[0035] The application will be described in further detail below with specific reference to the drawings. Like elements in different embodiments are denoted by like reference numerals. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the application. However, those skilled in the art will readily recognize that many of the specific details presented herein can be replaced by other elements, materials, methods, etc. In some instances, well-known structures and methods have not been described in detail in order to avoid obscuring the application. It is intended that the specification and examples be considered as exemplary only, with the true scope of the application being indicated by the following claims.

[0036] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various embodiments, and the steps of the operations involved in each embodiment can be sequentially adjusted or modified in a manner that can be easily apparent to those skilled in the art. Therefore, the specification and drawings are only intended to clearly describe one embodiment, and do not mean that the composition and / or order is necessary.

[0037] The serial numbers of components in this paper, such as "first", "second", etc., are only used to distinguish the described objects, and do not have any order or technical meaning. The "connection" and "coupling" in this application include direct and indirect connection (coupling) unless otherwise specified.

[0038] The heating device in this application is used to heat and atomize the aerosol generating rod to generate aerosol. The heating device can be installed in a matching atomization equipment for use. When the aerosol generating rod is inserted into the heating device, the end inserted into the heating device is the air inlet end, and the end outside the heating device is the suction end. The aerosol generating rod has an atomization substrate inside. When the user performs a suction action through the suction end, the gas at the air inlet end can be sucked into the aerosol generating rod and flow to the suction end along the extension direction of the aerosol generating rod, while carrying the atomized aerosol to the suction end.

[0039] By heating the heating base, the heat exchange core and the heating element of the heating device, in the state that the aerosol generating stick is inserted into the heating groove of the heating base, the airflow can enter the bottom of the heating groove along the air passage groove on the inner side wall of the heating groove, and then flow into the air inlet end of the aerosol generating stick through the air passage hole on the heat exchange core. At the same time, the heating element supplies heat to the heating base and the heat exchange core, so that the airflow is preheated when flowing along the air passage groove, and then heated again to form a hot airflow with a higher temperature when flowing through the air passage hole of the heat exchange core, so as to form a hot airflow heating after entering the inside of the aerosol generating stick, and realize the heating and atomization of the aerosol generating stick. By arranging the heat exchange core in the heating groove, the incoming airflow can be subjected to multiple segmented heating, and a high-temperature hot airflow is formed, which has higher heating efficiency, and can also alleviate the airflow disturbance at the bottom of the heating groove, so that the hot airflow enters the inside of the aerosol generating stick more uniformly and stably, which is beneficial to improve the heating and atomization effect.

[0040] Some embodiments of the heating device and the atomization equipment provided in the present application are provided below in combination with the drawings.

[0041] In the embodiments of the first aspect of the present application, a heating device 100 is provided. As shown in Figure 1 , Figure 2 and Figure 3 , the heating device 100 comprises a heating base 11, a heat exchange core 12 and a heating element 13. The heating base 11 adopts a hollow structure with one side opening, that is, the heating base 11 has a heating groove 111 inside, and in the first direction, one end of the heating base 11 is an insertion port 1121 communicating with the heating groove 111, and the other end opposite to the insertion port 1121 is a closed end 1122; the heating groove 111 is used for inserting the aerosol generating stick 31, and the inner side wall of the heating groove 111 has an air passage groove 113 communicating with the insertion port 1121, when the aerosol generating stick 31 is inserted into the heating groove 111, the external gas can still flow into the heating groove 111 through the air passage groove 113, and flow into the inside of the aerosol generating stick 31 through the air inlet end 311 inserted into the heating groove 111.

[0042] Among them, as shown in Figure 4 and Figure 5In the example shown in FIG. 1, the heat exchange core 12 is located in the heating groove 111 close to the closed end 1122, and in the state where the aerosol generating stick 31 is inserted into the heating groove 111, the heat exchange core 12 is located between the aerosol generating stick 31 and the closed end 1122. A plurality of air passage holes 121 are formed on the heat exchange core 12, and the plurality of air passage holes 121 are all through in the first direction. After the airflow flows from the air passage groove 113 to the side of the heat exchange core 12 facing the closed end 1122, the flow direction of the airflow can be changed, and the airflow can pass through the plurality of air passage holes 121 on the heat exchange core 12 and then flow into the aerosol generating stick 31. At least part of the heating element 13 is arranged at the closed end 1122 of the heating base 11. The heating element 13 can be electrically connected with the power supply device and heated in the powered state to heat the heating base 11 and the heat exchange core 12, and then heat the incoming airflow to form a high-temperature hot airflow through the heat conduction of the heating base 11 and the heat exchange core 12.

[0043] It should be noted that the shape, size, etc. of the air passage groove 113 and the air passage hole 121 can be set according to specific needs. In actual application, the size of the heating groove 111 is matched with the aerosol generating stick 31 so that the aerosol generating stick 31 can enter the heating groove 111.

[0044] It can be understood that in actual application, since the heating base 11 needs to be connected and assembled with related components in the atomization device, the thermal conductivity coefficient of the material of the heating base 11 cannot be particularly high, and it is difficult to heat the airflow to a high temperature, so the heating effect of the heating base 11 alone is limited.

[0045] The heating device 100 in the embodiment can form a preheating process for the airflow by forming the air passage groove 113 on the side wall of the heating groove 111 of the heating base 11 and arranging the heat exchange core 12 with the air passage hole 121 in the heating groove 111, and using the bottom heating method, so that in the state where the aerosol generating stick 31 is assembled in the heating groove 111, the external air can flow into the bottom of the heating groove 111 while being heat exchanged with the side wall of the heating groove 111 through the air passage groove 113, and then the airflow is further heated by the heat exchange core 12 while passing through the air passage hole 121, so that a high-temperature hot airflow can be formed, the heating efficiency is higher, and the airflow can be more stable and orderly after passing through the air passage hole 121 and entering the aerosol generating stick 31, so that the heating is more uniform, which is beneficial to improve the heating and atomization effect of the aerosol generating stick 31.

[0046] In further embodiments of the present application, as shown in FIG. 2, Figure 4 and Figure 5As shown, the heating groove 111 includes an insertion section 1111, a heat exchange section 1112 and a gas guiding section 1113 which are sequentially communicated in the first direction. The insertion section 1111 is communicated with the insertion port 1121 and used for accommodating the aerosol generating stick 31; the gas guiding section 1113 is located in the heating groove 111 close to the closed end 1122 and used for guiding the airflow; the heat exchange section 1112 is located between the gas guiding section 1113 and the insertion section 1111 and used for accommodating the heat exchange core 12. When the aerosol generating stick 31 is inserted into the insertion section 1111 of the heating groove 111, the heat exchange core 12 corresponds to the air inlet end 311 of the aerosol generating stick 31, the air passage groove 113 forms an air inlet channel, the airflow can flow from the air passage groove 113 to the gas guiding section 1113 and be guided to the air passage hole 121 passing through the heat exchange core 12, and then flow into the inside of the aerosol generating stick 31 from the air inlet end 311 of the aerosol generating stick 31.

[0047] It can be understood that, since the air passage groove 113 is communicated with the outside at the insertion port 1121 of the heating groove 111, if the position opposite to the air inlet end 311 of the aerosol generating stick 31 in the heating groove 111 is blocked, the airflow movement is not smooth, and a part of the hot airflow may flow reversely and flow out from the insertion port 1121, which can cause heat loss and affect the heating uniformity and heating efficiency of the aerosol generating stick 31. The gas guiding section 1113 in the embodiment can provide sufficient space for the flow of the hot airflow, which can effectively prevent the airflow from being blocked and ensure that the airflow can smoothly pass through the air passage hole 121 of the heat exchange core 12 and flow to the air inlet end 311 of the aerosol generating stick 31.

[0048] In further embodiments of the present application, as examples in Figure 1 and Figures 3 to 5 , a first protruding structure 114 is arranged in the gas guiding section 1113 of the heating groove 111, the first protruding structure 114 extends to the connection between the gas guiding section 1113 and the heat exchange section 1112 in the first direction to serve as a stopper, the first protruding structure 114 abuts against one end of the heat exchange core 12 facing the gas guiding section 1113, and the first protruding structure 114 limits the heat exchange core 12 to prevent the heat exchange core 12 from entering the gas guiding section 1113, so that the gas guiding section 1113 has sufficient space for the airflow to flow and prevents the gas guiding section 1113 from being blocked to affect the airflow entering the heat exchange core 12.

[0049] It should be noted that, in actual application, the number of the first protruding structure 114 can be one or more, and the specific position of the first protruding structure 114 is not limited to the position shown in Figure 4 , and can be arranged according to specific use needs.

[0050] Further, as examples in Figures 4 to 6In the example shown in FIG. 11, a plurality of air passage grooves 113 are circumferentially spaced apart on the inner side wall of the heating groove 111, and each air passage groove 113 extends in the first direction, so that a plurality of air inlet channels extending in the first direction can be formed in the circumferential direction of the aerosol generating stick 31 when the aerosol generating stick 31 is inserted into the heating groove 111. Correspondingly, a plurality of first protruding structures 114 are arranged in the air guide section 1113, each first protruding structure 114 is located between two circumferentially adjacent air passage grooves 113, and each first protruding structure 114 is connected with the inner side wall and the bottom wall of the air guide section 1113, and the first protruding structure 114 as a whole extends towards the central axis of the air guide section 1113 in the first direction, so that the gap space between any two adjacent first protruding structures 114 is in communication with a corresponding air passage groove 113, and the hot gas flow in each air passage groove 113 can flow in the first direction during the suction process, and pass through the gap space between the corresponding two first protruding structures 114 to flow to the heat exchange core 12. Specifically, the plurality of air passage grooves 113 are equally spaced in the circumferential direction of the heating groove 111, and correspondingly, the plurality of first protruding structures 114 are also equally spaced in the circumferential direction of the heating groove 111.

[0051] Through the above arrangement, the position of the first protruding structure 114 can be matched with the air passage groove 113, so as to avoid the hot gas flow in the air passage groove 113 being blocked by the first protruding structure 114 when entering the air guide section 1113, and the gas flow can move more smoothly. Since the first protruding structure 114 is connected with the inner side wall and the bottom wall of the air guide section 1113, when the hot gas flow passes through the gap space between the first protruding structures 114, the first protruding structure 114 can play a guiding role, so that the movement direction of each gas flow is clear and will not flow to adjacent positions, which can effectively avoid the vibration phenomenon caused by turbulent gas flow, and is beneficial to improve the stability of the aerosol generating stick 31 in the heating and atomization process and improve the use experience.

[0052] In further embodiments of the present application, as shown in Figure 1 , Figure 3 and Figure 4 , the plurality of air passage holes 121 of the heat exchange core 12 are arranged in an array form, so that the plurality of air passage holes 121 can be relatively uniformly distributed. The array arrangement form includes but is not limited to a ring array form and a matrix form. For example, Figure 3For example, the heat exchange core 12 adopts a cylindrical structure, and the plurality of air holes 121 are arranged in the form of a ring array with the center axis of the heat exchange core 12 as the axis, which can make full use of the limited space, increase the number of air holes 121 as much as possible, and meet the uniform arrangement form. Of course, according to specific use requirements and different shape structures of the heat exchange core 12, the air holes 121 can also adopt other arrangement forms. For example, when the heat exchange core 12 is in the shape of a cuboid, the plurality of air holes 121 are arranged in the form of a matrix to adapt to the shape of the heat exchange core 12. Among them, the air holes 121 are arranged in a staggered manner with the first protruding structure 114 to avoid the first protruding structure 114 blocking the normal air inlet of the air holes 121.

[0053] In addition, it should be noted that the hole type of the air hole 121 is not limited to the round hole structure shown in the figure, and can also be a square hole or other shape according to needs. Figure 3

[0054] In further embodiments of the present application, as shown in Figure 2 and Figure 7 The heating element 13 includes a heating circuit 131, a first electrical connection point 132 and a second electrical connection point 133. The first electrical connection point 132 and the second electrical connection point 133 are respectively connected to the two ends of the heating circuit 131, at least part of the heating circuit 131 is located on the end face of the closed end 1122 of the heating base 11 and is in a curved or broken line shape, or the heating circuit 131 simultaneously includes a curved portion and a broken line portion; the first electrical connection point 132 and the second electrical connection point 133 are used to connect with the power supply device to form an electrical connection between the heating circuit 131 and the power supply device. When the power supply device supplies power to the heating element 13, the heating circuit 131 generates heat and heats the heating base 11; the heating base 11 is made of infrared ray transparent material, so that the infrared ray emitted by the heating circuit 131 can pass through the heating base 11 into the heating groove 111 to heat the heat exchange core 12 and the airflow. Among them, the number of heating elements 13 can be one or more; the heating circuit 131 can be processed and manufactured by printing or spraying process, and different arrangement modes can be adopted according to specific heating requirements in actual application. In addition, the material of the heating base 11 includes but is not limited to glass, ceramic, and the heating base 11 made of the above-mentioned materials is suitable for infrared ray to pass through and has high thermal conductivity, which is beneficial to heating the airflow in the heating groove 111.

[0055] Further, in a specific implementation, the number of heating circuits 131 is set to be multiple. For example Figure 8 ​In the example shown in FIG. 1, the number of heat-generating lines 131 is two, and the number of first electrical connection points 132 and second electrical connection points 133 is one. One end of each heat-generating line 131 is connected to the first electrical connection point 132, and the other end is connected to the second electrical connection point 133, so that the two heat-generating lines 131 share a set of first electrical connection points 132 and second electrical connection points 133, forming a parallel form. The above method can reduce the number of first electrical connection points 132 and second electrical connection points 133, facilitating connection.

[0056] In another specific implementation, the number of heat-generating lines 131, first electrical connection points 132, and second electrical connection points 133 is multiple, for example Figure 9 In the example shown in FIG. 1, two sets of heat-generating lines 131, first electrical connection points 132, and second electrical connection points 133 are provided, wherein each heat-generating line 131 has one first electrical connection point 132 and one second electrical connection point 133 connected to both ends, forming two independent heating elements 13. The two sets of heating elements 13 can be electrically connected to the power supply device, and the two sets of heating elements 13 can be controlled to work independently according to needs, for example, one set of heating elements 13 can be controlled to heat, or both sets of heating elements 13 can be controlled to heat, and the flexibility of heating operation is higher.

[0057] In the example of the second aspect of the present application, an atomization device 200 is provided, as shown in Figure 10 、 Figure 11 and Figure 12 The atomization device 200 includes a housing 21, a power supply device 22, and the heating device 100 of any one of the embodiments of the first aspect described above. The power supply device 22 and the heating device 100 are arranged in the housing 21, and the power supply device 22 is electrically connected to the heating element 13 of the heating device 100 to supply power to the heating element 13. The housing 21 is provided with an assembly opening 211 at one end of the housing 21 in the first direction, and the insertion opening 1121 of the heating device 100 is arranged correspondingly to the assembly opening 211. In use, the aerosol generating stick 31 can be inserted into the housing 21 through the assembly opening 211 and inserted into the heating groove 111 of the heating device 100, and then heated by the heating device 100 to heat and atomize the aerosol generating substrate in the aerosol generating stick 31 and generate aerosol.

[0058] Wherein, since the heating base 11 of the heating device 100 is provided with the heating groove 111 with the ventilation groove 113, when the aerosol generating stick 31 is inserted into the heating groove 111, the ventilation groove 113 can form an air inlet channel to make the airflow flow into the area close to the closed end 1122 in the heating groove 111 along the ventilation groove 113 during the suction process, and exchange heat with the heating base 11 during the inlet process, forming a preheating treatment of the airflow, and then the airflow flows to the air inlet end 311 of the aerosol generating stick 31 through the plurality of ventilation holes 121 on the heat exchange core 12, and exchanges heat with the heat exchange core 12 when flowing through the ventilation holes 121, so as to further heat the airflow to form a high-temperature hot airflow, so as to heat the inside of the aerosol generating stick 31 by the hot airflow.

[0059] The atomization device 200 in the embodiment can be used in cooperation with the aerosol generating stick 31, can alleviate airflow impact and disturbance during the air inlet process, can make the hot airflow more uniform, and can further improve the temperature of the airflow entering the inside of the aerosol generating stick 31 to form a high-temperature hot airflow, thereby improving the effect of heating and atomization and improving the user's use experience.

[0060] Further, as shown in the examples in Figure 11 and Figure 12 , according to actual use needs, a corresponding atomization cavity and an electrical cavity can also be arranged in the shell 21. The heating device 100 is arranged in the atomization cavity, and the power supply device 22 is arranged in the electrical cavity, so that the power supply device 22 and the heating device 100 are isolated from each other.

[0061] In addition, the atomization device 200 in the embodiment has all the beneficial effects of the heating device 100 in any of the above embodiments, which will not be described here again.

[0062] In further embodiments of the present application, as shown in Figures 11 to 13 , the atomization device 200 further comprises a support seat 23, the support seat 23 is arranged in the shell 21 and has a mounting cavity 231 for mounting the heating base 11, the mounting cavity 231 is open at one end in the first direction towards the assembly opening 211, so that the heating base 11 can enter the mounting cavity 231; the inner side wall of the mounting cavity 231 is connected with a support structure 232. Correspondingly, the outer side wall of the one end of the heating base 11 provided with the insertion opening 1121 has a second protruding structure 115, the second protruding structure 115 protrudes outwardly from the heating groove 111. The heating base 11 is assembled in the mounting cavity 231 of the support seat 23 in the first direction, and the second protruding structure 115 is correspondingly abutted at one end of the support structure 232 towards the assembly opening 211, so as to support the heating base 11 by the support structure 232.

[0063] Wherein, it should be noted that the second protruding structure 115 can be a continuous structure extending in the circumferential direction, as shown in Figure 13In the example provided, the second protruding structure 115 can also be a discontinuous structure in the circumferential direction, that is, it includes multiple sub-protrusions spaced apart in the circumferential direction. Correspondingly, the support structure 232 can also be a continuous structure extending in the circumferential direction, or the support structure 232 can also be a discontinuous structure in the circumferential direction, that is, it includes multiple sub-supports spaced apart in the circumferential direction. In practical applications, it can be configured according to specific usage requirements, so that the support structure 232 and the second protruding structure 115 abut against each other. Furthermore, the support structure 232 and the support base 23 can be an integrally formed structure, or they can be separate structures connected by welding or other methods.

[0064] Furthermore, such as Figures 11 to 14 As shown, the atomizing device 200 also includes a cap structure 24 and a contact element 25. The cap structure 24 has through-hole structures at both ends in the first direction. The end face of the cap structure 24 is opposite to the end face of the heating base 11 where the insertion port 1121 is located, and abuts against the heating base 11, so that the cap structure 24 communicates with the heating groove 111 of the heating base 11, allowing the aerosol generating rod 31 to pass through the cap structure 24 and be inserted into the heating groove 111 of the heating base 11 during use. The contact element 25 is disposed within the cap structure 24, and its two ends are through-hole in the first direction, forming a nested configuration with the cap structure 24. Multiple third protrusions 251 are provided on the inner wall of the contact element 25, and these protrusions are spaced apart circumferentially. The contact element 25 is made of a flexible material, capable of producing a certain degree of elastic deformation. When the aerosol generating rod 31 passes through the cap structure 24 and the contact element 25, as... Figure 12 In the example shown, the aerosol generating rod 31 passes through both the pressure cap structure 24 and the contact member 25. Multiple third protrusions 251 on the inner side of the contact member 25 abut against the outer wall of the aerosol generating rod 31, generating a certain elastic deformation. This serves to limit and fix the aerosol generating rod 31, preventing it from shaking and also preventing axial movement through contact friction. This improves the assembly stability of the aerosol generating rod 31 and avoids affecting its normal heating operation. Furthermore, in the circumferential direction, the gap between adjacent third protrusions 251 allows airflow to pass through, keeping the vent groove 113 connected to the outside for easy air intake.

[0065] It should be noted that the gland structure 24 can be a one-piece structure, or it can be adopted as follows: Figure 13 The split structure shown, namely the cap structure 24, specifically includes a cap body 241 and a cap interface 242. The cap interface 242 is located at the end of the cap body 241 facing the assembly port 211, and is positioned by a corresponding slot, and is connected to the assembly port 211 through the cap interface 242. The contact member 25 can adopt, for example, Figure 13The contact piece 25 is integrally formed of flexible material, as shown in the integrated structure. Of course, the main body of the contact piece 25 can be formed of hard material, and only the inner side wall is fixedly connected with the third protruding structures 251 of flexible material, which can also achieve the corresponding technical effects.

The first protruding structure 114 as a whole extends toward the central axis of the air guide segment 1113 in the first direction, so that the gap space between any two adjacent first protruding structures 114 corresponds to the structure of a corresponding air flow groove 113.

[0076] As shown in Figure 5 and Figure 12 , the aerosol generating stick 31 has an air inlet end 311 at one end in the first direction and a suction end 312 at the other end, and has an atomization substrate inside; in the state that the air inlet end 311 of the aerosol generating stick 31 is inserted into the heating groove 111, when the user performs a suction action through the suction end 312, the gas at the air inlet end 311 can be sucked into the aerosol generating stick 31 and flow to the suction end 312 along the extension direction of the aerosol generating stick 31.

The inlet airflow enters the air passage groove 113 of the heating groove 111 through the assembly opening 211, exchanges heat with the heating base 11 during flowing along the air passage groove 113 to the air guiding cavity, and performs preheating treatment on the airflow; after the airflow enters the air guiding cavity, it can also receive heat through the bottom wall of the heating groove 111, and then change the flow direction under the guidance of the air guiding cavity and flow to the heat exchange core 12; the airflow passes through different air holes 121 on the heat exchange core 12 and flows to the air inlet end 311 of the aerosol generating stick 31, exchanges heat with the heat exchange core 12 in the air holes 121, and the temperature is further increased to form a high-temperature hot airflow. During the user's suction process, the high-temperature hot airflow is sucked into the aerosol generating stick 31 to heat the inside of the aerosol generating stick 31. The atomization substrate in the aerosol generating stick 31 is heated and atomized to generate aerosol, which moves to the suction end 312 with the airflow.

[0077] When the aerosol generating stick 31 is heated by the atomization device 200 in the present application, the external air can be heated multiple times before entering the aerosol generating stick 31, and further heated to form a high-temperature hot air flow during the process of passing through the air passage 121, so that the heating efficiency is higher, and the airflow impact and disturbance in the air guiding cavity can be offset by the heat exchange core 12, so that the airflow can enter the aerosol generating stick 31 more smoothly and orderly after passing through the air passage 121, which is beneficial to improve the heating and atomization effect of the aerosol generating stick 31.
