[0022] like Figure 1As shown, in one embodiment of this utility model, the shell structure of the water purifier includes a cover 100, an outer shell 200, and a bracket 300. The outer shell 200 has an installation cavity 201, and a fastening member 210 is provided on the side of the outer shell 200 facing the cover 100. The cover 100 is detachably connected to the fastening member 210, and a locking member 110 is provided on the side of the cover 100 facing the outer shell 200. The bracket 300 is used to (lock in) the filter element of the water purifier, and the bracket 300 is connected to the interior of the installation cavity 201. A mating member 310 is provided on the side of the bracket 300 facing the cover 100. The locking member 110 is detachably connected to the mating member 310. Wherein, as... Figure 7 As shown, the bracket 300 is provided with at least one mounting channel 303; the mounting channel 303 is used for (clamping) mounting the filter element of the water purifier. The outer shell 200 is either a U-shaped structure or an irregular structure with an opening at the top and one side (with a bottom seal).

[0023] The technical solution of this utility model adopts a detachable connection between the cover and the outer shell, combined with a detachable connection between the upper cover and the bracket, to ensure assembly stability while improving the convenience of disassembly and installation. This reduces the need for tools such as screws and screwdrivers to assist in disassembly and assembly, thereby improving the efficiency and convenience of disassembly and assembly of the shell structure, and also facilitating the maintenance and replacement of accessories such as filter elements and shell structures.

[0024] Specifically, in some implementations, such as Figure 1 and 2 As shown, the cover 100 includes a cover 120 and an edge 130 connected to the bottom surface of the cover 120; a locking member 110 is connected to the bottom surface of the cover 120; and the edge 130 is detachably connected to the fastening member 210. Wherein, as... Figure 2 As shown, the edge 130 is arranged around the bottom surface of the cover 120 in the circumferential direction. That is, the edge 130 has a U-shaped structure and is fastened to the upper surface of the outer shell 200; thereby improving the compactness and sealing of the assembly.

[0025] Specifically, in some implementations, such as Figure 2 and 4 As shown in Figures 5 and 6, a limiting protrusion 150 is provided on the inner surface of edge 130; the fastening member 210 includes a fastening side plate 211 and a fastening folding plate 212; the bottom of the fastening side plate 211 is connected to the top surface of the housing 200; the fastening folding plate 212 is connected to the outer surface of the fastening side plate 211 away from the mounting cavity 201, and a fastening groove 215 is provided between the fastening folding plate 212, the fastening side plate 211 and the housing 200; the limiting protrusion 150 is engaged with the inner wall of the fastening groove 215.

That is, the third horizontal section 213 and the third vertical section 214 form an L-shaped fastening folding plate 212. During assembly, the limiting protrusion 150 is placed between the two fastening folding plates 212 from top to bottom, and then the limiting protrusion 150 is pushed forward so that the limiting protrusion 150 is engaged with the fastening groove 215; this achieves a limiting action by abutting the inner side of the fastening side plate 211, thereby preventing it from collapsing inward or falling off to the left or right; and combined with the limiting action of the upper L-shaped fastening folding plate 212 on the limiting protrusion 150 in the vertical direction, this prevents it from jumping up and down and falling off. Further, as Figure 2 and 3 As shown, the limiting protrusion 150 includes at least one limiting protrusion 151; the inner surface of the limiting protrusion 151 is provided with an arc-shaped limiting groove 152; the outer surface of the fastening side plate 211 facing the fastening groove 215 is provided with an arc-shaped limiting post; the limiting post is engaged with the limiting groove 152.

In some embodiments, such as... Figure 1 , 2 As shown in Figure 4, the first abutting arc surface 101 includes an abutting straight section 131 and an abutting arc section 132 connected sequentially along the length direction; the second abutting arc surface 202 includes a mating arc section 203 and a mating straight section 204 connected sequentially along the length direction; and the mating arc section 203 abuts against the abutting arc section 132; the mating straight section 204 abuts against the abutting straight section 131. This structure abuts against the arc-shaped stepped second abutting arc surface 202 and assembles it to the arc-shaped stepped first abutting arc surface 101, so as to prevent the cover 100 from sliding forward and falling off the outer shell 200; and to ensure the stability of the assembly; and can also reduce the steps of disassembly and assembly by using tools such as screws and screwdrivers.

[0029] Specifically, in some implementations, such as Figure 2 and 4 As shown, the outer casing 200 has at least one positioning post 205 on the inner wall facing the mounting cavity 201; the inner surface of the cover 100 (middle edge 130) has at least one positioning part 160; the positioning part 160 is detachably connected to the positioning post 205.

In some embodiments, such as... Figure 2 , 3As shown in Figure 7, the mating component 310 includes a second horizontal section 312 and a second vertical section 311 that are inclined to each other; the second vertical section 311 is connected to the bracket 300; and a first slot 313 is provided between the second horizontal section 312, the second vertical section 311, and the bracket 300; in the locking component 110, the first horizontal section 111 is engaged with the first slot 313; and the second horizontal section 312 is engaged with the second slot. That is, by using the L-shaped locking component 110 to engage with the first slot 313, and combining the L-shaped mating component 310 with the second slot, a bidirectional interlocking assembly can be achieved, thereby reducing the need for tools such as screws and screwdrivers to assist in disassembly and assembly; and ensuring the stability of the assembly.
