Description

Technical Field

[0001] The present application relates to household electrical appliance technology, and in particular to an air outlet and a hair care appliance. Background Art

[0002] Hair care appliances (such as hair dryers) are common household appliances and are widely used in people's daily lives to facilitate hair care. With the development of technology, people's expectations for hair dryers are getting higher and higher. In order to make hair dryers easy to carry, they are expected to be miniaturized, lightweight, and have high blowing efficiency to meet users' needs for quick hair drying.

[0003] However, when the hair dryer is miniaturized while meeting the blowing efficiency, the air outlet is also smaller accordingly, which results in a small air outlet area of ​​the hair dryer, affecting the overall air volume of the hair dryer, causing excessive local air volume loss after the hair dryer is connected to the styling accessories, and the overall utilization efficiency of the hair dryer after the styling accessories are connected is low;

[0004] In addition, when the hair dryer is miniaturized as a whole, it is easy for the overall heat dissipation flow path inside the hair dryer to be blocked, thereby affecting the heat dissipation performance of the hair dryer as a whole. Utility Model Content

[0005] In order to overcome the above-mentioned defects in the related art, the purpose of the present application is to provide an air outlet and a hair care appliance, which can increase the air outlet volume, increase the air outlet area, and enable the hair dryer to have a better heat dissipation effect.

[0006] In one aspect, the present application provides an air outlet member, comprising an air outlet wall, wherein the air outlet wall is provided with a first annular air outlet and a second annular air outlet, wherein the second air outlet is spaced apart and radially inward of the first air outlet;

[0007] Wherein, the ratio of the inner diameter r1 of the first air outlet to the inner diameter r2 of the second air outlet is between 1.2 and 1.6.

[0008] The present application arranges the first air outlet and the second air outlet at intervals in the radial direction of the air outlet wall surface, and limits the value of r1:r2 to between 1.2 and 1.6. Compared with the single air outlet in the related art, the width of the air outlet in the radial direction of the air outlet wall surface is increased while the overall area of ​​the air outlet remains unchanged, thereby improving the air output of the hair dryer, increasing the air outlet area of ​​the air outlet, and enabling the hair dryer to have a better heat dissipation effect.

[0009] On the other hand, the present application provides an air outlet member, including an air outlet wall surface, wherein the air outlet wall surface is provided with a first annular air outlet and a second air outlet, wherein the second air outlet is arranged radially inward of the first air outlet at intervals;

[0010] Wherein, the ratio of the outer diameter R1 of the first air outlet to the outer diameter R2 of the second air outlet is between 1.2 and 1.5.

[0011] In the present application, the first air outlet and the second air outlet are spaced apart in the radial direction of the air outlet wall surface, and the value of R1:R2 is limited to between 1.2 and 1.5. Compared with the single air outlet in the related art, the air outlet nozzle uses the air flow principle to change the radial width of the air outlet to adjust the air outlet angle and wind direction of the hair dryer, thereby enhancing the air outlet wind force.

[0012] In another aspect, the present application provides an air outlet member, comprising an air outlet wall surface, along which a first air outlet and a second air outlet of equal width are provided, wherein the second air outlet is spaced apart and arranged radially inward of the second air outlet;

[0013] Wherein, the ratio of the width W1 of the first air outlet to the width W2 of the second air outlet is between 0.8 and 0.95.

[0014] In the present application, the first air outlet and the second air outlet are spaced apart in the radial direction of the air outlet wall, and the value of W1:W2 is limited to between 0.8-0.95. Compared with the single air outlet in the related art, the first air outlet and the second air outlet ensure the width of the overall air outlet, so that the airflow direction of the air outlet is unified and stable, and the air volume and air pressure at the air outlet are increased, thereby improving the efficiency of users using the hair dryer.

[0015] In a possible implementation, an annular wall is provided along the circumference of the air outlet wall surface and protrudes toward the air inlet. The annular wall is connected to the air outlet wall surface and together define a fluid flow channel.

[0016] The present application defines a fluid flow channel by means of the annular wall and the air outlet wall surface, so that the air outlet of the hair dryer can be introduced into the fluid flow channel and then blown out through the first air outlet and the second air outlet.

[0017] In a possible implementation, the air outlet wall is provided with a plurality of the first air outlets and a plurality of the second air outlets, and the plurality of the first air outlets and the plurality of the second air outlets are arranged at intervals around the center of the air outlet wall; a first guide rib is provided between the plurality of first air outlets, and the first guide rib is arranged at intervals between two adjacent first air outlets;

[0018] Second guide ribs are arranged between the plurality of second air outlets, and the second guide ribs are arranged at intervals between two adjacent second air outlets.

[0019] The present application sets a first guide rib between two adjacent first air outlets and a second guide rib between two adjacent second air outlets, so that the first guide rib and the second guide rib can be used to guide the airflow direction in the first air outlet and the second air outlet respectively, optimize the distribution of the airflow, enhance the stability of the airflow, and make the air outlet generate soft wind, so as to reduce the impact of the airflow on the user's skin.

[0020] In a possible implementation, along the axial direction of the fluid flow channel, the width of the first guide rib gradually decreases from the side of the air outlet wall surface to the side of the fluid flow channel, and the width of the second guide rib gradually decreases from the side of the air outlet wall surface to the side of the fluid flow channel.

[0021] Through the above-mentioned structure, the present application makes the air flow in the first air outlet and the second air outlet smoother, which is beneficial to increasing the air output and power of the hair dryer.

[0022] In a possible implementation, the maximum width of the first guide rib is less than or equal to 2 mm; the maximum width of the second guide rib is less than or equal to 2 mm.

[0023] The present application limits the maximum width of the first guide rib and the second guide rib to within 2 mm, thereby ensuring that the first air outlet and the second air outlet have better airflow distribution and airflow stability, while also ensuring that the air output of the first air outlet and the second air outlet is larger.

[0024] In a possible implementation, the plurality of first guide ribs and the plurality of second guide ribs are symmetrically or asymmetrically arranged in the radial direction or the axial direction of the air outlet wall.

[0025] The present application can use the first guide rib to support the first air outlet to enhance the structural strength of the first air outlet and prevent deformation or damage; correspondingly, the second guide rib can be used to support the second air outlet to enhance the structural strength of the second air outlet and prevent deformation or damage. When multiple first guide ribs and multiple second guide ribs are staggered in the radial or axial direction of the air outlet wall, multiple first air outlets and second air outlets are asymmetrically arranged on the air outlet wall to reduce the resonance between the first air outlet and the second air outlet when blowing, reduce wind noise, and make the air outlet closer to natural wind.

[0026] In a possible implementation, in a plane perpendicular to the axis of the fluid flow channel, the projection of the air outlet wall is circular, the projections of the plurality of first air outlets are arranged in a first circular ring around the projection center of the air outlet wall, and the projections of the plurality of second air outlets are arranged in a second circular ring around the projection center of the air outlet wall.

[0027] The present application arranges the plurality of first air outlets and the plurality of second air outlets into a circular ring shape, so that the first air outlets and the second air outlets have a larger area on the circular air outlet wall surface, which is beneficial to increasing the air outlet volume and the air outlet area.

[0028] In a possible implementation, the plurality of first air outlets are concentrically arranged with the plurality of second air outlets, and the centers of the plurality of first air outlets and the centers of the plurality of second air outlets are both located on the axis of the air outlet wall.

[0029] The present application ensures the uniformity of air outlets at each of the first air outlets and the second air outlets by arranging the centers of the circles of the plurality of first air outlets and the plurality of second air outlets on the axis of the air outlet wall.

[0030] In a possible implementation, a partition rib is provided between the first air outlet and the second air outlet, and a size of the partition rib is 1-3 mm along the radial direction of the air outlet wall.

[0031] The present application limits the size of the dividing rib between the first air outlet and the second air outlet to within 1-3 mm, so that the airflow in the first air outlet and the second air outlet has a stronger compression effect, which is beneficial to increasing the air output and reducing the noise of the whole machine.

[0032] In a possible implementation, along the radial direction of the air outlet wall, R1-r2 is 3-8 mm.

[0033] The present application limits R1-r2 within 3-8 mm, so that the airflow forms a strong wall effect between the first air outlet and the second air outlet, thereby improving the gas compression effect.

[0034] In a possible implementation, a mounting portion is further provided on the air outlet wall surface, and the second air outlet surrounds the outer side of the mounting portion;

[0035] The mounting portion has a hemispherical surface on one side facing the fluid flow channel.

[0036] The present application sets the mounting portion to be a hemispherical surface on one side facing the fluid flow channel, so that the mounting portion can be used to guide the airflow direction in the fluid flow channel, so that the airflow accumulates toward the first air outlet and the second air outlet, which is beneficial to increase the air output.

[0037] In a possible implementation, an angle between a tangent line of the hemispherical surface and the air outlet wall surface is less than 50°.

[0038] Through the above-mentioned structure, the present application can increase the air output in the first air outlet and the second air outlet, making the overall air output of the hair dryer softer. When the user uses a styling accessory to connect the hair dryer, it can not only meet the user's styling needs but also protect the user's skin without causing the loss of air volume of the styling accessory.

[0039] In a possible implementation, along the axis of the fluid flow channel, the radius of the wind surface of the air outlet member at a distance of 100 mm from the wind outlet wall surface of the annular wall is greater than or equal to 100 mm.

[0040] Through the above structure, the present application ensures that the radius of the wind surface of the air outlet piece at a distance of 100 mm from the air outlet wall surface of the annular wall is greater than or equal to 100 mm, thereby ensuring that the hair dryer has a strong air outlet volume and air outlet area to meet the user's usage needs.

[0041] On the other hand, the present application provides a hair care appliance, comprising the air outlet member as described above.

[0042] The hair care device of the present application has a higher air output volume and a larger air output area, while improving the heat dissipation effect of the entire miniaturized hair dryer. BRIEF DESCRIPTION OF THE DRAWINGS

[0067] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in combination with the drawings 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.

[0068] Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0069] As described in the background technology, the miniaturized and lightweight hair dryers in the related art solutions often have problems such as small air outlet area and air volume, and poor heat dissipation.

[0070] In view of this, the embodiments of the present application aim to provide an air outlet and a hair care device, by arranging a first air outlet and a second air outlet at intervals, and limiting the radius, width and other values ​​of the first air outlet and the radius, width of the second air outlet within a certain range. Compared with the single air outlet in the related art, the width of the air outlet in the radial direction of the air outlet wall is increased while the overall area of ​​the air outlet remains unchanged, thereby increasing the air outlet volume, increasing the air outlet area, and enabling the hair dryer to have a better heat dissipation effect.

[0071] The contents of the embodiments of the present application will be described in detail below in conjunction with the accompanying drawings so that those skilled in the art can understand the contents of the present application in more detail.

[0072] Figure 1 A simplified structural diagram of an air outlet member provided in an embodiment of the present application at a first viewing angle; Figure 2 A simplified structural diagram of an air outlet member provided in an embodiment of the present application at a second viewing angle; Figure 3 A front view of an air outlet member provided in an embodiment of the present application; Figure 4 for Figure 3 In the description of this embodiment, the radial direction of the air outlet wall 200 refers to the direction indicated by any straight line passing through the center O of the air outlet wall 200; the circumferential direction of the air outlet wall 200 refers to the direction along the edge of the air outlet wall 200; the axis T of the fluid flow channel 110 refers to the straight line perpendicular to the air outlet wall 200 and passing through the center O of the air outlet wall 200.

[0073] Please refer to Figure 1-Figure 4 The present embodiment provides an air outlet member 10, including an air outlet wall surface 200, on which a first air outlet 300 and a second air outlet 400 are provided in an annular shape, and the second air outlet 400 is arranged at intervals on the radial inner side of the first air outlet 300 (i.e., part of the first air outlet 300 and part of the second air outlet 400 are located on the same diameter of the air outlet wall surface 200, and the second air outlet 400 is arranged close to the center O of the air outlet wall surface 200). In the present embodiment, the first air outlet 300 and the second air outlet 400 are arranged in an annular shape around the air outlet wall surface 200, for example, they may be in the shape of a circular ring, a rectangular ring, a triangular ring, etc., and the shapes of the first air outlet 300 and the second air outlet 400 may be the same or different.

[0074] The ratio of the inner diameter r1 of the first air outlet 300 to the inner diameter r2 of the second air outlet 400 is between 1.2 and 1.6.

[0075] It can be understood that the first air outlet 300 includes a first side and a second side opposite to each other, and the first side faces the outer edge of the air outlet wall surface 200 of the annular wall 100. The inner diameter r1 of the first air outlet 300 refers to the distance between the second side of the first air outlet 300 and the center O of the air outlet wall surface 200. The second air outlet 400 includes a third side and a fourth side opposite to each other, and the fourth side faces the center of the air outlet wall surface 200 of the annular wall 100; the inner diameter r2 of the second air outlet 400 refers to the distance between the fourth side of the second air outlet 400 and the center O of the air outlet wall surface 200.

[0076] Compared with the single air outlet solution in the related art, this embodiment limits the values ​​of r1:r2 to between 1.2 and 1.6, so that the radial width of the air outlet on the air outlet wall 200 can be increased (that is, the sum of the radial dimensions of the first air outlet 300 and the second air outlet 400 on the air outlet wall 200 is greater than the radial dimensions of the single air outlet on the air outlet wall 200 in the related art) while keeping the overall area of ​​the air outlet unchanged (that is, the sum of the areas of the first air outlet 300 and the second air outlet 400 in this embodiment is equal to the area of ​​the single air outlet in the related art), thereby improving the air output of the hair dryer, increasing the air outlet area of ​​the air outlet, and enabling the hair dryer to have a better heat dissipation effect, so as to meet the user's demand for a miniaturized and lightweight hair dryer.

[0077] Figure 5 This is a schematic diagram of the air volume under different values ​​of r2 of the present application; wherein, the horizontal axis represents the value of r2, the vertical axis represents the air volume, the value of r1 remains fixed, and only the value of r2 is changed, thereby changing the value of r1:r2.

[0078] based on Figure 5 It can be concluded that when the value of r1 is fixed, as the value of r2 increases, the air volume also gradually increases; when the value of r2 is between 14-15mm, the air volume reaches the maximum; when the value of r2 exceeds 15mm, the air volume decreases rapidly. When the value of r2 is between 14-15mm, the value of r1:r2 is just between 1.2-1.6. Therefore, limiting the value of r1:r2 to between 1.2-1.6 can increase the air volume of the hair dryer, increase the air outlet area of ​​the air outlet, and enable the hair dryer to have a better heat dissipation effect, so as to meet the user's demand for miniaturized and lightweight hair dryers.

[0079] The present embodiment further provides an air outlet member 10, including an air outlet wall surface 200, on which a first air outlet 300 and a second air outlet 400 are provided in an annular shape, and the second air outlet 400 is arranged at intervals on the radial inner side of the first air outlet 300 (i.e., part of the first air outlet 300 and part of the second air outlet 400 are located on the same diameter of the air outlet wall surface 200, and the second air outlet 400 is arranged close to the center O of the air outlet wall surface 200). In the present embodiment, the first air outlet 300 and the second air outlet 400 are arranged in an annular shape around the air outlet wall surface 200, for example, they may be in the shape of a circular ring, a rectangular ring, a triangular ring, etc., and the shapes of the first air outlet 300 and the second air outlet 400 may be the same or different.

[0080] The ratio of the outer diameter R1 of the first air outlet 300 to the outer diameter R2 of the second air outlet 400 is between 1.2 and 1.5.

[0081] It can be understood that the first air outlet 300 includes a first side and a second side opposite to each other, and the first side faces the outer edge of the air outlet wall surface 200 of the annular wall 100. The outer diameter R1 of the first air outlet 300 refers to the distance between the first side of the first air outlet 300 and the center O of the air outlet wall surface 200. The second air outlet 400 includes a third side and a fourth side opposite to each other, and the fourth side faces the center of the air outlet wall surface 200 of the annular wall 100; the outer diameter R2 of the second air outlet 400 refers to the distance between the third side of the second air outlet 400 and the center O of the air outlet wall surface 200.

[0082] Compared with the single air outlet solution in the related art, this embodiment limits the value of R1:R2 to between 1.2-1.5. By utilizing the air flow principle, the air outlet nozzle changes the radial width of the air outlet to adjust the air outlet angle and wind direction of the hair dryer, thereby enhancing the air outlet wind force.

[0083] Figure 6 It is a schematic diagram of the air volume under different values ​​of R2 of the present application; wherein, the air outlet area (i.e., the sum of the areas of the first air outlet 300 and the second air outlet 400) is constant, and only the value of R2 is changed, thereby changing the value of R1:R2.

[0084] based on Figure 6 It can be concluded that when the air outlet area is constant, as the value of R2 increases, the air volume also gradually increases; when the value of R2 is between 15-15.5mm, the air volume reaches the maximum; when the value of R2 exceeds 15.5mm, the air volume slowly decreases. When the value of R2 is between 15-15.5mm, the value of R1:R2 is exactly between 1.2-1.5. Therefore, limiting the value of R1:R2 to between 1.2-1.5 can increase the air volume of the hair dryer and enhance the wind force.

[0085] The present embodiment further provides an air outlet member 10, including an air outlet wall surface 200, on which a first air outlet 300 and a second air outlet 400 are provided in an annular shape, and the second air outlet 400 is arranged at intervals on the radial inner side of the first air outlet 300 (i.e., part of the first air outlet 300 and part of the second air outlet 400 are located on the same diameter of the air outlet wall surface 200, and the second air outlet 400 is arranged close to the center O of the air outlet wall surface 200). In the present embodiment, the first air outlet 300 and the second air outlet 400 are arranged in an annular shape around the air outlet wall surface 200, for example, they may be in the shape of a circular ring, a rectangular ring, a triangular ring, etc., and the shapes of the first air outlet 300 and the second air outlet 400 may be the same or different.

[0086] The ratio of the width W1 of the first air outlet 300 to the width W2 of the second air outlet 400 is between 0.8 and 0.95.

[0087] It can be understood that the first air outlet 300 includes a first side and a second side opposite to each other, and the first side faces the outer edge of the air outlet wall surface 200 of the annular wall 100. The inner diameter r1 of the first air outlet 300 refers to the distance between the second side of the first air outlet 300 and the center O of the air outlet wall surface 200; the outer diameter R1 of the first air outlet 300 refers to the distance between the first side of the first air outlet 300 and the center O of the air outlet wall surface 200; the width W1 of the first air outlet 300 is R1-r1. The second air outlet 400 includes a third side and a fourth side relative to each other, and the fourth side faces the center of the air outlet wall 200 of the annular wall 100; the inner diameter r2 of the second air outlet 400 refers to the distance between the fourth side of the second air outlet 400 and the center O of the air outlet wall 200; the outer diameter R2 of the second air outlet 400 refers to the distance between the third side of the second air outlet 400 and the center O of the air outlet wall 200; the width W2 of the second air outlet 400 is R2-r2.

[0088] Compared with the single air outlet solution in the related art, this embodiment limits the value of W1:W2 to between 0.8-0.95. The first air outlet 300 and the second air outlet 400 ensure the width of the overall air outlet, so that the airflow direction of the air outlet is uniform and stable, and the air volume and wind pressure at the air outlet are increased, thereby improving the user's efficiency in using the hair dryer.

[0089] In some embodiments, an annular wall 100 is provided along the circumference of the air outlet wall surface 200 protruding toward the air inlet 900, and the annular wall 100 is connected to the air outlet wall surface 200 and jointly defines a fluid flow channel 110. In this embodiment, the annular wall 100 is generally cylindrical, and the fluid flow channel 110 is connected to the inside of the hair dryer. The wind generated by the hair dryer passes through the fluid flow channel 110 and is finally blown out from the first air outlet 300 and the second air outlet 400.

[0090] In this embodiment, the fluid flow channel 110 is defined by the annular wall 100 and the air outlet wall surface 200 , so that the air outlet of the hair dryer can be introduced into the fluid flow channel 110 and then blown out through the first air outlet 300 and the second air outlet 400 .

[0091] In some embodiments, a plurality of first air outlets 300 and a plurality of second air outlets 400 are disposed on the air outlet wall 200 , and the plurality of first air outlets 300 and the plurality of second air outlets 400 are arranged at intervals around a center O of the air outlet wall 200 .

[0092] A first guide rib 500 is disposed between the plurality of first air outlets 300 , and the first guide rib 500 is disposed at intervals between two adjacent first air outlets 300 .

[0093] Second guide ribs 600 are disposed between the plurality of second air outlets 400 , and the second guide ribs 600 are disposed at intervals between two adjacent second air outlets 400 .

[0094] In this embodiment, a first guide rib 500 is set between two adjacent first air outlets 300, and a second guide rib 600 is set between two adjacent second air outlets 400, so that the first guide rib 500 and the second guide rib 600 can be used to guide the airflow direction in the first air outlet 300 and the second air outlet 400 respectively, optimize the distribution of the airflow, enhance the stability of the airflow, and make the air outlet generate soft wind, so as to reduce the impact of the airflow on the user's skin.

[0095] Furthermore, along the axis T of the fluid flow channel 110 , the width of the first guide rib 500 gradually decreases from the air outlet wall 200 side to the fluid flow channel 110 side, and the width of the second guide rib 600 gradually decreases from the air outlet wall 200 side to the fluid flow channel 110 side.

[0096] Through the above structure, this embodiment makes the air flow in the first air outlet 300 and the second air outlet 400 smoother, which is beneficial to increase the air output and power of the whole machine.

[0097] Preferably, the maximum width D1 of the first guide rib 500 of this embodiment is less than or equal to 2 mm; the maximum width D2 of the second guide rib 600 is less than or equal to 2 mm.

[0098] In this embodiment, the maximum width of the first guide rib 500 and the second guide rib 600 is limited to within 2 mm, so that the air volume of the first air outlet 300 and the second air outlet 400 is relatively large while ensuring that the first air outlet 300 and the second air outlet 400 have good air flow distribution and air flow stability.

[0099] In some embodiments, Figure 3As shown, the plurality of first guide ribs 500 and the plurality of second guide ribs 600 of this embodiment are symmetrically arranged in the radial or axial direction of the air outlet wall surface 200, for example, a one-to-one correspondence can be achieved when folded in the axial or radial direction.

[0100] In this embodiment, the first guide rib 500 can be used to support the first air outlet 300 to enhance the structural strength of the first air outlet 300 and prevent deformation or damage; correspondingly, the second guide rib 600 can be used to support the second air outlet 400 to enhance the structural strength of the second air outlet 400 and prevent deformation or damage.

[0101] In other embodiments, the plurality of first guide ribs 500 and the plurality of second guide ribs 600 of this embodiment are asymmetrically arranged in the radial or axial direction of the air outlet wall surface 200 , for example, in a staggered distribution form.

[0102] In this embodiment, a plurality of first guide ribs 500 and a plurality of second guide ribs 600 are staggered in the radial direction of the air outlet wall 200, so that a plurality of first air outlets 300 and second air outlets 400 are asymmetrically arranged on the air outlet wall 200, so as to reduce the resonance between the first air outlets 300 and the second air outlets 400 when blowing air, reduce wind noise, and make the air outlet closer to natural wind.

[0103] In some embodiments, Figure 3 As shown, in a plane perpendicular to the axis T of the fluid flow channel 110, the projection of the air outlet wall 200 is circular, the projections of multiple first air outlets 300 are arranged in a first circular ring around the projection center of the air outlet wall 200, and the projections of multiple second air outlets 400 are arranged in a second circular ring around the projection center of the air outlet wall.

[0104] In this embodiment, the plurality of first air outlets 300 and the plurality of second air outlets 400 are arranged in a circular ring shape, so that the first air outlets 300 and the second air outlets 400 have a larger area on the circular air outlet wall surface 200, which is beneficial to increase the air volume and the air outlet area.

[0105] Furthermore, the first air outlets 300 and the second air outlets 400 of this embodiment are arranged concentrically, and the centers of the first air outlets 300 and the second air outlets 400 are both located on the axis of the air outlet wall 200. The axis of the air outlet wall 200 coincides with the axis T of the fluid flow channel 110.

[0106] In this embodiment, the centers of the first air outlet 300 and the second air outlet 400 are both arranged on the axis of the air outlet wall 200 , thereby ensuring the uniformity of air outlet at each location of the first air outlet 300 and the second air outlet 400 .

[0107] Please continue to refer to Figure 1 and Figure 3 In this embodiment, a partition rib 700 is provided between the first air outlet 300 and the second air outlet 400. Along the radial direction of the air outlet wall surface 200, a size D3 of the partition rib 700 is 1-3 mm.

[0108] In this embodiment, by limiting the size D3 of the dividing rib 700 between the first air outlet 300 and the second air outlet 400 to within 1-3 mm, the airflow in the first air outlet 300 and the second air outlet 400 can have a stronger compression effect, which is beneficial to increasing the air output and reducing the noise of the whole machine.

[0109] Furthermore, along the radial direction of the air outlet wall surface 200, R1-r2 is 3-8 mm.

[0110] In this embodiment, R1-r2 is limited within 3-8 mm, so that the airflow forms a strong wall effect between the first air outlet 300 and the second air outlet 400, thereby improving the gas compression effect.

[0111] In some embodiments, the air outlet wall surface 200 of this embodiment is further provided with a mounting portion 800, and the second air outlet 400 surrounds the outer side of the mounting portion 800. The side of the mounting portion 800 facing the fluid flow channel 110 is hemispherical.

[0112] In this embodiment, the mounting portion 800 is arranged to be hemispherical on one side facing the fluid flow channel 110, so that the mounting portion 800 can be used to guide the airflow direction in the fluid flow channel 110, so that the airflow accumulates toward the first air outlet 300 and the second air outlet 400, which is beneficial to increase the air output.

[0113] Furthermore, if Figure 4 As shown, in this embodiment, the angle α between the tangent line of the hemispherical surface and the air outlet wall surface 200 is less than 50°. The tangent line of the hemispherical surface refers to a straight line on the hemispherical surface that is perpendicular to the radius.

[0114] Through the above structure, this embodiment can increase the air volume in the first air outlet 300 and the second air outlet 400, making the overall air output of the hair dryer softer. When the user uses a styling accessory to connect the hair dryer, it can not only meet the user's styling needs but also protect the user's skin without causing the loss of air volume of the styling accessory.

[0115] Figure 7 This is a schematic diagram of the air outlet area when the air outlet member provided in one embodiment of the present application and the air outlet member in the related art are used. Figure 7 In this embodiment, along the axis T of the fluid flow channel 110, the radius L1 of the wind surface of the air outlet member 10 at a distance of 100 mm from the wind outlet wall surface is greater than or equal to 100 mm.

[0116] Through the above structure, the present embodiment ensures that the radius L1 of the wind surface of the air outlet member 10 at a distance of 100 mm from the air outlet wall is greater than or equal to 100 mm, thereby ensuring that the hair dryer has a strong air outlet volume and air outlet area to meet the user's usage requirements.

[0117] The effects of this embodiment are described in detail below with reference to the accompanying drawings.

[0118] Figure 7 The figure shows the wind outlet area of ​​the fan after the air outlet of the air outlet member is blown out, S1 in the figure is a schematic diagram of the wind outlet area when the air outlet member with a single air outlet in the related art is used; S2 and S3 are schematic diagrams of the increased wind outlet area when the air outlet member of this embodiment is used compared with the air outlet member with a single air outlet in the related art. Figure 5 It can be seen that since the first air outlet 300 and the second air outlet 400 are simultaneously arranged on the air outlet wall 200 in this embodiment, the air outlet area of ​​the air outlet piece is the sum of S1, S2 and S3, which is much larger than the air outlet area S1 of the air outlet piece with a single air outlet in the related technology. Therefore, the air outlet piece 10 of this embodiment can increase the air outlet volume and the air outlet area.

[0119] Figure 8 A gas flow diagram when the air outlet device in the related art is used; Fig. 9 A gas flow diagram when the air outlet member provided in one embodiment of the present application is in use.

[0120] Please refer to Figure 8 When the air outlet device 1000 in the related art is connected to the hair dryer 20 and the styling accessory 30, the air outlet 1100 of the air outlet device 1000 is set close to the edge of the air outlet device 1000, and part of the hot air U1 generated by the heating component 21 of the hair dryer 20 can be sent into the styling accessory 30 or blown into the outside air through the air outlet 1100, while the other part of the hot air U2 will be blocked by the relevant components on the air outlet device 1000 and accumulated in the fluid flow channel and cannot be discharged in time, thereby causing the heat generated by the hair dryer 20 to be unable to be dissipated in time.

[0121] Please refer to Fig. 9When the air outlet piece 10 of this embodiment is connected to the hair dryer 20 and the styling accessory 30, the first air outlet 300 of the air outlet piece 10 is arranged close to the edge of the air outlet piece 10, and the second air outlet 400 is close to the axis of the fluid flow channel in the air outlet piece 10. The hot air U3 generated by the heating component 21 of the hair dryer 20 can be sent into the styling accessory 30 or blown into the outside air via the first air outlet 300 and the second air outlet 400. Since the sum of the radial dimensions of the first air outlet 300 and the second air outlet 400 on the air outlet wall surface is larger than the radial dimension of the air outlet 1100 in the related art, U3 is larger than U1, that is, the air outlet piece of this embodiment has a larger air outlet volume, thereby bringing out more heat generated by the heating component 21, which is beneficial to the heat dissipation of the hair dryer 20.

[0122] Please continue to refer to Figure 8 In addition, when the air outlet 1100 supplies air into the modeling attachment 30, due to the small size of the air outlet 1100, the air outlet generates a large noise inside the modeling attachment 30, thereby affecting the user's experience.

[0123] Please refer to Fig. 9 When the first air outlet 300 and the second air outlet 400 of this embodiment deliver air into the styling accessory 30, since the overall size of the air outlet is increased, the noise generated by the air outlet inside the styling accessory 30 is smaller, thereby improving the user experience.

[0124] From the above description, it can be seen that in this embodiment, by setting the first air outlet 300 and the second air outlet interval, and limiting the value of r1:r2 to between 1.2-1.6, the value of R1:R2 to between 1.2-1.5, and / or the value of W1:W2 to between 0.8-0.95, compared with the single air outlet in the related art, the width of the air outlet in the radial direction of the air outlet wall 200 is increased while the overall area of ​​the air outlet remains unchanged, thereby increasing the air outlet volume, increasing the air outlet area, and enabling the hair dryer to have a better heat dissipation effect.

[0125] This embodiment also provides a hair care device, including the air outlet member 10 mentioned above.

[0126] It can be understood that, due to the use of the above-mentioned air outlet member, the hair care device of this embodiment has a higher air outlet volume and a larger air outlet area, while improving the heat dissipation effect of the miniaturized hair dryer.
