The temperature control handwheel is vertically connected to the front end of the temperature control handle, and the bottom of the outer periphery of the temperature control handwheel is lower than the handwheel operation port. The opening of the thermostatic valve core cavity faces forward, and the axis of the thermostatic valve core's temperature control handle is set horizontally. The temperature control handwheel is vertically connected to the front end of the temperature control handle, and the bottom edge of the outer periphery of the temperature control handwheel is flush with the handwheel operating port.

4. The electric water heater with a built-in mechanical thermostatic valve according to claim 2, characterized in that: The temperature control handwheel is positioned near the front surface of the bottom outer casing.

5. The electric water heater with a built-in mechanical thermostatic valve according to claim 2, characterized in that: The bottom end of the outer casing has a recessed groove facing the side of the temperature control handwheel, corresponding to the handwheel operation port.

6. The electric water heater with a built-in mechanical thermostatic valve according to claim 1, characterized in that: The temperature control handwheel is in the shape of a flat disc, and the bottom edge of the outer periphery of the disc is exposed through the handwheel operation port. Alternatively, the temperature-regulating handwheel may be cylindrical, with the bottom end of the cylindrical circumference of the handwheel exposed through the handwheel operating port.

7. The electric water heater with a built-in mechanical thermostatic valve according to claim 1, characterized in that: The outer circumference of the temperature control handwheel is provided with an anti-slip structure.

8. The electric water heater with a built-in mechanical thermostatic valve according to claim 1, characterized in that: The valve body is equipped with anti-electric shock walls on the cold water outlet channel and the hot water inlet channel respectively.

9. The electric water heater with a built-in mechanical thermostatic valve according to claim 2, characterized in that: The surface of the main housing is provided with a display screen that shows the water temperature, and a temperature sensor is provided at the mixed water outlet channel of the built-in thermostatic valve, and the temperature sensor is connected to the display screen; Alternatively, the surface of the bottom shell may be provided with a display screen showing the water temperature, and a temperature sensor may be provided at the mixing water outlet channel of the built-in thermostatic valve, with the temperature sensor connected to the display screen.

10. An electric water heater incorporating a mechanical thermostatic valve as claimed in any one of claims 1 to 9, wherein: The valve body includes a first valve body and a second valve body and a third valve body disposed on both sides of the first valve body.
