Connecting assembly and axial-flow lampblack exhaust fan

Abstract

Provided are a connecting assembly and an axial-flow lampblack exhaust fan. The connecting assembly comprises a first connecting module and a second connecting module which are arranged correspondingly, wherein the first connecting module comprises a first connecting seat, a first connecting nail arranged on the first connecting seat, and a first connecting piece connected with the first connecting nail. The first connecting nail comprises a first outer column arranged on the first connecting seat in a protruding mode, a first middle column connected with the first outer column and a first inner column connected with the first middle column, wherein a resetting elastic part is connected onto the first inner column or the first middle column. The connecting assembly or the axial-flow lampblack exhaust fan facilitates power supply of a fan motor through the first connecting module and the second connecting module which are connected. When the fan motor is dismantled, a motor seat is separated from a curved tube axial air barrel, and the first connecting module is disconnected with the second connecting module. When the fan motor is installed, the motor seat is connected with the curved tube axial air barrel, powering-on of the first connecting module and the second connecting module can be achieved, and dismantling and maintenance of the fan and the fan motor are facilitated.

Description

technical field [0001] The invention relates to a component connection structure of a range hood, in particular to an electrical connection assembly and an axial flow fume fan with the electrical connection assembly. Background technique [0002] For an axial flow range hood or axial flow fan, in order to prevent the motor from being soaked in oil fume for a long time, the fan motor is placed outside the curved pipe axial flow fan cylinder, and the fan motor and the curved pipe are connected through the motor base. Installation and connection of axial fan. The power supply of the fan motor needs to be connected to the electric control circuit part of the range hood or an external power supply from the fan motor to obtain power. When disassembling or maintaining the fan motor, it is necessary to disconnect the wire of the external fan motor from the electric control circuit part of the range hood or the external power supply. A tool is required to untie the wire connections...

AI Technical Summary

Problems solved by technology

When installing the fan motor, it is necessary to lead the connecting wires from the inside of the fan motor to take power, which is inconvenient, cumbersome, time-consuming and labor-intensive to take the electrodes.

And the length of the leading wire is not easy to determine. If the wire is too long, it is not easy to place it, causing the wire to bend, which is easy to cause the wire to break. If the wire is short, it cannot be connected or the connection is unstable.
