Throttling device suitable for gas inlet of smoke generator cavity of electronic smoking set

The invention relates to a throttling device (100) suitable for a gas inlet of a smoke generator cavity of an electronic smoking set. The throttling device (100) comprises a body (101) and a throttling component (104), the body is a regular cylinder, the outer outline of the body is matched with the inner outline of the gas inlet of the smoke generator cavity, and conical cavities (102) are formed in the upper end and the lower end of the body (101) respectively. The throttling component (104) is located in the axial middle of the body and is communicated with the two conical cavities (102), and the throttling component (104) is a reducing pipeline type throttling component, or a pipeline type throttling component, or a capillary type throttling component or a centre type throttling component, wherein a pipeline of the pipeline type throttling component comprises at least one bent part. The cone top ends of the conical cavities in the two ends are each provided with a hole, the caliber of the holes is equal to that of openings of the throttling component, and the holes serve as connectors where the two conical cavities are communicated with the throttling component. The portions between the body and the conical cavities in the two ends as well as between the body and the throttling component are filled with heat insulation materials. The throttling device suitable for the gas inlet of the smoke generator cavity of the electronic smoking set is suitable for electrical heating non-combustion cigarettes.
