     When adjusting the flow of the cigarette liquid, the electronic cigarette atomizer drives the first sleeve  22  to rotate together by rotating the adjustment ring  21 , so that the second liquid inlet  221  on the first sleeve  22  is relatively communicated with or staggered from the third liquid inlet  231  on the second sleeve  23  so as to adjust the flow of the cigarette liquid contained between the first sleeve  22  and the liquid storage tube  1  flowing into the second sleeve  23 , and the cigarette liquid flowing into the second sleeve  23  can directly flow into the atomization head  5 . Referring to  FIG. 12  and  FIG. 13 , by rotating the adjustment ring  21 , when the adjustment ring  21  is rotated clockwise, the second liquid inlet  221  on the inner first sleeve  22  is gradually communicated with the third liquid inlet  231 , the clamping piece  225  is blocked by the connecting arm  4182  between the liquid injection holes  413  when the adjustment ring  21  cannot be rotated, the second liquid inlet  221  is completely aligned with the third liquid inlet  231  on the second sleeve  23 , and the maximum flow of cigarette liquid is reached.

Therefore, the flow of liquid is adjusted by rotating the adjustment ring  21 . Further referring to  FIG. 16 , when the adjustment ring  21  is further rotated anticlockwise, the adjustment ring  21  rotates relative to the first sleeve  22 , the second liquid inlet  221  is still completely staggered with respect to the third liquid inlet  231  on the second sleeve  23 , after a certain rotating distance, and the adjustment ring  21  can be unscrewed relative to the first sleeve  22  and taken down to expose the liquid injection hole  413 . At this time, the cigarette liquid can be directly injected into an annular space between the first liquid storage tube  1  and the first sleeve  22  through the liquid injection hole  413 . 
     Understandably, the screwing connections can all be replaced by other detachable connecting methods, such as a snapping connection, a plugging connection, and a magnetic connection. 
     It can be understood that, in other embodiments, when the adjustment ring  21  is rotated clockwise, the second liquid inlet  221  is gradually staggered with respect to the third liquid inlet  231 , and the liquid flow is getting smaller and smaller. When rotating the adjustment ring  21  counterclockwise, the second liquid inlet  221  in the inner first sleeve  22  is in a state of gradually communicated with the third liquid inlet  231  relatively. 
     Further, a second silicone pad  62  may be set between the annular groove of the base  31  and the liquid storage tube  1  for improving the seal tightness of the cigarette liquid. 
     Further, referring to  FIG. 17 , in order to improve the seal tightness of the cigarette liquid, at least one groove  4152  may be set on the outer periphery of the tube body  415  for placing the sealing ring. 
     Referring  FIG. 18 , the electronic cigarette with the atomizer of the embodiment comprises a cigarette holder  101  and a battery assembly  102  installed on two ends of the electronic cigarette atomizer. The cigarette holder  101  is connected to the top end of the adjustment ring  21 , and the battery assembly  102  is connected to the bottom end of the air adjustment inner ring  32 . The battery is installed in the battery assembly  102  to supply power to the atomization head  5  during smoking, and the user smokes through the cigarette holder  101 . 
     In conclusion, the electronic cigarette atomizer with a liquid adjusting function and the electronic cigarette using the same, according to the second embodiment of the present disclosure, drive the first sleeve  22  to rotate relative to the second sleeve  23  by rotating the adjustment ring  21 , and by aligning or staggering the second liquid inlet  221  on the first sleeve  22  with the third liquid inlet  231  on the second sleeve  23  to open or close the third liquid inlet  231  on the second sleeve  23 . In this way, the adjusting function of cigarette liquid flow can be conveniently realized. Compared with the conventional electronic cigarette atomizer, it is unnecessary to directly immerse the atomization head  5  in the cigarette liquid, and the atomization head  5  and cigarette liquid can be separated or conducted through cooperation of the first sleeve  22  and the second sleeve  23 , so that the user can easily control the cigarette liquid and do not need to disassemble the atomizer. In addition, when the two liquid inlets are conductively communicated with each other, the adjustment ring  21  cannot be taken down to carry out injection; and only when the two liquid inlets are completely staggered, the clamping piece  225  is blocked by the connecting arm  4182 , and the adjustment ring  21  can be removed by further rotating it, which can effectively prevent liquid leakage.
