Abstract
Description
Technical Field
[0001] This utility model belongs to the field of airflow diffuser technology, and specifically relates to a high-efficiency airflow uniform diffuser device. Background Technology
[0002] Uniform airflow diffusers are key devices used to transform high-speed / non-uniform airflow into a stable, uniform flow field, and are widely used in HVAC systems, industrial burners, wind tunnel experiments, clean rooms, and other fields. Their core objectives are to reduce turbulence, eliminate velocity gradients, and minimize pressure loss.
[0003] A utility model patent with patent authorization announcement number CN206823488U discloses an airflow diffuser. The key technical points of the solution are: it includes an annular end cap and a base, a metal mesh for diffused airflow is provided between the end cap and the base, and rings are provided on the opposite surfaces of the end cap and the base. The metal mesh is fitted on the two rings. A protrusion is provided on the inner ring of the end cap, and a fixing rod is provided on the base. The fixing rod passes through the protrusion and is fixed to the protrusion.
[0004] However, existing airflow uniform diffuser devices also have certain drawbacks. Although existing airflow uniform diffuser devices use components such as filters to remove particulate impurities such as dust in the fluid air, due to the adhesion characteristics of impurities, the filters are prone to clogging after long-term use, which in turn causes poor airflow. Summary of the Invention
[0005] The purpose of this invention is to provide a high-efficiency airflow uniform diffuser device, which solves the problem that although existing airflow uniform diffuser devices use components such as filters to remove dust and other particulate impurities from the fluid air, the filters are prone to clogging due to the adhesion characteristics of impurities, resulting in poor airflow.
[0006] To achieve the above objectives, this utility model provides a high-efficiency airflow uniform diffuser device, including a mounting cylinder. A diffuser disk is threadedly connected to the outer side of the mounting cylinder. The surface of the diffuser disk has multiple flow holes arranged in a ring array. A ventilation fan is installed inside the mounting cylinder. A flow mechanism is installed on the mounting cylinder. A support shaft is rotatably connected to the inner wall of the mounting cylinder. Two evenly distributed rotating columns are fixedly sleeved on the outer side of the support shaft. Each rotating column is rotatably connected to the mounting cylinder. An insertion hole is opened on the surface of the left rotating column. A mounting plate is fixedly connected to the left side of the mounting cylinder and above the rotating column. A connecting plate is slidably connected to the inner wall of the mounting plate. An insertion post is fixedly connected to the lower end of the connecting plate. The insertion post is slidably connected to the insertion hole. An end plate is fixedly connected to the upper end of the connecting plate.
[0007] The principle of this utility model is as follows: by pulling the end plate upward, the connecting piece slides stably along the inner wall of the mounting piece, causing the spring to deform and drive the insertion post upward, eventually causing the insertion post to disengage from the insertion hole. This allows the rotating column to be pulled to rotate, thereby driving the support shaft to rotate, which in turn causes the air guide vane to deflect, adaptively adjusting the airflow direction. When the end plate is released, the spring returns to its original deformation, pulling the insertion post to insert into the next insertion hole, limiting the rotating column, and thus stabilizing the air guide vane.
[0008] By using a filter, dust and other particulate impurities in the circulating air can be removed. Pulling the handle upwards causes the telescopic rod to slide along the inner wall of the fixed plate, deforming the second spring and causing the moving ring to move upwards, disengaging from the limiting plate. As the moving ring moves, it moves the filter. When the handle is released, the second spring returns to its original shape, pulling the telescopic rod downwards and causing the moving ring to move downwards as well. This causes the moving ring to contact and collide with the limiting plate, resulting in the filter vibrating and removing dust, thus ensuring good air circulation efficiency.
[0009] The beneficial effects of this utility model are as follows: This solution, through the setting of a ventilation fan and a diffuser plate, can uniformly diffuse airflow. Under the action of the support shaft and the rotating column, the position of the air guide can be adjusted. Under the action of the insertion hole, the insertion post, and the spring, the rotating post can be inserted and used, so that the air guide after the position is adjusted is stable, thereby controlling the airflow direction. Through the setting of the filter screen, dust and other particulate impurities in the circulating air can be filtered out, avoiding impact on the ventilation fan and other components. The handle can be pulled to move the telescopic rod, so that the moving ring moves the filter screen. With the action of the spring and the limiting plate, the filter screen can vibrate to remove dust, so as to ensure good airflow through the filter screen and thus ensure the high efficiency of airflow.
[0010] Furthermore, multiple sockets are provided, and the multiple sockets are arranged in a circular array on the left rotating column. The sockets are designed to facilitate insertion and use with the column.
[0011] Furthermore, a spring is provided on the outer side of the connecting piece. One end of the spring is welded to the end plate, and the other end of the spring is welded to the mounting piece. The end plate can be connected and used by the spring.
[0012] Furthermore, multiple air guide vanes are mounted on the lower end of the support shaft via a support plate. These multiple air guide vanes are evenly distributed on the support plate of the support shaft, and the airflow can be guided by the air guide vanes.
[0013] Furthermore, the circulation mechanism includes a fixing plate, a fixing plate fixedly connected to the upper end of the mounting cylinder, a telescopic rod slidably connected to the inner wall of the fixing plate, a handle fixedly connected to the upper end of the telescopic rod, a moving ring fixedly connected to the lower end of the telescopic rod, the moving ring slidably connected to the mounting cylinder, a filter screen fixedly connected to the inner wall of the moving ring, a limiting plate fixedly connected to the inner wall of the mounting cylinder, the limiting plate contacting the moving ring, and a second spring provided on the outer side of the telescopic rod. Through the filter screen, impurities in the circulating air can be filtered out, and under the action of the handle, the second spring, the limiting plate, and other components, the filter screen can vibrate to remove dust.
[0014] Furthermore, four limiting plates are provided, and the four limiting plates are arranged in a circular array on the mounting cylinder. By setting the limiting plates, the moving ring can be limited.
[0015] Furthermore, one end of the second spring is welded to the handle, and the other end of the second spring is welded to the fixing plate. The handle can be connected and used through the setting of the second spring. Attached Figure Description

Detailed Implementation
[0022] The implementation examples are basically as follows Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, this embodiment provides a high-efficiency airflow uniform diffuser device, including a mounting cylinder 1. A diffuser disk 2 is threadedly connected to the outer side of the mounting cylinder 1. The surface of the diffuser disk 2 has multiple flow holes arranged in a ring array. A ventilation fan 3 is provided inside the mounting cylinder 1. A support shaft 5 is rotatably connected to the inner wall of the mounting cylinder 1. Two evenly distributed rotating columns 6 are fixedly sleeved on the outer side of the support shaft 5. Each rotating column 6 is rotatably connected to the mounting cylinder 1. An insertion hole 7 is provided on the surface of the left rotating column 6. A mounting plate 8 is fixedly connected to the left side of the mounting cylinder 1 and above the rotating column 6. A connecting plate 9 is slidably connected to the inner wall of the mounting plate 8. An insertion post 10 is fixedly connected to the lower end of the connecting plate 9. The insertion post 10 is slidably connected to the insertion hole 7. An end plate 11 is fixedly connected to the upper end of the connecting plate 9.
[0023] like Figure 1 , Figure 2 , Figure 3 As shown, multiple insertion holes 7 are provided, arranged in a circular array on the left rotating column 6. The insertion holes 7 facilitate insertion with the insertion column 10. A spring 12 is provided on the outer side of the connecting piece 9. One end of the spring 12 is welded to the end plate 11, and the other end of the spring 12 is welded to the mounting piece 8. The end plate 11 can be connected by the spring 12. Multiple air guide vanes 13 are installed on the lower end of the support shaft 5 through the support piece. The multiple air guide vanes 13 are evenly distributed on the support piece of the support shaft 5. The air guide vanes 13 can guide the airflow.
[0024] like Figure 1 , Figure 2 , Figure 4 As shown, a flow mechanism 4 is provided on the mounting cylinder 1. The flow mechanism 4 includes a fixing plate 40. The fixing plate 40 is fixedly connected to the upper end of the mounting cylinder 1. A telescopic rod 41 is slidably connected to the inner wall of the fixing plate 40. A handle 42 is fixedly connected to the upper end of the telescopic rod 41. A moving ring 43 is fixedly connected to the lower end of the telescopic rod 41. The moving ring 43 is slidably connected to the mounting cylinder 1. A filter screen 44 is fixedly connected to the inner wall of the moving ring 43. A limiting piece 45 is fixedly connected to the inner wall of the mounting cylinder 1. The limiting piece 45 contacts the moving ring 43. A second spring 46 is provided on the outer side of the telescopic rod 41. Through the setting of the filter screen 44, impurities in the flowing air can be filtered out. Under the action of the handle 42, the second spring 46, the limiting piece 45 and other components, the filter screen 44 can be vibrated to remove dust.
[0025] like Figure 1 , Figure 2 , Figure 4As shown, four limiting plates 45 are provided, and the four limiting plates 45 are arranged in a ring array on the mounting cylinder 1. By setting the limiting plates 45, the moving ring 43 can be limited. One end of the second spring 46 is welded to the handle 42, and the other end of the second spring 46 is welded to the fixing plate 40. By setting the second spring 46, the handle 42 can be connected.
[0026] The specific implementation process of this utility model is as follows: By pulling the end plate 11 upward, the connecting piece 9 is driven to slide stably along the inner wall of the mounting piece 8, causing the spring 12 to deform and drive the insertion post 10 to move upward, so that the insertion post 10 is disengaged from the insertion hole 7. The rotating column 6 can be pulled to rotate, thereby driving the support shaft 5 to rotate, and then driving the air guide 13 to deflect, making adaptive adjustments to the airflow direction. When the end plate 11 is released, the spring 12 returns to its deformation, so that the insertion post 10 is pulled to insert into the next insertion hole 7, limiting the rotating column 6, thereby making the air guide 13 stable.
[0027] By setting the filter screen 44, dust and other particulate impurities in the circulating air can be filtered out. Pulling the handle 42 upward will cause the telescopic rod 41 to slide along the inner wall of the fixed plate 40, causing the second spring 46 to deform and drive the moving ring 43 upward, so that the moving ring 43 disengages from the limiting plate 45. When the moving ring 43 moves, it can drive the filter screen 44 to move. When the handle 42 is released, the second spring 46 will return to its deformation, pulling the telescopic rod 41 downward and driving the moving ring 43 downward, so that the moving ring 43 contacts and impacts the limiting plate 45, thereby causing the filter screen 44 to vibrate and remove dust, so as to ensure good air circulation efficiency.
[0028] This solution, through the setting of ventilation fan 3 and diffuser plate 2, can uniformly diffuse airflow. Under the action of support shaft 5 and rotating column 6, the position of air guide vane 13 can be adjusted. With the action of insertion hole 7, insertion post 10, spring 12 and other structures, the rotating column 6 can be inserted and used, so that the air guide vane 13 after adjustment is stable, thereby controlling the airflow direction. Through the setting of filter screen 44, dust and other particulate impurities in the circulating air can be filtered out to avoid affecting components such as ventilation fan 3. Pulling handle 42 can move telescopic rod 41, so that moving ring 43 can move filter screen 44. With the action of spring 2 46, limiting plate 45 and other structures, filter screen 44 can vibrate to remove dust, so as to ensure good airflow through filter screen 44, thereby ensuring efficient airflow.
