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

[0016] In some examples, the heat-conducting element includes a plurality of heat-conducting tubes arranged around the heating cylinder on the outer wall of the heating cylinder, and the air intake channel includes the lumen of the heat-conducting tubes.

[0017] In some examples, the heat pipe extends spirally along the axial direction of the heating cylinder.

[0018] In some examples, the heating element has a baffle on the outside of its opening, and the baffle has multiple air inlets;

[0020] In some examples, the wall of the heating element has multiple through holes that communicate with the air intake channel.

[0021] In some examples, the inner wall of the heating element has a limiting protrusion located on the side of the plurality of through holes near the opening of the heating element.

[0022] In some examples, the heating element wall also has an air guide groove, one end of which is located on the inner side wall of the heating element and communicates with the through hole, and the other end is located on the inner end face of the heating element.

[0023] 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.

[0047] Figure 1 This is a schematic diagram of the structure of a heating assembly provided in an embodiment of this application, as shown below. Figure 1 As shown, the heating assembly includes a heating cylinder 10 and a heat-conducting element 20. One end of the heating cylinder 10 has an opening and the other end is closed. The heat-conducting element 20 is located outside the heating cylinder 10.

[0048] The heating assembly has an air inlet channel 10a, which communicates with the inside of the heating cylinder 10. The air inlet channel 10a is formed at at least one of the following locations:

[0049] Between the outer wall of the heating cylinder 10 and the heat-conducting element 20;

[0050] In the heat-conducting component 20.

[0051] By providing an opening at one end of the heating cylinder 10, the aerosol-generated product can be inserted into the heating cylinder 10 for heating during use. A heat-conducting element 20 is provided outside the heating cylinder 10, and the air inlet channel 10a of the heating assembly is formed at least between the outer wall of the heating cylinder 10 and the heat-conducting element 20, or within the heat-conducting element 20. The air inlet channel 10a is connected to the inner side of the heating cylinder 10. During the suction process, outside air enters the air inlet channel 10a and can be heated by the heating cylinder 10 or the heat-conducting element 20. The provision of the air inlet channel 10a increases the airflow path within the heating assembly. Preheating using the heating cylinder 10 and the heat-conducting element 20 does not require increasing the size of the heating cylinder 10, and the mass of the heating assembly only increases the mass of the heat-conducting element 20. This small increase in mass has minimal impact on heat melting, allowing for preheating of air without significantly affecting heating time and energy consumption.

[0052] The heating element 10 can be made of metal or non-metal materials.

[0053] For example, the heating element 10 may be made of at least one of aluminum, magnesium, copper, aluminum alloy, magnesium alloy, and copper alloy.

[0054] For example, the heating element 10 can also be made of graphite.

[0055] The heat-conducting component 20 can be made of a metallic material, such as metal foil. The metal foil is very thin, thus having a minimal impact on the overall mass of the heating assembly and its heat capacity.

[0056] For example, the heat-conducting element 20 may be made of aluminum foil.

[0057] The mass of the heat-conducting component 20 can be 0.01 g to 0.3 g, for example, the mass of the heat-conducting component 20 can be 0.2 g.

[0058] The heat-conducting element 20 can be connected to the outer wall of the heating cylinder 10 to promote heat exchange between the heating cylinder 10 and the heat-conducting element 20.

[0059] For example, the heat-conducting element 20 and the heating cylinder 10 can be connected by ultrasonic welding or hot pressing.

[0060] In some examples, the surface of the heat-conducting element 20 may be covered with a film layer, including at least one of a silver layer and an infrared coating.

[0061] A film layer is applied to the surface of the heat-conducting component 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 component 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 and thus has a high emissivity. During the operation of the heating assembly, this can enhance the heat-conducting component 20's ability to generate outward thermal radiation, thereby better preheating the air and better transferring heat to the aerosol-generated product.

[0062] like Figure 1 As shown, the heat-conducting component 20 is cylindrical and is fitted over the heating cylinder 10.

[0063] By sleeved around the heating cylinder 10, the area for heat exchange between the heat-conducting element 20 and the heating cylinder 10 is larger, which is beneficial for heat exchange between the heating cylinder 10 and the heat-conducting element 20. During the operation of the heating assembly, the heat-conducting element 20 can heat up more quickly and the temperature distribution is more uniform.

[0064] Figure 2 This is a schematic diagram of the structure of a heating assembly provided in an embodiment of this application. Figure 2 At least part of the structure of the heat-conducting component 20 has been removed, such as Figure 2 As shown, in some examples, the air intake passage 10a includes a gap between the outer wall of the heating cylinder 10 and the inner wall of the heat conductor 20.

[0065] A cylindrical heat-conducting element 20 is fitted over the heating cylinder 10, forming an annular gap between the heat-conducting element 20 and the heating cylinder 10. This gap serves as an air inlet channel 10a, allowing air to contact the outer wall of the heating cylinder 10 and the inner wall of the heat-conducting element 20 as it flows through, thus being heated by both. The large contact area between the air and the heating components ensures sufficient preheating even with a high airflow rate, improving the preheating effect.

[0066] Figure 3 This is a schematic diagram of the structure of a heat-conducting component provided in an embodiment of this application. Figure 3 At least some parts of the structure of the heat-conducting component 20 are omitted, such as Figure 3 As shown, as an example, the heat-conducting component 20 includes a cylindrical main body portion 21 and a cylindrical connecting portion 22, wherein the inner diameter of the cylindrical main body portion 21 is larger than the inner diameter of the cylindrical connecting portion 22. One end of the cylindrical main body portion 21 is connected to one end of the cylindrical connecting portion 22, and the inner sidewall of the cylindrical connecting portion 22 is in contact with the outer sidewall of the heating cylinder 10.

[0067] The inner wall of the cylindrical main body 21 and the outer wall of the heating cylinder 10 form an air intake channel 10a. The cylindrical connecting part 22 fits snugly against the outer wall of the heating cylinder 10 to ensure sealing and prevent leakage from the air intake channel 10a. Furthermore, the cylindrical connecting part 22's fit against the outer wall of the heating cylinder 10 facilitates heat exchange between the heating cylinder 10 and the heat-conducting element 20, enabling the heat-conducting element 20 to heat up rapidly during the operation of the heating assembly. Since the cylindrical connecting part 22 is fitted over the heating cylinder 10, the temperature of different areas of the heat-conducting element 20 can rise uniformly in the circumferential direction.

[0068] In some examples, the cylindrical connector 22 can be thermo-pressed or ultrasonically welded to the heating element 10. Thermo-pressing and ultrasonic welding can create a good seal between the cylindrical connector 22 and the heating element 10.

[0069] Figure 4 This is a schematic diagram of the structure of a heat-conducting component provided in an embodiment of this application, compared to... Figure 3 The heat-conducting component 20 shown is, for example Figure 4 As shown, the inner wall of the heat-conducting component 20 may also be connected with multiple partitions 212, which are distributed around the heating cylinder 10 and extend along the axial direction of the heat-conducting component 20.

[0070] The baffle 212 divides the air intake channel 10a into multiple narrow channels. During the suction process, air flows through these narrow channels, and the baffle 212 restricts the airflow direction, preventing turbulence within the air intake channel 10a and ensuring thorough and uniform preheating of the air. Furthermore, the baffle 212 increases the contact area between the air in the air intake channel 10a and the heating element, allowing some heat to be transferred to the air via the baffle 212, further enhancing the preheating effect.

[0071] As an example, the partition 212 can be spiral-shaped.

[0072] Spiral baffles 212 extend spirally outside the heating cylinder 10. Multiple baffles 212 divide the air intake channel 10a into multiple spiral channels, which can extend the path of air flow through the air intake channel 10a, thereby allowing the air to be preheated more fully.

[0073] like Figure 2 As shown, the heating cylinder 10 has a baffle 11 on the outer side of its opening, and the baffle 11 has multiple air inlets 11a. The heat-conducting element 20 is located on one side of the baffle 11, and the air inlet channel 10a communicates with the air inlets 11a.

[0074] When assembling the heat-conducting component 20 and the heating cylinder 10, the retaining edge 11 can limit the heat-conducting component 20, making it easier to assemble the heat-conducting component 20 into place. The retaining edge 11 can be sealed to the heat-conducting component 20.

[0075] like Figure 3 As shown, the heat-conducting element 20 may have an outer flange 211. The outer flange 211 may be located at the opening at one end of the cylindrical body portion 21 away from the cylindrical connecting portion 22. The outer flange 211 is fitted with the flange 11. Exemplarily, the outer flange 211 and the flange 11 may be connected by hot pressing or ultrasonic welding.

[0076] The outer diameter of the outer flange 211 can be the same as the outer diameter of the baffle 11, so as to prevent the outer flange 211 from protruding from the baffle 11, and to make the contact area between the outer flange 211 and the baffle 11 larger, so that the heat-conducting element 20 and the heating cylinder 10 are tightly connected.

[0077] Air inlets 11a are distributed on the inner side of the cylindrical main body 21. In some examples, multiple air inlets 11a are circumferentially distributed, and the inner diameter of the cylindrical main body 21 is larger than the diameter of the circumference of the distribution of multiple air inlets 11a.

[0078] Figure 5 This is a schematic diagram of the structure of a heat-conducting component provided in an embodiment of this application, as shown below. Figure 5 As shown, in some possible implementations, the heat-conducting element 20 may have an inner flange 213, which may be located at the opening of the cylindrical body portion 21 away from the cylindrical connecting portion 22. The inner flange 213 is fitted with the flange 11. Exemplarily, the inner flange 213 and the flange 11 may be connected by thermoforming or ultrasonic welding.

[0079] In some examples, the inner diameter of the inner flange 213 can be the same as the outer diameter of the heating element 10, which helps to maximize the contact area between the inner flange 213 and the flange 11.

[0080] The inner flange 213 may have a clearance structure at the position corresponding to the air inlet 11a, such as a first clearance hole 213a, a notch, etc., to prevent the inner flange 213 from blocking the air inlet 11a.

[0081] The outer diameter of the cylindrical main body 21 can be the same as the outer diameter of the baffle 11, so that the gap between the inner wall of the cylindrical main body 21 and the outer wall of the heating cylinder 10 is larger, the air resistance is smaller, which is conducive to the air flow and avoids the gap being too small, which would affect the air flow and cause excessive resistance during suction.

[0082] In other examples, the inner flange 213 may be located outside the plurality of air inlets 11a. For example, the inner diameter of the inner flange 213 is larger than the diameter of the circumference of the distribution of the plurality of air inlets 11a, thus eliminating the need for a first clearance hole 213a in the inner flange 213.

[0083] like Figure 2 As shown, the wall of the heating cylinder 10 has multiple through holes 10b, which are connected to the air inlet channel 10a.

[0084] Multiple through holes 10b can be located close to the closed end of the heating cylinder 10, meaning the distance from the through hole 10b to the opening of the heating cylinder 10 is greater than the distance from the through hole 10b to the inner end face of the heating cylinder 10. One end of the heating cylinder 10 is closed. The inner end face of the heating cylinder 10 refers to the surface inside the heating cylinder 10 that is connected to the inner sidewall of the heating cylinder 10, and this surface is opposite to the end face of the closed end of the heating cylinder 10.

[0085] By setting multiple through holes 10b to connect the air intake channel 10a and the inner side of the heating cylinder 10, air can enter the heating cylinder 10 from multiple directions, making the airflow more stable.

[0086] As an example, multiple through holes 10b are arranged at equal angles along the circumference of the heating cylinder 10, which can make the airflow more stable and the air velocity in different positions of the heating cylinder 10 in the air intake channel 10a is relatively consistent, so that the air in different positions can be preheated evenly.

[0087] Figure 6 This is a schematic diagram of the internal structure of a heating cylinder according to an embodiment of this application. At least a portion of the cylinder wall of the heating cylinder 10 has been removed from the diagram. Figure 6 As shown, the inner wall of the heating cylinder 10 has a limiting protrusion 12. The limiting protrusion 12 is located on the side of the plurality of through holes 10b near the opening of the heating cylinder 10.

[0088] When using the heated non-combustible device, the aerosol generating product is inserted into the heating cylinder 10. The limiting protrusion 12 can limit the aerosol generating product to prevent it from being inserted too far and blocking the through hole 10b of the heating cylinder 10 wall, thus affecting the airflow.

[0089] As an example, the limiting protrusion 12 can be annular.

[0090] The limiting protrusion 12 can be fixedly connected to the cylinder wall of the heating cylinder 10, for example, the limiting protrusion 12 is integrally formed with the cylinder wall of the heating cylinder 10. The limiting protrusion 12 can also be detachably connected to the cylinder wall of the heating cylinder 10, for example, the inner wall of the heating cylinder 10 can have a groove, and the limiting protrusion 12 can be locked in the groove.

[0091] Figure 7 This is a schematic diagram of a heating cylinder provided in an embodiment of this application. At least a portion of the cylinder wall of the heating cylinder 10 has been removed from the diagram. Figure 7 As shown, the heating cylinder 10 has an air guide groove 10c on its cylinder wall. One end of the air guide groove 10c is located on the inner side wall of the heating cylinder 10 and communicates with the through hole 10b; the other end of the air guide groove 10c is located on the inner end face of the heating cylinder 10.

[0092] By providing the air guide groove 10c, even if the aerosol generating product blocks the through hole 10b of the heating cylinder 10 wall, the air in the through hole 10b can still flow through the air guide groove 10c to the end face of the aerosol generating product and enter the aerosol generating product.

[0093] 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.

[0094] 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.

[0095] 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 10d on its outside, the groove 10d is located on the end face of one closed end of the heating cylinder 10, and the heating element 30 is located in the groove 10d.

[0096] The heating element 30 is arranged in the groove 10d, which facilitates assembly and also provides protection for the heating element 30.

[0097] 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 10d to improve the heat exchange efficiency between the heating element 30 and the heating cylinder 10.

[0098] like Figure 8 As shown, the heating assembly also includes a stop 40 located in the groove 10d. The stop 40 is located on the side of the heating element 30 away from the end face of the heating cylinder 10, so as to limit the displacement of the heating element 30 in the depth direction of the groove 10d.

[0099] By arranging a stop 40 in the groove 10d to limit the heating element 30, the heating element 30 can be prevented from detaching from the groove 10d. When the heating element 30 is in contact with the bottom of the groove 10d, the stop 40 can also keep the heating element 30 in contact with the bottom of the groove 10d, avoiding gaps that would reduce heat exchange efficiency.

[0100] 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.

[0101] Arranging the heating element 30 on the outer wall of the heating cylinder 10 facilitates a larger contact area between the heating element 30 and the heating cylinder 10, thereby improving heating efficiency. Furthermore, the heating element 30 located on the outer wall of the heating cylinder 10 can directly heat the airflow in the air intake channel 10a, resulting in faster air preheating.

[0102] 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.

[0103] 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.

[0104] Figure 10 This is a schematic diagram of the structure of a heat-conducting component provided in an embodiment of this application, as shown below. Figure 10 As shown, the heat-conducting component 20 has a hollow structure. The heat-conducting component 20 includes a first cylindrical body 23 and a second cylindrical body 24. The first cylindrical body 23 is fitted over the heating cylinder 10, and the second cylindrical body 24 is fitted over the first cylindrical body 23. The air inlet channel 10a includes a gap between the outer wall of the first cylindrical body 23 and the inner wall of the second cylindrical body 24.

[0105] In this example, since the air intake channel 10a is formed in the heat-conducting element 20, the sealing requirements between the heat-conducting element 20 and the heating cylinder 10 are relatively low.

[0106] Among some possible implementations, Figure 10 The heat-conducting component 20 shown may further include multiple partitions 212 connected between the first cylinder 23 and the second cylinder 24, dividing the annular gap between the first cylinder 23 and the second cylinder 24 into multiple elongated channels. The partitions 212 may also be spiral-shaped. The function of the partitions 212 between the first cylinder 23 and the second cylinder 24 is... Figure 4 The partition 212 serves the same purpose in the example shown.

[0107] like Figure 10 As shown, the heat-conducting component 20 may further include a first annular plate 25, which is sleeved around the heating cylinder 10 and located at the end of the first cylinder 23 away from the opening of the heating cylinder 10. The first annular plate 25 connects the first cylinder 23 and the second cylinder 24 to seal the air intake passage 10a.

[0108] The heat-conducting component 20 may further include a second annular plate 26, which is sleeved around the heating cylinder 10 and located at the end of the first cylinder 23 near the opening of the heating cylinder 10. The second annular plate 26 connects the first cylinder 23 and the second cylinder 24. The second annular plate 26 may be connected to the flange 11 of the heating cylinder 10. A second clearance hole 26a may be provided on the second annular plate 26 corresponding to the air inlet hole 11a on the flange 11 to keep the air inlet hole 11a in communication with the air inlet channel 10a.

[0109] In some other possible implementations, the heat-conducting element 20 may not include the second annular plate 26, and the end of the first cylinder 23 near the opening of the heating cylinder 10 and the end of the second cylinder 24 near the opening of the heating cylinder 10 may be connected to the baffle 11 of the heating cylinder 10. By directly connecting the first cylinder 23 and the second cylinder 24 to the baffle 11, the amount of material used can be reduced, which is beneficial to reducing the weight of the heating assembly.

[0110] Figure 11 This is a schematic diagram of the structure of a heating assembly provided in an embodiment of this application, as shown below. Figure 11 As shown, in this example, the heat-conducting component 20 includes a plurality of heat-conducting pipes 27, which are arranged around the outer wall of the heating cylinder 10. The air inlet channel 10a includes the lumen of the heat-conducting pipes 27.

[0111] Using the cavity of multiple heat-conducting pipes 27 as the air intake channel 10a, the volume and weight of the heat-conducting component 20 are relatively small, which is beneficial to reducing the weight of the heating component.

[0112] In some possible implementations, the heat pipe 27 may extend spirally along the axial direction of the heating cylinder 10.

[0113] By setting a spirally extended heat pipe 27, the heat pipe 27 can be made longer, and the airflow path in the air intake channel 10a is longer, which is beneficial to improving the preheating effect of the air.

[0114] Figure 12 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 12 As shown, the heated non-combustible device may include a housing 100 and, as shown, a... Figures 1 to 11 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.

[0115] 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.

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.
