[0031] The following reference Figures 1-3 A detailed description of the aerosol generating apparatus 100 according to embodiments of this application is provided. It is to be understood that the following description is merely illustrative and not intended to limit the scope of this application.
[0032] It should be noted that the aerosol generating device 100 can be used to heat the aerosol generating article. After heating, the aerosol generating matrix in the aerosol generating article can generate aerosols for inhalation by a user. The aerosol generating matrix can include a liquid of at least one aerosol forming material, such as glycerol. In some alternative examples, the aerosol generating matrix can include tobacco extract, areca nut extract, or other plant extracts, and may also include synthetic alkaloids or pharmaceutical ingredients. For example, the aerosol forming material may include a combination of nicotine salts, glycerol, propylene glycol, and cooling or flavoring agents. It has been found that aerosol forming materials improve the sensory properties of the aerosol generating matrix by helping to transfer compounds (e.g., flavor compounds) from the aerosol generating material to the consumer.
[0033] like Figure 1 As shown, the aerosol generating apparatus 100 according to an embodiment of this application can be used to atomize an aerosol generating matrix to generate aerosols for consumption by users.
[0034] like Figures 1-3 As shown, the aerosol generating device 100 may include a housing assembly 1, a battery cell 2, a main circuit board 3, a transfer circuit board 4, a charging module 5, and a heating needle 6.
[0035] Specifically, the housing assembly 1 has an internal accommodating cavity 11, within which the battery cell 2 is housed. It should be noted that the accommodating cavity 11 can also house the battery cell 2 and other internal components, protecting them from external environmental influences. Furthermore, the accommodating cavity 11 also serves to limit the movement of components such as the battery cell 2; the sidewalls of the accommodating cavity 11 restrict the movement of these components, preventing them from moving within the housing assembly.
[0036] like Figures 1-3 As shown, the battery cell 2 can provide electrical energy to the aerosol generating device 100. One end of the accommodating cavity 11 has an opening 12, through which components such as the battery cell 2 can be installed into the housing assembly 1. Furthermore, the charging module 5 can be disposed in the opening 12, that is, the opening 12 accommodates the charging module 5. On the one hand, the peripheral wall of the opening 12 has a limiting effect on the charging module 5; on the other hand, it also facilitates the electrical connection between the charging module 5 and the battery cell 2 to realize the charging function.
[0037] like Figure 1 As shown, a main circuit board 3 is disposed at the other end of the receiving cavity 11. In other words, the opening 12 is spaced apart from the main circuit board 3, and the main circuit board 3 is disposed opposite to the opening 12. In some examples, the main circuit board 3 may be disposed inside the receiving cavity 11 and located near the other end of the receiving cavity 11; in other examples, the main circuit board 3 may be disposed outside the receiving cavity 11 and located near the other end of the receiving cavity 11.
[0038] It should be noted that the main circuit board 3 rectifies and reduces the voltage of the external current and centrally controls and manages the charging and aerosol generation processes. The main circuit board 3 is electrically connected to one end of the battery cell 2, and the other end of the battery cell 2 is located at the open end 12. For example... Figures 1-3 As shown, the other end of the battery cell 2 is located at the opening 12, and the other end of the battery cell 2 occupies a part of the opening 12. The other part of the opening 12 is used to accommodate the charging module 5.
[0039] like Figure 1 , Figure 3 As shown, the main circuit board 3 is also connected to one end of the adapter circuit board 4. The charging module 5 is positioned at the open opening 12 to seal it, preventing foreign objects from entering, while simultaneously providing the charging function. Figure 1 As shown, the charging module 5 is connected to the housing assembly 1 to fix the charging module 5 and the housing assembly 1 relatively. Furthermore, the charging module 5 is also electrically connected to the other end of the battery cell 2 and the other end of the adapter circuit board 4. It should be noted that during the charging process of the battery cell 2 using the charging module 5, the current flows through the charging module 5 to the adapter circuit board 4, and then to the main circuit board 3. The main circuit board 3 performs voltage reduction and rectification on the current before it flows back into the battery cell 2 from one end, thus achieving the charging of the battery cell 2.
[0040] It is understood that this application adopts an indirect power supply mechanism, that is, the external circuit does not directly supply power to the battery cell 2. Although the external circuit is directly connected to the other end of the battery cell 2, the current does not flow directly into the battery cell 2. The current is guided first through the adapter circuit board 4, and then to the main circuit board 3 for step-down and rectification processing, and finally flows into the battery cell 2 from one end. This design ensures that the current undergoes necessary processing before entering the battery cell 2 to meet the charging needs and safety requirements of the battery cell, and achieves accurate, safe and efficient power supply to the battery cell 2.
[0041] Furthermore, such as Figures 1-3 As shown, one end of the adapter circuit board 4 is a 6-pin connector 41 that connects to the main circuit board 3, and the other end is a 4-pin connector 42 that connects to an external power supply. In this way, the adapter circuit board 4 can be used to convert the connector type.
[0042] Furthermore, such as Figure 2 As shown, one end of the battery cell 2 is in compression contact with the main circuit board 3 through a retractable elastic connector 51, which adapts to the slight displacement between the battery cell 2 and the main circuit board 3, ensuring a continuous and stable electrical connection and improving the reliability and stability of the connection.
[0043] In some examples, such as Figure 2As shown, the other end of the battery cell 2 and the other end of the adapter circuit board 4 are also in compression contact through the retractable elastic connector 51, which improves the reliability and stability of the connection, can adapt to the displacement between different components, and ensures the stable transmission of electrical energy.
[0044] In one embodiment of this application, such as Figures 1-3 As shown, the adapter circuit board 4 is a flexible printed circuit board (FPC). In this way, the flexible printed circuit board (FPC) can adjust its deformation and bending state based on the shape inside the accommodating cavity 11, which can improve space utilization, adapt to the layout of components with different shapes, and enhance the adaptability of the device.
[0045] Furthermore, such as Figures 1-3 As shown, the flexible printed circuit board (FPC) is attached to the outer peripheral wall of the battery cell 2. This reduces the space occupied by the FPC, thereby optimizing the internal spatial layout of the accommodating cavity 11, reducing internal space occupation, and providing a stable electrical connection.
[0046] As an example, such as Figure 1 As shown, the outer peripheral wall of the charging module 5 fits against the inner peripheral wall of the opening 12, ensuring the sealing between the charging module 5 and the housing assembly 1, preventing dust and moisture from entering, and improving the protective performance of the device.
[0047] Furthermore, such as Figure 1 As shown, the outer peripheral wall of the charging module 5 is engaged with the inner peripheral wall of the opening 12, which improves the stability and firmness of the connection and prevents the charging module 5 from loosening or falling off during use.
[0048] As an example, such as Figure 1 As shown, the charging module 5 is detachably connected to the housing assembly 1. For example, the charging module 5 can be detachably connected to the structure at the opening 12. This facilitates the replacement and maintenance of the charging module 5, improving the ease of maintenance and service life of the device. Furthermore, when it is necessary to replace the battery cell 2, the charging module 5 can be removed from the opening 12 to take out the battery cell 2, thereby facilitating the replacement of the battery cell 2.
[0049] In one embodiment of this application, a charging chip is provided on the main circuit board 3. The charging chip is used to control the charging module 5 to charge the battery cell 2 through the adapter circuit board 4, so as to ensure the stability and controllability of the charging process, prevent overcharging or over-discharging, and protect the battery cell 2 and the device.
[0050] It should be noted that the preferred embodiments of this application are given in the specification and accompanying drawings, but are not limited to the embodiments described in this specification. Furthermore, those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
