Description

Technical Field

[0001] This application relates to the field of heated cigarette technology, and in particular to a heating component and a heated cigarette device. Background Technology

[0002] Heated non-combustible technology using air heating involves heating the intake of cold air with a heating element. The heated air then steams the tobacco products, achieving the goal of heating the tobacco to form an aerosol while preventing the tobacco from burning. This provides a similar satisfaction to cigarettes while reducing the generation of harmful substances during combustion.

[0003] The heating element is used to heat cold air to produce hot air and is the core component of a heated smoke appliance. Heating elements that use the principle of electric heating tubes include heating wires made of metal or non-metal. When the heating wire is energized, it generates heat and transfers the heat to the heat transfer tubes. Cold air is heated inside the heat transfer tubes to form hot air.

[0004] Electric heating element devices have the following disadvantages: First, they have low thermal efficiency, slow heating speed, and high energy consumption. Second, because the heating wire needs to transfer heat, it is generally exposed (i.e., the surface of the heating wire is not covered with insulation), posing a risk of electric leakage. Third, the air heating tube connected to the heating wire needs to be made of insulating material, which affects the air heating efficiency and also affects the heat transfer to the cigarette, adversely affecting the cigarette heating efficiency. Fourth, the heating wire has high thermal resistance, is prone to oxidation and damage, has a short lifespan, and a high failure rate. Fifth, it is difficult to maintain the temperature, making it difficult to achieve high-temperature heating; the heating temperature is generally below 300℃. Utility Model Content

[0006] The technical solution provided by this utility model is as follows:

[0007] A heating assembly includes a housing and an electromagnetic coil.

[0020] Preferably, the acute angle formed by the second ring, the guide element, and the vertical direction is 30-60°.

[0021] Preferably, the second ring and the guide are tilted at the same angle.

[0022] Preferably, the connecting column is provided with 2-6 heating elements, and the number of guide elements provided on the inner wall of the housing is one less than the number of heating elements.

[0023] Preferably, the heating element is made of metal; or,

[0024] Both the heating element and the airflow guiding element are made of metal.

[0025] A heated smoke appliance, comprising the heating component described in any one of the above claims.

[0026] Preferably, the outer casing of the smoking device has an air inlet and a cavity for containing the smoke-generating substance.

[0027] The air inlet is connected to the air intake.

[0028] One end of the receiving cavity is connected to the air outlet, and the other end penetrates through the outer shell of the smoking device.

[0029] This application provides a heating assembly, including a housing and an electromagnetic coil.

The electromagnetic coil is located on the outer periphery of the housing and electrically connected to a power source. A connecting post is fixedly installed inside the housing, and at least two heating elements are mounted on the connecting post.

[0042] As shown in the figure, this embodiment of the present invention provides a heating assembly, including a housing 1 and an electromagnetic coil 2.

[0043] The housing 1 has an air inlet 11 and an air outlet 12 at both ends, and a heating air duct 13 is formed inside.

[0044] The electromagnetic coil 2 is located on the outer periphery of the housing 1 and is electrically connected to the power supply;

[0045] A connecting column 3 is fixedly installed inside the housing 1. At least two heating elements 4 are provided on the connecting column 3. At the same time, at least one air guide 5 is provided on the inner wall of the housing 1. One of the heating elements 4 is located between the air inlet 11 and the air guide 5.

[0046] The heating element 4 and the air guide 5 are alternately arranged along the axial direction of the heating air duct 13;

[0047] Furthermore, along the axial direction of the heating air duct 13, the projection of the outer edge of the heating element 4 onto the plane overlaps at least partially with the projection of the edge of the guide element 5 away from the housing 1 onto the plane.

[0048] This application provides a heating assembly, including a housing 1 and an electromagnetic coil 2. The housing 1 has an air inlet 11 and an air outlet 12 at its two ends, respectively, forming a heating air duct 13 inside. Air enters through the air inlet 11, passes through the heating air duct 13, and flows out through the air outlet 12, being heated in the process. The electromagnetic coil 2 is located on the outer periphery of the housing 1 and electrically connected to a power source. A connecting post 3 is fixedly installed inside the housing 1, and at least two heating elements 4 are mounted on the connecting post 3. The electromagnetic coil 2 on the outer periphery utilizes the principle of electromagnetic induction (a changing magnetic field is generated around a coil carrying a changing current, and a changing current is induced inside the heating element within the changing magnetic field. The induced current flows inside the metal, generating Joule heating) to heat the components located on the housing 1. The heating element 4 inside the housing 1 heats up rapidly on its own; at the same time, at least one guide element 5 is provided on the inner wall of the housing 1, and one of the heating elements is located between the air inlet and the guide element. The heating element 4 and the guide element 5 are alternately arranged along the axial direction of the heating air duct 13 and are both located within the heating air duct 13. Moreover, along the axial direction of the heating air duct 13, the projection of the outer edge of the heating element 4 on the plane overlaps with the projection of the edge of the guide element 5 away from the housing 1 on the plane in at least a partial area. When the air flows in the heating air duct 13, it is first heated by the heating element closest to the air inlet, and then alternately blocked by the heating element 4 and the guide element 5, flowing along a tortuous path. During this process, the heat exchange between the air and the heating element 4 is more complete, and the heating efficiency is higher.

[0049] The heating assembly provided in this application uses electromagnetic induction to generate heat from the heating element, and the arrangement of the heating element 4 and the air guide 5 causes the air to flow in a zigzag pattern, resulting in high heating efficiency.

[0050] In this application, the projection of the outer edge of the heating element 4 onto the plane along the axial direction of the heating air duct 13 overlaps at least partially with the projection of the edge of the guide element 5 away from the housing 1 onto the plane. This means that along the axial direction of the heating air duct 13, the overlapping area contains a portion of the structure of the heating element 4 and a portion of the structure of the guide element 5, which respectively obstruct the flow of air, change the direction of airflow, and cause the airflow to flow in a tortuous manner.

[0051] Preferably, the connecting column 3 is arranged along the central axis of the heating air duct 13;

[0052] The heating element 4 is ring-shaped and is located on the outer periphery of the connecting column 3;

[0053] The guide element 5 is circular at the edge away from the housing 1.

[0054] Preferably, the connecting column 3 is arranged along the central axis of the heating air duct 13 and is located at the center of the heating air duct 13, while the heating element 4 is annular and is arranged on the outer periphery of the connecting column 3, maintaining a uniform distribution on the outer periphery of the connecting column 3; at the same time, the guide element 5 is circular at the edge away from the shell 1 (i.e. the edge close to the heating element 4), which cooperates with the annular heating element 4, so that the overlapping area of ​​the two is also annular. Therefore, no matter where the air enters, it will be blocked by the heating element 4 or the guide element 5, thereby prolonging the heat exchange time with the heating element 4.

[0055] Preferably, the heating element 4 includes a first ring 41 and a second ring 42 connected together, with the first ring 41 located on the inner side and the second ring 42 located on the outer side;

[0056] The first ring 41 is perpendicular to the axis of the heating air duct 13; the second ring 42 is inclined and forms an angle with the first ring 41.

[0057] The flow guide 5 is also set at an angle.

[0058] Further preferred heating element 4 includes a first ring 41 and a second ring 42 connected together. The first ring 41 is located on the inner side and the second ring 42 is located on the outer side. The first ring 41 is perpendicular to the axis of the heating air duct 13. The second ring 42 is inclined and forms an angle with the first ring 41. The guide element 5 is also inclined, making the spatial changes in the heating air duct 13 more complex and the air flow more tortuous.

[0059] Preferably, the inner side of the second ring 42 is close to the air outlet 12 and the outer side is close to the air inlet 11;

[0060] The side of the air guide 5 closest to the inner wall of the housing 1 is close to the air inlet 11, while the side furthest from the housing 1 is close to the air outlet 12.

[0061] Preferably, the acute angle formed by the second ring 42, the guide member 5 and the vertical direction is 30-60°.

[0062] Preferably, the second ring 42 and the guide member 5 are tilted at the same angle.

[0063] The orientation and angle of the second ring 42 can be the same as or different from the orientation and angle of the guide 5, both of which can disturb the airflow.

[0064] Preferably, the two elements are tilted in the same direction, i.e., the inner side of the second ring 42 is closer to the air outlet 12 and the outer side is closer to the air inlet 11, while the side of the guide member 5 closest to the inner wall of the housing 1 is closer to the air inlet 11, and the side furthest from the housing 1 is closer to the air outlet 12. This arrangement allows for a larger overlap area between the second ring 42 and the guide member 5 without affecting airflow, resulting in a longer airflow path. Preferably, the acute angle formed by the second ring 42, the guide member 5, and the vertical direction is 30-60°. More preferably, the second ring 42 and the guide member 5 are tilted at the same angle.

[0065] Preferably, the connecting column 3 is provided with 2-6 heating elements 4, and the number of guide elements 5 provided on the inner wall of the housing 1 is one less than the number of heating elements 4.

[0066] The number of heating elements 4 provided in a heating assembly is preferably 2-6, more preferably 3-5. Correspondingly, the number of guide elements 5 provided on the inner wall of the housing 1 is one less than the number of heating elements 4, so as to realize that the heating elements 4 and the guide elements 5 are alternately arranged in the heating air duct 13.

[0067] Preferably, the heating element 4 is made of metal; or,

[0068] Both the heating element 4 and the flow guide 5 are made of metal.

[0069] Preferably, the heating element 4 is made of metal, or both the heating element 4 and the flow guide 5 are made of metal. Metal materials (such as steel) can generate heat under the action of the electromagnetic coil 2. When both the heating element 4 and the flow guide 5 are made of metal, the flow guide 5 can not only guide the flow, but also generate heat itself, thus playing a role in heat exchange and further improving the heat exchange efficiency.

[0071] This application also provides a heated smoke appliance that uses the heating component described in any of the above claims to heat air.

[0073] The air inlet 61 is connected to the air inlet 11;

[0074] One end of the receiving cavity 62 is connected to the air outlet 12, and the other end passes through the outer shell 6 of the smoking device.

[0075] Preferably, the outer shell 6 of the heated smoking device is provided with an air inlet 61 and a receiving cavity 62 for containing the smoke-generating substance. The air inlet 61 is connected to the air inlet 11, and when smoking, outside air enters the outer shell 6 and flows into the air inlet 11 of the heating component.
