In the intelligent floor sweeper and floor washer products in the related art, the electrolyzed water module cannot be detached and cleaned, and the electrode plates cannot be well utilized, so that the service life of the products is shortened.

In order to solve the above problems, the present disclosure provides an electrode commutation circuit, where the electrode commutation circuit includes a power supply module, a commutation module, an electrode and a control module, the commutation module is respectively electrically connected to the power supply module, the control module and the electrode, the commutation module includes a first control branch and a second control branch that are arranged in parallel, the first control branch includes a first transistor and a second transistor that are connected in series, the second control branch includes a third transistor and a fourth transistor that are connected in series, the first transistor and the third transistor are electrically connected to a positive terminal of the power supply module, the second transistor and the fourth transistor are electrically connected to a negative terminal of the power supply module, the electrode includes a first electrode and a second electrode, the first electrode is electrically connected between the first transistor and the second transistor, and the second electrode is electrically connected between the third transistor and the fourth transistor. In the disclosure, the transistors are used as switch units in the switching module, the control module controls the on and off of the transistors, and the anode and cathode directions of the first electrode and the second electrode are changed, so that the electrode plate is prevented from scaling due to long-term use. The electrode reversing circuit is simple in structure, large and expensive devices such as relays are not needed, and the electrode reversing circuit has the advantages of being small in size, high in reliability and the like.

According to an exemplary embodiment, as shown in fig. 1, 2, 5 and 8, an electrode commutation circuit is shown, which comprises a power supply module 1, a commutation module 3, an electrode 4 and a control module 2, the commutation module 3 being electrically connected to the power supply module 1, the control module 2 and the electrode 4, respectively. The power supply module 1 is electrically connected with the commutation module 3 to supply power to the commutation module 3 and further to supply power to the electrode 4. The control module 2 is electrically connected with the commutation module 3, and the control module 2 controls the on/off of each transistor in the commutation module 3 to change the current path connected with the electrode 4. The reversing module 3 is electrically connected with the electrode 4, and the circuit flow direction output to the electrode 4 by the power supply module 1 through the reversing module 3 changes, so that the polarity of the electrode 4 is changed.

In this embodiment, as shown in fig. 2, fig. 5 and fig. 8, the commutation module 3 includes a first control branch and a second control branch that are arranged in parallel, the first control branch includes a first transistor 31 and a second transistor 32 that are connected in series, the second control branch includes a third transistor 33 and a fourth transistor 34 that are connected in series, the first transistor 31 and the third transistor 33 are electrically connected to the positive terminal of the power supply module 1, and the second transistor 32 and the fourth transistor 34 are electrically connected to the negative terminal of the power supply module 1. The electrode 4 includes a first electrode 41 and a second electrode 42, the first electrode 41 is electrically connected between the first transistor 31 and the second transistor 32, and the second electrode 42 is electrically connected between the third transistor 33 and the fourth transistor 34. Since the polarities of the first electrode 41 and the second electrode 42 may be changed according to the conduction of different current paths, the connection manner thereof has no influence on the polarities of the electrodes, for example, the first electrode 41 may be connected between the third transistor 33 and the fourth transistor 34, and the second electrode may be connected between the first transistor 31 and the second transistor 32, which does not influence the implementation of the technical solution described in this embodiment.

In this embodiment, the transistors are used as the switching units in the commutation module, and the control module 2 controls the on and off of the plurality of transistors, so that different current paths can be formed among the power supply module, the commutation module, and the electrodes, thereby changing the polarities of the first electrode and the second electrode, and preventing the first electrode and the second electrode from maintaining one polarity for a long time to cause dirt accumulation thereon.

In an exemplary embodiment, as shown in fig. 1, 2, 5 and 8, an electrode commutation circuit is shown, the electrode commutation circuit comprising a power supply module 1, a commutation module 3, an electrode 4 and a control module 2, the commutation module 3 being electrically connected to the power supply module 1, the control module 2 and the electrode 4, respectively. The commutation module 3 comprises a first control branch and a second control branch which are arranged in parallel, the first control branch comprises a first transistor 31 and a second transistor 32 which are connected in series, the second control branch comprises a third transistor 33 and a fourth transistor 34 which are connected in series, the first transistor 31 and the third transistor 33 are electrically connected with a positive terminal of the power supply module 1, the second transistor 32 and the fourth transistor 34 are electrically connected with a negative terminal of the power supply module 1, the electrode 4 comprises a first electrode 41 and a second electrode 42, the first electrode 41 is electrically connected between the first transistor 31 and the second transistor 32, and the second electrode 42 is electrically connected between the third transistor 33 and the fourth transistor 34.

In this embodiment, as shown in fig. 3, 6, and 9, when the first transistor 31 and the fourth transistor 34 are turned on and the second transistor 32 and the third transistor 33 are turned off, the first current loop 5 is formed between the power supply module 1 and the electrode 4. Since the positive terminal of the first electrode 41 connected to the power supply module 1 has a high potential, and the negative terminal of the second electrode 42 connected to the power supply module 1 has a low potential, the first electrode 41 is a positive electrode and the second electrode 42 is a negative electrode in the process of electrolyzing water.

Under the condition that the first transistor 31 and the fourth transistor 34 are turned on, and the second transistor 32 and the third transistor 33 are turned off, the current output by the anode of the power supply module 1 passes through the first transistor 31, but does not pass through the third transistor 33, because the first electrode 41 is electrically connected between the first transistor 31 and the second transistor 32, and the second transistor 32 is turned off, the current flows to the first electrode 41 after passing through the first transistor 31, then a current path is formed between the first electrode 41 and the second electrode 42, and the current passes through the fourth transistor 34 after passing through the second electrode 42 and finally returns to the cathode of the power supply module 1, so that an electrolyzed water path is formed.

In this embodiment, as shown in fig. 4, 7 and 10, the first transistor 31 and the fourth transistor 34 are turned off, the second transistor 32 and the third transistor 33 are turned on, and the second current loop 6 is formed between the power supply module 1 and the electrode 4, because the positive terminal of the second electrode 42 connected to the power supply module 1 has a high potential, and the negative terminal of the first electrode 41 connected to the power supply module 1 has a low potential, the second electrode 42 is a positive electrode, and the first electrode 41 is a negative electrode in the process of electrolyzing water.

In the case where the first transistor 31 and the fourth transistor 34 are turned off and the second transistor 32 and the third transistor 33 are turned on, the current output from the positive electrode of the power supply module 1 passes through the second transistor 32 without passing through the first transistor 31, since the second electrode 42 is electrically connected between the third transistor 33 and the fourth transistor 34 is turned off, so that the current flows to the second electrode 42 after passing through the third transistor 33, a current path is formed between the second electrode 42 and the first electrode 41, and finally returns to the negative electrode of the power supply module 1 through the second transistor 32, forming an electrolytic water path different from that in the example of the above-described embodiment.

Referring to fig. 2 to 10, it can be seen that the positive and negative polarities of the first electrode 41 and the second electrode 42 can be changed only by controlling the on and off states of the first transistor 31, the second transistor 32, the third transistor 33, and the fourth transistor 34 by the control module 2.

In an exemplary embodiment, as shown in fig. 1, 2, 5 and 8, an electrode commutation circuit is shown, which includes a power module 1, a commutation module 3, an electrode 4 and a control module 2, the commutation module 3 being electrically connected to the power module 1, the control module 2 and the electrode 4, respectively. The commutation module 3 comprises a first control branch and a second control branch arranged in parallel, the first control branch comprises a first transistor 31 and a second transistor 32 connected in series, the second control branch comprises a third transistor 33 and a fourth transistor 34 connected in series, the first transistor 31 and the third transistor 33 are electrically connected with the positive terminal of the power supply module 1, the second transistor 32 and the fourth transistor 34 are electrically connected with the negative terminal of the power supply module 1, the electrode 4 comprises a first electrode 41 and a second electrode 42, the first electrode 41 is electrically connected between the first transistor 31 and the second transistor 32, and the second electrode 42 is electrically connected between the third transistor 33 and the fourth transistor 34.

The transistor includes a source S, a drain D, and a gate G, and is divided into an NMOS (N-Metal-Oxide-Semiconductor) transistor and a PMOS (P-Metal-Oxide-Semiconductor) transistor. For the NMOS transistor, when the voltage applied to the gate G is higher than the first predetermined value, i.e. when a high voltage is applied to the NMOS transistor, the NMOS transistor is turned on, and a current can flow from the drain D to the source S. For the PMOS transistor, when the voltage applied to the gate G is lower than the second predetermined value, i.e. the PMOS transistor applies a low potential, the PMOS transistor is turned on, and the current can flow from the source S to the drain D.

In one embodiment, as shown in fig. 2 to 4, the first transistor 31, the second transistor 32, the third transistor 33 and the fourth transistor 34 of the commutation module 3 are all NMOS transistors. The drain D of the first transistor 31 is connected to the positive electrode of the power supply module 1, the source S of the first transistor 31 is connected to the drain D of the second transistor 32, the source S of the second transistor is connected to the negative electrode of the power supply module 1 to form a first control branch, and the source S of the first transistor 31 is connected to the first electrode 41. The drain D of the third transistor 33 is connected to the positive pole of the power supply module 1, the source S of the third transistor 33 is connected to the drain D of the fourth transistor 34, the source S of the fourth transistor 34 is connected to the negative pole of the power supply module 1 to form a second control branch, and the source S of the third transistor 33 is connected to the second electrode 42. And the gates G of the first transistor 31, the second transistor 32, the third transistor 33 and the fourth transistor 34 are all electrically connected to the control module 2.

In this embodiment, as shown in fig. 3, when the control module 2 applies a high potential to the gates G of the first transistor 31 and the fourth transistor 34, the first transistor 31 and the fourth transistor 34 are turned on, and applies a low potential to the gates G of the second transistor 32 and the third transistor 33, the second transistor 32 and the third transistor 33 are turned off, so that the current output from the positive terminal of the power supply module 1 sequentially passes through the drain D and the source S of the first transistor 31, the first electrode 41, the second electrode 42, and the drain D and the source S of the fourth transistor 34, and finally returns to the negative terminal of the power supply module 1, thereby forming a current loop. Since the positive terminal of the first electrode 41 connected to the power supply module 1 has a high potential, and the negative terminal of the second electrode 42 connected to the power supply module 1 has a low potential, the first electrode 41 is a positive electrode and the second electrode 42 is a negative electrode in the process of electrolyzing water.

After the first period of time, the second electrode 42 is used as a negative electrode, and hydrogen is generated by hydrogen discharge during water electrolysis, so that OH "is opposite to impurities in water, such as magnesium ions and calcium ions, and further impurities such as magnesium hydroxide and calcium hydroxide are generated and accumulated on the first electrode 41. When it is desired to reverse the current, the polarity of the first electrode 41 and the second electrode 42 is changed to break down the deposited scale. As shown in fig. 4, the control module 2 applies a low potential to the gates G of the first transistor 31 and the fourth transistor 34, and applies a high potential to the gates G of the second transistor 32 and the third transistor 33, so that the second transistor 32 and the third transistor 33 are turned on, and the current output by the positive electrode of the power supply module 1 passes through the drain D and the source S of the third transistor 33, the second electrode 42, the first electrode 41, the drain D and the source S of the second transistor 32, and finally returns to the negative electrode of the power supply module 1, and since the positive electrode of the second electrode 42 connected to the power supply module 1 has a high potential and the negative electrode of the first electrode 41 connected to the power supply module 1 has a low potential, during the water electrolysis process, the second electrode 42 is a positive electrode and the first electrode 41 is a negative electrode, that is, electrode commutation is achieved.

In one embodiment, as shown in fig. 5 to 7, the first transistor 31, the second transistor 32, the third transistor 33 and the fourth transistor 34 of the commutation module 3 are all PMOS transistors. The source S of the first transistor 31 is connected to the positive pole of the power supply module 1, the drain D of the first transistor 31 is connected to the source S of the second transistor 32, the drain D of the first transistor 31 is connected to the first electrode 41 to form a first control branch, and the source S of the second transistor 32 is connected to the negative pole of the power supply module 1. The source S of the third transistor 33 is connected to the positive pole of the power supply module 1, the drain D of the third transistor 33 is connected to the source S of the fourth transistor 34, the drain D of the fourth transistor 34 is connected to the negative pole of the power supply module 1 to form a second control branch, and the drain D of the third transistor 33 is connected to the second electrode 42. And the gates G of the first transistor 31, the second transistor 32, the third transistor 33, and the fourth transistor 34 are all electrically connected to the control module 2.

In this embodiment, as shown in fig. 6, the control module 2 applies a low potential to the gates G of the first transistor 31 and the fourth transistor 34, so that the first transistor 31 and the fourth transistor 34 are turned on, and applies a high potential to the gates G of the second transistor 32 and the third transistor 33, so that the second transistor 32 and the third transistor 33 are turned off. The current output by the positive electrode of the power supply module 1 sequentially passes through the source S and the drain D of the first transistor 31, the first electrode 41, the second electrode 42, and the source S and the drain D of the fourth transistor 34, and finally returns to the negative electrode of the power supply module 1, because the positive end of the first electrode 41 connected to the power supply module 1 has a high potential, and the negative end of the second electrode 42 connected to the power supply module 1 has a low potential, the first electrode 41 is the positive electrode and the second electrode 42 is the negative electrode in the process of electrolyzing water.

When the current needs to be commutated, as shown in fig. 7, the control module 2 applies a high potential to the gates G of the first transistor 31 and the fourth transistor 34, and applies a low potential to the gates G of the second transistor 32 and the third transistor 33, so that the second transistor 32 and the third transistor 33 are turned on, and the current output by the positive electrode of the power supply module 1 sequentially passes through the source S and the drain D of the third transistor 33, the second electrode 42, the first electrode 41, and the source S and the drain D of the second transistor 32, and finally returns to the negative electrode of the power supply module 1, because the positive end of the second electrode 42 connected to the power supply module 1 has a high potential, and the negative end of the first electrode 41 connected to the power supply module 1 has a low potential, in the process of electrolyzing water, the second electrode 42 is a positive electrode, and the first electrode 41 is a negative electrode, that is, the electrode commutation is achieved.

In one embodiment, as shown in fig. 8, the first transistor 31 and the third transistor 33 are PMOS transistors, and the second transistor 32 and the fourth transistor 34 are NMOS transistors. In one example, referring to fig. 9, to further facilitate control of the first transistor 31, the second transistor 32, the third transistor 33, and the fourth transistor 34, the gates G of the first transistor 31 and the second transistor 32 may be coupled together and further coupled to the control module 2, and the gates G of the third transistor 33 and the fourth transistor 34 may be coupled together and further coupled to the control module 2. Based on the above connection manner, the control module 2 may apply a low voltage to the gates G of the first transistor 31 and the second transistor 32 through one pin thereof, and since the first transistor 31 is a PMOS transistor and the second transistor 32 is an NMOS transistor, the first transistor 31 is turned on and the second transistor 32 is turned off. Similarly, the control module 2 may apply a high voltage to the third transistor 33 and the fourth transistor 34 at the same time through its own pin, and since the third transistor 33 is a PMOS transistor and the fourth transistor 34 is an NMOS transistor, the third transistor 33 is turned off and the fourth transistor 34 is turned on. In this example, the anode of the power supply module 1, the first transistor 31, the first electrode 41, the second electrode 42, the fourth transistor 34 and the cathode of the power supply module 1 form a conductive path.

In another example, referring to fig. 10, the control module 2 may apply a high voltage to the gates G of the first transistor 31 and the second transistor 32 through one pin thereof, and since the first transistor 31 is a PMOS transistor and the second transistor 32 is an NMOS transistor, the first transistor 31 is turned off and the second transistor 32 is turned on. Similarly, the control module 2 may apply a low voltage to the third transistor 33 and the fourth transistor 34 through its own pin, and since the third transistor 33 is a PMOS transistor and the fourth transistor 34 is an NMOS transistor, the third transistor 33 is turned on and the fourth transistor 34 is turned off. In this example, the anode of the power supply module 1, the third transistor 33, the second electrode 42, the first electrode 41, the second transistor 32 and the cathode of the power supply module 1 form a conductive path.

It should be noted that the PMOS transistor can be turned on only when the electric potential of the gate G is lower than the second preset voltage, as shown in fig. 8 to 10, since the voltage of the power supply positive electrode applied to the first transistor 31 and the third transistor 33 by the power supply module 1 remains unchanged, the on/off state switching can be stably realized only by ensuring that the voltage applied to the gate G by the control module 2 is lower than the power supply voltage. Taking the first transistor 31 as an example, referring to fig. 3, if the first transistor 31 is an NMOS transistor, the voltage of the source S of the first transistor 31 is uncertain, because the voltage of the source S to ground has two states, i.e., a low voltage when the first transistor 31 is turned off and a high voltage when the first transistor 31 is turned on, so that the voltage of the gate G for controlling the turn-on of the first transistor 31 cannot be determined. In this embodiment, PMOS transistors are used as the first transistor 31 and the third transistor 33, and an isolation power supply is not required, so that the circuit is simplified.

The NMOS transistor needs to be turned on when the gate G is higher than the source S, as shown in fig. 8 to 10, since the sources S of the second transistor 32 and the fourth transistor 34 are directly grounded, so that the source S is a fixed value, the switching between the on/off states can be stably realized only by applying a potential higher than the fixed value to the gate G by the control module 2. Taking the second transistor 32 as an example, if the second transistor 32 is a PMOS transistor, because the voltage entering the source S of the second transistor 32 is the voltage after passing through the electrode 4, the voltage at the source S of the second transistor 32 is uncertain because the electrode 42 has a certain resistance, and a low potential needs to be applied to the PMOS transistor when the PMOS transistor needs to be turned on, but because the voltage at the source S is uncertain, the voltage of the gate G for controlling the turn-on of the second transistor 32 is not easy to control. In this embodiment, NMOS transistors are used as the second transistor 32 and the fourth transistor 34, so that the circuit is simplified.

As shown in fig. 1, the control module 2 in this embodiment includes a Micro Controller Unit (MCU). Illustratively, a timing circuit may be provided inside the micro control unit to intermittently control the on and off of the first transistor 31, the second transistor 32, the third transistor 33 and the fourth transistor 34 to achieve a periodic commutation of the current such that the first electrode 41 and the second electrode 42 of the electrode 4 exchange polarities.

The electrode commutation circuit further comprises a transistor driver (not shown) which is in communication connection with the control module 2 and can apply different potentials to the gate G of the transistor according to instructions sent by the control module 2. In one example, a transistor driver may be integrated in the control module 2, the transistor driver being electrically connected to the first transistor 31, the second transistor 32, the third transistor 33 and the fourth transistor 34, respectively, so that the micro control unit can control the switching on and off of the respective transistors through the transistor driver, thereby implementing the commutation of the electrode 4. In another example, a transistor driver may be integrated in the commutation module 3, and the transistor driver is electrically connected to the first transistor 31, the second transistor 32, the third transistor 33, and the fourth transistor 34, respectively, so that the control module 2 is directly connected to the transistor driver to control the transistors, thereby realizing the commutation of the electrode 4. In a further example, a transistor driver is provided separately from the micro control unit and the commutation module 3, the transistor driver being connected to the first transistor 31, the second transistor 32, the third transistor 33 and the fourth transistor 34, respectively, so that the micro control unit can commutate the electrode 4 by controlling the respective transistors via the transistor driver. Wherein the transistor driver includes a full bridge transistor driver and a half bridge transistor driver.

In this embodiment, the power supply module 1 is electrically connected to the control module 2. This does not constitute a limitation to the technical solution of the present disclosure, and it can be understood that the control module 2 may also be connected to other external power sources, and the control module 2 may also supply power by itself through an internal power source.
