Compared with aerosol-generating base materials having a columnar or other shape, the thickness of the aerosol-generating base tape 30 is very thin, so that the temperature rises uniformly during heating, the temperature rise rate is fast, and the overflow path of the aerosol generated by the aerosol-generating base tape 30 being heated and atomized is short, so that preheating is not necessary. Note that the specific sizes of the thickness and width of the aerosol-generating base tape 30 are not limited and may be set as necessary to meet different requirements.

[0030] Furthermore, the aerosol-generating base tape 30 is made by mixing one or more of tobacco leaves, expanded tobacco stems, tobacco granules, tea leaves, and mint leaves, one or more of propylene glycol, glycerin, or other polyhydric alcohols as smoke generating agents, and materials such as flavorings to form a slurry, so that it can generate an aerosol to be inhaled by a person by heating and atomizing it.

[0035] In another embodiment, the electronic atomization device further includes a collection chamber 30, and the drive module 13 is located on one side of the collection chamber 30 and includes a supply motor, a discharge wheel 135, a supply drive wheel group 136 and a roller shaft group 137, the supply drive wheel group 136 includes two supply drive wheels spaced apart from each other, and a gap is formed between the outer circumferential surfaces of the two supply drive wheels through which the aerosol-generating base tape 30 passes, and the roller shaft group 137 includes two roller shafts spaced apart from each other, and a gap is formed between the outer circumferential surfaces of the two roller shafts through which the aerosol-generating base tape 30 passes.

[0036] The supply drive wheel group 136 and the roller shaft group 137 are spaced apart in the transport direction of the aerosol-generating base tape 30, the discharge wheel 135 is located on the side of the supply drive wheel group 136 remote from the roller shaft group 137, and the atomization module 14 is located between the supply drive wheel group 136 and the roller shaft group 137. The supply motor is operably connected to the supply drive wheel group 136, and the supply drive wheel group 136 is driven to rotate by the supply motor to constantly advance the aerosol-generating base tape 30 and atomize it, and the aerosol-generating base tape 30 heated and atomized by the atomization module 14 enters the collection chamber 30 and is collected.

[0037] In another embodiment, the supply motor may be operably connected to the supply drive wheel group 136 and the roller shaft group 137, respectively, and the supply drive wheel group 136 and the roller shaft group 137 are rotated by the drive of the supply motor, thereby driving the aerosol-generating base tape 30 to constantly advance and atomize it, and the aerosol-generating base tape 30 heated and atomized by the atomization module 14 enters the collection chamber 30 and is collected.

[0038] In some embodiments, the electronic atomization device further includes a supply detection module 16. The supply detection module 16 is disposed in the moving path of the aerosol-generating base tape 30, preferably disposed upstream of the atomization module 14. The supply detection module 16 is communicatively connected to the main control module 11 and electrically connected to the power supply module, and is controlled by the main control module 11 to detect the real-time release length of the aerosol-generating base tape 30 and feed it back to the main control module 11, thereby accurately controlling the release length of the aerosol-generating base tape 30, timely supplying the aerosol-generating base tape 30 to the atomization module 14, and preventing waste of the aerosol-generating base tape 30.

[0039] Specifically, in one embodiment, the supply detection module 16 includes two rotating members 162, a sensing unit, and a detection unit. The two rotating members 162 are spaced apart from each other, and a gap is formed between the outer circumferential surfaces of the two rotating members 162 to allow the aerosol-generating base tape 30 to pass through. The two rotating members 162 are attached to both sides of the aerosol-generating base tape 30 in the thickness direction, respectively, and rotate in conjunction with the aerosol-generating base tape 30. At least one of the rotating members 162 is provided with a sensing unit, which may specifically be a magnetic sensing member, a photoelectric sensing member, or a mechanical sensing member. The detection unit is provided on one side of the rotating member 162 and is a Hall sensor, a light shielding plate, a mechanical sensing element, or the like, that matches the sensing unit.

[0040] In this way, the detection unit can obtain the rotation angle or number of rotations of the rotating member 162 by calculating the number of times the sensing unit passes, and can further obtain the real-time release length of the aerosol-generating substrate tape 30 based on the rotation angle or number of rotations of the rotating member 162. Note that the type of the sensing unit in the rotating member 162 is not limited and may be other features or elements detectable by the detection unit. Accordingly, the type of the detection unit is set according to the type of the sensing unit so as to match the sensing unit.

[0041] In another embodiment, the supply motor has a motor encoder, and the drive shaft of the supply motor is in direct contact with the aerosol-generating base tape 30 to drive and move the aerosol-generating base tape 30, and the supply detection module 16 is connected to the motor encoder of the supply motor, and can obtain the real-time release length of the aerosol-generating base tape 30 by obtaining the number of rotations of the motor encoder.

[0043] The start / stop signal input module 12 is provided in the main housing and may be a mechanical key, a touch key, a fingerprint key, a hall sensor, or an airflow sensor capable of sensing airflow. The method of acquiring a start command or a stop command is not limited, and the start / stop signal input module 12 may acquire a corresponding start signal or stop signal by voice recognition or gesture recognition.

[0044] In some embodiments, the electronic atomization device further includes a status indication module 17, which is communicatively connected to the main control module 11 and electrically connected to the power supply module, and indicates the operation status of the electronic atomization device under the control of the main control module 11. Specifically, the status indication module 17, under the control of the main control module 11, can issue signals such as images, characters, light, vibration, and sound to indicate the heating status, transmission status, and inhalation signal of the electronic atomization device to the user, so as to clearly inform the user of the operation status of the electronic atomization device.

[0045] In some embodiments, the electronic atomization device further includes an attachment detection module 18, which is communicatively connected to the main control module 11 and detects whether a substrate cartridge is present in the electronic atomization device. If the attachment detection module 18 detects that a substrate cartridge is not present in the electronic atomization device, it can feed back the detection result to the main control module 11, and the main control module 11 can prohibit the activation of the atomization module 14 based on the detection result. If the attachment detection module 18 detects that a substrate cartridge is present in the electronic atomization device, it can feed back the detection result to the main control module 11, and the main control module 11 can allow the activation of the atomization module 14 based on the detection result.

[0046] Specifically, the substrate cartridge is provided with a sensing element, such as a Hall sensor or a photoelectric sensor, that matches the mounting detection module 18. The mounting detection module 18 may be a magnetic element that matches the Hall sensor or a light shield that matches the photoelectric sensor. The Hall sensor can determine whether the substrate cartridge is present in the electronic atomization device by detecting whether the magnetic element is present, and the photoelectric sensor can determine whether the substrate cartridge is present in the electronic atomization device by detecting whether the light shield is present.

[0047] In some embodiments, the electronic atomization device further includes a remaining amount detection module 19, which is communicatively connected to the main control module 11 and detects the remaining amount of the unreleased portion of the aerosol-generating substrate tape 30, thereby prompting the user to timely inspect and replace the substrate cartridge or the aerosol-generating substrate tape 30. Specifically, the remaining amount detection module 19 detects the change in the lock current of the supply motor of the driving module 13, the change in the temperature curve of the atomization module 14, or the volume of the aerosol-generating substrate tape 30, obtains the remaining amount of the aerosol-generating substrate tape 30, and feeds it back to the main control module 11, and further outputs a signal including, but not limited to, an image, a character, a light, a vibration, and a sound to prompt the user to inspect and replace the aerosol-generating substrate tape 30.

[0048] As shown in FIGS. 4 and 5, the atomization control method for the electronic atomization device includes the following steps S1 to S2.

[0049] In step S1, an activation signal is obtained and the electronic atomizer is controlled to enter an atomization period according to the activation signal.

[0050] Specifically, the device that obtains the start signal is the start / stop signal input module 12, and when the user presses the start / stop signal input module 12, the start / stop signal input module 12 can obtain the start signal and transmit it to the main control module 11. Note that the manner in which the start / stop signal input module 12 obtains the start command is not limited, and the start / stop signal input module 12 may obtain the start signal by fingerprint recognition, touch recognition, airflow sensing, voice recognition, gesture recognition, etc.

[0051] Step S1 of acquiring the start signal and controlling the electronic atomization device to enter an atomization cycle in response to the start signal specifically includes the following steps S11 to S14.

[0052] In step S11, an inhalation signal is acquired, and the aerosol-generating base tape 30 is heated and atomized in response to the inhalation signal.

[0053] Specifically, an airflow sensor is provided in the electronic atomization device, and when a user uses the airflow sensor, the airflow sensor can be triggered to send an inhalation signal to the main control module 11. In response to the inhalation signal, the main control module 11 controls the atomization module 14 to heat and atomize the aerosol-generating substrate tape 30 to generate an aerosol, which is inhaled by the user.

[0054] Specifically, in one embodiment, the atomization module 14 heats and atomizes the aerosol-generating substrate tape 30 in a high-power, fast-start manner. After each inhalation signal is obtained, the heating time of the atomization module 14 is 2.0 seconds to 3.0 seconds, preferably 2.0 seconds to 2.5 seconds, and within a time of 0.2 seconds to 1 second from the start, the atomization module 14 quickly heats up to the maximum heating temperature, which can reach 350°C to 700°C.

[0055] In this way, when a user uses the electronic atomization device, the atomization module 14, under the control of the main control module 11, instantly heats the aerosol-generating substrate tape 30 to rapidly generate aerosol for inhalation by the user, without the need to wait for pre-heating, thereby improving the user experience of the electronic atomization device.

[0056] In step S12, the real-time number of inhalations is obtained, and when it is determined that the real-time number of inhalations reaches a preset number of inhalations, the aerosol-generating base tape 30 is released for renewal.

[0057] Specifically, the main control module 11 acquires the real-time number of inhalations and compares the real-time number of inhalations with the preset number of inhalations. When the main control module 11 determines that the real-time number of inhalations reaches the preset number of inhalations, it controls the drive module 13 to release the aerosol-generating base tape 30 to replace the aerosol-generating base tape 30 after atomization and prepare for the next atomization. The preset number of inhalations may be one or more, and may be set as necessary so that the aerosol-generating base tape 30 can be fully utilized.

[0058] In step S13, the real-time release length of the aerosol-generating substrate tape 30 is obtained.

[0059] Specifically, the supply detection module 16 acquires the real-time release length of the aerosol-generating substrate tape 30 under the control of the main control module 11 and provides feedback to the main control module 11 .

[0060] In step S14, when the real-time emission length reaches a first predetermined length, updating of the aerosol-generating base tape 30 is stopped.

[0061] Specifically, the main control module 11 compares the real-time emission length with the first predetermined length. When it determines that the real-time emission length of the aerosol-generating base tape 30 is the first predetermined length, it indicates that the aerosol-generating base tape 30 has been updated, and controls the drive module 13 to stop emission of the aerosol-generating base tape 30 to avoid waste of the aerosol-generating base tape 30. The first predetermined length is equal to or greater than the atomization length of the aerosol-generating base tape 30 in one atomization cycle.

[0062] The driving module 13 may periodically release and renew the aerosol-generating base tape 30 under the control of the main control module 11, or may continuously release the aerosol-generating base tape 30 until inhalation is completed under the control of the main control module 11. In the method of periodically releasing the aerosol-generating base tape 30 for renewal, the aerosol-generating base tape 30 may be renewed after a certain period of time has elapsed after being heated by the atomization module 14, which is advantageous for sufficient atomization of the aerosol-generating base tape 30. In a preferred embodiment, the time required for waiting for renewal after heating the aerosol-generating base tape 30 is 0.5 to 5 seconds.

[0063] Specifically, in one embodiment, step S13 of acquiring the real-time release length of the aerosol-generating base tape 30 specifically includes the following steps S131 to S132.

[0064] In step S131, the rotation angle or the number of rotations of the rotating member 162 is obtained.

[0065] Specifically, the electronic atomization device includes a supply detection module 16, which includes a rotating member 162, a sensing unit, and a detection unit. The movement of the aerosol-generating substrate tape 30 can drive the rotating member 162 to rotate synchronously, and the detection unit can obtain the rotation angle or the number of rotations of the rotating member 162 by calculating the number of passes of the sensing unit that rotates according to the rotating member 162.

[0066] In step S132, a real-time release length of the aerosol-generating substrate tape 30 is obtained based on the rotation angle or the number of rotations.

[0067] Specifically, since the emission length of the corresponding aerosol-generating base tape 30 is constant each time the rotating member 162 rotates by a unit angle, the supply detection module 16 can acquire the real-time emission length of the aerosol-generating base tape 30 based on the rotation angle or number of rotations and transmit it to the main control module 11.

[0068] Specifically, in another embodiment, step S13 of acquiring the real-time release length of the aerosol-generating base tape 30 specifically includes the following steps S133 to S134.

[0069] In step S133, the number of rotations of the motor encoder of the supply motor is obtained.

[0070] Specifically, the output shaft of the supply motor of the drive module 13 is brought into close contact with the aerosol-generating base tape 30, and the supply detection module 16 is connected to a motor encoder of the supply motor to obtain the number of rotations of the motor encoder of the supply motor.

[0071] In S134, the real-time release length of the aerosol-generating base tape 30 is obtained based on the number of rotations of the motor encoder.

[0072] Specifically, since the emission length of the corresponding aerosol-generating base tape 30 is constant each time the drive shaft of the supply motor rotates by a unit angle, the supply detection module 16 can obtain the real-time emission length of the aerosol-generating base tape 30 based on the number of rotations of the motor encoder and transmit it to the main control module 11.

[0073] Specifically, in one embodiment, step S13 of acquiring the real-time release length of the aerosol-generating base tape 30 specifically includes the following steps S135 to S136.

[0074] In step S135, the number of detection marks on the aerosol-generating base tape 30 is obtained.

[0075] Specifically, marking features are disposed on the aerosol-generating base tape 30, and a number of the marking features are spaced apart along the longitudinal direction of the aerosol-generating base tape 30, and as the aerosol-generating base tape 30 is released, the supply detection module 16 can acquire the number of the marking features.

[0076] In step S136, the real-time release length of the aerosol-generating base tape 30 is obtained based on the number of detection marks.

[0077] Specifically, since the distance between two adjacent marking features is constant, the main control module 11 can calculate the real-time release length of the aerosol-generating substrate tape 30 based on the number of detected marks.

[0078] In some embodiments, a method for controlling atomization includes: The method further includes the step of, after obtaining the activation signal, releasing a second predetermined length of the aerosol-generating substrate tape 30 in response to the activation signal.

[0079] Specifically, after the start / stop signal input module 12 obtains the start signal and feeds it back to the main control module 11, the main control module 11 controls the driving module 13 to release a second predetermined length of the aerosol-generating substrate tape 30 to replace the previously exposed aerosol-generating substrate tape 30, thereby ensuring the synchronism of the quality of the aerosol-generating substrate tape 30 and further improving the synchronism of each inhalation. Note that, the second predetermined length may be set according to the length of the aerosol-generating substrate tape 30 exposed to the outside, so as to realize the replacement of the aerosol-generating substrate tape 30.

[0080] In some embodiments, after the step S1 of receiving an activation signal and controlling the electronic atomization device to enter an atomization period in response to the activation signal, the method further comprises: The method further includes the step S2 of receiving a stop signal and releasing a third predetermined length of the aerosol-generating substrate tape in response to the stop signal.

[0081] Specifically, the device that obtains the start signal is the start / stop signal input module 12. Specifically, in one embodiment, when a user presses the start / stop signal input module 12, the start / stop signal input module 12 can obtain a stop signal and send it to the main control module 11. It should be noted that the manner in which the start / stop signal input module 12 obtains the start command is not limited, and the start / stop signal input module 12 may obtain the start signal accordingly through fingerprint recognition, touch recognition, airflow sensing, voice recognition, gesture recognition, etc.

[0082] In addition, in some embodiments, the main control module 11 can also obtain a stop signal by obtaining the operation time of the electronic atomization device, obtaining the operation temperature of the electronic atomization device, judging the remaining amount of the aerosol-generating base tape 30, etc. When the operation time of the electronic atomization device is too long, the operation temperature is too high, or the remaining amount of the aerosol-generating base tape 30 is too low, the main control module 11 can obtain a stop signal to stop the operation of the electronic atomization device in a timely manner, so as to prevent the electronic atomization device from failing due to factors such as too long operation time, too high temperature, and dry burning.

[0083] After the driving module 13 receives the stop signal, controlling the electronic atomization device to stop operating includes stopping the acquisition of the number of inhalations, controlling the atomization module 14 to stop heating the aerosol-generating base tape 30, controlling the driving module 13 and the supply detection module 16 to stop operating, and controlling the status indication module 17 to send a signal to indicate the operating status of the electronic atomization device.

[0084] Specifically, because the atomized aerosol-generating base tape 30 becomes thinner and more prone to breakage, before controlling the electronic atomization device to stop operating, the main control module 11 controls the drive module 13 to release a first predetermined length of aerosol-generating base tape 30 to replace the heated and atomized aerosol-generating base tape 30, thereby reducing breakage of the aerosol-generating base tape 30.

[0085] The above-mentioned atomization control method and atomization device utilize the strip-shaped aerosol-generating base tape 30 to realize an instant inhalation / stop function, i.e., when a user uses an electronic atomization device, the aerosol-generating base tape 30 can be quickly heated to generate aerosol, and when the user stops inhaling, the heating can be stopped in a timely manner to avoid wasting the aerosol-generating base tape 30 and improve the utilization rate of the aerosol-generating base tape 30. In addition, by providing the supply detection module 16, the emission length of the aerosol-generating base tape 30 can be detected in real time, so that the emission amount of the aerosol-generating base tape 30 can be accurately controlled and the synchronization of inhalation can be improved.

[0086] The technical features of the above-mentioned embodiments can be combined in any combination. For the sake of brevity, all combinations of the technical features in the above-mentioned embodiments are not described, but the combinations of these technical features should be considered within the scope described in this specification unless they are inconsistent.

[0087] The above examples merely show some embodiments of the present application, and although the description is specific and detailed, it should not be construed as limiting the scope of protection of the invention. It should be noted that those skilled in the art can make some modifications and improvements without departing from the spirit of the present application, and all of these are within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be in accordance with the claims. [Explanation of symbols]
