Description

Technical Field

[0001] The utility model belongs to the technical field of cockroach-killing glue baits, and in particular relates to a syringe-type cockroach-killing glue bait. Background Art

[0002] Currently, cockroach gel bait is a commonly used cockroach control method. It kills cockroaches by enticing them to eat a gel-like substance containing insecticide. The following are some of the advantages and disadvantages of cockroach gel bait:

[0003] Advantages: Long-lasting: Once placed, glue baits can continue to work for weeks or even months, continuously attracting and killing cockroaches. Safe: Compared to sprays, glue baits are less toxic and pose less risk to humans and pets. Easy to use: Simply place the glue bait in areas where cockroaches are present, no specialized equipment or skills required. Odorless: Glue baits are typically odorless or have a mild odor, unlike some sprays that can cause discomfort. Strong Attraction: The bait in the glue bait attracts cockroaches to feed, thereby enhancing the effectiveness of the elimination process.

[0004] In terms of defects, the effect is slow: the glue bait needs to be fed by cockroaches before it works, so the effect may not be as quick as the spray. Limitations: The glue bait is mainly aimed at cockroaches that feed, and may not be as effective for cockroaches that do not feed. Environmental factors: If the home environment is unsanitary, the cockroach problem may not be completely solved by glue bait, and other cleaning and prevention measures must be combined. Therefore, drugs are needed to lure cockroaches to feed on the glue bait. Since different drugs have different lethal properties for different cockroaches, different attractant formulas have different effects on attracting and feeding different cockroaches. It is necessary to independently set glue baits with different drug formulas in the same drug extrusion device, and be able to extrude two glue baits with different drug formulas at the same time. However, common extrusion devices are not convenient for simultaneously accommodating and extruding two independently placed drugs, or the structure is complex and inconvenient to use.

[0005] Therefore, a new technology is needed to solve the problem that the device capable of simultaneously accommodating and extruding two drugs in the prior art has a complex structure and is inconvenient to use. Utility Model Content

[0006] In order to solve the above-mentioned problems in the prior art, the utility model provides a syringe-type cockroach-killing glue bait. The glue bait extrusion device can simultaneously accommodate and extrude two independently placed glue baits. Different attractants can be added to different glue baits to achieve double-formula application, thereby enhancing the attractiveness and palatability to cockroaches, having a better cockroach-killing effect and improving cockroach feeding habits. It has a simple structure and is easy to apply and use.

[0007] The utility model adopts the following technical solutions:

The first flexible bag and the second flexible bag can be simultaneously accommodated in the cannula and are parallel to each other along the axis of the cannula. One end of the piston rod can extend into the syringe at the tail end. When the piston rod moves toward the needle end, the glue bait in the first flexible bag and the second flexible bag can be squeezed out from the needle end.

[0013] As a further improvement of the technical solution of the present invention, a sealing plug is detachably installed on the side of the extrusion portion away from the limiting plate. The sealing plug is elastic, and the radial dimension of the sealing plug in the cylinder is not less than the inner diameter of the cylinder.

[0030] Reference Figures 1 to 4 A syringe-type cockroach glue bait comprises a syringe 1, a piston rod 2, a cannula, a first flexible bag 3, and a second flexible bag 4. The syringe 1 can preferably be a hard syringe 1. The first flexible bag 3 and the second flexible bag 4 are both used to hold glue bait. The syringe 1 has a needle end 13 and a tail end 14. The cannula can be inserted into the syringe 1 at the tail end 14. The cannula is used to simultaneously place the first flexible bag 3 and the second flexible bag 4 into the syringe 1. The first flexible bag 3 and the second flexible bag 4 can be accommodated in the cannula at the same time and are parallel to each other along the axis of the cannula. One end of the piston rod 2 can extend into the syringe 1 at the tail end 14. When the piston rod 2 moves toward the needle end 13, the glue bait in the first flexible bag 3 and the second flexible bag 4 can be squeezed out from the needle end 13. Before using glue baits, such as cockroach baits, two flexible bags are inserted into the cannula, which is then inserted into the rigid syringe 1. The cannula is then removed, leaving the two flexible bags inside the syringe 1, allowing for simultaneous storage of glue baits of different formulations. During use, the piston rod 2 is inserted into the tail end 14 and gently pushed, squeezing out the different formulations of glue bait from the needle end 13 for easy dual-formulation administration.

[0031] This syringe-type cockroach-killing gel bait requires only a single syringe (1), resulting in low material costs. Its simple structure and low mold costs are also required for manufacturing. Different attractants can be added to different gel baits contained in different flexible bags within the same syringe (1), achieving dual-formula application. This enhances cockroach attraction and palatability, resulting in better cockroach killing and increased feeding habits. By placing two flexible bags within a single rigid syringe (1), dual-formula application can be achieved simultaneously. Application is convenient, requiring only a single squeeze, eliminating the need for separate syringes (1) to extrude different gel bait formulations.

[0032] Specifically, the syringe 1 includes a barrel 11 and an extrusion tube 12 that are interconnected. The end of the barrel 11 away from the extrusion tube 12 is the tail end 14, and the end of the extrusion tube 12 away from the barrel 11 is the needle end 13. The inner diameter of the barrel 11 is larger than the inner diameter of the extrusion tube 12. The outer diameter of the cannula is smaller than the inner diameter of the barrel 11 and larger than the inner diameter of the extrusion tube 12. The length of the cannula is greater than the length 11 of the barrel. The outer diameter of the piston rod 2 is adapted to the inner diameter of the barrel 11. The length of the cannula can be greater than the length 11 of the barrel, which facilitates removal of the cannula after the two flexible bags are placed in the barrel 11.

[0033] Specifically, the first flexible bag 3 and the second flexible bag 4 have identical or similar structures. The first flexible bag 3 has a filling port at one end and a drug outlet at the other end. The filling port is located near the tail end 14 and is provided with a first seal 31 for closing the filling port. The drug outlet is located near the needle end 13 and is provided with a second seal for closing the drug outlet. When the first flexible bag 3 is located within the barrel 11, the two second seals can pass through the extrusion tube 12 and extend outside the extrusion tube 12. A pair of flexible bags are inserted into a cannula, which is then inserted into the rigid syringe 1. The cannula is then removed and the two flexible bags are left in the syringe 1. A second seal is provided at the first end of each flexible bag near the needle end 13. The glue bait drug is filled into each flexible bag at the tail end 14 of the rigid syringe 1. The two flexible bags can each be filled with a different glue bait drug. After filling, a first seal 31 is provided at this end of the flexible bag. The first seal 31 is pressed into the rigid syringe 1. During use, the piston rod 2 is inserted into the rear end 14 of the syringe 1. After that, the second seal on each flexible bag is cut off. The piston rod 2 is gently pushed to squeeze out the glue bait from the nozzle of the extrusion tube 12. This solution has low mold and material costs. Two flexible bags can be placed in a rigid syringe 1 to achieve simultaneous dual-formula drug application. The drug application method is convenient and can be applied in one shot, eliminating the need to use two syringes 1 to extrude different glue baits.

[0034] Specifically, an annular plate 111 is protruded from the side surface of the cylinder 11 at the tail end 14 . The annular plate 111 is provided to facilitate application of force when pushing the piston rod 2 .

[0035] Specifically, the piston rod 2 includes a rod body 21 and a limiting plate 22. The limiting plate 22 is fixed to one end of the rod body 21. The other end of the rod body 21 is provided with an extrusion portion. The rod body 21 can extend into the cylinder body 11. The size of the extrusion portion is adapted to the inner diameter of the cylinder body 11 so that the extrusion portion can smoothly move with the rod body 21 within the cylinder body 11. When the rod body moves, the extrusion portion can contact and squeeze the first flexible bag 3 and the second flexible bag 4. The radial size of the limiting plate 22 is larger than the size of the cylinder body 11, that is, the limiting plate 22 cannot extend into the cylinder body 11. The provision of the limiting plate 22 can prevent the piston rod 2 from being fully inserted into the cylinder body 11, making it difficult to remove the piston rod 2. When in use, the rod body 11 can be pushed by pressing the limiting plate 22 to move relative to the cylinder body 11 along the axial direction of the cylinder body 11.

[0036] Specifically, a sealing plug 23 is removably mounted on the end of the rod 21 away from the stop plate 22. The radial dimension of the sealing plug 23 is no less than the inner diameter of the cylinder 11, and the side surface of the sealing plug 23 is capable of close contact with the inner wall of the cylinder 11, providing a sealing effect. When the rod 21 moves toward the needle end 13, the end of the sealing plug 23 away from the stop plate 22 contacts the first and second flexible bags 3 and 4, evenly squeezing the glue bait within them. The elasticity of the sealing plug 23 reduces or prevents damage to the first and second flexible bags 3 and 4. The provision of the sealing plug 23 also prevents the glue bait within the cylinder 11 from leaking from the tail end 14 or the side surface of the sealing plug 23 if the first and second flexible bags 3 and 4 rupture. In one embodiment, the sealing plug 23 is removably mounted on the side of the squeezing portion away from the stop plate 11.

[0037] In another embodiment, a sealing plug 23 is detachably mounted on one end of the rod body 21 away from the limiting plate 22 , and the sealing plug 23 forms the extrusion portion.

[0038] When preparing the colloid in each flexible bag of the syringe-type cockroach killing glue bait of this scheme, the raw materials are weighed according to the formula ratio, and water and carrageenan are mixed at 92°C in an emulsifying device. After dissolution, heating is stopped, and xanthan gum is added after the temperature drops to 80-90°C, and the mixture is stirred evenly. Other raw materials are added and stirred evenly before discharging. The colloids with the two prepared drug ratios are filled into the first flexible bag and the second flexible bag respectively, and the first flexible bag and the second flexible bag are sealed after filling. Then, the first flexible bag and the second flexible bag are sent into the syringe through the cannula. In the process of injecting the colloid, 10mL of colloid A can be injected into the first flexible bag, and 10mL of colloid B can be injected into the second flexible bag, and then the first flexible bag and the second flexible bag are sealed.
