Technical Field
[0001] The present invention belongs to the technical field of electronic cigarette product detection, and particularly relates to an electronic cigarette aerosol capture device. Background Art
[0002] With the popularization of the use of electronic cigarettes, their impact on health and the environment has also attracted the attention of the public and the scientific research community. As an emerging product that replaces traditional tobacco products, electronic cigarettes have gained wide attention and use globally in recent years. Electronic cigarettes generate an inhalable aerosol by heating a liquid containing nicotine, flavors, and other chemical components (commonly referred to as "e-liquid"). This aerosol is different from the smoke generated by the combustion of traditional cigarettes and is mainly composed of tiny droplets. Research shows that the substances contained in electronic cigarette aerosols may pose potential hazards to the human respiratory system, and long-term exposure to electronic cigarette aerosols in enclosed or semi-enclosed spaces may also affect air quality. Therefore, it is crucial to capture and detect electronic cigarette aerosols to evaluate the safety of electronic cigarettes.
[0003] Currently, most traditional electronic cigarette aerosol capture devices use simple filtration mechanisms or single chemical absorption methods to capture aerosols through gas-liquid contact. However, traditional devices often rely on static chemical solutions. During the upward floating process of aerosol bubbles in the solution, the aerosol particles located within the bubble interface cannot fully contact the solution, so the solution cannot fully contact and adsorb all aerosol particles. A large number of remaining aerosol particles will directly discharge from the tank body along with the upward floating of the bubbles, resulting in poor capture effect and low efficiency. Moreover, existing electronic cigarette aerosol capture devices generally use a negative pressure suction method to directly connect to the capture tank. By pumping the air in the capture tank above the solution, the aerosol is sucked into the capture tank using negative pressure. This cannot accurately imitate the actual suction behavior of humans, causing a deviation between the capture conditions and the actual situation and affecting the validity of research results. Summary of the Invention
[0004] Aiming at the defects and problems existing in the capture of existing electronic cigarette aerosols, the present invention provides an electronic cigarette aerosol capture device. The device has a unique structure and ingenious design. By simulating the real suction process and combining physical extrusion and chemical adsorption technologies, it significantly improves the capture efficiency of aerosol particles, while ensuring simple operation and easy maintenance, so as to overcome the problems of insufficient contact and incomplete adsorption of existing devices.
[0005] The solution adopted by the present invention to solve its technical problems is as follows: An electronic cigarette aerosol capture device includes a box body, a controller, a suction seat, a suction unit, a capture unit, and a liquid supply unit. Inside the box body, a treatment chamber and a liquid drainage chamber are vertically spaced. The capture unit includes a capture tank installed in the treatment chamber. A liquid inlet hole is provided on the capture tank and is connected to the liquid supply unit. The controller can quantitatively discharge a capture solution into the capture tank through the liquid supply unit. A liquid drainage port is provided at the bottom of the capture tank, and a liquid drainage valve is installed in a matching manner. The liquid drainage end of the liquid drainage valve extends downward into the liquid drainage cavity. A storage bottle is placed in the liquid drainage cavity in a matching manner, and the liquid inlet at the top of the storage bottle is movably docked with the liquid drainage end of the liquid drainage valve. In the capture tank above the liquid drainage port, an upper filter screen and a lower filter screen are vertically spaced. A exhaust pipe group is provided in the capture tank between the two filter screens. A filter medium layer is provided in the capture tank between the exhaust pipe group and the upper filter screen. The intake end of the exhaust pipe group extends out of the capture tank and is unidirectionally communicated with the exhaust end of the suction unit. The suction seat is installed on the outer side wall of the box body in a matching manner and is unidirectionally communicated with the suction end of the suction unit.
[0006] The beneficial effects of the present invention: The electronic cigarette aerosol capture device provided by the present invention has a unique structure and ingenious design. The electronic cigarette aerosol capture device realizes efficient capture of aerosol particles through a floating body ball with an adsorption coating and an automated control system. The floating body ball forms a dynamic filter medium layer in the capture tank and floats as the liquid level of the capture liquid rises, ensuring that aerosol bubbles are squeezed and deformed or even burst when passing through, significantly increasing the contact opportunity between aerosol particles and the adsorption coating on the surface of the floating body ball, thereby greatly improving the capture efficiency. The controller coordinates the liquid supply unit, the suction unit, and the liquid drainage system to realize the full automation of the capture process (such as quantitatively supplying the capture solution and simulating real suction actions), reducing human intervention and improving the accuracy and repeatability of experimental data. In addition, the device is designed with a stirring mechanism to stir the capture liquid after suction is completed, which not only promotes the mixing of aerosol particles adsorbed on the surface of the floating body ball and the liquid, but also further improves the capture effect through the collision between the floating body balls, and prevents the floating body balls from being discharged with the liquid, maintaining the stability of the system. The liquid drainage valve and the storage bottle in the liquid drainage system ensure the safe collection of the capture liquid, facilitating the subsequent treatment and detection of the capture liquid. The electronic cigarette aerosol capture device provided by the present invention effectively improves the capture efficiency of aerosol particles, while ensuring simple operation and easy maintenance, and solves the problems of insufficient contact and incomplete adsorption of existing devices.

Detailed implementation manners
[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments. Embodiment
[0017] In view of the problems raised in the above-mentioned background art, this embodiment provides an electronic cigarette aerosol capture device, as Figure 1-6 shown, which includes a box body 1, a controller, a suction seat 2, a suction unit, a capture unit and a liquid supply unit. Inside the box body 1, a treatment chamber 11 and a drain chamber 12 are vertically spaced. There are various ways to set the treatment chamber and the drain chamber. For example, a partition is fixedly provided inside the box body, and the partition divides the internal space of the box body into an upper treatment chamber and a lower drain chamber from top to bottom.
[0018] The capture unit includes a capture tank 4 installed in the processing chamber. A bracket is provided outside the capture tank 4 for fixing the capture tank. A breathing hole is provided at the top of the capture tank 4. A liquid inlet hole is provided on the capture tank 4 and is connected to a liquid supply unit. The liquid supply unit is connected to a controller. The controller can control the liquid supply unit to quantitatively discharge a capture solution into the capture tank. The capture solution is a dilute nitric acid solution, which is formed by mixing a nitric acid solution and a diluent.
[0019] As Figure 1 and Figure 3 shown, the liquid supply unit includes a dilution tank 71, a nitric acid tank, a liquid supply pipeline, and a valve group. The dilution tank 71 stores a diluent, and the nitric acid tank stores a nitric acid solution. A safety box 72 is provided in the box body 1, and the nitric acid tank is installed in the safety box 72. The drainage ends of the dilution tank and the nitric acid tank are connected to the capture tank through the liquid supply pipeline. The valve group is installed on the liquid supply pipeline and is connected to the controller. The controller can control the discharge amounts of the diluent and the nitric acid solution by controlling the valve group; and the installation heights of both the dilution tank and the nitric acid tank are higher than the installation height of the capture tank, so that when the valve group is opened, the solutions in the dilution tank and the nitric acid tank will automatically flow into the capture tank by gravity.
[0020] Specifically: the liquid supply pipeline includes a liquid supply pipe 73 and a dilution pipe 74. The valve group includes a dilution valve 75 and a nitrate discharge valve 76 connected to the controller. The nitrate discharge valve 76 is installed at the discharge port of the nitric acid tank. One end of the liquid supply pipe is connected to the liquid inlet hole of the capture tank, and the other end is connected to the nitrate discharge valve 76; one end of the dilution pipe 74 is connected to the discharge port of the dilution tank 7, and the other end is connected to the liquid supply pipe 73; the dilution valve 75 is installed on the dilution pipe 74. During use, the controller first controls the dilution valve to open and discharges a quantitative diluent into the capture tank through the liquid supply pipe. During this process, the controller will control the nitrate discharge valve to open synchronously and discharge a quantitative nitric acid solution into the capture tank through the liquid supply pipe. When the nitric acid solution is discharged, the nitric acid solution will be mixed with the diluent, so that a dilute nitric acid solution is formed in the capture tank.
[0021] There are various ways to quantitatively discharge the nitric acid solution and the diluent. For example, liquid level gauges are provided in both the nitric acid tank and the dilution tank. The liquid level gauges are connected to the controller, and the controller controls the opening and closing of the valves according to the liquid height in the pipes, so as to achieve the purpose of accurate quantitative liquid discharge.
[0022] As Figure 5As shown, the bottom of the capture tank 4 is matched with a drain port, and a drain valve 45 is installed, the drain valve 45 is connected to the controller, the drain end of the drain valve 45 extends downward into the drain cavity, and a storage bottle 6 is placed in the drain cavity, and the top liquid inlet of the storage bottle 6 is movably connected to the drain end of the drain valve 45. Specifically: the drain end of the drain valve 45 extends downward into the drain cavity, and is installed with a drain seat 46 that matches the bottle mouth of the storage bottle. After the storage bottle 6 is placed in the drain chamber, the bottle mouth of the storage bottle can be matched and inserted into the drain seat.
[0023] Furthermore, there is a window on the outer wall of the box body connected to the drainage chamber, and a box door 13 is installed on the window. The box door 13 is an existing box door, one end of which is hingedly installed on the outer wall of the box body, and the other end is movably connected to the outer wall of the box body through a lock body. When the lock body is opened, the box door can be opened.
[0024] An upper filter screen 43 and a lower filter screen 41 are vertically spaced apart in the capture tank 4 above the discharge port, an exhaust pipe group 42 is provided in the capture tank between the two filters, a filter medium layer is provided in the capture tank between the exhaust pipe group 42 and the upper filter screen 43, an air inlet end of the exhaust pipe group 42 extends outward from the capture tank and is unidirectionally connected to the exhaust end of the suction unit, the suction seat 2 is matched and mounted on the outer side wall of the box body, and is unidirectionally connected to the suction end of the suction unit, the suction seat is used to install and connect the electronic cigarette, the suction unit is connected to the controller, and the controller can imitate the human suction action to suck the electronic cigarette through the suction unit and discharge the aerosol into the capture tank.
[0025] Specifically: Figure 1 and Figure 2 As shown, the suction seat 2 includes an upper socket 21 and a lower top platform 22. The upper socket 21 includes a socket body 211 fixedly mounted on the outer side wall of the box body. The bottom surface of the socket body 211 is matched with a cigarette holder plug 212 which is unidirectionally connected to the suction end of the suction unit. The cigarette holder plug 212 is arranged downward for inserting an electronic cigarette. The lower top platform is vertically slidably mounted on the outer side wall of the box body below the upper socket, and is matched with an elastic member. The elastic member will push the lower top platform upward in a natural state, driving the lower top platform to move upward and collide with the bottom of the electronic cigarette inserted on the cigarette holder plug.
[0026] There are many ways to install the lower top platform 22 on the outer side wall of the box body along the vertical sliding. For example, a slide groove 16 is vertically provided on the outer side wall of the box body 1, and a guide column 24 is vertically installed in the slide groove 16. A slide seat 23 is mounted on the guide column 24. The slide seat 23 can slide up and down along the guide column. The slide seat extends outward from the slide groove and is fixedly connected to the lower top platform. The elastic member is a top spring 25 matched with the guide column below the slide seat. The top spring will push the slide seat upward in a natural state to drive the lower top platform to move upward, and it will conflict with the bottom of the electronic cigarette inserted on the cigarette holder plug, thereby clamping the electronic cigarette to prevent the electronic cigarette from falling off during the capture process.
[0027] The filter medium layer includes a plurality of floating balls 44. An adsorption coating is provided outside the floating balls. The upper filter screen and the lower filter screen are used to intercept the floating balls. When the upper filter screen in the liquid discharge tank is submerged by the captured solution, the floating balls will float upward following the captured solution under the action of buoyancy and be blocked below the upper filter screen to form a filter medium layer. Thus, when the aerosol bubbles discharged from the exhaust pipe group pass through the filter medium layer during the upward floating process, the aerosol particles in the aerosol bubbles will be adsorbed on the surface of the floating balls, preventing them from rising with the aerosol bubbles and being discharged from the capture tank, which can effectively improve the capture efficiency.
[0028] In this embodiment, a suction pipe that is unidirectionally communicated with the suction end of the suction unit is matched and provided inside the socket body. The first end of the suction pipe extends downward out of the socket body and is connected to the top end of the plug.
[0029] The suction unit includes an outer cylinder body 31 with an open top end and a reciprocating drive assembly. The outer cylinder body 31 is fixedly installed on the inner side wall of the box body on one side of the capture tank. An exhaust hole and a suction hole that are communicated with the inside of the cylinder body are matched and provided at the bottom of the outer cylinder body 31. A one-way suction valve 38 is matched and installed on the suction hole. The suction end of the one-way suction valve is communicated with the cigarette mouth plug. The intake end of the exhaust pipe group extends out of the capture tank and a one-way intake valve 39 is matched and installed. The intake end of the one-way intake valve is connected to the exhaust hole at the bottom of the outer cylinder body through a pipe.
[0030] A suction piston 32 is matched and installed inside the outer cylinder body 31. A drive piston 33 is matched and installed inside the outer cylinder body above the suction piston 2. The drive piston and the suction piston are fixedly connected together through a connecting rod 34. The reciprocating drive assembly is matched and installed on the box body above the outer cylinder body and is in transmission connection with the drive piston. The controller can drive the drive piston to drive the suction piston to move up and down reciprocally through the reciprocating drive assembly. When the suction piston moves upward, it will imitate the suction action of a person to suck the electronic cigarette installed on the suction seat, and suck the aerosol generated by the electronic cigarette into the outer cylinder body through the one-way suction valve. When the suction piston moves downward, it will discharge the aerosol sucked into the outer cylinder body into the capture tank through the one-way intake valve and the exhaust pipe group.
[0031] The reciprocating drive assembly includes a drive motor 37 fixedly installed on the outer side wall of the box body. The drive motor 37 is connected to the controller. The motor rotating shaft of the drive motor 37 extends into the relevant body and a connecting rod 36 is fixedly sleeved. One end of the connecting rod 36 away from the drive motor is fixedly installed with a drive shaft. A push rod 35 is rotatably sleeved on the drive shaft. The other end of the push rod 35 extends downward into the outer cylinder body 31 and is hinged to the top end of the drive piston 33. When the drive motor drives the connecting rod to work, it will drive the connecting rod to rotate. When the connecting rod rotates, it will push and pull the drive piston through the push rod to drive the suction piston to move up and down reciprocally.
[0032] Further, a stirring mechanism 5 is mounted on the capture tank in a matching manner. The stirring mechanism 5 includes a stirring shaft 51 rotatably mounted coaxially in the capture tank. A stirring paddle 52 is mounted on the stirring shaft 51 in a matching manner. The top end of the stirring shaft 51 extends upward out of the capture tank and is connected to a stirring motor 53 in a driving manner. The stirring motor is fixedly mounted on the stirring tank and is connected to the controller. Before discharging the capture liquid after the e-cigarette suction is completed, the controller controls the stirring motor to start and stir the capture liquid in the capture tank. During this process, the flowing capture liquid will continuously wash the surface of the floating ball to separate the aerosol particles adsorbed on the surface from the floating ball. During the stirring process, the floating balls will collide with each other, thereby further improving the capture efficiency of the aerosol.
[0033] When using the electronic cigarette aerosol capture device provided in this embodiment to perform the electronic cigarette aerosol capture operation, after installing the electronic cigarette on the suction seat, start the controller. The controller will first control the liquid supply unit to discharge a fixed amount of capture liquid into the capture tank. As the floating balls in the capture tank will rise continuously following the liquid level of the capture liquid, when the capture liquid submerges the upper filter screen, the upper filter screen will intercept the floating balls and prevent them from continuing to float up with the capture liquid, ensuring that the floating balls always maintain a stable filter medium layer in the middle of the capture liquid. After the capture liquid filling is completed, the controller controls the suction unit to start. The double drive assembly in the suction unit will drive the drive piston to drive the suction piston to reciprocate up and down, imitating the human suction action to suck the electronic cigarette installed on the suction seat, and discharge the aerosol generated by sucking the electronic cigarette into the capture tank through the one-way intake valve and the exhaust pipe group. During this process, the aerosol discharged through the exhaust pipe group will form aerosol bubbles in the capture liquid. Therefore, during the upward floating of the bubbles, the capture solution is used to dissolve and adsorb the particulate matter in the aerosol bubbles. As the bubbles continue to rise, when the aerosol bubbles pass through the filter medium layer, the aerosol bubbles will not only be squeezed by the floating balls, so that the aerosol particles in the aerosol bubbles will be adsorbed on the surface of the floating balls, but also the presence of the floating balls makes the aerosol bubbles be squeezed and deformed or even further burst when passing through the filter medium layer, forming more and smaller bubbles, thereby significantly increasing the contact opportunity between the aerosol particles and the adsorption coating on the surface of the floating balls and improving the capture efficiency. When the number of e-cigarette suction times reaches the preset value, stop suction. The controller controls the stirring mechanism to start, stir the capture liquid, and after stirring, control the drain valve to open to discharge the capture liquid into the storage bottle in the drain chamber. During the stirring process, the flowing capture liquid will continuously wash the surface of the floating balls to separate the aerosol particles adsorbed on the surface from the floating balls, and the floating balls will collide with each other during the stirring process, thereby further improving the capture efficiency of the aerosol. During the drainage process, the lower filter screen will intercept the floating balls to prevent them from being discharged from the capture tank along with the liquid. Embodiment
[0034] The difference between Embodiment 2 and Embodiment 1 is that, asFigure 1 As shown, a control panel is mounted on the side wall of the box on the outdoor side in a matching manner. The control panel is connected to the controller and is used to set the operating parameters of the controller and display the operating status of the controller. Embodiment
[0035] The difference between Embodiment 3 and Embodiment 2 is that, as Figure 8 shown, the drain pipe group includes an annular pipe 421 coaxially installed in the capture tank 4. One side of the annular pipe is provided with a transition pipe 422. One end of the transition pipe is communicated with the annular pipe, and the other end extends out of the capture tank and is installed with a one-way intake valve 39. A plurality of exhaust columns 421 are evenly spaced along the circumferential direction on the upper surface of the annular pipe. An exhaust channel communicating with the inside of the annular pipe is provided vertically in the exhaust column, and a plurality of exhaust holes are evenly spaced vertically on the column body on the clockwise side of the exhaust column. When in use, the gas discharged into the pipe will be discharged from the exhaust holes of each exhaust column. Compared with the existing aerosol capture device where the exhaust pipe is inserted into the solution from top to bottom, when under negative pressure suction, a water film will be formed at the pipe orifice of the exhaust pipe, resulting in the problem that the bubbles are large and not easy to break. When the electronic cigarette aerosol capture device provided in this embodiment is in use, the exhaust holes on the plurality of exhaust columns are evenly distributed, ensuring that the gas can be more evenly distributed in the capture tank. And because the aerosol is supplied and discharged under positive pressure, the possibility of forming a large water film at a single position is reduced, improving the dispersibility and fineness of the bubbles. And the exhaust on the exhaust column is arranged in the clockwise direction, so that during the exhaust process, it has the function of stirring the solution in the capture tank to flow in the clockwise direction, further improving the capture effect. Embodiment
[0036] The difference between Embodiment 4 and Embodiment 3 is that as Figure 2 shown, a docking groove matching the top bottle head of the storage bottle is provided at the bottom of the drain seat. A balloon seat 15 is provided in the discharge chamber in a matching manner. The balloon seat includes a base body 151. A lifting groove is provided vertically on the upper end surface of the base body. A support balloon is installed in the lifting groove in a matching manner. The support balloon cylinder is connected to a supply cylinder. A lifting block 152 is installed in the lifting groove above the support balloon for placing the storage bottle. The supply cylinder is inclined and installed in the discharge chamber, and the piston rod of the supply cylinder is in an extended state in the natural state and extends out of the discharge chamber through the window. When the box door is closed, the inner wall of the box door will push the piston rod of the supply cylinder inward to retract, pushing the internal piston of the supply cylinder to move to inject gas into the support balloon to make it expand, driving the lifting block to drive the storage bottle placed on the lifting block to lift, so that the storage bottle can be automatically lifted and docked with the drain seat when the box door is closed. Embodiment
[0037] The difference between Embodiment 5 and Embodiment 4 is that, as Figure 7As shown in the figure, the storage bottle 6 includes a bottle body 61 and a docking component installed at the top of the bottle body. The docking component includes a guiding cylinder 62, a docking block 63, and an elastic support member. The guiding cylinder 62 is coaxially installed at the top of the bottle body and extends downward into the bottle body for plugging. There is a liquid discharge hole 621 communicating with the inside of the guiding cylinder on the outer ring surface of one side of the guiding cylinder inside the bottle body. The docking block is slidably installed vertically in the guiding cylinder, and the outer ring surface of the docking block blocks the inner hole wall of the liquid discharge hole. The top end of the docking block extends upward out of the guiding cylinder and is provided with a chamfer matching the docking groove at the bottom end of the liquid discharge seat. A docking channel 631 is provided inside the docking block above the liquid inlet hole. The liquid inlet of the docking channel is located at the top of the docking block, and the liquid discharge port of the docking channel overlaps and communicates with the liquid discharge hole of the guiding cylinder. The elastic support member includes a guiding column vertically installed on the bottom surface of the docking block. The guiding column 64 extends downward through the bottom of the guiding cylinder into the bottle body and is connected with a limiting plate 65. A support spring 66 is sleeved on the guiding column inside the guiding cylinder. In the natural state, the support spring will push the docking block upward, separating the docking channel from the liquid discharge hole of the guiding cylinder, and blocking the inner hole wall of the liquid discharge hole through the outer ring surface of the docking block. Thus, when closing the box door, as the storage bottle is lifted, the top end of the docking block will first be inserted into the liquid discharge seat for docking with the liquid discharge seat. As the storage bottle continues to be lifted, the docking block will retract into the guiding cylinder, enabling the internal space of the bottle body to be automatically connected to the liquid discharge seat through the docking channel.
