[0054] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0055] like Figure 1 , Figure 2 As shown, as one aspect of the embodiments of this application, this embodiment provides a water treatment device, including a housing 1 and a scale inhibition component 2.

[0056] The housing 1 includes a first water inlet 11 and a second water inlet 12. The first water inlet 11 and the second water inlet 12 can serve as the water inlet and water outlet of the housing 1, respectively. The specific port of the first water inlet 11 and the second water inlet 12 that serves as the water inlet can be selected as needed and is not specifically limited here. It should be understood that each of the first water inlets 11 and the second water inlets 12 described in the following embodiments can be understood as either a water inlet or a water outlet. For example, when the first water inlet 11 serves as the water inlet of the housing 1, the second water inlet 12 serves as the water outlet of the housing 1. Or, when the first water inlet 11 serves as the water outlet of the housing 1, the second water inlet 12 serves as the water inlet of the housing 1.

[0057] It should be noted that the shape, size, and positions of the first water inlet 11 and the second water inlet 12 of the housing 1 can be selected and adjusted as needed, and are not specifically limited here. The housing 1 is mainly used to contain water to be flowed into the water-using equipment. The water-using equipment described in the embodiments of this application can be understood as any domestic water-using device used in people's daily lives, and is not specifically limited here. For example, water-using equipment may include water-using equipment in the gas field, kitchen water-using equipment, drinking water equipment, medical cleaning equipment, etc.

[0058] The scale inhibition component 2 is used to descale the water flowing into the housing 1. The scale inhibition component 2 includes an electronic anode 21, which is inserted into the housing 1. When energized, the electronic anode 21 releases hydroxide ions (OH-) which react with bicarbonate ions (HCO3-) in the water to produce carbonate ions (CO3-). The carbonate ions (CO32-) then react with calcium ions (Ca2+) and magnesium ions (Mg2+) to form calcium carbonate (CaCO3) and magnesium carbonate (MgCO3) precipitates. Because this embodiment includes the electronic anode 21, it can soften the water, remove calcium and magnesium ions, and effectively descale the water entering the housing 1, thus effectively reducing scale formation in valves, pipes, and even water-using equipment connected to the water treatment device.

[0059] The scale inhibition assembly 2 also includes a water-passing mesh 22. The water-passing mesh 22 is disposed within the housing 1 and is fitted over the outside of the electron anode 21. The first water inlet 11 communicates with the second water inlet 12 through a flow channel formed between the water-passing mesh 22 and the electron anode 21. This ensures that water flowing into the housing 1 through either the first or second water inlet 12 can contact the electron anode 21 for scale removal. When the electron cathode 23 is energized, the water-passing mesh 22 allows precipitates (e.g., positively charged calcium and magnesium ions) from the electron anode 21 to be adsorbed onto the mesh, preventing the precipitates from flowing out of the housing 1 along with the water, thereby achieving the purpose of removing scale formation in the water. In this embodiment, because the water-passing mesh 22 is fitted over the electron anode 21, it can prevent the precipitated scale from flowing out of the housing 1.

[0060] The shape, structure, and size of the water filter 22 can be selected and adjusted according to the shape, structure, and size of the housing 1. The material of the water filter 22 can be selected and adjusted according to the structure of the sterilization component 5 and / or the scale inhibition component 2. No specific limitations are made here.

[0061] In one example, the water filter 22 is made of stainless steel to facilitate scale adsorption and prevent corrosion.

[0062] In one example, the water filter 22 is detachably disposed within the housing 1 so that it can be cleaned promptly when excessive scale accumulates on it. To facilitate timely cleaning of the scale adsorbed on the water filter 22, the housing 1 can be made transparent or translucent.

[0063] In one embodiment, the scale inhibition assembly 2 further includes an electron cathode 23, which is inserted into the housing 1 and extends into the interior of the housing 1. The electron cathode 23 and electron anode 21 are connected to a power source. The electron cathode 23 is also connected to a water filter 22. An applied current causes cathodic polarization of the water filter 22, thereby enabling the water filter 22 to adsorb scale (calcium carbonate (CaCO3) and magnesium carbonate (MgCO3) precipitates) formed in the water. Furthermore, the electrochemical protection provided by the water filter 22 prevents corrosion of the interior of the housing 1.

[0064] The electron cathode 23 can be directly connected to the water filter 22, or it can be connected to the water filter 22 through a conductor, or it can be connected to the water filter 22 through a water medium. The specific implementation method can be selected and adjusted as needed, as long as the water filter 22 can adsorb the scale precipitated from the electron anode 21.

[0065] In one example, the electron cathode 23 is a conductive sheet.

[0066] In one example, an anode lead-out and a cathode lead-out are also included, the anode lead-out being connected to the electron anode 21 and the cathode lead-out being connected to the electron cathode 23. The anode lead-out and cathode lead-out are used to connect to a power source to supply power to the electron anode 21 and the electron cathode 23.

[0067] In one example, the portion of the electronic anode 21 extending to the outer side of the top of the housing can serve as the anode lead-out. The portion of the electronic cathode 23 extending to the outer side of the top of the housing can serve as the cathode lead-out.

[0068] In one implementation, such as Figure 1 , Figure 2 As shown, the housing 1 includes an end cap 13 and a cup body 14 connected to each other. A first water inlet 11 and a second water inlet 12 are formed on the end cap 13. The flow direction of water flowing through the inside of the cup body 14 and the first water inlet 11 is opposite to the flow direction of water flowing through the inside of the cup body 14 and the second water inlet 12. The shape, structure, size, and material of the end cap 13 and the cup body 14 can be selected and adjusted as needed, and are not specifically limited here.

[0069] In one embodiment, the cup body 14 has a structure with one end open and the other end closed. The end cap 13 is detachably connected to the open end of the cup body 14. Because the cup body 14 and the end cap 13 are detachably connected, it is convenient to clean the inside of the cup body 14, as well as to replace and maintain the sterilization component 5 and the descaling component in the cup body 14.

[0070] In one example, to improve the sealing between the cup body 14 and the end cap 13, a sealing ring 15 can be provided between the cup body 14 and the end cap 13.

[0071] In one example, to facilitate observation of the water quality in the inner cavity of the housing 1, the operation of the sterilization component 5 and the scale inhibition component 2, the cup body 14 may be made of a transparent or translucent material.

[0072] In one embodiment, to more effectively descale the water in the housing 1, the electron anode 21 can be inserted into the end cap 13 and extend to the bottom of the cup body 14. This allows for effective descaling of the water in all locations within the cup body 14, evenly distributed along its height.

[0073] In one example, the water filter 22 is disposed between the inner bottom surface of the cup body 14 and the inner top surface of the end cap 13. Specifically, one end of the water filter 22 contacts the inner bottom surface of the cup body 14, and the other end of the water filter 22 contacts the inner top surface of the end cap 13, so that the water filter 22 can be stably disposed in the housing 1 and will not be loosened or fall off due to the water flow in the housing 1.

[0074] In one embodiment, the water-passing mesh 22 adopts a cylindrical structure, and multiple water-passing holes 221 are provided on the cylindrical wall. The internal space enclosed by the water-passing mesh 22 is connected to the internal space of the outer shell 1 of the water-passing mesh 22 through the water-passing holes 221, so that water can flow into the water-passing mesh 22 through the water-passing holes 221 and come into contact with the electron anode 21.

[0075] In one embodiment, the first water inlet 11 on the end cap 13 serves as a water inlet, and the first water inlet 11 connects to the annular space between the outer wall of the water mesh 22 and the inner wall of the cup body 14. The second water inlet 12 on the end cap 13 serves as a water outlet, and the second water inlet 12 connects to the interior of the water mesh 22. The interior of the water mesh 22 communicates with the exterior of the water mesh 22 through water passage holes 221. Thus, when water enters the cup body 14 from the first water inlet 11, the water flows into the interior of the water mesh 22 through the water passage holes 221 and contacts the electron anode 21, and then flows out from the second water inlet 12 through the top of the interior of the water mesh 22.

[0076] In one embodiment, the second water inlet 12 on the end cap 13 serves as a water inlet, and the second water inlet 12 connects to the annular space between the outer wall of the water mesh 22 and the inner wall of the cup body 14. The first water inlet 11 on the end cap 13 serves as a water outlet, and the first water inlet 11 connects to the interior of the water mesh 22. The interior of the water mesh 22 communicates with the exterior of the water mesh 22 through water passage holes 221. Thus, when water enters the cup body 14 from the second water inlet 12, the water flows into the interior of the water mesh 22 through the water passage holes 221, contacts the electron anode 21, and flows out from the first water inlet 11 through the top of the interior of the water mesh 22.

[0077] In one embodiment, the end cap 13 may also be provided with a third water inlet 33, which can serve as a backup water inlet, and its use can be determined when connecting to different devices. When it is not needed, it can be sealed with a plug.

[0078] In one embodiment, the water treatment apparatus further includes a water supply pipe for connection to a water-using device, the water supply pipe being connected to a first water inlet 11 and / or a second water inlet 12.

[0079] In one example, when the water supply pipe of the water-using equipment is the inlet pipe, the first water inlet 11 is the inlet, and the second water inlet 12 is the outlet, the inlet pipe of the water-using equipment can be connected to the second water inlet 12, and the first water inlet 11 can be connected to an external water source pipeline. This connection method allows the scale inhibitor 2 to descale the water supplied by the external water source pipeline, and then delivers the descaled water to the inlet pipe of the water-using equipment for its use. This effectively reduces the problem of scale residue in the water-using equipment and its inlet pipe, and addresses the issue of excessive scale buildup affecting the water supply efficiency of the inlet pipe and the performance of the water-using equipment.

[0080] In one example, when the water supply pipe of the water-using device is the outlet pipe, the first water inlet 11 is the inlet, and the second water inlet 12 is the outlet, the outlet pipe of the water-using device can be connected to the first water inlet 11, and the second water inlet 12 can be connected to the user's water supply line. This connection method allows the scale inhibitor component 2 to descale the water flowing from the water-using device, and then delivers the descaled water to the user's water supply line for use. This improves the user's water quality, preventing scale from adhering to the user's skin or entering the user's body when drinking, thus making the user's water use safer and healthier.

[0081] In one embodiment, the water treatment device further includes a thermostatic valve 3 for connection to a water-using device. The inlet 31 of the thermostatic valve 3 can be connected to a first water inlet 11 and / or a second water inlet 12. The thermostatic valve 3 is used to adjust the outlet water temperature of the water-using device by changing the mixing volume of cold and hot water. The scale inhibitor assembly 2 is used to descale the water flowing into the water-using device via the thermostatic valve 3.

[0082] In one example, such as Figures 1 to 3As shown, the thermostatic valve 3 in various embodiments of this application includes at least an inlet 31, an outlet 32, a third inlet 33, and a fourth inlet 34. When the first inlet 11 is the inlet, one end of the inlet 31 of the thermostatic valve 3 is connected to the first inlet 11 for inputting descaled water from the housing 1 into the thermostatic valve 3. The other end of the inlet 31 of the thermostatic valve 3 is connected to the third inlet 33 for inputting externally input cold water into the water-using equipment via the third inlet 33. The other end of the inlet 31 of the thermostatic valve 3 is also connected to the mixing chamber of the thermostatic valve 3 for inputting cold water into the mixing chamber to adjust the temperature of the hot water supplied to the mixing chamber by the water-using equipment via the fourth inlet 34. One end of the fourth inlet 34 is connected to the hot water outlet of the water-using equipment, and the other end of the fourth inlet 34 is connected to the mixing chamber, for inputting hot water heated by the water-using equipment into the mixing chamber of the thermostatic valve 3. The outlet 32 ​​of the thermostatic valve 3 is connected to the mixing chamber, and is used to deliver water that has been temperature-regulated by the mixing chamber to the user. The mixing chamber is equipped with a flow regulating mechanism, which is used to regulate the flow rate of hot water flowing into the mixing chamber from the fourth water inlet 34, and to regulate the flow rate of cold water flowing into the mixing chamber from the inlet 31 of the thermostatic valve 3, thereby regulating the temperature of the water in the mixing chamber that is about to flow into the outlet 32 ​​of the thermostatic valve 3.

[0083] The water treatment device of this embodiment has a thermostatic valve 3 and a scale inhibitor 2, and the scale inhibitor 2 is located at the inlet 31 of the thermostatic valve 3. Therefore, after the water treatment device is connected to the water-using equipment or water heater, it can not only adjust the outlet water temperature of the water-using equipment or water heater, but also effectively remove scale from the water flowing into the water-using equipment or water heater.

[0084] In one specific implementation, such as Figure 3As shown, the mixing chamber of the thermostatic valve 3 is connected to the pipeline forming the inlet 31 and the third outlet 33 of the thermostatic valve 3 via a retaining ring 35 and a sealing ring 231. The inlet 31 of the thermostatic valve 3 is connected to the outlet (first outlet 11 or second outlet 12) of the end cap 13. The end cap 13 is detachably connected to the cup body 14, and a scale inhibitor 2 is provided in the cup body 14. The electronic anode 21 is inserted into the cup body 14 through the end cap 13. A temperature sensor 37 and a water flow sensor 38 for measuring the inlet water temperature are provided at the inlet (first outlet 11 or second outlet 12) of the end cap 13. The mixing chamber of the thermostatic valve 3 is connected to the pipeline forming the outlet 32 ​​and the fourth outlet 34 of the thermostatic valve 3 via a retaining ring 35 and a sealing ring 231. A temperature sensor 37 for measuring the outlet water temperature is provided at the fourth outlet 34. A bushing 39, made of PTFE, is inserted into the mixing chamber of the thermostatic valve 3. An adjusting valve core 40 is housed inside the bushing 39. The sealing between the adjusting valve core 40 and the mixing chamber is achieved through an interference fit with the bushing 39, thus providing both sealing and lubrication. The adjusting valve core 40 is connected to the output end of the motor 42 via a mounting plate 41. Driven by the motor 42, the adjusting valve core 40 can be rotated to adjust the opening degree of the mixing chamber, the inlet 31 of the thermostatic valve 3, and the fourth outlet 34.

[0085] In one implementation, such as Figure 4 , Figure 5 As shown, the water treatment device may also include a sterilization component 5. This component is disposed within the housing 1 and is used to sterilize the water flowing through the housing 1. The sterilization component 5 includes a sterilization lamp 51, which is inserted into the housing 1.

[0086] The germicidal lamp 51 can adopt any structure of germicidal lamp 51 in the prior art, and no specific limitation is made here. As long as it can destroy the DNA base pairs of bacteria in the water when irradiated, so that the bacterial cells lose their ability to replicate and reproduce, or even die, it is acceptable. For example, the germicidal lamp 51 can be an ultraviolet lamp or a mercury lamp.

[0087] When the germicidal lamp 51 uses an ultraviolet lamp, the wavelength range of the ultraviolet light emitted by the ultraviolet lamp is from 200nm to 275nm. Ultraviolet light within this wavelength range can effectively kill bacteria in the water.

[0088] In this embodiment, since both the scale inhibition component 2 and the sterilization component 5 are installed in the housing 1, the water flowing through the housing 1 can be sterilized and disinfected as well as descaled. This improves water quality and enhances the safety of water used by users.

[0089] In one example, the location of the sterilization component 5 within the housing 1 can be selected and adjusted as needed. For instance, the sterilization component 5 can be located inside the area enclosed by the water-passing mesh 22. Alternatively, the sterilization component 5 can be located outside the water-passing mesh 22.

[0090] In one embodiment, the germicidal lamp 51 of the sterilization component 5 is inserted into the housing 1 and located between the outer wall of the water-passing mesh 22 and the inner wall of the housing 1.

[0091] In another embodiment, the germicidal lamp 51 of the sterilization component 5 is disposed in the water-passing net 22, and the germicidal lamp 51 is spaced apart from the electronic anode 21.

[0092] In one implementation, such as Figures 4 to 6 As shown, a light shield 6 is fitted around the outside of the germicidal lamp 51. An annular flow channel is formed between the inner wall of the light shield 6 and the outside of the germicidal lamp 51. The top of the annular flow channel is connected to the second water inlet 12, and the bottom of the annular flow channel is connected to the inside of the housing 1. This allows water flowing into the housing 1 to enter the annular flow channel and be irradiated and sterilized by the germicidal lamp 51. The light shield 6 is used to prevent the light from the germicidal lamp 51 from shining into the cup 14 outside the light shield 6, thereby preventing long-term irradiation of the cup 14 from causing corrosion, and also preventing the light from being absorbed by the external environment and reducing the sterilization intensity of the light.

[0093] In one example, the light shield 6 includes a cylindrical body and an opaque reflective layer disposed on the inner wall of the cylindrical body. The opaque reflective layer is used to block the germicidal light emitted by the germicidal lamp 51 from shining onto the inner wall of the housing 1 or being absorbed by the inner wall of the housing 1. Furthermore, the opaque reflective layer can reflect the germicidal light that shines upon it back, thereby allowing the reflected germicidal light to further disinfect the water flowing through the annular channel. Through repeated reflection of the germicidal light, a very strong light field can be formed in the annular channel, effectively improving the sterilization efficiency and quality of the liquid.

[0094] The specific material of the opaque reflective layer can be selected and adjusted according to the type of germicidal light emitted by the germicidal lamp 51. For example, when the germicidal light is ultraviolet light, the opaque reflective layer can be made of aluminum foil. The opaque reflective layer can be a coating formed on the inner wall of the cylinder, or it can be a thin structure covering the inner wall of the cylinder.

[0095] In one embodiment, a light-transmitting cover 7 is disposed inside the light-shielding cover 6, covering the outside of the germicidal lamp 51. An annular flow channel is formed between the outer side of the light-transmitting cover 7 and the inner sidewall of the light-shielding cover 6. The light-transmitting tube is used to isolate the germicidal lamp 51 from the inner cavity of the cup body 14, preventing water flowing into the cup body 14 from directly contacting the germicidal lamp 51 and causing damage to the germicidal lamp 51, and preventing secondary pollution of the water after the germicidal lamp 51 comes into contact with the water.

[0096] In one example, the light-transmitting tube can be made of any material that is non-reflective and does not absorb light. For example, it can be made of quartz glass. Quartz glass is made by melting various pure natural quartz (such as crystal, quartz sand, etc.). It has an extremely small coefficient of linear expansion, only 1 / 10 to 1 / 20 that of ordinary glass, and excellent thermal shock resistance. It has high heat resistance, with a typical operating temperature of 1100–1200 degrees Celsius and a short-term operating temperature up to 1400 degrees Celsius. It also has high spectral transmittance. Quartz glass is an amorphous material composed of a single component, silicon dioxide. Its microstructure is a simple network composed of tetrahedral silicon dioxide structural units. Due to the high Si-O chemical bond energy and the dense structure, quartz glass possesses unique properties, especially transparent quartz glass, which exhibits excellent optical properties and a superior transmittance across a continuous wavelength range from ultraviolet to infrared radiation.

[0097] In one embodiment, the sterilization component 5 further includes a baffle 8, which is disposed between the sterilization lamp 51 and the light shield 6 along the length of the sterilization lamp 51. The baffle 8 is used to change the flow direction and velocity of the water entering the annular flow channel inside the light shield 6, and prolong the residence time of the water entering the annular flow channel, thereby enabling the sterilization lamp 51 to fully sterilize and disinfect the water flowing into the light shield 6.

[0098] In one implementation, such as Figures 4 to 6 As shown, the spoiler 8 adopts a spiral structure, and the spiral structure spoiler 8 is arranged around the outer wall of the light-transmitting cover 7 or the inner wall of the light-transmitting cover 7 along the length direction of the germicidal lamp 51.

[0099] In one example, the spoiler 8 may also be a plurality of fin structures, strip structures or ring structures, etc., spaced apart on the outer side wall or the inner side wall of the light-transmitting cover 7.

[0100] It should be noted that the structure and arrangement of the baffle 8 can be selected and adjusted as needed, and no specific limitation is made here. As long as it can turbulent the water entering and flowing around the germicidal lamp 51 and prolong the time it spends flowing through the area around the germicidal lamp 51, it is acceptable.

[0101] In one embodiment, the germicidal lamp 51 is inserted into the end cap 13 and extends to the bottom of the cup body 14. Since the germicidal lamp 51 is arranged along the height direction of the cup body 14, it can effectively irradiate the water in various positions in the cup body 14, thereby improving the sterilization efficiency.

[0102] It should be noted that, in some examples, the shell 1 mentioned in the embodiments of this application can be understood as specifically referring to the cup body 14, or it can be understood as referring to the entire shell 1 structure including the end cap 13 and the cup body 14. The specific understanding should be based on the accompanying drawings and the context of the embodiments. That is to say, the shell 1 in the embodiments of this application should not be simply understood as only the structure including the end cap 13 and the cup body 14, but may also be understood as the cup body 14 of the shell 1.

[0103] In one example, such as Figures 4 to 7 As shown, the thermostatic valve 3 in various embodiments of this application includes at least an inlet, an outlet, a third inlet 33, and a fourth inlet 34. When the first inlet 11 is the inlet, one end of the inlet 31 of the thermostatic valve 3 is connected to the first inlet 11 to input descaling and sterilizing water from the housing 1 into the thermostatic valve 3. The other end of the inlet 31 of the thermostatic valve 3 is connected to the third inlet 33 to input externally input cold water into the water-using equipment via the third inlet 33. The other end of the inlet 31 of the thermostatic valve 3 is also connected to the mixing chamber of the thermostatic valve 3 to input cold water into the mixing chamber for adjusting the temperature of the hot water supplied to the mixing chamber by the water-using equipment via the fourth inlet 34. One end of the fourth inlet 34 is connected to the hot water outlet of the water-using equipment, and the other end of the fourth inlet 34 is connected to the mixing chamber. The fourth inlet 34 is used to input hot water heated by the water-using equipment into the mixing chamber of the thermostatic valve 3. The outlet 32 ​​of the thermostatic valve 3 is connected to the mixing chamber, and is used to deliver water that has been temperature-regulated by the mixing chamber to the user. The mixing chamber is equipped with a flow regulating mechanism, which is used to regulate the flow rate of hot water flowing into the mixing chamber from the fourth water inlet 34, and to regulate the flow rate of cold water flowing into the mixing chamber from the inlet 31 of the thermostatic valve 3, thereby regulating the temperature of the water in the mixing chamber that is about to flow into the outlet 32 ​​of the thermostatic valve 3.

[0104] The water treatment device of this embodiment has a thermostatic valve 3, a scale inhibition component 2, and a sterilization component 5. The sterilization component 5 and the scale inhibition component 2 are located at the inlet 31 of the thermostatic valve 3. Therefore, after the water treatment device is connected to the water-using equipment or water heater, it can not only adjust the outlet water temperature of the water-using equipment or water heater, but also effectively remove scale and sterilize the water flowing into the water-using equipment or water heater.

[0105] In one specific implementation, such as Figure 7As shown, the mixing chamber of the thermostatic valve 3 is connected to the pipeline forming the inlet 31 and the third outlet 33 of the thermostatic valve 3 via a retaining ring 35 and a sealing ring 231. The inlet 31 of the thermostatic valve 3 is connected to the outlet (first outlet 11 or second outlet 12) of the end cap 13. The end cap 13 is detachably connected to the cup body 14, and the cup body 14 is provided with a scale inhibitor 2. The electronic anode 21 and the germicidal lamp 51 are inserted into the cup body 14 through the end cap 13. A temperature sensor 37 and a water flow sensor 38 for measuring the inlet water temperature are provided at the inlet (first outlet 11 or second outlet 12) of the end cap 13. The mixing chamber of the thermostatic valve 3 is connected to the pipeline forming the outlet 32 ​​and the fourth outlet 34 of the thermostatic valve 3 via a retaining ring 35 and a sealing ring 231. A temperature sensor 37 for measuring the outlet water temperature is provided at the fourth outlet 34. A bushing 39, made of PTFE, is inserted into the mixing chamber of the thermostatic valve 3. An adjusting valve core 40 is housed inside the bushing 39. The sealing between the adjusting valve core 40 and the mixing chamber is achieved through an interference fit with the bushing 39, thus providing both sealing and lubrication. The adjusting valve core 40 is connected to the output end of the motor 42 via a mounting plate 41. Driven by the motor 42, the adjusting valve core 40 can be rotated to adjust the opening degree of the mixing chamber, the inlet 31 of the thermostatic valve 3, and the fourth outlet 34.

[0106] In one specific implementation, such as Figure 6 As shown, the water treatment device includes a cup body 14, which is connected to an end cap 13 via a sealing ring 15. A water filter 22 is inserted into the cup body 14. An electron anode 21 is inserted into the end cap 13 and extends into the cup body 14, and is sealed to the end cap 13 via a sealing ring 231 and a pressure plate. An electron cathode 23 includes a bolt 232 and a nut 233. The bolt 232 is inserted into the end cap 13 and is sealed to the end cap 13 via sealing rings 231 and 231. The bolt 232 and nut 233, extending into the housing 1, are connected to the water filter 22. A light shield 6 is inserted into the water filter 22, and a germicidal lamp 51 is installed in the light shield 6. A spiral baffle 8 is provided between the germicidal lamp 51 and the light shield 6. A shock-absorbing pad 234 is provided at one end of the germicidal lamp 51 near the bottom of the cup body 14 to prevent the germicidal lamp 51 from bumping and being damaged by surrounding devices under the vibration of the cup body 14. A water flow sensor 38 and a temperature sensor 37 are provided on the first water inlet 11 and / or the second water inlet 12 on the end cap 13. A water flow rotor 91 is provided in the first water inlet 11 and / or the second water inlet 12 of the end cap 13, and the water flow rotor 91 is connected to the detection end of the water flow sensor 38.

[0107] In one embodiment, the first water inlet 11 and / or the second water inlet 12 are provided with a water flow sensor 38, which is electrically connected to the electronic anode 21 and / or the germicidal lamp 51, so that the electronic anode 21 and / or the germicidal lamp 51 can determine the working status based on the water flow detection signal of the water flow sensor 38.

[0108] In this embodiment, since a water flow sensor 38 is provided at the first water inlet 11 and / or the second water inlet 12, the germicidal lamp 51 and / or the electronic anode 21 can be turned on only when water flows into the housing 1, and turned off when no water flows into the inner cavity of the housing 1. This allows the germicidal lamp 51 and / or the electronic anode 21 to be used immediately upon activation, achieving energy conservation.

[0109] In one implementation, such as Figure 2 As shown, the water flow sensor 38 includes a water flow rotor 91. The water flow rotor 91 is disposed in the first water inlet 11 and / or the second water inlet 12, and is used to generate eddies in the water entering the inlet pipe and create a magnetic field around it. When the detection unit of the water flow sensor 38 senses a change in the magnetic field around the water flow rotor 91, it sends a water flow detection signal to the germicidal lamp 51 and / or the electronic anode 21, so that the germicidal lamp 51 and / or the electronic anode 21 can be turned on.

[0110] In one embodiment, the water flow rotor 91 may include a plurality of streamlined channels evenly distributed circumferentially, each streamlined channel forming a flow-guiding spiral structure, thereby enabling water passing through the guide section to form a vortex. The water flow rotor 91 also includes an impeller and a support, the support being disposed in the first water inlet 11 and / or the second water inlet 12, and the impeller being rotatably connected to the support. The water flow rotor 91 also includes a Hall switch for detecting the magnetic field around the water flow rotor 91.

[0111] In one embodiment, an indicator light is provided on the outside of the housing 1. The indicator light is electrically connected to the electronic anode 21 and / or the germicidal lamp 51 and is used to control the working state of the light source unit according to the working state of the electronic anode 21 and / or the germicidal lamp 51.

[0112] In one specific embodiment, when only the electronic anode 21 is provided in the housing 1, the electronic anode 21 is turned on when the water flow sensor 38 detects water flow. When the water flow sensor 38 does not detect water flow, the electronic anode 21 is turned off. When the electronic anode 21 is on, the indicator light is constantly lit or flashing to inform the user that the electronic anode 21 is currently working. When the electronic anode 21 is off, the indicator light is off to inform the user that the electronic anode 21 is not currently working. When the water flow sensor 38 detects water flow, but the electronic anode 21 does not turn on, the indicator light is in a warning state to inform the user that the electronic anode 21 is malfunctioning.

[0113] In one specific embodiment, the germicidal lamp 51 is an ultraviolet (UV) lamp. When the water flow sensor 38 detects water flow, the UV lamp and electronic anode 21 are turned on. When the water flow sensor 38 does not detect water flow, the UV lamp and electronic anode 21 are turned off. When the UV lamp and electronic anode 21 are on, the indicator light is constantly lit or flashing to inform the user that the UV lamp and electronic anode 21 are currently working. When the UV lamp and electronic anode 21 are off, the indicator light is off to inform the user that the UV lamp and electronic anode 21 are not currently working. When the water flow sensor 38 detects water flow, but the UV lamp and electronic anode 21 do not turn on, the indicator light is in a warning state to inform the user that the UV lamp and / or electronic anode 21 are malfunctioning. In this embodiment, there can be two indicator lights, each connected to the germicidal lamp 51 and the electronic anode 21 respectively, to display the working status of the germicidal lamp 51 and the electronic anode 21.

[0114] In the above embodiments, when the first water inlet 11 is a water inlet, the second water inlet 12 is a water outlet. When the first water inlet 11 is a water outlet, the second water inlet 12 is a water inlet.

[0115] In one embodiment, a water supply pipe connected to a water-using device is also included, the water supply pipe communicating with a first water inlet 11 and / or a second water inlet 12 on the end cap 13. A sterilization component 5 and / or a scale-inhibiting component 2 are provided in the cup body 14.

[0116] In one embodiment, a thermostatic valve 3 connected to the water-using equipment is also included. The inlet 31 of the thermostatic valve 3 is connected to a first water outlet 11 and / or a second water outlet 12 on the end cap 13. A sterilization component 5 and / or a scale inhibitor component 2 are provided in the cup body 14. The thermostatic valve 3 is used to adjust the outlet water temperature of the water-using equipment by changing the mixing volume of cold water and hot water. The sterilization component 5 and the scale inhibitor component 2 of the water-using equipment are used to disinfect and sterilize the water flowing into the water-using equipment through the thermostatic valve 3. The thermostatic valve 3 in the various embodiments of this application can adopt any thermostatic valve 3 structure in the prior art, and is not specifically limited here. The thermostatic valve 3 used can achieve the adjustment of the outlet water temperature using cold water and hot water. The method of water temperature adjustment by the thermostatic valve 3 can also be selected and adjusted as needed. For example, an electronic thermostatic valve 3 or a mechanical thermostatic valve 3 can be used.

[0117] The water treatment device of this embodiment has a thermostatic valve 3, a sterilization component 5, and a scale inhibition component 2. The sterilization component 5 and the scale inhibition component 2 are located at the inlet 31 of the thermostatic valve 3. Therefore, after the water treatment device is connected to the water-using equipment or water heater, it can not only adjust the outlet water temperature of the water-using equipment or water heater, but also effectively sterilize and disinfect the water flowing into the water-using equipment or water heater and remove scale.

[0118] In one example, the inner cavity of the cup body 14 extends vertically downwards, and the first water inlet 11 and the second water inlet 12 on the end cap 13 are located above the cup body 14. Since the first water inlet 11 and the second water inlet 12 are located above the cup body 14, water entering the cup body 14 from one of the inlets flows along the height of the cup body 14 to the bottom of the inner cavity. As the water level gradually rises to the top of the cup body 14, the water then flows out of the cup body 14 from the other inlet. During this process, because the water flows in and out in opposite directions, the water can contact the germicidal lamp 51 and / or the electronic anode 21 during both the inflow and outflow processes, improving the sterilization and descaling efficiency of the germicidal lamp 51 and the electronic anode 21, allowing for more thorough sterilization and descaling within the cup body 14.

[0119] In one embodiment, the first water inlet 11 and / or the second water inlet 12 of the end cap 13 can be connected to the water inlet 31 of the thermostatic valve 3 or a water supply pipe via quick-connect couplings. The quick-connect couplings can be any quick-connect coupling structure found in the prior art, and are not specifically limited herein.

[0120] In this embodiment, the first water inlet 11 and / or the second water inlet 12 of the end cap 13 are connected to the water inlet 31 or water supply pipe of the thermostatic valve 3 via quick-connect fittings, which allows the housing 1 to be quickly disassembled and assembled with the thermostatic valve 3 or water supply pipe, so as to facilitate the replacement and maintenance of the sterilization component 5, the descaling component and the thermostatic valve 3 in the housing 1.

[0121] In one embodiment, a temperature sensor 37 is provided on the thermostatic valve 3 and / or the scale inhibitor assembly 2.

[0122] As one aspect of this application, this embodiment provides a water-using device, including the water treatment apparatus of any of the above embodiments. The water-using device can be any device in the prior art, and is not specifically limited herein. For example, the water-using device may include a water heater, a wall-hung boiler, a faucet, a water purifier, a water dispenser, etc.

[0123] In one embodiment, the water treatment device can be installed on the cold water inlet pipe of the water-using equipment. Alternatively, it can be installed on the hot water outlet pipe of the water-using equipment.

[0124] As one aspect of this application, this embodiment provides a thermostatic valve assembly, including a thermostatic valve and the water treatment device of any of the above embodiments. The inlet of the thermostatic valve is connected to the first water inlet and / or the second water inlet of the housing.

[0125] As one aspect of this application, this embodiment provides a water circuit, including a water supply pipe, a thermostatic valve, and the water treatment device of any of the above embodiments. The inlet end of the water supply pipe is connected to the second water outlet of the housing, the first outlet end of the water supply pipe is connected to the mixing chamber of the thermostatic valve, and the second outlet end of the water supply pipe is used to connect to the inlet of a water-using device. The second water outlet is the outlet of the housing, and the water-using device can be understood as a water heater, wall-hung boiler, faucet, water purifier, water dispenser, etc.

[0126] As one aspect of this application, this embodiment provides a water heater, including a water heater body and the water circuit described in the above embodiment. The cold water inlet pipe of the water heater body is connected to the second outlet end of the water supply pipe, and the hot water outlet pipe of the water heater body is connected to the mixing chamber of the thermostatic valve.

[0127] In one example, the water heater can be a gas water heater or an electric water heater.

[0128] In one example, the water heater also includes an anti-electric shock enclosure. The anti-electric shock enclosure is located on the bottom outer side of the water heater body. The water supply pipe, thermostatic valve, and water treatment device are all housed within the anti-electric shock enclosure.

[0129] In one example, such as Figure 8 As shown, the water heater body 400 includes an outer shell 403, an inner tank 404, a heating element 405, a cold water inlet pipe 402, a hot water outlet pipe 406, and an anti-electric shock wall cover 401. The inner tank 404 is housed within the outer shell 403, the heating element 405 is housed within the inner tank 404, and the inlet pipe 402 and outlet pipe 406 are respectively inserted into the inner tank 404. The anti-electric shock wall cover 401 is located on the bottom outer side of the water heater body 400. The water treatment device 100 is mounted between the water heater body 400 and the anti-electric shock wall cover 401 via a mounting bracket 407. The water supply pipe 200, the thermostatic valve 3, and the water treatment device 100 are all housed within the anti-electric shock wall cover 401.

[0130] In one example, the lower half of the housing's cup extends to the outer bottom of the anti-electric shock wall cover. The cup is made of a transparent or semi-transparent material. Because the cup is made of a transparent or semi-transparent material and extends to the outside of the anti-electric shock wall cover, users can observe the scale buildup on the water filter inside the housing in real time, and can promptly disassemble and clean it when excessive scale buildup occurs.

[0131] In one example, the water treatment unit is connected to the interior of the anti-electric shock enclosure and the exterior of the water heater body via a mounting bracket to ensure a secure connection.

[0132] In this embodiment, since the water treatment device is located outside the water heater body, it is convenient to repair and disassemble the scale inhibition component and the sterilization component in the water treatment device. This avoids the problem that it is inconvenient to disassemble and reassemble if the scale inhibition component and the sterilization component are located inside the water heater body if they are damaged.

[0133] In one embodiment, the first and / or second water inlet of the water treatment device can be connected to the cold water inlet pipe of the water heater. Alternatively, the first and / or second water inlet of the water treatment device can be connected to the hot water outlet pipe of the water heater.

[0134] In one embodiment, the water supply pipe of the water treatment device can be connected to the cold water inlet pipe of the water heater. Alternatively, the water supply pipe of the water treatment device can be connected to the hot water outlet pipe of the water heater.

[0135] In one embodiment, the third water inlet of the thermostatic valve of the water treatment device can be connected to the cold water inlet pipe of the water heater, the fourth water inlet of the thermostatic valve can be connected to the hot water outlet pipe of the water heater, the outlet of the thermostatic valve can be connected to the user's water supply side pipe, and the inlet of the thermostatic valve is connected to the first water inlet and / or the second water inlet.
