Description

Technical Field

[0001] The utility model relates to the technical field of agricultural production, in particular to a mosquito and fly catching window screen. Background Art

[0002] During the process of livestock breeding, the respiration, excretion of animals in the breeding house and cleaning water, etc. increase the humidity in the breeding house. Mosquitoes and flies like humid environments, so a large number of mosquitoes and flies will be attracted inside the breeding house.

[0003] Mosquitoes and flies can spread a variety of diseases, and biting animals will cause itching and discomfort to the animals. Seriously, it may affect the health of the animals. Similarly, a large number of mosquitoes and flies flying in the breeding house will not only produce noise to interfere with the animals, but also pollute the air, affecting the working environment and physical health of the breeding personnel.

[0004] In traditional agricultural livestock breeding, most windows use screen meshes to block mosquitoes. The blockage of the screen mesh on the window cannot fundamentally eliminate mosquitoes. Mosquitoes can still enter the livestock living area through positions such as human and livestock passages and sewage outlets, affecting the livestock. Conventional drug mosquito control will damage the environment and may also affect the livestock.

[0005] In the Chinese utility model patent with the patent application number 202020741426.3, a small insect mosquito control device for livestock breeding is proposed. This device mainly has the following problems: First, the device needs to be placed inside the breeding house for use, so mosquitoes and flies will still enter the breeding house, affecting the environment and animals inside the breeding house, and not fundamentally solving the problem of mosquitoes and flies affecting the environment and animal health inside the breeding house; Second, only relying on lights and electric grids to lure and kill mosquitoes and flies will consume a large amount of electric energy after long-term use, increasing the breeding cost of the breeding factory. Content of the Utility Model

[0006] The main technical problem to be solved by the utility model is to provide a mosquito and fly catching window screen, which uses the livestock itself as the most effective trapping source, and uses the mosquito catching window screen installed on the window of the breeding house to effectively kill mosquitoes and flies, achieving the purpose of ecological environmental protection on the basis of effectively reducing the density of mosquitoes and flies around the breeding house, and solving the problem that mosquitoes and flies enter the breeding house and affect the internal environment and animal health.

[0007] To solve the above technical problems, the utility model provides the following technical solutions:

[0008] A mosquito and fly catching window screen includes a frame. An inner net and an outer net arranged side by side are installed on the frame. A net cavity is formed between the inner net and the outer net. The outer net includes several net blocks arranged sequentially from top to bottom. A horizontal gap is formed between every two adjacent net blocks;

[0009] The frame includes a framework. Grooves are arranged around the framework on both side surfaces of the framework. The grooves are square-shaped. The edges of the inner net and the outer net are both pressed tightly into the grooves by pressing cotton. A cleaning port is arranged on the lower side of the inner peripheral surface of the framework. The cleaning port communicates the inside of the net cavity with the outer side surface of the framework.

[0010] The following is the further optimization of the above technical solution by the present utility model:

[0011] Flanges are arranged on one side edge of the net blocks located in the transverse gaps. The flanges are all arranged in the net cavity. A transverse gap is formed between every two adjacent flanges.

[0012] Further optimization: The transverse gaps are all in the shape of a trumpet-shaped tapered opening that is wider outside and narrower inside.

[0013] Further optimization: Support lines are arranged at the bending parts of the flanges. The support lines extend horizontally. The support lines are connected to the corresponding net blocks. Both ends of the support lines are pressed tightly in the corresponding grooves by pressing cotton.

[0014] Further optimization: A cover is installed at the outlet end of the cleaning port.

[0015] The present utility model adopts the above technical solution and has the following beneficial effects:

[0016] 1. The present utility model is ingeniously conceived and reasonable in structure. It can block mosquitoes and flies from entering the breeding shed, use the smell emitted by livestock in the breeding shed to the outside as a trapping source, and trap and kill mosquitoes and flies inside the net cavity, thus realizing the effective killing of mosquitoes and flies and solving the problem that mosquitoes and flies enter the inside of the breeding shed and affect the internal environment and animal health.

[0017] 2. During the whole process of killing mosquitoes and flies by the screen window, there is no harm to the environment, so the purpose of ecological environmental protection is achieved on the basis of ensuring the effective killing of mosquitoes and flies.

[0018] 3. The present utility model adopts a double-layer blocking and killing structure, breaking through the defect that the traditional screen window only has a single effect of blocking mosquitoes and flies and cannot effectively kill mosquitoes and flies, and fundamentally reducing the density of mosquitoes and flies around the breeding shed.

[0019] 4. The present utility model does not use energy such as light and electricity, nor does it use chemical agents. Moreover, it has a simple structure, low cost, and can be reused, thus effectively reducing the breeding cost input of farmers.

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0029] As Figures 1-5 collectively shown, a mosquito and fly catching screen window includes a frame 1. An inner net 2 and an outer net 3 arranged side by side are installed on the frame 1. A net cavity 4 is formed between the inner net 2 and the outer net 3. The outer net 3 includes a plurality of net blocks 31 arranged successively from top to bottom. A horizontal gap 32 is formed between every two adjacent net blocks 31.

[0030] In this embodiment, the frame 1 is the basic framework of the entire screen window, used to support and fix all components of the screen window.

[0031] In this embodiment, the inner net 2 is installed on the indoor side of the frame 1, and the outer net 3 is installed on the outdoor side of the frame 1.

[0032] In this embodiment, the inner net 2 adopts an entire grid net with good ventilation effect.

[0033] In this embodiment, the size of the holes in the inner net 2 needs to be smaller than the size of mosquitoes and flies.

[0034] In this embodiment, the net block 31 is a flexible net with good ventilation effect.

[0035] In this embodiment, the size of the holes in the net block 31 needs to be smaller than the size of mosquitoes and flies.

[0036] In this embodiment, the screen window in the present utility model is an ecological screen window structure that can effectively capture mosquitoes and flies. It uses the livestock itself as the most effective trapping source and effectively kills mosquitoes and flies through the mosquito and fly catching screen window, thereby achieving the purpose of ecological environmental protection on the premise of effectively reducing the density of mosquitoes and flies around the breeding shed.

[0037] As Figure 2 、 Figure 4 and Figure 5 Collectively shown, the frame 1 includes a framework 11. Grooves 12 are provided on both side surfaces of the framework 11 and are arranged around the framework 11. The grooves 12 are square-shaped. The edges of the inner net 2 and the outer net 3 are both pressed tightly into the grooves 12 by the compression cotton 5. A cleaning port 13 is provided on the lower side of the inner peripheral surface of the framework 11, and the cleaning port 13 communicates the inside of the net cavity 4 with the outer side surface of the framework 11.

[0038] In this embodiment, the compression cotton 5 has elasticity.

[0039] In this embodiment, the width of the compression cotton 5 is slightly larger than the width of the groove 12, so that the compression cotton 5 can clamp and fix the edges of the inner net 2 and the outer net 3 and both ends of the support wire 34 inside the groove 12.

[0040] As Figure 2 and Figure 3 Collectively shown, the net blocks 31 are provided with flanges 33 on one side surface of the transverse gap 32. The flanges 33 are all arranged in the net cavity 4, and a transverse gap 32 is formed between every two adjacent flanges 33.

[0041] Among them, the transverse gaps 32 are all trumpet-shaped tapered openings with a wider outer width and a narrower inner width.

[0042] In this embodiment, the width of the transverse gap 32 gradually decreases from the outside to the inside.

[0043] In this embodiment, the trumpet-shaped transverse gap 32 is beneficial to guiding mosquitoes and flies outdoors into the net cavity 4.

[0044] In this embodiment, there is a gap greater than 15 millimeters between the end of the flange 33 and the inner net.

[0045] In this embodiment, the gap between the ends of the two flanges 33 is between 8 and 10 millimeters.

[0046] In this embodiment, the trumpet-shaped lateral gap 32 can ensure that when the mosquitoes and flies in the mesh cavity 4 move, they can smoothly enter the mesh cavity 4 through the lateral gap 32 and will not escape from the lateral gap 32. Thus, it is ensured that the mosquitoes and flies are trapped and die in the mesh cavity 4 and fall to the bottom of the mesh cavity 4.

[0047] Moreover, support lines 34 are provided at the bent portions of the flanges 33. The support lines 34 extend horizontally and are connected to the corresponding mesh blocks 31. Both ends of the support lines 34 are tightly arranged in the corresponding grooves 12 through pressing cotton 5.

[0048] In this embodiment, the setting of the support lines 34 increases the structural strength of the lateral gap 32 and ensures the fixation of the size of the lateral gap 32.

[0049] In addition, a cover 6 is installed at the outlet end of the cleaning port 13.

[0050] In this embodiment, the cover 6 is used to block the cleaning port 13.

[0051] The operation mode of the present utility model is as follows: First, the smell of livestock in the breeding shed is emitted to the outside through the screen window. Mosquitoes and flies will be induced by this smell and fly to the outside of the screen window. The mosquitoes and flies that fly to the outside of the screen window will want to enter the breeding shed through the screen window.

[0052] After that, the mosquitoes and flies gathered outside the outer net 3 constantly look for a channel to enter the breeding shed. Therefore, the mosquitoes and flies are guided by the lateral gap 32 and enter the mesh cavity 4.

[0053] Then, the mosquitoes and flies that enter the mesh cavity 4 are guided by the internal structure of the mesh cavity 4, are trapped inside the mesh cavity 4 and are difficult to fly out from the lateral gap 32 again, and finally are trapped and die inside the mesh cavity 4.

[0054] Finally, the mosquitoes and flies trapped and dead in the mesh cavity 4 fall into the cleaning port 13 at the bottom of the mesh cavity 4. The breeding personnel can open the cover 6 to clean the inside of the cleaning port 13.

[0055] In summary, the present utility model can block mosquitoes and flies from entering the inside of the breeding shed, and at the same time use the smell of livestock in the breeding shed as a trapping source to trap and kill mosquitoes and flies, breaking through the defect that the traditional screen window has a single effect of blocking mosquitoes and flies and the traditional device for trapping flying insects cannot trap mosquitoes because there is no effective trapping agent for mosquitoes. It fundamentally reduces the density of mosquitoes and flies around the breeding shed, and at the same time has a simple structure, is easy to implement, has a low cost, and causes no harm to the environment during the process of killing mosquitoes and flies.

[0056] Although embodiments of the present utility model have been shown and described, those skilled in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
