Description

TECHNICAL FIELD

[0001] The present application relates to the field of pest killing, in particular, to a pest treatment device based on laser induction and killing. BACKGROUND

[0002] The prevention of pests, especially mosquitoes, is an important issue related to public health and health, and the traditional pest control technology is a light-induced pest control device. This type of device usually uses a light source of a specific wavelength to attract mosquitoes. When the mosquitoes approach, they are electrocuted by a high-voltage electric net or sucked into a collection box by the negative pressure generated by an internal fan. This mode of attraction has limited attraction to mosquitoes, and the pest entry rate is low. The high-voltage electric net type has the problems of electric shock noise and odor generation. The fan suction type may escape due to the strong flying ability of mosquitoes, and has a high risk of missed killing. In order to improve the accuracy of killing, a technical solution for killing mosquitoes using laser is proposed. For example, some disclosed technical solutions use a complex optical radar system to track and locate mosquitoes in flight in real time, and then control a high-power visible light or near-infrared laser beam to aim at the mosquitoes, which burns and kills the mosquitoes through thermal effect. The biggest problem of this solution is that the laser beam is directly exposed to the open environment. Once the high-power laser is accidentally reflected or the system fails, it is extremely likely to cause irreversible and permanent damage to the eyes of the operator, bystander or pet, which has a huge safety hazard.

[0030] In one embodiment, the inner wall of the optical induction channel 40 is a mirror surface, forming a deep and bright channel illusion full of "same kind" (mirror image), eliminating the vigilance of the pest and making it more willing to enter the channel. The pest treatment device based on laser induction and killing provided in this embodiment deeply integrates physical structure and optical deception, greatly enhancing the induction effect.

[0032] In one embodiment, a temperature sensing parking platform 304 is provided in the killing zone 30, the parking platform 304 is provided with a first heating mechanism 3041, so that the temperature of the surface of the temperature sensing parking platform 304 is maintained at 35-38 degrees Celsius.

After the first heating mechanism 3041 is heated, the heat is quickly and uniformly conducted to the surface of the temperature-sensing parking platform 304 through the metal substrate 3043, and is radiated outward through the dark biomimetic material layer 3042, attracting pests such as mosquitoes to stay, gaining time for laser killing and ensuring killing efficiency. Preferably, the surface of the dark biomimetic material layer 3042 is provided with a micron-level rough structure or a biomimetic hair structure to attract pests such as mosquitoes to stay.

[0034] In one of the specific embodiments, the temperature-sensing parking platform 304 includes N independent temperature control zones, N is an integer greater than 1, each temperature control zone is provided with a corresponding first heating mechanism 3041 and a temperature sensor 3044, and the device further includes a control unit 305 in communication connection with the temperature sensor 3044 and the light beam control mechanism 302.

For example, as shown in Figure 3 As shown, the temperature-sensing parking platform 304 includes a first temperature control zone 3040 and its corresponding first heating mechanism 3041 and temperature sensor 3044; a second temperature control zone 3040' and its corresponding first heating mechanism 3041' and temperature sensor 3044'; and a third temperature control zone 3040'' and its corresponding first heating mechanism 3041'' and temperature sensor 3044''. Each temperature sensor is in communication connection with the control unit 305.

[0035] In one of the specific embodiments, the dark biomimetic material layer 3042 is doped with a volatile pest attractant, which improves the broad-spectrum and comprehensive attractant efficiency of the device.

[0036] In one of the specific embodiments, a collection and processing unit 50 is further included, which is arranged corresponding to the killing area 30 and is used for collecting and processing the killed pests. The unit uniformly collects the pests for post-processing, avoids accumulation and corruption of the pests in the device, effectively prevents bacterial breeding and odor generation, avoids air pollution, and maintains the hygiene inside the device.

[0037] As shown in Figure 4As shown, in one of the specific embodiments, the collection processing unit 50 includes a beam splitter 501 and a transmission optical fiber 502, the beam splitter 501 is arranged on the light path of the laser 301, for splitting the deep ultraviolet laser beam emitted by the laser 301 into a first light beam and a second light beam, the first light beam is guided to the beam control mechanism 302 for killing pests, the incident end of the transmission optical fiber 502 receives the second light beam, and the outgoing end extends into the collection processing unit 50 for synchronous and in-situ irradiation disinfection of the insects and air therein. The transmission optical fiber 502 is made of high-purity synthetic quartz material and can efficiently conduct deep ultraviolet laser beams. The 266nm deep ultraviolet laser irradiation can effectively destroy the genetic material of harmful microorganisms such as viruses or bacteria carried by the insects, so that the harmful microorganisms lose physiological functions and die instantly. The pest treatment device provided in the embodiment surpasses simple "pest killing" and realizes in-situ inactivation of pathogens that may be carried by insect corpses, solves the public health hidden danger that the collection box of the traditional device becomes a "pathogen culture dish", and effectively kills microorganisms that are scattered from the insect bodies and fall into the collection processing unit. The laser irradiation of the air in the collection processing unit forms a "self-purification" microenvironment, ensuring that the air flowing out of the device is clean and avoiding cross contamination. The pest treatment device provided in the embodiment shares the same laser source through beam splitting technology, realizes "one light with two purposes", greatly improves the comprehensive efficiency and added value of the product without additional high-cost disinfection modules, and expands the application of deep ultraviolet laser from pest killing to continuous pathogen disinfection. The pest treatment device also becomes a high-efficiency "pathogen interceptor", which is particularly suitable for high-hygiene environments such as homes, hospitals, and food processing, and has great practical value and market prospects.

[0038] As shown, Figure 5 In one of the specific embodiments, the collection processing unit 50 is a closed high-temperature pyrolysis reaction chamber, and the bottom is provided with a second heating mechanism 503. The second heating mechanism 503 can be one of an electric heating film, a heating resistor, a PTC heating sheet, and a silica gel heating sheet. The second heating mechanism 503 can raise the temperature in the reaction chamber to above 150°C, so that the collected pests are heated to carbonization. The organic matter of the insect bodies is decomposed into carbon dioxide and water vapor at high temperature, and the remaining material is a small amount of sterile ash, which eliminates the generation of odor and the breeding of bacteria.
