[0022] The present invention will be further described below with reference to the embodiments, but is not limited to the contents of the description.

[0023] like Figures 1 to 4In the illustrated embodiment 1, the present invention discloses a detergent box assembly, including a detergent box 10, a return member 20, a valve core 30 and a top column 40. The detergent box 10 has a storage chamber 11 for storing detergent, and a delivery port 12 for delivering detergent is opened on the detergent box 10, and the delivery port 12 is communicated with the storage chamber 11; the return member 20 is located in the storage chamber 11, and a first end of the return member 20 is connected to the inner wall of the storage chamber 11; the valve core 30 is connected to the second end of the return member 20, and the valve core 30 is movable relative to the delivery port 12. The valve core 30 has a first position that closes the delivery port 12 and a second position that opens the delivery port 12, and the valve core 30 switches between the first position and the second position by movement; the top column 40 is movably provided on the detergent box 10, a first end of the top column 40 is connected to the valve core 30, and a second end of the top column 40 is located outside the detergent box 10, and the top column 40 drives the valve core 30 to move by movement.

[0024] Since the detergent box 10 has a storage chamber 11, the storage chamber 11 can be filled with detergent in advance. When in use, the valve core 30 is moved to the second position via the top column 40, allowing the detergent to flow out of the delivery port 12. When not in use, the valve core 30 can be returned to the first position via the return component 20, thereby closing the delivery port 12 and preventing the detergent from flowing out, thereby achieving detergent storage. The detergent box assembly of the present invention integrates the storage and delivery of detergent by providing a delivery port 12 on the detergent box 10, providing the valve core 30 and the top column 40, and then cooperating with the return component 20. Multiple amounts of detergent can be stored in the detergent box 10 at a time, and only the delivery port 12 needs to be opened each time, without having to add detergent each time, thereby greatly reducing the number of washing steps and improving cleaning efficiency.

[0025] It should be noted that the valve core 30 can be spherical or in a cap-like structure. When the valve core 30 is spherical, its diameter can be compatible with the inner diameter of the delivery port 12 or slightly larger than the inner diameter of the delivery port 12. When the valve core 30 is in a cap-like structure, its diameter can be exactly compatible with the delivery port 12 or slightly larger than the size of the delivery port 12, so that the outer edge of the valve core 30 in the cap-like structure directly abuts the inner wall of the storage chamber 11 on the side of the delivery port 12.

[0026] The restoring member 20 includes an elastic member 22 , which is connected between the valve core 30 and the inner wall of the storage chamber 11 . The elastic member 22 is used to reset the valve core 30 to the first position to prevent detergent from leaking out.

[0027] Specifically, the elastic member 22 can be an elastic band or a resilient mesh structure composed of multiple elastic bands. The elastic force maintains the valve core 30 in the first position. When the top post 40 drives the valve core 30 to the second position, the elastic band is stretched. When the top post 40 moves back, the elastic member returns the valve core 30 to the first position. In addition to being an elastic band or a resilient mesh structure, the elastic member can also be a spring or other structure.

[0028] In this embodiment, the return member 20 further includes a telescopic rod 21, and the elastic member 22 is a spring. The spring is sleeved on the telescopic rod 21, with a first end of the spring abutting against the inner wall of the storage chamber 11, and the other end abutting against the valve core 30. By arranging the valve core 30 on the telescopic rod 21, the valve core 30 can be moved along the extension and contraction direction of the telescopic rod 21 under the drive of the top column 40. The spring sleeved on the telescopic rod 21 also serves as a guide, making the process of the spring's elastic deformation pushing the valve core 30 to return to its original position more stable.

[0029] The telescopic rod 21 includes a hollow rod 211 and an extension rod 213. The first end of the hollow rod 211 is connected to the inner wall of the storage chamber 11, and a limiting hole 212 is provided on the hollow rod 211; the first end of the extension rod 213 is inserted into the hollow rod 211, and the second end of the extension rod 213 is connected to the valve core 30. The extension rod 213 is movable relative to the hollow rod 211, and a one-way buckle 214 is provided on the extension rod 213; the extension rod 213 has a first moving direction of extending out of the hollow rod 211 and a second moving direction of retracting into the hollow rod 211. After the extension rod 213 moves to a preset position along the first moving direction, the one-way buckle 214 passes through the limiting hole 212 and forms a limiting fit to limit the extension rod 213 from continuing to move in the first direction. By providing the one-way buckle 214 and the limiting hole 212, the telescopic rod 21 can be prevented from disintegrating under the elastic force of the spring, that is, the extension rod 213 can be prevented from moving too much in the first direction under the elastic force of the elastic member 22 and causing separation from the hollow rod 211, thereby improving the safety and reliability of use.

[0030] It should be noted that if Figure 3 As shown, the structure of the one-way buckle 214 is similar to a wedge structure, which is elastically connected to the extension rod 213. It can be retracted into the extension rod 213 under the action of external force, and can rebound to the outside of the extension rod 213 after the external force disappears. The cross-section of the one-way buckle 214 is triangular, which has a guide slope and a limiting surface. After the extension rod 213 moves to a preset position along the first direction, the one-way buckle 214 enters the limiting hole 212, and the limiting surface is used to cooperate with the inner wall surface of the limiting hole 212 to limit the extension rod 213 to continue to move along the first direction. When the extension rod 213 moves along the second direction, under the cooperation of the hollow rod 211 and the guide slope, the one-way buckle 214 retracts into the extension rod 213 to achieve one-way limiting.

[0031] The detergent box 10 includes a box body 13 and a box cover 14. The box body 13 is provided with an addition port for adding detergent. The box cover 14 is used to close the addition port. The box cover 14 is detachably connected to the box body 13, and the box cover 14 and the box body 13 enclose a storage chamber 11. The provision of the box cover 14 allows the box cover 14 to be opened when detergent is needed and the detergent can be added through the addition port, which facilitates the addition process.

[0032] It should be noted that the addition port can be provided at the end of the box body 13 or at the side of the box body 13. In the above embodiment, the box body 13 is cylindrical, with a closed first end and an addition port at the second end. The box cover 14 is threadedly connected to the second end of the box body 13, and the introduction port 12 is located on the box cover 14. This has the advantage of eliminating the need for a separate opening in the box body 13, simplifying the support process. Moreover, the introduction port 12 is provided on the box cover 14, making processing more convenient and the installation and replacement of the valve core 30 more convenient. Furthermore, because the telescopic rod 21 in the above embodiment is provided with a one-way buckle 214, the telescopic rod 21 will not disintegrate when the box cover 14 is opened, making it more reliable to use.

[0033] In one embodiment (not shown), the structure of the detergent box assembly is the same as that of the above embodiment, except that the addition port of the box body 13 is located on the side wall of the box body 13, and the box cover is snapped onto the addition port, similar to the structure of the battery compartment and battery cover of a remote control. The advantage of this method is that adding detergent is more convenient and quick.

[0034] Of course, in the specific implementation process, it is also possible to simultaneously open an addition port on the second end and the side wall of the box body, and set a box cover 14 on each addition port, so that it can be used according to actual conditions.

[0035] In such Figure 1 and Figure 2 In the illustrated embodiment 1, the detergent box 10 has a first end and a second end that are oppositely disposed. The first end is provided with a handle 50, and the second end is provided with a dispensing port 12. In other words, the first end of the box body 13 constitutes the first end of the detergent box 10, while the second end of the box body 13 is provided with a lid 14, forming the second end of the detergent box 10. The handle 50 is provided at the first end of the box body 13, and the dispensing port 12 is provided on the lid 14. This structure facilitates the insertion of the detergent box 10 into the washing machine, and the handle 50 facilitates the removal of the detergent box 10 from the washing machine.

[0036] like Figure 5 As shown, according to the second embodiment of the present invention, a washing machine is also disclosed, including the above-mentioned detergent box assembly.

[0037] The washing machine also includes a shell 60, which is provided with an inclined installation cavity 61 and a water inlet pipe 62 connected to the installation cavity 61. The shell 60 is also provided with a mounting port 63 connected to the installation cavity 61. The detergent box 10 is movably arranged in the installation cavity 61. The detergent box 10 has a delivery position and a storage position. The detergent box 10 switches between the delivery position and the storage position by movement; the first end of the top column 40 abuts against the valve core 30, and the second end of the top column 40 is provided on the inner wall of the water inlet pipe 62; in the delivery position of the detergent box 10, the top column 40 pushes the valve core 30 to the second position; in the storage position of the detergent box 10, the valve core 30 is reset to the first position.

[0038] Before use, the lid 14 of the detergent box 10 can be opened to add detergent. After adding detergent, the lid 14 is screwed on and the detergent box is installed into the installation cavity 61 . At this time, the top column 40 just touches the valve core 30 .

[0039] When the user uses the washing machine, they press the detergent box filled with detergent. As the detergent box is pressed, the push post 40 pushes the push valve core 30 into the detergent box. At this time, the spring is compressed, and the one-way buckle is pushed inward. Due to the inclined installation cavity 61, the detergent is affected by gravity and flows out of the detergent box from around the push valve core 30. When the user releases their hand, the spring rebounds, the one-way buckle is re-engaged, and the push valve core 30 is prevented from being pushed out of the detergent box by the spring, and the detergent stops flowing out. After the detergent is added, water is allowed to flow into the water inlet valve, flushing the detergent in the water inlet pipe into the washing tub of the washing machine.

[0040] A liquid level probe is installed at the pressing head. When the detergent in the detergent box cannot cover the pressing head, it will remind the user to add detergent.

[0041] It should be noted that fully pressing the detergent drawer is a standard amount. This is because when the drawer is fully pressed, the spring compression is constant. When the finger is released, the spring returns to its original position over a fixed amount of time. During this time, the amount of detergent flowing out of the drawer is also constant. Changing the spring compression coefficient can achieve a standard amount. To adjust the amount of detergent, you can choose the degree of pressing. Pressing halfway or less will dispense halfway or less. You can also press multiple times to add more detergent.

[0042] In addition, in order to increase the flow rate of the detergent, the installation cavity 61 can be set vertically, so that the flow rate of the detergent can be increased under the action of gravity.

[0043] The housing 60 is provided with a plurality of mounting cavities 61, each of which is provided with a detergent box assembly. When the user wants to use more detergents, he can press the multiple detergent boxes. When the user wants to control the amount of detergent, he can add detergent by controlling the force and time of pressing the detergent box.

[0044] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not possible to enumerate all embodiments here. Any obvious variations or modifications arising from the technical solution of the present invention remain within the scope of protection of the present invention.
