[0044] 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.

[0045] 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.

[0046] Cleaning equipment typically has functions such as cleaning or disinfection. To achieve these functions, cleaning equipment usually needs to be equipped with corresponding functional fluids, such as cleaning solutions and disinfectants. For ease of maintenance, these functional fluids are usually contained in a fluid reservoir assembly, which is detachably connected to the cleaning equipment. When the functional fluid in the fluid reservoir assembly is used up, the user can open the lid of the fluid reservoir assembly to add more functional fluid.

[0047] To prevent leakage and evaporation of the functional fluid in the cartridge assembly, the cartridge assembly typically needs to have good sealing performance. Common leak-proof measures include installing elastic structures such as sealing rings at the connection between the cartridge body and the lid. However, these elastic structures are prone to aging after prolonged use, which will cause the cleaning fluid cartridge to lose its seal and leak easily.

[0048] To address the aforementioned technical issues as much as possible, see [link / reference]. Figures 1 to 5 In one embodiment of this application, a liquid container assembly is provided, comprising: a container body 1 and a container lid 2. The container body 1 has an open inner cavity 3, and a first connecting portion 11 is provided at the edge of the open cavity. The container lid 2 can be connected to the open cavity, and the container lid 2 is provided with a second connecting portion 21, which can cooperate with the first connecting portion 11 for connection.

[0049] The first connecting part 11 and / or the second connecting part 21 are provided with multiple annular sealing ribs 4. When the lid 2 is connected to the box body 1, the first connecting part 11 and the second connecting part 21 are press-fitted together by the sealing ribs 4. Specifically, the lid 2 can be fastened to the opening of the box body 1, thereby forming a sealed cavity 3 in the opening, in which the functional liquid can be stored. The connection between the lid 2 and the box body 1 is mainly achieved through the cooperation of the first connecting part 11 and the second connecting part 21.

[0050] In the technical solution provided in this application, the first connecting part 11 and / or the second connecting part 21 are provided with multiple annular sealing ribs 4. The sealing ribs 4 can be interference-fitted between the first connecting part 11 and the second connecting part 21, thereby sealing the gap between the first connecting part 11 and the second connecting part 21. The lid 2 can be tightly connected to the box body 1, with good sealing performance and no problem of aging and sealing failure. In addition, the sealing ribs 4 are used directly for sealing, eliminating the need for additional elastic sealing elements, which can save on the production cost of the liquid box assembly.

[0051] In the solution provided in this application, the sealing rib 4 can be disposed on the first connecting part 11, or on the second connecting part 21, or multiple annular sealing ribs 4 can be disposed on both the first connecting part 11 and the second connecting part 21. The following is a detailed description of the sealing rib 4 being disposed on the first connecting part 11.

[0052] See Figures 2 to 5 In one embodiment provided in this application, multiple annular sealing ribs 4 are spaced apart from each other, and grooves are formed between the sealing ribs 4. After the first connecting part 11 and the second connecting part 21 are connected, the gaps between the multiple sealing ribs 4 and the wall surface of the second connecting part 21 form a hollow cavity 5. Specifically, two adjacent sealing ribs 4 can be press-fitted to the wall surface of the second connecting part 21, and the hollow cavity 5 can form a structure similar to an air chamber, and the air chamber is independently sealed.

[0053] The multiple annular sealing ribs 4 not only form a multi-layered seal, further improving the stability of the seal, but the air chambers formed by the hollow cavities 5 between the sealing ribs 4 also provide an auxiliary sealing effect. For example, when the first sealing rib 4 fails, because there is gas in the air chamber and the gas pressure is in a balanced state, the functional fluid is not easily leaked into the air chamber, and therefore is less likely to leak outwards.

[0054] In the technical solution provided in this application, the sealing rib 4 may be made of the same or different material as the first connecting part 11 or the second connecting part 21. For example, the sealing rib 4 may be made of the same material as the liquid box assembly, and the sealing rib 4 may be integrally formed on the liquid box assembly. Alternatively, to obtain better wear resistance, the sealing rib 4 may be made of metal and may be bonded to the liquid box assembly by adhesive bonding.

[0055] See Figures 2 to 5In one embodiment provided in this application, the shape of the first connecting portion 11 matches the shape of the second connecting portion 21. For example, the first connecting portion 11 is a first annular protrusion structure perpendicular to the plane of the opening, and multiple annular sealing ribs 4 are provided on the outer wall surface of the first annular protrusion structure. The second connecting portion 21 is a second annular protrusion structure perpendicular to the lid 2, and the diameter of the inner wall of the second annular protrusion structure is greater than or equal to the diameter of the outer wall of the first annular protrusion structure.

[0056] It should be noted that, as Figure 3 As shown, wall surface A is the inner wall surface of the second annular protrusion structure, wall surface B is the outer wall surface of the second annular protrusion structure, wall surface C is the inner wall surface of the first annular protrusion, and wall surface D is the outer wall surface of the first annular protrusion.

[0057] This can be understood as follows: when the lid 2 is connected to the body 1, the second annular protrusion structure is sleeved on the outside of the first annular protrusion structure, the inner wall surface of the second annular protrusion structure is opposite to the outer wall surface of the first annular protrusion structure, and the sealing ring is interference-fitted between the two.

[0058] In another specific embodiment, the second connecting part 21 is an annular groove perpendicular to the lid 2, and the outer wall diameter of the annular groove is greater than or equal to the outer wall diameter of the first annular protrusion structure. When the first connecting part 11 is connected to the second connecting part 21, the first connecting part 11, as a protrusion end, can be inserted into the annular groove formed by the second connecting part 21, and the multiple annular sealing ribs 4 on the outer wall of the first connecting part 11 can be interference-fitted to the outer wall of the annular groove.

[0059] In the technical solution provided in this application, by making the first connecting part 11 and the second connecting part 21 cooperate and connect with each other, a better seal can be obtained after the box body 1 and the box cover 2 are connected. In addition, the first connecting part 11 and the second connecting part 21 can help guide the box cover 2 to dock with the box body 1, making it more convenient for users to use.

[0060] In the technical solution provided in this application, in addition to the second connecting part 21 being an annular groove, it can also be a structure formed by multiple second connecting parts 21 forming an annular groove. Specifically, the cover 2 is provided with two second connecting parts 21 spaced apart, and an annular groove is formed between the two second connecting parts 21.

[0061] The first connecting part 11 can be connected to the annular groove, and the inner wall of the first connecting part 11 (e.g.) Figure 3 Middle wall surface C) and outer wall surface (e.g.) Figure 3Multiple annular sealing ribs 4 are provided on the middle wall surface D). For example, when the first connecting part 11 and the second connecting part 21 are connected, the multiple annular sealing ribs 4 on the inner wall of the first connecting part 11 can be press-fitted to the side wall of one of the second connecting parts 21, and the multiple annular sealing ribs 4 on the outer wall of the first connecting part 11 can be press-fitted to the side wall of the other second connecting part 21. This technical solution can form multiple sealing protections on the inner and outer sides of the first connecting part 11.

[0062] As mentioned above, the first connecting part 11 and the second connecting part 21 are connected by an interference fit between the sealing rib 4 and the wall surface of the second connecting part 21. However, the sealing rib 4 is not securely connected to the wall surface and is prone to falling off.

[0063] See Figure 6 Therefore, in order to ensure that the lid 2 can be securely connected to the box body 1, the second connecting part 21 is provided with an annular groove 6. When the lid 2 is connected to the box body 1, the sealing rib 4 is engaged in the groove 6. Specifically, the second connecting part 21 has multiple annular grooves 6 at the positions corresponding to the sealing rib 4. When the lid 2 is fastened to the box body 1, the raised sealing rib 4 can be engaged in the grooves on the second connecting part 21.

[0064] In order to achieve an interference fit between the sealing rib 4 and the groove 6, the depth of the groove 6 is less than the height of the protrusion of the sealing rib 4, the shape of the protruding end of the sealing rib 4 matches the shape of the groove 6, and part of the sealing rib 4 can be connected in the groove 6.

[0065] Of course, the depth of the groove can also be equal to the height of the sealing rib 4 protrusion, and the two can also achieve a good sealing effect after being connected.

[0066] See Figure 5 In one embodiment provided in this application, when the first connecting portion 11 is connected to the second connecting portion 21, the outer wall of the second connecting portion 21 (e.g., Figure 3 The middle wall surface B) and the outer wall of the box 1 (e.g.) Figure 3 The middle wall surface E) is flush with it. Specifically, a notch is provided on one side of the first connecting part 11 at the opening of the box body 1. When the box cover 2 is connected to the box body 1, the second connecting part 21 will be connected to the notch, and the outer wall of the second connecting part 21 is flush with the outer wall of the box body 1.

[0067] Further, see Figure 1 and Figure 5In one embodiment provided in this application, the lid 2 is further provided with a protruding structure 7, which is located inside the second connecting portion 21. The protruding structure 7 is spaced apart from the second connecting portion 21, and the height of the protruding structure 7 is greater than the height of the second connecting portion 21. Since the size of the ring of the protruding structure 7 is smaller than the size of the opening of the box body 1, the protruding structure 7 is easier to connect to the box body 1, which can help the lid 2 to be fastened to the box body 1, making it convenient for the user to install the lid 2. In addition, the protruding structure 7 can also provide a certain shielding effect, preventing the functional liquid inside the box from directly impacting the connection between the box body 1 and the lid 2 when shaken, thus avoiding leakage.

[0068] Furthermore, for the user's convenience in opening and closing the lid, see [link / reference]. Figure 4 and Figure 5 In one embodiment provided in this application, at least one side of the lid 2 includes an outwardly extending extension 8, which extends upwardly relative to the body of the lid 2. When it is necessary to open the lid, the user can grasp the extension 8 and pry it outward to separate the sealing rib 4 from the second connecting part 21.

[0069] In another embodiment of this application, a cleaning device is provided, comprising: a device body and at least one cleaning liquid container. The liquid container assembly is detachably connected to the device body and is used to store a corresponding functional liquid. When the liquid container assembly is connected to the device body, a liquid dispensing component on the device body can be inserted into the liquid container assembly to facilitate the extraction of the functional liquid from the liquid container assembly.

[0070] join Figures 1 to 5 The liquid container assembly includes a container body 1 and a lid 2. The container body 1 has an open inner cavity 3, and a first connecting portion 11 is provided at the edge of the open cavity. The lid 2 can be connected to the open cavity, and the lid 2 has a second connecting portion 21, which can be connected to the first connecting portion 11. The first connecting portion 11 and / or the second connecting portion 21 are provided with multiple annular sealing ribs 4. When the lid 2 is connected to the container body 1, the first connecting portion 11 and the second connecting portion 21 are interference-fitted through the sealing ribs 4.

[0071] In the technical solutions provided in this application, the cleaning equipment includes, but is not limited to: cleaning robots, base stations for cleaning robots, floor scrubbers, vacuum cleaners, etc. The liquid container assembly can be a cleaning solvent container, a disinfectant container, a fragrance container, etc.

[0072] The liquid cartridge assembly is detachably connected to the device body. When the functional liquid in the liquid cartridge assembly is used up, the user can remove the liquid cartridge assembly from the device, open the lid 2 and add the corresponding functional liquid to the box body 1. After adding, close the lid 2 tightly and then reinstall the liquid cartridge assembly onto the device body to continue using the cleaning device.

[0073] The following is a brief introduction to the liquid cartridge component provided in this application through a specific application scenario.

[0074] Application scenarios

[0075] A base station for a cleaning robot allows the robot to travel to the base station for maintenance. For example, the base station can output a cleaning solution containing cleaning solvent to clean the cleaning actuators (such as rollers) on the cleaning robot. To enable the base station to output the cleaning solution containing cleaning solvent, it is equipped with a liquid tank assembly for storing the cleaning solvent. The base station can extract the cleaning solvent from the liquid tank assembly. When the cleaning solvent in the tank is used up, the user can remove the liquid tank assembly from the base station for refilling. To refill, the lid of the liquid tank assembly is opened, the cleaning solvent is added into the tank, and then the lid is closed. Because the first connecting part of the tank has multiple annular sealing ribs, which can be interference-fitted to the second connecting part, the liquid tank assembly has good sealing performance and is not prone to leakage.

[0076] In summary, the technical solution provided in this application provides a sealing rib at the connection between the lid and the body. When the lid is closed on the body, the sealing rib allows the first and second connecting parts to be interference-fitted, thereby making the lid tightly connected to the body to achieve better sealing. In addition, there is no need to set additional sealing components, which avoids water leakage due to aging of the sealing components and reduces production costs.

[0077] 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.
