In a preferred embodiment, the first direction, the second direction and the third direction are perpendicular to each other.

Further, the lower base bottom wall 112 has two electrode mounting holes 1121 and at least one lower base air inlet hole 1123 formed therethrough. The two electrode mounting holes 1121 are disposed at an interval in the second direction, and each electrode mounting hole 1121 communicates with the lower base mounting cavity 116 and the external environment, so that the electrode 50 can extend into the lower base mounting cavity 116 through the electrode mounting hole 1121. At least one lower base air intake hole 1123 is located between the two electrode mounting holes 1121, and each lower base air intake hole 1123 communicates the lower base mounting cavity 116 with the external environment.
