US 2026/0054367 A1 · ADAPTER AND POWER TOOL

Abstract

An adapter includes: a power input terminal for connecting an AC power supply; a power circuit that performs energy conversion on the inputted AC power to obtain electrical energy capable of powering a power tool; and a tool interface connected to a power interface of the power tool to output electrical energy. The adapter further includes a data transmission module connected to at least the tool interface and capable of outputting first communication data and/or first internal resistance data to the tool interface so that the power tool is capable of identifying the adapter according to the first communication data and/or the first internal resistance data. The first communication data includes at least adapter identification data, and the adapter identification data enables the power tool to identify that a connected device is the adapter between the adapter and a battery pack.

Dependent claims

An adapter, comprising:

a power input terminal that connects an alternating current (AC) power supply;
a power circuit that performs energy conversion on inputted AC power to obtain electrical energy to power a power tool;
a tool interface that connects to a power interface of the power tool and outputs electrical energy;
and
a data transmission module that connects to at least the tool interface and outputs first communication data and/or first internal resistance data to the tool interface so that the power tool is capable of identifying the adapter according to the first communication data and/or the first internal resistance data;
wherein the first communication data comprises at least adapter identification data, and the adapter identification data enables the power tool to identify that a connected device is the adapter between the adapter and a battery pack.

A power tool, comprising:

a tool body;
an electric motor disposed in the tool body;
a power interface that connects to a battery pack or an adapter;
and
a control circuit having a plurality of control modes to control operation of the electric motor, the control circuit comprising a data acquisition module connected to at least the power interface to acquire battery pack data transmitted by the battery pack or acquire adapter data transmitted by the adapter, and a controller that controls the electric motor to operate in a first constant power mode when the controller identifies, according to the battery pack data, that the power interface is connected to the battery pack and controls the electric motor to operate in a second constant power mode when the controller identifies, according to the adapter data, that the power interface is connected to the adapter;
wherein output power in the first constant power mode is different from output power in the second constant power mode.
