Technical Field

[0001] This utility model relates to the field of experimental detection technology, specifically a portable micropipette. Background Technology

[0002] A micropipette is a precision liquid-taking device that can be adjusted within a certain capacity range.

Micropipettes are also used to assist in the detection of agricultural product test solutions.

[0003] However, existing micropipettes still have some problems in use:

[0004] First, the lack of integrated pipette tip storage means that in actual use, different experimental scenarios require different specifications of pipette tips, so users have to carry an extra pipette tip box or loose pipette tips, which increases the burden of carrying them and thus reduces the portability of the pipette.

[0005] Secondly, existing micropipettes are generally used by pressing or pulling to aspirate and dispense liquid. This pressing method cannot accurately control the liquid volume, thus reducing the accuracy of the pipette volume adjustment. Utility Model Content

[0006] To address the problem that existing pipette structures lack an effective tip storage box and cannot accurately control the pipetting volume, the purpose of this invention is to provide a portable micropipettes.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example: Figure 1-4 As shown, this utility model provides a portable micropipette, including a pipette 1. A handle 5 is fixedly installed on the outer surface of the pipette 1, which makes it easier for the user to hold the pipette 1 and makes the operation more stable. The pipette 1 is a transparent tube, which allows the user to observe the liquid inside. A pipette tip 4 is threadedly connected to the lower surface of the pipette 1. The pipette tip 4 is threadedly connected to the lower surface of the pipette 1, which is a firm connection and easy to disassemble and replace. The inner and outer surfaces of the pipette 1 are provided with a volume control component 3. The outer surface of the pipette 1 is provided with a portable storage component 2 for use with the pipette tip 4. The setting of the volume control component 3 and the portable storage component 2 respectively realizes precise volume adjustment and convenient storage of the pipette tip 4, improving the overall practicality and convenience of the pipette.

[0020] The portable storage component 2 includes a storage box 21, which is fixedly installed on the outer surface of the pipette 1. The storage box 21 is fixed to the outer surface of the pipette 1 to achieve integrated storage of the pipette tip 4, eliminating the need to carry an additional box for holding the pipette tip 4. A sealing cover 22 is hinged to one side of the storage box 21, and one side of the sealing cover 22 is magnetically connected to the storage box 21. The sealing cover 22 is connected to the storage box 21 by hinge and magnetic attraction, which is convenient to open and close and has good sealing performance, preventing the pipette tip 4 from falling off or becoming contaminated.

[0021] The storage box 21 has a card holder 23 fixedly installed inside in parallel. One side of the card holder 23 has a slot 24 for use with the pipette tip 4. The pipette tip 4 is movably engaged inside the slot 24. The design of the card holder 23 and the slot 24 can stably engage the pipette tip 4, making it easy to quickly retrieve and effectively improving the convenience of using the pipette.

[0022] The liquid volume control component 3 includes a positioning plate 33, which is fixedly installed inside the pipette 1. The positioning plate 33 has a threaded groove 38 inside, and a screw 32 is threadedly connected inside the threaded groove 38. An anti-slip knob 31 is fixedly connected to the top of the screw 32. The positioning plate 33 and its threaded groove 38 provide a stable transmission structure for the screw 32. The user rotates the anti-slip knob 31 to drive the screw 32 to rotate. Compared with the traditional pressing method, the rotation amplitude of the screw 32 can be controlled more accurately, thereby precisely adjusting the movement stroke of the piston head body 35. A connecting post 34 is fixedly connected to the bottom of the screw 32. The piston head body 35 is slidably connected inside the pipette 1. The piston head body 35 slides and engages with the inside of the pipette 1, achieving precise liquid aspiration and dispensing under the drive of the screw 32.

[0023] The outer surface of the pipette 1 is provided with scale lines 39 that are used in conjunction with the piston head body 35. The scale lines 39, in conjunction with the piston head body 35, can intuitively display the volume of liquid being pipetted, making it convenient for users to observe and control. A circular plate 36 is fixedly connected to the upper surface of the piston head body 35, and a positioning seat 37 is fixedly connected to the upper surface of the circular plate 36. The connecting column 34 is internally damped and rotatably connected to the positioning seat 37. The damped rotatable connection between the connecting column 34 and the positioning seat 37 ensures that the piston head body 35 rises and falls stably when the screw 32 rotates, which significantly improves the accuracy of the pipette volume adjustment.

[0024] Working principle: First, before use, the pipette tip 4 is snapped into the slot 24 of the portable storage component 2. The storage box 21 is fixed to the outer surface of the pipette 1, and the holder 23 and the slot 24 provide a stable place for the pipette tip 4.

[0025] The sealing cap 22 is connected to the storage box 21 by hinge and magnetic attraction. When closed, it can prevent the pipette tip 4 from falling off or getting contaminated. When in use, open the sealing cap 22, take out the pipette tip 4 from the slot 24, and screw it onto the lower surface of the pipette 1 by rotating and tightening. Then you can start the pipetting operation.

[0026] During pipetting, the user holds the handle 5 through the liquid volume control component 3 and rotates the anti-slip knob 31 to drive the screw 32 to rotate. The screw 32 cooperates with the threaded groove 38 inside the positioning plate 33 to convert the rotational motion into linear motion.

[0027] The connecting post 34 at the bottom of the screw 32 is damped and rotatedly connected to the positioning seat 37 on the piston head body 35, so that when the screw 32 rotates, the piston head body 35 can slide stably up and down inside the pipette 1, thereby changing the volume inside the pipette 1. The damped rotational connection between the connecting post 34 and the positioning seat 37 can prevent the piston head body 35 from rotating with the screw 32, ensuring that the rotational motion of the screw 32 is only converted into the vertical sliding of the piston head body 35, thereby achieving stable volume control.

[0028] The transparent pipette 1 has graduated lines 39 on its outer surface, which cooperate with the piston head body 35, allowing the user to directly observe and control the pipetting volume.

[0029] When aspirating liquid, rotate the anti-slip knob 31 upwards. The screw 32 drives the piston head body 35 to move upwards, reducing the air pressure inside the pipette 1. The liquid is then drawn into the pipette 1 through the pipette tip 4. When discharging liquid, rotate the anti-slip knob 31 downwards. The piston head body 35 moves downwards, increasing the air pressure inside the pipette 1. The liquid is then discharged through the pipette tip 4, completing precise pipetting.

[0030] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
