生化等领域的发展离不开实验人员在实验室内完成的各项专业试验,而随着知识的扩展,实验过程难免会用到对人体有害且易挥发的溶剂,诸如浓盐酸、浓硝酸、冰醋酸、甲醇、浓氨水、乙醚、丙酮和氯仿等溶液,有毒性或强腐蚀性,具有刺激性气味,且容易挥发,多被用于调节溶液pH值、电泳缓冲液、银镜反应、实验动物麻醉、擦拭显微镜油镜、组织固定、提取RNA实验等。但是,由于这种有毒溶液的挥发性极强,且存在一定毒性危害人体健康,一般需要在实验开始前配制并立即使用。而单单使用量筒测体积、烧杯混匀和玻璃棒搅拌的方式进行溶液配制,不仅给实验准备带来了巨大的负担,配制过程挥发的有毒溶液还会对实验人员的身体形成一定危害。除了科研实验需要大量配制这些有毒易挥发溶液,教学实验中学生人数众多,需要量也非常大,实验人员手动配制溶液的工作量大且难以保证精度,存在精度差效率低而且危害大的问题。The development of fields such as biochemistry is inseparable from the various professional experiments completed by experimentalists in the laboratory. With the expansion of knowledge, the experimental process will inevitably use solvents that are harmful to the human body and volatile, such as concentrated hydrochloric acid, concentrated nitric acid, Solutions such as glacial acetic acid, methanol, concentrated ammonia, ether, acetone, and chloroform are toxic or highly corrosive, have pungent odors, and are easily volatile. They are often used to adjust the pH of solutions, electrophoresis buffers, silver mirror reactions, and experiments. Animal anesthesia, wiping microscope oil lenses, tissue fixation, RNA extraction experiments, etc. However, since this toxic solution is extremely volatile and has certain toxicity that is harmful to human health, it generally needs to be prepared before the experiment starts and used immediately. However, simply using a measuring cylinder to measure volume, mixing in a beaker, and stirring with a glass rod for solution preparation not only brings a huge burden to the experimental preparation, but the toxic solution volatilized during the preparation process will also cause certain harm to the body of the experimenter. In addition to scientific research experiments that require the preparation of large quantities of these toxic and volatile solutions, there are also many students in teaching experiments, and the quantities required are also very large. Experimenters have a heavy workload in manually preparing solutions and it is difficult to ensure accuracy. There are problems such as poor accuracy, low efficiency and great harm.

It is highly efficient and does not require manual preparation and packaging. The completely enclosed preparation process also prevents harmful volatile solutions from evaporating into the air and causing injury to experimenters due to inhalation or contact. Specifically, the first liquid outlet device 11 and the second liquid outlet device 31 are both provided with the second chamber 4, and the second chamber 4 of each first liquid outlet device 11 is The liquid inlet 41 is used to place a single required solution, the liquid outlet 42 is connected with the first chamber 21, and the liquid outlet 42 is provided with the overflow valve 421 to control the The opening and closing of the liquid outlet 42 cooperates with the liquid pushing assembly 43 to control the amount of liquid, which is more precise than manual control; and the second chamber 4 of the second liquid outlet device 31 The liquid inlet 41 is connected to the first chamber 21.

Of course, the liquid pushing assembly 43 can also be set as an ordinary liquid pushing rod, and the flow rate can be measured through the above-mentioned flow valve or weight sensing device. However, on the one hand, it is difficult to install, and on the other hand, it is easily affected by external factors. Compared with this method, In the embodiment, the piston rod 431 is provided and the displacement sensor 44a is provided corresponding to the piston rod 431. It is easy to install and the piston rod 431 will not move at will when it is pressed. It is difficult for the measurement results to be affected by external factors, making the measurement Higher accuracy.
需要注意的是,所述位移传感器44a检测所述活塞杆431的位移方式可以是采用磁吸结构,通过在所述第二腔室4内的所述活塞杆431带动所述第二腔室4外的结构同步移动以使得所述位移传感器44a检测所述第二腔室4外的结构即可得到所述活塞杆431的位移,此种方式结构占地小便于安装但对测量精度存在一定影响;也可以是检测所述活塞杆431未伸入所述第二腔室4内的部位的位移,此种方式精度影响小但所述活塞杆431的长度较长,所需安装空间大;还可以是采用其他方式例如视觉感应、磁性感应等,在所述活塞杆431上设置感应结构使得所述第二腔室4外的所述位移传感器44a可感应到所述第二腔室4内的所述活塞杆431的位移,此种方式占用面积小且精度高,但故障后难以维护。以上情况各有优劣,但能实现对位移的检测即可,此处不进行限定,针对实际使用情况进行选择即可。It should be noted that the displacement sensor 44a can detect the displacement of the piston rod 431 by using a magnetic attraction structure, and the piston rod 431 in the second chamber 4 drives the second chamber 4 The external structure moves synchronously so that the displacement sensor 44a detects the external structure of the second chamber 4 to obtain the displacement of the piston rod 431. This structure occupies a small area and is easy to install, but it has a certain impact on the measurement accuracy. ; It can also be used to detect the displacement of the part of the piston rod 431 that does not extend into the second chamber 4. This method has little impact on accuracy but the length of the piston rod 431 is longer and requires a large installation space; also Other methods such as visual induction, magnetic induction, etc. may be used to provide a sensing structure on the piston rod 431 so that the displacement sensor 44a outside the second chamber 4 can sense the displacement inside the second chamber 4. The displacement of the piston rod 431 occupies a small area and has high precision, but it is difficult to maintain after failure. Each of the above situations has its own advantages and disadvantages, but as long as it can detect the displacement, there is no limit here, and the selection can be based on the actual use situation.
具体地,所述驱动组件432包括气泵432a,所述气泵432a连通所述第二腔室4的另一端,所述气泵432a用以提供气压推动所述活塞杆431移动。所述驱动组件可以是液压杆、气缸或气泵等,在本实施例中所述驱动组件设置为所述气泵432a,通过所述气泵432a提供稳定气压对所述活塞杆431进行推动,一方面气体推动无需设置额外的机械结构,便于安装使用;另一方面气压可保证所述活塞杆431受力均匀,避免所述活塞杆431倾斜造成测定偏差甚至所述活塞杆431卡死的问题。所述活塞杆431的驱动方式采用气压推动,即需要保证密封性,则所述位移传感器44a检测所述活塞杆431位移的方式不能采用例如上述的检测所述活塞杆431未伸入所述第二腔室4内的部位的位移的方式。Specifically, the driving assembly 432 includes an air pump 432a. The air pump 432a is connected to the other end of the second chamber 4. The air pump 432a is used to provide air pressure to push the piston rod 431 to move. The driving component may be a hydraulic rod, a cylinder or an air pump, etc. In this embodiment, the driving component is configured as the air pump 432a, which provides stable air pressure to push the piston rod 431. On the one hand, the air pump 432a provides stable air pressure to push the piston rod 431. There is no need to install additional mechanical structures for pushing, which is convenient for installation and use; on the other hand, the air pressure can ensure that the piston rod 431 is evenly stressed, avoiding the problem of measurement deviation caused by the tilt of the piston rod 431 or even the problem of the piston rod 431 getting stuck. The driving mode of the piston rod 431 is driven by air pressure, that is, the sealing performance needs to be ensured. The displacement sensor 44a cannot detect the displacement of the piston rod 431 by, for example, the above-mentioned method of detecting that the piston rod 431 does not extend into the third position. The way the parts in the second chamber 4 are displaced.
进一步地,所述气泵432a提供的额定气压为P,所述溢流阀421的阈值压强为P0,则P=P0。所述活塞杆431正常被驱动时,受所述溢流阀421的阈值压强的控制,所述活塞杆431位于溶液的一侧的液压应当与所述溢流阀421的阈值压强相等,故所述气泵432a的额定气压必须大于等于所述溢流阀421的阈值压强,所述活塞杆431才会被驱动以推动溶液使所述溢流阀421开启。而如果所述气泵432a的额定气压大于所述溢流阀421的阈值压强,当所述气泵432a停止工作时,所述活塞杆431受气体推动的一侧的气压存在下降的过程,就算气压下降的速率极快,也会存在气压大于所述活塞杆431另一侧液压的情况,使得所述气泵432a关闭后所述溢流阀421不能及时响应关闭,而造成流出溶液过多导致配制不精准的问题。故本实施例中,设定所述气泵432a的额定气压与所述溢流阀421的阈值压强相等,在正常运行过程中,所述气泵432a开启时,所述活塞杆431两侧的压强相等且等于所述气泵432a的额定气压与所述溢流阀421的阈值压强,所述溢流阀421得以开启,此时流出溶液达到所需溶液体积时,所述气泵432a立即停止,所述活塞杆431受气体推动的一侧气压立即低于所述溢流阀421的阈值压强,使得所述溢流阀421得以迅速关闭以避免溶液受所述气泵432a停止后气压降低过程中的惯性额外流出的情况,从而在所述溢流阀421与所述气泵432a的压强联动中,实现了提高所述溢流阀421关闭的灵敏度从而提高溶液配制或分装的准确性的作用。Further, the rated air pressure provided by the air pump 432a is P, and the threshold pressure of the relief valve 421 is P0, then P=P0. When the piston rod 431 is normally driven, it is controlled by the threshold pressure of the overflow valve 421. The hydraulic pressure of the piston rod 431 on the side of the solution should be equal to the threshold pressure of the overflow valve 421, so the The rated air pressure of the air pump 432a must be greater than or equal to the threshold pressure of the overflow valve 421 before the piston rod 431 can be driven to push the solution to open the overflow valve 421. If the rated air pressure of the air pump 432a is greater than the threshold pressure of the relief valve 421, when the air pump 432a stops working, the air pressure on the side of the piston rod 431 pushed by the gas will decrease. Even if the air pressure decreases, The speed is extremely fast, and there may be situations where the air pressure is greater than the hydraulic pressure on the other side of the piston rod 431, so that the overflow valve 421 cannot respond to closing in time after the air pump 432a is closed, resulting in too much outflowing solution and inaccurate preparation. The problem. Therefore, in this embodiment, the rated air pressure of the air pump 432a is set to be equal to the threshold pressure of the relief valve 421. During normal operation, when the air pump 432a is turned on, the pressures on both sides of the piston rod 431 are equal. And equal to the rated air pressure of the air pump 432a and the threshold pressure of the overflow valve 421, the overflow valve 421 is opened. At this time, when the outflow solution reaches the required solution volume, the air pump 432a stops immediately, and the piston The air pressure on the side of the rod 431 pushed by the gas is immediately lower than the threshold pressure of the overflow valve 421, so that the overflow valve 421 can be quickly closed to avoid additional outflow of the solution due to the inertia during the reduction of air pressure after the air pump 432a stops. Therefore, in the pressure linkage between the overflow valve 421 and the air pump 432a, the sensitivity of closing the overflow valve 421 is improved, thereby improving the accuracy of solution preparation or dispensing.
此外,所述活塞杆431与所述第二腔室4的另一端的端部之间连接有一弹性结构45;所述第二腔室4的另一端还设置有一排气口46,所述排气口46用于泄压使所述弹性结构45可驱动所述活塞杆431回到所述第二腔室4的另一端的端部。通过设置所述排气口46用以完全排出所述气泵432a泵入所述第二腔室4内的气体,同时设置所述弹性结构45可将已完成推动溶液流出动作后的所述活塞杆431带回靠近所述气泵432a的一侧,以保持所述第二腔室4溶液侧的容积的最大化,同时也便于清洗时对容置溶液侧的内壁的完全清洗,避免所述活塞杆431未回位时阻挡对内壁的清洗。所述弹性结构45可以是弹簧或弹性橡胶等,在本实施例中采用弹簧结构,结构简单且价格便宜,实用性强。In addition, an elastic structure 45 is connected between the piston rod 431 and the other end of the second chamber 4; an exhaust port 46 is also provided at the other end of the second chamber 4. The air port 46 is used to relieve pressure so that the elastic structure 45 can drive the piston rod 431 back to the other end of the second chamber 4 . The exhaust port 46 is provided to completely discharge the gas pumped into the second chamber 4 by the air pump 432a. At the same time, the elastic structure 45 is provided to remove the piston rod after completing the action of pushing the solution out. 431 is brought back to the side close to the air pump 432a to maintain the maximum volume of the solution side of the second chamber 4, and at the same time, it is also convenient to completely clean the inner wall of the solution side during cleaning to avoid the piston rod. When 431 is not returned to position, it blocks the cleaning of the inner wall. The elastic structure 45 may be a spring or elastic rubber. In this embodiment, a spring structure is used, which has a simple structure, is cheap, and has strong practicability.

During the next dispensing operation, the valve body is opened, so that the piston rod 431 can continue to advance following the previous dispensing operation to ensure that each dispensing operation is completed. The same movement distance of the piston rod 431 detected by the displacement sensor 44a is equivalent to the corresponding amount of mixed solution, which avoids the piston rod 431 retreating after a dispensing operation, so that when dispensing again, the displacement sensor 44a detects The same displacement results in a decrease in liquid output.
