## Abstract

An electronic cigarette includes a main body, a control assembly, at least two clearomizers, and a sliding member. The at least two clearomizers and the sliding member are disposed on the main body. The sliding member is slidable on the main body to drive the control assembly to control the operation of the at least two clearomizers.

## Claims

### Claim 1

An electronic cigarette, comprising a main body, a control assembly, two clearomizers, and a sliding member; wherein:
the two clearomizers and the sliding member are disposed on the main body;
the sliding member is slidable along a movement line on the main body to drive the control assembly to control operations of the two clearomizers;
each of the two clearomizers comprises an air hole;
the main body comprises two air inlets, each of the two air inlets communicating with one air hole;
the two air inlets are disposed along the movement line;
the sliding member is configured to slide to cover and/or expose the two air inlets;
the control assembly comprises a control board, two semiconductor switches, and two magnetic members;
the two semiconductor switches are disposed on the control board along the movement line, and abut against the sliding member;
the two magnetic members are disposed on the sliding member along the movement line; and
the sliding member is configured to slide along the movement line towards one semiconductor switch, whereby one magnetic member is disposed above the one semiconductor switch, magnetism of the one magnetic member causes a change in a potential difference of the one semiconductor switch, and the one semiconductor switch is turned off to prevent the operation of one clearomizer.

### Claim 2 (depends on 1)

The electronic cigarette of claim 1, wherein the main body further comprises a first housing comprising two chambers configured to accommodate the two clearomizers respectively.

### Claim 3 (depends on 2)

The electronic cigarette of claim 2, wherein the first housing comprises a sliding groove; the sliding member is disposed in the sliding groove to slide back and forth within the sliding groove; the two air inlets are disposed on a wall of the sliding groove; the main body further comprises a second housing disposed outside of the first housing; the second housing comprises a through hole matched with the sliding groove; the sliding member is disposed through the through hole or a slide switch is disposed in the through hole to connect to the sliding member.

### Claim 4 (depends on 1)

The electronic cigarette of claim 1, wherein each of the two clearomizers comprises an airflow channel, and the control assembly further comprises a pneumatic switch disposed in the airflow channel or in the air hole.

### Claim 5 (depends on 1)

The electronic cigarette of claim 1, wherein each of the two clearomizers comprises an electrical heating element, and resistances of electrical heating elements of the two clearomizers are different from each other.

### Claim 6 (depends on 1)

The electronic cigarette of claim 1, wherein a mouthpiece is disposed on the main body and communicates with each of the two clearomizers; the mouthpiece is detachably connected to the main body and the two clearomizers are detachably disposed in the main body.
