Embodiment Construction

[0037] The present subject matter provides a number of hybrid power tools that avoid the need for external or separate power converters. These hybrid tools can be powered by connecting one end of a conventional electrical extension cord directly to the tool, and connecting the other end of the extension cord into an AC electrical outlet. In certain versions of hybrid tools, the tool does not have any cords permanently attached to the tool, but instead uses a power cord outlet along the outer area of ​​the tool. However, it should be understood that in some versions the tool and / or tool system may include a power cord that is permanently or selectively releasable attached to the tool.

[0038] The subject matter also provides a hybrid tool or tool system capable of being powered by one or more batteries or battery packs, or alternatively capable of being powered by a connection to an electrical outlet such as a 120-volt AC power outlet) to supply power. In some embodiments, a...

Abstract

Electrical devices such as tools or tool systems are described which receive electrical power from either a separable battery or an electrical power cord. In certain versions, the tools include both apower cord receptacle and a battery receiving region located along the exterior of the tool housing. The tools can be configured such that when a battery is powering the tool, connection of a power cord to the tool is precluded. The tools can also be configured so that when a power cord is connected to the tool, connection of a battery is precluded. In particular, a hybrid drain cleaning tool system is also described that includes a hybrid drain cleaning tool in combination with a separable battery. Also described are hybrid powered threader devices and hybrid powered saw devices.

Description

technical field [0001] This topic concerns tools capable of operating using electrical power from different sources. In particular, the subject matter relates to drain cleaning tools powered from AC or DC power using a power cord or cable and / or batteries. Background technique [0002] Power tools are known to be capable of being powered by a removable battery, which in many cases is rechargeable, or by a separate power converter connected to an electrical outlet, usually using a power cord and / or a conventional extension cord . In some cases, the converter can be configured to connect to the tool like a battery. Accordingly, such converters have been shaped to match the shape of the corresponding battery at least in the part of the converter that engages the tool. When using battery power, the tool can convert direct current (DC) from the battery to alternating current (AC) if the tool uses an AC electric motor. Alternatively, when using a converter connected to an AC e...
