Among them, the liquid discharging device includes a housing 10, a front shell assembly 20, a plurality of liquid discharging parts 40 and a movable part 30. The front shell assembly 20 and the housing 10 enclose a liquid inlet cavity 100. Each liquid discharging part 40 extends along a first direction and protrudes from the front shell assembly 20. Each liquid discharging part 40 is provided with at least one liquid discharging hole 200, and the liquid discharging hole 200 communicates with the liquid inlet cavity 100.

[0054] In the embodiments of the present disclosure, each liquid discharging part 40 is provided with a plurality of liquid discharging holes 200. The aperture of the liquid discharging hole 200 is relatively small, and its diameter range can be about 0.2 mm to 0.8 mm. It can be understood that in other embodiments, the diameter range of the liquid discharging hole 200 can also be other numerical ranges, so that the design of multiple liquid discharging holes 200 of the liquid discharging part 40 is softer in liquid discharging than the design of a single liquid discharging hole 200 under the same liquid discharging volume. In addition, each liquid discharging part 40 can also be provided with one liquid discharging hole 200.

[0055] The movable member 30 is movably mounted on the housing 10 and / or the front shell assembly 20. The movable member 30 is provided with a plurality of abutting portions 50, and the plurality of abutting portions 50 are respectively and annularly disposed on the outer circumference of the plurality of liquid outlet portions 40. The movable member 30 is arranged to be able to approach or move away from the front shell assembly 20 in a first direction, so that each abutting portion 50 can abut against the outer circumference of the corresponding liquid outlet portion 40.

[0056] The liquid outlet system further includes a liquid inlet assembly. A connection structure connected to the liquid inlet assembly is provided on the housing 10.

The liquid inlet assembly can be, but not limited to, a valve structure controlled manually or electrically. By opening or closing the liquid inlet assembly, the communication or disconnection between the liquid outlet hole 200 and the liquid source is realized. The liquid includes, but is not limited to, clear water or pure water from the municipal water network.

[0057] In summary, implementing the embodiments of the present disclosure will have the following beneficial effects: The liquid outlet device of the above solution is applied to the liquid outlet system. In addition to enabling the liquid outlet system to have excellent cleaning efficiency, it can also perform descaling operations on the liquid outlet holes 200 to prevent the liquid outlet holes 200 from being blocked by scale. Specifically, the liquid outlet device includes a housing 10, a front shell assembly 20, a plurality of liquid outlet portions 40 and a movable member 30. Among them, the front shell assembly 20 and the housing 10 enclose a liquid inlet cavity 100. Each liquid outlet portion 40 extends in the first direction and protrudes from the front shell assembly 20. Each liquid outlet portion 40 is provided with at least one liquid outlet hole 200, and the liquid outlet hole 200 communicates with the liquid inlet cavity 100 to facilitate the liquid outlet of the liquid outlet device. The movable member 30 is provided with a plurality of abutting portions 50, and the plurality of abutting portions 50 are respectively and annularly disposed on the outer circumference of the plurality of liquid outlet portions 40. The movable member 30 is arranged to be able to approach or move away from the front shell assembly 20 in a first direction, so that each abutting portion 50 can abut against the outer circumference of the corresponding liquid outlet portion 40, and the abutting action is used to drive the liquid outlet portion 40 to vibrate (the liquid outlet portion 40 is made of a hard material or an elastomeric material) to shake off the scale, or the abutting action is used to drive the liquid outlet portion 40 to elastically deform (the liquid outlet portion 40 is made of an elastomeric material) to change the shape of the liquid outlet hole 200, so that the scale falls off.

[0058] In the embodiments of the present disclosure, the liquid outlet portion 40 is made of an elastomeric material and can vibrate or elastically deform under the driving of the abutting action of the abutting portion 50 to make the scale fall off.

[0059] In an exemplary embodiment, please also combine Figures 3 to 5 and Figure 8, the radial dimension of the liquid outlet portion 40 gradually narrows or widens along the first direction. In this way, when the abutting portion 50 approaches or moves away from the front shell assembly 20 along with the movable member 30, the distance between the abutting portion 50 and the circumferential outer side of the corresponding liquid outlet portion 40 will gradually decrease until the abutting portion 50 abuts against the circumferential outer side of the corresponding liquid outlet portion 40. Under the driving of the abutting action, the liquid outlet portion 40 vibrates or undergoes elastic deformation to shake off the scale or change the shape of the liquid outlet holes 200, so that the scale falls off. During the reset process of the movable member 30, the abutting force of the abutting portion 50 acting on the corresponding liquid outlet portion 40 gradually decreases until the abutting portion 50 separates from the liquid outlet portion 40. After that, the distance between the abutting portion 50 and the circumferential outer side of the corresponding liquid outlet portion 40 will gradually increase until the movable member 30 returns to its original position, avoiding the abutting portion 50 from affecting the normal liquid discharge of the liquid outlet portion 40 and facilitating the abutting portion 50 to abut against the corresponding liquid outlet portion 40 again for descaling operation.

[0060] In the embodiment of the present disclosure, the radial dimension of the liquid outlet portion 40 gradually narrows along the first direction. When the abutting portion 50 approaches the front shell assembly 20 along with the movable member 30, the distance between the abutting portion 50 and the circumferential outer side of the corresponding liquid outlet portion 40 will gradually decrease until the abutting portion 50 abuts against the circumferential outer side of the corresponding liquid outlet portion 40 for descaling operation.

[0061] It can be understood that in other embodiments, the radial dimension of the liquid outlet portion 40 gradually widens along the first direction. When the abutting portion 50 moves away from the front shell assembly 20 along with the movable member 30, the distance between the abutting portion 50 and the circumferential outer side of the corresponding liquid outlet portion 40 will gradually decrease until the abutting portion 50 abuts against the circumferential outer side of the corresponding liquid outlet portion 40 for descaling operation.

[0062] In the embodiment of the present disclosure, the circumferential outer side of the liquid outlet portion 40 is a conical surface. It can be understood that in other embodiments, the circumferential outer side of the liquid outlet portion 40 can also be a pyramid surface, or the circumferential outer side of the liquid outlet portion 40 can also have a plurality of planes or arc surfaces inclined with respect to the first direction. At least some of the adjacent planes among the plurality of planes are not connected to each other. At least some of the adjacent arc surfaces among the plurality of arc surfaces are not connected to each other.

[0063] In an exemplary embodiment, please also refer to Figures 3 to 5, the radial dimension of the space surrounded by the abutting portion 50 gradually narrows or widens along the first direction, and the radial dimension of the small end of the abutting portion 50 matches that of the small end of the liquid outlet portion 40. In this way, it is convenient for the abutting portion 50 to abut against or separate from the circumferential outer side of the corresponding liquid outlet portion 40 during the movement of the abutting portion 50 relative to the liquid outlet portion 40. Moreover, the abutting portion 50 can also limit the small end of the liquid outlet portion 40 after the moving member 30 is reset, improving the structural stability of the liquid outlet portion 40 and ensuring the liquid outlet effect. Especially when the radial dimension of the liquid outlet portion 40 gradually narrows along the first direction, the small end of the liquid outlet portion 40 is located at the free end of the liquid outlet portion 40. After the moving member 30 is reset, the abutting portion 50 can limit the small end of the liquid outlet portion 40, and during the liquid outlet process, it can prevent the small end of the liquid outlet portion 40 from swinging too much and affecting the liquid outlet effect.

[0064] In addition, in some embodiments, the radial dimension of the space surrounded by the abutting portion 50 may also remain unchanged, or the amplitude of gradually narrowing or gradually widening along the first direction is smaller than that of the liquid outlet portion 40 along the first direction, so as to reduce the moving distance of the moving member 30 during the process of the abutting portion 50 abutting against the circumferential outer side of the liquid outlet portion 40 or separating from the liquid outlet portion 40, reduce the driving duration of the hand on the moving member 30 during the descaling process, and reduce the hand fatigue.

[0065] In an exemplary embodiment, please also combine with Figures 3 to 6 , the moving member 30 has a plurality of through holes 300, and a plurality of liquid outlet portions 40 are respectively inserted through the plurality of through holes 300. The abutting portion 50 is formed on the hole wall 301 of the through hole 300. The abutting portion 50 can be a part or the whole of the hole wall 301, or can be an outward convex structure provided on the hole wall 301. The abutting portion 50 can be in an overall annular shape. The abutting portion 50 can also include a plurality of annularly distributed abutting surfaces or abutting protrusions, wherein the plurality of abutting surfaces or abutting protrusions can be connected as a whole or formed at intervals on the hole wall 301 and surround the circumferential outer side of the corresponding liquid outlet portion 40.

[0066] In an exemplary embodiment, please also combine with Figures 3 to 7, a first limiting portion 60 is provided on the housing 10 or the front shell assembly 20, and a second limiting portion 80 is provided on the movable member 30. The first limiting portion 60 can be disposed opposite to the second limiting portion 80 in the first direction to limit the distance of the movable member 30 from the front shell assembly 20 in the first direction. When the movable member 30 moves away from the front shell assembly 20 in the first direction, the first limiting portion 60 and the second limiting portion 80 can approach and abut against each other to form a limiting fit. Thus, through the settings of the first limiting portion 60 and the second limiting portion 80, the overall separation of the movable member 30 from the housing 10 and the front shell assembly 20 can be avoided, which affects descaling. And when the movable member 30 moves closer to the front shell assembly 20 in the first direction, it can also be restricted by the housing 10 or the front shell assembly 20. Therefore, the cooperation of the first limiting portion 60 and the second limiting portion 80 and the cooperation of the movable member 30 and the housing 10 or the front shell assembly 20 can also limit the movement range of the movable member 30 relative to the front shell assembly 20, ensuring that descaling operations can be carried out in a timely manner when descaling is required. Both the first limiting portion 60 and the second limiting portion 80 are convex structures. In the embodiment of the present disclosure, the first limiting portion 60 is provided on the front shell assembly 20.

[0067] In an exemplary embodiment, please continue to refer to Figures 3 to 7 , a guiding groove 400 is provided on the side of the movable member 30 facing the first limiting portion 60. The guiding groove 400 extends in the first direction, and the first limiting portion 60 can be at least partially received in the guiding groove 400.

[0068] During the process of the movable member 30 moving closer to or away from the front shell assembly 20 in the first direction, the first limiting portion 60 can slide along the guiding groove 400, moving away from or closer to the second limiting portion 80. In this way, the movable member 30 can move in the first direction under the restriction of the first limiting portion 60 located on the housing 10 or the front shell assembly 20, avoiding the rotation of the movable member 30 relative to the front shell assembly 20, thereby ensuring the centering accuracy between the abutting portion 50 and the corresponding liquid outlet portion 40, ensuring that the abutting force acts more uniformly on the circumferential outer side of the liquid outlet portion 40, and ensuring the descaling effect. And, it also enables the first limiting portion 60 to play a guiding and anti-rotation role in addition to cooperating with the second limiting portion 80 for limiting, further simplifying the structure of the liquid outlet device and reducing the cost.

[0069] It can be understood that in other embodiments, a guiding groove 400 is provided on the side of the housing 10 or the front housing assembly 20 facing the second limiting portion 80. The guiding groove 400 extends along the first direction, and the second limiting portion 80 can be at least partially received in the guiding groove 400. During the process of the moving member 30 approaching or departing from the front housing assembly 20 along the first direction, the second limiting portion 80 can slide along the guiding groove 400, moving away from or approaching the first limiting portion 60. In this way, the moving member 30 can pass through the second limiting portion 80 and move along the first direction under the limitation of the housing 10 or the front housing assembly 20, preventing the moving member 30 from rotating relative to the front housing assembly 20, thereby ensuring the centering accuracy between the abutting portion 50 and the corresponding liquid outlet portion 40, ensuring that the abutting force acts more uniformly on the outer circumference of the liquid outlet portion 40, and ensuring the descaling effect. Moreover, it also enables the second limiting portion 80 to play a guiding and anti-rotation role in addition to cooperating with the first limiting portion 60 for limiting, further simplifying the structure of the liquid outlet device and reducing the cost.

[0070] In an exemplary embodiment, please continue to refer to Figures 3 to 7 , the moving member 30 is provided with an elastic arm 31, the second limiting portion 80 is arranged on the elastic arm 31, and the elastic arm 31 is configured to be elastically deformable so that the second limiting portion 80 can cross the limitation of the first limiting portion 60. In this way, by utilizing the elastic deformation ability of the elastic arm 31, it is convenient for the second limiting portion 80 to cross the first limiting portion 60 during the installation process of the moving member 30 and the housing 10 or the front housing assembly 20. After the elastic arm 31 returns to its original state, the second limiting portion 80 is reset and is arranged opposite to the first limiting portion 60 along the first direction, capable of forming a limiting cooperation. Moreover, at least part of the first limiting portion 60 or the second limiting portion 80 can be received in the guiding groove 400 to form a guiding and anti-rotation cooperation. During the process of the overall separation of the moving member 30 from the housing 10 and the front housing assembly 20, an external force can be applied to the elastic arm 31 to cause the elastic arm 31 to elastically deform. At this time, the orthographic projection of the second limiting portion 80 along the first direction on the side of the first limiting portion 60 does not overlap with the first limiting portion 60, and the second limiting portion 80 can cross the first limiting portion 60, enabling the moving member 30 to be separated from the housing 10 and the front housing assembly 20 as a whole. In the embodiment of the present disclosure, the elastic arm 31 is arranged on the side of the moving member 30 facing the front housing assembly 20. The second limiting portion 80 is arranged on the side of the elastic arm 31 facing the first limiting portion 60.

[0071] In the embodiment of the present disclosure, the number of the elastic arms 31 is multiple. The multiple elastic arms 31 are arranged at intervals and surround the first direction on the moving member 30. At least one second limiting portion 80 and at least one guiding groove 400 are provided on each elastic arm 31. The front housing assembly 20 is provided with a first limiting portion 60 corresponding to the guiding groove 400.
