[0039] 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.

[0040] In the description of the embodiments of the present application, it should be noted that the terms "upper", "lower", "front", "rear", "pull-out direction", "top", "bottom", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the embodiments of the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated 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 used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0041] The present application embodiment provides a detergent dispensing device, see Figure 1 , Figure 2 , Figure 3 as well as Figure 8 , comprising a box body 1 and an on-off control component 2.

[0042] The embodiment of the present application also provides a detergent dispensing assembly, including a detergent box and a detergent dispensing device of any embodiment of the present application, wherein the detergent dispensing device is retractably disposed in the detergent box. Before washing clothes, the user pulls the detergent dispensing device out of the detergent box to dispense detergent, and after the detergent is dispensed, the detergent dispensing device is pushed into the detergent box.

[0043] In the embodiment of the present application, the detergent dispensing component is applied to a washing machine as an example for description.

[0044] See also Figure 1 , Figure 2 , Figure 5 as well as Fig.10 The box body 1 is provided with a flow channel 103, a water inlet 1d, a liquid discharge channel, a liquid storage chamber 101 for holding detergent, and a delivery chamber 102 for receiving the incoming water flow. The detergent is stored in the liquid storage chamber 101, and the capacity of the liquid storage chamber 101 can provide the amount of detergent required for multiple laundry washings, for example, 5 times, 10 times, 20 times, 50 times, 100 times, etc. In other words, the detergent delivered into the delivery chamber 102 is the detergent required for a single laundry washing.

[0045] The flow channel 103 connects the liquid storage chamber 101 and the delivery chamber 102 , that is, the detergent in the liquid storage chamber 101 can flow into the delivery chamber 102 through the flow channel 103 .

[0046] The delivery chamber 102 is connected to the water inlet 1d and the liquid discharge channel. The delivery chamber 102 is configured as follows: the delivery chamber 102 can store detergent from the liquid storage chamber 101, and the inflow water flow entering the delivery chamber 102 can be discharged from the detergent dispensing device through the liquid discharge channel. That is, before the inflow water flow enters the delivery chamber 102, the detergent entering the delivery chamber 102 from the liquid storage chamber 101 will not flow out of the delivery chamber 102, but will be stored in the delivery chamber 102. After the inflow water flow enters the delivery chamber 102 through the water inlet 1d, the inflow water flow carries the detergent and is discharged from the detergent dispensing device.

[0047] It should be noted that the detergent is in liquid form and can be a liquid with a higher viscosity, such as laundry detergent, softener, etc.; it can also be a liquid with a lower viscosity, for example, disinfectant, etc.

[0048] The on-off control member 2 selectively opens or closes the flow passage 103. That is, the on-off control member 2 can move relative to the box body 1. It is understandable that the on-off control member 2 can be movably connected to the box body 1, or can be movably connected to other structures outside the box body 1.

[0049] See also Figure 5 and Fig.10When it is not necessary to put detergent into the delivery chamber 102, the on-off control member 2 is in a state of closing the flow channel 103, that is, the on-off control member 2 is in a closed state by default, and the detergent in the liquid storage chamber 101 will not enter the delivery chamber 102. When it is necessary to release detergent into the delivery chamber 102, the on-off control member 2 switches from a closed state of closing the flow channel 103 to an open state of opening the flow channel 103, and the detergent in the liquid storage chamber 101 flows into the delivery chamber 102 through the flow channel 103. It should be noted that the user can control the time when the on-off control member 2 is in the open state according to the required amount of detergent. When the amount of detergent is sufficient for a single wash of clothes, the on-off control member 2 can be placed in a closed state of closing the flow channel 103.

[0050] The detergent dispensing device of the embodiment of the present application does not need to use a liquid pump to quantitatively extract detergent. By controlling the action of the on-off control component 2, the detergent can be quantitatively dispensed on demand. In addition, the detergent required for multiple washes can be added to the liquid storage chamber 101 at one time, and there is no need to pick up the detergent bucket and add detergent to the detergent dispensing device every time before washing clothes, thereby improving the user experience. Furthermore, since the detergent released into the dispensing chamber 102 is accumulated in the dispensing chamber 102, the user can intuitively see the amount of detergent that has been dispensed during the process of releasing the detergent or after releasing the amount of detergent required for a single wash, so that the user can control the opening time of the on-off control component 2 to achieve the effect of quantitative dispensing.

[0051] It should be noted that the detergent dispensing device needs to satisfy the requirement that the user can see the detergent in the delivery cavity 102. For example, in some embodiments, the delivery cavity 102 is exposed to the external field of view of the detergent dispensing device, that is, the user can see the detergent in the delivery cavity 102 from the outside of the detergent dispensing device during the use of the detergent dispensing device. For example, no shielding structure is provided above the delivery cavity 102, or a transparent shielding structure is provided above the delivery cavity 102. For example, in other embodiments, a movable shielding cover is provided above the delivery cavity 102, and the user can see the delivery cavity 102 by removing the shielding cover.

[0052] For example, the volume of the liquid storage chamber 101 is larger than the volume of the delivery chamber 102. The liquid storage chamber 101 can hold more detergent, reducing the frequency of the user adding detergent to the liquid storage chamber 101 from the outside, and the delivery chamber 102 only needs to facilitate water inflow and timely discharge the incoming water flow, so the volume of the delivery chamber 102 is relatively small, so as to reasonably utilize the limited space in the box body 1.

[0053] There is no limitation on the way of water entering the delivery chamber 102. For example, please refer to Figure 1 , Figure 2 , Figure 3as well as Figure 8 The top side of the delivery cavity 102 is open to form a water inlet 1d. On the one hand, it is convenient to receive the water flow from the top of the detergent dispensing device. On the other hand, the delivery cavity 102 is directly exposed to the outer surface of the detergent dispensing device, which is convenient for the user to intuitively see the detergent in the delivery cavity 102.

[0054] Specifically, the detergent box includes a shell and an upper cover, the upper cover is arranged on the top side of the upper cover, and the shell and the upper cover together define a pull-out space for accommodating the detergent dispensing device. The upper cover is provided with a water inlet channel and a water outlet, water from an external water source enters the water inlet channel, the water outlet is located above the delivery chamber 102, and the water in the water inlet channel flows downward from the water outlet and flows into the delivery chamber 102, thereby realizing water injection into the delivery chamber 102.

[0055] In this way, there is no need to set an additional water inlet pipe on the box body 1, which facilitates the simplification of the structure of the box body 1; in addition, since the detergent dispensing device needs to be pulled out frequently, the delivery cavity 102 of this embodiment can reduce the position accuracy requirements of the detergent dispensing device, making it easier for water to enter the box body 1.

[0056] Exemplarily, the housing of the detergent box is provided with a mixing tank located below the drawer space and a main water outlet connected to the mixing tank. After the detergent and water are mixed in the delivery cavity 102, they flow into the mixing tank and then enter the washing cavity of the washing device through the main water outlet.

[0057] The drainage method of the drainage channel is not limited. Exemplarily, the drainage channel is a siphon channel. When water enters the delivery chamber 102 to the siphon height, the liquid in the delivery chamber 102 is discharged based on the siphon principle. When no water enters or the incoming water flow does not reach the siphon height, the liquid in the delivery chamber 102 will not be discharged.

[0058] The formation method of the siphon channel is not limited. For example, in some embodiments, please refer to Figure 8 and Fig. 9 The detergent dispensing device includes a siphon tube 31, the water inlet end of the siphon tube 31 extends into the delivery chamber 102, the middle part of the siphon tube 31 arches up to the top of the side wall of the delivery chamber 102, and the water outlet end of the siphon tube 31 is arranged around the outside of the delivery chamber 102. The space inside the siphon tube 31 is a siphon channel, and the liquid in the delivery chamber 102 is discharged from the detergent dispensing device through the siphon tube 31.

[0059] It should be noted that, since the user needs to pull the detergent dispensing device out of the detergent box before washing, the arrangement of the siphon tube 31 should avoid interference with the detergent box. For example, see, 8 and Fig. 9 The siphon tube 31 is located at the rear end of the box body 1 along the pulling direction of the detergent dispensing device.

[0060] In some other embodiments, please refer to Figure 6 The bottom wall of the delivery cavity 102 is provided with a second liquid outlet 1b, see Figure 2 , Figure 3 ,as well as Figure 4 The detergent dispensing device includes a first siphon cap 32, which is arranged at the second liquid outlet 1b in the delivery chamber 102. When water enters the delivery chamber 102 to the siphon height, the water carrying detergent flows through the first siphon cap 32 and the second liquid outlet 1b.

[0061] The specific form of the flow channel 103 is not limited. For example, in some embodiments, a partition is provided between the liquid storage chamber 101 and the delivery chamber 102, and the flow channel can be a through hole that penetrates the partition. In other embodiments, the flow channel 103 can also be a flow channel with a certain extension length, wherein the flow channel 103 can extend in a straight line, in a curve, or in a bend, which is not limited here. It is understood that the liquid flow path in the flow channel 103 should be as short as possible to reduce the flow resistance of the detergent.

[0062] For example, see Figure 5 and Fig.10 The inlet 103a of the flow passage 103 is arranged on the bottom surface 101a of the liquid storage chamber 101, so that the position of the inlet 103a of the flow passage 103 can be minimized, and even when the amount of detergent in the liquid storage chamber 101 is small, the detergent can enter the delivery chamber 102 from the flow passage 103. The outlet 103b of the flow passage 103 is arranged on the side surface 102d of the delivery chamber 102.

[0063] For some examples, see Figure 5 and Fig.10 , the bottom surface 101a of the liquid storage chamber 101 is higher than the bottom surface 102c of the delivery chamber 102, that is, there is a certain height difference between the two. The position of the inlet 103a of the flow passage 103 is higher than the position of the outlet 103b of the flow passage 103. When the on-off control member 2 opens the flow passage 103, due to the height difference between the inlet 103a and the outlet 103b, it is convenient for the detergent to quickly flow into the delivery chamber 102.

[0064] For example, in some embodiments, please refer to Figure 2 , Figure 3 , Figure 4 as well as Fig.11The box body 1 is provided with a visual mark 15 for indicating the liquid level height in the delivery cavity 102, and the visual mark 15 is exposed to the external field of view of the detergent dispensing device, that is, the user can observe the visual mark 15 from the outside of the detergent dispensing device. In this embodiment, the visual mark 15 can provide a quantitative capacity reference, which is convenient for the user to intuitively know the current amount of detergent in the delivery cavity 102, without the user having to guess by feeling, thereby improving the user experience and the accuracy of the amount of detergent delivered.

[0065] The specific form of the visual mark 15 is not limited. For example, it can be a scale line set on the side wall of the delivery cavity 102, or a ribbon of different colors, or a pattern of different patterns, or text, etc.

[0066] For example, in some embodiments, at least a portion of the liquid storage chamber 101 is located in front of the delivery chamber 102. It is understandable that the "front" may be the front or the side front, as long as at least a portion of the liquid storage chamber 101 is closer to the delivery chamber 102. In this embodiment, after the user pulls out the detergent dispensing device from the detergent box, since at least a portion of the liquid storage chamber 101 is closer to the user, it is convenient for the user to add detergent to the liquid storage chamber 101.

[0067] It should be noted that before washing, the user will pull out the detergent dispensing device from the detergent box, but only a part of it will be pulled out, and the entire detergent dispensing device will not be completely separated from the detergent box. Therefore, even if the detergent dispensing device is pulled out, the rear end of the detergent dispensing device is still located in the detergent box, and the user cannot easily see the rear end of the detergent dispensing device. Exemplarily, in some embodiments, the dispensing chamber 102 includes a first sub-area 102a and a second sub-area 102b that are connected, the first sub-area 102a is located at the rear end of the box body 1, the second sub-area 102b extends forward from the front side of the first sub-area 102a, and the second sub-area 102a is located on one lateral side of the liquid storage chamber 101. That is, the second sub-area 102b and the liquid storage chamber 101 are arranged side by side along the left and right direction of the detergent dispensing device.

[0068] The visual mark 15 is disposed on the inner surface of the second sub-area 102b. Since the second sub-area 102b extends forward for a distance, the second sub-area 102b is more easily visible to the user after the user pulls out the detergent dispensing device. Therefore, the visual mark 15 is disposed on the side surface of the second sub-area 102b to facilitate the user to view the visual mark 15.

[0069] For example, see Figure 2 , Figure 3 , Figure 4 , Fig. 9 as well as Fig.11The inner surface of the front side of the second sub-area 102b is an inclined surface 102b' that is inclined upward, that is, the inclined surface 102b' is inclined upward, and the visual mark 15 is arranged on the inclined surface 102b'. After the user pulls out the detergent dispensing device, when the user lowers his head to look at the detergent dispensing device, the user can see the visual mark 15 more clearly and easily.

[0070] Exemplarily, the delivery chamber 102 receives the water flow through the second sub-area 102b, and the drainage channel is arranged in the first sub-area 102a.

[0071] For example, in some embodiments, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 5 as well as Fig.11 The detergent dispensing device includes a cover 5, which is disposed on the top of the box body 1 and covers the liquid storage cavity 101. The cover 5 can prevent foreign matter or dust from entering the liquid storage cavity 101, so that the detergent in the liquid storage cavity 101 remains clean.

[0072] The shape of the cover 5 is roughly adapted to the contour of the liquid storage cavity 101. It should be noted that the cover 5 does not cover the delivery cavity 102, so that the delivery cavity 102 can receive the incoming water flow.

[0073] The cover 5 can be made of a light-transmitting material, so that the user can intuitively see the remaining amount of detergent in the liquid storage chamber 101, which is convenient for the user to add detergent to the liquid storage chamber 101 in time. It is understandable that the cover 5 can also be made of an opaque material, which is not limited here.

[0074] The setting position of the on-off control member 2 is not limited, and it can be set in the liquid storage chamber 101 or in the delivery chamber 102. In the embodiment where the on-off control member 2 is set in the liquid storage chamber 101, the on-off control member 2 closes the inlet 103a of the flow passage 103. In the embodiment where the on-off control member 2 is set in the delivery chamber 102, the on-off control member 2 closes the outlet 103b of the flow passage 103.

[0075] The method of driving the on-off control member 2 to move is not limited, and can be electrically driven or manually. For example, the on-off control member 2 can be switched from the closed state to the open state under the action of an external force, that is, the on-off control member 2 is manually driven. It should be noted that the external force refers to a force outside the washing device, for example, a force applied by a user.

[0076] The direction in which the external force acts on the on-off control member 2 is not limited. For example, the on-off control member 2 is configured to be able to switch from a closed state to an open state after being pressed downward. In this embodiment, the user's force is applied downward, which is ergonomic and convenient for the user to apply force.

[0077] It is understandable that after the user manually drives the on-off control element 2 from the closed state to the open state, the user can manually reset the on-off control element 2 from the open state to the closed state, or the on-off control element 2 can be automatically reset, that is, there is no need for the user to manually reset it.

[0078] For example, in some embodiments, please refer to Figure 5 and Fig.10 The detergent dispensing device includes an elastic reset member 4, which can drive the on-off control member 2 to reset from the open state to the closed state, that is, the elastic reset member 4 drives the on-off control member 2 to automatically reset. Exemplarily, the user applies force to the on-off control member 2, so that the on-off control member 2 switches from the closed state to the open state and remains in the open state for a certain period of time. After that, the user releases the on-off control member 2, that is, the external force is removed, and the elastic reset member 4 drives the on-off control member 2 to automatically reset to the closed state.

[0079] The specific structure of the elastic reset member 4 is not limited, and it can be a cylindrical spring, a torsion spring, etc., and no limitation is made here.

[0080] The connection method between the on-off control member 2 and the box body 1 is not limited, as long as the on-off control member 2 can move relative to the box body 1 .

[0081] In some embodiments, the on-off control member 2 can reciprocate linearly relative to the box body 1. For example, the on-off control member 2 reciprocates linearly along the up and down directions of the box body 1. Exemplarily, when the user needs to release the detergent in the liquid storage chamber 101 to the delivery chamber 102, the user pulls the on-off control member 2 upward, and the on-off control member 2 moves upward, so that the on-off control member 2 is separated from the inlet 103a of the flow channel 103, and the on-off control member 2 is in an open state of opening the flow channel 103; when the flow channel 103 needs to be closed, the user can manually press the on-off control member 2, so that the on-off control member 2 moves downward to block the inlet 103a, and the on-off control member 2 is in a closed state of closing the flow channel 103. It can be understood that in an embodiment with an elastic reset member 4, when the flow channel 103 needs to be closed, the user releases the on-off control member 2, and the elastic reset member 4 automatically drives the on-off control member 2 to move downward to the position of blocking the inlet 103a.

[0082] For example, in some other embodiments, please refer to Figure 5 and Fig.10 , the on-off control member 2 is a lever mechanism. For details, please refer to Figure 7The lever mechanism includes a pressing portion 22 for pressing, a sealing portion 23 for closing the flow channel 103, and a bending rod portion 21 connecting the pressing portion 22 and the sealing portion 23. The lever mechanism is rotatably connected to the box body 1 or the cover body 5 through the bending rod portion 21, that is, the lever fulcrum is located on the bending rod portion 21, and the pressing portion 22 and the sealing portion 23 are located on the front and rear opposite sides of the lever fulcrum.

[0083] The user presses the pressing portion 22 downward, and the external force drives the lever mechanism to move along the lever fulcrum. Figure 5 or Figure 8 The sealing portion 23 is rotated counterclockwise by a certain angle. Figure 5 or Figure 8 The flow passage 103 can be opened by moving upward in the middle.

[0084] It should be noted that the inlet 103a of the flow channel 103 needs to be as close to the delivery chamber 102 as possible, and the pressing portion 22 needs to have a suitable pressing size. The lever mechanism can stagger the pressing portion 22 and the inlet 103a of the flow channel 103.

[0085] In the embodiment with the elastic reset member 4, the torque applied by the elastic reset member 4 to the lever mechanism is opposite to the torque applied by the external force to the lever mechanism. Figure 5 or Figure 8 The counterclockwise torque in the elastic reset member 4 exerts a force on the lever mechanism along Figure 5 or Figure 8 The clockwise torque in .

[0086] The elastic reset member 4 can be a torsion spring. Specifically, the torsion spring is coaxially arranged with the rotation center line of the lever mechanism. The elastic reset member 4 can also be a compression spring or a tension spring, and the position of its arrangement can be as long as it can apply a resetting torque to the lever mechanism.

[0087] Exemplarily, the pressing portion 22 is located in front of the lever fulcrum O, and the sealing portion 23 is located behind the lever fulcrum O. The rotation axis of the lever mechanism is arranged substantially horizontally along the left-right direction of the detergent dispensing device. In this embodiment, the pressing portion 22 is closer to the user than the sealing portion 23, which is convenient for the user to apply force on the one hand, and convenient for arranging the sealing portion 23 and the inlet 103a of the flow passage 103 further back on the other hand.

[0088] The specific installation method of the lever mechanism is not limited.

The pressing portion 22 is disposed at the top of the first longitudinal rod 212. The second longitudinal rod 213 extends downward from the second end of the crossbar 211. The sealing portion 23 is disposed at the bottom of the second longitudinal rod 213. The first longitudinal rod 212, the crossbar 211 and the second longitudinal rod 213 generally form a stepped structure.

[0097] The connection method between the sealing portion 23 and the second longitudinal rod 213 is not limited. For example, please refer to Figure 7 The circumferential surface of the second longitudinal rod 213 is provided with an annular groove 21a, the sealing portion 23 is sleeved on the second longitudinal rod 213 and a part of the structure of the sealing portion 23 is embedded in the annular groove 21a, so that the sealing portion 23 can be assembled on the second longitudinal rod 213 without other fasteners, the assembly method is simple, and the probability of the sealing portion 23 being separated from the second longitudinal rod 213 can be reduced.

[0098] For some examples, see Figure 5 and Fig.10 In the embodiment equipped with the elastic reset member 4, the lever mechanism includes a positioning rod 214 protruding from the upper surface or the lower surface of the cross bar 211. That is, the positioning rod 214 extends downward from the bottom side of the cross bar 211, or the positioning rod 214 extends upward from the top side of the cross bar 211. The elastic reset member 4 is a spring, and the spring is sleeved on the positioning rod 214. It should be noted that the arrangement of the positioning rod 214 and the spring needs to satisfy: in the process of pressing the pressing portion 22, the spring is compressed and stores energy.

[0099] Specifically, see Fig.10 In the embodiment where the positioning rod 214 is located at one end of the lever fulcrum O close to the sealing portion 23 , the positioning rod 214 protrudes from the upper surface of the cross bar 211 , and the positioning rod 214 extends upward from the top side of the cross bar 211 .
