Problems solved by technology
The existing key switch has only one slave control circuit, which can only control one slave load. If multiple slave functions are required to be independently controlled, for example, after the main control switch is closed, it is necessary to independently control lighting and other circuits, shaking head circuits, and water pump circuits. , negative ion circuit and other loads, the existing key switch cannot realize the above functions

The invention provides a control circuit. The control circuit is characterized in that one end of a first control circuit is connected with one end of an input power source, a second control circuit comprises a plurality of load modules which are connected in parallel, one end of the second control circuit is respectively connected with the end of the first control circuit and the end of the input power source, one end of a sampling module is connected with the other end of the first control circuit, the other end of the sampling module is connected with the other end of the input power source, the sampling module is used to generate sampling signals after the first control circuit is opened, one end of a switch module is connected with the other end of the second control circuit, the other end of the switch module is connected with the other end of the input power source, a control end of the switch module is connected with the end of the sampling module, and the switch module is switched on under control of the sampling signals. The control circuit can independently control a plurality of driven functions, and is simple in structure, reliable in performance and low in cost. The invention simultaneously provides an air fan.
Description
technical field [0001] The invention relates to the technical field of household appliances, in particular to a control circuit and a fan with the control circuit. Background technique [0002] At present, the master-slave control technology is relatively mature, but there are few master-slave control technologies with simple structure and reliable performance applied in the field of household appliances, and generally there is only one circuit for slave control, such as the piano key switch used on the electric fan, the existing piano key The switch has 3 master switches (wind speed gear) and 1 slave switch. The master switch is used to control the motor gear. After any master switch is activated, the mechanical linkage connects the slave switch (shake gear) To the main power supply, if the slave switch is closed, the load such as the oscillating head motor will be connected to the main power supply, and the oscillating head action will be started, thereby realizing master-...
