Description

[Technical Field]

[0001] This application relates to the field of fans, and in particular to fans for capturing flying insects. [Background technology]

[0002] A conventional fan includes a housing, the rear end of which is an intake end and the front end of which is an exhaust end. A blower assembly is attached to the center of the rear end surface of the housing, and a gas flow chamber is provided inside the housing. The blower assembly includes a motor attached to the rear end surface 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, and when people are resting or doing activities indoors, they are inevitably bitten by mosquitoes, causing swelling, pain, allergies, and itching on the skin, and there is a risk of contracting diseases as a result. Currently, the most common way to control mosquitoes is to statically capture mosquitoes by installing mosquito traps, that is, installing ultraviolet lamps or other lamps that can attract mosquitoes indoors, and then installing an electrical grid around these lamps. Although this method can achieve mosquito control, mosquito corpses may fall onto the ground below the electrical grid or onto indoor facilities, and when indoor air circulates or people walk, the mosquito corpses are difficult to concentrate, becoming a new source of indoor pollution.

[0004] Therefore, the inventors have conducted research and development and made improvements based on the shortcomings of the above two types of conventional facilities. Summary of the Invention [Problem to be solved by the invention]

[0005] The fan not only provides the effect of dissipating heat and lowering the temperature, but also has the function of exterminating mosquitoes, and can collect the corpses of the exterminated mosquitoes in a concentrated manner, thereby improving the hygienic and environmentally friendly effects.

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

[0018] 1. The structure of the fan is improved by providing a mosquito attractant 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. This attracts mosquitoes to the intake end of the fan through the mosquito attractant. The negative pressure created by the gas flowing through the gas flow chamber from the intake end to the exhaust end of the fan causes the mosquitoes to be sucked into the gas flow chamber and quickly collide with the end face of the exhaust end. They then fall to the lower end of the inner wall of the housing and enter the gas return chamber through the intake port, where they are collected in a concentrated manner. This not only provides the fan with the effect of dissipating heat and reducing temperature, but also provides the function of eliminating mosquitoes, and can also collect the mosquito carcasses in a concentrated manner after the mosquitoes have been exterminated, thereby improving hygiene and environmental friendliness.

[0019] 2. The mounting groove formed in the positioning enclosure allows for quick positioning of the mosquito collecting box, and the mutual engagement and suction of the two magnetic suction members makes the removal and installation of the mosquito collecting box easier and faster.

[0020] 3. The guide slope design allows the gas to be guided quickly, and the mosquitoes that fall down due to the passing gas can be quickly brought to the mosquito collection point of the mosquito collection box.

[0021] 4. The design of the mosquito blocking element can prevent and reduce the possibility of mosquitoes entering the mosquito collecting area escaping through the air intake.

[0022] 5. The design of the mosquito net allows mosquitoes to be sucked into the gas flow chamber and quickly collide with the mosquito net, effectively reducing the situation where mosquitoes are blown out from the exhaust end of the housing, and better improving the accuracy of mosquitoes falling into the mosquito trap opening.

[0023] 6. The ventilation holes design can increase the amount of air intake and improve the effectiveness of mosquito inhalation.

[0024] 7. The design of the separating net can reduce the situation where mosquitoes are blown out or escape from the exhaust vent, improving the effect of mosquito extermination. [Brief explanation of the drawings]

[Figure 5] FIG. 5 is a partially enlarged structural view of a portion A in FIG. 4. DETAILED DESCRIPTION OF THE INVENTION

[0026] The present invention will be described in more detail below with reference to FIGS.

[0027] The embodiment of the present application discloses a fan for capturing flying insects, and refer to FIG. 1. The fan includes a housing 1, the rear end of which is an intake end 2, and the front end of which is an exhaust end 3. A gas flow chamber is provided inside the housing 1, and a mosquito light (not shown) is provided at the intake end 2 of the housing 1. Generally, a motor is attached to the center of the rear end face of the housing 1, and the mosquito light is designed to have a ring-shaped structure and is attached to the outer periphery of the motor attachment position. There are no restrictions on the shape and installation form of the mosquito light, and it can be configured according to the needs of the actual layout as long as it achieves the main purpose of attracting mosquitoes so that they reach the intake end 2 of the fan.

[0028] 2 to 4, in order to achieve the effects of intensive collection and extermination of mosquitoes, a mosquito trap opening 4 is provided at the front of the lower end of the side wall of the housing 1 and a ventilation opening 5 is provided at the rear. A mosquito collecting box 6 is attached to the lower end of the side wall of the housing 1. A gas return chamber is provided within the mosquito collecting box 6. The gas return chamber has an air intake opening 7 at the front of the upper surface of the mosquito collecting box 6, which communicates with the mosquito trap opening 4, and an air exhaust opening 8 at the rear, which communicates with the ventilation opening 5. After mosquitoes fall into the mosquito collecting box 6, a certain amount of negative pressure is created within the mosquito collecting box 6 during the process of continuous air blowing by the fan, causing the air content in the mosquito collecting box 6 to become sparse. In this way, the mosquitoes that fall into the mosquito collecting box 6 will quickly die due to the sparse air for a long time, thereby achieving the effect of mosquito extermination.

[0029] In order to further prevent mosquitoes from being carried away or escaping through the exhaust port 8 by the air current passing through the gas return chamber, a separating net 9 may be provided at the exhaust port 8 of the mosquito collecting box 6. In this embodiment, the separating net 9 may be a strainer or filter mesh, or may be an electric grid for repelling mosquitoes, or a mesh patch with adhesive for sticking mosquitoes. In addition, in order to increase the air volume and improve the effect of mosquitoes being sucked into the gas circulation chamber in the fan, a plurality of air increase holes 10 are provided around the side wall of the housing 1 near the rear end surface. Here, the ventilation holes 5 communicate with the air increase holes 10 located at the lower end of the side wall of the housing 1, and the housing The airflow holes 10 located at the lower end of the side wall of the housing 1 may be air vents 5, so that mosquitoes can quickly collide with the end face of the outlet end 3 after being sucked in through the intake end 2 of the fan. Generally, when designing a fan, the end face of the outlet end 3 is designed to be umbrella-shaped, that is, the cross section of the end face of the outlet end 3 is shaped like an arc, so that mosquitoes can quickly fall to the mosquito outlet 4 after impact. To further improve this, see FIG. 5 , a mosquito screen 11 may be provided near the front end face 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 of the outlet end 3 and improve the mosquito prevention effect.

[0030] In this embodiment, to achieve the effects of quick installation and removal of the mosquito collecting box 6 and easy cleaning, an installation position for the mosquito collecting box 6 is provided at the lower end of the side wall of the housing 1, and a positioning enclosure 12 is provided at the lower end of the side wall of the housing 1 surrounding the periphery of the installation position. All of the positioning enclosures 12 surround a frame-shaped installation groove 13, with an air intake 7 provided at the front side of the bottom of the installation groove 13 and an air exhaust 8 provided at the rear side of the bottom of the installation groove 13. The upper end of the mosquito collecting box 6 is fitted into the installation groove 13. To enable quick installation and removal, a first magnetic attraction groove 14 may be provided at the center of the bottom of the installation groove 13, and a first magnetic attraction member (not shown) may be provided in the first magnetic attraction groove 14. A second magnetic attraction member (not shown) engaging with the first magnetic attraction member is provided at the center of the upper surface of the mosquito collecting box 6. The magnetic attraction members in this embodiment may be magnets that attract each other, or one may be a magnet and the other an iron or steel piece.

[0031] In this embodiment, in order to facilitate cleaning of the mosquito corpses in the mosquito collecting box 6, the mosquito collecting box 6 may be designed as an assembly, i.e., the mosquito collecting box 6 includes a box body 15 with an opening at the top end and a partition plate 16, the gas return chamber is located in the box body 15, the partition plate 16 is attached to the rear position of the opening of the box body 15, the front edge of the partition plate 16 and the left and right edges and front edge of the opening of the box body 15 form an air intake port 7, a second magnetic attraction groove 17 may be provided at the front position of the upper end surface of the partition plate 16, a second magnetic attraction member is attached in the second magnetic attraction groove 17, and an air exhaust port 8 is provided at the rear position of the partition plate 16.

[0032] In order to facilitate the mosquitoes to be quickly guided to the mosquito collecting point of the mosquito collecting box 6, a guide slope 18 is provided on the front wall of the box body 15, inclined toward the rear side. In order to prevent the mosquitoes from escaping through the air inlet 7, a mosquito blocking member 19 may be provided in the gas return chamber between the air inlet 7 and the air outlet 8. In this embodiment, the mosquito blocking member 19 has a plate-like structure, and a rotation shaft is provided on each of its left and right edges. The mosquito blocking member 19 may be hingedly attached between the left and right side walls of the box body 15, and the rotation shaft is rotatably attached to the corresponding side wall of the box body 15. In this embodiment, the left and right sides of the mosquito blocking member 19 are respectively adjacent to the corresponding side walls of the box body 15. As a result, a relatively small gap is created between the side edge of the mosquito blocking element 19 and the corresponding side wall of the box body 15, which does not hinder the swinging of the mosquito blocking element 19 while preventing mosquitoes from escaping. The lower edge of the mosquito blocking element 19 is close to or abuts 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 element 19 can be understood as the mosquito collecting area. The mosquito blocking element 19 can also be designed as a mesh patch structure with an electric grid for repelling mosquitoes or with an adhesive for sticking mosquitoes. With this design, the effect of eliminating flying insects can be directly achieved after the mosquitoes have fallen.

[0033] In the fan for capturing flying insects disclosed in the embodiments of the present application, when the fan is operating, the mosquito attracting light attracts mosquitoes toward the intake end 2 of the fan, and the negative pressure created by the operation of the fan causes the mosquitoes to be sucked into the gas circulation chamber inside the fan, where they quickly collide with the mosquito net 11 and then fall into the mosquito trap opening 4. The negative pressure caused by the gas flow in the gas circulation chamber can suck the mosquitoes into the mosquito collecting box 6, so when negative pressure is generated in the gas circulation chamber, the mosquito blocking member 19 swings backward and opens, and the mosquitoes are brought into the mosquito collecting 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] In addition, the directions such as front, rear, left, right, up, and down described in this embodiment are all explained in terms of the normal directions when the fan is installed or in use.

[0035] The above are all preferred embodiments of the present application, and the scope of protection of the present application is not limited thereby. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
