[0028] Please refer to Figure 1 and Figure 2 , Figure 1 is a schematic diagram of the overall structure of a fumigation test device in some embodiments of the present application, Figure 2 is Figure 1 a schematic explosion diagram of the fumigation test device in the embodiments. The present embodiment provides a fumigation test device for testing the appliance materials of an electronic atomizer 32, including a working cabinet 10, a control mechanism 20, and a suction mechanism 30. Among them,

[0029] The working cabinet 10 has an inner cavity 101, and a fumigation table 11 is arranged in the inner cavity 101 of the working cabinet 10. The fumigation table 11 is used for placing samples. A cabinet door 12 is hingedly arranged on the working cabinet 10. By rotating the cabinet door 12, the working cabinet 10 can be closed or opened to facilitate the taking and placing of samples. A sealing ring can be arranged on the periphery of the cabinet door 12 to improve the sealing performance of the working cabinet 10.

[0030] The suction mechanism 30 includes an atomizer 32 and a suction assembly 33. The atomizer 32 is used to heat the aerosol matrix and generate aerosol. The suction assembly 33 is connected to the air outlet 321 of the atomizer 32 and the inner cavity 101 of the working cabinet 10, and is used to simulate the effects of human inhalation and exhalation and transport the aerosol generated by the atomizer 32 into the inner cavity 101 of the working cabinet 10. The suction assembly 33 includes a suction pump 331. The suction pump 331 is a vacuum pump. The specific structure and working principle of the vacuum pump are technologies familiar to those skilled in the art and will not be elaborated here. The intake end of the suction pump 331 is connected to the air outlet 321 of the atomizer 32 through an intake pipe 332, and the outlet end of the suction pump 331 is connected to the inner cavity of the working cabinet 10 through an outlet pipe 333. The suction assembly 33 is electrically connected to the control mechanism 20. The control mechanism 20 is used to control the suction assembly 33 to suck the atomizer 32 and transport the aerosol generated by the atomizer 32 into the inner cavity of the working cabinet at a preset frequency. The control mechanism 20 can control the start and stop of the suction assembly 33 and control the suction interval and the number of suction cycles at a preset frequency, so as to effectively simulate the effects of human inhalation and exhalation. The preset frequency range is to suck for 2 - 5 seconds, stop for 18 - 45 seconds, and cycle for 120 - 300 times. Among them, the ratio of the suction interval duration is 1:9, and the number of cycles can be determined according to the aerosol matrix content in different types of atomizers 32. For example, the preset frequency can be to suck for 2 seconds and stop for 18 seconds, and cycle for 300 times; or suck for 3 seconds and stop for 27 seconds, and cycle for 200 times; or suck for 5 seconds and stop for 45 seconds, and cycle for 120 times, which will not be listed here.

[0031] With the above solution, during the test, the sample is placed on the fumigation table 11 of the working cabinet 10. The suction assembly 33 in the suction mechanism 30 simulates the effects of human inhalation and exhalation and transports the aerosol generated by the atomizer 32 into the inner cavity 101 of the working cabinet 10, effectively simulating the test environment of e-cigarette appliance materials in the aerosol fumigation environment.

[0032] In some embodiments, a temperature control mechanism 40 is further disposed in the inner cavity 101 of the work cabinet 10. The temperature control mechanism 40 is electrically connected to the control mechanism 20, and the control mechanism 20 can control the temperature of the inner cavity 101 to remain constant according to a preset temperature. The preset temperature range is 50-70°C, specifically it can be 50°C, 55°C, 60°C, 70°C, etc., which will not be listed one by one here. The temperature control mechanism 40 includes a heating sheet and a temperature sensor disposed in the work cabinet 10. The temperature sensor can monitor the internal temperature change of the work cabinet 10 during the fumigation test and send a first signal to the control mechanism 20, and then control the heating sheet to work through the control mechanism 20 to keep the temperature of the inner cavity at the preset temperature. In particular, the heating sheet in the temperature control mechanism 40 is made of copper-nickel alloy (Cu-Ni Alloy) and is encapsulated with polyimide (PI) to ensure high efficiency and high reliability. The temperature sensor uses an NTC thermistor, and the thermistor is made of platinum material, which has good temperature sensitivity and stability.

[0033] In some embodiments, the fumigation table 11 includes a top plate 111, a bottom plate 112 and a side plate 113. The top plate 111, the bottom plate 112 and the side plate 113 enclose to form an air chamber 114. A plurality of through holes are provided on the top plate 111, and the air outlet pipe 333 passes through the bottom plate 112 and communicates with the air chamber 114. The aerosol reaches the air chamber 114 of the fumigation table 11 via the air inlet pipe 332 and the air outlet pipe 333 under the action of the suction pump 331. The top plate 111 of the fumigation table 11 has a planar structure with a large area, which can disperse the aerosol evenly, ensure sufficient contact between the sample and the aerosol, and improve the simulation effect of the fumigation environment.

[0034] Please refer to Figure 2, in some embodiments, the suction mechanism 30 further includes a suction platform 31. An installation cavity 315 is provided inside the suction platform 31. The atomizer 32 is installed on the suction platform 31, and the suction assembly 33 is disposed inside the installation cavity 315. The suction platform 31 includes a support plate 311. The support plate 311 is inclined with respect to the horizontal plane. The support plate 311 includes a first end 312 and a second end 313 which are oppositely arranged. The first end 312 is higher than the second end 313. The atomizer 32 is installed on the suction platform 31, and the air outlet of the atomizer 32 is close to the first end 312, that is, the axis of the atomizer 32 is inclined upward to simulate the working state of the atomizer 32 during actual use. The atomizer 32 can be directly placed obliquely on the support plate 311, and the friction force between itself and the baffle 314 is used to prevent it from sliding down. The axis of the atomizer 32 is parallel to the length direction of the support plate 311. A baffle 314 is provided at the second end 313 of the support plate 311. The baffle 314 extends vertically upward. By providing the baffle 314, the atomizer 32 can be prevented from slipping from the second end 313 of the support plate 311. Of course, a snap structure can also be provided on the support plate 311 to snap and fix the atomizer 32 on the support plate 311, or the atomizer 32 can be installed and fixed by a detachable fixed connection method such as bolts and screws.

[0035] The control mechanism 20 can be a computer mainframe. For the convenience of people's operation, a display screen can also be provided to meet people's needs for consulting relevant monitoring data. In this embodiment, the control mechanism 20 includes a control main board 23. The control main board 23 is connected to a battery 24 and a power cord 25. The power cord 25 can be connected to an external power source to charge the battery 24. The control main board 23 and the battery 24 are disposed inside the installation cavity 315 of the suction platform 31 and are isolated from the atomizer 32 and the work cabinet 10 to prevent the electronic components on the control main board 23 from being damaged by the external environment. The battery 24 can supply power to the control mechanism 20, the suction assembly 33, and the temperature control mechanism 40 to ensure the normal operation of the device. It should be noted that the atomizer 32 itself includes a power supply component and a control component, and can automatically heat the aerosol matrix and generate aerosol during suction. That is to say, the atomizer 32 is an integral component, which can be independently powered and controlled. The atomizer 32 can be any electronic atomization device on the market. In this way, it is convenient to replace different atomizers 32 to test samples to detect the influence of the aerosol generated during the operation of different atomizers 32 on the appliance materials.

[0036] Further, the control mechanism 20 includes function buttons 21. The function buttons 21 are provided on the surface of the suction platform 31, specifically, they can be provided on the support plate 311. The function buttons 21 can control the operation of the device and set fumigation conditions, specifically including functions such as starting and stopping the suction assembly 33, setting the suction interval, setting the number of suction cycles, and setting the temperature.

[0037] Further, the control mechanism 20 includes a display module 22, which is located on the surface of the suction platform 31, specifically, it can be arranged on the support plate 311. The display module 22 can display the operating status of monitoring the fumigation object, and directly see the smoke in the working cabinet 10. If there is no smoke in the working cabinet 10 during the operation, it can be judged that there is no aerosol matrix in the atomizer 32 or there is a problem with the operation of the suction assembly 33, and the staff needs to immediately stop the test and inject the aerosol matrix into the atomizer 32 or monitor the equipment status; the display module 22 can also display the equipment operating status, such as the temperature data inside the working cabinet 10, the set parameters associated with the function buttons 21, etc.

[0038] Please refer to Figure 3 , Figure 3 is Figure 1 The schematic diagram of the overall structure of another perspective of the fumigation test equipment in the embodiment. In some embodiments, the fumigation test equipment includes a recovery mechanism 50, and the recovery mechanism 50 includes a condensation tank 51 and an exhaust pipe 52. One end of the exhaust pipe 52 is communicated with the inner cavity 101 of the working cabinet 10, and the other end is communicated with the condensation tank 51. Alcohol is contained in the condensation tank 51. Since electronic aerosol is usually composed of glycerol, propylene glycol, flavoring agents, and nicotine, where glycerol is the main component forming the aerosol, determining the concentration and content of the aerosol, and propylene glycol is the solvent for flavoring agents and plays an auxiliary role in forming the aerosol. Alcohol can fully absorb and dissolve compounds such as glycerol and flavoring agents in the aerosol, effectively recovering the aerosol. And using alcohol to recover the aerosol has a low cost.

[0039] In some embodiments, the working cabinet 10 is made of stainless steel or aluminum alloy materials, which have excellent strength and corrosion resistance, ensuring the cleanliness and stability of the test environment. The sealing ring of the cabinet door 12 is made of refined silicone rubber, and there is no aging or hardening phenomenon under high and low temperature conditions, ensuring reliable sealing. The gas conduits inserted at various opening positions on the working cabinet 10, such as the air outlet pipe 333 and the exhaust pipe 52, are hermetically connected to the working cabinet 10. A heat preservation layer is arranged inside the working cabinet 10, and the heat preservation layer is made of ceramic fiber heat preservation material or aerogel heat preservation material, which has excellent heat insulation performance and high temperature resistance performance, ensuring the accuracy of constant temperature control and temperature stability. The suction platform 31 is made of high-strength plastic material, which has good heat resistance and corrosion resistance, ensuring the stability of long-term use.

[0040] In this embodiment, the process of the fumigation test equipment performing a fumigation experiment is as follows:

[0041] 1. Test sample placement: Place the sample on the fumigation table 11 in the working cabinet 10.

[0042] 2. Temperature and suction parameter setting: Set the working temperature of the working cabinet 10 to 55 °C, the suction frequency is to suck for 3 seconds and stop for 27 seconds, and cycle 200 times.

[0043] 3. Start the test: Start the suction mechanism 30, simulate the human body suction process, and make the aerosol enter the inner cavity 101 of the working cabinet 10 for fumigation.

[0044] 4. End of fumigation: End the test process and shut down the equipment according to the preset test time.

[0045] The above are only some embodiments of the present application, and thus do not limit the protection scope of the present application.
