[0037] The following is a further detailed description of the implementation of the present application in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present application but cannot be used to limit the scope of the present application.

[0038] In the description of the embodiments of the present application, it should be noted that the terms "upper", "lower", "top", "bottom" and the like indicate positions or location relationships based on the attached Figure 1 The orientation or position relationship shown is only for the convenience of describing the embodiments of the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the embodiments of the present application. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0039] The present application embodiment provides a detergent box 1, see Figure 1 and Figure 2 , comprising a box body 12 and a cover body 11. The cover body 11 is arranged on the top side of the box body 12, and the cover body 11 and the box body 12 together define a pull-out space for accommodating the dispenser box 3. The box body 12 is provided with a mixing tank 12a located below the pull-out space and a total water outlet 12b connected to the mixing tank 12a. Detergent and water are mixed in the mixing tank 12a, and the mixed solution enters the washing chamber of the washing device through the total water outlet 12b.

[0040] It should be noted that the specific type of detergent is not limited, for example, it can be laundry detergent, softener, disinfectant, etc.

[0041] An embodiment of the present application provides a detergent dispensing device, comprising a dispenser box 3, a liquid pump 2, and the detergent box 1 of any embodiment of the present application, the dispenser box 3 can be pulled out and arranged in the accommodating cavity, the pump inlet 2a of the liquid pump 2 is connected to the liquid suction channel 1112a, and the pump outlet 2b of the liquid pump 2 is connected to the mixing tank 12a.

[0042] See also Figure 3 and Figure 4 The cover body 11 includes a lower cover 112 and an upper cover 111. The lower cover 112 is arranged at the bottom side of the upper cover 111. The upper cover 111 and the lower cover 112 jointly define a water inlet cavity. The lower cover 112 is provided with a water outlet 112a communicating with the water inlet cavity. Figure 8 and Fig. 9 The upper cover 111 is provided with a water inlet 111e, and the water inlet cavity is connected to the water inlet 111e and the water outlet 112a.

[0043] The external water source enters the water inlet cavity and then flows into the mixing tank 12a through the water outlet 112a. That is, the detergent box 1 receives the external water source through the cover body 11, and the water in the water inlet cavity flows into the mixing tank 12a through the water outlet 112a.

[0044] See also Figures 5 to 9 The upper cover 111 includes a cover body 1111 and a liquid outlet 3b (see Figure 2 ) The docking protrusion 1112 is plug-in-fit, and the docking protrusion 1112 extends approximately along the pulling direction of the dispenser box 3. In the embodiment of the present application, the upper cover 111 is made of plastic material, and the cover body 1111 and the docking protrusion 1112 are integrally injection-molded plastic parts.

[0045] The specific material of the plastic is not limited, and illustratively includes but is not limited to: polyethylene, polypropylene, polyvinyl chloride, polystyrene, and acrylonitrile-butadiene-styrene copolymer.

[0046] The cover body 1111 is provided with a through hole 1111a penetrating the cover body 1111. Figure 6 , a liquid extraction channel 1112a is provided in the docking boss 1112, and a groove 1112b is provided on the circumferential surface of the docking boss 1112. It is understandable that the shape of the groove 1112b is not limited, and the purpose of setting the groove 1112b may be for process requirements or for sealing requirements. Exemplarily, the groove 1112b is an annular groove for installing a sealing ring. During the assembly process, the sealing ring is sleeved in the groove 1112b, and the docking boss 1112 is inserted into the liquid outlet 3b of the dispenser box 3. The sealing ring can improve the sealing matching performance between the docking boss 1112 and the liquid outlet 3b.

[0047] It should be noted that, since the dispenser box 3 needs to be pulled out relatively frequently, when the dispenser box 3 is pulled out, the docking protrusion 1112 is disengaged from the liquid outlet 3b; when the dispenser box 3 is pushed into the pulling space, the docking protrusion 1112 is inserted into the liquid outlet 3b. During the plugging and unplugging process of the docking protrusion 1112 and the liquid outlet 3b, it is necessary to ensure the sealing performance between the two and to make the friction resistance between the two relatively small, so that the user can smoothly pull out the dispenser box 3.

[0048] The through opening 1111a is located above the docking protrusion 1112. Fig. 9 In the top projection plane of the upper cover 111, the projection of the docking boss 1112 is located within the projection of the through opening 1111a, that is, the docking boss 1112 is located directly below the through opening 1111a.

[0049] It should be noted that the top view projection refers to the projection projected downward from the top of the upper cover 111. For example, Fig. 9 The view shown is the view after the top projection. The top projection plane refers to the view obtained by the top projection on the same plane.

[0050] Since the docking boss 1112 extends along the pulling direction of the dispenser box 3, the extension direction of the docking boss 1112 is perpendicular to the demolding direction of the cover body 111 after injection molding; in addition, since the circumferential surface of the docking boss 1112 has a groove 1112b, even if the docking boss 1112 adopts side parting, the side parting mold cannot be demolded along the extension direction of the docking boss 1112.

[0051] In the related art, the cover body is arranged along a direction perpendicular to Fig.10 The direction of the paper surface is the same as the direction of the mold. The butt joint boss can only be ejected along the Fig.10 The mold of the butt joint boss is demolded in the left and right directions, but cannot be demolded in the extending direction of the butt joint boss. Specifically, the mold of the butt joint boss is demolded along a plurality of slide blocks. Fig.10 The left and right directions of the butt joint are connected to form an injection cavity; during the injection molding process, the locking force of the slider is insufficient, and the casting material is easy to seep out from the parting surface between the sliders, resulting in more flash and burrs on the parting surface of the circumferential surface of the butt joint boss after demolding. The flash and burrs cannot guarantee the concentricity size of the butt joint boss and the liquid outlet 3b, thereby affecting the sealing performance between the butt joint boss and the liquid outlet 3b of the distributor box 3, and further affecting the accuracy of the liquid extraction amount of the liquid extraction pump 2.

[0052] In the embodiment of the present application, since a through hole 1111a is provided on the cover body 1111, a part of the fixed mold of the injection mold can pass through the through hole 1111a and form a cavity of the lower half of the docking boss 1112, and the movable mold of the injection mold forms a cavity of the upper half of the docking boss 1112. That is to say, the docking boss 1112 can be demolded from top to bottom, and the demolding direction is consistent with the demolding direction of the cover body 1111. The injection molding of the docking boss 1112 does not require lateral parting, and the clamping force of the movable mold and the fixed mold is used to press the upper and lower parting surfaces of the docking boss 1112, so that the casting material is not easy to seep out from the parting surface. The docking boss 1112 after cooling and molding has almost no burrs, which can effectively improve the sealing performance of the docking boss 1112 and the liquid outlet 3b of the dispenser box 3.

[0053] It should be noted that the upper and lower molds are relatively Figure 1 The upper and lower directions of the mold ejection are shown, but not specifically the mold ejection direction. For example, the upper cover of the embodiment of the present application can be molded by a horizontal injection molding machine or a vertical injection molding machine.

[0054] For example, in some embodiments, the bottom side of the cover body 1111 has an open area 111b and a water inlet area 111a for cooperating with the lower cover 112. Specifically, the lower cover 112 closes the water inlet area 111a to form a water inlet cavity. It is understandable that the lower cover 112 does not substantially cover the open area 111b, and the open area 111b faces the top surface of the distributor box 3. In this way, the distributor box 3 is convenient for plugging and unplugging with the docking boss 1112.

[0055] In some embodiments, the upper cover 111 includes a shielding member 1113, which shields the through opening 1111a. The shielding member 1113 can prevent foreign matter from falling into the detergent box 1 through the through opening 1111a from above the upper cover 111, and the shielding member 1113 can also play a role in blocking dust.

[0056] The specific shape and structure of the shielding member 1113 are not limited, as long as it can cover the through opening 1111a. For example, the shielding member 1113 can be a membrane, which can be bonded to the surface of the upper cover 111 or fixed to the surface of the upper cover 111 by ultrasonic welding or the like. For another example, the shielding member 1113 can be in the shape of a plate.

[0057] The shielding member 1113 may be disposed on the top side of the cover body 1111 or on the bottom side of the cover body 1111 , as long as it does not interfere with the movement of the dispenser box 3 .

[0058] In some embodiments, the shielding member 1113 is a light-transmitting member, that is, the shielding member 1113 is made of a light-transmitting material. In this way, during the assembly process or the maintenance process, the operator can see the matching status of the docking boss 1112 and the liquid outlet 3b of the dispenser box 3 above the upper cover 111, which has a visualization effect and is convenient for the operator to easily know the matching status of the docking boss 1112 and the liquid outlet 3b of the dispenser box 3.

[0059] For example, in some embodiments, the shielding member 1113 is detachably connected to the cover body 1111, so that the shielding member 1113 can be easily disassembled and assembled as needed. The upper cover 111 includes a flexible belt 1114, which is connected between the shielding member 1113 and the cover body 1111. In this embodiment, the shielding member 1113 and the cover body 1111 are connected by the flexible belt 1114, so that even if the shielding member 1113 is removed from the through opening 1111a, the shielding member 1113 will not be lost, which is convenient for assembly or maintenance.

[0060] The material of the flexible belt 1114 is not limited, for example, it can be steel wire, rubber band, fiber thread, hemp rope, plastic strip, etc.

[0061] In some embodiments, the flexible belt 1114 , the shielding member 1113 and the cover body 1111 are all split structures and connected together.

[0062] In other embodiments, the flexible belt 1114, the shielding member 1113 and the cover body 1111 are integrally injection molded, which can reduce the number of parts, reduce assembly processes, and save assembly time.

[0063] In order to facilitate the detachable connection between the shielding member 1113 and the cover body 1111, in some embodiments, please refer to Figure 8 , Fig. 9 , Fig.12 as well as Fig.13 The shielding member 1113 is provided with an elastic hook 11131 on one side facing the cover body 1111, see Figure 6 and Figure 8 A snap-fit ​​structure 11111 is provided on the hole wall of the through hole 1111a, and the elastic snap hook 11131 snaps into the snap-fit ​​structure 11111. When the elastic snap hook 11131 snaps into the through hole 1111a, the elastic snap hook 11131 is forced to undergo elastic deformation, and the elastic snap hook 11131 snaps onto the snap-fit ​​structure 11111 under its own elastic force, thereby realizing a detachable connection between the shielding member 1113 and the cover body 1111.

[0064] It can be understood that the clamping structure 11111 can be a groove formed on the hole wall of the through hole 1111a, or a protrusion protruding from the hole wall surface.

[0065] The number of elastic hooks 11131 is not limited, as long as the shielding member 1113 can be reliably connected to the cover body 1111. By way of example, in the embodiment of the present application, a clamping structure 11111 is provided on opposite sides of the hole wall of each through hole 1111a, and the shielding member 1113 is provided with two elastic hooks 11131 corresponding to each through hole 1111a, and each elastic hook 11131 corresponds to one clamping structure 11111.

[0066] In the embodiment of the present application, the water inlet cavity extends substantially along the pulling direction of the dispenser box 3, that is, the water inlet cavity is substantially in the shape of a long strip.

[0067] For example, see Figure 8 , Fig. 9 and Fig.10 The cover body 1111 is provided with a first channel 111c and a second channel 111d isolated from each other. One end of the first channel 111c is connected to the liquid extraction channel 1112a. Exemplarily, the first channel 111c and the liquid extraction channel 1112a are arranged in a straight line along the pulling direction of the dispenser box 3. The first channel 111c connects the pump inlet 2a of the liquid extraction pump 2 and the liquid extraction channel 1112a. Specifically, one end of the first channel 111c away from the docking boss 1112 passes through the side of the cover body 1111, one end of the second channel 111d passes through the side of the cover body 1111, and the other end of the second channel 111d extends toward the mixing tank 12a.

[0068] The liquid pump 2 is arranged at one end of the cover 11 away from the direction of extracting the dispenser box 3, and the pump inlet 2a of the liquid pump 2 is inserted into the first channel 111c. The pump outlet 2b of the liquid pump 2 extends into one end of the second channel 111d.

[0069] Under the suction action of the liquid pump 2, the detergent in the dispenser box 3 enters the liquid pump 2 through the liquid outlet 3b, the liquid extraction channel 1112a of the docking protrusion 1112, and the first channel 111c. The liquid pump 2 pumps the detergent into the second channel 111d, and then flows into the mixing tank 12a from the end of the second channel 111d. In other words, the cover body 11 is provided with the first channel 111c and the second channel 111d for each liquid pump 2.

[0070] It should be noted that a leak-proof structure is provided in the dispenser box 3. When the dispenser box 3 is separated from the docking protrusion 1112, the leak-proof structure blocks the liquid outlet 3b, and the detergent in the dispenser box 3 does not flow out from the liquid outlet 3b. When the dispenser box 3 is pushed into the draw-out space, the docking protrusion 1112 pushes open the leak-proof structure, and under the action of the liquid pump 2, the detergent in the dispenser box 3 enters the liquid extraction channel 1112a in the docking protrusion 1112 from the liquid outlet 3b.

[0071] The leak-proof structure can adopt the existing technology, which will not be described in detail here.

[0072] For some examples, see Figure 1 and Figure 2 The dispenser box 3 has a water passing area 3a that passes through the dispenser box 3 in the height direction, and the water passing area 3a is located below the water outlet 112a, so that the water from the water outlet 112a can pass through the water passing area 3a and enter the water mixing tank 12a. In this embodiment, the water flowing out of the water inlet cavity of the cover body 11 will not enter the space for containing detergent in the dispenser box 3, but directly pass through the water passing area 3a.

[0073] It should be noted that there is no limit to the number of docking protrusions 1112. The number of docking protrusions 1112 is related to the type of detergent. For example, if the dispenser box 3 stores two different detergents, the number of liquid outlets 3b is two, the number of liquid pumps 2 is two, and the number of docking protrusions 1112 is also two.

[0074] An embodiment of the present application provides a washing device, comprising a machine body and a detergent dispensing device according to any embodiment of the present application, wherein a detergent box 1 is disposed in the machine body.

[0075] The specific type of the washing device is not limited, for example, it can be a clothes processing device or a shoe washing device. The clothes processing device can be a washing machine or a washer-dryer. Among them, the structural form of the clothes processing device can be a drum type or a pulsator type.
