Double-cavity vacuum bottle

Abstract

The invention relates to a double-cavity vacuum bottle. The double-cavity vacuum bottle comprises a bottle body, a material pumping assembly and a bottle cap. The top of the bottle body is provided with a connecting external thread. The material pumping assembly comprises a connecting sleeve, a material pumping sleeve and a vacuum pump body, a sealing piston is arranged in the material pumping sleeve, the bottom of the sealing piston is provided with a mixed material opening, the mixed material opening is provided with a sealing film, and a tip end is arranged at the bottom of the vacuum pumpbody. When the sealing piston is in a lower limiting state, the tip end is located above the mixed material opening, and when the sealing piston is in an upper limiting state, the tip end penetrates the mixed material opening and is located below the mixed material opening. The connecting sleeve is provided with a connecting internal thread. According to the double-cavity vacuum bottle, part of materials are sealed in the material pumping sleeve through cooperation of the sealing piston and the material pumping sleeve, the sealing piston abuts against the top of the bottle body, so that in theprocess that the material pumping assembly is installed in the bottle body, the tip end ejects and pierces the sealing film, the materials in the material pumping sleeve enter the bottle body and aremixed with the materials in the bottle body, use is simple, customers purchase bottle bodies filled with different materials according to different requirements, and the use cost is reduced.
