Description

产生负氧离子用的电极及使用该电极的负氧离子发生机 技术领域：
本发明涉及一种产生负氧离子用的电极及使用该电极的负氧离子发生机。
背景技术：
目前负氧离子发生机通常直接采用柱状或针状金属针作为产生负氧离子用的电极，负氧离子产率的高低及臭氧分子产生的水平取决于施加到金属电极上的电压高低，过高的负高压不仅易于产生负氧离子，则更有易于产生臭氧分子，人体吸取过多臭氧易中毒，另外，金属针尖端容易氧气，失去尖端放电作用。为降低臭氧分子的产率，目前，许多负氧离子发生机在每一根金属线或针状金属电极表面包裹几万至几十万根的碳纤维或富勒烯纤维用作发射电极，这种结构的发射电极虽一定程度上降低了臭氧的产率，但是因结构的原因可以固定的碳纤维或富勒烯纤维的数量极其有限，如果在每一根金属线或针状电极上固定太多碳纤维或富勒烯纤维，远离金属线或针的碳纤维或富勒烯纤维就不能获得足够高的负高压电场强度，这些碳纤维或富勒烯纤维就不会发射电子，也就无负氧离子产生，显然这将导致负氧离子的产率较低。由于目前的金属线或针上固定的炭纤维或富勒烯纤维束的表面面积小，这就导致吸附带正电臭氧分子的能力较低，仍然存在臭氧分子浓度高的问题，仪器仍然需用臭氧分子过滤网。另外，这种金属线或针状金属电极表面包裹碳纤维或富勒烯纤维的电极无法借助强劲空气流输送产生的负氧离子到更远空间，负氧离子输送距离近。
现有的负氧离子发生机产生的负氧离子在仪器出口处极容易就被空气中的各种颗粒(如尘埃和细菌分子等)复合掉，负氧离子的输送距离近，以致于在仪器出口远处的空间所剩无几。因此，负氧离子很难传输到更远的空间为人所呼吸，并未对人们身体健康发挥多大作用，与此同时，同样不能输运到远处的臭氧分子的浓度将会愈聚愈高，对身体健康极为不利。为了降低负氧离子发生 机产生的臭氧分子浓度，普遍地都在负氧离子出口处增设过滤网。增设过滤网虽然对抑制臭氧分子深度具有一定的效果，但是在降低臭氧分子浓度的同时，也严重地降低了的负氧离子的浓度和减小了负氧离子的输送距离。
发明内容：
本发明为了弥补现有技术的不足，提供了一种产生负氧离子用的电极，它结构设计合理，提高了负氧离子的产率，大大降低了臭氧分子的产生，利用强劲的变向空气流，将产生的高浓度的负氧离子输送到非常远的空间为人所呼吸，提高了负氧离子利用率，无需过滤网，简化了本发明负氧离子发生机结构，减小了体积，解决了现有技术中存在的问题。
本发明为解决上述技术问题所采用的技术方案是：
产生负氧离子用的电极，包括一纵截面为U型的金属圈,在金属圈的U型凹槽内填充有一圈纤维束，纤维束与金属圈通过导电胶紧密胶合，所述纤维束由微米量级的碳纤维或富勒烯纤维组成。
一种使用上述产生负氧离子用的电极的负氧离子发生机，包括一风洞洞体以及罩设在风洞洞体外的外壳，风洞洞体的一端为空气入口，另一端为还原空气出口，在空气入口和还原空气出口之间的风洞洞体内设有一设置产生负氧离子用的电极的空气还原口，在空气还原口的中心处通过安装架设有产生负氧离子用的电极，在空气入口处设有入口风扇，由空气入口至空气还原口的风洞洞体内径连续平滑递减，还原空气出口的内径与空气入口的内径相同，由空气还原口至还原空气出口的风洞洞体内径连续平滑递增，负高压电源设于外壳外侧，产生负氧离子用的电极的金属圈与负高压电源通过导线相连。
在空气还原口与空气入口之间的风洞洞体内壁上沿轴向设有若干个同一旋向的来复线式螺旋沟槽。
本发明采用上述结构，结构设计合理，本发明电极采用微米量级的碳纤维或富勒烯纤维加大发射电极尖部的曲率(尖度)，增强尖部局域场强，来提高负氧离子产率，因为尖部局域场强越强愈容易产生负氧离子；纤维束成圈状排列，每根碳纤维均可在负高压下发射电子，由于本发明发射电极结构的原因，可固定的碳纤维的数量相对于以金属线或针电极为基础的一束碳纤维大大增多，增加了发射电子的能力，提高了负氧离子产率，圈状的纤维束也增大了负高压电场分布区域，负高压电场分布区域愈大，吸附捕获电离的臭氧分子和其它有害分子的能力就愈大；金属圈和圈状纤维束构成的较大的电极表面积，提高了吸附一次电离形成的臭氧分子和多次反复电离臭氧分子成为负氧离子的能力，进一步提高负氧离子产率和更有效地抑制臭氧分子产生，使负氧离子发生机无需安装过滤网，简化了结构，减小了体积；本发明电极的中部是金属圈围城的通孔，可供助通过电极圈的强劲的空气流降低发射电子的动能，从而也非常有效地抑制臭氧产生和将负氧离子输运到更远的空间；本发明负氧离子发生机利用风洞效应和弹道效应产生强劲的高速变向旋转空气流，将产生负氧离子用的电极产生的负氧离子输送到非常远的空间为人所呼吸，使负氧离子真正被人们有效利用。

如图1-3所示，产生负氧离子用的电极，包括一纵截面为U型的金属圈1,在金属圈1的U型凹槽2内填充有一圈纤维束3，纤维束3与金属圈1通过导电胶紧密胶合，所述纤维束3由微米量级的碳纤维或富勒烯纤维组成。
如图4所示，一种使用上述产生负氧离子用的电极的负氧离子发生机，包括一风洞洞体4以及罩设在风洞洞体4外的外壳5，风洞洞体4的一端为空气入口6，另一端为还原空气出口7，在空气入口6和还原空气出口7之间的风洞洞体1内设有一设置产生负氧离子用的电极的空气还原口8，在空气还原口8的中心处通过安装架设有产生负氧离子用的电极，在空气入口6处设有入口风扇9，由空气入口6至空气还原口8的风洞洞体1内径连续平滑递减，还原空气出口7的内径与空气入口6的内径相同，由空气还原口8至还原空气出口7的风洞洞体4内径连续平滑递增，负高压电源10设于外壳5外侧，产生负氧离子用的电极的金属圈1与负高压电源10通过导线相连。
使用本发明负氧离子发生机时，启动入口风扇9，产生负氧离子用的电极通电，利用内径变化的风洞洞体4能改变气流方向和加速气流流速的特性，即利用风洞效应，在风洞洞体4内产生强劲的变向空气流，将产生负氧离子用的电极产生的负氧离子输送到非常远的空间为人所呼吸。产生负氧离子用的电极通过基座可拆卸地安装在安装架上，这样在产生负氧离子用的电极损坏后，可将产生负氧离子用的电极连同基座一同更换。
在空气还原口8与空气入口6之间的风洞洞体4内壁上沿轴向设有若干个 同一旋向的来复线式螺旋沟槽11。通过在内径按照一定规律变化的风洞洞体4内设置来复线式螺旋沟槽11，将风洞效应和弹道相应结合一起，在风洞洞体4内产生强劲的高速变向旋转空气流，与只利用风洞效应相比，可将产生的负氧离子输送到更远的空间为人所呼吸。
上述具体实施方式不能作为对本发明保护范围的限制，对于本技术领域的技术人员来说，对本发明实施方式所做出的任何替代改进或变换均落在本发明的保护范围内。
本发明未详述之处，均为本技术领域技术人员的公知技术。
