Problems solved by technology
[0002] Electric fans are widely used household appliances in real life. They mainly use the motor to drive the fan blades to rotate to achieve the purpose of fanning. Most of the existing electric fans use the mode of fixed connection between the motor and the fan blade main shaft. However, this The protection of the connection mode is weak. For some young children with relatively weak safety awareness, they often use metal rods to insert into the electric fan cover to prevent the fan blades from rotating out of curiosity. When the fan blades cannot stop rotating, there is a great danger. At the same time, when the blocking force is strong, it is easy to cause the motor to burn out, which has great limitations.

Description
technical field [0001] The invention relates to the field of household appliances, in particular to a novel electric fan protection device. Background technique [0002] Electric fans are widely used household appliances in real life. They mainly use the motor to drive the fan blades to rotate to achieve the purpose of fanning. Most of the existing electric fans use the mode of fixed connection between the motor and the fan blade main shaft. However, this The protection of the connection mode is weak. For some young children with relatively weak safety awareness, they often use metal rods to insert into the electric fan cover to prevent the fan blades from rotating out of curiosity. Can not allow the fan blade to stop rotating at the same time, there is a greater danger, and when the blocking force is relatively large, it is easy to cause the motor to be burned, which has greater limitations. Contents of the invention [0003] The purpose of the present invention is to pr...
