[0048] In order to be able to more clearly understand the above-mentioned objects, features and advantages of the present disclosure, the solutions of the present disclosure will be further described below. It should be noted that, without conflict, the embodiments of the present disclosure and the features in the embodiments can be combined with each other.

[0049] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure may be practiced in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of the present disclosure, rather than all embodiments.

[0050] As Figures 1 to 10 shown, an embodiment of the present disclosure provides a dispensing device, which includes a liquid inlet channel, a liquid storage box 20, a valve body 2, and a liquid outlet channel. Among them, the liquid inlet channel has a liquid inlet outlet 121. The liquid storage box 20 is communicated with the liquid inlet outlet 121. The valve body 2 is located at the liquid inlet outlet 121 and is used to open / close the liquid inlet outlet 121. The liquid outlet channel is communicated with the liquid storage box 20, and the valve body 2 is arranged in the liquid outlet channel and is used to open / close the liquid outlet channel.

[0051] Understandably, the liquid inlet channel is communicated with the liquid storage box 20 through the liquid inlet outlet 121. The valve body 2 is located at the liquid inlet outlet 121 and is used to open / close the liquid inlet outlet 121. Thus, when the valve body 2 opens the liquid inlet outlet 121, liquid can be added into the liquid storage box 20 through the liquid inlet channel. The liquid outlet channel is communicated with the liquid storage box 20, and the valve body 2 is arranged in the liquid outlet channel and is used to open / close the liquid outlet channel. Thus, when the valve body 2 opens the liquid outlet channel, the liquid storage box 20 can transport liquid outwards through the liquid outlet channel. When the valve body 2 closes the liquid outlet channel, the liquid storage box 20 cannot transport liquid outwards, enabling the dispensing device to achieve multiple functions.

[0052] Referring to Figure 1 and Figure 2 , the dispensing device includes a liquid inlet chamber 101. The liquid inlet chamber 101 has a bottom wall. The above-mentioned liquid inlet channel is formed in the liquid inlet chamber 101, and the liquid inlet outlet 121 is formed on the bottom wall.

[0053] Understandably, the above-mentioned valve body 2 is located in the liquid inlet chamber 101 and can open or close the liquid inlet outlet 121 through cooperation with the bottom wall.

[0054] Furthermore, the liquid outlet channel is located in the liquid inlet chamber 101. The liquid outlet channel includes a liquid outlet inlet 111 and a liquid outlet outlet 131. The liquid outlet inlet 111 is communicated with the liquid storage box 20, and the liquid outlet inlet 111 and the liquid outlet outlet 131 are arranged on the bottom wall.

[0055] In some embodiments, referring to Figure 1 and Figure 2 , the above-mentioned liquid inlet channel and the liquid outlet channel are communicated. At this time, the liquid inlet chamber 101 constitutes the above-mentioned liquid inlet channel and at least part of the liquid outlet channel, and the above-mentioned valve body 2 is located in the liquid inlet chamber 101.

[0056] Further, the valve body 2 has an open position, a closed position, and a withdrawn position within the liquid inlet chamber 101. When the valve body 2 is in the open position, the valve body 2 closes the liquid inlet 121, and the liquid outlet inlet 111 and the liquid outlet 131 are in communication; when the valve body 2 is in the closed position, the valve body 2 closes the liquid outlet inlet 111, the liquid inlet 121, and the liquid outlet 131. When the valve body 2 is in the withdrawn position, the valve body 2 can be withdrawn from the liquid inlet chamber 101 to expose the liquid inlet 121.

[0057] Understandably, the valve body 2 can be switched between the open position, the closed position, and the withdrawn position. When the valve body 2 is in the open position, the liquid outlet inlet 111 and the liquid outlet 131 can be made conductive, enabling the conveyance of liquid. At this time, the liquid inlet 121 is closed by the valve body 2. When the valve body 2 is in the closed position, the valve body 2 closes the liquid outlet inlet 111, the liquid inlet 121, and the liquid outlet 131. At this time, the liquid outlet inlet 111 and the liquid outlet 131 are in a non-conductive state, and liquid cannot be conveyed. When the valve body 2 is in the withdrawn position, it can be withdrawn from the liquid inlet chamber 101 to expose the liquid inlet 121. At this time, liquid can be introduced through the liquid inlet 121. That is to say, the valve body 2 of the dosing device can be withdrawn from the liquid inlet chamber 101 to add liquid through the liquid inlet 121, and the on-off between the liquid outlet inlet 111 and the liquid outlet 131 can also be achieved by screwing the valve body 2, realizing multiple functions. Compared with a valve structure that separately controls the on-off of the liquid outlet passage for the liquid storage box 20, it can save costs and reduce space occupation.

[0058] Specifically, the valve body 2 is rotatably disposed within the liquid inlet chamber 101 about its own axis, and a passage 221 is provided on the valve body 2. The valve body 2 rotates within the liquid inlet chamber 101 to have an open position, a closed position, and a withdrawn position. When the valve body 2 is in the open position, the passage 221 communicates the liquid outlet inlet 111 and the liquid outlet 131, enabling the liquid outlet inlet 111 and the liquid outlet 131 to be conductive.

[0059] Taking the dosing device applied to a laundry treatment device as an example, the laundry treatment device can be a washing machine, a washer-dryer, etc. The laundry treatment device has a liquid storage box 20 for holding a laundry treatment liquid. The input pipe 201 of the liquid storage box 20 is connected to the liquid inlet 121 through a pipeline, and the output pipe 202 of the liquid storage box 20 is connected to the liquid outlet inlet 111 through a pipeline, and the liquid outlet 131 can be connected to a pumping device through a pipeline. When the valve body 2 is in the open position, the liquid outlet inlet 111 and the liquid outlet 131 are conductive, and at this time, the laundry treatment liquid in the liquid storage box 20 can be pumped through the pumping device. When the valve body 2 is in the closed position, the liquid outlet inlet 111 and the liquid outlet 131 are not conductive, and at this time, the laundry treatment liquid in the liquid storage box 20 cannot be pumped through the pumping device. When the valve body 2 is in the withdrawn position and is withdrawn from the housing 1, the laundry treatment liquid can be added to the liquid storage box 20 through the liquid inlet 121.

[0060] It should be noted that the above-mentioned dosing device is not limited to being applied to laundry treatment equipment, and can also be applied to other treatment equipment that requires liquid addition and transportation, etc.

[0061] Referring to Figure 1 and Figure 2 , the dosing device further includes a housing 1. The above-mentioned housing 1 is a cylindrical structure with an opening at one end. The inner cavity of the housing 1 constitutes the above-mentioned liquid inlet chamber 101. When the valve body 2 is in the withdrawn position, the valve body 2 can be withdrawn from the liquid inlet chamber 101 through the opening.

[0062] Understandably, the housing 1 is set as a cylindrical structure with an opening at one end. After the valve body 2 is withdrawn, the liquid inlet 121 is exposed through the opening of the housing 1. In the case of being applied to laundry treatment, it is convenient to add liquid into the housing 1 and transport it to the liquid storage box through the liquid inlet 121.

[0063] It should be noted that the shape of the above-mentioned housing 1 can be cylindrical, or rectangular cylinder, etc., and is selected according to actual needs, and no specific limitation is made here.

[0064] Referring to Figure 1 and Figure 2 , in some embodiments, a dosing pipe 12 is provided on the housing 1 corresponding to the liquid inlet 121, a liquid inlet pipe 11 is provided corresponding to the liquid outlet inlet 111, and a liquid outlet pipe 13 is provided corresponding to the liquid outlet 131. By providing the dosing pipe 12, the liquid inlet pipe 11 and the liquid outlet pipe 13, it is convenient to connect with other structures through pipelines.

[0065] Referring to Figure 1 and Figure 2 , in some embodiments, the dosing device further includes a cover body 4. The cover body 4 is arranged in the liquid inlet chamber 101. The cover body 4 is provided with a limiting hole 41. The valve body 2 is rotatably arranged in the limiting hole 41 and partially extends out of the limiting hole 41.

[0066] Understandably, by providing the cover body 4, the valve body 2 can be supported and limited through the limiting hole 41, so that the valve body 2 can stably rotate around its own axis.

[0067] It should be noted that the above-mentioned cover body 4 can be connected to the housing 1 by means of adhesion, snap connection or screw connection, and no specific limitation is made here.

[0068] Referring to Figure 2 and Figure 3, in some embodiments, the valve body 2 includes a connected knob head 21 and a valve core 22, and the above-mentioned passage 221 is formed in the valve core 22. Among them, the above-mentioned valve core 22 is arranged in the limiting hole 41 of the above-mentioned cover body 4, and a part of the knob head 21 extends out of the limiting hole 41 so that the valve core 22 can be switched between an open position, a closed position and a withdrawn position by screwing the knob head 21.

[0069] That is to say, the valve body 2 is composed of a connected knob head 21 and a valve core 22, rather than integrally arranged. At this time, the connection method between the valve core 22 and the knob head 21 can be detachable or non-detachable. Among them, the detachable connection method can be snap connection, threaded connection, etc., and the non-detachable connection method can be fusion welding, soldering, etc.

[0070] Exemplarily, in a specific implementation manner, refer to Figure 2 and Figure 3 , the valve core 22 and the knob head 21 are connected by snap connection. Among them, a plurality of snap pieces 211 are arranged on the knob head 21 along its circumferential direction, a first snap protrusion is arranged on the inner side of the snap piece 211, and a card slot for the snap piece to extend into and a second snap protrusion arranged on the bottom surface of the card slot are arranged on the outer circumference of the valve core 22. When it is necessary to connect the valve core 22 and the knob head 21, the snap piece 211 is inserted into the card slot, and the first snap protrusion passes over the second snap protrusion to realize the mutual axial limitation between the valve core 22 and the knob head 21. At this time, the valve core 22 and the knob head 21 are snap-connected.

[0071] Furthermore, a first insertion rib plate extending along the axial direction of the valve core 22 is arranged on the valve core 22, and a second insertion rib plate 212 is arranged on the knob head 21. Among the first insertion rib plate and the second insertion rib plate 212, one is provided with a slot for the other to insert.

[0072] That is to say, the valve core 22 and the knob head 21 are connected by insertion through the first insertion rib plate and the second insertion rib plate 212, and the mutual circumferential limitation between the valve core 22 and the knob head 21 is realized. Thus, when the knob head 21 is rotated, the valve core 22 can rotate synchronously with the knob head 21.

[0073] It can be understood that in this implementation manner, the valve core 22 and the knob head 21 are connected by a combination of insertion connection and snap connection, ensuring that the knob head 21 can drive the valve core 22 to rotate synchronously or be withdrawn from the liquid inlet chamber 101 of the housing 1.

[0074] It should be noted that in some other embodiments, the above-mentioned valve core 22 and the knob head 21 can also be integrally arranged, that is to say, the valve core 22 and the knob head 21 are integrally processed and formed. At this time, the assembly process of the valve core 22 and the knob head 21 can be omitted, reducing the assembly difficulty.

[0075] Reference Figures 2 to 4 In some embodiments, a liquid outlet inlet 111, a liquid inlet outlet 121, and a liquid outlet outlet 131 are sequentially arranged on the bottom wall of the liquid inlet chamber 101 in the same direction. One end of the valve body 2 in the axial direction is provided with a seal 3 extending in the first direction;

[0076] When the valve body 2 is in the open position, the seal 3 closes the liquid inlet outlet 121; when the valve body 2 is in the closed position, the seal 3 closes the liquid inlet outlet 121, the liquid outlet inlet 111, and the liquid outlet outlet 131. Specifically, the seal 3 is provided on the end surface of the end of the valve core 22 away from the knob head 21.

[0077] Further, the passage 221 extends in the second direction, and the first direction intersects the second direction. It can be understood that the extending direction of the seal 3 intersects the extending direction of the passage 221, and the liquid outlet inlet 111, the liquid inlet outlet 121, and the liquid outlet outlet 131 are on a straight line. During the rotation of the valve body 2, the seal 3 can always close the liquid inlet outlet 121. When the valve body 2 rotates to the open position, the liquid outlet inlet 111 and the liquid outlet outlet 131 are communicated through the passage 221. When the valve body 2 rotates to the closed position, the seal 3 closes the liquid outlet inlet 111 and the liquid outlet outlet 131 at the same time, and at this time, the passage 221 is not on the same straight line as the connection line of the liquid outlet inlet 111 and the liquid outlet outlet 131. In this way, through the arrangement of the seal 3 and the passage 221, the liquid outlet inlet 111 and the liquid outlet outlet 131 are completely blocked.

[0078] Exemplarily, in a specific implementation manner, reference Figure 4 The first direction and the second direction are orthogonal, that is, the first direction and the second direction are perpendicular to each other.

[0079] Further, reference Figure 2 and Figure 3 The valve body 2 is provided with a plurality of insertion holes. The seal 3 includes a sealing piece 31 and a plurality of insertion protrusions 32 provided on the sealing piece 31. Each insertion protrusion 32 is inserted into an insertion hole to make the sealing piece 31 close to the end surface of the valve body 2 in the axial direction.

[0080] That is to say, the seal 3 and the valve body 2 are connected by inserting through the cooperation of the insertion holes and the insertion protrusions. Through the cooperation of the insertion holes and the insertion protrusions, the seal 3 and the valve body 2 can be tightly connected, so that the sealing piece 31 is close to the end surface of the valve body 2 in the axial direction. Thus, during the rotation of the valve body 2, the seal 3 can rotate synchronously with the valve body 2, avoiding the situation of the seal 3 curling.

[0081] It should be noted that an adhesive can also be provided between the sealing piece 31 and the valve body 2, that is, the connection stability between the sealing piece 31 and the valve body 2 is further improved by bonding.

[0082] Further, referring to Figure 4 , a seal groove 1013 for the seal 3 to enter or exit is provided on the bottom wall of the liquid inlet chamber 101. When the valve body 2 is in the open position, the seal 3 is located in the seal groove 1013.

[0083] Understandably, by providing the seal groove 1013, when the seal 3 enters the seal groove 1013, a tactile feedback will be provided to the user through the valve body 2. For example, when the seal 3 enters the seal groove 1013, the friction between the seal 3 and the bottom wall of the housing 1 gradually decreases at this time. When the seal 3 exits from the seal groove 1013, the friction between the seal 3 and the housing 1 gradually increases, so as to facilitate the user to judge whether the valve body 2 is rotated to the open position through the change of the sense of touch. Moreover, when the seal 3 enters the seal groove 1013, there is an axial displacement of the entire valve body 2, that is, the valve body 2 has an axial movement, so that the user can confirm through perception that the valve body 2 moves to the open position.

[0084] It should be noted that the setting of the depth of the seal groove 1013 will not affect the movement of the seal 3, that is, it will not cause a large blockage to the seal 3 and cause the seal 3 to curl. Among them, the depth of the seal groove 1013 can be set according to actual needs. The depth of the seal groove 1013 should not be too deep, so as not to block the seal 3 by the seal groove 1013 and cause the seal 3 to curl and affect the sealing effect. The depth of the seal groove 1013 should not be too shallow and lose the tactile feedback to the user when rotating the valve body 2.

[0085] Continuing to refer to Figure 4 , the above-mentioned liquid inlet chamber 101 is a stepped chamber, including a main body chamber 1011 and a valve body chamber 1012. The valve body 2 extends into the valve body chamber 1012, and a sealing ring 5 is provided between the valve body 2 and the cavity wall of the valve body chamber 1012. The passage 221 is relatively close to the bottom wall of the cavity of the valve body chamber 1012 with respect to the sealing ring 5. Among them, the bottom wall of the valve body chamber 1012 is provided with the above-mentioned seal groove 1013, a liquid inlet 121, a liquid outlet inlet 111, and a liquid outlet 131. Specifically, the above-mentioned valve core 22 extends into the valve body chamber 1012.

[0086] By providing the valve body chamber 1012, the valve body 2 can be limited and positioned to a certain extent, and the passage 221 is restricted below the sealing ring 5, and the space of the valve body chamber 1012 is used to realize the communication between the liquid outlet inlet 111 and the liquid outlet 131 when the valve body 2 is in the open position.

[0087] Exemplarily, in a specific implementation manner, referring to Figure 4, the liquid outlet inlet 111, the liquid inlet outlet 121, and the liquid outlet 131 are provided on the bottom wall of the cavity of the valve body chamber 1012. In this case, referring to Figure 3 , both ends of the passage 221 in its extending direction penetrate through the valve body 2 and are provided with the end face of one end of the seal 3, that is, two notches communicating with the passage 221 are formed at this time. When the valve body 2 is in the open position, the two notches are respectively opposite to the liquid outlet inlet 111 and the liquid outlet 131, so that the liquid outlet inlet 111 and the liquid outlet 131 are connected through the passage 221.

[0088] Optionally, in another specific implementation manner, the liquid outlet inlet and the liquid inlet outlet may also be provided on the groove side wall of the valve body chamber, and the liquid outlet inlet and the liquid inlet outlet are arranged oppositely. At this time, the seal only serves to close the liquid inlet outlet. When the valve body is in the open position, the liquid outlet inlet and the liquid inlet outlet are connected through the passage, and the notches on the passage can be omitted at this time. When the valve body is in the closed position, the liquid outlet inlet and the liquid inlet outlet are blocked by the outer peripheral wall of the valve body and separated.

[0089] Referring to Figure 3 and Figure 4 , in some embodiments, a limiting rib 14 is provided in the liquid inlet chamber 101. The valve body 2 has a flange 223 extending along its circumferential direction. The flange 223 is located on the side of the limiting rib 14 close to the bottom wall of the housing 1, and the flange 223 has a notch 2231 for the limiting rib 14 to pass through. When the valve body 2 is in the pulled-out position, the notch 2231 is aligned with the limiting rib 14. Specifically, the flange 223 is provided on the valve core 22.

[0090] It can be understood that through the cooperation of the flange 223 on the valve body 2 and the limiting rib 14, the flange 223 is located on the side of the limiting rib 14 close to the bottom wall. When the notch 2231 is not aligned with the limiting rib 14, the flange 223 is limited by the limiting rib 14 so that the valve body 2 cannot be pulled out from the liquid inlet chamber 101. When the notch 2231 is aligned with the limiting rib 14, the notch 2231 can avoid the limiting rib 14, so that the valve body 2 can be pulled out from the liquid inlet chamber 101 of the housing 1.

[0091] When the notch 2231 is not aligned with the limiting rib 14, the flange 223 and the limiting rib 14 can remain in contact, so that the rotation of the valve body 2 is more stable and the valve body 2 is prevented from moving axially. Alternatively, a preset gap may also be provided between the flange 223 and the limiting rib 14 to reduce the friction between the flange 223 and the limiting rib 14 and facilitate the rotation of the valve body 2.

[0092] It should be noted that the flange 223 is placed on the stepped surface formed by the body chamber 1011 and the valve body chamber 1012 to support the valve body 2 so that the valve body 2 can rotate stably.

[0093] Further, the valve body 2 is also provided with a first rib plate 224 and a second rib plate 225 extending along its axial direction. The first rib plate 224 and the second rib plate 225 are arranged at intervals in the circumferential direction of the valve body 2;

[0094] When the valve body 2 is in the closed position, the first rib plate 224 abuts against the limiting rib 14. When the valve body 2 is in the withdrawn position, the second rib plate 225 abuts against the limiting rib 14.

[0095] Understandably, by providing the first rib plate 224 and the second rib plate 225, the rotation of the valve body 2 can be limited in cooperation with the limiting rib 14. When the first rib plate 224 abuts against the limiting rib 14, it cannot continue to rotate forward due to the blockage of the limiting rib 14, which is convenient for the user to judge that the valve body 2 has reached the closed position. When the second rib plate 225 abuts against the limiting rib 14, it cannot continue to rotate forward due to the blockage of the limiting rib 14, which is convenient for the user to judge that the valve body 2 has reached the withdrawn position. At this time, the notch 2231 on the flange 223 is aligned with the limiting rib 14, and the valve body 2 can be withdrawn from the liquid inlet chamber 101 of the housing 1.

[0096] It should be noted that the first rib plate 224 and the second rib plate 225 constitute the first plug-in rib plates provided on the valve core 22. That is to say, the first rib plate 224 and the second rib plate 225 can not only cooperate with the limiting rib 14 to play a limiting role, but also cooperate with the second plug-in rib plate 212 on the knob head 21 to realize the plug-in connection between the knob head 21 and the valve core 22.

[0097] Refer to Figures 5 to 9 , the open position of the valve body 2 is located between the withdrawn position and the closed position.

[0098] Specifically, refer to Figure 5 and Figure 6 , when the valve body 2 is in the open position, the seal 3 closes the liquid inlet 121, and the liquid outlet 111 and the liquid outlet 131 are conducted through the passage 221 on the valve body 2. At this time, the limiting rib 14 limits the flange 223, and it is difficult for the valve body 2 to be withdrawn from the liquid inlet chamber 101 of the housing 1 due to the blockage of the limiting rib 14.

[0099] Refer to Figure 7 and Figure 8 , when the valve body 2 is in the closed position, the seal 3 closes the liquid inlet 121, the liquid outlet 111 and the liquid outlet 131, and the liquid outlet 111 and the liquid outlet 131 are not conducted. At this time, the first rib plate 224 abuts against the limiting rib 14, and the limiting rib 14 limits the flange 223. It is difficult for the valve body 2 to be withdrawn from the liquid inlet chamber 101 due to the blockage of the limiting rib 14.

[0100] Refer to Figure 9, the valve body 2 is in the withdrawn position, the second rib plate 225 abuts against the limiting rib 14, and the notch 2231 on the flange 223 is aligned with the limiting rib 14. At this time, the valve body 2 can be withdrawn from the liquid inlet chamber 101 to expose the liquid inlet 121.

[0101] Exemplarily, referring to Figures 5 to 9 , when the valve body 2 rotates from the open position to the closed position, the valve body 2 rotates clockwise by a first preset angle. That is to say, after the valve body 2 rotates clockwise by the first preset angle from the open position, it rotates to the closed position. When the valve body 2 rotates from the open position to the withdrawn position, the valve body 2 rotates counterclockwise by a second preset angle. That is to say, after the valve body 2 rotates counterclockwise by the second preset angle from the open position, it rotates to the withdrawn position.

[0102] Wherein, the above first preset angle and second preset angle may be the same or different. Exemplarily, referring to Figures 5 to 9 , the first preset angle and the second preset angle are the same, both being 90°. That is to say, when the valve body 2 rotates from the open position to the closed position, it needs to rotate clockwise by 90°, and when the valve body 2 rotates from the open position to the withdrawn position, it needs to rotate counterclockwise by 90°.

[0103] Optionally, it can also be that when the valve body rotates from the open position to the closed position, the valve body rotates counterclockwise by a first preset angle, and when the valve body rotates from the open position to the withdrawn position, the valve body rotates clockwise by a second preset angle.

[0104] It should be noted that multiple gears can be set between the open position and the closed position of the valve body 2 to control the communication area between the liquid outlet inlet 111 and the liquid outlet 131, so as to control the volume of the liquid in the liquid storage box extracted within a certain time.

[0105] For example, the acute angle between the first direction and the second direction is set to be as small as possible. Taking the rotation of the valve body 2 from the closed position to the open position as an example. When the valve body 2 is in the closed position, the seal 3 completely closes the liquid outlet inlet 111 and the liquid outlet 131. When the valve body 2 rotates from the closed position to the open position by a first set angle, due to the rotation of the seal 3, the liquid outlet inlet 111 and the liquid outlet 131 are partially opened, and at this time, the opened parts of the liquid outlet inlet 111 and the liquid outlet 131 are connected through the passage 221 of the valve body 2. When the valve body 2 rotates from the closed position to the open position by a second set angle, the liquid outlet inlet 111 and the liquid outlet 131 are further opened but not completely opened, and at this time, the opened parts of the liquid outlet inlet 111 and the liquid outlet 131 are connected through the passage 221 of the valve body 2. Thus, as the valve body 2 rotates, when the valve body 2 rotates to the open position, the liquid outlet inlet 111 and the liquid outlet 131 are completely opened, and at this time, the liquid outlet inlet 111 and the liquid outlet 131 are connected through the passage 221 of the valve body 2, and at this time, the flow rate of the liquid flowing out through the liquid outlet inlet 111 per unit time has a maximum value.

[0106] Thus, by controlling the rotation angle of the valve body 2, the communication area between the liquid outlet inlet 111 and the liquid outlet 131 can be controlled, thereby realizing the control of the flow rate of the liquid flowing out through the liquid outlet 131 per unit time.

[0107] Referring to Figure 10 and Figure 11 , a second aspect of the present disclosure further provides a laundry treatment device, including the dispensing device described in any one of the above embodiments.

[0108] Wherein, the liquid storage box 20 has an input pipe 201 and an output pipe 202. The input pipe 201 is connected to the liquid inlet 121 through a pipeline, the output pipe 202 is connected to the liquid outlet inlet 111 through a pipeline, and the extraction device is connected to the liquid outlet 131 through a pipeline. The liquid in the liquid storage box 20 can be laundry detergent, fabric softener, etc., and no specific limitation is made here.

[0109] Understandably, when the valve body 2 is in the open position, the liquid outlet inlet 111 and the liquid outlet 131 are conducted through the passage 221 on the valve body 2. At this time, the extraction device can extract the liquid in the liquid storage box 20. When the valve body 2 is in the closed position, the liquid outlet inlet 111 and the liquid outlet 131 are disconnected, and at this time, the extraction device cannot extract the liquid in the liquid storage box 20. When the valve body 2 is in the extraction position, the valve body 2 can be extracted from the liquid inlet chamber 101 of the housing 1 to expose the liquid inlet 121. At this time, liquid can be added to the liquid storage box 20 through the liquid inlet 121.

[0110] It should be noted that after the valve body 2 is extracted, the liquid inlet 121, the liquid outlet inlet 111, and the liquid outlet 131 are all exposed. However, the liquid outlet inlet 111 is connected to the output pipe 202 of the liquid storage box 20, and even if liquid enters, it will eventually enter the liquid storage box 20. The pipeline connected to the liquid outlet 131 extends upward, and it is difficult for liquid to enter the pipeline connected to the liquid outlet 131. Therefore, when liquid is added to the liquid inlet chamber 101 of the housing 1, more liquid will enter the liquid storage box 20 through the liquid inlet 121.

[0111] In some embodiments, referring to Figure 11 , the above laundry treatment device further includes a front support 30, and the above liquid storage box 20 is arranged on the front support 30. Wherein, the front support 30 is used to support the drum (not shown in the figure) of the laundry treatment device, and the front support 30 is located at one end of the drum with a clothing access opening. The above laundry treatment device can be a heat pump dryer or a washing machine.

[0112] In other embodiments, referring to Figure 11, the above-mentioned laundry treatment device further includes a front support 30, and the above-mentioned liquid inlet chamber 101 is arranged on the front support 30. Among them, the front support 30 is used to support the drum of the laundry treatment device (not shown in the figure), and the front support 30 is located at one end of the drum where the laundry loading and unloading opening is provided. The above-mentioned laundry treatment device can be a heat pump dryer or a washing machine.

[0113] In this case, the upper liquid storage box 20 can also be arranged on the front support 30 to shorten the distance between the liquid storage box 20 and the liquid inlet chamber 101, so as to facilitate the layout of the pipeline.

[0114] It should be noted that the dosing device in this embodiment can be applied to large-piece automatic washing machine-type laundry treatment devices, and can also be applied to small-piece laundry treatment devices such as underwear washing machines. The type and model of the laundry treatment device to which the dosing device is applied are not limited.
