SUMMERY OF THE UTILITY MODEL
One of the purposes of the utility model is to above-mentioned not enough, provide a many motors hand-held type wireless dust catcher to hope to solve among the prior art that the hand-held wireless dust catcher of the same kind receives the restriction of self volume and weight, vacuum is limited, and suction is not enough, can increase the volume and the weight scheduling technical problem of dust catcher behind large-size impeller and the high-power motor of adoption.
In order to solve the technical problem, the utility model adopts the following technical scheme:
the utility model provides a multi-motor handheld wireless dust collector, which comprises an outer shell, wherein at least two motor fan blade units are arranged inside the outer shell, the two motor fan blade units are communicated with each other through an air channel, and an air outlet of one motor fan blade unit is communicated with an air inlet of the other motor fan blade unit; the motor fan blade unit comprises a motor, and an impeller is mounted on the output end of the motor.
Preferably, the further technical scheme is as follows: the central axes of the impellers of the two motor fan blade units are staggered with each other and fixed into a whole through an air duct.
The further technical scheme is as follows: the motor fan blade unit is characterized in that an air inlet end and an air outlet end are arranged on the outer shell, an air inlet of one motor fan blade unit is communicated with the air inlet end through an air channel, and an air outlet of the other motor fan blade unit is communicated with the air outlet end through the air channel.
The further technical scheme is as follows: the motor power of the two motor fan blade units is the same, and the size of the impeller is the same.
The further technical scheme is as follows: the shell is provided with a hand-held handle.
Compared with the prior art, one of the beneficial effects of the utility model is that: through add the motor fan blade unit more than two in the inside of dust catcher shell body for after the motor fan blade unit communicates each other through the wind channel, the motor can superpose with the produced vacuum of impeller, thereby under the condition of using the motor of original power and original size impeller, does the vacuum that promotes the dust catcher, and then promotes suction, satisfies people to the user demand of the big suction of small-size dust catcher, simultaneously the utility model provides a many motor hand-held type wireless dust catcher simple structure is suitable for industrial production, easily promotes.

Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
Referring to fig. 1, an embodiment of the present invention is a multi-motor handheld wireless vacuum cleaner, including an outer housing 1, and importantly, two independent motor blade units 2 are installed inside the outer housing 1, and the independent motor blade units 2 can also adopt more than two, in this embodiment, two motor blade units 2 are taken as an example to explain the structure of the vacuum cleaner, these two motor blade units 2 are all communicated with each other through an air duct 3, and an air outlet of one of the motor blade units 2 is communicated with an air inlet of the other motor blade unit 2; as shown in fig. 3, the motor blade unit 2 at least includes a motor 21, and an impeller 22 is further mounted on an output end of the motor 21, and after the power supply is turned on, the motor 21 drives the impeller 22 to rotate, so that negative pressure is generated in an air duct in the outer casing 1, and suction force is generated. With this structure, the power of the motor 21 and the size of the impeller 22 can be the same specification, or different specifications can be adopted according to the use requirement and the design of the air duct.
In this embodiment, through add more than two motor fan blade units 2 in the inside of dust catcher shell body 1 for after motor fan blade unit 2 communicates each other through wind channel 3, the produced vacuum of motor 21 and impeller 22 can superpose, thereby under the condition of using motor 21 and original size impeller 22 of original power, also can promote the vacuum of dust catcher, and then promote suction, satisfy people to the user demand of the big suction of small-size dust catcher, especially, be suitable for and use on the handheld wireless dust catcher of little volume, also can not increase the volume of dust catcher, and the weight of dust catcher is general also can be controlled.
Combine fig. 2 shown, according to the utility model discloses a further embodiment, for the mutual vortex interference that appears when avoiding two or more motor fan blade unit simultaneous operation, the inventor staggers the axis of the impeller 22 of two above-mentioned motor fan blade units 2 each other when the design, and wind channel 3 designs to cooperate with it simultaneously to pass through wind channel 3 with two motor fan blade units 2 fixed as an organic whole. Further, as shown in fig. 1, in order to facilitate the two motor blade units 2 to work together, similar to the structure of the similar vacuum cleaner, an air inlet end 11 and an air outlet end 12 are provided on the outer casing 1, and then the air inlet of one of the motor blade units 2 is communicated with the air inlet end 11 through the air duct 3, and the air outlet of the other motor blade unit 2 is communicated with the air outlet end 12 through the air duct 3. Thereby under the effect of motor 21 in two motor fan blade units 2, the air current is held 11 entering by the air inlet on the shell body 1, is discharged by air-out end 12 to at this in-process, the air current at first passes through the filter vat, with the dust and the particulate matter filtering that contain in the air, play the effect of dust removal. Meanwhile, for the convenience of holding by hand, a hand-held handle 13 shown in fig. 1 can be arranged on the outer shell 1.
Referring to fig. 1 and 2, the above preferred embodiment of the present invention is shown in the practical use, the motors of two motor blade units 2 are all connected to the power supply, after the switch switches on the power supplies of the two, two motors 21 drive their respective impellers 22 respectively to rotate, thereby generating negative pressure in the air duct 3, the air flow enters the air duct 3 from the air inlet end 11 on the outer shell, firstly passes through the filter cartridge, and then is discharged from the air outlet end 12 after passing through two motor blade units 2 along with the air duct, the foregoing process is performed continuously, the use mode is the same as that of a similar handheld wireless dust collector, and the suction force is at least equal to 1.5 times of that of a single motor blade unit with the same power and the same impeller size.
