Description

Technical Field

[0001] This invention relates to the field of novel tobacco products, and in particular to a heat insulation structure used in heated cigarette devices. Background Technology

[0002] Heated tobacco products are devices that provide heat for heated cigarettes. Their function is to heat the atomized area of ​​the cigarette to a specific temperature through energy conversion, producing an aerosol for the consumer to inhale, but without combustion. Currently, common heated cigarette devices can be categorized based on their heating method, including inner core heating, outer perimeter heating, and combined heating.

[0003] The difficulty in making internal heating smoke appliances is:

[0004] 1. How to achieve better heat insulation, reduce the energy consumption of a single cigarette, and increase the number of cigarettes smoked.

[0005] 2. How to ensure proper heat dissipation and prevent the surface temperature of the casing from becoming too high directly affects the user experience. Conventional heat insulation or heat dissipation designs use either metal or non-metal materials. Metal casings conduct heat quickly, which helps dissipate heat, but they are not conducive to maximizing heat preservation and reducing energy consumption. Non-metal casings conduct heat slowly, which helps with heat insulation, but the local temperature will rise significantly, and the object may become too hot to hold. Summary of the Invention

[0006] This invention addresses the shortcomings of existing technologies by providing a combination of a plastic bracket and a metal bracket, which improves heat insulation while ensuring that localized heat accumulation and prevents burns. This heat insulation structure is suitable for use in heated cigarette devices.

[0007] To achieve the above objectives, the present invention first proposes a heat insulation structure for use in heated cigarette devices, comprising a cigarette holder tube, a second heat insulation component wrapped around the outside of the cigarette holder tube, a first heat insulation component wrapped around the outside of the second heat insulation component, and a heat dissipation component wrapped around the outside of the first heat insulation component. A gap is provided between the outer wall of the cigarette holder tube and the inner wall of the second heat insulation component to form a first heat insulation zone, and a gap is provided between the outer wall of the second heat insulation component and the inner wall of the first heat insulation component to form a second heat insulation zone. The inner wall of the heat dissipation component is in close contact with the outer wall of the first heat insulation component.

[0008] In this embodiment, the first heat insulation component includes a heat insulation base with a through hole in the middle. A limiting ring is fixed inside the through hole of the heat insulation base. The inner diameter of the central hole of the limiting ring matches the outer diameter of the bottom of the second heat insulation component. Four supporting ribs are fixed above the limiting ring, and multiple heat insulation legs are fixed below the heat insulation base. The four supporting ribs and multiple heat insulation legs are symmetrically arranged around the central axis of the limiting ring. The four supporting ribs enclose a first mounting area above the heat insulation base that matches the size of the second heat insulation component. The multiple heat insulation legs enclose a second mounting area below the heat insulation base that matches the external size of the electronic component module of the heated cigarette device. The second heat insulation component is installed in the first mounting area and is axially limited by the limiting ring.

[0009] In this embodiment, the upper inner diameter of the first installation area is larger than the outer diameter of the second heat insulation component, and a guide surface is provided on the lower side. The guide surface makes the bottom inner diameter of the first installation area match the bottom outer diameter of the second heat insulation component. The guide surface is formed by an inwardly inclined surface on the support ridge. After the second heat insulation component is inserted into the first installation area, the gap between the second heat insulation component and the support ridge forms the second heat insulation area.

[0010] In this embodiment, the heat insulation base has second screw holes on both sides, below the limiting ring, that match the mounting screw holes on the electronic component module.

[0011] In this embodiment, the second heat insulation component includes a cylindrical body with openings at the top and bottom. The cylindrical body has a cavity with an inner diameter larger than the outer diameter of the cigarette holder lifting tube. A first positioning edge extending radially and having an outer diameter larger than the outer diameter of the first installation area is fixed on the top outer wall of the cylindrical body. Two connecting ears are symmetrically installed on the bottom surface of the cylindrical body. The connecting ears have a third screw hole that matches the size of the second screw hole. After the cylindrical body is installed in the first installation area, the connecting ears are inserted into the second installation area through the through hole in the middle of the limiting ring, and the second screw hole on the connecting ear corresponds to the position of the second screw hole on the heat insulation seat.

[0012] In this embodiment, the cigarette holder lifting tube includes a cigarette tube body, which has a heating chamber inside. One end of the cigarette tube body is a smoke inlet, and the other end is a needle hole for inserting a heating needle into the heating chamber. A second positioning edge, which extends radially and has an outer diameter larger than that of the second heat insulation component, is fixed on the outer wall of the cigarette tube body near the smoke inlet. The cigarette holder lifting tube is inserted into the cavity of the second heat insulation component, and the needle hole of the cigarette holder lifting tube is connected to the lower opening of the cylinder.

[0013] In this embodiment, an upper magnet is fixed above the second positioning edge of the cigarette holder, and a lower magnet is fixed below the first positioning edge of the second heat insulation component. The cigarette holder is fixed inside the second heat insulation component by the connection of the upper and lower magnets.

[0014] In this embodiment, the heat sink includes a first housing and a second housing that are connected and fixed to each other. The first housing is positioned to match the first mounting area, and the second housing is positioned to match the second mounting area. The heat sink has a first screw hole at a position corresponding to the second screw hole. The heat sink, the first heat insulation component, and the second heat insulation component are fixed to the electronic component module by screws that pass through the first, second, and third screw holes in sequence.

[0015] In this embodiment, both the first and second heat insulation components are made of PC material, and the heat dissipation component is made of aluminum alloy.

[0016] In this embodiment, the thickness of the heat dissipation component is 0.6-0.8 mm, preferably 0.6 mm, and the thickness of the first heat insulation component and the second heat insulation component is 1.0-1.2 mm, preferably 1.1 mm.

[0017] With the above structure, the present invention has the following advantages:

[0018] 1. Utilizing the principle that aluminum conducts heat quickly while plastic parts conduct heat slowly, on the one hand, since the cigarette holder is the heat source, heat insulation is achieved by setting up two layers of heat-resistant protection in the area where the cigarette holder is located, namely the first and second heat-resistant insulation components. At the same time, two partitions are set up to form the first and second heat-resistant insulation zones, thereby effectively utilizing air for heat insulation and minimizing the transfer of heat from the cigarette holder to the outside through the first and second heat-resistant insulation components. On the other hand, a heat dissipation component is wrapped around the first heat-resistant insulation component, thereby quickly conducting the heat dissipation component to the outside of the first heat-resistant insulation component and evenly covering the entire heat dissipation component, avoiding heat concentration and reducing the surface temperature of the heat dissipation component in the area where the cigarette holder is located. The heat dissipation component ensures the reliability of the support strength of the device while preventing local overheating of the heated cigarette device, and at the same time, it helps to improve the heat preservation efficiency of the cigarette wrapping area, reduce the energy consumption of a single cigarette, and improve the battery life.

[0019] 2. The cigarette holder and the cigarette holder lifting tube are assembled together by the lower magnet and the upper magnet through magnetic force, which makes it more convenient to replace the cigarette holder and the cigarette holder lifting tube.

[0020] 3. The multiple support ridges of the first heat insulation component form the first installation area, and the first installation area formed by the support ridges is also the heat insulation area. Specifically: the support ridges are provided with guide surfaces. After the second heat insulation component is installed in the first installation area, the bottom of the second heat insulation component slides into the first installation area through the guide surfaces, thereby controlling the landing point of the second heat insulation component and ensuring its installation accuracy. At the same time, the gaps between the second heat insulation component and the support ridges, as well as between the second heat insulation component and the heat dissipation component, form the second heat insulation area, and the air in the gaps is used for further heat insulation and heat preservation.

[0021] 4. The heat sink, the first heat insulation component, and the second heat insulation component are fixed to the electronic component module by screws that pass through the first, second, and third screw holes in sequence. This connection method makes the connection of the three components convenient and stable, ensures the accurate position of each heat insulation cavity, and facilitates the disassembly and maintenance of the equipment.

[0022] In summary, this device, by disassembling the support into multiple parts, forms a unique stacked structure. Heat insulation and heat dissipation components are used in different parts, which ensures both heat insulation and heat dissipation of the outer shell. This achieves the technical effect of improving heat insulation while ensuring that local heat accumulation and heat dissipation are not achieved, thus solving the problems existing in the prior art.

[0039] The heated cigarette device includes an electronic component module 10, a heating needle 6 mounted on the electronic component module 10, and a housing 1.

[0040] like Figure 5 , 8As shown in Figure 9, the first heat insulation component 3 includes a horizontally arranged heat insulation base 33. A through hole is provided in the center of the heat insulation base 33. A limiting ring 36 is fixed inside the through hole of the heat insulation base 33. The inner diameter of the central hole of the limiting ring 36 is slightly smaller than the outer diameter of the bottom of the second heat insulation component 4, so that the bottom of the second heat insulation component 4 is inserted into the central hole of the limiting ring 36 for limiting.

[0041] Four vertically arranged support ribs 32 are fixed above the limiting ring 36, and two vertically arranged heat-insulating legs 34 are fixed below the heat insulation seat 33. The four support ribs 32 and the two heat-insulating legs 34 are symmetrically arranged around the central axis of the limiting ring 36. The four support ribs 32 enclose a first mounting area 35 above the heat insulation seat 33, which matches the size of the second heat insulation component 4. The two heat-insulating legs 34 enclose a second mounting area 37 below the heat insulation seat 33, which matches the external size of the electronic component module 10. The electronic component module 10 is disposed in the second mounting area 37. The upper inner diameter of the first mounting area 35 is larger than the outer diameter of the second heat insulation component 4, and a guide surface 39 is provided on the lower side. The guide surface 39 makes... The bottom inner diameter of the first mounting area 35 matches the bottom outer diameter of the second heat insulation component 4. The guide surface 39 is formed by an inwardly inclined surface on the support rib 32. When the second heat insulation component 4 is installed in the first mounting area 35, under the guidance of the guide surface 39, the second heat insulation component 4 can accurately fall into the first mounting area 35. The bottom of the second heat insulation component 4 is inserted into the center hole of the limiting ring 36 to achieve axial limiting. At the same time, the gap between the second heat insulation component 4 and the support rib 32 forms the second heat insulation area 9 (the width of the second heat insulation area 9 is about 1mm). The heat insulation seat 33 has second screw holes 38 on both sides and below the limiting ring 36 that match the mounting screw holes on the electronic component module 10.

The cylindrical body 42 has a cavity with an inner diameter larger than the outer diameter of the cigarette holder lifting tube 5. A first positioning edge 41, extending radially along the cylindrical body 42 and having an outer diameter larger than the outer diameter of the first mounting area 35, is fixed on the top outer wall of the cylindrical body 42. A lower magnet 31 (in this embodiment, the lower magnet 31 is a magnetic ring, which is fitted onto the outside of the cylindrical body 42 and fixed to the first positioning edge 41) is fixed below the first positioning edge 41. The bottom surface of the cylindrical body 42... Two connecting ears 44 are symmetrically installed. Each connecting ear 44 has a third screw hole 45 that matches the size of the second screw hole 38. After the cylindrical body 42 is installed in the first mounting area 35, the first positioning edge 41 of the cylindrical body 42 and the lower magnet 31 are supported on the top of the four supporting ridges 32. The bottom of the cylindrical body 42 is set in the central hole of the limiting ring 36. The connecting ear 44 is inserted into the second mounting area 37 from the central hole of the limiting ring 36, so that the second screw hole 38 on the connecting ear 44 corresponds to the second screw hole 38 on the heat insulation seat 33.

[0043] like Figure 7 As shown, the cigarette holder lifting tube 5 includes a tube body 52. ​​The tube body 52 has a heating chamber that matches the size of the cigarette 7. One end of the tube body 52 is a smoke inlet, and the other end is a needle hole 53 for inserting a heating needle 6 into the heating chamber. A second positioning edge 54, extending radially along the tube body 52 and having an outer diameter larger than the outer diameter of the second heat insulation component 4, is fixed on the outer wall of the tube body 52 near the smoke inlet. An upper magnet 51, matching the lower magnet 31, is fixed above the second positioning edge 54 (in this embodiment, the upper magnet 51 is also a magnetic ring, fitted onto the outside of the tube body 52 and fixed to the second positioning edge 54). The cigarette holder lifting tube 5 is inserted into the second heat insulation component. Inside the cavity of 4, there is a gap between the outer wall of the cigarette holder 5 and the inner wall of the second heat insulation component 4 to form a first heat insulation area 8 (the width of the first heat insulation area 8 is smaller than the width of the second heat insulation area 9; in this embodiment, the first heat insulation area 8 is 0.28-0.30 mm). The second positioning edge 54 of the cigarette holder 5 is supported on the first positioning edge 41, and under the magnetic attraction of the upper and lower magnets, the outer wall of the cigarette holder 5 is fixed and positioned to the second heat insulation component 4. At the same time, the needle hole 53 of the cigarette holder 5 is connected to the lower opening 43 of the cylinder 42. When the electronic component module 10 is installed in the second installation area 37, the heating needle 6 passes through the lower opening 43 and the needle hole 53 in sequence and is placed in the heating cavity.

[0044] like Figure 4As shown, the heat sink 2 includes a first housing 21 and a second housing 22 that are connected and fixed to each other and have interconnected cavities. The first housing 21 is positioned to match the first mounting area 35, and the second housing 22 is positioned to match the second mounting area 37. After the heat sink 2 is fitted over the first heat insulation component 3, the inner wall of the first housing 21 contacts the outer wall of the support ridge 32 and the heat insulation seat 33, and completely covers the support ridge 32 and the heat insulation seat 33.
