[0002] Heat-not-burn atomizers primarily heat and atomize the aerosol-forming matrix through their atomizing heating structure. Typically, the aerosol-forming matrix contains not only some of the atomized components but also a certain amount of water molecules. Therefore, when heating the aerosol-forming matrix, in addition to heating the atomized components, the water molecules within it are inevitably heated. The heated water molecules turn into water vapor, which flows toward the user's mouth as the user draws. Once the water vapor enters the user's mouth, it liquefies and releases heat, causing a mouthburn, which is particularly noticeable during the user's first puff.

References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).

[0032] As shown in Figures 1-5, an embodiment of the present application provides an atomizing heating structure, comprising: a heating component and an airflow generating device 40. The heating component is used to accommodate and heat an aerosol-forming substrate, and the heating component forms a storage cavity for storing the aerosol-forming substrate. The air outlet end 41 of the airflow generating device 40 is connected to the storage cavity. The atomizing heating structure has a preheating mode, and the airflow generating device 40 is configured to provide a flowing airflow to the aerosol-forming substrate in the storage cavity in the preheating mode to drive the gas flow in the aerosol-forming substrate and discharge the water vapor generated by heating the aerosol-forming substrate.

[0033] The atomizing and heating structure of the above-described embodiment is employed, with an airflow generating device 40 provided, with an air outlet 41 of the airflow generating device 40 communicating with the storage chamber. Furthermore, in the preheating mode of the atomizing and heating structure, the airflow generating device 40 is configured to provide a flowing airflow to the aerosol-forming substrate within the storage chamber, thereby driving the flow of gas within the aerosol-forming substrate and discharging water vapor generated by the heated aerosol-forming substrate, effectively resolving the mouthburning problem that occurs when heating the atomized aerosol-forming substrate.

[0034] Specifically, the airflow generating device 40 is an air pump, a fan or other device that can generate flowing airflow. The flow rate of the flowing airflow is set according to actual needs and is not limited in this application.

[0035] As shown in Figures 1 and 4-5, the atomizing heating structure also includes an air duct connecting piece 30, in which a first air duct 31, a second air duct 32 and a third air duct 33 are provided. The second air duct 32 and the third air duct 33 are both connected to the first air duct 31, the first air duct 31 is connected to the receiving chamber, the second air duct 32 is connected to the air outlet end 41 of the air flow generating device 40, and the third air duct 33 is connected to the outside world. The second air duct 32 and the third air duct 33 can be isolated from each other or in a connected state. The air outlet end 41 of the air flow generating device 40 can be directly connected to the air duct connecting piece 30 at the second air duct 32 for a simplified structure.

[0036] As shown in Figure 1, the atomizing and heating structure also includes an airway tube 60, and the third airway 33 is connected to the outside world through the airway tube 60. Specifically, the airway tube 60 can be directly connected to the airway connecting piece 30 where the third airway 33 is provided, so as to directly connect the airway tube 60 and the third airway 33. One end of the airway tube 60 away from the airway connecting piece 30 can be used to abut against the air inlet of the upper shell 150 of the heat-not-burn atomizer, and connect the airway tube 60 and the air inlet. In other embodiments, the airway tube 60 may not be provided separately, but a tube directly extends from the airway connecting piece 30 to abut against the air inlet on the shell 150 to serve as the airway tube 60.

[0037] As shown in Figures 1 and 3, in an embodiment of the present application, the atomizing and heating structure further includes a one-way valve 50, which is arranged in the third air duct 33. Specifically, the one-way valve 50 is arranged in the third air duct 33 near one end of the air duct tube 60, and the end of the air duct tube 60 is sleeved with the one-way valve 50. The air duct tube 60 can be sleeved on the inner side of the one-way valve 50, or on the outer side of the one-way valve 50, which is specifically determined according to the structural dimensions. The one-way valve 50 is arranged in the third air duct 33 near one end of the air duct tube 60, which is also convenient for assembly and connection with the air duct tube 60. Specifically, the one-way valve 50 includes a valve body 51 and a valve cover 52, the valve body 51 and the air duct tube 60 are sleeved, and the valve cover 52 and the valve body 51 are hinged or rotatably connected.

[0038] More preferably, the atomizing and heating structure further includes a liquid storage component (not shown), which is provided with a liquid storage cavity. The liquid storage cavity is used to collect substances produced after the aerosol condenses and liquefies in the storage cavity, such as the tobacco oil produced after the aerosol-forming matrix is ​​heated and atomized. One end of the liquid storage component is connected to the heating component, and the other end is connected (sleeved) to the airway connecting component 30. The two ends of the liquid storage cavity are respectively connected to the storage cavity and the first airway 31. Specifically, the liquid storage component includes a liquid storage tank and a sealing seat. The sealing seat is fixed to the end of the liquid storage tank away from the heating component, and the liquid storage tank and the sealing seat enclose a liquid storage cavity. A connecting pipe is provided on the sealing seat, and a portion of the connecting pipe is located in the liquid storage cavity, while the other portion is located outside the liquid storage cavity. The connecting pipe and the airway connecting component 30 are sleeved. By setting up the liquid storage component, the atomization heating structure also has the function of collecting smoke oil without interfering with the preheating mode and atomization mode of the atomization heating structure, thereby avoiding the pollution problem caused by the liquid substance generated after the aerosol-forming matrix is ​​heated and atomized and flowing around.

[0039] The heating assembly includes a heating element 10 and a base 20. The heating element 10 is used to heat the aerosol-forming matrix. The base 20 is provided at one end of the storage chamber close to the airflow generating device 40. A transit air duct connected to the storage chamber is formed on the base 20. The transit air duct is also connected to the air outlet 41 of the airflow generating device 40. Among them, the heating element 10 can be a peripheral heating body, a central heating body, or a hot air flow heating body. The peripheral heating body can include a thick film tube, an infrared heating tube, an electromagnetic induction heating tube, etc.; the central heating body can include a heating needle, a heating rod, a heating sheet, and an electromagnetic induction central heating body, etc.; the hot air flow heating body is provided at one end of the storage chamber close to the airflow generating device 40, and is provided with a plurality of air ducts for heating the air. For example, it can be a honeycomb, a porous body, etc., and can adopt electromagnetic induction heating, peripheral resistance coating heating, heating wire heating, and other heating methods. The specific form of the heating element 10 can be flexibly selected according to actual needs, and this application does not impose any restrictions. When the base 20, the airway connecting piece 30 and the liquid storage piece are set, one end of the base 20 is connected to the heating element 10, and the other end is connected to the liquid storage piece. The end of the liquid storage piece away from the base 20 is connected to the airflow connecting piece 30 provided with the first airway 31.

[0040] As shown in Figures 1-2, the atomizing heating structure also includes a sleeve 70, which is sleeved on the outside of the heating element 10, and the sleeve 70 effectively protects the heating element 10 therein. Specifically, the atomizing heating structure also includes a pre-tightening ring 80, a sealing ring 90 and a thermal insulation member 100. The pre-tightening ring 80 is arranged at the top of the sleeve 70, and the inner side of the pre-tightening ring 80 is used to contact the periphery of the aerosol-forming matrix to provide pre-tightening and support for the aerosol-forming matrix. The sealing ring 90 is arranged at the bottom end of the sleeve 70, and the two sides of the sealing ring 90 are respectively in contact with the inner wall of the sleeve 70 and the periphery of the base 20 to play a sealing role. The sealing ring 90 effectively ensures the sealing of the space between the sleeve 70 and the heating element 10, providing a better thermal insulation environment for the heating element 10. The top end of the sleeve 70 and the leading end of the heating element 10 are on the same side, while the bottom end of the sleeve 70 and the trailing end of the heating element 10 are on the same side. The preload ring 80 and the sealing ring 90 can both be made of silicone based on their functions. The thermal insulator 100, similar to a reflective heat-insulating film, is fixed to the inner wall of the sleeve 70. This protects the heating environment of the heating element 10 and reduces unnecessary heat loss.

[0041] The atomizing and heating structure is provided with an airway connecting member 30, an airflow generating device 40, and a one-way valve 50, so that the atomizing and heating structure has two airways connected to the storage chamber. One airway is used in preheating mode, and the other airway is used in atomization mode. Specifically, when the airflow generating device 40 is operating in preheating mode, the airflow generated by the airflow generating device 40 flows into the aerosol-forming matrix through the second airway 32, the first airway 31, the transit airway, and the storage chamber in sequence, and discharges the water vapor generated by the heating of the aerosol-forming matrix. This effectively reduces the water vapor content flowing into the mouth when the user inhales the aerosol-forming matrix in the subsequent atomization mode, thereby solving the problem of burning the mouth due to the heat released by the liquefied water vapor. Furthermore, the one-way valve 50 effectively closes the third air passage 33 in preheating mode, ensuring normal operation. In atomization mode, the user's inhalation of the aerosol-forming substrate within the storage chamber creates a pressure differential across the one-way valve 50, causing it to open and the third air passage 33 to remain open. This atomization and heating structure effectively removes water molecules from the aerosol-forming substrate before inhalation, effectively resolving the mouth-burning issue.

[0042] The atomizing heating structure of the aforementioned embodiment is designed to rapidly expel water vapor generated within the aerosol-forming matrix by combining the heating effect of the heating element 10 with airflow generated at a preset flow rate by the airflow generating device 40 in the preheating mode. This effectively reduces water vapor flowing out of the aerosol-forming matrix during the subsequent atomization mode, alleviating or resolving the mouthburning problem. To quickly expel water vapor from the aerosol-forming matrix during the preheating mode, the airflow generating device 40 can generate an airflow at a relatively high flow rate. After the preheating mode, when the atomizing mode of the atomizer thermal structure is initiated, power consumption is reduced due to the reduction of heat-absorbing substances (water molecules) within the aerosol-forming matrix. This also allows the heating element 10 to rapidly heat up, achieving a heating and atomizing effect. Remaining substances within the aerosol-forming matrix (e.g., various tobacco components) can also be heated and atomized more quickly, producing an aerosol suitable for inhalation by the user.

[0043] As shown in FIG. 2 , another embodiment of the present application provides a heat-not-burn atomizer, comprising a control board 120 and the atomization heating structure in the above embodiment, wherein the control board 120 is electrically connected to the airflow generating device 40 .

[0044] As shown in Figure 2, the heat-not-burn atomizer also includes a bracket 110, a control panel 120 is mounted on one side of the bracket 110, and an airflow generating device 40 is mounted on the other side of the bracket 110. Specifically, as shown in Figure 1, the bracket 110 includes a bracket body 111 and a mounting body 112, and the mounting body 112 is provided with a mounting groove 113, and the airflow generating device 40 is mounted on the mounting groove 113. The mounting body 112 can be an integral structure with the bracket body 111, or the mounting body 112 can be fixed to the bracket 110 in a detachable manner. The shape of the mounting groove 113 provided on the mounting body 112 is adapted to the structure of the airflow generating device 40, so as to firmly fix the airflow generating device 40. The air outlet end 41 of the airflow generating device 40 is connected to the second air duct 32, and the air inlet end of the airflow generating device 40 is provided in the housing 150 of the heat-not-burn atomizer. For example, the mounting slot 113 may be provided with a semicircular slot and a rectangular slot, with the semicircular slot being used to engage the air inlet end of the airflow generating device 40, and the rectangular slot being used to engage and secure the main body of the airflow generating device 40. The shapes described herein are merely illustrative and should not be construed as limiting the present application.

[0045] As shown in Figure 2, the control board 120 is electrically connected to the heating element 10 and the airflow generating device 40, respectively. In preheating mode, the control board 120 is configured to sequentially activate the heating component and the airflow generating device 40, first preheating the aerosol-forming substrate therein via the heating component, and then discharging the water vapor formed by the heated aerosol-forming substrate via the flowing airflow generated by the airflow generating device 40. In atomization mode, the control board 120 activates the heating element 10 to heat and atomize the aerosol-forming substrate therein.

[0046] Among them, if the heating element 10 acts as a heating element by itself, for example, the heating element 10 itself is a resistor structure, then the control board 120 can be directly electrically connected to the heating element 10. If the heating element 10 needs to indirectly generate heat through the heating element, then the control board 120 is indirectly electrically connected to the heating element 10 through the heating element. Through the control board 120, it is easy to realize the staged control of the preheating mode and the atomization mode in the atomization heating structure, so as to select one to realize its working mode. In the preheating mode, the heating element 10 is started first, and the aerosol-forming matrix in the storage chamber can be preheated first. In this way, after a period of time, the airflow generating device 40 is started again, and the water vapor in the aerosol-forming matrix can be directly discharged quickly from the aerosol-forming matrix with an airflow of relatively high flow rate. If in the preheating mode, the heating element 10 and the airflow generating device 40 are started at the same time, the phenomenon that some water molecules in the aerosol-forming matrix have not been vaporized and cannot be discharged may occur. Therefore, through the control function of the control board 120, the heating element 10 and the airflow generating device 40 are started in stages in the preheating mode, which can better ensure the water vapor discharge effect.

[0047] More preferably, as shown in Figure 2, it also includes an on / off key 130, a timer, a battery 140, and a housing 150. The on / off key 130 and the battery 140 are electrically connected to the control board 120 respectively. The on / off key 130 is used to change the operating state of the heating component through the control board 120. The on / off key 130 is also used to start or stop the timing function of the timer. The timer is used to send a start message or a shutdown message to the control board 120 by timing according to a preset time period. The control board 120 is used to start the airflow generating device 40 according to the start message, and the control board 120 is also used to shut down the airflow generating device 40 according to the shutdown message. The timer can be an independent device, or the timer can be a module with a timing function on the control board 120. When the timer is an independent device, the timer is electrically connected to the on / off key 130 and the control board 120 respectively. The atomizing heating structure, the bracket 110, the control board 120, the on / off key 130, etc. are all arranged in the housing 150, and the housing 150 protects the internal structures.

[0048] Taking the example of a heat-not-burn atomizer in which the heating element 10 first operates for 5 seconds in preheat mode, followed by the airflow generating device 40 activating and operating for 10 seconds, the specific operating principle of the heat-not-burn atomizer will be explained: When a user uses the heat-not-burn atomizer, they insert the prepared aerosol-forming substrate into the storage chamber. They then operate the switch 130, which sends an action signal to the control panel 120. The control panel 120 activates the heating element 10 based on the action signal received. Simultaneously, the switch 130 sends the action signal to a timer, which begins counting based on the action signal received. When the timer reaches 5 seconds, it sends a start message to the control panel 120. Based on the received start message, the control panel 120 activates the airflow generating device 40, and the airflow generating device 40 begins operating. When the timer reaches 15 seconds, meaning that the airflow generating device 40 has operated for 10 seconds, the timer sends a shutdown message to the control panel 120. Based on the shutdown message received, the control panel 120 shuts down the airflow generating device 40, and the airflow generating device 40 ceases operation, ending the preheat mode. After the airflow generating device 40 stops operating, the heating element 10 continues to operate, and the heat-not-burn atomizer enters atomization mode, allowing the user to inhale the aerosol-forming substrate normally. When the user stops inhaling the aerosol-forming substrate, or when a stick of aerosol-forming substrate is completely inhaled, the user again operates the switch 130. The switch 130 sends an action signal to the control board 120. The control board 120 then turns off the heating element 10 based on the received action signal, and the heat-not-burn atomizer stops operating.

[0049] The heat-not-burn atomizer designed in this application operates first in preheating mode and then in atomization mode. During actual use, after the preheating mode ends, the aerosol-forming substrate can be puffed again for 2-3 seconds to fully expel the water vapor within the aerosol-forming substrate. When using the heat-not-burn atomizer, users can refer to the accompanying product manual to determine when the product (i.e., the heat-not-burn atomizer) is in atomization mode. Alternatively, in other embodiments, the heat-not-burn atomizer may include an indicator light on the housing 150, such as by the color of the indicator light, to indicate the operating mode of the heat-not-burn atomizer. In other embodiments, in addition to providing a common on / off switch 130, a corresponding number of on / off switches 130 may be provided depending on the operating mode of the heat-not-burn atomizer, such as a preheating switch and an atomization switch, with the preheating switch used to activate or deactivate the preheating mode and the atomization switch used to activate or deactivate the atomization mode. When the preheat switch is set, the preheat switch is electrically connected to the timer. The atomization switch is equivalent to the previously set on / off switch 130, but in this case, the atomization switch no longer needs to be electrically connected to the timer. In the preheat mode, the specific operating time of the heating element 10 and the airflow generating device 40 can be set according to actual needs and is not limited in this application.

[0050] In another embodiment of the present application, an atomization heating method is provided. Based on the above-mentioned heat-without-combustion atomizer, the atomization heating method includes:

[0051] The aerosol-forming matrix in the receiving cavity is first preheated by the preheating mode, and then the aerosol-forming matrix in the receiving cavity is heated and atomized by the atomization mode after the preheating mode is completed.

[0052] In the preheating mode, the heating component is first activated to heat the aerosol-forming substrate in the storage chamber, and then the airflow generating device 40 is activated to generate an airflow with a preset flow rate through the airflow generating device 40 to discharge the water vapor generated by the heating of the aerosol-forming substrate.

[0053] In the atomization mode, the airflow generating device 40 is turned off, the heating component continues to maintain the heating effect on the aerosol-forming substrate in the receiving chamber, the one-way valve 50 is opened, and airflow is provided to the aerosol-forming substrate in the receiving chamber through the third air channel 33.

[0054] To prevent mouth burns, the user inhales the aerosol-forming matrix in atomization mode. Under the user's inhalation, an air pressure difference forms on both sides of the one-way valve 50, thereby opening the one-way valve 50 and placing the third airway 33 in a conductive state. If the user stops inhaling in atomization mode, the one-way valve 50 will also be closed. Similarly, in preheating mode, since the user does not inhale, the one-way valve 50 will also be closed in preheating mode, which will not affect the normal operation of the preheating mode. The designed atomization heating method is based on the heat-without-combustion atomizer of the above-mentioned embodiment. By discharging water vapor in the aerosol-forming matrix in preheating mode, it effectively solves the mouth burn problem caused by subsequent use of the atomization mode and improves the user experience.

[0055] The above specific examples are used to illustrate the present application, which is only used to help understand the present application and is not intended to limit the present application. For those skilled in the art of the present application, based on the concept of the present application, they can also make some simple deductions, modifications or substitutions.
