Description

Heating non-combustion device Technical Field The application relates to the technical field of aerosol generation, in particular to a heating non-combustion device. Background The heating non-combustion device is an appliance for heating an aerosol-generating substrate by means of its own heating element and using the heating non-combustion principle, thereby generating an aerosol. Tightness is one of the properties of great concern for heating non-combustion devices. Good air tightness is a key factor for guaranteeing the efficient and stable operation of the heating non-combustion device. Once the air tightness is poor, on one hand, the generation quality of aerosol can be influenced, so that the concentration of the aerosol and the like deviate from ideal conditions, the use experience of a user is influenced, and on the other hand, the service life of the heating non-combustion device can be also influenced.
