Abstract

A foot warming pad able to generate heat by itself is composed of the external bag made of plastics, the internal bag made of slightly air-permeable non-woven fabric, and the heat generating material prepared from iron powder, inorganic salt, activated carbon, water and wood powder and put in said internal bag.

Description

technical field [0001] The invention relates to a foot warming article, more specifically, relates to a self-heating foot pad utilizing chemical reaction. Background technique [0002] All there is uneconomical, inconvenient defect in the most commonly used local heating technology at present. There are those that utilize the heat produced by chemical reactions as the heat source of the hot compress physiotherapy heating bag. For example, the application numbers of the Chinese invention patent publication are: 93117958.0, 94112561.0, 92112917.3, etc. The records are all kinds of heating that utilize the heat released when the sodium acetate solution is crystallized. supplies. But the price of sodium acetate is high, and it is easy to overflow from the bag in liquid state, so the market prospect is very bad. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in...
