Auxiliary power source is equipped with the main body of dust collector,
The auxiliary power source includes being arranged at air-flow multiplier on the dust absorbing air passage, for supplying to air-flow multiplier Second motor of gas and the inlet channel for the second motor connection outside atmosphere,
Second motor is connected with the power supply.
Further, first motor is located in the exhaust air flue, and first motor it is peripheral with it is described Airspace is left between the wind path wall of exhaust air flue.
Further, the air-flow multiplier includes annular compartment and the annular fissure towards first motor.
Further, the grey unit of the collection includes dust casket and filter screen.
Further, the dust casket is integrally formed with the filter screen.
Further, the grey unit of the collection is detachably arranged on the main body of dust collector.
Further, the outlet air end of the exhaust air flue is equipped with outlet air filter screen.
Further, first motor is in parallel with second motor.
The beneficial effects of the utility model are mainly reflected in:
1. using double dynamical cooperation, the air inflow of hand-held cleaners is improved, so as to improve dust collection efficiency.
2. air-flow multiplier reduces energy loss as auxiliary power while air inflow is improved.
3. since air inflow is effectively improved, so as to increase the area at dust absorbing air passage air draught end, can effectively expand The dust suction scope of dust catcher.
4. dual power source can coordinate or independently working, when one of power source produces failure, another power source according to So it can realize running.
Brief description of the drawings
Fig. 1 is the structure diagram of the double dynamical hand-held cleaners of the utility model.
Embodiment
The utility model provides a kind of double dynamical hand-held cleaners.Below in conjunction with attached drawing to technical solutions of the utility model into Row is described in detail, so that it is more readily understood and grasps.
Double dynamical hand-held cleaners, as shown in Figure 1, including the main body of dust collector 2 equipped with hand holding handle 1 and being arranged at dust catcher Power supply 3 in main body 2, main body of dust collector 2 is interior to be equipped with the grey unit 5, first of dust absorbing air passage 4, collection along air inlet/outlet flow path successively Motor 6 and exhaust air flue 7, power supply 3 are connected with the first motor 6, and 6 face dust absorbing air passage 4 of the first motor.
First motor 6 obtains the power supply of power supply 3, produces distinguished and admirable by the disengaging of dust absorbing air passage 4 towards exhaust air flue 7 Footpath, dust absorbing air passage 4 is in negative pressure state, the air port end absorption surrounding air of dust absorbing air passage at this time, and dust is sucked dust suction wind In road, hence into the grey unit of collection, dust-absorbing function is realized.
The auxiliary power source for being used for increasing exhaust air flue induction air flow ratio, auxiliary power are equipped with this case, in main body of dust collector 2 Air-flow multiplier 8 that source includes being arranged on dust absorbing air passage 4, for the second motor 9 for being supplied to air-flow multiplier 8 and be used for Second motor 9 connects the inlet channel 10 of outside atmosphere, and the second motor 9 is connected with power supply 3.
Wherein, air-flow multiplier 8 includes annular compartment 81 and the annular fissure 82 towards the first motor 6.Air-flow multiplier Structural principle:By the annular fissure of a circle narrower in width of inner side, the air stream ejected by annular fissure is because of health It is close to inner wall flowing up to effect, because air is forced to produce by boasting in this circle, drives neighbouring air towards the One motor sprays, and the air capacity passed through can increase to 15 times, speed per hour can highest increase to 35 kilometers/hour.Transported at a high speed using one The negative pressure region that dynamic air jet produces at nozzle rear, the air of draw ambient follow high-speed jet to produce flowing.
More specifically describe, intake caused by dust absorbing air passage 4 is subject to the common work of the first motor 6 and the second motor 9 With, as shown in the direction of arrow in Fig. 1, the first motor 6 first is produced by the air inlet flow path of dust absorbing air passage 4 to exhaust air flue 7, next Be the second motor 9 produce by inlet channel 10, air-flow multiplier 8, dust absorbing air passage 4 to exhaust air flue air inlet flow path, therefore, The air inflow of dust absorbing air passage 4 is produced jointly by the first motor 6 and the second motor 9, is drastically increased the air inflow of dust catcher, is made The dust collection efficiency higher of dust catcher is obtained, can be applicable in and larger heavier debris is absorbed.Also, since air inflow is larger, because This can increase the air inlet open area of dust absorbing air passage 4, so as to expand the dust suction scope of dust catcher.
In preferred embodiment, the first motor 6 is located in exhaust air flue 7, and the periphery of the first motor 6 and exhaust air flue 7 Wind path wall between leave airspace 11.It is increased by air-flow multiplier institute that the airspace 11 can discharge the second motor 9 Throughput, has releived and has flowed through the wind-guiding pressure of the first motor 6, realizes the quick of increase air-flow and is discharged to, while reduces wind and make an uproar, and drops Caused noise in low dust catcher operational process.
Refinement description is carried out to this case, collects grey unit and is detachably arranged on the main body of dust collector.The grey unit 5 of collection includes Dust casket 51 and filter screen 52.Also, dust casket 51 is integrally formed with filter screen 52.Dismountable convenient dismounting of collecting unit of dust is clear Clean cleaning, improves user experience, and dust casket 51 is integrally formed with filter screen 52, easy to assemble, reduces installation difficulty.Need It is noted that this case can also further optimize, the side that dust casket 51 is located at dust absorbing air passage 4 is equipped with the arc for preventing dust backflow Shape barrier, ensures that the dust in dust casket will not flow back.
In addition, the outlet air end of exhaust air flue 7 is equipped with outlet air filter screen 12, after preventing that collecting grey unit leakage occurs, dust is again It is discharged to the outside, pollutes external environment condition.
Finally, the first motor 6 is in parallel with the second motor 9, when one of motor breaks down, another motor according to It can so realize and work independently.It should be noted that the circuit relationships of power supply and the first motor and the second motor are in this case Existing parallel circuit, thus eliminate physical circuit connection repeat and circuit diagram.
By above description it can be found that the utility model uses double dynamical cooperation, the air inlet of hand-held cleaners is improved Amount, so as to improve dust collection efficiency.Air-flow multiplier reduces energy damage as auxiliary power while air inflow is improved Consumption.Since air inflow is effectively improved, so as to increase the area at dust absorbing air passage air draught end, it can effectively expand dust catcher Dust suction scope.Dual power source can coordinate or independently working, and when one of power source produces failure, another power source is still It can realize running.
Above the technical solution of the utility model fully describe, it is necessary to explanation is, the tool of the utility model Body embodiment is simultaneously not limited by the description set out above, and those of ordinary skill in the art exist according to the Spirit Essence of the utility model All technical solutions that structure, method or function etc. are formed using equivalents or equivalent transformation, all fall within this reality Within new protection domain.
