[0069] In order to solve the technical problems existing in the prior art, an embodiment of the present invention provides a cleaning machine battery device and a cleaning machine handle.

[0070] In the embodiment of the present invention, please refer to Figure 1 and Figure 8 As shown, the battery device 1 provided in an embodiment of the present invention includes a battery device shell 11, having a connection end 11a and a accommodating cavity 11b, wherein the connection end 11a is used for detachable electrical connection with the cleaning machine handle 2; a charging and discharging module 12 and a main control module 13 are installed in the accommodating cavity 11b; the battery device shell 11 is also provided with a display module 14 and a selection input module 15; the display module 14, the selection input module 15 and the charging and discharging module 12 are all electrically connected to the main control module 13 to supply power to the cleaning machine handle 2 via the connection end 11a and receive and process feedback signals transmitted back from the cleaning machine handle 2.

[0071] It should be noted that in this embodiment, the battery device housing 11 can be provided in a cylindrical shape, a square cylindrical shape, a stepped square cylindrical shape or a stepped cylindrical shape, and the connecting end 11a can be a convex butt joint or a concave butt joint. In this embodiment, Figure 1 and Figure 2As shown, the connection end 11a of the battery device housing 11 is convexly arranged. When the cleaning machine is in use, one cleaning machine handle 2 can be adapted to replace multiple battery devices 1. The battery device 1 can be directly plugged into the cleaning machine handle 2 when in use. In this embodiment, the detachable electrical connection means that after the connection end 11a is detachably installed on the cleaning machine handle 2, electrical connection can be achieved by matching a split conductive connector (not shown in the drawings). The detachable methods of the detachable electrical connection described in the embodiment of the present invention include snap connections, magnetic connections, threaded connections, etc. The charging and discharging module 12 may include a charging and discharging protection plate 121 and a rechargeable battery 124, and the battery device 1 can power the cleaning machine via the split conductive connector of the connection end 11a. The display module 14 can display the real-time voltage of the charge-discharge module 12 collected by the main control module 13. The selection input module 15 can include one or more different function keys, such as a power button and a power selection key. When there is only one function key, the functions that can only be achieved by multiple function keys can be realized by controlling the duration of holding the key, the number of consecutive presses of a specific frequency, the speed of consecutive presses of the specific frequency, and other dimensions. After receiving the corresponding instructions from the selection input module 15, the main control module 13 completes the corresponding actions, including controlling the output power through the charge-discharge module 12. The feedback signal may include the motor speed and real-time power of the cleaning machine. The feedback signal can be collected by a sensor installed on the cleaning machine and then transmitted back to the main control module 13 via the connection terminal 11a through a separate electrical connector.

[0072] Beneficial effects of the present invention: The technical solution of the present invention is to set the battery device 1 to be detachably electrically connected to the cleaning machine handle 2, and integrate the main control module 13, the charging and discharging module 12, the display module 14 and the selection input module 15 on the battery device 1. The remaining power of the battery device 1 can be displayed through the display module 14, and the working mode of the cleaning machine can be set through the selection input module 15. It is also convenient to disassemble and replace the spare battery device 1, so that the cleaning machine can be used to continuously perform cleaning operations.

[0073] In order to ensure reliable installation of the battery device 1, in one embodiment of the present invention, please refer to Figures 2 to 5As shown, the outer surface of the battery device housing 11 is provided with at least one clamping portion 111, and the clamping portion 111 extends from one end of the battery device housing 11 to the middle of the other end facing the opposite end, and the clamping portion 111 is used to match the buckle assembly 21 of the cleaning machine handle 2. The clamping portion 111 can be a latch or a slot. The number of the at least one clamping portion 111 in this embodiment is two, that is, the clamping portion 111 is provided with two opposite ones on the outer surface of the battery device housing 11. As needed, the number of the at least one clamping portion 111 can also be set to three, that is, the clamping portion 111 is provided with three evenly distributed ones on the outer surface of the battery device housing 11. As needed, the number of the at least one clamping portion 111 can also be set to four, that is, the clamping portion 111 is provided with four evenly distributed ones on the outer surface of the battery device housing 11.

[0074] Specifically, in one embodiment of the present invention, please refer to Figures 4 to 6 Each of the engaging portions 111 includes a first guide protrusion 1111 extending along the installation direction of the battery housing 11 and an engaging slot 1112 formed on the first guide protrusion 1111. The arrangement of the first guide protrusion 1111 and the engaging slot 1112 provides the battery housing 11 with a stress-bearing structure over a longer length, making it more durable than a cantilevered latch structure.

[0075] Specifically, in this embodiment, please refer to Figures 4 to 6 The depth of the engaging groove 1112 is gradually deepened along the installation direction of the battery device housing 11, and an engaging end surface portion 11121 for engaging the snap assembly 21 is provided on the inner wall of the engaging groove 1112. The installation direction of the battery device housing 11 is the direction in which the battery device housing 11 is inserted into the handle assembly 2 of the corresponding cleaning machine. The gradually deepening arrangement of the engaging groove 1112 in the installation direction facilitates the sliding of the latch tongue (not shown in the drawings) of the snap assembly 21 into the engaging end surface portion 11121 to lock the battery device housing 11. The sliding and engaging process is a smooth path, reducing wear on the latch tongue of the snap assembly 21 caused by the engaging portion 111, thereby increasing the service life of the latch tongue of the corresponding snap assembly 21 of the cleaning machine.

[0076] In one embodiment of the present invention, Figures 3 to 5As shown, the battery device housing 11 is further provided with at least one second guide protrusion 112. The second guide protrusion 112 extends in the same direction as the first guide protrusion 1111. The second guide protrusion 112 extends from one end of the battery device housing 11 to the opposite end. In this embodiment, there is one second guide protrusion 112, and the number of the clamping portions 111 is set to two, corresponding to the number of the first guide protrusions 1111 being two. The provision of the second guide protrusion 112 together with the first guide protrusion 1111 facilitates the installation of the battery device housing 11 to the cleaning machine handle 2. The shape of the second guide protrusion 112 together with the first guide protrusion 1111 can form a fool-proof structure, allowing the battery device 1 to be installed on the cleaning machine handle 2 in the set direction each time. If desired, the number of second guide protrusions 112 can also be set to two, that is, two second guide protrusions 112 are evenly distributed on the outer surface of the battery device housing 11. As needed, the number of the second guide bosses 112 can also be set to three, that is, three second guide bosses 112 are evenly distributed on the outer surface of the battery device housing 11 .

[0077] In order to enhance the connection reliability of the battery device 1, in one embodiment of the present invention, please refer to Figure 2 and Figure 6 The battery device housing 11 is arranged in a stepped contraction shape along the installation direction of the battery device housing 11, and is sequentially formed with a first abutting end surface portion 113, a second abutting end surface portion 114, and a third abutting end surface portion 115. The battery device housing 11 has a single cross-section cylindrical shape between every two adjacent abutting end surface portions (for example, the battery device housing 11 can be set to a cylindrical shape, a square cylindrical shape, a stepped square cylindrical shape, or a stepped cylindrical shape). The single cross-section cylindrical shape can also be a regular polygonal cylindrical shape, a regular cross-section cylindrical shape, or an irregular single cross-section cylindrical shape. The battery device shell 11 is arranged in a stepped contraction shape along the installation direction of the battery device shell 11, so that after the battery device 1 is installed in the cleaning machine handle 2, the entire battery device shell 11 formed by multiple single-section cylindrical structures is not prone to radial loosening perpendicular to the central axis along the entire central axis. The above arrangement of the first abutting end surface 113, the second abutting end surface 114, and the third abutting end surface 115 allows the battery device shell 11 and the handle assembly 2 of the cleaning machine to have multiple abutting surfaces. The multiple abutting surfaces and the snapping end surface 11121 and the snapping end surface 11121 of the snap assembly 21 together limit the battery device shell 11 in the installation direction, so that the fastening cooperation between the battery device 1 and the cleaning machine handle 2 in both the radial and axial directions of the central axis is well limited, thereby increasing the tightness of the installation of the battery device shell 11 and avoiding the interruption of power supply to the cleaning machine due to the loosening of the battery device shell 11.

[0078] In one embodiment of the present invention, Figure 5 、 Figure 8 and Figure 9 As shown, the outer surface of the battery housing 11 is provided with a conductive adapter protrusion 116. The inner end of the conductive adapter protrusion 116 (not shown) is electrically connected to the charging input terminal (not shown) of the charging and discharging module 12. The conductive adapter protrusion 116 can be used in conjunction with the conductive pins of the charger to charge the rechargeable battery 124 in the charging and discharging module 12.

[0079] Specifically, in one embodiment of the present invention, please refer to Figure 4 、 Figure 8 and Figure 9 As shown, the battery device 1 also includes an adapter plate 16, which is mounted on the connection end 11a of the battery device housing 11. The adapter plate 16 is provided with a positive conductive pin 161, a negative conductive pin 162, a signal contact pin 1 163, a signal contact pin 2 164, a signal contact pin 3 165, and a signal contact pin 4 166. The functional pins on the adapter plate 16 can be used in conjunction with corresponding mating sockets on the cleaning machine to form a separate conductive connector for the removable electrical connection. This provides a relatively secure connection and ensures the reliability of the removable electrical connection of the battery device 1.

[0080] Specifically, in one embodiment of the present invention, Figure 7 and Figure 8 As shown, the display module 14 is an LED display module. The display module 14 is configured as an LED display module with high brightness, clearly displaying the battery status information of the battery device 1 to the user. The shape of the display module 14 can be circular as shown in the figure, or other shapes. The connection between the display module 14 and the main control module 13 is conventional, and reference can be made to the relevant prior art for details.

[0081] In one embodiment of the present invention, Figure 7 and Figure 8 As shown, the selection input module 15 is a touch key module. It should be noted that the selection input module 15 is a touch key module, which, compared to mechanical keys, can better isolate external dust and moisture, thereby extending the service life of the battery device 1 to a certain extent. Furthermore, the touch key module includes multiple touch keys, which are virtual keys of the display module 14 or physical keys embedded in the display module 14.

[0082] Specifically, in one embodiment of the present invention, please refer to Figure 7 and Figure 8In this embodiment, a protective end cap 17 is installed on the battery device housing 11 away from the connection end 11a. When maintenance or replacement of the internal components of the battery device 1 is required, the protective end cap 17 must first be removed, and then the internal components of the battery device 1 are removed in sequence. The provision of the protective end cap 17 facilitates installation of the components of the battery device 1 and makes maintenance easier, thereby reducing production and maintenance costs to a certain extent.

[0083] In order to improve the sealing performance of the battery device 1, in one embodiment of the present invention, as shown in FIG. Figure 7 As shown, a sealing ring 171 is provided at the installation position of the protective end cover 17. The provision of the sealing ring 171 enhances the waterproof and dustproof properties of the protective end cover 17.

[0084] Please see further Figure 7 In one embodiment of the present invention, the display module 14 and the selection input module 15 are embedded in the protective end cover 17.
