Abstract: A pump mechanism is provided, including a housing, a first impeller, a second impeller, and two driving modules. The housing includes a first recess, a second recess, a plate, a channel, an input pipe, a first output pipe, and a second output pipe. The plate is disposed between the first recess and the second recess. The channel passes through the plate and communicated with the first recess and the second recess. The input pipe is connected to the channel and passes through the housing and the plate. The first output pipe and the second output pipe are respectively communicated with the first recess and the second recess.

Abstract: A pump body includes a housing, a first and a second chambers separated and communicated by the housing, an input pipe communicated with the first chamber and an output pipe communicated with the second chamber. The input pipe has a water outlet located in the first chamber. The output pipe has a water inlet located in the second chamber. The first pump has a first rotor placed in the first chamber. The second pump has a second rotor placed in the second chamber, wherein an extension line of a rotating shaft of the second rotor is perpendicular to a plane where a rotating shaft of the first rotor located.

Abstract: A fan assembly structure is provided. The fan assembly structure comprises a fan, an air-flow guiding structure and a fixing component. The air-flow guiding structure has a plurality of air-flow guiding holes, a leaning portion and a plurality of first locking portions distributed on the leaning portion. The fixing component has a plurality of second locking portions. The fan is pivotally connected with the fixing component. The second locking portion is adapted to rotate by an angle with respect to the leaning portion to lock with the corresponding first locking portion. Thereby, the fan is disposed on the air-flow guiding structure by only the fixing component.
