Detailed Description
Fig. 1 is a schematic side view of a molecular hydrogen generator according to an embodiment of the present invention. Fig. 2 is a schematic front view of a molecular hydrogen generator according to an embodiment of the present invention. Fig. 3 is a schematic side view of a molecular hydrogen generator according to another embodiment of the present invention. Fig. 4 is a schematic front view of a molecular hydrogen generator according to another embodiment of the present invention. In one embodiment, a molecular hydrogen generator includes an oxyhydrogen electrolysis assembly 10, a first water tank 20, and a second water tank 30. The oxyhydrogen electrolysis assembly comprises a body 11, a water inlet 12, a hydrogen production outlet 13 and an oxygen production outlet 14. The body 11 includes a first side 110 and a second side 112 opposite to each other, wherein the hydrogen generating port 13 is located at an upper half of the first side 110, the oxygen generating port 14 is located at an upper half of the second side 112, and the water inlet 12 is located at a lower half of the second side 112. After water enters the hydrogen-oxygen electrolysis assembly 10 from the water inlet 12, hydrogen ions are reduced at the cathode to generate hydrogen, and hydroxide ions are oxidized at the anode to generate oxygen, and then are discharged from the hydrogen outlet 13 and the oxygen outlet 14, respectively. In some embodiments, the molecular hydrogen generator includes a current supply 75 to provide sufficient power to the hydrogen-oxygen electrolysis assembly 10 for the water electrolysis function. For example: a model PC300w SFX power supply was used. As can be seen from the above, the molecular hydrogen generator of the present invention can supply not only hydrogen but also oxygen and pure water.
Referring to fig. 1 and 3, the first housing 21 of the first water tank 20 has a first accommodating space (not shown) for storing water, and the second housing 31 of the second water tank 30 has a second accommodating space (not shown). In some embodiments, the maximum water storage capacity of the first or second receiving space may be between 200cc and 500 cc. In some embodiments, the first housing 21 and the second housing 31 may be made of plastic, rubber, metal (such as stainless steel) or other food grade safe materials, but not limited thereto.
With continued reference to fig. 1, 2, 3 and 4, the first tank 20 includes a first housing 21 and a first liquid level monitoring element 22. The first liquid level monitoring device 22 is used for detecting a low water level in the first accommodating space, so that the water level in the first accommodating space is kept above the low water level, and the malfunction of the oxyhydrogen electrolysis assembly 10 caused by water shortage can be avoided. The water level in the water tank is kept higher than the low water level to maintain the humidity in the hydrogen-oxygen electrolysis assembly 10, so as to avoid the over-drying and damage of the reaction membrane in the hydrogen-oxygen electrolysis assembly and reduce the service life of the hydrogen-oxygen electrolysis assembly. For example, the low water level means that the water storage capacity of the first accommodating space is at least 150 cc. The second liquid level monitoring element 32 is used for detecting a high water level in the second accommodating space, so that the water level in the second accommodating space is kept below the high water level, and the water is prevented from overflowing excessively. For example, the high water level means that the water storage capacity of the second accommodating space cannot be more than 450 cc.
In some embodiments, the first liquid level monitoring element 22 can detect the complete water storage capacity of the first accommodating space at any time, and the second liquid level monitoring element 32 can detect the complete water storage capacity of the second accommodating space at any time, rather than detecting only the high water level or the low water level. For example, the first and second liquid level monitoring elements 22 and 32 may include high and low water level detection points, respectively. In some embodiments, the molecular hydrogen generator includes a display screen (e.g., LCD, LCM touch screen) to display the water storage capacity of the first water tank 20 or the second water tank 30 on the display screen in real time, or to display only the total water storage capacity in the first accommodating space and the second accommodating space, so that the user can know the total water volume at any time. In some embodiments, the first tank 20 includes a filling hole 29, the filling hole 29 may be provided on an upper top surface of the first tank 20, and the filling hole 29 may have a cover. When the first liquid level monitoring device 22 detects that the water level in the first accommodating space is close to or reaches the low water level, it will transmit a warning signal (flashing light, warning sound, etc.) to indicate to the user that the user should add insufficient water into the first water tank 20. In this way, the display screen and the warning signal can be arranged on the surface of the shell of the molecular hydrogen generator.
In some embodiments, the first liquid level monitoring element 22 of the molecular hydrogen generator is disposed on the outer surface of the first housing 21, and the second liquid level monitoring element 32 is disposed on the outer surface of the second housing 31. For example, the liquid level monitoring element may be a non-contact liquid level sensor, which detects whether liquid exists by using a sensing capacitance of water, and is not easily damaged by being immersed in the liquid.
Referring to fig. 1, 2, 3 and 4, in some embodiments, the first housing 21 further includes a first air receiving hole 23, a first air discharging hole 25 and a first water outlet hole 24. The first air receiving hole 23 and the first water outlet hole 24 are disposed at a position below the low water level on the first casing 21 to ensure that the hydrogen-oxygen electrolysis assembly 10 can continuously obtain water from the first water outlet hole 24. The first gas containing hole 23 is communicated with the oxygen gas outlet 14 of the oxyhydrogen electrolysis assembly 10. The first water outlet hole 24 is communicated with the water inlet hole 12 of the oxyhydrogen electrolysis assembly 10. The first exhaust hole 25 is disposed at a position above the low water level on the first housing, so that oxygen entering from the first exhaust hole 25 can pass through at least a part of water and then be dissipated to the upper portion of the first accommodating space from the water surface. In other embodiments, the first liquid level monitoring device 22 is used for detecting a high water level and a low water level in the first accommodating space, so that the water level in the first accommodating space is maintained between the high water level and the low water level, the first air receiving hole 23 and the first water outlet hole 24 are located at the low water level, and the first air outlet hole 25 is located above the high water level, thereby further ensuring that water cannot escape from the first air outlet hole 25.
With continued reference to FIGS. 1, 2, 3 and 4, the first water tank 20 is disposed adjacent to the second side 112 of the hydrogen-oxygen electrolysis assembly 10 such that the first gas receiving hole 23 is in communication with the oxygen gas outlet 14. The high temperature and high humidity oxygen generated from the hydrogen-oxygen electrolysis assembly 10 entering the first water tank 20 through the first nano-air hole 23 must pass through the water stored in the first water tank 20 to reach the first air outlet hole 25. Therefore, the high-temperature and high-humidity oxygen is cooled by the water stored in the first water tank 20, a part of moisture in the high-temperature and high-humidity oxygen is retained in the water, the humidity of the oxygen dissipated from the water surface is low, and the cooled and dehumidified oxygen enters the upper part (above the high water level, i.e., the anhydrous part) of the first accommodating space and is then discharged through the first vent 25. In some embodiments, the first vent hole 25 is located at an upper surface of the first water tank 20.
Referring to fig. 1, 2, 3 and 4, the second housing 30 further includes a second air receiving hole 33, a second air outlet hole 35 and a second water outlet hole 34. The second air receiving hole 33 and the second water outlet hole 34 are disposed at a position below the high water level of the second housing 31, and the second air outlet hole 35 is disposed at a position above the high water level of the second housing 31. In other embodiments, the second liquid level monitoring device 32 is used for detecting another high water level and another low water level in the second accommodating space so as to keep the water level in the second accommodating space between the another high water level and the another low water level, the second air receiving hole 33 and the second water outlet hole 34 are located at the another low water level, and the first air outlet hole 35 is located above the another high water level. In some embodiments, a communication pipe may be included between the first tank 20 and the second tank 30, and one end of the communication pipe is connected to the second outlet hole 34, so that when the second liquid level monitoring element 32 detects that the water amount in the second receiving space approaches or reaches a high water level, the stored water in the second tank 30 can flow to the first tank 20 through the communication pipe. In some embodiments, the communication line between the first tank 20 and the second tank 30 may further include a pump to provide power to move the stored water in the second tank 30 to the first tank 20. In some embodiments, the communication line may include a solenoid valve to prevent water in the first tank 20 from flowing back to the second tank 30, or to adjust the amount of water between the two tanks to maintain a uniform amount of water. The solenoid valve may be a normally open solenoid valve.
The second water tank 30 is disposed on the first side 110 of the hydrogen-oxygen electrolysis assembly 10 such that the second gas receiving hole 33 is in butt joint with the hydrogen generation port 13. The hydrogen-oxygen electrolysis assembly 10 produces high-temperature and high-humidity hydrogen gas when electrolyzing water, i.e. a mixture of high-temperature hydrogen molecules and high-temperature water vapor molecules. When the high-temperature and high-humidity hydrogen gas enters the second water tank 30 through the second nano-air hole 33, the water stored in the second water tank 30 must pass through to reach the second air outlet hole 35. Therefore, the high-temperature and high-humidity hydrogen is cooled by the water stored in the second water tank 30, that is, the high-temperature water vapor molecules are cooled to become water molecules and mixed into the water stored in the second water tank 30, and the remaining low-temperature hydrogen molecules are released through the first vent hole 35, so as to be utilized by a user. In some embodiments, a dedicated pipeline (not shown) is disposed between the second gas receiving hole 33 and the second gas vent 35, the dedicated pipeline is disposed in the second accommodating space, and the high-temperature and high-humidity hydrogen generated by the hydrogen-oxygen electrolysis assembly 10 during water electrolysis is released from the dedicated pipeline after flowing from the second gas receiving hole 33 to the second gas vent 35 without contacting water. In some embodiments, the dedicated pipeline may be made of metal, so that the hydrogen gas with high temperature and high humidity can have the effect of cooling or dehumidifying when passing through the dedicated pipeline made of metal. In some embodiments, the molecular hydrogen generator further comprises a water-blocking and air-permeable component disposed outside the first vent 25 or the second vent 35 for further removing moisture in the hydrogen gas or the oxygen gas and keeping the water in the first water tank 20 or the second water tank 30. In some embodiments, the water-blocking breathable component may be implemented by a water-blocking, waterproof, breathable membrane.
Fig. 5 is a schematic perspective view of a molecular hydrogen generator according to an embodiment of the present invention. In some embodiments, the outer surface of the first housing 21 of the first water tank 20 of the molecular hydrogen generator includes a first adjacent plane 212, the first outlet hole 24 is located at a portion of the first adjacent plane 212 close to the bottom surface (i.e., below the low water level), and the first adjacent plane 212 is close to the second side 212 of the hydrogen-oxygen electrolysis assembly, so that the first outlet hole 24 is correspondingly connected to the water inlet 12. In some embodiments, the first nano-gas hole 23 is also located on the first abutting plane 212, and the first nano-gas hole 23 is communicated with the oxygen generating port 14. Herein, referring to the case of the molecular hydrogen generator shown by the dotted line 1 in fig. 5, the dotted line 1 is substantially cylindrical, and since the oxyhydrogen electrolysis component 10, the first water tank 20 and the second water tank 30 are the components with the largest internal volume of the molecular hydrogen generator, the embodiment of the present invention can achieve the reduction of the overall volume of the molecular hydrogen generator and the optimal space utilization rate by proper position arrangement. For example, the molecular hydrogen generator has a circular shape with an outer diameter of 150mm and a height of 150 mm. In addition, according to the arrangement of fig. 5, the molecular hydrogen generator may be designed to have a cubic shape, for example, a shape having a height of 200mm, a width of 150mm, and a depth of 125 mm.
Fig. 6 is a schematic perspective view of a molecular hydrogen generator according to another embodiment of the present invention. In some embodiments, the outer surface of the second housing 31 of the second water tank 30 of the molecular hydrogen generator comprises a second abutting plane 312, the second gas containing hole 33 is located on the second abutting plane 312, and the second abutting plane 312 is adjacent to the first side 110 of the hydrogen-oxygen electrolysis assembly 10, so that the second gas containing hole 33 is correspondingly connected to the hydrogen gas generating outlet 13. Here, a broken line 2 in fig. 6 shows a schematic case of the molecular hydrogen generator, and the broken line 2 has a substantially book-like shape. Referring to FIGS. 1, 2 and 6, for example, the molecular hydrogen generator has a shape of 75mm thick, 200mm wide and 250mm high, and the total weight is 3-6 kg.
Fig. 7 is a schematic perspective view of a molecular hydrogen generator according to another embodiment of the present invention. In some embodiments, the molecular hydrogen generator further includes a third water tank 40 disposed adjacent to the first water tank 20, the third water tank 40 includes a third housing 41, the third housing 41 has a third accommodating space (not shown), the third housing 41 has a third outlet 42, the third outlet 42 is disposed below a low water level of the third housing, and the third outlet 42 is similar to the third accommodating space and is communicated with the first accommodating space. In this way, the stored water in the first water tank 20 and the third water tank 40 can circulate with each other, thereby achieving the effect of increasing the stored water amount. In some embodiments, the first tank 20, the second tank 30, and the third tank 40 have the same maximum water storage capacity. In some embodiments, the first housing 21, the second housing 31 and the third housing 41 have the same or symmetrical shape, so that the same mold is used for manufacturing, thereby saving the manufacturing cost. In some embodiments, the third water tank 40 further includes a third air receiving hole 43 and a third air discharging hole 45, and the third air receiving hole 43 connects the upper half portion (above high water level, water-free area) of the first accommodating space to the upper half portion (above high water level, water-free area) of the third accommodating space. Herein, oxygen generated when the oxyhydrogen electrolysis assembly 10 electrolyzes water enters the first water tank 20 through the first air receiving hole 23 and is collected in the upper half of the first accommodating space, and then enters the upper half of the third accommodating space through the third air receiving hole 43, and is released through the third air vent 45. In some embodiments, the vent may be connected to a multi-angle vent head to provide convenience to the user.
Fig. 8 is a schematic perspective view of a molecular hydrogen generator according to still another embodiment of the present invention. In some embodiments, the third air receiving hole 43 of the third water tank 40 connects the upper half (water-free area) of the first accommodating space to the lower half (water-containing area) of the third accommodating space.
