[0002] The current traditional fan includes a shell, the rear end of the shell is the air inlet end, the front end is the air outlet end, an air supply component is installed in the middle of the rear end surface of the shell, a gas circulation cavity is provided inside the shell, the air supply component includes a motor installed on the rear end surface of the shell, and fan blades are installed on the motor shaft. The fan blades are driven to rotate by the motor to generate gas flow, thereby providing rapid air circulation to achieve the effect of heat dissipation.

[0003] However, in hot weather, mosquitoes will appear indoors, and when people rest or move around indoors, they will inevitably be bitten by mosquitoes, which will cause skin redness, pain, allergies and itching, and they may also spread diseases. Currently, the most common way to kill mosquitoes is to place mosquito traps to capture mosquitoes statically, that is, install ultraviolet lights or other mosquito-attracting lights indoors, and then set up electric grids around these lights. Although this method can kill mosquitoes, the bodies of mosquitoes will fall to the ground under the electric grid or on indoor facilities, and due to the indoor air circulation or people walking around, the bodies of mosquitoes will not be easy to concentrate, creating a new source of pollution indoors.

[0004] Therefore, the inventors have conducted research and development improvements based on the defects of the above two traditional facilities. Summary of the invention

[0031] The following is combined with Figures 1 to 5 This application is described in further detail.

[0032] The present application embodiment discloses a fan capable of catching flying insects, referring to Figure 1 , including a shell 1, the rear end of the shell 1 is an air inlet end 2, the front end is an air outlet end 3, a gas circulation cavity is arranged inside the shell 1, a mosquito attracting lamp (not shown in the figure) is arranged at the air inlet end 2 of the shell 1, generally, a motor is installed in the middle of the rear end surface of the shell 1, the mosquito attracting lamp can be designed into a ring structure, and can be installed at the peripheral position of the motor installation position, but the shape and installation method of the mosquito attracting lamp are not too restricted, and can be set according to the actual layout needs, but its main purpose is to attract mosquitoes to the air inlet end 2 side of the fan.

[0033] Reference Figures 2 to 4 In order to achieve the effect of centralized collection of mosquitoes and catching and killing mosquitoes, a mosquito dropping port 4 is arranged at the front side of the lower end of the side wall of the shell 1, and a vent 5 is arranged at the rear side. A mosquito collecting box 6 is installed at the lower end of the side wall of the shell 1, and a gas reflux chamber is arranged in the mosquito collecting box 6. The gas reflux chamber is provided with an air inlet 7 connected with the mosquito dropping port 4 on the front side of the upper end of the mosquito collecting box 6, and an air outlet 8 connected with the vent 5 is arranged on the rear side. After the mosquitoes fall into the mosquito collecting box 6, a certain intensity of negative pressure will be formed in the mosquito collecting box 6 during the continuous blowing of the fan, resulting in a relatively thin air content in the mosquito collecting box 6. In this way, the mosquitoes falling into the mosquito collecting box 6 will die quickly due to the long-term thin air, thereby achieving the effect of catching and killing mosquitoes.

[0034] In addition, in order to further prevent mosquitoes from being carried out or escaping from the air outlet 8 by the air flow in the gas reflux chamber, an isolation net 9 can be provided at the air outlet 8 of the mosquito collection box 6. In this embodiment, the isolation net 9 can be a filter net or a mesh filter plate, or an electric mosquito net, or a mesh sticker with glue for sticking mosquitoes and having mesh holes. At the same time, in order to increase the air intake and improve the effect of mosquitoes being sucked into the gas circulation chamber in the fan, a side wall of the shell 1 is provided along the circumference near the rear end surface. There are a plurality of air-increasing holes 10, wherein the vent 5 is connected to the air-increasing hole 10 located at the lower end of the side wall of the shell 1, or the air-increasing hole 10 located at the lower end of the side wall of the shell 1 is the vent 5; after the mosquitoes are sucked in from the air inlet end 2 of the fan, they will quickly hit the end surface of the air outlet end 3, and the fan is generally designed with an umbrella-shaped end surface of the air outlet end 3, that is, the cross-section of the end surface of the air outlet end 3 is an arc shape. Therefore, in order to further enhance the ability of the mosquitoes to fall to the mosquito drop mouth 4 faster after the impact, refer to Figure 5 A mosquito blocking net 11 can be arranged near the front end surface of the shell 1. 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 3, thereby achieving a better mosquito blocking effect.

[0035] In the present embodiment, in order to realize the effect of rapid disassembly and assembly of the mosquito collecting box 6 and facilitate cleaning, a mounting position of the mosquito collecting box 6 is arranged at the lower end of the side wall of the shell 1, and a positioning enclosure 12 is arranged at the lower end of the side wall of the shell 1 surrounding the mounting position, and all the positioning enclosures 12 surround a mounting groove 13 of a frame-type structure, the air inlet 7 is arranged at the front side of the bottom of the mounting groove 13, and the air outlet 8 is arranged at the rear side of the bottom of the mounting groove 13; the upper end of the mosquito collecting box 6 is adapted to be installed in the mounting groove 13, and in order to facilitate rapid installation and disassembly, a first magnetic suction groove 14 can be arranged in the middle of the bottom of the mounting groove 13, and a first magnetic suction member (not shown in the figure) can be installed in the first magnetic suction groove 14, and a second magnetic suction member (not shown in the figure) cooperating with the first magnetic suction member is arranged in the middle of the upper end surface of the mosquito collecting box 6. The magnetic suction members in the present embodiment can be magnets that attract each other, or one of them is a magnet and the other is an iron sheet or a steel sheet.

[0036] In the present embodiment, in order to facilitate the cleaning of mosquito corpses in the mosquito collection box 6, the mosquito collection box 6 can be designed as an assembly, that is, the mosquito collection box 6 includes a box body 15 with an opening at the upper end and a baffle 16, the gas reflux chamber is in the box body 15, the baffle 16 is installed at the rear side of the opening of the box body 15, and the front edge of the baffle 16 and the left and right edges and the front edge of the opening of the box body 15 form an air inlet 7; and a second magnetic suction groove 17 can be provided on the front side of the upper end face of the baffle 16, and the second magnetic suction member is installed in the second magnetic suction groove 17, and the air outlet 8 is provided at the rear side of the baffle 16.

[0037] In order to facilitate the rapid guidance of mosquitoes to the mosquito collection area of ​​the mosquito collection box 6, the front side wall of the box body 15 is inclined toward the rear side and is provided with a guide slope 18. In order to prevent mosquitoes from escaping from the air inlet 7, a mosquito barrier 19 can be provided in the gas reflux chamber between the air inlet 7 and the air outlet 8. In this embodiment, the mosquito barrier 19 is a plate-like structure, and its left and right edges are respectively provided with rotating shafts. The mosquito barrier 19 can be hingedly installed between the left and right side walls of the box body 15, and the rotating shaft is rotatably installed on the side wall of the box body 15 on the corresponding side. In this embodiment, the left and right side edges of the mosquito barrier 19 are respectively close to the side wall of the corresponding side of the box body 15, so that A small gap is generated between the side of the mosquito barrier 19 and the corresponding side wall of the box body 15, which does not hinder the swing of the mosquito barrier 19 on the one hand, and can achieve the effect of preventing mosquitoes from escaping on the other hand. At the same time, the lower edge of the mosquito barrier 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 this embodiment, the inner cavity of the box body 15 behind the mosquito barrier 19 can be understood as a mosquito collection place; in addition, the mosquito barrier 19 can also be designed to have an electric mosquito net, or a mesh sticker with glue for sticking mosquitoes and mesh holes. After such a design, the mosquitoes can be directly caught and killed after falling.

[0038] The embodiment of the present application discloses a fan capable of catching flying insects. When the fan is started, a mosquito attractant lamp will attract mosquitoes to the side of the air inlet end 2 of the fan. Due to the negative pressure formed by the operation of the fan, the mosquitoes will be sucked into the gas circulation cavity in the fan, and the mosquitoes will be quickly hit onto the mosquito blocking net 11, and then fall to the mosquito landing mouth 4. Due to the negative pressure generated by the gas flow in the gas reflux cavity, the mosquitoes will be sucked into the mosquito collecting box 6. When negative pressure is generated in the gas reflux cavity, the mosquito barrier 19 will swing backward to an open state, and the mosquitoes will be brought into the mosquito collection area through the gap between the lower edge of the mosquito barrier 19 and the inner bottom surface of the box body 15, thereby achieving the effect of concentrated mosquito catching and killing.

[0039] It should be noted that the front, rear, left, right, top, and bottom directions described in this embodiment are all described based on normal directions of the fan when it is installed and used.

[0040] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
