[0032] This application provides an aerosol generating device 100, such as... Figure 1 As shown, the aerosol generating device 100 can be used to atomize an aerosol generating matrix to generate aerosols for consumption by users. This application provides an embodiment of an aerosol generating device 100 with a removable battery, such as... Figures 1-4 As shown, the aerosol generating device 100 includes a housing assembly 1, a battery 2, a base 3, and an atomizer 4. The housing assembly 1 has an internal accommodating cavity 11 for housing the battery 2, the atomizer 4, and other internal components to protect them from external environmental influences. The battery 2 is detachably housed in the accommodating cavity 11 and provides power to the aerosol generating device 100. The base 3 is removably connected to the housing assembly 1 and seals the accommodating cavity 11. At least a portion of the base 3 extends into the accommodating cavity 11 to support the battery 2. When the user removes the battery, the base 3 can be removed to take out the battery 2 separately. As an alternative embodiment, the battery 2 is integrated with components such as a battery holder 15 and a circuit board 22. When the user removes the battery 2, the battery holder 15 and the circuit board 22 are removed together with the battery 2.

[0033] Furthermore, the base 3 includes a first mechanical engagement feature 31, and the housing assembly 1 includes a second mechanical engagement feature 12. The first mechanical engagement feature 31 and the second mechanical engagement feature 12 cooperate with each other to keep the base 3 and the housing assembly 1 connected. This structure provides a reliable connection method, making the connection between the base 3 and the housing assembly 1 tight, while facilitating disassembly using tools.

[0034] Furthermore, at least one gap 13 is defined between the base 3 and the housing assembly 1. The gap 13 provides a disassembly tool to be inserted to drive one of the first mechanical engagement feature 31 and the second mechanical engagement feature 12 to shift or deform relative to the other, thereby detaching the connection between the base 3 and the housing assembly 1. The gap 13 provides operating space for the disassembly tool. When the user wants to remove the battery, he / she needs to insert the tool into the gap 13 to disconnect the connection between the base 3 and the housing assembly 1, reducing the risk of the battery accidentally detaching from the housing.

[0035] In one embodiment of this application, the aerosol generating matrix comprises a liquid of at least one aerosol forming material, such as glycerol. In some alternative examples, the aerosol generating matrix may comprise tobacco extracts or other plant extracts, synthetic alkaloids, or pharmaceutical ingredients. For example, the aerosol forming material may comprise a combination of nicotine salts, glycerol, propylene glycol, and a cooling agent or flavoring agent. It has been found that aerosol forming materials improve the sensory properties of the aerosol generating matrix by facilitating the transfer of compounds (e.g., flavor compounds) from the aerosol generating material to the consumer.

[0036] In one embodiment of this application, such as Figures 1-4 As shown, the first mechanical engagement feature 31 and the second mechanical engagement feature 12 together form a snap-fit ​​connection, which simplifies the connection and disassembly process and improves the stability and reusability of the connection.

[0037] As an example, such as Figures 1-4 As shown, one of the first mechanical engagement feature 31 and the second mechanical engagement feature 12 is a protruding structure 32, and the other is a recessed structure 16 for receiving the protruding structure 32. The two structures achieve a tight fit through complementary shapes, which enhances the strength of the connection and simplifies the assembly process.

[0038] In one embodiment of this application, such as Figures 1-4 As shown, the housing assembly 1 includes a housing 14 and a battery bracket 15. The battery bracket 15 is fixed inside the housing 14 to fix the battery position, prevent the battery from shifting during device use, and protect the battery from impact.

[0039] As an example, such as Figures 1-4 As shown, the recessed structure 16 is provided on the part of the battery bracket 15 near the base 3, which facilitates its cooperation with the protruding structure 32 of the base 3 and improves the stability of the connection between the battery bracket 15 and the base 3.

[0040] As an example, such as Figure 1As shown, a circuit board 22 is installed above the end of the battery 2 away from the base 3. The circuit board 22 integrates an electronic control unit to manage the charging and discharging process of the battery, monitor the operating status of the device, and ensure the safety and functionality of the device.

[0041] In one embodiment of this application, such as Figure 1 As shown, a first contact electrode 21 is provided at the end of the battery 2 away from the base 3, and a second contact electrode 151 is provided on the battery bracket 15. The base 3 supports the battery 2 from the other end so that the first contact electrode 21 and the second contact electrode 151 keep in contact, ensuring an effective connection between the battery and the device circuit, and transmitting electrical energy to power the device.

[0042] As an example, the first contact electrode 21 is a battery cell tab, and the second contact electrode is a conductive spring. The battery cell tab, as an inherent part of the battery 2, can provide a stable electrical connection point, which is convenient for connection with external circuits. The conductive spring is elastic, which can absorb vibration, reduce poor contact caused by equipment vibration, and provide reliable contact pressure to ensure good electrical contact between the battery cell tab and the conductive spring, reduce contact resistance, and improve power transmission efficiency.

[0043] As another example, the first contact electrode 21 is a battery cell plug, and the second contact electrode is a socket. The battery cell plug has a specific shape and size that can precisely match the socket. The socket is designed with an internal structure corresponding to the battery cell plug to ensure stable fixation after the plug is inserted. This design provides a plug-and-play electrical connection method, allowing users to quickly insert or remove the battery cell plug from the socket, facilitating battery replacement. In addition, the matching design of the battery cell plug and socket provides a low-resistance contact surface, reducing energy loss and improving the efficiency of battery 2.

[0044] In one embodiment of this application, such as Figure 1 , Figure 3 As shown, the base 3 includes an abutment portion 33 for supporting the battery 2, which can prevent the battery from being damaged by external forces inside the device.

[0045] In one embodiment of this application, such as Figure 1 As shown, a first gap 131 and a second gap 132 are defined between the housing assembly 1 and the base 3, spaced apart along the width direction of the housing assembly 1. The multiple gaps provide the user with multiple disassembly points, increasing the operational flexibility of the disassembly tool, and can also serve as heat dissipation channels.

[0046] As an example, such as Figure 3 As shown, the protruding structure 32 includes a first guide ramp 321 facing the gap 13 for guiding the disassembly tool to operate, so that the user can quickly and accurately disassemble the base.

[0047] As an example, such as Figure 1 , Figure 3 As shown, the protruding structure 32 includes a second guide slope 322 that is opposite to the first guide slope 321. The second guide slope 322 can be received at least partially by the recessed structure 16, providing stable fixation and anti-detachment when the base 3 and the housing assembly 1 are not disassembled, while maintaining the operability of the connecting parts.

[0048] As an example, such as Figure 1 , Figure 3 , Figure 4 As shown, the base 3 is provided with an elastic arm 34 that can be elastically deformed. The protruding structure 32 is provided on the elastic arm 34. The elastic arm 34 provides elastic pressure to ensure a tight fit between the protruding structure 32 and the recessed structure 16, and at the same time, it generates the necessary deformation to release the connection during disassembly.

[0049] 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.
