Moreover, under the action of the one-way valve 50, the third airway 33 can be effectively closed in the preheating mode to ensure the normal use of the preheating mode. In the atomization mode, due to the user's exposure to the aerosol in the storage chamber The suction action of forming the matrix causes an air pressure difference to exist on both sides of the one-way valve 50, causing the one-way valve 50 to open and the third airway 33 to be in an open state.

After the preheating mode, when starting to use the atomization mode of the thermal structure of the atomizer, due to the reduction of endothermic substances (water molecules) in the aerosol-forming matrix, the power consumption is reduced, and at the same time, the heating element 10 can be quickly heated up. With the heating atomization effect, the remaining substances (such as various tobacco components) in the aerosol-forming matrix can also be heated and atomized more quickly, producing an aerosol that can be smoked by the user.

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

As shown in FIG. 2 , the heat-not-burn atomizer also includes a bracket 110 . A control panel 120 is installed on one side of the bracket 110 , and an airflow generating device 40 is installed on the other side of the bracket 110 . Specifically, as shown in FIG. 1 , the bracket 110 includes a bracket main body 111 and a mounting body 112 . The mounting body 112 is provided with a mounting slot 113 , and the airflow generating device 40 is mounted on the mounting slot 113 . The mounting body 112 may be an integral structure with the bracket body 111 , or the mounting body 112 may be detachably fixed on the bracket 110 . 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 air flow generating device 40 is connected with the second air channel 32, and the air inlet end of the air flow generating device 40 is arranged in the housing 150 that heats the non-combustible atomized gas. For example, the installation groove 113 can be provided with a semicircular slot and a rectangular groove. The semicircular slot is used to clamp the air inlet end of the air flow generating device 40, and the rectangular slot is used to clamp and fix it. The main body of the airflow generating device 40 . The shapes mentioned here are only examples and should not be construed as limitations of the present application.

As shown in FIG. 2 , the control board 120 is electrically connected to the heating element 10 and the air flow generating device 40 respectively. The control panel 120 is configured to successively activate the heating assembly and the airflow generating device 40 in the preheating mode, first preheat the aerosol-forming matrix inside the heating assembly, and then discharge the aerosol through the flowing airflow generated by the airflow generating device 40 Water vapor is formed by heating the substrate. In the atomization mode, the control panel 120 is used to activate the heating element 10 to heat and atomize the aerosol-forming matrix in the heating element 10 .

Among them, if the heating element 10 acts as a heating element by itself, for example, the heating element 10 itself has a resistive structure, the control board 120 can be directly electrically connected to the heating element 10. If the heating element 10 needs to generate heat indirectly through a heating element, the control board 120 can 120 is indirectly electrically connected to the heating element 10 through the heating element. The control panel 120 can facilitate the phased control of the preheating mode and the atomization mode in the atomization heating structure, and facilitate the selection of one of the working modes. In the preheating mode, the heating element 10 is started first, and the aerosol-forming matrix in the storage cavity can be preheated first. In this way, the airflow generating device 40 is started after a period of time, and the airflow can be directly directed to the airflow with a relatively high flow rate. Water vapor within the aerosol-forming matrix is rapidly expelled from the aerosol-forming matrix. If the heating element 10 and the air flow generating device 40 are started simultaneously in the preheating mode, some water molecules in the aerosol-forming matrix may not be evaporated and cannot be discharged. Therefore, through the control function of the control board 120, the heating element 10 and the air flow generating device 40 are started in stages in the preheating mode, which can better ensure the water vapor discharge effect.

More preferably, as shown in Figure 2, it also includes a switch key 130, a timer, a battery 140 and a housing 150. The switch key 130 and the battery 140 are electrically connected to the control board 120 respectively. The switch key 130 is used to change the working state of the heating component through the control board 120 . The switch key 130 is also used to start or stop the timing function of the timer. The timer is used to send startup information or shutdown information to the control panel 120 by timing according to a preset time period. The control panel 120 is used to activate the air flow generating device 40 according to the startup information. The control board 120 is also used to shut down the air flow generating device 40 according to the shutdown information. The timer may be an independent device, or the timer may 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 switch key 130 and the control board 120 respectively. The atomization heating structure, bracket 110, control panel 120, switch key 130, etc. are all arranged in the outer shell 150, and the outer shell 150 protects the internal structure.

Taking the heating element 10 in the preheating mode to work for 5 seconds first, and then the airflow generating device 40 to start working for 10 seconds as an example, the specific working principle of the heat-not-burn atomizer is explained: When the user uses the heat-not-burn atomizer, the user opens the Insert the prepared aerosol forming matrix. When the switch key 130 is operated, the switch key 130 sends an action signal to the control board 120, and the control board 120 starts the heating element 10 according to the received action signal. At the same time, the switch key 130 sends the action signal to the timer, and the timer starts timing according to the received action signal. When the timer reaches 5 seconds, start-up information is sent to the control board 120. The control board 120 starts the air flow generating device 40 according to the received start information, and the air flow generating device 40 starts working. When the timer reaches 15 seconds, that is, after the air flow generating device 40 has been working for 10 seconds, the timer sends a shutdown message to the control board 120, and the control board 120 closes the air flow generating device 40 according to the received shutdown message. At this time, the air flow generating device 40 stops working and the preheating mode ends. After the airflow generating device 40 stops working, the heating element 10 continues to work, and the heat-not-burn atomizer enters the atomization mode. At this time, the user can normally inhale the aerosol to form a matrix. When the user stops inhaling the aerosol-forming substrate, or after one of the aerosol-forming substrates is exhausted, the switch key 130 is operated again. The switch key 130 sends an action signal to the control panel 120, and the control panel 120 is closed according to the action signal received again. The heating element 10 and the heat-not-burn atomizer stop working at this time.

When the heat-not-burn atomizer designed in this application works, it first works in the preheating mode, and then works in the atomizing mode. When actually using a heated non-burning atomizer, after the preheating mode ends, you can also pump the aerosol-forming matrix after an interval of 2-3 seconds, so as to fully discharge the water vapor in the aerosol-forming matrix. When users actually use the heat-not-burn atomizer, they can judge when the product (i.e. the heat-not-burn atomizer) is in the atomization mode according to the accompanying product instructions. Alternatively, in other embodiments, the heat-not-burn atomizer may also be provided with an indicator light on the housing 150, for example, to determine the working mode of the heat-not-burn atomizer by the color of the indicator light. In other embodiments, in addition to setting a common switch key 130, a corresponding number of switch keys 130 can also be set according to the working mode type of the heat-not-burn atomizer, such as setting a preheating switch and an atomization switch. Use the preheating switch to start or stop the preheating mode, and use the atomizing switch to start or stop the atomizing mode. When the preheating switch is set, the preheating switch is electrically connected to the timer, and the atomizing switch is equivalent to the originally set switch key 130, but at this time the atomizing switch no longer needs to be electrically connected to the timer. In the preheating mode, the specific working time of the heating element 10 and the air flow generating device 40 is set according to actual needs and is not limited in this application.

Under the user's suction, an air pressure difference is formed on both sides of the one-way valve 50, and then the one-way valve 50 is opened, so that the third airway 33 is in conductive state. If the user stops puffing in the atomization mode, the one-way valve 50 will also be in a closed state. Similarly, in the preheating mode, since the user does not puff, the one-way valve 50 will be in the preheating state. It will also be turned off in mode and will not affect the normal operation of preheating mode. The designed atomization heating method is based on the heat-not-burn atomizer in the above embodiment. By discharging the water vapor in the aerosol-forming matrix in the preheating mode, it effectively solves the problem of burning the mouth when using the atomization mode subsequently. problems and improve user experience.
