[0083] In order to solve the technical problems existing in the prior art, the embodiments of the present utility model provide an energy control unit, a cleaning machine handle, and a cleaning machine.

[0084] In the embodiments of the present utility model, please refer to Figure 1 、 Figure 2 、Figure 8 As shown in the figure, the energy control unit 1 provided by the embodiment of the present utility model includes a housing 11. The housing 11 has a closed end 11a provided with a plurality of conductive pins, a circumferential side wall (not marked in the attached drawing), and an open end (not marked in the attached drawing). The housing 11 encloses an accommodation cavity 11b from the closed end 11a along the circumferential side wall to the open end. The closed end 11a is used for detachable electrical connection with the handle assembly 2 of the cleaning machine, and a charging interface (not marked in the attached drawing) is externally provided on the handle assembly 2. An energy storage and discharge module 12 and a main control module 13 are installed in the accommodation cavity 11b. A display module 14 is also installed at the open end of the housing 11. Both the display module 14 and the energy storage and discharge module 12 are electrically connected to the main control module 13. The main control module 13 controls the operation of the energy storage and discharge module 12 and the display module 13 in an electrically connected manner.

[0085] Further, in one embodiment, the display module 14 further includes a selection input module 15 for selecting the working mode of the cleaning machine.

[0086] Further, in one embodiment, the selection input module 15 is a touch screen with feedback. The entire display area or a specific area of the touch screen can be triggered for the mode selection function. At this time, the display module 14 and the selection input module 15 are actually the same touch display screen with touch feedback function.

[0087] Further, in one embodiment, as Figure 2 、 Figure 5 、 Figure 8 shown, the display module 14 is a display screen with a circular area hollowed out. The selection input module 15 is a button with a display light that can be pressed to trigger the mode selection and is embedded in the display module 14 and fills the hollowed-out circular area. The part where the display module 14 is connected to the selection input module 15 is a flexible waterproof silicone ring (not marked in the attached drawing) that is integrated with both.

[0088] It should be noted that in this embodiment, the housing 11 can be set to a cylindrical shape, a square tube shape, a stepped square tube shape, or a stepped cylindrical shape. The closed end 11a can be a convex docking head or a concave docking head.

[0089] In one embodiment, as Figures 1 to 3 、 Figures 5 to 7As shown, the closed end 11a of the housing 11 is convexly arranged. When using the cleaning machine, one cleaning machine handle assembly 2 can be adapted to replace multiple energy control units 1. When in use, the energy control unit 1 can be directly plugged into the cleaning machine handle assembly 2. In this embodiment, the detachable electrical connection means that after the closed end 11a is detachably installed on the cleaning machine handle assembly 2, electrical connection can be achieved through the mating of a split conductive connector (not shown in the drawings), and the split conductive connector can specifically be multiple conductive pins (not shown in the drawings). In the embodiment of the present invention, the detachable manner in the detachable electrical connection includes snap connection, magnetic attraction connection, screw connection, etc. The charging and discharging module 12 can include a charging and discharging protection board 121 and a charging battery 124, and the energy control unit 1 can supply power to the cleaning machine via multiple conductive pins of the closed end 11a. The display module 14 can display the real-time voltage of the charging and discharging module 12 collected by the main control module 13. After receiving the corresponding instruction of the selection input module 15, the main control module 13 completes the execution of the corresponding action, including controlling the output power through the charging and discharging module 12, etc. The feedback signal can include the motor speed, real-time power, etc. of the cleaning machine, and the acquisition of the feedback signal can be achieved by setting sensors on the cleaning machine and then transmitting them back to the main control module 13 via multiple conductive pins through the closed end 11a.

[0090] In one of the embodiments, the selection input module 15 can include multiple different function buttons such as a power-on button, a power selection button, a mode selection button, etc.

[0091] In one of the embodiments, as Figure 2 、 Figure 5 、 Figure 8 shown, the selection input module 15 can also be a single function button that enables different functions through different pressing durations, different pressing frequencies, different pressing times at a specific pressing frequency, etc.

[0092] The beneficial effect of the first aspect of the present invention: In the technical solution of the present invention, by setting the energy control unit to be detachably electrically connected to the cleaning machine handle assembly, and integrating the main control module, the charging and discharging module, the display module, and the selection input module on the energy control unit, the remaining power of the energy control unit can be displayed through the display module, the working mode of the cleaning machine can be set through the selection input module, and it is convenient to disassemble and replace the spare energy control unit, facilitating the continuous cleaning operation of the cleaning machine. The selection input module that can be separately pressed independent of the display module can prevent the user's hands from getting wet and causing inflexible touch or misoperation.

[0093] In order to ensure the reliable installation of the energy control unit 1, in one of the embodiments of the present invention, please refer to Figures 2 to 5As shown, at least one clamping portion 111 is provided on the outer surface of the housing 11, and the clamping portion 111 is used to be arranged in cooperation with the buckle assembly 21 of the handle assembly 2. The clamping portion 111 can be a tongue or a groove. The number of the clamping portions 111 is two in this embodiment, that is, two clamping portions 111 are provided on the outer surface of the housing 11.

[0094] Specifically, in this embodiment, please refer to Figures 4 to 6 , each of the clamping portions 111 includes a first guiding boss 1111 extending along the installation direction of the housing 11 and a clamping groove 1112 formed on the first guiding boss 1111. The arrangement of the first guiding boss 1111 and the clamping groove 1112 enables the housing 11 to have a stress-bearing structure with a relatively long length range, and is more durable compared with the cantilever locking tongue structure.

[0095] Specifically, in this embodiment, please further refer to Figures 4 to 6 , the depth of the clamping groove 1112 is gradually increased along the installation direction of the housing 11, and a clamping end face portion 11121 for the buckle assembly 21 to be clamped is provided on the inner wall of the clamping groove 1112. The installation direction of the housing 11 is the direction in which the housing 11 is inserted into the corresponding cleaning machine handle assembly 2. The gradually increasing setting of the clamping groove 1112 in the installation direction facilitates the tongue (not marked in the drawing) of the buckle assembly 21 to slide into the clamping end face portion 11121 to lock the housing 11, and the sliding-in clamping process is a smooth path, reducing the wear of the tongue of the clamping portion 111 on the buckle assembly 21 and improving the service life of the tongue of the corresponding buckle assembly 21 of the cleaning machine.

[0096] In one embodiment of the present utility model, as Figures 3 to 5 shown, the housing 11 is further provided with at least one second guiding boss 112, and the second guiding boss 112 extends in the same direction as the first guiding boss 1111. In this embodiment, the number of the second guiding bosses 112 is one, the number of the clamping portions 111 is set to two, and the number of the corresponding first guiding bosses 1111 is also two. The setting of the second guiding boss 112 together with the first guiding boss 1111 facilitates the installation of the housing 11 to the cleaning machine handle assembly 2, and the shape of the second guiding boss 112 together with the first guiding boss 1111 can form an anti-misoperation structure, so that the energy control unit 1 can be installed to the cleaning machine handle assembly 2 in a set direction each time.

[0097] In order to enhance the connection reliability of the energy control unit 1, in one embodiment of the present utility model, please refer to Figure 2 and Figure 6, the housing 11 is arranged in a stepped contraction shape along the installation direction of the housing 11, and a first abutting end face portion 113, a second abutting end face portion 114, and a third abutting end face portion 115 are sequentially formed. The above settings of the first abutting end face portion 113, the second abutting end face portion 114, and the third abutting end face portion 115 enable the housing 11 and the cleaner handle assembly 2 to have multiple abutting surfaces. The multiple abutting surfaces and the abutting end face portion 11121 where the clamping end face portion 11121 and the clamping component 21 act together limit the housing 11 in the installation direction, increasing the fastening of the installation of the present energy control unit 1 and avoiding power supply interruption to the cleaner caused by the loosening of the electric energy control unit 1.

[0098] In one embodiment of the present invention, as Figure 5 and Figure 7 shown, a conductive transfer convex portion 116 is provided on the circumferential side wall of the housing 11, and the inner end of the conductive transfer convex portion 116 is electrically connected to the charging input end (not shown in the drawing) of the charge and discharge module 12. The conductive transfer convex portion 116 can be used in cooperation with the conductive pin (not shown in the drawing) of the charger (not shown in the drawing) to complete the charging of the energy unit in the charge and discharge module 12.

[0099] In one embodiment of the present invention, please refer to Figure 4 , Figure 8 , Figure 9 , the present energy control unit 1 further includes a transfer board 16. The transfer board 16 is installed on the closed end 11a of the housing 11. The transfer board 16 is provided with a positive conductive pin 161, a negative conductive pin 162, a signal contact pin one 163, a signal contact pin two 164, a signal contact pin three 165, and a signal contact pin four 166. The arrangement of the functional pins of the transfer board 16 can be used in cooperation with the mating jacks at the corresponding positions of the cleaner to form a split conductive part in the detachable electrical connection, and the connection is relatively reliable, ensuring the reliability of the electrical connection in the detachable electrical connection of the present energy control unit 1.

[0100] The beneficial effect of the second aspect of the present invention: The circumferential side wall of the housing of the energy control unit is arranged in a stepped multi-stage contraction shape, and the way that multiple buckles cooperate with the whole energy control unit to buckle into the cleaner handle assembly from small to large in the end face direction improves the electrical connection reliability between the energy control unit and the cleaner handle assembly.

[0101] In one embodiment of the present invention, as Figure 2 , Figures 5 to 8As shown, the display module 14 is an LED display module. The display module 14 is set as an LED display module, with a relatively high display brightness, which can clearly show the power information of the energy control unit to the user. The shape of the display module 14 can be set as the circular shape shown in the figure, or can be set as other shapes. The connection between the display module 14 and the main control module 13 is prior art, and specific reference can be made to relevant prior art.

[0102] In one embodiment of the present invention, as Figure 2 , Figures 5 to 8 shown, the selection input module 15 is a touch button module. It should be noted that the selection input module 15 is selected as a touch button module, which can better isolate external dust and moisture compared with mechanical buttons, and extends the service life of the energy control unit 1 to a certain extent.

[0103] In one embodiment of the present invention, please further refer to Figure 7 and Figure 8 , an end cover 17 is installed at the open end of the housing 11.
