This design enhances the stability and controllability of the injection assembly 10, allowing the injection needle 11 to more accurately inject the e-cigarette liquid sample into the injection hole 31 on the tray 7, thereby improving the accuracy and reliability of the test.

[0042] In a specific embodiment, the tray 7 includes a clamping bracket 14, a clamping plate 15 and a clamping assembly plate 16. The clamping bracket 14 is arranged on the mounting plate 6, the clamping plate 15 is clamped on the clamping bracket 14, the clamping plate 15 has a mounting hole 17, and the clamping assembly plate 16 is arranged on the mounting hole 17.

[0043] Specifically, the clamping bracket 14 is fixed to the mounting plate 6 by bolts, screws, etc., providing stable support for the clamping plate 15; the clamping plate 15 is used to place the clamping plate group 16 containing the e-cigarette oil sample; the clamping plate group 16 is detachably placed on the mounting hole 17 of the clamping plate 15 to fix the position of the e-cigarette oil sample. This allows the e-cigarette oil sample to be firmly placed on the tray 7 to prevent movement or leakage during the test, thereby ensuring the accuracy and reliability of the test. The clamping plate group 16 further fixes the position of the e-cigarette oil sample to prevent it from displacement or deformation during the test. This design not only improves the accuracy and reliability of the test, but also facilitates the operator to place and remove the sample.

[0044] In a specific embodiment, the clamping bracket 14 includes a clamping column 18, a fixing block 19 and a fixing member 20, one end of the fixing block 19 is arranged on the clamping column 18, and the other end is arranged on the clamping plate 15, and the clamping column 18 has a limiting groove 21, and the side of the clamping plate 15 has a sliding block 22, and the sliding block 22 is arranged in the limiting groove 21, wherein the fixing block 19 has a first fixing hole 23, the clamping plate 15 has a second fixing hole 24, and the fixing member 20 passes through the first fixing hole 23 and the second fixing hole 24.

[0045] Specifically, one end of the fixing block 19 is fixed to the clamping column 18 by bolts, screws, etc., and the other end extends to the clamping plate 15; the limiting groove 21 on the clamping column 18 cooperates with the sliding block 22 on the side of the clamping plate 15 to ensure that the clamping plate 15 can slide smoothly on the clamping column 18; the first fixing hole 23 on the fixing block 19 corresponds to the second fixing hole 24 on the clamping plate 15, and the clamping plate 15 and the clamping column 18 are tightly connected together through the fixing member 20 to form a stable support structure. This allows the clamping bracket 14 to more firmly fix the clamping plate 15, preventing it from moving or tilting during the test. At the same time, the presence of the fixing block 19 and the fixing member 20 can further increase the stability and reliability of the clamping bracket 14. This design not only improves the accuracy and reliability of the test, but also facilitates the operator to place and remove samples.

[0046] In a specific embodiment, the clamping plate 15 includes a first pressing plate 25 and a second pressing plate 26, and the first pressing plate 25 and the second pressing plate 26 are arranged opposite to each other on the clamping plate 15, wherein the first pressing plate 25 has a pressing portion 27, and the pressing portion 27 is arranged on the mounting hole 17 to press against the clamping assembly plate 16.

[0047] Specifically, the first pressing plate 25 and the second pressing plate 26 are fixedly connected to the clamping plate 15 via screws, bolts, etc. The first pressing plate 25 and the second pressing plate 26 are used to press the clamping plate assembly 16. The first pressing plate 25 and the second pressing plate 26 work together to secure the e-cigarette liquid sample. This design allows the e-cigarette liquid sample to be placed more securely on the placement plate 30, preventing leakage or movement during testing. The e-cigarette liquid sample is placed in an appropriate position on the clamping plate assembly 16, and then the clamping plate assembly 16 is secured using the first pressing portion 27 of the first pressing plate 25 and the second pressing portion 27 of the second pressing plate 26.

[0048] In a specific embodiment, the clamping plate assembly 16 has a first clamping plate 28, a second clamping plate 29 and a placement plate 30, the placement plate 30 is clamped between the first clamping plate 28 and the second clamping plate 29, the first clamping plate 28 and the second clamping plate 29 have a connecting injection hole 31, and the injection needle 11 can be inserted into the injection hole 31.

[0049] Specifically, both the first and second clamping plates 28 and 29 are made of transparent glass, providing a clear field of view for observing the diffusion of the e-vapor sample. The placement plate 30 is a fabric-like structure used to hold the e-vapor sample. This fabric has a certain degree of adsorption, which facilitates the volatilization and diffusion of the e-vapor sample, ensuring more reliable test results. The injection needle 11 can be inserted into the injection hole 31 and accurately inject the e-vapor sample through the injection hole into the placement plate 30. The injection needle 11 automatically controls the injection volume and speed, eliminating the errors and risks associated with manual operation.

[0050] In a specific embodiment, the light source assembly 8 includes a first light-emitting group 32 and a second light-emitting group 33, and the first light-emitting group 32 and the second light-emitting group 33 are both arranged on the mounting plate 6, and the first light-emitting group 32 is arranged on one side of the surface of the tray 7, and the second light-emitting group 33 is arranged on the other side of the surface of the tray 7.

[0051] Specifically, the primary function of light source assembly 8 is to provide uniform and stable lighting conditions throughout the test area. A first light group 32 is positioned above one side of the tray 7, at the same level as the injection needle 11. A second light group 33 is positioned on the other side of the tray 7. Both light groups 32 and 33 are positioned close to the inside of the tray 7, illuminating from a low angle outside the sample area. This prevents light from reflecting off the glass holding the sample and being captured by lens assembly 9, which could affect the measurement results.

[0052] In a specific embodiment, the first light-emitting group 32 includes a connecting plate 34 and a light bar 35 . The connecting plate 34 extends from the surface of the mounting plate 6 in a direction parallel to the surface of the workbench 1 . The light bar 35 is provided on the connecting plate 34 .

[0053] Specifically, the main function of the connecting plate 34 is to provide a stable foundation for supporting and fixing the light strip 35. The connecting plate 34 extends from the surface of the mounting plate 6 in a direction parallel to the surface of the workbench 1 to ensure that the position and angle of the light source assembly 8 meet the design requirements, thereby providing uniform lighting conditions.

[0054] In a specific embodiment, the lens assembly 9 includes a first lens 36 and a second lens 37 , and the first lens 36 and the second lens 37 are disposed opposite to each other on the mounting plate 6 .

[0055] Specifically, when observing in a direction parallel to the surface of the tray 7, the first lens 36 is set above the surface of the tray 7, and the second lens 37 is set below the surface of the tray 7. By capturing the image of the diffusion of the electronic smoke sample from different angles, the blind spot is reduced.

[0056] In a specific embodiment, the first lens 36 includes a first connecting column 38 and a first camera 39, one end of the first connecting column 38 is connected to the first camera 39, and the other end of the first connecting column 38 is connected to the mounting plate 6, the second lens 37 includes a second connecting column 40 and a second camera 41, one end of the second connecting column 40 is connected to the second camera 41, and the other end of the second connecting column 40 is connected to the mounting plate 6, wherein the tester also includes a computer, and the first camera 39 and the second camera 41 are both connected to the computer.

[0057] Specifically, the first camera 39 and the second camera 41 are used to capture image data during the diffusion process of the electronic smoke sample. The first camera 39 observes the diffusion of the electronic smoke sample on one side, and the second camera 41 observes the diffusion of the electronic smoke sample on the other side. The lens light of the first camera 39 and the second camera 41 are aligned and pass through the injection hole 31 together. By shooting the sample from different angles, more comprehensive image information can be obtained, which is helpful for subsequent data processing and analysis. The computer is responsible for receiving the image data from the first camera 39 and the second camera 41, and storing, processing and analyzing it. Through specialized software, the computer can automatically identify the particulate matter in the image, calculate its concentration distribution and other key parameters, and display the results to the user.

[0058] The above is only an implementation method of the present application. It should be pointed out that for ordinary technicians in this field, improvements can be made without departing from the creative concept of the present application, but these all fall within the scope of protection of the present application.
