Description
Technical field
The present invention relates to a kind of electric fan, particularly a kind of electric fan with Dual-blade.
Background technique
The electric fan great majority of selling on market now only have a flabellum, although it is various that the shape of flabellum can be designed to, the blade of flabellum is also the amount doesn't matter, but the wind ranges that electric fan can provide still can not meet people's demand, for example only need very weak gentle breeze during night rest, and temperature needs very strong wind-force very high daytime, some high-grade electric fans have been introduced microcomputerized control, this type of electric fan is easy to provide high wind, but be but difficult to provide weak gentle breeze, one of reason is that fan blade is more, rotary inertia is larger, allow fan motor acquire a certain degree of difficulty with very slow speed running, if allow motor discontinuous operation, can produce larger noise again, affect people's normal operation activity, also affect sleep quality.
Summary of the invention
The technical problem to be solved in the present invention is: a kind of electric fan with Dual-blade that weak gentle breeze and high wind are provided is provided.
The technological scheme solving the problems of the technologies described above is: a kind of electric fan with Dual-blade, comprise electric fan motor, motor drive shaft, flabellum I and flabellum II, described flabellum I is fixedly mounted on motor drive shaft by bevel gear I, described motor drive shaft is set with motor drive shaft cover outward, described flabellum II is arranged on motor drive shaft by bevel gear II and bearing and puts, at described motor drive shaft, put by axle and bearing the bevel gear III meshing with bevel gear II is installed, described motor axle sleeve is connected with the shell of electric fan motor by elastic device, on the shell of described electric fan motor, the electromagnet that can attract motor axle sleeve is installed, when flabellum II is worked, described bevel gear III and the engagement of bevel gear I.
Further technological scheme of the present invention is: the angle of inclination of described flabellum I upper blade is less than the angle of inclination of flabellum II upper blade.
The true dip direction of described flabellum I upper blade is contrary with the true dip direction of flabellum II upper blade.
Described elastic device comprise position-limited nail be enclosed within the spring on position-limited nail, described position-limited nail is fixedly mounted on the shell of electric fan motor, described spring one end is fixed on the shell of electric fan motor, the other end of this spring is connected with motor axle sleeve.
Described bevel gear III is 2, and these 2 bevel gear III symmetries are arranged on motor drive shaft and put.
The number of blade in described flabellum I is fewer than the blade quantity in flabellum II.
Owing to adopting technique scheme, the present invention's the electric fan with Dual-blade is compared with existing electric fan, has following beneficial effect:
The present invention includes electric fan motor, flabellum I and flabellum II, the angle of inclination of described flabellum I upper blade is less than the angle of inclination of flabellum II upper blade, the true dip direction of described flabellum I upper blade is contrary with the true dip direction of flabellum II upper blade, when only needing weak wind, can only start flabellum I, because the angle of inclination of flabellum I upper blade is less, so its wind-force providing is just more weak, when needs high wind, can start flabellum II, flabellum II is by bevel gear I, the drive of bevel gear III and bevel gear II and rotating, the direction of rotation of flabellum I and flabellum II, and simultaneously to a direction air-supply, the present invention is simple in structure, weak wind and high wind can be provided as required, easy to use, be convenient to extensively promote the use of.
Below, in conjunction with Figure of description and specific embodiment, the technical characteristics of the present invention's the electric fan with Dual-blade is further described.
Accompanying drawing explanation

In above-mentioned accompanying drawing, each label declaration is as follows:
1-electric fan motor, 101-motor drive shaft, 2-flabellum I, 3-flabellum II, 4-bevel gear I, 5-motor axle sleeve, 6-bevel gear II, 7-bevel gear III, 8-electromagnet, 9-position-limited nail, 10-spring, 11-axle.
Embodiment
A kind of electric fan with Dual-blade, comprise electric fan motor 1, motor drive shaft 101, flabellum I 2 and flabellum II 3, the angle of inclination of described flabellum I 2 upper blades is less than the angle of inclination of flabellum II 3 upper blades, the true dip direction of described flabellum I 2 upper blades is contrary with the true dip direction of flabellum II 3 upper blades, and the number of blade in described flabellum I 2 is fewer than the blade quantity in flabellum II 3.Described flabellum I 2 is fixedly mounted on motor drive shaft 101 by bevel gear I 4, outside motor drive shaft 101 between bevel gear I 4 and electric fan motor 1, be set with motor drive shaft cover 5, described flabellum II 3 is arranged on motor axle sleeve 5 by bevel gear II 6 and bearing, on described motor axle sleeve 5, by axle 11 and bearing, 2 bevel gear III 7 that mesh with bevel gear II 6 are installed, these 2 bevel gear III 7 symmetries are arranged on motor axle sleeve 5, when 3 work of flabellum II, described bevel gear III 7 and 4 engagements of bevel gear I.Described motor axle sleeve 5 is connected with the shell of electric fan motor 1 by elastic device, this elastic device comprises position-limited nail 9 and is enclosed within the spring 10 on position-limited nail 9, described position-limited nail 9 is fixedly mounted on the shell of electric fan motor 1, described spring 10 one end are fixed on the shell of electric fan motor 1, and the other end of this spring 10 is connected with motor axle sleeve 5.The electromagnet 8 that can attract motor axle sleeve 5 is installed on the shell of described electric fan motor 1.
In the present embodiment, in described flabellum I 2, there are 2 blades, in described flabellum II 3, have 4 blades.
A kind of conversion as the present embodiment: described motor axle sleeve 5 can be the axle sleeve that one end wall thickness is thicker then offers the cross through hole that bevel gear III 7 can be installed on this wall, then bevel gear III 7 is arranged in this through hole by axle and bearing.
Working procedure of the present invention:
Use (concrete structure as mentioned above) when of the present invention, when only needing weak wind, its band is magnetic to electromagnet 8 energisings, electromagnet 8 adhesive motor axle sleeves 5, detachment dynamic, make bevel gear I 4 and bevel gear III 7 in separated state, now only have flabellum I 2 to open and rotate, because the angle of inclination of flabellum I 2 upper blades is little, and the number of blade is few, so the wind that flabellum I 2 is produced by boasting a little less than, when needs high wind, will open flabellum II 3, even electromagnet 8 power-off, the magnetic of electromagnet 8 is cut off, now spring 10 is just released motor axle sleeve 5 toward the direction of bevel gear I 4, make bevel gear I 4, intermeshing between bevel gear III 7 and bevel gear II 6, because flabellum I 2 is to be fixedly mounted on motor drive shaft 101, so bevel gear I 4 is being rotated under opening state always, bevel gear I 4 is passed to bevel gear III 7 by power, bevel gear III 7 is given to bevel gear II 6 by power, can drive flabellum II 3 to rotate, because the angle of inclination of flabellum II 3 upper blades is larger, and the number of blade is more, so can blow out high wind, flabellum I 2 and flabellum II 3 are all to same direction air-supply.When not needing high wind, only allow electromagnet 8 be with magnetic, now electromagnet 8 just holds motor axle sleeve 5, bevel gear III 7 and bevel gear I 4 are no longer meshed, make the power of bevel gear II 6 disconnect, now flabellum II 3 just stops operating, and also stops blowing out high wind.
