1. An atomizing assembly for an inhaler, comprising:

  • a housing defining an airflow channel therein and comprising a reservoir surrounding the airflow channel for storing liquid; and

    an atomizing core coupled to the housing and comprising a core body, an exhaust pipe, and an atomizing element, the core body defining an atomizing chamber therein, the core body further defining an inlet and an outlet thereon in fluid communication with the atomizing chamber, the exhaust pipe being located at the outlet, the atomizing element being received in the atomizing chamber and being configured to atomize the liquid;

    wherein the core body further defines a liquid absorbing hole in fluid communication with the atomizing chamber and the reservoir, the atomizing element is in contact with the liquid in the reservoir via the liquid absorbing hole, the exhaust pipe extends at least partially into the airflow channel, the exhaust pipe defines a through hole or notch on a sidewall thereof which is in fluid communication with an interior of the exhaust pipe and the airflow channel;

    wherein the housing comprises a first tubular structure and a second tubular structure, the first tubular structure has a greater diameter than a diameter of the second tubular structure, the second tubular structure is located inside the first tubular structure, the airflow channel is formed by an interior of the second tubular structure, the reservoir is formed between the second tubular structure and the first tubular structure;

    wherein the atomizing core further comprises a sealing member sleeved on the exhaust pipe;

    the sealing member is located between the exhaust pipe and the second tubular structure and abuts an inner sidewall of the second tubular structure;

    a portion of the exhaust pipe extends out of the sealing member;

    the through hole is located at a portion of the exhaust pipe extending out of the sealing member and is adjacent to the sealing member.
