NEGATIVE ION ELECTRIC FAN

摘要

PURPOSE: A negative ion electric fan is provided to improve health of persons by fabricating the negative ion electric fan through mixing an electric stone powder with a raw material of a wing of the negative ion electric fan. CONSTITUTION: 1000g of a polystyrene chip, which is a raw material of a wing of a negative ion electric fan, is mixed with 50g of an electric stone powder, which is a raw material of a negative ion. 100g of a charcoal powder is added to the mixture. The mixture is inputted into an injection molding device so as to from the wing of a negative ion electric fan. Thus, the wing of the negative ion electric fan generates negative ions when the wing rotates.
