NOVELTY - An oxygen generating device (20), comprises first pipe (231) extending through top of first side portion (23) and second pipe (241) extending through top of second side portion (24); and positive electrolytic post (232) inserted in the first side portion, a negative electrolytic post (242) inserted in the second side portion, and a power source (30) connected to the positive electrolytic post and the negative electrolytic post.    USE - For connection to a frame of an exercising device to provide oxygen to the user.    ADVANTAGE - The device employs electrolytic process for water to generate oxygen which is directly provided to the users. By the electrolytic process, oxygen is generated and goes out from the first pipe and hydrogen is generated and goes out from the second pipe which is lead to outside of the room.    DETAILED DESCRIPTION - An oxygen generating device, comprises:    (1) a container (21) having a first side portion, a second side portion and an intermediate portion (22), the intermediate portion located between and in communication with the first and second side portions, each of the first side portion, the second side portion and the intermediate portion having a top, the top of the intermediate portion being lower than the two respective tops of the first and second side portions;    (2) a first pipe extending through the top of the first side portion and a second pipe extending through the top of the second side portion, the container adapted to be filled with water, the first pipe adapted to be lead to users; and    (3) a positive electrolytic post inserted in the first side portion and a negative electrolytic post inserted in the second side portion, a power source connected to the positive electrolytic post and the negative electrolytic post.
