[0013] Preferably, both sides of the sound-insulating long board and the sound-insulating short board are provided with sound-absorbing cotton, and a honeycomb plate is provided on the outside of the sound-absorbing component, which can absorb the noise in the sound-absorbing component.

[0014] Compared with the prior art, this utility model provides a vacuum cleaner with a noise-reducing air duct, which has the following beneficial effects:

[0015] 1. By combining internal sound-absorbing elements, damping springs, sound insulation chambers, and sound-absorbing cotton, the noise generated during motor operation is effectively reduced. Vibration is transmitted from the motor to the inner sound-absorbing layer, then through the damping springs and sound insulation chambers to the sound-absorbing cotton, where it is ultimately absorbed and silenced, reducing the noise level. The damping springs effectively slow down and absorb motor vibration, preventing resonance. Resonance can cause significant noise from structures such as the front hood, which is effectively prevented by the damping design. The outer casing is stably installed inside the front hood through the cooperation of mounting blocks and sliding grooves, preventing loosening or noise generation due to motor vibration during operation. This stable installation method provides reliability for the entire system. The sound-absorbing cotton, as the last line of defense, can comprehensively absorb the noise generated during motor operation, ensuring the entire system is as quiet as possible. The design of the sound-absorbing cotton effectively improves the overall noise reduction effect.

[0016] 2. Through the installation of components such as slots, blocks, sound insulation panels, honeycomb panels, and sound-absorbing cotton, this device can comprehensively reduce noise generated at the fan outlet. Noise is reflected and canceled out by the sound-absorbing components and sound insulation panels of different sizes. At the same time, the sound absorption effect of the sound-absorbing cotton and honeycomb panels ultimately achieves effective noise reduction. This device can effectively reduce the noise level at the air outlet, reduce interference and impact on the surrounding environment and people, and improve the comfort of the working and living environment. The sound-absorbing components are installed using blocks and slots, ensuring their stability and reliability. Through a multi-layered sound-absorbing structure, including sound insulation panels, sound-absorbing cotton, and honeycomb panels, the noise from the fan outlet is effectively eliminated. The sound-absorbing materials of different materials and structures work together to improve the sound absorption effect and ensure effective noise reduction. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides, for example Figure 1-6 A vacuum cleaner with a noise-reducing air duct is shown, including a filter element 7 and a cyclone separator 4 disposed below the filter element 7.

[0026] A dust collection box 2 is provided on the outside of the cyclone 4. A suction pipe 5 is provided on the side of the dust collection box 2. A suction head 6 is provided on the suction pipe 5. A front cover 8 is provided on the side of the filter element 7. A motor 15 is provided inside the front cover 8. A rear cover 9 is provided on the right side of the front cover 8. A base 1 is provided below the front cover 8 and the rear cover 9. An air outlet 12 is provided at the tail of the rear cover 9.

[0027] The inner wall of the front hood 8 is provided with sliding grooves 3 on both sides. The motor 15 is provided with a sound-absorbing inner layer 16 on the outside. Multiple shock-absorbing springs 18 are provided on the outside of the sound-absorbing inner layer 16. Sound-absorbing cotton 17 is provided on the outside of the shock-absorbing springs 18. A sound insulation cavity 19 is provided between the sound-absorbing cotton 17 and the sound-absorbing inner layer 16. An outer shell 14 is provided on the outside of the sound-absorbing cotton 17. Mounting blocks 13 are provided on both sides of the outer shell 14.

[0028] In this embodiment, the working principle of the vacuum cleaner is similar to that of a traditional vacuum cleaner. It mainly uses the motor 15 to drive the cyclone 4 to generate negative pressure to suck in dust and debris, which are then filtered by the filter element 7 and discharged as clean air from the air outlet 12. The specific usage method of this vacuum cleaner is as follows: First, ensure that the vacuum cleaner is charged or has sufficient power. Then, install the appropriate vacuum head 6, extension hose, and other accessories as needed. Next, press the start button or switch to start the vacuum cleaner. Aim the vacuum head 6 at the area to be cleaned, keep the vacuum cleaner stable and move it to ensure that dust and debris are sucked in. Clean the dust box 4, filter element 7, and other components according to the vacuum cleaner model and instructions to maintain the cleaning performance of the vacuum cleaner. Finally, turn off the vacuum cleaner, disconnect the power, tidy up all components, and store the vacuum cleaner properly.

[0029] like Figure 2 , Figure 3 and Figure 4 As shown, the shock-absorbing spring 18 and the sound-absorbing inner layer 16 are welded together. The sound-absorbing inner layer 16 is provided with honeycomb holes. The sound-absorbing inner layer 16 is sleeved on the outside of the motor 15. The sound-absorbing inner layer 16 is fixedly connected to the motor 15. The shock-absorbing spring 18 is fixedly connected to the sound-absorbing cotton 17. The sound-absorbing inner layer 16 and the sound-absorbing cotton 17 form a sound insulation cavity 19, which can isolate sound. The sound-absorbing cotton 17 is fixedly connected to the outer shell 14. The mounting block 13 is integrally connected to the outer shell 14. The outer shell 14 can be engaged with the sliding groove 3 inside the front cover 8 through the mounting blocks 13 on both sides.

[0030] Preferably, through the arrangement of the sound-absorbing inner layer 16, the damping spring 18, the sound insulation cavity 19, the sound-absorbing cotton 17, the outer shell 14, the mounting block 13, and the slide groove 3, the motor 15 is installed inside the sound-absorbing inner layer 16. When the internal motor 15 vibrates during operation, the vibration is transmitted to the sound-absorbing inner layer 16, thereby causing the sound-absorbing inner layer 16 to vibrate. When the vibration of the sound-absorbing inner layer 16 is transmitted to the external damping spring 18, the damping spring 18 can slow down and absorb the vibration of the motor 15, preventing the motor 15 from causing resonance of the front hood 8 and generating large noise. Furthermore, the noise generated when the motor 15 is running is also reduced. The sound will be repeatedly transmitted and canceled inside the sound insulation cavity 19, and finally absorbed by the sound-absorbing cotton 17, further reducing the noise of the motor 15 during operation. The outer shell 14 can be further engaged with the sliding groove 3 inside the front cover 8 by the mounting blocks 13 on both sides. Through the cooperation of the mounting blocks 13 and the sliding groove 3, the outer shell 14 can be stably installed inside the front cover 8. The setting of this device can not only reduce the noise generated by the vibration of the motor 15 causing the front cover 8 to resonate, but also absorb the noise generated by the motor 15 itself during operation through the sound-absorbing cotton 17, ultimately achieving the purpose of silencing the motor 15.

[0031] like Figure 2 , Figure 5 and Figure 6 As shown, the outer side of the air outlet 12 is provided with multiple slots 20, and the inner side of the silencing component 10 is provided with multiple blocks 22. The blocks 22 are fixedly connected to the silencing component 10, and the silencing component 10 can be engaged with the slots 20 through the blocks 22. The silencing component 10 is provided with multiple sound-insulating long plates 21 and sound-insulating short plates 23 inside. The sound-insulating long plates 21 and sound-insulating short plates 23 are arranged alternately. The sound-insulating long plates 21 and sound-insulating short plates 23 are integrated with the silencing component 10. Sound-absorbing cotton 17 is provided on both sides of the sound-insulating long plates 21 and sound-insulating short plates 23. The outer side of the silencing component 10 is provided with a honeycomb plate 11, which can reduce the noise in the silencing component 10.

[0032] Preferably, with the arrangement of the slot 20, the block 22, the sound-insulating long plate 21, the sound-insulating short plate 23, the honeycomb plate 11, and the sound-absorbing cotton 17, the air discharged through the air outlet 12 will also generate a large amount of noise. The sound-absorbing component 10 can be snapped and installed through the block 22 and the slot 20. After the sound-absorbing component 10 is installed, the noise generated by the wind will be continuously reflected and canceled between the sound-insulating long plates 21 and short plates 23 of different sizes when passing through the sound-absorbing component 10. At the same time, the sound-absorbing cotton 17 can absorb the noise. Finally, when the wind is discharged from the honeycomb plate 11, the noise in it will be absorbed again by the honeycomb plate 11. With the arrangement of this device, the noise generated at the air outlet 12 can be effectively reduced, preventing the wind noise at the air outlet 12 from being too large and affecting the surrounding environment.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
