[0058] In areas with poor water quality, the water outlet device is prone to scaling, affecting the user experience and, in severe cases, causing the water outlet device to fail. To address the above issues, the water channel structure of the water outlet device is often equipped with a scale-inhibiting structure to prevent scale formation.

[0059] After a period of use, the scale-inhibiting structure needs to be replaced to ensure its effectiveness in preventing scale formation. However, replacing the scale-inhibiting structure requires destroying the original waterway structure, which requires certain assembly skills to replace and restore the scale-inhibiting structure, causing inconvenience to the user.

[0060] The disclosed embodiment provides a scale prevention mechanism and a water outlet device, which can be installed in various environments such as companies, schools, homes, and factories to achieve cleaning of items to be cleaned and body parts, thereby improving and improving people's quality of life and health.

[0061] Please combine Figures 1 to 5 、 Figure 7 and Figure 10 The water outlet device provided by the embodiment of the present disclosure is now described. The water outlet device includes a water outlet body 10 and a scale prevention mechanism 20. The water outlet body 10 is provided with a water channel structure. The water channel structure includes a water inlet connector 30, a water inlet valve 40, and a water diversion valve 50.

[0062] The scale inhibitor mechanism 20 is arranged on the water outlet body 10. The scale inhibitor mechanism 20 includes a valve body 21, a water stop valve 22 and a scale inhibitor core assembly 23. The valve body 21 is provided with a water inlet 100, a water outlet 200 and an installation cavity 300. The installation cavity 300 communicates between the water inlet 100 and the water outlet 200. The valve body 21 is further provided with an installation hole 400, and the installation hole 400 communicates with the installation cavity 300. The water stop valve 22 is installed at the water inlet 100 and can disconnect the water inlet 100 and the installation cavity 300. The scale inhibitor core assembly 23 is detachably connected to the valve body 21. The scale inhibitor core assembly 23 is arranged to be installed in the installation cavity 300 through the installation hole 400, and is located between the water inlet 100 and the water outlet 200, and can drive the water stop valve 22 to communicate the water inlet 100 and the installation cavity 300; the scale inhibitor core assembly 23 is further arranged to be removed from the installation cavity 300 through the installation hole 400 and separated from the water stop valve 22, so that the water stop valve 22 is reset. The water inlet 100 and the water outlet 200 are respectively communicated with the water path structure.

[0063] In the embodiment of the present disclosure, the water inlet valve 40 is communicated between the water inlet joint 30 and the water inlet 100. The water inlet valve 40 is arranged to be able to control the water flow rate entering the water inlet 100 from the water inlet joint 30. The number of the water inlet joints 30 can be one or more. For example, the number of the water inlet joints 30 can be two, which are respectively communicated with a hot water source and a cold water source. The water inlet valve 40 is further arranged to be able to control the communication area between the two water inlet joints 30 and the water inlet 100 to control the water temperature entering the water inlet 100. The water outlet device can further include a plurality of water outlet mechanisms. The water outlet mechanism can be, but is not limited to, a water outlet faucet, a shower head, a ceiling spray or a spray gun. The water outlet 200 can be communicated with a plurality of water outlet mechanisms through a water distribution valve 50. After the water enters the water inlet 100, it can be scale-inhibited by the scale inhibitor core assembly 23 located between the water inlet 100 and the water outlet 200, and is discharged into the water distribution valve 50 from the water outlet 200. The user can control the water distribution valve 50 to introduce the water into different water outlet mechanisms and discharge it.

[0064] The installation hole 400 is exposed outside the water outlet body 10. In the embodiment of the present disclosure, the water outlet body 10 is provided with an avoidance hole 500, so that the installation hole 400 can be exposed outside the water outlet body 10, which is convenient for replacing the scale inhibitor core assembly 23. In addition, most of the structures of the scale inhibitor mechanism 20 and most of the structures of the water path structure are located inside the water outlet body 10, and the connection positions of the water inlet 100 and the water outlet 200 with the water path structure are both located inside the water outlet body 10, so that the overall beauty of the water outlet device can be ensured.

[0065] In summary, implementing the embodiments of the present disclosure will have the following beneficial effects: The scale inhibitor mechanism 20 of the above solution is applied and equipped in the water outlet device. In addition to enabling the water outlet device to have excellent scale inhibition performance, it can also not damage the original water circuit structure during the process of replacing the scale inhibition structure, facilitating the user to replace the scale inhibition structure. Specifically, the scale inhibitor mechanism 20 includes a valve body 21 provided with a water inlet 100, a water outlet 200, a mounting hole 400, and a mounting cavity 300, a water stop valve 22 installed at the water inlet 100, and a scale inhibitor core assembly 23 (scale inhibition structure) detachably connected to the valve body 21. Among them, the mounting cavity 300 communicates between the water inlet 100 and the water outlet 200. The water inlet 100 and the water outlet 200 are respectively communicated with the water circuit structure of the water outlet device, so that water can enter the water inlet 100 through the water circuit structure and be discharged from the water outlet 200. The mounting hole 400 is independently arranged relative to the water inlet 100 and the water outlet 200, avoiding damage to the original connection relationship between the water inlet 100 and the water outlet 200 and the water circuit structure during the process of installing the scale inhibitor core assembly 23 into the mounting cavity 300 or removing it from the mounting cavity 300, and the mounting hole 400 can be exposed on the outer surface of the water outlet device, thus facilitating the user to replace the scale inhibitor core assembly 23. The scale inhibitor core assembly 23 installed in the mounting cavity 300 can drive the water stop valve 22 to communicate the water inlet 100 with the mounting cavity 300, so that water can be discharged from the water outlet 200 after being scale-inhibited through the scale inhibitor core assembly 23. The water stop valve 22 can also reset after being separated from the scale inhibitor core assembly 23 to disconnect the water inlet 100 and the mounting cavity 300, avoiding water entering the mounting cavity 300 and flowing out from the mounting hole 400 during the process of replacing the scale inhibitor core assembly 23, which brings inconvenience to the replacement of the scale inhibitor mechanism 20.

[0066] In an exemplary embodiment, please also combine Figure 5 , Figure 7 , Figure 10 , Figure 12 and Figure 14 , the scale inhibitor core assembly 23 includes a core shell 231. The core shell 231 has a water inlet end 501 and a water outlet end 502. The water inlet end 501 is communicated with the water inlet 100, and the water outlet end 502 is communicated with the water outlet 200. The core shell 231 also has a receiving cavity 503. The receiving cavity 503 communicates between the water inlet end 501 and the water outlet end 502, and a scale inhibitor unit 232 is accommodated in the receiving cavity 503. In this way, through the setting of the core shell 231, the scale inhibitor unit 232 can have a relatively stable working environment to ensure the stability of the operation of the scale inhibitor unit 232. Moreover, by using the water inlet end 501 and the water outlet end 502 provided on the core shell 231, the water has a certain flow direction, ensuring that the water can effectively contact the scale inhibitor unit 232 and improving the scale inhibition effect.

[0067] In an exemplary embodiment, the material of the scale inhibitor unit 232 is a scale inhibitor alloy or polyphosphate. Among them, the scale inhibitor alloy can release free electrons into the water flowing through the scale inhibitor unit 232. The free electrons can combine with the free calcium ions and magnesium ions in the water to prevent the free calcium ions and magnesium ions from combining with carbonate ions to form scale (scale prevention); moreover, the scale inhibitor alloy can also change the crystal structure of scale such as calcium carbonate, making it change from a hard marble structure to a soft aragonite structure, gradually dissolve and fall off (scale removal), thereby preventing the formation of scale. The scale inhibitor alloy is a physical scale inhibitor, non-magnetic, non-electric, without an external power supply, without maintenance, zero carbon and zero emissions, long-term protection, activation of water body, without adding salt, without any external force and electricity, natural ecological soft water, environmentally friendly and safe, reducing the formation of scale and extending the service life of the product. In the embodiments of the present disclosure, the scale inhibitor alloy is an existing alloy, and the embodiments of the present disclosure do not improve the composition of the scale inhibitor alloy. The composition of the scale inhibitor alloy can be mainly copper and nickel elements. In addition, the composition of the scale inhibitor alloy can also include other elements such as iron and cobalt elements.

[0068] The scale inhibition principle of polyphosphate is mainly to interfere with the normal growth of calcium carbonate crystals, control the rate of crystal nucleus formation, and prevent its deposition to form scale. Moreover, polyphosphate can also undergo complexation or chelation reactions with solids (scale) containing calcium, magnesium, iron and other metals that have already formed, redisperse these already formed solids (scale) into the water, gradually reduce fouling, and clean the pipeline. This mechanism of action not only effectively eliminates the phenomenon of red water in the pipeline, but also makes the crystal grow slowly through the dispersion effect, effectively inhibiting the formation of scale. In addition, polyphosphate can also form monocyclic or dicyclic chelates with calcium ions and magnesium ions in the water, and these chelates can increase the solubility of scale, thereby reducing its deposition on the inner wall of the pipeline.

[0069] In addition, in some embodiments, the scale inhibitor unit 232 can also be a filter element to filter out scale-forming substances in the water.

[0070] In an exemplary embodiment, such as Figure 14As shown, the number of scale inhibition units 232 is multiple. The scale inhibition units 232 are granular and filled in the accommodation cavity 503. The granular shape of the scale inhibition units 232 can increase the overall contact area between water and the scale inhibition units 232 filled in the accommodation cavity 503. For the material of the scale inhibition units 232 being scale inhibition alloy, the larger the contact area between water and the scale inhibition alloy, the larger the microcurrent generated, and the more free electrons in the water, thereby enhancing the scale inhibition effect. Moreover, the finer the particles of the scale inhibition alloy, the further the contact area with water can be increased, and thus the scale inhibition effect can be further improved. For the material of the scale inhibition units 232 being polyphosphate, the larger the contact area between water and polyphosphate, the faster the dilution rate of polyphosphate can be accelerated, and the concentration of polyphosphate in water can be increased, thereby enhancing the scale inhibition effect. Moreover, the finer the particles of polyphosphate, the further the contact area with water can be increased, and thus the dilution rate of polyphosphate can be further increased, improving the scale inhibition effect.

[0071] In the embodiments of the present disclosure, the shape of the particles can be regular shapes such as spherical, cuboid, conical or pyramidal, or can be an irregular shape. The particle sizes of the particles can be the same or different. According to the usage requirements, parameters such as the shape and particle size of the particles can be adjusted to ensure sufficient contact area with water and enable water to flow through the scale inhibition core assembly 23 at a certain speed.

[0072] In an exemplary embodiment, please also refer to Figure 7 , Figure 10 , Figure 12 and Figure 13 , the number of scale inhibition units 232 is multiple. The scale inhibition units 232 include sheet-like structures 2321. The multiple sheet-like structures 2321 are arranged at intervals along the water flow direction, and the sheet-like structures 2321 have at least one through hole 600. Thus, through the arrangement of the through holes 600, the speed of water flowing through the scale inhibition core assembly 23 can be ensured, the flow resistance of the scale inhibition core assembly 23 to water can be reduced, and the water outlet mechanism can achieve better water outlet patterns and water outlet strength. The multiple sheet-like structures 2321 are arranged at intervals along the water flow direction, so that both sides of the sheet-like structures 2321 opposite to each other along the water flow direction can have sufficient contact area with water, ensuring the scale inhibition effect.

[0073] In an exemplary embodiment, please also refer to Figure 7 , Figure 10 and Figure 13 , the sheet-like structures 2321 have multiple through hole groups, and the multiple through hole groups are coaxially arranged with the sheet-like structures 2321 and are sequentially distributed along the radial direction of the sheet-like structures 2321. Each through hole group includes multiple through holes 600, and the multiple through holes 600 are distributed around the axial direction of the sheet-like structures 2321. Thus, the sheet-like structures 2321 have multiple through holes 600 and are uniformly distributed around the axial direction of the sheet-like structures 2321, which can further increase the speed of water flowing through the scale inhibition core assembly 23.

[0074] The scale inhibition unit 232 further includes a guide portion 2322 . At least one through hole 600 is provided with a guide portion 2322 , which can partially shield the corresponding through hole 600 , so that water passing through the through hole 600 can contact the guide portion 2322 and flow in the direction of the guide portion 2322 .

[0075] One end of the flow guide 2322 is disposed on the sheet structure 2321, and the other end of the flow guide 2322 spirally extends around the axial direction of the sheet structure 2321, away from the water inlet end 501. This allows water to flow in a spiral, guided by the flow guide 2322, further increasing the speed of water flowing through the scale inhibition core assembly 23 and disturbing the water between adjacent scale inhibition units 232, thereby increasing the flow rate of water relative to the scale inhibition units 232. For scale inhibition units 232 made of a scale inhibition alloy, the increased flow rate increases the microcurrent generated by the scale inhibition alloy, increasing the number of free electrons in the water, and thus enhancing the scale inhibition effect. For scale inhibition units 232 made of polyphosphate, the increased flow rate accelerates the dilution rate of the polyphosphate, increasing the concentration of polyphosphate in the water, thereby enhancing the scale inhibition effect.

[0076] In the embodiment of the present disclosure, the number of via groups is two, wherein the number of vias 600 in the via group located radially inward of the sheet structure 2321 is four, and the vias 600 are evenly distributed axially around the sheet structure 2321, and the shape of the vias 600 in the via group located radially inward of the sheet structure 2321 is fan-shaped. The number of vias 600 in the via group located radially outward of the sheet structure 2321 is five, and the vias 600 are evenly distributed axially around the sheet structure 2321, and the shape of the vias 600 in the via group located radially outward of the sheet structure 2321 is fan-shaped. It can be understood that in other embodiments, the number of via groups can also be one or more than three. The number of vias 600 in each via group can also be other values. The shape of the vias 600 can also be regular shapes such as circles, ellipses, rectangles, diamonds, trapezoids, etc., or irregular shapes.

[0077] The sheet structure 2321 includes a first annular portion 23211 and a second annular portion 23212. The first annular portion 23211 and the second annular portion 23212 are coaxially arranged, with the second annular portion 23212 located circumferentially outside the first annular portion 23211. A plurality of first connecting rods 23213 are arranged inside the first annular portion 23211, with one end intersecting the other end. The other ends of the first connecting rods 23213 are connected to the first annular portion 23211, dividing the area enclosed by the first annular portion 23211 into a plurality of vias 600.

[0078] A plurality of second connecting rods 23214 are arranged at intervals between the first annular part 23211 and the second annular part 23212, dividing the area enclosed between the first annular part 23211 and the second annular part 23212 into a plurality of through holes 600.

[0079] The first connecting rod 23213 and the second connecting rod 23214 can extend along the radial direction of the sheet-like structure 2321, or can extend obliquely relative to the radial direction of the sheet-like structure 2321.

[0080] In the embodiment of the present disclosure, a flow guiding part 2322 is arranged in each through hole 600.

[0081] Among them, for the through hole 600 in the through hole group located radially inside the sheet-like structure 2321, the flow guiding part 2322 is arranged on one of the two first connecting rods 23213 facing the through hole 600, and a fillet transition is provided between the other of the two first connecting rods 23213 facing the through hole 600 and the first annular part 23211 to improve the connection stability and avoid breakage under the impact of water.

[0082] For the through hole 600 in the through hole group located radially outside the sheet-like structure 2321, the flow guiding part 2322 is arranged on one of the two second connecting rods 23214 facing the through hole 6I00, and fillet transitions are provided between the other of the two second connecting rods 23214 facing the through hole 600 and the first annular part 23211 and between the other of the two second connecting rods 23214 facing the through hole 600 and the second annular part 23212 to improve the connection stability and avoid breakage under the impact of water.

[0083] In the embodiment of the present disclosure, the inner wall cross-section of the core shell 231 forming the accommodation cavity 503 is circular, and the circumferential outer side of the second annular part 23212 matches the inner wall and is also circular. It can be understood that in other embodiments, the inner wall cross-section can also be a regular figure such as an ellipse, a triangle, a rectangle, a rhombus, a trapezoid, etc., or an irregular figure.

[0084] In an exemplary embodiment, such as Figure 13As shown, the spiral extension directions of the diversion portions 2322 in adjacent via groups are different, such that the flow directions of the water at the axis position of the core shell 231 within the core shell 231 and the water away from the axis position of the core shell 231 are different. In this way, the disturbance effect on the water can be further increased, the flow rate of the water relative to the scale inhibition unit 232 can be further increased, and the scale inhibition effect can be improved. In the embodiments of the present disclosure, the spiral extension direction of the diversion portion 2322 in the inner via group among the two via groups is clockwise spiral extension. The spiral extension direction of the diversion portion 2322 in the outer via group among the two via groups is counterclockwise spiral extension. It can be understood that in other embodiments, the spiral extension direction of the diversion portion 2322 in the inner via group among the two via groups is counterclockwise spiral extension. The spiral extension direction of the diversion portion 2322 in the outer via group among the two via groups is clockwise spiral extension. In addition, in some embodiments, the spiral extension directions of the diversion portions 2322 in adjacent via groups may also be the same.

[0085] In an exemplary embodiment, please also refer to Figure 5 、 Figure 7 、 Figure 10 、 Figure 12 and Figure 14 wherein the core shell 231, the water inlet end 501, the water outlet end 502, the accommodation cavity 503, and the sheet-like structure 2321 are coaxially arranged. In this way, when water enters the accommodation cavity 503, it can contact the scale inhibition unit 232 relatively uniformly, ensuring the scale inhibition effect. Moreover, it also makes the flow direction of the water more stable after passing through the scale inhibition unit 232.

[0086] In the embodiments of the present disclosure, the cross-sections of the water inlet end 501, the water outlet end 502, and the accommodation cavity 503 are all circular. It can be understood that in other embodiments, the cross-sections of the water inlet end 501, the water outlet end 502, and the accommodation cavity 503 may also be regular figures such as ellipses, triangles, rectangles, rhombuses, trapezoids, etc., or may be irregular figures.

[0087] In an exemplary embodiment, as Figure 8 and Figure 12As shown, the core shell 231 includes a plurality of detachably connected shells 2311. This facilitates the installation of the scale inhibitor unit 232. The plurality of shells 2311 enclose an accommodation cavity 503. The shells 2311 can be connected by snap connection or plug connection. In the embodiment of the present disclosure, on the two axially opposite sides of the core shell 231, a plug portion 23111 and a plug slot 700 are respectively provided around the core shell 231. The plug portion 23111 can be received in the plug slot 700 on an adjacent shell 2311, and the plug slot 700 can accommodate the plug portion 23111 on an adjacent shell 2311 to achieve plug connection between adjacent shells 2311. It can be understood that in other embodiments, after the installation of the scale inhibitor unit 232 is completed, adjacent shells 2311 can also be connected into one body by bonding or ultrasonic welding.

[0088] On one side of the shell 2311 facing the accommodation cavity, a positioning portion 23112 is provided, and the circumferential outer side of the sheet-like structure 2321 is installed on the positioning portion 23112. In this way, through the setting of the positioning portion 23112, the connection stability between the sheet-like structure 2321 and the core shell 231 can be increased, thereby improving the water impact resistance of the scale inhibitor unit 232 and ensuring the stable position of the scale inhibitor unit 232 relative to the core shell 231. In the embodiment of the present disclosure, the positioning portion 23112 has an annular groove, and the circumferential outer side of the sheet-like structure 2321 can be partially received in the annular groove to be connected to the positioning portion 23112. It can be understood that in other embodiments, the positioning portion 23112 is a ring-shaped protrusion and is arranged around the axis of the core shell 231, and a ring-shaped groove capable of receiving the ring-shaped protrusion is provided on the circumferential outer side of the sheet-like structure 2321.

[0089] In an exemplary embodiment, please also refer to Figures 3 to 5 、 Figure 7 and Figure 10 , the axis of the valve body 21 is parallel to the first direction. Among them, the first direction is parallel to the direction indicated by the arrow X in Figures 3 to 5 and Figure 12 .

[0090] On the two axially opposite sides of the valve body 21 along the first direction, a water inlet 100 and a mounting hole 400 are respectively provided to facilitate the scale inhibitor core assembly 23 to drive the water stop valve 22 installed at the water inlet 100 along the first direction. The water outlet 200 is provided on the circumferential outer side of the valve body 21 around the first direction. The water outlet 200 can be provided on the circumferential outer side of the valve body 21 around the first direction and on the side far from the water inlet 100, so that there is enough space between the water inlet 100 and the water outlet 200 to accommodate more scale inhibitor units 232 through the core shell 231 and improve the scale inhibition effect.

[0091] In an exemplary embodiment, please also refer to Figure 5 、 Figure 7 and Figure 10, the scale inhibitor core assembly 23 further includes a housing 233. The housing 233 is coaxially arranged with the valve body 21. One end of the housing 233 close to the water inlet 100 is provided with a first flow-through hole 801, and the first flow-through hole 801 is coaxially arranged with the water inlet end 501, so that after water enters the water inlet end 501 through the first flow-through hole 801, it can be more evenly distributed in the accommodation cavity 503. The first flow-through hole 801 communicates with the water inlet 100 and the water inlet end 501. A second flow-through hole 802 is provided on the circumferential outer side of the housing 233 to facilitate communication with the water outlet 200. The second flow-through hole 802 communicates between the water outlet end 502 and the water outlet 200. The valve body 21 and the housing 233 are detachably connected.

[0092] In an exemplary embodiment, as Figure 4 and Figure 5 shown, one of the valve body 21 and the housing 233 is provided with a connection groove 803 extending around the first direction. The other of the valve body 21 and the housing 233 is provided with a protrusion 211.

[0093] After the scale inhibitor core assembly 23 is installed in the installation cavity 300 through the installation hole 400, it can rotate relative to the valve body 21 around the first direction. The protrusion 211 is received in the connection groove 803, and the protrusion 211 can be oppositely arranged and abutted against the groove wall of the connection groove 803 along the first direction to limit the scale inhibitor core assembly 23 from moving out of the installation cavity 300 through the installation hole 400. Or the protrusion 211 is removed from the connection groove 803, so that the scale inhibitor core assembly 23 can move out of the installation cavity 300 through the installation hole 400. Thus, through the arrangement of the connection groove 803 and the protrusion 211, the detachable connection between the scale inhibitor core assembly 23 and the valve body 21 can be realized by rotating the scale inhibitor core assembly 23 relative to the valve body 21 around the first direction. By abutting the protrusion 211 against the groove wall of the connection groove 803, the position stability of the scale inhibitor core assembly 23 relative to the valve body 21 can be ensured, and further the driving stability of the scale inhibitor core assembly 23 to the water stop valve 22 can be ensured, and the connection stability between the water inlet 100 and the installation cavity 300 can be ensured. It can be understood that in other embodiments, the scale inhibitor core assembly 23 and the valve body 21 can also be detachably connected by a buckle.

[0094] In an embodiment of the present disclosure, a connection groove 803 is provided on the outer shell 233. A convex portion 211 is provided on the valve body 21. One end of the outer shell 233 away from the first flow-through hole 801 further has a knob 2331 to facilitate driving the scale inhibitor core assembly 23 to rotate relative to the valve body 21. The connection groove 803 can be located in a plane perpendicular to the first direction or extend spirally around the first direction. Wherein, the connection groove 803 extends spirally around the first direction, so that the groove wall of the connection groove 803 can increase or decrease the abutting force acting on the convex portion 211 during the rotation of the scale inhibitor core assembly 23 relative to the valve body 21. Among them, increasing the abutting force acting on the convex portion 211 can further ensure the stability of driving the water stop valve 22. Reducing the abutting force acting on the convex portion 211 can gradually change the limiting range of the convex portion 211 on the movement of the scale inhibitor core assembly 23 relative to the valve body 21 along the first direction, avoiding the sudden failure of the restriction of the convex portion 211 on the scale inhibitor core assembly 23, and causing the scale inhibitor core assembly 23 to fly out of the mounting hole 400 under the action of water pressure, resulting in danger. The outer shell 233 is further provided with a guiding surface 2332 at the starting end of the connection groove 803 to facilitate guiding the convex portion 211 into the connection groove 803.

[0095] In an exemplary embodiment, please also refer to Figure 7 and Figure 10 , at least one of the valve body 21 and the outer shell 233 has a sealing portion, and the sealing portion can cooperate with the other of the valve body 21 and the outer shell 233 to seal the mounting hole 400 to prevent water from flowing out of the mounting hole 400. In an embodiment of the present disclosure, the valve body 21 has a sealing portion, and the sealing portion is a conical surface 212. The outer shell 233 has a sealing portion, and the sealing portion is an annular protrusion 2333. The large end side of the conical surface 212 faces the mounting hole 400. The circumferential outer side of the annular protrusion 2333 can abut and seal with the conical surface 212 to seal the mounting hole 400.

[0096] In an exemplary embodiment, please also refer to Figure 4 , Figure 5 and Figure 8 , an annular groove 804 extending around the first direction is provided on the circumferential outer side of the outer shell 233. The number of the second flow-through holes 802 is multiple, and the multiple second flow-through holes 802 are provided at the bottom of the annular groove 804. In this way, the provision of the annular groove 804 can ensure sufficient water flow into the water outlet 200, and the annular groove 804 can play a certain role in rectifying the water and discharging it into the water outlet 200, preventing the water with spiral disturbance from directly discharging into the water outlet 200 through the second flow-through holes 802.

[0097] The outer shell 233 is a detachable structure. For example, the outer shell 233 can include a main body 2334 and a cover body 2335 to facilitate the installation of the core shell 231 with the scale inhibitor unit 232 into the outer shell 233.

[0098] In an exemplary embodiment, please also refer to Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 9 , Figure 10 and Figure 11 . The water stop valve 22 includes a valve core 221 and a reset member 222. The valve core 221 is movably installed at the water inlet 100 and can move relative to the valve body 21 along a direction parallel to the first direction. The movement path of the valve core 221 is eccentrically arranged with respect to the axial direction of the first flow-through hole 801 and is located outside the circumferential direction of the first flow-through hole 801. In this way, when the scale inhibitor core assembly 23 drives the valve core 221, the valve core 221 is prevented from blocking the first flow-through hole 801, ensuring that water can smoothly enter the first flow-through hole 801. In the embodiment of the present disclosure, the reset member 222 is a spring.

[0099] The valve core 221 is arranged to move relative to the valve body 21 along a direction parallel to the first direction under the drive of the scale inhibitor core assembly 23, communicate the water inlet 100 with the installation cavity 300, and cause the reset member 222 to generate a driving force for resetting the valve core 221.

[0100] In the embodiment of the present disclosure, the water inlet 100 is eccentrically arranged with respect to the axial direction of the first flow-through hole 801. The movement path of the valve core 221 is coaxially arranged with the water inlet 100. The valve core 221 has a sealing member 2211, and the sealing member 2211 can cooperate with the valve body 21 to disconnect the water inlet 100 and the installation cavity 300. In the embodiment of the present disclosure, in order to ensure the stability of the disconnection between the water inlet 100 and the installation cavity 300 and avoid the assembly error between the water stop valve 22 and the valve body 21 resulting in the sealing member 2211 being unable to cooperate with the valve body 21 to disconnect the water inlet 100 and the installation cavity 300, the water stop valve 22 is further provided with an outer housing 223. The outer housing 223 is installed at the water inlet 100 and fixedly connected to the valve body 21.

[0101] The valve core 221 moves relative to the valve body 21 along a direction parallel to the first direction under the drive of the scale inhibitor core assembly 23, and thus moves relative to the outer housing 223, so that the outer circumferential side of the seal 2211 can be separated from the inner wall of the outer housing 223, and the water inlet 100 and the installation cavity 300 are communicated. The reset member 222 can be arranged between the valve core 221 and the outer housing 223 and is compressed by the valve core 221 to the outer housing 223 to generate a driving force for resetting the valve core 221. When the scale inhibitor core assembly 23 is separated from the valve core 221, the valve core 221 is reset under the drive of the reset member 222, so that the outer circumferential side of the seal 2211 can fit with the inner wall of the outer housing 223, and the water inlet 100 and the installation cavity 300 are disconnected. The outer housing 223 is a detachable structure and can include a main body portion 2231 and a cover portion 2232 to facilitate the installation of the valve core 221 and the reset member 222. The valve core 221 can be slidably connected to at least one of the main body portion 2231 and the cover portion 2232. The cover portion 2232 is provided with an opening 900 to enable water to enter the water inlet 100.
