UTILITY MODEL CONTENT

[0004] The utility model discloses a blowing fan frame body inner air outlet flared structure to solve the problem in the background art.

[0005] To achieve the above object, the utility model provides the following technical scheme:

[0006] The utility model discloses a blowing fan frame body inner air outlet flared structure, including upper cover, base and fan blade group, the lower end of upper cover and base is formed with the air outlet of gradually expanding type after cooperation, the base includes side elevation and bottom plate, be equipped with tongue portion on the side elevation, the bottom plate includes air collecting area and air outlet area.

[0007] Further, the side elevation, the bottom plate and the tongue portion are integrally formed.

[0008] Further, the air collecting area and the air outlet area have an inclination angle, and the thickness dimension of the air outlet area gradually decreases outward.

[0009] Further, the side elevation upper end is equipped with the clamping groove, and the upper cover is embedded in the clamping groove.

[0010] Further, the tongue portion is provided with an assembly groove, and a lock hole is arranged in the assembly groove and penetrates the assembly groove.

[0011] Further, the upper cover side edge is provided with a buckle matched with the side elevation.

[0012] Beneficial effect: a blowing fan frame body inner air outlet flared structure adopts the structure that the bottom plate of the base gradually thins in the air outlet direction, the structure that the vertical direction height of the air outlet remains unchanged, achieves the flared effect, replaces the equal-thickness structure of the frame body bottom plate in the prior art, realizes the purpose of increasing the heat dissipation area and the air outlet volume.

[0018] The following is the specific embodiment of the utility model and combining with the drawings, the technical scheme of the utility model is further described, but the utility model is not limited to these embodiments. EMBODIMENT

[0019] As Figs. 1-3 Indicated, a blast fan frame air outlet flared structure, including upper cover 1, base 2 and fan blade group 3, upper cover 1 and base 2 cooperate after its lower end is formed with gradually expanding air outlet 4, base 2 includes side elevation 21 and bottom plate 22, side elevation 21 is equipped with tongue 23, bottom plate 22 includes wind collecting area 221 and air outlet area 222.

[0020] Wind collecting area 221 and air outlet area 222 between have inclination angle, air outlet area 222 thickness size gradually becomes small outward, base 2 is reduced through air outlet area 222 in the air outlet direction, reaches flared effect, heat dissipation area increases, wind volume increases.

[0021] Side elevation 21 upper end is equipped with clamping groove 211, upper cover 1 is embedded in clamping groove 211, the vertical height of clamping groove 211 is consistent with the thickness of upper cover 1, can realize that upper cover 1 is completely embedded in base 2, guarantees the appearance of blast fan whole;Tongue 23 is equipped with assembly groove 231, lock hole 232 is formed in assembly groove 231, lock hole 232 penetrates assembly groove 231, upper cover 1 side is equipped with the buckle 11 matched with side elevation 21, when assembling, lock into screw in lock hole 232, and by buckle 11 is buckled into the limiting block of both sides of side elevation 21, realizes locking connection between upper cover 1 and base 2.

[0022] Under the condition of voltage setting 5V, speed setting 13000RPM, the frame air outlet flared design mechanism, same speed test data shows that, wind volume effectively increases 5.2%, noise effectively reduces 2dBA.

[0023] The base 2 is provided with the bottom plate 22 gradually thinned in the direction of the air outlet, and the structure for keeping the height of the air outlet in the vertical direction unchanged, so that the air outlet is expanded, the heat dissipation area is increased, and the air volume is increased.

[0024] The following table is a schematic table of air volume noise test data:
