[0038] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly. The connection can be a direct connection or an indirect connection.

[0039] Reference Figure 1-7 The utility model provides a storage tank, comprising a tank body 1 and a movable cover 2; the tank body 1 is provided with a storage cavity 12, and an opening is provided at the upper end of the storage cavity 12; the movable cover 2 covers the opening; the movable cover 2 and the tank body 1 are respectively provided with magnetic structures, so that different storage tanks can be magnetically adsorbed to each other; the tank body 1 and the movable cover 2 are detachably connected.

[0040] Specifically, items are stored in the storage cavity 12, and the movable cover 2 is used to cover the opening to prevent the items in the storage cavity 12 from leaking out of the opening. The magnetic structure allows different storage tanks to be magnetically adsorbed to each other, so that different storage tanks can be spliced ​​together, and they are relatively easy to separate under the action of external force through magnetic adsorption, thereby solving the problem that existing storage tanks are difficult to meet the requirements of being interconnected and easily separated.

[0041] It should be noted that, in some embodiments, the magnetic attraction structures on the movable cover 2 and the tank body 1 are of the same structure; in some embodiments, the magnetic attraction structures on the movable cover 2 and the tank body 1 may be of different types of structures; the magnetic attraction structure may be a fixed magnet, or a flippable magnet, or may include a magnet and a metal part that can be attracted by the magnet, which is determined specifically according to design requirements.

[0042] In some embodiments, the storage tank may be cylindrical; in some embodiments, the storage tank may be rectangular.

[0043] Furthermore, in some embodiments, the storage tank further includes a transfer structure 3, which connects the tank body 1 and the movable cover 2, and the tank body 1 and the movable cover 2 can rotate relative to each other and be separated and combined in the up and down directions through the transfer structure 3.

[0044] Specifically, the transfer structure 3 can be used to achieve that the movable cover 2 is staggered with the opening to facilitate pouring out the items in the storage cavity 12; in some embodiments, the transfer structure 3 includes a structure that enables the tank body 1 and the movable cover 2 to rotate relative to each other and a separation and combination structure for the tank body 1 and the movable cover 2 to separate and combine in the up and down directions, which can be specifically achieved by plugging in a rotating shaft that can allow the tank body 1 and the movable cover 2 to rotate axially and slide up and down relative to each other.

[0045] Further, in some embodiments, the transfer structure 3 includes a rotating rod 31, a compression spring 32 and an extrusion piece 33; the rotating rod 31 is rotatably connected to at least one of the tank body 1 and the movable cover 2, and the rotating rod 31 includes an insertion section, which slides in the up and down directions and is inserted into one of the tank body 1 and the movable cover 2; the compression spring 32 is sleeved on the outside of the insertion section; the extrusion piece 33 is connected to the insertion section and presses against the compression spring 32; the parts of the tank body 1 and the movable cover 2 inserted by the insertion section are provided with a sliding hole 14 and a limiting cavity 15, the sliding hole 14 and the limiting cavity 15 are connected, the aperture of the sliding hole 14 is smaller than the aperture of the limiting cavity 15, the insertion section is inserted into the sliding hole 14 and the limiting cavity 15, the compression spring 32 is arranged in the limiting cavity 15, and the two ends of the compression spring 32 respectively press against the end wall of the extrusion piece 33 and the limiting cavity 15 close to the sliding hole 14.

[0046] Specifically, the limiting cavity 15 is used to accommodate part of the rotating rod 31, the compression spring 32 and the extrusion piece 33. In some embodiments, it also plays a role in guiding the extrusion piece 33 to enable the movable cover 2 to move smoothly. The rotating rod 31 can realize the relative rotation of the tank body 1 and the movable cover 2 through the transfer structure 3 and the separation and combination in the upper and lower directions. The compression spring 32 squeezes the extrusion piece 33, so that the extrusion piece 33 drives the rotating rod 31 to squeeze the movable cover 2 into the tank body 1, so that the movable cover 2 can better cover the opening and prevent the leakage of the items. Moreover, the compression spring 32 drives the rotating rod 31 to pull down the movable cover 2. After the movable cover 2 rotates to a certain angle, the movable cover 2 automatically covers the opening of the tank body 1 under the action of tension. When it is necessary to pour out the items in the storage cavity 12, the movable cover 2 is relatively moved upward by external force to release the connection between the movable cover 2 and the tank body 1. Then, the tank body 1 or the movable cover 2 is relatively moved to stagger the movable cover 2 and the opening, so as to facilitate the pouring out of the items.

[0047] In some embodiments, one end of the rotating rod 31 is rotatably connected to one of the tank body 1 and the movable cover 2, and the other end is inserted into the other and can slide up and down. The other end can be rotatable or can only slide up and down; in some embodiments, one end of the rotating rod 31 is fixedly connected to one of the tank body 1 and the movable cover 2, and the other end is inserted into the other and can rotate and slide up and down.

[0048] Furthermore, in some embodiments, the sliding hole 14 and the limiting cavity 15 are provided on the tank body 1 .

[0049] Specifically, in some embodiments, the sliding hole 14 and the limiting cavity 15 are arranged on the tank body 1. Since the tank body 1 is higher and has more available space above and below, the sliding hole 14 and the limiting cavity 15 are arranged on the tank body 1, which is more conducive to increasing the moving distance of the movable cover 2 in the upper and lower directions. When the insertion depth of the movable cover 2 and the tank body 1 is longer, sufficient moving distance can also be provided.

[0050] Further, in some embodiments, one end of the rotating rod 31 away from the insertion section is fixedly connected to the movable cover 2, and the insertion section is rotatably connected to the tank body 1; or, one end of the rotating rod 31 away from the insertion section is rotatably connected to the movable cover 2; or, one end of the rotating rod 31 away from the insertion section is rotatably connected to the movable cover 2, and the insertion section is rotatably connected to the tank body 1.

[0052] Further, in some embodiments, the insertion section is provided with a mounting hole; the pressing member 33 includes a connecting rod 331 and a pressing piece 332. The connecting rod 331 is inserted into the mounting hole to connect the pressing member 33 to the rotating rod 31, and the pressing piece 332 presses against one end of the compression spring 32.

[0053] Specifically, in some embodiments, the connecting rod 331 is press-fitted into the mounting hole to fixedly connect the pressing member 33 to the rotating rod 31; in some embodiments, the outer surface of the connecting rod 331 is provided with threads, and the inner surface of the mounting hole is provided with internal threads, and the connecting rod 331 is threadedly connected to the insertion section to fixedly connect the pressing member 33 to the rotating rod 31; in some embodiments, the pressing piece 332 is circular, so that the pressing piece 332 can rotate within the limiting cavity 15; in some embodiments, the limiting cavity 15 is significantly larger than the pressing piece 332, so that the pressing piece 332 can rotate within the limiting cavity 15; in some embodiments, the pressing piece 332 is polygonal, and the shape of the limiting cavity 15 is adapted thereto, for the case where the pressing piece 332 can only move up and down within the limiting cavity 15.

To prevent the magnet from entering the limiting cavity 15, an isolation plug 4 is inserted into the end of the limiting cavity 15 facing the second magnet mounting groove 13.

[0060] Further, in some embodiments, the magnet is a flipable magnet.

[0061] Specifically, for the flipable magnet, after the two storage tanks approach each other, adsorption between different magnetic poles is achieved through flipping, which is more convenient for the assembly of the storage tanks.
