Description

Technical Field

[0001] This application relates to the field of heating non-combustible devices, and particularly to a heating component and a heating non-combustible device. Background Technology

[0002] Heated non-combustible devices are a type of product that uses the thermal effect of a heating element to heat an aerosol generating product placed inside, so that the aerosol generating product generates aerosol without combustion.

[0003] During the use of a heated non-combustible device, the aerosol generating product is inserted into the heating element of the device. When the user performs suction, outside air enters the heating element, mixes with the aerosol generated by the aerosol generating product, and is then drawn out. Compared to the temperature inside the heating element, the outside air temperature is lower. To prevent the air from excessively lowering the temperature of the aerosol generating product, the heating element in the heating component of the heated non-combustible device is usually designed to be larger in size and mass to preheat the air entering the device.

[0004] The increased size and mass of the heating element in the heating assembly leads to an increase in the heat capacity of the heating element, which significantly reduces the heating rate. This requires a longer heating time during use, and also increases energy consumption, reducing the battery life of the heating non-combustion device. Utility Model Content

[0005] This application provides a heating component and a non-combustible heating device, which can preheat air without significantly affecting heating time and energy consumption. The technical solution is as follows:

[0006] In a first aspect, embodiments of this application provide a heating assembly, which includes a heating cylinder and a heat-conducting cylinder. One end of the heating cylinder has an opening and the other end is closed. Both ends of the heat-conducting cylinder have openings. The heat-conducting cylinder is located inside the heating cylinder. At least one air inlet channel is formed between the outer wall of the heat-conducting cylinder and the inner wall of the heating cylinder. The air inlet channel communicates with the inner side of the heat-conducting cylinder.

[0007] In some examples, the inner wall of the heating cylinder has a plurality of first strip-shaped protrusions distributed circumferentially along the heating cylinder, the first strip-shaped protrusions extending along the length of the heating cylinder, the first strip-shaped protrusions contacting the outer wall of the heat-conducting cylinder, and adjacent first strip-shaped protrusions, the outer wall of the heat-conducting cylinder, and the inner wall of the heating cylinder forming the air intake channel.

[0008] In some examples, the outer wall of the heat-conducting cylinder has a plurality of second strip-shaped protrusions distributed circumferentially along the heat-conducting cylinder and extending along the length of the heat-conducting cylinder. The second strip-shaped protrusions contact the inner wall of the heating cylinder, and adjacent second strip-shaped protrusions, the outer wall of the heat-conducting cylinder, and the inner wall of the heating cylinder form the air intake channel.

[0009] In some examples, the end of the heat-conducting cylinder abuts against the closed end of the heating cylinder.

[0010] In some examples, the sidewall of the heat-conducting cylinder has multiple through holes.

[0011] In some examples, the surface of the heat-conducting cylinder is covered with a film layer, which includes at least one of a silver layer and an infrared coating.

[0012] In some examples, the inner wall of the heating cylinder has a plurality of support protrusions located at one closed end of the heating cylinder and the plurality of support protrusions are arranged at intervals along the circumference of the heating cylinder.

[0013] In some examples, the heating assembly further includes a heating element located outside the heating cylinder and in contact with the outer surface of the heating cylinder.

[0014] In some examples, the heating element has a groove on its exterior, the groove being located on the end face of a closed end of the heating element, and the heating element being located in the groove.

[0015] In some examples, the heating assembly further includes a stop located in the groove and on the side of the heating element away from the end face of the heating cylinder, to limit the displacement of the heating element in the depth direction of the groove.

[0016] In some examples, the heating element is located on the outer wall of the heating cylinder, covering at least a portion of the outer wall of the heating cylinder.

[0017] Secondly, embodiments of this application also provide a heating non-combustible device, the heating non-combustible device including a housing and any of the heating components as described in the first aspect, the housing having an insertion hole, the heating component being located in the housing, and the heating cylinder having an open end facing the insertion hole.

[0018] The beneficial effects of the technical solutions provided in this application include at least the following:

[0019] By setting an opening at one end of the heating cylinder and placing a heat-conducting cylinder inside, with openings at both ends of the heat-conducting cylinder, the aerosol-generating product can be inserted into the heat-conducting cylinder during use. The heat generated by the heating cylinder directly or indirectly acts on the aerosol-generating product. An air inlet channel is formed between the outer wall of the heat-conducting cylinder and the inner wall of the heating cylinder, and this channel is connected to the inner side of the heat-conducting cylinder. During the suction process, air first enters the air inlet channel and then enters the heat-conducting cylinder to interact with the aerosol-generating product. As the air flows through the air inlet channel, it is preheated by the walls of the heating cylinder and the heat-conducting cylinder, and its temperature gradually increases. By setting up the heat-conducting cylinder, the air flow path within the heating assembly is increased. Preheating is achieved using the walls of the heating cylinder and the heat-conducting cylinder without increasing the size of the heating cylinder. The increase in mass of the heating assembly is only slightly increased by the mass of the heat-conducting cylinder, resulting in minimal impact on heat melting. This allows for air preheating without significantly affecting heating time and energy consumption. Attached Figure Description

[0039] Figure 1 This is a schematic diagram of the structure of a heating assembly provided in an embodiment of this application, such as... Figure 1 As shown, the heating assembly includes a heating cylinder 10 and a heat-conducting cylinder 20. One end of the heating cylinder 10 has an opening, and the other end is closed. Both ends of the heat-conducting cylinder 20 have openings. The heat-conducting cylinder 20 is located within the heating cylinder 10, and at least one air inlet channel 10a is formed between the outer wall of the heat-conducting cylinder 20 and the inner wall of the heating cylinder 10. The air inlet channel 10a communicates with the inner side of the heat-conducting cylinder 20.

[0040] An opening is provided at one end of the heating cylinder 10, and a heat-conducting cylinder 20 is placed inside the heating cylinder 10. Both ends of the heat-conducting cylinder 20 have openings. During use, the aerosol-generating product can be inserted into the heat-conducting cylinder 20, and the heat generated by the heating cylinder 10 directly or indirectly acts on the aerosol-generating product. An air inlet channel 10a is formed between the outer wall of the heat-conducting cylinder 20 and the inner wall of the heating cylinder 10. The air inlet channel 10a communicates with the inner side of the heat-conducting cylinder 20, so that during the suction process, air first enters the air inlet channel 10a and then enters the heat-conducting cylinder 20 to interact with the aerosol-generating product. As the air flows through the air inlet channel 10a, it is preheated by the cylinder walls of the heating cylinder 10 and the heat-conducting cylinder 20, and its temperature gradually increases. By setting up the heat-conducting cylinder 20, the path for air to flow in the heating component is increased. Preheating is achieved using the walls of the heating cylinder 10 and the heat-conducting cylinder 20 without increasing the size of the heating cylinder 10. The mass of the heating component is only increased by the mass of the heat-conducting cylinder 20. The increase in mass is small and has little impact on heat melting. Air can be preheated without significantly affecting heating time and energy consumption.

[0041] The heating element 10 can be made of metal or non-metal materials.

[0042] For example, the heating element 10 may be made of at least one of aluminum, magnesium, copper, aluminum alloy, magnesium alloy, and copper alloy.

[0043] For example, the heating element 10 may also be made of graphite.

[0044] The heat-conducting cylinder 20 can be made of metal, such as metal foil. The metal foil is very thin, which has little impact on the overall mass of the heating component and its heat capacity.

[0045] For example, the heat-conducting cylinder 20 may be made of aluminum foil.

[0046] The mass of the heat-conducting cylinder 20 can be 0.01 g to 0.1 g, for example, the mass of the heat-conducting cylinder 20 can be 0.06 g.

[0047] The outer wall of the heat-conducting cylinder 20 can be connected to the inner wall of the heating cylinder 10 to promote heat exchange between the heating cylinder 10 and the heat-conducting cylinder 20.

[0048] For example, the heat-conducting cylinder 20 and the heating cylinder 10 can be connected by ultrasonic welding or hot pressing.

[0049] In some examples, the surface of the heat-conducting cylinder 20 may be covered with a film layer, including at least one of a silver layer and an infrared coating.

[0050] A film layer is applied to the surface of the heat-conducting cylinder 20 to improve some of its properties. For example, silver has excellent thermal conductivity; by applying a silver layer to the surface of the heat-conducting cylinder 20, its thermal conductivity can be further improved, resulting in faster heating and a more uniform temperature distribution on the surface. An infrared coating is formed from a material with high emissivity, exhibiting high emissivity. During the operation of the heating assembly, this enhances the heat-conducting cylinder 20's ability to generate outward thermal radiation, thereby better preheating the air and better transferring heat to the aerosol-generated product.

[0051] For example, the membrane layer may cover part or all of the outer sidewall and part or all of the inner sidewall of the heat-conducting cylinder 20. In some examples, the membrane layer may cover both the outer sidewall and the inner sidewall of the heat-conducting cylinder 20.

[0052] Figure 2 This is a cross-sectional view of a heating assembly provided in an embodiment of this application, such as... Figure 2 As shown, multiple air intake channels 10a can be formed between the outer wall of the heat-conducting cylinder 20 and the inner wall of the heating cylinder 10, and the multiple air intake channels 10a are distributed around the heat-conducting cylinder 20.

[0053] As an example, the inner wall of the heating cylinder 10 has a plurality of first strip-shaped protrusions 11. The plurality of first strip-shaped protrusions 11 are distributed circumferentially along the heating cylinder 10 and extend along the length of the heating cylinder 10. The first strip-shaped protrusions 11 contact the outer wall of the heat-conducting cylinder 20, and adjacent first strip-shaped protrusions 11, the outer wall of the heat-conducting cylinder 20, and the inner wall of the heating cylinder 10 form an air intake channel 10a.

[0054] By providing a first strip-shaped protrusion 11 on the inner wall of the heating cylinder 10, and utilizing the contact between the first strip-shaped protrusion 11 and the outer wall of the heat-conducting cylinder 20, the heat from the heating cylinder 10 can be quickly conducted to the heat-conducting cylinder 20. Multiple first strip-shaped protrusions 11 are distributed circumferentially around the heating cylinder 10, allowing heat to be conducted more evenly to the heat-conducting cylinder 20, resulting in a more uniform temperature distribution and more even preheating of the air.

[0055] In some other possible implementations, the strip-shaped protrusions can also be arranged on the outer wall of the heat-conducting cylinder 20. For example, Figure 3 This is a cross-sectional view of a heating assembly provided in an embodiment of this application, such as... Figure 3 As shown, in this heating assembly, the outer wall of the heat-conducting cylinder 20 has a plurality of second strip-shaped protrusions 21. The plurality of second strip-shaped protrusions 21 are distributed circumferentially along the heat-conducting cylinder 20. The second strip-shaped protrusions 21 extend along the length direction of the heat-conducting cylinder 20. The second strip-shaped protrusions 21 contact the inner wall of the heating cylinder 10. Adjacent second strip-shaped protrusions 21, the outer wall of the heat-conducting cylinder 20, and the inner wall of the heating cylinder 10 form an air intake channel 10a.

[0056] The second strip-shaped protrusion 21 also enables a more uniform temperature distribution in the heat-conducting cylinder 20, resulting in more even preheating of the air. Furthermore, the difficulty of machining the strip-shaped protrusion differs between the heat-conducting cylinder 20 and the heating cylinder 10. Depending on the complexity of the machining process, the second strip-shaped protrusion 21 can be machined in the heat-conducting cylinder 20, or the first strip-shaped protrusion 11 in the heating cylinder 10, thereby reducing the complexity of the process and saving manufacturing costs.

[0057] Figure 4 This is a schematic diagram of the structure of a heating assembly provided in an embodiment of this application, such as... Figure 4 As shown, in some examples, the end of the heat-conducting cylinder 20 may abut against the closed end of the heating cylinder 10.

[0058] Since the heat-conducting cylinder 20 directly abuts against the end of the heating cylinder 10, during the assembly process, the heat-conducting cylinder 20 can be placed inside the heating cylinder 10 and pushed directly to the end of the heating cylinder 10, making assembly relatively convenient.

[0059] In some examples, the sidewall of the heat-conducting cylinder 20 may have multiple through holes 20a.

[0060] By providing a through hole 20a on the side wall of the heat-conducting cylinder 20, the air inlet channel 10a and the inner side of the heat-conducting cylinder 20 can be connected, so that the preheated air in the air inlet channel 10a can enter the heat-conducting cylinder 20, that is, enter the aerosol generating product located in the heat-conducting cylinder 20.

[0061] The through hole 20a can be located at the end of the heat-conducting cylinder 20 near the closed end of the heating cylinder 10, so that air can flow a sufficient distance in the air intake channel 10a, and prevent the air in the air intake channel 10a from entering the inside of the heat-conducting cylinder 20 before it is fully preheated.

[0062] As an example, multiple through holes 20a are arranged at intervals along the circumference of the heat-conducting cylinder 20, and the multiple through holes 20a are arranged in a one-to-one correspondence with multiple air intake channels 10a.

[0063] Figure 5 This is a schematic diagram of the structure of a heating assembly provided in an embodiment of this application, such as... Figure 5 As shown, in some other examples, the end of the heat-conducting cylinder 20 near the closed end of the heating cylinder 10 can be serrated. That is, the end of the heat-conducting cylinder 20 near the closed end of the heating cylinder 10 can have multiple notches 20b, which are distributed circumferentially along the heat-conducting cylinder 20. When the end of the heat-conducting cylinder 20 abuts against the closed end of the heating cylinder 10, the notches 20b can connect the air intake channel 10a and the inner side of the heat-conducting cylinder 20. The multiple notches 20b can be arranged one-to-one with the multiple air intake channels 10a.

[0064] There may also be a gap between the end of the heat-conducting cylinder 20 and the closed end of the heating cylinder 10, so that the air intake channel 10a can communicate with the inside of the heat-conducting cylinder 20 through the gap.

[0065] Figure 6 This is a schematic diagram of the structure of a heating assembly provided in an embodiment of this application, such as... Figure 6 As shown, the inner wall of the heating cylinder 10 has multiple support protrusions 12. The multiple support protrusions 12 are located at the closed end of the heating cylinder 10. Figure 7 This is a schematic diagram of the structure of a closed end of a heating cylinder provided in an embodiment of this application, as shown below. Figure 7 As shown, multiple support protrusions 12 are arranged at intervals along the circumference of the heating cylinder 10.

[0066] When the heated non-combustible device is in use, the aerosol generating product can be inserted into contact with the support protrusion 12. By providing the support protrusion 12, the end of the aerosol generating product can be prevented from completely adhering to the inner wall of the heating cylinder 10, allowing air to enter the aerosol generating product from the end of the aerosol generating product.

[0067] Reference Figure 1 As shown, the heating assembly also includes a heating element 30. The heating element 30 is located outside the heating cylinder 10 and is in contact with the outer surface of the heating cylinder 10.

[0068] The heating element 30 can be an electric heating element, which generates heat after being energized, thus raising the temperature of the heating cylinder 10. Placing the heating element 30 outside the heating cylinder 10 facilitates its arrangement. The contact between the heating element 30 and the outer surface of the heating cylinder 10 improves the efficiency of heat conduction, enabling the heating cylinder 10 to heat up rapidly.

[0069] Figure 8 This is a schematic diagram of the structure of a heating assembly provided in an embodiment of this application, as shown below. Figure 8 As shown, as an example, the heating cylinder 10 has a groove 10b on its exterior, the groove 10b being located on the end face of one closed end of the heating cylinder 10, and the heating element 30 being located in the groove 10b.

[0070] The heating element 30 is arranged in the groove 10b, which facilitates assembly and also provides protection for the heating element 30.

[0071] The heating element 30 can be a heating plate or a heating mesh. The heating element 30 can be fitted to the bottom of the groove 10b to improve the heat exchange efficiency between the heating element 30 and the heating cylinder 10.

[0072] like Figure 8 As shown, the heating assembly also includes a stop 40 located in the groove 10b. The stop 40 is located on the side of the heating element 30 away from the end face of the heating cylinder 10 to limit the displacement of the heating element 30 in the depth direction of the groove 10b.

[0073] By placing a stop 40 in the groove 10b to limit the heating element 30, the heating element 30 can be prevented from detaching from the groove 10b. When the heating element 30 is in contact with the bottom of the groove 10b, the stop 40 can also keep the heating element 30 in contact with the bottom of the groove 10b, avoiding gaps that would reduce heat exchange efficiency.

[0074] In some other possible implementations, the heating element 30 may also be arranged in other parts of the heating cylinder 10. Figure 9 This is a schematic diagram of the structure of a heating assembly provided in an embodiment of this application, as shown below. Figure 9 As shown, the heating element 30 is located on the outer wall of the heating cylinder 10, and the heating element 30 covers at least a portion of the outer wall of the heating cylinder 10.

[0075] Arranging the heating element 30 on the outer wall of the heating cylinder 10 helps to form a larger contact area between the heating element 30 and the heating cylinder 10, thereby improving heating efficiency.

[0076] As an example, the heating element 30 can be plated on the surface of the heating cylinder 10, so that the contact between the heating element 30 and the heating cylinder 10 is closer, and there is no need to set up other structures to limit the heating element 30.

[0077] In some possible implementations, the heating assembly may include two heating elements 30, one of which may be disposed at the end of the heating cylinder 10, for example... Figure 8 The arrangement of the heating element 30 shown allows for the placement of another heating element 30 on the outer wall of the heating cylinder 10, for example... Figure 9 The arrangement of the heating element 30 is shown.

[0078] Figure 10 This is a schematic diagram of the structure of a heating non-combustible device provided in an embodiment of this application, as shown below. Figure 10 As shown, the heated non-combustible device may include a housing 100 and, as shown, a... Figures 1-9 In any of the heating components shown, the housing 100 has a socket 100a, the heating component is located in the housing 100, and the heating cylinder 10 has an open end facing the socket 100a.

[0079] The heating non-combustible device may also include a power supply component located in the housing 100 and electrically connected to the heating component to supply power to the heating component.

[0080] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be included within the protection scope of this application.
