[0030] The utility model discloses a water purification device, such as Figures 1 to 4As shown, the water purification device includes a main body frame 100 and a waterway plate 200, and the main body frame 100 and the waterway plate 200 need to be assembled in a first direction. Figure 1 As shown in (a) in the figure, to facilitate assembly of the main body midframe 100 and the waterway plate 200, the main body midframe 100 comprises a first assembly surface 101, a protruding connection portion 102, and a first connection portion 103. The protruding connection portion 102 protrudes from the first assembly surface 101 in a first direction, and the first connection portion 103 is flush with the first assembly surface 101 in the first direction. That is, in the first direction, part of the protruding connection portion 102 is located within the main structure of the main body midframe 100, while the remaining part protrudes from the first assembly surface 101 and is located outside the main structure of the main body midframe 100. The portion of the protruding connection portion 102 that protrudes outside the first assembly surface 101 is defined as the protruding portion; the first connection portion 103 is entirely located within the main structure of the main body midframe 100. The waterway plate 200 has a second assembly surface 201, a recessed connection portion 202 and a second connection portion 203. The recessed connection portion 202 is recessed inwardly of the second assembly surface 201 in the first direction, and the second connection portion 203 is flush with the second assembly surface 201 in the first direction.
