[0031] When the device is damaged, if any of the transmission structure 11, the drive structure 12, and the temperature detection head 14 is damaged and it is necessary to close the valve body 1 to cut off the hot water supply, it is only necessary to manually turn the manual adjustment rod 7 downward to allow the manual adjustment rod 7 to drive the valve core 3 to seal the valve seat 2, so as to achieve the water cut-off of the valve without adding additional valves, thereby reducing material loss and cost.

[0032] The temperature detection head 14 in the device can detect the ambient temperature, thereby controlling the opening and closing of the valve core 3 through the controller 13 .

[0033] Further optimized solution, the transmission structure 11 includes a slide plate 1103, one side of the slide plate 1103 is vertically slidably connected to a guide slide bar 1101, the guide slide bar 1101 is fixedly connected to the inner side of the housing 10, the other side of the slide plate 1103 is vertically threadedly connected to a drive screw 1102, the drive screw 1102 is rotatably connected to the inner side of the housing 10, and the drive screw 1102 is transmission-connected to the drive structure 12;
