Description

Technical Field

[0001] This application relates to the technical field of novel tobacco products, and more specifically, to an expandable aerosol product and smoking device. Background Technology

[0002] The new tobacco products use reconstituted tobacco as the aerosol generation matrix, and release tobacco components through electronic heating or low-temperature baking of reconstituted tobacco, which are products that do not require combustion and do not produce secondhand smoke.

[0003] In related technologies, the aerosol generating matrix inside the novel tobacco product is wrapped around the heating element. When the aerosol generating matrix is ​​heated to generate aerosol, the components in the matrix are consumed, and the substrate will shrink. The substrate itself will shrink and deform inward due to stress. When the aerosol generating matrix is ​​completely consumed, the condensed aerosol generating matrix is ​​easy to stick to the heating element and is difficult to separate. External force is required to separate the aerosol generating matrix from the heating element.

[0004] In summary, how to prevent the aerosol generation matrix from sticking to the heating element after heating is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, the purpose of this application is to provide an expandable aerosol product and smoking device, so that the aerosol generating matrix is ​​not easily adhered to the heating element after heating.

[0006] To achieve the above objectives, this application provides the following technical solution:

[0007] An expandable aerosol product includes a fixed substrate and one or more aerosol generating matrices, wherein the fixed substrate and a heating element are fixed relative to each other, and the aerosol generating matrices are fixedly connected to the side of the fixed substrate facing the heating element, with a single aerosol generating matrix located on one side of the heating element.

[0008] Preferably, there are two aerosol generating substrates and two fixed substrates. The two aerosol generating substrates are located on opposite sides of the heating element. Two edge gaps are formed between the two fixed substrates. The two edge gaps are located on opposite sides of the heating element. A connector is connected between the two fixed substrates. The connector is located within the edge gap.

[0009] Preferably, the connector is an elastic element, and when the connector is at its minimum size along the arrangement direction of the two aerosol generating matrices, the distance between the two aerosol generating matrices is greater than or equal to the thickness of the heating element.

[0010] Preferably, one of the connecting bodies is located at one of the edge gaps, and a tension body unit is fixedly disposed between the connecting body and the two fixed bases respectively.

[0011] Preferably, the distance between the deepest depression and the highest convex point on the side surface of the aerosol generating matrix facing the heating element along a direction perpendicular to this surface is less than 10% of the thickness of the aerosol generating matrix.

[0012] An aerosol smoking device includes a smoking device shell, a receiving cavity provided inside the smoking device shell, a heating element disposed inside the receiving cavity, an air inlet channel and an air outlet channel provided on the smoking device shell, one end of the air inlet channel and the air outlet channel communicating with the receiving cavity, and the other end communicating with the outside. It also includes the aforementioned expandable aerosol product, wherein the fixed substrate and the aerosol generating matrix are located inside the receiving cavity.

[0013] Preferably, the smoking device housing is fixedly connected to a positioning body, the positioning body is located in the receiving cavity, and a mating structure is fixedly provided on the fixed base. The positioning body applies a resisting force to the mating structure to fix the fixed base and the smoking device housing relative to each other.

[0014] Preferably, the mating structure is a fixed wing plate, which is fixedly connected to one side of the fixed base. The fixed wing plates of the two fixed bases face each other. The positioning body is a fixed protrusion plate, which is fixedly connected to the cavity wall of the receiving cavity.

[0016] Preferably, a through-hole groove is provided on both the aerosol generating matrix and the fixed substrate, and the through-hole groove is connected to the internal space of the receiving cavity.

[0017] The expanded aerosol products and smoking devices provided in this application have an aerosol generating matrix located on one side of the heating element, which does not wrap or surround the heating element. The aerosol generating matrix is ​​fixedly connected to the fixed base located on the side away from the heating element. When the aerosol generating matrix shrinks and deforms due to heat, its overall deformation direction is away from the heating element, so it will not stick to the heating element.

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

This application discloses an expansion aerosol product and smoking device.

[0032] The core of this application is to provide an expandable aerosol product and smoking device.

[0033] Please refer to Figure 1 and Figure 2 .

[0034] The expanded aerosol product provided in this application includes a fixed substrate 2 and one or more aerosol generating substrates 1. The fixed substrate 2 is used to connect with the aerosol generating substrate 1. The fixed substrate 2 is kept relatively fixed to the heating element 4 fixed in the smoking device. The aerosol generating substrate 1 is fixedly connected to the side of the fixed substrate 2 facing the heating element 4. The aerosol generating substrate 1 generates aerosol after being heated by the heating element 4.

[0035] A single aerosol generating matrix 1 is located on one side of the heating element 4. If there are multiple aerosol generating matrices 1, they are evenly arranged around the heating element 4. There is a gap between two adjacent aerosol generating matrices 1, that is, a single aerosol generating matrix 1 does not form a wrapping shape around the heating element 4. When the aerosol generating matrix 1 is heated and shrinks, its surface facing the heating element 4 will move closer to the fixed base 2 and away from the heating element 4, so that it will not stick to the heating element 4.

[0036] The expanded aerosol products and smoking devices provided in this application will be described in more detail below with reference to the accompanying drawings and specific embodiments.

[0037] In one specific implementation, reference is made to... Figures 2-4 .

[0038] Specifically, there are two aerosol generating substrates 1 and two fixed substrates 2, with each aerosol generating substrate 1 connected to a corresponding fixed substrate. The two aerosol generating substrates 1 are located on opposite sides of the heating element 4.

[0039] Two aerosol generating substrates 1 are symmetrically arranged relative to the heating element 4. The heating element 4 can be plate-shaped or cylindrical (not shown in the figure). Therefore, the aerosol generating substrate 1 can be sheet-shaped, semi-cylindrical, or semi-cylindrical, so that the surface of the aerosol generating substrate 1 facing the heating element 4 can adhere to the surface of the heating element 4 or form a uniform gap. Correspondingly, the fixing base 2 is in the shape of a straight plate or an arc plate, so that it can adhere to the surface of the aerosol generating substrate 1 facing away from the heating element 4.

[0040] Two edge gaps are formed between the side edges of the two fixed bases 2. The two edge gaps are located on opposite sides of the heating element 4. A connector 3 is connected between the two fixed bases 2. The connector 3 is located in the edge gap. The connector 3 is used to maintain a relatively stable connection and positional relationship between the two fixed bases 2.

[0041] The fixing base 2 is preferably a rigid material that is not easily deformed. Its material is metal, plastic or paper hardboard. When the fixing base 2 is made of metal, its thickness is between 0.15-0.5mm. When the fixing base 2 is made of plastic, its thickness is between 0.3-0.8mm. When the fixing base 2 is made of paper hardboard, its thickness is between 0.6-1mm.

[0042] The connector 3 can be a rigid object or an elastic element. When a rigid object is selected, the deformation of the rigid object should be less than 10 μm.

[0043] When the connector 3 is an elastic element, when the connector 3 is at its minimum size along the arrangement direction of the two aerosol generating matrices 1, the distance between the two aerosol generating matrices 1 is greater than or equal to the thickness of the heating element 4. That is, a gap can be formed between the aerosol generating matrices 1 and the heating element 4, or the two are in contact but not touching, thereby ensuring that the aerosol generating matrices 1 and the heating element 4 will not stick together due to compression.

[0044] The number of connectors 3 can be the same as the number of edge gaps, which is two, and each connector 3 is located in one edge gap.

[0045] In another implementation, such as Figures 5-7As shown, only one connector 3 is provided, and it is a rigid component. Specifically, connector 3 is located at one of the edge gaps. At the same time, a tension body unit 31 is fixedly provided between connector 3 and the two fixed bases 2. The tension body unit 31 is a tie structure between connector 3 and fixed base 2, which is used to improve the connection stability and morphological support of connector 3 to the two fixed bases 2, thereby improving the relative dimensional stability of the two fixed bases 2 and aerosol generation matrix 1.

[0046] Based on any of the above embodiments, regardless of the shape of the aerosol generating matrix 1, the distance between the deepest depression and the highest convex point on the side surface facing the heating element 4 along the direction perpendicular to this surface is less than 10% of the thickness of the aerosol generating matrix 1. As the aerosol generating matrix 1, its surface roughness is low, so the aerosol generating matrix 1 itself has a relatively uniform thickness distribution, and when heated, the shrinkage changes of each part show a high degree of consistency.

[0047] like Figures 8-11 As shown, the aerosol smoking device provided in this application includes a smoking device shell 5 and the aforementioned expanded aerosol product. The smoking device shell 5 is provided with a receiving cavity 51, and the fixed base 2 of the aerosol product and the aerosol generating matrix 1 can both be located in the receiving cavity 51; a heating element 4 is also fixedly provided in the receiving cavity 51.

[0048] The smoking device housing 5 is provided with an air inlet channel 53 and an air outlet channel 52. One end of the air inlet channel 53 and the air outlet channel 52 are connected to the receiving cavity 51, and the other end is connected to the outside. The airflow enters the receiving cavity 51 from the air inlet channel 53, and then flows out from the air outlet channel 52 carrying the aerosol generated by the aerosol product.

[0049] In one specific implementation, reference is made to... Figure 9 and Figure 10 .

[0050] Specifically, the smoking device shell 5 is fixedly connected to a positioning body, and a mating structure is fixedly provided on the fixed base 2; the positioning body is located in the receiving cavity 51, and the positioning body applies abutting force to the mating structure based on the smoking device shell 5. Through the positional limitation relationship and static friction between the two, the fixed base 2 and the smoking device shell 5 are relatively fixed, so that the above-mentioned expanded aerosol product exists stably in the receiving cavity 51.

[0051] Specifically, such as Figures 8-10 As shown, the mating structure is configured as a fixed wing plate 21, which is fixedly connected to one side edge of the fixed base 2 and the two can be integrally formed. There are two fixed wing plates 21 on a single fixed base 2. The surfaces of the two fixed wing plates 21 on the two fixed bases 2 are facing each other.

[0052] The positioning body is a fixed protrusion 54, which is fixedly connected to the cavity wall of the receiving cavity 51 away from the air outlet channel 52. There are two fixed protrusions 54, which are located on opposite sides of the heating element 4. When the aerosol product is placed in the installation position in the receiving cavity 51, both fixed protrusions 54 are located between the two fixed bases 2, and each fixed protrusion 54 simultaneously abuts against the surface of the opposite fixed wing plates 21 of the two fixed bases 2. Thus, the aerosol product is held in a clamping state by the paired fixed wing plates 21. Under the action of static friction, the fixed base 2 and the aerosol generating matrix 1 on it are able to maintain a fixed position with the fixed protrusions 54 and the receiving cavity 51.

[0053] The height of the heating element 4 and the fixing protrusion 54 exceeds two-thirds of the height of the fixing base 2.

[0054] In another specific embodiment, when the connector 3 is an elastic element, the positioning body does not need to be set inside the smoking device housing 5. During assembly, the aerosol product is contracted by pressing the fixing base 2. After the aerosol product enters the receiving cavity 51, it is released. After being released, the elastic force of the connector 3 will press the fixing base 2 against the inner wall of the receiving cavity 51, thereby realizing the positioning and installation of the fixing base 2 inside the smoking device housing 5.

[0055] Based on the above embodiments, such as Figures 8-10 As shown.

[0056] Specifically, the connector 3 is the packaging body 32. Since the fixing plate 54 supports the fixing base 2 from the inside out, the packaging body 32 can be a flexible part. The minimum distance between the two fixing bases 2 is limited by the fixing plate 54, so that the relative distance between the two fixing bases 2 meets the distance requirements of the aerosol generation matrix 1.

[0057] There are two packaging bodies 32, located on opposite sides of the heating element 4. Both the aerosol generating matrix 1 and the heating element 4 are located within the space formed by the two packaging bodies 32. The packaging bodies 32 can extend and cover the side edges of the aerosol generating matrix 1 and the surface of the fixing wing plate 21.

[0058] Based on the above embodiments, such as Figure 11 As shown.

[0059] Specifically, one end of the air intake channel 53 that connects to the receiving cavity 51 is located on the side wall of the cavity where the fixed protrusion 54 is located. A through hole groove 11 is provided on the aerosol generating matrix 1 and the fixed base 2. The through hole groove 11 is vertical. That is, after the external airflow enters the receiving cavity 51, the aerosol generating matrix 1 can generate airflow, which is conducive to the rapid discharge of the aerosol it generates and the delivery to the external space through the air outlet channel 52.
