摘要： Provided is a cigarette mouthpiece, a cartomizer and an electronic cigarette therefor. The cigarette mouthpiece includes a hard substrate and a soft substrate mounted on the outside of the hard substrate. A through hole is defined inside the hard substrate and extends through two opposite ends of the hard substrate. When a user's lips come in contact with the cigarette mouthpiece, the user's lips can obtain soft and comfortable tactility by providing the soft substrate on the hard substrate. At the same time, the use of the hard substrate in cooperation with the soft substrate ensures the reliability of the cigarette mouthpiece, reduces the risk of contamination and prolongs the service life.

摘要： A method and a device for controlling electronic cigarette belong to the technical field of computers. The method comprises: when a safety mode of electronic cigarette is turned on, if a cigarette lighting signal is detected, using a detection component to detect whether an atomizing head is moved out of an electronic cigarette body; if detecting that the atomizing head is moved out of the electronic cigarette body, stopping controlling the atomizing head to work according to the cigarette lighting signal, wherein when the atomizing head is moved out of the electronic cigarette body, the atomizing head is still electrically connected to battery assembly in the electronic cigarette. The method and the device solve the problem that electronic cigarette user mistakenly triggers lighting operation and causes to burn user when the atomizing head is exposed outside the electronic cigarette body, which achieving safe use effect of electronic cigarette.

摘要： A cartridge includes a liquid storage assembly, a connecting assembly, and an atomizing assembly. The connecting assembly is connected to the lower end of the liquid storage assembly. The atomizing assembly is received in the connecting assembly. The atomizing assembly includes an atomizing base, a liquid absorbing member, and a heating member. The upper end surface of the atomizing base is recessed downward to form a mounting groove. The liquid absorbing member is received in the mounting groove. The heating member is located above the mounting groove of the atomizing base corresponding to the liquid absorbing member, and the heating member presses and fixes the liquid absorbing member in the mounting groove. The liquid storage chamber is in fluid communication with the liquid absorbing member. The cartridge is convenient to replace the entire atomizing assembly or replace the liquid absorbing member and the heating member individually.

摘要： An atomizer and an aerosol generating device are provided. The atomizer includes a liquid storage member with a liquid storage cavity formed therein for storing an aerosol-forming substrate; and an atomizing housing at least partially received in the liquid storage cavity. A liquid storage space is formed inside the atomizing housing. The atomizing housing is provided with an air guiding hole configured for communicating an upper portion of the liquid storage space with an outside atmosphere. The atomizing housing is further provided with a pressure relief hole communicating the liquid storage space with the liquid storage cavity. When an air pressure in the liquid storage cavity is greater than an external air pressure and a positive pressure difference is formed, the aerosol-forming substrate in the liquid storage cavity is squeezed by the positive pressure difference into the liquid storage space through the pressure relief hole.
