Abstract
A heating device and a manufacturing method therefor, and a heat-not-burn smoking device. The heating device includes a first heating assembly, including a first housing configured for contacting with a tobacco, a first heating element on the first housing and configured to generate heat when electrified, and a first insulator between the first heating element and the first housing. The first heating element generates heat when electrified, the heat is conducted to the first housing through the first insulator, to heat but not burn the tobacco. The heating device is formed by cooperation of the heating element, the insulator and the housing, and heats the tobacco by the heating element when electrified. Compared with a heating conductive layer formed by a thick film printing process, the manufacturing of the heating device is simpler and more convenient, and the consistency and service life of the product are greatly improved.
