An air passage fluidly connected to the atomizing assembly and a starting passage fluidly connected between the airflow passage and the puff sensor are defined in the electronic atomizing device. The starting passage defines a receiving groove for receiving a condensed aerosol. The condensed aerosol is received by the receiving groove when flowing into the starting passage, and is prevented from flowing into a main body to cause damage to elements such as the power supply, the puff sensor and a PCB therein, thereby extending the service life of the main body. ## Claims ### Claim 1 An electronic atomizing device, comprising an atomizing assembly and a puff sensor electrically connected with the atomizing assembly;
