Description

Technical Field

[0001] This invention belongs to the field of household appliance technology, and in particular relates to a water softener with microbubble function. Background Technology

[0002] Shower heads are common bathing equipment. Typically, shower heads can be connected to the outlet of a mixing valve via a hose or connecting rod, and the water output from the mixing valve ultimately comes out from the shower head.

[0003] To improve water quality in users' homes, it is usually necessary to soften the water in the water supply network. For example, Chinese Patent Publication No. CN 212334812 U discloses a shower water purifier, which is equipped with a filter element. The filter element filters the water flow and needs to be used in conjunction with a switching valve. The filter element and the water valve are housed in the outer casing. At the same time, to improve the bathing experience, a microbubble generator is usually installed in the shower head.

[0004] As usage time increases, filter cartridges need to be replaced periodically. This requires opening the outer casing to replace the cartridges, exposing the valves and connecting water pipes inside. Replacing the valve cartridges can easily damage these components, affecting reliability. Similarly, the microbubble generator in the showerhead is difficult to repair if damaged. Therefore, designing a technology that integrates functions and improves reliability is the technical problem this invention aims to solve. Summary of the Invention

[0005] This invention provides a water softener with microbubble function, which protects the water valve module by shielding it with a liner to improve reliability; at the same time, the microbubble function is integrated into the water softener to facilitate later maintenance.

[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0007] A water softener with microbubble function includes:

[0008] The housing has a liner inside and an openable maintenance cover on the housing.

[0009] Water valve module;

[0010] A water treatment filter element, which is used to treat the water flowing through it;

[0011] A salt tank, wherein the salt tank is equipped with a suction tube;

[0012] A microbubble generator, comprising a throat and a sintered filter element disposed at the throat of the throat, wherein air can enter the throat through the micro-gap of the sintered filter element and mix with water to form microbubble water;

[0013] Water inlet pipe;

[0014] Water outlet pipe;

[0015] Waste discharge pipe;

[0016] The water valve module, the water treatment filter element, and the salt tank are located within the housing, and the liner covers the water valve module. The inlet pipe, the outlet pipe, the water treatment filter element, and the suction pipe are respectively connected to the water valve module. The water valve module is used to selectively control the flow path between the inlet pipe, the water treatment filter element, and the outlet pipe. The water valve module is also used to selectively control the flow path between the inlet pipe, the water treatment filter element, the suction pipe, and the waste discharge pipe. The throat pipe is connected to the outlet pipe.

[0017] By incorporating a liner within the housing, the water valve module, located inside the housing, is concealed from the front. This allows for easy replacement of the water treatment filter cartridge during maintenance; after the inspection cover is removed, the filter cartridge is exposed, facilitating replacement. The water valve module, however, is protected by the liner during maintenance, improving reliability. Furthermore, the liner optimizes the appearance of the water valve module and its connected pipes, ensuring a clean and streamlined look after the inspection cover is removed, thus enhancing product quality.

[0018] Furthermore, integrating the microbubble generator onto the water outlet pipe facilitates integrated design and streamlines maintenance. By incorporating a sintered filter element at the throat of the water outlet, air enters through the micropores of the filter element and mixes with the water. The small size of these micropores allows for air shearing, transforming the air into higher-pressure, finer particles. This results in a more effective and continuous generation of microbubble water. Additionally, the throat structure increases water flow rate and lowers pressure, which, combined with the micropores of the sintered filter element, creates higher air pressure. This allows for greater and easier integration of air into the water, resulting in 10⁶ bubbles per milliliter of microbubble water, further enhancing its effectiveness.

[0019] In one embodiment of this application, the water inlet pipe includes a tee pipe, a filter screen, and a plug. The tee pipe has a water inlet port, an installation port, and a water outlet port. The water inlet port and the installation port are arranged laterally back to back. The water inlet port extends to the outside of the housing. The filter screen is inserted into the tee pipe through the installation port and covers the water outlet port. The water outlet port is connected to the water inlet interface. The plug is detachably disposed in the installation port.

[0020] The liner is provided with a first inspection port, and the water inlet is located in the first inspection port.

[0021] In one embodiment of this application, the microbubble generator includes a first pipe and a second pipe with one end sealed inside the first pipe. The throat is formed between the first pipe, the second pipe, and the sintered filter element. The second pipe is connected to the water outlet.

[0022] In one embodiment of this application, the water outlet pipe is provided with a rotatable locking component;

[0023] The liner is provided with a second inspection port, which is arranged opposite to the locking component.

[0024] In one embodiment of this application, the second inspection port is a flared structure, and the size of the flared structure gradually decreases toward the locking component.

[0025] In one embodiment of this application, the first pipe is provided with a first liquid channel, and the end of the first liquid channel near the second pipe includes a first diameter-changing section, the diameter of the first diameter-changing section gradually decreasing along the direction pointing to the second pipe;

[0026] The second pipe is provided with a second liquid channel. The end of the second liquid channel near the first liquid channel includes a second variable diameter section. Along the direction pointing to the first pipe, the diameter of the second variable diameter section gradually decreases. The sintered filter element is disposed between the first variable diameter section and the second variable diameter section.

The housing is provided with an inlet, an outlet, a suction port, and a return port. A functional flow channel is provided in the housing, the functional flow channel having a shrinking section, an expansion section, and a drainage section. The shrinking section is connected to the expansion section to form a negative pressure zone, and the drainage section is connected to the negative pressure zone. The regeneration valve core is used to control the shrinking section to selectively connect to the inlet, and the regeneration valve core is also used to control the expansion section to selectively connect to the outlet.

[0029] The water inlet is connected to the water inlet pipe, the liquid outlet is connected to the water inlet hole of the water treatment filter element, the liquid return port is connected to the water outlet hole of the water treatment filter element, and the liquid suction port is connected to the liquid suction pipe.

[0030] In one embodiment of this application, the regeneration valve core includes:

In addition, examples of various specific processes and materials are provided in this invention, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0062] Example 1, as Figures 1-6 and Figure 16 As shown, the water softener with microbubble function provided in this application includes:

[0063] The housing 100 has a liner 101 inside and an openable maintenance cover 102 on the housing 100.

[0064] Water valve module 200;

[0065] Water treatment filter element 3, which is used to treat the water flowing through it;

[0066] Salt tank 5, wherein a suction tube (unmarked) is provided in the salt tank;

[0067] A microbubble generator 600 includes a throat and a sintered filter element 61 disposed at the throat of the throat. Air can enter the throat through the micro-gap of the sintered filter element 61 and mix with water to form microbubble water.

[0068] 300mm water inlet pipe;

[0069] Water outlet pipe 400;

[0070] Waste discharge pipe (unmarked);

[0071] The water valve module 200, the water treatment filter element, and the salt tank are located in the housing 100, and the liner 101 covers the water valve module 200. The inlet pipe 300, the outlet pipe 400, the water treatment filter element, and the suction pipe are respectively connected to the water valve module 200. The water valve module 200 is used to selectively control the flow path between the inlet pipe 300, the water treatment filter element, and the outlet pipe 400. The water valve module 200 is also used to selectively control the flow path between the inlet pipe 300, the water treatment filter element, the suction pipe, and the waste discharge pipe. The outlet of the outlet pipe 400 is connected to the microbubble generator 600 and communicates with the throat pipe.

[0072] Specifically, during assembly, the water valve module 200, the water treatment filter element, and the salt tank are all installed inside the housing 100. Then, the inspection cover 102 is closed to complete the assembly. When it is necessary to replace the water treatment filter element, the inspection cover 102 is opened to expose the water treatment filter element, and then the water treatment filter element can be disassembled.

[0073] During the disassembly and assembly of the water treatment filter element, the water valve module 200 is covered by the liner 101, which can reduce the impact of maintenance tools on the water valve module 200 during the disassembly and assembly process. In addition, the liner 101 helps to protect the water pipes and other components on the water valve module 200.

[0074] By incorporating a liner within the housing, the water valve module, located inside the housing, is concealed from the front. This allows for easy replacement of the water treatment filter cartridge during maintenance; after the inspection cover is removed, the filter cartridge is exposed, facilitating replacement. The water valve module, however, is protected by the liner during maintenance, improving reliability. Furthermore, the liner optimizes the appearance of the water valve module and its connected pipes, ensuring a clean and streamlined look after the inspection cover is removed, thus enhancing product quality.

[0075] Water flowing from the outlet pipe 400 enters the throat pipe, flows through it, and is processed by the sintered filter element 1. Due to the micro-pore structure of the sintered filter element 61, air can enter the throat pipe through these micro-pores and mix with the water. Because the micro-pores of the sintered filter element 61 are small, they can shear the air, transforming it into finer, higher-pressure air. Combined with the throat pipe structure, this increases the water flow rate and decreases the pressure. The higher-pressure finer air further facilitates the incorporation of more air into the water, resulting in microbubble water containing 10⁶ bubbles per milliliter. This produces better microbubble water and allows for continuous generation. Furthermore, the microbubble generator of this invention, at 0.3 MPa, produces microbubble water with a bubble diameter of 47 micrometers, which is smaller than the bubble size produced by existing bubble generators, resulting in superior cleaning performance.

[0076] To better illustrate the above principles, the microbubble generator will be described below with a specific structural explanation.

[0077] like Figure 17 As shown, the microbubble generator includes a sintered filter element 61, a first pipe 62, a second pipe 63, and a gas pipe 64, wherein:

[0078] One end of the second pipe 63 is sealed inside the first pipe 62, and the two pipes together form the throat with the sintered filter element 61. The sintered filter element 61 is disposed at the throat of the throat. For example, a first liquid channel 621 is provided inside the first pipe 62. The end of the first liquid channel 621 near the second pipe 63 includes a first diameter-reducing section, and the diameter of the first diameter-reducing section gradually decreases along the direction pointing towards the second pipe 63. A second liquid channel 631 is provided in the second pipe 63. The end of the second liquid channel 631 near the first liquid channel 621 includes a second diameter-reducing section, and the diameter of the second diameter-reducing section gradually decreases along the direction pointing towards the first pipe 62. The sintered filter element 61 is disposed between the first diameter-reducing section and the second diameter-reducing section. Through this structure, the first liquid channel 621, the sintered filter element 61, and the second liquid channel 631 together form the throat structure. When water is introduced, the throat can generate an adsorption force to draw air into the micro gaps between the sintered filter elements 61, and the air is sheared into finer and higher pressure air by the micro gaps, which then mixes with water to form microbubble water.

[0079] A gas communication hole 622 is provided on the first pipe 62, which is positioned directly opposite the sintered filter element 61. Through this gas communication hole 622, outside air can flow to the sintered filter element 61 and then enter the throat tube through the micro-gap of the sintered filter element 61. In addition, the gas pipe 64 in this embodiment can be threaded to the gas communication hole 622. A gas channel is provided in the gas pipe 64, which is connected to the gas communication hole 622. Outside air enters the gas communication hole 622 through the gas channel and then enters the micro-gap of the sintered filter element 61.

[0080] It should be noted that in this embodiment, the gas pipeline 64 can also be connected to the gas pump 610 (e.g., Figure 17 As shown, an air source capable of delivering air can increase air pressure. When combined with a throat tube, the sheared air can enter the throat tube at a higher pressure and mix with water, resulting in a better effect of forming microbubble water.

[0081] Preferably, one end of the second pipe 63 is fixedly connected to the first pipe 62 by bolts. Specifically, flange structures can be provided on the first pipe 62 and the second pipe 63, and then the first pipe 62 and the second pipe 63 are fixed by bolts and flange structures. The second pipe 63 can also be fixed by other methods such as threaded connection.

[0082] In this embodiment, a rubber gasket 65 is provided between the sintered filter element 61 and the first pipe 62. This rubber gasket 65 prevents water flow from impacting the sintered filter element 61 and causing damage. The water pressure is buffered by the rubber gasket 65 and does not directly act on the end face of the sintered filter element 61, thus effectively protecting it. Furthermore, the rubber gasket 65 also prevents the sintered filter element 61 from being damaged by impact or pressure during the assembly of the microbubble generator in this embodiment.

[0083] For reference Figure 17 and Figure 18 The microbubble generator in this embodiment also includes a third pipe 66, which is sealed to the end of the first pipe 62 away from the sintered filter element 61. The third pipe 66 has a third liquid channel 661 that communicates with the first liquid channel 22. An inlet 662 communicating with the third liquid channel 661 is provided on the third pipe 66, allowing water to enter the third liquid channel 661 through the inlet 662 and then enter the first liquid channel 22. In this embodiment, one end of the third pipe 66 is placed inside the first pipe 62, and the two are fixedly connected by a flange and bolts, with a sealing ring between them for sealing.

[0084] like Figure 17As shown, the microbubble generator in this embodiment also includes a bypass pipe 67, which, exemplarily, connects to both sides of the throat of the throat tube. By providing the bypass pipe 67, water can flow through the throat of the throat tube and mix with fine air to form microbubble water, while another portion mixes with the formed microbubble water, thereby changing the bubble content in the microbubble water flowing out of the outlet. In this embodiment, one end of the bypass pipe 67 is connected to the inlet 662 of the third pipe 66, and the other end is connected to the second pipe 63 (… Figure 18 As shown, the second pipe 63 has a connecting hole 632 that connects to the second liquid channel 631, and the bypass pipe 67 is sealed and connected to the connecting hole 632. In this embodiment, the diameter of the bypass pipe 67 is larger than the maximum diameter of the throat pipe.

[0085] To better achieve stepless adjustment of the bubble content in the microbubble water flowing out of the outlet, the microbubble generator in this embodiment also includes a distribution valve 68. The inlet of the distribution valve 68 is connected to the inlet 662 of the third pipe 66, and it has two outlets, respectively connected to the bypass pipe 67 and the third liquid channel 661. Through the distribution valve 68, the ratio of water entering the bypass pipe 67 and the third liquid channel 661 can be adjusted, thereby changing the bubble content of the microbubble water formed in the throat of the throat. Furthermore, by mixing the water in the bypass pipe 67 with the microbubble water formed in the second liquid channel 631, the bubble content of the final microbubble water can be adjusted to meet the requirements of different users. In addition, by setting the distribution valve 68, this embodiment can adjust the pressure of the water entering the throat, thereby preventing excessive water pressure from preventing air from effectively dissolving, thus further increasing the probability of microbubble water generation. The aforementioned distribution valve 68 is a common structure in the prior art, and its structure and principle will not be discussed here.

[0086] In this embodiment, the proportion of water entering the bypass pipe 67 and the third liquid channel 661 is adjusted by the distribution valve 68. Specifically, when the flow rate of water entering the bypass pipe 67 is increased, the flow rate entering the third liquid channel 661 decreases, resulting in less bubble content in the microbubble water. Conversely, when the flow rate entering the third liquid channel 661 is decreased, the flow rate increases, resulting in more bubble content in the microbubble water, thus meeting the user's different requirements for microbubble water generation. Since the diameter of the bypass pipe 67 is larger than the maximum diameter of the throat pipe, adjusting the flow rate of water entering the bypass pipe 67 will change the flow rate of water in the throat pipe, but the overall output flow rate of the microbubble water generator depends on the adjustment of the flow rate of water in the bypass pipe 67.

[0087] Preferably, a 69 is provided at one end of the third pipe 66, which is used to detect flow rate, pressure, and / or temperature. For example, the 69 can be a temperature sensor to detect the temperature of the water flowing into the third liquid channel 661, a pressure sensor to detect the pressure of the water flowing into the third liquid channel 661, or a flow sensor to detect the flow rate of the water flowing into the third liquid channel 661. Devices that simultaneously detect two or more of temperature, pressure, and flow rate can also be used. By detecting flow rate, pressure, and / or temperature, a controller can be used to control the water flow rate, pressure, and temperature to meet different needs.

[0088] The control method for the microbubble generator 600 includes the following steps:

[0089] S1. Obtain the inlet water pressure into the throat.

[0090] For example, 69 is used to detect the pressure of the water entering the third liquid channel 661, which is the inlet water pressure.

[0091] S2. Determine whether the inlet water pressure is greater than the first preset pressure value. If not, proceed to step S3; if yes, proceed to step S4.

[0092] S3. When the inlet water pressure is less than or equal to the first preset pressure value, air is automatically drawn into the throat of the throat tube and mixed with water to form microbubble water.

[0093] When the inlet water pressure is less than or equal to the first preset pressure value, the inlet water pressure will not obstruct the dissolution of air. Therefore, the air can enter the throat and mix with the water simply through the automatic adsorption of the throat, and the resulting microbubble water has sufficient effect.

[0094] S4. When the inlet water pressure is greater than the first preset pressure value, determine whether the inlet water pressure is greater than the second preset pressure value. If not, proceed to step S5; if yes, proceed to step S6.

[0095] In this step, the second preset pressure value is greater than the first preset pressure value.

[0096] S5. When the inlet water pressure is between the first preset pressure value and the second preset pressure value, air is pumped to the throat by the air pump 610.

[0097] When the inlet water pressure is between the first and second preset pressure values, it can affect the dissolution of air. Therefore, the effect of the microbubble water formed solely through the automatic adsorption of the throat tube will be compromised. Thus, by using an air pump 610 to boost air flow to the throat, combined with the automatic adsorption of the throat tube, air can be more easily dissolved in the water, resulting in a better microbubble water effect.

[0098] S6. When the inlet water pressure is greater than the second preset pressure value, adjust the flow rate of water entering the throat pipe through the distribution valve until the inlet water pressure is less than or equal to the second preset pressure value, and then pump air into the throat through the air pump.

[0099] When the inlet water pressure exceeds the second preset pressure value, it severely affects the dissolution of air, and the automatic adsorption of the throat tube cannot effectively allow air to dissolve in the water. Furthermore, even if air is pumped in at this point, the excessive inlet water pressure still prevents proper air dissolution. Therefore, the inlet water pressure needs to be adjusted. Specifically, this can be achieved by diverting some water through the bypass pipe 67 via the distribution valve 68, ensuring that the pressure of the water entering the throat tube is less than or equal to the second preset pressure value. Then, the air is boosted and pumped to the throat by the air pump 610. This, combined with the automatic adsorption of the throat tube, allows air to dissolve in the water more easily.

[0100] It should be noted that in this step, the distribution valve 68 is usually adjusted to make the pressure of the water entering the throat equal to the second preset pressure value. However, due to the different control precision of different distribution valves 68, there may be a situation where the pressure of the water entering the throat is less than the second preset pressure value. Therefore, when it is less than the second preset pressure value, air is also pumped to the throat by the air pump 610 to complete the formation of microbubble water.

[0101] Preferably, in order to better save energy, this embodiment can control the air pump 610 to pump air intermittently when it is started.

[0102] In a second embodiment of this application, the water inlet pipe 300 includes a three-way pipe 301, a filter screen 302, and a plug 303. The three-way pipe 301 has a water inlet port, an installation port, and a water outlet port. The water inlet port and the installation port are arranged laterally back to back. The water inlet port extends to the outside of the housing 100. The filter screen 302 is inserted into the three-way pipe 301 through the installation port and covers the water outlet port. The water outlet port is connected to the water inlet interface. The plug 303 is detachably disposed in the installation port. A first inspection port 1011 is provided on the liner plate 101, and the water inlet port is located in the first inspection port 1011.

[0103] Specifically, the tee pipe 301 is connected to the water inlet of the water valve module 200. The inlet port of the tee pipe 301 is used to connect to the water supply pipe in the user's home. The water entering from the inlet port will be filtered by the filter screen 302, and the filtered water will then be output through the outlet port of the tee pipe 301. The filter screen 302 can effectively filter the water entering the water valve module 200.

[0104] To facilitate future maintenance of the filter, the tee pipe 301 has a removable plug 303 at its installation port. Specifically, the plug 303 is threaded onto the tee pipe 301, allowing the filter 302 to be located inside the tee pipe 301. When cleaning the filter 302 is required, simply remove the plug 303 to pull the filter 302 out of the tee pipe 301 for cleaning.

[0105] The liner 101 is provided with a first inspection port 1011. When the filter screen 302 needs to be repaired and cleaned, the plug 303 can be removed through the first inspection port 1011 to pull out the filter screen 302 in the three-way pipe 301. Thus, the filter screen 302 can be installed and removed without disassembling the liner 101.

[0106] In one embodiment of this application, a rotatable locking component 401 is provided on the water outlet pipe 400; a second inspection port 1012 is provided on the liner plate 101, the second inspection port 1012 is arranged opposite to the locking component 401, and the locking component is connected to the first pipe.

[0107] Specifically, to facilitate maintenance and replacement of the microbubble generator 600, a rotatable locking component 401 is provided on the water outlet pipe 400, which is connected to the first pipe of the microbubble generator 600. For example, the locking component 401 is a nut, and correspondingly, the end of the first pipe is provided with external threads.

[0108] When the microbubble generator 600 needs to be repaired or replaced at the user's home, the locking component 401 can be rotated inside the housing 100 to disassemble and install the microbubble generator 600.

[0109] Correspondingly, a second access port 1012 is provided on the liner 101. The user can insert a wrench into the second access port 1012 to operate the nut on the rear side of the liner 101. The second access port 1012 has a flared structure, the size of which gradually decreases towards the locking component 401. The larger external opening of the second access port 1012 makes it easier for the user to use handles or other tools for disassembly and assembly, thus improving ease of use.

[0110] Based on the above technical solution, optionally, in one embodiment of this application, the water valve module 200 includes a mixing valve 1 and a regeneration valve 4, and the inlet pipe 300, the mixing valve, the water treatment filter element and the outlet pipe 400 are connected in sequence; the inlet pipe 300, the suction pipe, the waste discharge pipe and the water treatment filter element are respectively connected to the regeneration valve.

[0111] Specifically, there are two inlet pipes 300. One inlet pipe 300 is used to introduce cold water, and the other inlet pipe 300 is used to introduce hot water. The two inlet pipes are respectively connected to the mixing valve. The warm water of appropriate temperature output from the mixing valve enters the water treatment filter element for softening treatment, and then is output through the outlet pipe 400.

[0112] After a period of use, the water treatment filter cartridge needs to be regenerated using the salt solution in the salt tank to regenerate the ion exchange resin. During the regeneration process, the inlet pipe for introducing cold water introduces cold water into the regeneration valve. The salt solution in the salt tank is drawn into the regeneration valve and follows the cold water into the water treatment filter cartridge to regenerate the ion exchange resin. The waste liquid output from the water treatment filter cartridge is discharged from the waste discharge pipe through the regeneration valve.

[0113] In some embodiments, such as Figures 4-15 As shown, the 4 provided in this application includes a housing 41 and a regeneration valve core 42.

[0114] For the housing, as follows Figures 7-10 As shown, the housing 41 is provided with a water inlet 401, a liquid outlet 402, a liquid suction port 403, a liquid return port 405, a waste discharge port 406, and a water replenishment port 407. The housing 41 is provided with a functional flow channel 404, which has a converging section 4041, an expanding section 4042, and a diversion section 4043. The converging section 4041 and the expanding section 4042 are connected to form a negative pressure zone. The diversion section 4043 is connected to the negative pressure zone. The converging section 4041 is selectively connected to the water inlet 401. The expanding section 4042 is selectively connected to the liquid outlet 402. The diversion section 4043 is connected to the liquid suction port 403.

[0115] Specifically, during the regeneration process, the converging section 4041 is connected to the inlet port 401, and the expanding section 4042 is connected to the outlet port 402. Cold water is introduced into the functional flow channel 404 via the inlet port 401. The water flow is guided from the converging section 4041 to the expanding section 4042. Under the action of the converging section 4041, the flow velocity gradually increases, and the water enters the expanding section 4042 to create a negative pressure. Under this negative pressure, the guiding section 4043 draws in the salt solution from the salt tank 5 through the suction pipe. The salt solution is drawn into the expanding section 4042, mixed with the cold water, and then output from the outlet port 402 and enters the water treatment filter element through the inlet hole 242, thereby regenerating the regenerating resin within the water treatment filter element.

[0116] Cold water flows in the functional flow channel 404, and the negative pressure zone formed at the junction of the converging section 4041 and the expanding section 4042 generates negative pressure on the guiding section 4043, which is used to draw in the salt solution from the salt tank 5. In this way, there is no need to configure an additional power source to drive the flow of the salt solution in the salt tank 5, achieving a compact structural design and reducing manufacturing costs.

[0117] Preferably, the converging section 4041 is curved toward the expanding section 4042 to generate a certain swirling flow in the water, thereby increasing the water flow velocity entering the expanding section 4042. Furthermore, the liquid outlet direction of the converging section 4041 is toward the outlet of the expanding section 4042, which can more effectively create a stronger negative pressure at the junction of the converging section 4041 and the expanding section 4042, thereby increasing the suction force generated by the diversion section 4043.

[0118] To facilitate the discharge of waste liquid generated during the regeneration process, the regeneration valve 4 is also equipped with a return port 405 and a waste discharge port 406. The return port 405 is selectively connected to the waste discharge port 406. The return port 405 is also connected to the water outlet 243.

[0119] Specifically, during the regeneration process, the converging section 4041 is connected to the inlet port 401, the expanding section 4042 is connected to the outlet port 402, and the return port 405 is connected to the waste discharge port 406. Thus, cold water enters the functional flow channel 404 and is drawn into the salt solution in the salt tank 5, then flows out from the outlet port 402 into the water treatment filter element. This regenerates the regenerating resin in the water treatment filter element 240, turning it into waste liquid. The waste liquid flows out from the outlet hole 243 and into the large return port 405, and finally flows out from the regeneration valve 4 through the waste discharge port 406. For convenient drainage, a wastewater pipe (not shown) is also installed on the waste discharge port 406.

[0120] In another embodiment, to facilitate the user in adding water to the brine tank 5, the regeneration valve 4 is also equipped with a water inlet 407, which is selectively connected to the water inlet 401; the water inlet 407 is used to add water to the brine tank 5.

[0121] Specifically, after the user replenishes the salt tank 5 with regenerated salt, water also needs to be added to the salt tank 5. At this time, the water inlet 407 in the regeneration valve 4 is connected to the water inlet 401, and cold water is introduced through the water inlet 401 and delivered to the salt tank 5 from the water inlet 407.

[0122] In some embodiments, an internal partition 411 is formed in the housing 41 of the regeneration valve 4, which divides the interior of the housing 41 into two mounting cavities. The partition 411 is grooved to form a functional flow channel 404. According to the flow path design requirements, the partition 411 is provided with multiple connection holes 410 to meet the requirements of the functional flow channel 404 being connected to the water flow path of the inlet port 401, the outlet port 402 and the suction port 403 respectively.

[0123] In addition, a plug 412 is provided on the housing 41. The plug 412 can be installed on the housing 41 and seal and cover the functional flow channel 404 on the partition 411 to form a closed water flow channel, thereby reducing the processing difficulty of the functional flow channel 404 in the housing 41.

[0124] During assembly, one of the mounting cavities is used to mount the regeneration valve core 42, and the other mounting cavity has a head 412.

[0125] The functional flow channel configured in the regeneration valve 4 can use the Venturi principle to draw in the brine in the brine tank through the water inlet 401 and send it into the water treatment filter element. This allows the regeneration valve 4 to draw in the brine in the brine tank while switching water paths, thus eliminating the need for additional power components for the brine tank and reducing manufacturing costs.

[0126] For the regeneration valve core, as Figures 11-15 As shown, the regeneration valve core 42 includes a fixed valve plate 421 and a rotating valve plate 422. The fixed valve plate 421 is provided with at least one inlet / outlet group, which includes two inlet / outlet ports 4211. The rotating valve plate 422 is provided with a communicating groove 4221 that cooperates with the inlet / outlet group, and the edge of the rotating valve plate 422 is also provided with an inlet notch 4222 for water intake.

[0127] The rotating valve plate 422 is attached to the fixed valve plate 421 and can rotate relative to the fixed valve plate 421. The connecting groove selectively connects the two inlet and outlet ports 4211 in the corresponding inlet and outlet group, and the inlet notch 4222 selectively connects to the inlet and outlet ports 4211.

[0128] Specifically, in actual use, a corresponding number of inlet / outlet groups are configured according to the flow path on / off requirements of the regeneration valve core. The on / off control of two inlet / outlet ports 4211 within the same inlet / outlet group is controlled by rotating valve plate 422. Furthermore, the inlet port is connected to the inlet notch, and the outlet port, suction port, and return port are connected to their respective inlet / outlet ports, thereby connecting the regeneration valve core to the interface configured on the housing to satisfy water path control.

[0129] In addition, the incoming water flows into the interior of the regeneration valve core through the inlet notch 4222. The connecting groove selectively connects the two inlet and outlet ports 4211 in the corresponding inlet and outlet group, so that the water entering from the inlet notch 4222 flows through the two connected inlet and outlet ports 4211 and is finally output.

[0130] The following explanation, in conjunction with the accompanying drawings, describes the different states of the regeneration valve core. For example... Figures 3-5 As shown, the solid line represents the fixed valve plate 421, while the dashed line represents the rotating valve plate 422.

[0131] like Figure 13 As shown, when the regeneration valve core is in the closed state, the water inlet 4222 is blocked by the fixed valve plate 421, and the water flow cannot enter the inlet / outlet 4211 provided on the fixed valve plate 421.

[0132] like Figure 14 As shown, when the regeneration valve core is in the regeneration state, after rotating the valve plate 422 by a set angle, the inlet notch 4222 and the valve core are aligned. Figure 13 The corresponding inlet / outlet 4211 on the left side is connected, and simultaneously, the corresponding inlet / outlet 4211 is connected through the second connecting channel, so that the water input from the inlet gap 4222 is finally output through the inlet / outlet 4211 connected to the water treatment filter element. Meanwhile, refer to... Figure 4 The two inlet and outlet ports 4211 on the right side are used to connect the water outlet of the water treatment filter element and the waste outlet through the corresponding connecting groove.

[0133] like Figure 15 As shown, when the regeneration valve core is in the state of replenishing water to the brine tank, after rotating the valve plate 422 by a set angle, the water inlet 4222 and the valve plate 4222 are aligned. Figure 5 The inlet and outlet 4211 of the middle and lower part are connected. Water input from the inlet gap 4222 is output through the inlet and outlet 4211 to the water replenishment port 407 and flows into the salt tank.

[0134] In some embodiments, the regeneration valve core further includes a valve body 423, a fixed valve plate 421 is fixedly disposed in the valve body 423, a rotating valve plate 422 is rotatably disposed in the valve body 423, and a perforated hole 4231 for water inlet is provided on the circumferential wall of the valve body 423.

[0135] Specifically, to facilitate the installation of the regeneration valve core in the regeneration valve housing, the fixed valve plate 421 and the rotating valve plate 422 are installed in the valve body 423. In this way, the valve body 423 can be used to install it in the housing.

[0136] The valve body 423 is a sleeve structure. One end of the valve body 423 is provided with an installation port (unmarked), and the other end is provided with an installation hole (unmarked). The rotating valve plate 422 and the fixed valve plate 421 are installed in the valve body 423 in sequence through the installation hole, so as to realize the modular design by using the valve body.

[0137] In some embodiments, for the convenience of water circuit connection and user operation, the regeneration valve core further includes a water distribution plate 424 and a valve stem 425. The water distribution plate 424 is provided with a plurality of through holes 4241 and is disposed in the mounting port. The valve stem 425 passes through the mounting hole and is connected to the rotating valve plate 422. The fixed valve plate 421 is disposed on the water distribution plate 424 and is located between the water distribution plate 424 and the rotating valve plate 422. The inlet and outlet ports 4211 are connected to the corresponding through holes 4241.

[0138] Specifically, during assembly, the valve stem 425, the rotating valve plate 422, the fixed valve plate 421, and the water distribution plate 424 are sequentially inserted into the valve body 423 through the mounting port, and the valve stem 425 extends from the mounting hole to the outside of the valve body 423.

[0139] The fixed valve plate 421 and the rotating valve plate 422 are made of wear-resistant materials (such as ceramic valve plates). By configuring a water distribution plate 424 on the outside of the fixed valve plate 421, on the one hand, the water distribution plate 424 can be used to connect the inlet and outlet ports 4211 on the fixed valve plate 421 to the water flow channel on the housing through the corresponding through holes 4241. On the other hand, the water distribution plate 424 squeezes the fixed valve plate 421 from the outside, so that the fixed valve plate 421 and the rotating valve plate 422 are tightly attached together to ensure a sealed connection between the two.

[0140] One end of the valve stem 425 is sealed and inserted into the valve body 423 and connected to the rotating valve plate 422, while the other end is exposed and equipped with a knob to facilitate the user to drive the rotating valve plate 422 to rotate via the knob.

[0141] In order to achieve a tight seal between the fixed valve plate 421 and the water distribution plate 424, an inner sealing gasket 426 is provided on the inner side of the water distribution plate 424. The inner sealing gasket is used to seal the outer periphery of the through hole 4241 and the corresponding inlet / outlet 4211. An outer sealing gasket 427 is provided on the outer side of the water distribution plate 424. The outer sealing gasket is used to seal the connection between the through hole 4241 and the outer shell.

[0142] Specifically, the inner sealing gasket is used to seal the connection between the through hole 4241 and the inlet / outlet 4211. Similarly, the outer sealing gasket is provided on the outside of the water distribution plate 424, which is used to seal the connection between the through hole 4241 and the outer shell.

[0143] In some embodiments, to facilitate the installation of the sealing gasket, mounting grooves can be provided around the through hole 4241 on the inner and outer surfaces of the water distribution plate 424, and the outer sealing gasket and the inner sealing gasket are located in the mounting grooves. Specifically, the structure of the mounting groove matches the shape of the sealing gasket, and the sealing gasket is snapped into the mounting groove during assembly for easy assembly.

[0144] In some embodiments, the edge of the mounting port is provided with a first notch 4232, and a first locking block 4241 is provided on the water distribution plate 424, the first locking block being locked in the first notch. A second locking block 4242 is provided on the water distribution plate 424, and a second notch 4212 is provided on the fixing valve plate 421, the second locking block being locked in the second notch.

[0145] Specifically, during the assembly process, the valve stem 425, the rotating valve plate 422, the fixed valve plate 421, and the water distribution plate 424 are sequentially installed into the valve body 423 through the installation port. The water distribution plate 424 is positioned and does not rotate by the first locking block cooperating with the first notch. Similarly, the second locking block cooperates with the second notch to position and fix the valve plate 421 so that it does not rotate.

[0146] In one embodiment, for ease of connection and assembly, the water distribution plate 424 is connected to the valve body 423 by a snap-fit ​​method. Specifically, the edge of the mounting port is provided with a buckle (unmarked), and the water distribution plate 424 is provided with a claw (unmarked), which is engaged in the buckle.

[0147] In another embodiment, the valve body 423 includes a first sleeve segment (unmarked) and a second sleeve segment (unmarked) connected together. The diameter of the first sleeve segment is smaller than the diameter of the second sleeve segment. The port of the first sleeve segment forms the mounting hole, and the port of the second sleeve segment forms the mounting opening. The second sleeve segment is provided with the hollow hole. A first sealing ring (unmarked) is fitted on the valve stem 425. The first sealing ring is sandwiched between the inner wall of the first sleeve segment and the valve stem 425. A second sealing ring 4213 is fitted on the second sleeve segment. The second sealing ring is located between the hollow hole and the first sleeve segment.

[0148] Specifically, the first sealing ring enables the valve stem 425, which extends out of the valve body 423, to maintain a water-sealed connection with the valve body 423.

[0149] More importantly, since the second pipe sleeve is provided with the hollow hole to meet the water inlet requirements of the water inlet gap 4222, the second sealing ring is provided on the second pipe sleeve so that after the valve body 423 is installed in the third installation space, water is ensured to flow into the water inlet gap 4222 through the hollow hole inside the second sealing ring.

[0150] In this way, water can be supplied from one side of the valve body 423 through the water inlet notch 4222, allowing the rotating valve plate 422 to meet different water supply requirements in two different positions, thereby simplifying the overall structure of the valve plate and improving its reliability.

[0151] In other embodiments, a mixing valve 1 is provided with a mixing valve core 11, which has a first inlet 12, a second inlet 13, and a mixed water outlet 14. Cold water introduced by one inlet pipe 300 enters the first inlet 12, and hot water introduced by the other inlet pipe 300 enters the second inlet 13. The cold water and hot water are mixed in the mixing valve core and then output through the mixed water outlet 14.

[0152] Specifically, for a water softener with microbubble function, the mixing valve is used to mix hot and cold water to obtain water at a suitable temperature, and the water output from the mixing water outlet 1 by the mixing valve will enter the water treatment filter for water softening treatment.

[0153] The water output from the mixed water outlet 1 enters the water treatment filter element 3 through the inlet 301. The water entering the water treatment filter element 3 will undergo ion exchange with the regenerated resin inside the water treatment filter element 3 to obtain soft water. The soft water is output from the outlet 302 of the water treatment filter element 3 and finally delivered to the water terminal through the outlet connector 300.

[0154] As the water treatment filter cartridge 3 is used for an extended period, the processing capacity of its internal regenerated resin will decrease, necessitating regeneration. In this case, the regeneration valve 4 is used to control the water flow for regeneration.

[0155] During the regeneration process, the converging section 4041 is connected to the inlet port 401, and the expanding section 4042 is connected to the outlet port 402. Cold water introduced through the inlet pipe 300 is introduced into the functional flow channel 404 via the inlet port 401. The water flow is guided from the converging section 4041 to the expanding section 4042. Under the action of the converging section 4041, the flow velocity gradually increases, and the water enters the expanding section 4042 to create a negative pressure. Under this negative pressure, the guiding section 4043 draws in the salt solution from the salt tank 5 through the suction pipe. The salt solution, after being drawn into the expanding section 4042 and mixed with the cold water, is output from the outlet port 402 and enters the water treatment filter element through the inlet hole 301, thereby regenerating the regenerative resin within the water treatment filter element.

[0156] In addition, as needed, a water softener with microbubble function can be configured with multiple water treatment filter cartridges to enhance the water softening capacity. There is no limit to the number of water treatment filter cartridges 3.

[0157] Since water softeners with microbubble functionality are typically installed in shower rooms where space is limited, the regeneration valve 4 draws salt solution from the brine tank 5 using cold water introduced through the inlet pipe. This cold water flows through the functional flow channel 404, utilizing the negative pressure zone formed at the junction of the converging section 4041 and the expanding section 4042 to create negative pressure on the drainage section 4043, which then draws the salt solution from the brine tank 5. This eliminates the need for an additional power source to drive the flow of the salt solution in the brine tank 5, resulting in a compact design and reduced manufacturing costs.

[0158] By configuring a functional flow channel in the regeneration valve, the water introduced through the inlet pipe can be used to draw brine from the brine tank and send it into the water treatment filter element. This allows the regeneration valve to not only switch water paths but also draw brine from the brine tank, eliminating the need for additional power components for the brine tank and reducing manufacturing costs.

[0159] In other embodiments, in order to regulate the water flow and control the opening and closing of the water path, the water softener with microbubble function also includes a regulating valve 2, which is provided with a cold water flow channel 201, a hot water flow channel 202 and an outlet water flow channel 203.

[0160] The cold water channel 201 is connected to the second inlet 13, the hot water channel 202 is connected to the first inlet 12, and the soft water filter 3 is connected between the mixed water outlet 14 and the outlet channel 203.

[0161] In addition, regulating valve 2 is used to selectively open and close the cold water flow channel 201 and the hot water flow channel 202; and / or, regulating valve 2 is used to selectively open and close the outlet water flow channel 203.

[0162] Specifically, in actual use, the cold water channel 201 of the water softener with microbubble function is used to receive cold water from the tap water pipe in the user's home, while the hot water channel 202 is used to deliver hot water from the water heater in the user's home.

[0163] The cold water conveyed by the cold water channel 201 and the hot water conveyed by the hot water channel 202 flow into the mixing valve 1 and enter the mixing valve core 11. The mixing valve core 11 can mix the cold and hot water so that the water temperature output from the mixing valve core 11 is maintained within the water temperature fluctuation range set by the user.

[0164] After the mixing valve core 11 mixes the hot and cold water, the water flows out through the mixed water outlet 14 and into the soft water filter 3.

[0165] After being processed by the water softener 3, the water flows back into the regulating valve 2, and finally flows out through the outlet channel 203 in the regulating valve 2 to be output from the water terminal (faucet or shower head, etc.) in the user's home.

[0166] Specifically, the cold water channel 201, hot water channel 202, and outlet water channel 203 of the regulating valve 2 can be switched on and off as needed. It can be categorized into at least three structural forms:

[0167] In method one, regulating valve 2 can control the opening and closing of cold water channel 201, hot water channel 202, and outlet water channel 203 respectively.

[0168] In actual use, when the user uses water, the regulating valve 2 simultaneously adjusts the cold water channel 201, hot water channel 202, and outlet channel 203 to be in a continuous state. The cold and hot water enter through the cold water channel 201 and hot water channel 202 and are processed by the soft water filter 3 before being output from the outlet channel 203. When the user does not use water, the cold water channel 201, hot water channel 202, and outlet channel 203 are simultaneously cut off.

[0169] In the second method, the regulating valve 2 can control the opening and closing of the cold water channel 201 and the hot water channel 202 respectively, while the outlet channel 203 is always in a conductive state.

[0170] In actual use, when the user uses water, the regulating valve 2 simultaneously adjusts the cold water channel 201 and the hot water channel 202 to be in a passable state. The cold and hot water enter through the cold water channel 201 and the hot water channel 202 and are processed by the soft water filter 3 before being output from the outlet channel 203. When the user does not use water, the cold water channel 201 and the hot water channel 202 are simultaneously cut off.

[0171] Method 3: The regulating valve 2 can open and close the water flow channel 203, while controlling the cold water flow channel 201 and the hot water flow channel 202 to always be in a conductive state.

[0172] In actual use, when the user uses water, the outlet channel 203 is adjusted to be open through the regulating valve 2. Hot and cold water enter through the cold water channel 201 and the hot water channel 202 and are processed by the soft water filter 3 before being output from the outlet channel 203. When the user does not use water, the outlet channel 203 is cut off.

[0173] By setting up cold water, hot water, and outlet water channels in the regulating valve, the water softener is connected between the outlet water channel and the mixing water outlet of the mixing valve. During use, the flow of water from the water softener is controlled by adjusting the flow channels through the regulating valve. This allows the hot water output from the water heater to be processed by the mixing valve core and then purified or mineralized by the water softener before finally flowing out from the outlet water channel in the regulating valve. Since the water softener is connected between the regulating valve and the mixing valve, there is no need to add an additional independent valve for control, thereby reducing the number of valves used, lowering the manufacturing cost of water softeners with microbubble function, and reducing the overall size.
