Abluent tower fan is conveniently dismantled to wind wheel subassembly

The utility model provides an abluent tower fan is conveniently dismantled to wind wheel subassembly includes: base, motor and lower shaft coupling, the motor is fixed on the base, and lower shaft coupling is connected with the motor pivot, and lower shaft coupling includes the spacing tooth of joint -axis run down, the wind wheel subassembly includes wind wheel, last shaft coupling, hollow shaft coupling locking device from top to bottom, it includes shaft coupling cusp breach to go up the shaft coupling, go up the shaft coupling and pass through shaft coupling locking device from top to bottom, cup joint the lower extreme of fixing in the wind wheel pivot, shaft coupling locking device will go up shaft coupling and shaft coupling locking or unblock down from top to bottom, the spacing tooth of lower joint -axis run and mutual interlock of last shaft coupling cusp breach or separation, and when the wind wheel subassembly was connected with the motor pivot, electromotor drive wind wheel subassembly was rotatory, when the wind wheel subassembly separated with the motor pivot, the wind wheel subassembly also separated with tower fan body promptly. The wind wheel subassembly can independently be taken out tower fan, and this is external, conveniently cleans, gets rid of dust on it, has avoided the deposition to lead to the fact the air to pollute many times.
