The detergent box provided by the invention is provided with the two box bodies which are separated from each other up and down and can be opened and closed independently, so that the defect that the detergent box in the prior art is easily misplaced or detergents with different purposes are mixed when the detergents are put in can be effectively prevented, and the convenience of use of a user is improved.

For example, the first box 1 may be used for dispensing detergent (such as laundry detergent, washing powder, etc.), and the second box 2 may be used for dispensing softener, etc. When specifically using, the user can open first box body 1 and second box body 2 respectively, makes the opening of corresponding box body expose to put in corresponding washing articles for use, put in the back and close along with the hand, the detergent problem of misplacing or mixing can not appear.

Preferably, the first container 1 and the second container 2 are pivotally opened and closed (see fig. 3 and 4). Compared with the drawer type structure in the prior art, the switch in a pivoting mode has the advantages that the resistance in the switch process is obviously reduced, the switch is smoother, and the operation of a user is easier.

For example, the first container 1 and the second container 2 are pivotally mounted, preferably with the pivot axis vertical, so that the first container 1 and the second container 2 can maintain the container opening upward in any state between and on opening, and thus meet the capacity requirement.

In practice, the first container 1 and the second container 2 can be pivoted around different axes, for example, the pivoting axes are located on the left side and the right side, so that the two containers can be opened towards different pivoting directions.

Preferably, however, said first 1 and said second 2 packet are pivotable with respect to each other about the same axis, as shown in figures 3 and 4. For example, the pivots of the first container 1 and the second container 2 are on the same side and the axes coincide so that they are preferably openable towards the same pivoting direction. With this arrangement, the installation of the first case 1 and the second case 2 can be simplified, for example, pivoting structures can be provided on the first case 1 and the second case 2 to be engaged with each other, and the first case 1 and the second case 2 can be installed on the same pivot.

Preferably, the first box 1 and the second box 2 are both cylindrical structures.

The first boss 13 may be disposed outside the box wall 11 of the first box 1, or may be disposed inside the box wall 11 (as shown in fig. 5 and 6). Obviously, the solution of arranging the first sleeve portion 13 inside the box wall 11 is more preferable, which does not affect the overall appearance of the whole detergent box and is therefore more aesthetic (see fig. 1-4), while also not occupying additional space.

Similarly, in order to facilitate the engagement with the pivot shaft 5, the second container 2 includes a second sleeve portion 23, and the second container 2 is sleeved on the pivot shaft 5 with an inner hole of the second sleeve portion 23. The second sleeve portion 23 may be disposed outside the box wall 21 of the second box 2, or may be disposed inside the box wall 21 (as shown in fig. 7 and 8). Obviously, the solution of arranging the second collar portion 23 inside the box wall 21 is more preferable, which does not affect the overall appearance of the whole detergent box and thus is more aesthetic (see fig. 1-4), while not occupying additional space.

Preferably, in order to better fix the first and second cases 1 and 2 and to more conveniently install the detergent box itself in the washing machine, the detergent box of the present invention further includes a first base 3 and a second base 4, as shown in fig. 1-4, 9-10. Wherein, the first base 3 is arranged above the first box body 1 and is relatively fixed with the upper end of the pivot 5; the second base 4 is installed below the second casing 2 and is fixed to the lower end of the pivot 5.

Preferably, the pivot 5 may have an inner hole extending axially, that is, the pivot 5 may be a hollow structure, and the liquid outlet of the first box body 1 and/or the second box body 2 can communicate with the inner hole of the pivot 5. By skillfully utilizing the inner space of the pivot 5, the appearance of the detergent box of the invention can be optimized, so that the detergent box is more concise and beautiful. In practical implementation, the inner hole of the pivot 5 can directly penetrate through the lower end face of the pivot 5 and serve as a final liquid discharge outlet which is communicated with the inside of a washing drum of the washing machine. Of course, the final drainage outlet may also be provided on a side wall near the lower end face of the pivot shaft 5, as long as it is exposed in the assembled state.

Preferably, as shown in fig. 9, the inner hole side wall of the pivot 5 is provided with a liquid through

port

51, 52 in the middle and at the bottom, respectively, and for example, the liquid outlet 14 of the first box 1 and the liquid outlet of the second box 2 correspond, respectively, and when the first box 1 and/or the second box 2 are in the closed position, the liquid outlet of the first box 1 and/or the second box 2 is communicated with the liquid through port. Obviously, in order to realize this solution, the liquid outlet 14 of the first box 1 and the liquid outlet of the second box 2 are preferably arranged on respective boss portions, i.e. the liquid outlet 14 of the first box 1 is arranged on the first boss portion 13 (as shown in fig. 4), and the liquid outlet (not shown) of the second box 2 is arranged on the second boss portion 23.
