[0052] Electronic atomizers, such as those used in e-cigarettes, mainly consist of an atomizer and a battery. The atomizer converts liquids, such as e-liquid, into vapor. The main components of e-liquid are mostly propylene glycol, glycerin, nicotine, and flavorings. When powered on, the e-liquid is converted into an aerosol, which is then inhaled into the lungs.

[0053] When testing e-cigarettes with testing equipment, the e-cigarette fluid will gradually accumulate in the suction tube of the testing equipment. Over time, this will cause blockage of the suction tube, affecting the performance of the testing equipment.

[0054] Please see Figure 1 , Figure 2 as well as Figure 3 This application proposes an embodiment of a testing apparatus for testing electronic atomizers to address the above-mentioned problems. The testing device includes a piston-type suction mechanism 10, a three-way tube 20, and a first control valve 30. The piston-type suction mechanism 10 includes a suction tube 11 and a piston pressure mechanism 12 connected to the suction tube 11. The three-way tube 20 has a first port 21, a second port 22, and a third port 23. The first port 21 is connected to the suction tube 11; the second port 22 is used to connect to an electronic atomizer; and the third port 23 is used to connect to an oil container 31. The inlet of the first control valve 30 is connected to the third port 23, and the outlet of the first control valve 30 is connected to the oil container 31. The testing device has a suction mode and an exhaust mode. In the suction mode, the first control valve 30 is closed, and the piston pressure mechanism 12 is used to create a negative pressure in the suction tube 11 to draw the vapor generated by the electronic atomizer into the suction tube 11. In the exhaust mode, the first control valve 30 is open, and the piston pressure mechanism 12 is used to squeeze substances such as vapor and condensate in the suction tube 11 into the oil container 31.

[0055] Please refer to the following: Figure 4The piston-type suction mechanism 10 includes a suction tube 11 and a piston pressure mechanism 12. The suction tube 11 has a hollow chamber. The piston pressure mechanism 12 generates pressure within the suction tube 11, causing a change in the volume of the space within the suction tube 11 used to contain smoke. When the volume of the space within the suction tube 11 used to contain smoke increases, the suction tube 11 can generate negative pressure on the three-way tube 20, allowing smoke generated by the electronic atomizer to be drawn into the suction tube 11 under negative pressure. When the volume of the space within the suction tube 11 used to contain smoke decreases, the smoke within the suction tube 11 can be output to the outside of the suction tube 11 under pressure. In some embodiments, the suction tube 11 has a suction port 111, which connects the hollow chamber of the suction tube 11 and the three-way tube 20. Optionally, the testing device may include a base frame 100, and the piston-type suction mechanism 10 may be mounted on the base frame 100. The piston pressure mechanism 12 includes a stepper motor 121, a coupling 122, a lead screw support 123, a lead screw 124, a drag plate 126, a guide rail 125, and a piston 128. The piston 128 is installed inside the suction tube 11 and can move towards or away from the suction port 111 within the suction tube 11. The space between the piston 128 and the suction port 111 can be used to accommodate smoke. When the piston 128 approaches the suction port 111, it can squeeze the smoke in the suction tube 11 out of the suction port 111. When the piston 128 moves away from the suction port 111, it can create a negative pressure state at the suction port 111, allowing smoke to enter the suction tube 11 from the suction port 111. The stepper motor 121 can be connected to the lead screw 124 via the coupling 122, and the lead screw 124 can be supported by the lead screw support 123. The drag plate 126 can be slidably connected to the base frame 100 via the guide rail 125. The guide rail 125 can be used to limit the movement direction of the drag plate 126. The lead screw 124 is connected to the lead screw nut 129 on the drag plate 126. When the stepper motor 121 is running, the engagement of the lead screw 124 and the lead screw nut 129 can drive the drag plate 126 to move along the guide rail 125. The piston 128 can be connected to the drag plate 126 via the movable joint 127. When the drag plate 126 moves, the movable joint 127 can drive the piston 128 to move synchronously. In some embodiments, multiple sets of suction tubes 11, three-way tubes 20, and first control valves 30 can be provided on each base frame 100. They can be arranged in parallel on the base frame 100 to enable simultaneous testing of multiple electronic atomizers.

[0056] Please see Figure 3 , Figure 4 , Figure 5 as well as Figure 6The three-way tube 20 has three ports: a first port 21, a second port 22, and a third port 23. The first port 21 connects to the suction port 111 of the suction tube 11, the second port 22 connects to the electronic atomizer, and the third port 23 connects to the first control valve 30. The second port 22, the first port 21, and the suction tube 11 form a first passage for drawing in vapor, while the suction tube 11, the first port 21, and the first control valve 30 form a second passage for expelling vapor.

[0057] The first control valve 30 has an inlet and an outlet. The inlet of the first control valve 30 is used to connect to the third port 23 of the three-way pipe 20, and the outlet of the first control valve 30 is used to discharge oil. The first control valve 30 can be opened or closed when needed. In the embodiments of this application, the first control valve 30 can be a check valve, a solenoid valve, or other valve bodies.

[0058] Please see Figure 2 and Figure 6 The oil reservoir 31 is connected to the outlet of the first control valve 30 and is used to store oil. The oil reservoir 31 can be installed inside the base frame, and the inlet of the oil reservoir 31 is connected to the outlet of the first control valve 30 so that the oil output from the first control valve 30 can be collected into the oil reservoir 31.

[0059] The testing device has a suction mode and an exhaust mode. In the suction mode, the first control valve 30 is closed, the second port 22 is connected to the electronic atomizer, and the piston pressure mechanism 12 is used to create a negative pressure in the suction tube 11 so that the smoke generated by the electronic atomizer is drawn into the suction tube 11 from the second port 22, the first port 21 and the suction port 111.

[0060] In exhaust mode, the first control valve 30 is opened, and the piston pressure mechanism 12 applies pressure to the vapor in the suction tube 11, so that the vapor and oil in the suction tube can be sequentially delivered to the first control valve 30 through the suction port 111, the first port 21, and the third port 23 under pressure, and then output by the first control valve 30. In exhaust mode, the second port 22 of the three-way tube 20 can be disconnected from the electronic atomizer, and the vapor and oil can be output to the outside through the suction port 111, the first port 21, and the third port 23.

[0061] In this embodiment, by setting a three-way pipe 20, two passages can be formed at the suction port 111 of the suction pipe through the three-way pipe 20; by setting a first control valve 30, the third port 23 of the three-way pipe 20 can be controlled by the first control valve 30, so that the third port 23 of the three-way pipe 20 can be closed when suction is performed, and in the exhaust mode, the oil in the suction pipe 11 is discharged through the three-way pipe 20 and the first control valve 30 to reduce the accumulation of oil in the suction pipe 11, thereby reducing the problem of blockage of the suction pipe 11 due to oil accumulation.

[0062] In some embodiments, the testing apparatus further includes a smoke detection component 70, which is connected to the suction tube 11 and is used to detect the smoke concentration within the suction tube 11. The smoke detection component 70 may be positioned close to the suction port 111.

[0063] Please see Figure 3 and Figure 7 In some embodiments, an optional structural form of a smoke detection component 70 is disclosed. The smoke detection component 70 includes a transmitter 71, a receiver 72, and a controller 73. The transmitter 71 is disposed on one side of the suction tube 11 and is used to emit a detection beam into the suction tube 11. The receiver 72 is disposed on the other side of the suction tube 11 and is used to receive the detection beam. The controller 73 is connected to the transmitter 71 and the receiver 72 and is used to determine a smoke concentration signal based on the detection beam received by the receiver 72. The transmitter 71 can be used to emit a detection beam, and the receiver 72 can receive the detection beam. When the smoke concentration in the suction tube 11 changes, the detection signal received by the receiver 72 will change synchronously. The controller 73 receives the change signal of the detection beam and determines the smoke concentration based on the change signal. Optionally, in this embodiment, the smoke detection component 70 can be a through-beam fiber optic sensor. In some examples, a fiber optic amplifier 74 can be disposed between the receiver 72 and the controller 73 to amplify the optical signal.

[0064] In some embodiments, the testing apparatus further includes a draw resistance detection component 60, which is connected between the second port 22 and the electronic atomizer. The draw resistance detection component 60 is used to detect the draw resistance of the electronic atomizer. The draw resistance detection component 60 can detect the draw resistance of the electronic atomizer in a vacuum mode. Optionally, the draw resistance detection component 60 can be a differential pressure transmitter.

[0065] Please see Figure 2 and Figure 6In some embodiments, the testing apparatus further includes a negative pressure mechanism 32, which is connected to the outlet of the first control valve 30 and is used to generate negative pressure at the outlet of the first control valve 30 in exhaust mode. The negative pressure mechanism 32 can be a vacuum pump. The negative pressure mechanism 32 can be used to generate negative pressure at the outlet of the first control valve 30 in exhaust mode to accelerate the output of oil from the outlet of the first control valve 30 and reduce blockage of oil at the three-way pipe 20 or the first control valve 30. In some embodiments, the negative pressure mechanism 32 can be installed within the base frame 100. In some embodiments, multiple sets of first control valves 30 can be provided, and multiple sets of first control valves 30 can share a single negative pressure mechanism 32. In some embodiments, the inlet of the negative pressure mechanism 32 is connected to the outlet of the first control valve 30, and the oil reservoir 31 is connected to the outlet of the negative pressure mechanism 32.

In exhaust mode, the fifth port 42 is closed and the sixth port 43 is open. At this time, the vapor and e-liquid in the suction pipe 11 can be output to the outside through the inhalation port 111, the first port 21, the second port 22, the fourth port 41, and the sixth port 43.

Oil can be discharged sequentially through the first port 21, the second port 22, the seventh port 51, and the ninth port 53. In this embodiment, the controllability of the pipeline between the first control valve 30 and the atomizer is improved by providing the second control valve 50. In some embodiments, the testing device further includes a draw resistance detection component 60, which can be disposed between the eighth port 52 and the atomizer. In some embodiments, the testing device includes the receiving component 101 described in any of the above examples. The receiving component 101 is at least partially disposed below the ninth port 53 so that it can be used to receive oil output from the ninth port 53.

[0074] The above are merely embodiments of this application and do not limit the scope of this patent application. Any equivalent structural or procedural changes made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection of this application.
