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 a safety type double-head electric fan which comprises an air suction assembly and two air outlet masks. Each air outlet mask is provided with a panel and a back plate, the panels are provided with air outlet narrow holes, the positions of the centers of the back plates are provided with installing holes, and air guiding channels are arranged between the panels and the back plates. The air suction assembly comprises a casing, a suction fan arranged in the casing, a first air duct and a second air duct, wherein the first air duct and the second air duct are arranged in the casing. A mesh plate serving as an air inlet hole is arranged in the middle of the casing, the left end of the casing is provided with a first air duct outlet, the right end of the casing is provided with a second air duct outlet, two ends of the casing are arranged in the installing holes of the corresponding back plates, the first air duct outlet is communicated with the air guiding channel of the air outlet mask on the left side, and the second air duct outlet is communicated with the air guiding channel of the air outlet mask on the right side. The safety type double-head electric fan is small in noise and large in air outlet quantity.
Description
technical field [0001] The invention belongs to the technical field of electric fan structure design, and in particular relates to 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 is still not comparable to t...
