[0017] In some embodiments of the liquid dispensing device, the rear cover mechanism is provided with a liquid inlet channel, which is configured to introduce liquid into the liquid dispensing device;

[0018] The liquid dispensing device further includes a liquid dispensing component and a liquid dispensing mechanism.

[0031] The aforementioned liquid dispensing device, when installed in a liquid dispensing system, not only provides excellent cleaning performance but also prevents scale buildup at the dispensing holes and enables immediate shut-off of the liquid dispensing. Specifically, the housing mechanism and descaling components are positioned close to each other, allowing multiple descaling elements to adhere to multiple dispensing sections, thus disconnecting the dispensing holes from the dispensing chamber. This accelerates liquid discharge from the dispensing holes as the descaling elements approach the dispensing sections, flushing the holes, preventing scale formation, and easily removing existing scale and impurities. The adhesion between the descaling elements and the dispensing sections causes vibration or deformation, loosening existing scale and facilitating its removal by the liquid. Furthermore, the descaling elements can seal the dispensing holes, preventing liquid from escaping and enabling immediate shut-off of the liquid dispensing. The shell mechanism and the descaling components are spaced far apart to separate multiple descaling elements from multiple liquid outlets, thus connecting the liquid outlet holes to the liquid outlet chambers. Separation of the descaling elements from the liquid outlets allows air to enter the liquid outlet holes, flushing away existing scale and impurities, facilitating their discharge with the liquid. Furthermore, the air entering the liquid outlet holes creates suction on the liquid outlets, causing vibration or deformation, which also loosens the scale formed in the liquid outlet holes, making it easier to be flushed away by the liquid.

[0032] Other features and advantages of this disclosure will be set forth in the following description and will be apparent in part from the description or may be learned by practicing the disclosure.

[0058] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in this disclosure can be arbitrarily combined with each other.

[0059] This disclosure provides a liquid dispensing device and system. The system can be installed in various environments such as companies, schools, homes, and factories to clean items and body parts, thereby improving people's quality of life and health. The system includes a liquid dispensing device. There can be one or more dispensing devices. The device can be, but is not limited to, a faucet, shower head, or spray gun. Furthermore, the system may include other dispensing devices such as overhead sprays and / or spray booms, enabling it to meet diverse bathing needs.

[0060] To facilitate the description of the technical solution disclosed herein, the following explanation uses a shower head as an example of a liquid dispensing device.

[0061] Please combine them together Figures 1 to 3 , Figure 7 , Figure 8 , Figure 10 , Figure 11 , Figure 13 , Figure 16 , Figure 17 , Figures 19 to 22 The liquid dispensing device provided in the embodiments of this disclosure will now be described. The liquid dispensing device includes a rear cover mechanism 10, a front shell mechanism 20, and a descaling component 30.

[0062] A faceplate mechanism 20 is disposed on the rear cover mechanism 10. The faceplate mechanism 20 is provided with a liquid outlet chamber 100, which is configured to provide space for liquid to enter. The faceplate mechanism 20 is provided with multiple liquid outlet sections 40, each of which is provided with at least one liquid outlet hole 200, which communicates with the liquid outlet chamber 100. A descaling assembly 30 is installed in the liquid outlet chamber 100 and includes multiple descaling elements 31, each corresponding to one of the multiple liquid outlet sections 40. The faceplate mechanism 20 and the descaling assembly 30 can be brought close to each other so that the multiple descaling elements 31 fit against the multiple liquid outlet sections 40, disconnecting the liquid outlet hole 200 from the liquid outlet chamber 100. Alternatively, the faceplate mechanism 20 and the descaling assembly 30 can be moved away from each other so that the multiple descaling elements 31 are separated from the multiple liquid outlet sections 40, maintaining communication between the liquid outlet hole 200 and the liquid outlet chamber 100. The descaling component 31 can be fitted to the liquid outlet 40 with either an interference fit or a fit with a small gap. Both fits will block the liquid outlet 200, preventing liquid from flowing out immediately or dripping in small amounts, thus achieving immediate shut-off of the liquid outlet. Furthermore, after the liquid outlet 200 is blocked, air is prevented from entering the liquid outlet chamber 100, avoiding any changes in liquid quality or contamination that may occur due to prolonged contact between residual liquid and air.

[0063] The liquid dispensing system also includes a liquid inlet assembly. The rear cover mechanism 10 is provided with a connection structure 11 that connects to the liquid inlet assembly. The connection structure 11 can be connected to the liquid inlet assembly via, but is not limited to, threaded connection, plug-in connection, snap-fit ​​connection, or welding. The liquid inlet assembly is configured to supply liquid to the liquid dispensing device. The liquid inlet assembly can be, but is not limited to, a manually or electrically controlled valve structure; opening or closing the liquid inlet assembly connects or disconnects the liquid dispensing device from the liquid source. The liquid includes, but is not limited to, clean water or pure water from the municipal water network.

[0064] In summary, implementing the embodiments disclosed herein will have the following beneficial effects:

[0065] The liquid dispensing device described above is installed in the liquid dispensing system. Besides providing excellent cleaning performance, it also prevents scale buildup at the dispensing holes 200 and allows for immediate shut-off of the liquid dispensing. Specifically, the housing mechanism 20 and the descaling component 30 are positioned close to each other, so that multiple descaling elements 31 fit against multiple dispensing sections 40, disconnecting the dispensing holes 200 from the dispensing chamber 100. This allows the liquid to be discharged from the dispensing holes 200 more quickly as the descaling elements 31 approach the dispensing sections 40, flushing the dispensing holes 200, preventing scale formation, and easily removing existing scale and impurities from the dispensing holes 200. The fit between the descaling elements 31 and the dispensing sections 40 causes vibration or deformation of the dispensing sections 40, loosening existing scale and making it easier to be flushed away by the liquid. Furthermore, the descaling component 31 can block the liquid outlet 200, making it difficult for liquid to flow out of the liquid outlet 200, thus achieving immediate shut-off of liquid flow. The housing mechanism 20 and the descaling component 30 are spaced apart from each other, so that multiple descaling components 31 are separated from multiple liquid outlet sections 40, connecting the liquid outlet 200 with the liquid outlet chamber 100. The separation of the descaling component 31 from the liquid outlet section 40 will bring air into the liquid outlet 200, flushing away the scale and impurities that have formed, making it easier for them to be discharged from the liquid outlet 200 with the liquid. In addition, the air entering the liquid outlet 200 also causes the descaling component 31 to create suction on the liquid outlet section 40, causing the liquid outlet section 40 to vibrate or deform, which will also loosen the scale formed in the liquid outlet 200, making it easier to be flushed away by the liquid.

[0066] In the exemplary embodiments, please refer to Figure 2 , Figure 4 , Figure 8 , Figure 11 , Figure 17 , Figure 18 , Figure 20 and Figure 22The liquid outlet section 40 includes a circumferential wall 41 and a liquid outlet surface 42. The circumferential wall 41 and the liquid outlet surface 42 together form a liquid outlet groove 300. One end of the circumferential wall 41 is disposed on the face shell mechanism 20, connecting the liquid outlet groove 300 to the liquid outlet cavity 100. The liquid outlet surface 42 is disposed at the end of the circumferential wall 41 away from the liquid outlet cavity 100, and the liquid outlet hole 200 is disposed on the liquid outlet surface 42.

[0067] The shell mechanism 20 and the descaling assembly 30 can be brought close together so that multiple descaling components 31 are inserted one-to-one into multiple liquid outlet tanks 300 and abut against at least one of the corresponding circumferential wall 41 and liquid outlet surface 42, disconnecting the liquid outlet hole 200 from the liquid outlet chamber 100. During the insertion of the descaling component 31 into the liquid outlet tank 300, the liquid in the liquid outlet tank 300 can be discharged, preventing residual liquid in the liquid outlet tank 300 and reducing the likelihood of scale formation. Furthermore, during the insertion and removal of the descaling component 31 from the liquid outlet tank 300, under the action of atmospheric pressure, liquid surface tension, and the impact of the driving liquid on the liquid outlet section 40, the descaling component 31 will vibrate or deform, which helps to loosen the formed scale and facilitate its removal by the liquid. Furthermore, due to the presence of the liquid outlet 300, the liquid outlet 40 can concentrate the liquid, making it easier for it to be discharged from the liquid outlet 200 more quickly under the action of the descaling component 31.

[0068] like Figure 3 , Figure 8 , Figure 11 , Figure 14 , Figure 17 and Figure 18 As shown, the faceplate mechanism 20 includes a faceplate 21, a liquid outlet 22, and an inner frame 23. The faceplate 21 has multiple mounting holes 400. The liquid outlet 40 has a columnar structure, and each of the multiple liquid outlets 40 is installed in a one-to-one correspondence with one of the mounting holes 400 to ensure the stability of the position of the liquid outlet 40 relative to the faceplate 21. The liquid outlet 22 is disposed on one side of the faceplate 21 and, together with the inner frame 23, forms a liquid outlet cavity 100. The inner frame 23 is connected to the faceplate 21 and fixes the liquid outlet 22 to the faceplate 21. Multiple liquid outlets 40 are disposed on the liquid outlet 22.

[0069] like Figures 19 to 22 As shown, the faceplate mechanism 20 may also exclude the liquid outlet 22. The liquid outlet 40 may be integrated into the faceplate 21 and integrally formed with the faceplate 21.

[0070] In the exemplary embodiments, please refer to Figure 2 , Figure 4 , Figure 5 , Figure 8 , Figure 11 , Figure 17 , Figure 18 , Figure 20 and Figure 22The cross-sectional shape of the descaling component 31 is the same as that of the liquid outlet 300. This makes the driving force on the liquid in the liquid outlet 300 more uniform when the descaling component 31 moves towards the liquid outlet 40, and the suction force on the liquid outlet 40 more uniform when it moves out of the liquid outlet 300. This results in more uniform vibration or deformation of the liquid outlet 40 under the action of the descaling component 31, leading to better descaling effect. Furthermore, the liquid outlet 40 is less prone to plastic deformation, improving the reliability of the descaling component 31 in sealing the liquid outlet 200. In this embodiment, both the descaling component 31 and the liquid outlet 300 have circular cross-sections. It can be understood that in other embodiments, the cross-sections of the descaling component 31 and the liquid outlet 300 can also be regular shapes such as triangles, rectangles, solids, or ellipses, or they can be irregular shapes.

[0071] In the exemplary embodiments, please continue to refer to Figure 2 , Figure 4 , Figure 5 , Figure 8 , Figure 11 , Figure 17 , Figure 18 , Figure 20 and Figure 22 The radial dimension of the descaling component 31 is smaller than the radial dimension of the outlet tank 300. This creates at least a partial gap between the descaling component 31 and the circumferential wall 41, reducing the resistance of the liquid to the movement of the descaling component 31 relative to the outlet portion 40. This facilitates the smooth entry and exit of the descaling component 31 into and out of the outlet tank 300. Furthermore, the reduced resistance also reduces the pulling force of the descaling component 31 on the outlet portion 40, preventing the outlet portion 40 from undergoing plastic deformation that would prevent it from recovering and thus affecting the movement of the descaling component 31 relative to the outlet portion 40. It can be understood that in other embodiments, the radial dimension of the descaling component 31's cross-section can also be equal to or greater than the radial dimension of the outlet tank 300's cross-section. Utilizing the deformability of the descaling component 31 and / or the circumferential wall 41 ensures that the descaling component 31 can move relative to the outlet tank 300. In this case, the insertion dimension of the descaling component 31 into the outlet tank 300 should be appropriately reduced, thereby reducing the magnitude of the aforementioned resistance.

[0072] In this embodiment, the liquid outlet 40 is made of an elastomer, allowing it to vibrate and deform under the action of the descaling member 31, thus loosening the formed scale and facilitating its removal by liquid. Alternatively, in some embodiments, the liquid outlet 40 may be made of a rigid material, allowing it to vibrate under the action of the descaling member 31. The descaling member 31 is in contact with the liquid outlet surface 42, and the liquid outlet 40 can protrude away from the descaling member 31 to change the shape of the liquid outlet hole 200, further loosening the formed scale. The descaling member 31 has a contact surface 311 that is in contact with the liquid outlet surface, which can be, but is not limited to, a plane, an inclined plane, or an arc surface.

[0073] The number of liquid outlet holes 200 is four, and the diameter of the liquid outlet holes 200 can be approximately 0.2 mm to 0.5 mm, capable of forming a fine rain of liquid discharge. It can be understood that in other embodiments, the number of liquid outlet holes 200 can also be one, two, three, or more than four. The cross-sectional shape of the liquid outlet hole 200 perpendicular to the liquid flow direction can be circular (e.g., ...). Figure 2 (As shown), regular shapes such as ellipses, triangles, squares, trapezoids, parallelograms, or hexagons, or irregular shapes.

[0074] In the exemplary embodiments, please refer to Figure 5 , Figure 8 , Figure 11 , Figure 17 , Figure 18 , Figure 20 and Figure 22 The descaling assembly 30 also includes a body 32, on which multiple descaling components 31 are disposed. The body 32 is slidably connected to the faceplate mechanism 20, allowing the faceplate mechanism 20 and the descaling assembly 30 to move closer and further apart. By driving the body 32, the multiple descaling components 31 can synchronously move closer and further away from the multiple liquid outlets 40, ensuring the synchronicity of descaling and immediate shutdown. In other embodiments, the descaling assembly 30 can be understood as being fixedly connected to the faceplate mechanism 20 and the rear cover mechanism 10. The faceplate mechanism 20 can move relative to the rear cover mechanism 10, allowing the multiple descaling components 31 to synchronously move closer and further away from the multiple liquid outlets 40.

[0075] In the exemplary embodiments, please refer to Figure 5 , Figure 11 , Figure 17 , Figure 20 and Figure 22 The main body 32 is provided with a guide member 321, which engages with the face shell mechanism 20 to restrict the movement direction of the descaling component 30. This guide member 321 further increases the connection area between the main body 32 and the face shell mechanism 20, improving connection stability. Furthermore, the guiding engagement between the guide member 321 and the face shell mechanism 20 ensures the movement accuracy of the descaling component 30, thereby ensuring the contact accuracy between the multiple descaling components 31 and the multiple liquid outlets 40, guaranteeing the descaling and immediate shut-off effects.

[0076] In the exemplary embodiments, please refer to Figure 8 and Figure 17The rear cover mechanism 10 has a boss 12, and the front cover mechanism 20 has a guide hole 500. The guide member 321 passes through the guide hole 500. The front cover mechanism 20 is rotatably connected to the rear cover mechanism 10. When the front cover mechanism 20 rotates relative to the rear cover mechanism 10, it drives the guide member 321 to slide along the boss 12, so that the front cover mechanism 20 and the descaling assembly 30 can approach each other. In this way, the guide hole 500 allows the guide member 321 to contact the boss 12 through the guide hole 500. As the guide member 321 slides along the boss 12, it can change the distance between the multiple descaling components 31 and the multiple liquid outlets 40 according to the degree of outward protrusion of the boss 12 towards the front cover mechanism 20, until it fits into the multiple liquid outlets 40. The extension direction of the boss 12 matches the rotation trajectory of the guide 321 to ensure that the guide 321 can always contact the boss 12 as the multiple descaling components 31 approach the multiple liquid outlets 40, thus ensuring the smooth movement of the multiple descaling components 31 towards the multiple liquid outlets 40.

[0077] The faceplate mechanism 20 moves relative to the rear cover mechanism 10 via rotation, saving space required for this movement and making the liquid dispensing device more compact. To facilitate the rotation of the faceplate mechanism 20, a drive protrusion 24 is also provided on it, such as... Figure 1 As shown.

[0078] The guide member 321 is provided with a guide surface 322 that can guide and cooperate with the boss 12. In this way, the guide surface 322 can ensure a smoother cooperation between the guide member 321 and the boss 12.

[0079] The liquid dispensing device also includes a sealing component 50, which is disposed on the face shell mechanism 20 and sleeved on the guide member 321, providing a sliding seal with the guide member 321. This sealing component 50 ensures the sealing of the guide hole 500, preventing liquid from overflowing between the guide member 321 and the guide hole 500. Furthermore, the sealing component 50 increases the connection area between the guide member 321 and the face shell mechanism 20, improving the guiding stability between them. The sealing assembly 50 includes a cover 51 and a first seal 52. The first seal 52 is sleeved on the guide 321 and housed in a receiving groove 600 provided on the face shell mechanism 20. The first seal 52 is located between the guide 321 and the face shell mechanism 20. The cover 51 is connected to the face shell mechanism 20 and sleeved on the guide 321. The cover 51 can seal the receiving groove 600 to prevent the first seal 52 from moving out of the receiving groove 600. The guide 321 passes through the first seal 52 and exits from the cover 51 so as to be able to contact the boss 12.

[0080] In the exemplary embodiments, please refer to Figure 1 , Figure 3 , Figure 8 , Figure 9 , Figure 14 and Figure 15 The rear cover mechanism 10 is provided with a liquid inlet channel 700, which is configured to introduce liquid into the liquid outlet device. The liquid outlet device also includes a liquid distributor 60 and a liquid outlet mechanism 70. The liquid distributor 60 is disposed on the face shell mechanism 20 and together with the face shell mechanism 20 forms a first liquid distributor channel 801 and a second liquid distributor channel 802. The first liquid distributor channel 801 communicates with the liquid outlet chamber 100. The liquid outlet mechanism 70 is disposed on the face shell mechanism 20. The second liquid distributor channel 802 communicates with the liquid outlet mechanism 70. During the rotation of the face shell mechanism 20 relative to the rear cover mechanism 10, the liquid inlet channel 700 can communicate with one of the first liquid distributor channel 801 and the second liquid distributor channel 802. By communicating the liquid inlet channel 700 with the first liquid distributor channel 801 and the second liquid distributor channel 802 respectively, the liquid flow direction can be easily controlled to meet different liquid outlet effects. Liquid enters the outlet chamber 100 through the first liquid distribution channel 801 and exits through the outlet hole 200, forming a fine mist discharge. The faceplate mechanism 20 rotates relative to the rear cover mechanism 10, driving the guide member 321 to slide along the boss 12, so that the multiple descaling components 31 and multiple outlet parts 40 can approach each other until they fit together, blocking the outlet hole 200. At the same time, the faceplate mechanism 20 switches the connection between the inlet channel 700 and the first liquid distribution channel 801 to the connection between the inlet channel 700 and the second liquid distribution channel 802, allowing the outlet mechanism 70 to discharge liquid, forming other discharge effects. In this embodiment, the outlet mechanism 70 is a spray mechanism capable of forming a spray effect. It can be understood that in other embodiments, the outlet mechanism 70 can also be other outlet mechanisms 70, including but not limited to a rotating outlet mechanism 70 and a blade-type outlet mechanism 70.

[0081] In the exemplary embodiments, please refer to Figure 6 , Figure 9 and Figure 15 The rear cover mechanism 10 includes a rear cover assembly 13 and an elastic component 14. The elastic component 14 is disposed on the rear cover assembly 13 and has a through hole 900 that communicates with the liquid inlet channel 700. The elastic component 14 elastically abuts against the liquid distribution component 60.

[0082] During the rotation of the faceplate mechanism 20 relative to the rear cover mechanism 10, the elastic component 14 slides relative to the liquid distribution component 60, and the through hole 900 can communicate with one of the first liquid distribution channel 801 and the second liquid distribution channel 802. This ensures that during the rotation of the faceplate mechanism 20 relative to the rear cover mechanism 10, the elastic component 14 remains in contact with the liquid distribution component 60, preventing liquid from leaking out between the elastic component 14 and the liquid distribution component 60. This allows the liquid to have a specific flow direction under the constraint of the elastic component 14 and the liquid distribution component 60, ensuring that the liquid can stably flow into either the first liquid distribution channel 801 or the second liquid distribution channel 802.

[0083] The elastic component 14 includes a flexible element 141 and an elastic element 142. The flexible element 141 can elastically abut against the liquid distribution component 60. The flexible element 141 can better fit the liquid distribution component 60 through its own deformation, thereby improving the sealing performance between the elastic component 14 and the liquid distribution component 60. The rear cover assembly 13 includes a rear cover 131, an inlet pipe 132, and a connector 133. The inlet pipe 132 is disposed on the rear cover 131 and connected to the connector 133. The inlet flow channel 700 passes through the inlet pipe 132 and the connector 133 in sequence. The connector 133 is provided with a mounting groove 1000 communicating with the inlet flow channel 700. The elastic element 142 is installed in the mounting groove 1000 and supported between the connector 133 and the flexible element 141, so as to further enhance the elastic abutment force of the flexible element 141 on the liquid distribution component 60, thereby further improving the sealing stability between the elastic component 14 and the liquid distribution component 60. A through-hole 900 passes through the flexible member 141 and communicates with the liquid inlet channel 700 via the mounting groove 1000. The flexible member 141 may be made of, but is not limited to, rubber. The elastic member 142 may be, but is not limited to, a metal spring or a plastic spring.

[0084] In the exemplary embodiments, please refer to Figure 6 , Figure 8 and Figure 14 One of the rear cover mechanism 10 and the front shell mechanism 20 is provided with a positioning component 80, and the other is provided with a positioning element. The positioning element is provided with a first positioning part 1101 and a second positioning part 1102. The first positioning part 1101 and the second positioning part 1102 are configured to cooperate with the positioning component 80 to perform positioning when the multiple descaling parts 31 are in contact with or separated from the multiple liquid outlet parts 40, so that the state of contact or separation of the multiple descaling parts 31 and the multiple liquid outlet parts 40 corresponding to each preset position can be sensed by whether the front shell mechanism 20 has rotated to a preset position.

[0085] The positioning assembly 80 includes a mounting component 81, an abutting component 82, and an elastic component 83. The mounting component 81 is disposed on one of the rear cover mechanism 10 and the front cover mechanism 20, and the mounting component 81 has a mounting space 1200. The abutting component 82 is partially located in the mounting space 1200 and can be slidably connected with the positioning component. The elastic component 83 is installed in the mounting space 1200 and can abut the abutting component 82 against the positioning component. The elastic component 83 ensures a tighter fit between the abutting component 82 and the positioning component, preventing gaps between them that could cause abnormal noise when the abutting component 82 slides against the positioning component.

[0086] In this embodiment, the first positioning part 1101 and the second positioning part 1102 are groove structures. The elastic member 83 can also make the abutting member 82 relatively stably positioned within the groove structure, improving the accuracy of position sensing. The elastic member 83 may be, but is not limited to, a metal spring or a plastic spring. The mounting member 81 has a columnar structure and is disposed on the rear cover mechanism 10. The positioning member is integrated into the liquid distribution member 60.

[0087] In the exemplary embodiments, please refer to Figures 19 to 22 The faceplate mechanism 20 is provided with a guide hole 500 and a flow hole 1300. The guide member 321 passes through the guide hole 500 and is connected to the pressure cap 90. In this way, the guide hole 500 allows the guide member 321 to contact the boss 12 through the guide hole 500.

[0088] The pressure cap 90 is sleeved on the outer circumferential side of the guide member 321. The pressure cap 90 is attached to the face shell mechanism 20 and covers the flow hole 1300.

[0089] The pressure cap 90 is configured to separate from the faceplate mechanism 20 under the drive of liquid entering the liquid outlet chamber 100, so that the liquid outlet chamber 100 is connected through the flow hole 1300 and drives the guide member 321 to move the faceplate mechanism 20 and the descaling assembly 30 away from each other. This allows the separation of the multiple descaling components 31 from the multiple liquid outlet sections 40 to be liquid-driven. Liquid can enter between the pressure cap 90 and the faceplate mechanism 20 where the flow hole 1300 is located, and the liquid creates pressure to separate the pressure cap 90 from the faceplate mechanism 20.

[0090] In this embodiment, the faceplate mechanism 20 is provided with an annular wall 91, and the pressure cap 90 is housed in the space enclosed by the annular wall 91 and slidably sealed with the annular wall 91. The annular wall 91 is provided with a through hole 1400 communicating with the liquid outlet chamber 100. The through hole 1400 is configured to allow liquid entering the liquid outlet chamber 100 to enter the space enclosed by the annular wall 91 to drive the pressure cap 90. Thus, the annular wall 91 makes it easier for liquid to generate pressure between the pressure cap 90 and the faceplate mechanism 20 where the through hole 1300 is located, increasing the speed at which the pressure cap 90 separates from the faceplate mechanism 20 and reducing the water outlet response time of the liquid outlet 200. The pressure cap 90 is sleeved on the circumferential outer side of the guide member 321, which increases the contact area with the liquid, thereby further increasing the speed at which the pressure cap 90 separates from the faceplate mechanism 20. To improve the pressure-holding effect, a second sealing member 92 can also be provided between the pressure cap 90 and the annular wall 91.

[0091] In an exemplary embodiment, the liquid dispensing device further includes a reset member 15, which is disposed on the faceplate mechanism 20 and is configured to generate a driving force for resetting the descaling assembly 30.

[0092] Please combine them together Figure 3 , Figure 4 , Figure 12 and Figure 18 The reset element 15 is a helical spring, clamped between the face shell mechanism 20 and the descaling assembly 30. The face shell mechanism 20 is provided with a connecting post 25, and the descaling assembly 30 is provided with a connecting groove 1500 opposite to the connecting post 25. One end of the reset element 15 is sleeved on the connecting post 25, and the other end is received in the connecting groove 1500 to ensure the stability of the position of the reset element 15, thereby ensuring the driving direction accuracy of the descaling assembly 30.

[0093] During the rotation of the faceplate mechanism 20 relative to the rear cover mechanism 10, the guide member 321 slides along the boss 12, causing the multiple descaling components 31 to move closer to the multiple liquid outlets 40. The reset member 15 is compressed, generating a driving force for the descaling assembly 30 to reset (this driving force causes the multiple descaling components 31 to tend to move away from the multiple liquid outlets 40), and ensuring that the guide member 321 and the boss 12 are in close contact, guaranteeing the fitting accuracy between the guide member 321 and the boss 12. As the guide member 321 slides along the boss 12, when the outward convexity of the boss 12 towards the faceplate mechanism 20 gradually decreases, the reset member 15 can drive the multiple descaling components 31 away from the multiple liquid outlets 40, thereby resetting the descaling assembly 30. In addition, in some exemplary embodiments, the reset member 15 can also be a magnetic attractor, which drives the descaling assembly 30 to reset by generating a magnetic attraction force on the descaling assembly 30.

[0094] Please combine them together Figure 20 and Figure 21The reset element 15 is a helical spring, clamped between the faceplate mechanism 20 and the descaling component 30. The faceplate mechanism 20 is provided with a positioning groove 1600. The reset element 15 is sleeved on the guide member 321, with one end received in the positioning groove 1600, to ensure the stability of the reset element 15's position, thereby ensuring the driving direction accuracy of the descaling component 30. Thus, under the action of the liquid and the reset element 15, multiple descaling components 31 and multiple liquid outlets 40 can automatically separate and automatically adhere, achieving automatic descaling and automatic shut-off / stop effects. This is simple and convenient, and can better solve problems such as blockage of the liquid outlet 200, oblique liquid discharge, and continuous dripping of residual liquid.

[0095] Under the influence of the liquid entering the outlet chamber 100, the pressure cap 90 separates from the faceplate mechanism 20, causing the multiple descaling components 31 to separate towards the multiple outlet sections 40. The reset member 15 is compressed, generating a driving force for the descaling assembly 30 to reset (this driving force causes the multiple descaling components 31 to tend to approach the multiple outlet sections 40). Furthermore, in some exemplary embodiments, the reset member 15 may also be a magnetic element, generating a magnetic attraction force on the descaling assembly 30 to drive it to reset.
