The application will be described in detail below in conjunction with the accompanying drawings and embodiments.

Please refer to FIG. 1 . FIG. 1 provides a cross-sectional view of an aerosol matrix structure provided by the present application. In this embodiment, the aerosol matrix structure 100 (shown in FIG. 16 ) includes a matrix section 111 , an airway section 112 and a filter section 113 which are sequentially connected and air communicated with each other. In the present application, the matrix segment 111 , the airway segment 112 and the filter tip segment 113 refer to the shell of each functional segment of the aerosol matrix structure 100 , and other components are further arranged inside.

Specifically, the substrate segment 111 has a cavity 111d inside, and the cavity 111d is used for accommodating the aerosol generating substrate 120, such as grass leaves or flowers of a plant. In one embodiment, the matrix segment 111 can be a tubular body formed by surrounding the side wall, such as a circular tube with one end being a closed end and the other end being an open end, in which a cavity 111d is formed, and the aerosol generating matrix 120 is set In the cavity 111d , the open end of the matrix segment 111 is a first opening 111b , and the first opening 111b communicates with the airway segment 112 .

Wherein, in this embodiment, the substrate segment 111 can also be used as a heating element to generate heat through electromagnetic induction, so as to heat the aerosol generating substrate 120 inside it. Wherein, the sidewall of the matrix segment 111 can be made of metal material, and a metal material layer can also be provided on the inner surface or the outer surface of the sidewall of the matrix segment 111 . In this embodiment, the aerosol generating substrate 120 can be in direct contact with the inner surface of the substrate segment 111, so that the heat generated by the substrate segment 111 can be directly transferred to the aerosol generating substrate 120, and the heat does not need to be transferred in the air medium, which can reduce the heat. Heat loss during transfer.

In one embodiment, in order to realize the heating of the sidewall of the matrix section 111 through electromagnetic induction, the material of the matrix section 111 is a ferromagnetic material with a Curie point temperature. Below the Curie point temperature, the ferromagnetic material is ferromagnetic, and can continue to generate heat through electromagnetic induction under the action of the oscillating coil, so as to realize the heating and baking of the aerosol generating substrate 120; after exceeding the Curie point temperature, the ferromagnetic material Transform from ferromagnetism to paramagnetism, that is, at this time, the side wall of the matrix segment 111 is no longer magnetic, stop the electromagnetic induction heating of the aerosol-generating matrix 120, and precisely control the temperature of the aerosol-generating matrix 120 within a certain temperature range In this way, the heating temperature of the aerosol generating substrate 120 is prevented from being too high, and problems such as burning of the aerosol generating substrate 120 occur, so that the temperature of the aerosol generating substrate 120 can be precisely controlled.

An air inlet 142 is opened on the side wall of the air channel section 112 , and the air inlet 142 is spaced apart from the matrix section 111 . That is, the air inlet 142 is opened in the middle of the airway section 112 near the side of the matrix section 111 , and has a certain distance from the matrix section 111 . Because the side wall of the matrix section 111 heats the aerosol generating matrix 120, the temperature of the airflow close to the matrix section 111 will increase, which in turn will cause the temperature of the aerosol formed by the aerosol generating matrix 120 to increase, and the air inlet 142 will Set in the middle of the airway section 112 close to the end of the matrix section 111 and have a certain distance to ensure that when the sidewall of the matrix section 111 is heated to generate the aerosol matrix 120, the impact of the sidewall of the matrix section 111 on the airway section can be reduced to a certain extent. The influence of the airflow temperature in 112 keeps the airflow temperature from being too high, which improves the user's experience when inhaling.

In addition, in this embodiment, the airflow entering the air passage section 112 through the air inlet hole 142 only passes through the first opening 111b of the cavity 111d and does not enter the cavity 111d. Multiple air intake holes 142 can be provided, and multiple air intake holes 142 are arranged circumferentially along the side wall of the air passage section 112. To a certain extent, this design can make the amount of aerosol sucked relatively sufficient, and the suction resistance is moderate. And the temperature of the airflow is moderate, so that the user's suction experience is better. Wherein, the shape of the air inlet 142 can be circular, elliptical, rhombus, square, etc., and is selected according to the production process and cost of the aerosol matrix structure 100, which is not limited here.

Please refer further to FIG. 2 , the airway section 112 is provided with a guiding body 122, and a first suction channel 122d is opened in the guiding body 122, and the first suction channel 122d communicates with the cavity 111d, and the side wall of the guiding body 122 is in contact with the air A guide channel 132 is formed between the inner surfaces of the road sections 112, and the guide channel 132 communicates with the cavity 111d, and the guide channel 132 is used to guide the airflow entering the air inlet 142 to the end of the cavity 111d near the guide body 122, To take away the aerosol at the first opening 111b.

At the first opening 111b, the airflow carries the aerosol and then flows into the first suction channel 122d, and finally passes through the filter section 113 for the user to inhale. During this process, the guide channel 132 can change the direction of the airflow entering the airway section 112, so that the airflow rushes to the first opening 111b of the cavity 111d, increasing the turbulence of the airflow at the first opening 111b, making more The aerosol diffuses to the first opening 111b to take away more aerosol to the filter section 113, increasing the amount of aerosol inhaled by the user at one time, thereby improving the experience of the user.
