[0003] Therefore, it is necessary to solve the above technical problems. Summary of the invention

[0004] In view of the above technical problems, the utility model provides a fan with 360-degree air supply, in which the air outlet direction is perpendicular to the axial direction, so as to achieve 360-degree air outlet around the fan and avoid concentrated air blowing to one part of the body; the fan is a centrifugal fan with small size and light weight, small air outlet resistance and thus relatively low noise.

[0005] To achieve the above purpose, the technical solution of the utility model is:

[0006] A fan with 360-degree air supply comprises a motor, a wind wheel and a housing, wherein the wind wheel and the motor are arranged in the housing; the wind wheel has a chassis and a plurality of blades, wherein the plurality of blades are distributed on the chassis in a ring-shaped manner and spaced apart from each other; the circumferential side surface of the housing comprises a plurality of alternate air guide plates, air outlets are formed between the air guide plates, and the outer edges formed by the plurality of blades are opposite to the air outlets.

[0007] The above-mentioned fan with 360-degree air supply takes in air from the axial free end of the blade and discharges air radially and centrifugally. An air duct is formed between the blades and is blown out after being guided by the air guide plate, forming a 360-degree air outlet, thereby avoiding the discomfort caused by concentrated blowing on one part of the body. The fan is a centrifugal fan. Compared with the axial flow fan, it has a smaller size and lighter weight for the same air output. Multiple air outlets are formed by the air guide plate intervals, with small air outlet resistance and thus low noise. It is also power-saving, has a long battery life, and improves battery life.

[0008] In a further optimized solution, the blades are arranged at an inclination, and the air guide plates are arranged at an inclination opposite to the blades.

The inclination direction of the air guide plate 32 faces the air outlet direction between the blades 22. The air guide plate cuts the air outlet in the radial air outlet direction between the blades, and the air outlet formed between the air guide plates is evenly output.

[0042] like Figure 5 As shown, the air guide plate 32 extends along the axial direction of the air inlet of the housing 30, and forms an air guide channel 37 therebetween. The air guide channel enables the fan to form a 360° uniform air outlet.

[0043] like Figure 2 As shown, the angle a between the air guide plate 32 and the blade 22 closest to it is in the range of 80 to 120 degrees, preferably 90 to 100 degrees. Setting the air guide plate and the blade at such an angle is more conducive to smooth air flow.

[0044] like Figure 1 and Figure 3 As shown, the front cover 40 is arranged at one end of the housing 30, which is the air inlet side of the fan, and the front cover 40 is provided with an air inlet 41. The fan with 360-degree air supply takes in air axially from the air inlet of the front cover, and the front cover protects the wind wheel and the user.

[0045] like Figure 1 and Figure 3 As shown, the front cover 40 and the housing 30 are respectively provided with a flange structure 42 to clamp the opening of the clothes to fix the fan. The front cover and the housing respectively clamp the opening of the clothes through their flange structures, thereby increasing the clamping area and ensuring the stability of the fan fixation.
