Each liquid inlet channel is provided with a liquid inlet hole 122, that is, each heating component 2 receives the atomized liquid in the liquid storage chamber 100 through two liquid inlet holes. 122 receives the atomized liquid in the liquid storage chamber 100. At this time, the range of the first spacing dimension C is 1-3 mm, and the ratio range of the second spacing dimension B and the first spacing dimension C is 1.2-4. Specifically, the two-input The liquid channel is arranged symmetrically, and the liquid inlet hole 122 is located at the bottom end of the liquid inlet channel.
