The filter bottle is designed with a snap-fit ​​end, and the end plate of the snap-fit ​​end has an assembly opening. The edge of the water sealing disc assembly is machined with an annular groove. When the water sealing disc assembly is correctly installed into the snap-fit ​​end, the annular groove will align with the assembly opening to ensure the smooth installation of the subsequent fixing component. The fasteners include locking pins. After the fasteners are assembled to the assembly port, the locking pins will be precisely inserted into the annular slot, thereby achieving reliable fixation of the water sealing pan assembly. It has the advantages of reliable structure and simple operation. According to some embodiments of this utility model, the outer wall of the snap-fit ​​end adopts a symmetrical structure and is provided with two sliders. The sliders are used for the fixed connection between the filter element and the water purifier. The two sliders divide the end plate of the snap-fit ​​end into two independent parts, namely the first end plate and the second end plate, and each end plate is provided with an assembly port.

[0004] According to some embodiments of this utility model, two fasteners are also provided, and the two fasteners are respectively installed in two assembly ports, thereby enhancing the stability and sealing of the fastener.

[0005] According to some embodiments of the present invention, each fastener further includes an annular plate, the inner annular surface of which extends horizontally to form a locking pin.

[0006] According to some embodiments of this utility model, a water passage is opened at the bottom of the inner cavity of the snap-fit ​​end, and a second sealing ring is installed around the water passage. To ensure the sealing performance, the second sealing ring needs to be pressed tightly by the water sealing plate assembly. In the installed state of the fastener, the annular plate is located inside the assembly port, and the snap pin extends further into the annular slot, so that the installation position of the water sealing plate assembly is fixed, and the snap pin can keep the water sealing plate assembly downward, so that the water sealing plate assembly maintains a certain amount of compression on the second sealing ring, ensuring good water passage sealing.

[0007] According to some embodiments of this utility model, the locking pin is designed with a segmented structure, meaning it consists of multiple independent small pin blocks arranged at intervals to provide elasticity and adaptability. Correspondingly, multiple spacers are provided inside the assembly port, forming multiple small notches between them. During installation, the small pin blocks can pass through these small notches one by one and finally insert into the annular groove to achieve multi-point fixing, ensuring positioning accuracy and improving the structure's tolerance.

[0008] According to some embodiments of this utility model, the edge of the water sealing tray assembly is further provided with an annular mounting groove, which is located below the annular retaining groove. A sealing ring is installed in the annular mounting groove. After assembly, the sealing ring forms a tight contact with the inner wall of the retaining end, playing a crucial sealing role, effectively preventing liquid leakage, and ensuring that the sealing performance of the filter element in the working state meets the design requirements.

[0009] A second aspect of this utility model provides a filter element including the above-described filter element water sealing structure.

[0010] This utility model has at least the following beneficial effects: 1. After the fastener is assembled to the assembly port, the locking pin will be precisely inserted into the annular slot, thereby achieving reliable fixation of the water sealing pan assembly. It has the advantages of reliable structure and simple operation. 2. The two ends of the ring plate are also provided with hook structures, and the inner side wall of the snap-fit ​​end is machined with corresponding hook openings. When the fastener is installed in place, the hook will be firmly hooked into the hook opening, further enhancing the connection strength and preventing the fastener from loosening or falling off during use.
