In the description of the present disclosure, it is to be understood that the terms “first”, “second” and the like in the specification and claims of the present disclosure and the above-mentioned drawings are intended to distinguish between similar objects and not necessarily to describe a particular order or sequence.

In the description of the present disclosure, it is to be noted that the terms “mount” and “connect” should be understood broadly, for example, a fixed connection, a detachable connection, an integrated connection, a mechanical connection, an electrical connection, a direct connection, or an indirect connection through an intermediate medium. The specific meaning of the above terms in the present disclosure will be understood in a specific way to those skilled in the art.

As shown in FIGS. 1 and 2, an atomization core according to one or more embodiments of the present disclosure atomization core is provided in an atomization channel 01 and configured to heat an atomization substrate. The atomization core includes a first heating member 1, a second heating member 2, an electrode portion 3, and a controller 4. The first heating member 1 and the second heating member 2 are both disposed in the atomization channel 01. The first heating member 1 is disposed near an outlet of the atomization channel 01, and the second heating member 2 is disposed near an atomization substrate outlet 8 of the atomization channel 01. The first heating member 1 and the second heating member 2 are connected to the controller 4 through the electrode portion 3. The controller 4 is configured to control operations of the first heating member 1 and/or the second heating member 2.

Specifically, both the first heating member 1 and the second heating member 2 are provided in the atomization channel 01 to produce heat in the atomization channel 01. The second heating member 2 is configured to heat the atomization substrate to generate aerosol.

The first heating member 1 is provided at an opening of the atomization channel 01, and is configured to equalize temperature in the atomization channel 01 and perform a secondary atomization on condensate in the atomization channel 01, thereby solving a problem of deterioration of taste of the aerosol caused by the condensate from flowing out through the outlet of the atomization channel 01 or flowing to the second heating member 2 through the atomization channel 01. The controller 4 is configured to control the first heating member 1 and the second heating member 2 to cooperate so as to perform an atomization on the condensate and the atomization substrate in the atomization channel 01, and control intermittent heating of the first heating member 1 to prevent a problem of poor atomization experience caused by a too high temperature at the outlet in the atomization channel 01.

An operation principle of the atomization core is that the controller 4 is connected to the electrode portion 3 so as to control the second heating member 2 to operate normally to meet an atomization requirement, and control the first heating member 1 to operate at intervals to raise a temperature at the outlet of the atomization channel 01, thereby reducing the generation of condensate and performing a secondary atomization to the condensate in the atomization channel 01. According to the atomization core, the first heating member 1 is provided close to the outlet of the atomization channel 01 so as to heat the condensate in the atomization channel 01, thereby solving a problem that the taste of the aerosol is poor due to the condensate in the atomization channel 01.

It should be noted that the first heating member 1 operates at intervals. Specifically, when the second heating member 2 is heated for a predetermined number of times, the controller 4 controls the first heating member 1 to operate, that is, the condensate easily exists in the atomization channel 01 when a user sucks for a predetermined number of times, and amount of the condensate in the atomization channel 01 is determined by the number of sucks. Therefore, it is possible to control the first heating member 1 to perform the second atomization on the condensate in the atomization channel 01 based on a number of suctions so as to improve the taste of the aerosol. For example, the second heating member 2 may be switch to for operation when the first heating member 1 has started up to heat for 30 times, or the second heating member 2 and the first heating member 1 both operate.

In one or more embodiments, as shown in FIGS. 1 and 2, the electrode portion 3 includes a first electrode 31, a second electrode 32, and a third electrode 33. An output terminal of the first electrode 31 is connected to the first heating member 1 and the second heating member 2, respectively, and an input terminal of the first electrode 31 is connected to the controller 4. The controller is configured to control the first heating member to operate after the second heating member operates for a period of time.

An output terminal of the second electrode 32 is connected to the first heating member 1, and an input terminal of the second electrode 32 is connected to the controller 4.

An output terminal of the third electrode 33 is connected to the second heating member 2, and an input terminal of the third electrode 33 is connected to the controller 4.

Specifically, the electrode portion 3 is configured to turn on the power supply to ensure the operations of the first heating member 1 and the second heating member 2. When the controller 4 turns on the first electrode 31 and the second electrode 32, the first heating member 1 operates to heat the atomization channel 01 near the outlet, thereby preheating the atomization channel 01 to reduce the temperature difference in the atomization channel 01, and performing the secondary atomization on the condensate in the atomization channel 01.

When the controller 4 turns on the first electrode 31 and the third electrode 33, the second heating member 2 operates to perform an atomization on the atomization substrate.

When the controller 4 turns on the first electrode 31, the second electrode 32, and the third electrode 33, the first heating member 1 and the second heating member 2 operate to ensure that the condensate in the atomization channel 01 is removed and the amount of the atomization is increased, thereby improving atomization experience of the user. It should be noted that the first heating member 1 and the second heating member 2 may be spaced or in contact in an axial direction of the atomization channel 01.

In one or more embodiments, the first heating member 1 and the second heating member 2 are spaced apart by a distance of 5 mm to 10 mm in the axial direction of the atomization channel 01.

Specifically, when a distance between the first heating member 1 and the second heating member 2 is short and a temperature difference of the first heating member 1 and the second heating member 2 is great, the first heating member 1 and the second heating member 2 are easy to influence each other, thereby causing a poor atomization effect. When the distance between the first heating member 1 and the second heating member 2 is short, the condensate easily existing at the outlet of the atomization channel 01 is easy to flow to the second heating member 2 during a start-up process of the first heating member 1, thereby affecting the atomization efficiency of the second heating member 2. When a length of the atomization channel 01 is constant and a distance between the first heating member 1 and the second heating member 2 is long, the first heating member 1 is prone to heat the aerosol at the outlet of the atomization channel 01 to a too high temperature. Therefore, the atomization effect is better when the distance between the first heating member 1 and the second heating member 2 is 5 mm to 10 mm. For example, the distance between the first heating member 1 and the second heating member 2 is 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, or 10 mm.

In one or more embodiments, a resistance R1 of the first heating member 1 and a resistance R2 of the second heating member 2 meets a formula: R1−R2=0.2˜0.4Ω, where R2 is 0.6˜1.5Ω.

Specifically, when the resistance of the first heating member 1 is greater than the resistance of the second heating member 2, it can ensure the heating efficiency of the condensate in the atomization channel 01 while ensuring that the first heating member 1 operates at intervals. For example, the resistance of the second heating member 2 is 0.6˜1.5Ω. When a resistance difference between the first heating member 1 and the second heating member 2 is 0.2˜0.4Ω, it can prevent an aerosol temperature at the outlet of the atomization channel 01 from being low when the length of the atomization channel 01 is constant, thereby ensuring the atomization experience of the user.

In one or more embodiments, both the first heating member 1 and the second heating member 2 include a mesh structure. The mesh structure extends along a circumferential direction of the atomization channel 01 for enclosing a circular mesh structure.

Specifically, both the first heating member 1 and the second heating member 2 have a circular mesh structure to increase a contact area between the first heating member 1 and the inner wall of the atomization channel 01 and a contact area between the second heating member 2 and the inner wall of the atomization channel 01, thereby improving the atomization efficiency. It should be noted that the first heating member 1 and the second heating member 2 may also include multiple circular structures along a length direction of the atomization channel 01.

In one or more embodiments, a first liquid-absorbing member 5 is provided in the atomization channel 01, and provided with a first heating channel 51 along an axial direction of the atomization channel 01. The second heating member 2 and/or the first heating member 1 are provided in the first heating channel 51.

Specifically, the first liquid-absorbing member 5 is used to guide and store atomization substrate flowing out from the substrate outlet of the atomization channel 01 so as to prevent liquid atomization substrate from flowing out from the outlet of the atomization channel 01. In addition, the first liquid-absorbing member 5 is used to collect heat generated by the second heating member 2, so that the atomization substrate is heated more sufficiently and the atomization effect is improved.

It should be noted that the first heating member 1 may be disposed in the first liquid-absorbing member 5 to perform the secondary atomization on the condensate flowing to the first liquid-absorbing member 5 from top. The first heating member 1 may be further configured to heat the atomization substrate in the first liquid-absorbing member 5 more sufficiently to enhance the atomization experience of the user. The first heating member 1 may also be disposed outside the first liquid-absorbing member 5 so as to perform the secondary atomization on the atomization substrate in the atomization channel 01, thereby preventing a problem of low concentration of the atomized substrate in the first liquid-absorbing member 5 caused by the condensate flowing into the first liquid-absorbing member 5, and improving the atomization taste.

In one or more embodiments, the second heating member 2 is disposed in the first heating channel 51.

A second liquid-absorbing member 6 is provided in the atomization channel 01, and is provided with a second heating channel 61 along the axial direction of the atomization channel 01. The first heating member 1 is provided in the second heating channel 61.

Specifically, when the first heating member 1 is disposed outside the first heating channel 51, the first heating member 1 is coated with the second liquid absorbing member 6. The second liquid absorbing member 6 is used to adsorb the condensate in the atomization channel 01, so that excessive condensate is prevented from flowing to the second heating member 2 and the condensate is heated centrally by the first heating member 1, thereby improving the heating efficiency and further improving the atomization taste. The second heating channel 61 provided in the second liquid-absorbing member 6 is used to ensure lead-out efficiency of aerosol, thereby improving the atomization experience of the user.

In one or more embodiments, the first heating channel 51 and the second heating channel 61 are arranged coaxially, and an inner diameter of the first heating channel 51 is less than or equal to an inner diameter of the second heating channel 61.

Specifically, the first heating channel 51 and the second heating channel 61 are arranged coaxially to ensure the lead-out efficiency of the generated aerosol. The inner diameter of the first heating channel 51 is less than the inner diameter of the second heating channel 61 so as to reduce flow resistance of the aerosol at the outlet and to ensure that more aerosol is leaded from the outlet to the user, thereby improving a fog effect.

Specifically, the atomizer includes an outer shell 02, an atomization core disposed within the outer shell 02, an atomization channel 01, and an atomization substrate storage unit.

The outer shell 02 and the inner shell 7 are spaced. A spaced region forms an atomization substrate storage channel 72, The atomization substrate storage channel 72 is connected to the atomization substrate storage chamber 71.

Specifically, the atomization substrate storage channel 72 for storing the atomization substrate is provided between the inner shell 7 and the outer shell 02, thereby increasing storage amount of the atomization substrate in the atomizer. In addition, the atomization substrate is stored in the atomization substrate storage channel 72, so that a phenomenon that the atomization substrate is easily inactivated close to the heat source is improved, thereby improving the atomization experience of the user.
