Abstract
A fluid delivery device, comprising an integrated cabinet, a pump installed in the integrated cabinet, an inlet pipeline connected to the pump, and an outlet pipeline connected to the pump; the pump comprises a motor located at the bottom portion of the integrated cabinet, a pump head located at the top portion of the integrated cabinet, and a magnetic coupling portion located between the motor and the pump head; the pump head, the magnetic coupling portion and the motor are arranged in a sequence from top to bottom; and the pump head is provided with a U-shaped flow channel and a gear mechanism therein located at the bottommost portion of the flow channel. The fluid delivery device eliminates bubbles in the solution accumulated in the pump, thus ensuring a working efficiency of fluid delivery of the pump, and ensuring precise control of a delivery amount.
