[0017] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present disclosure.

[0018] In addition, the present disclosure may repeat reference numbers and / or reference letters in different examples. This repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or arrangements discussed. In addition, the present disclosure provides examples of various specific processes and materials, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0019] The technical solution of the present disclosure will be described below with reference to the accompanying drawings and specific embodiments.

[0020] FIG1 is a schematic diagram of the structure of a cleaning liquid tank lid in the related art. Referring to FIG1 , in the related art, the lid 100 of the cleaning liquid tank 1000 is provided with a cleaning liquid inlet 110 for adding cleaning liquid to the tank 1000. The cleaning liquid inlet 110 is provided with a lid 200 that is threadedly connected to the cleaning liquid inlet 110. To add cleaning liquid, the lid 200 needs to be rotated to remove it and expose the cleaning liquid inlet 110. This is not only inconvenient to rotate, but the lid 200 may also become unopenable due to corrosion, residual cleaning liquid, and other issues. Furthermore, since the lid 200 loses its connection with the lid 100 after removal, it is easily lost or rolled away. These problems with the cleaning liquid tank 1000 result in a poor user experience for customers.

[0021] FIG2 is a schematic structural diagram of a cleaning liquid tank cover according to some embodiments of the present disclosure; FIG3 is a cross-sectional view of the cleaning liquid tank cover in FIG2 . To address the above-mentioned problems existing in the cleaning liquid tank 1000, a cleaning liquid tank 1000 is provided according to some embodiments of the present disclosure. As shown in FIG2 and FIG3 , the cleaning liquid tank 1000 includes a body 1400 and a sealing cover 1200. The body 1400 is provided with a cleaning liquid cavity (the cleaning liquid cavity is provided inside the shell, not shown in the drawings) and a cleaning liquid filling port 1110 connected to the cleaning liquid cavity; the sealing cover 1200 is hinged to the body 1400. A sealing plug 1210 corresponding to the cleaning liquid filling port 1110 is provided on a side of the sealing cover 1200 adjacent to the body 1400, so that when the sealing cover 1200 is attached to the body 1400, the sealing plug 1210 is sealedly connected to the cleaning liquid filling port 1110. The sealing cover 1200 includes a hinged end 1220 and an open end 1230 opposite to the hinged end 1220 , and the sealing plug 1210 is located between the hinged end 1220 and the open end 1230 .

[0022] As shown in Figures 2 and 3, in the cleaning liquid tank 1000 of the present embodiment, the sealing cover 1200 is hingedly connected to the body 1400. When the sealing cover 1200 is opened, the opening end 1230 can be used to lift the sealing cover 1200, and the hinged end 1220 of the sealing cover 1200 can be rotated around the body 1400, thereby gradually moving the opening end 1230 and the sealing plug 1210 away from the body 1400, and separating the sealing plug 1210 from the cleaning liquid filling port 1110, allowing the cleaning liquid filling port 1110 to leak out, facilitating the addition of cleaning liquid. When the sealing cover 1200 is closed, the sealing cover 1200 can be pressed to rotate the hinged end 1220 of the sealing cover 1200 around the main body 1400, so that the opening end 1230 and the sealing plug 1210 gradually approach the main body 1400, and the sealing plug 1210 is sealed and connected to the cleaning liquid filling port 1110 to complete the sealing of the cleaning liquid filling port 1110.

[0023] In the cleaning liquid tank 1000 according to some embodiments of the present disclosure, the process of rotating the sealing cover 1200 is omitted when adding cleaning liquid, and a labor-saving lever structure is formed between the opening end 1230, the hinge 1221 end and the sealing plug 1210. A simple lifting operation can open the sealing cover 1200, making the opening of the sealing cover 1200 more labor-saving and convenient. In the cleaning liquid tank 1000 according to some embodiments of the present disclosure, a hinged connection is used instead of a threaded connection, which can, to a certain extent, avoid the defect that the sealing cover 1200 cannot be opened due to corrosion and other reasons. In addition, since the sealing cover 1200 and the body 1400 are hingedly connected, the sealing cover 1200 can remain connected to the body 1400 when in the open state, which can avoid the problem of the sealing cover 1200 being easily lost. In summary, the cleaning liquid tank 1000 can, to a certain extent, improve the user experience and increase user satisfaction.

[0024] Figure 4 illustrates the backflow prevention principle of the cleaning fluid tank cover in Figure 3 . In some embodiments, as shown in Figures 2 to 4 , a hinge 1221 can be provided at the hinged end 1220 of the sealing cover 1200. One end of the hinge 1221 is connected to the sealing cover 1200, and the other end of the hinge 1221 is connected to the body 1400, thereby hingedly connecting the sealing cover 1200 to the body 1400. In some embodiments, the cleaning fluid refill port 1110 is located at the top of the body 1400, thereby hingedly connecting the sealing cover 1200 to the top of the body 1400.

[0025] In some embodiments, as shown in FIG. 2 to FIG. 4 , the sealing cover 1200 may only cover the sealing plug 1210 and the cleaning fluid filling port 1110 area.

[0026] In some other embodiments, the sealing cover 1200 may also cover the entire top of the body 1400 , so that the top of the body 1400 in the cleaning liquid tank 1000 is entirely hidden under the sealing cover 1200 .

[0027] As an optional embodiment, as shown in Figures 2 to 4, the sealing plug 1210 may include a sealing body 1211 and a sealing ring 1212, wherein the sealing ring 1212 is sleeved on the sealing body 1211. When the sealing cover 1200 is attached to the body 1400, the sealing plug 1210 is inserted into the cleaning liquid filling port 1110 and the sealing ring 1212 is attached to the inner sidewall 1111 of the cleaning liquid filling port 1110.

[0028] In some embodiments, as shown in Figures 2 to 4 , in sealing plug 1210, a sealing body 1211 serves as the main structure of sealing plug 1210, and the structure of sealing body 1211 matches the structure of cleaning liquid filling port 1110. When cleaning liquid filling port 1110 is cylindrical, sealing body 1211 can also be cylindrical, with an outer diameter of sealing body 1211 being the same as or slightly smaller than the inner diameter of cleaning liquid filling port 1110, and a sealing ring 1212 can be sleeved on sealing body 1211. When the sealing cover 1200 is affixed to the main body 1400, the sealing plug 1210 is inserted into the cleaning liquid filling port 1110, and the sealing body 1211 supports the sealing ring 1212 so that the sealing ring 1212 is affixed to the inner wall 1111 of the cleaning liquid filling port 1110. Therefore, the sealing plug 1210 and the cleaning liquid filling port 1110 are sealed by the deformation of the sealing ring 1212 to achieve a sealed connection between the sealing plug 1210 and the cleaning liquid filling port 1110, that is, the cleaning liquid filling port 1110 of the cleaning liquid cavity is sealed by the sealing plug 1210.

[0029] In some embodiments, since the sealing ring 1212 in the sealing plug 1210 fits tightly with the inner wall 1111 of the cleaning liquid filling port 1110 to form a sealed connection, the inner wall 1111 of the cleaning liquid filling port 1110 will produce a certain movement resistance to the sealing plug 1210, which can prevent the sealing plug 1210 from falling out of the cleaning liquid filling port 1110 to a certain extent. That is to say, after the cleaning liquid tank 1000 is assembled in the cleaning base station, it can prevent the sealing plug 1210 from falling out of the cleaning liquid filling port 1110 due to the vibration of the cleaning base station, so as to ensure the sealing effect of the cleaning liquid filling port 1110 in the cleaning liquid tank 1000.

[0030] In some embodiments, as shown in Figures 2 to 4, a groove may be provided on the outer sidewall of the sealing body 1211. The groove is used to mount the sealing ring 1212, so that the sealing ring 1212 is fixed axially in the sealing body 1211, and prevents the sealing ring 1212 from moving relative to the sealing body 1211. When the sealing plug 1210 is inserted into the cleaning liquid filling port 1110, the groove can limit the movement of the sealing ring 1212 relative to the sealing body 1211, preventing the sealing ring 1212 from being unable to smoothly enter the cleaning liquid filling port 1110 due to resistance from the inner sidewall 1111 of the cleaning liquid filling port 1110. When the sealing plug 1210 is pulled out of the cleaning liquid filling port 1110, the groove can limit the movement of the sealing ring 1212 relative to the sealing body 1211, and prevent the sealing ring 1212 from being dislodged from the sealing body 1211 due to resistance from the inner sidewall 1111 of the cleaning liquid filling port 1110.

[0031] As an optional embodiment, as shown in FIG. 2 to FIG. 4 , the sealing cover 1200 is provided with a through vent hole 1240 at the sealing body 1211 .

[0032] In some embodiments, as shown in Figures 2 to 4, the sealing cover 1200 has a vent hole 1240 defined in the sealing body 1211. The vent hole 1240 extends through both sides of the sealing cover 1200, connecting the two sides of the sealing cover 1200. When the sealing cover 1200 is attached to the body 1400 and the sealing plug 1210 is inserted into the cleaning liquid filling port 1110, the vent hole 1240 allows the cleaning liquid chamber to communicate with the external environment, allowing air in the cleaning liquid chamber to be discharged, thereby preventing air pressure in the cleaning liquid chamber from hindering the insertion of the sealing plug 1210 into the cleaning liquid filling port 1110. After a portion of the cleaning liquid in the cleaning liquid chamber is used, some air can be released into the cleaning liquid chamber to prevent negative pressure from forming in the cleaning liquid chamber, which could prevent the cleaning liquid from being smoothly discharged from the cleaning liquid tank for use.

[0033] In some embodiments, as shown in Figures 2 to 4, the diameter of the vent hole 1240 can be determined based on the ventilation speed required by the cleaning liquid chamber. The diameter of the vent hole 1240 should not be too large to avoid affecting the sealing effect of the cleaning liquid filling port 1110. The diameter of the vent hole 1240 should also not be too small, because a too small diameter of the exhaust hole affects the ventilation speed, and a too small ventilation speed will affect the sealing operation of the sealing cap 1200 on the cleaning liquid filling port 1110 or affect the discharge and use of the cleaning liquid from the cleaning liquid chamber.

[0034] As an optional embodiment, as shown in FIG. 2 to FIG. 4 , the sealing body 1211 is a tubular sealing body 1211 , and the vent hole 1240 is located in the lumen of the tubular sealing body 1211 .

[0035] In some embodiments, as shown in Figures 2 to 4, the sealing body 1211 is a tubular sealing body 1211, which can reduce the weight of the sealing body 1211 and locate the vent hole 1240 in the lumen of the tubular sealing body 1211 without affecting the vent hole 1240 passing through both sides of the sealing cover 1200.

[0036] As an optional embodiment, as shown in FIG. 2 to FIG. 4 , a backflow prevention peripheral wall 1250 is provided around the periphery of the vent hole 1240 on one side of the sealing cover 1200 adjacent to the body 1400 .

[0037] In some embodiments, as shown in Figures 2 to 4, a backflow prevention wall 1250 is disposed around the periphery of the vent 1240. That is, a protruding structure may be provided on the side of the sealing cover 1200 adjacent to the body 1400, and a through hole may be provided in the protruding structure to communicate with the aforementioned vent 1240, so as to form an exhaust passage between the sealing cover 1200 and the body 1400. If the cleaning liquid tank 1000 or the cleaning base station equipped with the cleaning liquid tank 1000 is accidentally turned over or transported, the cleaning liquid tank 1000 may be inverted, and the cleaning liquid in the cleaning liquid chamber may easily overflow from the vent 1240. By providing the backflow prevention wall 1250 around the vent 1240, it is possible to prevent the cleaning liquid from flowing into the vent 1240 and overflowing from the vent 1240. As shown in Figure 4, the cleaning liquid flows back along the inner wall 1111 of the cleaning liquid filling port 1110, encounters the obstruction of the sealing ring 1212, and flows back into the tube cavity of the tubular sealing body 1211. When the cleaning liquid does not exceed the height of the anti-backflow wall 1250, the cleaning liquid can be prevented from flowing out of the vent 1240.

[0038] In some embodiments, as shown in Figures 2 to 4 , the height of the backflow prevention wall 1250 can be adjusted according to the design requirements of the cleaning liquid tank 1000. In one embodiment, the height of the backflow prevention wall 1250 is less than or equal to the height of the tubular sealing body 1211 to prevent the backflow prevention wall 1250 from being too high and interfering with the movement of the sealing plug 1210 relative to the cleaning liquid filling port 1110.

[0039] As an optional embodiment, as shown in Figures 2 to 4, the opening end 1230 is provided with a handle portion 1231 that is arched relative to the body 1400, or the body 1400 is provided with a handle groove that is recessed relative to the sealing cover 1200 at a position corresponding to the opening end 1230. The handle groove can be arched to facilitate the opening operation.

[0040] In some embodiments, as shown in Figures 2 to 4 , a handle portion 1231 is provided at the opening end 1230 of the sealing cover 1200, which is arched relative to the body 1400, to form a certain handle space between the opening end 1230 and the body 1400. When opening the sealing cover 1200, a finger can be inserted under the handle portion 1231, thereby conveniently removing the sealing cover 1200 from the body 1400.

[0041] In some other embodiments, a finger groove that is recessed relative to the sealing cover 1200 may be provided on the body 1400 at a position corresponding to the opening end 1230, thereby forming a certain finger space between the opening end 1230 and the body 1400. When opening the sealing cover 1200, a finger can be inserted into the finger groove so that the finger is located below the opening end 1230, thereby conveniently opening the sealing cover 1200 from the body 1400.

[0042] The latch portion 1231 and the latch groove occupy a small space and will not interfere with the rotation of the sealing cover 1200 relative to the body 1400 through the hinge 1221.

[0043] In other embodiments, a handle may be provided on the side of the opening end 1230 of the sealing cover 1200 away from the body 1400 , and the sealing cover 1200 may be opened by pulling the handle.

[0044] As an optional embodiment, as shown in FIG. 2 to FIG. 4 , the distance between the sealing plug 1210 and the hinged end 1220 is greater than the distance between the sealing plug 1210 and the open end 1230 .

[0045] In some embodiments, as shown in Figures 2 to 4, the distance between the sealing cover 1200 and the hinged end 1220 is greater than the distance between the sealing plug 1210 and the open end 1230, that is, the sealing plug 1210 is closer to the open end 1230. During the opening process of the sealing cover 1200, the sealing cover 1200 rotates around the body 1400 by a smaller angle via the hinge 1221, so that the sealing plug 1210 can be pulled out of the cleaning liquid filling port 1110, making the opening operation of the sealing cover 1200 simpler and more convenient. During the closing process of the sealing cover 1200, the formation of pressing the sealing cover 1200 is also relatively short. As an optional embodiment, as shown in Figures 2 to 4, the body 1400 is provided with a guide slope 1120 around the cleaning liquid filling port 1110.

[0046] In some embodiments, as shown in Figures 2 to 4, a guide slope 1120 may be provided around the cleaning liquid filling port 1110 on the body 1400. The guide slope 1120 can gradually raise the periphery of the cleaning liquid filling port 1110, and liquid around the cleaning liquid filling port 1110 can flow toward the cleaning liquid filling port 1110 under the action of the guide slope 1120 and gravity. In some embodiments, the cleaning liquid filling port 1110 has a small diameter. When filling cleaning liquid, if cleaning liquid is accidentally spilled around the cleaning liquid filling port 1110, the cleaning liquid can automatically flow into the cleaning liquid filling port 1110 under the action of the guide slope 1120. The spilled cleaning liquid will not be wasted, will not contaminate the cleaning liquid tank 1000, and there is no need to specially clean up the spilled cleaning liquid, thereby making the filling of the cleaning liquid more convenient and simple.

[0047] As an optional implementation, as shown in FIG. 2 to FIG. 4 , the sealing cover 1200 at least covers the guide slope 1120 .

[0048] In some embodiments, as shown in Figures 2 to 4, the sealing cover 1200 covers at least the guide slope 1120, which can make the appearance of the cleaning liquid tank 1000 smoother and more beautiful. By shielding the guide slope 1120 with the sealing cover 1200, dust and other pollutants will not accumulate on the guide slope 1120.

[0049] As an optional embodiment, as shown in Figures 2 to 4 , the body 1400 is an integrated structure. In some embodiments, the body 1400 may include a box body 1300 and a cover body 1100 covering the box body 1300 , and the sealing cover 1200 is hinged to the cover body 1100 .

[0050] In some embodiments, the body 1400 may be an integral structure. The body 1400 may be integrally formed by injection molding. The sealing cover 1200 is hingedly connected to the body 1400 via a hinge 1221 .

[0051] In some embodiments, as shown in Figures 2 to 4 , the body 1400 may include a box 1300 and a cover 1100 disposed on the box 1300. The box 1300 and the cover 1100 are separately manufactured and then assembled together using a snap-fit ​​connection or other connection method. The sealing cover 1200 is then hingedly connected to the body 1400 via a hinge 1221.

[0052] In some embodiments, the cleaning liquid tank 1000 can also be combined with a clean water tank, a sewage tank, etc. to form a liquid supply assembly. In this case, a sealing cover 1200 can be set separately for the cleaning liquid filling port 1110, or the sealing cover 1200 can cover the top of the entire liquid supply assembly.

[0053] According to some embodiments of the present disclosure, a cleaning base station is further proposed, which includes the above-mentioned cleaning liquid tank 1000.

[0054] Since the cleaning base station provided by the present disclosure includes the cleaning liquid tank 1000 of the above technical solution, the cleaning base station provided by the present disclosure has all the beneficial effects of the above cleaning liquid tank 1000, which will not be described in detail here.

[0055] In some embodiments, as shown in Figures 2 to 4, when the cleaning base station needs to be replenished with cleaning fluid, a finger is inserted into the handle portion 1231 of the opening end 1230 to open the sealing cover 1200, allowing the sealing plug 1210 to be removed from the cleaning fluid filling port 1110. The hinge 1221 ensures that the sealing cover 1200 and the main body are not separated, and cleaning fluid is poured into the cleaning fluid filling port 1110 as needed. When the cleaning fluid is poured, the sealing cover 1200 is closed and pressed to compress the sealing ring 1212, causing the sealing ring 1212 to elastically deform and seal against the inner side of the cleaning fluid filling port 1110. The vent hole 1240 releases pressure to ensure that the sealing cover 1200 can be pressed into place.

[0056] The technical solutions according to the embodiments of the present disclosure have at least the following beneficial effects: In the cleaning liquid tank described above, the sealing cover is hingedly connected to the body. When the sealing cover is opened, the opening end can be lifted up, causing the hinged end of the sealing cover to rotate about the body, thereby gradually moving the opening end and the sealing plug away from the body and disengaging the sealing plug from the cleaning liquid filling port, allowing the cleaning liquid filling port to leak out and facilitate filling. When the sealing cover is closed, the hinged end of the sealing cover can be pressed to rotate about the body, thereby gradually moving the opening end and the sealing plug toward the body and sealingly connecting the sealing plug to the cleaning liquid filling port, thereby sealing the cleaning liquid filling port. In the cleaning liquid tank according to some embodiments of the present disclosure, the process of rotating the sealing cover when adding cleaning liquid is eliminated. A labor-saving lever structure is formed between the opening end, the hinged end, and the sealing plug. The sealing cover can be opened with a simple lifting operation, making opening the sealing cover more labor-saving and convenient. Using a hinged connection instead of a threaded connection can, to a certain extent, avoid the disadvantage of the sealing cover being unable to be opened due to corrosion and other reasons. In addition, since the sealing cover is hingedly connected to the body, the sealing cover can remain connected to the body when opened, which can prevent the sealing cover from being easily lost. In summary, the cleaning liquid tank according to some embodiments of the present disclosure can improve user experience and increase user satisfaction to a certain extent.

[0057] It should be noted that all directional indications in the embodiments of the present disclosure are only used to explain the relative position relationship, movement status, etc. between various components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0058] In this disclosure, unless otherwise expressly specified or limited, the terms "connect," "fix," etc. should be understood in a broad sense. For example, "fix" can mean a fixed connection, a detachable connection, or an integral connection; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean internal communication between two elements or an interaction between two elements, unless otherwise expressly specified. Those skilled in the art will understand the specific meanings of the above terms in this disclosure based on specific circumstances.

[0059] Although the embodiments of the present disclosure have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and alterations may be made to the embodiments without departing from the principles and spirit of the present disclosure, the scope of which is defined by the claims and their equivalents.
