[0040] In the electronic cigarette with a replaceable oil bottle of the present utility model, by pushing the plugging member to move in the oil bottle connection cylinder through the atomization connection cylinder, the process of oil passage is lengthened, making the process of oil passage easier to control; when the plugging member detaches from the oil bottle connection cylinder, the atomization connection cylinder and the oil bottle connection cylinder are hermetically sleeved, and the e-liquid in the oil supply cavity thus flows into the atomization connection cylinder and is guided by the atomization connection cylinder into the oil storage cavity, and it is not easy to leak from between the atomizer and the oil bottle; the sleeving of the atomization connection cylinder and the oil bottle connection cylinder also improves the stability of the connection between the atomizer and the oil bottle.

[0041] The following will mainly describe the specific structure of the electronic cigarette with a replaceable oil bottle.

[0042] Please refer to Figures 1 to 3 , the electronic cigarette 100 of the present utility model may include an atomizer 110.

The oil bottle 120 may be provided with an oil supply port 122, and the oil supply port 122 may communicate with the oil supply cavity 121, so that the e-liquid in the oil supply cavity 121 can flow out through the oil supply port 122.

[0044] Please refer to Figures 1 to 3, the electronic cigarette 100 of the present utility model may include an atomization connection assembly 130. The atomization connection assembly 130 may include an atomization connection cover 131. The atomization connection cover 131 may be connected to cover the oil inlet 112, that is, the atomization connection cover 131 may close the oil inlet 112 by connecting to the cavity wall of the oil storage cavity 111. The atomization connection cover 131 and the cavity wall of the oil storage cavity 111 may be integrally formed, whereby the atomization connection cover 131 and the cavity wall of the oil storage cavity 111 are tightly connected and it is not easy to leak e-liquid. The atomization connection cover 131 and the cavity wall of the oil storage cavity 111 may also be detachably connected, such as by snap connection, screw connection, socket connection or bonding, etc., which is convenient for preparation and assembly. The atomization connection cover 131 may be made of a rigid material (such as plastic, metal or wood, etc.) or an elastic material (such as silica gel, rubber or plastic, etc.), without specific limitation.

[0045] Please refer to Figures 1 to 3 , the atomization connection assembly 130 may include an atomization connection cylinder 132. The atomization connection cylinder 132 may be inserted through the atomization connection cover 131. In other words, the atomization connection cylinder 132 may communicate with the oil storage cavity 111. The atomization connection cover 131 and the atomization connection cylinder 132 may be integrally formed, whereby the atomization connection cover 131 and the atomization connection cylinder 132 are tightly connected and it is not easy to leak e-liquid. The atomization connection cover 131 and the atomization connection cylinder 132 may also be detachably connected, such as by snap connection, screw connection, socket connection or bonding, etc., which is convenient for preparation and assembly. The atomization connection cylinder 132 may also be made of a rigid material or an elastic material. The atomization connection cylinder 132 may extend in a direction away from the atomizer 110, that is, when the atomization connection cover 131 is connected to the cavity wall of the oil storage cavity 111, the atomizer 110 and the atomization connection cylinder 132 may be located on opposite sides of the atomization connection cover 131 respectively.

[0046] Please refer to Figures 1 to 3 , the electronic cigarette 100 of the present utility model may include an oil bottle connection assembly 140. The oil bottle connection assembly 140 may include an oil bottle connection cover 141. The oil bottle connection cover 141 may be connected to cover the oil supply port 122, that is, the oil bottle connection cover 141 may close the oil supply port 122 by connecting to the cavity wall of the oil supply cavity 121. The oil bottle connection cover 141 and the cavity wall of the oil supply cavity 121 may also be integrally formed or detachably connected. The oil bottle connection cover 141 may also be made of a rigid material or an elastic material.

[0047] Please refer to Figure 2 , in an embodiment, the electronic cigarette 100 of the present utility model may include a first seal 191. The first seal 191 may be in a ring shape or a tubular shape. The first seal 191 may be located between the oil bottle connection cover 141 and the cavity wall of the oil supply cavity 121 to seal and connect the oil bottle connection cover 141 and the cavity wall of the oil supply cavity 121.

[0048] The oil bottle connection assembly 140 may include an oil bottle connection cylinder 142. The oil bottle connection cylinder 142 may be inserted through the oil bottle connection cap 141, that is, the oil bottle connection cylinder 142 may communicate with the oil supply chamber 121. The oil bottle connection cap 141 and the oil bottle connection cylinder 142 may be integrally formed or detachably connected. The oil bottle connection cylinder 142 may also be made of a rigid material or an elastic material.

[0049] Please refer to Figures 1 to 3 , in some embodiments, one end of the oil bottle connection cylinder 142 close to the atomization connection cylinder 132 may be located inside the oil bottle connection cap 141. With this arrangement, when the atomizer 110 and the oil bottle 120 are assembled, the atomization connection cap 131 and the oil bottle connection cap 141 can abut against each other, and the connection between the atomizer 110 and the oil bottle 120 is more compact. Specifically, one end of the oil bottle connection cylinder 142 close to the atomization connection cylinder 132 may be flush with the oil bottle connection cap 141. Of course, the oil bottle connection cap 141 may be provided with a connection groove 144 (such as Figure 2 shown), and one end of the oil bottle connection cylinder 142 close to the atomization connection cylinder 132 may also be located in the middle of the connection groove 144 or at one end of the connection groove 144 close to the oil supply chamber 121.

[0050] The present utility model does not limit the extending direction of the oil bottle connection cylinder 142. One end of the oil bottle connection cylinder 142 away from the oil bottle connection cap 141 may extend in a direction away from the oil bottle 120 or may extend towards the oil bottle 120. Of course, both ends of the oil bottle connection cylinder 142 may also be flush with the oil bottle connection cap 141, that is, the length of the oil bottle connection cylinder 142 may be the same as the thickness of the oil bottle connection cap 141.

[0051] In some embodiments, the electronic cigarette 100 may further include an elastic member 180. The elastic member 180 may be in a ring shape or a cylinder shape. The elastic member 180 may be made of materials such as silica gel, rubber, or plastic. When the atomization connection cylinder 132 is connected to the oil bottle connection cylinder 142, the elastic member 180 may be located between the atomization connection cylinder 132 and the oil bottle connection cylinder 142 to seal the connection between the atomization connection cylinder 132 and the oil bottle connection cylinder 142, so that the e-liquid is not easily leaked from the gap between the atomization connection cylinder 132 and the oil bottle connection cylinder 142.

[0052] Specifically, the elastic member 180 may be sleeved on the atomization connection cylinder 132. When the atomization connection cylinder 132 is inserted into the oil bottle connection cylinder 142, the outer peripheral wall of the elastic member 180 can be sealingly connected to the inner wall of the oil bottle connection cylinder 142. The elastic member 180 may also be connected to the inner peripheral wall of the oil bottle connection cylinder 142. When the atomization connection cylinder 132 is inserted into the oil bottle connection cylinder 142, the inner peripheral wall of the elastic member 180 can be sealingly connected to the outer peripheral wall of the atomization connection cylinder 132.

[0053] Please refer to Figure 3, the elastic member 180 and the oil bottle connecting cylinder 142 can be integrally formed. At this time, the oil bottle connecting cylinder 142 can be made of an elastic material. Of course, the elastic member 180 and the oil bottle connecting cylinder 142 can also be detachably connected. The elastic member 180 and the atomizing connecting cylinder 132 can also be integrally formed or detachably connected.

[0054] Please refer to Figure 2 and Figure 3 , the electronic cigarette 100 of the present utility model may further include a plugging member 150. The plugging member 150 can be inserted into the oil bottle connecting cylinder 142 and be hermetically connected to the oil bottle connecting cylinder 142. Thus, the e-liquid in the oil supply cavity 121 will not flow out through the oil bottle connecting cylinder 142. The plugging member 150 can be made of an elastic material, such as silica gel, rubber or plastic material. The plugging member 150 can also be made of a hard material, and the plugging member 150 is in interference connection with the oil bottle connecting cylinder 142.

[0055] Please refer to Figure 2 , the plugging member 150 can be columnar, and the plugging member 150 can extend in the length direction of the oil bottle connecting cylinder 142. With such a setting, the contact area between the plugging member 150 and the oil bottle connecting cylinder 142 can be increased, and the sealing effect of the plugging member 150 on the oil bottle connecting cylinder 142 is relatively good.

[0056] In some embodiments, under the drive of an external force (such as manual), the atomizing connecting cylinder 132 can be inserted into the oil bottle connecting cylinder 142, that is, the atomizing connecting cylinder 132 and the oil bottle connecting cylinder 142 can have an axial relative displacement. The atomizing connecting cylinder 132 and the oil bottle connecting cylinder 142 can both move towards each other, or either one of them can move while the other remains in place. The end of the atomizing connecting cylinder 132 away from the atomizing connecting cap 131 can abut against the plugging member 150 so that the plugging member 150 can move in the oil bottle connecting cylinder 142 and fall off into the oil supply cavity 121. The atomizing connecting cylinder 132 and the oil bottle connecting cylinder 142 can be hermetically connected. Thus, by pushing the plugging member 150 to move in the oil bottle connecting cylinder 142 through the atomizing connecting cylinder 132, the process of oil supply is lengthened, making the process of oil supply easier to control; when the plugging member 150 detaches from the oil bottle connecting cylinder 142, the atomizing connecting cylinder 132 and the oil bottle connecting cylinder 142 are hermetically connected, and the e-liquid in the oil supply cavity 121 thus flows into the atomizing connecting cylinder 132 and is guided by the atomizing connecting cylinder 132 into the oil storage cavity 111, and is not likely to leak between the atomizer 110 and the oil bottle 120; the connection between the atomizing connecting cylinder 132 and the oil bottle connecting cylinder 142 also improves the connection stability between the atomizer 110 and the oil bottle 120.

[0057] The outer peripheral wall of the atomizing connecting cylinder 132 and the inner peripheral wall of the oil bottle connecting cylinder 142 can be hermetically connected all the time during their relative displacement, thereby being able to reduce the probability of e-liquid leakage caused by the movement of the plugging member 150.

[0058] The atomizing connection cylinder 132 can also be hermetically sleeved with the oil bottle connection cylinder 142 after it is inserted into the oil bottle connection cylinder 142 by a certain length. Specifically, please refer to Figure 1 and Figure 2 . In one embodiment, one end of the atomizing connection cylinder 132 away from the atomizing connection cover 131 can be frustum-shaped. As the length of the atomizing connection cylinder 132 inserted into the oil bottle connection cylinder 142 increases, the atomizing connection cylinder 132 can be hermetically connected to the oil bottle connection cylinder 142. Such a setting also facilitates the insertion of the atomizing connection cylinder 132 into the oil bottle connection cylinder 142. In another embodiment, the oil bottle connection cylinder 142 can be tapered in its extending direction. As the length of the atomizing connection cylinder 132 inserted into the oil bottle connection cylinder 142 increases, one end of the atomizing connection cylinder 132 away from the atomizing connection cover 131 can also be hermetically sleeved with the oil bottle connection cylinder 142, and it also facilitates the insertion of the atomizing connection cylinder 132 into the oil bottle connection cylinder 142.

[0059] The atomizing connection cylinder 132 and the oil bottle connection cylinder 142 can also be hermetically sleeved after the blocking member 150 is detached from the oil bottle connection cylinder 142. For example, a sealing member that expands upon contact with liquid can be provided on the atomizing connection cylinder 132. When the blocking member 150 is detached from the oil bottle connection cylinder 142, the sealing member encounters the e-liquid in the oil supply chamber 121 and expands in volume, capable of sealing the gap between the atomizing connection cylinder 132 and the oil bottle connection cylinder 142. Alternatively, an umbrella-shaped opening and closing member (not shown) can be provided at one end of the atomizing connection cylinder 132 away from the atomizing connection cover 131. When the blocking member 150 is detached from the oil bottle connection cylinder 142 and the atomizing connection cylinder 132 continues to advance towards the oil supply chamber 121, the umbrella-shaped opening and closing member is no longer blocked by the oil bottle connection cylinder 142 and radially expands. The expanded umbrella-shaped opening and closing member can prevent the e-liquid from flowing out through the gap between the atomizing connection cylinder 132 and the oil bottle connection cylinder 142.

[0060] The number of the atomizing connection cylinders 132 and the oil bottle connection cylinders 142 can each be one. Please refer to Figures 1 to 3 . The number of the atomizing connection cylinders 132 and the oil bottle connection cylinders 142 can also be at least two, and the number of the atomizing connection cylinders 132 and the oil bottle connection cylinders 142 can be equal. At least two atomizing connection cylinders 132 / oil bottle connection cylinders 142 can be arranged at intervals.

[0061] Please refer to Figure 2 . The electronic cigarette 100 of the present utility model can also include a positioning post 160. The positioning post 160 can be provided on any one of the atomizing connection cover 131 and the oil bottle connection cover 141. Please refer to Figure 2, the electronic cigarette 100 may further include a positioning groove 170, which may be provided on the remaining one of the atomization connection cover 131 and the oil bottle connection cover 141. The positioning groove 170 and the positioning post 160 may be adaptively arranged, and the positioning post 160 can be inserted into the positioning groove 170. When the positioning post 160 is located in the positioning groove 170, the positioning post 160 may abut against the groove wall of the positioning groove 170. Of course, there may also be a gap between the positioning post 160 and the groove wall of the positioning groove 170, which is not limited.

[0062] In the electronic cigarette 100 of the present utility model, when the atomization connection cylinder 132 is inserted into the oil bottle connection cylinder 142 under the drive of an external force, the positioning post 160 is inserted into the positioning groove 170. The settings of the positioning post 160 and the positioning groove 170 can play a role in assisting positioning and guiding the connection between the atomization connection cylinder 132 and the oil bottle connection cylinder 142, and at the same time can also strengthen the connection effect between the atomizer 110 and the oil bottle 120.

[0063] Under the drive of an external force, the positioning post 160 may first enter the positioning groove 170, and then the atomization connection cylinder 132 enters the oil bottle connection cylinder 142; or the atomization connection cylinder 132 may enter the oil bottle connection cylinder 142 while the positioning post 160 enters the positioning groove 170. In this way, the functions of assisting positioning and guiding of the positioning post 160 and the positioning groove 170 can be realized. The above effects can be achieved by setting the length of the positioning post 160 to be greater than or equal to the length of the atomization connection cylinder 132.

[0064] The present utility model does not specifically limit the positions and extension directions of the positioning post 160 and the positioning groove 170, as long as the positioning post 160 and the positioning groove 170 can achieve the functions of assisting positioning and guiding.

[0065] For example, please refer to Figure 1 and Figure 2, in one embodiment, the positioning post 160 can be provided on the atomization connection cover 131, and the positioning post 160 and the atomization connection cylinder 132 can be located on the same side of the atomization connection cover 131. At this time, the positioning groove 170 can be formed to protrude from the oil bottle connection cover 141 toward the oil supply chamber 121, that is, one end of the positioning groove 170 connecting the oil bottle connection cover 141 can be open, and one end of the positioning groove 170 away from the oil bottle connection cover 141 can be closed, so that the positioning groove 170 can be adaptively connected to the positioning post 160. In this way, both the positioning post 160 and the atomization connection cylinder 132 protrude from the surface of the atomization connection cover 131 and extend toward the oil bottle connection cover 141 (when the atomizer 110 and the oil bottle 120 are in a connected state). The positioning post 160 and the positioning groove 170 have a relatively good effect of assisting in positioning and guiding, and it is easier for the user to align and insert the atomization connection cylinder 132 into the oil bottle connection cylinder 142. Moreover, when the atomizer 110 and the oil bottle 120 are connected, the free ends of the positioning post 160, the positioning groove 170, the atomization connection cylinder 132, and the oil bottle connection cylinder 142 all face the direction of the oil supply chamber 121, and the atomization connection cover 131 and the oil bottle connection cover 141 are in contact, so that the overall structure of the electronic cigarette 100 is relatively compact.

[0066] For another example, in some other embodiments, the positioning post 160 can be provided on the oil bottle connection cover 141, and one end of the positioning post 160 away from the oil bottle connection cover 141 can extend in a direction away from the oil supply chamber 121. At this time, the positioning groove 170 can be protrudingly provided on the atomization connection cover 131, one end of the positioning groove 170 away from the atomization connection cover 131 can be open, and one end of the positioning groove 170 connecting the atomization connection cover 131 can be closed, and the positioning post 160 can be inserted into the positioning groove 170 through the open end. In this case, one end of the oil bottle connection cylinder 142 away from the oil bottle connection cover 141 can also extend in a direction away from the oil supply chamber 121, that is, when the atomizer 110 and the oil bottle 120 are connected, the positioning post 160, the positioning groove 170, the atomization connection cylinder 132, and the oil bottle connection cylinder 142 are all located between the atomization connection cover 131 and the oil bottle connection cover 141. Of course, the above settings can also achieve the function of the positioning post 160 and the positioning groove 170 assisting in positioning and guiding.

[0067] The positioning post 160 and the positioning groove 170 can be adaptively arranged. The cross-sectional shapes of the positioning post 160 and the positioning groove 170 can be the same, which is more convenient for inserting the positioning post 160 into the positioning groove 170. The cross-sectional shapes of the two can also be different, so that the positioning post 160 is not likely to rotate undesirably in the positioning groove 170, and the positioning post 160 and the positioning groove 170 have a relatively good effect of assisting in positioning and guiding.

[0068] The number of the positioning posts 160 and the positioning grooves 170 can be equal. The number of the positioning posts 160 can be one. When the number of the positioning posts 160 is one, the cross-section of the positioning post 160 can be non-circular, and the cross-section of the positioning groove 170 can also be non-circular. In this way, the positioning post 160 is not likely to rotate undesirably within the positioning groove 170, so that the effect of auxiliary positioning and guiding of the two is relatively good.

[0069] Please refer to Figure 2 , the number of the positioning posts 160 and the positioning grooves 170 can be at least two respectively. Thus, through the positioning of at least two positioning points (mathematical concept), the positioning of the positioning posts 160 and the positioning grooves 170 is more accurate, the connection between the atomizing connection cylinder 132 and the oil bottle connection cylinder 142 is easier, and the connection between the atomizer 110 and the oil bottle 120 is also relatively firm. When the number of the positioning posts 160 and the positioning grooves 170 is at least three, at least three positioning posts 160 (or positioning grooves 170) can be arranged at equal or unequal intervals, and the effect of improving the positioning accuracy and enhancing the connection can also be achieved.

[0070] In the electronic cigarette 100 of the present utility model, after the atomizer 110 and the oil bottle 120 are assembled, the atomizer 110 and the oil bottle 120 can be arranged vertically or horizontally, and both can achieve the oil supply from the oil bottle 120 to the atomizer 110.

[0071] Please refer to Figures 1 to 3 , in some embodiments, after the atomizing connection cylinder 132 is sleeved with the oil bottle connection cylinder 142, the oil bottle 120 can be located above the atomizer 110. Thus, the e-liquid in the oil supply cavity 121 is affected by gravity and spontaneously flows from the oil bottle connection cylinder 142 into the oil storage cavity 111 of the atomizer 110, and the effect of refueling is relatively good.

[0072] The atomizer 110 can be formed with an atomizing cavity communicating with the oil storage cavity 111. The atomizer 110 can include a smoke outlet pipe 113, and one end of the smoke outlet pipe 113 can communicate with the atomizing cavity. Please refer to 2 and Figure 3 , in some embodiments, the oil bottle 120 can be formed with a clearance through groove 123, the oil bottle connection cap 141 can be provided with an avoidance through hole 143 communicating with the clearance through groove 123, and the hole wall of the avoidance through hole 143 can be connected to the groove wall of the clearance through groove 123. When the atomizing connection cylinder 132 is connected to the oil bottle connection cylinder 142, the smoke outlet pipe 113 can pass through the avoidance through hole 143 and be inserted into the clearance through groove 123. Thus, the smoke in the atomizing cavity can be discharged through the smoke outlet pipe 113 and finally inhaled by the user, and at the same time, the overall structure of the electronic cigarette 100 is more compact.

[0073] Please refer to again Figure 2, the electronic cigarette 100 may include a second seal 192. The second seal 192 may be annular or tubular, and the second seal 192 may be sleeved outside the smoke outlet pipe 113 to hermetically connect the smoke outlet pipe 113 and the groove wall of the clearance groove 123, thereby making the connection between the atomizer 110 and the oil bottle 120 more firm.

[0074] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied to other related technical fields, is included in the patent protection scope of the present invention.
