Description

A kind of safe double-head electric fan
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 the less and safe double-head electric fan that air output is larger of a kind of noise.
The technological scheme realizing the object of the invention is: a kind of safe double-head electric fan, comprises air draught assembly and two air outlet face cover; Each air outlet face cover comprises panel and backboard, and panel is provided with air-out slot, 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; 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; 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.
The present invention is arranged on the center, the back side of air outlet face cover air draught assembly, due to air outlet face cover with tradition without blade fan base compared with, diameter wants large several times, so the present invention can select the suction fan that flabellum is larger, can realize good airflow effects without the need to too high rotating speed; Thus there is the less and advantage that air output is larger of noise.The present invention is the same without blade fan with tradition, and flabellum is built-in, and outside be can't see, and is also 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 also have good Security.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present invention.
Embodiment
(embodiment 1)
The present embodiment is a kind of safe double-head electric fan, as shown in Figure 1, comprises air draught assembly 1 and two air outlet face cover 2; Each air outlet face cover comprises panel 21 and backboard 22, and panel is provided with air-out slot 211, and backboard center is provided with mounting hole, is provided with air-guiding aisle 23 between panel and backboard; Air draught assembly comprises housing 11, setting suction fan 12 in the housing, setting the first air channel 13 and the second air channel 14 in the housing; The middle part of housing is provided with the mesh plate 15 as intake opening, and the left end of housing is provided with the first ducting outlet 131, and the right-hand member of housing is provided with the second ducting outlet 141; 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.
The shape of each air-out slot is arc shaped, and is arranged in ring-type in the front of each air outlet face cover.
Suction fan comprises double end motor 121 and two air draught impellers 122, 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.
The present embodiment also comprises electricity cold 3, and cold of electricity is arranged in the housing, between two backboards and adjacent mesh plate arrange.
Obviously, the above embodiment of the present invention is only for example of the present invention is clearly described, and is not the restriction to embodiments of the present invention.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all mode of executions.And these belong to connotation of the present invention the apparent change of extending out or variation still belong to protection scope of the present invention.
