Liquid storage part for electronic cigarette and electronic cigarette

The utility model provides a liquid storage portion for electronic cigarette and electronic cigarette wherein the liquid storage portion is provided with an accommodation cavity for accommodating tobacco tar, the accommodation cavity is provided with an outer wall forming an internal space and a liquid outlet for leading out the tobacco tar, the outer wall at least partially comprises a flexible material, and the flexible material can deform along with the outflow of the tobacco tar in the accommodation cavity. And the volume of the accommodating cavity is correspondingly reduced. The liquid storage part compresses the space vacated by the outflow of the tobacco tar in the accommodating cavity through the deformation of the flexible material, so that the pressure difference caused by the outflow of the tobacco tar is balanced, and the leakage of the tobacco tar is avoided. 本实用新型提供一种电子烟用储液部以及电子烟，其中，储液部具有用于容纳烟油的容纳腔，容纳腔具有形成内部空间的外壁和供烟油导出的出液口，外壁至少部分包括柔性材料，柔性材料可随位于容纳腔内的烟油的流出而变形，使得容纳腔的容积相应变小。本实用新型的储液部通过柔性材料的变形来压缩由于容
