Liquid storage part for electronic cigarette and electronic cigarette

The invention provides a liquid storage part for an electronic cigarette and the electronic cigarette, the liquid storage part is provided with a containing cavity used for containing tobacco tar, the containing cavity is provided with an outer wall forming an internal space and a liquid outlet allowing the tobacco tar to be led out, at least part of the outer wall comprises a flexible material, and the flexible material can deform along with flowing-out of the tobacco tar in the containing 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. 本发明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。本发明的储液部通过柔性材料的变形来压缩由于容纳腔中的烟油的流出所腾出的空间，从
