   a mouthpiece component, the vaporization cartridge being mounted in the mouthpiece component so as to enable aerosols generated by the vaporization cartridge to flow out through the mouthpiece component; and   a connector separately fitted to the connection portion and the mouthpiece component so as to enable the vaporization cartridge to be mounted in the mouthpiece component.   
     
     
         2 . The vaporizer of  claim 1 , wherein the cartridge tube comprises:
 a housing comprising a first end and a second end opposite each other; and   a plugging member disposed at the first end of the housing, the first end of the vaporization assembly passing through the plugging member, and the plugging member, the inner wall of the cartridge tube, and the outer wall of the vaporization assembly together forming the liquid storage cavity.   
     
     
         3 . The vaporizer of  claim 2 , wherein the vaporization assembly comprises:
 a vent tube, a first end of the vent tube passing through the plugging member, a second end of the vent tube extending out of the housing through the second end of the housing, the connection portion being formed at the second end of the vent tube and located outside the housing; and   a heating component mounted in the vent tube, the heating component being configured to heat a vaporization medium in contact with the heating component in the liquid storage cavity to form aerosols.   
     
     
         4 . The vaporizer of  claim 3 , wherein the vent tube comprises a first tube section and a second tube section connected to each other,
 wherein the first tube section passes through the plugging member,   wherein a part of the structure of the second tube section extends out of the housing through the second end of the housing,   wherein a through hole communicated with the liquid storage cavity is provided in a side wall of the second tube section located in the liquid storage cavity,   wherein the heating component is mounted in the second tube section and corresponds to the through hole, and   wherein the connection portion is formed on the part of the second tube section extending out of the housing.   
     
     
         5 . The vaporizer of  claim 4 , wherein the heating component comprises an absorption member and a heating element, the absorption member being sleeved on the heating element and located between an outer wall of the heating element and an inner wall of the second tube section, and
 wherein the heating element is accommodated in the second tube section, and   wherein the heating element is configured to heat the vaporization medium in the absorption member to generate aerosols.   
     
     
         6 . The vaporizer of  claim 5 , wherein the heating element comprises two electrodes spaced apart from each other, and the connection portion comprises a first conductive member, and
 wherein the vaporization cartridge further comprises:
 a second conductive member, disposed in the connection portion and electrically insulated from the first conductive member, one of the two electrodes being electrically connected to the first conductive member, and an other of the two electrodes being electrically connected to the second conductive member. 
   
     
     
         7 . The vaporizer of  claim 6 , wherein the vaporization cartridge further comprises:
 a first insulator sleeved on the second conductive member and located between the first conductive member and the second conductive member, and   wherein the first insulator electrically insulates the first conductive member from the second conductive member.   
     
     
         8 . The vaporizer of  claim 1 , wherein the mouthpiece component comprises a first end and a second end opposite each other,
 wherein the mouthpiece component is provided with an air passage and an accommodating cavity connected to and communicating with each other, the air passage running through the first end of the mouthpiece component to communicate with the outside, the accommodating cavity running through the second end of the mouthpiece component, and at least part of the vaporization cartridge extending into the air passage.   
     
     
         9 . The vaporizer of  claim 8 , further comprising:
 a third conductive member disposed in the connector, the second conductive member of the vaporization cartridge being electrically connected to the third conductive member; and   a second insulator sleeved on the third conductive member and located between the third conductive member and an inner wall of the connector so as to insulate the third conductive member from the connector.   
     
     
         10 . An aerosol generation device, comprising:
 the vaporizer of  claim 1 .
