[0089] The method for inflating the underwater camera device of this example is as follows:

[0090] S1: Loosen the cover 2 and take out the second sealing ring under the cover 2;

[0091] S2: The top column 64 of the inflation head 6 is pressed against the end surface of the upper section 31 of the support member 3 to lower the support member 3 by a certain distance (e.g., 2-3 mm); an air pump is connected to the other end of the inflation head 6 to perform inflation operation;
