When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0038] like Figures 1 to 8 As shown, the embodiment of the present application provides a detergent box assembly 100, including:

[0039] A box body 110, wherein the box body 110 has a receiving cavity S1;

[0040] A fixing seat 130, wherein the fixing seat 130 has a liquid inlet channel S2, wherein the liquid inlet channel S2 is connected to the accommodating chamber S1; a first limiting structure 131 is disposed on the outer side of the fixing seat 130;

[0041] The sealing cover 120 is threadedly matched with the fixing seat 130; the sealing cover 120 opens the liquid inlet channel S2 when it rotates along the first direction, and closes the liquid inlet channel S2 when it rotates along the second direction; a second limiting structure 121 is provided on the sealing cover 120; when the sealing cover 120 closes the liquid inlet channel S2, the first limiting structure 131 and the second limiting structure 121 abut against each other, and limit the sealing cover 120 from rotating along the first direction; wherein, the sealing cover 120 is elastic, and the first limiting structure 131 and the second limiting structure 121 are disengaged from the abutment relationship when the sealing cover 120 is subjected to the extrusion force F, thereby causing the sealing cover 120 to rotate along the first direction to open the liquid inlet channel S2.

[0042] In the technical solution of the embodiment of the present application, detergent is added into the accommodating cavity S1 of the box body 110 through the liquid inlet channel S2 on the fixing seat 130. When detergent needs to be added, the liquid inlet channel S2 is opened by rotating the sealing cover 120 in the first direction; after the detergent is added, the liquid inlet channel S2 is closed by rotating the sealing cover 120 in the second direction. Since a first limiting structure 131 is provided on the outer side of the fixing seat 130, and a second limiting structure 121 is provided on the sealing cover 120; when the sealing cover 120 closes the liquid inlet channel S2, the first limiting structure 131 and the second limiting structure 121 abut against each other and limit the sealing cover 120 from rotating along the first direction, thereby preventing children from accidentally opening the sealing cover 120 and touching or swallowing detergent; when an adult needs to open the sealing cover 120, since the sealing cover 120 is elastic, the sealing cover 120 is squeezed so that the sealing cover 120 is subjected to a squeezing force, so that the first limiting structure 131 and the second limiting structure 121 are separated from the abutting relationship, and then the sealing cover 120 is not restricted by the first limiting structure 131 and can be rotated in the first direction to open the sealing cover 120, thereby completing the addition of detergent. Therefore, the detergent box assembly 100 of the embodiment of the present application has the function of preventing children from disassembling it, which effectively prevents children from touching or accidentally ingesting the detergent solvent inside the detergent box. At the same time, the sealing cover 120 can be easily removed by adults, which can prevent children from accidentally touching it and facilitate adult operation.

[0043] In a specific embodiment, the first direction and the second direction are related to the thread rotation direction of the fixing seat, and no specific limitation is made. For example, in some embodiments, the first direction is counterclockwise and the second direction is clockwise. For another example, in some other embodiments, the first direction is clockwise and the second direction is counterclockwise.

[0044] As an optional implementation of the above embodiment, there are multiple first limiting structures 131, and the multiple first limiting structures 131 are arranged at intervals along the circumference of the fixing seat 130; there are multiple second limiting structures 121, and the multiple second limiting structures 121 are arranged at intervals along the circumference of the sealing cover 120; when the sealing cover 120 closes the liquid inlet channel S2, the first limiting structure 131 and the second limiting structure 121 are in one-to-one correspondence. Through such an arrangement, when there is no need to open the sealing cover 120 and an attempt is made to apply a first direction rotation to the sealing cover 120 by mistake, the multiple first limiting structures 131 and the multiple second limiting structures 121 are respectively in one-to-one correspondence. It can be avoided that when a large torque along the first direction is applied to the sealing cover 120, the abutment time of the first limiting structure 131 and the second limiting structure 121 can be avoided, thereby improving the reliability of preventing accidental touch and opening.

[0045] For example, Figure 4 and Figure 6As shown, there are two first limiting structures 131 and two second limiting structures 121, and the two first limiting structures 131 are evenly arranged (i.e., located on the same diameter). For another example, in some embodiments, there may be three first limiting structures 131 and two second limiting structures 121, and the three first limiting structures 131 are evenly arranged (i.e., the three first limiting structures 131 are arranged at 120°).

[0046] As an optional implementation of the above embodiment, Figure 5 As shown, the first limiting structure 131 has a first inclined surface 1311 and a first abutting surface 1312 arranged opposite to the first inclined surface 1311. The second limiting structure 121 has a second inclined surface 1211 and a second abutting surface 1212 arranged opposite to the second inclined surface 1211, and the second inclined surface 1211 is located in front of the second abutting surface 1212 in the second direction. When the sealing cover 120 rotates along the second direction, the second inclined surface 1211 abuts against the first inclined surface 1311 and through the first limiting structure 131, the second limiting structure 121 is located in front of the first limiting structure 131 in the second direction, so that the first abutting surface 1312 and the second abutting surface 1212 abut against each other, limiting the sealing cover 120 from rotating along the first direction when no extrusion force is applied. In an embodiment, when the sealing cover 120 is closed, the second inclined surface 1211 acts on the first inclined surface 1311, and the second limiting structure 121 gradually passes through the first limiting structure 131 so as to be located on the rear side of the first limiting structure 131 in the second direction; at this time, the first abutting surface 1312 and the second abutting surface 1212 abut against each other, thereby limiting the sealing cover 120 from rotating along the first direction when no extrusion force is applied.

[0047] In the embodiment, the structures of the plurality of first limiting structures 131 and the plurality of second limiting structures 121 may refer to the above embodiment.

[0048] As an optional implementation of the above embodiment, Figure 5 As shown, the first abutting surface 1312 and the second abutting surface 1212 extend along the radial direction of the fixing seat 130. Figure 6As shown, the first abutting surface 1312 and the second abutting surface 1212 extend radially. When the sealing cover 120 is squeezed, the sealing cover 120 is deformed, the second limiting structure 121 moves radially, and the second abutting surface 1212 can be radially offset from the first abutting surface 1312, so that the second limiting structure 121 is free from the restriction of the first limiting structure 131, and the sealing cover 120 can be opened along the first direction. The first abutting surface 1312 and the second abutting surface 1212 extend radially. When the sealing cover 120 closes the liquid inlet channel S2 and is not subjected to a squeezing force, if a child applies a torque in the first direction, the first abutting surface 1312 applies a circumferential force to the second abutting surface 1212 to offset the torque, and the child cannot open the sealing cover 120.

[0049] As an optional implementation of the above embodiment, Figure 4 and Figure 5 As shown, the first inclined surface 1311 and the first abutting surface 1312 are arranged at a first angle, and the second inclined surface 1211 and the second abutting surface 1212 are arranged at a second angle α; the value range of the first angle and the second angle is 30-60°. In the embodiment, the first angle and the second angle α are set to 30-60°, so that the second limiting structure 121 can easily pass through the first limiting structure 131 when the sealing cover 120 closes the liquid inlet channel S2, and when the sealing cover 120 is accidentally touched to try to open the liquid inlet channel S2, the limiting reliability of the first limiting structure 131 on the second limiting structure 121 is improved.

[0050] In an embodiment, the value range of the first angle and the second angle may be 30°, 35°, 40°, 45°, 50°, 55°, 60°.

[0051] As an optional implementation of the above embodiment, the sealing cover 120 is provided with a pressing portion (not shown in the example), and the pressing portion and the second limiting structure 121 are arranged in a staggered manner in the circumferential direction of the sealing cover 120. In the embodiment, the pressing portion can be a depression, a finger mark, etc. on the circumferential side of the sealing cover 120, which is used to prompt an adult to press this portion when opening the sealing cover 120 so that the second limiting structure 121 and the first limiting structure 131 are out of contact. Figure 4 and Figure 6 It can be seen that the extrusion portion and the second limiting structure 121 are staggered in the circumferential direction of the sealing cover 120, so that when squeezed, the sealing cover 120 is deformed, the second limiting structure 121 moves radially and breaks contact with the first limiting structure 131, and the sealing cover 120 can be rotated along the first direction to open the liquid inlet channel S2.

[0052] As an optional implementation of the above embodiment, the outer side of the fixing seat 130 has a first thread segment 132, and the inner side of the sealing cover 120 has a second thread segment, and the first thread segment 132 cooperates with the second thread segment.

That is, after the sealing cover 120 is screwed onto the fixing seat 130, the second limiting structure 121 of the sealing cover 120 will be abutted by the first limiting structure 131 to limit the sealing cover 120 from opening the liquid inlet channel S2 along the first direction.

[0053] As an optional implementation of the above embodiment, the accommodating chamber S1 includes a first accommodating chamber and a second accommodating chamber separated from each other. In the embodiment, a partition is provided inside the box body 110 to divide the accommodating chamber S1 into a first accommodating chamber and a second accommodating chamber, which can be used to accommodate laundry detergent and softener, respectively.
