[0029] The sealing structure 10 provided in the atomization device for heating the aerosol generating substrate to form an aerosol, and the atomization device comprises a control board 21.

[0030] Referring to Figures 3 to 7 As shown in the figure, the sealing structure 10 is provided with an elastic protrusion 11, the center of the elastic protrusion 11 is provided with a mounting hole 12, and the mounting hole 21 is provided with an air flow sensor 22 on the control board 21; the elastic protrusion 11 abuts against the control board 21 and can at least partially elastically deform to seal the air flow sensor 22 in the mounting hole 11.

[0031] The control board 21 can control the operation of the atomization device, and the control board 21 is, for example, a printed circuit board assembly (PCBA). The specific type of the control board 21 is not limited in the present application, and can be specifically set according to user needs.

[0032] In the atomization device, the air flow sensor 22 is mainly used for air flow detection and use state recognition. When the user uses the atomization device, the air flow sensor 22 can accurately detect the change of the air flow, and convert the change into an electrical signal to be transmitted to the control board 21, so that the control board 21 controls the atomization device to perform corresponding work, such as starting to heat the aerosol generating substrate to form an aerosol. It can be understood that the air flow sensor 22 is not limited in the present application, for example, the air flow sensor 22 is a silicon microphone, which has high precision and response speed, so that the atomization device can provide a smoother and more natural use experience. At the same time, the silicon microphone also has the advantages of small size, high stability, good oil-proof performance, etc.

[0033] Further, the elastic protrusion 11 of the present application protrudes away from the sealing structure 10, and the end of the elastic protrusion 11 away from the sealing structure 10 is used to abut against the control board 21.

[0034] The sealing structure 10 of the embodiment of the present application, the elastic protrusion 11 is used to abut against the control plate 21 to be elastically deformed and to keep abutting against the control plate 21 by restoring at least part of the elastic deformation. That is, the elastic protrusion 11 can keep abutting against the control plate 21 at all times, thereby ensuring that the airflow sensor 22 is sealedly surrounded in the mounting hole 11 by abutting against the control plate 21, ensuring the sealing of the airflow sensor 22, improving the firmness of the airflow sensor 22, making the airflow sensor 22 more sensitive and improving the consistency of the sensitivity.

[0035] In actual application, the position between the sealing structure 10 and the control plate 21 may change due to factors such as assembly error and accumulated tolerance, for example, the distance between the sealing structure 10 and the control plate 21 increases, at this time, the elastic protrusion 11 can restore at least part of the elastic deformation to absorb the above-mentioned assembly error, accumulated tolerance and the like, and the sealing structure 10 can keep abutting against the control plate 21 at all times, which will avoid the gap between the sealing structure 10 and the control plate 21 due to the position change to cause airflow leakage, and in turn cause the sensitivity of the airflow sensor 22 to be insufficient or inconsistent due to the airflow leakage.

[0036] In an embodiment, the airflow sensor 22 is fixedly arranged on the control plate 21, for example, the airflow sensor 22 is welded on the control plate 21, at this time, when the airflow sensor 22 senses airflow change, it can quickly convert these changes into an electrical signal to feed back to the control plate 21, and timely control the working of the atomization device through the control plate 21, thereby improving the sensitivity of the airflow sensor 22.

[0037] In an embodiment, as shown in Figure 3 , the elastic protrusion 11 is in a prism structure, the upper base of the prism structure is provided with the mounting hole 12, and the prism structure abuts against the control plate 21.
