Electronic cigarette case
An electronic cigarette case includes a box body, a box cover hinged to the box body and an opening and closing mechanism. The opening and closing mechanism includes a spring piece built in the box body and an arc-shaped bulge formed on the box cover. The arc-shaped bulge clamped between the spring piece and inner wall of the box body and slidingly contact with the spring piece. When the box cover rotates a first predetermined angle relative to the box body, the spring piece drives the bulge to slide relative to the spring piece until the box cover is fully open. When the box cover rotates a second predetermined angle relative to the box body, the spring piece drives the arc-shaped bulge to slide relative to the spring piece until the box cover is fully closed. Thus, it is convenient to open or close the electronic cigarette case which has a simplified structure.
1. An electronic cigarette case, comprising a box body ( 1 ), a box cover ( 2 ) hinged to the box body ( 1 ), and an opening and closing mechanism, the opening and closing mechanism including a spring piece ( 31 ) built in the box body ( 1 ) and an arc-shaped bulge ( 33 ) formed on the box cover ( 2 ), the arc-shaped bulge ( 33 ) clamped between the spring piece ( 31 ) and an inner wall of the box body ( 1 ) and slidingly contacting with the spring piece ( 31 );
wherein when the box cover ( 2 ) rotates a first predetermined angle relative to said box body ( 1 ), the spring piece ( 31 ) pushes the arc-shaped bulge ( 33 ), which makes the arc-shaped bulge ( 33 ) slidingly contacting relative to the spring piece ( 31 ) until the box cover ( 2 ) is fully open;
when the box cover ( 2 ) rotates a second predetermined angle relative to the box body ( 1 ), the spring piece ( 31 ) pushes the arc-shaped bulge ( 33 ), which makes the arc-shaped bulge ( 33 ) slidingly contacting relative to the spring piece ( 31 ) until the box cover ( 2 ) is fully closed;
said opening and closing mechanism further comprises a spring ( 32 ) built in the box body ( 1 ) horizontally, and two ends of the spring ( 32 ) are fixed to the box body ( 1 ) and the spring piece ( 31 ) respectively; and
the spring piece ( 31 ) comprises a bending part ( 311 ), a part of said bending part ( 311 ) protrudes to form a bridge-shaped fixing position ( 312 ), and an end of the spring ( 32 ) passes through the bending part ( 311 ) and is secured to the spring piece ( 31 ).
2. The electronic cigarette case of claim 1 , characterized in that the spring piece ( 31 ) further comprises a connection part connected to the bending part ( 311 ), the spring ( 32 ) is perpendicular to said connection part.
3. The electronic cigarette case of claim 2 , characterized in that the spring piece ( 31 ) is secured to interior of the box body ( 1 ) via at least one screw(s).
4. The electronic cigarette case of claim 3 , characterized in that the electronic cigarette case further comprises an needle shaft ( 4 ), a first hinge joint part ( 21 ) is formed on the box cover ( 2 ), a second hinge joint part ( 11 ) is formed on said box body ( 1 ) and is inserted by the first hinge joint part ( 21 ), a first through-hole is defined in the first hinge joint part ( 21 ), a second through-hole ( 21 ) being coaxial to the first through-hole is defined in the second hinge joint part ( 11 ), and the needle shaft ( 4 ) inserts into the first through-hole and the second through-hole.
5. The electronic cigarette case of claim 4 , characterized in that the cooperation among the needle shaft ( 4 ), the first through-hole and the second through-hole is implemented via gaps among the needle shaft ( 4 ), the first through-hole and the second through-hole.
6. The electronic cigarette case of claim 4 , characterized in that a V-shaped bulge ( 12 ) is formed on the second hinge joint part ( 11 ), a V-shaped recess ( 22 ) formed on the first hinge joint part ( 21 ) has a bigger opening angle than the V-shaped bulge ( 12 ), and the V-shaped bulge ( 12 ) is embedded into the V-shaped recess ( 22 ).
7. The electronic cigarette case of claim 6 , characterized in that a fillet chamfer ( 23 ) is formed on the lateral of the V-shaped recess ( 22 ).
