After the host receives the response data, the upper cover controls the exhaust valve according to the response data.

As an achievable implementation, if the duration of data transmission is considered, then the duration required for the power receiving end to send the first data to be sent is t2, and the power transmitting end sends the second data to be sent. When the time required for the data to be sent is t3, the time length T of the transmission cycle satisfies the conditions shown in the following formula:

T>t1+t2+t3.
