In the present embodiment, the top of the auxiliary tank 12 is also in communication with the top of the main tank 11, but is not limited thereto.
In this embodiment, the detecting device includes an inductor, and when the liquid level of the cooling liquid 10 reaches the set position, the state signal of the inductor changes, and the main device receives the state change signal of the inductor, so as to send out an alarm. The set position is a limit of the allowable capacity of the cooling liquid 10 in the main tank 11, that is, the limit below which the cooling liquid 10 cannot be lowered or raised, and the limit of the cooling liquid 10 can be determined according to practical situations.

When the liquid is needed to be replenished, the first capacitive sensor 131 and the second capacitive sensor 132 are both above the liquid level, the first capacitive sensor 131 and the second capacitive sensor 132 are both in a first state, that is, the first capacitive sensor 131 is changed from a second state to a first state, at this time, the first capacitive sensor 131 is in a conducting state, the second capacitive sensor 132 is also in a conducting state, at this time, the relay is in a conducting state, and the liquid level signal is transmitted to the main device.
