The chip IC1 controls the motor driving module to cover: the fifteenth pin of the chip IC1 outputs a low level to control the emitter electrode of the triode Q3 to be conducted with the collector electrode, the tenth pin of the chip IC1 outputs a high level to control the collector electrode of the triode Q4 to be conducted with the emitter electrode, current enters the motor M+ from the VDD through the triode Q3 and then reaches GND from the motor M-through the triode Q4, and the cover of the garbage can is opened;
The chip IC1 controls the motor driving module to close the cover: the eighth pin of the chip IC1 outputs a low level to control the emitter electrode of the triode Q2 to be conducted with the collector electrode, the ninth pin of the chip IC1 outputs a high level to control the collector electrode of the triode Q5 to be conducted with the emitter electrode, current enters the motor M-from the VDD through the triode Q2 and then passes through the triode Q5 to the GND from the motor M+ so as to realize the closing of the garbage can.
Referring to fig. 1 to 7, a second embodiment of the present utility model is as follows:
A garbage can comprises the switch cover control circuit capable of adjusting the sensing distance.
In summary, according to the switch cover control circuit and the garbage can with the adjustable sensing distance, the infrared emission module, the infrared receiving module, the signal amplifying module, the key module, the main control module, the motor driving module and the motor are arranged, when a shielding object blocks and reflects an optical signal sent by the infrared emission module, the infrared receiving module and the signal amplifying module convert the optical signal into an analog voltage signal and send the analog voltage signal to the main control module, the main control module compares the voltage signal with a preset threshold voltage, if the voltage signal is larger than the threshold voltage, the main control module controls the motor driving module to control the switch cover of the garbage can, otherwise, if the analog voltage signal is smaller than the threshold voltage, the main control module indicates that no person needs to put garbage; setting a key module, entering an adjusting induction mode when the key module works, stopping a hand at a desired induction distance in the adjusting induction mode, converting a light signal reflected at the moment into an analog voltage signal through an infrared receiving module and a signal amplifying module, transmitting the analog voltage signal to a main control module, storing the voltage signal into a new threshold voltage by the main control module, and finishing adjustment of the distance; compared with a traditional dustbin with a mechanical mechanism for opening and closing the cover, the control circuit for opening and closing the cover omits the step of contacting the dustbin, is convenient and labor-saving, and reduces the risks of cross contamination and disease transmission; because the height of the user is inconsistent with the habit of garbage disposal, the requirement on the sensing distance is different, and the scheme provides the function of adjusting the sensing distance, so that the use experience of the user can be improved.
