AI Technical Summary
Technical Problem
Existing pipettes put pressure on users' finger joints and muscles during frequent use, and electric pipettes increase the weight of the device, affecting users' health.
Method used
A pen-type electric pipette was designed, which adopts an ejection system and a flexible rod structure. The combination of the ejection rod and the ejection spring assists in the replacement of the pipette tip and reduces the pressure on the fingers. The combination of the pen tube structure and the vertical touch screen improves the ease of operation and comfort.
Benefits of technology
It reduces fatigue in users' finger joints and muscles, improves the efficiency and convenience of suction head replacement, reduces hand burden, and enhances the user experience.

Abstract
The application discloses a pen type electric pipette, which comprises a pipette shell, a pipetting system for controlling liquid in and out and a pushing system for assisting in pushing a suction head, the pipetting system comprises a pushing front end, a piston cylinder, a piston rod and a driving assembly for controlling the movement of the piston rod, the pushing system comprises a pushing rod for pushing the suction head, a pushing spring mounted on the pushing rod and a pop-up limiting assembly for locking the movement of the pushing rod, the pushing rod is an elastic rod with certain deformation capacity, and the pushing rod comprises a pressing part for pressing the suction head and a connecting rod part, an abutting table is fixedly connected to the inner wall of the pipette shell, at least one abutting part is fixedly connected to the connecting rod part, and the pushing spring is located between the abutting table and one of the abutting parts; without long pressing of a button, application of a larger force or maintenance for a longer time, the burden on the fingers of a user is reduced, the fatigue degree of the fingers of the user is reduced, and the health hidden danger of long-term use of the user is reduced.
