Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0047] To address the issue that existing water purifiers have their water tanks fixed inside the machine, users need to fill a cup with purified water before pouring it into the larger cooking vessel when they need to use the purified water for cooking rice or making soup, which is inconvenient and affects the user experience.

[0048] like Figures 1 to 3 As shown, this embodiment discloses a water purification device, which includes a body 1, a water production module, a purified water tank 3, a hydrogen production module, a power supply module, a water inlet 2, a water inlet pipe, and a water pump 8. The purified water tank 3 is detachably installed on the body 1. The purified water tank 3 includes a tank body 31 and a tank cover 32. The tank body 31 is provided with a water inlet and a water outlet. The tank cover 32 is fastened to the tank body 31 to close the water outlet. A water inlet valve assembly 4 is fixed inside the water inlet. The hydrogen production module is installed on the tank body 31 and is used to treat the water in the tank body 31 to enrich it with hydrogen, forming hydrogen-rich water and improving the water quality. The power supply module includes a male power supply terminal 71 and a female power supply terminal 72. The female power supply terminal 72 is installed on the hydrogen production module and electrically connected to it. When the water tank 3 is installed on the body 1, the male power supply terminal 71 and the female power supply terminal 72 are connected to supply power to the hydrogen production module, enabling the hydrogen production module to treat the water in the tank 31. When the water tank 3 is removed from the body 1, the male power supply terminal 71 and the female power supply terminal 72 are disconnected, and the hydrogen production module stops receiving power.

[0049] like Figures 2 to 5 As shown, a water outlet valve assembly 5 is installed on the main body 1. The water production module is installed inside the main body 1. The inlet of the water production module is connected to the tap water pipe, and the outlet of the water production module is connected to the water outlet valve assembly 5 through a purified water pipe 9. A purified water valve is installed on the purified water pipe 9 to control the opening and closing of the purified water pipe 9. The water production module includes a pre-filter, a booster pump, and a reverse osmosis filter arranged in series. The pre-filter is connected to the tap water pipe through a pipeline. The purified water outlet of the reverse osmosis filter is connected to the purified water pipe 9, and the concentrated water outlet of the reverse osmosis filter is connected to a concentrated water pipe. Tap water becomes purified water after being filtered by the pre-filter and the reverse osmosis filter, and is supplied through the purified water pipe 9 by the booster pump.

[0050] like Figure 2 and Figure 5As shown, the water inlet 2 is installed on the body 1, the inlet end of the water inlet pipe is connected to the clean water pipe 9 and is located between the outlet valve assembly 5 and the clean water valve, the outlet end of the water inlet pipe is connected to the water inlet 2, the water pump 8 is installed on the water inlet pipe, and the water inlet pipe is also equipped with a water inlet valve to control the opening and closing of the water inlet pipe.

[0051] When the purified water tank 3 is installed on the main body 1, the inlet valve assembly 4 and the outlet valve assembly 5 abut against each other, thus opening the water passage between them. Opening the purified water valve activates the water production module. Raw water supplied from the tap water pipe is purified by the module, forming purified water, which is then supplied to the purified water tank 3 for storage via the purified water pipe 9, the outlet valve assembly 5, and the inlet valve assembly 4. Simultaneously, the power supply module supplies power to the hydrogen production module, which then enriches the water in the purified water tank 3 with hydrogen.

[0052] When users collect drinking water, the water purification valve is closed, the water inlet valve is opened, and the water pump 8 is activated. The hydrogen-rich water from the tank is supplied through the inlet valve assembly 4, the outlet valve assembly 5, and the water inlet pipe, exiting from the water inlet 2. When users need to use the hydrogen-rich water for cooking or making soup, the tank 31 can be detached from the main body 1. At this time, the inlet valve assembly 4 and the outlet valve assembly 5 are not in contact. The inlet valve assembly 4 can close the inlet, and the outlet valve assembly 5 can close the outlet of the water purification pipe 9, reducing the possibility of leakage of water from the tank 31 or the water purification pipe 9. Opening the lid 32 allows water from the tank 31 to be poured directly into the cookware, which is more convenient than filling a cup with water from the water inlet 2 and then pouring it into the cookware, thus improving the user experience.

[0053] like Figure 4 and Figure 5 As shown, specifically, the water inlet valve assembly 4 includes a water inlet connector 41, a check valve core 42, a first elastic element 43, a first sealing element, and a cap 46. The water inlet connector 41 is fixed to the inner wall of the water inlet. The first sealing element includes an integrally formed connecting part 441 and a sealing part 442. The first sealing element is made of silicone material. The connecting part 441 abuts against the end of the water inlet connector 41, and the sealing part 442 fits against the inner wall of the water inlet connector 41. The cap 46 abuts against the connecting part 441 and fits onto the water inlet connector 41 to fix the first sealing element. The check valve core 42 is slidably disposed inside the water inlet connector 41, and a water inlet channel 45 is left between the check valve core 42 and the inner wall of the water inlet connector 41 for water to flow through. The first elastic element 43 is a first spring, one end of which is fixed to the inner wall of the water outlet end of the water inlet connector 41, and the other end is fixed to the check valve.

[0054] When the inlet valve assembly 4 and the outlet valve assembly 5 come into contact, the outlet valve assembly 5 pushes the check valve core 42, causing the check valve core 42 to retract back into the inlet connector 41 and compress the first spring. The purified water flows into the tank 31 through the outlet valve assembly 5, the inlet channel 45, and the outlet of the inlet connector 41, or flows out of the inlet 2 from the tank 31 through the outlet of the inlet connector 41, the inlet channel 45, the outlet valve assembly 5, and the inlet pipe. When the inlet valve assembly 4 and the outlet valve assembly 5 are not in contact, the first elastic element 43 drives the check valve core 42 to move towards the outlet valve assembly 5, so that one end of the check valve core 42 extends out of the inlet end of the inlet connector 41, and the other end abuts against the sealing part 442, sealing the inlet of the inlet valve assembly 4 and reducing the possibility of water leakage from the tank 31.

[0055] like Figure 4 and Figure 5 As shown, the water outlet valve assembly 5 includes a water outlet connector 51, a water outlet pipe, a push rod, a second elastic element 54, and a second sealing element 55. The water outlet connector 51 is located inside the body 1 and fixed to the body 1. The water outlet pipe includes an integrally formed main body 521 and a guide part 522. The guide part 522 extends out of the body 1. The inner diameter of the main body 521 is larger than the inner diameter of the guide part 522. The end of the main body 521 away from the guide part 522 extends into and is fixed inside the main body connector, thus fixing the water outlet pipe. The water outlet end of the purified water pipe 9 passes through the water outlet connector 51 and extends into the main body 521, allowing purified water to flow into the main body 521. A third sealing element 57 is sleeved on the outer peripheral wall of the main body 521. The third sealing element 57 abuts against the inner wall of the water outlet connector 51 to reduce the possibility of water leakage between the water outlet connector 51 and the main body 521. The push rod is slidably disposed inside the water outlet pipe. The push rod includes a sealing section 531 and a water guiding section 532 fixed on the sealing section 531. The sealing section 531 has a water guiding notch 5311, and the water guiding section 532 has a water outlet channel 56. Water can flow through the water guiding notch 5311 and the water outlet channel 56. The second sealing element 55 is fixed on the side of the sealing section 531 facing the water inlet valve assembly 4, and one end of the second elastic element 54 is fixed on the side of the sealing section 531 away from the water inlet valve assembly 4, and the other end is fixed to the water outlet end of the clean water pipe 9. The second sealing element 55 and the third sealing element 57 are both made of silicone material, and the second elastic element 54 is a second spring.

[0056] When the inlet valve assembly 4 and the outlet valve assembly 5 come into contact, the check valve core 42 and the guide section 532 push against each other, causing the guide section 532 and the sealing section 531 to move away from the check valve core 42 and compress the second spring. The purified water flows into the tank 31 through the purified water pipe 9, the guide notch 5311, the outlet channel 56, the inlet channel 45, and the outlet of the inlet connector 41, or flows out of the inlet 2 from inside the tank 31 through the outlet of the inlet connector 41, the inlet channel 45, the outlet channel 56, the guide notch 5311, and the inlet pipe. When the inlet valve assembly 4 and the outlet valve assembly 5 are not in contact, the second spring drives the sealing section 531 and the water guide section 532 to move toward the check valve core 42, so that the water guide section 532 is fully inserted into the guide section 522. At the same time, the second seal 55 is pressed against the guide section 522, and the water flow cannot enter the water guide channel, thereby sealing the water inlet end of the guide section 522 and reducing the possibility of water leakage from the main body 521.

[0057] By cooperating with the inlet valve assembly 4 and the outlet valve assembly 5, the water tank 3 will not leak when it is removed from the body 1. After the water tank 3 is installed on the body 1, the water tank 3 can be connected to the water production module and the water inlet 2, which facilitates the storage of purified water and the intake of water from the water inlet 2, thus improving the user experience.

[0058] like Figure 2 and Figure 6 As shown, the hydrogen production module includes a housing 61 and a hydrogen production unit snapped into the housing 61. The housing 61 is installed at the bottom of the box 31 by multiple screws. The top of the housing 61 is provided with a water inlet 611. The housing 61 is provided with an exhaust port 612 located below the hydrogen production unit. The bottom of the box 31 is provided with a water outlet 311. Water in the box 31 can flow to the hydrogen production unit through the water outlet 311 and the water inlet 611. At the same time, hydrogen produced by the hydrogen production unit can enter the box 31 through the water inlet 611 and the water outlet 311 to form hydrogen-rich water. Oxygen produced by the hydrogen production unit is discharged from the exhaust port 612.

[0059] The hydrogen production unit includes a sealing frame 621, a cathode motor 622, a proton exchange membrane 623, and an anode 624 stacked sequentially from top to bottom. The sealing frame 621 is fitted over the cathode motor 622 and the anode 624 and is secured to the inner wall of the housing 61, ensuring that water inside the housing 61 can only contact the cathode. A power supply male terminal 71 is installed inside the housing 61 and electrically connected to the cathode and anode 624. When the cathode and anode 624 are energized, water at the cathode passes through the proton exchange membrane 623 to the anode 624, where it ionizes to form hydrogen ions, electrons, and oxygen. Oxygen is discharged from the housing 61 through the exhaust port 612, while hydrogen ions and electrons pass through the proton exchange membrane 623 to the cathode, where they form hydrogen gas. The hydrogen gas enters the tank 31 through the water inlet port 611 and the water outlet port 311, forming hydrogen-rich water. Using hydrogen-rich water for drinking or making soup is more beneficial to health.

[0060] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
