A foot pump, comprising:

• a housing, configured to be placed on the ground;
• a battery pack, arranged inside the housing and used as a power supply;
• an air pump, arranged inside the housing;
• an air pipeline, connected with an air outlet of the air pump and used for delivering compressed gas to an object to be inflated;
• a foot switch board, arranged on the upper surface of the housing for a user to touch with a foot or an object to trigger inflation operation;
• the air pump is connected with an air pump data detection module and an air pump power control module, the air pump data detection module is used for detecting an internal air pressure value of the object to be inflated, when the air pressure is lower than a set value, the air pump is automatically started through the air pump power control module to replenish air, and when the air pressure is automatically adjusted to the set value, the air pump automatically stops and maintains the pressure, achieving the functions of automatic pressure holding and automatic air replenishment.
