Abstract
The invention discloses a safe double-end electric fan with small noises and large air volume. The safe double-end electric fan with small noises and large air volume comprises an induced draft assembly and two air outlet surface shields; each air outlet surface shield comprises a panel and a back plate; an air outlet slot is formed in each panel; a mounting hole is formed in the center of each back plate; an air guide channel is formed between each panel and the corresponding back plate; the induced draft assembly comprises a shell, an induced draft fan, a first air duct and a second air duct; the induced draft fan is arranged in the shell; the first air duct and the second air duct are formed in the shell; a mesh plate used as an air inlet hole is arranged in the middle of the shell; a first air duct outlet is formed in the left end of the shell; a second air duct outlet is formed in the right end of the shell; and the induced draft fan comprises a double-end motor and two induced draft fan wheels. When the double-end motor rotates, air enters from the air inlet hole in the middle of the shell, and enters the first air duct and the second air duct after passing through the corresponding induced draft fan wheels; and two ends of the shell are arranged in the mounting holes of the corresponding back plates, the first air duct outlet communicates with the air guide channel of the air outlet surface shield on the left side of the electric fan, and the second air duct outlet communicates with the air guide channel on the right side of the electric fan. The safe double-end electric fan is small in noises and large in air volume.
Description
The application is the applying date is " on 08 29th, 2013 ", application number is the divisional application that " 2013103815565 ", name are called the application for a patent for invention of " a kind of safe double-head electric fan ".
Technical field
The invention belongs to fan structure design field, be specifically related to the safe double-head electric fan that a kind of noise is less and air output is bigger.
Background technology
Presently commercially available Safety far without blade profile, including base and the annular air face shield being arranged on base, is provided with the air draught assembly based on turbine type blower fan in base；The great advantage of this fan is owing to obviating the flabellum used by tradition electric fan, from regardless of whether adult or child are respectively provided with fabulous safety.But this fan there is also following weak point: in order to avoid huge too fat to move, adopt the base of small diameter, so limiting the size of turbine type blower fan, in order to ensure enough air outputs, the rotating speed of turbine type blower fan is higher, commonly reach hundreds of per second to thousands of turns, cause that noise is very big, and be difficult to eradicate；Further, since the diameter of turbine type blower fan is too little, although its rotating speed is significantly high, but air output still can not compared with conventional fan, and airflow effects is not good.
Summary of the invention
It is an object of the invention to provide the safe double-head electric fan that a kind of noise is less and air output is bigger.
The technical scheme realizing the object of the invention is: the safe double-head electric fan that a kind of noise is less and air output is bigger, including air draught assembly and two air outlet face cover；Each air outlet face cover includes panel and backboard, and panel is provided with air-out slot, and backboard center is provided with installing hole, is provided with air-guiding aisle between panel and backboard；Air draught assembly includes housing, arranges induced-draught fan in the housing, arranges the first air channel in the housing and the second air channel；The middle part of housing is provided with the mesh plate as fresh air inlet, 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；Induced-draught fan includes double end motor and two air draught impellers, and during double end electric machine rotation, air enters from the fresh air inlet of housing central section, after a corresponding air draught impeller, enters in the first air channel and the second air channel；The two ends of housing are arranged in the installing hole of a corresponding backboard, and the first ducting outlet connects with the air-guiding aisle of left side air outlet face cover, and the second ducting outlet connects 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.
The present invention is arranged on the center, the back side of air outlet face cover air draught assembly, owing to air outlet face cover is compared with the base of tradition bladeless fan, diameter wants big several times, so the present invention can select the induced-draught fan that flabellum is bigger, it is not necessary to too high rotating speed can realize good airflow effects；Thus having the advantage that noise is less and air output is bigger.The present invention is the same with tradition bladeless fan, and flabellum is built-in, and outside be can't see, and is also the mesh plate air draught only small from aperture, air-out from only small air-out slot, and the finger of child is inserted not enter, so also having good safety.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present invention.
Detailed description of the invention
(embodiment 1)
The present embodiment is a kind of safe double-head electric fan, as shown in Figure 1, including air draught assembly 1 and two air outlet face cover 2；Each air outlet face cover includes panel 21 and backboard 22, and panel is provided with air-out slot 211, and backboard center is provided with installing hole, is provided with air-guiding aisle 23 between panel and backboard；Air draught assembly includes housing 11, arranges induced-draught fan 12 in the housing, arranges 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 fresh air inlet, 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 installing hole of a corresponding backboard, and the first ducting outlet connects with the air-guiding aisle of left side air outlet face cover, and the second ducting outlet connects 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.
Induced-draught fan includes double end motor 121 and two air draught impellers 122, and during double end electric machine rotation, air enters from the fresh air inlet of housing central section, after a corresponding air draught impeller, enters in the first air channel and the second air channel.
