Description
Technical field
The invention belongs to fan structure design field, be specifically related to a kind of safe double-head electric fan.
Background technique
Commercially available without blade profile Safety far at present, comprise base and be arranged on the annular air outlet face cover on base, in base, be provided with the air draught assembly based on turbo type blower fan; The great advantage of this fan is owing to obviating traditional electrical fan flabellum used, thus no matter all has fabulous Security to adult or child.But this fan also has the following disadvantages: in order to avoid huge too fat to move, adopt the base of small diameter, so limit the size of turbo type blower fan, in order to ensure enough air outputs, the rotating speed of turbo type blower fan is higher, generally reach hundreds of per second to thousands of turns, cause noise very large, and be difficult to eradicate; In addition, because the diameter of turbo type blower fan is too little, although its rotating speed is very high, air output still can not compared with conventional fan, and airflow effects is not good.
Summary of the invention
The object of this invention is to provide a kind of safer reliable safe double-head electric fan.
The technological scheme realizing the object of the invention is: a kind of safe double-head electric fan, comprise air draught assembly and double-end air outlet face cover, double-end air outlet face cover comprises symmetrically arranged two air outlet face cover, each air outlet face cover comprises panel and backboard, panel is provided with air-out slot, the shape of each air-out slot is arc shaped, and backboard center is provided with mounting hole, is provided with air-guiding aisle between panel and backboard; Air draught assembly comprises housing, arrange suction fan in the housing, arrange the first air channel in the housing and the second air channel; The middle part of housing is provided with the mesh plate as intake opening, and the left end of housing is provided with the first ducting outlet, and the right-hand member of housing is provided with the second ducting outlet; The two ends of housing are arranged in the mounting hole of a corresponding backboard, and the first ducting outlet is communicated with the air-guiding aisle of left side air outlet face cover, and the second ducting outlet is communicated with the air-guiding aisle of right side air outlet face cover; Suction fan comprises double end motor and two air draught impellers, and during double end electric machine rotation, air enters from the intake opening of housing central section, after a corresponding air draught impeller, enters into the first air channel and the second air channel.
In such scheme, air-out slot is arranged in ring-type in the front of each air outlet face cover.
The present invention is the same without blade fan with tradition, can flabellum is built-in, and outside be can't see, the mesh plate air draught very little from aperture, air-out from very little air-out slot, and the finger of children is inserted not enter, so have good Security.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present invention.
Fig. 2 is the one application schematic diagram of double-end air outlet face cover shown in Fig. 1.
Embodiment
(embodiment 1)
