Provided is an air purifier with negative ions which can be removed, has a simple structure and can be easily used. It is a filter that firmly fixes titanium oxide. The material is water-soluble titanium oxide coated on carbon fiber that can withstand high temperatures, dried for a certain period of time, placed in a furnace at about 250 degrees, and fired. Filter sheet. SOLUTION: A carbon fiber filter 1 having a diameter of 40 mm and a thickness of 3 mm is attached along the inner periphery of a blue light emitting diode 2 having a diameter of 50 mm inside a ventilation hole of a negative ion air purifier, thereby performing an air cleaning action. An air purifier with a structure that removes various bacteria and odors that float from the air that flows in during operation.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The surface of the titanium oxide is illuminated with a blue light-emitting diode through a filter with titanium oxide applied to the air intake at the head of the negative ion air purifier housed in a cylindrical or prismatic container. As a result, organic compounds can be eliminated by reacting with moisture and oxygen in the passing air. The present invention is a technology for manufacturing a negative ion air purifier in which a light catalyst sterilization device is added to an air intake of a negative ion air purifier.

[0002]

[Prior art]

 Air purifiers using negative ion generators are manufactured by many companies, both for home use and for business use, and can be expected to have air purifying and deodorizing effects. Never before.

[0003]

[Objective of the invention]

 Removal of dust and deodorization in the air can be expected with a negative ion generator, but it was not possible to remove bacteria.The photocatalyst generated by irradiating titanium oxide with a blue light emitting diode glowed the air. The sterilization effect of the reaction between water and oxygen has made it possible to manufacture small and inexpensive equipment.

[0004]

[Means for Solving the Problems]

 Liquid titanium oxide is applied to the surface of an air filtration filter made of carbon fiber or the like, dried, placed in a furnace at 250 ° C. or more, and fired to produce a stable light catalytic filter. By irradiating the filter with light from a blue light-emitting diode effectively, a light-catalyzing effect is generated, and a bactericidal effect is generated by moisture and oxygen in the passing air, thereby eliminating various bacteria.

[0005]

[Action]

 A filter, coated with titanium oxide and fired, is installed in the air intake of anion-purified air, and the light emitted from the blue light-emitting diode mounted on the filter causes a light-catalyzing action, causing the filter to pass through the air. The bacteria contained are eliminated and the odor contained therein is reduced at the same time.

[0006]

[Embodiment of the invention]

 Attach an air intake fan to the top of the lid of the negative ion producing air purifier, and attach a filter coated with titanium oxide that has a photocatalytic effect to its inlet. A blue light emitting diode is arranged near this filter to eliminate bacteria and odor from the intake air by photocatalysis with titanium oxide. The filter used here is made of carbon fiber which can sufficiently withstand this temperature since titanium oxide is uniformly applied and then fired at a high temperature close to 250 ° C. As for the shape, a circular filter is used to receive uniform light, and a blue light emitting diode is used in a circular shape so that it can be attached to the outer periphery of the filter.

[0007]

【Example】

 In the present invention, a primary filter made of carbon fiber coated with titanium oxide, which is installed below an air intake of a negative ion generating air purifier-a blue light emitting diode arranged in close proximity to Fig. 1-1 The light of -2 removes harmful substances from the passing air by the photocatalytic effect with titanium oxide. The overall structure of the negative ion generating air purifier will be described with reference to FIG. 2 so that the present invention can be easily understood. The air that has flowed in from the air intake port shown in Fig. 2-4 passes through the carbon fiber filter coated with titanium oxide-Fig. 2-1. Harmful substances are decomposed and reduced and purified. Particles with relatively high molecular weight are captured by the secondary filter Fig. 2-2. The entire air flow is the sirocco fan for intake air. The air purified by the impeller in Fig. 2-6 and the negative ion high voltage generated by the operation of the electronic circuit for negative ion generation in Fig. 2-7 is the terminal for discharging. Fig. 2-8 Releases air into the air, further decomposes and absorbs the odors and the like remaining in the air purified by the photocatalytic effect, and releases the clean air containing a large amount of negative ions into the room. Is what you do.

[0008]

[Effect of the invention]

 All harmful substances that adhere to the living environment, such as organic compounds, bacteria, viruses, tobacco nicotine odor, trichloroethylene, formaldehyde, and dioxin, which float in the air, are all produced by the photocatalytic effect of titanium oxide and blue light-emitting diodes. Can be oxidatively decomposed into harmless substances. Hospital rooms, waiting rooms, nurses, rest rooms, geriatric homes in general, living rooms at home, bedrooms, for business use, majian stores, pachinko parlors, barber shops, pet shops, cars, etc. It is expected in many ways.
