Description

Technical Field

[0001] This utility model belongs to the field of exhaust fan technology, specifically a mosquito-attracting exhaust fan. Background Technology

[0002] An exhaust fan is a device that uses mechanical drive to exchange indoor and outdoor air. It is widely used in homes, businesses, and industries. Its main functions include removing stale air, regulating humidity, lowering temperature, and improving air quality.

[0003] With the improvement of living standards, people are paying more and more attention to food safety. In food production workshops, mosquito control is one of the core links in ensuring food safety. Its importance not only involves regulatory compliance, but also directly relates to product quality, consumer health, and corporate reputation. Mosquitoes (and other flying insects) carry pathogenic microorganisms such as Salmonella, Escherichia coli, and Shigella, which can be transmitted through contact with food or equipment, posing a serious threat to food safety.

[0004] Currently, mosquito control in the workshop mainly relies on physical methods: installing double doors, air curtains, and screens around the workshop, and covering drainage ditches with insect-proof netting. However, these traditional measures cannot completely prevent mosquitoes from entering, posing a certain risk to food safety. Utility Model Content

[0005] To address the issue that traditional mosquito control methods in food production workshops cannot completely prevent mosquitoes from entering, thus posing a certain risk to food safety, this utility model provides a mosquito-attracting exhaust fan.

[0006] This utility model is achieved through the following technical solution: A mosquito-attracting exhaust fan includes an exhaust pipe that can be installed at the exhaust port. A fan is rotatably installed inside the exhaust pipe. A mosquito-attracting lamp is provided on the side of the fan near the air intake end, which can attract mosquitoes. A guide cover is provided on the side of the fan near the exhaust end, which is connected to the inner wall of the exhaust pipe. The guide cover is tapered along the exhaust direction. An electric killing net is connected and installed on the side of the exhaust pipe near the exhaust end, which is located at the air outlet of the guide cover. The electric killing net is used to kill mosquitoes with high voltage.

[0007] A further improvement of this utility model is that an outer cylinder is connected to the exhaust end of the exhaust pipe; a circular mesh frame is provided on the outside of the electric extinguishing net, and a number of mounting rods connected to the outer cylinder are arranged in a circular array on the outside of the mesh frame.

[0008] A further improvement of this utility model is that the outer cylinder has several through holes through which the end of the mounting rod away from the mesh frame can pass, and the end of the mounting rod away from the mesh frame is threaded with a mounting nut that can abut against the outside of the outer cylinder.

[0009] A further improvement of this utility model is that the outer cylinder size is smaller than the exhaust pipe size, and the end of the mounting rod away from the mesh frame does not protrude from the outer surface of the exhaust pipe.

[0010] A further improvement of this utility model is that a through hole is provided on the lower side of the outer cylinder, and a connecting cylinder is connected and installed thereon. A collection can for collecting mosquitoes is detachably connected and installed at the lower end of the connecting cylinder.

[0011] A further improvement of this utility model is that a protective net is connected and installed at the end of the outer cylinder away from the exhaust pipe.

[0012] A further improvement of this utility model is that a number of protective net mounting blocks capable of positioning and installing the protective net are fixedly connected to the end of the inner side wall of the outer cylinder away from the exhaust pipe.

[0013] A further improvement of this utility model is that a fixing plate is connected and installed on the outer side of the exhaust pipe's suction end, and the fixing plate has several fixing holes.

[0014] A further improvement of this utility model is that a positioning protrusion is fixedly connected and installed on the upper part of the outer side of the exhaust pipe near the fixed plate.

[0015] A further improvement of this utility model is that a horn-shaped inner cylinder is connected and installed at the air intake end of the exhaust pipe.

[0016] As can be seen from the above technical solutions, the beneficial effects of this utility model are: In use, install this device inside the room's exhaust vent, with the mosquito-attracting lamp facing inwards. The fan, when powered on, generates an outward airflow, providing basic functions such as removing stale air, regulating humidity, lowering temperature, and improving air quality. The electric killing grid is also powered on and operational. The mosquito-attracting lamp actively lures mosquitoes into the room. When mosquitoes fly towards the lamp, they are sucked into the exhaust pipe by the fan's suction. The airflow is accelerated by a tapering guide, ensuring the mosquitoes are reliably and accurately sprayed onto the electric killing grid for elimination. The overall structure is simple, adding active mosquito attraction and elimination functions to the basic functions of an exhaust fan without changing the overall size. It is easy to install and effectively achieves thorough mosquito eradication, ensuring food safety. Attached Figure Description

[0023] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0024] like Figure 1-4 As shown, this utility model discloses a mosquito-attracting exhaust fan, including a cylindrical exhaust pipe 1 that can be fixedly installed at the exhaust port (circular, generally located on the upper part of the wall) of a room (such as a food processing workshop). A fan 2 is rotatably installed inside the exhaust pipe 1. A mosquito-attracting lamp 3 (emitting ultraviolet light with a wavelength of 360-380 nanometers, combined with a micro-temperature effect to simulate the carbon dioxide gas and heat radiation released by the human body, attracting mosquitoes to approach) is provided on the side (outer side) of the fan 2 near the exhaust end. The guide cover 15 is connected to the inner wall of the exhaust pipe 1. The guide cover 15 is gradually tapered along the exhaust direction (from the inside to the outside). An electric killing net 6 is connected and installed on the side (outer side) of the exhaust pipe 1 near the exhaust end. The electric killing net 6 is used to kill mosquitoes with high voltage.

[0025] In use, install this device inside the room's exhaust vent, with the mosquito-attracting lamp 3 facing inwards. The fan 2 is powered on and rotates, generating an outward airflow to provide basic functions such as removing polluted air, regulating humidity, lowering temperature, and improving air quality. The electric killing net 6 is powered on and in working condition. The mosquito-attracting lamp 3 actively attracts mosquitoes in the room. When mosquitoes fly towards the lamp 3, they are sucked into the exhaust pipe 1 by the suction generated by the fan 2. The airflow is accelerated by the tapering guide shroud 15 (along the exhaust direction), ensuring that the mosquitoes are reliably and accurately sprayed onto the electric killing net 6 for elimination. The overall structure is simple, adding active mosquito attraction and elimination functions to the basic functions of an exhaust fan without changing the overall size. It is easy to install and effectively achieves thorough elimination of mosquitoes, ensuring food safety.

[0026] The exhaust pipe 1 has a fixing plate 13 vertically connected to the outer side of the suction end, and the fixing plate 13 has several fixing holes 14. Through the fixing holes 14, bolts, screws and other connectors can be used to securely install the exhaust fan at the exhaust hole (inner side of the wall), making the installation of the exhaust fan more convenient and secure, ensuring that it will not shift during operation, and thus stably achieving the functions of attracting mosquitoes and exhausting air.

[0027] Furthermore, a positioning protrusion 16 is fixedly connected to the upper outer side of the exhaust pipe 1 near the fixing plate 13 (inner end), and the outer end of the positioning protrusion 16 is chamfered. During installation, a notch can be made in the upper part (inner end) of the inner wall of the exhaust hole of the wall to position and engage the positioning protrusion 16. By cooperating with the notch, the positioning protrusion 16 can assist the exhaust fan in being quickly and accurately positioned during installation, ensuring the uniqueness of the installation direction of the entire exhaust fan (so that the positioning protrusion 16 faces the same direction), which provides convenience for subsequent mosquito collection; the chamfered design makes the positioning protrusion 16 easier to insert into the notch, playing a guiding role and improving installation efficiency and convenience.

[0028] In a further embodiment, a horn-shaped inner cylinder 11 is connected and installed at the air intake end (inner end) of the exhaust pipe 1. The horn-shaped structure can increase the air intake area, allowing the exhaust fan to draw in air more effectively when it is working, thereby improving the exhaust efficiency; at the same time, the larger air intake area also helps to attract more mosquitoes that are close to the mosquito-attracting lamp 3 into the exhaust pipe 1, thus improving the mosquito-attracting effect.

[0029] In a further embodiment, an outer cylinder 12 is connected to the exhaust end (outer end) of the exhaust pipe 1; a circular mesh frame is provided on the outer side of the electric insecticidal net 6, and four mounting rods 61 connected to the outer cylinder 12 are arranged in a circular array on the outer side of the mesh frame. The electric insecticidal net 6 is connected to the outer cylinder 12 by the circular array of mounting rods 61, making the installation of the electric insecticidal net 6 more stable and ensuring its stable position during operation (the size of the electric insecticidal net 6 is larger than the size of the outlet end of the guide cover 15, and the two have a certain gap and are coaxially set), effectively exerting the function of high-voltage electric insecticidal killing; and a certain vibration is generated during the rotation of the fan 2, which is transmitted to the electric insecticidal net 6 through the mounting rods 61, which helps the mosquitoes attached to the electric insecticidal net 6 to fall off, ensuring the effectiveness of the electric insecticidal net 6.

[0030] Furthermore, the outer cylinder 12 has several through holes through which the end of the mounting rod 61 away from the mesh frame (outer end) can pass. The end of the mounting rod 61 away from the mesh frame is threaded with a mounting nut 62 that abuts against the outer side (radially) of the outer cylinder 12. By tightening the mounting nut 62, the mounting rod 61 can be firmly fixed to the outer cylinder 12, thereby further enhancing the stability of the electric killing net 6 installation and ensuring that the electric killing net 6 will not loosen or shift during operation, stably achieving the high-voltage electric killing function for mosquitoes. In addition, by rotating the mounting nut 62, the tension of the mounting rod 61 can be adjusted, thereby flexibly adjusting the vibration amplitude of the electric killing net 6 to reliably shake off attached mosquitoes. The mounting rod 61 has a certain degree of elasticity, facilitating the disassembly, assembly, and maintenance of the electric killing net 6.

[0031] Furthermore, the outer cylinder 12 is smaller than the exhaust pipe 1, and the end of the mounting rod 61 furthest from the mesh frame (the outer end) does not protrude from the outer surface of the exhaust pipe 1. The smaller outer cylinder 12 can serve as a guide during installation (inserting into the exhaust hole on the wall from the inside out), making installation convenient; in addition, it provides space for the mounting nut 62 and the outer end of the mounting rod 61, avoiding interference with the exhaust hole on the wall during disassembly and assembly.

[0032] The outer cylinder 12 has a through hole 17 on its lower side, and a funnel-shaped connecting cylinder 5 is connected to it. The lower end of the connecting cylinder 5 is detachably connected to a collection container 4 for collecting mosquitoes (connected by a threaded fitting). The through hole 17 has a rectangular projection, is located directly below the electric insecticidal net 6, and its projected length is not less than the size of the electric insecticidal net 6. The mosquitoes that have been killed and fallen can accurately pass through the through hole 17 and the connecting cylinder 5 into the collection container 4 for collection, preventing dead mosquitoes from scattering everywhere and keeping the environment clean. The collection container 4 is detachable, making it easy to clean the collected mosquitoes regularly.

[0033] In another embodiment of this utility model, a steel protective net 7 is connected and installed at the end of the outer cylinder 12 away from the exhaust pipe 1 (outer end). This can prevent foreign objects from entering the exhaust fan, avoid damage to components such as the electric killing net 6 and the fan 2, ensure the stable operation of the mosquito-attracting exhaust fan, extend its service life, and at the same time prevent the human body from contacting the internal electrified or moving parts, thus improving the safety of use.

[0034] Furthermore, several protective net mounting blocks 18 are fixedly connected to the inner wall of the outer cylinder 12 at the end (outer end) away from the exhaust pipe 1, which can position and install the protective net 7. The protective net 7 is detachably connected to the protective net mounting blocks 18 by screws. This facilitates the disassembly and installation of the protective net 7, makes it easy to replace when the protective net 7 is damaged, or to easily remove the protective net 7 when cleaning, maintenance, or repair of the exhaust fan is required.

[0035] This mosquito-attracting exhaust fan, when in use, is installed inside the room's exhaust vent, with the mosquito-attracting lamp 3 facing inwards. The fan 2 is powered on and rotates, generating an outward airflow, providing basic functions such as removing polluted air, regulating humidity, lowering temperature, and improving air quality. The electric killing net 6 is powered on and in working condition. The mosquito-attracting lamp 3 actively attracts mosquitoes in the room. When mosquitoes fly towards the lamp 3, they are sucked into the exhaust pipe 1 by the suction generated by the fan 2. The airflow is accelerated by the tapering guide shroud 15 (along the exhaust direction), ensuring that the mosquitoes are reliably and accurately sprayed onto the electric killing net 6 for elimination. The overall structure is simple, adding active mosquito attraction and elimination functions to the basic functions of an exhaust fan without changing the overall size. It is easy to install and effectively achieves thorough mosquito elimination, ensuring food safety.
