Patent Description:
At present, electronic cigarettes have become a relatively mature smoking substitute in the market. The battery supplies power to the heating unit of the cartridge, so that the heating unit is electrically driven to heat the e-liquid to generate smoke for users to inhale.

In the traditional liquid-fillable atomizer, the liquid inlet hole of the atomizing shell is usually in communication with the liquid storage chamber. When the electronic cigarette is not used for a long time, the e-liquid in the liquid storage chamber may enter the atomizing shell via the liquid inlet hole, the liquid absorbing member in the atomizing shell may gradually absorb the e-liquid entering into the atomizing shell. The inner cavity of the atomizing shell is usually in communication with the outside world, and the e-liquid absorbed by the liquid absorbing member volatilizes to the outside world, and long-term contact with the air may cause the e-liquid to deteriorate. Additionally, the liquid absorbing member may repeatedly absorb the e-liquid entering into the atomizing shell, when the user uses the electronic cigarette again, part of the e-liquid in the liquid storage chamber has been absorbed by the liquid absorbing member, and the amount of e-liquid in the liquid storage chamber is reduced. As a result, it is difficult to store the e-cigarette in the liquid storage chamber, and even causes a waste of money.

Document <CIT> discloses an atomizer which includes an unlocking member, a movable sleeve and a fixed sleeve. The unlocking member is connected with the movable sleeve, and the movable sleeve is movably accommodated in the fixed sleeve. During the connection between the unlocking member and the upper cover, the lower end of the unlocking member abuts against the movable sleeve, so that the movable sleeve moves downward under the pushing of the unlocking member until the second liquid inlet is in communication with the first liquid inlet, and at this time, the liquid storage cavity is opened, and the e-liquid enters the atomizing cavity. When the unlocking member is separated from the upper cover, the resisting effect of the unlocking member on the movable sleeve disappears, and the movable sleeve is reset and moved upward under the elastic force of the first elastic member until the top end of the movable sleeve is resisted by the fixed sleeve to stop moving, and at this time, the second liquid inlet is staggered from the first liquid inlet, and the liquid storage cavity is closed, and the e-liquid cannot enter the atomizing cavity.

In view of the above, the present disclosure provides a cartridge and an electronic cigarette having the cartridge to solve the above-mentioned problems.

The present disclosure provides a cartridge and an electronic cigarette having the cartridge, which are set out in the appended set of claims.

In the cartridge of the present disclosure, since the movable structure includes an isolation guiding tube received in the cartridge shell and a movable tube at least partially disposed in the isolation guiding tube, the movable tube includes an operating portion and a shielding portion, the operating portion is received in the isolation guiding tube and one end of the operating portion extends out from the vent hole, the atomizing structure is provided with a liquid inlet hole capable of being communicated with the liquid storage chamber, the shielding portion is movably sleeved on the atomizing structure to shield or expose the liquid inlet hole, so that the liquid inlet hole is isolated from or in communication with the liquid storage chamber. When the user does not use the electronic cigarette, the shielding portion is sleeved on the atomizing shell to shield the liquid inlet hole. When the user uses the electronic cigarette, the shielding portion and the operating portion are separated, and the shielding portion moves relative to the atomizing shell to expose the liquid inlet hole, so that the liquid inlet hole is in communication with the liquid storage chamber. The electronic cigarette of the present disclosure can realize the isolation of the e-liquid from the cotton when the user does not use the electronic cigarette, thereby facilitating the storage of the e- liquid and preventing the e-liquid from deteriorating.

The terms used herein in the description of the present disclosure are only for the purpose of describing specific embodiments, and are not intended to limit the present disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

Please refer to <FIG>, the first embodiment of the present disclosure provides an electronic cigarette, the electronic cigarette includes a cartridge <NUM> and a battery device (not shown). The cartridge <NUM> is electrically connected to the battery device, and the cartridge <NUM> heats the e-liquid under the electric driving of the battery device, so that the e-liquid is atomized into smoke.

The cartridge <NUM> includes a cartridge main body <NUM> and a sealing structure <NUM> mounted at the lower end of the cartridge main body <NUM>. Please also refer to <FIG>, the cartridge main body <NUM> includes a cartridge shell <NUM>, and a movable structure <NUM> and an atomizing structure <NUM> received in the cartridge shell <NUM>. In the embodiment, the sealing structure <NUM> and the cartridge main body <NUM> are independent parts; alternatively, in another embodiment not shown, the sealing structure <NUM> can be integrally formed with the cartridge shell <NUM>.

In one embodiment, the cartridge shell <NUM> is substantially cylindrical with an opening at a bottom end thereof. The inner cavity of the cartridge shell <NUM> forms a liquid storage chamber <NUM>. The upper end of the cartridge shell <NUM> is provided with a vent hole <NUM> for one end of the movable structure <NUM> to extend through the upper end of the cartridge shell <NUM>, and a liquid injection hole <NUM> in communication with the liquid storage chamber <NUM>. The side wall of the cartridge shell <NUM> is provided with an air inlet hole <NUM>.

In another embodiment not shown, the cartridge shell <NUM> does not have the liquid injection hole <NUM>, but a pre-encapsulation method is used to inject the e-liquid into the cartridge <NUM> from the lower end of the cartridge shell <NUM>. After the e-liquid is consumed, the cartridge <NUM> is discarded as a whole, that is, the cartridge <NUM> cannot be refilled. The inner wall of the cartridge shell <NUM> adjacent to the vent hole <NUM> protrudes downwardly along the axial direction of the cartridge shell <NUM> to form a limiting portion <NUM> used for abutting against the movable structure <NUM>. An e-liquid plug <NUM> is provided in the liquid injection hole <NUM>. In this embodiment, the e-liquid plug <NUM> is made of rubber material. It can be understood that, in other embodiments not shown, the e-liquid plug <NUM> may also be made of other materials with good sealing property such as silicone. After the user fills the liquid storage chamber <NUM> with e-liquid through the liquid injection hole <NUM>, the e-liquid plug <NUM> is installed in the liquid injection hole <NUM>. The e-liquid plug <NUM> can seal the liquid injection hole <NUM> and prevent the e-liquid in the liquid storage chamber <NUM> from leaking via the liquid injection hole <NUM>.

Referring to <FIG>, an air inlet hole <NUM> is provided at one side of the lower end of the cartridge shell <NUM>, and external air can enter the cartridge <NUM> via the air inlet hole <NUM>. The number of the air inlet hole <NUM> can be N, wherein N is a natural number greater than or equal to one, and the distance between the air inlet holes <NUM> depends on the specific design. It can be understood that, in other embodiments not shown, the air inlet hole <NUM> may also be defined at the top, at one side of the upper end, or at the bottom of the cartridge shell <NUM>.

The movable structure <NUM> includes an isolation guiding tube <NUM> at least partially disposed in the limiting portion <NUM> and a movable tube <NUM> movably disposed in the isolation guiding tube <NUM>. The isolation guiding tube <NUM> has a structure with both ends being opened.

Referring to <FIG>, <FIG> and <FIG>, the isolation guiding tube <NUM> is made of stainless steel. It can be understood that, in other embodiments not shown, the isolation guiding tube <NUM> may also be made of titanium alloy or other materials with high hardness. The inner cavity of the isolation guiding tube <NUM> is in communication with the vent hole <NUM>. The isolation guiding tube <NUM> includes a connecting pipe <NUM> abutting against the inner surface of the limiting portion <NUM>, and a receiving portion <NUM> connected to a lower end of the connecting pipe <NUM>. The receiving portion <NUM> extends radially outwards from the connecting pipe <NUM> and then extends downwards. The connecting pipe <NUM> and the receiving portion <NUM> are each cylindrical. The receiving portion <NUM> divides the connecting pipe <NUM> into a connecting section <NUM> connected with the limiting portion <NUM> and a cutting portion <NUM> capable of resisting the movable tube <NUM>.

In this embodiment, the outer surface of the connecting section <NUM> and the inner surface of the limiting portion <NUM> are connected by an interference fit, and the upper end of the connecting section <NUM> abuts against the inner wall of the cartridge shell <NUM>. It can be understood that, in other embodiments not shown, the connecting section <NUM> may also be integrally formed with the limiting portion <NUM>. Or optionally, the limiting portion <NUM> may be omitted, and when the limiting portion <NUM> is omitted, the connecting section <NUM> and the cartridge shell <NUM> are integrally formed, as long as the inner cavity of the connecting section <NUM> is in communication with the vent hole <NUM>.

Please refer to <FIG> again, the movable tube <NUM> is made of silicone material. It can be understood that, in other embodiments not shown, the movable tube <NUM> may also be made of soft materials such as rubber or plastic. The movable tube <NUM> includes an operating portion <NUM> located in the connecting pipe <NUM> and extending out of the cartridge shell <NUM> from the vent hole <NUM>, and a shielding portion <NUM> connected to the lower end of the operating portion <NUM> corresponding to the inner cavity of the receiving portion <NUM>. The axial length of the operating portion <NUM> is greater than the axial length of the connecting pipe <NUM>. The upper end of the shielding portion <NUM> is provided with a cutting groove <NUM> corresponding to the cutting portion <NUM> around the periphery of the operating portion <NUM>. The outer surface of the shielding portion <NUM> is protruded to form an abutting portion <NUM> along the circumferential direction of the shielding portion <NUM>. The user can upwardly pull the upper end of the operating portion <NUM> that is extended to the outside of the vent hole <NUM> to drive the shielding portion <NUM> to move upwards. When the inner bottom wall of the cutting groove <NUM> gradually resists the cutting portion <NUM>, the abutting portion <NUM> gradually resists the inner surface of the receiving portion <NUM>. Since the upper end of the shielding portion <NUM> is provided with a cutting groove <NUM> corresponding to the cutting portion <NUM> around the periphery of the operating portion <NUM>, the connection between the shielding portion <NUM> and the operating portion <NUM> is relatively fragile. When the inner bottom wall of the cutting groove <NUM> completely resists the cutting portion <NUM>, the user can continue to pull the operating portion <NUM> upwards so that the operating portion <NUM> is separated from the shielding portion <NUM>; at this time, the abutting portion <NUM> resists the inner surface of the receiving portion <NUM>, so that the shielding portion <NUM> can be fixed relative to the receiving portion <NUM> under the action of the resisting force. In this embodiment, the cutting groove <NUM> is designed to be annular for convenient processing.

It can be understood that, in other embodiments not shown, only the shielding portion <NUM> is made of a soft material such as silicone. The soft material has good wrapping properties, and can better wrap the atomizing shell <NUM>, so as to better shield the liquid inlet hole <NUM>. The operating portion <NUM> and the shielding portion <NUM> are detachably connected, for example, the operating portion <NUM> is connected to the upper end of the shielding portion <NUM> by threads. Correspondingly, when it needs to expose the liquid inlet hole <NUM>, the operating portion <NUM> is pulled upwards firstly. The cutting groove <NUM> is non-continuous, for example, it has one, two or three arc-shaped groove segments, and the cutting portion <NUM> matching with the non-continuous cutting groove <NUM> is also set to be non-continuous, it only needs to ensure that when the shielding portion <NUM> moves upward under the driving of the operating portion <NUM> and resists the upper end of the receiving portion <NUM>, the cutting portion <NUM> can insert into the cutting groove <NUM>. Since both of the cutting portion <NUM> and the cutting groove <NUM> are non-continuous, and the connecting pipe <NUM> cannot be rotated or requires a greater force to rotate, the operating portion <NUM> can be separated from the shielding portion <NUM> by continuing to rotate the operating portion <NUM>. The operating portion <NUM> can be recycled and reused, reducing pollution and reducing costs.

It can be understood that, in other embodiments not shown, the shielding portion <NUM> and the operating portion <NUM> can be detachably connected. The detachable connection includes but not limited to a snapping connection, a plugging connection, etc..

It can be understood that, in other embodiments not shown, a groove (not shown) is provided on the inner wall of the receiving portion <NUM>. When the user pulls the operating portion <NUM> upward to drive the shielding portion <NUM> to move upward, the abutting portion <NUM> can engage in the groove, so that the shielding portion <NUM> is more firmly fixed in the receiving portion <NUM>. Or optionally, the abutting portion <NUM> can be omitted. When the abutting portion <NUM> is omitted, the inner wall of the receiving portion <NUM> is provided with a protrusion, when the user pulls the operating portion <NUM> upwards to drive the shielding portion <NUM> to move upward, the protrusion can resist against the outer surface of the shielding portion <NUM>, so that the shielding portion <NUM> can be fixed relative to the receiving portion <NUM> under the action of the resisting force. Or optionally, the shielding portion <NUM> is further provided with a latching slot (not shown), when the user pulls the operating portion <NUM> upwards to drive the shielding portion <NUM> to move upwards, the protrusion can engage in the latching slot, so that the shielding portion <NUM> is more firmly fixed in the receiving portion <NUM>.

The atomizing structure <NUM> includes an atomizing shell <NUM> received in the shielding portion <NUM>, and a heating member <NUM> and a liquid absorbing member <NUM> installed in the atomizing shell <NUM>. The liquid absorbing member <NUM> engages with the heating member <NUM>. For example, the liquid absorbing member <NUM> is wrapped around the heating member <NUM>, and the liquid absorbing member <NUM> is interposed between the atomizing shell <NUM> and the heating member <NUM>.

The atomizing shell <NUM> is open at both ends, and the side wall of the atomizing shell <NUM> is provided with a liquid inlet hole <NUM>. After the shielding portion <NUM> moves upward, the liquid inlet hole <NUM> is in communication with the liquid storage chamber <NUM>. Specifically, pulling the operating portion <NUM> upwards by the user can irreversibly switch the shielding portion <NUM> from a first state to a second state; in the first state, the shielding portion <NUM> is sleeved on the atomizing shell <NUM> to shield the liquid inlet hole <NUM> of the atomizing shell <NUM>, and the liquid inlet hole <NUM> is isolated from the liquid storage chamber <NUM>; in the second state, the shielding portion <NUM> and the operating portion <NUM> are separated, the shielding portion <NUM> moves relative to the atomizing housing <NUM> to expose the liquid inlet hole <NUM>, and the liquid inlet hole <NUM> is in communication with the liquid storage chamber <NUM>. It can be understood that, in this embodiment, "irreversibly" means that, after the shielding portion <NUM> is switched from the first state to the second state, the shielding portion <NUM> can no longer be switched from the second state to the first state.

The atomizing shell <NUM> further provides an atomizing chamber (not labeled) therein, and the atomizing chamber is in communication with the vent hole <NUM>. For example, in this embodiment, the heating member <NUM> is a cylindrical spiral heating wire, the inner cavity of the cylindrical spiral heating wire forms the atomizing chamber, and the smoke formed by heating the e-liquid by the heating member <NUM> is mainly formed in the atomizing chamber.

The liquid absorbing member <NUM> is made of cotton, cotton cloth, porous ceramics, or other materials that can easily absorb liquid. The liquid absorbing member <NUM> can gradually absorb the e-liquid, and gradually transfer the absorbed e-liquid to the heating member <NUM>, so that the heating member <NUM> heats and atomizes the e-liquid absorbed by the liquid absorbing member <NUM>.

Referring to <FIG> and <FIG>, the sealing structure <NUM> includes a cartridge plug <NUM> received in the cartridge shell <NUM> and sleeved on the atomizing shell <NUM>, a tail cap <NUM> connected to the cartridge plug <NUM>, an airway plug <NUM> disposed in the tail cap <NUM>, and electrode contact members <NUM> mounted to the tail cap <NUM> for connecting to the battery device.

The cartridge plug <NUM> is made of silicone material. It can be understood that, in other embodiments not shown, the cartridge plug <NUM> also may be made of a material with good sealing properties such as rubber. A receiving hole <NUM> corresponding to the atomizing shell <NUM> is defined in the cartridge plug <NUM>. The cartridge plug <NUM> constitutes the bottom wall of the liquid storage chamber <NUM>.

Please refer to <FIG> again, the tail cap <NUM> includes a base <NUM> provided at the lower end of the cartridge shell <NUM> and a cap body <NUM> provided on the base <NUM> and connected to the cartridge plug <NUM>. The base <NUM> is provided with a plurality of cutouts <NUM> in communication with the air inlet hole <NUM>, the cap body <NUM> is located in the cartridge plug <NUM>, and the cap body <NUM> is provided with a plurality of guiding holes (not shown) in communication with the cutouts <NUM>.

The airway plug <NUM> is received in the cap body <NUM>. The airway plug <NUM> is provided with a plurality of airway holes <NUM> in communication with the atomizing chamber and the guiding holes. The external air can enter the atomizing chamber through the air inlet hole <NUM>, the cutouts <NUM>, the guiding holes and the airway holes <NUM> in sequence, so that the external air can be mixed with the smoke in the atomizing chamber.

In this embodiment, there are two electrode contact members <NUM>, and the two electrode contact members <NUM> are installed to the base <NUM> at intervals. When the two electrode contact members <NUM> are respectively connected to the positive electrode and the negative electrode of the battery device, the electronic cigarette is activated and the circuit is turned on.

Installation process: the atomizing shell <NUM> is mounted in the shielding portion <NUM>, the cartridge plug <NUM> is sleeved at the lower end of the atomizing shell <NUM>, so that the liquid inlet hole <NUM> is shielded by the shielding portion <NUM>; the liquid absorbing member <NUM> and the heating member <NUM> are mounted in the atomizing shell <NUM>, the airway plug <NUM> is mounted in the cap body <NUM>, the cap body <NUM> is received in the cartridge plug <NUM>, and the base <NUM> is mounted at the lower end of the cartridge shell <NUM>; finally, the operating portion <NUM> is inserted into the connecting pipe <NUM> and extends to the outside from the vent hole <NUM>; at this time, the air inlet hole <NUM>, the cutouts <NUM>, the guiding holes, the airway holes <NUM> and the atomizing chamber are in communication with each other; the battery device is installed on the cartridge <NUM>, so that the two electrode contact members <NUM> are respectively connected to the positive and negative electrodes of the battery device.

In use: when injecting liquid, the user can inject liquid into the liquid storage chamber <NUM> through the liquid injection hole <NUM>. After the user finishes filling, the e-liquid plug <NUM> is mounted in the liquid injection hole <NUM>, the e-liquid plug <NUM> can seal the liquid injection hole <NUM> and prevent the e-liquid in the liquid storage chamber <NUM> from leaking.

When the user does not use the cartridge <NUM>, the liquid inlet hole <NUM> is shielded by the shielding portion <NUM>, and the liquid inlet hole <NUM> is isolated from the liquid storage chamber <NUM>. When the user uses the cartridge <NUM>, the user can upwardly pull the upper end of the operating portion <NUM> that is extended to the outside of the vent hole <NUM> to drive the shielding portion <NUM> to move upward. When the inner bottom wall of the cutting groove <NUM> gradually resists the cutting portion <NUM>, the abutting portion <NUM> gradually resists the inner surface of the receiving portion <NUM>. Since the upper end of the shielding portion <NUM> is provided with a cutting groove <NUM> corresponding to the cutting portion <NUM> around the periphery of the operating portion <NUM>, the connection between the shielding portion <NUM> and the operating portion <NUM> is relatively fragile. When the inner bottom wall of the cutting groove <NUM> completely resists the cutting portion <NUM>, the user can continue to pull the operating portion <NUM> upward so that the operating portion <NUM> can be separated from the shielding portion <NUM>; at this time, the abutting portion <NUM> completely resists the inner surface of the receiving portion <NUM>, so that the shielding portion <NUM> can be fixed relative to the receiving portion <NUM> under the action of the resisting force, the shielding portion <NUM> no longer shields the liquid inlet hole <NUM> or shields part of the liquid inlet hole <NUM>, the liquid inlet hole <NUM> is in communication with the liquid storage chamber <NUM>, the e-liquid in the liquid storage chamber <NUM> can enter the atomizing shell <NUM> through the liquid inlet hole <NUM>, the e-liquid is gradually absorbed by the liquid absorbing member <NUM> in the atomizing shell <NUM>, and the absorbed e-liquid is gradually transferred to the heating member <NUM>.

When inhaling, the electronic cigarette is powered on, the positive and negative electrodes of the battery device are respectively connected to the two electrode contact members <NUM>, the circuit of the electronic cigarette is turned on, the heating member <NUM> starts to heat and atomize the e-liquid absorbed by the liquid absorbing member <NUM>; the external air can enter the atomizing chamber through the air inlet hole <NUM>, the cutouts <NUM>, the guide holes and the airway holes <NUM> in sequence, so that the external air is mixed with the smoke in the atomizing chamber, and the user can inhale the smoke via the vent hole <NUM>.

Please refer to <FIG> at the same time, the main difference between the cartridge <NUM> provided in the second embodiment and the cartridge <NUM> in the first embodiment is as follows. The cartridge plug <NUM> and the lower end of the shielding portion <NUM> are integrally formed. An annular cut <NUM> is formed along the circumference of the shielding portion <NUM> at the junction of the cartridge plug <NUM> and the shielding portion <NUM>. When the user upwardly pulls the upper end of the operating portion <NUM> that is extended to the outside of the vent hole <NUM>, the operating portion <NUM> drives the shielding portion <NUM> to move upward. After the operating portion <NUM> drives the shielding portion <NUM> to move upward for a certain distance, since the junction between the cartridge plug <NUM> and the shielding portion <NUM> is provided with an annular cut <NUM>, the connection between the cartridge plug <NUM> and the shielding portion <NUM> is relatively fragile, the cartridge plug <NUM> is gradually separated from the shielding portion <NUM>. When the inner bottom wall of the cutting groove <NUM> gradually resists the lower end of the connecting pipe <NUM>, the abutting portion <NUM> gradually resists the outer surface of the connecting pipe <NUM>. Since the upper end of the shielding portion <NUM> is provided with a cutting groove <NUM> corresponding to the cutting portion <NUM> around the periphery of the operating portion <NUM>, the connection between the shielding portion <NUM> and the operating portion <NUM> is relatively fragile. When the inner bottom wall of the cutting groove <NUM> completely resists the connecting pipe <NUM>, the user can continue to pull the operating portion <NUM> upwards to separate the operating portion <NUM> from the shielding portion <NUM>. At this time, the abutting portion <NUM> completely resists the outer surface of the connecting pipe <NUM>, and the shielding portion <NUM> can be fixed relative to the connecting pipe <NUM> under the action of the resisting force, the liquid inlet hole <NUM> is in communication with the liquid storage chamber <NUM>, the e-liquid in the liquid storage chamber <NUM> can enter the atomizing shell <NUM> through the liquid inlet hole <NUM>, the e-liquid is gradually absorbed by the liquid absorbing member <NUM> in the atomizing shell <NUM>, and the absorbed e-liquid is gradually transferred to the heating member <NUM>.

In this embodiment, the receiving portion <NUM> is omitted. When the user upwardly pulls the upper end of the operating portion <NUM> that is extended to the outside of the vent hole <NUM>, the operating portion <NUM> drives the shielding portion <NUM> to move upward, the inner bottom wall of the cutting groove <NUM> gradually resists the lower end of the cutting portion <NUM>, the abutting portion <NUM> gradually resists the outer surface of the cutting portion <NUM>. When the inner bottom wall of the cutting groove <NUM> completely resists the cutting portion <NUM>, the user can continue to pull the operating portion <NUM> upwards so that the operating portion <NUM> is separated from the shielding portion <NUM>. At this time, the abutting portion <NUM> completely resists the outer surface of the cutting portion <NUM>, the shielding portion <NUM> can be fixed relative to the connecting pipe <NUM> under the action of the resisting force.

It can be understood that, in other embodiments not shown, a sliding rail (not shown) is provided on the inner surface of the connecting section of the cartridge plug <NUM> and the shielding portion <NUM>, the outer wall of the atomizing shell <NUM> is provided with a sliding slot (not shown) corresponding to the sliding rail. When the cartridge <NUM> is not in use, the slide rail is located in the sliding slot. With the cooperation of the sliding rail and the sliding slot, the cartridge plug <NUM> and the shielding portion <NUM> remain relatively fixed. When the user upwardly pulls the upper end of the operating portion <NUM> that is extended to the outside of the vent hole <NUM>, the sliding rail gradually separates from the sliding slot, so that the cartridge plug <NUM> and the shielding portion <NUM> are gradually separated from each other. It can be understood that, in other embodiments not shown, it only requires that the user can upwardly pull the upper end of the operating portion <NUM> that is extended to the outside of the vent hole <NUM>, the operating portion <NUM> can drive the shielding portion <NUM> to move upward for a certain distance, and the cartridge plug <NUM> can be gradually separated from the shielding portion <NUM>.

In the electronic cigarette of the present disclosure, since the movable structure <NUM> includes an isolation guiding tube <NUM> received in the cartridge shell <NUM> and a movable tube <NUM> at least partially disposed in the isolation guiding tube <NUM>, the movable tube <NUM> includes an operating portion <NUM> and a shielding portion <NUM>, the operating portion <NUM> is received in the isolation guiding tube <NUM> and one end of the operating portion <NUM> extends out from the vent hole <NUM>, the atomizing structure <NUM> is provided with a liquid inlet hole <NUM> capable of being communicated with the liquid storage chamber <NUM>, the shielding portion <NUM> is movably sleeved on the atomizing structure <NUM> to shield or expose the liquid inlet hole <NUM>, so that the liquid inlet hole <NUM> is isolated from or in communication with the liquid storage chamber <NUM>. When the user does not use the electronic cigarette, the shielding portion <NUM> is sleeved on the atomizing shell <NUM> to shield the liquid inlet hole <NUM>. When the user uses the electronic cigarette, the shielding portion <NUM> and the operating portion <NUM> are separated, and the shielding portion <NUM> moves relative to the atomizing shell <NUM> to expose the liquid inlet hole <NUM>, so that the liquid inlet hole <NUM> is in communication with the liquid storage chamber <NUM>. The electronic cigarette of the present disclosure can realize the isolation of the e-liquid from the cotton when the user does not use the electronic cigarette, thereby facilitating the storage of the e-liquid.
