The receiving chamber is used to receive the heating component 1, and when the heating component 1 is received in the receiving chamber, the power supply component 2 is respectively electrically connected to the positive electrical connector 14 and the negative electrical connector 15 in the heating component 1 through the first output electrode and the second output electrode, thereby supplying power to the electric heating element, causing the electric heating element to generate heat and causing the aerosol generating substrate in the heating component 1 to generate aerosol.

[0056] The aerosol generating device further comprises a mouthpiece 3, at least a portion of which can be held in the mouth of a user, wherein the mouthpiece 3 is fluidly connected to the receiving chamber, and the user can inhale the aerosol generated by the heating component 1 into the oral cavity by sucking the mouthpiece 3.

[0057] The first aspect of this application can be referred to Figure 2-Figure 6In the provided heating component 1, the electric heating element includes a substrate 12 and a heating element 13 arranged on the substrate 12. The substrate 12 has a first surface 121 and a second surface 122, and the aerosol generating matrix 11 is supported by the first surface 121, so as to be maintained on the first surface 121. The positive electrical connector 14 and the negative electrical connector 15 are electrically connected to the opposite ends of the heating element 13, respectively. Wherein, when the heating component 1 is received in the receiving bin, the second surface 122 is arranged facing the first output electrode and the second output electrode of the power supply component 2, and at least part of the electrical connector is exposed on the second surface 122, so that when the heating component 1 is received in the receiving bin, the electrical connector exposed on the second surface 122 can be electrically connected to the output electrodes of the power supply component 2.

[0058] Specifically, the electrical connector includes a first electrode electrically connected to the heating element 13 and a second electrode at least partially exposed on the second surface 122, the electrical connector is electrically connected to the output electrode of the power supply component 2 through the second electrode, and the second electrode is at least partially exposed on the second surface 122. Further, the positive electrical connector 14 includes a positive second electrode 141, and the negative electrical connector 15 includes a negative second electrode 151. When the heating component 1 is connected to the receiving chamber, the positive second electrode 141 is electrically connected to the first output electrode of the aerosol generating device, and the negative second electrode 151 is electrically connected to the second output electrode of the aerosol generating device.

[0059] Based on the first aspect, at least one of the positive second electrode 141 and the negative second electrode 151 is connected to the substrate 12 and exposed on the second surface 122. For example, it can be referred to Figure 2 , Figure 4 and Figure 6 , the positive second electrode 141 is connected to the substrate 12 and exposed on the second surface 122, so that there is no need to reserve space for the positive second electrode 141 on the first surface 121, and the positive second electrode 141 does not occupy the space of the first surface 121, so that the first surface 121 can hold and accommodate more aerosol generating substrates 11. Or, for example, you can refer to Figure 2 , Figure 4 and Figure 6 The negative second electrode 151 is connected to the substrate 12 and exposed on the second surface 122, so there is no need to reserve space on the first surface 121 for setting the negative second electrode 151. The negative second electrode 151 does not occupy the space of the first surface 121, so that the first surface 121 can maintain and accommodate more aerosol generating substrates 11.

[0060] The positive second electrode 141 and the negative second electrode 151 may both be connected to the substrate 11 and exposed on the second surface 122 .

[0061] Based on the first aspect, in one embodiment, reference may be made to Figure 2-Figure 5, the heating element 13 is disposed on the first surface 121, supported and held by the first surface 121, and at least a portion of the aerosol-generating substrate 11 is disposed on the heating element 13, so that the heating element 13 and the aerosol-generating substrate 11 can be in direct contact, and the heating element 13 is disposed between the aerosol-generating substrate 11 and the substrate 12, and the substrate 11 can support and hold the aerosol-generating substrate 11 through the heating element 13. Based on this, the heating element 13 can be a resistive heating element or the heating element 13 can include an infrared radiation layer.

[0062] Among them, the resistance heating element can generate Joule heat when powered. Suitable resistance heating elements include but are not limited to: semiconductors, such as doped ceramics, conductive ceramics (such as molybdenum disilicide), carbon, graphite, metals, metal alloys, and composite materials made of ceramic materials and metal materials. Such composite materials may include doped or undoped ceramics. Examples of suitable doped ceramics include doped silicon carbide.

[0063] The resistance heating element may be formed by coating and printing a resistance paste on the first surface 121 of the substrate 12 and then curing the same. The resistance heating element may be formed by pasting a resistance film on the first surface 121 of the substrate 11.

[0064] The infrared radiation layer can be arranged on the first surface 121 of the substrate 11 by pasting, coating, printing and other processes. The infrared radiation layer can generate heat energy when powered on, and then generate infrared rays of a certain wavelength, for example, infrared rays of 0.75 μm to 1000 μm. When the wavelength of the infrared ray matches the absorption wavelength of the aerosol generating matrix, the energy of the infrared ray is easily absorbed by the aerosol generating matrix. In the embodiment of the present application, the wavelength of the infrared ray is not limited, for example, it can be infrared rays of 8 μm to 15 μm, or it can be far infrared rays of 1.5 μm to 400 μm. The thickness of the infrared radiation layer can be 30μm-50μm; the infrared radiation layer can be coated on the first surface 121 of the substrate 12 by mixing tin tetrachloride, tin oxide, antimony trichloride, titanium tetrachloride and anhydrous copper sulfate in a certain proportion; or the infrared radiation layer can include a silicon carbide ceramic layer, a carbon fiber composite layer, a zirconium-titanium oxide ceramic layer, a zirconium-titanium nitride ceramic layer, a zirconium-titanium boride ceramic layer, a zirconium-titanium carbide ceramic layer, an iron oxide ceramic layer, an iron nitride ceramic layer, an iron boride ceramic layer, an iron carbide ceramic layer, a rare earth oxide ceramic layer, a rare earth nitride ceramic layer, a rare earth boride ceramic layer, a rare earth carbide ceramic layer, a nickel-cobalt oxide ceramic layer, a nickel-cobalt nitride ceramic layer, a nickel-cobalt boride ceramic layer, a nickel-cobalt carbide ceramic layer or a high silicon molecular sieve ceramic layer; the infrared radiation layer can also be a coating of other existing materials.

[0065] In this embodiment, if the positive second electrode 141 is connected to the substrate 12 and exposed on the second surface 122, the positive second electrode 141 and the heating element 13 are disposed on opposite sides of the substrate 12. Figure 3 The positive electrical connection member 14 further includes a positive first electrode 143 electrically connected to the positive second electrode 141 , wherein the positive first electrode 143 is disposed on the first surface 121 and electrically connected to the heating element 13 at the first surface 121 .

[0066] Further, as an example, you can refer to Figure 3 The substrate 12 is provided with a first through hole connecting the first surface 121 and the second surface 122, and the positive electrical connector 14 further includes a positive connection electrode 142, which is located in the first through hole and electrically connects the positive first electrode 143 and the positive second electrode 141. Figure 3 In the cross-sectional schematic diagram of the heating assembly 1, the positive first electrode 143, the positive connecting electrode 142 and the positive second electrode 141 are roughly combined into a "I" shape, and can also be combined into a "ㄈ" shape or a step shape. It should be noted that in other examples, the positive connecting electrode 142 can be arranged on the periphery of the substrate 12.

[0067] Similarly, if the negative second electrode 151 is connected to the substrate 11 and exposed on the second surface 122, the negative second electrode 151 and the heating element 13 are disposed on opposite sides of the substrate 11. Based on this, reference may be made to Figure 3 , the negative electrical connection member 15 further includes a negative first electrode 153 electrically connected to the negative second electrode 151, wherein the negative first electrode 153 is disposed on the first surface 121 and electrically connected to the heating element 13 on the first surface 121.

[0068] Further, as an example, reference may be made to Figure 3 , the substrate 12 is provided with a second through hole communicating the first surface 121 and the second surface 122, the negative electrical connection member 15 further includes a negative connection electrode 152, the negative connection electrode 152 is located in the second through hole, and the negative connection electrode 152 electrically connects the negative first electrode 153 and the negative second electrode 151. In one embodiment, the negative first electrode 153, the negative connection electrode 152, and the negative second electrode 153 are roughly combined into a "工" shape, and of course, they can also be combined into an "ㄈ" shape or a stepped shape, etc. It should be noted that in other examples, the negative connection electrode 152 can be disposed on the periphery of the substrate 12.

[0069] Based on the first aspect, in another embodiment, reference may be made to Figure 7 and Figure 8 , the heating element 13 is disposed on the second surface 122, supported and held by the second surface 122, the aerosol generating substrate 11 can be directly disposed on the first surface 121, so that the substrate 12 is disposed between the heating element 13 and the aerosol generating substrate 11. In order to reduce power consumption, the heating element 13 can include an infrared radiation layer, and at least a part of the substrate 12 can transmit or reflect infrared rays, so that the infrared rays radiated by the infrared radiation layer can be directed to the aerosol generating substrate 11, thereby heating the aerosol generating substrate 11. In this embodiment, the positive electrical connection member 14 and the negative electrical connection member 15 can both be completely disposed on the second surface 122. As an example, the substrate 12 includes glass or quartz, so that at least a part of it is transparent.

[0070] Based on the first aspect, in one embodiment, reference may be made to Figure 4-Figure 6 , the positive electrical connection member 14, the heating element 13, and the aerosol generating substrate 11 all have a plurality of them, and the plurality of aerosol generating substrates 11 are disposed corresponding to the plurality of heating elements 13 one by one, so that the heating element 13 can heat the aerosol generating substrate 11 one by one, causing the corresponding aerosol generating substrate 11 to generate aerosol. Among them, one negative electrical connection member 15 is electrically connected to a plurality of heating elements 13 at the same time, and the plurality of heating elements 13 are respectively electrically connected to different positive electrical connection members 14.

[0071] Correspondingly, the number of first output electrodes and the number of second output electrodes in the aerosol generating device are respectively equal to the number of positive electrical connectors 14 and the number of negative electrical connectors 15. When the heating component 1 is coupled with the aerosol generating device, the positive electrical connector 14 in the heating component 1 is electrically connected to the first output electrodes in the aerosol generating device in a one-to-one correspondence, and the negative electrical connector 15 in the heating component 1 is electrically connected to the second output electrodes in the aerosol generating device in a one-to-one correspondence.

[0072] As an example, a plurality of aerosol generating substrates 11 are disposed on the same side of the negative electrical connector 15 .

[0073] As an example, see Figure 4 Among the multiple aerosol generating substrates 11, some of the aerosol generating substrates 11 are first aerosol generating substrates 111, and some of the aerosol generating substrates 11 are second aerosol generating substrates 112, wherein the first aerosol generating substrate 111 and the second aerosol generating substrate 112 are arranged on opposite sides of the negative electrical connector 15.

[0074] In the first aspect, the substrate 12 may be in a sheet or plate shape, the first surface 121 and the second surface 122 may both be planes, and the first surface 121 and the second surface 122 may be arranged opposite to each other.

[0075] In the first aspect, the resistivity of the first electrode is much smaller than the resistivity of the heating element 13, so that when power is obtained, the temperature of the first electrode is lower than the temperature of the area on the heating element 13 that is offset from the first electrode. In order to make the aerosol generating substrate 11 heated evenly, the aerosol generating substrate 11 is offset from the first electrode, that is, offset from the positive first electrode 143 and also offset from the negative first electrode 153.

[0076] The second aspect of this application can refer to Fig. 9 and Fig.10In the provided heating assembly 1, the electric heating element includes a conductive ceramic 16, which can generate Joule heat when powered, and has a relatively large hardness, and can support the aerosol generating substrate 11, and the positive electrical connector 14 and the negative electrical connector 15 can be directly disposed on the conductive ceramic 16 and electrically connected to the conductive ceramic 16. The conductive ceramic 16 has a first surface 121 and a second surface 122, the positive electrical connector 14 is electrically connected to the conductive ceramic 16 and is at least partially disposed on the second surface 122 of the conductive ceramic 16, the negative electrical connector 15 is electrically connected to the conductive ceramic 16 and is at least partially disposed on the second surface 122 of the conductive ceramic 16, and the aerosol generating substrate 11 is disposed on the first surface 121 of the conductive ceramic 16. Thus, the aerosol generating substrate 11 and the positive electrical connector 14 are arranged on different surfaces of the conductive ceramic 16, and the aerosol generating substrate 11 and the negative electrical connector 15 are arranged on different surfaces of the conductive ceramic 16, so that the positive electrical connector 14 and the negative electrical connector 15 do not occupy the first surface 121 of the conductive ceramic 16, so that the first surface 121 can retain more aerosol generating substrate 11.

[0077] Based on the second aspect, in one embodiment, the first surface 121 and the second surface 122 are perpendicular to each other, and there are two second surfaces 122 , which are arranged opposite to each other.

[0078] Based on the second aspect, in one embodiment, reference may be made to Fig. 9 and Fig.10 The first surface 121 and the second surface 122 are arranged opposite to each other.

[0079] Based on the first aspect or the second aspect, in one embodiment, the heating component 1 also includes a temperature detector, which is arranged on the second surface 122 to detect the temperature of the second surface 122. The temperature detector is electrically connected to the controller on the circuit board 22 to transmit the detected temperature data to the controller. The controller can control the output power of the power supply 21 to the electric heating element according to the temperature data, thereby controlling the temperature of the electric heating element.

[0080] Based on the first aspect or the second aspect, in one embodiment, the processor on the circuit board 22 electrically connects the positive electrical connector 14 and the negative electrical connector 15, for example, electrically connects the positive second electrode 141 and the negative second electrode 151, to obtain electrical parameters of the electric heating element related to temperature. The electrical parameters may be the resistivity, resistance value, current or voltage of the electric heating element, so that the temperature of the electric heating element can be judged based on the electrical parameters, or the output power of the power supply to the electric heating element can be controlled based on the electrical parameters or the temperature of the electric heating element, thereby controlling the temperature of the electric heating element.

Furthermore, it is possible for a person of ordinary skill in the art to make improvements or changes based on the above description, and all such improvements and changes should fall within the scope of protection of the claims attached to the present application.
