The top cover includes a mouthpiece and a liquid injection member mounted on one end of the mouthpiece. The atomizing assembly includes a first pressing ring and a fixing member fixed on one end of the first pressing ring. The fixing member is sleeved on the liquid injection member, and the liquid injection member is able to move along an axial direction of the atomizer, to cause the liquid injection member separating apart from the first pressing ring for adding cigarette liquid. An aerosol generating apparatus with the atomizer is also provided. ## Claims ### Claim 1 An atomizer comprising a top cover, a bottom seat, and an atomizing assembly mounted between the top cover and the bottom seat, wherein the top cover comprises a mouthpiece and a liquid injection member mounted on one end of the mouthpiece, the atomizing assembly comprises a first pressing ring and a fixing member fixed on one end of the first pressing ring, the fixing member is sleeved on the liquid injection member, and the liquid injection member is able to move along an axial direction of the atomizer, to cause the liquid injection member separating apart from the first pressing ring for adding cigarette liquid, the atomizing assembly comprises an elastic member, the elastic member is sleeved on the liquid injection member, when the liquid injection member moves downwardly along the axial direction of the atomizer to compress the elastic member, the liquid injection member is separated apart from the first pressing ring for adding cigarette liquid, when the elastic member restores, the liquid injection member comes back to its original position and is sealed with the first pressing ring. ### Claim 2 (depends on 1) The atomizer of claim 1, wherein the liquid injection member comprises a first connecting part and a second connecting part connected with the first connecting part, the mouthpiece is detachably mounted to one end of the first connecting part that is far away from the second connecting part. ### Claim 3 (depends on 2) The atomizer of claim 2, wherein the top cover further comprises a first sealing element, the second connecting part has a swallow-tailed cross section, one end of the second connecting part with smaller diameter is connected with the first connecting part, an outer surface of the second connecting part is provided with a receiving groove, the first sealing element is disposed in the receiving groove for sealing the first pressing ring and the liquid injection member. ### Claim 4 (depends on 2) The atomizer of claim 2, wherein one end of the second connecting part that is far away from the first connecting part is provided with a sleeve extending along an axial direction of the liquid injection member, the elastic member is sleeved on the sleeve, one end of the fixing member is provided with an abutting portion extending radially inwardly towards the center of the fixing member, one end of the elastic member abuts against the liquid injection member, the other end of the elastic member abuts against the abutting portion. ### Claim 5 (depends on 4) The atomizer of claim 4, wherein one end of the second connecting part that is far away from the first connecting part is provided with a stopping part extending along the axial direction of the liquid injection member, the sleeve and the stopping part are coaxially arranged with the stopping part being disposed at an outer side of the sleeve, a receiving portion is formed between the sleeve and the stopping part, one end of the elastic member abuts against the receiving portion. ### Claim 6 An atomizer comprising a top cover, a bottom seat, and an atomizing assembly mounted between the top cover and the bottom seat, wherein the top cover comprises a mouthpiece and a liquid injection member mounted on one end of the mouthpiece, the atomizing assembly comprises a first pressing ring and a fixing member fixed on one end of the first pressing ring, the fixing member is sleeved on the liquid injection member, and the liquid injection member is able to move along an axial direction of the atomizer, to cause the liquid injection member separating apart from the first pressing ring for adding cigarette liquid, the liquid injection member is provided with an outer thread, the fixing member is provided with an inner thread corresponding to the outer thread, when the liquid injection member is rotated downwardly along the axial direction of the atomizer, the liquid injection member is separated apart from the first pressing ring for adding cigarette liquid, when the liquid injection member is rotated upwardly, the liquid injection member comes back to its original position and is sealed with the first pressing ring. ### Claim 7 (depends on 6) The atomizer of claim 6, wherein the liquid injection member comprises a first connecting part and a second connecting part connected with the first connecting part, the mouthpiece is detachably mounted to one end of the first connecting part that is far away from the second connecting part. ### Claim 8 (depends on 7) The atomizer of claim 7, wherein one end of the second connecting part that is far away from the first connecting part is provided with a sleeve extending along an axial direction of the liquid injection member, the outer thread is formed on the sleeve. ### Claim 9 (depends on 1) An aerosol generating apparatus comprising the atomizer of claim 1. ### Claim 10 (depends on 6) An aerosol generating apparatus comprising the atomizer of claim 6.
