Description

Technical Field

[0001] This utility model relates to the field of gas washing bottle technology, and in particular to a glass PTFE gas washing device. Background Technology

[0002] Gas washing bottles are common laboratory instruments used to remove impurities from gases. They work by passing a gas containing impurities into an absorbent liquid inside the bottle, where the two dissolve or react chemically to remove the impurities and purify the gas.

[0003] Chinese Patent CN209576728U discloses a gas washing bottle, comprising an inlet pipe, an outlet pipe, a bottle body, a stopper, a gas washing cylinder, and a secondary inlet pipe. The inlet pipe and the outlet pipe pass through the stopper, and the upper end of the gas washing cylinder is embedded in the stopper for sealing and fixation. The secondary inlet pipe is fixed to the body of the gas washing cylinder. When using this invention, gas reaches the bottom of the inlet pipe and forms uniform small bubbles through small pores, entering the absorbent liquid. The gas then rises along the inner wall of the gas washing cylinder to the exhaust hole at the top of the cylinder body and enters the secondary inlet pipe.

[0004] Regarding the aforementioned technologies, it has been found that the gas washing cylinders can only be used with a fixed number of inlet pipe assemblies, making their function relatively limited. When different needs arise, multiple models of gas washing cylinders need to be carried, which is not only inconvenient to carry but also prone to damage from bumps and knocks. Utility Model Content

[0027] Reference Figure 1 , Figure 2 and Figure 3As shown, a glass PTFE gas scrubbing device includes a gas scrubbing bottle 1. A gas scrubbing bottle cap 2 is installed at the head of the gas scrubbing bottle 1. The gas scrubbing bottle cap 2 includes a connecting shell 21 and a top shell 22. The top shell 22 is installed on the upper end face of the connecting shell 21 and is integrally formed with the connecting shell 21. Adjustable sealing caps 3 are installed at the four ends of the top shell 22. The adjustable sealing caps 3 are detachably and sealed to the top shell 22. An exhaust pipe 4 is also installed at the center of the top shell 22. The exhaust pipe 4 is sealed and fixedly connected to the top shell 22. The washing bottle 1 is used to hold liquid and serves as the main structure of the washing device. A washing bottle cap 2 is installed at the head of the washing bottle 1 to seal it, ensuring stable use of the liquid. The washing bottle cap 2 is designed with a connecting shell 21 and a top shell 22 that work together. For ease of use, the connecting shell 21 connects to the washing bottle 1, and the top shell 22 is located on top of the connecting shell 21. An adjustable cap 3 is installed on the top shell 22, sealing the four corners of the top shell 22. When a specific adjustable cap 3 is needed, it can be installed in reverse. An external gas supply pipe is connected to the adjustable cap 3 for gas supply. An exhaust pipe 4 is installed at the center of the top shell 22, allowing the washing gas to be stably discharged to the outside. The gas washing bottle 1 includes a bottle body 11 and a bottle mouth 12. The bottle mouth 12 is located at the head of the bottle body 11 and is integrally formed with the bottle body 11. An external thread is provided on the outer surface of the bottle mouth 12. By designing the gas washing bottle 1 with a structure in which the bottle body 11 and the bottle mouth 12 fit together, the bottle body 11 is used to hold the gas-absorbing liquid when it is easy to use, while the bottle mouth 12 ensures the stable installation of the gas washing bottle cap 2.

[0028] Reference Figure 3 and Figure 4 As shown, the connecting shell 21 includes a sleeve 211 and an outer ear plate 212. The outer ear plate 212 is symmetrically installed on both sides of the sleeve 211 and is integrally formed with the sleeve 211. The inner side of the sleeve 211 is provided with an internal thread for connecting to the bottle mouth 12. The structure of the connecting shell 21 ensures that it can be connected to the bottle mouth 12 of the gas washing bottle 1 during use, while the outer ear plate 212 ensures better rotation of the connecting shell 21 for assembly and disassembly. The top shell 22 has mounting grooves 221 for installing the adjustable cap 3 on its four corners, and the lower end face of the top shell 22 has a connecting through hole 222 that communicates with the mounting grooves 221. By providing mounting grooves 221 on the four corners of the top shell 22, it is convenient to install the adjustable cap 3 through the mounting grooves 221 during use, ensuring that the adjustable cap 3 can stably seal the mounting groove 221 during use.

[0029] Reference Figure 5 As shown, the adjustable cover 3 includes a plug-in housing 31 and an operating pull ring 32. The operating pull ring 32 is installed on one side of the plug-in housing 31 and is rotatably connected to the plug-in housing 31. By designing the adjustable cover 3 into a structure where the plug-in housing 31 and the operating pull ring 32 cooperate, the operating pull ring 32 can be used to ensure better pulling operation of the plug-in housing 31 during use, making it easier to install and use the adjustable cover 3. A side hole 311 is provided on the side of the plug-in housing 31 away from the operating pull ring 32, and a mating hole 312 corresponding to the connecting through hole 222 is provided on the lower end face of the plug-in housing 31. The mating hole 312 communicates with the side hole 311. A side hole 311 is provided on the side of the plug-in housing 31 away from the operating pull ring 32, allowing an external air inlet pipe to be connected through the side hole 311 for use. Simultaneously, a mating hole 312 is provided on the lower end face of the plug-in housing 31, allowing communication between the mating hole 312 and the side hole 311 for easy operation, ensuring a stable flow of external gas into the gas washing bottle 1. An annular groove is provided on the lower end face of the plug-in housing 31, and a sealing ring 33 is installed on the annular groove, engaging and securing it to the plug-in housing 31. The annular groove on the lower end face of the plug-in housing 31 facilitates the installation of the sealing ring 33, allowing the plug-in housing 31 to be installed within the annular groove.

[0030] In this embodiment, when only one air inlet pipe is needed in actual use, one of the adjustable caps 3 can be pulled out from the mounting groove 221 of the top shell 22, and then the adjustable cap 3 can be flipped and inserted into the mounting groove 221. In this way, the mating hole 312 on the adjustable cap 3 can correspond to the connecting through hole 222. After the external air inlet pipe is inserted into the side hole 311, air can be stably supplied to the gas washing bottle 1. After the gas is washed by the liquid in the gas washing bottle 1, it can be stably discharged from the exhaust pipe 4. When multiple air inlet pipes need to be connected, several adjustable caps 3 can be installed in reverse in the mounting groove 221.

[0031] The above are preferred embodiments of this utility model. Those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above. Any obvious improvements, substitutions or modifications made by those skilled in the art based on this utility model shall fall within the protection scope of this utility model.
