Abstract
An air pump for an air mattress has a housing, a first air vent and a second air vent respectively mounted on a top and a bottom of the housing, a chamber, a blower and an air direction switcher mounted in the chamber, an actuating mechanism, and an air valve. A slider in the air direction switcher is moved by operating the actuating mechanism being a solenoid valve or a knob gear and a follower. The air valve is propped up by a sloping partition of the slider to open the second air vent. Given the structure of the air pump, the first and second air vents are flexibly arranged and can be directly aligned with each other. Therefore, the air path is shortened to inflate and deflate more rapidly and more efficiently.
Claims16
An air pump for an air mattress, comprising:
- a housing having
- a chamber defined in the housing;
- a first air vent mounted on a top of the housing, communicating with the chamber and adapted to be exposed beyond an air mattress;
- and
- a second air vent mounted on a bottom of the housing, communicating with the chamber, and adapted to communicate with the air mattress;
- a blower mounted in the chamber and having
- a first air compartment having an air outlet formed through a bottom of the first air compartment and directly aligned with the second air vent;
- a second air compartment adjoined with the first air compartment, communicating with the first air compartment through a first opening formed through a first partition between the first air compartment and the second air compartment, communicating with the first air vent through a second opening formed through a second partition of the second air compartment opposite to the first partition and abutting the first air vent, and having an air inlet formed through a bottom of the second air compartment and directly aligned with the second air vent;
- an impeller located in the first air compartment;
- and
- a motor driving the impeller to rotate and generate air flow;
- an air direction switcher mounted in the chamber and having
- an actuating mechanism moving in a straight line;
- and
- a slider connected with the actuating mechanism, having a cavity, alternately moved by the actuation mechanism to align the cavity to the air inlet and the air outlet, and having a sloping partition thereon;
- and
- an air valve mounted at the second air vent propped up by the air flow generated by the motor and the impeller while inflating and by the sloping partition while deflating to open the second air vent.
