7. The temperature control valve with a detection device according to claim 1, characterized in that: The main body (1) of the temperature control valve includes a valve cover (10) for fixing the motor (4). A connecting post (15) is provided on the valve cover (10). The connecting post (15) extends upward along the valve cover (10) and is fixedly connected to the motor (4). The vertical gap between the motor (4) and the valve cover (10) forms an installation groove for accommodating and installing the transmission component (6).

8. The temperature control valve with a detection device according to claim 1, characterized in that: The thermostatic valve body (1) includes a valve body (11), which has a first water inlet (18) and a second water inlet (19) facing each other; or, the first water inlet (18) and the second water inlet (19) are located on the same side of the thermostatic valve body (1). The valve core (3) and the valve body (11) are connected by a water inlet chamber (22) and a temperature regulating chamber (24). The first water inlet end (18) is connected to or disconnected from the water inlet chamber (22) by the rotation of the valve core (3); the second water inlet end (19) is connected to or disconnected from the temperature regulating chamber (24) by the rotation of the valve core (3). The first water inlet (18) is connected to the water inlet chamber (22), and the second water inlet (19) is connected to the temperature control chamber (24) so ​​that the liquids from the two water inlets are mixed in the temperature control chamber (24).

9. The temperature control valve with a detection device according to claim 8, characterized in that: The valve body (11) is provided with a first water outlet (20) and a second water outlet (21). The second water outlet (21) is located on the bottom of the valve body (11) and is connected to the temperature regulating chamber (24). The liquid in the temperature regulating chamber (24) is output to the outside of the valve body (11) through the second water outlet (21). The first water outlet (20) and the first water inlet (18) are located on the same side of the valve body (11). The valve core (3) is provided with a liquid guide groove (23). When the valve core (3) is rotated to the position angle where the first water outlet (20), the liquid guide groove (23) and the first water inlet (18) are connected, the liquid entering the first water inlet (18) enters the first water outlet (20) along the liquid guide groove (23).
