Due to their end-use applications, they enjoy the highest customer interaction rate among purified water products. Consequently, as people increasingly pursue a superior drinking experience and healthier drinking water, demand for more advanced features in these dispensers is growing. These include features such as mineralization of water, the addition of trace elements to the human body, and easy filter replacement.

For example, traditional instant hot pipeline water dispensers have a single function and cannot provide mineral trace elements. If a mineralized filter element is added, an additional valve is required to switch the water path, resulting in a complex structure, inconvenient filter element replacement, and the system cannot automatically restore the basic water path after the filter element is removed. In addition, the installation of mineralized filter elements often destroys the integrity of the product and lacks an accurate life monitoring mechanism.

[0034] like Figures 1 to 6 The instant hot mineralized water dispenser shown includes a water dispenser body and a water receiving box 1 mounted on the dispenser body. The dispenser body includes a housing 2, within which a water inlet solenoid valve 3, a water tank 4, a water supply pump 5, a heating module 6, and a water outlet 7 are sequentially connected. The dispenser is characterized in that a mineralized filter element assembly is connected between the water tank 4 and the water supply pump 5 within the housing 2. The mineralized filter element assembly includes a water path switching module 8 and a mineralized filter element 9 detachably mounted on the water path switching module 8. The mineralized filter element 9 includes a housing and a filter element assembly mounted within the housing. The housing has a water inlet end 10 and a water outlet end 11. The water path switching module 8 includes a filter element seat 12 connected to the water tank 4 and the water supply pump 5. The filter element seat 12 is formed with a mounting cavity 13, and the mineralized filter element 9 is mounted in the mounting cavity 13. The filter element seat 12 is constructed with a water inlet 14 and a water outlet 15. A straight waterway 16 and a filtered waterway 17 connecting the water inlet 14 and the water outlet 15 are formed in the filter element seat 12. The filtered waterway 17 passes through the mineralized filter element 9. A switching valve 18 is provided on the straight waterway 16 in the filter element seat 12, and a water inlet check valve 19 and a water outlet check valve 20 are provided on the filtered waterway 17. When the mineralized filter element 9 is installed in the installation cavity 13, the shell of the mineralized filter element 9 can act on the water inlet check valve 19, the water outlet check valve 20 and the switching valve 18 to guide the water through the filtered water path 17. The water inlet check valve 19 and the water outlet check valve 20 are opened, and the switching valve 18 is closed. The water flows through the mineralized filter element 9 and then to the water supply pump 5. When the mineralized filter element 9 is removed, the water inlet check valve 19 and the water outlet check valve 20 are reset and closed, the switching valve 18 is reset and opened to connect the direct waterway 16 , and the water flows directly to the water supply pump 5 .

[0035] In the above technical solution, a mineralized filter element assembly is installed on a traditional instant hot water dispenser. The mineralized filter element assembly includes a detachable mineralized filter element and a water channel switching module. The water channel switching module is connected to the basic water channel of the water dispenser to connect the water tank and the water supply pump. After the mineralized filter element is assembled on the filter element seat of the water channel switching module, the water channel is automatically guided through the filter by the cooperation of three valves. This mineralizes drinking water, increases the body's intake of trace elements, and addresses the single-function shortcomings of instant hot water dispensers, offering users a more versatile experience. When removed, the filter seamlessly switches to a direct water path, eliminating the need for additional valves to switch water paths and maintaining basic drinking water functionality. Disassembly and assembly are also convenient, enabling plug-and-play operation of the mineralized filter element.

[0036] Furthermore, the filter element seat 12 includes a connecting portion and a first conversion tube 21, a second conversion tube 22, and a third conversion tube 23 formed on the side of the connecting portion. The first conversion tube 21, the second conversion tube 22, and the third conversion tube 23 are connected and their outer ends are closed by a baffle 24. A first channel 25, a second channel 26, and a third channel 27 communicating with the installation cavity 13 are formed in the first conversion tube 21, the second conversion tube 22, and the third conversion tube 23, respectively. A first baffle wall 28 is constructed between the first channel 25 and the second channel 26, and a second baffle wall 29 is constructed between the second channel 26 and the third channel 27. A water inlet pipe 30 having a water inlet 14 is formed on the first conversion pipe 21. The first channel 25, the second channel 26, and the first baffle 28 are spaced apart from the baffle 24 to form the straight waterway 16. The second channel 26, the third channel 27, and the inner cavity of the mineralized filter element 9 form the filtered waterway 17. A water outlet pipe 31 having a water outlet 15 is formed on the second conversion pipe 22 and the third conversion pipe 23. The lower end of the water outlet pipe 31 extends into the filter element seat 12 and is sealed between the baffle 24. The lower end of the water outlet pipe 31 is provided with a first water outlet 32 facing the straight waterway 16 and a second water outlet 33 facing the third channel 27. The water inlet check valve 19, the switching valve 18 and the water outlet check valve 20 are respectively adapted to be installed in the first channel 25, the second channel 26 and the third channel 27; when the mineralized filter element 9 is installed on the installation cavity 13, the switching valve 18 closes the first water outlet 32, and the water inlet check valve 19 and the water outlet check valve 20 are opened to open the first channel 25 and the second channel 26 to connect the water inlet 14 and the second water outlet 33; when the mineralized filter element 9 is removed, the switching valve 18 opens the first water outlet 32, and the water inlet check valve 19 and the water outlet check valve 20 close the first channel 25 and the second channel 26.

[0037] In the above technical solution, specifically, three channels are formed in the three conversion tubes, three valve bodies are installed in the three channels respectively, and a first baffle wall and a second baffle wall are set between the three channels to isolate the straight / filtered water channels to avoid water cross-contamination, and a first water outlet and a second water outlet are respectively set at the bottom of the water outlet, corresponding to the straight water channel and the filtered water channel respectively, so as to achieve the purpose of accurately controlling the water flow.

[0038] Furthermore, the water inlet check valve 19 and the water outlet check valve 20 both include a first valve housing 34 embedded in the channel, a first valve core 35 provided on the first valve housing 34, and a first spring 36 sleeved on the first valve core 35, and a guide channel 37 is formed in the first valve housing 34; the switching valve 18 includes a second valve housing 38 embedded in the channel, a second valve core 39 provided on the second valve housing 38, and a second spring 40 sleeved on the second valve core 39; the side of the shell is spaced apart with a first butt joint 41, a second butt joint 42 and a third butt joint 43 adapted to extend into the first channel 25, the second channel 26 and the third channel 27, the outer ends of the first butt joint 41 and the third butt joint 43 are open, and the outer end of the second butt joint 42 is closed; the first butt joint 41 and the third butt joint 43 can act on the first valve core 35 to open the guide channel 37, and the second butt joint 42 can act on the second valve core 39 to close the first water outlet 32.

[0039] In the above technical solution, when the mineralized filter element is installed into the filter element seat through the docking tube guide, the docking tube at the front end of the filter element pushes each valve core to open, wherein the water inlet check valve and the water outlet check valve are opened, and the switching valve is closed, so that the channel is switched to the water inlet end of the mineralized filter element (filter water path), and after passing through the mineralized filter element, the water flows out from the water outlet end of the mineralized filter element into the third channel to the second outlet to the water supply pump; when the mineralized filter element is removed, each valve core slides downward due to the spring force, wherein the water inlet check valve and the water outlet check valve are closed, and the switching valve is opened, so that the channel switching is realized without passing through the filter element device.

[0040] Furthermore, the upper side of the first retaining wall 28, which faces the first water outlet 32, deviates toward the second channel 26 to form an inclined wall 44. Under the action of an external force, the plug of the second valve core 39 can abut and seal between the inclined wall 44 and the upper edge of the first water outlet 32. In this technical solution, the inclined wall design ensures that the plug of the switching valve is sealed between the inclined wall and the upper edge of the first water outlet, preventing the plug of the switching valve from being pushed out and thus preventing it from being sealed.

[0041] Furthermore, a tight-fitting ring 45 is circumferentially provided on the first butt joint pipe 41 , the second butt joint pipe 42 and the third butt joint pipe 43 .

[0042] In this technical solution, the tight-fitting ring increases the friction resistance to prevent the filter element from vibrating and falling off.

[0043] Furthermore, the connecting portion is a square frame 46 with an opening formed on the frame 46. A plug-in strip 47 is formed circumferentially around the edge of the opening. The housing includes a square main body 48 adapted to fit within the mounting cavity 13, and a plug-in section 49 disposed on the rear side of the main body 48. A slot is circumferentially formed on the plug-in section 49 to mate with the plug-in strip 47. The filter element assembly is disposed within the main body 48. In this technical solution, the frame and main body fit together between the mineralized filter element and the filter element seat, and the plug-in strip / slot guides mate, forming a modular quick-release structure that is very convenient for assembly and disassembly.

[0044] Furthermore, a layered plate 50 is longitudinally disposed on the inner wall of the main body 48 between the first and second butting tubes 41, 42. The outer end of the layered plate 50 is spaced from the inner wall of the main body 48. A transverse plate 51 extends from the outer end of the layered plate 50 toward the first channel 25. The outer end of the transverse plate 51 is spaced from the inner wall of the main body 48. In this technical solution, to fully utilize the mineralized filter element, the mineralized filter element involved in this system adopts a layered stepped design, namely, layered plates and transverse plates. This design extends the water flow path without affecting the water flow rate, ensuring that the filter media is fully immersed in water, thereby maintaining the concentration of trace elements throughout its life cycle. The filter element assembly mainly consists of a filter element body, a filter element cover, a filter baffle, mineralized filter media, and a filter screen.

[0045] Furthermore, a mounting hole 52 corresponding to the frame 46 is formed on the back side of the water dispenser housing 2, on the back side of the water receiving box 1. The mineralized filter element 9 is installed into the water dispenser housing 2 along the mounting hole 52. Connecting ears 53 are provided on both sides of the frame 46, and the connecting ears 53 are connected to the water dispenser housing 2 via bolts 54. In this technical solution, the back side of the mounting hole serves as the frame; the mineralized filter element is installed on the back side of the water receiving box. The hidden mineralized filter element mounting structure design allows the mineralized filter element to be replaced by simply removing the water receiving box and inserting the mineralized filter element through the mounting hole, which facilitates the removal and installation of the mineralized filter element without affecting the product's aesthetics and integrity.

[0046] Furthermore, a filter presence sensor 55 is provided at the upper end of the filter cartridge seat 12 to sense whether the mineralized filter cartridge 9 is installed. After the mineralized filter cartridge 9 is installed for the first time, the filter presence sensor 55 transmits the sensing information to the system, and the system starts the filter cartridge life calculation. When the filter cartridge is removed, the filter presence sensor 55 transmits the sensing information to the system, and the system issues a reminder. A flow sensor 56 and an over-flow sterilization device 57 are provided in sequence between the water outlet of the water tank 4 and the water inlet 14 of the filter cartridge seat 12. In this technical solution, in order to ensure the applicability of its mineralized filter cartridge, the system is equipped with a filter presence sensor. After the filter cartridge is installed for the first time, the system starts the filter cartridge life calculation when its sensing switch is triggered. When the filter cartridge is removed, the system issues a reminder. In order to make the filter cartridge life calculation more accurate, the system is also equipped with a flow detection device, which can calculate the life of the mineralized filter cartridge through dual logic of time and flow. In addition, the flow detection device provided can provide more accurate data to its heating system, making the temperature and water outlet flow rate presented by its heating system more stable. At the same time, the innovative design of the combined application of the over-flow sterilization device and the mineralized filter element can not only meet the hygiene and safety of drinking water, but also meet the human body's trace element intake and improve the taste of drinking water.

[0047] In this specific embodiment, the existing instant hot pipeline water dispenser has a single function. If a mineralized filter element is added, an additional valve switching water path is required, resulting in a complex structure, inconvenient filter element replacement, and the system cannot automatically restore the basic water path after the filter element is removed. The above solution constructs a purely mechanical adaptive water path, that is, a water path switching module is connected to the basic water path of the water dispenser to conduct the water tank and the water supply pump. After the mineralized filter element is assembled on the filter element seat of the water path switching module, the three valves are coordinated to automatically guide the filtered water path, realizing the drinking water mineralization function, increasing the human body's trace element intake, and solving the shortcomings of the single function of the instant hot pipeline water dispenser, thereby satisfying the user's more functional experience. When removed, it seamlessly switches to the straight water path. The user does not need to configure additional valves to switch the water path to maintain the basic drinking water function. It is also very convenient to disassemble and assemble, and the mineralized filter element can be plug-and-play.

[0048] At the same time, it realizes the trinity of "mineralization-sterilization-flow control", precise reminders for the use of mineralized filter elements, and the beautiful design of hidden installation of mineralized filter elements.
