Description

Technical Field

[0001] This application relates to the field of automated testing technology, and in particular to a testing device, testing system, and testing method for atomizers. Background Technology

[0002] Common aerosol generating devices consist of an atomizer and a power supply, with the atomizer connected to the power supply. During operation, the power supply provides power to the atomizer.

[0003] The atomizer includes a mouthpiece, an atomizing component, and a liquid reservoir. The liquid reservoir stores the aerosol-generating matrix, and the atomizing component heats the aerosol-generating matrix to form an aerosol. The mouthpiece is connected to the atomizing component, and the aerosol formed can be expelled through the mouthpiece during inhalation.

[0004] The draw resistance of an atomizer and the heating temperature of the atomizing components have a significant impact on atomization performance. For example, both draw resistance and heating temperature affect the aerosol concentration. To achieve better atomization, the draw resistance and heating temperature of an atomizer typically need to be measured. However, the measurement efficiency in related technologies is usually low, and there is also a risk of damaging the atomizer. Summary of the Invention

The orientation of the infrared temperature probe is opposite to the insertion direction of the nozzle socket. The infrared temperature probe is directly opposite to the end of the nozzle socket and is used to detect the airway temperature inside the atomizer inserted into the nozzle socket. A pressure sensor is used to detect the air pressure in the air extraction channel.

One end of the first through hole is disposed directly opposite the end. The infrared temperature probe is located on the side of the substrate away from the mounting block and is disposed directly opposite the first through hole.

[0008] In some examples, the first through hole is a threaded hole, and a portion of the infrared temperature probe is inserted into the first through hole and threadedly connected to it.

[0009] In some examples, the air extraction channel is disposed in the substrate, with one end opening on the wall of the first through hole and the other end opening on the outer surface of the substrate.

[0010] In some examples, the mounting block includes a flexible portion and a rigid portion, the flexible portion being integrally formed with the rigid portion, and the nozzle insertion port being disposed in the flexible portion.

[0011] In some examples, the rigid portion is disposed around the flexible portion, and the rigid portion is detachably connected to the substrate.

[0012] In some examples, the detection device further includes a support and a bracket, the base and the bracket being connected to the support respectively, the bracket being located on the side of the insertion end away from the end, the bracket being used to support the atomizer.

[0013] In some examples, the bracket is movably connected to the support, and the bracket is movable relative to the support in the height direction.

[0014] In some examples, the bracket includes a tray and a lifting rod that connects the tray and the support.

[0015] Secondly, embodiments of this application also provide a detection system for an atomizer, the detection system including an air extraction device, a controller and at least one detection device as described in the first aspect, the air extraction device being connected to the air extraction channel, and the infrared temperature probe, the air pressure sensor and the air extraction device being electrically connected to the controller respectively.

[0016] Thirdly, embodiments of this application also provide a method for detecting an atomizer, the detection method being based on the detection system described in the second aspect, the detection method comprising: Insert the atomizer nozzle into the nozzle socket; Air is drawn out using the aforementioned air extraction device at a preset flow rate; The air pressure in the air extraction channel is obtained through the air pressure sensor; The temperature of the air passage inside the atomizer is obtained through the infrared temperature probe.

[0017] The beneficial effects of the technical solutions provided in this application include at least the following: By providing a mouthpiece inlet on one side of the base, along with an air extraction channel connected to the mouthpiece inlet, the atomizer's mouthpiece can be inserted into the mouthpiece inlet for testing. Air is then drawn out through the air extraction channel at a preset flow rate. A pressure sensor detects the air pressure within the air extraction channel, thus determining the atomizer's draw resistance. An infrared temperature probe is mounted on the base. Since the probe's orientation is opposite to the mouthpiece inlet's insertion direction (facing the end of the mouthpiece inlet), it can obtain the temperature of the atomizer's internal airflow without penetrating the atomizer. This avoids obstructing the airflow and preventing damage from collisions with the airflow channel. This device simultaneously detects draw resistance and airflow temperature, improving testing efficiency and minimizing the risk of damage by avoiding collisions with the atomizer's internal airflow.

[0027] Figure 1 This is a schematic diagram of the structure of a liquid heating device provided in an embodiment of this application, as shown below. Figure 1 As shown, the liquid heating device includes a power supply assembly 100 and an atomizer 200. The power supply assembly 100 is used to supply power to the atomizer 200.

[0028] Figure 2 This is a schematic diagram of the internal structure of an atomizer provided in an embodiment of this application, as shown below. Figure 2 As shown, the atomizer 200 includes a liquid storage assembly 210, a heating assembly 220, and a nozzle 230. The liquid storage assembly 210 stores the aerosol generation matrix. The heating assembly 220 is located in the liquid storage assembly 210 and is used to heat the aerosol generation matrix. The heating assembly 220 forms an atomization channel 220a. The nozzle 230 is connected to one end of the atomization channel 220a.

[0029] The liquid storage assembly 210 may include a liquid reservoir housing 211, the interior of which forms a liquid reservoir 200a for containing the aerosol generation matrix. The liquid storage assembly 210 may also include a sealing base 212, which may be fixedly connected to or detachably connected to the liquid reservoir housing 211. The sealing base 212 may be used to mount electrodes 2121 for electrical connection to the power supply assembly 100. The sealing base 212 may also be provided with an air inlet 212a, which communicates with the atomization channel 220a.

[0030] In some examples, the liquid storage assembly 210 may also include a liquid storage element, such as a liquid storage cotton that has been adsorbed / wetted with an aerosol generation matrix.

[0031] The heating assembly 220 is located in the liquid tank housing 211. The heating assembly 220 includes an atomizing core cover 221 and an atomizing core 201, with the atomizing core 201 inserted into the atomizing core cover 221.

[0032] The atomizing core 201 may include a liquid guiding element 222, a heating element 223, and a pin 224. The liquid guiding element 222 and the heating element 223 are located within the atomizing core casing 221. The pin 224 is electrically connected to the heating element 223. The pin 224 also extends outside the atomizing core casing 221 and is connected to an electrode 2121.

[0033] The atomizing core cover 221 provides space inside the liquid tank housing 211 to accommodate the liquid guiding component 222 and the heating component 223. The atomizing core cover 221 may be cylindrical, and its wall may have structures such as holes and slits to allow the aerosol generating matrix in the liquid tank housing 211 to enter the atomizing core cover 221 and be absorbed by the liquid guiding component 222. The heating component 223 is used to heat the aerosol generating matrix in the liquid guiding component 222, causing the aerosol generating matrix to vaporize.

[0034] The material and structure of the heating element 223 are not limited, as long as it can generate heat. For example, the heating element 223 may include at least one of heating mesh, heating film, heating wire, and heating plate.

[0035] The atomizer core cover 221 can be made of PCTG (Polycyclohexylenedimethylene Terephthalate Glycol), PEEK (Polyether Ether Ketone), or metal. PCTG, short for polyethylene terephthalate-1,4-cyclohexanediethanol ester, is a non-crystalline copolyester formed by the cocondensation of terephthalic acid (PTA), ethylene glycol (EG), and 1,4-cyclohexanediethanol (CHDM). PCTG is also known as a copolyester or modified polyester. PEEK, short for polyether ether ketone, is a thermoplastic special engineering plastic.

[0036] During the use of the aerosol generating device, the user inhales through the mouthpiece 230. Air enters the atomization channel 220a through the air inlet 212a, then enters the mouthpiece 230 through the atomization channel 220a, and finally exits from the mouthpiece 230. The air carries away the aerosol formed in the atomization channel 220a as it passes through it. When the user inhales, a negative pressure is created at the mouthpiece 230; the magnitude of this negative pressure is the suction resistance of the atomizer 200. The suction resistance of the atomizer 200 and the temperature of the air passage within the atomizer 200 have a significant impact on the atomization effect of the atomizer 200. The air passage of the atomizer 200 can include the channel through which air flows from the air inlet 212a to the outlet of the mouthpiece 230, for example, including the atomization channel 220a.

[0037] Excessive draw resistance obstructs airflow from the nozzle 230, resulting in insufficient mist output; insufficient draw resistance leads to a lower concentration of expelled aerosol; excessively high temperature within the atomization channel 220a may cause a burnt taste in the aerosol; excessively low temperature within the atomization channel 220a will result in insufficient atomization and low mist output. To ensure that the draw resistance of the atomizer 200 and the temperature within the airway are at suitable levels during operation, it is usually necessary to separately detect the draw resistance and the temperature within the airway. In related technologies, draw resistance and temperature detection are typically performed separately, which is relatively inefficient. When detecting the temperature within the airway, a temperature sensor needs to be inserted from the nozzle 230 into the airway. During the detection process, the temperature sensor may come into contact with the atomizing core 201, such as with the heating element 223, potentially causing damage to the atomizing core 201.

[0038] In order to improve the detection efficiency of the atomizer 200 and reduce the risk of damage to the atomizer 200 during the detection process, this application provides a detection device and detection system for the atomizer.

[0039] Figure 3 This is a schematic diagram of the structure of a detection device for an atomizer provided in an embodiment of this application, as shown below. Figure 3 As shown, the detection device includes a base 30, an infrared temperature probe 40, and a pressure sensor.

[0040] The base 30 has a mouthpiece socket 32a on one side. The mouthpiece socket 32a includes an insert end and an end end. The insert end is located on the outer surface of the base 30, and the end end is located inside the base 30. When testing the atomizer 200, the mouthpiece 230 of the atomizer 200 can be inserted into the mouthpiece socket 32a from the insert end.

[0041] The base 30 also includes an air extraction channel 31a, one end of which connects to the end of the nozzle inlet 32a, and the other end of which extends to the outer surface of the base 30. A pressure sensor is used to detect the air pressure within the air extraction channel 31a.

[0042] An infrared temperature probe 40 is mounted on the base 30. The orientation of the detection port 40a of the infrared temperature probe 40 is opposite to the insertion direction of the nozzle socket 32a. The infrared temperature probe 40 is directly opposite to the end of the nozzle socket 32a. The infrared temperature probe 40 is used to detect the airway temperature inside the atomizer 200 inserted in the nozzle socket 32a.

[0043] During testing, the nozzle 230 of the atomizer 200 is inserted into the nozzle socket 32a from the insertion end. The insertion direction of the nozzle socket 32a refers to the direction from the insertion end to the end of the nozzle socket 32a. The infrared temperature probe 40 is oriented opposite to the insertion direction of the nozzle socket 32a, and the infrared temperature probe 40 is directly facing the end of the nozzle socket 32a, so that after the nozzle 230 of the atomizer 200 is inserted into the nozzle socket 32a, the infrared temperature probe 40 faces the inside of the air passage of the atomizer 200.

[0044] Airway temperature refers to the temperature of the inner wall of the airway of the atomizer 200. The airway may include the atomization channel 220a or a section of the atomization channel 220a. For example, the airway may include the section of the atomization channel 220a where the heating element 223 is located.

[0045] By providing a mouthpiece inlet 32a on one side of the base 30, and also providing an air extraction channel 31a on the base 30, with one end of the air extraction channel 31a connected to the end of the mouthpiece inlet 32a, when testing the atomizer 200, the mouthpiece 230 of the atomizer 200 can be inserted from the insertion end of the mouthpiece inlet 32a, and air can be drawn outward through the air extraction channel 31a at a preset flow rate. The air pressure in the air extraction channel 31a is detected by the air pressure sensor to obtain the suction resistance of the atomizer 200. By installing an infrared temperature probe 40 on the base 30, and since the orientation of the infrared temperature probe 40 is opposite to the insertion direction of the mouthpiece socket 32a, with the probe directly facing the end of the mouthpiece socket 32a, the infrared temperature probe 40 can obtain the airflow temperature inside the atomizer 200 without extending into it. Therefore, it will not block the airflow of the atomizer 200, affecting the extraction through the suction channel 31a, nor will it collide with the airflow and damage the atomizer 200. This detection device can simultaneously detect suction resistance and airflow temperature, improving detection efficiency and avoiding collisions with the airflow inside the atomizer 200, greatly reducing the risk of damage to the atomizer 200.

[0046] Figure 4 This is a schematic diagram of the structure of a base provided in an embodiment of this application, such as... Figure 4 As shown, in this example, the detection device 300 may further include a suction pipe 311, one end of which is connected to the end of the suction channel 31a away from the nozzle inlet 32a. The suction pipe 311 can be used to connect a suction device, such as a suction pump.

[0047] In some examples, the pressure sensor can be directly placed in the suction channel 31a, creating a negative pressure within it during suction. The difference between the absolute pressure within the suction channel 31a and atmospheric pressure is the suction resistance. The closer the pressure sensor is to the nozzle inlet 32a in the suction channel 31a, the more accurate the suction resistance reading.

[0048] In some other possible implementations, the pressure sensor can also be placed in the suction pipe to facilitate its installation.

[0049] For example, the positive and negative pressure detection range of the pressure sensor can be 0~5000Pa, and the accuracy can be ±1%. The pressure sensor can detect relative pressure, that is, the relative magnitude of the pressure in the suction channel 31a and atmospheric pressure. Atmospheric pressure can refer to standard atmospheric pressure.

[0050] Figure 5 This is an exploded structural diagram of a detection device for an atomizer provided in an embodiment of this application, as shown below. Figure 5 As shown, the base 30 may include a base 31 and a mounting block 32. A mounting groove 31b is provided on one side of the base 31, and the mounting block 32 is detachably disposed in the mounting groove 31b. A suction nozzle inlet 32a is disposed on the mounting block 32.

[0051] The base 31 provides support, and the mouthpiece inlet 32a is mounted on the mounting block 32. The mounting block 32 is detachably connected to the base 31, allowing for easy replacement of different mounting blocks 32. Different mounting blocks 32 can have mouthpiece inlets 32a of different sizes and / or shapes to accommodate different atomizers 200, facilitating testing of different models of atomizers 200.

[0052] As an example, the mounting groove 31b can extend through the height direction Z to the top surface of the base 31, so that when the mounting block 32 is removed, the mounting block 32 can be slid upward out of the mounting groove 31b.

[0053] like Figure 5 As shown, the nozzle insertion port 32a is disposed through the mounting block 32 along the first direction X. As an example, the first direction X can be the thickness direction of the base 31, and the first direction X is perpendicular to the height direction Z. The first direction X can be parallel to the insertion direction of the nozzle insertion port 32a.

[0054] The substrate 31 has a first through hole 31c that runs through the substrate 31 along the first direction X. One end of the first through hole 31c is positioned opposite the end of the nozzle insertion port 32a. The infrared temperature probe 40 is located on the side of the substrate 31 away from the mounting block 32, and the infrared temperature probe 40 is positioned opposite the first through hole 31c.

[0055] The infrared temperature probe 40 and the mounting block 32 are respectively arranged on opposite sides of the base 31, at both ends of the first through hole 31c, resulting in a simple structure. The first through hole 31c penetrates the base 31 along the first direction X, ensuring that when arranging the infrared temperature probe 40 and the mounting block 32, both ends of the first through hole 31c and both ends of the nozzle inlet 32a are on the same straight line. Infrared radiation generated in the airway during atomizer 200 operation can be directed to the infrared temperature probe 40 through the first through hole 31c, which helps improve the accuracy of the infrared temperature probe 40's detection.

[0056] The infrared temperature probe 40 can be mounted on the base 31 and sealed with the first through hole 31c to prevent air leakage at the end of the first through hole 31c near the infrared temperature probe 40.

[0057] The infrared temperature probe 40 can be an infrared temperature probe 40 with high optical resolution. For example, the distance coefficient of the infrared temperature probe 40 can be 30:1, that is, the ratio of the distance from the infrared temperature probe 40 to the target to the diameter of the target is 30:1.

[0058] The infrared temperature probe 40 has a temperature detection range of 0~200℃ and an accuracy of ±1%.

[0059] For example, the first through hole 31c can be a threaded hole, and part of the infrared temperature probe 40 is inserted into the first through hole 31c, and the infrared temperature probe 40 is threadedly connected to the first through hole 31c.

[0060] By rotating the infrared temperature probe 40, the distance between the infrared temperature probe 40 and the end of the suction nozzle 32a can be adjusted to improve the accuracy of the detection.

[0061] like Figure 5 As shown, the air extraction channel 31a is disposed in the substrate 31. One end of the air extraction channel 31a is opened on the wall of the first through hole 31c, and the other end of the air extraction channel 31a is opened on the outer surface of the substrate 31.

[0062] The suction channel 31a is connected to the wall of the first through hole 31c, and the first through hole 31c connects the suction channel 31a to the nozzle inlet 32a without affecting the infrared temperature probe 40's temperature detection of the atomizer 200's airway. When changing to different atomizers 200 for testing, the nozzle 230 will not obstruct the suction channel 31a, and the suction process will not be affected.

[0063] Figure 6 This is a schematic diagram of the structure of an installation block provided in an embodiment of this application, such as... Figure 6As shown, the mounting block 32 may include a flexible portion 321 and a rigid portion 322, wherein the elasticity of the flexible portion 321 is greater than that of the rigid portion 322. The suction nozzle inlet 32a is provided in the flexible portion 321.

[0064] The nozzle insertion port 32a is located in the flexible part 321. The flexible part 321 has a certain elasticity. When the nozzle 230 of the atomizer 200 is inserted into the nozzle insertion port 32a, compression can be formed between the flexible part 321 and the outer surface of the nozzle 230, so that a good seal is formed between the flexible part 321 and the nozzle 230, avoiding air leakage from the nozzle insertion port 32a and affecting the detection of suction resistance.

[0065] For example, the flexible part 321 may be formed of rubber or silicone material; the rigid part 322 may be formed of plastic, metal or non-metal material.

[0066] In some examples, the flexible part 321 and the rigid part 322 are integrally formed, that is, the mounting block 32 can be a one-piece structure. For example, the mounting block 32 can be formed using a two-color injection molding process or an insert molding process.

[0067] The integral molding of the flexible part 321 and the rigid part 322 not only ensures a tight connection between the flexible part 321 and the rigid part 322, but also prevents air leakage at the connection between the flexible part 321 and the rigid part 322.

[0068] like Figure 6 As shown, the rigid part 322 can be arranged around the flexible part 321, and the rigid part 322 is detachably connected to the base 31.

[0069] The rigid part 322 may be plate-shaped, and an opening may be provided in the center of the rigid part 322. The flexible part 321 may be disposed in the opening in the center of the rigid part 322. The rigid part 322 is disposed around the flexible part 321, which can provide better support for the flexible part 321, so that the flexible part 321 can be stably connected to the nozzle 230 of the atomizer 200.

[0070] For example, the rigid part 322 may be provided with a plurality of connecting holes 322a, which may be arranged around the flexible part 321. The rigid part 322 can be connected to the base 31 by screws, which can ensure that the mounting block 32 is firmly installed and facilitate the disassembly of the mounting block 32.

[0071] like Figure 3 As shown, the detection device 300 may further include a bracket 50 and a support 60, with the base 30 and support 60 respectively connected to the bracket 50. The support 60 is located on the side of the insertion end of the nozzle port 32a away from the end, and the support 60 is used to support the atomizer 200.

[0072] The bracket 50 facilitates the installation of the entire testing device 300. When testing the nebulizer 200, the nozzle 230 of the nebulizer 200 is inserted into the nozzle socket 32a. The bracket 60 supports the liquid storage component 210, keeping the nebulizer 200 stable and preventing the nebulizer 200 from coming out of the nozzle socket 32a.

[0073] In some examples, bracket 60 can be movably connected to support 50, and bracket 60 can move relative to support 50 in the height direction Z, that is, the height of bracket 60 is adjustable.

[0074] Different atomizers 200 have different shapes and / or sizes, and the height of the reservoir component 210 after the mouthpiece 230 is inserted into the mouthpiece socket 32a often varies. By setting a height-adjustable bracket 60, the height of the bracket 60 can be adjusted according to the atomizer 200 being tested, so that the bracket 60 can stably support the atomizer 200 and prevent the reservoir component 210 from being too high or too low, which would cause the atomizer 200 to tilt and affect the airtightness between the mouthpiece 230 and the mouthpiece socket 32a.

[0075] As an example, bracket 60 may include a tray 61 and a lifting rod 62. The lifting rod 62 connects the tray 61 and the bracket 50.

[0076] The lifting rod 62 can move along the height direction Z, driving the pallet 61 to rise and fall. The lifting rod 62 can extend or retract along the height direction Z, or move along the height direction Z.

[0077] The travel distance of the pallet 61 can be 35mm, that is, the height difference between the highest and lowest positions of the pallet 61 is 35mm.

[0078] In some examples, the lifting rod 62 may include a telescopic rod, one end of which is fixedly connected to the bracket 50, and the other end of which is connected to the pallet 61. By extending and retracting the lifting rod 62, the pallet 61 is moved in the height direction Z, thereby changing the height position of the pallet 61.

[0079] For example, the lifting pole 62 may include an electrically operated telescopic pole.

[0080] As an example, such as Figure 3 As shown, the lifting rod 62 may include a screw, one end of which is connected to the support plate 61, and the other end of which passes through the bracket 50. The screw and the bracket 50 are threaded together. The screw can be moved relative to the bracket 50 along its own axis, thereby driving the support plate 61 to move in the height direction Z, changing the height position of the support plate 61.

[0081] The screw can be rotatably connected to the support plate 61, so that the support plate 61 does not rotate with the screw during the process of turning the screw to adjust the height of the support plate 61.

[0082] For example, a bearing may be provided on the side of the support plate 61 near the bracket 50, with the outer ring of the bearing connected to the support plate 61 and the inner ring of the bearing fitted onto the screw. A groove may be provided on the support plate 61, and the bearing may be placed in the groove, with the outer ring of the bearing interference fit with the groove and the inner ring of the bearing interference fit with the screw.

[0083] like Figure 3 As shown, the end of the lifting rod 62 away from the tray 61 can also be connected to a screw handle 621, so that the testing personnel can manually screw the lifting rod 62 to adjust the height of the tray 61.

[0084] A guide rod 611 can also be connected to the side of the pallet 61 near the bracket 50. The bracket 50 is provided with a guide hole 50a. One end of the guide rod 611 is connected to the pallet 61, and the other end of the guide rod 611 is inserted into the guide hole 50a with a clearance fit. During the process of the lifting rod 62 driving the pallet 61 to rise or fall, the guide rod 611 cooperates with the guide hole 50a to make the movement of the pallet 61 more stable.

[0085] As an example, two guide rods 611 can be provided, and the lifting rod 62 can be provided between the two guide rods 611. By using two guide rods 611 to cooperate with the bracket 50 respectively, the lifting and lowering of the pallet 61 can be made more stable.

[0086] Figure 7 This is a schematic diagram of the structure of a detection system for an atomizer provided in an embodiment of this application, as shown below. Figure 7 As shown, the detection system includes an air extraction device, a controller, and at least one detection device 300 as previously shown. The air extraction device is connected to the air extraction channel 31a, and the infrared temperature probe 40, the air pressure sensor, and the air extraction device are electrically connected to the controller.

[0087] The controller can be used to control the operation of the air extraction device, the infrared temperature probe 40, and the air pressure sensor.

[0088] For example, the controller may include at least one of a computer, a microcontroller unit (MCU), a central processing unit (CPU), a field programmable gate array (FPGA), or other programmable logic devices.

[0089] The controller's control of the suction device, infrared temperature probe 40, and pressure sensor can be based on a pre-set computer program. The detection system may also include a computer-readable storage medium for storing this computer program. This computer-readable storage medium may include: computer memory, read-only memory (ROM), etc. Only memory (ROM), random access memory (RAM), electrical carrier signals, telecommunication signals, and software distribution media.

[0090] The detection system may include a machine casing 400, and the air extraction device and controller may be located inside the machine casing 400.

[0091] As an example, the detection system may also include a display panel 401, which may be disposed on the outer surface of the casing 400. The display panel 401 may be used to display data during the detection process, such as the working status of the suction device, the working status of the infrared temperature probe 40, the working status of the pressure sensor, the flow rate of the suction device, the detection results of the infrared temperature probe 40, the detection results of the pressure sensor, the suction resistance of the nozzle 230, etc., to facilitate operation by the detection personnel.

[0092] Display panel 401 may be a touch display panel with touch function to further facilitate operation by inspection personnel.

[0093] A detection area 402 may be provided on one side of the outer casing 400, and a detection device 300 may be disposed in the detection area 402. In some examples, the detection system may include multiple detection devices 300, which may be arranged side by side in the detection area 402. For example, the multiple detection devices 300 may be arranged along a second direction Y, which may be perpendicular to the height direction Z and perpendicular to the first direction X.

[0094] Figure 8 This is a flowchart illustrating a method for detecting an atomizer according to an embodiment of this application. The method involves detecting the atomizer 200 based on the aforementioned inspection system. Figure 8 As shown, the detection method includes: In step S10, the nozzle 230 of the atomizer 200 is inserted into the nozzle socket 32a.

[0095] In step S12, air is drawn out using an air extraction device at a preset flow rate.

[0096] During the air extraction process, the heating element 220 of the atomizer 200 is in a heated state.

[0097] In step S14, the air pressure in the air extraction channel 31a is obtained by the air pressure sensor.

[0098] In step S14, the absolute air pressure inside the suction channel 31a can be obtained, and the suction resistance can be obtained based on the difference between the absolute air pressure and atmospheric pressure. Alternatively, in step S14, the relative air pressure inside the suction channel 31a can be obtained, that is, the air pressure with atmospheric pressure as a reference, and the magnitude of this air pressure is the suction resistance.

[0099] In step S16, the airway temperature inside the atomizer 200 is obtained by infrared temperature probe 40.

[0100] In the above method, the air extraction process of the air extraction device can continue until the detection of the atomizer 200 is completed, that is, step S12 can continue until steps S14 and S16 are completed. Since the infrared temperature probe 40 does not obstruct the airflow in the air passage of the atomizer 200, steps S14 and S16 can be performed simultaneously or sequentially.

[0101] After the test is completed, the performance of atomizer 200 can be determined based on the test results. If the draw resistance and temperature are both within acceptable limits, then atomizer 200 is acceptable; if either the draw resistance or the temperature is unacceptable, then atomizer 200 is unacceptable.

[0102] The above method can be executed by the aforementioned controller. The controller can be divided into different modules according to the functions it performs, such as a suction resistance calculation module, a temperature calculation module, and an output module. The suction resistance calculation module can be electrically connected to a pressure sensor to obtain the suction resistance based on the signal output by the pressure sensor. The temperature calculation module can be electrically connected to an infrared temperature probe 40 to obtain the airway temperature based on the signal output by the infrared temperature probe 40. The output module can be electrically connected to a display panel 401 to output the detected suction resistance and temperature to the display panel 401 for display. For example, the temperature calculation module can use a difference analysis algorithm to calculate the airway temperature.

[0103] The controller provided in the above embodiment is only an example of the division of the above functional modules when controlling the detection system to detect the atomizer 200. In actual applications, the above functions can be assigned to different functional modules as needed, that is, the internal structure of the device can be divided into different functional modules to complete all or part of the functions described above.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
