    Abstract: An exemplary liquid tank for an atomizer includes a bottom part, a liquid outlet, a first air inlet, a first porous liquid blocking element, and a top part. The bottom part has a first end and an opposite second end, and defines a liquid chamber for containing tobacco liquid. The liquid outlet is defined in the second end. The first air inlet is defined in the first end, so that external air can enter the liquid chamber via the first air inlet. The first porous liquid blocking element covers the first air inlet. The first porous liquid blocking element is capable of preventing the tobacco liquid in the liquid chamber from flowing out via the first air inlet, and allows air to pass through. The top part is detachably connected to the first end. The top part and the bottom part cooperatively clamp the first liquid blocking element therebetween.

    Abstract: An exemplary atomizer includes a liquid supply, an atomizing head, and an air passage. The liquid supply has a liquid chamber. The atomizing head includes a liquid absorbing element and a heating element. The liquid supply includes a sealing element at an end connected with the atomizing head. The sealing element is configured for sealing the tobacco liquid in the liquid chamber. The sealing element defines a through hole. The liquid supply further includes a magnet configured for sealing the through hole. The magnet abuts against the sealing element via a magnetic force. The atomizing head further includes an electromagnet. The electromagnet is configured for lifting the magnet when powered on, so that the tobacco liquid can flow out from the through hole. The present disclosure also relates to an electronic cigarette.

    Abstract: An atomizer includes a housing and a liquid storage cup. The housing has a mouthpiece thereon. The liquid storage cup is provided in the housing and configured for storing tobacco liquid. The liquid storage cup has an opening at one end thereof. A microporous liquid conducting body is plugged inside the opening for conducting the tobacco liquid in the liquid storage cup into an atomizing unit. An atomizing unit is connected to the opening and configured for heating the tobacco liquid to generate aerosol. An air flow channel is provided between the mouthpiece and the atomizing unit. The atomizing unit includes a support, a liquid guiding component located in the support, and at least one vertically arranged heating sheet. The heating sheet includes a side surface in contact with the liquid guiding component.

    Abstract: An electronic cigarette includes a housing, a sleeve, an atomizer, a latch assembly and a control assembly. The sleeve includes a first limiting position and a second limiting position. The atomizer includes a mouthpiece. The atomizer is capable of being inserted into the sleeve and telescoping relative to the sleeve along an axial direction of the sleeve, so as to expose the mouthpiece or take out the atomizer from the sleeve. The latch assembly is arranged on an end of the atomizer opposite to the mouthpiece and configured to latch the atomizer in the sleeve when the atomizer is retracted into the sleeve and is positioned at the first limiting position. The control assembly is arranged on the sleeve and configured to unlock the latch assembly to allow the end of the atomizer to move to the second limiting position along the axial direction of the sleeve.
