Technical Field

[0001] The utility model relates to the technical field of electric heating blowers, in particular to an electric heating blower with a safety structure. Background Art

[0002] In the cold winter, electric blowers are often installed indoors to heat the room quickly and efficiently to make family members feel more comfortable. Existing electric blowers usually consist of a heating box, an electric heating wire, a blower, and an air outlet pipe. During use, the air in the heating box is heated by the electric heating wire, and then the heated air is blown out through the air outlet pipe by the blower.

[0003] For example: The utility model with application number CN202022635105.8 discloses an electric heating blower, specifically including a frame, a blower, an air outlet duct, a honeycomb barrel, a base plate, a lifting power device and a leakage detection device; the blower is fixed on the frame, the blower is connected to one end of the air outlet duct, the honeycomb barrel is located at the other end of the air outlet duct, and an electric heating wire is suspended in the hollow of the honeycomb barrel; the fixed end of the lifting power device is connected to the base plate, and the movable end of the lifting power device is connected to the frame; the end of the honeycomb barrel away from the blower is connected to a circular baffle, and the outer wall of the honeycomb barrel is provided with two grooves along the axial direction, and the opening directions of the two grooves are opposite, and the inner wall of the end of the air outlet duct where the honeycomb barrel is installed is provided with a guide bar, and the guide bar is inserted into the groove. The utility model has a novel design, and the honeycomb barrel is inserted into the air outlet duct along the guide bar. It is easy to operate and maintain, and the lifting power device can adjust the air outlet height of the electric heating blower.

[0004] However, as far as the current traditional electric blowers are concerned, during the use of electric blowers, some users will directly place them on the working heating box in order to dry clothes quickly, resulting in illegal operation, hindering the effective dissipation of hot air, and easily causing the heating box to overheat, causing fire and other safety hazards, which is dangerous. Utility Model Content

[0005] In view of this, the utility model provides an electric heating blower with a safety structure, which is provided with a control swing arm that can automatically prevent clothes from covering the heating box.

During the rotation of the first sprocket, the second sprocket is driven to rotate through the chain. The rotation of the second sprocket drives the connecting rotating shaft to rotate. During the rotation of the connecting rotating shaft, the control turntable is driven to rotate. During the rotation of the control turntable, the fixed column is driven to slide in the control slide groove, and then the control swing arm is driven to swing back and forth. The reciprocating swing of the control swing arm automatically sweeps off the clothes placed on the heating box and prevents the user from placing the clothes on the heating box.
