         4 . The atomizer according to  claim 3 , wherein there are at least two limit posts, and the limit posts are provided at intervals along the circumferential direction of the housing. 
     
     
         5 . The atomizer according to  claim 3 , further comprising first sealing members and second sealing members, wherein the first sealing members and the second sealing members are sleeved on the surface of the peripheral side of the first end at intervals, and the first sealing members and the second sealing members are respectively located on two opposite sides of the mounting holes. 
     
     
         6 . The atomizer according to  claim 1 , wherein the surface of the peripheral side of the base close to the first end is in interference fit with the inner wall of the cavity, enabling the base to be fixed within the cavity. 
     
     
         7 . The atomizer according to  claim 1 , wherein the first end is adhesively connected to the inner wall of the cavity, enabling the base to be fixed within the cavity. 
     
     
         8 . The atomizer according to  claim 2 , wherein the suction nozzle assembly comprises a bracket and a sealing cover, the bracket is fixed at the opening, the sealing cover is inserted into the bracket and connected to the second end of the base, the sealing cover is provided with a through hole in communication with the outlet channel, and the aerosol generated by the atomization core assembly heating the aerosol generation substrate can be discharged to the outside via the outlet channel and the through hole. 
     
     
         9 . The atomizer according to  claim 8 , wherein the suction nozzle assembly further comprises third sealing members, wherein the third sealing members are sleeved on the sealing cover, and some of the third sealing members are located between the side wall of the sealing cover and the inner wall of the bracket, while some of the third sealing members are located between the inner wall of the sealing cover and the outer wall of the second end. 
     
     
         10 . The atomizer according to  claim 2 , wherein the end face of the second end is located within the cavity.
