Abstract

This invention discloses a hydrogen-rich water preparation system, a smart toilet seat, a smart toilet, and a hydrotherapy enema method, relating to the field of hydrogen-rich water production and preparation technology. The hydrogen-rich water preparation system includes a water circuit component and an electrical control component. The water circuit consists of a filter, a solenoid valve, an electrolytic cell, a heater, and a distribution valve connected in series. The distribution valve divides the water into two paths: one for hydrogen-rich water enema and the other connected to an external faucet for external use. The electrical control component uses a controller to centrally manage all water circuit components. The system can be integrated into a smart toilet seat or a smart toilet unit. This invention first filters tap water to inhibit scale buildup, then electrolyzes it to generate ≥400 PPb hydrogen-rich water. After being kept at a constant temperature of 37°C, the water is pressurized and injected into the large intestine, automatically shutting off after 2 minutes. This invention's pre-filter prevents scale buildup in the water circuit, and the hydrogen-rich water directly acts on the intestines, offering advantages such as good efficacy, economy, safety, and no side effects, allowing for long-term use.

Description

Technical Field

[0001] This invention relates to the field of hydrogen-rich water production and preparation technology, and in particular to a hydrogen-rich water preparation system, a smart toilet seat, a smart toilet, and a hydrotherapy enema method. Background Technology

[0002] Extensive scientific research and clinical practice have proven that hydrogen-rich water, infused with dissolved hydrogen, possesses health benefits such as anti-inflammatory and intestinal health maintenance. In February 2026, the Ministry of Civil Affairs included hydrogen-rich water supply devices in its catalog of personal medical assistive devices. Currently, the mainstream methods of hydrogen-based health maintenance are hydrogen inhalation and drinking hydrogen-rich water. However, both methods have significant drawbacks: hydrogen gas and orally ingested hydrogen-rich water are neutralized by stomach acid after entering the stomach, preventing the hydrogen from reaching the large intestine and hindering targeted intestinal regulation.

[0003] In existing technologies, the Hydrogen Science Center of Shanghai Jiao Tong University has developed magnesium hydride sustained-release capsules. The capsules can pass through the stomach to reach the intestines and hydrolyze to produce hydrogen, which can improve intestinal inflammation. However, this approach has many drawbacks: First, it requires long-term purchase of capsule consumables, resulting in high usage costs; second, magnesium hydride hydrolyzes to produce magnesium hydroxide, which can easily cause bloating, diarrhea, and magnesium ion accumulation with long-term use; and third, there is a risk of magnesium poisoning in people with renal insufficiency, making it unsuitable for long-term use.

[0004] Conventional smart toilets and toilet seats only offer warm water washing and lack an integrated structure for hydrogen-rich water preparation and intestinal enema. Using an external, separate hydrogen-rich water device for enemas results in cluttered piping, space-consuming operations, and complicated procedures. Directly using untreated tap water for hydrogen production via electrolysis easily leads to scale buildup that clogs the electrolysis cell and water lines. Currently, there is no commercially available integrated hydrogen-rich water preparation solution that simultaneously provides intestinal enema therapy and external hydrogen-rich water supply, while also being compact and integrated into the bathroom unit. Summary of the Invention

[0005] The main objective of this invention is to provide a hydrogen-rich water preparation system, a smart toilet seat, a smart toilet, and a hydrotherapy enema method to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention provides a hydrogen-rich water preparation system, including a water circuit component and an electrical control component; The water circuit assembly includes a filter, a solenoid valve, an electrolytic cell, a heater, a distribution valve, a water pump, a reversing valve, a hydrotherapy tube, and a hydrotherapy head, which are connected in sequence through pipelines. The inlet end of the filter is connected to a tap water pipe. The electrical control components include a controller and a control panel; the solenoid valve, electrolytic cell, heater, distribution valve, water pump, reversing valve and control panel are all electrically connected to the controller.

[0007] Furthermore, the water circuit assembly also includes an internal connecting pipe, a connector, an external connecting pipe, and a faucet with a switch; one end of the internal connecting pipe is connected to the other outlet of the distribution valve, and the other end is connected to the connector; one end of the external connecting pipe is connected to the connector, and the other end is connected to the faucet.

[0008] Furthermore, the control panel is equipped with a spa button and a hydrogen-rich water tap button.

[0009] Furthermore, a disposable spa head cover is installed on the spa head.

[0010] The present invention also provides a smart toilet seat, including the above-mentioned hydrogen-rich water preparation system.

[0011] The present invention also provides a smart toilet, including the above-mentioned smart toilet seat or hydrogen-rich water preparation system.

[0012] The present invention also provides a hydrotherapy enema method using the above-mentioned hydrogen-rich water preparation system, comprising the following steps: S1. Pretreatment: Tap water is sent through the tap water pipe into a special filter to complete scale inhibition filtration; S2. Start the equipment: Press the spa button, and the controller will synchronously drive the solenoid valve, electrolytic cell, heater, distribution valve, water pump, and reversing valve to work. S3. Hydrogen-rich water produced by flowing electrolysis: Filtered tap water continuously flows through the electrolysis cell, and hydrogen-rich water with a hydrogen content of ≥400PPb is generated during the flow process. S4. Constant temperature treatment: Hydrogen-rich water is passed into a constant temperature heater and heated to 37°C; S5, pressurized enema water supply: The distribution valve opens the enema branch, and the hydrogen-rich water is pressurized to 0.3MPa by the water pump. It is then delivered to the hydrotherapy head through the reversing valve and hydrotherapy tube and injected into the user's colon. S6. Automatic shutdown: The controller will cut off the power and stop the water supply after 2 minutes of timing. The total amount of hydrogen-rich water output in a single cycle is 1.7L.

[0013] Furthermore, it also includes the steps for external use of hydrogen-rich water: Press the button on the hydrogen-rich water faucet, the controller switches the distribution valve to the external branch, and the constant temperature hydrogen-rich water is delivered to the faucet through the internal connecting pipe, connector, and external connecting pipe. Turn on the switch on the faucet to output hydrogen-rich water for washing your face, brushing your teeth, or soaking your feet.

[0014] The present invention has the following beneficial effects: 1. This invention delivers hydrogen-rich water directly to the large intestine to exert its therapeutic effect. Unlike oral hydrogen products, it is not neutralized by stomach acid. Furthermore, the entire process involves electrolyzing tap water to produce hydrogen, with no added chemical agents. Therefore, it does not have side effects such as magnesium accumulation, diarrhea, or kidney damage, and can be used safely for a long time.

[0015] 2. The inlet filter of this invention prevents scale buildup in advance, effectively avoiding scale buildup and blockage in the electrolytic cell and pipelines, and extending the service life of the equipment.

[0016] 3. The entire system is modularly integrated into the smart toilet seat or smart toilet body, eliminating the need for additional consumables. The overall structure is compact, requiring only periodic filter replacement, resulting in low daily operating costs.

[0017] 4. The distribution valve is equipped with dual independent water circuits, which can perform constant temperature and pressurized intestinal hydrotherapy, and can also be connected to an external faucet to output hydrogen-rich water for washing face, soaking feet, and brushing teeth. One machine can realize multiple uses for physiotherapy and daily health care, making the equipment more efficient.

[0018] 5. All components are centrally controlled by the controller, which can automatically maintain the temperature at a comfortable 37°C and stably pressurize to 0.3MPa. The hydrotherapy mode automatically stops after 2 minutes and the water output is fixed per session. The operation is fully automatic and the user experience is comfortable. It comes with a disposable hydrotherapy head cover, which effectively prevents cross-infection when multiple people use it, making it more hygienic.

[0019] 6. The product is highly adaptable. It can be integrated separately into a smart toilet seat for use with a regular toilet, or it can be directly integrated into a complete smart toilet unit for shipment. It is suitable for both new product production and old bathroom renovation scenarios, and has a wide range of applications. Attached Figure Description

[0027] The water circuit components include a filter 1, a solenoid valve 4, an electrolytic cell 5, a heater 6, a distribution valve 7, a water pump 8, a reversing valve 9, a spa tube 10, a spa head 12, a disposable spa head cover 11, an internal connecting pipe 15, a connector 16, an external connecting pipe 17, and a faucet 18 with a switch 19. The inlet of filter 1 is directly connected to the tap water pipe 13. The outlet of filter 1, solenoid valve 4, electrolysis cell 5, heater 6, distribution valve 7, water pump 8, reversing valve 9, hydrotherapy pipe 10, and hydrotherapy head 12 are connected in series through the pipeline along the water flow direction. A disposable hydrotherapy head cover 11 can be detachably installed on the outside of hydrotherapy head 12.

[0028] The distribution valve 7 has two water outlet channels: Channel 1 (Enema Branch): Distributor Valve 7 → Water Pump 8 → Reversing Valve 9 → Hydrotherapy Tube 10 → Hydrotherapy Head 12; Channel 2 (External Branch): Another outlet of the distribution valve 7 is connected to the internal connecting pipe 15. The internal connecting pipe 15 is connected to the external connecting pipe 17 through the connector 16. The end of the external connecting pipe 17 is equipped with a faucet 18, which has a built-in control switch 19.

[0029] The electrical control components include a controller 3 and a control panel; the control panel is equipped with a spa button 2 and a hydrogen-rich water tap button 14; the controller 3 is electrically connected to the solenoid valve 4, electrolysis cell 5, heater 6, distribution valve 7, water pump 8, reversing valve 9, and control panel.

[0030] Functional descriptions of each core component

[0031] ①Filter 1: Scale-inhibiting filter, pre-treats tap water, removes calcium and magnesium ions from the water, and prevents scale from clogging the water passages during the electrolysis process in the electrolysis tank 5 and pipelines. ② Electrolyzer 5: Flow electrolysis structure. When water flows continuously through the electrolyzer, it is electrolyzed to produce hydrogen and oxygen. The hydrogen dissolves in the water to prepare hydrogen-rich water with a hydrogen content ≥400 PPb. ③ Heater 6: Constant temperature heating component with built-in temperature control chip, which stably heats the flowing hydrogen-rich water to the human body temperature of 37℃; ④ Distribution valve 7: Dual-pass switching valve, controlled by controller 3, selects one to connect the enema branch or the external use branch; ⑤ Pump 8: Booster pump, which increases the water pressure in the water circuit from the conventional tap water pressure of 0.1MPa to 0.3MPa, ensuring a gentle and stable flow of water for enema. ⑥ Reversing valve 9: Normally closed outlet valve body. In enema mode, the controller controls the reversing valve 9 to open and connect the water to the hydrotherapy pipe 10. ⑦ Disposable spa headgear 11: Detachable soft rubber parts, replaceable after single use, improving the hygiene of intestinal physiotherapy; ⑧ Controller 3: The core of the whole machine control, with a built-in timing module. After pressing the spa button 2, it will automatically start a 2-minute timer. When the timer ends, it will cut off the power to all components and stop the whole machine from supplying water. ⑨ Faucet 18 and switch 19: External hydrogen-rich water outlet. After the water circuit is connected, the switch can be manually turned on to flow out hydrogen-rich water.

[0039] Example 5: Hydrotherapy Enema Method

[0040] This method is based on the hydrogen-rich water preparation system described in the above embodiments, and includes an intestinal enema physiotherapy process and a hydrogen-rich water external application diversion process.

[0041] Procedure 1: Colonic hydrotherapy enema steps

[0042] S1. Pretreatment: Municipal tap water is sent into filter 1 through tap water pipe 13. Filter 1 completes scale inhibition filtration of water quality and eliminates ions that are prone to scale formation. S2. Start the equipment: When the user presses the spa button 2 on the control panel, the controller 3 receives the electrical signal and synchronously drives the solenoid valve 4, electrolytic cell 5, heater 6, distribution valve 7, water pump 8, and reversing valve 9 to start synchronously. S3. Hydrogen-rich water produced by flowing electrolysis: Filtered tap water continuously flows through electrolysis cell 5. During the water flow, hydrogen is generated by electrolysis and fully dissolved in the water to produce hydrogen-rich water with a hydrogen content ≥400PPb. S4. Constant temperature treatment: Hydrogen-rich water flows into heater 6, and the heater controls the temperature in real time to heat the water to 37°C. S5, pressurized enema water supply: Controller 3 controls the distribution valve 7 to open the enema branch, and constant temperature hydrogen-rich water enters the water pump 8 to complete the pressurization, and the water pressure is increased to 0.3MPa; the water flows through the reversing valve 9 and the hydrotherapy pipe 10 in sequence, and is delivered to the hydrotherapy head 12 equipped with the hydrotherapy head cover 11. The user aligns the hydrotherapy head cover with the anus, and the warm hydrogen-rich water is directly injected into the large intestine. S6 Automatic shutdown: The controller 3 has a built-in timing program. After pressing the spa button 2 for 2 minutes, the controller cuts off the power supply to all electrical components and the whole machine stops supplying water. The total capacity of hydrogen-rich water output for a single therapy session is 1.7L.

[0043] Step 2: External Application of Hydrogen-Rich Water

[0044] Press the hydrogen-rich water faucet button 14 on the control panel, and the controller 3 switches the water path of the distribution valve 7 to the external branch. The process of tap water pretreatment, electrolysis to produce hydrogen-rich water, and constant temperature heating is exactly the same as S1~S4. After constant temperature, the hydrogen-rich water is delivered to the faucet 18 through the internal connecting pipe 15, the connector 16, and the external connecting pipe 17. Manually turn on the switch 19 on the faucet 18 to get constant temperature hydrogen-rich water, which can be used for daily health care scenarios such as washing your face, brushing your teeth, and soaking your feet.
