Description

Technical Field

[0001] This utility model relates to the field of safety bottle cap technology, and in particular to a safety bottle cap for collecting laboratory waste liquid. Background Technology

[0002] In laboratory environments, instruments or routine experiments may generate toxic, harmful, and volatile waste liquids. These waste liquids cannot be directly discharged into municipal sewer systems; they must be collected in waste liquid containers for centralized, harmless treatment. To prevent the volatile liquids from evaporating and contaminating the laboratory environment, safety caps are required. These caps allow the waste liquid to enter the inner wall of the waste liquid container and prevent harmful substances from evaporating into the laboratory.

[0003] Safety bottle caps are typically provided with one inlet, one filter, and multiple spare connection holes. The spare connection holes are sealed with plugs. When multiple instruments need to be connected, the plugs need to be removed and infusion tubes need to be inserted into the spare holes. During this process, since the connection holes are always open to the outside, harmful substances in the volatile waste liquid can easily evaporate into the laboratory. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a safety cap for collecting laboratory waste liquid.

[0005] The technical solution of this utility model: A safety cap for collecting laboratory waste liquid, comprising a cap body, on which a liquid inlet and a filter are detachably installed, and further comprising:

[0006] Multiple connectors that can be detachably installed on the cover, wherein a connecting pipe can be detachably installed on each connector;

[0007] A first sealing mechanism is installed inside the connector, and the sealing state of the connector is controlled according to the connection state of the connector and the connecting pipe. A second sealing mechanism is installed inside the connecting pipe, and the second sealing mechanism controls the sealing state of the connecting pipe according to the connection state of the connector and the connecting pipe.

[0008] Optionally, the connector includes a fixed circular tube, and the first sealing mechanism includes a plurality of first support cylinders fixedly installed inside the circular tube. A first pressure plate is slidably installed inside the first support cylinder. A first connecting rod is fixedly installed on the first pressure plate. The first connecting rod passes through one side of the first support cylinder and extends to the outside of the first support cylinder. A first spring is fixedly installed on the first pressure plate, and the other end of the first spring is fixedly connected to the inner wall of the first support cylinder.

[0009] Optionally, a first sealing plate is fixedly installed on a plurality of the first connecting rods, a plurality of first guide rods are fixedly installed on the first sealing plate, and a pressure ring is fixedly installed on a plurality of the first guide rods.

[0010] Optionally, a plurality of first telescopic cylinders are fixedly installed on the pressure ring. The first telescopic cylinders cover the first guide rod inside, and the other end of the first telescopic cylinder is fixedly connected to the round tube.

[0011] Optionally, the connecting pipe includes a flexible hose, with a plurality of second support cylinders fixedly installed inside one end of the flexible hose. A second pressure plate is slidably installed inside the second support cylinder, and a second spring is fixedly installed on the second pressure plate. The other end of the second spring is fixedly connected to the inner wall of the second support cylinder. A second connecting rod is fixedly installed on the second pressure plate, and the second connecting rod passes through one side of the second support cylinder and extends to the outside of the second support cylinder.

[0012] Optionally, a second sealing plate is fixedly installed on a plurality of the second connecting rods, and a plurality of second guide rods are fixedly installed on the second sealing plate. The second guide rods pass through one side of the hose and extend to the outside of the hose.

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] like Figures 1 to 4 As shown, this utility model proposes a safety cap for collecting laboratory waste liquid, including a cap body 1. A liquid inlet 2 and a filter 3 are detachably installed on the cap body 1. Waste liquid is discharged into a waste liquid container through the liquid inlet 2. The liquid entering the waste liquid container will compress the gas inside the container. The compressed gas will be discharged through the filter 3. The filter 3 absorbs harmful substances in the waste liquid, ensuring that the gas in the laboratory is not contaminated and guaranteeing the safety of personnel inside the laboratory. The cap body 1 also includes multiple connectors 4 detachably installed, each connector 4 having a detachable connecting tube 5. When a new infusion tube needs to be added to the cap body 1, simply insert the connecting tube 5 into the connector 4 and connect the other end of the connecting tube 5 to the instrument at the waste liquid discharge end.

[0023] Furthermore, a first sealing mechanism is installed inside connector 4. This mechanism controls the sealing state of connector 4 based on the connection status between connector 4 and connecting pipe 5. When connecting pipe 5 is not connected to connector 4, connector 4 will not communicate with the outside, thus preventing the leakage of harmful gases. When connecting pipe 5 is connected to connector 4, connector 4 will automatically connect with connecting pipe 5, allowing waste liquid to effectively enter the waste liquid container. A second sealing mechanism is installed inside connecting pipe 5. This mechanism controls the sealing state of connecting pipe 5 based on the connection status between connector 4 and connecting pipe 5. When connecting pipe 5 is pulled out, it automatically seals the end of connecting pipe 5 near connector 4, effectively preventing any incompletely drained waste liquid from flowing out of connecting pipe 5 and preventing the presence of waste gas inside connecting pipe 5, thus discharging the waste gas into the laboratory environment.

[0024] In this embodiment, the connector 4 includes a fixed circular tube 401, and the first sealing mechanism includes multiple first support cylinders 402 fixedly installed inside the circular tube 401. A first pressure plate 403 is slidably installed inside the first support cylinder 402, and a first connecting rod 404 is fixedly installed on the first pressure plate 403. The first connecting rod 404 passes through one side of the first support cylinder 402 and extends to the outside of the first support cylinder 402. A first spring 405 is fixedly installed on the first pressure plate 403, and the other end of the first spring 405 is fixedly connected to the inner wall of the first support cylinder 402. Under the action of the first spring 405, a spring force will always be applied to the first pressure plate 403, and the first connecting rod 404 can move within a certain range when subjected to external force. When the external force disappears, the first connecting rod 404 will automatically reset. Furthermore, under the action of the first support cylinder 402, waste liquid will be prevented from directly contacting the first spring 405, effectively improving the service life of the first spring 405.

[0025] In this system, multiple first connecting rods 404 are fixedly mounted with first sealing plates 406, multiple first guide rods 407 are fixedly mounted on the first sealing plates 406, and pressure rings 408 are fixedly mounted on the multiple first guide rods 407. Under the action of a first spring, when the first guide rods 407 are not subjected to external force, the first sealing plates 406 will always abut against the circular tube 401, thus sealing the circular tube 401. Multiple first telescopic cylinders 409 are fixedly mounted on the pressure rings 408, and the first telescopic cylinders 409 enclose the first guide rods 407. The other end of the first telescopic cylinder 409 is fixedly connected to the circular tube 401. The first telescopic cylinders 409 can seal the space between the circular tube 401 and the first guide rods 407, preventing waste gas from escaping.

[0026] In this embodiment, the connecting pipe 5 includes a flexible hose 501. A plurality of second support cylinders 502 are fixedly installed inside one end of the flexible hose 501. A second pressure plate 503 is slidably installed inside the second support cylinder 502. A second spring 505 is fixedly installed on the second pressure plate 503. The other end of the second spring 505 is fixedly connected to the inner wall of the second support cylinder 502. A second connecting rod 504 is fixedly installed on the second pressure plate 503. The second connecting rod 504 passes through one side of the second support cylinder 502 and extends to the outside of the second support cylinder 502. Under the action of the second spring, a pushing force can be applied to the second connecting rod 504, allowing it to move within a certain range when affected by external force. When the external force disappears, the second connecting rod 504 will reset.

[0027] Furthermore, a second sealing plate 506 is fixedly installed on each of the multiple second connecting rods 504. Multiple second guide rods 507 are fixedly installed on the second sealing plate 506, passing through one side of the hose 501 and extending to the outside of the hose 501. Under the action of the second spring 505, the second sealing plate 506 will always abut against the hose 501, sealing the hose 501. When the second sealing plate 506 is pushed by an external force, it will separate from the hose 501, thereby allowing the hose 501 to connect with the outside world.

[0028] Multiple second telescopic cylinders 508 are fixedly installed on the flexible hose 501. The second telescopic cylinders 508 cover the second guide rod 507 and are fixedly connected to it. The gap between the second guide rod 507 and the second telescopic cylinder 508 can be sealed by the second telescopic cylinders 508.

[0029] Working principle: When connector 4 and connecting pipe 5 are connected, the second guide rod 507 will squeeze the pressure ring 408, and at the same time drive the first sealing plate 406 and the second sealing plate 506 to move. This can separate the first sealing plate 406 from the round pipe 401 and the second sealing plate 506 from the hose 501, thereby connecting connector 4 and connecting pipe 5. When connector 4 and connecting pipe 5 are separated, under the action of the first spring 405 and the second spring 505, the first sealing plate 406 and the second sealing plate 506 will respectively seal connector 4 and connecting pipe 5.

[0030] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
