Description

Atomizer and electronic cigarette Technical Field The embodiment of the invention relates to the field of electronic cigarettes, in particular to an atomizer and an electronic cigarette. Background Electronic cigarettes are a product that allows a user to inhale after heating and atomizing a liquid substrate containing nicotine into aerosol. The part of the electronic cigarette realizing the atomizing function is an atomizer, and the electronic cigarette structurally comprises a liquid storage cavity for storing liquid matrixes, a porous body for sucking the liquid matrixes from the liquid storage cavity and a heating body for heating and atomizing the liquid matrixes sucked by the porous body. Further, in order to form aerosol transmission in the sucking process, an air inlet hole for air inlet and a smoke transmission pipe for outputting the aerosol are arranged on the part, corresponding to the heating body, of the shell of the atomizer. In the process of sucking by a user, external air enters the atomizer from the air inlet hole and then carries aerosol to be output through the smoke transmission pipe, so that complete airflow circulation is formed. Due to the arrangement of the airflow circulation structure, liquid matrix seeping from the porous body in the using process of the atomizer and condensate formed after cooling in aerosol transmission formed by heating can flow out from the air inlet hole after accumulating in the atomizer, so that oil leakage and pollution are caused. Based on the above, as an improvement, a nebulizer having a structure for shielding an air inlet hole is proposed in the prior art 201820119392.7, and a blocking piece capable of projecting and covering the air inlet hole is used on a plane of the nebulizer in the axial direction, so as to shield the air inlet hole, thereby preventing the liquid substrate from flowing out. After the baffle plate structure is added, on one hand, the suction resistance is increased, and on the other hand, the external air flow entering through the air inlet hole becomes diffused, so that part of generated aerosol is diffused to the corner falling part to be retained, and the smoke outlet efficiency is reduced.
