Abstract
The utility model relates to an electric fan large-angle swing structure and an electric fan comprising the structure. The swing structure includes a power take-off device, a crank-link mechanism and a gear train, wherein, a crank is connected with an output shaft of the power take-off; the gear train is used for increasing the angular velocity of rotation of a link in the crank-link mechanism, the input end thereof is hinged with the link in the crank-link mechanism, and the output end is connected with a flanged shaft of the fan surface of the electric fan and can rotate along with the rotation of the link, thereby driving the fan surface of the electric fan to swing. The swing structure adopts the gear train to increase the angular velocity of rotation of the link in the crank-link mechanism connected with the power take-off device, so that the fan surface can swing to a large extent, that is, the blowing range of the electric fan is widened, thereby meeting the requirements for the function.
Description
Technical field
The utility model relates to a kind of power transmission arrangment, especially a kind of drive mechanism that is used for the rotation of electric fan covering of the fan.
The utility model also relates to a kind of electric fan, especially a kind of electric fan of shaking the head.
Background technique
For allowing the electric fan blowing range increase, the various electric fans of shaking the head have appearred on the market, this class electric fan of the prior art realizes that covering of the fan function of shaking the head generally carries out transmission by brace and connecting rod framework and reach, but the panning angle of this mode gained is less, generally can be greater than 80 degree, thereby limited to the shake the head blowing range of electric fan of this class, can not be from truly satisfying the requirement of people to this function.
The model utility content
The utility model provides a kind of electric fan wide-angle head oscillating structure at the deficiencies in the prior art, and its interlock by crank-connecting rod and big or small gear train realizes the swing of shaking the head of electric fan covering of the fan wide-angle.
For realizing above technological scheme, the utility model adopts following technological scheme:
A kind of electric fan wide-angle is waved structure, comprising: a power take-off; One connecting rod, wherein crank is connected on the output shaft of power take-off; One gear train, be used for enlarging the angular velocity of rotation of connecting rod connecting rod, the rod hinge connection in its input end and the connecting rod, output terminal then are connected on the flange shaft of electric fan covering of the fan, can rotate along with the rotation of connecting rod, wave thereby drive the electric fan covering of the fan.
Described gear train is made of a gearwheel and a small gear that is mutual outer gearing, and wherein gearwheel is fixedly arranged on electric fan base and hinged with connecting rod off-centre, and small gear then is connected on the flange shaft of electric fan covering of the fan and with transmission of power and gives the electric fan covering of the fan.
Described gearwheel is a sector gear.
Another goal of the invention of the present utility model provides the electric fan that a kind of covering of the fan can be done large angle pendulum.For realizing this goal of the invention, will take following technological scheme:
A kind ofly contain the electric fan that wide-angle is waved structure, described electric fan comprises that above-mentioned electric fan wide-angle waves structure.
According to technological scheme provided by the utility model, can reach following technique effect: 1. the utility model is owing to adopt gear train to enlarge the angular velocity of rotation that is connected in the connecting rod connecting rod on the power plant, thereby the realization covering of the fan can be done significantly swing, has promptly enlarged the blowing range of electric fan; 2. can only in several angle, move reciprocatingly owing to connecting rod, therefore, the gearwheel that connects on it then has only the part teeth to be meshed with small gear, therefore, for saving material and compact this wide-angle is waved structure, gearwheel of the present utility model is a sector gear.
Description of drawings
Fig. 1 is the schematic representation of head oscillating structure provided by the utility model;
Wherein, power take-off 1 crank 2 connecting rods 3 gearwheels 4 small gears 5
Embodiment
Give detailed explanation below with reference to accompanying drawing to head oscillating structure provided by the utility model.
Electric fan wide-angle head oscillating structure provided by the utility model, comprise power take-off 1, the gear train that connecting rod that crank 2 and connecting rod 3 are formed and intermeshing gearwheel 4 and small gear 5 are formed, as shown in Figure 1, the power take-off that the utility model adopted is a synchronous motor, crank 2 is fixedly connected on the output shaft of syncmotor and along with the rotation of this syncmotor and rotates, thereby drive eccentric hinged connecting rod 3 rotations on it, the opposite end of connecting rod 3 then be fixedly arranged on the electric fan base and with to be arranged at the intermeshing gearwheel of small gear 5 on the flange shaft 4 eccentric hinged, so connecting rod 3 can drive gearwheel 4 when doing crankmotion along with crank 2 and small gear 5 back and forth rotates, thereby driving the covering of the fan be connected on the electric fan flange shaft does and waves, hence one can see that, the angular velocity of gearwheel 4 is identical with the angular velocity of connecting rod 3 rotations on the one hand, but the diameter that is the small gear 5 that outer gearing is connected with gearwheel 4 is less, so its angular velocity is then bigger, thereby can realize that the electric fan covering of the fan does on a large scale the air-supply motion, according to experiment that the inventor does as can be known, when head oscillating structure is not provided with gear train amplification connecting rod angular velocity of rotation, the angle that covering of the fan waves generally can be greater than 80 degree, blowing range is less, but, when gear train amplification connecting rod angular velocity of rotation is set in head oscillating structure, the angle that covering of the fan waves can be up to 150 degree, enlarged the blowing range of electric fan greatly, thereby satisfied the requirement of people the electric fan rocking tendency of shaking the head.
In addition, because connecting rod can only be reciprocating in several angle, therefore, 4 of gearwheels in the hinged gear train on it have only the part teeth to mesh with small gear 5, therefore, for the structure that makes head oscillating structure provided by the utility model is more compact, then gearwheel 4 is set to sector gear, and the size of this covering of the fan angle can be determined according to the reciprocating amplitude of connecting rod.
