E-cigarette

Abstract

The present invention provides an e-cigarette including a housing body with a smoking mouth, an atomizer accommodated in the housing body, a smoke chamber disposed between the atomizer and the smoke mouth, a first containment cavity, and a MEMS sensor. The housing body is provided with a first through hole that is connected with the outside world and the MEMS sensor. The MEMS sensor includes a printed circuit board, a first housing, and a MEMS chip and an ASIC chip placed in the second containment cavity. The MEMS sensor further includes a second housing connected to the printed circuit board. The first housing and the second housing are spaced to form a third containment cavity. A gap connecting the first containment cavity and the third containment cavity is provided between the second housing and the printed circuit board. The e-cigarette can protect the MEMS sensor.

What is claimed is: 
     
         1 . An e-cigarette, comprising;
 a housing body having a smoking mouth and a first through hole;   an atomizer accommodated in the housing body and defining a distance from the smoking mouth;   a smoke chamber arranged between the atomizer and the smoking mouth;   a first containment cavity connected with the smoking mouth;   a MEMS sensor placed in the first containment cavity for communicating with outside via the first through hole; wherein
 the MEMS sensor includes a printed circuit board, a first housing connected to the printed circuit board for forming a second containment cavity, a MEMS chip and an ASIC chip placed in the second containment cavity; and wherein
 the MEMS sensor further includes a second housing that covers the first housing and is connected to the printed circuit board, the first housing and the second housing are spaced to form a third containment cavity, a gap connecting the first containment cavity and the third containment cavity is provided between the second housing and the printed circuit board.
