Abstract:
An air chamber device comprising: an air pump comprised of an elastic body having an upper elastic part and a lower elastic part connected together to define an interior space, at least one through-hole formed in the upper elastic part for introducing ambient air into the interior space, and a first air discharge valve connected to the elastic body for discharging air therethrough from the interior space when pressure is applied to the upper elastic part of the elastic body to elastically deform same while closing the through-hole to thereby reduce a volume of air in the interior space, and for preventing back-flow of air therethrough into the interior space when the pressure applied to the upper elastic part is released and the through-hole is opened so that ambient air is introduced through the through-hole and into the interior space; an air chamber connected to the air pump for receiving air discharged by the first air discharge valve; and a second air discharge valve for discharging air from the air chamber.
