Description

Technical Field

[0001] This utility model relates to the field of waste collection technology, and in particular to a desktop waste collection device for PCR experiments. Background Technology

[0002] Polymerase chain reaction (PCR) is a molecular biology technique used to amplify specific DNA fragments. It can be seen as a special kind of DNA replication outside of living organisms. The biggest feature of PCR is that it can greatly increase a tiny amount of DNA. PCR experiments generate a lot of waste liquid, which needs to be collected.

[0003] Chinese Patent Publication No. CN221458766U discloses a PCR experimental waste liquid collection device with a barrel-shaped structure. The barrel is divided into upper and lower spaces by an isolation cover. The upper space is a waste collection chamber, and the lower space is a waste liquid collection chamber. The barrel cover has a waste disposal port. The isolation cover is connected to the barrel cover by a traction rope.

[0004] The aforementioned collection device is complicated to disassemble and inconvenient to clean due to the traction rope, and the discharge port cannot be closed. The evaporation of liquid inside the collection device can easily cause laboratory contamination. In addition, the bottom isolation cover and the collection bucket can slide, so their contact part cannot be sealed, and the waste liquid at the bottom is easy to evaporate and cause pollution. Therefore, we propose a desktop waste collection device for PCR experiments. Utility Model Content

[0034] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0035] Example 1: As Figures 1-12As shown, this embodiment provides a PCR laboratory desktop waste collection device, including a bucket body 1, a top cover 2 on the bucket body 1, a receiving groove 201, a round hole 202 and a plate opening groove 203 in the top cover 2, a plate opening cover 3 and an opening cover 4 in the receiving groove 201, a rotating sleeve 301 at both ends of the plate opening cover 3, and a rotating shaft 401 at both ends of the opening cover 4. The rotating sleeve 301 and the rotating shaft 401 are rotatably disposed in the receiving groove 201, and the rotating shaft 401 passes through the rotating sleeve 301.

[0036] The rotating sleeve 301 and the rotating shaft 401 are equipped with a reset component 5, and the barrel body 1 is equipped with a filter component 8; the upper cover 2 and the barrel body 1 form an integral seal, and the isolation cover 803 inside the barrel realizes solid-liquid separation and liquid sealing, and the upper cover 2 is equipped with a first handle 20.

[0037] The filter assembly 8 includes an isolation cover 801. The main body 1 of the tank is provided with a limiting surface, and the isolation cover 801 is provided on the limiting surface. The bottom surface of the isolation cover 801 is provided with a leaking nozzle 803. Next to the leaking nozzle 803 is a set of symmetrical sealing supports 804. The sealing supports 804 are provided with a sealing plate 805.

[0038] The main body of the barrel 1 has a sloping structure with a thicker bottom, which lowers the center of gravity and increases stability. The main body of the barrel 1 has a limiting surface that provides support for the isolation cover 801.

[0039] The isolation cover 801 is a cylindrical structure with a hole in the center. Placed on the limiting surface inside the container, it creates a cavity for the waste liquid. The top surface of the isolation cover 801 is a sloping surface inclined towards the central hole, facilitating the flow of waste liquid into the hole and into the waste liquid cavity. The isolation cover 801 has a handle 802 for easy removal to empty the cleaning waste liquid. The bottom surface of the isolation cover 801 has a drain nozzle 803, a tubular structure connected to the hole in the isolation cover 801 at the top, allowing waste liquid to flow through the hole and into the drain nozzle 803.

[0040] Next to the leak nozzle 803 is a set of symmetrical column structures. The top of each column is circular with a small hole in the center, serving as a sealing support 804. A sealing plate 805 is located between the sealing supports 804, fixed to the circular hole in the sealing support 804 via a symmetrical cylindrical structure in the center. The sealing plate 805 can rotate due to its cylindrical structure. Because of a counterweight at its tail, the sealing plate 805 can cover the small hole of the leak nozzle 803 when no liquid is flowing out, achieving the purpose of sealing the waste liquid chamber. When liquid flows out of the leak nozzle 803, the head of the sealing plate 805 descends due to gravity, exposing the small hole of the leak nozzle 803, and the liquid flows into the waste liquid chamber. This design features solid-liquid separation, strong sealing performance, easy disassembly and cleaning, and good stability.

[0041] A clearance groove 101 is provided on one side of the barrel body 1. Two sets of pedals 6 are rotatably installed in the clearance groove 101. A transmission assembly 7 is provided between the pedals 6, the rotating sleeve 301, and the rotating shaft 401.

[0042] The transmission assembly 7 includes: a first groove 102, which is formed inside the barrel body 1; a second groove 204, which is formed inside the upper cover 2; two rotating rods a701, which are rotatably disposed in the first groove 102; a gear a702, which is mounted on the rotating rods a701, and a reset assembly 5 is provided on the rotating rods a701; and a swing rod a703, which is mounted on the rotating rods a701.

[0047] Cleaning: Remove the top cover 2, take out the isolation cover 801, and rinse.

[0048] The waste liquid chamber has an automatic sealing structure to achieve solid-liquid separation. The two closable inlet ports in the top cover 2 can reduce pollution. The interior of the main body 1 is sloping and has a heavy bottom, making it more stable on the table.

[0049] Regarding the opening of orifice cover 4 and plate cover 3:

[0050] When the top cover 2 is placed on the upper part of the barrel body 1 (which can be detached by bolts), gears a702 and b706 mesh. Without the action of external force, the elastic torque of the elastic connector 501 drives the rotating sleeve 301 and the rotating shaft 401 to rotate, driving the plate opening cover 3 to seal the plate opening groove 203 and driving the hole opening cover 4 to seal the round hole 202.

[0051] When it is necessary to open the slot 203, stepping on a pedal 6 pulls the rope a704 to drive the swing rod a703 to swing and drive the rotating rod a701 to rotate. Through gears a702 and b706, the rotating rod b705 is driven to rotate. Through the rope b709, the swing rod b707 is pulled to swing, driving the rotating sleeve 301 to rotate, and driving the slot cover 3 to rotate to open the slot 203.

[0052] When it is necessary to open the round hole 202, by stepping on another pedal 6, the rope a704 is pulled to drive the swing rod a703 to swing and drive the rotating rod a701 to rotate. Through gears a702 and b706, the rotating rod b705 is driven to rotate. Through the rope c710, the swing rod c708 is pulled to swing, driving the rotating shaft 401 to rotate, and driving the hole cover 4 to rotate and open the round hole 202.

[0053] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
