[0002] In the catering industry, cockroaches have become a significant hygiene problem. Their infestation not only seriously threatens food safety and customer experience but also poses a major challenge to store image and hygiene standards. In addition to internal hygiene management oversights and cockroaches introduced by items, the external sewage system serves as another critical pathway. Its complex and concealed nature provides cockroaches with an ideal breeding and invasion channel.

[0003] Many chemical agents on the market today work by volatilization. Since cockroaches are found in a wide range of areas inside sewers, the agents often cannot be applied evenly and comprehensively. The limited volatilization time of the agents makes it difficult for the repellent effect to last and create a long-term deterrent against cockroaches. Utility Model Content

[0013] Compared with the prior art, this utility model has the following advantages:

[0014] The present invention provides a device for repelling American cockroaches in sewers, comprising a housing and a water-absorbing module.

[0028] Example

[0029] This invention provides a device for repelling American cockroaches in sewers, addressing the problem that traditional chemical repellents have limited volatilization time, resulting in poor cockroach repellency. The device includes a housing 1 and a water-absorbing module 2, wherein:

[0030] like Figure 1-9 As shown, the box 1 has a receiving cavity 13. The box 1 provided in this embodiment is rectangular, but it can also be adjusted to a circle, ellipse, sphere or other irregular shape according to the actual application scenario to adapt to different spatial layouts. In use, the box 1 is placed under the sewer manhole cover. The box 1 is made of high-strength, corrosion-resistant materials, such as stainless steel, aluminum alloy or high-quality engineering plastics, to improve its service life under the sewer manhole cover. The outer wall of the box 1 is smooth and flat to facilitate cleaning and maintenance. A through hole 14 is provided on the outer wall of the box 1. The through hole 14 is connected to the receiving cavity 13 to allow air to circulate freely inside and outside the box 1. The shape of the through hole 14 can be arbitrary, and the number and size of the through holes 14 can be set according to the size of the box 1 and the usage requirements.

[0031] like Figure 9As shown, the water-absorbing module 2 is installed inside the receiving cavity 13. The water-absorbing module 2 is used to absorb the pesticide used to repel American cockroaches. The water-absorbing module 2 can be made of materials with water absorption and retention properties, such as fiber materials, porous ceramics, or sponges. In this way, the water-absorbing module 2 can not only effectively absorb and store the pesticide, but also, when the box 1 is placed under the sewer manhole cover, the pesticide inside the water-absorbing module 2 will gradually evaporate or slowly release into the receiving cavity 13. Then, the pesticide vapor or droplets will naturally diffuse out of the box 1 through the through-hole 14, thereby repelling the cockroaches. To prevent American cockroaches from moving towards the vicinity of the enclosure 1, thereby reducing the chance of pests such as American cockroaches entering the manhole cover through the sewer cover. In addition, the diffusion speed of the pesticide can be accelerated by installing a fan near the through hole 14 or by utilizing natural convection. In order to maintain the continuous diffusion effect of the pesticide inside and outside the enclosure 1, the pesticide can be replenished to the water absorption module 2 regularly, or the water absorption module 2 that absorbs the pesticide can be replaced with a new one. At the same time, it is also necessary to check the unobstructed state of the through hole 14 to prevent the through hole 14 from becoming blocked and affecting the normal diffusion of the pesticide.

[0032] With the above structure, the device for repelling American cockroaches in sewers provided by this utility model first allows the water-absorbing module 2 to absorb the repellent solution for American cockroaches. Then, the water-absorbing module 2 is placed in the receiving cavity 13, and the box 1 is placed under the sewer manhole cover. The agent absorbed by the water-absorbing module 2 diffuses out of the box 1 through the through hole 14, thereby repelling American cockroaches from crawling out of the sewer manhole cover. Therefore, this device for repelling American cockroaches in sewers uses a water-absorbing module 2 to absorb the pesticide, releasing it slowly and extending the evaporation time to maintain a continuous repellent effect. The through holes 14 on the housing 1 reduce the rapid evaporation of the pesticide, thus reducing the need for frequent replacement or re-spraying and minimizing operation frequency. When the pesticide in the sponge is depleted, a new water-absorbing module 2 can be replaced or the pesticide can be refilled into it, thereby continuously repelling American cockroaches in sewers, extending the repellency time, and improving the repellency effect.

[0033] An optional implementation method of this embodiment is as follows: Figure 1-9As shown, the housing 1 includes a first sub-box 11 and a second sub-box 12. The first sub-box 11 has a semi-enclosed first sub-cavity 131 for accommodating the water-absorbing module 2. The second sub-box 12 matches the first sub-box 11, and both have an opening on their opposite sides. The openings of the first sub-box 11 and the second sub-box 12 are respectively connected to the first sub-cavity 131 and the second sub-cavity 132. When the opposite sides of the first sub-box 11 and the second sub-box 12 abut, the first sub-cavity 131 and the second sub-cavity 132 form a receiving cavity 13. The first sub-box 11 and the second sub-box 12 can be opened and closed to allow the water-absorbing module 2 to be placed into the first sub-cavity 131 and the second sub-cavity 132 through the openings. A sealing strip can be provided on the abutting side of the first sub-box 11 and the second sub-box 12 to reduce the flow of medicine through the gap between the first sub-box 11 and the second sub-box 12 to the outside of the housing 1, thereby reducing the diffusion time of the medicine. Figure 10 As shown, another embodiment of this invention can be provided with multiple partitions 7 in the first sub-cavity 131 and the second sub-cavity 132, with the water-absorbing module 2 placed inside the partitions 7. The partitions 7 divide the first sub-cavity 131 and the second sub-cavity 132 into multiple sub-chambers 71. Each sub-chamber 71 contains a water-absorbing module 2, and each sub-chamber 71 is provided with a through hole 14 that connects to the outside of the box body 1. Each sub-chamber 71 can diffuse the pesticide to the outside of the box body 1 through the through hole 14. This reduces the accumulation of pesticide at the bottom of the water-absorbing module 2 under the action of gravity, thereby reducing the pesticide diffusion effect above the box body 1 and thus reducing the repellency effect on American cockroaches. At the same time, the water-absorbing module 2 of each sub-chamber 71 can be used to absorb different pesticides to achieve the effect of repelling different pests. It is worth noting that when the water-absorbing module 2 of each sub-chamber 71 absorbs different pesticides, it is necessary to consider whether the diffusion and mixing of different pesticides will produce other substances that are harmful to the human body, or whether the diffusion and mixing of different pesticides will cause the pesticide to become ineffective.

[0034] An optional implementation method of this embodiment is as follows: Figure 2-4As shown, to facilitate the opening and closing of the housing 1, the device for repelling American cockroaches in sewers also includes a rotating part 3. One end of the rotating part 3 is installed on one side edge of the first sub-housing 11 by means of screws, rivets, or welding, and the other end is installed on one side edge of the second sub-housing 12. The rotating part 3 can be a single shaft or a hinge or other structure, so that the first sub-housing 11 and the second sub-housing 12 can be opened and closed by rotating along the axial direction of the rotating part 3. Specifically, when the user needs to open the housing 1, the first sub-housing 11 and the second sub-housing 12 apply opposite forces, so that the first sub-housing 11 and the second sub-housing 12 rotate relative to each other about the rotating part 3, thereby opening the housing 1 and exposing the receiving cavity 13, so as to replace the water absorption module 2 or add agents to the water absorption module 2. When the user needs to close the housing 1, he only needs to rotate the first sub-housing 11 and the second sub-housing 12 towards each other and push them together until the opposite sides of the first sub-housing 11 and the second sub-housing 12 abut against each other to form the housing 1.

[0035] An optional implementation of this embodiment is as follows: It further includes a locking fastener 4 and a locking movable part 5. The locking fastener 4 is installed on the side of the first sub-box 11. The locking fastener 4 is a locking groove, a snap-fit, or other form of locking mechanism, used to receive and fix the locking movable part 5 when locked. The locking movable part 5 is installed on the second sub-box 12, and its position should match the locking fastener 4. The locking movable part 5 is inserted into the locking fastener 4 to lock the first sub-box 11 and the second sub-box 12 securely and prevent them from falling off. The locking movable part 5 is used to form an effective locking connection with the locking fastener 4. In one implementation of this embodiment, the first sub-box 11 and the second sub-box 12 are fixed by a padlock. When it is necessary to fix the first sub-box 11 and the second sub-box 12... When sub-box 12 is in operation, the first sub-box 11 and the second sub-box 12 are rotated to bring them into contact. The locking movable part 5 is inserted into the locking fixing part 4 to fix the first sub-box 11 and the second sub-box 12 together, preventing the first sub-box 11 and the second sub-box 12 from rotating along the axial direction of the rotating part 3. When it is necessary to open the first sub-box 11 and the second sub-box 12, the locking connection between the locking fixing part 4 and the locking movable part 5 is released, and the second sub-box 12 and the first sub-box 11 are rotated along the rotating part 3, thereby opening the first sub-box 11 and the second sub-box 12. The cooperation between the locking fixing part 4 and the movable part effectively prevents the first sub-box 11 and the second sub-box 12 from being accidentally opened in the closed state, enhancing the overall stability of the device.

[0036] An optional implementation method of this embodiment is as follows: Figure 1-2 and Figure 5-6As shown, to facilitate the fixing of the housing 1, the device for repelling American cockroaches in sewers also includes a lug 6. The lug 6 is installed on the top of the housing 1. Specifically, the lug 6 can be flexibly installed on the top of the first sub-box 11 or the second sub-box 12. The lug 6 can be made of the same material as the housing 1, so as to facilitate the installation of the lug 6 on the housing 1 by integral molding or bolting. The lug 6 has a through hole 61 for screws, ropes or other fasteners to pass through, thereby connecting the housing 1 to the sewer cover or drain. The box 1 is connected to the sewer wall. Specifically, when it is necessary to fix the box 1 under the sewer cover, screws can be used to connect the lug 6 to the reserved hole on the cover or the hole drilled in the sewer to ensure that the box 1 is stable and does not shake. Alternatively, ropes or other tieable objects can be passed through the through hole 61 to tie or suspend the box 1 to the edge of the cover or the appropriate position on the inner wall of the sewer. The lug 6 improves the convenience and flexibility of the box 1 installation and enhances the stability of the box 1 during use, which provides convenience for subsequent maintenance and replacement work.

[0037] An optional implementation of this embodiment is as follows: it also includes a bolt 8, one end of which passes through the through hole 61 to fix the box 1. After the one end of the bolt 8 passes through the through hole 61 of the lug 6, a tightening force can be applied by rotating the nut, thereby firmly fixing the box 1 in the predetermined position. The cooperation between the bolt 8 and the nut can provide a strong tightening force to ensure that the box 1 can be fixed stably in harsh environments. The bolt 8 and the nut and other fasteners can be reused, which is convenient for disassembly and reinstallation, thereby facilitating the cleaning and maintenance of the box 1.

[0038] An optional implementation of this embodiment is as follows: The rotating part 3 is a hinge, which is installed on the side edge or top edge of the first sub-box 11 and the second sub-box 12 to ensure stability and smoothness during rotation. When it is necessary to open the box 1, the first sub-box 11 and the second sub-box 12 are rotated in the opposite direction, so that the first sub-box 11 and the second sub-box 12 rotate relative to each other about the hinge as the axis. The included angle between the first sub-box 11 and the second sub-box 12 gradually increases until it is fully opened, opening the receiving cavity 13 to facilitate the removal and placement of the water absorption module 2 or the addition of medicine to the water absorption module 2. When it is necessary to close the box 1, the first sub-box 11 and the second sub-box 12 rotate towards each other and push together until the opposite sides of the first sub-box 11 and the second sub-box 12 abut against each other to form the box 1.

[0039] An optional implementation of this embodiment is as follows: the water absorption module 2 is a PVA sponge. The PVA sponge has excellent water absorption and retention properties, and can quickly absorb and lock in a large amount of medicine. At the same time, the medicine can slowly diffuse to the outside of the box 1 through the through hole 14, thereby repelling the American cockroach.

[0040] In summary, the device for repelling American cockroaches in sewers provided by this utility model, when in use, firstly, opposing forces are applied to the first sub-box 11 and the second sub-box 12, causing the first sub-box 11 and the second sub-box 12 to rotate relative to each other around the rotating part 3, thereby opening the box body 1 and allowing the water-absorbing module 2 to absorb the American cockroach repellent solution. Then, the water-absorbing module 2, which absorbs the American cockroach repellent solution, is placed in the receiving cavity 13, and the first sub-box 11 and the second sub-box 12 are rotated towards each other and pushed together. The opposite sides abut against each other to form a box 1. The locking movable part 5 is inserted into the locking fixed part 4. The locking movable part 5 is used to form an effective locking connection with the locking fixed part 4 to lock the first sub-box 11 and the second sub-box 12 to keep them stable and not fall off. One end of the bolt 8 passes through the through hole 61 of the lug 6. The tightening force is applied by rotating the nut, thereby firmly fixing the box 1 to the predetermined position under the sewer manhole cover. The agent adsorbed by the water absorption module 2 diffuses out of the box 1 through the through hole 14, thereby repelling American cockroaches from crawling out of the sewer manhole cover. Therefore, this device for repelling American cockroaches in sewers uses a water-absorbing module 2 to absorb and store the pesticide. Simultaneously, when the housing 1 is placed under the sewer manhole cover, the pesticide in the water-absorbing module 2 gradually evaporates or is slowly released into the receiving cavity 13, thus extending the continuous evaporation time. The pesticide vapor or droplets naturally diffuse outside the housing 1 through the through-hole 14, continuously repelling American cockroaches from moving towards the vicinity of the housing 1. This reduces the likelihood of pests like American cockroaches entering the manhole through the sewer manhole cover. The through-hole 14 on the housing 1 reduces the rapid evaporation of the pesticide, minimizing the need for frequent pesticide replacement or re-spraying, and reducing the operational frequency. When the pesticide in the sponge is depleted, a new water-absorbing module 2 can be replaced or the pesticide can be re-injected into the water-absorbing module 2, thus continuously repelling American cockroaches in sewers, extending the repellency time, and ultimately improving the repellency effect.

[0041] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope described in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
