一种氮氧分离装置及分离方法A nitrogen and oxygen separation device and separation method 技术领域Technical field

本发明涉及皮肤美容设备技术领域，特别是涉及一种氮氧分离装置及分离方法。The present invention relates to the technical field of skin beauty equipment, and in particular to a nitrogen and oxygen separation device and a separation method.

背景技术Background technique

美容行业现有等离子产生方法，都是在空气环境中，以高频高压高功率电离为主，产生的等离子属于火花放电乃至弧光放电，其温度和功率都很高。在空气中作用于皮肤时，由于急剧发热，造成水分严重流失，组织发生凝固性坏死，甚至碳化或汽化。针对这一技术问题而优化后的技术通常是在低温环境下产生等离子体，作用于皮肤。此方法虽然降低急剧发热概率，一定程度上保护皮肤，但是在空气介质中，等离子体仍然无法达到理想的皮肤治疗效果。如果是在富氧环境或者富氮环境中，等离子体的皮肤治疗效果要明显提高。The existing plasma generation methods in the beauty industry are all based on high-frequency, high-voltage, and high-power ionization in an air environment. The plasma generated belongs to spark discharge or even arc discharge, and its temperature and power are very high. When it acts on the skin in the air, due to rapid heating, it causes serious loss of water, coagulative necrosis of the tissue, and even carbonization or vaporization. Technologies optimized to address this technical problem usually generate plasma in a low-temperature environment and act on the skin. Although this method reduces the probability of rapid heating and protects the skin to a certain extent, plasma still cannot achieve the ideal skin treatment effect in the air medium. If it is in an oxygen-rich environment or a nitrogen-rich environment, the skin treatment effect of plasma will be significantly improved.

传统的氮氧分离装置只能够产生单一气体，如申请号为“201510559015.6”，名称为“氮氧分离装置”的发明专利。如果在传统装置的基础上增加另一种气体的分子筛塔，则会明显提高装置的复杂程度，并且氮氧分离装置使用后通常会进行清洗，两种分子筛塔的清洗过程，也会变得十分繁琐。Traditional nitrogen and oxygen separation devices can only produce a single gas. For example, the application number is "201510559015.6" and the invention patent is named "Nitrogen and Oxygen Separation Device". If a molecular sieve tower of another gas is added to the traditional device, the complexity of the device will be significantly increased, and the nitrogen and oxygen separation device will usually be cleaned after use, and the cleaning process of the two molecular sieve towers will also become very complicated. Cumbersome.
