[0047] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0048] The following is in conjunction with the appendix Figures 1-15 The dispensing device 100 according to an embodiment of the present invention is described.

[0049] like Figures 1-9 As shown, the dispensing device 100 according to some embodiments of the present invention includes a first dispensing hole 2145, a dispensing pump 70, and a drive button 51. The dispensing pump 70 is connected to the first dispensing hole 2145 and is used to dispense a treatment agent into the first dispensing hole 2145. The drive button 51 is tractively connected to the dispensing pump 70 and is adapted to be pressed, thereby driving the dispensing pump 70 to dispense the treatment agent into the first dispensing hole 2145. The treatment agent can be detergent, fabric softener, disinfectant, etc.

[0050] Furthermore, the dispensing device 100 also includes a valve assembly 10, which is disposed at the first dispensing hole 2145. The valve assembly 10 can open and close the first dispensing hole 2145. The drive button 51 is connected to the valve assembly 10 and is adapted to be pressed, thereby driving the valve assembly 10 to open the first dispensing hole 2145.

[0051] According to the present invention, the dispensing device 100, by driving the drive button 51 to the valve assembly 10 and the dispensing pump 70, isolates the dispensing chamber from the outside dry air after the dispensing pump 70 finishes dispensing, ensuring that the inside of the dispensing chamber is in a humid environment, preventing the residual treatment agent in the dispensing chamber from forming a film or agglomerating and affecting the normal dispensing of the next dispensing pump 70, and the valve assembly 10 closes the first dispensing hole 2145 to solve the problem of treatment agent leakage.

[0052] Meanwhile, the dispensing device of this embodiment can use the same drive structure to realize the normal operation of the dispensing pump and the opening and closing of the valve assembly, making the overall structure simpler.

[0053] like Figure 3 As shown, according to some embodiments of the present invention, the dispensing device 100 further includes a first transmission structure 54 and a second transmission structure 52. The first transmission structure 54 is drivenly connected to the valve assembly 10, and the second transmission structure 52 is drivenly connected to the dispensing pump 70. By setting the first transmission structure 54 and the second transmission structure 52, power transmission can be realized, ensuring that the valve assembly 10 can open and close normally, and ensuring that the dispensing pump 70 can dispense normally.

[0054] In some embodiments, the drive button 51 is connected to both the first transmission structure 54 and the second transmission structure 52, and the drive button 51 is adapted to be pressed to drive the first transmission structure 54 and the second transmission structure 52 to move simultaneously.

[0055] In other words, by connecting the drive button 51 with the first transmission structure 54 and the second transmission structure 52, the valve assembly 10 and the dispensing pump 70 can be linked. When the drive button 51 is pressed, the dispensing pump 70 works and the valve assembly 10 opens the first dispensing hole 2145, so that the treatment agent flows out from the first dispensing hole 2145. When the drive button 51 is released, the dispensing pump 70 stops working and the valve assembly 10 closes the first dispensing hole 2145, and the treatment agent stops flowing out. The control is convenient, the quantitative dispensing of the treatment agent is realized, and no waste of the treatment agent is caused.

[0056] like Figures 1-2 , Figures 6-9 As shown, according to some embodiments of the present invention, the valve assembly 10 includes a sealing member 11 and a movable push rod 12. The sealing member 11 is used to open and close the first dispensing hole 2145. The push rod 12 is connected to the sealing member 11 and is adapted to move under the pressing action of the drive button 51. When the push rod 12 moves, it can drive the sealing member 11 to move, thereby opening the first dispensing hole 2145.

[0057] Furthermore, the valve assembly 10 also includes a first reset member 14, which is sleeved on the push rod 12. The first reset member 14 can drive the push rod 12 to reset, thereby causing the sealing component 11 to close the first dispensing hole 2145. The valve assembly 10 can be used to control the opening and closing of the first dispensing hole 2145, which not only prevents leakage but also controls the dispensing pattern of the first dispensing hole 2145 to meet the dispensing requirements.

[0058] Specifically, in the initial state, the valve assembly 10 closes the first dispensing hole 2145; when the drive button 51 is pressed, the drive button 51 drives the valve assembly 10 to move, thereby opening the first dispensing hole 2145; when the press of the drive button 51 is released, the valve assembly 10 resets under the action of the first reset member 14, that is, the first reset member 14 drives the valve assembly 10 to move back to the initial position, thereby closing the first dispensing hole 2145.

[0059] In some embodiments, the push rod 12 includes a boss 122, which is located at one end of the push rod 12 near the first transmission structure 54. The side of the boss 122 near the first transmission structure 51 has a hemispherical structure. By setting one side of the boss 122 into a hemispherical structure, there is always a tangential contact point between the first transmission structure 54 and the push rod 12, reducing resistance and allowing the drive button 51 to smoothly push the push rod 12 downward, ensuring smooth movement.

[0060] In some specific embodiments, the outer diameter of the boss 122 is larger than the outer diameter of the first reset member 14, ensuring that the first reset member 14 abuts against the boss 122 and preventing the first reset member 14 from disengaging from the valve assembly 10.

[0061] According to some embodiments of the present invention, the sealing component 11 is detachably connected to the push rod 12, which not only facilitates the installation of the valve assembly 10 in the installation position, but also facilitates disassembly and maintenance.

[0062] like Figure 2 As shown, in some embodiments, one of the push rod 12 and the sealing component 11 has an external thread structure 121, and the other of the push rod 12 and the sealing component 11 has an internal thread structure 1111. The push rod 12 and the sealing component 11 are engaged by the external thread structure 121 and the internal thread structure 1111.

[0063] Specifically, one end of the push rod 12 is provided with an external thread structure 121, and one end of the sealing component 11 has a mating blind hole. The wall of the mating blind hole has an internal thread structure 1111. One end of the push rod 12 is inserted into the mating blind hole, and the external thread structure 121 and the internal thread structure 1111 are mated, thereby ensuring the reliability of the connection between the push rod 12 and the sealing component 11. Of course, the positions of the external thread structure 121 and the internal thread structure 1111 can also be interchanged.

[0064] like Figure 1 and Figure 2 As shown, according to some embodiments of the present invention, the sealing component 11 includes a mounting base 111, which is connected to the push rod 12. The side wall of the mounting base 111 is provided with a connecting arm 112, one end of which is connected to the side wall of the mounting base 111, and the other end of which extends in a direction away from the center line of the mounting base 111.

[0065] Furthermore, the sealing component 11 also includes a sealing element 113, which is disposed on the connecting arm 112. For example, the sealing element 113 may be disposed in the middle of the length direction of the connecting arm 112 (e.g., the direction perpendicular to the axis of the mounting base 111), or it may be disposed at the other end of the connecting arm 112 (i.e., the free end of the connecting arm 112). The sealing element 113 is used to open and close the first dispensing hole 2145.

[0066] In other words, the mounting base 111 and the seal 113 are connected via a connecting arm 112. By setting the connecting arm 112, the seal 113 can be positioned on a different axis from the push rod 12, thus allowing for a more rational arrangement of the seal 113 and reducing the axial space occupied by the valve assembly 10 on the push rod 12. Furthermore, the mounting base 111 can be equipped with multiple connecting arms 112 to connect multiple seals 113 together, which facilitates the synchronous movement of multiple seals 113.

[0067] The seal 113 can be made of silicone or plastic.

[0068] In some embodiments, the number of connecting arms 112 is equal to the number of seals 113 and they are matched one-to-one. For example, the side wall of the mounting base 111 is provided with two oppositely arranged connecting arms 112, and the free end of each connecting arm 112 is provided with a seal 113, so that two dispensing holes (such as the first dispensing hole 2145 and the second dispensing hole 2146 described below) can be controlled to open and close simultaneously using a sealing component 11.

[0069] Of course, the number of connecting arms 112 and seals 113 can be three or more, depending on the actual situation.

[0070] like Figure 2 As shown, in some embodiments, the free end of the connecting arm 112 is provided with a positioning post 1121, and the sealing member 113 is fitted onto the outside of the positioning post 1121. The positioning post 1121 not only positions the sealing member 113, but also supports the sealing member 113, preventing the sealing member 113 from deforming too much due to force and affecting the sealing of the first dispensing hole 2145.

[0071] It should be noted that the outer diameter of the positioning post 1121 can be smaller than the radial dimension of the first injection hole 2145. The sealing member 113 covers the peripheral wall of the positioning post 1121 and the end of the positioning post 1121 is exposed. Alternatively, the sealing member 113 covers both the peripheral wall and the end of the positioning post 1121, so that when the first injection hole 2145 is closed, the sealing member 113 is located between the side wall of the positioning post 1121 and the hole edge 2147 of the first injection hole 2145.

[0072] Of course, the external dimensions of the positioning post 1121 can also be greater than or equal to the dimensions of the first injection hole 2145. The sealing member 113 covers the end of the positioning post 1121, so that when the first injection hole 2145 is closed, the sealing member 113 is located between the end of the positioning post 1121 and one side of the first injection hole 2145.

[0073] In some embodiments, the seal 113 includes a sleeve 1131, a first sealing part 1132, and a second sealing part 1133. The sleeve 1131 cooperates with the connecting arm 112. For example, the sleeve 1131 can be sleeved on the outside of the positioning post 1121 of the connecting arm 112. The first sealing part 1132 and the second sealing part 1133 are disposed on the peripheral wall of the sleeve 1131 and are arranged along the axial direction of the sleeve 1131. Both the first sealing part 1132 and the second sealing part 1133 can cooperate with the hole edge 2147 of the first injection hole 2145 to achieve double sealing.

[0074] In some examples, the first sealing portion 1132 surrounds the sleeve 1131, and the first sealing portion 1132 extends radially outward along the sleeve 1131, that is, the first sealing portion 1132 extends obliquely from a direction close to the central axis of the sleeve 1131 to a direction away from the central axis of the sleeve 1131. During the process of closing the first dispensing port 2145, that is, the valve assembly 10 from... Figure 9 The indicated position moves upwards to Figure 8 At the position shown, the first sealing part 1132 is inserted into the first injection hole 2145 and can be radially interference-fitted with the hole edge 2147 of the first injection hole 2145 to achieve a seal. Since the first sealing part 1132 has a certain slope, the first sealing part 1132 can also play a guiding role.

[0075] like Figure 1 and Figure 2 As shown, in some examples, the second sealing portion 1133 includes a first sealing lip 11331 and a second sealing lip 11332 connected together. The first sealing lip 11331 and the second sealing lip 11332 respectively surround the sleeve 1131. The first sealing lip 11331 extends obliquely in the radial direction of the sleeve 1131 toward the first sealing portion 1132. The second sealing lip 11332 is located between the first sealing portion 1132 and the first sealing lip 11331. The second sealing lip 11332 extends obliquely in the radial direction of the sleeve 1131 away from the first sealing lip 11331.

[0076] In other words, the inner rings of the first sealing lip 11331 and the second sealing lip 11332 are connected and the outer rings extend away from each other, thereby forming a double-layer sealing structure with a V-shaped cross-section in the second sealing part 1133.

[0077] During the process of closing the first injection hole 2145, the valve assembly 10 inserts the first sealing part 1132 into the first injection hole 2145, which can be radially interference-fitted with the hole edge 2147 of the first injection hole 2145 to achieve sealing. Since the first sealing part 1132 has a certain slope, the first sealing part 1132 can also play a guiding role.

[0078] Furthermore, after the valve assembly 10 is moved into place, the second sealing part 1133 is in close contact with one side surface of the first dispensing hole 2145. Specifically, the first sealing lip 11331 engages with one side surface of the first dispensing hole 2145 (e.g., the plane where the lower end opening of the first dispensing hole 2145 is located) to achieve end face sealing.

[0079] Therefore, the seal 113 in this application has a dual sealing function, and the valve assembly 10 can improve the reliability of the seal during the process of closing the first injection hole 2145.

[0080] like Figure 12 As shown, according to some embodiments of the present invention, the first transmission structure 54 has a driving surface 524, which can slide with the valve assembly 10. During the pressing of the driving button 51, the driving surface 524 can drive the valve assembly 10 to move, thereby opening the first dispensing hole 2145.

[0081] Specifically, one end of the push rod 12 is connected to the sealing component 11, and the other end of the push rod 12 is slidably engaged with the driving surface 524. When the driving button 51 is pressed, the driving button 51 moves, thereby driving the dispensing pump 70 to work. At the same time, the driving surface 524 of the first transmission structure 54 can push the push rod 12 to move, and the push rod 12 drives the sealing component 11 to move, thereby opening the first dispensing hole 2145. During this process, the first reset component 14 is compressed to store elastic potential energy.

[0082] When the pressing action on the drive button 51 is released, the drive button 51 moves to the initial position. During the process of the drive button 51 moving to the initial position, the drive surface 524 of the first transmission structure 54 disengages from the push rod 12. The push rod 12 is reset under the action of the first reset member 14, thereby driving the sealing member 11 to move to close the first dispensing hole 2145.

[0083] Therefore, the drive surface 524 can transmit the movement trend of the drive button 51 to the valve assembly 10 in the direction of movement, so as to realize the drive button 51 to drive the valve assembly 100. The structure is simple and easy to install and disassemble.

[0084] In some embodiments, the drive surface 524 is inclined and the valve assembly 10 is vertical. By cooperating with the valve assembly 10, the drive surface 524 is adapted to drive the valve assembly 10 to move downward under the pressure of the drive button 51, thereby causing the sealing member 11 to open the first dispensing hole 2145. The structure is simple and easy to implement.

[0085] In some embodiments, the second transmission structure 52 includes a worm gear mechanism.

[0086] like Figure 12 and Figure 13 As shown, in some other embodiments, the second transmission structure 52 includes a gear and rack mechanism, the rack 521 of which cooperates with the drive button 51, and the gear 522 of which cooperates with the dispensing pump 70. The rack 521 extends along the moving direction of the drive button 51. For example, the rack 521 can extend horizontally or diagonally downward.

[0087] Specifically, when the drive button 51 is pressed, the rack 521 moves synchronously. Since the rack 521 meshes with the gear 522, the rack 521 can drive the gear 522 to rotate, thereby enabling the dispensing pump 70 to operate under the drive of the gear 522 and dispensing the treatment agent. When the press of the drive button 51 is released, the drive button 51 moves back to its initial position, thereby stopping the dispensing pump 70. The structure is simple.

[0088] In some embodiments, the inner side of the drive button 51 is provided with a mating groove, and the dispensing device 100 further includes a mating plate 525, which abuts against the bottom wall of the mating groove, ensuring reliable engagement. The first transmission structure 54 and the second transmission structure 52 are respectively disposed on the side of the mating plate 525 facing away from the drive button 51.

[0089] like Figure 1 , Figure 6 , Figures 11-12 As shown, according to some embodiments of the present invention, a second reset member 53 is provided between the drive button 51 and the dispensing pump 70 for driving the drive button 51 to move toward the initial position. The second reset member 53 can be used to control the drive button 51 to automatically reset, so that the valve assembly 10 closes the first dispensing hole 2145 and stops the dispensing pump 70 from running, thereby stopping the dispensing of the treatment agent and facilitating subsequent control.

[0090] When the user presses the drive button 51, the rack 521 moves synchronously, and the second reset member 53 is compressed. Since the rack 521 meshes with the gear 522, the rack 521 can drive the gear 522 to rotate, so that the dispensing pump 70 can run under the drive of the gear 522, thereby dispensing the treatment agent. At the same time, the first transmission structure 54 can drive the valve assembly 10 to move, the first reset member 14 is compressed, and the valve assembly 10 opens the first dispensing hole 2145 to realize the dispensing of the treatment agent.

[0091] When the pressing action of the drive button 51 is released, the second transmission structure 52 moves to the initial position under the action of the second reset member 53, thereby stopping the dispensing pump 70. During the process of the drive button 51 and the second transmission structure 52 moving to the initial position, the drive surface 524 disengages from the push rod 12, and the push rod 12 is reset under the action of the first reset member 14, thereby driving the sealing member 11 to move to close the first dispensing hole 2145.

[0092] The second reset member 53 is disposed between the mating plate 525 and the dispensing pump 70 to move the drive button 51 to its initial position. That is, when the user releases the pressure on the drive button 51, the second reset member 53 can drive the second transmission structure 52 to return the drive button 51 to its initial position, facilitating subsequent control.

[0093] In some embodiments, the second transmission structure 52 has a first positioning part 523, the dispensing pump 70 has a second positioning part 703, and the two ends of the second reset member 53 cooperate with the first positioning part 523 and the second positioning part 703 respectively, so that the second reset member 53 can be stably disposed between the second transmission structure 52 and the dispensing pump 70, thereby enabling the drive button 51 to achieve stable reset.

[0094] like Figures 10-11 As shown, in some examples, the first positioning part 523 / the second positioning part 703 forms a positioning hole or a positioning post to achieve a better positioning effect.

[0095] Specifically, the side of the second transmission structure 52 facing the dispensing pump 70 has a first positioning part 523, which forms a positioning hole. The side of the dispensing pump 70 facing the second transmission structure 52 has a second positioning part 703, which forms a positioning post. The second reset member 53 forms a spring, with one end of the spring inserted into the positioning hole and the other end sleeved on the positioning post to ensure the reliability of the spring installation.

[0096] like Figure 1 , Figure 2 , Figure 6As shown, in some embodiments, the dispensing device 100 includes a nozzle body 20, which also has a mounting hole 216. One end of the push rod 12 passes through the mounting hole 216 to cooperate with the sealing member 11. A gasket 13 is sleeved on the push rod 12. The gasket 13 is located outside the dispensing cavity 213. The first reset member 14 abuts against the gasket 13 so that the gasket 13 covers the gap between the hole wall of the mounting hole 216 and the push rod 12.

[0097] Therefore, by setting the shim 13, not only can the first reset member 14 be prevented from falling into the mounting hole 216 and failing to perform the reset function, but the gap between the hole wall of the mounting hole 216 and the push rod 12 can also be covered to prevent leakage.

[0098] In some embodiments, the first reset member 14 is a spring, which is sleeved on the push rod 12. One end of the spring can abut against the boss on the push rod 12, and the other end of the spring abuts against the first reset member 14, ensuring installation reliability and stability.

[0099] During installation, first insert the sealing component 11 into the dispensing cavity 213, then put the spring and gasket 13 onto the push rod 12 in sequence, then insert one end of the push rod 12 into the dispensing cavity 213 through the mounting hole 216, and connect one end of the push rod 12 to the sealing component 11.

[0100] When the push rod 12 is pressed, the push rod 12 moves downward under the action of external force, and at the same time squeezes the spring to compress the spring, and the sealing component 11 opens the first dispensing hole 2145; when the external force acting on the push rod 12 is removed, the push rod 12 returns to the initial position under the action of the spring and closes the first dispensing hole 2145 through the sealing component 11.

[0101] In an embodiment where the dispensing device 100 includes a reset member 14 and a gasket 13, one end of the reset member 14 can abut against the boss 122 and the other end can abut against the gasket 13, ensuring the installation reliability of the reset member 14 and thus ensuring that the valve assembly 10 can work normally.

[0102] According to some embodiments of the present invention, the dispensing device 100 further includes a second dispensing orifice 2146, and the valve assembly 10 is used to simultaneously open and close the first dispensing orifice 2145 and the second dispensing orifice 2146. By providing the first dispensing orifice 2145 and the second dispensing orifice 2146, the dosage of the treatment agent in a single dispensing can be increased; when one of the dispensing orifices fails, the other dispensing orifice can be used for dispensing without affecting the normal use of the dispensing device 100, thus ensuring the user's experience.

[0103] like Figure 14As shown, according to some embodiments of the present invention, the dispensing device 100 further includes a nozzle body 20, which has a dispensing cavity 213, a first dispensing hole 2145 and a second dispensing hole 2146. The first dispensing hole 2145 and the second dispensing hole 2146 are both connected to the dispensing cavity 213. The dispensing pump 70 is disposed on the nozzle body 20 and is connected to the first dispensing hole 2145 to dispense the treatment agent into the dispensing cavity 213.

[0104] In some embodiments, the nozzle body 20 has a first flow channel (not shown) and a second flow channel 2143. A first dispensing hole 2145 connects the first flow channel and the dispensing chamber 213, and a second dispensing hole 2146 connects the second flow channel 2143 and the dispensing chamber 213. The first and second flow channels 2143 can deliver the treatment agent inside each to the dispensing chamber 213. By setting the first and second flow channels 2143, the dosage of treatment agent in a single dispensing can be increased. When one flow channel fails, the other flow channel can be used for dispensing without affecting the normal use of the dispensing device 100, thus ensuring the user experience.

[0105] The nozzle body 20 has an upward-facing mounting recess 215 at its top. A dispensing pump 70 is located in the mounting recess 215 and above the first flow channel. The first flow channel is connected to the dispensing pump 70. When the dispensing pump 70 is working, it can dispense the treatment agent from the first flow channel into the dispensing chamber 213. In other words, the dispensing pump 70 can control the opening and closing of the first flow channel. When the dispensing pump 70 is pressed once, a quantitative dispensing of liquid can be achieved, thus realizing an intermittent dispensing pattern of the treatment agent. When the dispensing pump 70 is not working, it can disconnect the first flow channel, preventing the dispensing of treatment agent.

[0106] In some examples, such as Figure 14 As shown, the nozzle body 20 has a liquid passage 2142, which is connected to the first flow channel. The inlet 701 of the dispensing pump 70 is connected to the liquid passage 2142, and the outlet 702 of the dispensing pump 70 is connected to the first dispensing hole 2145. When the dispensing pump 70 is working, it can dispense the treatment agent from the liquid passage 2142 into the first dispensing hole 2145, thereby realizing the dispensing of the treatment agent.

[0107] Furthermore, the treatment agent in the second flow channel 2143 is suitable for natural release under the action of gravity. That is, there is no need to set up a separate power component to release the treatment agent in the second flow channel 2143 into the release chamber 213. Instead, the treatment agent is allowed to flow naturally into the release chamber 213 by gravity, thereby realizing the continuous liquid discharge of the treatment agent.

[0108] In some examples, the second flow channel 2143 is provided with a liquid passage hole 2144. The first flow channel is connected to the second flow channel 2143 through the liquid passage hole 2144. A portion of the treatment agent entering the second flow channel 2143 can flow along the extension direction of the second flow channel 2143 toward the second dispensing hole 2146, thereby realizing a continuous liquid discharge of the treatment agent. Another portion of the treatment agent entering the second flow channel 2143 can enter the first flow channel through the liquid passage hole 2144, thus facilitating the realization of multiple liquid discharge methods.

[0109] like Figure 14 and Figure 15 As shown, in some embodiments, the nozzle body 20 has a liquid inlet 221, which communicates with the second flow channel 2143. A storage box is provided on the top of the nozzle body 20, and the liquid outlet of the storage box communicates with the liquid inlet 221. Specifically, the treatment agent in the storage box can be discharged from the liquid outlet and then enter the second flow channel 2143 and the first flow channel through the liquid inlet 221. This allows for various liquid outlet configurations, enriching the liquid outlet options and meeting the user's needs in different scenarios.

[0110] In some embodiments, the nozzle body 20 includes a nozzle body 21 and a cover plate 22. An inlet hole 221 is provided on the cover plate 22, and a second dispensing hole 2146 is provided on the nozzle body 21. The nozzle body 21 and the cover plate 22 are connected to define a second flow channel 2143. The nozzle body 21 and the cover plate 22 can be connected by snap-fit, fasteners, welding, or bonding to ensure the reliability of the connection.

[0111] The nozzle body 21 has a flow guide groove on its upper surface. The top of the flow guide groove is open. A cover plate 22 is provided on the nozzle body 21. The cover plate 22 can close the top opening of the flow guide groove. The cover plate 22 and the flow guide groove define the second flow channel 2143. The structure is simple and easy to form.

[0112] In some examples, the cover plate 22 is provided with an annular rib 222, which protrudes from the surface of the cover plate 22 and surrounds the liquid inlet 221. The storage box is provided with a removable sealing plug, which can cooperate with the annular rib 222. Specifically, the sealing plug is located inside the storage box, and the cover plate 22 is located outside the storage box. The storage box and the cover plate 22 can be connected by the cooperation of the sealing plug and the annular rib 222, thereby fixing the storage box to the nozzle body 20. The sealing plug can be arranged concentrically with the annular rib 222, which is beneficial to the reliability and sealing of the assembly.

[0113] In some specific examples, the sealing plug can form a one-way liquid outlet channel. When the storage box is separated from the nozzle body 20, the sealing plug is in a blocked state, and the liquid in the storage box will not flow out from the location of the sealing plug. When the storage box and the nozzle body 20 are in place, the protrusion in the annular rib 222 stops the sealing plug, causing the sealing plug to switch to a conductive state, thereby ensuring smooth liquid outlet.

[0114] In some embodiments, both the valve assembly 10 and the drive button 51 are located on the nozzle body 20. The drive button 51 is connected to the valve assembly 10 and the dispensing pump 70, thereby controlling the dispensing pump 70 to operate while controlling the valve assembly 10 to open the first dispensing hole 2145 and the second dispensing hole 2146.

[0115] like Figure 3 As shown, according to some embodiments of the present invention, the top of the nozzle body 20 is provided with an outer trim component 60, which defines a mounting channel 61, and the drive button 51 is slidably engaged with the mounting channel 61. By providing the mounting channel 61 in the outer trim component 60, the mounting channel 61 can be used to position and guide the movement of the drive button 51.

[0116] Specifically, the drive button 51 is movable between a first position and a second position. The drive button 51 can be limited by the outer trim component 60 at both the first and second positions to prevent it from disengaging from the mounting channel 61. The first position is located outside the second position in the extending direction of the mounting channel 61. In its initial state, the drive button 51 is in the first position. The user presses the drive button 51, causing it to move inward along the mounting channel 61, thereby controlling the operation of the dispensing pump 70.

[0117] like Figure 15 As shown, in some embodiments, the dispensing device 100 further includes a drawer 30 that defines a dissolving chamber 31. The drawer 30 is slidably disposed within the dispensing chamber 213 between an open position and a closed position. When the drawer 30 is in the closed position, the drawer 30 is spaced apart from the bottom wall of the dispensing chamber 213 to define a liquid spray channel 33.

[0118] The treatment agent flowing out from the first dispensing hole 2145 and the second dispensing hole 2146 enters the dissolving chamber 31. Water enters the dissolving chamber 31 and mixes thoroughly with the treatment agent. Then, it enters the dispensing chamber 213 through the liquid outlet 32 ​​of the dissolving chamber 31 and is finally discharged from the multiple through holes on the bottom wall of the dispensing chamber 213 or the spray channel 33 between the drawer 30 and the bottom wall of the dispensing chamber 213, thereby improving the washing effect of the washing equipment.

[0119] In some embodiments, the two oppositely arranged sidewalls of the drawer 30 each have a guide rail 331, and the two oppositely arranged sidewalls of the dispensing cavity 213 each have a guide groove. The two guide rails 331 and the two guide grooves are slidably engaged in a one-to-one correspondence, allowing the drawer 30 to slide along the extension direction of the guide grooves, ensuring that the drawer 30 can open and close smoothly and stably. Furthermore, the guide grooves provided on the sidewalls of the dispensing cavity 213 can support the guide rails 331 of the drawer 30, so that the drawer 30 is stably installed in the dispensing cavity 213.

[0120] like Figure 15 As shown, in some embodiments, the dispensing device 100 further includes a water-dividing plate 40, which has a plurality of water outlet holes 401. The water-dividing plate 40 is located in the dispensing cavity 213 and above the drawer 30. The water-dividing plate 40 can divert the water flow before it enters the dissolving cavity 31, ensuring that the water flows into the dissolving cavity 31 evenly.

[0121] Specifically, the water distribution plate 40 and the top wall of the dispensing chamber 213 define a water-containing chamber 402, which buffers the water flow, slows down the flow rate, and allows the water to flow evenly into the dispensing chamber 213, thereby making the mixing of the water flow and the treatment agent more uniform.

[0122] like Figure 15 As shown, the water distribution plate 40 and the top wall of the dispensing cavity 213 can be connected by multiple fasteners to ensure the installation reliability of the water distribution plate 40.

[0123] The water distribution plate 40 has a clearance hole 403 for avoiding the first injection hole 2145. That is, the clearance hole 403 can avoid the valve assembly 10, which ensures that the treatment agent can directly enter the injection chamber 213 and avoids the treatment agent being injected into the water chamber 402. It also ensures that the valve assembly 10 can normally open and close the first injection hole 2145 and the second injection hole 2146.
