[0026] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0027] In addition, the present application may repeat reference numbers and / or reference letters in different examples, and such repetition is for the purpose of simplicity and clarity, and does not in itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present application provides various specific examples of processes and materials, but those of ordinary skill in the art may recognize the application of other processes and / or the use of other materials.

[0028] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 In a first aspect of the present application, a fan assembly 100 is provided, including: a housing 10 and a fan 20. The housing 10 has an air inlet 101 and an air outlet 102. The fan 20 is disposed in the housing 10 and is connected to the air inlet 101. An air duct 30 connected to the fan 20 and the air outlet 102 is disposed in the housing 10, and the air duct 30 turns at least once.

[0029] Since the shell 10 has an air inlet 101 and an air outlet 102, the fan 20 is arranged in the shell 10 and is connected with the air inlet 101, and the shell 10 is provided with an air duct 30 connected with the fan 20 and the air outlet 102. Therefore, when the fan 20 is working, the gas enters the fan 20 through the air inlet 101, and is discharged through the air duct 30 and the air outlet 102 in sequence. The air duct 30 turns at least once, which can make the gas flow path bend and extend, which helps to attenuate the transmission of sound when the fan 20 is working, and plays a role in noise reduction. At the same time, the inner wall of the air duct 30 can play a role in sound insulation, further play a role in noise reduction, and improve the user experience.

[0030] See also Figure 4 In some embodiments, in order to achieve the bending and extension of the wind flow path, the air duct 30 includes a plurality of sub-air ducts 301, two adjacent sub-air ducts 301 are connected, and the gas flow directions in the two adjacent sub-air ducts 301 are different, and the fan 20 and the air outlet 102 are respectively connected to different sub-air ducts 301. Figure 4 The arrow in the figure indicates the flow direction of the gas from the air inlet 101 to the air outlet 102.

[0031] In some embodiments, when the fan 20 is working, the gas enters the fan 20 through the inlet, and enters one of the multiple sub-ducts 301 through the fan 20. After flowing in the remaining sub-ducts, the gas is discharged through a sub-duct and the air outlet 102. Since the wind flows in two adjacent sub-ducts 301 in different directions, the fan 20 and the air outlet 102 are respectively connected to different sub-ducts 301. Therefore, by allowing the gas to flow in multiple sub-ducts 301, the gas flow path can be bent and extended, which helps to attenuate the transmission of sound when the fan 20 is working, plays a role in noise reduction, and improves the user experience.

[0032] See also Figure 4 In order to achieve noise reduction, the length of the air duct 30 is generally designed to be longer. If it is a long integral air duct arranged in the height direction of the shell 10, it occupies a larger height space of the shell 10. In some embodiments, the air duct can be set to multiple sub-air ducts 301, and the multiple sub-air ducts 301 are arranged along the radial direction of the fan 20, that is, the air duct 30 is divided into multiple sections, and the longest sub-air duct 301 among the multiple sub-air ducts 301 determines the height of the air duct 30, reducing the height of the air duct 30 in the shell 10, that is, reducing the axial size of the air duct 30. Compared with the integral air duct, the length of the air duct can be increased without changing the existing shell.

[0033] See also Figure 4 In some embodiments, multiple sub-ducts 301 are adjacently arranged side by side along the radial direction of the fan 20, so that as many sub-ducts as possible are arranged in the radial direction. Furthermore, the direction of the sub-ducts 301 is perpendicular to the radial direction of the shell 10, so that the distance occupied by each sub-duct 301 in the radial direction can be equal to its own width, which is also the lower limit of the distance occupied by each sub-duct with a fixed width in the radial direction. Therefore, the number of sub-ducts arranged in the radial direction of the shell 10 can be maximized, thereby extending the gas flow path as much as possible and achieving a better noise reduction effect. At the same time, the width of each sub-duct 301 can be reduced as much as possible, which can further increase the number of sub-ducts that can be arranged, so as to maximize the use of the radial space of the shell 10 and reduce configuration requirements.

[0034] According to the foregoing content, by splitting the air duct into multiple sub-air ducts and selecting reasonable air duct size parameters and arrangement methods in the axial and radial directions, the space volume occupied by the air duct is reduced while ensuring the functions of exhaust and noise reduction, thereby achieving optimal utilization of the space inside the shell. In some embodiments, the formation of multiple sub-air ducts 301 can utilize the structure of the shell 10 itself, without adding additional parts, simplifying the installation steps and reducing production costs.

[0035] See also Figure 4 In some embodiments, in order to make the gas flow direction in two adjacent sub-ducts 301 different, the ends of the two adjacent sub-ducts 301 are connected, that is, the sub-duct 301 has an inlet and an outlet, and the two adjacent sub-ducts 301 include a first sub-duct and a second sub-duct, wherein the inlet of the first sub-duct is located at the top of the first sub-duct, the outlet of the first sub-duct is located at the bottom of the first sub-duct, the inlet of the second sub-duct is located at the bottom of the second sub-duct, and the outlet of the second sub-duct is located at the top of the second sub-duct, so as to realize the bending and extension of the gas flow path, which helps to attenuate the transmission of sound when the fan 20 is working, plays a role in noise reduction, and improves the user experience.

[0036] See also Figure 4 In some embodiments, in order to form a plurality of sub-air ducts 301, the fan assembly 100 further includes: a plurality of blocking members 40. The plurality of blocking members 40 are arranged in the housing 10 at intervals and are located between the fan 20 and the air outlet 102. Among them, a sub-air duct 301 is formed between the fan 20 and the adjacent blocking members 40 and between every two adjacent blocking members 40. At the same time, the blocking member 40 can serve as the inner wall of the air duct 30 to play a role in sound insulation, further play a role in noise reduction, and improve the user experience.

[0037] See also Figure 4 In some embodiments, in order to reduce the height of the fan assembly 100, the blocking member 40 is parallel to the rotating shaft of the fan 20, so as to prevent the blocking member 40 from encroaching on the height space of the shell 10, thereby facilitating arrangement and installation. At the same time, the bending and extension of the gas flow path can be completed without increasing the height of the shell 10, without adding additional parts, thereby reducing production costs.

[0038] See also Figure 4 In some embodiments, in order to bend and extend the wind flow path, the flow direction of the gas in two adjacent sub-air ducts 301 is opposite, so that the air duct 30 turns at least once, which helps to attenuate the transmission of sound when the fan 20 is working, plays a role in noise reduction, and improves the user experience.

[0039] See also Figure 4In some embodiments, in order to reduce the height of the fan assembly 100, the air duct 30 is parallel to the rotating shaft of the fan 20, so as to prevent the air duct 30 from encroaching on the height space of the shell 10, which is convenient for layout and installation. At the same time, the bending and extension of the wind flow path can be completed without increasing the height of the shell 10, without adding additional parts, thereby reducing production costs.

[0040] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 In some embodiments, in order to support the fan 20, the housing 10 includes: a fan bracket 103 and a fan housing 104. The air inlet 101 is provided on the fan bracket 103, and the fan 20 is provided on the fan bracket 103. The fan housing 104 is provided to cover the fan 20 and is connected to the fan bracket 103, and the air outlet 102 is provided on the fan housing 104, that is, the fan bracket 103 and the fan housing 104 form an installation space, and the fan 20 can be installed in the installation space to support the fan 20. At the same time, the fan bracket 103 and the fan housing 104 can prevent the fan 20 from being exposed, thereby ensuring the safety of the fan 20 and also ensuring the beauty.

[0041] In some embodiments, in order to facilitate the inspection and disassembly of the fan 20 , the fan bracket 103 is detachably connected to the fan housing 104 .

[0042] See also Figure 4 In some embodiments, in order to reduce costs, the length of the outermost blocking member can be shorter, and the outermost blocking member is in close contact with the fan housing 104, that is, the fan housing 104 can serve as the function of the outermost blocking member, and a sub-air duct 301 can be formed between the blocking member adjacent to the outermost blocking member 40 and the fan housing 104, so that the gas flow path is bent and extended, which helps to attenuate the transmission of sound when the fan 20 is working, thereby playing a role in noise reduction.

[0043] In some embodiments, the blocking member 40 may be disposed on the fan bracket 103 or on the fan housing 104. Of course, in some other embodiments, the blocking member 40 may be disposed on the fan bracket 103 and the fan housing 104.

[0044] In some embodiments, the blocking member 40 is detachably mounted on the fan bracket 103. Of course, in some other embodiments, the blocking member 40 and the fan bracket 103 can be integrally formed.

[0045] In some embodiments, the blocking member 40 is detachably mounted on the fan housing 104. Of course, in some other embodiments, the blocking member 40 can be integrally formed with the fan housing 1043.

[0046] See also Figure 4 In some embodiments, in order to make full use of the space of the shell 10, the projection of the air inlet 101 on the fan housing 104 is staggered with the air outlet 102 along the axial direction of the rotating shaft of the fan 20, so that the gas entering from the air inlet 102 can fully flow in the air duct 30, so that the air duct 30 can be turned at least once, which helps to attenuate the transmission of sound when the fan 20 is working, plays a role in noise reduction, and improves the user experience.

[0047] See also Figure 4 In some embodiments, in order to further reduce noise, the fan assembly 100 further includes: a noise reduction member 50. The noise reduction member 50 is disposed at the air outlet 102. When the gas discharged from the air outlet 102 passes through the noise reduction member 50, the noise is reduced by the noise reduction member 50, which can further reduce noise and improve the user experience. Among them, the noise reduction member 50 can be a noise reduction sponge.

[0048] See also Figure 4 In some embodiments, in order to further reduce noise, the projection of the noise reduction component 50 on the shell 10 at least partially overlaps with the air outlet 102 along the axial direction of the rotating shaft of the fan 20, that is, the noise reduction component 50 can completely block the air outlet 102, so that the wind discharged from the air outlet 102 completely passes through the noise reduction component 50. The noise reduction component 50 can fully reduce noise, thereby improving the user experience.
