Referring to FIG. 1 , the first embodiment of the present invention provides an electronic cigarette (not shown), the electronic cigarette comprising an electronic cigarette charging device (not shown) and an electronic cigarette suction device 10 detachably mounted in the electronic cigarette charging device, the electronic cigarette suction device 10 being electrically connected to the electronic cigarette charging device. The electronic cigarette charging device can be used to charge the electronic cigarette suction device 10, and the electronic cigarette suction device 10 can atomize the tobacco product 20 placed therein.

The electronic cigarette suction device 10 comprises a sleeve 11 , a heating structure 12 mounted on one end of the sleeve 11 , and a movable member 13 detachably connected to one end of the sleeve 11 close to the heating structure 12 .

Please refer to Figures 2-6. The sleeve 11 is generally cylindrical in structure. The sleeve 11 includes a body 111 arranged along the axial direction and a mounting portion 112 arranged on one end of the body 111 near the heating structure 12. In this embodiment, the outer diameter of the mounting portion 112 is smaller than the outer diameter of the body 111. The mounting portion 112 includes a reserved section 1121 connected to the body 111 and a sliding section 1122 for connecting the movable member 13. In this embodiment, the end of the sleeve 11 facing the movable member 13 is the connecting end of the sleeve 11. The sliding section 1122 and the reserved section 1121 are integrally formed. An external thread section 1123 is arranged on the sliding section 1122 along the circumference of the sliding section 1122. At least one slide groove 1124 penetrating the external thread section 1123 is opened on the outer surface of the sliding section 1122 along the axial direction of the mounting portion 112. In this embodiment, there are four slide grooves 1124, and the four slide grooves 1124 are evenly distributed on the outer surface of the sliding section 1122 along the circumference of the sliding section 1122.

The heating structure 12 is at least partially protruded from the connection end of the sleeve 11. In this embodiment, the heating structure 12 includes a mounting frame 121 mounted on the inner surface of the sliding section 1122 and a heating element 122 protruded from the mounting frame 121 away from the sleeve 11. The heating element 122 is at least partially protruded from the connection end of the sleeve 11. More specifically, the mounting frame 121 is mounted on the sleeve 11 near one end of the movable member 13. More specifically, the mounting frame 12 is fixedly mounted on the inner surface of the sliding section 1122 near one end of the movable member 13. It can be understood that in other embodiments not shown, the sleeve 11 is roughly columnar or cylindrical, and the heating structure 12 includes a heating element 122, which is connected to the sleeve 11 and at least partially protruded from the connection end of the sleeve 11. In order to improve the efficiency of heat conduction between the heating element 122 and the tobacco product 20, the shape of the heating element 122 is designed so that the heating element 122 has a larger specific surface area. In the present embodiment, the heating element 122 is in the form of a sheet. It can be understood that in other embodiments not shown, the heating element 122 can also be in a columnar shape or other shape that is convenient for placing the tobacco product 20.

The two ends of the movable member 13 are connected, and a limiting plate 131 is provided on the inner surface of the movable member 13. The limiting plate 131 divides the inner cavity of the movable member 13 into a connecting cavity 1312 for accommodating the mounting portion 112 and an atomizing cavity 1313 for placing the tobacco product 20. The inner diameter of the movable member 13 in the connecting cavity 1312 is larger than the outer diameter of the mounting portion 112. The limiting plate 131 is provided with a limiting hole 1311 corresponding to the shape of the heating element 122. It can be understood that in other embodiments not shown In the embodiment, no limiting plate 131 is provided on the inner surface of the movable part 13. When the limiting plate 131 is omitted, the two ends of the movable part 13 are connected, and the inner cavity of the movable part 13 is used for accommodating the mounting portion 112 and placing the tobacco product 20. At this time, a protrusion 135 for abutting against the tobacco product 20 can be provided on the inner wall of the movable part 13. When the movable part 13 and the sleeve 11 are separated, the tobacco product 20 can be separated from the heating element 122 due to the abutment between the tobacco product 20 and the protrusion 135 on the movable part 13. An internal thread segment 132 corresponding to the external thread segment 1123 is arranged on the inner surface of one end of the movable part 13 close to the sleeve 11 along the circumference of the movable part 13. In the present embodiment, the end of the movable part 13 facing the sleeve 11 is the connecting end of the movable part 13. Along the axial direction of the electronic cigarette suction device 10, at least one positioning rib 133 corresponding to the slide groove 1124 is convexly provided on the cavity wall of the movable part 13 on the side of the internal thread segment 132 away from the sleeve 11, and at least one positioning rib 133 corresponding to the slide groove 1124 is convexly provided on the cavity wall between the internal thread segment 132 and the limiting plate 131. In the present embodiment, there are four positioning ribs 133, and the four positioning ribs 133 are evenly distributed on the inner surface of the movable part 13 along the circumference of the movable part 13. A hollow groove 134 is opened on the cavity wall between the internal thread section 132 and the positioning rib 133 along the circumference of the movable part 13, and the inner diameter of the hollow groove 134 is larger than the inner diameter of the internal thread section 132 and larger than the outer diameter of the external thread section 1123. In this embodiment, the inner diameter of the hollow groove 134 is the same as the inner diameter of the movable part 13 in the connecting cavity 1312 section. When the movable part 13 is installed on the mounting portion 112, the empty groove 134 is used to prevent the internal thread section 132 from rotating to the bottom of the external thread section 1123. The term "bottom" used here refers to the end of each part of the electronic cigarette suction device 10 in the axial direction of the electronic cigarette suction device 10 away from the movable part 13. The external thread section 1123 interferes with the positioning rib 133 entering the slide groove 1124, making it difficult for the positioning rib 133 to align with the slide groove 1124; by providing the empty groove 134, when the internal thread section 132 gradually rotates to the bottom of the external thread section 1123, the external thread section 1123 gradually enters the empty groove 134, When the internal thread section 132 is completely rotated to the bottom of the external thread section 1123, the threaded fit between the internal thread section 132 and the external thread section 1123 is released, and the external thread section 1123 is completely accommodated in the empty groove 134, giving the positioning rib 133 space to align with the slide groove 1124. After the positioning rib 133 is aligned with the slide groove 1124, the protruding positioning rib 133 gradually slides into the corresponding slide groove 1124. At this time, since the inner diameter of the movable part 13 in the connecting cavity 1312 is larger than the outer diameter of the mounting portion 112, the inner surface of the movable part 13 will not contact the outer surface of the external thread section 1123 during the sliding process. Before the positioning rib 133 slides into the slide groove 1124, the heating element 122 does not penetrate into the limiting hole 1311, and the protruding positioning rib 133 gradually slides into the corresponding slide groove 1124. The heating element 122 gradually passes through the limiting hole 1311. When the positioning rib 133 completely slides into the slide groove 1124, the heating element 122 completely passes through the limiting hole 1311. At this time, the heating element 122 is exposed to the maximum extent, which is convenient for the user to place the tobacco product 20 firmly on the heating element 122. When the movable part 13 gradually separates from the mounting portion 112, the positioning rib 133 gradually separates from the slide groove 1124, and the external thread section 1123 gradually enters the empty groove 134. When the positioning rib 133 completely separates from the slide groove 1124, the heating element 122 passes through the limiting hole 1311, and the external thread section 1123 is completely accommodated in the empty groove 134. At this time, the internal thread section 132 can be gradually screwed to the end of the external thread section 1123. The term "end" used here refers to the end of each part of the electronic cigarette suction device 10 that is away from the sleeve 11 in the axial direction of the electronic cigarette suction device 10, so that the movable part 13 The movable part 13 is separated from the mounting portion 112, and a blank groove 134 is provided to ensure that the internal thread section 132 and the external thread section 1123 will not contact each other before the positioning rib 133 is completely separated from the slide groove 1124, to prevent part of the positioning rib 133 from being located in the corresponding slide groove 1124 when the internal thread section 132 and the external thread section 1123 are in contact, so that the positioning rib 133 and the slide groove 1124 cannot be further separated, and the part of the positioning rib 133 located in the corresponding slide groove 1124 interferes with the rotation of the internal thread section 132 along the external thread section 1123, so that the movable part 13 cannot be separated from the mounting portion 112.

The length of the reserved section 1121 in the axial direction of the electronic cigarette suction device 10 is not less than the length between the bottom of the movable part 13 and the bottom of the positioning rib 133, so that the positioning rib 133 can slide in the slide groove 1124 to the maximum extent. In this embodiment, the internal thread section 132 is arranged at the bottom of the movable part 13, and the length of the reserved section 1121 in the axial direction of the electronic cigarette suction device 10 is not less than the sum of the length of the internal thread section 132 and the length of the empty groove 134.

The length of the slide groove 1124 in the axial direction of the electronic cigarette suction device 10 is not less than the length between the bottom of the positioning rib 133 and the bottom of the limiting plate 131, so that the heating element 122 can pass through the limiting hole 1311 to the maximum extent, so that the heating element 122 is exposed to the maximum extent. In this embodiment, the end of the positioning rib 133 and the bottom of the limiting plate 131 are at the same position, and the length of the slide groove 1124 in the axial direction of the electronic cigarette suction device 10 is not less than the length of the positioning rib 133. It can be understood that in the case where the limiting plate 131 is not provided, the length of the slide groove 1124 in the axial direction of the electronic cigarette suction device 10 is not less than the length of the positioning rib 133, so that the positioning rib 133 does not affect the insertion of the tobacco product 20.

The length of the empty groove 134 in the axial direction of the electronic cigarette suction device 10 is greater than the length between the end of the sleeve 11 and the bottom of the external thread section 1123. When the internal thread section 132 is gradually rotated to the bottom of the external thread section 1123, the external thread section 1123 gradually enters the empty groove 134. When the internal thread section 132 is completely rotated to the bottom of the external thread section 1123, the threaded fit between the internal thread section 132 and the external thread section 1123 is released, and the external thread section 1123 is completely accommodated in the empty groove 134, giving the positioning rib 133 an alignment with the slide groove 11 24, when the positioning rib 133 is aligned with the slide groove 1124, the protruding positioning rib 133 gradually slides into the corresponding slide groove 1124, thereby preventing part of the positioning rib 133 from being located in the corresponding slide groove 1124 when the internal thread section 132 is completely rotated to the bottom of the external thread section 1123, so that the positioning rib 133 and the slide groove 1124 cannot be further separated, and the part of the positioning rib 133 located in the corresponding slide groove 1124 interferes with the rotation of the internal thread section 132 along the external thread section 1123, so that the movable part 13 cannot be separated from the sleeve 11.

When the positioning rib 133 slides into the slide groove 1124, the length from the connecting end of the sleeve 11 to the bottom of the limiting plate 131 in the axial direction of the electronic cigarette suction device 10 is not less than the length from the connecting end of the sleeve 11 to the end of the heating element 122 away from the connecting end of the sleeve 11.

In this embodiment, the length from the bottom of the positioning rib 133 to the bottom of the limiting plate 131 in the axial direction of the electronic cigarette suction device 10 is not less than the length between the end of the sleeve 11 and the end of the heating element 122, so that before the positioning rib 133 is separated from the slide groove 1124, the heating element 122 has been completely separated from the limiting hole 1311, so as to avoid the heating element 122 from being damaged due to not completely separating from the limiting hole 1311 when the movable part 13 can rotate relative to the sleeve 11. Specifically, the bottom of the heating element 122 is at the same position as the end of the sleeve 11, and the end of the positioning rib 133 is at the same position as the bottom of the limiting plate 131, and the length of the positioning rib 133 in the axial direction of the electronic cigarette suction device 10 is not less than the length of the heating element 122. It can be understood that in the case where the limiting plate 131 is not provided, the length of the slide groove 1124 in the axial direction of the electronic cigarette suction device 10 is not less than the length of the positioning rib 133, so that the positioning rib 133 does not affect the insertion of the tobacco product 20.

During use, the tobacco article 20 is placed on the heating element 122, and the heating element 122 can heat the atomized tobacco article 20 to form smoke.

Installation process: When the user needs to install the movable part 13 on the sleeve 11, the internal thread section 132 on the movable part 13 is gradually rotated to the bottom of the external thread section 1123, and the external thread section 1123 gradually enters the empty groove 134. When the internal thread section 132 is completely rotated to the bottom of the external thread section 1123, the external thread section 1123 is completely accommodated in the empty groove 134. At this time, the positioning rib 133 is aligned with the corresponding slide groove 1124. When the positioning rib 133 is aligned with the slide groove 1124, the protruding positioning rib 133 gradually slides into the corresponding slide groove 1124. When the positioning rib 133 does not slide into Before the corresponding slide groove 1124, the heating element 122 has not penetrated into the limiting hole 1311. At this time, since the inner diameter of the movable part 13 is larger than the outer diameter of the mounting portion 112, the inner surface of the movable part 13 will not contact the outer surface of the external threaded section 1123 during the sliding process, and the heating element 122 gradually passes through the limiting hole 1311. When the positioning rib 133 completely slides into the slide groove 1124, the heating element 122 completely passes through the limiting hole 1311. At this time, the heating element 122 is exposed to the maximum extent, and the user can firmly place the tobacco product 20 into the atomization chamber 1313 on the heating element 122.

Usage process: When the user needs to separate the tobacco product 20 from the heating element 122, the user slides the movable part 13 along the axial direction of the electronic cigarette suction device 10 in the direction away from the sleeve 11, and the positioning rib 133 gradually separates from the slide groove 1124, and the external thread section 1123 gradually enters the empty groove 134. At this time, the heating element 122 gradually separates from the limiting hole 1311, and the tobacco product 20 arranged on the heating element 122 gradually abuts against the end surface of the limiting plate 131; as the positioning rib 133 completely separates from the slide groove 1124, the external thread section 1123 is completely accommodated in the empty groove 134, the heating element 122 completely separates from the limiting hole 1311, the limiting plate 131 separates the tobacco product 20 and the heating element 122, the tobacco product 20 separates from the heating element 122, and then the tobacco product 20 is taken out of the atomization chamber 1313. When the user needs to clean the dirt on the heating element 122, the user can gradually rotate the internal thread section 132 to the end of the external thread section 1123 to gradually separate the movable part 13 from the mounting portion 112. At this time, since the movable part 13 is arranged outside the heating element 122, the movable part 13 can prevent the heating element 122 from being damaged when it is completely separated from the limiting hole 1311 and gradually exposed to the outside. When the heating element 122 is completely exposed to the outside, the user can clean the dirt on the heating element 122 and the tobacco product 20 debris at the bottom of the heating element 122.

The electronic cigarette suction device 10 of the present invention or the electronic cigarette using the electronic cigarette suction device 10, because the movable part 13 is detachably connected to the end of the sleeve 11 close to the heating structure 12, the mounting frame 121 is mounted on one end of the sleeve 11, and the heating element 122 is protrudingly arranged on the mounting frame 121 at the end away from the sleeve 11, and a limiting plate 131 is provided on the inner surface of the movable part 13, and a limiting hole 1311 corresponding to the heating element 122 is opened on the limiting plate 131; when the movable part 13 and the sleeve 11 are connected, the tobacco product 20 can be placed in the limiting hole 1311 provided in the limiting hole 1311. When the tobacco product 20 in the movable part 13 needs to be taken out, the movable part 13 is slid. When the heating part 122 is separated from the limiting hole 1311, the tobacco product 20 can be abutted against the limiting plate 131 and then separated from the heating part 122. Then, the heating part 122 is taken out from the movable part 13. The movable part 13 and the sleeve 11 are kept in connection. The movable part 13 prevents the heating part 122 from being damaged when it is exposed to the outside. For the user's conventional needs of taking out the tobacco product 20 and preventing the heating part from being damaged, the user only needs to slide the movable part 13. 122 and the bottom of the heating element 122 are at least partially exposed to the outside world, so that it is convenient for the user to clean the heating element 122 and the debris of the tobacco product 20 at the bottom of the heating element 122. In addition to the conventional need to take out the tobacco product 20, if the user wants to try to expose the heating element 122 and directly clean the heating element 122 and the debris of the tobacco product 20 at the bottom of the heating element 122, the user needs to further rotate the movable part 13 on the basis of sliding the movable part 13 until it is completely disconnected from the sleeve 11. The two-step operation of sliding the movable part 13 and further rotating the movable part 13 not only provides the user with the possibility of cleaning the heating element 122 and the debris of the tobacco product 20 at the bottom of the heating element 122, but also increases the difficulty of the user exposing the heating element 122. The increased difficulty of operation can serve as a risk warning to the user that exposing the heating element 122 may cause damage to the heating element 122.
