Please refer to FIG. 2 again. The metal net filter 12 in the storage space 110 of the storage board 11 is connected to the input end 21 of one negative ion generator 20,
The output terminal 22 of the negative ion generator 20 is one discharge terminal. The working voltage of the negative ion generator 20 is slightly increased by an electrostatic high voltage generator (not shown in the figure) composed of an appropriate number of diodes and capacitors, and the discharge end (output) Supply sufficient working voltage to generate negative ions at the end 22). The principle of operation of this electrostatic high-voltage generator is a well-known technique, and a detailed description is omitted here.

On the accommodation board 11, another accommodation board 14 having the same shape and dimensions as the accommodation board 11 is combined, and the positioning between the two accommodation boards 11, 14 is determined by the lower accommodation board. This is performed by using the fitting of the concave hole 113 on the upper end face of the board 11 and the projection 144 on the lower end of the accommodation board 14 above.
