Abstract
The utility model discloses a portable electric fan with foldable blades belonging to the living electrical appliance for daily use; the electric fan is characterized in that the blades (1) opposite to the blades seat (2) can rotate about 180 DEG so that the blades (1) are provided with two states of extending and folding; the utility model mainly solves the problem that the existing flashlight type fan is inconvenient to be carried because the blades can not be folded; the utility model has the advantages of simple structure, small size and convenient portability; when the blades are extended, the rotation diameter is large, and the wind rate is sufficient.
Description
The utility model belongs to life daily-use electrical appliance, particularly a kind of fan blade Foldable cellular electric fan.
The portability electric fan that existing individual uses is a kind of flashlight type electric fan that uses battery, and its purposes is to replace traditional Hand swing fan.Fan blade can not fold when this electric fan did not use, and overall volume can not dwindle, and carried very inconvenient.Because of the shortcoming that exists inconvenience to carry, cause this electric fan to fail to be used widely.
The purpose of this utility model is to overcome the shortcoming that above-mentioned electric fan inconvenience is carried, and provides a kind of fan blade in use deployable, fan blade Foldable cellular electric fan when not using for this reason.Mainly the technical problem of Xie Jueing is that the folding back of fan blade overall volume is little and fan blade expansion back swing diameter is big, thereby not only easy to carry, and air quantity is big.
Aufbauprinciple of the present utility model is seen accompanying drawing 1.Shown in figure, this electric fan mainly is made up of fan blade (1), fan blade seat (2), position limit pin (3), motor (4), housing (5), power box (6) and switch (7) etc.One end of housing (5) connects power box (6), the interior assembling motor of housing (5) (4), and the axle of motor (4) is gone up assembling fan blade seat (2), and fan blade seat (2) is gone up assembling fan blade (1).The petiole apparent wind trichidium (2) of fan blade (1) can turn round about 180 degree, and when a direction revolution, fan blade launches to become working state, and when turning round round about, fan blade is folded into the carrier state of inoperative.See accompanying drawing 5 along the A among Fig. 1 to view after fan blade is folding.See accompanying drawing 6 along the sectional drawing of b-b line among Fig. 1.
Fan blade among the figure (1), one end are the petiole part, and the other end is the blade part.
Petiole is a shape basically, and said axle shape is cylinder or circular cone or screw shaped.Has the hole that is used to assemble position limit pin (3) on the petiole.Position between petiole or petiole and blade has the curved shape that angle is the obtuse angle, and the angle at this obtuse angle is preferably 135 degree.The quantity of fan blade is no less than two, generally can be two to four.The spoon of blade of fan blade is cylinder curved surface or conical surface or spiral camber.The petiole and the blade of fan blade (1) are connected as a single entity, and are connected as a single entity after also can making respectively again.
Fan blade seat (2) among the figure has the hole of an assembling motor axle and the hole of several assembling fan blade petioles on it.The hole of said assembling petiole is circular hole or taper hole or screw.Fan blade seat (2) is gone up the hole of assembling motor moving axis and the hole of assembling petiole, and its wire clamp angle, center is an acute angle, and the angle of this acute angle is preferably 45 degree.Go up the side that each assembles the petiole position at fan blade seat (2), have the groove that communicates with the hole of assembling petiole, petiolar position limit pin (3), the restriction of groove in this groove makes fan blade (1) apparent wind trichidium (2) can turn round about 180 degree.
Power box among the figure (6), its inner chamber is in order to hold the socket of battery (8) or low-voltage alternating-current rectifier or ABAP Adapter.Switch (7) is housed on the power box (6).
Of the present utility model being characterised in that: the linkage structure of fan blade (1) and fan blade seat (2) connection part, it is fan blade (1) can turn round about 180 degree with respect to fan blade seat (2) linkage structure, the said linkage structure of turning round, be cylinder in circular hole or circular cone in taper hole or screw rod rotating linkage structure in screw.
The linkage structure of cylinder in circular hole seen accompanying drawing 1.
The linkage structure of circular cone in taper hole seen accompanying drawing 2.
The linkage structure of screw rod in screw seen accompanying drawing 3.
Of the present utility model can rotating syndeton, two kinds of situations about cooperatively interacting are arranged, first kind of situation as mentioned above, be the petiole of fan blade (1) be the axle shape and fan blade seat (2) with The position that petiole cooperates is poroid; The second situation is then opposite, is that the petiole of fan blade (1) is poroid and position that fan blade seat (2) cooperates with petiole is the axle shape. The syndeton of the cylinder of second situation in circular hole seen accompanying drawing 4, and circular cone reaches syndeton and the accompanying drawing 4 of screw rod in screw in taper hole similar.
Because fan blade (1) and fan blade seat (2) have the said structure characteristics and fan blade (1) apparent wind trichidium (2) can turn round about 180 architectural features of spending, make fan blade (1) through the revolution of different directions, launch and folding two states and have fan blade (1).
Compared with the prior art the utility model has following advantage:
(1) the folding rear overall volume of fan blade can dwindle, and is easy to carry.
(2) the fan blade tactical diameter is big, and air quantity is big.
All available plastics or the nylon manufacturings of fan blade of the present utility model (1), fan blade seat (2), housing (5), spacer pin (3) and power pack (6).
Embodiment one
See accompanying drawing 1.Fan blade (1) quantity is two, petiole be cylindric and have 135 the degree angles curved shapes, blade is the cylinder curved surface, petiole and blade are connected as a single entity.Have the hole of an assembling motor axle and the circular hole of two assembling fan blade petioles on the fan blade seat (2).The hole of assembling motor axle and the hole of assembling the fan blade petiole, center line angle are 45 degree.Power box (6) is cylindrical, can hold battery one joint No. one.The folding back of electric fan blade (1) profile near cylindrical, boundary dimension: 45 millimeters of diameters are high 120 millimeters.Fan blade (1) launches 200 millimeters of back swing diameters.
Embodiment two
Present embodiment adopts the low-voltage alternating-current rectifier to replace battery, and two kinds of forms are arranged, and a kind of is that rectifier is packed within the power box (6), and external AC power supply, another kind are only to assemble power socket within power box (6), external AC adapter.Indoor (for example family and office) that present embodiment is adapted at ac power supply uses.
The embodiment of expanded function
Because the structure and the specification of the motor of the electric shaver of motor of the present utility model (4), housing (5), power box (6), switch (7) etc. and prior art, housing, power box, switch etc. are basic identical, therefore as the utility model and electric shaver are combined, then the utility model can be expanded into the fan blade Foldable cellular electric fan that fan shaves dual-purpose.Also can combine, be expanded into various dual-purpose electric fans with other hand-held household electric appliance.
