An aerosol generating device generally comprises a shell, an atomizing core, a liquid storage component and a battery. The shell is provided with a suction nozzle, and a fog outlet hole is provided in the suction nozzle. The atomizing core is installed in the liquid storage component. The atomizing core and the suction nozzle are communicated with each other, and an airway allowing air flow is provided in the atomizing core. The liquid storage component is used to store aerosol generating matrix. The atomizing core comprises a liquid guide rope, on which an electric heating wire is wound, and the liquid guide rope is used to adsorb the aerosol generating matrix in the liquid storage component. The electric heating wire is electrically connected to the battery. When used, the battery supplies power to the electric heating wire, and the aerosol generating matrix atomizes at a high temperature of the electric heating wire to produce aerosol, so that it can be smoked.
In order to avoid dry burning of the electric heating wire caused by insufficient liquid supply, a person skilled in the art adds another atomizing core in the existing liquid storage component. Two atomizing cores are arranged in parallel at an interval, each atomizing core is located in a ventilation channel, and the two atomizing cores works alternatively when working. However, when a user smokes the aerosol atomized by one of the atomizing cores, it also passively smokes air on an air path of the other atomizing core, resulting in low aerosol concentration and poor taste.
The present invention aims to provide an atomizing core with a dual heating structure and an aerosol generating device with which high aerosol concentration and good taste can be obtained.
In a first aspect, a solution with which the present invention solves the above problem is to construct an atomizing core with a double heating structure, wherein the atomizing core comprises a first atomizing core, a second atomizing core and a connecting part, wherein the first atomizing core and the second atomizing core are used for atomizing aerosol generating matrix; a first end of the connecting part is connected with the first atomizing core in a plugging manner, a second end of the connecting part is connected with the second atomizing core in a plugging manner, and the second atomizing core is connected with the first atomizing core through the connecting part.
In a second aspect, also disclosed in the present invention is an aerosol generating device, wherein the aerosol generating device comprises a shell and an atomizing core with a double heating structure, a liquid storage chamber for storing aerosol generating matrix is provided in the shell; the atomizing core with a double heating structure is located in the liquid storage chamber for atomizing the aerosol generating matrix in the liquid storage chamber, and the atomizing core with a double heating structure is the atomizing core with a double heating structure according to the above first aspect.
The present invention has the following beneficial effects: the atomizing core with a double heating structure of the present invention is cleverly matched with the first atomizing core and the second atomizing core through the connecting part, wherein the first end of the connecting part is connected with the first atomizing core in a plugging manner, the second end of the connecting part is connected with the second atomizing core in a plugging manner, the first atomizing core is connected with the second atomizing core, and when working, and no matter whether the first atomizing core and the second atomizing core work in a time-sharing manner or at the same time, the aerosol is discharged from the same ventilation channel; therefore compared with the prior art, the aerosol has the high concentration and the good taste. In addition, when assembling, the first end of the connecting part is firstly assembled with the first atomizing core in a plugging manner, and then the second end of the connecting part is connected with the second atomizing core, so that it is easy to assemble, the layout of the respective wire is easy, the first atomizing core and the second atomizing core are prevented from interacting with each other, and the production efficiency is high.
The present invention is described below in combination with the attached drawings, wherein:
The present invention is described in detail below in combination with the attached drawings and embodiments.

The first atomizing core 1 comprises a first outer sleeve 11, a first liquid guide part 12, a first electric heating element 13 and a first wire 14. A first end of the first outer sleeve 11 is provided with a first liquid guide notch 111. When assembling, the first liquid guide part 12 is guided and positioned through the first liquid guide notch 111. When working, the aerosol generating matrix flows into the first outer sleeve 11 from the first liquid guide notch 111 and is adsorbed by the first liquid guide part 12.
The first liquid guide part 12 is installed in the first outer sleeve 11 and protrudes from the first liquid guide notch 111. The first liquid guide notch 111 comprises a first guide port 112, a second guide port 113 and a clamping port 114. The first guide port 112 is communicated with an end surface of the first end of the first outer sleeve 11, a first end of the second guide port 113 is communicated with the first guide port 112, and a second end of the second guide port 113 is communicated with the clamping port 114.
The first guide port 112 and the second guide port 113 gradually increase in a direction from an end surface of a second end of the first outer sleeve 11 to the end surface of the first end of the first outer sleeve 11. Thus, when assembling the first liquid guide part 12, an operator neither needs to worry about misalignment, nor needs to worry about excessive friction of the first liquid guide notch 111 to the first liquid guide part 12. It only simply needs to push a first end and a second end of the first liquid guide part 12 from the first guide port 112 to the clamping port 114, which improves assembly efficiency.
An outer opening interval of the second guide port 113 is smaller than an inner opening interval of the second guide port 113, that is, the interval of the second guide port 113 at an outer peripheral surface of the first outer sleeve 11 is smaller than the interval of the second guide port 113 at an inner peripheral surface of the first outer sleeve 11 at the same radial position. Thus, in the assembly process, a side surface of the first liquid guide part 12 is not easy to be affected by friction of the second guide port 113, which avoids warping due to the friction.
An orthographic projection of the first guide port 112 on a longitudinal section of the first outer sleeve 11 is in a trumpet shape, and an orthographic projection of the second guide port 113 on the longitudinal section of the first outer sleeve 11 is in a trapezoid shape. Thus, in the assembly process, a side surface of a porous liquid guide sheet is not affected by the friction of the first guide port 112 and the second guide port 113, which avoids a gap between the first liquid guide part 12 and the first outer sleeve 11 which is caused by the warping due to the friction and further leads to poor sealing and leakage problems. It is understood that the longitudinal section referred to in this example means the section perpendicular to a cross section of the first outer sleeve 11 and perpendicular to an opening direction of the first liquid guide notch 111.
The clamping port 114 is clamped on the first liquid guide part 12. The clamping port 114 is arranged along a longitudinal direction of the first outer sleeve 11, and an orthographic projection of the clamping port 114 on the longitudinal section of the first outer sleeve 11 is in a rectangular shape, so it is easier to assemble and can clamp the first liquid guide part 12 well. A length of the clamping port 114 is greater than a length of the second guide port 113, and a width of the clamping port 114 is less than a width of the second guide port 113, so as to avoid low assembly efficiency and inadequate assembly due to the long length of the second guide port 113.
A plurality of liquid guide holes 115 are arranged on the outer peripheral surface of the first outer sleeve 11, and the plurality of liquid guide holes 115 are arranged at an interval around a side wall of the first outer sleeve 11. The liquid guide holes 115 and the clamping port 114 are located at the same axial position, and a distance between the clamping port 114 and an adjacent liquid guide hole 115 is equal to a distance between adjacent liquid guide holes 115. Thus, the supply of the aerosol generating matrix is more uniform, which reduces a probability of dry burning.
The first electric heating element 13 is located in the first outer sleeve 11 and is in contact with the first liquid guide part 12. The first electric heating element 13 is wound in a cylinder shape for atomizing the aerosol generating matrix at the first liquid guide part 12. The first wire 14 is connected to the first electric heating element 13 and protrudes from the first outer sleeve 11. The first electric heating element 13 may be an electric heating wire or an electric heating sheet. The first liquid guide part 12 may be one or more liquid absorbing fiber sheets, and the liquid absorbing fiber sheets cover on the first electric heating element 13 and protrude from the first liquid guide notch 111. It is understood that the liquid absorbing fiber sheets may be made from porous materials such as cotton.
The second atomizing core 2 comprises a second outer sleeve 21, a second liquid guide part 22, a second electric heating element 23 and a second wire 24. The second outer sleeve 21 is coaxially arranged with the first outer sleeve 11. A first end of the second outer sleeve 21 is provided with a second liquid guide notch 211, and an orientation of the first liquid guide notch 111 is different from that of the second liquid guide notch 211. An angle between the orientation of the first liquid guide notch 111 and the orientation of the second liquid guide notch 211 may be 60°, 90°, 120° or 180°, etc., which can be set according to needs.
In this example, the orientation of the first liquid guide notch 111 is opposite to the orientation of the second liquid guide notch 211, that is, the angle between the orientation of the first liquid guide notch 111 and the orientation of the second liquid guide notch 211 is 180°, thus enabling the first liquid guide part 12 to better adsorb external aerosol generating matrix, and avoiding insufficient liquid supply to the first liquid guide part 12 which results in the dry burning and which is resulted as a large amount of the aerosol generating matrix on the same side flows towards the second liquid guide part 22 after the second liquid guide part 22 adsorbs the aerosol generating matrix. It is understood that in normal use, the first atomizing core 1 is located above the second atomizing core 2.
The second liquid guide part 22 is installed in the second outer sleeve 21 and protrudes from the second liquid guide notch 211. The second electric heating element 23 is located in the second outer sleeve 21 and in contact with the second liquid guide part 22. The second wire 24 is connected with the second electric heating element 23 and protrudes from the second outer sleeve 21. The first wire 14 is located outside the second outer sleeve 21. Therefore, when the first wire 14 is located in the second outer sleeve 21, a problem of affecting the assembly and affecting the atomization effect can be avoided. In this example, structures of the second outer sleeve 21 and the first outer sleeve 11 of the second atomizing core 2 are the same. Structures of the second liquid guide part 22 and the first liquid guide part 12 are the same. Structures of the second electric heating element 23 and the first electric heating element 23 are the same. Therefore, their structures would not be detailed herein. It is understood that the first electric heating element 13 and the second electric heating element 23 constitute the double heating structure; when working, the aerosol generating matrix may be atomized by generating heat alternatively; of course, it may also be atomized by working manners such as firstly controlling the first electric heating element 13 and the second electric heating element 23 to generate the heat together for a short time, and then controlling them to generate the heat alternatively. It can be set according to needs, which is not limited herein.
In addition, the second atomizing core 2 further comprises a first clamping seat 25, wherein the first clamping seat 25 is inserted in a second end of the second outer sleeve 21, the second wire 14 passes through a gap between the first clamping seat 25 and the second outer sleeve 21 and protrudes from the second outer sleeve 21, the first clamping seat 25 and an inner wall of the second outer sleeve 21 jointly clamp the second wire 24. Thus, it prevents the second wire 24 from being excessively pulled and falling off during the assembly, and a resistance value of the second electric heating element 23 from being affected during pulling.
A first end of the connecting part 3 is connected with the second end of the first outer sleeve 11 in a plugging manner, and a second end of the connecting part 3 is connected with the first end of the second outer sleeve 21 in a plugging manner, so it is not only easy to assemble, but also not easy to affect the first electric heating element 13 and the second electric heating element 23 during the assembly, which ensures the stability of resistance values thereof. The first end of the connecting part 3 is arranged on an opposite side of the second end of the connecting part 3, the connecting part 3 is provided with a vent hole 31, and the second atomizing core 2 is connected with the first atomizing core 1 through the vent hole 31, that is, the first outer sleeve 11 is connected to the second outer sleeve 21 through the vent hole 31. When working, the aerosol in the second outer sleeve 21 flows through the vent hole 31 and is then discharged through the first outer sleeve 11.
An outer peripheral surface of the connecting part 3 is provided with a positioning protruding part 32 and a limiting part 33. The first end of the connecting part 3 is inserted into the second end of the first outer sleeve 11, the second end of the connecting part 3 is inserted into the first end of the second outer sleeve 21, and the positioning protruding part 32 extends into the second liquid guide notch 211. The limiting part 33 is located between the first outer sleeve 11 and the second outer sleeve 21 and is used to restrict movement of the first outer sleeve 11 towards the second outer sleeve 21. Preferably, the second end of the connecting part 3 is abutted against the second fluid guide part 22, thus improving the reliability of the second fluid guide part 22.
During the assembly, an angle between the orientation of the first liquid guide notch 111 and the orientation of the second liquid guide notch 211211 can be ensured by inserting the positioning protruding part 32 into the second liquid guide notch 211. In addition, position limitation is carried out through the limiting part 33, thus ensuring that the first outer sleeve 11 and the second outer sleeve 21 and the connecting part 3 are assembled in place, improving the reliability of the connection, avoiding the interaction between the first atomizing core 1 and the second atomizing core 2, and improving the product yield.
Specifically, in this example, the connecting part 3 is an elastic tube, a first end of the elastic tube is detachably inserted in the first outer sleeve 11, the second end of the first outer sleeve 11 is sleeved on the first end of the elastic tube, and a second end of the elastic tube is detachably inserted in the second atomizing core 2. Thus, it is easy to assemble during the assembly and the production efficiency is improved. An outer peripheral surface of the first end of the elastic tube is provided with a plurality of annular protruding parts 34 arranged at an interval and in an annular shape, the annular protruding parts 34 are elastically abutted against an inner wall of the first outer sleeve 11 and they jointly clamp the first wire 14, the first wire 14 extends from a position between the first outer sleeve 11 and the connecting part 3 to the atomizing core with a double heating structure. Therefore, the first wire 14 can be better protected from being pinched off. The connecting part 3 can be a silicone tube, and the silicone tube is connected with the first outer sleeve 11 and the second outer sleeve 21 with interference fit, which not only has good heat resistance, but also can produce deformation under the action of an external force. Thus, it is not only easy to assemble, but also has high reliability.

The differences are as follows: the atomizing core 100 with a double heating structure in this example further comprises a second clamping seat 15, which is inserted in the first outer sleeve 11 and clamps the first wire 14 together with the first outer sleeve 11; and the second end of the connecting part 3 is provided with an avoidance notch 35, which corresponds to a position of the second liquid guide notch 211, and the first wire 14 protrudes from the avoidance notch 35, that is, the first wire 14 protrudes from a space formed by the second end of the first outer sleeve 11 and the second liquid guide notch 211, and extends outside the atomizing core 100 with a double heating structure from the avoidance notch 35. Specifically, the connecting part is the elastic tube, the first end of the elastic tube is detachably sleeved on the first outer sleeve 11, and the second end of the elastic tube is detachably sleeved on the second outer sleeve 21, so the assembly is easy, and the production efficiency is high. In addition, the connection is stable and reliable. In this example, the connecting part is a glass fiber tube formed by a braided glass fiber rope. Because the second end of the connecting tube is provided with the avoidance notch 35, the first wire 14 extends from the avoidance notch 35, it is easy to assemble and avoids the interaction between the first atomizing core 1 and the second atomizing core 2.
