DETAILED DESCRIPTION

[0033] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0034] Referring to Figures 1-2 The utility model provides an embodiment: a kind of for the installation of air curtain machine prevents insect structure, including main body 1, fan 2 is provided in main body 1 inside, protective screen 3 is slidably connected in main body 1 inside, the side wall of protective screen 3 is fixedly connected with fixed block one 4, fixed block one 4 side wall is slidably connected in main body 1 inside, fixed mechanism is provided in the side wall of main body 1 for installing protective screen 3, adjusting assembly is provided in the lower surface of main body 1;

[0035] Fixed mechanism includes fixed shell 5, the side wall of fixed shell 5 is fixedly connected in the side wall of main body 1, fixed rod 9 is fixedly connected in the inside of fixed shell 5, spring 10 is sleeved in the side wall of fixed rod 9, sliding sleeve 11 is slidably connected in the side wall of fixed rod 9, rotating strip 8 is rotatably connected in the side wall of sliding sleeve 11, press column 6 is slidably connected in the inside of fixed shell 5, rotating strip 8 one end is rotatably connected in the inside of press column 6, handle 7 is fixedly connected on the upper surface of press column 6, clamping column 12 is fixedly connected in one end of sliding sleeve 11, spring 10 one end is fixedly connected in the inside of fixed shell 5, spring 10 other end is fixedly connected in the side wall of sliding sleeve 11, the side wall of clamping column 12 is slidably connected in the inside of protective screen 3, the side wall of clamping column 12 is slidably connected in the inside of fixed block one 4;

[0036] When using the device to work, first, start fan 2 to make it produce powerful airflow, which is sprayed from air outlet to form an air barrier. This barrier can effectively block the entry of insects and other small particles. When the protective screen 3 needs to be cleaned, the operator first holds the handle 7 firmly and presses it with appropriate force. This action directly causes the press column 6 to move downward along the predetermined track. As the press column 6 moves downward, it effectively presses the rotating strip 8, causing the rotating strip 8 to rotate. The rotation of the rotating strip 8 is converted into the sliding power of the sliding sleeve 11 along the track. The sliding sleeve 11 starts to move along the set path, causing the spring 10 to compress under external force. At the same time, the sliding action of the sliding sleeve 11 causes the clamping column 12 to be extracted from the protective screen 3, which is embedded in the protective screen 3. This causes the fixed state of the protective screen 3 to be released. When the clamping column 12 is completely separated from the protective screen 3, the protective screen 3 loses its original fixed support. At this time, maintenance personnel can easily remove it, providing convenience for subsequent deep cleaning and ensuring the continuous and efficient operation of the device. Through the cleaning of the protective screen 3, the service life of the device is extended, and it is ensured that it is always in the best state.

[0037] Referring to Figures 3-5 , the adjusting assembly comprises an adjusting louver 13 rotatably connected to the inside of the main body 1, a fixed plate 14 fixedly connected to the side wall of the adjusting louver 13, a connecting plate 15 rotatably connected to the side wall of the fixed plate 14, a fixed sleeve 17 fixedly connected to the lower surface of the main body 1, a motor 18 fixedly connected to the side wall of the fixed sleeve 17, a worm 19 fixedly connected to the output end of the motor 18, the worm 19 rotatably connected to the inside of the fixed sleeve 17, a rotating rod 20 rotatably connected to the inside of the fixed sleeve 17, a worm gear 21 fixedly connected to the side wall of the rotating rod 20, the worm gear 21 meshing with the worm 19, a gear 22 fixedly connected to the side wall of the rotating rod 20, a rack 23 slidably connected to the inside of the fixed sleeve 17, the rack 23 meshing with the gear 22, and a fixed block two 16 fixedly connected to the inside of the connecting plate 15.

[0038] When the wind direction needs to be adjusted to achieve the best air supply effect, first start the motor 18 to drive the connected worm 19 to rotate, so that the worm gear 21 starts to rotate under the drive of the worm 19, and in turn drives the rotating rod 20 fixedly connected coaxially therewith to start rotating, the rotation of the rotating rod 20 drives the gear 22 to rotate, and due to the meshing of the gear 22 and the rack 23, the rotary motion is converted into linear motion, so that the rack 23 smoothly slides along the set track, the sliding of the rack 23 drives the fixed block 16 connected thereto to move, and at the same time, through the guidance of the connecting plate 15, the rotation of the fixed plate 14 drives the adjusting louver 13 to adjust the angle, the rotation of the adjusting louver 13 not only changes the air supply direction, but also adjusts the air volume as needed to realize the adjustment of the air speed. This series of mechanical movements realizes the adjustment of the wind direction and meets the diversified needs of the air supply direction and air volume in different scenes.

[0039] Working principle: when using the device to work, first start the fan 2 to generate strong airflow, which is sprayed from the air outlet to form an air barrier. This barrier can effectively block the entry of insects and other small particles. When the protective net 3 needs to be cleaned, first press the handle 7 to push the pressing column 6 down, extrude the rotating rod 8 to make it rotate, thereby pushing the sliding sleeve 11 to slide, extruding the spring 10 to make it contract, and at the same time, the sliding of the sliding sleeve 11 pulls out the clamping column 12 from the inside of the protective net 3, at this time the protective net 3 loses the fixation and can be taken down for cleaning. When the wind direction needs to be adjusted, first start the motor 18 to drive the worm 19 to rotate, so that the worm gear 21 meshing therewith drives the rotating rod 20 to start rotating, thereby making the gear 22 rotate and push the rack 23 meshing therewith to slide, and in turn make the fixed block 16 drive the connecting plate 15 to slide, through the rotation of the fixed plate 14, the adjusting louver 13 is rotated to achieve the effect of adjusting the wind direction.

[0040] It should be pointed out finally that: the above only for the preferred embodiments of the utility model have, and do not for limiting the utility model, although the utility model has been described in detail with reference to the foregoing embodiments, for the person skilled in the art, it still can modify the technical scheme recorded in the foregoing each embodiment, or equivalent replacement to part of technical features, any modification, equivalent replacement, improvement etc. that is made within the spirit and principles of the utility model, should be included in the protection scope of the utility model.
