Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of cockroach traps, specifically a cockroach trap with an escape-proof structure. Background Technology
[0002] A cockroach trap is a small household or commercial device that lures and captures cockroaches. It typically consists of a plastic shell (including an entrance channel and a trap chamber), an attractant (containing cockroach pheromones, food baits such as brown sugar, and oil extracts), and an adhesive layer (high-viscosity environmentally friendly glue). Some models have built-in cockroach viruses or low-toxicity insecticides to enhance the killing effect. It is suitable for areas where cockroaches are prone to appear, such as kitchens and bathrooms, and serves as a supplement to chemical sprays to achieve physical trapping and long-term control.
[0003] To this end, China Patent Network published a cockroach trap with application number 202321695746.X. The trap consists of a base and a trapping tube mounted on top of the base. A bait hopper is located in the middle of the top of the base, containing bait. An inlet pipe is located in the middle of the inside of the trapping tube, with its upper end connected to the trapping tube. A support plate is located below the outside of the inlet pipe, and a first rotating rod and a second rotating rod are respectively rotatably mounted on both sides of the support plate via bearing seats. The first rotating rod has a first blade. When bait is placed in the bait hopper, it releases an odor to attract cockroaches. The odor is emitted from the inlet pipe, and cockroaches, attracted by the odor, enter the inlet pipe. During this process, a drive block drives the first and second rotating rods to rotate, and the first and second blades interlock in the insertion slot, cutting up the cockroaches that have entered the inlet pipe and causing them to fall onto the base. When cleaning, the trapping tube is opened, and no cockroaches can escape.
[0004] While the above-mentioned applications meet the user's needs to a certain extent, there are still some defects in their use. The specific problems are as follows: existing cockroach traps are mostly integrated units, which makes it inconvenient for staff to disassemble and clean them later. At the same time, it is also inconvenient to prevent cockroaches that fall into the trap from escaping, making it easy for cockroaches to escape. Based on this, this utility model designs a cockroach trap with an escape-prevention structure to solve the above problems. Utility Model Content

[0021] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0022] Example: Figure 1-4 As shown, this utility model provides a technical solution for a cockroach trap with an escape-proof structure, including an upper bucket 1. A lower bucket 2 is threadedly connected to the bottom inner side of the upper bucket 1. The bottom inner side of the lower bucket 2 stores boric acid liquid, which can kill cockroaches that fall into the lower bucket 2. A limiting ring 3 is fixedly sleeved on the top outer side of the upper bucket 1. The end of the limiting ring 3 in cross-section is L-shaped, facilitating the worker to limit the position between the two limiting rings 3. Connecting rings 4 are symmetrically slidably connected to the inner side of the limiting rings 3. One end of each of the two connecting rings 4 contacts each other, enabling the trap to trap two cockroaches. The position between the connecting rings 4 is defined. A climbing plate 5 is fixedly connected to the top of the connecting ring 4. The top of the climbing plate 5 is at the same level as the top of the upper bucket 1, which makes it easy for cockroaches to crawl into the surface of the upper bucket 1. A limiting block 6 is fixedly installed on one side of the climbing plate 5. The limiting block 6 is snapped into the inside of the climbing plate 5, which can limit the position between the two climbing plates 5. A groove 7 is opened on the bottom edge of the climbing plate 5. A tapered tube 8 is embedded and fixedly installed in the middle of the top of the upper bucket 1, which facilitates the flow of cockroaches and also prevents them from falling into the lower bucket 2 and crawling out.
[0023] A support ring 9 is fixedly installed on the top inner side of the lower bucket 2, and a protective ring 10 is fixedly installed in the middle inner side of the upper bucket 1. The bottom end of the protective ring 10 contacts the top end of the support ring 9. Both the support ring 9 and the protective ring 10 are inclined to the horizontal plane, which can protect the bait stored on one side of the support ring 9. Ventilation holes 11 are equally spaced inside the support ring 9 and the protective ring 10 to facilitate the release of the bait's odor.
[0024] Push handles 12 are fixedly installed at equal intervals on the outer middle of both the upper bucket 1 and the lower bucket 2. A handle 13 is fixedly installed on the top of the upper bucket 1. Both the handle 13 and the push handle 12 are U-shaped. An anti-slip sleeve is fixedly fitted on the outer middle of the handle 13 to facilitate the movement of the upper bucket 1 by the staff. A drain pipe 14 is fixedly installed on the outer bottom of the lower bucket 2. A sealing plug 15 is squeezed and snapped onto one end of the drain pipe 14.
[0025] First, the staff places bait inside the lower bucket 2. The support ring 9, fixedly installed inside the lower bucket 2, supports the bait. Then, the staff moves the sealing plug 15 to seal the drain pipe 14, which is fixedly connected to the outside of the lower bucket 2. Next, the staff pours boric acid liquid into the lower bucket 2. After pouring, the staff holds the push handle 12 and rotates the upper bucket 1 and lower bucket 2. The upper bucket 1 is fixedly connected to the lower bucket 2 via a threaded connection. Then, the staff places the lower bucket 2 in a suitable position and moves the climbing plate 5 using the groove 7 at the bottom. During the movement of the climbing plate 5, a limiting block 6, fixedly installed on one side of the climbing plate 5, engages with the inside of the other climbing plate 5, limiting the position between the two climbing plates 5. Finally, the staff moves the two climbing plates 5, using the connection fixedly installed at the bottom edge of the climbing plates 5... Ring 4 slides inside the limiting ring 3 fixedly sleeved on the top of the outer side of the upper bucket 1, which can limit the movement direction of the climbing board 5, thereby completing the installation of the climbing board 5. The scent emitted by the bait stored inside the lower bucket 2 can attract cockroaches. The climbing board 5 makes it easy for cockroaches to climb to the surface of the upper bucket 1. The conical tube 8 fixedly installed inside the upper bucket 1 can guide the cockroaches, so that the cockroaches fall into the lower bucket 2. The inverted cone shape of the conical tube 8 can prevent the cockroaches that have entered the lower bucket 2 from climbing out. The boric acid liquid stored at the bottom inside the lower bucket 2 can kill the fallen cockroaches. After the cockroaches are killed, the staff opens the sealing plug 15, which allows the drain pipe 14 to discharge the boric acid liquid stored inside the lower bucket 2. After the boric acid liquid is discharged, the staff takes off the climbing board 5 and twists the upper bucket 1, so that the upper bucket 1 and the lower bucket 2 are separated, and the cockroach corpses stored inside the lower bucket 2 can be poured out.
[0026] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
