[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this invention. Obviously, the described embodiments are one embodiment of this invention, and not all embodiments.

[0025] Unless otherwise defined, the technical or scientific terms used in this invention shall have the ordinary meaning as understood by one of ordinary skill in the art to which this invention pertains.

[0026] This embodiment provides an electronic cigarette smoking machine 10 with smoke capture function. Figure 1 This is a first-view (side front) structural schematic diagram of an electronic cigarette smoking machine 10 with smoke capture according to some embodiments of this application; Figure 2 This is a second-view (rear-side) structural schematic diagram of an electronic cigarette smoking machine 10 with smoke capture according to some embodiments of this application; Figure 3 yes Figure 2 The view shown is a schematic diagram with some structures hidden. Figure 4 This is a schematic diagram of the structure of an electronic cigarette holding device 100 of an electronic cigarette smoking machine 10 with smoke capture according to some embodiments of this application; Figure 5 This is a schematic diagram of the suction unit of an electronic cigarette smoking machine 10 with smoke collection according to some embodiments of this application; Figure 6 yes Figure 5 A schematic enlarged view of region A shown; Figure 7 This is a cross-sectional view of the suction unit of an electronic cigarette smoking machine 10 with smoke capture according to some embodiments of this application.

[0027] The electronic cigarette smoking machine 10 with smoke collection includes an electronic cigarette holding device 100, a suction unit, and a collection device.

[0028] The electronic cigarette clamping device 100 is used to clamp the electronic cigarette 170. The inhalation unit is connected to the electronic cigarette 170 clamped by the electronic cigarette clamping device 100 via a connecting tube 200, and is used to draw the smoke generated by the electronic cigarette 170 through the connecting tube 200 to the inhalation unit. The collection device is connected to the connecting tube 200 and is used to collect some components in the smoke.

[0029] The electronic cigarette smoking machine 10 with smoke capture provided in this embodiment can capture some components in the smoke generated by the electronic cigarette 170 through the capture device, thereby facilitating the testing and analysis of the hazards and components of the electronic cigarette 170.

[0030] The collection device may include a first liquid collection trap 310, a second liquid collection trap 320, and a particulate matter collector 330.

[0031] A first liquid trap 310 is connected to the connecting pipe 200 at a first position and is used to trap a portion of the liquid in the flue gas. A second liquid trap 320 is connected to the connecting pipe 200 at a second position and is used to trap another portion of the liquid in the flue gas. A particulate matter trap 330 is connected to the connecting pipe 200 at a third position and is used to trap particulate matter in the flue gas.

[0032] Experiments revealed that a single liquid trap was insufficient to adequately capture liquid from the smoke; therefore, two liquid traps were installed. Furthermore, this trapping device can capture not only liquid from the smoke but also particulate matter, facilitating comprehensive testing and analysis of the hazards and composition of the e-cigarette 170.

[0033] In some embodiments, the second position is located downstream of the first position in the direction of smoke flow, and the third position is located downstream of the second position in the direction of smoke flow. Thus, this electronic cigarette smoker 10 with smoke capture meets international standards.

[0034] The electronic cigarette smoke extractor 10 with smoke collection function may further include a detection tube 400, which is connected to the connecting tube 200 at the fourth position. The detection tube 400 is used to connect a negative pressure sensor, which is used to detect the resistance when the suction unit draws in the smoke. The detection tube 400 and the connecting tube 200 can be connected via a T-junction.

[0035] In some embodiments, the fourth position is located upstream of the first position in the direction of smoke flow. This positioning brings the negative pressure sensor closer to the electronic cigarette 170, resulting in more accurate detection. If the fourth position were located downstream of the first position in the direction of smoke flow, the detected negative pressure would be affected by the resistance of the front-end tubing, leading to inaccurate results.

[0036] The electronic cigarette smoking machine 10 with smoke collection function includes a smoking machine body 500, which is used to install the suction unit and the collection device. The electronic cigarette clamping device 100 includes: a fixed base 110, a tilting shaft 130, a tilting adjuster 140, and a clamping component.

[0037] A fixed base 110 is fixed to the main body 500 of the smoking machine, and a tilt scale component 120 is fixedly connected to the fixed base 110. The tilt scale component 120 has a rotating hole. A tilt shaft 130 is rotatably disposed in the rotating hole. A tilt adjuster 140 is fixedly connected to the tilt shaft 130. A clamping member is fixedly connected to the tilt adjuster 140 and is used to clamp the electronic cigarette 170. The clamping member drives the electronic cigarette 170 to rotate through the rotation of the tilt shaft 130; and the tilt scale component 120 is provided with an angle value for indicating the rotation angle of the electronic cigarette 170. This facilitates the adjustment of the angle of the electronic cigarette 170, thereby facilitating the testing of the tilt angle at which the e-liquid of the electronic cigarette 170 can be completely consumed.

[0038] The electronic cigarette clamping device 100 may further include a locking handle 160, which is configured to have a released state in which the tilting shaft 130 is rotatable relative to the rotating hole, and a locked state in which the tilting shaft 130 is fixed relative to the rotating hole. For example, the locking handle 160 can be rotated to press the tilting shaft 130 against the side wall of the rotating hole to achieve the locked state, and the locking handle 160 can be rotated to release the tilting shaft 130 from the side wall of the rotating hole to achieve the released state. It is understood that the locking handle 160 can also achieve these two states in other ways, which will not be elaborated here.

[0039] The holding component may include a placement portion 151, a holding portion 152, and a tension spring 153. The placement portion 151 is fixed to the tilt adjuster 140, defining an electronic cigarette slot for placing the electronic cigarette 170. The holding portion 152 is rotatably connected to the placement portion 151 via a pivot, and the holding portion 152 is provided with a first holding block and a second holding block for holding the electronic cigarette 170. The tension spring 153 connects the placement portion 151 and the holding portion 152, providing a clamping force for the first and second holding blocks to hold the electronic cigarette 170. This method not only firmly holds the electronic cigarette 170 but also allows for quick disassembly, improving the user experience.

[0040] The electronic cigarette vaping device 10 with smoke collection function may further include a sealing connector 600 and a connector 700. One end of the sealing connector 600 is used to connect to the electronic cigarette 170. One end of the connector 700 is used to connect to the other end of the sealing connector 600, and the other end of the connector 700 is used to connect to the connecting tube 200. This satisfies the sealing requirements during inhalation and ensures the accuracy of the test results.

[0041] In some embodiments, the connector 700 is a reducing connector, which is used to connect sealing connectors 600 of different sizes. The reducing connector, in conjunction with sealing connectors 600 of different diameters, can accommodate electronic cigarettes 170 of different sizes and meet the sealing requirements of electronic cigarettes 170 of different shapes.

[0042] The main body 500 of the smoking machine may include an upper housing 850 and a lower housing 860, which define a receiving cavity. Multiple support columns 880 (e.g., four) are provided within the receiving cavity. Support plates 890 are supported by the support columns 880. An electrical board 891 is located below the support columns 880, and a control unit is installed on the electrical board 891 to control the operation of the electronic cigarette smoking machine 10 with smoke collection. Suction units (multiple suction units may be horizontally arranged side-by-side on the support plate 890) are supported on the support plate 890. The receiving cavity may have a rear opening, at which a maintenance plate 892 is detachably provided for easy maintenance of the components within the receiving cavity.

[0043] Understandably, there can be multiple suction units (e.g., 10). Correspondingly, there can also be multiple electronic cigarette clamping devices 100, connecting tubes 200, collecting devices, detection tubes 400, etc. That is, the electronic cigarette smoke extractor 10 with smoke collection can be a multi-channel electronic cigarette smoke extractor with smoke collection. The exhaust pipes of all suction units can be connected to the gas collector 870 set in the receiving cavity, and the smoke is discharged from the exhaust port 840 on the main body after passing through the gas collector 870.

[0044] In some embodiments, the main body 500 of the smoking machine may also be provided with a display panel 810, which is used to set parameters and display the operating status. For example, by setting parameters such as suction capacity, suction time, suction cycle, and number of puffs, the ten channels of electronic cigarettes 170 can be cyclically inhaled synchronously or asynchronously. The multi-channel electronic cigarette smoking machine with smoke capture provided in this embodiment can be used to test the continuous number of puffs of electronic cigarette 170 cartridges, the lifespan of electronic cigarette 170, and the draw resistance of electronic cigarette 170. It can also be connected to an electronic cigarette trap or filter membrane trap to collect smoke components, or used as an electronic cigarette generator for electronic cigarette animal experiments, etc.

[0045] The main body 500 of the smoking machine may be equipped with a buzzer 820 for fault alarm and operation prompt, and an emergency stop switch 830. The main body 500 of the smoking machine may also be provided with a heat dissipation vent 893, a communication port 894, and a power port 895. A fan is provided at the position corresponding to the heat dissipation vent 893 to achieve heat dissipation of the electronic cigarette smoking machine 10 with smoke capture.

[0046] The suction unit can be a quick-release suction piston device 900 with a connecting rod, including a main body 910, a cylinder 920, a connecting rod seat 930, a wrench 940, and an end cap 950. One end of the cylinder 920 is connected to the main body 910, and the cylinder 920 defines a cavity. A piston 921, which can move along the axial direction of the cylinder 920, is disposed in the cavity. The movement of the piston 921 is used to achieve the suction of flue gas in the cavity. The connecting rod seat 930 is fixed to the main body 910 and is used to install the rotating shaft 931. The wrench 940 is rotatably disposed on the rotating shaft 931, and the wrench 940 is provided with a tensioning shaft 941, which fixes one end of a tensioning rope 942. The end cap 950 is connected to the other end of the tension rope 942 and is configured to have an installed state in which the cylinder 920 is clamped together with the body 910 by the rotation of the wrench 940 around the rotation axis 931, and a disassembled state in which the clamping of the cylinder 920 is released.

[0047] The quick-release and detachable suction piston device 900 and electronic cigarette smoke machine provided in this embodiment can suck up the smoke generated by electronic cigarettes. It is easy to install and disassemble, can be quickly disassembled, is easy to use, and has a compact structure, making installation and maintenance convenient.

[0048] Specifically, in some embodiments, the handle can be a Y-shaped structure, specifically including two parallel handle arms and a handle portion connected to one end of each of the two handle arms. Each handle arm is used to connect to a rotating shaft 931, and the portion of the handle arm near the handle portion has an opening for mounting a tensioning shaft 941. An end cap 950 has an end cap hole for mounting the other end of a tensioning rope 942, and the end cap 950 hole has a stop portion to prevent the tensioning rope 942 from detaching from the end near the cylinder 920, allowing the tensioning rope 942 to detach from the end away from the cylinder 920.

[0049] The quick-release suction piston device 900 may further include a lead screw nut 961, a lead screw 962, and a motor 963. The lead screw nut 961 is fixedly connected to the end of the piston 921 facing away from the end cover 950. The lead screw 962 is used to mount the lead screw nut 961. The motor 963 is connected to the lead screw 962 and drives the lead screw 962 to rotate, thereby moving the lead screw nut 961, and subsequently moving the piston 921 along the axial direction of the cylinder 920. The motor 963 and the lead screw 962 can be connected via a coupling 964. This driving method is stable, reliable, and has a simple structure.

[0050] In some embodiments, the main body 910 has an opening extending along the axial direction of the cylindrical cavity, and the lead screw 962 is disposed within the opening of the main body 910, with the lead screw nut 961 configured to move within the opening of the main body 910. This not only saves space but also facilitates the protection of other components by the main body 910.

[0051] The quick-release suction piston device 900 may further include an anti-rotation slider 971 and an anti-rotation component 972. One end of the anti-rotation slider 971 is fixedly connected to the lead screw nut 961. The anti-rotation component 972 is installed on the main body 910 and has an anti-rotation groove extending along the axial direction of the cylindrical cavity. The other end of the anti-rotation slider 971 is located within the anti-rotation groove. This prevents the lead screw nut 961 from rotating circumferentially, thereby avoiding rotational movement of the piston 921 and ensuring the overall stability and sealing effect of the device.

[0052] The quick-release and detachable suction piston device 900 may also include a zero-position sensor 973, which is fixed to the anti-rotation component 972 and is used to detect whether the piston 921 is in a preset position. This ensures the consistency of experimental and test results.

[0053] The quick-release suction piston device 900 may further include an intake pipe 981, an exhaust pipe 982, and a solenoid valve 983. The intake pipe 981 is connected to the end cap 950 and communicates with the cylindrical cavity through the end cap 950. The exhaust pipe 982 is connected to the end cap 950 and communicates with the cylindrical cavity through the end cap 950. The solenoid valve 983 is connected to both the intake pipe 981 and the exhaust pipe 982 and is configured to have an intake state where the gas flow path of the intake pipe 981 is open and the gas flow path of the exhaust pipe 982 is closed, and an exhaust state where the gas flow path of the exhaust pipe 982 is open and the gas flow path of the intake pipe 981 is closed. This configuration of the solenoid valve 983 makes overall operation convenient and highly automated.

[0054] The quick-release suction piston device 900 may further include a first seal 991 and a second seal 992. The first seal 991 is installed on the piston 921, and the piston 921 is connected to the inner wall of the cylinder 920 via the seal. The second seal 992 is installed on the end cap 950, and when the end cap 950 is in the installed state, it is connected to the cylinder 920 via the second seal 992. This ensures the overall sealing of the device.

[0055] In this embodiment, when the quick-release suction piston device 900 is working, the motor 963 operates, thereby driving the lead screw 962 to rotate. The lead screw nut 961 then slides on the lead screw 962. Under the action of the anti-rotation slider 971 and the anti-rotation component 972, the lead screw nut 961 does not perform circular motion, but only linear motion. Consequently, the piston 921 performs linear motion. During this motion, the zero-position sensor 973 can control the movement distance for the mechanism to return to zero. For disassembly, the wrench 940 is rotated towards the end cover 950, and the tension shaft 941 moves accordingly. At this time, the tension rope 942 changes from a taut state to a slack state, and the cylinder 920 is no longer clamped between the end cover 950 and the main body 910, allowing for quick disassembly. During installation, rotate the wrench 940 away from the end cover 950. The tension shaft 941 moves accordingly, and the tension rope 942 changes from a slack state to a taut state. The end cover 950 and the main body 910 clamp the cylinder 920. When the wrench 940 is in contact with the main body 910, the tension of the tension rope 942 does not have a component force that causes the wrench 940 to rotate. The linkage mechanism formed by the wrench 940 and others is in a dead position, realizing the mechanism self-locking, thereby achieving quick installation.

[0056] In this embodiment, the electronic cigarette smoke extractor 10 with smoke capture function operates with the solenoid valve 983 in the suction state, and the suction unit provides negative pressure suction to simulate the human body inhaling the electronic cigarette 170. During inhalation, the piston 921 moves towards the motor 963, generating suction. Smoke is generated from the electronic cigarette 170, passes through two liquid traps, then through the particulate matter trap 330, and is drawn into the cylinder 920 through the suction pipe 981. During exhaust, the solenoid valve 983 switches, the suction pipe 981 closes, the exhaust pipe 982 opens, the piston 921 moves in the opposite direction, and the smoke enters the gas collector 870 through the exhaust pipe 982 and is discharged from the exhaust port 840. This embodiment of the electronic cigarette smoke extractor 10 with smoke capture function is not only compact and flexible in use, but also features multi-channel operation, high efficiency, and high reliability.

[0057] Regarding the embodiments of the present invention, it should also be noted that, without conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other to obtain new embodiments.

[0058] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. The scope of protection of the present invention should be determined by the scope of the claims.
