Air pump for air mattress

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...

AI Technical Summary

Benefits of technology

[0007]An objective of the present invention is to provide an air pump for an air mattress manually operated to rapidly inflate and deflate an air mattress, and providing shorter air path inside the air pump and faster inflation and deflation speed.

[0020]Differing from conventional air pump for an air mattress, the present invention employs the first air compartment or the second air compartment selectively aligned with the second air vent, and the air valve propped up by the undulant baffle on the mounting rack so as to switch to different operation mode. Structurally, the present invention is more flexible in arranging the layout of the first air vent and the second air vent which can be directly aligned each other. Consequently, such layout facilitates shortening 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.
