Description

[0002] At present, the common cleaning device with a synchronization function on the market has limited pins of a gear switch. In order to meet the needs of gear recognition, most of the pins of the gear switch are occupied, so that the gear switch is only connected with a live wire, and a zero line is directly connected to a motor. This means that the gear switch can only control the on-off of the live wire. Even in the case of closing the gear switch, the zero line still remains in the power-on state, and the global power-off (i.e., the live wire and the zero line are simultaneously powered off) cannot be realized. As a result, the motor may generate induced current or other electrical problems in the case of the zero line being powered on, which not only increases the risk of equipment failure, but also may pose a threat to the safety of users.

Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0056] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the present invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0057] One embodiment of this application provides a control module for a cleaning device, such as... Figure 1 As shown, the control module may include:

[0058] The gear switch 110 is used to control the on / off of the power supply circuit between the synchronous socket 120 and the motor 130 in the cleaning device.

[0059] The gear switch 110 includes:

[0060] The first input terminal n1 is used to connect to the first terminal a1 of the external power supply 140.

[0061] The second input terminal n2 is used to connect to the second terminal a2 of the external power supply 140.

[0062] The first output terminal n3 is used to connect to the first terminal c1 of the motor 130.

[0063] The second output terminal n4 is used to connect to the second terminal c2 of motor 130.

[0064] The third output end n5 is used for connecting with the first end b1 of the synchronous socket 120 and the first end c1 of the motor 130.

[0065] The fourth output end n6 is used for connecting with the second end b2 of the synchronous socket 120 and the second end c2 of the motor 130.

[0066] When the gear switch 110 is set at the first gear, the first input end n1 is connected with the first output end n3 and the second input end n2 is connected with the second output end n4; when the gear switch 110 is set at the second gear, the first input end n1 is connected with the third output end n5 and the second input end n2 is connected with the fourth output end n6; when the gear switch 110 is set at the third gear, the first input end n1 is not connected with the first output end n3 and the third output end n5, and the second input end n2 is not connected with the second output end n4 and the fourth output end n6.

[0067] In some embodiments, the external power source 140 can be an alternating current power source. The motor 130 in the cleaning device can be an alternating current motor. The cleaning device can be a cleaning device with a synchronous function. The first gear of the gear switch 110 can be an independent gear, under which the motor 130 of the cleaning device works independently. The second gear can be a synchronous gear, under which the motor 130 of the cleaning device works synchronously with the power tool connected in the synchronous socket. The third gear can be an OFF gear, under which the motor 130 does not work. Optionally, the power tool can include a power drill, a power saw, etc.

[0068] In some embodiments, please refer to Figure 1The gear switch 110 can be a double-pole double-throw switch structure, for example, a rocker switch can be used. The gear switch 110 has six input / output ports, including two input ports (n1, n2) and four output ports (n3-n6). The first input port n1 and the second input port n2 of the gear switch 110 are two common ports in the double-pole double-throw switch. Among them, the first output port n3 and the third output port n5 of the gear switch 110 are two movable ports corresponding to the first input port n1, and the second output port n4 and the fourth output port n6 of the gear switch 110 are two movable ports corresponding to the second input port n2. In actual application, when the gear switch 110 is placed in the first gear, a loop can be formed between the external power supply 140, the gear switch 110, and the motor 130, and the motor can work independently. When the gear switch 110 is placed in the second gear, at this time, a loop can be formed between the external power supply 140, the gear switch 110, the motor 130, and the synchronous socket 120 connected to the electric tool, and the motor 130 and the electric tool can work synchronously. When the gear switch is placed in the third gear, the first end c1 and the second end c2 of the motor 130 are disconnected from the external power supply, and the motor is in a non-working state. That is, in the case where the gear switch 110 is placed in the third gear, the connection line between the first end c1 of the external power supply 140 and the motor 130 and the connection line between the second end c2 of the external power supply 140 and the motor 130 can be disconnected at the same time, so that the global power-off of the cleaning device can be realized, which not only ensures the safety of the user, but also reduces the risk of equipment failure.

[0069] In some embodiments, as shown in FIG. 1, the control module can further include: Figure 2

[0070] The motor second end switch circuit 150 connects the second end c2 of the motor 130 to the second output port n4 or the fourth output port n6 of the gear switch 110 through the motor second end switch circuit 150. The motor second end switch circuit 150 connects or disconnects the connection line between the second end c2 of the motor 130 and the second output port n4 or the fourth output port n6 of the gear switch 110 according to the received first control signal.

[0071] ​In actual application, when the gear switch 110 is placed in the first gear, the motor second end switch circuit 150 can keep the connection line between the second end c2 of the motor 130 and the second output end n4 or the fourth output end n6 of the gear switch 110 connected according to the received first control signal. When the gear switch 110 is placed in the second gear, the motor second end switch circuit 150 can disconnect the connection line between the second end c2 of the motor 130 and the second output end n4 or the fourth output end n6 of the gear switch 110 according to the received first control signal, or keep the connection line between the second end c2 of the motor 130 and the second output end n4 or the fourth output end n6 of the gear switch 110 connected. Thus, the connection or disconnection between the second end c2 of the motor 130 and the external power supply 140 can be realized by the motor second end switch circuit 150 when the gear switch 110 is placed in different gears.

[0072] In some embodiments, the motor second end switch circuit 150 can be a transistor switch circuit, such as a Metal Oxide Semiconductor Field Effect Transistor (MOSFET) switch circuit, a bipolar transistor switch circuit, etc., or a relay switch circuit, which is not limited herein.

[0073] Optionally, the first control signal can be a signal input by a user to the motor second end switch circuit 150 through a terminal device (such as a mobile phone, a tablet device, a human-computer interaction device, etc.), or a signal automatically generated based on the detection result of the equipment state of the cleaning device, which is not limited herein. In actual application, the first control signal can be a level signal. As an example, when the first control signal is a high level, the motor second end switch circuit 150 can connect the connection line between the second end c2 of the motor 130 and the second output end n4 or the fourth output end n6 of the gear switch 110. When the first control signal is a low level, the motor second end switch circuit 150 can disconnect the connection line between the second end c2 of the motor 130 and the second output end n4 or the fourth output end n6 of the gear switch 110.

[0074] In some embodiments, as shown in FIG. 1, the control module can further include: Figure 3

[0075] The relay 160, the first end d1 of the relay 160 is connected with the first output end n3 of the gear switch 110; the second end d2 of the relay 160 is connected with the third output end n5 of the gear switch 110; the third end d3 of the relay 160 is connected with the first end c1 of the motor 130.

[0076] ​The relay 160 can connect the first end d1 of the relay 160 to the third end d3 of the relay 160 or connect the second end d2 of the relay 160 to the third end d3 of the relay 160 according to the received second control signal.

[0077] In some embodiments, the second control signal can be determined according to the state of the gear switch, for example, when the gear switch 110 is in the first gear, the second control signal is high, and the connection line between the first end d1 of the relay 160 and the third end d3 of the relay 160 is connected; when the gear switch 110 is in the second gear, the second control signal is low, and the connection line between the second end d2 of the relay 160 and the third end d3 of the relay 160 is connected.

[0078] When the first output end n3 and the third output end n5 of the gear switch 110 are connected to the first end a1 of the external power supply 140, the connection line between the first output end n3 of the gear switch 110 and the first end a1 of the external power supply 140 and the connection line between the second output end n6 of the gear switch 110 and the first end a1 of the external power supply 140 can interfere with each other, for example, the current in one of the above two connection lines can enter the other connection line, resulting in the inability to identify the gear. In this embodiment, by arranging the relay 160 in the control module, and the relay 160 can connect the first end d1 of the relay 160 to the third end d3 of the relay 160 or connect the second end d2 of the relay 160 to the third end d3 of the relay 160 according to the received second control signal, thereby isolating the above two connection lines.

[0079] In some embodiments, as shown in Figure 4 The control module can further include:

[0080] The external tool acquisition circuit 170, wherein the second end b2 of the synchronous socket 120 is connected to the second output end n4 or the fourth output end n6 of the gear switch 110 through the external tool acquisition circuit 170.

[0081] The external tool acquisition circuit 170 is used to acquire the current signal of the synchronous socket 120, and output a corresponding first detection signal according to the sampled current signal, and the first detection signal indicates whether the power tool connected to the synchronous socket 120 is in a working state.

[0082] The first detection signal can be used to generate the first control signal. As an example, if the first detection signal indicates that the power tool connected to the synchronous socket 120 is not in working state, the first control signal for disconnecting the connection line between the second end c2 of the motor 130 and the second output end n4 or the fourth output end n6 of the gear switch 110 can be generated; if the first detection signal indicates that the power tool connected to the synchronous socket 120 is in working state, the first control signal for connecting the connection line between the second end c2 of the motor 130 and the second output end n4 or the fourth output end n6 of the gear switch 110 can be generated. Thus, the first detection signal output by the external tool acquisition circuit 170 can be collected to ensure that the connection line between the external power supply 140 and the second end c2 of the motor 130 can be disconnected when the synchronous socket 120 is not connected to the power tool or the connected power tool is not in working state, so as to realize the synchronous working of the cleaning device and the power tool.

[0083] In some embodiments, as shown in FIG. 1, the external tool acquisition circuit 170 can include a sampling resistor R1 and an operational amplifier U1. Figure 5

[0084] The first end e1 of the external tool acquisition circuit 170 is connected to the second output end u4 or the fourth output end u6 of the gear switch 110, and the second end e2 of the external tool acquisition circuit 170 is connected to the second end b2 of the synchronous socket 120.

[0085] The first end e1 of the external tool acquisition circuit 170 is also connected to the second end e2 of the external tool acquisition circuit 170 through the sampling resistor R1, the second end e2 of the external tool acquisition circuit 170 is also connected to the non-inverting input end of the operational amplifier U1, and the output end of the operational amplifier U1 is connected to the third end e3 of the external tool acquisition circuit 170 to output the first detection signal.

[0086] As an example, in actual application, the second end e2 of the external tool acquisition circuit 170 can be connected to the second end b2 of the synchronous socket 120, and the current signal of the synchronous socket 120 can be collected in combination with the sampling resistor R1, then the collected current signal is amplified by the operational amplifier U1 to obtain the first detection signal, and the first detection signal is output through the third end e3 of the external tool acquisition circuit 170. Thus, the first detection signal can be accurately obtained through the external tool acquisition circuit.

[0087] It can be understood that, in addition to the sampling resistor R1 and the operational amplifier U1, the external tool acquisition circuit 170 can also include auxiliary elements (such as resistors, capacitors, etc.) for ensuring stable working of the tool acquisition circuit 170. Figure 5 ​the auxiliary element (such as the resistor R2, the resistor R5, the capacitor C1, the capacitor C2, etc.) in the circuit shown in FIG. 6, and the connection relationship of the auxiliary element can be referred to the circuit shown in FIG. 6. Figure 5 The details are not described herein.

[0088] In some embodiments, as shown in FIG. 8, the control module can further include a processor 180. Figure 6 The details are not described herein.

[0089] The first end m1 of the processor 180 is connected with the first output end n3 of the gear switch 110 to receive the first gear signal of the gear switch 110; the second end m2 of the processor 180 is connected with the third output end n5 of the gear switch 110 to receive the second gear signal of the gear switch 110; the third end m3 of the processor 180 is connected with the third end e3 of the external tool acquisition circuit 170 to receive the first detection signal of the external tool acquisition circuit 170; the fourth end m4 of the processor 180 is connected with the second end switch circuit 150 to output the first control signal; and the fifth end m5 of the processor 180 is connected with the fourth end d4 of the relay 160 to output the second control signal.

[0090] The first gear signal can represent whether the gear switch 110 is currently placed in the first gear, and as an example, when the first gear signal is a valid level signal (such as a high level), it represents that the gear switch 110 is currently placed in the first gear; and when the first gear signal is a low level, it represents that the gear switch 110 is not currently placed in the first gear. Similarly, the second gear signal can represent whether the gear switch 110 is currently placed in the second gear.

[0091] In actual application, as an example, the processor 180 can generate the second control signal according to the received first gear signal and second gear signal, and send the second control signal to the relay 160 through the fifth end m5 of the processor 180. For example, when the first gear signal received by the processor 180 represents that the gear switch 110 is currently placed in the first gear, and the second gear signal represents that the gear switch 110 is not currently placed in the second gear, the second control signal for turning on the first end d1 of the relay 160 and the third end d3 of the relay 160 can be output to the relay 160. When the first gear signal received by the processor 180 represents that the gear switch 110 is not currently placed in the first gear, and the second gear signal represents that the gear switch 110 is currently placed in the second gear, the second control signal for turning on the second end d2 of the relay 160 and the third end d3 of the relay 160 can be output to the relay 160.

[0092] As another example, the processor 180 can also generate a first control signal according to the received first detection signal, the first gear signal and the second gear signal, and send the first control signal to the motor second end switching circuit 150. For example, when the processor 180 determines that the gear switch 110 is in the second gear according to the received second gear signal, the processor 180 can determine whether the power tool connected to the synchronous socket 120 is in the working state according to the first detection signal. If yes, the processor 180 can generate a first control signal for controlling the motor second end switching circuit 150 to connect the second end c2 of the motor 130 to the second output end n4 or the fourth output end n6 of the gear switch 110. If not, the processor 180 can generate a first control signal for disconnecting the second end c2 of the motor 130 from the second output end n4 or the fourth output end n6 of the gear switch 110.

[0093] Optionally, the processor 180 can be a single-chip microcomputer (MCU), a digital signal controller (DSC), a system-on-chip (SoC), or the like, which is not limited herein.

[0094] In some embodiments, the control module can further include a first zero-crossing detection circuit and a second zero-crossing detection circuit.

[0095] The first output end n3 of the gear switch 110 is connected to the first end m1 of the processor 180 through the first zero-crossing detection circuit. The third output end n5 of the gear switch 110 is connected to the second end m2 of the processor 180 through the second zero-crossing detection circuit.

[0096] In actual applications, the first zero-crossing detection circuit can be used to perform zero-crossing detection processing on the received first gear signal to obtain a first zero-crossing point signal, and send the first zero-crossing point signal to the first end m1 of the processor 180. The second zero-crossing detection circuit can be used to perform zero-crossing detection processing on the received second gear signal to obtain a second zero-crossing point signal, and send the second zero-crossing point signal to the second end m2 of the processor 180.

[0097] The first zero-crossing detection circuit and the second zero-crossing detection circuit are used to convert alternating current signals (such as the first gear signal and the second gear signal) into zero-crossing point signals (such as the first zero-crossing point signal and the second zero-crossing point signal) suitable for processing by the processor 180.

[0098] In some embodiments, as shown in FIG. 1, the control module can further include a first detection circuit and a second detection circuit. Figure 7As shown, the first zero-crossing detection circuit 1300 can include a resistor R6, a resistor R7, and a capacitor C2, wherein a first end of the resistor R7 is connected to the first output end n3 of the gear switch 110 through the resistor R6, and a second end of the resistor R7 is connected to the capacitor C2 and a first end m1 of the processor 180, respectively. In actual applications, the resistor R6 and the resistor R7 are used to reduce the amplitude of the received first gear signal, so as to make it meet the amplitude input range of the processor 180. The capacitor C2 can filter out high-frequency noise in the first gear signal.

[0099] The second zero-crossing detection circuit 1400 can include a resistor R8, a resistor R9, and a capacitor C3, wherein a first end of the resistor R9 is connected to the third output end n5 of the gear switch 110 through the resistor R8, and a second end of the resistor R9 is connected to the capacitor C3 and a second end m2 of the processor 180, respectively. The working principle of the second zero-crossing detection circuit can refer to that of the first zero-crossing detection circuit, and thus will not be described here.

[0100] In some embodiments, as shown, the control module can further include a water level sensor 190. Figure 6

[0101] The sixth end m6 of the processor 180 is connected to the water level sensor 190 to receive a second detection signal of the water level sensor 190.

[0102] In the following, the cleaning device is taken as a dust collector as an example. The second detection signal can represent the water level in the dust bin of the cleaning device.

[0103] In some embodiments, the processor 180 can generate a first control signal according to the received second detection signal.

[0104] In actual applications, the processor 180 can determine whether the water level in the dust bin of the cleaning device meets a preset water level condition according to the received second detection signal. If the preset water level condition is met, the processor 180 can generate a first control signal for controlling the second end switch circuit 150 of the motor to connect the second end c2 of the motor 130 to the second output end n4 or the fourth output end n6 of the gear switch 110. If the preset water level condition is not met, the processor 180 can generate a first control signal for disconnecting the second end c2 of the motor 130 from the second output end n4 or the fourth output end n6 of the gear switch 110.

[0105] Optionally, when the processor 180 determines that the water level in the dust bin is greater than or equal to a water level threshold according to the second detection signal, it can be determined that the water level in the dust bin does not meet the preset water level condition.

The processor 180 can output a high-level second control signal to control the motor 130 to close, and output a low-level second control signal to control the relay 160 to connect the second end d2 of the relay 160 and the third end d3 of the relay 160.

[0121] When the first zero-crossing signal is high, the first detection signal is low, and the second detection signal is high, it indicates that the gear switch 110 is in the second gear, the synchronous socket is connected to the power tool in the working state, and the water level in the dust bucket meets the preset water level condition. The processor 180 can output a high-level second control signal to control the motor 130 to start, and output a high-level second control signal to control the relay 160 to connect the second end d2 of the relay 160 and the third end d3 of the relay 160.

Alternatively, the processor 180 can also detect whether the synchronous socket 120 is connected to the power tool through the first detection signal, and if the synchronous socket 120 is connected to the power tool and the connected power tool is in the working state, the second end c2 of the motor 130 is powered on through the motor second end switch circuit 150, so that the motor 130 starts. If the synchronous socket 120 is not connected to the power tool, the second end c2 of the motor 130 is powered off through the motor second end switch circuit 150, so that the motor 130 is turned off.
