An inflatable product has an air pump device and a pressure releasing valve. The air pump device has a housing and a pumping assembly. The housing has two openings as an inlet opening and an outlet opening. The pumping assembly is mounted in the housing and has a motor and a fan. The motor is mounted between the inlet and outlet openings and drives the fan. Consequently, mounting the motor between the first opening and the second opening dissipates the heat of the motor because the air passing by the motor cools the motor. The pressure releasing valve is adjusted by users and releases air while pressure of air in the inflatable body reaches a predetermined pressure level. |
