Description

Technical Field

[0001] The utility model belongs to the field of medical instruments, and particularly relates to an electric pipette gun. Background Art

[0002] A pipette gun is a type of pipettor, commonly used in laboratories for transferring small or trace amounts of liquid. Different specifications of pipette guns are equipped with different sizes of pipette tips. Although the shapes produced by different manufacturers are slightly different, their working principles and operating methods are basically the same. With the development of the times, electric pipette guns have gradually entered the market.

[0003] Most electric pipette guns on the market are placed with the handle perpendicular to the base when placed, causing the pipette tip of the electric pipette gun to face downward, which easily causes the excess liquid in the electric pipette gun to drip, resulting in contamination at the pipette tip and the operating table. Long-term contamination can easily affect the use environment of the electric pipette gun. Summary of the Invention

[0004] The purpose of the utility model is to provide an electric pipette gun for the above problems existing in the prior art.

[0005] The purpose of the utility model can be achieved by the following technical solutions: An electric pipette gun, comprising a pipette tip, a gun body, a handle, and a base. It is characterized in that two slot holes for fixing and limiting with the base are opened at the bottom of the handle, a charging hole for charging is opened between the slot holes, a receiving groove for receiving the handle is provided on the base, protrusions matching the slot holes are provided in the receiving groove, and a plug for supplying power to the charging hole is provided between the protrusions;

[0006] A mating part for placing in the receiving groove extends outward at the junction of the handle and the gun body, and a limiting band for fixing the mating part is provided on the inner wall of the receiving groove.

[0007] In the above-mentioned electric pipette gun, a number of operation buttons are provided on the gun body, and a display screen for displaying instructions and values is also provided on the gun body.

[0008] In the above-mentioned electric pipette gun, a power connection hole for connecting to a power source is provided on the outer side of the base.

[0009] Compared with the prior art, the electric pipette gun of the present utility model can be placed in two placement modes to meet different placement requirements. When the receiving groove cooperates with the mating part, the pipette tip is parallel to the operating table, reducing the dripping of liquid in the gun body. Brief Description of the Drawings

Specific embodiments

[0015] The following are specific embodiments of the present invention and in combination with the accompanying drawings, the technical solutions of the present invention will be further described, but the present invention is not limited to these embodiments.

[0016] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 shown, this electric pipette includes a pipette tip 1, a pipette body 2, a grip 3 and a base 4. Two slot holes 5 for fixing and limiting with the base 4 are opened at the bottom of the grip 3. A charging hole 6 for charging is opened between the slot holes 5. A storage groove 7 for storing the grip 3 is provided on the base 4. A protrusion 8 matching with the slot hole 5 is arranged in the storage groove 7. A plug 9 for supplying power to the charging hole 6 is arranged between the protrusions 8;

[0017] A mating part 10 for placing in the storage groove 7 extends outwards at the junction of the grip 3 and the pipette body 2. A limiting band 11 for fixing the mating part 10 is arranged on the inner wall of the storage groove 7.

[0018] A number of buttons 12 for operation are arranged on the pipette body 2. A display screen 13 for displaying instructions and values is also arranged on the pipette body 2. A power connection hole 14 for connecting to the power supply is arranged on the outside of the base 4.

[0019] Insert the slot holes 5 and the charging hole 6 at the bottom of the grip 3 into the protrusion 8 and the plug 9 respectively, so that the grip 3 is fixed in the storage groove 7. This operation is the placement method when charging this electric pipette;
