Embodiment 1

[0028] Adopt the pad 1 of Fig. 1 shape, be 80mm with dimension C, be 112mm with dimension D, the area of ​​the first surface layer 21 is 45.4cm 2 The right outer humidifier 12a is used as an object, and the characteristics of the humidifier are evaluated. The humidifying part 12a has a cross-sectional structure as shown in FIG. 2 , Flocking non-woven fabric with a thickness of 1.5-2.5mm. The temperature regulating layer 24 is to use a weight per unit area of ​​73g / m 21. The thickness is 3 mm, the expansion ratio is 30 times, and the opening ratio of the through hole 23 is 30% of the foamed polyethylene cloth under the layer 24 . The heating element 26 in the heating part 12a, in addition to iron powder containing 95% by weight, the remaining 5% by weight is the base material of leech powder and wood powder as a water-retaining material, and activated carbon as an oxidation accelerator of 5% by weight. and saline with a salt concentration of 20% by weight. The impregnation ...

Abstract

The present invention improves the humidification pad used on the skin so that its temperature rises quickly and can maintain the required temperature for a long time. A humidification pad (1) has a heating element (26) between the first and second surface layers (21, 22). The heating element (26) contains metal powder, salts and water, and when oxygen is supplied through the air-permeable first surface layer (21), oxidation heat is generated to turn the water into steam. As the salt and water, the heating element (26) is impregnated with 17.5 to 26% by weight of salt water having a salt concentration of 18 to 22% by weight.

Description

technical field [0001] The present invention relates to a humidifying pad capable of supplying water vapor at an appropriate temperature to the skin of the face or other parts. Background technique [0002] Conventionally, humidifying pads that can be applied to the skin such as the face and supply water vapor to the skin are known. For example, Patent Document 1 discloses a water vapor generator as such a pad. The water vapor generating body is formed by wrapping the heating element containing metal powder, salt and water with a moisture-permeable thin layer material, which can generate 0.01mg / cm 2 ·Min above water vapor, the temperature of the water vapor is controlled below 50°C. In addition, the pad disclosed in Patent Document 2 has deformability suitable for use on the face. [0003] Patent Document 1: Japanese Patent No. 3049707 [0004] Patent Document 2: Japanese Patent Laid-Open No. 2004-358110 [0005] When a humidifying pad is applied to the face, etc., in a...
