The liquid supply has a liquid chamber. The liquid supply includes a sealing piece at an end, and the sealing piece defines a liquid outlet. The atomizing assembly includes a connecting part. The liquid supply includes an engaging part. The engaging part includes a rotary sealing element rotatable relative to the sealing element. When the liquid supply and the atomizing assembly are disassembled, the rotary sealing element seals the liquid outlet. When the connecting part is inserted into the engaging part and rotated a first angle, the atomizing assembly and the liquid supply are engaged. When the atomizing assembly is further rotated a second angle, the atomizing assembly drives the rotary sealing element to rotate to open the liquid outlet, and the tobacco liquid in the liquid chamber flows into the atomizing assembly. ## Claims ### Claim 1 An atomizer comprising: a liquid supply and an atomizing assembly detachably connected with the liquid supply, the liquid supply having a liquid chamber configured for storing tobacco liquid, the liquid supply comprising a sealing piece at an end, the sealing piece defining a liquid outlet; wherein the atomizing assembly comprises a connecting part, the liquid supply comprises an engaging part matching with the connecting part, the engaging part comprises a rotary sealing element rotatable relative to the sealing element, when the liquid supply and the atomizing assembly are disassembled, the rotary sealing element seals the liquid outlet; when the connecting part is inserted into the engaging part and rotated a first angle, the atomizing assembly and the liquid supply are engaged to form a snap fit connection; when the atomizing assembly is further rotated a second angle relative to the liquid supply, the atomizing assembly drives the rotary sealing element to rotate to open the liquid outlet, so that the tobacco liquid in the liquid chamber flows into the atomizing assembly via the liquid outlet. ### Claim 2 (depends on 1) The atomizer according to claim 1, wherein the rotary sealing element is made of resilient material, and abuts against the sealing piece, the rotary sealing element defines a liquid hole, and the liquid hole is selectively in alignment with the liquid outlet during rotation of the rotary sealing element. ### Claim 3 (depends on 2) The atomizer according to claim 2, wherein the connecting part defines a liquid inlet, when the atomizing assembly is inserted into the liquid supply, and rotated a first angle, the liquid inlet is in alignment with the liquid hole. ### Claim 4 (depends on 3) The atomizer according to claim 3, wherein the rotary sealing element comprises a plurality of sealing ribs provided on a surface facing the atomizing assembly, and the sealing ribs surround the liquid holes. ### Claim 5 (depends on 3) The atomizer according to claim 3, wherein the atomizing assembly comprises at least one liquid conducting component and a heating element in contact with the at least one liquid conducting component, and the at least one liquid conducting component is configured for absorbing the tobacco liquid and conveying the tobacco liquid to the heating element for atomization. ### Claim 6 (depends on 1) The atomizer according to claim 1, wherein the liquid supply further comprises a tubular element in the liquid chamber and a mouthpiece, the tubular element is hollow and allows air to flow therethrough, the sealing piece is fixed at a first end of the tubular element, the rotary sealing element is rotatably coupled to the first end, and the mouthpiece is connected with an opposite second end of the tubular element. ### Claim 7 (depends on 6) The atomizer according to claim 6, wherein the connecting part defines an aerosol outlet, and the aerosol outlet communicates with the tubular element. ### Claim 8 (depends on 1) The atomizer according to claim 1, wherein the engaging part further comprises a connecting rotor fixedly connected with the rotary sealing element, the connecting rotor comprises an engaging part formed on a sidewall thereof; the connecting part defines an inserting opening and an arc-shaped groove, and the engaging part is engaged in the arc-shaped groove to form the snap fit connection. ### Claim 9 (depends on 1) The atomizer according to claim 1, wherein the first angle and the second angle are both 90 degrees. ### Claim 10 (depends on 1) An electronic cigarette, comprising: an atomizer according to claim 1; and a power supply configured for supplying the atomizer power, a first end of the atomizing assembly being connected with the liquid supply, an opposite second end of the atomizing assembly being connected with the power supply.
