[0057] The existing electric cleaning machine a is powered by battery during working, and the basic cleaning work of a family is completed several times of charging. The existing cleaning machine a charging usually adopts elastic contact electrodes arranged on the base of the cleaning machine a and the charger, and the cleaning machine a starts charging when the matched electrodes are completely contacted. The existing wired cleaning machine a has safety problems such as electric spark ignition and child or pet accidental touch electric shock during charging process; since the existing wired cleaning machine a still stores a certain amount of water in the machine body, the charging contact is generally arranged at the lower part of the wired cleaning machine a, and the leakage during charging process may cause short circuit, and the water dripping and sticking outside the machine body during daily use may also cause corrosion of the charging contact.

[0058] In order to solve the above problems, the application provides a cleaning head.

[0059] In the embodiment of the application, as shown in Figure 1 , Figure 2 and Figure 4 , Figure 1 is a simplified schematic diagram of the cleaning head provided by the application installed on the cleaning machine a, Figure 2 is a cross-sectional schematic diagram of the cleaning head installed on the cleaning head hidden from the power coil, Figure 4 is a simplified schematic diagram of the cleaning head cooperating with the wireless charger.

[0060] The cleaning head 100 is used for the cleaning machine a, and the cleaning machine a can be an unmanned automatic cleaning robot, a handheld mop-sweeper integrated machine, etc., as shown in Figure 1 , the cleaning machine a has a machine shell and a cleaning head 100 installed on the machine shell, the cleaning head 100 has a driving cylinder 200 and a cleaning cylinder 300, the driving cylinder 200 is internally provided with an electric drive module 201 and a wireless charging and discharging module 202 for supplying power to the electric drive module 201, the wireless charging and discharging module 202 is provided with a power receiving coil 204; the cleaning cylinder 300 is sleeved outside the driving cylinder 200 and is in transmission connection with the movement output end of the electric drive module 201; the power receiving coil 204 provided with the wireless charging and discharging module 202 is installed on the driving cylinder 200 or the cleaning cylinder 300. When the power receiving coil 204 is installed on the cleaning cylinder 300, the rotating electrically conductive part installed between the driving cylinder 200 and the cleaning cylinder 300 is electrically connected with the antenna input end of the wireless charging and discharging module 202; when the power receiving coil 204 is installed on the inner wall of the driving cylinder 200, the shell of the driving cylinder 200 is preferably made of insulating magnetic material, such as plastic, etc. Of course, if the wireless charging and discharging module 202 adopts a magnetic resonance type wireless charging mode, the shell of the driving cylinder 200 can also be made of metal material. Since no external connecting line is needed, the two ends of the driving cylinder 200 can be provided with sealing structures to ensure the waterproof property of the electrical structure inside the driving cylinder 200.

[0061] Specifically, as shown in Figure 2 the electric drive module 201 and the wireless charging and discharging module 202 for supplying power to the electric drive module 201 are installed on the drive cylinder 200 of the cleaning head 100, the cleaning cylinder 300 is driven to rotate by the electric drive module 201, and the power receiving coil 204 provided with the wireless charging and discharging module 202 is installed on the drive cylinder 200 or the cleaning cylinder 300. During charging or use, the electrical part of the cleaning machine a can be completely sealed and installed on the drive cylinder 200, avoiding safety problems caused by the exposure of the charging electrode and the connection line of the drive cylinder 200 during use, and increasing the use safety of the cleaning machine a.

[0062] Specifically, as shown in Figure 3 In order to fully couple the power receiving coil 204 with the power transmitting coil b1 of the wireless charger b during charging, in the embodiment of the present application, the power receiving coil 204 is installed on the cleaning cylinder 300 and electrically connected to the power receiving input port in the wireless charging and discharging module 202 through the rotating conductive structure 400. When the cleaning head 100 is installed on the corresponding cleaning machine a, the drive cylinder 200 is used to drive the cleaning cylinder 300 to rotate to adjust the relative position of the power receiving coil 204 and the power transmitting coil b1 of the corresponding wireless charger b of the cleaning machine a. The rotating conductive structure 400 can be a combination of a conductive ring and a conductive needle, or a conductive slip ring 400a can be used. A position sensing switch (not shown in the figure) such as a reed switch can be provided inside the cleaning head 100. After the cleaning head 100 is placed on the corresponding wireless charger b, the position sensing switch sends a switch signal to the control circuit in the electric drive module 201 of the drive cylinder 200 to control the rotation of the drive cylinder 200, that is, the position of the power receiving coil 204 can be adjusted.

[0063] Specifically, in the embodiment of the present application as shown in Figure 3 the rotating conductive structure 400 is a conductive slip ring 400a, the stator end (not shown in the figure) of the conductive slip ring 400a is sleeved on the outer wall of the drive cylinder 200, the rotor end (not shown in the figure) of the conductive slip ring 400a is clamped on the inner wall of the cleaning cylinder 300, the stator end of the conductive slip ring 400a is electrically connected to the power receiving input port in the wireless charging and discharging module 202, and the rotor end is electrically connected to the power receiving coil 204. It should be noted that the conductive slip ring 400a can be a two-input two-output conductive slip ring 400a, or two one-input one-output conductive slip rings 400a. The selection of the conductive slip ring 400a can ensure the reliability of the electrical connection between the power receiving coil 204 installed on the cleaning cylinder 300 and the wireless charging and discharging module 202 after rotation adjustment.

[0064] Specifically, please refer to Figure 3The cleaning head 100 further comprises a first alignment sensor 500 mounted on the driving cylinder 200 and electrically connected to the control circuit of the electric driving module 201, for sending an alignment signal to the electric driving module 201 when the driving cylinder 200 drives the cleaning cylinder 300 to rotate to the position where the power receiving coil 204 is matched with the power transmitting coil b1. The first alignment sensor 500 can be a Hall sensor. When the first alignment sensor 500 is mounted on the shaft cylinder of the cleaning cylinder 300, the electrical connection to the control circuit of the electric driving module 201 can be realized by a rotating conductive structure such as a conductive slip ring (not shown). At this time, a position marker magnet (not shown in the figure) can be arranged on the wireless charger b. When the Hall sensor recognizes the position marker magnet, an alignment signal is sent to the control circuit of the electric driving module 201, and the electric driving module 201 stops driving the cleaning cylinder 300 to rotate. At this time, the power receiving coil 204 on the cleaning cylinder 300 and the power transmitting coil b1 on the wireless charger b are in a preferred coupling position. Of course, the first alignment sensor 500 can also be mounted on the cylinder shell of the driving cylinder. At this time, a position marker magnet can be arranged on the shaft cylinder of the cleaning cylinder 300. When the Hall sensor recognizes the position marker magnet, an alignment signal is sent to the control circuit of the electric driving module 201. The electric driving module 201 stops driving the cleaning cylinder 300 to rotate. At this time, the power receiving coil 204 on the cleaning cylinder 300 and the power transmitting coil b1 on the wireless charger b are in a preferred coupling position. The arrangement of the first alignment sensor 500 in the embodiment of the present application ensures that the driving cylinder 200 can drive the power receiving coil 204 arranged on the cleaning cylinder 300 to rotate to a preferred coupling position with the power receiving coil 204 of the wireless charger b, thereby ensuring that the charging efficiency of the wireless charger b on the cleaning head 100 is a preferred charging efficiency.

[0065] Specifically, in another embodiment of the present application, please refer to Figure 5The power receiving coil 204 is installed on the driving cylinder 200. When the cleaning head 100 is installed on the corresponding cleaning machine a, the power receiving coil 204 is arranged in a matching position with the power transmitting coil b1 of the corresponding wireless charger b of the cleaning machine a. The matching arrangement of the power receiving coil 204 with the power transmitting coil b1 of the corresponding wireless charger b of the cleaning machine a can be achieved by installing positioning structures on both ends of the driving cylinder 200. That is, when the cleaning head 100 is installed on the shell of the cleaning machine a, the positioning structures ensure that the position of the driving cylinder 200 relative to the shell of the cleaning machine a is fixed. At this time, as long as the power receiving coil 204 is installed on the driving cylinder 200 in a position corresponding to the power transmitting coil b1 in advance, the matching arrangement can be achieved. The positioning structures can be a combination of positioning ribs and positioning grooves or other structures. The matching arrangement of the power receiving coil 204 with the power transmitting coil b1 of the corresponding wireless charger b of the cleaning machine a can ensure that the power receiving coil 204 is installed on the driving cylinder 200 and is not affected by the rotation of the cleaning cylinder 300, and can ensure that the power receiving coil 204 can be coupled with the wireless charger b when charging.

[0066] Specifically, in the embodiment of the present application, please further refer to Figure 5 The power receiving coil 204 is installed on the driving cylinder 200, and the driving cylinder 200 is provided with an electric rotation adjusting mechanism 203 driven by a driving unit of the electric driving module 201. The electric rotation adjusting mechanism 203 is used to drive the driving cylinder 200 to rotate. The electric rotation adjusting mechanism 203 can be a combination of a motor and a gear structure, or a motor rotating arm structure, etc. As shown in the figure, it is a motor gear structure. The motor can be fixed on the fixed shaft of the driving cylinder 200. The motor drives the gear set to drive the cylinder shell 200 to rotate, and then the movement of the power receiving coil 204 installed on the shell of the driving cylinder 200 can be adjusted to adjust the coupling position of the power receiving coil 204 and the power transmitting coil b1 of the wireless charger b.

[0067] Specifically, please refer to Figures 5 to 7 The cleaning head 100 further comprises a second alignment sensor 600, which is electrically connected with a control circuit signal input end (not marked in the figure) of the electric driving module (201), Figure 5The second alignment sensor 600 is installed on the driving cylinder 200, and is used to send an alignment signal to the electric driving module 201 when the position of the power receiving coil 204 on the driving cylinder 200 is aligned with the position of the power transmitting coil b1 of the corresponding wireless charger b of the cleaning machine a. The second alignment sensor 600 can be a Hall sensor, and a position marker magnet can be arranged on the wireless charger b. When the Hall sensor identifies the position marker magnet, an alignment signal is sent to the control circuit of the electric driving module 201, and the electric driving module 201 stops driving the electric rotation adjusting mechanism 203 to drive the driving cylinder 200 to rotate. At this time, the position of the power receiving coil 204 on the driving cylinder 200 is in a preferred coupling position with the position of the power transmitting coil b1 on the wireless charger b. In the embodiment of the present application, the arrangement of the second alignment sensor 600 ensures that the electric rotation adjusting mechanism 203 can more accurately rotate the power receiving coil 204 arranged on the driving cylinder 200 to a preferred coupling position with the power receiving coil 204 of the wireless charger b, and ensures that the charging efficiency of the wireless charger b on the cleaning head 100 is a preferred charging efficiency.

[0068] As a further improved embodiment, the first alignment sensor 500 and the second alignment sensor 600 can be arranged on the driving cylinder 200 at the same time. Only when both sensors send an alignment signal, the electric driving module 201 stops driving the electric rotation adjusting mechanism 203 to drive the driving cylinder 200 to rotate. At this time, the position of the power receiving coil 204 on the driving cylinder 200 is in a preferred coupling position with the position of the power transmitting coil b1 on the wireless charger b. This scheme can prevent misjudgment in the case of failure of a single sensor, which causes the position of the power receiving coil 204 on the driving cylinder 200 to be unable to be in a preferred coupling position with the position of the power transmitting coil b1 on the wireless charger b.

[0069] As a further improved embodiment, more than two alignment sensors (not shown in the figure) can be arranged on the driving cylinder 200 at the same time. Through a software algorithm, only when a certain number of sensors in the multiple sensors send an alignment signal, the electric driving module 201 stops driving the electric rotation adjusting mechanism 203 to drive the driving cylinder 200 to rotate. At this time, the position of the power receiving coil 204 on the driving cylinder 200 is in a preferred coupling position with the position of the power transmitting coil b1 on the wireless charger b. This scheme can prevent misjudgment in the case of failure of a certain number of sensors, which causes the position of the power receiving coil 204 on the driving cylinder 200 to be unable to be in a preferred coupling position with the position of the power transmitting coil b1 on the wireless charger b.

[0070] Specifically, as Figure 2As shown, the electric drive module 201 comprises a driver 2011, a drive motor 2012, a speed changer 2013 and a transmission 2014. The power output end of the wireless charging and discharging module 202 is electrically connected with the power supply end of the driver 2011. The power output end is electrically connected with the drive motor 2012. The input end of the speed changer 2013 is connected with the rotating shaft of the drive motor 2012. The output end of the speed changer 2013 is drivingly connected with the input end of the transmission 2014. The output end of the transmission 2014 is drivingly connected with the cleaning barrel 300.
