Electronic cigarette case

1. An electronic cigarette case comprising

a case body,

a case lid hinged with the case body via a rotating axis,

a control unit configured in the case body,

a switch configured on the outside of the case body and electrically connected with the control unit,

a location-limited switch configured in the case body and electronically connected with the control unit,

a flipping mechanism, and

a driving motor electrically connected with the control unit;

wherein, one end of the flipping mechanism is connected to a shaft of the driving motor, and the other end of the flipping mechanism is embedded into the case lid slidably; the driving motor is controlled by the control unit to drive the flipping mechanism to rotate towards the opening or closing direction, so as to open or close the case lid;

wherein, the electronic cigarette case is configured to accommodate an electronic cigarette comprising an atomization assembly and a battery assembly, a first seat and a second seat for respectively placing the atomization assembly and the battery assembly are defined in the case body, and the battery assembly is connected to and charged by the control unit via a spring plate when the battery assembly is placed in the second seat;

wherein, the flipping mechanism comprises a worm screw mounted on the shaft of the driving motor, a gear engaged with the worm screw, and a curved bar; the curved bar includes a straight portion and an arced portion formed with the straight portion integrally, the straight portion is connected to the gear, and the arced portion is attached to an inner side wall of the case lid slidably; and

wherein, the curved bar is configured to press the location-limited switch when the case lid is closed and then the driving motor can be controlled to stop rotating by the control unit.

2. The electronic cigarette case of claim 1 , wherein, a curved bar chute is defined in the inner side wall of the case lid close to the rotating axis, and the arced portion of the curved bar is attached to the curved bar chute slidably and location-limited by the curved bar chute.

3. The electronic cigarette case of claim 2 , wherein, the straight portion is configured to be a radius of the arced portion.

4. The electronic cigarette case of claim 1 , wherein, a groove for limiting the location of a gear rotating axis of the gear is provided in the case body, and the gear rotating axis is attached to the groove so as to prevent the location of the gear deviated during rotation.

5. The electronic cigarette case of claim 1 , wherein, the control unit is configured as a control printed circuit board with timing function, which can be used to control the driving motor to operate during a predetermined period when the case lid is opened and to stop rotating after the period has been exceeded.

6. The electronic cigarette case of claim 1 , wherein, a first hinge part is configured on the case lid, a second hinge part is configured on the case body; a first through hole is defined in the first hinge part, and, a second through hole which has a same axis with the first through hole is defined in the second hinge part; the rotating axis is inserted into the first and second through holes.

7. The electronic cigarette case of claim 6 , wherein, the first through hole is matched with the rotating axis with a first gap, and the second through hole is matched with the rotating axis with a second gap.

8. The electronic cigarette case of claim 6 , wherein, the first hinge part comprises an arc-shaped structure, and the first hinge part is contacted with the case body slidably when the case lid is opened or closed.

9. The electronic cigarette case of claim 7 , wherein, the first hinge part comprises an arc-shaped structure, and the first hinge part is contacted with the case body slidably when the case lid is opened or closed.

10. The electronic cigarette case of claim 1 , wherein, the gear is mounted between the worm screw and the inner surface of the case lid close to the worm screw.

11. The electronic cigarette case of claim 5 , wherein, the gear is mounted between the worm screw and the inner surface of the case lid close to the worm screw.
