The plurality of purification units 200 comprises a first purification unit 200a matched with the first pull-out cavity 111 and a second purification unit 200b matched with the second pull-out cavity 112.

[0102] As shown in the drawings, Figure 16 and Figure 19 the longitudinal center line 221c of the first positioning part 221 is offset towards the direction close to the second pull-out cavity 112 relative to the longitudinal center line 131c of the first guide part 131, and correspondingly, the positioning matching part 41 on the first purification unit 200a is offset towards the direction close to the second pull-out cavity 112 relative to the center of the first guide part 131, so as to be inserted and matched with the first positioning part 221.

For example, when the upstream and downstream relationship of the first purification unit 200a and the second purification unit 200b needs to be guaranteed, the reverse assembly of the first purification unit 200a and the second purification unit 200b will cause the purification effect of the purification component 1000 to be reduced or even invalid, affecting the normal work of the purification module; or, for another example, when the first purification unit 200a can only be electrically connected with the first electrical contact portion 21a, and cannot be electrically connected with the second electrical contact portion 21b, and the second purification unit 200b can only be electrically connected with the second electrical contact portion 21b, and cannot be electrically connected with the first electrical contact portion 21a, the reverse assembly of the first purification unit 200a and the second purification unit 200b will cause the purification component 1000 to be unable to work normally.
