A head for an air pump, comprising:
- a housing extending from a first distal end to a second distal end and including a first compartment extending therein from a first end defined at the first distal end of the housing to a second end, with the second end of the first compartment enclosed by an end wall, and with the housing further including a hole extending therethrough and into the first compartment;
- a nozzle device disposed within the first compartment of the housing;
- an urging mechanism including a cam disposed in the first compartment of the housing and abutting against the nozzle device, an axle inserted into the housing through the hole and engaged with the cam, with the axle rotatable with respect to the housing, with the cam rotatable with the axle, and with the urging mechanism further including a pivoting member connected to the cam by engaging with a terminal end of the axle, with the pivoting member rotatable with the axle;
- and
- an end cap engaged with the first distal end of the housing;
