Description

Technical Field

[0001] This utility model relates to the field of blood-sucking insect breeding technology, specifically to a flea breeding device. Background Technology

[0002] Blood-sucking insects, such as ticks, mites, fleas, and lice, are a very important group of medically significant insects. They serve as vectors or reservoirs for various vector-borne diseases, including plague, hemorrhagic fever, leishmaniasis, and Japanese encephalitis. Therefore, understanding, mastering, and conducting in-depth research on these blood-sucking insects is crucial in both the fields of biology and preventive medicine. The reproduction of the life cycle and blood-sucking models of blood-sucking insects is a vital aspect of vector biology and the prevention and control of vector-borne diseases.

[0003] In the initial stage of flea breeding and research, it is necessary to provide fleas with a suitable living space, such as providing a suitable temperature and a sufficient supply of blood, to ensure that enough fleas can be bred for research. Because fleas are small in size and highly active, when taking flea samples, it is necessary to put the fleas in a low-temperature environment (such as ice water or a refrigerator) in advance to reduce their activity so that samples can be taken. During the breeding process, it is difficult to control the breeding temperature and ensure the blood supply, and it is also difficult to control the rapid cooling of fleas in a low-temperature environment.

[0004] Patent CN102812927B discloses a method for using an automatic insect blood feeder, comprising a constant-temperature blood supply body, an insect-collecting funnel, a valve plate, a valve stem, and a locking device. The constant-temperature blood supply body includes a constant-temperature water tank and a constant-temperature plate. The constant-temperature plate is fixed to the bottom of the constant-temperature water tank, and the bottom of the constant-temperature plate has a downward-facing blood groove covered with a biofilm. The constant-temperature plate is sealed in a conical cavity above the insect-collecting funnel. A valve plate, which moves upward to allow insects to enter and exit, is installed inside the insect-collecting funnel below the constant-temperature plate. A collection chamber for insects is formed between the bottom surface of the thermostatic plate and the valve plate. Ventilation holes are distributed on the valve plate. A valve stem is fixedly installed at the bottom of the valve plate, and a valve plug is fixedly installed at the bottom end of the valve stem. A locking device that can lock the valve plug is fixedly installed at the lower end of the insect-collecting funnel corresponding to the valve plug. The upper part of the thermostatic water tank has an inlet pipe and an outlet pipe communicating with the inner cavity of the tank. There is a blood inlet hole on the thermostatic plate at one end of the blood tank, communicating with the blood tank. There is a bleeding hole on the thermostatic plate at the other end of the blood tank, communicating with the blood tank. A blood injection tube is fixedly installed at the upper end of the blood inlet hole. A transparent blood overflow tube is fixedly installed at the upper end of the bleeding hole. The upper part of the blood injection tube and the upper part of the blood overflow tube are located on the outside of the constant temperature water tank. A temperature monitoring device is installed on the constant temperature water tank. In this patent, insects attach to the biofilm and suck the blood that seeps from the biofilm. Warm water is supplied to the constant temperature water tank to maintain the breeding temperature, and ice water is supplied to the constant temperature water tank to reduce the activity of the insects, so that the insects float down from the biofilm and are collected. Finally, the insects on the biofilm are sorted out. However, during the breeding process, because the surface of the biofilm itself is relatively smooth and the bottom of the biofilm is suspended, it is difficult for fleas to attach to the biofilm to suck blood. At the same time, because fleas have the habit of gathering together, when it is difficult to attach to the biofilm, fleas will gather at the corner where the biofilm and the insect collection funnel are connected. Due to the small space and insufficient blood supply at the corner, the blood-sucking rate is low and the breeding effect is not good. Utility Model Content

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the described embodiments are merely some, not all, of the embodiments of this utility model. Unless otherwise specified, the embodiments and features described in this application can be combined with each other. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0015] In one embodiment, see Figure 1 , 2 The present invention relates to a flea breeding device, comprising a breeding component and a temperature control component.

[0016] The feeding assembly includes a feeding tank 1 and a detachable culture tank 2 located at the bottom of the feeding tank 1. The bottom inner wall of the feeding tank 1 has a flow guiding cavity 3. A blood storage component 4 is detachably located inside the bottom of the feeding tank 1. A biofilm 5 is detachably located on the blood storage component 4. Multiple sets of feeding components 6 are arranged at intervals on the end of the biofilm 5 away from the blood storage component 4. A gap is left between the blood storage component 4 and the feeding tank 1 to form a blood storage space 7. The bottom end of the blood storage component 4 has a bleeding hole 8 that communicates with the biofilm 5. The culture tank 2 encloses the biofilm 5 and has a gap to form a culture space 9. The temperature control assembly includes a heating element 10 located inside the feeding tank 1 and a temperature sensor 11 located inside the feeding tank 1. The heating end 12 and the cooling end 13 of the heating element 10 are respectively connected to the flow guiding cavity 3 and are provided with an air supply component 14.

[0017] Further, see Figure 2The feeding tank 1 is provided with a partition plate 15, which divides the interior of the feeding tank 1 into a temperature control space 16 and an installation space 17. The heating element 10 is installed on the partition plate 15. The top of the feeding tank 1 is provided with a cover plate to seal the temperature control space 16. The cover plate is provided with a first air inlet groove 18 and a second air inlet groove 19 that are connected to the heating end 12 and the cooling end 13 of the heating element 10, respectively.

[0018] Preferably, the rearing tank 1 is a hollow cylindrical tank. A partition plate 15 is installed in the upper half of the rearing tank 1 to separate the interior of the rearing tank 1. The part above the partition plate 15 is the temperature control space 16, and the part below the partition plate 15 is the installation space 17. The heating element 10 is installed on the partition plate 15. The blood storage unit 4, the biofilm 5, and the culture tank 2 are all located at the bottom of the rearing tank 1. The heating element 10 in the temperature control space 16 is installed with the blood storage unit 4 at an interval of the installation space 17. Therefore, the heating element 10 will not affect the temperature inside the blood storage unit 4, the biofilm 5, and the culture tank 2.

[0019] Preferably, the heating element 10 adopts a semiconductor cooling chip in the existing structure, with the two ends of the semiconductor cooling chip connected to the heating end 12 and the cooling end 13, respectively.

[0020] Preferably, to separate the heating end 12 and cooling end 13 of the heating element 10, a vertical partition 20 is also provided on the partition plate 15. The vertical partition 20 has an installation cavity in the middle. The vertical partition 20 divides the temperature control space 16 into two areas. The heating element 10 is installed in the installation cavity. The heating end 12 and cooling end 13 of the heating element 10 are located in the spaces on both sides of the vertical partition 20, and a sealing insulation layer is filled in the gap between the installation cavity and the heating element 10, thereby separating the cooling end 13 and the heating end 12 of the heating element 10. Since the cooling efficiency of the semiconductor cooling chip is related to the heat dissipation effect of the heating end 12, a sealing insulation layer can be provided on the vertical partition 20, the partition plate 15, the side wall of the temperature control space 16, and the cover plate, thereby separating the heating end 12 and the cooling end 13 of the heating element 10.

[0021] It should be noted that, since the breeding tank 1 and culture tank 2 in this application are mainly used to raise insects, fleas, etc., their volume requirements are not large (5cm-10cm in diameter and 15cm-20cm in height). The cooling effect of the semiconductor cooling chip can fully guarantee rapid cooling when cooling is required. Of course, in order to ensure the cooling effect, multiple sets of semiconductor cooling chips can also be installed on the vertical partition 20 to improve the cooling or heating efficiency.

[0022] It should be further explained that, in order to improve the cooling or heat dissipation effect at both ends of the thermoelectric cooler, heat sinks 21 are installed on both sides of the vertical partition 20 to absorb energy, thereby accelerating the dissipation of heat at the heating end 12 of the thermoelectric cooler or accelerating the collection of cold air at the cooling end 13 of the thermoelectric cooler.

[0023] Further, see Figure 2 The side wall of the temperature control space is provided with a first air outlet pipe 22 and a second air outlet pipe 23, which are connected to the heating end 12 and the cooling end 13 of the heating element 10, respectively. The first air outlet pipe 22 and the second air outlet pipe 23 are respectively connected to the guide cavity 3.

[0024] Preferably, the first air outlet pipe 22 and the second air outlet pipe 23 are located within the installation space 17, and are respectively arranged adjacent to the inner wall of the installation space 17, thereby increasing the distance between the first air outlet pipe 22 and the second air outlet pipe 23. The air supply component 14 adopts a fan, with two sets of fans located on both sides of the vertical partition 20. After the fan located in the heating end 12 of the heating component 10 is working, it discharges the heat generated by the heating component into the first air outlet pipe 22. The heat enters the guide cavity 3 to heat the blood storage space 7 and the culture space 9, ensuring the temperature in the blood storage space 7, so that the blood in the blood storage space 7 can flow into the biofilm 5 through the bleeding hole 8 and diffuse. At the same time, it heats the culture space 9, ensuring that the temperature in the culture space 9 is suitable for flea survival.

[0025] Further, see Figure 2 The bottom of the breeding tank 1 is provided with a connecting sleeve 24. The flow guiding cavity 3 is located in the inner wall of the bottom of the breeding tank 1 and the inner wall of the connecting sleeve 24. After the blood storage component 4 and the culture tank 2 are connected to the breeding tank 1 respectively, the connecting sleeve 24 is located inside the culture tank 2. The entire flow guiding cavity 3 can be divided into a part located at the bottom of the breeding tank 1 and a part located in the inner wall of the connecting sleeve 24. The part located at the bottom of the culture tank 2 is below the blood storage component 4, which can provide heat or cold air to the blood storage component 4. The part located inside the connecting sleeve 24 is located below the blood storage component 4, which can provide heat or cold air to the culture space 9.

[0026] Preferably, the connecting sleeve 24 is integrally formed with the feeding tank 1, and the connecting sleeve 24 is a hollow cylinder with openings at both ends.

[0027] Preferably, the cross-section of the flow guiding cavity 3 in the vertical direction is an inverted "U" shape.

[0028] In the above setup, when it is necessary to heat the blood storage space 7 and the culture space 9 to maintain a suitable temperature, the heater power supply is turned on. The heater uses a semiconductor cooling chip, and usually requires a separate power adapter to convert household power to 12V / 24V power. These are all existing technologies and will not be described in detail in this application. After the heating element 10 is working, the heating end 12 generates a large amount of heat and presses the fan switch inside the heating end. The fan works to draw in outside air from the first air inlet slot 18. The drawn-in air transfers the heat from the heating end 12 through the first air outlet pipe 22 into the guide space to heat the blood storage space 7 and the culture space 9. The temperature is monitored by the temperature sensor 11. At the same time, a temperature controller electrically connected to the temperature sensor 11 is set externally to realize real-time temperature monitoring in the blood storage space 7 and the culture space 9, providing a suitable temperature for flea survival and allowing the blood to be warmed up to facilitate permeation from the biofilm 5 for adjusted feeding. The hot air entering the flow cavity 3 is discharged from the second exhaust pipe 23 into the cooling end 13 of the heating element 10, and then discharged to the outside through the second air inlet 19. When it is necessary to cool down the blood storage space 7 and the culture space 9, the fan in the cooling end 13 of the heating element 10 is started, the fan in the heating end 12 is turned off, and the fan in the cooling end 13 draws in the outside air from the second air inlet 19, cools it through the heat sink 21, and then discharges it into the flow cavity 3 through the second exhaust pipe 23, thereby cooling down the blood storage space 7 and the culture space 9. The low-temperature gas is discharged along the first exhaust pipe 22 and the first air inlet 18. The cooling end 13 and heating end 12 of the heating element 10 are connected through the first air outlet pipe 22, the guide cavity 3, and the second air outlet pipe 23. When using the cooling end 13 of the heating element 10, since the cooling efficiency of the semiconductor cooler is related to the heat dissipation efficiency of the heating end 12, the higher the heat dissipation efficiency of the heating end 12, the better the cooling efficiency of the semiconductor cooler. Therefore, passing the cold air from the cooling end 13 into the heating end 12 can improve the heat dissipation efficiency of the heating end 12, thereby improving the cooling efficiency. This results in a low temperature of the cold air in the guide cavity 3, which can quickly cool down the fleas.

[0029] Further, see Figure 2 The blood storage component 4 includes a blood storage cylinder, and the top of the blood storage cylinder and the bottom of the feeding tank 1 are respectively provided with connectors 25, so that the two can be detachably connected.

[0030] Preferably, the blood storage cylinder is a hollow cylinder with one open end. The connector 25 is a magnet, which is located on the open end face of the blood storage cylinder. The blood storage cylinder is connected to the feeding tank 1 by the magnet. There is a space between the inside of the blood storage cylinder and the bottom end of the feeding tube to form a blood storage space 7. The biofilm 5 is fixed to the closed end of the blood storage cylinder by adhesive. The blood storage holes are spaced at the closed end of the blood storage cylinder. The blood stored in the blood storage cylinder can fall into the biofilm 5 along the blood storage holes and diffuse.

[0031] Further, see Figure 2 To facilitate blood filling, the feeding tank 1 is equipped with a filling pipe 26 that communicates with the blood storage space 7, and the filling pipe 26 is equipped with a sealing cap 27.

[0032] Preferably, the filling tube 26 and the sealing cap 27 are connected by threads.

[0033] Further, see Figure 2 The feeding device 6 includes feeding hair bundles spaced apart inside the culture tank 2, with the top of the feeding hair bundles abutting against the bottom of the biofilm 5.

[0034] Preferably, the culture tank 2 is a hollow cylinder with one open end. The culture tank 2 is threadedly connected to the feeding tank 1. The inner diameter of the culture tank 2 is larger than the outer diameter of the feeding tank 1. The feeding hair bundle is made of twisted rat hair held in place by steel wire. After the culture tank 2 rotates and connects to the feeding tank 1, the top of the feeding hair bundle abuts against the bottom of the biofilm 5. The feeding hair bundle provides a habitat for fleas and disperses the fleas to avoid accumulation. After the blood on the biofilm 5 diffuses, the fleas located on the feeding hair bundle can suck it up. After dispersing the fleas, the blood-sucking rate can be increased.

[0035] It should be noted that, in order to facilitate observation of the fleas in culture tank 2, culture tank 2 can be made of transparent plastic material.

[0036] In this embodiment, when raising fleas, the biofilm 5 is connected and fixed to the blood storage cylinder, and then the blood storage cylinder is placed in the bottom of the raising tank 1. The fleas whose activity has been reduced after low-temperature treatment (the captured fleas can be placed in ice water or a refrigerator for low-temperature treatment) are placed in the culture tank 2. The culture tank 2 is connected to the raising tank 1. Blood is added to the blood storage space 7 through the injection tube 26. The blood falls onto the biofilm 5 through the bleeding hole 8. The power supply of the heating element 10 is turned on and the fan of the heating end 12 is started. Hot air is sent into the guide cavity 3 to heat the bleeding space and the culture space 9. The heating temperature is controlled to raise fleas. The fur tufts provide multiple positions for the fleas to separate them and avoid fleas from huddling together, thereby increasing the blood-feeding rate of the fleas. After raising is completed, the fan motor of the heating end 12 of the heating element 10 is turned off and the fan power of the cooling end 13 of the heating element 10 is turned on. Cold air enters the guide cavity 3 to cool the blood storage chamber and the culture chamber. After reducing the flea activity, the culture tank 2 is separated from the raising tank 1, so that the fleas can be taken out.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
