[0064] 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.

[0065] The scale inhibition unit in the existing scale inhibition structure is made of a single material and cannot achieve a better scale inhibition effect.

[0066] The disclosed embodiments provide a scale inhibition core assembly, a scale inhibition mechanism, and a water outlet device. The water outlet device can be installed in various environments such as companies, schools, homes, and factories to achieve cleaning of items and body parts to be cleaned, thereby improving and enhancing people's quality of life and health.

[0067] Please combine Figures 1 to 7 、 Figure 13 and Figure 14 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.

[0068] The scale inhibition mechanism 20 is provided at the water outlet body 10. The scale inhibition mechanism 20 includes a valve body 21 and a scale inhibition core assembly 22. The valve body 21 is provided with a water inlet 100, a water outlet 200 and an installation cavity 300. The installation cavity 300 is connected between the water inlet 100 and the water outlet 200. The valve body 21 is also provided with a mounting hole 400, and the mounting hole 400 is connected to the installation cavity 300. The scale inhibition core assembly 22 is detachably connected to the valve body 21. The scale inhibition core assembly 22 is configured to be installed in the installation cavity 300 through the mounting hole 400 and is located between the water inlet 100 and the water outlet 200, so that water can pass through the scale inhibition core assembly 22 and be discharged from the water outlet 200 after completing scale inhibition. The scale inhibition core assembly 22 is configured to be removed from the installation cavity 300 through the mounting hole 400. The water inlet 100 and the water outlet 200 are respectively connected to the waterway structure.

[0069] In the embodiment of the present disclosure, the water inlet valve 40 is connected between the water inlet connector 30 and the water inlet 100, and the water inlet valve 40 is configured to control the water flow rate entering the water inlet 100 from the water inlet connector 30. The number of water inlet connectors 30 can be one or more. For example, the number of water inlet connectors 30 can be two, which are connected to the hot water source and the cold water source respectively. The water inlet valve 40 is also configured to control the connection area between the two water inlet connectors 30 and the water inlet 100 to control the water temperature entering the water inlet 100. The water outlet device can also include multiple water outlet mechanisms. The water outlet mechanism can be, but is not limited to, a water faucet, a shower head, a top spray or a spray gun. The water outlet 200 can be connected to multiple water outlet mechanisms through a water diverter valve 50. After water enters the water inlet 100, it can be scale-protected by the scale-protection core assembly 22 located between the water inlet 100 and the water outlet 200, and discharged into the water diversion valve 50 from the water outlet 200. The user can control the water diversion valve 50 to introduce water into different water outlet mechanisms and discharge it.

[0070] The mounting hole 400 is exposed on the outlet body 10. In the disclosed embodiment, the outlet body 10 is provided with an escape hole 500 to allow the mounting hole 400 to be exposed on the outlet body 10, facilitating replacement of the scale inhibition core assembly 22. Furthermore, the majority of the scale inhibition mechanism 20 and the waterway structure are located within the outlet body 10. Furthermore, the connection points between the water inlet 100 and the water outlet 200 and the waterway structure are also located within the outlet body 10, ensuring the overall aesthetics of the water outlet device.

[0071] The mounting hole 400 is independently arranged relative to the water inlet 100 and the water outlet 200, so as to avoid the scale inhibition core assembly 22 being installed in the mounting cavity 300 or removed from the mounting cavity 300 through the mounting hole 400, thereby preventing the original connection relationship between the water inlet 100 and the water outlet 200 and the water channel structure from being destroyed. The mounting hole 400 can also be exposed on the outer surface of the water outlet device, thereby facilitating the user to replace the scale inhibition core assembly 22.

[0072] Please combine Figure 6 and Figure 7 The scale inhibition core assembly 22 includes a core shell 221, a first scale inhibition unit 222, and a second scale inhibition unit 223. The core shell 221 has an inlet end 501 and a water outlet end 502. The inlet end 501 is connected to the water inlet 100, and the water outlet end 502 is connected to the water outlet 200. The core shell 221 also has a receiving chamber 503, which is connected between the inlet end 501 and the water outlet end 502. The receiving chamber 503 includes a first installation space 5031 arranged near the water inlet end 501 and a second installation space 5032 arranged near the water outlet end 502. The first scale inhibition unit 222 is installed in the first installation space 5031. The second scale inhibition unit 223 is installed in the second installation space 5032. The first scale inhibition unit 222 and the second scale inhibition unit 223 are made of different materials. The material of the first scale inhibition unit 222 can be one of a scale inhibition alloy and polyphosphate, and the material of the second scale inhibition unit 223 can be the other of the scale inhibition alloy and polyphosphate. The different materials of the first scale inhibition unit 222 and the second scale inhibition unit 223 allow the second scale inhibition unit 223 to continue to inhibit scale in the water after the first scale inhibition unit 222 has completed the scale inhibition, thereby compensating for the insufficient scale inhibition of the first scale inhibition unit 222 and improving the scale inhibition effect of the scale inhibition core assembly 22.

[0073] Furthermore, in some embodiments, Figure 13 and Figure 14 As shown, the water outlet device can also be, but not limited to, a separate water outlet faucet, shower head, overhead spray or spray gun. The water outlet device includes a water outlet assembly 60 and a scale inhibition core assembly 22, and the water outlet end 502 is connected to the water outlet assembly 60. In this way, water can pass through the first scale inhibition unit 222 and the second scale inhibition unit 223 in sequence and then be discharged from the water outlet assembly 60. The water outlet assembly 60 can be, but not limited to, a faucet water outlet assembly, a shower water outlet assembly, a overhead spray water outlet assembly or a spray gun water outlet assembly. The water outlet device can also include a shell structure 70. The shell structure 70 is mounted on the scale inhibition core assembly 22 to protect the scale inhibition core assembly 22. The shell structure 70 and the scale inhibition core assembly 22 are detachably connected to facilitate the replacement of the scale inhibition core assembly 22.

[0074] The outer shell structure 70 can also be connected to the water outlet assembly 60 to improve the connection stability between the scale inhibition core assembly 22 and the water outlet assembly 60. The connection methods of the outer shell structure 70 and the water outlet assembly 60 include but are not limited to snap connection, plug connection, thread connection or welding. In addition, when the water outlet device is a shower (such as Figure 13 and Figure 14 ) and the spray gun embodiment, the housing structure 70 can also be used as a handheld structure.

[0075] In the embodiment of the present disclosure, the material of the first scale inhibition unit 222 is a scale inhibition alloy, and the material of the second scale inhibition unit 223 is polyphosphate.

[0076] The scale-inhibiting alloy can release free electrons into the water flowing through the first scale-inhibiting unit 222. 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-inhibiting alloy can also change the crystal structure of scale such as calcium carbonate, so that it changes from a hard marble structure to a soft aragonite structure, gradually dissolving and falling off (scaling), thereby preventing the formation of scale. The scale-inhibiting alloy is a physical scale inhibitor, non-magnetic and non-electric, does not require an external power supply, does not require maintenance, is zero-carbon and zero-emission, provides long-term protection, activates water bodies, does not require the addition of salt, does not require any external force or electricity, naturally softens water, is environmentally friendly and safe, reduces scale formation, and extends product service life. In the embodiment of the present disclosure, the scale-inhibiting alloy is an existing alloy, and the embodiment of the present disclosure does not improve the composition of the scale-inhibiting alloy. The composition of the scale-inhibiting alloy can be mainly copper and nickel. In addition, the composition of the scale-inhibiting alloy can also include other elements such as iron and cobalt.

[0077] The first scale inhibition unit 222 has at least one through-hole 600. This through-hole 600 ensures the speed at which water flows through the first scale inhibition unit 222, reducing resistance to water flow. After passing through the through-hole 600, the water flows into the second installation space 5032, where the second scale inhibition unit 223 continues to inhibit scale.

[0078] The scale inhibition principle of polyphosphate is mainly to interfere with the normal growth of calcium carbonate crystals, control the speed of crystal nucleation formation, and prevent them from depositing and forming scale. In addition, polyphosphate can also undergo complexation or chelation reactions with solids (scale) containing metals such as calcium, magnesium, and iron, and redisperse these already formed solids (scale) into the water, gradually reducing scale accumulation and cleaning the pipes. This mechanism of action not only effectively eliminates the red water phenomenon in the pipes, but also slows down the growth of crystals through dispersion, effectively inhibiting the formation of scale. In addition, polyphosphate can also form monocyclic or bicyclic chelates with calcium ions and magnesium ions in water. These chelates can increase the solubility of scale, thereby reducing its deposition on the inner wall of the pipe. The setting of polyphosphate can make up for the insufficient scale inhibition of scale-inhibiting alloys and further enhance the scale inhibition effect.

[0079] Multiple second scale inhibition units 223 are provided, each in a granular form, and are filled within the second installation space 5032. The granular form of the second scale inhibition units 223 increases the overall contact area between water and the second scale inhibition units 223 within the second installation space 5032. For polyphosphate, a larger contact area between water and polyphosphate accelerates its dilution rate, increasing its concentration in the water and thereby enhancing its scale inhibition effect. Furthermore, finer polyphosphate particles further increase its contact area with water, further increasing its dilution rate and improving its scale inhibition effect.

[0080] In the disclosed embodiments, the particles can be regular shapes such as spheres, cuboids, cones, or pyramids, or they can be irregular shapes. The particle sizes can be the same or different. Parameters such as particle shape and size can be adjusted based on usage requirements to ensure sufficient contact area with water and a certain velocity at which water flows through the second scale inhibition unit 223.

[0081] The configuration of the core shell 221 provides a relatively stable working environment for the first scale inhibition unit 222 and the second scale inhibition unit 223, thereby ensuring the stability of the operation of the first scale inhibition unit 222 and the second scale inhibition unit 223. In addition, the water inlet end 501 and the water outlet end 502 provided on the core shell 221 provide a certain flow direction for water, ensuring that the water can effectively contact the first scale inhibition unit 222 and the second scale inhibition unit 223, thereby improving the scale inhibition effect.

[0082] The scale inhibition core assembly 22 (scale inhibition structure) of the above-mentioned scheme is applied and equipped in the scale inhibition mechanism 20 and the water outlet device, which can enhance the scale inhibition effect of the scale inhibition mechanism 20 and the water outlet device. Specifically, the scale inhibition core assembly 22 includes a core shell 221 having a water inlet end 501, a water outlet end 502 and a accommodating chamber 503, a first scale inhibition unit 222 and a second scale inhibition unit 223. The first scale inhibition unit 222 has at least one through hole 600. The first scale inhibition unit 222 is installed in the first installation space 5031 provided in the accommodating chamber 503 near the water inlet end 501. The number of the second scale inhibition units 223 is plural, in the form of particles, and filled in the second installation space 5032 provided in the accommodating chamber 503 near the water outlet end 502. Among them, the material of the first scale inhibition unit 222 is a scale inhibition alloy, which can release free electrons into the water flowing through the first scale inhibition unit 222. The material of the second scale inhibition unit 223 is polyphosphate, which can be gradually diluted and discharged into the water after contacting with water, so as to make up for the deficiency of free electron scale inhibition and improve the scale inhibition effect of the scale inhibition core component 22 .

[0083] In the exemplary embodiment, please combine Figure 6 and Figure 7 The first scale inhibition unit 222 is provided in a plurality. The first scale inhibition unit 222 includes a sheet structure 2221. The sheet structures 2221 are spaced apart along the water flow direction, and the vias 600 are provided in the sheet structures 2221. The sheet structures 2221 are spaced apart along the water flow direction, ensuring sufficient contact area with water on both sides of the sheet structures 2221 facing away from each other along the water flow direction. This increases the contact area between the water and the scale inhibition alloy, thereby increasing the release of free electrons and ensuring a good scale inhibition effect.

[0084] In the exemplary embodiment, please combine Figure 6 、 Figure 7 and Figure 9The sheet structure 2221 has multiple through-hole groups, which are coaxially arranged with the sheet structure 2221 and distributed sequentially along the radial direction of the sheet structure 2221. Each through-hole group includes multiple through-holes 600, and the through-holes 600 are distributed axially around the sheet structure 2221. This ensures that the sheet structure 2221 has multiple through-holes 600 that are evenly distributed axially around the sheet structure 2221, further increasing the speed at which water flows through the scale inhibition core assembly 22.

[0085] The first scale inhibition unit 222 further includes a guide portion 2222. At least one through hole 600 is provided with a guide portion 2222, which can partially shield the corresponding through hole 600, so that water passing through the through hole 600 can contact the guide portion 2222 and flow in the guiding direction of the guide portion 2222.

[0086] One end of the guide portion 2222 is disposed on the sheet structure 2221, and the other end of the guide portion 2222 spirally extends around the axial direction of the sheet structure 2221 toward the side away from the water inlet end 501. This allows the water to flow in a spiral under the guidance of the guide portion 2222, further increasing the speed of water flowing through the scale inhibition core assembly 22 and disturbing the water between adjacent first scale inhibition units 222, thereby increasing the flow rate of water relative to the first scale inhibition unit 222. For the 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. After the water is accelerated through the first scale inhibition unit 222, it can accelerate the dilution rate of the polyphosphate when passing through the second scale inhibition unit 223, allowing the water to fully react with the polyphosphate, increasing the concentration of polyphosphate in the water, thereby enhancing the scale inhibition effect.

[0087] 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 2221 is four, and the vias 600 are evenly distributed axially around the sheet structure 2221, and the shape of the vias 600 in the via group located radially inward of the sheet structure 2221 is fan-shaped. The number of vias 600 in the via group located radially outward of the sheet structure 2221 is five, and the vias 600 are evenly distributed axially around the sheet structure 2221, and the shape of the vias 600 in the via group located radially outward of the sheet structure 2221 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.

[0088] The sheet structure 2221 includes a first annular portion 22211 and a second annular portion 22212. The first annular portion 22211 and the second annular portion 22212 are coaxially arranged, with the second annular portion 22212 located circumferentially outside the first annular portion 22211. A plurality of first connecting rods 22213 are arranged inside the first annular portion 22211, with one end intersecting the other end. The other ends of the first connecting rods 22213 are connected to the first annular portion 22211, dividing the space enclosed by the first annular portion 22211 into a plurality of vias 600.

[0089] A plurality of second connecting rods 22214 spaced apart are connected between the first annular portion 22211 and the second annular portion 22212 , dividing the area enclosed by the first annular portion 22211 and the second annular portion 22212 into a plurality of through holes 600 .

[0090] The first connecting rod 22213 and the second connecting rod 22214 may extend along the radial direction of the sheet structure 2221 , or may extend obliquely relative to the radial direction of the sheet structure 2221 .

[0091] In the embodiment of the present disclosure, each via hole 600 is provided with a guide portion 2222 .

[0092] Among them, for the via 600 in the via group located radially inside the sheet structure 2221, the guide portion 2222 is arranged on one of the two first connecting rods 22213 facing the via 600, and there is a rounded transition between the other of the two first connecting rods 22213 facing the via 600 and the first annular portion 22211 to improve the stability of the connection and avoid breakage under the impact of water.

[0093] For the via 600 in the via group located radially outside the sheet structure 2221, the guide portion 2222 is arranged on one of the two second connecting rods 22214 facing the via 600, and the other of the two second connecting rods 22214 facing the via 600 has a rounded transition between the first annular portion 22211 and the second annular portion 22212 to improve the stability of the connection and avoid breakage under the impact of water.

[0094] In the disclosed embodiment, the inner wall of the core shell 221 forming the accommodating cavity 503 has a circular cross-section, and the circumferential outer side of the second annular portion 22212 matches the inner wall and is also circular. It is understood that in other embodiments, the inner wall cross-section may also be a regular shape such as an ellipse, triangle, rectangle, diamond, trapezoid, or an irregular shape.

[0095] In an exemplary embodiment, as Figure 9As shown, the spiral extension directions of the guide portions 2222 in adjacent via groups are different, so that the flow direction of the water located at the axis position of the core shell 221 in the core shell 221 is different from the flow direction of the water away from the axis position of the core shell 221. This can further increase the disturbance effect on the water, further increase the flow rate of the water, and improve the scale prevention effect. In the embodiment of the present disclosure, the spiral extension direction of the guide portion 2222 in the via group located on the inner side of the two via groups is a clockwise spiral extension. The spiral extension direction of the guide portion 2222 in the via group located on the outer side of the two via groups is a counterclockwise spiral extension. It can be understood that in other embodiments, the spiral extension direction of the guide portion 2222 in the via group located on the inner side of the two via groups is a counterclockwise spiral extension. The spiral extension direction of the guide portion 2222 in the via group located on the outer side of the two via groups is a clockwise spiral extension. In addition, in some embodiments, the spiral extension directions of the guide portions 2222 in adjacent via groups may also be the same.

[0096] In the exemplary embodiment, please combine Figures 5 to 7 The core housing 221, the water inlet end 501, the water outlet end 502, the first installation space 5031, the second installation space 5032, and the sheet structure 2221 are coaxially arranged. This ensures that water entering the accommodating cavity 503 can relatively evenly contact the first scale inhibition unit 222 and the second scale inhibition unit 223, ensuring the scale inhibition effect. In addition, the flow direction of water after passing through the first scale inhibition unit 222 is more stable.

[0097] In the embodiment of the present disclosure, the cross-sections of the water inlet end 501, the water outlet end 502, and the accommodating cavity 503 are all circular. It is understood that in other embodiments, the cross-sections of the water inlet end 501, the water outlet end 502, the first installation space 5031, and the second installation space 5032 may also be regular shapes such as elliptical, triangular, rectangular, diamond, trapezoidal, or irregular shapes.

[0098] In an exemplary embodiment, as Figure 5 、 Figure 6 and Figure 14 As shown, the core housing 221 comprises a detachably connected housing 2211 and an end cap 2212. This facilitates installation of the first scale inhibition unit 222 and the second scale inhibition unit 223. The end cap 2212 covers the side of the housing 2211 near the water inlet 501. The housing 2211 and the end cap 2212 together form a receiving chamber 503. The end cap 2212 has grille holes to form the water inlet 501. The grille holes prevent large impurities from entering the receiving chamber 503.

[0099] The shell 2211 and the end cover 2212 can be connected by snapping or plugging. In the embodiment of the present disclosure, the shell 2211 is axially provided with a plurality of plug-in grooves 700 around the core shell 221. The end cover 2212 is provided with a plurality of plug-in portions 22121. The plug-in portions 22121 can be accommodated in the plug-in grooves 700 in a one-to-one correspondence to achieve a plug-in connection between adjacent shells 2211 and end covers 2212. It can be understood that in other embodiments, after the installation of the first scale inhibition unit 222 and the second scale inhibition unit 223 is completed, the shell 2211 and the end cover 2212 can also be connected as a whole by bonding or ultrasonic welding.

[0100] The sheet structure 2221 and the shell 2211 can be connected as a whole by bonding or ultrasonic welding. In addition, in some embodiments, a positioning portion can be provided on the side of the shell 2211 facing the accommodating cavity 503, and the circumferential outer side of the sheet structure 2221 is installed on the positioning portion. In this way, the setting of the positioning portion can increase the connection stability between the sheet structure 2221 and the core shell 221, thereby improving the ability of the first scale inhibition unit 222 to resist water impact and ensuring the stability of the position of the first scale inhibition unit 222 relative to the core shell 221. The positioning portion can have an annular groove, and the circumferential outer side of the sheet structure 2221 can be partially accommodated in the annular groove to connect with the positioning portion. It can be understood that in other embodiments, the positioning portion can also be an annular protrusion, and is arranged axially around the core shell 221, and the circumferential outer side of the sheet structure 2221 is provided with an annular groove that can accommodate the annular protrusion.

[0101] In the exemplary embodiment, please combine Figure 3 and Figure 4 , the axial direction of the valve body 21 is parallel to the first direction. Figure 3 and Figure 4 The direction indicated by the arrow X.

[0102] The valve body 21 is provided with a water inlet 100 and a mounting hole 400 on opposite sides along a first direction. The water outlet 200 is provided on the outer side of the valve body 21 in the circumferential direction around the first direction. The water outlet 200 can be located on the outer side of the valve body 21 in the circumferential direction around the first direction, away from the water inlet 100, to ensure sufficient space between the water inlet 100 and the water outlet 200. This allows the core housing 221 to accommodate more first and second scale inhibition units 222, 223, thereby improving the scale inhibition effect.

[0103] In the exemplary embodiment, please combine Figure 5 、 Figure 7 and Figure 8The scale inhibition core assembly 22 also includes a shell 224. The shell 224 is coaxially arranged with the valve body 21. A first flow hole 801 is provided at one end of the shell 224 close to the water inlet 100. The first flow hole 801 is coaxially arranged with the water inlet end 501, so that water can be more evenly distributed in the first installation space 5031 after entering the water inlet end 501 through the first flow hole 801. The first flow hole 801 is connected between the water inlet 100 and the water inlet end 501. A second flow hole 802 is provided on the circumferential outer side of the shell 224 to facilitate communication with the water outlet 200. The second flow hole 802 is connected between the water outlet end 502 and the water outlet 200. The valve body 21 and the shell 224 are detachably connected.

[0104] In an exemplary embodiment, as Figure 4 and Figure 5 As shown, one of the valve body 21 and the housing 224 is provided with a connecting groove 803 extending around the first direction. The other of the valve body 21 and the housing 224 is provided with a protrusion 211.

[0105] After the scale inhibition core assembly 22 is installed in the mounting cavity 300 through the mounting hole 400, it can be rotated relative to the valve body 21 in a first direction, accommodating the protrusion 211 in the connecting groove 803. The protrusion 211 can be positioned opposite and abutted against the wall of the connecting groove 803 along the first direction, thereby restricting the scale inhibition core assembly 22 from being removed from the mounting cavity 300 through the mounting hole 400. Alternatively, the protrusion 211 can be removed from the connecting groove 803, allowing the scale inhibition core assembly 22 to be removed from the mounting cavity 300 through the mounting hole 400. In this manner, through the arrangement of the connecting groove 803 and the protrusion 211, the scale inhibition core assembly 22 can be detachably connected to the valve body 21 by rotating the scale inhibition core assembly 22 relative to the valve body 21 in the first direction. The abutment of the protrusion 211 against the wall of the connecting groove 803 ensures the positional stability of the scale inhibition core assembly 22 relative to the valve body 21. It can be understood that in other embodiments, the scale inhibition core assembly 22 and the valve body 21 can also be detachably connected by a buckle.

[0106] In the disclosed embodiment, the housing 224 is provided with a connecting groove 803. The valve body 21 is provided with a protrusion 211. The end of the housing 224 away from the first flow hole 801 also has a knob 2241 to facilitate driving the scale inhibition core assembly 22 to rotate relative to the valve body 21. The connecting groove 803 can be located in a plane perpendicular to the first direction or extend in a spiral shape around the first direction. The connecting groove 803 extends in a spiral shape around the first direction, so that the groove wall of the connecting groove 803 can increase or decrease the abutment force acting on the protrusion 211 during the process of rotating the scale inhibition core assembly 22 relative to the valve body 21. Reducing the abutment force acting on the protrusion 211 can gradually change the range of the protrusion 211's restriction on the scale inhibition core assembly 22 in the first direction relative to the valve body 21, thereby preventing the protrusion 211 from suddenly failing to restrict the scale inhibition core assembly 22, causing the scale inhibition core assembly 22 to fly out of the mounting hole 400 under the action of water pressure, thereby creating a dangerous situation. The housing 224 is further provided with a guide surface 2242 at the starting end of the connecting groove 803 to facilitate guiding the protrusion 211 into the connecting groove 803 .

[0107] In an exemplary embodiment, as Figure 7 As shown, at least one of the valve body 21 and the housing 224 has a sealing portion that can cooperate with the other of the valve body 21 and the housing 224 to seal the mounting hole 400, thereby preventing water from flowing out of the mounting hole 400. In the disclosed embodiment, the valve body 21 has a sealing portion in the form of a conical surface 212. The housing 224 has a sealing portion in the form of an annular protrusion 2243. The large end of the conical surface 212 faces the mounting hole 400. The circumferential outer side of the annular protrusion 2243 can abut against the conical surface 212 to seal the mounting hole 400.

[0108] In the exemplary embodiment, please combine Figure 4 、 Figure 5 and Figure 8 The outer circumferential surface of the housing 224 is provided with an annular groove 804 extending in a first direction. A plurality of second flow holes 802 are provided, each disposed at the bottom of the annular groove 804. The provision of the annular groove 804 ensures a sufficient flow of water entering the water outlet 200. Furthermore, the annular groove 804 provides a certain degree of rectification for the water flowing into the water outlet 200, preventing spirally disturbed water from being discharged directly into the water outlet 200 through the second flow holes 802.

[0109] The shell 224 is a detachable structure. For example, the shell 224 may include a body 2244 and a cover 2245 to facilitate installation of the core shell 221 with the first scale inhibition unit 222 and the second scale inhibition unit 223 installed on the shell 224 .

[0110] In the exemplary embodiment, please combine Figure 3 and Figures 10 to 12 The scale prevention mechanism 20 further includes a water stop valve 23 , which is installed at the water inlet 100 and can disconnect the water inlet 100 from the installation cavity 300 .

[0111] The scale inhibition core assembly 22 is installed in the installation cavity 300 through the installation hole 400 and can also drive the water stop valve 23 to connect the water inlet 100 with the installation cavity 300, allowing water to pass through the scale inhibition core assembly 22 and be discharged from the water outlet 200 after completing scale inhibition. The scale inhibition core assembly 22 is removed from the installation cavity 300 through the installation hole 400 and can also be separated from the water stop valve 23 to reset the water stop valve 23 and disconnect the water inlet 100 from the installation cavity 300. This prevents water from entering the installation cavity 300 and flowing out of the installation hole 400 during the replacement of the scale inhibition core assembly 22, which would cause inconvenience when replacing the scale inhibition mechanism 20.

[0112] Among them, such as Figure 3 and Figure 4 As shown, the valve body 21 is provided with a water inlet 100 and a mounting hole 400 on opposite sides along the first direction, respectively, which can also facilitate the scale inhibition core assembly 22 to drive the water stop valve 23 installed at the water inlet 100 along the first direction.

[0113] like Figure 4 and Figure 5 As shown, by setting the connecting groove 803 and the protrusion 211, the position stability of the scale inhibition core assembly 22 relative to the valve body 21 is ensured, thereby ensuring the stability of the scale inhibition core assembly 22 driving the water stop valve 23 and ensuring the stability of the connection between the water inlet 100 and the installation cavity 300.

[0114] In the exemplary embodiment, please combine Figures 10 to 12 The water stop valve 23 includes a valve core 231 and a reset member 232. The valve core 231 is movably mounted on the water inlet 100 and is capable of moving relative to the valve body 21 in a first direction parallel to the first flow hole 801. The movement path of the valve core 231 is axially eccentric with the first flow hole 801 and is located circumferentially outside the first flow hole 801. This prevents the valve core 231 from blocking the first flow hole 801 when the scale inhibition core assembly 22 is driven, ensuring that water can smoothly enter the first flow hole 801. In the disclosed embodiment, the reset member 232 is a spring.

[0115] The valve core 231 is configured to move relative to the valve body 21 in a direction parallel to the first direction under the drive of the scale inhibition core assembly 22 , connecting the water inlet 100 with the installation cavity 300 , and enabling the reset member 232 to generate a driving force to reset the valve core 231 .

[0116] In the embodiment of the present disclosure, the water inlet 100 is axially eccentrically arranged relative to the first flow hole 801. The moving path of the valve core 231 is coaxially arranged with the water inlet 100. The valve core 231 has a sealing member 2311, and the sealing member 2311 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 assembly errors between the water stop valve 23 and the valve body 21, which causes the sealing member 2311 to be unable to cooperate with the valve body 21 to disconnect the water inlet 100 and the installation cavity 300, the water stop valve 23 is also provided with an outer shell 233. The outer shell 233 is installed at the water inlet 100 and is fixedly connected to the valve body 21.

[0117] Driven by the scale inhibition core assembly 22, the valve core 231 moves relative to the valve body 21 in a direction parallel to the first direction, and then relative to the outer shell 233, allowing the circumferential outer side of the seal 2311 to separate from the inner wall of the outer shell 233, thereby connecting the water inlet 100 with the installation cavity 300. The reset member 232 can be disposed between the valve core 231 and the outer shell 233 and is compressed by the valve core 231 toward the outer shell 233, generating a driving force to reset the valve core 231. The scale inhibition core assembly 22 separates from the valve core 231, and the valve core 231 is reset by the reset member 232, allowing the circumferential outer side of the seal 2311 to engage the inner wall of the outer shell 233, thereby disconnecting the water inlet 100 from the installation cavity 300. The outer shell 233 is a detachable structure and can include a main body 2331 and a cover 2332 to facilitate installation of the valve core 231 and the reset member 232. The valve core 231 can be slidably connected to at least one of the main body 2331 and the cover 2332. The cover 2332 is provided with an opening 900 to allow water to enter the water inlet 100.
