For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0028] The present application will be further described in detail below with reference to the accompanying drawings.

[0029] As Figure 1 shown, the present application provides a garbage can cleaning control circuit, which mainly includes three parts: a power input part, a main circuit and a control circuit.

[0030] The power input part includes three-phase power lines L1, L2, L3 and zero line N, which are connected to the system through a circuit breaker QF to provide power support for the entire system. The circuit breaker QF serves as a master switch and short-circuit protection to ensure the safety of the system.

[0031] The main circuit mainly includes three-phase asynchronous motors M1, M2, M3, which are used to drive the high-pressure water pump, the rotating disc and the spray head lifting mechanism, respectively. In the main circuit, thermal relays FR1, FR2 and FR3 are also provided, which are connected in series with the respective motors for monitoring the operating current of the motors. When the motors are overloaded, the circuit is automatically disconnected to protect the motors from damage. Contactors KM1, KM2, KM3 and KM4 control different functional components during the cleaning process, achieving precise control of the cleaning system.

[0032] The control circuit is divided into four main functional circuits: high-pressure water gun spray head circuit, rotating disc rotation circuit, spray head lifting mechanism circuit and spray head descending mechanism circuit.

[0033] High-pressure water gun spray head circuit: includes relay KM1 and motor M1. Contactor KM1 controls the opening and closing of contactor KM1, thereby controlling the start and stop of motor M1. Motor M1 provides high-pressure water flow for the cleaning system by driving the high-pressure water pump, enabling the spray head to spray high-pressure water for cleaning operations.

[0034] Rotating disc rotation circuit: includes relay KM2 and motor M2. Relay KM2 controls the opening and closing of contactor KM2, thereby controlling the start and stop of motor M2. Motor M2 is used to drive the rotating disc of the fixed garbage can to rotate, enabling the interior of the garbage can to receive high-pressure water flow for cleaning in all directions, ensuring uniformity of cleaning effect.

[0035] Spray head lifting mechanism circuit: includes relay KM3, motor M3 and time relay KT1. Relay KM3 controls the opening and closing of contactor KM3, thereby controlling the forward rotation of motor M3. When motor M3 rotates forward, it drives the spray head to move upwards, enabling the spray head to clean different height positions inside the garbage can. Time relay KT1 controls the length of time for which the spray head is lifted, ensuring that the spray head can rise to an appropriate position to cover all areas inside the garbage can that need to be cleaned.

[0036] Spray head descending mechanism circuit: includes relay KM4 and time relay KT2. Relay KM4 controls the opening and closing of contactor KM4, thereby controlling the operation of the spray head descending mechanism, enabling the spray head to return to the initial position after completing cleaning of the upper area of the garbage can for the second cleaning. Time relay KT2 controls the length of time for which the spray head descends, ensuring that the spray head can accurately return to the initial position.

[0037] Working principle:

[0038] System start-up: Turn on the three-phase power supply, close the circuit breaker QF, press the start button SB1, and the control circuit starts to work.

[0039] First stage - initial cleaning: After pressing SB1, the contactor KM1 in the high-pressure water gun nozzle circuit is powered on, controlling the motor M1 to start, and the high-pressure water pump starts to work, generating high-pressure water flow; at the same time, the contactor KM2 in the rotating disc rotation circuit is powered on, controlling the motor M2 to start, driving the rotating disc to rotate, and the garbage can fixed on the rotating disc starts to rotate. At this time, the nozzle is located at the bottom of the garbage can, and the bottom of the garbage can is cleaned for the first time.

[0040] Second stage - nozzle lifting: After the initial cleaning starts, the contacts 14-15 of the time relay KT1 are in the closed state, the contactor KM3 in the nozzle lifting mechanism circuit is powered on, controlling the motor M3 to start, and driving the nozzle to move upwards. As the nozzle rises, the garbage can inside is cleaned from bottom to top at different heights. During the nozzle rising process, the high-pressure water gun nozzle and the rotating disc continue to work, maintaining the rotation and cleaning of the garbage can.

[0041] Third stage - nozzle descending: After the nozzle rises to the predetermined height, the time relay KT1 timing ends, the contacts 14-15 are disconnected, the contacts 16-17 of the time relay KT1 are closed, the contactor KM4 in the nozzle descending mechanism circuit is powered on, controlling the nozzle descending mechanism to start, and making the nozzle gradually descend back to the initial position. During the nozzle descending process, the high-pressure water gun nozzle and the rotating disc continue to work, performing the second cleaning to ensure more thorough cleaning.

[0042] Fourth stage - complete cleaning: After the nozzle descends to the initial position, the contacts 18-19 of the time relay KT2 are disconnected, and the system completes a complete cleaning cycle. At this time, you can continue to start the next cleaning cycle or stop the system according to your needs after restarting SB1.

[0043] Safety protection: During the entire cleaning process, the thermal relays FR1, FR2, and FR3 in the main circuit continuously monitor the operating current of each motor. If the current of any motor becomes too large due to failure or overload, the corresponding thermal relay will automatically disconnect the circuit to protect the motor from damage. The circuit breaker QF provides short-circuit protection for the entire system, ensuring safe operation of the system.

[0044] The design of the garbage can cleaning control circuit fully considers the actual needs of garbage can cleaning, and through the coordinated work of the motor-driven high-pressure water pump, rotating disc rotation, and nozzle lifting device, it realizes the all-around cleaning of the inside and outside surfaces of the garbage can. The system uses automatic program control, which is easy to operate, has good cleaning effect, and is high in working efficiency, greatly reducing the working intensity of the cleaning personnel and improving the quality and efficiency of garbage can cleaning.

[0045] The specific embodiment is only an explanation of the utility model, and is not a limitation of the utility model, and a modification without creative contribution can be made to the embodiment according to needs by a person skilled in the art after reading the specification, but as long as the modification is within the scope of the claims of the utility model, the utility model is protected by the patent law.
