Description

Technical Field

[0001] The present invention relates to the technical field of simulated smoking, and in particular to a cigarette cartridge and an electronic cigarette using the cigarette cartridge. Background Art

[0002] At present, electronic cigarettes have become a relatively mature substitute for smoking on the market. They use batteries to power the heating unit in the cigarette cartridge, so that the heating unit heats the smoke liquid under electrical drive to produce smoke for users to inhale.

[0003] In a traditional liquid-fillable atomizer, the liquid inlet hole on the atomizer shell is usually connected to the liquid storage chamber. When the electronic cigarette is not used for a long time, the smoke liquid in the liquid storage chamber can enter the atomizer shell through the liquid inlet hole, and the liquid absorption part in the atomizer shell can gradually absorb the smoke liquid entering the atomizer shell. However, the inner cavity of the atomizer shell is usually connected to the outside world. The smoke liquid absorbed by the liquid absorption part evaporates to the outside world, and long-term contact with air may cause the smoke liquid to deteriorate, so that the liquid absorption part can repeatedly absorb the smoke liquid entering the atomizer shell. When the user uses the electronic cigarette again, part of the smoke liquid in the liquid storage chamber has been absorbed by the liquid absorption part, and the amount of smoke liquid in the liquid storage chamber is reduced, making it difficult to store the smoke liquid in the liquid storage chamber, and even causing a waste of money.

[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0044] Embodiment 1

[0045] Please see Figure 1 The first embodiment of the present invention provides an electronic cigarette, which includes a cigarette cartridge 10 and a battery device (not shown). The cigarette cartridge 10 is used to be electrically connected to the battery device. The cigarette cartridge 10 heats the cigarette liquid under the electrical drive of the battery device, so that the cigarette liquid is atomized into smoke.

[0046] The cigarette cartridge 10 includes a cigarette cartridge body 11 and a sealing structure 12 installed at the lower end of the cigarette cartridge body 11. Figure 2-7 The cartridge body 11 includes a cartridge housing 111, a movable structure 112 and an atomization structure 113 contained in the cartridge housing 111. In this embodiment, the sealing structure 12 and the cartridge body 11 are independent parts, while in another embodiment not shown, the sealing structure 12 can be integrally formed with the cartridge housing 111.

[0047] In one embodiment, the cartridge shell 111 is roughly cylindrical with an open lower end. The inner cavity of the cartridge shell 111 forms a liquid storage chamber 1111. The upper end of the cartridge shell 111 is provided with a vent hole 1112 at the end of the cartridge shell 111 for allowing one end of the movable structure 112 to pass through, a liquid injection hole 1113 connected to the liquid storage chamber 1111, and an air inlet hole 1114 on the side wall of the cartridge shell 111.

[0048] In another embodiment not shown, the injection hole 1113 is not provided on the cartridge shell 111. Instead, the smoke liquid is injected into the cartridge 10 from the lower end of the cartridge shell 111 in a pre-packaged manner. When the smoke liquid is consumed, the cartridge 10 is discarded as a whole, and a non-refillable smoke cartridge 10 is provided. On the inner wall of the cigarette cartridge housing 111 near the vent hole 1112, it protrudes downward along the axial direction of the cigarette cartridge housing 111 to form a limiting portion 1115 that can abut against the movable structure 112. A smoke liquid plug 1116 is provided in the injection hole 1113. In the present embodiment, the smoke liquid plug 1116 is made of rubber material. It can be understood that in other embodiments not shown, the smoke liquid plug 1116 can also be made of other materials with good sealing properties such as silicone. When the user has finished filling the liquid storage chamber 1111 with smoke liquid through the injection hole 1113, the smoke liquid plug 1116 is installed in the injection hole 1113. The smoke liquid plug 1116 can seal the injection hole 1113 to prevent the smoke liquid in the liquid storage chamber 1111 from leaking from the injection hole 1113.

[0049] See also Figure 2-Figure 5 An air inlet 1114 is provided at the lower side of the cartridge housing 111, and external air enters the cartridge 10 from the air inlet 1114. The number of the air inlet 1114 may be N, where N is a natural number greater than or equal to one, and the distance between the N air inlet holes 1114 depends on the specific design. It can be understood that in other embodiments not shown, the air inlet 1114 may also be provided at the top, upper side, or bottom of the cartridge housing 111.

[0050] The movable structure 112 includes an isolation guide tube 1121 at least partially disposed in the storage portion 1115 and a movable tube 1122 movably disposed in the isolation guide tube 1121 . The isolation guide tube 1121 is connected at both ends.

[0051] See also Figure 2 , Figure 6 as well as Figure 7 The isolation guide tube 1121 is made of stainless steel. It can be understood that in other embodiments not shown, the isolation guide tube 1121 can also be made of other materials with higher hardness such as titanium alloy. The inner cavity of the isolation guide tube 1121 is connected to the vent hole 1112. The isolation guide tube 1121 includes a connecting tube 1123 that abuts against the inner surface of the limiting portion 1115, and a receiving portion 1124 that is arranged on the connecting tube 1123 and bent downward along the radial direction of the connecting tube 1123. The connecting tube 1123 and the receiving portion 1124 are both cylindrical. The receiving portion 1124 divides the connecting tube 1123 into a connecting section 1125 connected to the limiting portion 1115 and a cutting portion 1126 that can abut against the movable tube 1122.

[0052] In this embodiment, the outer surface of the connecting section 1125 and the inner surface of the limiting portion 1115 are interference connected, and the top of the connecting section 1125 abuts against the inner wall of the cartridge housing 111. It can be understood that in other embodiments not shown, the connecting section 1125 can also be integrally formed with the limiting portion 1115, or the limiting portion 1115 can be omitted. When the limiting portion 1115 is omitted, the connecting section 1125 and the cartridge housing 111 are integrally formed, as long as the inner cavity of the connecting section 1125 and the vent hole 1112 are connected.

[0053] Please see again Figure 2-Figure 7 The movable tube 1122 is made of a silicone material. It is understandable that in other embodiments not shown, the movable tube 1122 can also be made of soft materials such as rubber and plastic. The movable tube 1122 includes an operating portion 1127 that is inserted into the connecting tube 1123 and protrudes out of the vent hole 1112, and a shielding portion 1128 that is arranged below the operating portion 1127 and corresponds to the inner cavity of the storage portion 1124. The axial length of the operating portion 1127 is greater than the axial length of the connecting tube 1123. The upper end of the shielding portion 1128 is provided with a groove 1129 corresponding to the cutting portion 1126 around the circumference of the operating portion 1127. A supporting section 1130 is provided on the outer surface of the shielding portion 1128 along the circumference of the shielding portion 1128. The user can pull the operating part 1127 upward to extend to the end outside the vent 1112, thereby driving the shielding part 1128 to move upward. When the bottom groove wall of the groove 1129 gradually abuts against the cutting part 1126, the abutting section 1130 gradually abuts against the inner surface of the storage part 1124. Since the upper end of the shielding part 1128 is provided with a groove 1129 corresponding to the cutting part 1126 around the periphery of the operating part 1127, the connection between the shielding part 1128 and the operating part 1127 is relatively fragile. When the bottom groove wall of the groove 1129 completely abuts against the cutting part 1126, the user can continue to pull the operating part 1127 upward to separate the operating part 1127 from the shielding part 1128. At this time, the abutting section 1130 abuts against the inner surface of the storage part 1124, so that the shielding part 1128 can be relatively fixed in the storage part 1124 under the action of the abutting force. In this embodiment, the groove 1129 is designed to be annular for ease of processing.

[0054] It is understandable that in other embodiments not shown, only the shielding portion 1128 is made of a soft material such as silicone, which can have good wrapping properties and better wrap the atomizing shell 1131 to better shield the liquid inlet hole 1134. The operating part 1127 and the shielding part 1128 are detachably connected, for example, the upper ends of the operating part 1127 and the shielding part 1128 are threadedly connected. Accordingly, when the liquid inlet hole 1134 needs to be exposed, the operating part 1127 is first slid upward. The groove 1129 is a discontinuous type, for example, one, two or three arc segments, and the cutting part 1126 adapted to the discontinuous groove 1129 is also set to be a discontinuous type. It is only necessary to ensure that when the shielding part 1128 moves upward under the drive of the operating part 1127 and abuts against the upper end of the storage part 1124, the cutting part 1126 can be inserted into the groove 1129. Since both are discontinuous, and the connecting pipe 1123 cannot be rotated or requires a greater force to rotate, the operating part 1127 can be separated from the shielding part 1128 by continuing to rotate. The operating part 1127 can be recycled repeatedly to reduce pollution and reduce costs.

[0055] It can be understood that in other embodiments not shown, the shielding portion 1128 and the operating portion 1127 can be detachably connected, and the detachable connection includes but is not limited to snap-on connection, plug-in connection, etc. In this case, the cutting groove 1129 can be omitted. When the cutting groove 1129 is omitted, the user pulls the operating portion 1127 upward, and the operating portion 1127 drives the shielding portion 1128 to move upward. The upper end of the shielding portion 1128 can directly abut against the cutting portion 1126. When the user continues to pull the operating portion 1127 upward, the operating portion 1127 can The shielding portion 1128 can be separated, or the groove 1129 and the cutting portion 1126 can be omitted. When the groove 1129 and the cutting portion 1126 are omitted, the user drives the shielding portion 1128 upward by pulling the operating portion 1127 upward, and the upper end of the shielding portion 1128 gradually abuts against the inner surface of the storage portion 1124. When the upper end of the shielding portion 1128 completely abuts against the inner surface of the storage portion 1124, the user can continue to pull the operating portion 1127 upward to separate the operating portion 1127 from the shielding portion 1128.

[0056] It can be understood that in other embodiments not shown, a groove is provided on the inner wall of the storage portion 1124 (not shown in the figure), and the user can pull the operating portion 1127 upward to drive the shielding portion 1128 to move upward, so that the abutting section 1130 can cooperate with the groove, so that the shielding portion 1128 is more firmly fixed in the storage portion 1124; or the abutting section 1130 can be omitted. When the abutting section 1130 is omitted, a protrusion is provided on the inner wall of the storage portion 1124, and the user can pull the operating portion 1127 upward to drive the shielding portion 1128 to move upward. The operating part 1127 drives the shielding part 1128 to move upward, so that the protrusion can resist against the outer surface of the shielding part 1128, so that the shielding part 1128 can be relatively fixed in the storage part 1124 under the action of the resisting force, or a card slot (not shown) is provided on the shielding part 1128, and the user drives the shielding part 1128 upward by pulling the operating part 1127 upward, so that the protrusion can cooperate with the card slot, so that the shielding part 1128 is more firmly fixed in the storage part 1124.

[0057] The atomization structure 113 includes an atomization shell 1131 disposed in the shielding portion 1128 and a heating element 1132 and a liquid absorption element 1133 installed in the atomization shell 1131. The liquid absorption element 1133 and the heating element 1132 cooperate with each other. For example, the liquid absorption element 1133 is wrapped around the outside of the heating element 1132, and the liquid absorption element 1133 is between the atomization shell 1131 and the heating element 1132.

[0058] The two ends of the atomizing shell 1131 are open, and a liquid inlet hole 1134 is opened on the side wall of the atomizing shell 1131. When the shielding part 1128 moves upward, the liquid inlet hole 1134 can be connected to the liquid storage chamber 1111. Specifically, the user pulls the operating part 1127 upward to make the shielding part 1128 irreversibly switch from the first state to the second state; in the first state, the shielding part 1128 is sleeved on the atomizing shell 1131 to shield the inlet of the atomizing shell 1131. Liquid hole, the liquid inlet hole 1134 is isolated from the liquid storage chamber 1111; in the second state, the shielding portion 1128 and the operating portion 1127 are separated, the shielding portion 1128 moves relative to the atomizing shell 1131 and exposes the liquid inlet hole 1134, and the liquid inlet hole 1134 is connected to the liquid storage chamber 1111. It can be understood that in this embodiment, after the shielding portion 1128 is irreversibly switched from the first state to the second state, the shielding portion 1128 can no longer switch from the second state to the first state.

[0059] An atomizing chamber (not marked) that can be connected to the vent hole 1112 is also formed in the atomizing shell 1131. For example, in this embodiment, the heating element 1132 is a columnar spiral heating wire, and the columnar spiral heating wire is the atomizing chamber. The smoke formed by the heating element 1132 heating the smoke liquid is mainly formed in the atomizing chamber.

[0060] The liquid absorbing member 1133 is made of a material that is easy to absorb liquid, such as cotton, cotton cloth or porous ceramics. The liquid absorbing member 1133 can gradually absorb the smoke liquid and gradually transfer the absorbed smoke liquid to the heating member 1132, so that the heating member 1132 heats the smoke liquid absorbed by the atomized liquid absorbing member 1133.

[0061] See also Figure 2 as well as Figure 6 The sealing structure 12 includes a cigarette cartridge plug 121 disposed in the cigarette cartridge housing 111 and sleeved on the atomizer housing 1131, a tail cap 122 connected to the cigarette cartridge plug 121, an airway plug 123 disposed in the tail cap 122, and an electrode contact 124 installed on the tail cap 122 for connecting to the battery device.

[0062] The cartridge plug 121 is made of silicone material. It is understandable that in other embodiments not shown, the cartridge plug 121 can also be made of materials with good sealing properties such as rubber. The cartridge plug 121 is provided with a placement hole 1211 corresponding to the atomizing housing 1131, and the cartridge plug 121 constitutes the bottom cavity wall of the liquid storage cavity 1111.

[0063] Please refer again Figure 2 The tail cap 122 includes a base 1221 disposed at the lower end of the cartridge housing 111 and a cap body 1222 disposed on the base 1221 and connected to the cartridge plug 121. The base 1221 is provided with a plurality of notches 1223 connected to the air inlet 1114, the cap body 1222 is located in the cartridge plug 121, and the cap body 1222 is provided with a plurality of guide holes (not shown) connected to the notches 1223.

[0064] The airway plug 123 is arranged in the cap body 1222, and a plurality of airway holes 1231 connecting the atomization chamber and the guide holes are opened on the airway plug 123. The outside air can enter the atomization chamber through the air inlet hole 1114, the notch 1223, the guide holes and the airway holes 1231 in sequence, so that the outside air can be mixed with the smoke in the atomization chamber.

[0065] In this embodiment, there are two electrode contacts 124, which are installed on the base 1221 at intervals. When the two electrode contacts 124 are respectively connected to the positive and negative electrodes on the battery device, the electronic cigarette is started and the circuit is turned on.

[0066] Installation process: install the atomizer shell 1131 in the shielding portion 1128, and sleeve the cigarette cartridge plug 121 on the lower end of the atomizer shell 1131, so that the liquid inlet hole 1134 is shielded by the shielding portion 1128; install the liquid absorbent 1133 and the heating element 1132 in the atomizer shell 1131, the airway plug 123 is arranged in the cap body 1222, the cap body 1222 is installed in the cigarette cartridge plug 121, and the base 1221 is installed at the lower end of the cigarette cartridge shell 111, and finally the operating part 1127 is passed through the connecting tube 1123 and extended to the outside of the vent 1112. At this time, the air inlet hole 1114, the notch 1223, the guide hole, the airway hole 1231 and the atomization chamber are all connected; install the battery device on the cigarette cartridge 10, so that the two electrode contacts 124 are respectively connected to the positive and negative poles on the battery device.

[0067] Usage process: When injecting liquid, the user can inject liquid into the liquid storage chamber 1111 through the liquid injection hole 1113. When the user finishes injecting liquid, the smoke liquid plug 1116 is installed in the liquid injection hole 1113. The smoke liquid plug 1116 can seal the liquid injection hole 1113 to prevent the smoke liquid in the liquid storage chamber 1111 from leaking.

[0068] When the user is not using the cigarette cartridge 10, the liquid inlet 1134 is shielded by the shielding portion 1128, and the liquid inlet 1134 is isolated from the liquid storage chamber 1111. When the user is using the cigarette cartridge 10, the user can pull the operating portion 1127 upward to extend to one end outside the vent 1112, thereby driving the shielding portion 1128 to move upward. When the bottom groove wall of the groove 1129 gradually abuts against the cutting portion 1126, the abutting section 1130 gradually abuts against the inner surface of the storage portion 1124. Since the upper end of the shielding portion 1128 is provided with a groove 1129 corresponding to the cutting portion 1126 around the periphery of the operating portion 1127, the connection between the shielding portion 1128 and the operating portion 1127 is relatively fragile. When the bottom groove wall of the groove 1129 is completely When abutting against the cutting portion 1126, the user can continue to pull the operating portion 1127 upwards so that the operating portion 1127 can be separated from the shielding portion 1128. At this time, the abutting section 1130 completely abuts against the inner surface of the storage portion 1124, so that the shielding portion 1128 can be relatively fixed in the storage portion 1124 under the action of the abutting force. At this time, the shielding portion 1128 no longer covers or partially covers the liquid inlet hole 1134. The liquid inlet hole 1134 is connected to the liquid storage chamber 1111. The smoke liquid in the liquid storage chamber 1111 can enter the atomizer shell 1131 through the liquid inlet hole 1134, and the smoke liquid is gradually absorbed by the liquid absorption component 1133 in the atomizer shell 1131, and the absorbed smoke liquid is gradually conducted to the heating component 1132.

[0069] When inhaling, the electronic cigarette is started, the positive and negative electrodes on the battery device are connected to the two electrode contact members 124 respectively, the circuit is turned on, the heating member 1132 starts to heat the smoke liquid absorbed by the atomizing liquid absorbing member 1133, and the outside air can enter the atomizing chamber through the air inlet hole 1114, the notch 1223, the guide hole and the airway hole 1231 in sequence, so that the outside air can be mixed with the smoke in the atomizing chamber, and the user can inhale the smoke through the air vent 1112.

[0070] Embodiment 2

[0071] Please also see Figure 8-Figure 11 The main difference between the cigarette cartridge 10 provided in the second embodiment and the cigarette cartridge 10 in the first embodiment is that the cigarette cartridge plug 121 and the lower end of the shielding portion 1128 are integrally formed, and a circular cutout 1212 is provided at the connection between the cigarette cartridge plug 121 and the shielding portion 1128 along the circumference of the shielding portion 1128. When the user pulls the operating portion 1127 upward to the end outside the vent 1112, the operating portion 1127 drives the shielding portion 1128 to move upward, and the shielding portion 1128 drives the cigarette cartridge plug 121 to move upward, and the storage The smoke liquid in the liquid chamber 1111 is gradually introduced into the atomizing housing 1131 through the liquid inlet hole 1134 by the pressure of the smoke cartridge plug 121 moving upward. After the shielding portion 1128 drives the smoke cartridge plug 121 to move upward for a certain displacement, the connection between the smoke cartridge plug 121 and the shielding portion 1128 is relatively fragile because the connection between the smoke cartridge plug 121 and the shielding portion 1128 is provided with an annular cutout 1212. The smoke cartridge plug 121 is gradually separated from the shielding portion 1128. When the bottom groove wall of the cutout 1129 is gradually connected to the connection, the smoke cartridge plug 121 is gradually separated from the shielding portion 1128. When the lower end of the connecting pipe 1123 abuts, the abutting section 1130 gradually abuts against the inner surface of the receiving portion 1124. Since the upper end of the shielding portion 1128 is provided with a groove 1129 corresponding to the cutting portion 1126 around the periphery of the operating portion 1127, the connection between the shielding portion 1128 and the operating portion 1127 is relatively fragile. When the bottom groove wall of the groove 1129 completely abuts against the connecting pipe 1123, the user can continue to pull the operating portion 1127 upwards so that the operating portion 1127 can be separated from the shielding portion 1128. The shielding portion 1128 is separated from the atomizing shell 1131. At this time, the abutting section 1130 completely abuts against the inner surface of the receiving portion 1124. The shielding portion 1128 can be relatively fixed in the receiving portion 1124 under the action of the abutting force. At this time, the liquid inlet hole 1134 is connected with the liquid storage chamber 1111. The smoke liquid in the liquid storage chamber 1111 can enter the atomizing shell 1131 through the liquid inlet hole 1134. The smoke liquid is gradually absorbed by the liquid absorbing member 1133 in the atomizing shell 1131, and the absorbed smoke liquid is gradually conducted to the heating member 1132.

[0072] It can be understood that in other embodiments not shown, the storage portion 1124 can be omitted. When the storage portion 1124 is omitted, the cutting portion 30 can be set on the inner wall of the groove 1129. When the user pulls the operating portion 1127 upward to extend to the end outside the vent 1112, the operating portion 1127 drives the shielding portion 1128 to move upward, and the bottom groove wall of the groove 1129 gradually abuts against the lower end of the cutting portion 1126, and the abutting section 1130 gradually abuts against the outer surface of the cutting portion 1126. When the bottom groove wall of the groove 1129 completely abuts against the cutting portion 1126, the user can continue to pull the operating portion 1127 upward to separate the operating portion 1127 from the shielding portion 1128. At this time, the abutting section 1130 completely abuts against the outer surface of the cutting portion 1126, and the shielding portion 1128 can be relatively fixed in the storage portion 1124 under the action of the abutting force.

[0073] It can be understood that in other embodiments not shown, the connecting section of the cigarette cartridge plug 121 and the shielding portion 1128 is provided with a slide rail (not shown in the figure), and a slide groove corresponding to the slide rail is opened on the inner wall of the atomizer shell 1131 (not shown in the figure). When the cigarette cartridge 10 is not in use, the slide rail is located in the slide groove. With the cooperation of the slide rail and the slide groove, the cigarette cartridge plug 121 and the shielding portion 1128 remain relatively fixed. When the user pulls the operating portion 1127 upward to extend to the end outside the vent 1112, the slide rail gradually disengages from the slide groove, so that the cigarette cartridge plug 121 and the shielding portion 1128 are gradually separated. It can be understood that in other embodiments not shown, as long as the user can pull the operating portion 1127 upward to extend to the end outside the vent 1112, the operating portion 1127 drives the shielding portion 1128 to move upward, and the shielding portion 1128 drives the cigarette cartridge plug 121 to move upward for a certain displacement, the cigarette cartridge plug 121 can be gradually separated from the shielding portion 1128.

[0074] In the electronic cigarette of the present invention, the movable structure 112 includes an isolation guide tube 1121 disposed in the cartridge housing 111 and an movable tube 1122 at least partially disposed in the isolation guide tube 1121, the movable tube 1122 includes an operating portion 1127 and a shielding portion 1128, the operating portion 1127 is disposed in the isolation guide tube 1121 and one end of the operating portion 1127 extends to the vent 1112, the atomizing structure 113 is provided with a liquid inlet hole 1134 that can communicate with the liquid storage chamber 1111, and the shielding portion 1128 The shielding part 1128 is movably mounted on the atomizing structure 113 to cover or expose the liquid inlet hole 1134, so that the liquid inlet hole 1134 is isolated from or connected to the liquid storage chamber 1111. When the user does not use the electronic cigarette, the shielding part 1128 is mounted on the atomizing shell 1131 to cover the liquid inlet hole 1134. When the user uses the electronic cigarette, the shielding part 1128 is separated from the operating part 1127, and the shielding part 1128 moves relative to the atomizing shell 1131 to expose the liquid inlet hole 1134, and the liquid inlet hole 1134 is connected to the liquid storage chamber 1111. The electronic cigarette of the present invention can separate the oil cotton when the user does not use the electronic cigarette, so as to facilitate the storage of the smoke liquid.

[0075] The above embodiments only express the implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
