Description
Technical field
This utility model relates to fan technology field, is specially a kind of hand held small fan.
Background technology
Fan refers to that hot day takes cool apparatus electric fan so as to raw wind, is the device producing air-flow by electric drive, and the fan energising of interior configuration carries out rotating the effect that chemical conversion natural wind reaches to enjoy the cool later；Common are stand fan, desk-top fan, wall fan and ceiling fan etc. at present, respectively have advantage, played its due cooling perspiration removing effect in the family with some public places.
Existing electric fan is relatively larger due to volume, and electric fan is Portable belt not, and namely common paper fan is not durable, and it is also poor to drive summer-heat effect, uses and has inconvenience.
Summary of the invention
Prior art is difficult to meet the needs of people, in order to solve above-mentioned Problems existing, the utility model proposes a kind of hand held small fan, it is simple to carry, it is not necessary to power supply, realizes airflow effects for power holding during use, and energy-conserving and environment-protective are very useful.
For achieving the above object, this utility model provides following technical scheme: a kind of hand held small fan, including the first shell, second housing, flabellum assembly and driving handle；Described first shell and second housing are fixed by screw, and are formed with cavity between the first shell and second housing；It is disposed with the first gear, the second gear and the 3rd gear in described cavity, and the first gear, the second gear and the 3rd gear are fastened between the first shell and second housing by rotating shaft；Described 3rd gear is additionally provided with ratchet；Described driving handle is arranged between the first shell and second housing, and driving handle top is connected with ratchet wheel block one end, and the described ratchet wheel block other end interlocks with ratchet, described ratchet wheel block is also arranged with spring, and spring makes ratchet wheel block and driving handle automatically reset；Described flabellum assembly is fixedly installed on the first shell by the first casing cover, and the rotating shaft on flabellum assembly and the first gear connects.
Further, described ratchet, the 3rd gear and rotating shaft are fixing connects.
Further, engage respectively between described first gear, the second gear and the 3rd gear.
Compared with prior art, the beneficial effects of the utility model are: this hand held small fan, it is simple to carry, it is not necessary to power supply, airflow effects is realized for power holding during use, energy-conserving and environment-protective, very useful, commonly used, all right building body, simple to operate, practical, it is easy to promote the use of.

Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection.
Refer to Fig. 1-3, a kind of embodiment that this utility model provides: a kind of hand held small fan, including the first shell 1, second housing 2, flabellum assembly 3 and driving handle 4；Described first shell 1 and second housing 2 are fixed by screw, and are formed with cavity between the first shell 1 and second housing 2；It is disposed with the first gear the 5, second gear 6 and the 3rd gear 7 in described cavity, and first gear the 5, second gear 6 and the 3rd gear 7 are fastened between the first shell 1 and second housing 2 by rotating shaft 8；Described 3rd gear 7 is additionally provided with ratchet 9；Described driving handle 4 is arranged between the first shell 1 and second housing 2, and driving handle 4 top is connected with ratchet wheel block 10 one end, described ratchet wheel block 10 other end and ratchet 9 interlock, and described ratchet wheel block 10 is also arranged with spring 11, and spring 11 makes ratchet wheel block 10 and driving handle 4 automatically reset；Described flabellum assembly 3 is fixedly installed on the first shell 1 by the first casing cover 12, and flabellum assembly 3 is connected with the rotating shaft 8 on the first gear 5；Described ratchet the 9, the 3rd gear 7 and the fixing connection of rotating shaft 8；Engage respectively between described first gear the 5, second gear 6 and the 3rd gear 7.
This utility model hand held small fan is in use, grasp driving handle 4, firmly driving handle 4 is held to the palm of the hand, at this moment, driving handle 4 drives ratchet 9 to rotate by ratchet wheel block 10, ratchet 9 drives rotating shaft 8 to rotate, and drives the 3rd gear 7 to rotate, and the 3rd gear 7 drives the second gear 6 to rotate, second gear 6 drives the first gear 5 to rotate, through the engagement of each gear, speed change, flabellum assembly 3 quickly rotates, and return spring 11 is opened.When hands is no longer exerted oneself, and unclamps driving handle 4, driving handle 4 connects the return spring 11 on ratchet wheel block 10 under elastic force effect, and driving handle 4 retracts the position held before driving handle 4；Again hold lower driving handle 4, driving handle 4 again can driving pawl 9, each rotatable parts rotate again；So repeatedly, flabellum assembly 3 will high-speed rotation, produce wind-force, it is achieved airflow effects.
It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and when without departing substantially from spirit of the present utility model or basic feature, it is possible to realize this utility model in other specific forms.Therefore, no matter from which point, embodiment all should be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims rather than described above, it is intended that all changes in the implication of the equivalency dropping on claim and scope included in this utility model.Any accompanying drawing labelling in claim should be considered as the claim that restriction is involved.
