Description
本发明所属技术领域
本发明总的涉及一种可调节室内空气的设备,该设备包括将通常附带着臭氧(O3)的电离空气输出的所谓电动设备,具体地说所涉及的设备具有增强的杀灭室内环境中包括芽孢、细菌及病毒在内的微生物的能力。
本发明背景技术
授予Taylor等人的美国专利No.6,163,098及授予Lee的美国专利No.4,789,801描述了利用所谓电动技术来产生电离空气流的各种设备。在一些应用中,该电动设备可小到能用手提,在另一些应用中,电动设备又可大到能调节房间内的空气。总的来说,电动技术利用强电场来电离空气分子,该过程产生作为副产物的臭氧(O3)。作为高电压电弧的副产物的臭氧通常是产生出的不稳定氧分子。在安全浓度下,臭氧是人们所需要的有用物质。但是仅仅是臭氧本身对于杀灭该设备周围环境中的诸如芽孢、细菌和病毒这样的微生物来说可能不是很有效。
图1描述了一个普通的产生臭氧的电动设备10。设备10包括壳体20,该壳体通常具有至少一个空气输入口30和至少一个空气输出口40。在壳体20内,布置了一个电极装置或系统50,其包括一个具有至少一个电极70的第一电极组(electrode array)60和具有至少一个电极90的第二电极组80。系统10还包括一个联接在第一和第二电极组之间的高电压发生器100。电极70和电极90可以具有多种形状。例如,电极70可以是细电线,而电极90可以是稍粗一些的线、棒或其他形状。电极70可以是尖端电极或针状电极,而电极90可以是包括环形在内的曲线形,也可以包括一个导电板,板上有弯曲或环形开口。电极90通常相对于电极70对称布置。例如,如果第一电极组60有三个电极70,则第二电极组80可以有两个电极90,其中电极90与最近的电极70等距并交错布置。在针状和环形结构中,电极90最好与电极70同心。
在各种结构中,所有这些电极都是导电材料,例如金属。电极90的半径最好比电极70的大,从而当发生器100施加高电压(一般几千伏)时,就在电极90处或在其附近产生一个大的电场。结果在设备10内产生了臭氧和电离的空气粒子,并且产生了由第一电极组60向第二电极组80的方向流动的电动空气流(electro-kinetic flow of air)。图1中,用“入”表示的大箭头代表进入输入口30的外界空气。多个小”x”代表存在于该流入的外界空气中的颗粒物质。该空气沿大箭头的方向运动,用”出”表示的输出空气流经过开口40流出设备10。象设备10这样的电动设备的优点在于不用风扇或其他产生气流的运动部件就可产生空气流。
外界空气中的颗粒物质x最好能被静电吸引到第二电极组80,从而从设备10输出的空气输出流(“出”)不仅包含臭氧和电离空气,而且比外界空气更干净。在这种设备中,需要不时地清洁第二电极组的电极80以将颗粒物质及其他碎屑从电极90表面除去。因此,图1的设备10可以起到类似于风扇的作用,可产生一输出空气流,而不需运动部件。在理想情况下,调节空气输出流(“出”),除去空气流中的颗粒物质,使输出流含有安全量的臭氧及一些离子。
但是含有离子和臭氧的空气输出流不能消灭或减少微生物,如芽孢、细菌、真菌、病毒等等,以下统称为“微生物”。用所谓的杀菌灯来设法消灭这些微生物是本领域技术人员所熟知的。这种灯发出波长约为254nm的紫外线辐射。例如,利用机械风扇、高效微粒空气过滤器(HEPA filter)及杀菌灯来调节空气的设备已在商业上由诸如Austin Air,C.A.R.E.2000,Amaircare以及其他公司所销售。通常,这些设备有些笨重,并具有类似于小档案柜的尺寸和体积。这种设备中,必须注意确保杀菌灯发出的紫外线辐射不会被附近的人看到以防止眼损伤。尽管这种风扇驱动设备可以减少或消灭微生物,但该设备体积庞大,并且运行时肯定不会安静。
人们所需的调节室内空气的设备是可相对安静地运行以去除空气中的颗粒物质,最好能输出安全量的臭氧,并且还可杀灭或减少诸如芽孢、真菌、细菌、病毒等等微生物的设备。
本发明提供了这样的设备。
本发明概述
第一方面,本发明提供一种电动电离设备,它具有一个挡板机构和一个封装在该设备内的杀菌灯,从而该挡板机构可防止灯发出的紫外线辐射被人看见。在一种结构中,该杀菌灯被竖直设置在近似于管状的壳体内,第一和第二电极组中的一组轴向布置在灯的一端。在另一可选的实施例中,第一和第二电极组轴向布置在灯的两端。在各种实施例中,壳体两端的进口和出口加速电动运动空气的流动,而不允许看见该灯发出的辐射。
优选的电极组结构包括针—环状电极和细长针—环状电极,电极包括由一弧状或园环状锥形导电材料形成的针状电极,以及针状电极由作为一个单独部件的电极组对称布置。一个电极组中的电极最好是彼此相对地对称布置,并可以在空气流动路径中。该杀菌灯消灭空气流中细菌、病毒、芽孢等等的功效与该空气流经受该灯的辐射的时间长度成正比。因此本发明的优选实施例将杀菌灯的纵轴设置成与该电动设备的长轴相平行。
如果需要,可以设置含水材料,如Porex,以增加调节后的空气流出流中的湿度。在一个实施例中,提供了一种个人型便携设备,其包括电动产生的空气流,该气流在输出端含有离子和臭氧,输出空气流中含有少量颗粒物质,并且作为该设备内的杀菌型灯产生的紫外线辐射的结果,该气流含有少量的微生物或几乎不含微生物。在另一可选的实施例中,该电动元件可以用由电池驱动的小风扇代替,以制得一个输出基本不含微生物的空气的个人设备。还可设置一Porex型元件,以使用户增大输出空气流的湿度。
本发明的其他特征和优点可从下面的描述中看出,在下面的描述中,结合附图,对优选实施例作了详细的描述。

图4B描述了挂在使用者脖子上的本发明图4A的设备。
优选实施例的详细描述
图2A描述了设备200的第一实施例,该设备对周围空气的进行电动调节,并提高了用于减少或消灭包括细菌、芽孢和病毒在内的微生物的能力。现在将对此进行描述,设备200吸入可能包含这类微生物以及颗粒物质(表示为x)的环境空气(“入”)。此外,不必使用运动部件,设备10即可输出调节过的空气(“出”),该空气至少除去了一些颗粒物质,并含有离子和安全量的臭氧,并且不含有上述微生物。
设备200包括壳体210,该壳体包括一个基座部分220、一个主体部分230以及一个兼作光障板的上部240。壳体210包括至少一个环境空气的进口通道250以及至少一个调节后的空气的出口通道260。显然,在此处的应用中,入口通道250相对于出口通道260来说是“上游”,或者说出口通道260在入口通道250的“下游”。“上游”和“下游”描述了空气进入、通过、流出设备200的总的流动,这用中空的大箭头表示。
壳体210的一个作用是防止附近的人(表示为270)看到布置在该壳体内的最好是紫外线灯290产生的紫外线(UV)辐射或放射280。紫外线灯290是所谓的UV-C灯,其最好能发出波长约为254nm的射线,该波长对于减少或消灭暴露于其中的细菌、芽孢和病毒是有效的。灯290可在市场上买到,例如Phillips的型号为TUO 25W/G25 T8的直径约25mm、长度约43cm的25W的管形灯。另一合适的灯是Phillips TUO 8WG8 T6,一个直径约15mm、长度约29cm的8W的灯。也可改用其他放射所需波长的灯。
辐射280作用于微生物的功效取决于该生物体经受辐射的时间长度。因此在优选实施例中,灯290以这样的方式布置在壳体210内,即该灯的纵轴与壳体内从上游至下游的气流平行。
在图2A的结构中,灯210被布置成与设备200内的最好是电动产生的气流相平行,但不与其共轴。电动气流用下述方式产生。电极装置310包括一个第一电极组320A和一个第二电极组330A。在图2A的实施例中,组320A包括一个单个针状导电电极,该电极最好终止于一个尖端。在图2A中,组330A包括一环状电极,其可由一导电圆筒制成。最好是,该电极面向电极320A的边缘基本上是圆的,从而这些边缘的有效半径R2比电极320A的有效半径R1要大得多。R2∶R1之比至少应是10,最好是15或更大。
将一个高电压脉冲发生器340联接在第一电极组320A的电极与第二电极组330A的电极之间。发生器340A接受低输入电压,例如,115VAC(交流电压)至230 VAC(交流电压)或者在一些实施例中由电池提供的6VDC(直流电压)至12VDC(直流电压),并产生重复频率约为20kHz(千赫兹)的至少10千伏峰—峰值的高电压脉冲。该输出脉冲串最好具有约10%的工作循环,特别是在电池驱动的实施例中,不过其也可具有包括100%工作循环的其他方式的工作循环。高电压脉冲发生器340可以通过许多途径实现,它通常包括一个运行频率约为20kHz的低压振荡器,该振荡器向一个电子开关输出低电压脉冲,如向一个半导体闸流管输出低电压脉冲。该半导体闸流管或其他开关将该低电压脉冲耦合到一个升压变压器的输入绕组,该升压变压器的次级绕组联接至输出高电压脉冲的高电压乘法器电路。包含高电压脉冲发生器340的各种电路和元件可被制作在一个印刷电路板上,该印刷电路板安装在壳体210内,例如安装在基座部分220内。
如图2A所示,设备200可包括一个附加电路350,例如一个用来给灯(或多个灯)290提供合适工作电压的电压调节器,并包括一个使设备200运行一定时间量的电路,等等。
在图2A的实施例中,发生器340的正输出端与第二电极组330A联接,其负输出端与第一电极组320A联接。这种耦合极性(coupling polarity)已被证实工作得很好,这包括可将不希望有的可听得见的电极振动或交流声减到最小。然而也可改用相反的极性,例如,发生器340的负端口与电极(组)330A相联接,其正端口与电极320A(组)相联接。如上所述,电极(组)320A的几何形状是这样的,即至少存在一个相对窄的或尖的尖端终点(point terminus)。这样作的一个结果是,当高电压脉冲发生器340发出的电压或脉冲通过第一和第二电极组耦合时,人们相信在第一组电极(组)320A周围产生了象等离子体一样的电场。该电场电离第一和第二电极组之间的环境空气,并形成了向着下游方向,即朝着第二组电极(组)330A移动的“出”气流。不用说,周围空气的“入”流可通过一个或多个孔250流入,电动产生的空气流沿着流经电极(组)330A的方向并至少部分通过该电极(组),并且该空气流经受紫外线辐射280,并作为”出”通过一个或多个出口孔260流出设备200。在该过程中,空气流中夹带的颗粒物质(表示为x)可被静电吸附在电极(组)330A的表面,如图2A中所示。
应当相信,臭氧和离子通过第一组电极(组)320A同时产生,其主要与联接到第一电极组的发生器340的电位有关。通过提高或降低第一电极组的电位,产生的臭氧就会增加或降低。当将具有相反极性的电位耦合到第二组电极(组)330A时,也就大大地加速了第一电极组处所产生的离子的运动,形成了如图中“出”表示的空气流。当离子朝着第二电极组移动时,就可相信它们向着第二电极组的方向推动或移动空气分子。通过降低与第一电极组电位相对的第二电极组电位,该运动的相对速度可以加大。
例如,如果+10千伏电压施加到第一组电极(组)上,而没有电位施加到第二组电极(组)上,则在第一电极组附近将形成大量的离子(其净电荷为正)。并且,该比较高的10千伏电位将产生局部浓度很大的臭氧。通过将一个相对的负电位耦合到第二组电极(组)上,由于运动离子的动量守恒,由该释放出的净离子来推动的气团的移动速度增加了。这种空气移动稀释了第一组电极附近的臭氧浓度,使臭氧浓度保持在允许浓度。
另一方面,如果想要保持同样有效的输出流(“出”)速度,并产生较少的臭氧,则该示例性的10千伏电位可以分配给两个电极组。例如,发生器340可提供+4千伏(或其他份额)给第一组电极(组),提供-6千伏(或其他份额)给第二组电极(组)。不用说,在该例中,+4千伏和-6千伏是相对于地线测得的。可以理解,人们希望本发明能输出安全量的臭氧。因此,该高电压最好被分成约+4千伏施加给第一组电极(组)和约-6千伏施加给第二组电极组。
应当注意,输出流(“出”)最好包括安全量的O3,以便消灭或至少大量改变该输出流中的细菌、芽孢和其他生物(或准生物)物质。在初步试验中可看出,将该空气流经受紫外线辐射280可以设法减少”出”流中的O3的浓度。可能是紫外线辐射加速了组成臭氧的氧原子的分解,但是申请人并未详尽地研究这个现象。可以理解,通过使用例如紫外线灯290降低O3的浓度,可允许更高速度的“出”流,而不会使O3浓度增加到不合要求的高浓度。
在图2A的实施例中,设备200具有高约24”、横截面或直径约6”的圆筒形壳体。尽管也可使用其他结构,但输入和输出孔250、260最好是每个都被形成为具有约0.5”开口高度的环形开口。壳体最好由重量轻的如ABS塑料的便宜材料制成。上部壳体元件240的下表面被形成为具有不光滑的表面光洁度或不反光的表面光洁度或颜色,以使使用者270看见由灯290发出的反射后的辐射280的可能降到最小。如图2A所建议的,壳体部分240最好具有弯曲的形状,以将”出”气流从竖直方向引导到含有水平分量的方向。
环状电极(组)330A最好具有约2”至4”的横截面或直径以及约4”至6”的长度(从上游到下游)。该电极(组)可以由铝、不锈钢等的金属圆筒或管形成。该尖端电极(组)320A最好由象钨这样的耐久导体制成,最好能承受住电离作用。电极320A的尖端部分的长度最好是至少0.5”,电极(组)320A的尖端末梢与电极(组)330A上形成的最好是弯曲的或圆形开口之间的间隔距离为约1”。当电极(组)320A相对于电极(组)330A基本上同轴对称地布置时,可得到特别好的电动输送作用。因此,在图2A中,电极(组)320A和331A的纵轴基本上同轴。
本发明的运行参数最好在生产时即被设定,并且用户不需调节。例如,增加部件340所产生的高电压脉冲的输出电压峰-峰值和/或工作循环即可增加空气流率、离子含量及臭氧含量。在优选实施例中,输出流率至少约为200英尺/分钟,离子含量约为2,000,000/cc(立方厘米),臭氧含量约为40ppb(十亿分之四十)(高于周围空气)至2,000ppb(十亿分之两千)(高于周围空气)。正如此处所描述的那样,将第二电极曲率半径/第一电极曲率半径R2/R1之比减小到约20∶1以下,将会降低流率,这将减小耦合到第一和第二电极组之间的高电压脉冲的电压峰—峰值和/或工作循环。
在设备200内,电动产生的气流在足够长的时间内受到灯290的充分辐射,即使没有消灭所进入的外界空气中的微生物的话,也可以大量减少所进入的外界空气中的微生物。因此,输出空气(“出”)经过了调节,颗粒物质就会在静电作用下沉积到电极(组)330A的表面上,并从气流中除去,诸如芽孢、真菌、细菌和病毒之类的微生物被完全地除去或基本上被除去。输出空气中存在一些有益的离子,以及安全量的O3。需要不时地清洁电极(组)330A以将沉积的颗粒物质x从该电极表面除去。
为了描述方便,在图2B的实施例中,省略了从灯290至电路350的电导线,这里的灯290基本上与电极装置310及气流同轴线布置。不用说,同轴安装灯的优点在于基本上使所放射出的所有紫外线280都对气流起作用,而在图2A的实施例中,有些射线在它作用于该气流的各个部分之前必须被壳体部分230的内壁面反射。如果需要,可以使用多个灯,包括至少一个离轴(off-axis)安装的灯(例如图2A)和一个同轴安装的灯(例如图2B)。
在图2B中还值得注意的是,电极(组)330A’面向上游(例如,向着电极(组)320A)的边缘是封闭的或圆形的。封闭(chambering)是电极(组)330A的优选实施方式,从面向电极(组)320A的电极区域开始,然后向着相反方向即下游方向继续,这样就得到了一个平滑连续的第二电极组电极表面。
在图2C的结构中,电极(组)320A使用一部分碳或其他材料320A’来实现,并如图所示,在结尾处形成多根单独的丝。各个丝充当单独的尖端或针状电极。在图2C所示的实施例中,各个丝相对于环状电极330A或330A’来讲基本上是同轴布置。
在图2D描述的结构中,环状电极(组)被设置成一个相当长的圆筒状元件330A”,其在上游方向具有光滑的向外扩张的边缘。在这种结构中,从一端安装灯290非常方便。为了描述方便,在图中省略了将灯290联接至其电源的电导线。在壳体210内还包括备用叶片360,以便用来降低气流的速度。这些叶片可使运动空气进行涡旋状旋转,降低流率,这增加了有效停留时间,在该停留时间内,灯290发出的紫外线辐射280作用于该气流。不用说,叶片360也可以设置在其他已经描述过的或将要描述的结构中。在图2D中,电极(组)330A”的直径是4”左右,长度是12”左右,不过也可以使用其他尺寸。尽管图2D中描述的电极(组)330A”与高电压脉冲发生器340正端口联接,不用说,联接到第一组和第二组电极上的脉冲的极性实际上可以与图中所示的相反。
图2E描述了第一和第二组电极的级联形式(cascade configuration),实验证明其可减小设备200发出的可听得见的嘶嘶的噪音。在这种结构中,一对第一组电极320A、320B与高电压发生器340的一个端口顺序电联接,一对第二组电极330A’、330B’与高电压发生器340的另一个端口顺序电联接。一对电极中的每个电极最好是基本上相对于彼此对称或同轴布置。因此,电极320A相对于电极330A’对称布置,并且在该情况下,还同轴布置;电极320B相对于电极330B’对称布置,并且在该情况下,也同轴布置。描述不同形状的环状电极330A’和330B’是为了说明存在着相对自由的设计选择。然而在各种结构中,最好满足前面所述的R2/R1>10的比例。
图2E所示的是一可选的环状(或其他结构的)水份保持材料390,与至少一个出口孔260相邻布置,以对空气输出流提供最小的阻力。在该优选实施例中,水份保持部件390是中空的环状圆筒,约0.125”厚的PorexTMUHMW X-4901材料,其可用水、用香水、或可用药物(例如,治疗哮喘的药物)润湿。这种材料具有聚乙烯基,表现出毛细作用,并能吸收和保持大量的水份。用户可以定期湿润该材料,如果用户希望如此,则该空气输出流(”出”)不仅可含有有益量的臭氧、某些离子、少量颗粒物质、极少或没有微生物,而且还可增加湿度。这种材料390可以被设置在此处描述的本发明的其它结构中。
图2F描述了本发明的一种结构,其中壳体210在上部区域设置进气口或孔250,在下部区域设置出气口或孔260。在这种结构中,如图所示,杀菌紫外线灯290布置在该壳体的下部区域。尽管图2F描述了一个具体的针状和环状电极的结构,不用说其他电极结构和/或附加电极结构也可被用来建立所需的电动气流,并析出所流入的外界空气中的颗粒物质x,输出离子以及输出安全量的臭氧。需指出的是,可有选择地设置一环状或其他结构的水份保持材料260。
现在转到图3A和3B,图中示出一个电极装置310的紧凑结构,该结构所产生的空气流的总体积与更大结构的电极装置所产生的空气流总体积相同。该装置特别耐用,可以从设备壳体中取出并在普通家用洗碗水中洗涤以洗掉累积的颗粒物质及其他物质。图3B描述了由于发生器340产生的高电压施加到该电极装置而产生的场力线(force field lines)。
在图3A的结构中,多个同心布置的第一组电极320A被布置在多个同心布置的第二组电极330A的上游。从图3B可以最清楚地看出,末端(面向下游的端部或图中的右端)最好是锥形的、或者尖端、或者是尖的。为了说明设计的灵活性,图中显示的第一组电极320A的锥形末端点彼此基本平齐,不过它们也可以交错排列。相反,图中显示的第二组电极330A的朝着上游的最好是弧形末端交错排列,不过它们也可彼此基本平齐。
第一组电极320A可通过对耐用金属(durable metal)进行机加工或用其他方式加工而形成,使这些电极彼此电联接,并与高电压脉冲发生器340的一个输出端口,例如与正端口相联。同样,第二组电极330A可由耐用金属形成,使这些电极彼此电联接,并与高电压脉冲发生器340的另一输出端口相连。该结构与其他电极结构一样,不用说,高电压脉冲发生器340的一个输出端口或端子实际上可以具有与周围空气相同的电位。
图3A所示的结构的外部直径约为6”至8”、长度约为4”至10”、部件320A或部件330A的两相邻同心园环之间的间距为0.25”至0.5”。不过也可使用其他尺寸。如果需要,图3A的结构可以进行略微改进,电极320A和330A使用偏置螺旋形结构。螺旋形结构可简化加工过程,并可简化电极间的电连接。
如图3B所示,流入空气(“入”)中的颗粒物质(用x表示)有可能因静电而附着在下游第二组电极330A的表面上。而该输出气流(”出”)则基本上不含有这些颗粒物质,并含有离子及安全量的O3。另外,杀菌型紫外线灯290(在图3A、3B中未示出)的存在将确保存在于流入空气中的微生物在该空气输出流(”出”)中被充分地除去。可以理解,如果需要,可以设置一个环形或多个环形(或其他结构的)水份保持材料390,并最好邻近电极装置310的下游部分而设置。
图4A是电池驱动的个人设备400的分解透视图,图中壳体410包括一个具有入口通道250的上部壳体部件420和一个下部壳体部件430,并可容纳:在其它部件之间的给设备400供电的电池B1,提供B1出入口的电池舱口盖440。一个ON/OFF开关S1可将B1联接至壳体410内的高电压发生器及电路340、350。壳体410还包括前部壳体部分450,并提供出口通道260。在该优选实施例中,至少一部分出口区的内部区域包括如上所述的泡沫状液体保持材料260,该材料湿润时可增加输出空气流”出”的湿度。
在所示的实施例中,气流最好由包括两对电极组的电极装置310电动产生。尽管它不产生臭氧和/或离子,也可替代地或附加地设置一个直流驱动小风扇500来产生气流。在图4A中,针状和环状电极320A和330B’。第一组电极320A可以是如图2A至2F中所示的那样,第二组电极330B’最好是喇叭形的,如图2E所示。每个针状或尖端电极320A在上游,并最好与环状电极330B’同轴。一个环状水份保持材料390被布置在壳体450内,以便使其受到流经相邻电极330B’的光滑连续内表面的气流。
设备400还包括一个如前面所描述的杀菌型紫外线灯290。灯290被设置在壳体410内以使气流(不管是电动产生的还是风扇500产生的)经受该灯发出的紫外线辐射。
图4B显示出的是用绳510将设备400挂在使用者的脖子上。电池驱动设备400有助于在诸如汽车、飞机等这样拥挤的地方使用,这些地方的周围空气不纯净。在设备400内设置灯290可以有助于将输出气流(”出”)中芽孢、细菌、真菌、病毒消灭掉。该电动产生的气流有助于设备400的静默运行,并用来输出至少清除了部分颗粒物质的、并可含有离子和/或臭氧的输出空气。另外,设置可湿润的材料390可允许设备400的佩带者或使用者增加输出空气流的水份、和/或添加有香水的液体和/或药物以进一步提高输出气流的自然性和品质。尽管在图4B中设备400被显示为佩带在使用者的身体附近,但设备400也可以被放置在汽车的仪表板上,如果需要,可由汽车电池供电。
在不背离本发明权利要求书所限定的本发明的主题和精神的前提下,可对此处公开的实施例作出改进和变形。
