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 100 according to a first embodiment of the present application. In this embodiment, an aerosol matrix structure 100 is provided. The aerosol matrix structure 100 includes a matrix section 111 , an airway section 112 and a filter section 113 connected in sequence.

The substrate segment 111 includes an aerosol generating substrate 120 and a heat generating body 121 . The heating element 121 has a closed cavity 111d, and the closed cavity 111d is used to accommodate the aerosol generating substrate 120, that is, the aerosol generating substrate 120 is disposed in the closed cavity 111d of the heating element 121, and one end of the closed cavity 111d has a first opening 111b. Specifically, the side wall of the heating element 121 is ring-shaped to form a tubular body, and the end of the tubular body connected to the airway section 112 is an open end. In this embodiment, the open end serves as the first opening 111b. It should be noted that when the open end is used as the first opening 111b, the diameter of the first opening 111b is consistent with the diameter of the closed cavity 111d. Certainly, in its embodiment, the caliber of the first opening 111b may be smaller than the caliber of the closed cavity 111d.

The airway section 112 is used to draw aerosols formed in the matrix section 111 . The airway section 112 is arranged at one end of the matrix section 111 having the first opening 111b, and the interior of the airway section 112 has a suction channel 112a, and the suction channel 112a communicates with the closed cavity 111d of the matrix section 111 through the first opening 111b.

The filter section 113 communicates with the end of the suction channel 112a of the airway section 112 away from the matrix section 111, so that the aerosol in the suction channel 112a can enter the filter section 113, thereby sucking the airway section 112 through the filter section 113. Inhaled aerosols are filtered. Specifically, the filter section 113 can be arranged on the side of the airway section 112 away from the matrix section 111, and the filter section 113 can be filled with a filter medium 114, which can filter tar and suspended particles in the aerosol, The aerosol drawn by the airway segment 112 is filtered through the filter medium 114 to reduce unwanted substances in the aerosol inhaled by the user. Wherein, the material of the filter medium 114 may be acetate fiber. Further, the end of the filter section 113 facing away from the air passage section 112 has a second opening 113a, so that the inner space of the filter section 113 communicates with the outside atmosphere. The user can inhale the aerosol from the end of the filter segment 113 having the second opening 113a.

Wherein, the air passage section 112 and the filter section 113 can be made of paper-based or foil-based materials. The material of the heating element 121 can include a ferromagnetic material with a Curie point temperature, and the ferromagnetic material can be, for example, an iron-nickel alloy, so that the ferromagnetic material with a Curie point temperature on the heating element 121 can generate heat through electromagnetic induction, thereby heating and The aerosol-generating substrate 120 inside is atomized to form an aerosol. Specifically, an electromagnetic coil can be wound around the periphery of the matrix segment 111 in a circumferential direction, so as to generate a magnetic field when the electromagnetic coil is energized, so that the ferromagnetic material with a Curie point temperature on the heating element 121 generates heat.

Wherein, the material of the heating element 121 includes a ferromagnetic material with a Curie point temperature means: the material of the heating element 121 can only be a ferromagnetic material with a Curie point temperature, and the heating element 121 is all used as a heating element to generate a substrate for the aerosol 120 heat. Of course, the material of the heating element 121 may also include ferromagnetic materials with a Curie point temperature and other materials except the ferromagnetic materials with a Curie point temperature, and the other materials are only the same as the ferromagnetic materials with a Curie point temperature. It is a physical combination, that is, ferromagnetic materials do not chemically react with other materials.

Compared with the prior art where the heating element is arranged in the heating device, the heat generated by the heating element is conducted to the aerosol generating substrate 120 through a series of media, such as air and paper material wrapped around the aerosol generating substrate 120. Embodiment The aerosol generating substrate 120 is set in the heating element 121 made of a ferromagnetic material with a Curie point temperature, and the heating element 121 can be directly used as a heating element to generate heat through electromagnetic induction to generate heat for the aerosol inside the heating element 121. Substrate 120 is heated. The heat is directly transferred from the heating element 121 to the aerosol generating substrate 120, reducing the heat transfer medium, thereby reducing heat loss during heat conduction.

In addition, since the heating element 121 is heated by a ferromagnetic material with a Curie point temperature, and the ferromagnetic material with a Curie point temperature is below the Curie point temperature, the ferromagnetic material is ferromagnetic and can Under the action of the oscillating coil, the electromagnetic induction heats up continuously, so as to realize the heating and baking of the aerosol generating substrate 120 . However, after exceeding the Curie point temperature, the ferromagnetic material transforms from ferromagnetism to paramagnetism, that is, the heating element 121 no longer has magnetism at this time, and the heating element 121 stops electromagnetically inductively heating the aerosol generating substrate 120, thereby making the aerosol generating substrate 120 The heating element 121 can automatically stop heating when the heating temperature exceeds the Curie point temperature, so as to accurately control the temperature of the aerosol-generating substrate 120 within a certain temperature range, and prevent the heating temperature of the aerosol-generating substrate 120 from being too high, resulting in gas The aerosol generating substrate 120 is scorched and the like, so that the temperature of the aerosol generating substrate 120 can be precisely controlled, thereby eliminating the need for additional temperature measuring components in the heating device, effectively reducing production costs.

Furthermore, compared with the above-mentioned aerosol matrix structure 100 in which the aerosol-generating matrix 120 is wrapped with paper materials, this embodiment uses a heating element 121 to wrap the aerosol-generating matrix 120, which can further prevent baking during the suction process. The taste of paper improves the user's taste of smoking.

In one embodiment, at least one side of the heating element 121 facing the aerosol generating substrate 120 is made of a ferromagnetic material with a Curie point temperature. For example, the matrix segment 111 may be a double-layer structure, wherein the material of the outer wall of the heating element 121 is a heat insulating material, and the material of the inner wall of the heating element 121 is a ferromagnetic material with a Curie point temperature. Therefore, the distance between the heating element 121 and the aerosol generating substrate 120 is closer, and the heat loss during heat transfer is less.

In one embodiment, as shown in FIG. 1, when the aerosol generating substrate 120 is accommodated in the heating element 121, the aerosol generating substrate 120 can be in direct contact with the inner surface of the heating element 121, so that the heat generated by the heating element 121 Can be delivered directly to the aerosol-generating substrate 120 . When there is a gap between the aerosol generating substrate 120 and the inner surface of the heating element 121, the heat needs to be transferred from the heating element 121 to the aerosol generating substrate 120 through the air medium, and the aerosol generating substrate 120 is in direct contact with the inner surface of the heating element 121, The heat does not need to be transferred in the air medium, which further reduces the heat loss during the heat transfer process.

In one embodiment, the shape of the heating element 121, the airway section 112 and the filter section 113 can be hollow tubular, and can be cylindrical. In other embodiments, the matrix section 111, the airway section 112 and the filter section The shape of segment 113 can also be other shapes. Further, the shapes of the matrix section 111 , the airway section 112 and the filter section 113 may be the same, and may all be cylindrical.

In one embodiment, the inner and outer diameters of the heating element 121, the airway section 112, and the filter section 113 can be the same, so that the sidewalls of the matrix section 111, the sidewalls of the airway section 112, and the sidewalls of the filter section 113 Butt in turn.

In this embodiment, as shown in FIG. 1 , the arrows in FIG. 1 indicate the flow direction of the airflow. The airtight cavity 111d of the matrix segment 111 may only include the first opening 111b, that is, all ends of the airtight cavity 111d except the first opening 111b are sealed so that the airflow cannot enter the matrix segment 111 .

Specifically, in this embodiment, the air passage section 112 is provided with a first air intake hole 112b, and the number of the first air intake hole 112b is at least one. The first air intake hole 112b connects the outside atmosphere with the suction channel 112a, so that the airflow can enter the suction channel 112a from the first air intake hole 112b, thereby carrying the aerosol generated in the matrix segment 111, and passing through the suction channel 112a enter the inner space of the filter section 113, and flow out from the second opening 113a of the filter section 113, so as to realize the user's suction process.

Wherein, the aerosol matrix structure 100 makes the matrix segment 111 form a closed cavity 111d to accommodate the aerosol generating matrix 120 through the closed cavity 111d, so that when the aerosol generating matrix 120 is accommodated in the heating element 121, the aerosol can be generated. The matrix 120 is in a sealed state to prevent the aerosol-generating matrix 120 in the aerosol matrix structure 100 from falling out into the heating device during or after the suction is completed. At the same time, after the suction is completed, the residue of the aerosol-generating substrate 120 can be taken out together with the aerosol-substrate structure 100, so as to avoid the problem of leaving or adhering to the heating device and facilitate the cleaning of the heating device.

In addition, during the suction process, the airflow does not pass through the aerosol-generating matrix 120 in the matrix section 111, the cracking reaction of the aerosol-generating matrix 120 will not be affected by the cold air, and the cracking reaction is stable, which is beneficial to the generation of aerosol substances. The consistency of the ingredients is conducive to improving the user's smoking taste.

Since the formed aerosol has a displacing effect on the gas in the closed chamber 111d, the oxygen content in the matrix section 111 will decrease as the heating process proceeds. At this time, even if the heating temperature is increased, the aerosol-generating matrix 120 will not Combustion occurs. Therefore, the heating temperature of the aerosol-generating substrate 120 can be further increased to fully release the aroma components in the aerosol-generating substrate 120 and improve the user's puffing taste.

In a specific embodiment, as shown in FIG. 1, the heating element 121 has an annular side wall 111e and a bottom wall 111f. The bottom wall 111f is arranged at the end of the annular side wall 111e away from the air passage section 112, and is connected to the annular side wall 111e. A closed cavity 111d is formed around it. The annular side wall 111e and the bottom wall 111f can seal the end of the heating element 121 away from the airway section 112 through close cooperation, or the annular side wall 111e and the bottom wall 111f can be integrally formed, that is, the heating element 121 is integrally formed, and the airtight cavity 111d is Integral molding makes the end of the matrix segment 111 away from the airway segment 112 airtight. Compared with the tight fit between the annular side wall 111e and the bottom wall 111f, the integral formation of the airtight cavity 111d can make the inside of the matrix segment 111 better sealed, and in the case of handling, moving, unpacking and other external forces, the bottom The wall 111f is also not easy to loosen and fall off, which can prevent the aerosol-generating substrate 120 from falling out and make the heating device difficult to clean, and at the same time prevent the airflow from entering the substrate segment 111, causing the problem of poor consistency of the generated aerosol.

In the first embodiment, as shown in FIG. 1, the materials of the annular side wall 111e and the bottom wall 111f of the matrix segment 111 are both ferromagnetic materials with a Curie point temperature, and the annular side wall 111e and the bottom wall 111f are integral forming. The aerosol matrix structure 100 sucks the aerosol through several first air inlet holes 112b.

The matrix section 111 of the first embodiment is a closed structure, and the airflow does not pass through the matrix section 111. Therefore, the outflow of the aerosol generated in the matrix section 111 is relatively difficult for the open structure at both ends of the matrix section 111, and the airflow cannot carry The amount of aerosol produced or brought out is small, which affects the user's inhalation experience.

In view of the larger number of first air inlet holes 112b, the lower the temperature of the airflow in the aerosol matrix structure 100 and the lower the suction resistance, and the amount of aerosol sucked by the aerosol matrix structure 100 increases with the first air inlet hole. The increase in the number of 112b presents a trend of first increasing and then decreasing. Therefore, the specific number of first air intake holes 112b can be selected and set according to actual conditions. Specifically, the number of first air inlet holes 112b is several, and several first air outlet holes are distributed at intervals along the circumferential direction of the air passage section 112. Preferably, several first air outlet holes are distributed along the circumferential direction of the air passage section 112 The directions are evenly distributed at intervals, so that the air intake in each radial direction of the air passage section 112 is relatively uniform.

Specifically, the shape of the first air inlet 112b can be circular, oval, diamond, square, etc., and the shape of the first air inlet 112b should be selected according to the production process and cost of the aerosol matrix structure 100 .

Specifically, since the larger the diameter of the first air inlet hole 112b is, the lower the temperature of the airflow in the aerosol matrix structure 100 is, the larger the amount of aerosol inhaled by the user is, and the lower the suction resistance is. Therefore, the aperture size of the first air inlet hole 112b can be selected and set according to actual conditions. Of course, considering the support effect of the air passage section 112, the number and aperture size of the first air inlet holes 112b should be designed in combination with the diameter of the air passage section 112, so as to avoid the air passage section 112 being easily damaged due to the large opening area. deformation and collapse, thereby causing a problem of clogging the suction passage 112a. In a specific embodiment, the diameter of the first air inlet hole 112b may be 0.2mm-1mm.

In one embodiment, the linear distance between the first air inlet 112b and the first opening 111b can be 2mm-14mm, so as to shorten the linear distance between the first air inlet 112b and the first opening 111b, so that the aerosol matrix structure The higher the temperature of the airflow within 100, the greater the amount of aerosol that can be inhaled by the user.

In a specific embodiment, the first air inlet 112b may be disposed at an end of the airway segment 112 close to the matrix segment 111 , of course, the first air inlet 112b may also be disposed at other positions of the airway segment 112 . The position of the opening can be designed according to the structure of the aerosol generating device 200 (see Figure 6 below). It should be noted that the design of the opening position should prevent the aerosol generating device 200 from blocking the first air inlet 112b, thus affecting the aerosol Intake of matrix structure 100 .

Preferably, in a specific embodiment, the number of the first air outlet holes is 4-10, the shapes of the first air outlet holes are all circular, and the diameter of the circular first air inlet hole 112b is 0.6mm- 0.8 mm, and the average straight line distance between the plurality of first air inlets 112 b and the first opening 111 b is 4 mm-10 m, and are evenly spaced in the circumferential direction of the air passage section 112 . The design of the first air outlet can make the amount of sucked aerosol relatively sufficient, the suction resistance is moderate, and the temperature of the airflow is moderate, and the user's suction experience is better.

From the above analysis, it can be seen that when the substrate section 111 is of a closed structure, the heating temperature of the aerosol-generating substrate 120 is higher than that of the non-closed structure, and the opening position of the first air inlet 112b is usually farther away from the substrate section 111. Recently, the temperature of the aerosol that causes the user to inhale is usually high, which may bring a bad inhalation experience to the user.

In view of this, in one embodiment, please refer to FIG. 2, which is a cross-sectional view of the aerosol matrix structure 100 provided in the second embodiment. Considering the high temperature of the aerosol inhaled by the user, the airway section While the side wall of 112 is provided with some first air inlets 112b, also be provided with some second air inlets 112c, the second air inlets 112c is by introducing outside cold air in the suction process, to enter the suction channel 112a. The aerosol inside is cooled.

In one embodiment, as shown in FIG. 2 , several first air inlets 112b are arranged at the end of the airway section 112 close to the matrix section 111, and several second airholes 112c are arranged at the end of the airway section 112 away from the matrix section 111. one end. The aperture of the second air inlet 112c is smaller than the aperture of the first air inlet 112b, so that most of the airflow enters through the first air inlet 112b, and drives the aerosol generated by the matrix section 111 to pass through the suction channel 112a and the filter section 113 is for the user to inhale to realize the aerosol inhalation process. A small part of the airflow enters through the second air inlet 112c, because the aperture of the second air inlet 112c is relatively small, and the air flow entering through the second air inlet 112c is less, which will not produce significant dilution on the aerosol. At the same time, the temperature of the aerosol entering the filter section 113 can be appropriately reduced, so that the temperature of the aerosol inhaled by the user is moderate, thereby satisfying the user's inhalation experience.

In one embodiment, several second air inlet holes 112c are arranged at intervals along the circumferential direction of the air passage section 112 . Preferably, the plurality of first air outlet holes and the plurality of second air inlet holes 112c are evenly spaced along the circumferential direction of the air passage section 112, so that the air intake in each radial direction of the air passage section 112 is relatively uniform.

In one embodiment, as shown in FIG. 2 , the airway section 112 includes a plurality of second air inlet hole sets 112d, and the plurality of second air inlet hole sets 112d are located at an end of the airway section 112 away from the matrix section 111 . There are several second air intake holes 112c in each second air intake hole set 112d. A plurality of second air intake hole sets 112d are arranged at intervals along the axial direction of the air channel segment 112, and several second air intake holes 112c in each second air intake hole set 112d are arranged at intervals along the circumferential direction of the air channel segment 112 . By providing a plurality of second air intake hole sets 112d, the temperature of the airflow in the air passage section 112 can be lowered to a greater extent, and the user's suction experience can be improved.

In the second embodiment, as shown in FIG. 2, several first air inlet holes 112b and two second air inlet hole sets 112d are provided on the side wall of the air passage section 112, and the two second air inlet hole sets 112d Each includes a number of second air inlets 112c. A number of first air inlet holes 112b are uniformly arranged on the side of the air passage section 112 close to the matrix section 111, and two sets of second air inlet holes 112d are arranged on the side of the air passage section 112 near the filter section 113, each Several second air inlet holes 112c in the second air inlet hole sets 112d are evenly spaced along the circumferential direction of the air passage section 112 .

In one embodiment, please refer to FIG. 3 and FIG. 4 , FIG. 3 is a cross-sectional view of a third embodiment of the aerosol matrix structure 100 . FIG. 4 is a cross-sectional view of a fourth embodiment of an aerosol matrix structure 100 . The airway section 112 may also be provided with a cooling medium 112e for cooling the aerosol entering the airway section 112 to improve the user's suction experience.
