Description

Technical Field

[0001] The invention relates to the technical field of mosquito killing devices, and in particular to a circular scanning laser mosquito killing device. Background Art

[0002] Mosquitoes are the most familiar pests. In addition to directly biting and sucking blood, causing pain and itching, and disturbing sleep, mosquitoes are also the vectors of many infectious diseases. The mosquito-borne diseases in my country include malaria, lymphatic filariasis, epidemic encephalitis B, dengue fever, and dengue hemorrhagic fever.

[0003] At present, the mosquito killing devices sold on the market mainly include the following two categories:

[0004] The first category is the mosquito killing device based on adsorption, which usually uses a fan to generate suction, sucks in mosquitoes and traps them in a mosquito storage box, so that they are naturally dehydrated, dried and die. Since the above mosquito killing device needs to use a fan to suck mosquitoes, it will generate a lot of noise and is not suitable for a quiet environment; in addition, the opening size used to suck mosquitoes in the above mosquito killing device is generally small, resulting in low suction efficiency, thus affecting the mosquito killing effect of the device; further, the user needs to clean the mosquito storage box in time, otherwise the mosquitoes that are not dead may escape.

[0005] The second largest category is electric shock-based mosquito killing devices, which generally kill mosquitoes through high-voltage power grids. During the use of the above-mentioned mosquito killing devices, electric shock noise and sparks will be generated, affecting the user experience and safety, especially when children or pets accidentally touch the power grid, which may cause fright or even injury; moreover, dead mosquitoes after electric shock will remain on the power grid of the device, and the dead mosquitoes on the power grid need to be cleaned regularly, which is more troublesome to maintain; in addition, in order to ensure the mosquito killing effect, the electric shock mosquito killing devices used in existing public places are generally large in size, occupying most of the space in the environment, and the aesthetics are very limited.

[0006] In order to overcome the defects of existing mosquito-killing devices on the market, some manufacturers have developed laser-based mosquito-killing devices, which destroy the wing structure or DNA of mosquitoes by emitting laser beams in the environment, causing them to be unable to fly or die, thereby achieving the purpose of killing mosquitoes. However, existing laser-based mosquito-killing devices generally use complex identification systems or detection methods to accurately locate and identify mosquitoes, resulting in complex structures, high manufacturing costs and low reliability of mosquito-killing devices. In particular, the detection method for detecting and locating mosquitoes in three-dimensional space has a large scanning range, and ordinary laser radars are difficult to accurately identify the specific location of flying mosquitoes due to their slow scanning speed; even if a high-frequency laser with an extremely high scanning speed is used, it is difficult to achieve accurate and rapid positioning with existing laser technology. Even if it is achieved, the cost will be extremely high, making it difficult for ordinary consumers to purchase and use it. Summary of the invention

DETAILED DESCRIPTION

[0041] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0042] The technical solution provides a circular scanning laser mosquito killing device, comprising a laser emitting mechanism 2, a circular reflecting surface 102, a light guide 3 and a photoelectric sensor 4 arranged in sequence along the optical path;

[0043] The laser emitting mechanism 2 is disposed inside the annular reflecting surface 102, and the laser emitting mechanism 2 is used to circumferentially emit a laser beam 211 toward the annular reflecting surface 102;

[0044] The annular reflective surface 102 is used to reflect the laser beam 211 to the light guide 3;

[0045] The light guide 3 is used to transmit the laser beam 211 from the annular reflection surface 102 to the photoelectric sensor 4;

[0046] The photoelectric sensor 4 is used to detect the light emitted from the light guide 3 , and the photoelectric sensor 4 is electrically connected to the laser emitting mechanism 2 .

[0047] In order to achieve simple and efficient mosquito killing, this technical solution proposes a circular scanning laser mosquito killing device, such as Figure 1-8 As shown, it includes a laser emitting mechanism 2 for emitting a laser beam 211 in an annular direction toward the annular reflecting surface 102, the annular reflecting surface 102, a light guide 3 for receiving light from the annular reflecting surface 102 for detection by a photoelectric sensor 4, and a photoelectric sensor 4 for detecting light emitted from the light guide 3, and the laser beam 211 emitted from the laser emitting mechanism 2 propagates along the annular reflecting surface 102, the light guide 3 and the photoelectric sensor 4 in sequence.

[0048] The working principle of the laser mosquito killing device of this scheme is as follows: after the device is started, the laser emitting mechanism 2 emits a laser beam 211 toward the annular reflection surface 102, and scans in a circular direction along the extension direction of the annular reflection surface 102, thereby forming a scanning surface (including a scanning plane or a scanning curved surface) between the laser emitting mechanism 2 and the annular reflection surface 102. The optical path diagram of the laser beam 211 is as follows: Figure 2 , 4 and 6. When a mosquito passes through the scanning surface, it will cause the signal of the laser beam 211 to change. After the signal change is captured by the photoelectric sensor 4, it will be transmitted to the laser emitting mechanism 2 electrically connected thereto. At this time, the laser emitting mechanism 2 switches the laser output parameter of the laser beam 211 from the "detection state" to the "killing state" to kill the mosquito. That is, the laser mosquito killing device proposed in this scheme uses the laser beam 211 to form a scanning surface, and detects and kills mosquitoes at the same time, realizing simple and efficient mosquito killing. The device has a simple structure, quiet operation, and reliable performance, which is conducive to improving the mosquito killing effect of the laser mosquito killing device and satisfying the user experience.

[0049] Specifically, the light guide 3 of the present solution can realize the directional conduction of light from the annular reflective surface 102 to the photoelectric sensor 4, so that the photoelectric sensor 4 can conveniently and timely detect the signal change of the laser beam 211 in the scanning surface. Since the photoelectric sensor 4 of the present case is electrically connected (such as wire connection or wireless connection, etc.) to the laser emitting mechanism 2, when the photoelectric sensor 4 detects that the signal of the laser beam 211 has changed, the laser emitting mechanism 2 can immediately adjust the laser output parameters (such as power, etc.) of the laser beam 211 to destroy the wing structure or DNA of the mosquito, thereby quickly responding to the photoelectric sensor 4 and realizing the efficient killing of the mosquito killing device. In addition, since the structural composition of the present solution is simple, the manufacturing cost of the laser mosquito killing device can be greatly reduced, which is more conducive to being purchased and used by general consumers; and the structure is compact, even if the outer diameter of the annular reflective surface 102 is enlarged to increase the probability of catching mosquitoes, thereby increasing the area of ​​the scanning surface, the space occupied by its volume is still small, and it can be conveniently hung on a building structure such as a wall, which can not only reduce the space occupied, but also improve the aesthetics.

[0050] It should be noted that, in a specific embodiment, the laser emitting mechanism 2 of the present solution can rotate around its own axis, thereby forming a scanning surface by circumferential scanning along the extension direction of the annular reflection surface 102, which is not limited here. In addition, the annular reflection surface 102 of the present solution can reflect the laser beam 211 to the light guide 3, and the above-mentioned reflection process can be any one or more combinations of mirror reflection or diffuse reflection, and is selected according to actual needs. And when the reflection process is mirror reflection, the annular reflection surface 102 is a smooth surface; when the reflection process is diffuse reflection, the annular reflection surface 102 is a rough surface.

[0051] Further, the light guide member 3 is a light guide ring. It should be noted that the light guide ring of the present solution can be arranged concentrically or eccentrically with the annular reflective surface 102, which is not limited here.

[0052] Preferably, the light guide ring is concentric with the annular reflective surface 102. In this solution, the light guide 3 is preferably an annular structure concentric with the annular reflective surface 102. When the laser emitting mechanism 2 scans in an annular direction along the extension direction of the annular reflective surface 102, it can ensure that the light reflected by the annular reflective surface 102 can always be received by the light guide 3, so as to ensure the effectiveness and real-time performance of the detection process of the photoelectric sensor 4.

[0053] To further illustrate, the light guide ring is disposed close to the annular reflective surface 102;

[0054] The light guide ring is provided with a detection notch 301 , and the photoelectric sensor 4 is disposed close to the detection notch 301 . The photoelectric sensor 4 is used to detect light emitted from the detection notch 301 .

[0055] In a preferred embodiment of the present technical solution, the light guide 3 is an annular structure arranged close to the annular reflective surface 102. At this time, the light guide 3 is essentially an optical fiber, and the material may be plexiglass, quartz, etc. The cross-sectional shape of the light guide ring may be circular, elliptical, rectangular, triangular, etc., which can be selected according to actual application requirements and is not limited in this case.

[0056] When the light guide ring of the present solution receives the laser beam 211 emitted by the laser emitting mechanism 2, the laser beam 211 will enter the light guide ring through reflection from the annular reflection surface 102, and will be transmitted along the total reflection path inside the light guide ring based on the total reflection principle of light; when the laser beam 211 is transmitted inside the light guide ring and passes through the detection gap 301, part of the light will be emitted from the detection gap 301 and enter the detection end of the photoelectric sensor 4, and thus be detected by the photoelectric sensor 4. In a specific embodiment, during the circumferential scanning process of the laser beam 211, if the laser beam 211 is not blocked by the detection object (i.e., mosquito), the level output of the photoelectric sensor 4 is a stable value; and when the laser beam 211 is blocked, the level output of the photoelectric sensor 4 will change.

[0057] It should be noted that the parameters such as the opening angle and spacing of the detection notch 301 in this solution can be adjusted according to the material or cross-sectional shape of the light guide 3, the end surface area or sensitivity of the detection end of the photoelectric sensor 4, etc., and are not limited here. In this solution, multiple photoelectric sensors 4 can be provided to improve the detection accuracy of the mosquito killing device; in addition, the number and distribution position of the photoelectric sensors 4 can be considered according to the overall size of the mosquito killing device, the transmission speed and attenuation of the laser beam 211 in the light guide ring, the manufacturing cost and other factors, and are not limited here.

[0058] As a specific embodiment of the above scheme, Figure 2-3 As shown, the light guide 3 can be arranged on the inner side of the annular reflective surface 102, and the annular reflective surface 102 can be preferably a rough surface, and the photoelectric sensor 4 is located at the rear end of the detection notch 301. When the laser emitting mechanism 2 emits a laser beam 211 toward the axis of the light guide 3, the laser beam 211 will directly pass through the light guide 3 and act on the annular reflective surface 102, and then diffusely reflect under the action of the annular reflective surface 102 and re-enter the light guide 3, and be conducted inside the light guide 3 along the path of total reflection.

[0059] As another specific embodiment of the above scheme, Figure 4-5As shown, the light guide 3 can be arranged at the outer front end of the annular reflective surface 102, and the annular reflective surface 102 can be preferably a smooth surface, and the photoelectric sensor 4 is located outside the detection notch 301. When the laser emitting mechanism 2 emits the laser beam 211 to the annular reflective surface 102, it will enter the light guide 3 under the mirror reflection of the annular reflective surface 102, and be conducted along the total reflection path inside the light guide 3. Since the light guide 3 is arranged at the outer front end of the annular reflective surface 102, the scanning surface formed by the circumferential scanning of the laser beam 211 can be effectively increased, not only forming a scanning surface between the laser emitting mechanism 2 and the annular reflective surface 102, but also forming another scanning surface between the annular reflective surface 102 and the light guide 3, and when the mosquito passes through the above two scanning surfaces, it can be detected by the photoelectric sensor 4, thereby effectively improving the mosquito killing effect of the laser mosquito killing device. More preferably, this scheme can also add multiple annular reflective surfaces 102 on the basis of this embodiment to further increase the effective area of ​​the scanning surface formed by the circumferential scanning of the laser beam 211.

[0060] To further explain, the light-guiding ring is arranged close to the laser emitting mechanism 2 .

[0061] In another preferred embodiment of the present technical solution, the light guide 3 is an annular structure arranged close to the laser emitting mechanism 2. At this time, the light entering the light guide 3 after being reflected by the annular reflective surface 102 actually exhibits a light scattering phenomenon, so that the detection end of the photoelectric sensor 4 can detect the scattered light emitted from the light guide 3. It should be noted that the material of the light guide 3 that causes the incident light to scatter light can be organic glass, quartz, etc., and the interior thereof can be provided with a frosted surface, a granular surface or an irregular hole structure according to requirements to ensure the occurrence of the scattering phenomenon, which is not limited in this case.

[0062] As a specific embodiment of the above scheme, Figure 6-8 As shown, the light guide 3 can be mounted on the outside of the laser emitting mechanism 2, and the annular reflective surface 102 can be preferably a smooth surface, and the photoelectric sensor 4 is located at the rear end of the detection notch 301. When the laser emitting mechanism 2 emits a laser beam 211 toward the annular reflective surface 102, it enters the light guide 3 under the mirror reflection of the annular reflective surface 102, and is conducted along the total reflection path inside the light guide 3. Since the light guide 3 is mounted on the outside of the laser emitting mechanism 2, when the laser beam 211 is scanned in an annular direction, a double-layer scanning surface can be formed between the laser emitting mechanism 2 and the annular reflective surface 102, so as to further enhance the detection and mosquito killing effect of the laser mosquito killing device.

[0063] It is further explained that the light guide 3 is a light guide block, and the light guide block is located at the axis of the laser emitting mechanism 2, and can be specifically installed protrudingly at the front end or rear end of the laser emitting mechanism 2, which is not limited here. The preferred position can ensure that during the circumferential scanning of the laser emitting mechanism 2, the light guide block can always receive the light reflected from the annular reflection surface 102, so as to ensure the effectiveness and real-time performance of the detection process of the photoelectric sensor 4. It should be noted that the light entering the light guide block after being reflected by the annular reflection surface 102 actually exhibits the same light scattering phenomenon, so that the detection end of the photoelectric sensor 4 can detect the scattered light emitted from the light guide block.

[0064] Further explanation, it also includes a detection disk 1;

[0065] The detection disk 1 is provided with a detection surface 101 , the laser emitting mechanism 2 is installed in the middle of the detection disk 1 , the annular reflection surface 102 is installed at the edge of the detection disk 1 , and the output end of the laser emitting mechanism 2 and the annular reflection surface 102 both protrude from the detection surface 101 .

[0066] Furthermore, in order to improve the probability of catching mosquitoes by the laser mosquito killing device of this scheme, this scheme also provides a detection surface 101 for mosquitoes to stay in the laser mosquito killing device, thereby reducing the emission parameters of the laser emitting mechanism 2 while improving the mosquito killing effect, so as to reduce the manufacturing cost of the mosquito killing device.

[0067] As a preferred embodiment of the above embodiment, the circumferential scanning speed of the laser beam 211 is 1 to 10 r / s. Due to the provision of the detection surface 101, this solution can effectively reduce the emission parameters of the laser emission mechanism 2, so as to reduce the manufacturing cost of the mosquito killing device. However, since the speed of mosquitoes in flight is as high as 1 m / s, in order to quickly detect and effectively kill mosquitoes staying on the detection surface 101, so as to improve the mosquito killing effect of the laser mosquito killing device, this solution can also optimize the circumferential scanning speed of the laser beam 211. It should be noted that the above circumferential scanning speed can allow the laser beam 211 to have a certain action time in the process of killing mosquitoes, so as to ensure sufficient damage to the wing structure or DNA of the mosquito, thereby ensuring the mosquito killing effect of the laser beam 211.

[0068] It should be noted that the annular reflective surface 102 of the present solution can be integrally formed on the edge of the detection disk 1, which is more conducive to simplifying the structural design of the laser mosquito killing device.

[0069] To further illustrate, the distance between the laser beam 211 and the detection surface 101 is 2-10 mm.

[0070] In a specific embodiment of the present technical solution, the distance between the laser beam 211 and the detection surface 101 is optimized according to the body shape of the mosquito, so as to improve the detection effectiveness of the laser beam 211.

[0071] Preferably, the laser beam 211 forms a detection angle with the detection surface 101, and the detection angle is ≤5°.

[0072] In another specific embodiment of the present technical solution, the detection angle formed between the laser beam 211 and the detection surface 101 is optimized according to the reception effectiveness of the light guide 3 and the body size of the mosquito, so as to increase the detection signal strength of the photoelectric sensor 4 and further improve the detection effectiveness of the laser beam 211.

[0073] More preferably, the laser beam 211 and the detection surface 101 are parallel to each other.

[0074] As a better solution of the above embodiment, this solution makes the laser beam 211 and the detection surface 101 parallel to each other, which can further reduce the thickness of the detection plate 1 and further reduce the occupied space of the laser mosquito killing device.

[0075] To further explain, it also includes an anti-escape component, which is arranged on the outside of the light guide 3 and is used to prevent the light entering the light guide 3 from escaping.

[0076] In addition, in order to prevent the light entering the light guide 3 from escaping again, the present solution also adds an anti-escaping component on the outside of the light guide 3 to prevent the light entering the light guide 3 from escaping, so as to further increase the detection signal strength of the photoelectric sensor 4 and further improve the detection effectiveness of the laser beam 211.

[0077] In this program Figure 2-3 In the specific embodiments of 4-5, the anti-escape component of this scheme is an annular cover 5, which is covered on the top of the light guide 3, and a gap 103 is left between the annular cover 5 and the detection disk 1 for avoiding the incidence of the laser beam 211.

[0078] Furthermore, in order to achieve stable installation of the light guide 3 on the edge of the detection disk 1, the present solution further adds an annular cover 5 on the top thereof, and leaves an incident gap 103 for the laser beam 211 to pass through between the annular cover 5 and the detection disk 1, so as to ensure that the light guide 3 effectively receives the laser beam 211. In addition, the provision of the annular cover 5 not only achieves stable installation of the light guide 3, but also helps prevent the light entering the light guide 3 from escaping again, so as to further avoid weakening of the detection signal and prevent the decline of the mosquito killing effect.

[0079] Preferably, the outer side of the annular cover 5 is connected to the outer side of the detection disk 1, and the detection disk 1 and the annular cover 5 together form an accommodating cavity for accommodating the light guide 3. As a preferred solution of the above embodiment, the outer side of the annular cover 5 is connected to the outer side of the detection disk 1, which is conducive to preventing light from escaping from the connection between the annular cover 5 and the detection disk 1.

[0080] Preferably, the shape of the accommodating cavity matches the cross-sectional shape of the light guide 3. As another preferred solution of the above embodiment, the shape of the accommodating cavity matches the cross-sectional shape of the light guide 3, that is, the shape of the inner wall of the accommodating cavity is the same as the shape of the outer wall of the light guide 3, which is more conducive to the escaped light to re-enter the light guide 3 after being reflected by the inner wall of the empty cavity, thereby preventing the weakening of the detection signal.

[0081] More preferably, the inner wall of the accommodating cavity is a rough surface, so that the escaping light can re-enter the light guide 3 under the diffuse reflection effect of the inner wall of the empty cavity, thereby preventing the weakening of the detection signal.

[0082] In this program Figure 6-8 In a specific embodiment, the anti-escape component of the present solution is an anti-escape coating (not shown in the figure), and the anti-escape coating is formed by spraying the anti-escape coating on the front end surface of the light guide 3 and then curing it.

[0083] Compared with the structural anti-escape solution, the anti-escape coating can directly omit the air layer between the light guide 3 and the structural anti-escape, so that the light entering the light guide 3 can only be transmitted inside it, which is more conducive to preventing the weakening of the detection signal. It should be noted that the anti-escape coating can be paint, mirror paint, etc.

[0084] Further, the laser emitting mechanism 2 includes a laser emitter 21 and a reflector 22, wherein the laser emitter 21 is disposed inside the detection plate 1, and the reflector 22 is rotatably mounted outside the detection plate 1;

[0085] The laser emitter 21 is used to emit the laser beam 211 , and the reflector 22 is used to reflect the laser beam 211 emitted by the laser emitter 21 to the light guide 3 .

[0086] Specifically, the laser emitting mechanism 2 of the present solution includes a laser emitter 21 and a reflector 22. After the laser emitter 21 emits a laser beam 211 toward the reflector 22, the circumferential scanning of the laser beam 211 is achieved by rotating the reflector 22. Figure 8 As shown, on the one hand, it can effectively reduce the number of structural parts for realizing the rotation setting, making the structural design simpler, and on the other hand, it can also effectively reduce the maintenance frequency of the mosquito killing device, minimize unnecessary structural wear, and extend the service life of the relevant rotating mechanism and the laser emitter 21.

[0087] It should be noted that when the present solution uses the reflector 22 to change the optical path of the emitted light of the laser beam 211, the laser beam 211 in the above embodiments of "the distance between the laser beam 211 and the detection surface 101" and "the detection angle formed by the laser beam 211 and the detection surface 101" specifically refers to the incident light when the laser beam 211 enters the annular reflection surface 102. The laser emitter 21 of the present solution can be a laser diode, which is low in cost and is more conducive to reducing the manufacturing cost of the laser mosquito killing device.

[0088] Further, the laser emitting mechanism 2 further comprises a rotating assembly 23, and the rotating assembly 23 is rotatably mounted on the middle part of the detection disk 1;

[0089] A light-guiding channel 231 is provided inside the rotating assembly 23, and the entrance of the light-guiding channel 231 is located inside the detection plate 1 and faces the emission end of the laser emitter 21, and the exit of the light-guiding channel 231 protrudes from the detection surface 101;

[0090] The reflector 22 is installed inside the light guiding channel 231 .

[0091] As a preferred embodiment of the above embodiment, the reflector 22 is rotatably installed in the middle of the detection disk 1 through the rotating assembly 23, and the laser beam 211 first completes the optical path change inside the light guide channel 231 and then is emitted to the light guide 3, which can reduce the energy attenuation of the laser beam 211 during the reflection process to a certain extent.

[0092] It should be noted that the rotating assembly 23 of the present solution can be any one or more combinations of conventional rotating structural parts such as a rotating shaft and a rotating disk, and is not limited here.

[0093] Preferably, the laser emitting mechanism 2 further includes a focusing mirror 24 , which is disposed inside the light guiding channel 231 , and the focusing mirror 24 is located between the laser emitter 21 and the reflecting mirror 22 .

[0094] In addition, the present solution may also add a focusing mirror 24 inside the light guide channel 231 to increase the intensity of the laser light emitted by the laser emitter 21 to enhance the detection and killing signals, or adjust the spot size of the laser light to improve the accuracy of the laser beam 211.

[0095] Further description, it also includes a mosquito attracting mechanism.

[0096] Specifically, the mosquito attracting mechanism of the present invention comprises any one or more combinations of a carbon dioxide generator 6, a light emitter 7 and a heater 8, such as Figure 6 shown.

[0097] Preferably, the mosquito attracting mechanism is a carbon dioxide generator 6 , the detection surface 101 is provided with an air source inlet 1011 , and the output end of the carbon dioxide generator 6 is connected to the air source inlet 1011 .

[0098] According to relevant research, mosquitoes are attracted by being sensitive to certain specific factors of humans and other animals. Specifically, mosquitoes can detect carbon dioxide exhaled by humans and other animals, which is an important clue for them to locate hosts.

[0099] Therefore, in order to enable the laser mosquito killing device of this scheme to lure mosquitoes to stay on the detection surface 101, this scheme also adds a carbon dioxide generator 6 in the device, so that the carbon dioxide gas generated by the carbon dioxide generator 6 is gathered on the detection surface 101 through the gas source inlet 1011 to enhance the mosquito killing effect of the laser mosquito killing device.

[0100] In a specific embodiment, in order to reduce the manufacturing cost of the device, the carbon dioxide generator 6 used in this scheme is preferably a box structure that can hold carbon dioxide sustained-release tablets, and the outlet of the above-mentioned box structure is connected to the gas source inlet 1011 through an air pipe, which can reduce costs while ensuring the effective transportation of carbon dioxide gas.

[0101] In another specific embodiment, the gas source inlet 1011 of the present solution is located at the upper part of the detection surface 101 so that the carbon dioxide gas naturally moves downward due to its greater density (compared with air), thereby facilitating its uniform distribution on the detection surface 101.

[0102] Preferably, the mosquito attracting mechanism is a light emitter 7.

[0103] In addition, mosquitoes have a strong tendency to move toward light. Therefore, in order to further enable the laser mosquito killing device of this solution to lure mosquitoes to stay on the detection surface 101, this solution also adds a light emitter 7 to the device to make mosquitoes gather on the detection surface 101.

[0104] It should be noted that the location and number of the light emitters 7 in this solution can be considered based on the mosquito attracting effect and the decorative effect of the mosquito killing device, and are not limited here.

[0105] Preferably, the light emitter 7 of the present solution may be a light emitting diode, which is low in cost and more conducive to reducing the manufacturing cost of the laser mosquito killing device.

[0106] Preferably, the wavelength of the light source of the light emitter 7 is 405-450nm. Mosquitoes are attracted to light sources with specific wavelengths. Therefore, in order to take into account both the mosquito attracting effect and the manufacturing cost of the mosquito killing device, the wavelength of the light source of the light emitter 7 is preferably 405-450nm.

[0107] Preferably, the mosquito attracting mechanism is a heater 8.

[0108] In addition, mosquitoes are thermotropic and are attracted by human body temperature. Therefore, the laser mosquito killing device of this solution can also be equipped with a heater 8 near the detection surface 101 to simulate human body temperature to attract mosquitoes.

[0109] It should be noted that the location and number of the heater 8 in this solution can be considered based on the mosquito attracting effect and the manufacturing cost of the mosquito killing device, and are not limited here. In a specific embodiment, the heater 8 of this solution is attached to the back side of the detection plate 1 opposite to the detection surface 101.

[0110] Preferably, the heater 8 of the present solution may be a heating element such as a heating tube or a heating plate, which is low in cost and more conducive to reducing the manufacturing cost of the laser mosquito killing device.

[0111] Preferably, the annular scanning laser mosquito killing device of the present solution further includes an alarm 9 , and the alarm 9 is arranged close to the detection surface 101 .

[0112] In a more preferred embodiment of the present technical solution, in order to prevent the laser beam 211 from causing harm to human body or pets, the present solution also adds an alarm 9 for safety protection in the mosquito killing device. Specifically, the alarm 9 can be an infrared detector, a PIR sensor, etc., which is not limited here.

[0113] Preferably, the annular scanning laser mosquito killing device of the present solution further includes a mosquito receiving groove, and the mosquito receiving groove is protrudingly arranged at the bottom of the detection surface 101.

[0114] This helps prevent mosquitoes from falling on the ground in the space at will and keeps the environment clean. At the same time, users can also clean the mosquito killing device conveniently and quickly.
