乳液泵-般是安裝在容器的開口處，用於藉由 料動按壓操作將容器内的諸如乳液^ Γ供使用。目前，市場上已存在多種乳液泵防進2 構，用於防止水之類的外界液體在乳液系操作過 系而進入容器污染容器内所裝産品。然而，這些傳統二方 進，機構多少都存在難以杜絕外界液體進入容器内部的 問題。 例如，中國專利公告CN23141 28Y提出了一種乳液泵 防進水機構。如圖6和7所示，這種傳統的乳液栗防進水 機構基本由壓頭11 0、汽叙蓋1 20和連接導管1 3〇構成。 壓頭110内形成有一通冑ln，通道下端開口由一從壓頭 _丑直向下延伸的管接頭112限定。壓頭11〇圍燒管接 頭Π2還形成有一鎖定管113，該鎖定管在其上部的外壁 _开^成有外螺紋。連接導管130的上端131壓配合於壓 頭110的官接頭112内，從而與壓頭110固定連接，並使 連接導官130的内部與壓頭的通道ηι流體連通。汽缸蓋 120的中央有一供連接導管13〇通過的中央通孔121，在 中央通孔的下部内壁面上設有一豎直向上延伸超過汽缸 5 1314121 ΐ 120上平面的防進水導向套管122,防進水導向套管的 :壁面與連接導管13〇的外壁面滑動配合，防進水 =2的外壁面與中央通孔121的上部内壁面之間形成一 供壓頭的鎖定；越 s 113擰入的環形凹陷124。在中央通孔121 的”防進水導向套τ ! 22外壁面相對的内壁面上形成有 内螺紋’當壓帛110被壓下而使鎖定管ιΐ3的下端進入環 形凹P“ 24並加以轉動時’該内螺紋能與鎖定管⑴上的 外螺紋喷合而使壓頭11Q相對於汽叙蓋i2Q鎖定。 在對具有上述乳液泵防進水機構的乳液泵進行按壓 栗送操作時，壓頭110從其相對於汽缸蓋12〇的按壓行程 上止點位置開始被向下壓，直到鎖定f丨丨3的下端邊緣進 入汽缸蓋120的中央通孔121内壁面與防進水導向套管 12 2外壁面之間的環形凹陷i 2 4並且鎖定管上的外螺紋的 最下側螺牙與中央通孔121上的内螺紋的最上側螺牙相 抵靠，該螺牙相抵靠的位置即爲壓頭n〇相對於汽缸蓋 120的按壓行程下止點位置。在壓頭11〇從按壓行程上止 點位置被壓到按壓行程下止點位置的過程中，容器（未圖 示）内的液體被泵送出，與此同時，外界空氣通過防進水 導向套管122内壁面與連接導管130外壁面之間的微小間 隙被吸入容器内部，以補償容器内因液體體積的減小造成 的負壓。但是，當壓頭丨丨〇被下壓到其鎖定營丨丨3下端進 入汽缸蓋120的環形凹陷124時，如果該環形凹陷124内 積存有污水或其他液體（該積存液體在諸如浴室之類的潮 濕場合通常是無法避免的），則鎖定管丨丨3下端將浸入該 6 1314121 積存液體中而阻斷容器内部與外界大氣的連通，這樣’壓 頭110的繼續下壓會造成該積存液體被吸入容器内部，導 致容器内的液體産品被污染。The lotion pump is generally mounted at the opening of the container for use in a container such as an emulsion by a feed press operation. At present, there are a variety of emulsion pump prevention structures on the market for preventing external liquids such as water from operating in the emulsion system and entering the products contained in the container contamination container. However, these traditional two-way, institutions have some problems that are difficult to prevent outside liquid from entering the interior of the container. For example, Chinese Patent Publication CN23141 28Y proposes an anti-intake mechanism for a lotion pump. As shown in Figures 6 and 7, the conventional lotion-resistant water inlet mechanism basically consists of a ram 11 0, a steam cover 1 20 and a connecting pipe 13 〇. A through ln is formed in the ram 110, and the lower end opening of the passage is defined by a pipe joint 112 extending downward from the ram. The indenter 11 is also formed with a locking tube 113 which is externally threaded on the outer wall of the upper portion thereof. The upper end 131 of the connecting conduit 130 is press fit into the gland 112 of the ram 110 to be fixedly coupled to the ram 110 and to provide fluid communication between the interior of the connecting guide 130 and the passage η of the ram. The central portion of the cylinder head 120 has a central through hole 121 through which the connecting duct 13 passes. On the lower inner wall surface of the central through hole, a water-proof guiding sleeve 122 extending vertically upward beyond the upper surface of the cylinder 5 1314121 ΐ 120 is provided. The water guiding sleeve has a wall surface which is slidably engaged with the outer wall surface of the connecting duct 13〇, and an outer wall surface of the water intrusion prevention=2 and the upper inner wall surface of the central through hole 121 form a locking for the pressure head; the more the s 113 is screwed in Annular recess 124. An internal thread is formed on the opposite inner wall surface of the "intake prevention guide sleeve τ ! 22 of the central through hole 121" when the pressure pin 110 is depressed so that the lower end of the lock tube ι 3 enters the annular recess P 24 and is rotated. 'The internal thread can be sprayed with the external thread on the locking tube (1) to lock the ram 11Q with respect to the steam cap i2Q. When the emulsion pump having the above-described emulsion pump anti-intake mechanism is pressed, the ram 110 is pressed downward from its pressing stroke top dead center position with respect to the cylinder head 12 , until the lock f 丨丨 3 The lower end edge enters the annular recess i 2 4 between the inner wall surface of the central through hole 121 of the cylinder head 120 and the outer wall surface of the water inlet preventing sleeve 12 2 and the lowermost thread and the central through hole 121 of the external thread on the locking tube The uppermost thread of the internal thread abuts, and the position at which the screw abuts is the bottom end position of the pressing head n〇 with respect to the cylinder head 120. During the pressing of the ram 11 〇 from the pressing stroke top dead center position to the pressing stroke bottom dead center position, the liquid in the container (not shown) is pumped out, and at the same time, the outside air is guided through the water prevention. A slight gap between the inner wall surface of the sleeve 122 and the outer wall surface of the connecting duct 130 is drawn into the interior of the container to compensate for the negative pressure in the container due to the decrease in the volume of the liquid. However, when the indenter is pressed down to the lower end of the lock camp 3 to enter the annular recess 124 of the cylinder head 120, if the annular recess 124 contains sewage or other liquid (the accumulated liquid is in a bathroom or the like) The wet condition is usually unavoidable, and the lower end of the locking tube 3 will be immersed in the 6 1314121 accumulating liquid to block the communication between the inside of the container and the outside atmosphere, so that the continued pressing of the indenter 110 will cause the accumulated liquid to be accumulated. It is sucked into the interior of the container, causing contamination of the liquid product in the container.

The main object of the present invention is to provide an emulsion pump anti-water inlet mechanism that minimizes the ingress of external liquids. In order to achieve the above object of the present invention, in accordance with one aspect of the present invention, an emulsion pump water prevention mechanism is provided, comprising: a pressing head having a passage formed therein, and a periphery of the opening of the lower end of the passage is formed with a body from the head of the indenter a locking tube extending straight downwardly, the locking tube is formed with an external screw on the outer wall surface thereof, and is connected to the guide camp, and the upper end of the connecting duct is fixedly connected to the opening at the lower end of the passage of the pressure head to communicate with the pressure head passage; The cylinder head has a through hole at the center of the cylinder head for the passage of the connecting duct, and is provided on the lower inner wall surface of the central through hole - an anti-intake guiding sleeve extending vertically upward beyond the upper surface of the cylinder head, and the water guiding guiding sleeve A sliding fit is provided between the inner wall surface and the outer wall surface of the connecting duct, and the gap provides (four) communication between the inside of a container in which the emulsion pump is installed and the outside atmosphere, and the outer wall surface of the water guiding guiding sleeve and the central passage are An annular recessed portion is formed between the upper inner wall surface of the hole for locking into the outer wall surface of the central through hole opposite to the water inlet guiding sleeve::: upper: capable of locking The external thread on the tube is combined to make the indenter lock with respect to the A red snail, and the -h shovel has a dead center position relative to the steam cover and a dust stroke bottom dead center position, the pressing 7 1314121 The position of the point is defined as a position of the indenter when the external thread pressed down onto the locking tube abuts against the internal thread on the central through hole of the cylinder head, and at least one of the locking s is formed from the lower end edge of the locking tube along the locking tube JL· -- . ' ^ Partially extended slit, the upper end of which is arranged to be higher than the upper plane of the cylinder head when the pressure head is in the lower end position of the pressing stroke with respect to the steam red cover. Incidentally, "upper" and "lower" as used herein are defined for the orientation of the lotion pump in normal use (i.e., the emulsion pump is arranged such that its longitudinal axis extends in the vertical direction). With the emulsion pump anti-water inlet mechanism of the present invention, since at least one slit extending from the lower end edge of the locking tube to the length of the locking tube to the length of the trowel is formed on the locking tube, and the upper end of the slit is disposed at The cylinder head of the indenter phase is higher than the upper plane of the cylinder head when the pressing stroke is at the bottom dead center position. Therefore, even if the pressing head is pressed down, the lower end of the locking tube is immersed in the sewage accumulated in the annular recess of the cylinder head, and the locking tube is The incision can always be confirmed and protected. [5] Direct communication with the outside atmosphere, so as to prevent the accumulated water in the annular recess of the cylinder head from being sucked into the interior of the container to contaminate the liquid product. Moreover, the incision is from the lower end of the lock tube. Starting to extend, it# makes the incision into an open area (rather than a closed area such as a circular hole), thereby helping to prevent the adsorption of liquid due to surface tension and its He stuck in solid impurities. The above-mentioned incision can be advocated.. , _ ^ stiff 3 is set to strip, or two or more strips can be set. The incision can be thin and also ^, c, , · long The shape of the 'distal and elongated shape is beneficial to prevent the liquid (especially the septic liquid) from clogging the incision due to the surface tension from the m ^ ^ - clothing tension, and preventing the impurities other than the body 8 1314121' from blocking the incision. JU oj day rectangle, which can also be unequal width = uniform width, in addition, the slit can extend along the longitudinal axis of the locking tube: ', his irregular shape. Line), or slightly deviate from the longitudinal That is, the longitudinal axis of the lotion pump is also inclined to extend in order to achieve the upper side of the present invention. Aspect & a seedling liquid pump anti-intake mechanism... a channel is formed in the other end, under the channel. a locking tube extending straight downward is formed with an external thread from the roof; a connecting duct is formed on the wall surface thereof, and the upper jaw is fixedly connected to the opening of the opening I of the indenter, thereby Connected to the indenter channel, · — For connecting the pipe through/redness, & rainbow cover ^ hole in the lower inner wall of the central through hole, the sigh has a vertical upward extension, the anti-inlet water guiding sleeve on the upper surface of the cylinder, preventing the water from guiding the meat of the camp There is a gap between the inner wall surface of the plug and the outer wall surface of the connecting duct, and the gap between the inner wall and the outer atmosphere is provided by the gap between the inside and the outside atmosphere. Forming a lock between the upper inner wall surface of the hole; the garment is concave, and is formed on the inner wall surface of the central through hole and the water inlet guide sleeve pair to be slidable with the external thread on the lock tube : the internal thread of the head relative to the cylinder bore, wherein the indenter presses the C stroke top dead center position and the pressing stroke bottom dead center position with respect to the cylinder head - the β' T private bottom dead center position is defined as the indenter When being pressed down to the position where the locking pipe thread is against the internal thread on the central through hole of the eight-cylinder cover, the external thread of the lock cylinder is spirally extended upward from the lower end edge of the locking pipe, and, ^^ > The internal thread on the central through hole of the cylinder head is from the central through hole The lower end edge 9 1314121's lower:: screw % extension 'so that only the rotation of the locking tube, the edge into the cylinder head annular recess, while in the indenter; j:gyt cover is in the pressing rod 鼗T, Mibans The ridge head is recessed in the annular shape with respect to the cylinder. The bottom end position of the I-locking pipe does not enter the outer screw, and the water mechanism 'because the center of the cylinder head on the locking pipe is open, the edge begins to spiral upward, and the downward spiral of the steam starts from the central m-end edge. The sample will press the pressure head relative to the cylinder head 彳fg into the dust-pressing action without causing the lower end of the locking tube to enter or become apparent, even if the steam has "two == medium." The pressing action T is a compensation for the night body. Since the locking tube enters the cylinder head annular recess inside and outside the lock tube, the tolerance can be avoided. : And, in the case of being blocked by the accumulated water in the annular recess of the cylinder head, (4) even if the liquid is filled in the annular recess of the steam red cover and the 盍 & shaped recess is locked due to the phase difference between the threaded threads or the like. In the extreme case, because the upper level of the cylinder head is larger than the upper limit of the cylinder head, the upper end of the sleeve can also be prevented from being high. Therefore, the suction of the liquid is stopped. The external thread on the lock S and the internal thread on the nipple in the cylinder head can be saved in the form of the central hole of the TM A cylinder head or other multi-threaded threads. It can also be double-ended. Other features and advantages of the water intake prevention mechanism will be described below with reference to the description of the exemplary embodiments. 10 1314121 ' [Embodiment] Referring to FIG. 1 - 3 'The emulsion pump anti-intake mechanism of the present invention is combined with a conventional type of emulsion pump for mounting on an opening of a container (not shown) Pumping the product in the container. The emulsion pump water prevention mechanism generally includes a pressure head 10, a connection conduit 30 fixedly coupled to the lower portion of the pressure head 1b, and a cylinder head 20 having a central through hole through which the connection conduit 3 is passed. The above-mentioned indenter 10, connecting pipe 3〇 and cylinder head 2〇 and other components (as shown in the figure, their structure and their cooperation with the member of the present invention belong to the prior art) constitute a lotion, but due to the present invention The water-repellent pump anti-intake mechanism basically only involves these three components, so this article does not describe other components. In Figs. 1 and 2, the head 10 is in the private stop position with respect to the cylinder head 2, and in Fig. 3, the head 1 is in the locked position. Referring now to Figures 4A-4D, the indenter 10 is formed with a portion including a horizontal extension of the passage L and a portion extending from the horizontal extension: a lower portion, a lower end of the vertically extending portion of the passage 11. a η The pipe joint 12 extending from the main body of the ram 10 and extending straight downward defines a sweat port formed by a lock joint 13 around the pipe joint 12, and the lock J ram 12 is a coaxial 'pipe joint 12 and a lock pipe ΐ 3 The second axis of the official joint emulsion pump. The inner wall surface of the pipe joint 12 is a flat ring #16, and the four ring-shaped pipe joints formed by the joint conduits formed with two water ribs 33 (described later) are formed by (4). 〗2. The pipe joint 12 and the locking pipe 13 are two; /: the fixed connection is formed into a ring 11.1314121 The gap 17 is inserted into the water-proof guide bushing 22 (described later) on the steam cover 20. The outer wall surface of the pipe joint 12 (or the outer wall surface of the connecting pipe or the inner surface of the locking pipe) is formed with a horizontal annular projection 18 which is disposed on the pipe joint 12 so as to be pressed down to the locking pipe by the pressing head. When the lower end edge of the 13 reaches the position of the upper surface 25 of the cylinder head 20, the annular projection 18 has been radially engaged with the upper end portion of the water prevention guide sleeve 22, thereby blocking fluid communication inside and outside the container.

The locking member 13 is formed on its outer wall surface with an external thread 14 which spirally extends from the lower end edge of the locking tube 13 over the entire outer wall surface of the locking tube. The reduced ^ 5 ' connection guide f 3G has a body portion 32 and a diameter terminal 31 for coaxially press-fitting the tubular rib 2 of the ram 10 . The outer wall surface of the upper end of the connecting duct 30 is formed with a net on the two annular surfaces. At the upper end, the tube joint 12 is coupled with the inner wall 12 of the pipe joint, that is, the press 16, so that the connecting pipe and the pipe are connected. The passage of the joint head is fixedly connected and the interior of the connecting conduit 30 is in fluid communication with the press fitting 1 . The outer diameter of the connecting duct main body portion 32 is the same as that of the pipe head 12, so that the connecting duct 30 is fixedly connected to the pipe joint, and is formed into a continuous outer wall surface. 21, in the center of the middle 2, there is a central through hole through which the connecting duct 3〇 extends beyond the lower inner wall surface of the steam hole, and is integrally provided with an upper plane 25, that is, a central through hole Upper end 12 1314121 • Edge-proof water guiding guide sleeve 22. The water-proof guiding sleeve core is continuously connected with the connecting conduit main body portion 32 and the tube soil head i 2, and the movement is matched, and at the same time, there is a slight gap between the two mating surfaces. An internal space between the inside of the exchanger and the outside atmosphere is provided. When the lower end edge of the indenter 10 "3" is pressed down to the position of the upper plane 25 of the cylinder head 2 (i.e., the upper end edge of the central through hole 21), that is, the water inlet guide sleeve 22 is just inserted into the pipe joint 12 and locked. When the annular gap 17 between the tubes 13 is formed, the inner wall surface of the upper end portion of the water inlet preventing sleeve 22 is sealed in a radial tight contact with the annular projection 18 on the pipe joint 12, thereby blocking the air communication passage. An annular recess 24 into which the locking tube 13 of the ink supply head 10 is dropped is formed between the outer wall surface of the inlet guide sleeve 22 and the upper inner wall surface of the central through hole (4). The outer wall of the central through hole 21 and the water inlet guide sleeve 22 Opposite: an internal thread 26 is formed on the inner wall surface, and when the lower end of the locking tube 13 is pressed into the annular recess 24 and rotated, the internal thread = can be engaged with the external thread 14 on the locking tube 13 The ram 1 is locked with respect to the cylinder head 20. The internal thread 26 extends spirally from the upper end edge 2 of the central through hole 21 to the vicinity of the bottom of the annular recess 24 so that the locking tube can be screwed into the annular recess 24 as a whole. The radial dimension of the annular recess 24 The thickness of the lock tube 13 is substantially the same so that the inner wall surface of the lock tube 13 is prevented when the external thread 14 on the outer surface of the lock tube 13 is engaged with the inner surface 26 of the inner wall surface of the cylinder head central through hole 21. The outer wall surface of the inlet guide sleeve is in contact with each other, so that the locking of the locking tube 3 in the annular recess 24 is more stable, and the sliding of the sliding teeth 33 1314121 caused by the radial clearance is prevented. Threaded cymbal and cylinder head 2. The internal thread 26 on the central through hole 21 is slewing, and the number of threads on the upper and lower threads of the squirrel and the squirrel are in the thread. Thus, it is possible that: 相位 phase usually differs by 180 degrees, and the screw is abutted, thereby reducing the position of the diametrical direction relative to each other to provide access to the annular recess 24: the lock caused by the difference 13" slightly produces 歪钭 and guide & Spit and prevent the locking tube 13 from being skewed by the pressing force and causing an undesirable thread jam. The q, Guangshi.a of the present invention will be described below with reference to Japanese, Japanese, and the accompanying drawings. ^ Month's role of the fruit liquid prevention water inlet mechanism = the head 1〇 is pressed down to the two end edges shown in the figure 抵 against the central through hole 汽缸 of the cylinder head 2〇:::: At this time, due to the locking tube The thread of the external thread u on the 13 is: at the side, the thread from the upper end edge to the hole 1TM (7) is in the middle, so that the screw on the locking camp z, the central through hole 21 abuts and is blocked. The screw dent... The state at the moment is the indenter 丨 2 1 into the shape: line: bottom dead center position. In this way, even if the ring 2:2:: presses, the head 1G is no longer going down, and the q will send => 1 1 The pumping water caused by the pump pressure is sucked into the container and the outer wall surface It is also auxiliaryly formed with a ring shape and 'because the lower end edge of the pipe joint 13 is pressed down to reach the steam cover 18'. When the annular projection 18 has been positioned with the water inlet preventing surface 25, the wall surface is joined to form a seal, so that 1 is made. The inner end of the upper end portion is filled with 1314121 liquid in the ¥-shaped recess 24 and the locking tube 13 slightly enters the extreme end of the annular recess 24 due to the phase difference between the central through hole 21 and the inner and outer threaded threads of the locking tube 3 In this case, the seal formed by the annular projection 18 and the inner wall surface of the upper end portion of the water inlet preventing sleeve 22 can also prevent the accumulated liquid from being drawn into the container. § When the ram 10 is in the bottom position of the pressing stroke with respect to the cylinder head 2 ,, if the ram 10 is to continue to sag relative to the cylinder head 2, only the ram 10 is rotated relative to the cylinder head 2 , the external thread 14 on the locking tube 13 is engaged with the internal thread 26 of the cylinder φ 4, '£ - ΖΪ 1 toilet · central through hole 21, even if the locking tube 13 is screwed into the cylinder head 2 The annular recess 24 is. During the screwing process, the annular projection 18 on the head pipe joint 12 is always in close engagement with the inner wall surface of the cylinder head 20 against the water inlet guide π 22 until the external thread 14 of the locking tube and the internal thread on the central through hole 21 26 completely slams the lock position of Fig. 3, thereby cutting off the air communication passage. Also, it is said that the annular projection 18 on the pipe joint 12 starts from the bottom end position of the pressing stroke of the indenter 1〇, and the position of the inner wall of the anti-inflow guide sleeve 22 is always kept in engagement with the inner wall of the anti-intake guide sleeve 22. The foreign matter (including the accumulated liquid in the annular recess 24) is prevented from being drawn into the container during the process of the locking tube 13 being screwed into the ring ～24. When the outer thread M 14 and the thread 14 are fully engaged with the internal thread 26, the crown 1 is locked with respect to the cylinder head 20, as shown in Fig. 3, the lock H is stored and transported. Use ^. In addition, due to the fact that the entire length of the locking tube along the locking tube is formed on the θ + extending in the locking twist 〗 q ^ b ' even during the pressing process, the longitudinal slit κ of the head 10 is accumulated in the annular recess 24 of the cylinder head. The liquid, which can provide air 15 1314121 ί between the internal and external atmosphere, allows the outside air to compensate the negative pressure in the container caused by the pressure operation through the vertical portion, thereby effectively preventing the ring The accumulated liquid in the recess 24 is sucked into the interior of the container to cause contamination. In the above-mentioned exemplary practical 彳丨+, +., in the embodiment, in part for the purpose of simplification and return, the technical solutions of the above two aspects of the present invention are in the same-milk: fruit-proof water The implementation is carried out in the organization's, but those skilled in the art can understand that the two technical solutions can be implemented independently and achieve the purpose respectively. Of course, those skilled in the art will also understand that this will be a significant effect. It will be apparent to those skilled in the art that various changes can be made to the above-described embodiments by the use of the present invention. For example, in the above embodiment, the second step: extending from the lower end edge of the locking tube 13 over its entire length 妒 can be changed to make the slit open from the lower end edge of the locking tube over its partial length as long as The upper end of the slit is _ by / P on the cylinder head when the ram plane cover 2 is at the lower end position of the pressing stroke. For example, in the above embodiment, the connecting duct 30 is fixedly connected to the indenter 10 by being inserted into the joint 12 of the head 1 , and the solid: the remote joint can be replaced by the connecting duct 3 The pipe joint 12 is connected to the dust head = or the connecting pipe 3Q is directly fixed to the joint 12 of the joint 12 . In the connection duct 3G, the sleeve is fixedly connected to the dust head 1〇 or the pipe joint 12 is not used and is directly placed on the connection guide: the underside T protrusion 18 can of course be set 30. For example, in the above In the embodiment, the annular projection 16 • 1314121 18 is disposed on the outer wall surface of the pipe joint 12 to be radially engaged with the inner wall surface of the water prevention guide bushing 22, but the annular protrusion 8 may also be set in the lock. The inner wall surface of the tube 3 is radially joined to the outer wall surface of the water-proof guide sleeve 22. (4), the self-change described above may affect the implementation of the present invention and the object of the invention. Therefore, the present invention The scope of protection is not limited to the specific embodiments described, but should be reasonably limited by the scope of the patent application.
