DEVICE FOR OPERATING ELECTRIC CLEANER BY PNEUMATIC GRINDER

摘要

PURPOSE: A device for operating an electric cleaner by a pneumatic grinder is provided to automatically operate the electric cleaner by operating the electric cleaner simultaneously with the operation of the pneumatic grinder. CONSTITUTION: A temperature sensor(37) is installed at an air passage(35) connecting an air compressor(31) and a pneumatic grinder(33), and is connected to a first power unit(39) and a voltage comparing unit(41). The temperature of the temperature sensor falls by the air when air in the air compressor is supplied to the pneumatic grinder. The voltage comparing unit outputs a high-signal to a switch(45), and the switch is on if the voltage supplied to the voltage comparing unit reaches the range of a setting voltage. Thus, the power of a second power unit(43) is applied to an electric cleaner(47) and the electric cleaner operates automatically.
