[0042] In a first aspect, the embodiments of the present application disclose a cold trap capturing device, comprising: a container 110 having a first containing space 113, the bottom of the container 110 has a collection groove 1121 embedded towards the first containing space 113; a base 130, the base 130 is arranged at the bottom of the container 110 and is used to support the container 110, the base 130 and the container 110 jointly define a containing cavity 131, the containing cavity 131 communicates with the collection groove 1121; the containing cavity 131 is used to place an aerosol generating unit 300, and the collection groove 1121 is configured to cool the aerosol generated by the aerosol generating unit 300 and capture the condensed liquid after condensation.

[0043] In the embodiments of the present application, the first containing space 113 of the container 110 is filled with a cooling medium, so that the internal temperature of the container 110 can be equivalent to that of the cooling medium, and the container 110 acts as a cold trap trapping device, so that the structure of the cold trap trapping device is simple and convenient for users to use. Since the bottom of the container 110 has a collection groove 1121 embedded towards the first containing space 113, and the base 130 is arranged at the bottom of the container 110, and the base 130 and the container 110 jointly define a containing cavity 131 in communication with the collection groove 1121, the aerosol generating unit 300 can be placed below the collection groove 1121 through the containing cavity 131, and the aerosol generated by the aerosol generating unit 300 can be condensed into condensed liquid and attached to the groove wall of the collection groove 1121 after being condensed into condensed liquid, so that the aerosol can be fully captured and the capture efficiency is high. In addition, the cold trap trapping device can be used in cooperation with the Cambridge trapping device to classify and collect the aerosol generated by the aerosol generating unit, so as to ensure the accuracy of the experimental data of the test sample.

[0044] In the embodiments of the present application, the cold trap trapping device can be used to collect the condensed liquid formed after the aerosol is condensed, and by testing the condensed liquid using an instrument, the composition and toxicity of the aerosol can be researched and analyzed. The cold trap trapping device includes a container 110, which can have a first containing space 113. The first containing space 113 can be used to fill a cooling medium to cool the container 110, so that the container 110 can achieve the effect of a simple cold trap trapping device and facilitate the collection of aerosol. The cooling medium can be dry ice, liquid nitrogen or ice cubes, etc.

[0045] In some embodiments, the container 110 can be provided with a first opening 1111, which can be in communication with the first containing space 113, so as to facilitate the filling of the cooling medium into the first containing space 113 through the first opening 1111.

[0046] In some embodiments, the cold trap trapping device includes a sealing cover 120, which can be arranged on the first opening 1111 to ensure that the temperature in the first containing space 113 can be maintained for a long time, which is beneficial to improve the trapping effect of the aerosol.

[0047] In some embodiments, the sealing cover 120 can be movably connected to the container 110, so as to realize the opening and closing of the first opening 1111 of the container 110 through the sealing cover 120; or the sealing cover 120 can also be detachably connected to the container 110, so as to realize the opening and closing of the first opening 1111 of the container 110 through the sealing cover 120.

[0048] For example, when the temperature of dry ice is -78℃, the sealing cover 120 is opened, and the dry ice is filled into the first accommodating space 113 through the first opening 1111. After the first opening 1111 is sealed by the sealing cover 120, the temperature inside the container 110 can be equivalent to the temperature of the dry ice after 10 minutes of standing, so that the container 110 can achieve the effect of a simple cold trap trapping device.

[0049] In some embodiments, the container 110 can be a transparent structure to facilitate observation of the inside of the container 110, or the container 110 can also be a non-transparent structure. The material of the container 110 can be glass or plastic, and the like, which is not specifically limited in the embodiments of the present application.

[0050] In some embodiments, the cold trap trapping device further includes a base 130 arranged at the bottom of the container 110. The base 130 can be fixedly connected with the container 110, or the base 130 can be in abutment with the container 110. The base 130 arranged at the bottom of the container 110 can support and elevate the container 110. The material of the base 130 can be the same as or different from that of the container 110. For example, the base 130 can be a plastic or glass structure with rigidity, and the like.

[0051] In some embodiments, the base 130 can be provided with an avoiding opening 133 in communication with the accommodating cavity 131, for avoiding the aerosol generating unit 300 to be accommodated into the accommodating cavity 131.

[0052] In the embodiments of the present application, the aerosol generating unit 300 can be placed into the accommodating cavity 131 from the avoiding opening 133, so as to place the aerosol generating unit 300 below the collecting groove 1121, so that the aerosol generated by the aerosol generating unit 300 can be collected on the groove wall of the collecting groove 1121 after being condensed into condensed liquid.

[0053] In some embodiments, the base 130 can include at least two supports 132, and the at least two supports 132 can be arranged at intervals along the circumference of the container 110. The interval of the two supports 132 in the circumferential direction of the container 110 can form the avoiding opening, and the interval of the two supports 132 in the radial direction of the container 110 can jointly define the accommodating cavity 131 with the container 110.

[0054] In some embodiments, the base 130 can be an annular member provided with a notch, and the notch can form the avoiding opening. The annular member can jointly define the accommodating cavity 131 with the container.

[0055] In some embodiments, the bottom of the container 110 can have an embedded collection groove 1121, which can be arranged outside the first containing space 113. The base 130 is arranged on the bottom of the container 110. After the container 110 is elevated by using the base 130, the space below the collection groove 1121 is jointly defined by the base 130 and the container 110 to form a containing cavity 131. The containing cavity 131 is below the collection groove 1121 and communicates with the collection groove 1121. In this way, after the aerosol generating unit 300 is placed in the containing cavity 131, the aerosol generated by the aerosol generating unit 300 can diffuse in the collection groove 1121. Because the temperature of the container 110 is relatively low, the aerosol can be condensed into condensed liquid and then attached to the groove wall of the collection groove 1121, thereby realizing the collection of the aerosol.

[0056] In some embodiments, after the aerosol generating unit 300 is combusted, the cooling medium in the container 110 can be poured out, and then the container 110 can be inverted to clean the groove wall of the collection groove 1121 and collect the condensed liquid, so as to facilitate the use of instruments to test the composition and toxicity of the condensed liquid. For example, the collection process of the condensed liquid can include using anhydrous ethanol to clean the groove wall of the collection groove 1121.

[0057] In some embodiments, the container 110 includes a first enclosing part 111, a second enclosing part 112, and a connecting part 114 connected between the first enclosing part 111 and the second enclosing part 112. The second enclosing part 112 is enclosed to form a collection groove 1121. The first enclosing part 111 is sleeved outside the second enclosing part 112 and is arranged in a spaced manner with the second enclosing part 112. The first enclosing part 111, the connecting part 114, and the second enclosing part 112 are enclosed to form a first containing space 113. The base 130 is arranged on the side of the connecting part 114 away from the second enclosing part 112. The base 130 and the connecting part 114 are enclosed to form a containing cavity 131.

[0058] In the embodiments of the present application, the container 110 is enclosed by the first enclosing part 111, the connecting part 114, and the second enclosing part 112, so that the structure of the container 110 is simple and the cost of collecting the aerosol is reduced.

[0059] In some embodiments, the container 110 is an integral structure, or the first enclosing part 111 and the connecting part 114, or the connecting part 114 and the second enclosing part 112 can also be spliced and fixed.

[0060] In some embodiments, the first enclosing part 111 can be open at both ends. One end forms a first opening 1111, and the other end is connected with the connecting part 114 and is blocked by the connecting part 114 and the second enclosing part 112. The first enclosing part 111 can be a straight cylinder structure, or, for example, Figure 1As shown, the size of the opening at the end where the first enclosure portion 111 connects to the connecting portion 114 is smaller than the size of the first opening 1111.

[0061] In some embodiments, the second enclosure 112 may be open at one end to facilitate the enclosure and formation of the collection groove 1121. The second enclosure 112 may be a cylindrical structure, or, as... Figure 1 As shown, the second enclosure 112 can also be a conical structure.

[0062] In some embodiments, the connecting portion 114 may be an annular plate-shaped structure connected to the same end of the first enclosure portion 111 and the second enclosure portion 112. That is, the outer periphery of the connecting portion 114 is connected to the bottom of the first enclosure portion 111, and the inner periphery is connected to the bottom of the second enclosure portion 112, so that the connecting portion 114, the first enclosure portion 111 and the second enclosure portion 112 can be enclosed to form the first accommodating space 113.

[0063] In some embodiments, the base 130 is disposed on the side of the connecting portion 114 opposite to the second enclosure portion 112, and the base 130 can enclose the connecting portion 114 to form an accommodating cavity 131. The base 130 can be used to support and elevate the connecting portion 114, so that the space below the connecting portion 114 can be defined as the accommodating cavity 131.

[0064] In some embodiments, the surface of the second enclosure 112 facing the first enclosure 111 is a conical arc surface, which facilitates uniform cooling of the tank wall of the collection tank 1121 and improves the collection effect of aerosols.

[0065] In some embodiments, the surface of the first enclosure 111 facing the second enclosure 112 is a frustum arc surface, which is adapted to the conical arc surface to facilitate control of the gap between the first enclosure 111 and the second enclosure 112, thereby controlling the amount of cooling medium filled.

[0066] In some embodiments, the opening of the collection groove 1121 is oriented directly towards the receiving cavity 131, and the depth of the collection groove 1121 is equal to or less than the depth of the first receiving space 113.

[0067] In this embodiment of the application, the depth of the collection tank 1121 is equal to or less than the depth of the first accommodating space 113, so as to ensure that the first opening 1111 is sealed by the sealing cap 120 and that the tank wall of the collection tank 1121 is cooled by the cooling medium.

[0068] like Figure 1 As shown, the opening of the collection trough 1121 faces downward and is flush with the bottom of the container 110, and the collection trough 1121 extends along the axial direction of the container 110. The center line of the first opening 1111, the center line of the collection trough 1121, and the center line of the container 110 coincide, which helps to ensure the structural stability of the container 110.

[0069] The cold trap trapping device in this application embodiment has at least the following advantages:

[0070] In this embodiment, a cooling medium is filled into the first accommodating space 113 of the container 110, so that the internal temperature of the container 110 is comparable to that of the cooling medium. The container 110 acts as a cold trap collection device, making the structure of the cold trap collection device simple and convenient for users. Since the bottom of the container has a collection groove embedded in the first accommodating space, and the base 130 is disposed at the bottom of the container 110, together with the container, they define a receiving cavity communicating with the collection groove. Thus, the aerosol generating unit 300 can be placed below the collection groove 1121 through the receiving cavity 131. The aerosols generated by the aerosol generating unit 300 are condensed into condensate and can adhere to the wall of the collection groove 1121, achieving sufficient aerosol capture with high capture efficiency. Furthermore, the cold trap collection device can be used in conjunction with a Cambridge trapping device to classify and collect the aerosols generated by the aerosol generating unit, thereby ensuring the accuracy of experimental data for test samples.

[0071] Secondly, embodiments of this application also disclose a trapping system, including an aerosol generation unit 300, which may include a combustion end and a suction end; the aforementioned cold trap trapping device 100 is disposed at the combustion end and is used to trap aerosols generated at the combustion end; the Cambridge trapping device 200 is disposed at the suction end and is used to trap aerosols generated at the suction end.

[0073] In this embodiment, the aerosol generation unit 300 is a cigarette product. Most of the aerosols generated during the combustion process of the cigarette product are emitted from the inhalation end, and some aerosols are emitted into the environment from the combustion end. The Cambridge trapping device 200 is used to trap the mainstream aerosols generated at the inhalation end, and the cold trapping device 100 can be used to trap the peripheral aerosols generated at the combustion end.

[0074] In this embodiment of the application, the collection system may further include a recovery box 270, which may be placed inside the accommodating cavity 131. The aerosol generating unit 300 may be placed above the recovery box 270, so that the recovery box 270 may be used to collect the products after the aerosol generating unit 300 has been burned.

[0075] In some embodiments, the Cambridge trap device 200 comprises a suction collection unit 210 and a connecting pipe 220; one end of the connecting pipe 220 is used to connect the aerosol generating unit 300, and the other end is connected with the suction collection unit 210; the cold trap trap device 100 is arranged above the end of the connecting pipe 220 away from the suction collection unit 210.

[0076] In the embodiments of the present application, the connecting pipe 220 is in communication with the aerosol generating unit 300 and the suction collection unit 210 respectively to flow gas. After the suction collection unit 210 starts to suck, the air pressure is transmitted to the aerosol generating unit 300 through the connecting pipe 220, and through the suction of the aerosol generating unit 300, the aerosol generating unit 300 can burn to generate aerosol.

[0078] In the embodiments of the present application, the holder 230 can transmit air pressure to the aerosol generating unit 300 through the connecting pipe 220, so as to facilitate the aerosol generating unit 300 to continuously burn to generate aerosol. Moreover, the Cambridge filter can be integrated inside the holder 230, so that the Cambridge filter can fully and comprehensively trap the mainstream aerosol generated by the aerosol generating unit 300 at the combustion end.

[0079] In some embodiments, the trap system further comprises a sealed box 240, and the cold trap trap device 100, the holder 230 and the aerosol generating unit 300 are all arranged in the sealed box 240; the connecting pipe 220 is arranged in the sealed box 240 and is sealingly connected with the sealed box 240.

[0080] In the embodiments of the present application, the cold trap trap device 100 and the aerosol generating unit 300 are both placed in the sealed box 240, which facilitates the control of the collection environment and improves the reliability of aerosol collection.

[0083] In some embodiments, the upper portion of the sealed box 240 is provided with a gas exchanger 250, the gas exchanger 250 is provided with a vent 251, the vent 251 communicates the inside of the sealed box 240 with the outside; the gas exchanger 250 is filled with dry materials.

[0084] In the embodiment of the present application, the gas exchanger 250 can communicate the inside of the sealed box 240 with the outside through the vent 251, so as to facilitate the supplement of gas into the sealed box 240 through the vent 251, to ensure the smooth and complete combustion of the aerosol generating unit 300.

[0085] Moreover, the dry materials in the gas exchanger can also absorb moisture, effectively reducing the moisture in the air, avoiding the interference of the moisture in the air with the full combustion of the aerosol generating unit 300, and further improving the collection effect of the aerosol.

[0086] In the embodiment of the present application, the gas exchanger 250 can be a filter box, facilitating the storage of dry materials, and the gas exchanger 250 and the sealed box 240 can be communicated through a filter screen, which can ventilate and also prevent the dry materials from leaking.

[0087] In some embodiments, the inside of the sealed box 240 is placed with a dryer 260, and the dryer 260 is filled with dry materials.

[0093] Specifically, the cover 242 can be provided with a handle 243, so as to improve the convenience of opening or closing the second opening 2411.

[0094] In the embodiment of the present application, the collection process of the collection system includes: before the suction collection unit 210 starts to suck, dry materials such as molecular sieve or water-absorbing sponge are added into the gas exchanger 250 and the dryer 260, and after the container 110 is filled with dry ice, the cold trap collection device is placed into the sealed box 240, the suction collection unit 210 and the holder 230 are connected by using the connecting pipe 220.
