Description

Technical Field

[0001] This utility model relates to the field of impeller technology, and in particular to an impeller that increases strength and airflow. Background Technology

[0002] An impeller is a wheel disk equipped with moving blades (blades), which is often used in ventilation fans. When the impeller rotates at high speed, it generates kinetic energy. The air in the flow channel between the blades is compressed and accelerated by this kinetic energy, turning into airflow and generating wind power.

[0003] The existing blades are all individually designed and made relatively thin, with a thickness of 4-7mm. Blades with this structure have low strength and poor rigidity, which cannot meet the structural strength support at high speeds and can only rotate at low intensity. Therefore, the impeller cannot generate a large air volume. Utility Model Content

[0021] The following is in conjunction with the appendix Figure 1 To be continued Figure 6 The present invention will be further described in detail below, along with specific embodiments.

[0022] like Figures 1 to 2As shown, an impeller for increasing strength and airflow includes a top cover 1 and a base 2. The top cover 1 and the base 2 are coaxially arranged. A plurality of blades 3 are arranged between the top cover 1 and the base 2. The plurality of blades 3 are arranged in a circular array with the center of the top cover 1 as the center point. The plurality of blades 3 are inclined at 40 degrees to 60 degrees. The top cover 1 is provided with a first connecting part 11. The base 2 is provided with a second connecting part 21. The blades 3 are provided with an upper end face 31 and a lower end face 32. The upper end face 31 of the blades 3 is fixedly connected to the first connecting part 11 of the top cover 1. The lower end face 32 of the blades 3 is fixedly connected to the second connecting part 21 of the base 2. A reinforcing rib groove 33 is provided in the middle of the blades 3.

[0023] In this embodiment, a reinforcing rib groove 33 is pressed into the middle of the blade 3. The reinforcing rib groove 33 improves the strength of the blade 3 itself, so that the blade 3 can meet the structural strength support at high speed. As the impeller speed increases, the air volume increases.

[0024] like Figures 3 to 6 As shown, in this embodiment, the first connecting part 11 of the top cover 1 is provided with a first slot 12, and the upper end face 31 of the blade 3 is provided with a first locking block 311, which engages with the first slot 12; the second connecting part 21 of the chassis 2 is provided with a second slot 22, and the lower end face 32 of the blade 3 is provided with a second locking block 321, which engages with the second slot 12. When assembling the blade 3, the first locking block 311 of the upper end face 31 of the blade 3 is inserted into the first slot 12 of the first connecting part 11 of the top cover 1, and the second locking block 321 of the lower end face 32 of the blade 3 is inserted into the second slot 22 of the second connecting part 21 of the chassis 2, thereby achieving a fixed connection of the blade 3. The design of the locking structure facilitates the disassembly or installation of the blade 3. Even when rotating at high speed, the blade 3 will not detach from the top cover 1 and the chassis 2. Compared with the traditional welding fixation, the locking structure of this utility model is more practical.

[0025] In this embodiment, the blade 3 is integrally formed with the first locking block 311 and the second locking block 321, which simplifies the manufacturing process of the blade 3 and improves the stamping efficiency of the blade 3.

[0026] In this embodiment, the blade 3 is inclined at 45 degrees. When the blade 3 rotates, an air duct is formed between two adjacent blades 3. The inclined arrangement of the blade 3 can push the air in the air duct, that is, push the air, so that the air flow becomes airflow and generates wind power.

[0027] In this embodiment, five blades 3 are provided between the top cover 1 and the chassis 2. If there are too many blades 3, the air duct between two adjacent blades 3 will be narrowed, reducing the airflow effect and easily causing air duct blockage and reducing air volume. If there are too few blades 3, the kinetic energy generated by the impeller will be reduced, the air duct between two adjacent blades will be widened, and the generated kinetic energy will not be able to push the air in the air duct, resulting in too little air volume.

[0028] In this embodiment, the inner surface 34 of the blade 3 is concave, and the outer surface 35 of the blade 3 is convex. When the blade 3 rotates, the convex outer surface 35 of the blade 3 will accelerate the airflow nearby, forming a low-pressure area. The air outside the impeller is affected by the pressure difference and will flow towards the blade 3. The concave inner surface 34 of the blade 3 converts the mechanical energy of the blade 3 rotation into the kinetic energy of the airflow. The generated kinetic energy compresses and accelerates the air flowing towards the blade 3, turning it into airflow and generating wind power.

[0029] In this embodiment, one end of the blade 3 is provided with a concave arc surface 36, and the other end of the blade 3 is provided with a convex arc surface 37. The design of the concave arc surface 36 reduces the obstruction of the front end of the blade 3 to the airflow and effectively reduces turbulence; the design of the convex arc surface 37 at the rear end of the blade 3 further increases the airflow area on the outer surface 35 of the convex blade 3.

[0030] In this embodiment, the first connecting part 11 of the top cover 1 and the second connecting part 21 of the chassis 2 are both curved. Since the first connecting part 11 of the top cover 1 and the second connecting part 21 of the chassis 2 are both used to connect with the blade 3, when the first connecting part 11 of the top cover 1 and the second connecting part 21 of the chassis 2 are designed as curved, the width of the blade 3 needs to be increased in order to connect and match the curved surface. The increase in the width of the blade 3 increases the air passage area of ​​the outer surface 35 of the blade 3, that is, the air passage area of ​​the outer surface 35 of the blade 3 increases, thus increasing the air volume generated by the impeller.

[0031] In this embodiment, a guide ring 13 is provided on the top of the top cover 1. The function of the guide ring 13 is to make the gas enter the impeller evenly and ensure that the airflow loss is minimized.

[0032] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
