Description

Technical Field

[0001] This utility model relates to the field of blower impeller technology, specifically a low-noise high-pressure blower impeller structure. Background Technology

[0002] Centrifugal blowers mainly consist of an inlet casing with an air inlet, a rotary drive unit, a gas compression unit composed of rotating impellers, and an exhaust casing with an exhaust port. The working principle of a centrifugal blower is based on using several rotating impellers to do work on the gas, increasing its kinetic energy. Through centrifugal action and diffusion, the gas pressure is increased to achieve a certain air volume and pressure, thus achieving the technical effect of high-flow-rate, high-pressure air delivery.

[0003] In existing centrifugal blowers, the impeller blades are typically fixed to a mounting base and cannot be disassembled. When air is drawn into the blower, the blades collide with impurities in the air, potentially causing damage over time. Damaged blades necessitate replacing the entire impeller, leading to high maintenance costs. Therefore, a low-noise impeller structure for high-pressure blowers is proposed. Utility Model Content

[0006] As a further preferred embodiment of this technical solution, the blade has an arc-shaped structure, and multiple blades are arranged in a ring array.

[0007] As a further preferred embodiment of this technical solution, the mounting groove is an annular structure, and the axis of the mounting groove is the same as the axis of the mounting base.

[0008] As a further preferred embodiment of this technical solution, the connecting mechanism includes a connecting sleeve, the bottom of the card plate is fixedly connected to the connecting sleeve, the bottom of the mounting groove is provided with a connecting groove that is compatible with the connecting sleeve, and the outer wall of the connecting sleeve and the inner wall of the connecting groove are connected by a threaded fit.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] This utility model provides a technical solution: such as Figures 1 to 4 As shown in this embodiment, a low-noise high-pressure blower impeller structure includes a mounting base 1. Multiple blades 4 are arranged at the upper edge of the mounting base 1. The blades 4 are arc-shaped and arranged in a ring array. A connecting plate 2 is arranged above the blades 4. The connecting plate 2 is a ring-shaped plate structure. An air inlet 3 is located at the center of the connecting plate 2. The bottom of the connecting plate 2 is fixedly connected to the mounting base 1 via multiple connecting rods 14. A disassembly and assembly mechanism is provided between the blades 4 and the mounting base 1. The disassembly and assembly mechanism consists of a clamping plate 5 and a slider 12. The slider 12 is fixedly connected to the bottom of the blades 4 and slidably installed in a groove 13 opened on the upper surface of the mounting base 1. An installation groove 8 is opened on the upper surface of the mounting base 1. The installation groove 8 is a ring structure, and its axis is the same as the axis of the mounting base 1. Multiple grooves 13 are all in communication with the installation groove 8. A clamping plate 5 is provided in the installation groove 8 and is fixedly connected to the installation groove 8 via a connecting mechanism.

[0021] The connecting mechanism includes a connecting sleeve 7. The bottom of the clamping plate 5 is fixedly connected to the connecting sleeve 7. The bottom of the mounting groove 8 is provided with a connecting groove 9 that is compatible with the connecting sleeve 7. The outer wall of the connecting sleeve 7 and the inner wall of the connecting groove 9 are connected by a threaded fit.

[0022] The threaded connection between the connecting sleeve 7 and the connecting groove 9 allows for easy assembly and disassembly of the card plate 5.

[0023] The upper end of the card plate 5 has a groove 6.

[0024] The groove 6 allows the user to easily rotate the card plate 5.

[0025] The outer diameter of the card plate 5 is smaller than the inner diameter of the air inlet 3.

[0026] With this setup, the card plate 5 can be removed from the air inlet 3.

[0027] The lengths of blade 4 and slider 12 are both less than the distance between the two inner walls of the mounting groove 8.

[0028] With this configuration, when disassembling blade 4, slider 12 can be moved from slide groove 13 to mounting groove 8.

[0029] The mounting base 1 has a connection hole 10 at its center, and a keyway 11 is provided on the inner wall of the connection hole 10.

[0030] The mounting base 1 can be connected to the output shaft of the motor through the connection hole 10, and can be adapted to the key on the motor output shaft through the keyway 11, thereby preventing the mounting base 1 from rotating relative to the motor output shaft.

[0031] This utility model provides a low-noise high-pressure blower impeller structure, the specific working principle of which is as follows:

[0032] When the impeller blade 4 is damaged, press the groove 6 with your hand and rotate the clamping plate 5 counterclockwise. This will cause the connecting sleeve 7 at the bottom of the clamping plate 5 to fall out of the connecting groove 9. Remove the clamping plate 5 from the air inlet 3. Then, move the damaged blade 4 towards the axis of the mounting base 1, so that the slider 12 at the bottom of the blade 4 moves from the slide groove 13 into the mounting groove 8. At this point, the blade 4 can be removed from the air inlet 3, thus completing the disassembly of the damaged blade 4. Next, reinstall the new blade 4 onto the mounting base 1. Finally, rotate the connecting sleeve 7 into the connecting groove 9, so that the outer wall of the clamping plate 5 abuts against the slider 12 in the slide groove 13, thus completing the installation of the new blade 4. This eliminates the need to replace the entire impeller, effectively reducing the impeller's maintenance costs. At the same time, because the blade 4 is easy to disassemble and assemble, it is also convenient to clean the outer surface of the blade 4 during daily use, preventing the blade 4 from rusting due to lack of cleaning over a long period of time, which would lead to increased noise when the blade 4 is blowing air, thereby reducing the noise of the blower.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
