[0068] Embodiment 1

[0069] Reference Figures 2 - 9, this embodiment provides a wide - area blowing structure 100, including a main body 10. Taking the end of the main body 10 connected to an external installation base (such as a ceiling, a ceiling or a wall) as the upper end, and the end for air outlet (blowing) as the lower end. The upper and lower ends of the main body 10 are respectively provided with an air inlet end 11 and an air outlet end 13. Among them, the air outlet end 13 is arranged at the outer edge of the lower end of the main body 10 for downward air outlet. The air outlet end 13 includes a first air outlet end 131, a second air outlet end 132 and a third air outlet end 133, and the first air outlet end 131 is located between the second air outlet end 132 and the third air outlet end 133. Among them, a first air outlet 101 is formed between the first air outlet end 131 and the second air outlet end 132, a second air outlet 102 is formed between the first air outlet end 131 and the third air outlet end 133, the first air outlet 101 and the second air outlet 102 converge to form a blowing port 103, and the first air outlet end 131 is recessed and arranged inside the blowing port 103.

[0070] Specifically, the main body 10 includes a first housing 1, a second housing 2, an air outlet ring body 3 and a blowing module 4. Among them, the first housing 1 has a structure with a narrower upper part and a wider lower part. The first housing 1 includes a receiving cavity 12 and a first air inlet 111, and the first air inlet is opened on the air inlet end 11. The receiving cavity 12 is formed by surrounding the first housing 1 and is used for installing the second housing 2, the blowing module 4 and the lighting module 200. The receiving cavity 12 communicates with the first air inlet 111, and the first air outlet end 131 is arranged at the lower end of the first housing 1. In this embodiment, the first air outlet end 131 extends obliquely downward in a direction away from the central axis Z of the first housing 1. The air flow flows into the receiving cavity 12 from the first air inlet 111 at the upper end of the first housing 1, and after being accelerated by the blowing module 4, it flows out to the outside under the guidance of the first air outlet end 131.

[0071] The second housing 2 is installed in the receiving cavity 12. The second housing 2 includes a lamp panel 21 and a base 22. The base 22 is arranged inside the lamp panel 21 for installing the lighting module. In the second housing 2, the second air outlet end 132 extends obliquely downward from the lamp panel 21 in a direction away from the base 22.

[0072] The air outlet ring body 3 is located outside the first housing 1. Specifically, the air outlet ring body 3 is sleeved outside the air outlet end 13. In some embodiments, the air outlet ring body 3 can be integrally formed with the first housing 1 by injection molding; in other embodiments, the air outlet ring body 3 and the first housing 1 can also be a split - type structure, and the two are fixedly connected together by bonding, screwing or ultrasonic welding. In this embodiment, the air outlet ring body 3 and the first housing 1 are an integrally injection - molded structure. The air outlet ring body 3 is provided with a second air inlet 32. Among them, the first air inlet 111 is the main air inlet, and the second air inlet 32 is the auxiliary air inlet. The third air outlet end 133 is arranged at the lower end of the air outlet ring body 3.

[0073] The blowing module 4 is also installed in the accommodation cavity 12 and is located above the second housing 2. The blowing module 4 includes an impeller 41 and a motor 42. Driven by the motor 42, the impeller 41 rotates at a high speed, and at the same time, accelerates the air flow entering the accommodation cavity 12 and blows it out to the outside.

[0074] Further referring to Figure 5 , the outer first air outlet end 131 surrounds the inner second air outlet end 132 to form a first air outlet 101; and the third air outlet end 133 located outside the first air outlet end 131 surrounds the first air outlet end 131 to form a second air outlet 102, and the first air outlet 101 and the second air outlet 102 converge to form a blowing port 103. The first air outlet end 131 located between the third air outlet end 133 and the second air outlet end 132 is recessed inward and is located inside the blowing port 103.

[0075] In the wide-area blowing structure 100 of the present embodiment, the plane where the third air outlet end 133 is located is used as the air outlet surface 31, the second air outlet end 132 is flush with the air outlet surface 31, and the first air outlet end 131 is located above the air outlet surface 31.

[0076] In the wide-area blowing structure 100, the air flow enters the accommodation cavity 12 from the first air inlet 111 respectively. After being accelerated by the blowing module 4, it flows out to the outside through the first air outlet 101 and the blowing port 103. Since the first air outlet end 131 and the second air outlet end 132 are respectively formed by extending obliquely downward from the lower end of the first housing 1 and the lower end of the lamp panel 21, both the first air outlet end 131 and the second air outlet end 132 have a guiding function, which can make the air flow blow obliquely downward on the outside and avoid blowing directly downward. In addition, another part of the air flow enters the air outlet channel surrounded by the air outlet ring body 3 and the first housing 1 from the second air inlet 32, and flows out to the outside through the second air outlet 102 and the blowing port 103. In the blowing port 103, the air flow located below the first air outlet 101 flows out at a faster speed due to being accelerated by the impeller 41, and the outflow speed of the air flow located below the second air outlet 102 is slower. Therefore, a negative pressure will be formed in a local area of the blowing port 103, so that air flows with different speeds are mixed to form a turbulent flow, which can be diffused to the outside of the third air outlet end 133, thereby expanding the blowing range.

[0077] In order to make the air flow flowing out through the blowing port 103 have a greater outflow speed and can also blow obliquely downward to a greater extent to the outside, the relative positions of the first air outlet end 131, the second air outlet end 132 and the third air outlet end 133 are optimized in this embodiment. As Figure 4 shown, the first housing 1 has a central axis Z. It can be understood that the first housing 1 is a rotationally symmetric body formed by surrounding the central axis Z as the axis of symmetry.

[0078] Combined with reference to Figures 4 - 6, the direction parallel to the central axis Z is the first direction L1. In this embodiment, the first direction L1 is the vertical direction. In the first direction L1, the distance between the first air outlet end 131 and the air outlet surface 31 is H, and the value range of H is 3 mm ≤ H ≤ 8 mm. That is, the height difference between the first air outlet end 131 and the third air outlet end 133 (the second air outlet end 132) is between 3 - 8 mm. The first air outlet 101 and the second air outlet 102 are bounded by the first air outlet end 131, and the first air outlet end 131 is recessed inward, so that the airflows flowing out from the first air outlet 101 and the second air outlet 102 converge in the air outlet 103. The airflow below the first air outlet 101 flows out of the air outlet 103 faster. At this time, the airflow flowing out from the second air outlet 102 can be supplemented, thereby forming a turbulent flow, and the airflow flowing directly downward will be effectively reduced.

[0079] Further, the direction parallel to the air outlet surface 31 is the second direction L2. In this embodiment, the second direction L2 is the horizontal direction. In the second direction L2, the distance between the inner side wall of the first air outlet end 131 and the outer side wall of the second air outlet end 132 is W1, and the distance between the outer side wall of the first air outlet end 131 and the inner side wall of the third air outlet end 133 is W2. There is a relational expression between W1 and W2: W1 > W2. By adjusting W1, the initial air velocity of the first air outlet 101 and the air outlet 103 can be controlled. By adjusting W2, the air outlet angle can be controlled to guide the airflow to flow obliquely downward to the outside.

[0080] In some embodiments, a lamp cover 5 is installed on the base 22 of the second housing 2, which is used to diffuse the light emitted by the lighting module 200 and protect the lighting module 200. The lamp cover 5 includes a first light-emitting part 51 and a second light-emitting part 52. Among them, the first light-emitting part 51 has an annular structure, and the second light-emitting part 52 bulges from the first light-emitting part 51 in a direction away from the base 22. In the second direction L2, the distance between the inner side wall of the second air outlet end 132 and the outer side wall of the first light-emitting part 51 is W3. Among them, W3 > W1, and the value range of W3 is W3 > 10 mm. In the above value range, the air outlet angle can be prevented from shifting inward, and while meeting the air volume, the air is blown to the outside to expand the blowing range.

[0081] Further, in any cross-section passing through the central axis Z, such as Figure 5As shown, a straight line B parallel to the air outlet surface 31 intersects the outer side wall of the first housing 1 with an arc-shaped structure at point P and intersects the outer side wall of the second housing 2 with an arc-shaped structure at point Q. First tangent P1 and second tangent Q1 are respectively made through point P and point Q. There is a first included angle α between the first tangent P1 and the horizontal end face 31, and a second included angle β between the second tangent Q1 and the horizontal end face 31; wherein, α > β. Through the setting of the above first included angle α and second included angle β, when ensuring that the first air outlet 101 is an annular air outlet with a narrow upper part and a wide lower part, the outflow speed of the air flow can be large and the air flow can flow outwards.

[0082] Reference Figure 7 , the second housing 2 is provided with a rotating seat 23, and the impeller 41 of the blowing module 4 is arranged above the rotating seat 23, and the impeller 41 is drivingly connected to the motor 42. Wherein, the impeller 41 extends towards the direction away from the air outlet 103 to form a first convex edge 411, and the first convex edge 411 has an annular structure; correspondingly, the first housing 1 is arc-shaped and bent towards the accommodating cavity 12 at the air inlet end 11 to form a second convex edge 112, and the second convex edge 112 also has an annular structure. The first convex edge 411 is arranged around the outer periphery of the second convex edge 112. On the basis of this structure, the air flow flows into the accommodating cavity 12 from the first air inlet 111 and all flows into the blade air duct of the impeller 41. Driven by the motor 42, the impeller rotates at an accelerated speed and makes the air flow flow outwards. Outside the first housing 1, part of the air flow also flows into the air duct formed by the air outlet ring body 3 and the air outlet end 13 from the second air inlet 32, and flows out to the outside through the second air outlet 102 and the blowing port 103.

[0083] In some embodiments, a face cover 6 is arranged above the air outlet ring body 3 of the wide-area blowing structure 100. Specifically, the face cover 6 is located outside the first housing 1, and the face cover 6 is fixedly connected to the air outlet ring body 3. The face cover 6 is an exterior decorative part, and an air inlet groove 61 communicating with the second air inlet 32 is opened on it. Part of the air flow flows into the second air inlet 32 from the air inlet groove 61 and then flows out from the second air outlet 102.

[0084] In the wide-area blowing structure of this embodiment, by optimizing the relative positions of multiple air outlet ends, the first air outlet end is set to be higher than the air outlet surface and is recessed towards the inside relative to the second air outlet end and the third air outlet end. The air flow is accelerated by the impeller and flows out from the first air outlet and the blowing port, and a local negative pressure is formed at the blowing port; part of the air flow flows into the blowing port through the second air outlet for supplementation, so that the overall air output is large; since both the first air outlet end and the second air outlet end extend obliquely downwards in a direction away from the central axis, the air flow can be guided to flow outwards, so that the air flow effectively diffuses outwards, the blowing area is wide, while expanding the air outlet range, the air flow can be prevented from gathering towards the inside, avoiding the situation of "blowing the vegetables but not the people" caused by blowing only directly downwards.

[0085] Embodiment 2

[0086] Figure 10 Schematic diagram of the air blowing of the wide-area air blowing structure of this embodiment. Based on Figures 2 - 9 and referring to Figure 10 , a first air outlet cavity 110 is formed between the first housing 1 and the second housing 2. The first air outlet cavity 110 is located in the accommodation cavity 12 and is communicated with the first air inlet 111 and the first air outlet 101. Moreover, from the first air inlet 111 to the first air outlet 101, the cavity size of the first air outlet cavity 110 gradually becomes smaller. In this way, the first part of the air flow M passing through the first air outlet cavity 110 will be compressed at high speed and flow out from the first air outlet 101 to the air outlet 103, and finally flow out to the outside.

[0087] The air outlet ring body 3 is sleeved on the outside of the air outlet end 11 of the first housing 1. Specifically, the air outlet ring body 3 is inclined on the outside of the first housing 1, and the lower end of the air outlet ring body 3 is closer to the outer wall of the first housing 1 than the upper end. And a second air outlet cavity 120 is formed between the air outlet ring body 3 and the first housing 1. The second air outlet cavity 120 is communicated with the second air inlet 32 and the second air outlet 102; from the second air inlet 32 to the second air outlet 102, the cavity size of the second air outlet cavity 120 gradually becomes smaller.

[0088] As Figure 10 shown, in the wide-area air blowing structure 100, when the impeller 41 rotates, the first part of the air flow M flows into the accommodation cavity 12 from the first air inlet 111. The air flow in the first air outlet cavity 110 will be driven by the impeller and then compressed at high speed and flow out from the first air outlet 101 to the air outlet 103, and finally flow out to the outside. The second part of the air flow N flows into the second air outlet cavity 120 from the second air inlet 32. In the air outlet 103, since the air flow below the first air outlet 102 flows out to the outside at a relatively high speed, a negative pressure is formed. In this way, the air flow flowing from the second air outlet 102 will be supplemented, and the overall air flow in the air outlet 103 will form a turbulent flow, which is beneficial to flowing out towards the lower outside, with an angle expansion, avoiding direct blowing directly below.

[0089] Figure 11 Overall air flow simulation diagram of the wide-area air blowing structure of this embodiment. As Figure 11 shown, when blowing air downward through the air outlet, the angle expands outward, and the wind speed in the central area is relatively low.

[0090] Figure 12 Cross-sectional wind speed distribution simulation diagram at a position 1.5 meters directly below the wide-area air blowing structure of this embodiment. As Figure 12 shown, the air flow velocity and direction in the air outlet cavity are stable, the initial velocity at the air outlet is the largest, and the air outlet angle is slightly outward. There is no obvious air flow on the inner side being diverted by the lampshade.
