Description

  The present invention can generate negative ions to settle airborne dust, select any fragrance from a plurality of fragrance sources, and emit fragrance. The present invention relates to an air purifying negative ion scent generator that can be cleaned and deodorized with indoor air using a compatible photocatalyst.

  Conventionally, there are few types of fragrance generators that can select any fragrance type with multiple fragrance sources at a low price, so the idea is to deodorize the last scent generated last time and emit a fresh fragrance. There was no model.

Conventionally, as a method of diffusing the fragrance liquid into the room, the shape memory alloy is energized and controlled by using both the operating force and heat generated by self-heating, and the fragrance is transferred and discharged from the fragrance container to the fragrance chamber for heating. A simple mechanism for evaporative diffusion has been developed. The following are known as the method and apparatus.

A dispenser pump is attached to the upper part of the fragrance container containing the liquid fragrance, a fragrance chamber with a lid is provided adjacently, and a plurality of rows of shape memory alloy wires are installed so as to be built in the lower portion of the fragrance chamber. , Heating the fragrance chamber that is in contact with the upper part using heat generation by self-resistance, and deforming and reducing the shape memory at a temperature exceeding the transformation temperature. Converted into operating force, pushes the dispenser pump, pipes the fragrance into the adjacent fragrance chamber, discharges it, and simultaneously opens the fragrance chamber lid with the vertical operating force via the link, evaporates and diffuses the fragrance. As a perfume device, Patent Document 1 of the prior application by the applicant himself can be cited as a known technique related to the present invention.
