To the further description of the present invention, the inner surface and the side wall of the mounting groove are both provided with reinforcing ribs.

For further description of the present invention, the height of the housing is 70-80 mm; the height of the blades is 55-65 mm.

To the description of the present invention, the second air inlet is fan-shaped and six.

The utility model has the advantages that:

the utility model discloses a set up well pipe base under covering, set up the assembly axle again on well pipe base, the assembly axle is located the shell middle part, install motor group in the assembly axle outside, the axle core rotates to be connected in the assembly axle and one end connect the disc seat center drive disc seat and rotate, the iron-clad is glued the magnetism and is then fixed in the mounting groove, has shortened the length of axle core, motor group is located the mounting groove drive disc seat rotation of disc seat for turbine blade pivoted stability improves.

Detailed Description

The invention is further explained below with reference to the drawings:

as shown in fig. 1-3, a double-sided air inlet large-air-volume blower comprises a turbine shell 1, turbine blades 2, a motor assembly 3, an iron shell glue magnet 4 and a shaft core 5; the turbine shell 11 comprises an upper cover 11 and a lower cover 12 which are fixedly connected; a first air inlet 111 is formed in the center of the top surface of the upper cover 11; a middle pipe base 121 and a plurality of second air inlets 122 arranged around the middle pipe base 121 are arranged at the center of the bottom surface of the lower cover 12; an air outlet 101 is formed on one side of the lower cover 12 of the upper cover 11; the middle pipe base 121 protrudes above the lower cover 12; the center of the middle pipe base 121 is provided with an assembly shaft 123 extending upwards to the middle part of the shell 1; the assembly shaft 123 has a shaft hole 123-1 in the center; the turbine blade 2 is arranged in the middle of the shell 1; the turbine blade 2 comprises a disc seat 21 and blades 22 which are uniformly distributed and arranged on the outer side of the disc seat 21 in a spiral arrangement manner; the bottom of the disc seat 21 is provided with a mounting groove 211; the iron shell glue magnet 4 is arranged in the mounting groove 211; the motor assembly 3 is arranged outside the assembling shaft 123; the shaft core 5 is arranged in the shaft hole 123-1 through a bearing 501, and one end of the shaft core is fixedly connected with the center of the disc seat 21; wherein the motor assembly 3 comprises a PCBA board, a silicon steel sheet installed on the PCBA board and a coil installed on the silicon steel sheet.

The inner surface and the side wall of the mounting groove 211 are provided with reinforcing ribs; strengthen the strength of the disc seat 21 and improve the stability of the magnetic connection with the outside of the iron shell.
