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] Heated non-combustible devices are electronic devices that release nicotine and flavor compounds by heating rather than burning an aerosol-generating matrix. The core principle is to heat a specially formulated aerosol-generating matrix at a temperature lower than that of traditional cigarettes, thus avoiding the production of a large number of harmful combustion byproducts.

[0003] The heating element is one of the core components of a heated non-combustible device. In existing technologies, the heating element is typically made of ceramics, metals, or composite materials, all of which have excellent thermal conductivity. The heating element is usually placed inside an insulation cavity and is often in contact with it. To achieve better insulation, some insulation cavities are made of PEEK (polyether ether ketone). If the heating temperature of the heating element is too high, part of the insulation cavity may melt, thereby damaging the electronic atomization device. Utility Model Content

[0025] Example 1

[0026] This application provides a heating non-combustible device 100, please refer to... Figure 1-5The heated non-combustible device 100 includes a housing 110, an inner housing 120 located within the housing 110, a heat insulation element 130, and a heating element 140.

[0027] Please refer to Figure 1-4 The housing 110 has an insertion port 111. An inner shell 120 located within the housing 110 has a receiving cavity 121. The receiving cavity 121 has an air outlet 1211, which is positioned facing and communicating with the insertion port 111. A heat insulation element 130 is disposed at the air outlet 1211. A heating element 140 is disposed within the receiving cavity 121, extending from the interior of the receiving cavity 121 to the air outlet 1211 and fitting against the side of the heat insulation element 130 facing away from the cavity 121. The heating element 140 has a heating chamber 141 for inserting an aerosol generating matrix to heat the aerosol generating matrix.

[0028] In this application, the inner shell 120 is disposed within the outer shell 110, and the inner shell 120 is provided with a receiving cavity 121. The receiving cavity 121 has an air outlet 1211. By disposing of the heat insulation member 130 at the air outlet 1211, and in this application, the material of the inner shell 120 is polyetheretherketone (PEEK), the inner shell 120 is indirectly in contact with the heating element 140, which can avoid the problem of the inner shell 120 cavity wall being melted due to direct contact between the cavity wall of the inner shell 120 and the heating element 140.

[0029] Please refer to Figure 5 In this embodiment, the heat insulation component 130 includes a first top wall 131 and a first side wall 132. The top wall 131 separates the inner shell 120 and the heating element 140 in the air outlet direction of the air outlet 1211, and the first side wall 132 separates the inner shell 120 and the heating element 140 in the air outlet direction perpendicular to the air outlet 1211. The thickness of the top wall 131 along the air outlet direction of the air outlet 1211 is h1, and the thickness of the first side wall 132 along the air outlet direction perpendicular to the air outlet 1211 is h2, where h1 > h2.

[0030] In this embodiment, the top wall 131 is in direct contact with the heating element 140 and the cavity wall of the inner shell 120 on both sides, respectively. To prevent the heating element 140 from melting the cavity wall of the inner shell 120, the first top wall 131 needs to have a certain thickness. Meanwhile, the heat around the heating element 140 needs to be dissipated in a timely manner. While ensuring that the heating element 140 does not melt the cavity wall of the inner shell 120 in the lateral direction, it needs to be as thin as possible. Therefore, in this embodiment, the thickness h1 of the first top wall 131 needs to be greater than the thickness of the first side wall 132. More specifically, in this embodiment, 0.6 ≤ h1 ≤ 1.5 mm, 0.6 ≤ h2 ≤ 1.0 mm.

[0031] Please refer to Figure 2The sidewall of the heating element 140 and the sidewall of the inner shell 120 define a heat insulation cavity 1212. The heat insulation component 130 is also provided with heat dissipation holes 1321, which are located inside the heat insulation cavity 1212.

[0032] The heat dissipation hole 1321 is provided on the heat insulation component 130, which helps to reduce the heat transferred from the heat insulation component 130 to the cavity wall of the inner shell 120. Furthermore, the heat dissipation hole 1321 is provided in the part of the heat insulation component 130 located in the heat insulation cavity 1212. On the one hand, it helps to dissipate heat from the heat-generating component and avoids melting the cavity wall of the inner shell 120. On the other hand, it can realize heat recovery, so that the heat insulation cavity 1212 has a certain amount of heat to maintain the temperature inside the heating cavity 141.

[0033] Please refer to Figure 4 The air outlet 1211 is also evenly provided with multiple positioning elements 122, which are used to fix the heat insulation element 130.

[0034] In this embodiment, by spaced out the positioning members 122 at the air outlet 1211, the heat transferred from the heat insulation member 130 to the side wall of the inner shell 120 can be reduced. More specifically, the number of positioning members 122 is 4.

[0035] Please refer to Figure 4 In this embodiment, a limiting flange 1213 is provided at one end of the accommodating cavity 121 located at the air outlet 1211. The limiting flange 1213 is used to limit the heat insulation member 130 and the heating element 140. The portion of the limiting flange 1213 facing the accommodating cavity 121 protrudes and extends into the accommodating cavity 121 to form a positioning member 122. The positioning member 122 is spaced apart from the cavity wall inside the accommodating cavity 121. The positioning space formed by the heat insulation member 130 and the multiple positioning members 122 is interference-fitted.

[0036] A positioning space is formed by multiple positioning elements 122. Since the cavity material of the inner shell 120 is PEEK, the heat insulation element 130 can be interference-fitted with the positioning space, which achieves the purpose of fixing the heat insulation element 130 and also facilitates disassembly.

[0037] Please refer to Figure 2-3 The heating non-combustible device 100 also includes a base 150, which is located at one end of the accommodating cavity 121 away from the gas outlet 1211, and is used to support the heating element 140.

[0038] In this application, since the heating temperature of the end of the heating element 140 near the air outlet 1211 is higher than the heating temperature of the end near the base 150, the heat insulation element 130 does not need to be provided in the part that contacts the base 150.

[0039] To further seal the heating chamber 141, please refer to... Figure 2A first sealing element 160 is provided at the contact position between the base 150 and the heating element 140.

[0040] Please refer to Figure 2 and Figure 5 The first top wall 131 and the first side wall 132 on the heat insulation component 130 define the first retaining step 133. When the heat insulation component 130 is installed on the air outlet 1211, the first retaining step 133 is set away from the positioning component 122. The first retaining step 133 forms a first retaining space. One end of the heating element 140 is supported on the base 150, and the other end extends into the first retaining space and is interference-fitted with the first retaining space.

[0041] Please refer to Figure 2 The heating non-combustible device 100 also includes a bracket 170, which is disposed inside the housing 110. The bracket 170 and the inner cavity of the housing 110 define a first installation space 171 and a second installation space. The inner shell 120 is disposed in the first installation space 171 and supported by the bracket 170.

[0042] Please refer to Figure 2 The heated non-combustible device 100 also includes a circuit board 180, which is electrically connected to the heating element 140. The flow direction of the aerosol at the air outlet 1211 is the first axial direction. The circuit board 180 is disposed in the second mounting space in a direction parallel to the first axial direction and defines a power supply 190 mounting cavity 172 with the bracket 170. The power supply 190 mounting cavity 172 is used to accommodate the power supply 190.

[0043] Please refer to Figure 2 The heated non-combustible device 100 also includes a button 200, which is disposed on and electrically connected to the circuit board 180, and the button 200 is at least partially exposed outside the housing 110, for starting or stopping the heated non-combustible device 100.

[0044] Please refer to Figure 2 The bottom of the housing 110 is provided with an air inlet 112 for drawing in air.

[0045] Please refer to Figure 2-3 The heating non-combustible device 100 also includes a clamping member 210, which is disposed inside the housing 110 and located between the gas outlet 1211 and the insertion port 111. The inner side wall of the clamping member 210 is provided with a clamping protrusion 211. The diameter of the clamping space formed by the clamping protrusion 211 is smaller than the diameter of the aerosol generating matrix. Thus, when the aerosol generating matrix is ​​inserted into the heating chamber 141 through the insertion port 111, the clamping protrusion 211 can clamp the aerosol generating matrix and prevent the aerosol generating matrix from falling off.

[0046] In other embodiments, the heated non-combustible device 100 also includes a dust cover (not shown) movably disposed on the housing 110 to open or close the insertion port 111.

[0047] In this embodiment, the inner shell 120 has an air inlet (not shown), which is connected to the air inlet 112 for drawing in air.

[0048] In addition, the heated non-combustible device 100 also includes an airflow sensor (not shown), which is disposed in the air path between the air inlet and the air inlet 112 and is used to sense the suction action.
