The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0046] Please refer to Figure 1-4 as well as Figure 9This application provides an embodiment of an aerosol generating device 100, comprising: a housing 1 having a proximal end 11a and a distal end 11b arranged along the length direction, and defining a receiving space 12; a battery assembly 2 disposed within the housing 1, the receiving space 12 including a first receiving cavity 121 and a second receiving cavity 122, the battery assembly 2 being received in the first receiving cavity 121, the battery assembly 2 being provided with a first electrode 21, a portion of the first electrode 21 being exposed in the second receiving cavity 122; and a charging adapter 3 receivable in the second receiving cavity 122, having a first end 31a and a second end 31b arranged along the length direction, the first end 31a being provided with a power interface 32 for connecting to an external power source, and the second end 31b being provided with a second electrode 33, wherein when the charging adapter 3 is received in the second receiving cavity 122, the second electrode 33 and the first electrode 21 are electrically connected.

[0047] The housing 1 and battery assembly 2 constitute the main body of the aerosol generating device 100, also referred to as the battery rod. The battery assembly 2 is positioned near the distal end 11b. The atomizer can be inserted into the second receiving cavity 122 from the proximal end 11a. The atomizer is connected to the battery assembly 2. The user operates the aerosol generating device 100 according to its defined functions. In one example, the battery assembly 2 operably supplies current to the atomizer, which heats and atomizes the aerosol generating matrix carried inside to produce an aerosol. When the aerosol generating matrix in the atomizer is used up, the aerosol generating device 100 can be used again by removing the atomizer from the second receiving cavity 122 and replacing it with a new atomizer.

[0048] Meanwhile, the aerosol generating device 100 is compatible with the charging adapter 3, meaning the charging adapter 3 can also be installed in the second receiving cavity 122, and the charging adapter 3 is connected to the battery assembly 2. Figure 3 The arrows indicate the insertion directions of the charging adapter 3 and the battery assembly 2. In one example, the charging adapter 3 is connected to an external power source to charge the battery assembly 2.

[0049] The first electrode 21 serves as the electrical contact for the electrical connection between the atomizer and the charging adapter 3. By reusing the first electrode 21, the number of first electrodes 21 is reduced, thereby reducing the cost of the aerosol generating device 100 and improving the aesthetic appearance of the aerosol generating device 100.

[0050] In one example, the housing 1 is constructed in a cylindrical shape. Accordingly, the first receiving cavity 121 and the second receiving cavity 122 are also cylindrical spaces, and for this purpose, the portion of the atomizer and charging adapter 3 received in the second receiving cavity 122 is also constructed in a cylindrical shape. It is understood that the housing 1 can also be constructed in an elliptical, teardrop, square, or other shape depending on the product shape of the aerosol generating device 100.

[0051] In some embodiments, at least a portion of the charging adapter 3 and the atomizer are adapted to the inner surface of the second receiving cavity 122; or, the charging adapter 3 and the atomizer have substantially the same side surface profile. Thus, the atomizer and the charging adapter 3 can be smoothly inserted into the second receiving cavity 122. Furthermore, the second electrode 33 and the first electrode 21 are also adapted, so that when the charging adapter 3 is received in the second receiving cavity 122, the second electrode 33 and the first electrode 21 can just abut against each other, achieving an electrical connection.

[0052] Please refer to Figure 2-11 The battery assembly 2 has two first electrodes 21, namely first electrode 21a and first electrode 21b. The second end 31b of the charging adapter 3 has two second electrodes 33, namely second electrode 33a and second electrode 33b. When the charging adapter 3 is received in the second receiving cavity 122, the second electrode 33a and the first electrode 21a are electrically connected, and the second electrode 33b and the first electrode 21b are electrically connected. In addition, the first electrode 21a is also connected to the positive terminal 221a of the battery cell, and the first electrode 21b is also connected to the negative terminal 221b of the battery cell.

[0053] In some embodiments, the first electrode 21 includes a conductive post and the second electrode 33 includes a conductive tube. When the charging adapter 3 is received in the second receiving cavity 122, the conductive post is at least partially inserted into the conductive tube to establish an electrical connection.

[0054] In other embodiments, the first electrode 21 includes a metal spring electrode needle or a metal spring sheet, and the second electrode 33 includes a metal contact. When the charging adapter 3 is received in the second receiving cavity 122, the metal spring electrode needle or metal spring sheet elastically abuts against the metal contact to establish an electrical connection.

[0055] In some other embodiments, the battery assembly 2 and / or the charging adapter 3 are provided with magnets, and when the charging adapter 3 is received in the second receiving cavity 122, the first electrode 21 and the second electrode 33 are kept in contact under the attraction of the magnets to establish an electrical connection.

[0056] Based on the interaction between magnetic fields, opposite magnetic poles exhibit mutual attraction. When the charging adapter 3 is received in the second receiving cavity 122, the charging adapter 3 and the battery assembly 2 can be better fixed, ensuring the stability of the charging process when the battery assembly 2 is charged using the charging adapter 3.

[0057] It is understood that the first electrode 21 and the second electrode 33 can be made of conductive metal or insulating material, and have a conductive layer plated on their outer surface, which has good anti-oxidation properties and low contact resistance.

[0058] In some embodiments, when the charging adapter 3 is received in the second receiving cavity 122, the first end 31a is located outside the second receiving cavity 122. On the one hand, the first end 31a being located outside the second receiving cavity 122 makes it convenient for the user to hold the charging adapter 3, thereby facilitating the insertion and removal of the charging adapter 3. On the other hand, the first end 31a being located outside the second receiving cavity 122 exposes the power interface 32, facilitating connection to an external power source.

[0059] In some embodiments, the power interface 32 is a USB interface. In an optional embodiment, the power interface 32 is a USB-C female connector, which is connected to an external power source, such as a power bank, charger, socket, or smart terminal, via a USB cable.

[0062] In some embodiments, the battery assembly 2 further includes a seal 25 disposed on the side of the control circuit board 24 away from the battery cell, with the first electrode 21 passing through the seal 25 to be at least partially exposed in the second receiving cavity 122.

The battery cell 22 faces the first surface of the control circuit board 24, and the positive electrode 221a and the negative electrode 221b of the battery cell 22 are electrically connected to the first surface of the control circuit board 24. The first electrode 21a and the first electrode 21b are disposed on the second surface of the control circuit board 24, thereby being electrically connected to the battery cell 22, and the free ends of the first electrode 21a and the first electrode 21b extend into the second receiving cavity 122.

[0067] The cross-sections of the cell support 23, the control circuit board 24, and the seal 25 are all circular, and the diameters of the cell support 23, the control circuit board 24, and the seal 25 are equal.
