Description

Technical Field

[0001] The utility model relates to the technical field of heating without burning, in particular to a heating component and a heating without burning device. Background Art

[0002] In order to overcome the harmful substances produced by cigarette combustion, cigarette substitutes such as heat-not-burn devices have emerged. By placing an aerosol-generating substrate in a heat-not-burn device, smoke for inhalation is formed under heating without burning.

[0003] There are two main heating methods for heat-not-burn devices: central heating and peripheral heating. In the central heating method, the heating needle is inserted into the aerosol generating matrix to heat the aerosol generating matrix; in the peripheral heating method, the aerosol generating matrix is ​​located inside the heat-conducting cavity, and the heating element first heats the heat-conducting cavity, and then transfers the heat to the aerosol generating matrix through the heat-conducting cavity. However, the heat dissipation of the heating element is more serious when the energy of the heating element is transferred to the aerosol generating matrix through the heat-conducting cavity. In addition, since the heat-conducting cavity is generally fixed to the inside of the heat-not-burn device by other components, the heat of the heat-conducting cavity is also easily dissipated to the outside through other components, resulting in serious energy loss. Utility Model Content

[0004] The purpose of the present application is to provide a heating component and a heat-without-combustion device to solve the problem of serious energy loss in the heating device in the prior art, thereby reducing the power consumption of the heat-without-combustion device.

[0015] Alternatively, the limiting portion is a point-shaped protrusion arranged on the heating element, and the bottom of the airflow heating device is fixed on the point-shaped protrusion.

[0016] The present application also provides a heating without burning device, comprising:

[0017] A housing, wherein a mounting seat is provided in the housing, and the mounting seat accommodates and mounts an aerosol-forming substrate;

[0018] The heating component as described in any of the above embodiments is arranged in the shell, the heating element partially extends into the interior of the mounting base and is used to heat the aerosol-forming matrix, the airflow heating device is arranged at the bottom of the mounting base, and the air heated by the airflow heating device is used to heat the aerosol-forming matrix.

[0022] In one of the embodiments, the first airflow channel between the shell and the mounting base is connected to the second airflow channel inside the mounting base through a plurality of airflow holes of the airflow heating device.

[0023] Compared with the prior art, the heating assembly provided by the present invention has the following advantages and beneficial effects:

[0024] 1. In the heating component of the present application, since the heating component has both a heating element and an airflow heating device, and the airflow heating device is fixed on the heating element and spaced apart from the seat body, this arrangement avoids contact between the airflow heating device and other components of the heating component or the heating without combustion device, thereby slowing down the heat dissipation efficiency of the airflow heating device and reducing the power consumption of the heating without combustion device.

[0039] See also Figures 1 to 3 The present application provides a heating assembly 100 . The heating assembly 100 includes a base 110 , a heating element 120 , and an airflow heating device 130 .

[0040] One end of the heating element 120 is fixed in the base 110. The other end of the heating element 120 extends in a direction away from the base 110. The heating element 120 is used to generate heat to heat the aerosol-forming matrix. In actual use, the heating element 120 is inserted into the interior of the aerosol-forming matrix. A part of the heat generated by the heating element 120 after being energized is transferred to the aerosol-forming matrix, and the aerosol-forming matrix is ​​heated. In this embodiment, the heating element 120 is made of metal or ceramic. In another embodiment, the heating element 120 can also be heated by electromagnetic induction to generate heat. In this case, the heating element 120 is made of soft magnetic material.

[0041] The airflow heating device 130 is fixed on the heating element 120 and is spaced apart from the base 110. The airflow heating device 130 is used to generate heat or receive the heat generated by the heating element 120 to heat the air. In actual use, the airflow heating device 130 is located at the bottom of the aerosol forming matrix. After receiving the heat generated by the heating element 120, the temperature of the airflow heating device 130 rises and heats the surrounding air at the same time, thereby preheating the air. When the user inhales the aerosol forming matrix, the hot air generated by the airflow heating device 130 rises, thereby performing secondary heating on the aerosol forming matrix. In this embodiment, the airflow heating device 130 receives the heat generated by the heating element 120 to heat the air. As needed, the airflow heating device 130 can also generate heat by itself to heat the air. At this time, the airflow heating device 130 can generate heat by means of a resistive coating, electromagnetic induction or a resistive heating wire.

[0042] In this embodiment, the airflow heating device 130 is made of a high thermal conductivity material such as aluminum alloy and copper. On the one hand, since the airflow heating device 130 is made of a high thermal conductivity material, the heat generated by the heating element 120 can be quickly transferred to various parts of the airflow heating device 130, thereby effectively heating the surrounding air. On the other hand, metal materials such as aluminum alloy or copper also have good ductility and processability, and can be well processed into the required shape, so that the airflow heating device 130 and the heating element 120 form an effective match.

[0043] In the heating component 100 in the present application, since the heating component 100 has both the heating element 120 and the airflow heating device 130, and the airflow heating device 130 is fixed on the heating element 120 and spaced apart from the base 110, this arrangement avoids contact between the airflow heating device 130 and other components of the heating component 100 or the heating without combustion device, thereby slowing down the heat dissipation efficiency of the airflow heating device 130 and reducing the power consumption of the heating without combustion device.

[0044] In fact, in actual use, the heating assembly 100 of the present application creatively combines the central heating of the heating-without-combustion device and the airflow heating, and effectively avoids the disadvantages of the two heating methods:

[0045] On the one hand, the heating element 120 is only partially inserted into the aerosol-forming substrate, so that the temperature at the center of the aerosol-forming substrate does not rise too quickly and exceed the combustion temperature of the aerosol-forming substrate.

[0046] On the other hand, an airflow heating device 130 is fixed to the heating element 120. Another part of the heat generated by the heating element 120 after being powered on is transferred to the airflow heating device 130, and the surrounding air is heated by the airflow heating device 130. When the user inhales, the hot air generated by the airflow heating device 130 rises, thereby performing secondary heating on the aerosol-forming substrate. Since the airflow heating method heats the aerosol-forming substrate more evenly, it can also effectively prevent the temperature of the aerosol-forming substrate from exceeding its combustion temperature.

[0047] On the other hand, since the airflow heating device 130 is spaced apart from the base 110, it does not contact any part of the heating assembly 100 except the heating element 120, nor does it contact other parts of the heating without burning device. In other words, the heat received by the airflow heating device 130 is basically used to heat the surrounding air. This arrangement can greatly enhance the heat utilization efficiency of the airflow heating device 130, thereby reducing the power consumption of the heating without burning device.

[0048] Please also see Figure 4, the heating element 120 passes through the airflow heating device 130 so that the airflow heating device 130 is fixed on the heating element 120. Specifically, the airflow heating device 130 is a cylindrical structure. A mounting hole 131 is provided at the center of the airflow heating device 130. The heating element 120 passes through the mounting hole 131 so that the airflow heating device 130 is fixed on the heating element 120. In this embodiment, a plurality of airflow holes 132 are provided in the axial direction of the airflow heating device 130. The plurality of airflow holes 132 are arranged around the mounting hole 131 and are evenly distributed along the circumferential direction of the airflow heating device 130. It should be noted that the main function of the airflow heating device 130 is to heat the surrounding air, so that when the user inhales, the air heated by the airflow heating device 130 can perform secondary heating on the aerosol-forming matrix. Then, by providing a plurality of airflow holes 132 in the axial direction of the airflow heating device 130, the contact area between the airflow heating device 130 and the surrounding air can be effectively increased, thereby effectively realizing the heating effect of the airflow heating device 130 on the surrounding air. In addition, the plurality of airflow holes 132 provided in the axial direction of the airflow heating device 130 can also serve as the airflow channel of the heating-not-burning device. In actual use, the outside air enters from the air inlet, passes through the air inlet channel inside the shell, and then enters the aerosol-forming matrix through the plurality of airflow holes 132 of the airflow heating device 130, thereby heating the aerosol-forming matrix. By providing a plurality of airflow holes 132 on the airflow heating device 130 and cooperating with the setting of the air inlet channel, the heat generated by the airflow heating device 130 in all directions can be fully utilized, thereby increasing the heat utilization efficiency of the airflow heating device 130. In this embodiment, the aperture range of the airflow holes 132 is generally set between 0.15mm-0.25mm. When the airflow heating device 130 heats the surrounding air, the above aperture setting can make it easier to form convection of hot air flow at the airflow hole 132, so that the heat can be more easily transferred to the aerosol forming matrix, thereby accelerating the heating speed of the aerosol forming matrix and improving the heating efficiency of the heating component 100.

[0049] In this embodiment, the airflow heating device 130 is spaced apart from the base 110. A first air gap is formed between the airflow heating device 130 and the base 110. As needed, the spacing between the airflow heating device 130 and the base 110 ranges from 2mm to 10mm. By spacing the airflow heating device 130 and the base 110 apart, the heat generated by the airflow heating device 130 can basically be used to heat the surrounding air, so that it is not easy to be transferred to the outside through the base 110, thereby causing unnecessary heat loss. In fact, in addition to the part fixed on the base 110, the heating element 120 can be roughly divided into three parts: a top part, a middle part and a bottom part. The top part of the heating element 120 is inserted into the interior of the aerosol forming matrix for heating the aerosol forming matrix. The middle part of the heating element 120 is provided with the airflow heating device 130, which is used to transfer part of the heat to the airflow heating device 130, so that the airflow heating device 130 is used to heat the surrounding air, and when the user inhales, the heated air is used to reheat the aerosol-forming matrix. The heat emitted by the bottom part of the heating element 120, that is, the part located between the airflow heating device 130 and the seat 110, is not wasted. The heat emitted by the bottom part of the heating element 120 can heat the air between the airflow heating device 130 and the seat 110. When the user inhales, the air between the airflow heating device 130 and the seat 110 can also be used by the airflow heating device 130 to heat the aerosol-forming matrix again.

[0050] In this embodiment, the airflow heating device 130 and the heating element 120 are assembled together by interference fit. In fact, in order to achieve consistency in product assembly, a limiting portion may be further provided on the heating element 120. The airflow heating device 130 is spaced apart from the seat 110 by the limiting portion. At this time, the spacing between the airflow heating device 130 and the seat 110 can be precisely controlled by the limiting portion.

[0051] Please also see Figure 5, another embodiment of the present application provides a method for realizing a limiting portion. In this embodiment, the limiting portion is an annular step 121 provided on the heating element 120. The bottom of the airflow heating device 130 is fixed on the annular step 121. In this embodiment, when the airflow heating device 130 is assembled to the middle of the heating element 120, due to the limiting effect of the annular step 121, when the airflow heating device 130 contacts the annular step 121, the airflow heating device 130 cannot continue to move downward, thereby ensuring the distance between the airflow heating device 130 and the seat body 110, so as to fully realize the spaced arrangement of the airflow heating device 130 and the seat body 110.

[0052] Please also see Figure 6 , yet another embodiment of the present application provides a method for realizing a limiting portion. In this embodiment, the limiting portion is a dot-shaped protrusion 122 provided on the heating element 120. The bottom of the airflow heating device 130 is fixed on the dot-shaped protrusion 122. In this embodiment, when the airflow heating device 130 is assembled to the middle of the heating element 120, due to the limiting effect of the dot-shaped protrusion 122, when the airflow heating device 130 contacts the dot-shaped protrusion 122, the airflow heating device 130 cannot continue to move downward, thereby ensuring the spacing between the airflow heating device 130 and the seat body 110, and also realizing the spaced arrangement of the airflow heating device 130 and the seat body 110.

[0053] Please also see Figures 7 to 9 The present application also provides a heat-not-burn device 200 . The heat-not-burn device 200 includes a housing 210 and a heating assembly 100 disposed in the housing 210 .

[0054] The housing 210 has a mounting seat 220 therein. The mounting seat 220 accommodates and mounts the aerosol-forming substrate 300.

[0055] The heating assembly 100 is a heating assembly 100 as described in any of the above embodiments. The heating assembly 100 is arranged in the housing 210. The heating element 120 partially extends into the interior of the mounting seat 220 and is used to heat the aerosol-forming substrate 300. The airflow heating device 130 is arranged at the bottom of the mounting seat 220. The air heated by the airflow heating device 130 is used to heat the aerosol-forming substrate 300. In this embodiment, the air heated by the airflow heating device 130 flows through the mounting seat 220 and heats the aerosol-forming substrate 300.

[0056] In the heating without burning device 200 of the present application, since the heating element 120 partially extends into the interior of the mounting seat 220 and heats the aerosol-forming matrix 300, and the air heated by the airflow heating device 130 also heats the aerosol-forming matrix 300 at the same time, the above heating method undoubtedly greatly reduces the possibility of the heat generated by the heating element 120 being dissipated to the outside, and increases the energy utilization efficiency of the heating element 120. In addition, similarly, since the heating component 100 has both the heating element 120 and the airflow heating device 130, and the airflow heating device 130 is fixed on the heating element 120 and spaced apart from the seat 110, this arrangement avoids the airflow heating device 130 from contacting the heating component 100 or other components of the heating without burning device 200, thereby slowing down the heat dissipation efficiency of the airflow heating device 130 and reducing the power consumption of the heating without burning device 200.

[0057] In this embodiment, a first air flow channel L1 is formed between the housing 210 and the mounting base 220. External air enters the heating assembly 100 through the first air flow channel L1.

[0058] A second airflow channel L2 is formed inside the mounting base 220. The outside air entering from the first airflow channel L1 is heated by the heating assembly 100, flows out from the second airflow channel L2 and performs secondary heating on the aerosol-forming substrate 300.

[0059] A second air gap is formed between the outer wall surface of the airflow heating device 130 and the shell 210 , and the second air gap is a part of the first airflow channel L2 .

[0060] In fact, the above arrangement of the first airflow channel L1 and the second airflow channel L2 can fully ensure that the heat generated by the heating component 100 can be fully utilized. Specifically, the first airflow channel L1 and the second airflow channel L2 are connected through the multiple airflow holes 132 in the airflow heating device 130. This method can fully ensure that the heated air in the multiple airflow holes 132 can be effectively transferred to the aerosol-forming substrate 300, thereby heating the aerosol-forming substrate 300. On the other hand, since the outer wall surface of the airflow heating device 130 is isolated from the shell 210, a part of the first airflow channel L1 is formed. At this time, the outer wall surface of the airflow heating device 130 can also heat part of the air in the first airflow channel L1, and the heated air passes through the multiple airflow holes 132 in the airflow heating device 130 to reach the aerosol-forming substrate 300, and can also heat the aerosol-forming substrate 300. On the other hand, since the bottom surface of the airflow heating device 130 is isolated from the base 110 and this part is also located between the first airflow channel L1 and the second airflow channel L2, the bottom surface of the airflow heating device 130 can also heat the air between the airflow heating device 130 and the base 110. Further, the area where the heating element 120 is located in this part can also heat the air between the airflow heating device 130 and the base 110. The heated air passes through the multiple airflow holes 132 in the airflow heating device 130 to reach the aerosol-forming substrate 300, and can also achieve the effect of heating the aerosol-forming substrate 300. It can be seen that, whether it is the heating element 120 or the airflow heating device 130, through the arrangement of the first airflow channel L1 and the second airflow channel L2, the heat generated by them is basically not wasted, thereby reducing the power consumption of the heat-not-burning device 200.

[0061] In this embodiment, the first airflow channel L1 between the shell 210 and the mounting seat 220 is connected to the second airflow channel L2 inside the mounting seat 220 through the plurality of airflow holes 130 of the airflow heating device 130. As required, the spacing between the outer wall of the airflow heating device 130 and the shell 210 ranges from 2 mm to 10 mm. The above spacing can effectively ensure that the airflow heating device 130 is spaced apart from the seat 110, and can also effectively heat the air between the outer wall of the airflow heating device 130 and the shell 210.

[0062] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" may include both "above" and "below". The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0063] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.
