Description
TECHNICAL FIELD

[0002] An aerosol generation device is a device that heats and atomizes an aerosol substrate to generate an aerosol. Generally, the aerosol substrate has a substrate section, a cooling section, and a filter section. When the aerosol substrate is inserted into the aerosol generation device, a user can draw the filter section, and the airflow enters from the bottom surface of the substrate section and carries the aerosol generated by the substrate section to the cooling section and then to the filter section for the user to draw. Alternatively, the airflow can enter from the air inlet hole of the cooling section to form a negative pressure at the top of the substrate section, and the aerosol generated by the substrate section can flow to the cooling section under the action of the negative pressure and then to the filter section for the user to draw.
[0003] However, in the case of air inlet from the bottom surface of the substrate section, the airflow flows too fast, resulting in a large amount of aerosol in the first few puffs and a small amount of aerosol in the subsequent puffs, which reduces the continuity of the puffs. In addition, air inlet from the bottom surface of the substrate section can cause the airflow to carry more water molecules, resulting in a higher temperature of the aerosol. In the case of air inlet from the cooling section, the aerosol is carried out under the action of the negative pressure, and the speed of the aerosol outflow is slower. CONTENT OF THE INVENTION

[0027] Please refer to Figures 1-4The present application provides an aerosol generating system. The aerosol generating system comprises an aerosol substrate 10 and an aerosol generating device 20. The aerosol substrate 10 is used as a consumable and is matched with the aerosol generating device 20. The aerosol substrate 10 is a solid aerosol substrate 10 and is substantially in the shape of a cylinder. Specifically, the aerosol substrate 10 comprises a substrate section 11, and the substrate section 11 is used for heating to generate aerosol. In an embodiment, the substrate section 11 comprises a wrapping member and a substrate material, the wrapping member is circumferentially wrapped around the substrate material, and the wrapping member forms a side wall of the substrate section 11. The substrate material may, for example, be a tobacco leaf type substrate, and the wrapping member may, for example, be paper. In addition, in some embodiments, the aerosol substrate 10 can further comprise a plurality of functional sections to achieve different functions, and the wrapping member of the substrate section 11 can also serve as a side wall of other functional sections, i.e., the wrapping member can serve as an outer side wall of the entire aerosol substrate 10.
[0028] The aerosol generating device 20 is provided with a mounting cavity 21, one end of the mounting cavity 21 is provided with an opening 211, the opening 211 is used for inserting the aerosol substrate 10 into the mounting cavity 21, and the other end of the mounting cavity 21 is in a closed structure. As shown in Figure 3 Figure 3 The arrow indicates the flow direction of the airflow when the user is smoking. When the aerosol substrate 10 is inserted into the mounting cavity 21, an air inlet channel 30 is formed between the side wall of the aerosol substrate 10 and the side wall of the mounting cavity 21, i.e., the outer side wall of the wrapping member and the inner side wall of the mounting cavity 21 form the air inlet channel 30. Preferably, the air inlet direction of the air inlet channel 30 is substantially parallel to the axis direction of the aerosol substrate 10.
[0029] In an embodiment, the aerosol generating device 20 comprises a heating member 22, and the heating member 22 can heat the substrate section 11 of the aerosol substrate 10. The heating mode of the heating member 22 is at least one of central heating, circumferential heating, electromagnetic induction heating, infrared heating, microwave heating, and resistance heating. The central heating refers to that a heating needle is arranged at the bottom of the mounting cavity 21, and when the aerosol substrate 10 is inserted into the mounting cavity 21, the heating needle is inserted into the aerosol substrate 10 from the bottom of the aerosol substrate 10 along the central axis of the aerosol substrate 10. The circumferential heating refers to that the heating member 22 is tubular, and when the aerosol substrate 10 is inserted into the mounting cavity 21, the heating member 22 is arranged around the peripheral side of the substrate section 11 to heat the substrate section 11 in the circumferential direction. When the heating member 22 is in the circumferential heating, as shown in Figure 3 As shown, the heating member 22 can be used to form the installation cavity 21, so that the installation cavity 21 has a heating cavity. The electromagnetic induction heating generally provides a coil in the aerosol generating device 20, and the coil generates a magnetic field by being energized. The heating body made of ferromagnetic material or metal material can be arranged around or inside the aerosol substrate 10, and the heating body can generate heat to heat the aerosol substrate 10 under the action of the magnetic field. The infrared heating and microwave heating are respectively used to heat the aerosol substrate 10 by infrared and microwave. The resistance heating is to make the resistance heat by being energized, and the resistance is in heat conduction contact with the aerosol substrate 10 to heat the aerosol substrate 10.
[0030] The side wall of the substrate section 11 is provided with an air hole 111, that is, at least the wrapping member of the substrate section 11 is provided with the air hole 111, so that the air inlet channel 30 can communicate with the inside of the substrate section 11 through the air hole 111. The axis of the air hole 111 is at an angle with the axis of the aerosol substrate 10, and the air hole 111 extends from the outside of the substrate section 11 to the inside of the substrate section 11. Preferably, the axis of the air hole 111 is arranged along the radial direction of the substrate section 11.
[0031] The substrate section 11 has a first end 112 and a second end 113 arranged opposite along the axial direction of the substrate section 11, and the second end 113 is arranged closer to the opening 211 than the first end 112. Here, the first end 112 and the second end 113 refer to the two end faces of the substrate section 11 farthest along the axial direction. The ratio of the axial distance between the air hole 111 and the first end 112 to the total axial length of the substrate section 11 is less than or equal to 1 / 2, for example, less than or equal to 1 / 2, 1 / 3, 1 / 4, 1 / 5, etc., that is, the air hole 111 is arranged closer to the first end 112 than the second end 113. Among them, the ratio of the maximum axial distance between the air hole 111 and the first end 112 to the total axial length of the substrate section 11 is less than or equal to 1 / 2, and the maximum axial distance is the maximum distance between the air hole 111 and the first end 112 along the axial direction.
[0032] Because the aerosol substrate 10 of the present application is provided with the air hole 111 in the side wall of the substrate section 11, when the user inhales, the airflow will enter from the side wall of the substrate section 11, pass through the substrate material at the top of the air hole 111 and carry out the aerosol, and when the substrate material at the top of the air hole 111 is inhaled and permeated, the negative pressure is generated due to the fast flow rate at the top of the air hole 111, and the aerosol formed by the substrate material at the bottom of the air hole 111 can be carried out under the action of the negative pressure.
[0033] The existing substrate section bottom surface air inlet mode, the airflow flows through the entire substrate section, so the first few puffs before suction will bring out the aerosol of the entire substrate section, resulting in insufficient aerosol continuity in the later stage of suction. The airflow flow mode of the aerosol substrate 10 of the present application, when suction, first through the airflow flow in the top of the air hole 111 of the substrate material in the front section to bring out the aerosol generated, when the substrate material in the top of the air hole 111 is suctioned and permeated, the aerosol generated by the substrate material in the bottom of the air hole 111 will be brought out, that is, the substrate material in the top of the air hole 111 and the substrate material in the bottom of the air hole 111 can be brought out in different periods, the amount of aerosol sucked in the entire period is relatively uniform, increasing the continuity of suction. And compared with the substrate section bottom surface air inlet mode, the distance of the substrate section 11 through by the airflow is relatively reduced, so that the water molecules carried by the airflow can be relatively reduced during the suction process, thereby reducing the temperature of the suctioned aerosol. And the air hole 111 is arranged at a position relatively close to the bottom of the substrate section 11, so that most of the aerosol is brought out by airflow flow, and a small part of the aerosol is brought out by negative pressure, so that compared with the existing cooling section air inlet mode, the speed of bringing out the aerosol can be improved.
[0034] In an embodiment, the substrate section 11 can only be wrapped with the air hole 111 on the upper part, that is, the air hole 111 is not opened on the substrate material, and the airflow enters the substrate material and naturally flows through the pores inside the substrate material. Or, preferably, the air hole 111 can be opened on the wrapping part and the substrate material. Since the airflow enters the substrate section 11 from the side wall of the substrate section 11 in the radial direction, due to the resistance of the substrate material, the airflow closer to the central axis of the substrate section 11 will be smaller, so when the air hole 111 is opened on the substrate material, the resistance of the airflow passing through the substrate material in the radial direction can be reduced, so that the air outlet amount of the substrate section 11 in the radial direction is uniform. Preferably, the air hole 111 penetrates the wrapping part and the substrate material, so that the air outlet amount of the substrate section 11 in the radial direction is more uniform.
[0035] In an embodiment, the number of air holes 111 is multiple, and the multiple air holes 111 are uniformly arranged along the circumference of the substrate section 11. The more the number of circumferentially arranged air holes 111, the more uniform the air outlet amount of the substrate section 11 in the circumferential direction, preferably, the multiple air holes 111 all penetrate the substrate section 11 in the radial direction, and each air hole 111 penetrates the central axis of the substrate section 11.
[0036] In an embodiment, the aerosol substrate 10 further comprises a blocking section 12, a supporting section 13, a temperature reducing section 14 and a filtering section 15, which are sequentially connected, wherein the blocking section 12 is located at the bottom of the mounting cavity 21 away from the opening 211, the blocking section 12 is used to prevent residues in the substrate section 11 from falling into the mounting cavity 21 from the bottom of the aerosol substrate 10, and cellulose acetate can be arranged in the blocking section 12 for blocking. The supporting section 13 and the temperature reducing section 14 are provided with airflow passages. The temperature reducing section 14 can be provided with a temperature reducing hole to reduce the temperature of the outgoing aerosol and avoid burning the mouth. The filtering section 15 can be provided with filtering materials to filter the aerosol.
[0037] In an embodiment, the end face of the blocking section 12 away from the substrate section 11 abuts against the bottom wall of the mounting cavity 21 away from the opening 211, so that the airflow can be prevented from entering the inside of the substrate section 11 from the bottom surface of the aerosol substrate 10, and the airflow can only enter the substrate section 11 from the air holes 111 on the side wall of the substrate section 11, so as to solve a series of problems caused by the airflow entering from the bottom surface of the aerosol substrate 10.
[0038] In an embodiment, the air inlet passage 30 has an air inlet end 31 and an air outlet end 32, the air inlet end 31 is arranged close to the opening 211, and the air outlet end 32 is in communication with the air holes 111, that is, in this embodiment, the airflow enters from the top of the aerosol generating device 20, compared with the airflow entering from the bottom of the aerosol generating device 20, the airflow entering from the top does not need to be guided by the air channel member, which saves the number of parts of the aerosol generating device 20, and the airflow flowing through the outside of the aerosol substrate 10 can also be preheated, which improves the energy utilization efficiency of heat.
[0039] In an embodiment, the cavity wall of the mounting cavity 21 comprises a ring-shaped side wall and a bottom wall, one end of the ring-shaped side wall forms the opening 211, the bottom wall of the mounting cavity 21 is sealingly connected to the end of the ring-shaped side wall away from the opening 211, and the ring-shaped side wall of the mounting cavity 21 and the bottom wall of the mounting cavity 21 are both closed structures. By arranging the ring-shaped side wall of the mounting cavity 21 and the bottom wall of the mounting cavity 21 as closed structures, it can be ensured that there is no air leakage and no liquid leakage in the mounting cavity 21, and the electronic components can be prevented from being damaged by liquid leakage.
[0040] Specifically, the aerosol-generating device 20 can include a housing 23, a bracket assembly 24 disposed inside the housing 23, a first seal 26 and a second seal 27 disposed outside the bracket assembly 24, and a clamping member 25 disposed on a side of the first seal 26 away from the bracket assembly 24. A heating member 22, preferably a heating tube, is fitted inside the bracket assembly 24. The housing 23, the first seal 26, the bracket assembly 24, the heating tube, and the clamping member 25 cooperate to form a mounting cavity 21, and the clamping member 25 and the housing 23 surround an opening 211 of the mounting cavity 21.
