Abstract

The invention discloses a simple automatic stop circuit of a blood centrifuge. The simple automatic stop circuit comprises a first fuse, a second fuse, a first single-pole switch, a second single-pole switch, a contactor, four resistors, a potentiometer, five capacitors, an LED, a voltage stabilizing diode, a first diode, a second diode, a motor and a time-base chip. A linked switch is combined by the first single-pole switch and the second single-pole switch. The first resistor, the first capacitor, the second capacitor, the first diode and the voltage stabilizing diode form a stabilizing rectifying circuit. An automatic stop control circuit is formed by the time-base chip, a relay, the third resistor and the third capacitor. According to the arrangement, fewer electronic elements are adopted, connecting manner of the whole circuit is simple, maintenance or changing of the electronic elements is facilitated, product cost is low, and market competitiveness of the product is high.

Description

technical field [0001] The invention relates to a self-stop circuit of a blood centrifuge, in particular to a simple self-stop circuit of a blood centrifuge. Background technique [0002] A blood centrifuge is a device that separates plasma and serum in the blood. The structure of the stop circuit of a general blood centrifuge is complex, and it is cumbersome to repair or replace its electronic components. Too many components make the product more expensive. Not conducive to competing in the market.
