[0034] like Figures 1 to 8 As shown, a water purifier with easy-to-install and remove filter cartridges includes a housing body 1. A pipe connection assembly 2 is disposed inside the housing body 1. The pipe connection assembly 2 connects a first filter cartridge 3 and a second filter cartridge 4. Fixing rods 6 are provided on both sides of the first filter cartridge 3 and the second filter cartridge 4. A locking cover 5 corresponding to the first filter cartridge 3 and the second filter cartridge 4 is rotatably connected to the pipe connection assembly 2. Limiting rods 501 are provided on both sides of the locking cover 5. The filter cartridge installation and removal process is as follows: When installing the first filter cartridge 3 and the second filter cartridge 4, insert the first filter cartridge 3 and the second filter cartridge 4 into the corresponding positions on the pipe connection assembly 2, and rotate the locking cover 5 downwards until the locking cover 5 is in position... Figure 7 The cover shown is connected above the first filter element 3 and the second filter element 4, thereby locking the first filter element 3 and the second filter element 4 onto the pipe connection assembly 2, effectively ensuring a tight connection between the pipe connection assembly 2 and the first filter element 3 and the second filter element 4, preventing water leakage. When disassembling the first filter element 3 and the second filter element 4, rotate the locking cover 5 upwards, causing the limiting rod 501 to... Figure 8 The rod is tilted upwards and pushed forward to move the fixing rod 6, thereby disengaging the first filter element 3 and the second filter element 4 from the pipe connection assembly 2. By changing the rotation state of the locking cover 5, the locking condition of the locking cover 5 on the first filter element 3 and the second filter element 4 can be adjusted so that the first filter element 3 and the second filter element 4 can be quickly disassembled and assembled.
