Embodiment
The utility model is a kind of laser sterilization and disinfestation device, comprising: the laser instrument 6 that produces laser beam; Light path reflective scan system 8, with laser beam reflection to the external space and make laser beam outside spacescan form reflective scan light curtain 13; Travel mechanism, laser instrument 6 and light path reflective scan system 8 are located in the travel mechanism.Wherein, light path reflective scan system 8 comprises speculum 83, runing rest 82 and motor 81.Speculum 83 be positioned on the light path of laser beam and form less than 90 ° of angles with input path, the adjustable angle of speculum 83 is controlled the diameter of formed reflective scan light curtain 13 by adjusting this angle.In addition, can adjust the formation position of reflective scan light curtain 13 by adjusting the light path (promptly adjusting the relative position of laser instrument 6 and light path reflective scan system 8) of laser beam.Preferred, laser instrument 6 comprises laser bodies 61, and is used to the mobile base 62 that supports laser bodies 61 and adjust its setting angle, after laser instrument 6 installs, still can adjust its angles by mobile base 62.The version of mobile base 62 is various, as long as can realize the setting angle of fine setting laser bodies 61.Speculum 83 is located at runing rest 82 ends, and motor 81 drives speculum 83 rotations by runing rest 82.As long as runing rest 82 can drive speculum 83 rotation do not have simultaneously and can block laser beam.Described laser instrument 6 is the nitrogen molecular laser of output Ultra-Violet Laser, or the carbon dioxide laser of output infrared laser.Described travel mechanism comprises castor 5 or handle 4, makes things convenient for the people to move and parks.For ease of moving, device also comprises laser instrument high voltage source 7, the light path reflective scan system power supply 11 that is installed in the travel mechanism.Light path reflective scan system power supply 11 can adopt the 12V accumulator, removes the trouble of traction 220V mains-supplied line from.Laser instrument 6 and light path reflective scan system 8 can be directly installed in the travel mechanism.For ease of changing travel mechanism or being easier to be used in combination with existing travel mechanism, preferably, as shown in Figure 2, with laser instrument 6 and light path reflective scan system 8 both position relative fixed be arranged on the support flat board 14 dull and stereotyped 14 removable being located in the travel mechanism of this support.For support flat board 14 can be disassembled from travel mechanism fast, can realize by more existing rapid fixings, for example quick geometrical clamp 16 etc.The influence that vibration when moving in order to reduce travel mechanism brings for the light path of dull and stereotyped 14 tops of support, and increase coefficient of friction, dull and stereotyped 14 bottoms of support also can be provided with damping and slide-prevention spare 15, for example are provided with rubber sheet gasket in the bottom at dull and stereotyped 14 4 angles of support at least.
The utility model by laser beam outside spacescan form the light curtain, and mobile light curtain makes the light curtain through the target area; Bacterium or virus in the laser irradiation target area of formation light curtain make the protein coagulating of its surrounding layer can't draw nutrition and death, and the insect in the irradiation target area makes the born death of its flap.Preferably, described laser instrument is that output wavelength is the nitrogen molecular laser of the Ultra-Violet Laser of 337 nanometers, pulse peak power 300kW, pulse frequency 5hz, pulsewidth 10ns, or output wavelength is 10.6 microns, the carbon dioxide laser of the infrared laser of pulse peak power 200W, pulse frequency 5khz, pulsewidth 0.5ms.Pulse peak power plays conclusive effect to sterilization and disinfestation.Because the burst length pulsewidth is very short, so peak power can be very big, the molecule of bacterial virus can change under this laser (mainly being Ultra-Violet Laser) impulse action immediately, and when a plurality of laser pulse continuous actions, bacterial virus will be dead; Killing the mosquitos and flies insect mainly is to use infrared laser, at this moment mainly utilizes the fuel factor of pulsed infrared laser light high-peak power, directly burns the mosquito of running into the light curtain to death.Because pulsewidth is very short, be harmless therefore simultaneously to people and animals.Regulate moving of light curtain according to the actual mosquito density in the target area during practical operation, density greatly then moves and slows down.
Each parts in the laser sterilization and disinfestation device exist with compound mode, can replace or change certain parts separately according to actual conditions, maintain easily, can reconfigure according to actual needs, it is other that for example the power supply of laser instrument 6 also can be placed on laser instrument 6, perhaps design the power supply of output channel more than, provide the electric energy of laser instrument 6 and light path reflective scan system 8 simultaneously respectively, perhaps the travel mechanism in the specialized designs specific environment (being example only in this manual) with the small-sized hand steered four-wheel go-cart commonly used in the hospital.
As shown in Figure 1, the external space of speculum 83 let-off gear(stand)s that the light that laser instrument 6 sends is rotated continuously, spacescan becomes a width of cloth reflective scan light curtain 13 outside.The people drives travel mechanism, make any locus in whole room all will be subjected to the laser beam scanning radiation, swimming aerial virus and bacterium will be because of being subjected to surpassing the ultraviolet light of doses or the irradiation of infrared light, the protein of its surrounding layer can be solidified, and is hedged off from the outer world, can't draws nutrition and death.In addition, device of the present utility model also can be applicable to plant, utilizes the stronger quick scanning space of infrared laser, and optionally kill mosquitos and flies and do not damage livestock, also be favourable and environmental protection to developing animal husbandry.Local sterilization and disinfestations such as the workshop that also can be used for general restaurant, kitchen, family, school, production environment having relatively high expectations, laboratory, range of application is very extensive.
Below in conjunction with accompanying drawing and object lesson the utility model is further elaborated, but the utility model is not limited to this specific examples.
As shown in Figure 1, 2, what the travel mechanism in this example adopted is the small-sized hand steered four-wheel go-cart commonly used of a hospital, comprises travel mechanism's casing 1, dividing plate 2, base plate 3, handle 4, castor 5.Be arranged on the support flat board 14 to laser instrument 6 and light path reflective scan system 8 both position relative fixed, and then support flat board 14 is positioned on the dividing plate 2, fixing by rapid fixing 16, adopt quick geometrical clamp in the present embodiment, with the clamp clamping by the ㄩ type of support dull and stereotyped 14 and dividing plate 2, the hand-screw screw that screws the top then compresses support dull and stereotyped 14 until the hand-screw screw and gets final product during use.Be provided with damping and slide-prevention spare 15 at four angles of support flat board 14 and the bottom of medium position, adopt rubber sheet gasket in the present embodiment.Laser instrument high voltage source 7 and light path reflective scan system power supply 11 are placed on the base plate 3.What light path reflective scan system power supply 11 adopted is the accumulator of 12V.The present embodiment compact conformation can be parked in a little place, and each parts exists with syntagmatic, can change separately, maintains easily.
