Atomizer and electronic cigarette having same

Abstract

An exemplary atomizer includes a housing, a solution reservoir, and an atomizing part. The housing defines an air inlet, an air outlet, and an air passage communicating the air inlet and the air outlet. The solution reservoir is received in the housing and is configured for reserving tobacco solution. The atomizing part is configured for atomizing the tobacco solution. The atomizing part includes an atomizing cup with an atomizing cavity, and an atomizing unit received in the atomizing cavity. The atomizer further includes a first solution conducting component between the solution reservoir and the atomizing part. The first solution conducting component is configured for conveying the tobacco solution from the solution reservoir to the atomizing cup for atomization. The first solution conducting component includes a porous ceramic body. The tobacco solution is absorbed and stored in the porous ceramic body, and is then conveyed to the atomizing unit for atomization.
