The utility model relates to an automatic drainage device of preferred embodiment's automatic drainage principle as follows:

the water level valve 3 is automatically opened along with the accumulation of the stored liquid in the water storage chamber 2;

the filtered liquid flows along the pipe 4 into the reservoir 2 so that the liquid collects in the reservoir 2; as the filtered liquid enters the water storage chamber 2, the water level inside the water storage chamber 2 gradually rises, so that the floating plate 33 inside the water storage chamber 2 is pushed to move upwards; as the floating plate 33 floats up, the floating plate 33 contacts the second transmission rod 322, so that the second transmission rod 322 is acted by an upward force; as the liquid is injected, the floating plate 33 pushes the second transmission rod 322 to move upwards until the second absorption block 52 and the first absorption block 51 contact with each other, so that the second transmission rod 322 can drive the first transmission rod 321 to open the valve 31, thereby realizing the automatic opening of the water level valve 3.

Liquid storage and discharge in the water storage chamber 2:

after the valve 31 is opened, the liquid in the water storage chamber 2 is discharged from the water outlet, so that the water level in the water storage chamber 2 is lowered, and the floating plate 33 is lowered along with the water level; because the attraction force when the first adsorption block 51 contacts the second adsorption block 52 is not less than the sum of the gravity of the valve 31 and the gravity of the transmission mechanism 32, after the floating plate 33 descends, the second transmission rod 322 is still positioned at the top of the water storage chamber 2, the valve 31 is still in an open state, that is, the water storage chamber 2 still discharges water to the outside, and the drainage rate is unchanged; as the liquid in the water storage chamber 2 decreases, the floating plate 33 continues to move downward, and when the floating plate 33 moves to the positioning block 323 or the floating plate 33 moves to stretch the positioning rope 324 into a straight line, the water level continues to drop, and the floating plate 33 stops dropping.

After the liquid in the water storage chamber 2 is discharged, the water level valve 3 is automatically closed.

As the water level in the water storage chamber 2 continues to drop, the buoyancy force applied to the floating plate 33 is smaller than the self gravity of the floating plate 33, so that the floating plate 33 presses or pulls the transmission mechanism 32 downwards through the positioning block 323 and/or the positioning rope 324; since the attraction force when the first adsorption block 51 contacts the second adsorption block 52 is not greater than the sum of the gravity of the valve 31, the transmission mechanism 32 and the floating plate 33, the first adsorption block 51 is separated from the second adsorption block 52 as the water level in the water storage chamber 2 decreases, and the transmission mechanism 32 and the valve 31 move downward, so that the valve 31 is closed, thereby realizing the automatic closing of the water level valve 3.

When the positioning block 323 is positioned near the bottom of the storage chamber 2 and/or the positioning string 324 is stretched linearly, the floating plate 33 approaches the bottom of the storage chamber, and the liquid in the storage chamber 2 can be completely discharged.

Referring to fig. 1, the filter assembly 1 includes a filter housing 11 for filtering foreign substances in a liquid, and a cover body 12 for sealing the filter housing 11.

As a preferred embodiment of the utility model, the side of the filter cover 11 is provided with a filter screen, and the bottom of the filter cover 11 is communicated with the pipeline 4.

As a preferred embodiment of the present invention, the cover 12 is located on top of the filter housing 11 and detachably connected to the filter housing 11, for example, by a screw, a bolt, a snap, etc.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention.
