This kind of structure, after inserted sheet section 1212 and calorie hole 1143 cooperation, the inside contact of the free end of extension section 1213 and the lateral wall of installation cavity 114 through the cooperation of extension section 1213 and inserted sheet section 1212, further increases the fixed effect of purification module 120 installation behind installation cavity 114. Wherein the free end of the extension 1213 faces the card hole 1143.
In this embodiment, an included angle β is formed between the outer sidewall of the extension section 1213 and the outer sidewall of the elastic piece section 1211, and the value range of the included angle β is: beta is more than or equal to 90 degrees and less than or equal to 180 degrees. This arrangement facilitates contact of the free end of the extension 1213 with the interior of the side wall of the mounting cavity 114.
In this embodiment, the height h1 of the blade insertion section 1212 is greater than the protrusion height h2 of the extension section 1213 relative to the outer side wall of the spring section 1211. This configuration facilitates mating of the extension section 1213 and the tab section 1212.
In some embodiments, the buckle 121 includes a connection section 1214, one end of the connection section 1214 is connected to the sidewall of the purification module 120, the other end of the connection section 1214 is connected to the elastic sheet 1211, the connection section 1214 is disposed in an arc shape, and the arc shape of the connection section 1214 faces the outside of the installation cavity 114. This kind of structure is connected purification module 120 and shell fragment section 1211 through setting up linkage segment 1214, because linkage segment 1214 is the arc setting, when purification module 120 installed in installation cavity 114 or when dismantling from installation cavity 114 through calorie hole 1143 and buckle 121, linkage segment 1214 can have certain home range with the junction of the lateral wall of purification module 120 as the center, linkage segment 1214, is convenient for the cooperation of insertion segment 1212 and calorie hole 1143.
