Abstract
The utility model discloses a hedge trimmer with heat dissipation wind channel structure, a serial communication port, including brushless DC motor, the last motor radiator fan that is equipped with of brushless DC motor, the brushless DC motor outside is equipped with the wind channel structure, is equipped with power storehouse shell in brushless DC motor's outside. The utility model discloses a unique hedge trimmer motor wind channel structure for the air current that the motor fan produced takes away the heat that brushless DC motor and motor control system board work produced according to the direction of setting for, thereby furthest reduces the operating temperature of brushless DC motor and motor control system board.
Description
Technical Field
The utility model relates to a hedge trimmer with heat dissipation wind channel structure belongs to garden machine DC motor drive and heat dissipation technical field.
Background
Motor heat dissipation of motor drive hedge trimmer in the existing market mainly relies on motor fan heat dissipation, does not have heat dissipation air duct system, its characteristics: low cost, but poor heat dissipation effect. When the machine is loaded heavily or works for a long time, the motor is easily burnt out or is frequently stopped for protection, and the use effect and the working efficiency of operators are influenced.
Disclosure of Invention
The to-be-solved technical problem of the utility model is: the motor heat dissipation of the motor-driven hedge trimmer is improved, and the problem that the motor overheat protection is caused by heat generated by the high-power motor drive is solved, so that the motor-driven hedge trimmer is frequently stopped in the actual operation process, and the normal use is influenced is solved.
In order to solve the technical problem, the technical scheme of the utility model a hedge trimmer with heat dissipation wind channel structure is provided, a serial communication port, including brushless DC motor, the last motor radiator fan that is equipped with of brushless DC motor, the brushless DC motor outside is equipped with the wind channel structure, is equipped with the power storehouse shell in brushless DC motor's outside.
Preferably, the air duct structure is streamline, and the anti-backflow design is adopted to guide the wind direction.
Preferably, the power bin shell is provided with an air inlet and an air outlet, the power bin shell is internally provided with a motor control system board and a brushless direct current motor, the motor control system board is arranged on one side of the brushless direct current motor, and the power bin shell is fixedly connected with the front part of the motor control system board through a bolt.
The utility model discloses a unique hedge trimmer motor wind channel structure for the air current that the motor fan produced takes away the heat that brushless DC motor and motor control system board work produced according to the direction of setting for, thereby furthest reduces the operating temperature of brushless DC motor and motor control system board.
Drawings
Fig. 1 is a schematic structural view of the present invention;
fig. 2 is an installation schematic diagram of the present invention.
Detailed Description
In order to make the present invention more comprehensible, preferred embodiments are described in detail below with reference to the accompanying drawings.
As shown in fig. 1 and 2, a hedge trimmer with a heat dissipation air duct structure is characterized by comprising a power bin shell 8 provided with an air inlet 7 and an air outlet 6, a brushless direct current motor 3, the power bin shell 8 is arranged outside the brushless direct current motor 3, the power bin shell 8 is fixedly connected by a bolt 5, a motor heat dissipation fan 2 is arranged on the brushless direct current motor 3, an air duct structure 1 is arranged on the outer side of the brushless direct current motor 3, the air duct structure 1 is in a streamline and backflow prevention design and guides the wind direction, and the arrow mark in the figure indicates the wind direction.
The utility model discloses a unique design of wind channel structure 1 for the heat that the air current that the motor fan produced the work of brushless DC motor 3 and motor control system board 4 produced is taken away according to the direction of setting for, thereby furthest reduces the operating temperature of brushless DC motor 3 and motor control system board 4.
