Description

Technical Field

[0001] This utility model relates to the technical field of aerosol absorption devices, and in particular to an absorption and extraction device for electronic cigarette aerosols. Background Technology

[0002] With the increasing popularity of e-cigarettes, more and more research is focusing on the analysis of components and the assessment of cytotoxicity in e-cigarette aerosols. E-cigarettes generate aerosols by heating a liquid (often called e-liquid) containing nicotine, flavorings, and other chemicals, which users inhale to experience pleasure and satisfaction. However, e-cigarette aerosols may contain a range of potentially harmful components, including volatile organic compounds (VOCs) and heavy metal ions. To accurately analyze these components, researchers need an effective method to capture e-cigarette aerosols. Traditional aerosol sampling methods involve capturing aerosols using Cambridge filter pads (CFPs) or absorbent liquids, which have certain limitations, such as low aerosol capture efficiency and the need to introduce additional extraction solvents. Therefore, developing a device capable of efficiently absorbing and separating e-cigarette aerosols is of great significance for the component analysis and cytotoxicity assessment of e-cigarette aerosols. Utility Model Content

[0003] The present invention aims to provide an absorption and extraction device for electronic cigarette aerosols, in order to solve the problems of low aerosol collection efficiency and the need to introduce additional extraction solvents in the electronic cigarette aerosol collection methods proposed in the background art.

[0004] Specifically, this utility model discloses an absorption and extraction device for electronic cigarette aerosols, the technical solution of which is as follows:

[0005] An absorption and extraction device for electronic cigarette aerosol is characterized in that it includes a connecting device (1), an absorption device (2), and an extraction device (3); wherein the connecting device (1) connects the electronic cigarette mouthpiece and the absorption device (2) and allows the aerosol generated during the inhalation of the electronic cigarette to smoothly enter the absorption device (2); the extraction device (3) separates the condensate formed by the aerosol from the absorption medium (202).

[0006] Furthermore, the connecting device (1) includes a cavity (101), an air inlet pipe (102), and a circular perforated plate (103). The air inlet pipe (102) is installed at one end of the cavity (101) for connecting to the electronic cigarette mouthpiece, and the circular perforated plate (103) is installed inside the other end of the cavity (101) to allow aerosol to enter the absorption device through the cavity, while blocking the absorption medium (202) from entering the cavity (101).

[0007] Furthermore, the absorption device (2) functions to capture aerosols and form condensate, while simultaneously storing the condensate in the absorption medium (202). The absorption device (2) includes an absorption tube (201) and an absorption medium (202). One end of the absorption tube can be sealed to the connecting device (1), and the other end is connected to the automatic smoking machine through a silicone tube. The absorption medium (202) is installed inside the absorption tube (201) to absorb aerosols and store the generated condensate. The aerosols generated after the electronic cigarette is inhaled enter the absorption tube (201) and form condensate on the absorption medium (202). At the same time, the condensate is adsorbed and stored in the pores of the absorption medium (202).

[0008] Furthermore, the extraction device (3) is installed outside the absorption device (2) to separate the condensate formed by the aerosol from the absorption medium (202). The extraction device (3) includes a centrifuge tube (301) and two annular fixing plates (302). The two annular fixing plates (302) can be installed at both ends of the outer side of the absorption tube (201) to fix it when the absorption device (2) is placed into the centrifuge tube (301). After the absorption device (2) is placed into the extraction device (3), the condensate can be separated from the absorption medium (202) by using a centrifuge. The condensate can be used for subsequent analysis and testing.

[0009] Optionally, the cavity (101) is made of either borosilicate glass or polypropylene plastic.

[0010] Optionally, the air intake pipe (102) is made of either food-grade plastic or silicone material.

[0011] Preferably, the circular perforated plate (103) is made of polypropylene plastic.

[0012] Optionally, the absorption tube (201) is made of either borosilicate glass or polypropylene plastic.

[0013] Optionally, the absorbent medium (202) is made of quartz wool, and the quartz wool has a diameter of 2-10 micrometers.

[0014] Preferably, the annular fixing piece (302) is made of polypropylene plastic, and the inner diameter of the annular fixing piece is the same as the outer diameter of the annular protrusion on the outer wall of the absorption tube (201), and the outer diameter of the annular fixing piece is the same as the inner diameter of the centrifuge tube (301).

[0015] Compared with the prior art, this utility model has the following advantages:

[0016] (1) Traditional Cambridge filters or absorbents have a low capture rate when capturing aerosols, but this device can significantly improve the capture rate.

[0017] (2) After using this device to capture aerosols, no additional solvent extraction is required during the extraction process. The composition of the condensate obtained after centrifugation is the same as that of the aerosols, which facilitates subsequent detection and experimental operations. Attached Figure Description

[0025] like Figure 1-3As shown, one embodiment of this utility model is a temperature-controlled nicotine salt synthesis device, which includes a connecting device 1, an absorption device 2, and an extraction device 3.

[0026] The connecting device 1 connects the electronic cigarette mouthpiece and the absorption device 2, allowing the aerosol generated during electronic cigarette inhalation to smoothly enter the absorption device 2. The connecting device 1 includes a cavity 101, an air inlet pipe 102, and a circular perforated plate 103. The cavity 101 is made of polypropylene, the air inlet pipe 102 is made of silicone, and the perforated plate is made of polypropylene. The air inlet pipe 102 is installed at one end of the cavity 101 for connecting the electronic cigarette mouthpiece, and the circular perforated plate 103 is installed inside the other end of the cavity 101, allowing the aerosol to pass through the cavity into the absorption device while simultaneously preventing the absorption medium 202 from entering the cavity 101.

[0027] The function of the absorption device 2 is to capture aerosols and form condensate, while simultaneously storing the condensate in the absorption medium 202. The absorption device 2 includes an absorption tube 201 and an absorption medium 202. The absorption tube 201 is made of polypropylene, and the absorption medium 202 is made of quartz wool (4 micrometers in diameter). One end of the absorption tube can be sealed to the connecting device 1, and the other end is connected to the automatic cigarette smoker via a silicone tube. The absorption medium 202 is installed inside the absorption tube 201 to absorb aerosols and store the generated condensate. Annular protrusions are provided at both ends of the outer wall of the absorption tube 201 for mounting annular fixing plates 302. The aerosols generated after inhalation of the electronic cigarette enter the absorption tube 201, forming condensate on the absorption medium 202, which is then adsorbed and stored in the pores of the absorption medium 202.

[0028] The extraction device 3 separates the condensate from the absorption medium 202. It includes a centrifuge tube 301 and two annular fixing plates 302.

The condensate can be used for subsequent analysis and testing.

[0029] Specific operation: Take 0.5g of quartz wool as the absorption medium 202 and put it into the absorption tube 201 to form the absorption device 2. Before starting the inhalation, accurately measure and record the mass of the electronic cigarette, the absorption device 2, and the centrifuge tube 301. Connect the electronic cigarette mouthpiece to the air inlet tube 102, seal one end of the cavity 101 to one end of the absorption tube 201, and connect the other end of the absorption tube 201 to the automatic inhalation machine to form a complete aerosol absorption device.
