Description

Technical Field

[0001] This utility model relates to the field of fan technology, and more specifically, to a quiet and energy-saving fan. Background Technology

[0002] The silent fan is an improved product based on the original GDF duct centrifugal fan box. It maintains the original characteristics of large air volume and low noise, while further reducing the size, noise and energy efficiency. It is suitable for high-end office buildings, high-end hotels, high-end shops and other places that require a quiet environment.

[0003] Based on the above, the inventors have discovered that existing silent fans tend to accumulate a large amount of dust on their internal filter surfaces during use. This dust accumulation clogs the filter pores, hindering airflow and requiring the fan to consume more energy to overcome resistance and maintain normal ventilation. This leads to decreased fan efficiency and increased energy consumption. Furthermore, most existing silent fans rely solely on external enclosures for sound insulation and noise reduction, which is often ineffective. Therefore, in view of this, the inventors have researched and improved the existing structure to provide a silent and energy-saving fan with greater practical value. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0043] Example:

[0044] Please see Figure 1-4 The quiet and energy-saving fan includes a casing 1, inside which the fan body 2 is installed. A soundproof cover 3 is installed on the outer periphery of the casing 1. Sound-absorbing cotton 4 is filled between the inner side of the soundproof cover 3 and the outer periphery of the casing 1. An air outlet 5 and an air inlet 6 are respectively installed at both ends of the soundproof cover 3, and both the air outlet 5 and the air inlet 6 are connected to the interior of the casing 1. An air outlet duct 7 connected to the air outlet 5 is fixedly connected to the end of the casing 1 near the air outlet 5. The fan body 2 is installed to one end of the air outlet duct 7. A filter screen 8 is installed at the end of the casing 1 near the air inlet 6. A dust removal cover 9 is installed at the end of the filter screen 8 near the air outlet 5, and a dust collection box 10 is installed at the end near the air inlet 6. The dust removal cover 9 is connected to the top of the air outlet duct 7 through an air duct assembly 11. One side of the soundproof cover 3 is open, and a soundproof side plate 12 is fixedly connected to the opening by bolts.

[0045] See Figure 1 A check valve 13 is installed at the end of the air outlet 5. There are two air inlets 6, which are arranged in parallel left and right. The size of the two air inlets 6 is 75 mm, and the size of the air outlet 5 is 100 mm.

[0046] See Figure 4 The air intake assembly 11 includes a connector 1101 fixed and connected to the top of the air outlet duct 7, and a sound-absorbing hose 1102 fixed and connected between the top of the connector 1101 and the dust removal hood 9.

[0047] See Figure 3 and Figure 4 An air guide plate 14 is fixedly connected inside the air outlet duct 7 and near the connector 1101. The air guide plate 14 is set at an angle so that part of the air discharged from the fan body 2 can be guided into the dust removal hood 9 to complete the dust removal work of the filter screen 8.

[0048] See Figure 2 The dust removal cover 9 and the dust collection box 10 are both fixedly connected to the ends away from the sound insulation side plate 12 with traction rods 15. One end of each traction rod 15 extends to the outside of the sound insulation cover 3. A traction cylinder 16 is installed on the top of the sound insulation cover 3. The output end of the traction cylinder 16 is fixedly connected to the two traction rods 15 through a connector.

[0049] See Figure 2 Inside the chassis 1, there are two guide rods 17 fixedly connected. The dust cleaning hood 9 and the dust collection box 10 are located between the two guide rods 17 and are slidably connected to the corresponding guide rods 17.

[0050] See Figure 3 Two dust baffles 18 are fixedly connected between the inner walls of both ends of the dust collection box 10, and the two dust baffles 18 are distributed in a figure-eight shape. The dust that is cleaned down can be quickly collected to the bottom of the dust collection box 10 through the dust baffles 18, which facilitates the collection of dust.

[0051] In use: When the fan body 2 is started, air enters through the air inlet 6, is filtered by the filter screen 8, and is discharged through the air outlet 5. The addition of a sound insulation cover 3, sound-absorbing cotton 4, and sound-insulating side panels 12 can block and absorb the noise generated by the operation of the fan body 2, improving the noise reduction effect. When dust appears on the surface of the filter screen 8, part of the air discharged from the fan body 2 is introduced into the dust cleaning cover 9 through the air guide plate 14 on the air outlet duct 7 and with the cooperation of the air guide assembly 11, and blows the dust on the filter screen 8 in reverse, causing the dust on the filter screen 8 to be blown into the dust collection box 10. At the same time, the traction cylinder 16 works, and under the action of the traction rod 15, it drives the dust cleaning cover 9 and the dust collection box 10 to move synchronously, thereby cleaning the dust in various positions of the filter screen 8, effectively preventing the filter screen 8 from becoming clogged during use, greatly improving the efficiency of the fan body 2 and reducing energy consumption.
