The disclosure relates to an electronic cigarette comprising a one-way valve.

Conventionally, when a user blows the air into the air passage of an electronic cigarette, the air will enter the atomizer and squeeze out the e-liquid, thus staining the electronic cigarette.

The disclosure provides an electronic cigarette, comprising an air passage and a one-way valve disposed in the air passage; the one-way valve comprises 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 an atomizer of the electronic cigarette.

In a class of this embodiment, the one-way valve comprises an upper part and a lower part; the lower part is a hollow cylinder and a lower edge of the hollow cylinder comprises an inner protrusion along a radial direction of the hollow cylinder.

In a class of this embodiment, the upper part is an inverted V-shape and comprises a first end fixedly disposed on the lower part and a second end comprising a slot; the slot is configured to allow the forward airflow to pass through.

In a class of this embodiment, the one-way valve comprises environmentally friendly soft silicone material or soft latex material.

In a class of this embodiment, the forward airflow enters the hollow cylinder of the one-way valve and flows out from the slot. when an airflow enters the one-way valve from the upper part thereof, the slot is automatically closed, so that the airflow is unpassable through the one-way valve.

To further illustrate, embodiments detailing a one-way valve are described below. It should be noted that the following embodiments are intended to describe and not to limit the disclosure.

As shown in FIGS. 1 - 5 B , the disclosure provides an electronic cigarette comprising a mouthpiece 1 , a one-way valve 2 , a first seal ring 3 , a base 4 , an atomizing core 5 , a glass tube 6 , a second seal ring 7 , and a battery 8 . The top end of the battery comprises a screw thread. The atomizing core 5 is fixedly disposed on the top end of the battery through the screw thread. The glass tube 6 abuts against the top end of the battery. The atomizing core 5 is disposed in the glass tube 6 . The glass tube 6 is configured to store e-liquid. The second seal ring 7 is disposed between the screw thread of the battery 8 and the bottom opening of the glass tube 6 to seal the bottom opening. The upper part of the base 4 is disposed in the top opening of the glass tube 6 and the lower part of the base 4 is in threaded connection to the top end of the atomizing core 5 . As shown in FIG. 3 , the base 4 comprises a first tube 4 - 1 disposed inside the one-way valve 2 and a second tube 4 - 2 extending into the atomizing core 5 and communicating with the first tube 4 - 1 . The first seal ring 3 is disposed between the upper part of the base 4 and the top opening of the glass tube 6 to seal the top opening. The one-way valve 2 is disposed in the cavity of the mouthpiece 1 to prevent the reverse air from the mouthpiece 1 from entering the glass tube 6 to extrude the e-liquid and guide the reverse air out of the mouthpiece. The mouthpiece 1 is in threaded connection to the base 4 .

In certain embodiments, as shown in FIG. 6 , the one-way valve is disposed in an electronic hookah. Specifically, the electronic hookah comprises an air passage 10 and a water channel 9 . The one-way valve is disposed between the air passage and the water channel. The vapor passes through the air passage with the forward air flow, through the one-way valve 2 , and then enters the water channel. When the one-way valve 2 is squeezed by water in the water channel, the slot 2 - 1 of the one-way valve 2 is closed automatically, so that the water cannot enter the air passage through the one-way valve 2 .

The following advantages are associated with the electronic cigarette of the disclosure:

1. The electronic cigarette comprises a one-way valve, which can prevent the reverse airflow from entering the e-cigarette to squeeze out the e-liquid. 2. The one-way valve comprises environmentally friendly soft silicone material or soft latex material and a slot. The slot can automatically close when a reverse air pressure, oil pressure and water pressure is exerted on the upper part of the one-way valve, thus ensuring the reverse airflow is unpassable through the one-way valve.

It will be obvious to those skilled in the art that changes and modifications may be made, and therefore, the aim in the appended claims is to cover all such changes and modifications.
