Description

Technical Field

[0001] This application relates to the field of heat-not-burning technology, specifically to a heat-not-burning device. Background Technology

[0002] Heating methods for non-combustible heating devices include direct contact heating, hot air flow heating, electromagnetic heating, and infrared heating.

[0003] In infrared heating, the aerosol product is inserted into the light-transmitting tube. When infrared rays pass through the light-transmitting tube and irradiate the cigarette, the molecules in the cigarette absorb the infrared radiation energy, causing the molecules to vibrate more intensely and generate heat. This process achieves energy transfer, raising the temperature of the cigarette and thus heating it.

[0004] To ensure sufficient heating, the size of the light-transmitting tube needs to cover the entire area of ​​the aerosol product matrix section along its length. This results in a large heated area during the heating process, leading to hot aerosols in the early stages of heating and insufficient aerosol production in the later stages. Utility Model Content

[0005] This application provides a heat-not-burning device to solve the technical problems of scalding the mouth with aerosol generated in the early stage of use and insufficient aerosol generated in the later stage.

[0006] According to one aspect of this application, one embodiment provides a heating non-combustible device, comprising:

[0007] The housing has a mounting cavity and a socket communicating with the mounting cavity;

[0008] A light-transmitting tube is installed in the mounting cavity and is coaxially arranged with the socket. An aerosol product can be inserted into the light-transmitting tube through the socket in a first direction. The light-transmitting tube has a first region and a second region arranged in the first direction. The second region is located on the side of the first region facing the socket. The transmittance of the first region is greater than that of the second region.

[0009] An infrared heating element is located inside the mounting cavity and surrounds the light-transmitting tube. The infrared heating element is used to perform infrared heating on the aerosol product from the circumferential direction.

[0010] In one alternative embodiment, the light-transmitting tube is positioned at the middle of the first direction within the first region.

[0011] In one alternative embodiment, the light-transmitting tube has a third region located on the side of the first region away from the second region in the first direction, and the transmittance of the third region is less than that of the first region.

[0012] In one alternative embodiment, the transmittance of the third region is less than that of the second region.

[0013] In an optional embodiment, the transmittance of the first region is greater than or equal to 95%; and / or,

[0014] The transmittance of the second region and the transmittance of the third region are both greater than or equal to 60% and less than 95%.

[0015] In one alternative embodiment, the transmittance of the second region is 80%; and / or, the transmittance of the third region is 70%.

[0016] In one optional embodiment, the sidewall of the light-transmitting tube in the first region is a smooth sidewall, and the sidewalls of the light-transmitting tube in the second region and the third region are both rough sidewalls.

[0017] In one optional embodiment, the light-transmitting tube has a plurality of grooves on the sidewall of the second region and / or on the sidewall of the third region; the grooves extend in the first direction or are arranged around the socket.

[0018] In one alternative embodiment, the minimum radial dimension of the socket is smaller than the inner diameter of the light-transmitting tube, the sidewall of the socket is used to contact the aerosol product to limit the position of the aerosol product, and the inner wall of the light-transmitting tube is used to be spaced apart from the outer peripheral surface of the aerosol product.

[0019] In one optional embodiment, a heating cavity is formed within the mounting cavity, and both the light-transmitting tube and the infrared heating element are located within the heating cavity. The infrared heating element is fixed to the side wall of the light-transmitting tube, and the heating cavity is arranged around the light-transmitting tube. A heat insulation layer is provided on the cavity wall of the heating cavity.

[0020] The heated non-combustible device according to the above embodiment includes a housing and a light-transmitting tube and an infrared heating element located in the mounting cavity of the housing. The housing has a socket communicating with the mounting cavity. The light-transmitting tube is coaxially arranged with the socket. An aerosol product can be inserted into the light-transmitting tube through the socket in a first direction. The infrared heating element surrounds the light-transmitting tube and is used to perform infrared heating on the aerosol product from the circumferential direction. Since the light-transmitting tube has a first region and a second region arranged in the first direction, the second region is located on the side of the first region facing the socket in the first direction, and the transmittance of the first region is greater than that of the second region, so that in the first direction... The temperature of the substrate section in the first region, which is farther away from the aerosol product, is higher than that of the substrate section in the second region, which is closer to the filter section. This helps to reduce the heat transferred to the filter section, decrease its temperature, prevent deformation, and reduce the probability of burns from aerosol in the early stages of heating. Furthermore, in the later stages of heating, the heat transferred from the substrate section in the first region to the substrate section in the second region increases the heating and baking of the substrate section in the second region, which helps to increase the aerosol concentration in the later stages of heating and improves the user experience.

[0026] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods.

This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0027] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.

[0028] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0029] This application discloses a heat-not-burning device that uses infrared heating. A light-transmitting tube 2 surrounding an aerosol product 4 has a first region 21 and a second region 22 arranged in a first direction. The second region 22 is located on the side of the first region 21 facing the inlet 112 of the aerosol product 4. The transmittance of the first region 21 is set to be greater than that of the second region 22. This reduces the temperature on the aerosol product 4 near the filter section 42, prevents the filter section 42 from deforming, and reduces the probability of the aerosol burning the mouth in the early stage of heating. Furthermore, in the later stage of heating, the high temperature of the first region 21 diffuses to the second region 22, which helps to increase the aerosol concentration in the later stage of heating.

[0030] Please refer to Figures 1 to 4The heated non-combustible device of this application includes a housing 1, a light-transmitting tube 2, and an infrared heating element 3. The housing 1 has a mounting cavity 111 and an insertion port 112 communicating with the mounting cavity 111. The internal cavity of the housing 1 forms the mounting cavity 111. The insertion port 112 is located at one end of the mounting cavity 111 in a first direction, which is the insertion direction or extension direction of the aerosol product 4. Both the light-transmitting tube 2 and the infrared heating element 3 are located in the mounting cavity 111. The light-transmitting tube 2 is installed in the mounting cavity 111, and its position is relatively fixed with respect to the housing 1. The light-transmitting tube 2 has a circular tube structure, and the light-transmitting tube 2 and the insertion port 112 on the housing 1 are arranged coaxially to facilitate the insertion of the aerosol product 4 into the light-transmitting tube 2 through the insertion port 112 along the first direction. The infrared heating element 3 includes a heating film or heating wire. The infrared heating element 3 can be fixed on the outer wall of the light-transmitting tube 2, or the infrared heating element 3 can be fixed relative to the light-transmitting tube 2 and arranged at intervals from the light-transmitting tube 2. The infrared radiation generated by the infrared heating element 3 can pass through the light-transmitting tube 2 and irradiate the aerosol product 4 to achieve heating of the aerosol product 4.

[0031] After the aerosol product 4 is inserted into the light-transmitting tube 2, the light-transmitting tube 2 corresponds to the position of the matrix section 41 on the aerosol product 4 in the first direction, and the size of the light-transmitting tube 2 in the first direction is equal to the length of the matrix section 41 in the aerosol product 4. This ensures that the matrix section 41 of the aerosol product 4 is heated only by infrared heating, which helps to ensure that the matrix section 41 is fully heated and helps to reduce the heat loss of the entire heating non-combustion device.

[0032] The light-transmitting tube 2 has a first region 21 and a second region 22 in the first direction. The second region 22 is located between the first region 21 and the socket 112 in the first direction. The transmittance of the first region 21 is greater than that of the second region 22. After the aerosol product 4 is inserted into place, the infrared radiation energy received by the matrix segment 41 corresponding to the first region 21 is greater than that received by the matrix segment 41 corresponding to the second region 22. That is, the temperature of the part of the matrix segment 41 surrounded by the first region 21 is greater than the temperature of the part of the matrix segment 41 surrounded by the second region 22.

[0033] After the aerosol product 4 is inserted into the light-transmitting tube 2, the matrix section 41 of the aerosol product 4 is located inside the housing 1, and the filter section 42 of the aerosol product 4 is located outside the housing 1. The user's lips can wrap around the filter section 42 to draw out the aerosol generated by the matrix section 41. In this way, the temperature of the matrix section 41, which is farther away from the filter section 42 in the first direction and corresponds to the first region 21, is greater than the temperature of the matrix section 41, which is closer to the filter section 42 and corresponds to the second region 22. On the one hand, this helps to reduce the heat transferred to the filter section 42, reduce the temperature of the filter section 42, prevent the filter section 42 from deforming, and also reduce the probability of burning the lips with aerosol in the early stage of heating. On the other hand, in the later stage of heating of the heated non-combustible device, the heat transferred from the matrix section 41 corresponding to the first region 21 to the matrix section 41 corresponding to the second region 22 is used to increase the heating and baking of the matrix section 41 corresponding to the second region 22, which helps to increase the aerosol concentration in the later stage of heating and improve the user experience.

[0034] In some embodiments, please refer to Figures 2 to 4 The light-transmitting tube 2 is positioned in the middle of the first region 21 in the first direction. Thus, when the heating non-combustible device is in heating mode, the temperature of the substrate section 41 corresponding to the middle position of the light-transmitting tube 2 is higher. The middle position of the substrate section 41 can be heated first to generate aerosol, which helps to shorten the distance between the aerosol and the filter section 42, shortens the preheating time, and also helps to ensure the concentration of aerosol in the initial suction stage. Of course, in embodiments where the substrate section 41 corresponding to the first region 21 has a higher temperature, to reduce the probability of the aerosol scalding the nozzle in the early heating stage, the middle position of the light-transmitting tube 2 can also be positioned in the second region 22 in the first direction, with the first region 21 located on the side of the middle position of the light-transmitting tube 2 away from the insertion port 112.

[0035] In some embodiments, please continue to refer to Figures 2 to 4 In addition to the first region 21 and the second region 22, the light-transmitting tube 2 also has a third region 23. The three regions are staggered in the first direction. The third region 23 is located on the side of the first region 21 away from the second region 22 in the first direction, or the first region 21 is located between the second region 22 and the third region 23 in the first direction. The dimensions of the three regions in the first direction can be equal, or the dimensions of the second region 22 and the third region 23 in the first direction can be set to be smaller than the dimensions of the first region 21 in the first direction.

[0036] Furthermore, the transmittance of the third region 23 is set to be less than that of the first region 21. This means that the temperature of the portion of the matrix section 41 surrounded by the third region 23 is lower than the temperature of the portion of the matrix section 41 surrounded by the first region 21. This helps reduce the heat transferred to the light-transmitting tube 2 on the side away from the inlet 112 in the first direction, thus improving the heating efficiency of the heating-non-combustible device and reducing heat loss. Additionally, when the adapted aerosol product 4 has a deformable plug 43 structure on the side of the matrix section 41 away from the filter section 42, it can be connected to the third region 23... The corresponding substrate section 41, which has a lower temperature, reduces the heat transferred to the plug 43, thereby reducing the probability of plug 43 deformation and helping to reduce the probability of aerosol substrate falling off the substrate section 41 and contaminating the internal space of the light-transmitting tube 2. On the other hand, in the later stage of heating of the heating non-combustible device, the excess heat of the substrate section 41 corresponding to the first region 21 in the middle position can be transferred to the substrate section 41 corresponding to the third region 23, which helps to increase the baking and heating of the substrate section 41 corresponding to the third region 23 and helps to ensure the aerosol concentration in the later stage of heating.

[0037] In some embodiments, the transmittance of the third region 23 can be set to be less than that of the second region 22. Thus, the temperature of the matrix segment 41 corresponding to the third region 23 is lower than that of the matrix segment 41 corresponding to the second region 22. During the entire heating stage, the matrix segments 41 corresponding to the first region 21 and the second region 22 are heated first, which helps to ensure the aerosol concentration in the early stage of heating. In the later stage of heating, the matrix segments 41 corresponding to the first region 21 and the second region 22 are consumed first. The remaining matrix segments 41 corresponding to the third region 23 can be used to increase the aerosol concentration in the later stage of heating, thereby improving the user experience.

[0038] Of course, in other embodiments, the transmittance of the third region 23 can be set to be equal to or slightly greater than the transmittance of the second region 22. Since the aerosol flow direction is from the third region 23 to the first region 21 and then to the second region 22, the heat carried by the aerosol can be transferred from the matrix segment 41 corresponding to the third region 23 to the matrix segment 41 corresponding to the first region 21 and the matrix segment 41 corresponding to the second region 22. In this way, even if the temperature of the matrix segment 41 corresponding to the second region 22 heated by infrared is low, the heat transferred to the matrix segment 41 corresponding to the second region 22 by the aerosol at a higher temperature can increase the baking and heating of the matrix segment 41 corresponding to the second region 22. Thus, in the entire heating stage, the matrix segment 41 corresponding to the first region 21 and the matrix segment 41 corresponding to the second region 22 are heated and consumed first. The matrix segment 41 corresponding to the third region 23 that has not been consumed can also increase the aerosol concentration in the later stage of the heating stage, thereby improving the user experience.

[0039] In some embodiments, in the high-temperature resistant structure of the plug 43 of the aerosol product 4, the third region 23 can be omitted from the light-transmitting tube 2. The light-transmitting tube 2 only has a first region 21 and a second region 22. The size of the first region 21 in the first direction can be larger than the size of the second region 22 in the first direction. Similarly, the heat transferred from the matrix segment 41 corresponding to the first region 21 to the matrix segment 41 corresponding to the second region 22 can be used to increase the heating and baking of the matrix segment 41 corresponding to the second region 22, ensuring the aerosol concentration in the heated section and reducing the probability of burning the mouth with aerosol in the early stage of heating.

[0040] In some embodiments, please continue to refer to Figures 2 to 4 In order to improve energy utilization, the transmittance of the first region 21 of the light-transmitting tube 2 is set to be greater than or equal to 95%, such as 95%, 96% or 98%.

[0041] In some embodiments, also to improve energy efficiency, please refer to [the relevant documentation / reference]. Figures 2 to 4 The transmittance of the second region 22 and the third region 23 on the light-transmitting tube 2 is greater than or equal to 60%. For example, the transmittance of the second region 22 and the third region 23 can be 60%, 75% or 80%, as long as the transmittance of the second region 22 and the third region 23 are both less than 95%. Alternatively, when the transmittance of the first region 21 is greater than 95%, the transmittance of the second region 22 and the third region 23 can both be less than the transmittance of the first region 21.

[0042] In some embodiments, to meet the requirement that the transmittance of the third region 23 on the light-transmitting tube 2 is less than that of the second region 22, the transmittance of the second region 22 can be set to 80%, and the transmittance of the third region 23 to 70%.

[0043] In some embodiments, please refer to Figures 2 to 4 The first region 21, the second region 22, and the third region 23 in the light-transmitting tube 2 are integrally formed. The entire light-transmitting tube 2 can be made of quartz glass or other high-temperature resistant light-transmitting plastic materials. In other embodiments, the light-transmitting tube 2 includes three tube bodies corresponding to the first region 21, the second region 22, and the third region 23. The inner and outer diameters of the three tube bodies are the same. The three tube bodies can be bonded and fixed by high-temperature resistant adhesive, or the three tube bodies can be clamped and fixed in the mounting cavity 111 of the housing 1.

[0044] In some embodiments, the sidewall of the light-transmitting tube 2 in the first region 21 is a smooth sidewall to ensure that the first region 21 has a high transmittance, and the sidewalls of the light-transmitting tube 2 in the second region 22 and the third region 23 are rough sidewalls to ensure that the transmittance of the second region 22 and the third region 23 are both less than the transmittance of the first region 21.

[0045] Specifically, recesses or protrusions can be provided on the sidewalls of the second region 22 and the third region 23 to form rough sidewalls. Multiple recesses or protrusions can be provided, and the multiple recesses or protrusions are evenly distributed on the sidewalls of the second region 22 and the third region 23. The recesses or protrusions can be provided on the inner or outer sidewall of the light-transmitting tube 2 in the second region 22, or both the inner and outer sidewalls can be provided with recesses or protrusions. Similarly, the recesses or protrusions can also be provided on the inner and / or outer sidewalls of the third region 23.

[0046] In other embodiments, the transmittance of the second region 22 and the third region 23 can be changed by providing a high-temperature resistant coating on the sidewalls of the second region 22 and the third region 23.

[0047] In some embodiments, please refer to Figure 3 and Figure 4 The light-transmitting tube 2 has multiple grooves 24 on the sidewall of the second region 22 and / or the sidewall of the third region 23. Specifically, the grooves 24 can be located on the inner sidewall or the outer sidewall. In the embodiment where the infrared heater 3 is fixed to the outer sidewall of the light-transmitting tube 2, the grooves 24 can only be located on the inner sidewalls of the light-transmitting tube 2 in the second region 22 and the third region 23. Providing grooves 24 on the sidewall of the light-transmitting tube 2, or the structure with recesses or protrusions as described in the above embodiments, facilitates processing and reduces costs.

[0048] The grooves 24 provided on the sidewalls of the second region 22 and / or the third region 23 can be circumferential annular grooves surrounding the socket 112. Multiple grooves 24 are evenly spaced in the first direction to ensure the same transmittance in the same region. Alternatively, the grooves 24 can also be elongated slots extending in the first direction, with multiple grooves 24 evenly spaced in the circumferential direction surrounding the socket 112 to facilitate machining. The transmittance of the corresponding region can be changed by altering the groove width, groove depth, and distance between adjacent grooves 24. For example, decreasing the groove width, increasing the groove depth, or decreasing the distance between adjacent grooves 24 can increase the roughness of the corresponding region and decrease its transmittance; conversely, increasing the groove width, decreasing the groove depth, or increasing the distance between adjacent grooves 24 can decrease the roughness of the corresponding region and increase its transmittance.

[0049] After the aerosol product 4 is inserted into the light-transmitting tube 2 through the insertion port 112, in order to prevent the aerosol product 4 from detaching from the heating and non-combustible device, in some embodiments, the aerosol product 4 can be fixed in a specific position in the first direction by the side wall of the insertion port 112. The minimum radial dimension of the insertion port 112 of the housing 1 in the light-transmitting tube 2 is set smaller than the inner diameter of the light-transmitting tube 2. A protrusion can be provided on the side wall of the insertion port 112, extending radially inward toward the light-transmitting tube 2, for fitting or interference fit with the outer peripheral surface of the aerosol product 4, thereby restricting the aerosol product 4 from detaching. In other embodiments, a clamping member for clamping and fixing the aerosol product 4 can also be provided on the housing 1 between the insertion port 112 and the light-transmitting tube 2. The clamping member can be a rubber part, and the aerosol product 4 can be clamped and fixed by the deformable clamping member to restrict the aerosol product 4 from detaching.

[0050] In some embodiments, please refer to Figure 2 and Figure 3 The inner diameter of the light-transmitting tube 2 is larger than the outer diameter of the aerosol product 4. After the aerosol product 4 is inserted into the light-transmitting tube 2, the inner wall of the light-transmitting tube 2 and the outer peripheral surface of the aerosol product 4 are arranged at intervals. This avoids the light-transmitting tube 2 heating the aerosol product 4 through direct contact, which helps to avoid the aerosol product 4 from being overheated locally and generating impurities. Furthermore, heating the aerosol product 4 only by infrared heating helps to ensure that the temperature of the aerosol product 4 is uniformly distributed in the radial direction of the light-transmitting tube 2.

[0051] In some embodiments, the inner diameter of the light-transmitting tube 2 can be equal to or slightly larger than the outer diameter of the aerosol product 4. After the aerosol product 4 is inserted into the light-transmitting tube 2, the inner wall of the light-transmitting tube 2 is in contact with the outer peripheral surface of the aerosol product 4. The heat from the infrared heating element 3 can be transferred to the aerosol product 4 through direct contact with the light-transmitting tube 2, thus combining with the infrared heating method to improve the heating efficiency of the aerosol product 4 and increase the heat utilization rate of the heating non-combustible device. It should be noted that in the structure where the inner wall of the light-transmitting tube 2 is in contact with the outer peripheral surface of the aerosol product 4, the temperature of the light-transmitting tube 2 needs to be controlled to avoid excessively high local temperatures of the aerosol product 4 at the contact area, which could produce a burnt smell and off-gassing.

[0052] In some embodiments, please refer to Figure 2A heating cavity 124 is formed within the mounting cavity 111 of the housing 1. The light-transmitting tube 2 and the infrared heating element 3 are both located within the heating cavity 124. The infrared heating element 3 is fixed to the side wall of the light-transmitting tube 2, specifically to the outer side wall of the light-transmitting tube 2. The heating cavity 124 is arranged around the light-transmitting tube 2. The heating cavity 124 has a cavity side wall extending in a first direction. The cavity side wall of the heating cavity 124 and the light-transmitting tube 2 are spaced apart in a plane perpendicular to the first direction, so that the heating cavity 124 has a heat insulation function. A heat insulation layer is also provided on the cavity wall of the heating cavity 124. Specifically, the heat insulation layer is provided on the cavity side wall of the heating cavity 124. The heat insulation layer can reduce the heat transfer from the heating cavity 124 to the outside of the heating cavity 124, which helps to reduce the heat loss of the heating non-combustible device.

[0053] Specifically, the housing 1 includes an outer shell 11 and an inner shell 12. Both the mounting cavity 111 and the insertion port 112 can be formed by the outer shell 11. The inner shell 12 is fixedly installed at the insertion port 112. The inner shell 12 has an opening coaxially arranged with the insertion port 112. The protrusion for clamping the aerosol product 4 can be disposed on the side wall of the opening. The inner shell 12 is clamped and fixed to the insertion port 112 of the outer shell 11 in a first direction. The inner shell 12 includes a first cylindrical body 121 and a second cylindrical body 122 that are inserted and fitted in the first direction. The inner shell 12 also includes a base 123. The first cylinder 121 and the second cylinder 122 are inserted together. The base 123 is clamped and fixed between the first cylinder 121 and the second cylinder 122. The first cylinder 121, the second cylinder 122 and the base 123 enclose and form a heating cavity 124 that communicates with the insertion port 112. The light-transmitting tube 2 is clamped and fixed in the first direction between the inner side of the second cylinder 122 and the base 123. The inner wall of the second cylinder 122 forms the cavity sidewall of the heating cavity 124.

[0054] In some embodiments, the heated non-combustible device may adopt a top air intake method, where external gas enters from the inlet 112 between the first cylinder 121 and the second cylinder 122. The base 123 is provided with an air hole that communicates with the plug 43 of the aerosol product 4. The base 123 and the first cylinder 121 are also provided with a sealing cover 125 on the side facing away from the inlet 112 in the first direction. The sealing cover 125, the base 123, and the first cylinder 121 enclose an air intake chamber 126. External gas can enter the aerosol product 4 through the air intake chamber 126 and the air hole on the base 123 to achieve air intake.

[0055] In some embodiments, the heating non-combustible device may also adopt a bottom air intake method. An air inlet is provided on the outer shell 11, and an air intake channel is also provided inside the outer shell 11 to connect the air inlet with the air hole on the base 123. External gas enters the air intake channel from the air inlet and enters the aerosol product 4 through the air hole on the base 123 to achieve air intake.
