Description

A kind of Novel public toilet peculiar smell refreshing device

Technical field

The present invention relates to smart machine, more particularly to a kind of Novel public toilet peculiar smell refreshing device.

Background technology

For a long time, public lavatory peculiar smell is always an insoluble public hygienic environment problem, and the life with people ceases Manner of breathing closes.It is dirty with it is smelly be public lavatory common problem, in recent years water flushing system with cistern for closet development, solve dirty ask substantially Topic, but Peculiar Smell cannot be solved effectively always.

" taste of lavatory is too heavy, enters all to obtain first deep gas of taking a few mouthfuls of it every time and enters again, not so can swoon by smoked." can Can many people can all have the experience of such upper public lavatory, or even some higher gears time market, hotel, the toilet of fast food restaurant are being saved Such scene may also occur when holiday, peak traffic, the public lavatory of hospital is because being even more then the blind of health containing a variety of germs Area, many people smoking in public lavatory, smoke are spread in lavatory always.

At present, for lavatory peculiar smell problem, it is mainly the following solution.First, excreta is rinsed in time；2nd, Deodorization is carried out to urinal using camphor ball；3rd, smell cover is carried out using air freshener or santal；4th, using ecological lavatory Institute；5th, using air purifier.

First method is that root occurs from peculiar smell to propose solution, and existing market is mainly arranged using flushing system Let out washing away and isolating for thing.Excreta is discharged by the lavatory interior space by flowing water, to achieve the purpose that deodorization.Although this Kind method discharges excreta, but the smell of excreta still cannot be prevented to volatilize, and lavatory peculiar smell is hardly obtained improvement.

Second method is our common common deodorization modes in public lavatory Male urine pond, i.e. camphor ball deodorization. Camphor ball is to use sphere made of naphthalene, molecular formula C10H8.Also referred to as camphor ball.It can effectively remove the stench of urine, and valency Lattice are cheap, good deodorization effect.It is a kind of toxic chemical substance but naphthalene is industrial condensed-nuclei aromatics.Condensed-nuclei aromatics has carcinogenic Effect.Therefore, camphor ball is used for a long time in lavatory, not only pollutes environment, also there is huge infringement to health.

The third is to carry out smell cover using chemical freshener or santal, to reach " deodorization " effect.This method is first It can not first go to eliminate the unusual smell from root, covered simply by aromatic odors such as fresheners, illusive smell, takes stopgap measures and do not control This.Secondly, the long-term suction of chemical aroma material is still harmful or even carcinogenic.

4th kind is to build bio-toilet.Multiple-microorganism strain is introduced, competitively suppresses and kills the disease in excrement Pathogenic micro-organism, absorption, degraded, convert the stink substance produced in excrement, and passes through exhaust ventilation system, abundant pure and fresh public lavatory Environment.Although the method works well, bio-toilet cost is very high, is not suitable for common public lavatory and uses.

5th kind is to use air purifier.Air purifier species on the market is various, German Ai Jisen and Holland Philips's brand maintain the leading position in terms of air purifier, the air purifier developed, covers family expenses, commercialization, car The every field such as load.But these valuable products, volume is heavy, and is difficult that adaptation public lavatory humidity is big, corrosion is tight The various adverse circumstances of weight, bacterium.

It can be seen from the above that existing taste removal purification techniques, there are numerous shortcomings, public lavatory peculiar smell always cannot with hygienic issues Effectively solve, there is an urgent need to a product solved the problems, such as from source in market.

Embodiment

In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and examples The present invention is further elaborated.It should be appreciated that specific embodiment described herein is only to explain the present invention, not For limiting the present invention.

The global design scheme of the new public testing peculiar smell refreshing device of the present invention is as follows：

It is most of that whole device is divided into five：Context aware systems, high-pressure anionic generating means, active release device, place Manage control system, power supply stabilization circuit.During work, odor concentration sensor senses lavatory environment odor concentration, data reach list The processing of piece machine, control anion generation module produce specified quantitative anion, meanwhile, control fan 9 produces corresponding rotating speed, and wind is through going out Air passage 8, carries the anion that anionic shower nozzle 11 produces and is drained into the lump by air outlet 2 in air, and negative ion electrospray is smelly from decomposing Qi leel, plays the effect of the pure and fresh lavatory of intelligence.

(1) context aware systems

Premenstruum (premenstrua) investigates and experimental analysis, and the main component of peculiar smell is ammonia, hydrogen sulfide, methanol sulphur etc. in public lavatory.And not The ratio of same three kinds of components of public lavatory is variant.

To ensure the accuracy of sensing, using MQ-135 gas sensors, make gas sensitive using stannic oxide (SnO2), Stannic oxide to ammonia, sulfide, benzene series steam high sensitivity, the monitoring to smog and other pernicious gases is also highly desirable, Electrical conductivity increases and increases with polluted gas concentration in air, has in wider concentration range to pernicious gas good sensitive Degree.
