Description
- This application claims the benefit of Chinese Patent Application No. 200520073478.3, filed on Jul. 6, 2005. The disclosure of the above application is incorporated herein by reference.
- The present disclosure relates to a power tool combination and a synchronization control device for controlling the power tool combination.
- Power tools used in combination and a synchronization control device for controlling the power tool combination are known. For example, a known synchronization control device controls a power sander and a vacuum cleaner running in synchronization. Such a synchronization control device is generally arranged in a first power tool (such as the vacuum cleaner) and the first power tool supplies power to a second power tool (such as the power sander) to run synchronously with the first power tool. A switch signal of the second power tool controls the first power tool to be powered-on or powered-off synchronously with the second power tool. However, such an arrangement has a disadvantage. That is, the two power tools are supplied power by a common electrical wire arranged in the first power tool. Therefore, the general working current (power) is limited by the current capacity of the inlet wires on the first power tool. This is especially disadvantageous for countries with low-voltage domestic power supplies. With this arrangement, the electrical wire must be very thick, thereby increasing manufacturing costs.
- An aspect of the present disclosure is to provide a power tool combination and a synchronization control device thereof which can control the power tool combination running in synchronization. The power tool combination may be powered by different power sockets and different routes.
- The present disclosure relates to a power tool combination including at least a first power tool and a second power tool. The first power tool has a first electrical wire. The second power tool has a second electrical wire. The first electrical wire connects terminally to a first plug. The second electrical wire connects terminally to a second plug. The first power tool is electrically connected to a signal receiving device (e.g., a radio-signal receiving device). The signal receiving device has a power switch for controlling the first power tool. The second power tool is electrically connected to a signal transmitting device (e.g., a radio-signal transmitting device). When the second power tool is activated, the signal transmitting device emits an effective signal, the signal receiving device receives the effective signal, and the power switch of the first power tool is in a conduction state.
- The present disclosure further relates to a synchronization control device used for a power tool combination which includes a first power tool and a second power tool. The synchronization control device comprises a signal transmitting device being electrically connectable to the first power tool and capable of emitting an effective signal. A first electrical circuit is formed between the signal transmitting device and the first power tool. The synchronization control device also comprises a signal receiving device being electrically connectable to the second power tool and capable of receiving the effective signal from the signal transmitting device. A second electrical circuit is formed between the signal receiving device and the second power tool. The first electrical circuit and the second electrical circuit are insulated from each other and control the first and second power tool to run in synchronization when the signal receiving device receives the effective signal from the signal transmitting device.
- The present disclosure further relates to a synchronization control device including a signal receiving device electrically connected to a first power tool and a signal transmitting device electrically connected to a second power tool. The signal receiving device has a power switch for controlling the first power tool, wherein when the second power tool is started, the signal transmitting device emits an effective signal, the signal receiving device receives the effective signal and the power switch is in a conduction state.
- The present disclosure has the advantage that first and second power tools are synchronously powered-on or powered-off via signal transmission between the signal transmitting device and the signal receiving device. The signal transmitting device and the signal receiving device are formed in independent circuits with the second and first power tools respectively. This makes the power of the power tool combination unlimited by the current capacity of inlet wires and lowers manufacturing costs.

- The signal transmitting device may be mounted on the first power tool and the signal receiving device may be mounted on the second power tool.
- The signal transmitting device and the signal receiving device may be electrically insulated from each other and mechanically attached to each other.
- The synchronization control device may be fixedly mounted to one of the first or second power tools, wherein the signal receiving device and the signal transmitting device may be mechanically connected but electrically insulated from each other and electrically connected respectively to the first power tool and second power tool.
- The signal transmitting device may be arranged out of and electrically connected to the second power tool and the signal receiving device may be mounted on and electrically connected to the first power tool.
