The blocking portion 22 is movable relative to the pipe 10 in a first direction B to open or close the communication relationship of the pipe 10 relative to the filtering portion 23; the initial moving direction of the locking portion from the locked state to the unlocked state is different from the first direction B.

After the filter part 23 is mounted on the blocking part 22, the filter part 23 is limited not to displace relative to the blocking part 22 by adjusting the locking part to be in a locking state; when the filter portion 23 needs to be detached, the lock portion needs to be adjusted to enter the unlock state. Since the initial moving direction of the locking portion from the locked state to the unlocked state is opposite to the detaching direction of the filtering portion 23 relative to the blocking portion 22, in order to detach the filtering portion 23 from the blocking portion 22, the locking portion needs to be moved to the unlocked state, and then the filtering portion 23 is moved in the direction opposite to the initial moving direction, so that the limiting effect of the locking portion on the filtering portion 23 is well ensured. Since the initial moving direction of the locking portion from the locked state to the unlocked state is different from the first direction B, it is possible to avoid that the locking portion enters the unlocked state due to a malfunction when the blocking portion 22 is adjusted to close the communicating relationship, and further, the limiting action of the locking portion on the filter portion 23 is lost.
