[0054] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0055] To achieve the above objectives, the technical solution of this application is as follows:

[0056] See Figures 1-14 As shown, the first aspect of this application provides a waist-mounted fan with uniform airflow, the waist-mounted fan comprising:

[0057] The housing 1 has an air inlet 11, a first air outlet 121, a second air outlet 122 and a third air outlet 123, and the housing 1 is provided with a receiving space 13;

[0058] The first fan assembly 21 is located in the receiving space 13 and is used to blow air toward the first air outlet 121;

[0059] The second fan assembly 22 is located in the receiving space 13 and is used to blow air toward the second air outlet 122;

[0060] The waist-mounted fan also includes a wind-gathering component 3, which is located in the receiving space 13. The wind-gathering component 3 causes at least part of the air generated by the first fan component 21 and the second fan component 22 to be gathered towards the third air outlet 123.

[0061] Compared with the prior art, the beneficial effects of this application are: the wind concentrator 3 concentrates at least part of the air generated by the first fan assembly 21 and the second fan assembly 22 toward the third air outlet 123, thereby increasing the air output intensity of the third air outlet 123 and making the air output of the first air outlet 121, the second air outlet 122 and the third air outlet 123 uniform, meeting the user's usage needs and improving the user's user experience.

[0062] Furthermore, the air-gathering component 3 includes at least four air ducts formed sequentially. The at least four air ducts include a first air duct 31, a second air duct 32, a third air duct 33, and a fourth air duct 34. The air outlet direction of the first air duct 31 corresponds to the first air outlet 121, and the air outlet direction of the fourth air duct 34 corresponds to the second air outlet 122. The second air duct 32 and the third air duct 33 are inclined toward the third air outlet 123 so that the air outlet directions of the second air duct 32 and the third air duct 33 converge toward the third air outlet 123.

[0063] Preferably, the first fan assembly 21 is disposed on one side of the air inlet direction of the first air duct 31 and the second air duct 32, and the second fan assembly 22 is disposed on one side of the air inlet direction of the third air duct 33 and the fourth air duct 34.

[0064] Furthermore, a first inclined plate 321 extending from the second air duct 32 and inclined towards the third air outlet 123 extends from the third air duct 33 and inclined towards the third air outlet 123. By setting the first inclined plate 321 in the second air duct 32, the air outlet direction in the second air duct 32 is changed, causing the air outlet direction of the second air duct 32 to converge towards the third air outlet 123; by setting the second inclined plate 331 in the third air duct 33, the air outlet direction in the third air duct 33 is changed, causing the air outlet direction of the third air duct 33 to converge towards the third air outlet 123, thereby improving the air outlet intensity of the third air outlet 123 and making the air outlets of the first air outlet 121, second air outlet 122, and third air outlet 123 uniform.

[0065] Furthermore, the wind concentrator 3 includes a first wind concentrator 35, a second wind concentrator 36, and a third wind concentrator 37.

[0066] The first wind concentrator 35 is located on one side of the first air outlet 121, and a first wind concentrator space 351 is formed inside the first wind concentrator 35. The first wind concentrator space 351 is connected to the first air duct 31.

[0067] The second wind concentrator 36 is located on one side of the second air outlet 122, and a second wind concentrator space 352 is formed inside the second wind concentrator 36. The second wind concentrator space 352 is connected to the fourth air duct 34.

[0068] The third air-gathering plate 37 is located on one side of the third air outlet 123. A third air-gathering space 353 is formed inside the third air-gathering plate 37. The third air-gathering space 353 is connected to the second air duct 32 and the third air duct 33.

[0069] By setting the first air-concentrating plate 35, the second air-concentrating plate 36 and the third air-concentrating plate 37, the airflow from each air duct is concentrated towards the corresponding air outlet, thereby improving the airflow intensity of each air outlet and enhancing the performance of the waist-mounted fan.

[0070] Furthermore, a wind-gathering groove 373 is formed in the third wind-gathering plate 37. The wind-gathering groove 373 has a first wind-gathering through hole 371 and a second wind-gathering through hole 372. The first wind-gathering through hole 371 is connected to the second air duct 32, and the second wind-gathering through hole 372 is connected to the third air duct 33.

[0071] After air exits from the second air duct 32 and the third air duct 33, the air is gathered into the air-gathering groove 373 through the first air-gathering through-hole 371 and the second air-gathering through-hole 372, ensuring that air exits from the entire air-gathering groove 373. The air then exits through the air-gathering groove 373 to the third air outlet 123, resulting in uniform airflow from the third air outlet 123. Compared to not having an air-gathering groove 373, where the second air duct 32 and the third air duct 33 directly exit air to the third air outlet 123, this would lead to uneven airflow from the third air outlet 123.

[0072] Furthermore, the wind concentrator 3 includes a first column 381, a first cylinder 391, a second column 382, ​​a second cylinder 392, and a third column 383.

The first partition plate 322, the outer wall of the first column 381 and the inner wall of the first cylinder 391 form a first air duct 31.

[0074] The first partition 322, the first inclined plate 321 and the inner wall of the first cylinder 391 form the second air duct 32;

[0075] The second column 382 is disposed inside the second cylinder 392. A second inclined plate 331 extends from the side of the second column 382 near the third column 383. A second partition plate 332 extends from both sides of the second inclined plate 331. The second partition plate 332, the outer wall of the second column 382, ​​and the inner wall of the second cylinder 392 form a fourth air duct 34.

[0076] The second partition 332, the second inclined plate 331, and the inner wall of the second cylinder 392 form the third air duct 33.

[0077] Furthermore, the wind-gathering component 3 also includes a base plate 384, a third wind-gathering plate 37 forming a third cylinder 393, a third column 383 disposed inside the third cylinder 393, a base plate 384 disposed between the third cylinder 393 and the third column 383, a first wind-gathering through hole 371 corresponding to the second air duct 32 and a second wind-gathering through hole 372 corresponding to the third air duct 33, and a wind-gathering groove 373 formed by the inner wall of the base plate 384, the third cylinder 393 and the outer wall of the third column 383.

[0078] Preferably, a first annular channel is formed between the first cylinder 391 and the first column 381, and the first inclined plate 321 divides the first annular channel into a first air duct 31 and a second air duct 32; a second annular channel is formed between the second cylinder 392 and the second column 382, ​​and the second inclined plate 331 divides the second annular channel into a third air duct 33 and a fourth air duct 34.

[0080] The third air-gathering plate 37 is connected to both sides of the first inclined plate 321, and the third air-gathering plate 37 is connected to both sides of the second inclined plate 331, so that the air outlets of the second air duct 32 and the third air duct 33 are gathered in the third air-gathering space 353. The first air-gathering plate 35 is connected to both sides of the first inclined plate 321, so that the air outlet of the first air duct 31 is gathered in the first air-gathering space 351. The second air-gathering plate 36 is connected to both sides of the second inclined plate 331, so that the air outlet of the fourth air duct 34 is gathered in the second air-gathering space 352.
