[0022] Air inlet, the air inlet being used to introduce an airflow source;

[0023] An air outlet structure, wherein the air outlet structure is the air outlet structure of any embodiment of the first aspect described above;

[0024] An air outlet duct is used to connect the air outlet structure and the air inlet.

[0025] Optionally, the air outlet channel includes at least two, and each air outlet channel is provided with the air outlet structure.

[0026] Optionally, it also includes a flow guide block.

[0031] The thickness of the end of the guide block away from the air inlet protruding from the inner wall of the air outlet channel where the air outlet structure is located is greater than the distance the guide portion extends out of the inner wall of the air outlet channel.

[0032] A third aspect of this utility model provides a fan device, comprising:

[0033] Air inlet, the air inlet being used to introduce an airflow source;

[0034] An air outlet structure, wherein the air outlet structure is the air outlet structure of any embodiment of the first aspect described above;

[0035] An air outlet duct is used to connect the air outlet structure and the air inlet.

[0036] Optionally, it also includes:

[0037] case,

[0038] The housing is annular, and the air outlet channel is formed inside the housing.

[0039] The air inlet is formed at one end of the housing.

[0049] This utility model's air outlet structure includes a main air outlet channel arranged in parallel and at least one secondary air outlet channel adjacent to the main air outlet channel. During air delivery, the central main air outlet channel serves as the main airflow output port, while the secondary air outlet channels on either side of the main air outlet channel serve as auxiliary airflow output ports. The main air outlet channel blows out the main airflow, and the secondary air outlet channels on the sides blow out the auxiliary airflow. This achieves the purpose of air delivery (i.e., conveying the main airflow) by having the auxiliary airflow on the sides cover the surface of the main airflow in contact with the air. The auxiliary airflow on both sides covering the surface of the main airflow in contact with the air reduces friction between the surface of the main airflow and the air, thereby reducing airflow loss and increasing the airflow volume. This allows for a longer air delivery distance with a fixed main airflow rate. Furthermore, by reducing the friction between the surface of the main airflow and the air, a lower speed is required for the drive motor to achieve the same air delivery distance, thus reducing the overall power consumption of the unit.

[0066] In the description of this embodiment, it should be understood that the terms "length", "width", "height", "up", "down", "left", "right", "vertical", "horizontal", "bottom", "inner", "outer", "front", "back", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0067] As a specific embodiment of this utility model, such as Figure 1 , Figure 2As shown, the air outlet structure includes a main air outlet channel arranged in parallel and secondary air outlet channels on both sides of the main air outlet channel. The main air outlet channel and the secondary air outlet channels are spaced apart, and the thickness of the spacer wall is less than or equal to 30mm. Air delivery (i.e., conveying the main airflow) is achieved by having the secondary airflow on the sides cover the surface of the main airflow in contact with the air. This lateral secondary airflow covering the surface of the main airflow in contact with the air reduces friction between the surface of the main airflow and the air, thereby reducing airflow loss and increasing the air volume. This allows for a longer air delivery distance with a fixed main airflow rate.

[0068] The air outlet structure of the first aspect embodiment of this utility model may include a main air outlet channel 400 and at least one secondary air outlet channel 500 arranged in parallel. The secondary air outlet channel 500 is adjacent to the main air outlet channel 500. The cross-sectional area of ​​the inner air outlet of the secondary air outlet channel 500 is smaller than that of the inner air outlet of the main air outlet channel 400, and the cross-sectional area of ​​the outer air outlet of the secondary air outlet channel 500 is larger than that of the inner air outlet of the secondary air outlet channel 500. It should be noted that the cross-sectional area of ​​the main air outlet channel can remain constant along the air outlet direction.

[0069] Specifically, the air outlet structure of this utility model includes a main air outlet channel 400 arranged in parallel and at least one secondary air outlet channel 500. The secondary air outlet channel 500 is adjacent to the main air outlet channel 500. When this air outlet structure delivers air, the central main air outlet channel 400 serves as the main airflow output port, while the adjacent secondary air outlet channel 500 serves as the secondary airflow output port. The main air outlet channel 400 blows out the main airflow, and the secondary air outlet channel 500 blows out the secondary airflow. This secondary airflow covers the surface of the main airflow in contact with the air, thus achieving the purpose of air delivery (i.e., conveying the main airflow). The secondary airflow covering the surface of the main airflow in contact with the air reduces friction between the surface of the main airflow and the air, thereby reducing airflow loss and increasing the airflow volume. This allows for a longer air delivery distance with a fixed main airflow flow rate. Simultaneously, the secondary airflow configuration makes the main airflow more concentrated, further ensuring the direction and speed of the main airflow. Furthermore, by reducing the friction between the surface of the main airflow and the air, the drive motor requires a lower speed to achieve the same air delivery distance, thus reducing the overall power consumption of the machine.

[0070] As an example, the air outlet structure of this utility model can have one or more secondary air outlet channels 500 provided on one side of the main air outlet channel 400, or one or more secondary air outlet channels 500 provided on each side of the main air outlet channel 400. For example, one secondary air outlet channel 500 can be provided on one side of the main air outlet channel 400; at least two secondary air outlet channels 500 can be provided on one side of the main air outlet channel 400; or at least one secondary air outlet channel 500 can be provided on each side of the main air outlet channel 400. It is understood that the number of secondary air outlet channels 500 provided on both sides of the main air outlet channel 400 can be the same or different, and is not limited here. Furthermore, there can be one main air outlet channel 400, or multiple channels arranged side-by-side with intervals. The specific arrangement can be selected according to the actual application, and this application does not impose specific limitations here.

[0071] As one embodiment of this utility model, when there are at least two secondary air vent channels 500, each secondary air vent channel 500 is arranged in parallel.

[0072] Specifically, when at least two secondary air outlet channels 500 are provided, the two or more secondary air outlet channels 500 can be arranged side by side, that is, the two or more secondary air outlet channels 500 are arranged side by side and aligned in the same direction. For example, the two or more secondary air outlet channels 500 can be arranged on one side of the main air outlet channel 400, or the two or more secondary air outlet channels 500 can be arranged on both sides of the main air outlet channel 400. When the two or more secondary air outlet channels 500 are arranged side by side and aligned in the same direction, the surface air pressure corresponding to the main airflow can be stabilized when the secondary airflow is output simultaneously, thereby reducing the flow loss of the main airflow.

[0073] It should be noted that the main air outlet channel 400 and the secondary air outlet channel 500 have the same diameter along the first direction (e.g., the thickness direction of the channel) and are aligned with each other. This further ensures that the main airflow is fully covered by the secondary airflow and that the pressure on each surface is balanced, thus ensuring uniform output.

[0074] Understandably, in other embodiments, multiple secondary air outlet channels may not be arranged side-by-side; for example, they may be arranged vertically or in other ways, which are not limited here. It should be noted that the inner air outlet size (i.e., cross-sectional area) of the main air outlet channel 400 is larger than the inner air outlet size of the secondary air outlet channel 500, so that the air volume of the secondary airflow blown out by the secondary air outlet channel 500 is less than the air volume of the main airflow blown out by the main air outlet channel 400, ensuring that most of the air volume flows out by the main airflow, thereby ensuring the air outlet effect. Moreover, the outer air outlet size of the secondary air outlet channel 500 is larger than the inner air outlet size of the secondary air outlet channel 500, so that the flow velocity of the secondary airflow blown out by the secondary air outlet channel 500 is not greater than the flow velocity of the main airflow blown out by the main air outlet channel 400, thereby preventing the main airflow from diverging due to the excessively fast flow velocity of the secondary airflow, which would have a negative effect on the air outlet effect of the main air outlet. Therefore, the above method can ensure the coverage and protection effect of the secondary airflow on the surface of the main airflow, reduce the loss of the main airflow volume, and optimize the air outlet effect of the air outlet structure.

[0075] As an example, such as Figure 3 As shown in the figure, the arrows indicate the direction of airflow through the main air vent channel 400 and the secondary air vent channel 500. S1, S2, and S3 represent the cross-sectional areas of the inner and outer air vents of the secondary air vent channel 500 and the inner air vent of the main air vent channel 400, respectively. That is, S1 is less than S2 and S3 is less than S3.

[0076] Preferably, the cross-sectional area of ​​the secondary air outlet channel 500 gradually increases along the air outlet direction.

[0077] In other words, in this embodiment, the diameter of the secondary air inlet channel 500 gradually increases along the direction from the inner air inlet to the outer air inlet, thereby making the size of the outer air inlet of the secondary air inlet channel 500 larger than the size of the inner air inlet. On the one hand, the method of narrowing first and then widening (i.e., the size of the outer air inlet is larger than the size of the inner air inlet) can improve the problem of excessively high air velocity caused by airflow passing through a smaller air inlet, reducing the air velocity while ensuring a small airflow volume, and preventing the main airflow from diverging due to excessively high secondary airflow velocity; on the other hand, the gradual diameter design can further achieve uniformity and stability of airflow delivery.

[0078] As a specific embodiment of this utility model, such as Figure 1 , Figure 2 As shown, a partition wall 600 is provided between the main air outlet channel 400 and the secondary air outlet channel 500, and the thickness of the partition wall 600 is less than or equal to 30 mm. It should be noted that the thickness of the partition wall 600 is the distance between the adjacent sides of the main air outlet channel 400 and the secondary air outlet channel 500.

[0079] Specifically, in this embodiment, the main air outlet channel 400 and the secondary air outlet channel 500 are spaced apart, with a partition wall 600 between them. This ensures that the main airflow from the main air outlet channel 400 is completely covered by the secondary airflow from the secondary air outlet channel 500, without interference, thus guaranteeing the stability of the main airflow output and reducing losses. Preferably, the thickness of the partition wall 600 is less than or equal to 30 mm.

[0080] Furthermore, in order to further ensure the adhesion between the main airflow and the secondary airflow and optimize the protective effect of the secondary airflow on the main airflow, the thickness of the partition wall 600 can be set to less than or equal to 10mm.

[0081] As a specific embodiment of this utility model, such as Figure 2 As shown, a main air inlet channel 400 and two secondary air inlet channels 500 on each side can be set. By setting secondary airflow channels on both sides of the main airflow, the protection of the main airflow can be more comprehensive, further reducing the loss of the main airflow. As a specific embodiment of this utility model, as... Figure 2 As shown, the air outlet structure may also include at least one partition 800, which is used to separate the main air outlet channel 400 and the secondary air outlet channel 500 to divide the main air outlet channel 400 and the secondary air outlet channel 500 into at least two air outlet units 600.

[0082] Specifically, one or more baffles 600 can be arranged along the extension direction of the main air outlet channel 400 and the secondary air outlet channel 500. The baffles 600 divide the main air outlet channel 400 and the secondary air outlet channel 500 into two or more air outlet units 600 along the extension direction, thus creating multiple air outlet units 600 for airflow, resulting in more stable, uniform, and controllable airflow. For example, by adjusting the number of air outlet units 600 formed by the baffles, different numbers correspond to different areas of the air outlet units, thereby controlling the specific airflow effect. A larger number of units results in a smaller air outlet area, producing a finer and smoother airflow; conversely, fewer units have the opposite effect.

[0083] Preferably, the partition 800 is arranged along the air outlet direction of the main air outlet channel 400 and the secondary air outlet channel 500.

[0084] In other words, by setting the baffle 800 parallel to the through direction of the main air outlet channel 400 and the secondary air outlet channel 500, we can minimize the interference between the baffle 800 and the passing airflow, reducing airflow loss. Furthermore, the baffle can act as a guide structure, directing the airflow to the corresponding air outlet unit, thus making the airflow direction from each air outlet unit more uniform. For example, it could be parallel to the upper and lower sides of the inner walls of the main air outlet channel 400 and the secondary air outlet channel 500, thereby making the extension direction of the formed air outlet unit parallel to the airflow direction, resulting in a more uniform airflow direction, while reducing airflow loss due to the baffle and ensuring airflow volume.

[0085] As a specific embodiment of this utility model, such as Figure 2 As shown, each air outlet unit includes a main air outlet unit 410 arranged in parallel and at least one secondary air outlet unit 510 adjacent to the main air outlet unit 410.

[0086] Specifically, the main air vent 400 and the secondary air vent 500 are connected along the extension direction (i.e., by means of the partition 800) Figure 2 The air outlet (pointing to the middle arrow) is divided into multiple outlet units 600 formed by the main air outlet unit 410 and its adjacent secondary air outlet unit 510 arranged side by side, thereby making the airflow delivered by the main air outlet channel 400 and the secondary air outlet channel 500 more uniform, thus further improving the quality of air delivery.

[0087] It should be noted that the air outlet unit may include a main air outlet unit 410 and one or more secondary air outlet units 510 arranged on one side of the main air outlet unit 410, or it may include a main air outlet unit 410 and one or more secondary air outlet units 510 arranged on both sides of the main air outlet unit 410. The air outlet unit may also include two or more parallel main air outlet units 410 and one or more secondary air outlet units 510 arranged on one or both sides of the two or more main air outlet units 410.

[0088] As a specific embodiment of this utility model, at least two air outlet units are arranged sequentially along the direction away from the airflow source.

[0089] Specifically, at least two air outlet units (including a main air outlet unit 410 and a secondary air outlet unit 510 arranged side by side) are arranged sequentially in a direction away from the airflow source (e.g., an air inlet). Thus, when the airflow source flows towards the air outlet units, the airflow can be evenly distributed through the sequentially arranged air outlet units. For example, as... Figure 5 As shown in the figure, the arrows indicate the location of the airflow source. The airflow source flows out in the direction from bottom to top (in the direction of the arrows). At least two air outlet units are arranged in the direction from bottom to top so that the airflow can enter each air outlet unit evenly.

[0090] As a specific embodiment of this utility model, the partition 800 includes at least two, and the distance between two adjacent partitions 800 gradually increases along the direction away from the airflow source.

[0091] Specifically, such as Figure 6 As shown, baffles 800 are arranged in a bottom-to-top direction (i.e., the direction of airflow from the air source). Because the airflow rate is higher near the air source and lower further away, the spacing between adjacent baffles 800 gradually increases in the direction away from the air source (as an example). Figure 6 (where d1 is greater than d2), thus it can better gather a sufficient amount of airflow to the air outlet unit that is far from the airflow source, ensuring the uniformity of airflow delivery.

[0092] As a specific embodiment of this utility model, such as Figure 6 As shown, a guide portion 810 extending toward the airflow source is formed on the partition 800.

[0093] Specifically, each partition 800 has a guide portion 810 extending toward the airflow source (e.g., into the interior of the air outlet channel), thereby forming an air outlet guide area 820 between adjacent guide portions 810. Each air outlet guide area 820 corresponds to an air outlet unit. The airflow in the air outlet channel is uniformly introduced to the corresponding air outlet unit through the air outlet guide area 820, thereby further ensuring the uniformity of airflow delivered from multiple air outlet units in the main air outlet channel 400 and the secondary air outlet channel 500.

[0094] As a specific embodiment of this utility model, such as Figure 7 As shown, the end of the guide section 810 bends toward the airflow source.

[0095] Specifically, the end of the guide section 810, that is, the end opposite to the partition 800, points downwards (towards the airflow source). Figure 7 The middle arrow indicates the direction of airflow (curve).

[0096] This allows the outflowing air from the air source to be efficiently introduced into the air outlet guide zone 820, thus improving the guiding effect.

[0097] As a specific embodiment of this utility model, the portion of the guide part 810 near the partition 800 is connected in parallel with the partition 800.

[0098] Specifically, the guide section 810 is located near the part of the partition 800 that is connected to it (i.e. Figure 7 The left side of the guide section 810 is straight and is parallel to the partition plate 800 to form a flat surface, thereby ensuring the structural strength of the part of the guide section 810 near the partition plate 800.

[0099] As a specific embodiment of this utility model, such as Figure 7 As shown, the partition 710 has at least two guide sections 810, the first preset number of which are farther from the airflow source are longer than the second preset number of which are closer to the airflow source. The first and second preset numbers can be set according to actual conditions. Figure 7 The following example illustrates this point: the five guide sections furthest from the airflow source are longer than the 20 guide sections 810 closest to the airflow source.

[0100] Specifically, since airflow away from the airflow source tends to converge on the other side of the air outlet unit, a better airflow guiding effect can be achieved by lengthening the guide portion 810 away from the airflow source.

[0101] Furthermore, simulation evaluations were conducted on the single air outlet in existing technologies and the air outlet structure of this application. For example... Figure 6 and Figure 7 As shown, under the same conveying distance, the end of the single airflow 10 delivered from a single outlet ( Figure 6 The opening at the middle of the left end shows a clear tendency to narrow. The air outlet of this application is located at the end of the main airflow 20, which is enveloped by the secondary airflows 30 on both sides. Figure 7 The opening in the middle of the left end shows a relatively slow closing trend.

[0102] in addition, Figure 10 and Figure 11 The diagrams show a single airflow 10 injection simulation and a simulation of two secondary airflows 30 enveloping the main airflow 20. In comparison, the air outlet structure of this application, through the delivery method of the secondary airflows 30 enveloping the main airflow 20, can achieve a larger air volume over the same distance.

[0103] In addition, the size of multiple air outlets can be adjusted through simulation to ensure that the air volume, air speed and air delivery distance meet the requirements while achieving the purpose of noise reduction.

[0104] A second aspect of this utility model provides an air outlet device, such as... Figure 4 and Figure 5 As shown, it may include:

[0105] Air inlet 200, used to introduce airflow source;

[0106] The air outlet structure is the air outlet structure of any embodiment of the first aspect described above;

[0107] An air outlet duct 300 is used to connect the air outlet structure and the air inlet 200. As a specific embodiment of this utility model, there are at least two air outlet ducts 300, and each air outlet duct 300 is provided with an air outlet structure.

[0108] Specifically, Figure 4 The illustration only uses two air outlet channels. In this embodiment, more than two air outlet channels 300 can be provided, and air outlet structures can be provided on the corresponding air outlet channels 300 to achieve air supply. The specific configuration can be set according to actual needs, and this application does not limit it here.

[0109] As a specific embodiment of this utility model, such as Figure 5 As shown, the air outlet device may also include a guide block 900. The guide block 900 abuts against the inner wall of the air outlet duct 300 where the air outlet structure is located near the air inlet 200, and the guide block 900 is used to guide the airflow to the air outlet structure.

[0110] In other words, in order to improve the quality and efficiency of airflow delivery, a guide block 900 can be installed in the air outlet channel 300 near the air inlet 200. The guide block 900 can be matched to the shape of the corresponding air outlet structure and the air outlet channel 300 to ensure that the quality and efficiency of airflow delivered from the air inlet 200 to the air outlet structure are maximized.

[0111] As a specific embodiment of this utility model, such as Figure 5 As shown, the thickness of the guide block 900 within the air outlet 300 gradually increases in the direction away from the air inlet 200.

[0112] Specifically, on the one hand, the guide block 900 can reduce the space occupied inside the air outlet 300 near the air inlet 200, thereby ensuring the air intake volume of the air inlet 200; on the other hand, the guide block 900 can compress the space inside the air outlet 300 away from the air inlet 200, thereby increasing the air pressure and flow velocity of the airflow inside the air outlet 300 towards the multiple air outlet guide areas 620, thus ensuring that the distant air outlet guide areas 620 can also be allocated sufficient airflow.

[0113] As a specific embodiment of this utility model, such as Figure 5 As shown, the air outlet structure also includes at least one baffle 800, on which a guide portion 810 is formed extending toward the inner wall of the air outlet channel 300. The thickness of the protrusion of the end of the guide block 900 away from the air inlet 200 relative to the inner wall of the air outlet channel 300 of the air outlet structure is greater than the distance of the guide portion 810 extending out of the inner wall of the air outlet channel 300.
