[0015] By further configuring the above, it is possible for customers to understand the water temperature in the base, and no external power supply is required to power the display screen, making assembly more convenient.

[0016] The present invention is further configured as follows: the check valve has a built-in valve hole and a valve disc for controlling the opening and closing of the valve hole; the water inlet end and the water outlet end of the check valve are connected via the valve hole; the valve disc is slidingly arranged in the check valve; a return spring and a spring mounting frame are also provided in the check valve; one end of the spring mounting frame is fixedly arranged on the check valve, and the other end is provided with a guide column; the guide column is arranged along the sliding track of the valve disc; the return spring is sleeved on the guide column; one end of the return spring abuts against the spring mounting frame, and the other end abuts against the valve disc.

[0017] With the above-mentioned further arrangement, when water enters the water inlet end of the check valve, the force of the water flow will compress the reset spring, thereby causing the valve disc to slide and separate from the valve hole, thereby making the water inlet end of the check valve and the water outlet end of the check valve conductive and allowing water to discharge. When the water inlet end of the check valve stops entering, the reset force of the reset spring and the force of water backflow cause the valve disc to come into contact with the valve hole, closing the valve hole and preventing water from flowing back. The guide column can prevent the reset spring from deviating from its original position when in use. BRIEF DESCRIPTION OF THE DRAWINGS
