Description

TECHNICAL FIELD

[0001] The present application relates to an air outlet structure and an indoor temperature control device using the same. BACKGROUND

[0002] Air supply devices with heating or cooling functions are widely used in people's daily life, and the market demand for air supply devices with heating or cooling functions (such as warm air ventilation devices used in bathrooms) is increasing. However, the existing air supply devices on the market have the problem of narrow air outlet coverage, which cannot provide uniform temperature regulation effect, causing inconvenience to users. For example, the existing warm air ventilation devices used in bathrooms have the problem of small blowing range. When the existing warm air ventilation device is in a warm air working mode, the warm air flow emitted can only blow directly to the head of the human body. Due to the limited flow dispersion range, and the density of the warm air flow is less than the density of the indoor cold air, the warm air flow is only limited to disperse in the space area of the upper limbs of the human body, and cannot cover the lower body area of the human body, which cannot provide uniform temperature regulation effect, causing inconvenience to users. SUMMARY

[0003] According to one aspect of the present application, in order to overcome the defects of the prior art described above, an air outlet structure is provided, which comprises a housing, a flow guide, a first air duct and a second air duct. The housing is provided with an air outlet and an air outlet working side facing a wind receiving object. The air outlet extends to the air outlet working side. The second air duct is connected to the flow guide. The flow guide path is arranged to radiate and disperse from the second air duct to the peripheral area of the air outlet working side. The air outlet direction of the first air duct is arranged to radiate and disperse from the first air duct to the middle area of the air outlet working side through the air outlet. The air outlet direction of the first air duct intersects with the flow guide path of the flow guide at the air outlet. When the first air duct and the second air duct obtain air source at the same time, the first air flow emitted by the first air duct and the second air flow emitted by the second air duct intersect and mix to generate an air supply flow. The coverage range of the air supply flow extends from the peripheral area of the air outlet working side to the middle area of the air outlet working side.

[0004] Thus, when the present application is assembled into a specific air supply device (such as a fan, a cooler, an air conditioner, etc.), the first air duct and the second air duct of the present application are both connected with the air source, the air outlet working side of the shell is arranged on the air supply panel of the air supply device, the air supply panel faces the air receiving object, that is, the air outlet working side faces the air receiving object, when the air supply device is working, the air source generating unit of the air supply device is started, and the generated air source enters the first air duct and the second air duct respectively. Since the air outlet direction of the first air duct is arranged to radiate and disperse from the air outlet to the middle region of the air outlet working side, the first airflow emitted by the first air duct blows towards the middle region of the air outlet working side, and since the flow guiding path of the flow guiding piece is arranged to radiate and disperse from the second air duct to the peripheral region of the air outlet working side through the air outlet, the second airflow emitted by the second air duct blows and disperses towards the peripheral region of the air outlet working side after being guided by the flow guiding piece. The first airflow and the second airflow meet and mix at the air outlet to generate an air supply airflow, and the first airflow pushes part of the second airflow to bias towards the direction of the middle region of the air outlet working side, so that the coverage range of the air supply airflow generated by the mixing of the first airflow and the second airflow extends from the peripheral region of the air outlet working side to the middle region of the air outlet working side. Whether the air receiving object is directly opposite the air outlet working side or obliquely opposite the air outlet working side, it can receive the air supply airflow, and the air supply device has the characteristics of wide air outlet coverage, can uniformly provide temperature regulation effect, and brings convenience to the user.

[0005] In some embodiments, the air outlet is provided with a plurality of air supply directions, the flow guiding piece is provided with a plurality of flow guiding paths, the plurality of flow guiding paths are arranged one by one corresponding to the plurality of air supply directions, and the air outlet range of the first air duct is arranged to cover all the flow guiding paths of the flow guiding piece, so that when the first air duct and the second air duct simultaneously obtain the air source, the air outlet emits air supply airflow to multiple directions respectively.

[0006] In this way, by arranging the air outlet to have a plurality of air supply directions, and arranging the flow guiding piece to have a plurality of flow guiding paths corresponding to the air supply directions one by one, when the first air duct and the second air duct simultaneously obtain the air source, the air outlet emits air supply airflow to multiple directions respectively, which further enhances the air outlet coverage of the air supply device using the air outlet structure.

[0007] In some embodiments, the air outlet is arranged in a circular ring shape, the plurality of air outlet directions of the air outlet are arranged to radiate along different radial angles respectively, the flow guiding piece is arranged in a conical shape, the conical bottom of the flow guiding piece is aligned with the middle position of the air outlet, and the conical top of the flow guiding piece is aligned with the second air duct, so that the inclination direction of the conical surface of the flow guiding piece extends towards the peripheral region of the air outlet working side, and the plurality of flow guiding paths are arranged to extend along the conical surface of the flow guiding piece at different radial angles respectively.

[0008] In this way, since the conical top of the flow guide is aligned with the second air duct, and the conical surface of the flow guide is formed by 360° rotation, when the second air duct obtains the air source, the second airflow extends along the conical surface of the flow guide from each radial angle to the peripheral area of the air outlet working side, so that the air outlet has the effect of 360° air outlet, and has the characteristic of uniform air outlet.

[0009] In some embodiments, the shell comprises a barrel, and the first air duct and the second air duct are both arranged in the barrel, and the barrel and the conical base of the flow guide jointly enclose the circular air outlet; the first air duct is arranged in a spiral shape along the inner wall of the barrel, and the second air duct is arranged at the middle position of the barrel, and the first air duct is arranged around the second air duct; when the first air duct obtains the air source, the first airflow in the first air duct blows towards the air outlet while being spirally blown along the inner wall of the barrel, so that the air outlet range of the first air duct covers the air outlet along the inner wall of the barrel.

[0010] In this way, the conical base of the flow guide is nested with the edge of the barrel, and an annular gap is formed between the barrel and the conical base of the flow guide, i.e., the barrel and the conical base of the flow guide jointly enclose the circular air outlet; when the first air duct obtains the air source, the first airflow in the first air duct blows towards the air outlet while being spirally blown along the inner wall of the barrel, i.e., the movement track of the first airflow covers the entire circumference of the barrel, so that the air outlet range of the first air duct covers the air outlet along the inner wall of the barrel; since the entire flow guide path of the flow guide passes through the air outlet, i.e., the air outlet range of the first air duct is arranged to cover the entire flow guide path of the flow guide; in addition, the first air duct arranged in a spiral shape guides the first airflow to be spirally blown, so that the first airflow is 360° dispersedly blown outwards from the air outlet, so that the air volume distribution is more uniform.

[0011] In some embodiments, the second air duct is arranged in a spiral shape, so that when the second air duct obtains the air source, the second airflow in the second air duct is radiated and dispersed from the air outlet to the peripheral area of the air outlet working side while being spirally blown from each radial angle of the air outlet.

[0012] In this way, when the second air duct obtains the air source, the second airflow is spirally rotated under the guidance of the second air duct, and the second airflow is radiated and dispersed from the air outlet to the peripheral area of the air outlet working side while being spirally blown from each radial angle of the air outlet; the first airflow and the second airflow are 360° dispersedly blown outwards from the air outlet in the same spiral direction, so that the air volume distribution of the air supply airflow generated by the intersection and mixing of the first airflow and the second airflow is more uniform.

[0013] In some embodiments, the first air duct is provided with a first contraction region, and the cross-sectional area of the first contraction region gradually decreases along the air outlet direction of the first air duct.

[0014] In this way, when the first airflow moves along the first air duct, as the space is reduced when passing through the first contraction area, the volume of the first airflow is compressed, and the wind speed of the first airflow is increased, so that the first airflow can be blown further and the blowing coverage is wider.

[0015] In some embodiments, the second air duct is provided with a second contraction area, and the cross-sectional area of the second contraction area gradually decreases along the air outlet direction of the second air duct.

[0016] In this way, when the second airflow moves along the second air duct, as the space is reduced when passing through the second contraction area, the volume of the second airflow is compressed, and the wind speed of the second airflow is increased, so that the airflow generated by the mixing of the first airflow and the second airflow can be blown further and the blowing coverage is wider.

[0017] In some embodiments, the conical base of the flow guide extends out of the air outlet, and the shell further comprises a flow straightener ring, the flow straightener ring is sleeved on the cylinder, and the flow straightener ring is provided with a flow straightening portion parallel to the conical base, and the flow straightening portion and the conical base jointly form an air outlet flow straightening channel on the air outlet.

[0018] In this way, since the flow straightener ring is provided with a flow straightening portion parallel to the conical base, and the flow straightening portion and the conical base jointly form an air outlet flow straightening channel on the air outlet, the guide direction of the air outlet flow straightening channel coincides with the flow guide path of the flow guide, that is, after the airflow generated by the mixing of the first airflow and the second airflow is ejected from the air outlet, the airflow is biased to the peripheral area of the air outlet working side after being straightened and guided by the air outlet flow straightening channel, so that the airflow can be blown further.

[0019] In some embodiments, the air outlet flow straightening channel is further provided with a wind direction correction ring, and the wind direction correction ring comprises a first ring and a second ring arranged in parallel, the first ring is concentrically arranged in the flow straightener ring, and the second ring is concentrically arranged in the conical base, and the first ring and the second ring are both perpendicular to the air outlet working side.

[0020] In this way, since the first ring and the second ring are both perpendicular to the air outlet working side, the guide direction of the wind direction correction ring formed by the first ring and the second ring is perpendicular to the air outlet working side, so that after the airflow is biased to the peripheral area of the air outlet working side by the guide of the air outlet flow straightening channel, the airflow is then diverged to the middle area of the air outlet working side by the guide of the wind direction correction ring, so that the coverage of the airflow is extended from the peripheral area of the air outlet working side to the middle area of the air outlet working side.

[0021] According to another aspect of the present invention, an indoor temperature control device is also provided, which includes a chassis, a fan, an air suction channel, a heat exchange duct, an air heating element and an air outlet structure; wherein, the fan is arranged in the chassis, the air suction channel is connected to the air suction port of the fan, the air suction channel is extended to the outside of the chassis, the heat exchange duct is connected to the air outlet of the fan, and the heat exchange duct extends from the fan to the first duct and the second duct to provide an air source for the first duct and the second duct; the air heating element is arranged at the entrance of the first duct and the second duct to heat the air entering the first duct and the second duct.

[0022] In this way, when the air in the bathroom needs to be heated, the user starts the indoor temperature control device, the air heating element starts heating, the fan starts to suck in the indoor air through the suction channel, and then blows the air to the air heating element through the heat exchange duct to heat the air, and then enters the air outlet structure from the first air duct and the second air duct. After the heated air is processed by the air outlet structure, it is discharged from the air outlet in a 360° direction, so that every corner of the bathroom is quickly heated up, and the air outlet is uniform.

The terms used in the specification of the application herein are only for the purpose of describing the specific embodiments, and are not intended to limit the application.

[0046] The application will be further described in detail below in conjunction with the drawings.

[0047] Figures 1-8 The air outlet structure of an embodiment of the application is schematically shown as Figures 1-8As shown, the air outlet structure comprises a housing 11, a flow guide 12, a first air duct 13 and a second air duct 14; wherein the housing 11 is provided with an air outlet 112 and an air outlet working side 111 facing the air receiving object, the air outlet 112 extends to the air outlet working side 111, the second air duct 14 is arranged in connection with the flow guide 12, the flow guide path of the flow guide 12 is arranged to radiate and diverge from the second air duct 14 to the peripheral area of the air outlet working side 111 through the air outlet 112; the air outlet direction of the first air duct 13 is arranged to radiate and diverge to the middle area of the air outlet working side 111 through the air outlet 112, the air outlet direction of the first air duct 13 and the flow guide path of the flow guide 12 meet at the air outlet 112, so that when the first air duct 13 and the second air duct 14 simultaneously obtain the air source, the first airflow emitted by the first air duct 13 and the second airflow emitted by the second air duct 14 meet and mix to generate the air supply airflow, and the coverage range of the air supply airflow extends from the peripheral area of the air outlet working side 111 to the middle area of the air outlet working side 111.

[0048] In this way, when the present application is assembled into a specific air supply device (such as a fan, a cooler, an air conditioner, etc.), the first air duct 13 and the second air duct 14 of the present application are connected with the air source, the air outlet working side 111 of the housing 11 is arranged on the air supply panel of the air supply device, the air supply panel faces the air receiving object, that is, the air outlet working side 111 faces the air receiving object, and when the air supply device works, the air source generating unit of the air supply device starts to generate the air source which enters into the first air duct 13 and the second air duct 14 respectively, because the air outlet direction of the first air duct 13 is arranged to radiate and diverge to the middle area of the air outlet working side 111 through the air outlet 112, the first airflow emitted by the first air duct 13 blows to the middle area of the air outlet working side 111, and because the flow guide path of the flow guide 12 is arranged to radiate and diverge to the peripheral area of the air outlet working side 111 through the air outlet 112, the second airflow emitted by the second air duct 14 blows to the peripheral area of the air outlet working side 111 after being guided by the flow guide 12, the first airflow and the second airflow meet and mix to generate the air supply airflow at the air outlet 112, and the first airflow pushes part of the second airflow to be biased to the direction of the middle area of the air outlet working side 111, so that the coverage range of the air supply airflow generated by the meeting and mixing of the first airflow and the second airflow extends from the peripheral area of the air outlet working side 111 to the middle area of the air outlet working side 111, and no matter the air receiving object is directly opposite to the air outlet working side 111 or obliquely opposite to the air outlet working side 111, the air receiving object can receive the air supply airflow, which has the characteristic of wide air outlet coverage range and can uniformly provide temperature regulation effect, thereby bringing convenience to the user.

[0049] In detail, in the embodiment, the air outlet 112 is provided with multiple air supply directions, the flow guide member 12 is provided with multiple flow guide paths, the multiple flow guide paths are provided in one-to-one correspondence with the multiple air supply directions, the air outlet range of the first air duct 13 is set to cover all the flow guide paths of the flow guide member 12, so that the air outlet 112 respectively emits air supply air flow to multiple directions when the first air duct 13 and the second air duct 14 simultaneously obtain air source. In this way, by setting the air outlet 112 to have multiple air supply directions, and providing the flow guide member 12 with multiple flow guide paths in one-to-one correspondence with the air supply directions, the air outlet 112 respectively emits air supply air flow to multiple directions when the first air duct 13 and the second air duct 14 simultaneously obtain air source, which further enhances the air outlet coverage range of the air supply device using the air outlet structure 1.

[0050] In further detail, in the embodiment, the air outlet 112 is provided in a circular ring shape, the multiple air supply directions of the air outlet 112 are respectively arranged to radiate along different radial angles, the flow guide member 12 is provided in a conical shape, the conical bottom seat 121 of the flow guide member 12 is aligned with the middle position of the air outlet 112, the conical top 122 of the flow guide member 12 is aligned with the second air duct 14, so that the inclined direction of the conical surface of the flow guide member 12 extends to the peripheral area of the air outlet working side 111, and the multiple flow guide paths are respectively arranged to extend along the conical surface of the flow guide member 12 at different radial angles. In this way, since the conical top 122 of the flow guide member 12 is aligned with the second air duct 14, and the conical surface of the flow guide member 12 is formed by 360° rotation, when the second air duct 14 obtains air source, the second air flow extends from each radial angle along the conical surface of the flow guide member 12 to the peripheral area of the air outlet working side 111, so that the air outlet 112 has the effect of 360° air outlet, and has the characteristic of uniform air outlet.

[0051] Figure 16 The simulation diagram of the flow path and flow rate of the air flow in the existing air outlet air duct in the Fluent software is shown in the figure, wherein the arrows represent the flow direction of the air flow, the line direction represents the flow path of the air flow, and the line color represents the flow rate of the air flow. The darker the line color, the higher the flow rate. According to the foregoing information, it can be concluded from Figure 16 that 1) the air flow speed distribution at the turning position of the existing air outlet air duct is obviously uneven (the cross section at the turning position is analyzed, and multiple areas with obviously different colors can be seen, which indicates that the air flow speed distribution is uneven); 2) the air flow speed in the existing air outlet air duct does not obviously decrease at the outlet position compared with the air inlet position, and even the air flow speed increases. Since the air flow speed distribution is uneven and the air flow speed is high, it can be seen that the existing air outlet air duct has the problems of uneven air outlet, small air outlet working coverage range, and low comfort experience. Figure 17This is a simulation diagram of the airflow path and flow rate in Fluent software when the air outlet structure is working. The arrow represents the flow direction of the airflow, the direction of the line represents the flow path of the airflow, and the line color represents the flow rate of the airflow. The darker the line color, the higher the flow rate. Combining the above information, from Figure 17 It can be concluded that: 1. Compared with Figure 16 1. There is an existing air outlet duct in the air outlet structure. After the air flow in this air outlet structure is sorted out by this air outlet structure, the air flow velocity distribution is obviously more uniform (from the analysis of the cross section of the air flow, there are no multiple areas with obviously different colors, and the colors of different areas are relatively similar, which shows that the air flow velocity distribution is relatively more uniform); 2. In this air outlet structure, the color of the line at the outlet position is lighter than that at the air inlet position, that is, the air flow velocity in this air outlet structure decreases compared with the air inlet position, making the air flow more gently blown to the human body. Therefore, the air flow distribution after sorting out by this air outlet structure is more dispersed, uniform and gentle, especially it can form an annular air curtain around the human body, providing air supply to the human body more evenly, more warmly and more gently. In addition, the evenly dispersed annular airflow is also conducive to uniform changes in indoor temperature.

[0052] In other embodiments, the specific shape of the air outlet 112 and the number of air outlet directions can be appropriately adjusted according to actual conditions. For example, the air outlet 112 can also be set to a hexagon, and the guide member 12 is correspondingly set to an inverted hexagonal pyramid. The six faces of the hexagonal pyramid are respectively arranged parallel to the six sides of the air outlet 112. Each face of the hexagonal pyramid is used to guide the second air duct 14, that is, the hexagonal pyramid has six guide paths, and the air is correspondingly supplied in six angular directions in the radial direction of the air outlet 112.

[0053] Further in detail, in the present embodiment, the shell 11 comprises a barrel 113, the first air duct 13 and the second air duct 14 are both arranged in the barrel 113, the barrel 113 and the conical base 121 of the flow guide 12 jointly enclose the air outlet 112 in a circular ring shape; the first air duct 13 is arranged in a spiral shape along the inner wall of the barrel 113, the second air duct 14 is arranged at the middle position of the barrel 113, the first air duct 13 is arranged around the second air duct 14, when the first air duct 13 obtains the air source, the first airflow in the first air duct 13 blows towards the air outlet 112 at the same time, the first airflow is spirally blown along the inner wall of the barrel 113, so that the air outlet range of the first air duct 13 covers the air outlet 112 along the inner wall of the barrel 113. In this way, the conical base 121 of the flow guide 12 is nested with the edge of the barrel 113, and an annular gap is formed between the barrel 113 and the conical base 121 of the flow guide 12, that is, the barrel 113 and the conical base 121 of the flow guide 12 jointly enclose the air outlet 112 in a circular ring shape, when the first air duct 13 obtains the air source, the first airflow in the first air duct 13 blows towards the air outlet 112 at the same time, the first airflow is spirally blown along the inner wall of the barrel 113, that is, the movement track of the first airflow covers the entire circumference of the barrel 113, so that the air outlet range of the first air duct 13 covers the air outlet 112 along the inner wall of the barrel 113, since the entire flow guide path of the flow guide 12 passes through the air outlet 112, that is, the air outlet range of the first air duct 13 is arranged to cover the entire flow guide path of the flow guide 12; in addition, the first air duct 13 arranged in a spiral shape guides the first airflow to be spirally blown, so that the first airflow is dispersedly blown 360° outward from the air outlet 112, so that the air volume distribution is more uniform.

[0054] In the present embodiment, the second air duct 14 is arranged in a spiral shape, the spiral directions of the first air duct 13 and the second air duct 14 are arranged to be the same, so that when the second air duct 14 obtains the air source, the second airflow in the second air duct 14 spirally rotates under the guidance of the second air duct 14, after the second airflow passes through the flow guide of the flow guide 12, the second airflow radiates and spreads from the air outlet 112 towards the peripheral area of the air outlet working side 111 at the same time, the second airflow radiates and spreads from each radial angle of the air outlet 112 in a spiral blowing manner, the first airflow and the second airflow are dispersedly blown 360° outward from the air outlet 112 in the same spiral direction, and further the air volume distribution of the air supply airflow generated by the intersection and mixing of the first airflow and the second airflow is more uniform.

[0055] In the embodiment, the first air duct 13 is provided with a first contraction region, the cross-sectional area of which gradually decreases along the air outlet direction of the first air duct 13. In this way, when the first airflow moves along the first air duct 13, the volume of the first airflow is compressed and the wind speed of the first airflow is increased as the space is reduced when passing through the first contraction region, so that the first airflow can be blown further and the blowing coverage is wider.

[0056] In the embodiment, the second air duct 14 is provided with a second contraction region, the cross-sectional area of which gradually decreases along the air outlet direction of the second air duct 14. In this way, when the second airflow moves along the second air duct 14, the volume of the second airflow is compressed and the wind speed of the second airflow is increased as the space is reduced when passing through the second contraction region, so that the airflow generated by the mixing of the first airflow and the second airflow can be blown further and the blowing coverage is wider.

[0057] In the embodiment, the tapered base 121 of the flow guide 12 extends out of the air outlet 112, and the shell 11 further includes a flow straightener ring 114, which is sleeved on the cylinder body 113. The flow straightener ring 114 is provided with a flow straightening portion parallel to the tapered base 121, and the flow straightening portion and the tapered base 121 jointly form an air outlet flow straightening channel 1141 on the air outlet 112. In this way, since the flow straightener ring 114 is provided with a flow straightening portion parallel to the tapered base 121, and the flow straightening portion and the tapered base 121 jointly form an air outlet flow straightening channel 1141 on the air outlet 112, the guide direction of the air outlet flow straightening channel 1141 coincides with the flow guide path of the flow guide 12, that is, after the airflow generated by the mixing of the first airflow and the second airflow is ejected from the air outlet 112, the airflow is biased to the peripheral area of the air outlet working side 111 after being straightened and guided by the air outlet flow straightening channel 1141, so that the airflow can be blown further.

[0058] Further in detail, in the embodiment, the air outlet flow straightening channel 1141 is further provided with a wind direction correction ring 115, which includes a first ring 1151 and a second ring 1152 arranged in parallel. The first ring 1151 is concentrically arranged on the flow straightener ring 114, and the second ring 1152 is concentrically arranged on the tapered base 121. Both the first ring 1151 and the second ring 1152 are perpendicular to the air outlet working side 111. Further in detail, the ratio of the diameter size of the first ring 1151 to the diameter size of the second ring 1152 is X, where 1 < X ≤ 1.5, and preferably, in the embodiment, X is 1.18.

[0059] Thus, since the first ring 1151 and the second ring 1152 are both perpendicular to the air outlet working side 111, the guide direction of the air direction correction ring 115 formed by the first ring 1151 and the second ring 1152 is perpendicular to the air outlet working side 111, so that the air flow is guided by the air outlet rectification channel 1141 to be biased to the peripheral area of the air outlet working side 111, and then guided by the air direction correction ring 115 to be diffused to the middle area of the air outlet working side 111, so that the coverage range of the air flow extends from the peripheral area of the air outlet working side 111 to the middle area of the air outlet working side 111. In detail, in the embodiment, the air direction correction ring 115 also has a mounting positioning function. In the production and assembly, the air direction correction ring 115 is embedded into the plate hole position of the air supply device, which facilitates the alignment and positioning of the air outlet 112 and the hole position of the plate of the air supply device, and improves the production efficiency.

[0060] In detail, in the embodiment, the flow guide piece 12 is provided with a plurality of air guide sides 123, and the plurality of air guide sides 123 are all arranged to extend from the tapered top 122 to the tapered bottom seat 121. In this way, the airflow is scattered and mixed by the plurality of air guide sides 123 after passing through the flow guide piece 12, thereby improving the uniformity of the air volume. In detail, in the embodiment, twenty air guide sides 123 are provided. In other embodiments, the number of air guide sides 123 can also be adjusted according to actual conditions.

In other embodiments, the air outlet structure 1 in the first embodiment can also be applied to scenes such as coolers, kitchen air conditioners, air conditioners, fans, and other scenes requiring air supply.

[0063] In this way, when it is necessary to heat the air in the bathroom, the user starts the present indoor temperature control device, the air heating member 24 starts heating work, the fan 21 starts to suck indoor air through the air suction channel, and then blows the air to the air heating member 24 through the heat exchange air duct to heat the air, and then the heated air enters the air outlet structure 1 from the first air duct 13 and the second air duct 14. After being processed by the air outlet structure 1, the heated air is blown out from the air outlet 112 in a 360° direction, realizing a rotary blowing effect, so that the corners of the bathroom are quickly heated, and the air outlet is uniform.

[0066] Embodiment three

[0067] The difference between the embodiment and the embodiment one is that:

[0068] Figure 14 The air outlet structure 1 of another embodiment of the application is schematically shown;

[0069] As shown in Figure 14 The shell 11 is in the shape of a cylindrical barrel, and the first through cylinder 31 is nested in the shell 11, dividing the internal space of the shell 11 into the first air duct 13 and the second air duct 14. The first through cylinder 31 is coaxially aligned with the conical flow guide 12. The first air duct 13 is formed between the outer periphery of the first through cylinder 31 and the inner wall of the shell 11, and the first air duct 13 is formed in the interior of the first through cylinder 31. In this way, after the first air duct 13 obtains the air source, the movement track of the first air flow is in the shape of a hollow cylinder and extends to the air outlet 112. At the same time, the second air duct 14 obtains the air source, and the second air flow blows to the flow guide 12 in the shape of a solid cylinder. The second air flow extends from various radial angles along the conical surface of the flow guide 12 to the peripheral area of the air outlet working side 111, so that the air outlet 112 has the effect of 360° air outlet. In this process, the movement track of the first air flow covers the entire air outlet 112, that is, the air outlet range of the first air duct 13 is set to cover the entire flow guide path of the flow guide 12.

[0070] Embodiment four

[0071] The difference between the embodiment and the embodiment three is that:

[0072] Figure 15 The air outlet structure 1 of another embodiment of the application is schematically shown;

[0073] As shown in Figure 15As shown, in the present embodiment, the first through-penetration cylinder 31 is further nested with a second through-penetration cylinder 32, which is coaxially arranged with the first through-penetration cylinder 31. In this way, the second through-penetration cylinder 32 further subdivides the space of the second air duct 14 into two separate passages, so that the airflow in the second air duct 14 is divided into two independent air masses blowing towards the flow guide 12. The cylinder wall of the second through-penetration cylinder 32 can slow down or block the lateral movement tendency of the airflow in the air mass (i.e. slow down or block the lateral movement of the airflow towards the direction that is not directly facing the flow guide 12), thereby reducing the probability of generating lateral turbulence.
