Abstract
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.
Claims17
An inflatable product comprising:
- an inflatable body being hollow and having a mounting cavity being formed within the inflatable body;
- an air pump device being mounted on the inflatable body and in the mounting cavity of the inflatable body and comprising
- a housing being mounted on the inflatable body and in the mounting cavity of the inflatable body and having
- an outer wall protruding out of the inflatable body;
- an inner wall being disposed in the mounting cavity of the inflatable body and being opposite to the outer wall of the housing;
- a first opening being formed through the outer wall of the housing;
- a first air room being formed inside the housing, extending from the outer wall to the inner wall of the housing and having
- an outer end corresponding to the outer wall of the housing and communicating with the first opening;
- and
- an inner end corresponding to the inner wall of the housing;
- a second air room being formed inside the housing, being disposed beside the outer wall of the housing, communicating with the inner end of the first air room and having a wall;
- and
- a second opening being formed through the wall of the second air room of the housing and communicating with the mounting cavity of the inflatable body;
- and
- a pumping assembly being mounted in the housing and having
- a motor being mounted in the housing between the inner end of the first air room and the second air room and having a shaft extending into the second air room;
- and
- a fan being mounted securely on the shaft, being mounted in the second air room and being driven by the motor;
- and
- a pressure releasing valve being mounted between the outer wall of the housing and the inflatable body, controlling communication between an interior of the housing and outside environment and releasing overpressure air in the inflatable body;
- wherein air flowing into the first opening is pumped to pass through the first air room, the motor and the second air room and to flow out of the second opening to dissipate heat of the motor in the housing.
