     DETAILED DESCRIPTION 
     The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present disclosure. All other embodiments obtained by those skilled in the art based on the embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure. 
     As shown in  FIG.  1   , the embodiment of the present disclosure provides a faucet outlet screen filter  1 , including a metal mesh  10  having a plurality of layers. The metal mesh  10  is formed by criss-crossingly connecting a plurality of metal wires  103  and includes mesh holes  104 , where the mesh holes are uniform in sizes and the sizes of the mesh holes are less than or equal to 0.6 mm. The metal mesh  10  having the plurality of the layers is constructed by inlaying, and the mesh holes  104  of each of the plurality of the layers of the metal mesh  10  are staggered with each other. Bottom walls  101  of the metal mesh  10  are generally flat surfaces, and have no large protrusion and recession. Side walls  102  of the metal mesh  10  are curved surfaces, and each of the side walls includes an extension edge  1201 , where the extension edge  1201  extends outwards. Open space regions  105  are space regions which are opened and formed by connecting the bottom walls  101  and the side walls  102 . The plurality of the metal wires  103  is steel having consistent material and uniform size. Referring to  FIG.  1    and  FIG.  2   , the metal mesh  10  further includes a first length L 1  and a second length L 2 , and the first length L 1  is less than the second length L 2 . 
     When in use, the faucet outlet screen filter  1  may effectively reduce a flow rate of water flow, so as to slow down the water flow. When the water flow enters the faucet outlet screen filter  1  through the open space regions  105 , the faucet outlet screen filter  1  is formed by inlaying the metal mesh  10  having the plurality of the layers. The metal mesh  10  is formed by criss-crossingly connecting the plurality of metal wires  103 , and since the plurality of the metal wires is made of the steel having the consistent material and the uniform size, which has high strength and high ductility and further ensures that the metal mesh  10  is not damaged under the flow rate of the water flow in a faucet. Further, the metal mesh  10  is integrally formed, so that the strength of the metal mesh  10  is further enhanced, and the metal mesh  10  is further ensured not to be damaged by the water flow. When the water flow enters the metal mesh  10 , since each of the mesh holes  104  of the metal mesh  10  has a size less than or equal to 0.6 mm, the water flow may be effectively distributed, thereby decreasing the flow rate of the water flow. Moreover, the faucet outlet screen filter  1  further provides the metal mesh  10  having the plurality of the layers, and the mesh holes  104  of each of the plurality of the layers of metal mesh  10  are staggered with each other, so as to distribute the water flow in a staggered manner and decrease the flow rate of the water flow. The bottom walls  101  of the metal mesh  10  are generally flat surfaces, so that when the metal mesh  10  filters the water flow, the mesh holes  104  on the bottom walls  101  clearly distribute the water flow, the water flow is divided into a smaller amount, and the flow rate of the water flow is further decreased. The side walls  102  of the metal mash  10  are curved surfaces, and each of the side walls  102  of the metal mesh  10  further includes an extension edge  1021 , such a structure may ensure that the metal mesh  10  may be effectively fixed in the faucet without displacement. The metal mesh  10  further includes the first length L 1  and the second length L 2 , the first length L 1  is a length of each of the bottom walls of the metal mesh  10 , the second length L 2  is a length of an opening of the metal mesh  10 , and the first length L 1  is less than the second length L 2 . 
     The present disclosure further provides a novel faucet. As show in  FIG.  3   , The faucet outlet screen filter  1  is embedded in a faucet  2 , the bottom walls  101  of the metal mesh  10  of the faucet outlet screen filter  1  are parallel to a water outlet  23 . As shown in  FIG.  4   , the bottom walls  101  of the metal mesh  10  completely cover the water outlet  23  of the faucet  2 , and the water flow may not generate additional splash water. As shown in  FIG.  5    and  FIG.  6   , the faucet  2  further includes a mounting portion  21 , a faucet pipe  22 , and the water outlet  23 . The mounting portion  21  is composed of two baffles, the side walls  102  of the metal mesh  10  are in close contact with the mounting portion  21 , the extension edge  1021  of each of the side walls of the metal mesh  10  is located between the two baffles of the mounting portion  21 , so that the faucet outlet screen filter  1  is fixed and may not displace due to excessive flow rate of the water flow. The faucet pipe  22  is a pipe in which a water source is communicated with the faucet  2 . The water outlet  23  is a portion where the faucet  2  discharge the water flow. When in use, the water flow flows into the faucet outlet screen filter  1  from the faucet pipe  22 , since the faucet outlet screen filter  1  is formed by inlaying the plurality of the layers of the metal mesh  10 , the water flow enters the bottom walls  101  of the metal mesh  10  after flowing through the open space regions  105 , and the size of each of the mesh holes  104  on the bottom walls  101  of the metal mesh  10  is smaller than or equal to 0.6 mm, the water flow is distributed by the staggered mesh holes to further decrease the flow rate, thereby slowing down the water flow and flowing out the water flow. Moreover, the faucet outlet screen filter  1  provides the metal mesh  10  having the plurality of the layers, and the mesh holes  104  on the bottom walls of the metal mesh  10  are staggered with each other, so as to distribute the water flow in a staggered manner and buffer the water flow in a multi-layered manner, the flow rate of the water flow is further decreased, and the water flow is slowed down and does not splash out. The bottom walls  101  of the metal mesh  10  are generally the flat surfaces, and when the water flow flows by, a contact area of the water flow is small, an area where the water flow passes through is small, and resistance to the water flow is increased, thereby the flow rate of the water flow is further decreased, and the water flow gently flows out. When the bottom walls  102  decrease the flow rate of the water flow, the side walls  102  are in close contact with the mounting portion  21  for fixing the faucet outlet screen filter  1 , thereby ensuring that the faucet outlet screen filter  1  may not be displaced, and further avoiding that the faucet outlet screen filter  1  is washed out of the water outlet  23  or deviates from the faucet pipe  22 , and working capability of which is lost. The side walls  102  of the metal mesh  10  are curved surfaces, which is beneficial for the two baffles being in close contact the mounting portion  21 . Each of the side walls  102  further includes the extension edge  1021  extending outwards between the two baffles of the mounting portion  21 , which ensures that the metal mesh  10  does not have a large displacement, thereby ensuring that the faucet outlet screen filter  1  does not have a large displacement. Finally, the water flow gently flows out from the water outlet  23 , so as to achieve the target of the present disclosure. 
     The foregoing is only a preferred embodiment of the present disclosure, and certainly cannot limit the scope of the present disclosure, and a person of ordinary skill in the art may understand that all or some of the processes of the above embodiments are implemented, and equivalent changes made according to the claims of the present disclosure are still within the scope covered by the present disclosure.
