[0053] After the existing liquid discharging device is used, the residual liquid is likely to scale at the liquid discharging hole, block the liquid discharging hole, and affect the liquid discharging of the liquid discharging device.

[0054] Embodiments of the present disclosure provide a liquid discharging device and a liquid discharging system.

The liquid discharging device can be, but is not limited to, a water tap, a shower head, or a spray gun. For the convenience of describing the technical solutions of the present disclosure, the following takes the liquid discharging device as a shower head as an example for illustration.

[0055] Please also combine with Figures 1 to 6 , the liquid outlet system provided by the embodiments of the present disclosure will now be described. The liquid outlet system includes a liquid outlet device. Among them, the liquid outlet device includes a housing 10, a front shell assembly 20 and a movable member 30. The front shell assembly 20 and the housing 10 enclose a liquid inlet cavity 100. The front shell assembly 20 is provided with a plurality of liquid outlet parts 40, and each liquid outlet part 40 is provided with at least one liquid outlet hole 200, and the liquid outlet hole 200 communicates with the liquid inlet cavity 100. In the embodiments of the present disclosure, each liquid outlet part 40 is provided with a plurality of liquid outlet holes 200. The aperture of the liquid outlet hole 200 is 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 outlet hole 200 can also be other numerical ranges, so that the design of multiple liquid outlet holes 200 of the liquid outlet part 40 is more gentle in liquid outlet than the design of a single liquid outlet hole 200 under the same liquid outlet volume. In addition, each liquid outlet part 40 may also be provided with a single liquid outlet hole 200.

[0056] The movable member 30 is rotatably connected to the housing 10 or the front shell assembly 20. The movable member 30 is provided with an abutting portion 50. During the rotation of the movable member 30 relative to the front shell assembly 20, the abutting portion 50 can abut against the circumferential outer side of at least one liquid outlet part 40.

[0057] The liquid outlet system further includes a liquid inlet assembly. The housing 10 is provided with a connection structure connected to the liquid inlet assembly. The connection part structure can be connected to the liquid inlet assembly by, but not limited to, threaded connection, plug connection, snap connection or welding. The liquid inlet assembly is configured to supply liquid to the liquid inlet cavity 100. 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, clean water or pure water from a municipal water network.

[0058] 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 scale the liquid outlet holes 200 to avoid scaling and blockage of the liquid outlet holes 200. Specifically, the liquid outlet device includes a housing 10, a front shell assembly 20, and a movable member 30. Among them, the front shell assembly 20 and the housing 10 enclose a liquid inlet cavity 100. The front shell assembly 20 is provided with a plurality of liquid outlet parts 40, and each liquid outlet part 40 is provided with at least one liquid outlet hole 200 communicating with the liquid inlet cavity 100 to facilitate the liquid outlet of the liquid outlet device. The movable member 30 is provided with an abutting part 50. During the rotation of the movable member 30 relative to the front shell assembly 20, the abutting part 50 can abut against the circumferential outer side of at least one liquid outlet part 40, and the abutting action is used to drive the liquid outlet part 40 to vibrate (the liquid outlet part 40 is made of a hard material or an elastomer material) to shake off the scale, or the abutting action is used to drive the liquid outlet part 40 to elastically deform (the liquid outlet part 40 is made of an elastomer material) to change the shape of the liquid outlet hole 200 and make the scale fall off.

[0059] In the embodiments of the present disclosure, the liquid outlet part 40 is made of an elastomer material and can vibrate or elastically deform under the driving of the abutting action of the abutting part 50 to make the structure fall off.

[0060] In an exemplary embodiment, the abutting part 50 can be a strip-shaped structure or an arc-shaped structure, and can rotate clockwise or counterclockwise relative to the front shell assembly 20 with the movable member 30 and abut against one or a plurality of liquid outlet parts 40 at the same time. For example, the abutting part 50 can be a strip-shaped structure extending along the radial direction of the movable member 30. The number of the abutting parts 50 can be one, and it can rotate clockwise or counterclockwise relative to the front shell assembly 20 with the movable member 30 for one week to sweep across all the liquid outlet parts 40. The liquid outlet part 40 can elastically deform under the driving of the abutting action of the abutting part 50, and after increasing the abutting force of the abutting part 50 acting on the liquid outlet part 40, the abutting part 50 can cross over the liquid outlet part 40 and continue to rotate clockwise or counterclockwise to sweep across all the liquid outlet parts 40.

[0061] In addition, the number of the abutting portions 50 can be multiple, and the shape of the abutting portions 50 can be matched according to the distribution shape of the multiple liquid outlet portions 40. For example, the multiple liquid outlet portions 40 include multiple groups of liquid outlet portion groups, and each group of liquid outlet portion groups includes at least two liquid outlet portions 40 distributed linearly or in an arc shape along the radial direction of the surface shell assembly 20. Correspondingly, the abutting portions 50 can be strip-shaped structures or arc-shaped structures. The multiple abutting portions 50 are arranged around the axis of the movable member 30. In this way, while ensuring that each liquid outlet portion 40 can be abutted by the abutting portion 50, the rotation angle of the movable member 30 can be reduced, and it can also be avoided that the abutting portion 50 crosses over the liquid outlet portion 40, reducing the deformation amount of the liquid outlet portion 40 and improving the service life of the liquid outlet portion 40. At this time, the movable member 30 can be a shaft structure, and the multiple abutting portions 50 are arranged around the movable member 30.

[0062] In an exemplary embodiment, please also refer to Figure 5 , Figure 6 and Figure 8 , the movable member 30 has multiple through holes 300, and the multiple liquid outlet portions 40 are respectively passed through the multiple through holes 300 in a one-to-one correspondence. The abutting portion 50 is formed on the hole wall 301 of the through hole 300. In this way, the number of the abutting portions 50 can be matched with the number of the liquid outlet portions 40 and can be an integer multiple of the number of the liquid outlet portions 40. For example, the movable member 30 can rotate reciprocally clockwise and counterclockwise, and the two sides of the hole wall 301 located on the rotation path of the movable member 30 can respectively form the abutting portions 50 that abut against the liquid outlet portions 40.

[0063] The number of the abutting portions 50 can be an integer multiple of the number of the liquid outlet portions 40, so that each liquid outlet portion 40 can correspond to one or more abutting portions 50, ensuring the abutting effect of each liquid outlet portion 40, and further ensuring the descaling effect of each liquid outlet hole 200. Moreover, the setting of the through holes 300 can also play a positioning role for the liquid outlet portions 40, ensuring the stability of the liquid outlet portions 40 when discharging liquid.

[0064] The abutting portion 50 can be a part or the whole of the hole wall 301, or can be a convex structure arranged on the hole wall 301.

[0065] In an exemplary embodiment, the hole wall 301 is in clearance fit with the circumferential outer side of the liquid outlet portion 40. During the rotation of the movable member 30 relative to the front housing assembly 20, two or more abutting positions are formed between the hole wall 301 and the circumferential outer side of the liquid outlet portion 40. For example, when the shapes of the hole wall 301 and the circumferential outer side of the liquid outlet portion 40 are the same, the two sides of the hole wall 301 located on the rotation path of the movable member 30 can respectively form abutting portions 50 abutting against the liquid outlet portion 40. When the shapes of the hole wall 301 (such as cylindrical) and the circumferential outer side of the liquid outlet portion 40 (such as square) are different, during the reciprocating movement of the movable member 30 in the clockwise and counterclockwise directions, the two sides of the hole wall 301 located on the rotation path of the movable member 30 can respectively form two abutting portions 50 abutting against the two tips on one side of the liquid outlet portion 40. In the case where the hole wall 301 is in clearance fit with the circumferential outer side of the liquid outlet portion 40, the liquid outlet portion 40 can be made of a hard material or an elastomeric material.

[0066] It can be understood that in other embodiments, the hole wall 301 is in interference fit with the circumferential outer side of the liquid outlet portion 40. In the case where the hole wall 301 is in interference fit with the circumferential outer side of the liquid outlet portion 40, the liquid outlet portion 40 can be made of an elastomeric material, and the liquid outlet portion 40 can be elastically deformed instantaneously when the movable member 30 rotates relative to the front housing assembly 20, so as to change the shape of the liquid outlet hole 200 and make the scale fall off.

[0067] In an exemplary embodiment, please also combine Figure 5 , Figure 6 and Figure 9 , the housing 10 or the front housing assembly 20 is provided with a first limiting portion 60, and the movable member 30 is provided with a second limiting portion 400. The first limiting portion 60 can cooperate with the second limiting portion 400 to limit the rotation angle of the movable member 30 relative to the front housing assembly 20. Thus, through the arrangement of the first limiting portion 60 and the second limiting portion 400, the movable member 30 can rotate relative to the front housing assembly 20 within a certain angle range, avoiding excessive rotation angle of the movable member 30 relative to the front housing assembly 20, causing damage to the liquid outlet portion 40, and even causing the liquid outlet portion 40 to escape from the through hole 300 and unable to reset. One of the first limiting portion 60 and the second limiting portion 400 is a convex structure, and the other has a groove structure.

[0068] In an exemplary embodiment, please also combine Figures 1 to 6 , the movable member 30 includes a panel 31, and the panel 31 is rotatably connected to the housing 10 or the front housing assembly 20. A plurality of through holes 300 penetrate through the panel 31. The panel 31 is provided with a driving portion 32. Thus, through the arrangement of the driving portion 32, it is convenient to drive the panel 31 to rotate relative to the front housing assembly 20 to perform descaling operations on a plurality of liquid outlet holes 200 simultaneously. The driving portion 32 is located outside the liquid outlet device for convenient finger operation.

[0069] In an exemplary embodiment, please also combineFigure 2 , Figure 5 , Figure 6 and Figure 7 , the movable member 30 further includes a circumferential wall 33 which is disposed around the circumferential outer side of the panel 31. An annular groove 500 is provided between the circumferential outer side of the front shell assembly 20 and the housing 10, and the circumferential wall 33 is inserted into the annular groove 500, so that the connection surface area between the movable member 30 and the front shell assembly 20 and the housing 10 can be increased, and the connection stability can be improved. During the rotation of the movable member 30 relative to the front shell assembly 20, the circumferential wall 33 can rotate relative to the front shell assembly 20 along the annular groove 500, thereby improving the rotation stability of the movable member 30 relative to the front shell assembly 20.

[0070] In the embodiment of the present disclosure, the panel 31 and the front shell assembly 20 are sequentially arranged along the axial direction of the panel 31, and the driving portion 32 is located on the side of the panel 31 away from the front shell assembly 20.

[0071] It can be understood that in other embodiments, the panel 31 can be embedded in the front shell assembly 20, that is, the front shell assembly 20 can clamp the two opposite sides of the panel 31 along its axial direction, and the front shell assemblies 20 located on both axial sides of the panel 31 both have annular grooves 500, and the circumferential walls 33 are respectively inserted into the two annular grooves 500. The driving portion 32 is disposed on the side of the circumferential wall 33 away from the panel 31 and extends out of the housing 10.

[0072] In an exemplary embodiment, please also refer to Figure 2 , Figure 5 and Figure 7 , a ring-shaped wall 70 is provided around the circumferential outer side of the front shell assembly 20, and the ring-shaped wall 70 can be hermetically connected to the housing 10 to ensure the sealing performance between the front shell assembly 20 and the housing 10 and prevent liquid from flowing out between the front shell assembly 20 and the housing 10. The ring-shaped wall 70 can be hermetically connected to the housing 10, which can make a part of the circumferential outer side of the front shell assembly 20 spaced from the housing 10 to form an annular groove 500. In the embodiment of the present disclosure, the housing 10 has an enclosing wall 11 which surrounds the front shell assembly 20 and the movable member 30, and the ring-shaped wall 70 can be hermetically attached to the enclosing wall 11 to achieve the sealing connection between the ring-shaped wall 70 and the housing 10. The enclosing wall 11 is spaced from a part of the circumferential outer side of the front shell assembly 20 to form an annular groove 500. The circumferential wall 33 is inserted into the annular groove 500 and can rotate relative to the front shell assembly 20 along the annular groove 500 under the limitation of the enclosing wall 11 and the front shell assembly 20.

[0073] In an exemplary embodiment, please also refer to Figure 5 and Figure 6, a protrusion 34 is provided between the panel 31 and the front shell assembly 20. The protrusion 34 is provided on one of the panel 31 and the front shell assembly 20 and abuts against the other of the panel 31 and the front shell assembly 20. In this way, the connection stability between the panel 31 and the front shell assembly 20 can be ensured through the setting of the protrusion 34, ensuring that the panel 31 and the front shell assembly 20 can be closely matched, avoiding a loose feeling caused by assembly errors when the panel 31 and the front shell assembly 20 are in surface contact. Moreover, the setting of the protrusion 34 can also reduce the connection surface area between the panel 31 and the front shell assembly 20, reduce the sliding resistance, and facilitate the rotation of the movable member 30 relative to the front shell assembly 20. In the embodiment of the present disclosure, the protrusion 34 is annular and the number is two. The two protrusions 34 are both coaxial with the axis of the panel 31 and are arranged in sequence along the radial direction of the panel 31, further ensuring the force stability between the panel 31 and the front shell assembly 20. It can be understood that in other embodiments, the number of the protrusions 34 can also be one or more than three. The protrusion 34 can also be a non-annular structure such as a dot or an arc.

[0074] In an exemplary embodiment, please also combine Figure 2 , Figure 5 , Figure 6 and Figure 7 , the front shell assembly 20 has a groove wall 601 forming an installation groove 600. The housing 10 is provided with a connection portion 12, and the connection portion 12 passes through the installation groove 600. In the embodiment of the present disclosure, the middle part of the front shell assembly 20 has an installation groove 600, and a connection portion 12 is provided on the side of the housing 10 facing the front shell assembly 20. The movable member 30 further includes an annular structure 35. The annular structure 35 is provided on the panel 31. The annular structure 35 is installed in the installation groove 600 and is connected to the connection portion 12, so that the installation groove 600, the connection portion 12 and the annular structure 35 are coaxially arranged. The connection portion 12 is in a columnar structure.

[0075] Both sides of the annular structure 35 along its radial direction are respectively attached to the groove wall 601 and the connection portion 12 to prevent the movable member 30 from moving axially along its radial direction, affecting the descaling effect on the liquid outlet hole 200 during the rotation of the movable member 30 relative to the front shell assembly 20. During the rotation of the movable member 30 relative to the front shell assembly 20, the annular structure 35 can rotate relative to the groove wall 601 and the connection portion 12 respectively.
