[0033] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0034] Reference below Figure 1-Figure 8 A laundry treatment agent box assembly 100 according to an embodiment of a first aspect of the present invention is described.

[0035] like Figure 1 As shown, the laundry treatment agent box assembly 100 according to the first embodiment of the present invention includes: a box body 1, a sealing cover 2 and a bracket 3.

[0036] Specifically, Figure 2 and Figure 8 As shown, a housing chamber 11 is formed in the box body 1, and an injection port 12 connected to the housing chamber 11 is formed on the box body 1; wherein, the housing chamber 11 in the box body 1 may include a detergent chamber 11a and / or a softener chamber 11b, and the injection port 12 on the box body 1 may include a detergent injection port 12a and / or a softener injection port 12b, the detergent injection port 12a may be connected to the detergent chamber 11a, and the user may inject detergent for washing clothes into the detergent chamber 11a through the detergent injection port 12a, and the softener injection port 12b may be connected to the softener chamber 11b, and the user may inject softener for washing clothes into the softener chamber 11b through the softener injection port 12b. Of course, the present invention is not limited to this, and housing chambers 11 with other functional purposes may also be provided in the box body 1, and each housing chamber 11 may be provided with an injection port 12 for injecting a corresponding solution or washing supplies.

[0037] The sealing cover 2 is sealed to the periphery of the injection port 12, and the sealing cover 2 is used to open and close the injection port 12. When the user opens the sealing cover 2, the user can inject the required washing products (such as detergent and / or softener) into the accommodating cavity 11 through the injection port 12. When the user closes the sealing cover 2, the sealing cover 2 can cover and seal the injection port 12 to prevent foreign matter and impurities from entering the accommodating cavity 11.

[0038] Among them, a sealing member (such as a sealing ring) can be provided between the sealing cover 2 and the periphery of the injection port 12 to achieve a sealed connection, and a sealing structure that cooperates with each other can also be provided on the periphery of the sealing cover 2 and the injection port 12 to achieve a sealed connection between the two. For example, the sealing cover 2 and the periphery of the injection port 12 can be connected by a thread, so that the thread structure can not only achieve the connection between the sealing cover 2 and the periphery of the injection port 12, but also achieve the sealing between the two. Of course, an elastic member can also be provided on the sealing cover 2, and the elastic member and the peripheral wall of the injection port 12 have an interference fit, which can also achieve the sealing and connection between the sealing cover 2 and the periphery of the injection port 12.

[0039] Furthermore, if Figure 2 As shown, the sealing cover 2 is rotatably disposed on the bracket 3, that is, the sealing cover 2 can rotate relative to the bracket 3, so that when the sealing cover 2 needs to open the injection port 12, the sealing cover 2 and the periphery of the injection port 12 can be separated by screwing the sealing cover 2; when the sealing cover 2 needs to close the injection port 12, the sealing cover 2 and the periphery of the injection port 12 can be sealed and connected by screwing the sealing cover 2.

[0040] like Figure 1 and Figure 5 As shown, the bracket 3 is in the first position (eg Figure 1 ) and a second position (eg, Figure 5 That is, the bracket 3 is provided on the box body 1, and the bracket 3 can rotate relative to the box body 1. During the rotation, the bracket 3 can rotate to the first position or the second position.

[0041] When the bracket 3 is in the first position, the sealing cover 2 is located at the injection port 12, and the sealing cover 2 is adapted to be sealed and connected to the periphery of the injection port 12. For example, when the bracket 3 is in the first position, the sealing cover 2 can be rotated to connect or disconnect the periphery of the injection port 12. When the bracket 3 is in the second position, the sealing cover 2 is spaced apart from the injection port 12.

[0042] Reference Figure 5When the injection port 12 needs to be opened, the sealing cover 2 can be screwed to separate the sealing cover 2 from the edge of the injection port 12. At this time, the bracket 3 can be rotated to rotate the bracket 3 from the first position to the second position. The sealing cover 2 and the injection port 12 are spaced apart by a predetermined distance, so that the injection port 12 can be fully opened. The user can now inject the required washing products into the accommodating chamber 11 through the injection port 12. After the user has finished injecting, the bracket 3 can be rotated to rotate the bracket 3 from the second position to the first position, and then the sealing cover 2 can be screwed to seal the sealing cover 2 and the edge of the injection port 12.

[0043] In this embodiment, a rotatable bracket 3 is provided to support and fix the sealing cover 2. When the sealing cover 2 is needed, the bracket 3 can be rotated to move the sealing cover 2 to the position of the injection port 12. When the sealing cover 2 is not needed, the bracket 3 can be rotated again to move the sealing cover 2 away from the injection port 12. In this way, the sealing cover 2 can be always fixed on the box body 1 by the bracket 3, and will not be completely separated from the box body 1, thereby avoiding the problem of the sealing cover 2 being lost. Moreover, since the sealing cover 2 does not need to be completely removed from the box body 1 and can be supported on the bracket 3, the user does not need to place the sealing cover 2 on the surface of the box body 1 or the surface of the top cover of the washing machine, thereby avoiding the detergent on the sealing cover 2 from sticking to the surface of the box body 1 or the washing machine, and avoiding the box body 1 or the top cover from being soiled.

[0044] In short, according to the laundry treatment agent box assembly 100 of the embodiment of the present invention, by providing a bracket 3 rotatable relative to the box body 1 and rotatably arranging the sealing cover 2 on the bracket 3, it is possible to avoid the sealing cover 2 from being lost and to avoid the detergent on the sealing cover 2 from sticking to the detergent box body 1 or the top cover of the washing machine.

[0045] In one embodiment of the present invention, referring to Figure 1 and Figure 2 When the bracket 3 is in the first position, the sealing cover 2 can rotate between the locking position and the unlocking position relative to the injection port 12. When the sealing cover 2 is in the locking position, the sealing cover 2 is locked to the periphery of the injection port 12. When the sealing cover 2 is in the unlocking position, the sealing cover 2 is unlocked from the periphery of the injection port 12. That is to say, when the bracket 3 is rotated to make the sealing cover 2 located at the injection port 12, the sealing cover 2 can rotate relative to the injection port 12. Specifically, the sealing cover 2 can be rotated to the locking position where it is locked with the periphery of the injection port 12, and the sealing cover 2 can also be rotated to the unlocking position where it is out of locking with the periphery of the injection port 12. Therefore, the sealing cover 2 can be unlocked and locked with the periphery of the injection port 12 by rotating the sealing cover 2, which is simple to operate and convenient to lock and unlock.

[0046] In a specific example of the present invention, referring to Figure 2The circumferential wall of the injection port 12 may be formed with an avoidance groove 13 and a limiting groove 14, both of which are recessed outwardly along the radial direction of the injection port 12, and the avoidance groove 13 and the limiting groove 14 are connected in the circumferential direction of the injection port 12. Further, in the axial direction of the injection port 12, the avoidance groove 13 may pass through the inlet end edge of the injection port 12 (for example, Figure 2 The limiting groove 14 is located at one side of the inlet end of the injection port 12 (for example, Figure 2 The upper side of the limiting groove 14 shown in FIG. 1 is formed with a raised stopper 15. The avoidance groove 13, the limiting groove 14 and the stopper 15 are used to cooperate with the sealing cover 2 to lock and unlock the sealing cover 2.

[0047] Furthermore, the sealing cover 2 may be formed with a locking protrusion 22 on its periphery, and the locking protrusion 22 extends radially outward from the sealing cover 2. The locking protrusion 22 is adapted to cooperate with the peripheral wall of the injection port 12 to lock the sealing cover 2 at the injection port 12 position.

[0048] Specifically, when the sealing cover 2 is in the unlocked position, the locking protrusion 22 is adapted to be inserted into the avoidance groove 13. For example, the locking protrusion 22 may be located in the avoidance groove 13, or the locking protrusion 22 may be aligned with the avoidance groove 13 in the axial direction of the injection port 12 (for example, Figure 2 When the user pushes the sealing cover 2 in the axial direction of the injection port 12, the locking protrusion 22 can be inserted into the avoidance groove 13. When the sealing cover 2 is in the locked position, the locking protrusion 22 is located in the limiting groove 14, and the locking protrusion 22 abuts against the inner side surface of the stop block 15 in the axial direction of the injection port 12 (for example, Figure 2 As shown in FIG. 1 , the stopper 15 is a surface of the stopper 15 facing the accommodating cavity 11. Thus, the stopper 15 can block the locking protrusion 22 in the axial direction of the injection port, and the locking protrusion 22 is limited to the side of the stopper 15 facing the accommodating cavity 11, thereby limiting the displacement of the sealing cover 2 in the axial direction of the injection port 12, preventing the sealing cover 2 from exiting the injection port 12 along the axial direction, and achieving the effect of locking the sealing cover 2.

[0049] In this way, when the user needs to close the injection port 12, the bracket 3 can be rotated first so that the sealing cover 2 is located at the injection port 12. At this time, the sealing cover 2 can be rotated so that the locking protrusion 22 on the sealing cover 2 is opposite to the avoidance groove 13 on the peripheral wall of the injection port 12 in the axial direction of the injection port 12. Then, the user can push the sealing cover 2 axially along the injection port 12 so that the locking protrusion 22 is inserted into the avoidance groove 13, and continue to press the sealing cover 2 so that the locking protrusion 22 moves along the axial direction of the injection port 12 to the lower side of the stop block 15. At this time, the locking protrusion 22 is still located in the avoidance groove 13, and then the sealing cover 2 is rotated in the direction from the avoidance groove 13 to the limiting groove 14, and the locking protrusion 22 is rotated to the limiting groove 14 and located directly below the stop block 15. In this way, the sealing cover 2 can be locked at the injection port 12.

[0050] When the user needs to open the injection port 12, the user rotates the sealing cover 2 along the direction from the limiting groove 14 toward the avoiding groove 13 to move the locking protrusion 22 from the limiting groove 14 to the avoiding groove 13, and then pulls the sealing cover 2 along the axial direction of the injection port 12, or rotates the bracket 3 to make the locking protrusion 22 withdraw from the avoiding groove 13, and continues to pull the sealing cover 2 or rotate the bracket 3 to completely separate the sealing cover 2 from the injection port 12, thereby opening the injection port 12.

[0051] In a specific example, if Figure 2 and Figure 4 As shown, the locking protrusion 22 may include multiple locking protrusions 22, and the multiple locking protrusions 22 may be arranged at intervals in the circumferential direction of the sealing cover 2. Furthermore, multiple matching locking structures are formed on the peripheral wall of the injection port 12, and the multiple matching locking structures correspond to the multiple locking protrusions 22 one by one. Each matching locking structure includes an avoidance groove 13, a limiting groove 14 and a stop block 15. Therefore, when the sealing cover 2 is locked at the injection port 12 position, the uniformity of the force applied to the sealing cover 2 in the circumferential direction can be improved, and the reliability of locking can be ensured.

[0052] For example, there may be two locking protrusions 22, which are symmetrically arranged on both sides of the sealing cover 2 in the radial direction, and two matching locking structures consisting of an avoidance groove 13, a limiting groove 14 and a stopper 15 are formed on the peripheral wall of the injection port 12, and the two matching locking structures are rotationally symmetrical about the central axis of the injection port 12. Thus, the structure is simple and the force is evenly applied.

[0053] In some embodiments, Figure 4As shown, a groove 23 that is concave downward is formed on the upper surface of the sealing cover 2, and the outer contour of the groove 23 can be formed in a circular shape. A rib 24 that protrudes upward is formed on the bottom wall of the groove 23. The rib 24 extends in the radial direction of the groove 23, and the upper surface of the rib 24 is substantially flush with the upper end of the groove 23. When the sealing cover 2 needs to be rotated to lock and unlock the sealing cover 2, the user can manually move the rib 24 in the circumferential direction to rotate the sealing cover 2, thereby realizing unlocking or locking the sealing cover 2. In this way, the user can operate conveniently.

[0054] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, one end of the bracket 3 (eg Figure 3 The right end of the first bracket 3a or the left end of the second bracket 3b shown in FIG. 3 may be formed as a pivot portion 31, and the other end of the bracket 3 (eg Figure 3 The left end of the first bracket 3a or the right end of the second bracket 3b shown in the figure can be formed into a holding portion 32, the pivoting portion 31 is rotatably connected to the box body 1, and the sealing cover 2 is connected to the holding portion 32. In this way, the rotation axis of the bracket 3 can be separated from the sealing cover 2 to prevent the sealing cover 2 from interfering with the rotation of the bracket 3. At the same time, when the sealing cover 2 is opened and the bracket 3 is rotated, the distance between the sealing cover 2 and the injection port 12 can be increased to prevent the sealing cover 2 from blocking the injection port 12, making it more convenient to inject detergent.

[0055] like Figure 4 As shown, the bracket 3 includes two brackets, namely a first bracket 3a and a second bracket 3b. The first bracket 3a can extend in the left-right direction. A clamping portion 32 is formed at the left end of the first bracket 3a. The clamping portion 32 is used to clamp the sealing cover 2. A pivot portion 31 can be formed at the right end of the first bracket 3a. The pivot portion 31 extends perpendicular to the left-right direction in a horizontal plane. The pivot portion 31 is formed in a hollow sleeve shape, and an opening is formed on the pivot portion 31 that passes through the pivot portion 31 along the axial direction of the pivot portion 31. The opening passes through the pivot portion 31 along the radial direction of the pivot portion 31, that is, the pivot portion 31 is formed in a C-shaped cross section perpendicular to its axial direction. The second pivot portion of the second bracket 3b is formed with a support shaft. When the first bracket is assembled with the second bracket, the pivot portion 31 of the first bracket 3a can be conveniently sleeved on the support shaft 34 of the second bracket 3b to achieve relative rotation relative to the support shaft 34.

[0056] In one embodiment, Figure 4 As shown, the bracket 3 may further include a connecting plate portion 33, which may be connected between the pivot portion 31 and the clamping portion 32, the pivot portion 31 having a pivot axis, the connecting plate portion 33 being formed in a flat plate shape extending parallel to the pivot axis, and the clamping portion 32 being connected to the other end of the connecting plate portion 33 (e.g. Figure 4The left end of the connecting plate portion 33 of the first bracket 3a shown in FIG. 3a extends in a direction away from the pivot axis. Thus, by providing the connecting plate portion 33, the distance between the pivot portion 31 and the clamping portion 32 can be further increased, so that the sealing cover 2 is prevented from interfering with the rotation of the pivot portion 31, and the sealing cover 2 is prevented from blocking the injection port 12 after the injection port 12 is opened, so that the detergent can be injected more conveniently.

[0057] In one embodiment, referring to Figure 4 As shown, the clamping portion 32 can extend along the circumference of the sealing cover 2, and the inner side of the clamping portion 32 defines a matching groove 321, and the sealing cover 2 is rotatably arranged in the matching groove 321. As a result, the structure is simple, and it is convenient for the bracket 3 to be sleeved with the sealing cover 2 to achieve rotatable connection with the sealing cover 2. For example, the clamping portion 32 can be formed into a ring extending along the circumference of the sealing cover 2, the sealing cover 2 is sleeved on the radial inner side of the clamping portion 32, and the sealing cover 2 can rotate relative to the clamping portion 32 in the clamping portion 32.

[0058] In one example, if Figure 4 As shown, a clamping groove 21 is formed on the outer peripheral wall of the sealing cover 2, and the clamping groove 21 extends in a ring shape along the circumference of the sealing cover 2. The clamping groove 21 is formed by the outer peripheral wall of the sealing cover 2 being recessed radially inward. The clamping portion 32 can be formed as a clamping ring with a notch 322, and the clamping ring is clamped into the clamping groove 21, and the clamping ring can slide relatively in the clamping groove 21. Therefore, through the cooperation of the clamping groove 21 and the clamping ring, the sealing cover 2 can be fixed on the bracket 3, and the sealing cover 2 can also rotate relative to the clamping ring.

[0059] Among them, preferably, the holding portion 32 can extend along an arc line concentric with the central axis of the sealing cover 2, and the position of the notch 322 on the retaining ring is located at the end of the retaining portion 32 that is away from the rotation axis of the bracket 3. In this way, the sealing cover 2 can be easily installed from the position of the notch 322 into the inner side of the retaining ring serving as the retaining portion 32, avoiding interference between the sealing cover 2 and the pivot portion 31 and the connecting plate portion 33 of the bracket 3, thereby facilitating assembly and improving assembly efficiency.

[0060] Of course, the present invention is not limited thereto, and the contour shape of the clamping ring formed by the clamping portion 32 may also be formed into a U-shape.

[0061] Optionally, the holding portions 32 are symmetrically arranged about a center line perpendicular to the width direction of the bracket 3. Thus, the structure is simpler, the processing and manufacturing of the bracket 3 are convenient, and the assembly and disassembly of the sealing cover are convenient.

[0062] In some embodiments, the sealing cover 2 is disposed in the length direction of the bracket 3 (eg Figure 4Thus, when the bracket 3 is rotated to the first position, the position of the sealing cover 2 can be adjusted so that the sealing cover 2 can be directly opposite to the injection port 12, ensuring that the sealing cover 2 can be aligned with the injection port 12 to achieve sealing and connection.

[0063] In some embodiments, reference Figure 8 When the snap ring is inserted into the slot 21, the inner end surface of the snap ring and the bottom wall of the slot 21 are clearance-matched in the radial direction of the injection port 12. Thus, the contact area between the snap ring and the slot 21 can be reduced, the friction force can be reduced, and the sealing cover 2 can be ensured to rotate smoothly on the snap ring.

[0064] Furthermore, the bottom wall of the clamping groove 21 in the radial direction of the injection port 12 is formed as an inclined surface extending obliquely in the axial direction of the sealing cover 2, and a part of the inner end surface of the clamping ring in the radial direction is formed as an obliquely extending guide surface, the guide surface is substantially parallel to the bottom wall of the clamping groove 21, and the other part of the inner end surface of the clamping ring in the radial direction is formed as a cylindrical surface extending along the axis of the clamping ring. Thus, the guiding surface of the clamping ring can play a guiding role when assembling the sealing cover 2, thereby improving the assembly effect. At the same time, the other part of the end surface of the clamping ring is formed as a cylindrical surface, which can be spaced apart from the bottom wall of the clamping groove 21 in the radial direction, thereby reducing the contact area, reducing the friction force, and ensuring that the sealing cover 2 can rotate smoothly.

[0065] According to some embodiments of the present invention, Figure 1 and Figure 2 As shown, the accommodating chamber 11 may include a detergent chamber 11a and a softener chamber 11b, the detergent chamber 11a and the softener chamber 11b are arranged at intervals, and the injection port 12, the sealing cover 2 and the bracket 3 each include two corresponding to the detergent chamber 11a and the softener chamber 11b.

[0066] Specifically, Figure 2As shown, two accommodating chambers 11 are formed in the box body 1, a detergent chamber 11a for storing detergent and a softener chamber 11b for storing softener. Two injection ports 12 are formed on the box body 1. The two injection ports 12 include a detergent injection port 12a and a softener injection port 12b. The detergent injection port 12a and the softener injection port 12b are arranged separately. The detergent injection port 12a is connected with the detergent chamber 11a for storing detergent in the detergent chamber 11a. The softener injection port 12b is connected with the softener chamber 11b for injecting softener into the softener chamber 11b. The sealing cover 2 includes a detergent cover 2a and a softener cover 2b. The detergent cover 2a is used to open and close the detergent injection port 12a, and the softener cover 2b is used to open and close the softener injection port 12b. The bracket 3 includes a first bracket 3a and a second bracket 3b, which are rotatably connected to the box body 1, the detergent cover 2a is rotatably disposed on the first bracket 3a, and the softener cover 2b is rotatably disposed on the second bracket 3b.

[0067] In this embodiment, by arranging both the detergent cover 2a and the softener cover 2b on the bracket 3, not only the problem of the detergent cover 2a and the softener cover 2b being lost can be avoided, but also the problem of the detergent cover 2a and the softener cover 2b being confused with each other can be avoided. In addition, the detergent and softener on the detergent cover 2a and the softener cover 2b can be prevented from sticking to the box body 1 or the top cover of the washing machine.

[0068] In a specific embodiment, Figure 5 and Figure 6 As shown, the two brackets 3 are respectively a first bracket 3a and a second bracket 3b, the first bracket includes a first pivot portion 31a, a first clamping portion 32a and a first connecting plate portion 33a, the first pivot portion 31a and the first clamping portion 32a are respectively connected to the two ends of the first connecting plate portion 33a (for example Figure 2 The second bracket includes a second pivot portion 31b, a second clamping portion 32b and a second connecting plate portion 33b, and the second pivot portion 31b and the second clamping portion 32b are respectively connected to the two ends of the second connecting plate portion 33b (for example Figure 2 The first pivoting portion 31a is rotatably fixed to the second pivoting portion 31b, and the two sealing covers are respectively clamped on the first clamping portion 32a and the second clamping portion 32b.

[0069] Here, it should be noted that the first pivoting portion 31a of the first bracket and the second pivoting portion 31b of the second bracket are not directly fixed to the box body 1. In this embodiment, when the detergent cover 2a is covered on the detergent injection port, the first bracket is indirectly fixed to the box body 1 through the detergent cover 2a, when the softener cover 2b is covered on the softener injection port, the second bracket is indirectly fixed to the box body 1 through the softener cover 2b, and when the detergent cover 2a and the softener cover 2b are simultaneously covered on the detergent injection port and the softener injection port, the first bracket and the second bracket are respectively fixed to the box body 1 through the corresponding detergent cover 2a and the softener cover 2b, and the first pivoting portion 31a of the first bracket and the second pivoting portion 31b of the second bracket are rotatably connected.

[0070] At this time, when only the detergent cover 2a is rotated to open, the detergent cover 2a is first screwed to the unlocked position, the first bracket is rotated, the second bracket is fixed, and the first bracket rotates around the pivot connected to the second bracket. When only the softener cover 2b is rotated to open, the softener cover 2b is first screwed to the unlocked position, and then the second bracket is rotated. At this time, the first bracket is fixed, and the second bracket rotates around the pivot connected to the first bracket. In addition, when the detergent cover 2a and the softener cover 2b are both screwed away from the detergent injection port and the softener injection port, at this time, the first bracket, the second bracket, the detergent cover 2a and the softener cover 2b can be separated from the box body 1 as a whole, that is, they can be completely separated from the box body 1.

[0071] Furthermore, if Figure 3 As shown, an axial hole 35 is formed on one of the first pivot part 31a and the second pivot part 31b, and a support shaft 34 is formed on the other of the first pivot part 31a and the second pivot part 31b. The support shaft 34 is rotatably disposed in the axial hole 35, thereby realizing a relatively rotatable connection between the first pivot part 31a and the second pivot part 31b.

[0072] Preferably, in one example, the first pivot portion 31a can be formed into a hollow sleeve shape with an opening, and an axial hole 35 is defined on the inner side of the hollow sleeve of the first pivot portion 31a, and the opening penetrates the first pivot portion 31a along the axial direction and radial direction of the first pivot axis. In this way, during the assembly of the first bracket and the second bracket, the support shaft 34 can be inserted into the axial hole 35 from the opening position along the radial direction, thereby simplifying the operation and facilitating the assembly.

[0073] For example Figure 3 As shown, the first bracket may include a first bracket in the length direction (eg Figure 3The first pivot portion 31a, the first connecting plate portion 33a and the first clamping portion 32a are sequentially connected in a left-right direction as shown in the figure, wherein the first pivot portion 31a has a pivot axis, and the first bracket is rotatable around the pivot axis of the first pivot portion 31a. Specifically, the first pivot portion 31a extends perpendicularly to the left-right direction in a horizontal plane, the first pivot portion 31a is formed into a hollow sleeve shape, and an opening is formed on the first pivot portion 31a that passes through the first pivot portion 31a in the axial direction, and the opening passes through the first pivot portion 31a in the radial direction of the first pivot portion 31a. At this time, the first pivot portion 31a is formed into a C-shape in a cross section perpendicular to its axial direction, and an axial hole 35 is defined on the inner side.

[0074] Further, the first connecting plate portion 33a is formed into a flat plate shape extending along a pivot axis parallel to the first pivot axis, and the first clamping portion 32a is connected to the other end of the first connecting plate portion 33a opposite to the first pivot portion 31a (for example Figure 3 The first clamping portion 32a extends along an arc line at the left end of the first connecting portion, and a matching groove 321 is defined inside the arc of the first clamping portion 32a. A notch 322 communicating with the matching groove 321 is formed between the two ends of the first clamping portion 32a in the extending direction, that is, the first clamping portion 32a is formed as a clamping ring with a notch 322.

[0075] The second bracket may include a second bracket in the length direction (eg Figure 3 The second pivot portion 31b, the second connecting plate portion 33b and the second clamping portion 32b are sequentially connected (in the left and right direction shown in the figure), wherein the second pivot portion 31b extends along an axial direction parallel to the first pivot portion 31a, and the second pivot portion 31b includes two shaft seats arranged at intervals in the extending direction of the second pivot portion 31b, and fixing holes are formed in the two shaft seats. The second pivot shaft also includes: a support shaft 34, which extends along the axis of the second pivot shaft, and both ends of the support shaft 34 are respectively fixed in the two fixing holes, and the support shaft 34 is spaced apart from the left end of the second connecting plate portion 33b by a predetermined distance.

[0076] Further, the second connecting plate portion 33b is formed into a flat plate shape extending along a pivot axis parallel to the second pivot axis, and the second holding portion 32b is connected to the other end of the second connecting plate portion 33b opposite to the second pivot portion 31b (for example Figure 3 The second clamping portion 32b extends along an arc line at the left end of the second connecting portion, and a matching groove 321 is defined inside the arc of the second clamping portion 32b, and a notch 322 communicating with the matching groove 321 is formed between the two ends of the second clamping portion 32b in the extending direction, that is, the second clamping portion 32b is also formed as a clamping ring with a notch 322.

[0077] During the process of assembling the first bracket, the second bracket, the detergent cover 2a and the softener cover 2b, the support shaft 34 of the second bracket is inserted into the shaft hole 35 from the opening position of the first pivot portion 31a of the first bracket, and the first bracket and the second bracket are rotatably connected by snapping, and then the detergent cover 2a is inserted into the matching groove 321 on the inner side of the first holding portion 32a, and the softener cover 2b is inserted into the matching groove 321 on the inner side of the second holding portion 32b, so that the first bracket, the second bracket, the detergent cover 2a and the softener cover 2b are assembled into a whole.

[0078] At this time, since the first clamping portion 32a and the second clamping portion 32b are both clamping rings with a notch 322, they can undergo a certain elastic deformation. Therefore, the detergent cover 2a can not only rotate relative to the first clamping portion 32a, but also be adjusted relative to the first clamping portion 32a in the length direction of the first bracket. Similarly, the softener cover 2b can not only rotate relative to the second clamping portion 32b, but also be adjusted relative to the second clamping portion 32b in the length direction of the second bracket.

[0079] In some embodiments, the angle between the bracket 3 in the first position and the second position is not less than 90°. That is, when the bracket 3 rotates from the first position to the second position, the angle through which the bracket 3 rotates is not less than 90°. For example, the angle between the bracket 3 in the first position and the bracket 3 in the second position can be 95°, 100°, 105°, 110°, 120°, 130°, 140°, 150°, 160°, 170° or 180°, etc. Thus, when the bracket 3 rotates to the second position, the distance between the sealing cover 2 and the injection port 12 in the bracket 3 can be increased to prevent the sealing cover 2 from interfering with the injection of detergent into the injection port 12.

[0080] Specifically, the rotation angle of the first bracket 3a between the first position and the second position is not less than 90°, and the rotation angle of the second bracket 3b between the first position and the second position is not less than 90°.
