[0024] See also Figure 1-4 , an embodiment provided by the present invention: a concealed low-pressure large-flow shower thermostatic faucet, comprising a main body 1, a large-flow thermostatic valve core 4, a panel 9, a check valve 10 and a stabilizing structure 17, a panel 9 is arranged above the main body 1, and a large-flow thermostatic valve core 4 is arranged above the panel 9, and the bottom end of the large-flow thermostatic valve core 4 penetrates the panel 9 and extends to the inside of the main body 1, thermostatic valve cavities 11 are opened inside the main body 1 on both sides of the large-flow thermostatic valve core 4, and a filter screen 2 is arranged at the bottom end of the thermostatic valve cavity 11, and a stabilizing structure 17 is arranged inside the thermostatic valve cavity 11 at the position of the filter screen 2;

[0025] The interior of the stabilizing structure 17 is provided with a retractable sink groove 1701, a threaded sleeve 1702, a hollow clip 1703, an adjusting stud 1704 and a compression spring 1705 in sequence. Three groups of retractable sink grooves 1701 are provided on the inner side wall of the thermostatic valve chamber 11, and the angle between adjacent retractable sink grooves 1701 is 120 degrees. A threaded sleeve 1702 is hinged on the inner side wall of the retractable sink groove 1701. The end of the threaded sleeve 1702 away from the inner side wall of the retractable sink groove 1701 is threadedly connected with the adjusting stud 1704, and a compression spring 1705 is fixed on the surface of the adjusting stud 1704. A hollow clip 1703 is installed on the end of the compression spring 1705 away from the adjusting stud 1704, and the surface of the hollow clip 1703 is tightly fitted with the surface of the filter screen 2.

[0026] When in use, the threaded sleeve 1702 on the inner wall of the sink 1701 is rotated to push the hollow clip 1703 to move under the action of the adjusting stud 1704, and then the compression spring 1705 on the surface of the adjusting stud 1704 pushes the hollow clip 1703 to clamp the filter 2, so as to prevent the filter 2 from loosening and deflecting during installation, thereby increasing the filtering effect when the faucet is used;

[0027] A check valve 10 is arranged inside the thermostatic valve cavity 11 above the filter 2, and an adjusting plug 3 is filled at the top of the thermostatic valve cavity 11 above the check valve 10, a locking sleeve 16 is threadedly connected to the top of the large-flow thermostatic valve core 4, an elastic gasket 12 is sleeved on the surface of the large-flow thermostatic valve core 4 above the locking sleeve 16, and an O-ring 15 is sleeved on the surface of the large-flow thermostatic valve core 4 above the elastic gasket 12 for sealing, and a thermostatic fixing tooth 5 is fixed on the surface of the large-flow thermostatic valve core 4 above the locking sleeve 16, and a water-dividing fixing tooth 8 is installed on the top of the large-flow thermostatic valve core 4 above the thermostatic fixing tooth 5;

A threaded through groove 14 is opened inside the handle 7, and a hollow cylinder 13 is filled on one side of the handle 7 above the threaded through groove 14 for fixing work. A threaded countersunk groove 6 is opened at the center position of the top end of the water-dividing fixed tooth 8.

[0029] Working principle: When in use, first rotate the handle 7 to drive the large flow thermostatic valve core 4 to rotate under the action of the thermostatic fixed teeth 5 and the water-dividing fixed teeth 8. In this process, open the hollow cylinder 13 and rotate the threaded through groove 14 on the top of the handle 7 to fix it with the threaded sink groove 6 on the top of the water-dividing fixed teeth 8 to achieve the temperature adjustment and switch dual adjustment functions of a single handle, thereby improving the convenience of using the faucet. Then, the locking sleeve 16 on the top of the large flow thermostatic valve core 4 cooperates with the elastic gasket 12 on the surface of the large flow thermostatic valve core 4 to adjust the temperature and switch the faucet. The O-rings 15 work with each other to prevent water leakage when the faucet is in use, thereby avoiding waste of water resources. Finally, the threaded sleeve 1702 on the inner wall of the retractable trough 1701 is rotated to push the hollow clip 1703 to move under the action of the adjusting stud 1704, and then the compression spring 1705 on the surface of the adjusting stud 1704 pushes the hollow clip 1703 to clamp the filter 2 to prevent the filter 2 from loosening and deflecting during installation, thereby increasing the filtering effect when the faucet is in use, and finally completing the use of the faucet.
