Description

Technical Field

[0001] The present invention relates to the technical field of direct drinking water systems, and in particular to a hydrogen-rich direct drinking water system and an implementation method thereof. Background Art

[0002] Hydrogen-rich drinking water is obtained by dissolving a small amount of hydrogen in drinking water. It has antioxidant and anti-inflammatory effects, improves energy metabolism, protects the nervous system, and promotes athletic performance. Studies have shown that hydrogen can neutralize active oxygen in the body, reduce oxidative stress, and thus protect cells from damage. At present, hydrogen-rich drinking water is mainly obtained through community direct drinking machines (also known as hydrogen-rich water stations) or large-sized household hydrogen-rich water machines. The difference between them and ordinary direct drinking water machines mainly lies in the addition of a hydrogen-rich system. The appropriate concentration of hydrogen-rich water is between 0.5 and 2.0 PPM. The concentration of hydrogen-rich water products on the market is mostly below 0.8 PPM. The therapeutic effect of hydrogen-rich water with a concentration above 1.0 PPM is significant, while the therapeutic effect below 1.0 PPM is not obvious. It can be seen that the concentration requirements of hydrogen-rich water are different for different groups of people. However, the existing hydrogen-rich direct drinking system does not have the function of adjusting the concentration of hydrogen-rich water. It produces hydrogen-rich water of a fixed concentration, and the operating parameters of the equipment are constant. After long-term operation, the concentration of hydrogen-rich direct drinking water produced will decay. On the other hand, for users, the hydrogen concentration content of hydrogen-rich water obtained by hydrogen-rich water stations or hydrogen-rich water machines cannot be intuitively observed, and users are required to measure it by themselves, which affects the user experience.

[0025] In this embodiment, a mechanism for detecting the hydrogen concentration of hydrogen-rich direct drinking water is provided, namely, a hydrogen-rich direct drinking water hydrogen measuring mechanism, which includes a hydrogen measuring chamber connected to the direct drinking water outlet pipe through a branch pipe, a first solenoid valve arranged on the branch pipe, a drain pipe arranged at the bottom of the hydrogen measuring chamber, a second solenoid valve arranged on the drain pipe, a hydrogen measuring electrode probe arranged at the top of the hydrogen measuring chamber, and a communication module communicating with the control system; the first solenoid valve and the second solenoid valve are controlled by the solenoid valve control module, and the hydrogen measuring electrode probe communicates with the control system through the communication module; wherein, the communication module and the hydrogen measuring electrode probe can be integrated, the connection position of the branch pipe, the drain pipe and the hydrogen measuring chamber is located at the side of the side hydrogen chamber, and the connection position of the branch pipe and the direct drinking water outlet pipe is located at the front side of the outlet solenoid valve, so that when detection is required, the generated hydrogen-rich direct drinking water can first flow into the hydrogen measuring chamber through the cooperation of the outlet solenoid valve and the first solenoid valve. Through the hydrogen-rich direct drinking water hydrogen measuring mechanism, the hydrogen concentration of hydrogen-rich water can be directly detected by the hydrogen-rich direct drinking machine and displayed to the user, without the need for further detection.

[0026] In a further preferred embodiment, a display screen electrically connected to the control system is also included, and the display screen is used to display the pressure value of the variable frequency boosting device, the set concentration of the hydrogen-rich direct drinking water and the detected concentration of the hydrogen-rich direct drinking water, so that when using it, the user can intuitively see the concentration of the hydrogen-rich direct drinking water and the process of its concentration adjustment, etc., thereby improving the user experience.

[0027] Example 2 Reference Figure 2, which is the second embodiment of the present invention, and provides a method for implementing a hydrogen-rich direct drinking water system, comprising the following steps: 1. Step S1: The user sets the hydrogen concentration of hydrogen-rich drinking water, which is recorded as the set concentration C1.

[0028] The user can set the hydrogen concentration through the virtual keyboard of the touch screen or the set physical keyboard.

[0029] Step S2: Control the drinking water system to transport drinking water from the drinking water outlet to the hydrogen mixing device This step is executed by the control system. A corresponding start button or a virtual start button is set on the hydrogen-rich direct drinking machine. When the user presses it, the device can be started.

[0030] 3. Step S3: Control the hydrogen enrichment system to output hydrogen from the hydrogen outlet.

[0031] The hydrogen-rich system is generally a hydrogen production system, such as an electrolysis device. The hydrogen-rich system starts to electrolyze water to produce hydrogen. The control system controls the working pressure of the variable frequency boosting device by controlling the frequency converter, thereby pressurizing the hydrogen. The pressurized hydrogen is then transported to the hydrogen mixing device. The current pressure gauge for the hydrogen pressurization by the variable frequency boosting device is P1. This step is executed by the control system. A corresponding start button or a virtual start button is set on the hydrogen-rich direct drinking machine. The user can start the device by pressing it.

[0032] 4. Step S4: The direct drinking water and the pressurized hydrogen are mixed in a hydrogen mixing device to form hydrogen-rich direct drinking water.

[0033] The hydrogen mixing device can adopt a pressure-bearing tank structure, and is respectively connected to the output end of the variable frequency booster pump and the direct drinking water outlet through pipes; hydrogen and direct drinking water are mixed at the outlet of the hydrogen mixing device to produce hydrogen-rich direct drinking water, and the outlet end of the hydrogen mixing device is connected to the hydrogen-rich direct drinking water outlet pipe; based on the hydrogen-rich direct drinking machine, the hydrogen mixing device is built into the hydrogen-rich direct drinking machine.

[0034] 5. Step S5: Firstly introduce the hydrogen-rich drinking water into the hydrogen measuring chamber.

[0035] In this step, the water outlet solenoid valve and the first solenoid valve are first controlled to open, thereby the hydrogen-rich direct drinking water outlet pipe and the branch pipe are connected, and the hydrogen-rich direct drinking water flows to the hydrogen measuring chamber through the branch pipe. After the hydrogen measuring chamber is full, the water outlet solenoid valve and the first solenoid valve are closed.

[0036] 6. Step S6: The hydrogen measuring electrode probe works and detects the hydrogen concentration of the hydrogen-rich drinking water in the side hydrogen chamber, which is calculated as the detection concentration C2, and the detection result is fed back to the control system.

[0037] The hydrogen measuring electrode probe is fixed on the top of the hydrogen measuring chamber. After the hydrogen measuring chamber is filled with hydrogen-rich drinking water, the hydrogen measuring electrode probe contacts the hydrogen-rich drinking water. The working principle of the hydrogen measuring electrode probe is to detect the quality of hydrogen-rich water by measuring the dissolved hydrogen content in the water. The hydrogen measuring electrode probe is an electrode sensor, usually made of platinum, with a large contact area and stable performance. The electrodes usually use hydrogen electrodes and reference electrodes. The voltage difference between the two electrodes can reflect the concentration of hydrogen-rich ions in the hydrogen-rich water. After the hydrogen measuring electrode probe detects the hydrogen concentration of the hydrogen-rich drinking water in the hydrogen measuring chamber, it feeds the detection results back to the control system.

[0038] 7. Step S7: Compare the set concentration C1 and the detected concentration C2.

[0039] The control system is provided with a set concentration C1 of hydrogen-rich direct drinking water required by the user through a setting module. After receiving the test results, the control system compares the set concentration C1 and the test concentration C2 through a comparison module, and judges whether the concentration of hydrogen-rich direct drinking water meets the standard by the difference between the two. If C1<C2, execute steps S9~S10. If C1>C2, adjust the variable frequency boost device to pressurize the hydrogen. The pressure gauge of the hydrogen pressurized by the adjusted variable frequency boost device is P2. Preferably, P1 and P2 satisfy the following relationship: P2=P1+△P, wherein △P is a set fixed value, which can be an empirical value, set by the staff based on experience.

[0040] 8. Step S8: Repeat steps S4 to S7 until the set concentration C1 ≤ the detection concentration C2.

[0041] After executing this step, considering that hydrogen escapes from water quickly, the hydrogen in the hydrogen-rich direct drinking water will partially escape during the water collection process, thereby reducing the concentration of the hydrogen-rich direct drinking water. Therefore, a pressure compensation step can also be included: set the lower threshold limit of the comparison error between the set concentration C1 and the detection concentration C2 to M, and when M≤C1-C2<0, further increase the working pressure of the variable frequency boost device, and then execute step S9. The lower threshold limit M is a fixed value set by the staff. The principle of the pressure compensation step is that after the detection concentration reaches the set concentration, the hydrogen is further pressurized to increase the solubility of hydrogen in water, so that the concentration of the hydrogen-rich direct drinking water finally discharged from the hydrogen-rich direct drinking water outlet pipe is slightly higher than the set concentration, so as to compensate for the problem of reduced hydrogen concentration in the hydrogen-rich direct drinking water caused by hydrogen escape during the water collection process.

[0042] 9. Drain the hydrogen-rich drinking water in the hydrogen measuring chamber.

[0043] The second solenoid valve is controlled to open to discharge the hydrogen-rich drinking water in the hydrogen measuring chamber. After the discharge is completed, the second solenoid valve is closed. Since the volume of the hydrogen measuring chamber is constant, the water connection and drainage of the hydrogen measuring chamber can be achieved by setting the opening and closing time of the first solenoid valve and the second solenoid valve. For example, after opening the first solenoid valve for 5 seconds, the second solenoid valve is closed to fill the hydrogen measuring chamber. After closing the first solenoid valve, the second solenoid valve is opened for 5 seconds to drain the hydrogen measuring chamber.

[0044] 10. Step S10: Open the water outlet solenoid valve, and the hydrogen-rich direct drinking water outlet pipe outputs hydrogen-rich direct drinking water.

[0045] Through the above settings, users can receive hydrogen-rich direct drinking water that meets the concentration set by the user, and the concentration of hydrogen-rich direct drinking water is directly detected by the equipment without the need for users to conduct additional testing. On the one hand, it ensures that the hydrogen concentration of hydrogen-rich direct drinking water meets the standard. On the other hand, the set concentration C1 of the hydrogen concentration of hydrogen-rich direct drinking water, the detected concentration C2, and the pressure value of the hydrogen pressurized by the variable frequency booster device can be displayed on the display screen. Users can also observe the hydrogen-rich direct drinking water and its working pressure, concentration and other information more intuitively, thereby improving the user experience.

[0046] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
