Example

[0030]With reference to FIGS. 1 to 9, an air pump for an air mattress has a housing (10), a chamber (101), a first air vent (102), a second air vent (103), a mounting rack (30) and a motor (40), an air valve (20).

[0031]The chamber (101) is defined inside the housing (10). The first air vent (102) is mounted on a top of the housing (10), communicates with the chamber (101), and is exposed beyond the air mattress in which the air pump is mounted. The second air vent (103) is mounted on a bottom of the housing (10) opposite to the top of the housing (10), and communicates with the chamber (101) and an inner space of the air mattress. The first air vent (102) and the second air vent (103) may be arranged to directly align to each other. The air valve (20) is mounted at the second air vent (103) to block or open the second air vent (103). The mounting rack (30) and the motor (40) are mounted inside the chamber (101) and located between the first air vent (102) and the second air vent (10...

Abstract

An air pump manually rotated to inflate and deflate an air mattress has a housing, a first and a second air vents mounted on the housing, an air valve selectively actuated to block or open the second air vent, and a mounting rack in the housing. The mounting rack is rotated so that a first or a second air compartment in the mounting rack is aligned with the second air vent, and the air valve is propped up by an undulant baffle on the mounting rack to switch to one of inflation, deflation and pressure hold-up modes. Given the structure of the air pump, the first and second air vents are flexibly arranged and can be respectively mounted on a top and a bottom of the housing and directly aligned with mutually. Therefore, the air path is shortened to make the inflation and deflation faster and more efficient.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention is related to an air pump for an air mattress, and more particularly to an air pump manually operated to rapidly inflate and deflate an air mattress.[0003]2. Description of the Related Art[0004]Air pumps are critical parts of inflatable air mattresses. Usually, air pumps are mounted inside the inflatable air mattresses for inflating and deflating air mattresses and also maintaining the pressure therein. As inflatable air mattresses can be used or stored by inflating and deflating it, they are widely used for traveling and going camping or providing a temporary bed.[0005]Currently, a conventional air pump for an air mattress has a housing, and a motor, an impeller, a solenoid valve, a slider and an air valve mounted inside the housing. An air vent and an air slot are respectively mounted on a side and a bottom of the housing. The air valve seals the air vent, and the slider corresponds to the air sl...
