As Figure 1 shown, the present application discloses a heat-not-burn atomization device 10, which includes a control component 100 and a heating component 200. The control component 100 is connected to the heating component 200, and the control component 100 drives the heating component 200 to work.

[0035] The heat-not-burn atomization device 10 further includes a housing 110. A first chamber 111 and a second chamber 112 are provided inside the housing 110. The heating component 200 is located in the first chamber 111, and the control component 100 is located in the second chamber 112.

[0036] The first chamber 111 is also used for placing an aerogel matrix for generating aerogel. The control component 100 includes a circuit board 120 and a battery 130. The battery 130 is connected to the circuit board 120, and the heating component 200 is connected to the circuit board 120. The circuit board 120 controls the battery 130 to supply power to the heating component 200, and the heating component 200 generates heat to heat the aerogel matrix to generate aerogel.

[0037] The present application also discloses a heating component 200, which can be used in the heat-not-burn atomization device 10 described above. For the heating component 200, the following embodiments are provided by the present application:

[0038] Embodiment 1:

[0039] Figure 2 It is an exploded schematic diagram of the first heating component according to the first embodiment of the present application. Figure 3 It is a cross-sectional schematic diagram of the first heating component according to the first embodiment of the present application. As Figure 2-3As shown in the figure, the present application discloses a heating element 200 of a heat-not-burn atomization device 10. The heating element 200 includes a ceramic body 210, a heating wire 230, electrode leads 240, and a metal heat-conducting structure 300. The ceramic body 210 is strip-shaped and includes a top 211, a middle 212, and a bottom 213. The heating wire 230 is disposed in the middle 212 of the ceramic body 210. The electrode leads 240 are located at the bottom 213 of the ceramic body 210 and are connected to the heating wire 230. The metal heat-conducting structure 300 is sleeved on the ceramic body 210 and covers the middle 212 and the top end of the ceramic body 210 to conduct the heat of the middle 212 of the ceramic body 210 to the top 211 of the ceramic body 210.

[0040] The applicant has found that during the heating process of the heating element 200, especially in the initial stage, even if the heating element 200 reaches the required heating temperature, the generated aerogel is still not pure enough. For example, the taste is light or there is a phenomenon of taste change. The main reason is that when the existing heating element 200 is working, when the heating wire 230 transfers heat to the outside, more heat will converge in the middle 212 of the ceramic body 210, and less heat will converge at the ends. Coupled with the fact that the ends of the ceramic body 210 dissipate heat quickly and the middle 212 dissipates heat slowly, the temperature difference between the ends and the middle 212 of the entire ceramic body 210 will differ by more than 50 degrees, resulting in different heating temperatures at different positions when heating the aerogel matrix. Since the aerogel matrix is a mixture, the component ratios of the aerogel generated at different heating temperatures are not the same. Therefore, when heated at different temperatures at different positions of the heating element 200, an ideal state of aerogel cannot be generated, resulting in a lighter taste or a taste change.

[0041] Compared with the existing heating element 200 without the metal heat-conducting structure 300, in the present application, a metal heat-conducting structure 300 is sleeved outside the ceramic body 210. The metal heat-conducting structure 300 can quickly conduct the heat of the middle 212 of the ceramic body 210 to the top 211 of the ceramic body 210, reducing the large temperature difference at different positions of the heating element 200 and achieving the effect of uniform heating. Since the heating element 200 is inserted into the aerogel matrix, when the heating element 200 is working, the aerogel matrix in contact with the heating element 200 is heated more evenly, and the components in the aerogel matrix can be heated to an ideal atomization temperature evenly, so that the generated aerogel meets the requirements more.

[0042] The heating wire 230 can be printed on the outer surface of the ceramic body 210 through a plasma printing technique. The heating component 200 further includes an insulating layer 250, which is disposed between the heating wire 230 and the metal heat conduction structure 300. This enables the heat generated by the heating wire 230 to be conducted to the metal heat conduction structure 300 more quickly, achieving the purpose of rapid and uniform heating. Moreover, arranging the insulating layer 250 between the heating wire 230 and the metal heat conduction structure 300 can prevent the heating wire 230 from coming into contact with the metal heat conduction structure 300 and causing a short circuit.

[0043] Among them, due to the better heat conduction performance of aluminum and copper, the material of the metal heat conduction structure 300 can be aluminum or electroplated copper, that is, the metal heat conduction structure 300 is an aluminum tube or a copper tube, which is sleeved on the ceramic body 210 from bottom to top. Moreover, the material of the insulating layer 250 can be an insulating material with high heat conduction performance. Exemplarily, the material of the insulating layer 250 includes one of a glaze heat-conducting silica gel sheet, heat-conducting silicone grease, heat-conducting gel, heat-conducting potting glue, and heat-conducting tape.

[0044] If the metal heat conduction structure 300 is too thin, it is difficult to fabricate in terms of technology, while if the metal heat conduction structure 300 is too thick, it will lead to a longer heat transfer time and an unclear effect of uniform heating. Especially when generating aerosol during the first heating, the heat will not be transferred in time. Therefore, the thickness of the metal heat conduction structure 300 is 0.15 - 0.3 mm. This ensures the rapid and uniform heating function of the metal heat conduction structure 300.

[0045] If the insulating layer 250 is too thick, it will cause a large heat loss, while if the insulating layer 250 is too thin, it may lead to the contact between the metal heat conduction structure 300 and the heating wire 230. Therefore, the thickness of the insulating layer 250 is 0.02 - 0.025 mm to avoid the contact between the metal heat conduction structure 300 and the heating wire 230 and improve the heat transfer speed.

[0046] The ceramic body 210 includes a conical head 214 and a columnar body 215. The shape of the conical head 214 is a cone, the shape of the columnar body 215 is a cylinder. The upper bottom surface of the columnar body 215 is connected to the bottom surface of the conical head 214. The center of the upper bottom surface of the columnar body 215 and the center of the bottom surface of the conical head 214 are located on the same vertical line, and the bottom diameter of the conical head 214 is greater than the diameter of the columnar body 215.

[0047] In this embodiment, the metal heat conduction structure 300 only covers the columnar body 215. The difference between the bottom radius of the conical head 214 and the bottom radius of the columnar body 215 is d1, and the sum of the thickness of the heating wire 230, the thickness of the insulating layer 250, and the thickness of the metal heat conduction structure 300 is d2, and d1 is equal to d2.

[0048] In simple terms, the conical head 214 can make it easier to insert the heating component 200 into the aerogel matrix. The outer surface of the metal thermal conductive structure 300 smoothly transitions with the outer surface of the conical head 214, avoiding the heating component 200 from getting stuck when plugging and unplugging the aerogel matrix, thereby achieving a smooth plugging and unplugging process.

[0049] The heating component 200 further includes a zirconia flange 400, which is fixed to the ceramic body 210 and is located on the side of the metal heat-conducting structure 300 away from the cone head 214, and one end of the metal heat-conducting structure 300 away from the cone head 214 abuts against the zirconia flange 400. The zirconia flange 400 can fix the metal heat-conducting structure 300 on the ceramic body 210 to prevent the metal heat-conducting structure 300 from falling off, and the outer wall of the zirconia flange 400 is used to be fixedly connected to the housing 110 to fix the heating component 200 in the first chamber 111.

[0050] Furthermore, due to the low thermal conductivity of zirconia, the heat of the metal heat-conducting structure 300 can be prevented from being transferred to the zirconia flange 400 , thereby avoiding heat loss.

[0051] Figure 4 is a cross-sectional schematic diagram of the second heating component of the first embodiment of the present application, such as Figure 4 As shown, of course, it is also possible that the heating wire 230 is not arranged on the outer wall of the ceramic body 210, the ceramic body 210 is hollow inside to form a chamber, the heating wire 230 is arranged on the inner wall of the ceramic body 210, and the heat-conducting structure is directly sleeved and adhered to the ceramic body 210.

[0052] In this way, there is no need to set the insulating layer 250, and fewer steps are required. Compared with the solution of setting the heating wire 230 on the outer wall of the ceramic body 210, setting the heating wire 230 on the inner wall of the ceramic body 210 can simplify the preparation process of the heating component 200 and improve the preparation yield of the heating component 200.

[0053] Figure 5 Schematic diagram of the first heating wire of the first embodiment of the present application. Figure 5 As shown, in order to further reduce the temperature difference between the middle portion 212 of the ceramic body 210 and the end portion of the ceramic body 210 , the present application also improves the heating wire 230 .

[0054] Exemplarily, the extension direction of the middle part 212 of the ceramic body 210 towards the top 211 and the bottom 213 of the ceramic body 210 is the first direction. The heating wire 230 is wound around the outer surface of the ceramic body 210. Along the first direction, the wire width of the heating wire 230 gradually decreases.

[0055] In this way, when the heating component 200 is working, the resistance of the heating wire 230 corresponding to the top 211 position of the ceramic body 210 is greater, the resistance of the heating wire 230 corresponding to the middle part 211 position of the ceramic body 210 is relatively low, the heat generation of the heating wire 230 corresponding to the top 211 position of the ceramic body 210 is more, and the heat generation of the heating wire 230 corresponding to the middle part 211 position of the ceramic body 210 is relatively low, thereby reducing the temperature difference between the middle part 212 and the top 211 of the ceramic body 210.

[0056] Of course, it is also possible. As Figure 6 shown, the extension direction of the middle part 212 of the ceramic body 210 towards the top 211 and the bottom 213 of the ceramic body 210 is the first direction. The heating wire 230 is wound around the outer surface of the ceramic body 210. Along the first direction, the wire pitch of the heating wire 230 gradually decreases.

[0057] In this way, when the heating component 200 is working, the heating wire 230 corresponding to the top 211 position of the ceramic body 210 is denser, the heating wire 230 corresponding to the middle part 211 position of the ceramic body 210 is relatively sparse, the heat generation corresponding to the top 211 position of the ceramic body 210 is more, and the heat generation corresponding to the middle part 211 position of the ceramic body 210 is relatively low, thereby reducing the temperature difference between the middle part 212 and the top 211 of the ceramic body 210.

[0058] Figure 7 is a schematic diagram of a metal heat conduction structure according to the first embodiment of the present application. As Figure 7 shown, a plurality of metal protrusions 310 are provided on the outer surface of the metal heat conduction structure 300. The shape of the metal protrusions 310 is hemispherical. The extension direction of the middle part 212 of the ceramic body 210 towards the top 211 and the bottom 213 of the ceramic body 210 is the first direction, and along the first direction, the density of the metal protrusions 310 gradually decreases.

[0059] First, it can increase the outer surface area of the metal heat conduction structure 300 and the amount of aerogel generated. Second, due to the high density of the metal protrusions 310 in the middle 212 of the corresponding ceramic body 210, the heat dissipation is fast; the density of the metal protrusions 310 at the top 211 of the corresponding ceramic body 210 is low, and the heat dissipation is slow, thereby further reducing the temperature difference between different positions of the heating component 200.

[0060] Embodiment 2:

[0061] Figure 8 It is a schematic diagram of a heating component according to the second embodiment of the present application. As Figure 8 shown, different from the first embodiment, the metal heat conduction structure 300 is provided on the outer wall of the conical head 214 and the outer wall of the column body 215 of the ceramic body 210.

[0062] Exemplarily, the ceramic body 210 includes a conical head 214 and a column body 215. The shape of the conical head 214 is a cone, and the shape of the column body 215 is a cylinder. The upper bottom surface of the column body 215 is connected to the bottom surface of the conical head 214. The center of the upper bottom surface of the column body 215 and the center of the bottom surface of the conical head 214 are located on the same vertical line, and the bottom diameter of the conical head 214 is equal to the diameter of the column body 215; the shape of the metal heat conduction structure 300 matches the shape of the ceramic body 210 and is sleeved on the conical head 214 and the column body 215.

[0063] Compared with the solution of the first embodiment, the shape of the metal heat conduction structure 300 in this embodiment matches the shape of the ceramic body 210. Simply put, the metal heat conduction structure 300 also has a conical head 214 of a cone and a column body 215 of a cylinder, so that after the metal heat conduction structure 300 is sleeved on the ceramic body 210, it can completely cover the conical head 214 in contact with the aerogel matrix of the ceramic body 210 and the column body 215 in contact with the aerogel matrix of the ceramic body 210, thereby completely avoiding the situation of different heating temperatures at different positions when heating the aerogel matrix.

[0064] It should be noted that the inventive concept of the present application can form a very large number of embodiments. However, due to the limited space of the application documents, it is impossible to list them all. Therefore, on the premise of no conflict, the above-described embodiments or technical features can be arbitrarily combined to form new embodiments. After the combination of each embodiment or technical feature, the original technical effect will be enhanced.

[0065] The above content is a further detailed description of the present application in combination with specific optional implementation manners. It cannot be determined that the specific implementation of the present application is only limited to these descriptions. For those of ordinary skill in the technical field to which the present application belongs, without departing from the concept of the present application, several simple deductions or substitutions can still be made, and all should be regarded as belonging to the protection scope of the present application.
