As shown in fig. 1 to 12, an electronic cigarette 100 according to an embodiment of the present invention includes a housing 110, an atomizer 130, a limiting component, and a second reset element 190.

Wherein, in particular, the housing 110 has an interior cavity 111, the interior cavity 111 having an open first end 113. The atomizer 130 is inserted into the cavity 111 of the housing 110. The atomizer 130 is movable in a first direction a-a to switch between a first position and a second position. Atomizer 130 has an outlet end 131. When the atomizer 130 is in the first position, the air outlet end 131 of the atomizer 130 is exposed from the first end 113 of the interior cavity 111, as shown in fig. 2-4. When the atomizer 130 is in the second position, the air outlet end 131 of the atomizer 130 is positioned in the interior cavity 111 of the housing 110, as shown in fig. 7-9.

The limiting assembly includes a limiting member 151 rotatably disposed in the cavity 111 of the housing 110 and a first reset member 153. The stopper 151 is rotatable to switch among a first state, a second state, and a third state. When the atomizer 130 moves from the first position to the second position, the limiting member 151 can be driven to rotate from the first state to the second state along the first rotation direction. When the atomizer 130 is located at the second position and the limiting member 151 is in the second state, the first reset member 153 can drive the limiting member 151 to rotate to the third state along the second rotation direction opposite to the first rotation direction, so as to limit the atomizer 130 to move along the first direction a-a. Specifically, as shown in fig. 2 and 4, the stopper 151 is in the first state; as shown in fig. 5 and 6, the stopper 151 is in the second state; as shown in fig. 7 and 8, the stopper 151 is in the third state.

The second restoring member 190 is disposed in the cavity 111 of the housing 110. When the atomizer 130 is located at the second position and the limiting member 151 is located at the second state, the second reset member 190 can drive the atomizer 130 to move from the second position to the first position.

In the electronic cigarette 100, when the atomizer 130 is located at the first position, the air outlet end 131 of the atomizer 130 is partially exposed from the first end 113 of the inner cavity 111, so as to be convenient for the user to inhale. When the atomizer 130 is located at the second position and the limiting member 151 is in the second state, the first reset member 153 can drive the limiting member 151 to rotate to the third state so as to limit the atomizer 130 to move along the first direction a-a, namely, the atomizer 130 is kept at the second position, so that the air outlet end 131 of the atomizer 130 is kept at the inner cavity 111 of the shell 110, long-term exposure of the air outlet end 131 of the atomizer 130 can be avoided, the risk that the air outlet end 131 of the atomizer 130 is polluted due to long-term exposure is avoided, and sucking sanitation is ensured; the air outlet end 131 of the atomizer 130 is prevented from being collided by external force due to long-term exposure, so that the risk of easy damage to the air outlet end 131 of the atomizer 130 is reduced, and the service life of the atomizer 130 is prolonged.

Of course, it will be appreciated that when the atomizer 130 is required to move from the second position to the first position, the unlocking member 170 drives the limiting member 151 to rotate to the second state, so that the atomizer 130 can move to the first position under the action of the second resetting member 190.

In addition, in the present embodiment, when the atomizer 130 is located at the first position, the air outlet end 131 of the atomizer 130 is located in the inner cavity 111 of the housing 110, so as to reduce the volume of the electronic cigarette 100, meet the miniaturization requirement of the electronic cigarette 100, and facilitate storage and carrying of the electronic cigarette 100. In addition, when the atomizer 130 is located at the second position, the air outlet end 131 of the atomizer 130 is located in the inner cavity 111 of the housing 110, so that the air outlet end 131 of the atomizer 130 can be prevented from being polluted by external environment, and the air outlet end 131 of the atomizer 130 can be prevented from being damaged due to collision of external force, thereby reducing the placement condition of the atomizer assembly and being convenient for storage and carrying of the atomizer assembly.

It will be appreciated that the user draws in the smoke generated by the atomizer 130 through the outlet end 131 of the atomizer 130. Therefore, in order to facilitate the sucking, the air outlet end 131 of the atomizer 130 is provided with a sucking portion. When the atomizer 130 is located at the first position, the sucking part of the atomizer 130 may be completely exposed from the first end 113 of the inner cavity 111, or may be partially exposed from the first end 113 of the inner cavity 111, so as to meet the sucking requirement of the user.

In this embodiment, referring to fig. 3, the first direction a-a is the extending direction of the atomizer 130, and is also the extending direction of the inner cavity 111 of the housing 110. Of course, it will be appreciated that in other possible embodiments, the first direction is not limited thereto, and may be biased to enable the mouthpiece to be switched between the first and second positions.

Referring to fig. 3 and 9, in the present embodiment, the electronic cigarette 100 further includes a base 120 disposed in the inner cavity 111 of the housing 110. The base 120 is disposed at one end of the atomizer 130 far away from the air outlet end 131, and is fixedly connected with the atomizer 130. When the atomizer 130 is located at the second position and the limiting member 151 is located in the third state, the limiting member 151 limits the movement of the base 120 along the first direction a-a, so as to limit the movement of the atomizer 130 along the first direction a-a.

Referring to fig. 2 to 11, in particular, in this embodiment, a limiting protrusion 121 is provided on the base 120. The stopper 151 has a first abutment surface 1511. The first abutment surface 1511 is provided with a limit groove 1513 matching with the limit projection 121. In the process of moving the atomizer 130 from the first position to the second position, the limiting protrusion 121 abuts against the first abutting surface 1511, so as to drive the limiting member 151 to rotate from the first state to the second state. When the limiting member 151 rotates to the third state under the action of the first reset member 153, the limiting protrusion 121 is trapped in the limiting groove 1513, so as to limit the movement of the limiting protrusion 121 along the first direction a-a, and further limit the movement of the base 120 along the first direction a-a. It can be appreciated that when the limiting protrusion 121 moves along the first direction a-a, the limiting protrusion 121 can abut against the first abutting surface 1511 to drive the limiting member 151 to rotate, so that the first abutting surface 1511 is not parallel to the first direction a-a when the limiting member 151 is in the first state; in addition, the first abutment surface 1511 is not parallel to the first direction a-a during the rotation of the stopper 151 from the first state to the second state.

In addition, in the present embodiment, when the atomizer 130 is located at the first position, the limiting protrusion 121 is not in contact with the first abutment surface 1511. After the atomizer 130 moves a certain distance from the first position to the second position, the limiting projection 121 abuts against the first abutment surface 1511. Of course, in another possible embodiment, the limiting projection may also abut the first abutment surface when the atomizer is in the first position.

It can be appreciated that in this embodiment, when the atomizer 130 has not moved to the second position, the limiter 151 is driven to rotate to the second state.

Referring to fig. 3, in the present embodiment, a limiting portion 115 is further disposed on an inner side wall of the housing 110, and along the first direction a-a, the limiting portion 115 is located on a side of the limiting protrusion 121 near the opening of the inner cavity 111. When the atomizer 130 is located at the first position, the limiting protrusion 121 abuts against the limiting portion 115. Thus, movement of the atomizer 130 to the first position is prevented from continuing until more is exposed from the first end 113 of the interior cavity 111. In addition, the atomizer 130 can be more stably located at the first position by the combined action of the limiting portion 115 and the second reset member 190.

Referring to fig. 2 and 4 to 8, in the present embodiment, the first restoring member 153 is an elastic member with one end connected to the housing 110 and the other end connected to the limiting member 151. More specifically, in the present embodiment, when the stopper 151 rotates from the first state to the second state, the first reset member 153 is compressed. Therefore, after the force for driving the limiting member 151 to rotate in the first rotation direction is removed, the first reset member 153 recovers the elastic deformation, so as to drive the limiting member 151 to rotate in the second rotation direction. It will be appreciated, of course, that in other possible embodiments, the first restoring member may be elongated by changing the connection locations of the first restoring member to the housing and the limiting member, respectively, such that the limiting member rotates from the first state to the second state. Similarly, after the force driving the limiting member to rotate along the first rotation direction disappears, the first reset member recovers the elastic deformation so as to drive the limiting member to rotate along the second rotation direction.

Referring to fig. 3 and 9, in the present embodiment, the second restoring member 190 is an elastic member with one end connected to the inner wall of the housing 110 and the other end connected to the base 120. More specifically, in the present embodiment, during the movement of the atomizer 130 from the first position to the second position, the atomizer 130 compresses the second restoring member 190 through the base 120. Therefore, when the base 120 is not limited by the limiting member 151, the second reset member 190 recovers the elastic deformation, so as to drive the base 120 to move along the first direction a-a, and further drive the atomizer 130 to move along the first direction a-a, i.e. reset the atomizer 130 to the first position. It will of course be appreciated that in other possible embodiments, the second return member may be elongated by changing the connection position of the second return member to the housing and base, respectively, such that the atomizer moves from the first position to the second position. Similarly, when the base is not limited by the limiting part, the second resetting part recovers elastic deformation so as to drive the base to move along the first direction and drive the atomizer to move along the first direction, namely resetting the atomizer to the first position.

In this embodiment, the base 120 magnetically attracts the bottom end of the atomizer 130. Therefore, the base 120 and the atomizer 130 are fixedly connected, and the atomizer 130 can be separated from the base 120 by overcoming the magnetic force of the atomizer 130 and the base 120 under the action of external force, namely, the atomizer 130 and the base 120 can be detached, so that the atomizer 130 is convenient to maintain and replace.

In this embodiment, the electronic cigarette 100 further includes an unlocking member 170, and the unlocking member 170 can drive the limiting member 151 to rotate along the first rotation direction to rotate from the third state to the second state, so that the atomizer 130 can move to the first position under the action of the second resetting member 190.

In this embodiment, the electronic cigarette 100 further includes a storage box 10, and the unlocking member 170 is fixedly disposed on the storage box 10. The housing 110 is provided with an unlocking perforation 117. The unlocking member 170 is inserted into the unlocking through hole 117 to drive the limiting member 151 to rotate from the third state to the second state. The unlocking member 170 is fixedly arranged on the storage box 10, so that the unlocking member 170 is convenient to store, and the unlocking member 170 is prevented from being discarded when not in use.

In this embodiment, the limiting member 151 has a second contact surface 1515, and the unlocking member 170 can be inserted into the unlocking through hole 117 to contact with the second contact surface 1515 of the limiting member 151, and can be continuously inserted into the unlocking through hole 117 to drive the limiting member 151 to rotate from the third state to the second state. In other words, the insertion depth of the unlocking piece 170 into the unlocking through hole 117 to drive the stopper 151 to rotate from the third state to the second state is set to be the unlocking depth. The unlocking piece 170 is inserted into the unlocking through hole 117 to an insertion depth abutting against the second abutting surface 1515, which is smaller than the unlocking depth. Therefore, the unlocking piece 170 can be inserted along the unlocking perforation 117 to drive the limiting piece 151 to rotate to the second state, other actions such as rotation are not needed, and the operation is simple and convenient.

Further, in the present embodiment, the second abutment surface 1515 is not parallel to or perpendicular to the depth direction of the unlocking through hole 117. It will be appreciated that in other possible embodiments, the second abutment surface may also be perpendicular to the depth direction of the unlocking perforation, depending on the location of the unlocking perforation. In a word, make the unblock piece with second butt face butt to can last with second butt face butt when inserting deeply, with drive the locating part rotate to the second state can.

In addition, it will be appreciated that in other possible embodiments, the process of rotating the drive limiter from the third state to the second state is not limited thereto, and may be driven in other ways, such as by electromagnetic driving or by other linkages, etc.

In this embodiment, the storage box 10 is provided with a stopper 11. When the housing 110 is stored in the storage box 10, the unlocking member 170 is inserted into the unlocking hole 117 to drive the limiting member 151 to rotate to the second state, and the blocking member 11 is arranged at the opening of the inner cavity 111 of the housing 110 to prevent the atomizer 130 from ejecting along the first direction a-a. In other words, after the housing 110 is accommodated in the accommodating case 10, the stopper 151 is adjusted to the second state. Therefore, when the housing 110 is detached from the storage box 10 in the next use, the atomizer 130 can be directly moved to the first position under the action of the second reset element 190, so that the operation of inserting the unlocking element 170 into the unlocking hole to drive the limiting element 151 to rotate to the second state is saved.

In this embodiment, the storage box 10 is provided with a first magnetic member 13, and the housing 110 is provided with a second magnetic member 119, so that the housing 110 is conveniently stored in the storage box 10. It will be appreciated that in other possible embodiments, the manner in which the housing 110 is secured to the case 10 is not limited thereto, and may be achieved by a snap fit or the like.

Optionally, after the housing 110 is received in the storage box 10, the blocking member 11 completely covers the opening of the inner cavity 111 of the housing 110, so that the atomizer 130 can be effectively prevented from being polluted by the external environment while the atomizer 130 is prevented from being separated, and the atomizer 130 is kept clean better.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The above examples illustrate only a few embodiments of the invention, which are described in detail and are not to be construed as limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention. Accordingly, the scope of protection of the present invention is to be determined by the appended claims.
