Description

Technical Field

[0001] This utility model relates to the field of waste liquid tank technology, and more specifically, to a waste liquid tank for laboratory use. Background Technology

[0002] In scientific research, teaching experiments, and various industrial laboratories, a large amount of waste liquid is generated. If this waste liquid is not properly treated, it will cause serious pollution to the environment and even endanger human health. As an important piece of equipment for collecting and temporarily storing waste liquid, laboratory waste liquid tanks play a vital role in laboratory safety and environmental protection. Existing waste liquid tanks have a simple structure, and the types of waste thrown into the waste liquid tanks are diverse. For lighter waste items, such as pipette tips and cotton swabs, they may float on the soaking solution and not be fully soaked, resulting in the failure to kill any bacteria that may adhere to them, which does not meet the safety requirements of the laboratory.

[0003] To address the aforementioned issues, specifically the technical problem that existing waste liquid containers cannot adequately soak lightweight waste, resulting in the failure to kill adhering pathogens and thus failing to meet laboratory safety requirements, extensive research revealed a waste liquid container for laboratories with patent publication number CN218609448U. This device, belonging to the field of laboratory technology, utilizes repeated lifting and lowering of a lever to ensure the waste is fully immersed in the soaking solution, guaranteeing the killing of pathogens and ensuring the safety of subsequent processing.

[0004] However, the aforementioned waste liquid containers for laboratories still have some problems. For example, when a large amount of waste is stored inside the container, the waste will accumulate and float at the bottom of multiple plates, affecting the rotation of the subsequent pressure plates. To address these problems, this utility model proposes a waste liquid container for laboratories. Utility Model Content

[0022] The following will refer to the appendix in the embodiments of this utility model. Figures 1-4 The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0023] Please see Figure 1-4 In this embodiment of the present invention, a waste liquid container for laboratory use includes a container body 1, a container lid 5 detachably connected to the top of the container body 1, a disposal port 14 extending through the container lid 5, an inner container 2 movably disposed inside the container body 1, a spiral channel 3 defined inside the inner container 2, openings 15 communicating with the channel 3 extending through both ends of the inner container 2, the opening 15 at the top of the inner container 2 communicating with the disposal port 14, a sealing cap 16 detachably connected to the opening 15 at the bottom of the inner container 2, a plurality of sieve holes 17 extending through the sealing cap 16, a pull rod 8 extending through and movably disposed on the inner container 2 and the container lid 5, the first end of the pull rod 8 extending through and beyond the container lid 5, a limiting component for limiting the pull rod 8 on the container lid 5, and a pressure plate 11 fixedly connected to the second end of the pull rod 8, the pressure plate 11 being disposed between the opening 15 at the bottom of the inner container 2 and the channel 3.

[0024] Specifically, firstly, by pulling lever 8 to move pressure plate 11 away from the opening 15 at the bottom of inner barrel 2, the soaking solution is poured into the waste liquid container, ensuring that the height of the soaking solution inside barrel 1 is less than the maximum height of inner barrel 2. Then, laboratory personnel place pipette tips and other waste into the waste container, aligning them with the disposal port 14 on the lid 5. The pipette tips and other waste enter the opening 15 at the top of inner barrel 2 through the disposal port 14, and then slowly flow along the spiral channel 3 inside inner barrel 2 to the sealing cap 16. To ensure that the pipette tips and other waste are fully soaked, the limiting position of lever 8 can be released, and the inner barrel 2 can be pushed downwards quickly by lever 8. The rapid movement causes the pressure plate 11 to block the sealing cap 16 and move the inner barrel 2 downwards, allowing the soaking solution in the barrel 1 to flow in through the opening 15 at the top of the inner barrel 2, drain through the channel 3 to the sealing cap 16, and discharge any remaining waste in the channel 3 to the bottom of the inner barrel 2. This ensures that the pipette tips and other waste inside the inner barrel 2 are fully soaked. At the same time, the experimenter can repeatedly pull up and down the lever 8 to repeatedly soak the pipette tips and other waste inside the inner barrel 2. This embodiment has a simple structure and operation, eliminates the need for multiple plates, avoids the plates being affected by waste, and ensures the normal use of the device.

[0025] It should be noted that the height of the soaking solution inside the tank 1 can be adjusted according to the moving distance and height of the inner tank 2. Simultaneously, the size of the channel 3, the inner tank 2, and the opening 15 can be adjusted according to the volume of waste such as pipette tips. The opening 15 at the bottom of the inner tank 2 can be extended to ensure sufficient space for accommodating waste such as pipette tips. Furthermore, in this embodiment, the bottom of the inner tank 2 has a funnel-shaped mechanism, and the pressure plate 11 can block the funnel-shaped opening of the inner tank 2. When the pull rod 8 moves the pressure plate 11 up and down, the soaking solution will flow along the inner tank... The flow in channel 3 of the inner tub 2 is used to discharge waste such as pipette tips into the opening 15 inside the inner tub 2. In another embodiment, the pressure plate 11 is replaced by a filter screen. Furthermore, the limiting component can be a positioning bolt, nut, etc. For example, the nut is threaded to the pull rod 8 to limit the pull rod 8. The waste such as pipette tips inside the inner tub 2 can be cleaned by disassembling the tub cover 5 and the sealing cover 16. In addition, the inner tub 2 has multiple through holes 20 at the opening 15 at its top, which facilitates the flow of soaking liquid into the channel 3.

[0026] In this embodiment of the utility model, such as Figure 1 As shown, at least two movable rods 13 are fixedly connected to the top of the inner tub 2. The end of the movable rod 13 facing away from the inner tub 2 passes through and is movably mounted on the lid 5. The end of the movable rod 13 facing away from the inner tub 2 is fixedly connected to a limiting plate 7. A spring 6 is sleeved on the movable rod 13 between the limiting plate 7 and the lid 5. Specifically, the movable rod 13 plays a supporting and limiting role, and the spring 6 enables the inner tub 2 to quickly reset. Furthermore, a sealing gasket 12 is fixedly connected to the outer wall of the pressure plate 11.

[0027] In this embodiment of the utility model, such as Figure 1 As shown, a screen 4 is fitted and movably connected to the outer wall of the inner barrel 2. The screen 4 is fixedly connected to the inner wall of the barrel 1. Specifically, the screen 4 can prevent debris at the bottom of the barrel 1 from floating up, thereby making the soaking more thorough.

[0028] In this embodiment of the utility model, such as Figure 1 and Figure 2 As shown, a positioning hole 19 is provided through the pull rod 8. The limiting component is configured to limit the positioning hole 19. The limiting component includes a fixing plate 18 and a positioning pin 9. The fixing plate 18 is fixed on the bucket lid 5. The positioning pin 9 is movably set on the fixing plate 18 and is configured to position the positioning hole 19. A handle 10 is fixedly connected to the top of the pull rod 8.

[0029] Working principle: First, by pulling the lever 8, the pressure plate 11 is moved away from the opening 15 at the bottom of the inner barrel 2 and positioned by the positioning pin 9. Then, the soaking solution is poured into the waste liquid bucket. Laboratory personnel place pipette tips and other waste into the waste container, aligning them with the disposal port 14 on the lid 5. The pipette tips and other waste enter the opening 15 at the top of the inner barrel 2 through the disposal port 14, and then slowly flow along the spiral channel 3 inside the inner barrel 2 to the sealing cap 16. To ensure that the pipette tips and other waste are fully soaked, the limit on the lever 8 can be released, and the lever 8 can be used to push the inner barrel 2 downwards quickly, causing the pressure plate 11 to press against the sealing cap 16. The shielding mechanism moves the inner barrel 2 downwards, allowing the soaking solution inside the barrel 1 to flow into the opening 15 at the top of the inner barrel 2, drain through the channel 3 to the sealing cap 16, and discharge any remaining waste in the channel 3 to the bottom of the inner barrel 2. This ensures that the pipette tips and other waste inside the inner barrel 2 are fully soaked. Simultaneously, the experimenter can repeatedly pull up and down the lever 8 to repeatedly soak the pipette tips and other waste inside the inner barrel 2. The spring 6 and the movable rod 13 facilitate the quick reset of the inner barrel 2. This embodiment has a simple structure and operation, eliminates the need for multiple plates, avoids the plates being affected by waste, and ensures the normal use of the device.
