Detailed Description

The present invention will be described in further detail with reference to examples, but the embodiments of the present invention are not limited thereto.

Examples

As shown in FIGS. 1-3, the utility model discloses a pipe joint head with filtering capability, including the casing that has inner chamber 10, install the filtering mechanism 8 inside inner chamber 10. Specifically, this casing includes upper cover 1 and lower cover 2, as shown in fig. 4, 5, upper cover 1 is provided with water outlet 3 and water inlet 4, and upper cover 1 lower extreme is provided with connecting portion 9, and lower cover 2 is then connected with connecting portion 9 through the screw thread, therefore lower cover 2 can be followed upper cover 1 and dismantled. The water outlet connector 3 and the water inlet connector 4 are both communicated with the filter cavity 12, and when the water outlet connector 3 and the water inlet connector 4 are used, the water outlet connector 3 and the water inlet connector 4 are respectively connected with two pipelines.

For better connecting the pipelines, the water outlet connector 3 and the water inlet connector 4 are both provided with clamping heads 5, as shown in fig. 3.
