Referring to fig. 1, an embodiment of the present application provides an aerosol-generating device in which an aerosol-generating device 100 is mounted, the aerosol-generating device 100 being configured to absorb and heat an aerosol-generating substrate to generate an aerosol for use by a user. The aerosol-generating substrate is a liquid including, but not limited to, materials for medical, health, wellness, and cosmetic purposes, e.g., aerosol-generating substrates are medical fluids, oils (selected according to practical protection protocols).

As shown in fig. 1 to 3 or fig. 4 to 6, the atomizing assembly 100 includes a base 20, a liquid inlet pipe 40, and a heat generating module 60. The liquid inlet pipe 40 is a hollow tubular structure with two open ends, the base 20 is connected to an open end of the liquid inlet pipe 40 in a matching manner, an atomization cavity 41 and an air flow channel 43 are formed in the liquid inlet pipe 40, the air flow channel 43 is communicated with the atomization cavity 41 and the other open end of the liquid inlet pipe 40, and a liquid inlet hole 45 communicated with the atomization cavity 41 is formed in the side wall of the liquid inlet pipe 40. In this manner, aerosol-generating substrate external to the atomizing assembly 100 may enter the atomizing chamber 41 through the liquid inlet aperture 45 and then be absorbed and heated by the heat generating module 60 to atomize the aerosol.

The heat generating module 60 includes a heat generating member 62 and a liquid guiding member 64. The liquid guide 64 is made of porous material such as cotton core, ceramic or glass, and the liquid guide 64 has a hollow columnar structure, and a liquid guide channel 641 penetrating the end surfaces of both ends of the liquid guide 64 in the axial direction is formed in the liquid guide 64. In some embodiments, the heat generating element 62 is accommodated in the liquid guide channel 641 and covers the inner wall of the liquid guide channel 641, and the aerosol-generating substrate flowing into the atomizing chamber 41 from the liquid inlet 45 can penetrate the heat conducting structure from outside to inside to reach the heat generating element 62. In other embodiments, the heat generating element 62 is circumferentially wrapped around the outer sidewall of the liquid guide 64, and the aerosol-generating substrate may penetrate the liquid guide 64 from inside to outside to reach the heat generating element 62. In other embodiments, when the liquid guide 64 is formed by a cotton core, the liquid guide 64 may not need to have the liquid guide channel 641 (as shown in fig. 7). It is to be appreciated that the shape of the liquid guide 64 is not limited thereto, and in other embodiments, the liquid guide 64 may be an approximately cylindrical structure such as an elliptical cylinder, a prismatic cylinder, or the like.

It should be noted that, the liquid guiding member 64 in fig. 1 to 3 may be formed of a material having a low structural strength such as cotton core or artificial fiber, and the liquid guiding member 64 in fig. 4 to 6 may be formed of a material having a high structural strength such as ceramic or glass.

As described in the background art, the conventional heating element 62 is a heating element formed by processing a metal plate by chemical etching, laser/mechanical engraving, stamping, etc., and compared with the element such as the spring heating wire 6161, the aerosol generated by heating has obvious advantages in terms of taste evaluation indexes such as aroma reduction degree, aroma concentration, aroma fineness, etc., so that the heating element is widely used.

In use, the heat-generating element 62 is assembled by winding it from a flat surface into a major arc shape, and the heat-generating element 62 has an axially extending notch to prevent shorting. However, at the same time, the heating element 62 has no continuous support structure in the circumferential direction of the major arc, which results in defects of low structural strength, easy deformation, etc., thus affecting the consistency of the aerosol-generating device provided with the heating element 62, reducing the stability of the suction life and the mouthfeel, and limiting the application range of the heating element 62.

Referring to fig. 8 and 9, in order to solve the above-mentioned problem, the heating element 62 of the present application includes a heating body 61 and an intermediate support 63. The heating body 61 is wound around a central axis L to form a hollow column structure, and the heating body 61 has a core heating area a circumferentially surrounding the central axis L. The intermediate support 63 passes circumferentially around the central axis L through the core heating zone a and when the heating element 62 is in the energized state, the heating body 61 is able to heat up the aerosol-generating substrate under the influence of electrical energy, the intermediate support 63 then being in a short-circuited state without the passage of electrical current. The core heating area a refers to a main area of the heating body 61 that generates heat after being electrified.

In this way, the middle supporting piece 63 penetrating through the core heating area a along the circumferential direction effectively improves the structural strength of the heating piece 62, so that the heating piece 62 is not easy to deform, the consistency of the aerosol generating device provided with the heating piece 62 is further improved, the stability of the suction life and the taste of the aerosol generating device is improved, and the application range of the heating piece 62 is enlarged. Moreover, since no current passes through the intermediate support 63, no additional power loss is caused, thereby ensuring an effective power supply to the core heating area and an atomization efficiency.

Specifically, the heat generating body 61 includes a first electrical connection portion 612, a second electrical connection portion 614, and a heat generating portion 616. The second electrical connection portion 614 and the first electrical connection portion 612 are axially spaced apart from each other at opposite ends of the heat generating body 61, and the heat generating portion 616 is connected between the first electrical connection portion 612 and the second electrical connection portion 614, and the heat generating portion 616 forms a core heat generating area a for heating the aerosol-generating substrate. The first electrical connection portion 612 and the second electrical connection portion 614 are connected to the positive and negative poles of the power source through the lead 66 (shown in fig. 3), respectively, so that the heat generating body 61 forms a current loop.

According to the preferential routing of the current path, the current flows from the first electrical connection portion 612 through the heating portion 616 into the second electrical connection portion 614 without passing through the intermediate support 63, so that the intermediate support 63 is shorted, no current flows through the intermediate support 63, and the intermediate support 63 does not cause additional power loss while improving the structural strength of the heating member 62, thereby ensuring effective power supply of the core heating region and ensuring atomization efficiency. Further, since the influence of the resistance of the intermediate support 63 on the circuit is not considered, the intermediate support 63 can be set to a large width to provide a sufficient supporting force.

Further, the heat generating body 61 includes at least two heat generating portions 616, all the heat generating portions 616 are connected in parallel between the first electrical connection portion 612 and the second electrical connection portion 614, and each heat generating portion 616 forms a core heat generating area.

Specifically, all heating portions 616 are sequentially arranged around the central axis along the circumferential direction, each heating portion 616 includes at least two heating wires 6161 and a connecting member 6163, all heating wires 6161 in the same heating portion 616 are arranged at intervals along the axial direction, each heating wire 6161 extends along an arc track in a wavy, linear or arc shape, and all heating wires 6161 in the same heating portion 616 jointly define a heating area. The connecting piece 6163 is in a sheet structure extending along the axial longitudinal direction, and the heating wires 6161 belonging to the same heating part 616 are electrically connected through the connecting piece.

In this way, the heating wires 6161 generate heat under the action of electric energy to heat the aerosol generating substrate, and the connecting piece 6163 can play a certain supporting role while electrically connecting two adjacent heating wires 6161. The intermediate support 63 passes through the connecting member 6163 between two heating wires 6161 adjacent in the axial direction in the circumferential direction and connects the respective heating portions 616, so as to function to improve the structural strength of the heating member 62.

In some embodiments, the first electrical connection 612 includes a first support 6121 and a first connection 6123. The first supporting portion 6121 is in an annular structure around the central axis, one end of the first connecting portion 6123 is connected with the first supporting portion 6121, and the other end of the first connecting portion 6123 is connected between two adjacent heating portions 616. The second electrical connection portion 614 includes a second supporting portion 6141 and a second connection portion 6143, the second supporting portion 6141 is in an annular structure around the central axis, one end of the second connection portion 6143 is connected to the second supporting portion 6141, and the other end of the second connection portion 6143 is connected between two adjacent heating portions 616.

In this way, the first electrical connection portion 612 and the second electrical connection portion 614 can improve the structural strength of the axial end of the heat generating member 62 while functioning as electrical connections. Since the liquid guide 64 formed of the cotton core has a low hardness and is more easily deformed, the first and second electric connection portions 612 and 614 are preferably used in combination with the liquid guide 64 formed of the cotton core.

Further, in order to reduce heat loss caused by the existence of the first electrical connection portion 612 and the second electrical connection portion 614, the first electrical connection portion 612 and/or the second electrical connection portion 614 are provided with a hollow groove 615, so that the heat loss area is reduced while the liquid guide member 64 is effectively supported, the pulling force is balanced, and deformation of the atomizing assembly 100 is avoided. Specifically, in one embodiment, the first supporting portion 6121 and the first connecting portion 6123 of the first electrical connecting portion 612, and the second supporting portion 6141 and the second connecting portion 6143 of the second electrical connecting portion 614 are respectively provided with a hollow slot 615 extending along the length direction.

Referring to fig. 10 and 11, in some other embodiments, the first electrical connection portion 612 and/or the second electrical connection portion 614 are in a sheet-like structure, and the first electrical connection portion 612 and/or the second electrical connection portion 614 are connected between two adjacent heat generating portions 616. The first electrical connection portion 612 and the second electrical connection portion 614 of the above-described embodiment have a small area and cannot improve the effective supporting force, and thus are used in combination with the liquid guide 64 having a high structural strength formed of a material such as ceramic, glass, or the like. Because the areas of the first and second electrical connections 612 and 614 are small, the heat loss area can be minimized while the electrical connection requirements are fulfilled, thereby improving the atomization efficiency and the aerosol generation.
