Pitcher Water Purifier Casing Segmentation and Lid Dynamics

The casing is divided into two separate parts: the peripheral wall and the bottom. The peripheral wall is injection-molded from transparent resin, while the bottom is separately formed and then attached to the peripheral wall. This segmentation allows each part to be optimized independently - the bottom can be made from high-impact-resistance material or designed with reinforcement structures without affecting the manufacturing simplicity of the peripheral wall.

By dividing the casing into separable components (peripheral wall and bottom), the design team can independently optimize the shape of each part. The peripheral wall can be designed with specific contours for aesthetic or functional purposes, while the bottom can be shaped to accommodate mounting requirements or structural reinforcement, without being constrained by integral molding limitations.

The pitcher lid incorporates a rotatable dial board that can be positioned in different orientations. When mounted vertically, the lid provides liquid-tight closing. When the pitcher is mounted horizontally in a refrigerator, the dial board can be rotated to a horizontal position, allowing the pitcher to be stored transversely while maintaining sealing functionality. This dynamic adjustment capability enables the same lid design to support both vertical and horizontal mounting configurations.

The housing lid with intake holes is positioned at the top of the cartridge, creating a three-dimensional arrangement where water enters from above and flows downward through the purification materials. This vertical flow path maximizes the utilization of the cartridge's internal volume, allowing purification materials to be filled efficiently in the lower portions while maintaining effective water intake and filtration performance in the upper sections with the lid and intake holes.
