Description

Technical Field

[0001] The utility model relates to the technical field of aerosol generating devices, and more particularly to an aerosol generating device based on a ceramic matrix. Background Art

[0002] The low-temperature non-combustible cigarette, also known as the low-temperature cigarette, uses an aerosol generating device. When in use, it is paired with a heating device and an aerosol generating matrix. The treated aerosol generating matrix is heated to a certain temperature by a special heating device for the user to inhale. Since the heating temperature of the low-temperature cigarette is relatively low, it effectively avoids the generation of harmful substances by combustion, is more environmentally friendly, and greatly reduces the harm to the human body.

[0003] Currently, the heating devices used in aerosol generating devices are usually cylindrical, and a heating circuit is arranged inside the cylindrical wall. The aerosol generating matrix can be placed inside the cylinder for use. However, in existing aerosol generating devices, the aerosol generating matrix is usually in direct contact with the side and bottom of the heating element, resulting in too small remaining space inside the heating element, making it difficult to inhale. Moreover, the direct contact will over-bake the aerosol generating matrix, causing the aerosol generating matrix to burn and releasing harmful substances.

[0004] Therefore, there is a need to provide an aerosol generating device based on a ceramic matrix to solve the above problems. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an aerosol generating device based on a ceramic matrix to solve the technical problems mentioned in the background art.

[0008] A heating component, the heating component includes a circular tubular first ceramic body and a cylindrical second ceramic body. A first conductive heating sheet is embedded in the first ceramic body. The second ceramic body is fixedly connected to the inner wall of the first ceramic body, and a second conductive heating sheet is embedded in the second ceramic body. Wherein, the first ceramic body and the second ceramic body form a receiving cavity with one end open to receive the aerosol generating matrix;

[0009] A cylindrical first gasket is arranged in the middle of the top end of the second ceramic body. Four second gaskets are evenly arranged on the periphery of the first gasket. Wherein, the second gasket is a cuboid with a square cross-section, and one side of the second gasket is connected to the inner wall of the first ceramic body.

[0010] Further, the inner wall of the first ceramic body is coated with an infrared coating.

The first electrode lead is electrically connected to the first conductive heating sheet and the second conductive heating sheet, the second electrode lead is electrically connected to the first conductive heating sheet, and the third electrode lead is electrically connected to the second conductive heating sheet.

[0013] Furthermore, four barrier cushion strips are arranged on the inner wall of the first ceramic body, and the barrier cushion strips are arranged corresponding to the second gasket.

[0014] Furthermore, the height of the first gasket is equal to the height of the second gasket.

[0015] Furthermore, the area of the top end of the first gasket is larger than the area of the top end of the second gasket.

[0016] Beneficial effects:

[0017] The present utility model provides an aerosol generating device based on a ceramic matrix. By arranging a first gasket and a second gasket at the top end of the second ceramic body in the heating assembly, when the aerosol generating matrix is placed in the accommodating chamber through the open end of the first ceramic body, the remaining gap space in the accommodating chamber is effectively increased, so that the air flow can enter the accommodating chamber from the open end of the first ceramic body and be heated along the gap, and then enter the inside of the aerosol generating matrix to form aerosol, effectively improving the user experience.

[0028] Referring to Figure 1 、 Figures 3 to 4 , the present utility model provides an aerosol generating device based on a ceramic matrix, comprising: a heating assembly 1, wherein the heating assembly 1 includes a circular tubular first ceramic body 101 and a cylindrical second ceramic body 103. A first conductive heating sheet 102 is embedded in the first ceramic body 101. The second ceramic body 103 is fixedly connected to the inner wall of the first ceramic body 101, and a second conductive heating sheet 104 is embedded in the second ceramic body 103. Wherein, the first ceramic body 101 and the second ceramic body 103 form a receiving chamber 105 with an opening at one end to receive an aerosol generating matrix; a cylindrical first gasket 2 is provided in the middle of the top end of the second ceramic body 103, and four second gaskets 3 are evenly arranged on the circumferential side of the first gasket 2. Wherein, the second gasket 3 is a cuboid with a square cross-section, and one side of the second gasket 3 is connected to the inner wall of the first ceramic body 101.

[0029] In the above embodiment, the structure of the first ceramic body 101 sandwiching the first conductive heating sheet 102 and the second ceramic body 103 sandwiching the second conductive heating sheet 104 constitutes the core working components for heating. The materials of the first gasket 2 and the second gasket 3 are high-temperature resistant materials, which may include but are not limited to high-temperature resistant ceramic materials, high-temperature resistant metals or alloys, etc., to ensure that the gaskets will not deform or be damaged in a high-temperature working environment. To further optimize the performance of the heating assembly 1, the first conductive heating sheet 102 and the second conductive heating sheet 104 can be made of materials with high thermal conductivity, such as copper, copper alloy or conductive paste with resistance, which can ensure that the heating sheets can quickly and evenly transfer heat to the receiving chamber 105 during operation, thereby improving the overall thermal efficiency.

[0030] The ceramic materials used for the first ceramic body 101 and the second ceramic body 103 are both alumina ceramics, which have good heat resistance and insulation properties, and can withstand a high-temperature working environment for a long time without deformation or damage. In addition, alumina ceramics also have high mechanical strength, which can effectively protect the internal heating elements and avoid damage caused by external forces.

[0031] By arranging a first gasket 2 and a second gasket 3 at the top of the second ceramic body 103 in the heating component 1, when the aerosol generating matrix is placed in the accommodation chamber 105 through the open end of the first ceramic body 101, the remaining clearance space in the accommodation chamber 105 is effectively increased, enabling the airflow to enter the accommodation chamber 105 from the open end of the first ceramic body 101 and be heated along the clearance, then enter the interior of the aerosol generating matrix to form aerosol, effectively improving the user experience. At the same time, the first gasket 2 and the second gasket 3 can further prevent the aerosol generating matrix from directly contacting the second ceramic body 103, avoiding the problem of charring caused by a relatively high heating temperature, and greatly reducing the health hazards to the user.

[0032] In one embodiment, an infrared coating is applied to the inner wall of the first ceramic body 101.

[0033] In the above embodiment, the infrared coating can absorb part of the heat and convert it into infrared radiation, thereby improving the heat conduction efficiency in the accommodation chamber 105. The infrared radiation can heat the aerosol generating matrix more evenly, enabling the aerosol generating matrix to be heated evenly at a relatively low temperature.

[0034] In one embodiment, a first electrode lead 4 and a second electrode lead 5 are fixedly arranged at the connection between the first ceramic body 101 and the second ceramic body 103, and both the first electrode lead 4 and the second electrode lead 5 are electrically connected to the first conductive heating sheet 102 and the second conductive heating sheet 104.

[0035] In the above embodiment, the first electrode lead 4 and the second electrode lead 5 are respectively welded and fixedly connected at the connection between the first ceramic body 101 and the second ceramic body 103. One of the first electrode lead 4 and the second electrode lead 5 is used as the negative electrode lead, and the other is used as the positive electrode lead. Both the first electrode lead 4 and the second electrode lead 5 are electrically connected to the first conductive heating sheet 102 and the second conductive heating sheet 104.

[0036] Reference Figure 2 In another embodiment, a first electrode lead, a second electrode lead, and a third electrode lead are fixedly arranged at the connection between the first ceramic body and the second ceramic body. The first electrode lead is electrically connected to the first conductive heating sheet and the second conductive heating sheet, the second electrode lead is electrically connected to the first conductive heating sheet, and the third electrode lead is electrically connected to the second conductive heating sheet.

[0037] In the above embodiments, further, a third electrode lead 7 may be provided, such that the first electrode lead 4 serves as the negative electrode main lead, the second electrode lead 5 serves as the positive electrode lead of the first conductive heating sheet 102, and the third electrode lead 7 serves as the positive electrode lead of the second conductive heating sheet 104.

[0038] Referring Figure 3 and Figure 4 , in one embodiment, four barrier pads 6 are provided on the inner wall of the first ceramic body 101, and the barrier pads 6 are provided corresponding to the second gasket 3.

[0039] In the above embodiments, the provision of the barrier pads 6 helps to further optimize the heating effect of the aerosol generating matrix in the accommodation chamber 105. The barrier pads 6 can fix the aerosol generating matrix in place, preventing its displacement during suction, thereby ensuring uniform heating. At the same time, the barrier pads 6 can also prevent direct contact between the aerosol generating matrix and the heating assembly 1, effectively preventing the problem of scorching caused by a relatively high heating temperature, and can greatly reduce the health hazards to users.
