Atomizer and electronic atomization device

The invention discloses an atomizer and an electronic atomization device.The atomizer comprises a liquid storage bin, an atomization assembly, a flow control assembly and an air pressure source, and the liquid storage bin is used for storing an aerosol generating substrate; the atomizing assembly is used for atomizing the aerosol generating substrate to generate aerosol; the flow control assembly is provided with a gas flow channel and a liquid flow channel; the liquid storage bin is communicated with the atomization assembly through a liquid flow channel; the gas flow channel and the liquid flow channel are provided with a common elastic side wall; the air pressure source is communicated with the air flow channel; the air pressure source is used for adjusting the air pressure in the air flow channel so that the public elastic side wall can deform towards one side of the air flow channel or the liquid flow channel, and therefore the flow of the aerosol generating matrix from the liquid storage bin to the atom
