A pair of opposite sockets  621  are defined in the upper surface of the first electrode  62  adjacent to one end of the heating member  71 . The two heating members  71  are relatively closely inserted into the sockets  621 . Specifically, the groove bottom of the socket  621  is flush with or lower than the upper surface of the mounting seat  61 . When the heating member  71  is inserted in the socket  621 , as shown in  FIG. 14 , the lower end of the heating member  71  located on opposite sides of the socket  621  abuts against the upper surface of the mounting seat  61 , the liquid absorbing member  72  is directly inserted into the mounting groove  714  formed between the two heating members  71 .

For another example, when the heating members  71  are spaced along a straight line, the number of the mounting grooves  714  is one less than the total number of the heating members  71 . 
     When the heating member  71  and the liquid absorbing member  72  need to be replaced, the housing  40  is removed, the heating member  71  and the liquid absorbing member  72  are exposed to the outside, the old liquid absorbing member  72  is directly taken out from the mounting groove  714 , and directly pulling out the heating member  71  from the socket  621  of the first electrode  62 . When installing, a new heating member  71  is inserted into the socket  621 , a new liquid absorbing member  72  is inserted into the mounting groove  714 , and finally the housing  40  is sleeved on the mounting seat  61 .
