Electronic cigarette comprising one-way valve
View Patent ↗An electronic cigarette, including an air passage and a one-way valve disposed in the air passage. The one-way valve includes a soft material. When in use, a forward airflow is passable through the one-way valve, and a reverse airflow is unpassable through the one-way valve, thus preventing the reverse airflow or saliva from entering the atomizer of the electronic cigarette.
1. An electronic cigarette, comprising a mouthpiece, a base, an atomizing core, a glass tube, a battery, and a one-way valve; wherein
the glass tube is disposed on the battery, and is configured to store e-liquid;
the atomizing core is disposed in the glass tube;
the one-way valve is disposed in a cavity of the mouthpiece;
the one-way valve comprises a silicone material or a latex material; when in use, a forward airflow is passable through the one-way valve, and a reverse airflow is unpassable through the one-way valve, thus preventing the reverse airflow or saliva from entering the atomizer core of the electronic cigarette;
the mouthpiece is disposed on and is in threaded connection to the base; and
the base comprises a first tube and a second tube; the first tube is disposed inside the one-way valve; the second tube extends into the atomizing core; and an inner space of the first tube communicates with an inner space of the second tube.
2. The electronic cigarette of claim 1 , wherein the one-way valve comprises a slot; the slot is configured to allow the forward airflow to pass through.
3. The electronic cigarette of claim 2 , wherein the forward airflow enters the one-way valve and flows out from the slot when in use.
4. The electronic cigarette of claim 3 , wherein when an airflow enters the one-way valve, the slot is automatically closed, so that the airflow is unpassable through the one-way valve.
