Figure 5 The suction control assembly 4 includes a piston cylinder 41 and a piston 42. The piston cylinder 41 is fixedly installed on the shifting seat 1 and is connected to the second fixed seat 32. The piston 42 is slidably installed in the piston cylinder 41. The piston 42 is driven to move by the piston controller 43. The piston controller 43 can be a conventional moving drive device or a screw drive device. That is, a set of motors and screws are set, the screws are threadedly connected to the piston 42, and a limiting structure is set in the piston cylinder 41 to restrict the rotation of the piston cylinder 41. The piston 42 can be driven to move by controlling the rotation of the screw. This method is simpler and more precise.

[0032] It should be noted that the main function of the suction control component 4 is to simulate human inhalation, so the suction control component 4 mainly plays a role in quantitative suction. To prevent smoke from entering the piston cylinder 41, an automatic sealing device 321 can be installed in the through hole 301 of the second fixed seat 32, as shown in the attached instruction manual. Figure 7When the suction control assembly 4 is suctioning (i.e., when the piston 42 moves away from the first fixed seat 31), the automatic sealer 321 allows air in the transparent container 2 to move into the piston cylinder 41. Therefore, the automatic sealer 321 can adopt a simple combination of rubber plate and fiber structure to form a simple one-way valve structure. At the same time, a one-way valve is also provided in the piston 42. This one-way valve is used to allow air in the piston cylinder 41 to flow outward when the piston 42 is reset (i.e. when it moves towards the first fixed seat 31).

[0033] Furthermore, in the above-mentioned scheme, with the continuous development of electronic atomizers and the e-liquids they are used with, many new materials are being used in both the electronic atomizers themselves and the e-liquid substances. For example, there are atomizing materials based on porous ceramics and new e-liquid formulation materials based on nicotine salts. The integration of these new materials has further improved the actual performance of electronic atomizers in research and development and production. Therefore, in order to obtain more comprehensive test data, especially for electronic atomizers and e-liquids in the research and development stage, continuous, multiple, and long-term cyclical tests are required (i.e., continuous inhalation through the inhalation control component 4 and continuous detection through the smoke detection component 11 and the concentration detection component 12). This is to determine the initial performance of the product and to test the performance changes of the product after long-term use, thereby providing more comprehensive basis for product design and development.

[0034] However, because the vapor from electronic atomizers still contains substances that easily adhere to the vapor, such as nicotine, and especially because some new e-liquids contain added flavorings or other substances, these substances also tend to adhere after vapor formation. Although the amount is small and has little impact on a single test, when using the same set of transparent containers 2 for extended periods and multiple consecutive tests, these substances can easily adhere to the inner wall of the transparent containers 2, affecting optical testing, especially laser detection. Therefore, this embodiment also makes preliminary improvements to the vaping simulation component. For details, please refer to the attached instruction manual. Figure 7 An air guide hood 34 is installed in both the first fixed base 31 and the second fixed base 32. A narrow gap is formed between the air guide hood 34 and the inner wall of the transparent container 2. A flat air blowing channel 303 is formed between the air guide hood 34 on the first fixed base 31 and the inner wall of the transparent container 2, and a flat air suction channel 304 is formed between the air guide hood 34 on the second fixed base 32 and the inner wall of the transparent container 2. An air equalization ring cavity 302 is provided in both the first fixed base 31 and the second fixed base 32. The air blowing pipe 51 is connected to the air equalization ring cavity 302 in the first fixed base 31, and the air suction pipe 52 is connected to the air equalization ring cavity 302 in the second fixed base 32. At the same time, it is also connected to the through hole 301 in the second fixed base 32. A connecting channel is provided between the air equalization ring cavity 302 and the narrow gap between the air guide hood 34 and the transparent container 2.

[0035] In actual use, after a single test, the blowing pipe 51 blows air and the suction pipe 52 draws air, accelerating the discharge of smoke from the transparent container 2. Due to the presence of the blowing flat flow channel 303 and the suction flat flow channel 304, a corresponding air curtain can be formed on the inner wall of the transparent container 2 first, reducing the impact contact between the particles that are easily attached in the smoke and the inner wall of the transparent container 2 when the smoke is discharged, thereby reducing the adhesion of particulate matter on the inner wall of the transparent container 2 and reducing the impact on subsequent testing.

[0036] Furthermore, given the high oil content and numerous attached particulate matter in the vapor, coupled with the frequent detections by a single electronic atomizer, simply reducing the collisions between particulate matter and the inner wall of the transparent container 2 is insufficient to completely eliminate particulate matter adhesion. Therefore, this embodiment also incorporates a secondary improvement to the suction simulation component. For details, please refer to the appendix of the instruction manual. Figure 8 and Figure 9 The suction simulation component also includes a cleaning structure, which comprises multiple atomizing nozzles 6 mounted on an air guide hood 34 located in the first fixed base 31. The atomizing nozzles 6 are positioned on the corresponding surfaces of the air guide hood 34 and the inner wall of the transparent container 2, and multiple nozzles 6 are evenly distributed circumferentially on the air guide hood 34. An equalizing ring cavity 341 is provided inside the air guide hood 34. A liquid supply pipe 61 is fixedly mounted on the first fixed base 31, extending into the interior of the air guide hood 34 and passing through… The internal flow channel of the air guide hood 34 is connected to the liquid equalization ring cavity 341, and the atomizing nozzle 6 is connected to the liquid equalization ring cavity 341. The liquid supply pipe 61 is connected to the cleaning agent pumping structure through the pipeline, and flows into the combination of alcohol and pump, so that the atomizing nozzle 6 can spray atomized cleaning agent into the blowing flat flow channel 303. With the help of the airflow blown out by the blowing flat flow channel 303, the cleaning agent can flow along the inner wall of the transparent container 2 to the second fixed seat 32, and thus automatically clean the inner wall of the transparent container 2 after each test.

[0037] In addition, please refer to the appendix to the instruction manual. Figure 10 The second fixed base 32 is also provided with a liquid collection ring cavity 305. The bottom of the liquid collection ring cavity 305 is provided with a liquid extraction pipe 62. The liquid collection ring cavity 305 is connected to the air suction flat flow channel 304, so that excess cleaning agent liquid can flow into the liquid collection ring cavity 305 and then be discharged from the liquid extraction pipe 62.

[0038] It should be noted that in the above scheme, air can be blown first to expel the smoke from the replacement seat 1, and then cleaning agent can be sprayed for cleaning. To improve the cleaning effect, the blowing intensity of the flat airflow channel 303 can be increased. At this time, in order to prevent the airflow inside the transparent container 2 from being too strong and creating a suction effect on the electronic atomizer, an active sealing device 311 can also be installed in the through hole 301 of the first fixing seat 31, as shown in the instruction manual. Figure 9As shown, the active closure device 311 can use a conventional control valve or a simple closure structure, such as a sliding closure plate. The closure plate can be controlled to enter the through hole 301 of the first fixed seat 31 to form a blockage.

[0039] Meanwhile, in order to ensure that the cleaning agent is evenly distributed in the transparent container 2 and achieve a thorough cleaning effect, a first rotating sleeve 35 and a second rotating sleeve 36 are respectively installed at both ends of the transparent container 2. The first rotating sleeve 35 is rotatably installed with the first fixed base 31, and the second rotating sleeve 36 is rotatably installed with the second fixed base 32. A container rotation control component 37 is also installed on the switching base 1. The container rotation control component 37 is used to drive the second rotating sleeve 36 to rotate, thereby driving the transparent container 2 to rotate during cleaning. For example, a combination of motor and gear can be used as the container rotation control component 37. A gear ring structure can be set on the corresponding structure of the second rotating sleeve 36 for transmission, thereby realizing the rotation control of the transparent container 2.

[0040] Furthermore, refer to the appendix of the instruction manual. Figure 9 and Figure 10 The first rotating sleeve 35 includes a first rotating ring 351 and a container fixing ring 352. The first rotating ring 351 is rotatably mounted on the first fixing seat 31, and the container fixing ring 352 is fixedly mounted on the end of the transparent container 2. The container fixing ring 352 is connected to the first rotating ring 351 through an elastic ring plate 353. The second rotating sleeve 36 includes a second rotating ring 361, which is rotatably mounted on the second fixing seat 32 (a toothed ring can be provided on the second rotating ring 361 to cooperate with the container rotation control component 37). An elastic ring sleeve 362 is provided on the inner wall of the second rotating ring 361. The elastic ring sleeve 362 is fixedly connected to the outer wall of the end of the transparent container 2. Both the elastic ring plate 353 and the elastic ring sleeve 362 can be made of rubber. A fixing ring 21 is fixedly installed on the outside of the transparent container 2 near the second fixing seat 32. A single-point counterweight 22 is fixedly installed on the fixing ring 21.

[0041] By adopting the above scheme, while ensuring that the transparent container 2 can be driven to rotate, the elasticity of the elastic ring 362 allows the end of the transparent container 2 corresponding to the second fixed seat 32 to have a certain amount of movement to deviate from the axis. That is, under the centrifugal force of the single-point counterweight 22, the end of the transparent container 2 corresponding to the second fixed seat 32 can move and deviate. As a result, when the transparent container 2 rotates, the transparent container 2 as a whole can form a certain tilt state, which can intensify the flow intensity of the cleaning agent inside the transparent container 2 and create a certain amount of shaking of the cleaning agent, so that the cleaning agent can actively flow to the second fixed seat 32 and be collected.

[0042] Refer to the instruction manual appendix Figure 11The present invention also provides a method for testing the performance of an electronic atomizer, comprising the following steps: Step 1: Insert the electronic atomizer into the mouthpiece socket 33 of a set of vaping simulation components; Step 2: Control the group of suction simulation components to reach below the visual recognition camera 111, and control the suction control component 4 to draw a quantitative amount of air once, so that the electronic atomizer generates smoke and the smoke flows into the transparent container 2. At the same time, the visual recognition camera 111 records the generation and flow process of the smoke and performs visual recognition detection on the smoke entering the transparent container 2. Step 3: Simultaneously turn on the blowing and suction devices, so that the blowing pipe 51 blows air at the first fixed seat 31 and the suction pipe 52 sucks air at the second fixed seat 32, so as to expel the original smoke in the transparent container 2. Step 4: Control the group of suction simulation components to reach below the laser emitting unit 121, and control the suction control component 4 to pump air quantitatively once again. After the smoke fills the transparent container 2, turn on the laser emitting unit 121 to emit laser, and the photoelectric receiving unit 122 receives the laser, judges the attenuation of the laser, and detects the smoke concentration. Step 5: Turn on the blowing and suction devices simultaneously again, so that the blowing pipe 51 blows air at the first fixed seat 31 and the suction pipe 52 sucks air at the second fixed seat 32, so as to expel the original smoke in the transparent container 2. Step 6: Repeat the above operation 50-100 times. End the test after completing the repetition.

[0043] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the protection scope of the present invention.
