[0035] 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.

[0036] 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.

[0037] See also Figure 1 and Figure 2 The embodiment of the utility model provides an intelligent control circuit of a dust collection base station, including: an in-place detection circuit, a controller and a fan drive circuit, wherein the in-place detection circuit is used to detect the in-place status of a cleaning device; the controller and the in-place detection circuit are used to obtain in-place status information of the cleaning device through the in-place detection circuit; the fan drive circuit and the controller, and when the controller obtains that the cleaning device is in place through the in-place status information, the fan drive circuit is controlled to drive the fan to rotate, so as to suck the dust and garbage of the cleaning device into the dust collection bucket.

[0038] Specifically, after the dust removal device (such as a vacuum cleaner) has finished dust removal, the dust or garbage in the dust removal device needs to be moved out to the dust collection bucket to prevent the dust or garbage in the dust removal device from filling up the interior of the dust removal device. By emptying the dust or garbage inside the dust removal device, it is convenient for the dust removal device to perform dust removal operations next time. In the prior art, the dust or garbage in the dust removal device is mainly poured out manually to empty the dust or garbage in the dust removal device. In the embodiment of the utility model, the dust or garbage in the dust removal device is cleaned by means of a dust collection base station. The process is that when the dust removal device is used up and the dust or garbage in the device needs to be cleared, the dust removal device can be placed close to the dust collection base station or at a specific position of the dust collection base station, and the dust or garbage interface of the dust removal device is connected to the interface of the dust collection base station. In this way, the in-place state of the dust collection device can be detected by the in-place detection circuit, and the in-place state information can be sent to the controller. When the controller obtains that the dust collection device is in place, it can drive the fan to rotate by controlling the fan drive circuit. After the fan rotates under the control of the controller, it can generate a certain suction force. The suction force generated by the fan can absorb the dust or garbage in the dust collection device into the dust collection bucket of the dust collection base station. In this way, the dust or garbage in the dust collection device can be automatically removed.

[0039] See also Figure 1 and Figure 2 , the intelligent control circuit of the dust collection base station also includes a zero-crossing detection circuit, which is connected to the controller. The controller is also used to obtain the AC power supply zero-crossing signal of the fan through the zero-crossing detection circuit, and control the fan according to the zero-crossing signal. Since the power of the fan is relatively large, and the fan is powered by AC power. The AC electric zero-crossing information can be obtained through the zero-point detection circuit, and the fan is switched on and off when the AC power is at zero point to minimize the generation of arcs. In addition, the controller can perform energy-saving control on the fan when there is a zero-point signal. Because of low power consumption considerations, the zero-crossing signal has only half-wave pulses, and the controller automatically identifies 50 / 60Hz and correctly sets the thyristor opening delay.

[0040] See also Figure 1 and Figure 2, the intelligent control circuit of the dust collection base station also includes a charging circuit, and the controller is also connected to the charging circuit, and when the controller obtains that the cleaning device is in place through the in-place status information, the cleaning device is charged by controlling the charging circuit. Specifically, when the dust removal device is placed in the specified position, the power interface of the dust removal device is connected to the charging interface of the dust removal base station. In this way, when the controller detects that the dust removal device is in place, it can output the power supply by controlling the charging circuit, thereby powering and / or charging the dust removal device. In this way, the dust removal device can be in a fully charged state when it is used next time, ensuring the power supply life of the dust removal device. When it is detected that the dust removal device is not in place, the circuit used for outputting power and / or charging can be turned off to avoid abnormal situations.

[0041] See also Figure 1 and Figure 2 , the intelligent control circuit of the dust collection base station also includes a dust collection detection circuit, and the dust collection detection circuit is connected to the controller. The controller is also used to obtain the state of the dust collection bucket through the dust collection detection circuit, and control the fan to stop dust suction when the dust collection bucket is full and the cleaning device is in place. Since the dust collection bucket in the dust collection base station is full of dust after multiple dust collections. When this happens, on the one hand, it is necessary to remind the user to empty the dust in the dust collection bucket of the dust collection base station. On the other hand, when the dust collection bucket is in a full dust bucket state, even if the dust removal device is in the in state, the fan is not controlled to suction dust. This is because after the dust collection bucket is full, it can no longer hold dust, so the fan is controlled to stop suctioning.

[0042] See also Figures 1 to 3 The intelligent control circuit of the dust collection base station further includes: an indication interface circuit and an indication and switch circuit, the indication and switch circuit is connected to the controller through the indication interface circuit, and the indication and switch circuit includes an indicator light, which is used to indicate the charging status and / or the in-place status of the cleaning device under the action of the controller. Figure 3 As shown in , the indication interface circuit may include a diode LED1, a diode LED2 and a control switch SW1, and the charging status of the dust collecting device may be indicated by the diode LED1. For example, the green LED flashes at a frequency of 0.5HZ during charging, and the light goes out after the charging is completed. The in-place status of the dust collecting device may be indicated by the diode LED2. For example, the LED light goes out after the vacuum cleaner is removed from the dust collecting bucket.

[0043] See also Figure 2The fan driving circuit includes: a first MOS tube Q5, a first optocoupler U3 and a bidirectional thyristor TR1, the base of the first MOS tube Q5 is connected to the fan control end of the controller through a first resistor R52, and the source of the first MOS tube Q5 is connected to the reference ground; the cathode of the light emitting diode end of the first optocoupler U3 is connected to the drain of the first MOS tube Q5 through a second resistor R53, and the anode of the light emitting diode end of the first optocoupler U3 is connected to the power supply; the controlled end of the bidirectional thyristor TR1 is connected to one end of the photosensitive diode of the first optocoupler U3; the other end of the photosensitive diode of the first optocoupler U3 is connected to a power supply end of the bidirectional thyristor TR1, one end of the fan and one end of the AC power supply through a third resistor R54 and a fourth resistor R56, respectively, and the other power supply end of the bidirectional thyristor TR1 is connected to the other power supply end of the fan.

[0044] Specifically, the working process of the fan drive circuit is that when the controller needs to absorb the dust or garbage in the vacuum cleaner into the dust collection bucket, the fan needs to be controlled to rotate. The controller can control the first MOS tube Q5 to conduct by outputting a high-level signal, so that the light-emitting diode end of the optocoupler emits light, thereby controlling the photosensitive diode end of the first optocoupler U3 to conduct, and then giving a trigger signal to the bidirectional thyristor TR1, so that the two power supply ends of the bidirectional thyristor TR1 are also conducted, and the alternating current can be output to the fan, thereby powering the fan. The fan starts to rotate and absorbs the dust or garbage in the vacuum cleaner into the dust collection bucket. On the contrary, when the controller outputs a low voltage level, the bidirectional thyristor TR1 is cut off, and the fan stops dust collection.

[0045] See also Figure 2The zero-crossing detection circuit includes: a second optical coupler U7 and a second MOS tube Q6, the anode of the light-emitting diode end of the second optical coupler U7 is connected to one end of a fifth resistor R64, the other end of the fifth resistor R64 is connected to one end of a sixth resistor R61, the other end of the sixth resistor R61 is connected to the cathode of a first diode D3, the anode of the first diode D3 is connected to one end of an AC power supply, the cathode of the light-emitting diode end of the second optical coupler U7 is connected to the other end of the AC power supply, and the collector of the photosensitive transistor end of the second optical coupler U7 is connected to a DC power supply through a seventh resistor R63. , the emitter of the phototransistor end of the second optical coupler U7 is connected to the reference ground through the eighth resistor R66; the gate of the second MOS tube Q6 is connected to the emitter of the phototransistor end of the second optical coupler U7, the source of the second MOS tube Q6 is connected to the reference ground, the drain of the second MOS tube Q6 is connected to one end of the ninth resistor R65, the other end of the ninth resistor R65 is connected to one end of the tenth resistor R62, the other end of the tenth resistor R62 is connected to a DC power supply, and the drain of the second MOS tube Q6 is also connected to the zero-crossing detection end of the controller through the ninth resistor R65.

[0046] Specifically, the working process of the zero-crossing detection circuit is that when the AC signal output by the detected AC power arrives at the zero point of the upper half waveform, the second optical coupler U7 can be illuminated through the diode D7, the sixth resistor R61 and the fifth resistor R64, and the photosensitive transistor end of the second optical coupler U7 is turned on, and then a high-level signal can be output to the gate of the second MOS tube Q6, so that the second MOS tube Q6 can be turned on, and then a low-level signal can be output to the controller, and the signal at the zero-point signal end of the controller is converted from a high level to a low level, and the low-level state is maintained during the time of the upper half waveform. When the upper half waveform ends and passes through the zero point, it enters the lower half waveform. Due to the unidirectional conductivity of the first diode D3, the current of the second optical coupler U7 is zero, the optical coupler is turned off, and the second MOS tube Q6 is also turned off. At this time, the signal at the zero-point signal end of the controller is converted from a low level to a high level. In this way, the controller can obtain whether the AC power passes through zero electricity through the high and low level jumps of the level, and control the rotation of the fan according to the AC power zero point information.

[0047] See also Figure 2 , the charging circuit includes: a third MOS tube Q4 and a fourth MOS tube Q2, the gate of the third MOS tube Q4 is connected to the charging control terminal of the controller through an eleventh resistor R12, and the source of the third MOS tube Q4 is connected to the reference ground;

[0048] The gate of the fourth MOS tube Q2 is connected to the drain of the third MOS tube Q4, the source of the fourth MOS tube Q2 is connected to the charging power supply, the source of the fourth MOS tube Q2 is also connected to the gate of the fourth MOS tube Q2 through the twelfth resistor R4, and the drain of the fourth MOS tube Q2 outputs the charging power supply to the charging interface, and the cleaning device is charged through the charging interface. Figure 2 As shown in , the source of the fourth MOS tube Q2 can be connected to a DC charging power supply, and the voltage is stabilized by a parallel voltage regulator diode, and the pulse signal is filtered to output a stable DC power with less interference. When the controller detects that the vacuum cleaner is in place, it is necessary to control the output charging power supply to charge the vacuum cleaner. At this time, the control can output a high-level signal, so that the third MOS tube Q4 can be turned on, and then the fourth MOS tube Q2 can also be turned on, so that the DC charging power supply is output to the vacuum cleaner through the charging interface CN2 to charge the vacuum cleaner. On the contrary, when it is detected that the vacuum cleaner is fully charged and the charging circuit needs to be turned off, the controller can output a low-level signal to turn off the third MOS tube Q4 and the fourth MOS tube Q2 respectively, and the DC charging power supply is not output to the outside.

[0049] See also Figure 2 , the charging circuit also includes: a second diode D1, a thirteenth resistor R7 and a fifteenth resistor R13, the drain of the fourth MOS tube Q2 outputs the charging power supply to the charging interface through the second diode D1; wherein the anode of the second diode D1 is connected to the drain of the fourth MOS tube Q2, and the cathode of the fourth MOS tube Q2 is connected to the charging interface; one end of the thirteenth resistor R7 is connected to the cathode of the second diode D1, and the other end of the thirteenth resistor R7 is connected to the voltage detection end of the controller through the fourteenth resistor R31; one end of the fifteenth resistor R13 is connected to the other end of the thirteenth resistor R7, and the other end of the fifteenth resistor R13 is connected to the reference ground. The unidirectional conductivity of the second diode D1 can avoid the backflow of the power supply of the dust removal equipment. The thirteenth resistor R7 and the fifteenth resistor R13 form a voltage divider circuit, and the voltage of the dust removal equipment can be collected and divided, and then output to the voltage detection end of the controller, so that the charging voltage of the dust removal equipment can be detected, and then it can be determined whether the dust removal equipment is fully charged. When it is fully charged, the charging circuit can be disconnected to ensure the safety of the charging circuit.

[0050] See also Figure 2, the in-place detection circuit includes: a Hall sensor, the power supply end of the Hall sensor is connected to a DC power supply, the ground end of the Hall sensor is connected to a reference ground, the signal output end of the Hall sensor is connected to the in-place detection end of the controller through a sixteenth resistor R19, and the in-place detection end of the controller is also connected to the DC power supply through a seventeenth resistor R11. Since the Hall sensor has the characteristic of non-contact. When the dust removal equipment approaches, the Hall sensor can detect the dust removal equipment, thereby outputting an in-place signal, and the in-place signal can be output to the in-place signal detection end of the controller through the sixteenth resistor R19. In this way, the controller can obtain whether the dust removal equipment is in place.

[0051] See also Figure 2 , the dust collection detection circuit includes: a pressure sensor, one end of the pressure sensor is connected to one end of the eighteenth resistor R3, the other end of the eighteenth resistor R3 is connected to the pressure detection end of the controller, the pressure detection end of the controller is also connected to the DC power supply through the nineteenth resistor R1, and the other end of the pressure sensor is connected to the reference ground. There is a pressure sensor inside the dust bucket. Since dust and / or garbage have a certain weight, when the dust bucket detects that the weight exceeds the set voltage value through the pressure sensor, the pressure sensor is closed when the dust is full, and the pressure detection end of the controller changes from a high level to a low level, judging that the dust bag is full of dust. When the dust is full, the motor stops rotating, and the red LED flashes at a frequency of 0.5HZ, which can prompt the user to empty the garbage in the dust bucket.
