Description

Technical Field

[0001] This utility model relates to the field of pipette technology, specifically to a pipette for reagent testing that is easy to clean. Background Technology

[0002] Pipettes are particularly used in scientific and industrial laboratories, including in the medical, molecular biological, and pharmaceutical fields for measuring selected volumes of liquid. The liquid can be, in particular, a homogeneous (single-phase) liquid, consisting of a single liquid component or a homogeneous mixture of multiple liquid components (solutions). Furthermore, the liquid can be a heterogeneous (multiphase) mixture of one liquid with another liquid (emulsion) or solid (suspension).

[0003] However, existing pipettes are inconvenient to clean when drawing different reagents, and the cleaning effect is not good enough; therefore, they do not meet the current needs. In response, we propose a pipette for reagent testing that is easy to clean. Utility Model Content

[0004] The purpose of this invention is to provide a pipette for reagent testing that is easy to clean, in order to solve the problems mentioned in the background art, such as the inconvenience of cleaning the existing pipette when drawing different reagents, and the insufficient cleaning effect of the pipette.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pipette for reagent testing that is easy to clean, comprising a main body, an adjustment button at the upper end of the main body, a scale plate on the outer surface of the main body, a sleeve at the lower end of the main body, a pipette tip on the lower surface of the sleeve, a pipette head below the pipette tip, the pipette head and the pipette tip being connected by a connector, an inlet on the inner side of the pipette tip, a connecting groove on the inner wall of the inlet, a connecting sleeve on the inner side of the connecting groove, a handle at the upper end of the connecting sleeve, a liquid reservoir on the upper surface of the pipette tip, a connecting ring on the lower surface of the main body, an arc-shaped connecting piece on the outer surface of the connecting ring, the arc-shaped connecting piece being engaged with the sleeve by a positioning ball, and the lower end of the connecting ring being engaged with the pipette tip by a slot.

[0006] Preferably, the upper end of the liquid storage cylinder is inserted into the inner side of the main body, and a sealing strip is provided at the connection between the liquid storage cylinder and the main body.

[0007] Preferably, a sealing ring is provided between the lower end of the connecting ring and the inner wall of the slot.

[0008] Preferably, one side of the arc-shaped connecting piece is completely fitted with the outer surface of the connecting ring, and the arc-shaped connecting piece and the connecting ring are fixed by welding.

[0009] Preferably, the sleeve and the nozzle are integrally formed.

[0010] Preferably, the upper end of the connecting ring is completely fitted with the lower surface of the main body, and the connecting ring and the main body are fixed by welding.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model uses a connecting ring and an arc-shaped connecting piece on the lower surface of the main body. The arc-shaped connecting piece facilitates the snap-fit ​​between the main body and the sleeve. After the connection is completed, the lower end of the connecting ring is inserted into the slot. At this time, the liquid storage cylinder at the upper end of the suction nozzle is connected to the main body. When the device is transferring liquid, the inner wall of the connecting ring will not stick to the liquid. It is only necessary to disassemble the sleeve to clean the inner wall of the liquid storage cylinder, which reduces the cleaning difficulty for the staff.

[0013] 2. This utility model provides a connecting sleeve on the inner wall of the liquid inlet inside the suction nozzle. The connecting sleeve can be disassembled and replaced after use, reducing the need for workers to clean the liquid inlet, improving the cleaning speed of the device, reducing wear on the liquid inlet during cleaning, and extending the service life of the suction nozzle.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Please see Figures 1 to 3This utility model provides an embodiment of a pipette for reagent testing that is easy to clean, comprising a main body 2, an adjustment button 1 at the upper end of the main body 2, a scale plate 3 on the outer surface of the main body 2, a sleeve 4 at the lower end of the main body 2, a nozzle 5 on the lower surface of the sleeve 4, a pipette tip 6 below the nozzle 5, the pipette tip 6 and the nozzle 5 being connected by a connector 8, an inlet 7 on the inner side of the nozzle 5, a connecting groove 14 on the inner wall of the inlet 7, a connecting sleeve 15 on the inner side of the connecting groove 14, a handle 16 at the upper end of the connecting sleeve 15, a storage cylinder 13 on the upper surface of the nozzle 5, a connecting ring 9 on the lower surface of the main body 2, an arc-shaped connecting piece 11 on the outer surface of the connecting ring 9, the arc-shaped connecting piece 11 being engaged with the sleeve 4 by a positioning ball 12, and the lower end of the connecting ring 9 being engaged with the nozzle 5 by a slot 10.

[0020] The upper end of the liquid storage cylinder 13 is inserted into the inner side of the main body 2, and a sealing strip is provided at the connection between the liquid storage cylinder 13 and the main body 2, which increases the sealing performance of the connection between the liquid storage cylinder 13 and the main body 2.

[0021] A sealing ring is provided between the lower end of the connecting ring 9 and the inner wall of the slot 10, which increases the sealing performance of the connection of the connecting ring 9.

[0022] One side of the arc-shaped connecting piece 11 is completely fitted with the outer surface of the connecting ring 9. The arc-shaped connecting piece 11 and the connecting ring 9 are fixed by welding, which increases the working stability of the arc-shaped connecting piece 11.

[0023] The sleeve 4 and the nozzle 5 are integrally formed, which increases the working strength of the sleeve. The upper end of the connecting ring 9 is completely fitted with the lower surface of the main body 2. The connecting ring 9 and the main body 2 are fixed by welding, which increases the working effect of the connecting ring 9.

[0024] Working principle: During use, the connecting ring 9 and the arc-shaped connecting piece 11 set on the lower surface of the main body 2 facilitate the engagement between the main body 2 and the sleeve 4. After the connection is completed, the lower end of the connecting ring 9 is inserted into the slot 10. At this time, the liquid storage cylinder 13 at the upper end of the suction nozzle 5 is connected to the main body 2. When the device is transferring liquid, the inner wall of the connecting ring 9 will not stick to the liquid. Only the sleeve 4 needs to be disassembled to clean the inner wall of the liquid storage cylinder 13, which reduces the cleaning difficulty for the staff. By setting the connecting sleeve 15 on the inner wall of the liquid inlet 7 in the suction nozzle 5, the connecting sleeve 15 can be disassembled and replaced after use, reducing the cleaning of the liquid inlet 7 by the staff, improving the cleaning speed of the device, and reducing the wear of the liquid inlet 7 during cleaning, thus increasing the service life of the suction nozzle 5.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
