Detailed implementation manners

[0027] In order to be able to more clearly understand the above-mentioned objects, features and advantages of the present application, the following will further describe the solutions of the present application. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0028] Many specific details are set forth in the following description in order to fully understand the present application, but the present application can also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments of the present application, rather than all of the embodiments.

[0029] Such as Figures 2 to 6As shown in the figure, an embodiment of the present application provides a liquid extraction device for a laundry treatment agent box, including:

[0030] A box body 1, with a receiving cavity provided inside the box body 1 for accommodating laundry treatment agents, such as detergents, fabric softeners, or disinfectants, etc. A first clamping component is provided on the side wall of at least one side of the box body 1;

[0031] A surrounding plate 2, which is arranged opposite to the inner wall of the box body 1, and a second clamping component is provided on the surrounding plate 2. The second clamping component cooperates with the first clamping component to jointly enclose a liquid extraction channel 3 between the surrounding plate 2 and the inner wall of the box body 1.

[0032] In the liquid extraction device of the embodiment of the present application, the liquid extraction channel 3 is jointly enclosed by the surrounding plate 2 and a side wall of the box body. When assembling the liquid extraction channel 3, it only needs to correspond and clamp the first clamping component and the second clamping component. Compared with the prior art, the solution of separately setting a liquid extraction channel inside the box body 1 has a simpler structure, is more convenient for assembly, and has a lower cost.

[0033] Further, in some embodiments of the present application, the lower end of the surrounding plate 2 is bent inward to the inside of the liquid extraction channel to form a flipable elastic arm 24. One end of the elastic arm 24 away from the surrounding plate 2 abuts against the inner wall of the box body 1 to block the lower end of the liquid extraction channel 3.

[0034] Specifically, as Figure 3 described, the elastic arm 24 and the surrounding plate 2 are of an integrally formed structure. The elastic modulus of the elastic arm 24 is small and it is relatively easy to bend and deform. When the surrounding plate 2 is installed on the box body 1, one end of the elastic arm 24 away from the surrounding plate 2 abuts against the first inner wall 101 of the box body 1. A certain extrusion effect is generated between the elastic arm 24 and the inner wall of the box body 1. The first 101 inner wall of the box body 1 exerts an obliquely upward force on the elastic arm 24. The elastic arm 24 squeezes the inner wall of the box body 1 under the action of its own elastic force, maintaining the effect of closing the lower end of the liquid extraction channel 3 and avoiding the leakage of the laundry treatment agent in the box body 1 in the non-liquid extraction state; when liquid extraction is required, the negative pressure adsorption method is used to make the elastic arm 24 flip upward to open the liquid extraction channel 3, which does not affect normal liquid extraction. The liquid extraction device of the laundry treatment agent box provided by the embodiment of the present application jointly encloses the liquid extraction channel 3 by the surrounding plate 2 and the side wall of the box body 1, and realizes the opening and closing of the liquid extraction channel through the flipable elastic arm 24, ensuring that the liquid extraction channel 3 does not leak when closed and can be normally liquid extracted when opened. The liquid extraction device of this laundry treatment agent box has a simple structure, is convenient for assembly, and has a low cost.

[0035] In some embodiments of the present application, a weak section 28 may be provided between the enclosure 2 and the elastic arm 24, and the thickness of the weak section 28 is less than the thickness of the enclosure 2, so as to reduce the elastic modulus of the weak section 28, so that the weak section 28 can be easily bent and deformed when subjected to force. A boss 101a is formed at the lower portion of the first inner wall 101 of the box body 1 to cooperate with the end of the elastic arm 24 away from the enclosure 2. After the enclosure 2 is installed in place, the end of the elastic arm 24 away from the enclosure 2 is partially overlapped on the boss 101a, and the upper surface of the boss 101a is an inclined surface, which gradually tilts downward in the direction away from the first inner wall 101 of the box body 1, thereby increasing the contact area between the boss 101a and the elastic arm 24, so that the lower end of the liquid collection channel 3 has a better sealing effect in the liquid collection state.

[0036] When negative pressure adsorption is performed on the upper part of the liquid collection channel 3, the weak section 28 is deformed under the action of the adsorption force, and the end of the elastic arm 24 away from the enclosure 2 flips upward and disengages from the upper surface of the boss 101a, and the lower end of the liquid collection channel 3 is opened, so that normal liquid collection operations can be performed; when the adsorption force disappears, the elastic arm 24 is reset to a state of being in contact with the upper surface of the boss 101a under the action of its own elastic force, and the lower end of the liquid collection channel 3 is sealed again.

[0037] Further, in some embodiments of the present application, one of the first card assembly and the second card assembly includes a first card slot 201, and the other includes a first card plate 103 disposed opposite to the first card slot 201, and the first card plate 103 is disposed in the first card slot 201 and has an interference fit with the first card slot 201. Specifically, the first card slot 201 or the first card plate 103 is disposed on the side of the box body 1 and the enclosure 2 disposed opposite to each other.

[0038] Exemplarily, the first card slot 201 is provided on the first inner wall 101 of the box body 1, and the first card slot 201 may be formed by being recessed on the box body 1, or may be surrounded by a limit strip 21 provided on the box body 1, and the first card plate 103 is provided correspondingly to the first card slot 201, and when the enclosure 2 is installed, the first card plate 103 is correspondingly inserted into the first card slot 201. Similarly, the first card slot 201 may also be provided on the enclosure 2, and the first card plate 103 is correspondingly provided on the first inner wall 101 of the box body 1.

[0039] There are at least two first clamping plates 103, the number of first clamping slots 201 is equal to the number of first clamping plates 103 and they are arranged in one-to-one correspondence, and any two adjacent first clamping plates 103, the surrounding plate 2, and the first inner wall 101 of the box body 1 jointly form a liquid extraction channel 3. The first clamping plate 103 and the first clamping slot 201 are interference fit, and a sealing strip is arranged between the first clamping slot 201 and the first clamping plate 103 to prevent liquid leakage between the first clamping plate 103 and the first clamping slot 201.

[0040] Further, in some embodiments of the present application, the first clamping plate 103 extends upward in a direction perpendicular to the bottom wall of the box body 1, and the number of the first clamping plates 103 is two. The two first clamping plates 103 are oppositely arranged to form the side walls of the liquid extraction channel 3. Exemplarily, the surrounding plate 2 is a rectangular plate. The length direction of the surrounding plate 2 is perpendicular to the bottom surface of the box body 1, and the width direction of the surrounding plate 2 is parallel to the bottom surface of the box body 1. The first clamping plates 103 are arranged near both ends in the width direction of the surrounding plate 2. The side walls of the box body 1, the surrounding plate 2, and the two first clamping plates 103 respectively form the side walls on the four sides of the liquid extraction channel 3, jointly enclosing a liquid extraction channel 3 with a rectangular cross-section.

[0041] Further, in some embodiments of the present application, one of the first clamping assembly and the second clamping assembly further includes a second clamping groove 202, and the other includes a second clamping plate 104 oppositely arranged with the second clamping groove 202. The second clamping plate 104 is correspondingly arranged on the side surface of the first clamping plate 103 away from the liquid extraction channel 3. The extending direction of the second clamping groove 202 is the same as that of the first clamping groove 201, and the second clamping plate 104 is slidably clamped in the second clamping groove 202. Specifically, at least one second clamping plate 104 is arranged on the side surface of each first clamping plate 103 away from the liquid extraction channel 3. The second clamping groove 202 is clamped and fixed with the second clamping plate 104 outside the first clamping plate 103. The clamping direction of the second clamping plate 104 and the second clamping groove 202 is perpendicular to the clamping direction of the first clamping plate 103 and the first clamping groove 201. The positions of the second clamping plate 104 and the second clamping groove 202 can also be interchanged, that is, the second clamping groove 202 is arranged on the first clamping plate 103, and the depth direction of the second clamping groove 202 is perpendicular to the depth direction of the first clamping groove 201. The depth direction of the first clamping groove 201 refers to the direction from the notch to the bottom of the first clamping groove 201, and the depth direction of the second clamping groove 202 refers to the direction from the notch to the bottom of the second clamping groove 202. Exemplarily, when facing the surrounding plate 2, the depth direction of the first clamping groove 201 refers to the front-back direction, and the depth direction of the second clamping groove 202 refers to the left-right direction.

[0042] The setting methods of the first clamping plate 103 and the second clamping plate 104 are mainly as follows:

[0043] (1) Both of the two first clamping plates 103 are arranged on the first inner wall 101 of the box body 1. Two first clamping grooves 201 are correspondingly arranged on the surrounding plate 2. The two second clamping plates 104 are arranged in one-to-one correspondence with the two first clamping plates 103. The second clamping groove 202 is arranged on the surrounding plate 2 and is correspondingly arranged with the second clamping plate 104.

[0044] (2) Two first clamping plates 103 are both arranged on the first inner wall 101 of the box body 1. Two first clamping grooves 201 are correspondingly arranged on the surrounding plate 2. Two second clamping plates 104 are arranged on the surrounding plate 2. Each first clamping plate 103 is provided with a second clamping groove 202 correspondingly arranged with the second clamping plate 104.

[0045] (3) One first clamping plate 103 is arranged on the first inner wall 101 of the box body 1. The surrounding plate 2 is correspondingly provided with a first clamping groove 201. The other first clamping plate 103 is arranged on the surrounding plate 2 and is arranged at an interval with the first clamping groove 201 arranged on the surrounding plate 2. The first clamping groove 201 is correspondingly arranged at the corresponding position on the first inner wall 101 of the box body 1; the first clamping plate 103 is provided with a second clamping groove 202 or a second clamping plate 104.

[0046] (4) Two first clamping plates 103 are both arranged on the surrounding plate 2. Two first clamping grooves 201 are correspondingly arranged on the first inner wall 101 of the box body 1. The first clamping plate 103 is provided with a second clamping groove 202 or a second clamping plate 104.

[0047] Further, in some embodiments of the present application, two first clamping plates 103 are both arranged on the side wall of the box body 1. The two first clamping plates 103 are arranged at an interval. And the second clamping plate 104 is arranged on the side surface opposite to the first clamping plate 103. Each first clamping plate 103 corresponds to one second clamping plate 104. And the second clamping plate 104 is perpendicularly arranged with the first clamping plate 103; two limiting strips 21 are arranged at the position on the surrounding plate 2 opposite to the first clamping plate 103. The two limiting strips 21 are arranged at an interval. A first clamping groove 201 is formed between the two limiting strips 21. That is to say, a total of 4 limiting strips 21 are arranged on the surrounding plate 2. Every two limiting strips 21 are in a group. The two limiting strips 21 in each group define a first clamping groove 201.

[0048] Further, as Figure 2 and Figure 6 shown, in some embodiments of the present application, both ends of the surrounding plate 2 in the width direction are bent towards the direction close to the side wall of the box body 1 to form a first connecting plate 22. One end of the first connecting plate 22 far away from the surrounding plate 2 is bent inwards to form a second connecting plate 23. The second connecting plate 23 is arranged opposite to the surrounding plate 2. And the second connecting plate 23, the first connecting plate 22 and the surrounding plate 2 jointly define a second clamping groove 202. The notch of the second clamping groove 202 faces parallel to the surrounding plate 2. The notch of the first clamping groove 201 faces perpendicular to the surrounding plate 2. The width direction of the surrounding plate 2 is also Figure 6 the up and down direction in

[0049] Further, in some embodiments of the present application, the bending angle between the first connecting plate 22 and the surrounding plate 2 is 90°, the bending angle between the second connecting plate 23 and the surrounding plate 2 is 90°, and the second connecting plate 23 and the surrounding plate 2 are located on the same side of the first connecting plate 22 to form a second card slot 202 that can be engaged with the second engaging plate 104.

[0050] The width of the second card slot 202 is greater than the width of the second engaging plate 104. Exemplarily, when the surrounding plate 2 is installed on the box body 1, one side surface of the second engaging plate 104 facing the first inner wall 101 of the box body 1 abuts against one side surface of the second connecting plate 23 facing the surrounding plate 2, and one end of the first engaging plate 103 away from the first inner wall 101 of the box body 1 abuts against the bottom of the first card slot 201. That is to say, the movement of the surrounding plate 2 in the direction close to or away from the first inner wall 101 of the box body 1 when inserted into the box body 1 is restricted by the first engaging plate 103 and the second engaging plate 104, ensuring that the surrounding plate 2 can only move downward to be installed in place or move upward to disengage from the box body 1.

[0051] Further, in some embodiments of the present application, the projection of the end of the second connecting plate 23 away from the first connecting plate 22 on the surrounding plate 2 is located outside the corresponding first card slot 201, avoiding the mutual interference between the second connecting plate 23 and the first engaging plate 103 during the installation of the surrounding plate 2. The outside of the first card slot 201 refers to the side relatively far from the center line of the surrounding plate 2 along the width direction of the surrounding plate 3.

[0052] There is a certain distance between the end of the limiting strip 21 away from the surrounding plate 2 and the second engaging plate 104, avoiding the interference of the limiting strip 21 on the installation of the second engaging plate 104.

[0053] Further, in some embodiments of the present application, a cover plate 25 is provided at the upper end of the surrounding plate 2, the upper end of the first engaging plate 103 is connected with a limiting plate 105, the cover plate 25 overlaps on the limiting plate 105 to block the upper end of the liquid extraction channel 3, and a negative pressure liquid extraction port 102 is provided at the corresponding position of the upper part of the box body 1 and the liquid extraction channel 3. Specifically, the projection of the cover plate 25 on the bottom wall of the box body 1 does not coincide with the projection of the second card slot 202 on the bottom wall of the box body 1, and there is a certain gap between the cover plate 25 and the first inner wall 101 of the box body 1 after the surrounding plate 2 is installed in place, avoiding the interference problem between them. The setting of the cover plate 25 avoids the outflow of the solution from the upper end of the liquid extraction channel 3 during liquid extraction.

[0054] Further, in some embodiments of the present application, one end of the cover plate 25 away from the surrounding plate 2 is bent downward to form a first positioning plate 26, a second positioning plate 27 is provided on the lower side surface of the cover plate 25 opposite to the first positioning plate 26, and a third card slot is formed between the first positioning plate 26 and the second positioning plate 27, and the limiting plate 105 is clamped in the third card slot.

[0055] A liquid extraction port 102 is provided at a position corresponding to the upper part of the liquid extraction channel 2. A negative pressure adsorption device is arranged at the liquid extraction port 102 to provide negative pressure into the liquid extraction channel 3, so that the clothing treatment agent in the box body 1 can be taken out through the liquid extraction channel 3.

[0056] When installing the surrounding plate, the surrounding plate 2 is inserted into the box body 1 from the upper end of the box body downwards. Before insertion, first align the first clamping plate 103 with the first clamping groove 201 and align the second clamping plate 104 with the second clamping groove 202. When the surrounding plate 2 moves downwards, the corresponding first clamping plate 103 is inserted into the first clamping groove 201, and the corresponding second clamping plate 104 is inserted into the second clamping groove 202. When the surrounding plate 2 cannot be pushed down any further, the surrounding plate 2 is installed in place. At this time, the elastic arm 24 just fits and abuts against the inclined mating surface on the boss 101a, blocking the lower end of the liquid extraction channel 3. When negative pressure is provided from the liquid extraction port 102, the elastic arm 24 flips upwards, and the lower end of the liquid extraction channel 3 is opened, and the clothing treatment agent in the accommodation cavity can be taken out normally. When the negative pressure at the liquid extraction port 3 disappears, the elastic arm 24 resets under its own elasticity and fits against the mating surface on the boss 101a again to block the lower end of the liquid extraction channel 3, avoiding liquid leakage during the non-liquid extraction state. This liquid extraction device jointly encloses the liquid extraction channel by the surrounding plate and the side wall of the box body, and realizes the opening and closing of the liquid extraction channel through the flipable elastic arm, ensuring that there is no liquid leakage when the liquid extraction channel is closed and normal liquid extraction can be carried out when it is opened. The liquid extraction device of this clothing treatment agent box has a simple structure, is convenient for assembly, and has a low cost.
