The included angle between the tilting direction of the slope rotating leaves of the rotating front louvre and the tilting direction of the slope rotating leaves of the inner rotating front louvre is set to 90 degrees, and a speed adjusting knob of the electric fan is started up, so that blades of the electric fan rotates; and then the rotating front louvre is started up, so that the rotating front louvre rotates, and the rotating front louvre drives the inner rotating front louvre to rotate, accordingly, the realistically simulated turbulent natural wind an be obtained in a larger area.
Description
Affiliated technical field
The utility model belongs to household appliance technical field, particularly a kind of electric fan.
Background technique
For electric fan can blow out natural wind, the design of existing many novelties, the scheme of at present widespread usage is the connecting and disconnecting of the circuit formula, stops coming natural wind simulating when just changeing during the electric fan flabellum.Also having a kind of is to utilize the rotation of the preceding blade-rotating of electric fan flabellum to come natural wind simulating.The former shortcoming is when the flabellum rotating speed slows down, and allows the people feel sultry, and is uncomfortable.The latter is the rotation (seeing Fig. 9, Figure 10) that utilizes the inclined-plane of blade-rotating page or leaf sheet, with the shift of wind that electric fan is directly produced by boasting, its objective is to allow the people think that wind is to go up a little while down, comes natural wind simulating with this a little while.Its shortcoming is that the wind of producing by boasting blows to upper body a little while, blows to the lower part of the body a little while, and the position that does not blow to feels sultry, feels under the weather, and does not still have the effect of real natural wind.Real natural wind makes the people feel that comfortable principle is to allow people's whole body wind-engaging, and disorder is arranged slightly, though dynamic, blow continuously on people's body all the time.
Summary of the invention
In order to address the above problem, the purpose of this utility model provides a kind of electric fan of more realistic simulation natural wind, the disorderly natural wind of its wind of producing by boasting simulation, and can blow on people's body by larger area.
The utility model is achieved in that blade-rotating in is set in the blade-rotating of electric fan, between described blade-rotating and the interior blade-rotating gear is set, and the tooth with described gear engagement is set in blade-rotating and the interior blade-rotating; The blade-rotating axle that can rotate is fixedlyed connected with blade-rotating, and interior blade-rotating and blade-rotating axle are the axis hole Spielpassung, and gear and gear hole are the axis hole Spielpassung; Half of the inclined-plane page or leaf sheet sum of blade-rotating or interior blade-rotating is to lopsidedness, and second half opposite side in the opposite direction tilts.
Using method of the present utility model is: the inclined-plane blade-rotating true dip direction of the inclined-plane blade-rotating true dip direction of blade-rotating and interior blade-rotating is set to differ 90 °, start the speed governing button of electric fan, the flabellum of electric fan is rotated, start the blade-rotating button then blade-rotating is rotated, blade-rotating is rotated by blade-rotating in the gear driven; Like this, just can obtain the disorderly natural wind of larger area realistic simulation.
The utility model beneficial effect compared with prior art is:
Because above-mentioned novel electric fan can blow out larger area wind, and the wind that blows out is disorderly, and is dynamic, but blow continuously all the time on people's body, and more approximate natural wind can allow the people feel the nice and cool and comfortable of whole body.

Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
Natural wind makes the people feel that comfortable principle is to allow people's whole body wind-engaging, and disorder is arranged slightly, though dynamic, blow continuously on people's body all the time.The utility model is implemented according to above-mentioned principle: (seeing Fig. 2, Fig. 3), blade-rotating 2 in is set in the blade-rotating 1 of electric fan, a gear 3 is set between described blade-rotating 1 and the interior blade-rotating 2, the tooth 11 with described gear 3 engagements is set in blade-rotating 1 and the interior blade-rotating 2.The blade-rotating axle 31 that can rotate is fixedlyed connected with blade-rotating 1, interior blade-rotating 2 is axis hole Spielpassung (the page or leaf axle 31 that can rotate freely rotates) with blade-rotating axle 31, gear 3 is arranged in the gear hole 32, with gear hole 32 be the axis hole Spielpassung, can freely rotate around gear hole 32.When blade-rotating axle 31 rotates together with blade-rotating 1,, interior blade-rotating 2 is also rotated by the rotation of gear 3.
The inclined-plane page or leaf sheet 17 of tradition blade-rotating is all to the lopsidedness (see figure 10), and half of inclined-plane page or leaf sheet 12 sums of blade-rotating of the present utility model 1 or interior blade-rotating 2 be to lopsidedness, and second half opposite side in the opposite direction tilts, as shown in Figure 8.Using method of the present utility model is: the inclined-plane blade-rotating true dip direction of the inclined-plane blade-rotating true dip direction of blade-rotating 1 and interior blade-rotating 2 is set to differ 90 °, as shown in Figure 5.Start the speed governing button 13 of electric fan, the flabellum of electric fan is rotated, start blade-rotating button 14 then blade-rotating 1 is rotated, blade-rotating 2 was rotated in blade-rotating 1 drove by gear 3.
In state shown in Figure 5, the wind that blade-rotating 1 is produced by boasting is mainly to be to disperse to the left and right forward, and the wind that interior blade-rotating 2 is produced by boasting mainly is to disperse up and down forward.Before the people is in electric fan, will be subjected to up and down the wind of producing by boasting with the centre.Its more traditional electric fan of wind area of producing by boasting is many greatly, disorder (the inclined-plane page or leaf sheet of interior blade-rotating 2 is crossed in the electric fan wind, blows over the inclined-plane page or leaf sheet of blade-rotating 1 again, and collision and deflection have taken place) is but arranged slightly, so simulated disorderly natural wind more realistically.
Blade-rotating 2 turns over an angle in blade-rotating 1 drives, such as, as shown in Figure 6, then the blade-rotating 1 top wind direction forward direction upper left quarter of producing by boasting is dispersed, and the wind of producing by boasting in the bottom towards the previous dynasty lower right part disperse; The wind direction forward direction upper right quarter of producing by boasting in interior blade-rotating 2 tops is dispersed, and the wind direction forward direction lower left quarter of producing by boasting from the bottom is dispersed.By that analogy, blade-rotating 2 turns over any one angle in blade-rotating 1 drives, and all can produce the disturbance wind of dispersing and colliding out.
Like this, just can obtain the disorderly natural wind of larger area realistic simulation.
