Abstract
The invention discloses a safety electric fan. The safety electric fan comprises an induced draft component and an air-out shield, wherein the air-out shield is provided with an air intake hole, an air guiding channel, air outlet slots and a mounting part; the air intake hole is formed in the back of the air-out shield; the air outlet slots are formed in the front side of the air-outlet shield; the mounting part is arranged in the center of the back of the air-outlet shield; the induced draft component comprises a housing, a suction fan arranged in the housing and an air duct formed in the housing; a mesh plate serving as the air inlet of the air duct is arranged at one end of the housing, and the air outlet of the air duct is formed in the other end of the housing; and the end, with the air outlet of the air duct, of the housing is fixed in the mounting part, and the air outlet of the air duct communicates with the air inlet of the air-outlet shield. The safety electric fan is small in noise and large in air volume.
Description
Technical field
The invention belongs to fan structure design field is and in particular to a kind of 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 security 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 a kind of noise is less and air output is larger.
The technical scheme realizing the object of the invention is：A kind of safe electric fan, including air draught assembly and air outlet face cover；Its
It is characterised by：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
It is arranged on the back side of air outlet face cover, air-out slot is arranged on the front of air outlet face cover, and installation portion is arranged in the air outlet face cover back side
At the heart；Air draught assembly includes housing, setting induced-draught fan in the housing, setting air channel in the housing；One end of housing is provided with
As the mesh plate of air inlet of air duct, the other end of housing is provided with duct outlet；One end that housing is provided with duct outlet is solid
It is scheduled in installation portion, duct outlet is connected with air outlet face cover fresh air inlet；Cold of electricity is arranged in air channel and adjoins 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 one end of induced-draught fan
Aperture less, this centre bore is larger close to the aperture of one end of induced-draught fan；Described induced-draught fan is the turbine with turbine flabellum
Blower fan, the shape of the periphery wall of turbine flabellum of turbofan is and described centre bore is adapted to；The basic configuration of air-out slot is in
Arc shaped, leaves spacing between each air-out slot.
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 children is inserted not enter, so also having preferable security.
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
