Moreover, the first inner chamber 133a has a socket 135a adjacent to the first end surface 13u, and the sleeve 132 is slidably connected to the mouth I22 of the accommodating bottle no through the socket 135a. On the other hand, the flow guiding column 134 is located in the first inner cavity 133a and extends from the second end surface 131b toward the first end surface 131a. Moreover, the flow guide column 134 includes a body 136 and a splash guard 138. The body 136 is coupled between the sleeve 132 and the splash guard 138, and the body 136 is retracted relative to the splash cone 138. It is worth mentioning that the skilled person can determine the ratio of the diameter D of the bottle opening 122 to the length l of the guiding rod according to actual needs, and the Di/l of the embodiment is about 0.5 ', but the invention does not Limited to this, it can be adjusted according to actual needs. The guide column 134 can be integrally formed with the sleeve 132. The guide column 134 can be detachably assembled in the first inner cavity 133a of the sleeve 132 to facilitate disassembly and cleaning. . As shown in FIG. j, the first inner cavity 133a of the sleeve n may have an opening adjacent to the second end surface 131b, and the body 136 of the guide column may include an abutting portion 136a, and the abutting portion 13 is extended. The second end face (10) of the sleeve 132 is received outside the opening 135b. That is, the guide post 134 can be assembled to the sleeve 132 by the abutting portion 136a of the body 136. Further, the bearing 4 136a may be annular and have an outer diameter D2 larger than the aperture Da' of the opening 135b so as to be received against the second end face 13. In addition, in another embodiment of the present invention, the guide bar 134 can be assembled to the sleeve 132 by screwing with a thread 1375588 T and a thread on the sleeve 132 (not shown), as shown in FIG. As shown in FIG. 2C, the flow guide column 134 can be located within the first inner cavity 133a and screwed to the opening 135b. However, the present invention is not limited thereto, and those skilled in the art will appreciate that the 'flow guide post 134' may also be assembled in the first inner chamber i33a of the sleeve 132 in other manners.
請再次參照圖1，導流柱134之本體136可具有至少一個 流道137、第二内腔133b以及排氣口 139，其中第二内腔13北 位於本體136的中央，且排氣口 13.9是鄰近套座132之第二端 面131b，並且暴露出第二内腔133b。換言之，第二内腔 是藉由排氣口 139而連通至外界。另外，值得一提的是，在圖 2A至圖2C所示之實施射，導流柱134可以螺鎖的方式組裝 於套座132上，且本體136的排氣口 139之截面積例如是呈六 角狀，因此在將導流柱B4組裝於套座132上時，即可利用六 角扳手***排氣口 139轉動，以帶動導流柱134藉由螺紋^ 轉入套座132的第一内腔133a。 請繼續參照®卜流道137是連通第一内腔133a虚第二 内腔133b。其中，流道137可較佳地在朝向第二内腔腿的 方向往防濺賴138傾斜，以使因脫泡而賴至本體136外壁 的液體較易流人至第二内腔133b。防濺錐體138則且有頂面 138a與錐面138b，其中頂面⑽連接於錐自隱與本體 之間’錐® 138b則是自防錢錐體138兩側往防濺錐體138之 中央朝向容納槪120的瓶口 122傾斜。 m ^ ^ 接在容納瓶12G的瓶口 122，且容納瓶 於真空腔室UG内之後，液體1G1 _氣體會經由 ^道137與第二腔室】33b，而從排氣口】39 外。在這期間，即使液體101隨著氣體的逸出而朝往 8 上濺’則可藉由錐面138b減少液體濺出容納瓶120外。而且， 由於錐面138b是自防濺錐體138兩側往中央朝向容納瓶120 =瓶口 122傾斜，因此可令往上濺出瓶口 122的液體ι〇1再順 著錐面138b流回容納瓶120内。 值得一提的是’為使在脫泡過程中往上濺的多數液體1〇1 均能流回容納瓶12〇内且能兼顧真空脫泡時的排氣順利，需將 防濺錐體138之頂面138a與錐面138b的交接處與套座132之 間的間隙d控制在適當的範圍内，以避免液體1〇1濺到防濺錐 體138上方而無法順著錐面138b流回容納瓶12〇内或脫泡效 果不佳。在此，由於瓶口 122之口徑Dl愈大的容納瓶12〇會 使用體積愈大的防濺錐體138來阻擋濺起之液體1〇1流入第二 内腔133b’以避免滅起的液體1〇1易於流入第二内腔η%内。 而防濺錐體138愈大，液體要進入第二内腔133b之前所經之 路控要更長’因此，即使間隙d隨著瓶口讀D]而增大，仍 可維持同樣果。具體來說，本實施例是將_⑽瓶口口 徑D!的比值d/D,控制在〇·3%〜2.3%之間。以本實施例來說， 間隙d約為〇.2釐米，可視實際需求調整。 特別的是，本實施例之頂面138a例如是在遠離本體136 的方向上朝套座132的套接口 135a傾斜，因此即使液體1〇1 通過間隙〇!_防_體138上方，也可順著頂面ma再次 通過間隙d而流回容納瓶12〇内。 由上述實施例可知，防濺裝置130不但可以防止液體ι〇ι 在脫泡過程中由容納瓶12G的瓶σ 122賤出，更可以使滅起之 液體101流回容納瓶120内，以降低成本損失。 圖3為本發明之另一實施例中防濺裝置套 的示意圖。請參照圖3，防濺裝置23〇與前述防賤裝置13〇相 1375588 較之下’其導流柱234的本體236在鄰近防濺錐體138之頂面 138a之處更設置有回收流道237，以連通第一内腔n3a與第 二内腔133b。而且，回收流道237是在遠離第二内腔133b的Referring again to FIG. 1, the body 136 of the flow guide column 134 can have at least one flow channel 137, a second inner cavity 133b, and an exhaust port 139, wherein the second inner cavity 13 is located north of the body 136, and the exhaust port 13.9 It is adjacent to the second end face 131b of the sleeve 132 and exposes the second inner cavity 133b. In other words, the second inner chamber is connected to the outside through the exhaust port 139. In addition, it is worth mentioning that, in the embodiment shown in FIG. 2A to FIG. 2C, the guide column 134 can be screwed into the sleeve 132, and the cross-sectional area of the exhaust port 139 of the body 136 is, for example, The hexagonal shape is used. Therefore, when the guide bar B4 is assembled on the sleeve 132, the hexagonal wrench can be inserted into the exhaust port 139 to rotate, so as to drive the guide column 134 to be screwed into the first cavity of the sleeve 132. 133a. Please continue to refer to the channel 137 which is connected to the first inner cavity 133a and the second inner cavity 133b. Wherein, the flow passage 137 is preferably inclined toward the splash guard 138 in the direction toward the second inner cavity leg, so that the liquid which depends on the outer wall of the body 136 due to defoaming is more likely to flow to the second inner chamber 133b. The splash cone 138 has a top surface 138a and a tapered surface 138b, wherein the top surface (10) is connected between the cone self-concealing and the body. The 'cone® 138b is from the two sides of the anti-money cone 138 to the splash cone 138. The center is inclined toward the mouth 122 of the housing 120. After the m ^ ^ is connected to the mouth 122 of the bottle 12G, and the bottle is accommodated in the vacuum chamber UG, the liquid 1G1_gas will pass through the channel 137 and the second chamber 33b, and from the exhaust port 39. During this period, even if the liquid 101 splashes toward the top 8 as the gas escapes, the liquid can be splashed out of the containing bottle 120 by the tapered surface 138b. Moreover, since the tapered surface 138b is inclined from the both sides of the splash guard 138 toward the center toward the receiving bottle 120 = the bottle opening 122, the liquid ι 1 which splashes the bottle opening 122 can flow back along the tapered surface 138b. The bottle 120 is housed. It is worth mentioning that 'in order to make the most of the liquid 1〇1 splashing up during the defoaming process can flow back into the holding bottle 12〇 and can balance the evacuation when the vacuum defoaming is smooth, the splash cone 138 is required. The gap d between the intersection of the top surface 138a and the tapered surface 138b and the sleeve 132 is controlled within an appropriate range to prevent the liquid 1〇1 from splashing over the splash cone 138 and failing to flow back along the tapered surface 138b. The bottle is contained within 12 inches or the defoaming effect is not good. Here, the larger the diameter D1 of the bottle opening 122, the larger the size of the splash cone 138 to block the splashed liquid 1〇1 from flowing into the second inner chamber 133b' to prevent the liquid from being extinguished. 1〇1 easily flows into the second lumen η%. The larger the splash guard 138, the longer the control of the liquid before it enters the second inner chamber 133b. Therefore, even if the gap d increases with the bottle mouth reading D], the same result can be maintained. Specifically, in this embodiment, the ratio d/D of the _(10) bottle mouth diameter D! is controlled to be between 3% and 2.3%. In the present embodiment, the gap d is about 〇2 cm, which can be adjusted according to actual needs. In particular, the top surface 138a of the present embodiment is inclined toward the socket 135a of the sleeve 132, for example, in a direction away from the body 136, so that even if the liquid 1〇1 passes over the gap _!_防_body 138, it can be shun The top surface ma again flows back into the receiving bottle 12 through the gap d. It can be seen from the above embodiment that the splash guard 130 can prevent the liquid ι〇ι from being detached from the bottle σ 122 of the accommodating bottle 12G during the defoaming process, and can further cause the extinguished liquid 101 to flow back into the accommodating bottle 120 to reduce Cost loss. Figure 3 is a schematic illustration of a splash guard sleeve in accordance with another embodiment of the present invention. Referring to FIG. 3, the splash guard 23 is disposed opposite the front of the anti-snag device 13 1 1375588. The body 236 of the guide 234 is further provided with a recovery flow path adjacent to the top surface 138a of the splash cone 138. 237, to connect the first inner cavity n3a and the second inner cavity 133b. Moreover, the recovery flow path 237 is away from the second inner cavity 133b.
方向上往套接口 135a傾斜。因此，即使在脫泡過程令，液體 從間隙d濺到防濺錐體138上方，並經由流道137流入第二腔 室133b，其仍可沿著第二腔室133b的内壁流入回收流道237 内，再順著防濺錐體138之頂面138a與錐面138b流回容納瓶 120内。也就是說，防濺裝置23〇不但可以防止液體在脫 /包過程中濺出容納瓶120，更可以避免濺起的液體1〇1積在第 二腔室133b内而導致脫泡後損失太多的液體1〇1。 一，4為本發明之另一實施例中防濺裝置套接於容納瓶上 的不意圖。請參照圖4 ’為避免在將盛裝有液體1〇1的容納瓶 120放置於真空腔室11()内之前，外界的微粒子或其他物質對 液體101造成污染，本實施例之防賤裝置3〇〇與前述實施例之 防減裝置230相較之下，還可以包括上蓋31〇，裂設於套座132 上，與第二端面131b之間具有排氣通道32〇。在本實施例中， 上盒310例如是透過固定元件33〇而裝設於 由固定元件330來娜上蓋31〇與套座132之第二端面= 成排氣通道320。在液體101的脫泡過程中， 氣口 139之後’即是經由排氣通道32〇逸出至防 的是，本發明並不限定上蓋31()肖套座132之間 的，疋方式，可依實際需求調整。如圖5所示，上蓋楊 或其他方式直接固定在套座132上。而且，上蓋 槽420 面的蓋合面412例如是具有至少一條溝 U於上盍⑽裝設於套座m上時作為魏通道。當 1375588. 然，在另一實施例中，如圖2A及圖2B所示，也可以是在套 座132的第二端面131b上形成至少一條溝槽51〇，以於上蓋（圖 中未示)裝設於套座132上時作為排氣通道。 綜上所述，本發明之液體脫泡設備包括防濺裝置，其可套 接在盛裝有待脫泡之液體的容納瓶之瓶口，以防止液體在脫泡 過程中濺出。而且，本發明之防濺裝置更可以進一步令濺起之 液體流回容納瓶中，以避免液體濺起後積在防濺裝置内。由此 可知，本發明不但可以省去後續清理所需耗費的成本，更可以 • 減少在脫泡過程中的液體損失量。 另外’本發明之防濺裝置還可以包括防止外界污染源進入 容納瓶内的上蓋，因而能夠有效地保持液體的潔淨度。 雖然本發明已以較佳實施例揭露如上，然其並非用以限定 本發明，任何熟習此技藝者，在不脫離本發明之精神和範圍 内，當可作些許之更動與潤飾，因此本發明之保護範圍當視後 附之申請專利範圍所界定者為準。 【圖式簡單說明】 _ 圖1為本發明之一實施例中液體脫泡設備的示意圖。 圖2A為本發明之另一實施例中液體脫泡設備的示意圖。 圖2B為圖2A之防濺裝置的上視示意圖。 圖2C為圖2A之導流柱的立體示意圖。 圖3為本發明之另一實施例中防濺裝置套接於容納瓶上 的示意圖。 圖4為本發明之另一實施例中防濺裴置套接於容納瓶上 的示意圖。 圖5為本發明之另一實施例中防濺裝置套接於容納瓶上 的示意圖。 1375588. 【主要元件符號說明】 " 100 :液體脫泡設備 101 :液體 110 :真空腔室 120 :容納瓶 122 :瓶口 130、230、300 :防濺裝置 131a :第一端面 Φ mb :第二端面 132 :套座 133a :第一内腔 133b :第二内腔 134、234 :導流柱 135a :套接口 135b :開口 136、236 :本體 136a :承抵部 • 137 :流道 138 :防濺錐體 138a :頂面 138b :錐面 139 :排氣口 237 :回從流道 310、410 :上蓋 320 :排氤通道 330 :固定元件 12 1375588 412 :蓋合面 420、510 :溝槽 L :長度 d :間隙 D! :口徑 D2 :外徑 D3 :孔徑The direction is inclined to the socket 135a.
