Dropper distributor of telescopic pipette

Abstract

The invention discloses a dropper distributor of a telescopic pipette. The dropper distributor of the telescopic pipette comprises a containing jar mounted in a mouth of a bottle in an insertion mode, a large piston, a spring, a small piston and the pipette are arranged in the containing jar from top to bottom in sequence, a fixing lock is arranged on the top of the containing jar, the large piston is connected in the containing jar in a sliding mode, and the large piston is provided with an inner cavity with a downward opening. The upper portion of the small piston is arranged in the inner cavity of the large piston in an insertion mode, and the large piston and the small piston are in sliding connection. The spring is clamped and pressed between the small piston and the large piston. The top of the pipette is connected with the lower portion of the containing jar in a sliding mode. The lower end of the small piston is connected to the pipette in a pressing mode, and an imbibition nozzle of the pipette makes contact with the bottom of the bottle. A nut is connected to the large piston in a pressing mode, the nut is connected with the neck of the bottle through threads, an outer sleeve is arranged on the nut, the outer sleeve is fixed to the containing jar, and the nut is connected to the outer sleeve in circumferential static and axial sliding mode. According to the dropper distributor of the telescopic pipette, it can be ensured that the pipette is not broken off or bent, and the imbibition nozzle of the pipette can stay at the lowermost part of a container.

Description

technical field [0001] The invention relates to a solution dispensing device, in particular to a dropper dispenser of a retractable suction pipe. Background technique [0002] At present, the dropper dispenser for the container sold on the market, due to the dimensional tolerance of the parts during production, the suction tube is too long or the height of the container is insufficient, which causes the suction tube to bend or break. In actual production, in order to avoid the above situation, the producer needs to deliberately design the suction tube above the bottom of the container so that there is a certain distance between the suction tube and the bottom of the container. This intentionally shortens the suction tube , It is inevitable that the pipette cannot touch part of the bottommost liquid, and the untouched valuable content cannot be sucked out. In summary, if the suction tube cannot touch the bottom of the bottle, the content at the bottom of the bottle cannot be...

AI Technical Summary

Problems solved by technology

To sum up, if the pipette cannot touch the bottom of the bottle, the contents of the bottom of the bottle cannot be sucked, resulting in waste; excessive contact will break the pipette or cause the pipette to bend in the bottle
