DETAILED DESCRIPTION

[0076] The present disclosure will be further described below in conjunction with the accompanying drawings and specific embodiments. The following description is only intended to illustrate the basic principles of the present disclosure and is not intended to limit the present disclosure.

[0077] According to a first aspect of an embodiment of the present application, a dispensing system 10 is provided, comprising: a supply line 700 for supplying liquid; and a dispensing unit 100, which is in communication with the supply line 700 and adapted to communicate with a laundry processing chamber of a laundry processing device 2000. Thus, detergent can be dispensed into the laundry processing chamber via the supply line 700 and the dispensing unit 100, thereby increasing the versatility of application of the laundry processing device 2000.

[0078] As shown in Figures 1 to 19, according to the delivery system 10 of the embodiment of the present disclosure, its delivery unit 100 includes: a box body 110, which is formed with a liquid storage cavity 1101 and a delivery port 1102 connected to the liquid storage cavity 1101; a cover body 120, which is movably arranged on the box body and is used to cover or open the delivery port 1102, and the cover body 120 has at least two operating ends 1201; wherein, when the cover body 120 covers the delivery port 1102, an operating space 1202 is formed between each operating end 1201 and the box body 110.

[0079] The dispensing unit 100 provided in the embodiment of the present disclosure includes a box body 110 and a cover body 120, wherein the box body 110 is formed with a liquid storage cavity 1101 and a dispensing port 1102. In actual application, the liquid storage cavity 1101 can be used to accommodate cleaning agent, and the dispensing port 1102 is connected to the liquid storage cavity 1101, so that the user can inject cleaning agent into the liquid storage cavity 1101 through the dispensing port 1102; the cover body 120 is arranged on the box body 110 and can move relative to the box body 110, so as to The cover body 120 can cover or open the aforementioned liquid injection port by moving relative to the box body 110. When the cover body 120 covers the liquid injection port, the aforementioned liquid storage chamber 1101 and the external space can be separated from each other, thereby preventing substances in the external environment from entering the liquid storage chamber 1101, which is beneficial to ensuring the internal cleanliness of the liquid storage chamber 1101. When the cover body 120 opens the aforementioned liquid injection port, the aforementioned liquid storage chamber 1101 can be connected to the external space, thereby facilitating the filling of cleaning agent or the cleaning and maintenance of the liquid storage chamber 1101.

[0080] The aforementioned cover body 120 has an operating end 1201. In actual application, the aforementioned operating end 1201 can be used to withstand the driving force, which is the external force used to drive the cover body 120 to move relative to the box body 110 to realize the opening or closing of the liquid injection port. For example, when the user manually operates the cover body 120, the aforementioned operating end 1201 can be used to contact the operator's hand and withstand the driving force applied by the operator's hand; accordingly, when the aforementioned cover body 120 covers the aforementioned injection port 1102, an operating space 1202 is formed between the aforementioned operating end 1201 and the aforementioned box body 110. The aforementioned operating space 1202 can provide a passable space for the user's hand to approach and contact the aforementioned operating end 1201, thereby facilitating the user to operate the cover body 120.

[0081] The number of the aforementioned operating ends 1201 is at least two, and when the cover body 120 covers the injection port 1102, an operating space 1202 is formed between each operating end 1201 and the box body 110, so that the user's hand can contact multiple parts of the cover body 120 at the same time (for example: opposite sides, which is convenient for the user to hold), and the aforementioned driving force can be applied to multiple parts of the cover body 120 at the same time, so that during the operation of switching the injection port from a covered state to an open state, on the one hand, it can be beneficial to increase the contact area between the cover body 120 and the user's hand, expand the feasible contact orientation between the cover body 120 and the user's hand, thereby improving the user's force application convenience during operation, reducing the difficulty of opening the injection port 1102, and improving the product's user experience; on the other hand, it is also beneficial to prevent the cover body 120 from being subjected to a more concentrated driving force, improve the force dispersion and balance of the cover body 120, thereby reducing the probability of damage to the cover body 120 in actual application, and reducing the maintenance and use costs of the injection unit 100.

[0082] It can be understood that the aforementioned at least two operating ends 1201 can be at least two different ends of the aforementioned cover body 120. For example, when the aforementioned cover body 120 is a plate-like structure, the aforementioned operating end 1201 can be a plate end in the length direction or width direction of the aforementioned plate-like structure. The aforementioned at least two operating ends 1201 can be adjacent to each other or can be spaced apart from each other.

[0083] For example, as shown in FIG4 , the cover body 120 can be a generally rectangular plate-like structure (in some embodiments, the cover body 120 is a square plate-like structure), so that the cover body 120 has four ends in the length and width directions. Thus, for the cover body 120 with a rectangular plate-like structure, the number of the aforementioned operating ends 1201 can be greater than or equal to two and less than or equal to four. Taking into account the connection between the cover body 120 and the box body 110, the number of operating ends 1201 of the cover body 120 with a rectangular plate-like structure can be less than or equal to three, that is, in actual application, one end of the cover body 120 in the length or width direction can be used to connect to the box body 110. It can be understood that the shape of the cover body 120 can be, but is not limited to, a rectangular plate-like structure, and can also be other polygonal plate-like structures, such as a triangular plate-like structure, a pentagonal plate-like structure, a hexagonal plate-like structure, etc. Accordingly, the number of operating ends 1201 can also be set in combination with the shape of the cover body 120 and actual needs.

[0084] It should be noted that some conventional dispensing units 100 typically include a box body and a lid body. The box body defines an open liquid storage space, and the lid body is used to cover or open the opening of the liquid storage space. Furthermore, the box body often has a small notch structure on one side of the lid body. When the lid body covers the opening, if a user needs to open the opening, they can only insert a single fingernail through the small notch structure on the side of the lid body. As a result, the user can often only apply force to the lid body from a single position. This is not only difficult to operate and has a poor user experience, but also, due to the cramped space, it is not easy for the user to control the direction and magnitude of the force applied, which can easily cause damage to the lid body. The dispensing unit 100 provided in the present embodiment, based on the above-mentioned configuration, can increase the contact area between the lid body 120 and the user's hand, expand the possible contact directions between the lid body 120 and the user's hand, improve the user's convenience in applying force during operation, and facilitate improving the force distribution and balance of the lid body 120, thereby reducing the chance of damage to the lid body 120 during actual use.

[0085] It should be noted that, in actual applications, the dispensing unit 100 provided in the embodiment of the present disclosure can be used as a component of a cleaning device, and the aforementioned cleaning device can be, but is not limited to, a washing machine, a dishwasher, a sweeping robot, etc. Accordingly, the aforementioned cleaning agent can be, but is not limited to, laundry liquid, softener, detergent, washing powder, disinfectant, etc. Taking the application of the aforementioned dispensing unit 100 to a washing machine as an example, the aforementioned box body 110 can be set in the casing of the washing machine, and the aforementioned liquid storage chamber 1101 can be used to store detergents such as laundry liquid and softener. The liquid storage chamber 1101 of the aforementioned dispensing unit 100 can be used to connect to the detergent dispensing flow path of the washing machine. It can be understood that the output end of the aforementioned detergent dispensing flow path is connected to the clothes processing chamber of the washing machine, so that during the process of washing clothes, the detergent in the dispensing unit 100 can be dispensed into the clothes processing chamber through the detergent dispensing flow path to participate in the clothes washing operation.

[0086] In some feasible examples, the aforementioned operating end 1201 may be provided with anti-slip grooves to further facilitate the user to apply force to the cover body 120.

[0087] In some feasible examples, the length of the aforementioned operating space 1202 is greater than or equal to the length of the aforementioned operating end 1201, so that the operating space 1202 can correspond to the entire side of the cover body 120, expand the distribution range of the operating space 1202, and further improve the operating convenience of the cover body 120. It can be understood that the length of the aforementioned operating end 1201 is also the dimension of the operating end 1201 in the extension direction. Taking the case where the cover body 120 is a rectangular plate structure as an example, if the aforementioned operating end 1201 is one end in the length direction of the rectangular plate structure, then the operating end 1201 corresponds to the long side of the rectangular plate structure. Accordingly, the operating end 1201 extends along the length direction of the rectangular plate structure. Similarly, if the operating end 1201 is one end in the length direction of the rectangular plate structure, then the operating end 1201 extends along the width direction of the rectangular plate structure. Accordingly, the length direction of the aforementioned operating space 1202 is consistent with the length direction of the aforementioned operating end 1201.

[0088] As shown in FIG. 1 , FIG. 2 , FIG. 4 and FIG. 5 , in some examples, there are two operating ends 1201 , and the two operating ends 1201 face away from each other.

[0089] In this technical solution, the number of the aforementioned operating ends 1201 can be two, and the two aforementioned operating ends 1201 are separated from each other, that is, the two ends of the cover body 120 that are separated from each other can serve as the aforementioned two operating ends 1201. Based on the aforementioned setting, the spacing distance between the aforementioned two operating ends 1201 can be expanded, and then while being able to facilitate the user to apply force to different parts of the cover body 120 at the same time, the force balance of the cover body 120 during use is further improved, which is beneficial to further reduce the chance of damage to the cover body 120 and improve the convenience of opening the injection port 1102.

[0090] It is understandable that, when the two operating ends 1201 face away from each other, when the cover 120 covers the aforementioned delivery port 1102 , two operating spaces 1202 will be correspondingly formed between the cover 120 and the box body 110 .

[0091] It is understood that in actual use, the size of the cover 120 can be set according to actual needs. When the cover 120 is relatively small, the user can operate the cover 120 with a single finger. Based on the above configuration, the distance between the two operating spaces 1202 can be relatively large, thereby facilitating the user's hand to operate with a larger opening, thereby reducing the possibility of interference between the user's fingers during operation, and further improving the ease of operation of the cover 120. Accordingly, when the cover 120 is relatively large, the user can grasp the cover 120 to operate it, that is, the user can apply force to each operating end 1201 with two fingers, which further improves the ease of operation of the cover 120.

[0092] In some feasible examples, the cover portion 120 has a width similar to that of the box body portion 110 (for example, the same or slightly smaller width), and has an overall shape that is compatible with the box body portion 110 (for example: an overall shape consistent with the box body portion 110), thereby ensuring that the cover portion 120 has a higher width for user operation while making the dispensing unit 100 have a higher aesthetics.

[0093] In some feasible examples, the distance between the two operating ends 1201 that are separated from each other is adapted to the width of the box body 110. For example, the distance between the two operating ends 1201 that are separated from each other can be greater than or equal to 0.5 times the width of the box body 110, and less than or equal to 0.95 times the width of the box body 110. On the one hand, this can make the distance between the two operating ends 1201 that are separated from each other larger, increase the span between the operating ends 1201 and the overall width of the cover body 120, thereby facilitating the user's hand-stretching operation and further improving the operational convenience of the cover body 120. On the other hand, it can also avoid the width of the cover body 120 being too large, which is conducive to ensuring the structural compactness of the delivery unit 100 and improving the aesthetics of the delivery unit 100. For example, the distance between the two operating ends 1201 facing away from each other can be but not limited to 0.55 times, 0.6 times, 0.7 times, 0.8 times, 0.9 times, etc., of the width of the box body 110. The aforementioned distance can be set according to actual needs and is not limited here.

[0094] As shown in Figures 1 to 3, in some examples, the box body 110 is formed with a groove 1103, and the delivery port 1102 is arranged in the groove 1103. When the cover body 120 covers the delivery port 1102, the cover body 120 is located in the groove 1103, and an operating space 1202 is defined in the groove 1103.

[0095] In this technical solution, the box body 110 may be formed with a groove 1103, and the delivery port 1102 may be formed in the groove 1103, that is, the groove 1103 and the liquid storage chamber 1101 may be arranged adjacent to each other and communicate with each other. When the cover 120 covers the delivery port 1102, the cover 120 is located in the groove 1103 and defines the operating space 1202 in the groove 1103, thereby avoiding the cover 120 from protruding from the box body 110, improving the structural concealment of the cover 120 when covering the delivery port 1102, and thus improving the aesthetics of the delivery unit 100 and further enhancing the user experience of the product. On the other hand, it can also reduce the possibility of external structures contacting the cover 120, reduce the probability of the delivery port 1102 being accidentally opened, and help to further avoid damage to the cover 120, providing further protection for reducing the use cost of the delivery unit 100.

[0096] As shown in Figures 1 to 3, in some feasible examples, the portion of the box body 110 corresponding to the operating end 1201 may be formed with an opening, and the opening is connected to the groove 1103. Accordingly, when the cover body 120 covers the delivery port 1102, the opening is connected to the operating space 1202, thereby facilitating the passability of the operating space 1202, and further facilitating the user's hand to contact the operating end 1201 of the cover body 120 through the operating space 1202, thereby further improving the convenience of the opening operation of the delivery port 1102.

[0098] In this technical solution, the aforementioned delivery port 1102 can be formed on the bottom wall of the aforementioned groove 1103. It can be understood that the aforementioned groove 1103 is an open groove, and the bottom wall of the aforementioned groove 1103 is also the groove wall opposite to the aforementioned groove. When the aforementioned cover body 120 covers the aforementioned delivery port 1102, one side of the cover body 120 can abut against the bottom wall of the aforementioned groove 1103 to achieve coverage of the aforementioned delivery port 1102. Accordingly, the side of the cover body 120 away from the delivery port 1102 can be arranged to be aligned with the box body 1103. For example, it is flush with the side of the box body 110 on which the aforementioned groove 1103 is formed. Then, when the aforementioned cover body 120 covers the aforementioned delivery port 1102, the side of the delivery unit 100 on which the aforementioned cover body 120 is provided can have a higher surface flatness. On the one hand, it is beneficial to improve the shape matching between the cover body 120 and the groove 1103, and further improve the aesthetics of the delivery unit 100. On the other hand, it is also beneficial to further enhance the structural compactness of the delivery unit 100 and enhance the miniaturization level of the delivery unit 100.

[0099] It can be understood that by opening the aforementioned delivery port 1102 on the bottom wall of the aforementioned groove 1103, the aforementioned delivery port 1102 can also be directed towards the notch of the aforementioned groove 1103, so that when the cover body 120 opens the aforementioned delivery port 1102, it can be further convenient for the operator to inject the cleaning agent into the aforementioned delivery port 1102, which is conducive to further improving the ease of use of the delivery unit 100.

[0100] As shown in Figures 1 to 8, in some examples, the cover body 120 includes a main plate segment 121, a first curved plate segment 122 and a second curved plate segment 123, and the main plate segment 121 is connected between the first curved plate segment 122 and the second curved plate segment 123; the groove 1103 includes a main groove segment 1103a, a first side groove segment 1103b and a second side groove segment 1103c, and the main groove segment 1103a is located between the first side groove segment 1103b and the second side groove segment 1103c; wherein, the shape of the main plate segment 121 is adapted to the shape of the main groove segment 1103a, and the first curved plate segment 122 and the second curved plate segment 123 are respectively consistent with the curvature at the corresponding positions of the box body 110.

[0101] In this technical solution, the aforementioned cover body 120 may include a first arc-shaped plate segment 122, a main body plate segment 121 and a second arc-shaped plate segment 123 connected in sequence. Correspondingly, the aforementioned groove 1103 may include a first side groove segment 1103b, a main body groove segment 1103a and a second side groove segment 1103c connected in sequence. The aforementioned first arc-shaped plate segment 122, the main body plate segment 121 and the second arc-shaped plate segment 123 correspond to the aforementioned first side groove segment 1103b, the main body groove segment 1103a and the second side groove segment 1103c, respectively. That is, when the aforementioned cover body 120 covers the aforementioned loading port 1102, the first arc-shaped plate segment 122 is located in the aforementioned first side groove segment 1103b, and the main body plate segment 121 is located in the aforementioned 21 is located in the main groove section 1103a, and the second arc-shaped plate section 123 is located in the second side groove section 1103c. It can be understood that the aforementioned delivery port 1102 can be opened on the bottom wall of the aforementioned main groove section 1103a. Accordingly, the cover body 120 can use the main plate section 121 to cover or open the aforementioned delivery port 1102, and based on the aforementioned setting, both ends of the main plate section 121 are arc-shaped plate sections, so that the contour of the outer edge of the cover body 120 can be smoother, which is conducive to reducing the angular structure of the edge of the cover body 120, reducing the risk of scratches when the user operates, further improving the convenience of opening and closing the delivery port 1102, and helping to further improve the aesthetics of the delivery unit 100.

[0102] Among them, the shape of the main plate section 121 can be adapted to the shape of the main groove section 1103a, so that when the cover body 120 covers the delivery port 1102, the main plate section 121 and the main groove section 1103a can be more fitted together, making it convenient to make the main plate section 121 and the corresponding partial groove openings of the main groove section 1103a flush, and reduce the fitting gap between the main plate section 121 and the main groove section 1103a, which is beneficial to improve the aesthetics of the delivery unit 100 while reducing the risk of liquid overflow.

[0103] At the same time, the first curved plate segment 122 and the second curved plate segment 123 can be set to be consistent with the curvature of the corresponding position of the box body 110. It should be noted that the position corresponding to the aforementioned box body 110 and the aforementioned first curved plate segment 122 includes the first side groove segment 1103b, so that the aforementioned first side groove segment 1103b can be a curved groove segment; the position corresponding to the aforementioned box body 110 and the aforementioned first curved plate segment 122 includes the second side groove segment 1103c, so that the aforementioned second side groove segment 1103c can also be a curved groove segment; and based on the aforementioned setting, each curved plate segment and the corresponding side groove segment can have a curvature with a high degree of matching, which is conducive to making each curved plate segment more fit against the groove wall of the corresponding side groove segment when the cover body 120 covers the delivery port 1102, thereby reducing the matching gap between the curved plate segment and the corresponding side groove segment, which is conducive to further improving the aesthetics of the delivery unit 100 while reducing the risk of liquid overflow.

[0104] For example, as shown in Figures 2, 3 and 5, the aforementioned delivery port 1102 is formed on the bottom wall of the main groove section 1103a. The bottom wall of the aforementioned main groove section 1103a can be a plane. Correspondingly, the main plate section 121 can be a plate-like structure with high flatness, so that the main groove section 1103a and the main plate section 121 can be matched; the bottom walls of the first side groove section 1103b and the second side groove section 1103c are inclined from the inside to the outside, and can also be arc-shaped walls, and smoothly transition with the bottom wall of the main groove section 1103a, thereby increasing the operating space 1202 of the user's fingers and improving the smoothness of the groove wall of the groove 1103, which is conducive to reducing the angular structure of the groove wall of the groove 1103. Improve the cleaning convenience and aesthetics of the groove 1103; the aforementioned curved wall surface can be a convex curved surface, that is, the aforementioned curved wall surface is a curved surface that is convex toward the space in the groove, and the aforementioned first curved plate segment 122 is used to match the plate surface of the bottom wall of the first side groove segment 1103b can be a concave curved surface, and the aforementioned second curved plate segment 123 is used to match the plate surface of the bottom wall of the second side groove segment 1103c can also be a concave curved surface, so that each curved plate segment can adapt to the corresponding side groove segment, and can accordingly make the first curved plate segment 122 and the second curved plate segment 123 facing away from the side of the delivery port 1102 to be convex curved surface, which is beneficial to improve the aesthetics of the cover body 120 while ensuring the ease of operation of the cover body 120.

[0105] As shown in FIG. 1 to FIG. 3 , FIG. 7 and FIG. 8 , in some feasible examples, the cover portion 120 and the box body portion 110 have a consistent overall shape. For example, the side of the box body 110 on which the groove 1103 is formed may also have a main decorative surface 1104, a first side decorative surface 1105 and a second side decorative surface 1106, and the main decorative surface 1104, the first side decorative surface 1105 and the second side decorative surface 1106 are all located on the groove periphery of the groove 1103, and the main decorative surface 1104 corresponds to the main groove section 1103a, the first side decorative surface 1105 corresponds to the first side groove section 1103b, and the second side decorative surface 1106 corresponds to the second side groove section 1103c; accordingly, the position of the box body 110 corresponding to the first curved plate section 122 also includes the first side decorative surface 1105, and the position of the box body 110 corresponding to the second curved plate section 123 also includes the second side decorative surface 1106, that is, the first side decorative surface 1105 corresponds to the second side decorative surface 1106 can both be curved surfaces, and the curvature of the aforementioned first side finishing surface 1105 and the curvature of the aforementioned second side finishing surface 1106 are respectively consistent with the curvature of the aforementioned first curved plate segment 122 and the curvature of the aforementioned second curved plate segment 123; when the cover body 120 covers the aforementioned delivery port 1102, the side of the first curved plate segment 122 facing away from the delivery port 1102 is flush with the first side finishing surface 1105, the side of the second curved plate segment 123 facing away from the delivery port 1102 is flush with the second side finishing surface 1106, and the side of the main plate segment 121 facing away from the delivery port 1102 is flush with the main finishing surface 1104. Based on the above-mentioned setting, when the cover body 120 covers the aforementioned delivery port 1102, the side of the delivery unit 100 provided with the aforementioned cover body 120 can have a higher surface flatness, which is conducive to further improving the aesthetics of the delivery unit 100.

[0106] As shown in Figures 1 to 8, in some feasible examples, the edge of the groove 1103 can have multiple rounded transition structures, and accordingly, the edge of the cover body 120 can also have multiple rounded transition structures, which is conducive to further reducing the sharp corners of the groove 1103 and the cover plate, thereby helping to improve the aesthetics of the delivery unit 100 while ensuring the safety of operation.

[0107] In some feasible examples, the first arc-shaped plate segment 122 , the main body plate segment 121 and the second arc-shaped plate segment 123 are an integrated structure.

[0108] As shown in Figures 4 to 6, in some feasible examples, the aforementioned cover body 120 may also include a delivery plug 124, which is arranged on one side of the aforementioned main plate section 121 and includes a raised plug frame and a sealing ring, which is used to removably close the aforementioned delivery port 1102. When the cover body 120 covers the delivery port 1102, the delivery plug 124 is inserted into the aforementioned delivery port 1102, thereby being able to seal the delivery port 1102.

[0109] As shown in Figures 2 and 3, in some examples, the width B1 of the first arcuate plate segment 122 is smaller than the width C1 of the first side groove segment 1103b, and when the cover body 120 covers the loading port 1102, an operating space 1202 is defined between the first arcuate plate segment 122 and the first side groove segment 1103b; the width of the second arcuate plate segment 123 is smaller than the width of the second side groove segment 1103c, and when the cover body 120 covers the loading port 1102, an operating space 1202 is defined between the second arcuate plate segment 123 and the second side groove segment 1103c.

[0110] In this technical solution, the width B1 of the first arc-shaped plate segment 122 can be set to be smaller than the width C1 of the first side groove segment 1103b, and the width of the second arc-shaped plate segment 123 can be set to be smaller than the width of the second side groove segment 1103c, so that when the cover body 120 covers the aforementioned delivery port 1102, the first arc-shaped plate segment 122 defines an operating space 1202 in the first side groove segment 1103b, and the second arc-shaped plate segment 123 defines an operating space 1202 in the second side groove segment 1103c, so that when the cover body 120 covers the delivery port 1102, the delivery unit 100 can have two operating spaces 1202, and the two operating spaces 1202 are respectively located in the cover body 120. 0 are at two ends that are away from each other, and thus, on the one hand, the spacing distance between the two operating ends 1201 can be expanded, and thus, while being convenient for the user to apply force to different parts of the cover body 120 at the same time, the force balance of the cover body 120 during use is further improved, which is beneficial to further reduce the probability of damage to the cover body 120 and improve the convenience of opening the delivery port 1102; on the other hand, it is also convenient for the user to operate the cover body 120 through the first arc-shaped plate segment 122 and the second arc-shaped plate segment 123 when performing the opening or covering operation of the delivery port 1102, and because the contours of the first arc-shaped plate segment 122 and the second arc-shaped plate segment 123 are relatively smooth and the number of angular structures is relatively small, it is more convenient for the user to operate.

[0111] As shown in FIG5 , in some examples, the thickness of the first curved plate segment 122 decreases along the direction from the main plate segment 121 to the first curved plate segment 122 ; the thickness of the second curved plate segment 123 decreases along the direction from the main plate segment 121 to the second curved plate segment 123 .

[0112] In this technical solution, the thickness of the first curved plate segment 122 can be set to decrease along the direction from the aforementioned main plate segment 121 to the aforementioned first curved plate segment 122. Correspondingly, the thickness of the second curved plate segment 123 can be set to decrease along the direction from the aforementioned main plate segment 121 to the aforementioned second curved plate segment 123. Therefore, based on the aforementioned setting, the parts of the first curved plate segment 122 and the second curved plate segment 123 away from the main plate segment 121 can have a thinner thickness, which is beneficial to further improve the operational convenience when the user manually opens and closes the delivery port 1102, and is beneficial to reducing the weight and volume of the cover body 120, reducing the overall production cost of the cover body 120 and the delivery unit 100, and is beneficial to further reduce the use cost of the delivery unit 100.

[0113] As shown in FIG. 1 and FIG. 2 , in some examples, the dispensing unit 100 further includes: a hinge portion 130 disposed between the cover portion 120 and the box portion 110 .

[0114] In this technical solution, the aforementioned dispensing unit 100 may also include a hinge portion 130 arranged between the aforementioned cover portion 120 and the aforementioned box body portion 110, so that the cover portion 120 can be hinged to the box body portion 110 through the hinge portion 130, so as to facilitate opening or covering the aforementioned liquid injection port by rotating relative to the cover portion 120, which is beneficial for ensuring the operational convenience of the dispensing unit 100 while ensuring the reliability of the connection between the box body portion 110 and the cover portion 120.

[0115] As shown in Figures 1 to 4 and Figures 6 to 8, in some examples, the hinge portion 130 includes: a connecting member 131, which is provided on the cover body 120, and the connecting member 131 is formed with an axis hole 1311; a rotating shaft 132, which is provided on the box body 110, and the rotating shaft 132 is rotatably passed through the axis hole 1311.

[0116] In this technical solution, the aforementioned hinged portion 130 may include a connecting member 131 and a rotating shaft 132, wherein the aforementioned connecting member 131 is arranged on the aforementioned cover portion 120 and is formed with an axis hole 1311, and the aforementioned rotating shaft 132 is arranged on the aforementioned box body portion 110 and can be rotatably passed through the connecting member 131 through the aforementioned axis hole 1311, so that based on the aforementioned setting, the box body portion 110 can be pivoted relative to the cover portion 120 to realize the opening and closing of the liquid injection port, and at the same time, it can avoid the structural complexity of the hinged portion 130 being too large, which is conducive to further reducing the production difficulty and manufacturing cost of the dosing unit 100, and thereby further reducing the use cost of the dosing unit 100.

[0117] As shown in Figures 3, 4, 6 to 8, in some feasible examples, the aforementioned rotating shaft 132 and the aforementioned box body 110 can be an integrated structure, and the aforementioned connecting member 131 and the aforementioned cover body 120 can be an integrated structure, which is beneficial to improve the assembly convenience of the box body 110, the cover body 120 and the hinged part 130, and improve the structural compactness of the delivery unit 100.

[0118] As shown in Figures 3, 4, 6 to 8, in some feasible examples, the number of the aforementioned rotating shafts 132 can be two, and the aforementioned two rotating shafts 132 are coaxially and relatively arranged on the aforementioned box body 110. It can be understood that, when the aforementioned rotating shaft 132 and the aforementioned box body 110 can be an integrated structure, the aforementioned rotating shaft 132 can be a cylindrical structure protruding from the box body 110; accordingly, the number of the aforementioned through-axis holes 1311 can also be two, and the two through-axis holes 1311 are respectively located on two sides of the connecting member 131 away from each other, and each of the aforementioned rotating shafts 132 is rotatably passed through a through-axis hole 1311; thus, based on the aforementioned arrangement, it is beneficial to further improve the smoothness of the rotation of the cover body 120 relative to the box body 110, and improve the connection reliability between the cover body 120 and the box body 110.

[0119] It is understandable that the aforementioned shaft hole 1311 can be a through hole or a blind hole opened in the aforementioned connecting member 131, which can match the aforementioned rotating shaft 132.

[0120] As shown in FIG. 4 and FIG. 6 to FIG. 8 , in some examples, the connecting member 131 has a notch 1312 , and the notch 1312 is located around the through-shaft hole 1311 and communicates with the through-shaft hole 1311 .

[0121] In this technical solution, the aforementioned connecting member 131 can be formed with a notch 1312 located on the circumferential side of the through-axis hole 1311, and the aforementioned notch 1312 is communicated with the aforementioned through-axis hole 1311. Therefore, based on the aforementioned setting, during the assembly process of the connecting member 131 and the rotating shaft 132, it is convenient for the rotating shaft 132 to pass through the aforementioned notch 1312 and into the through-axis hole 1311, which is conducive to further improving the assembly convenience of the hinged part 130, reducing the possibility of damage to the hinged part 130 during the assembly process, improving the production yield of the delivery unit 100, and helping to further reduce the use cost of the delivery unit 100.

[0122] As shown in Figures 3 and 7 to 9, in some examples, at least a portion of the circumferential wall of the rotating shaft 132 is an axial plane 1321, and the axial plane 1321 is parallel to the axial direction of the rotating shaft 132. The notch 1312 cooperates with the axial plane 1321 to make the rotating shaft 132 suitable for being inserted into the through-shaft hole 1311.

[0123] In this technical solution, at least part of the circumferential wall of the aforementioned rotating shaft 132 can be set as an axial plane 1321 parallel to the circumference of the rotating shaft 132, so that based on the aforementioned setting, the minimum radial dimension of the rotating shaft 132 can be reduced. During the assembly process of the connecting member 131 and the rotating shaft 132, the aforementioned rotating shaft 132 can utilize the aforementioned axial plane 1321 to cooperate with the mouth wall of the aforementioned notch 1312 to further facilitate the rotating shaft 132 to penetrate the aforementioned through-shaft hole 1311, which is beneficial to further improve the assembly convenience of the hinged part 130, reduce the possibility of damage to the hinged part 130 during the assembly process, and improve the production yield of the delivery unit 100.

[0124] As shown in Figure 9, for example, the chord length L of the aforementioned notch 1312 can be set to be smaller than the diameter of the rotating shaft 132 and approximately equal to the height H perpendicular to the axial plane 1321 in the cross section of the rotating shaft 132. In some embodiments, the aforementioned chord length L is slightly smaller than the aforementioned height H.

[0125] It is understood that, because the notch 1312 is located around and connected to the shaft hole 1311, the opening width of the notch 1312 can be represented by the chord length L of the shaft hole 1311 corresponding to the notch 1312. Accordingly, because the rotating shaft 132 is formed with the axial plane 1321, the relatively small radial dimension of the rotating shaft 132 can be represented by the height H of the cross section of the rotating shaft 132 perpendicular to the axial plane 1321. Therefore, the chord length L of the notch 1312 can be set to be approximately equal to the height H of the cross section of the rotating shaft 132 perpendicular to the axial plane 1321, preferably slightly smaller than the height H, to facilitate the rotating shaft 132 to pass through the notch 1312 into the shaft hole 1311. Furthermore, the chord length L of the notch 1312 can be set to be smaller than the diameter of the rotating shaft 132, thereby reducing the probability of the rotating shaft 132 slipping out of the shaft hole 1311 through the notch 1312 during rotation and ensuring the reliability of the hinge 130.

[0126] It can be understood that the number of the aforementioned axial planes 1321 can be greater than or equal to one. As shown in Figure 9, the number of the aforementioned axial planes 1321 can be two, and the two aforementioned axial planes 1321 are arranged parallel to each other on both sides, which is conducive to further reducing the minimum radial dimension of the rotating shaft 132 and facilitating the assembly of the rotating shaft 132.

[0127] It can be understood that when the number of axial planes 1321 is one, since the outer peripheral wall on the rotating shaft 132 opposite to the axial plane 1321 is an arc surface, the height H perpendicular to the axial plane 1321 in the cross section of the rotating shaft 132 is non-constant. Based on this situation, the chord length L of the aforementioned notch 1312 is approximately equal to the height H perpendicular to the axial plane 1321 in the cross section of the rotating shaft 132. The chord length L of the notch 1312 can be approximately equal to the maximum height H perpendicular to the axial plane 1321 in the cross section of the rotating shaft 132 to ensure the passability of the notch 1312.

Based on the aforementioned setting, in the process of manufacturing the aforementioned box body 110, the liquid storage box 111 and the box cover 112 can be processed independently, which is conducive to reducing the molding difficulty of the box body 110, improving the processing efficiency of the box body 110, and further helping to further reduce the use cost of the delivery unit 100.

[0130] It is understandable that, based on the above-mentioned configuration, in the process of manufacturing the box body 110 , different materials can be selected to manufacture the box cover 112 and the liquid storage box 111 in accordance with actual needs.

[0131] As shown in Figures 1 to 13, according to the second aspect of an embodiment of the present disclosure, a dispensing unit 100 is proposed, including: a box body 110, which is formed with a liquid storage cavity 1101 and a dispensing port 1102 connected to the liquid storage cavity 1101; a cover body 120, which is movably arranged on the box body 110, for covering or opening the dispensing port 1102, and the cover body 120 has the same width as the box body 110, and the cover body 120 has an operating end 1201.

[0132] The dispensing unit 100 provided in the embodiment of the present disclosure includes a box body 110 and a cover body 120, wherein the box body 110 is formed with a liquid storage cavity 1101 and a dispensing port 1102. In actual application, the liquid storage cavity 1101 can be used to accommodate cleaning agent, and the dispensing port 1102 is connected to the liquid storage cavity 1101, so that the user can inject cleaning agent into the liquid storage cavity 1101 through the dispensing port 1102; the cover body 120 is arranged on the box body 110 and can move relative to the box body 110, so as to The cover body 120 can cover or open the aforementioned liquid injection port by moving relative to the box body 110. When the cover body 120 covers the liquid injection port, the aforementioned liquid storage chamber 1101 and the external space can be separated from each other, thereby preventing substances in the external environment from entering the liquid storage chamber 1101, which is beneficial to ensuring the internal cleanliness of the liquid storage chamber 1101. When the cover body 120 opens the aforementioned liquid injection port, the aforementioned liquid storage chamber 1101 can be connected to the external space, thereby facilitating the filling of cleaning agent or the cleaning and maintenance of the liquid storage chamber 1101.

[0133] The aforementioned cover body 120 has an operating end 1201. In actual application, the aforementioned operating end 1201 can be used to withstand the driving force, which is the external force used to drive the cover body 120 to move relative to the box body 110 to realize the opening or closing of the liquid injection port. For example, when the user manually operates the cover body 120, the aforementioned operating end 1201 can be used to contact the operator's hand and withstand the driving force applied by the operator's hand; accordingly, when the aforementioned cover body 120 covers the aforementioned injection port 1102, an operating space 1202 is formed between the aforementioned operating end 1201 and the aforementioned box body 110. The aforementioned operating space 1202 can provide a passable space for the user's hand to approach and contact the aforementioned operating end 1201, thereby facilitating the user to operate the cover body 120.

[0134] At the same time, the width of the cover 120 is consistent with the width of the box body 110, which allows the cover 120 to have a relatively high width, thereby facilitating the user's hand to operate with a wider opening, thereby reducing the possibility of interference between the user's fingers during operation, and further improving the ease of operation of the cover 120. Accordingly, when the cover 120 is relatively large, the user can grasp the cover 120 to operate it, that is, the user can apply force to each operating end 1201 with two fingers, further improving the ease of operation of the cover 120.

[0135] It can be understood that the width of the aforementioned cover portion 120 is consistent with the width of the box body portion 110, that is, the cover portion 120 has a width similar to that of the box body portion 110 (for example, the same or slightly smaller width), and has an overall shape that is adapted to the box body portion 110 (for example: an overall shape consistent with the box body portion 110), thereby ensuring that the cover portion 120 has a higher width for user operation while making the dispensing unit 100 have a higher aesthetics.

[0136] For example, the width of the cover 120 can be greater than or equal to 0.8 times the width of the box body 110 and less than or equal to the width of the box body 110. This, on the one hand, allows the width of the box body 110 to be highly consistent with the width of the cover 120, thereby facilitating the user's hand-stretching operation and further improving the ease of operation of the cover 120. On the other hand, it also prevents the width of the cover 120 from being too large, thereby ensuring the compactness of the dispensing unit 100 and improving the aesthetics of the dispensing unit 100. For example, the width of the cover 120 can be, but is not limited to, 0.8 times, 0.85 times, 0.9 times, 0.9 times, 1 times, etc., of the width of the box body 110. The width ratio between the cover 120 and the box body 110 can be set according to actual needs and is not further limited here.

[0137] It can be understood that, when the cover portion 120 is a plate-like structure, the operating end 1201 can be a plate end in the width direction of the plate-like structure.

[0138] It should be noted that some conventional dispensing units 100 typically include a box body and multiple covers. The box body has multiple open liquid storage spaces, and the covers are used to cover or open the openings of the aforementioned liquid storage spaces one by one. As a result, the size of the covers is often smaller than the box body, and the box body typically has a small notch structure on one side corresponding to the cover. When the cover covers the aforementioned opening, if the user needs to open the aforementioned opening, they can only insert a single fingernail through the aforementioned small notch structure on the side of the cover. This is not only difficult to operate and has a poor user experience, but also, due to the cramped space, it is not easy for the user to control the direction and magnitude of the force applied, which can easily cause damage to the cover. Based on the above-mentioned configuration, the dispensing unit 100 provided in the embodiment of the present disclosure can increase the width of the cover portion 120, thereby facilitating the contact area between the cover portion 120 and the user's hand, making it easier for the user to apply force during operation, thereby reducing the chance of damage to the cover portion 120 in actual use.

[0139] It should be noted that, in actual applications, the dispensing unit 100 provided in the embodiment of the present disclosure can be used as a component of a cleaning device, and the aforementioned cleaning device can be, but is not limited to, a washing machine, a dishwasher, a sweeping robot, etc. Accordingly, the aforementioned cleaning agent can be, but is not limited to, laundry liquid, softener, detergent, washing powder, disinfectant, etc. Taking the application of the aforementioned dispensing unit 100 to a washing machine as an example, the aforementioned box body 110 can be set in the casing of the washing machine, and the aforementioned liquid storage chamber 1101 can be used to store detergents such as laundry liquid and softener. The liquid storage chamber 1101 of the aforementioned dispensing unit 100 can be used to connect to the detergent dispensing flow path of the washing machine. It can be understood that the output end of the aforementioned detergent dispensing flow path is connected to the clothes processing chamber of the washing machine, so that during the process of washing clothes, the detergent in the dispensing unit 100 can be dispensed into the clothes processing chamber through the detergent dispensing flow path to participate in the clothes washing operation.

[0140] In some feasible examples, the number of the aforementioned operating ends 1201 is at least two, and when the cover body 120 covers the injection port 1102, an operating space 1202 is formed between each operating end 1201 and the box body 110, so that the user's hand can contact multiple parts of the cover body 120 at the same time (for example: opposite sides, which is convenient for the user to hold), and the aforementioned driving force can be applied to multiple parts of the cover body 120 at the same time, so that during the operation of switching the injection port from a covered state to an open state, on the one hand, it can be beneficial to increase the contact area between the cover body 120 and the user's hand, expand the feasible contact orientation between the cover body 120 and the user's hand, thereby improving the user's force application convenience during the operation, reducing the difficulty of opening the injection port 1102, and improving the product experience; on the other hand, it is also beneficial to prevent the cover body 120 from being subjected to a more concentrated driving force, improve the force dispersion and balance of the cover body 120, thereby reducing the probability of damage to the cover body 120 in actual application, and reducing the maintenance and use costs of the injection unit 100.

[0141] It can be understood that the at least two operating ends 1201 can be at least two different ends of the cover body 120 , and the at least two operating ends 1201 can be adjacent to each other or spaced apart from each other.

[0142] For example, as shown in FIG4 , the cover body 120 can be a generally rectangular plate-like structure (in some embodiments, the cover body 120 is a square plate-like structure), so that the cover body 120 has four ends in the length and width directions. Thus, for the cover body 120 with a rectangular plate-like structure, the number of the aforementioned operating ends 1201 can be greater than or equal to two and less than or equal to four. Taking into account the connection between the cover body 120 and the box body 110, the number of operating ends 1201 of the cover body 120 with a rectangular plate-like structure can be less than or equal to three, that is, in actual application, one end of the cover body 120 in the length or width direction can be used to connect to the box body 110. It can be understood that the shape of the cover body 120 can be, but is not limited to, a rectangular plate-like structure, and can also be other polygonal plate-like structures, such as a triangular plate-like structure, a pentagonal plate-like structure, a hexagonal plate-like structure, etc. Accordingly, the number of operating ends 1201 can also be set in combination with the shape of the cover body 120 and actual needs.

[0143] In some feasible examples, the aforementioned operating end 1201 may be provided with anti-slip grooves to further facilitate the user to apply force to the cover body 120.

[0144] In some feasible examples, the length of the aforementioned operating space 1202 is greater than or equal to the length of the aforementioned operating end 1201, so that the operating space 1202 can correspond to the entire side of the cover body 120, expand the distribution range of the operating space 1202, and further improve the operating convenience of the cover body 120. It can be understood that the length of the aforementioned operating end 1201 is also the dimension of the operating end 1201 in the extension direction. Taking the case where the cover body 120 is a rectangular plate structure as an example, if the aforementioned operating end 1201 is one end in the length direction of the rectangular plate structure, then the operating end 1201 corresponds to the long side of the rectangular plate structure. Accordingly, the operating end 1201 extends along the length direction of the rectangular plate structure. Similarly, if the operating end 1201 is one end in the length direction of the rectangular plate structure, then the operating end 1201 extends along the width direction of the rectangular plate structure. Accordingly, the length direction of the aforementioned operating space 1202 is consistent with the length direction of the aforementioned operating end 1201.

[0145] As shown in FIG. 1 , FIG. 2 , FIG. 4 and FIG. 5 , in some examples, there are two operating ends 1201 , and the two operating ends 1201 face away from each other.

[0146] In this technical solution, the number of the aforementioned operating ends 1201 can be two, and the two aforementioned operating ends 1201 are separated from each other, that is, the two ends of the cover body 120 that are separated from each other can serve as the aforementioned two operating ends 1201. Based on the aforementioned setting, the spacing distance between the aforementioned two operating ends 1201 can be expanded, and then while being able to facilitate the user to apply force to different parts of the cover body 120 at the same time, the force balance of the cover body 120 during use is further improved, which is beneficial to further reduce the chance of damage to the cover body 120 and improve the convenience of opening the injection port 1102.

[0147] It is understandable that, when the two operating ends 1201 face away from each other, when the cover 120 covers the aforementioned delivery port 1102 , two operating spaces 1202 will be correspondingly formed between the cover 120 and the box body 110 .

[0148] As shown in Figures 1 to 3, in some examples, the box body 110 is formed with a groove 1103, and the delivery port 1102 is arranged in the groove 1103. When the cover body 120 covers the delivery port 1102, the cover body 120 is located in the groove 1103, and an operating space 1202 is defined in the groove 1103.

[0149] In this technical solution, the box body 110 may be formed with a groove 1103, and the delivery port 1102 may be formed in the groove 1103, that is, the groove 1103 and the liquid storage chamber 1101 may be arranged adjacent to each other and communicate with each other. When the cover 120 covers the delivery port 1102, the cover 120 is located in the groove 1103 and defines the operating space 1202 in the groove 1103, thereby avoiding the cover 120 from protruding from the box body 110, improving the structural concealment of the cover 120 when covering the delivery port 1102, and thus improving the aesthetics of the delivery unit 100 and further enhancing the user experience of the product. On the other hand, it can also reduce the possibility of external structures contacting the cover 120, reduce the probability of the delivery port 1102 being accidentally opened, and help to further avoid damage to the cover 120, providing further protection for reducing the use cost of the delivery unit 100.

[0150] As shown in Figures 1 to 3, in some feasible examples, the portion of the box body 110 corresponding to the operating end 1201 may be formed with an opening, and the opening is connected to the groove 1103. Accordingly, when the cover body 120 covers the delivery port 1102, the opening is connected to the operating space 1202, thereby facilitating the passability of the operating space 1202, and further facilitating the user's hand to contact the operating end 1201 of the cover body 120 through the operating space 1202, thereby further improving the convenience of the opening operation of the delivery port 1102.

[0151] As shown in Figures 1 to 3, in some examples, the loading port 1102 is formed on the bottom wall of the groove 1103. When the cover 120 covers the loading port 1102, the side of the cover 120 away from the loading port 1102 is flush with the side of the box body 110.

[0152] In this technical solution, the aforementioned delivery port 1102 can be formed on the bottom wall of the aforementioned groove 1103. It can be understood that The aforementioned groove 1103 is an open groove, and the bottom wall of the aforementioned groove 1103 is also the aforementioned groove wall opposite to the aforementioned groove. When the aforementioned cover body 120 covers the aforementioned delivery port 1102, one side of the cover body 120 can abut against the bottom wall of the aforementioned groove 1103 to achieve coverage of the aforementioned delivery port 1102. Accordingly, the side of the cover body 120 away from the delivery port 1102 can be set to be flush with the side of the box body 110, for example, flush with the side of the box body 110 where the aforementioned groove 1103 is formed. Then, when the aforementioned cover body 120 covers the aforementioned delivery port 1102, the side of the delivery unit 100 where the aforementioned cover body 120 is provided can have a higher surface flatness, which is beneficial to improving the shape matching between the cover body 120 and the groove 1103, further improving the aesthetics of the delivery unit 100, and on the other hand, it is beneficial to further improve the structural compactness of the delivery unit 100 and improve the miniaturization level of the delivery unit 100.

[0153] It can be understood that by opening the aforementioned delivery port 1102 on the bottom wall of the aforementioned groove 1103, the aforementioned delivery port 1102 can also be directed towards the notch of the aforementioned groove 1103, so that when the cover body 120 opens the aforementioned delivery port 1102, it can be further convenient for the operator to inject the cleaning agent into the aforementioned delivery port 1102, which is conducive to further improving the ease of use of the delivery unit 100.

[0154] As shown in Figures 1 to 8, in some examples, the cover body 120 includes a main plate segment 121, a first curved plate segment 122 and a second curved plate segment 123, and the main plate segment 121 is connected between the first curved plate segment 122 and the second curved plate segment 123; the groove 1103 includes a main groove segment 1103a, a first side groove segment 1103b and a second side groove segment 1103c, and the main groove segment 1103a is located between the first side groove segment 1103b and the second side groove segment 1103c; wherein, the shape of the main plate segment 121 is adapted to the shape of the main groove segment 1103a, and the first curved plate segment 122 and the second curved plate segment 123 are respectively consistent with the curvature at the corresponding positions of the box body 110.

[0155] In this technical solution, the aforementioned cover body 120 may include a first arc-shaped plate segment 122, a main body plate segment 121 and a second arc-shaped plate segment 123 connected in sequence. Correspondingly, the aforementioned groove 1103 may include a first side groove segment 1103b, a main body groove segment 1103a and a second side groove segment 1103c connected in sequence. The aforementioned first arc-shaped plate segment 122, the main body plate segment 121 and the second arc-shaped plate segment 123 correspond to the aforementioned first side groove segment 1103b, the main body groove segment 1103a and the second side groove segment 1103c, respectively. That is, when the aforementioned cover body 120 covers the aforementioned loading port 1102, the first arc-shaped plate segment 122 is located in the aforementioned first side groove segment 1103b, and the main body plate segment 121 is located in the aforementioned 21 is located in the main groove section 1103a, and the second arc-shaped plate section 123 is located in the second side groove section 1103c. It can be understood that the aforementioned delivery port 1102 can be opened on the bottom wall of the aforementioned main groove section 1103a. Accordingly, the cover body 120 can use the main plate section 121 to cover or open the aforementioned delivery port 1102, and based on the aforementioned setting, both ends of the main plate section 121 are arc-shaped plate sections, so that the contour of the outer edge of the cover body 120 can be smoother, which is conducive to reducing the angular structure of the edge of the cover body 120, reducing the risk of scratches when the user operates, further improving the convenience of opening and closing the delivery port 1102, and helping to further improve the aesthetics of the delivery unit 100.

[0156] Among them, the shape of the main plate section 121 can be adapted to the shape of the main groove section 1103a, so that when the cover body 120 covers the delivery port 1102, the main plate section 121 and the main groove section 1103a can be more fitted together, making it convenient to make the main plate section 121 and the corresponding partial groove openings of the main groove section 1103a flush, and reduce the fitting gap between the main plate section 121 and the main groove section 1103a, which is beneficial to improve the aesthetics of the delivery unit 100 while reducing the risk of liquid overflow.

[0157] At the same time, the first curved plate segment 122 and the second curved plate segment 123 can be set to be consistent with the curvature of the corresponding position of the box body 110. It should be noted that the position corresponding to the aforementioned box body 110 and the aforementioned first curved plate segment 122 includes the first side groove segment 1103b, so that the aforementioned first side groove segment 1103b can be a curved groove segment; the position corresponding to the aforementioned box body 110 and the aforementioned first curved plate segment 122 includes the second side groove segment 1103c, so that the aforementioned second side groove segment 1103c can also be a curved groove segment; and based on the aforementioned setting, each curved plate segment and the corresponding side groove segment can have a curvature with a high degree of matching, which is conducive to making each curved plate segment more fit against the groove wall of the corresponding side groove segment when the cover body 120 covers the delivery port 1102, thereby reducing the matching gap between the curved plate segment and the corresponding side groove segment, which is conducive to further improving the aesthetics of the delivery unit 100 while reducing the risk of liquid overflow.

[0158] For example, as shown in Figures 2, 3 and 5, the aforementioned delivery port 1102 is formed on the bottom wall of the main groove section 1103a. The bottom wall of the aforementioned main groove section 1103a can be a plane. Correspondingly, the main plate section 121 can be a plate-like structure with high flatness, so that the main groove section 1103a and the main plate section 121 can be matched; the bottom walls of the first side groove section 1103b and the second side groove section 1103c are inclined from the inside to the outside, and can also be arc-shaped walls, and smoothly transition with the bottom wall of the main groove section 1103a, thereby increasing the operating space 1202 of the user's fingers and improving the smoothness of the groove wall of the groove 1103, which is conducive to reducing the angular structure of the groove wall of the groove 1103. Improve the cleaning convenience and aesthetics of the groove 1103; the aforementioned curved wall surface can be a convex curved surface, that is, the aforementioned curved wall surface is a curved surface that is convex toward the space in the groove, and the aforementioned first curved plate segment 122 is used to match the plate surface of the bottom wall of the first side groove segment 1103b can be a concave curved surface, and the aforementioned second curved plate segment 123 is used to match the plate surface of the bottom wall of the second side groove segment 1103c can also be a concave curved surface, so that each curved plate segment can adapt to the corresponding side groove segment, and can accordingly make the first curved plate segment 122 and the second curved plate segment 123 facing away from the side of the delivery port 1102 to be convex curved surface, which is beneficial to improve the aesthetics of the cover body 120 while ensuring the ease of operation of the cover body 120.

[0159] As shown in FIG. 1 to FIG. 3 , FIG. 7 and FIG. 8 , in some feasible examples, the cover portion 120 and the box body portion 110 have a consistent overall shape. For example, the side of the box body 110 on which the groove 1103 is formed may also have a main decorative surface 1104, a first side decorative surface 1105 and a second side decorative surface 1106, and the main decorative surface 1104, the first side decorative surface 1105 and the second side decorative surface 1106 are all located on the groove periphery of the groove 1103, and the main decorative surface 1104 corresponds to the main groove section 1103a, the first side decorative surface 1105 corresponds to the first side groove section 1103b, and the second side decorative surface 1106 corresponds to the second side groove section 1103c; accordingly, the position of the box body 110 corresponding to the first curved plate section 122 also includes the first side decorative surface 1105, and the position of the box body 110 corresponding to the second curved plate section 123 also includes the second side decorative surface 1106, that is, the first side decorative surface 1105 corresponds to the second side decorative surface 1106 can both be curved surfaces, and the curvature of the aforementioned first side finishing surface 1105 and the curvature of the aforementioned second side finishing surface 1106 are respectively consistent with the curvature of the aforementioned first curved plate segment 122 and the curvature of the aforementioned second curved plate segment 123; when the cover body 120 covers the aforementioned delivery port 1102, the side of the first curved plate segment 122 facing away from the delivery port 1102 is flush with the first side finishing surface 1105, the side of the second curved plate segment 123 facing away from the delivery port 1102 is flush with the second side finishing surface 1106, and the side of the main plate segment 121 facing away from the delivery port 1102 is flush with the main finishing surface 1104. Based on the above-mentioned setting, when the cover body 120 covers the aforementioned delivery port 1102, the side of the delivery unit 100 provided with the aforementioned cover body 120 can have a higher surface flatness, which is conducive to further improving the aesthetics of the delivery unit 100.

[0160] As shown in Figures 1 to 8, in some feasible examples, the edge of the groove 1103 can have multiple rounded transition structures, and accordingly, the edge of the cover body 120 can also have multiple rounded transition structures, which is conducive to further reducing the sharp corners of the groove 1103 and the cover plate, thereby helping to improve the aesthetics of the delivery unit 100 while ensuring the safety of operation.

[0161] In some feasible examples, the first arc-shaped plate segment 122 , the main body plate segment 121 and the second arc-shaped plate segment 123 are an integrated structure.

[0162] As shown in Figures 4 to 6, in some feasible examples, the aforementioned cover body 120 may also include a delivery plug 124, which is arranged on one side of the aforementioned main plate section 121 and includes a raised plug frame and a sealing ring, which is used to removably close the aforementioned delivery port 1102. When the cover body 120 covers the delivery port 1102, the delivery plug 124 is inserted into the aforementioned delivery port 1102, thereby being able to seal the delivery port 1102.

[0163] As shown in Figures 2 and 3, in some examples, the width B1 of the first arcuate plate segment 122 is smaller than the width C1 of the first side groove segment 1103b, and when the cover body 120 covers the loading port 1102, an operating space 1202 is defined between the first arcuate plate segment 122 and the first side groove segment 1103b; the width of the second arcuate plate segment 123 is smaller than the width of the second side groove segment 1103c, and when the cover body 120 covers the loading port 1102, an operating space 1202 is defined between the second arcuate plate segment 123 and the second side groove segment 1103c.

[0164] In this technical solution, the width B1 of the first arc-shaped plate segment 122 can be set to be smaller than the width C1 of the first side groove segment 1103b, and the width of the second arc-shaped plate segment 123 can be set to be smaller than the width of the second side groove segment 1103c, so that when the cover body 120 covers the aforementioned delivery port 1102, the first arc-shaped plate segment 122 defines an operating space 1202 in the first side groove segment 1103b, and the second arc-shaped plate segment 123 defines an operating space 1202 in the second side groove segment 1103c, so that when the cover body 120 covers the delivery port 1102, the delivery unit 100 can have two operating spaces 1202, and the two operating spaces 1202 are respectively located in the cover body 120. 0 are at two ends that are away from each other, and thus, on the one hand, the spacing distance between the two operating ends 1201 can be expanded, and thus, while being convenient for the user to apply force to different parts of the cover body 120 at the same time, the force balance of the cover body 120 during use is further improved, which is beneficial to further reduce the probability of damage to the cover body 120 and improve the convenience of opening the delivery port 1102; on the other hand, it is also convenient for the user to operate the cover body 120 through the first arc-shaped plate segment 122 and the second arc-shaped plate segment 123 when performing the opening or covering operation of the delivery port 1102, and because the contours of the first arc-shaped plate segment 122 and the second arc-shaped plate segment 123 are relatively smooth and the number of angular structures is relatively small, it is more convenient for the user to operate.

[0165] As shown in FIG5 , in some examples, the thickness of the first curved plate segment 122 decreases along the direction from the main plate segment 121 to the first curved plate segment 122 ; the thickness of the second curved plate segment 123 decreases along the direction from the main plate segment 121 to the second curved plate segment 123 .

[0166] In this technical solution, the thickness of the first curved plate segment 122 can be set to decrease along the direction from the aforementioned main plate segment 121 to the aforementioned first curved plate segment 122. Correspondingly, the thickness of the second curved plate segment 123 can be set to decrease along the direction from the aforementioned main plate segment 121 to the aforementioned second curved plate segment 123. Therefore, based on the aforementioned setting, the parts of the first curved plate segment 122 and the second curved plate segment 123 away from the main plate segment 121 can have a thinner thickness, which is beneficial to further improve the operational convenience when the user manually opens and closes the delivery port 1102, and is beneficial to reducing the weight and volume of the cover body 120, reducing the overall production cost of the cover body 120 and the delivery unit 100, and is beneficial to further reduce the use cost of the delivery unit 100.

[0167] As shown in FIG. 1 and FIG. 2 , in some examples, the dispensing unit 100 further includes: a hinge portion 130 disposed between the cover portion 120 and the box portion 110 .

[0168] In this technical solution, the aforementioned dispensing unit 100 may also include a hinge portion 130 arranged between the aforementioned cover portion 120 and the aforementioned box body portion 110, so that the cover portion 120 can be hinged to the box body portion 110 through the hinge portion 130, so as to facilitate opening or covering the aforementioned liquid injection port by rotating relative to the cover portion 120, which is beneficial for ensuring the operational convenience of the dispensing unit 100 while ensuring the reliability of the connection between the box body portion 110 and the cover portion 120.

[0169] As shown in Figures 1 to 4 and Figures 6 to 8, in some examples, the hinge portion 130 includes: a connecting member 131, which is provided on the cover body 120, and the connecting member 131 is formed with an axis hole 1311; a rotating shaft 132, which is provided on the box body 110, and the rotating shaft 132 is rotatably passed through the axis hole 1311.

[0170] In this technical solution, the aforementioned hinged portion 130 may include a connecting member 131 and a rotating shaft 132, wherein the aforementioned connecting member 131 is arranged on the aforementioned cover portion 120 and is formed with an axis hole 1311, and the aforementioned rotating shaft 132 is arranged on the aforementioned box body portion 110 and can be rotatably passed through the connecting member 131 through the aforementioned axis hole 1311, so that based on the aforementioned setting, the box body portion 110 can be pivoted relative to the cover portion 120 to realize the opening and closing of the liquid injection port, and at the same time, it can avoid the structural complexity of the hinged portion 130 being too large, which is conducive to further reducing the production difficulty and manufacturing cost of the dosing unit 100, and thereby further reducing the use cost of the dosing unit 100.

[0171] As shown in Figures 3, 4, 6 to 8, in some feasible examples, the aforementioned rotating shaft 132 and the aforementioned box body 110 can be an integrated structure, and the aforementioned connecting member 131 and the aforementioned cover body 120 can be an integrated structure, which is beneficial to improve the assembly convenience of the box body 110, the cover body 120 and the hinged part 130, and improve the structural compactness of the delivery unit 100.

[0172] As shown in Figures 3, 4, 6 to 8, in some feasible examples, the number of the aforementioned rotating shafts 132 can be two, and the aforementioned two rotating shafts 132 are coaxially and relatively arranged on the aforementioned box body 110. It can be understood that, when the aforementioned rotating shaft 132 and the aforementioned box body 110 can be an integrated structure, the aforementioned rotating shaft 132 can be a cylindrical structure protruding from the box body 110; accordingly, the number of the aforementioned through-axis holes 1311 can also be two, and the two through-axis holes 1311 are respectively located on two sides of the connecting member 131 away from each other, and each of the aforementioned rotating shafts 132 is rotatably passed through a through-axis hole 1311; thus, based on the aforementioned arrangement, it is beneficial to further improve the smoothness of the rotation of the cover body 120 relative to the box body 110, and improve the connection reliability between the cover body 120 and the box body 110.

[0173] It is understandable that the aforementioned shaft hole 1311 can be a through hole or a blind hole opened in the aforementioned connecting member 131, which can match the aforementioned rotating shaft 132.

[0174] As shown in FIG. 4 and FIG. 6 to FIG. 8 , in some examples, the connecting member 131 has a notch 1312 , and the notch 1312 is located around the through-shaft hole 1311 and communicates with the through-shaft hole 1311 .

[0175] In this technical solution, the aforementioned connecting member 131 can be formed with a notch 1312 located on the circumferential side of the through-axis hole 1311, and the aforementioned notch 1312 is communicated with the aforementioned through-axis hole 1311. Therefore, based on the aforementioned setting, during the assembly process of the connecting member 131 and the rotating shaft 132, it is convenient for the rotating shaft 132 to pass through the aforementioned notch 1312 and into the through-axis hole 1311, which is conducive to further improving the assembly convenience of the hinged part 130, reducing the possibility of damage to the hinged part 130 during the assembly process, improving the production yield of the delivery unit 100, and helping to further reduce the use cost of the delivery unit 100.

[0176] As shown in Figures 3 and 7 to 9, in some examples, at least a portion of the circumferential wall of the rotating shaft 132 is an axial plane 1321, and the axial plane 1321 is parallel to the axial direction of the rotating shaft 132. The notch 1312 cooperates with the axial plane 1321 to make the rotating shaft 132 suitable for being inserted into the through-shaft hole 1311.

[0177] In this technical solution, at least part of the circumferential wall of the aforementioned rotating shaft 132 can be set as an axial plane 1321 parallel to the circumference of the rotating shaft 132, so that based on the aforementioned setting, the minimum radial dimension of the rotating shaft 132 can be reduced. During the assembly process of the connecting member 131 and the rotating shaft 132, the aforementioned rotating shaft 132 can utilize the aforementioned axial plane 1321 to cooperate with the mouth wall of the aforementioned notch 1312 to further facilitate the rotating shaft 132 to penetrate the aforementioned through-shaft hole 1311, which is beneficial to further improve the assembly convenience of the hinged part 130, reduce the possibility of damage to the hinged part 130 during the assembly process, and improve the production yield of the delivery unit 100.

[0178] As shown in Figure 9, for example, the chord length L of the aforementioned notch 1312 can be set to be smaller than the diameter of the rotating shaft 132 and approximately equal to the height H perpendicular to the axial plane 1321 in the cross section of the rotating shaft 132. In some embodiments, the aforementioned chord length L is slightly smaller than the aforementioned height H.

[0179] It is understood that, because the notch 1312 is located around and connected to the shaft hole 1311, the opening width of the notch 1312 can be represented by the chord length L of the shaft hole 1311 corresponding to the notch 1312. Accordingly, because the rotating shaft 132 is formed with the axial plane 1321, the relatively small radial dimension of the rotating shaft 132 can be represented by the height H of the cross section of the rotating shaft 132 perpendicular to the axial plane 1321. Therefore, the chord length L of the notch 1312 can be set to be approximately equal to the height H of the cross section of the rotating shaft 132 perpendicular to the axial plane 1321, preferably slightly smaller than the height H, to facilitate the rotating shaft 132 to pass through the notch 1312 into the shaft hole 1311. Furthermore, the chord length L of the notch 1312 can be set to be smaller than the diameter of the rotating shaft 132, thereby reducing the probability of the rotating shaft 132 slipping out of the shaft hole 1311 through the notch 1312 during rotation and ensuring the reliability of the hinge 130.

[0180] It can be understood that the number of the aforementioned axial planes 1321 can be greater than or equal to one. As shown in Figure 9, the number of the aforementioned axial planes 1321 can be two, and the two aforementioned axial planes 1321 are arranged parallel to each other on both sides, which is conducive to further reducing the minimum radial dimension of the rotating shaft 132 and facilitating the assembly of the rotating shaft 132.

[0181] It can be understood that when the number of axial planes 1321 is one, since the outer peripheral wall on the rotating shaft 132 opposite to the axial plane 1321 is an arc surface, the height H perpendicular to the axial plane 1321 in the cross section of the rotating shaft 132 is non-constant. Based on this situation, the chord length L of the aforementioned notch 1312 is approximately equal to the height H perpendicular to the axial plane 1321 in the cross section of the rotating shaft 132. The chord length L of the notch 1312 can be approximately equal to the maximum height H perpendicular to the axial plane 1321 in the cross section of the rotating shaft 132 to ensure the passability of the notch 1312.

[0182] As shown in FIG. 1 to FIG. 3 , FIG. 7 and FIG. 8 , in some examples, the box body 110 includes: a liquid storage box 111 , forming a liquid storage cavity 1101 ; and a box cover 112 , disposed on the liquid storage box 111 , forming a delivery port 1102 .

[0183] In this technical solution, the aforementioned box body 110 may include a liquid storage box 111 and a box cover 112 that are connected to each other, wherein the aforementioned liquid storage cavity 1101 is formed in the aforementioned liquid storage box 111, and the aforementioned delivery port 1102 is formed in the aforementioned box cover 112. Based on the aforementioned setting, in the process of manufacturing the aforementioned box body 110, the liquid storage box 111 and the box cover 112 can be processed independently, which is conducive to reducing the molding difficulty of the box body 110, improving the processing efficiency of the box body 110, and further helping to further reduce the use cost of the delivery unit 100.

[0184] It is understandable that, based on the above-mentioned configuration, in the process of manufacturing the box body 110 , different materials can be selected to manufacture the box cover 112 and the liquid storage box 111 in accordance with actual needs.

[0185] As shown in Figures 10 to 13, according to the third aspect of an embodiment of the present disclosure, a cleaning device is proposed, including: a dispensing unit 100 as proposed in any one of the first or second aspects above; a pumping unit 200, connected to the liquid storage chamber 1101; and / or a liquid quantity detection unit 300, for detecting the remaining liquid in the liquid storage chamber 1101.

[0186] The dispensing system 10 provided in the embodiment of the present disclosure includes the dispensing unit 100 proposed in any one of the first aspects above, so that when the dispensing system 10 participates in the cleaning operation of the object to be cleaned, the aforementioned dispensing unit 100 can be used to store the cleaning agent, which is beneficial to ensure the cleaning effect and ease of use of the cleaning equipment.

[0187] Meanwhile, as shown in FIG. 10 to FIG. 12 , the delivery system 10 may further include a pumping unit 200 . The pumping unit 200 is connected to the liquid storage chamber 1101 of the delivery unit 100 and is used to discharge the fluid in the delivery chamber.

[0188] It is understood that the dispensing system 10 provided by the embodiment of the present disclosure can be applied to, but not limited to, clothing processing equipment such as washing machines and washer-dryers, or cleaning equipment such as dishwashers and sweeping robots in actual applications. Accordingly, the aforementioned cleaning agent can be, but not limited to, laundry liquid, softener, detergent, disinfectant, etc. Taking the application of the aforementioned dispensing system 10 to a washing machine as an example, the washing machine generally has a cleaning agent dispensing flow path and a clothing processing chamber. The liquid storage chamber 1101 of the aforementioned dispensing unit 100 can be connected to the aforementioned cleaning agent dispensing flow path through the aforementioned pumping unit 200, so that the cleaning agent in the liquid storage chamber 1101 can be output to the aforementioned cleaning agent dispensing flow path through the pumping unit 200. It is understood that the output end of the aforementioned cleaning agent dispensing flow path is connected to the aforementioned clothing processing chamber, so that during the process of washing clothes, the cleaning agent in the dispensing unit 100 can be dispensed into the clothing processing chamber through the cleaning agent dispensing flow path to participate in the clothing washing operation.

[0189] Alternatively, as shown in FIG12 , the aforementioned dispensing system 10 may further include a liquid quantity detection unit 300 , which is used to detect the remaining liquid in the liquid storage chamber 1101 , thereby facilitating the user to understand the amount of detergent dispensed during use, thereby further improving the ease of use of the dispensing system 10 .

[0190] It is understandable that the aforementioned dosing system 10 may include the aforementioned pumping unit 200 and the aforementioned liquid quantity detection unit 300 at the same time.

[0191] As shown in Figures 10 to 13, in some examples, the aforementioned cleaning device also includes: a accommodating unit 400, which is formed with an open accommodating cavity 401 and a first limiting structure 402, and the box body 110 can be pulled out or pushed into the accommodating cavity 401, and the dispensing unit 100 also includes a decorative panel portion 140 and a second limiting structure 150, and the second limiting structure 150 is detachably connected to the first limiting structure 402; wherein, when the box body portion 110 is pushed into the accommodating cavity 401, the second limiting structure 150 is connected to the first limiting structure 402, and the decorative panel portion 140 covers the opening of the accommodating cavity 401.

[0192] In this technical solution, the dispensing system 10 may further include a accommodating unit 400, wherein the accommodating unit 400 forms an open accommodating cavity 401; the dispensing unit 100 may further include a decorative panel portion 140, wherein the box body portion 110 is movably connected to the accommodating unit 400 so that the box body portion 110 can be pulled out or pushed into the accommodating cavity 401; when the box body portion 110 is pushed into the accommodating cavity 401, the decorative panel portion 140 covers the opening of the accommodating cavity 401, thereby facilitating further improving the aesthetics and structural compactness of the cleaning equipment.

[0193] As shown in Figures 12 and 13, the aforementioned accommodating unit 400 can be formed with a first limiting structure 402, and the aforementioned delivery unit 100 can also include a second limiting structure 150. When the box body 110 is pushed into the accommodating cavity 401, the second limiting structure 150 is connected to the first limiting structure 402, so that the delivery system 10 can fix the relative position between the accommodating unit 400 and the delivery unit 100 based on the matching relationship between the aforementioned first limiting structure 402 and the aforementioned second limiting structure 150, thereby reducing the possibility of the delivery unit 100 accidentally falling out of the accommodating unit 400 during use.

[0194] It is understood that the accommodating unit 400 can be used to fix the housing assembly 20 disposed on the cleaning device (for example, a clothes processing device). It is understood that the housing assembly 20 can include a base 21 and a panel 22.

[0195] As shown in Figures 12 and 13, in some feasible examples, the aforementioned first limiting structure 402 can be a fixed column, and the aforementioned second limiting structure 150 can be a buckle, and the aforementioned buckle can be detachably connected to the aforementioned fixed column, so that the first limiting structure 402 and the second limiting structure 150 can be fixed by snapping.

[0196] It should be noted that, in actual applications, the aforementioned accommodating unit 400 may be disposed in the housing of the cleaning device, or may also be integrally formed in the housing of the aforementioned cleaning device.

[0197] As shown in Figure 12, in some feasible examples, the aforementioned liquid quantity detection unit 300 may include a magnetic levitation 310, and the dispensing unit 100 also includes a mounting column 160. The mounting column 160 is located in the liquid storage chamber 1101 and is arranged along the depth direction of the liquid storage chamber 1101. The magnetic levitation 310 is movably mounted on the mounting column 160. Based on the aforementioned setting, the range of movement of the aforementioned magnetic levitation 310 can be constrained to ensure the smooth operation of the magnetic levitation 310.

[0198] It can be understood that when the liquid quantity detection unit 300 includes the aforementioned magnetic levitation 310, the liquid quantity detection unit 300 is also a magnetic levitation 310 type liquid level sensor. Accordingly, when there is liquid in the liquid storage chamber 1101, the magnetic levitation 310 will float on the liquid and rise and fall with the change of liquid level. Accordingly, the magnetic levitation 310 type liquid level sensor can also include components such as magnetic switches for sensing the position of the magnetic levitation 310, and processing components that convert the aforementioned position into liquid quantity information, thereby obtaining the remaining liquid in the liquid storage chamber 1101.

[0199] As shown in Figures 14 to 16, in some feasible examples, when the dispensing system 10 is applied to a clothing processing device, the accommodating unit 400 is arranged close to the cleaning port 23 of the clothing processing device, and when the box body 110 is retracted into the accommodating cavity 401, the decorative panel portion 140 covers the opening of the accommodating cavity 401 and the cleaning port 23.

[0200] In this technical solution, when the delivery system 10 is applied to a clothing processing device, the aforementioned accommodating unit 400 can be arranged close to the cleaning port 23 of the clothing processing device. It can be understood that the clothing processing device usually has a drainage system or a filtration system 40. Accordingly, a cleaning port 23 corresponding to the cleaning end 41 of the aforementioned drainage system or filtration system 40 will be provided on the housing assembly 20 of the clothing processing device, so that the user can regularly clean the drainage system or filtration system 40 to reduce the chance of blockage of components or pipes. The accommodating unit 400 provided in the embodiment of the present disclosure can be arranged close to the cleaning port 23 of the clothing processing device. Accordingly, when the box body 110 of the dispensing unit 100 is retracted into the accommodating cavity 401 of the accommodating unit 400, the decorative panel portion 140 of the dispensing unit 100 can be arranged to cover the opening of the accommodating cavity 401 and the aforementioned cleaning port 23 at the same time. Therefore, on the one hand, it is possible to avoid arranging an independent cover for the aforementioned cleaning port 23, which is beneficial to reducing the number of parts of the clothing processing device, thereby reducing the production cost and use cost of the clothing processing device, and reducing the possibility of user misoperation; on the other hand, since the dispensing unit 100 is used to hold and dispense detergent during the clothing processing process, the frequency of use is relatively high. The centralized arrangement of the dispensing device and the cleaning port 23 also helps to increase the probability of the user finding the cleaning port 23 during the process of the user dispensing detergent, thereby reminding the user to clean the drainage system or the filter system 40, which is beneficial to reducing the risk of blockage in the drainage system or the filter system 40, thereby improving the user experience of the product.

[0201] In some possible examples, the pumping unit 200 includes a peristaltic pump or a plunger pump.

[0202] In this technical solution, the pumping unit 200 may include a peristaltic pump, that is, the pumping unit 200 can use the peristaltic pump to pump the fluid in the liquid storage chamber 1101. It can be understood that the peristaltic pump has good self-priming and sealing properties, thereby improving the pumping unit 200's ability to deliver high-viscosity fluids, facilitating the pumping unit 200 to deliver cleaning agents, and reducing the risk of leakage in the pumping unit 200, thereby improving the cleanliness and reliability of the pumping unit 200.

[0203] Alternatively, the pumping unit 200 may include a plunger pump, that is, the pumping unit 200 may utilize the plunger pump to pump the fluid in the liquid storage chamber 1101. It can be understood that the plunger pump has a higher output pressure and output efficiency, thereby improving the cleaning agent delivery performance of the pumping unit 200, which is beneficial to improving the delivery efficiency of the delivery unit 100.

[0204] As shown in FIG. 12 , in some feasible examples, the bottom of the liquid storage chamber 1101 has a recessed area 1101 a , and one end of the mounting post 160 is located in the recessed area 1101 a .

[0205] It can be understood that since the magnetic levitation 310 can float on the liquid, if the amount of liquid in the liquid storage chamber 1101 is small, causing the magnetic levitation 310 to abut the bottom of the liquid storage chamber 1101, the change in the amount of the remaining liquid is difficult to be measured by the liquid amount detection unit 300, thereby reducing the detection accuracy of the liquid amount detection unit 300. Based on the consideration of the above situation, in this technical solution, the bottom of the liquid storage chamber 1101 can have a recessed area 1101a, and the mounting column 160 of the magnetic levitation 310 for positioning the liquid quantity detection unit 300 can be located in the aforementioned recessed area 1101a, thereby achieving local deepening of the liquid storage chamber 1101, increasing the buoyancy of the magnetic levitation 310 at the same depth position, and providing space for the lifting and lowering of the magnetic levitation 310. If the space above the recessed area 1101a in the liquid storage chamber 1101 is regarded as the main space of the liquid storage chamber 1101, then based on the aforementioned setting, when the liquid remaining amount in the main area is small, the magnetic levitation 310 can reflect the change in the liquid remaining amount in the main area by floating in the aforementioned recessed area 1101a, thereby further improving the user experience of the product by improving the detection range and detection accuracy of the liquid quantity detection unit 300.

[0206] In some feasible examples, when the dosing system 10 includes the pumping unit 200 , the input end of the pumping unit 200 is located in the recessed area 1101 a .

[0207] In this technical solution, the input end of the pumping unit 200 can be set to be located in the aforementioned recessed area 1101a, so that based on the aforementioned setting, the pumping device can more fully extract the liquid in the liquid storage chamber 1101, which is beneficial to reduce the liquid loss in the liquid storage chamber 1101 and improve the utilization rate of the liquid in the liquid storage chamber 1101, which is beneficial to reduce the cost of the cleaning process in actual applications.

[0208] In some feasible examples, the delivery system 10 further includes: a slide rail unit, disposed in the accommodating cavity 401; a slider unit, disposed in the box body 110, and the slider unit is slidably connected to the slide rail unit so that the box body 110 can be slidably extended or retracted into the accommodating cavity 401.

[0209] In this technical solution, the delivery system 10 may further include a slide rail unit and a slider unit, which are respectively arranged in the accommodating cavity 401 of the accommodating unit 400 and on the box body 110 of the delivery unit 100, and the slider unit is slidably connected to the slide rail unit, so that the box body 110 can be slidably extended or retracted into the accommodating cavity 401, which is beneficial to improving the movement stability and smoothness of the box body 110 and improving the operational convenience of the delivery system 10.

[0210] As shown in Figures 17 to 19, in some feasible examples, when the box body 110 includes a liquid storage box 111 and a box cover 112, the box cover 112 is detachably connected to the liquid storage box 111, the liquid storage cavity 1101 is used to accommodate fluid or a fluid container 10', and the box cover 112 is detachably provided on the liquid storage box 111; the delivery system 10 also includes: a delivery pipeline 500, the input end of the delivery pipeline 500 is located in the liquid storage cavity 1101, and when a fluid container 10' is provided in the liquid storage cavity 1101, the input end of the delivery pipeline 500 is connected to the fluid container 10'.

[0211] In this technical solution, the liquid storage box 111 and the box cover 112 of the box body 110 of the dispensing unit 100 are detachably connected. By removing the box cover 112 from the liquid storage box 111, the covered area of ​​the liquid storage cavity 1101 can be reduced, thereby improving the spatial openness and structural permeability of the liquid storage cavity 1101, thereby facilitating the insertion of fluid or a fluid container 10' into the liquid storage cavity 1101 in actual applications. The delivery system 10 may further include a delivery pipeline 500, the input end of which is located in the aforementioned liquid storage chamber 1101. Thus, when the liquid storage chamber 1101 contains fluid, the input end of the delivery pipeline 500 can be directly connected to the fluid in the liquid storage chamber 1101 and guide the fluid to flow outside the liquid storage chamber 1101. When a fluid container 10' is provided in the liquid storage chamber 1101, the input end of the delivery pipeline 500 is connected to the fluid container 10'. Thus, the input end of the delivery pipeline 500 can receive the fluid contained in the fluid container 10' and guide the fluid to flow outside the liquid storage chamber 1101. Based on the aforementioned setting, the types of objects contained in the liquid storage chamber 1101 can be expanded, thereby improving the adaptability of the delivery system 10 to different types of cleaning agents, which is beneficial to improving the user experience of the product.

[0212] It is understood that when the dispensing system 10 is applied to a cleaning device, the aforementioned fluid may be, but is not limited to, a detergent. Accordingly, the aforementioned fluid container 10' may be a detergent container suitable for machine washing, such as an ink cartridge for a cartridge-type detergent or a capsule for a capsule-type detergent. Taking the case where the dispensing system 10 is applied to a clothing processing device as an example, the output end of the aforementioned dispensing conduit 500 may be used to connect to the clothing processing chamber of the clothing processing device to guide the fluid connected to the aforementioned input end into the clothing processing chamber. When the dispensing system 10 includes the aforementioned pumping unit 200, the output end of the dispensing conduit 500 may be connected to the aforementioned pumping unit 200, so as to connect to the aforementioned clothing processing chamber through the aforementioned pumping unit 200.

[0213] It is understood that, as shown in FIG18 , when the fluid container 10′ needs to be placed in the liquid storage chamber 1101, the box cover 112 can be removed first, and then the fluid container 10′ can be placed and the delivery pipeline 500 can be docked. It should be noted that, as shown in FIG17 and FIG18 , when the fluid container 10′ is placed in the liquid storage chamber 1101, the box cover 112 can be further installed on the liquid storage box 111 to cover the liquid storage chamber 1101, or the box cover 112 can be omitted to keep the liquid storage chamber 1101 open. The size of the fluid container 10′ can be adjusted based on its actual volume. For example, if the fluid container 10′ is relatively large and easily interferes with the installation position of the box cover 112, the box cover 112 can be omitted to avoid structural damage. Conversely, if the fluid container 10′ is relatively small, the box cover 112 can be installed to ensure a stable environment inside the liquid storage chamber 1101 and a safe and reliable fluid delivery process.

[0214] As shown in FIG. 17 to FIG. 19 , in some feasible examples, the liquid amount detection unit 300 includes: a negative pressure sensor 320 for detecting the pressure in the delivery pipeline 500 .

[0215] In this technical solution, the aforementioned liquid quantity detection unit 300 may include a negative pressure sensor 320, which is used to detect the pressure in the aforementioned delivery pipeline 500, thereby determining the liquid remaining amount in the liquid storage chamber 1101 based on the detected pressure. Based on the aforementioned setting, it is beneficial to avoid the liquid quantity detection unit 300 from directly contacting the liquid in the liquid storage chamber 1101. Accordingly, it is convenient to arrange the liquid quantity detection unit 300 in the part of the delivery pipeline 500 outside the liquid storage chamber 1101, so as to improve the openness of the installation position of the liquid quantity detection unit 300 and improve the convenience of line connection. Accordingly, it can also reduce the occupation of the internal space of the liquid storage chamber 1101 by the liquid quantity detection unit 300, and can increase the effective volume of the liquid storage chamber 1101.

[0216] It is understandable that, in the case where the liquid storage cavity 1101 contains the fluid container 10 ′, the residual liquid amount in the liquid storage cavity 1101 refers to the residual liquid amount in the fluid container 10 ′.

[0217] As shown in Figures 18 and 19, in some feasible examples, the delivery pipeline 500 includes: a connector 510, which is arranged in the liquid storage cavity 1101 and is used to adapt to the container mouth of the fluid container 10'; a suction tube 520, one end of which is detachably connected to the connector 510 and the other end of which is formed with an input end.

[0218] In this technical solution, the delivery pipeline 500 may include a joint portion 510 and a suction tube 520, wherein the joint portion 510 is arranged in the aforementioned liquid storage chamber 1101 and is used to adapt to the container mouth of the aforementioned fluid container 10', and the suction tube 520 and the joint portion 510 are in a detachable connection relationship, and when the suction tube 520 is connected to the joint portion 510, the end of the suction tube 520 away from the joint portion 510 forms an input end of the delivery pipeline 500, and accordingly, when the suction tube 520 is separated from the joint portion 510, the joint portion 510 forms an input end of the delivery pipeline 500. Therefore, based on the above-mentioned arrangement, when the liquid storage chamber 1101 contains the above-mentioned fluid, the above-mentioned suction tube 520 can be set on the above-mentioned joint portion 510, so as to increase the pipeline length of the delivery pipeline 500 in the liquid storage chamber 1101, thereby expanding the distribution range of the delivery pipeline 500 in the liquid storage chamber 1101; when the liquid storage chamber 1101 contains the above-mentioned fluid container 10', the above-mentioned suction tube 520 can be removed from the above-mentioned structural portion, so that the joint portion 510 can be connected to the container mouth of the above-mentioned fluid container 10', thereby facilitating the delivery pipeline 500 to guide the fluid in the fluid container 10'.

[0219] It is understood that detergent containers suitable for machine washing, such as ink cartridges or capsules, typically have a threaded or snap-fit ​​connection structure at their openings. Accordingly, the connector 510 is adapted to fit within the container opening. This means that the connector 510 has a shape that allows it to connect and cooperate with the connection structure, allowing it to dock with the container opening. In practical applications, the connector 510 and the liquid storage box 111 can also be detachably connected. Accordingly, there can be multiple connectors 510, each with a different shape. This facilitates user selection of different connectors 510 when docking with fluid containers 10' having different connection structures.

[0220] As shown in FIG. 19 , in some feasible examples, when the suction tube 520 is connected to the joint portion 510 , the input end is arranged close to the bottom wall of the liquid storage chamber 1101 .

[0221] In this technical solution, when the suction tube 520 is connected to the joint part 510, the input end of the delivery pipeline 500 can be arranged close to the bottom wall of the liquid storage chamber 1101, that is, the end of the suction tube 520 away from the joint part 510 is arranged close to the bottom wall of the liquid storage chamber 1101. Based on the above-mentioned setting, it is convenient for the delivery pipeline 500 to guide the liquid in the bottom area of ​​the liquid storage chamber 1101, which is beneficial to improve the utilization rate of the detergent in the liquid storage chamber 1101 and reduce the loss of detergent in the liquid storage chamber 1101 during the clothing processing process, further reduce the cost of clothing processing, and improve the user experience of the product.

[0222] It can be understood that, as shown in Figure 19, the suction tube 520 can be an L-shaped tube. In actual applications, the shape of the suction tube 520 can be set according to actual needs, that is, the suction tube 520 can also be a straight tube, a curved tube, etc., and no further restrictions are made here.

[0223] In addition, since the aforementioned delivery system 10 includes the delivery unit 100 as proposed in any one of the first aspect or the second aspect, it has all the beneficial effects of the aforementioned delivery unit 100 and will not be repeated here.

[0224] As shown in Figures 1 to 19, according to the first aspect of an embodiment of the present disclosure, a dispensing system 10 is proposed, including: a dispensing unit 100, including a box body 110, a cover body 120 and a decorative plate 140, the box body 110 is formed with a liquid storage cavity 1101 and a dispensing port 1102 connected to the liquid storage cavity 1101, the cover body 120 is movably arranged on the box body 110, for covering or opening the dispensing port 1102; a accommodating unit 400, formed with an open accommodating cavity 401, the box body 110 is movably arranged on the accommodating unit 400, so that the box body 110 can extend or retract into the accommodating cavity 401; wherein the accommodating unit 400 is used to be arranged close to the cleaning port 23 of the clothing processing device, and when the box body 110 is retracted into the accommodating cavity 401, the decorative plate 140 covers the open opening and the cleaning port 23 of the accommodating cavity 401.

[0225] The dispensing system 10 provided by the embodiment of the present disclosure includes a dispensing unit 100 and a accommodating unit 400, wherein the dispensing unit 100 further includes a box body 110, a cover body 120 and a decorative plate 140, the box body 110 is formed with a liquid storage cavity 1101 and a dispensing port 1102. In actual application, the liquid storage cavity 1101 can be used to accommodate cleaning agent, and the dispensing port 1102 is connected to the liquid storage cavity 1101, so that the user can inject cleaning agent into the liquid storage cavity 1101 through the dispensing port 1102; the cover body 120 is arranged on the box body 110 and can The cover body 120 is movable relative to the box body 110, so that the cover body 120 can cover or open the liquid injection port by moving relative to the box body 110. When the cover body 120 covers the liquid injection port, the liquid storage cavity 1101 and the external space can be separated from each other, thereby preventing substances in the external environment from entering the liquid storage cavity 1101, which is beneficial to ensuring the internal cleanliness of the liquid storage cavity 1101. When the cover body 120 opens the liquid injection port, the liquid storage cavity 1101 can be connected to the external space, thereby facilitating the filling of cleaning agent or the cleaning and maintenance of the liquid storage cavity 1101.

[0226] The aforementioned accommodating unit 400 is formed with an open accommodating cavity 401, and the aforementioned box body 110 is movably connected to the accommodating unit 400 so that the box body 110 can be pulled out or pushed into the aforementioned accommodating cavity 401. Based on the aforementioned setting, during the process of the delivery system 10 delivering the cleaning agent, the liquid storage box 111 can be retracted into the aforementioned accommodating cavity 401, and then the delivery system 10 can further utilize the accommodating unit 400 to provide structural protection for the box body 110 to improve the stability and reliability of the liquid storage cavity 1101; when the cleaning agent needs to be added or the container needs to be replaced, the liquid storage box 111 can be extended out of the aforementioned accommodating cavity to facilitate user operation and improve the convenience of cleaning agent filling.

[0227] In actual applications, the dispensing system 10 provided by the embodiment of the present disclosure can be applied to clothing processing equipment, such as washing machines, washer-dryers, etc.; accordingly, the aforementioned cleaning agent can be, but is not limited to, laundry liquid, softener, detergent, disinfectant, etc. Taking the application of the aforementioned dispensing unit 100 to a washing machine as an example, the aforementioned box body 110 can be set on the casing of the washing machine, the aforementioned liquid storage chamber 1101 can be used to store cleaning agents such as laundry liquid and softener, and the aforementioned liquid storage chamber 1101 of the aforementioned dispensing unit 100 can be used to connect to the clothing processing chamber of the washing machine, so that during the process of washing clothes, the cleaning agent in the dispensing unit 100 can be dispensed into the clothing processing chamber to participate in the clothing washing operation, avoiding the user from directly pouring the cleaning agent into the clothing processing chamber, which is conducive to improving the convenience of cleaning agent dispensing and the accuracy of usage.

[0228] It is understandable that the space of the clothing processing chamber is relatively large. If the user directly adds detergent into the clothing processing chamber, it is often inconvenient to control the amount of detergent added; when the clothing processing equipment is equipped with a dosing system 10, the volume of the liquid storage chamber 1101 is relatively limited, which makes it convenient for the user to directly observe the amount of detergent added during the filling process, thereby helping to improve the accuracy of detergent usage.

[0229] In practical applications, the accommodating unit 400 can be provided in the casing of the clothing processing device to ensure the stability of the accommodating unit 400 and the dispensing unit 100. At the same time, when the casing of the clothing processing device is provided with a cleaning port 23, the accommodating unit 400 can be used to be arranged close to the cleaning port 23 of the clothing processing device. When the box body 110 is retracted into the accommodating cavity 401, a decorative plate portion 140 can be provided to simultaneously cover the opening of the accommodating cavity 401 and the cleaning port 23. Based on the above arrangement, on the one hand, it is possible to avoid arranging an independent cover for the cleaning port 23, which is conducive to reducing the number of parts of the clothing processing device, and further reducing the production cost and On the other hand, since the dispensing unit 100 is used to contain and dispense detergent during the clothing processing process, and thus has a relatively high frequency of use, centrally arranging the dispensing device and the cleaning port 23 can also help increase the probability of users finding the cleaning port 23 during the process of users dispensing detergent, thereby playing a role in reminding users to clean the drainage system or the filter system 40, which is beneficial to reduce the risk of blockage in the drainage system or the filter system 40, and thus improve the user experience of the product.

[0230] It is understandable that the clothing processing equipment usually has a drainage system or a filter system 40. Accordingly, a cleaning port 23 corresponding to the cleaning end 41 of the aforementioned drainage system or filter system 40 is opened on the housing assembly 20 of the clothing processing equipment to facilitate the user to regularly clean the drainage system or filter system 40 and reduce the chance of blockage of components or pipes.

[0231] It should be noted that a small-sized clothing processing device generally refers to a clothing processing device with a clothing processing capacity of less than 3 kg. Accordingly, the volume of a small-sized clothing processing device is often small and the space is relatively compact. The dispensing system 10 provided by the present disclosure is based on the above-mentioned configuration. On the one hand, the dispensing unit 100 can be made to have a retractable state, so that when there is a need to add detergent, the dispensing unit 100 can be extended from the accommodating chamber 401 to facilitate the user to add detergent into the liquid storage chamber 1101. After the detergent is added, the dispensing unit 100 can be retracted, thereby reducing the space occupied by the dispensing system 10 and facilitating the application of the dispensing unit 100 to a small clothing processing device. On the other hand, the area near the dispensing port 1102 of the clothing processing device is usually only equipped with a drainage pipe or a filter device, so that the space is relatively abundant. By arranging the accommodating unit 400 close to the cleaning port 23, the space utilization rate of the small clothing processing device can be improved, and a significant increase in the volume of the small clothing processing device due to the addition of the dispensing system 10 can be prevented. On the other hand, by arranging the decorative plate portion 140 of the dispensing unit 100 to cover the cleaning port 23 at the same time, it is further possible to avoid configuring an independent cover for the cleaning port 23, thereby reducing the number of components of the small clothing processing device, which is conducive to ensuring the lightweight level of the small clothing processing system. Therefore, the dispensing system 10 provided by the present disclosure has good applicability for small-sized clothing processing equipment, and is conducive to expanding the functions of small-sized clothing processing equipment in practical applications, thereby providing favorable conditions for expanding the application scope of small-sized clothing processing equipment.

[0232] It can be understood that the accommodating unit 400 can be fixedly set on the casing of the clothing processing device, for example, set on the inner side of the casing of the clothing processing device, and the opening of the accommodating cavity 401 is arranged toward the outside of the casing, so that the box body 110 of the dispensing unit 100 can be extended and retracted relative to the casing of the clothing processing device while being extended and retracted relative to the accommodating cavity 401.

[0233] As shown in FIG. 10 , in some examples, the delivery system 10 further includes: a pumping unit 200 , which is connected to the liquid storage chamber 1101 and is used to discharge the fluid in the liquid storage chamber 1101 .

[0234] In this technical solution, the delivery system 10 may further include a pumping unit 200 connected to the output end of the aforementioned delivery pipeline 500. In actual application, the pumping unit 200 is used to pump fluid from the input end to the output end of the delivery pipeline 500. When the delivery system 10 is applied to a clothing processing device, the pumping unit 200 is used to pump the fluid into the clothing processing chamber. Based on the aforementioned setting, the fluid delivery efficiency of the delivery system 10 can be improved, and the requirements of the delivery system 10 for the setting location can be reduced, thereby improving the space utilization of the clothing processing device and improving the miniaturization and lightweight level of the clothing processing device.

[0235] In some examples, pumping unit 200 includes a peristaltic pump or a plunger pump.

[0236] In this technical solution, the pumping unit 200 may include a peristaltic pump, that is, the pumping unit 200 may use the peristaltic pump to pump the fluid in the liquid storage chamber 1101. It can be understood that the peristaltic pump has good self-priming and sealing properties, thereby improving the pumping unit 200's ability to deliver high-viscosity fluids, facilitating the pumping unit 200 to deliver detergents, and reducing the risk of leakage in the pumping unit 200, thereby improving the cleanliness and reliability of the pumping unit 200.

[0237] Alternatively, the pumping unit 200 may include a plunger pump, that is, the pumping unit 200 may utilize the plunger pump to pump the fluid in the liquid storage chamber 1101. It can be understood that the plunger pump has a higher output pressure and output efficiency, thereby improving the detergent delivery performance of the pumping unit 200, which is beneficial to improving the delivery efficiency of the delivery unit 100.

[0238] As shown in FIG. 12 , in some examples, the dispensing unit 100 further includes a liquid amount detection unit 300 for detecting the remaining amount of liquid in the liquid storage chamber 1101 .

[0239] In this technical solution, the aforementioned dispensing system 10 may also include a liquid quantity detection unit 300, which is used to detect the remaining liquid in the liquid storage chamber 1101, thereby facilitating the user to understand the usage status of the detergent during use, which is conducive to further improving the ease of use of the dispensing system 10.

[0240] As shown in Figure 12, in some examples, the liquid quantity detection unit 300 includes: a magnetic levitation 310, and the dispensing unit 100 also includes a mounting column 160, the mounting column 160 is located in the liquid storage chamber 1101 and is arranged along the depth direction of the liquid storage chamber 1101, and the magnetic levitation 310 is movably mounted on the mounting column 160.

[0241] In this technical solution, the aforementioned liquid quantity detection unit 300 may include a magnetic levitation 310, and the dispensing unit 100 also includes a mounting column 160. The mounting column 160 is located in the liquid storage chamber 1101 and is arranged along the depth direction of the liquid storage chamber 1101. The magnetic levitation 310 is movably mounted on the mounting column 160. Based on the aforementioned setting, the range of movement of the aforementioned magnetic levitation 310 can be constrained to ensure the smooth operation of the magnetic levitation 310.

[0242] It can be understood that when the liquid quantity detection unit 300 includes the aforementioned magnetic levitation 310, the liquid quantity detection unit 300 is also a magnetic levitation 310 type liquid level sensor. Accordingly, when there is liquid in the liquid storage chamber 1101, the magnetic levitation 310 will float on the liquid and rise and fall with the change of liquid level. Accordingly, the magnetic levitation 310 type liquid level sensor can also include components such as magnetic switches for sensing the position of the magnetic levitation 310, and processing components that convert the aforementioned position into liquid quantity information, thereby obtaining the remaining liquid in the liquid storage chamber 1101.

[0243] As shown in FIG. 12 , in some examples, the bottom of the liquid storage chamber 1101 has a recessed area 1101 a , and one end of the mounting post 160 is located in the recessed area 1101 a .

[0244] It can be understood that since the magnetic levitation 310 can float on the liquid, if the amount of liquid in the liquid storage chamber 1101 is small, causing the magnetic levitation 310 to abut the bottom of the liquid storage chamber 1101, the change in the amount of the remaining liquid is difficult to be measured by the liquid amount detection unit 300, thereby reducing the detection accuracy of the liquid amount detection unit 300. Based on the consideration of the above situation, in this technical solution, the bottom of the liquid storage chamber 1101 can have a recessed area 1101a, and the mounting column 160 of the magnetic levitation 310 for positioning the liquid quantity detection unit 300 can be located in the aforementioned recessed area 1101a, thereby achieving local deepening of the liquid storage chamber 1101, increasing the buoyancy of the magnetic levitation 310 at the same depth position, and providing space for the lifting and lowering of the magnetic levitation 310. If the space above the recessed area 1101a in the liquid storage chamber 1101 is regarded as the main space of the liquid storage chamber 1101, then based on the aforementioned setting, when the liquid remaining amount in the main area is small, the magnetic levitation 310 can reflect the change in the liquid remaining amount in the main area by floating in the aforementioned recessed area 1101a, thereby further improving the user experience of the product by improving the detection range and detection accuracy of the liquid quantity detection unit 300.

[0245] In some examples, when the dosing system 10 includes a pumping unit 200 , the input end of the pumping unit 200 is located within the recessed area 1101 a .

[0246] In this technical solution, the input end of the pumping unit 200 can be set to be located in the aforementioned recessed area 1101a, so that based on the aforementioned setting, the pumping device can more fully extract the liquid in the liquid storage chamber 1101, which is beneficial to reduce the liquid loss in the liquid storage chamber 1101 and improve the utilization rate of the liquid in the liquid storage chamber 1101, which is beneficial to reduce the cost of the cleaning process in actual applications.

[0247] As shown in Figures 12 and 13, in some examples, the accommodating unit 400 is also formed with a first limiting structure 402, and the dispensing unit 100 also includes a second limiting structure 150, which is detachably connected to the first limiting structure 402. When the box body 110 is retracted into the accommodating cavity 401, the second limiting structure 150 is connected to the first limiting structure 402.

[0248] In this technical solution, the aforementioned accommodating unit 400 can be formed with a first limiting structure 402, and the aforementioned delivery unit 100 can also include a second limiting structure 150. When the box body 110 is pushed into the accommodating cavity 401, the second limiting structure 150 is connected to the first limiting structure 402, so that the delivery system 10 can fix the relative position between the accommodating unit 400 and the delivery unit 100 based on the matching relationship between the aforementioned first limiting structure 402 and the aforementioned second limiting structure 150, thereby reducing the possibility of the delivery unit 100 accidentally falling out of the accommodating unit 400 during use.

[0249] As shown in Figures 12 and 13, in some feasible examples, the aforementioned first limiting structure 402 can be a fixed column, and the aforementioned second limiting structure 150 can be a buckle, and the aforementioned buckle can be detachably connected to the aforementioned fixed column, so that the first limiting structure 402 and the second limiting structure 150 can be fixed by snapping.

[0250] It should be noted that, in actual applications, the aforementioned accommodating unit 400 may be disposed in the housing of the cleaning device, or may also be integrally formed in the housing of the aforementioned cleaning device.

[0251] In some examples, the delivery system 10 further includes: a slide rail unit, which is disposed in the accommodating cavity 401; and a slider unit, which is disposed in the box body 110, and the slider unit is slidably connected to the slide rail unit, so that the box body 110 can be slidably extended or retracted into the accommodating cavity 401. In this technical solution, the delivery system 10 can also include a slide rail unit and a slider unit, which are respectively disposed in the accommodating cavity 401 of the accommodating unit 400 and on the box body 110 of the delivery unit 100, and the slider unit is slidably connected to the slide rail unit, so that the box body 110 can be slidably extended or retracted into the accommodating cavity 401, which is conducive to improving the movement stability and smoothness of the box body 110 and improving the operational convenience of the delivery system 10.

[0252] As shown in FIG. 2 , in some feasible examples, the cover 120 has at least two operating ends 1201 ; when the cover 120 covers the loading port 1102 , an operating space 1202 is formed between each operating end 1201 and the box body 110 .

[0253] In this technical solution, the aforementioned cover body 120 has an operating end 1201. In actual application, the aforementioned operating end 1201 can be used to withstand the driving force, which is the external force used to drive the cover body 120 to move relative to the box body 110 to realize the opening or closing of the liquid injection port. For example, when the user manually operates the cover body 120, the aforementioned operating end 1201 can be used to contact the operator's hand and withstand the driving force applied by the operator's hand; accordingly, when the aforementioned cover body 120 covers the aforementioned injection port 1102, an operating space 1202 is formed between the aforementioned operating end 1201 and the aforementioned box body 110. The aforementioned operating space 1202 can provide a passable space for the user's hand to approach and contact the aforementioned operating end 1201, thereby facilitating the user to operate the cover body 120.

[0254] The number of the aforementioned operating ends 1201 is at least two, and when the cover body 120 covers the injection port 1102, an operating space 1202 is formed between each operating end 1201 and the box body 110, so that the user's hand can contact multiple parts of the cover body 120 at the same time (for example: opposite sides, which is convenient for the user to hold), and the aforementioned driving force can be applied to multiple parts of the cover body 120 at the same time, so that during the operation of switching the injection port from a covered state to an open state, on the one hand, it can be beneficial to increase the contact area between the cover body 120 and the user's hand, expand the feasible contact orientation between the cover body 120 and the user's hand, thereby improving the user's force application convenience during operation, reducing the difficulty of opening the injection port 1102, and improving the product's user experience; on the other hand, it is also beneficial to prevent the cover body 120 from being subjected to a more concentrated driving force, improve the force dispersion and balance of the cover body 120, thereby reducing the probability of damage to the cover body 120 in actual application, and reducing the maintenance and use costs of the injection unit 100.

[0255] It is understood that the at least two operating ends 1201 can be at least two different ends of the cover 120. For example, when the cover 120 is a plate-like structure, the operating end 1201 can be a plate end in the length direction or width direction of the plate-like structure. The at least two operating ends 1201 can be adjacent to each other or spaced apart from each other. For example, as shown in Figure 4, the cover 120 can be a generally rectangular (in some embodiments, the cover 120 is a square) plate-like structure as a whole, so that there are four ends in the length direction and width direction of the cover 120. For the cover 120 with a rectangular plate-like structure, the number of the operating ends 1201 can be greater than or equal to two and less than or equal to four. Considering the connection between the cover 120 and the box body 110, the number of the operating ends 1201 of the cover 120 with a rectangular plate-like structure can be less than or equal to three. That is, in actual application, one end in the length or width direction of the cover 120 can be used to connect the box body 110. It can be understood that the shape of the cover body 120 can be but is not limited to a rectangular plate structure, and can also be other polygonal plate structures, such as a triangular plate structure, a pentagonal plate structure, a hexagonal plate structure, etc. Accordingly, the number of operating ends 1201 can also be set in combination with the shape of the cover body 120 and actual needs.

[0256] It should be noted that some conventional dispensing units 100 typically include a box body and a lid body. The box body defines an open liquid storage space, and the lid body is used to cover or open the opening of the liquid storage space. Furthermore, the box body often has a small notch structure on one side of the lid body. When the lid body covers the opening, if a user needs to open the opening, they can only insert a single fingernail through the small notch structure on the side of the lid body. As a result, the user can often only apply force to the lid body from a single position. This is not only difficult to operate and has a poor user experience, but also, due to the cramped space, it is not easy for the user to control the direction and magnitude of the force applied, which can easily cause damage to the lid body. The dispensing unit 100 provided in the present embodiment, based on the above-mentioned configuration, can increase the contact area between the lid body 120 and the user's hand, expand the possible contact directions between the lid body 120 and the user's hand, improve the user's convenience in applying force during operation, and facilitate improving the force distribution and balance of the lid body 120, thereby reducing the chance of damage to the lid body 120 during actual use.

[0257] As shown in FIG. 6 , in some feasible examples, the cover portion 120 and the box body 110 have the same width, and the cover portion 120 has an operating end 1201 .

[0258] The aforementioned cover body 120 has an operating end 1201. In actual application, the aforementioned operating end 1201 can be used to withstand the driving force, which is the external force used to drive the cover body 120 to move relative to the box body 110 to realize the opening or closing of the liquid injection port. For example, when the user manually operates the cover body 120, the aforementioned operating end 1201 can be used to contact the operator's hand and withstand the driving force applied by the operator's hand; accordingly, when the aforementioned cover body 120 covers the aforementioned injection port 1102, an operating space 1202 is formed between the aforementioned operating end 1201 and the aforementioned box body 110. The aforementioned operating space 1202 can provide a passable space for the user's hand to approach and contact the aforementioned operating end 1201, thereby facilitating the user to operate the cover body 120.

[0259] At the same time, the width of the cover 120 is consistent with the width of the box body 110, which allows the cover 120 to have a relatively high width, thereby facilitating the user's hand to operate with a wider opening, thereby reducing the possibility of interference between the user's fingers during operation, and further improving the ease of operation of the cover 120. Accordingly, when the cover 120 is relatively large, the user can grasp the cover 120 to operate it, that is, the user can apply force to each operating end 1201 with two fingers, further improving the ease of operation of the cover 120.

[0260] It can be understood that the width of the aforementioned cover portion 120 is consistent with the width of the box body portion 110, that is, the cover portion 120 has a width similar to that of the box body portion 110 (for example, the same or slightly smaller width), and has an overall shape that is adapted to the box body portion 110 (for example: an overall shape consistent with the box body portion 110), thereby ensuring that the cover portion 120 has a higher width for user operation while making the dispensing unit 100 have a higher aesthetics.

[0261] For example, the width of the cover 120 can be greater than or equal to 0.8 times the width of the box body 110 and less than or equal to the width of the box body 110. This, on the one hand, allows the width of the box body 110 to be highly consistent with the width of the cover 120, thereby facilitating the user's hand-stretching operation and further improving the ease of operation of the cover 120. On the other hand, it also prevents the width of the cover 120 from being too large, thereby ensuring the compactness of the dispensing unit 100 and improving the aesthetics of the dispensing unit 100. For example, the width of the cover 120 can be, but is not limited to, 0.8 times, 0.85 times, 0.9 times, 0.9 times, 1 times, etc., of the width of the box body 110. The width ratio between the cover 120 and the box body 110 can be set according to actual needs and is not further limited here.

[0262] It can be understood that, when the cover portion 120 is a plate-like structure, the operating end 1201 can be a plate end in the width direction of the plate-like structure.

[0263] It should be noted that some conventional dispensing units 100 typically include a box body and multiple covers. The box body has multiple open liquid storage spaces, and the covers are used to cover or open the openings of the aforementioned liquid storage spaces one by one. As a result, the size of the covers is often smaller than the box body, and the box body typically has a small notch structure on one side corresponding to the cover. When the cover covers the aforementioned opening, if the user needs to open the aforementioned opening, they can only insert a single fingernail through the aforementioned small notch structure on the side of the cover. This is not only difficult to operate and has a poor user experience, but also, due to the cramped space, it is not easy for the user to control the direction and magnitude of the force applied, which can easily cause damage to the cover. Based on the above-mentioned configuration, the dispensing unit 100 provided in the embodiment of the present disclosure can increase the width of the cover portion 120, thereby facilitating the contact area between the cover portion 120 and the user's hand, making it easier for the user to apply force during operation, thereby reducing the chance of damage to the cover portion 120 in actual use.

[0264] In some feasible examples, the aforementioned operating end 1201 may be provided with anti-slip grooves to further facilitate the user to apply force to the cover body 120.

[0265] In some feasible examples, the length of the aforementioned operating space 1202 is greater than or equal to the length of the aforementioned operating end 1201, so that the operating space 1202 can correspond to the entire side of the cover body 120, expand the distribution range of the operating space 1202, and further improve the operating convenience of the cover body 120. It can be understood that the length of the aforementioned operating end 1201 is also the dimension of the operating end 1201 in the extension direction. Taking the case where the cover body 120 is a rectangular plate structure as an example, if the aforementioned operating end 1201 is one end in the length direction of the rectangular plate structure, then the operating end 1201 corresponds to the long side of the rectangular plate structure. Accordingly, the operating end 1201 extends along the length direction of the rectangular plate structure. Similarly, if the operating end 1201 is one end in the length direction of the rectangular plate structure, then the operating end 1201 extends along the width direction of the rectangular plate structure. Accordingly, the length direction of the aforementioned operating space 1202 is consistent with the length direction of the aforementioned operating end 1201.

[0266] As shown in FIG. 2 , FIG. 1 , FIG. 4 and FIG. 5 , in some examples, there are two operating ends 1201 , and the two operating ends 1201 face away from each other.

[0267] In this technical solution, the number of the aforementioned operating ends 1201 can be two, and the two aforementioned operating ends 1201 are separated from each other, that is, the two ends of the cover body 120 that are separated from each other can serve as the aforementioned two operating ends 1201. Based on the aforementioned setting, the spacing distance between the aforementioned two operating ends 1201 can be expanded, and then while being able to facilitate the user to apply force to different parts of the cover body 120 at the same time, the force balance of the cover body 120 during use is further improved, which is beneficial to further reduce the chance of damage to the cover body 120 and improve the convenience of opening the injection port 1102.

[0268] It is understandable that, when the two operating ends 1201 face away from each other, when the cover 120 covers the aforementioned delivery port 1102 , two operating spaces 1202 will be correspondingly formed between the cover 120 and the box body 110 .

[0269] It is understood that in actual use, the size of the cover 120 can be set according to actual needs. When the cover 120 is relatively small, the user can operate the cover 120 with a single finger. Based on the above configuration, the distance between the two operating spaces 1202 can be relatively large, thereby facilitating the user's hand to operate with a larger opening, thereby reducing the possibility of interference between the user's fingers during operation, and further improving the ease of operation of the cover 120. Accordingly, when the cover 120 is relatively large, the user can grasp the cover 120 to operate it, that is, the user can apply force to each operating end 1201 with two fingers, which further improves the ease of operation of the cover 120.

[0270] In some feasible examples, the cover portion 120 has a width similar to that of the box body portion 110 (for example, the same or slightly smaller width), and has an overall shape that is compatible with the box body portion 110 (for example: an overall shape consistent with the box body portion 110), thereby ensuring that the cover portion 120 has a higher width for user operation while making the dispensing unit 100 have a higher aesthetics.

[0271] In some feasible examples, the distance between the two operating ends 1201 that are separated from each other is adapted to the width of the box body 110. For example, the distance between the two operating ends 1201 that are separated from each other can be greater than or equal to 0.5 times the width of the box body 110, and less than or equal to 0.95 times the width of the box body 110. On the one hand, this can make the distance between the two operating ends 1201 that are separated from each other larger, increase the span between the operating ends 1201 and the overall width of the cover body 120, thereby facilitating the user's hand-stretching operation and further improving the operational convenience of the cover body 120. On the other hand, it can also avoid the width of the cover body 120 being too large, which is conducive to ensuring the structural compactness of the delivery unit 100 and improving the aesthetics of the delivery unit 100. For example, the distance between the two operating ends 1201 facing away from each other can be but not limited to 0.55 times, 0.6 times, 0.7 times, 0.8 times, 0.9 times, etc., of the width of the box body 110. The aforementioned distance can be set according to actual needs and is not limited here.

[0272] As shown in Figure 3, in some examples, the box body 110 is formed with a groove 1103, and the delivery port 1102 is arranged in the groove 1103. When the cover body 120 covers the delivery port 1102, the cover body 120 is located in the groove 1103, and an operating space 1202 is defined in the groove 1103.

[0273] In this technical solution, the box body 110 may be formed with a groove 1103, and the delivery port 1102 may be formed in the groove 1103, that is, the groove 1103 and the liquid storage chamber 1101 may be arranged adjacent to each other and communicate with each other. When the cover 120 covers the delivery port 1102, the cover 120 is located in the groove 1103 and defines the operating space 1202 in the groove 1103, thereby avoiding the cover 120 from protruding from the box body 110, improving the structural concealment of the cover 120 when covering the delivery port 1102, and thus improving the aesthetics of the delivery unit 100 and further enhancing the user experience of the product. On the other hand, it can also reduce the possibility of external structures contacting the cover 120, reduce the probability of the delivery port 1102 being accidentally opened, and help to further avoid damage to the cover 120, providing further protection for reducing the use cost of the delivery unit 100.

[0274] As shown in Figure 3, in some feasible examples, the part of the aforementioned box body 110 corresponding to the aforementioned operating end 1201 can be formed with an opening, and the aforementioned opening is connected to the aforementioned groove 1103. Accordingly, when the aforementioned cover body 120 covers the aforementioned delivery port 1102, the aforementioned opening is connected to the aforementioned operating space 1202, which is conducive to improving the passability of the operating space 1202, and further facilitates the user's hand to contact the operating end 1201 of the cover body 120 through the operating space 1202, thereby further improving the convenience of the opening operation of the delivery port 1102.

[0275] As shown in Figure 3, in some examples, the loading port 1102 is formed on the bottom wall of the groove 1103. When the cover 120 covers the loading port 1102, the side of the cover 120 away from the loading port 1102 is flush with the side of the box body 110.

[0276] In this technical solution, the aforementioned delivery port 1102 can be formed on the bottom wall of the aforementioned groove 1103. It can be understood that the aforementioned groove 1103 is an open groove, and the bottom wall of the aforementioned groove 1103 is also the groove wall opposite to the aforementioned groove. When the aforementioned cover body 120 covers the aforementioned delivery port 1102, one side of the cover body 120 can abut against the bottom wall of the aforementioned groove 1103 to achieve coverage of the aforementioned delivery port 1102. Accordingly, the side of the cover body 120 away from the delivery port 1102 can be arranged to be aligned with the box body 1103. For example, it is flush with the side of the box body 110 on which the aforementioned groove 1103 is formed. Then, when the aforementioned cover body 120 covers the aforementioned delivery port 1102, the side of the delivery unit 100 on which the aforementioned cover body 120 is provided can have a higher surface flatness. On the one hand, it is beneficial to improve the shape matching between the cover body 120 and the groove 1103, and further improve the aesthetics of the delivery unit 100. On the other hand, it is also beneficial to further enhance the structural compactness of the delivery unit 100 and enhance the miniaturization level of the delivery unit 100.

[0277] It can be understood that by opening the aforementioned delivery port 1102 on the bottom wall of the aforementioned groove 1103, the aforementioned delivery port 1102 can also be directed towards the notch of the aforementioned groove 1103, so that when the cover body 120 opens the aforementioned delivery port 1102, it can be further convenient for the operator to inject the cleaning agent into the aforementioned delivery port 1102, which is conducive to further improving the ease of use of the delivery unit 100.

[0278] As shown in Figure 8, in some examples, the cover body 120 includes a main plate segment 121, a first curved plate segment 122 and a second curved plate segment 123, and the main plate segment 121 is connected between the first curved plate segment 122 and the second curved plate segment 123; the groove 1103 includes a main groove segment 1103a, a first side groove segment 1103b and a second side groove segment 1103c, and the main groove segment 1103a is located between the first side groove segment 1103b and the second side groove segment 1103c; wherein, the shape of the main plate segment 121 is adapted to the shape of the main groove segment 1103a, and the first curved plate segment 122 and the second curved plate segment 123 are respectively consistent with the curvature of the corresponding positions of the box body 110.

[0279] In this technical solution, the aforementioned cover body 120 may include a first arc-shaped plate segment 122, a main body plate segment 121 and a second arc-shaped plate segment 123 connected in sequence. Correspondingly, the aforementioned groove 1103 may include a first side groove segment 1103b, a main body groove segment 1103a and a second side groove segment 1103c connected in sequence. The aforementioned first arc-shaped plate segment 122, the main body plate segment 121 and the second arc-shaped plate segment 123 correspond to the aforementioned first side groove segment 1103b, the main body groove segment 1103a and the second side groove segment 1103c, respectively. That is, when the aforementioned cover body 120 covers the aforementioned loading port 1102, the first arc-shaped plate segment 122 is located in the aforementioned first side groove segment 1103b, and the main body plate segment 121 is located in the aforementioned 21 is located in the main groove section 1103a, and the second arc-shaped plate section 123 is located in the second side groove section 1103c. It can be understood that the aforementioned delivery port 1102 can be opened on the bottom wall of the aforementioned main groove section 1103a. Accordingly, the cover body 120 can use the main plate section 121 to cover or open the aforementioned delivery port 1102, and based on the aforementioned setting, both ends of the main plate section 121 are arc-shaped plate sections, so that the contour of the outer edge of the cover body 120 can be smoother, which is conducive to reducing the angular structure of the edge of the cover body 120, reducing the risk of scratches when the user operates, further improving the convenience of opening and closing the delivery port 1102, and helping to further improve the aesthetics of the delivery unit 100.

[0280] Among them, the shape of the main plate section 121 can be adapted to the shape of the main groove section 1103a, so that when the cover body 120 covers the delivery port 1102, the main plate section 121 and the main groove section 1103a can be more fitted together, making it convenient to make the main plate section 121 and the corresponding partial groove openings of the main groove section 1103a flush, and reduce the fitting gap between the main plate section 121 and the main groove section 1103a, which is beneficial to improve the aesthetics of the delivery unit 100 while reducing the risk of liquid overflow.

[0281] At the same time, the first curved plate segment 122 and the second curved plate segment 123 can be set to be consistent with the curvature of the corresponding position of the box body 110. It should be noted that the position corresponding to the aforementioned box body 110 and the aforementioned first curved plate segment 122 includes the first side groove segment 1103b, so that the aforementioned first side groove segment 1103b can be a curved groove segment; the position corresponding to the aforementioned box body 110 and the aforementioned first curved plate segment 122 includes the second side groove segment 1103c, so that the aforementioned second side groove segment 1103c can also be a curved groove segment; and based on the aforementioned setting, each curved plate segment and the corresponding side groove segment can have a curvature with a high degree of matching, which is conducive to making each curved plate segment more fit against the groove wall of the corresponding side groove segment when the cover body 120 covers the delivery port 1102, thereby reducing the matching gap between the curved plate segment and the corresponding side groove segment, which is conducive to further improving the aesthetics of the delivery unit 100 while reducing the risk of liquid overflow.

[0282] For example, as shown in Figures 2, 3 and 7, the aforementioned delivery port 1102 is formed on the bottom wall of the main groove section 1103a. The bottom wall of the aforementioned main groove section 1103a can be a plane. Accordingly, the main plate section 121 can be a plate-shaped structure with high flatness, so that the main groove section 1103a and the main plate section 121 can be matched; the bottom walls of the first side groove section 1103b and the second side groove section 1103c are inclined from the inside to the outside, and can also be arc-shaped walls, and smoothly transition with the bottom wall of the main groove section 1103a, thereby increasing the operating space 1202 of the user's fingers and improving the smoothness of the groove wall of the groove 1103, which is conducive to reducing the angular structure of the groove wall of the groove 1103. Improve the cleaning convenience and aesthetics of the groove 1103; the aforementioned curved wall surface can be a convex curved surface, that is, the aforementioned curved wall surface is a curved surface that is convex toward the space in the groove, and the aforementioned first curved plate segment 122 is used to match the plate surface of the bottom wall of the first side groove segment 1103b can be a concave curved surface, and the aforementioned second curved plate segment 123 is used to match the plate surface of the bottom wall of the second side groove segment 1103c can also be a concave curved surface, so that each curved plate segment can adapt to the corresponding side groove segment, and can accordingly make the first curved plate segment 122 and the second curved plate segment 123 facing away from the side of the delivery port 1102 to be convex curved surface, which is beneficial to improve the aesthetics of the cover body 120 while ensuring the ease of operation of the cover body 120.

[0283] As shown in FIG. 2 , in some feasible examples, the cover portion 120 and the box body portion 110 have a consistent overall appearance. For example, the side of the box body 110 on which the groove 1103 is formed may also have a main decorative surface 1104, a first side decorative surface 1105 and a second side decorative surface 1106, and the main decorative surface 1104, the first side decorative surface 1105 and the second side decorative surface 1106 are all located on the groove periphery of the groove 1103, and the main decorative surface 1104 corresponds to the main groove section 1103a, the first side decorative surface 1105 corresponds to the first side groove section 1103b, and the second side decorative surface 1106 corresponds to the second side groove section 1103c; accordingly, the position of the box body 110 corresponding to the first curved plate section 122 also includes the first side decorative surface 1105, and the position of the box body 110 corresponding to the second curved plate section 123 also includes the second side decorative surface 1106, that is, the first side decorative surface 1105 corresponds to the second side decorative surface 1106 can both be curved surfaces, and the curvature of the aforementioned first side finishing surface 1105 and the curvature of the aforementioned second side finishing surface 1106 are respectively consistent with the curvature of the aforementioned first curved plate segment 122 and the curvature of the aforementioned second curved plate segment 123; when the cover body 120 covers the aforementioned delivery port 1102, the side of the first curved plate segment 122 facing away from the delivery port 1102 is flush with the first side finishing surface 1105, the side of the second curved plate segment 123 facing away from the delivery port 1102 is flush with the second side finishing surface 1106, and the side of the main plate segment 121 facing away from the delivery port 1102 is flush with the main finishing surface 1104. Based on the above-mentioned setting, when the cover body 120 covers the aforementioned delivery port 1102, the side of the delivery unit 100 provided with the aforementioned cover body 120 can have a higher surface flatness, which is conducive to further improving the aesthetics of the delivery unit 100.

[0284] As shown in Figure 8, in some feasible examples, the edge of the groove 1103 can have multiple rounded transition structures, and accordingly, the edge of the cover body 120 can also have multiple rounded transition structures, which is conducive to further reducing the sharp corners of the groove 1103 and the cover plate, thereby helping to improve the aesthetics of the delivery unit 100 while ensuring the safety of operation.

[0285] In some feasible examples, the first arc-shaped plate segment 122 , the main body plate segment 121 and the second arc-shaped plate segment 123 are an integrated structure.

[0286] As shown in Figure 7, in some feasible examples, the aforementioned cover body 120 may also include a delivery plug 124, which is arranged on one side of the aforementioned main plate section 121 and includes a raised plug frame and a sealing ring, which is used to removably close the aforementioned delivery port 1102. When the cover body 120 covers the delivery port 1102, the delivery plug 124 is inserted into the aforementioned delivery port 1102, thereby being able to seal the delivery port 1102.

[0287] As shown in Figure 2, in some examples, the width B1 of the first arcuate plate segment 122 is smaller than the width C1 of the first side groove segment 1103b. When the cover body 120 covers the loading port 1102, an operating space 1202 is defined between the first arcuate plate segment 122 and the first side groove segment 1103b; the width of the second arcuate plate segment 123 is smaller than the width of the second side groove segment 1103c. When the cover body 120 covers the loading port 1102, an operating space 1202 is defined between the second arcuate plate segment 123 and the second side groove segment 1103c.

[0288] In this technical solution, the width B1 of the first arc-shaped plate segment 122 can be set to be smaller than the width C1 of the first side groove segment 1103b, and the width of the second arc-shaped plate segment 123 can be set to be smaller than the width of the second side groove segment 1103c, so that when the cover body 120 covers the aforementioned delivery port 1102, the first arc-shaped plate segment 122 defines an operating space 1202 in the first side groove segment 1103b, and the second arc-shaped plate segment 123 defines an operating space 1202 in the second side groove segment 1103c, so that when the cover body 120 covers the delivery port 1102, the delivery unit 100 can have two operating spaces 1202, and the two operating spaces 1202 are respectively located in the cover body 120. 0 are at two ends that are away from each other, and thus, on the one hand, the spacing distance between the two operating ends 1201 can be expanded, and thus, while being convenient for the user to apply force to different parts of the cover body 120 at the same time, the force balance of the cover body 120 during use is further improved, which is beneficial to further reduce the probability of damage to the cover body 120 and improve the convenience of opening the delivery port 1102; on the other hand, it is also convenient for the user to operate the cover body 120 through the first arc-shaped plate segment 122 and the second arc-shaped plate segment 123 when performing the opening or covering operation of the delivery port 1102, and because the contours of the first arc-shaped plate segment 122 and the second arc-shaped plate segment 123 are relatively smooth and the number of angular structures is relatively small, it is more convenient for the user to operate.

[0289] As shown in FIG5 , in some examples, the thickness of the first curved plate segment 122 decreases along the direction from the main plate segment 121 to the first curved plate segment 122, and the thickness of the second curved plate segment 123 decreases along the direction from the main plate segment 121 to the second curved plate segment 123. In this technical solution, the thickness of the first curved plate segment 122 can be set to decrease along the direction from the main plate segment 121 to the first curved plate segment 122, and correspondingly, the thickness of the second curved plate segment 123 can be set to decrease along the direction from the main plate segment 121 to the second curved plate segment 123. Based on this arrangement, the portions of the first and second curved plate segments 122 and 123 away from the main plate segment 121 can be thinner, which further improves the convenience of the user when manually opening and closing the delivery port 1102, and helps reduce the weight and volume of the cover 120, thereby reducing the overall manufacturing cost of the cover 120 and the delivery unit 100, and further reducing the cost of use of the delivery unit 100.

[0290] As shown in FIG. 2 and FIG. 1 , in some examples, the dispensing unit 100 further includes: a hinge portion 130 disposed between the cover portion 120 and the box portion 110 .

[0291] In this technical solution, the aforementioned dispensing unit 100 may also include a hinge portion 130 arranged between the aforementioned cover portion 120 and the aforementioned box body portion 110, so that the cover portion 120 can be hinged to the box body portion 110 through the hinge portion 130, so as to facilitate opening or covering the aforementioned liquid injection port by rotating relative to the cover portion 120, which is beneficial for ensuring the operational convenience of the dispensing unit 100 while ensuring the reliability of the connection between the box body portion 110 and the cover portion 120.

[0292] As shown in Figures 2, 4, 6 to 9, in some examples, the hinge portion 130 includes: a connecting member 131, which is provided on the cover body 120, and the connecting member 131 is formed with an axis hole 1311; a rotating shaft 132, which is provided on the box body 110, and the rotating shaft 132 is rotatably passed through the axis hole 1311.

[0293] In this technical solution, the aforementioned hinged portion 130 may include a connecting piece 131 and a rotating shaft 132, wherein the aforementioned connecting piece 131 is arranged on the aforementioned cover portion 120 and is formed with an axis hole 1311, and the aforementioned rotating shaft 132 is arranged on the aforementioned box body portion 110 and can be rotatably passed through the connecting piece 131 through the aforementioned axis hole 1311, so that based on the aforementioned setting, the box body portion 110 can be pivoted relative to the cover portion 120 to realize the opening and closing of the liquid injection port, and at the same time, it can avoid the structural complexity of the hinged portion 130 being too large, which is conducive to further reducing the production difficulty and manufacturing cost of the dosing unit 100, and thereby further reducing the use cost of the dosing unit 100.

[0294] As shown in Figures 3, 7 and 9, in some feasible examples, the aforementioned rotating shaft 132 and the aforementioned box body 110 can be an integrated structure, and the aforementioned connecting member 131 and the aforementioned cover body 120 can be an integrated structure, which is beneficial to improve the assembly convenience of the box body 110, the cover body 120 and the hinged part 130, and improve the structural compactness of the delivery unit 100.

[0295] As shown in Figure 7, in some feasible examples, the number of the aforementioned rotating shafts 132 can be two, and the aforementioned two rotating shafts 132 are coaxially and relatively arranged on the aforementioned box body 110. It can be understood that, when the aforementioned rotating shaft 132 and the aforementioned box body 110 can be an integrated structure, the aforementioned rotating shaft 132 can be a cylindrical structure protruding from the box body 110; accordingly, the number of the aforementioned through-axis holes 1311 can also be two, and the two through-axis holes 1311 are respectively located on two sides of the connecting member 131 away from each other, and each of the aforementioned rotating shafts 132 is rotatably passed through a through-axis hole 1311; thus, based on the aforementioned setting, it is beneficial to further improve the smoothness of the rotation of the cover body 120 relative to the box body 110, and improve the connection reliability between the cover body 120 and the box body 110.

[0296] It is understandable that the aforementioned shaft hole 1311 can be a through hole or a blind hole opened in the aforementioned connecting member 131, which can match the aforementioned rotating shaft 132.

[0297] As shown in FIG. 4 , FIG. 6 and FIG. 9 , in some examples, the connecting member 131 has a notch 1312 , and the notch 1312 is located around the through-shaft hole 1311 and communicates with the through-shaft hole 1311 .

[0298] In this technical solution, the aforementioned connecting member 131 can be formed with a notch 1312 located on the circumferential side of the through-axis hole 1311, and the aforementioned notch 1312 is communicated with the aforementioned through-axis hole 1311. Therefore, based on the aforementioned setting, during the assembly process of the connecting member 131 and the rotating shaft 132, it is convenient for the rotating shaft 132 to pass through the aforementioned notch 1312 and into the through-axis hole 1311, which is conducive to further improving the assembly convenience of the hinged part 130, reducing the possibility of damage to the hinged part 130 during the assembly process, improving the production yield of the delivery unit 100, and helping to further reduce the use cost of the delivery unit 100.

[0299] As shown in Figures 3 and 6 to 9, in some examples, at least a portion of the circumferential wall of the rotating shaft 132 is an axial plane 1321, and the axial plane 1321 is parallel to the axial direction of the rotating shaft 132. The notch 1312 cooperates with the axial plane 1321 to make the rotating shaft 132 suitable for being inserted into the through-shaft hole 1311.

[0300] In this technical solution, at least part of the circumferential wall of the aforementioned rotating shaft 132 can be set as an axial plane 1321 parallel to the circumference of the rotating shaft 132, so that based on the aforementioned setting, the minimum radial dimension of the rotating shaft 132 can be reduced. During the assembly process of the connecting member 131 and the rotating shaft 132, the aforementioned rotating shaft 132 can utilize the aforementioned axial plane 1321 to cooperate with the mouth wall of the aforementioned notch 1312 to further facilitate the rotating shaft 132 to penetrate the aforementioned through-shaft hole 1311, which is beneficial to further improve the assembly convenience of the hinged part 130, reduce the possibility of damage to the hinged part 130 during the assembly process, and improve the production yield of the delivery unit 100.

[0301] As shown in FIG9 , by way of example, the chord length L of the notch 1312 can be set to be smaller than the diameter of the shaft 132 and approximately equal to the height H of the cross section of the shaft 132 perpendicular to the axial plane 1321. In some embodiments, the chord length L is slightly smaller than the height H. It is understood that because the notch 1312 is located on the circumferential side of the through-shaft hole 1311 and is connected to the through-shaft hole 1311, the opening width of the notch 1312 can be represented by the chord length L of the through-shaft hole 1311 corresponding to the notch 1312. Correspondingly, because the shaft 132 is formed with the axial plane 1321, the relatively small radial dimension of the shaft 132 can be represented by the height H of the cross section of the shaft 132 perpendicular to the axial plane 1321. Therefore, the chord length L of the notch 1312 can be set to be approximately equal to the height H perpendicular to the axial plane 1321 in the cross section of the rotating shaft 132, preferably slightly smaller than the height H, so that the rotating shaft 132 can pass through the notch 1312 to pass into the through-shaft hole 1311, and the chord length L of the notch 1312 can be set to be smaller than the diameter of the rotating shaft 132, thereby reducing the probability of the rotating shaft 132 escaping from the through-shaft hole 1311 through the notch 1312 during rotation, thereby ensuring the reliability of the hinged portion 130.

[0302] It can be understood that the number of the aforementioned axial planes 1321 can be greater than or equal to one. As shown in Figure 5, the number of the aforementioned axial planes 1321 can be two, and the two aforementioned axial planes 1321 are arranged parallel to each other on both sides, which is conducive to further reducing the minimum radial dimension of the rotating shaft 132 and facilitating the assembly of the rotating shaft 132.

[0303] It can be understood that when the number of axial planes 1321 is one, since the outer peripheral wall on the rotating shaft 132 opposite to the axial plane 1321 is an arc surface, the height H perpendicular to the axial plane 1321 in the cross section of the rotating shaft 132 is non-constant. Based on this situation, the chord length L of the aforementioned notch 1312 is approximately equal to the height H perpendicular to the axial plane 1321 in the cross section of the rotating shaft 132. The chord length L of the notch 1312 can be approximately equal to the maximum height H perpendicular to the axial plane 1321 in the cross section of the rotating shaft 132 to ensure the passability of the notch 1312.

[0304] As shown in Figures 17 to 19, in some feasible examples, when the box body 110 includes a liquid storage box 111 and a box cover 112, the box cover 112 is detachably connected to the liquid storage box 111, the liquid storage cavity 1101 is used to accommodate fluid or a fluid container 10', and the box cover 112 is detachably provided on the liquid storage box 111; the delivery system 10 also includes: a delivery pipeline 500, the input end of the delivery pipeline 500 is located in the liquid storage cavity 1101, and when a fluid container 10' is provided in the liquid storage cavity 1101, the input end of the delivery pipeline 500 is connected to the fluid container 10'.

[0305] In this technical solution, the liquid storage box 111 and the box cover 112 of the box body 110 of the dispensing unit 100 are detachably connected. By removing the box cover 112 from the liquid storage box 111, the covered area of ​​the liquid storage cavity 1101 can be reduced, thereby improving the spatial openness and structural permeability of the liquid storage cavity 1101, thereby facilitating the insertion of fluid or a fluid container 10' into the liquid storage cavity 1101 in actual applications. The delivery system 10 may further include a delivery pipeline 500, the input end of which is located in the aforementioned liquid storage chamber 1101. Thus, when the liquid storage chamber 1101 contains fluid, the input end of the delivery pipeline 500 can be directly connected to the fluid in the liquid storage chamber 1101 and guide the fluid to flow outside the liquid storage chamber 1101. When a fluid container 10' is provided in the liquid storage chamber 1101, the input end of the delivery pipeline 500 is connected to the fluid container 10'. Thus, the input end of the delivery pipeline 500 can receive the fluid contained in the fluid container 10' and guide the fluid to flow outside the liquid storage chamber 1101. Based on the aforementioned setting, the types of objects contained in the liquid storage chamber 1101 can be expanded, thereby improving the adaptability of the delivery system 10 to different types of cleaning agents, which is beneficial to improving the user experience of the product.

[0306] It is understood that when the dispensing system 10 is applied to a cleaning device, the aforementioned fluid may be, but is not limited to, a detergent. Accordingly, the aforementioned fluid container 10' may be a detergent container suitable for machine washing, such as an ink cartridge for a cartridge-type detergent or a capsule for a capsule-type detergent. Taking the case where the dispensing system 10 is applied to a clothing processing device as an example, the output end of the aforementioned dispensing conduit 500 may be used to connect to the clothing processing chamber of the clothing processing device to guide the fluid connected to the aforementioned input end into the clothing processing chamber. When the dispensing system 10 includes the aforementioned pumping unit 200, the output end of the dispensing conduit 500 may be connected to the aforementioned pumping unit 200, so as to connect to the aforementioned clothing processing chamber through the aforementioned pumping unit 200.

[0307] It is understood that, as shown in FIG18 , when the fluid container 10′ needs to be placed in the liquid storage chamber 1101, the box cover 112 can be removed first, and then the fluid container 10′ can be placed and the delivery pipeline 500 can be docked. It should be noted that, as shown in FIG17 and FIG18 , when the fluid container 10′ is placed in the liquid storage chamber 1101, the box cover 112 can be further installed on the liquid storage box 111 to cover the liquid storage chamber 1101, or the box cover 112 can be omitted to keep the liquid storage chamber 1101 open. The size of the fluid container 10′ can be adjusted based on its actual volume. For example, if the fluid container 10′ is relatively large and easily interferes with the installation position of the box cover 112, the box cover 112 can be omitted to avoid structural damage. Conversely, if the fluid container 10′ is relatively small, the box cover 112 can be installed to ensure a stable environment inside the liquid storage chamber 1101 and a safe and reliable fluid delivery process.

[0308] As shown in FIG. 17 to FIG. 19 , in some feasible examples, the liquid amount detection unit 300 includes: a negative pressure sensor 320 for detecting the pressure in the delivery pipeline 500 .

[0309] In this technical solution, the aforementioned liquid quantity detection unit 300 may include a negative pressure sensor 320, which is used to detect the pressure in the aforementioned delivery pipeline 500, thereby determining the liquid remaining amount in the liquid storage chamber 1101 based on the detected pressure. Based on the aforementioned setting, it is beneficial to avoid the liquid quantity detection unit 300 from directly contacting the liquid in the liquid storage chamber 1101. Accordingly, it is convenient to arrange the liquid quantity detection unit 300 in the part of the delivery pipeline 500 outside the liquid storage chamber 1101, so as to improve the openness of the installation position of the liquid quantity detection unit 300 and improve the convenience of line connection. Accordingly, it can also reduce the occupation of the internal space of the liquid storage chamber 1101 by the liquid quantity detection unit 300, and can increase the effective volume of the liquid storage chamber 1101.

[0310] It is understandable that, in the case where the liquid storage cavity 1101 contains the fluid container 10 ′, the residual liquid amount in the liquid storage cavity 1101 refers to the residual liquid amount in the fluid container 10 ′.

[0311] As shown in Figures 18 and 19, in some feasible examples, the delivery pipeline 500 includes: a connector 510, which is arranged in the liquid storage cavity 1101 and is used to adapt to the container mouth of the fluid container 10'; a suction tube 520, one end of which is detachably connected to the connector 510 and the other end of which is formed with an input end.

[0312] In this technical solution, the delivery pipeline 500 may include a joint portion 510 and a suction tube 520, wherein the joint portion 510 is arranged in the aforementioned liquid storage chamber 1101 and is used to adapt to the container mouth of the aforementioned fluid container 10', and the suction tube 520 and the joint portion 510 are in a detachable connection relationship, and when the suction tube 520 is connected to the joint portion 510, the end of the suction tube 520 away from the joint portion 510 forms an input end of the delivery pipeline 500, and accordingly, when the suction tube 520 is separated from the joint portion 510, the joint portion 510 forms an input end of the delivery pipeline 500. Therefore, based on the above-mentioned arrangement, when the liquid storage chamber 1101 contains the above-mentioned fluid, the above-mentioned suction tube 520 can be set on the above-mentioned joint portion 510, so as to increase the pipeline length of the delivery pipeline 500 in the liquid storage chamber 1101, thereby expanding the distribution range of the delivery pipeline 500 in the liquid storage chamber 1101; when the liquid storage chamber 1101 contains the above-mentioned fluid container 10', the above-mentioned suction tube 520 can be removed from the above-mentioned structural portion, so that the joint portion 510 can be connected to the container mouth of the above-mentioned fluid container 10', thereby facilitating the delivery pipeline 500 to guide the fluid in the fluid container 10'.

[0313] It is understood that detergent containers suitable for machine washing, such as ink cartridges or capsules, typically have a threaded or snap-fit ​​connection structure. Accordingly, the connector 510 is adapted to fit within the container opening. This means that the connector 510 has a shape that allows it to connect and cooperate with the connection structure, allowing it to dock with the container opening. In practical applications, the connector 510 and the liquid reservoir 111 can also be detachably connected. Accordingly, there can be multiple connectors 510, each with a different shape. This allows users to easily select a different connector 510 when docking with a fluid container 10' having a different connection structure. As shown in FIG. 19 , in some feasible examples, when the suction tube 520 is connected to the connector 510, the input end of the delivery line 500 is positioned near the bottom wall of the liquid reservoir 1101.

[0314] In this technical solution, when the suction tube 520 is connected to the joint part 510, the input end of the delivery pipeline 500 can be arranged close to the bottom wall of the liquid storage chamber 1101, that is, the end of the suction tube 520 away from the joint part 510 is arranged close to the bottom wall of the liquid storage chamber 1101. Based on the above-mentioned setting, it is convenient for the delivery pipeline 500 to guide the liquid in the bottom area of ​​the liquid storage chamber 1101, which is beneficial to improve the utilization rate of the detergent in the liquid storage chamber 1101 and reduce the loss of detergent in the liquid storage chamber 1101 during the clothing processing process, further reduce the cost of clothing processing, and improve the user experience of the product.

[0315] It can be understood that, as shown in Figure 19, the suction tube 520 can be an L-shaped tube. In actual applications, the shape of the suction tube 520 can be set according to actual needs, that is, the suction tube 520 can also be a straight tube, a curved tube, etc., and no further restrictions are made here.

[0316] As shown in Figures 1 to 19, according to the first aspect of an embodiment of the present disclosure, a delivery system 10 is proposed, including: a delivery unit 100, including a box body 110, the box body 110 including a liquid storage box 111 and a box cover 112, the liquid storage box 111 is formed with a liquid storage cavity 1101, the liquid storage cavity 1101 is used to accommodate fluid or a fluid container 10', and the box cover 112 is detachably provided on the liquid storage box 111; a delivery pipeline 500, the input end of the delivery pipeline 500 is located in the liquid storage cavity 1101, and when a fluid container 10' is provided in the liquid storage cavity 1101, the input end of the delivery pipeline 500 is connected to the fluid container 10'.

[0317] The dispensing system 10 provided in the embodiment of the present disclosure includes a dispensing unit 100 and a dispensing pipeline 500, wherein the dispensing unit 100 includes a box body 110, and the box body 110 further includes a liquid storage box 111 and a box cover 112. The liquid storage box 111 is formed with a liquid storage cavity 1101 to provide a receiving space for the fluid or fluid container 10' in practical applications. The box cover 112 is detachably provided on the liquid storage box 111, so that by removing the box cover 112 from the liquid storage box 111, the covered area of ​​the liquid storage cavity 1101 can be reduced, the spatial openness and structural permeability of the liquid storage cavity 1101 can be improved, and the fluid or fluid container 10' can be easily inserted into the liquid storage cavity 1101 in practical applications. The input end of the delivery pipeline 500 is located in the aforementioned liquid storage chamber 1101, so that when the liquid storage chamber 1101 contains fluid, the input end of the delivery pipeline 500 can be directly connected to the fluid in the liquid storage chamber 1101 and guide the fluid to flow outside the liquid storage chamber 1101; when a fluid container 10' is provided in the liquid storage chamber 1101, the input end of the delivery pipeline 500 is connected to the fluid container 10', so that the input end of the delivery pipeline 500 can receive the fluid contained in the fluid container 10' and guide the fluid to flow outside the liquid storage chamber 1101.

[0318] In actual applications, the dispensing system 10 provided by the embodiment of the present disclosure can be applied to clothing processing equipment, such as washing machines, washer-dryers, etc.; accordingly, the aforementioned fluid can be but is not limited to laundry detergent, softener, detergent, disinfectant and other cleaning agents, and the aforementioned fluid container 10' can be a cartridge for ink cartridge-type cleaning agent or a capsule for capsule-type cleaning agent, etc., which is a cleaning agent container suitable for machine washing.

[0319] Taking the above-mentioned dispensing system 10 as an example when it is applied to a clothing processing device, the clothing processing device usually has a clothing processing chamber, and the above-mentioned liquid storage chamber 1101 or the fluid container 10' in the liquid storage chamber 1101 can be connected to the above-mentioned clothing processing chamber through the above-mentioned dispensing pipe 500, that is, the output end of the dispensing pipe 500 can be used to be connected to the above-mentioned clothing processing chamber, so that the detergent in the liquid storage chamber 1101 can be output to the above-mentioned clothing processing chamber through the dispensing pipe 500, so as to participate in the clothing processing process, thereby improving the convenience of detergent dispensing in the clothing processing process, and also helping to improve the accuracy of detergent dispensing, reduce the chance of detergent spillage, and improve the cleanliness and hygiene of the clothing processing process.

[0320] It can be understood that, in actual application, the aforementioned delivery pipeline 500 can be directly or indirectly connected to the aforementioned clothing processing chamber.

[0321] It is understood that, as shown in FIG18 , when the fluid container 10′ needs to be placed in the liquid storage chamber 1101, the box cover 112 can be removed first, and then the fluid container 10′ can be placed and the delivery pipeline 500 can be docked. It should be noted that, as shown in FIG17 and FIG18 , when the fluid container 10′ is placed in the liquid storage chamber 1101, the box cover 112 can be further installed on the liquid storage box 111 to cover the liquid storage chamber 1101, or the box cover 112 can be omitted to keep the liquid storage chamber 1101 open. The size of the fluid container 10′ can be adjusted based on its actual volume. For example, if the fluid container 10′ is relatively large and easily interferes with the installation position of the box cover 112, the box cover 112 can be omitted to avoid structural damage. Conversely, if the fluid container 10′ is relatively small, the box cover 112 can be installed to ensure a stable environment inside the liquid storage chamber 1101 and a safe and reliable fluid delivery process.

[0322] It should be noted that the detergent dispensing device of the clothing processing equipment in the traditional technology usually only has a liquid storage space for accommodating liquid detergent, but the aforementioned liquid storage space does not have an interface for docking detergent cartridges or capsules, so that this type of dispensing device can only receive liquid detergent manually added by the user, that is, this type of dispensing device is only suitable for pouring and filling detergent; or, the aforementioned dispensing device only has an interface for docking detergent cartridges or capsules, but the area where the aforementioned interface is located does not have the ability to hold liquid, so that this type of dispensing device can only be filled with detergent by replacing the cartridge, that is, this type of dispensing device is only suitable for replacing the detergent used in the container; based on the above situation, the clothing processing equipment can often only adopt one detergent filling method, that is, pouring filling or container replacement, which results in a single detergent filling method for the clothing processing equipment, and sometimes it is difficult for users to fill according to the method of using the detergent, resulting in poor convenience of use of the dispensing device, limiting the improvement of the product user experience. The dispensing system 10 provided by the present disclosure is based on the above-mentioned settings, which can facilitate users to adopt different filling methods according to the usage of the detergent, thereby improving the convenience of use of the dispensing system 10 and enhancing the integration of the dispensing system 10. It can make the dispensing system 10 suitable for different detergent filling methods while having a high structural compactness, which can avoid a significant increase in the volume or mass of the clothing processing equipment in actual application, and is conducive to improving the miniaturization and lightweight level of the clothing processing equipment.

[0323] It can be understood that the aforementioned delivery system 10 is well applicable to small-sized clothing processing equipment; small-sized clothing processing equipment generally refers to clothing processing equipment with a clothing processing capacity of less than 3 kg.

[0324] As shown in FIG. 2 , FIG. 1 , and FIG. 4 to FIG. 6 , in some examples, the dispensing unit 100 further includes: a cover body 120 , the box cover 112 is formed with a dispensing port 1102 , and the cover body 120 is movably disposed on the box cover 112 for covering or opening the dispensing port 1102 .

[0325] In this technical solution, the box cover 112 can be formed with a feeding port 1102. When the box cover 112 is set on the liquid storage chamber, the feeding port 1102 is communicated with the aforementioned liquid storage chamber 1101, thereby providing a channel for the user to manually add liquid detergent. The feeding unit 100 can also include a cover body 120, which is movably set on the box cover 112 and can cover or open the aforementioned feeding port 1102 by the user, so that when the feeding system 10 participates in the clothing processing process, the aforementioned cover body can be used to manually add liquid detergent. 120 covers the aforementioned delivery port 1102 so that the liquid storage chamber 1101 has good sealing properties, ensuring the smooth progress of the detergent delivery process, reducing the possibility of detergent spillage, and improving the hygiene and cleanliness of the clothing processing process; accordingly, when detergent needs to be added, the cover body 120 can open the aforementioned delivery port 1102 or the box body 110 connected to the cover body 120 can be removed from the liquid storage box 111 to improve the openness of the liquid storage chamber 1101 and facilitate the detergent filling operation.

[0326] As shown in FIG. 17 to FIG. 19 and FIG. 10 to FIG. 12 , in some examples, the delivery system 10 further includes: a pumping unit 200 connected to the output end of the delivery pipeline 500 .

[0327] In this technical solution, the delivery system 10 may further include a pumping unit 200 connected to the output end of the aforementioned delivery pipeline 500. In actual application, the pumping unit 200 is used to pump fluid from the input end to the output end of the delivery pipeline 500. When the delivery system 10 is applied to a clothing processing device, the pumping unit 200 is used to pump the fluid into the clothing processing chamber. Based on the aforementioned setting, the fluid delivery efficiency of the delivery system 10 can be improved, and the requirements of the delivery system 10 for the setting location can be reduced, thereby improving the space utilization of the clothing processing device and improving the miniaturization and lightweight level of the clothing processing device.

[0328] In some examples, pumping unit 200 includes a peristaltic pump or a plunger pump.

[0329] In this technical solution, the pumping unit 200 may include a peristaltic pump, that is, the pumping unit 200 may use the peristaltic pump to pump the fluid in the liquid storage chamber 1101. It can be understood that the peristaltic pump has good self-priming and sealing properties, thereby improving the pumping unit 200's ability to deliver high-viscosity fluids, facilitating the pumping unit 200 to deliver detergents, and reducing the risk of leakage in the pumping unit 200, thereby improving the cleanliness and reliability of the pumping unit 200.

[0330] Alternatively, the pumping unit 200 may include a plunger pump, that is, the pumping unit 200 may utilize the plunger pump to pump the fluid in the liquid storage chamber 1101. It can be understood that the plunger pump has a higher output pressure and output efficiency, thereby improving the detergent delivery performance of the pumping unit 200, which is beneficial to improving the delivery efficiency of the delivery unit 100.

[0331] As shown in FIG. 17 to FIG. 19 and FIG. 12 , in some examples, the dosing system 10 further includes: a liquid amount detection unit 300 for detecting the remaining liquid in the liquid storage chamber 1101 .

[0332] In this technical solution, the aforementioned dispensing system 10 may also include a liquid quantity detection unit 300, which is used to detect the remaining liquid in the liquid storage chamber 1101, thereby facilitating the user to understand the usage status of the detergent during use, which is conducive to further improving the ease of use of the dispensing system 10.

[0333] It is understandable that, in the case where the liquid storage cavity 1101 contains the fluid container 10 ′, the residual liquid amount in the liquid storage cavity 1101 refers to the residual liquid amount in the fluid container 10 ′.

[0334] In some examples, the liquid volume detection unit 300 includes: a negative pressure sensor 320 for detecting the pressure in the delivery pipeline 500.

[0335] In this technical solution, the aforementioned liquid quantity detection unit 300 may include a negative pressure sensor 320, which is used to detect the pressure in the aforementioned delivery pipeline 500, thereby determining the liquid remaining amount in the liquid storage chamber 1101 based on the detected pressure. Based on the aforementioned setting, it is beneficial to avoid the liquid quantity detection unit 300 from directly contacting the liquid in the liquid storage chamber 1101. Accordingly, it is convenient to arrange the liquid quantity detection unit 300 in the part of the delivery pipeline 500 outside the liquid storage chamber 1101, so as to improve the openness of the installation position of the liquid quantity detection unit 300 and improve the convenience of line connection. Accordingly, it can also reduce the occupation of the internal space of the liquid storage chamber 1101 by the liquid quantity detection unit 300, and can increase the effective volume of the liquid storage chamber 1101.

[0336] As shown in Figure 12, in some feasible examples, the aforementioned liquid quantity detection unit 300 may include a magnetic levitation 310, and the dispensing unit 100 also includes a mounting column 160. The mounting column 160 is located in the liquid storage chamber 1101 and is arranged along the depth direction of the liquid storage chamber 1101. The magnetic levitation 310 is movably mounted on the mounting column 160. Based on the aforementioned setting, the range of movement of the aforementioned magnetic levitation 310 can be constrained to ensure the smooth operation of the magnetic levitation 310.

[0337] It can be understood that when the liquid quantity detection unit 300 includes the aforementioned magnetic levitation 310, the liquid quantity detection unit 300 is also a magnetic levitation 310 type liquid level sensor. Accordingly, when there is liquid in the liquid storage chamber 1101, the magnetic levitation 310 will float on the liquid and rise and fall with the change of liquid level. Accordingly, the magnetic levitation 310 type liquid level sensor can also include components such as magnetic switches for sensing the position of the magnetic levitation 310, and processing components that convert the aforementioned position into liquid quantity information, thereby obtaining the remaining liquid in the liquid storage chamber 1101.

[0338] As shown in FIG. 12 , in some feasible examples, the bottom of the liquid storage chamber 1101 has a recessed area 1101 a , and one end of the mounting post 160 is located in the recessed area 1101 a .

[0339] It can be understood that since the magnetic levitation 310 can float on the liquid, if the amount of liquid in the liquid storage chamber 1101 is small, causing the magnetic levitation 310 to abut the bottom of the liquid storage chamber 1101, the change in the amount of the remaining liquid is difficult to be measured by the liquid amount detection unit 300, thereby reducing the detection accuracy of the liquid amount detection unit 300. Based on the consideration of the above situation, in this technical solution, the bottom of the liquid storage chamber 1101 can have a recessed area 1101a, and the mounting column 160 of the magnetic levitation 310 for positioning the liquid quantity detection unit 300 can be located in the aforementioned recessed area 1101a, thereby achieving local deepening of the liquid storage chamber 1101, increasing the buoyancy of the magnetic levitation 310 at the same depth position, and providing space for the lifting and lowering of the magnetic levitation 310. If the space above the recessed area 1101a in the liquid storage chamber 1101 is regarded as the main space of the liquid storage chamber 1101, then based on the aforementioned setting, when the liquid remaining amount in the main area is small, the magnetic levitation 310 can reflect the change in the liquid remaining amount in the main area by floating in the aforementioned recessed area 1101a, thereby further improving the user experience of the product by improving the detection range and detection accuracy of the liquid quantity detection unit 300.

[0340] In some feasible examples, when the dosing system 10 includes the pumping unit 200 , the input end of the pumping unit 200 is located in the recessed area 1101 a .

[0341] In this technical solution, the input end of the pumping unit 200 can be set to be located in the aforementioned recessed area 1101a, so that based on the aforementioned setting, the pumping device can more fully extract the liquid in the liquid storage chamber 1101, which is beneficial to reduce the liquid loss in the liquid storage chamber 1101 and improve the utilization rate of the liquid in the liquid storage chamber 1101, which is beneficial to reduce the cost of the cleaning process in actual applications.

[0342] As shown in Figures 17 to 19 and Figures 10 to 13, in some examples, the delivery system 10 further includes: a accommodating unit 400, which forms an open accommodating cavity 401, and the box body 110 is movably disposed in the accommodating unit 400 so that the box body 110 can extend or retract into the accommodating cavity 401.

[0343] In this technical solution, the delivery system 10 may further include a accommodating unit 400, wherein the accommodating unit 400 is formed with an open accommodating cavity 401, and the box body 110 is movably connected to the accommodating unit 400 so that the box body 110 can be pulled out or pushed into the accommodating cavity 401. Based on the above-mentioned setting, during the delivery of the cleaning agent by the delivery system 10, the liquid storage box 111 can be retracted into the accommodating cavity 401, and then the delivery system 10 can further utilize the accommodating unit 400 to provide structural protection for the box body 110, so as to improve the stability and reliability of the liquid storage cavity 1101; when the cleaning agent needs to be added or the container needs to be replaced, the liquid storage box 111 can be extended out of the accommodating cavity to facilitate user operation and improve the convenience of cleaning agent filling.

[0344] In practical applications, the accommodating unit 400 may be provided in a housing of the laundry processing apparatus to ensure the stability of the accommodating unit 400 and the dispensing unit 100 .

[0345] As shown in Figures 14 to 16, in some feasible examples, when the dispensing system 10 is applied to a clothing processing device, the accommodating unit 400 is arranged close to the cleaning port 23 of the clothing processing device, and when the box body 110 is retracted into the accommodating cavity 401, the decorative panel portion 140 covers the opening of the accommodating cavity 401 and the cleaning port 23.

[0346] In this technical solution, when the delivery system 10 is applied to a clothing processing device, the aforementioned accommodating unit 400 can be arranged close to the cleaning port 23 of the clothing processing device. It can be understood that the clothing processing device usually has a drainage system or a filtration system 40. Accordingly, a cleaning port 23 corresponding to the cleaning end 41 of the aforementioned drainage system or filtration system 40 will be provided on the housing assembly 20 of the clothing processing device, so that the user can regularly clean the drainage system or filtration system 40 to reduce the chance of blockage of components or pipes. The accommodating unit 400 provided in the embodiment of the present disclosure can be arranged close to the cleaning port 23 of the clothing processing device. Accordingly, when the box body 110 of the dispensing unit 100 is retracted into the accommodating cavity 401 of the accommodating unit 400, the decorative panel portion 140 of the dispensing unit 100 can be arranged to cover the opening of the accommodating cavity 401 and the aforementioned cleaning port 23 at the same time. Therefore, on the one hand, it is possible to avoid arranging an independent cover for the aforementioned cleaning port 23, which is beneficial to reducing the number of parts of the clothing processing device, thereby reducing the production cost and use cost of the clothing processing device, and reducing the possibility of user misoperation; on the other hand, since the dispensing unit 100 is used to hold and dispense detergent during the clothing processing process, the frequency of use is relatively high. The centralized arrangement of the dispensing device and the cleaning port 23 also helps to increase the probability of the user finding the cleaning port 23 during the process of the user dispensing detergent, thereby reminding the user to clean the drainage system or the filter system 40, which is beneficial to reducing the risk of blockage in the drainage system or the filter system 40, thereby improving the user experience of the product.

[0347] It can be understood that the housing assembly 20 of the clothes treating apparatus may include a base 21 and a panel 22 .

[0348] In some feasible examples, the delivery system 10 further includes: a slide rail unit, disposed in the accommodating cavity 401; a slider unit, disposed in the box body 110, and the slider unit is slidably connected to the slide rail unit so that the box body 110 can be slidably extended or retracted into the accommodating cavity 401.

[0349] In this technical solution, the delivery system 10 may further include a slide rail unit and a slider unit, which are respectively arranged in the accommodating cavity 401 of the accommodating unit 400 and on the box body 110 of the delivery unit 100, and the slider unit is slidably connected to the slide rail unit, so that the box body 110 can be slidably extended or retracted into the accommodating cavity 401, which is beneficial to improving the movement stability and smoothness of the box body 110 and improving the operational convenience of the delivery system 10.

[0350] As shown in Figures 9 and 10, in some feasible examples, the accommodating unit 400 is also formed with a first limiting structure 402, and the dispensing unit 100 also includes a second limiting structure 150, which is detachably connected to the first limiting structure 402. When the box body 110 is retracted into the accommodating cavity 401, the second limiting structure 150 is connected to the first limiting structure 402.

[0351] In this technical solution, the aforementioned accommodating unit 400 can be formed with a first limiting structure 402, and the aforementioned delivery unit 100 can also include a second limiting structure 150. When the box body 110 is pushed into the accommodating cavity 401, the second limiting structure 150 is connected to the first limiting structure 402, so that the delivery system 10 can fix the relative position between the accommodating unit 400 and the delivery unit 100 based on the matching relationship between the aforementioned first limiting structure 402 and the aforementioned second limiting structure 150, thereby reducing the possibility of the delivery unit 100 accidentally falling out of the accommodating unit 400 during use.

[0352] It is understandable that the accommodating unit 400 can be used to fix the housing assembly 20 disposed on a cleaning device (eg, a clothes processing device).

[0353] As shown in Figures 12 and 13, in some feasible examples, the aforementioned first limiting structure 402 can be a fixed column, and the aforementioned second limiting structure 150 can be a buckle, and the aforementioned buckle can be detachably connected to the aforementioned fixed column, so that the first limiting structure 402 and the second limiting structure 150 can be fixed by snapping.

[0354] As shown in Figures 17 to 19, in some examples, the delivery pipeline 500 includes: a connector 510, which is arranged in the liquid storage cavity 1101 and is used to adapt to the container mouth of the fluid container 10'; a suction tube 520, one end of which is detachably connected to the connector 510 and the other end of which is formed with an input end.

[0355] In this technical solution, the delivery pipeline 500 may include a joint portion 510 and a suction tube 520, wherein the joint portion 510 is arranged in the aforementioned liquid storage chamber 1101 and is used to adapt to the container mouth of the aforementioned fluid container 10', and the suction tube 520 and the joint portion 510 are in a detachable connection relationship, and when the suction tube 520 is connected to the joint portion 510, the end of the suction tube 520 away from the joint portion 510 forms an input end of the delivery pipeline 500, and accordingly, when the suction tube 520 is separated from the joint portion 510, the joint portion 510 forms an input end of the delivery pipeline 500. Therefore, based on the above-mentioned arrangement, when the liquid storage chamber 1101 contains the above-mentioned fluid, the above-mentioned suction tube 520 can be set on the above-mentioned joint portion 510, so as to increase the pipeline length of the delivery pipeline 500 in the liquid storage chamber 1101, thereby expanding the distribution range of the delivery pipeline 500 in the liquid storage chamber 1101; when the liquid storage chamber 1101 contains the above-mentioned fluid container 10', the above-mentioned suction tube 520 can be removed from the above-mentioned structural portion, so that the joint portion 510 can be connected to the container mouth of the above-mentioned fluid container 10', thereby facilitating the delivery pipeline 500 to guide the fluid in the fluid container 10'.

[0356] It is understood that detergent containers suitable for machine washing, such as ink cartridges or capsules, typically have a threaded or snap-fit ​​connection structure at their openings. Accordingly, the connector 510 is adapted to fit within the container opening. This means that the connector 510 has a shape that allows it to connect and cooperate with the connection structure, allowing it to dock with the container opening. In practical applications, the connector 510 and the liquid storage box 111 can also be detachably connected. Accordingly, there can be multiple connectors 510, each with a different shape. This facilitates user selection of different connectors 510 when docking with fluid containers 10' having different connection structures.

[0357] As shown in FIG. 19 , in some examples, when the suction tube 520 is connected to the joint portion 510 , the input end is arranged close to the bottom wall of the liquid storage chamber 1101 .

[0358] In this technical solution, when the suction tube 520 is connected to the joint part 510, the input end of the delivery pipeline 500 can be arranged close to the bottom wall of the liquid storage chamber 1101, that is, the end of the suction tube 520 away from the joint part 510 is arranged close to the bottom wall of the liquid storage chamber 1101. Based on the above-mentioned setting, it is convenient for the delivery pipeline 500 to guide the liquid in the bottom area of ​​the liquid storage chamber 1101, which is beneficial to improve the utilization rate of the detergent in the liquid storage chamber 1101 and reduce the loss of detergent in the liquid storage chamber 1101 during the clothing processing process, further reduce the cost of clothing processing, and improve the user experience of the product.

[0359] It can be understood that, as shown in Figure 19, the suction tube 520 can be an L-shaped tube. In actual applications, the specific shape of the suction tube 520 can be set according to actual needs, that is, the suction tube 520 can also be a straight tube, a curved tube, etc., and no further restrictions are made here.

[0360] As shown in FIG. 2 to FIG. 6 , the cover 120 has at least two operating ends 1201 . When the cover 120 covers the loading port 1102 , an operating space 1202 is formed between each operating end 1201 and the box body 110 .

[0361] In this technical solution, the aforementioned cover body 120 has an operating end 1201. In actual application, the aforementioned operating end 1201 can be used to withstand the driving force, which is the external force used to drive the cover body 120 to move relative to the box body 110 to realize the opening or closing of the liquid injection port. For example, when the user manually operates the cover body 120, the aforementioned operating end 1201 can be used to contact the operator's hand and withstand the driving force applied by the operator's hand; accordingly, when the aforementioned cover body 120 covers the aforementioned injection port 1102, an operating space 1202 is formed between the aforementioned operating end 1201 and the aforementioned box body 110. The aforementioned operating space 1202 can provide a passable space for the user's hand to approach and contact the aforementioned operating end 1201, thereby facilitating the user to operate the cover body 120.

[0362] The number of the aforementioned operating ends 1201 is at least two, and when the cover body 120 covers the injection port 1102, an operating space 1202 is formed between each operating end 1201 and the box body 110, so that the user's hand can contact multiple parts of the cover body 120 at the same time (for example: opposite sides, which is convenient for the user to hold), and the aforementioned driving force can be applied to multiple parts of the cover body 120 at the same time, so that during the operation of switching the injection port from a covered state to an open state, on the one hand, it can be beneficial to increase the contact area between the cover body 120 and the user's hand, expand the feasible contact orientation between the cover body 120 and the user's hand, thereby improving the user's force application convenience during operation, reducing the difficulty of opening the injection port 1102, and improving the product's user experience; on the other hand, it is also beneficial to prevent the cover body 120 from being subjected to a more concentrated driving force, improve the force dispersion and balance of the cover body 120, thereby reducing the probability of damage to the cover body 120 in actual application, and reducing the maintenance and use costs of the injection unit 100.

[0363] It can be understood that the aforementioned at least two operating ends 1201 can be at least two different ends of the aforementioned cover body 120. For example, when the aforementioned cover body 120 is a plate-like structure, the aforementioned operating end 1201 can be a plate end in the length direction or width direction of the aforementioned plate-like structure. The aforementioned at least two operating ends 1201 can be adjacent to each other or can be spaced apart from each other.

[0364] For example, as shown in FIG4 , the cover body 120 can be a generally rectangular plate-like structure (in some embodiments, the cover body 120 is a square plate-like structure), so that the cover body 120 has four ends in the length and width directions. Thus, for the cover body 120 with a rectangular plate-like structure, the number of the aforementioned operating ends 1201 can be greater than or equal to two and less than or equal to four. Taking into account the connection between the cover body 120 and the box body 110, the number of operating ends 1201 of the cover body 120 with a rectangular plate-like structure can be less than or equal to three, that is, in actual application, one end of the cover body 120 in the length or width direction can be used to connect to the box body 110. It can be understood that the shape of the cover body 120 can be, but is not limited to, a rectangular plate-like structure, and can also be other polygonal plate-like structures, such as a triangular plate-like structure, a pentagonal plate-like structure, a hexagonal plate-like structure, etc. Accordingly, the number of operating ends 1201 can also be set in combination with the specific shape of the cover body 120 and actual needs.

[0365] It should be noted that some conventional dispensing units 100 typically include a box body and a lid body. The box body defines an open liquid storage space, and the lid body is used to cover or open the opening of the liquid storage space. Furthermore, the box body often has a small notch structure on one side of the lid body. When the lid body covers the opening, if a user needs to open the opening, they can only insert a single fingernail through the small notch structure on the side of the lid body. As a result, the user can often only apply force to the lid body from a single position. This is not only difficult to operate and has a poor user experience, but also, due to the cramped space, it is not easy for the user to control the direction and magnitude of the force applied, which can easily cause damage to the lid body. The dispensing unit 100 provided in the present embodiment, based on the above-mentioned configuration, can increase the contact area between the lid body 120 and the user's hand, expand the possible contact directions between the lid body 120 and the user's hand, improve the user's convenience in applying force during operation, and facilitate improving the force distribution and balance of the lid body 120, thereby reducing the chance of damage to the lid body 120 during actual use.

[0366] As shown in FIG. 2 to FIG. 6 , in some feasible examples, the cover portion 120 and the box body portion 110 have the same width, and the cover portion 120 has an operating end 1201 .

[0367] The aforementioned cover body 120 has an operating end 1201. In actual application, the aforementioned operating end 1201 can be used to withstand the driving force, which is the external force used to drive the cover body 120 to move relative to the box body 110 to realize the opening or closing of the liquid injection port. For example, when the user manually operates the cover body 120, the aforementioned operating end 1201 can be used to contact the operator's hand and withstand the driving force applied by the operator's hand; accordingly, when the aforementioned cover body 120 covers the aforementioned injection port 1102, an operating space 1202 is formed between the aforementioned operating end 1201 and the aforementioned box body 110. The aforementioned operating space 1202 can provide a passable space for the user's hand to approach and contact the aforementioned operating end 1201, thereby facilitating the user to operate the cover body 120.

[0368] At the same time, the width of the cover 120 is consistent with the width of the box body 110, which allows the cover 120 to have a relatively high width, thereby facilitating the user's hand to operate with a wider opening, thereby reducing the possibility of interference between the user's fingers during operation, and further improving the ease of operation of the cover 120. Accordingly, when the cover 120 is relatively large, the user can grasp the cover 120 to operate it, that is, the user can apply force to each operating end 1201 with two fingers, further improving the ease of operation of the cover 120.

[0369] It can be understood that the width of the aforementioned cover portion 120 is consistent with the width of the box body portion 110, that is, the cover portion 120 has a width similar to that of the box body portion 110 (for example, the same or slightly smaller width), and has an overall shape that is adapted to the box body portion 110 (for example: an overall shape consistent with the box body portion 110), thereby ensuring that the cover portion 120 has a higher width for user operation while making the dispensing unit 100 have a higher aesthetics.

[0370] For example, the width of the cover 120 can be greater than or equal to 0.8 times the width of the box body 110 and less than or equal to the width of the box body 110. This, on the one hand, allows the width of the box body 110 to be highly consistent with the width of the cover 120, thereby facilitating the user's hand-stretching operation and further improving the ease of operation of the cover 120. On the other hand, it also prevents the width of the cover 120 from being too large, thereby ensuring the compactness of the dispensing unit 100 and improving the aesthetics of the dispensing unit 100. For example, the width of the cover 120 can be, but is not limited to, 0.8 times, 0.85 times, 0.9 times, 0.9 times, 1 times, etc., of the width of the box body 110. The width ratio between the cover 120 and the box body 110 can be specifically set according to actual needs and is not further limited here.

[0371] It can be understood that, when the cover portion 120 is a plate-like structure, the operating end 1201 can be a plate end in the width direction of the plate-like structure.

[0372] It should be noted that some conventional dispensing units 100 typically include a box body and multiple covers. The box body has multiple open liquid storage spaces, and the covers are used to cover or open the openings of the aforementioned liquid storage spaces one by one. As a result, the size of the covers is often smaller than the box body, and the box body typically has a small notch structure on one side corresponding to the cover. When the cover covers the aforementioned opening, if the user needs to open the aforementioned opening, they can only insert a single fingernail through the aforementioned small notch structure on the side of the cover. This is not only difficult to operate and has a poor user experience, but also, due to the cramped space, it is not easy for the user to control the direction and magnitude of the force applied, which can easily cause damage to the cover. Based on the above-mentioned configuration, the dispensing unit 100 provided in the embodiment of the present disclosure can increase the width of the cover portion 120, thereby facilitating the contact area between the cover portion 120 and the user's hand, making it easier for the user to apply force during operation, thereby reducing the chance of damage to the cover portion 120 in actual use.

[0373] In some feasible examples, the aforementioned operating end 1201 may be provided with anti-slip grooves to further facilitate the user to apply force to the cover body 120.

[0374] In some feasible examples, the length of the aforementioned operating space 1202 is greater than or equal to the length of the aforementioned operating end 1201, so that the operating space 1202 can correspond to the entire side of the cover body 120, expand the distribution range of the operating space 1202, and further improve the operating convenience of the cover body 120. It can be understood that the length of the aforementioned operating end 1201 is also the dimension of the operating end 1201 in the extension direction. Taking the case where the cover body 120 is a rectangular plate structure as an example, if the aforementioned operating end 1201 is one end in the length direction of the rectangular plate structure, then the operating end 1201 corresponds to the long side of the rectangular plate structure. Accordingly, the operating end 1201 extends along the length direction of the rectangular plate structure. Similarly, if the operating end 1201 is one end in the length direction of the rectangular plate structure, then the operating end 1201 extends along the width direction of the rectangular plate structure. Accordingly, the length direction of the aforementioned operating space 1202 is consistent with the length direction of the aforementioned operating end 1201.

[0375] As shown in FIG. 2 , FIG. 1 , FIG. 4 and FIG. 6 , in some examples, there are two operating ends 1201 , and the two operating ends 1201 face away from each other.

[0376] In this technical solution, the number of the aforementioned operating ends 1201 can be two, and the two aforementioned operating ends 1201 are separated from each other, that is, the two ends of the cover body 120 that are separated from each other can serve as the aforementioned two operating ends 1201. Based on the aforementioned setting, the spacing distance between the aforementioned two operating ends 1201 can be expanded, and then while being able to facilitate the user to apply force to different parts of the cover body 120 at the same time, the force balance of the cover body 120 during use is further improved, which is beneficial to further reduce the chance of damage to the cover body 120 and improve the convenience of opening the injection port 1102.

[0377] It is understandable that, when the two operating ends 1201 face away from each other, when the cover 120 covers the aforementioned delivery port 1102 , two operating spaces 1202 will be correspondingly formed between the cover 120 and the box body 110 .

[0378] It is understood that in actual use, the size of the cover 120 can be set according to actual needs. When the cover 120 is relatively small, the user can operate the cover 120 with a single finger. Based on the above configuration, the distance between the two operating spaces 1202 can be relatively large, thereby facilitating the user's hand to operate with a larger opening, thereby reducing the possibility of interference between the user's fingers during operation, and further improving the ease of operation of the cover 120. Accordingly, when the cover 120 is relatively large, the user can grasp the cover 120 to operate it, that is, the user can apply force to each operating end 1201 with two fingers, which further improves the ease of operation of the cover 120.

[0379] In some feasible examples, the cover portion 120 has a width similar to that of the box body portion 110 (for example, the same or slightly smaller width), and has an overall shape that is compatible with the box body portion 110 (for example: an overall shape consistent with the box body portion 110), thereby ensuring that the cover portion 120 has a higher width for user operation while making the dispensing unit 100 have a higher aesthetics.

[0380] In some feasible examples, the distance between the two operating ends 1201 that are separated from each other is adapted to the width of the box body 110. For example, the distance between the two operating ends 1201 that are separated from each other can be greater than or equal to 0.5 times the width of the box body 110, and less than or equal to 0.95 times the width of the box body 110. On the one hand, this can make the distance between the two operating ends 1201 that are separated from each other larger, increase the span between the operating ends 1201 and the overall width of the cover body 120, thereby facilitating the user's hand-stretching operation and further improving the operational convenience of the cover body 120. On the other hand, it can also avoid the width of the cover body 120 being too large, which is conducive to ensuring the structural compactness of the delivery unit 100 and improving the aesthetics of the delivery unit 100. For example, the distance between the two operating ends 1201 facing away from each other can be but not limited to 0.55 times, 0.6 times, 0.7 times, 0.8 times, 0.9 times, etc., of the width of the box body 110. The aforementioned distance can be set according to actual needs and is not limited here.

[0381] As shown in Figures 2 to 3, in some examples, the box body 110 is formed with a groove 1103, and the delivery port 1102 is arranged in the groove 1103. When the cover body 120 covers the delivery port 1102, the cover body 120 is located in the groove 1103, and an operating space 1202 is defined in the groove 1103.

[0382] In this technical solution, the box body 110 may be formed with a groove 1103, and the delivery port 1102 may be formed in the groove 1103, that is, the groove 1103 and the liquid storage chamber 1101 may be arranged adjacent to each other and communicate with each other. When the cover 120 covers the delivery port 1102, the cover 120 is located in the groove 1103 and defines the operating space 1202 in the groove 1103, thereby avoiding the cover 120 from protruding from the box body 110, improving the structural concealment of the cover 120 when covering the delivery port 1102, and thus improving the aesthetics of the delivery unit 100 and further enhancing the user experience of the product. On the other hand, it can also reduce the possibility of external structures contacting the cover 120, reduce the probability of the delivery port 1102 being accidentally opened, and help to further avoid damage to the cover 120, providing further protection for reducing the use cost of the delivery unit 100.

[0383] As shown in Figures 2 to 3, in some feasible examples, the portion of the box body 110 corresponding to the operating end 1201 may be formed with an opening, and the opening is connected to the groove 1103. Accordingly, when the cover body 120 covers the delivery port 1102, the opening is connected to the operating space 1202, thereby facilitating the passability of the operating space 1202, and further facilitating the user's hand to contact the operating end 1201 of the cover body 120 through the operating space 1202, thereby further improving the convenience of the opening operation of the delivery port 1102.

[0384] As shown in Figures 2 to 3, in some examples, the loading port 1102 is formed on the bottom wall of the groove 1103. When the cover 120 covers the loading port 1102, the side of the cover 120 away from the loading port 1102 is flush with the side of the box body 110.

[0385] In this technical solution, the aforementioned delivery port 1102 can be formed on the bottom wall of the aforementioned groove 1103. It can be understood that the aforementioned groove 1103 is an open groove, and the bottom wall of the aforementioned groove 1103 is also the groove wall opposite to the aforementioned groove. When the aforementioned cover body 120 covers the aforementioned delivery port 1102, one side of the cover body 120 can abut against the bottom wall of the aforementioned groove 1103 to achieve coverage of the aforementioned delivery port 1102. Accordingly, the side of the cover body 120 away from the delivery port 1102 can be arranged to be aligned with the box body 1103. For example, it is flush with the side of the box body 110 on which the aforementioned groove 1103 is formed. Then, when the aforementioned cover body 120 covers the aforementioned delivery port 1102, the side of the delivery unit 100 on which the aforementioned cover body 120 is provided can have a higher surface flatness. On the one hand, it is beneficial to improve the shape matching between the cover body 120 and the groove 1103, and further improve the aesthetics of the delivery unit 100. On the other hand, it is also beneficial to further enhance the structural compactness of the delivery unit 100 and enhance the miniaturization level of the delivery unit 100.

[0386] It can be understood that by opening the aforementioned delivery port 1102 on the bottom wall of the aforementioned groove 1103, the aforementioned delivery port 1102 can also be directed towards the notch of the aforementioned groove 1103, so that when the cover body 120 opens the aforementioned delivery port 1102, it can be further convenient for the operator to inject the cleaning agent into the aforementioned delivery port 1102, which is conducive to further improving the ease of use of the delivery unit 100.

[0387] As shown in Figures 2 to 8, in some examples, the cover body 120 includes a main plate segment 121, a first curved plate segment 122 and a second curved plate segment 123, and the main plate segment 121 is connected between the first curved plate segment 122 and the second curved plate segment 123; the groove 1103 includes a main groove segment 1103a, a first side groove segment 1103b and a second side groove segment 1103c, and the main groove segment 1103a is located between the first side groove segment 1103b and the second side groove segment 1103c; wherein, the shape of the main plate segment 121 is adapted to the shape of the main groove segment 1103a, and the first curved plate segment 122 and the second curved plate segment 123 are respectively consistent with the curvature at the corresponding positions of the box body 110.

[0388] In this technical solution, the aforementioned cover body 120 may include a first arc-shaped plate segment 122, a main body plate segment 121 and a second arc-shaped plate segment 123 connected in sequence. Correspondingly, the aforementioned groove 1103 may include a first side groove segment 1103b, a main body groove segment 1103a and a second side groove segment 1103c connected in sequence. The aforementioned first arc-shaped plate segment 122, the main body plate segment 121 and the second arc-shaped plate segment 123 correspond to the aforementioned first side groove segment 1103b, the main body groove segment 1103a and the second side groove segment 1103c, respectively. That is, when the aforementioned cover body 120 covers the aforementioned loading port 1102, the first arc-shaped plate segment 122 is located in the aforementioned first side groove segment 1103b, and the main body plate segment 121 is located in the aforementioned 21 is located in the main groove section 1103a, and the second arc-shaped plate section 123 is located in the second side groove section 1103c. It can be understood that the aforementioned delivery port 1102 can be opened on the bottom wall of the aforementioned main groove section 1103a. Accordingly, the cover body 120 can use the main plate section 121 to cover or open the aforementioned delivery port 1102, and based on the aforementioned setting, both ends of the main plate section 121 are arc-shaped plate sections, so that the contour of the outer edge of the cover body 120 can be smoother, which is conducive to reducing the angular structure of the edge of the cover body 120, reducing the risk of scratches when the user operates, further improving the convenience of opening and closing the delivery port 1102, and helping to further improve the aesthetics of the delivery unit 100.

[0389] Among them, the shape of the main plate section 121 can be adapted to the shape of the main groove section 1103a, so that when the cover body 120 covers the delivery port 1102, the main plate section 121 and the main groove section 1103a can be more fitted together, making it convenient to make the main plate section 121 and the corresponding partial groove openings of the main groove section 1103a flush, and reduce the fitting gap between the main plate section 121 and the main groove section 1103a, which is beneficial to improve the aesthetics of the delivery unit 100 while reducing the risk of liquid overflow.

[0390] At the same time, the first curved plate segment 122 and the second curved plate segment 123 can be set to be consistent with the curvature of the corresponding position of the box body 110. It should be noted that the position corresponding to the aforementioned box body 110 and the aforementioned first curved plate segment 122 includes the first side groove segment 1103b, so that the aforementioned first side groove segment 1103b can be a curved groove segment; the position corresponding to the aforementioned box body 110 and the aforementioned first curved plate segment 122 includes the second side groove segment 1103c, so that the aforementioned second side groove segment 1103c can also be a curved groove segment; and based on the aforementioned setting, each curved plate segment and the corresponding side groove segment can have a curvature with a high degree of matching, which is conducive to making each curved plate segment more fit against the groove wall of the corresponding side groove segment when the cover body 120 covers the delivery port 1102, thereby reducing the matching gap between the curved plate segment and the corresponding side groove segment, which is conducive to further improving the aesthetics of the delivery unit 100 while reducing the risk of liquid overflow.

[0391] For example, as shown in Figures 2, 3 and 5, the aforementioned delivery port 1102 is formed on the bottom wall of the main groove section 1103a. The bottom wall of the aforementioned main groove section 1103a can be a plane. Correspondingly, the main plate section 121 can be a plate-like structure with high flatness, so that the main groove section 1103a and the main plate section 121 can be matched; the bottom walls of the first side groove section 1103b and the second side groove section 1103c are inclined from the inside to the outside, and can also be arc-shaped walls, and smoothly transition with the bottom wall of the main groove section 1103a, thereby increasing the operating space 1202 of the user's fingers and improving the smoothness of the groove wall of the groove 1103, which is conducive to reducing the angular structure of the groove wall of the groove 1103. Improve the cleaning convenience and aesthetics of the groove 1103; the aforementioned curved wall surface can be a convex curved surface, that is, the aforementioned curved wall surface is a curved surface that is convex toward the space in the groove, and the aforementioned first curved plate segment 122 is used to match the plate surface of the bottom wall of the first side groove segment 1103b can be a concave curved surface, and the aforementioned second curved plate segment 123 is used to match the plate surface of the bottom wall of the second side groove segment 1103c can also be a concave curved surface, so that each curved plate segment can adapt to the corresponding side groove segment, and can accordingly make the first curved plate segment 122 and the second curved plate segment 123 facing away from the side of the delivery port 1102 to be convex curved surface, which is beneficial to improve the aesthetics of the cover body 120 while ensuring the ease of operation of the cover body 120.

[0392] As shown in FIG. 2 to FIG. 3 , FIG. 7 and FIG. 8 , in some feasible examples, the cover portion 120 and the box body portion 110 have a consistent overall shape. For example, the side of the box body 110 on which the groove 1103 is formed may also have a main decorative surface 1104, a first side decorative surface 1105 and a second side decorative surface 1106, and the main decorative surface 1104, the first side decorative surface 1105 and the second side decorative surface 1106 are all located on the groove periphery of the groove 1103, and the main decorative surface 1104 corresponds to the main groove section 1103a, the first side decorative surface 1105 corresponds to the first side groove section 1103b, and the second side decorative surface 1106 corresponds to the second side groove section 1103c; accordingly, the position of the box body 110 corresponding to the first curved plate section 122 also includes the first side decorative surface 1105, and the position of the box body 110 corresponding to the second curved plate section 123 also includes the second side decorative surface 1106, that is, the first side decorative surface 1105 corresponds to the second side decorative surface 1106 can both be curved surfaces, and the curvature of the aforementioned first side finishing surface 1105 and the curvature of the aforementioned second side finishing surface 1106 are respectively consistent with the curvature of the aforementioned first curved plate segment 122 and the curvature of the aforementioned second curved plate segment 123; when the cover body 120 covers the aforementioned delivery port 1102, the side of the first curved plate segment 122 facing away from the delivery port 1102 is flush with the first side finishing surface 1105, the side of the second curved plate segment 123 facing away from the delivery port 1102 is flush with the second side finishing surface 1106, and the side of the main plate segment 121 facing away from the delivery port 1102 is flush with the main finishing surface 1104. Based on the above-mentioned setting, when the cover body 120 covers the aforementioned delivery port 1102, the side of the delivery unit 100 provided with the aforementioned cover body 120 can have a higher surface flatness, which is conducive to further improving the aesthetics of the delivery unit 100.

[0393] As shown in Figures 2 to 8, in some feasible examples, the edge of the groove 1103 can have multiple rounded transition structures, and accordingly, the edge of the cover body 120 can also have multiple rounded transition structures, which is conducive to further reducing the sharp corners of the groove 1103 and the cover plate, thereby helping to improve the aesthetics of the delivery unit 100 while ensuring the safety of operation.

[0394] In some feasible examples, the first arc-shaped plate segment 122 , the main body plate segment 121 and the second arc-shaped plate segment 123 are an integrated structure.

[0395] As shown in Figures 4 to 6, in some feasible examples, the aforementioned cover body 120 may also include a delivery plug 124, which is arranged on one side of the aforementioned main plate section 121 and includes a raised plug frame and a sealing ring, which is used to removably close the aforementioned delivery port 1102. When the cover body 120 covers the delivery port 1102, the delivery plug 124 is inserted into the aforementioned delivery port 1102, thereby being able to seal the delivery port 1102.

[0396] As shown in Figure 2, in some examples, the width B1 of the first arcuate plate segment 122 is smaller than the width C1 of the first side groove segment 1103b. When the cover body 120 covers the loading port 1102, an operating space 1202 is defined between the first arcuate plate segment 122 and the first side groove segment 1103b; the width of the second arcuate plate segment 123 is smaller than the width of the second side groove segment 1103c. When the cover body 120 covers the loading port 1102, an operating space 1202 is defined between the second arcuate plate segment 123 and the second side groove segment 1103c.

[0397] In this technical solution, the width B1 of the first arc-shaped plate segment 122 can be set to be smaller than the width C1 of the first side groove segment 1103b, and the width of the second arc-shaped plate segment 123 can be set to be smaller than the width of the second side groove segment 1103c, so that when the cover body 120 covers the aforementioned delivery port 1102, the first arc-shaped plate segment 122 defines an operating space 1202 in the first side groove segment 1103b, and the second arc-shaped plate segment 123 defines an operating space 1202 in the second side groove segment 1103c, so that when the cover body 120 covers the delivery port 1102, the delivery unit 100 can have two operating spaces 1202, and the two operating spaces 1202 are respectively located in the cover body 120. 0 are at two ends that are away from each other, and thus, on the one hand, the spacing distance between the two operating ends 1201 can be expanded, and thus, while being convenient for the user to apply force to different parts of the cover body 120 at the same time, the force balance of the cover body 120 during use is further improved, which is beneficial to further reduce the probability of damage to the cover body 120 and improve the convenience of opening the delivery port 1102; on the other hand, it is also convenient for the user to operate the cover body 120 through the first arc-shaped plate segment 122 and the second arc-shaped plate segment 123 when performing the opening or covering operation of the delivery port 1102, and because the contours of the first arc-shaped plate segment 122 and the second arc-shaped plate segment 123 are relatively smooth and the number of angular structures is relatively small, it is more convenient for the user to operate.

[0398] As shown in FIG5 , in some examples, the thickness of the first curved plate segment 122 decreases along the direction from the main plate segment 121 to the first curved plate segment 122 ; the thickness of the second curved plate segment 123 decreases along the direction from the main plate segment 121 to the second curved plate segment 123 .

[0399] In this technical solution, the thickness of the first curved plate segment 122 can be set to decrease along the direction from the aforementioned main plate segment 121 to the aforementioned first curved plate segment 122. Correspondingly, the thickness of the second curved plate segment 123 can be set to decrease along the direction from the aforementioned main plate segment 121 to the aforementioned second curved plate segment 123. Therefore, based on the aforementioned setting, the parts of the first curved plate segment 122 and the second curved plate segment 123 away from the main plate segment 121 can have a thinner thickness, which is beneficial to further improve the operational convenience when the user manually opens and closes the delivery port 1102, and is beneficial to reducing the weight and volume of the cover body 120, reducing the overall production cost of the cover body 120 and the delivery unit 100, and is beneficial to further reduce the use cost of the delivery unit 100.

[0400] As shown in FIG. 2 and FIG. 1 , in some examples, the dispensing unit 100 further includes: a hinge portion 130 disposed between the cover portion 120 and the box portion 110 .

[0401] In this technical solution, the aforementioned dispensing unit 100 may also include a hinge portion 130 arranged between the aforementioned cover portion 120 and the aforementioned box body portion 110, so that the cover portion 120 can be hinged to the box body portion 110 through the hinge portion 130, so as to facilitate opening or covering the aforementioned liquid injection port by rotating relative to the cover portion 120, which is beneficial for ensuring the operational convenience of the dispensing unit 100 while ensuring the reliability of the connection between the box body portion 110 and the cover portion 120.

[0402] As shown in Figures 2 to 4 and Figures 6 to 9, in some examples, the hinge portion 130 includes: a connecting member 131, which is provided on the cover body 120, and the connecting member 131 is formed with an axis hole 1311; a rotating shaft 132, which is provided on the box body 110, and the rotating shaft 132 is rotatably passed through the axis hole 1311.

[0403] In this technical solution, the aforementioned hinged portion 130 may include a connecting member 131 and a rotating shaft 132, wherein the aforementioned connecting member 131 is arranged on the aforementioned cover portion 120 and is formed with an axis hole 1311, and the aforementioned rotating shaft 132 is arranged on the aforementioned box body portion 110 and can be rotatably passed through the connecting member 131 through the aforementioned axis hole 1311, so that based on the aforementioned setting, the box body portion 110 can be pivoted relative to the cover portion 120 to realize the opening and closing of the liquid injection port, and at the same time, it can avoid the structural complexity of the hinged portion 130 being too large, which is conducive to further reducing the production difficulty and manufacturing cost of the dosing unit 100, and thereby further reducing the use cost of the dosing unit 100.

[0404] As shown in Figures 3, 4, 6 to 8, in some feasible examples, the aforementioned rotating shaft 132 and the aforementioned box body 110 can be an integrated structure, and the aforementioned connecting member 131 and the aforementioned cover body 120 can be an integrated structure, which is beneficial to improve the assembly convenience of the box body 110, the cover body 120 and the hinged part 130, and improve the structural compactness of the delivery unit 100.

[0405] As shown in Figures 3, 4, 6 to 8, in some feasible examples, the number of the aforementioned rotating shafts 132 can be two, and the aforementioned two rotating shafts 132 are coaxially and relatively arranged on the aforementioned box body 110. It can be understood that, when the aforementioned rotating shaft 132 and the aforementioned box body 110 can be an integrated structure, the aforementioned rotating shaft 132 can be a cylindrical structure protruding from the box body 110; accordingly, the number of the aforementioned through-axis holes 1311 can also be two, and the two through-axis holes 1311 are respectively located on two sides of the connecting member 131 away from each other, and each of the aforementioned rotating shafts 132 is rotatably passed through a through-axis hole 1311; thus, based on the aforementioned arrangement, it is beneficial to further improve the smoothness of the rotation of the cover body 120 relative to the box body 110, and improve the connection reliability between the cover body 120 and the box body 110.

[0406] It is understandable that the aforementioned shaft hole 1311 can be a through hole or a blind hole opened in the aforementioned connecting member 131, which can match the aforementioned rotating shaft 132.

[0407] As shown in FIG. 4 and FIG. 6 to FIG. 9 , in some examples, the connecting member 131 has a notch 1312 , and the notch 1312 is located around the through-shaft hole 1311 and communicates with the through-shaft hole 1311 .

[0408] In this technical solution, the aforementioned connecting member 131 can be formed with a notch 1312 located on the circumferential side of the through-axis hole 1311, and the aforementioned notch 1312 is connected to the aforementioned through-axis hole 1311. Therefore, based on the aforementioned setting, during the assembly process of the connecting member 131 and the rotating shaft 132, it is convenient for the rotating shaft 132 to pass through the aforementioned notch 1312 and into the through-axis hole 1311, which is conducive to further improving the assembly convenience of the hinged part 130, reducing the possibility of damage to the hinged part 130 during the assembly process, improving the production yield of the delivery unit 100, and helping to further reduce the use cost of the delivery unit 100.

[0409] As shown in Figures 3 and 7 to 9, in some examples, at least a portion of the circumferential wall of the rotating shaft 132 is an axial plane 1321, and the axial plane 1321 is parallel to the axial direction of the rotating shaft 132. The notch 1312 cooperates with the axial plane 1321 to make the rotating shaft 132 suitable for being inserted into the through-shaft hole 1311.

[0410] In this technical solution, at least part of the circumferential wall of the aforementioned rotating shaft 132 can be set as an axial plane 1321 parallel to the circumference of the rotating shaft 132, so that based on the aforementioned setting, the minimum radial dimension of the rotating shaft 132 can be reduced. During the assembly process of the connecting member 131 and the rotating shaft 132, the aforementioned rotating shaft 132 can utilize the aforementioned axial plane 1321 to cooperate with the mouth wall of the aforementioned notch 1312 to further facilitate the rotating shaft 132 to penetrate the aforementioned through-shaft hole 1311, which is beneficial to further improve the assembly convenience of the hinged part 130, reduce the possibility of damage to the hinged part 130 during the assembly process, and improve the production yield of the delivery unit 100.

[0411] As shown in Figure 9, for example, the chord length L of the aforementioned notch 1312 can be set to be smaller than the diameter of the rotating shaft 132 and approximately equal to the height H perpendicular to the axial plane 1321 in the cross section of the rotating shaft 132. In some embodiments, the aforementioned chord length L is slightly smaller than the aforementioned height H.

[0412] It is understood that, because the notch 1312 is located around and connected to the shaft hole 1311, the opening width of the notch 1312 can be represented by the chord length L of the shaft hole 1311 corresponding to the notch 1312. Accordingly, because the rotating shaft 132 is formed with the axial plane 1321, the relatively small radial dimension of the rotating shaft 132 can be represented by the height H of the cross section of the rotating shaft 132 perpendicular to the axial plane 1321. Therefore, the chord length L of the notch 1312 can be set to be approximately equal to the height H of the cross section of the rotating shaft 132 perpendicular to the axial plane 1321, preferably slightly smaller than the height H, to facilitate the rotating shaft 132 to pass through the notch 1312 into the shaft hole 1311. Furthermore, the chord length L of the notch 1312 can be set to be smaller than the diameter of the rotating shaft 132, thereby reducing the probability of the rotating shaft 132 slipping out of the shaft hole 1311 through the notch 1312 during rotation and ensuring the reliability of the hinge 130.

[0413] It can be understood that the number of the aforementioned axial planes 1321 can be greater than or equal to one. As shown in Figure 9, the number of the aforementioned axial planes 1321 can be two, and the two aforementioned axial planes 1321 are arranged parallel to each other on both sides, which is conducive to further reducing the minimum radial dimension of the rotating shaft 132 and facilitating the assembly of the rotating shaft 132.

[0414] It can be understood that when the number of axial planes 1321 is one, since the outer peripheral wall on the rotating shaft 132 opposite to the axial plane 1321 is an arc surface, the height H perpendicular to the axial plane 1321 in the cross section of the rotating shaft 132 is non-constant. Based on this situation, the chord length L of the aforementioned notch 1312 is approximately equal to the height H perpendicular to the axial plane 1321 in the cross section of the rotating shaft 132. The chord length L of the notch 1312 can be approximately equal to the maximum height H perpendicular to the axial plane 1321 in the cross section of the rotating shaft 132 to ensure the passability of the notch 1312.

[0415] As shown in Figures 20 to 22, according to the first aspect of an embodiment of the present disclosure, a dispensing system 10 is proposed, including: a dispensing unit 100, having a liquid storage chamber; a multi-way pipe fitting 600, including a first liquid inlet pipe section 601, a second liquid inlet pipe section 602 and a liquid outlet pipe section 603, and the above-mentioned first liquid inlet pipe section 601 and the above-mentioned second liquid inlet pipe section 602 are both connected to the above-mentioned liquid outlet pipe section 603; wherein the above-mentioned first liquid inlet pipe section 601 is used for water intake, the above-mentioned second liquid inlet pipe section 602 is connected to the above-mentioned dispensing unit 100, and the above-mentioned liquid outlet pipe section 603 is used to connect to the clothing processing chamber of the clothing processing equipment.

[0416] It is understood that the dispensing system 10 provided in the embodiment of the present disclosure is provided with a dispensing unit 100 and a multi-way pipe fitting 600. The dispensing unit 100 is provided with a liquid storage chamber, and the multi-way pipe fitting 600 is provided with a first liquid inlet pipe section 601, a second liquid inlet pipe section 602, and a liquid outlet pipe section 603. The first liquid inlet pipe section 601, the second liquid inlet pipe section 602, and the liquid outlet pipe section 603 are interconnected. The first liquid inlet pipe section 601 is used for water intake, and the second liquid inlet pipe section 602 is connected to the dispensing unit 100, allowing the detergent in the liquid storage chamber to flow into the second liquid inlet pipe section 602. The liquid outlet pipe section 603 can be connected to the clothing processing chamber of the clothing processing device. With this arrangement, laundry to be washed is placed into the laundry processing chamber, with washing water flowing into the first liquid inlet pipe section 601 and detergent flowing into the second liquid inlet pipe section 602. The washing water and detergent are then combined and fully mixed at the liquid outlet pipe section 603. The mixed liquid of washing water and detergent is then transported to the laundry processing chamber via the liquid outlet pipe section 603 for subsequent washing of the laundry to be washed. The washing water and detergent are fully mixed without the need for an additional mixing box, resulting in a simple and reliable structure. This allows the placement system 10 to occupy less space within the laundry processing device, enabling more rational planning of the internal space of the laundry processing device and facilitating a reduction in the overall size of the laundry processing device. This makes it more suitable for miniaturized laundry processing devices, reduces the space occupied by users, and improves the user experience.

[0417] In some examples, as shown in FIG. 22 to FIG. 25 , the angle between the first liquid inlet pipe section 601 and the second liquid inlet pipe section 602 is less than or equal to 90°.

[0418] It is understood that an angle exists between the first liquid inlet pipe section 601 and the second liquid inlet pipe section 602, and the angle is less than or equal to 90°. With this arrangement, on the one hand, a slope can be formed between the second liquid inlet pipe section 602 and the first liquid inlet pipe section 601. When the cleaning agent is transported along the second liquid inlet pipe section 602 to the liquid outlet pipe section 603, it can slide along the slope into the liquid outlet pipe section 603, ensuring smoother transportation of the cleaning agent. On the other hand, it ensures that the cleaning agent can be continuously transported and will not stay in the second liquid inlet pipe section 602. This prevents the cleaning agent from sticking to the inner wall of the second liquid inlet pipe section 602 when it is thick, causing cleaning agent residue, failing to meet the ideal cleaning amount, and making subsequent handling difficult. On the other hand, there is no need to set up an additional power source in the second liquid inlet pipe section 602 to promote the flow of cleaning agent, simplifying the structure and reducing costs.

[0419] In some examples, as shown in FIG22 , the number of the liquid storage chambers and the second liquid inlet pipe segments 602 is at least two, and each of the liquid storage chambers corresponds to one second liquid inlet pipe segment 602 .

[0420] It is understood that the number of liquid storage chambers can be set to two, and accordingly, the number of second liquid inlet pipe sections 602 is also set to two, with each liquid storage chamber corresponding to one second liquid inlet pipe section 602. This configuration allows different detergents to be stored in different liquid storage chambers to accommodate clothing that requires multiple detergents. Different detergents are then added and stored separately, mixed with the cleaning water delivered through the first liquid inlet pipe section 601 at the liquid outlet pipe section 603, and then added to the clothing treatment chamber. This allows the user to accurately determine the dosage of various detergents to ensure the best possible washing results.

[0421] For example, when washing a sweater, laundry detergent and softener are required. The laundry detergent cleans the sweater, while the softener softens it and prevents static electricity. The laundry detergent and softener are each placed in a liquid storage chamber. The laundry detergent flows from one liquid storage chamber into the corresponding second liquid inlet pipe section 602 and along this second liquid inlet pipe section 602 into the liquid outlet pipe section 603. The softener flows from another liquid storage chamber into the corresponding second liquid inlet pipe section 602 and along this second liquid inlet pipe section 602 into the liquid outlet pipe section 603. In the liquid outlet pipe section 603, the laundry detergent, softener, and washing water are thoroughly mixed and then flow into the clothing treatment chamber to act on the sweater.

[0422] For example, when only one liquid storage chamber and one second liquid inlet pipe section 602 are provided, the multi-way pipe fitting 600 can be a tee. When two liquid storage chambers and two second liquid inlet pipe sections 602 are provided, the multi-way pipe fitting 600 can be a four-way pipe fitting. For ease of illustration, as shown in FIG22 , the schematic diagrams of the supply pipeline 700 and the dispensing pipeline 500 are omitted.

[0423] In some examples, as shown in Figures 20 and 21, the above-mentioned delivery system 10 also includes: a supply pipeline 700, including a liquid inlet pipe section and a liquid injection pipe section, one end of the above-mentioned liquid inlet pipe section is connected to the above-mentioned first liquid inlet pipe section 601, and the other end is used for water intake, one end of the above-mentioned liquid injection pipe section is connected to the above-mentioned liquid outlet pipe section 603, and the other end is used to be connected to the above-mentioned clothing processing chamber; a delivery pipeline 500, one end of the above-mentioned delivery pipeline 500 is connected to the above-mentioned liquid storage chamber, and the other end is connected to the above-mentioned second liquid inlet pipe section 602.

[0424] It is understood that the dispensing system 10 is also provided with a supply pipeline 700 and a dispensing pipeline 500. The supply pipeline 700 is used to supply cleaning water to the clothing processing chamber. In some embodiments, the supply pipeline 700 is provided with a liquid inlet pipe section and a liquid injection pipe section. One end of the liquid inlet pipe section is connected to the first liquid inlet pipe section 601, and the other end can be connected to a water source. Thus, the cleaning water from the water source is transported to the first liquid inlet pipe section 601 through the liquid inlet pipe section. For example, the water source can be a faucet. One end of the liquid injection pipe section is connected to the liquid outlet pipe section 603, and the other end can be connected to the clothing processing chamber. Thus, the liquid in the liquid outlet pipe section 603 is transported into the clothing processing chamber. The dispensing pipeline 500 is used to dispense detergent into the second liquid inlet pipe section 602. In some embodiments, one end of the dispensing pipeline 500 is connected to the liquid storage chamber, and the other end is connected to the second liquid inlet pipe section 602. The user can add detergent into the liquid storage chamber, where it flows into the dispensing pipe 500 and then into the second liquid inlet pipe section 602. The provision of the supply pipe 700 and the dispensing pipe 500 makes dispensing system 10 more flexible and convenient for dispensing cleaning water and detergent to the laundry processing device. Furthermore, the dispensing system 10 can be positioned more diversely within the laundry processing device. Furthermore, the cleaning water and detergent are mixed in the liquid outlet pipe section 603 and then transported to the laundry processing chamber via the liquid injection pipe section. In the liquid injection pipe section, the cleaning water and detergent are further mixed, ensuring a more complete mixing and improving the cleaning effect.

[0425] For example, the liquid inlet pipe section can be arranged adjacent to the multi-way pipe member 600, so that a shorter liquid injection pipe section can be used to inject a mixture of detergent and washing water into the laundry processing chamber to accurately control the injection amount and avoid excessive detergent residue in the liquid injection pipe section.

[0426] Exemplarily, as shown in Figures 23 to 27, the delivery system 10 is further provided with a liquid mixing unit 800 to improve the mixing degree of the fluid medium. In some embodiments, as shown in Figures 26 and 27, the liquid mixing unit 800 is provided with a tube body 801 and a spoiler 802. Among them, the first end of the tube body 801 is connected to the liquid outlet pipe section 603, and the second end of the tube body 801 is connected to the liquid injection pipe section. At least two different fluid media can enter the tube body 801 from the first end of the tube body 801 and enter the clothing processing chamber of the clothing processing device from the second end of the tube body 801. The spoiler 802 is arranged in the tube body 801, and the fluid channel can be separated in the tube body 801 by the spoiler 802, and the circulation channel extends in a zigzag manner from the first end to the second end. This arrangement allows at least two different fluid media to flow within the tube body 801 along the fluid channel toward the second end. The fluid channel extends in a zigzag pattern, increasing the flow length of the fluid media and improving the degree of mixing of the at least two different fluid media. Furthermore, when the at least two different fluid media flow to the bend in the fluid channel, they collide with the bend, which disrupts the flow of the fluid media, changing the flow direction and reducing the flow velocity, further improving the degree of mixing of the at least two different fluid media. After being evenly mixed, the mixed fluid media are transported to the clothing treatment chamber through the liquid injection pipe section. By providing the liquid mixing unit 800, the mixed fluid media transported to the clothing treatment chamber are mixed with high uniformity and a precise mixing ratio, thereby ensuring the cleanliness of clothing treatment.

[0427] Exemplarily, the flow-disturbing portion 802 may be a fan blade, a spiral blade, or a protruding structure, so as to separate a zigzag fluid channel in the tube body 801 to ensure a cutting and flow-disturbing effect on the fluid medium.

[0428] It is understood that a power source can be provided at the first end of the tube body 801 to propel at least two different fluid media into the fluid channel and enable smooth passage through the tortuous fluid channel. This increases the pressure of the fluid media, enhances the intensity of collision with the tortuous areas of the fluid channel, and further improves the degree of mixing. For example, the power source can be a peristaltic pump.

[0429] For example, the tube body 801 can be made of a transparent material to facilitate observation of the spoiler 802 disposed inside the tube body 801 and whether there is residual fluid on the inner wall of the tube body 801, thereby facilitating subsequent maintenance operations.

[0430] For example, the fluid medium may include a variety of detergents and cleaning water. The detergents and cleaning water can be introduced from the first end of the tube body 801, mixed thoroughly through the zigzag fluid channel, and then transported to the clothing processing chamber to ensure a cleaning effect on the clothes.

[0431] As shown in Figure 27, the above-mentioned spoiler 802 includes: a first spoiler blade 8021, which is arranged in the above-mentioned tube body 801 and forms a first guide surface. The above-mentioned first guide surface is arranged obliquely relative to the axial direction of the above-mentioned tube body 801, or the above-mentioned first guide surface is a spiral surface extending along the axial direction of the above-mentioned tube body 801; wherein, a first channel section is formed between the above-mentioned first guide surface and the inner wall of the above-mentioned tube body 801, and the above-mentioned fluid channel includes the above-mentioned first channel section.

[0432] It is understood that the spoiler 802 may be provided with a first spoiler blade 8021. In some embodiments, the first spoiler blade 8021 is disposed within the tubular body 801 and forms a first guide surface within the tubular body 801. At least two different fluid media flow along the first guide surface from the first end to the second end. When the first guide surface is arranged obliquely relative to the axis of the tubular body 801, the fluid media collides with the obliquely arranged first spoiler blade 8021 during flow, slowing the flow rate of the fluid media. The power source exerts force on the fluid media, converting it into pressure on the first spoiler blade 8021. Under the action of the pressure, the at least two different fluid media are forced to mix, improving mixing uniformity. Furthermore, collision with the first spoiler blade 8021 can change the flow direction of the fluid media, causing it to flow along the oblique direction of the first guide surface, thereby extending the flow distance of the fluid media and further improving mixing uniformity.

[0433] In the case where the first guide surface is a spiral surface extending along the axial direction of the tube body 801, the fluid medium will collide with the spiral surface during the flow process, slowing down the flow speed of the fluid medium, and the power source converts the power applied to the fluid medium into pressure on the spiral surface. Under the action of pressure, at least two different fluid media are forced to mix, thereby improving the mixing uniformity, and the fluid medium can flow along the spiral direction of the spiral surface, the spiral surface cuts the fluid medium, and extends the flow distance of the fluid medium, further improving the mixing uniformity.

[0434] It can be understood that, when the first guide surface is arranged obliquely relative to the axial direction of the above-mentioned tube body 801, a plurality of first spoiler blades 8021 can be provided to improve the mixing effect of at least two different fluid media, and in some embodiments, the number of settings can be selected according to actual conditions. If too few first spoiler blades 8021 are provided, the mixing effect of at least two different fluid media will be poor. If too many first spoiler blades 8021 are provided, the flow resistance of at least two different fluid media will be large, and sufficient power is required to drive the fluid medium to flow, thereby increasing energy consumption.

[0435] For example, the spoiler 802 may be provided with a second spoiler blade 8022. In some embodiments, the second spoiler blade 8022 is disposed within the tubular body 801, and the second spoiler blade 8022 forms a second guide surface within the tubular body 801, along which at least two different fluid media flow from the second end to the second end. When the second guide surface is tilted relative to the axis of the tubular body 801, the fluid medium collides with the tilted second spoiler blade 8022 during flow, slowing down the flow rate of the fluid medium. Furthermore, the power applied by the power source to the fluid medium is converted into pressure on the second spoiler blade 8022. Under the action of the pressure, the at least two different fluid media are forced to mix, thereby improving mixing uniformity. Furthermore, collision with the second spoiler blade 8022 can change the flow direction of the fluid medium, causing it to flow along the tilted direction of the second guide surface, thereby extending the flow distance of the fluid medium and further improving mixing uniformity.

[0436] In the case where the second guide surface is a spiral surface extending along the axial direction of the tube body 801, the fluid medium will collide with the spiral surface during the flow process, slowing down the flow speed of the fluid medium, and the power source converts the power applied to the fluid medium into pressure on the spiral surface. Under the action of pressure, at least two different fluid media are forced to mix, thereby improving the mixing uniformity, and the fluid medium can flow along the spiral direction of the spiral surface, the spiral surface cuts the fluid medium, and extends the flow distance of the fluid medium, further improving the mixing uniformity.

[0437] It is understood that the second spoiler blade 8022 can be disposed on one side of the first spoiler blade 8021. The fluid medium sequentially passes through the first channel section and the second channel section. Under the combined action of the first guide surface and the second guide surface, the degree of mixing of at least two different fluid media is ensured. The first spoiler blade 8021 and the second spoiler blade 8022 differ in at least one of size, shape, and arrangement angle.

[0438] It can be understood that, when the second guide surface is arranged obliquely relative to the axial direction of the above-mentioned tube body 801, a plurality of second spoiler blades 8022 can be provided to improve the mixing effect of at least two different fluid media, and in some embodiments, the number of second spoiler blades 8022 can be selected according to actual conditions. If too few second spoiler blades 8022 are provided, the mixing effect of at least two different fluid media will be poor. If too many second spoiler blades 8022 are provided, the flow resistance of at least two different fluid media will be large, and sufficient power will be required to drive the fluid medium to flow, thereby increasing energy consumption.

[0439] Exemplarily, when the first guide surface and the second guide surface are both arranged tilted relative to the axial direction of the tube body 801, the inclination angle of the first guide surface relative to the axial direction is the same as the inclination angle of the second guide surface relative to the axial direction and is in opposite direction.

[0440] It is understood that both the first and second guide surfaces can be arranged at an angle relative to the axis of the tube body 801. Furthermore, the first and second spoiler blades 8021, 8022 have the same dimensions and the same inclination angles relative to the axis of the tube body 801, but in opposite directions. This results in the first and second guide surfaces having the same inclination angles relative to the axis of the tube body 801, but in opposite directions. With this arrangement, when the fluid medium passes through the first and second guide surfaces, it will flow in opposite directions, causing the fluids flowing in opposite directions to collide, thereby increasing the mixing of the at least two different fluid media. Furthermore, the flow of the fluid medium in opposite directions further extends the flow distance of the fluid medium, further increasing the mixing of the at least two different fluid media. Under the power provided by the power source, the fluid medium flows as a whole from the first end to the second end, ensuring that the mixed fluid medium is stably delivered to the laundry treatment chamber.

[0441] For example, the first guide surface is positioned closer to the first end than the second guide surface, and is inclined at a 45° angle relative to the axis of the tube body 801, with the inclination directed toward the second end. The second guide surface is positioned closer to the second end than the first guide surface, and is inclined at a 135° angle relative to the axis of the tube body 801, with the inclination directed toward the first end. There are four first spoiler blades 8021 and four second spoiler blades 8022, and the distances between adjacent first spoiler blades 8021 and adjacent second spoiler blades 8022 are equal.

[0442] Exemplarily, as shown in FIG27 , when both the first guide surface and the second guide surface are spiral surfaces extending along the axial direction of the tube body 801 , the rotation direction of the first guide surface is opposite to that of the second guide surface.

[0443] It is understandable that the first guide surface and the second guide surface can both be configured as spiral surfaces extending along the axis of the tube body 801, and the first spoiler blade 8021 and the second spoiler blade 8022 are of the same size and in opposite directions, so that the rotation direction of the first guide surface is opposite to that of the second guide surface. In this way, when the fluid medium passes through the first guide surface and the second guide surface, opposite spiral motion directions are generated. Fluid media with opposite spiral motion directions collide with each other. Under the influence of the spiral force, the first guide surface and the second guide surface are enhanced in terms of the ability to disturb the fluid medium and the ability to cut the fluid medium, thereby increasing the degree of mixing of at least two different fluid media. The flow of the fluid medium in the opposite spiral surface direction further extends the flow distance of the fluid medium, further increasing the degree of mixing of at least two different fluid media. Under the action of the power source providing power, the fluid medium as a whole flows from the first end to the second end, ensuring that the mixed fluid medium is stably delivered to the clothing processing chamber.

[0444] For example, the first guide surface is positioned closer to the first end than the second guide surface, has a helix angle of 45°, and is tilted toward the second end. The second guide surface is positioned closer to the second end than the first guide surface, has a helix angle of 135°, and is tilted toward the first end. The distances between adjacent first spoiler blades 8021 are equal, and the distances between adjacent second spoiler blades 8022 are equal.

[0445] Illustratively, the number of the first spoiler blades 8021 and the number of the second spoiler blades 8022 are both plural, and along the axial direction of the tube body 801 , the first spoiler blades 8021 and the second spoiler blades 8022 are alternately arranged.

[0446] It is understood that the number of first spoiler blades 8021 and second spoiler blades 8022 is multiple to increase the guide area of ​​the first guide surface and the guide area of ​​the second guide surface. The first spoiler blades 8021 and the second spoiler blades 8022 are arranged alternately. Each first spoiler blade 8021 and an adjacent second spoiler blade 8022 can form a spoiler node. When the fluid medium passes through the spoiler node, it produces a flow effect in opposite directions, and the fluid media with different flow directions can collide with each other. The fluid medium collides with both the first guide surface and the second guide surface, thereby increasing the degree of mixing of the at least two different fluid media. This arrangement also extends the flow distance of the fluid medium, further increasing the degree of mixing of the at least two different fluid media. Under the action of the power source, the fluid medium as a whole flows from the first end to the second end, ensuring that the mixed fluid medium is stably delivered to the clothing processing chamber.

[0447] Exemplarily, as shown in Figure 27 and Figure 21, when the first guide surface and the second guide surface are both spiral surfaces, along the circumference of the tube body portion 801, an angle is formed between the end of the first guide surface close to the second guide surface and the end of the second guide surface close to the first guide surface.

[0448] It is understandable that the first guide surface and the second guide surface can both be selected from spiral surfaces, and the first guide surface and the second guide surface can be alternately arranged, and the spiral angles of the first guide surface and the second guide surface are opposite. Each first spoiler blade 8021 and an adjacent second spoiler blade 8022 can form a spoiler section, and when fluid medium passes through the spoiler section, a flow effect in opposite directions can be produced, and collision can be produced between the fluid medium of different flow directions, and fluid medium and the first guide surface and the second guide surface all produce collision, thereby improving the mixing degree of at least two different fluid media. And so be arranged, extend the flow distance of fluid medium, further improve the mixing degree of at least two different fluid media. Angle is formed between an end of the first guide surface near the second guide surface and an end of the second guide surface near the first guide surface, thereby further improving the disturbance and cutting ability of fluid medium, ensuring that at least two different fluid media are evenly mixed.

[0449] Exemplarily, the angle formed between one end of the first guide surface close to the second guide surface and one end of the second guide surface close to the first guide surface is 90°, so as to achieve the maximum cutting effect and turbulence effect of the angle on the fluid medium.

[0450] Exemplarily, the spoiler 802 can be actively rotatably arranged in the tube body 801. A driving...
