Description

Technical Field

[0001] The utility model relates to the field of fan launchers, in particular to a fan launcher which is convenient for quick installation and fixing. Background Art

[0002] A fan transmitter serves as the signal transmitter in a fan remote control system, providing various command signals to the receiving end (typically the fan or fan controller). These command signals can include functions such as turning the fan on and off, adjusting the fan, and setting a timer. Existing fan transmitters consist of a top case, a bottom case, and a main control circuit board that provides command signals and remotely controls the fan. Batteries are installed inside the top and bottom cases to power the main control circuit board. Using a fan transmitter, users can conveniently control the fan remotely, improving convenience and comfort. Fan transmitters typically use infrared light-emitting diodes (IRLEDs) to emit modulated infrared light waves. When a command button on the transmitter is pressed, a command encoding circuit generates the required command signal, which modulates a carrier wave. This signal is then amplified by a driver circuit and ultimately transmitted by the IRLED. In practical applications, fan transmitters are typically used in conjunction with a fan receiver (or fan controller). Users can send command signals by pressing a button or adjusting a knob on the transmitter. The receiver decodes the signal and executes the corresponding operation. This remote control method not only improves the convenience of fan use but also allows for greater flexibility in fan placement, eliminating the constraints of power cords and switch positions.

[0003] Existing fan transmitters also have the following drawbacks: The top and bottom casings of existing fan transmitters are typically connected using screws. This is achieved by drilling holes in the top casing and tightening the screws. While this installation method is stable, it is cumbersome and inconvenient to install and remove. Replacing or repairing the inductor requires significant time and effort to remove and reinstall the screws, which also requires tools such as screwdrivers. This is very cumbersome, increasing maintenance costs and operational difficulty. The screw-based installation method is cumbersome and inconvenient for quick installation. Utility Model Content
