Abstract

The present application relates to an atomizer and an electronic atomizing device. An atomizer includes a housing provided with air inlets and air outlets oriented differently, and an air flow passage communicating between the air inlets and the air outlets, the air flow passage including an air inlet passage and an atomization zone communicating with each other, wherein the air inlet passage is configured to curve from an end near the air inlets to an end near the atomization zone. By utilizing the atomizer, the generation of vortex can be reduced, so that the energy loss of air flow is smaller, aerosol on the side wall of the atomization area is taken away in the process that the air flow flows from the atomization area to the air outlet, and the aerosol can be absorbed more easily due to smaller air flow resistance.
