[0046] In one embodiment, when the cleaning control module of the cleaning device generates a 220V AC water inlet signal, rectifier bridge D1 converts the water inlet signal into DC power, causing the light-emitting device in optocoupler IS1 to illuminate. This further connects the first and second output terminals of optocoupler IS1, generating a low-voltage second control signal and illuminating LED diode DS3. When the cleaning control module does not generate a water inlet signal, the second control signal is raised to 5V, and LED diode DS3 does not illuminate.

[0047] The water inlet detection module 20 can convert the 220V AC water inlet signal into a second control signal with an amplitude of 5V, and plays the role of signal isolation and light indication.

The control module 40 can set parameters such as the feeding time and feeding amount in different cleaning modes based on these input signals. In other embodiments, the number of input modules 30 can also be other.

[0050] like Figure 6 and Figure 7 As shown, the control module 40 includes a control unit and a signal unit. The control unit is connected to the second end of the first transistor Q1 to receive a first control signal, the control unit is connected to the second end of the fifth resistor R5 to receive a second control signal, and the control unit is connected to the second end of the switch S1 to receive an input signal. The control unit generates a third control signal based on the first control signal and the second control signal. The signal unit is connected to the control unit and the feeding pump of the cleaning device to generate a feeding control signal based on the third control signal.

[0051] like Figure 6 As shown, the control unit includes a control chip U2 and its peripheral circuits. The model of the control chip U2 is preferably CH32V103C.

[0052] Pins 39 through 42 of the control chip U2 are connected to the second end of the first transistor Q1 in a mode detection module 10 to receive a first control signal. Pin 11 of the control chip U2 is connected to the second end of the fifth resistor R5 in the water ingress detection module 20 to receive a second control signal. Pins 13 through 16 of the control chip U2 are connected to the second end of the switch S1 in an input module to receive an input signal.

[0053] like Figure 7 As shown, the signal unit includes a switch subunit, a relay, a light emitting diode DS5, a diode D3, a resistor R49 and a capacitor C21.

[0054] Among them, the relay includes a coil and a contact switch K1, the switch subunit is connected to pin 2 of the control chip U2 to receive a third control signal, the switch subunit is connected to the first end of the coil and the ground voltage to control the on and off between the first end of the coil and the ground voltage based on the third control signal, the second end of the coil and the first end of the contact switch K1 are connected to the power supply voltage, and the second end of the contact switch K1 is connected to the feeding pump of the cleaning equipment to generate a feeding control signal.

[0055] The first end of resistor R49 and the cathode of diode D3 are connected to the power supply voltage. The second end of resistor R49 is connected to the anode of light-emitting diode DS5. The cathode of light-emitting diode DS5, the anode of diode D3, and the first end of capacitor C21 are connected to the first end of the coil. The second end of capacitor C21 is connected to ground. Resistor R49 is used for current limiting, diode D3 is used for circuit protection, and capacitor C21 is used for filtering.

[0056] The switch subunit includes a second transistor Q2, a third transistor Q3, a seventh resistor R7, an eighth resistor R8, a ninth resistor R9, and a tenth resistor R10. A first end of the seventh resistor R7 and a first end of the second transistor Q2 are connected to a power supply voltage, a second end of the seventh resistor R7 and a first end of the eighth resistor R8 are connected to pin 2 of the control chip U2 to receive a third control signal, a second end of the eighth resistor R8 is connected to the control end of the second transistor Q2, a second end of the second transistor Q2 and a first end of the ninth resistor R9 are connected to the first end of the tenth resistor R10, a second end of the tenth resistor R10 is connected to the control end of the third transistor Q3, a second end of the ninth resistor R9 and a first end of the third transistor Q3 are connected to a ground voltage, and a second end of the third transistor Q3 is connected to the first end of the coil.

[0057] When the third control signal is high, the second transistor Q2 is turned off, and the third transistor Q3 is also turned off. The coil is not powered, the LED DS5 does not emit light, and the contact switch K1 is open, generating a low-level feeding control signal, controlling the feeding pump not to add detergent. Conversely, when the third control signal is low, a high-level feeding control signal is generated, controlling the feeding pump to add detergent, and the LED DS5 emits light.

[0058] like Figure 8 As shown, display module 70 includes digital display tubes DS1 and DS2 and their peripheral circuits. Control chip U2 also generates display signals via its own pins 19 to 22. Digital display tubes DS1 and DS2 are connected to pins 19 to 22 of control chip U2, and display is performed based on the display signals.

[0059] like Figure 9 As shown, the communication module 60 includes a transceiver chip U5, preferably a MAX485EESA. Pins 2 and 3 of the transceiver chip U5 are connected to pin 46 of the control chip U2. Pin 1 of the transceiver chip U5 is connected to pin 31 of the control chip U2. Pin 4 of the transceiver chip U5 is connected to pin 30 of the control chip U2. Pins 6 and 7 of the transceiver chip U5 are connected to external devices.

[0060] In one embodiment, the first transistor Q1 and the second transistor Q2 are PNP transistors, and the third transistor Q3 is an NPN transistor.

In other embodiments, the first transistor Q1 and the second transistor Q2 may be NPN transistors or other devices, and the third transistor Q3 may be a PNP transistor or other device. The connection and control methods of each transistor can be adjusted adaptively.

[0061] During the actual working process, the control module 40 can first be configured with parameters through the input module 30 to set parameters such as the time for adding detergent, the amount of addition, the interval between two additions, etc. under different cleaning modes. At the same time, the control module 40 controls the display module 70 for digital display so that the staff can see the specific set parameters.

[0062] Next, the mode detection module 10 receives the cleaning device's mode signal and generates a first control signal. The control module 40 determines the selected cleaning mode based on the first control signal. The water inflow detection module 20 generates a second control signal upon detecting water inflow. Upon receiving the second control signal, the control module 40 simultaneously generates a dosing control signal to control the dosing pump to add detergent. The dosing time and amount can be controlled based on the cleaning mode.

[0063] During the subsequent washing process, the cleaning equipment will be filled with water multiple times. Since the interval time for adding detergent is set, the control module 40 controls the feeding pump to add detergent once and will no longer continue to add detergent according to the second control signal until the interval time ends. The interval time can be set to the time required for cleaning in this cleaning mode.

[0064] In summary, the feeding control system in this scheme can control the feeding pump to add detergent according to the current cleaning mode of the cleaning equipment and based on the water inlet of the cleaning equipment. It can also set parameters such as feeding time, feeding amount, feeding interval time under different cleaning modes through the input module to adapt to the feeding requirements of different cleaning modes.

[0065] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

[0066] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
