In an aspect, an inflatable object includes an object body enclosing a chamber to receive air, and a valve mounted to the inflatable object body, including a valve body defining a passageway between the chamber and an ambient environment. The valve body has a shoulder. The valve body defines an outside end, which opens to the ambient environment, and an inside end, which opens into the chamber. The valve includes a one-way flap that is movable between an open position to permit fluid communication between the chamber and the ambient environment through the passageway, and a closed position. The one-way flap is biased to the closed position with a closing force selected to be overcomable to move the one-way flap to the open position by an airflow having a speed that is less than about 48 m/s, and which is at a pressure lower than 1 atmosphere.

A fluid pressure regulator includes at least one fluid inlet conduit for connection to a pressurised fluid source, an outlet conduit. and an elastically expansible chamber arranged between the at least one fluid inlet conduit and the outlet conduit. The elastically expansible chamber being configured to elastically deform the at least one fluid inlet conduit upon expansion to modify the cross sectional area of the at least one fluid inlet conduit.

An air valve assembly includes a housing defining an internal channel, a plunger member positioned in the internal channel and configured to slide relative to the housing, a biasing member positioned in the internal channel and configured to apply a biasing force onto the plunger member, a sealing member defining a first inflation aperture, the plunger member slidably received by the first inflation aperture, a second deflation aperture defined by the housing and in fluid communication with the internal channel, and a deflation control member slidably connected to the housing, the deflation control member configured to selectively seal the second deflation aperture.

The disclosed technology includes an air valve assembly for providing flexibility for a user when inflating an inflatable air mattress. The air valve assembly can include a base configured to attach to a portion of the inflatable air mattress, a middle valve configured to attach to the base portion and having a first diameter, a diaphragm member configured to attach to the middle valve, and a cap configured to removably couple to a portion of the air valve. The assembly can further include an adapter configured to detachably attach to the middle valve portion. The adapter can have a portion with a second diameter that is smaller than the first diameter such that when the adapter is attached, a user may use an inflation device with a smaller dimensioned output.

A constant pressure valve for an inflatable product is provided. The constant pressure valve comprises: a housing defining an airflow channel within. A first sealing seat is disposed in the airflow channel and a first through hole is formed in the first sealing seat. An inflation valve core comprises: a first actuating assembly and a first valve head. The first actuating assembly is configured to drive the first valve head to disengage from the first through hole, or to engage with the first through hole in a sealing manner. The constant pressure valve is switchable between an inflation state, in which the first valve head is disengaged from the first through hole, and the airflow channel is unblocked; and a cut-off state in which the first valve head is engaged with the first through hole in a sealing manner, and the airflow channel is blocked by the first valve head.

A valve nozzle structure for an inflatable cushion includes an outer body, an inner body, and a diaphragm member. The diaphragm member is assembled in the inner body. The inner body is assembled in the outer body. The valve nozzle structure is able to provide one-way inflation with an automatic check function and deflation. The outer body further includes a holding plate configured to release the sealing state of the diaphragm member. Thus, the valve nozzle structure can achieve an automatic and continuous deflation function. The inner body is detachably connected to the outer body, which is beneficial for maintenance and replacement of the parts.

An air valve assembly for use with inflatable articles is provided. The air valve assembly includes a valve base (10), a valve body (20), an inflation adapter (30), a plug (40) and a fixing ring (50). The air valve assembly provides for inflation of the inflatable article through two different sized air passages, allowing inflation by multiple sizes of air inflation hoses or nozzles. The air valve assembly also provides for quick deflation of the inflatable article through a third and larger sized air passage. The configuration of the air valve assembly may be easily changed by hand without the need for tools, allowing for easy and efficient inflation or deflation of the inflatable article.

A method for manufacturing a self-sealing valve for an inflatable body such as a toy balloon is disclosed. The method comprises immersing a mold in an immersion bath of an elastomeric material in liquid form and heating the mold in a heating device until a hollow tube element of an elastomeric material with a proximal end, a distal end, a cylindrical portion at the proximal end, a flat portion at the distal end having two flat sides, and a transition portion between the cylindrical portion and the flat portion is formed. The cylindrical portion is open at the proximal end and the flat portion is closed at the distal end with an opening on at least one of its flat sides. The valve is inserted in an inflatable body with the flat and transition portions of the hollow tube element located inside the inflatable body.

In an aspect, an inflatable object includes an object body enclosing a chamber to receive air, and a valve mounted to the inflatable object body, including a valve body defining a passageway between the chamber and an ambient environment. The valve body has a shoulder. The valve body defines an outside end, which opens to the ambient environment, and an inside end, which opens into the chamber. The valve includes a one-way flap that is movable between an open position to permit fluid communication between the chamber and the ambient environment through the passageway, and a closed position. The one-way flap is biased to the closed position with a closing force selected to be overcomable to move the one-way flap to the open position by an airflow having a speed that is less than about 48 m/s, and which is at a pressure lower than 1 atmosphere.

An air valve assembly includes a housing defining an internal channel configured to receive a first member, the first member is fluidly connected to an air source, a plunger member positioned in the internal channel and configured to slide relative to the housing, a biasing member positioned in the internal channel and configured to apply a biasing force onto the plunger member, and a sealing member positioned in the internal channel and defining a first inflation aperture, the plunger member slidably received by the first inflation aperture. In a first inflation configuration, the first member is configured to form a magnetic connection with the sealing member and contact the plunger member to overcome the biasing force, the plunger member is configured to responsively slide relative to the first inflation aperture to facilitate a flow of air between the sealing member and the plunger member.
