Abstract
Disclosed herein is a valve assembly disposed on a top surface of an air mattress and connected to a built-in air pump. The built-in air pump can comprise: a tube-like construction defining an inner cavity between the top surface and the bottom surface; a compression spring located within the inner cavity and attached to the top surface and the bottom surface; a bellow connected to a side surface of the tube-like construction, the bellow providing an air pathway from the inner cavity to the interior volume of the air mattress; a top end cap attached to a top portion of the compression spring and abutting the top surface; and a bottom end cap attached to a bottom portion of the compression spring and abutting the bottom surface.

A built-in air pump for an inflatable structure comprising:
- a valve assembly connected to a portion of the built-in air pump, the valve assembly comprising:
- a valve body, wherein the valve body comprises:
- a flat flange connected to a surface of the inflatable structure;
- and
- a wavy surface connected to the flat flange;
- a diaphragm valve positioned on a bottom portion of the valve body;
- a valve cap configured to attach to a portion of the valve body;
- and
- a cap gasket positioned within a portion of the valve cap.
A built-in air pump for an inflatable structure comprising:
- a valve assembly connected to a portion of the built-in air pump, the valve assembly comprising:
- a valve body, wherein the valve body comprises:
- a flat flange connected to a first surface of the inflatable structure;
- and
- a wavy surface connected to the flat flange;
- a diaphragm valve positioned on a bottom portion of the valve body;
- a valve cap configured to attach to a portion of the valve body;
- and
- a cap gasket positioned within a portion of the valve cap;
- a hollow structure in fluid communication with the valve assembly and defining an inner cavity;
- and
- a bellows connected to a side surface of the hollow structure, wherein the bellows provides an air pathway from the inner cavity to an interior volume of the inflatable structure.
A method of inflating an inflatable structure, the method comprising:
- depressing a valve assembly disposed on a first surface of the inflatable structure and connected to a built-in air pump, the valve assembly comprising:
- a valve body attached to the first surface of the inflatable structure, wherein the valve body comprises:
- a flat flange connected to the first surface of the inflatable structure;
- and
- a wavy surface connected to the flat flange;
- and
- a diaphragm valve positioned on a bottom portion of the valve body;
- applying a force to the built-in air pump by exceeding an outward force of air pressure exerted on the valve assembly, the built-in air pump comprising:
- a hollow structure defining an inner cavity between the first surface and a second surface of the inflatable structure;
- a compression spring located within the inner cavity;
- a bellows connected to a side surface of the hollow structure, the bellows providing an air pathway from the inner cavity to an interior volume of the inflatable structure;
- a first end cap attached to a first portion of the compression spring and abutting the first surface;
- and
- a second end cap attached to a second portion of the compression spring and abutting the second surface;
- contracting the compression spring and the hollow structure, thereby causing the first end cap to move toward the second end cap;
- and
- pushing air contained in the inner cavity through the bellows and into the interior volume due to the contracting.
