Description

Technical Field

[0001] This utility model relates to the field of laboratory equipment technology, and in particular to a multifunctional central table for laboratory use. Background Technology

[0002] In traditional laboratories, open flame equipment such as alcohol lamps are often used for heating operations, which poses significant safety hazards, such as the risk of fire and burns to operators. With the development of technology, the types of experiments that need to be conducted in laboratories are increasing, and the functional requirements for laboratory benches are also becoming more demanding. Traditional laboratory benches have relatively simple functions and single uses. Different types of laboratory benches are suitable for different experimental scenarios, requiring dedicated benches for specific purposes. Laboratories need to purchase different types of laboratory benches according to their uses, which is costly and takes up a lot of space. Therefore, there is a need to develop a multifunctional laboratory bench to meet a variety of experimental needs.

[0003] Currently, when conducting experiments on the central platform, a cleaning pool is set up on the platform and connected to the sewer to facilitate the cleaning and discharge of liquids after the experiment. However, for experimental waste liquids that are polluting, they cannot be directly discharged into the sewer. At this time, an additional collection bucket is required, which makes the treatment inconvenient. In addition, the existing central platform experiments are functionally limited and require a lot of additional auxiliary experimental equipment, which makes it difficult to conduct experiments quickly. Existing patent (publication number: CN214346593U) discloses a multifunctional central workbench for laboratories. This workbench features a waste liquid storage chamber and a tool chamber inside. A cleaning pool at the top of the workbench is connected to both the waste liquid storage chamber and the drain, allowing different experimental waste liquids to be discharged into either the waste liquid storage chamber or the drain as needed. This avoids direct discharge of experimental waste liquid into the sewer, preventing pollution, and eliminates the need for two sets of cleaning pools, saving workbench space. A motor-driven turntable is installed at the top of the workbench, allowing experimental items to rotate on the workbench, facilitating stirring or rotation during experiments. Combined with a support plate and electric actuator within the support frame, it also facilitates the placement and removal of test tubes during experiments. Overall, this design offers enhanced functionality, addressing the issue of limited functionality in current central workbench designs and making it more convenient for use during experiments.

[0004] To address the aforementioned issues, existing patents offer solutions. However, current multifunctional central workbenches for laboratories typically lack a safe heating structure that uses electric heating to replace open flames, making it difficult to avoid safety risks posed by open flames. This results in fire hazards and the risk of burns to operators, affecting the safety of experimental operations. Furthermore, the lack of adjustable water outlet positions and flow control structures makes it difficult to flexibly adjust the water outlet status according to experimental needs. Consequently, fixed water outlet positions lead to operational limitations, and improper flow rates result in water waste or incomplete cleaning, impacting the convenience and efficiency of experimental operations.

[0005] To address this, a multifunctional central console for laboratory use is proposed. Utility Model Content

[0006] The purpose of this invention is to provide a multifunctional central table for laboratory use, which solves the problems of existing multifunctional central tables for laboratory use that usually lack a safe heating structure that uses electric heating to replace open flames, making it difficult to avoid the safety risks caused by open flames, thus posing fire hazards and the risk of burns to operators, affecting the safety of experimental operations. In addition, the lack of an adjustable water outlet position and flow control structure makes it difficult to flexibly adjust the water outlet state according to experimental needs. As a result, the fixed water outlet position leads to operation limitations, and improper flow causes water waste or incomplete cleaning, affecting the convenience and efficiency of experimental operations.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a multifunctional central table for laboratory use, comprising a central table body, an electric heating control component disposed on the left side of the top of the central table body, and an adjustable water outlet component disposed on the right side of the top of the central table body.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-5 The present invention provides the following technical solution: A multifunctional central table for laboratory use includes a central table body 1. An electric heating control component 4 is arranged on the left side of the top of the central table body 1, and an adjustable water outlet component 5 is arranged on the right side of the top of the central table body 1. The electric heating control component 4 includes a heating base 401 fixedly connected to the top of the central table body 1. An electric heating plate 402 is fixedly connected to the top of the heating base 401. A protective support 403 is fixedly connected to the top of the heating base 401. A lifting electric cylinder 404 is fixedly connected to the outside of the protective support 403. A protective railing 405 is fixedly connected to the output end of the lifting electric cylinder 404. The side of the protective railing 405 away from the lifting electric cylinder 404 is slidably connected to the protective support 403. A temperature control knob 406 is arranged on the left side of the heating base 401, and a temperature control main board 407 is arranged on the right side of the heating base 401.

[0020] In this embodiment: By placing the experimental container to be heated on the electric heating plate 402 on top of the heating base 401, the lifting cylinder 404 starts to work. The output end of the lifting cylinder 404 drives the protective railing 405 to move upward. Since the side of the protective railing 405 away from the lifting cylinder 404 is slidably connected to the protective support 403, the protective railing 405 will rise smoothly along the inner side of the protective support 403 until it reaches a suitable height, forming a safety barrier to prevent the operator from accidentally touching the high-temperature electric heating plate 402 or the experimental container during the experiment and being burned. At the same time, it can also block liquids that may splash out during heating. Afterward, the operator turns the temperature control knob 406 on the left side of the heating base 401. The temperature control knob 406 transmits the adjustment signal to the temperature control main board 407 on the right side of the heating base 401 through the internal mechanical structure. After receiving the signal, the temperature control main board 407 controls the electric heating plate 402 to be energized and heated according to the set temperature parameters. The heat generated by the electric heating plate 402 is transferred to the experimental container placed on it through heat conduction, thereby heating the experimental material.

[0021] Specifically, such as Figure 3 As shown, the adjustable water outlet assembly 5 includes a mounting base 501 fixedly connected to the top of the central platform body 1. A water delivery pipe 502 is provided inside the mounting base 501, and a water delivery pump 503 is provided at the bottom of the water delivery pipe 502.

[0022] Specifically, such as Figure 3 As shown, the top of the water pump 503 is equipped with an adjustment knob 504, the top of the water pipe 502 is connected to a connecting hose 505, and the outside of the connecting hose 505 is connected to an outlet pipe 506.

[0023] Specifically, such as Figure 3 As shown, an adjustment support 507 is fixedly connected to the outer side of the central platform body 1, and an adjustment connecting seat 508 is slidably connected to the inner side of the adjustment support 507. The side of the adjustment connecting seat 508 away from the adjustment support 507 is fixedly connected to the connecting hose 505.

[0024] In this embodiment: when it is necessary to clean experimental equipment or add liquid during the experiment, the water delivery pipe 502 inside the mounting base 501 will draw water from the water source through the water delivery pump 503 at the bottom and deliver it to the water delivery pipe 502. The operator can rotate the adjustment knob 504 on the top of the water delivery pump 503. The adjustment knob 504 controls the power of the water delivery pump 503 to change the speed and flow rate of the water flow to adapt to different usage needs. For example, when cleaning small equipment, reducing the flow rate can avoid water waste, and when rinsing larger containers, increasing the flow rate can improve cleaning efficiency. The connecting hose 505 connected to the top of the water delivery pipe 502 has good flexibility and can be adjusted according to the operator's needs. The water outlet 506, connected to the outside of the connecting hose 505, serves as the final outlet for the water flow, precisely guiding the water to the desired location. Meanwhile, the adjusting support 507 on the outside of the central platform 1 provides a sliding track for the adjusting connecting seat 508. Since the side of the adjusting connecting seat 508 away from the adjusting support 507 is fixedly connected to the connecting hose 505, when the operator pushes the connecting hose 505, it will cause the adjusting connecting seat 508 to slide along the inside of the adjusting support 507, thereby flexibly adjusting the position of the water outlet 506 so that it can be precisely aligned with the utensils to be cleaned or the containers to be filled with water, greatly improving the convenience of operation.

[0025] Specifically, such as Figure 4 As shown, a water collection tank 2 is fixedly connected to the top of the central platform body 1, and a filter baffle 3 is installed on the top of the water collection tank 2.

[0026] Specifically, such as Figure 4 As shown, the bottom of the water collection tank 2 is connected to a drain pipe 6, and a filter 7 is fixedly connected inside the central platform body 1. The filter 7 is connected to the drain pipe 6.

[0027] In this embodiment: By setting up a water collection tank 2 and a filter baffle 3, during the experiment, when waste liquid is generated or experimental equipment needs to be cleaned, the operator can directly pour the waste liquid or cleaning wastewater into the water collection tank 2. At this time, the filter baffle 3 at the top of the water collection tank 2 will play a role. It can intercept solid impurities mixed in the waste liquid, such as experimental residues and undissolved particles, to prevent these impurities from directly entering the pipe below, preventing the pipe from being blocked, and ensuring the smooth progress of the subsequent waste liquid treatment process. By setting up a drain pipe 6 and a filter 7, the waste liquid intercepted by the filter baffle 3 will flow into the bottom of the water collection tank 2, and then be transported to the filter 7 fixed inside the central platform body 1 through the drain pipe 6 connected to the bottom of the water collection tank 2. The filtration structure inside the filter 7 will further treat the waste liquid, removing harmful substances or fine impurities. The filtered liquid can avoid direct discharge and environmental pollution, and can also protect the sewer system from corrosion or blockage.

[0028] Specifically, such as Figure 5 As shown, a placement seat 8 is fixedly connected to the top of the central table body 1, a test tube holder 9 is fixedly connected inside the placement seat 8, and a protective pad 10 is fixedly connected to the bottom of the placement seat 8.

[0029] Specifically, such as Figure 1 As shown, a support leg 11 is fixedly connected to the bottom of the central platform body 1, and a rubber foot pad 12 is fixedly connected to the bottom of the support leg 11.

[0030] In this embodiment: by setting up a placement seat 8, a test tube holder 9, and a protective pad 10, before the experiment, the operator can place the test tubes, centrifuge tubes, and other equipment required for the experiment in the placement seat 8. The test tube holder 9 inside the placement seat 8 will firmly clamp the test tubes through the slots to prevent the test tubes from tipping over due to collisions or vibrations during the experiment, thus avoiding spillage of the liquid inside the test tubes or breakage of the test tubes. The protective pad 10 at the bottom of the placement seat 8 is made of a cushioning material, which can reduce the direct contact between the test tubes and the hard surface of the placement seat 8, buffer the impact of slight vibrations, and protect the bottom of the test tubes from damage. By setting up support legs 11 and rubber feet 12, the rubber feet 12 can increase the friction with the ground, prevent the central platform from sliding due to collisions or pushing during the experiment, and ensure the stability of the experimental platform. At the same time, the rubber material has a certain degree of elasticity, which can buffer the shaking caused by uneven ground and reduce the impact of vibration on the experimental operation.

[0031] Working Principle: During experiments using this multi-functional laboratory central table, before the experiment, the required test tubes and other experimental instruments can be placed in the placement seat 8 on top of the central table body 1. The test tube holder 9 inside the placement seat 8 can stably hold the test tubes to prevent them from tipping over, while the protective pad 10 at the bottom of the placement seat 8 can reduce direct collisions between the test tubes and the placement seat 8, avoiding damage to the test tubes due to slight vibrations. When heating experiments are required, the operator places the experimental container to be heated on the electric heating plate 402 on top of the heating base 401 of the electric heating control component 4. The heating base 401 provides stable support for the entire electric heating structure. At this time, the protective support 403 located on the outside of the heating base 401 plays a crucial supporting role. The protective railing 405 is supported by a lifting cylinder 404 fixed on its outer side. The output end of the lifting cylinder 404 drives the protective railing 405 to move upward. Since the side of the protective railing 405 away from the lifting cylinder 404 is slidably connected to the protective support 403, the protective railing 405 will rise smoothly along the inner side of the protective support 403 until it reaches a suitable height, forming a safety barrier to prevent operators from accidentally touching the high-temperature electric heating plate 402 or experimental containers and being burned during the experiment. It can also block liquids that may splash out during the heating process. Subsequently, the operator turns the temperature control knob 406 on the left side of the heating base 401. The temperature control knob 406 transmits the adjustment signal to the temperature control main board 407 on the right side of the heating base 401 through the internal mechanical structure. After receiving the signal, the temperature control mainboard 407 controls the electric heating plate 402 to start working according to the set temperature parameters. The electric heating plate 402 generates heat after being powered on, which is transferred to the experimental container placed on it through heat conduction, thus heating the experimental material. During the heating process, the temperature control mainboard 407 monitors the temperature of the electric heating plate 402 in real time. If the temperature exceeds the set value, it automatically adjusts the power of the electric heating plate 402 to ensure that the heating temperature remains stable within the required range, guaranteeing the accuracy and safety of the experiment. After the heating experiment is completed, the lifting cylinder 404 is operated again, causing its output end to drive the protective railing 405 to slide down along the protective support 403 until the protective railing 405 reaches its lowest position, facilitating the operator to place and remove the experimental container. If the experiment is overdone... During the process, operations such as cleaning experimental equipment or adding liquids are required. The water delivery pipe 502 inside the mounting base 501 is connected to a water source. The water delivery pump 503 at the bottom of the water delivery pipe 502 starts working, pumping water from the water source into the water delivery pipe 502. The operator can turn the adjustment knob 504 on the top of the water delivery pump 503. The adjustment knob 504 controls the power of the water delivery pump 503 to change the speed and flow rate of the water flow to adapt to different usage needs. For example, the flow rate is reduced when cleaning small equipment, and the flow rate is increased when rinsing larger containers. The connecting hose 505 connected to the top of the water delivery pipe 502 has good flexibility and can be adjusted according to the operator's needs. The outlet pipe 506 connected to the outside of the connecting hose 505 serves as the final outlet of the water flow.Water is guided to the desired location. Simultaneously, the adjusting support 507 on the outer side of the central platform 1 provides a sliding track for the adjusting connecting seat 508. The side of the adjusting connecting seat 508 away from the adjusting support 507 is fixedly connected to the connecting hose 505. The operator can push the connecting hose 505, causing the adjusting connecting seat 508 to slide along the inner side of the adjusting support 507, thereby adjusting the position of the water outlet pipe 506 so that it can be precisely aligned with the equipment to be cleaned or the container to be filled with water, improving operational convenience. Waste liquid or cleaning wastewater generated during the experiment can be directly poured into the water collection tank 2 at the top of the central platform 1. The filter baffle 3 at the top of the water collection tank 2 can intercept solid impurities in the waste liquid, preventing larger particles from entering the pipe and causing blockage. After passing through the filter baffle 3, the waste liquid flows into the bottom of the water collection tank 2, and then through the connected drain pipe 6 to the filter 7 fixed inside the central platform 1. The filter 7 filters the waste liquid, removing harmful substances or impurities, avoiding direct discharge and pollution.

[0032] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
