Abstract
This invention concerns a car cleaner and air pump shaped like an elephant. It can be used as a vacuum cleaner, e.g. sucking in dirt, and at the same time as an air pump, e.g. pumping pressurized air into a tire. This elephant-shaped car cleaner and air pump consists of an elephant-shaped cover, a dirt sucking device, an air pumping device, a lighting signaling device and an electric power system. The characteristic of the dirt sucking device is that dirt is sucked through the trunk and collected in the dirt bag set in the body by means of a blowing wheel turned by a motor. The characteristic of the air pumping device lies in pumping air by means of a cylinder and a piston that is moved by a set of worm-gear wheel and rod turned by the same motor that is used in the dirt sucking device.
