[0002] Condensers are important equipment commonly used in laboratories. They are mainly used to promote condensation and play a role in condensation or reflux. They usually consist of two glass tubes, one inside and one outside. The smaller glass tube runs through the larger glass tube, and uses the heat exchange principle to cool the condensable gas and condense it into liquid. Condensers are mainly divided into three types according to their shapes and uses: straight condensers, spherical condensers and serpentine condensers. These condensers are widely used in experiments such as distillation, fractionation and organic preparation, and are indispensable tools in chemical experiments.

[0003] During the experiment, different types of condensers often need to be replaced according to different condensation requirements. However, this replacement process often brings many inconveniences. First, different types of condensers differ in design and specifications, such as length, inner diameter, shape, etc., so they need to be carefully selected and matched when replaced to ensure their compatibility with other parts of the experimental device. This selection and matching process is not only time-consuming, but also prone to errors, affecting experimental efficiency. Secondly, replacing the condenser involves multiple steps such as disassembly and installation, which require careful operation to avoid damaging the experimental device or causing safety hazards.

[0025] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0026] Embodiment 1

[0027] like Figure 1-4 As shown, a condenser provided in this embodiment includes an outer tube 1, an inner tube 2 and an adjusting mechanism 3. The shapes of the inner tubes 2 are different and two or more are provided. The inner tube 2 runs through the outer tube 1. The outer tube 1 has a liquid inlet 11 and a liquid outlet 12. The space between the outer tube 1 and the inner tube 2 forms a condenser channel. The outer tube 1 is provided with a total steam inlet 4. The inlet end 21 of the inner tube 2 is connected to the total steam inlet 4. The adjusting mechanism 3 is arranged inside or at the port of the inner tube 2, and is used to switch the through or closed state of different inner tubes 2. Among them, the inner tube can be a spiral condenser, a straight condenser, a spherical condenser and other different forms of structure. Specifically, the condenser system integrates two or more inner tubes into a single outer tube. This structural feature greatly enriches the diversity of the condensation function, so that a set of equipment can cover a variety of different condensation application scenarios, thereby avoiding the cumbersome steps of frequently disassembling and replacing the condenser in the traditional way. Furthermore, the total steam inlet cleverly arranged on the outer tube not only simplifies the connection process, but also improves the overall sealing and stability of the system. What is particularly critical is that the regulating mechanism is innovatively applied to the main steam inlet. This technical feature gives users the ability to flexibly switch different inner tubes for condensation operations as needed. Through the precise control of the regulating mechanism, users can easily switch the condensation path without interrupting the experimental process, and can meet a variety of condensation needs from low-temperature light condensation to high-temperature heavy condensation, greatly improving experimental efficiency and operational convenience.

[0028] Preferably, the adjustment mechanism 3 is a sliding adjustment mechanism or a rotating adjustment mechanism. In the design of the condenser, the adjustment mechanism is set as a sliding adjustment mechanism or a rotating adjustment mechanism based on comprehensive considerations of operational convenience, accuracy and system reliability. The sliding adjustment mechanism allows the user to switch the inner tube by linear movement, which is intuitive and easy to control, especially in situations where space is limited or quick response is required. The rotating adjustment mechanism achieves switching through a rotating action, which is not only labor-saving to operate, but also able to maintain a high switching accuracy, reducing the risk of leakage caused by improper operation. Both adjustment methods can quickly and accurately adjust the condensation path without interrupting the experimental process, thereby meeting the condensation requirements under different experimental conditions. In addition, both the sliding and rotating adjustment mechanisms have good durability and maintainability, ensuring the long-term stable operation of the condenser system, and are therefore further preferred in the condenser design scheme.

[0029] Preferably, the regulating mechanism 3 is a rotating regulating mechanism, including a rotating cover 31, a total steam outlet 5 is also provided on the outer tube 1, the outlet end of the inner tube 2 is connected to the total steam outlet 5, the rotating cover 31 is arranged at the total steam inlet 4 and / or the total steam outlet 5, and the rotating cover 31 is provided with a passing area 32 for steam / liquid to pass through. Concretizing the regulating mechanism as a rotating regulating mechanism and introducing the design element of the rotating cover is an important improvement in the convenience of operation and sealing performance of the condenser. The setting of the rotating cover allows the user to switch the condensation path by simply rotating, and this operation method is simple, intuitive and easy to master. At the same time, the passing area design on the rotating cover ensures that the liquid can flow smoothly during the switching process, avoiding the decrease in condensation efficiency caused by the blocked path. More importantly, the close fit between the rotating cover and the total steam inlet / outlet effectively improves the sealing performance of the system and reduces the experimental errors and safety hazards caused by leakage. In addition, the rotating regulating mechanism combined with the design of the rotating cover is also convenient for subsequent maintenance and cleaning work, and prolongs the service life of the condenser, so it is a further preferred design scheme for the condenser.

[0030] Preferably, the rotating cover 31 is in the shape of a disc and rotates around the central rotation axis, the passing area 32 is in the shape of a fan, the inlet end 21 of the inner tube 2 located at the total steam inlet 4 is distributed around the rotation axis plane, and the rotating cover 31 selects whether the port of the inner tube 2 is connected or closed during the rotation process. Designing the rotating cover to be disc-shaped and the passing area to be fan-shaped is based on in-depth consideration of the convenience of operation, space utilization and structural stability. The disc-shaped rotating cover is convenient for users to perform rotation operations, and can evenly distribute the channels corresponding to each inner tube, making the switching process smoother and smoother. The fan-shaped passing area makes full use of the space of the rotating cover, so that each inner tube can obtain sufficient circulation area, ensuring the smooth flow of the condensed liquid. In addition, this design also enhances the structural strength of the rotating cover and improves its ability to resist deformation and damage, thereby ensuring the long-term stable operation of the condenser system. More importantly, the layout of the fan-shaped passing area is flexibly combined with the distribution of the inner tube inlet end around the rotation axis plane, and the use frequency and priority of each inner tube can be adjusted according to actual needs, further improving the flexibility and adaptability of the condenser system.

[0031] Preferably, a handle 33 is provided on the outside of the rotating cover 31. In the design of the condenser, a handle is added to the outside of the rotating cover out of in-depth consideration of user experience and operational safety. The design of the handle allows the user to easily hold and apply force when performing the rotation operation, and ensures the stability and accuracy of the operation even when wearing gloves or with wet hands. This improvement not only simplifies the operation process and reduces the risk of misoperation, but also greatly improves work efficiency. In addition, the handle also has certain anti-slip and anti-scalding functions, which can protect the user's hand safety to a certain extent and avoid burns or other injuries caused by careless operation.

[0032] Preferably, a steam main outlet 5 is also provided on the outer tube 1, and the outlet ends of each inner tube 2 are respectively connected to the steam main outlet 5. This design not only simplifies the structure of the system, but also improves the collection and discharge efficiency of the condensate. Through the steam main outlet, the user can easily collect the condensed liquid in all the inner tubes, avoiding the cumbersome steps of discharging the inner tubes one by one in the traditional design. At the same time, the setting of the steam main outlet also makes the discharge process of the condensate more stable and safe, reducing the risk of leakage caused by improper operation.

[0033] Preferably, the regulating mechanism 3 is arranged at the main steam outlet 5, and the regulating mechanism 3 includes a connecting piece 34 and a funnel piece 35. The connecting piece 34 is provided with a through hole 341, and the through hole 341 is respectively connected to the outlet end 22 of each inner tube 2; the funnel piece 35 is connected to the bottom of the connecting piece 34, and the opening of the funnel piece 35 is provided with a baffle 36 that is in contact with the connecting piece 34, and the baffle 36 is provided with a passing area 32 for liquid to pass through. The funnel piece 35 rotates around the central axis to switch the connection between the interior and different through holes 341. This design further improves the sealing and stability of the system. The close fit between the connecting piece and the funnel piece, as well as the design of the baffle, effectively prevents the leakage of condensate during the switching process. This not only ensures the accuracy of the experimental results, but also avoids safety hazards caused by leakage.

[0034] Preferably, two inner tubes 2 are provided, namely a spiral condenser and a straight condenser, and the straight condenser is located inside the spiral structure of the spiral condenser. The spiral condenser increases the condensation area and improves the condensation effect with its unique spiral structure; while the straight condenser is located inside it, further utilizing the remaining space and maximizing the use of space. The combination of the two enables the condenser to achieve a better structure in a limited space. Secondly, the design meets the diverse condensation needs. There are differences in the condensation effect and scope of application between the spiral condenser and the straight condenser. The former is suitable for scenes requiring higher condensation efficiency, while the latter may be more suitable for condensation processes under certain specific conditions. By integrating these two different types of inner tubes in the same condenser, users can flexibly choose to use them according to experimental needs, thereby meeting diverse condensation needs. Under normal circumstances, a spiral condenser is used. When an accident occurs during distillation / reflux and causes the spiral condenser to be blocked, even if the heat source is turned off, the reaction system also has a certain temperature, the boiling state of the reaction system will not stop immediately, the air pressure will continue to rise, and there is a certain risk of eruption. At this time, the condenser can be rotated, and a straight condenser can be selected to replace the condenser without pulling out the condenser. In addition, this structure can also be used to replace the condenser without pulling out the condenser. Specifically, during a step-by-step reaction, adding the reactants of the next step may cause an overly violent reaction and contaminate the inner wall of the condenser. However, the inner wall of the serpentine condenser is not easy to clean. Therefore, when adding the reactants of the next step, a straight condenser can be used first, and then replaced with the serpentine condenser after the reaction speed of the system has stabilized.

[0035] Preferably, the outer tube 1 is a long straight tube body. The long straight tube body is easy to install and fix. The long straight tube body has a regular geometric shape and a stable structural feature, so that the condenser tube can be easily connected and fixed with other equipment or pipelines during installation. This not only simplifies the installation process, but also improves the overall stability and reliability of the system.
