Ventilation and heat problem, the fan of 360 ° of circle swings are also occurred gradually in the visual field of people.
The patent document of Application No. CN201520123101.8 discloses a kind of oscillating fan, including protecgulum, rear cover and
Fan motor between protecgulum and rear cover, the shaft of fan motor are stretched out outside protecgulum, the fan horse through protecgulum
Up to the driving device that energy driving fan motor circle swing is equipped between rear cover, rotation pendulum is equipped between fan motor and protecgulum
Motivation structure, the rotary swing mechanism includes rotation fixed ring, rotary oscillation ring and connecting rod, before wherein rotation fixed ring is fixed on
It covers, rotation fixed ring is equipped with support base, and rotary oscillation ring is articulated on the support base of rotation fixed ring, one end of connecting rod and wind
Fan the front end connection of motor, the other end and the rotary oscillation ring of connecting rod be hinged, and the articulated position of connecting rod and rotary oscillation ring and
The articulated position of support base and rotary oscillation ring is located at rotary oscillation ring both sides not in the same direction respectively.The utility model utilizes connecting rod
It is hinged with rotary oscillation ring, support base is hinged with rotary oscillation ring, and fan can be realized by this two groups of hinged interactions
360 ° of swing operating is done with respect to protecgulum in motor front end.
The patent adds in rotary swing mechanism in fan cap, and a motor left side is hingedly realized by connecting rod and rotary oscillation ring
Right direction is swung, the support base of rotary oscillation ring and rotation fixed ring carry out it is hinged realize that motor vertical direction is swung, so with
360 ° of circle swings can be carried out by realizing the oscillating fan, but oscillating fan is during rotary oscillation, due to the rotation
The middle rotary oscillation ring and support base of swing mechanism are by articulated connection, and shaft drives interlocking lever that fan motor is driven to be justified
The hinge joint Impact direction of coning motion, rotary oscillation ring and support base changes with time and changes, it is easy to cause support base
Fatigue, service life shorten.
The content of the invention
It is an object of the invention to：Solve the problems, such as that oscillating fan rotary swing mechanism service life is short in the prior art,
There is provided a kind of service life longer swinging electric fan.
The technical solution adopted by the present invention is as follows：

Specific embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to the accompanying drawings and embodiments, it is right
The present invention is further elaborated.If it is to be appreciated that there are term " on ", " under ", "left", "right", " vertical ", " water
It is flat " etc. instructions orientation or position relationship be based on orientation shown in the drawings or position relationship, be for only for ease of and describe this hair
It is bright to have specific orientation, with the device for simplifying description rather than instruction or hint meaning or element with specific orientation
Construction and operation, therefore the terms describing the positional relationship in the drawings are only for illustration, it is impossible to it is interpreted as to this patent
Limitation.
A kind of swinging electric fan, including pedestal 1,1 one end of pedestal is provided with the first driving motor, and the other end of pedestal 1 leads to
It crosses the contact of the second bearing 6 and is provided with fan case 7, fan case 7 can be on the second bearing 6 along the contact point between them
Any direction rotates；One end of fan case 7 is provided with flabellum group 8, and the other end of fan case 7 is eccentric even by oscillating rod 5
It is connected in the first drive shaft 3 of first driving motor.Wherein, oscillating rod 5 may be coupled directly to the bias of the first drive shaft 3
Position can also be connected by adding eccentric wheel outside the first drive shaft 3 and then with oscillating rod 5, but be the need to ensure that,
The intersection point of the line of 5 and first drive shaft 3 of oscillating rod is more efficiently to be in fan case 7, when oscillating rod 5 and first drives
The intersection position of the line of moving axis 3 is exactly the center of fan case 7.
When starting the first driving motor, because 5 bias of oscillating rod is connected in the first drive shaft 3 so that oscillating rod 5 is
Conical motion is set by the contact with the second bearing 6 of fan case 7, and fan case 7 can be on the second bearing 6 along them
Between contact point on any direction rotate so that flabellum group 8 can carry out 360 ° of circle swings, then start fan case
The second motor in 7, electric fan group 8 rotate, and just can realize the swinging rotary air-supply of the electric fan.By the way that pedestal 1 is horizontal
Direction or vertical direction are fixed on ideal point position, just can realize that this electric fan waves the situation of air-supply well.
As preference, 7 bottom of fan case is connected ball, the top of the second bearing 6 is to be fitted with the connected ball
The spherical groove matched somebody with somebody, the connected ball of fan case 7 are caught in the inside of spherical groove of the second bearing 6, which can be in spherical groove
The interior any direction along contact point rotates.When oscillating rod 5 is rotated up, oscillating rod 5 drives 7 rear end of fan case to lift upwards
It rises, connected ball rotates backward, and 7 front end of fan case reduces downwards, i.e., so that flabellum group 8 is dried down；When oscillating rod 5 is turned left
When dynamic, oscillating rod 5 drives 7 right end of fan case to move backward, and connected ball is turned left rotations, the forward movement of 7 left end of fan case, i.e.,
The blowing so that flabellum group 8 is turned right；Likewise, when oscillating rod 5 is downward or turns right, effect is with working as oscillating rod 5
Effect when upwards, turning left is opposite.In this way, it just can realize the swinging rotary air-supply of the electric fan, and fan
Leaf group 8 carries out to have articulation piece during 360 ° of circle swings to be generated tired and the electric fan service life is caused to drop because rotating
It is low.

So that flabellum group 8 is dried down；When oscillating rod 5 turns left, oscillating rod 5 drives 7 right end of fan case to move backward, and connects
Ball is turned left rotation, and 7 left end of fan case moves forward, i.e. the blowing so that flabellum group 8 is turned right；Likewise, when oscillating rod 5 downwards or
When person turns right, effect with when oscillating rod 5 upwards, turn left when effect it is opposite.In this way, just can
It realizes the swinging rotary air-supply of the electric fan, and will not have articulation piece because rotating when flabellum group 8 carries out 360 ° of circle swings
It generates fatigue and causes electric fan service life reduction.
As preference, being further fixedly arranged on the first bearing 2 on the pedestal 1, first drive shaft 3 is set in first
On bearing 2.By the first bearing 2 of setting, the centre of sphere of the axis of the first drive shaft 3 and the connected ball referred to is in same straight line
On.It after setting in this way, can ensure that whole harmony is more preferable, while electric fan is waved more smoothly.
As preference, being additionally provided with connecting rod 4, the first drive shaft 3 is connected with oscillating rod 5 by connecting rod 4.Pass through setting
Connecting rod 4 connects, and avoids because 3 periphery of the first drive shaft is too small, when oscillating rod 5 is connected with 3 bias of the first drive shaft
Cause 8 rotation amplitude of flabellum group too small, the connecting rod 4 so as to select suitable length according to demand connects, and fan is put
Dynamic amplitude is adjusted to suitable size.
As preference, the both ends of the connecting rod 4 are hinged with the first drive shaft 3, oscillating rod 5 respectively, connecting rod 4 is length
Spend adjustable connecting-rod.Set length adjustable by connecting rod 4 and hinged with the first drive shaft 3, oscillating rod 5 respectively so that fan is put
Dynamic amplitude can improve the convenience used without can arbitrarily be adjusted in the case of needing to change connecting rod 4.
As preference, also it is arranged with protection shell outside the fan case 7.This avoid flabellum group 8 in operating
The injury that the external world may be brought in the process.
