Detailed ways

In order to make the advantages, spirit and characteristics of the present invention more easily and clearly understood, the following will be described and discussed in detail with reference to the accompanying drawings. It should be noted that these embodiments are only representative embodiments of the present invention, and the specific methods, devices, conditions, materials, etc. cited therein are not intended to limit the present invention or the corresponding embodiments.

Please refer to FIG. 1 , which shows a three-layer air-water circulation system according to some embodiments of the present invention, wherein the electrolyzer is a sheet-type electrolyzer. According to some embodiments of the present utility model, the air-water circulation system 100 includes an electrolytic tank 110 for containing electrolyzed water 112. The main component of the electrolyzed water 112 is pure water or water, and a small amount of electrolyte can be added as needed, such as hydroxide Sodium, calcium carbonate, sodium chloride, etc. In this embodiment, the electrolytic cell 110 is a sheet-type electrolytic cell, which includes a plurality of sheet-type electrodes 114 , through which the electrolyzed water 112 can be electrolyzed to generate hydrogen-oxygen gas 116 containing hydrogen and oxygen. Since the hydrogen and oxygen gas 116 will precipitate out of the upper part of the electrolytic cell 110 , the electrolytic cell 110 of the present invention is provided with a first gas outlet 118 at the upper part, which can lead out the generated hydrogen and oxygen gas 116 . The electrolyzed water 112 in the electrolyzed tank 110 is consumed due to electrolysis, so the electrolyzed tank 110 also includes a first water inlet 120 for replenishing pure water, which can be located at the bottom of the electrolyzed tank 110 as shown in the figure.

The first water storage tank 122 is used for containing pure water 124 for replenishing the electrolytic cell 110 . The first water storage barrel 122 is configured with a gas inlet 126 coupled with the first gas outlet 118 of the electrolytic cell 110 by a pipeline. The gas inlet 126 can pass the hydrogen and oxygen gas 116 produced by the electrolytic cell 110 into the pure water 124 of the first water storage tank 122. At this time, only a small part of the hydrogen and oxygen gas 116 is dissolved in the pure water 124, and most of the hydrogen and oxygen gas 116 will be dissolved in the pure water 124. The surface of the pure water 124 floats out, that is, the upper part of the first water storage tank 122 . However, during the surface process of hydrogen and oxygen gas 116 from the bottom of pure water 124, due to the high specific heat of pure water 124, most of the heat energy can be absorbed, and the temperature of hydrogen and oxygen gas 116 is reduced to make it close to the temperature of pure water 124, such as room temperature (25 Degree C). Thereby, the chance of hydrogen explosion generated by the hydrogen and oxygen gas 116 can be reduced, and the safety of the system can be improved. In one embodiment, the gas inlet 126 is located on the outer wall of the lower half of the gas inlet 126 , as shown in FIG. 1 , generally as long as the gas inlet 126 is lower than the water level of the first water storage bucket 122 in normal use. At the same time, the pure water 124 can also dissolve a small amount of unnecessary electrolytic gas in the hydrogen and oxygen gas 116 , such as chlorine gas, and also has a filtering effect. The first water storage bucket 122 also includes a first water outlet 128, for example, disposed at the bottom of the first water storage bucket 122, and is coupled with the first water inlet 120 of the electrolytic cell 110 with a pipeline, so that the first water storage bucket 122 can be Pure water 124 is introduced into the electrolytic cell 110 for replenishment. The first water storage bucket 122 is preferably configured slightly higher than the electrolytic tank 110 (as shown in Figure 1, the bottom of the first water storage bucket 122 is higher than the top of the electrolytic tank 110, or the bottom of the first water storage bucket 122 is higher than the top of the electrolytic tank 110 Just the bottom, for example, the bottom of the first water storage bucket 122 is higher than the position of 1/4 from the bottom of the electrolytic tank 110), at this time, the electrolytic tank can be adjusted by the siphon principle or the gravity principle without other pressurizing equipment. 110 automatic water replenishment. In addition, since hydrogen and oxygen gas 116 is introduced into the first water storage tank 122, it will also generate pressure on the pure water 124 or the surface of the water in the first water storage tank 122, and this pressure can also prompt the first water storage tank 122 to automatically replenish water to the electrolytic cell 110. .

The oxygen gas 116 cooled and filtered by the pure water 124 will be stored in the upper part of the first water storage tank 122 and exported through the second gas outlet 130 on the upper part for inhalation by the user. At this time, the flow rate of the oxygen gas 116 can be between 0.1L /min～2L/min. The pressure relief device 132, such as a pressure relief valve, is arranged on the upper part of the first water storage tank 122. When the hydrogen and oxygen gas 116 stored in the upper part of the first water storage tank 122 exceeds a preset pressure, the pressure can be released through the pressure relief device 132. , so hydrogen explosion can be prevented, that is to say, the pressure relief device can selectively release pressure on the first water storage tank. For example, when the discharge of the second gas outlet 130 is abnormal, such as blockage, etc., since the electrolytic cell 110 continues to produce hydrogen and oxygen gas 116, the amount of hydrogen and oxygen gas in the first water storage tank 122 will increase, and the pressure will increase. The pressure relief through the pressure relief device 132 can prevent hydrogen explosion. In one embodiment, the pressure relief can be performed when the pressure is set to be at atmospheric pressure (1 Pa). The first water storage tank 122 further includes a first water level detector 134 for detecting the water level of the pure water in the first water storage tank 122 , and its function will be described in detail later.

And when the first water storage tank 122 continues to replenish the pure water 124 to the electrolytic cell 110, it means that the production of hydrogen and oxygen gas 116 also increases, and the hydrogen and oxygen gas 116 stored in the upper part of the first water storage tank 122 increases, so the pure water 124 in the first water storage tank 122 The water level is lowered. If the amount of hydrogen and oxygen gas 116 is too high, it is easy to produce hydrogen explosion, so the water level detection by the first water level detector 134 can maintain a small amount of hydrogen and oxygen gas 116 in the first water storage tank 122 . Therefore, the above-mentioned depressurization and replenishment of pure water can effectively control the storage volume and pressure of the hydrogen and oxygen gas 116 in the first water storage tank 122, and can effectively prevent hydrogen explosion.

In another embodiment, when the first water level detector 134 detects that the water level of the pure water 124 in the first water storage tank 122 is lower than a preset value, the liquid valve 142 is opened, so that the first water storage tank 122 passes through the second storage tank. When the water bucket 136 is replenished with pure water 124 , the pressure relief device 132 can also be released at the same time to increase safety. That is to say, the first water level detector 134 can selectively activate the pressure relief device 132 . At this time, the opening time of the pressure relief device 132 and the liquid valve 142 will overlap. In another embodiment, the second water storage bucket 136 is preferably configured slightly higher than the first water storage bucket 122 (as shown in Figure 1, the bottom of the second water storage bucket 136 is higher than the top of the first water storage bucket 122, or The bottom of the second water storage bucket 136 can be higher than the bottom of the first water storage bucket 122, for example, the bottom of the second water storage bucket 136 is higher than the position of 1/4 from the bottom of the first water storage bucket 122), when the liquid valve 142 is opened, it can be borrowed. Based on the siphon principle or the gravity principle, the first water storage tank 122 can be automatically replenished with water without other pressurization or pump equipment.

The second water storage barrel 136 is also equipped with a second water level detector 144 to detect the safe low water level of the pure water 124 (or electrolyzed water) in the second water storage barrel 136 ; and is equipped with a second water injection port 146 . When the second water level detector 144 detects that the water level of the pure water 124 (or electrolyzed water) is lower than a preset low water level value, the second water level detector 144 will have a warning light to inform the user to pass through the second water injection port. 146 can replenish pure water 124, and of course also can turn off the power supply of electrolyzer at this moment and wait for the user to replenish pure water 124 through the second water injection port 146 and then restart the power supply of electrolyzer. The second water level detector 144 of the second water storage bucket 136 can also detect the safe high water level of the pure water 124 in the second water storage bucket 136, when the user fills the second water storage bucket 136 to make the water level higher than a preset height When the water level is reached, the second water level detector 144 will have a warning light to light up to notify the user that the water filling can be stopped.
