Abstract: The present invention is related to a driving structure of a low noise pneumatic clipper, and an object of the present invention is to use a compressed air in order for driving a cutting comb. The present invention includes a main body, a cutting comb installed on the front side of the main body, and a driving means installed in the inside of the main body to operate the cutting comb. In the present invention, in the inside of the main body, a driving compartment is formed on the center part of the main body to separate the cutting comb from the driving means and a ventilation chamber is formed to surround the driving compartment and to form an inner wall of the main body. the driving compartment and the ventilation chamber are connected by a passing through hole which is position on the upper side of the passing through hole and is connected to an exhaust pipe.

Abstract: The present invention is related to a heating device used in a rod for permanent wave, which controls capable of heating the rod electrically and effectively. In particularly, the present invention is related to a heating device with easy maintenance and safety and a rod for permanent wave with improved structure, which can overcome a problem of sensing a temperature of the heating device and a problem of inefficient electrical heating of the rod for permanent wave. An object of the present invention is to handle the problems by providing a rod for permanent wave having a relatively strong durability as well as an excellent thermal conductivity, and a heating device for electrically heating the rod for permanent wave with the most effective way.

Abstract: The present invention is related to a silent hair dryer for supplying a warm current of air, and to a pipe system for using in beauty shop. The pipe system supplies an air of constant pressure and fixed quantity. the present invention is characterized in that the pipe system is installed in the inside of a beauty shop, and the pipe system has a compressor, an air flowing pipe, a discharging wall socket, a hose and a hair dryer. The compressor inhales an air from the outside to generate a compressed air and discharges the compressed air to the outside. The air flowing pipe is connected to an outlet of the compressor, and the compressed air is supplied from the compressor flowing through the air flowing pipe. The air flowing pipe is laid in a ceiling and an edge of wall surface of the beauty shop to be led to the lower part of a chair.
