Abstract
The utility model relates to an all position vertical blade fan, belonging to the technical field of ventilation. The utility model is composed of a base, a motor, a casing, blades, a safety shield for blades, and an electric switch. The utility model is characterized in that the periphery of the blade core (6) is provided with 3 or 4 blades, and the blade plane is parallel to the axial direction of a crankshaft. The utility model has the advantages of all position ventilation, and simple structure, and overcomes the defect of narrow ventilation range existing in the prior art. The utility model can be widely used for the ventilation in countryside, and urban and rural areas.
Description
The utility model relates to the improvement of fan structure, belongs to aeration technology neck city.
Present commercially available electric fan is made of other parts of base, motor, casing, fan blade, blade cover, head-shaking device and electric switch, for grasping cold summer, people provide condition, but the ventilation scope only is limited to the place ahead, the angle of shaking the head can not make electric fan people all around can both obtain to ventilate in 90 °～180 ° scopes.
The purpose of this utility model provide a kind of can to around can realize the comprehensive vertical fan blade electric fan of blowing simultaneously.
The utility model adopts following technical proposal to solve:
The utility model comprises base, motor, casing, fan blade safety enclosure and electric switch, and motor arbor and fan blade core center are connected and fixed, and it is characterized in that being provided with around the fan blade core fan blade 3 or 4 and fan blade plane and arbor parallel to an axis.
By said structure as can be known, the utlity model has following technique effect:
Fan blade plane and the axial angle of arbor by myopia vertical change into parallel, therefore fan blade rotates with arbor, 360 ° of scopes all can obtain ventilating, thereby before and after the solution electric fan, about around the people can both obtain ventilating, this is suitable especially to the rural area, the farm house neighbours enjoy the cool in the outside in evening in summer, enjoy the cool round this comprehensive vertical fan blade electric fan, talking of everything under the sun does not have some local flavor.
2. got rid of head-shaking device, made structure simpler.

1 for fan blade safety enclosure main body, 2 main body upper aperture, 3 fan blades, 4 main body steel wires, 5 fan blade core loam cakes, 6 fan blade cores, 7 motor rotary shafts, 8 fan blade safety enclosures go to the bottom that mesopore, 9 motor casings, 10 electric switches, 11 electric fan bases, 12 fan blade safety enclosures and casing attachment hole, the 13 fan blades outside are that lonely shape, 14 fan-shaped fan blade inclined-planes, 15 fan blade safety enclosures are gone to the bottom, 16 casing upside projectioies, the protruding attachment hole of 17 upsides among the figure.
The utility model is described in further detail with reference to the accompanying drawings below:
Referring to Fig. 1, the bottom is electric fan base (11), in establish electric switch (10) and casing (9), in casing, set firmly a motor, the arbor of motor (7) is upwards drawn, and connects fan blade core (6) at an upper portion thereof, around the fan blade core or establish by three fan blades or establish four fan blades (3), the plane of fan blade and arbor parallel to an axis make wind all directions to the axle surface of revolution.See Fig. 2,3, fan blade and fan blade core are tangent direction by circular arc trisection (adorning 3 fan blades) or quartering setting, fan blade and fan blade core Placement are divided into two kinds, a kind of is to fuse, another kind is that assembling ﹠ disassembling connects, and the horizontal undulate structure of the outlet air surface of fan blade makes air-out be fluctuation shape, lid (5) is established in fan blade core top, and this lid and arbor are to be threaded.The fan blade safety enclosure comprises main body (1) and goes to the bottom (15) that hole (2) is established in main body top, establishes mesopore (18) on go to the bottom (15), the effect in these two holes all provides air intake, establishes steel wire around the main body, and purpose is ventilated together, two safety effects.
When ventilating around only needing part, round wire should change " venetian blind " shape into, when " venetian blind " axially faces toward fan blade, then 360 ° of scope air-out, when the plane of part " venetian blind " faced toward fan blade, then the air-out of this part was blocked, and also is that outlet air surface is less than 360 °.
See Fig. 4,5, a kind of shape of fan blade is rectangular, and the outside curved (13), the shape of another kind of fan blade is fan-shaped (14).See Fig. 6, the casing top is three or four projectioies (16), purpose be make the fan blade safety enclosure go to the bottom (15) and casing (9) between air intake passage is arranged, simultaneously on projection (16), establish hole (17), this hole (17) are connected and fixed by screw with hole (12) on go to the bottom (15).
Claims (5)
1. comprehensive vertical fan blade electric fan for ventilation usefulness, comprise base, motor, casing, fan blade safety enclosure, electric switch, motor arbor and fan blade core center are connected and fixed, and it is characterized in that being provided with around the fan blade core fan blade 3 or 4, fan blade plane and arbor parallel to an axis.
2. by the described comprehensive vertical fan blade electric fan of claim 1, it is characterized in that fan blade is fan-shaped or curved rectangular-shaped on one side.
3. by claim 1,2 described comprehensive vertical fan blade electric fans, it is characterized in that establishing hole (2) above the fan blade safety enclosure main body, establish mesopore (18) on go to the bottom (15).
4. by claim 1,2 described comprehensive vertical fan blade electric fans, it is characterized in that the steel wire (4) of fan blade safety enclosure is " venetian blind " shape, " venetian blind " axially faces toward fan blade facing to the plane of fan blade or " venetian blind ".
