The air outlet slot is formed in the front side of the air outlet hood. The installing part is arranged in the center of the back side of the air outlet hood. The suction assembly comprises a shell, a suction fan arranged in the shell, and an air channel arranged in the shell. One end of the shell is provided with a mesh plate serving as an air channel air inlet, and the other end of the shell is provided with an air channel air outlet. The end, provided with the air channel air outlet, of the shell is fixed in the installing part. The air channel air outlet communicates with the air inlet of the air outlet hood. The safe electric fan is low in noise and high in air volume.

Description

A kind of safe electric fan that can freeze
Technical field
The invention belongs to fan structure design field and in particular to a kind of can refrigeration safe electric fan.
Background technology
Presently commercially available no blade profile Safety far, including base and the annular air mask being arranged on base, in base It is provided with the air draught assembly based on turbine type blower fan；The great advantage of this fan is due to obviating used by traditional electric fan Flabellum, from regardless of whether be respectively provided with fabulous safety to adult or child.But this fan there is also following weak point: In order to avoid huge too fat to move, using the base of small diameter, so limiting the size of turbine type blower fan, enough in order to ensure Air output, the rotating speed of turbine type blower fan is higher, commonly reaches hundreds of to thousands of turn per second, leads to noise very big, and is difficult to eradicate； Further, since the diameter of turbine type blower fan is too little although its rotating speed is very high, but air output still can not be with conventional fan phase Airflow effects are not good for ratio.
Content of the invention
It is an object of the invention to provide the safe electric fan that can freeze that a kind of noise is less and air output is larger.
The technical scheme realizing the object of the invention is: a kind of can refrigeration safe electric fan, include air draught assembly with go out Wind mask；It is characterized in that: also include cold of multiple electricity；Air outlet face cover is provided with fresh air inlet, air-guiding aisle, air-out slot and installation Portion；Fresh air inlet is arranged on the back side of air outlet face cover, and air-out slot is arranged on the front of air outlet face cover, and installation portion is arranged on outlet air surface Cover back side center；Air draught assembly includes housing, setting induced-draught fan in the housing, setting air channel in the housing；Housing One end is provided with the mesh plate as air inlet of air duct, and the other end of housing is provided with duct outlet；Housing is provided with duct outlet One end be fixed in installation portion, duct outlet is connected with air outlet face cover fresh air inlet；Cold of electricity is arranged in air channel and adjacent At mesh plate；The inwall of the housing of air draught assembly is provided with the boss of convex, and boss is provided with centre bore, and this centre bore is away from air draught The aperture of one end of machine is less, and this centre bore is larger close to the aperture of one end of induced-draught fan；Described induced-draught fan is with turbine fan The turbofan of leaf, the shape of the periphery wall of turbine flabellum of turbofan is and described centre bore is adapted to；Housing is provided with air channel It is provided with sealing ring between the inwall of the outer wall of one end of air outlet and air outlet face cover installation portion；Air-out slot is arranged in air outlet face cover Arrange outer wind outlet area circlewise and interior wind outlet area.
The present invention is arranged on the back side center of air outlet face cover air draught assembly, due to air outlet face cover and traditional bladeless fan Base compare, diameter will go up greatly several times, so the present invention from the larger induced-draught fan of flabellum need not too high rotating speed can be Can achieve good airflow effects；Thus having the advantages that noise is less and air output is larger.The present invention and traditional bladeless fan Equally, flabellum is built-in, and outside be can't see, and is also air draught at the mesh plate of aperture very little, air-out from the air-out slot of very little, The finger of child is inserted not enter, so also having preferable safety.
Brief description
Fig. 1 is a kind of structural representation of the present invention；
Fig. 2 is a kind of front view of safe electric fan shown in Fig. 1.
Specific embodiment
(embodiment 1)
The present embodiment is a kind of safe electric fan, as shown in Fig. 1 and Tu, including air draught assembly 1 and air outlet face cover 2；Outlet air surface It is covered with fresh air inlet 21, air-guiding aisle 22 and air-out slot 23；Fresh air inlet is arranged on the back side center of air outlet face cover, and air-out is narrow Hole is arranged on the front of air outlet face cover；Air draught assembly includes housing 11, setting induced-draught fan 12 in the housing, setting in the housing Air channel 13；One end of housing is provided with the mesh plate 14 as air inlet of air duct, and the other end of housing is provided with duct outlet 15； Duct outlet is connected with air outlet face cover fresh air inlet；It is provided with installation portion 24, housing is provided with air channel air-out at air outlet face cover fresh air inlet One end of mouth is fixed in this installation portion,.
Housing is provided between the outer wall of one end of duct outlet and the inwall of air outlet face cover installation portion and is provided with sealing ring 4.
Described induced-draught fan is turbofan or the fan with flabellum.Used by the present embodiment is with turbine flabellum 121 Turbofan, but be also feasible from conventional fan, and can effectively reduce noise.
The present embodiment also includes multiple electricity cold 3；Cold of electricity is arranged in air channel and adjoins at mesh plate；In concrete practice In, also electric cold can be arranged in air outlet face cover and adjoin at duct outlet.
The basic configuration of air-out slot is in arc shaped, leaves spacing between each air-out slot.
Air-out slot arranges outer wind outlet area 25 and interior wind outlet area 26 circlewise in air outlet face cover.
Obviously, the above embodiment of the present invention is only intended to clearly illustrate example of the present invention, and is not right The restriction of embodiments of the present invention.For those of ordinary skill in the field, also may be used on the basis of the above description To make other changes in different forms.There is no need to be exhaustive to all of embodiment.And these Belong to the obvious change that the connotation of the present invention extended out or change and still fall within protection scope of the present invention.
