[0032] An embodiment of the present application discloses an aroma-enhancing structure 100, which can be applied to a heat-not-burn device 4 or a heat-not-burn aerosol product 2. For example, it can be applied in the aerosol product 2 and is located upstream of the mouthpiece section 22 in the air flow direction. It is used to generate aroma during the use of the heat-not-burn device 4 or the aerosol product 2. After being mixed with the aerosol generated by heating the aerosol product 2, it is used by the user, which helps to improve the user experience. Among them, the aroma-enhancing structure 100 is located upstream of the mouthpiece section 22 in the air flow direction, that is, when the air flow flows in the aerosol product 2 or in the heat-not-burn device 4, the air flow first passes through the aroma-enhancing structure 100 and then passes through the mouthpiece section 22.

[0033] The aroma-enhancing structure 100 disclosed in the embodiment of the present application, please refer to Figures 1 to 3 , which includes an aroma-enhancing fixing member 1 and an aroma-enhancing member 31. The aroma-enhancing fixing member 1 has a gas passage 11 for gas to pass through and a closed chamber 13 arranged around the gas passage 11. A plurality of air holes 12 are provided on the passage wall of the gas passage 11, and the air holes 12 communicate the closed chamber 13 with the gas passage 11.

[0034] In one embodiment, please continue to refer to Figures 1 to 3The outer contour of the aroma enhancement firmware 1 can be columnar, and the gas channel 11 can be arranged at the center position of the cross section of the aroma enhancement firmware 1. The extension direction of the gas channel 11 is the same as the extension direction of the column, and the gas channel 11 runs through the entire aroma enhancement firmware 1.

[0035] In one embodiment, the cross-sectional shape of the gas channel 11 can be circular to facilitate matching with the cross-sectional shape of the airflow channel 41 in the heating without combustion device 4; of course, in other embodiments, the cross-sectional shape of the gas channel 11 can also be a quadrilateral, triangle, ellipse or other special-shaped structures, as long as the aroma enhancement structure 100 is installed in the heating without combustion device 4 and the gas channel 11 of the aroma enhancement structure 100 can be connected with the airflow channel 41 in the heating without combustion device 4.

[0036] In one embodiment, please refer to Figures 1 to 3 , the cross-sectional dimensions of the gas channel 11 in its extending direction are equal everywhere, in the structure where the cross-sectional shape of the gas channel 11 is circular, the channel wall of the gas channel 11 is a cylindrical surface, and in the structure where the cross-sectional shape of the gas channel 11 is a quadrilateral or a triangle, the channel wall of the gas channel 11 is a prism surface; in this way, the flow velocity of the gas flow in each part of the gas channel 11 is equal. Alternatively, in other embodiments, the cross-sectional dimensions of the gas channel 11 in the direction of the gas flow may be gradually increased, or the cross-sectional dimensions of the gas channel 11 in the middle section of the gas flow direction may be set to be the largest.

[0037] The closed chamber 13 is arranged around the gas channel 11, and the fragrance enhancing component 31 is located in the closed chamber 13. The closed chamber 13 is an annular structure arranged around the gas channel 11. The fragrance enhancing component 1 has an outer peripheral surface 14 arranged around the closed chamber 13, and the outer peripheral surface 14 is the outer wall surface of the outer cavity wall of the closed chamber 13 away from the gas channel 11.

[0038] In one embodiment, please refer to Figures 1 to 3 The outer peripheral surface 14 of the fragrance enhancing firmware 1 can be set as a cylindrical surface to facilitate matching the outer contour surface of the aerosol product 2 and facilitate the assembly of the entire fragrance enhancing structure 100 in the aerosol product 2; of course, in other embodiments, the outer peripheral surface 14 of the fragrance enhancing firmware 1 can also be set as a prismatic surface or other non-arc transition outer surface, as long as the entire fragrance enhancing structure 100 can be assembled in the aerosol product 2 and the heat without burning device 4, and the gas channel 11 of the fragrance enhancing structure 100 can be connected with the airflow channel 41 of the heat without burning device 4 or with the channel for airflow in the aerosol product 2.

[0039] In one embodiment, please refer to Figures 1 to 3, the closed chamber 13 is a chamber with an annular structure. The chamber wall of the closed chamber 13 can fixedly encapsulate the fragrance enhancing member 31 within the closed chamber 13. The fragrance enhancing fixture 1 further has a first end face 15 and a second end face 16 arranged in the extending direction of the gas passage 11. Both the first end face 15 and the second end face 16 are annular faces arranged perpendicular to the extending direction of the gas passage 11. The first end face 15 and the second end face 16 are respectively connected to the outer peripheral face 14 of the fragrance enhancing fixture 1 and the passage wall face of the gas passage 11 to enclose and form the entire closed chamber 13. The closed chamber 13 can prevent the fragrance enhancing member 31 within the closed chamber 13 from contacting the external air through the outer peripheral face 14, the first end face 15, and the second end face 16 of the fragrance enhancing fixture 1. In this way, the rate of decrease in the amount and concentration of the fragrance due to the exposure of the fragrance enhancing member 31 to the air can be reduced.

[0040] In one embodiment, the passage wall face enclosing the gas passage 11 forms the inner peripheral face 17 of the fragrance enhancing fixture 1. The closed chamber 13 is not completely closed. In order to enable the fragrance generated by the fragrance enhancing member 31 within the closed chamber 13 to flow out of the gas passage 11 from the outlet of the gas passage 11 along with the aerosol flowing through the gas passage 11, air holes 12 are provided on the passage wall of the gas passage 11, that is, the air holes 12 are located on the inner peripheral face 17 of the fragrance enhancing fixture 1. The air holes 12 communicate the closed chamber 13 with the gas passage 11. Multiple air holes 12 can be provided, such as two, three, or more than four. The multiple air holes 12 can be evenly spaced in the circumferential direction of the gas passage 11, and can also be evenly spaced in the axial direction of the gas passage 11 to increase the flow area between the closed chamber 13 and the gas passage 11 through the multi-air hole structure without increasing the size of the air holes 12.

[0041] When there is an air flow passing through the gas passage 11, the Venturi principle can be utilized to form a negative pressure at a position near the air holes 12 within the closed chamber 13. The internal and external pressure difference between the closed chamber 13 and the gas passage 11 can bring the fragrance generated by the fragrance enhancing member 31 within the closed chamber 13 out of the air holes 12 into the gas passage 11 to achieve mixing with the aerosol. In this way, the aerosol flowing out of the outlet of the gas passage 11 has a fragrance. The fragrance enhancing structure 100 with such a structural arrangement can, while satisfying the normal discharge of the fragrance of the fragrance enhancing structure 100, utilize the closing effects of the outer peripheral face 14, the first end face 15, and the second end face 16 of the fragrance enhancing fixture 1 to reduce the rate of decrease in the amount and concentration of the fragrance of the fragrance enhancing member 31.

[0042] In some embodiments, the air holes 12 on the inner peripheral surface 17 of the fragrance-enhancing firmware 1 can be set as round holes, square holes or other special-shaped hole structures; in one embodiment, for the convenience of processing, the air holes 12 can be set as round holes. In addition, in order to prevent the fragrance-enhancing element 31 in the closed chamber 13 from leaking out through the air holes 12, and in order to reduce the contact area between the fragrance-enhancing element 31 and the external air of the closed chamber 13 through the air holes 12, the diameter of the air holes 12 is set not to be greater than 2.5 mm. For example, the diameter of the air holes 12 can be set to 2.5 mm, 2.4 mm, 2.3 mm or other sizes less than 2.3 mm, as long as it can ensure that the fragrance can be discharged from the closed chamber 13 to the gas channel 11 under the action of the pressure difference; of course, in other embodiments, affected by the processing accuracy, the diameter of the air holes 12 can also be set to 2.6 mm, 2.7 mm or other sizes slightly larger than 2.7 mm, as long as the fragrance-enhancing element 31 will not spontaneously overflow from the air holes 12 into the closed chamber 13.

[0043] In some embodiments, the fragrance-enhancing element 31 can generate fragrance after being heated. In one embodiment, the fragrance-enhancing element 31 includes a liquid storage element 32 and a fragrance liquid located in the liquid storage element 32. The liquid storage element 32 is made of a material with good water absorption or oil absorption, and the liquid storage element 32 is a porous structure; in one embodiment, the liquid storage element 32 can be made of one of PP (polypropylene), PA (polyamide), PET (polyethylene terephthalate), non-woven fabric, and integrated cotton. In other embodiments, the liquid storage element 32 can be made of multiple materials among PP, PA, PET, non-woven fabric, and integrated cotton. Each of the above-mentioned multiple materials is separately processed to form a porous structure and then mixed together to form the liquid storage element 32.

[0044] In some embodiments, the fragrance liquid is stored in the liquid absorption holes of the liquid storage element 32. The liquid storage element 32 has good liquid locking ability, which can prevent the fragrance liquid from directly leaking out of the closed chamber 13 through the air holes 12, and helps to reduce the fragrance attenuation rate of the fragrance-enhancing structure 100; the fragrance liquid contains low-boiling or medium-boiling perfume and flavor materials to facilitate the generation of fragrance after the fragrance liquid is heated. The fragrance liquid also contains nicotine and a propylene glycol solvent for dissolving the perfume and flavor materials, which can generate a sense of satisfaction while the fragrance liquid generates fragrance after being heated, and helps to improve the user experience.

[0045] In some other embodiments, the liquid storage element 32 is not provided in the fragrance-enhancing element 31, and the fragrance-enhancing element 31 can only include the fragrance liquid; or the fragrance-enhancing element 31 includes a fragrance gel or fragrance particles containing low-boiling or medium-boiling perfume and flavor materials, as long as it satisfies that the fragrance-enhancing element 31 can generate fragrance after being heated.

[0046] Since the fragrance - enhancing component 31 can produce fragrance only after being heated, there are certain requirements for the heat - resistance of the material of the fragrance - enhancing fixing member 1. In some embodiments, the fragrance - enhancing fixing member 1 can be made of one of PC (polycarbonate), PEEK (polyetheretherketone), PCTG (polyethylene terephthalate - 1,4 - cyclohexanedimethanol ester), and silica gel. Or in other embodiments, the fragrance - enhancing fixing member 1 can also be made of multiple materials among PC, PEEK, PCTG, and silica gel. The above - mentioned multiple materials can be mixed and processed to form the fragrance - enhancing fixing member 1. In this way, the service life of the entire fragrance - enhancing structure 100 can be increased by utilizing the heat - resistance of the above - mentioned materials.

[0047] An embodiment of the present application also provides a heat - not - burn device 4. Please refer to Figure 5 , the heat - not - burn device 4 includes a device main body 40, a heating member 42, and the fragrance - enhancing structure 100 in any of the above - mentioned embodiments. The device main body 40 has an air - flow passage 41 for air to pass through. For example, the device main body 40 includes a housing, and the housing has an air inlet and an air outlet communicated with the air - flow passage 41. The heating member 42 is installed in the device main body 40.

[0048] In one embodiment, the heating member 42 can adopt a needle - type heating body. One end of the heating member 42 is fixed on the device main body 40, and the other end extends into the air - flow passage 41. There is a receiving cavity communicated with the air - flow passage 41 at the air outlet of the device main body 40. The aerosol product is installed in the receiving cavity. After the aerosol product is installed in place, the needle - type heating body penetrates into the aerosol product to heat the aerosol product by direct contact.

[0049] In another embodiment, the heating member 42 includes a heating cylinder. The heating cylinder is installed on the device main body 40. The heating cylinder encloses a part of the air - flow passage 41. The heating member 42 further includes a heat - exchange member installed in the heating cylinder. The heat - exchange member has a heat - exchange air passage communicated with the air - flow passage 41. There is a receiving cavity for the aerosol product to be inserted at the air outlet of the device main body 40. After the aerosol product is inserted into the receiving cavity, the aerosol product and the heating member 42 are arranged at intervals in the extending direction of the air - flow passage 41 to avoid the aerosol product directly contacting the heating member 42. During the working process of the heating member 42, the heating cylinder transfers heat to the heat - exchange member, and the heat - exchange member heats the air flowing through the heat - exchange air passage to form a hot air flow, and the hot air flow heats the aerosol product to generate aerosol.

[0050] In some other embodiments, the aerosol product can also be built into the device main body 40. When disassembling the aerosol product, the housing of the device main body 40 needs to be opened. In this way, the receiving cavity for accommodating the aerosol product is arranged at an interval from the air outlet of the device main body 40.

[0051] The fragrance enhancing structure 100 is installed on the device main body 40. The gas passage 11 of the fragrance enhancing structure 100 is communicated with the air flow passage 41 on the device main body 40. For example, the fragrance enhancing structure 100 can be clamped on the device main body 40 in the extending direction of the gas passage 11. The device main body 40 is provided with a seal at the position where the air flow passage 41 is communicated with the gas passage 11, and the sealing cooperation between the fragrance enhancing structure 100 and the device main body 40 can be realized through the seal to avoid gas leakage.

[0052] The fragrance enhancing structure 100 is arranged at an interval from the heating element 42 in the extending direction of the air flow passage 41 to prevent the fragrance enhancing firmware 1 of the fragrance enhancing structure 100 from being damaged due to the high temperature during the operation of the heating element 42.

[0053] In one embodiment, the fragrance enhancing structure 100 is located upstream of the heating element 42 in the extending direction of the air flow passage 41, that is, in the gas flow direction in the device main body 40. Or rather, the fragrance enhancing structure 100 is located between the air inlet of the device main body 40 and the heating element 42 in the extending direction of the air flow passage 41. The fragrance enhancing structure 100 is arranged close to the heating element 42. The heating element 42 can transfer heat to the fragrance enhancing structure 100 in the extending direction of the air flow passage 41 to heat the fragrance enhancing member 31 in the closed chamber 13. After being heated, the fragrance enhancing member 31 can generate fragrance. When there is air flow in the gas passage 11, the fragrance can be sucked from the closed chamber 13 into the gas passage 11 along the air holes 12 by using the pressure difference between the closed chamber 13 and the gas passage 11. After the fragrance is mixed with the aerosol in the air flow passage 41, it is discharged from the air outlet of the device main body 40.

[0054] In some embodiments, please continue to refer to Figure 5 , the fragrance enhancing structure 100 can also be arranged downstream of the heating element 42 in the extending direction of the air flow passage 41, that is, the fragrance enhancing structure 100 is located between the air outlet of the device main body 40 and the heating element 42; the fragrance enhancing structure 100 can be arranged between the accommodating chamber for accommodating the aerosol product and the heating element 42, or can also be arranged between the accommodating chamber and the air outlet of the device main body 40. For example, if the heated non-combustible device 4 has a mouthpiece, the mouthpiece is installed at the air outlet of the device main body 40, and the mouthpiece encloses to form part of the air flow passage 41. The fragrance enhancing structure 100 can be installed between the mouthpiece and the device main body 40 to communicate the gas passage 11 with the air flow passage 41.

[0055] In some embodiments, in order to avoid an increase in the draw resistance of the heat-not-burn device 4 due to the setting of the flavor-enhancing structure 100 in the heat-not-burn device 4, the gas channel 11 in the selected flavor-enhancing structure 100 is provided with a first mating interface 111 communicating with the air flow channel 41 in the device main body 40. Correspondingly, the air flow channel 41 is provided with a second mating interface 411 communicating with the gas channel 11. It is set that the geometric center of the first mating interface 111 faces the geometric center of the second mating interface 411 in the orientation of the first mating interface 111. In addition, it is also set that the opening size of the first mating interface 111 is greater than or equal to the opening size of the second mating interface 411, so as to ensure that at the connection position of the flavor-enhancing structure 100 and the device main body 40, the cross-sectional area of the effective channel for the air flow to pass through in the flavor-enhancing structure 100 is greater than or equal to the cross-sectional area of the effective channel for the air flow to pass through in the device main body 40.

[0056] In one embodiment, it is set that the cross-sectional shapes of both the gas channel 11 and the air flow channel 41 are circular, the gas channel 11 is coaxially arranged with the air flow channel 41 at the part in contact with the flavor-enhancing structure 100, and the diameter of the first mating interface 111 on the gas channel 11 is greater than or equal to the diameter of the second mating interface 411.

[0057] In another embodiment, it is set that the shapes of the first mating interface 111 and the second mating interface 411 are different. It only needs to be ensured that in any direction passing through the geometric center of the first mating interface 111, the opening size of the first mating interface 111 is greater than or equal to the opening size of the second mating interface 411; or it can also be understood that the orthographic projection of the second mating interface 411 in the plane where the first mating interface 111 is located is located inside the first mating interface 111, or the outer contour of the orthographic projection of the second mating interface 411 in the plane where the first mating interface 111 is located coincides with the outer contour of the first mating interface 111.

[0060] The flavor enhancing structure 100 can be connected to any position in the aerosol product 2 other than the aerosol matrix section 21 and the mouthpiece section 22. In some embodiments, please refer to Figure 4 , the flavor enhancing structure 100 is connected between the mouthpiece section 22 and the aerosol matrix section 21, or can also be connected to the side of the aerosol matrix section 21 facing away from the mouthpiece section 22; the air flow channel 41 in the flavor enhancing structure 100 communicates with the flow channel in the aerosol matrix section 21 and also communicates with the micropores for air flow in the mouthpiece section 22.

[0061] In one embodiment, the flavor enhancing structure 100 can be fixed in the outer paper tube by bonding and winding, or fixed in the rigid tube by filling to achieve the connection between the flavor enhancing structure 100 and the aerosol matrix section 21 and the mouthpiece section 22.

[0062] In some embodiments, the aerosol product 2 further includes an intermediate connection section 20 connected between the aerosol matrix section 21 and the mouthpiece section 22. The intermediate connection section 20 can be fixed in the outer paper tube by bonding and winding, or the intermediate connection section 20 can also be fixed in the rigid tube by filling. The intermediate connection section 20 includes a support section 23 and / or a cooling section 24. The support section 23 can be made of plastic, silica gel or integral cotton, and it is used to support the entire aerosol product 2. The cooling section 24 can be formed by setting cooling materials and is used to cool the high-temperature aerosol. The flavor enhancing structure 100 can be installed between the intermediate connection section 20 and the aerosol matrix section 21, or between the intermediate connection section 20 and the support section 23, or can also be installed between the support section 23 and the cooling section 24. The flavor enhancing structure 100 can serve as the flavor enhancing section in the aerosol product 2.

[0063] In the above embodiments, the flavor enhancing structure 100 can act as the support section 23 to support the entire aerosol product 2, or the flavor enhancing structure 100 can also act as the cooling section 24 to reduce the temperature of the generated aerosol; or in other embodiments, the flavor enhancing structure 100 can also be embedded in the support section 23 or the cooling section 24.

[0064] In the above embodiments, after the aerosol matrix section 21 is heated to generate aerosol, the aerosol with heat will pass through the gas channel 11 of the flavor enhancing structure 100 during the process of flowing towards the mouthpiece section 22. In the gas channel 11, the aerosol with heat can transfer heat to the flavor enhancing element 31 in the flavor enhancing structure 100. After the flavor enhancing element 31 is heated, it generates fragrance. Under the action of the internal and external pressure difference between the gas channel 11 and the closed chamber 13, the fragrance generated in the closed chamber 13 can enter the gas channel 11 through the pores 12. The fragrance is mixed with the aerosol and flows towards the mouthpiece section 22 for the user to use.

[0065] In one embodiment, the aerosol article 2 further includes a plug 25. The plug 25 is connected to one side of the aerosol matrix section 21 facing away from the mouthpiece section 22. The plug 25 is used for sealing and cooperating with an outer paper tube or a rigid tube to prevent the aerosol matrix section 21 from disengaging from the outer paper tube or the rigid tube. The flavor enhancing structure 100 can be installed between the plug 25 and the aerosol matrix section 21, or the flavor enhancing structure 100 can also be embedded in the plug 25. The plug 25 has micropores for air flow to pass through, and the gas channel 11 of the flavor enhancing structure 100 communicates with the micropores of the plug 25.

[0066] In some embodiments, the heat in the heat-not-burn device can be transferred to the aerosol matrix section 21 and then from the aerosol matrix section 21 to the flavor enhancing member 31 of the flavor enhancing structure 100 to cause the flavor enhancing member 31 to generate fragrance. Alternatively, the heat in the aerosol generating matrix can be transferred to the flavor enhancing member 31 in the flavor enhancing structure 100 through the plug 25 to cause the flavor enhancing member 31 to generate fragrance. The air flow enters the gas channel 11 of the flavor enhancing structure 100 from the air flow channel 41 of the heat-not-burn device along the channel of the plug 25. Due to the pressure difference between the gas channel 11 and the closed chamber 13, the fragrance in the closed chamber 13 enters the gas channel 11 from the air holes 12. After being mixed with the aerosol, the fragrance flows towards the mouthpiece section 22 and is used by the user.
