  • the present invention relates to a microbubble generating device, in particular to a microbubble spray head and a washing equipment with the microbubble spray head.
  • Micro-bubble usually refers to tiny bubbles with a diameter below fifty microns ( ⁇ m) when the bubbles occur. Micro-bubbles can also be called micro-/nano-bubble, micro-bubble or nano-bubble according to their diameter range. Because of its small buoyancy in the liquid, the microbubbles stay in the liquid for a long time. Moreover, the microbubbles will shrink in the liquid until they finally break, generating smaller nanobubbles. In this process, the bubble's rising speed becomes slow because it becomes smaller, resulting in high melting efficiency. When the microbubbles are broken, high pressure and high temperature heat are generated locally, which can destroy foreign objects such as organic matter floating in the liquid or attached to the object.

技术领域
本发明涉及微气泡产生装置，具体地涉及微气泡喷头及具有该微气泡喷头的洗涤设备。
背景技术
微气泡(micro-bubble)通常是指气泡发生时直径在五十微米(μm)以下的微小气泡。微气泡根据其直径范围也可以称为微纳气泡(micro-/nano-bubble)、微米气泡或纳米气泡(nano-bubble)。微气泡由于其在液体中的浮力小，因此在液体中滞留的时间比较长。而且，微气泡在液体中会发生收缩直到最后破碎，生成更小的纳米气泡。在这个过程中，气泡因为变小所以其上升速度变得缓慢，导致融化效率高。微气泡在破碎的时候局部会产生高压和高温的热，由此能够破坏漂浮在液体中或附着在物体上的有机物等异物。另外，微气泡的收缩过程还伴随负电荷的增加，负电荷的高峰状态通常是在微气泡的直径处于1-30微米的时候，因此容易吸附漂浮在液体中的带正电荷的异物。结果就是异物在其由于微气泡的破碎而被破坏之后会被微气泡吸附，然后慢慢浮到液体表面。这些特性使得微气泡具备很强的清洗和净化能力。目前，微气泡已经被广泛应用于洗衣机等洗涤设备中。
为了制造微气泡，不同结构的微气泡产生装置已经被开发出来。例如，中国发明专利申请(CN107321204A)公开了一种微气泡产生器。该微气泡产生器包括两端为开口状的外壳，外壳的第一端连接有进水管，在外壳内沿着水流方向依次设置有涡柱、涡柱壳、气液混合管以及定位在外壳的第二端的孔网。气液混合管从头部到尾部依次形成有连通的容置腔、气流部、加速部和流通部。涡柱壳及位于其内的涡柱定位在容置腔内；气流部的管壁上设有进气口；气流部的内壁朝向容置腔的方向凸出，形成呈漏斗状的凸出部，在漏斗状凸出部的大口端与锥形的涡柱壳之间形成供由进气口进入的空气进入气流部的缝隙；加速部的内径朝向尾部方向逐渐增大。水流流经涡柱在涡柱壳内部形成高速旋转水流，高速旋转水流从涡柱壳的出口流出后进入凸出部围成的漏斗状空间内，在水流周围形成的负压将空气从进气口吸入并与水流混合后进入加速部，由于涡柱壳的锥形面以及加速部的内径朝向尾部方向逐渐增大而形成压差，使混合大量空气的水流(形成气泡水)加速流动，气泡水经由流通部流向孔网，气泡水被孔网中的细孔切割并混合而产生含有大量微气泡的微气泡水。
中国发明专利申请(CN107583480A)也公开了一种微气泡产生器。该微气泡产生器包括两端为开口状的外壳，外壳的第一端连接有进水管，在外壳内沿着水流方向依次设置有增压管、气泡产生管以及定位在外壳的第二端的孔网。气泡产生管从第一端到第二端依次形成有容置腔、气液混合部、扩张引导部。在容置腔内接纳增压管，增压管具有面向容置 腔的锥形端；在气液混合部内形成有沿着第一端到第二端的方向尺寸逐渐减小的锥形的气液混合空间；扩张引导部内形成有沿着第一端到第二端的方向尺寸增大的扩张引导空间。气泡产生管的管壁上设有进气通道，气液混合部的内壁与增压管的外壁之间形成间隙以便与气泡产生管的管壁上的进气通道连通，增压管的出水口置于气液混合部的进水口内。水流流经增压管被增压形成高速水流，高速水流从增压管的出水口流出后进入气液混合腔并且在气液混合腔内形成负压，该负压将大量空气通过进气通道吸入水流中并且使空气与水混合形成气泡水，气泡水从扩张引导部流向孔网，气泡水被孔网的细孔混合和切割形成微气泡水。
上述两种微气泡产生器均具有至少五种独立的部件：外壳，进水管，涡柱和涡壳或增压管，气液混合管或气泡产生管，以及孔网。这些部件都需要设计特定的配合或连接结构，以便所有部件能够组装在一起并且保证组装好的微气泡产生器能够可靠地工作。因此，这样的微气泡产生器的部件和结构都比较复杂，并且制造成本也很高。
相应地，本领域需要一种新的技术方案来解决上述问题。
发明内容
在第一实施方式中，为了解决现有技术中的上述问题，即为了解决现有微气泡产生器结构复杂、制造成本高的技术问题，本发明提供了一种微气泡喷头，所述微气泡喷头包括一体式喷管和固定在所述一体式喷管的出口端上的微气泡起泡器，在所述一体式喷管内设有节流通道部，在所述节流通道部内沿着水流方向形成有相互平行的多个等截面节流通道，使得多股水流能够在所述多个等截面节流通道中形成并且从所述多个等截面节流通道的出口膨胀地喷出以在所述出口附近产生负压；在所述一体式喷管上还设有进气通道，所述进气通道定位成靠近所述出口，使得空气在所述负压下能够从所述进气通道吸入并且与所述多股水流混合产生气泡水，所述气泡水通过所述微气泡起泡器形成微气泡水。

第一实施方式
为了解决现有微气泡产生器的结构复杂、制造成本高的问题，本发明提供了一种微气泡喷头52。该微气泡喷头52包括一体式喷管521和固定在一体式喷管521的出口端212上的微气泡起泡器522(参见图3-8)。在一体式喷管521内设有节流通道部217。在节流通道部217内沿着水流方向C形成有相互平行的多个等截面节流通道218，使得多股水流能够在多个等截面节流通道218中形成并且从多个等截面节流通道218的出口218b膨胀地喷出以在出口218b附近产生负压。在一体式喷管521上还设有进气通道，进气通道定位成靠近出口218b，使得空气在负压下能够从进气通道吸入并且与多股水流混合产生气泡水，气泡水通过微气泡起泡器522形成微气泡水。因此，相比于现有技术的微气泡发生器，本发明微气泡喷头的部件数量和结构都被大大简化，并且微气泡喷头的制造成本也大幅降低，同时微气泡喷头仍保持良好的产生微气泡的性能。
在本文中提及的“等截面”是指每个节流通道的横向于水流方向C的横截面保持不变。
本发明微气泡喷头52可以应用在洗涤领域，杀菌领域，或者其它需要微气泡的领域。例如，本发明微气泡喷头52既能够应用到洗涤设备中，也能够结合到卫浴水龙头或花洒等装置中。
因此，本发明还提供一种洗涤设备，该洗涤设备包括本发明的微气泡喷头52。该微气泡喷头52设置成在该洗涤设备内产生微气泡水。通过微气泡喷头在洗涤设备内产生 含有大量微气泡的微气泡水，不仅能够提高洗涤设备的洗净能力，而且能够减少洗涤剂的用量并降低洗涤剂在例如衣物中的残留量，从而不仅有利于用户的健康，而且还能改善用户的体验。
参照图1，图1是本发明具有微气泡喷头的洗涤设备的一种实施例的结构示意图。在该实施例中，洗涤设备为一种波轮洗衣机1。替代地，在其它实施例中，洗涤设备可以是滚筒洗衣机或烘干一体机等。
如图1所示，波轮洗衣机1(以下简称洗衣机)包括箱体11。在箱体11的底部设有地脚14。箱体11的上部设置有盘座12，盘座12枢转连接有上盖13。在箱体11内设置有作为盛水桶的外桶21。在外桶21内设置有内桶31，内桶31的底部设置有波轮32，外桶21的下部固定有电机34，电机34通过传动轴33与波轮32驱动连接，在内桶31的侧壁上设有脱水孔311，通过这些脱水孔311洗涤水或来自衣物上的水能够从内桶31流出并进入外桶21。排水阀41设置在排水管42上，排水管42的上游端与外桶21的底部连通。该波轮洗衣机1还包括进水阀51和与进水阀51连通的微气泡喷头52，微气泡喷头52被安装在外桶21的顶部上。水经由进水阀51进入微气泡喷头52以产生包含大量微气泡的微气泡水，微气泡喷头52将微气泡水先喷入洗涤剂盒以与洗涤剂混合，然后经由洗涤剂盒进入内桶31，用于衣物清洗。水中的微气泡在破碎过程中对洗涤剂产生撞击，并且微气泡通过携带的负电荷也能够吸附洗涤剂，因此微气泡能够增加洗涤剂与水的混合程度，从而降低洗涤剂的用量并减少洗涤剂在衣物上的残留量。另外，微气泡在内桶31内也会撞击衣物上的污渍，并且会吸附产生污渍的异物。因此，微气泡还增强了洗衣机的去污性能。可选地，微气泡喷头还可以直接将携带大量微气泡的微气泡水喷入洗衣机的外桶21或内桶31，以进一步降低洗涤剂的用量并增强洗衣机的清洁能力。
参照图2，图2是本发明具有微气泡喷头的洗涤设备的另一种实施例的结构示意图。在该实施例中，洗涤设备为一种滚筒洗衣机9。
如图2所示，滚筒洗衣机9包括外壳91和位于外壳底部的地脚98。在外壳91的顶部设有上台面板94。外壳91的前侧(面对用户的操作侧)上设有允许用户向滚筒洗衣机内装填衣物等的门体97，而门体97上还设有能够看到洗衣机内部的观察窗96。在观察窗96与外壳91之间还设置密封窗垫961，并且该密封窗垫961固定在外壳91上。滚筒洗衣机9的控制面板95布置在外壳91的前侧的上部，以便于用户的操作。在外壳91的内部则布置有外筒92和内筒93。内筒93定位在外筒92的内部。内筒93通过传动轴932和轴承933连接到电机931(例如直驱电机)。在外壳91的后侧的上部上设有进水阀51，该进水阀51通过水管连接到微气泡喷头52。如图2所示，微气泡喷头52定位靠近外壳91的前侧上部，并且位于控制面板95的下方。类似于上述实施例，水经由进水阀51通过水管进入微气泡喷头52以产生包含大量微气泡的微气泡水，微气泡喷头52将微气泡水先喷入洗涤剂盒以与洗涤剂混合，然后经由洗涤剂盒进入内筒93，用于衣物清洗。可选地，微气泡喷头52还可以直接将携带大量微气泡的微气泡水喷入洗衣机的外筒92或内筒93，以进一步降低洗涤剂的用量并增强洗衣机的清洁能力
参照图3-图6，图3-图6是本发明微气泡喷头的实施例的示意图，其中，图3是本发明微气泡喷头的实施例的立体示意图，图4是图3所示的本发明微气泡喷头的实施例的俯视图，图5是图3所示的本发明微气泡喷头的实施例的左视图，以及图6是图3所示的本发明微气泡喷头的实施例的正视图。如图3-6所示，在一种或多种实施例中，本发明微气泡喷头52包括一体式喷管521。在一体式喷管521的出口端212上固定有微气泡起泡器522，微气泡起泡器522配置成能够在气泡水流过其时切割和混合气泡水而产生含有大量微气泡的微气泡水。
参照图3，在一种或多种实施例中，一体式喷管521具有进口端211和出口端212。在出口端212上固定有微气泡起泡器522，而进口端211则用于连接到外部水源。可选地，在进口端211上可设置止脱部213，例如围绕进口端211的外壁径向向外隆起的止脱筋或者进口端211的外壁向内凹进的环形沟槽结构，能够防止一体式喷管521从其所连接的提供水源的管道上脱落。
继续参照图3，在一种或多种实施例中，在一体式喷管521的外壁上设有第一固定安装部214A，第二固定安装部214B，以及定位部215，用于将微气泡喷头52定位和固定到预定位置。
参照图4-图6，第一固定安装部214A和第二固定安装部214B对称地定位在一体式喷管521的外壁上，并且位于一体式喷管521的中部。定位部215则为长条肋，从一体式喷管521的外壁径向向外突出，并且沿着一体式喷管521的纵向延伸。第一固定安装部214A和第二固定安装部214B分布在定位部215的两侧。可选地，在一体式喷管521上只设置一个固定安装部，而定位部215也可以采用其它合适的形式。
在一种或多种实施例中，第一和第二固定安装部214A，214B为螺钉孔结构，以通过螺钉将喷头52固定到目标位置。然而，固定安装部可采用任何合适的其它形式的连接结构，例如卡扣连接结构、焊接连接结构等。
图7是沿着图6的剖面线A-A截取的本发明微气泡喷头在第一实施方式中的一种实施例的剖视图。如图7所示，在一体式喷管521内，沿着水流方向C设有节流通道部217。在一种或多种实施例中，节流通道部217与一体式喷管521形成为一体，例如通过一体注塑成型。在替代地实施例中，节流通道部217独立于一体式喷管521形成，然后被插入到一体式喷管521内并且被卡在一体式喷管521中。替代地，独立形成的节流通道部217也能够被压合在一体式喷管521中。
参照图7，在节流通道部217内设有多个等截面节流通道218。在一种或多种实施例中，等截面节流通道218的数量为2-16个，这些等截面节流通道围绕一体式喷管521的中心线按照环形形式均匀地分布。替代地，等截面节流通道218的数量可以为6-9个。可选地，这些等截面节流通道也可以以环形以外的形式布置，并且可以不是均匀分布地。在一种或多种实施例中，所有等截面节流通道218的横向于水流方向C的截面都相同。替代地，这些等截面节流通道218也可以采用不同的横截面，例如靠近一体式喷管521的中心的等截面节流通道的横截面大于远离一体式喷管521的中心的等截面节流通道。
继续参照图7，每个等截面节流通道218都包括进口218a和出口218b。从一体式喷管521的进口端211流入的水流从每个等截面节流通道218的进口218a进入并且因此被分成多股水流。这多股水流在对应的等截面节流通道218内被加压，并且当这多股水流从多个等截面节流通道218的出口218b喷出时被快速地膨胀，因此在多个等截面节流通道218的出口218b附近产生负压区。
如图7所示，一体式喷管521的外壁上形成有作为进气通道的多个进气孔216。这些进气孔216围绕一体式喷管521的外壁布置成两个环形，并且这些进气孔216定位都靠近等截面节流通道218的出口218b，因此处于负压区内。在负压的作用下，大量外部空气能够从进气孔216被吸入一体式喷管521并且与从多个等截面节流通道218喷出的多股水流混合而产生气泡水。气泡水然后流向下游的微气泡起泡器522以形成微气泡水。在替代的实施例中，根据需要，可以设置更多或更少的进气孔，并且能够以其它方式排布，例如以交错方式排列。
位于一体式喷管521的出口端212上的微气泡起泡器522包括孔网221和孔网骨架222。孔网221通过孔网骨架222附接到一体式喷管521的出口端212上。
在一种或多种实施例中，孔网221具有至少一道细孔的直径达微米级。优选地，细孔的直径在0～1000微米之间；更优选地，细孔的直径在5～500微米之间。孔网221可以是塑料栅栏，金属网，高分子材料网，或者其它合适的孔网结构。塑料栅栏通常是指高分子栅栏，其由高分子材料一体注塑成型，或者先将高分子材料制成板，再在该板上通过机加工产生微孔结构而形成塑料栅栏。高分子材料网通常是指通过先将高分子材料制成丝，再用这丝编织成的具有微孔结构的网。高分子材料网可以包括尼龙网，棉纶网，涤纶网，丙纶网等。替代地，孔网221可以是能够产生微气泡的其它孔网结构，例如由两个非微米级的蜂窝状结构组成的孔网结构。当气泡水流过孔网221时，孔网221对气泡水产生混合和切割的作用，从而产生微气泡水。
参照图7，孔网骨架222呈圆筒状以便能够套在一体式喷管521的出口端212上。在一种或多种实施例中，孔网骨架222与一体式喷管的出口端212通过螺纹连接部300固定在一起。例如，在孔网骨架222的内壁上形成内螺纹，并且在出口端212的外壁上形成外螺纹，该内螺纹与外螺纹啮合在一起。在替代的实施例中，孔网骨架222可以采用其它合适的形式，例如压板的形式，并且通过其它连接方式与一体式喷管521的出口端连接，例如焊接的方式。可选地，孔网还可以直接形成在一体式喷管的出口端212上。
如图3-7所示，在一种或多种实施例中，孔网骨架222沿着其外周设有多个溢流孔223，并且这些溢流孔定位靠近孔网221。当气泡水不能及时从孔网221通过时，多余的气泡水能够从溢流孔223流出，从而能够防止多余的水回流而淹没进气孔216。因此，溢流孔223能够阻止因进气孔216被堵而使空气无法被吸入一体式喷管因此无法产生微气泡水的情形。在替代的实施例中，根据需要，可以设置更多或更少的溢流孔223。
继续参照图7，在一种或多种实施例中，在孔网骨架222与一体式喷管521的出口端212之间还设置压环225。相应地，孔网221的周边上设有连接部224。压环225将该连接部224压在孔网骨架222的端部内壁上，从而能够牢固地固定孔网221，使得孔网221在经受高压水流冲击的时候不会从一体式喷管521的出口端212上脱落。在替代的实施例中，孔网221也可以利用其它结构进行固定，例如用卡簧卡住孔网。在一种或多种实施例中，压环225上也设有多个压环孔226。在喷射水流流量不大的情况下，这些压环孔226可以用于将空气吸入并与水流混合。在喷射水流流量比较大时，允许部分水从这些压环孔226溢出，由此不仅能够帮助清洁孔网，而且还能阻止多余的水逆流通过进气通道而导致无法通过这些进气通道吸入空气。
图8是沿着图6的剖面线A-A截取的本发明微气泡喷头在第一实施方式中的另一种实施例的剖视图。如图8所示，在该实施例中，节流通道部217独立于一体式喷管521通过注塑形成。另外，在该实施例中，孔网骨架222与一体式喷管的出口端212也是通过螺纹连接部300固定在一起，并且在螺纹连接部300中形成螺纹进气通道216’，例如是形成在外螺纹与内螺纹之间的间隙。因此，在该实施例中，进气通道不仅包括位于一体式喷管521外壁上的进气孔216，还包括螺纹进气通道216’。在替代的实施例中，喷头52的进气通道也可以只包括设置在一体式喷管521的出口端与微气泡起泡器之间的进气通道。
第二实施方式
为了解决现有微气泡产生器的结构复杂、制造成本高的问题，本发明提供了一种微气泡喷头52。该微气泡喷头52包括一体式喷管521和固定在一体式喷管521的出口端212 上的微气泡起泡器522(参见图3-6和图9-10)。在一体式喷管521内设有变直径通道部217。在变直径通道部217内沿着水流方向C形成有相互平行的多个变直径通道218，每个变直径通道218沿着水流C方向依次包括直径变小锥形通道218a和直径变大锥形通道218c。可被直径变小锥形通道218a加压(同时也被加速)的水流在直径变大锥形通道218c内能够膨胀以便在变直径通道218的出口218d附近产生负压。在一体式喷管521上还设有进气通道，进气通道定位成靠近出口218d，使得空气在负压下能够从进气通道吸入并且与与来自多个变直径通道218的多股水流混合产生气泡水，该气泡水通过微气泡起泡器522形成微气泡水。因此，相比于现有技术的微气泡发生器，本发明微气泡喷头的部件数量和结构都被大大简化，并且微气泡喷头的制造成本也大幅降低，同时微气泡喷头仍保持良好的产生微气泡的性能。
在本文中提及的“变直径通道”是指每个通道的横向于水流方向C的尺寸(例如直径)有变化。本发明微气泡喷头可以应用在洗涤领域，杀菌领域，或者其它需要微气泡的领域。例如，本发明微气泡喷头既能够应用到洗涤设备中，也能够结合到卫浴水龙头或花洒等装置中。
因此，本发明还提供一种洗涤设备，该洗涤设备包括本发明的微气泡喷头52。该微气泡喷头52设置成在该洗涤设备内产生微气泡水。通过微气泡喷头在洗涤设备内产生含有大量微气泡的微气泡水，不仅能够提高洗涤设备的洗净能力，而且能够减少洗涤剂的用量并降低洗涤剂在例如衣物中的残留量，从而不仅有利于用户的健康，而且还能改善用户的体验。
参照图1，图1是本发明具有微气泡喷头的洗涤设备的一种实施例的结构示意图。在该实施例中，洗涤设备为一种波轮洗衣机1。替代地，在其它实施例中，洗涤设备可以是滚筒洗衣机或烘干一体机等。
如图1所示，波轮洗衣机1(以下简称洗衣机)包括箱体11。在箱体11的底部设有地脚14。箱体11的上部设置有盘座12，盘座12枢转连接有上盖13。在箱体11内设置有作为盛水桶的外桶21。在外桶21内设置有内桶31，内桶31的底部设置有波轮32，外桶21的下部固定有电机34，电机34通过传动轴33与波轮32驱动连接，在内桶31的侧壁上设有脱水孔311，通过这些脱水孔洗涤水或来自衣物上的水能够从内桶31流出并进入外桶21。排水阀41设置在排水管42上，排水管42的上游端与外桶21的底部连通。该洗衣机还包括进水阀51和与进水阀51连通的微气泡喷头52，微气泡喷头52被安装在外桶21的顶部上。水经由进水阀51进入微气泡喷头52以产生包含大量微气泡的微气泡水，微气泡喷头52将微气泡水先喷入洗涤剂盒以与洗涤剂混合，然后经由洗涤剂盒进入内桶31，用于衣物清洗。水中的微气泡在破碎过程中对洗涤剂产生撞击，并且微气泡通过携带的负电荷也能够吸附洗涤剂，因此微气泡能够增加洗涤剂与水的混合程度，从而降低洗涤剂的用量并减少洗涤剂在衣物上的残留量。另外，微气泡在内桶31内也会撞击衣物上的污渍，并且会吸附产生污渍的异物。因此，微气泡还增强了洗衣机的去污性能。可选地，微气泡喷头还可以直接将携带大量微气泡的微气泡水喷入洗衣机的外桶21或内桶31，以进一步降低洗涤剂的用量并增强洗衣机的清洁能力。
参照图2，图2是本发明具有微气泡喷头的洗涤设备的另一种实施例的结构示意图。在该实施例中，洗涤设备为一种滚筒洗衣机9。
如图2所示，滚筒洗衣机9包括外壳91和位于外壳底部的地脚98。在外壳91的顶部设有上台面板94。外壳91的前侧(面对用户的操作侧)上设有允许用户向滚筒洗衣机内装填衣物等的门体97，而门体97上还设有能够看到洗衣机内部的观察窗96。在观察窗96与外壳91之间还设置密封窗垫961，并且该密封窗垫961固定在外壳91上。滚筒洗衣机9的控制面板95 布置在外壳91的前侧的上部，以便于用户的操作。在外壳91的内部则布置有外筒92和内筒93。内筒93定位在外筒92的内部。内筒93通过传动轴932和轴承933连接到电机931(例如直驱电机)。在外壳91的后侧的上部上设有进水阀51，该进水阀51通过水管连接到微气泡喷头52。如图2所示，微气泡喷头52定位靠近外壳91的前侧上部，并且位于控制面板95的下方。类似于上述实施例，水经由进水阀51通过水管进入微气泡喷头52以产生包含大量微气泡的微气泡水，微气泡喷头52将微气泡水先喷入洗涤剂盒以与洗涤剂混合，然后经由洗涤剂盒进入内筒93，用于衣物清洗。可选地，微气泡喷头52还可以直接将携带大量微气泡的微气泡水喷入洗衣机的外筒92或内筒93，以进一步降低洗涤剂的用量并增强洗衣机的清洁能力
参照图3-图6，图3-图6是本发明微气泡喷头的实施例的示意图，其中，图3是本发明微气泡喷头的实施例的立体示意图，图4是图3所示的本发明微气泡喷头的实施例的俯视图，图5是图3所示的本发明微气泡喷头的实施例的左视图，以及图6是图3所示的本发明微气泡喷头的实施例的正视图。如图3-6所示，在一种或多种实施例中，本发明微气泡喷头52包括一体式喷管521。在一体式喷管521的出口端212上固定有微气泡起泡器522，微气泡起泡器522配置成能够在气泡水流过其时切割和混合气泡水而产生含有大量微气泡的微气泡水。
参照图3，在一种或多种实施例中，一体式喷管521具有进口端211和出口端212。在出口端212上固定有微气泡起泡器522，而进口端211则用于连接到外部水源。可选地，在进口端211上可设置止脱部213，例如围绕进口端211的外壁径向向外隆起的止脱筋或者进口端211的外壁向内凹进的环形沟槽结构，能够防止一体式喷管521从其所连接的提供水源的管道上脱落。
继续参照图3，在一种或多种实施例中，在一体式喷管521的外壁上设有第一固定安装部214A，第二固定安装部214B，以及定位部215，用于将微气泡喷头52定位和固定到预定位置。
参照图4-图6，第一固定安装部214A和第二固定安装部214B对称地定位在一体式喷管521的外壁上，并且位于一体式喷管521的中部。定位部215则为长条肋，从一体式喷管521的外壁径向向外突出，并且沿着一体式喷管521的纵向延伸。第一固定安装部214A和第二固定安装部214B分布在定位部215的两侧。可选地，在一体式喷管521上只设置一个固定安装部，而定位部215也可以采用其它合适的形式。
在一种或多种实施例中，第一和第二固定安装部214A，214B为螺钉孔结构，以通过螺钉将喷头52固定到目标位置。然而，固定安装部可采用任何合适的连接结构，例如卡扣连接结构、焊接连接结构等。
图9是沿着图6的剖面线A-A截取的本发明微气泡喷头在第二实施方式中的一种实施例的剖视图。如图9所示，在一体式喷管521内，沿着水流方向C设有变直径通道部217。在一种或多种实施例中，变直径通道部217与一体式喷管521形成为一体，例如通过一体注塑成型。在替代地实施例中，变直径通道部217独立于一体式喷管521形成，然后被插入到一体式喷管521内，并且被卡在一体式喷管521中。替代地，独立形成的节流通道部217也能够被压合在一体式喷管521中。
参照图9，在变直径通道部217内设有多个变直径通道218。在一种或多种实施例中，变直径通道218的数量为2-16个，这些变直径通道围绕一体式喷管521的中心线按照环形形式均匀地分布。替代地，变直径通道218的数量可以为6-9个。可选地，这些变直径通道也可以以环形以外的形式布置，并且可以不是均匀分布地。在一种或多种实施例中，所有变直径通道218的配置都相同。替代地，这些变直径通道218也可以采用不同的配置，例如在垂直 于水流方向C的同一径向位置上，靠近一体式喷管521的中心的变直径通道218的直径(因此横截面)大于远离一体式喷管521的中心的变直径通道218的的直径(因此横截面)。
继续参照图9，每个变直径通道218都包括直径变小锥形通道218a和直径变大锥形通道218c。沿着水流方向C，直径变小锥形通道218a的下游最小直径端与直径变大锥形通道218c的上游最小直径端重合，因此形成最小直径通道218b。从一体式喷管521的进口端211流入的水流先进入每个变直径通道218的直径变小锥形通道218a并且在其中被加压，然后通过最小直径通道218b后进入直径变大锥形通道218c。在直径变大锥形通道218c中，水流被快速地膨胀，因此当膨胀的水流从直径变大锥形通道218c的出口218d(也是变直径通道218的出口2)喷出后，在该出口218d附近就会产生负压区。
如图9所示，一体式喷管521的外壁上形成有作为进气通道的多个进气孔216。这些进气孔216围绕一体式喷管521的外壁布置成两个环形，并且这些进气孔216定位都靠近变直径通道218的出口218d，因此处于负压区内。在负压的作用下，大量外部空气能够从进气孔216被吸入一体式喷管521并且与从多个变直径通道218喷出的多股水流混合而产生气泡水。气泡水然后流向下游的微气泡起泡器522以形成微气泡水。在替代的实施例中，根据需要，可以设置更多或更少的进气孔，并且能够以其它方式排布，例如以交错方式排列。
位于一体式喷管521的出口端212上的微气泡起泡器522包括孔网221和孔网骨架222。孔网221通过孔网骨架222附接到一体式喷管521的出口端212上。
在一种或多种实施例中，孔网221具有至少一道细孔的直径达微米级。优选地，细孔的直径在0～1000微米之间；更优选地，细孔的直径在5～500微米之间。孔网221可以是塑料栅栏，金属网，高分子材料网，或者其它合适的孔网结构。塑料栅栏通常是指高分子栅栏，其由高分子材料一体注塑成型，或者先将高分子材料制成板，再在该板上通过机加工产生微孔结构而形成塑料栅栏。高分子材料网通常是指通过先将高分子材料制成丝，再用这丝编织成的具有微孔结构的网。高分子材料网可以包括尼龙网，棉纶网，涤纶网，丙纶网等。替代地，孔网221可以是能够产生微气泡的其它孔网结构，例如由两个非微米级的蜂窝状结构组成的孔网结构。当气泡水流过孔网221时，孔网221对气泡水产生混合和切割的作用，从而产生微气泡水。
参照图9，孔网骨架222呈圆筒状以便能够套在一体式喷管521的出口端212上。在一种或多种实施例中，孔网骨架222与一体式喷管的出口端212通过螺纹连接部300固定在一起。例如，在孔网骨架222的内壁上形成内螺纹，并且在出口端212的外壁上形成外螺纹，该内螺纹与外螺纹啮合在一起。在替代的实施例中，孔网骨架222可以采用其它合适的形式，例如压板的形式，并且通过其它连接方式与一体式喷管521的出口端连接，例如焊接的方式。可选地，孔网还可以直接形成在一体式喷管的出口端212上。
如图3-6和图9所示，在一种或多种实施例中，孔网骨架222沿着其外周设有多个溢流孔223，并且这些溢流孔定位靠近孔网221。当气泡水不能及时从孔网221通过时，多余的气泡水能够从溢流孔223流出，从而能够防止多余的水回流而淹没进气孔216。因此，溢流孔223能够阻止因进气孔216被堵而使空气无法被吸入一体式喷管因此无法产生微气泡水的情形。在替代的实施例中，根据需要，可以设置更多或更少的溢流孔223。
继续参照图9，在一种或多种实施例中，在孔网骨架222与一体式喷管521的出口端212之间还设置压环225。相应地，孔网221的周边上设有连接部224。压环225将该连接部224压在孔网骨架222的端部内壁上，从而能够牢固地固定孔网221，使得孔网221在经受高压水流冲击的时候不会从一体式喷管521的出口端212上脱落。在替代的实施例中，孔网221也可以利 用其它结构进行固定，例如用卡簧卡住孔网。在一种或多种实施例中，压环225上也设有多个压环孔226。在喷射水流流量不大的情况下，这些压环孔226可以用于将空气吸入并与水流混合。在喷射水流流量比较大时，允许部分水从这些压环孔226溢出，由此不仅能够帮助清洁孔网，而且还能阻止多余的水逆流通过进气通道而导致无法通过这些进气通道吸入空气。
图10是沿着图6的剖面线A-A截取的本发明微气泡喷头在第二实施方式中的另一种实施例的剖视图。如图10所示，在该实施例中，变直径通道部217独立于一体式喷管521通过注塑形成。另外，在该实施例中，孔网骨架222与一体式喷管的出口端212也是通过螺纹连接部300固定在一起，并且在螺纹连接部300中形成螺纹进气通道216’，例如是形成在外螺纹与内螺纹之间的间隙。因此，在该实施例中，进气通道不仅包括位于一体式喷管521外壁上的进气孔216，还包括螺纹进气通道216’。在替代的实施例中，喷头52的进气通道也可以只包括设置在一体式喷管521的出口端与微气泡起泡器之间的进气通道。
第三实施方式
为了解决现有微气泡产生器的结构复杂、制造成本高的问题，本发明提供了一种微气泡喷头52。该微气泡喷头52包括一体式喷管521和固定在一体式喷管521的出口端212上的微气泡起泡器522(参见图3-8)。在一体式喷管521内设有直径变小锥形通道部217。在直径变小锥形通道部217内沿着水流方向C形成有相互平行的多个直径变小锥形通道218，使得多股水流能够在多个直径变小锥形通道218中形成并且从多个直径变小锥形通道218的出口218b膨胀地喷出以在出口218b附近产生负压。在一体式喷管521上还设有进气通道，进气通道定位成靠近出口218b，使得空气在负压下能够从进气通道吸入并且与多股水流混合产生气泡水，气泡水通过微气泡起泡器522形成微气泡水。因此，相比于现有技术的微气泡发生器，本发明微气泡喷头的部件数量和结构都被大大简化，并且微气泡喷头的制造成本也大幅降低，同时微气泡喷头又具有良好的产生微气泡的性能。
在本文中提及的“直径变小锥形通道”是指每个通道沿着水流方向C直径逐渐变小而形成大致锥形的通道。
本发明微气泡喷头52可以应用在洗涤领域，杀菌领域，或者其它需要微气泡的领域。例如，本发明微气泡喷头52既能够应用到洗涤设备中，也能够结合到卫浴水龙头或花洒等装置中。
因此，本发明还提供一种洗涤设备，该洗涤设备包括本发明的微气泡喷头52。该微气泡喷头52设置成在该洗涤设备内产生微气泡水。通过微气泡喷头在洗涤设备内产生含有大量微气泡的微气泡水，不仅能够提高洗涤设备的洗净能力，而且能够减少洗涤剂的用量并降低洗涤剂在例如衣物中的残留量，从而不仅有利于用户的健康，而且还能改善用户的体验。
参照图1，图1是本发明具有微气泡喷头的洗涤设备的一种实施例的结构示意图。在该实施例中，洗涤设备为一种波轮洗衣机1。替代地，在其它实施例中，洗涤设备可以是滚筒洗衣机或烘干一体机等。
如图1所示，波轮洗衣机1(以下简称洗衣机)包括箱体11。在箱体11的底部设有地脚14。箱体11的上部设置有盘座12，盘座12枢转连接有上盖13。在箱体11内设置有作为盛水桶的外桶21。在外桶21内设置有内桶31，内桶31的底部设置有波轮32，外桶21的下部固定有电机34，电机34通过传动轴33与波轮32驱动连接，在内桶31的侧壁上设有脱水孔311，通过这些脱水孔311洗涤水或来自衣物上的水能够从内桶31流出并进入外桶21。排水阀41设置在排水管42上，排水管42的上游端与外桶21的底部连通。该波轮洗衣机1还包括进水阀51和与进 水阀51连通的微气泡喷头52，微气泡喷头52被安装在外桶21的顶部上。水经由进水阀51进入微气泡喷头52以产生包含大量微气泡的微气泡水，微气泡喷头52将微气泡水先喷入洗涤剂盒以与洗涤剂(或其它衣物处理剂)混合，然后经由洗涤剂盒进入内桶31，用于衣物清洗。水中的微气泡在破碎过程中对洗涤剂产生撞击，并且微气泡通过携带的负电荷也能够吸附洗涤剂，因此微气泡能够增加洗涤剂与水的混合程度，从而降低洗涤剂的用量并减少洗涤剂在衣物上的残留量。另外，微气泡在内桶31内也会撞击衣物上的污渍，并且会吸附产生污渍的异物。因此，微气泡还增强了洗衣机的去污性能。可选地，微气泡喷头还可以直接将携带大量微气泡的微气泡水喷入洗衣机的外桶21或内桶31，以进一步降低洗涤剂的用量并增强洗衣机的清洁能力。
参照图2，图2是本发明具有微气泡喷头的洗涤设备的另一种实施例的结构示意图。在该实施例中，洗涤设备为一种滚筒洗衣机9。
如图2所示，滚筒洗衣机9包括外壳91和位于外壳底部的地脚98。在外壳91的顶部设有上台面板94。外壳91的前侧(面对用户的操作侧)上设有允许用户向滚筒洗衣机内装填衣物等的门体97，而门体97上还设有能够看到洗衣机内部的观察窗96。在观察窗96与外壳91之间还设置密封窗垫961，并且该密封窗垫961固定在外壳91上。滚筒洗衣机9的控制面板95布置在外壳91的前侧的上部，以便于用户的操作。在外壳91的内部则布置有外筒92和内筒93。内筒93定位在外筒92的内部。内筒93通过传动轴932和轴承933连接到电机931(例如直驱电机)。在外壳91的后侧的上部上设有进水阀51，该进水阀51通过水管连接到微气泡喷头52。如图2所示，微气泡喷头52定位靠近外壳91的前侧上部，并且位于控制面板95的下方。类似于上述实施例，水经由进水阀51通过水管进入微气泡喷头52以产生包含大量微气泡的微气泡水，微气泡喷头52将微气泡水先喷入洗涤剂盒以与洗涤剂(或其它衣物处理剂)混合，然后经由洗涤剂盒进入内筒93，用于衣物清洗。可选地，微气泡喷头52还可以直接将携带大量微气泡的微气泡水喷入洗衣机的外筒92或内筒93，以进一步降低洗涤剂的用量并增强洗衣机的清洁能力
参照图3-图6，图3-图6是本发明微气泡喷头的实施例的示意图，其中，图3是本发明微气泡喷头的实施例的立体示意图，图4是图3所示的本发明微气泡喷头的实施例的俯视图，图5是图3所示的本发明微气泡喷头的实施例的左视图，以及图6是图3所示的本发明微气泡喷头的实施例的正视图。如图3-6所示，在一种或多种实施例中，本发明微气泡喷头52包括一体式喷管521。在一体式喷管521的出口端212上固定有微气泡起泡器522，微气泡起泡器522配置成能够在气泡水流过其时切割和混合气泡水而产生含有大量微气泡的微气泡水。
参照图3，在一种或多种实施例中，一体式喷管521具有进口端211和出口端212。在出口端212上固定有微气泡起泡器522，而进口端211则用于连接到外部水源。可选地，在进口端211上可设置止脱部213，例如围绕进口端211的外壁径向向外隆起的止脱筋或者进口端211的外壁向内凹进的环形沟槽结构，能够防止一体式喷管521从其所连接的提供水源的管道上脱落。
继续参照图3，在一种或多种实施例中，在一体式喷管521的外壁上设有第一固定安装部214A，第二固定安装部214B，以及定位部215，用于将微气泡喷头52定位和固定到预定位置。
参照图4-图6，第一固定安装部214A和第二固定安装部214B对称地定位在一体式喷管521的外壁上，并且位于一体式喷管521的中部。定位部215则为长条肋，从一体式喷管521的外壁径向向外突出，并且沿着一体式喷管521的纵向延伸。第一固定安装部214A和第二固定 安装部214B分布在定位部215的两侧。可选地，在一体式喷管521上只设置一个固定安装部，而定位部215也可以采用其它合适的形式。
在一种或多种实施例中，第一和第二固定安装部214A，214B为螺钉孔结构，以通过螺钉将喷头52固定到目标位置。然而，固定安装部可采用任何合适的其它形式的连接结构，例如卡扣连接结构、焊接连接结构等。
图11是沿着图6的剖面线A-A截取的本发明微气泡喷头在第三实施方式中的一种实施例的剖视图。如图11所示，在一体式喷管521内，沿着水流方向C设有直径变小锥形通道部217。在一种或多种实施例中，直径变小锥形通道部217与一体式喷管521形成为一体，例如通过一体注塑成型。在替代地实施例中，直径变小锥形通道部217独立于一体式喷管521形成，然后被插入到一体式喷管521内并且被卡在一体式喷管521中。替代地，独立形成的直径变小锥形通道部217也能够被压合在一体式喷管521中。
参照图11，在直径变小锥形通道部217内设有多个相互平行的直径变小锥形通道218。在一种或多种实施例中，直径变小锥形通道218的数量为2-16个，这些直径变小锥形通道围绕一体式喷管521的中心线按照环形形式均匀地分布。替代地，直径变小锥形通道218的数量可以为6-9个。可选地，这些直径变小锥形通道也可以以环形以外的形式布置，并且可以不是均匀分布地。在一种或多种实施例中，所有直径变小锥形通道218彼此相同。替代地，这些直径变小锥形通道218也可以具有不同的设置，例如在同一径向位置上，靠近一体式喷管521的中心的直径变小锥形通道的横截面大于远离一体式喷管521的中心的直径变小锥形通道的横截面。
继续参照图11，每个直径变小锥形通道218都包括进口218a和出口218b。从一体式喷管521的进口端211流入的水流从每个直径变小锥形通道218的进口218a进入相应通道并且因此被分成多股水流。这多股水流在对应的直径变小锥形通道218内由于流道截面逐渐缩小被加压，并且当这多股水流从多个直径变小锥形通道218的出口218b喷出时被快速地膨胀，因此在多个直径变小锥形通道218的出口218b附近产生负压区。
如图11所示，一体式喷管521的外壁上形成有作为进气通道的多个进气孔216。这些进气孔216围绕一体式喷管521的外壁布置成两个环形，并且这些进气孔216定位都靠近直径变小锥形通道218的出口218b，因此处于负压区内。在负压的作用下，大量外部空气能够从进气孔216被吸入一体式喷管521并且与从多个直径变小锥形通道218喷出的多股水流混合而产生气泡水。气泡水然后流向下游的微气泡起泡器522以形成微气泡水。在替代的实施例中，根据需要，可以设置更多或更少的进气孔，并且能够以其它方式排布，例如以交错方式排列。
位于一体式喷管521的出口端212上的微气泡起泡器522包括孔网221和孔网骨架222。孔网221通过孔网骨架222附接到一体式喷管521的出口端212上。
在一种或多种实施例中，孔网221具有至少一道细孔的直径达微米级。优选地，细孔的直径在0～1000微米之间；更优选地，细孔的直径在5～500微米之间。孔网221可以是塑料栅栏，金属网，高分子材料网，或者其它合适的孔网结构。塑料栅栏通常是指高分子栅栏，其由高分子材料一体注塑成型，或者先将高分子材料制成板，再在该板上通过机加工产生微孔结构而形成塑料栅栏。高分子材料网通常是指通过先将高分子材料制成丝，再用这丝编织成的具有微孔结构的网。高分子材料网可以包括尼龙网，棉纶网，涤纶网，丙纶网等。替代地，孔网221可以是能够产生微气泡的其它孔网结构，例如由两个非微米级的蜂窝状结构组成的孔网结构。当气泡水流过孔网221时，孔网221对气泡水产生混合和切割的作用，从而产生微气泡水。
参照图11，孔网骨架222呈圆筒状以便能够套在一体式喷管521的出口端212上。在一种或多种实施例中，孔网骨架222与一体式喷管的出口端212通过螺纹连接部300固定在一起。例如，在孔网骨架222的内壁上形成内螺纹，并且在出口端212的外壁上形成外螺纹，该内螺纹与外螺纹啮合在一起。在替代的实施例中，孔网骨架222可以采用其它合适的形式，例如压板的形式，并且通过其它连接方式与一体式喷管521的出口端连接，例如焊接的方式。可选地，孔网还可以直接形成在一体式喷管的出口端212上。
在一种或多种实施例中，在孔网骨架222和一体式喷管的出口端212的连接部之间也可以形成进气通道，例如在彼此啮合的内螺纹和外螺纹之间预留设定的间隙可以充当螺纹进气通道216’。该进气通道可以单独成为本发明微气泡喷头的进气通道，也可以与进气孔216结合起来使用。
如图3-6和图11所示，在一种或多种实施例中，孔网骨架222沿着其外周设有多个溢流孔223，并且这些溢流孔定位靠近孔网221。当气泡水不能及时从孔网221通过时，多余的气泡水能够从溢流孔223流出，从而能够防止多余的水回流而淹没进气孔216。因此，溢流孔223能够阻止因进气孔216被堵而使空气无法被吸入一体式喷管因此无法产生微气泡水的情形。在替代的实施例中，根据需要，可以设置更多或更少的溢流孔223。
继续参照图11，在一种或多种实施例中，在孔网骨架222与一体式喷管521的出口端212之间还设置压环225。相应地，孔网221的周边上设有连接部224。压环225将该连接部224压在孔网骨架222的端部内壁上，从而能够牢固地固定孔网221，使得孔网221在经受高压水流冲击的时候不会从一体式喷管521的出口端212上脱落。在替代的实施例中，孔网221也可以利用其它结构进行固定，例如用卡簧卡住孔网。在一种或多种实施例中，压环225上也设有多个压环孔226。在喷射水流流量不大的情况下，这些压环孔226可以用于将空气吸入并与水流混合。在喷射水流流量比较大时，允许部分水从这些压环孔226溢出，由此不仅能够帮助清洁孔网，而且还能阻止多余的水逆流通过进气通道而导致无法通过这些进气通道吸入空气。
图12是沿着图6的剖面线A-A截取的本发明微气泡喷头在第三实施方式中的另一种实施例的剖视图。如图12所示，在该实施例中，直径变小锥形通道部217独立于一体式喷管521通过注塑形成。另外，在该实施例中，孔网骨架222与一体式喷管的出口端212也是通过螺纹连接部300固定在一起，并且在螺纹连接部300中形成螺纹进气通道216’，例如是形成在外螺纹与内螺纹之间的间隙。因此，在该实施例中，进气通道不仅包括位于一体式喷管521外壁上的进气孔216，还包括螺纹进气通道216’。在替代的实施例中，喷头52的进气通道也可以只包括设置在一体式喷管521的出口端与微气泡起泡器之间的进气通道。
至此，已经结合附图所示的优选实施方式描述了本发明的技术方案，但是，本领域技术人员容易理解的是，本发明的保护范围显然不局限于这些具体实施方式。在不偏离本发明的原理的前提下，本领域技术人员可以对来自不同实施例的技术特征进行组合，也可以对相关技术特征作出等同的更改或替换，这些更改或替换之后的技术方案都将落入本发明的保护范围之内。
