An air leak proof regulating structure of a mechanical pump

A structure for selectively inflating one or more air chambers of an inflatable product, the structure comprising:

• a body;
• an air pump positioned within the body;
• a plurality of air interfaces provided on the body, each air interface being coupled to a respective air chamber of the inflatable product;
• a channel selector having an operator actuatable input actuatable from an exterior of the body and a turntable;
• a switch operatively coupled to the air pump to in a first state turn on the air pump and in a second state to turn off the air pump;
• and
• a plurality of seals, each seal being positionable in a first position to contact a respective one of the plurality of air interfaces to seal the respective one of the plurality of air interfaces and in a second position to be spaced apart from the respective one of the plurality of air interfaces to permit air flow therethrough;
• wherein a single actuation of the operator actuatable input controls both the state of the switch and the position of each of the plurality of seals.

A multi-channel pump, comprising:

• a body having a first air chamber interface and a second air chamber interface;
• an air pump assembly arranged in the body;
• a channel switch structure arranged in the body including a first post rod aligned with the first air chamber interface and a second post rod aligned with the second air chamber interface;
• a panel covering an opening in the body;
• and
• a regulator structure comprising
• a channel selection knob rotatably arranged on the panel,
• a turntable arranged in the body, an upper end of the turntable is coupled to the channel selection knob, and a lower end of the turntable interfaces with the channel switch structure to selectively move the first post rod and the second post rod to, in turn, selectively open and close the first air chamber interface and the second air chamber interface, and
• a power switch actuatable by an outer periphery of the turntable to selectively activate the air pump assembly.
