AI Technical Summary

Technical Problem

Traditional cosmetic pumps lack a back-suction function, causing cosmetic residue to remain in the outlet pipe and become contaminated. Existing cosmetic pumps with back-suction function will suck contaminated cosmetic back into the cosmetic container, thus amplifying the contamination.

Method used

Design a dual-chamber back-suction cosmetic pump, including a back-suction chamber and a power chamber, connected by a power channel, equipped with an outlet valve, an inlet valve and a reset device, to achieve buffered back-suction of cosmetics and prevent the spread of contamination.

Benefits of technology

It effectively seals contaminated cosmetics in the return suction chamber, preventing the spread of contamination between the cosmetic container and the liquid outlet pipe, and ensuring the purity of the cosmetics.

Abstract

The utility model discloses a double-bin resorption cosmetic pump and a cosmetic container, in a liquid outlet state, a pressing interface enables the volumes of a resorption bin and a power bin to be compressed under the action of external force, so that cosmetics in the power bin enter the resorption bin through a power channel and then enter a liquid outlet channel through a liquid outlet valve; and in the reset state, under the action of the reset device, the volume of the resorption bin is expanded, so that the cosmetics in the liquid outlet channel are resorbed into the resorption bin through the liquid outlet valve, and the volume of the power bin is expanded, so that the cosmetics in the external cosmetic tank enter the power bin through the liquid inlet valve. The double-bin back-suction cosmetic pump can pump out the cosmetics in the cosmetic tank under the action of the pressing device, and can suck the residual cosmetics in the pressing device back into the double-bin back-suction cosmetic pump. The cosmetic pump is used as a buffer area between the cosmetic tank and the liquid outlet pipeline, and the polluted cosmetics are sealed in the buffer area, namely the polluted cosmetics are sealed in the back-suction bin, so that pollution expansion is avoided.
