Detailed Implementation

[0046] Embodiments of the present invention are described in detail below, examples of which are illustrated 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 intended to explain the present invention, and should not be construed as limiting the present invention.

[0047] Combination Figures 1 to 5 According to an embodiment of the present invention, the pumping component 11 can be used to transport fluid. The pumping component 11 includes a pump housing 111, and the pump housing 111 is provided with a first flow channel 1111 and a second flow channel 1112 that are in communication.

[0048] The pumping component 11 may further include a pump core 112, which is movably disposed on the pump housing 111 and forms a negative pressure chamber 113. The pump core 112 is configured to change the volume of the negative pressure chamber 113 by moving. The pump core 112 has a first position and a second position. In the first position, the negative pressure chamber 113 and the first flow channel 1111 are connected and the negative pressure chamber 113 and the second flow channel 1112 are disconnected. In the second position, the negative pressure chamber 113 and the second flow channel 1112 are connected and the negative pressure chamber 113 and the first flow channel 1111 are disconnected. Specifically, the pump core 112 has a first position and a second position, and the volume of the negative pressure chamber 113 changes with the change of the position of the pump core 112. For example, when the pump core 112 moves to the first position, the volume of the negative pressure chamber 113 increases, generating a negative pressure in the negative pressure chamber 113. When the pump core 112 moves to the first position, the negative pressure chamber 113 and the first flow channel 1111 are connected, so that the fluid in the first flow channel 1111 is drawn into the negative pressure chamber 113. When the pump core 112 moves to the second position, the volume of the negative pressure chamber 113 decreases, and the pressure on the fluid gradually increases. When the pump core 112 moves to the second position, the negative pressure chamber 113 and the second flow channel 1112 are connected, so that the fluid in the negative pressure chamber 113 is pushed out to the second flow channel 1112.

[0049] Combination Figure 4 and Figure 5 Taking the pump core 112 movably mounted on the pump casing 111 in the vertical direction as an example, refer to... Figure 4 When the pump core 112 moves downward, the volume of the negative pressure chamber 113 increases, and a negative pressure is generated in the negative pressure chamber 113. When the pump core 112 moves to the first position, under the action of the negative pressure, the fluid in the first flow channel 1111 can be drawn into the negative pressure chamber 113; refer to Figure 5 When the pump core 112 moves upward, the volume of the negative pressure chamber 113 decreases, and the fluid in the negative pressure chamber 113 is pushed out to the second flow channel 1112 under pressure, so that the pump core 112 can transport the fluid in the first flow channel 1111 to the second flow channel 1112 during the movement, simplifying the structure of the pumping component 11.

[0050] It should be noted that the directions indicated by "up" and "down" in the above embodiments are only for the convenience of describing the present invention and simplifying the description, and do not indicate that the pump core 112 must have a specific orientation or move in a specific orientation. Therefore, they should not be construed as limiting the present invention. The pump core 112 can also move in other directions relative to the pump housing 111.

[0051] In addition, the pump core 112 has a first position and a second position. The first position and the second position can refer to specific positions, or they can be a range of movement. When the pump core 112 moves within a certain range, this certain range is defined as the first position or the second position. For example, both the first position and the second position can have a starting position and an ending position. Taking the first position as an example, when the pump core 112 moves downward to a certain position, the negative pressure chamber 113 and the first flow channel 1111 are connected. This position is the starting position of the first position. At this time, the pump core 112 can continue to move downward, and the negative pressure chamber 113 and the first flow channel 1111 are always connected until the pump core 112 moves to the ending position. The movement range of the negative pressure chamber 113 from the starting position to the ending position during its downward movement is defined as the first position. The range of movement of the first position can be adjusted according to the fluid delivery requirements.

[0052] The pumping component 11 may further include a first coupling member 114, which is connected to the pump core 112 in a driving connection. In other words, the first coupling member 114 can drive the pump core 112 to move. For example, the first coupling member 114 may be externally connected to a driving member 23, which can drive the first coupling member 114 to move.

[0053] According to the embodiments of the present invention, the pumping component 11 is configured to cooperate with the pump core 112 and the pump housing 111. During the movement of the pump core 112, the volume of the negative pressure chamber 113 is changed to simultaneously transport the fluid. In addition, a first coupling member 114 is provided to drive the pump core 112 to move, so that the structure of the pumping component 11 is simple and the reliability is high.

[0054] The second flow channel 1112 may be equipped with a one-way valve. For example, the one-way valve may be located at the inlet, outlet, or inside the second flow channel 1112. When the pump core 112 is in the first position, the one-way valve is closed, disconnecting the second flow channel 1112 from the negative pressure chamber 113, facilitating the formation of negative pressure in the negative pressure chamber 113, and ensuring that the fluid in the first flow channel 1111 can smoothly enter the negative pressure chamber 113. When the pump core 112 is in the second position, the one-way valve may be open, facilitating the fluid in the negative pressure chamber 113 to enter the second flow channel 1112 under pressure and then be discharged.

[0055] The pumping component 11 of this embodiment can transport fluid in the first flow channel 1111 to the second flow channel 1112, and can be used in different scenarios. That is, the first flow channel 1111 and the second flow channel 1112 can be connected to different structures or components. For example, the pumping component 11 can be connected to a liquid storage device, and the liquid storage device can be connected to the first flow channel 1111. The pumping component 11 can be configured to transport fluid in the liquid storage device to the outside of the liquid storage device. As another example, the pumping component 11 can be connected to different liquid storage devices. The first flow channel 1111 can be connected to the first liquid storage device, and the second flow channel 1112 can be connected to the second liquid storage device. The pumping component 11 can transport fluid in the first liquid storage device to the second liquid storage device.

[0056] The first coupling member 114 is connected to the pump core 112 in a transmission manner. The first coupling member 114 can drive the pump core 112 to move along the axial direction of the pump core 112; or, the first coupling member 114 can drive the pump core 112 to move along the axial direction while also driving the pump core 112 to rotate along the axial direction.

[0057] Combined with the diagram Figure 2 and 3 In some embodiments of the present invention, the pump housing 111 is provided with a mounting cavity 1113 communicating with the first flow channel 1111 and the second flow channel 1112, and the pump core 112 includes a piston 1121 movably disposed in the mounting cavity 1113 along the axis. The mounting cavity 1113 can protect the pump core 112 and improve the stability of the pump core 112 during movement. In addition, the mounting cavity 1113 communicating with the first flow channel 1111 and the second flow channel 1112 facilitates the pump core 112 to change the volume of the negative pressure cavity 113 through the piston 1121 during movement, thereby realizing the delivery of fluid from the first flow channel 1111 to the second flow channel 1112, simplifying the structure of the pumping component 11.

[0058] Combination Figure 2 A first sealing element 151 may be provided between the pump core 112 and the pump housing 111. The first sealing element 151 can be fixedly connected to the pump housing 111 to improve the sealing effect of the negative pressure chamber 113 and prevent the negative pressure chamber 113 from failing to seal. For example, the first sealing element 151 may be made of rubber, which can improve the sealing effect of the negative pressure chamber 113 and reduce the wear of the pump core 112 during operation, thereby increasing its service life.

[0059] Combination Figure 3 In some embodiments of the present invention, the first flow channel 1111 extends along the axial direction, which facilitates the fluid in the first flow channel 1111 to be drawn into the negative pressure chamber 113 during the movement of the pump core 112, thereby improving the flow efficiency of the fluid.

[0060] Combination Figure 2 and Figure 6The pump core 112 also includes a rod portion 1122 connected to the piston 1121 and passing through the first flow channel 1111. The rod portion 1122 is provided with a first guide groove 1123. In the first position, the first guide groove 1123 connects the negative pressure chamber 113 and the first flow channel 1111, allowing fluid to flow into the negative pressure chamber 113 along the first flow channel 1111. When the pump core 112 moves toward the first position, the volume of the negative pressure chamber increases. Under the action of negative pressure, the fluid in the first flow channel 1111 is drawn into the negative pressure chamber 113 through the first guide groove 1123. When the pump core 112 moves toward the second position, it compresses the volume of the negative pressure chamber 113 while pushing the fluid in the negative pressure chamber 113 out to the second flow channel 1112. By providing the first guide groove 1123 in the rod portion 1122, the structure of the pumping component 11 is further simplified.

[0061] Specifically, the pump core 112 may include a connected rod 1122 and a piston 1121. The rod 1122 passes through the first flow channel 1111 and is provided with a first guide groove 1123. The piston 1121 is movably disposed in the mounting cavity 1113. During the movement of the pump core 112, the volume of the negative pressure cavity 113 can be changed by the piston 1121, and the first flow channel 1111 and the negative pressure cavity 113 can be connected through the first guide groove 1123 of the rod 1122. This facilitates the suction of fluid from the first flow channel 1111 into the negative pressure cavity 113, simplifies the structure of the pumping component 11, and improves the reliability of the pumping component 11.

[0062] The rod 1122 and piston 1121 can be integrally formed, which improves the structural strength of the pump core 112 and simplifies the manufacturing process of the pumping component 11.

[0063] Combination Figure 6 In some embodiments of the present invention, a first guide groove 1123 is disposed on the outer peripheral surface of the rod portion 1122 and extends along the axial direction, and the first guide groove 1123 penetrates the end face of the rod portion 1122 opposite to the piston 1121. The first guide groove 1123 extends along the axial direction, meaning that the first guide groove 1123 is in the same direction of movement as the pump core 112. During the movement of the pump core 112, the flow guiding efficiency of the first guide groove 1123 for the fluid can be increased. Furthermore, the first guide groove 1123 penetrating the end face of the rod portion 1122 opposite to the piston 1121 facilitates the connection of the first flow channel 1111 and the negative pressure chamber 113 when the pump core 112 moves to the first position, and disconnects the first flow channel 1111 and the negative pressure chamber 113 when moving to the second position.

[0064] Combination Figure 3 In some embodiments of the present invention, the inlet of the second flow channel 1112 is located on the circumferential surface of the mounting cavity 1113. (Combined with...) Figure 5 and Figure 6The piston 1121 is provided with a second guide groove 1124, which connects the negative pressure chamber 113 and the second flow channel 1112 at a second position. By providing the second guide groove 1124, the pump core 112 can easily guide the fluid in the negative pressure chamber 113 to the second flow channel 1112 during its movement. Specifically, when the pump core 112 moves to the first position, the fluid in the first flow channel 1111 is drawn into the negative pressure chamber 113. When the pump core 112 moves to the second position, the piston 1121 compresses the volume of the negative pressure chamber 113, increasing the pressure in the negative pressure chamber 113. At the same time, the fluid in the negative pressure chamber 113 is pushed out to the second flow channel 1112 under the pressure. By providing the second guide groove 1124 on the piston 1121, the piston 1121 can easily connect the negative pressure chamber 113 and the second flow channel 1112 while changing the volume of the negative pressure chamber when moving to the second position, simplifying the structure of the pumping component 11 and improving the fluid delivery efficiency.

[0065] Combination Figure 2 Additionally, the outlet of the second flow channel 1112 may be connected to a liquid outlet valve 14. For example, the liquid outlet valve 14 may be a duckbill valve. When the pump core 112 is in the first position, a negative pressure is generated in the negative pressure chamber 113, and the liquid outlet valve 14 may be in a closed state to prevent leakage. When the pump core 112 is in the second position, the pressure in the negative pressure chamber 113 increases, and the liquid outlet valve 14 may be in an open state so that the fluid in the second flow channel 1112 can be discharged through the liquid outlet valve 14.

[0066] Combination Figure 6 The second guide groove 1124 is disposed on the outer peripheral surface of the piston 1121 and extends along the axial direction, penetrating the end face of the piston 1121 facing the negative pressure chamber 113. The second guide groove 1124 extends along the axial direction, meaning it moves in the same direction as the pump core 112. During the movement of the pump core 112, this increases the flow guiding efficiency of the second guide groove 1124. Furthermore, the second guide groove 1124 penetrating the end face of the piston 1121 facing the negative pressure chamber 113 facilitates the connection between the second flow channel 1112 and the negative pressure chamber 113 when the pump core 112 moves to the second position.

[0067] In some embodiments of the present invention, the first seal 151 may be disposed around the rod portion 1122. When the pump core 112 disconnects the first flow channel 1111 and the negative pressure chamber 113, the sealing effect can be improved, preventing fluid in the first flow channel 1111 from entering the negative pressure chamber 113; or, the first seal 151 may be disposed around the piston 1121, which can prevent fluid leakage in the negative pressure chamber 113; or, the first seal 151 may be disposed around the rod portion 1122 and the piston 1121, that is, the outer peripheral surface of the rod portion 1122 and the outer peripheral surface of the piston 1121 may be provided with the first seal 151, thereby improving the sealing effect. In an embodiment where the first seal 151 surrounds the rod portion 1122 and the piston 1121, one first seal 151 may be provided, that is, the first seal 151 surrounds both the rod portion 1122 and the piston 1121; or, two first seals 151 may be provided, that is, one first seal 151 surrounds the rod portion 1122 and the other first seal 151 surrounds the piston 1121.

[0068] In some embodiments of the present invention, the pump core 112 is configured to be rotatable and movable in the direction about the axis of the pump core 112. That is, the pump core 112 can reciprocate along the axial direction while also rotating, thereby improving the efficiency of the pump core 112 in drawing fluid from the first flow channel 1111 into the negative pressure chamber 113 and in pushing fluid from the negative pressure chamber 113 into the second flow channel 1112 during its movement.

[0069] The rotation and axial movement of the pump core 112 can be achieved by an external drive unit 23 connected to the first coupling member 114. In other words, the drive unit 23 can drive the first coupling member 114 to move, and the first coupling member 114 can drive the pump core 112 to move. For example, the first coupling member 114 and the drive unit 23 can be equipped with a cam mechanism. The drive unit 23 can output rotational motion through a drive shaft, and the cam mechanism converts the rotational motion into rotational and linear reciprocating motion of the first coupling member 114. Alternatively, the cam mechanism can also be located in the pumping component 11.

[0070] Combination Figure 6 and Figure 7In some embodiments of the present invention, the end face of the first coupling member 114 is provided with a first cam portion 1141, and the pump housing 111 is provided with a second cam portion 1114. The second cam portion 1114 cooperates with the first cam portion 1141 to move the first coupling member 114 along the extension and retraction direction of the pump core 112 when the first coupling member 114 rotates. Specifically, when the first coupling member 114 rotates, through the cooperation of the first cam portion 1141 and the second cam portion 1114, the first coupling member 114 can move simultaneously along the axial direction of the pump core 112, thereby realizing the simultaneous rotation of the pump core 112 and extension and retraction along the axial direction, simplifying the structure of the pumping component 11. For example, the first coupling member 114 can be externally connected to the driving member 23. When the driving member 23 drives the first coupling member 114 to rotate, the first coupling member 114 can reciprocate along the axial direction simultaneously through the cooperation of the first cam portion 1141 and the second cam portion 1114. This drives the pump core 112 to reciprocate along the axial direction while rotating around the axial direction, thereby improving the fluid delivery efficiency, simplifying the structure of the pumping component 11, and improving the reliability of the pumping component 11.

[0071] Combination Figure 8 and Figure 9 The present invention also provides a liquid storage assembly 10, which includes a liquid storage container 12 and the aforementioned pumping component 11. The liquid storage container 12 has a liquid storage chamber 121, which can be used to store fluid. The pumping component 11 is connected to the liquid storage container 12, and a first flow channel 1111 communicates with the liquid storage chamber 121. The pumping component 11 can be configured to output the fluid in the liquid storage container 12.

[0072] Specifically, when the first coupling member 114 moves the pump core 112 to the first position, it can transport the fluid in the liquid storage chamber 121 to the negative pressure chamber 113 through the first flow channel 1111. When the pump core 112 moves to the second position, it can push the fluid in the negative pressure chamber 113 to the second flow channel 1112, thereby realizing the output of the fluid in the liquid storage container 12.

[0073] The liquid storage container 12 is detachably connected to the pumping component 11, which facilitates adding liquid to the liquid storage container 12 after the fluid in the liquid storage container 12 has been consumed, or replacing the liquid storage container 12 with a new one.

[0074] Combination Figure 10Furthermore, the liquid storage assembly 10 is also provided with a vent 13, which connects the liquid storage chamber 121 and the external space of the liquid storage container 12. The vent 13 can be configured to open when the air pressure in the liquid storage chamber 121 is lower than the air pressure in the external space. Specifically, when the pump core 112 moves to the first position, the air pressure in the liquid storage chamber 121 decreases. At this time, air can be introduced into the liquid storage chamber 121 through the vent 13, so that when the first flow channel 1111 connects to the negative pressure chamber 113, the fluid in the first flow channel 1111 can smoothly enter the negative pressure chamber 113.

[0075] Combined with the diagram Figure 10 and Figure 12 Optionally, the liquid storage assembly 10 may further include a cover 15, which is detachably connected to the liquid storage container 12. For example, it may be a threaded connection, which facilitates disassembly and improves the sealing effect between the cover 15 and the liquid storage container 12. The cover 15 may be fixedly connected to the pumping component 11 so that the liquid storage container 12 can be replaced after the fluid in the liquid storage container 12 is consumed, or fluid can be added to the liquid storage container 12.

[0076] Combination Figure 9 Optionally, a second seal 152 may be provided between the cover 15 and the pumping component 11 to improve the sealing effect of the liquid storage assembly 10.

[0077] Combination Figure 10 The vent 13 can be located within the cover 15. An air inlet valve 131 can be installed inside the vent 13, configured to open when the air pressure inside the liquid storage chamber 121 is lower than the external air pressure. This ensures that the fluid in the first flow channel 1111 can smoothly enter the negative pressure chamber 113 when the pump core 112 is in the first position; it also acts as a seal to prevent fluid leakage from the liquid storage chamber 121. For example, the air inlet valve 131 can be a duckbill valve. When there is no pressure difference between the liquid storage chamber 121 and the external air pressure, the air inlet valve 131 is in a sealed state due to its elasticity, preventing liquid leakage. When the air pressure inside the liquid storage chamber 121 is lower than the external air pressure, the air inlet valve 131 opens, allowing air to enter the liquid storage chamber 121, ensuring that the fluid in the liquid storage chamber 121 can smoothly enter the negative pressure chamber 113 through the first flow channel 1111.

[0078] Combination Figure 10 Furthermore, the liquid storage assembly 10 may also include an air inlet pipe 132, which extends into the liquid storage chamber 121 and connects to the vent 13. Exemplarily, the air inlet pipe 132 may be connected to a cover 15, and the cover 15 may be provided with a positioning groove for fixing the air inlet pipe 132. One end of the air inlet pipe 132 may be connected to an air inlet valve 131, and the other end may extend into the liquid storage chamber 121.

[0079] In the embodiments that include the cover 15, the cover 15 may be a module with the liquid storage container 12, and the module may be detachably connected to the pumping component 11; or, the cover 15 and the pumping component 11 may be a module, and the liquid storage container 12 may be detached from the cover 15 when liquid needs to be added or the liquid storage container 12 needs to be replaced.

[0080] Combination Figure 13 and Figure 14 The present invention also provides a liquid dispensing assembly 20, which includes a base 21. The base 21 is provided with a liquid inlet 211, a liquid outlet 212, a liquid dispensing port 213, and a third flow channel 214 that are in communication. Specifically, the liquid dispensing assembly 20 can be configured to provide a mixed solution. Exemplarily, one end of the third flow channel 214 can be connected to the liquid inlet 211, and the other end can be connected to the liquid outlet 212. The liquid dispensing port 213 can be connected to the third flow channel 214 and disposed between the liquid inlet 211 and the liquid outlet 212. Exemplarily, the liquid inlet 211 can be configured to introduce a first fluid into the third flow channel 214, and the liquid dispensing port 213 can be configured to introduce a second fluid into the third flow channel 214. The second fluid mixes with the first fluid in the third flow channel 214 to form a mixed solution, which is then discharged through the liquid outlet 212.

[0081] The liquid filling assembly 20 also includes a second coupling member 22, which is rotatably connected to the base 21. The second coupling member 22 is used to couple with the first coupling member 114 of the aforementioned pumping component 11. In other words, the liquid filling assembly 20 can be used in conjunction with the aforementioned pumping component 11.

[0082] The liquid filling assembly 20 also includes a drive member 23, which is connected to the second coupling member 22 in a transmission manner. Specifically, the drive member 23 can drive the second coupling member 22 to move, the second coupling member 22 drives the first coupling member 114 to move, and in turn drives the pump core 112 to move.

[0083] The first coupling member 114 and the second coupling member 22 are detachably connected, which facilitates the detachable connection between the liquid storage component 10 and the liquid filling component 20, thereby facilitating the replacement of the liquid storage component 10 or the addition of fluid to the liquid storage component 10, and making it easier to maintain the liquid storage component 10. In addition, the coupling of the first coupling member 114 and the second coupling member 22 can improve the reliability of the transmission structure.

[0084] Optionally, a reduction gear is provided between the driving component 23 and the second coupling component 22 to improve the transmission efficiency of the driving component 23 to the second coupling component 22. The driving component 23 and the second coupling component 22 can be arranged side-by-side, making the liquid filling assembly 20 more compact and improving space utilization.

[0085] In some embodiments of the present invention, the base 21 further includes a reset member 24, which is connected to the second coupling member 22 and the driving member 23 respectively, and elastically drives the second coupling member 22 to abut against the first coupling member 114, thereby improving the connection stability of the first coupling member 114 and the second coupling member 22, and thus enabling the second coupling member 22 to stably drive the first coupling member 114 to move.

[0086] For example, the end face of the first coupling member 114 is provided with a first cam portion 1141, and the pump housing 111 may be provided with a second cam portion 1114. The second cam portion 1114 cooperates with the first cam portion 1141 to move the first coupling member 114 along the axial direction of the pump core 112 when the first coupling member 114 rotates. Specifically, the driving member 23 can drive the second coupling member 22 to rotate, and the second coupling member 22 drives the first coupling member 114 to rotate synchronously. Through the cooperation of the first cam portion 1141 and the second cam portion 1114, the first coupling member 114 can move along the axial direction of the pump core 112 simultaneously, thereby realizing the simultaneous rotation and extension / retraction of the pump core 112, simplifying the structure of the pump core 112 assembly. By providing a reset member 24, when the first coupling member 114 moves along the axial direction of the pump core 112, the second coupling member 22 is always in a tight engagement state with the first coupling member 114, ensuring the connection stability between the first coupling member 114 and the second coupling member 22, thereby improving the working stability of the liquid storage assembly 10.

[0087] Combination Figure 11 and Figure 12 Optionally, the liquid storage assembly 10 may further include a mounting base 16 to facilitate docking between the liquid storage assembly 10 and the liquid filling assembly 20, thereby improving the stability of the liquid storage assembly 10 when installed on the liquid filling assembly 20. The liquid storage assembly 10 and the liquid filling assembly 20 can be connected by a snap-fit ​​connection, which improves the stability of the connection and facilitates disassembly. For example, one of the mounting base 16 and the base 21 may be provided with a hook, and the other may be provided with a slot.

[0088] The present invention also provides a dispensing device 100 for a water treatment system, including the aforementioned pumping component 11. Fluid can be dispensed into the water treatment system through the aforementioned pumping component 11. For example, concentrated mineralizing solution, scale inhibitor, and bactericide can be dispensed into the water through the pumping component 11.

[0089] Combination Figure 15The dispensing device 100 may include the aforementioned liquid storage assembly 10 and liquid addition assembly 20. A second coupling member 22 is drive-connected to a first coupling member 114, used to transmit the rotational motion of the second coupling member 22 to the first coupling member 114. For example, the liquid storage container 12 may store concentrated mineralized liquid, and the inlet 211 of the base 21 may be connected to pure water. Pure water flows into the third flow channel 214 from the inlet 211, and the concentrated mineralized liquid flows into the third flow channel 214 from the addition port 213. After the pure water and concentrated mineralized liquid mix in the third flow channel 214 to form water containing minerals, it is discharged from the outlet 212. By providing the aforementioned pumping component 11, the structure of the dispensing device 100 is simplified. Of course, the liquid storage container 12 may store other fluids, such as concentrated beverages. The dispensing device 100 can also be applied to chemical, food, and other fields requiring fluid dispensing.

[0090] In addition, a first coupling member 114 and a second coupling member 22 are connected for transmission, so that the first coupling member 114 and the second coupling member 22 can be detached and connected, thereby allowing the liquid storage component 10 to be disassembled from the liquid filling component 20. After the solution in the liquid storage container 12 is consumed, it is convenient to replenish the solution in the liquid storage component 10.

[0091] The dispensing device 100 may include one liquid storage component 10 or multiple liquid storage components 10. The liquid adding component 20 may be provided with a second coupling member 22 corresponding to the number of liquid storage components 10. Different fluids can be dispensed into the liquid adding component 20 by setting multiple liquid storage components 10, thereby enriching the functions of the dispensing device 100.

[0092] In some specific embodiments of the present invention, the liquid storage component 10 can be installed onto the liquid filling component 20, and the liquid storage component 10 is detachably connected to the liquid filling component 20. The liquid storage component 10 is provided with a first coupling member 114, and the liquid filling component 20 is provided with a second coupling member 22. The coupling of the first coupling member 114 and the second coupling member 22 facilitates the movement of the first coupling member 114 via the second coupling member 22, thereby driving the pump core 112. Furthermore, the provision of the first coupling member 114 and the second coupling member 22 facilitates the removal and installation of the liquid storage component 10 from the liquid filling component 20, thus facilitating the maintenance of the liquid storage component 10. The liquid storage component 10 includes a pumping component 11 and a liquid storage container 12. The pumping component 11 is detachably connected to the liquid storage container 12, facilitating the addition of liquid to the liquid storage container 12 or the replacement of the liquid storage container 12 when the solution in the liquid storage container 12 is depleted.

[0093] In addition, the driving component 23 is located on the liquid filling assembly 20 and the pumping component 11 is located on the liquid storage assembly 10, which facilitates the modular design of the liquid filling assembly 20 and the liquid storage assembly 10, and also facilitates the maintenance of the dispensing device 100.

[0094] The present invention also provides a water treatment system, comprising: a water purification module and a mineralization module, wherein the water purification module has a filter component; the mineralization module is connected to the water purification module and is used to add a mineralizing medium. Specifically, after the water purification module completes the filtration of water to form purified water, a mineralizing medium can be added to the purified water through the mineralization module to supplement the minerals required for drinking water.

[0095] The mineralization module may include the aforementioned pumping component 11; or, the mineralization module may include the aforementioned liquid storage component 10; or, the mineralization module may include the aforementioned liquid addition component 20; or the mineralization module may include the aforementioned dispensing device 100.
