It can be understood that by controlling the intake valve, the gas can be injected into the liquid storage chamber of the combiner's body. The pressure of the body of the moth is forced to flow through the body pipette, and then the liquid flow path of the four-way pipe is sent to the tee_tube for delivery to t or It is a real container. The process of taking out the liquid will not be in contact with the outside atmosphere to avoid contamination of the liquid. The clearing of the liquid allows the liquid from the container to be transported to the operation or the experimental device via the drain tube, and the gas can also be used. Introduce a drain pipe to discharge the miscellaneous force of the drain pipe, and provide a self-cleaning circuit. Other functions and embodiments of this creation are described below with reference to the drawings. [Embodiment] An embodiment of a liquid extracting device is constructed as shown in the "figure diagram", and includes: a four-way pipe 10 having a total of four joints, a first pipe joint u, a second pipe joint 12, and a third pipe joint 13 And a fourth pipe joint 14 having a gas flow path A and a liquid flow path L isolated from each other inside the four-way pipe 10, wherein the first pipe joint U is connected to a gas source s, and the gas source s can supply a gas having pressure. The gas may be a general compressed air or a compressed inert gas (such as nitrogen). It is preferred to use an inert gas if necessary to avoid reaction with the liquid stored inside the container 30 or to contaminate the liquid; the sealing cover 20' can be sealed. The opening 31 of the container 30, the sealing cover 20 has a gas injection pipe 21, and one end of the gas injection pipe 21 is connected with the gas flow path A of the four-way pipe 1'. The other end of the gas injection pipe 21 projects into the liquid storage chamber top end 32 of the container 30 (see "Fig. 4"), the gas can be injected into the reservoir of the container 30; one end of the liquid pipette 40 extends through the sealing cap 20 into the bottom end 33 of the reservoir 30 of the container 30 (see "Fig. 4"), and the other end Connected to the liquid flow path L of the four-way pipe, The liquid entering the liquid suction pipe 4〇 is guided to the outlet of the liquid flow path L of the four-way pipe 10 (ie, the second pipe joint 12 in the figure); M418976 intake valve 50, the inlet end 51 is connected to the gas source S, the outlet The end 52 is connected to the gas flow path A of the four-way pipe 10, the rib or the connection of the _four-way #1(), the connection port of the source § and the three-way valve 6〇, having the outlet 63 and the first inlet 61 Connected to the second inlet 62, the outlet 63 is connected with a drain pipe 64'--input ί6ί connected gas source s, and the second inlet (7) is connected to the outlet σ of the liquid-jet flow path L of the Teeguanchuan (ie, the second pipe joint 12) The outlet 63 may be selectively connected to the first inlet 61 or the outlet 63 and the second inlet 62 may be selectively controlled by a user. "Fig. 2" is an embodiment of the four-way pipe 1 (but not the only one). From the figure, the gas from the intake valve 5〇 can be seen from the first pipe joint of the four-way pipe 1G. u enters the gas flow path A, and then enters the gas injection pipe 21 from the fourth pipe joint 14 downstream of the gas flow path a, and the liquid flow path L is the inner diameter and the liquid of the second pipe joint 12 of the four-way pipe 1 () The smear of the straw squad together constitutes 'specifically, a small section of the liquid suction pipe 40 extends from the center of the gas injection pipe 21 into the four-way pipe ίο, after passing through the fourth pipe joint 14 and the second pipe in the same axial direction The inner diameters of the joints 12 are joined together 'by isolating the gas flow path A from the liquid flow path L, in other words, the first pipe joint u, the third pipe joint 13 and the pipe _ 14 are in communication with each other in the pipe 1G _ This structural arrangement allows the gas injection pipe 21 and the liquid suction pipe 4 to form a double-tube structure that passes through the sealing cover 2 and coaxially without the need to provide a separate liquid supply for the sealing cover 2 The position where the straw 4 passes. In the present invention, the gas injection pipe 21 passes through the sealing cover 2, the sealing cover 2 and the gas injection pipe are made of metal, and the material pipe 2 and the sealing cover are closely adhered to each other. High air pressure, if the gas source s rail a is within the range that other materials such as plastic can withstand, it is even possible to use the material to make the sealing cover 2; an embodiment of the sealing cover 2 〇 M418976 has a thread 22, There is also an axially extending cutting wall 201 on the outside of the sealing cover 20 for screwing the thread 22 and the opening 31 of the container 30, for example, with a movable wrench or other suitable tool. The position where the end face of the opening 31 is in contact with the opening 31 may be provided with a sealing collar 23 to increase the airtightness between the sealing cover 2G and the opening 31. If the opening of the container 30 is not threaded, the sealing cover 2 can be changed according to the actual condition, or other suitable components (such as the «ring) cover 2G can be tightly clamped to the (4) (four) port 31, which is familiar to the user. .-Technology lying with the usual knowledge should be changed and implemented according to the above description of this creation. This creation (4) - actual compensation, also has a pressure gauge warfare "3rd map" connected to the quiz #1 (), the pressure gauge 7G can be connected to the third pipe joint 13 of the pipe 1Q and The gas flow path A communicates with each other to display the pressure inside the vessel 3, thereby controlling the connection between the gas inlet A and the gas source s of the four-way pipe 10. The operation mode of this creation is as follows: When the normal state is not in use, the intake valve 50 is in the closed position, and the connection between the gas flow path A of the four-way pipe 1 and the gas source S is cut off (see "Fig. 2"). ), the 6-way tee is also located at the closed position. As shown in the equivalent structural sectional view of "Fig. 4A", the outlet 63 and the first inlet 61 are not connected, and the outlet 63 and the second inlet 62 are not connection. To take the liquid out of the H 30, first open the _ 5 () (as the case can adjust the opening), at this time the surface of the seam surface s (four) gas flow path A and the domain tube U into the combiner 30 The liquid storage chamber then switches the three-way valve 6〇 to the liquid discharge position of the “Fig. 4”. At this time, the outlet 63 and the second inlet 62 are connected, and the liquid is forced into the liquid suction pipe 4 by the gas, and then passes through the four-way pipe. The liquid flow path L of 10 goes to the second inlet 02 of the three-way valve 6〇, and is then guided to the working or experimental container 8 via the outlet 63 and the draining officer 64. After taking out enough liquid, 7 M418976 will be closed according to the intake valve 50 and the three-way valve 60. The creation also has a self-cleaning circuit, which can be used to force the residual liquid in the drain pipe 64 to be discharged. These residual liquids are exposed to the atmosphere and can be contaminated not only by harmful organisms, but also if they are not removed. When self-cleaning, the three-way valve 60 can be directly switched to the cleaning position as shown in the "4C" diagram. This _th-population 61 and π 63 are connected, and the compressed gas of the gas source s can be cited. The human drain tube 64' forces the residual (four) (four) to be discharged, achieving self-cleaning and reducing liquid residue. Although the present invention has been disclosed above through the above embodiments, it is not intended to limit the creation of this novel. Any "image-like artist" Lin is out of the spirit and scope of this creation, and can make some changes and refinements. It is subject to the definition of the request for the book of the county.
