AI Technical Summary
Existing water treatment devices have a large flow path area when replacing filter cartridges, making them susceptible to contamination by external foreign objects. Furthermore, the filter cartridges are prone to falling off, leading to problems such as water leakage and reduced flow.
A water treatment device was designed that enables the rotational installation and separation of filter cartridges through a flow path conversion component, thereby reducing the exposed area of the flow path, lowering the risk of leakage, and optimizing the flow path structure to reduce resistance.
It simplifies the installation and separation process of filter elements, reduces the risk of leakage, increases the treatment flow rate, reduces scale buildup and foreign matter contamination, and maintains a stable connection between the filter head and filter cap.
