Air pump for air mattress

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.

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 for rapidly inflating and deflating 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]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 slot. The air valve is con...

AI Technical Summary

Benefits of technology

[0007]An objective of the present invention is to provide an air pump for an air mattress featuring with shorter air path inside the air pump and faster inflation and deflation speed.

[0016]Differing from conventional air pump for an air mattress, the present invention mainly employs the actuating mechanism to move the slider and the sloping partition of the slider to prop up the air valve so as to switch to different operation mode. Structurally, the present invention has greater flexibility in layout of the first air vent and the second air vent, which can be directly aligned with each other. Consequently, such layout shortens the air paths inside the air pump, rendering a fast and efficient inflation and deflation speed of the air pump for an air mattress.

Problems solved by technology

Despite the inflating and deflating features owned by the conventional air pump, there are still many problems of the conventional air pump yet to be improved, especially poorly fitting structural elements reducing efficiency and poor air flow path, specifically, the air valve and the slider are all activated by the rod of the solenoid valve.
