[0002] As the harm of traditional cigarettes is gradually recognized by the public, electronic cigarettes have been increasingly accepted by smoking consumer groups and are gradually expanding their market share. The essence of electronic cigarettes is an aerosol generating device, which is connected to the atomizer through the host. The battery in the host provides electricity to heat the heating element of the atomizer core in the atomizer, atomizing the oil in the oil tank, thereby generating aerosol for users to inhale.

[0003] For ease of use, the batteries in the host are mostly rechargeable lithium batteries. However, since the atomizer in the aerosol generating device often contains conductive substances such as water vapor and oil mist, leakage or short circuit problems are likely to occur when the aerosol generating device is charged, which will not only affect the life of the battery and the circuit board but also easily cause harm to the user. The existing aerosol generating device does not have a grounding structure to protect the battery, and it is also difficult to arrange it in the limited space of the host, making it difficult to achieve lightness and compactness.

Therefore, the specific implementation methods of other forms of connection methods will not be repeated here.

[0046] This embodiment also discloses an aerosol generating device, which includes the main body structure as described above.

[0047] Embodiment 2:

[0048] like Figure 8As shown, the main difference between the host structure in this embodiment and the host structure in the first embodiment is that the lower bracket screw hole 57 is opened at the top of the battery cover 4, and the lower bracket nail holes 58 are opened on the electrode lower bracket 52 and penetrate the upper and lower ends of the electrode lower bracket 52. The lower bracket screw 59 can pass through the lower bracket nail hole 58 from the top of the electrode lower bracket 52 and screw into the lower bracket screw hole 57 located on the battery cover 4 to fix the electrode lower bracket 52 on the battery cover 4; the electrode spring pin 51 is installed on the electrode lower bracket 52 through the spring pin installation hole 510 opened on the electrode lower bracket 52; the bottom end of the electrode spring pin 51 passes through the spring pin through hole 41 to contact and electrically connect with the battery copper electrode 5; when the battery cover 4 is installed at the battery cover opening 12, the top end of the electrode spring pin 51 can directly contact and electrically connect with the other end of the ground wire 6.
