[0046] In order to make the technical personnel in the technical field better understand the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described in combination with the drawings in the embodiment of the present invention. Unless otherwise defined, all technical and scientific terms used in this article have the same meaning as those commonly understood by the technical personnel in the technical field of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0047] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0048] See also Figures 1 to 3, a floor scrubber base station intelligent control circuit, characterized in that it includes: a controller, a fan driving circuit and a temperature heating circuit, wherein the fan driving circuit is connected to the controller to drive the fan to generate flowing air under the control of the controller; the temperature heating circuit is connected to the controller, and is used to heat the flowing air generated by the fan to generate hot air, and use the hot air to blow dry the parts to be dried of the cleaning equipment. Specifically, during the floor scrubber, the water in the floor scrubber bucket is pumped out to the roller brush, thereby wetting the roller brush, and the roller brush is driven to move by the floor scrubber to clean the floor. After the floor scrubber sprays water to clean the roller brush, the roller brush is wet, so it is necessary to blow hot air to the roller brush through the base station to facilitate the timely drying of the roller brush. In an embodiment of the utility model, the hot air can be generated by the joint action of the fan and the heating device. Among them, the fan generates flowing air under the control of the controller and the fan driving circuit. The heating device heats the flowing air under the control of the controller and the temperature heating circuit to generate hot air, and the hot air is output to the position of the roller brush of the floor scrubber, so that the roller brush can be quickly dried. In this way, after the floor scrubber has finished scrubbing the floor, it can be blown dry in time, so that the floor scrubber can remain dry when not in use.

[0049] See also Figure 1 and Figure 4 , the intelligent control circuit of the floor scrubber base station also includes: a temperature detection circuit, the temperature detection circuit is connected to the controller, the controller obtains the hot air temperature through the temperature detection circuit, and controls the temperature heating circuit to heat according to the hot air temperature. The temperature of the generated hot air can be detected by the temperature detection circuit, so that the actual temperature of the hot air can be obtained. Since the hot air is blown out of the roller brush, on the one hand, the temperature cannot be too high to damage the roller brush, and on the other hand, it cannot hurt the human body. Therefore, it is necessary to adjust the temperature of the hot air within the set temperature range. The temperature detection circuit can obtain the temperature value of the hot air, and the heating device can be heated and controlled according to the temperature value of the hot air. For example, when it is detected that the hot air temperature is close to the maximum set temperature. The heating device can be controlled by the temperature heating circuit to stop heating for a period of time, and then turn on the heating again, so that the temperature can be adjusted. Ensure that the hot air temperature is within the set range.

[0050] See also Figure 1 and Figure 5, the intelligent control circuit of the floor scrubber base station also includes: a serial communication circuit, the serial communication circuit is connected to the controller, and the controller communicates with the cleaning equipment through the serial communication circuit to obtain the in-place status of the cleaning equipment, and controls the drying of the parts to be dried of the cleaning equipment according to the in-place status. Since the base station needs to detect that the floor scrubber is in place, it outputs hot air to dry the roller brush of the floor scrubber, and does not need to be dried when it is not in place. When the floor scrubber is in place, a signal can be output to the controller through the serial communication circuit to notify the controller to perform a drying operation.

[0051] See also Figure 1 and Figure 7 , the intelligent control circuit of the floor scrubber base station also includes: a battery charging circuit, which is used to convert the input AC power into a power supply for the cleaning equipment and charge the in-situ cleaning equipment. Specifically, when the floor scrubber equipment is placed in the designated position, the power interface of the floor scrubber equipment is connected to the charging interface of the base station. In this way, when the controller detects that the dust removal equipment is in the in-situ state, the power supply can be output through the charging circuit to power and / or charge the dust removal equipment. In this way, the floor scrubber equipment can be in a fully charged state when it is used next time, thereby ensuring the power endurance of the floor scrubber equipment.

[0052] See also Figure 2 and Figure 6 The fan driving circuit includes: a first MOS tube Q4 and a second diode D9, the gate of the first MOS tube Q4 is connected to one end of a first resistor R43, the other end of the first resistor R43 is connected to one end of a second resistor RJ3, the other end of the second resistor RJ3 is connected to the fan control end of the controller, the drain of the first MOS tube Q4 is connected to one end of the fan, the other end of the fan is connected to a power supply through a third resistor R42, the source of the first MOS tube Q4 is connected to a reference ground through a fourth resistor R46, and the source of the first MOS tube Q4 is also connected to the current detection end of the controller through a fifth resistor R47; the anode of the second diode D9 is connected to the drain of the first MOS tube Q4, and the cathode of the second diode D9 is connected to the other end of the fan.

[0053] Specifically, the working process of the fan driving circuit is that when the controller detects that the floor scrubber is in the in-position state, a high-level signal can be output through the CNT_FAN signal terminal, and the high-level signal can turn on the first MOS tube Q4, thereby connecting the power supply circuit of the fan, so that the fan can rotate, thereby generating flow control. On the contrary, when the fan rotates for a set time, the controller can output a low-level signal to turn off the first MOS tube Q4, and at the same time, the fan can stop rotating. At this time, the inductor coil in the fan may generate a flyback signal, which can be recovered through the second diode D9 to avoid damage to the first MOS tube Q4.

[0054] See also Figure 2 and Figure 6 The fan driving circuit also includes: a third diode D10-1, a fourth diode D10-2 and a capacitor C20, the anode of the third diode D10-1 is connected to the current detection end of the controller, and the cathode of the third diode D10-1 is connected to a DC power supply; the cathode of the fourth diode D10-2 is connected to the current detection end of the controller, and the anode of the fourth diode D10-2 is connected to a reference ground; one end of the capacitor C20 is connected to the current detection end of the controller, and the other end of the capacitor C20 is connected to the reference ground.

[0055] Specifically, the third diode D10-1 and the fourth diode D10-2 can form a clamping circuit to clamp the potential of the current detection end of the controller within a voltage range of 0 to 5V, thereby preventing the abnormal signal of the current detection end from damaging the controller. The capacitor C20 is a filter capacitor that can filter out pulse signals. The working process of the circuit is that when the voltage of the current detection end of the controller is higher than 5V, the third diode D10-1 can be turned on to pull the potential of the current detection end of the controller down to 5V, and when the voltage of the current detection end of the controller is lower than 0V, the fourth diode D10-2 can be turned on to pull the potential of the current detection end of the controller up to 0V, thereby clamping the potential of the current detection end of the controller within a voltage range of 0 to 5V, thereby preventing the abnormal signal of the current detection end from damaging the controller.

[0056] See also Figure 3 and Figure 6The temperature heating circuit includes: a transistor Q5, an optical coupler U6 and a bidirectional thyristor TR1, the base of the transistor Q5 is connected to the heating control end of the controller through a sixth resistor R48, and the emitter of the transistor Q5 is connected to the reference ground; the cathode of the light-emitting diode end of the optical coupler U6 is connected to the collector of the transistor Q5 through a seventh resistor RJ4, the anode of the light-emitting diode end of the optical coupler U6 is connected to a DC power supply through an eighth resistor R50, one end of the photosensitive diode end of the optical coupler U6 is connected to one end of a ninth resistor R53, the other end of the ninth resistor R53 is connected to one end of a tenth resistor R54, and the other end of the tenth resistor R54 is connected to an alternating current power supply end; the controlled end of the bidirectional thyristor TR1 is connected to the other end of the photosensitive diode end of the optical coupler U6, a power supply end of the bidirectional thyristor TR1 is connected to the one power supply end of the alternating current, the other power supply end of the bidirectional thyristor TR1 is connected to one end of the heating device, and the other end of the heating device is connected to the other power supply end of the alternating current.

[0057] Specifically, the working process of the temperature heating circuit is that when the heating device needs to be controlled to heat the flowing air, the controller can output a high-level signal through the CNT_PTC signal terminal, and the high-level signal can turn on the transistor Q5, and then turn on the optical coupler U6, and give a trigger signal to the controlled end of the bidirectional thyristor TR1, so that the two power supply ends of the bidirectional thyristor TR1 can be turned on, and then the power supply circuit of the heating device can be turned on, and the heating device starts heating. On the contrary, when the controller outputs a low-level signal, the heating device stops heating.

[0058] See also Figure 4 and Figure 6 The temperature detection circuit includes: a temperature sensor, one end of the temperature sensor is connected to the temperature detection end of the controller through an eleventh resistor R57, the other end of the temperature sensor is connected to a reference ground, the one end of the temperature sensor is also connected to one end of a twelfth resistor R56, and the other end of the twelfth resistor R56 is connected to a DC power supply.

[0059] Specifically, in one embodiment of the utility model, the temperature sensor may be a thermistor. Since the resistance value of the thermistor changes linearly according to the change of temperature, the corresponding temperature value can be obtained by measuring the resistance value. Since the temperature sensor and the twelfth resistor R56 form a voltage-dividing resistor. In this way, the 5V voltage can be divided and output to the temperature detection end of the controller through the ADC_T_NTC signal end, so as to obtain the heating temperature of the hot air. Among them, capacitor C23 and capacitor C24 can filter out interference signals to ensure the reliability of the collected temperature.

[0061] Specifically, the serial communication circuit communicates with the floor scrubber through a single port. When the floor scrubber is in place, a high or low level signal can be output to the gate of the second MOS tube Q2 through the COMM signal terminal, so that the second MOS tube Q2 can be turned on or off, thereby outputting a signal to the signal receiving end of the controller through the UART_RX signal terminal. The controller can receive the signal output by the floor scrubber, thereby obtaining that the floor scrubber is in place, and controlling the output of hot air to dry the roller brush of the floor scrubber. On the contrary, when the controller needs to output a signal to the floor scrubber, a high ground level signal can be output through the UART_TX signal terminal, and the third MOS tube Q3 can be turned on or off. Thus, the COMM signal terminal with high and low level values ​​is output, and the floor scrubber can receive the signal from the base station.
