[0019] Optionally, the partition has at least two guide portions, and a first preset number of guide portions away from the airflow source has a longer length than a second preset number of guide portions close to the airflow source.

[0020] A second aspect of the present invention provides an air outlet device, comprising:

[0021] An air inlet, the air inlet is used to allow an air flow source to enter;

[0022] An air outlet, wherein the air outlet is the air outlet of any embodiment of the first aspect above;

[0023] An air outlet channel is used to connect the air outlet and the air inlet.

[0024] Optionally, the air outlet channels include at least two, and each of the air outlet channels is provided with the air outlet.

[0025] Optionally, a guide block is also included.

[0026] The guide block is close to the air inlet and abuts against the inner side wall of the air outlet channel where the air outlet is located, and the guide block is used to guide the airflow to the air outlet.

[0027] Optionally, the thickness of the guide block in the air outlet channel gradually increases in a direction away from the air inlet.

[0028] Optionally, the air outlet further includes at least one partition.

[0029] The partition plate is formed with a guide portion extending toward the inner side wall of the air outlet passage.

[0031] A third aspect embodiment of the present invention provides a fan, comprising:

[0032] An air inlet for introducing an air flow source;

[0033] An air outlet, which is the air outlet of any one of the embodiments in the first aspect above;

In addition, when the friction between the surface of the main airflow and the air is reduced, when the same air supply distance is achieved, the speed required for the drive motor is lower, which can reduce the power consumption of the whole machine.

[0061] In the description of this embodiment, it should be understood that the terms "length", "width", "height", "up", "down", "left", "right", "vertical", "horizontal", "bottom", "inside", "outside", "front", "back", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0062] As a specific embodiment of the present invention, Figure 1 , Figure 2 As shown, the air outlet of the air outlet device of the first aspect of the present invention may include a main air outlet channel 400 and at least one secondary air outlet channel 500 arranged in parallel. The main air outlet channel 400 and the secondary air outlet channel 500 are adjacent. The cross-sectional area of ​​the inner air outlet of the secondary air outlet channel 500 is smaller than the cross-sectional area 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 the cross-sectional area of ​​the inner air outlet of the secondary air outlet channel 500.

[0063] Specifically, the air outlet of the air outlet device of the present invention includes a main air outlet channel 400 arranged in parallel, and at least one secondary air outlet channel 500 adjacent to the main air outlet channel 500. When the air outlet is delivering air, the middle main air outlet channel 400 serves as the main airflow output port, and the secondary air outlet channel 500 adjacent to the main air outlet channel 400 serves as the secondary airflow output port. The main air outlet channel 400 blows out the main airflow, and the side secondary air outlet channel 500 blows out the secondary airflow, so that the purpose of delivering air (i.e., conveying the main airflow) is achieved by covering the surface where the middle main airflow contacts the air with the side secondary airflow. Among them, the side secondary airflow covers the surface where the main airflow contacts the air, which can reduce the friction between the surface of the main airflow and the air, reduce the airflow loss, and play the effect of increasing the air output. At the same time, it can make it possible to achieve a longer air delivery distance when the main airflow flow is fixed. At the same time, the main airflow can be more concentrated by setting the secondary airflow, and the wind direction and wind speed of the main airflow can be further guaranteed. In addition, when the friction between the surface of the main airflow and the air is reduced, the speed required for the drive motor is lower when the same air supply distance is achieved, thereby reducing the power consumption of the entire machine.

[0064] As an example, the air outlet of the air outlet device of the present invention may be provided with one or more secondary air outlet channels 500 on one side of the main air outlet channel 400, or one or more secondary air outlet channels 500 may be provided on both sides of the main air outlet channel 400. For example, one secondary air outlet channel 500 is provided on one side of the main air outlet channel 400; at least two secondary air outlet channels 500 are provided on one side of the main air outlet channel 400; at least one secondary air outlet channel 500 is provided on both sides of the main air outlet channel 400. It can be understood that the number of secondary air outlet channels 500 provided on both sides of the main air outlet channel 400 may be the same or different, and is not limited here. In addition, the main air outlet channel 400 may be one or multiple main air outlet channels 400 may be provided in parallel and spaced apart. The specific setting may be selected according to the actual application, and this application does not make specific limitations here.

[0065] As an embodiment of the present invention, when there are at least two secondary air outlet channels 500, the secondary air outlet channels 500 are arranged in parallel.

[0066] Specifically, when at least two secondary air outlet channels 500 are provided, the two or more secondary air outlet channels 500 may be provided in parallel, that is, the two or more secondary air outlet channels 500 are provided in parallel and aligned in the same direction. For example, the two or more secondary air outlet channels 500 are provided on one side of the main air outlet channel 400, or the two or more secondary air outlet channels 500 are provided on both sides of the main air outlet channel 400, respectively. When the two or more secondary air outlet channels 500 are provided in parallel and aligned in the same direction, the surface 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.

[0067] It can be understood that in other embodiments, multiple secondary air outlet channels may not be arranged in parallel, 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., the 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 air flow blown out by the secondary air outlet channel 500 is smaller than the air volume of the main air flow blown out by the main air outlet channel 400, ensuring that most of the air volume flows out of the main air flow, thereby ensuring the air outlet effect; and, the size of the outer air outlet of the secondary air outlet channel 500 is larger than the size of the inner air outlet of the secondary air outlet channel 500, so that the flow rate of the secondary air flow blown out by the secondary air outlet channel 500 is not greater than the flow rate of the main air flow blown out by the main air outlet channel 400, thereby preventing the main air flow from diverging due to the excessive flow rate of the secondary air flow, which in turn causes 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 air flow on the surface of the main air flow, reduce the loss of the air volume of the main air flow, and optimize the air outlet effect of the air outlet.

[0068] As an example, Figure 3 As shown, the direction of the arrow in the figure is the direction of the airflow through the main air outlet channel 400 and the secondary air outlet channel 500, wherein s1, s2 and s3 represent the cross-sectional areas of the inner air outlet, the outer air outlet of the secondary air outlet channel 500 and the inner air outlet of the main air outlet channel 400, respectively, that is, s1 is smaller than s2, and s1 is smaller than s3.

[0069] Preferably, the cross-sectional area of ​​the secondary air outlet channel 500 gradually increases along the air outlet direction.

[0070] That is to say, the aperture size of the secondary air outlet channel 500 of this embodiment gradually increases along the direction from the inner air outlet to the outer air outlet, so that the size of the outer air outlet of the secondary air outlet channel 500 is larger than the size of the inner air outlet of the secondary air outlet channel 500. On the one hand, the method of narrowing first and then widening (i.e., the size of the outer air outlet is larger than the size of the inner air outlet) can improve the problem of too high wind speed caused by airflow passing through a smaller air inlet, and reduce the wind speed while ensuring a small amount of air intake, so as to prevent the main airflow from diverging due to the excessive speed of the secondary airflow; on the other hand, the uniformity and stability of airflow delivery can be further achieved through the gradual aperture design.

[0071] As a specific embodiment of the present invention, Figure 1 , Figure 2 As shown, a partition wall 600 is provided between the primary 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 primary air outlet channel 400 and the secondary air outlet channel 500.

[0072] Specifically, the main air outlet channel 400 and the secondary air outlet channel 500 of this embodiment are arranged at intervals, and a partition wall 600 is formed between them so that the main air outlet channel 400 and the secondary air outlet channel 500 are independent of each other and not connected, and finally the surface of the main airflow sent out by the main air outlet channel 400 is just covered by the secondary airflow sent out by the secondary air outlet channel 500, and they do not interfere with each other, thereby ensuring the stability of the main airflow output and reducing losses. Preferably, the thickness of the partition wall 600 is set to be less than or equal to 30 mm.

[0073] Furthermore, in order to further ensure the adhesion between the primary airflow and the secondary airflow and optimize the protective effect of the secondary airflow on the primary airflow, the thickness of the partition wall 600 can be set to be less than or equal to 10 mm.

[0074] As a specific embodiment of the present invention, Figure 2 As shown, a main air outlet channel 400 and two secondary air outlet channels 500 on both sides can be provided. By providing secondary airflows on both sides of the main airflow, the main airflow can be more fully protected and the loss of the main airflow can be further reduced. As a specific embodiment of the present invention, Figure 2 As shown, the air outlet of the air outlet device may further include at least one partition 800 , which is used to separate the main air outlet channel 400 and the secondary air outlet channel 500 , so as to divide the main air outlet channel 400 and the secondary air outlet channel 500 into at least two air outlet units 600 .

[0075] Specifically, one or more partitions 600 can be arranged in the extension direction of the main air outlet channel 400 and the secondary air outlet channel 500. The partitions 600 divide the main air outlet channel 400 and the secondary air outlet channel 500 into more than two air outlet units 600 in the extension direction, thereby dividing them into multiple air outlet units 600 for air discharge, and the air discharge is more stable, uniform and controllable. For example, by adjusting the number of air outlet units 600 formed by the partition, different numbers correspond to different areas of air outlet units, thereby controlling the specific air outlet effect setting. The more the number, the smaller the air outlet area of ​​the air outlet unit, and the more fine and smooth the wind blown out; otherwise, the effect is the opposite.

[0076] Preferably, the partition plate 800 is arranged along the air outlet direction of the main air outlet channel 400 and the secondary air outlet channel 500 .

[0077] That is to say, by setting the partition 800 parallel to the penetration direction of the main air outlet channel 400 and the secondary air outlet channel 500, on the one hand, the partition 800 can minimize the interference with the passing airflow and reduce the loss of airflow flow; on the other hand, the partition can serve as a guide structure to guide the airflow to the corresponding air outlet unit, so that the airflow direction blown out by each air outlet unit is more uniform. For example, it can be parallel to the upper and lower side surfaces of the inner side walls of the main air outlet channel 400 and the secondary air outlet channel 500, so that the extension direction of the formed air outlet unit is parallel to the air outlet direction, so that the direction of the blown airflow is more uniform, while reducing the loss of the airflow caused by the partition and ensuring the airflow flow.

[0078] As a specific embodiment of the present invention, 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 .

[0079] Specifically, the main air outlet channel 400 and the secondary air outlet channel 500 are separated along the extension direction (i.e. Figure 2 The main air outlet channel 400 and the secondary air outlet channel 500 are divided into a plurality of air outlet units 600 (in the direction of the middle arrow) which are formed by a main air outlet unit 410 and its adjacent secondary air outlet units 510 arranged in parallel at intervals, thereby making the airflow delivered by the main air outlet channel 400 and the secondary air outlet channel 500 more uniform, thereby further improving the quality of air supply.

[0080] 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 disposed on one side of the main air outlet unit 410, or may include a main air outlet unit 410 and one or more secondary air outlet units 510 disposed 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 disposed on one side or both sides of the two or more main air outlet units 410.

[0081] As a specific embodiment of the present invention, at least two air outlet units are arranged in sequence along a direction away from an air flow source.

[0082] Specifically, at least two air outlet units (including a primary air outlet unit 410 and a secondary air outlet unit 510 arranged in parallel) are arranged in sequence in a direction away from an air flow source (for example, an air inlet), so that when the air flow source flows toward the air outlet unit, the air flow can be evenly delivered through the sequentially arranged air outlet units. Figure 5 As shown, the arrow in the figure marks the position of the air flow source, the air flow source flows out along the bottom-up direction (the direction of the arrow), and at least two air outlet units are arranged along the bottom-up direction so that the air flow can enter each air outlet unit evenly.

[0083] As a specific embodiment of the present invention, the partition plates 800 include at least two, and the distance between two adjacent partition plates 800 gradually increases in the direction away from the airflow source.

[0084] Specifically, Figure 6 As shown, the partitions 800 are arranged along the direction from bottom to top (i.e., the flow direction of the airflow source). Since the airflow volume near the airflow source is larger and the airflow volume far from the airflow source is smaller, the spacing between adjacent partitions 800 gradually increases along the direction away from the airflow source (as an example, Figure 6 In the example, d1 is greater than d2), so that a sufficient amount of airflow can be better gathered to the air outlet unit that is farther away from the airflow source, thereby ensuring the uniformity of airflow delivery.

[0085] As a specific embodiment of the present invention, Figure 6 As shown, a guide portion 810 extending toward an air flow source is formed on the partition 800 .

[0086] Specifically, each partition 800 is formed with a guide portion 810 extending toward the air flow source (for example, it may be extended into the interior of the air outlet channel), so that an air outlet guide area 820 is formed between adjacent guide portions 810, and each air outlet guide area 820 corresponds to an air outlet unit. The air flow in the air outlet channel is uniformly introduced into the corresponding air outlet unit through the air outlet guide area 820, thereby further ensuring the uniformity of the air flow delivered from multiple air outlet units in the main air outlet channel 400 and the secondary air outlet channel 500.

[0087] As a specific embodiment of the present invention, Figure 7 As shown, the distal end of the guide portion 810 is bent toward the airflow source.

[0088] Specifically, the end of the guide portion 810, that is, the end opposite to the partition plate 800, is downward (toward the direction of the airflow source, Figure 7 The arrow in the middle represents the direction of air flow)

[0089] The outflow airflow from the airflow source can be efficiently introduced into the air outlet guiding area 820, thereby improving the air guiding effect.

[0090] As a specific embodiment of the present invention, a portion of the guide portion 810 close to the partition 800 is connected in parallel to the partition 800 .

[0091] Specifically, the guide portion 810 is close to the portion of the partition 800 connected thereto (i.e. Figure 7 The left side portion of the left guide portion 810 is straight and parallel to the partition 800 to form a flat surface, thereby ensuring the structural strength of the guide portion 810 close to the partition 800.

[0092] As a specific embodiment of the present invention, Figure 7 As shown, the partition 710 has at least two, and the length of the first preset number of guide parts 810 away from the airflow source is longer than the length of the second preset number of guide parts 810 close to the airflow source. The first preset number and the second preset number can be set according to actual conditions. Figure 7 The explanation is made by taking the example that the lengths of the five guide portions far from the airflow source are longer than the lengths of the 20 guide portions 810 close to the airflow source.

[0093] Specifically, since the airflow far away from the airflow source is easy to gather on the other side of the air outlet unit, a better air guiding effect can be achieved by lengthening the length of the guide portion 810 far away from the airflow source.

[0094] In addition, simulation evaluation was performed on the single air outlet in the prior art and the air outlet of the present application. Figure 6 and Figure 7 As shown, under the same conveying distance, the end of the single air flow 10 delivered by the single air outlet ( Figure 6 The opening in the middle of the left end has an obvious trend of contraction. The air outlet of the present application is at the end of the main airflow 20 covered by the secondary airflow 30 on both sides ( Figure 7 The opening in the middle of the left end) has a slower trend of closing.

[0095] in addition, Fig.10 and Fig.11 The schematic diagrams of the simulation of the injection of a single airflow 10 and the simulation diagrams of the two secondary airflows 30 covering the primary airflow 20 are respectively shown. In comparison, the air outlet of the present application can achieve a larger air volume at the same distance by conveying the secondary airflow 30 covering the primary airflow 20.

[0096] In addition, the size of multiple air outlets can be adjusted through simulation to ensure that the air volume, wind speed and air supply distance meet the requirements while achieving the purpose of noise reduction.

[0097] A second aspect of the present invention provides an air outlet device, such as Figure 4 and Figure 5 As shown, it may include:

[0098] The air inlet 200 is used to allow an air flow source to enter;

[0099] An air outlet, the air outlet being the air outlet of any embodiment of the first aspect above;

[0100] The air outlet channel 300 is used to connect the air outlet and the air inlet 200. As a specific embodiment of the present invention, the air outlet channel 300 includes at least two, and each air outlet channel 300 is provided with an air outlet.

[0101] Specifically, Figure 4Only two air outlet channels are used as an illustration for illustration. In this embodiment, more than two air outlet channels 300 can be provided, and air outlets are respectively provided on the corresponding air outlet channels 300 to realize air supply. The specific settings can be made according to actual needs, and this application does not limit this.

[0102] As a specific embodiment of the present invention, Figure 5 As shown, the air outlet device may further include a guide block 900. The guide block 900 is close to the air inlet 200 and abuts against the inner wall of the air outlet channel 300 where the air outlet 200 is located, and the guide block 900 is used to guide the airflow to the air outlet.

[0103] That is to say, in order to improve the quality and efficiency of air flow delivery, a guide block 900 can be set in the air outlet channel 300 near the air inlet 200, and the guide block 900 can be matched to the shape of the corresponding air outlet and the air outlet channel 300 to ensure that the quality and efficiency of the air flow delivered from the air inlet 200 to the air outlet are maximized.

[0104] As a specific embodiment of the present invention, Figure 5 As shown, the thickness of the guide block 900 in the air outlet channel 300 gradually increases in a direction away from the air inlet 200 .

[0105] Specifically, on the one hand, the guide block 900 can make the space inside the air outlet channel 300 near the air inlet 200 occupied smaller, thereby ensuring the air intake of the air inlet 200; on the other hand, the guide block 900 can compress the space inside the air outlet channel 300 away from the air inlet 200, thereby increasing the air pressure and flow rate of the air flow inside the air outlet channel 300 toward the multiple air outlet guide areas 620, thereby ensuring that the distant air outlet guide areas 620 can also be allocated sufficient airflow.

[0106] As a specific embodiment of the present invention, Figure 5 As shown, the air outlet also includes at least one partition 800, on which a guide portion 810 extending toward the inner wall of the air outlet channel 300 is formed, and the thickness of the end of the guide block 900 away from the air inlet 200 protruding relative to the inner wall of the air outlet channel 300 of the air outlet is greater than the distance the guide portion 810 extends out of the inner wall of the air outlet channel 300.

[0107] Thus, the airflow entering the air outlet channel 300 from the air inlet 200 is evenly guided to the top of the openings of multiple air outlet guide areas 620 through the guide block 700, so that the guide portion 810 close to the air inlet 200 will not block the airflow entering the air inlet 200, and the air outlet guide area 620 far away from the air inlet 200 can also be allocated sufficient airflow, thereby ensuring the stability of the airflow transmission in the air outlet channel 300, thereby ensuring that the airflow is evenly delivered.

[0108] A third aspect of the present invention provides a fan, such as Figure 4 , Figure 5 As shown, it may include:

[0109] An air inlet 200, the air inlet is used to introduce an air flow source;

[0110] An air outlet, wherein the air outlet is the air outlet of any embodiment of the first aspect above;

[0111] The air outlet channel 300 is used to connect the air outlet and the air inlet 200 .

[0112] As a specific embodiment of the present invention, the fan may further include:

[0113] A housing 100, the housing 100 is used to define an air outlet channel 300;

[0114] An opening 110 is formed in the middle of the shell 100 , and air outlets are disposed on the side walls of the shell 100 on both sides of the opening 110 .

[0115] Specifically, Figure 1-Figure 6 As shown, the housing 100 is annular, and an opening 110 is formed in the middle of the housing 100. The main air outlet 400 and the secondary air outlet channel 500 located at least on one side of the main air outlet channel 400 include at least two groups, and the two groups of main air outlet channels 400 and the secondary air outlet channels 500 located at least on one side of the main air outlet channel 400 are evenly arranged on the housing 100 and on both sides of the opening 110. For example, the main air outlet channel 400 and the secondary air outlet channel 500 located at least on one side of the main air outlet channel 400 can be opened on the front side end surface of the annular housing 100, and the air outlet channel 300 is located inside the annular housing 100 to connect the main air outlet channel 400 and the secondary air outlet channel 500 on the front side end surface of the housing 100. In order to ensure the stability of the air outlet of the air outlet device when delivering air, at least two groups of main air outlet channels 400 and secondary air outlet channels 500 are symmetrically evenly arranged on both sides of the opening 110 of the housing 100.

[0116] It should be noted that a driving system is provided at the bottom of the fan housing 100 to generate an air flow source.

[0117] As a specific embodiment of the present invention, the fan may further include a guide block 900, which is close to the air inlet 200 and abuts against the inner wall of the air outlet channel 300 where the air outlet is located, and is used to guide the airflow to the air outlet.

[0118] As a specific embodiment of the present invention, the thickness of the guide block 900 in the air outlet channel 300 gradually increases in a direction away from the air inlet 200 .

[0119] As a specific embodiment of the present invention, the air outlet further includes at least one partition 800, on which a guide portion 810 extending toward the inner wall of the air outlet channel 300 is formed, and the thickness of the end of the guide block 900 away from the air inlet 200 protruding relative to the inner wall of the air outlet channel 300 where the air outlet is located is greater than the distance the guide portion 810 extends from the inner wall of the air outlet channel 300. It can be understood that the configuration of the guide block 900 is the same as that of the guide block 900 described in the above embodiment, and will not be described in detail here.

[0120] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived based on the content disclosed in the present invention without departing from the spirit and scope of the present invention.
