Abstract

PURPOSE:To improve cushioning performance by quickly drying a hot water drip generated in space by holding the space forged between a hair brush and the outer surface of a brush base part by a projection. CONSTITUTION:The space S between a brush base 5 and the brush base part 3 can be held with the projection 20 when the brush is not used. Therefore, steam discharged from a steam discharge opening 6 intrudes from a gap between the outer peripheral wall of a steam discharge opening 42 and the inner periphery of the steam discharge opening 6 and a gap between the hole of the brush base 5 and the base part of a bristle 4 to the space S. Even when dew condensation due to the contact of the steam with the internal plane of the brush base 5 cooled by the outside air, the hot water drip of the dew condensation is adhered closely between the brush base 5 and the outer surface of the brush base part 3, which prevents them from being adhered. The steam is heated by coming in contact with the outer surface of the brush base part 3 heated at high temperature by the heat conduction of a heater 23 and heated by conduction or radiation can be quickly dried by high temperature air that flows in the space S. Since the projection 20 can supply the cushioning performance to the brush base 5, brushing can be performed without giving pain on the head skin.

However, in the above-mentioned conventional example, steam penetrates into the gap between the outer surface of the brush base and the inner surface of the brush base, and condenses to form dewdrops. It was easy for the water droplets to stay without drying and to adhere to the outer surface of the brush base portion with the inner surface of the brush base interposing the water droplets. If the water drops are tap water drops, they will be scales, and will accumulate with dust and become unsanitary.If the water drops are a treatment lotion, the brush base or brush base will be liable to chemical deterioration and corrosion. Occasionally, a foul odor was generated.

Therefore, an object of the present invention is to enhance the quick-drying property of steam and water droplets between the brush base and the elastic brush base in such a steam hair brush, and prevent clinging between the brush base and the brush base. There is a point to do. Another object of the present invention is to enhance the cushioning property so that brushing can be performed while caring for hair without giving a sensation to the scalp.
