[0042] The following is combined Figures 1-4 The technical solution of this utility model will be further illustrated through specific embodiments.

[0043] To prevent waste gas from harming the surrounding environment and the health of operators during the collection of waste liquid in experiments, and to ensure that the waste liquid collection has a liquid level alarm function, this utility model embodiment provides a waste liquid collection device. The device includes a collection container 1, a liquid inlet assembly 2, an alarm assembly 3, and a filter assembly 4. The collection container 1 has a liquid inlet 11 at its top. The liquid inlet assembly 2 includes a liquid inlet cap 21, a liquid inlet pipe 22, and a liquid inlet funnel 23. The liquid inlet cap 21 covers the liquid inlet 11, one end of the liquid inlet pipe 22 passes through the liquid inlet cap 21, and the other end of the liquid inlet pipe 22 is connected to the liquid inlet funnel 23. The alarm assembly 3 is located on the liquid inlet cap 21 and is used to monitor the liquid level of the waste liquid in the collection container 1 and issue an alarm signal. The filter assembly 4 is located on the liquid inlet cap 21 and is connected to the collection container 1. The filter assembly 4 is used to filter waste gas.

[0044] In detail, when using this device, the inlet cap 21 is placed over the inlet 11 of the collection container 1 to ensure the device's airtightness during waste liquid collection. At this time, the inlet funnel 23, the inlet pipe 22, and the collection container 1 are connected. Waste liquid is poured into the inlet funnel 23 and flows into the collection container 1 through the inlet pipe 22. The alarm component 3 detects the liquid level in the collection container 1. When the liquid level exceeds the set value, the alarm component 3 sounds an alarm, reminding the operator to stop pouring the waste liquid and replace the collection container 1. The above process is repeated until the batch of waste liquid is collected. The collected waste liquid is then transported to a designated location for centralized treatment. During the waste liquid pouring process, the waste gas is filtered by the filter component 4 into clean gas and discharged into the air. The device monitors the liquid level of the waste liquid by setting up an alarm component 3, which can remind the operator to handle the collection container 1 in a timely manner, thereby avoiding the harm to the environment and the health of the operator caused by the overflow of waste liquid; the filter component 4 can effectively adsorb harmful gases and odor molecules in the waste gas, avoiding the harm caused by the accumulation of waste gas; moreover, the device has a simple structure and is convenient for operators to use.

[0045] Furthermore, a funnel cover 231 is provided on the top of the inlet funnel 23. When waste liquid needs to be collected, the funnel cover 231 is opened and the waste liquid flows in through the inlet funnel 23. When the waste liquid is collected, the funnel cover 231 is placed on the top of the inlet funnel to prevent the inlet funnel 23 from being exposed to the air and foreign objects from entering the inside of the inlet funnel 23, which could cause the inlet funnel 23 to become blocked.

[0046] To facilitate the movement of the collection container 1 and allow the operator greater flexibility in collecting waste liquid, the waste liquid collection device also includes a collection platform 5. The collection container 1 is placed on the collection platform 5, and a steering component 6 is provided at the bottom of the collection platform 5. By placing the collection container 1 on the collection platform 5 and using the steering component 6, the collection container 1 can be moved to any location where waste liquid needs to be collected, thus facilitating the use of the device. In this embodiment, the workbench has a cuboid structure, the steering component 6 is a caster wheel, and four casters are respectively arranged at the four corners of the workbench.

[0047] Furthermore, the waste liquid collection device also includes a protective component 7, which is fixedly mounted on the collection platform 5. The protective component 7 is provided with a receiving cavity, and the collection container 1 is placed inside the receiving cavity. By fixing the protective component 7 to the collection platform 5 and placing the collection container 1 inside the receiving cavity of the protective component 7, the collection container 1 is prevented from slipping off the collection platform 5 during movement, thus preventing waste liquid from flowing out.

[0048] Optionally, the protective component 7 is provided with a protective cover 71, which covers the opening of the receiving cavity and is rotatably connected to one of the side walls of the receiving cavity. Further, the collecting container 1 is provided with a liquid inlet connector 12, which is located at and communicates with the liquid inlet 11. The protective cover 71 is provided with a through hole 711, which allows the liquid inlet connector 12 to pass through. When collecting waste liquid using this device, the protective cover 71 is flipped over to place the collecting container 1 into the receiving cavity, then the protective cover 71 is flipped over again to cover the opening of the receiving cavity, allowing the liquid inlet connector 12 to pass through the through hole 711. The liquid inlet cap 21 is then placed on the liquid inlet connector 12, allowing waste liquid to be poured into the liquid inlet funnel 23. The protective cover 71 prevents debris from entering the receiving cavity, keeping the inside of the device clean.

[0049] Furthermore, a buffer pad 9 is provided on the bottom wall of the receiving cavity, and the collection container 1 is placed on the buffer pad 9. The buffer pad 9 on the bottom wall of the receiving cavity effectively reduces shaking caused by uneven ground during device movement, preventing spillage of waste liquid from the collection container 1. In this embodiment, the buffer pad 9 is made of rubber, which increases the friction between the collection container 1 and the bottom wall of the receiving cavity, further reducing the sliding of the collection container 1, and thus reducing wear between the collection container 1 and the bottom wall of the receiving cavity.

[0050] Optionally, an observation port 72 is provided on one side of the protective component 7, through which the liquid level inside the collection container 1 and the condition of the waste liquid can be observed, further improving the practicality of the device.

[0051] refer to Figure 2 To further enhance the stability of the collection container 1 within the receiving cavity, the waste liquid collection device also includes a clamping assembly. This clamping assembly includes a clamping member 81, which is slidably disposed within the receiving cavity in a direction perpendicular to the side wall of the receiving cavity, thereby abutting against the outer wall of the collection container 1. The clamping member 81 is disposed within the receiving cavity and can slide in a direction perpendicular to the side wall of the receiving cavity, thus abutting against the outer wall of the collection container 1 and fixing the collection container 1 within the receiving cavity, ensuring the stability of the device during use.

[0052] Furthermore, the sidewall of the receiving cavity is provided with a sliding groove. The clamping assembly also includes a clamping seat 82, a connecting member 83, and an elastic member 84. The clamping seat 82 is located in the sliding groove, and the connecting member 83 is slidably disposed in the clamping seat 82. One end of the connecting member 83 is connected to the clamping member 81, and both ends of the elastic member 84 elastically abut against the clamping seat 82 and the other end of the connecting member 83, respectively. Specifically, a sliding groove is formed in the sidewall of the receiving cavity, the clamping seat 82 is embedded in the sliding groove, and a receiving groove is provided inside the clamping seat 82. One end of the elastic member 84 elastically abuts against the groove wall, one end of the connecting member 83 is disposed in the receiving groove and elastically abuts against the other end of the elastic member 84, and the other end of the connecting member 83 extends out of the receiving groove and is connected to the clamping member 81. The connecting member 83 can slide in the receiving groove. When using the clamping assembly to fix the collection container 1, the collection container 1 is placed inside the receiving cavity. At this time, the collection container 1 pushes the clamping member 81 to move away from the inside of the receiving cavity. The clamping member 81 drives the connecting member 83 to move, and the connecting member 83 compresses the elastic member 84. At the same time, the elastic member 84 applies a force in the opposite direction to the connecting member 83, thereby causing the clamping member 81 to abut against the outer wall of the collection container 1. The clamping member 81 clamps the collection container 1, thereby fixing the collection container 1 inside the receiving cavity. When it is necessary to replace the collection container 1, the collection container 1 is taken out from the receiving cavity. The force applied to the elastic member 84 disappears, and the connecting member 83 and the clamping member 81 move closer to the inside of the receiving cavity under the action of the elastic member 84.

[0053] In this embodiment, there are two sets of clamping components. The two sets of clamping components are set on two opposite side walls of the receiving cavity. Correspondingly, there are two sliding grooves. The collection container 1 is fixed by the two sets of clamping components, which further improves the stability of the collection container 1 during the movement process.

[0054] In some other embodiments, the number of clamping components can also be set to four sets, with the four sets of clamping components disposed on the four corresponding side walls of the two sets of receiving cavities. The number of clamping components can be set as needed and is not specifically limited here.

[0055] Furthermore, the connector 83 includes a first connecting portion 831 and a second connecting portion 832. The first connecting portion 831 is slidably disposed in the receiving groove and elastically abuts against the elastic member 84. The second connecting portion 832 extends out of the receiving groove and is connected to the clamping member 81. The first connecting portion 831 and the second connecting portion 832 are arranged perpendicularly. This arrangement simplifies the structure of the connector 83.

[0056] Optionally, in this embodiment, the elastic element 84 is a damping spring. The damping spring can ensure the stability of the collection container 1, thereby improving the stability of the entire device during use.

[0057] Furthermore, such as Figure 3As shown, the filter assembly 4 includes an inlet pipe 41, an outlet pipe 42, and a filter cover 43. One end of the inlet pipe 41 passes through the liquid inlet cap 21, and the other end is connected to one end of the outlet pipe 42. The other end of the outlet pipe 42 is connected to the filter cover 43, and a filter screen is installed inside the filter cover 43. Specifically, the inlet pipe 41 passes through the liquid inlet cap 21. The waste gas generated by the waste liquid flows from the inlet pipe 41 to the outlet pipe 42, and then flows into the filter cover 43 from the outlet pipe 42. The waste gas is filtered by the filter screen inside the filter cover 43. The filter screen can absorb harmful gases and odor molecules in the waste gas. Finally, the clean gas is discharged from the end of the filter cover 43 away from the outlet pipe 42 and released into the air, avoiding the accumulation of waste gas in the waste liquid and the harm of the waste liquid to the environment and operators.

[0058] Furthermore, multiple filters are provided, arranged sequentially along the direction away from the exhaust pipe 42. The multiple filters effectively absorb harmful gases in the exhaust gas, resulting in gas with higher purity. For example... Figure 4 As shown, in this embodiment, three filters are provided: a first filter 431, a second filter 432, and a third filter 433. The first filter 431 is located at the end of the filter cover 43 near the outlet pipe 42, and the third filter 433 is located at the end of the filter cover 43 away from the outlet pipe 42. The second filter 432 is located between the first filter 431 and the third filter 433. The mesh size of the first filter 431 is larger than that of the third filter 433, which is an activated carbon filter layer. That is, the exhaust gas passes through the first filter 431, where larger particles are filtered out. Then it passes through the second filter 432, where smaller particles are filtered out. After two filtrations, the exhaust gas flows to the activated carbon filter layer, where the activated carbon adsorbs harmful gases in the exhaust gas. Finally, the cleaned exhaust gas is discharged from the filter cover 43.

[0059] In this embodiment, a sealing element is provided at the connection between the air outlet pipe 42 and the filter cover 43. The sealing element can improve the sealing performance of the device, thereby reducing the leakage of waste gas during the waste liquid collection process.

[0060] Furthermore, such as Figure 1 As shown, the alarm component 3 includes a monitoring element 31 and an alarm element 32. The monitoring element 31 is disposed on the liquid inlet cover 21 and extends into the interior of the collection container 1. The alarm element 32 is disposed on the side of the liquid inlet cover 21 away from the monitoring element 31. The monitoring element 31 and the alarm element 32 are electrically connected. Specifically, the monitoring element 31 is disposed on one side of the liquid inlet cover 21 and extends into the collection container 1, while the alarm element 32 is disposed on the other side of the liquid inlet cover 21. First, the collection container 1 is set to a level at which waste liquid can be collected. The monitoring element 31 monitors the waste liquid level and transmits a signal to the alarm element 32. When the liquid level exceeds the set value, the alarm element 32 sounds an alarm, reminding the operator to stop pouring, thus ensuring the safety of the device during use.

[0061] In this embodiment, the monitoring component 31 is a liquid level sensor, and the alarm component 32 is an audible and visual warning light. The liquid level sensor and the audible and visual warning light are electrically connected. When the liquid level exceeds the set value, the audible and visual warning light can emit warning light and sound, providing better prompting to the operator. Both the liquid level sensor and the audible and visual warning light are existing technologies and will not be described in detail here.

[0062] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
