Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a top view of the sanding head.
Fig. 3 is a side view of a sanding head.
Detailed Description
The present invention will be further described with reference to the accompanying drawings.
Referring to fig. 1 to 3, a wall surface sander with a controller disposed on a sanding head includes a sanding head 1 and a main handle, the polishing head comprises a machine shell 11, a motor, a fan blade 14, a protective disc 15 and a polishing disc 16, the motor is connected with a polishing disc 16 through a reduction box assembly 19, the polishing disc 16 is arranged below the protective disc 15, the fan blade 14 is arranged on the motor through an air guide ring 17, a rear cover 18 is arranged outside the fan blade 14, an air inlet is arranged on the rear cover 18, the lower end of the shell is provided with an air outlet, the reduction gearbox assembly 19 is arranged on the protective disc 15, the motor and the casing 11 are arranged on the reduction gearbox assembly 19, the controller 20 is positioned below the motor and arranged on the protective disc 15, the upper surface of the controller 20 is provided with a radiating fin 21, the heat radiating fins 21 are located below the air outlet, and the controller 20 is connected with the motor and is cooled by the fan blades.
In this embodiment, the motor is composed of a stator 12 and a rotor 13, the rear cover is located above the casing and connected with the casing, the protection disk is provided with a reduction gearbox assembly, the reduction gearbox assembly is provided with the motor, a fan blade, an air guide ring, the casing and the rear cover, the controller is arranged between the casing and the protection disk, and the surface of the controller is provided with a cooling fin which is located at an air outlet of the motor.
As shown in fig. 3, the upper arrow indicates the air inlet direction, and the lower arrow indicates the air outlet direction.
When the machine works, external air passes through the air inlet of the rear cover 18 and then is supplied to the lower part by the fan blade 14, and airflow flows through the stator cavity and the surface of the radiating fin 21; the heat generated by the motor and the controller 20 during operation is taken away, so as to achieve the purpose of cooling the motor and the controller 20 at the same time.
