Abstract

The present disclosure provides an e-liquid bottle engageable with an electronic cigarette. The e-liquid bottle includes a main body ( 11 ), a cover ( 12 ), and a control switch ( 14 ); the cover ( 12 ) forms at least one liquid outlet ( 121 ); the control switch ( 14 ) is arranged in the cover ( 12 ). The electronic cigarette includes a cartridge ( 21 ) and a liquid injection device ( 23 ); the cartridge ( 21 ) forms a liquid reservoir (A), and one end of the cartridge ( 21 ) comprises an end wall ( 223 ) and a second operation portion ( 222 ) extending axially outwards from the end wall ( 223 ); the end wall ( 223 ) forms one liquid injection opening ( 2231 ), the second operation portion ( 222 ) corresponds to the control switch ( 14 ); the liquid injection device ( 23 ) is arranged on the end of the cartridge ( 21 ) and forms a liquid injection channel, and a first liquid inlet ( 2321 ) is formed in the liquid injection channel.

First claim

What is claimed is:

1. An atomizer, comprising a cartridge ( 21 ) and a liquid injection device ( 23 ); wherein,
a liquid reservoir (A) is defined in the cartridge ( 21 ), and the cartridge ( 21 ) comprises an end wall ( 223 ) which defines at least one liquid injection opening ( 2231 );
the liquid injection device ( 23 ) is arranged on the end of the cartridge ( 21 ) corresponding to the end wall ( 223 ), the liquid injection device ( 23 ) defines at least one liquid injection channel extending in the at least one liquid injection opening ( 2231 ), and a first liquid inlet ( 2321 ) is defined in the liquid injection channel; and

when the liquid injection device ( 23 ) is pressed inwards, the liquid injection channel moves inwards to communicate the first liquid inlet ( 2321 ) with the liquid reservoir (A); when the liquid injection device ( 23 ) is released, the liquid injection channel restores to its original position to block the first liquid inlet ( 2321 ) from the liquid reservoir (A).

2. The atomizer of claim 1 , wherein the liquid injection device ( 23 ) comprises a liquid injection tube ( 232 ) extending in the liquid injection opening ( 2231 ), and the liquid injection tube ( 232 ) defines the liquid injection channel.

3. The atomizer of claim 2 , wherein the first liquid inlet ( 2321 ) is defined in a side wall of the liquid injection tube ( 232 ).

4. The atomizer of claim 2 , wherein an outer wall of the liquid injection tube ( 232 ) engages with the liquid injection opening ( 2231 ) tightly.

5. The atomizer of claim 2 , wherein a blocker ( 2322 ) is arranged at an inner end of the liquid injection tube ( 232 ) to block the liquid reservoir (A) from the first liquid inlet ( 2321 ).

6. The atomizer of claim 2 , wherein an inner end of the liquid injection tube ( 232 ) is enclosed.

7. The atomizer of claim 2 , wherein a sealing ring ( 234 ) is arranged between an outer wall of an inner end of the liquid injection tube ( 232 ) and the liquid injection opening ( 2231 ).

8. The atomizer of claim 2 , wherein the liquid injection device ( 23 ) further comprises a second restoring member ( 233 ) providing a force for the liquid injection tube ( 232 ) to move outwards to its original position.

9. The atomizer of claim 8 , wherein the second restoring member ( 233 ) is sleeved outside the liquid injection tube ( 232 ).

10. An electronic cigarette, comprising a cartridge ( 21 ) and a liquid injection device ( 23 ); wherein,
a liquid reservoir (A) is defined in the cartridge ( 21 ), and one end of the cartridge ( 21 ) comprises an end wall ( 223 ) which defines at least one liquid injection opening ( 2231 );
the liquid injection device ( 23 ) is arranged on the end of the cartridge ( 21 ) corresponding to the end wall ( 223 ), the liquid injection device ( 23 ) defines at least one liquid injection channel extending in the at least one liquid injection opening ( 2231 ), and a first liquid inlet ( 2321 ) is defined in the liquid injection channel; and

when the liquid injection device ( 23 ) is pressed inwards, the liquid injection channel moves inwards to communicate the first liquid inlet ( 2321 ) with the liquid reservoir (A); when the liquid injection device ( 23 ) is released, the liquid injection channel restores to its original position to block the first liquid inlet ( 2321 ) from the liquid reservoir (A).

11. The electronic cigarette of claim 10 , wherein the liquid injection device ( 23 ) comprises a liquid injection tube ( 232 ) extending in the liquid injection opening ( 2231 ), and the liquid injection tube ( 232 ) defines the liquid injection channel.

12. The electronic cigarette of claim 11 , wherein the first liquid inlet ( 2321 ) is defined in a side wall of the liquid injection tube ( 232 ).

13. The electronic cigarette of claim 11 , wherein an outer wall of the liquid injection tube ( 232 ) engages with the liquid injection opening ( 2231 ) tightly.

14. The electronic cigarette of claim 11 , wherein a blocker ( 2322 ) is arranged at an inner end of the liquid injection tube ( 232 ) to block the liquid reservoir (A) from the first liquid inlet ( 2321 ).

15. The electronic cigarette of claim 11 , wherein an inner end of the liquid injection tube ( 232 ) is enclosed.

16. The electronic cigarette of claim 11 , wherein a sealing ring ( 234 ) is arranged between an outer wall of an inner end of the liquid injection tube ( 232 ) and the liquid injection opening ( 2231 ).

17. The electronic cigarette of claim 11 , wherein the liquid injection device ( 23 ) further comprises a second restoring member ( 233 ) providing a force for the liquid injection tube ( 232 ) to move outwards to its original position.

18. The electronic cigarette of claim 17 , wherein the second restoring member ( 233 ) is sleeved outside the liquid injection tube ( 232 ).
