[0002] High-efficiency fans, also known as industrial fans, are fans specifically designed for ventilation and air exchange, as well as fire-fighting and high-temperature smoke extraction in tunnels, underground garages, high-end civil buildings, metallurgical plants, factories, and mines. They are mainly composed of components such as impellers, casings, inlet collectors, guide vanes, and motors.
[0003] In the field of high-efficiency fan technology, traditional high-efficiency fans have a fixed output airflow direction. The blades in the air distribution duct installed at the output end of the high-efficiency fan are fixed and cannot be adjusted. However, existing high-efficiency fans usually only have a simple air outlet direction adjustment function, which cannot achieve precise adjustment of airflow direction. This results in the airflow not being able to evenly cover the target area, which greatly reduces the ventilation and heat dissipation effect and affects production efficiency and equipment operation stability.
[0004] Given the problems of traditional high-efficiency fans, it is of great practical significance to develop a high-efficiency fan that can precisely adjust the direction and angle of the output airflow, is convenient and has a stable structure. The aim is to overcome the shortcomings of existing technologies and improve the overall performance and application value of high-efficiency fans. Utility Model Content
[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a high-efficiency and stable fan with precise angle adjustment, which can effectively solve the problem of airflow regulation in the existing technology.
[0006] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides a high-efficiency and stable fan with precise angle adjustment, including a high-efficiency fan body. A distribution duct is fixedly connected to the top of the high-efficiency fan body by bolts. It also includes a wind baffle assembly, which consists of a guide plate, a shaft, and a shaft. The guide plate is rotatably set inside the distribution duct via the shaft, and the shaft extends into a cavity groove. The cavity groove is opened in the side plate of the distribution duct. A shaft is fixedly connected to the outside of the shaft, and the teeth of the shaft mesh with the teeth of a rack. The rack is movably installed in the cavity groove.
[0007] According to some embodiments of the present invention, the rack is configured in two sets, and the two sets of racks are symmetrical about the staggered center axis of the shaft, and the width of the rack is equal to the thickness of the cavity groove.
[0008] According to some embodiments of the present invention, the windbreak assembly is configured in three groups, and the three groups of windbreak assemblies are equally spaced inside the air distribution pipe. The length of the windbreak assembly is equal to the length of the air distribution pipe, and the width of the three groups of windbreak assemblies is greater than the inner diameter of the air distribution pipe.
[0009] According to some embodiments of this utility model, the cavity groove and the limiting guide groove are connected in communication, the slider is externally fixedly connected to a rack, the slider is externally movably installed in the limiting guide groove, and the limiting guide groove is opened in the side plate of the air distribution pipe.
[0010] According to some embodiments of this utility model, the limiting guide groove and the notch are connected in communication, and a toggle block is movably connected inside the notch, with the end of the toggle block fixed to the outside of the slider.
[0011] According to some embodiments of the present invention, a bayonet groove is provided in the notch, a plug-in block is inserted into the bayonet groove, the plug-in block is externally movably connected to a spring groove, the spring groove is opened on the outside of the toggle block, and a compression spring is provided in the spring groove.
[0012] According to some embodiments of the present invention, the cross-section of the limiting guide groove is a "convex" shaped structure, and the limiting guide groove is configured in two sets, with the two sets of limiting guide grooves being symmetrical about the central axis of the cavity groove.
[0013] According to some embodiments of the present invention, the bayonet groove is a U-shaped groove, and the bayonet groove is configured in multiple groups, with the multiple groups of bayonet grooves evenly distributed at equal intervals within the notch.
[0014] Beneficial effects The technical solution provided by this utility model has the following advantages compared with the known prior art: 1. By movably installing a rack in the cavity groove, the teeth of the rack mesh with the teeth of the shaft. When the rack moves left and right in the cavity groove, it drives the shaft to rotate in the cavity groove. The shaft is fixed to the outside of the shaft. Therefore, the rotation of the shaft drives the shaft to drive the air guide plate to rotate in the air distribution duct. Thus, the angle of the air guide plate in the air distribution duct is adjustable. When the high-efficiency fan body is started, the angle adjustment of the air guide plate adjusts the airflow direction output by the air distribution duct. When the high-efficiency fan body is started, adjusting the angle of the wind deflector component helps to change the airflow direction output by the air distribution duct.
[0015] 2. By fixing the end of the actuating block to the slider, the actuating block is movably set in the notch. When the actuating block is moved, the position of the slider in the limiting guide groove can be adjusted. Therefore, by moving the actuating block, the slider can drive the rack to adjust in the cavity groove. As a result, the rack drive shaft rotates in the cavity groove, changing the angle of the wind baffle assembly in the air distribution pipe. The spring force of the compression spring pushes the plug-in block to be inserted into the bayonet groove, thus making the actuating block firmly locked in the notch. Therefore, the position of the slider in the limiting guide groove is locked, and the angle of the wind baffle assembly in the air distribution pipe is locked. This is beneficial to stabilizing the airflow direction output by the high-efficiency fan body through the air distribution pipe. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0020] The present invention will be further described below with reference to the embodiments.
[0021] See attached document Figure 1-8 A high-efficiency and stable fan with precise angle adjustment includes a high-efficiency fan body 1, a gear 32, and a distribution duct 2 bolted to the top of the high-efficiency fan body 1. It also includes a windbreak assembly 3, which consists of a guide plate 31, a gear 32, and a shaft 33. The guide plate 31 is rotatably mounted inside the distribution duct 2 via the shaft 33, and the shaft 33 extends into a cavity groove 5 located within the side plate of the distribution duct 2. The gear 32 is fixedly connected to the outside of the shaft 33, and the teeth of the gear 32 mesh with the teeth of a rack 8, which is movably mounted. Within the cavity 5, a rack 8 is movably installed within the cavity 5, and the teeth of the rack 8 mesh with the teeth of the gear 32. When the rack 8 moves left and right within the cavity 5, it drives the gear 32 to rotate within the cavity 5. The gear 32 is fixed to the outside of the shaft 33. Therefore, the rotation of the gear 32 drives the shaft 33 to rotate the air guide plate 31 within the air distribution duct 2. Thus, the angle of the air guide plate 31 within the air distribution duct 2 is adjustable. When the high-efficiency fan body 1 is started, the angle adjustment of the air guide plate 31 adjusts the airflow direction output from the air distribution duct 2.
[0022] According to some embodiments of this utility model, the gear 32 and rack 8 are configured in two sets, and the two sets of rack 8 are symmetrical about the staggered central axis of the gear 32. The width of the rack 8 is equal to the thickness of the cavity groove 5. By staggering and symmetrically arranging the rack 8 about the central axis of the gear 32, the gear 32 can rotate stably when the rack 8 drives the gear 32 to rotate.
[0023] According to some embodiments of this utility model, the gear 32 wind deflector assembly 3 is configured in three groups, and the three groups of wind deflector assemblies 3 are equally spaced inside the air distribution pipe 2. The length of the wind deflector assembly 3 is equal to the length of the air distribution pipe 2, and the width of the three groups of wind deflector assemblies 3 is greater than the inner diameter of the air distribution pipe 2. By equally spaced wind deflector assemblies 3 inside the air distribution pipe 2, when the high-efficiency fan body 1 is started, adjusting the angle of the wind deflector assembly 3 is beneficial to changing the airflow direction output from the air distribution pipe 2.
[0024] In the above technical solution, the rack 8 is movably installed in the cavity groove 5, and the teeth of the rack 8 mesh with the teeth of the gear 32. When the rack 8 moves left and right in the cavity groove 5, it can drive the gear 32 to rotate in the cavity groove 5. The gear 32 is fixed outside the shaft 33. Therefore, the rotation of the gear 32 drives the shaft 33 to drive the air guide plate 31 to rotate in the air distribution pipe 2. Thus, the angle of the air guide plate 31 in the air distribution pipe 2 is adjustable. When the high-efficiency fan body 1 is started, the angle adjustment of the air guide plate 31 adjusts the airflow direction output by the air distribution pipe 2. The rack 8 is staggered and symmetrically arranged about the central axis of the gear 32. When the rack 8 drives the gear 32 to rotate, it can make the gear 32 rotate stably. The wind baffle assembly 3 is evenly spaced in the air distribution pipe 2. When the high-efficiency fan body 1 is started, adjusting the angle of the wind baffle assembly 3 is beneficial to changing the airflow direction output by the air distribution pipe 2.
[0025] According to some embodiments of this utility model, the cavity groove 5 and the limiting guide groove 6 are connected in communication. The slider 7 is externally fixedly connected to a rack 8, and the slider 7 is externally movably installed in the limiting guide groove 6. The limiting guide groove 6 is opened in the side plate of the air distribution pipe 2. By externally fixing the slider 7 to the rack 8, and then movably setting the slider 7 in the limiting guide groove 6, when the slider 7 moves in the limiting guide groove 6, the rack 8 is driven to adjust its position left and right in the cavity groove 5.
[0026] According to some embodiments of this utility model, the gear 32 is connected to the limiting guide groove 6 and the notch 9. The notch 9 is movably connected to the actuating block 10. The end of the actuating block 10 is fixed to the outside of the slider 7. By fixing the end of the actuating block 10 to the slider 7, the actuating block 10 is movably disposed in the notch 9. When the actuating block 10 is actuated, the position of the slider 7 in the limiting guide groove 6 can be adjusted. Therefore, by actuating the actuating block 10, the slider 7 can drive the rack 8 to adjust in the cavity groove 5. Thus, the rack 8 drives the gear 32 to rotate in the cavity groove 5, changing the angle of the windbreak assembly 3 in the air distribution pipe 2.
[0027] According to some embodiments of this utility model, a bayonet groove 4 is provided in the notch 9 of gear 32, and a plug-in block 13 is inserted into the bayonet groove 4. The plug-in block 13 is externally movably connected to the spring groove 11. The spring groove 11 is located on the outside of the actuating block 10, and a compression spring 12 is provided in the spring groove 11. The spring force of the compression spring 12 pushes the plug-in block 13 into the bayonet groove 4, thus making the actuating block 10 securely locked in the notch 9. Therefore, the position of the slider 7 in the limiting guide groove 6 is locked, so that the angle of the windproof component 3 in the air distribution pipe 2 is locked, which is beneficial to the stabilization of the airflow direction output by the high-efficiency fan body 1 through the air distribution pipe 2.
[0028] According to some embodiments of the present utility model, the cross-section of the limiting guide groove 6 of the gear 32 is in a "convex" shape structure. There are two groups of the limiting guide grooves 6, and the two groups of limiting guide grooves 6 are axially symmetric about the center of the cavity groove 5. By setting the cross-section of the limiting guide groove 6 in a "convex" shape structure, the slider 7 is thus firmly positioned in the limiting guide groove 6.
[0029] According to some embodiments of the present utility model, the bayonet slot 4 of the gear 32 is in a square-shaped slot. There are multiple groups of the bayonet slots 4, and the multiple groups of bayonet slots 4 are evenly distributed at equal intervals in the notch 9. Setting the bayonet slots 4 at equal intervals in the notch 9 is beneficial for changing the position of the plug-in block 13 in the bayonet slot 4. When the plug-in block 13 is inserted into the bayonet slots 4 at different positions, the adjustment angle of the wind shield assembly 3 in the air duct 2 is different.
[0030] In the above technical solution, the external of the slider 7 is fixedly connected to the rack 8, and then the slider 7 is movably arranged in the limiting guide groove 6. When the slider 7 moves in the limiting guide groove 6, it drives the rack 8 to adjust its position left and right in the cavity groove 5. The end of the拨动块10 is fixed to the slider 7, and the拨动块10 is movably arranged in the notch 9. When the拨动块10 is toggled, the position of the slider 7 in the limiting guide groove 6 can be adjusted. Therefore, by toggling the拨动块10, the slider 7 can be made to drive the rack 8 to adjust in the cavity groove 5. Thus, the rack 8 drives the gear 32 to rotate in the cavity groove 5, changing the angle of the wind shield assembly 3 in the air duct 2. By the elastic force of the compression spring 12, the plug-in block 13 is pushed to be inserted into the bayonet slot 4. Therefore, the拨动块10 is firmly locked in the notch 9, and thus the position of the slider 7 in the limiting guide groove 6 is locked, so that the angle of the wind shield assembly 3 in the air duct 2 is locked, which is beneficial for stabilizing the air flow direction output by the high-efficiency fan body 1 through the air duct 2.
[0031] It should be noted that there is an unclear "拨动块10" in the original text which may need to be further clarified for a more accurate translation. Here it is directly translated as "拨动块10" for the time.Working principle: By movably installing rack 8 in cavity groove 5, the teeth of rack 8 mesh with the teeth of gear 32. When rack 8 moves left and right in cavity groove 5, it drives gear 32 to rotate in cavity groove 5. Gear 32 is fixed outside shaft 33. Therefore, the rotation of gear 32 drives shaft 33 to drive air guide plate 31 to rotate in air distribution pipe 2. Thus, the angle of air guide plate 31 in air distribution pipe 2 is adjustable. When the high-efficiency fan body 1 is started, the angle adjustment of air guide plate 31 adjusts the airflow direction output from air distribution pipe 2. The rack 8 is symmetrically arranged about the central axis of gear 32. When rack 8 drives gear 32 to rotate, it can make gear 32 rotate stably. The wind baffle assembly 3 is evenly spaced in air distribution pipe 2. When the high-efficiency fan body 1 is started, adjusting the angle of the wind deflector component 3 helps to change the airflow direction output by the air distribution pipe 2. When the toggle block 10 is moved, the position of the slider 7 in the limiting guide groove 6 can be adjusted. Therefore, by moving the toggle block 10, the slider 7 can drive the rack 8 to adjust in the cavity groove 5. Thus, the rack 8 drives the gear 32 to rotate in the cavity groove 5, changing the angle of the wind deflector component 3 in the air distribution pipe 2. The spring force of the compression spring 12 pushes the insertion block 13 to insert into the bayonet groove 4, thus making the toggle block 10 firmly locked in the notch 9. Therefore, the position of the slider 7 in the limiting guide groove 6 is locked, so the angle of the wind deflector component 3 in the air distribution pipe 2 is locked, which helps to stabilize the airflow direction output by the high-efficiency fan body 1 through the air distribution pipe 2.
[0032] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
