Figures 1-4 To enhance the fixing effect of the locking member 4 and more securely lock the filter element 5, one end of the locking member 4 is hinged to the housing 1. A locking hole 6 is provided on the wall of the filter element cavity 3 near the opening. The end of the locking member 4 away from the hinge is provided with a first slot 8 and a telescopic locking head 7 adapted to the locking hole 6. The telescopic locking head 7 is embedded in the first slot 8 and extends out of the first slot 8. When the locking hole 6 is closed, the telescopic locking head 7 is compressed by the wall of the filter element cavity 3 and retracts into the first slot 8. When the telescopic locking head 7 is aligned with the locking hole 6, it extends out into the locking hole 6 to fix the protective cover. The telescopic locking head 7 allows for... The filter element 5 is flexibly and securely fixed. When replacing the filter element 5, press the telescopic locking head 7 to disengage it from the locking hole 6 and retract it back into the first slot 8. Gently snap and flip the locking part 4 to fully open it. At this point, the filter element 5 can be removed and a new filter element 5 can be added. After the filter element 5 is placed in, press the locking part 4 directly so that the telescopic locking head 7 abuts against the filter element cavity 3. The telescopic locking head 7 retracts back into the first slot 8. After the first slot 8 is aligned with the locking hole 6, the telescopic locking head 7 extends into the locking hole 6 and engages with each other to fix the filter element 5, further increasing the stability of fixing the filter element 5.
