Description
Technical field
The utility model is a kind of people's daily living article, particularly relates to a kind of articles for use of people's functions of relieving summer heat, antithermic in summer.
Background technique
Known, summer, fan has been articles for use that people's functions of relieving summer heat, antithermic can not lack suddenly, the rotating power of prior art drive fan is a motor, power supply is a kind of energy easily, but power supply simultaneously also is the energy that is becoming tight a kind of day, from China to the world wide all in the energy of advocating thriftiness, using electricity wisely.Therefore, be necessary the electric fan of prior art is done some improvement and additional.
Everybody all has cognition; summer; sometimes outdoorly blowing powerful wind; but but there is not a breath of air indoor; this is not window not to be opened; but because the window in house towards inconsistent with the direction of blowing, so the time regular meeting strong wind your writing and can not advance mood and phenomenon that the mind is more worried out of doors appears seeing helplessly.
Raising along with people's living standard; people's quality of life at home requires also improving; even house window towards being consistent with wind; natural wind is directly scraped within doors but people are unwilling; because in the direct inlet chamber of natural wind, also usually can bring a large amount of ashes and dirt into simultaneously; people have proposed higher life and required: should allow in wind energy enters house, dust that again mustn't be outdoor also enters within doors simultaneously.
Summary of the invention
The purpose of this utility model is intended a kind of fan without electric energy is provided, and makes full use of natural wind energy, and it is indoor only to allow outdoor wind advance, and does not allow outdoor dust rubbish advance indoor.
The purpose of this utility model so realizes.
Technical characteristics of the present utility model is, at indoor and outdoors the helical runner of two band fan leaves respectively arranged, and assigns on the bearing support, and one is transmitted flexible axle the bearing at two ends is coupled together.
Its feature is that also outdoor impeller diameter is greater than the diameter of indoor impeller.Or outdoor diameter with indoor impeller is identical, but the spiral angle of outdoor impeller is greater than the spiral angle of indoor leaf.
Transmit flexible axle by central rotating shaft core be wrapped in a sheath of core outer ring and form, but the integral body free bend, such structure, it is widely-used to rotate transmission on machines such as automobile, motorcycle, equipment, has been mature technique.The cross section of two connecting ends of axle core is special-shaped polygonal, example, triangle, square etc.
The two ends of axle core can be fixedly connected on the fan at two ends, also can be connected with the fan at two ends with the form of patching.
The jointing holes of fan shaft is the special-shaped polygonal hole that matches with the axle core also, as triangle, square etc.
For driving snake is fixed on the fan shaft, can adopt the thread bush form to connect the same principle in indoor and outdoor.Promptly, flexible axle sheath end is made and is with the flange edge of turning up, connecting sleeve is cup-shaped, bottom opening, opening diameter greater than sheath diameter less than the bead diameter, the inwall of connecting sleeve cup-shaped is an internal thread, on the fan shaft bearing outside thread is arranged, the flexible axle sheath is penetrated the oral area of connecting sleeve, bead is stuck in and connects in the running-on, the internal thread of connecting sleeve screws in the outside thread on the bearing support, can connect.
Above connection also can be adopted the bayonet socket form, promptly Yi Shang screw thread changes elastic bayonet lock into, the connecting sleeve inwall does not adopt screw thread, and the wall of cup of connecting sleeve is fluting, resilient inner stopper shape, the mouth that patches at the place of being connected of fan shaft bearing is an outer stopper, after the oral area of connecting sleeve penetrated flexible axle, bead was stuck in and connects in the running-on, and connecting sleeve inserts the mouth that patches of bearing, because flexible seam effect is joined together mutually.
Above-mentioned elasticity card also can be by the spring clip mechanism controls of finger pull type, do not slot, and assemble the spring card article that some fingers are pulled, compressed at the torsion of rotating shaft place of pulling by rotating spring at the wall of cup of connecting sleeve, though this structure is complicated slightly, use more convenient reliable.
The axle bed of outdoor fan is supported on the strut of can regulate direction.The axle bed of outdoor fan is supported on the strut of can regulate direction, and the mode of regulating direction can be, and is penetrated by bolt in the through hole of axle bed and strut, and the structure of loosening, screwing with nut realizes.
Using technical solutions of the utility model, utilize natural wind, no longer need other energy, is a kind of energy-conservation articles for use.Also no longer worried for the indoor motionless phenomenon of outdoor wind your writing.The wind that imports into is also very clean, refrigerant, not with outdoor high temperature and dust.
