[0002] With the continuous development of cleaning technology, in order to completely free users' hands, cleaning equipment can also be entered into base stations for maintenance after completing its cleaning task. Base stations can output clean water to add to or use for cleaning the equipment. To improve the cleaning power of the water, base stations usually mix cleaning solution into the clean water before outputting it.

[0003] The cleaning fluid refill unit on the base station includes a cleaning fluid connector assembly and a detachable cleaning fluid cartridge. When the cleaning fluid in the cartridge is depleted, it can be removed from the base station, refilled, and then pushed back into the base station to connect with the cleaning fluid connector assembly. However, the connector on the existing cleaning fluid connector assembly is a fixed connector, making it difficult to align the cleaning fluid cartridge with the connector on the cleaning fluid connector assembly during installation. This high assembly difficulty severely impacts the user experience. Utility Model Content

[0046] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0047] The embodiments described in this application are merely some embodiments, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application. The term "comprising" as used throughout the specification and claims is an open-ended term and should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem and substantially achieve the technical effect within a certain error range. Furthermore, in the embodiments of this application, "multiple" refers to two or more. Those skilled in the art can combine and integrate different embodiments or examples described in this specification and the features of different embodiments or examples without contradiction. The descriptions such as "first" and "second" used herein are used to distinguish different directions, structures, components, etc., and do not represent a sequential order. Furthermore, the embodiments described below are merely some embodiments, not all embodiments.

[0048] After completing a cleaning task, a cleaning robot returns to its base station for maintenance. The base station can add cleaning water to the cleaning robot, clean the cleaning actuators on the robot, or output cleaning water to clean the base station itself.

[0049] To improve the cleaning effect of the clean water, the clean water output unit on the base station adds cleaning liquid, such as detergent, disinfectant, or multi-purpose detergent, to the clean water before outputting it.

[0050] To facilitate the addition of cleaning fluid by users, the cleaning fluid is typically added to a cleaning fluid cartridge, which is detachably connected to the base station. In addition to the cleaning fluid cartridge, the cleaning fluid refill unit on the base station also includes a cleaning fluid connector assembly. The cleaning fluid cartridge is detachably connected to the cleaning fluid connector assembly, allowing for easy extraction of cleaning fluid from the cartridge. When the cleaning fluid in the cartridge is depleted, the user can remove the cleaning fluid cartridge from the base station, add cleaning fluid, and then reinsert the cartridge into the base station, connecting it to the cleaning fluid connector assembly.

[0051] However, during the installation of the cleaning solution cartridge, manufacturing tolerances make it difficult to install it correctly. The cleaning solution connector assembly is often hard to connect precisely to the cartridge, leading not only to the inability to draw cleaning solution but also to leakage due to a loose connection. Furthermore, the user experience is poor, making it difficult to accurately determine if the cartridge is properly installed, severely impacting the user experience.

[0052] To solve the above technical problems, see Figure 1 and Figure 2 In one embodiment of this application, a cleaning fluid filling unit is provided, comprising: a cleaning fluid container 2 and a cleaning fluid connector assembly 1, wherein the cleaning fluid container 2 and the cleaning fluid connector assembly 1 are detachably connected. The cleaning fluid container 2 is provided with at least one infusion port 21. When the cleaning fluid container 2 is connected to the cleaning fluid connector assembly 1, the cleaning fluid connector assembly 1 is connected to the infusion port 21, thereby facilitating the extraction of cleaning fluid from the cleaning fluid container 2.

[0053] The cleaning fluid connector assembly 1 can be adapted to be connected to a base station. The cleaning fluid connector assembly 1 is connected to other components on the base station through a pipe to output the cleaning fluid in the cleaning fluid box 2 to the other components. For example, the cleaning fluid connector assembly 1 is connected to the clean water tank on the base station through a pipe, and the cleaning fluid connector assembly 1 can output the cleaning fluid in the cleaning fluid box 2 to the clean water tank to prepare cleaning water with better cleaning effect.

[0054] In one embodiment provided in this application, the cleaning fluid connector assembly 1 includes: a bracket 3, a connector assembly 4, and a connecting portion 5.

[0055] At least one connector assembly 4 is connected to the bracket 3, and a connecting part 5 is located on one side of the bracket 3. When the cleaning fluid connector assembly 1 is connected to the cleaning fluid container 2, the connector assembly 4 engages with the infusion port 21 on the cleaning fluid container 2. The connector assembly 4 has a solution channel 413, through which the cleaning fluid connector assembly 1 can draw cleaning fluid from the cleaning fluid container 2. The connecting part 5 engages with the body of the cleaning fluid container 2 to more stably connect the cleaning fluid container 2 and the cleaning fluid connector assembly 1, preventing the cleaning fluid container 2 from detaching from the cleaning fluid connector assembly 1 in case of an accident.

[0056] The connector assembly 4 has an axis K along its length, which can be considered as the direction in which the connector assembly 4 protrudes relative to the support 3. The connector assembly 4 can move back and forth relative to the support 3 along the axis K, and the connector assembly 4 can tilt and swing relative to the axis K.

[0057] When the user connects the cleaning fluid box 2 to the cleaning fluid connector assembly 1, due to manufacturing tolerances or other factors, the connector assembly 4 may be misaligned with the infusion port 21 of the cleaning fluid box 2. In this case, it will be difficult to assemble the cleaning fluid box 2 into the cleaning fluid connector assembly 1.

[0058] In the technical solution of this application, the connector assembly 4 is floatingly mounted on the bracket 3. The connector assembly 4 has multiple degrees of freedom relative to the bracket 3, and can move and swing axially and radially relative to the bracket 3 along axis K. When installing the cleaning fluid box 2, if there is a slight misalignment between the connector assembly 4 and the infusion port 21 of the cleaning fluid box 2, the connector assembly 4 can still be aligned with the infusion port 21 through its floating displacement, and a tight connection can be achieved. This method has low assembly difficulty, the cleaning fluid box 2 is less prone to leakage, has a higher fault tolerance rate, is more convenient for users, and provides a better user experience.

[0059] See Figures 1 to 4 In one embodiment provided in this application, the connector assembly 4 includes a cylindrical connector 41, and the bracket 3 is provided with at least one mounting hole 31, wherein at least one cylindrical connector 41 is floatably connected to the mounting hole 31. Figure 3 As shown, the bracket 3 has two parallel and spaced mounting holes 31, and correspondingly, the bracket 3 has two cylindrical connectors 41.

[0060] A floating connection can be considered as a movable gap between the cylindrical joint 41 and the mounting hole 31 in at least one direction. When the cylindrical joint 41 is subjected to an external force, the cylindrical joint 41 can undergo a certain amount of displacement relative to the mounting hole 31.

[0061] The cylindrical connector 41 includes a first segment 411 and a second segment 412 connected to each other. The first segment 411 is located on one side of the mounting hole 31, and the second segment 412 extends across to the other side of the mounting hole 31 and then extends away from the bracket 3.

[0062] In one specific implementation, the first segment 411 and the second segment 412 are arranged in a straight line. The first segment 411 is located to the left of the mounting hole, and the second segment 412 extends through the mounting hole 31 to the right of the mounting hole 31, forming a protruding cylindrical joint 41 relative to the bracket 3. Alternatively, the first segment 411 can be arranged perpendicular to the second segment 412, with the second segment 412 still forming a protruding cylindrical joint 41 relative to the bracket 3.

[0063] In the technical solution of this application, the connector assembly 4 can be floated in the mounting hole 31. Its first segment 411 is located on the left side of the mounting hole 31, and its second segment 412 is located on the right side of the mounting hole 31. This not only facilitates the floating of the connector assembly 4 relative to the bracket 3, but also makes it difficult for the connector assembly 4 to detach from the mounting hole 31.

[0064] Further, see Figure 2 The diameter of the second segment 412, which crosses the mounting hole 31, is less than or equal to the diameter of the mounting hole 31. The gap between the outer wall of the second segment 412 and the mounting hole 31 is M, and the value of M ranges from 0 mm to 5 mm. In a specific embodiment, the gap between the outer wall of the second segment 412 and the mounting hole 31 is 0.48 mm.

[0065] By making the diameter of the mounting hole 31 larger than the diameter of the second section 412, a movable clearance is provided for the connector assembly 4, which can also tilt and swing relative to the axis K, thereby achieving a floating connection effect.

[0066] To enable the connector assembly 4 to extract cleaning fluid from the cleaning fluid container 2, the first section 411 and the second section 412 are provided with interconnected solution channels 413, and the end of the second section 412 is provided with a solution hole that communicates with the solution channel 413. When the cylindrical connector 41 is inserted into the infusion port 21 of the cleaning fluid container 2, the cleaning fluid in the cleaning fluid container 2 can be extracted through the solution channel 413.

[0067] To facilitate the connection of the first segment 411 of the connector assembly 4 to the pipes inside the base station, the diameter of the solution channel 413 in the first segment 411 is smaller than the diameter of the solution channel 413 in the second segment 412. In addition, the end of the first segment 411 may have multiple output terminals, and different output terminals can be connected to different pipes inside the base station, thereby enabling the cleaning fluid filling unit to simultaneously supply cleaning fluid to multiple different components inside the base station.

[0068] As mentioned above, the connector assembly 4 is floatingly connected to the bracket 3. To prevent the connector assembly 4 from detaching from the bracket 3 and to allow the connector assembly 4 to return to its initial position, in one embodiment provided in this application, the connector assembly 4 further includes a limiting ring 42 and an elastic member 43. The limiting ring 42 is sleeved on the first segment 411 and abuts against the inner wall of the bracket 3. The elastic member 43 is sleeved on the second segment 412 and abuts against the outer wall of the bracket 3.

[0069] The diameter of the limiting ring 42 is larger than the diameter of the first segment 411, and the limiting ring 42 can effectively prevent the first segment 411 of the connector assembly 4 from moving to the right side of the bracket 3. The elastic element 43 is located on the right side of the bracket 3. When the connector assembly 4 is subjected to an external force in the direction of axis K, the elastic element 43 can act as a buffer. When the connector assembly 4 is subjected to a force that swings to one side relative to the direction of axis K, one side of the elastic element 43 is compressed. When the external force is removed, the elastic element 43 can drive the connector assembly 4 to return to the position of axis K.

[0070] The elastic element 43 includes, but is not limited to, springs, rubber rings, elastic plastic rings, etc.

[0071] Furthermore, in conjunction with see Figure 3 and Figure 4 To prevent the elastic element 43 from moving arbitrarily, in one embodiment provided in this application, the bracket 3 is provided with a mounting portion 32, which is located on the outer periphery of the mounting hole 31, and the first end of the elastic element 43 is connected to the mounting portion 32. Specifically, the mounting portion 32 is a recessed annular structure, located on the outer wall surface of the bracket 3, and is concentrically arranged with the mounting hole 31. The mounting portion 32 not only accommodates the elastic element 43, but its inner ring diameter is equal to the outer diameter of the elastic element 43, and one end of the elastic element 43 can be snapped into the mounting portion 32, thereby providing an auxiliary fixing effect for the elastic element 43.

[0072] In the technical solution provided in this application, the connector assembly 4 swings in a 360° direction within the gap M under the action of the installation force by compressing the elastic element 43. At the same time, the limiting ring 42 can limit the excessive swinging of the connector assembly 4 along the axial and radial directions of the axis K, which effectively improves the docking accuracy between the connector assembly 4 and the infusion hole 21 of the cleaning liquid box 2.

[0073] When cleaning fluid is needed, the connector assembly 4 inserts a portion of the cylindrical connector 41 into the infusion port 21 of the cleaning fluid box 2 to extract the cleaning fluid from the cleaning fluid box 2. However, if the cylindrical connector 41 is not precisely aligned with the infusion port 21, there is still a possibility of leakage at the connection point.

[0074] See Figure 2In one embodiment provided in this application, a sealing ring 414 is provided on the second segment 412. When the cylindrical connector 41 is partially inserted into the infusion hole 21 on the cleaning fluid box 2, the sealing ring 414 is connected to the infusion hole 21. The sealing ring 414 can effectively fill the gap between the second segment 412 of the cylindrical connector 41 and the infusion hole 21, thereby preventing the cleaning fluid in the cleaning fluid box 2 from leaking out of the gap.

[0075] Furthermore, to achieve a better sealing effect, the sealing ring 414 includes multiple elastic sealing rings with progressively decreasing diameters. When the second section 412 of the cylindrical connector 41 is connected to the infusion port 21, at least one sealing ring 414 is sealed in the infusion port 21. By setting elastic sealing rings 414 of different diameters, the sealing effect of the sealing ring 414 can be improved, and the sealing ring can also be adapted to infusion ports 21 of different sizes.

[0076] Because the force connecting the cleaning fluid connector assembly 1 and the cleaning fluid box 2 is relatively small, it is difficult for users to judge by feel whether the cleaning fluid box 2 is installed properly when installing it.

[0077] To improve the ease of installation of the cleaning fluid container 2, in one embodiment provided in this application, the connecting part 5 is disposed on the outer wall of the bracket 3. The connecting part 5 includes a connecting arm 51 and a buckle 52. The connecting arm 51 extends away from the bracket 3, and the buckle 52 is disposed at the end of the connecting arm 51. When the cleaning fluid connector assembly 1 is connected to the cleaning fluid container 2, the buckle 52 is engaged in the groove 22 on the outer wall of the cleaning fluid container 2.

[0078] When installing the cleaning solution container 2, the latch 52 first contacts the wall of the cleaning solution container 2. As the cleaning solution container 2 is pushed in, the latch 52 will generate a frictional resistance against the cleaning solution container 2. When the cleaning solution container 2 is pushed into the correct position, the latch 52 will engage with the groove 22 on the outer wall of the cleaning solution container 2.

[0079] Normally, the connecting arm 51 has a certain degree of elasticity. When the buckle 52 slides into the groove 22 on the outer wall of the cleaning liquid box 2, the buckle 52 hits the groove 22 and makes a "click" sound. This indicates that the cleaning liquid box 2 and the connecting connector assembly 4 are precisely connected, which can give the user an effective prompt.

[0080] In a specific example, see Figure 4 The buckle 52 is semi-circular, and the groove 22 on the outer wall of the cleaning fluid container 2 is a semi-circular slot. The connecting part 5 extends for a length L, which ranges from 10mm to 50mm. In one specific embodiment, the length of L is 34.9mm. By setting a connecting arm 51 of appropriate length, not only can a suitable elastic force be provided for the buckle 52, but the connecting part 5 can also guide the connection between the cleaning fluid container 2 and the cleaning fluid connector assembly 1.

[0081] By incorporating a connecting part 5 that matches the wall of the cleaning fluid container 2, the installation of the cleaning fluid container 2 can be achieved with a smooth feel. Furthermore, the floating connector assembly 4 allows the cleaning fluid container 2 to adapt to different positions, further enhancing the user's assembly experience.

[0082] See Figure 5 and Figure 6 In one embodiment of this application, a base station is also provided, comprising: a main body 6 and a cleaning fluid connector assembly 1. The main body 6 has at least one mounting cavity 61 for accommodating a cleaning fluid cartridge 2, and at least one cleaning fluid cartridge 2 can be fitted into the mounting cavity 61.

[0083] The cleaning fluid connector assembly 1 is located at the bottom of the mounting cavity 61, and the cleaning fluid box 2 is detachably connected to the mounting cavity 61. The cleaning fluid box 2 and the cleaning fluid connector assembly 1 are detachably connected.

[0084] See Figures 1 to 4 The cleaning fluid connector assembly 1 includes a bracket 3, a connector assembly 4, and a connecting part 5. The connector assembly 4 is connected to the bracket 3, and the connecting part 5 is located on one side of the bracket 3. When the cleaning fluid connector assembly 1 is connected to the cleaning fluid container 2, the connector assembly 4 engages with the infusion port 21 on the cleaning fluid container 2, and the connecting part 5 engages with the container body of the cleaning fluid container 2. The connector assembly 4 has an axis K along its length, allowing it to move back and forth relative to the bracket 3 along the axis K, and also allowing it to tilt and swing relative to the axis K.

[0085] The base station is also equipped with a pipe that connects to the cleaning fluid connector assembly 1. The pipe can draw cleaning fluid from the cleaning fluid box 2 through the cleaning fluid connector assembly 1. The cleaning robot can be connected to the base station. The base station can provide the cleaning robot with cleaning water mixed with cleaning fluid, and can also output cleaning water mixed with cleaning fluid to clean the cleaning actuators on the cleaning robot. It can also output cleaning water mixed with cleaning fluid to clean the cleaning tank on the base station.

[0086] For the specific structure of the cleaning fluid connector assembly 1, please refer to the description above; it will not be repeated here.

[0087] Application Scenario 1

[0088] When the cleaning fluid in the cleaning fluid cartridge on the base station is depleted, the user can pull the cartridge out of the base station to its maximum position, open the rubber stopper on the cleaning fluid refill port to refill it, and then push the cartridge back into the mounting cavity, connecting it to the cleaning fluid connector assembly. The base station can then continue to draw cleaning fluid from the cartridge. Because the connector assembly is floating relative to the support at the bottom of the mounting cavity, it has multiple degrees of freedom, allowing for a floating connection between the connector assembly and the cleaning fluid cartridge. This eliminates assembly difficulties caused by poor connection during manufacturing and assembly, while also preventing leakage and improving the user experience.

[0089] In summary, the connector assembly is floatingly mounted on the bracket, possessing multiple degrees of freedom relative to the bracket. During the installation of the cleaning fluid cartridge, even with slight misalignment between the connector assembly and the infusion port, the floating displacement of the connector assembly ensures it still aligns with the infusion port. This simplifies assembly, reduces leakage, provides a higher tolerance for errors, and enhances user convenience, resulting in a better user experience. Furthermore, the connector's design guides the cleaning fluid cartridge into the mounting cavity on the base station. When fully inserted, the latches on the connector engage with the grooves on the cleaning fluid cartridge, improving the user's assembly feel.

[0090] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
