A driving shaft is pivoted above a fan shaft, the other end of the driving shaft is fixedly provided with a rocking handle and the driving shaft is connected with the fan shaft via a differential gear set. The utility model is convenient for carrying and holding and can rapidly output wind so as to help the combustion of stove fire.
Description
The utility model relates to a kind of air blown producer.
When camp in general open air, regular meeting faces the difficulty of the calm devote every effort to help combustion of lighting a fire.So Chang Kejian incites wind with newspaper or cardboard, so that stove fire is more prosperous.But the mode of so lighting a fire not only bothers effort, and the combustion-supporting effect that is obtained is also very limited.So if can develop a kind of conveniently going out and carry, the utensil that can help stove fire to rise fast will make mountain-climbing, camp or barbecue becomes more convenient.
The purpose of this utility model is to provide a kind of portable easily air blown producer that carries, grips, drive laborsaving and air-supply fast.
The technical solution of the utility model is to provide a kind of portable air blown producer, is provided with a housing with wind stomach chamber, and the indoor fan that is pivoted of the wind stomach of this housing is characterized in that:
Respectively there is the wind inlet that is communicated to wind stomach chamber the both sides of this housing, housing differs from the cephalolateral margin of wind inlet, protrude out an exhaust outlet that communicates with wind stomach chamber, and housing differs from another edge of exhaust outlet, then set firmly a handle, the fan shaft of fan protrudes a side of housing, and a live axle is pivoted in the top of fan shaft, the end in addition that this live axle differs from housing sets firmly a rocking handle, and this live axle connects fan shaft by differential gear set.
Described portable air blown producer is characterized in that:
This differential gear set is included in fan shaft and protrudes the small gear that shell ends sets firmly, and that set firmly on live axle and gearwheel this pinion.
Described portable air blown producer is characterized in that:
Be pivoted with a tower shape gear train between small gear on this fan shaft and the gearwheel on the live axle, this tower shape gear train has the large and small gear that is installed in the same rotating shaft, make the small gear and the engagement of the gearwheel on the live axle of this tower shape gear train, and make the gearwheel of tower shape gear train and the pinion on the fan shaft.Described portable air blown producer is characterized in that:
Housing is provided with a gear housing and is overlying on the gearwheel outside on this tower shape gear train and the live axle.
Described portable air blown producer is characterized in that:
The sheathed guide duct of the exhaust outlet of housing with an angle tilt.
The utility model is easy to carry and grips use, but and utilize the transmission quick rotation fan of large and small gear, air-supply is quick and laborsaving during use.
Further specify specific structural features of the present utility model and purpose below in conjunction with accompanying drawing.
Brief Description Of Drawings:
Fig. 1: the schematic appearance of the utility model preferred embodiment.
Fig. 2: the perspective exploded view of the utility model preferred embodiment.
Fig. 3: the longitudinal profile schematic representation of the utility model wind stomach part.
Fig. 4: the utility model gear cap is joined the generalized section of speed.
At first please cooperate referring to shown in Fig. 1,2.The portable air blown producer of the utility model is by the synthetic housing 10 of two vent covers, 11 covers.The opposite side that two vent covers, 11 covers close is fanned ccontaining wind stomach chambers 110 12 but respectively be arranged with an air feed.Fan 12 is fixedly arranged on the fan shaft 13, fan shaft 13 is hubbed in the wind stomach chamber 110 of two vent covers 11, and an end that makes fan shaft 13 protrudes affixed one first small gear 130 in a vent cover 11 outsides, make vent cover 11 tops that are positioned at these first small gear, 130 sides, form one and upwards be the extension part 14 that planar is extended.Extension part 14 is positioned at the top of fan shaft 13, and a rotating shaft 16 that is installed with first gear 160 is pivoted.First gear 160 in this rotating shaft 16 forms engagement with first small gear 130 of fan shaft 13, and make this rotating shaft 16 differ from the axial positions of first gear 160, set firmly again and the second moving together small gear 161 of first gear 160, make 161 of the first gear 160 and second small gears form a tower shape gear train.Vent cover 11 extension parts 14 are positioned at the top of rotating shaft 16, and the live axle 17 that then is pivoted again makes and sets firmly a second largest gear 170 on this live axle 17.This second largest gear 170 forms engagement with second small gear 161 of rotating shaft 16.The extension part 14 outer covers again of vent cover 11 cover a gear cap 15, and the end in addition that this live axle 17 differs from extension part 14 protrudes out the gear cap 15 outer rocking handles 18 that set firmly.
In addition, this housing 10 is positioned at the side of each vent cover 11, forms the exhaust outlet 111 that communicates with 110 inside, wind stomach chamber respectively.The cephalolateral margin place that housing 10 is positioned at two vent covers, 11 sides protrudes out an exhaust outlet 112 (as shown in Figure 1) that communicates with wind stomach chamber 110.The guide duct 113 that can sheathedly have an angle tilt on exhaust outlet 112 ora terminalis.The relative rear side of housing 10 is then established one and is available for users to the convenient handle 19 of mentioning that grips.
By this, shown in Fig. 3,4, the user can shake rocking handle 18 and the second largest gear 170 on the live axle 17 is rotated when the utility model used; And come transmission second small gear 161 with second largest gear 170, and being formed synchronously, rotating shaft 16 and first gear 160 rotate.Rotate first small gear 130 by first gear 160 again, first small gear, 130 drive fan shafts 13 and fan 12 are rotated in wind stomach chamber 110.Through fan 12 air is sucked by wind inlet 111, and by exhaust outlet 112 wind is sent outside the wind stomach chamber 110, the guiding by guide duct 113 makes wind help the burning of stove fire to the stove fire place again.
