Description
本創作有關於一種氣泡細化結構,尤指一種遞進射孔式粉碎細化結構。This creation relates to a bubble refinement structure, especially a progressive perforation type pulverization refinement structure.
現有技術中,在水產養殖、廢水處理、化學反應、醫療衛生、植物栽培以及工業清洗與除垢等領域,常常需要將氣體混入水媒體中以獲得含氣泡的水工質,目的是增加空氣與水的接觸面積,來增進各種處理功效,最顯而易見的是提高了清洗除垢的能力。 近年來,含氣泡的水工質還被應用到日常生活領域, 可以用於浸泡或者沖洗蔬菜、水果、碗碟,也可以用於沐浴與淋洗。 為了使水中含有氣泡,可以借助外部動力將空氣壓入,如壓縮機和氣泵;也可以利用水流動產生的負壓將空氣吸入,如文丘裡管結構或渦旋結構的氣泡獲得裝置。 文丘裡管結構的氣泡獲得裝置主要利用了水流速度增加而水壓降低的原理。文丘裡管結構的氣泡獲得裝置通過設置漸縮的管路,使得水流增速並在管路的喉口處形成低於外部大氣的真空區,籍此真空區將外部空氣吸入到管路內。 渦旋結構的氣泡獲得裝置主要利用了離心運動的中心壓力低的原理。渦旋結構的氣泡獲得裝置使得水流旋轉並產生離心作用,進而在旋轉中心處形成低於外部大氣的真空區,真空區將外部空氣吸入到管路內。 文丘裡管結構具體可以參見臺灣專利TW20170212400U微氣泡產生器,渦旋結構具體可以參見中國專利CN102958589B微氣泡產生裝置和CN203916477U微氣泡產生裝置。微氣泡產生器、微氣泡產生裝置,可以統稱為微氣泡獲得裝置。 上述微氣泡獲得裝置可以使水中含有直徑數十微米乃至數微米以下的微氣泡,進而,使得延長氣泡在水中的滯留時間,同時,使得氣泡的表面積與體積的比值增大,使氣泡具有較高的吸附特性,因而,清潔去垢能力可以得到提升。 渦旋結構相對文丘裡管結構的優點是減少氣泡獲得裝置的長度,而且,對水流量的變化不敏感。因而,現有的微氣泡獲得裝置多採用渦旋結構。 然而,現有設計中,產生微氣泡通常是使用高目數的過濾網,或者,設置有複數個切孔的錐形網,但是,前者容易發生堵塞,後者產生的氣泡難以達到微納米級別。In the prior art, in the fields of aquaculture, wastewater treatment, chemical reaction, medical sanitation, plant cultivation, industrial cleaning and descaling, it is often necessary to mix gas into water medium to obtain water-containing working medium with bubbles, in order to increase air and The contact area of the water to enhance various treatments, the most obvious is to improve the ability to clean and descale. In recent years, water-containing fluids have been applied to daily life, and can be used to soak or rinse vegetables, fruits, dishes, and baths and rinses. In order to make the water contain air bubbles, the air can be pushed in by external power, such as a compressor and an air pump; or the air can be sucked in by the negative pressure generated by the flow of water, such as a venturi structure or a vortex structure bubble obtaining device. The bubble obtaining device of the venturi tube structure mainly utilizes the principle that the water flow velocity is increased and the water pressure is lowered. The bubble obtaining device of the venturi tube structure allows the water flow to increase in speed and form a vacuum region below the external atmosphere at the throat of the pipe by providing a tapered pipe, whereby the vacuum region draws outside air into the pipe. The bubble obtaining device of the vortex structure mainly utilizes the principle that the center pressure of the centrifugal motion is low. The bubble obtaining means of the vortex structure causes the water flow to rotate and centrifugally, thereby forming a vacuum zone at the center of rotation lower than the outside atmosphere, and the vacuum zone draws outside air into the pipe. For details of the structure of the venturi tube, refer to the Taiwan patent TW20170212400U microbubble generator. For the vortex structure, please refer to the Chinese patent CN102958589B microbubble generating device and the CN203916477U microbubble generating device. The microbubble generator and the microbubble generating device may be collectively referred to as a microbubble obtaining device. The microbubble obtaining device can make the water contain microbubbles having a diameter of several tens of micrometers or even several micrometers or less, thereby further prolonging the residence time of the bubbles in the water, and at the same time, increasing the ratio of the surface area to the volume of the bubbles, so that the bubbles are higher. The adsorption characteristics, therefore, the cleaning and detergency ability can be improved. The advantage of the vortex structure relative to the venturi structure is that it reduces the length of the bubble acquisition device and is not sensitive to changes in water flow. Therefore, the existing microbubble obtaining device mostly employs a vortex structure. However, in the prior art, the generation of microbubbles is usually a filter using a high mesh number, or a conical mesh provided with a plurality of cut holes, but the former is prone to clogging, and the bubbles generated by the latter are difficult to reach the micro-nano level.
本創作旨在解決上述所提及的技術問題,提供一種遞進射孔式粉碎細化結構,不易堵塞,而且,可以穩定產生大量微納米級別的氣泡。 本創作是透過以下的技術方案實現的:一種遞進射孔式粉碎細化結構,包括薄壁狀的初級粉碎細化件和次級粉碎細化件,初級粉碎細化件和次級粉碎細化件均設置有若干用於將一流體內氣泡粉碎細化的微孔道,初級粉碎細化件和次級粉碎細化件配合形成緩衝空間,初級粉碎細化件和次級粉碎細化件的微孔道至少四分之一沿流體流動方向重疊或重合設置。 在一實施例中,該微孔道的等效直徑為0.2mm至0.8mm。 在一實施例中,該初級粉碎細化件呈錐形設置,錐形的尖部朝背向該次級粉碎細化件的方向設置。 在一實施例中,該次級粉碎細化件呈錐狀設置,錐形的尖部朝背向該初級粉碎細化件的方向設置。 在一實施例中,該初級粉碎細化件或該次級粉碎細化件呈棱錐形設置。 在一實施例中,該初級粉碎細化件的外邊緣形成一容置該次級粉碎細化件的第一環。 在一實施例中,該次級粉碎細化件的外邊緣設置有一定位邊。 在一實施例中,該遞進射孔式粉碎細化結構更包括一末級粉碎細化件,該末級粉碎細化件和該次級粉碎細化件之間形成一過渡空間。 在一實施例中,該初級粉碎細化件與末級粉碎細化件連接並夾緊固定該次級粉碎細化件。 與現有技術相比,本創作提供一種遞進射孔式粉碎細化結構透過設置薄壁的初級粉碎細化件,代替高目數的過濾網,一方面減少了孔的數量,可以使顆粒可以沉積,延緩堵塞,從而使得微氣泡獲得裝置的免維護時間得以延長;另一方面,在微孔道的節流和束流作用下,水流經過微孔道後呈噴射狀的紊流,存在碰撞、擾動和震盪激勵,可以將粗大的氣泡被擊碎,從而獲得較細小的氣泡,再透過設置次級粉碎細化件,進一步的將氣泡細化呈微納米級別,滿足需求。此外,還透過在初級粉碎細化件和次級粉碎細化件之間形成緩衝空間,使得氣泡在經過初級粉碎細化件後可以重複的碰撞、擾動和振動;另外,還透過使初級粉碎細化件和次級粉碎細化件的微孔道至少四分之一沿流體流動方向重疊或重合設置,使得氣泡能夠較為順利的經由初級粉碎細化件的微孔道流向次級粉碎細化件的微孔道,從而減少水流的流動阻力,避免遞進射孔式粉碎細化結構處產生較大的背壓阻力,不影響微氣泡獲得裝置的進氣量。The present invention aims to solve the above-mentioned technical problems, and provides a progressive perforating pulverization refining structure which is not easy to block, and can stably generate a large number of micro-nano-level bubbles. The creation is achieved through the following technical solutions: a progressive perforating pulverization refining structure, including a thin-walled primary pulverizing refining piece and a secondary pulverizing refining piece, a primary pulverizing refining piece and a secondary pulverizing piece. The chemical parts are provided with a plurality of micro-channels for refining the bubbles in the first-class body, and the primary pulverizing refining parts and the secondary pulverizing refining parts are combined to form a buffer space, the primary pulverizing refining parts and the secondary pulverizing refining parts. At least a quarter of the microchannels overlap or overlap in the direction of fluid flow. In one embodiment, the microchannels have an equivalent diameter of from 0.2 mm to 0.8 mm. In one embodiment, the primary comminuted refining member is tapered and the tapered tip is disposed in a direction away from the secondary comminution refining member. In one embodiment, the secondary comminution refining member is disposed in a tapered shape with the tapered tip disposed in a direction away from the primary comminution refining member. In an embodiment, the primary comminution refining member or the secondary comminution refining member is disposed in a pyramid shape. In one embodiment, the outer edge of the primary comminution refining member defines a first ring that receives the secondary comminution refining member. In an embodiment, the outer edge of the secondary comminution refining member is provided with a positioning edge. In one embodiment, the progressive perforating pulverization refining structure further includes a final pulverizing refining member, and a transition space is formed between the final pulverizing refining member and the secondary pulverizing refining member. In one embodiment, the primary comminution refining member is coupled to the final pulverizing refining member and clamps the secondary pulverizing refining member. Compared with the prior art, the present invention provides a progressive perforating pulverized refining structure through the provision of a thin-walled primary pulverizing refining member instead of a high-mesh filter net, on the one hand, the number of holes is reduced, and the particles can be made Deposition, delay clogging, so that the maintenance-free time of the micro-bubble obtaining device is prolonged; on the other hand, under the action of the throttling and beam flow of the micro-channel, the water flows through the micro-channel and is spray-like turbulent flow, and there is collision and disturbance. And the shock excitation, the coarse bubbles can be crushed to obtain finer bubbles, and then the secondary pulverization refinement is provided, and the bubbles are further refined to a micro-nano level to meet the demand. In addition, by forming a buffer space between the primary pulverizing refining member and the secondary pulverizing refining member, the bubbles can repeatedly collide, perturb and vibrate after passing through the primary pulverizing refining member; At least one quarter of the microchannels of the chemical element and the secondary pulverization refining member are overlapped or overlapped in the fluid flow direction, so that the bubbles can smoothly flow through the micropores of the primary pulverizing refining member to the secondary pulverizing refining member. The micro-channels, thereby reducing the flow resistance of the water flow, avoiding a large back pressure resistance at the progressive perforation-type pulverization refinement structure, and do not affect the intake air amount of the micro-bubble obtaining device.
以下將結合實施例和附圖對本創作的構思、具體結構及產生的技術效果進行清楚、完整地描述,以充分地理解本創作的目的、特徵和效果。 顯然,所描述的實施例只是本創作的一部分實施例,而不是全部實施例,基於本創作的實施例,本領域的技術人員在不付出創造性勞動的前提下所獲得的其它實施例,均屬於本創作的保護範圍。 另外,文中所提到的所有連接關係,並非單指構件直接相接,而是指可根據具體實施情況,透過添加或減少連接輔件,來組成更優的連接結構。本創作中的各個技術特徵,在不互相矛盾衝突的前提下可以交互組合。 如第1圖、第4圖所示,本創作一種微氣泡獲得裝置,包括一第一本體1,該第一本體1設置有一進水道2、一出水道、一將該進水道2和出水道連通的渦旋腔3及一連通該渦旋腔3的進氣道11,出水道設置有產生微氣泡的結構。如圖1中,中心線分別為進水道2的軸線和渦旋腔3的軸線。 該進氣道11可以連接壓縮機和氣泵等,進而使用外部動力將空氣壓入渦旋腔3。當然,該進氣道11也可以利用水流動產生的負壓將空氣吸入。 其中對於該渦旋腔3來說,該第一本體1設置有一用於形成該渦旋腔3的第一側壁3b和一第一底壁3a,該第一側壁3b設置有一連通該渦旋腔3的進水孔12a,該進水孔12a位於朝向偏離該渦旋腔3的中心,以使得水流經進水孔12a後產生渦旋流動。 該進水道2設置在該第一底壁3a上,該進氣道11包括一沿該渦旋腔3軸線方向設置的第一氣道與一沿垂直於該渦旋腔3軸線方向設置的第二氣道,該第一氣道與該第二氣道連通,該第二氣道連通外界,該第一氣道連通該渦旋腔3,方便製造,而且,不影響微氣泡裝置的安裝使用。 對於該第一本體1來說,該第一本體1在靠近該進水道2的一端可以安裝有或一體成型的製造有一連接頭,使得微氣泡獲得裝置可以固定在水龍頭上。 當然,該第一本體1也可以安裝在一水管內,該第一本體1與水管通過密封圈密封,使得水流進入該進水道2,然後經由該渦旋腔3和出水道流出。這時候,前述進水道2可以是水管靠近該第一本體1的水道部分,且該第一本體1上可以省略該進水道2。 而常規的渦旋腔的軸線與進水道的軸線是重合的,後續簡稱為正置的渦旋腔或正置的渦旋結構,這就導致微氣泡獲得裝置具有了的狹窄的環狀進水口,阻礙水的流動,導致吸氣困難,然而加大環狀進水口的尺寸還使得微氣泡獲得裝置的直徑增大,但難以適用於常規的水管規格。 當然,這裡有關正置和偏置的渦旋結構的有益效果和缺點的論述,並不影響正置或偏置的渦旋結構與後下文本創作的遞進射孔式粉碎細化結構的結合,也就是說,正置或偏置的渦旋結構是均能夠與下文本創作的遞進射孔式粉碎細化結構組合形成前述微氣泡獲得裝置。 為解決上述正置的渦旋腔3所帶來的問題,如圖1、圖2所示,可以使該渦旋腔3的軸線與進水道2的軸線係偏置設置,該渦旋腔3設置有一連通該進水道2的進水口12,該進水口12設置於進水道2軸線背向渦旋腔3軸線一側,也即,採用偏置渦旋結構。 於本實施例的微氣泡獲得裝置透過使渦旋腔3的軸線與進水道2的軸線偏置設置,使進水口12設置於進水道2軸線背向渦旋腔3軸線一側,使得連通該渦旋腔3的進水口12係由狹窄的環狀變成月牙狀或柱狀,從而避免水流從狹窄縫隙中通過,因而可以增加水流的徑向尺寸,減少水流阻力,方便水流流入渦旋腔3內,這就使得微氣泡獲得裝置的直徑不增加,甚至可以減少,因此,微氣泡獲得裝置可以小型化,方便的連接在水管上或設置在水管內部,具有良好的通用性。 為進一步的說明本實施例所產生的良好有益效果,現進行詳細的論述。 目前家庭用水的管路主流管徑主要有外徑28mm和外徑22mm兩種型號,以外徑28mm的管路為例,如果氣泡發生裝置要做成內置式的話,那麼它的外徑就被要求不能超過24.5mm。這就是說,進水口12只能設置在一個寬度不超過2.5mm的環形區域內,這就使得進水口12的面積較小,或者與常規的圓孔狀的進水口12相比,進水口12的外輪廓長度增加,對水流流動產生阻礙,因此,導致背壓劇增而影響到渦旋的吸氣效果,甚至還會造成管路流量大幅下降。 因而,現有的正置式渦旋腔3結構很難內置進28mm管徑的管路之內。 與現有設計產生鮮明對比的是,本創作係採用偏置的渦旋腔3,且由於渦旋腔3偏置,該渦旋腔3的軸線與進水道2的軸線是偏置了一個距離,這個距離讓進水口12可以佈置在一個月牙狀的區域內,獲得3mm至4mm的半徑差,進水口12可以由狹窄的長條形向橢圓形或圓形靠近,縮小進水口12的外輪廓長度,方便水流通過進水口12,而不需要增加第一本體1的外直徑,換句話來說,偏置的渦旋腔3可以使得微氣泡獲得裝置的體積和佔用空間變小,以便於內置在家用水管內。 如圖3所示,作為圖1的微氣泡獲得裝置在一替代實施例,可以使該渦旋腔3為若干個,該進水口12的數量與渦旋腔3的數量是對應設置。也即,透過將大渦旋腔3變更成多個小渦旋腔3,進而,形成多個圓孔狀的進水口12,同樣可以改變進水口12狹窄的情況。 作為本創作微氣泡獲得裝置的進一步拓展,該第一本體1設置有一蓋合該渦旋腔3的束流件14,該束流件14設置有一將該渦旋腔3和出水道連通的出水孔13,該出水孔13的橫截面積沿水流方向減少,使得可以使空氣與水充分混合產生氣泡。另外,該出水孔13的橫截面積變化還可以對水流產生加速作用,壓縮氣泡和促進氣泡破碎。 為簡化製造,可以使該束流件14的外輪廓與出水道匹配設置,也即束流件14是單獨製造的,不增加渦流腔的製造難度。 當然,也可以使該束流件14與第一側壁3b一體製造,但製造上需要進行改進,該第一底壁3a與第一側壁3b需要分體製造。 為順利的使水產生渦旋流動,可以使該進水孔12a朝向沿渦旋腔3的切向設置。 為避免進水孔12a的孔徑受限進而導致水流流量減少,可以使進水孔12a的數量有兩個,也即設置一副進水孔12b,使得進水孔12a的總面積不減少或增大。 為解決現有技術中過濾網易堵塞以及錐形網產生的微氣泡級別不夠的問題,如圖1、圖4、圖5所示,本創作之該微氣泡獲得裝置還採用了一種遞進射孔式粉碎細化結構,當然,本創作之該遞進射孔式粉碎細化結構不僅適用於正置渦旋結構的微氣泡獲得裝置,也可以適用於偏置渦旋結構的微氣泡獲得裝置。 具體的,本創作之該遞進射孔式粉碎細化結構包括一薄壁狀的初級粉碎細化件4和一次級粉碎細化件5,該初級粉碎細化件4和次級粉碎細化件5均設置有若干(或複數)用於將流體內氣泡粉碎細化的微孔道6,其中該初級粉碎細化件4和次級粉碎細化件5配合形成一緩衝空間8,該初級粉碎細化件4和次級粉碎細化件5的微孔道6至少四分之一沿流體流動方向重疊或重合設置,依據上述微氣泡獲得裝置,流體流動方向是流體所在通道的軸線方向。 本實施例係一種遞進射孔式粉碎細化結構透過設置前述薄壁的初級粉碎細化件4,代替高目數的過濾網,一方面減少了孔的數量,且還可以使顆粒可以沉積,延緩堵塞,從而使得微氣泡獲得裝置的免維護時間得以延長;另一方面,在微孔道6的節流和束流作用下,水流經過微孔道6後呈噴射狀的紊流,存在碰撞、擾動和震盪激勵,可以將粗大的氣泡被擊碎,從而獲得較細小的氣泡,再透過設置前述次級粉碎細化件5,進一步的將氣泡細化呈微納米級別,滿足需求。此外,還透過在初級粉碎細化件4和次級粉碎細化件5之間形成該緩衝空間8,使得氣泡在經過初級粉碎細化件4後可以重複的碰撞、擾動和振動;另外,還透過使初級粉碎細化件4和次級粉碎細化件5的微孔道6至少四分之一沿流體流動方向重疊或重合設置,使得氣泡能夠較為順利的經由初級粉碎細化件4的微孔道6流向次級粉碎細化件5的微孔道6,從而減少水流的流動阻力,避免遞進射孔式粉碎細化結構處產生較大的背壓阻力,不影響微氣泡獲得裝置的進氣量。 具體的,該遞進射孔式粉碎細化結構採用設置該初級粉碎細化件4和次級粉碎細化件5的方式,利用開設的微孔道6作為流體工質的出流通道,並以此構成具有兩級遞進射孔特點的粉碎細化結構。 其中,該初級粉碎細化件4上的微孔道6為一第一級射孔,該次級粉碎細化件5上的微孔道6構成為一第二級射孔,當混雜有氣泡的流體工質經由該第一級射孔時,由於微孔道6的節流效應和束流作用而使得其流動具有噴射流的特點,此時流體的流速加快並具備紊流流動的特徵。 在紊流流動的碰撞、擾動和震盪的激勵下,粗大的氣泡被擊碎,從而獲得較細小的氣泡水,然後,較細小的氣泡被該第二級射孔進一步粉碎細化,並最終成為微氣泡。 當然,為了使該微氣泡獲得裝置適用於安裝在水龍頭末端的情況,還可以設置有一末級粉碎細化件9,除了可以進一步細化氣泡,還可以是水穩定流出,不影響出水效果。 為了提高該微孔道6破碎氣泡的能力,可以使微孔道6直徑或/和它們的等效直徑為0.2mm至0.8mm,否則產生的氣泡過大或者造成水流量不足。等效直徑可以通過S= πd 2/4進行計算,S為微孔道6的橫截面積,也就是說,該微孔道6可以採用非圓結構,如三角形、橢圓形、多邊形和其它各種異形。 為了增強該初級粉碎細化件4的強度,同時,使水流能夠沿初級粉碎細化件4的表面流動,進而,使氣泡被微孔道6以切割的方式粉碎,可以使初級粉碎細化件4呈錐形設置,錐形的尖部朝背向次級粉碎細化件5的方向設置。 為了能夠形成該緩衝空間8同時不增加零件數量和增加微氣泡獲得裝置的長度,可以使次級粉碎細化件5呈錐狀設置,錐形的尖部朝背向初級粉碎細化件4的方向設置。 為了使得水流能夠平行的沿初級粉碎細化件4或次級粉碎細化件5的表面流動,可以初級粉碎細化件4或次級粉碎細化件5呈棱錐形設置。同時,初級粉碎細化件4或次級粉碎細化件5呈棱錐形設置,還便於兩者的微孔道6重合或重疊。 為了確保初級粉碎細化件4和次級粉碎細化件5上微孔道6的相對位置滿足需要,可以使初級粉碎細化件4的外邊緣形成一容置該初級粉碎細化件4的第一環41。 為避免次級粉碎細化件5在第一環41內偏轉,也即,為了次級粉碎細化件5能夠準確的安裝在第一環41內,可以使次級粉碎細化件5的外邊緣設置有一定位邊51。 對於末級粉碎細化件9來說,該末級粉碎細化件9和次級粉碎細化件5之間形成一過渡空間10,以使水流穩定。 為進一步降低成本和減少零部件數量,該初級粉碎細化件4與末級粉碎細化件9連接並夾緊固定該次級粉碎細化件5。 以上實施例不局限於該實施例自身的技術方案,實施例之間可以相互結合成新的實施例。以上實施例僅用以說明本實用新型的技術方案而並非對其進行限制,凡未脫離本實用新型精神和範圍的任何修改或者等同替換,其均應涵蓋在本實用新型技術方案的範圍內。 The concept, the specific structure and the technical effects of the present invention will be clearly and completely described in conjunction with the embodiments and the accompanying drawings to fully understand the purpose, features and effects of the present invention. It is apparent that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present creation, other embodiments obtained by those skilled in the art without creative efforts belong to the embodiments. The scope of protection of this creation. In addition, all the connection relationships mentioned in the text are not directly connected to each other, but means that a better connection structure can be formed by adding or reducing connection accessories according to specific implementation conditions. The various technical features in this creation can be combined and combined without conflicting conflicts. As shown in FIG. 1 and FIG. 4, a microbubble obtaining device includes a first body 1 which is provided with a water inlet 2, a water outlet, a water inlet 2 and a water outlet. The communicating vortex chamber 3 and an inlet passage 11 communicating with the vortex chamber 3 are provided with a structure for generating microbubbles. As shown in Fig. 1, the center line is the axis of the inlet 2 and the axis of the swirl chamber 3, respectively. The intake passage 11 can be connected to a compressor, a gas pump, or the like, and then pressurizes the air into the swirl chamber 3 using external power. Of course, the intake passage 11 can also draw in air by the negative pressure generated by the flow of water. For the scroll chamber 3, the first body 1 is provided with a first side wall 3b for forming the scroll chamber 3 and a first bottom wall 3a, and the first side wall 3b is provided with a connection between the scrolls The water inlet hole 12a of the chamber 3 is located away from the center of the scroll chamber 3 so that the water flows through the water inlet hole 12a to generate a swirling flow. The water inlet 2 is disposed on the first bottom wall 3a, and the air inlet 11 includes a first air passage disposed along the axial direction of the scroll chamber 3 and a second air passage disposed perpendicular to the axial direction of the scroll chamber 3. The air passage, the first air passage is in communication with the second air passage, the second air passage is connected to the outside, and the first air passage communicates with the scroll chamber 3 to facilitate manufacture, and does not affect the installation and use of the microbubble device. For the first body 1, the first body 1 can be mounted or integrally formed at one end near the water inlet 2 to produce a connector, so that the microbubble obtaining device can be fixed on the faucet. Of course, the first body 1 can also be installed in a water pipe, and the first body 1 and the water pipe are sealed by a sealing ring so that water flows into the water inlet pipe 2, and then flows out through the swirling chamber 3 and the water outlet. At this time, the aforementioned water inlet 2 may be a water passage portion of the water pipe close to the first body 1, and the water inlet 2 may be omitted on the first body 1. Whereas the axis of the conventional scroll chamber coincides with the axis of the water inlet, which is hereinafter referred to as the upright scroll chamber or the upright scroll structure, which results in a narrow annular inlet for the microbubble obtaining device. The flow of water is impeded, resulting in difficulty in suction. However, increasing the size of the annular inlet also increases the diameter of the microbubble obtaining device, but it is difficult to apply to conventional water pipe specifications. Of course, the discussion of the beneficial effects and shortcomings of the vortex structure of the upright and offset does not affect the combination of the vortex structure of the upright or offset and the progressive perforation smash refinement structure created by the lower text. That is, the vortex structure of the upright or offset shape can be combined with the progressive perforation pulverization refinement structure of the lower text creation to form the aforementioned microbubble obtaining device. In order to solve the problem caused by the above-mentioned vortex chamber 3, as shown in FIG. 1 and FIG. 2, the axis of the vortex chamber 3 can be offset from the axis of the water inlet 2, and the vortex chamber 3 can be disposed. A water inlet 12 is provided which communicates with the water inlet 2, and the water inlet 12 is disposed on the side of the axis of the water inlet 2 facing away from the axis of the scroll chamber 3, that is, an offset scroll structure is employed. The microbubble obtaining device of the present embodiment is disposed such that the axis of the scroll chamber 3 is offset from the axis of the water inlet 2, so that the water inlet 12 is disposed on the side of the inlet channel 2 facing away from the axis of the scroll chamber 3, so that the water is connected. The water inlet 12 of the vortex chamber 3 is changed from a narrow ring shape to a crescent shape or a column shape, thereby preventing water flow from passing through the narrow gap, thereby increasing the radial size of the water flow, reducing the water flow resistance, and facilitating the flow of water into the vortex chamber 3 In this case, the diameter of the microbubble obtaining device is not increased or even reduced. Therefore, the microbubble obtaining device can be miniaturized, conveniently connected to the water pipe or disposed inside the water pipe, and has good versatility. In order to further illustrate the good beneficial effects produced by the present embodiment, a detailed discussion will now be made. At present, the mainstream pipe diameter of domestic water mainly has two types of outer diameter 28mm and outer diameter 22mm. For example, a pipe with an outer diameter of 28mm is used. If the bubble generating device is to be built-in, its outer diameter is required. Can not exceed 24.5mm. That is to say, the water inlet 12 can only be disposed in an annular region having a width of not more than 2.5 mm, which makes the water inlet 12 have a small area, or the water inlet 12 is compared with the conventional circular hole-shaped water inlet 12. The increase in the length of the outer contour hinders the flow of the water flow, thus causing a sharp increase in back pressure and affecting the inhalation effect of the vortex, and even causing a large drop in the flow rate of the pipeline. Therefore, the structure of the existing upright scroll chamber 3 is difficult to be built into the pipe of 28 mm diameter. In sharp contrast to the prior art, the author uses a biased vortex chamber 3, and the axis of the vortex chamber 3 is offset from the axis of the inlet 2 by a distance due to the vortex chamber 3 being biased. This distance allows the water inlet 12 to be arranged in a crescent-shaped area to obtain a radius difference of 3 mm to 4 mm, and the water inlet 12 can be narrowed to an elliptical or circular shape to narrow the outer contour length of the water inlet 12. The water flow is facilitated to pass through the water inlet 12 without increasing the outer diameter of the first body 1. In other words, the biased swirl chamber 3 can make the volume and space occupied by the microbubble obtaining device small, so as to be built in. In the domestic water pipe. As shown in FIG. 3, as an alternative embodiment, the microbubble obtaining device of FIG. 1 may have a plurality of the swirl chambers 3, and the number of the water inlets 12 is corresponding to the number of the swirl chambers 3. In other words, by changing the large scroll chamber 3 into a plurality of small scroll chambers 3, a plurality of water inlet ports 12 having a circular hole shape are formed, and the water inlet port 12 can be changed to be narrow. As a further development of the present microbubble obtaining device, the first body 1 is provided with a beam member 14 covering the scroll chamber 3, and the beam member 14 is provided with a water outlet for connecting the scroll chamber 3 and the water outlet. The hole 13, the cross-sectional area of the water outlet hole 13 is reduced in the direction of water flow, so that air and water can be sufficiently mixed to generate air bubbles. In addition, the change in the cross-sectional area of the water outlet hole 13 can also accelerate the water flow, compress the air bubbles and promote the bubble breakage. In order to simplify the manufacture, the outer contour of the beam member 14 can be matched with the water outlet, that is, the beam member 14 is separately manufactured without increasing the manufacturing difficulty of the vortex chamber. Of course, the beam member 14 can also be manufactured integrally with the first side wall 3b, but it needs to be improved in manufacturing. The first bottom wall 3a and the first side wall 3b need to be manufactured separately. In order to smoothly swirl the water, the water inlet hole 12a may be oriented toward the tangential direction along the scroll chamber 3. In order to prevent the aperture of the water inlet hole 12a from being restricted and the flow rate of the water flow to be reduced, the number of the water inlet holes 12a may be two, that is, a pair of water inlet holes 12b may be provided, so that the total area of the water inlet holes 12a is not reduced or increased. Big. In order to solve the problem that the filter mesh is easy to be blocked in the prior art and the microbubble level generated by the cone mesh is insufficient, as shown in FIG. 1 , FIG. 4 and FIG. 5 , the microbubble obtaining device of the present invention also adopts a progressive perforating type. The pulverized refining structure is of course applied not only to the microbubble obtaining device of the upright scroll structure but also to the microbubble obtaining device of the offset vortex structure. Specifically, the progressive perforating pulverizing refining structure of the present invention comprises a thin-walled primary pulverizing refining member 4 and a primary pulverizing refining member 5, the primary pulverizing refining member 4 and the secondary pulverizing refining The pieces 5 are each provided with a plurality (or plural) of micro-holes 6 for pulverizing the bubbles in the fluid, wherein the primary pulverizing refining member 4 and the secondary pulverizing refining member 5 cooperate to form a buffer space 8, the primary At least one quarter of the micropores 6 of the pulverizing refining member 4 and the secondary pulverizing refining member 5 are overlapped or overlapped in the fluid flow direction. According to the above microbubble obtaining device, the fluid flow direction is the axial direction of the passage in which the fluid is located. In this embodiment, a progressive perforating pulverized refining structure is provided through the provision of the thin-walled primary pulverizing refining member 4, instead of the high mesh filter screen, on the one hand, the number of holes is reduced, and the particles can be deposited. The clogging is delayed, so that the maintenance-free time of the microbubble obtaining device is prolonged; on the other hand, under the action of the throttling and beam current of the microporous channel 6, the water flows through the microchannel 6 and is sprayed turbulent, and there is a collision. The disturbance and the oscillating excitation can crush the coarse bubbles to obtain finer bubbles, and then pass through the secondary pulverization refining member 5 to further refine the bubbles to a micro-nano level to meet the demand. Further, the buffer space 8 is formed between the primary pulverization refining member 4 and the secondary pulverization refining member 5, so that the bubbles can repeatedly collide, disturb, and vibrate after passing through the primary pulverizing refining member 4; By at least one quarter of the micropores 6 of the primary pulverization refining member 4 and the secondary pulverization refining member 5 are overlapped or overlapped in the fluid flow direction, so that the bubbles can smoothly pass through the micro pulverization of the refining member 4 The tunnel 6 flows to the micropores 6 of the secondary pulverization refining member 5, thereby reducing the flow resistance of the water flow, avoiding a large back pressure resistance at the progressive perforation pulverization refining structure, and does not affect the microbubble obtaining device. The amount of intake air. Specifically, the progressive perforating pulverization refining structure adopts the manner of providing the primary pulverizing refining member 4 and the secondary pulverizing refining member 5, and uses the opened microporous passage 6 as an outflow passage of the fluid working medium, and In this way, a pulverized refinement structure having the characteristics of two-stage progressive perforation is constructed. Wherein, the micro-hole 6 on the primary pulverization refining member 4 is a first-stage perforation, and the micro-hole 6 on the secondary pulverization refining member 5 is formed as a second-stage perforation. When the fluid working medium passes through the first-stage perforation, the flow of the fluid has a jet flow due to the throttling effect and the beam action of the micro-channel 6, and the flow velocity of the fluid is accelerated and has the characteristic of turbulent flow. Under the turbulent flow collision, disturbance and shock excitation, the coarse bubbles are crushed to obtain finer bubble water, and then the finer bubbles are further pulverized and refined by the second-stage perforation, and finally become Micro bubbles. Of course, in order to make the microbubble obtaining device suitable for being installed at the end of the faucet, a final pulverizing refining member 9 may be provided, in addition to further refining the bubbles, the water may be stably discharged without affecting the effluent effect. In order to increase the ability of the microchannels 6 to break the bubbles, the diameters of the microchannels 6 or/and their equivalent diameters may be from 0.2 mm to 0.8 mm, otherwise the generated bubbles are too large or cause insufficient water flow. The equivalent diameter can be calculated by S = π d 2 /4, where S is the cross-sectional area of the microchannel 6, that is, the microchannel 6 can be a non-circular structure such as a triangle, an ellipse, a polygon, and others. Various shapes. In order to enhance the strength of the primary pulverization refining member 4, at the same time, the water flow can be caused to flow along the surface of the primary pulverization refining member 4, and further, the bubbles are pulverized by the micropores 6 in a cutting manner, so that the primary pulverization refining member can be made. 4 is arranged in a conical manner, the tapered tip being arranged facing away from the secondary comminution refining member 5. In order to be able to form the buffer space 8 without increasing the number of parts and increasing the length of the microbubble obtaining device, the secondary pulverizing refining member 5 may be disposed in a tapered shape with the tapered tip facing away from the primary pulverizing refining member 4. Direction setting. In order to allow the water flow to flow along the surface of the primary pulverization refining member 4 or the secondary pulverization refining member 5 in parallel, the primary pulverizing refining member 4 or the secondary pulverizing refining member 5 may be arranged in a pyramid shape. At the same time, the primary pulverizing refining member 4 or the secondary pulverizing refining member 5 is disposed in a pyramidal shape, and it is also convenient for the micropores 6 of the two to overlap or overlap. In order to ensure that the relative positions of the micropores 6 on the primary pulverizing refining member 4 and the secondary pulverizing refining member 5 are satisfactory, the outer edge of the primary pulverizing refining member 4 may be formed to accommodate the primary pulverizing refining member 4. First ring 41. In order to prevent the secondary pulverizing refining member 5 from being deflected in the first ring 41, that is, in order to accurately mount the secondary pulverizing refining member 5 in the first ring 41, the secondary pulverizing refining member 5 can be made outside. The edge is provided with a positioning edge 51. For the final stage pulverizing refining member 9, a transition space 10 is formed between the final pulverizing refining member 9 and the secondary pulverizing refining member 5 to stabilize the water flow. In order to further reduce the cost and reduce the number of parts, the primary pulverization refining member 4 is joined to the final pulverizing refining member 9 and the secondary pulverizing refining member 5 is clamped and fixed.
