Atomizer and electronic atomization device

The utility model relates to an atomizer and an electronic atomization device. The atomizer comprises a smoke cartridge tube, a shell, a switch piece and a heating assembly. An oil bin, an atomization channel and a liquid inlet channel are formed in the smoke cartridge pipe, the switch piece is arranged at the communicating opening of the oil bin and the liquid inlet channel of the smoke cartridge pipe, the oil bin and the liquid inlet channel are selectively communicated or blocked through the switch piece, and after the oil bin and the liquid inlet channel are blocked through the switch piece, no gap exists between the oil bin and the liquid inlet channel; at the moment, the aerosol generating matrix in the oil bin cannot be extruded out due to temperature rise and air expansion, the stability of the electronic atomization device is improved, and it is guaranteed that the electronic atomization device can be normally used in various environments. 本申请涉及一种雾化器及电子雾化装置，雾化器包括：烟弹管、外壳、开关件以及发热组件。烟弹管内部形成油仓、雾化通道以及进液通道
