AI Technical Summary

Technical Problem

The filter box of the existing water supply device for injection lacks a rigid connection, making it prone to rotation and sliding inside the connecting pipe, which leads to wear and damage, affecting the filtration effect and the life of the device.

Method used

The system employs a locking assembly, including a hinged base and a locking plate, to secure the cover to the filter cylinder via bolts. This ensures the stability of the filter cylinder within the connecting tube. It also incorporates multi-stage filtration using silver ion balls and nano-filter materials, sterilization by an ultraviolet disinfection lamp, and a drive motor to rotate the connecting tube to enhance the filtration effect.

Benefits of technology

It achieves stable fixation of the filter cartridge, extends the service life of the device, improves water purity, ensures the sterility requirements of water for injection, and simplifies the maintenance and replacement process.

Abstract

This utility model belongs to the technical field of pharmaceutical manufacturing equipment, specifically disclosing a water supply device for injection, including a tank body. A connecting pipe is inserted inside the tank body, and a filter screen is installed inside the connecting pipe. A fixed cover is installed above the connecting pipe. A sleeve is fixed on the top of the tank body and fitted onto the connecting pipe. A locking component is provided on the outside of the connecting pipe near the fixed cover. A connecting rod is fixed below the fixed cover, and the end of the connecting rod is fixed to the filter screen. Several slots are opened on the side of the fixed cover, and locking screw holes are opened inside the slots. The locking component includes a hinge seat and a locking plate rotatably connected to the inside of the hinge seat. The hinge seat is fixed to the connecting pipe, and the locking plate cooperates with the slots. A through positioning hole is opened on the locking plate. The positioning hole is aligned with the locking screw hole and fixed by bolts. The fixed cover is fixed by bolts passing through the positioning hole and threaded into the locking screw hole to achieve a fixed connection and facilitate subsequent disassembly and assembly.
