[0039] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0040] like Figure 1-11 The image shows a waste liquid recovery device according to this embodiment, suitable for centralized recovery of laboratory waste liquid. The waste liquid recovery device includes a main base 1, a bottle body 2, a liquid suction assembly 4, a vacuum pump 7, and a floating opening / closing component 6. The main base 1 has a insertion groove 11 machined on its top surface and a storage cavity 18 machined inside. A counterweight is arranged in the storage cavity 18 to increase the weight of the main base 1, allowing it to be stably placed on a flat surface. The lower end of the bottle body 2 is inserted into the insertion groove 11 to be placed on the main base 1. The outer diameter of the bottle body 2 is reasonably designed so that bottles of different volumes can be inserted into the insertion groove 11.

[0041] The bottle body 2 described above has a liquid collection chamber 25 inside, and two sets of connecting ports 23 are machined on the bottle body 2 to communicate with the liquid collection chamber 25. In a specific structural design, the bottle body 2 includes a bottle body 21 and a bottle cap 22 that are used in pairs. The bottle cap 22 is threadedly connected to the bottle body 21. Both of the above-mentioned connecting ports 23 are arranged on the bottle cap 22.

[0042] In this embodiment, the aforementioned floating opening / closing element 6 is arranged corresponding to at least one set of connecting ports 23. The number of floating opening / closing elements 6 is determined according to the actual structural design, and can correspond to two sets of connecting ports 23. The floating opening / closing element 6 is arranged in the liquid collection chamber 25 and can float up and down with the waste liquid in the liquid collection chamber 25. The floating opening / closing element 6 has an upward floating position that closes the connecting port 23 and a downward sinking position that moves away from the connecting port 23. In the upward floating position, it prevents waste liquid or gas from entering or leaving through the connecting port 23. In the downward sinking position, waste liquid or gas can pass through the connecting port 23. The aforementioned floating opening / closing element 6 is made of a plastic part with a cavity so that it can float up and down in the waste liquid.

[0043] In the specific structural design, an extension tube 24 extends from the connecting port 23 into the liquid collecting chamber 25. This extension tube 24 has an open end away from the connecting port 23. Several extended arms 61 are arranged at intervals along the circumferential direction on the aforementioned floating opening / closing member 6. Several protrusions are formed on each extended arm 61. Vertically extending grooves are machined on the outer wall of the extension tube corresponding to the extended arms 61. The extended arms 61 are arranged around the periphery of the extension tube, and the protrusions and grooves slide in cooperation, allowing the floating opening / closing member 6 to slide vertically on the extension tube, thereby switching between a submerged position and a floating position. When in the aforementioned floating position, the floating opening / closing member 6 seals the open end of the extension tube.

[0044] The aforementioned liquid aspiration assembly 4 includes a liquid aspiration tube 41 and a liquid aspiration nozzle 42. One end of the liquid aspiration tube 41 is connected to the first set of communication ports 23, and the other end of the liquid aspiration tube 41 is connected to the liquid aspiration nozzle 42. The liquid aspiration nozzle 42 has a conventional structure in the prior art. A locking structure 14 for locking the liquid aspiration nozzle 42 is machined on the main body base 1. The locking structure 14 is a groove structure adapted to the outer wall of the liquid aspiration nozzle 42. By locking the liquid aspiration nozzle 42 into the locking structure 14, the placement of the liquid aspiration nozzle 42 is facilitated, and contamination is prevented when placed on a flat surface.

[0045] In this embodiment, extension tubes 24 are arranged from the two sets of connecting ports 23. A height difference is formed between the open ends of the two sets of extension tubes. The suction tube 41 is connected to the connecting port 23 corresponding to the extension tube 24 that extends deeper into the collection chamber 25.

[0046] The aforementioned vacuum pump 7 is installed inside the storage cavity 18. A connecting nozzle 16 is arranged on the main unit base 1. One end of the vacuum pump 7 is connected to the connecting nozzle 16. The connecting nozzle 16 and the second set of communication ports 23 are connected by a connecting pipe 5. The connecting pipe 5 can be detached from the connecting nozzle 16 and the second set of communication ports 23. Through the operation of the vacuum pump 7, a negative pressure can be formed in the liquid collection chamber 25, thereby allowing waste liquid to be drawn through the suction nozzle 42 and transported into the liquid collection chamber 25.

[0047] In this embodiment, a controller and a battery unit are arranged inside the storage cavity 18. The aforementioned vacuum pump 7 and battery unit are respectively connected to the controller. The battery unit is used to supply power to the vacuum pump 7. A power adjustment unit 17 and a charging port 15 are installed on the main unit 1. The power adjustment unit 17 is connected to the controller to adjust the power of the vacuum pump 7. The battery unit can be charged through the charging port 15.

[0048] In this embodiment, the aforementioned bottle 2 is made of a light-transmitting material. An annular groove 12 is machined around the periphery of the insertion groove 11 on the top surface of the main unit 1. This annular groove 12 has a designed depth and is closed at the bottom. The waste liquid recovery device includes an ultraviolet (UV) device. The UV device includes a cover 3 and an UV generator installed inside the cover 3. The top of the cover 3 is closed, and the bottom is open. The cover 3 is made of polytetrafluoroethylene (PTFE). The UV generator is located at the top inside the cover 3 and emits UV light with a wavelength of 254 nm. This UV generator is a conventional component of the prior art. The cover 3 is inserted into the annular groove 12 and covers the bottle 2. The UV light emitted by the UV generator irradiates the bottle 2 and sterilizes the waste liquid in the collection chamber 25. A control switch for starting and stopping the UV generator is arranged on the main unit 1.

[0049] In this embodiment, a power-conducting connector 33 is installed on the outer wall of the housing 3. A power-conducting mating component 13 is installed on the main unit 1. The aforementioned power-conducting mating component 13 is connected to the battery unit via a wire. When the housing 3 is inserted into the annular groove 12, the power-conducting connector 33 and the power-conducting mating component 13 are interlocked and electrically connected, thereby enabling power to be supplied to the ultraviolet generator through the power-conducting connector 33 and the power-conducting mating component 13. The power-conducting connector 33 and the power-conducting mating component 13 are conventional components of the prior art. A wire-passing channel 32 is formed on the side wall of the housing 3. The wire-passing channel 32 extends in a predetermined direction. A wire is installed in the wire-passing channel 32. The first end of the wire is connected to the power-conducting connector 33, and the second end is connected to the ultraviolet generator.

[0050] In practical use, insert the pipette tip into the waste liquid. Start the vacuum pump 7, and the waste liquid is drawn into the bottle 2 through the suction tube 41. When the waste liquid in the bottle 2 reaches the preset level, the floating opening and closing component 6 closes the connecting port 23, thereby preventing the waste liquid from being drawn back into the vacuum pump 7 and reducing the risk of waste liquid contamination. The power of the vacuum pump 7 is adjusted by the power control unit to precisely control the suction speed and prevent waste liquid from remaining or splashing during the suction process. After the waste liquid is drawn, the pipette tip can be inserted into the locking structure 14 and placed upside down to prevent waste liquid from dripping from the pipette tip and causing secondary contamination. After disassembling the connecting tube 5 and the suction tube 41, or after removing the bottle cap 22, insert the cover 3 into the annular groove 12 to cover the bottle 2. The power connector 33 and the power mating component 13 are simultaneously inserted and connected. Start the ultraviolet generator to sterilize the waste liquid in the bottle 2. Among the above methods, waste liquid recycling and sterilization operations are convenient, time-saving, and labor-saving, effectively meeting the needs of centralized waste liquid recycling.
