[0029] 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.

[0030] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely illustrates some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model. It should be noted that, unless otherwise specified, the embodiments, features, and technical solutions in the embodiments of this utility model can be combined with each other.

[0031] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0032] like Figures 1-10As shown, this embodiment proposes an adjustable blower suction mechanism, including a suction cylinder 1 and a filter 2. The filter 2 is installed at the rear end of the suction cylinder 1, and the suction cylinder 1 with the filter 2 installed is fixed to the suction end of the blower by four sets of screws and shock absorbers.

[0033] In the initial stage of installation, the air inlet radius of the air intake of the air cylinder 1 is the smallest. The air volume regulating plates 3 are attached to each other and arranged in a ring array. The shape of the air volume regulating plate 3 is centered on one side as an axis, and the other side extends outward with a certain curvature in a centrifugal motion. The air volume regulating plate 3 bulges outward on the air intake side to facilitate airflow. The linkage groove 10 runs through the inner and outer surfaces of the air intake 1. The rotating shaft end of the air volume regulating plate 3 is wrapped around the outer end of the positioning shaft 5. The positioning shaft 5 is fixed in the positioning groove 4. The positioning groove 4 is arranged in a ring array on the inner surface of the air intake 1. The rotation of the air volume regulating plate 3 is limited by the positioning shaft 5 and the positioning groove 4. The leeward end of the air volume regulating plate 3 is fixedly connected to the linkage rod 6. The outer end of the linkage rod 6 is wrapped with a hinge ring. Each set of hinge rings is movably connected to a pair of hinge pieces 8. The outer ends of the same pair of hinge pieces 8 are fixed to one end of different telescopic rods 7. The connection of the telescopic rod 7, the hinge pieces 8 and the hinge rings forms a closed loop.

[0034] like Figures 8-9 As shown, in a preferred embodiment, based on the above method, further, when it is necessary to adjust the air inlet radius of the air inlet of the air cylinder 1, first push the linkage ring 14 located at the outer end of the air cylinder 1. The inner end of the linkage ring 14 is movably connected to the rotating locking rod 15. Multiple sets of locking grooves 16 are evenly spaced on the surface of the air cylinder 1. The linkage ring 14 moves up and down along the linkage groove 10. Multiple sets of rotating locking rods 15 are arranged in a ring array along the linkage ring 14. The rotating locking rods 15 are engaged with each ring of locking grooves 16 in sequence. Multiple rings of locking grooves 16 are provided. The multiple rings of locking grooves 16 are evenly spaced along the outer surface of the air cylinder 1. The linkage ring 14 moves a certain distance, and the rotating locking rods 15 located at the outer end of the linkage ring 14 are engaged in the corresponding locking grooves 16 respectively.

[0035] like Figures 3-7 and Figure 10As shown, in a preferred embodiment, based on the above method, further, during the movement of the linkage ring 14, the tail end of the linkage rope 9 fixedly connected to the lower end of the linkage ring 14 is pulled. The sliding of the linkage rope 9 passes through the inner and outer surfaces of the air intake cylinder 1 via the linkage groove 10. The air intake cylinder 1 has a ring array of linkage grooves 10 running through its casing. The leeward end of the air volume regulating plate 3 is provided with a linkage rod 6, which is movably connected to the linkage rope 9. The air volume regulating plate 3 is connected to multiple sets of linkage rods 6 respectively. The inner side of the air intake end of the air intake cylinder 1 is provided with a ring array of air volume regulating plates 3. A positioning shaft 5 and a positioning groove 4 for rotation at the origin are provided between the air volume regulating plate 3 and the air intake cylinder 1. When the air volume regulating plate 3 rotates, it is positioned according to the positioning groove 4 and the positioning shaft 5. The air volume regulating plates 3 are also connected to each other through hinges 8 and telescopic rods 7. The linkage rods 6 are provided with hinges 8 and telescopic rods 7. The telescopic rod 7 is a combination of an inner sliding rod and an outer sliding cylinder. The telescopic rod 7 is designed to ensure the stable connection between multiple sets of air volume regulating plates 3. The inner end of the linkage rope 9 is provided with a sliding rod 12, a linkage spring 11, and a positioning ring 13. A groove is provided in the center of the linkage rope 9. The sliding rod 12 is installed in the groove. The linkage spring 11 is wrapped around the outer end of the sliding rod 12. The upper end of the linkage spring 11 is fixedly connected to the positioning ring 13. The positioning ring 13 is fixed in the linkage groove 10 and sleeved on the outer end of the sliding rod 12. The outer end of the linkage rope 9 is fixedly fixed on the linkage ring 14. When the linkage rope 9 is stretched, the linkage spring 11 in the center of the linkage rope 9 is limited by the positioning ring 13, which compresses the linkage spring 11 on the outside of the sliding rod 12 and the inner end of the groove. This further ensures the stable engagement between the rotating clamp 15 and the groove 16 and prevents the rotating clamp 15 from disengaging from the groove 16.

[0036] The movement of the linkage can be controlled by adding a cylinder and connecting it to a control system to control the distance of movement;

[0037] The movement of the linkage rope 9 can only be achieved through the movement of the linkage ring. When stationary, the linkage rope 9 is fixed by the compression of the linkage spring and the positioning ring, and will not push the rotation of the air volume adjustment plate as the wind moves inward along the air inlet.

[0038] When this application is used:

[0039] Install filter 2 at the rear end of air intake 1, and then fix air intake 1 with filter 2 installed to the air intake end of blower with four sets of screws and shock absorbers.

[0040] In the initial stage of installation, the air inlet radius of the air intake of the air cylinder 1 is the smallest. The air volume adjustment plates 3 are attached to each other and arranged in a ring array. When it is necessary to adjust the air inlet radius of the air intake of the air cylinder 1, the linkage ring 14 located at the outer end of the air cylinder 1 is pushed first. The linkage ring 14 moves a certain distance, and the rotating locking rod 15 located at the outer end of the linkage ring 14 is respectively locked in the corresponding locking groove 16.

[0041] During the movement of the linkage ring 14, the tail end of the linkage rope 9, which is fixedly connected to the lower end of the linkage ring 14, is pulled. The sliding of the linkage rope 9 passes through the inner and outer surfaces of the air intake cylinder 1 via the linkage groove 10 and is connected to the air volume adjustment plate 3 by multiple sets of linkage rods 6. When the air volume adjustment plate 3 rotates, it is positioned according to the positioning groove 4 and the positioning shaft 5. The air volume adjustment plates 3 are also connected to each other by the hinge 8 and the telescopic rod 7. The telescopic rod 7 is a combination of an inner sliding rod and an outer sliding cylinder. The telescopic rod 7 is set to ensure the stable connection between the multiple sets of air volume adjustment plates 3. When the linkage rope 9 is stretched, the linkage spring 11 at the center of the linkage rope 9 is limited by the positioning ring 13, which compresses the linkage spring 11 on the outside of the sliding rod 12 and the inside of the groove, further ensuring the stable engagement between the rotating clamp rod 15 and the clamp groove 16 and preventing the rotating clamp rod 15 from disengaging from the clamp groove 16.

[0042] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the utility model, are covered within the scope of the claims of the present utility model.
