[0037] In some embodiments, the dispensing box has a dispensing cavity and a liquid outlet, the liquid outlet communicates with the dispensing port through the dispensing cavity, and the dispensing device further comprises:

[0038] A liquid outlet pipe is connected to the dispensing box and the liquid storage box at two ends respectively, and communicates with the liquid inlet and the liquid outlet at the two ends respectively.

[0039] In some embodiments, the liquid outlet is located in the lower half of the dispensing box, and the cross section of the dispensing cavity is tapered from the dispensing port to the liquid outlet.

[0040] In some embodiments, the dispensing cavity is higher than the liquid inlet as a whole, so that the laundry treatment agent in the dispensing cavity can flow to the liquid storage cavity through the liquid inlet under the action of its own gravity.

[0041] In some embodiments, the non-dispensing position includes a storage position and an intermediate position between the dispensing position and the storage position, and in the storage position, the dispensing box is accommodated in the shell of the laundry treatment device.

[0042] A reserved cavity is formed between the liquid inlet and the cavity top wall of the liquid storage cavity along the height direction of the liquid storage box, and the volume of the reserved cavity is capable of accommodating the laundry treatment agent flowing from the dispensing cavity to the liquid storage cavity when the dispensing box is rotated from the dispensing position to the storage position, without causing the laundry treatment agent to flow out of the air pressure balance hole.

[0043] In some embodiments, the dispensing device further comprises:

[0044] A receiving member is fixedly connected to the liquid storage box, and a receiving groove is formed on one side of the receiving member facing the dispensing box.

[0045] The non-dispensing position includes a storage position and an intermediate position between the dispensing position and the storage position, and in the storage position, part of the dispensing box can be accommodated in the receiving groove.

[0046] In some embodiments, the receiving member is provided with a first connecting lug, and the first connecting lug is provided with a first through hole.

[0047] The liquid storage box is provided with a second connecting lug, and the second connecting lug is provided with a second through hole.

[0048] The dispensing device further comprises:

[0049] A fixing member is arranged in the first through hole and the second through hole to fix the receiving member to the liquid storage box.

[0050] In some embodiments, the dispensing device further comprises:

[0052] In a second aspect, the embodiments of the present application provide a laundry treatment device, comprising:

[0053] A cabinet is provided with an opening; and

[0054] The dispensing device described in any of the above embodiments, the liquid storage box assembly is fixedly connected to the cabinet, and the dispensing box assembly enters and exits the cabinet via the opening to switch between the dispensing position and the non-dispensing position, and in the dispensing position, the dispensing port is exposed outside the cabinet.

[0055] In some embodiments, the non-dispensing position includes a storage position and an intermediate position between the dispensing position and the storage position, and in the storage position, the dispensing box assembly is accommodated in the housing, and the dispensing device further comprises:

[0056] a decorative plate connected to the dispensing box assembly;

[0057] wherein, in the storage position, the outer surface of the decorative plate is flush with the outer surface of the housing.

[0058] Based on the above embodiment, in the dispensing position, the dispensing box assembly seals the air pressure balance assembly, at this time, the user can add laundry treatment agent into the storage cavity through the dispensing opening. As the laundry treatment agent increases, the air pressure in the storage cavity begins to rise, when the liquid level of the laundry treatment agent reaches the liquid inlet, that is, the liquid inlet is filled with the laundry treatment agent and no longer communicates with the dispensing opening, that is, the storage cavity forms a relatively sealed space. At this time, if the user continues to add laundry treatment agent, the air in the storage cavity cannot escape and will be compressed, resulting in rising air pressure.

[0059] In the case of forming a relatively closed space in the storage cavity, if the user continues to add laundry treatment agent to the dispensing opening, because the storage cavity cannot receive more laundry treatment agent through the liquid inlet, the excess laundry treatment agent will be temporarily stored in the dispensing box assembly communicating with the storage cavity, and as the user continues to add laundry treatment agent, the liquid level in the dispensing box assembly will rise, and when it reaches the part close to the dispensing opening, the user can directly see the liquid level of the laundry treatment agent to determine whether to stop adding laundry treatment agent.

[0060] In the non-dispensing position, the dispensing box assembly opens the air pressure balance assembly, that is, as the dispensing box assembly moves to the non-dispensing position, the air pressure balance assembly is opened at this time, the air pressure in the storage cavity begins to balance with the outside air pressure, and as the air pressure decreases, the laundry treatment agent temporarily stored in the dispensing box assembly will flow into the storage cavity due to the decrease of pressure difference, which will cause the liquid level in the dispensing box assembly to decrease. If the user adds too much laundry treatment agent before the dispensing box assembly moves to the non-dispensing position, causing the liquid level to be too high, opening the air pressure balance assembly helps to reduce the liquid level, thereby reducing the risk of laundry treatment agent overflowing from the dispensing opening due to the resetting of the dispensing box assembly to the storage position.

[0086] The implementation, functional features and advantages of the present application will be further described with reference to the embodiments and the accompanying drawings. DETAILED DESCRIPTION

[0087] In order to make the objectives, technical solutions and advantages of the present application clearer, further detailed description will be made to the present application with reference to the embodiments and the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present application and not used to limit the present application.

[0088] In a first aspect, as Figure 1As shown, the present application provides a laundry treatment apparatus 1000, which generally includes a washing machine, a dryer, and a spin dryer, etc. The following embodiment is described taking the laundry treatment apparatus 1000 as a washing machine as an example, and other laundry treatment apparatuses 1000 such as dryers and spin dryers can be similarly considered. The laundry treatment apparatus 1000 includes a cabinet 200 and a dispensing device 100, the main function of the dispensing device 100 is to store and dispense laundry treatment agents (such as laundry detergent, softener, etc.). The cabinet 200 provides a protective shell for the structure inside the laundry treatment apparatus 1000, preventing dust from entering. The cabinet 200 has an opening 200a and a washing port 200b, through which the user can place the clothes to be treated inside the laundry treatment apparatus 1000, and the washing port 200b can be arranged adjacent to the opening 200a. The liquid storage box assembly 10 is fixedly connected with the cabinet 200, ensuring the stability and correct positioning of the liquid storage box assembly 10 in the cabinet 200. The dispensing box assembly 20 enters and exits the cabinet 200 through the opening 200a to switch between the dispensing position and the non-dispensing position. In the dispensing position, the dispensing port 21a is exposed outside the cabinet 200, and by providing the opening 200a on the cabinet 200, the user can easily remove the dispensing box assembly 20 from the dispensing position to dispense the laundry treatment agent into the dispensing port 21a.

[0089] Please continue to refer to Figure 1 , the cabinet 200 and the liquid storage box assembly 10 are connected by screws, which provides a stable and reliable fixing method, ensuring that the liquid storage box assembly 10 is firmly installed in the cabinet 200. The screw connection also allows the liquid storage box assembly 10 to be easily removed for maintenance, replacement or upgrading.

[0090] As shown in Figure 2 , Figure 3 and Figure 4 , in some embodiments, in the storage position, the dispensing box assembly 20 is accommodated in the housing, and the dispensing device 100 further includes a decorative plate 90 connected to the dispensing box assembly 20. The decorative plate 90 can be connected to the dispensing box assembly 20 by magnetic attraction or buckle, which is not limited by the present application. Since the dispensing box assembly 20 is movably connected to the liquid storage box assembly 10, the decorative plate 90 moves together when the dispensing box assembly 20 moves. For example, when the dispensing box assembly 20 is rotatably connected to the liquid storage box assembly 10, the dispensing box assembly 20 can rotate within a certain range relative to the liquid storage box assembly 10, and the dispensing port 21a and the decorative plate 90 can be extended or retracted into the opening 200a during rotation.

[0091] Please continue to refer to Figure 4In the storage position, the outer surface of the decorative plate 90 is flush with the outer surface of the cabinet 200, maintaining the overall appearance of the laundry treatment apparatus 1000, and the decorative plate 90 can cover the dispensing box assembly 20 in the storage position, hide the internal mechanical structure, and provide a more concise appearance. The decorative plate 90 can match the style of the appearance of the cabinet 200, so that the entire apparatus is more visually unified and aesthetically pleasing.

[0092] In a second aspect, referring to Figures 5 to 7 The embodiments of the present application provide a dispensing device 100 for a laundry treatment apparatus 1000, and the design of the dispensing device 100 aims to improve the efficiency and convenience of the laundry treatment apparatus 1000.

[0093] Please continue to refer to Figures 5 to 7 The dispensing device 100 includes a liquid storage box assembly 10 and a dispensing box assembly 20 that are movably connected, i.e., the liquid storage box assembly 10 and the dispensing box assembly 20 are designed in a split type. This design allows the liquid storage box assembly 10 to be located at a lower position of the laundry treatment apparatus 1000, while the dispensing box assembly 20 is located at a higher position. The user pours the treatment agent into the dispensing box assembly 20, and by the action of gravity, the treatment agent flows from the dispensing box assembly 20 into the liquid storage box assembly 10. The split design of the liquid storage box assembly 10 and the dispensing box assembly 20 makes the storage capacity of the liquid storage box assembly 10 larger than that of a one-piece dispensing device 100, which is suitable for large families or users who need to wash clothes frequently. The split design makes the liquid storage box assembly 10 and the dispensing box assembly 20 easier to disassemble and reassemble, which is a great advantage for cleaning. The user can clean the dispensing box assembly 20 more easily.

[0094] As Figure 7 shown, the dispensing box assembly 20 has a dispensing opening 21a. Understandably, the dispensing box assembly 20 can move between a dispensing position (for dispensing laundry treatment agent) and a non-dispensing position. In the dispensing position, the user can dispense laundry treatment agent through the dispensing opening 21a, and the above-mentioned non-dispensing position includes a storage position and an intermediate position between the dispensing position and the storage position. Understandably, in the storage position, the dispensing box assembly 20 is accommodated in the housing of the laundry treatment apparatus 1000, maintaining the overall appearance of the laundry treatment apparatus 1000 and protecting the dispensing box assembly 20 from damage caused by external impact. The dispensing box assembly 20 having the dispensing position and the non-dispensing position provides convenience for the user, allowing the dispensing box assembly 20 to be opened when necessary in order to quickly add or check the inventory of laundry treatment agent.

[0095] As Figures 8-10As shown, the liquid storage box assembly 10 is used to store the laundry treatment agent, and has a liquid storage cavity 11a, which is a space for storing the laundry treatment agent, and a liquid inlet 11b, which is in communication with both the liquid storage cavity 11a and the dispensing opening 21a. The laundry treatment agent added by the user from the dispensing opening 21a flows into the liquid storage cavity 11a through the liquid inlet 11b.

[0096] The laundry treatment device 1000 further comprises a gas pressure balancing assembly 1, at least a part of which is arranged in the liquid storage box assembly 10. In the dispensing position, the dispensing box assembly 20 seals the gas pressure balancing assembly 1, and at the same time, the user can still add the laundry treatment agent through the dispensing opening 21a. Understandably, as the amount of laundry treatment agent increases, the gas pressure in the liquid storage cavity 11a begins to rise. When the liquid level of the laundry treatment agent reaches the liquid inlet 11b, i.e., the liquid inlet 11b is filled with the laundry treatment agent and no longer in communication with the dispensing opening 21a, the liquid storage cavity 11a forms a relatively sealed space. At this time, if the user continues to add the laundry treatment agent, the air in the liquid storage cavity 11a cannot escape and thus is compressed, resulting in a rise in gas pressure.

[0097] Under the condition that a relatively closed space is formed in the liquid storage cavity 11a, if the user continues to add the laundry treatment agent to the dispensing opening 21a, because the liquid storage cavity 11a has already reached its capacity and cannot receive more laundry treatment agent through the liquid inlet 11b, the excess laundry treatment agent will be temporarily stored in the dispensing box assembly 20, which is in communication with the liquid storage cavity 11a. As the user continues to add the laundry treatment agent, the liquid level in the dispensing box assembly 20 will rise, and when it reaches the part close to the dispensing opening 21a, the user can directly observe the liquid level of the laundry treatment agent to determine whether to stop adding the laundry treatment agent.

[0098] In the non-dispensing position, the dispensing box assembly 20 opens the gas pressure balancing assembly 1, i.e., as the dispensing box assembly 20 moves to the non-dispensing position, the gas pressure balancing assembly 1 is opened at this time, and the gas pressure in the liquid storage cavity 11a begins to balance with the atmospheric pressure. As the gas pressure decreases, the laundry treatment agent temporarily stored in the dispensing box assembly 20 will flow into the liquid storage cavity 11a due to the decrease in pressure difference, which will cause the liquid level in the dispensing box assembly 20 to decrease. If the user has added too much laundry treatment agent before the dispensing box assembly 20 moves to the non-dispensing position, causing the liquid level to be too high, opening the gas pressure balancing assembly 1 helps to reduce the liquid level, thereby reducing the risk of the laundry treatment agent overflowing from the dispensing opening 21a due to the resetting of the dispensing box assembly 20 to the storage position.

[0099] As shown in FIG. 1, the laundry treatment device 1000 comprises a main body 100, a liquid storage box assembly 10, a dispensing box assembly 20, and a gas pressure balancing assembly 1. Figure 10 and Figure 11As shown, the air pressure balancing assembly 1 includes an air pressure balancing hole 11c, which is arranged on the cavity top wall of the liquid storage cavity 11a and is higher than the liquid inlet 11b. The air pressure balancing hole 11c is in communication with the liquid storage cavity 11a and the liquid inlet 11b. At least part of the dispensing box assembly 20 can seal the air pressure balancing hole 11c during the movement relative to the liquid storage box assembly 10. In the dispensing position, the dispensing box assembly 20 seals the air pressure balancing hole 11c. At this time, the user can add the laundry treatment agent into the liquid storage cavity 11a through the dispensing opening 21a. With the increase of the treatment agent, the air pressure in the liquid storage cavity 11a begins to rise. When the liquid level of the treatment agent is higher than the liquid inlet 11b, i.e., the liquid inlet 11b is filled with the treatment agent and is no longer in communication with the dispensing opening 21a, i.e., the liquid storage cavity 11a forms a relatively sealed space. At this time, if the user continues to add the laundry treatment agent, the air in the liquid storage cavity 11a cannot escape and thus is compressed, resulting in the rise of the air pressure.

[0100] Please continue to refer to Figure 10 and Figure 11 Since the cavity top wall of the liquid storage cavity 11a is higher than the liquid inlet 11b, a reserved cavity 11f is formed between the cavity top wall of the liquid storage cavity 11a and the liquid inlet 11b in the height direction. The height of the above-mentioned reserved cavity 11f generally refers to the distance between the plane where the highest position of the liquid inlet is located and the plane where the top wall is located. With the increase of the treatment agent, the air pressure in the reserved cavity 11f begins to rise, i.e., the air pressure in the reserved cavity 11f is higher than the atmospheric pressure. The existence of the reserved cavity 11f prevents more treatment agent from entering this space. Since the position of the air pressure balancing hole 11c is higher than the liquid inlet 11b, i.e., the air pressure balancing hole 11c is also in communication with the reserved cavity 11f, the air pressure balancing hole 11c is prevented from being blocked by the treatment agent when the user adds the laundry treatment agent in the dispensing position.

[0101] In the case of forming a relatively closed space in the liquid storage cavity 11a, if the user continues to add the treatment agent to the dispensing opening 21a, since the liquid storage cavity 11a cannot receive more treatment agent through the liquid inlet 11b, the excess treatment agent will be temporarily stored in the dispensing box assembly 20 which is in communication with the liquid storage cavity 11a. With the user continuing to add the treatment agent, the liquid level in the dispensing box assembly 20 will rise (as shown in Figure 11 ), and when reaching the part close to the dispensing opening 21a, the user can directly see the liquid level of the treatment agent to determine whether the addition of the treatment agent should be stopped.

[0102] As Figures 12-14As shown, in the non-dispensing position, the dispensing box assembly 20 opens the air pressure balance hole 11c, that is, as the dispensing box assembly 20 moves to the non-dispensing position, the air pressure balance hole 11c is opened at this time, the air pressure in the liquid storage cavity 11a begins to balance with the outside atmospheric pressure, and the reserved cavity 11f disappears. That is, as the air pressure decreases, the laundry treatment agent previously temporarily stored in the dispensing box assembly 20 will flow into the liquid storage cavity 11a due to the decrease in pressure difference, which will cause the liquid level in the dispensing box assembly 20 to decrease. If the user adds too much laundry treatment agent before the dispensing box assembly 20 moves to the non-dispensing position, causing the liquid level to be too high, opening the air pressure balance hole 11c helps to lower the liquid level, thereby reducing the risk of laundry treatment agent overflowing from the dispensing port 21a due to the dispensing box assembly 20 resetting to the storage position.

[0103] Through the air pressure balance mechanism, the dispensing device 100 can prevent the laundry treatment agent from overflowing from the dispensing port 21a during the movement of the dispensing box assembly 20, improving the safety of use. It helps to reduce the overflow and leakage of laundry treatment agent, and keeps the appearance of the laundry treatment equipment 1000 clean.

[0104] In one form of arrangement, the dispensing box assembly 20 is in sliding connection with the liquid storage box assembly 10, the dispensing box assembly 20 is provided with a guide rail, and the liquid storage box assembly 10 can slide along the guide rail to realize switching between the dispensing position and the non-dispensing position, and the liquid storage box assembly 10 is fixedly connected with a sliding block, when the liquid storage box assembly 10 slides relative to the dispensing box assembly 20 to the dispensing position, the sliding block seals the air pressure balance hole 11c, and when the liquid storage assembly slides relative to the dispensing box assembly 20 to the non-dispensing position, the sliding block opens the air pressure balance hole 11c. In order to make the sliding block abut and seal the air pressure balance hole 11c in the dispensing position, a spring can be provided between the sliding block and the dispensing box assembly 20, so that when the dispensing box assembly 20 moves towards the dispensing position, the spring is gradually compressed, so that the sliding block seals the air pressure balance hole 11c.

[0105] It can be understood that the dispensing box assembly 20 and the liquid storage box assembly 10 described above can directly seal the air pressure balance hole 11c or indirectly seal the air pressure balance hole 11c through relative rotation or relative sliding connection, which is not limited in the present application. Further, if the volume of the liquid storage box 11 is large, and the air pressure balance hole 11c is arranged at a position far from the dispensing box 21, the air pressure balance assembly 1 further comprises an auxiliary balance hole 12a1 and a conduit 13. The auxiliary balance hole 12a1 can be provided on the liquid storage box assembly 10. It can be understood that the auxiliary balance hole 12a1 is closer to the dispensing box assembly 20 than the air pressure balance hole 11c, and one end of the conduit 13 communicates with the air pressure balance hole 11c and the other end communicates with the auxiliary balance hole 12a1. During the movement of the dispensing box assembly 20, at least part of the auxiliary balance hole 12a1 is sealed, that is, the air pressure balance hole 11c is indirectly sealed by arranging the auxiliary balance hole 12a1 and the conduit 13.

[0106] As Figure 15 and Figure 16 shown, in another arrangement, the dispensing cartridge assembly 20 is rotatably connected to the reservoir cartridge assembly 10. Specifically, the reservoir cartridge assembly 10 includes a reservoir cartridge 11 having the reservoir chamber 11a and the liquid inlet 11b as described above, and the dispensing cartridge assembly 20 includes a dispensing cartridge 21 and a rotating arm 22, the rotating arm 22 is fixedly connected to the dispensing cartridge 21 with its free end bent towards the reservoir cartridge 11, and the rotating arm 22 is rotatably connected to the reservoir cartridge 11. When the dispensing cartridge assembly 20 is rotated to the dispensing position, the rotating arm 22 is away from the gas pressure equalization hole 11c of the reservoir cartridge 11, i.e. the rotating arm 22 has a free end which can be used to seal the gas pressure equalization hole 11c. By using the rotating arm 22 to achieve the sealing function, the mechanical structure design can be simplified, the number of components required can be reduced, and thus the complexity and cost of the overall dispensing device 100 can be reduced. Further, the user only needs to simply rotate the dispensing cartridge assembly 20 to the dispensing position to add the treatment agent into the dispensing opening 21a, which is easy to operate without complex steps or tools.

[0107] Please refer to Figure 9 , Figure 13 and Figure 15 , the gas pressure equalization assembly 1 includes a breather 12 connected to the reservoir cartridge 11, the breather 12 has a breather passage 12a passing through the breather 12, the breather passage 12a has an auxiliary equalization hole 12a1 formed on the bottom wall of the breather 12, one end of the conduit 13 is in communication with the gas pressure equalization hole 11c, and the other end is connected to the breather 12 and in communication with the auxiliary equalization hole 12a1 through the breather passage 12a, wherein the auxiliary equalization hole 12a1 is located on the rotating path of the rotating arm 22, and the rotating arm 22 seals the gas pressure equalization hole 11c by closing the auxiliary equalization hole 12a1, which can achieve efficient sealing because the rotating arm 22 can directly close the auxiliary equalization hole 12a1 to indirectly seal the gas pressure equalization hole 11c without directly sealing the gas pressure equalization hole 11c. The gas pressure equalization hole 11c is also preferably located on the reservoir cartridge 11 without being limited to being located on the rotating path of the rotating arm 22.

[0108] The above-mentioned arrangement of the breather 12 and the conduit 13 provides a flexible gas pressure management approach, which can adapt to reservoir cartridge assemblies 10 of different sizes and shapes, providing solutions for dispensing devices 100 of various sizes, improving versatility and adaptability.

[0109] In the embodiment, the vent 12 is arranged closer to the dispensing box 21 than the air pressure balance hole 11c, the rotating arm 22 does not need to be arranged too long, less material can be used, thereby reducing the manufacturing cost, and the shorter rotating arm 22 is lighter than the longer rotating arm 22, which helps to reduce the weight of the entire dispensing device 100. When the rotating arm 22 is longer, it is more likely to bend and twist, and the shorter rotating arm 22 reduces the above risk and improves the rotational stability of the rotating arm 22.

[0110] Understandably, the conduit 13 can be an elastic conduit 13, which can be freely bent to adapt to different installation positions and space layouts, the flexibility of the elastic conduit 13 makes it more flexible during installation and adjustment, and can adapt to different space and angle requirements. And the elastic conduit 13 can form a better sealing effect at the connection, reducing the possibility of air leakage.

[0111] As shown in Figure 15 To achieve the rotational connection between the rotating arm 22 and the liquid storage box 11, the liquid storage box 11 is provided with a first rotating shaft hole 11d, and the rotating arm 22 has a second rotating shaft hole 22a, and the dispensing box assembly 20 further comprises a rotating shaft 23, which is inserted into the first rotating shaft hole 11d and the second rotating shaft hole 22a, so that the rotating arm 22 can rotate relative to the liquid storage box 11. The rotating shaft 23 can provide a stable rotating mechanism and ensure that the rotating arm 22 does not deviate or loosen during rotation. And because the connection between the rotating arm 22 and the liquid storage box 11 is more direct and compact, the response speed of the rotating arm 22 when rotating will be improved.

[0112] Specifically, the liquid storage box 11 is provided with a sunken table, the liquid storage box 11 has a mounting seat protruding into the sunken table, the mounting seat is provided with a mounting groove, the vent 12 is arranged in the mounting groove, the vent 12 has a gap with the groove wall of the mounting groove, and the groove wall of the mounting groove is provided with the first rotating shaft hole 11d on the side close to the dispensing box 21. It should be noted that in the upward and downward direction of the liquid storage box 11, the upper surface of the mounting seat is lower than the upper surface of the liquid storage box 11, that is, even if the rotating arm 22 rotates in the first rotating shaft hole 11d, it will not cover the slot of the mounting groove, so that the conduit 13 can extend into the gap through the slot of the mounting groove and be connected with the vent 12.

[0113] As shown in Figure 16 and Figure 17As shown, in some embodiments, the rotating arm 22 comprises a connecting portion 221 and a limiting portion 222, the connecting portion 221 is connected to the delivery box 21, the connecting portion 221 has a second rotating shaft hole 22a, which provides a stable support and connection point for the delivery box 21, allowing the delivery box 21 to rotate within a certain angle range to adapt to different use requirements. The limiting portion 222 is connected to the end of the connecting portion 221 away from the delivery box 21, and the limiting portion 222 can abut against the ventilation portion 12 to close the auxiliary balance hole 12a1. The limiting portion 222 can be designed to be compatible in size and shape with the ventilation portion 12, increasing the flexibility of the design.

[0114] As shown in Figure 9 , Figure 13 and Figure 15 , in this embodiment, to further improve the effect of the rotating arm 22 sealing the auxiliary balance hole 12a1, the delivery box assembly 20 further comprises a first sealing member 24 connected to the limiting portion 222 for sealing the auxiliary balance hole 12a1. Understandably, the first sealing member 24 is a resilient first sealing member 24, and the provision of the first sealing member 24 can reduce the wear caused by the direct collision of the limiting portion 222 against the ventilation portion 12, and the first sealing member 24 can provide a certain buffering effect to absorb impact and vibration.

[0115] The resilient material of the first sealing member 24 can adapt to auxiliary balance holes 12a1 of different shapes and sizes, and the first sealing member 24 can provide a more tight and reliable sealing effect, especially in the case where there may be a small gap between the auxiliary balance hole 12a1 and the limiting portion 222. Understandably, the first sealing member 24 can be a gasket, and the size of the gasket facing the auxiliary balance hole 12a1 is larger than the size of the auxiliary balance hole 12a1. For example, the auxiliary balance hole 12a1 is a circular auxiliary balance hole 12a1, and the gasket is a square gasket that can cover the circular auxiliary balance hole 12a1, which can better cover the auxiliary balance hole 12a1 and provide a more comprehensive sealing effect.

[0116] Please continue to refer to Figure 9 , Figure 13 and Figure 15 , the first sealing member 24 can be connected to the limiting portion 222 by adhesion or sleeving. The adhesion operation is simple, and the connection between the first sealing member 24 and the limiting portion 222 can be quickly completed. When the first sealing member 24 needs to be replaced later, it can be achieved by removing the old adhesive and re-adhering the new first sealing member 24. While the sleeving does not require adhesives, the installation process is convenient and fast.

[0117] As shown in Figure 13 and Figure 16As shown in some embodiments, the surface on which the auxiliary balance hole 12a1 is located is the first abutting surface 121, the limiting portion 222 has a second abutting surface 2221 for mounting the first sealing member 24, both the first abutting surface 121 and the second abutting surface 2221 are planes, and good sealing contact can be provided between the planes, which helps to achieve a more reliable sealing effect. Moreover, the plane design can improve durability, because the contact wear between the planes is generally more uniform than the wear of curved surface contact. In other embodiments, the first abutting surface 121 and the second abutting surface 2221 can be adapted arcs or curved surfaces, which are not limited in the present application.

[0118] As shown in some embodiments, Figure 9 and Figure 15 In some embodiments, the dispensing box assembly 20 further comprises an elastic member 25 connected to the rotating shaft 23, the elastic member 25 has a tendency to make the limiting portion 222 and the first sealing member 24 abut against the auxiliary balance hole 12a1, so that in the dispensing position, the first sealing member 24 continuously seals the auxiliary balance hole 12a1. By continuously applying pressure through the elastic member 25, the accidental leakage risk between the first sealing member 24 and the auxiliary balance hole 12a1 can be reduced, so that the sealing effect is maintained in the dispensing position. Moreover, the user does not need to manually apply force to maintain the seal, and the elastic member 25 provides an automatic sealing mechanism.

[0119] As shown in some embodiments, Figure 9 and Figure 13 In some embodiments, the elastic member 25 is a torsion spring, which is sleeved on the rotating shaft 23. The torsion spring can provide continuous restoring force to ensure that the limiting portion 222 and the first sealing member 24 can be tightly pressed against the auxiliary balance hole 12a1 when the dispensing box assembly 20 is rotated to the dispensing position, thereby achieving effective sealing. Moreover, one end of the torsion spring abuts against the dispensing box 21, and the other end of the torsion spring abuts against the liquid storage box 11 or the vent 12. That is, once the user releases the dispensing box 21, the torsion spring will apply force in the direction of the dispensing box 21, so that the dispensing box assembly 20 moves to the dispensing position. This ensures that the rotating arm 22 is in sealing cooperation with the auxiliary balance hole 12a1, and ensures that the dispensing box assembly 20 is correctly positioned before adding the laundry treatment agent, thereby reducing the possibility that the user starts to add the laundry treatment agent without remembering to move the dispensing box assembly 20 to the dispensing position. The user does not need to spend extra time and effort to manually position the dispensing box assembly 20 to the dispensing position, and the setting of the torsion spring improves the efficiency of the entire process of adding the laundry treatment agent.

[0120] Please continue to refer to Figure 9 , Figure 13 and Figure 15In some embodiments, the dispensing device 100 further comprises a card seat 30 and a card tongue 40. The card seat 30 is arranged on one of the liquid storage box 11 and the dispensing box 21, and has a card slot. The card tongue 40 is arranged on the other one of the liquid storage box 11 and the dispensing box 21, and is detachably connected with the card slot. This reduces the accidental movement of the dispensing box 21 in the storage position, and improves the use safety of the clothes treatment equipment 1000. Moreover, the detachable connection of the card tongue 40 and the card slot allows repeated use, and can be unlocked or locked as needed.

[0121] Specifically, the card tongue 40 can be connected to the liquid storage box 11 near the side close to the dispensing box 21. The liquid storage box 11 is provided with a groove, and the card seat 30 is arranged in the groove. When the card tongue 40 rotates towards the card seat 30, the card tongue 40 can be buckled in the card seat 30, so that the relative position between the liquid storage box 11 and the dispensing box 21 can be maintained in the storage position, and accidental movement is prevented.

[0122] Since the torsional spring continuously applies an outward rotating force to the dispensing box 21, the dispensing box 21 can be locked when it rotates to the storage position. The cooperation of the card tongue 40 and the card seat 30 can resist the force of the torsional spring to twist the rotating shaft 23 outward, and prevent the torsional spring from popping it out again. The locking mechanism ensures that the dispensing box 21 remains in the storage state when it is not necessary to add clothes treatment agent, thereby preventing the clothes treatment agent in the dispensing box 21 from leaking or the user from misoperation.

[0123] As shown in Figure 9 and Figure 10 In this embodiment, the dispensing box 21 has a dispensing cavity 21b and the dispensing opening 21a. The dispensing cavity 21b is in communication with the dispensing opening 21a and the liquid inlet 11b, and the overall height of the dispensing cavity 21b is higher than that of the liquid inlet 11b. This allows the clothes treatment agent in the dispensing cavity 21b to flow to the liquid storage cavity 11a under the action of its own gravity through the liquid inlet 11b, simplifies the dispensing process, improves the dispensing efficiency, reduces the possibility of residual clothes treatment agent in the dispensing cavity 21b, and improves the use efficiency of the clothes treatment agent. Because the clothes treatment agent input from the dispensing opening 21a can directly flow to the liquid storage cavity 11a, the situation that the clothes treatment agent flows too slowly and is blocked in the dispensing opening 21a is reduced.

[0124] As shown in Figure 10 and Figure 11As shown, in the present embodiment, the volume of the reserved cavity 11f is designed to be able to accommodate the laundry treatment agent flowing from the dispensing cavity 21b to the storage cavity 11a when the dispensing box 21 is moved from the dispensing position to the storage position, and not to cause the laundry treatment agent to flow out of the air pressure balance hole 11c, the volume of the reserved cavity 11f is at least greater than the volume between the liquid inlet 11b and the highest point of the dispensing opening 21a, so that the user does not have to worry about the laundry treatment agent overflowing from the air pressure balance hole 11c during operation, thereby improving the safety of using the laundry treatment device 1000.

[0125] As shown in Figure 19 , it can be understood that, along the height direction of the storage box 11, the air pressure balance hole 11c can be arranged on the top wall of the storage box assembly 10 and penetrates the cavity top wall of the storage cavity 11a, so that the flowing laundry treatment agent does not exceed the cavity top wall of the storage cavity 11a, thereby reducing the occurrence of the laundry treatment agent overflowing from the air pressure balance hole 11c.

[0126] As shown in Figure 15 , Figure 16 and Figure 19 , in some embodiments, the dispensing box 21 also has a liquid outlet 21c in communication with the dispensing cavity 21b, the liquid outlet 21c is in communication with the dispensing opening 21a through the dispensing cavity 21b, and the dispensing device 100 further comprises a liquid transfer pipe 50, both ends of which are connected to the dispensing box 21 and the storage box 11, respectively, and are in communication with the liquid inlet 11b and the liquid outlet 21c, respectively, so that the laundry treatment agent in the dispensing cavity 21b can quickly flow into the storage cavity 11a of the storage box 11 through the liquid transfer pipe 50 during the movement of the dispensing box 21 relative to the storage box 11, without being affected by the movement of the dispensing box 21. It can be understood that, in order to facilitate the connection of the liquid transfer pipe 50, the storage box 11 has a liquid transfer portion protruding from the outer surface, the liquid transfer portion has the above-mentioned liquid outlet 21c, the dispensing box 21 has a liquid inlet portion protruding from the outer surface, the liquid inlet portion has the above-mentioned liquid inlet 11b, and both ends of the liquid transfer pipe 50 can be respectively sleeved on the liquid transfer portion and the liquid inlet portion, thereby maintaining the stability of the liquid transfer pipe 50.

[0127] Please refer to Figure 15 , Figure 16 and Figure 19 , in order to improve the efficiency of the laundry treatment agent flowing from the dispensing box 21 to the storage box 11, the liquid outlet 21c and the liquid inlet 11b are both provided with two, the two liquid inlets 11b are arranged on both sides of the air passage portion 12, and the two liquid inlets 11b and the two liquid outlets 21c are arranged one by one, thereby simplifying the connection design of the liquid transfer pipe 50 and facilitating installation and maintenance. The provision of two liquid transfer pipes 50 can increase the flow of the laundry treatment agent and speed up the transfer speed of the laundry treatment agent.

[0128] Further, the infusion tube 50 is an elastic infusion tube 50, which can be freely bent to adapt to the active placement of the cartridge 21, and the flexibility of the elastic infusion tube 50 makes it more flexible during installation and adjustment, which can adapt to different space and angle requirements. And the elastic infusion tube 50 can form a better sealing effect at the connection with the liquid inlet and the infusion part, reducing the possibility of liquid leakage. And the elastic infusion tube 50 can absorb and buffer certain mechanical vibration, reduce the transmission of vibration to other components, thereby reducing noise and prolonging the service life of the placement device 100.

[0129] The outer shape of the liquid storage box 11 can be generally rectangular, which is easier to manufacture and process through a mold, simplifying the production process. Along the height direction of the clothes treatment equipment 1000, the liquid inlet 11b is arranged on the side of the liquid storage box 11 facing the placement cartridge 21, which simplifies the connection of the infusion tube 50, and the air pressure balance hole 11c is arranged on the top of the liquid storage box 11 and communicates with the internal liquid storage cavity 11a, which can better release the internal gas and reduce the risk of overflow.

[0130] As shown in Figure 16 and Figure 18 In this embodiment, the infusion port 21c is arranged in the lower half of the placement cartridge 21, and the cross section of the placement cavity 21b is tapered from the placement port 21a to the infusion port 21c, which helps the clothes treatment agent in the placement cavity 21b to flow to the infusion port 21c, reduces the liquid retention in the placement cavity 21b, and also makes the cleaning of the placement cavity 21b more convenient and reduces the cleaning dead angle. By guiding the clothes treatment agent to flow along the tapered cavity, the flow rate of the clothes treatment agent can be accelerated, and the flow efficiency can be improved. Understandably, the shape of the placement cavity 21b can be funnel-shaped, which effectively guides the clothes treatment agent to flow to the infusion port 21c and reduces the splashing of the clothes treatment agent.

[0131] As shown in Figure 14 and Figure 15 In some embodiments, in order to reduce the evaporation of the clothes treatment agent in the placement cartridge 21 through the placement port 21a in the storage position, the placement device 100 further comprises a storage member 60, which is fixedly connected to the liquid storage box 11. The side of the storage member 60 facing the placement cartridge 21 has a storage groove 60a, and in the storage position, part of the placement cartridge 21 can be accommodated in the storage groove 60a, that is, the part of the placement cartridge 21 with the placement port 21a is accommodated in the storage groove 60a, which can reduce the surface area of the clothes treatment agent exposed to the air, thereby reducing its evaporation and helping to maintain the chemical stability and effectiveness of the clothes treatment agent. The storage member 60 helps to close the placement port 21a, thereby controlling the diffusion of the clothes treatment agent and reducing pollution.

[0132] As shown in Figure 15As shown, in some embodiments, the receiving component 60 is provided with a first connecting ear 61, which has a first through hole 61a. The liquid storage box 11 is provided with a second connecting ear 111, which has a second through hole 111a. The dispensing device 100 also includes a fixing member 70, which passes through the first through hole 61a and the second through hole 111a to fix the receiving component 60 to the liquid storage box 11. Two first connecting ears 61 and two second connecting ears 111 are provided. The two first connecting ears 61 are located on both sides of the receiving component 60 along its length, and the two second connecting ears 111 correspond one-to-one with the two first connecting ears 61. Providing two fixing members 70 helps to enhance the connection stability between the receiving component 60 and the liquid storage box 11, reducing loosening or displacement during use. It also reduces wear on individual fixing members 70, extending the service life of the liquid storage box 11 and the receiving component 60.

[0133] like Figure 14 As shown, to further improve the sealing effect of the receiving container 60 at the dispensing port 21a, the dispensing device 100 also includes a second seal 80. The second seal 80 is disposed on the bottom wall of the receiving container 60a, and in the stored position, the second seal 80 seals against the wall of the dispensing port 21a. The second seal 80 provides an additional sealing layer, effectively preventing the laundry detergent in the dispensing box 21 from evaporating or leaking through the dispensing port 21a. The second seal 80 also protects the wall of the dispensing port 21a from scratches or damage, thereby improving the durability of the dispensing device 100.

[0134] Understandably, the second seal 80 can be a sealing ring. The sealing ring has a certain degree of elasticity and can fit tightly against the wall of the inlet 21a to achieve a better sealing effect. The elastic sealing ring is usually made of durable materials, such as rubber or silicone, which have good chemical resistance and weather resistance, extending the service life of the sealing ring.

[0135] like Figure 20 As shown, in some embodiments, the liquid storage box 11 also has a liquid outlet 11e communicating with the liquid storage chamber 11a. The dispensing device 100 also includes a liquid pump, which is connected to the liquid outlet 11e and is used to pump the laundry detergent into the laundry treatment chamber of the laundry treatment device 1000. The liquid pump can precisely control the amount of laundry detergent pumped to ensure that the laundry treatment chamber receives an appropriate amount of detergent, thereby improving the washing effect. Furthermore, by setting an automated liquid pump, the operation process is simplified, waste caused by over-addition is reduced, and ease of use is improved.

[0136] The liquid outlet 11e can be arranged at the bottom of the liquid storage box 11 or a position close to the bottom. Arranging the liquid outlet 11e at the bottom or a position close to the bottom can make the laundry treatment agent in the liquid storage box 11 be discharged as much as possible, reduce residue, and improve the use efficiency of the laundry treatment agent. In addition, the laundry treatment agent can be naturally discharged by gravity. Compared with being arranged above the liquid storage box 11, the energy required for the liquid pump to suck can be reduced, and the energy consumption can be reduced.

[0137] In some embodiments, a liquid level sensor is arranged in the liquid storage cavity 11a. When the liquid level is too low, the liquid level sensor can trigger a reminder to inform the user to add more laundry treatment agent. Arranging the liquid level sensor can help reduce the maintenance requirements of the laundry treatment device 1000 caused by the liquid level.
