Detailed Description
The utility model will be described in further detail with reference to the accompanying drawings, which are simplified schematic drawings and only schematically illustrate the basic structure of the utility model, and the direction of the embodiment is based on the direction of fig. 1.
As shown in fig. 1 to 3, a touch power failure fan, including fan screen panel 1, flabellum 2, motor 3, controller 4, motor 3 is connected with the transmission of flabellum 2, motor 3 all sets up in fan screen panel 1 with flabellum 2, controller 4 is connected with motor 3 and stops with opening of control motor 3, still include touch-sensitive control module 5 of being connected with controller 4 electricity, be provided with conductive structure on the fan screen panel 1, conductive structure transmits the signal of telecommunication to touch-sensitive control module 5 to output motor 3 control signal to controller 4. After a human body touches the conductive structure, the conductive structure generates a changed electric signal and transmits the changed electric signal to the touch sensing control module 5, the controller 4 and the like which are electrically connected with the conductive structure, the controller 4 sends a control signal to the motor 3 according to the changed electric signal to control the starting and stopping of the motor 3, and therefore once a person touches the conductive structure on the fan mesh enclosure 1, the fan blades 2 can stop rotating immediately, and the use safety of the fan is improved.
The touch sensitive control module 5 comprises a metal connection pad 51, and the metal connection pad 51 is connected with the conductive structure.
The conductive structure is a conductive oil film layer formed on the fan mesh enclosure 1. The conductive oil film layer uniformly covers the fan mesh enclosure 1 so that a changed electric signal can be generated only by touching any position of the fan mesh enclosure 1, and the changed electric signal can control the starting and stopping of the motor 3 through the touch induction control module 5 and the controller 4. This provides greater security.
