[0040] The terms "first", "second", "third" and the like are merely used to distinguish elements of similar nature, and do not indicate or imply relative importance or a particular order.

[0041] The terms "comprises," "comprising," or any other variations thereof, are intended to cover a non-exclusive inclusion of the elements listed and may also include additional elements not expressly listed.

[0042] like Figure 1 As shown, this embodiment provides a stackable and connected water tank, comprising a water tank body 1, a water inlet joint assembly 2, and a sealing valve assembly 3. Water inlets are provided at the top 11 and the bottom 12 of the water tank body 1, and the water inlet joint assembly 2 and the sealing valve assembly 3 are respectively installed at the water inlet 11 and the water inlet 12 of the top 11 and the bottom 12 of the water tank body 1.

[0043] like Figures 2 to 3As shown, the water inlet joint assembly 2 includes a water inlet joint 21, a sealing gasket 22, a filter 23, and a second sealing member 24. The filter 23 is installed at one end of the water inlet joint 21 located inside the water tank body 1 and fixed by the sealing gasket 22. The inner side wall of the water inlet joint 21 is provided with a first threaded portion 25. The water inlet joint 21 is threadedly connected to the water tank body 1 through the first threaded portion 25, and the second sealing member 24 is sleeved on the outer side wall of the water inlet joint 21. The sealing valve assembly 3 includes a valve seat 32, a valve core 31 and a first elastic reset member 33. The inner side wall of the valve seat 32 is provided with a second threaded portion 315. The valve seat 32 is threadedly connected to the water tank body 1 through the second threaded portion 315. The valve seat 32 has a water inlet 321 that connects the inside and outside of the water tank body 1. The water inlet 321 is located in the middle of the valve seat 32 and at one end of the water inlet channel in the middle of the valve seat 32. The valve core 31 can be linearly moved and installed in the water inlet channel of the valve seat 32. The first elastic reset member 33 is sleeved on the valve core 31, and the two ends of the first elastic reset member 33 are respectively against the valve seat 32 and the valve core 31. The valve core 31 blocks the water inlet 321 of the valve seat 32 under the support of the first elastic reset member 33. When two water tank bodies 1 are stacked, the water inlet connector 21 on the lower water tank body 1 can push the valve core 31 on the upper water tank body 1, so that the valve core 31 overcomes the elastic force of the first elastic reset member 33 and moves linearly in the valve seat 32, thereby opening the water inlet 321 of the valve seat 32.

[0044] Through the above structure, the stackable and connected water tanks provided in this embodiment can freely select the corresponding number of water tanks to be stacked together for use according to actual needs. When the water tank bodies 1 of multiple water tanks are stacked together, the water inlet joint 21 of the water tank body 1 located at the bottom pushes the valve core 31 of the water tank body 1 located at the top to move linearly in the valve seat 32, so that the sealing valve assembly 3 is opened, thereby connecting the water paths in the multiple water tank bodies 1. When the water tank body 1 is placed alone without being stacked, the valve core 31 of the water tank body 1 blocks the water inlet 321 of the valve seat 32 under the elastic force of the first elastic reset member 33, that is, the valve seat 32 of the water tank body 1 is in a closed state when it is not stacked for use. In this way, multiple water tanks can be prepared when it is far away from the water source and it is inconvenient to get water. When the water tank body 1 is stacked on the equipment for water supply, when the water in the water tank body 1 located at the top is used up, the empty water tank body 1 stacked at the top is removed, and the water tank body 1 with water is replaced, which is flexible, fast and efficient to use.

[0045] Specifically, Figures 2 to 3As shown, the valve core 31 has a first end 311 and a second end 312 relative to each other, the first end 311 extends into the water tank body 1 through the water inlet 321 of the valve seat 32, and the second end 312 is located in the valve seat 32. The valve core 31 is provided with a connecting port 313 on the side wall between the first end 311 and the second end 312, and the connecting port 313 can connect the inside and the outside of the water tank body 1. The valve seat 32 has a protrusion 322 extending along the periphery of the water inlet 321 toward the axis of the water inlet 321. The valve core 31 is sleeved with a first sealing member 34 at the first end 311. When the first sealing member 34 abuts against the surface of the protrusion 322 of the valve seat 32 close to the first end 311 of the valve core 31, the water inlet 321 of the valve seat 32 is blocked. The first sealing member 34 and the second sealing member 24 can be waterproof sealing rings. The water inlet joint 21 includes a main body 212 and an extension portion 211. The main body 212 of the water inlet joint 21 is located inside the water tank body 1, and the extension portion 211 of the water inlet joint 21 is located outside the water tank body 1. The shape of the extension portion 211 of the water inlet joint 21 is adapted to the shape of the water inlet 321 of the valve seat 32. When two water tank bodies 1 are stacked, the extension portion 211 of the water inlet joint 21 is inserted into the valve seat 32 and abuts against the valve core 31.

[0046] like Figure 3 As shown, when the water tank body 1 is not stacked for use, the first elastic reset member 33 is sleeved on the valve core 31 and its two ends abut against the valve core 31 and the valve seat 32. The valve core 31 is elastically acted on by the first elastic reset member 33 so that the first end 311 of the valve core 31 abuts against the water inlet 321 of the valve seat 32. At this time, the sealing valve assembly 3 of the water tank body 1 is in a blocked state, and the water in the water tank body 1 cannot flow out from the valve seat 32. Figure 5 and Figure 6 As shown, when the water tank bodies 1 are stacked for use, the water inlet connector 21 of the water tank body 1 located at the bottom pushes the valve core 31 of the water tank body 1 located at the top to overcome the elastic force of the first elastic reset member 33, so that the first end 311 of the valve core 31 is separated from the water inlet 321 of the valve seat 32, and a part of the valve core 31 extends into the water tank body 1. At this time, the water in the water tank body 1 located at the top can flow into the water tank body 1 located at the bottom from the connecting port 313 of the valve core 31, thereby completing the stacking connection of the water tank bodies 1.

[0047] Preferably, the surface of the protrusion 322 close to the first end 311 of the valve core 31 is an inclined surface 323, and the inclined surface 323 gradually inclines from the periphery of the water inlet 321 along the axial direction of the water inlet 321 to a direction away from the valve core 31. In this way, when the first sealing member 34 on the valve core 31 abuts against the protrusion 322 of the valve seat 32, a better sealing effect can be achieved.

[0048] For the valve core 31, if Figure 4As shown in the figure, the interior of the valve core 31 is hollow to form a water passage 316, and the second end 312 of the valve core 31 has an opening 317 and the opening 317 is connected to the water passage 316, and the flow port opened on the side wall between the first end 311 and the second end 312 of the valve core 31 can be connected to the water passage 316 of the valve core 31. When the valve core 31 is partially extended into the water tank body 1 under the push of the water inlet joint 21, the communication port 313, the water passage 316 and the opening 317 of the valve core 31 constitute a water path, so that the water in the water tank body 1 located above can flow into the water tank body 1 located below along the water path.

[0049] Regarding the installation of the first elastic return member 33 between the valve seat 32 and the valve core 31, as shown in FIG. Figure 3 As shown, the valve core 31 has an abutting portion 314 extending along the periphery of the second end 312, one end of the first elastic reset member 33 abuts against the abutting portion 314, and the other end of the first elastic reset member 33 abuts against the protrusion 322 of the valve seat 32. When the water tank bodies 1 are not stacked for use, the first elastic reset member 33, under the elastic action, makes the first end 311 of the valve core 31 abut against the water inlet 321 of the valve seat 32, at this time, the first sealing member 34 abuts against the protrusion 322 of the valve seat 32 to achieve sealing. When the water tank bodies 1 are stacked for use, the water inlet connector 21 of the water tank body 1 located at the bottom pushes the abutting portion 314 of the valve core 31 of the water tank body 1 located at the top, so that the valve core 31 overcomes the elastic force of the first elastic reset member 33 and moves linearly in the valve seat 32, and the first end 311 of the valve core 31 gradually moves away from the water inlet 321 of the valve seat 32, so that the two water tank bodies 1 are connected. When the water tank body 1 located at the top is removed, the valve core 31 of the water tank body 1 located at the top has no driving force from the water inlet joint 21, so that the valve core 31 is reset under the elastic action of the first elastic reset member 33, and the first end 311 of the valve core 31 gradually approaches the water inlet 321 of the valve seat 32, and finally achieves the sealing of the water tank body 1 when abutting.

[0050] Furthermore, if Figure 7 As shown, one of the top 11 and the bottom 12 of the water tank body 1 is provided with an embedding portion 13, and the other of the top 11 and the bottom 12 of the water tank body 1 is provided with an embedding groove 14. In this embodiment, the embedding portion 13 is located at the bottom 12 of the water tank body 1, and the embedding groove 14 is located at the top 11 of the water tank body 1. When two water tank bodies 1 are stacked, the embedding portion 13 of the upper water tank body 1 is embedded in the embedding groove 14 of the lower water tank body 1. In this way, when the water tank bodies 1 are stacked for use, it can be ensured that the water tank bodies 1 are firmly connected and will not shake or fall.

[0051] At the same time, if Figures 7 to 9As shown, the two opposite sides of the stackable and connected water tank provided in this embodiment are further provided with a lock unit 4, the lock unit 4 includes a lock portion 41 and a second elastic reset member 43, the water tank body 1 is provided with a mounting block 42 on the side wall between the top 11 and the bottom 12, the mounting block 42 is provided with a lock slot 421 for installing the lock portion 41, the lock portion 41 has a relative connection end 423 and a rotation end 424, the connection end 423 of the lock portion 41 is rotatably connected to the lock slot 421, the rotation end 424 of the lock portion 41 is provided with a lock 411, and the rotation end 424 can rotate around the connection end 423 in the lock slot 421. The opposite ends of the second elastic reset member 43 are respectively connected to the side wall of the water tank body 1 and the side wall of the lock portion 41. The top 11 of the water tank body 1 is provided with a card slot 171 matching the lock 411. When two water tank bodies 1 are stacked for use, the water tank body 1 located on the upper side moves from top to bottom toward the water tank body 1 located on the lower side. At this time, the rotating end 424 of the locking portion 41 rotates around the connecting end 423, so that the rotating end 424 of the locking portion 41 moves toward the direction close to the water tank body 1. When the water tank body 1 located on the upper side is stacked on the water tank body 1 located on the lower side, the locking portion 41 rotates around the connecting end 423 under the elastic drive of the second elastic reset member 43, so that the rotating end 424 is reset to the initial position, thereby being engaged with the slot 171 at the top 11 of the water tank body 1.

[0052] The first elastic return member 33 and the second elastic return member 43 are preferably springs.

[0053] Specifically, Figures 8 to 10As shown, the mounting block 42 is threadedly connected to the water tank body 1 by screws 44, and the side walls of the locking groove 421 of the mounting block 42 are provided with shaft holes 422 on opposite sides, and the two sides of the connecting end 423 of the locking part 41 are provided with pins 412, and the pins 412 of the locking part 41 are inserted into the shaft holes 422 of the locking groove 421, so that the locking part 41 can rotate in the locking groove 421 around the connecting end 423, and the surface of the locking part 41 facing the locking groove 421 is provided with a cross-shaped connecting block 413, and the second elastic reset member 43 is fixed to the locking part 41 by the connecting block 413. The locking part 411 has a first surface 4111 and a second surface 4112 intersecting each other, and the first surface 4111 is closer to the top 11 of the water tank body 1 than the second surface 4112, and the second surface 4112 gradually tilts away from the water tank body 1 in the direction from the bottom 12 of the water tank body 1 to the top 11 of the water tank body 1. The top 11 of the water tank body 1 is provided with a clamping block 17, and a clamping slot 171 is formed on the clamping block 17. The depth direction of the clamping slot 171 is perpendicular to the direction from the top 11 to the bottom 12 of the water tank body 1, and the clamping slot 171 is located on the surface of the clamping block 17 close to the water tank body 1. In this way, when the water tank body 1 located at the top approaches the water tank body 1 located at the bottom, the second surface 4112 of the lock buckle 411 of the lock buckle part 41 first contacts the clamping block 17 of the water tank body 1 located at the bottom. Since the second surface 4112 is an inclined surface, when the second surface 4112 contacts the clamping block 17, the lock buckle 411 drives the rotating end 424 of the lock buckle part 41 to gradually move toward the water tank body 1. When the water tank body 1 is installed in place, the second surface 4112 of the lock buckle 411 is aligned with the clamping groove 171 of the clamping block 17, and the second elastic reset member 43 drives the rotating end 424 of the lock buckle 411 to rotate around the connecting end 423 in the direction away from the water tank body 1, so that the first surface 4111 of the lock buckle 411 is against the top wall of the clamping groove 171, thereby fixing the two water tank bodies 1 in the vertical direction. When the water tank body 1 needs to be separated, the rotating end 424 of the lock portion 41 is moved to move the rotating end 424 of the lock portion 41 around the connecting end 423 toward the water tank body 1. At this time, the first surface 4111 of the lock 411 is separated from the slot 171 of the snap block 17, so that the two water tank bodies 1 can be separated in the vertical direction.

[0054] The two water tank bodies 1 are fixed in the horizontal direction by the embedding portion 13 and the embedding groove 14, and are fixed in the vertical direction by the locking portion 41 and the locking groove 171, so that the two water tank bodies 1 are finally firmly connected.

[0055] At the same time, a handle 15 is installed on the top 11 of the water tank body 1, and the top 11 of the water tank body 1 has a receiving groove 16 for receiving the handle 15. The handle 15 is rotatably installed in the receiving groove 16 and the handle 15 can be rotated so that it is located in the receiving groove 16. The water tank body 1 can be conveniently carried by the handle 15 during operation, and when the water tank bodies 1 are stacked and stored, the handle 15 can be rotated so that the handle 15 is located in the receiving groove 16, without affecting the stacking of the water tank bodies 1.

[0056] In summary, the stackable and connected water tanks provided in this embodiment can conveniently adjust the water storage capacity according to actual use requirements, thereby meeting the needs of various use scenarios. The water tank bodies 1 are firmly connected when stacked, and the water tank bodies 1 are easy and quick to stack and separate.

[0057] like Figures 11 to 13 As shown, the present embodiment further provides a high-pressure cleaning machine, including a cleaning machine body 5 and a stackable and connected water tank as described above, wherein a battery pack assembly 54 and a high-voltage motor pump 53 are installed in the cleaning machine body 5, the battery pack assembly 54 provides power to the high-voltage motor pump 53, a water pumping port 52 is provided on the cleaning machine body 5, and the high-voltage motor pump 53 pumps water outward through the water pumping port 52, and a water inlet joint assembly 2 is provided on the top 11 of the cleaning machine body 5, and the cleaning machine body 5 is connected to the sealing valve assembly 3 on the water tank body 1 through the water inlet joint assembly 2.

[0058] In addition, the cleaning machine body 5 of the high-pressure cleaning machine provided in this embodiment is also equipped with rollers 51, and the high-pressure cleaning machine as a whole can be transported by the rollers 51, so that the whole device can be conveniently moved to the required scene. At the same time, in order to facilitate the transportation of the high-pressure cleaning machine, a telescopic pull rod assembly is also installed on the cleaning machine body 5, and the telescopic pull rod assembly can be adapted to the number of water tank bodies 1 to adjust its length, and a hook 61 is also provided on the telescopic pull rod assembly. When the water tank bodies 1 are stacked, the hook 61 of the telescopic pull rod assembly can also be fixed in the card slot set on the side of the water tank body 1, so that the overall connection of the high-pressure cleaning machine is more firmly.

[0059] In summary, the high-pressure cleaning machine provided in this embodiment can adjust the maximum water storage capacity as needed, and can also fully supply water by using multiple water tank bodies 1 for storing water when the water source is far away.
