As shown in fig. 1 and 2, the present application discloses a heat generating module for heating and baking a heat generating non-combustion aerosol-forming substrate; the heat generating module is mainly composed of a heat generating component and a heat resistant filler 12.

As shown in fig. 1 and 2, in the embodiment of the present disclosure, the heating assembly is composed of a heating body 111 and an electromagnetic induction coil 115, wherein the electromagnetic induction coil 115 is used for heating the heating body 111, and the heating body 111 can emit heat under the heating of the electromagnetic induction coil 115 to heat the aerosol generating substrate 30, so as to achieve the purpose of heating without burning.

The heat generating body 111 is a material having a high thermal conductivity and capable of generating heat by electromagnetic induction, and for example, the heat generating body 111 may be made of metal copper, aluminum, or the like. In an alternative example, as shown in fig. 3, the electromagnetic induction coil 115 may be an electromagnetic coil disposed outside the heat generating body 111, and the electromagnetic coil may be disposed in contact with or spaced from the heat generating body, for example, the electromagnetic induction coil 115 may be fixed outside the heat generating body 111 by being sleeved or embedded; in some alternative examples, the electromagnetic induction coils 115 may include one or more electromagnetic induction coils 115, and the number of electromagnetic induction coils 115 is not particularly limited in the present application, for example, in order to realize the temperature control of the heat generating body 111 in different areas, the heat generating component may include two electromagnetic coils respectively sleeved on the upper and lower ends of the heat generating body 111.

In a specific example, the heat generating body 111 is an annular sleeve structure, and a receiving channel 112 penetrating the heat generating body 111 is axially formed in the middle of the heat generating body, for example, the receiving channel 112 may be a cylindrical channel, and the interior of the receiving channel 112 is used for receiving the aerosol generating substrate 30; in use, the aerosol-generating substrate 30 may be received from one end of the receiving channel 112, with the aerosol-generating substrate 30 being secured within the receiving channel 112 by manual, additional securing structure or structural design within the receiving channel 112; for example, in an alternative example, the inner diameter of the accommodating channel 112 is designed to be equal to or slightly larger than the outer diameter of the aerosol-generating substrate 30, so that the aerosol-generating substrate 30 can be clamped by the inner wall of the accommodating channel 112 after being inserted into the accommodating channel 112, so as to avoid the aerosol-generating substrate 30 from being detached from the accommodating channel 112.

When the aerosol-generating substrate 30 is fixed in the heat-generating body 111, the heat-generating body 111 is heated by the electromagnetic field generated by the electromagnetic induction coil 115, and the aerosol-generating substrate 30 positioned in the accommodation channel 112 can be heated by the heat emitted from the heat-generating body 111, so that the aerosol-generating substrate 30 can be atomized and aerosol can be generated in a heated and non-combusted state; it will be appreciated that the aerosol generating substrate 30 is a material that generates smoke when heated to a set temperature and may be, but is not limited to, tobacco, herbs, or derivatives thereof, and the like, and the present application is not particularly limited.

In the embodiment disclosed in the present application, as shown in fig. 1, the surface of the heating body 111 is provided with a plurality of filling windows 113 arranged at intervals along the circumferential direction thereof, the filling windows 113 are in a hollowed-out state when no filler is present, that is, the accommodating channel 112 can be communicated with the outside of the heating body 111 by means of the filling windows 113, the filling windows 113 are located at the middle part of the outer circumferential surface of the heating body 111 and do not extend to two ends of the heating body 111, that is, two ends of the filling windows 113 have a certain distance from two ends of the heating body 111; the axial direction of the heat generating body 111 is described as the vertical direction, that is, both the upper and lower sides of the filling window 113 are solid portions of the heat generating body 111. In a more specific example, as shown in fig. 1, the filling window 113 is an elongated rectangular window; it is understood that the filling window 113 is not limited to a rectangular window, and in alternative examples, the filling window 113 may be semicircular, wavy, etc.

As shown in fig. 1 and 2, when the filling window 113 is filled with the filler 12, the outer circumferential surface of the heat generating body 111 can form a continuous and closed surface, and the heat resistance of the heat generating filler 12 is greater than that of the heat generating body 111, and no heat is generated under electromagnetic induction adjustment, i.e., when heat is transferred per unit area in unit time, the heat transferred through the heat generating filler 12 is smaller than that transferred through the heat generating body 111. The thermal resistance fillers 12 are arranged at intervals, so that the two ends of the heating main body 111 are not completely blocked by the heat conducting components, and heat transfer is not completely blocked under the condition of reducing heat conduction.

According to the application, the heat resistance filler 12 with low heat conductivity coefficient and high heat resistance is arranged in the middle of the heating main body 111, so that on one hand, the area of a heating area when the aerosol generating substrate 30 is heated is reduced, and meanwhile, the heating value of the middle part of the heating main body 111 can be reduced, the baking amount of moisture in the middle part of the aerosol generating substrate 30 is reduced, and the flue gas temperature is further reduced; on the other hand, the thermal resistance filler 12 located in the middle portion increases the thermal resistance of the upper and lower ends of the heating body 111, so that the two ends of the heating body 111 can be heated and controlled respectively to realize zone heating, and then the heating temperatures of different areas can be adaptively adjusted based on the characteristics or heating stages of the aerosol generating substrate 30, so that the heating body 111 can meet the heating requirements under various conditions, and the utilization rate of the aerosol generating substrate 30 is improved and the flue gas temperature is reduced under the condition of ensuring sufficient heating.

In an alternative embodiment, the thermal conductivity of the thermal resistive filler 12 is 0.02-6W/mK, and the thermal resistive filler 12 may be a material that satisfies the thermal conductivity, for example, the thermal resistive filler 12 may be, but is not limited to, a mixture of one or both of a heat resistant plastic and a ceramic; or a heat-resistant plastic is filled in a part of the filling window 113, and a ceramic is filled in another part of the filling window.

Since the filling window 113 is disposed around the heating body, in some alternative designs, the filling window 113 may extend along the axis of the heating body 111 to form a long strip structure, so that more filling windows 113 may be arranged in the circumferential direction of the heating body 111 and more heat-resistant fillers 12 may be disposed in the circumferential direction under the condition that the area of a single heating window is fixed.

In some embodiments, the heat generating body 111 has a virtual center line 114 extending in a radial direction and capable of equally dividing the heat generating body 111, and a symmetry axis of the filling window 113 in the radial direction of the heat generating body 111 is offset from the virtual center line 114; taking fig. 2 as an example, when the vertical direction is taken as the axis of the heat generating body 111, the virtual center line 114 is the horizontal center line of the heat generating body 111, and the filling window 113 is located above the virtual center line 114, that is, the heat-resistant filler 12 is located above the outer peripheral surface of the heat generating body 111; more specifically, taking the example that the outer peripheral surface developed image of the heat generating body 111 is rectangular, the virtual center line 114 is a horizontal center line of the rectangle, and the filling window 113 is located at a position above the outer peripheral surface of the heat generating body 111.

In some alternative designs, in order to avoid uneven heat distribution of the heat generating body 111 in the circumferential direction, the filling windows 113 are arranged at equal intervals in the circumferential direction of the heat generating body 111; that is, the gaps on the peripheral surface of the heat generating body 111 are uniform in size between any adjacent heat resistant fillers 12 (i.e., between any two adjacent filler windows 113), so that the uniformity of heat distribution on the peripheral surface of the heat generating body 111 can be ensured. For example, in the example of fig. 1 and 2, sixteen filling windows 113 filled with the heat-resistant filler 12 are provided, and sixteen heat-conducting windows are symmetrically arranged on any radial line (for example, the radial line may be the virtual center line 14) of the heat-generating body 111, and are equally spaced around the heat-generating body 111.

On the basis of the above, the present application further provides an aerosol generating device, as shown in fig. 4, comprising the above heating module; the electric control module 20, the electric control module 20 and the electromagnetic induction coil 115 in the heating module are connected through circuit structures such as electrodes or wires. For example, the electronic control module 20 described above may include one or more of a power source (which may be a built-in power source or a connector for an external power source), a circuit board, and a controller.

In a more specific example, as shown in fig. 4 and 5, the aerosol generating device further comprises a housing 21, wherein an atomization cavity and an electrical cavity are arranged in the housing 21, and the electronic control module 20 is fixedly arranged in the electrical cavity inside the housing 21; the heat generating module is disposed in the atomizing chamber of the housing 21, for example, in some examples, as shown in fig. 3, the heat generating module further includes a mounting seat 22 disposed in the atomizing chamber for fixing the heat generating module, and a clamping structure is disposed in the mounting seat 22 for clamping the heat generating module, and a certain gap may exist between an outer sidewall of the heat generating module and an inner sidewall of the mounting seat 22 as a heat insulation gap.

With continued reference to fig. 4 and 5, the top of the housing 21 is further provided with a feed port 211, and the top of the accommodating channel 112 is communicated with the feed port 211 on the housing 21, and the aerosol-generating substrate 30 can be inserted into the accommodating channel 112 through the feed port 211; in some examples, the inlet 211 may also be used as a channel for air to enter the accommodating channel 112, alternatively, in other embodiments, a separate air inlet may be formed on the housing 21 and communicate with the accommodating channel 112, which is not limited in this disclosure.

It will be appreciated that in alternative examples, conventional components or structures of other aerosol generating devices, such as insulation layers, air inlet channels, air outlet channels, heat exchangers, etc., may be disposed or mounted within the housing 21 of the aerosol generating device, and the present application is not limited thereto, so that further description thereof will be omitted.

During operation, the aerosol generating substrate 30 is inserted into the accommodating channel 112 through the feed inlet 211, and the heating module is controlled to heat by the electronic control module 20 at the moment, when the aerosol generating substrate 30 enters the accommodating channel 112, the middle section of the aerosol generating substrate 30 corresponds to the region where the thermal resistance filler 12 is located, so that during heating, the baking of moisture in the middle of the aerosol generating substrate 30 can be reduced, and the purpose of reducing the temperature of flue gas is achieved; in addition, in some alternative embodiments, electromagnetic induction coils 115 may be disposed at the upper and lower ends of the heating body 111, and the areas on both sides of the heat-resistant filler 12 may be subjected to the influence of the heat-resistant filler 12 with a low thermal conductivity in the middle, so that the heating temperatures may be set during heating, thereby performing zone control on the upper and lower ends of the heating body 111, so as to improve the utilization rate of the aerosol-generating substrate 30.

According to the application, the aerosol generating substrate 30 is circumferentially heated, so that the temperature of generated smoke can be effectively reduced under the condition that the aerosol generating substrate 30 is sufficiently heated, the occurrence of mouth scalding is avoided, and the user experience is improved.
