Benefits of technology

The invention is a new air pump with a rotatable knob that has a plurality of baffles to muffle the sound of the airflow. The air pump has a primary chamber and a secondary chamber with a valve and a switch. The rotatable knob can be rotated to open or close the valve and the switch. The air pump has a sealing structure made of a pliable material to form an air tight seal. The invention solves the problem of air pumps creating too much noise during inflation and deflation.

Problems solved by technology

This can be time consuming and does not completely deflate the inflatable device, requiring a user to manually compress the inflatable device to push the remaining air out of the inflatable device.
Conventional air pumps on the market produce high levels of noise generated by the motor and by the airflow.

first embodiment

[0046]In a first embodiment, FIG. 2 shows rotatable knob 12 being connected to engagement knob 46. FIGS. 2, 5, and 6 depict engagement knob 46 having primary protrusion 47A and secondary protrusion 47B configured to engage switch 49B (FIG. 5). Engagement knob 46 is connected to rotatable chamber 18. Rotatable chamber 18 is retained by primary chamber 2. FIGS. 2 and 3A illustrate primary chamber 2 having port 6 located opposite recess 7. Primary chamber 2 is connected to secondary chamber 8.

[0047]FIGS. 4, 6, and 10 depict rotatable chamber 18 having ramp 17 bisecting rotatable chamber 18 into primary compartment 42 having primary port 19A and secondary compartment 43 having secondary port 19B. Rotatable chamber 18 has a primary end 23 located opposite secondary end 24. Secondary end 24 of rotatable chamber 18 has recess 22. In an embodiment illustrated in FIGS. 4 and 6, rotatable chamber 18 has shaft 26 having central bore 27. FIG. 6 best illustrates shaft 26 of rotatable chamber 18 ...

second embodiment

[0048]In a second embodiment, FIGS. 9 and 10 show rotatable chamber 18 having protrusions 25A and 25B, thereby, eliminating the need for interconnection with engagement knob 46. Rotatable chamber 18 has ramp 17 having primary side 20A located opposite secondary side 20B. Rotatable chamber 18 has shaft 26 having central bore 27. Shaft 26 has recess 28 configured to connect with an end of rotatable knob 12.

[0049]FIGS. 7, 8, 12, and 13 show the latching mechanism is formed when latching structure 38 of rotatable knob 12 is connected with recess 28 of shaft 26 of rotatable chamber 18.

[0050]FIG. 12 shows switch 49A not being engaged by protrusion 25A of rotatable chamber 18. Primary chamber 2 of housing 11 is in communication with port 6. Rotatable chamber 18 is oriented in a configuration which diverts air into an inflatable device (not shown), whereby, port 19A of rotatable chamber 18 is aligned with port 6. As rotatable chamber 18 is received further into primary chamber 2, protrusion...

Abstract

An air pump having a rotatable chamber in simultaneous communication with a valve and a switch during inflation and deflation of an inflatable device. The air pump housing has a rotatable knob connected to a rotatable chamber. The rotatable chamber has a ramp bisecting the rotatable chamber into a primary compartment and a secondary compartment. During inflation, the rotatable chamber is in communication with a valve and the port of the secondary compartment diverts the airflow from an opening of the rotatable knob in a direction into the inflatable device when the rotatable chamber is rotated to a primary position. During deflation, the rotatable chamber is in communication with a valve and a port of the primary compartment diverts the airflow out of the inflatable device, whereby, the airflow is exhausted through an opening of the rotatable knob when the rotatable chamber is rotated to a secondary position.

Description

BACKGROUND OF THE INVENTION1. Field of the Invention[0001]This invention relates, generally, to an air pump. More particularly, it relates to an air pump having a multi-functional rotatable chamber having a cam that activates a micro switch to power on and off the motor of the air pump, a ramp bisects the rotatable chamber into a primary compartment that diverts the flow of air in a direction into the inflatable device and a secondary compartment that diverts the flow of air out of the inflatable device, and a mode that seals air within the inflatable device.2. Background Art[0002]Currently, air pumps are used to inflate and deflate a variety of inflatable devices including, but not limited to, an air mattress, a bounce house, a chair, a cushion, a yard inflatable, or an inflatable prop. These air pumps are installed in the inflatable device and draw air in from one end and discharge air from another end into the inflatable device. Generally, when these inflatable devices need to be...
