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.

The invention discloses an electric fan protection device. The electric fan protection device comprises a steering sleeve, a fixing block fixed to the middle point of one end face of the steering sleeve through a fixing piece, a main shaft arranged at the middle point of the end face of the fixing block and a fan blade fixedly arranged at the tail end of the tail end through a fastening piece; a containing groove is formed in the middle point of the steering sleeve, a steering column is installed inside the containing groove, a plurality of concave holes are formed in the side face of the steering column, a second steering shaft is arranged at the top end of the steering column and penetrates the top end of the steering sleeve to be fixedly connected through a bearing, and a connecting block is fixedly arranged at the top end of the second steering shaft; and an annular cavity is formed inside the steering sleeve, a plurality of groove holes communicated with the inner side of the annular cavity are formed inside the steering sleeve, and a limiting hole is formed inside the connecting position of each groove hole and the annular cavity.
Description
technical field [0001] The invention relates to the field of household appliances, in particular to an 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 provide...
