[0018] Compared with the prior art, the utility model has the following beneficial effects: the utility model provides an air compressor power supply system with a dual carbon-based capacitor structure, and the air compressor power supply system with a dual carbon-based capacitor structure includes a first power supply module, a first carbon-based capacitor module, a control module, and a second power supply module. When the air compressor is started, the control module outputs a first start signal, and the first small current circuit is connected based on the first start signal. Thus, the first power supply module can supply power to the air compressor. After delaying the first start time, the control module can output a second start signal and a third start signal. The first large current circuit is connected based on the second start signal, and the first capacitor circuit is connected based on the third start signal. At this time, the first power supply module can supply power to the air compressor through the first small current circuit and the first large current circuit, and the first power supply module can supply power to the first carbon-based capacitor through the first capacitor circuit. If the instantaneous working power of the air compressor is greater than the first set value, the first carbon-based capacitor module can release the electric energy within a certain period of time. Moreover, if the instantaneous working power of the air compressor is less than the first set value, the first carbon-based capacitor module absorbs the electric energy of the first power supply module. Therefore, the first carbon-based capacitor can effectively increase the range of instantaneous output power of the first power supply module, and the air compressor can maintain a stable working state.

[0019] When the power of the air compressor is greater than the first set value, the control module is used to output a fourth start-up signal, and the second low-current circuit is connected based on the fourth start-up signal. Thus, the second power supply module can supply power to the air compressor. After delaying the second start-up time, the control module is used to output a fifth start-up signal, and the second high-current circuit is connected based on the fifth start-up signal. At this time, the second power supply module can supply power to the air compressor through the second low-current circuit and the second high-current circuit. Therefore, when the working power of the air compressor increases or multiple air compressors work at the same time, the air compressor power supply system with a dual-carbon-based capacitor structure can supply power to the air compressor through two power supply modules. The air compressor power supply system with a dual-carbon-based capacitor structure can increase the output voltage so that the voltage output by the air compressor power supply system with a dual-carbon-based capacitor structure matches the working power of the air compressor, so that the air compressor maintains a stable working state.

[0020] When the power of the air compressor is less than the second set value, the control module outputs the first disconnection signal and the second disconnection signal. The second large current circuit is turned off based on the first disconnection signal, and the second capacitor circuit is turned off based on the second disconnection signal. After delaying the first disconnection time, the control module outputs the third disconnection signal, and the second small current circuit is turned off based on the third disconnection signal. That is, when the working power of the air compressor is reduced or multiple air compressors are turned off, the air compressor power supply system with a dual carbon-based capacitor structure can gradually disconnect the second power supply module. Furthermore, the air compressor power supply system with a dual carbon-based capacitor structure can reduce the output voltage so that the voltage output by the air compressor power supply system with a dual carbon-based capacitor structure matches the working power of the air compressor, so that the air compressor can maintain a stable working state. In the air compressor power supply system with a dual carbon-based capacitor structure, if the working power of the air compressor changes, the air compressor power supply system with a dual carbon-based capacitor structure can adjust the output voltage through the first carbon-based capacitor module and the second power supply module. Thus, the voltage output by the air compressor power supply system with a dual carbon-based capacitor structure matches the working power of the air compressor. Since the air compressor can receive a stable driving voltage, the air compressor can work stably at any working power, which effectively solves the technical problem that the existing air compressor is difficult to maintain a stable working state for a long time.

[0029] In the figures, structurally similar elements are denoted by the same reference numerals.

[0030] Please refer to Figure 1and Figure 2 The utility model provides an air compressor power supply system 10 with a dual carbon-based capacitor structure, and the air compressor power supply system 10 with a dual carbon-based capacitor structure includes a first power supply module 11, a first carbon-based capacitor module 12, a first control module 13, a first switch module 14, a second power supply module 15, a second switch module 16, and an output module 17. The first power supply module 11 is used to generate a first power supply voltage, and the first carbon-based capacitor module 12 is used to perform energy storage operation on the first power supply voltage.

[0031] Please refer to Figure 1 and Figure 2 , the first switch module 14 includes a first small current circuit 141, a first large current circuit 142, and a first capacitor circuit 143. The input end of the first small current circuit 141 is connected to the first power supply module 11, and the output end of the first small current circuit 141 is connected to the output module 17. The input end of the first large current circuit 142 is connected to the first power supply module 11, and the output end of the first large current circuit 142 is connected to the output module 17. The input end of the first capacitor circuit 143 is connected to the first power supply module 11, and the output end of the first capacitor circuit 143 is connected to the output module 17 and the first carbon-based capacitor module 12. The control module 13 can output a first start signal, the first small current circuit 141 can be turned on based on the first start signal, and the first switch module 14 can power the air compressor through the first small current circuit 141. After delaying the first start time, the control module 13 can output a second start signal and a third start signal. Among them, the first start time can be 2 seconds. The first large current circuit 142 can be turned on based on the second start signal, at which time the first switch module 14 can power the air compressor through the first large current circuit 142, and the first capacitor circuit 143 can be turned on based on the third start signal. When the air compressor starts, the first switch module 14 first powers the air compressor through the first small current circuit 141. After delaying the first start time, the first switch module 14 then powers the air compressor through the first large current circuit 142. This driving method can make the startup of the air compressor more stable, and after the air compressor works normally, the first switch module 14 only powers the air compressor through the first large current circuit 142.

[0032] Moreover, the first power supply module 11 can supply power to the first carbon-based capacitor 121 through the first capacitor circuit 143. When the first power supply module 11 supplies power to the air compressor, if the instantaneous working power of the air compressor is greater than the first set value, the first carbon-based capacitor module 12 can release the electric energy within a certain period of time. Moreover, if the instantaneous working power of the air compressor is less than the first set value, the first carbon-based capacitor module 12 absorbs the electric energy of the first power supply module 11. Therefore, the first carbon-based capacitor 121 can effectively increase the range of the instantaneous output power of the first power supply module 11.

[0033] Please refer to Figure 1 and Figure 2 , the second power supply module 15 is used to generate a second power supply voltage. The air compressor power supply system 10 with a dual carbon-based capacitor structure includes a second carbon-based capacitor module 19, which is used to store energy for the second power supply voltage. The second switch module 16 includes a second small current circuit 161, a second large current circuit 162, and a second capacitor circuit 163. The input end of the second small current circuit 161 is connected to the second power supply module 15, and the output end of the second small current circuit 161 is connected to the output module 17. The input end of the second large current circuit 162 is connected to the second power supply module 15, and the output end of the second large current circuit 162 is connected to the output module 17. The input end of the second capacitor circuit 163 is connected to the first power supply module 11, and the output end of the second capacitor circuit 163 is connected to the output module 17 and the second carbon-based capacitor module 19. When the power of the air compressor is greater than the first set value, the control module 13 can output a fourth start signal, and the second small current circuit 161 is turned on based on the fourth start signal. After delaying the second start time, the control module 13 can output a fifth start signal and a sixth start signal. Among them, the second startup time can be 2 seconds. The second high current circuit 162 is turned on based on the fifth start signal, and the second capacitor circuit 163 is turned on based on the sixth start signal. At this time, the second power supply module 15 can power the air compressor through the second low current circuit 161 and the second high current circuit 162. When the power of the air compressor is greater than the first set value, the second switch module 16 first powers the air compressor through the second low current circuit 161. After delaying the first startup time, the first switch module 14 then powers the air compressor through the second high current circuit 162. This power supply method can make the voltage of the air compressor increase steadily, and after the air compressor works normally, the second power supply module 15 only powers the air compressor through the second high current circuit 162.

[0034] Therefore, when the working power of the air compressor increases or multiple air compressors work at the same time, the air compressor power supply system 10 with a dual carbon-based capacitor structure can power the air compressor through two power supply modules. The air compressor power supply system 10 with a dual carbon-based capacitor structure can increase the output voltage so that the voltage output by the air compressor power supply system 10 with a dual carbon-based capacitor structure matches the working power of the air compressor, and then the air compressor maintains a stable working state. In addition, the second power supply module 15 can power the second carbon-based capacitor module 19 through the second capacitor circuit 163. When the working power of the air compressor increases, if the power supply voltage of the air compressor is insufficient, the air compressor is always in a low-voltage working state. Therefore, it is difficult for the air compressor to work stably.

[0035] Please refer to Figure 1 and Figure 2, the output module 17 can convert the first power supply voltage and the second power supply voltage of DC into the output voltage of AC, and the output module 17 can output the output voltage to the air compressor or the air compressor unit 18. When the power of the air compressor is less than the second set value, the control module 13 can output the first disconnection signal and the second disconnection signal. The second large current circuit 162 is turned off based on the first disconnection signal, and the second capacitor circuit 163 is turned off based on the second disconnection signal. After delaying the first disconnection time, the control module 13 can output the third disconnection signal, and the second small current circuit 161 is turned off based on the third disconnection signal. Among them, the first disconnection time can be 2 seconds. When the power of the air compressor is less than the second set value, the second switch module 16 first turns off the second large current circuit 162 and the second capacitor circuit 163. At this time, the second switch module 16 can also supply power to the air compressor through the second small current circuit 161. After delaying the first disconnection time, the first switch module 14 turns off the second small current circuit 161. This way of gradually disconnecting the second power supply module 15 can steadily reduce the voltage of the air compressor.

[0036] When the working power of the air compressor is reduced or multiple air compressors are shut down, the air compressor power supply system 10 with a dual carbon-based capacitor structure can gradually disconnect the second power supply module 15. Furthermore, the air compressor power supply system 10 with a dual carbon-based capacitor structure can reduce the output voltage so that the voltage output by the air compressor power supply system 10 with a dual carbon-based capacitor structure matches the working power of the air compressor, and the air compressor maintains a stable working state. Moreover, when the first power supply module 11 and the second power supply module 15 supply power to the air compressor, if the instantaneous working power of the air compressor is less than the second set value, the first carbon-based capacitor module 12 can recover the electric energy of the first power supply module 11 within a certain period of time, and the second carbon-based capacitor module 19 can recover the electric energy of the second power supply module 15 within a certain period of time. Moreover, when the instantaneous working power of the air compressor is greater than the second set value, the first carbon-based capacitor module 12 can also release electric energy. Therefore, the first carbon-based capacitor 121 and the second carbon-based capacitor 191 can effectively increase the range of the instantaneous output power of the first power supply module 11 and the second power supply module 15.

[0037] Please refer to Figure 1 and Figure 2, when the air compressor is turned off, the control module 13 outputs the fourth disconnection signal and the fifth disconnection signal. The first large current circuit 142 is turned off based on the fourth disconnection signal, and the first capacitor circuit 143 is turned off based on the fifth disconnection signal. After delaying the second disconnection time, the control module 13 outputs the sixth disconnection signal, and the first small current circuit 141 is turned off based on the sixth disconnection signal. Among them, the second disconnection time can be 2 seconds. When the air compressor is turned off, the first switch module 14 first turns off the first large current circuit 142 and the first capacitor circuit 143. At this time, the first switch module 14 can also power the air compressor through the first small current circuit 141. After delaying the second disconnection time, the first switch module 14 turns off the first large current circuit 142 again. This gradual power-off method can make the shutdown of the air compressor more stable.

The second carbon-based capacitor module 19 can drive a large current through a small current, thereby improving the safety of the air compressor power supply system 10 with a dual carbon-based capacitor structure. When the voltage value of the second carbon-based capacitor 191 is greater than or equal to the second set voltage, the first start switch SA1-1 is disconnected, the second start switch SA1-2 is closed, and the second external power supply 192 is used to power the drive battery 123. Therefore, the drive battery 123 always has enough power to drive the second capacitor module relay 11DJ. The function of the second carbon-based capacitor module 19 is the same as that of the first carbon-based capacitor module 12 , and the working principle of the second carbon-based capacitor module 19 is also the same as that of the first carbon-based capacitor module 12 .

[0065] The working principle of the utility model is as follows: when the air compressor power supply system 10 with a dual carbon-based capacitor structure is started, the first control unit 131 outputs a first start signal, and the control end of the first low-current contactor 1DJB receives the first start signal. The first low-current contactor 1DJB can be turned on based on the first start signal, so that the first low-current circuit 141 is turned on, and the first switch module 14 transmits the first power supply voltage to the output module 17 through the first low-current circuit 141. After the first low-current contactor 1DJB is turned on, the first start time is delayed, and the second control unit 132 outputs a second start signal. The third control unit 133 outputs a third start signal, and the control end of the first high-current contactor 1DJA receives the second start signal. The first high-current contactor 1DJA can be turned on based on the second start signal, so that the first high-current circuit 142 is turned on, and the first switch module 14 transmits the first power supply voltage to the output module 17 through the first high-current circuit 142. At the same time, the control end of the first capacitor circuit contactor 2DJ receives the third start signal. The first capacitor circuit contactor 2DJ can be turned on based on the third start signal, so that the first capacitor circuit 143 is turned on. The first switch module 14 transmits the first power supply voltage to the first carbon-based capacitor module 12 through the first capacitor circuit 143 .

[0066] When the power of the air compressor is greater than the first set value, the fourth control unit 134 outputs a fourth start signal. The control end of the second low-current contactor 3DJB receives the fourth start signal, and the second low-current contactor 3DJB is turned on based on the fourth start signal. Thus, the second low-current circuit 161 is turned on, and the second switch module 16 transmits the second power supply voltage to the output module 17 through the second low-current circuit 161. After the second low-current contactor 3DJB is turned on, the second start time is delayed. The fifth control unit 135 outputs the fifth start signal, and the sixth control unit 136 outputs the sixth start signal. The control end of the second high-current contactor 3DJA receives the fifth start signal, and the second high-current contactor 3DJA can be turned on based on the fifth start signal. Thus, the second high-current circuit 162 is turned on, and the second switch module 16 transmits the second power supply voltage to the output module 17 through the second high-current circuit 162. At the same time, the control end of the second capacitor circuit contactor 4DJ receives the sixth start signal. The second capacitor circuit contactor 4DJ can be turned on based on the sixth start signal, so that the second capacitor circuit 163 is turned on, and the second switch module 16 transmits the second supply voltage to the second carbon-based capacitor module 19 through the second capacitor circuit 163. Moreover, the air compressor power supply system 10 with a dual carbon-based capacitor structure is provided with a first carbon-based capacitor module 12. When the first power supply module 11 supplies power to the air compressor, if the instantaneous working power of the air compressor is greater than the first set value, the first carbon-based capacitor module 12 can release the electric energy within a certain period of time. Moreover, if the instantaneous working power of the air compressor is less than the first set value, the first carbon-based capacitor module 12 absorbs the electric energy of the first power supply module 11. Therefore, the first carbon-based capacitor 121 can effectively increase the range of the instantaneous output power of the first power supply module 11.

[0067] When the first power supply module 11 and the second power supply module 15 supply power to the air compressor, the instantaneous working power of the air compressor may fluctuate around the second set value. If the instantaneous working power of the air compressor is greater than the second set value, the first carbon-based capacitor module 12 can release the electric energy within a certain period of time. And, if the instantaneous working power of the air compressor is less than the second set value, the first carbon-based capacitor module 12 absorbs the electric energy of the first power supply module 11, and the second carbon-based capacitor module 19 absorbs the electric energy of the second power supply module 15. Therefore, the first carbon-based capacitor 121 and the second carbon-based capacitor 191 can effectively increase the range of the instantaneous output power of the first power supply module 11 and the second power supply module 15.

[0068] When the power of the air compressor is less than the second set value, the fifth control unit 135 outputs a first disconnection signal. The sixth control unit 136 outputs a second disconnection signal, and the control end of the second high-current contactor 3DJA receives the first disconnection signal. The second high-current contactor 3DJA can be disconnected based on the first disconnection signal, so that the second high-current circuit 162 is disconnected. At the same time, the control end of the second capacitor circuit contactor 4DJ receives the second disconnection signal, and the second capacitor circuit contactor 4DJ can be disconnected based on the second disconnection signal, so that the second capacitor circuit 163 is disconnected. After the second high-current contactor 3DJA is disconnected, the first disconnection time is delayed. The fourth control unit 134 outputs a third disconnection signal, and the control end of the second low-current contactor 3DJB receives the third disconnection signal, and the second low-current contactor 3DJA can be disconnected based on the third disconnection signal, so that the second low-current circuit 161 is disconnected.

[0069] When the air compressor is turned off, the second control unit 132 outputs a fourth disconnection signal, the third control unit 133 outputs a fifth disconnection signal, and the control end of the first high-current contactor 1DJA receives the fourth disconnection signal. The first high-current contactor 3DJA can be disconnected based on the fourth disconnection signal, so that the first high-current circuit 142 is disconnected. At the same time, the control end of the first capacitor circuit contactor 2DJ receives the fifth disconnection signal. The first capacitor circuit contactor 2DJ can be disconnected based on the fifth disconnection signal, so that the first capacitor circuit 143 is disconnected. After the first high-current contactor 1DJA is disconnected, the second disconnection time is delayed, and the first control unit 131 outputs a sixth disconnection signal. The control end of the first low-current contactor 1DJB receives the sixth disconnection signal, and the first low-current contactor 1DJB can be disconnected based on the sixth disconnection signal, so that the first low-current circuit 141 is disconnected.

[0070] In the first carbon-based capacitor module 12, when the voltage value of the first carbon-based capacitor 121 is less than the first set voltage, the first start switch SA1-1 is in an open state. The second start switch SA1-2 is in a closed state, and the drive battery 123 outputs the drive signal to the control end of the first capacitor module relay 10DJ. The first capacitor module relay 10DJ can be turned on based on the drive signal, so that the first external power supply 122 can supply power to the first carbon-based capacitor 121. When the voltage value of the first carbon-based capacitor 121 is greater than or equal to the second set voltage, the first start switch SA1-1 is in an open state, and the second start switch SA1-2 is in a closed state, so that the first external power supply 122 supplies power to the drive battery 123.

[0071] The utility model provides an air compressor power supply system with a dual carbon-based capacitor structure, and the air compressor power supply system with a dual carbon-based capacitor structure includes a first power supply module, a first carbon-based capacitor module, a control module, and a second power supply module. When the air compressor is started, the control module outputs a first start signal, and the first small current circuit is connected based on the first start signal. Thus, the first power supply module can supply power to the air compressor. After delaying the first start time, the control module can output a second start signal and a third start signal. The first large current circuit is connected based on the second start signal, and the first capacitor circuit is connected based on the third start signal. At this time, the first power supply module can supply power to the air compressor through the first small current circuit and the first large current circuit, and the first power supply module can supply power to the first carbon-based capacitor through the first capacitor circuit. If the instantaneous working power of the air compressor is greater than the first set value, the first carbon-based capacitor module can release the electric energy within a certain period of time. Moreover, if the instantaneous working power of the air compressor is less than the first set value, the first carbon-based capacitor module absorbs the electric energy of the first power supply module. Therefore, the first carbon-based capacitor can effectively increase the range of instantaneous output power of the first power supply module, and the air compressor can maintain a stable working state.

[0072] When the power of the air compressor is greater than the first set value, the control module is used to output a fourth start-up signal, and the second low-current circuit is connected based on the fourth start-up signal. Thus, the second power supply module can supply power to the air compressor. After delaying the second start-up time, the control module is used to output a fifth start-up signal, and the second high-current circuit is connected based on the fifth start-up signal. At this time, the second power supply module can supply power to the air compressor through the second low-current circuit and the second high-current circuit. Therefore, when the working power of the air compressor increases or multiple air compressors work at the same time, the air compressor power supply system with a dual-carbon-based capacitor structure can supply power to the air compressor through two power supply modules. The air compressor power supply system with a dual-carbon-based capacitor structure can increase the output voltage so that the voltage output by the air compressor power supply system with a dual-carbon-based capacitor structure matches the working power of the air compressor, so that the air compressor maintains a stable working state.

[0073] When the power of the air compressor is less than the second set value, the control module outputs the first disconnection signal and the second disconnection signal. The second large current circuit is turned off based on the first disconnection signal, and the second capacitor circuit is turned off based on the second disconnection signal. After delaying the first disconnection time, the control module outputs the third disconnection signal, and the second small current circuit is turned off based on the third disconnection signal. That is, when the working power of the air compressor is reduced or multiple air compressors are turned off, the air compressor power supply system with a dual carbon-based capacitor structure can gradually disconnect the second power supply module. Furthermore, the air compressor power supply system with a dual carbon-based capacitor structure can reduce the output voltage so that the voltage output by the air compressor power supply system with a dual carbon-based capacitor structure matches the working power of the air compressor, so that the air compressor can maintain a stable working state. In the air compressor power supply system with a dual carbon-based capacitor structure, if the working power of the air compressor changes, the air compressor power supply system with a dual carbon-based capacitor structure can adjust the output voltage through the first carbon-based capacitor module and the second power supply module. Thus, the voltage output by the air compressor power supply system with a dual carbon-based capacitor structure matches the working power of the air compressor. Since the air compressor can receive a stable driving voltage, the air compressor can work stably at any working power, which effectively solves the technical problem that the existing air compressor is difficult to maintain a stable working state for a long time.
