Abstract

The invention relates to an anti-falling ceiling fan. The anti-falling ceiling fan comprises fan blades, a connecting disc and a suspension rod, and is characterized in that the diameter of the lower end of the suspension rod is larger than the diameter of the upper end of the suspension rod, a plurality of grabbing devices are installed at the portion where the connecting disc is connected with the suspension rod and controlled by a motor installed in the connecting disc, and a grabbing control circuit is arranged in the suspension rod and formed in the mode that a voltage dependent resistor is connected with a ceiling fan motor in parallel to be connected with an electromagnet, a circuit protection circuit, a ceiling fan switch and an alternating current power source in series, grabbing circuits are arranged in the connecting disc, and each circuit is composed of a power source, a grabbing device motor and an armature switch in series. The anti-falling ceiling fan is reasonable in design, novel in structure and convenient to use, and the suspension rod can be grabbed through the grabbing devices when the ceiling fan falls; in addition, the appearance of the ceiling fan is not influenced, and the appearance is not influenced while the potential safety hazards are eliminated for a consumer.

Description

technical field [0001] The invention belongs to the field of daily life, and in particular refers to a ceiling fan for preventing fan blades from falling. Background technique [0002] At present, the ceiling fan is deeply loved by people because of the comfortable wind it produces, but the situation that the fan blades may fall due to the excessive use time has brought certain potential safety hazards to people's lives. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention provides a fall-preventing ceiling fan, which can eliminate the safety hazard of the ceiling fan falling and is safer to use. [0004] The technical scheme provided by the invention is: [0005] An anti-falling ceiling fan, including fan blades, a connecting plate and a suspender, is characterized in that: the diameter of the lower end of the suspender is larger than the diameter of the upper end, and a plurality of grabbing devices are installed at the connectio...
