Referring to FIG. 1 and FIG. 2, the utility model provides an aerosol-generating device 100, including a housing 1, a first heating member 2, a second heating member 3, a first energy storage member 4, and an air inlet member 6. The housing 1 provides a mounting space for other components. The first heating member 2 and the second heating member 3 are located in the housing 1, and the first heating member 2 and the second heating member 3 are configured to heat a liquid substrate, to generate an aerosol. The first energy storage member 4 is arranged in the housing 1, and the first energy storage member 4 is configured to provide electric energy for the first heating member 2 and the second heating member 3. The air inlet member 6 is arranged in the housing 1, and the air inlet member 6 is configured to provide external air to enter the interior of an atomization cavity 113 and guide the air to flow through the first heating member 2 and the second heating member 3, to carry the aerosol.

For ease of description, an X axis in each accompanying drawing represents a width direction of the aerosol-generating device 100, a Y axis in each accompanying drawing represents a thickness direction of the aerosol-generating device 100, and a Z axis in each accompanying drawing represents a length direction of the aerosol-generating device 100. Generally, a dimension of the aerosol-generating device 100 in the length direction thereof is larger than a dimension in the width direction, and the dimension in the width direction is larger than a dimension in the thickness direction.

Referring to FIG. 2, a part of the housing 1 is configured as a liquid storage portion 11, where a liquid storage cavity 111, a main airway 112, and at least a part of the atomization cavity 113 are defined in the interior of the liquid storage portion 11. The liquid storage cavity 111 is configured to store a liquid substrate, and the liquid substrate includes, but is not limited to, e-liquid. In the length direction, the atomization cavity 113 is located below the liquid storage cavity 111, and the atomization cavity 113 provides a space to release the aerosol generated by atomizing the liquid substrate by the first heating member 2 and the second heating member 3. The main airway 112 substantially extends in the length direction, one end of the main airway 112 is in communication with the atomization cavity 113, and the other end of the main airway 112 is in communication with the outside. The main airway 112 penetrates the liquid storage cavity 111, that is, the main airway 112 is surrounded by the liquid storage cavity 111. It may be understood that, the liquid storage cavity 111 is in a cylindrical shape, and a hollow part of the liquid storage cavity 111 is the main airway 112. Arranged in the width direction, the main airway 112 is located between the first heating member 2 and the second heating member 3, and the aerosol generated by heating the liquid substrate by the first heating member 2 and the second heating member 3 enters the main airway 112 from the atomization cavity 113, so that a user inhales the generated aerosol through the other end of the main airway 112. That the main airway 112 is located between the first heating member 2 and the second heating member 3 can reduce a length of the airway, and the main airway 112 basically has no corner and step, so that generation of condensate can be reduced, a probability of hole blockage can be reduced, and taste of the user can be improved.

It may be understood that, the liquid storage portion 11 is an integrally formed structure, that is, the liquid storage portion 11 is also formed when the housing is integrally formed, thereby further forming the liquid storage cavity 111, the main airway 112, and the at least part of the atomization cavity 113. According to a non-integrally formed liquid storage portion 11, the non-integrally formed liquid storage portion 11 needs to communicate the atomization cavity 113 with the main airway 112 through a pipeline, increasing the length of the airway. As a result, the condensate may appear in the airway. According to the integrally formed liquid storage portion 11 in this application, the generation of the condensate can be reduced, the probability of hole blockage can be reduced, and the taste of the user can be improved. In addition, the integrally formed liquid storage portion 11 does not need to be sealed by using a sealing member, so that production costs can be reduced.

In some embodiments, the housing 1 and the liquid storage portion 11 are two independent components, and the housing 1 and the liquid storage portion 11 are connected together through assembly. Under this condition, the liquid storage portion 11 may still use the integrally formed structure.

The first heating member 2 is arranged corresponding to the liquid storage cavity 111, and one end of the first heating member 2 is in communication with the liquid storage cavity 111, to absorb the liquid substrate in the liquid storage cavity 111. After being powered on, the first heating member 2 can generate heat to heat the absorbed liquid substrate and atomize the liquid substrate, to generate the aerosol.

The first main body portion 21 absorbs the liquid substrate in the liquid storage cavity 111. The first heating portion 22 is located at an end of the first main body portion 21 away from the liquid storage cavity 111, the first heating portion 22 is connected to the first main body portion 21, and the first heating portion 22 is configured to heat the liquid substrate absorbed by the first main body portion 21, to generate the aerosol.

A specific form of the first heating member 2 may include porous ceramic and a heating circuit formed on a surface of the porous ceramic, where the porous ceramic is the first main body portion 21, and the heating circuit is the first heating portion 22. A large number of micropores are provided on the porous ceramic, to absorb the liquid substrate in the liquid storage cavity 111. The heating circuit is arranged on a side of the porous ceramic away from the liquid storage cavity 111. After being powered on, the heating circuit heats and atomizes the absorbed liquid substrate, to form the aerosol. The aerosol enters the main airway 112 from the atomization cavity 113 and is inhaled by the user. It may be understood that, the specific form of the first heating member 2 is not limited to the structure of the porous ceramic plus the heating circuit.

Referring to FIG. 2 and FIG. 3, the second heating member 3 is substantially in a long strip shape or in a flat plate shape, and the second heating member 3 is accommodated in the atomization cavity 113. Both the second heating member 3 and the first heating member 2 are mounted in the atomization cavity 113 in the thickness direction, so that the first heating member 2 and the second heating member 3 make full use of space in the thickness direction, and the second heating member 3 and the first heating member 2 are substantially arranged in parallel. The second heating member 3 is arranged corresponding to the liquid storage cavity 111, and one end of the second heating member 3 is in communication with the liquid storage cavity 111, to absorb the liquid substrate in the liquid storage cavity 111. After being powered on, the second heating member 3 can generate heat to heat the absorbed liquid substrate and atomize the liquid substrate, to generate the aerosol.

Referring to FIG. 5, the second heating member 3 includes a second main body portion 31 and a second heating portion 32, the second main body portion 31 is arranged corresponding to the liquid storage cavity 111, and the second main body portion 31 is in communication with the liquid storage cavity 111. For example, the second main body portion 31 may be in communication with the liquid storage cavity 111 through a hole, or the second main body portion 31 serves as a partition between the liquid storage cavity 111 and the atomization cavity 113, to implement communication between the second main body portion 31 and the liquid storage cavity 111.

A specific form of the second heating member 3 may include porous ceramic and a heating circuit formed on a surface of the porous ceramic. A large number of micropores are provided on the porous ceramic, to absorb the liquid substrate in the liquid storage cavity 111. The heating circuit is arranged on an atomization surface on a side of the porous ceramic away from the liquid storage cavity 111. After being powered on, the heating circuit heats and atomizes the absorbed liquid substrate, to form the aerosol. The aerosol enters the main airway 112 from the atomization cavity 113 and is inhaled by the user. In an optional suitable example, the atomization surface on the side of the porous ceramic is a flat surface, and the heating circuit extends in a length direction of the flat surface. It may be understood that, the specific form of the second heating member 3 is not limited to the structure of the porous ceramic and the heating circuit.

When only one heating member is arranged, if the heating member is damaged or malfunctions, the aerosol-generating device 100 cannot be used. In this application, two heating members are arranged. If one of the heating members is damaged, the other heating member can still be normally used, so that the remaining liquid substrate can continue to be atomized without affecting normal use of the aerosol-generating device 100. In addition, the two heating members can simultaneously work, and can simultaneously atomize the liquid substrate, so that an aerosol volume output per unit time can be increased.

Referring to FIG. 2, the first energy storage member 4 is substantially in a cylindrical shape, and in the width direction, the first energy storage member 4 is located on a side of the liquid storage portion 11, and both the first energy storage member 4 and the liquid storage portion 11 extend in the length direction and are arranged in parallel. The first energy storage member 4 extends in the length direction, so that the aerosol-generating device 100 can be prevented from being too thick. The first energy storage member 4 is electrically connected to the first heating member 2 and the second heating member 3 separately, to provide electric energy required for heat generation of the first heating member 2 and the second heating member 3.

The first energy storage member 4 may be a fixed mounted battery, or the first energy storage member 4 may be a removable battery. A specific form of the first energy storage member 4 includes, but is not limited to, a lithium ion battery, a button battery, or an alkaline dry battery.

Referring to FIG. 2, the air inlet member 6 is substantially in a block shape, and in the length direction, the air inlet member 6 is located at one end of the liquid storage portion 11. Because the liquid storage portion 11 only defines a part of the atomization cavity 113, the atomization cavity 113 is jointly defined by the air inlet member 6 and the liquid storage portion 11. An air inlet channel 61 is defined on the air inlet member 6, one end of the air inlet channel 61 is in communication with the outside, and the other end of the air inlet channel 61 is in communication with the atomization cavity 113, so that external air can enter the atomization cavity 113 from the air inlet channel 61, thereby providing airflow for the aerosol to flow.

A first air outlet hole 611 and a second air outlet hole 612 are spaced apart at the other end of the air inlet channel 61, and both the first air outlet hole 611 and the second air outlet hole 612 are in communication with the atomization cavity 113. The first air outlet hole 611 is provided corresponding to the first heating member 2, to provide an appropriate air inlet volume for the first heating member 2. The second air outlet hole 612 is provided corresponding to the second heating member 3, to provide an appropriate air inlet volume for the second heating member 3.

A distance from the first air outlet hole 611 to the first heating member 2 can be reduced, and a distance from the second air outlet hole 612 to the second heating member 3 can be reduced, so that the airflow can flow through the first heating member 2 or the second heating member 3.

In some examples, at least a part of the first air outlet hole 611 is staggered from the first heating member 2 in the width direction, that is, projections of the first air outlet hole 611 and the first heating member 2 in a horizontal plane are at least partially non-overlapping, so that the first air outlet hole 611 and the main airway 112 are located on two sides of the first heating member 2. Similarly, at least a part of the second air outlet hole 612 is staggered from the second heating member 3 in the width direction, so that the second air outlet hole 612 and the main airway 112 are located on two sides of the second heating member 3. In this way, the air inlet member 6 can guide the airflow to flow through the first heating member 2 or the second heating member 3 from two sides of the atomization cavity 113 and reach the main airway 112 located in the center, thereby reducing retention of the aerosol on the two sides of the atomization cavity.

The second energy storage member 5 extends in the width direction, so that the aerosol-generating device 100 has thin thickness. The second energy storage member 5 is electrically connected to the first heating member 2 and the second heating member 3 separately, to provide electric energy required for heat generation of the first heating member 2 and the second heating member 3.

Referring to FIG. 8, because the liquid storage portion 11 and the second energy storage member 5 are arranged side by side in the length direction, a span of the atomization cavity 113 located at one end of the liquid storage portion 11 close to the second energy storage member 5 in the width direction is close to a width dimension of the aerosol-generating device 100. Both the first heating member 2 and the second heating member 3 accommodated in the atomization cavity 113 extend in the width direction, and the first heating member 2 and the second heating member 3 are arranged in parallel, to make full use of the dimension in the width direction.

Referring to FIG. 7 again, the main airway 112 includes a first segment 112a, a second segment 112b, and a third segment 112c.

A liquid storage cavity 111, a main airway 112, and at least a part of an atomization cavity 113 are defined in the interior of the liquid storage portion 11, the liquid storage cavity 111 is for storing a liquid substrate, the atomization cavity 113 is a space for atomizing the liquid substrate, and the liquid substrate is atomized in the atomization cavity 113 and produces an aerosol. One end of the main airway 112 is in communication with the atomization cavity 113, so that the aerosol generated in the atomization cavity 113 can enter the main airway 112, and the other end of the main airway 112 is in communication with the outside, so that a user can inhale the aerosol in the main airway 112 through the other end of the main airway 112. The first heating member 2 is arranged in the atomization cavity 113, where the first heating member 2 is in communication with the liquid storage cavity 111, to absorb the liquid substrate in the liquid storage cavity 111 and perform heating and atomization, to generate the aerosol.
