摘要： The present invention discloses an atomizer and an atomizing assembly, including an adsorption substrate, a heating member, and a lead. The adsorption substrate is configured to adsorb a liquid atomizable medium, the heating member includes a heating body and an electrode connected with the heating body, and the heating body is disposed on a sidewall of the adsorption substrate. The electrode is partially or completely embedded in the adsorption substrate, and the lead is electrically connected with a portion of the electrode that is located in the adsorption substrate. Since the electrode extending from the heating body is partially or completely embedded in the adsorption substrate, and one end of the lead is embedded in the adsorption substrate, the adsorption substrate wraps the electrode and part of the lead of the heating member; due to that the heating body is poor in strength and easy to be deformed, while the structural strength of the electrode is good, the electrode can be embedded in the porous ceramic, so that the heating body of the heating member is not prone to being deformed due to the pulling of the lead during the assembly process, thereby avoiding the problem of core overburning because of the separation of the heating member and the adsorption substrate.

摘要： The present invention discloses an electronic atomizer, including a liquid storage unit, an atomization unit arranged at a rear side of the liquid storage unit, a gas supply unit supplying gas to the liquid storage unit, and a control unit controlling operation of the atomization unit and the gas supply unit. The liquid storage unit includes a liquid storage compartment, and a sealing member is arranged between the liquid storage compartment and the atomization unit. The sealing member hermetically seals the liquid storage compartment. The sealing member is formed with a gas conducting hole through which an atomized gas is conducted out, at least one liquid ingress one-way valve, and at least one gas ingress one-way valve. The liquid ingress one-way valve controls liquid of the liquid storage compartment to move, in a one-way manner, into the atomization unit for atomization. The gas ingress one-way valve is connected to the gas supply unit to supply gas, in a one-way manner, into the liquid storage compartment. The present invention provides that the gas supply unit functions for feeding gas to open the gas ingress one-way valve in order to charge gas into the liquid storage compartment to make the gas pressure inside the liquid storage compartment greater than a gas pressure of the atomization unit to thereby open the liquid ingress one-way valve to have the atomizable liquid flowing to the atomization unit. When not in operation, the atomizable liquid in the liquid storage compartment is not in direct contact with the atomization unit so as to avoid liquid leaking.
