Nozzle structure in combination with a bidirectional air pump

Abstract

A nozzle structure has an air pump casing to receive therein the air pump and provided with an outlet defined through a bottom face of the air pump casing and a resilient plate detachably engaging with a peripheral edge defining the outlet of the air pump casing via a guiding element such that air pumped by the air pump is able to push the resilient plate away from the outlet when air is blowing out of the air pump casing and an air pump axle extending out from the air pump is able to push the resilient plate away from engagement with the peripheral edge of the outlet to allow air to flow into the air pump casing.

Description

CROSS REFERENCE [0001] This is a continuation-in-part (CIP) of patent application Ser. No. 10 / 733,082, filed on Dec. 11, 2003 by the same applicant of this application. The content thereof is incorporated for reference hereinafter.BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to a nozzle structure, and more particularly to a nozzle structure for a bi-directional air pump to readily facilitate pumping / drawing air into / out of an inflatable object. [0004] 2. Description of Related Art [0005] The existing inflatable objects normally are respectively embedded with an air pump to pump the air into the inflatable object when required. After the inflatable objected is inflated, a unidirectional valve in the air pump is used as a stop for preventing air from leakage from the inflatable object. When the inflatable object is not in use, the user will have to deflate the inflatable object manually so as to minimize the space occupied by the de...

AI Technical Summary

Benefits of technology

[0007] The primary objective of the present invention is to provide an improved nozzle structure and a bi-directional air pump to facilitate inflating and deflating the inflatable object.

[0008] In order to accomplish the aforementioned objective, the nozzle structure of the present invention is provided with a guiding seat movably attached to a peripheral edge defining an outlet of an air pump casing and a resilient plate securely engaged with a side face of the guiding seat such that when the air pump is actuated, the air pumped by the air pump will push the guiding seat together with the resilient plate away from the outlet of the air pump casing and when the inflatable object is inflated and the air pump stops functioning, the air pressure inside the inflatable object will push the resilient plate and the guiding seat back to engage with the peripheral edge of the outlet to seal the outlet. Thus air leakage is prevented.

[0009] Another objective of the present invention is that the air pump axle is able to abut a free end of a pole on the guiding seat when the bi-directional air pump is activated to draw the air inside the inflatable object out of the inflatable object such that the deflating process is facilitated.

Problems solved by technology

However, deflating the inflated object by hand is exhausting and too time consuming.
