Description
[technical field]
The utility model relates to a kind of electric fan, particularly a kind of New Type of Fan.
[background technique]
Electric fan is conventional family expenses and commercial industrial electrical equipment, and utilization rate is very high.Not only family uses, and all trades and professions can be used.Conventional electric fan has vertical fan, desk fan, wall fan, ceiling fan and ground fan etc., and electric fan helps people to solve the sultry hardship of high temperature in hot summer.But the major axis of the blade of conventional electric fan is straight line, and wind narrow range, blowing area is little, be difficult to adapt to the many distributions of people and loose situation.Although there is oscillating function, when electric fan oscillating road, another side just imperceptible cool breeze, can not be subject to pectinid by sense of continuity, allows people have the nice and cool sensation do not continued.
[model utility content]
For the deficiency that prior art exists, it is simple that the utility model provides structure, and cost is low, a kind of New Type of Fan easy to use, and it, by improving the structural design of existing electric fan blade and protective housing, makes this novel product can increase pectinid face.
In order to solve above-mentioned Problems existing, the utility model have employed following technical proposal:
A kind of New Type of Fan, comprise flabellum and fan electromotor, fan electromotor is arranged on motor cabinet, and flabellum is by fan electromotor driven rotary, it is characterized in that: described flabellum blade is along long axis direction camber, and flabellum blade outer end arc valgus angle scope is between 5 ° to 40 °.
A kind of New Type of Fan described above, is characterized in that: described flabellum blade has 5 ° of length of blade to 40 ° of arc valgus angle account for whole flabellum blade axial length 1/1 to four/8th.It is larger that the length of blade of arc valgus angle accounts for whole flabellum blade axial length, then pectinid face is larger.
A kind of New Type of Fan described above, it is characterized in that: described flabellum blade is placed in a protective housing, protective housing comprises front shroud, back cover and crimp, front shroud connecting end edge is drawn close formation one to central direction extension and is enclosed the connection edge that width is front shroud diameter 1/5th, and front shroud, back cover are connected to form a complete protective housing by crimp.
The beneficial effects of the utility model are:
1, by flabellum blade along long axis direction camber, thus make fan demeanour to enclose and blowing area greatly expands; Flabellum blade outer end arc valgus angle scope is between 5 ° to 40 °, and than existing common flabellum, its front space wind area increases by 80 ﹪-90 ﹪, thus people can be allowed to continue comprehensively to experience cool breeze.
2, the utility model is applicable to vertical fan, desk fan, wall fan, ceiling fan and ground fan etc., and structure is simple, and cost is low, easy to use.
3, front shroud connecting end edge is drawn close formation one to central direction extension and is enclosed the connection edge that width is front shroud diameter 1/5th, front shroud, back cover are connected to form a complete protective housing by crimp, after moving behind crimp mounting point, avoid crimp to be in flabellum blade front and block the air-out of fan, to strengthen air supply areas.
4, front shroud connecting end edge is drawn close formation one to central direction extension and is enclosed the connection edge that width is front shroud diameter 1/5th, front shroud, back cover are connected to form a complete protective housing by crimp, this structural design moves a certain distance after crimp, thus avoid flabellum blade having 5 ° of blades to 40 ° of arc valgus angle and encounter the crimp being in position, middle, use safety.
[accompanying drawing explanation]
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is flabellum and fan electromotor package assembly schematic diagram in the utility model.
Fig. 2 lands fan structure schematic diagram in the utility model.
[embodiment]
As depicted in figs. 1 and 2, a kind of New Type of Fan, comprise flabellum 81 and fan electromotor, fan electromotor is arranged on motor cabinet 82, flabellum 81 is by fan electromotor driven rotary, flabellum 81 blade is along long axis direction camber, and flabellum 81 blade outer end arc valgus angle scope is between 5 ° to 40 °, and flabellum 81 blade has 5 ° of blade 810 length to 40 ° of arc valgus angle account for whole flabellum 81 blade axial length 1/8th or 1/4th.
In present case, flabellum 81 blade is placed in a protective housing, protective housing comprises front shroud 91, back cover 92 and crimp 93, front shroud 91 connecting end edge is drawn close formation one to central direction extension and is enclosed the connection edge 910 that width is front shroud diameter 1/5th, and front shroud 91, back cover 92 are connected to form a complete protective housing by crimp 93.This structural design moves a certain distance after crimp, thus avoids flabellum 81 blade having 5 ° of blades 810 to 40 ° of arc valgus angle and encounter the crimp being in position, middle, use safety.
As shown in Figure 2, motor cabinet 82 is provided with button 83 of shaking the head, motor cabinet 82 is connected with base 85 by supporting frame 84, supporting frame 84 is provided with timer 86 and switching knob 87.
The utility model is not limited to above-mentioned mode of execution, if do not depart from spirit and scope of the present utility model to various change of the present utility model or distortion, if these are changed and distortion belongs within claim of the present utility model and equivalent technologies scope, then intention of the present utility model also comprises these changes and distortion.
