Abstract
The present invention relates to a projector with an air purifying function. A photocatalytic material is added in a public known projector, and is positioned on a path which is formed from a refrigerating device and is flowed across by cooling air, and simultaneously, the photocatalytic material is positioned at the side of a light source assembly. The surrounding oxygen and molecules are excited to active free ion radicals by acceleration through the catalytic action generated by that ultraviolet light generated by the light source assembly radiates the photocatalytic material. Then, the generated free ion radical is blown out of a projector body through the flow of the cooling air. Because the decomposition of organic substances and gases are accelerated by the free ion radical, an air cleaning effect can be generated.
Description
Technical field
The present invention relates to a kind of projector, particularly a kind of projector with air purifying function.
Background technology
When using projector, generally be one darker indoor, just can being projected on the screen with the image distinctness.Indoor for avoiding outdoor light to inject, usually can be on door and window wait to shut out the light, but when shutting out the light with heavy curtain, the door and window of ventilating air is also blocked by heavy curtain, causes not circulating of room air with heavy curtain.In the majority Room that exists together, when perhaps the smoker exists together a Room, can generation make us foreign odor, the dust of being accumulated in the stale air, pathogeny body more can damage human body.
Summary of the invention
Therefore, an object of the present invention is to provide a kind of projector, when an airless indoor use projector, with indoor air purifying with air purifying function.
Projector with air purifying function of the present invention is to increase by a catalysis material in known projector.Catalysis material is positioned on the path that cooling air that cooling device causes flows through, and is positioned at the next door of light source assembly simultaneously.The UV-irradiation catalysis material that utilizes light source assembly to produce produces catalytic action, oxygen around quickening and molecular excitation become to have active free ion base, circulation by cooling air again, the free ion base that is produced is blown out outside projector's body, because of the decomposition of free ion base quickening organic substance, gas, so can produce the air cleaner effect.
For above-mentioned and other purposes of the present invention, feature and advantage can be become apparent,, and in conjunction with the accompanying drawings, be described in detail below below especially exemplified by a preferred embodiment:

Embodiment
Below will clearly demonstrate spirit of the present invention with accompanying drawing and detailed description, as those skilled in the art after understanding preferred embodiment of the present invention, certainly can be by the technology of teachings of the present invention, change and modification, it does not break away from spirit of the present invention and scope.
Shown in Figure 1 is the projector with air purifying function of a preferred embodiment of the present invention.As shown in Figure 1, the projector with air purifying function of the present invention comprises a power supply unit 100, a signal processing part 200, a light source assembly 300, an optical processing portion 400, a control part 500, a cooling device 600 and a catalysis material 700.Power supply unit 100 provides projector's each several part required electric power.Signal processing part 200 becomes the signal of video signal that projects with the electronic signal process of input.Light source assembly 300 provides the light source of a projection usefulness corresponding to gradation.The light that optical processing portion 400 penetrates with light source assembly 300, the signal of video signal that signal processing part 200 is handled is projected to screen.Cooling device 600 guides to internal body with as cooling air with the air of the outer normal temperature of projector's body, absorbs after the heat of internal body generation, and the cooling air that heats up is discharged outside the body, and cooling device 600 can be a fan.Control part 500 is in order to the various variable quantities of the control each part mentioned above of automatic or manual.And being positioned at cooling air that cooling device 600 caused, the catalysis material 700 of feature of the present invention flows through on the path, be positioned at the next door of light source assembly 300 simultaneously, UV-irradiation one catalysis material 700 that utilizes light source assembly 300 to be produced, produce catalytic action, oxygen around quickening and molecular excitation become to have active free ion base (being negative ion), circulation by cooling air again, the free ion base that is produced is blown out outside projector's body, because of the decomposition of free ion base quickening organic substance, gas, so can produce the air cleaner effect.
Shown in Figure 2 is near the catalysis material 700 of Fig. 1 enlarged diagram, and as shown in the figure, light source assembly 300 comprises a projection lamp 310 and a reflection lampshade 320.Light source assembly 300 emits beam with projection lamp 310, collection via reflection lampshade 320, penetrate visible light from reflection lampshade 320 opening parts, projection lamp 310 also radiation ground Transflective lampshade 320 penetrates the sightless ultraviolet light of human body naked eyes, generally speaking, the lamp of a 300W can produce the ultraviolet light above 15W.Under the irradiation of ultraviolet light, make catalysis material 700 produce catalytic action, oxygen around quickening and molecular excitation become to have active free ion base (being negative ion), utilize the free ion base to destroy the energy of organic gas molecule more in advance, with the airborne scent molecule of quick decomposition, dust or pathogeny body, in order to reach the purpose of air cleaner.
In technological thought scope of the present invention, can carry out application implementation miscellaneous, for example, common catalysis material 700 can have for example: titania, titanium dioxide, zinc paste, tin ash and cadmium sulfide, wherein titania is because of avirulence and have preferable redox ability and chemically stability, so be a preferable catalysis material.The preferred embodiment of Fig. 1 and Fig. 2 is so that photoactivation material 700 quickens the generation of negative ion, but in addition, also can set up anion generating device in projector waits and increases negative ion quantity, as shown in Figure 3 and Figure 4, also can use electric anion generating device 710, add a voltage when electric anion generating device 710, the first end parts of cilium will discharge negative ion, the voltage that puts on electric anion generating device 710 is then supplied with by power supply unit 100, controls the generation of negative ion automatically or manually by control part 500.As shown in Figure 5, an also available tourmaline 720 is as anion generating device, and tourmaline is a natural anion generator, does not need irradiating ultraviolet light and apply voltage forever to discharge negative ion.Suchlike application implementation also should be included in the claim of the present invention.
By the invention described above preferred embodiment as can be known, use the present invention and have following advantage:
1. when using projector, discharge negative ion in air from projector, with negative ion with indoor air purifying.
2. the use of the ultraviolet light collocation catalysis material of the Transflective lampshade ejaculation of the application radiation of ignorance originally is with the quantity of raising negative ion, by the airborne scent molecule of negative ion accelerated decomposition, dust or pathogeny body, to reach the function of air cleaner.
Though the present invention discloses as above with a preferred embodiment; yet it is not in order to limit the present invention; any those skilled in the art; without departing from the spirit and scope of the present invention; certainly can do various change of control part and retouching, so protection scope of the present invention should be with being as the criterion of being defined when right claim scope.
