Description

Technical Field

[0001] This invention belongs to the field of pipette holder disinfection technology, specifically referring to a disinfection device for laboratory pipette holders. Background Technology

[0002] In precision experimental fields such as biology, chemistry, and medicine, pipette holders, as core auxiliary instruments supporting pipettes, directly affect the standardization of experimental procedures and the accuracy of experimental results. During use, the surface of pipette holders is easily contaminated with liquid sample residues, dust, and microorganisms. If disinfection is not thorough, cross-contamination can easily occur, interfering with the reliability of experimental data.

[0003] Current pipette stent sterilization devices on the market generally suffer from numerous technical defects, failing to meet the high-efficiency sterilization requirements of experimental scenarios: First, the sterilization coverage is limited, mostly employing a fixed-point spraying mode that cannot reach hidden areas such as stent gaps and corners, easily creating sterilization dead zones and resulting in incomplete sterilization; Second, there is a lack of dynamic auxiliary sterilization structures, with the stent undergoing sterilization in a static state, making it difficult to effectively remove stubborn contaminants adhering to the surface, significantly reducing the sterilization effect; Third, adaptability is poor, unable to flexibly adjust the bearing space according to the number and weight of stents, easily leading to stent stacking and compression during batch sterilization, further exacerbating the sterilization dead zone problem; Fourth, the operation process is cumbersome, with most devices requiring frequent manual adjustment of stent positions and control of sterilization rhythm, resulting in low automation, increasing the labor intensity of experimental personnel and reducing sterilization efficiency; Fifth, the structural design is unreasonable, with some devices being inconvenient to disassemble and assemble, hindering the handling of stents and the cleaning and maintenance of the device itself, affecting the hygiene of subsequent use.

[0004] To address the shortcomings of existing technologies, there is an urgent need to develop a laboratory pipette holder sterilization device that features dynamic assisted sterilization, strong adaptability, high automation, and convenient operation. This device would achieve comprehensive and efficient sterilization of the holder, ensuring the hygiene and safety of experimental procedures while maintaining efficiency. Summary of the Invention

[0005] In view of the above situation and to overcome the shortcomings of the prior art, the present invention provides a sterilization device for a laboratory pipette holder, which effectively solves the problems currently on the market.

[0006] The technical solution adopted by this invention is as follows: This invention proposes a sterilization device for a pipette holder used in experiments, including a device shell. A sliding groove is provided on the device shell. A reciprocating rod is provided at the top of the device shell, and one end of the reciprocating rod is placed in the sliding groove. A nozzle is provided on the reciprocating rod, and one end of the nozzle is connected to a water supply pipe. A drive motor is provided at one end of the reciprocating rod, and a drive gear is installed at the output end of the drive motor. A fixed rack is provided on the outer surface of the device shell, and a protective cover is provided on the outer surface of the device shell. A locking bolt connects the protective cover to the device shell.

[0007] Furthermore, a holding box is provided inside the outer shell of the device, and a lifting groove is provided on the side of the outer shell of the device. A telescopic spring is connected between the bottom surface of the holding box and the outer shell of the device. A second drive motor is provided on the protective cover. A drive shaft is connected to the output end of the second drive motor. A rotating block is connected to the end of the drive shaft away from the second drive motor. An extension block is provided on one side of the rotating block. An adjusting screw and a guide rod are connected between the rotating block and the extension block. A control block is provided on the adjusting screw.

[0008] Furthermore, one end of the reciprocating placement rod is slidably connected to the sliding groove, and the reciprocating placement rod is slidably connected to the top of the device housing, with the nozzles evenly distributed on the reciprocating placement rod.

[0009] Furthermore, the nozzle penetrates and is fixedly connected to the housing of the device, and one end of the water supply pipe is fixedly connected to the water inlet of the nozzle.

[0010] Furthermore, the drive motor is embedded in the other end of the reciprocating rod, the drive gear is fixedly connected to the output end of the drive motor, the fixed rack is fixedly connected to the housing of the device, and the drive gear meshes with the fixed rack.

[0011] Furthermore, the protective cover is detachable from the device housing via locking bolts, the container is slidably connected to the inside of the device housing, and one side of the container is slidably connected to the inside of the lifting groove.

[0012] Furthermore, one end of the telescopic spring is fixedly connected to the container, and the other end of the telescopic spring is fixedly connected to the outer shell of the device.

[0013] Furthermore, the second drive motor is fixedly connected to the protective cover, the drive shaft is fixedly connected to the output end of the second drive motor, and the rotating block is fixedly connected to the end of the drive shaft away from the second drive motor.

[0014] Furthermore, one end of the adjusting screw is rotatably connected to the extension block, the adjusting screw is threadedly connected to the adjusting screw, one end of the guide rod is fixedly connected to the extension block, and the other end of the guide rod is slidably connected to the rotating block.

[0015] Furthermore, the extension block abuts against the outer surface of the container, the control block is rotatably connected to the rotating block, and the control block is threadedly connected to the adjusting screw.

[0016] The beneficial effects achieved by the present invention using the above structure are as follows:

[0017] (1) This device constructs a dynamic bumping disinfection structure through the synergistic action of drive motor 2, drive shaft, rotating block, extension block and telescopic spring: when the extension block rotates, it pushes the container box downward to squeeze the telescopic spring. After separation, the container box bounces upward under the action of the spring force, causing the internal pipette support to bounce up and down and misalign. This can effectively remove stubborn contaminants from the surface of the support and break the limitations of static disinfection. At the same time, drive motor 1 drives the active gear to mesh with the fixed rack and drives the reciprocating placement rod to move back and forth along the sliding groove, so that the evenly distributed nozzles can spray disinfection on the support in the bumping state. The disinfectant can fully penetrate into the gaps, corners and other hidden parts of the support, completely eliminate disinfection dead corners and greatly improve the thoroughness of disinfection.

[0018] (2) The device provides elastic support to the container through a telescopic spring, which can automatically adjust the height of the container according to the number and weight of the pipette supports placed in, thus avoiding the stacking and squeezing of the supports. At the same time, by adjusting the screw of the control block, the distance between the rotating block and the extension block can be flexibly adjusted to match the actual position of the container after it carries the supports, ensuring that the bumping mechanism can stably drive the container to move. It can meet the disinfection requirements of different batches of supports without replacing the special support components, which greatly improves the device's adaptability and practicality.

[0029] like Figures 1-6 As shown, the present invention proposes a sterilization device for a pipette holder used in experiments, including a device housing 1, a sliding groove 2 on the device housing 1, a reciprocating rod 3 at the top of the device housing 1, one end of the reciprocating rod 3 being disposed in the sliding groove 2, a nozzle 4 on the reciprocating rod 3, one end of the nozzle 4 being connected to a water supply pipe 5, a drive motor 6 at one end of the reciprocating rod 3, a drive gear 7 installed at the output end of the drive motor 6, a fixing rack 8 on the outer surface of the device housing 1, a protective cover 9 on the outer surface of the device housing 1, and a locking bolt 10 connecting the protective cover 9 and the device housing 1.

[0030] The device housing 1 has a container 11 inside. The device housing 1 has a lifting groove 12 on its side. A telescopic spring 13 connects the bottom of the container 11 to the device housing 1. A second drive motor 14 is installed on the protective cover 9. The output end of the second drive motor 14 is connected to a drive shaft 15. A rotating block 16 is connected to the end of the drive shaft 15 away from the second drive motor 14. An extension block 17 is installed on one side of the rotating block 16. An adjusting screw 18 and a guide rod 19 are connected between the rotating block 16 and the extension block 17. A control block 20 is installed on the adjusting screw 18.

[0031] One end of the reciprocating rod 3 is slidably connected to the sliding groove 2, and the reciprocating rod 3 is slidably connected to the top of the device housing 1. The nozzles 4 are evenly distributed on the reciprocating rod 3.

[0032] The nozzle 4 penetrates and is fixedly connected to the housing 1 of the device, and one end of the water supply pipe 5 is fixedly connected to the water inlet of the nozzle 4.

[0033] The drive motor 6 is embedded in the other end of the reciprocating rod 3, the drive gear 7 is fixedly connected to the output end of the drive motor 6, and the fixed rack 8 is fixedly connected to the housing 1 of the device, and the drive gear 7 meshes with the fixed rack 8.

[0034] The protective cover 9 is detachable from the device housing 1 by means of the locking bolt 10. The container 11 is slidably connected to the inside of the device housing 1, and one side of the container 11 is slidably connected to the inside of the lifting groove 12.

[0035] One end of the telescopic spring 13 is fixedly connected to the container 11, and the other end of the telescopic spring 13 is fixedly connected to the outer shell 1 of the device.

[0036] The second drive motor 14 is fixedly connected to the protective cover 9, the drive shaft 15 is fixedly connected to the output end of the second drive motor 14, and the rotating block 16 is fixedly connected to the end of the drive shaft 15 away from the second drive motor 14.

[0037] One end of the adjusting screw 18 is rotatably connected to the extension block 17, and the adjusting screw 18 is threadedly connected to the adjusting screw 18.

Then, the protective cover 9 is reinstalled and fixed to the outer casing 1 of the device using the locking bolts 10. The second drive motor 14 is started, and the second drive motor 14 drives the rotating block 16 and the extension block 17 to rotate synchronously via the drive shaft 15. As the extension block 17 rotates, the container 11 moves downwards and compresses the telescopic spring 13. After the extension block 17 separates from the container 11, the container... Box 11 springs upward under the action of telescopic spring 13, causing the pipette holder inside box 11 to bounce and shift, allowing the pipette holder to be thoroughly cleaned. Water pipe 5 is connected to water pump, and water pump delivers cleaning liquid through water pipe 5 to nozzle 4, which is then sprayed out through nozzle 4. Drive motor 6 is started, and drive motor 6 switches between forward and reverse rotation at regular intervals, driving drive gear 7 to switch between forward and reverse rotation at regular intervals. Drive gear 7 meshes with fixed rack 8, and drive gear 7 drives reciprocating rod 3 to move back and forth at the top of device housing 1 under the action of fixed rack 8. The above is the overall working process of the present invention. This step can be repeated for the next use. The actual operation process is very simple and easy.
