Abstract
The utility model discloses a wind pumping device for the coal stoves, including a motor(1), a drive mechanism with is connected with the motor(1), and fan blades(8) which are connected with the drive mechanism and positioned on a smoke pipe(9). The utility model is small and flexible in structure and can be directly arranged on the smoke pipe. When the firing or the fire increase of the coal stove is needed, not only the air pumping device can speed the running of the air in the stove so as to assist the burning, but also the dust generated during the air pumping, is placed in the coal stove or the smoke pipe or exhausted out of the chamber so as to greatly protect the indoor environment. Besides, the utility model can work through the hand rocking when no electricity is provided.
Description
Technical field
The utility model relates to a kind of coal stove apparatus, the extractor fan that particularly a kind of coal stove is used.
Background technology
At present, in the rural area, the coal stove utilization rate is still very high.Coal stove is lit a fire or when need strengthening firepower, comes combustion-supportingly usually with instruments such as fan, air blasts, and this makes that the kitchen is inner and produce a large amount of dusts, has destroyed the internal environment in kitchen.Area in poor short of electricity; When perhaps cutting off the power supply in the daily life, electronic air blast can't be brought into play its effect.Combustion-supporting instrument commonly used uses for a long time, inner dust stratification easily, thus cause the not normal or even damage of its running.
Summary of the invention
The purpose of this utility model is, a kind of coal stove extractor fan is provided.This coal stove extractor fan can guarantee under indoor dustless prerequisite combustion-supporting.
The utility model is to constitute like this, and its structure comprises motor 1 and connected transmission mechanism, and what be connected with transmission mechanism is installed in fan blade 8 in the smoke pipe 9.
Above-mentioned coal stove extractor fan, be characterized in, the structure of described transmission mechanism comprises: the worm-wheel shaft 2 that is connected with motor 1, the worm gear 3 that is connected with worm-wheel shaft 2, worm gear 3 links to each other with worm screw 4, worm screw 4 tops are fastened with gear 5, and gear 5 links to each other with the connecting axle 7 that fan blade 8 is housed through termination gear 6.
Aforesaid coal stove extractor fan is characterized in, also comprises a driven by shaking mechanism, constitutes to comprise rocking bar 10 and the connected shift drive mechanism of being made up of driving wheel 11 and driven pulley 12.
Aforesaid coal stove extractor fan is characterized in, described transmission mechanism encapsulates with housing 14.
Compared with prior art, structure of the present utility model is small and exquisite, can be directly installed on the smoke pipe.Coal stove is lit a fire or when need strengthening firepower; extractor fan can not only impel air to flow fast in coal stove, plays combustion-supporting effect, and the dust that is produced in the exhausting process; be in coal stove and smoke pipe the inside or be discharged into outdoorly, indoor environment is played very big protective effect.In addition, the utility model also can be worked by hand mode under the situation that does not have electricity.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is structural representations that the utility model uses driven by shaking mechanism;
Accompanying drawing 3 is right views of the present utility model;
Being labeled as of accompanying drawing: 1-motor, 2-worm-wheel shaft, 3-worm gear, 4-worm screw, 5-gear, 6-termination gear, 7-connecting axle, 8-fan blade, 9-smoke pipe, 10-rocking bar, 11-driving wheel, 12-driven pulley, 13-electric machine casing, 14-housing, 15-hand-operated mechanism housing.
The specific embodiment
Embodiment 1.A kind of structure of coal stove extractor fan as shown in Figure 1, it comprises motor 1 and connected transmission mechanism, what be connected with transmission mechanism is installed in fan blade 8 in the smoke pipe 9.Wherein, an end that is configured to worm-wheel shaft 2 of described transmission mechanism is connected with the turning cylinder of motor 1, the other end passes the outer wall of smoke pipe 9 and connects worm gear 3, two snap rings are fixed on worm-wheel shaft 2 on the outer wall of smoke pipe 9, worm gear 3 links to each other with worm screw 4, worm screw 4 tops are fastened with gear 5, and gear 5 links to each other with termination gear 6, and termination gear 6 is fixed on connecting axle 7 bottoms.Fan blade is the top that is contained in connecting axle 7.Place the motor 1 on smoke pipe 9 outer walls to be encapsulated by electric machine casing 13, transmission mechanism is encapsulated by housing 14, thereby prevents that the coal stove extractor fan from causing damage because of dust stratification.
During use, connect motor power (power supply can be an external power supply, also can be battery supply), power input to a machine is when 10W～20W, and motor just can make fan blade quick rotation in smoke pipe, promptly exhausting.
This coal stove extractor fan also comprises a driven by shaking mechanism, its structure as shown in Figure 2, driven by shaking mechanism is made of rocking bar 10 and the connected shift drive mechanism of being made up of driving wheel 11 and driven pulley 12; Driven by shaking mechanism can be by device case 15 encapsulation.When not having electricity, can take off motor, driven by shaking mechanism is docked with transmission mechanism, rotating rocker just can make fan blade quick rotation in smoke pipe, promptly exhausting then.
