Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0040] like Figures 1 to 10 As shown, the present application provides a battery assembly. This battery assembly is used at least in a main unit 11 of a cleaning device and includes a mounting housing 10, a battery pack 20, and a snap assembly 30. The mounting housing 10 is fixed to the main unit 11 and is provided with a mounting cavity 12. The battery pack 20 is removably mounted in the mounting cavity 12. The snap assembly 30 is disposed between the mounting housing 10 and the battery pack 20. The snap assembly 30 has a locking position for securing the battery pack 20 within the mounting cavity 12 and an unlocking position for releasing the battery pack 20.

[0041] In this embodiment, the battery pack 20 can be removed from the main body 11 of the cleaning device by controlling the buckle assembly 30. When the buckle assembly 30 is in the locked position, the battery pack 20 is locked in the installation cavity 12, and the battery pack 20 can supply power to the cleaning device and provide power for the operation of the cleaning device. When the buckle assembly 30 is in the unlocked position, the user can remove the battery pack 20 from the installation cavity 12 and replace it with another battery pack 20 with sufficient power. When the cleaning device is used for a long time, when the battery pack 20 in the installation cavity 12 is exhausted, the user can remove the battery pack 20 and replace it with a spare battery pack 20 with sufficient power, which effectively improves the endurance of the cleaning device. The user does not need to wait for charging time, which can improve the efficiency and flexibility of the cleaning device, meet the user's needs for efficient and continuous cleaning, and help improve the user experience. At the same time, the detachability of the battery pack 20 also facilitates the maintenance of the connection lines in the installation cavity 12, which can improve the endurance of the cleaning device and extend the service life of the cleaning device.

[0042] Among them, the mounting shell 10 is fixedly installed inside the outer shell of the host 11. The host 11 can protect the battery pack 20 and the connection lines between the battery pack 20 and the host 11 from pollution and damage from the external environment, thereby extending the service life of the battery pack 20.

[0043] like Figures 1 to 7 As shown, further, the snap assembly 30 includes a locking component 31 and a pressing component 32. The locking component 31 is connected to the mounting shell 10, and the locking component 31 has a locking position and an unlocking position. The pressing component 32 is connected to the locking component 31, and the pressing component 32 drives the locking component 31 to switch between the locking position and the unlocking position under the action of an external force. After the pressing component 32 is subjected to an external force applied by the user, the pressing component 32 can drive the locking component 31 to switch between the locking position and the unlocking position, so that the battery pack 20 is locked in the mounting cavity 12 or the battery pack 20 is released. The user can easily lock and unlock the battery pack 20 by simply pressing the pressing component 32. This arrangement makes the locking and unlocking operations of the battery pack 20 simpler and more convenient, which is conducive to improving the ease of use of the cleaning device.

[0044] Furthermore, a locking fitting portion 21 is provided on the outer wall of the battery pack 20. The locking component 31 includes a locking member 311. The middle of the locking member 311 is rotatably connected to the mounting shell 10 via a rotating shaft 312. One end of the locking member 311 is provided with a locking portion 313 for cooperating with the locking fitting portion 21, and the other end is driven by the pressing member 32 to rotate and drive the locking portion 313 to engage or separate with the locking fitting portion 21. When the user does not apply external force to the pressing member 32, the locking portion 313 and the locking fitting portion 21 remain tightly engaged, and the locking portion 313 locks the mounting package in the mounting cavity 12. When the user needs to disassemble the battery pack 20, the user can apply external force to the pressing member 32, and the pressing member 32 can drive the end of the locking member 311 away from the locking portion 313 to rotate around the rotating shaft 312. At the same time, the locking portion 313 also rotates accordingly and separates from the locking engagement portion 21, allowing the user to remove the battery pack 20 from the installation cavity 12. After the battery pack 20 is removed from the installation cavity 12, the user removes the external force, and the locking member 311 rotates around the rotation axis 312 to return to the locked position. To reinstall the battery pack 20, the user simply presses the pressing member 32 again to move the locking portion 313 away from the installation cavity 12, then places the battery pack 20 into the installation cavity 12. Finally, release the pressing member 32 to engage the locking portion 313 with the locking engagement portion 21, locking the battery pack 20 securely in the installation cavity 12.

[0045] Furthermore, the locking member 311 is in a strip-shaped structure. The middle of the strip-shaped structure is sleeved on the rotating shaft 312, the strip-shaped structure extends into the mounting cavity 12, and the locking portion 313 is located at the end of the strip-shaped structure close to the battery pack 20. The locking member 311 with a strip-shaped structure can save installation space inside the host 11, making the structure of the host 11 more compact, and helping to reduce the volume of the host 11. Specifically, the locking member 311 can be configured as a torsion spring member, the middle part of the torsion spring member is sleeved on the rotating shaft 312, so that the torsion spring member is rotatably connected to the mounting shell 10. It can be understood that the specific structure of the locking member 311 is not limited to this, and this embodiment does not make the sole limitation.

[0046] The outer wall of the mounting housing 10 is provided with a locking through-hole 13. The end of the strip structure, which is closest to the battery pack 20, can extend into the locking through-hole 13 and pass through the locking through-hole 13 into the mounting cavity 12. The other end of the strip structure, which is further away from the battery pack 20, extends to the vicinity of the pressing member. When subjected to an external force, the pressing member can contact the other end of the strip structure, which is further away from the battery pack 20, and drive the strip structure to rotate.

[0047] The locking member 311 has a through-hole in its center, into which the rotating shaft 312 passes. The outer wall of the mounting housing 10 also has a mounting slot, into which the through-hole is located. The inner wall of the mounting slot has two opposing through-holes, through which the rotating shaft 312 passes, securing the locking member 311 to the mounting housing 10. The locking member 311 can also rotate relative to the mounting housing 10 and switch between a locked and unlocked position, locking or releasing the battery pack 20 within the mounting cavity 12.

[0048] Furthermore, the locking fitting portion 21 includes a locking slot 211, and the locking portion 313 includes a locking tongue 3131. The locking tongue 3131 is connected to the end of the strip structure close to the battery pack 20. A snap-fit surface 3132 is provided on the locking tongue 3131, and the snap-fit surface 3132 abuts against the inner side wall of the locking slot 211 to lock the battery pack 20 in the installation cavity 12. By applying an external force to the pressing component 32, the locking tongue 3131 can be rotated under the drive of the pressing component 32. During the rotation of the locking tongue 3131, when the locking tongue 3131 moves away from the battery pack 20, the locking tongue 3131 separates from the locking slot 211, and the user can remove the battery pack 20 from the installation cavity 12. When the external force is removed, the locking tongue 3131 rotates closer to the battery pack 20, and the engaging surface 3132 of the locking tongue 3131 abuts the inner sidewall of the locking slot 211, securing and locking the battery pack 20 within the mounting cavity 12. The tight engagement of the engaging surface 3132 with the inner sidewall of the locking slot 211 ensures the stability of the battery pack 20 within the mounting cavity 12, maintains the stability of the electrical connection between the battery pack 20 and the motor, and contributes to the reliable operation of the host 11. In this embodiment, the engagement of the engaging surface 3132 with the inner sidewall of the locking slot 211 secures the battery pack 20 and ensures its stability. The locking tongue 3131 is also provided with a guide surface. The guide surface can be set on the side of the lock tongue 3131 away from the locking surface 3132. The guide surface is used to ensure that the lock tongue 3131 can smoothly enter the lock groove 211 and ensure that the locking surface 3132 can tightly abut against the inner side wall of the lock groove 211.

[0049] Furthermore, the pressing component 32 includes a button 321. The button 321 extends through the mounting housing 10 and is movable relative to the mounting housing 10. When subjected to an external force, the button 321 abuts against the locking member 311, causing the locking member 311 to rotate away from the locking portion 313. The user can lock and unlock the battery pack 20 by simply pressing the button 321. This intuitive operation is simpler and significantly enhances the user experience. The pressing component 32 may also be provided with a feedback mechanism. When the user presses the button 321, this feedback mechanism provides audible feedback or a tactile sensation, ensuring that the user can intuitively determine the status of the locking member 311 and enhancing the user experience. Specifically, when the user presses the button 321, the button 321 causes the locking member 311 to rotate away from the end of the battery pack 20. The locking tongue 3131 also rotates away from the locking slot 211, unlocking the battery pack 20 and allowing the user to remove the battery pack 20 from the mounting cavity 12.

[0050] like Figures 8 and 9 As shown, the battery assembly further includes a limiting component 40. The limiting component 40 is disposed between the outer side wall of the battery pack 20 and the inner side wall of the installation cavity 12. The limiting component 40 is used to limit the battery pack 20 so that the locking portion 313 cooperates with the locking mating portion 21. The limiting component 40 can limit the battery pack 20 to be installed at a predetermined position in the installation cavity 12. Only when the battery pack 20 is in the predetermined position can the locking portion 313 accurately cooperate with the locking mating portion 21. The limiting component 40 can provide an installation guide for the user, guiding the user to accurately install the battery pack 20 to the predetermined position.

[0051] Furthermore, the limiting component 40 also includes a strip-shaped protrusion 41 and a strip-shaped groove 42. The strip-shaped protrusion 41 cooperates with the strip-shaped groove 42. One of the strip-shaped protrusion 41 and the strip-shaped groove 42 is provided on the outer wall of the battery pack 20, and the other is provided on the inner wall of the mounting cavity 12, and the strip-shaped protrusion 41 and the strip-shaped groove 42 extend along the installation direction of the battery pack 20 into the mounting cavity 12. The mutual cooperation between the strip-shaped protrusion 41 and the strip-shaped groove 42 provides a precise guide for the installation of the battery pack 20. When installing the battery pack 20, the user only needs to align the strip-shaped protrusion 41 with the strip-shaped groove 42 and push it in along its extension direction to ensure that the battery pack 20 is installed in the correct position and angle, effectively ensuring that the battery pack 20 is accurately installed in the predetermined position. At the same time, the strip-shaped protrusion 41 and the strip-shaped groove 42 can further limit the battery pack 20 to prevent the battery pack 20 from rotating along its own circumferential direction.

[0052] The end of the main unit 11 is provided with a handle 111, and the user holds the handle 111 to facilitate pushing and pulling the main unit 11 for cleaning. The end of the main unit 11 away from the handle 111 is also provided with a cleaning member 112, which is used to clean the floor.

[0053] On the other hand, Figures 1 to 10 As shown, an embodiment of the present application also provides a cleaning device, which includes a host 11 and a base station 50. The host 11 is provided with a battery assembly. The host 11 is detachably mounted on the base station 50. When the host 11 and the base station 50 cooperate, the base station 50 can pump the garbage and sewage in the sewage tank of the host 11 into the sewage collection tank of the base station 50, and finally discharge the garbage and sewage in the sewage collection tank into the sewer. The cleaning device includes all the technical effects of the above-mentioned battery assembly. Since the technical effects of the battery assembly have been described in detail above, they will not be repeated here.

[0054] Furthermore, the base station 50 is provided with a charging chamber 51. The charging chamber 51 is used to charge the battery pack 20. When the battery pack 20 in the host 11 is low on power, the user can remove the battery pack 20 and place it in the charging chamber 51 of the base station 50 for charging. The charging chamber 51 in the base station 50 also provides storage space for the battery pack 20.

[0055] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0056] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.

[0057] The above are merely preferred embodiments of the present application and are not intended to limit the present application. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
