A kind of sterilizing unit of multi-faceted automated biological identificationTechnical field
The utility model relates to be related to killing for Smart Home technical field more particularly to a kind of identification of multi-faceted automated biologicalBacterium device.
Background technique
Home interior space household goods are more and miscellaneous, and the space of some relatively secrets, such as lavatory, kitchen air notCirculation and moist, bacterium and cockroach easy to breed.Some building it is intensive and floor on the sunny side, the ground such as bedroom and parlor byIndoor every nook and cranny can not be shone directly into sunlight, will lead to acarid, bacterium largely breeds, make one to suffer from skin disease andImmunity reduces, the body Jiankang of serious infringement people.For this purpose, people are configured with chlorination equipment, such as disinfectant in daily lifeSprayer, air purifier and ultraviolet radiator bactericidal lamp.Disinfectant sprayer using trouble, it is necessary to periodically spray, air cleaningDevice is only used as air filtration to use, and can carry out killing disinfection to the germ in air, however can not be indoor to room a wide range ofSpace carries out sterilizing.Existing ultraviolet germicidal lamp then needs that ultraviolet light can be generated after manually opening switchSterilizing is carried out, there is a problem of inconvenient for use.
However, the one kind of ultraviolet light as nocuity light, can be divided into according to wavelength: near ultraviolet ray (UVA), far ultraviolet(UVB) and ultrashort ultraviolet light (UVC).Ultraviolet light is different the penetration degree of human skin.The wavelength of ultraviolet light is shorter, rightHuman skin harm is bigger.Short wave ultraviolet may pass through corium, and medium wave can then enter corium.Near ultraviolet ray (UVA) wavelength between315~400 nanometers, cloud layer can be penetrated, glass enters the room and interior, can penetrate to dermal layer of the skin, will cause it is tanned, andSkin aging, the main cause for wrinkle and cutaneum carcinoma occur.UVA can be sub-divided into UVA-2 (320~340nm) and UVA-1 (340~400nm).Wherein, UVA-1 penetration power is most strong, makes skin tanning up to skin corium, maximum to the nocuity of skin, but is also pairIt is easiest to ignorance, although especially in non-summer, UVA-1 intensity is weaker, but still exists, can accumulate because of long-timeAmount, causes skin damage.Especially skin aging relaxation, wrinkle, follow the string, melanin deposition etc..UVA-2 is then same with UVBSample reaches skin epidermis, it can cause skin sunburn, and redden sore and solar keratosis.The wavelength of middle-ultraviolet lamp (UVB)Between 280~315 nanometers, can be absorbed by stratospheric ozone, can cause shine injure skin it is red, it is swollen, hot and pain, serious person alsoIt can get blister or peel.For the wavelength of far ultraviolet (UVC) between 100~280 nanometers, wavelength is shorter, more dangerous, can be by ozone layerEarth surface will not be reached by obstructing, less likely infringement human skin.
Each individual is different to the tolerance degree of ultraviolet light, if sunshine cumulant will result in human body to a certain limitInjury.And the UV-C or high intensity UV-B and UV-A for being exposed to industrial equipment generation equally will cause the wound of eyes textura epidermoideaEvil.The ultraviolet wavelength of existing household ultraviolet lamp is usually UVC ultraviolet light, because its C-band ultraviolet light is easy to be given birth toThe DNA of object absorbs, especially best with the ultraviolet light of 253.7nm or so.Therefore, in practical residential use, can to user withAnd the pet cat and dog lamp of household constitutes unexpected irradiation injury.And existing ultraviolet radiator intelligence degree is low, cannot detectWhether surrounding has human body or pet to pass through, and is also possible to constitute unexpected injury to human body and domestic pets while sterilization.
