Therefore, raw water enters the raw water cavity 1011 to have rectification and flow guide effects, so that water flow is more stable, and the aeration phenomenon is reduced.

With reference to fig. 1 and 10, in some embodiments of the present invention, the filtering device 1 further includes a cover 700, the cover 700 covers the casing 100, and the cover 700 is provided with a plurality of inlet holes 701 and a plurality of outlet holes 702 communicated with the water containing cavity 101. Raw water can be rectified through the water inlet hole 701 and the air outlet hole 702, and gas-water separation is effectively realized, so that the water purifying cavity 1012 is in negative pressure when full flow occurs. The raw water enters the raw water cavity to have the functions of rectification and diversion, so that the water flow is more stable, the aeration phenomenon is reduced, the phenomenon that the flow speed is suddenly reduced due to the fact that more air is mixed in the raw water and enters the filter material is avoided, and the filtering efficiency is further improved.

Optionally, a plurality of water inlet holes 701 are located on the peripheral wall of the cover body 700 and arranged in an array, and a plurality of air outlet holes 702 are located at the top of the cover body 700. Thereby making the cover body 700 have the functions of rectification and diversion, making the water flow stable, and realizing the gas-water separation to a certain extent.

Optionally, the cover 700 is connected to the housing 100 by a snap fit, so that the cover 700 can be covered on the housing 100.

According to the utility model discloses the filtration equipment of second aspect through foretell filter equipment 1's setting for the filter media's filter speed promotes, improves the velocity of water, guarantees that the rivers flow stably, goes out the water stability.
