Description

Heater and aerosol generating device

Technical Field

The present application relates to the field of atomization technology, and in particular to a heater and an aerosol generating device.

Background Art

The aerosol generating device generates aerosol by heating the aerosol generating substrate through the heating element. However, the relative position between the existing heating element and the aerosol generating substrate is fixed, and the heating element heats the entire aerosol generating substrate as a whole. As the heating time accumulates, the smoke-generating ability of the aerosol generating substrate gradually decreases, and the aerosol release amount gradually decreases, resulting in a large difference in taste between different numbers of puffs before and after puffing, and poor consistency in aerosol release. In addition, the heating element repeatedly heats the part of the aerosol generating substrate close to it, which easily causes a burnt smell in that part, while the temperature of other parts far away from that part may not generate smoke sufficiently due to insufficient baking temperature.

DETAILED DESCRIPTION

It should be noted that the various embodiments/implementations provided in this application can be combined with each other without causing any contradiction. The detailed description in the specific implementation mode should be understood as an explanation of the purpose of this application and should not be regarded as an improper limitation on this application.

In the description of the present application, the term "length direction" orientation is based on the orientation shown in Figure 2. It should be understood that these orientation terms are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present application.

Please refer to FIG. 1 to FIG. 3 , an embodiment of the present application provides an aerosol generating device, and the aerosol generating device includes an aerosol generating article 200 and a heater in any one embodiment of the present application.

Referring to Figures 4 and 5, the aerosol generating article 200 includes an aerosol generating substrate 210. The aerosol generating substrate 210 is used to be heated to generate an aerosol. Exemplarily, the aerosol generating substrate 210 can be suitable for generating an aerosol in a heating-not-burning manner. That is, the aerosol generating substrate 210 is heated to below the ignition point to generate an aerosol. The aerosol generating substrate 210 does not burn during the process of generating the aerosol. The aerosol generating article 200 is used for the user to inhale the aerosol generated by the aerosol generating substrate 210.

The aerosol-generating substrate 210 may be in a solid state.

It should be noted that in the embodiments of the present application, the length direction does not specifically refer to the direction in which the outer contour of the aerosol generating substrate 210 is the longest. Specifically, the arrangement direction of the nozzle segment 220 and the aerosol generating substrate 210 is consistent with the length direction; for example, the direction in which the aerosol generating product 200 is plugged into the bracket 1 and the direction in which the aerosol generating product 200 is removed from the bracket 1 are both parallel to the length direction. The length of the aerosol generating substrate 210 along the length direction may be longer, shorter, or the same as the length in other directions.

For example, when the appearance of the aerosol generating substrate 210 is cylindrical, the length direction is the axial direction of the aerosol generating substrate 210. It should be noted that even when the axial length of the aerosol generating substrate 210 is less than its diameter, the length direction of the aerosol generating substrate 210 is still the axial direction. For another example, when the appearance of the aerosol generating substrate 210 is a rectangular parallelepiped, the length direction is still the direction defined above, that is, the arrangement direction of the mouthpiece segment 220 and the aerosol generating substrate 210, or the direction of taking and placing the aerosol generating article 200. The length direction of the aerosol generating substrate 210 can be any direction of the length, width, and height of the rectangular parallelepiped.

When the aerosol generating matrix 210 is used alone, that is, not combined with the mouthpiece segment 220, the length direction is the perpendicular direction of the distance between the two ends of the aerosol generating matrix 210. For example, when the aerosol generating matrix 210 is a cylinder, the length direction is the perpendicular direction of the distance between the two end surfaces. For example, when the aerosol generating matrix 210 is a column with a cross-section in a triangular, polygonal, oblong, elliptical or other shape, the length direction is the axial direction. When the aerosol generating matrix 210 is a rectangular parallelepiped, the length direction of the aerosol generating matrix 210 can be any direction of the length, width, or height of the rectangular parallelepiped.

In some embodiments, see Fig. 6 , the aerosol generating substrate 210 may be substantially columnar, that is, the aerosol generating substrate 210 is substantially strip-shaped, and the length of the aerosol generating substrate 210 is greater than the maximum distance between two points on its cross section.

Exemplarily, in a cross section perpendicular to the length direction of the aerosol generating substrate 210, the cross-sectional shape of the aerosol generating substrate 210 includes, but is not limited to, a circle, an ellipse, a racetrack, or a polygon, etc. The cross-sectional shape of the aerosol generating substrate 210 is the above-mentioned regular shape, the product consistency is good, and it is convenient to monitor the product quality. The embodiment of the present application takes the cross-sectional shape of the aerosol generating substrate 210 as a circle as an example for illustration, please refer to Figure 6, that is, the aerosol generating substrate 210 is a cylinder. The dimension of the aerosol generating substrate 210 in the length direction is greater than the maximum distance between two points on its cross section, such as the diameter.

The specific components of the aerosol generating matrix 210 are not limited herein. For example, in one embodiment, the aerosol generating product 200 may include plant components, auxiliary components, smoke generating agent components, adhesive components, and the like.

In one embodiment, the plant component is one or more combinations of powders formed by crushing tobacco raw materials, tobacco leaf fragments, tobacco stems, tobacco dust, aromatic plants, etc. The plant component is used to generate an aerosol containing alkaloids when heated.

In one embodiment, the auxiliary agent component can be one or more combinations of inorganic fillers, lubricants, and emulsifiers. Among them, the inorganic filler includes one or more combinations of heavy calcium carbonate, light calcium carbonate, zeolite, attapulgite, talc, and diatomaceous earth. The inorganic filler can provide a skeleton support for the plant component, and the inorganic filler also has micropores, which can increase the porosity of the wall material after the plant component is formed, thereby increasing the aerosol release rate.

The lubricant includes one or more combinations of candelilla wax, carnauba wax, shellac, sunflower wax, rice bran, beeswax, stearic acid, and palmitic acid. The lubricant can increase the fluidity of the particles, reduce the friction between the particles, make the overall density of the particle distribution more uniform, and also reduce the pressure required for mold molding and reduce the wear of the mold.

The emulsifier includes one or more combinations of polyglycerol fatty acid ester, Tween-80, and polyvinyl alcohol. The emulsifier can slow down the loss of flavor substances during storage to a certain extent, increase the stability of flavor substances, and improve the sensory quality of the product.

The function of the smoke-generating agent component is to generate a large amount of steam when heated, thereby increasing the amount of smoke. In one embodiment, the smoke-generating agent may include, for example: a monohydric alcohol (such as menthol); a polyhydric alcohol (such as propylene glycol, triethylene glycol, 1,3-butylene glycol and glycerol); an ester of a polyhydric alcohol (such as monoacetin, diacetin or triacetin); a monocarboxylic acid; a polycarboxylic acid (such as lauric acid, myristic acid) or an aliphatic ester of a polycarboxylic acid (such as dimethyl dodecanedioate, dimethyl tetradecanedioate, erythritol, 1,3-butylene glycol, tetraethylene glycol, triethyl citrate, propylene carbonate, ethyl laurate, Triactin, meso-erythritol, diacetin mixture, diethyl suberate, triethyl citrate, benzyl benzoate, benzyl phenylacetate, ethyl vanillate, tributyrin, lauryl acetate) or one or more combinations thereof.

In one embodiment, the adhesive component is a natural plant-extracted, non-ionized modified viscous polysaccharide, including one or more combinations of tamarind polysaccharide, pullulan, seaweed polysaccharide, locust bean gum, guar gum, and xyloglucan. The adhesive is used to bond the particles together, making them less likely to loosen. In addition, it improves the water resistance of the aerosol-generating product 200, is harmless to the human body, and has a certain health-care effect.

In one embodiment, the aerosol generating matrix 210 is an integrally formed structure. For example, the aerosol generating matrix 210 can be an integral structure formed by processes such as injection molding, compression molding or extrusion. Extrusion molding refers to a processing method in which a raw material mixture is added to an extruder, and the raw material mixture is plasticized by heat and pushed forward by the screw through the action between the extruder barrel and the screw, and continuously passes through the die to form various cross-section products or semi-finished products. The aerosol generating matrix 210 formed by extrusion molding is in the shape of strips. In this way, after the aerosol generating matrix 210 is heated and sucked or stops being heated, it is an integral medium, and it is not easy to disintegrate and fall off, which solves the problems of the three types of aerosol generating matrices 210 in the prior art, such as flake loosening, filamentous components, granular components falling off, and difficult cleaning.

In one embodiment, referring to FIG. 5 and FIG. 6 , the aerosol generating substrate 210 has an air channel 210 a, and the air channel 210 a runs through at least one end of the aerosol generating substrate 210 along the length direction. The air channel 210 a can be used to collect and circulate aerosol. The air channel 210 a can increase the porosity of the aerosol generating substrate 210, and prevent the aerosol from being intercepted by the unheated area and unable to be inhaled by the user, which can not only improve the flow resistance of the aerosol, thereby improving the suction resistance, but also improve the heating efficiency, thereby improving the release efficiency of the aerosol.

Exemplarily, in one embodiment, the airway 210a runs through one end of the aerosol generating matrix 210 along the length direction, and the other end of the airway 210a is closed. In this way, the airway 210a can not only play a role in regulating the heating rate of the aerosol generating matrix 210 during the heating process, but also play a role in temporarily storing aerosols and accelerating the precipitation of aerosols. In the non-pumping state, the aerosol will be released into the airway 210a for storage. During the suction, due to the high airflow velocity near the lip side of the aerosol generating matrix 210, that is, the low air pressure, the aerosol stored in the airway 210a will be precipitated to the user for suction. Because the user will have free time, that is, rest time, during the suction process, during this free time, the conditions are provided for the aerosol to be supplemented into the airway 210a. When the free time is too long, the aerosol in the airway 210a will overflow into the aerosol generating matrix 210, ensuring that the aerosol vector in the airway 210a is uniform, thereby ensuring the consistency of the user's suction.

It should be noted that the distal lip side refers to the side away from the user's lips, and the proximal lip side is opposite to the distal lip side.

In some embodiments, referring to FIG. 5 and FIG. 6 , the air passage 210a runs through opposite ends of the aerosol generating substrate 210 along the length direction. The airflow can flow from one end of the aerosol generating substrate 210 to the other end of the aerosol generating substrate 210. In this way, the outside air can carry the aerosol through the aerosol generating substrate 210 more smoothly and be inhaled by the user, which is not only more conducive to the precipitation of the aerosol, but also can reduce the suction resistance during the suction process.

In one embodiment, referring to Figures 5 and 6, the air channel 210a includes pores, which are disposed inside the aerosol generating substrate 210. The pores are surrounded by the outer peripheral surface of the aerosol generating substrate 210. The pores can collect aerosols and play a good guiding role.

Exemplarily, referring to FIG. 5 and FIG. 6 , the air holes are through holes penetrating the aerosol generating substrate 210 at opposite ends along the length direction.

In one embodiment, the airway 210a includes a groove, and the groove is arranged on the peripheral surface of the aerosol generating matrix 210. Specifically, the groove has a gap that opens outward. Exemplarily, a portion of the circumferential surface of the aerosol generating matrix 210 is recessed to form a groove, which is equivalent to being able to see the groove on the peripheral surface of the aerosol generating matrix 210. On the one hand, the groove can increase the surface area of the aerosol generating matrix 210, increase the heat conduction efficiency, and be more conducive to the extraction of effective ingredients. Exemplarily, if the heating element 2 is on the periphery of the aerosol generating matrix 210, the overall heating rate of the aerosol generating matrix 210 can also be adjusted in this way to enhance the user experience. On the other hand, exemplarily, since the periphery of the aerosol generating matrix 210 is wrapped with the outer wrapping layer 230, the outer wrapping layer 230 can close the gap of the groove. The outer wrapping layer 230 cooperates with the groove to form a channel that is open only at at least one end along the length direction of the aerosol generating matrix 210, thereby playing a guiding role in limiting the flow of aerosol and external air along the length direction, which can increase the amount of air entering and improve the aerosol extraction efficiency.

The number of the air channel 210a is not limited. For example, referring to FIG5 and FIG6 , there may be one air channel 210a. In other embodiments, there may be more than one air channel 210a.

In some embodiments, all of the air channels 210a pass through the same end of the aerosol generating substrate 210 along the length direction, and the other end is a closed end, that is, all of the air holes and/or grooves open toward the same end.

In other embodiments, a portion of the air passage 210a runs through one end of the aerosol generating substrate 210 along the length direction, and another portion of the air passage 210a runs through the other end of the aerosol generating substrate 210 along the length direction.

In some other embodiments, all the air passages 210a penetrate both ends of the aerosol generating substrate 210 along the length direction. The airflow may flow from one end of the aerosol generating substrate 210 along the length direction to the other end of the aerosol generating substrate 210 along the length direction through the air passages 210a.

In some embodiments, please refer to Figures 3 and 5, the aerosol generating product 200 includes a mouthpiece segment 220 and a front functional segment 240, and the mouthpiece segment 220 and the front functional segment 240 are respectively arranged at two opposite ends of the aerosol generating substrate 210 along the length direction. Exemplarily, the mouthpiece segment 220 is arranged at one end of the aerosol generating substrate 210 away from the bracket 1 along the length direction. The user can inhale the aerosol by holding the mouthpiece segment 220 in the mouth. The front functional segment 240 is used to absorb the liquid formed after the aerosol condenses. The front functional segment 240 can also provide suction resistance to enhance the suction experience.

In some embodiments, referring to FIG. 3 and FIG. 5 , the aerosol generating article 200 includes an outer wrapping layer 230 , which wraps around the periphery of the mouthpiece segment 220 , the periphery of the aerosol generating matrix 210 , and the periphery of the front functional segment 240 .

In some embodiments, the mouthpiece section 220 includes a filter section, which is used to filter the aerosol generated by the aerosol generating substrate 210. The aerosol generated by the aerosol generating substrate 210 is transported to the filter section through the airway 210a under the action of the negative suction pressure.

In some embodiments, the nozzle section 220 may only be provided with a filtering section.

In some other embodiments, the mouthpiece section 220 further includes a cooling section, which is located between the filtering section and the aerosol generating matrix 210. The cooling section is used to cool the aerosol before the filtering section filters the aerosol. The cooling section can improve the "hot mouth" phenomenon when the user inhales the aerosol.

The outer wrapping layer 230 includes but is not limited to one or more combinations of materials such as fiber paper, metal foil, metal foil composite fiber paper, polyethylene composite fiber paper, PE (Polyethylene), PBAT (Polybutylene Adipate Terephthalate), etc.

The cooling materials used in the cooling section include but are not limited to one or more combinations of PE (polyethylene), PLA (Polylactic Acid), PBAT (Polybutylene Adipate Terephthalate), PP (Polypropylene), acetate fiber, acrylic fiber and the like.

The filter materials used in the filter section include but are not limited to one or more combinations of PE (polyethylene), PLA (Polylactic Acid), PBAT (Polybutylene Adipate Terephthalate), PP (Polypropylene), acetate fiber, acrylic fiber and the like.

The materials of the cooling section and the filtering section can be the same or different.

For example, referring to FIG. 3 and FIG. 5 , the front functional section 240 may have a structure with multiple holes. The holes of the front functional section 240 may store liquid formed after aerosol condensation. The liquid absorbing material that may be used in the front functional section 240 includes, but is not limited to, polyester fiber, synthetic fiber, non-woven fabric, activated carbon and other cotton fiber materials.

The heater provided in the embodiment of the present application can be used in an aerosol generating device. Referring to FIG. 7 to FIG. 9 , the heater includes a bracket 1 and a heating element 2 .

3 , the support 1 is used to place the aerosol generating article 200. The support 1 provides a mounting position for the aerosol generating article 200.

1 and 3 , the heating element 2 is located outside and/or inside the aerosol generating substrate 210 of the aerosol generating article 200. In the circumferential direction of the aerosol generating substrate 210, the circumference of the heating element 2 is smaller than the circumference of the aerosol generating substrate 210, and the heating element 2 and the support 1 can rotate relative to each other so that the heating element 2 heats the aerosol generating substrate 210 in different zones.

The support 1 can drive the aerosol generating article 200 to rotate synchronously or remain stationary. That is, the heating element 2 can rotate relative to the aerosol generating substrate 210 to selectively heat different parts of the aerosol generating substrate 210. For example, the aerosol generating substrate 210 is divided into multiple regions along the circumference, and the circumference of each region is the same as the circumference of the heating element 2. After the heating element 2 fully bakes one of the regions so that the aerosol is released, the heating element 2 and the aerosol generating substrate 210 rotate relative to each other, so that the heating element 2 heats another region of the aerosol generating substrate 210 to release the aerosol, until all regions of the aerosol generating substrate 210 are fully baked.

Exemplarily, in one embodiment, please refer to FIG. 1 and FIG. 3 , the heating element 2 is located at the periphery of the aerosol generating substrate 210 .

In another embodiment, a cavity is formed inside the aerosol generating substrate 210, and the heating element 2 is located in the cavity. Further, in the circumferential direction of the aerosol generating substrate 210, the circumference of the heating element 2 may be smaller than the circumference of the cavity.

The heater provided in the embodiment of the present application selectively heats different parts of the aerosol generating matrix 210 through the heating element 2, so that different parts of the aerosol generating matrix 210 are selected to release aerosol respectively. This can not only avoid the problem of repeatedly heating the entire aerosol generating matrix 210 to produce burnt odors and other odors, making the taste difference in different puffing periods smaller, but also improve the consistency of aerosol release of the aerosol generating matrix 210 and improve the consistency of the puffing taste.

In some embodiments, it may be determined that the region of the aerosol generating substrate 210 is replaced when the number of puffs in the region of the currently heated aerosol generating substrate 210 reaches a set number of times or the total puffing time reaches a set time.

In one embodiment, referring to Figures 3 and 9, the support 1 is located on one side of the length direction of the aerosol generating product 200, and one end of the aerosol generating product 200 along the length direction is connected to the support 1. With such a design, the support 1 does not need to penetrate the outer wrapping layer 230 to connect with the aerosol generating product 200, which can avoid the support 1 from damaging the outer wrapping layer 230 as much as possible, and can also avoid the support 1 from interfering with the relative rotation of the heating element 2 and the aerosol generating substrate 210.

Exemplarily, in one embodiment, please refer to FIG. 3 , an end of the aerosol generating article 200 away from the mouthpiece section 220 along the length direction is connected to the bracket 1 .

In one embodiment, referring to Fig. 3, the heater includes a mounting base 4, the bracket 1 and the mounting base 4 are both located on the same side of the aerosol generating article 200 along the length direction, and one end of the heating element 2 along the length direction of the aerosol generating article 200 is connected to the mounting base 4. Such a design can prevent the mounting base 4 from interfering with the relative rotation of the heating element 2 and the aerosol generating substrate 210.

In one embodiment, referring to Figures 3 and 9, the mounting base 4 can be used to fix the heating element 2 so that the heating element 2 remains stationary. In other words, the heating element 2 does not move, and the bracket 1 drives the aerosol generating article 200 to rotate.

Exemplarily, in one embodiment, the aerosol generating device includes a housing, and the heater is disposed in the housing. The mounting base 4 may be connected to the housing. In other embodiments, the mounting base 4 may also be connected to a fixing frame of the aerosol generating device, and the fixing frame is located in the housing.

In one embodiment, referring to Fig. 3, Fig. 8 and Fig. 9, the mounting seat 4 includes a seat body portion 41 and a rod body portion 42, the seat body portion 41 is located on the side of the bracket 1 away from the aerosol generating product 200, one end of the rod body portion 42 is connected to the heating element 2, and the other end of the rod body portion 42 is connected to the seat body portion 41. Exemplarily, the seat body portion 41 can be connected to the housing or the fixing frame. On the one hand, the mounting seat 4 can avoid the bracket 1 and the aerosol generating product 200. On the other hand, the mounting seat 4 has a simple structure and a relatively light overall mass.

For example, in one embodiment, please refer to Figures 3, 8 and 9, the mounting base 4 is an integrally formed structure. In this way, not only can the assembly steps be saved, but the structural strength of the mounting base 4 is also better.

For example, in one embodiment, referring to Figures 3, 8 and 9, the heating element 2 is located at the periphery of the aerosol generating product 200, and the rod body 42 is located at the periphery of the bracket 1. In this way, the bracket 1 is conveniently connected to the aerosol generating product 200, and the heating element 2 will not interfere with the bracket 1 driving the aerosol generating product 200 to rotate.

In one embodiment, please refer to FIG. 3 , FIG. 7 and FIG. 9 , the number of the heating elements 2 is multiple, and the multiple heating elements 2 are arranged at intervals in the circumferential direction around the aerosol generating matrix 210. The multiple heating elements 2 can provide multiple heating forms, for example, only one heating element 2 can be selected to be heated separately. For another example, multiple heating elements 2 can also be selected to be heated synchronously. In this way, not only can aerosols be provided to users at multiple angles, but also aerosols of multiple concentrations can be provided, which is more diverse.

It should be noted that the term "plurality" refers to a number including two or more.

Exemplarily, in one embodiment, referring to FIG. 3 , FIG. 7 and FIG. 9 , there are two heating elements 2 , and the two heating elements 2 are located on a straight line passing through the center of the cross section of the aerosol generating substrate 210 .

The number of rod parts 42 and heating elements 2 is the same. In one embodiment, please refer to Figures 3, 7 and 9. Each heating element 2 corresponds to one rod part 42. In other words, the rod parts 42 are arranged one by one with the heating elements 2. Taking two heating elements 2 as an example, there are also two rod parts 42, and each heating element 2 is connected to one rod part 42.

In some embodiments, all the heating elements 2 are controlled synchronously. That is, all the heating elements 2 start and stop synchronously and/or adjust the heating temperature. In this way, the aerosol release amount can be larger and the taste can be more intense.

Exemplarily, in some embodiments, multiple heating elements 2 are independently controlled. That is, each heating element 2 can be started and stopped and/or the heating temperature can be adjusted independently. On the one hand, the selectivity is better. For example, if the user needs a more concentrated aerosol, two or more heating elements 2 can be turned on at the same time, or even all heating elements 2 can be turned on. On the other hand, it can play a backup role. For example, if one of the heating elements 2 fails, such as being damaged, other heating elements 2 can be turned on.

The power source of the heating element 2 is not limited. For example, in one embodiment, the heating element 2 or the bracket 1 is manually driven, that is, the user's hand drives the heating element 2 to rotate or the bracket 1 to rotate.

In one embodiment, referring to Figures 1, 8 and 9, the heater includes a driving member 3. The driving member 3 is used to provide kinetic energy.

In one embodiment, referring to Figures 3, 8 and 9, the driving member 3 is connected to the bracket 1 to drive the bracket 1 to rotate. In this way, the bracket 1 drives the aerosol generating product 200 to rotate synchronously. For example, after the aerosol in one area of the aerosol generating matrix 210 is released, the driving member 3 can drive the bracket 1 to rotate a set angle, so that the heating element 2 heats another area of the aerosol generating matrix 210 to release the aerosol. With this design, the heating element 2 can remain stationary, avoiding the situation where the external electrical wiring of the heating element 2 is wound and/or misaligned with other components, reducing the difficulty of wiring.

It should be understood that in some embodiments, the driving member 3 may drive the bracket 1 to rotate before the user takes a single puff, and the bracket 1 remains stationary during the user's single puff. In some embodiments, the driving member 3 may drive the bracket 1 to rotate during the user's rest time of taking a puff. In some embodiments, the driving member 3 may also drive the bracket 1 to rotate after the user finishes a single puff.

The driving component 3 includes but is not limited to a motor.

In one embodiment, referring to Figures 3, 8 and 9, the driving member 3 is located on a side of the support 1 away from the aerosol generating article 200, and the support 1 includes a transmission rod 11, and a first end of the transmission rod 11 is connected to the driving member 3. Exemplarily, the first end of the transmission rod 11 is connected to the motor shaft of the motor.

In one embodiment, the second end of the transmission rod 11 is inserted into the aerosol generating article 200. The second end of the transmission rod 11 can be anti-rotationally matched with the aerosol generating article 200. Anti-rotationally matched means that relative rotation cannot occur. In this way, the second end of the transmission rod 11 can drive the aerosol generating article 200 to rotate synchronously, and it is also convenient to replace the aerosol generating article 200.

In one embodiment, the second end of the transmission rod 11 can be inserted into one end of the aerosol generating product 200 along the length direction. When the aerosol generating product 200 needs to be replaced, the old aerosol generating product 200 is pulled out of the second end of the transmission rod 11, and the new aerosol generating product 200 is plugged into the second end of the transmission rod 11. In this way, it is convenient to take the aerosol generating product 200 from the bracket 1, and the heater can be reused.

Exemplarily, in one embodiment, an insertion port 200a is formed at one end of the aerosol generating article 200 along the length direction, and the second end of the transmission rod 11 is inserted into the insertion port 200a. The second end of the transmission rod 11 can be tightly matched with the insertion port 200a. In other words, the surface of the insertion port 200a can be pressed against the circumferential surface of the second end of the transmission rod 11, and the friction between the surface of the insertion port 200a and the circumferential surface of the second end of the transmission rod 11 can prevent the two from rotating relative to each other.

In one embodiment, referring to Figures 3, 8 and 9, the support 1 includes a supporting member 12 for connecting the aerosol generating product 200, and the second end of the transmission rod 11 is connected to the supporting member 12. The supporting member 12 can support the aerosol generating product 200 more stably.

In one embodiment, referring to FIG. 3 , FIG. 8 and FIG. 9 , the support member 12 includes a tray 121 and a pillar 122, the pillar 122 is connected to one side of the tray 121 along the thickness direction, the second end of the transmission rod 11 is connected to the other side of the tray 121 away from the pillar 122, the aerosol generating product 200 is supported on the tray 121, and the pillar 122 is inserted into the aerosol generating product 200. When the aerosol generating product 200 needs to be replaced, the old aerosol generating product 200 is pulled out of the pillar 122, so that the old aerosol generating product 200 is separated from the support member 12, and then the new aerosol generating product 200 is inserted into the pillar 122. In this way, it is convenient to take and place the aerosol generating product 200 from the bracket 1, and the heater can be reused. The contact area between the tray 121 and the aerosol generating product 200 is large, and the aerosol generating product 200 can be supported more stably. The pillar 122 is engaged with the aerosol generating product 200 to prevent rotation. In this way, the support 122 can drive the aerosol generating article 200 to rotate synchronously.

In one embodiment, referring to Figures 3, 8 and 9, one end of the aerosol generating product 200 along the length direction is placed on the tray 121, and the support 122 can be inserted into the one end of the aerosol generating product 200 along the length direction. During the process of assembling the aerosol generating product 200 onto the bracket 1, the tray 121 serves to limit the assembly of the aerosol generating product 200, thereby preventing the aerosol generating product 200 from excessively moving along the length direction.

For example, in one embodiment, referring to Figures 3, 5, 8 and 9, the pillar 122 is inserted into the insertion port 200a of the aerosol generating article 200. The pillar 122 can be tightly fitted or interference fit with the insertion port 200a. In other words, the surface of the insertion port 200a can be pressed against the circumferential surface of the pillar 122, and the friction between the surface of the insertion port 200a and the circumferential surface of the pillar 122 can prevent the two from rotating relative to each other.

For example, in some embodiments, referring to FIG5 , when the aerosol generating article 200 has a front functional section 240, the insertion port 200a may be formed inside the front functional section 240. In other embodiments, when the aerosol generating article 200 does not have a front functional section 240, the insertion port 200a may be formed inside the aerosol generating substrate 210.

In some embodiments, referring to FIG. 3 and FIG. 9 , the support member 12 is formed with an opening groove 12a that opens toward the transmission rod 11, and the second end of the transmission rod 11 is inserted into the opening groove 12a. Specifically, the second end of the transmission rod 11 is inserted into the opening groove 12a through the opening of the opening groove 12a. The opening groove 12a facilitates the positioning and assembly of the transmission rod 11 onto the support member 12.

In some embodiments, referring to FIG3 and FIG9 , the second end of the transmission rod 11 is tightly fitted or interference fit with the opening groove 12 a , so that the transmission rod 11 and the supporting member 12 are fixed to each other.

In some embodiments, referring to FIG. 3 and FIG. 9 , the supporting member 12 includes a boss 123 , which is connected to another side surface of the tray 121 away from the support column 122 along the thickness direction, and the boss 123 is formed with an open slot 12 a .

In one embodiment, the driving member 3 is connected to the heating element 2 to drive the heating element 2 to rotate. In this way, the support 1 and the aerosol generating article 200 remain stationary.

The heating method of the heating element 2 includes, but is not limited to, resistance heating, electromagnetic heating, infrared heating, microwave heating or laser heating.

In one embodiment, referring to FIG. 1 , FIG. 3 and FIG. 8 , the heater includes a coil 5, the heating element 2 is located outside the aerosol generating substrate 210, and the coil 5 is sleeved on the outer periphery of the heating element 2. The coil 5 and the heating element 2 can be electromagnetic heating elements. In other words, the coil 5 can be an electromagnetic coil, and the heating element 2 generates eddy current self-heating in the magnetic field of the coil 5.

In one embodiment, referring to FIG. 1 , FIG. 3 and FIG. 7 , the heater includes a sleeve 6 having a heating cavity 6a, and the aerosol generating substrate 210 and the heating element 2 are both located in the heating cavity 6a. The heating cavity 6a formed by the sleeve 6 accommodates the aerosol generating substrate 210 and the heating element 2 at the same time, so that less heat generated by the heating element 2 is lost to the heating cavity 6a, thereby improving the heating efficiency. In addition, the sleeve 6 may also be formed with a positioning structure for assisting in positioning the aerosol generating product 200, such as abutting the position of the mouthpiece section 220 of the aerosol generating product 200.

Exemplarily, in one embodiment, please refer to FIG1 , the coil 5 is sleeved on the outside of the sleeve 6 . The sleeve 6 can provide a mounting position for the coil 5 .

In one embodiment, referring to Figures 1, 3 and 9, the length of the heating element 2 is not less than the length of the aerosol generating substrate 210. In this way, in the length direction, the heating element 2 can heat all positions of the aerosol generating substrate 210 as much as possible, avoiding the situation where the baking temperature of some positions in the length direction of the aerosol generating substrate 210 is insufficient.

In one embodiment, referring to FIG. 6, FIG. 7 and FIG. 9, the aerosol generating substrate is cylindrical, the outer cross-sectional shape of the aerosol generating substrate 210 is circular, the number of the heating elements is two, and the cross-sectional shape of each heating element 2 is arc-shaped. The outer cross-sectional shape of the aerosol generating substrate 210 is the shape of the outer contour of the cross-sectional shape of the aerosol generating substrate 210. In this way, in the circumferential direction of the aerosol generating substrate 210, the distances between various parts of the heating element 2 and the circumferential surface of the aerosol generating substrate 210 are substantially equal, and the aerosol generating substrate 210 can be evenly heated.

In one embodiment, the aerosol generating device includes a power supply and a controller. The controller is electrically connected to the power supply and the driving member 3 respectively. The power supply provides electrical energy to the driving member 3 and the controller. The controller controls the driving member 3 to drive the bracket 1 to rotate.

It should be understood that when the heater has a coil 5, the controller is electrically connected to the coil 5, and the controller can control the on and off of the coil 5 so that the heating element 2 starts to heat or stops heating. In some embodiments, when the heater does not have a coil 5, the controller is electrically connected to the heating element 2, for example, the heating element 2 is a resistive heating, and the controller can control the on and off of the current of the heating element 2 so that the heating element 2 starts to heat or stops heating.

In one embodiment, the aerosol generating device further includes a negative pressure sensor, which is electrically connected to the controller. The negative pressure sensor senses the suction negative pressure and transmits an electrical signal to the controller, and the controller controls the coil 5 or the heating element 2 to turn on and off according to the electrical signal of the negative pressure sensor. When the user sucks on the suction nozzle section 220, the negative pressure sensor senses the suction negative pressure and transmits an electrical signal to the controller, and the controller controls the coil 5 to turn on, so that the heating element 2 heats up, and stimulates the aerosol generating matrix 210 to generate aerosol. Driven by the suction airflow, the aerosol enters the oral cavity through the suction nozzle section 220 to achieve suction. In this way, the user only needs to make a suction action to start the heating element 2, reducing the user's operation steps.

The negative pressure sensor can be arranged at any position of the airflow path according to actual conditions. For example, the negative pressure sensor can be located in the sleeve 6 or other positions of the aerosol generating device that can sense the suction negative pressure.
