In this way, the electrode 230 is arranged opposite to the first groove 201 and the second groove 202, respectively. By arranging the first groove 201 and the second groove 202, the problem that the electrode 230 hinders the gas flow between the gas mist passage 10012 and the gas guide passage 1002 can be solved.

[0085] In some embodiments, please refer to Figure 1 , Figure 3 and Figure 5 , and in conjunction with other drawings. The gas mist passage 10012 extends through the gas channel member 20 in the third direction Y.

[0086] The mounting cavity 103 extends through the support 10 on the side away from the third inner wall 1033 in the third direction Y, and the solid wall where the third inner wall 1033 is located is provided with the mist outlet passage 107 in the third direction Y.
