[0002]目前的实验室废料收集桶一般还采用传统螺纹盖结构依赖人工旋紧,每次进行废液倾倒时都需拧开螺纹盖,使用完成后再次拧紧螺纹盖,每日需多次开闭桶盖,累计占用实验人员有效工作时间,密封效果完全依赖操作者施加的旋紧力度,力度不足导致泄漏,过度旋紧则加速螺纹磨损,频繁摩擦导致螺纹滑牙,盖体闭合后存在微间隙,挥发性有机物(VOCs)从缝隙逸散
[0010]The beneficial effects of this utility model are: 1. This utility model can avoid the need to unscrew the threaded cap every time waste liquid is poured, and to open and close the bucket cap multiple times, thus accumulating the effective working time; 2. This utility model can effectively prevent the sealing effect of the waste liquid bucket from depending entirely on the tightening force applied by the operator, which can easily lead to leakage if the force is insufficient. It can also prevent excessive tightening from accelerating thread wear and frequent friction from causing the thread to strip, and further prevent volatile organic compounds (VOCs) from escaping from the gaps.

Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of laboratory waste liquid collection, specifically a laboratory waste liquid collection bucket. Background Technology
[0002] Currently, laboratory waste collection containers generally still use traditional threaded cap structures that rely on manual tightening. The threaded cap must be unscrewed every time waste liquid is poured out, and tightened again after use. The cap needs to be opened and closed multiple times a day, which consumes the effective working time of laboratory personnel. The sealing effect depends entirely on the tightening force applied by the operator. Insufficient force leads to leakage, while excessive tightening accelerates thread wear. Frequent friction causes the threads to strip. After the cap is closed, there are micro-gaps, from which volatile organic compounds (VOCs) escape. Utility Model Content
[0003] To address the aforementioned shortcomings, this utility model provides the following technical solution: A laboratory waste liquid collection tank includes a tank body with a groove on one side of the top of the tank body. A feed cylinder is located at the outer edge of the groove. A collection sleeve is sleeved on the outer side of the feed cylinder. A conical funnel is located on the inner side of the bottom end of the collection sleeve. A slot is located on one side of the top of the collection sleeve. A through groove is located on one side of the collection sleeve. A rotating shaft is located in the middle of the through groove and connects to the two sides of the cylinder wall. A crossbar is located on the rotating shaft. A conical plug is located at one end of the crossbar and a counterweight is located at the other end of the crossbar.
[0004] Furthermore, the feed cylinder is connected to the inside of the barrel, the outer side of the feed cylinder is provided with an external thread, and the bottom end of the collecting sleeve is provided with a thread corresponding to the external thread.
[0005] Furthermore, the shape of the conical plug matches the conical funnel and is arranged coaxially.
[0006] Furthermore, the conical plug is provided with a connecting line that connects to the bottom axis of the conical plug.
[0007] Furthermore, a slider is provided at one end of the crossbar, a counterweight is provided at the bottom of the slider, and a limiting block is provided at the tail end of the crossbar.
[0008] Furthermore, a guide tube is provided at the bottom of the conical funnel.
[0009] Furthermore, a handle is provided in the groove at the center of the top of the barrel.
[0010] The beneficial effects of this utility model are: 1. This utility model can avoid the need to unscrew the threaded cap every time waste liquid is poured, and to open and close the bucket cap multiple times, thus accumulating the effective working time; 2. This utility model can effectively prevent the sealing effect of the waste liquid bucket from depending entirely on the tightening force applied by the operator, which can easily lead to leakage if the force is insufficient. It can also prevent excessive tightening from accelerating thread wear and frequent friction from causing the thread to strip, and further prevent volatile organic compounds (VOCs) from escaping from the gaps.

[0013] 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.
[0014] Combination Figures 1 to 2 Shown: A laboratory waste liquid collection tank includes a tank body 1, which is rectangular. A groove 2 is provided on one side of the top of the tank body 1. A feed cylinder 3, i.e., the opening of the plastic tank, is provided on the outer side of the groove 2. A collection sleeve 4 is sleeved on the outer side of the feed cylinder 3 for collecting waste liquid. A conical funnel 5 is provided on the inner side of the bottom end of the collection sleeve 4. A guide tube 14 is provided at the bottom of the conical funnel 5. A flexible tube is sleeved on the guide tube 14 for further guiding the flow and facilitating the flow of waste liquid. A slot 6 is provided on one side of the top of the collection sleeve 4 for inserting a conventional funnel. A through groove 7 is provided on one side of the collection sleeve 4. A rotating shaft 8 is provided in the middle of the through groove 7 and connects to the two sides of the cylinder wall. A crossbar 9 is provided on the rotating shaft 8. A conical plug 10 is provided at one end of the crossbar 9 and a counterweight 11 is provided at the other end of the crossbar 9. The conical plug 10 is raised and lowered to seal the conical funnel through a lever structure.
[0015] The feed cylinder 3 is connected to the inside of the barrel 1. The feed cylinder 3 has an external thread on its outer side. The bottom end of the collecting sleeve 4 has a thread corresponding to the external thread. The collecting sleeve 4 can be fixed to the feed cylinder by the thread.
[0016] The conical plug 10 is shaped to fit the conical funnel 5 and is set along the same axis. A connecting line is provided on the conical plug 10 to connect to the bottom axis of the conical plug 10, which facilitates sealing the conical funnel 5. The material of the connecting line is selected as plastic or other components according to the actual situation.
[0017] A slider 12 is provided on one end of the crossbar 9, a counterweight 11 is provided at the bottom of the slider 12, and a limiting block 13 is provided at the tail end of the crossbar 9. The slider 12 moves on the crossbar 9 to adjust the center of gravity. The lever structure formed with the conical plug 5 and the crossbar 9 causes the conical plug to move up and down to open and close.
[0018] A handle 15 is provided in the groove 2 at the center of the top of the barrel 1 for carrying the waste liquid barrel.
[0019] Working principle: When using this utility model, the position of the counterweight is adjusted by moving the slider to raise the conical plug. The funnel is then inserted into the slot, and the waste liquid falls from the conical funnel. It is then guided directly through the guide tube or further guided to the bottom of the waste liquid tank by a corresponding hose. When not in use, the slider is moved closer to the feed cylinder. According to the lever principle, the conical plug descends and seals the conical funnel. After the waste liquid is full, the collection sleeve is unscrewed, and the waste liquid tank is sealed with the lid for transportation and disposal. The collection sleeve is then put on the next waste liquid tank for continued use.
