AN AIR PUMP

An air pump for an inflatable product may include a pressure valve assembly and an inflation-and-deflation control assembly. The inflation-and-deflation control assembly may include a switch assembly operatively coupled to the pressure valve assembly and a pump assembly operatively coupled to the switch assembly. The switch assembly may have a first position and a second position, and the pressure valve assembly may be configured to engage the switch assembly to maintain the switch assembly in the first position or the second position. When the pressure valve assembly detects that a pressure threshold has been reached within the inflatable product, the pressure valve assembly may disengage from the switch assembly.

AN AIR PUMP WITH AN ELECTROMECHANICAL SWITCH ASSEMBLY

An air pump for an inflatable product may include an inflation-and-deflation control assembly, a pump assembly, a pressure valve assembly, and a linkage assembly. The pressure valve assembly may detect the pressure inside an inflatable chamber of the inflatable product. Once a pressure threshold is reached within the inflatable chamber, the pressure valve assembly may activate the linkage assembly. The linkage assembly may cause the inflation-and-deflation control assembly to deactivate the air pump and place the air pump in a closed or sealed position.

MULTI-PRESSURE INTEGRATED AIR PUMP

A high and low-pressure integrated air pump includes a single housing including an air inlet and an air outlet. A high-pressure pump is disposed within the housing and in fluid communication with the air inlet, and uses a first outlet passage to discharge to the air outlet. A low-pressure pump is also disposed within the housing and in fluid communication with the air inlet, and uses a second outlet passage to discharge to the air outlet.
