Description

Technical Field

[0001] This application relates to the field of fans, and particularly to fans for catching flying insects.

Background Art

[0002] Conventional fans include a housing. The rear end of the housing is the intake end, and the front end is the exhaust end. An air blowing assembly is attached to the central part of the rear end face inside the housing, and a gas flow chamber is provided inside the housing. The air blowing assembly includes a motor attached to the rear end face of the housing, and blades are attached to the axis of the motor. The operation of the motor rotates the blades to flow gas, and further provides the effect of quickly circulating air to achieve heat dissipation.

[0003] In hot weather, mosquitoes appear indoors. When people rest and move indoors, they cannot avoid being stung by mosquitoes, resulting in skin swelling, pain, allergies, and itching, and there is a possibility of contracting diseases therefrom. Currently, for mosquito control, there is a form of statically capturing mosquitoes by arranging mosquito capture devices, that is, installing an ultraviolet lamp or a mosquito attracting lamp, which is another lamp that may attract mosquitoes, indoors, and then installing an electric grid around these lamps. Such a form can achieve mosquito control, but the dead bodies of mosquitoes may fall on the ground below the electric grid or on indoor facilities. Also, when the indoor air circulates or people walk, the dead bodies of mosquitoes are not likely to concentrate, becoming a new source of pollution for the indoor environment.

[0004] Therefore, the inventors have conducted research and development and improvement based on the drawbacks existing in the above two types of conventional facilities.

[0014] In some embodiments, a mosquito net is provided near the front end surface inside the housing.

[0015] In some embodiments, multiple ventilation holes are provided around the side wall of the housing near the rear end surface, the ventilation opening communicates with the ventilation holes located at the lower end of the side wall of the housing, and a mosquito-attracting lamp is provided at the intake end of the housing.

[0016] In some embodiments, the mosquito collection box is provided with a separation net at the exhaust port. [Effects of the Invention]

[0017] In summary, this application includes at least one of the following beneficial technical effects.

[0018] 1. By improving the fan structure and installing a mosquito-attracting lamp at the intake end of the fan housing, and attaching a mosquito collection box to the lower end of the side wall of the housing, mosquitoes are attracted to the intake end of the fan by the mosquito-attracting lamp, and the negative pressure created in the gas flowing through the gas circulation chamber from the intake end to the exhaust end of the fan causes the mosquitoes to be drawn into the gas circulation chamber, quickly collide with the end face of the exhaust end, and then fall to the lower end of the inner wall of the housing, where they enter the gas recirculation chamber through the intake port and are collected intensively. As a result, the fan not only provides a heat dissipation and cooling effect, but also has a function to exterminate mosquitoes, and the dead mosquitoes can be collected intensively after extermination, improving hygiene and environmental friendliness.

[0019] 2. The mounting grooves formed in the positioning enclosure enable rapid positioning of the mosquito collection box, and the mutual engagement attraction of the two magnetic attraction members makes it easier and faster to remove and install the mosquito collection box.

[0020] 3. The design of the guide slope allows for the rapid flow of gas, and also allows mosquitoes that have fallen due to the passing gas to be quickly carried to the mosquito collection area of ​​the mosquito collection box.

[0021] 4. The design of the mosquito-blocking component prevents and reduces the possibility of mosquitoes that have entered the mosquito collection area escaping through the air intake.

[0022] 5. The design of the mosquito net effectively reduces the situation in which mosquitoes are drawn into the gas circulation chamber and quickly collide with the mosquito net, causing them to be blown out from the exhaust end of the housing, and also improves the accuracy of mosquitoes falling into the mosquito drop-off opening.

[0023] 6. The design of the increased air vents can increase the amount of air intake while also improving the effectiveness of mosquito trapping.

[0024] 7. The design of the separation net reduces the chances of mosquitoes being blown out or escaping from the exhaust vent, thereby improving the effectiveness of mosquito control. [Brief explanation of the drawing]

[Figure 5] It is a partial enlarged structure diagram of the location A in FIG. 4.

Mode for Carrying Out the Invention

[0026] Hereinafter, the present application will be described in more detail with reference to FIGS. 1 to 5.

[0027] The embodiment of the present application discloses a fan for catching flying insects. Referring to FIG. 1, it includes a housing 1. The rear end portion of the housing 1 is an intake end 2, and the front end portion is an exhaust end 3. A gas flow chamber is provided inside the housing 1. A mosquito attracting lamp (not shown) is provided at the intake end 2 of the housing 1 Generally, a motor is attached to the central portion of the rear end face of the housing 1. The mosquito attracting lamp is designed to have an annular structure. If it is attached to the outer peripheral position of the motor attachment position, the shape and attachment form of the mosquito attracting lamp are not limited. As long as the main purpose of attracting mosquitoes to reach the intake end 2 side of the fan can be achieved, it can be set according to the actual layout requirements.

[0028] Referring to Figures 2 to 4, in order to achieve concentrated collection and extermination of mosquitoes, the lower end of the side wall of the housing 1 is provided with a mosquito exit opening 4 at the front and a ventilation opening 5 at the rear. A mosquito collection box 6 is attached to the lower end of the side wall of the housing 1. A gas recirculation chamber is provided inside the mosquito collection box 6. The gas recirculation chamber has an intake port 7 on the front side of the upper end surface of the mosquito collection box 6 that communicates with the mosquito exit opening 4, and an exhaust port 8 on the rear side that communicates with the ventilation opening 5. After mosquitoes fall into the mosquito collection box 6, a constant negative pressure is formed inside the mosquito collection box 6 as the fan continuously blows air. As a result, the air content inside the mosquito collection box 6 is dilute, and in this way, mosquitoes that fall into the mosquito collection box 6 die rapidly due to the dilute air for a long period of time, thus achieving the effect of exterminating mosquitoes.

[0029] Furthermore, in order to further prevent mosquitoes from being carried out or escaping through the exhaust port 8 by the airflow that has passed through the gas circulation chamber, a separation net 9 may be provided at the exhaust port 8 of the mosquito collection box 6. In this embodiment, the separation net 9 may be a strainer or filter mesh, or an electric grid for mosquito repellent, or a mesh patch with an adhesive for trapping mosquitoes. In addition, in order to increase the airflow and improve the effect of drawing mosquitoes into the gas circulation chamber in the fan, a plurality of air-increasing holes 10 are provided around the side wall of the housing 1 near the rear end surface, where the ventilation opening 5 communicates with the air-increasing holes 10 located at the lower end of the side wall of the housing 1. The air inlet 10 located at the lower end of the side wall of the housing 1 may also be an air vent 5. After a mosquito is drawn in from the intake end 2 of the fan, it quickly collides with the end face of the exhaust end 3. Generally, when designing the fan, the end face of the exhaust end 3 is designed to be umbrella-shaped, that is, the cross-section of the end face of the exhaust end 3 is arc-shaped. Therefore, to further improve this, the mosquito can fall more quickly to the mosquito drop-off opening 4 after impact. Referring to Figure 5, a mosquito screen 11 may be provided near the front end of the housing 1. Generally, the mesh of the mosquito screen 11 is relatively dense, which can reduce the phenomenon of mosquitoes being blown out from the exhaust end 3 and improve the mosquito-stopping effect.

[0030] In this embodiment, in order to achieve the effect that the mosquito collection box 6 can be quickly attached and detached and is easy to clean, a mounting position for the mosquito collection box 6 is provided at the lower end of the side wall of the housing 1, a positioning enclosure 12 is provided at the lower end of the side wall of the housing 1 surrounding the mounting position, all positioning enclosures 12 surround a frame-shaped mounting groove 13, an air intake 7 is provided on the front side of the bottom of the mounting groove 13, an exhaust vent 8 is provided on the rear side of the bottom of the mounting groove 13, the upper end of the mosquito collection box 6 is fitted into the mounting groove 13 and mounted, and in order to enable quick attachment and detachment, a first magnetic attraction groove 14 may be provided in the center of the bottom of the mounting groove 13, a first magnetic attraction member (not shown) is mounted in the first magnetic attraction groove 14, and a second magnetic attraction member (not shown) that engages with the first magnetic attraction member is provided in the center of the upper end surface of the mosquito collection box 6, and the magnetic attraction members in this embodiment may be magnets that attract each other, or one is a magnet and the other is an iron piece or steel piece.

[0031] In this embodiment, in order to facilitate the cleaning of dead mosquitoes inside the mosquito collection box 6, the mosquito collection box 6 may be designed as an assembly, that is, the mosquito collection box 6 includes a box body 15 having an opening at its upper end and a partition plate 16, the gas recirculation chamber is located inside the box body 15, the partition plate 16 is attached to the rear side of the opening of the box body 15, the front edge of the partition plate 16 and the left, right, and front edges of the opening of the box body 15 form an air intake 7, a second magnetic attraction groove 17 may be provided at the front side of the upper end surface of the partition plate 16, a second magnetic attraction member is attached inside the second magnetic attraction groove 17, and an exhaust port 8 is provided at the rear side of the partition plate 16.

[0032] To facilitate the rapid guidance of mosquitoes to the mosquito collection area of ​​the mosquito collection box 6, a guide slope 18 is provided on the front wall of the box body 15, inclined toward the rear. To prevent mosquitoes from escaping through the air intake 7, a mosquito blocking member 19 may be provided in the gas recirculation chamber between the air intake 7 and the exhaust 8. In this embodiment, the mosquito blocking member 19 has a plate-like structure, with pivot axes provided on its left and right edges. The mosquito blocking member 19 may be attached to the left and right side walls of the box body 15 by hinge connection, with the pivot axes rotatably attached to the corresponding side wall of the box body 15. In this embodiment, both the left and right sides of the mosquito blocking member 19 are close to the corresponding side wall of the box body 15. As a result, a relatively small gap is created between the side of the mosquito-blocking member 19 and the corresponding side wall of the box body 15, which does not hinder the swinging of the mosquito-blocking member 19 while preventing mosquitoes from escaping. Furthermore, the lower edge of the mosquito-blocking member 19 is close to or in contact with the lower position of the guide slope 18 or the inner bottom surface of the box body 15. In this embodiment, the inner chamber of the box body 15 behind the mosquito-blocking member 19 can be understood as a mosquito collection area. In addition, the mosquito-blocking member 19 may be designed with an electric grid for mosquito repellent or with an adhesive for trapping mosquitoes, and may be designed as a mesh patch with a mesh. Designing it in this way directly achieves the effect of eliminating flying insects after mosquitoes have fallen.

[0033] In the embodiment of the present invention, when the fan is operating, the mosquito-attracting lamp draws mosquitoes to the intake end 2 of the fan. The negative pressure created by the operation of the fan draws the mosquitoes into the gas circulation chamber inside the fan, where they quickly collide with the mosquito-stopping net 11 and then fall into the mosquito drop-off opening 4. The negative pressure created by the gas flow in the gas circulation chamber draws the mosquitoes into the mosquito collection box 6. When negative pressure is generated in the gas circulation chamber, the mosquito-blocking member 19 swings backward and opens, allowing mosquitoes to be brought into the mosquito collection area through the gap between the lower edge of the mosquito-blocking member 19 and the inner bottom surface of the box body 15, thereby achieving the effect of concentrated mosquito extermination.

[0034] Note that the directions such as front, back, left, right, up, and down described in this embodiment are all explained in terms of the normal orientation when the fan is installed or in use.

[0035] All of the above are preferred embodiments of the present application, and the scope of protection of the present application is not limited thereto. Therefore, equivalent modifications based on the structure, shape, and principle of the present application should all be included within the scope of protection of the present application.
