[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0037] The gas-liquid integrated stirring device 100 of the present application is applied to a test device to stir a sampled liquid to meet the needs of subsequent experimental analysis of the sampled liquid.

[0038] like Figure 1As shown, a gas-liquid integrated stirring device 100 provided in an embodiment of the present application includes a control rod 10 and a stirring assembly 20. A first hose (not shown) and a second hose (not shown) are movably installed in the control rod 10. The first hose is used to exhaust gas, and the second hose is used to pump out sampled liquid; the stirring assembly 20 is detachably installed on the control rod 10, and the stirring assembly 20 includes a first tube body 21, a second tube body 22 and a straight tube 23. The first tube body 21 can be plugged in with the first hose, and the second tube body 22 can be plugged in with the second hose. The straight tube 23 is fixedly mounted on the second tube body 22 so that a cavity is formed between the straight tube 23 and the second tube body 22 (not shown), and the first tube body 21 is fixedly connected to the straight tube 23 and communicates with the cavity. That is, when the gas-liquid integrated stirring device 100 is working, the second hose can discharge the sampled liquid into the test bottle (not shown) through the second tube body 22, and then the first hose can be used to discharge the gas into the sampled liquid through the first tube body 21 and the straight tube 23, and the sampled liquid can be stirred, and then the stirred sampled liquid can be drawn back by the second tube body 22. Here, the first tube body 21 and the second tube body 22 are both configured as stainless steel thin tubes, and the straight tube 23 is connected to the second tube body 22 by welding.

[0039] It can be understood that the gas-liquid integrated stirring device 100 integrates the extraction of sampling liquid and the external exhaust gas into one, which can simplify the structure of the gas-liquid integrated stirring device 100 and reduce costs; at the same time, since the stirring component 20 can be detachably mounted on the control rod 10, on the one hand, it is convenient to clean the stirring component 20, and on the other hand, the gas-liquid integrated stirring device 100 can be adapted to the stirring of different sampling liquids by replacing the stirring component 20, thereby achieving multiple uses of one item and further reducing costs.

[0040] like Figure 2 , Figure 3 As shown, the control rod 10 is provided with an eccentric waist groove 11; wherein, the second tube body 22 has a transverse tube portion 221, and the transverse tube portion 221 can be elastically deformed under the drive of an external force, and the deformed transverse tube portion 221 can be inserted into the eccentric waist groove 11 and plugged with the second hose. In other words, the stirring assembly 20 can utilize the elastic deformation of the second tube body 22 to realize the assembly on the control rod 10, which not only facilitates the assembly and disassembly of the stirring assembly 20 on the control rod 10 and facilitates the operation of the experimenter, but also simplifies the structure and has the effect of further reducing costs. Here, the above-mentioned eccentric waist groove 11 specifically refers to a waist-shaped hole eccentrically arranged relative to the center line of the control rod 10 on the control rod 10.

[0041] Specifically, the transverse tube portion 221 inserted into the eccentric waist groove 11 can abut against the groove wall 111 of the eccentric waist groove 11, and is used to limit the stirring assembly 20 to the control rod 10 in the vertical direction, and specifically realize the assembly limit of the stirring assembly 20 in the vertical direction of the control rod 10, thereby playing a role in the assembly of the stirring assembly 20 on the control rod 10.

[0042] As preferably, Figure 2 , Figure 3 As shown, the control rod 10 is provided with an arc groove 12 at the position where the groove wall 111 is located, and the transverse tube portion 221 can be inserted into the arc groove 12 and abut against the arc surface 121 of the arc groove 12. Here, the arc surface 121 is the groove wall of the arc groove 12. In this way, the limiting force of the transverse tube portion 221 when abutting against the groove wall 111 in the vertical direction can be increased, thereby further improving the stability of the stirring assembly 20 when assembled on the control rod 10 in the vertical direction.

[0043] like Figure 1 , Figure 4 As shown, the control rod 10 includes a bottom plate 13, and a circular hole 131 is provided on the bottom plate 13; wherein, the first tube body 21 has a vertical tube portion 211, and the vertical tube portion 211 can be plugged and matched with the circular hole 131, so as to limit the stirring assembly 20 to the control rod 10 in the circumferential direction. In other words, the stirring assembly 20 can utilize the plug-in match between the vertical tube portion 211 on the first tube body 21 and the circular hole 131 on the bottom plate 13 to realize the assembly limit of the stirring assembly 20 in the circumferential direction of the control rod 10, and meet the use requirements of the stirring assembly 20 being assembled on the control rod 10. Here, a waist-shaped hole 132 is also provided on the bottom plate 13, and the waist-shaped hole 132 allows the horizontal tube portion 221 to pass upward in the vertical direction. It should be noted that the center line of the waist-shaped hole 132 and the center line of the circular hole 131 are set on the center line of the control rod 10 in the thickness direction of the control rod 10, and the eccentric waist groove 11 on the control rod 10 is eccentrically set relative to the center line of the control rod 10.

[0044] As can be seen from the above, when the stirring assembly 20 is assembled on the control rod 10, the transverse tube portion 221 on the second tube body 22 abuts and cooperates with the arc surface 121 of the arc groove 12, and the vertical tube portion 211 on the first tube body 21 is plugged and cooperated with the circular hole 131 on the bottom plate 13. At this time, the transverse tube portion 221 abutting against the arc surface 121 is eccentrically assembled relative to the first tube body 21. In this way, the abutment between the transverse tube portion 221 and the arc surface 121 and the plug-in cooperation between the vertical tube portion 211 and the circular hole 131 can realize the assembly limit of the stirring assembly 20 as a whole on the control rod 10.

[0045] It should be noted that when the stirring assembly 20 is assembled on the control rod 10, the stirring assembly 20 located below the bottom plate 13 can be first moved upward so that the horizontal tube portion 221 passes through the waist-shaped hole 132. At the same time, the vertical tube portion 211 on the first tube body 21 is located below the bottom plate 13. At this time, the stirring assembly 20 as a whole can rotate relative to the control rod 10; then, the horizontal tube portion 221 on the second tube body 22 is driven to move toward the direction of the eccentric waist groove 11, so that the horizontal tube portion 221 is inserted into the eccentric waist groove. 11, and then adjust the position of the stirring assembly 20 until the vertical tube portion 211 on the first tube body 21 is located in the circumferential direction of the circular hole 131 on the bottom plate 13; then, the user can move the vertical tube portion 211, and by driving the vertical tube portion 211 to elastically deform, move the vertical tube portion 211 to the bottom of the circular hole 131, and then push the stirring assembly 20 upward until the horizontal tube portion 221 enters the arc surface 121 of the arc groove 12, so that the stirring assembly 20 can be assembled on the control rod 10. When the stirring assembly 20 needs to be removed from the control rod 10, the user can drive the stirring assembly 20 downward. During this process, the horizontal tube portion 221 can be elastically deformed by pushing the horizontal tube portion 221, and the horizontal tube portion 221 can be separated from the arc surface 121 of the arc groove 12, and the vertical tube portion 211 can be separated from the circular hole 131; then, the horizontal tube portion 221 is driven to move in a direction away from the eccentric waist groove 11, and the horizontal tube portion 221 can be separated from the eccentric waist groove 11; finally, the horizontal tube portion 221 is aligned with the waist-shaped hole 132 on the bottom plate 13 and moves downward, so that the stirring assembly 20 can be removed from the control rod 10.

[0046] like Figure 1 As shown, the gas-liquid integrated stirring device 100 also includes a hose 30, which is mounted on the portion of the second tube body 22 extending downward from the straight tube 23 in the vertical direction, and is connected and communicated with the straight tube 23, so that the gas discharged from the first hose can be discharged through the hose, and the sampled liquid discharged from the second hose can be stirred. In this way, when the second tube body 22 is subsequently cleaned, the hose 30 can be removed from the straight tube 23, which can facilitate the subsequent cleaning of the second tube body 22 and reduce costs.

[0047] As preferably, Figure 1 As shown, a step portion 231 is formed on the straight pipe 23, and the hose 30 can be mounted on the step portion 231; and when the hose 30 is mounted on the step portion 231, the hose 30 can be connected to the step portion 231 in a tight fit manner, and the hose 30 can be detachably connected to the straight pipe 23, which makes it easy to disassemble and assemble the hose 30 on the straight pipe 23.

[0048] In addition, the present application also provides a test equipment, including the gas-liquid integrated stirring device 100 described above.

[0049] The technical features of the above embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0050] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present invention, and are not intended to limit the present invention. As long as they are within the spirit of the present invention, appropriate changes and modifications to the above embodiments are within the scope of protection claimed by the present invention.
