[0007] In some embodiments of the liquid outlet device, the multiple elastic protrusions of the first deformation portion and the multiple elastic protrusions of the second deformation portion are integrally formed in a one-to-one correspondence, and extend along the extension direction of the liquid outlet hole to the liquid outlet end of the liquid outlet hole.

[0008] In some embodiments of the liquid outlet device, grooves are provided between adjacent elastic protrusions, and the grooves separate adjacent elastic protrusions; The bottom of the groove is an arc surface and protrudes toward a side away from the flow space.

[0009] In some embodiments of the liquid outlet device, the first deformation portion includes an annular elastic portion, which can partially cover the liquid outlet hole, the circumferential outer side of the annular elastic portion is arranged on the surface shell assembly, and the circumferential inner side of the annular elastic portion surrounds the flow space.

[0010] In some embodiments of the liquid outlet device, the annular elastic portion is provided with an annular groove surrounding the flow space, and the annular groove has a notch facing the liquid outlet end of the liquid outlet hole.

[0011] In some embodiments of the liquid outlet device, the annular elastic portion includes a first annular wall and a second annular wall, and the first annular wall includes a first end and a second end; The first end is disposed on the main body, and one end of the second annular wall is disposed on the second end and is bent from the second end to the first end to form the annular groove.

[0012] In some embodiments of the liquid outlet device, a side of the first annular wall facing away from the annular groove is spaced apart from the surface shell assembly.

[0013] In some embodiments of the liquid outlet device, the annular elastic portion is arranged close to the liquid inlet end of the liquid outlet hole, and in the liquid-cutting and descaling posture: the circumferential outer side of the descaling component contacts the annular elastic portion to make the target flow area zero.

[0023] The disclosed embodiment provides a ceiling showerhead, which can be installed in various environments such as companies, schools, homes, and factories to clean the body, thereby improving and enhancing people's quality of life and health.

[0024] Please combine Figure 1 , Figure 2 , Figures 4 to 14 The top shower provided by the embodiment of the present disclosure is now described. The top shower comprises a liquid outlet device and a reset member 40 .

[0025] The liquid outlet device includes a main body and a descaling assembly 20. The main body has a mounting cavity 100 formed in the main body and a surface shell assembly 30 having a plurality of liquid outlet holes 300. The liquid outlet holes 300 are connected to the mounting cavity 100. The main body also includes a shell assembly 10. The shell assembly 10 and the surface shell assembly 30 can be integrally formed or separately arranged. The surface shell assembly 30 and the shell assembly 10 enclose the mounting cavity 100.

[0026] The descaling assembly 20 is installed in the installation cavity 100, and includes a plurality of descaling parts 21 corresponding to the plurality of liquid outlets 300. The descaling assembly 20 has a liquid-passing posture for allowing the descaling part 21 to be separated from the liquid outlet 300 so that the liquid outlet 300 passes through the liquid, and a liquid-stopping descaling posture for allowing the descaling part 21 to be reinserted into the liquid outlet 300 for descaling. In the liquid-passing posture, the descaling assembly 20 and the surface shell assembly 30 move away from each other until the relative positions are fixed. In the liquid-stopping descaling posture, the descaling assembly 20 and the surface shell assembly 30 move closer to each other until the relative positions are fixed.

[0027] The liquid outlet 300 is provided with a first deformation part and a liquid passing part connected to the face shell assembly 30, the first deformation part surrounds and forms a flow space 301 connected to the liquid passing part, in the liquid-cutting and descaling posture: the first deformation part is arranged to contact with the descaling component 21 to reduce the flow area entering the flow space 301 to the target flow area, and is arranged to deform under the applied force of the descaling component 21 to allow the descaling component 21 to move relative to the liquid passing part downstream of the first deformation part for descaling. Among them, the target flow area is the flow area after the descaling component 21 contacts with the first deformation part and blocks the flow space 301.

[0028] In the embodiment of the present disclosure, the descaling assembly 20 is in the liquid-cutting descaling posture of allowing the descaling member 21 to be reinserted into the liquid outlet 300 for descaling: the first deformable portion is configured to contact the descaling member 21 (at this time, the first deformable portion does not produce compression deformation) to reduce the flow area entering the flow space 301 to the target flow area, thereby greatly reducing the flow area of ​​the flow space 301 to intercept most of the liquid entering the flow space 301. The first deformable portion is configured to deform under the applied force of the descaling member 21 to allow the descaling member 21 to move relative to the liquid flow portion downstream of the first deformable portion for descaling. In this way, in the process of the descaling member 21 continuing to be inserted into the liquid outlet 300, it further fits with the first deformable portion to compress the first deformable portion, and the deformation of the first deformable portion makes the fit between the descaling member 21 and the first deformable portion tighter, so that the liquid entering the flow space 301 can be intercepted before the descaling member 21 moves relative to the liquid flow portion for descaling, achieving a higher efficiency of immediate stop. During the descaling operation of the descaling member 21 moving relative to the liquid passing portion, the descaling member 21 can further compress the first deformation portion to cut off the liquid in advance, and can also make the descaling member 21 move relative to the liquid passing portion to achieve the descaling function until the relative positions of the descaling component 20 and the surface shell component 30 are fixed, and the descaling operation is completed.

[0029] One of the descaling component 20 and the surface shell component 30 can be movably mounted on the shell component 10. The reset member 40 is connected to at least one of the descaling component 20 and the surface shell component 30. The reset member 40 is configured to generate a driving force to drive the descaling component 20 and the surface shell component 30 to approach each other, so that the descaling component 20 is in the liquid-cut-off descaling posture. Driven by the reset member 40, a plurality of descaling components 21 are arranged one by one through the flow space 301, and gradually compress the corresponding first deformation portion until the relative position of the descaling component 20 and the surface shell component 30 is fixed. In addition, in some embodiments, driving the descaling component 20 and the surface shell component 30 to approach each other can also be achieved by manual drive or under the action of gravity.

[0030] At least one of the descaling assembly 20 and the housing assembly 30 is configured to be driven by an external force to overcome the driving force, separate the descaling member 21 from the corresponding first deformable portion, and restore the first deformable portion to its original state, and the descaling assembly 20 is in a liquid-passing state. The liquid includes but is not limited to clean water or pure water from a municipal water network. The external force can be generated by a mechanical structure or by a liquid.

[0031] When the liquid supply to the liquid outlet device stops, under the action of the driving force, the descaling component 21 and the liquid outlet hole 300 approach each other and perform the descaling operation. The descaling component 21 first fits with the first deformation part (at this time, the first deformation part does not produce compression deformation) to form an interference fit, thereby reducing the flow area of ​​the flow space 301 and achieving instant stop. After that, the descaling component 21 continues to perform the descaling operation and compresses the first deformation part to further improve the tightness of the fit between the descaling component 21 and the first deformation part. If the descaling operation is not completely completed, the liquid entering the flow space 301 is intercepted, achieving a higher efficiency of instant stop. The descaling component 21 can further compress the first deformation part until the relative positions of the descaling component 20 and the surface shell component 30 are fixed, and the descaling operation is completed. During the above process, the descaling component 21 can gradually fill the liquid outlet 300 , and while completing the descaling, it can drain the residual liquid in the liquid outlet 300 , thereby preventing the residual liquid in the liquid outlet 300 from being discharged during subsequent use and affecting the user experience.

[0032] In the disclosed embodiment, the descaling assembly 20 can separate the installation cavity 100 into a liquid inlet cavity 200 located between the descaling assembly 20 and the surface shell assembly 30, and a plurality of liquid outlet holes 300 are connected to the liquid inlet cavity 200. The external force is the driving force of the liquid entering the liquid inlet cavity 200 acting on at least one of the descaling assembly 20 and the surface shell assembly 30.

[0033] The surface shell assembly 30 is fixedly connected to the shell assembly 10. The descaling assembly 20 can be movably mounted on the shell assembly 10. When liquid is supplied to the liquid outlet device, the liquid entering the liquid inlet chamber 200 can drive the descaling assembly 20, so that the descaling assembly 20 can overcome the driving force generated by the reset member 40 and move relative to the mounting chamber 100, separate the descaling member 21 from the corresponding first deformation portion, and the descaling assembly 20 is in a liquid-passing posture. At this time, the flow space 301 is open, and can be connected to the liquid inlet chamber 200 directly or through the liquid outlet hole 300, so that the liquid can be discharged from the liquid outlet device from the flow space 301. When the liquid supply to the liquid outlet device is stopped, the driving force of the reset member 40 overcomes the driving force of the liquid on the descaling assembly 20, so that the multiple descaling members 21 are arranged one by one through the flow space 301, and the corresponding first deformation portion is compressed, and the descaling assembly 20 is in a liquid-cutting descaling posture.

[0034] Among them, in the embodiment of the present disclosure, the reset member 40 is a spring, and is clamped between the side of the descaling component 20 facing away from the surface shell component 30 and the shell component 10, so as to provide a driving force to maintain the multiple descaling components 21 to pass through the flow space 301 in a one-to-one correspondence. In addition, in other embodiments, the reset member 40 may also include a first magnetic attraction portion and a second magnetic attraction portion, the first magnetic attraction portion is arranged on the descaling component 20, and the second magnetic attraction portion is arranged on the surface shell component 30. The descaling component 20 can move toward the surface shell component 30 through the magnetic attraction force formed between the first magnetic attraction portion and the second magnetic attraction portion, so that the multiple descaling components 21 pass through the flow space 301 in a one-to-one correspondence, and compress the corresponding first deformation portion.

[0035] It can be understood that in other embodiments, the face shell assembly 30 can also be movably mounted on the shell assembly 10. The descaling assembly 20 is fixedly connected to the shell assembly 10. When liquid is supplied to the liquid outlet device, the liquid entering the liquid inlet chamber 200 can drive the face shell assembly 30, so that the face shell assembly 30 can overcome the driving force generated by the reset member 40 and move relative to the shell assembly 10, separate the descaling member 21 from the corresponding first deformation portion, and the descaling assembly 20 is in a liquid-passing posture. At this time, the flow space 301 is open and can be connected to the liquid inlet chamber 200 directly or through the liquid outlet hole 300, so that the liquid can be discharged from the liquid outlet device from the flow space 301. When the liquid supply to the liquid outlet device is stopped, the driving force of the reset member 40 overcomes the driving force of the liquid on the face shell assembly 30, so that the multiple descaling members 21 are arranged one by one through the flow space 301, and the corresponding first deformation portion is compressed, and the descaling assembly 20 is in a liquid-cutting and descaling posture.

[0036] The reset member 40 may be a spring and clamped between the side of the face shell assembly 30 away from the descaling assembly 20 and the shell assembly 10 to provide a driving force to maintain the multiple descaling members 21 correspondingly passing through the flow space 301. In addition, in other embodiments, the reset member 40 may also include a first magnetic attraction portion and a second magnetic attraction portion, the first magnetic attraction portion being arranged on the descaling assembly 20, and the second magnetic attraction portion being arranged on the face shell assembly 30. The face shell assembly 30 may move toward the descaling assembly 20 through the magnetic attraction force formed between the first magnetic attraction portion and the second magnetic attraction portion, so that the multiple descaling members 21 pass through the flow space 301 correspondingly one by one, and the corresponding first deformation portion is compressed.

The flow guide 121 is provided with a through hole 203 connected to the escape space 500 and the flow channel 202.

[0048] In the exemplary embodiment, please combine Figures 9 to 12 The first deformation part includes a plurality of elastic protrusions 61, which surround the liquid outlet 300 and are arranged at intervals on the side facing the flow space 301. In this way, when the descaling member 21 is in contact with the elastic protrusions 61, the liquid can only flow through the gaps between adjacent elastic protrusions 61, thereby reducing the flow area of ​​the flow space 301. The plurality of elastic protrusions 61 are arranged at intervals on the side facing the flow space 301, so that the side of the elastic protrusions 61 facing the flow space 301 has a larger deformation space, and then under the drive of the descaling member 21, the gaps between adjacent elastic protrusions 61 can be gradually filled through compression deformation until the adjacent elastic protrusions 61 are completely in contact, thereby stopping the liquid entering the flow space 301. The multiple elastic protrusions 61 are arranged at intervals on the side facing the flow space 301, and the deformation of the side of the elastic protrusion 61 facing the flow space 301 is not affected by the adjacent elastic protrusions 61. As a result, the multiple elastic protrusions 61 can be gradually deformed synchronously on both sides of the circumference of the descaling component 21 during compression by the descaling component 21, so that the reduction amplitude of the gap between each adjacent elastic protrusion 61 is synchronized until each gap is completely filled by the elastic protrusion 61, thereby avoiding that after the descaling operation of the descaling component 21 is completed, there are still gaps that are not completely filled, affecting the liquid cutoff effect.

[0049] The elastic protrusions 61 are configured to deform around the two circumferential sides of the descaling member 21 under the force applied by the descaling member 21 to reduce the gap between adjacent elastic protrusions 61. This can further improve the fit between the descaling member 21 and the first deformable portion, ensuring the liquid interception effect.

[0050] In an exemplary embodiment, please continue to refer to Figures 9 to 12, the liquid passing part has a second deformation part, the second deformation part includes a plurality of elastic protrusions 61, the plurality of elastic protrusions 61 surround the liquid outlet 300, and the plurality of elastic protrusions 61 are arranged at intervals on the side facing the flow space 301. In this way, the descaling member 21 can fit with the elastic protrusions 61 when it moves relative to the liquid passing part, and the liquid can only flow through the gaps between adjacent elastic protrusions 61, thereby reducing the flow area of ​​the flow space 301. The plurality of elastic protrusions 61 are arranged at intervals on the side facing the flow space 301, so that the side of the elastic protrusions 61 facing the flow space 301 has a larger deformation space, and then under the drive of the descaling member 21, the gaps between adjacent elastic protrusions 61 can be gradually filled by compression deformation until the adjacent elastic protrusions 61 are completely fitted, and the liquid entering the flow space 301 is intercepted. The multiple elastic protrusions 61 are arranged at intervals on the side facing the flow space 301, and the deformation of the side of the elastic protrusion 61 facing the flow space 301 is not affected by the adjacent elastic protrusions 61. As a result, the multiple elastic protrusions 61 can be gradually deformed synchronously on both sides of the circumference of the descaling component 21 during compression by the descaling component 21, so that the reduction amplitude of the gap between each adjacent elastic protrusion 61 is synchronized until each gap is completely filled by the elastic protrusion 61, thereby avoiding that after the descaling operation of the descaling component 21 is completed, there are still gaps that are not completely filled, affecting the liquid cutoff effect.

[0051] The multiple elastic protrusions 61 of the first deformation part and the multiple elastic protrusions 61 of the second deformation part can both extend in the extension direction of the liquid outlet hole 300. The multiple elastic protrusions 61 of the first deformation part and the multiple elastic protrusions 61 of the second deformation part can be staggered along the extension direction of the liquid outlet hole 300. The multiple elastic protrusions 61 of the first deformation part and the multiple elastic protrusions 61 of the second deformation part can also be integrally formed in a one-to-one correspondence, extending along the extension direction of the liquid outlet hole 300 to the liquid outlet end of the liquid outlet hole 300. In this way, the descaling part 21 can have a larger area in contact with the elastic protrusions 61 along its descaling movement direction (the axial direction of the descaling part 21), thereby improving the stability of the instant stop and turn-off function.

[0052] Furthermore, the multiple elastic protrusions 61 of the first deformation part and the multiple elastic protrusions 61 of the second deformation part are integrally formed in a one-to-one correspondence, so that when the flow space 301 is in an open state, the gap between adjacent elastic protrusions 61 can extend to the liquid outlet end of the liquid outlet hole 300, which plays a guiding role for the liquid, making the shape of the liquid outlet pattern of the liquid outlet device more stable. The end of the elastic protrusion 61 close to the liquid inlet end of the liquid outlet hole 300 can also extend to the liquid inlet end of the liquid outlet hole 300 or be spaced from the liquid inlet end of the liquid outlet hole 300.

[0053] In the disclosed embodiment, the side of the elastic protrusion 61 facing the flow space 301 can be gradually narrowed to form an edge 611, thereby improving the guiding effect on the liquid.

[0054] In an exemplary embodiment, Fig. 9 As shown, a groove 600 is provided between adjacent elastic protrusions 61, and the groove 600 separates and sets adjacent elastic protrusions 61. The groove bottom 612 of the groove 600 is in an arc shape and protrudes toward the side away from the flow space 301. In this way, by setting the above groove 600, the risk of stress concentration between adjacent elastic protrusions 61 can be reduced during the deformation of the elastic protrusion 61, and cracks between adjacent elastic protrusions 61 can be avoided, which affects the service life. In addition, the above groove 600 can further enhance the guiding effect on the liquid.

[0055] In the exemplary embodiment, please combine Figure 3 and Figures 11 to 14 The descaling member 21 is conical, including a small end 211 close to the liquid outlet 300 and a large end 212 away from the liquid outlet 300. In this way, the descaling member 21 can be conveniently inserted into the flow space 301, and the descaling member 21 fits with the elastic protrusion 61, and the descaling member 21 is convenient to move relative to the elastic protrusion 61, completing the descaling operation and separating from the elastic protrusion 61.

[0056] The liquid outlet hole 300 is conical, and the radial dimension of the liquid inlet end of the liquid outlet hole 300 is larger than the dimension of the liquid outlet end of the liquid outlet hole 300. In this way, the liquid outlet hole 300 can be gradually narrowed, thereby increasing the liquid discharge speed and thus improving the liquid discharge effect. Among them, the narrowing range of the descaling component 21 and the liquid outlet hole 300 can be roughly the same or different.

[0057] In the exemplary embodiment, please combine Fig.13 and Fig.14 The first deformation portion includes an annular elastic portion 62, which can partially cover the liquid outlet 300, and the circumferential outer side of the annular elastic portion 62 is arranged on the surface shell assembly 30. The circumferential inner side of the annular elastic portion 62 surrounds the flow space 301. In this way, when the descaling assembly 20 is in the liquid-cutting descaling posture, the descaling member 21 can be inserted into the annular elastic portion 62 and fit with the annular elastic portion 62. The liquid can only pass between the descaling member 21 and the annular elastic portion 62 by driving the annular elastic portion 62 to deform, thereby reducing the flow area of ​​the flow space 301. When the descaling component 21 continues to perform the descaling operation, the annular elastic portion 62 is deformed under the force applied by the descaling component 21, so that the descaling component 21 can provide support to the side of the annular elastic portion 62 away from the surface shell assembly 30, so as to prevent the annular elastic portion 62 from deforming under the drive of the liquid, resulting in a gap for liquid to pass between the descaling component 21 and the annular elastic portion 62, thereby making the flow space 301 unable to be sealed.

[0058] In an exemplary embodiment, please continue to refer to Fig.13 and Fig.14The annular elastic part 62 is provided with an annular groove 700 surrounding the flow space 301, and the annular groove 700 has a notch facing the liquid outlet end of the liquid outlet hole 300. The provision of the annular groove 700 can improve the elastic deformation ability of the annular elastic part 62 and improve the fitting stability between the annular elastic part 62 and the descaling member 21. The provision of the annular groove 700 also makes the deformation of the annular elastic part 62 as a whole driven by the descaling member 21 synchronous and have approximately the same degree of compression, ensuring that the compression and restoration of the annular elastic part 62 are smoother.

[0059] The notch faces the liquid outlet end of the liquid outlet hole 300, which can prevent the liquid from entering the annular groove 700 when passing through the flow space 301, thereby affecting the smooth passage of the liquid through the flow space 301. In addition, by preventing the liquid from entering the annular groove 700 when passing through the flow space 301, the area of ​​the annular elastic part 62 acting on the liquid can be reduced, thereby preventing the annular elastic part 62 from being greatly deformed under the drive of the liquid, thereby affecting the sealing of the flow space 301 by the descaling member 21 and the annular elastic part 62.

[0060] In an exemplary embodiment, please continue to refer to Fig.13 and Fig.14 The annular elastic portion 62 includes a first annular wall 621 and a second annular wall 622 , and the first annular wall 621 includes a first end 6211 and a second end 6212 .

[0061] The first end 6211 is arranged on the face shell assembly 30, and one end of the second annular wall 622 is arranged on the second end 6212, and is bent from the second end 6212 to the first end 6211 to form an annular groove 700, so that the cross-section of the annular elastic portion 62 taken along its axial direction is an inverted V-shape, so that the flow space 301 is in an open state, and the liquid can be guided by the second annular wall 622 to be more comfortably introduced into the flow space 301; under the drive of the descaling component 21, the annular elastic portion 62 is easier to deform, and the elastic force generated makes the second annular wall 622 fit more stably with the descaling component 21.

[0062] In an exemplary embodiment, please continue to refer to Fig.13 and Fig.14 , the side of the first annular wall 621 away from the annular groove 700 is spaced from the face shell assembly 30. In the embodiment of the present disclosure, the side of the first annular wall 621 away from the annular groove 700 is spaced from the face shell assembly 30. In this way, the elastic deformation ability of the first annular wall 621 can be improved, the movement range of the second end 6212 can be improved, and the movement range of the second annular wall 622 driven by the descaling member 21 can be increased, so as to avoid the descaling member 21 moving relatively smoothly relative to the second annular wall 622 and destroying the inverted V-shaped structure of the annular elastic part 62. The side of the first annular wall 621 away from the annular groove 700 is spaced from the face shell assembly 30 to form a spacing groove 800.

[0063] In an exemplary embodiment, please continue to refer to Fig.13 and Fig.14 , the annular elastic part 62 is arranged near the liquid inlet end of the liquid outlet hole 300, that is, the annular elastic part 62 is arranged on the side of the face shell assembly 30 facing the installation cavity 100. In the liquid-cutting and descaling posture: the circumferential outer side of the descaling member 21 contacts the annular elastic part 62 so that the target flow area is 0. At this time, the flow space 301 can be sealed without completely completing the descaling operation, so as to achieve a higher efficiency of immediate shutdown.

[0064] The descaling member 21 has an arc surface 213 on the circumferential outer side. When the descaling member 21 penetrates the flow space 301 corresponding to the seal, the arc surface 213 can fit with the side of the second annular wall 622 away from the annular groove 700. In this way, the arrangement of the arc surface 213 can increase the fitting surface area between the second annular wall 622 and the descaling member 21, thereby improving the fitting stability. In addition, the arrangement of the arc surface 213 can also maintain the relative stability of the inverted V-shaped structure of the annular elastic part 62, so that the second annular wall 622 can be bent in a preset direction, thereby improving the life of the annular elastic part 62.

[0065] The first deformation portion may include a plurality of elastic protrusions 61 or an annular elastic portion 62. It can be understood that in other embodiments, the first deformation portion may also include a plurality of elastic protrusions 61 and an annular elastic portion 62.
