Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of electronic heating appliances, and particularly relates to a non-combustion tobacco heating appliance. BACKGROUND

[0002] As a substitute for traditional cigarettes, the heat-not-burn tobacco has rapidly attracted people's attention and favor due to its safety, convenience, health, environmental protection and other advantages, and the performance of the heat-not-burn tobacco appliance as the only smoking tool for the tobacco directly affects the overall smoking quality of the heat-not-burn tobacco.

[0003] In the process of smoking the low-temperature non-combustion tobacco, an external heating device, i.e., the heat-not-burn tobacco appliance, is needed.

[0004] A heat-not-burn tobacco appliance and a tobacco extraction mechanism thereof are disclosed in Chinese patent (CN109497625A), wherein the tobacco extraction mechanism includes a tobacco container, an elastic clamping cup for clamping or releasing the tobacco, and a clamping plate for clamping or releasing the elastic clamping cup. The elastic clamping cup is inserted into the tobacco container and partially extends out of the tobacco container. The clamping plate is arranged on the outside of the elastic clamping cup. When the tobacco is pulled out, the tobacco drives the elastic clamping cup to move upward, so that the elastic clamping cup is separated from the clamping plate, the tobacco is released, and the tobacco is moved away from the heating device of the heat-not-burn tobacco appliance, thereby completing the separation of the tobacco and the heating rod.

[0005] However, in actual use, since the tobacco and the heating rod only move relatively upward and downward, the tobacco in the tobacco is still likely to be left on the heating rod, which affects the next use of the appliance. SUMMARY
