[0005] The filtering mechanism comprises an annular filter screen and a groove arranged on the inner side of the shell, a filter element is arranged at the bottom of the inner groove of the groove, and two symmetrically distributed inserts are arranged on the outer end surface where the annular filter screen and the groove meet.

[0006] Preferably, two through grooves communicating with the bottom of the shell are arranged on the inner side of the shell, and the two through grooves are both provided with connecting horizontally distributed limiting grooves.

[0007] Preferably, the annular filter screen is provided with evenly distributed filter holes.

[0008] Preferably, a notch is provided on the annular filter screen at a position matching the water inlet hole.

[0009] Preferably, the groove is in the shape of a bucket that is larger at the top and smaller at the bottom, and an inclined surface is provided on the inner side of the groove.

[0010] Preferably, the filter holes distributed on the bottom layer of the annular filter screen are lower than the lower horizontal line of the water inlet holes and the water outlet holes opened on both sides of the shell.

[0011] Preferably, the assembly groove formed by the through groove and the limiting groove on one side is used in coordination with the embedding block.

[0012] By means of the above technical solution, the utility model provides a high-precision lead-free copper faucet valve core accessory, which has at least the following beneficial effects:

[0013] 1. Due to the setting of the filtering mechanism of the utility model, flowing water can be introduced into the shell through the gap connected to the water inlet hole on one side. At this time, under the cooperation of the filter holes of the annular filter and the filter element at the bottom of the groove, impurities in the flowing water can be intercepted and gathered to avoid long-term accumulation causing blockage inside the valve core body, ensuring smooth water flow and helping to increase the service life of the valve core.

[0014] 2. The utility model uses an integrally formed annular filter and an insert welded to the outside of the groove to enter through the bottom opening of the through groove, and then rotates the integrally formed annular filter and the groove in the shell so that the insert is placed at the inner end of the limiting groove, completing the assembly of the filter mechanism in the shell, realizing the convenient quick disassembly of the filter mechanism in the shell and reducing maintenance costs.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Based on the technical problem of the long-term accumulation of impurities in the flowing water causing the internal blockage of the valve core proposed in the above prior art, please refer to Figure 1-Figure 4 This is an embodiment of the utility model: a high-precision lead-free copper faucet valve core accessory, including a shell 1, a handle 2 for controlling the opening and closing of the faucet is welded on the shell 1, the structural material of the combination of the shell 1 and the handle 2 is lead-free copper, and the shell 1 is also penetrated by a water inlet hole 3 and a water outlet hole 4 for forming a water flow path.

[0024] Among them, in order to solve the problem of long-term accumulation of impurities in the flowing water causing clogging inside the valve core, a filtering mechanism 5 for intercepting water impurities is installed on the inner side of the shell 1 in the technical solution. Its specific structure includes an annular filter screen 51 and a groove 52 arranged on the inner side of the shell 1. The annular filter screen 51 and the groove 52 are integrally formed, and the annular filter screen 51 is provided with evenly distributed filter holes. The groove 52 is in the shape of a bucket with a larger top and a smaller bottom, and the inner side of the groove 52 is provided with an inclined surface. Through the bucket-shaped groove 52 with a larger top and a smaller bottom, and under the guidance of the inclined surface provided on the inner side of the groove 52, the intercepted impurities can be guided into the bottom of the inner groove of the groove 52. The bottom of the inner groove of the groove 52 is embedded with a spliced ​​filter element 53, and the intercepted impurities can be gathered and collected through the filter element 53. The impurities that come down are welded on the outer end faces where the annular filter screen 51 and the groove 52 are connected. Two symmetrically distributed inserts 54 are welded. Two through grooves 6 that are connected to the bottom of the shell 1 are opened on the inner side of the shell 1. The two through grooves 6 are installed with connected transversely distributed limit grooves 7. The through grooves 6 and the limit grooves 7 on one side form an L-shaped groove on the side of the inner cavity of the shell 1. The assembly groove formed by the through grooves 6 and the limit grooves 7 on one side is used in conjunction with the insert 54. The insert 54 welded on the outside of the integrally formed annular filter screen 51 and the groove 52 enters through the bottom opening of the through groove 6, and then the integrally formed annular filter screen 51 and the groove 52 are rotated in the shell 1, so that the insert 54 is placed at the inner end of the limit groove 7, and the assembly of the filtering mechanism 5 in the shell 1 is completed.

[0025] Among them, in order to form a water flow path, a notch 55 is opened on the annular filter 51 in the present technical solution at the position of the water inlet hole 3, and the notch 55 is connected with the water inlet hole 3. The filter holes distributed on the bottom layer of the annular filter 51 are lower than the lower horizontal line of the water inlet hole 3 and the water outlet hole 4 opened on both sides of the shell 1. By operating the rotary handle 2, the water inlet hole 3 on the shell 1 welded at its lower end is connected to the water inlet pipe port, and the water outlet hole 4 is connected to the water outlet pipe accordingly, forming a smooth water flow path.
