The present invention relates to the technical field of oxyhydrogen preparation, and in particular to an oxyhydrogen preparation device capable of adjusting hydrogen content and a using method thereof.
Oxygen plays a key role in human metabolism, and hypoxia can cause diseases such as upper respiratory tract infection, insomnia, pulmonary edema, and cerebral edema. In recent years, hydrogen has been widely applied in the fields of medical treatment, health care and health preservation, and people have paid increasing attention to hydrogen-containing gas and hydrogen-containing liquid products. By utilizing the biological effects of hydrogen, such as anti-oxidation, anti-inflammation, anti-apoptosis and cell repair, the effect of improving the physical condition and preventing and treating diseases can be achieved. Many research results show that hydrogen can selectively scavenge malignant free radicals in the body, has health effects such as immune regulation and metabolic regulation, and can be used for auxiliary treatment of cerebral ischemia, senile dementia, lung injury, and kidney injury, as well as for tumor treatment and sleep improvement. In addition, hydrogen has cosmetic effects such as beauty and anti-aging, anti-ultraviolet damage, skin tissue repair, etc. At present, most of the hydrogen generators on the market or hydrogen-oxygen generators in medical institutions have complex structures, and can only achieve the function of preparing high-purity hydrogen or the oxyhydrogen with a fixed hydrogen-oxygen ratio (hydrogen/oxygen=66.6%: 33.3%). However, there has been no report on an oxyhydrogen preparation device capable of adjusting hydrogen content.
Therefore, it is necessary to provide a novel oxyhydrogen preparation device for medical health care and for a user to adjust the hydrogen content to solve the deficiencies in the prior art.
To solve the technical problems of the existing hydrogen and oxyhydrogen production equipment including the complex structure and nonadjustable hydrogen-oxygen ratio, the present invention provides an oxyhydrogen preparation device capable of adjusting hydrogen content and a using method thereof. The present invention mainly applies the process for producing oxygen by air separation to the hydrogen production technology by electrolysis of water, by means of reasonable structural design and optimization of the device, multi-mode supply is realized by controlling and adjusting the gas flow and hydrogen content. The present invention has the advantages of compact structure, long service life, adjustable oxyhydrogen output, and adjustable hydrogen content.

The control module controls the opening and closing of the combined gas valve, allowing the two towers to cycle alternately and continuously to produce high-quality oxygen.
Further, the adsorption device is an adsorption tower group including at least two adsorption towers, a combined gas valve is disposed between the condenser and the adsorption tower group to control gas paths, and the towers of the adsorption tower group circularly and alternately operate based on the pressure swing adsorption principle, so as to separate oxygen from the air. A heat dissipater is further disposed on one side of the condenser, which is configured to dissipate heat from the condenser.

To make the objectives, technical solutions and advantages of embodiments of the present disclosure more obvious, the technical solutions of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present disclosure, and obviously, the described embodiments are some, rather than all of the embodiments of the present disclosure. The following description of at least one example embodiment is merely illustrative in nature, and is in no way intended to limit the present disclosure, an application or use thereof. Based on the embodiments of the present disclosure, all other embodiments acquired by those ordinary skilled in the art without making creative efforts fall within the scope of protection of the present disclosure.
It should be noted that the terms used herein are only intended to describe specific embodiments and are not intended to limit the example embodiments of the present disclosure. As used herein, unless indicated obviously in the context, a singular form is also intended to include a plural form. In addition, it should also be understood that the terms “include” and/or “comprise” used in this specification indicate features, steps, operations, devices, components and/or their combinations.
Except as otherwise specifically set forth, the relative arrangement of components and steps, numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present invention. In addition, it should be clear that, for ease of description, sizes of the various components shown in the accompanying drawings are not drawn according to actual proportional relationships. Technologies, methods, and devices known to those of ordinary skill in the relevant fields may not be discussed in detail, but where appropriate, the technologies, methods, and devices should be considered as a part of the authorization specification. In all the examples shown and discussed herein, any specific value should be interpreted as merely example rather than limiting. Therefore, other examples of the example embodiments may have different values. It should be noted that similar reference signs and letters represent similar items in the accompanying drawings below. Therefore, once an item is defined in one accompanying drawing, the item does not need to be further discussed in a subsequent accompanying drawing.
In the description of the present invention, it should be noted that orientations or position relationships indicated by orientation terms “front, rear, upper, lower, left, and right”, “transverse, vertical, perpendicular, and horizontal”, “top and bottom”, and the like are usually based on orientations or position relationships shown in the accompanying drawings, and these terms are only used to facilitate description of the present invention and simplification of the description. In the absence of description to the contrary, these orientation terms do not indicate or imply that the apparatus or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the protection scope of the present invention: orientation words “inner and outer” refer to the inside and outside relative to the contour of each component.
For ease of description, spatially relative terms such as “on”, “over”, “on the upper surface”, and “above” can be used here, to describe a spatial positional relationship between one device or feature and another device or feature shown in the figures. It should be understood that the spatially relative terms are intended to include different orientations in use or operation other than the orientation of the device described in the figure. For example, if the device in the figure is inverted, the device described as “above another device or structure” or “on another device or structure” is then be positioned as being “below another device or structure” or “beneath a device or structure”. Therefore, the exemplary term “above” can include both orientations “above” and “below”. The device can also be positioned in other different ways (rotating by 90 degrees or in another orientation), and the spatially relative description used herein is explained accordingly.
In addition, it should be noted that using terms such as “first-stage” and “second-stage” to define components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the foregoing words have no special meaning and therefore cannot be understood as a limitation on the protection scope of the present invention.
