HEATING APPARATUS AND LOW-TEMPERATURE NON-BURNING SMOKING SET

The present invention relates to a heating apparatus and a low-temperature non-burning smoking set. The heating apparatus comprises a heating body and a support. The heating body is mounted at one end of the support. The support is provided with a first through groove. The heating body is used for generating heat and is provided with at least one second through groove, each second through groove is in communication with the first through groove, and the sum of the cross-sectional areas of all the second through grooves is greater than the cross-sectional area of one end of the first through groove that is away from the second through grooves, such that the flow rate of a gas is reduced after entering the second through grooves from the first through groove, such that a period of time for which the gas passes through the second through grooves is prolonged without needing to increase the length of the heating apparatus. The heating apparatus has a small structure and less heat loss, and by means of providing t
