Abstract: A method for controlling the temperature of a vaporizer for an inhaler, in particular an electronic cigarette product, comprising the steps of measuring the voltage applied to a heating element; measuring the current flowing through the heating element; determining the resistance of the heating element from the measured voltage and the measured current; controlling the temperature of the heating element by switching off the switching element in a controlled manner so that the current flow through the heating element is interrupted when the determined resistance exceeds or falls below a first critical threshold R_co.

Abstract: A fluid pump for pumping a fluid from an inlet toward an outlet comprises a pump body, a pump diaphragm, and a valve seat. The pump body has a first opening and a second opening. The pump diaphragm is attached to the pump body and forms a pump chamber between the pump body and the pump diaphragm. The pump chamber is fluidly connected to the inlet by the first opening and to the outlet by the second opening. The valve seat is disposed inside the pump chamber and around the second opening. The valve seat protrudes with an undeformed height from the second opening into the pump chamber in a direction toward the pump diaphragm. The valve seat has an elastic body and a gasket with a sealing surface. The pump diaphragm is deflectable and is adapted to open and close a fluidic pathway of the outlet by moving into and out of contact with the valve seat.
