Description
Technical field
The utility model relates to a kind of oscillating fan.
Background technique
During the broiling summer, people can select to realize cooling by equipment, such as: air-conditioning, fan, but be that air-conditioning or fan all can only use in appointed area and need consume electric power, flexibility and energy saving are all poor, conveniently, flexibly people then select paper fan, but shake fan when people are tired out and understand that some is tired and frequency is slow, do not reach the effect of cooling, frequency is fast, and arm will turn sour, and this has just become a problem needing solution badly.
Summary of the invention
model utility object:the utility model provides a kind of oscillating fan, its objective is the problem that solution is in the past existing.
technological scheme:the utility model is achieved through the following technical solutions:
A kind of oscillating fan, it is characterized in that: this fan comprises covering of the fan, crank, cam and support, crank is arranged on support by rotating shaft, the root of covering of the fan is stuck on support by temporary fixed card is revolvable, cam is connected linkage with crank, the root of the corresponding covering of the fan in position of cam, makes it can often turn around when rotating and just presses the root of a covering of the fan, thus complete the swing of covering of the fan.
Crank is connected linkage with the driving gear in support, and driving gear engagement driven gear, driven gear is connected linkage with cam, and the diameter of driving gear is greater than driven gear.
The diameter of driving gear and the diameter of driven gear are than being 2:1.
advantage and effect:the utility model provides a kind of oscillating fan, and the phase adopts the elasticity motility of cam accumulation to drive fan frame to swing, and fan frame drives covering of the fan to swing.The utility model has the restriction not by power supply and place, convenient, flexible use, safety, economic dispatch feature.
The utility model material therefor is easily purchased, low price, and preparation process is simple.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is side schematic view;
Fig. 3 is stereogram;
Fig. 4 is structural representation.
embodiment:below in conjunction with accompanying drawing, the utility model is described further:
As shown in Figure 1, the utility model provides a kind of oscillating fan, this fan comprises covering of the fan 1, crank 3, cam 4 and support 5, crank 3 is arranged on support 5 by rotating shaft, the root of covering of the fan 1 is stuck on support 5 by temporary fixed card is revolvable, and cam 4 is connected linkage with crank 3, the root of the corresponding covering of the fan 1 in position of cam 4, make it can often turn around when rotating and just press the root of a covering of the fan 1, thus complete the swing of covering of the fan 1.
Crank 3 is connected linkage with the driving gear in support 5, and driving gear engagement driven gear, driven gear is connected linkage with cam 4, and the diameter of driving gear is greater than driven gear.
The diameter of driving gear and the diameter of driven gear are than being 2:1
When the utility model uses, shake crank 3, crank 3 is with moving cam 4 to rotate, cam 4 drives covering of the fan 1 to swing, and completes labour-saving pectinid process, in addition, because the diameter of driving gear is greater than driven gear, to make it wave more laborsaving, greatly facilitates the process of use.
