Description
Technical field
The relevant a kind of electric fan of the utility model is meant a kind of hand-held electric fan that can conveniently hand and not hinder inlet air and air-out especially.
Background technique
Before and after at present the wind inlet of fan is in exhaust outlet on the same straight line, therefore if fan head (comprising motor and flabellum part) can stop inlet air and air-out in directly hand held, therefore use is inconvenient.Though one handle can be installed on fan, this handle is two independent parts with the fan head, therefore can cause present portable fan volume excessive, and inconvenience is placed, and the shape-designing of fan head also loses flexibility.Because the setting of the parallel inlet air air-out of present portable fan makes existing portable fan be not easy to erect and blows in the plane (exhaust outlet upwards), also is not easy to hang and blows earthward on the wall.
The model utility content
In view of this, the main purpose of the utility model is to provide a kind of hand-held electric fan that can conveniently hand and not hinder inlet air and air-out.
For achieving the above object; The utility model provides a kind of hand-held electric fan, and it includes a housing, and this housing one end top side is provided with wind inlet up; Housing the other end side is provided with exhaust outlet; Be equiped with flabellum in this wind inlet, be provided with in this housing and can drive the motor that flabellum rotates, be 20 ~ 160 degree angles between this wind inlet wind direction and the exhaust outlet wind direction.
Said wind inlet place is provided with the protecting wire net that is used to protect said flabellum, and said exhaust outlet place is provided with the air-out mouth mask.
Said wind inlet place is provided with the inlet air flap, this inlet air flap bottom and front opening, and this inlet air flap bottom opening place is installed on said wind inlet place.
Preferably, said inlet air flap is downward-sloping to the back-end by front end.
Preferably, said inlet air flap is downward-sloping by the rear end forward end.
Preferably, said inlet air flap front end is concordant with the rear end.
Said wind inlet tops is provided with capable of opening and closing solar panels.
The power supply of promising said motor power supply is installed in the said hand-held electric fan, and this power supply is at least a in rechargable battery, dryelement cell, solar cell, USB power supply interface, automobile cigarette lighter power supply and the power of alterating and direct current transformer.
Said flabellum is centrifugal flabellum or Directivity formula flabellum.
Preferably, said hand-held electric fan is provided with anion generator and/or heating line.
The hand-held electric fan of the utility model can conveniently be handed in use and can not block wind inlet and exhaust outlet, and is easy to use.

Embodiment
For ease of structure of the utility model and the effect that reaches are had further understanding, combine accompanying drawing to develop simultaneously the preferred embodiment detailed description as follows at present.
Like Fig. 1 and shown in Figure 2; The hand-held electric fan of the utility model comprises a housing 1, and these housing 1 one end top sides are provided with wind inlet 10, and housing 1 the other end side is provided with exhaust outlet 11; Be equiped with the flabellum (not shown) in this wind inlet 10; This flabellum can be centrifugal or the Directivity formula, and flabellum in the utility model and built-in motor are in housing 1, and wind inlet 10 places are provided with the protecting wire net 12 that is used to protect flabellum; Exhaust outlet 11 places can be provided with air-out mouth mask (not shown), get in the housing to stop big foreign matter.Can be at least a in rechargable battery, dryelement cell, solar cell, USB power supply interface, automobile cigarette lighter power supply and the power of alterating and direct current transformer for the power supply of motor power supply in the utility model.By visible among Fig. 1, wind inlet 10 up, exhaust outlet 11 is towards right; The fan hub of flabellum forms the passage of wind, and wind is got in the housing 1 by wind inlet 10 from the top down, and the air channel in housing 1 is blown out by exhaust outlet 11; Therefore the wind direction of wind inlet 10 is not parallel with the wind direction of exhaust outlet 11, neither front and back point-blank, but be 20 ~ 160 degree angles; Therefore the user can directly hold housing 1 both sides of fan with hand, and can not block wind inlet 10 and exhaust outlet 11, makes the smooth and easy turnover of wind.Exhaust outlet 11 places in the utility model also can uneasiness take on air port cover (not shown), to reduce the resistance to wind.
Wind inlet 10 places of the hand-held electric fan of the utility model can be provided with inlet air flap 14; Extremely shown in Figure 5 like Fig. 3; This inlet air flap 14 bottoms and front opening; This inlet air flap 14 is by front end downward-sloping to the back-end (as shown in Figure 3), and perhaps inlet air flap 14 is tilted to descend (as shown in Figure 5) by the rear end forward end, or front end concordant with the rear end (as shown in Figure 4).As shown in Figure 6, inlet air flap 14 bottom opening places are installed on wind inlet 10 places, can be so that the wind direction of wind inlet 10 rotation 20 ~ 160 degree angles; Make the inlet air direction parallel like this with air-out direction; Therefore when using electric fan, the user can also directly hand inlet air flap 14 except can handing housing 1 both sides; And can not stop air intake and air-out, use convenient.As shown in Figure 7; Inlet air flap 14 tops of the utility model also can be provided with capable of opening and closing solar panels 15; These solar panels 15 are electrically connected the motor of fan, and these solar panels 15 can paste to inlet air flap 14 tops, in use can be cocked; Make solar panels 15 subtend sunlight with store electrical energy, be the fan power supply.
The hand-held electric fan of the utility model can be provided with anion generator, also can be provided with the heating line, so that can blow out hot blast.
The above is merely the preferred embodiment of the utility model, is not the protection domain that is used to limit the utility model.
