Filtering device

A filtering device for purifying a fluid having a first flow rate, the filtering device comprising:

• a housing comprising a body, an inlet end and an outlet end, the body forming an accommodating space, the inlet end and the outlet end being respectively formed at two ends of the accommodating space, and the inlet end receiving fluid;
• a blocking member disposed in the accommodating space, the blocking member dividing the accommodating space into a first subspace and a second subspace, the blocking member splitting the fluid into a plurality of secondary fluids and collecting a non-fluid composition which is a part of the secondary fluid and has a first size, the blocking member further establishing a channel between the first subspace and the second subspace;
• an accelerating component connected in series to the inlet end, the accelerating component being used to adjust the fluid from the first flow rate to a second flow rate, wherein the fluid passes through the accelerating component to the blocking member;
• and
• a screening member disposed between the inlet end and the blocking member and on an outer periphery of the accelerating component, the screening member being configured to receive the Plurality of secondary fluids reflected from the blocking member to limit another non-fluid composition which is another part of the secondary fluids and has a second size to the screening, member;
• wherein, after the secondary fluids pass through the blocking member and be reflected from the blocking member to pass through the screening member, the secondary fluids enter from the first subspace into the second subspace through the channel, and are outputted from the outlet end connected to the second subspace.
