Abstract

The utility model discloses a double-side fan. The double-side fan comprises a fan seat, a fan head and a support column fixedly connected between the fan seat and the fan head; the fan head comprises a driving device I for output with two shafts and two fan blades which are correspondingly fixed on two output shafts of the driving device I one by one. When the double-side fan is operated, the two fan blades can both blow outwards, so that the problem that an area of 180 degrees behind the fan is unable to be blown is solved, the utilization rate of the fan is increased, and the double-side fan has the effect of energy conservation.

Description

Double-faced fan

Technical field

The utility model relates to a kind of fan, specifically a kind of Double-faced fan.

Background technique

Fan is a kind of household electric appliance of each family's indispensability in summer, and fan both can be used for driving away summer heat, and also can be used for accelerating indoor circulation of air, improved indoor air quality.Fan generally can be divided into ceiling fan, desk fan, hand-held fan etc., general desk fan all only has a side to have flabellum, being limited in scope of blowing, although existing fan can swing, hunting range generally only has 180 degree, 180Du region, fan rear cannot wind-engaging, if by wind to the region of fan, fan must be rotated to 180 ° or re-use another fan and blow, cost is higher, use very loaded down with trivial detailsly, simultaneously the utilization ratio of electric energy is also not high enough.

Model utility content

In view of this, the purpose of this utility model is to overcome defect of the prior art, the fan that provides a kind of the place ahead and rear all can outwards dry.

Double-faced fan of the present utility model, comprise fan base, fan head and be fixedly connected on fan base and fan head between pillar, fan head comprises the drive unit I of twin shaft output and is fixed on one to one two flabellums of two output shafts of drive unit I;

Further, described fan base comprises base, is rotationally connected with chassis and the rotating drive part for driving chassis to rotate of base, rotating drive partly comprises the drive unit II of single shaft output and is fixed on the crank of drive unit II, one end of crank is coaxially fixedly connected with drive unit II, drive unit II is fixed on base and its output shaft and chassis shaft parallel, on chassis, along it, be radially provided with the bar-shaped trough for being slidably matched with crank outer end, wherein, drive unit I is fixed in pillar upper end, and chassis is fixed in lower end;

Further, described base is provided with subbase, and subbase is provided with inner cylindrical surface, and chassis is rotationally connected with base by its external cylindrical surface and coordinating of subbase inner cylindrical surface;

Further, described drive unit I is motor, and drive unit II is synchronous machine;

Further; angle between two output shafts of described drive unit I is 180 degree, and pillar top is fixed with every pressing plate, the axis every pressing plate perpendicular to drive unit I output shaft; on pressing plate, be fixed with safety cover, safety cover covers in the outside of drive unit I and two flabellums.

The beneficial effects of the utility model are: Double-faced fan of the present utility model, fan head comprises the drive unit I of twin shaft output and is fixed on one to one two flabellums of two output shafts of drive unit I.When Double-faced fan is worked, two flabellums all can outwards be dried, and have solved the problem that 180Du region, existing fan rear cannot wind-engaging, and the utilization ratio that improved fan has energy-conservation effect simultaneously.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the utility model is further described:

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the structural representation of fan base.

Embodiment

Fig. 1 is structural representation of the present utility model, the structural representation of Fig. 2 fan base, as shown in the figure, the Double-faced fan of the present embodiment, comprise fan base, fan head and be fixedly connected on fan base and fan head between pillar 5, fan head comprises the drive unit I 4 of twin shaft output and is fixed on one to one two flabellums 1 of 4 two output shafts of drive unit I

In the present embodiment, described fan base comprises base 6, be rotationally connected with chassis 7 and the rotating drive part for driving chassis 7 to rotate of base 6, rotating drive partly comprises the drive unit II 9 of single shaft output and is fixed on the crank 8 of drive unit II 9, one end of crank 8 is coaxially fixedly connected with drive unit II 9, drive unit II 9 is fixed on base 9 and its output shaft and chassis 7 shaft parallels, on chassis 7, along it, be radially provided with the bar-shaped trough for being slidably matched with crank outer end, wherein, drive unit I 4 is fixed in pillar 5 upper ends, chassis 7 is fixed in lower end, when the output shaft of drive unit II 9 rotates, drive crank 8 together to rotate, when reciprocatingly sliding in bar-shaped trough, crank 8 outer ends drive chassis 7 with respect to base 6 reciprocating rotations, because pillar 5 is fixedly connected with fan head, thereby that realizes fan head swings back and forth to increase wind-engaging scope.

In the present embodiment, described base 6 is provided with subbase, and subbase is provided with inner cylindrical surface, and chassis 7 is rotationally connected with base 6 by its external cylindrical surface and coordinating of subbase inner cylindrical surface, coordinates to realize to relatively rotate by cylndrical surface, and rotational resistance is less, and reliability is high.

In the present embodiment, described drive unit I 4 is motor, and drive unit II 9 is synchronous machine, and electric machine structure is simple, it is easy, easy to maintenance to produce, cost is low, the size of synchronous machine invariablenes turning speed and load is irrelevant, can guarantee that each wobble cycle of electric fan head time used is constant.

In the present embodiment; angle between two output shafts of described drive unit I 4 is 180 degree; pillar top is fixed with every pressing plate 2; axis every pressing plate 2 perpendicular to drive unit I 4 output shafts is fixed with safety cover 3 on pressing plate 2, and safety cover 3 covers in the outside of drive unit I 4 and two flabellums 1; every pressing plate 2, can guarantee that 1 air-flow of two flabellums does not interfere with each other; improve air-supply effect, safety cover 3 can make flabellum 1 be isolated from the outside, and guarantees the safety in utilization of fan.

Finally explanation is, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
