[0042] This disclosure provides a charging device 10, a cleaning base station, and a cleaning system. The charging device 10 and the base station body 20 cooperate to form a cleaning base station, and the cleaning base station and the cleaning host cooperate to form a cleaning system. The cleaning system includes the aforementioned cleaning base station with the charging device 10, and also includes a cleaning host with a roller brush and / or mop, etc. The cleaning system can be a mopping robot, a sweeping robot, or a floor scrubber, etc., with a base station and capable of mopping. The corresponding cleaning host can be a mopping robot host, a sweeping robot host, or a floor scrubber host, etc., which has sweeping and / or mopping functions. It is understood that the cleaning host is provided with charging components for charging, such as contacts. When the cleaning host is located within the receiving cavity 220 of the cleaning base station, the charging device 10 located on the cleaning base station can be electrically connected to the charging components on the cleaning host to charge the cleaning host.

[0043] The cleaning host can be a device that automatically performs cleaning operations in a specific area to be cleaned. The cleaning base station is used at least to charge the cleaning host. For example, when the cleaning host starts working, it can depart from the cleaning base station and execute the corresponding cleaning task; when the cleaning host completes the cleaning task or needs to be recharged, it can return to the cleaning base station for charging. Of course, the cleaning base station can also provide other maintenance functions for the cleaning host besides charging, such as washing the mop on the cleaning host, charging the cleaning host, replenishing water, and collecting dust. When the cleaning host starts working, it can depart from the cleaning base station and execute the corresponding cleaning task; when the cleaning host completes the cleaning task or in other situations where the cleaning task needs to be stopped, it can return to the cleaning base station to perform at least one or more of the following tasks: charging, replenishing water, washing, and collecting dust.

[0044] The cleaning base station includes a base station body 20 and a charging device 10. The base station body has a mounting base 210 and a receiving cavity 220 for accommodating the cleaning unit. The charging device 10 is mounted on the mounting base 210 and is movable relative to the receiving cavity 220 between a first position and a second position. When the cleaning unit moves into the receiving cavity of the base station body 20, an external force can be applied to the charging device 10, causing the charging device 10 to move from the first position toward the second position. When the charging device 10 moves to the second position, it can be electrically connected to the charging component of the cleaning unit to charge the cleaning unit.

[0045] Figure 1 is a structural schematic diagram of the charging device 10 provided in the embodiment of this disclosure, Figure 2 is an installation schematic diagram of the charging device 10 provided in the embodiment of this disclosure, Figure 3 is an exploded view of the charging device 10 provided in the embodiment of this disclosure, Figure 4 is a structural schematic diagram of the charging component 1 in the charging device 10 provided in the embodiment of this disclosure, and Figure 5 is an exploded view of the charging component 1 provided in the embodiment of this disclosure.

[0046] Please refer to Figure 1. This embodiment of the present disclosure provides a charging device 10, which can be installed on a cleaning base station to charge the cleaning host that is associated with the cleaning base station.

[0047] Specifically, the charging device 10 includes a charging component 1 and an elastic element 2. The charging component 1 is movably mounted on the installation position. The elastic element 2 includes a fixed end 201 and a follower end 202. The fixed end 201 is fixedly mounted relative to the moving end of the charging component 1, and the follower end 202 is disposed on the charging component 1 and can move synchronously with the movement of the charging component 1. When the charging component 1 is driven by an external force and moves, the follower end 202 of the elastic element 2 moves synchronously and undergoes elastic deformation in this process. When the external force is removed, the elastic element 2 returns to its original shape and can drive the charging component 1 to move to the initial position.

[0048] In some embodiments, the charging component 1 can be mounted on the installation position via the movable shaft 3.

[0049] In some embodiments, the elastic element 2 may be a torsion spring structure, as shown in FIG1. ​​The torsion spring includes a spring body 21, a fixed torsion arm 22 and a follower torsion arm 23, wherein the fixed torsion arm 22 has the fixed end 201, the follower torsion arm 23 has the follower end 202, and the spring body 21 may be sleeved on the movable shaft 3.

[0050] Please refer to Figure 1. The spring body 21 is connected to the moving shaft 3, the follower torsion arm 23 is connected to the charging component 1, and the fixed torsion arm 22 is fixedly installed relative to the moving shaft 3. Under the drive of an external force, the charging component 1 moves from the first position to the second position, and in this process, it drives the follower torsion arm 23 to move synchronously and approach the fixed torsion arm 22. At this time, the spring body 21 undergoes elastic deformation. When the external force is removed, the spring body 21 can return to its initial shape under the action of elasticity. At this time, the follower torsion arm 23 can drive the charging component 1 back to the initial position, i.e., the first position.

[0051] It should be noted that, along the axial direction of the torsion spring (that is, along the axial direction of the spring body 21), the projection of the fixed torsion arm 22 and the projection of the follower torsion arm 23 do not intersect, and their orthogonal projections along the axial direction of the torsion spring are spaced apart. In other words, the fixed torsion arm 22 and the follower torsion arm 23 are located on both sides of the spring body 21.

[0052] When the size of the charging device 10 needs to be adjusted, only the size of the moving arm of the charging component 1 needs to be adjusted, and the specifications of the torsion spring need to be adjusted accordingly to allow the charging component 1 to move normally. Compared with related structures, the charging device 10 provided in this embodiment is more flexible in size range. When the installation space of the charging device 10 is limited, this embodiment can achieve miniaturization of the charging device 10 by shortening the moving arm of the charging component 1 without changing the basic shape of the elastic element 2, thereby reducing the space occupation of the charging device 10 in the clean base station.

[0053] Please refer to Figure 2 when installing the charging component 1 onto the mounting base 210 of the cleaning base station. In the figure, the cleaning base station is positioned between the first and second positions.

[0054] The fixed torsion arm 22 and the follower torsion arm 23 of the aforementioned torsion spring have an L-shaped or similar L-shaped structure. Referring to Figure 2, in the axial projection direction of the moving shaft 3, the portion of the fixed torsion arm 22 connected to the spring body 21 and the portion of the follower torsion arm 23 connected to the spring body 21 have an angle in that direction, and this angle is an acute angle.

[0055] Specifically, the included angle can be set to a range of 60°-85°, and its specific value can be adaptively adjusted within this range according to design needs. For example, the included angle can take any value from 60°, 65°, 70°, 75°, 80°, and 85°.

[0056] Referring to Figures 1 and 2, it can be seen that when the charging device 10 is installed on the mounting base 210, the moving shaft 3 and the fixed torsion arm 22 of the torsion spring are located at fixed positions on the mounting base 210, and there is a certain gap between the moving shaft 3 and the fixed torsion spring. The moving end of the charging component 1 can be connected to the moving shaft 3 by being sleeved on the moving shaft 3. When the charging component 1 is squeezed by an external force and moves towards the second position, the included angle formed between the fixed torsion arm 22 and the follower torsion arm 23 gradually decreases.

[0057] The structure of the charging device 10 will be further explained below:

[0058] Please refer to Figure 3. The charging device 10 mentioned above includes a charging component 1, a moving shaft 3, and a torsion spring. The charging component 1 includes a detachably connected moving bracket 11 and a conductive sheet 12. The moving bracket 11 has a bend formed on it, and its overall structure is similar to an L-shape or a T-shape. The follower swing arm of the torsion spring is connected to the moving bracket 11.

[0059] Specifically, referring to Figure 3, the end of the follower arm of the torsion spring is bent to form a corner, and the movable bracket 11 is provided with a limiting through hole 1112 for mounting the follower arm. When the torsion spring is connected to the movable bracket 11, referring to Figure 1, the follower arm passes through the limiting through hole 1112, and the corner portion of the follower arm can be exposed relative to the limiting through hole 1112, so as to achieve a firm fixation between the follower arm and the limiting through hole 1112. The corner structure and the limiting through hole 1112 help to avoid the possibility of the torsion spring detaching from the movable bracket 11 under the force of elastic deformation.

[0060] In this embodiment or other similar embodiments, the movable support 11 can be an integral structure or a split structure.

[0061] Please refer to Figures 4-5. The movable bracket 11 includes a movable part 111 and an abutting part 112 connected together. One end of the movable part 111 facing away from the abutting part 112 is connected to the mounting base 210 through the movable shaft 3. The follower end 202 is provided on the movable part 111, and the conductive sheet 12 is provided on the abutting part 112.

[0062] Specifically, the movable part 111 is provided with a shaft hole 1111, and the movable shaft 3 passes through the shaft hole 1111; or, the movable part 111 is sleeved on the movable shaft 3 through the shaft hole 1111 for mounting on the mounting base 210. In addition, the aforementioned limiting through hole 1112 is also provided on the movable part 111, and the follower torsion arm 23 passes through the limiting through hole 1112 and is connected to the movable shaft 3.

[0063] Please refer to Figure 5. Although the moving part 111 and the abutting part 112 are connected by a bend structure and extend in different directions, they are basically perpendicular or approximately perpendicular.

[0064] The internal space of a cleaning base station is limited, requiring a reasonable arrangement of the positions and space occupancy of various components according to design requirements, while ensuring that these components do not interfere with each other. To achieve this, the size and space occupancy of the charging device 10 used to charge the cleaning host are also limited by the internal space layout of the cleaning base station, and the charging device 10 also affects the arrangement of other components. To reduce the space occupancy of the charging device 10 within the cleaning base station, and to achieve the compactness and miniaturization of the cleaning base station as much as possible, the structure of the charging device 10 needs further optimization to meet the design requirements of the cleaning base station.

[0065] Based on the above objectives, the charging device 10 provided in this embodiment can shorten the swing arm size to a suitable length as needed.

[0066] Since the aforementioned contact portion 112 is used to cooperate with the conductive sheet 12 and realize the charging function of the charging device 10, the size of the contact portion 112 remains basically unchanged. Furthermore, since the size of the swing arm of the charging component 1 is mainly affected by the length of the aforementioned moving portion 111, under this premise, in order to shorten the size of the swing arm, the size of the moving portion 111 can be adjusted within a certain range as needed.

[0067] Specifically, the shorter the length of the mobile unit 111, the smaller the swing arm of the charging device 10, and the smaller its overall size. Correspondingly, the charging device 10 occupies less space within the clean base station.

[0068] In some embodiments, the length ratio of the moving part 111 and the abutting part 112 can be set to a range of 0.8-1.2. This range can effectively reduce the space occupied by the charging device 10 installed on the clean base station without affecting the normal charging function of the charging device 10.

[0069] The conductive sheet 12 described above has an overall C-shaped or U-shaped structure, as shown in Figures 4-5.

[0070] Specifically, the conductive sheet 12 is disposed at the end of the abutment portion 112 away from the moving portion 111, and includes a first connecting portion 122, a contact portion 121 and a second connecting portion 123 connected in sequence. The contact portion 121 is located at the free end of the abutment portion 112, that is, the side of the abutment portion 112 facing away from the second position. The first connecting portion 122 and the second connecting portion 123 are respectively located on both sides of the contact portion 121 and connected to the opposite sides of the contact portion 121. At this time, the first connecting portion 122 and the second connecting portion 123 are arranged opposite to each other and a space is formed between them for the abutment portion 112 to be inserted.

[0071] In some embodiments, the contact portion 121, the first connecting portion 122, and the second connecting portion 123 are integral structures and are formed by bending to form the conductive sheet 12.

[0072] Please refer to Figure 5. Both the first connecting portion 122 and the second connecting portion 123 have a latch 124 at the end furthest from the contact portion 121. The surface of the abutment portion 112 has a recessed groove 114 that matches the latch 124. When the conductive sheet 12 is fitted onto the abutment portion 112, the latch 124 can elastically deform and insert into the groove 114, achieving a secure connection between the conductive sheet 12 and the abutment portion 112.

[0073] The aforementioned buckle 124 and slot 114 cooperate with each other to effectively improve the bonding strength between the conductive sheet 12 and the abutment portion 112, and reduce the possibility that the conductive sheet 12 may detach from the abutment portion 112 under external force.

[0074] When the cleaning host enters the receiving cavity 220 within the cleaning base station, as the cleaning host continues to move, the abutment portion 112, on which the conductive sheet 12 is mounted, comes into contact with the cleaning host and moves from the first position to the second position under the continuous thrust provided by the cleaning host. During this process, the abutment portion 112 moves under the pull of the moving portion 111. The torsion spring connected to the moving portion 111 provides a continuous pressure to the abutment portion 112 and the contact portion 121 located on the abutment portion 112 during the movement, ensuring that the contact portion 121 outside the abutment portion 112 maintains a tight abutment with the outer wall of the cleaning host. In other words, the contact portion 121, under the elastic force provided by the torsion spring, always moves with the cleaning host and abuts against the outer wall of the cleaning host, maintaining a stable contact.

[0075] Once the cleaning unit is in place, the contact part 112 moves to the second position and maintains stable contact with the cleaning unit. The cleaning unit achieves stable contact with the contact part 121 on the contact part 112 through a charging component (which may be a conductive contact or other conductive structure disclosed in related technologies), thus establishing circuit continuity. At this time, the cleaning base station, in its powered state, can supply power to the cleaning unit.

[0076] The structure of the conductive sheet 12 described above will be explained in detail below:

[0077] Referring to Figure 5, the conductive sheet 12 can be connected to the cleaning host via the contact portion 121. Therefore, the contact portion 121 is provided with a charging contact 1211, and the number of charging contacts 1211 is at least one, with any one charging contact 1211 protruding relative to the surface of the contact portion 121 and forming a contact surface 1212.

[0078] Please refer to Figures 1 and 5. The charging contact 1211 is a strip structure, and the extending direction of the charging contact 1211 is basically consistent with the axial direction of the moving shaft 3.

[0079] Specifically, the contact portion 121 is provided with two charging contacts 1211.

[0080] The surface of the charging contact 1211 can be a smooth curved surface. In some embodiments, a portion of the surface of the contact point can also be set to be a plane; for example, the contact surface 1212 can be set to be a plane.

[0081] Please refer to Figure 5. It can be seen that the contact surface 1212 is inclined relative to the surface of the contact portion 121.

[0082] Considering that the cleaning host located in the accommodating cavity 220 of the cleaning base station is tilted relative to the ground, the contact surface 1212 for electrical connection with the cleaning host is designed as an inclined surface. This allows for a larger contact area between the charging contact 1211 and the conductive component of the cleaning host, resulting in a tighter and more secure contact and reducing the probability of poor contact. Furthermore, since the actual position and tilt angle of the cleaning host may deviate slightly each time it enters the accommodating cavity 220, the inclined design of the charging contact 1211 better accommodates this imprecise connection. It allows for a certain degree of angular and positional deviation between the cleaning host and the charging device 10 within a certain range, ensuring a high success rate of electrical connection between the cleaning host and the charging device 10.

[0083] Since the position and angle at which the cleaning host enters the cleaning base station may vary slightly each time, affecting the alignment success rate of the cleaning host and the charging device 10, in order to solve this problem and reduce the probability of malfunctions caused by misalignment of the cleaning host, in some embodiments, at least two of the above-mentioned charging devices 10 may be provided in the cleaning base station, and the charging devices 10 may be arranged symmetrically about the same size relative to the accommodating cavity 220 in the cleaning base station.

[0084] The symmetrically arranged charging device 10 can guide the cleaning host as it enters the receiving cavity 220, and can also ensure the stability and efficiency of charging to a certain extent.

[0085] Since the charging contacts 1211 are inclined relative to the surface of the contact portion 121, when there are two charging devices 10 arranged symmetrically from left to right, the conductive sheet 12, which is detachably connected to the movable bracket 11, also has two different symmetrical arrangements. When assembling the charging device 10, the conductive sheet 12 and the movable bracket 11 need to be assembled one-to-one according to the different installation positions to avoid the charging contacts 1211 being installed backwards.

[0086] To further reduce the assembly difficulty of the charging contact 1211, in some embodiments, a foolproof design can be added to the charging component 1.

[0087] In some embodiments, the above-mentioned foolproof design includes a positioning protrusion 1231 and a slot 113 that cooperate with each other, wherein the positioning protrusion 1231 is provided on the second connecting portion 123, and the slot 113 is provided at the connection between the abutting portion 112 and the moving portion 111.

[0088] Specifically, taking the orientation shown in Figures 2 and 5 as an example, the second connecting portion 123 has a bottom wall 1232 near the mounting base 210 and a top wall 1233 away from the mounting base 210. The positioning protrusion 1231 is located on the side of the second connecting portion 123 away from the contact portion 121 and is offset from the center of the second connecting portion 123 in the height direction. The size of the slot 113 matches the size of the positioning protrusion 1231.

[0089] Specifically, the minimum distance between the positioning protrusion 1231 and the bottom wall 1232 is the first distance, and the minimum distance between the positioning protrusion 1231 and the top wall 1233 is the second distance. The first distance and the second distance are different in size. Since the size of the slot 113 matches the size of the positioning protrusion 1231, the conductive piece 12 can only be inserted when installed in the correct orientation. If the conductive piece 12 is installed incorrectly, the slot 113 cannot match the conductive piece 12 with the positioning protrusion 1231, which will prevent the installation from being completed.

[0090] Please refer to Figure 5. The distance between the positioning protrusion 1231 and the bottom wall 1232 is significantly smaller than the distance between the positioning protrusion 1231 and the top wall 1233. Accordingly, the slot 113 used to mate with the positioning protrusion 1231 can be a T-shaped structure.

[0091] Specifically, the aforementioned slot 113 is connected to the card slot 114.

[0092] In addition to implementing foolproof design through structural features, the correct installation position or method can also be indicated by marking text or directional information on the charging pad. For example, left and right can be marked directly on the charging pad; or different colored markings can be applied to the charging pad for guidance.

[0093] Please refer to Figures 1 and 4 for the structure after the charging plate and the mobile bracket 11 are assembled.

[0094] To facilitate power supply to the charging chip, in some embodiments, a power supply component 1221 may be provided on the first connecting portion 122. Referring to Figures 4 and 5, in this case, the length of the first connecting portion 122 is greater than the length of the second connecting portion 123, and the power supply component 1221 may be provided on the portion of the first connecting portion 122 that extends relative to the movable bracket 11.

[0095] Specifically, the power supply component 1221 can be a hole-like structure, and the wire harness with power supply function is provided with conductive metal protrusions that match the power supply component 1221. After the wire harness is inserted into the hole-like power supply component 1221, it can be fixedly connected to the first connection part 122 and the circuit can be connected through the metal protrusions.

[0096] Furthermore, since the length of the first connecting part 122 is greater than the length of the second connecting part 123, a mark for indicating the installation position can be provided on the outer wall of the first connecting part 122 so that installers can quickly identify the correct assembly parts and perform the corresponding installation.

[0097] In other embodiments, in order to avoid the first connecting portion 122 affecting the normal movement of the charging device 10 between the first position and the second position, in some embodiments, the first connecting portion 122 may be bent after being installed on the movable bracket 11.

[0098] It is understood that the charging device 10 provided in this embodiment can effectively improve the flexibility of its size and specification adjustment while satisfying its basic charging function, making it more flexible in size range compared to conventional charging devices 10. When installation space is limited, the charging device 10 can achieve overall miniaturization without changing the size of the part of the charging device 10 used to contact the cleaning host, reducing the difficulty of miniaturizing the charging device 10 and achieving the effect of reducing the space occupation of the charging device 10 on the cleaning base station.

[0099] Figure 6 is a partial structural schematic diagram of the mounting base 210 in the clean base station provided in the embodiment of the present disclosure. Figure 7 is a structural schematic diagram of the charging device 10 in the clean base station provided in the embodiment of the present disclosure when it is located in the first position. Figure 8 is a structural schematic diagram of the charging device 10 in the clean base station provided in the embodiment of the present disclosure when it is located in the second position.

[0100] Please refer to Figures 6-8. This embodiment of the present disclosure also provides a cleaning base station, which is at least used for charging a cleaning host. The cleaning base station includes a charging device 10 and a base station body 20. The charging device 10 is any of the charging devices described above. The base station body 20 has a mounting base 210 and a receiving cavity 220 for accommodating the cleaning host.

[0101] In this clean base station, the specific structure of the charging device 10 can be the same as that of any embodiment of the charging device 10 described above, and will not be repeated here.

[0102] When the cleaning unit enters the receiving cavity 220 and applies a pushing force to the charging device 10, the charging device 10 can move to a second position relative to the receiving cavity 220. When the charging device 10 moves to the second position, the charging device 10 can be electrically connected to the charging component of the cleaning unit to charge the cleaning unit.

[0103] Specifically, the mounting base 210 is provided with a first mounting hole 211 and a second mounting hole 212 arranged at intervals. Please refer to Figure 6. The second mounting hole 212 is located on the side of the first mounting hole 211 away from the receiving cavity 220.

[0104] The movable shaft 3 is mounted on the mounting base 210 through the first mounting hole 211, and the movable bracket 11 is sleeved on the movable shaft 3; the fixed end 201 of the torsion spring, i.e. the fixed torsion arm 22, is mounted on the mounting base 210 through the second mounting hole 212, and the spring body 21 of the torsion spring is sleeved on the movable shaft 3.

[0105] Please refer to Figures 7-8. The mounting base 210 is also provided with a limiting wall 230. A first limiting block 231 protrudes from the limiting wall 230, and a second limiting block 13 is provided on the side of the charging component 1 facing the limiting wall 230.

[0106] When the charging component 1 is in the first position, please refer to Figure 7. At this time, the movable bracket 11 and the limiting wall 230 maintain a certain distance. When the charging component 1 moves to the second position, please refer to Figure 8. The second limiting block 13 moves closer to the limiting wall 230 and is in contact with the first limiting block 231 provided on the limiting wall 230.

[0107] A portion of the surface of the mounting base 210 protrudes to form a limiting wall 230. The limiting wall 230 protrudes towards the side of the moving path of the charging component 1 to form a first limiting block 231. Depending on the installation position of the charging device 10, the shapes of the limiting walls 230 formed on the left and right sides may be the same or different.

[0108] Please refer to Figures 2, 7, and 8. Within this clean base station, the aforementioned charging devices 10 are respectively located on the left and right sides of the accommodating cavity 220. The charging devices 10 shown in Figures 7 and 8 are located on the same side (right side in the figures). The charging device 10 shown in Figure 2 is located on the left side of the accommodating cavity 220, unlike the charging devices 10 shown in Figures 7 and 8. Correspondingly, the shape of the limiting wall 230 in Figure 2 is different from the shape of the limiting wall 230 in Figure 7.

[0109] Please refer to Figures 7-8. The accommodating cavity 220 is located above the mounting base 210. When the cleaning host leaves the accommodating cavity 220, the charging device 10 is in the first position. At this time, a large portion of the contact part 112 moves from above the mounting base 210 into the accommodating cavity 220. After the cleaning host enters the accommodating cavity 220 of the cleaning base station, as the cleaning host moves, the contact part 112 can maintain a close contact with the cleaning host in a straight line as it moves from the first position to the second position under the continuous thrust provided by the cleaning host, until the contact part 112 moves to the second position, at which time only a small portion of the contact part 112 is located in the accommodating cavity 220.

[0110] In this embodiment or other similar embodiments, in addition to charging the cleaning host, the cleaning base station can also be used to perform maintenance functions such as dust collection, cleaning, and water replenishment for the cleaning host, which will not be described in detail here.

[0111] It is understood that the cleaning base station provided in this embodiment has the above-mentioned charging device 10. Therefore, the beneficial effects of the cleaning base station including at least one or more of the above-mentioned charging devices 10 will not be elaborated here. On the other hand, the internal structure of the cleaning base station with the charging device 10 can be improved to a certain extent, becoming more compact and simple. At the same time, the reduced size of the charging device 10 can make more room for other functional modules (such as dust collection modules, cleaning modules, etc.), so as to integrate more and better different functions on the cleaning base station, making the functions of the base station richer and more complete. In addition, the charging device 10 can reduce the difficulty of miniaturizing the base station, reduce the installation space requirements of the cleaning base station, and improve the space utilization rate of the cleaning base station.

[0112] This disclosure also provides a cleaning system, including the cleaning base station and the cleaning host described above. The specific structure of the cleaning base station can be the same as that of any embodiment of the cleaning base station described above, and will not be repeated here.

[0113] The cleaning unit located in the accommodating cavity 220 can be charged by the charging device 10 located in the cleaning base station.

[0114] The cleaning system provided in this embodiment includes the aforementioned cleaning base station. Therefore, the cleaning system incorporates at least one or more of the beneficial effects of the aforementioned cleaning base stations, which will not be elaborated further here. Simultaneously, the cleaning system with the aforementioned charging device 10 can improve its internal space utilization, making its internal components more compact, and also contributes to the miniaturization of the cleaning base station and the cleaning system itself. When the size of the cleaning system is reduced, it helps to reduce the space occupied by the cleaning system during installation. This reduces the space requirements of the cleaning system, allowing it to be used in more compact installation spaces and reducing the difficulty of installation. Furthermore, the miniaturized cleaning system not only improves aesthetics and frees up more usable space for users during actual use, but also reduces its production and transportation costs to a certain extent.

[0115] Compared to the prior art, this disclosure includes at least the following beneficial effects:

[0116] The charging device provided in this disclosure includes a charging component and an elastic element. The charging component can move between a first position and a second position under the drive of the elastic element and an external force. Since the elastic element includes a fixed end and a follower end, and the follower end can move closer to the fixed end when the charging component moves towards the second position, it is possible to improve the form of the charging device while ensuring that it can be firmly connected to the corresponding cleaning host under elastic action. This makes it more flexible in size compared to conventional charging devices. When installation space is limited, the charging device can be miniaturized by directly shortening the moving arm of the charging component without changing the shape of the elastic element, effectively reducing the difficulty of miniaturizing the charging device. It also reduces the space occupation of the charging device within the cleaning base station. The cleaning base station and cleaning system provided in this disclosure include the above-mentioned charging device; therefore, the beneficial effects of the cleaning base station and cleaning system including at least one or more of the above-mentioned charging devices will not be elaborated further here. On the other hand, the cleaning base station and cleaning system with this charging device can improve their internal space utilization, making their internal controls more compact, and also contributing to the miniaturization improvement of the cleaning base station and cleaning system.

[0117] The description of the various embodiments above tends to emphasize the differences between the various embodiments. The similarities or similarities between them can be referred to, and for the sake of brevity, they will not be repeated here.

[0118] The above description is merely a preferred embodiment of this disclosure and is not intended to limit this disclosure. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
