[0051] As shown in Figures 1 to 8 The present application provides a water tank. The water tank comprises a water tank body and a fastening assembly. The water tank body comprises a tank body 10 and a tank cover 20, the tank cover 20 having a first position covering the tank body 10 and a second position separated from the tank body 10. The fastening assembly comprises a locking mechanism 30 and a fastening component 40, one of the locking mechanism 30 and the fastening component 40 is arranged on the tank body 10, and the other of the locking mechanism 30 and the fastening component 40 is arranged on the tank cover 20. The locking mechanism 30 has a locking position for fastening the tank cover 20 to the tank body 10 by fastening with the fastening component 40, and an unlocking position for unlocking the tank cover 20 from the tank body 10 by separating from the fastening component 40.

[0052] In the present application, the locking mechanism 30 and the fastening component 40 are fastened to lock the tank cover 20 on the tank body 10, and are separated to unlock the tank cover 20 from the tank body 10. After the locking mechanism 30 and the fastening component 40 are separated, the tank cover 20 can be detached from the tank body 10, and the user can more directly clean the inside of the tank body 10, the tank cover 20, and the connection between the tank body 10 and the tank cover 20, effectively reducing the health dead angle on the tank body 10 and the tank cover 20. At the same time, the user can also open or close the tank cover 20 according to actual needs, improving the user's use convenience. The fastening assembly is connected by the locking mechanism 30 in a fastening manner, making it more convenient for the user to disassemble and assemble the tank body 10 and the tank cover 20, and more convenient for the user to clean the water tank.

[0053] Furthermore, the fastening component 40 is disposed at one end of the housing 10 near the lid 20. An installation space 21 is provided within the lid 20. The locking mechanism 30 includes a driving component 31 and a locking component 32. The locking component 32 is installed within the installation space 21 and connected to the driving component 31. Driven by the driving component 31, the locking component 32 can extend at least partially out of the installation space 21 to fasten with the fastening component 40, or retract into the installation space 21 to separate from the fastening component 40. When the lid 20 covers the housing 10, the locking component 32 can fasten with the fastening component 40, locking the lid 20 securely onto the housing 10. By controlling the driving component 31, the locking component 32 can be driven to separate from the fastening component 40, unlocking the lid 20 from the housing 10. At this point, the user can remove the lid 20 from the housing 10 for cleaning operations. The locking component 32 is installed within the installation space 21. This design makes efficient use of the internal space of the tank cover 20, resulting in a more compact structure. The locking component 32 does not require additional external installation space 21, thus improving the aesthetics and neatness of the tank cover 20. Furthermore, the modular design of the locking component 32 and drive component 31 in the locking mechanism 30 facilitates assembly, disassembly, and maintenance of both components, reducing the production and maintenance costs of the water tank.

[0054] The fastening component 40 is provided with at least two engaging portions 421. The locking component 32 includes a first push plate 321 and a second push plate 322. Along the first direction (e.g. Figure 3 (In the direction indicated by the middle arrow X), the first push plate 321 is mounted on one side of the drive component 31. Along the first direction, the second push plate 322 is mounted on the other side of the drive component 31. The sides of the first push plate 321 and the second push plate 322 away from each other are respectively provided with locking portions 3211 corresponding to at least two engaging portions 421. The drive component 31 drives the first push plate 321 and the second push plate 322 closer together until the locking portions 3211 separate from the engaging portions 421, or away from each other until the locking portions 3211 engage with the engaging portions 421. The drive component 31 drives the first push plate 321 and the second push plate 322 closer together or away from each other, thereby controlling the engagement and disengagement of the locking portions 3211 and the engaging portions 421. Therefore, in this embodiment, by driving the first push plate 321 and the second push plate 322 away from each other through the drive component 31, the lid 20 is fastened to the body 10, making the connection between the lid 20 and the body 10 more stable and reliable. When it is necessary to remove the lid 20, the first push plate 321 and the second push plate 322 can be moved to a position close to each other by the drive component 31, making disassembly and assembly efficient and convenient. Multiple engaging parts 421 are engaged or disengaged from the locking parts 3211 in a one-to-one correspondence, which enhances the stability and reliability between the locking parts 3211 and the engaging parts 421, ensuring that the lid 20 and the box body 10 can be locked together more stably and reliably.

[0055] As shown in Figure 4 Fig. 3, the driving component 31 comprises a pushing block 311 and elastic members 312. The pushing block 311 is in sliding connection with the first pushing plate 321 and the second pushing plate 322 respectively through sliding connection structures and can move back and forth along the second direction (as indicated by the arrow Y in Fig. 3). The pushing block 311 pushes the first pushing plate 321 and the second pushing plate 322 to approach each other under the action of an external force. The elastic members 312 comprise at least two, at least one of which is connected between the first pushing plate 321 and the box cover 20 along the first direction, and at least another of which is connected between the second pushing plate 322 and the box cover 20. When the external force is removed, the pushing block 311 pushes the first pushing plate 321 and the second pushing plate 322 to move away from each other under the action of the elastic force of the elastic members 312. Figure 3

[0056] When the first pushing plate 321 and the second pushing plate 322 are located at the position of approaching each other, the elastic members 312 are in a compressed state, and when the external force applied to the pushing block 311 is removed, the elastic members 312 will elastically deform from the compressed state to a natural state, in the process, the elastic members 312 apply an elastic tension to the first pushing plate 321 and the second pushing plate 322, thereby pushing the first pushing plate 321 and the second pushing plate 322 to move away from each other to the position where the box cover 20 and the box body 10 are buckled. Such a driving structure not only has low assembly difficulty, but also does not need to increase an additional power source, thereby reducing the manufacturing cost of the water tank and the energy consumption required by the cleaning equipment. When unlocking the box cover 20 from the box body 10, the user only needs to apply an external force to the pushing block 311, and the locking part 3211 and the clamping part 421 can be easily separated, the operation process is simple and convenient, the operation difficulty of the user is reduced, and it is more labor-saving. When the external force is removed, the pushing block 311 can push the first pushing plate 321 and the second pushing plate 322 to move away from each other under the action of the elastic force of the elastic members 312, thereby realizing automatic reset and preparing for the next buckling of the locking part 3211 and the clamping part 421. Such a setting improves the convenience and efficiency of the user, and makes the user more smooth when opening and closing the box cover 20. In addition, the elastic members 312 not only provide elastic force, but also support and buffer the first pushing plate 321 and the second pushing plate 322 to a certain extent. During the buckling and separation of the locking part 3211 and the clamping part 421, the elastic members 312 can disperse part of the impact force between the locking part 3211 and the clamping part 421, reduce the wear between the locking part 3211 and the clamping part 421, and enhance the structural stability of the buckling assembly. The elastic members 312 can be compression springs, which are convenient to install and low in cost.

[0057] ​Further, along the second direction, one side of the outer wall surface of the box cover 20 is provided with an avoiding groove 22. The avoiding groove 22 is in communication with the mounting space 21. The pushing block 311 comprises a main body part 3111 and an extension segment 3112. The main body part 3111 is mounted in the mounting space 21, and a sliding connection structure is arranged between the main body part 3111 and the lock catch part 32. Along the second direction, the extension segment 3112 is located at the side of the main body part 3111 close to the avoiding groove 22 and at least partially located in the avoiding groove 22. The driving part 31 further comprises a pressing block 313. The pressing block 313 is connected in the avoiding groove 22 and can rotate to abut against the extension segment 3112. The pressing block 313 can rotate around an axis perpendicular to the second direction to abut against the extension segment 3112 and push the extension segment 3112 to drive the main body part 3111 to move along the second direction to make the first pushing plate 321 and the second pushing plate 322 close to each other. That is, the user applies an external force to the pressing block 313 to move the pressing block 313 along the second direction to drive the extension segment 3112 and the main body part 3111 to move along the second direction, so that the main body part 3111 moves and drives the first pushing plate 321 and the second pushing plate 322 to close to each other through the sliding connection structure, so that the box cover 20 can be taken off from the box body 10. At this time, the user can completely detach the box cover 20 from the box body 10 for cleaning operation, which ensures that the installation and disassembly operation between the box cover 20 and the box body 10 is relatively simple and convenient, and improves the user's experience. The main body part 3111 and part of the extension segment 3112 are located in the mounting space 21, which fully utilizes the structural space of the box cover 20, ensures that the pushing block 311 has enough installation and movement space, avoids the pushing block 311 occupying extra space outside the box cover 20, and makes the overall appearance of the water tank more simple and compact. Among them, the avoiding groove 22 not only facilitates the user to press the pressing block 313 to improve the convenience of unlocking, but also has a certain protection effect, which can protect the extension segment 3112 and the pressing block 313 from being accidentally touched to cause the box cover 20 to be accidentally opened. The pressing block 313 can be connected to the box cover 20 by hinging, the hinge between the pressing block 313 and the box cover 20 is staggered with the extension segment 3112, and the pressing block 313 rotates around the hinge to push the extension segment 3112 to move.

[0058] Among them, the extension segment 3112 is provided with an elastic rubber piece 31121, which is sleeved on the extension segment 3112 and is clamped with the inner wall surface of the mounting space. During the process of moving the pushing block 311 along the second direction by the user, the elastic rubber piece 31121 is extruded. After the user removes the external force, the elastic rubber piece 31121 rebounds and drives the pushing block 311 to reset.

[0059] Further, the pushing block 311 is located at the side of the locking component 32 away from the box body 10, and the sliding connection structure comprises a sliding column 3212 and a hole group structure. In the first direction, the first push plate 321 and the second push plate 322 are provided with the sliding column 3212 at the side close to each other, and the sliding column 3212 is located on the surface of the first push plate 321 and the second push plate 322 away from the box body 10. The hole group structure comprises a first strip hole 3113 and a second strip hole 3114 arranged adjacent to each other. The first strip hole 3113 is arranged at the side of the pushing block 311 close to the first push plate 321, and the sliding column 3212 on the first push plate 321 is at least partially arranged in the first strip hole 3113. The second strip hole 3114 is arranged at the side of the pushing block 311 close to the second push plate 322, and the sliding column 3212 on the second push plate 322 is at least partially arranged in the second strip hole 3114. In the first direction, the first strip hole 3113 and the second strip hole 3114 are inclined towards the side away from each other. The sliding column 3212 and the hole group structure in the sliding connection structure provide effective connection and movement guidance between the pushing block 311 and the first push plate 321 and the second push plate 322. When the pushing block 311 moves in the second direction, the force of the pushing block 311 is transmitted to the first push plate 321 and the second push plate 322 through the sliding of the sliding column 3212 in the inclined first strip hole 3113 and the second strip hole 3114, so that the first push plate 321 and the second push plate 322 can approach or move away from each other, realizing accurate clamping operation. The sliding connection structure ingeniously converts the linear motion of the pushing block 311 into the opposite or opposite motion of the first push plate 321 and the second push plate 322, ensuring the effective transmission of force and the accuracy of movement. In addition, when the pushing block 311 moves, the sliding column 3212 slides along the inner wall surface of the first strip hole 3113 and the second strip hole 3114, which can make the first push plate 321 and the second push plate 322 bear force more evenly, effectively prevent the first push plate 321 and the second push plate 322 from being jammed or locally stressed due to uneven force, improve the stability of the movement of the locking component 32, and further ensure the smoothness and reliability of the locking operation. The sliding connection structure adopts the cooperation of the sliding column 3212 and the hole group structure, and the sliding connection structure is simpler and easier to produce, which helps to reduce the production cost.

[0060] In some embodiments, the hole group structure can include at least two groups, and the at least two groups of hole group structures are arranged at intervals along the second direction. The at least two groups of hole group structures cooperate with the sliding column 3212 to convert the linear motion of the pushing block 311 into the opposite or opposite motion of the first pushing plate 321 and the second pushing plate 322, which can ensure that the pushing block 311 and the first pushing plate 321 and the second pushing plate 322 form multiple support points, can accurately guide the movement of the sliding column 3212, ensure that the main body part 3111 of the pushing block 311 and the locking part 32 cooperate more stably, and ensure that the user can more reliably perform the unlocking operation and the buckling operation between the locking part 32 and the buckling part 40.

[0061] Further, the box cover 20 includes a first housing 23 and a bottom cover 24. The bottom cover 24 is installed on the side of the first housing 23 close to the box body 10 and cooperates with the first housing 23 to form an installation space 21. The box cover 20 adopts a modular design, which is more convenient for installing the driving part 31 and the locking part 32 in the installation space 21 and facilitating the assembly operation of the box cover 20. This arrangement can also improve the assembly and disassembly and maintenance efficiency of the driving part 31 and the locking part 32.

[0062] Further, the box cover 20 is provided with a first recess 25 close to the side of the box body 10. The first recess 25 is arranged on the bottom cover 24. The first recess 25 is in communication with the installation space 21. When the first pushing plate 321 and the second pushing plate 322 are located away from each other, the locking part 3211 at least partially penetrates into the first recess 25. When the box cover 20 is located in the first position, the buckling part 40 at least partially penetrates into the first recess 25 to make the clamping part 421 buckled with the locking part 3211. The first recess 25 can provide a guiding effect for the buckling part 40, and the buckling part can more accurately penetrate into the first recess 25 to be buckled with the locking part 3211, thereby improving the stability and reliability of the connection between the box cover 20 and the box body 10. When the user installs the box cover 20 on the box body 10, aligns the first recess 25 of the box cover 20 with the clamping part 421 on the box body 10, and can accurately lock and install the box cover 20 on the box body 10, thereby providing an intuitive installation guide for the user and improving the user's experience.

[0063] Further, the first recesses 25 include at least two first recesses 25 which are arranged at intervals along the first direction. The buckling component 40 includes a mounting seat 41 and buckling flanges 42. The mounting seat 41 is connected to the side of the box body 10 close to the box cover 20, and the mounting seat 41 extends along the outer periphery of the box body 10 in a ring structure. The buckling flanges 42 are protruded on the side of the mounting seat 41 close to the box cover 20, and the buckling flanges 42 are matched with the first recesses 25.
