DETAILED DESCRIPTION

[0031] The application will be further described in detail below in combination with Figs. 1 to 5.

[0032] The embodiment of the application discloses a fan capable of capturing flying insects. Referring to Fig. 1, the fan comprises a housing 1, the rear end of the housing 1 is an air inlet end 2, the front end is an air outlet end 3, the housing 1 is internally provided with a gas flow cavity, the air inlet end 2 of the housing 1 is provided with a mosquito lamp (not shown in the figure), generally, a motor is installed at the middle of the rear end surface of the housing 1, the mosquito lamp can be designed as a ring-shaped structure and is installed at the peripheral position of the motor installation position, but the shape and installation mode of the mosquito lamp are not limited too much, and can be set according to the actual layout needs, as long as the main purpose of attracting mosquitoes to the air inlet end 2 side of the fan can be achieved.

[0033] Referring to Figs. 2 to 4, in order to realize the effect of concentrated collection and capture of mosquitoes, the front side position of the lower end of the side wall of the housing 1 is provided with a mosquito falling port 4, the rear side position is provided with a ventilation port 5, the lower end of the side wall of the housing 1 is installed with a mosquito collection box 6, the mosquito collection box 6 is internally provided with a gas backflow cavity, the gas backflow cavity is provided with an air inlet 7 communicated with the mosquito falling port 4 at the front side of the upper end surface of the mosquito collection box 6, and is provided with an air outlet 8 communicated with the ventilation port 5 at the rear side, after the mosquitoes fall into the mosquito collection box 6, due to the formation of a certain intensity of negative pressure in the mosquito collection box 6 in the process of continuous blowing of the fan, the air content of the mosquito collection box 6 is relatively thin, so that the mosquitoes falling into the mosquito collection box 6 will die quickly due to long-time air thinning, and the effect of capturing mosquitoes is achieved.

[0034] In addition, in order to further prevent mosquitoes from being taken out or escaping from the air outlet 8 by the airflow in the gas reflux cavity, a separation net 9 can be arranged at the air outlet 8 of the mosquito collecting box 6. In the embodiment, the separation net 9 can be a filter screen or a grid-shaped filter plate, or an electric mosquito net, or a meshed adhesive paste for sticking mosquitoes. In order to increase the air inflow and improve the effect of mosquitoes being sucked into the gas flow cavity of the fan, a plurality of air inlet holes 10 are arranged on the side wall of the shell 1 near the rear end face along the circumference. The air inlet hole 10 at the lower end of the side wall of the shell 1 is communicated with the air inlet 5, or the air inlet hole 10 at the lower end of the side wall of the shell 1 is the air inlet 5. After the mosquitoes are sucked into the fan from the air inlet end 2, they will quickly impact on the end face of the air outlet end 3. Generally, in the design of the fan, the end face of the air outlet end 3 is designed as an umbrella shape, that is, the cross section of the end face of the air outlet end 3 is arc-shaped. Therefore, in order to further improve the falling speed of the mosquitoes after impact to the position of the mosquito falling port 4, referring to FIG. 5, a mosquito blocking net 11 can be arranged in the shell 1 near the front end face. The mesh of the mosquito blocking net 11 is generally relatively dense, which can reduce the phenomenon of mosquitoes being blown out of the air outlet end 3, so that the blocking effect of mosquitoes is better.

[0035] In the embodiment, in order to realize the quick disassembly and assembly of the mosquito collecting box 6 and facilitate cleaning, the lower end of the side wall of the shell 1 is provided with a mounting position of the mosquito collecting box 6. The lower end of the side wall of the shell 1 is provided with a positioning fence 12 surrounding the mounting position. All the positioning fences 12 surround the mounting groove 13 in a frame structure. The air inlet 7 is arranged on the front side of the groove bottom of the mounting groove 13, and the air outlet 8 is arranged on the rear side of the groove bottom of the mounting groove 13. The upper end of the mosquito collecting box 6 is adapted to be mounted in the mounting groove 13. In order to realize quick mounting and dismounting, a first magnetic attraction groove 14 is arranged in the middle of the groove bottom of the mounting groove 13. A first magnetic attraction piece (not shown in the figure) is mounted in the first magnetic attraction groove 14. The middle of the upper end face of the mosquito collecting box 6 is provided with a second magnetic attraction piece (not shown in the figure) matched with the first magnetic attraction piece. In the embodiment, the magnetic attraction pieces can be magnets that attract each other, or one of them can be a magnet and the other can be an iron sheet or a steel sheet.

[0036] In the embodiment, in order to facilitate cleaning of the mosquitoes in the mosquito collecting box 6, the mosquito collecting box 6 can be designed as an assembly, that is, the mosquito collecting box 6 includes a box body 15 with an opening at the upper end and a partition plate 16. The gas reflux cavity is in the box body 15. The partition plate 16 is mounted at the rear side of the opening of the box body 15. The front edge of the partition plate 16 and the left and right edges and the front edge of the opening of the box body 15 form the air inlet 7. The front side of the upper end face of the partition plate 16 can be provided with a second magnetic attraction groove 17. A second magnetic attraction piece is mounted in the second magnetic attraction groove 17. The air outlet 8 is arranged at the rear side of the partition plate 16.

[0037] In order to facilitate the mosquito to be quickly guided to the mosquito collecting place of the mosquito collecting box 6, the front side wall of the box body 15 is inclined to be provided with a guide slope 18 in the rear direction, and in order to prevent the mosquito from escaping from the air inlet 7, a mosquito blocking piece 19 can be arranged in the gas backflow cavity between the air inlet 7 and the air outlet 8. In the embodiment, the mosquito blocking piece 19 is a plate-shaped structure, the left and right edges of which are respectively provided with rotating shafts, and the mosquito blocking piece 19 is hingedly installed between the left and right side walls of the box body 15. The rotating shafts are rotatably installed on the corresponding side walls of the box body 15. In the embodiment, the left and right side edges of the mosquito blocking piece 19 are respectively close to the side walls of the corresponding side of the box body 15, so that a small gap is formed between the side edge of the mosquito blocking piece 19 and the corresponding side wall of the box body 15. On the one hand, the swinging of the mosquito blocking piece 19 is not hindered, and on the other hand, the effect of preventing the mosquito from escaping is achieved. At the same time, the lower edge of the mosquito blocking piece 19 is close to or abuts against the lower side of the guide slope 18 or the inner bottom surface of the box body 15. In the embodiment, the rear inner cavity of the box body 15 can be understood as the mosquito collecting place. In addition, the mosquito blocking piece 19 can also be designed to have an electric mosquito net, or to have a structure of a glue, a mesh sticker with mesh holes for sticking mosquitoes. After the design, the mosquitoes can be directly captured and killed after falling.

[0038] The fan disclosed in the embodiment of the application can capture flying insects. When the fan is started to work, the mosquito lamp attracts mosquitoes to one side of the air inlet end 2 of the fan. Due to the negative pressure formed by the working fan, the mosquitoes are sucked into the gas flow cavity in the fan. The mosquitoes are quickly impacted on the mosquito blocking net 11 and then fall to the mosquito falling port 4. Due to the negative pressure generated by the gas flow in the gas backflow cavity, the mosquitoes are sucked into the mosquito collecting box 6. When the negative pressure is generated in the gas backflow cavity, the mosquito blocking piece 19 swings backward to an open state. The mosquitoes are brought into the mosquito collecting place from the gap between the lower edge of the mosquito blocking piece 19 and the inner bottom surface of the box body 15, so as to achieve the effect of concentrated capture and killing of mosquitoes.

[0039] It should be noted that the front, rear, left, right, upper, lower and other directions described in the embodiment are described in the normal direction of the fan during installation and use.

[0040] The above are the preferred embodiments of the application, which do not limit the protection scope of the application. Therefore, any equivalent changes made on the structure, shape and principle of the application should be covered within the protection scope of the application.
