Abstract

An electronic cigarette (e-cigarette) capable of holding, heating, and quantitatively supplying a gelled electronic liquid (e-liquid) is provided. The e-cigarette includes an upper housing, a lower housing, a gel container, a press and reset mechanism, and an aerosol channel. The gelled e-liquid is supplied quantitatively to a heating chamber by manually pressing the press and reset mechanism. The user can adjust the time interval between pressing and releasing the press and reset mechanism according to the needs of the user for each inhalation by adjusting the length of the gelled e-liquid stick supplied to the heating chamber. Besides, a holder is provided therein with heating plates at different positions, and the holder also serves as a heating element. The design avoids the need to provide the heating element and the heating chamber separately, which reduces the volume of the smoking device.

First claim

What is claimed is:

1. An electronic cigarette (e-cigarette) capable of holding, heating, and
quantitatively supplying a gelled electronic liquid (e-liquid), comprising an upper housing, a lower housing, a gel container, a press and reset mechanism, and an aerosol channel, wherein
an inner wall of the upper housing has an upper end provided with a limit ring and a lower end provided with a stop ring;
the gel container is a hollow cylinder, and a lower end of the gel container is provided with a hollow holder; and a connecting position between the hollow holder and the gel container is a gradual extension structure;
a side wall of the hollow holder is longitudinally provided with a plurality of gaps, and the plurality of gaps divide the side wall of the hollow holder into a plurality of holding portions; the gradual extension structure of the hollow holder is in movable contact with the stop ring; and each of the plurality of holding portions is also a heating element;
the press and reset mechanism is connected to the gel container, and a part of the press and reset mechanism protrudes outside the upper housing;
the plurality of holding portions are provided with a plurality of longitudinally spaced heating plates; and
wherein the press and reset mechanism comprises a press sleeve, a mouthpiece, and a reset spring;
wherein the press sleeve is inserted into an upper end of the mouthpiece;
the mouthpiece is clamped into the upper housing and protrudes from the upper housing, and the mouthpiece is connected to the gel container and in communication with the aerosol channel; and
the reset spring is sleeved outside the gel container and has an upper end abutted against the mouthpiece and a lower end abutted against the limit ring.

2. The e-cigarette according to claim 1 , wherein the upper housing comprises an upper section and a lower section, and the upper section is detachably connected to the lower section; the limit ring and the stop ring are arranged on an inner wall of the lower section; and the mouthpiece is detachably connected to the gel container.

3. The e-cigarette according to claim 1 , wherein the mouthpiece is T-shaped, and a T-shaped channel is provided in the mouthpiece; and the aerosol channel comprises a gap between the upper housing and the gel container; and
the side wall of the hollow holder is provided with a through hole.

4. A method of using the e-cigarette according to claim 1 , comprising: pressing the press and reset mechanism to drive the gel container to move downward, so the gradual extension structure is released from the stop ring and a part of a gelled e-liquid stick held by the gradual extension structure falls to a lower end of the hollow holder; releasing the press and reset mechanism, so the press and reset mechanism is reset to drive the gel container to move upward, wherein when the hollow holder moves upward and contacts with the stop ring, the hollow holder tightens to hold the gelled e-liquid stick; and starting a heating process of a smoking device, so the hollow holder heats the gelled e-liquid stick in the hollow holder, and an aerosol produced by the gelled e-liquid stick enters the aerosol channel for a user to inhale.

5. The method according to claim 4 , wherein in the e-cigarette, the upper housing comprises an upper section and a lower section, and the upper section is detachably connected to the lower section; the limit ring and the stop ring are arranged on an inner wall of the lower section; and the mouthpiece is detachably connected to the gel container.

6. The method according to claim 4 , wherein in the e-cigarette, the mouthpiece is T-shaped, and a T-shaped channel is provided in the mouthpiece; and the aerosol channel comprises a gap between the upper housing and the gel container; and
the side wall of the hollow holder is provided with a through hole.
