The aerosol generating device has two air inlet channels, one of which is arranged in the atomizing chamber, and the other is arranged outside the atomizing chamber. The air inlet channel arranged in the atomizing chamber is an open structure and is not easy to be blocked by oil; even if the air inlet channel outside the atomizing chamber is blocked by oil, the air inlet channel in the atomizing chamber can still be inlet, which does not affect the user's smoking experience.

[0037] Please refer to Figures 1 to 5 The aerosol generating device of this embodiment mainly includes a shell 1, a socket 2, a mounting seat 3 and a heating element 4.

[0039] One end of the shell 1 is provided with an opening, and the mounting seat 3 is installed in the accommodating cavity of the shell 1. One end of the mounting seat 3 is exposed from the opening of the shell 1.

[0041] The end of the atomization cavity 21 away from the opening is the bottom of the atomization cavity 21, and the bottom of the atomization cavity 21 is used to support and position the inserted atomization matrix 5.

[0042] An installation hole 22 is provided at the bottom of the atomization cavity 21. The heating element 4 can be a needle-shaped resistance heating structure. One end of the heating element 4 passes through the installation hole 22 and is inserted into the atomization cavity 21, and the other end of the heating element 4 is located outside the atomization cavity 21.

[0043] In other embodiments, the heating element 4 can also be entirely located in the atomization cavity 21, and the installation hole 22 at the bottom of the atomization cavity 21 is used to pass and connect the cable of the heating element 4.

[0044] In this embodiment, the inner diameter of the installation hole 22 is the same as the outer diameter of the heating element 4, and the installation hole 22 and the heating element 4 can be hermetically connected, so that the e-liquid generated by the atomization matrix 5 will not enter the accommodation cavity of the outer shell 1 from the installation hole 22, and the influence of the e-liquid on other components in the outer shell 1 can be avoided.

[0045] In other embodiments, the inner diameter of the installation hole 22 can also be larger than the outer diameter of the heating element 4, and a sealing structure is provided outside the installation hole 22.

The circumferential side surface of the atomization matrix 5 and the first air inlet groove 231 enclose an air inlet channel. The end of the atomization section of the atomization matrix 5 is an air-permeable surface. The end air-permeable surface of the atomization matrix 5 communicates with the second air inlet groove 232, so that external air can enter the second air inlet groove 232 along the first air inlet groove 231, and then enter the atomization matrix 5 from the end air-permeable surface of the atomization section of the atomization matrix 5. In other words, in the state where the atomization matrix 5 is not inserted, the first air inlet groove 231 and the second air inlet groove 232 communicate with the atomization chamber 21, which belongs to an open structure; in the state where the atomization matrix 5 is inserted, under the combination of the atomization matrix 5, the first air inlet groove 231 and the second air inlet groove 232 are enclosed to form an air inlet channel, and external air can be introduced to the end of the inserted end of the atomization matrix 5.

The curved grooves can increase the path length of the first air inlet groove 231, so that after the atomization matrix 5 is heated, the diffused heat can be fully absorbed by the entering air and then introduced into the atomization matrix 5, which can improve the heat recovery rate and thus improve the heating efficiency.

[0049] In this embodiment, the second air inlet groove 232 may include one or more concentric annular grooves, and the annular grooves surround the installation hole 22. When the second air inlet groove 232 includes a plurality of annular grooves, the second air inlet groove 232 further includes connecting grooves connecting the plurality of annular grooves to make the plurality of annular grooves communicate with each other.
