Abstract
The utility model provides a fan without fan blades, which comprises a base and a fan body arranged on the base, wherein a cylindrical blowing head is arranged on the fan body; and a baffle plate is arranged behind the blowing head to baffle the blowing head. By arranging the baffle plate behind the blowing head, the fan without fan blades provided by the utility model can prevent external air (particularly cold air) from being brought in from the rear part of the blowing head, thereby keeping air supplied by the blowing head at a temperature comfortable for a user, and saving electrical energy.
Description
Technical field
The utility model relates to household electrical appliance technical field, particularly a kind of no flabellum fan.
Background technique
Electric fan is widely used in resident's life, and conventional electric fan is through the running up of motor, and drives fan blade air is cut; Thereby produce the purpose that wind energy reaches cooling, but because conventional electric fan has fan blade, easily dust stratification, be inconvenient to clean; And fan blade produces injury (particularly child) to the people easily; The wind that it produced lets the people feel not to be very comfortable, and the sense of impact is arranged.Thereby blade-free electric fan arises at the historic moment in recent years; Blade-free electric fan comprises base, body, fan electromotor, centrifugation blade and blowing head; Body is connected with a blowing consubstantiality, and blowing head inside all around is hollow air channel, has intake opening below the body; Fan electromotor is installed in the body, and centrifugation blade is connected with fan electromotor is coaxial.Like application number be: 201020614151.3 Chinese patent discloses a kind of no flabellum fan.The blowing head of no flabellum fan is cylindric, and the place ahead of this blowing head cylindraceous is aimed at the people and dried, the rear of this blowing head cylindraceous; Existing technology also provide a kind of can be at the no flabellum fan of blowing hot-air in winter; But because the rear of this blowing head opens wide, so, when the hot blast in this no flabellum fan blows to from the place ahead of this blowing when being blown object; Can bring the lower cold wind of external temperature into from the rear of blowing head; The hot blast that causes producing by boasting is brought into next cold wind reduction temperature by this, makes the people uncomfortable, has wasted electric energy again.
The model utility content
The utility model provides a kind of no flabellum fan that can avoid bringing into from the rear of blowing head ambient air.
To achieve these goals, the utility model provides following technological scheme:
A kind of no flabellum fan comprises base, is arranged on the body on the said base, and said body is provided with columnar blowing head, and the rear of said blowing head is provided with the uncovered baffle plate in rear that is used to block said blowing head.
Preferably, the dismountable rear that is installed in said blowing head of said baffle plate.
Preferably, said baffle plate is installed in the rear open-mouth of said blowing head through buckle or through screw.
Preferably, the uncovered shape in said baffle plate and the rear of said blowing head is identical, and said baffle plate be a circle or oval.
Through implementing above technological scheme; Have following technique effect: the no flabellum fan that the utility model provides is provided with baffle plate through the rear of the head of will drying; Can avoid bringing ambient air (particularly cold wind) into from a blowing rear; Thereby the wind energy that the blowing head is produced by boasting enough keeps temperature, makes the people feel comfortable, has saved electric energy again.
Description of drawings
The plan view of the no flabellum fan that Fig. 1 provides for the utility model embodiment;
The stereogram of the no flabellum fan that Fig. 2 provides for the utility model embodiment.
Embodiment
In order better to understand the technological scheme of the utility model, describe the embodiment that the utility model provides in detail below in conjunction with accompanying drawing.
The utility model embodiment provides a kind of no flabellum fan; As depicted in figs. 1 and 2; Comprise base 101, be arranged on the body 102 on the said base 101; Said body 102 is provided with columnar blowing 103, and the rear of said blowing 103 is provided with baffle plate 104, and it is uncovered that said baffle plate 104 is used to block the rear of said blowing 103.The uncovered shape in this baffle plate 104 and said rear is identical, so that this baffle plate 104 just blocks this rear is uncovered.Preferably, said blowing 103 is a cylindrical shape, and said baffle plate 104 is the cylindrical shape of corresponding said blowing 103, and perhaps, the rear of said blowing 103 is uncovered to be oval or heart-shaped, and said baffle plate 104 be the ellipse of corresponding said blowing 103 or heart-shaped.In other embodiments, also can use the blowing 103 of other shapes, this rear is uncovered also to be other shapes, and said baffle plate 104 also corresponds to this shape, uncovered with the rear of blocking this blowing 103.So that the exhaust outlet of this blowing 103 separates from this rear open-mouth and the external world.
The no flabellum fan that the utility model embodiment provides can be avoided bringing ambient air (particularly cold wind) into from a blowing rear, thereby makes the wind energy of producing by boasting enough keep temperature, makes the people feel comfortable, has saved electric energy again.In other embodiment, this no flabellum fan can also be used for avoiding bring external temperature higher air in summer when use blows out cold wind when fan, thereby makes the wind energy of producing by boasting enough keep temperature, makes the people feel comfortable, has saved electric energy again.
In the above-described embodiments, preferably, said baffle plate 104 removably is installed in the rear of said blowing 103.When not needing this baffle plate 104, this baffle plate 104 of can dismantling easily when needs use, also can be loaded onto this baffle plate 104 easily.More preferably, said baffle plate 104 buckles or be installed in the rear of said blowing 103 through screw, perhaps said baffle plate 104 and said blowing 103 come out for same set of die production, the parts of be connected as a single entity (promptly one-body molded).
More than a kind of no flabellum fan that the utility model embodiment is provided carried out detailed introduction; For one of ordinary skill in the art; Thought according to the utility model embodiment; The part that on embodiment and application area, all can change, in sum, this description should not be construed as the restriction to the utility model.
