Description

an electronic cigarette

technical field

The present invention particularly relates to an electronic cigarette.

Background technique

At present, electronic cigarettes on the market that rely on heating solid tobacco products to obtain smoke include a casing, and a smoke storage pipe is arranged in the casing. When in use, the tobacco part of the cigarette is placed in the smoke storage pipe. Since the existing cigarette storage tubes are fixed in the casing of the electronic cigarette, when the inner cavity of the cigarette storage tube needs to be cleaned, it is necessary to disassemble the casing of the electronic cigarette with a screwdriver before cleaning the cigarette storage tube, which is inconvenient to operate and affects the User experience.

In addition, there is only one heating unit in the existing electronic cigarette casing, and the heating unit directly contacts and heats the tobacco part of the cigarette to generate smoke for the user to smoke. In order to heat the electronic cigarette evenly and atomically, the temperature provided by the heating unit is generally above 350°C, which is relatively high, resulting in a complex thermal insulation structure of the electronic cigarette, and at the same time, it is prone to local burning or scalding of the oral cavity. Furthermore, since the heating unit requires a certain heating time, at the beginning of smoking, the tobacco part cannot immediately atomize the smoke, the smoke output speed is slow, the smoke volume is unstable, and the user experience is poor.

SUMMARY OF THE INVENTION

In the existing electronic cigarette, the smoke storage pipe is fixed in the casing and only has a heating unit, which is inconvenient to clean the smoke storage pipe; the heating unit has a high temperature, which makes the heat insulation structure of the electronic cigarette complex, and is prone to local occurrences. Burning or scalding of the oral cavity; the tobacco department cannot immediately atomize the smoke, the smoke output is slow, the smoke volume is unstable, and the user experience is poor. The purpose of the present invention is to provide an improved electronic cigarette in view of the above-mentioned deficiencies of the prior art, which is convenient for cleaning the cigarette storage pipe, can fully and uniformly heat and atomize the tobacco part of the cigarette, and at the same time, the temperature is low, and the heat insulation is reduced. The structure is simple, the phenomenon of partial burning of the tobacco part or the oral cavity will not occur, the smoke output speed is fast, the smoke volume and the smoke temperature are stable, the long-term use is not hot to the hand, and the user experience is good.

For solving the above-mentioned technical problems, the technical scheme adopted in the present invention is:

An electronic cigarette includes a casing and a smoke storage tube in the casing, and its structural feature is that it also includes an ejection mechanism that can push the smoke storage tube out of the outer casing, and is used to control whether the ejection mechanism ejects the smoke storage tube or not. The unlocking unit of the pipe is connected with the smoke storage pipe through an ejector mechanism.

With the above structure, when the inner cavity of the smoke storage pipe needs to be cleaned, the ejection mechanism can be unlocked directly through the unlocking unit, and the ejection mechanism can push the smoke storage pipe out of the casing, so that it is convenient for the user to pull out the smoke storage pipe and remove it. Clean, easy to operate, good user experience.

As a preferred way, the ejection mechanism includes an ejection fixed seat, an ejection spring and an ejection sleeve in the casing, the smoke storage pipe passes through the ejection fixed seat and does not contact the ejection fixed seat, and the ejection sleeve is sleeved Outside the ejecting fixing seat, one end of the ejecting spring is in contact with the ejecting fixing seat, and the other end of the ejecting spring is abutting with the ejecting sleeve; the unlocking unit can drive the smoke storage pipe to move out of the casing by controlling the ejecting sleeve; When the unlocking unit locks the ejecting sleeve, the ejecting spring is in a compressed state; when the unlocking unit unlocks the ejecting sleeve, the ejecting sleeve moves out of the casing under the action of the restoring force of the ejecting spring and ejects the smoke storage tube.

With the above structure, when the unlocking unit unlocks the ejection sleeve, both the smoke storage pipe and the ejection sleeve are pushed up by the ejection spring, which is convenient for the user to pull out the smoke storage pipe for cleaning.

Further, the ejection mechanism also includes an ejection base in the outer shell, the ejection sleeve is arranged in the ejection base and is in interference fit with the ejection base, and the bottom of the ejection sleeve is provided with a base to prevent the ejection sleeve from being detached from the ejection and fixed. seat limit.
