Description

Technical Field

[0001] This utility model relates to the field of pipetting technology, and in particular to a convenient pipetting device. Background Technology

[0002] Pipettes are commonly used liquid transfer tools in laboratories, medical fields, and chemical industries. Their core function is to achieve precise extraction and transfer of liquids. Traditional pipettes are mostly fixed structures, with pipettes that cannot be folded or stored, taking up a lot of space when carried and making them inconvenient to move and use. At the same time, during liquid transfer, some viscous or sticky liquids tend to adhere to the inner wall of the pipette, resulting in liquid residue, affecting pipetting accuracy, and the residue is difficult to clean, reducing the efficiency of the device. Utility Model Content

[0003] This utility model relates to a convenient pipetting device that solves the problems of traditional pipetting devices being inconvenient to carry and prone to liquid residue.

[0004] This utility model provides a convenient pipetting device, specifically including: a mounting box; a handle is fixed on the mounting box, a peristaltic pump (model JSB310B) is installed inside the mounting box, a connecting tube is connected to the peristaltic pump, a battery for driving the peristaltic pump is installed inside the mounting box, a first switch for driving the peristaltic pump is fixed on the mounting box, and a cover plate is fixed inside the mounting box; two first connecting blocks are symmetrically fixed on the bottom end face of the mounting box, each first connecting block has a rotating shaft, the inner sides of the two rotating shafts are fixed to a pipette, and the connecting tube is connected to the pipette.

[0005] Furthermore, each shaft is fitted with an elastic pad, and each shaft is threaded with a locking nut. When the locking nut is tightened, the elastic pad comes into elastic contact with the straw, and the straw is stored after rotating 90 degrees.

[0006] Furthermore, the first connecting block, the rotating shaft, the suction tube, the elastic pad, and the locking nut together form the absorption part; a vibration motor is fixed on the suction tube, and the vibration motor is electrically connected to the battery in the mounting box. The vibration motor model is R-370, and a second switch for controlling the vibration motor is installed on the mounting box.

[0007] Furthermore, the mounting box is equipped with an auxiliary part, which consists of a slot, a second connecting block, a sliding seat, a spring rod, and a helical spring. The front and rear faces of the mounting box are provided with slots at equal intervals, and the slots are hemispherical groove structures.

[0008] Furthermore, two second connecting blocks are symmetrically fixed on the mounting box, and sliding seats are slidably mounted on the two second connecting blocks. Two spring rods are symmetrically fixed on the sliding seats, and the protruding ends of the two spring rods are both hemispherical structures, and the protruding ends of the two spring rods are both engaged in the slots.

[0009] Furthermore, two helical springs are sleeved on the sliding seat, and the helical springs serve as the rightward reset components of the sliding seat.

[0010] This invention provides a convenient pipetting device with the following advantages: The straw of the absorption section of this application can be rotated 90 degrees around the pivot to be stored. After tightening the locking nut, the elastic pad makes elastic contact with the straw to prevent it from automatically unfolding after storage, which greatly reduces the space occupied when carrying it. Combined with the handle on the installation box, it is convenient to move and carry.

[0011] During the pipetting process, the vibration motor is activated, and its vibration causes the liquid adhering to the inner wall of the pipette to fall off. At the same time, it pushes the sliding seat to make the spring rod continuously and elastically engage with the slot. This dual action reduces liquid residue and improves pipetting accuracy.

[0012] This application controls the peristaltic pump with a first switch and the vibration motor with a second switch, with a clear operating logic; each component has a compact structure, is easy to assemble, requires no complicated debugging, and is suitable for rapid pipetting operations in a variety of scenarios.

[0019] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0020] Example 1: Please refer to Figures 1 to 6 : This utility model proposes a convenient pipetting device, comprising: a mounting box 1; a handle 102 fixed on the mounting box 1; a peristaltic pump, model JSB310B, installed inside the mounting box 1; a connecting tube 103 connected to the peristaltic pump; a battery for driving the peristaltic pump installed inside the mounting box 1; a first switch 104 for driving the peristaltic pump fixed on the mounting box 1; and a cover plate 101 fixed inside the mounting box 1. Two first connecting blocks 201 are symmetrically fixed at the bottom end of the mounting box 1, each first connecting block 201 having a rotating shaft 202 rotatably mounted on it. The inner sides of both rotating shafts 202 are fixed to a pipette 203, and the connecting tube 103 is connected to the pipette 203. When carrying, rotating the pipette 203 rotates it 90 degrees, making it convenient to carry and reducing the space occupied during carrying.

[0021] Each rotating shaft 202 is fitted with an elastic pad 204, and each rotating shaft 202 is threaded with a locking nut 205. When the locking nut 205 is tightened, the elastic pad 204 comes into elastic contact with the straw 203. After the straw 203 is rotated 90 degrees to be stored, the elastic pad 204 can prevent the straw 203 from automatically unfolding.

[0022] The first connecting block 201, the rotating shaft 202, the straw 203, the elastic pad 204, and the locking nut 205 together form the absorption part 2. A vibration motor 3 is fixed on the straw 203. The vibration motor 3 is electrically connected to the battery in the mounting box 1. The vibration motor 3 is model R-370. A second switch 105 for controlling the vibration motor 3 is installed on the mounting box 1. When transferring liquid, the vibration motor 3 is started. The vibration of the vibration motor 3 can prevent liquid residue from remaining in the straw 203.

[0023] The mounting box 1 is equipped with an auxiliary part 4, which consists of a slot 401, a second connecting block 402, a sliding seat 403, a spring rod 404 and a coil spring 405. The front and rear faces of the mounting box 1 are provided with slots 401 at equal intervals. The slots 401 are hemispherical groove structures.

[0024] Among them, two second connecting blocks 402 are symmetrically fixed on the mounting box 1, and sliding seats 403 are slidably mounted on the two second connecting blocks 402. Two spring rods 404 are symmetrically fixed on the sliding seats 403. The protruding ends of the two spring rods 404 are hemispherical structures, and the protruding ends of the two spring rods 404 are engaged in the slots 401.

[0025] Example 2, based on Example 1, such as Figures 1 to 6As shown, two helical springs 405 are sleeved on the sliding seat 403. The helical springs 405 are the rightward reset components of the sliding seat 403. During use, the sliding seat 403 is pushed by hand. At this time, the spring rod 404 and the slot 401 are continuously and elastically engaged. Through the continuous elastic engagement between the two, the residue of liquid in the straw 203 can be reduced.

[0026] The working principle of this embodiment is as follows: Before use, loosen the locking nut 205, rotate the pipette 203 90 degrees from its stored state to the working position, and then tighten the locking nut 205 to fix the position of the pipette 203 by the elastic pad 204; insert the pipette 203 into the liquid to be transferred, press the first switch 104 to start the peristaltic pump, and draw liquid through the connecting tube 103 and the pipette 203 to complete the pipetting operation; during the pipetting process, press the second switch 105 to start the vibration motor 3, and use vibration to reduce the adhesion of liquid on the inner wall of the pipette 203; at the same time, the sliding seat 403 can be manually pushed so that the spring rod 404 continuously engages and slides in the slot 401, and the slight vibration generated by the sliding further cleans the residual liquid and improves the pipetting accuracy; after use, turn off the switch, loosen the locking nut 205, rotate the pipette 203 90 degrees to store it, tighten the locking nut 205 to fix it, and carry it through the handle 102 to complete the entire operation process.
