Description

Technical Field

[0001] This invention belongs to the field of specimen collection technology for mosquito research, and particularly relates to a non-destructive specimen collector for mosquitoes. Background Technology

[0002] Mosquitoes belong to the family Culicidae in the order Diptera, and most are small, long-legged, two-winged insects. Their bodies are divided into three parts: head, thorax, and abdomen. The head has a pair of compound eyes and a pair of antennae; the compound eyes are well-developed, the antennae have whorled hairs, and the proboscis is relatively long, serving as a piercing-sucking mouthpart. The thorax is divided into prothorax, mesothorax, and metathorax, each segment having a pair of legs, namely forelegs, mesothorax, and hindlegs. The mesothorax also has a pair of wings, which are narrow, membranous, and brown or black. The metathorax has a pair of halteres evolved from the hindwings. Both the mesothorax and metathorax have a pair of spiracles. The legs are slender, and the scales on the legs, such as white rings, white spots, and longitudinal lines, are one of the distinguishing features of mosquito species. The body is covered with scales and fine hairs. The main mosquito species found in human habitats include Culex pipiens pallens, Aedes albopictus, Anopheles sinensis, Aedes tumefaciens, and Culex tritaeniorhynchus. In daily life, mosquito infestations cause many problems for people. Mosquitoes not only bite humans, causing itchy and swollen skin, but they can also transmit various diseases such as dengue fever, chikungunya, and malaria, seriously threatening human health. Mosquito specimens are fundamental to research on the harm mosquitoes cause to humans; therefore, the development of mosquito collection devices is crucial. However, most existing collection devices are traps, and mosquitoes are often damaged by fan blades during the trapping process, resulting in damage to their scales and affecting subsequent classification, identification, and other related research. Summary of the Invention

[0003] The purpose of this invention is to provide a non-destructive specimen collector for mosquitoes. This invention optimizes the airflow path of the fan, with the mosquito inlet being a narrow annular groove through which the airflow velocity is relatively high. After entering the cavity, the space becomes larger and the airflow velocity decreases. The mosquitoes enter the mosquito collection box under the superposition of inertia and vortex. Throughout the process, since the mosquitoes do not directly contact the fan blades, live mosquitoes can be obtained intact for subsequent research.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A non-destructive mosquito specimen collector includes a top cover, an upper shell connected to the top cover, a lower shell connected to the upper shell, and a mosquito collection box located at the bottom of the lower shell and movably connected thereto. A power supply, a fan, and a light-transmitting cover are disposed within the cavity between the top cover and the upper shell. The air inlet of the fan is connected to the lower shell and the mosquito collection box through the light-transmitting cover. The upper shell is a hollow cylindrical cavity with a ring of evenly distributed perforated openings around its lower circumference, serving as the mosquito entrance. A connecting part connected to the light-transmitting cover is located at the center of the bottom of the upper shell, and the connecting part is integrally formed with the upper shell by multiple radial ribs. The design features a mosquito suction port between adjacent ribs. This port uses negative pressure to draw mosquitoes into the cavity between the upper shell and the light-transmitting cover. Because the suction port is a narrow slot, the airflow velocity is relatively high. After entering the cavity, the space becomes larger and the airflow velocity decreases. In addition, the light-transmitting cover further lowers the fan inlet to the lower shell. The mosquitoes then pass through the external space of the lower shell's isolation mesh and enter the mosquito collection box under the superposition of inertia and vortex. The bottom of the upper shell is also provided with slots for LED lights to pass through. The LED lights on the LED light board pass through the slots and are fixedly connected to the bottom of the upper shell.

[0005] Furthermore, it also includes an isolation net located inside the lower housing. The isolation net is fixedly connected to the bottom of the upper housing via an isolation net base plate and an isolation net support column. The isolation net is used to prevent mosquitoes from entering the fan air inlet channel, thus serving both an isolation function and forcing mosquitoes into the mosquito collection box at the bottom.

[0006] Furthermore, the light-transmitting cover is funnel-shaped, wider at the top and narrower at the bottom. The upper part of the light-transmitting cover is engaged with the fan fixing frame. The fan fixing frame has an air outlet around its circumference, which is connected to the outside through a hole on the upper cover. On the one hand, the light-transmitting cover moves the air inlet downward to better form a vortex between the mosquito collection box and the lower shell. On the other hand, the light-transmitting cover can amplify the light generated by the LED light to better attract mosquitoes.

[0007] Furthermore, the LED light is an LED ultraviolet lamp bead or a eutectic LED ultraviolet lamp bead, with the lamp beads installed at an angle towards the light-transmitting cover. A lens is also provided on the surface of the lamp bead to further concentrate the light and better reflect it into the light-transmitting cover to attract mosquitoes. The LED light emits ultraviolet light in the 365-400 nanometer wavelength range. Mosquitoes are attracted to ultraviolet light, especially violet or ultraviolet light with wavelengths in the 365-400 nanometer range. This is mainly because the violetin protein in the mosquito's compound eyes is particularly sensitive to this wavelength, converting it into nerve signals that guide them closer to the light source. The mosquitoes are attracted from a distance by the light-transmitting cover and drawn to the mosquito-sucking opening by the LED light.

[0008] Furthermore, the mosquito collection box includes a mosquito collection box fixing frame, a mosquito collection box inlet rotating opening and a box body that are rotatably connected to the mosquito collection box fixing frame. This design allows the mosquito collection box to be directly removed and used as a specimen box, which is convenient and quick.

[0009] Furthermore, the upper part of the mosquito collection box fixing frame is rotatably connected to the lower shell, the lower part of the mosquito collection box fixing frame is rotatably engaged with the box body, and a fixing plate is provided inside the mosquito collection box fixing frame. The fixing plate is evenly provided with multiple first mosquito inlets along the circumference, and a central through hole is provided in the center of the fixing plate. Multiple screw holes are also provided on the fixing plate along the circumference of the central through hole.

[0010] Furthermore, the mosquito inlet rotating opening of the mosquito collection box is a circular plate. Multiple second mosquito inlets, matching the first mosquito inlet, are evenly distributed around the circumference of the rotating opening. A handle is also provided at the center of the rotating opening, with multiple arc-shaped slots along the circumference of the handle corresponding to the screw holes on the fixing plate. The rotating opening and the fixing frame of the mosquito collection box are rotatably fixed together by self-tapping screws passing through the arc-shaped slots and screw holes. The fixing plate of the fixing frame of the mosquito collection box also has an upper locking hole, and the box body has a lower locking hole. The box body and the fixing frame of the mosquito collection box are fixed by a self-locking slider. The self-locking slider is a right-angled plate, including an upper horizontal plate and a vertical side plate. An upper locking platform is provided at the end of the upper horizontal plate, and a lower locking platform is provided on the outer side of the vertical side plate. The upper locking platform is located inside the upper locking hole, which is an elongated slot.

[0011] Furthermore, the top cover has a perforated hole, and a hanging ring is provided at the center of the top of the top cover to facilitate hanging the entire device.

[0012] The advantages of this invention are: 1. In this invention, the air inlet of the fan is moved down to the lower shell through the action of the light-transmitting cover. The mosquito suction port sucks the mosquitoes that have entered the hollow doorway into the cavity between the upper shell and the light-transmitting cover through the negative pressure suction. Since the mosquito suction port is a narrow groove, the airflow velocity is relatively high. After entering the cavity, the space becomes larger and the airflow velocity decreases. In addition, the light-transmitting cover moves the air inlet of the fan further down to the lower shell. The mosquitoes further enter the mosquito collection box through the external space of the lower shell isolation net under the superposition of inertia and vortex. The whole process does not damage the mosquitoes and can obtain complete specimens for subsequent research. 2. In this invention, LED ultraviolet lamp beads or eutectic LED ultraviolet lamp beads are used. The lamp beads are all installed at an angle towards the light-transmitting cover. Lenses are also provided on the surface of the lamp beads to further concentrate the light and better reflect it into the light-transmitting cover to prepare for attracting mosquitoes. Mosquitoes are attracted to ultraviolet light, especially violet or ultraviolet light with wavelengths of 365-400 nanometers. This is mainly because the violetin protein in the compound eyes of mosquitoes is particularly sensitive to this wavelength and can convert it into nerve signals to guide them closer to the light source. Mosquitoes are attracted from a distance by the light-transmitting cover and drawn to the mosquito-absorbing opening by the LED lamp. The setting of evenly dispersing the single bright spot of the LED lamp through the lens avoids the presence of other insects. 3. The mosquito collection box in this invention can control the opening and closing of the first and second mosquito inlets by rotating the handle of the mosquito inlet. When the mosquito trapping is finished, the first and second mosquito inlets can be closed to take the entire mosquito collection box away for use as a specimen box, which is convenient and quick.

[0019] like Figure 1-6As shown, a non-destructive mosquito specimen collector includes an upper cover 2 with perforated holes for fan ventilation and a hanging ring 1 at the top center for easy hanging of the entire device; it also includes an upper shell 14 connected to the upper cover, a lower shell 20 connected to the upper shell, and a mosquito collection box 21 located at the bottom of the lower shell and movably connected thereto; a power supply 5, a fan 12, and a light-transmitting cover 13 are arranged in the cavity between the upper cover and the upper shell; to better fix the power supply, a power supply box shell 6 and a box cover 4 are also provided, with the power supply located inside the power supply box shell, and the power supply box shell 6 and the box cover 4 are fixed by a first self-tapping screw 3; to better control the operation of the device, a control module mounting bracket 8 is provided outside the power supply box shell 6, with a control module 7 inside the control module mounting bracket, and an OLED display screen 9 on the control module; the control module mounting bracket, control module, and OLED display screen are fixedly connected to the power supply box shell by countersunk bolts 10; the control module is powered by the power supply and is used to control the fan and LED beads; to better fix the fan, a fan support column is also provided for fixing the fan. The fan is fixedly installed at the lower part of the power supply box housing; the air inlet of the fan is connected to the lower housing 20 and the mosquito collection box 21 through the light-transmitting cover 13; the upper housing is a hollow cylindrical cavity, and a ring of evenly distributed perforated doorways 22 is provided around the lower circumference of the upper housing, which serves as the entrance for mosquitoes; a connecting part is provided at the center of the bottom of the upper housing, which is connected to the light-transmitting cover; the connecting part and the upper housing are integrally formed with the upper housing through multiple radial ribs, and the space between adjacent ribs is a mosquito suction port, which sucks the mosquitoes that enter the perforated doorways into the space between the upper housing and the light-transmitting cover through negative pressure suction. After the cavity is filled, the airflow velocity is relatively high due to the narrow groove of the mosquito suction port. After entering the cavity, the space becomes larger and the airflow velocity decreases. In addition, the light-transmitting cover moves the air inlet of the fan further down to the lower shell. Under the superposition of inertia and vortex, mosquitoes enter the mosquito collection box through the external space of the lower shell isolation net 18. The bottom of the upper shell is also provided with a slot for LED lights to pass through. After the LED lights on the LED light board 16 pass through the slot, they are fixedly connected to the bottom of the upper shell. For aesthetic purposes, the upper shell is also provided with a fixing frame and an external panel 15 for fixing the control module.

[0020] Furthermore, it also includes an isolation net located inside the lower housing. The isolation net is fixedly connected to the bottom of the upper housing via an isolation net base plate 19 and an isolation net support column 17. The isolation net is used to prevent mosquitoes from entering the fan air inlet channel, thus serving both an isolation function and forcing mosquitoes into the mosquito collection box at the bottom.

[0021] Furthermore, the light-transmitting cover is funnel-shaped, wider at the top and narrower at the bottom. The upper part of the light-transmitting cover is engaged with the fan fixing frame. The fan fixing frame has an air outlet around its circumference, which is connected to the outside through a hole on the upper cover. On the one hand, the light-transmitting cover moves the air inlet downward to better form a vortex between the mosquito collection box and the lower shell. On the other hand, the light-transmitting cover can amplify the light generated by the LED light to better attract mosquitoes.

[0022] Furthermore, the LED light is an LED ultraviolet lamp bead or a eutectic LED ultraviolet lamp bead, with the lamp beads installed at an angle towards the light-transmitting cover. A lens is also provided on the surface of the lamp bead to further concentrate the light and better reflect it into the light-transmitting cover to attract mosquitoes. The LED light emits ultraviolet light in the 365-400 nanometer wavelength range. Mosquitoes are attracted to ultraviolet light, especially violet or ultraviolet light with wavelengths in the 365-400 nanometer range. This is mainly because the violetin protein in the mosquito's compound eyes is particularly sensitive to this wavelength, converting it into nerve signals that guide them closer to the light source. The mosquitoes are attracted from a distance by the light-transmitting cover and drawn to the mosquito-sucking opening by the LED light.

[0023] Furthermore, the mosquito collection box 21 includes a mosquito collection box fixing frame 211, a mosquito collection box inlet rotating opening 212 and a box body 213 rotatably connected to the mosquito collection box fixing frame. This configuration allows the mosquito collection box to be directly removed and used as a specimen box, which is convenient and quick. The upper part of the mosquito collection box fixing frame is rotatably connected to the lower shell, and the lower part of the mosquito collection box fixing frame is rotatably engaged with the box body. A fixing plate 2111 is provided inside the mosquito collection box fixing frame. The fixing plate has a plurality of first mosquito inlets 2112 evenly distributed around its circumference. A central through hole is provided in the center of the fixing plate, and a plurality of screw holes are also provided around the circumference of the central through hole on the fixing plate. The mosquito collection box inlet rotating opening is a circular plate shape. A plurality of second mosquito inlets 2121 matching the first mosquito inlets are evenly distributed around the circumference of the mosquito collection box inlet rotating opening, and a hand is also provided in the center of the mosquito collection box inlet rotating opening. The handle 2122 has multiple arc-shaped slots 2123 along its circumference that are opposite to the screw holes of the fixing plate. The mosquito collection box inlet and the mosquito collection box fixing frame are rotatably fixedly connected by self-tapping screws passing through the arc-shaped slots and screw holes. This arrangement allows the mosquito collection box fixing frame and the mosquito collection box inlet to rotate relative to each other within the length of the arc-shaped slots to control the opening and closing of the first and second mosquito inlets. The fixing plate of the mosquito collection box fixing frame is also provided with an upper locking hole 2113, and the box body is provided with a lower locking hole 2131. The box body and the mosquito collection box fixing frame are fixed by a self-locking slider 214. The self-locking slider is a right-angled plate, including an upper horizontal plate and a vertical side plate. The upper horizontal plate has an upper locking platform 2141 at its end, and the lower locking platform 2142 is provided on the outer side of the vertical side plate. The upper locking platform is located in the upper locking hole, which is an elongated slot.

[0024] In practical use, the entire device is hung in an area where mosquitoes are concentrated and active. The control module switch is turned on, activating the fan and LED lights. Mosquitoes are attracted to the light-transmitting cover by the light and, due to negative pressure suction, enter the perforated doorway and mosquito-absorbing port. They are then further sucked into the cavity between the upper shell and the light-transmitting cover. Because the mosquito-absorbing port is a narrow slot, the airflow velocity is relatively high. After entering the cavity, the space becomes larger, and the airflow velocity decreases. In addition, the light-transmitting cover moves the fan's air inlet further down to the lower shell. Under the superposition of inertia and vortex, the mosquitoes pass through the external space of the lower shell's isolation net and enter the mosquito collection box. When specimens are needed, the power switch is turned off, the mosquito collection box is removed, and the handle is rotated to close the first and second mosquito-absorbing ports. When the captured specimens are needed, the upper locking platform is engaged, causing the lower locking platform of the self-locking slider to disengage from the lower locking hole, thus separating the box and the mosquito collection box fixing frame. The whole process is convenient and quick, and the obtained live specimen tissues are not damaged, facilitating research.
