Description

Technical Field

[0001] The present application relates to the technical field of aerosol generation, and particularly relates to an aerosol generation device and a control method thereof. Background Art

[0002] An aerosol generation device is a device used to generate an aerosol from an aerosol generation matrix. Generally, it generates an aerosol by heating and baking the aerosol generation matrix with a heating element or by using the high-frequency vibration of ultrasonic waves. The aerosol generation matrix often has two forms: liquid and solid.

[0003] In the related art, when using a heating element to heat and bake a solid aerosol generation matrix, the baking condition of the aerosol generation matrix is mainly determined by the temperature field distribution on the heating element. In order to achieve a more flexible and differentiated (such as zone heating) baking effect, the heating element often needs to be designed with a relatively complex heating circuit, and it is difficult for the aerosol generation matrix to reach an ideal baking uniformity. Summary of the Invention

[0009] In some of these embodiments, the aerosol - generating substrate has a pre - baking portion. Before the connector and the aerosol - generating substrate jointly rotate one full circle around the axis of the aerosol - generating substrate, the baking speed of the heating element for the pre - baking portion is greater than the baking speed of the heating element for other parts of the aerosol - generating substrate.

[0010] In some of these embodiments, the heating element includes a first heating portion and a second heating portion. The length direction of the first heating portion is arranged at an angle with respect to the axis direction of the aerosol - generating substrate. The first heating portion has opposite first and second ends, and the second heating portion has opposite third and fourth ends. The first end and the fourth end are spaced along the circumferential direction of the aerosol - generating substrate and are flush in the axis direction of the aerosol - generating substrate. The second end and the third end both extend towards the pre - baking portion, and the second end and the third end are connected. The second end and the third end are used to jointly heat the pre - baking portion.

[0011] In some of these embodiments, the heating element includes a first heating portion and a second heating portion. The second heating portion is located on the side of the first heating portion away from the pre - baking portion. The first heating portion and the second heating portion are connected. The resistance of the second heating portion is less than the resistance of the first heating portion. The first heating portion is used to heat the pre - baking portion.

[0012] In some of these embodiments, the cross - sectional area of the first heating portion is smaller than the cross - sectional area of the second heating portion; or, the second heating portion includes a first part and a second part connected in parallel.

[0013] In some of these embodiments, the heating element includes a first heating wire and a second heating wire. The second heating wire is located at one end of the first heating wire close to the pre - baking portion. The second heating wire is used to heat the pre - baking portion.

[0014] In some of these embodiments, the length direction of the first heating wire is parallel to the axis direction of the aerosol - generating substrate, and the length direction of the second heating wire is arranged at an angle with respect to the axis direction of the aerosol - generating substrate.

[0015] In some of these embodiments, the length direction of the second heating wire is perpendicular to the axis direction of the aerosol - generating substrate.

[0016] In some of these embodiments, one end of the first heating wire close to the pre - baking portion is parallel and spaced from the second heating wire, and the length of the first heating wire is greater than the length of the second heating wire.

The first heating wire has opposite first and second ends, the second heating wire has opposite third and fourth ends, the second end and the third end are arranged at intervals along the circumferential direction of the aerosol generating substrate and are arranged at intervals in the axial direction of the aerosol generating substrate. The first end and the fourth end both extend towards the pre-baking part, and the distance between the first end and the fourth end along the circumferential direction of the aerosol generating substrate is less than the distance between the second end and the third end along the circumferential direction of the aerosol generating substrate.

[0018] In some of these embodiments, the first heating wire has opposite first and second ends and a connecting part located between the first end and the second end. The second end faces the pre-baking part. The second heating wire has opposite third and fourth ends. The fourth end is connected to the connecting part. The third end extends towards the pre-baking part, and the third end is arranged at intervals with the first end along the circumferential direction of the aerosol generating substrate.

[0019] In some of these embodiments, the aerosol generating device further includes a mounting member provided with a receiving hole for receiving the aerosol generating substrate. The inner hole wall of the receiving hole is arranged opposite to the heating element, and the driving assembly is arranged outside the receiving hole.

[0020] In some of these embodiments, the aerosol generating device further includes a housing, a controller, and a sensor. The housing is provided with an air outlet for receiving the aerosol generating substrate. The power member and the sensor are both electrically connected to the controller. The sensor is used to be arranged in the air outlet, and the sensor is one of a Hall sensor, a temperature sensor, or a pressure sensor.

[0021] In a second aspect, an embodiment of the present application provides a control method for an aerosol generating device as described in the first aspect, including:

[0022] Obtaining the environmental parameters of the part of the aerosol generating device for discharging the aerosol, where the environmental parameters include temperature and / or pressure; if the change amount of the environmental parameters is greater than a first preset value, then using the power member to drive the connecting member and the aerosol generating substrate to rotate together around the axis of the aerosol generating substrate, and using the heating element to bake different parts of the aerosol generating substrate;

[0023] Alternatively, obtain the usage distance between the user and the aerosol generation matrix. If the usage distance is greater than a second preset value, use the power member to drive the connection member and the aerosol generation matrix to rotate together around the axis of the aerosol generation matrix, and use the heating element to bake different parts of the aerosol generation matrix.

[0024] Alternatively, obtain the circuit signal corresponding to the heating element. The circuit signal includes at least one of voltage, current, power, and load resistance value. If the change amount of the circuit signal is greater than a third preset value, use the power member to drive the connection member and the aerosol generation matrix to rotate together around the axis of the aerosol generation matrix, and use the heating element to bake different parts of the aerosol generation matrix.

It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of this application, "a plurality of" means two or more unless otherwise specifically defined.

[0062] Reference to "an embodiment", "some embodiments" or "embodiments" in the description of this application means that a particular feature, structure or characteristic described in connection with the embodiment is included in one or more embodiments of this application. Thus, statements such as "in an embodiment", "in some embodiments", "in other some embodiments", "in still other embodiments", etc. that appear in different places in this specification are not necessarily all referring to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in another way. In addition, in one or more embodiments, specific features, structures or characteristics can be combined in any suitable manner.

[0063] To illustrate the technical solutions of this application, the following will be described in conjunction with specific drawings and embodiments.

[0064] An aerosol generating device is a device for generating an aerosol from an aerosol generating substrate. Generally, it generates an aerosol by heating and baking the aerosol generating substrate with a heating element or by using the high-frequency vibration of ultrasonic waves. The aerosol generating substrate usually has a liquid and a solid state.

[0065] In the related art, when using a heating element to heat and bake a solid aerosol generating substrate, the baking condition of the aerosol generating substrate is mainly determined by the temperature field distribution on the heating element. In order to achieve a more flexible and differentiated (such as zone heating) baking effect, it is often necessary to design the heating element with a relatively complex heating circuit and surround the aerosol generating substrate, and it is difficult for the aerosol generating substrate to achieve an ideal baking uniformity.

[0066] In view of this, the present application provides an aerosol generating device and a control method thereof. Since the heating element is used to be arranged on one side of the aerosol generating substrate and heat a part of the aerosol generating substrate, and the driving assembly includes a power member and a connecting member connected to each other, and the connecting member is used to be connected to the aerosol generating substrate, the power member can be used to drive the connecting member and the aerosol generating substrate to rotate together around the axis of the aerosol generating substrate, so that the heating element bakes different parts of the aerosol generating substrate, and thus the aerosol generating substrate can be baked more uniformly by the heating element with a simple structure.

[0067] Please refer to Figures 1 to 3 , Figure 1 FIG. is a schematic structural diagram of the aerosol generating device in the first embodiment of the present application, Figure 2 is Figure 1 a schematic connection structure diagram of the connecting member 20 and the aerosol generating substrate 00 in the aerosol generating device shown, Figure 3 is Figure 1 a schematic structural diagram of the heating element 10 in the aerosol generating device shown.

[0068] On the one hand, the first embodiment of the present application provides an aerosol generating device, including a heating element 10 and a driving assembly, and the heating element 10 is used to be arranged on one side of the aerosol generating substrate 00 and heat a part of the aerosol generating substrate 00.

[0069] The heating element 10 can be a stainless steel thick film heating element 10, whose base material is stainless steel. After applying and sintering an insulating coating on the base material, a heating circuit is applied and sintered. Alternatively, the heating element 10 can be a ceramic thick film heating element 10, whose base material is ceramic, and a heating circuit is applied and sintered on the ceramic. Alternatively, the heating element 10 can be an MCH (Metal Ceramics Heater), on which a heating circuit is applied to a green ceramic body and then co-fired, and a heating wire is inlaid in the ceramic base material. Alternatively, the heating element 10 can be a metal base material inlaid with a heating wire. To prevent short circuit between the metal base material and the heating wire, insulation protection needs to be pre-done on the local part of the metal base material or the heating wire. Alternatively, the heating element 10 can be a substrate with a heating sheet assembled by local tight fitting, and the base material thereof is not limited to metal and ceramic, and at least one of the heating sheet and the base material is an insulating material or has been pre-insulated, and a light source / infrared light source is installed locally on the base material.

[0070] The aerosol generating substrate 00 can be in a solid state, and its shape can be cylindrical, and the heating element 10 is used to heat and bake the side surface of the aerosol generating substrate 00. The length direction of the heating element 10 can be along the axis L direction of the aerosol generating substrate 00 or form an angle θ with the axis L of the aerosol generating substrate 00. The two ends of the heating element 10 respectively have an end point A and an end point B, and the heating element 10 is a single-segment heating (points A and B are connected to a power supply) both in the preheating stage and the non-preheating stage.

[0071] The driving assembly includes a connected power member and a connecting member 20, the connecting member 20 is used to be connected to the aerosol generating substrate 00, and the power member is used to drive the connecting member 20 and the aerosol generating substrate 00 to rotate together around the axis L of the aerosol generating substrate 00, so that the heating element 10 bakes different parts of the aerosol generating substrate 00.

[0072] The power member may be a cylinder or a motor, etc. The power member and the connecting member 20 may be connected by a coupling, a gear, a belt or a chain, etc. The connecting member 20 and the aerosol generating matrix 00 may be connected together by bonding or clamping.

[0073] When the aerosol generating device provided in the embodiment of the present application is in use, the connecting member 20 can be first connected to the aerosol generating matrix 00, and then a power member can be used to drive the connecting member 20 and the aerosol generating matrix 00 to rotate together around the axis L of the aerosol generating matrix 00, and the heating element 10 can be used to bake different parts of the aerosol generating matrix 00.

[0074] Since the power component can drive the connecting component 20 and the aerosol generating matrix 00 to rotate together around the axis L of the aerosol generating matrix 00, the heating element 10 can bake different parts of the aerosol generating matrix 00. Therefore, the structure of the heating element 10 does not need to be complicated, and the aerosol generating matrix 00 can be baked more evenly, thereby improving the baking uniformity.

[0075] From the above, it can be seen that the aerosol generating device provided in the embodiment of the present application, since the heating element 10 is used to be arranged on one side of the aerosol generating substrate 00 and heat a part of the aerosol generating substrate 00, and the driving assembly includes a connected power member and a connecting member 20, and the connecting member 20 is used to be connected to the aerosol generating substrate 00, so the connecting member 20 and the aerosol generating substrate 00 can be driven by the power member to rotate around the axis L of the aerosol generating substrate 00 together, so that the heating element 10 bakes different parts of the aerosol generating substrate 00, so that the aerosol generating substrate 00 can be baked more evenly by the heating element 10 with a simple structure.

[0076] The aerosol generating device provided in the embodiment of the present application is provided with a relatively simple heating element 10. By rotating the aerosol generating substrate 00, the high temperature area of ​​the heating element 10 can evenly scan the aerosol generating substrate 00, thereby achieving the effect of evenly baking the aerosol generating substrate 00.

[0077] In the first embodiment, the aerosol generating substrate 00 is provided with a stop portion 01 , and the connecting member 20 is provided with a matching portion 21 , and the matching portion 21 is used for matching and connecting with the stop portion 01 .

[0078] By adopting the above solution, the matching portion 21 can be matched and connected with the stop portion 01 , so that the connecting member 20 and the aerosol generating substrate 00 can rotate together around the axis L of the aerosol generating substrate 00 .

[0079] It is understandable that the stop portion 01 may be provided in a non-baking section of the aerosol generating substrate 00 .

[0080] Optionally, the stop portion 01 is set as a recessed portion, and the matching portion 21 is set as a raised portion; or, the stop portion 01 is set as a raised portion, and the matching portion 21 is set as a recessed portion.

[0081] With such arrangement, the fitting portion 21 can be plugged into and matched with the stop portion 01 , so that the connector 20 and the aerosol generating matrix 00 can rotate together around the axis L of the aerosol generating matrix 00 , which has a simple structure and is easy to operate.

[0082] It should be noted that the recessed portion can be set as a groove, and the raised portion can be set as a bump. The shape of the groove is adapted to the groove, and the bump is used to be inserted into the groove.

[0083] For example, the stop portion 01 is configured as a cross-shaped groove, and the matching portion 21 is configured as a cross-shaped protrusion.

[0084] In the first embodiment, the connector 20 is disposed at one end of the aerosol generating substrate 00 , the stopper 01 is disposed on the surface of the aerosol generating substrate 00 facing the connector 20 , and the mating portion 21 is disposed on the surface of the connector 20 facing the aerosol generating substrate 00 .

[0085] By adopting the above solution, the matching portion 21 can be matched and connected with the stop portion 01 only by moving the aerosol generating matrix 00 in a direction close to the connecting member 20 , which is simple and convenient to operate.

[0086] Please refer to Figures 1 to 3 In the first embodiment, the aerosol generating device further includes a mounting member 30, which is provided with a receiving hole 31, and the receiving hole 31 is used to accommodate the aerosol generating matrix 00, the inner hole wall of the receiving hole 31 is arranged opposite to the heating element 10, and the driving component is arranged outside the receiving hole 31.

[0087] By adopting the above solution, the aerosol generating substrate 00 can be limited by the accommodating hole 31 of the mounting member 30 to prevent the aerosol generating substrate 00 from shaking randomly.

[0088] Optionally, the aerosol generating device further includes a heat insulating member 40 sleeved on the mounting member 30 , and the heating element 10 is located between the mounting member 30 and the heat insulating member 40 .

[0089] With such a configuration, the heat insulating member 40 can be used to insulate the heating element 10 to avoid affecting other components of the aerosol generating device.

[0090] It should be noted that the material of the heat insulation member 40 can be other heat insulation materials such as PEEK (Poly Ether-Ether-Ketone) pipes, ceramics, mica sheets or silica gel heat insulation pads.

[0091] Please refer to Figures 1 to 3 , in the first embodiment, the aerosol generating device further includes a housing, a controller and a sensor. The housing is provided with an air outlet for accommodating the aerosol generating substrate 00. Both the power member and the sensor are electrically connected to the controller. The sensor is used to be arranged in the air outlet and is one of a Hall sensor, a temperature sensor or a pressure sensor.

[0092] By adopting the above solution, it can be detected whether the user is in contact with the aerosol generating device through the Hall sensor, or the temperature or pressure in the air outlet can be detected through the temperature sensor or the pressure sensor, so as to determine whether it is necessary to control the power member to drive the connecting member 20 and the aerosol generating substrate 00 to rotate together around the axis L of the aerosol generating substrate 00 through the controller, so that the user behavior can be monitored by the sensor to determine and ensure that the rotation behavior only occurs at an appropriate time.

[0093] It can be understood that when the user approaches the aerosol generating device, for example, when the distance between the user and the aerosol generating substrate 00 is small (such as in contact), the Hall sensor detects a signal. At this time, it is not necessary to drive the connecting member 20 and the aerosol generating substrate 00 to rotate together around the axis L of the aerosol generating substrate 00 through the power member, so as to avoid breaking the aerosol generating substrate 00. When the distance between the user and the aerosol generating substrate 00 is large, the connecting member 20 and the aerosol generating substrate 00 are driven to rotate together around the axis L of the aerosol generating substrate 00 through the power member.

[0094] It should be noted that it can also be determined or predicted whether it is necessary to drive the connecting member 20 and the aerosol generating substrate 00 to rotate together around the axis L of the aerosol generating substrate 00 through the change of voltage / current / power / load resistance value signal when the aerosol generating device is in use. The load resistance value refers to the resistance value presented by the heating element 10 in the normal working (i.e., with load) state.

[0095] Please refer to Figure 4 , Figure 4 is a schematic diagram of the connection structure between the connecting member 20 and the aerosol generating substrate 00 in the aerosol generating device in the second embodiment of the present application.

[0096] Different from the first embodiment, in the second embodiment, the stop portion 01 is set as a "cross"-shaped groove, and the matching portion 21 is set as a "-shaped" convex block.

[0097] By adopting the above solution, the engaging portion 21 and the stopping portion 01 can be engaged and connected, so that the connecting member 20 and the aerosol generating substrate 00 can rotate together around the axis L of the aerosol generating substrate 00.

[0098] Please refer to Figure 5 and Figure 6 , Figure 5 which is a schematic structural diagram of the aerosol generating device in the third embodiment of the present application, Figure 6 is Figure 5 a schematic connection structure diagram of the connecting member 20 and the aerosol generating substrate 00 in the aerosol generating device shown.

[0099] In the third embodiment, the connecting member 20 is sleeved on the aerosol generating substrate 00, the stopping portion 01 is arranged on the outer surface of the aerosol generating substrate 00, and the engaging portion 21 is arranged inside the connecting member 20.

[0100] By adopting the above solution, the engaging portion 21 and the stopping portion 01 can be engaged and connected, so that the connecting member 20 and the aerosol generating substrate 00 can rotate together around the axis L of the aerosol generating substrate 00.

[0101] It can be understood that the outer side of the connecting member 20 can be toothed for receiving the mechanical driving force of the driving member.

[0102] Among them, the connecting member 20 is sleeved on the upper section of the aerosol generating substrate 00, the stopping portion 01 is arranged as a groove, the shape of the connecting member 20 is arranged as a ring, and the engaging portion 21 is arranged as a protrusion.

[0103] Please refer to Figure 7 and Figure 8 , Figure 7 which is a schematic structural diagram of the aerosol generating device in the fourth embodiment of the present application, Figure 8 is Figure 7 a schematic connection structure diagram of the connecting member 20 and the aerosol generating substrate 00 in the aerosol generating device shown.

[0104] Different from the third embodiment, in the fourth embodiment, the connecting member 20 is sleeved on the lower end of the aerosol generating substrate 00.

[0105] By adopting the above solution, the engaging portion 21 and the stopping portion 01 can be engaged and connected, so that the connecting member 20 and the aerosol generating substrate 00 can rotate together around the axis L of the aerosol generating substrate 00.

[0106] Please refer to Figures 9 to 12 , Figure 9 which is a schematic structural diagram of the heating element 10 in the fifth embodiment of the present application, Figure 10 is Figure 9Schematic diagram of the projection area swept by the heating element 10 when preheating and baking different parts of the aerosol - generating substrate 00 Figure 11 is Figure 9 Another schematic diagram of the projection area swept by the heating element 10 when preheating and baking different parts of the aerosol - generating substrate 00 Figure 12 is Figure 9 Schematic diagram of the projection area swept by the heating element 10 when completely baking different parts of the aerosol - generating substrate 00

[0107] In the fifth embodiment, the aerosol - generating substrate 00 has a pre - baking part 02. Before the connecting member 20 and the aerosol - generating substrate 00 rotate one full circle around the axis L of the aerosol - generating substrate 00 together, the baking speed of the heating element 10 for the pre - baking part 02 is greater than the baking speed of the heating element 10 for other parts of the aerosol - generating substrate 00.

[0108] By adopting the above - mentioned scheme, before the power component drives the connecting member 20 and the aerosol - generating substrate 00 to rotate one full circle around the axis L of the aerosol - generating substrate 00 together, the degree of baking of the pre - baking part 02 can be made greater than that of other parts of the aerosol - generating substrate 00, so that the pre - baking part 02 can generate aerosol more quickly.

[0109] It should be noted that the pre - baking part 02 can be located in the upper section of the aerosol - generating substrate 00. Through the shape design of the heating element 10, by controlling the rotation angle of the aerosol - generating substrate 00, the ratio of the baking area / heating power density of the upper and lower sections of the aerosol - generating substrate 00 can be adjusted, so as to achieve concentrated baking of the pre - baking part 02 in the upper section of the aerosol - generating substrate 00 during the pre - heating stage, making the baking speed of the heating element 10 for the pre - baking part 02 greater than the baking speed of the heating element 10 for other parts of the aerosol - generating substrate 00, generating aerosol quickly, and at the same time achieving almost the same energy accumulation supply for the upper and lower sections of the aerosol - generating substrate 00 during the entire heating cycle, with uniform baking and avoiding over - baking of the pre - baking part 02 in the upper section of the aerosol - generating substrate 00.

[0110] In the fifth embodiment, the heating element 10 includes a first heating portion 101 and a second heating portion 102. The length direction of the first heating portion 101 is arranged at an angle with respect to the axis L direction of the aerosol-forming substrate 00. The first heating portion 101 has opposite first and second ends 111 and 112. The second heating portion 102 has opposite third and fourth ends 121 and 122. The first end 111 and the fourth end 122 are arranged at intervals along the circumferential direction of the aerosol-forming substrate 00 and are flush with each other in the axial direction of the aerosol-forming substrate 00. The second end 112 and the third end 121 both extend in the direction close to the pre-baking portion 02, and the second end 112 and the third end 121 are connected to each other. The second end 112 and the third end 121 are used to jointly heat the pre-baking portion 02.

[0111] By adopting the above solution, before the power member drives the connecting member 20 and the aerosol-forming substrate 00 to rotate one full circle around the axis L of the aerosol-forming substrate 00, the second end 112 and the third end 121 can jointly heat the pre-baking portion 02, so that the baking degree of the pre-baking portion 02 can be greater than that of other parts of the aerosol-forming substrate 00, thereby enabling the pre-baking portion 02 to generate aerosol more quickly.

[0112] It can be understood that the second end 112 and the third end 121 can be connected by an oblique angle or an arc. The first heating portion 101 and the second heating portion 102 can be integrally formed, and the first heating portion 101 and the second heating portion 102 are respectively different parts of the heating element 10.

[0113] In the fifth embodiment, the two ends of the first heating portion 101 respectively have an end point A and an end point B, the midpoint P1 of the first heating portion 101, one end of the second heating portion 102 has an end point C, the other end is connected to the end point A, the midpoint P2 of the second heating portion 102, the length direction of the first heating portion 101 forms an angle θ with the length direction of the second heating portion 102, the length direction of the first heating portion 101 forms an angle θ / 2 with the axis L direction of the aerosol-forming substrate 00, and the length direction of the second heating portion 102 forms an angle θ / 2 with the axis L direction of the aerosol-forming substrate 00.

[0114] Please refer specifically to Figure 10, the rectangular UVYZ is the circumferential development view of the aerosol generation substrate 00. During the preheating stage of the aerosol generation substrate 00, when the power component drives the connecting member 20 and the aerosol generation substrate 00 to rotate around the axis L of the aerosol generation substrate 00 by a small angle, such as 1 / 3 turn - 1 / 2 turn, such as 2 / 5 turn, the power density of the projection area AA’O swept by the first heating part 101 and the second heating part 102 is twice that of other scanned areas (BB’OP1 area or CC’P2O area). The average power density of the upper half scanned area AA’P2P1 is 4 / 3 times that of the lower half scanned area (BB’OP1 and CC’P2O). The centralized heating of the AA’O area can ensure that the preheating part 02 of the upper part is centrally baked and quickly heated during the preheating stage. The area of the baked area of the preheating part 02 in the upper section of the aerosol generation substrate 00 is significantly larger than the area of the baked area in the lower section of the aerosol generation substrate 00. Corresponding to the preheating stage, the heating power density / heating temperature of the baked area (or a central part of the baked area) of the preheating part 02 in the upper section of the aerosol generation substrate 00 is significantly higher than that of the baked area in the lower section of the aerosol generation substrate 00, so that the preheating part 02 in the upper section of the aerosol generation substrate 00 can be centrally heated and aerosol can be quickly generated.

[0115] Please refer specifically to Figure 11 , as another form of preheating, the rectangular UVYZ is the circumferential development view of the aerosol generation substrate 00. During the preheating stage of the aerosol generation substrate 00, when the power component drives the connecting member 20 and the aerosol generation substrate 00 to rotate around the axis L of the aerosol generation substrate 00 by 1 / 2 turn - 2 / 3 turn, such as 2 / 3 turn, the power density of the projection area AA’O1O2 swept by the first heating part 101 and the second heating part 102 is twice that of the power density of other scanned areas (BB’O1P1 area or CC’P2O2 area). The average power density of the upper half scanned area AA’P1P2 is 7 / 5 times that of the lower half scanned area BC’P2P1. The centralized heating of the AA’O1O2 area can ensure that the preheating part 02 of the upper part is centrally baked and quickly heated, and aerosol can be quickly generated.

[0116] Please refer specifically to Figure 12, after the preheating stage ends, vibration or light can be set to indicate the completion of the preheating stage. During the complete heating cycle, the effective areas of the upper scanning area and the lower scanning area are equal, and the corresponding average power densities are the same. When the power component drives the connecting member 20 and the aerosol generating substrate 00 to rotate a small angle together around the axis L of the aerosol generating substrate 00, that is, corresponding to the whole process from the start of heating to the end of heating, the aerosol generating substrate 00 rotates 1 circle or 2 circles or more. The area of the pre-baked part 02 of the upper section of the aerosol generating substrate 00 that is baked is equal to the area of the lower section of the aerosol generating substrate 00 that is baked. Corresponding to the whole heating cycle, the upper and lower sections of the aerosol generating substrate 00 have approximately the same average heating power density supply and energy accumulation supply, so that the upper and lower sections are baked thoroughly and evenly.

[0117] Only during the preheating stage, the effective areas of the upper scanning area and the lower scanning area are not equal, and the area of the upper scanning area is smaller than the area of the lower scanning area. The average power density of the upper scanning area is greater than the average density of the lower scanning area, and the average power density of the local area in the middle of the upper scanning area that is repeatedly scanned is 2 times the power density of other areas.

[0118] It should be noted that both the preheating stage and the non-preheating stage are such that the heating element 10 has single-segment heating (only 2 electrodes are used for power supply / only 1 heating circuit loop). Points B and C are connected to the power supply, and point A is not connected to the power supply. Because the first heating part 101 and the second heating part 102 are closer in the upper part, the heating power density of the pre-baked part 02 is higher than that of the lower part. Therefore, the pre-baked part 02 can be quickly baked, and aerosol can be quickly generated in the pre-baked part 02.

[0119] Please refer to Figure 13 , Figure 13 is a schematic structural diagram of the heating element 10 in the sixth embodiment of the present application.

[0120] In the sixth embodiment, the heating element 10 includes a first heating part 101 and a second heating part 102. The second heating part 102 is located on the side of the first heating part 101 away from the pre-baked part 02. The first heating part 101 and the second heating part 102 are connected. The resistance of the second heating part 102 is less than the resistance of the first heating part 101. The first heating part 101 is used to heat the pre-baked part 02.

[0121] By adopting the above scheme, before the power component drives the connecting member 20 and the aerosol generating substrate 00 to rotate a full circle together around the axis L of the aerosol generating substrate 00, the power density of the first heating part 101 can be made larger, so that the baking degree of the pre-baked part 02 is greater than the baking degree of other parts of the aerosol generating substrate 00, and thus the pre-baked part 02 can generate aerosol more quickly.

[0122] Among them, the cross-sectional area of the first heating part 101 is smaller than that of the second heating part 102, so that the resistance of the second heating part 102 is smaller than that of the first heating part 101.

[0123] In the sixth embodiment, the two ends of the first heating part 101 respectively have an end point A and an end point C, one end of the second heating part 102 has an end point B, the other end of the second heating part 102 is connected to the end point C, and the length direction of the second heating part 102 forms an angle θ with the axis L direction of the aerosol generating matrix 00, and θ can be 0°.

[0124] It should be noted that in the sixth embodiment, the heating element 10 is a single-segment heating both in the preheating stage and the non-preheating stage, that is, points A and B are connected to the power supply.

[0125] Please refer to Figure 14 , Figure 14 which is a schematic structural diagram of the heating element 10 in the seventh embodiment of the present application.

[0126] In the seventh embodiment, the second heating part 102 includes a first part 1021 and a second part 1022 connected in parallel.

[0127] With such a setting, the resistance of the second heating part 102 can be made smaller than that of the first heating part 101, so that the power density of the first heating part 101 can be greater.

[0128] It can be understood that the cross-sectional areas of the first part 1021, the second part 1022 and the first heating part 101 can be approximately equal.

[0129] In the seventh embodiment, the two ends of the second heating part 102 respectively have an end point B and an end point C, one end of the first heating part 101 has an end point A, the other end of the first heating part 101 is connected to the end point C, and the length direction of the first heating part 101 forms an angle θ with the axis L direction of the aerosol generating matrix 00, and θ can be 0°.

[0130] It should be noted that in the seventh embodiment, the heating element 10 is a single-segment heating (points A and B are connected to the power supply) both in the preheating stage and the non-preheating stage. Since the first part 1021 and the second part 1022 of the second heating part 102 in the lower part are connected in parallel, its resistance is small and the corresponding power density is small. Therefore, the power density of the first heating part 101 in the upper part is greater, and the rapid generation of aerosol can be realized by quickly baking the pre-baking part 02 in the upper half section.

[0131] Please refer to Figures 15 to 18 , Figure 15 which is a schematic structural diagram of the aerosol generating device in the eighth embodiment of the present application, Figure 16 isFigure 15 Schematic structural diagram of the heating element 10 in the aerosol generating device shown Figure 17 is Figure 16 Schematic diagram of the projected area swept by the heating element 10 shown when preheating and baking different parts of the aerosol generating substrate 00 Figure 18 is Figure 16 Schematic diagram of the projected area swept by the heating element 10 shown when completely baking different parts of the aerosol generating substrate 00

[0132] In the eighth embodiment, the heating element 10 includes a first heating wire 11 and a second heating wire 12. The second heating wire 12 is located at one end of the first heating wire 11 close to the pre-baking part 02, and the second heating wire 12 is used to heat the pre-baking part 02

[0133] By adopting the above scheme, the pre-baking part 02 can be heated by the second heating wire 12, so that the pre-baking part 02 can quickly generate aerosol

[0134] Wherein, the length direction of the first heating wire 11 is parallel to the axis L direction of the aerosol generating substrate 00, and the length direction of the second heating wire 12 is arranged at an angle with the axis L direction of the aerosol generating substrate 00

[0135] By adopting the above scheme, before the power component drives the connecting member 20 and the aerosol generating substrate 00 to rotate one full circle around the axis L of the aerosol generating substrate 00, the baking degree of the pre-baking part 02 by the second heating wire 12 can be made greater than the baking degree of other parts of the aerosol generating substrate 00 by the first heating wire 11, so that the pre-baking part 02 can generate aerosol more quickly

[0136] It should be noted that the pre-baking part 02 can be located in the upper section of the aerosol generating substrate 00. The first heating wire 11 and the second heating wire 12 can be two separately independently controlled heating circuit loops and can be independently energized for heating

[0137] In the eighth embodiment, the two ends of the first heating wire 11 respectively have an end point C and an end point B. One end of the second heating wire 12 has an end point A, and the other end is connected to the end point B. The length direction of the second heating wire 12 forms an angle θ with the axis L direction of the aerosol generating substrate 00. The first heating wire 11 and the second heating wire 12 are both independently heated. Only the AB section is energized for heating in the preheating stage, and the AB section and the BC section are independently heated or heated simultaneously in the non-preheating stage

[0138] Please refer specifically to Figure 17, the rectangle UVYZ is the circumferential development view of the aerosol - generating substrate 00. During the pre - heating stage of the aerosol - generating substrate 00, the projection area AA’B’C’CB swept by the first heating wire 11 and the second heating wire 12 on the circumferentially - developed rectangle UVYZ of the aerosol - generating substrate 00 is close to about 2 / 5 - 2 / 3 of the area of the rectangle UVYZ. When the first heating wire 11 and the second heating wire 12 are energized and heated during the pre - heating stage, the average power density of the area AA’B’B is 1 / cosθ times (about 1.3 - 2 times) that of the area BB’C’C. The pre - baked part 02 (upper section) of the aerosol - generating substrate 00 is baked more severely than other parts (lower section) of the aerosol - generating substrate 00, and the rapidly - formed aerosol can be provided by relying on the pre - baked part 02 of the aerosol - generating substrate 00.

[0139] Please refer specifically to Figure 18 , after the end of the pre - heating stage, vibration or light can be set to indicate the completion of the pre - heating stage. At this time, the rotation of the aerosol - generating substrate 00 is no longer limited within the projection area AA’B’C’CB, so that the aerosol - generating substrate 00 completes at least one full rotation within one complete heating cycle (it can be 1 rotation, or 2 rotations or more. After completing 1 rotation, it can rotate in the reverse or the same direction continuously), so that the projection area swept by the first heating wire 11 and the second heating wire 12 on the circumferentially - developed rectangle UVYZ of the aerosol - generating substrate 00 can achieve circumferential full coverage, to ensure that the aerosol - generating substrate 00 is fully and evenly baked along the circumference (the aerosol - generating substrate 00 can be partially blank along the height direction, that is, not scanned and directly baked by the first heating wire 11 and the second heating wire 12).

[0140] It should be noted that the pre - baking of the upper - section pre - baked part 02 of the aerosol - generating substrate 00 during the pre - heating stage can be achieved by switching the energized heating circuit, quickly generating aerosol (energizing the heating circuit located in the upper section of the aerosol - generating substrate 00 during the pre - heating stage), and at the same time, almost the same energy accumulation supply can be achieved for the upper and lower sections of the aerosol - generating substrate 00 within the heating cycle, with uniform and balanced baking. After the end of the pre - heating stage, the power supply to the heating circuit of the upper section of the aerosol - generating substrate 00 can be reduced, and the power supply to the heating circuit of the lower section of the aerosol - generating substrate 00 can be increased.

[0141] Please refer to Figure 19 , Figure 19 is the structural schematic diagram of the heating element 10 in the ninth embodiment of the present application.

[0142] In the ninth embodiment, the length direction of the first heating wire 11 is arranged at an angle with respect to the axis L direction of the aerosol generating substrate 00. The first heating wire 11 has opposite first end 111 and second end 112. The second heating wire 12 has opposite third end 121 and fourth end 122. The second end 112 and the third end 121 are arranged at intervals in the circumferential direction of the aerosol generating substrate 00 and are also arranged at intervals in the axis L direction of the aerosol generating substrate 00. Both the first end 111 and the fourth end 122 extend towards the pre-baking part 02, and the distance between the first end 111 and the fourth end 122 in the circumferential direction of the aerosol generating substrate 00 is smaller than the distance between the second end 112 and the third end 121 in the circumferential direction of the aerosol generating substrate 00.

[0143] By adopting the above scheme, before the power member drives the connecting member 20 and the aerosol generating substrate 00 to rotate one full circle around the axis L of the aerosol generating substrate 00, only the second heating wire 12 can heat the pre-baking part 02 or the second end 112 and the third end 121 can jointly heat the pre-baking part 02, so that the baking degree of the pre-baking part 02 is greater than that of other parts of the aerosol generating substrate 00, and thus the pre-baking part 02 can generate aerosol more quickly.

[0144] It should be noted that in the ninth embodiment, heat is generated during the AB section (or the BAC section) of the preheating stage, and only the AC section generates heat during the non-preheating stage. Quick generation of aerosol can be achieved by quickly baking the upper half of the pre-baking part 02.

[0145] Please refer to Figure 20 , Figure 20 which is a schematic structural diagram of the heating element 10 in the tenth embodiment of the present application.

[0146] In the tenth embodiment, the length direction of the second heating wire 12 is perpendicular to the axis L direction of the aerosol generating substrate 00.

[0147] By adopting the above scheme, before the power member drives the connecting member 20 and the aerosol generating substrate 00 to rotate one full circle around the axis L of the aerosol generating substrate 00, the second heating wire 12 can heat the pre-baking part 02, so that the baking degree of the pre-baking part 02 is greater than that of other parts of the aerosol generating substrate 00, and thus the pre-baking part 02 can generate aerosol more quickly.

[0148] Wherein, the length direction of the first heating wire 11 is arranged at an angle with respect to the axis L direction of the aerosol generating substrate 00. Or, the length direction of the first heating wire 11 is parallel to the axis L direction of the aerosol generating substrate 00.

[0149] In the tenth embodiment, the two ends of the second heating wire 12 respectively have an end point A and an end point B, one end of the first heating wire 11 has an end point C, and the other end is connected to the end point B. The length direction of the first heating wire 11 forms an angle θ1 with the length direction of the second heating wire 12, and the length direction of the first heating wire 11 forms an angle θ with the axis L direction of the aerosol-forming substrate 00, and θ can be 0°.

[0150] It should be noted that, in the tenth embodiment, during the preheating stage, the AB section generates heat (or the ABC broken line section generates heat), and during the non-preheating stage, only the BC section generates heat. The rapid generation of aerosol can be achieved by quickly baking the upper half of the pre-baking part 02, and during the non-preheating stage, the entire aerosol-forming substrate 00 can be baked thoroughly and evenly.

[0151] Please refer to Figure 21 , Figure 21 which is a schematic structural diagram of the heating element 10 in the eleventh embodiment of the present application.

[0152] In the eleventh embodiment, one end of the first heating wire 11 close to the pre-baking part 02 is arranged in parallel and at intervals with the second heating wire 12, and the length of the first heating wire 11 is greater than the length of the second heating wire 12.

[0153] By adopting the above scheme, before the power component drives the connecting member 20 and the aerosol-forming substrate 00 to rotate one full circle around the axis L of the aerosol-forming substrate 00, the second heating wire 12 can heat the pre-baking part 02, so that the baking degree of the pre-baking part 02 can be greater than that of other parts of the aerosol-forming substrate 00, thereby enabling the pre-baking part 02 to generate aerosol more quickly.

[0154] Among them, the length direction of the first heating wire 11 is arranged at an angle with the axis L direction of the aerosol-forming substrate 00. Alternatively, the length direction of the first heating wire 11 is parallel to the axis L direction of the aerosol-forming substrate 00.

[0155] In the eleventh embodiment, the two ends of the first heating wire 11 respectively have an end point C and an end point D, the two ends of the second heating wire 12 respectively have an end point A and an end point B, and the length direction of the first heating wire 11 forms an angle θ with the axis L direction of the aerosol-forming substrate 00, and θ can be 0°.

[0156] It should be noted that, in the eleventh embodiment, during the preheating stage, the AB section generates heat (or the AB section and the CD section generate heat simultaneously), and during the non-preheating stage, only the CD section generates heat. The rapid generation of aerosol can be achieved by quickly baking the upper half of the pre-baking part 02, and during the non-preheating stage, the entire aerosol-forming substrate 00 can be baked thoroughly and evenly.

[0157] Please refer to Figure 22 , Figure 22It is a schematic structural diagram of the heating element 10 in the twelfth embodiment of the present application.

[0158] In the eleventh embodiment, the heating element 10 includes a first heating wire 11 and a second heating wire 12. The first heating wire 11 has opposite first end 111 and second end 112 and a connecting portion 113 located between the first end 111 and the second end 112. The second end 112 faces the pre-baking portion 02. The second heating wire 12 has opposite third end 121 and fourth end 122. The fourth end 122 is connected to the connecting portion 113. The third end 121 extends in the direction close to the pre-baking portion 02, and the third end 121 and the first end 111 are arranged at intervals along the circumferential direction of the aerosol generating substrate 00.

[0159] By adopting the above solution, before the power member drives the connecting member 20 and the aerosol generating substrate 00 to rotate one full circle around the axis L of the aerosol generating substrate 00, the second heating wire 12 can be used to heat the pre-baking portion 02, so that the baking degree of the pre-baking portion 02 is greater than that of other parts of the aerosol generating substrate 00, thereby enabling the pre-baking portion 02 to generate aerosol more quickly.

[0160] Wherein, the length direction of the first heating wire 11 is arranged at an angle with the axis L direction of the aerosol generating substrate 00. Alternatively, the length direction of the first heating wire 11 is parallel to the axis L direction of the aerosol generating substrate 00.

[0161] In the twelfth embodiment, the two ends of the first heating wire 11 respectively have an end point A and an end point C. One end of the second heating wire 12 has an end point B, and the other end is connected to the connecting portion 113 of the first heating wire 11. The length direction of the first heating wire 11 forms an angle θ with the axis L direction of the aerosol generating substrate 00, and θ can be 0°.

[0162] It should be noted that in the twelfth embodiment, the AB section of the heating element generates heat during the preheating stage (or the AC section and the BC section generate heat simultaneously), and only the AC section generates heat during the non-preheating stage. The aerosol can be quickly generated by quickly baking the upper half of the pre-baking portion 02, and the entire aerosol generating substrate 00 can be baked thoroughly and evenly during the non-preheating stage.

[0163] Please refer to Figures 1 to 22 , on the second aspect, the embodiment of the present application also provides a control method for the above aerosol generating device, including:

[0164] Obtain the environmental parameters of the part of the aerosol generating device for discharging aerosol, where the environmental parameters include temperature and / or pressure; if the change amount of the environmental parameters is greater than a first preset value, use a power component to drive the connecting member 20 and the aerosol generating substrate 00 to rotate together around the axis of the aerosol generating substrate 00, and use the heating element 10 to bake different parts of the aerosol generating substrate 00.

[0165] Among them, the part of the aerosol generating device for discharging aerosol can be an exhaust hole. The temperature and pressure inside the air outlet can be correspondingly detected by a temperature sensor, a pressure sensor, etc.

[0166] By adopting the above solution, it is possible to determine whether it is necessary to control the power component to drive the connecting member 20 and the aerosol generating substrate 00 to rotate together around the axis L of the aerosol generating substrate 00 through the change of the environmental parameters, so that it is possible to judge and ensure that the rotation behavior only occurs at an appropriate time by monitoring the user's behavior, and avoid breaking the aerosol generating substrate 00.

[0167] In another embodiment, a control method for an aerosol generating device includes:

[0168] Obtain the use distance between the user and the aerosol generating substrate 00. If the use distance is greater than a second preset value, use a power component to drive the connecting member 20 and the aerosol generating substrate 00 to rotate together around the axis of the aerosol generating substrate 00, and use the heating element 10 to bake different parts of the aerosol generating substrate 00.

[0169] Among them, the use distance between the user and the aerosol generating substrate 00 can be detected by a Hall sensor, etc.

[0170] By adopting the above solution, it is possible to determine whether it is necessary to control the power component to drive the connecting member 20 and the aerosol generating substrate 00 to rotate together around the axis L of the aerosol generating substrate 00 through the change of the use distance between the user and the aerosol generating substrate 00, so that it is possible to judge and ensure that the rotation behavior only occurs at an appropriate time by monitoring the user's behavior, and avoid breaking the aerosol generating substrate 00.

[0171] It can be understood that when the user approaches the aerosol generating device, for example, when the distance between the user and the aerosol generating substrate 00 is small (such as 0, that is, in contact), the Hall sensor detects a signal. At this time, it is not necessary to drive the connecting member 20 and the aerosol generating substrate 00 to rotate together around the axis L of the aerosol generating substrate 00 to avoid breaking the aerosol generating substrate 00. When the distance between the user and the aerosol generating substrate 00 is large, then drive the connecting member 20 and the aerosol generating substrate 00 to rotate together around the axis L of the aerosol generating substrate 00.

[0172] In yet another embodiment, a control method for an aerosol generating device includes:

[0173] Obtain a circuit signal corresponding to the heating element 10, where the circuit signal includes at least one of voltage, current, power, and load resistance; if the change amount of the circuit signal is greater than a third preset value, use a power component to drive the connecting member 20 and the aerosol generating substrate 00 to rotate together around the axis of the aerosol generating substrate 00, and use the heating element 10 to bake different parts of the aerosol generating substrate 00.

[0174] Among them, the circuit signal corresponding to the heating element 10 can be obtained through a controller of the aerosol generating device, etc.

[0175] By adopting the above solution, it is possible to determine whether it is necessary to control the power component to drive the connecting member 20 and the aerosol generating substrate 00 to rotate together around the axis L of the aerosol generating substrate 00 according to the change of the circuit signal corresponding to the heating element 10, so that it is possible to judge and ensure that the rotation behavior only occurs at an appropriate time by monitoring the user's behavior, and avoid breaking the aerosol generating substrate 00.

[0176] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application, and should all be included in the protection scope of the present application.
