Description

Technical Field

[0001] This utility model relates to a disinfection and vector control device for public restrooms, belonging to the field of vector control technology. Background Technology

[0002] Public restrooms are high-risk areas for the spread of infectious diseases. Their damp environment and frequent lack of ventilation provide favorable conditions for the survival and reproduction of pathogenic microorganisms such as E. coli and Salmonella. At the same time, the high humidity attracts disease-carrying organisms such as mosquitoes and flies, which not only play a crucial role in the food chain but also directly impact public health. These vectors can carry pathogens and spread them to wider areas, leading to the spread of infectious diseases and seriously threatening public health. This is especially true for vector-borne infectious diseases transmitted by insects such as mosquitoes and flies. Because vector-borne transmission is rapid and can easily cause widespread epidemics, once mosquitoes and flies breed in public restrooms and similar places, they become the source of disease spread. Pathogenic microorganisms spread to other areas through air, food, and water, posing a health threat to the population. When disease-carrying organisms come into contact with large numbers of germs in public restrooms, they can carry these bacteria, viruses, and other pathogens, further exacerbating the spread of pathogens.

[0003] To reduce the spread of disease vectors and control the diffusion of pathogens, traditional pest control methods typically involve periodically spraying pesticides or applying insecticides. While these methods can kill disease vectors and reduce their numbers to some extent, they still have limitations. These traditional methods cannot sustainably prevent the activity of insect-borne vectors such as mosquitoes and flies. Furthermore, although pesticide spraying can effectively kill some disease vectors, some pathogens can form aerosols suspended in tiny droplets or solid particles. These aerosols can float in the air for extended periods, and without air disinfection, they can spread pathogens through the air in enclosed spaces.

[0004] Therefore, in order to improve the disinfection and vector control effects in high-risk areas such as public restrooms, a device is designed that can both disinfect the air in public restrooms and control the vector organisms within them. Summary of the Invention

[0036] In order to make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0037] like Figures 1-3As shown, this disinfection and vector control equipment for public restrooms is mainly used in public restrooms and other places where vector-borne organisms are prone to breed. In use, the equipment is fixed to the ceiling or wall of the public restroom above human height using the hanging lugs 5 at the top of the housing 1, preventing the light from the internal insect-attracting lamp 303 from shining on people. Depending on the size of the space and the coverage area of ​​the spray, multiple units can be used together to comprehensively cover the public restroom area. This equipment includes a housing 1, a liquid spray module 2, and an integrated mosquito-killing filter module 3.

[0038] like Figure 1 As shown, the shell 1 consists of a lower killing chamber 101 and an upper liquid storage chamber 102. The killing chamber 101 has an induction opening 103 on its side to guide disease vectors into the chamber. A removable tray 4 is fixed to the bottom of the killing chamber 101 by screws. A conical platform 401 is fixed to the middle of the removable tray 4. A hollow hole 402 is formed on the upper surface of the conical platform 401, and a ventilation slit 403 is formed on the conical surface of the platform 401 to prevent disease vectors from passing through. An installation channel hole 104 penetrating the liquid storage chamber 102 is formed at the top of the shell 1. The conical platform 401 guides the remains of disease vectors killed by electrocution to the periphery of the removable tray 4, preventing blockage of the ventilation slit 403 for air intake of the air filter cartridge 305.

[0039] like Figure 1 As shown, the liquid spray module 2 includes a water pump built into the bottom of the liquid storage chamber 102, and an atomizing nozzle connected to the water outlet of the water pump. The atomizing nozzle is fixed to the top of the killing chamber 101.

[0040] The storage chamber 102 stores disinfectant, insecticide, and other media. Activating the water pump draws these media out and sprays them through atomizing nozzles to disinfect pathogens that enter the disinfection chamber. The water pump can be started periodically or continuously as needed for disinfection.

[0041] like Figures 1-3As shown, the integrated mosquito-killing filter module 3 includes a cylindrical body 301 fixed inside the installation channel hole 104. The cylindrical body 301 is made of insulating plastic. A fan 302 is fixed to the upper inner cavity of the cylindrical body 301. An insect-attracting lamp 303 is evenly surrounding the lower outer circumference of the cylindrical body 301. The insect-attracting lamp 303 is a fluorescent tube that emits ultraviolet light with a wavelength in the range of 315-400nm. A high-voltage electric shock net 304 is fitted around the outer circumference of the insect-attracting lamp 303. The high-voltage electric shock net 304 uses a high voltage in the range of 800-3000 volts and a current less than or equal to 1 mA. An air filter cartridge 305 with its air inlet facing downwards is also fixed inside the cylindrical body 301. The air inlet of the air filter cartridge 305 is sealed to the hollow hole 402 on the upper surface of the conical platform 401. An ultraviolet disinfection lamp tube 306 is installed inside the air filter cartridge 305. The integrated mosquito-killing filter module 3 is inserted into the installation channel hole 104, and the top is sealed and fixed by screws and rubber rings.

[0042] The insect-attracting lamp 303 is positioned directly opposite the induction opening 103, luring disease-carrying organisms such as mosquitoes and flies into the disinfection chamber. Some mosquitoes and flies collide with the high-voltage electric shock net 304 and are killed by its high voltage. Other insects are eliminated by the pesticide spray module 2.

[0043] When disease-carrying organisms are killed by the high-voltage electric shock net 304, they produce aerosols carrying pathogens. The fan 302 continues to operate, using the integrated mosquito-killing filter module 3 to draw in and filter the surrounding air, drawing potentially pathogen-containing aerosols into the air filter cartridge 305. The air filter cartridge 305 can use a HEPA filter or a HEPA + activated carbon composite filter, effectively removing aerosol pollutants such as bacteria, viruses, and dust from the air. Furthermore, the ultraviolet disinfection lamp 306 inside the air filter cartridge 305 can kill both the air and pathogens adhering to the inner surface of the air filter cartridge 305, further enhancing disinfection capabilities.

[0044] This device integrates the elimination and disinfection of disease vectors into a single unit, enabling not only the elimination of disease vectors but also the disinfection of their carcasses. Its modular design allows for more efficient elimination through the coordinated use of multiple modules. However, when air filtration and high-voltage electric shock functions are not required, the integrated mosquito-killing filter module 3 can be removed to save on equipment costs. The installation channel hole 104 can then be closed, allowing the UV lamp to attract disease vectors while the pesticide spray module 2 continues to eliminate them.

[0045] The detachable tray 4 structure not only facilitates the regular cleaning of disease vector carcasses, but also makes it easy to clean the high-voltage electric shock net 304, the ultraviolet disinfection lamp tube 306, and replace the air filter cartridge 305.

[0046] like Figure 1As shown, in some embodiments, a conical bucket 105 with a larger outer opening and a smaller inner opening is installed inside the induction opening 103.

[0047] After attracting mosquitoes by means of insect-attracting lamps 303, the shape of the cone-shaped bucket 105 can guide the mosquitoes inward along the cone-shaped slope and into the shell 1, thus collecting the mosquitoes. The structure of the cone-shaped bucket 105 makes it difficult for mosquitoes to find an exit, increasing the difficulty for mosquitoes to escape, thereby improving the capture efficiency of disease vectors.

[0048] Under the suction of the fan 302, the conical bucket 105 can cooperate with the airflow generated by the fan 302 to guide the airflow to blow the mosquitoes smoothly into the disinfection area inside the shell 1. The airflow flows along the inner wall of the conical bucket 105, carrying the attracted mosquitoes into the disinfection cavity.

[0049] In some embodiments, the conical hopper 105 is provided with uniformly spaced slits 106 that prevent disease vectors from passing through.

[0050] The narrow slit 106 allows air to enter and create a wider airflow, which is beneficial for capturing mosquitoes.

[0051] In some embodiments, the conical bucket 105 is a transparent conical bucket 105.

[0052] The transparent cone-shaped container 105 facilitates the propagation of the insect-attracting lamp 303, attracting more disease-carrying organisms into the shell 1 and improving capture efficiency.

[0053] like Figure 1 As shown, in some embodiments, a positioning sleeve 404 is fixed on the upper surface of the conical platform 401 of the detachable tray 4, surrounding the hollow hole 402. The inner diameter of the positioning sleeve 404 is the same as the outer diameter of the bottom of the cylinder 301. When the cylinder 301 is installed in the mounting channel hole 104, the bottom of the cylinder 301 is just inserted into the positioning sleeve 404.

[0054] The positioning sleeve 404 structure facilitates the bottom positioning of the integrated mosquito-killing filter module 3, and makes it convenient and accurate to seal and connect the air inlet of the air filter cartridge 305 with the hollow hole 402 on the upper surface of the conical platform 401.

[0055] In some embodiments, a sealing rubber ring is provided at the air inlet end of the air filter cartridge 305, and the air inlet end of the air filter cartridge 305 is tightly abutted against the upper surface of the conical platform 401 through the sealing rubber ring to achieve a sealed connection with the hollow hole 402.

[0056] It achieves a seal by using a sealing rubber ring and a tight fit, allowing for quick installation and disassembly.

[0057] like Figure 1As shown, in some embodiments, a fixing plate 307 is provided around the upper outer circumference of the cylinder 301, and the cylinder is fixed to the top of the housing 1 by screwing the fixing plate 307 and the rubber ring. In this case, the air inlet end of the air filter cylinder 305 is tightly pressed against the upper surface of the conical platform 401. The outer diameters of the upper and lower parts of the integrated mosquito-killing filter module 3 are the same, which facilitates the passage through the installation channel hole 104.

[0058] The outer diameter of the fixing plate 307 is larger than that of the mounting channel hole 104, which can limit the upper part of the cylinder 301 to the top of the shell 1 and complete the fixed installation.

[0059] like Figure 1 As shown, in some embodiments, the liquid storage chamber 102 is divided into an upper liquid storage chamber 107 and a lower liquid storage chamber 108. The water pump includes a first water pump 202 and a second water pump 205, and the atomizing nozzle includes a first atomizing nozzle 203 and a second atomizing nozzle 206. The upper liquid storage chamber 107 has a covered first injection channel 201 at its top, and the first water pump 202 is installed at its bottom. The water outlet of the first water pump 202 is connected to the first atomizing nozzle fixed at the top of the killing chamber 101. The nozzle 203 is connected, and the top of the lower liquid storage chamber 108 is provided with a covered second liquid injection channel 204 that passes through the upper liquid storage chamber 107. A second water pump 205 is installed at the bottom of the lower liquid storage chamber 108, and the outlet end of the second water pump 205 is connected to a second atomizing nozzle 206 fixed at the top of the killing chamber 101. The upper liquid storage chamber 107 and the lower liquid storage chamber 108 store different liquid media, for example, the upper liquid storage chamber 107 stores disinfectant, and the lower liquid storage chamber 108 stores killing liquid. Among them, the disinfectant can be a chlorine-containing disinfectant, and the killing liquid can be a pyrethroid killing liquid.

[0060] The water pumps also include a third water pump 207 and a fourth water pump 209, and the atomizing nozzles include a third atomizing nozzle 208 and a fourth atomizing nozzle 210. A human body sensor 211 is installed on the bottom outer side of the detachable tray 4. The human body sensor 211 adopts a commercially available millimeter-wave + infrared dual-mode sensor, which can not only sense moving human bodies, but also supports static sensing. The third water pump 207 is installed at the bottom of the upper liquid storage chamber 107, and the water outlet of the third water pump 207 is connected to the third atomizing nozzle 208 fixed on the bottom outer side of the detachable tray 4. The fourth water pump 209 is installed at the bottom of the lower liquid storage chamber 108, and the water outlet of the fourth water pump 209 is connected to the fourth atomizing nozzle 210 fixed on the bottom outer side of the detachable tray 4. The third atomizing nozzle 208, the fourth atomizing nozzle 210, and the third atomizing nozzle 208 and the fourth water pump 209 are connected by water pipes with quick-connect couplings for easy disassembly and installation.

[0061] The upper liquid storage chamber 107 and the lower liquid storage chamber 108 respectively store disinfectant or insecticide. The insecticide spray kills disease-carrying organisms, while the disinfectant spray disinfects the internal air and the dead disease-carrying organisms, enabling a more comprehensive disinfection process and improving efficiency. Furthermore, the third atomizing nozzle 208 and the fourth atomizing nozzle 210 located externally at the bottom of the casing 1 can also kill disease-carrying organisms in the surrounding environment and disinfect the environment.

[0062] The third atomizing nozzle 208 and the fourth atomizing nozzle 210 both use commercially available rotary sprayers, which rely on the high-speed liquid ejected from the nozzle to achieve their own rotating spray.

[0063] like Figure 4 As shown, this device can automate the killing and disinfection process through a controller.

[0064] Specifically, the controller electrically connects the first water pump 202, the second water pump 205, the third water pump 207, the fourth water pump 209, and the human body sensor 211. When a person is detected near the equipment, the spraying of disinfectant and insecticide is stopped; when no one is detected near the equipment, insecticide and disinfectant spraying is performed.

[0065] The working principle is as follows:

[0066] The human body sensor 211 detects whether there are people near the equipment and transmits the signal to the controller; the controller then controls the first water pump 202, the second water pump 205, the third water pump 207, and the fourth water pump 209 to automatically spray.

[0067] (1) When the human body sensor 211 detects that no one is near the device, it automatically sprays at preset intervals. For example, it sprays once every 10 minutes, and each spray lasts for 5 seconds.

[0068] (2) When the human body sensor 211 detects that there are people near the equipment, even if the preset interval time point is reached, the spraying will not be carried out, that is, the spraying will be abandoned and the people will be protected. The system will wait for the next time point and then determine whether there are people based on the signal fed back to the controller by the human body sensor 211: if there are no people, spraying will start according to step (1); if there are people, the system will continue to wait for the next time point to be determined according to step (2).

[0069] In places with low population density, the above steps are sufficient for automated disinfection. However, in high-traffic areas, where people are constantly moving around during the day, the automatic disinfection process may remain stopped, only operating at night when fewer people are around. Therefore, an additional warning device (not shown in the diagram) electrically connected to the controller can be added. This warning device, installed outside housing 1, can provide voice and light alerts at preset times, for example, once per hour, with each spray lasting 30 seconds. Before each activation, the warning device broadcasts to nearby personnel: "30 seconds of disinfection is coming; please wait before entering." It then maintains a flashing red light before forced spraying. These measures can compensate for the inconvenience of continuous disinfection in densely populated areas.

[0070] Automated spraying can replace manual disinfection, requiring only daily replenishment of disinfectant solution to the storage chamber 102 by maintenance personnel. This improves disinfection efficiency and enhances its sustainability.

[0071] like Figure 1 As shown, in some embodiments, the ultraviolet disinfection lamp 306 is fixed to the removable tray 4, and the ultraviolet disinfection lamp 306 is connected to the power supply through the wire of the quick-connect connector. After the removable tray 4 is removed, the quick-connect connector is loosened so that the removable tray 4 is completely separated from the housing 1; before installing the removable tray 4, the quick-connect connector is connected first, and then the mounting screws of the removable tray 4 are installed.

[0072] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
