FILTER
First Claim
1. A filter comprising:
- a filter core, wherein the filter core has a portion through which a fluid to be filtered passes;
a top cover and a bottom cover, in which the top cover and the bottom cover are respectively fixed to an upper portion and a lower portion of the filter core;
an inner wall surface of the filter core, an inner wall surface of the top cover and an inner wall surface of the bottom cover define a filter cavity;
a first discharging pipe, in which the first discharging pipe communicates with the filter cavity and is provided at the top cover and has a first inlet through which the fluid flows;
a second discharging pipe, in which the second discharging pipe communicates with the filter cavity and has a second inlet through which the fluid flows; and
the first inlet is situated above the second inlet in the gravity direction.

Abstract
Disclosed is an improved filter having a filter core, a top cover, a bottom cover, at least one first discharging pipe and at least one second discharging pipe, wherein the filter core has a slot through which a fluid to be filtered passes; the top cover and the bottom cover are respectively fixed to an upper portion and a lower portion of the filter core; an inner wall surface of the filter core, an inner wall surface of the top cover and an inner wall surface of the bottom cover define a filter cavity; the first discharging pipe, which communicates with the filter cavity and is provided at the top cover, has at least one first inlet through which the fluid flows in; the second discharging pipe, which communicates with the filter cavity and is provided at the top cover or the bottom cover, has at least one second inlet through which the fluid flows in; and all the first inlets are situated above the second inlets in the gravity direction. The filter can not only ensure the filtration precision, but also realize the separation of two fluids.
