However, this kind of fan also has the following disadvantages: in order to avoid bulkiness, a smaller diameter base is used, so the size of the turbo fan is limited. In order to ensure sufficient air output, the speed of the turbo fan is higher, generally reaching every Hundreds to thousands of revolutions per second, resulting in a lot of noise, which is difficult to eradicate; in addition, because the diameter of the turbo fan is too small, although its speed is high, the air output is still not comparable to that of traditional fans, and the blowing effect is not good.

The invention discloses an air suction assembly for a safety type electric fan. The air suction assembly for the safety type electric fan comprises a housing, an air suction fan arranged inside the housing, and an air duct arranged in the housing, wherein one end of the housing is provided with a mesh plate serving as an air duct air inlet, and the other end of the housing is provided with an air duct air outlet. According to the air suction assembly for the safety type electric fan, through an improvement of the air suction assembly, the air suction assembly for the safety type electric fan has the advantages of low noise, large air volume and refrigeration capacity.
Description
technical field [0001] The invention belongs to the technical field of electric fan structure design, and in particular relates to an air suction assembly for a safe electric fan. Background technique [0002] The current commercially available bladeless safety fan includes a base and an annular air outlet mask arranged on the base, and the base is provided with a suction assembly mainly consisting of a turbo fan; the biggest advantage of this fan is that it eliminates the traditional electric The fan blades used by the fan are extremely safe for both adults and children. However, this kind of fan also has the following disadvantages: in order to avoid bulkiness and bloat, the base with a smaller diameter is used, so the size of the turbo fan is limited. Hundreds to thousands of revolutions per second, resulting in a lot of noise, which is difficult to eradicate; in addition, because the diameter of the turbo fan is too small, although its speed is high, the air volume ...
