  • Patent number: 11103660
    Abstract: An atomizer comprises an outer tube, a liquid storing member received in the outer tube, and an atomizing head located at the lower portion of the liquid storing member. A liquid storing cavity is formed in the liquid storing member. An air outlet channel is formed between the outer tube inner wall and the liquid storing member outer wall. An atomizing cavity communicating with the liquid storing cavity and the air outlet channel is formed in the atomizing head. When the liquid tobacco absorbed by the atomizing head is insufficiently atomized, the liquid storing member above the atomizer head acts as a stopper, small smoke droplets can only be released from both sides of the atomizing head, preventing user inhalation of non-atomized liquid. An electronic cigarette having the atomizer is also provided.

  • Patent number: 11077264
    Abstract: An electronic cigarette includes a liquid storage device a liquid storage chamber, an atomizing device comprising an atomizing chamber, a controller, and a driving mechanism. The driving mechanism is electrically connected to the controller. When the controller controls the liquid intake of the electronic cigarette, the controller controls the driving mechanism to drive the e-cigarette liquid in the liquid storage chamber to enter the atomizing chamber, thereby realizing the control of the amount of the e-cigarette liquid in the atomizing device. In use, the electronic cigarette is provided with a proper amount of e-cigarette liquid in the atomizing device, and there is no dry burning or liquid leakage due to insufficient atomization.

  • Patent number: 10932498
    Abstract: An atomizing head and a ventilation assembly are included in an atomizer for an electronic cigarette. The atomizing head includes an atomizing core and an atomizing tube. The circumference of the atomizing core defines airflow channels, so that air can flow into the atomizing core. This avoids the leakage caused by negative pressure when a user is inhaling smoke. The atomizer causes outside air to be more fully mixed with the smoke generated from liquid tobacco, and the user's experience is improved.

  • Publication number: 20210007402
    Abstract: A control method and device, and an electronic cigarette. The method includes: obtaining the maximum output power during the secure output of an atomizer connected to a body; detecting whether the currently-set target power of the atomizer is higher than the maximum output power; and if the target power is higher than the maximum output power, executing a preset operation, the preset operation including at least one of controlling, the atomizer to output at power lower than or equal to the maximum output power and displaying a first reminder message, according to a cigarette lighting signal. The method resolves the problem that dry burning would easily occur in an atomizer, and has the function of protecting the atomizer and preventing the shortening of the life of a heating component caused by the burning of the heating component due to high power output of the atomizer.
