Abstract: A single-tube blowing suction device, including a body, an airflow generation apparatus, a collection apparatus, and a blowing-suction tube. The airflow generation apparatus has an air inlet portion and an air outlet portion and is rotatably mounted on the body. The airflow generation apparatus rotates relative to the body to enable the single-tube blowing suction device to switch between a suction mode and a blowing mode. In the suction mode, the air inlet portion of the airflow generation apparatus is in fluid communication with a first end of the blowing-suction tube, and the air outlet portion is in fluid communication with a connection port of the collection apparatus. In the blowing mode, the air outlet portion is in fluid communication with the first end of the blowing-suction tube. In the single-tube blowing suction device of the present invention, one tube is used for both blowing and suction.

Abstract: A transmission device of a fan is provided. A central axis and an eccentric position of the transmission device are connected with a spindle and a connecting rod, respectively. The spindle is connected with a motor through gears. A first casing and a second casing of the transmission device are pivotally connected to each other. An accommodation hole of the second casing is provided with an elastic member and a press member to engage with an engaging recess of the first casing, such that the fan can be swung. When the user applies a force to change the angle of the fan, the press member is pressed by two press portions of the first casing to disengage from the engaging recess, such that the second casing can be turned relative to the first casing to prevent gear slipping or gear jumping of the motor, the gears, and the spindle.

Abstract: A cooling fan extending vertically to define a longitudinal axis, the cooling fan configured to blow air and mist therefrom. The cooling fan includes a base and multiple stacked duct housings with a fan housing therebetween, each of the duct housing being rotatably coupled to each other. The base includes a water tank associated with an atomizer, an axial flow fan, and a misting tube, the misting tube extending upward from the atomizer along the axis through an air duct defined by the duct housings. Each of the duct housings include an air outlet and a misting outlet to independently disperse air and mist therefrom to be mixed upon exiting the cooling fan. With this arrangement, each one of the duct housings is rotatable about the longitudinal axis relative to an adjacent one of the multiple duct housings to provide directional misted air flow from multiple selected positions.

Abstract: An electric fan includes a fan body having a fan shaft coupled to a fan motor. A fan motor bracket is connected to a fixing portion of the fan motor. A swivel shaft is coupled to the fan motor bracket. A sleeve is mounted around the swivel shaft and is coupled to an output shaft of a swivel motor. The sleeve includes an inner periphery having grooves. The swivel shaft receives an elastic element extending in a radial direction of the swivel shaft. A ball is mounted to an end of the elastic element. The ball is biased by the elastic element to be partially received in one of the grooves. If the fan body is impeded during the swiveling movement, the ball moves inward and compress the elastic element, disengaging the swivel shaft from the sleeve to reduce damage to the sleeve and the output shaft of the motor.
