Description
The utility model relates to a kind of electric portable fan, is applicable to carry so that in the travelling of hot weather way or the usefulness that the oneself blows in the public place of entertainment.
In the prior art, when hot weather, take car and boat, mountain-climbing is trekked or can only carry fan mostly when watching the film drama in the public place of entertainment of no air-conditioning and ceiling fan or folding fan blows on, because it is irksome that the big Chang Yi of covering of the fan meets the adjacent seat guest, and self is also tired easily and disturb appreciation film and drama effect because of shaking fan for a long time.The past one or two people also once made the miniature toy electric fan that has guard, but the wind wing is, and fixed its radius is very little, air quantity extremely slightly is not enough to be used for the oneself and blows on, and will inevitably cause that the fan volume is excessive to carry inconvenience when adopting larger-diameter fixed wind wing, in fact also can't use.
The purpose of this utility model provide all little very light in weight of a kind of its barrel dliameter length especially as common compact flashlights pattern, its wind wing have in use than major diameter and big air quantity and when stopping using, can be retracted in the electric portable fan on a limit, it can carry at any time that breakdown blows on.
The utility model provides a kind of electric portable fan, be applicable to and carry the usefulness that the oneself blows on, it is by being that front end is equipped with at least one pair of wind wing and wherein feels at ease and is contained in fan head on the motor output shaft, cylindrical shell that connects into upper casing lower casing switch and the motor of installing on the motor fixing frame in tube are formed with battery fan positive pole fan negative pole, it is characterized in that: a, described wind wing should be and radially reaches all blades of curved curved surface of circumferencial direction, and its inner root is the ball body and adopts symmetric mode to be movably arranged on the relative position of a fan side; B, described wind wing upper casing lower casing switch motor fixing frame fan head are the plastics manufacturing, and its mutual connection adopts screw thread, tongue-and-groove and plasticity to squeeze the bulkage formula; C, its cylindrical shell of described electric fan can clamp support on upper shell.Bulb can be installed in its center, described lower casing rear portion, the lower casing tail end can clamp lower cover to compress concentration piece and the anodal torch cathode contact of torch to be installed and to be installed additional switch in addition with common composition lighting mechanism on cylindrical shell in the cylindrical shell that connects into the upper casing lower casing.The anodal torch positive electrical of its described fan tube cathode contact fan negative pole is has the manufacturing of electric conductivity good metal.
The utility model is compared with prior art, and is laborsaving when using common fan to shake to blow on, take up room be unlikely for a short time disturb adjacent seat other people.Have than in the past that fixedly the little electric fan total volume of wind wing formula is small and exquisite, carry very convenient.

Component title in the figure:
1, wind wing 2, upper casing 3, motor 4, switch 5, lower casing 6, battery 7, lower cover 8, bulb 9, concentration piece 10, fan positive pole 11, torch positive pole 12, torch cathode contact 13, fan negative pole 14, motor fixing frame 15, fan 16, support
An accompanying drawings specific embodiment of the present utility model: the lower casing [ 5 ] of making long 50 upper casing [ 2 ] and long 63 with low pressure polyethylene connects to form big two ends, the middle part group cylindrical shell of wooden club shape seemingly slightly with M30 * 1 three fine thread in the middle of it.The motor fixing frame of its front end [ 14 ] is gone up 1.5 volts of miniature motors [ 3 ] that can reach 5000~7000 rev/mins of rotating speeds when the idling lotus of voltage that Toy Factory makes is installed, and the rear portion is close to fan negative pole [ 13 ] No. 2 batteries [ 6 ] are installed.Be connected with fan positive pole [ 10 ] in battery [ 6 ] bottom surface, the cathode contact edge that it is drawn along through motor [ 3 ] rear end of barrel, the switch of installing when the tube side [ 4 ] is when pushing ahead, and the boss of switch [ 4 ] bottom compressing fan positive pole [ 10 ] front end is in contact with it and makes circuit clear motor [ 3 ] be activated rotation.Wind wing [ 1 ] radially reaches all blades of curved curved surface of circumferencial direction for the having of 48 wide 32 average thickness 1.5 that be about of polyethylene from high pressure process manufacturing, its root is connected with the ball head of φ 4 with thick 2 short neck, two wind wings [ 1 ] are packed into symmetrically via short neck and are fanned in the narrow groove of head [ 15 ], wherein φ 4 ball heads then can rotate in fan head [ 15 ], and the output shaft outer end of motor [ 3 ] is then filled in fan head [ 15 ] center hole of spreading.Two wind wings [ 1 ] can carry out the high speed rotating that per minute 2800 changes owing to centrifugal action opens when motor [ 3 ] starts, and suitable air quantity is arranged, two wind wings [ 1 ] can be withdrawn into electric fan cylindrical shell both sides and close up to be encased in the special pouch and carry when stopping.Support [ 16 ] can be in order to upper casing [ 2 ] outside that is contained in the electric fan that assembles, and makes the electric fan can be tilting on the table as the fixing usefulness of electric fan pectinid in triangle tripartite confrontation mode.This electric fan rear portion can also install lower cover [ 7 ] bulb [ 8 ] concentration piece [ 9 ] and torch positive pole [ 11 ] torch cathode contact [ 12 ] and another switch [ 4 ] on cylindrical shell additional, and it is connected as common flashlight so that the double simultaneously usefulness of making flashlight.Electrically conducting member on all circuit of this electric fan all adopts scale copper to make, and all the other remove motor, should adopt plastic stempressing or injection moulding as far as possible outside battery, bulb, the concentration piece outsourcing.The used battery of electric fan [ 6 ] also can adopt No. 5 Cd-Ni batterys or other big small cells so that charging or buy in market, and just the relevant size of its electric fan cylindrical shell need be done corresponding change and revises.
