Description

Technical Field

[0001] This invention relates to the field of aerosol generation equipment technology, and in particular to a heating component and its aerosol generating device. Background Technology

[0002] "Heated-non-combustible" aerosol forming devices are atomization devices that atomize aerosol-generating substrate (such as treated plant leaf products) by heating it without causing the substrate to burn. These devices heat the substrate to a temperature sufficient to produce aerosols but not hot enough to burn, thus generating the desired aerosol for the user.

[0003] In existing "heat-not-combustible" aerosol forming devices, the electromagnetic coil is placed around the heating hardware. The coil occupies a large space, making it difficult to modularize and miniaturize the heating components. Summary of the Invention

[0004] The purpose of this invention is to provide a heating component and its aerosol generating device, which aims to solve the technical problem that existing heating components are difficult to modularize and miniaturize.

[0005] To address the aforementioned problems, according to one aspect of this application, an embodiment of the present invention provides a heating component, which includes a mounting base for inserting an aerosol matrix. The mounting base includes a tubular heating element, the aerosol matrix is ​​inserted into the tubular heating element, and an electromagnetic element is disposed within the tubular heating element to generate eddy current induction to heat the aerosol matrix.

[0006] In some embodiments, the mounting base also includes a base disposed at one end of the tubular heating element along its axial direction, and the electromagnetic element is fixed on the base.

[0007] In some embodiments, the base has a tubular column extending axially into the interior of the tubular heating element, and the electromagnetic element is fixedly mounted on the tubular column.

[0008] In some implementations, both the base and the tubular column are made of high-temperature resistant insulating material.

[0009] In some implementations, the end of the tubular column away from the base is tapered.

[0010] In some embodiments, the electromagnetic element is a double-helix coil extending axially within the tubular heating element.

[0011] In some embodiments, the double helix coil includes a first helix coil and a second helix coil. One end of the first helix coil extending into the tubular heating element is connected to one end of the second helix coil extending into the tubular heating element. The ends of the first helix coil extending out of the tubular heating element and the ends of the second helix coil extending out of the tubular heating element are respectively connected to the two poles of the battery cell.

[0012] In some embodiments, both the first spiral coil and the second spiral coil are conductive spiral coils formed by printing conductive paste onto the outer and / or inner wall of the tubular column.

[0013] In some embodiments, the heating assembly further includes a control board, and the end of the first spiral coil extending outside the tubular heating element, the end of the second spiral coil extending outside the tubular heating element, and the battery cell are all connected to the control board.

[0014] According to another aspect of this application, embodiments of the present invention also provide an aerosol generating device, which includes the heating component described above.

[0015] Compared with the prior art, the heating component of the present invention has at least the following beneficial effects:

The mounting base includes a tubular heating element 21. The aerosol matrix 1 is inserted into the tubular heating element 21. An electromagnetic element 22 is disposed inside the tubular heating element 21 to generate eddy current induction to heat the aerosol matrix 1.

[0031] In this embodiment, the heating component includes a mounting base for inserting the aerosol matrix 1. The mounting base includes a tubular heating element 21. The aerosol matrix 1 is inserted into the tubular heating element 21. An electromagnetic element 22 is disposed inside the tubular heating element 21 to generate eddy current induction to heat the aerosol matrix 1. When the electromagnetic element 22 is energized, it can provide a magnetic field. The tubular heating element 21 is used to sense the magnetic field and generate heat to bake and heat the aerosol matrix 1 and generate aerosol for the user to inhale. It can be seen that the heating component of the present invention has a high degree of modularity, saves space, is conducive to miniaturization design, and optimizes the layout of the product structure.

[0032] In some embodiments, the mounting base also includes a base 23, which is disposed at one end of the tubular heating element 21 along its axial direction, and the electromagnetic element 22 is fixed on the base 23.

[0033] In this embodiment, the mounting base also includes a base 23, which is set at one end of the tubular heating element 21 along the axial direction, and the electromagnetic element 22 is fixed on the base 23. The tubular heating element 21 and the electromagnetic element 22 are integrated into one unit through the base 23, which improves the modularity of the heating component, saves space, facilitates miniaturization design, and optimizes the layout of the product structure.

[0034] In some embodiments, the base 23 has a tubular column 231 extending axially into the interior of the tubular heating element 21, and the electromagnetic element 22 is fixedly disposed on the tubular column 231.

[0035] In this embodiment, by axially providing a tubular column 231 extending into the tubular heating element 21 on the base 23, the electromagnetic element 22 is fixedly installed on the tubular column 231, so that the electromagnetic element 22 is installed firmly and reliably, preventing damage and deformation of the electromagnetic element 22 when the aerosol matrix 1 is inserted into the tubular heating element 21. The electromagnetic element 22 can be provided inside the tubular column 231, or it can be attached to the inner and outer walls of the tubular column 231.

[0036] In some embodiments, both the base 23 and the tubular column 231 are made of high-temperature resistant insulating material.

[0037] In this embodiment, both the base 23 and the tubular column 231 are made of high-temperature resistant insulating material, such as ceramic, quartz or other high-temperature resistant insulating materials, to prevent the base 23 and the tubular column 231 from deforming when the tubular heating element 21 heats the aerosol matrix 1.

[0038] In some embodiments, the end of the tubular column 231 away from the base 23 is tapered.

[0039] In this embodiment, the end of the tubular column 231 away from the base 23 is tapered to facilitate the insertion of the aerosol matrix 1.

[0040] In some embodiments, the electromagnetic element 22 is a double-helix coil extending axially within the tubular heating element 21.

[0041] In this embodiment, the electromagnetic component 22 is a double helical coil extending axially in the tubular heating component 21. After the double helical coil is energized, it generates a magnetic field, which causes the tubular heating component 21 to sense the magnetic field and generate heat, thereby baking and heating the aerosol matrix 1 and generating aerosol for the user to inhale.

[0042] In some embodiments, the double helix coil includes a first helix coil 221 and a second helix coil 222. One end of the first helix coil 221 extending into the tubular heating element 21 is connected to one end of the second helix coil 222 extending into the tubular heating element 21. The ends of the first helix coil 221 extending out of the tubular heating element 21 and the ends of the second helix coil 222 extending out of the tubular heating element 21 are respectively connected to the two poles of the battery cell 3.

[0043] In this embodiment, the double helix coil may include a first helix coil 221 and a second helix coil 222. One end of the first helix coil 221 extending into the tubular heating element 21 is connected to one end of the second helix coil 222 extending into the tubular heating element 21. One end of the first helix coil 221 extending out of the tubular heating element 21 and one end of the second helix coil 222 extending out of the tubular heating element 21 are respectively connected to the two poles of the battery cell 3 to form a current loop and generate a magnetic field. This causes the tubular heating element 21 to sense the magnetic field and generate heat, thereby baking and heating the aerosol matrix 1 and generating aerosol for the user to inhale.

[0044] The first helical coil 221 and the second helical coil 222 can be made by winding wire.

[0045] In some embodiments, the first spiral coil 221 and the second spiral coil 222 are both conductive spiral coils formed by printing conductive paste onto the outer and / or inner wall of the tubular column 231.

[0046] In this embodiment, both the first spiral coil 221 and the second spiral coil 222 are conductive spiral coils formed by printing conductive paste onto the outer wall and / or inner wall of the tubular column 231. Specifically, the first spiral coil 221 and the second spiral coil 222 can be simultaneously printed onto the outer wall or inner wall of the tubular column 231 to form conductive spiral coils. Alternatively, the first spiral coil 221 can be printed onto the outer wall of the tubular column 231 while the second spiral coil 222 is printed onto the inner wall of the tubular column 231, or the first spiral coil 221 can be printed onto the inner wall of the tubular column 231 while the second spiral coil 222 is printed onto both the inner and outer walls of the tubular column 231 to form conductive spiral coils. This eliminates the need for winding with wires, further improves the modularity of the heating component, saves space, facilitates miniaturization design, and optimizes the layout of the product structure.

[0047] In some embodiments, the heating assembly further includes a control board 4, with one end of the first spiral coil 221 extending outside the tubular heating element 21, one end of the second spiral coil 222 extending outside the tubular heating element 21, and the battery cell 3 all connected to the control board 4.

[0048] In this embodiment, the heating component also includes a control board 4. By connecting the end of the first spiral coil 221 extending outside the tubular heating element 21, the end of the second spiral coil 222 extending outside the tubular heating element 21, and the battery cell 3 to the control board 4, the working state of the heating component can be controlled by the control board 4.

[0049] In some embodiments, the heating element further includes a temperature detection line 5, the two ends of which are connected to the tubular heating element 21 and the control board 4, respectively.

[0050] In this embodiment, the heating component also includes a temperature detection line 5, which is connected to the tubular heating element 21 and the control board 4 at both ends to monitor and adjust the temperature of the heating component.
