[0051] After the existing liquid discharge device is used, residual liquid is likely to form scale in the liquid discharge hole, blocking the liquid discharge hole and affecting the liquid discharge of the liquid discharge device.

[0052] The embodiments of the present application provide a liquid discharge device and a liquid discharge system. This liquid discharge system can be installed in various environments, such as companies, schools, homes, and factories, to clean items to be washed, thereby improving and enhancing people's quality of life and health. The liquid discharge device can be, but is not limited to, a faucet, a showerhead, or a spray gun. To facilitate the description of the technical solution of this application, the following description uses a showerhead as an example.

[0053] Please refer to Figures 1 to 8, Figures 13 to 15, Figure 19, Figure 20, Figure 23 and Figure 24 to describe the liquid discharge system provided in an embodiment of the present application. The liquid discharge system includes a liquid discharge device. Among them, the liquid discharge device includes a shell 10, a descaling component 20 and a surface shell mechanism 30. The descaling component 20 includes a plurality of descaling parts 21. The surface shell mechanism 30 and the shell 10 together form a water inlet chamber 100. The descaling component 20 is installed in the water inlet chamber 100 and is fixedly connected to the shell 10. The surface shell mechanism 30 is provided with a plurality of liquid discharge parts 3121, and each liquid discharge part 3121 is provided with at least one liquid discharge hole 200, and the liquid discharge hole 200 is connected to the water inlet chamber 100. In the embodiment of the present application, each liquid discharge part 3121 is provided with a plurality of liquid discharge holes 200. The aperture of the liquid discharge hole 200 is relatively small, and its diameter range is, for example, 0.2mm-0.8mm. This diameter range can make the liquid discharge softer. It is understood that in other embodiments, the diameter range of the liquid outlet hole 200 can also be other numerical ranges, so that the multiple liquid outlet holes 200 design of the liquid outlet portion 3121 can provide a softer liquid discharge compared to the single liquid outlet hole 200 design under the condition of the same liquid discharge volume. The diameters of the multiple liquid outlet holes 200 provided in each liquid outlet portion 3121 can be the same or different. The diameters of the liquid outlet holes 200 provided in different liquid outlet portions 3121 can be the same or different. In other embodiments, each liquid outlet portion 3121 can be provided with a single liquid outlet hole 200.

[0054] The multiple liquid outlets 3121 correspond one-to-one with the multiple scale removal components 21, i.e., one liquid outlet 3121 corresponds to one scale removal component 21. The housing mechanism 30 is movably mounted on the housing 10 and is configured to move toward the scale removal assembly 20, causing the scale removal components 21 to abut against the corresponding liquid outlets 3121. This abutment can drive the liquid outlets 3121 to vibrate or elastically deform, thereby removing scale deposited on the liquid outlets. The liquid outlets 3121 can be made of a hard material or an elastomeric material.

[0055] The liquid outlet system also includes a liquid inlet assembly. The housing 10 is provided with a connection portion for connection to the liquid inlet assembly. The connection portion can be connected to the liquid inlet assembly by, but is not limited to, threaded connection, plug-in connection, snap-on connection, or welding. The liquid inlet assembly is configured to supply liquid to the water inlet chamber 100. 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 outlet 200 from the liquid source. The liquid includes, but is not limited to, clean or purified water from the municipal water network.

[0056] The movement of the housing mechanism 30 toward the descaling assembly 20 reduces the volume of the water inlet chamber 100. When the liquid inlet assembly is opened, liquid enters the water inlet chamber 100, gradually pushing the housing mechanism 30 away from the descaling assembly 20, causing the housing mechanism 30 to reset under the action of liquid pressure, thereby facilitating multiple or repeated cleaning of the liquid outlet 200. Furthermore, in some exemplary embodiments, the housing mechanism 30 can be manually reset. The "pre-descaling" state in Figures 4, 7, 8, 14, 15, 20, and 24 refers to the reset state, and the "post-descaling" state refers to the descaling state.

[0057] In summary, the implementation of the embodiments of the present application will have the following beneficial effects: the liquid outlet device of the above-mentioned scheme is applied to the liquid outlet system. In addition to making the liquid outlet system have excellent cleaning performance, it can also perform descaling operations on the liquid outlet hole 200 to avoid scale and clogging of the liquid outlet hole 200. Specifically, the liquid outlet device includes a shell 10, a descaling component 20 and a surface shell mechanism 30. Among them, the descaling component 20 includes a plurality of descaling parts 21. The surface shell mechanism 30 and the shell 10 together form a water inlet chamber 100 in which the descaling component 20 can be installed. The surface shell mechanism 30 is provided with a plurality of liquid outlet parts 3121. The plurality of liquid outlet parts 3121 are provided with at least one liquid outlet hole 200 connected to the water inlet chamber 100 to facilitate liquid discharge from the liquid outlet device. The surface shell mechanism 30 is configured to be able to move toward the descaling component 20, so that the descaling component 21 abuts against the corresponding liquid outlet portion 3121, and utilizes the abutting action to drive the liquid outlet portion 3121 to vibrate (for example, the liquid outlet portion 3121 is made of a hard material or an elastomeric material) to shake off the scale, or utilizes the abutting action to drive the liquid outlet portion 3121 to produce elastic deformation (for example, the liquid outlet portion 3121 is made of an elastomeric material) to change the shape of the liquid outlet hole 200, so that the scale falls off.

[0058] In an exemplary embodiment, please refer to Figures 2, 4, 6 to 8, 11 to 21 and 23 to 25. The descaling assembly 20 also includes a frame 22, which is fixedly connected to the shell 10. Multiple descaling parts 21 are arranged on the frame 22, that is, multiple descaling parts 21 are arranged on the side of the frame 22 facing the surface shell mechanism 30, so that the multiple descaling parts 21 are connected to the shell 10 as a whole through the frame 22, so as to facilitate the rapid installation and installation accuracy of the multiple descaling parts 21.

[0059] The frame 22 is provided with a first guide portion 221. The face shell mechanism 30 includes a face shell assembly 31 and a connector 32. The connector 32 is fixedly connected to the face shell assembly 31, and a plurality of liquid outlets 3121 are provided on the face shell assembly 31. The connector 32 is provided with a second guide portion 321. The face shell assembly 31 moves toward the descaling assembly 20 through the guiding cooperation of the first guide portion 221 and the second guide portion 321, so that the descaling component 21 abuts against the corresponding liquid outlet 3121. In this way, through the guiding cooperation of the first guide portion 221 and the second guide portion 321, the accuracy of the movement of the face shell assembly 31 toward the descaling assembly 20 can be improved, thereby ensuring the cooperation accuracy of the descaling component 21 and the corresponding liquid outlet 3121.

[0060] In an exemplary embodiment, referring to Figures 3, 4, 7, 8, 11, 12, 14 to 18, 20, 21, 24, and 25, the first guide portion 221 can form a guide hole 300 in the frame 22. Specifically, the first guide portion 221 forms the wall of the guide hole 300, and the second guide portion 321 is a rod that extends through the guide hole 300 and cooperates with the first guide portion 221 for guidance. This avoids the need to provide the guide hole 300 in the face shell assembly 31, thereby reducing the strength of the face shell assembly 31. Furthermore, it avoids the need to provide a sealing structure for the water inlet chamber 100 in the face shell assembly 31. Forming the guide hole 300 in the frame 22 allows the second guide portion 321 to move within the water inlet chamber 100, eliminating the need to provide additional clearance for the second guide portion 321.

[0061] In an exemplary embodiment, referring to Figures 3, 4, 7, 8, 11, 14 to 16, 20, 21, 24, and 25, the second guide portion 321 is provided with a first clamping portion 3211, that is, the end of the second guide portion 321 facing the descaling assembly 20 is provided with the first clamping portion 3211. The first clamping portion 3211 is configured to cooperate with the frame 22 to drive the second guide portion 321 to undergo elastic deformation and pass through the guide hole 300. After the second guide portion 321 is reset, the first clamping portion 3211 cooperates with the frame 22 to limit the range of movement of the face shell assembly 31 away from the descaling assembly 20. In this way, the setting of the first clamping portion 3211 can achieve rapid assembly between the face shell mechanism 30 and the descaling component 20, improve assembly efficiency, and improve the connection stability between the face shell mechanism 30 and the descaling component 20, ensuring that the face shell mechanism 30 can always be connected to the descaling component 20 during the process of moving toward the descaling component 20 or away from the descaling component 20 under the action of liquid pressure, thereby ensuring the stability of descaling and the stability of resetting the face shell mechanism 30.

[0062] In this embodiment of the present application, the first engaging portion 3211 is a raised structure with an inclined surface. The inclined surface is capable of sliding along the frame 22 to gradually increase the elastic deformation of the second guide portion 321, allowing the second guide portion 321 to smoothly pass through the guide hole 300. Furthermore, the provision of the raised structure increases the area of ​​the first engaging portion 3211 facing the frame 22, thereby increasing the stability of the cover mechanism 30 in limiting movement away from the descaling assembly 20 and preventing separation of the cover mechanism 30 from the descaling assembly 20. The engaging portions in other embodiments described below may also have the same structure as the first engaging portion 3211 in this embodiment.

[0063] In an exemplary embodiment, please refer to Figures 3 to 5, 7, 8, 14, 15, 20 and 24. The face shell mechanism 30 also includes a first seal 33, which is sleeved on the face shell assembly 31 and clamped between the shell 10 and the face shell assembly 31 to achieve a sliding seal between the shell 10 and the face shell assembly 31. In this way, the provision of the first seal 33 can ensure the sealing between the face shell assembly 31 and the shell 10 during the movement of the face shell assembly 31 relative to the shell 10, and prevent liquid from flowing out from between the face shell assembly 31 and the shell 10. In the embodiment of the present application, the face shell assembly 31 is provided with an annular groove, and the first seal 33 is partially embedded in the annular groove to ensure the stability of the connection between the first seal 33 and the face shell assembly 31, and to prevent the first seal 33 from falling off during the movement of the face shell assembly 31 relative to the shell 10.

[0064] In an exemplary embodiment, referring to Figures 3 to 5, 7, 8, 10, 14, 15, 20, and 24, the face shell assembly 31 includes a body 311 and a liquid outlet 312. The body 311 is provided with a plurality of mounting holes 400. A plurality of liquid outlet portions 3121 are formed on the liquid outlet 312 and are mounted one-to-one in the plurality of mounting holes 400. The provision of the plurality of mounting holes 400 ensures that the positions of the plurality of liquid outlet portions 3121 are stable, thereby preventing the liquid outlet portions 3121 from being displaced relative to the body 311 under liquid impact, thereby affecting the liquid discharge effect.

[0065] The liquid outlet member 312 is clamped between the main body 311 and the connecting member 32 to further increase the connection stability between the liquid outlet member 312 and the main body 311, thereby further improving the position stability of the liquid outlet portion 3121. It can be understood that in other embodiments, the liquid outlet member 312 is configured to be connected to the main body 311 through a secondary injection molding process to ensure the connection stability of the liquid outlet member 312 and the main body 311. In this case, the connecting member 32 can be designed to be smaller in size to reduce the weight of the noodle shell mechanism 30, so that the noodle shell assembly 31 can move relative to the shell 10. In addition, in some embodiments, the liquid outlet portion 3121 and the liquid outlet member 312 can be integrally formed.

[0066] In an exemplary embodiment, please refer to Figures 4, 6, 7, 14, 15, 20 and 24, the liquid outlet 3121 can be enclosed into a groove 500, and the descaling component 21 can extend into the corresponding groove 500 and abut against the corresponding liquid outlet 3121. In this way, the provision of the groove 500 can play a certain guiding role for the descaling component 21, reducing the assembly precision requirements. In addition, the provision of the groove 500 enables the liquid outlet 312 to store a certain volume of liquid. Driven by the descaling component 21, the above-mentioned liquid can be discharged from the liquid outlet 200 at an increased pressure and speed, which has a certain impact on scaling and further improves the descaling effect.

[0067] In an exemplary embodiment, referring to Figures 2, 4, 7 to 9, and 12 to 15, the liquid outlet device further includes a reset member 40, which is clamped between the descaling assembly 20 and the housing mechanism 30. The reset member 40 is configured to drive the housing mechanism 30 to reset. The provision of the reset member 40 can further enhance the reset effect of the housing mechanism 30, and can achieve repeated descaling and reset operations without the action of liquid pressure. The descaling member 21 can repeatedly abut against the corresponding liquid outlet portion 3121, which is more conducive to the removal of scale and improves the descaling effect.

[0068] In an exemplary embodiment, please refer to Figures 2, 4, 13 to 15, the reset member 40 is a spring and is fixedly connected to at least one of the descaling assembly 20 and the surface shell mechanism 30 to improve the position stability of the reset member 40. In the embodiment of the present application, the surface shell mechanism 30 is provided with a connecting column 322, which is configured to be fixedly connected to the reset member 40. The reset member 40 can elastically abut the descaling assembly 20 or be fixedly connected to the descaling member 21. The reset member 40 is at least partially sleeved on the connecting column 322. The provision of the connecting column 322 can increase the connection area between the reset member 40 and the surface shell mechanism 30, improve the connection stability between the reset member 40 and the surface shell assembly 31, and prevent the reset member 40 from falling off during the movement of the surface shell assembly 31 relative to the shell 10. In addition, the setting of the connecting column 322 can also limit the range of movement of the surface shell mechanism 30 toward the descaling assembly 20, thereby preventing the surface shell mechanism 30 and the descaling assembly 20 from being too close, resulting in excessive abutment force of the descaling component 21 on the liquid outlet portion 3121, causing damage to the liquid outlet portion 3121 and cracks at the liquid outlet hole 200.

[0069] It can be understood that in other embodiments, the connecting column 322 can also be provided in the descaling assembly 20, and is configured to be fixedly connected to the reset member 40. In addition, the surface shell mechanism 30 and the descaling assembly 20 can both be provided with a connecting column 322, and the two connecting columns 322 are configured to be fixedly connected to the two ends of the reset member 40 respectively.

[0070] In an exemplary embodiment, please refer to Figures 8, 9 and 12, the reset member 40 includes an elastic arm 41, which is provided on one of the descaling assembly 20 and the housing mechanism 30, and can elastically abut against the other of the descaling assembly 20 and the housing mechanism 30. In this way, during the movement of the housing mechanism 30 toward the descaling assembly 20, the elastic arm 41 can gradually deviate from its original position and generate an elastic force to generate a driving force for driving the housing mechanism 30 to reset. In the embodiment of the present application, the elastic arm 41 is provided on the descaling assembly 20. It can be understood that in other embodiments, the elastic arm 41 can also be provided on the housing mechanism 30.

[0071] In an exemplary embodiment, please refer to Figures 7 to 9, 11 and 12, the elastic arm 41 is provided with a first positioning portion 42, and the other of the descaling assembly 20 and the shell mechanism 30 (i.e., the component abutted by the elastic arm 41) is provided with a second positioning portion 323. The first positioning portion 42 can be positioned and connected with the second positioning portion 323 and elastically abut against the second positioning portion 323. In this way, the elastic abutment position of the elastic arm 41 can be fixed by the provision of the first positioning portion 42 and the second positioning portion 323 to ensure the directional accuracy of the elastic force generated by the elastic arm 41, so that the elastic arm 41 can deviate from the original position and drive the shell mechanism 30 to reset in a preset manner, making the descaling process of the liquid outlet device and the reset process of the shell mechanism 30 smoother.

[0072] In an exemplary embodiment, referring to Figures 7 to 9, 11, and 12, one of the first positioning portion 42 and the second positioning portion 323 has a spherical cap 421, and the other has a notch portion 3231 that is positioned and connected to the spherical cap 421. The arrangement of the spherical cap 421 and the notch portion 3231 allows the relative positions of the first positioning portion 42 and the second positioning portion 323 to be automatically fine-tuned based on the actual direction of the elastic abutment force between the first positioning portion 42 and the second positioning portion 323, thereby avoiding stress concentration and improving the life of the reset member 40.

[0073] In the embodiment of the present application, the first positioning portion 42 is spherical, and the elastic arm 41 is disposed through the first positioning portion 42. The provision of the first positioning portion 42 can enhance the strength of the elastic arm 41, preventing breakage of the elastic arm 41 and increasing the elastic force that the elastic arm 41 can generate. Furthermore, the first positioning portion 42 has a portion facing the descaling assembly 20, which can limit the range of movement of the housing mechanism 30 toward the descaling assembly 20, preventing the housing mechanism 30 and the descaling assembly 20 from being too close together, which could result in excessive contact force between the descaling member 21 and the liquid outlet 3121, causing damage to the liquid outlet 3121 and cracks at the liquid outlet hole 200.

[0074] In one exemplary embodiment, the liquid outlet portion 3121 is configured to be made of an elastomeric material. As shown in Figures 4, 5, 7, 8, 15, 15, 20, and 24, the descaling member 21 abuts against the corresponding liquid outlet portion 3121, allowing the elastomeric liquid outlet portion 3121 to elastically deform, changing the shape of the liquid outlet hole 200 and removing scale. Furthermore, the elastomeric liquid outlet portion 3121 is relatively soft and is less likely to scratch or puncture the user during use.

[0075] It can be understood that in other embodiments, the liquid outlet portion 3121 can also be configured to be made of a hard material.

[0076] In an exemplary embodiment, referring to Figures 12 and 17 , the end of the descaling member 21 facing the liquid outlet 3121 includes a passivated surface 211 to reduce the impact of the descaling member 21 on the liquid outlet 3121, thereby reducing wear on the liquid outlet 3121 and preventing damage or rupture of the liquid outlet 3121. The liquid outlet 3121 is configured to be made of an elastomeric material. The liquid outlet 3121 can conform to the passivated surface 211 and deform to the shape of the passivated surface 211, making the deformation of the liquid outlet 200 more regular and further preventing the liquid outlet 3121 from tearing at the liquid outlet 200.

[0077] In an exemplary embodiment, referring to Figures 3 to 5, 7, and 8, the housing mechanism 30 is provided with a pressing portion 3111, that is, a pressing portion 3111 is provided on the side of the housing mechanism 30 away from the descaling assembly 20, so that the housing mechanism 30 can be driven toward the descaling assembly 20 by pressing the pressing portion 3111. In this way, by pressing the pressing portion 3111 with a finger, the housing mechanism 30 can be driven toward the descaling assembly 20 to achieve descaling, and the housing mechanism 30 can be reset under the action of liquid pressure and / or the reset member 40. The pressing portion 3111 can be provided at the outer edge of the housing mechanism 30 away from the descaling assembly 20 to facilitate the hand to drive the housing mechanism 30 with the housing 10 as the fulcrum.

[0078] In an exemplary embodiment, please refer to Figures 13 to 18 , the liquid outlet device also includes a pressing member 50 and a transmission member 60 . The pressing member 50 can be movably mounted on the shell 10 and exposed outside the shell 10 to facilitate fingers to press the pressing member 50 .

[0079] The transmission member 60 is disposed on the housing 10 or the descaling assembly 20. The pressing member 50 is configured to move relative to the housing 10, thereby driving the housing mechanism 30 toward the descaling assembly 20 via the transmission member 60. By configuring the pressing member 50 and the transmission member 60 in this manner, the driving force can be transmitted to the housing mechanism 30 via the transmission member 60 by pressing the pressing member 50, thereby driving the housing mechanism 30 toward the descaling assembly 20. This ensures more stable driving of the housing mechanism 30 and more uniform force applied to the housing mechanism 30.

[0080] In an exemplary embodiment, as shown in FIG15 , the transmission member 60 has a first end 61 abutting against the pressing member 50, a second end 62 abutting against the face shell assembly 31, and a hinge portion 63 located between the first end 61 and the second end 62, and the hinge portion 63 is hinged to the housing 10 or the descaling assembly 20. The pressing member 50 moves relative to the housing 10 to press the first end 61, and drives the face shell mechanism 30 to move toward the descaling assembly 20 through the second end 62. In this way, by providing a lever structure (transmission member 60) between the pressing member 50 and the face shell mechanism 30, the pressing member 50 and the face shell mechanism 30 can move toward each other in an ergonomic driving manner, thereby realizing the face shell mechanism 30 moving toward the descaling assembly 20 to perform the descaling operation. In the embodiment of the present application, the hinge portion 63 is hinged to the descaling assembly 20.

[0081] In an exemplary embodiment, referring to Figures 15 and 16 , the connecting member 32 is provided with a transmission groove 600, and the second end 62 is received in the transmission groove 600 to drive the housing mechanism 30 toward the descaling assembly 20, thereby improving the transmission stability between the transmission member 60 and the housing mechanism 30. The first end 61 can be disposed on the motion trajectory of the pressing member 50 to ensure the transmission stability between the pressing member 50 and the transmission member 60.

[0082] It can be understood that in other embodiments, both the pressing member 50 and the transmission member 60 are provided with racks, the driving force is transmitted between the two racks through gears, and the transmission member 60 is provided on the cover mechanism 30. The above arrangement can also realize the relative movement of the pressing member 50 and the cover mechanism 30 by pressing the pressing member 50.

[0083] In an exemplary embodiment, referring to Figures 15, 17, and 18, the housing 10 or the descaling assembly 20 is provided with a mounting groove 700, and the transmission member 60 is limitedly mounted in the mounting groove 700 to prevent the transmission member 60 from moving along its hinge axis. This improves the rotational stability of the transmission member 60, thereby ensuring the effective transmission of the driving force between the pressing member 50 and the cover mechanism 30. In this embodiment of the present application, the mounting groove 700 is located in the descaling assembly 20 and can pass through the descaling assembly 20, so as to facilitate the transmission member 60 to transmit the driving force between the pressing member 50 and the cover assembly 31.

[0084] In an exemplary embodiment, please refer to Figures 13 to 15 , the outer wall of the pressing member 50 is provided with a second sealing member 51, and the second sealing member 51 is clamped between the shell 10 and the pressing member 50 to achieve a sliding seal between the shell 10 and the pressing member 50. In this way, the provision of the second sealing member 51 can ensure the sealing between the pressing member 50 and the shell 10 during the movement of the pressing member 50 relative to the shell 10, and prevent liquid from flowing out from between the pressing member 50 and the shell 10. In the embodiment of the present application, the pressing member 50 is provided with an annular groove, and the second sealing member 51 is partially embedded in the annular groove to ensure the stability of the connection between the second sealing member 51 and the pressing member 50, and prevent the second sealing member 51 from falling off during the movement of the pressing member 50 relative to the shell 10.

[0085] In an exemplary embodiment, as shown in Figure 14, the pressing member 50 is provided with a first limiting portion 52 to prevent the pressing member 50 from separating from the housing 10. The first limiting portion 52 can be elastically deformed to achieve a snap connection between the pressing member 50 and the housing 10, thereby improving assembly efficiency.

[0086] In an exemplary embodiment, please refer to Figures 19 to 27, the liquid outlet device also includes a movable part 70, which can be movably mounted on the shell 10 and exposed to the shell 10 to facilitate finger-driven movement of the movable part 70. The movable part 70 is provided with a guide surface 71. The surface shell mechanism 30 is provided with a connecting arm 324, and the connecting arm 324 is slidably connected to the guide surface 71. The movable part 70 is configured to be able to move relative to the shell 10, so that the connecting arm 324 slides along the guide surface 71, thereby driving the surface shell mechanism 30 to move toward the descaling component 20. In this way, the movable part 70 moves relative to the shell 10 to facilitate driving the surface shell mechanism 30 to move toward the descaling component 20 to complete the descaling operation.

[0087] The motion is one of rotational motion, linear motion or curvilinear motion.

[0088] As shown in Figures 19 to 22, the movable member 70 rotates. The corresponding guide surface 71 is spiral. By driving the movable member 70 to rotate relative to the housing 10, the connecting arm 324 slides along the guide surface 71, thereby driving the housing mechanism 30 toward the descaling assembly 20. In this embodiment, the movable member 70 is a knob structure.

[0089] As shown in Figures 23 to 27 , the movable member 70 moves linearly. The corresponding guide surface 71 is inclined. By driving the movable member 70 in linear motion relative to the housing 10, the connecting arm 324 slides along the guide surface 71, thereby driving the housing mechanism 30 toward the descaling assembly 20. In this embodiment, the movable member 70 is a push button structure.

[0090] In an exemplary embodiment, referring to FIG. 21 , FIG. 22 , FIG. 25 and FIG. 26 , the connecting arm 324 is snap-fitted to the movable member 70 , so that the connecting arm 324 and the movable member 70 can be quickly connected by snap-fitting.

[0091] As shown in Figures 21 and 22, the rotatable movable member 70 has a circumferential wall 75, and the corresponding housing mechanism 30 is provided with a plurality of connecting arms 324. The circumferential wall 75 can enclose a plug-in slot and define a plurality of engaging slots 800. The engaging slots 800 correspond one-to-one with the plurality of connecting arms 324. The connecting arms 324 have second engaging portions 3241. The second engaging portions 3241 are configured to cooperate with the circumferential wall 75 to elastically deform the connecting arms 324 and extend into the plug-in slot. The second engaging portions 3241 face the engaging slots 800 and extend into the engaging slots 800. At this point, the connecting arms 324 return to their original position to prevent the second engaging portions 3241 from disengaging from the engaging slots 800. The engaging slots 800 can form guide surfaces 71 on the circumferential wall 75, along which the second engaging portions 3241 can slide.

[0092] As shown in Figures 25 and 26, the movable member 70 capable of linear motion has two oppositely disposed clamping arms 72, each of which is provided with a third clamping portion 721. The two third clamping portions 721 are disposed opposite each other. The guide surface 71 is located on the third clamping portion 721. The connecting arm 324 has a fourth clamping portion 3242, which can drive the two clamping arms 72 to open via the third clamping portion 721. After the fourth clamping portion 3242 passes over the third clamping portion 721, the clamping arm 72 is reset, so that the fourth clamping portion 3242 can be accommodated between the two clamping arms 72 and can slide along the guide surface 71. This embodiment is illustrated by taking the movable member 70 as an example in which it includes two clamping arms 72. In other examples, the movable member 70 can include more clamping arms 72.

In this way, the provision of the third sealing member 73 can ensure the sealing between the movable part 70 and the shell 10 during the movement of the movable part 70 relative to the shell 10, and prevent liquid from flowing out from between the movable part 70 and the shell 10. In the embodiment of the present application, the movable part 70 is provided with an annular groove, and the third sealing member 73 is partially embedded in the annular groove to ensure the connection stability between the third sealing member 73 and the movable part 70, and prevent the third sealing member 73 from falling off during the movement of the movable part 70 relative to the shell 10. And / or

[0094] Referring to Figures 23 and 24 , a fourth seal 74 is provided between the descaling assembly 20 and the connecting arm 324. The fourth seal 74 is clamped between the descaling assembly 20 and the connecting arm 324 to provide a sliding seal between the descaling assembly 20 and the connecting arm 324. The provision of the fourth seal 74 ensures a tight seal between the connecting arm 324 and the descaling assembly 20 during movement of the connecting arm 324 relative to the descaling assembly 20, preventing liquid from flowing from between the connecting arm 324 and the descaling assembly 20 to the movable member 70 and out from between the movable member 70 and the housing 10. In this embodiment of the present application, the connecting arm 324 is provided with an annular groove, and the fourth seal 74 is partially embedded in the annular groove to ensure a stable connection between the fourth seal 74 and the connecting arm 324 and prevent the fourth seal 74 from falling off during movement of the connecting arm 324 relative to the descaling assembly 20.
