DETAILED DESCRIPTION

[0033] In order to explain the technical content, structural features, achieved objectives and effects of the technical solution in detail, the following is a detailed description in conjunction with specific embodiments and accompanying drawings.

[0034] See also Figure 1 and Fig.10 In this embodiment, a water tank installation and fixing assembly includes a water tank support 1 fixed on an intelligent cleaning device (not shown) for carrying a water tank 2, and a water tank 2 movably fixed in a mounting groove 11 of the water tank support 1. The water tank 2 can be stably positioned in the mounting groove 11 of the water tank support 1 and can be easily taken out from the mounting groove 11. The water tank 2 is used to store cleaning water. When the water tank 2 is installed on the water tank support 1, a channel for water pumping is formed between the two. The water in the water tank 2 is pumped out through the channel to achieve the cleaning function.

[0035] See also Figure 2 , Figure 3 , Figure 4 , Figure 2-4 The structure of the water tank support 1 in this embodiment is shown from different perspectives. A mounting groove 11 with a top opening and used to accommodate the water tank 2 is formed on the water tank support 1. The mounting groove 11 is roughly a rectangular groove body, and the bottom of the mounting groove 11 protrudes upward near the middle position to form a first protrusion 12. As an example, the first protrusion 12 is a circular protrusion structure, and a first magnetic block 13 is fixed to the top of the first protrusion 12. Figure 5 and Figure 7 The water tank 2 shown has a shape that is roughly the same as the structure of the mounting groove 11, that is, it is formed into a rectangular box body, the top cover of the water tank 2 is provided with a top cover 21, the bottom of the water tank 2 is convex upward and forms a second convex portion 28 corresponding to the first convex portion 12, the second convex portion 28 is also a circular structure, and a positioning groove 28a is formed at its bottom, and a second magnetic block 29 corresponding to the first magnetic block 13 is fixedly installed at the bottom of the positioning groove 28a. When the water tank 2 is placed in the mounting groove 11, the first convex portion 12 on the water tank support 1 is just inserted into the positioning groove 28a at the bottom of the water tank 2, and at the same time, the first magnetic block 13 and the second magnetic block 29 attract each other, so that the water tank 2 is firmly positioned in the mounting groove 11 of the water tank support 1.

[0036] See also Figure 2 and Figure 6 A Hall switch 14 is fixedly installed outside the mounting groove 11 of the water tank support 1. The Hall switch 14 is set in the middle position of the front outer wall of the mounting groove 11, and the switch magnet 23 corresponding to the Hall switch 14 is fixedly installed at the corresponding position of the front end of the water tank 2. When the water tank 2 is fixedly placed in the mounting groove 11 of the water tank support 1, the switch magnet 23 corresponds to the position of the Hall switch 14, so the switch magnet 23 enters the detection range of the Hall switch 14. When the Hall switch 14 detects the switch magnet 23, it sends a prompt signal to the outside to indicate that the water tank 2 has been installed in place.

[0037] In this embodiment, the front end side wall of the installation groove 11 is recessed inward to form a first recessed portion 15. The first recessed portion 15 has a peripheral side and a top surface. The outer side of the first recessed portion 15 forms a water pump installation groove 15a11. A water inlet 18 is fixedly installed on the top surface of the first recessed portion 15. The water pump installation groove 15a11 is used to install a water pump. Figure 5 and Figure 6 The front end wall of the water tank 2 is recessed inward to form a second recessed portion 24. The second recessed portion 24 is slightly larger than the first recessed portion 15, but the two have the same shape. A slot 24a is formed on the outside of the second recessed portion 24, and the slot 24a can just accommodate the first recessed portion 15. A sealed water receiving seat 27 is fixedly installed on the top surface of the second recessed portion 24. When the water tank 2 is fixedly placed in the mounting groove 11 of the water tank support 1, the first recessed portion 15 is just inserted into the slot 24a formed by the second recessed portion 24. At the same time, the sealed water receiving seat 27 on the water tank 2 is sealed and connected with the water receiving port 18 on the water tank support 1 to form a water supply channel. The water pump is fixedly installed in the water pump mounting groove 15a11, and its water inlet end is connected to the above-mentioned channel, so that the water in the water tank 2 can be pumped out to the outside through the channel formed by the sealed water receiving seat 27 and the water receiving port 18 to achieve cleaning. This arrangement can make the water pump installation position more reasonable, making it closest to the water source, eliminating excessive piping arrangements, saving space, and facilitating the installation of the water tank 2 and the lightweight design of the secure components.

[0038] A handle 22 is rotatably provided on the water tank 2. The handle 22 is in a U-shaped structure, with both ends thereof spanning across the top opening of the water tank 2 and rotatably connected to both sides of the water tank 2 to facilitate taking the water tank 2.

[0039] Combination Figure 1 In this embodiment, the height of the water tank 2 is greater than the depth of the installation groove 11. When the water tank 2 is placed in the installation groove 11, a part of its upper side extends out from the top of the installation groove 11. The top opening of the installation groove 11 has a flange portion 11b extending horizontally outward. The flange portion 11b surrounds the installation groove 11. The flange portion 11b is fixed with lap blocks 16 at the two corners of the rear side. The lap blocks 16 are used to support the handle 22 of the water tank 2. When the water tank 2 is placed in the installation groove 11, the handle 22 is rotated toward the rear side, and the two ends of the horizontal part of the handle 22 are just supported on the lap blocks 16 at the two corners of the flange portion 11b, so that a gap is maintained between the handle 22 and the flange portion 11b for fingers to be inserted, so that the handle 22 can be easily rotated out.

[0040] In this embodiment, rounded corners 11 a are formed at the four corners of the installation groove 11 , so that the installation groove 11 looks more smooth and beautiful. Similarly, rounded corners 11 a are formed at the four corners of the water tank 2 .

[0041] In this embodiment, the inner wall of the installation groove 11 is evenly provided with multiple positioning ribs 17, and each positioning rib 17 extends vertically from top to bottom. When the water tank 2 is placed in the installation groove 11, the outer wall of the water tank 2 is positioned on the multiple positioning ribs 17 to achieve a more stable limit.

[0042] See also Figure 8 The top cover 21 is arranged at the top opening of the water tank 2. A water injection port 21a is provided on the top cover 21, which is connected vertically. The water injection port 21a can be used to inject water into the water tank 2 without opening the cover. In order to achieve the positioning between the top cover 21 and the water tank 2, downwardly protruding limit blocks 25 are formed at the two side edges of the top cover 21, and limit grooves 26 for the limit blocks 25 to be inserted into are formed on both sides of the upper edge of the water tank 2. When the top cover 21 is closed, the limit blocks 25 are inserted into the limit grooves 26 to prevent the top cover 21 from moving at will.

[0043] Fig. 9 A cross-sectional view of the top cover 21 is shown. The top cover 21 is formed by snapping together an upper cover 211 and a lower cover 212. Both the upper cover 211 and the lower cover 212 are thin plate structures. A first hole 211a is provided on the upper cover 211, and a second hole 212a is provided on the lower cover 212. The first hole 211a and the second hole 212a are sealed and connected to form a water inlet 21a of the top cover 21.

[0044] The lower end surface of the upper cover 211 is provided with a plurality of cylindrical cams 211c, a first bolt hole 211d is provided on the cams 211c, and a plurality of bolt holes 212c corresponding to the cams 211c are provided on the lower cover 212, and a second bolt hole 212d is provided concentrically in the cam hole 212c. When the upper cover 211 and the lower cover 212 are covered, the plurality of cams 211c are inserted into the corresponding cam holes 212c, and then the bolts (not shown) pass through the second bolt holes 212d of the lower cover 212 and are inserted into the first bolt holes 211d of the upper cover 211, thereby fixing the upper and lower covers 212. This arrangement reduces the weight of the top cover 21, forms a hollow structure between the upper cover 211 and the lower cover 212, and supports the two through the cams 211c and the cam holes 212c, thereby achieving a higher compressive strength.

[0045] A first annular groove 211 b is circumferentially formed at the circumferential edge of the upper cover 211 , and a second annular groove 212 b is circumferentially formed at the circumferential edge of the lower cover 212 . The first annular groove 211 b and the second annular groove 212 b are engaged with each other to improve the stable positioning of the upper and lower covers 212 .

[0046] A sealing strip 2a is fixed to the upper end of the water tank 2 to improve the sealing between the water tank 2 and the top cover 21.
