Description

Technical Field

[0001] This utility model belongs to the technical field of boiling water baths, specifically relating to a lifting boiling water bath. Background Technology

[0002] The statements in this section are merely background information related to this utility model and do not necessarily constitute prior art.

[0003] A boiling water bath is a heating device commonly used in experiments and sample processing. Its core function is to provide a stable and uniform high-temperature environment for the sample placed inside by maintaining the liquid inside the bath at a boiling state in order to achieve heat treatment.

[0004] The existing facilities have certain problems during operation. On the one hand, there is a lack of effective anti-splash measures. When samples are immersed or removed, hot water splashes are very likely to occur. In addition, the placement and removal of samples currently rely on manual operation. Operators need to be in direct contact with the boiling water bath environment, which further increases the probability of scalding accidents and poses a serious threat to the personal safety of operators.

[0005] Furthermore, existing technologies rely heavily on manual operation for sample handling in boiling water baths. This not only results in low processing efficiency and a limited number of samples that can be processed at a time, making it difficult to meet the demands of high-throughput experiments or large-scale production, but also necessitates the parallel operation of multiple devices, increasing energy consumption and occupying significant laboratory space. Moreover, manual operation suffers from poor stability and consistency. Differences may occur between different operators or even the same operator at different times, leading to inconsistent sample immersion depths and a lack of standardized container spacing. This directly results in significant temperature variations experienced by samples from the same batch during processing, reducing the comparability of experimental data and affecting the reliability of experimental results and the stability of product quality. Utility Model Content

[0006] To address the aforementioned issues, this invention provides a lifting boiling water bath that avoids the risk of scalding and steam exposure associated with manual operation, ensuring operator safety. It effectively improves processing efficiency, meeting the needs of high-throughput experiments or large-scale production, while reducing equipment energy consumption and space occupancy. Furthermore, it ensures standardized sample immersion depth and container spacing, resulting in uniform heating of samples from the same batch, thus enhancing the comparability of experimental data and the reliability of results.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A lifting boiling water bath includes an outer shell, a screw lifting mechanism is provided at the rear of the outer shell, the output end of the screw lifting mechanism is connected to a lifting frame, a placement frame is provided at the upper end of the lifting frame, the lifting frame drives the placement frame to rise and fall and limits the placement frame; a positioning plate is provided inside the placement frame, and a cover plate is provided at the upper end of the placement frame.

[0008] As a further technical solution, the lifting frame includes a first lifting plate, a second lifting plate, and a limiting block. The second lifting plate is provided at both ends of the first lifting plate, and the first lifting plate and the second lifting plate are an integral structure.

[0009] As a further technical solution, limiting blocks are provided at both ends of the second lifting plate, and the limiting blocks are connected to the second lifting plate.

[0010] As a further technical solution, a limiting hole is provided at the bottom corner of the placement rack, and the placement rack is limited by the limiting hole and the limiting block on the second lifting plate.

[0011] As a further technical solution, several water outlets are provided at intervals on the side wall of the placement rack.

[0012] As a further technical solution, the positioning plate is provided with a number of positioning holes at intervals, and the bottles are placed at the positioning holes.

[0013] As a further technical solution, a first through hole is provided in the middle of the cover plate, and a number of second through holes are provided at intervals at one end of the first through hole; handles are symmetrically provided at the upper end of the cover plate.

[0014] As a further technical solution, an isolation plate is provided at the bottom of the outer shell, and a number of circular holes are spaced apart on the isolation plate.

[0015] As a further technical solution, heating tubes are spaced apart at the lower end of the isolation plate, and the heating tubes are electrically connected to the control screen, which is located at the front of the outer casing.

[0016] As a further technical solution, a first interface and a second interface are provided on the side of the outer casing. A fan is provided at the first interface, and the second interface is connected to a power supply. Both the fan and the lead screw lifting mechanism are electrically connected to the control panel.

[0017] Compared with the prior art, the advantages and positive effects of this utility model are: This invention effectively prevents boiling water splashing by using a cover plate, and also avoids direct contact between operators and the boiling water bath environment. During use, a screw-driven lifting mechanism raises and lowers the lifting frame, which in turn raises and lowers the placement rack. After the lifting frame is raised, the cover plate is lifted by the handle, and the container is placed on the placement rack. When the lifting frame is lowered, it closes the cover plate, and the second through hole on the cover plate covers the top of the container, shielding the top of the placement rack and limiting the container's position. This prevents scalding from boiling water splashing. Furthermore, several drainage holes are provided on the placement rack to gradually drain boiling water as the rack is raised, avoiding the risk of scalding and steam exposure from manual operation, thus ensuring operator safety.

[0018] The upper surface of the placement rack of this utility model is flat, so that the bottles are placed at the same horizontal height. Then, the lifting rack is driven by the screw lifting mechanism, which in turn drives the placement rack to rise and fall synchronously, so that the bottles on the upper part of the placement rack are at the same horizontal height. This ensures that the immersion depth of the samples in the bottles is consistent. In addition, a positioning plate with several positioning holes is set on the placement rack. By simply placing the bottles into the corresponding positioning holes, the spacing between each bottle is guaranteed to be consistent. Ultimately, this ensures that the sample immersion depth and container spacing are standardized, so that the samples in the same batch are heated evenly, improving the comparability of experimental data and the reliability of results.

[0019] The placement rack of this utility model is provided with a limiting hole at the bottom and a limiting block on the lifting frame. By aligning the limiting hole and the limiting block during installation, the installation position of the placement rack can be accurately guaranteed, which effectively improves the overall efficiency. Furthermore, multiple bottles can be placed on the placement rack, and multiple bottles can be simultaneously subjected to boiling water bath, which effectively improves the processing efficiency and can meet the needs of high-throughput experiments or large-scale production, while reducing equipment energy consumption and space occupation.

[0022] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0023] Existing methods have several drawbacks. Firstly, the lack of effective splash prevention measures means that hot water can easily splash during sample immersion or removal. Furthermore, the current manual handling of sample placement and removal, requiring operators to directly contact the boiling water bath, further increases the probability of burns and poses a serious threat to their safety. Secondly, the existing processes involving samples in the boiling water bath rely heavily on manual operation. This not only results in low processing efficiency, with a limited number of samples that can be processed at a time, making it difficult to meet the demands of high-throughput experiments or large-scale production, often requiring multiple devices to operate in parallel, increasing energy consumption and occupying significant laboratory space, but also suffers from poor stability and consistency. Inconsistencies in operation between different operators or even the same operator at different times can lead to inconsistent sample immersion depths and a lack of standardized container spacing. This directly results in significant temperature differences experienced by samples from the same batch during processing, reducing the comparability of experimental data and affecting the reliability of experimental results and the stability of product quality.

[0024] The present invention will now be described in detail with reference to the accompanying drawings. This embodiment discloses a lifting boiling water bath, such as... Figure 1 and Figure 2As shown, it includes an outer shell 2, a screw lifting mechanism 1 is provided at the rear of the outer shell 2, the output end of the screw lifting mechanism 1 is connected to the lifting frame 9, a placement frame 10 is provided at the upper end of the lifting frame 9, the lifting frame 9 drives the placement frame 10 to rise and fall and limits the placement frame 10; a positioning plate 12 is provided inside the placement frame 10, and a cover plate 3 is provided at the upper end of the placement frame 10.

[0025] Specifically, the cover plate 3 effectively prevents boiling water from splashing and avoids direct contact between operators and the boiling water bath environment. During use, the lifting frame 9 is raised and lowered by the screw lifting mechanism 1, which in turn raises and lowers the placement rack 10. After the screw lifting mechanism 1 raises the lifting frame 9, the cover plate 3 is lifted by the handle 33, and the container bottle 8 is placed on the placement rack 10. When the screw lifting mechanism 1 lowers the lifting frame 9, the lifting frame 9 closes the cover plate 3. The second through hole 32 on the cover plate 3 is fitted over the container bottle 8, blocking the top of the placement rack 10 and limiting the position of the container bottle 8. In addition, several drainage holes are provided on the placement rack 10, which can gradually drain the boiling water when the placement rack 10 is raised, avoiding the risk of scalding and steam exposure caused by manual operation, and ensuring the safety of operators.

[0026] The upper surface of the placement rack 10 is flat, and the bottles 8 are placed at the same horizontal height. Then, the lifting mechanism 1 drives the lifting frame 9, which in turn drives the placement rack 10 to rise and fall synchronously, so that the bottles 8 on the upper part of the placement rack 10 are at the same horizontal height. This ensures that the sample immersion depth in the bottles 8 is consistent. In addition, a positioning plate 12 is set on the placement rack 10. The positioning plate 12 has several positioning holes 121. By simply placing the bottles 8 into the corresponding positioning holes 121, the spacing between each bottle 8 can be ensured to be consistent. Ultimately, this ensures that the sample immersion depth and container spacing are standardized, so that the samples in the same batch are heated evenly, improving the comparability of experimental data and the reliability of results.

[0027] like Figure 3 As shown, the lifting frame 9 includes a first lifting plate 91, a second lifting plate 92, and a limiting block 93. The second lifting plate 92 is provided at both ends of the first lifting plate 91, and the first lifting plate 91 and the second lifting plate 92 are integral structures. The limiting block 93 is provided at both ends of the second lifting plate 92, and the limiting block 93 is connected to the second lifting plate 92. Limiting holes are provided at the bottom corners of the placement rack 10, and the placement rack 10 is limited by the limiting holes and the limiting blocks 93 on the second lifting plate 92.

[0028] Specifically, the first lifting plate 91 and the second lifting plate 92 of the placement rack 10 jointly support the placement rack 10 to ensure the stability of the lifting. The bottom of the placement rack 10 is provided with a limiting hole, and the lifting rack 9 is provided with a limiting block 93. When installing, the limiting hole and the limiting block 93 are aligned to ensure that the installation position of the placement rack 10 is accurate, which effectively improves the overall efficiency. In addition, multiple containers 8 can be placed on the placement rack 10, and multiple containers 8 can be boiled in water bath at the same time, which effectively improves the processing efficiency, meets the needs of high-throughput experiments or large-scale production, and reduces equipment energy consumption and space occupation.

[0029] Several water outlets 101 are spaced apart on the side wall of the placement rack 10. Specifically, the water outlets 101 are used to discharge the boiling water inside the placement rack 10 when it is raised. When the screw lifting mechanism 1 drives the placement rack 10 to rise, the boiling water flows out from the water outlets 101, so that there is no boiling water inside the placement rack 10 after it is fully raised, thus avoiding contact between the operator and the boiling water and effectively preventing scalding.

[0030] like Figure 4 As shown, the positioning plate 12 has several positioning holes 121 spaced apart, and the bottles 8 are placed at the positioning holes 121. Specifically, the positioning plate 12 is placed inside the placement rack 10, and the bottles 8 are positioned by the several positioning holes 121 on the positioning plate 12, so that the spacing between the bottles 8 is consistent, thereby ensuring uniform heating and ensuring the reliability of the data.

[0031] A first through hole 31 is provided in the middle of the cover plate 3, and several second through holes 32 are provided at intervals at one end of the first through hole 31. Handles 33 are symmetrically provided at the upper end of the cover plate 3.

[0032] Specifically, the first through hole 31 and the second through hole 32 on the cover plate 3 are designed to ensure that the cover plate 3 can be placed on top of the container bottle 8. The second through hole 32 provides space for the upper part of the container bottle 8, and the first through hole 31 provides space for the screw lifting mechanism 1, thus allowing the cover plate 3 to be closed smoothly. The handle 33 is designed to facilitate picking up or putting down the cover plate.

[0033] A partition plate 7 is provided at the bottom of the outer casing 2, and several round holes are provided on the partition plate 7 at intervals. Specifically, the partition plate 7 is provided to separate the heating tube 11 from the placement rack 10, and the round holes on the partition plate 7 are provided to ensure that the added water can fully contact the heating tube 11 to heat the water, thereby realizing a boiling water bath.

[0034] Heating tubes 11 are spaced apart at the lower end of the isolation plate 7. The heating tubes 11 are electrically connected to the control panel 4, which is located at the front of the outer casing 2. Specifically, the heating tubes 11 are connected to a corresponding power supply, and the control panel 4 controls the power supply to make the heating tubes 11 work to heat the water.

[0035] The outer casing 2 has a first interface 5 and a second interface 6 on its side. A fan is located at the first interface 5, and the second interface 6 is connected to the power supply. The fan and the lead screw lifting mechanism 1 are both electrically connected to the control panel 4.

[0036] Specifically, the fan is used to cool the equipment. The fan is also electrically connected to the power supply and is activated to cool the equipment when it overheats. The screw jack mechanism 1 is existing technology. The screw jack mechanism 1 is a mechanical device that uses the meshing transmission of a screw and a nut to achieve linear lifting motion. The lifting frame 9 is connected to the slider of the screw jack mechanism 1, and the screw jack mechanism 1 is started by controlling the control panel 4.

[0037] Specifically, a water level sensor 13 is installed for real-time monitoring, with a backup float switch for forced power-off. The water level sensor 13 continuously tracks water level changes in the boiling water bath, ensuring the water level remains within a reasonable range. The backup float switch for forced power-off triggers a power cut-off when the water level sensor 13 malfunctions or the water level abnormally drops to a dangerous threshold, immediately stopping the heating device. This can cut off the energy supply in emergencies, fundamentally eliminating the risk of dry burning and further ensuring the safety of equipment and operators.

[0038] A temperature sensor 14 is also provided. Both the water level sensor 13 and the temperature sensor 14 are located inside the outer casing 2. The temperature sensor 14 is used to monitor the water temperature.

[0039] Instructions for using a lifting boiling water bath: Connect the device to the power supply, that is, connect it to the power supply through the second interface 6 on the side of the outer shell 2. Add an appropriate amount of water into the outer shell 2 to ensure that the water level is within a reasonable range. At this time, the water level sensor 13 monitors it in real time. Place the positioning plate 12 into the placement rack 10. According to the number of samples, place the bottles 8 into the positioning holes 121 of the positioning plate 12 to ensure that the spacing between the bottles 8 is consistent.

[0040] The operation control panel 4 sets the heating temperature and lifting program parameters. The control panel 4 then activates the screw lifting mechanism 1, which lifts the lifting frame 9 to remove the cover plate 3, making it easy to confirm the placement status of the container bottle 8. The control panel 4 then initiates the descent program, causing the screw lifting mechanism 1 to simultaneously lower the lifting frame 9 and the placement rack 10, covering the cover plate 3 to create a sealed environment. The container bottle 8 is then immersed in water along with the placement rack 10, and the heating tube 11 heats the water, ensuring consistent immersion depth for samples from the same batch.

[0041] During the reaction, the water level sensor 13 continuously monitors the water level. If an abnormality occurs and the sensor fails, the backup float switch will force a power outage, stopping the heating. The cover plate 3 effectively blocks steam and splashes, ensuring operational safety. After the boiling water bath is complete, the control panel 4 initiates the lifting program. The screw lifting mechanism 1 drives the lifting frame 9 and the placement frame 10 to rise, and then the cover plate 3 is lifted. During the lifting of the placement frame 10, the boiling water inside is discharged through the side wall outlet 101. After it is fully raised, the operator can safely place and remove the container 8. Finally, the control panel 4 is turned off and the power is disconnected. If the equipment overheats, it can be cooled by the fan at the first side interface 5. After completing the operation, any residual water inside the equipment is cleaned.

[0042] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
