Abstract

The invention discloses an atomizing device of electronic cigarette and an electronic cigarette having same. The atomizing device comprises a main body, a heating device and a waterproof and breathable membrane, wherein the main body is provided with an air inlet, a suction port and an oil storage chamber, the main body forms an airflow channel between the air inlet and the suction port, the heating device is partially received in the airflow channel and is communicated with the oil storage chamber, the waterproof and breathable membrane is installed on the main body, and the waterproof and breathable membrane covers the airflow channel between the air inlet and the heating device. The technical scheme of the invention effectively prevents the phenomenon that tobacco liquid and condensed water leak out of the air inlet so as to cause damage to external components.

First claim

What is claimed is:

1. An atomizing device of an electronic cigarette, comprising a main body, a heating device and a waterproof and breathable membrane, wherein the main body is provided with an air inlet, a suction port and an oil storage chamber, the main body forms an airflow channel between the air inlet and the suction port, the heating device is partially received in the airflow channel and is communicated with the oil storage chamber, the waterproof and breathable membrane is installed on the main body, and the waterproof and breathable membrane covers the airflow channel between the air inlet and the heating device;
wherein the waterproof and breathable membrane comprises a base material with waterproof and breathable properties and an anti-wrinkle ring, the anti-wrinkle ring covers a edge of the base material so that when the base material is installed on the main body, a part of the base material not covered by the anti-wrinkle ring covers the airflow channel and forms a breathable cart, and the breathable cart is communicated with the airflow channel through an air path;
wherein the main body comprises a base body and a chassis: the air inlet is provided on the chassis, the airflow channel forms an air passage hole communicated with the air inlet on an outer surface of the chassis, the chassis is further provided with an installing groove on a periphery of the air passage hole, the waterproof breathable membrane is installed in the installing groove, and the breathable part of the waterproof breathable membrane covers the air passage hole so that the breathable part is communicated with the air passage hole through the air path; and the suction port, the oil storage chamber and the heating device are received in the base body, when the base body is installed on the chassis, the base body covers the installing groove, and the heating device is communicated with the breathable part of the waterproof and breathable membrane; and
wherein a thickness of the waterproof and breathable membrane is larger than or equal to a depth of the installing groove and when being installed on the chassis, the base body abuts against the anti-wrinkle ring to press the waterproof and breathable membrane into the installing groove.

2. The atomizing device of the electronic cigarette according to claim 1 , wherein the thickness of the waterproof and breathable membrane is equal to the depth of the installing groove, and the waterproof and breathable membrane further comprises an adhesive layer, the adhesive layer is provided on a surface of the base material facing away from the anti-wrinkle ring, so that the base material is adhered to an inner groove wall of the installing groove.

3. An electronic cigarette, wherein the electronic cigarette comprises the atomizing device of the electronic cigarette, wherein the atomizing device comprises a main body, a heating device and a waterproof and breathable membrane, wherein the main body is provided with an air inlet, a suction port and an oil storage chamber, the main body forms an airflow channel between the air inlet and the suction port, the heating device is partially received in the airflow channel and is communicated with the oil storage chamber, the waterproof and breathable membrane is installed on the main body, and the waterproof and breathable membrane covers the airflow channel between the air inlet and the heating device;
wherein the waterproof and breathable membrane comprises a base material with waterproof and breathable properties and an anti-wrinkle ring, the anti-wrinkle ring covers a edge of the base material so that when the base material is installed on the main body, a part of the base material not covered by the anti-wrinkle ring covers the airflow channel and forms a breathable part, and the breathable part is communicated with the airflow channel through the air path;
wherein the main body comprises a base body and a chassis: the air inlet is provided on the chassis, the airflow channel forms an air passage hole communicated with the air inlet on an outer surface of the chassis, the chassis is further provided with an installing groove on a periphery of the air passage hole, the waterproof breathable membrane is installed in the installing groove, and the breathable part of the waterproof breathable membrane covers the air passage hole so that the breathable part is communicated with the air passage hole through the air path; and the suction port, the oil storage chamber and the heating device are received in the base body, when the base body is installed on the chassis, the base body covers the installing groove, and the heating device is communicated with the breathable part of the waterproof and breathable membrane; and
wherein a thickness of the waterproof and breathable membrane is larger than or equal to a depth of the installing groove, and when being installed on the chassis, the base body abuts against the anti-wrinkle ring to press the waterproof and breathable membrane into the installing groove.

4. The electronic cigarette according to claim 3 , wherein the thickness of the waterproof and breathable membrane is equal to the depth of the installing groove, and the waterproof and breathable membrane further comprises an adhesive layer, the adhesive layer is provided on a surface of the base material facing away from the anti-wrinkle ring, so that the base material is adhered to an inner groove wall of the installing groove.

5. The electronic cigarette according to claim 3 , wherein the difference between the thickness of the waterproof and breathable membrane and the depth of the installing groove is in a range from 1 mm to 2 mm, so that a maximum distance, in which the waterproof and breathable membrane is separated from the inner groove wall of the installing groove under an urging force of the airflow drawn through the air inlet, has a value of 1 mm to 2 mm; and/or a thickness of the base material has a value of 0.1 mm to 0.5 mm.

6. The electronic cigarette according to claim 3 , wherein the chassis is further provided with at least one stopper, one end of the at least one stopper is fixed to the chassis and the other end thereof is placed in a notch of the installing groove, and the waterproof and breathable membrane abuts against the at least one stopper when moving outside the installing groove under the urging force of the airflow.

7. The electronic cigarette according to claim 3 , wherein one of the waterproof and breathable membrane and the chassis is provided with a positioning member and the other of the waterproof and breathable membrane and the chassis is correspondingly provided with a positioning groove, and when the waterproof and breathable membrane is installed in the installing groove, the positioning member is inserted into the positioning groove.
