[0042] Example
[0043] Smart pool robots are often used to clean and inspect pools. They can be used in conjunction with float devices. However, when the pool robot is connected to the float device, the float device will continue to be powered. Even when the pool robot is not working or sleeping, the float is still powered. This causes energy waste and affects the robot's battery life.
[0044] Based on this, this embodiment provides an intelligent power supply circuit, which is applied to a swimming pool robot. The intelligent power supply circuit can automatically disconnect the power supply of the float when the swimming pool robot is dormant, thereby saving energy and improving the robot's endurance.
[0045] See also Figure 1 , the circuit includes a control module 400, a logic trigger module 200, an electronic switch module 300 and at least one signal input module;
[0046] The input end of the at least one signal input module is electrically connected to the control module 400, and the output end of the at least one signal input module is electrically connected to the logic trigger module 200;
[0047] When the control module 400 inputs a first control signal to the logic trigger module 200 via the at least one signal input module, the logic trigger module 200 is used to input a first enable signal to the electronic switch module 300 to turn on the electronic switch module 300;
[0048] When the control module 400 inputs a second control signal to the logic trigger module 200 via the at least one signal input module, the logic trigger module 200 is configured to input a second enable signal to the electronic switch module 300 to turn off the electronic switch module 300 .
[0049] Exemplarily, the external load may be a float. When the swimming pool robot is in working state, the control module 400 inputs a first control signal to the logic trigger module 200 via at least one signal input module. At this time, the first control signal is at a high level. After receiving the first control signal, the logic trigger module 200 inputs a first enable signal to the electronic switch module 300. At this time, the first enable signal is at a high level. The fixed power supply in the electronic switch module 300 is turned on to power the external load, thereby powering on the external load. When the swimming pool robot is in a dormant state, the control module 400 identifies that the swimming pool robot is in a dormant state based on the working current / power value on the working circuit of the swimming pool robot, and then inputs a second control signal to the logic trigger module 200 via at least one signal input module. At this time, the second control signal is at a low level. The logic trigger module 200 inputs a second enable signal to the electronic switch module 300. At this time, the second enable signal is at a low level, and the fixed power supply to the external load is turned off, and the external load is powered off. Specifically, it will be combined with the following Figure 2 , Figure 3 And the digital logic function table is described in detail.
[0050] In one embodiment, the at least one signal input module includes a first signal input module 110, a second signal input module 120 and a third signal input module 130: the input end of the first signal input module 110 is electrically connected to the control module 400, and the output end of the first signal input module 110 is electrically connected to the logic trigger module 200; the first input end of the second signal input module 120 is electrically connected to the control module 400, the second input end of the second signal input module 120 is electrically connected to a fixed power supply, and the output end of the second signal input module 120 is electrically connected to the logic trigger module 200; the first input end of the third signal input module 130 is electrically connected to the control module 400, the second input end of the third signal input module 130 is electrically connected to a fixed power supply, and the output end of the third signal input module 130 is electrically connected to the logic trigger module 200.
[0051] In one embodiment, the logic trigger module 200 includes a logic trigger U1, a first pin of the logic trigger U1 is electrically connected to the output end of the third signal input module 130, a second pin of the logic trigger U1 is electrically connected to the output end of the second signal input module 120, and a sixth pin of the logic trigger U1 is electrically connected to the output end of the first signal input module 110.
[0052] See also Figure 2 and Figure 3, exemplarily, the control module 400 of the present application adopts MCU (Micro-controller Unit), and the logic trigger module 200 adopts the logic trigger U1, whose model can be NLV17SZ74USG. The control signal issued by the control module 400 is named according to the pins connected to the logic trigger U1 of each input module. The signal input to the first signal input module 110 is written as MCU_TO_U1_CLR#, the signal input to the second signal input module 120 is written as MCU_TO_U1_D, the signal input to the third signal input module 130 is written as MCU_TO_U1_CP, the first signal input module 110, the second signal input module 120 and the third signal input module 130 are connected to the MCU, and the MCU inputs a high level or a low level, thereby controlling the state of the circuit. In addition, the first signal input module 110, the second signal input module 120 and the third signal input module 130 are also connected to the CLR#, D, and CP of the logic trigger U1, respectively.
[0053] For example, please refer to Table 1, which shows a digital logic function table of the logic trigger U1.
[0054] Table 1:
[0055]
[0056]
[0057] In this embodiment, the PR# pin is connected to the fixed power input +5V_IN, so PR# is a fixed high level value, so it is only necessary to refer to the row where PR# is H in Table 1. The inputs of the CLR# pin (corresponding to the signal input by the first signal input module 110), the D pin (corresponding to the signal input by the second signal input module 120), and the CP pin (corresponding to the signal input by the third signal input module 130) are controlled by the control module 400. Among them, when the PR# pin is high level, the CLR# pin is low level, and there is no input to the D pin and the CP pin, the Q pin outputs a low level, that is, the logic trigger module 200 inputs a low level to the electronic switch module 300, and at this time, the fixed power supply is turned off to the power supply circuit of the external load. This situation corresponds to the dormant state of the swimming pool robot.
[0058] When the PR# pin is high, the CLR# pin is high, the D pin is high, and the CP pin is at a rising edge due to the presence of capacitor C1, the Q pin outputs a high level, the logic trigger module 200 inputs a high level to the electronic switch module 300, and the fixed power supply is turned on for the power supply circuit of the external load. This situation corresponds to the working state of the swimming pool robot.
[0059] In addition, when the PR# pin is at a high level, if the CLR# pin is at a high level, the D pin is at a low level, and the CP pin level is at a rising edge, then the Q pin outputs a low level, the logic trigger module 200 inputs a low level to the electronic switch module 300, and the fixed power supply cuts off the power supply circuit for the external load.
[0060] In one embodiment, the first signal input module 110 includes a first transistor Q1, the base of the first transistor Q1 is electrically connected to the control module 400, the collector of the first transistor Q1 is electrically connected to the sixth pin of the logic trigger U1, and the emitter of the first transistor Q1 is grounded. The first signal input module 110 also includes protection resistors R9 and R10, wherein the protection resistors play a role of protection and current limiting. When the base voltage of the first transistor Q1 reaches the conduction threshold of Q1, the first signal input module 110 can output a signal to the logic trigger U1.
[0061] When the input signal MCU_TO_U1_CLR# of the first signal input module 110 is at a high level, combined with Table 1, the signal value of the PR# input is always at a high level. Then at this time, when the CP and D terminals are connected to a fixed power supply of +5V (the MCU does not input signals to the third signal input module 130 and the second signal input module 120), the value of the second pin D input of the logic trigger U1 is a fixed high level. An electrolytic capacitor C1 is also provided between the first pin CP and the fixed power supply. Exemplarily, the value of the electrolytic capacitor C1 can be 100uF. When current passes through the electrolytic capacitor C1, due to the characteristic that the capacitor is charged first and then discharged, the first pin CP of the logic trigger U1 receives a rising edge signal (↑ in the table), and the fifth pin Q of the logic trigger U1 outputs a high level signal.
[0062] In one embodiment, the second signal input module 120 includes a second transistor Q2 and a first electrostatic protection unit E1, the base of the second transistor Q2 is electrically connected to the control module 400, the collector of the second transistor Q2 is electrically connected to the fixed power supply, and the emitter of the second transistor Q2 is grounded; the first end of the first electrostatic protection unit E1 is electrically connected to the collector of the second transistor Q2, and the second end of the first electrostatic protection unit E1 is grounded; the collector of the second transistor Q2 is also electrically connected to the second pin of the logic trigger U1. The second signal input module 120 also includes protection resistors R5, R6, R7, and R8. When the base voltage of the second transistor Q2 reaches the conduction threshold of Q2, the second signal input module 120 can output a signal to the logic trigger U1. Among them, the first electrostatic protection unit E1 can be an ESD diode, which can absorb and disperse ESD discharge by quickly conducting, directing current to the ground or other low potential points, thereby protecting electronic equipment from damage caused by electrostatic discharge (ESD) events, and can absorb and disperse low-energy ESD discharge.
[0063] In one embodiment, the third signal input module 130 includes a third transistor Q3 and a second electrostatic protection unit E2, the base of the third transistor Q3 is electrically connected to the control module 400, the collector of the third transistor Q3 is electrically connected to the fixed power supply, and the emitter of the third transistor Q3 is grounded; the first end of the second electrostatic protection unit E2 is electrically connected to the collector of the third transistor Q3, and the second end of the second electrostatic protection unit E2 is grounded; the collector of the third transistor Q3 is also electrically connected to the first pin of the logic trigger U1. The third signal input module 130 also includes protection resistors R1, R2, R3, and R4, and the second electrostatic protection unit E2 can be an ESD diode, which has the same function as above.
[0064] In one embodiment, the circuit further includes an electrolytic capacitor C1, the positive electrode of the electrolytic capacitor C1 is electrically connected to the collector of the third transistor Q3, the positive electrode of the electrolytic capacitor C1 is also electrically connected to the first pin of the logic trigger U1, and the negative electrode of the electrolytic capacitor C1 is grounded. The function of the electrolytic capacitor C1 has been explained above and will not be repeated here.
[0065] In addition, the circuit provided in this embodiment also includes protection resistors such as R11, R12, and R13, and filter capacitors such as C2 and C3, which play a filtering role between the power supply and the logic trigger chip U1, and electrostatic protection units such as D3, D4, and E3, which guide the static electricity in the circuit to the ground. It should be noted that the number, model, and position of the above components can be adjusted according to actual needs. Figure 2 For illustration purposes only.
[0066] In one embodiment, the circuit further includes a self-locking module 310;
[0067] The first input end of the self-locking module 310 is electrically connected to the control module 400 , the second input end of the self-locking module 310 is electrically connected to the logic trigger module 200 , and the output end of the self-locking module 310 is electrically connected to the control end of the electronic switch module 300 .
[0068] In one embodiment, the self-locking module 310 includes a first diode D1, a second diode D2 and a fourth transistor Q4, wherein the anode of the first diode D1 serves as the first input terminal of the self-locking module 310, and the cathode of the first diode D1 is electrically connected to the base of the fourth transistor Q4;
[0069] The anode of the second diode D2 serves as the second input terminal of the self-locking module 310, and the cathode of the second diode D2 is electrically connected to the base of the fourth transistor Q4;
[0070] The collector of the fourth transistor Q4 serves as the output end of the self-locking module 310, and the emitter of the fourth transistor Q4 is grounded;
[0071] The electronic switch module 300 includes a field effect transistor Q5, the gate of the field effect transistor Q5 serves as a control end of the electronic switch module 300, the source of the field effect transistor Q5 serves as an input end of the electronic switch module 300, and the drain of the field effect transistor Q5 serves as an output end of the electronic switch module 300.
[0072] Since the fifth pin Q of the logic trigger U1 outputs the signal U1_TO_ON / OFF to the positive electrode of the second diode D2, the base of the fourth transistor Q4 inputs a high-level signal, and the fourth transistor Q4 is turned on. At this time, the gate voltage of the field effect transistor Q5 (MOS tube) Q5 is also high, reaching the turn-on threshold of the MOS tube, and the field effect tube Q5 is turned on. The field effect tube Q5 is turned on as a switch tube and is set between the floating power supply +5V_IN and the power supply to the load, that is, the input terminal +5V of the float. When the field effect tube Q5 is turned on, the +5V power input terminal will input a power signal, so that the float is powered on and starts to work.
[0073] In the self-locking module 310 here, when the MCU_TO_ON / OFF signal received by the first diode D1 is at a high level, the first diode D1 is turned on, a high level signal is input to the base of the fourth transistor Q4, and the fourth transistor Q4 is turned on. At this time, even if the logic trigger U1 no longer inputs a high level signal to the second diode D2, the fourth transistor Q4 can still remain in the on state.
[0074] When the float is powered on and the pool robot is not working and is in sleep mode, the MCU identifies that the pool robot is in sleep mode based on the working current / power value on the circuit. For example, if the current current / current power value on the circuit is less than the minimum working current / minimum working power of the pool robot, the float needs to be powered off to save energy. If the TO_U1_CLR# input through the first signal input module is low at this time, the low-level signal is input to the positive electrode of the second diode D2, causing the fourth transistor Q4 and the field effect transistor Q5 to be unable to conduct, and the float device is powered off, thereby achieving power off in sleep mode. And by continuously inputting a low level through MCU_TO_ON / OFF, the pool machine is continuously maintained in sleep mode, and the float is controlled to be powered off.
[0075] It should be noted that the above embodiment only describes by way of example how to control the power on and off of the float. In fact, according to the output of the control module 400, the intelligent power supply circuit and the swimming pool robot provided in the embodiment of the present application can achieve more functions, which are not specifically limited here.
[0076] The intelligent power supply circuit provided in this embodiment can supply power to the floating device when the swimming pool robot is working normally, and can timely cut off the power to the floating device when the robot is dormant, thereby avoiding the continuous power consumption of the floating device when the swimming pool robot is dormant, which is beneficial to helping the swimming pool robot save power and extend the battery life of the swimming pool robot.
[0077] This embodiment also provides a swimming pool robot, which includes the intelligent power supply circuit as described in any of the above embodiments.
[0078] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
