The digital display self-generating discovery of the embodiment has the following use process:

as shown in fig. 1 to 11, when the valve core is used, hot water enters the fourth hole 1221 of the stator 122 from the first hole 1212 of the base body 121, and then enters the water passing chamber 2001 from the first water passing opening 22 corresponding to the rotor 2. After entering the fifth hole 1222 of the stator 122 from the second hole 1213 of the base body 121, the cold water enters the water passing chamber 2001 from the corresponding first water passing opening 22 of the rotor 2. The cold water and the hot water are mixed in the water passing cavity 2001 and enter the accommodating cavity 33 from the third water passing port 321 to drive the impeller 5 to rotate. After the water in the accommodating cavity 33 flows from the seventh hole 322 of the second holder body 32 to the second water passing opening 23 of the rotating member 2, the water flows from the sixth hole 1223 of the fixed piece 122 to the third hole 1214 of the base body 121, and then flows out to realize water outlet.

When the temperature of the discharged water needs to be adjusted, the installation base 3 and the rotating piece 2 are driven to rotate through the rotating operation part 7, the communication areas of the two first water passing openings and the hot water inlet and the cold water inlet are adjusted, the proportion of the cold water and the hot water entering the water passing cavity 2001 is changed, and temperature adjustment is achieved.

The impeller 5 is driven by the mixed water to rotate, so that the rotating shaft 41 of the generator 4 rotates, the generator 4 generates electricity to supply power to the digital display assembly 9, automatic electricity generation is realized, and energy is saved. Meanwhile, the resistance value of the temperature sensing element 10 changes with the temperature of the mixed water in the accommodating cavity 33. The digital display component 9 displays the temperature corresponding to the resistance value of the temperature sensing element 10 according to the resistance value of the temperature sensing element 10.

In the embodiment, since the mounting base 3 of the hydroelectric power generation device is in rotation-stopping connection with the rotating piece 2, the operating part 7 of the rotating hand wheel is in rotation-stopping connection with the mounting base 3, and when the operating part 7 is rotated, the mounting base 3 is driven to rotate together with the rotating piece 2. The mounting seat 3 of the hydroelectric power generation device can tightly abut against the rotating piece 2 to seal the water passing cavity 2001, and a sealing ring can be additionally arranged to seal the water passing cavity 2001. Because there is no relative motion between the hydroelectric power generation device and the valve core body 1, the contact surface between the hydroelectric power generation device and the valve core body is not abraded. The elastic sealing ring is arranged in the embodiment to seal the water passing cavity 2001, so that the elastic sealing ring is not abraded, and the service life of the sealing ring is not shortened. The description of the above specification and examples is intended to illustrate the scope of the invention, but should not be construed as limiting the scope of the invention. Modifications, equivalents and other improvements which may be made to the embodiments of the invention or to some of the technical features thereof by a person of ordinary skill in the art through logical analysis, reasoning or limited experimentation in light of the above teachings of the invention or the above embodiments are intended to be included within the scope of the invention.
