         9 . The humidifier according to  claim 8 , wherein the liquid tank comprises a tank body and a bottom plate connected at a bottom wall of the tank body, the connecting plate is arranged between the tank body and the bottom plate, a bottom wall of the tank body defines a through hole, the automizer element extends into the tank body through the through hole. 
     
     
         10 . The humidifier according to  claim 9 , wherein a waterproof sealing element arranged inside the through hole surrounds the automizer element and resists against a sidewall of the automizer element. 
     
     
         11 . The humidifier according to  claim 9 , wherein the bottom wall of the tank body is recessed to define a recess facing the connecting plate, when the connecting plate is connected with the tank body, a receiving space is formed between the bottom wall of the tank body and the connecting plate for receiving the connecting plate. 
     
     
         12 . The humidifier according to  claim 8 , wherein the bottom plate defines a through hole, the second electrical connecting element extends through the through hole so as to be capable of being connected with the first electrical connecting element when the liquid tank is connected with the base. 
     
     
         13 . The humidifier according to  claim 12 , wherein the second electrical connecting element is a metal pin. 
     
     
         14 .
