The entire disclosure of both applications is hereby incorporated by reference herein.

FIELD

This application relates to the technical field of electronic atomization apparatuses, and particularly relates to an aerosol generation article and an aerosol generation apparatus.

BACKGROUND

A heat-not-burning (Heat Not Burning, HNB) apparatus is a combination device of a heating apparatus and an aerosol generation substrate (a processed plant leaf product). The heating apparatus is heated to a high temperature at which the aerosol generation substrate can generates aerosols without burning. In this way, the aerosol generation substrate can generate aerosols required for users without burning.

While aerosols are generated through atomization by an existing heat-not-burning apparatus, airflow does not flow through the aerosol generation substrate, leading to a poor effect in taking the aerosols generated by the aerosol generation substrate to an inhaling opening and accordingly resulting in less aerosols at the inhaling opening of the heat-not-burning apparatus.

The following describes this application in detail with reference to the accompanying drawings and embodiments.

Referring to FIG. 1. FIG. 1 is a cross-sectional view of an aerosol generation article provided in this application. In this embodiment, the aerosol generation article 100 (as shown in FIG. 16) includes a substrate section 111, an airway section 112 and a filter section 113 connected in sequence and in air communication. In this application, the substrate section 111, the airway section 112 and the filter section 113 each refer to a housing for a corresponding functional section of the aerosol generation article 100, and are each further provided with other elements therein.

Specifically, the substrate section 111 has a cavity 111d inside, and the cavity 111d is configured to store an aerosol generation substrate 120, for example, leaves or flowers of plants. In an embodiment, the substrate section 111 may be a tubular element enclosed by an annular side wall, for example, a circular pipe of which one end is closed and the other end is open, so that a cavity 111d is formed therein. An aerosol generation substrate 120 is arranged in the cavity 111d. The open end of the substrate section 111 is a first opening 111b, and the first opening 111b is in communication with the airway section 112.

In this embodiment, the substrate section 111 can further serve as a heating element for generating heat through electromagnetic induction, so as to heat the aerosol generation substrate 120 therein. The side wall of the substrate section 111 may be made of a metal material, or a metal material layer is arranged on the inner surface or outer surface of the side wall of the substrate section 111. In this embodiment, the aerosol generation substrate 120 may be in direct contact with the inner surface of the substrate section 111, so that the heat generated by the substrate section 111 can be directly transferred to the aerosol generation substrate 120, and the heat does not need to be transferred in an air medium, so heat loss in a heat transfer process can be reduced.

In an embodiment, in order to allow the side wall of the substrate section 111 to generate heat through electromagnetic induction, the material of the substrate section 111 is a ferromagnetic material with a Curie point temperature. Below the Curie point temperature, the ferromagnetic material is ferromagnetic and can continuously generate heat through electromagnetic induction under the action of an oscillating coil, thereby heating and baking the aerosol generation substrate 120. Above the Curie point temperature, the ferromagnetic material is transformed from ferromagnetic to paramagnetic, to be specific, the side wall of the substrate section 111 at this moment is no longer magnetic and stops heating the aerosol generation substrate 120 through electromagnetic induction, so that the temperature of the aerosol generation substrate 120 is accurately controlled within a certain temperature range, thereby preventing a problem such as scorching of the aerosol generation substrate 120 caused by an excessively high temperature for heating the aerosol generation substrate 120. In this way, the temperature of the aerosol generation substrate 120 can be accurately controlled.

An air inlet hole 142 is arranged on the side wall of the airway section 112, and the air inlet hole 142 and the substrate section 111 are arranged at an interval. To be specific, the air inlet hole 142 is arranged on one side of the middle of the airway section 112 close to the substrate section 111, and has a certain distance from the substrate section 111. When the aerosol generation substrate 120 is heated by the side wall of the substrate section 111, the temperature of airflow close to the substrate section 111 rises, which results in a temperature rise of aerosol formed by the aerosol generation substrate 120. The air inlet hole 142 is arranged at one end of the middle of the airway section 112 close to the substrate section 111 and has a certain distance from the substrate section, which ensures that when the aerosol generation substrate 120 is heated by the side wall of the substrate section 111, the influence of the side wall of the substrate section 111 on the temperature of the airflow in the airway section 112 can be reduced to some extent, so that the temperature of the airflow is not too high, thereby improving the user experience during inhaling.

In addition, in this embodiment, the airflow entering the airway section 112 through the air inlet hole 142 flows through only the first opening 111b of the cavity 111d without entering the cavity 111d. A plurality of air inlet holes 142 may be provided, and the plurality of air inlet holes 142 are arranged along the circumference of the side wall of the airway section 112. Such design can achieve a sufficient amount of inhaled aerosol, an appropriate inhaling resistance and an appropriate airflow temperature to some extent, thereby providing a good inhaling experience for users. The air inlet hole 142 may be circular, elliptic, rhombus, square, or the like in shape, which is selected based on production processes and costs of the aerosol generation article 100 and is not limited herein.

Still referring to FIG. 2, an airflow guiding element 122 is arranged in the airway section 112; a first inhaling channel 122d is arranged in the airflow guiding element 122; the first inhaling channel 122d is in communication with the cavity 111d; an airflow guiding channel 132 is formed between the side wall of the airflow guiding element 122 and the inner side surface of the airway section 112; the airflow guiding channel 132 is in communication with the cavity 111d; and the airflow guiding channel 132 is configured to guide the airflow entering the air inlet hole 142 to one end of the cavity 111d close to the airflow guiding element 122, so as to take away the aerosols at the first opening 111b.

Specifically, during inhaling, the aerosol formed by the aerosol generation substrate 120 diffuses to the first opening 111b, the external airflow enters the airflow guiding channel 132 through the air inlet hole 142, the airflow guiding channel 132 guides the airflow to the first opening 111b of the cavity 111d, and the airflow takes the aerosols, then flows into the first inhaling channel 122d and is ultimately inhaled by a user via the filter section 113. In this process, the airflow guiding 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, enhancing airflow disturbance at the first opening 111b, thereby allowing more aerosols to diffuse to the first opening 111b. In this way, more aerosols are taken to the filter section 113, increasing the amount of aerosol inhaled by the user at a time, thereby improving the user experience.

Still referring to FIG. 3, airflow guiding element 122 includes a seal portion 122a, an airflow guiding portion 122b and a communication portion 122c. The first inhaling channel 122d penetrates through the seal portion 122a, the airflow guiding portion 122b and the communication portion 122c. Specifically, the seal portion 122a is arranged close to the filter section 113, and the communication portion 122c of the airflow guiding element 122 is arranged close to the substrate section 111. The outer side surface of the seal portion 122a abuts against the inner side surface of the airway section 112 to prevent the airflow from directly diffusing to the filter section 113. The airflow guiding channel 132 is formed between the side walls of the airflow guiding portion 122b and the communication portion 122c and the inner side surface of the airway section 112, and the airflow guiding channel 132 changes the direction of the airflow entering the air inlet hole 142, so that all the airflow flows through the first opening 111b of the cavity 111d first and then enters the first inhaling channel 122d. In order to allow the airflow guiding portion 122b to conveniently change the direction of the airflow entering the air inlet hole 142 to make the airflow flow through the first opening 111b along the airflow guiding channel 132, the airflow guiding portion 122b is arranged corresponding to the air inlet hole 142.

Still referring to FIG. 4 and FIG. 5, in this embodiment, the outer diameter of the airflow guiding portion 122b and the outer diameter of the communication portion 122c are both smaller than the outer diameter of the seal portion 122a, and the outer diameter of the airflow guiding portion 122b is larger than the outer diameter of the communication portion 122c. By such design, a space exists between the entire outer side surfaces of the airflow guiding portion 122b and the communication portion 122c and the entire inner side surface of the airway section 112, so as to form the airflow guiding channel 132. In other embodiments, as shown in FIG. 16, the outer diameter of the airflow guiding portion 122b and the outer diameter of the communication portion 122c may also be equal to the outer diameter of the seal portion 122a; one or more grooves are arranged on the outer surface of the airflow guiding portion 122b and the outer surface of the communication portion 122c along the axial direction of the airflow guiding element 122; and the one or more grooves match with the inner side surface of the airway section 112 to form the airflow guiding channel 132. The outer diameter of the seal portion 122a corresponds to the inner diameter of the airway section 112.

In an embodiment, referring to FIG. 3 to FIG. 6, the outer diameter of the airflow guiding portion 122b is consistent along a direction from the filter section 113 to the substrate section 111, to be specific, the airflow guiding portion 122b is cylindrical. In an embodiment, referring to FIG. 7, the outer diameter of the airflow guiding portion 122b gradually increases along the direction from the filter section 113 to the substrate section 111, to be specific, the airflow guiding portion 122b is in a conical frustum shape. In another embodiment, the outer diameter of the airflow guiding portion 122b may also gradually decrease along the direction from the filter section 113 to the substrate section 111. Further, the joint between the airflow guiding portion 122b and the seal portion 122a may be in gradual transition connection by virtue of a buffer section A or is connected through a vertical plane (as shown in FIG. 10). Specifically, referring to FIG. 3 to FIG. 7, the outer diameter of the joint between the airflow guiding portion 122b and the seal portion 122a gradually decreases along the direction from the filter section 113 to the substrate section 111 to form a buffer section. It can be understood as that the outer side surface of the joint between the airflow guiding portion 122b and the seal portion 122a is a tapered surface, for example, as shown in FIG. 3 to FIG. 5. Alternatively, the outer side surface of the joint between the airflow guiding portion 122b and the seal portion 122a is an indented arc-shaped surface, for example, as shown in FIG. 6 and FIG. 7. It can also be understood as that the buffer section A can also practically serve as the airflow guiding portion 122b or serve as a part of the airflow guiding portion 122b, for example, as shown in FIG. 8 and FIG. 9. The design of the buffer section A can reduce obstruction of the side wall of the airflow guiding portion 122b to the airflow.

The communication portion 122c is in communication with the first opening 111b of the cavity 111d. In an embodiment, referring to FIG. 8, the communication portion 122c includes a plurality of support bars, and the plurality of support bars are arranged at intervals along the circumference of the airflow guiding portion 122b, so that the airflow guiding channel 132 is in communication with the cavity 111d. In another embodiment, referring to FIG. 9, the communication portion 122c includes a communication pipe, and a plurality of vent holes is arranged on the side wall of the communication pipe, so that the airflow guiding channel 132 is in communication with the cavity 111d.

In other embodiments, the communication portion 122c is a part of the airflow guiding portion 122b, to be specific, the airflow guiding element 122 includes the seal portion 122a and the airflow guiding portion 122b arranged coaxially; the airflow guiding portion 122b is in direct communication with the first opening 111b of the cavity 111d; and the communication portion 122c is an optional structure.

The first inhaling channel 122d penetrates through the seal portion 122a, the airflow guiding portion 122b and the communication portion 122c. The cross section of the first inhaling channel may be in various shapes. For example, the cross section is in a circular shape (as shown in FIG. 11), an elliptic shape (as shown in FIG. 12), a cross shape (as shown in FIG. 13), a pentacle shape (as shown in FIG. 14), or a combination of a circular shape and a cross shape (as shown in FIG. 15).

In addition, in order to facilitate installation of the airflow guiding element 122 in the airway section 112 and facilitate production and manufacturing of the airflow guiding element 122, in an embodiment, the airflow guiding element 122 is integrally formed, to be specific, the seal portion 122a, the airflow guiding portion 122b and the communication portion 122c are integrally formed. The materials of the airflow guiding element 122 may be materials such as carboxylate fibers, ceramics, and high temperature resisting organic materials.

Still referring to FIG. 1 and FIG. 2, a first support element 152 is further arranged in the airway section 112; the first support element 152 is arranged between the filter section 113 and the airflow guiding element 122 and abuts against the airflow guiding element 122; and the first support element 152 includes a second inhaling channel 152a to achieve communication between the first inhaling channel 122d and the filter section 113.

Further, the airflow guiding element 122 has a protrusion or a groove on the end face close to the first support element 152 for being snap-fitted with the first support element 152. Specifically, in another embodiment, as shown in FIG. 4, the airflow guiding element 122 has a protrusion on the seal portion 122a, the first support element 152 has a groove on the end face, and the first support element 152 is snap-fitted with the airflow guiding element 122. In an embodiment, as shown in FIG. 5, a groove is arranged on the seal portion 122a of the airflow guiding element 122, the first support element 152 has a protrusion on the end face, and the first support element 152 is snap-fitted with the airflow guiding element 122. In an embodiment, as shown in FIG. 6, the seal portion 122a of the airflow guiding element 122 is horizontal, the end face of the first support element 152 is horizontal, and the first support element 152 abuts against the airflow guiding element 122.

As shown in FIG. 1, further, a second support element 162 is further arranged in the airway section 112; the second support element 162 is arranged between the substrate section 111 and the airflow guiding element 122 and abuts against the airflow guiding element 122; and the second support element 162 is provided with a third inhaling channel 162a to achieve communication between the first inhaling channel 122d and the cavity 111d. Specifically, in an embodiment, as shown in FIG. 8, the communication portion 122c of the airflow guiding element 122 is a support bar, and the second support element 162 abuts against the support bar. In an embodiment, as shown in FIG. 9, the communication portion 122c of the airflow guiding element 122 is a communication pipe, and the second support element 162 abuts against the communication pipe. In addition, in order to facilitate installation, in another embodiment, the second support element 162 and the airflow guiding element 122 may be integrally formed. Moreover, in this embodiment, the material of the first support element 152 and the second support element 162 may be cellulose acetate fibers; and the cellulose acetate fibers are used not only as a support element for fixing the airflow guiding element 122 but also as a cooling medium for cooling the airflow flowing through the second inhaling channel 152a and the third inhaling channel 162a.

The filter section 113 is in communication with one end of an inhaling channel 112a of the airway section 112 facing away from the substrate section 111, so that aerosols in the inhaling channel 112a can enter the filter section 113, and thus the aerosols inhaled in the airway section 112 are filtered through the filter section 113. Specifically, the filter section 113 may be arranged on one side of the airway section 112 away from the substrate section 111, and the filter section 113 may be filled with a filter medium. The filter medium can filter tar, suspended particles or the like in the aerosols, so that the filter medium filters the aerosols inhaled in the airway section 112, thereby reducing unwanted substances in the aerosols inhaled by users. The material of the filter medium may be cellulose acetate fibers.

Further, a second opening 113a is arranged at one end of the filter section 113 facing away from the airway section 112, so that the internal space of the filter section 113 is in communication with the external atmosphere. In an inhaling process, the airflow guiding channel 132 changes the direction of the airflow entering the airway section 112, so that the airflow rushes to the first opening 111b of the cavity 111d, enhancing airflow disturbance at the first opening 111b, thereby allowing more aerosols to diffuse to the first opening 111b. In this way, more aerosols are taken to the second opening 113a, and the users can inhale the aerosols from the second opening 113a.

In an embodiment, the substrate section 111, the airway section 112 and the filter section 113 may be in a hollow pipe shape and may be cylindrical. In other embodiments, the substrate section 111, the airway section 112 and the filter section 113 may also be in other shapes, for example, in an elliptic shape. In an embodiment, the heating element 121, the airway section 112 and the filter section 113 may have the same outer diameter, so that the side wall of the substrate section 111, the side wall of the airway section 112 and the side wall of the filter section 113 abut against each other in sequence. In addition, the material of the airway section 112 and the filter section 113 may be a paper-based or foil-based material.

The material of the substrate section 111 may be a ferromagnetic material with a Curie point temperature. The ferromagnetic material may be an iron-nickel alloy, so that the ferromagnetic material can generate heat through electromagnetic induction, so as to heat and atomize the aerosol generation substrate 120 to generate aerosols.

In this embodiment, the airflow guiding channel 132 is formed between the side wall of the airflow guiding element 122 and the inner side surface of the airway section 112. The airflow guiding channel 132 is in communication with the first opening 111b of the cavity 111d. The airflow does not flow through the aerosol generation substrate 120 in the substrate section 111, and the aerosol formed by the aerosol generation substrate 120 in the airway section 112 diffuses to the first opening 111b. When the external airflow enters the airflow guiding channel 132 through the air inlet hole 142, the airflow guiding channel 132 changes the direction of the airflow, so that the airflow rushes to the first opening 111b of the cavity 111d, enhancing airflow disturbance at the first opening 111b, thereby allowing more aerosols to diffuse to the first opening 111b. In this way, more aerosols are taken to the second opening 113a, increasing the amount of aerosol inhaled by the user at a time, thereby improving the user experience.

This application further provides an aerosol generation apparatus 200. Referring to FIG. 17, FIG. 17 is a schematic structural diagram of an aerosol generation apparatus 200 provided in this application. The aerosol generation apparatus 200 is configured to heat and bake an aerosol generation article 100 to generate aerosols for users to inhale.

The aerosol generation apparatus 200 includes a heating apparatus 210 and the aerosol generation article 100.

The heating apparatus 210 includes a power supply assembly 211 and a heating assembly 212, and the power supply assembly 211 is connected to the heating assembly 212 to supply power to the heating assembly 212. After powered on, the heating assembly 212 can heat the aerosol generation substrate 120 in the aerosol generation article 100 to generate aerosols.

For the aerosol generation article 100 in the aerosol generation apparatus 200, reference may also be made to the structure and functions of the aerosol generation article 100 of any one of the above embodiments, and same or similar technical effects can be achieved. Details are not described herein again.

The power supply assembly 211 includes a battery and a controller. The controller is electrically connected to the battery and the heating assembly 212. The battery is configured to provide power supply for the heating assembly 212 to heat the aerosol generation article 100. The controller is configured to control start and stop of heating of the heating assembly 212 and can control parameters such as power and temperature of the heating.

In an embodiment, as shown in FIG. 6, the material of the substrate section 111 of the aerosol generation article 100 in the aerosol generation apparatus 200 includes a ferromagnetic material with a Curie point temperature. The heating assembly 212 is an electromagnetic coil 212a, and the power supply assembly 211 is connected to the electromagnetic coil 212a to supply power to the electromagnetic coil 212a. The electromagnetic coil 212a is configured to generate a magnetic field after powered on, so that the side wall of the substrate section 111 in the aerosol generation article 100 heats and atomizes the aerosol generation substrate 120 through electromagnetic induction to generate aerosols.

In addition, the material of the substrate section 111 is a ferromagnetic material with a curie point temperature. Therefore, below the Curie point temperature, the ferromagnetic material is ferromagnetic and can continuously generate heat through electromagnetic induction under the action of an oscillating coil, thereby heating and baking the aerosol generation substrate 120. However, above the Curie point temperature, the ferromagnetic material is transformed from ferromagnetic to paramagnetic, to be specific, the side wall of the substrate section 111 at this moment is no longer magnetic and stops heating the aerosol generation substrate 120 through electromagnetic induction, so that the temperature of the aerosol generation substrate 120 can be accurately controlled within a certain temperature range, thereby preventing a problem such as scorching of the aerosol generation substrate 120 caused by an excessively high temperature for heating the aerosol generation substrate 120. As a result, the temperature of the aerosol generation substrate 120 is accurately controlled, so that it is unnecessary to additionally provide a temperature sensing assembly in the heating apparatus, thereby effectively lowering the production cost.

In this embodiment, the substrate section 111 of the aerosol generation article 100 in the aerosol generation apparatus 200 has a cavity 111d, and the cavity 111d is configured to store the aerosol generation substrate 120. In a state that the aerosol generation substrate 120 is stored in the cavity 111d, the aerosol generation substrate 120 can be in direct contact with the inner surface of the cavity 111d.

As the cavity 111d is arranged in the substrate section 111 of the aerosol generation article 100 in the aerosol generation apparatus 200, the aerosol generation substrate 120 stored in the cavity 111d is in a sealed state, so that during use of the aerosol generation article 100, the aerosol generation substrate 120 does not fall into the heating apparatus 210 from the aerosol generation article 100. After inhaling is completed, residues of the aerosol generation substrate 120 can be taken out together with the aerosol generation article 100 without being left in or attached to the heating apparatus 210, facilitating cleaning of the heating apparatus 210. In addition, in an embodiment, the airflow guiding element 122 and the aerosol generation article 100 are integrally formed. After the aerosol generation substrate 120 is inhaled completely, the airflow guiding element 122 can be replaced together with the aerosol generation article 100 without cleaning the airflow guiding element 122 and the aerosol generation article 100. In this way, more convenient cleaning of the heating apparatus 210 is realized.

Besides, during inhaling, the airflow does not flow through the aerosol generation substrate 120 in the substrate section 111; the airflow guiding channel 132 is formed between the side wall of the airflow guiding element 122 in the airway section 112 and the inner surface of the airway section 112; the airflow guiding channel 132 is in communication with the first opening 111b; the aerosol formed by the aerosol generation substrate 120 diffuses to the first opening 111b; the external airflow enters the airflow guiding channel 132 through the air inlet hole 142; and the airflow guiding channel 132 changes the direction of the airflow, so that the airflow rushes to the first opening 111b of the cavity 111d, and airflow disturbance at the first opening 111b is enhanced. As a result, more aerosols diffusing to the first opening 111b are taken away, increasing the amount of aerosol inhaled by the user at a time, thereby improving the user experience (on the premise of ensuring the temperature).
