Description

Technical Field

[0001] The utility model relates to the technical field of cockroach catching devices, in particular to a cockroach catching device. Background Art

[0002] Cockroaches are an ancient insect. Studies have found that they prefer to live in warm, humid, dark places with abundant food and many cracks. They have a short life cycle and strong reproductive capacity. They have become the most common and difficult to control urban health pests in the world. Because wild cockroaches and laboratory-raised cockroaches have different resistance and dietary characteristics, controlling live wild cockroaches can verify the feasibility of existing and newly developed cockroach control methods. Therefore, capturing live wild cockroaches is the key point of experimental research.

[0003] In the past, live wild cockroaches were usually captured by hand, which was not only time-consuming and laborious, but also difficult for the captured cockroaches to survive in the laboratory due to broken legs or severe infestation. Therefore, it is necessary to use a cockroach capture device to capture live wild cockroaches.

[0004] Existing cockroach catching devices are mainly divided into the following three categories: the first category is a cockroach box with poisonous erbium, called cockroach bait, which is used to attract cockroaches to feed and poison them and kill them, and is not applicable. The second category is cockroach sticky catching, such as cockroach catching boards and cockroach houses, which use cockroach attractants and glue without lethal drugs to attract cockroaches to the adhesive layer, and stick them to death, but they are also not applicable because they cannot be caught alive. The third category is a cockroach trap with a flap "door" or a suspended "trumpet" that allows cockroaches to "enter but not exit" and can be caught alive. Therefore, existing cockroach catching devices all use the third category, but during the catching process, cockroaches will not easily enter because the "door" and "trumpet" bring "unsafe" factors to the cockroaches, and the catching effect is poor. This is because the trapping device with a flap "door" requires the cockroach to push open the flap "door", and the cockroach's antennae are in front of the head. When the obstacle is detected, most cockroaches just stay at the door and do not enter. For the device with a suspended "trumpet", the trumpet is located at the top downward, and cockroaches usually cannot easily detect the trumpet at the bottom. Even if the trumpet is detected, the cockroaches will have obvious hysteresis when entering the entrance area due to its suspended state, and most cockroaches do not enter.

[0005] Therefore, designing a cockroach catching device that is easy for cockroaches to enter and does not harm living cockroaches is of great value and significance. Utility Model Content

[0012] Preferably, the spacing between the first circulation gap and the second circulation gap is greater than 6 mm.

[0013] Preferably, the distance between the first circulation gap and the second circulation gap is 6 mm-1.2 mm for the first circulation gap.

[0014] Preferably, it further comprises a fixer, wherein the fixer is used to fix the cockroach bait on the partition assembly;

[0015] The fixer comprises a fixing seat and a fixing tip, and the fixing tip can be inserted into the partition assembly.

[0016] Preferably, the water feeder consists of a bottle body, a soft plug and a water absorption rod, and the soft plug fits tightly with the bottle body and the water absorption rod.

[0017] Preferably, the partition assembly includes a transverse long pallet, a transverse short pallet, a vertical long pallet and a vertical short pallet, and a plurality of grooves are provided on the transverse long pallet, the transverse short pallet, the vertical long pallet and the vertical short pallet along the length direction, and the transverse long pallet and the transverse short pallet form a snap-fit ​​structure with the vertical long pallet and the vertical short pallet through the grooves.

[0018] Preferably, the number of the transverse long pallets is 2, the number of the transverse short pallets is 2, the number of the vertical long pallets is 2, and the number of the vertical long pallets is 4;

[0019] The two horizontal long pallets, the two horizontal short pallets, the four vertical long pallets and the two vertical short pallets are engaged with each other, the two horizontal short pallets are located between the two horizontal long pallets, the two vertical short pallets are located between the four vertical long pallets, and the isolation cabin located in the middle is used for placing cockroach bait and a water feeder.

[0020] Preferably, the front-to-back depth of the outer frame is 3.2-22 cm, and the length and width of the outer frame are 2.2-12 cm and 1.8-6 cm respectively;

[0021] The inner frame surface of the outer frame contacts the bottom of the isolation cabin, and the spacing distance between the outer frame and the front, rear, left, right and top of the isolation cabin is 0.6-1 cm.

[0022] Preferably, a connection structure is provided at the joint between the outer frame and the cover body;

Furthermore, since the partition assembly separates the inner cavity into a plurality of isolation chambers for cockroaches to inhabit, and the isolation chamber located in the middle is used to place cockroach bait and a water feeder, the cockroach capture device has various cockroach-friendly characteristics such as water intake, food intake, and inhabitation. When cockroaches enter the trapping box, they can move around through the cockroach circulation through hole and the first circulation gap to obtain water and food. The design of the through hole is increased to facilitate the free movement of cockroaches to a certain extent, expand the activity space, increase their residence time in the device, enhance air flow to a certain extent, and reduce local areas from being too dry or too wet. Therefore, more cockroaches will enter and fewer will come out within a certain period of time, forming a dynamic balance, so that they gather in the cockroach capture device, achieving the purpose of easily trapping live cockroaches.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, the meaning of "plurality" is two or more.

[0038] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] like Figure 1-5 As shown, a cockroach catching device comprises an outer frame 1, a cover body 2 and a partition assembly 3;

[0040] The partition assembly 3 is detachably arranged in the inner cavity of the outer frame 1, and the partition assembly 3 does not protrude from the inner cavity. The partition assembly 3 separates the inner cavity into a plurality of isolation cabins 4 for cockroaches to inhabit, and the isolation cabin 4 located in the middle is used to place cockroach bait and a water feeder 5;

[0041] The partition assembly 3 is provided with a plurality of flow holes 30, and at least one first flow gap 6 is left from the edge of the partition assembly 3 to the inner cavity wall of the inner cavity;

[0042] The outer frame 1 has two front and rear opposite flow ports, and the two flow ports are detachably mounted with the cover body 2, and the area of ​​the cover body 2 is smaller than the area of ​​the flow port. At least one second flow gap 7 is left from the edge of the cover body 2 to the edge of the flow port, and the second flow gap 7 is connected to the inner cavity.

[0043] Compared with the prior art design of a "door" with a flap, or a design of a suspended "trumpet", the utility model uses the outer frame 1 and the cover 2 to form a second flow gap 7 for cockroaches to enter and exit the inner cavity, thereby changing the previous design concept of "entry but no exit" to "dynamic capture", that is, cockroaches can freely enter and exit the capture box, and the structure of the outer frame 1 and the cover 2 is simple, low cost, and the appearance of the entire cockroach capture device is simple and beautiful. Further, because the partition assembly 3 isolates the inner cavity into a plurality of isolation cabins 4 for cockroaches to inhabit, and the isolation cabin 4 located in the middle is used to place cockroach bait and water feeder 5, the cockroach capture device has various cockroach-friendly characteristics such as taking water, taking food, and inhabiting. When cockroaches enter the trapping box, they can move around through the cockroach flow through hole 30 and the first flow gap 6 to obtain water and food, which is convenient for cockroaches to move freely to a certain extent, expand the activity space, increase their residence time in the device, enhance air flow to a certain extent, and reduce excessive dryness or excessive humidity in local areas. Therefore, in a certain period of time, more cockroaches will enter and fewer will come out, forming a dynamic balance, so that they gather in the cockroach catching device, achieving the purpose of easily trapping living cockroaches.

[0044] To further explain, the spacing L between the first circulation gap 6 and the second circulation gap 7 is greater than 6 mm.

[0045] Since cockroaches have the habit of resting during the day and coming out at night, they spend most of their lives in a resting state and like to live in dark narrow crevices, which are relatively secretive and close to food and water sources. Cockroaches like to eat "conveniently". If the feeding method is too complicated, they will take more convenient measures. The design of the size of the first circulation gap 6 and the second circulation gap 7 is particularly critical. If the first circulation gap 6 and the second circulation gap 7 are too large or too small, it is not conducive to their entry.

[0046] Therefore, in this embodiment, the outer frame 1 has two front and rear opposite flow ports, and forms a first flow gap 6 and a second flow gap 7 for relative flow, so that the capture device forms a structure with a certain slit flow and a hidden characteristic inside, which is conducive to the inhabitation of cockroaches.

[0047] Preferably, the spacing L between the first flow gap 6 and the second flow gap 7 is 6mm-1.2mm. This is because the body length of German cockroach nymphs is generally 2-5mm, and the body length of adults is 10-15mm, so the size of the first flow gap 6 and the second flow gap 7 is designed to be 6mm-12mm. At this time, the openings of the first flow gap 6 and the second flow gap 7 are not too large, and the inner cavity can accommodate cockroaches of different ages; at the same time, the first flow gap 6 and the second flow gap 7 of this size form a narrow gap with the device, which meets the habit of cockroaches to live in narrow gaps.

[0048] Further explanation, it also includes a fixer 8, and the fixer 8 is used to fix the cockroach bait on the partition assembly 3;

[0049] The fixer 8 includes a fixing seat 81 and a fixing tip 82 , and the fixing tip 82 can be inserted into the partition assembly 3 .

[0050] It should be noted that the cockroach bait has a strong attraction to cockroaches and good palatability, and can be fixed on the partition assembly 3 by a fixer 8, or has a certain viscosity and can be attached to the partition assembly 3.

[0051] To further explain, the water feeder 5 is composed of a bottle body 51 , a soft plug 52 and a water absorption rod 53 , and the soft plug 52 is tightly fitted with the bottle body 51 and the water absorption rod 53 .

[0052] It should be noted that the bottle body 51 is made of transparent plastic for easy viewing of the water volume. The material of the soft plug 52 has a certain degree of softness, such as PU, nylon, S, etc., and can fit tightly to the bottle mouth of the bottle body 51 and fix the water absorption rod 53. The water absorption rod 53 is cylindrical, including cellulose fiber and polyimide fiber, has water absorption capacity, and has a saturated water absorption rate of 8%-15%. It can drain the water in the bottle body 51 to the bottle mouth for cockroaches to suck.

[0053] To further explain, the partition assembly 3 includes a transverse long pallet 31, a transverse short pallet 32, a vertical long pallet 33 and a vertical short pallet 34. The transverse long pallet 31, the transverse short pallet 32, the vertical long pallet 33 and the vertical short pallet 34 are each provided with a plurality of grooves 35 along the length direction. The transverse long pallet 31 and the transverse short pallet 32 ​​form a snap-fit ​​structure with the vertical long pallet 33 and the vertical short pallet 34 through the grooves 35.

[0054] A partition assembly 3 is arranged inside the outer frame 1 to form a plurality of isolation compartments 4, which are convenient for accommodating cockroaches of different ages to enter. A horizontal long card board 31, a horizontal short card board 32, a vertical long card board 33 and a vertical short card board 34 are installed together by a snap-fit ​​structure. The horizontal long card board 31 and the horizontal short card board 32 are installed together for easy installation and disassembly.

[0055] Further explanation, the number of the horizontal long pallets 31 is 2, the number of the horizontal short pallets 32 is 2, the number of the vertical long pallets 33 is 2, and the number of the vertical long pallets 33 is 4;

[0056] The two transverse long pallets 31, the two transverse short pallets 32, the four vertical long pallets 33 and the two vertical short pallets 34 are engaged with each other, the two transverse short pallets 32 are located between the two transverse long pallets 31, the two vertical short pallets 34 are located between the four vertical long pallets 33, and the isolation cabin 44 located in the middle is used to place cockroach bait and water feeder 5.

[0057] After testing, the partition assembly 3 under the number of the above embodiments can capture a large number of cockroaches and is more practical. Moreover, the front and rear depths of the outer frame 1 are 3.2-22cm, and the length and width of the outer frame 1 are 2.2-12cm and 1.8-6cm respectively; and the inner frame surface of the outer frame 1 is in contact with the bottom of the isolation cabin 4, and the spacing distance between the outer frame 1 and the front, rear, left, right and top of the isolation cabin 4 is 0.6-1cm, which is better under the size limitation. After analysis, this is because when the cockroaches enter the trapping device, they only need to pass through 1-2 partitions and the circulation through hole 30 to reach the isolation cabin 4 where baits such as feed and water are placed; and the route from the cockroaches entering the trapping device to eating the feed is not too complicated, and they will not leave directly after eating.

[0058] To further illustrate, a connection structure 9 is provided at the covering portion of the outer frame 1 and the cover body 2;

[0059] The connecting structure 9 includes a first connecting portion 91 and a second connecting portion 92, one of which is arranged on one side of the outer frame 1, and the other of the first connecting portion 91 and the second connecting portion 92 is arranged on the corresponding side of the cover body 2, the first connecting portion 91 includes at least one connecting hole, and the second connecting portion 92 includes at least one connecting block, which is inserted into the corresponding connecting hole.

[0060] In this embodiment, a connection structure 9 is provided at the joint of the outer frame 1 and the cover body 2, so that the cover body 2 can be detachably connected to the outer frame 1 under the limiting action of the connection block. Through this connection structure 9, the present application can form a second flow gap 7 between the outer frame 1 and the cover body 2 while ensuring the overall connection strength.

[0061] It should be noted that the connection structure 9 can be replaced by a known driving structure, such as a connection column and a connection hole, a block and a buckle, etc.; as long as it can achieve installation between the outer frame 1 and the cover body 2, it should be within the protection range.

[0062] To further explain, the partition assembly 3 is made of solid board or corrugated board.

[0063] In one optional embodiment, the partition assembly 3 is made of solid board, which is easy to process, low in cost and convenient to clean. In another optional embodiment, the partition assembly 3 is made of corrugated board, which is non-toxic, pollution-free and waterproof, making it easy for cockroaches to stay and accommodating more cockroaches.

[0064] The method of using the cockroach catching device is as follows: select an appropriate location to place it, retrieve it within a certain period of time, and collect the cockroaches that inhabit and feed therein into the cockroach breeding device. The specific detailed implementation method is as follows:

[0065] Experimental process: Prepare several uncovered storage boxes with a length of 50cm, a width of 40cm, and a height of 30cm. Apply a circle of Vaseline around them to prevent cockroaches from escaping. Then put 100 German cockroach adults and 50 German cockroach larvae of different ages in each box. After the test insects are stable, put different cockroach catching devices containing feed and water in the middle of the storage box. After 24 hours, take out the cockroach catching device and place it in a storage box with Vaseline on all sides. Shake the cockroach catching device, and the cockroaches will be shaken out into the storage box. Record the number of adults and larvae respectively.

[0066] Embodiment 1: The cockroach catching device, the cockroach catching device with a flap door or a trumpet in the prior art, and the cockroach catching device made of a plastic bottle are compared and tested. Figure 7 As shown, the cockroach trap made of plastic bottle is as shown Figure 8 shown.

[0067] The test results are as follows:

[0068]

[0069] Embodiment 2: A comparative test is performed by changing the size of the flow slits 5 , the number of the flow slits 5 and the number of the partition assemblies 3 in the cockroach catching device.

[0070] The test results are as follows:
