Abstract:
A quick-replacement multi-functional household tool, which is characterized by comprising a power body and several functional heads (2) that can be used in a replaceable manner, wherein the power body is internally provided with an electric motor (11) and a control circuit board (16); a key-type locking fastener (3) is arranged in the power body; the functional heads (2) are inserted into the power body to be fixedly connected to the key-type locking fastener (3); an output shaft (111) of the electric motor (11) is connected to input ends of the functional heads (2), and the electric motor drives the functional heads to work; each functional head (2) is internally provided with an identification resistor having a different resistance value; the power body is detachably connected to one functional head (2) when working; the identification resistor sends a signal to the control circuit board (16); and the control circuit board (16) controls the electric motor (11) to switch to a corresponding working mode. The quick-replacement multi-functional household tool has the following advantages: the household tool has one body and a variety of heads; the heads are removed by pressing the locking fastener, thereby realizing quick replacement of the heads, and also realizing convenience and quickness; the heads are internally provided with the identification resistors for changing a driving form of the electric motor; and the control circuit board can change the driving form of the electric motor according to the identification resistors, thereby protecting the heads.
