Description

Technical Field

[0001] The invention relates to the field of mosquito killing. Background Art

[0002] The harm caused by mosquitoes is well known. Mosquitoes can spread more than 80 infectious diseases such as dengue fever, malaria, Japanese encephalitis, filariasis, etc., and have become a serious global environmental and public health problem.

[0003] From publicly released research data, we know that in the long process of evolution, mosquitoes have evolved to detect humans through the smell of substances such as carbon dioxide in human breath, lactic acid, urea and amino acids in sweat, determine the specific direction, and then accurately find the target of blood sucking. Research has found that for humans, mosquitoes can sense the carbon dioxide and special smell exhaled by humans at a distance of 60 meters.

[0004] In recent years, many products have appeared on the market that use bionic technology to release carbon dioxide and artificial sweat to attract mosquitoes, and kill them with fans or electric shocks. After these products were put on the market, they have played a relatively good effect in indoors, courtyards, sports fields, and parks, and have been widely used. The current products mainly simulate the release of carbon dioxide and artificial sweat by humans, and some also provide carbon dioxide and heat by burning gas, liquefied gas, etc. to increase the equipment's ability to attract mosquitoes. However, in fact, these areas where the equipment is deployed can indeed attract mosquitoes in the surrounding area and kill most of them. The best results can reach a killing rate of 90%, but the remaining 10% is still very harmful to humans.

[0005] Research has found that about 10% of mosquitoes will slip through the net because, after mosquitoes locate people through carbon dioxide and odor and fly near people, the first stage of direction positioning is achieved for mosquitoes, and they find the object to suck blood. For devices that simulate the smell of people, the first stage of attracting mosquitoes to the vicinity of the device is achieved. In the natural state, mosquitoes need to make the second stage of judgment after flying near people, which is where to suck blood. At this time, mosquitoes are no longer just located by carbon dioxide. Mosquitoes have well-developed senses of smell and touch. They can judge by infrared radiation generated by temperature, odor, and slight vibrations of blood flow. After accurately finding the blood vessels, they insert the straw into the blood vessels to suck blood. Summary of the invention

[0006] The object of the present invention is: a blood simulation unit, which is used in a bionic mosquito killer, comprises:

[0007] A bionic integrated block base, which fixes each component;

[0008] A blood flow simulation tube passes through the bionic integrated block base, and the blood flow simulation tube has a blood flow simulation tube inlet and a blood flow simulation tube outlet;

[0009] Body temperature simulation electric heating block, which has a temperature similar to that of the human body surface, can simulate human skin, and emit infrared radiation with a wavelength close to that of the human body;

[0010] The peristaltic unit is respectively connected with the inlet and the outlet of the blood flow simulation tube so as to provide a pulse liquid flow simulating blood flow into the blood flow simulation tube.

[0011] In a preferred embodiment, the peristaltic unit comprises:

[0012] The simulated peristaltic pump inlet tube, simulated peristaltic pump liquid tank, simulated peristaltic pump, and simulated peristaltic pump outlet tube are connected in sequence; the simulated peristaltic pump liquid tank and the simulated peristaltic pump are connected through a pipeline; the simulated peristaltic pump inlet tube is connected to the outlet of the blood flow simulation tube; the simulated peristaltic pump outlet tube is connected to the inlet of the blood flow simulation tube; when the simulated peristaltic pump is peristaltic, it can provide a pulsed liquid flow simulating human blood to the blood flow simulation tube.

[0013] The present application also discloses a bionic mosquito killer, comprising the blood simulation unit, which also includes:

[0014] A housing, wherein a cavity is formed inside the housing; the housing surface has at least one suction and ejection port; and the blood flow simulation tube is located in the suction and ejection port;

[0015] A mosquito collecting net bag, which is located in the cavity;

[0016] The mosquito suction fan is located between the mosquito collection net bag and the mosquito suction and ejection port, and can suck the mosquitoes at the mosquito suction and ejection port into the mosquito collection net bag; an anti-escape one-way valve is provided between the mosquito suction fan and the mosquito collection net bag. A bag taking window is provided on the surface of the housing, which can take out the mosquito collection net bag.

[0017] The bionic mosquito killer also includes a breathing simulation unit which simulates human breathing.

[0018] In a preferred embodiment, the breathing simulation unit includes an artificial sweat container, the artificial sweat container is connected to an evaporation rod, the evaporation rod is connected to a mixing chamber, the mixing chamber is connected to a gas cylinder through a pipeline provided with a solenoid valve, the gas cylinder is located to store carbon dioxide, and the mixing chamber is also connected to a simulation fan and a breathing simulation jet gas outlet pipe; the outlet of the breathing simulation jet gas outlet pipe is located in the suction and jet port.

[0019] In the preferred solution, the breathing simulation jet gas delivery outlet pipe passes through the bionic integrated block base. The housing surface is provided with two mosquito suction and jet ports at opposite positions.

[0020] Based on the existing technology, the present application adds vibrations that simulate human breathing, skin temperature, and blood flow at timed intervals, so that mosquitoes can distinguish whether it is an ordinary heat source, a carbon dioxide source, or human breathing. This not only improves the ability to attract mosquitoes remotely, but also further improves the device's ability to trap mosquitoes at close range, thereby improving the efficiency of mosquito catching and killing.

[0021] The present application achieves four effects on the existing bionic technology: First, it simulates the frequency of human breathing and releases the mixed smell of carbon dioxide and artificial sweat in a pulse mode of 16-25 times / minute. Due to the intense thermal motion of the carbon dioxide and artificial sweat particles in the sprayed mixed gas in the air, the propagation speed is very fast. Although they collide with oxygen molecules and nitrogen in the air, a small amount of particles can still be quickly spread to 100 meters away, so that they can be felt by mosquitoes with extremely keen sense of smell. The spraying time should not be too long each time, so as not to affect the suction of mosquitoes. It is best to control it between 1-5 seconds, so that the bionic degree is higher, and the mixed smell felt by mosquitoes is a pulse smell similar to the breathing frequency, which has a stronger attraction to the surrounding mosquitoes and can attract more mosquitoes to the vicinity of the device. Second, it simulates human body temperature and sets a constant temperature block with a temperature of 35-37 degrees Celsius at the spray and suction port, so that mosquitoes can feel the special infrared waves in this temperature range, so that mosquitoes can enter the suction mosquito port more accurately, and avoid mosquitoes losing direction and escaping the net. Third, to simulate the flow of human blood vessels, the thermostat is integrated with a peristaltic pump to form a small liquid (water) flow with a peristaltic frequency of 70 times / minute, close to the blood pulse frequency of the human body. In this way, when mosquitoes approach the device, they can not only find that the temperature and smell are close to those of the human body, but also feel slight vibrations similar to blood flow, which further encourages mosquitoes to approach the simulated blood vessels and increase the possibility of being killed. Fourth, the mosquito suction fan and the mixed odor spray work asynchronously and alternately. When the mixed odor is sprayed, the mosquito suction fan stops working. After the spray is completed, it pauses for about 1 second and then starts working. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0029] This embodiment discloses a blood simulation unit, which is used in a bionic mosquito killer, and includes:

[0030] The bionic integrated block base is used to fix various components and can use existing technology.

[0031] The blood flow simulation tube passes through the bionic integrated block base. The blood flow simulation tube has a blood flow simulation tube inlet 5 and a blood flow simulation tube outlet 6. The size of the blood flow simulation tube can be set according to needs and can be close to the size of human blood vessels.

[0032] Body temperature simulation electric heating is fast, which is a conventional heater component used to simulate human body temperature. For example, a heating device can be provided in a silicone material to heat the silicone;

[0033] The peristaltic unit 13 is connected to the inlet and outlet of the blood flow simulation tube respectively, so as to provide a pulsed liquid flow simulating blood flow into the blood flow simulation tube. The peristaltic unit comprises:

[0034] The simulated peristaltic pump inlet tube 132, the simulated peristaltic pump liquid tank 131, the simulated peristaltic pump 133, and the simulated peristaltic pump outlet tube 134 are connected in sequence. The simulated peristaltic pump liquid tank 131 and the simulated peristaltic pump 133 are connected through pipelines. The simulated peristaltic pump inlet tube 132 is connected to the outlet of the blood flow simulation tube. The simulated peristaltic pump outlet tube 134 is connected to the inlet of the blood flow simulation tube. When the simulated peristaltic pump 133 is peristaltic, it can provide a pulsed liquid flow simulating human blood to the blood flow simulation tube.

[0035] When in use, the simulated peristaltic pump is controlled by the PLC program control module 15. The simulated peristaltic pump can deliver the simulated blood liquid in the peristaltic pump liquid tank 131 to the inlet of the blood flow simulation tube through the simulated peristaltic pump outlet tube 134, and then pass through the blood flow simulation tube, and then be recovered into the peristaltic pump liquid tank 131 through the blood flow simulation tube outlet and the simulated peristaltic pump inlet tube 132. Then, a pulsed liquid flow similar to blood is formed in the blood flow simulation tube, which can better attract mosquitoes.

[0036] like Figure 1 As shown, the present application discloses a bionic mosquito killer including the above-mentioned blood simulation unit, which also includes: a housing 1, a mosquito collecting net bag 8, and a mosquito suction fan 3.

[0037] A cavity is formed inside the casing 1; the casing surface has at least one suction and ejection port 11; the blood flow simulation tube is located in the suction and ejection port 11, the top of the casing is a top cover 12, and the suction and ejection port 11 is below the top cover 12. Preferably, the casing 1 surface is provided with two suction and ejection ports 11 in opposite positions.

[0038] The mosquito collecting net bag 8 is located in the cavity, and a bag taking window 9 is provided on the surface of the housing 1, through which the mosquito collecting net bag 8 can be taken out.

[0039] The mosquito suction fan 3 is located between the mosquito collection net bag 8 and the mosquito suction and ejection port 11, and can suck the mosquitoes at the mosquito suction and ejection port 11 into the mosquito collection net bag 8. Preferably, a conical frame is provided in the cavity, the mosquito collection net bag 8 is detachably mounted on the end of the conical frame, and the mosquito suction fan 3 is mounted on the conical frame. An anti-escape one-way valve 2 is provided between the mosquito suction fan 3 and the mosquito collection net bag 8, which is a common one-way valve structure.

[0040] In a more preferred solution, the bionic mosquito killer also includes a breathing simulation unit 14 that simulates human breathing, which can be a common breathing simulation unit 14 that can simulate the release of human breathing gas. In a preferred solution, the breathing simulation unit 14 includes an artificial sweat container 141, and the artificial sweat is a mixed emulsion of sodium chloride, urea, lactic acid, fatty acids, amino acids, water, etc. mixed in a certain proportion, and a trace amount of artificial sweat is evaporated into the bionic odor mixing chamber through an artificial sweat evaporation rod. The artificial sweat container 141 is connected to an evaporation rod 142, and the evaporation rod 142 is connected to a mixing chamber 143. The mixing chamber 143 is connected to a gas cylinder 144 through a pipeline provided with an electromagnetic valve 145. The gas cylinder is located to store carbon dioxide. The mixing chamber 143 is also connected to a simulation fan 146 and a breathing simulation jet gas outlet pipe 147; the outlet of the breathing simulation jet gas outlet pipe is located in the mosquito suction and injection port 11. When it is necessary to release the breathing gas, the simulated sweat from the artificial sweat container 141 is mixed with the gas containing carbon dioxide from the evaporation rod 142 and the gas cylinder 144, and is periodically ejected from the breathing simulation jet gas delivery outlet pipe 147 under the action of the simulation fan 146 to attract mosquitoes. In the preferred embodiment, the breathing simulation jet gas delivery outlet pipe 147 passes through the bionic integrated block base 4.

[0041] Part of the components of the peristaltic unit 13 and the breathing simulation unit 14 of the present application are installed in the bionic control box 7, and the bionic control box 7 is connected to the mosquito suction fan 3 through the mosquito suction fan power line 10.

[0042] When the simulated fan 146 of the present application is started, the solenoid valve 145 is opened, and a certain amount of carbon dioxide enters the bionic odor mixing chamber 143, and is mixed with air and artificial sweat evaporation substances, and then sprayed to the mosquito suction and the spray port 11 through the breathing simulation spray tube. The mixed gas is transmitted to a distant place through the thermal motion of the particles. This spray is a pulse spray that simulates human breathing 16-20 times / minute. Mosquitoes in the distance mistakenly think that it is human breathing after sensing it, and fly to the device. The length of each spraying time can be set to 1-5 seconds. The mosquito suction fan stops rotating during spraying. 1-3 seconds after the spraying is completed, the mosquito suction fan restarts, forming a cyclic asynchronous start-up operation with a time interval of 1-3 seconds with the breathing simulation fan.

[0043] Since the concentration of the mixed gas in the device itself is the highest, after the mosquito flies near the device, it will follow the source of the mixed smell to get close to the device. After the mosquito approaches the device through its sense of smell, it further senses the simulated human body temperature of 35-37 degrees Celsius and the simulated blood flow at a frequency of 70 times / minute, allowing the mosquito to more accurately approach the mosquito suction and injection port, and be sucked into the mosquito collection net bag by the mosquito suction fan. The entrance of the mosquito collection net bag has a one-way valve, which is opened by the wind pressure when the mosquito suction fan is started, otherwise it is in a closed state, thereby preventing the mosquito from flying out from the entrance. After the mosquitoes of the present application are sucked into the mosquito collection net bag, they are dried to death by the continuous fan.

[0044] The present application further simulates the intermittent breathing characteristics and blood flow and body temperature characteristics of human beings, and has a higher degree of bionics than the bionic mosquito killing devices currently on the market, and can attract and kill mosquitoes more efficiently, thereby improving the mosquito killing efficiency of a single device. The present invention adopts an asynchronous start-up scheme with intervals between the breathing simulation fan and the mosquito suction fan, so that the mixed gas of carbon dioxide and artificial sweat can spread farther, thereby increasing the working range of a single device, reducing the investment in the equipment, and greatly improving the mosquito killing effect.
