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-blade handheld wireless vacuum cleaner, including an outer housing 1, an air inlet 2 and an air outlet 3 are provided on the outer housing 1, a motor 4 is further installed inside the outer housing 1, the motor 4 is connected to a storage battery to obtain electric energy to generate torque, and a power switch can be further provided on a circuit between the storage battery and the motor 4, and the storage battery can adopt a lithium battery which is the mainstream at present; more importantly, the output end of the motor 4 is also in power connection with at least two impellers 5, and the at least two impellers 5 are arranged on an airflow channel between the air inlet 2 and the air outlet 3, and because the motor 4 drives the two or more impellers 5 to rotate, airflow negative pressures generated by the two impellers can be mutually superposed; and similar to the structure of the similar wireless dust collector, the outer side of the air inlet 2 is also provided with a dust storage bin 6, and the dust storage bin 6 is also provided with an air inlet 7.
In this embodiment, through increasing a plurality of impellers 5 in the shell 1 and simultaneously with 4 power connection of motor for motor 4 can drive impeller 5 simultaneously and rotate, makes two impeller 5 operation of can establishing ties, thereby makes the stack appear in two impeller 5's vacuum, and then increases the intake, is favorable to promoting the suction of dust catcher, and need not to increase impeller 5 size, is favorable to controlling the whole volume size of wireless dust catcher.
Referring to fig. 1 again, as a preferred embodiment of the present invention, in order to facilitate the formation of the vacuum degree generated by the plurality of impellers 5 to overlap, the inventor improves the structure thereof, specifically, the output shaft can extend to the motor 4 at the front end and the rear end of the motor body, then directly designs the impellers 5 into two impellers with the same specification, and then respectively installs the two impellers 5 with the same specification on the output shafts at the front end and the rear end of the motor 4, so as to drive the two impellers 5 to rotate in the same direction by the motor 4; moreover, as mentioned above, the structure of the dust storage bin 6 of the wireless dust collector is the same as that of the similar dust collector in the market, so a filter 8 is also required to be installed in the dust storage bin 6 for filtering the dust entering from the air inlet 7, and the filter 8 is arranged between the air inlet 7 and the air inlet 2; still further, as shown in fig. 4, in order to further reduce the volume of the wireless vacuum cleaner, the handheld structure may also be configured to be foldable, specifically, the handle body 9 is installed on the outer casing 1, the handle body 9 is movably connected to the outer casing 1 through a hinge or a rotating column, the handle body 9 and the outer casing 1 can be formed into a folding structure through the hinge structure, and the storage battery can be installed inside the handle body 9 to save space.
