摘要： A cartridge includes a cartridge housing, an atomizing head, and a sealing member. A liquid storage cavity for storing e-liquid is formed inside the cartridge housing. The atomizing head is located at one end of the cartridge housing, and the sealing member is located at the other end of the cartridge housing opposite to the atomizing head. The atomizing head is in communication with the liquid storage cavity and the outside. When a liquid injection needle is used to inject liquid into the cartridge, the liquid injection needle pierces the sealing member and extends into the cartridge housing to inject e-liquid into the liquid storage cavity. The air in the liquid storage cavity is discharged out through the end of the cartridge housing with the atomizing head. After the liquid injection needle is pulled out, the sealing member will form a self-sealing at the pierced position.

摘要： An atomizer includes a housing, an atomizing assembly and a movable assembly. The housing defines a mounting opening. The atomizing assembly includes an inner tube detachably mounted in the housing through the mounting opening. The inner tube is provided with a smoke outlet. The movable assembly includes a dustproof cover movably disposed on the housing and a locking member. The dustproof cover is rotatable relative to the locking member, rotating the dustproof cover can open the mounting opening to expose the smoke outlet or close the mounting opening to cover the smoke outlet. The inner tube is provided with a locking groove engaged with the locking member. When the dustproof cover opens the mounting opening and the dustproof cover is caused to slide, the locking member moves under the driving of the dustproof cover to disengage from the locking groove, such that the inner tube can be taken out.

摘要： An e-liquid supply method and device and an aerosol generating device. The e-liquid supply method includes: obtaining a real-time temperature of a heating member of the aerosol generating device every first preset period after lighting (S110); if, in a second preset period after lighting, at least one real-time temperature change value of the heating member is not less than a temperature change threshold, supplying a e-liquid for the first time (S120), wherein the time length of the second preset period is greater than the time length of the first preset period; and, after supplying of the e-liquid for the first time, supplying the e-liquid in real time according to an e-liquid supply amount corresponding to the real-time temperature of the heating member (S130). It can avoid e-liquid spitting or spilling due to excessive liquid supply, and also avoid dry burning or a paste smell caused by insufficient liquid supply.

摘要： A heating mechanism of an electronic cigarette includes a heating member defining an airflow passage for airflow passing through; a liquid guiding member for absorbing and/or storing tobacco liquid for the heating member to perform an atomizing action; and a base seat, wherein both the heating member and liquid guiding member are assembled to the base seat. The base seat made of ceramic material can retain an atomizing temperature, causing the flavor of the next smoke to be same as the previous one smoke. Because the base seat made of ceramic material has a high temperate resistance, a flavor cannot be influenced by avoiding a dry-fried due to an appropriate assembly. Further, the base seat made of ceramic material can absorb a part or all the tobacco liquid condensed and received in the atomizing chamber, when the atomizer is used again, the fried oil can be avoided.

摘要： Disclosed are a cartridge and an electronic cigarette having the cartridge. The cartridge includes a liquid storage cavity, an atomizing cavity, a liquid suction member, a liquid outlet, a smoke outlet, and an air inlet opening. Before the cartridge is used, the liquid outlet is in a closed state, such that e-liquid in the liquid storage cavity is isolated from the liquid suction member. When the cartridge is used, the liquid outlet is in an open state, such that the e-liquid in the liquid storage cavity flows out through the liquid outlet. The atomizing cavity is provided with an opening, and the size of the heating member matches the size of the opening; and when the cartridge is used, the heating member extends into the atomizing cavity through the opening and comes into contact with the liquid suction member or stays a preset distance away from the liquid suction member.
