[0063] To make the above objects, features, and beneficial effects of the embodiments of the present invention more obvious and understandable, the following will describe the specific embodiments of the present invention in detail with reference to the drawings.

[0064] Refer to Figure 1 , a schematic diagram of the structure of a detergent box assembly in an embodiment of the present invention is given. Figure 2 It is Figure 1 an exploded view of. Refer to Figure 3 , a schematic diagram of the structure of a lower rail cover in an embodiment of the present invention is given. Refer to Figure 4 , a partial structure schematic diagram of a lower rail cover in one perspective in an embodiment of the present invention is given. Refer to Figure 5 , a partial structure schematic diagram of a lower rail cover in another perspective in an embodiment of the present invention is given. Refer to Figure 6 , a top view of a lower rail cover in an embodiment of the present invention is given. The following will describe the structure of the detergent box assembly in combination with Figures 1 to 6 .

[0065] In a specific implementation, the detergent box assembly 1 may include a housing mechanism 10, a cartridge mechanism 20, a pop-up mechanism 30, and a locking mechanism.

[0066] The housing mechanism 10 has a first accommodation cavity 11, and the first accommodation cavity 11 can accommodate the cartridge mechanism 20, that is, the cartridge mechanism 20 can be placed in the first accommodation cavity 11 of the housing mechanism 10.

[0067] The pop-up mechanism 30 is respectively coupled to the cartridge mechanism 20 and the locking mechanism.

[0068] The locking mechanism is respectively coupled to the housing mechanism 10 and the cartridge mechanism 20. The locking mechanism may include: a track 41, a track converter 42, and an actuating assembly 43, wherein:

[0069] The track 41 may include a locking end 411, a release end 412, a first portion 413, and a second portion 414. The first portion 413 and the second portion 414 are respectively connected to the locking end 411 and the release end 412 from both sides, so that the locking end 411, the release end 412, the first portion 413, and the second portion 414 form a loop. The release end 412 can define the maximum pop-up displacement of the cartridge mechanism 20 relative to the housing mechanism 10, and the locking end 411 can define the movement of the cartridge mechanism 20 relative to the housing mechanism 10, so that the cartridge mechanism 20 is in a locked state.

[0070] The track converter 42 may include a direction conversion portion 421 and a guiding portion 422. The guiding portion 422 can slide along the track 41. The direction conversion portion 421 can adjust the sliding position of the guiding portion 422 on the track 41. When the guiding portion 422 is located at the locking end 411, the cartridge mechanism 20 is in a locked state.

[0071] The actuating assembly 43 is respectively coupled to the pop-up mechanism 30, the track converter 42, and the cartridge mechanism 20. The actuating assembly 43 can drive the cartridge mechanism 20 to move relative to the housing mechanism 10 under the drive of the pop-up mechanism 30.

[0072] As can be seen from the above, the locking mechanism in the detergent box assembly 1 is coupled to the housing mechanism 10 and the cartridge mechanism 20 respectively. The locking mechanism includes a track 41, a track converter 42 and an actuating assembly 43. The actuating assembly 43 is coupled to the track converter 42. The actuating assembly 43 can drive the cartridge mechanism 20 to move relative to the housing mechanism 10 under the drive of the ejection mechanism 30. The track converter 42 includes a guiding portion 422 and a direction conversion portion 421. Since the direction conversion portion 421 can adjust the sliding position of the guiding portion 422 on the track 41, the guiding portion 422 can be adjusted to switch between the locking end 411 and the release end 412 of the track 41 along the first part 413 or the second part 414 of the loop. The stroke of the guiding portion 422 between the locking end 411 and the release end 412 is the actual moving distance of the detergent box assembly 1 relative to the housing mechanism 10. Therefore, the extra operations of the user when opening or closing the detergent box assembly 1 can be reduced.

[0073] In a specific implementation, in order to improve the orderly sliding of the guiding portion 422 of the track converter 42 between various parts of the track 41, the track 41 may further include a partition portion 419. The partition portion 419 is used to separate the first part 413 and the second part 414, so that when the guiding portion 422 moves in the track 41, the guiding portion 422 can only switch between the first part 413 and the second part 414 at the release end 412 or the locking end 411, thereby ensuring the orderly sliding of the track converter 42 in the track 41.

[0074] In a specific implementation, referring to Figure 7 , a cross-sectional view of an actuating assembly in an embodiment of the present invention is given; referring to Figure 8 , a schematic structural diagram of a pushing and blocking portion in an embodiment of the present invention is given; referring to Figure 9 , a schematic structural diagram of a cartridge mechanism in an embodiment of the present invention is given; referring to Figure 10 , a schematic structural diagram of a sliding member in an embodiment of the present invention is given; referring to Figure 11 , a cross-sectional view of a sliding member in an embodiment of the present invention is given. The structure of the actuating assembly will be described below in conjunction with Figure 2 , Figures 7 to 11 .

[0075] In a specific implementation, the actuating assembly 43 may include a sliding member 431 and a pushing and blocking portion 432. The sliding member 431 can be coupled to the ejection mechanism 30. The sliding member 431 includes a pushing rod 4311. The pushing and blocking portion 432 can be disposed on the cartridge mechanism 20. The pushing and blocking portion 432 cooperates with the pushing rod 4311, and the pushing and blocking portion 432 drives the cartridge mechanism 20 to move relative to the housing mechanism 10.

[0076] In a specific implementation, a first opening 12 may be provided on the housing mechanism 10. The first opening 12 is used to pass through the push rod 4311 and expose the push block portion 432, so that the push rod 4311 and the push block portion 432 can cooperate.

[0077] In an embodiment of the present invention, the push block portion 432 may be integrally formed on the cartridge mechanism 20. For example, the push block portion 432 may be integrally formed on a portion of the top of the cartridge mechanism 20 facing the housing mechanism 10. In an embodiment of the present invention, the push block portion 432 may also be connected to a portion of the top of the cartridge mechanism 20 facing the housing mechanism 10 by means of a snap or a fastener.

[0078] In a specific implementation, the push block portion 432 may include a first retaining rib 4321 and a second retaining rib 4322 which are arranged at intervals. The push rod 4311 is located between the first retaining rib 4321 and the second retaining rib 4322.

[0079] In some embodiments of the present invention, the first retaining rib 4321 and the second retaining rib 4322 are arranged along the insertion direction of the cartridge mechanism 20. The second retaining rib 4322 includes a first inclined surface 4323 and a second inclined surface 4324 which are oppositely arranged. Among them, the first inclined surface 4323 faces the removal direction of the cartridge mechanism 20, that is, the first inclined surface 4323 faces the first retaining rib 4321, and the second inclined surface 4324 faces the insertion direction of the cartridge mechanism 20. The slope of the first inclined surface 4323 is greater than the slope of the second inclined surface 4324. Since the slope of the first inclined surface 4323 is greater than the slope of the second inclined surface 4324, when the push block portion 432 is installed, the push rod 4311 can easily cross the second inclined surface 4324 to be installed between the first retaining rib 4321 and the second retaining rib 4322, and the larger slope of the first inclined surface 4323 can limit the push rod 4311 from crossing the first inclined surface 4323 when the cartridge mechanism 20 is inserted and removed.

[0080] When the cartridge mechanism 20 is inserted into the housing mechanism 10 along the insertion direction, that is, when the cartridge mechanism 20 is closed, the thrust is transmitted to the push rod 4311 through the first retaining rib 4321. At this time, the first retaining rib 4321 pushes the push rod 4311.

[0081] When the cartridge mechanism 20 is removed from the housing mechanism 10 along the removal direction, that is, when the cartridge mechanism 20 is opened, the push rod 4311 pushes the first retaining rib 4321. When the cartridge mechanism 20 is opened and closed, in order to prevent the push rod 4311 from slipping out of the first retaining rib 4321 and the second retaining rib 4322, the slope of the side surface of the first retaining rib 4321 facing the second retaining rib 4322 is relatively large. For example, the side surface of the first retaining rib 4321 facing the second retaining rib 4322 can be a vertical side surface, that is, it can be perpendicular to the cartridge mechanism 20.

[0082] Refer to Figure 12, shows a schematic structural diagram of an orbit converter in an embodiment of the present invention; Figure 13 shows a partial structural schematic diagram of an orbit converter in an embodiment of the present invention; Figure 14 shows a schematic structural diagram of a direction conversion part in an embodiment of the present invention. Figure 15 shows an installation schematic diagram of an orbit converter and a sliding member in an embodiment of the present invention; Figure 16 is Figure 15 a cross-sectional view from one perspective; Figure 17 is Figure 15 a cross-sectional view from another perspective; Figure 18 is Figure 15 a cross-sectional view from yet another perspective; Figure 19 is a partial structural cross-sectional view of a locking mechanism in an embodiment of the present invention. Figure 20 is a cross-sectional view of a detergent box assembly from another perspective in an embodiment of the present invention. The following will be combined with Figure 2 , Figures 7 to 20 , to describe the structures of the orbit converter and the locking mechanism.

[0083] In a specific implementation, the orbit converter 42 may further include an elastic abutting portion 423, and the elastic abutting portion 423 presses against the guiding portion 422 in the direction of the orbit 41.

[0084] In some embodiments of the present invention, referring to Figure 17 , the elastic abutting portion 423 abuts against one side surface 4317 of the sliding member 431 facing the cartridge mechanism 20.

[0085] In a specific implementation, one side surface 4317 of the sliding member 431 facing the cartridge mechanism 20 has a pair of third limiting portions 4312, and the orbit converter 42 is located in the accommodation space formed by the pair of third limiting portions 4312. The pair of third limiting portions 4312 can define the movement area of the elastic abutting portion 423 relative to the sliding member 431. The elastic abutting portion 423 can slide in the accommodation space formed by the third limiting portions 4312.

[0086] When the orbit converter 42 moves relative to the orbit 41, the top end of the elastic abutting portion 423 is always in contact with one side surface 4317 of the sliding member 431 facing the cartridge mechanism 20 and moves in the accommodation space formed by the pair of third limiting portions 4312. The elastic abutting portion 423 is subjected to the pressure of one side surface 4317 of the sliding member 431 facing the cartridge mechanism 20, so that the bottom end of the guiding portion 422 always closely adheres to the surface of the orbit 41 and moves, so as to ensure the reliability and accuracy of the switching of the guiding portion 422 between the first part 413 and the second part 414 of the orbit 41.

[0087] In a specific implementation, referring to Figures 15 to 18, the direction conversion part 421 is connected to the sliding part 431 and can rotate relative to the sliding part 431 around the first rotation axis A and the second rotation axis B, where the first rotation axis A is perpendicular to the second rotation axis B.

[0088] In some embodiments of the present invention, the first rotation axis A can be in the vertical direction, and the second rotation axis B can be in the horizontal direction.

[0089] In practical applications, affected by various factors such as the requirements of the actual application scenario and the actual shape of the direction conversion part 421, the actual shape and structure of the direction conversion part 421 can also have various different situations, as long as the first rotation axis A and the second rotation axis B are perpendicular, or the first rotation axis A and the second rotation axis B are not perpendicular, but it can enable the direction conversion part 421 to adjust the moving direction of the track converter in multiple directions.

[0090] For example, referring to Figure 14 , the direction conversion part 421 is generally in the shape of a hollow cylinder, and the axial direction of the hollow cylinder is the direction of the first rotation axis A. The radial direction of the hollow cylinder is the direction of the first rotation axis A. A connecting part 4213 is formed along the outer surface direction of the radial direction of the hollow cylinder, and the connecting part 4213 forms the second rotation axis B. The rotation positioning pin 425 inserted into the hollow part 4214 of the hollow cylinder can be used as the first rotation axis A, and the direction conversion part 421 can rotate around the rotation positioning pin 425. A first connection hole 4313 can be provided on the sliding part 431, and the rotation positioning pin 425 can pass through the first connection hole 4313. Through the cooperation of the rotation positioning pin 425 and the first connection hole 4313, the direction conversion part 421 is connected to the sliding part 431.

[0091] A second connection hole 424 is provided on the track converter 42 for connecting the direction conversion part 421. Specifically, the second connection hole 424 provided on the track converter 42 cooperates with the connecting part 4213 on the direction conversion part 421 to connect the direction conversion part 421 to the track converter 42.

[0092] Again, for example, the direction conversion part 421 is generally in the shape of a column, and connecting shafts extend along the axial direction at both ends of the direction conversion part 421, and the connecting shafts are used as the first rotation axis A. A connection hole is provided on the sliding part 431, and the connection hole cooperates with the connecting shaft to realize the connection between the direction conversion part 421 and the sliding part 431. Along the radial direction of the direction conversion part 421, a connecting part is formed on the outer surface direction, and the connecting part forms the second rotation axis B.

[0093] In practical applications, the direction conversion part 421 can also be of other structural shapes. For example, it can be a regular shape such as a cube shape or an irregular shape, as long as it can rotate around the first rotation axis and the second rotation axis, and the first rotation axis and the second rotation axis are perpendicular.

[0094] Reference Figure 23 shows a schematic structural diagram of an upper guide rail in an embodiment of the present invention; Figure 24 shows a partial structural schematic diagram of a detergent box assembly in an embodiment of the present invention. The structure of the housing mechanism 10 will be described below in conjunction with Figure 2 , Figure 3 , Figure 6 , Figure 20 , Figure 23 and Figure 24 .

[0095] In a specific implementation, the housing mechanism 10 may further include: an upper guide rail 13 and a lower guide rail 14. The upper guide rail 13 is detachably connected to the lower guide rail 14 and forms a second accommodation cavity 15. At least part of the ejection mechanism 30 and the locking mechanism are located in the second accommodation cavity 15. The track 41 is provided on the lower guide rail 14.

[0096] In an embodiment of the present invention, the lower guide rail 14 may have a second opening 141 for passing through the push rod 4311 so that the push rod 4311 can cooperate with the push block portion 432.

[0097] In a specific implementation, after the lower guide rail 14 is connected to the upper guide rail 13, a first guide rail is formed. The sliding member 431 is slidably connected to the first guide rail.

[0098] The first guide rail includes two parts, namely, the upper part 135 of the first guide rail located on the upper guide rail 13 and the lower part 147 of the first guide rail located on the lower guide rail 14. Part of the structure of the sliding member 431 is located between the upper part 135 of the first guide rail and the lower part 147 of the first guide rail.

[0099] In a specific implementation, the sliding member 431 may have a pair of connecting platforms 4314 connected to the first guide rail. When the sliding member 431 moves relative to the housing mechanism 10, the connecting platforms 4314 can move along the first guide rail.

[0100] In an embodiment of the present invention, a protrusion 4315 is provided on the connecting platform 4314. The protrusion 4315 contacts the first guide rail. Specifically, the protrusion 4315 is provided on at least one of the side surfaces of the connecting platform 4314 facing the upper guide rail 13 and the side surface facing the lower guide rail 14.

[0104] In an embodiment of the present invention, protruding portions 4315 may also be provided on the side wall of the connection platform 4314. The protruding portions 4315 on the side wall of the connection platform 4314 can define the position of the sliding member 431, prevent the sliding member 431 from wobbling when sliding relative to the housing mechanism 10 in the second accommodation cavity 15, and improve the stability of the sliding member 431 when sliding relative to the housing mechanism 10.

The second limiting walls 143 are located in the limiting groove.

[0108] In an embodiment of the present invention, the protruding portions 4315 provided on the side of the connection platform 4314 of the sliding member 431 face or abut against the second limiting walls 143.

[0109] In another embodiment of the present invention, the protruding portion 4315 provided on the side surface of the connection platform 4314 of the sliding member 431 faces or abuts against the third limiting wall 133.

[0113] Figure 21 For Figure 20 a partial schematic view at position P. Referring to Figure 25 , a structural schematic view of an upper cover plate in an embodiment of the present invention is given; referring to Figure 26 , a partial structural schematic view of an upper cover plate in an embodiment of the present invention is given. The structure of the housing mechanism 10 will be described below in conjunction with Figure 2 , Figure 20 , Figure 21 , Figure 25 and Figure 26 .

[0114] In a specific implementation, the housing mechanism 10 may further include a lower housing 16 and an upper cover plate 17 detachably connected to the lower housing 16. One end of the lower housing 16 has an opening 161, and the opening 161 is used to provide an entrance and exit for the cartridge mechanism 20.

[0115] In a specific implementation, after the upper cover plate 17 is connected to the lower housing 16, a second guide rail is formed, and the cartridge mechanism 20 moves relative to the housing mechanism 10 along the second guide rail.

[0116] Specifically, combined with Figure 21, a pair of fourth limiting walls 171 extend from the upper cover plate 17 towards the lower housing 16. The lower housing 16 has a third bending portion 162, and a fifth limiting wall 163 is formed in the portion of the third bending portion 162 in the vertical direction. The fifth limiting wall 163 cooperates with the fourth limiting wall 171 to cover the upper cover plate 17 on the lower housing 16.

[0117] Among them, the fifth limiting wall 163 can be located inside the fourth limiting wall 171 or outside the fourth limiting wall 171.

[0118] In a specific implementation, a pair of sixth limiting walls 172 extend from the upper cover plate 17 towards the lower housing 16. As Figure 21 shown, when the fifth limiting wall 163 is located inside the fourth limiting wall 171, the sixth limiting wall 172 is located inside the fourth limiting wall 171, and the sixth limiting wall 172 and the fourth limiting wall 171 form a limiting groove, and the fifth limiting wall 163 is located in the limiting groove. When the fifth limiting wall 163 is located outside the fourth limiting wall 171, the sixth limiting wall 172 is located outside the fourth limiting wall 171, and the sixth limiting wall 172 and the fourth limiting wall 171 form a limiting groove, and the fifth limiting wall 163 is located in the limiting groove.

[0119] In a specific implementation, the guide rail lower cover 14 can be integrally formed with the upper cover plate 17 or detachably connected to the upper cover plate 17.

[0120] In an embodiment of the present invention, when the guide rail lower cover 14 is integrally formed with the upper cover plate 17, a first opening 12 for exposing the pushing portion 432 and a second opening 141 for passing through the pushing rod 4311 are provided on the upper cover plate 17. The first opening 12 and the second opening 141 can be the same opening or different openings respectively.

[0121] In another embodiment of the present invention, when the guide rail lower cover 14 is detachably connected to the upper cover plate 17, a first opening 12 for exposing the pushing portion 432 is provided on the upper cover plate 17, and a second opening 141 for passing through the pushing rod 4311 is provided on the guide rail lower cover 14. The number of the second openings 141 can be related to the number of the pushing rods 4311.

[0122] For example, the number of the pushing rods 4311 is two and they are arranged oppositely. The number of the second openings 141 is two, and each pushing rod 4311 passes through the corresponding second opening 141 and the first opening 12 and then cooperates with the pushing portion 432. Under the action of the pop-up mechanism 30 and an external thrust, the pushing rod 4311 can move in the second opening 141 and the first opening 12.

[0123] The pop-up mechanism 30 can include an elastic stretching portion, one end of the elastic stretching portion is connected to the sliding member 431, and the other end of the elastic stretching portion is connected to the housing mechanism 10.

[0124] Combined with Figure 2 、 Figure 6 、 Figure 25 and Figure 26 When the lower rail cover 14 is detachably connected to the upper cover plate 17, a lower rail cover connection portion 145 is provided on the lower rail cover 14, and the lower rail cover connection portion 145 cooperates with the fastener 146 to connect the lower rail cover 14 to the upper cover plate 17.

[0125] In a specific implementation, the upper cover plate 17 may have a lower rail cover mating portion 18, and the lower rail cover mating portion 18 is used to cooperate with the lower rail cover connection portion 145 to connect the lower rail cover 14 to the upper cover plate 17.

[0126] Specifically, a lower rail cover fixing portion 181 is provided on the lower rail cover mating portion 18, and the lower rail cover fixing portion 181 and the lower rail cover connection portion 145 connect the lower rail cover 14 to the upper cover plate 17 through the fastener 146.

[0127] In an embodiment of the present invention, a first hook portion 4316 is provided on the sliding member 431, and one end of the elastic stretching portion is hooked to the first hook portion 4316.

[0128] In some embodiments of the invention, when the housing mechanism 10 includes an upper rail cover 13 and a lower rail cover 14, the other end of the elastic stretching portion may be connected to the lower rail cover 14. Specifically, a hook portion ‎144 is provided on the lower rail cover 14, and the other end of the elastic stretching portion is connected to the hook portion ‎144 on the lower rail cover 14.

[0129] In an embodiment of the present invention, the elastic stretching portion may be a spring or other components made of elastic materials.

[0130] In a specific implementation, in the scenarios of opening and closing the cartridge mechanism 20, when the user overcomes the elastic force of the elastic stretching portion and pushes the cartridge mechanism 20 in the pushing direction of the cartridge mechanism 20, the push block portion 432 connected to the cartridge mechanism 20 can drive the push rod 4311 of the sliding member 431 to move in the pushing direction of the cartridge mechanism 20.

[0131] In a specific implementation, in the scenario where the locking of the cartridge mechanism 20 is released and the cartridge mechanism 20 automatically pops out, under the action of the elastic stretching portion, the sliding member 431 moves in the moving-out direction of the cartridge mechanism 20, the push rod 4311 drives the push block portion 432, and the push block portion 432 drives the cartridge mechanism 20 to move in the moving-out direction of the cartridge mechanism 20.

[0132] Refer to Figure 27 which gives a schematic diagram of the sliding path of a track converter in a track in an embodiment of the present invention. Refer to Figures 3 to 6 、Figure 19 and Figure 27 , wherein, Figure 27 The arrow direction in Figure 27 indicates the sliding direction of the guiding part 422 within the track 41. In a specific implementation, the sliding path of the guiding part 422 on the track 41 is from the locking end 411 along the first part 413 to the release end 412, and from the release end 412 along the second part 414 to the locking end 411. One end of the second part 414 close to the locking end 411 has a first locking surface 416, and the first locking surface 416 can limit the guiding part 422 from moving along the second part 414 towards the release end 412, so that the cartridge mechanism 20 is in a locked state. The release end 412 has a second locking surface 418, and the second locking surface 418 can define the sliding of the guiding part 422 relative to the track 41, so that the cartridge mechanism 20 is in the maximum ejection displacement relative to the housing mechanism 10, so that the cartridge mechanism 20 remains stable after being opened.

[0133] In a specific implementation, the surface of one end of the second part 414 close to the locking end 411 sinks, and a first locking surface 416 is formed on the side wall of the sunken part. The surface of the first part 413 close to the locking end 411 is lower than the surface of the second part 414 close to the locking end 411.

[0134] In an embodiment of the present invention, the surface of the first part 413 close to the locking end 411 is lower than the surface of the sunken part of one end of the second part 414 close to the locking end 411.

[0135] In an embodiment of the present invention, the second locking surface 418 is located on the side wall of the release end 412 of the track 41.

[0136] In a specific implementation, the locking end 411 includes a first guiding surface 415, and the first guiding surface 415 is used to guide the guiding part 422 to change lanes from the second part 414 to the first part 413, and / or, the release end 412 has a second guiding surface 417, and the second guiding surface 417 is used to guide the guiding part 422 to change lanes from the first part 413 to the second part 414.

[0137] In a specific implementation, the first guiding surface 415 is located on the side wall of the locking end 411 of the track 41.

[0138] In a specific implementation, the surface of one end of the first part 413 close to the release end 412 sinks, and a second guiding surface 417 is formed on the side wall of the sunken part. The surface of the second part 414 close to the release end 412 is lower than the surface of the first part 413 close to the release end 412.

[0139] In some embodiments of the present invention, the height of the first part 413 of the track 41 gradually increases from the locking end 411 to the releasing end 412. At the releasing end 412, the surface of the first part 413 is higher than the surface of the second part 414. From the releasing end 412 to the locking end 411, the surface height of the second part 414 gradually increases. At the locking end 411, the surface of the second part 414 is higher than the surface of the first part 413. From the locking end 411 to the releasing end 412, the surface of the first part 413 of the track 41 gradually increases. At the releasing end 412, a height difference is formed between the surface of the first part 413 and the surface of the second part 414, and the surface of the first part 413 is higher than the surface of the second part 414.

[0140] Referring to Figure 28 , a schematic diagram of the relative position between the track converter and the track when the cartridge mechanism in the embodiment of the present invention is locked is given; Figure 29 A schematic diagram of the relative position between the track converter and the track when the cartridge mechanism in the embodiment of the present invention is unlocked is given. In order to improve the smoothness when the track converter 42 is unlocked, in the embodiment of the present invention, the side wall 4111 at the locking end 411 of the track 41 is obliquely arranged, and the angle between the side wall 4111 and the first part 413 is an acute angle, and the angle between the side wall 4111 and the second part 414 is an obtuse angle. Thus, when the cartridge mechanism 20 is locked, the guiding part 422 abuts against the first locking surface 416. When a thrust acts on the cartridge mechanism 20 to release the locking of the cartridge mechanism 20, it is convenient for the direction conversion part 421 to rotate around the first rotating shaft A, so as to facilitate the guiding part 422 to slide along the first guiding surface 415 formed by the side wall 4111. In addition, since the surface of the second part 414 is higher than the surface of the first part 413, at this time, the direction conversion part 421 rotates around the second rotating shaft B, so that the guiding part 422 falls from the second part 414 into the first part 413, that is, the switching from the second part 414 to the first part 413 is completed.

[0141] Referring to Figure 30 , a schematic diagram of the relative position between the track converter and the track when the cartridge mechanism in the embodiment of the present invention pops out is given; Figure 31The schematic diagram of the relative position between the track converter and the track when the cartridge mechanism in the embodiment of the present invention is in the open state is given. In order to improve the stability of the track converter 42 at the release end 412, in the embodiment of the present invention, the side wall 4121 at the release end 412 of the track 41 is obliquely arranged, and the included angle between the side wall 4121 and the first part 413 is an acute angle, and the included angle between the side wall 4121 and the second part 414 is an obtuse angle. Thus, when there is no external force, the guiding part 422 is stuck in the included angle area formed by the side wall 4121 and the first part 413 and will not switch from the first part 413 to the second part 414. When a thrust force acts on the cartridge mechanism 20, limited by the second guiding surface 417 formed by the sinking of the first part 413, the guiding part 422 cannot cross the second guiding surface 417 and enter the first part 413. The direction conversion part 421 rotates around the first rotating shaft A, and under the guidance of the second guiding surface 417, the direction conversion part 421 rotates around the second rotating shaft B again, so that the guiding part 422 switches from the first part 413 to the second part 414.

[0142] Referring to Figure 32 , a cross-sectional view of a detergent box assembly in another perspective in the embodiment of the present invention is given. Referring to Figure 2 , Figure 8 , Figure 9 , Figures 24 to 26 and Figure 32 , in a specific implementation, the detergent box assembly 1 may further include a damping mechanism 50. The damping mechanism 50 includes a damping rack 51 and a rotary damper. The damping rack 51 is connected to the cartridge mechanism 20 and is used to mesh with the gear 53 on the rotary damper. The rotary damper is connected to the housing mechanism 10. The housing mechanism 10 is provided with a damping fixing part 55. The damping fixing part 55 cooperates with the rotary fixing screw 54 to fix the rotary damper to the housing mechanism 10. A third opening 173 is provided on the housing mechanism 10, and the gear 53 passes through the third opening 173 to mesh with the damping rack 51.

[0143] The gear 53 on the rotary damper meshes with the damping rack 51. When the cartridge mechanism 20 is ejected, the damping rack 51 drives the gear 53 on the rotary damper to rotate, generating a damping force inside the rotary damper, thereby producing a damping effect and realizing the smooth ejection of the cartridge mechanism 20. In the embodiment of the present invention, the characteristic of the rotary damper may be that the damping force is proportional to the rotation speed, that is, the faster the rotation speed of the gear 53, the greater the damping force generated, and the slower the rotation speed of the gear 53, the smaller the damping force generated.

[0144] In the embodiment of the present invention, the damping rack 51 may be connected to the first rib 4321.

[0145] Referring to Figure 2 , Figure 9 , Figure 20 ,Figure 21 In a specific implementation, the cartridge mechanism 20 includes a cartridge body 21 and a cartridge cover 22. The cartridge cover 22 is detachably connected to the cartridge body 21 and forms a third accommodation cavity 23 for containing the laundry treatment agent.

[0146] In a specific implementation, a feeding port 24 for dispensing the laundry treatment agent is provided on the cartridge cover 22.

[0147] In an embodiment of the present invention, a first discharge port may be provided on the cartridge body 21 for providing an outlet for the laundry treatment agent. Since the cartridge mechanism 20 is located inside the housing mechanism 10, in order to facilitate the dispensing of the laundry treatment agent, a second discharge port may be provided on the lower housing of the housing mechanism 10 to dispense the laundry treatment agent into the laundry equipment.

[0148] In a specific implementation, the pushing and blocking portion 432 may be provided on the cartridge cover 22 of the detergent cartridge.

[0149] In a specific implementation, in order to facilitate the operation of the detergent cartridge assembly 1, the detergent cartridge assembly 1 may further include a handle assembly 60. The handle assembly 60 includes a handle decorative member, a handle, and a distance adjustment portion. Among them, the distance adjustment portion is located between the handle decorative member and the handle and is respectively connected to the handle decorative member and the handle. When the handle decorative member is pressed, the relative distance between the handle decorative member and the handle is reduced; the handle is connected to the cartridge mechanism 20.

[0150] In a specific implementation, referring to Figure 2 , a handle connection portion 64 may be provided on the cartridge mechanism 20. The handle connection portion 64 is used to connect the handle assembly 60.

[0151] To facilitate those skilled in the art to better understand and implement the embodiments of the present invention, the working principle of the detergent cartridge assembly 1 will be described below with reference to the attached Figures 1 to 33 drawings.

[0152] Referring to Figure 20 and Figure 32 , when the slider 431 moves, it will drive the guiding portion 422 of the track converter 42 to move within the track 41 of the lower rail cover 14. Referring to Figure 17 and Figure 32, when the rail converter 42 moves, the top end of the elastic abutting portion 423 of the rail converter 42 will always contact the side surface 4317 of the slider 431 facing the cartridge mechanism 20. Therefore, the elastic abutting portion 423 is subjected to a compressive force, so that the bottom end of the guiding portion 422 always moves closely against the surface of the rail 41. Under the action of the elastic abutting portion 423, no matter which part of the rail 41 the guiding portion 422 is located in, the bottom end of the guiding portion 422 always moves closely against the surface of the rail 41. The function of the elastic abutting portion 423 is like a spring, applying an elastic force to the bottom end of the guiding portion 422 to improve the reliability and accuracy of the direction conversion portion 421 switching between various parts of the rail 41.

[0153] Referring to Figure 4 , the rail 41 may include a locking end 411, a release end 412, and a first portion 413 and a second portion 414 respectively connected to the locking end 411 and the release end 412. The rail 41 is a loop. There are height differences between the locking end 411, the release end 412, the first portion 413 and the second portion 414, and there are also height differences between the first portion 413 and the second portion 414 itself. By setting reasonable height differences, the rail converter 42 can slide in the rail 41 in a set direction, avoiding the rail converter 42 sliding in the rail 41 in other directions except the set direction.

[0154] Referring to Figure 31 , the principle of locking in the closed state of the cartridge mechanism 20 is as follows: the elastic stretching portion is stretched to generate a pulling force in the moving-out direction of the cartridge mechanism 20. This force is applied to the slider 431 and finally transmitted to the guiding portion 422 of the rail converter 42, and pulls the rail converter 42 and the slider 431 to move. However, a first locking surface 416 is formed by the sinking of the surface of the end of the second portion 414 close to the locking end 411, so that the guiding portion 422 cannot slide along the second portion 414 from the locking end 411 towards the release end 412, but stays at the first locking surface 416. This is the locking position in the closed state of the cartridge mechanism 20.

[0155] Referring to Figure 4 , Figure 28 and Figure 29 , the unlocking principle of the cartridge mechanism 20 will be described. In the closed state of the cartridge mechanism 20, when the cartridge mechanism 20 is pushed in the pushing direction towards the cartridge mechanism 20, the thrust is transmitted from the first rib 4321 of the cartridge cover 22 to the push rod 4311 of the slider 431 and drives the rail converter 42 to move in the pushing direction towards the cartridge mechanism 20. When the guiding portion 422 of the rail converter 42 contacts the first guiding surface 415 (such as Figure 4 ), combined with Figure 17 and 18, the guiding part 422 will move along the first guiding surface 415, causing the track converter 42 to rotate by a certain angle around the first rotating shaft A. At the same time, under the action of the elastic abutting part 423, when the bottom end of the guiding part 422 leaves the surface of the second part 414 located at the locking end 411, due to the height difference between the second part 414 and the first part 413, the track converter 42 rotates by a certain angle around the second rotating shaft B, causing the guiding part 422 to fall into the first part 413 and closely adhere to the surface of the first part 413. Thus, the switching of the guiding part 422 from the second part 414 to the first part 413 is completed, realizing the transition of the cartridge mechanism 20 from the locked state to the unlocked state.

[0156] Refer to Figure 30 and 31 , the working principle of the automatic ejection and automatic locking after ejection of the cartridge mechanism 20 will be described. After the cartridge mechanism 20 is unlocked in the closed state, under the action of the pulling force of the elastic stretching part, the cartridge mechanism 20 is automatically ejected, and the sliding part 431 drives the guiding part 422 to move forward closely along the first part 413 of the track 41. When the guiding part 422 reaches the release end 412, since at the release end 412, the surface of the first part 413 sinks, refer to Figure 33 and in combination with Figure 17 and Figure 18 , at this time, under the action of the elastic abutting part 423, the track converter 42 rotates by a certain angle around the second rotating shaft B, causing the guiding part 422 to enter the sunken part 4131 of the surface from the first part 413. The guiding part 422 is blocked by the second locking surface 418, and the guiding part 422 cannot continue to move in the moving direction of the cartridge mechanism 20 under the pulling of the elastic stretching part, thereby realizing the locking after the automatic ejection of the cartridge mechanism 20 (as shown in Figure 31 ).

[0157] Refer to Figure 31, the working principle of the cartridge mechanism 20 from the ejected state to the locked state will be described. After the cartridge mechanism 20 is ejected and locked, when it is necessary to close the cartridge mechanism 20, that is, when it is necessary to push the cartridge mechanism 20 into the housing mechanism 10, the cartridge mechanism 20 is pushed in the pushing direction of the cartridge mechanism 20. The first rib 4321 provided on the lid 22 drives the push rod 4311 of the sliding member 431, so that the sliding member 431 moves in the pushing direction of the cartridge mechanism 20. Since the first part 413 sinks on the surface of the release end 412, a height difference is formed. Under the abutment of the elastic abutting portion 423, the guiding portion 422 cannot cross the second guiding surface 417 formed by the sinking of the first part 413 on the surface of the release end 412. When the guiding portion 422 contacts the second guiding surface 417, the track converter 42 rotates a certain angle around the first rotating shaft A. At the same time, under the action of the elastic abutting portion 423, the guiding portion 422 is guided by the second guiding surface 417, and the bottom end of the guiding portion 422 disengages from the surface of the first part 413. At the release end 412, there is a height difference between the first part 413 and the second part 414. The track converter 42 rotates a certain angle around the second rotating shaft B, so that the guiding portion 422 falls into the second part 414, so as to realize the switching of the guiding portion 422 from the first part 413 to the second part 414. After the guiding portion 422 is switched to the second part 414, under the action of the elastic abutting portion 423 and the external thrust, the guiding portion 422 moves along the surface of the second part 414 in the pushing direction of the cartridge mechanism 20, that is, towards the locking end 411. Thereafter, the track converter 42 continues to move in the pushing direction of the cartridge mechanism 20 in the second part 414 until the guiding portion 422 reaches the locking end 411. Since at the locking end 411, the surface of the second part 414 sinks to form a first locking surface 416, after the bottom end of the guiding portion 422 enters the sunken part of the second part 414, at this time, the pushing of the cartridge mechanism 20 is stopped, and the guiding portion 422 is blocked by the first locking surface 416 and cannot move in the pulling direction of the elastic stretching portion in the moving-out direction of the cartridge mechanism 20. Thus, the process of closing and locking the cartridge mechanism 20 is completed.
