Inflation pump

An inflation pump, comprising:

• a housing, provided with a storage groove extending along an outer surface of the housing in a circumferential direction, and a through hole in communication with the storage groove, wherein the storage groove comprises a first groove and a second groove in communication with the first groove, the second groove is wider than the first groove;
• an air source, disposed in the housing;
• a switch module, disposed in the housing and comprising an abutting arm passing through the through hole;
• a flexible protective member, disposed in the second groove and covering the abutting arm to prevent ingress of liquid or dust through the through hole;
• and
• a ventilation pipe, disposed in the housing and comprising a pipe body and a connector that is wider and more rigid than the pipe body and configured to be connected to a device to be inflated, the pipe body has one end passing through the housing and extending to the storage groove and another end connected to the connector, and the connector is shorter than the second groove;
• wherein the ventilation pipe comprises a first state and a second state with respect to the housing, wherein in the first state, the pipe body is stored in the first groove, the connector is stored and clamped in the second groove to abut against the abutting arm via the flexible protective member, and the air source stops working;
• and in the second state, the connector is separated from the second groove, to remove the abutting of the ventilation pipe against the switch module, and the air source works and is in communication with the ventilation pipe.
