Problems solved by technology

Whether it is the trapping and killing of drugs, odors or chemicals, it will have certain adverse effects on the environment and even affect human health.
[0004] At present, there are devices that use lasers to kill mosquitoes and flies, but they are generally fixed and installed, and must be accompanied by a complex tracking and positioning system, which increases the cost of the equipment and has limited space for action.
Existing devices that use lasers to kill mosquitoes and flies basically use the thermal burning effect under strong light or high energy. Extinguished, easy to lose energy
[0005] At present, there are no examples or reports of using laser in sterilization and antivirus

Embodiment 1

[0034] like figure 1As shown, the moving mechanism in this example adopts a small hand-held four-wheeled cart commonly used in hospitals, including a moving mechanism box 1 , a partition 2 , a bottom plate 3 , a handle 4 , and casters 5 . Both the laser 6 and the optical path guiding system 8 are relatively fixed on the supporting plate 14, and then the supporting plate 14 is placed on the partition 2 and fixed by the quick fixing device 16. In this embodiment, a quick fixing clip is used. , when in use, connect the supporting plate 14 and the partition plate 2 through a ㄩ-shaped clip body, and then tighten the upper hand screw until the hand screw presses the supporting plate 14. The four corners and the bottom of the middle position of the supporting plate 14 are provided with shock-absorbing and anti-skid members 15, and rubber gaskets are used in this embodiment. The laser high voltage power supply 7 and the optical path guiding system power supply 11 are placed on the ba...

Embodiment 2

[0039] like image 3 , Figure 4 As shown, the laser 6 is a carbon dioxide laser, which outputs an infrared laser with a Gaussian distribution with a wavelength of 10.6 microns, a pulse peak power of 200 W, a pulse frequency of 5 khz, and a pulse width of 0.5 ms. The cylindrical lens 84 is placed parallel to the horizontal plane, and the reflected laser beam will expand into a line light source 17 perpendicular to the horizontal plane after passing through the cylindrical lens 84 . The motor 81 is fixed under the partition plate 2 (not shown in the figure), and the mirror 83 is driven to rotate around the axis perpendicular to the horizontal plane by the vertically arranged rotating bracket 82, so that the laser beam moves along the axial direction of the cylindrical lens 84, Further, it is transformed into a moving line light source 17 through the lenticular lens 84 to form a reflective scanning light curtain 13 .

[0040] Other structures are the same as in Example 1.

Abstract

The invention relates to a laser sterilizing and pest control method and device. Laser beams is generated by a laser device, the laser beams in Gaussian distribution are converted into a linear light source through a light path guide system, the linear light source scans in an outer space to form a light curtain, the light curtain is allowed to pass a target area through a moving mechanism, the laser forming the light curtain irradiates the bacteria or viruses in the target area to allow the protein on the outer layer of the bacteria or viruses to cure, the bacteria or viruses cannot absorb nutrition, and die, or the insects in the target area are irradiated and killed. The laser beams are clean without chemical pollution. The laser sterilizing and pest control device is simple in structure, simple to operate and easy to store, sterilizing and pest control in a large space can be achieved as long as power and action time are controlled properly, and human body damage can be avoided.

Description

technical field [0001] The invention belongs to the field of sterilizing and exterminating insects, and more specifically relates to a method and device for utilizing laser to sterilize and exterminate insects. Background technique [0002] Places such as hospital wards are places where various patients gather and move, and are also places where various bacteria and viruses breed, store, and multiply. These bacteria and viruses are usually excreted from the patient's body through the skin and mouth foam, attached to the bed, table and chair, and also attached to the dust in large quantities, free in the air. Or later, the air in the ward is filled with a large number of various pathogens. At this time, the air colony density of the ward is the largest, causing the chances of cross-infection among patients in the same room or patients in the same room during this period to increase greatly. [0003] Existing insect pests and germ prevention and control methods include drug k...
