One of the core components of an aerosol generating device is an atomization core assembly, which usually includes a liquid guide and a heating element. The liquid guide transports the atomization medium to the heating element, and the heating element is used to provide heat to the atomization medium to atomize and generate aerosol.

[0003] The atomization core assembly determines the quality of the aerosol generating device and the user's inhalation experience, which makes the design and research of the atomization core assembly particularly important. However, there is a lack of methods and platforms for basic research on atomization core assemblies in the industry. The current mainstream testing and design methods are still based on the mode of manual puffing + adjustment + testing, which is highly subjective, and the working mechanism and detailed changes of the atomization core assembly cannot be visualized, nor can qualitative and quantitative analyses be carried out. Summary of the Utility Model

[0016] Optionally, the atomization test platform further includes a six-axis guide rail which is used to control the position of the observation and recording device in six directions: up, down, left, right, front, and back.

[0017] Optionally, the shells of the simulated oil storage chamber and the e-liquid injection chamber are both transparent for visual inspection of the oil volume.

[0018] Optionally, the atomization core fixing structure is a fixing structure with conductive function or a fixing structure with only fixing function.

[0022] The technical solution of the present utility model has the following advantages:

[0023] 1. The working mechanism and details of the atomization core assembly can be directly observed through the observation and recording device; the e-liquid injection chamber can be used to pre-place the e-liquid to be tested. The e-liquid is quantitatively injected into the simulated oil storage chamber through the first valve, then quantitatively discharged to the atomization core through the oil outlet, and then the working condition of the atomization core is observed through the observation and recording device, so as to realize the qualitative and quantitative analysis and research of the atomization core assembly, and eliminate the interference of subjective factors of manual puffing on the analysis results.

[0045] Please refer to Figure 1, an embodiment of the present utility model provides an atomization test platform, which includes a simulated oil tank 2, an e-liquid injection tank 1, a pressure adjustment device 3, an atomizer fixing structure 5, and an observation and recording device 6.

[0046] The e-liquid injection tank 1 stores the e-liquid to be tested, and the e-liquid to be tested can be placed in it in advance; the bottom end of the e-liquid injection tank 1 is connected to the top end of the simulated oil tank 2 through a pipeline, and a first valve 12 is provided on the pipeline. The first valve 12 is used to precisely control the e-liquid discharged from the e-liquid injection tank 1 into the simulated oil tank 2. The first valve 12 can be a manual valve or an electric valve, and this embodiment is not limited, as long as it can achieve quantitative oil injection into the simulated oil tank 2.

[0047] Please refer to Figure 2 and Figure 3 , the function of the simulated oil tank 2 is to simulate the oil storage tank of an electronic cigarette. An oil outlet 91 is provided at the bottom of the simulated oil tank 2 for discharging the e-liquid inside the simulated oil tank 2. The e-liquid discharged from the oil outlet 91 flows to the atomizer 7, and the atomizer 7 generates heat and atomizes the e-liquid after being powered on.

[0048] Please refer to Figure 3 , the pressure adjustment device 3 is connected to the simulated oil tank 2 and is used to adjust the air pressure inside the simulated oil tank 2, including increasing or decreasing the air pressure inside the simulated oil tank 2, so as to simulate the air pressure change scenario in the oil storage tank when a user sucks an electronic cigarette. To cooperate with the pressure adjustment device 3 and make the adjusted air pressure inside the simulated oil tank 2 visually observable, a pressure gauge 4 is also installed on the simulated oil tank 2. The probe of the pressure gauge 4 extends into the simulated oil tank 2, and the pressure gauge 4 is used to measure and display the air pressure inside the simulated oil tank 2.

[0049] The atomizer 7 is positioned below the oil outlet 91 through the atomizer fixing structure 5, and the e-liquid discharged from the oil outlet 91 flows onto the atomizer 7. Further, in order to facilitate the testing of multiple atomizers, the atomizer fixing structure 5 in this embodiment has the function of facilitating the disassembly and assembly of the atomizer 7.

[0050] The working condition of the atomizer is not observed by the human eye, but the working image and details of the atomizer are automatically observed and recorded by the observation and recording device 6; the observation and recording device 6 can adopt a camera with a built-in CPU or a camera connected to an electronic computer; the lens of the camera is aligned with the atomizer 7, and the type of the camera is not limited, but if the heat generation condition of the atomizer needs to be observed, an infrared camera is preferably used; the working image and details of the atomizer 7 are recorded by taking pictures with the camera, and then the test results are obtained by analyzing and comparing the images through the CPU.

[0051] An auxiliary device can also be used to control the movement of the observation and recording device 6, so that the observation and recording device 6 can observe and record from a better perspective; the auxiliary device is, for example, a guide rail 8, and the guide rail 8 can be an electric cylinder (the driver uses a stepper motor) or a lead screw guide rail driven manually and locked in position; the guide rail 8 can be a six-axis guide rail, and the six-axis guide rail is used to control the position of the observation and recording device 6 in six directions: up, down, left, right, front, and back. The six-axis guide rail is assembled in the X-axis, Y-axis, and Z-axis directions in space by three sections of the guide rail 8. The position of the first section of the guide rail farthest from the observation and recording device 6 is fixed. The first section of the guide rail controls the second section of the guide rail to move in the X-axis direction, the second section of the guide rail controls the third section of the guide rail to move in the Y-axis direction, and the third section of the guide rail controls the observation and recording device 6 to move in the Z-axis direction.

[0052] Please refer to Figure 1 and Figure 3 , for the atomization test platform proposed in this embodiment, the working mechanism and details of the atomization core assembly can be directly observed through the observation and recording device 6; the e-liquid injection chamber 1 can be pre-filled with the e-liquid to be tested. The e-liquid is quantitatively injected into the simulation oil chamber 2 through the first valve 12, and then quantitatively discharged to the atomization core 7 through the oil outlet 91. Then, the working condition of the atomization core 7 is observed through the observation and recording device 6, and qualitative and quantitative analysis and research of the atomization core assembly can be realized, excluding the interference of subjective factors of manual puffing on the analysis results.

[0053] Please refer to Figure 3 , as an implementation manner, the air pressure regulating device 3 uses a piston air cylinder 31, or a combination of a piston air cylinder 31 and a water pipe 32. The piston air cylinder 31 is communicated with the simulation oil chamber 2. By pulling and pushing the piston air cylinder 31, the inside of the simulation oil chamber 2 can be evacuated and depressurized; by pre-storing air in the piston air cylinder 31 and then pushing the piston, the inside of the simulation oil chamber 2 can be inflated and pressurized. The piston air cylinder 31 is communicated with the simulation oil chamber 2 through a pipeline, and a second valve 13 is arranged on the pipeline. When the piston air cylinder 31 is operated to make the air pressure in the simulation oil chamber 2 reach a certain level, the second valve 13 is closed, so that the air pressure in the simulation oil chamber 2 can be kept unchanged; when the air pressure regulating device 3 uses only the piston air cylinder 31, the second valve 13 is used to keep the air pressure in the simulation oil chamber 2 unchanged. When the air pressure regulating device 3 uses a combination of a piston air cylinder 31 and a water pipe 32, it is not necessary to keep the air pressure in the simulation oil chamber 2 unchanged by closing the second valve 13, but the air pressure in the simulation oil chamber 2 is automatically controlled to be unchanged by the water column in the water pipe 32.

[0054] One end of the water pipe 32 is connected to the simulated oil tank 2, and the other end is equipped with a water column. The water pipe 32 is not entirely filled with the water column, but only partially has a water column, and this water column is at a certain distance from the inner cavity of the simulated oil tank 2. When the air pressure in the simulated oil tank 2 changes, the water column will not enter the simulated oil tank 2; the water pipe 32 at least includes a section of U-shaped bend, and the water column is located within this U-shaped bend. When operating the piston air cylinder 31 to change the internal air pressure of the simulated oil tank 2, the external atmosphere will press the water column, causing a height difference between the liquid levels at both ends of the water column. After the position of the water column stabilizes, the air pressure in the simulated oil tank 2 can remain unchanged.

[0055] As an implementation method, transparent materials such as transparent glass and transparent plastic can be used as the outer shells of the simulated oil tank 2 and the e-liquid injection tank 1 to facilitate observing the e-liquid storage amounts in the simulated oil tank 2 and the e-liquid injection tank 1; it is also possible to adopt the method of opening a window in the height direction on an opaque outer shell and sealing a transparent material at the window to facilitate observing the e-liquid storage amounts.

[0056] Please refer to Figure 3 , as an implementation method, the atomizer fixing structure 5 can be designed as a fixing structure with conductive function, equivalent to an electrode. For example, the atomizer fixing structure 5 is made of a metal conductive material. After the atomizer is installed in the atomizer fixing structure 5, by energizing the atomizer fixing structure 5, the atomizer 7 can be energized to work; the atomizer fixing structure 5 can also just be a simple fixing structure, with a wire welded to the atomizer 7 and the wire connected to an external power supply device.

[0057] Please refer to Figure 3 , as an implementation method, a seal 9 can be fixedly arranged at the bottom of the simulated oil tank 2, and the seal 9 is used to seal the simulated oil tank 2; an atomizer installation position is arranged at the bottom of the seal 9 for installing the atomizer fixing structure 5; an oil outlet 91 for the e-liquid to flow out is arranged in the middle of the seal 9. The seal 9 is equivalent to the bottom cover of the simulated oil tank 2, and the e-liquid in the simulated oil tank 2 flows out from the oil outlet 91 in the middle of this bottom cover and flows towards the atomizer 7; Please refer to Figure 4 , an e-liquid discharge port 92 is also arranged on the seal 9, and a third valve 14 is arranged on the e-liquid discharge port 92. By opening the third valve 14, the e-liquid in the simulated oil tank 2 can be discharged from the e-liquid discharge port 92, and the third valve 14 can control the quantitative discharge of the e-liquid or directly empty the simulated oil tank 2.

[0058] Please refer to Figure 5 , as an implementation method, a carrier platform 10 can also be detachably installed on the seal 9, and the above-mentioned atomizer fixing structure 5 is arranged on the side of the carrier platform 10 facing the observation and recording device 6; a test atomizer 7 is detachably installed on the side of the carrier platform 10 facing the observation and recording device 6, and an oil inlet 101 is arranged on the opposite side (see Figure 4), the fuel inlet 101 penetrates through both sides of the carrier 10 and is connected to the atomization core 7; the fuel inlet 101 is also connected to the oil outlet 91 on the seal 9. After the e-liquid in the simulated oil tank 2 flows out from the oil outlet 91 in the middle of the seal 9, it enters the fuel inlet 101 of the carrier 10 and then flows to the atomization core 7. Please refer to Figure 6 , to prevent oil leakage between the carrier 10 and the seal 9, a sealing material 11, such as felt, can also be clamped between the carrier 10 and the seal 9; a central hole avoiding the fuel inlet 101 is provided on the sealing material 11, and the central hole prevents the sealing material 11 from blocking the fuel inlet 101.

[0059] Please refer to Figure 7 , further, a platform base 15, a platform bracket 16 and a platform plate 17 can be adopted. The guide rail 8 for moving the driving observation and recording device 6 is fixed on the platform base 15, and the platform bracket 16 is also fixed on the platform base 15.

A plurality of channels are opened on the connecting block 18. One end of all the channels leads to the inside of the simulated oil tank 2, and the other ends of the respective channels are respectively connected to a piston air cylinder 31, a pressure gauge 4, a first valve 12 and a water pipe 32. A downward convex sealing plug (see Figure 3 ) that is inserted into the top inside the simulated oil tank 2 is provided on the lower surface of the connecting block 18.

The detachable connection manner between the carrier 10 and the seal 9 is, for example: screws are provided on the lower surface of the carrier 10, and the screws pass through the carrier 10 and are screwed to the seal 9; or studs are provided on the outside of the circular groove 94 of the seal 9, and the studs penetrate into the circular groove 94 and abut against the side wall of the carrier 10.

One end of the pressing piece 19 is detachably connected to the carrier table 10 by a screw, and the other end presses on the edge of the atomization core 7 in the slot 102; when the pressing piece 19 is made of a metal material, the pressing piece 19 can be used as an electrode; the end of the pressing piece 19 pressing on the atomization core 7 has elasticity, and a tool can be used to lift this end to take out the atomization core 7 from the slot 102, or directly loosen the screw to remove the pressing piece 19 and then take out the atomization core.
