The present invention relates to the technical field of an electronic cigarette and, more specifically, to an electronic cigarette
Because electronic cigarettes do not have tar, suspended particles and other harmful components, they have a wide range of application markets. The existing electronic cigarette usually comprises a shell, a liquid storage bin, atomizing core, a battery, an airflow sensor and a controller, a top of the shell is connected with a suction nozzle, a bottom of the shell is provided with an intake hole, the liquid storage bin is located in the shell, the liquid storage bin is used to store cigarette liquid, the atomizing core is located in the liquid storage bin and connected with the suction nozzle. The airflow sensor is located at the bottom of the shell and is used to detect whether a user is smoking.
When the user smokes, the airflow sensor senses that the user smokes and triggers the controller, the controller controls the battery to supply power to the atomizing core, and the atomizing core atomizes the cigarette liquid to form smoke for the user to smoke. However, due to the airflow sensor is far away from the suction nozzle, when smoking, the airflow sensor is triggered only after air in the suction nozzle and liquid storage bin is sucked, so the sensitivity is low and the taste is poor.
The present invention aims to provide an electronic cigarette which can improve the sensitivity and the taste.
A solution of the present invention to solve the above problem is as follows: an electronic cigarette is constructed, wherein the electronic cigarette comprises a shell, a suction nozzle, a liquid storage tube, an elastic sealing seat, an atomizing core and an airflow sensor, wherein the shell is provided with an accommodating cavity; the suction nozzle is connected with the shell, and the liquid storage tube is located in the accommodating cavity; a first end of the elastic sealing seat covers a tube mouth of the liquid storage tube facing the suction nozzle, and is provided with a smoke exhaust hole connected with the suction nozzle, and a second end of the elastic sealing seat is provided with a mounting slot, and the mounting slot is arranged in parallel with the smoke exhaust hole in a spaced manner; the atomizing core is located in the liquid storage tube and communicated with the smoke exhaust hole; and the airflow sensor is located in the mounting slot.
The present invention has the following beneficial effects: as the first end of the elastic sealing seat covers the tube mouth of the liquid storage tube facing the suction nozzle, and is provided with the smoke exhaust hole connected with the suction nozzle, and the second end of the elastic sealing seat is provided with the mounting slot; the atomizing core is located in the liquid storage tube and communicated with the smoke exhaust hole; and the airflow sensor is located in the mounting slot. Therefore, the airflow sensor is close to a sucking part, which can improve the sensitivity of smoking and obtain greater smoke concentration and better taste. In addition, because the mounting slot is arranged in parallel with the smoke exhaust hole in a spaced manner, the problem of short service life is avoided when the airflow sensor is located at the bottom of the shell in relative technology, which is easy to be polluted by the leaked cigarette liquid.
