Zusammenfassung:	The present disclosure is directed to an air vent assembly (100), including an air vent assembly for a pump of an oral irrigator. The air vent assembly comprises a first internal chamber (144) in fluid communication with the input port (104) and the outlet port (106) and arranged to receive a fluid or a gas. The first internal chamber comprises: a first inner surface (168) having a first inner surface portion (170) and a second inner surface portion (172); a first valve (134) comprising an expandable element (178), the first valve arranged to transition from an open state to a closed state; and an exit channel (146) in fluid communication with the first internal chamber, and arranged between the second inner surface portion of the first inner surface and the outlet port. In the closed state, the first valve is arranged to contact the first exit aperture and impede a flow of the fluid or gas into the exit channel.
