Abstract: A vaporizer includes: a liquid storage housing; a liquid storage member disposed in the liquid storage housing; a vent tube passing through the liquid storage member; an end cap covering an end of the liquid storage housing; and an air-pressure balance channel communicating the liquid storage member with the outside.

Abstract: A vaporizer includes a liquid storage space, an airflow channel, an end cap and a liquid absorbing member. The end cap includes a supporting surface and one end of the liquid storage space is covered by the end cap. The vent hole is in communication with the airflow channel. The liquid absorbing member is arranged on the supporting surface of the end cap. The liquid absorbing member includes an air outlet hole in communication with the vent hole. The supporting surface of the end cap includes a plurality of liquid guide grooves. Each of the plurality of liquid guide grooves is in contact with the liquid absorbing member.

Abstract: A composite liquid guide cotton for a vaporizer includes: at least one heat resistant layer, at least one first isolation layer, at least one rapid liquid guide layer, and at least one second isolation layer that are stacked in sequence. The heat resistant layer contacts a heating body and comprises a high-temperature resistant material. A liquid guide rate of the rapid liquid guide layer is higher than a liquid guide rate of the first isolation layer and the second isolation layer.

Abstract: A vaporizer includes: a liquid storage shell, a liquid storage space and an airflow channel being formed within the liquid storage shell; an end cap covering one end of the liquid storage space, a vent hole in communication with the airflow channel being formed on the end cap; and a liquid absorbing member arranged on the end cap, an air outlet hole in communication with the vent hole being formed on the liquid absorbing member. The end cap includes a supporting surface for contact with the liquid absorbing member. At least one first liquid guide groove is provided on the supporting surface. Each of the at least one first liquid guide groove comprises a first end in communication with the vent hole and a second end away from the vent hole.

Abstract: An atomizer includes: a liquid storage housing; and a first end cap provided in the liquid storage housing. A liquid storage space and an airflow channel are formed in the liquid storage housing, and one end of the liquid storage space is covered by the first end cap. At least one capillary channel is provided on the first end cap, the at least one capillary channel being separately in communication with the airflow channel and the liquid storage space.
