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. Summary of the invention

[0004] Based on this, it is necessary to provide a cigarette cartridge and an electronic cigarette using the cigarette cartridge to address one of the above problems.

[0006] In the first state, the shielding portion is sleeved on the atomizing structure to shield the liquid inlet hole of the atomizing structure, the liquid inlet hole is isolated from the liquid storage chamber, the sealing member blocks the air inlet hole of the atomizing chamber, and the movable structure blocks the auxiliary air inlet hole of the atomizing chamber;

[0007] In the second state, the operating part is operated to move in a direction away from the liquid inlet hole, driving the shielding part to move and expose the liquid inlet hole, and the liquid inlet hole is connected with the liquid storage chamber. During the movement of the operating part, part of the inner wall of the shielding part forms an auxiliary atomization chamber connected with the atomization chamber through the auxiliary air inlet hole. The pressure of the atomization chamber decreases due to the increase in volume, so that the flow rate of the smoke liquid in the liquid storage chamber through the liquid inlet hole is accelerated due to the pressure difference.

[0008] Furthermore, in the second state, the shielding portion is continuously operated to separate the operating portion from the shielding portion, and the sealing member is removed to put the cigarette cartridge into a ready-to-use state.

[0009] Furthermore, the atomization structure includes an atomization shell and a heating element and a liquid absorption element arranged in the atomization shell. The liquid inlet hole and the auxiliary air inlet hole are opened on the atomization shell. The smoke liquid is absorbed by the liquid absorption element from the liquid inlet hole and supplied to the heating element.

[0010] Furthermore, the inner cavity of the isolation guide tube is communicated with the vent hole, and the side of the operating part abuts against the inner cavity wall of the isolation guide tube.

[0011] Furthermore, the cigarette cartridge also includes a tail cap structure, which includes a cigarette cartridge plug connected to one end of the cigarette cartridge shell and used to seal one end of the liquid storage chamber.

[0012] Furthermore, the tail cap structure also includes a tail cap partially accommodated in the cigarette cartridge plug and two electrode contact members installed on the tail cap, and the tail cap is provided with an air inlet hole connecting the outside and the placement hole.

[0013] Furthermore, a blocking portion is protruding from the sealing member, and the blocking portion extends into the air inlet hole to block the air inlet hole.

[0014] Furthermore, the cigarette cartridge also includes an upper cover structure, which includes a cigarette cartridge cover arranged on the cigarette cartridge housing and a cigarette holder sleeved on the cigarette cartridge cover.

[0015] Furthermore, a liquid injection hole connected to the liquid storage chamber is opened at the upper end of the cigarette cartridge shell, a sealing column is protruded on the cigarette cartridge cover, and an end of the sealing column away from the cigarette cartridge cover extends into the liquid injection hole to seal the liquid injection hole.

[0016] An electronic cigarette comprises a battery device and a cigarette cartridge electrically connected to the battery device, wherein the cigarette cartridge is any of the cigarette cartridges described above.

[0017] In the electronic cigarette of the present invention, since the operating part is arranged in the isolation guide tube, the atomizing structure is provided with an atomizing chamber and a liquid inlet hole that can be connected to the liquid storage chamber, a sealing member is provided at one end of the atomizing structure, and an air extraction hole that keeps the atomizing chamber connected with the outside is provided on the sealing member, and the operating part can be operated to switch the shielding part from the first state to the second state; in the first state, the shielding part is sleeved on the atomizing structure to shield the liquid inlet hole of the atomizing structure, the liquid inlet hole is isolated from the liquid storage chamber, the sealing member blocks the air inlet hole of the atomizing chamber, and the movable structure blocks the auxiliary smoke outlet hole of the atomizing chamber; in the second state, the operating part is operated to move in a direction away from the liquid inlet hole, driving the shielding part to move and expose the liquid inlet hole, and the liquid inlet hole is connected with the liquid storage chamber. During the movement of the operating part, part of the inner wall of the shielding part forms an auxiliary atomizing chamber that is connected to the atomizing chamber through the auxiliary smoke outlet hole, and the pressure of the atomizing chamber decreases due to the increase in volume, so that the smoke liquid in the liquid storage chamber accelerates the flow rate through the liquid inlet hole due to the pressure difference. The electronic cigarette of the present invention can separate the oil and cotton when the user is not using the electronic cigarette, thereby facilitating the storage of the smoke liquid; when the user is using the electronic cigarette, the speed at which the smoke liquid in the liquid storage chamber passes through the liquid inlet hole is accelerated.

[0030] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0031] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0032] 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.

[0033] Please see Figure 1-Figure 3 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, and 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.

[0034] The cigarette cartridge 10 includes a cigarette cartridge body 11 , a tail cap structure 12 installed at one end of the cigarette cartridge body 11 , and an upper cover structure 13 installed at the other end of the cigarette cartridge body 11 relative to the tail cap structure 12 .

[0035] See also Figure 4 and Figure 5 The cigarette cartridge body 11 includes a cigarette cartridge housing 111 and a movable structure 112 and an atomization structure 113 accommodated in the cigarette cartridge housing 111 .

[0036] In one embodiment, the cartridge shell 111 is roughly cylindrical with an open lower end, and the inner cavity of the cartridge shell 111 forms a liquid storage chamber 1111. The upper end surface of the cartridge shell 111 is respectively provided with a liquid injection hole 1113 connected to the liquid storage chamber 1111 and a ventilation hole 1112 for one end of the movable structure 112 to pass through. The inner wall of the cartridge shell 111 near the ventilation hole 1112 protrudes downward along the axial direction of the cartridge shell 111 to form a limiting portion 1115 that can abut against the movable structure 112. The upper end of the side wall of the cartridge shell 111 is relatively provided with two snap-in protrusions 1116 for connecting to the upper cover structure 13, and the lower end of the side wall of the cartridge shell 111 is relatively provided with at least one snap-in hole 1117 for connecting to the tail cap structure 12.

[0037] The movable structure 112 includes an isolation guide tube 1121 at least partially disposed in the limiting 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.

[0038] Please also see Figure 4 , 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 end 1123 that abuts against the inner surface of the limiting portion 1115 and an end of the connecting end 1123 away from the limiting portion 1115 that extends downward along the axial direction of the connecting end 1123 to the storage chamber 1111. Receiving end 1124, in this embodiment, the outer surface of the connecting end 1123 and the inner surface of the limiting portion 1115 are connected by interference fit, and the receiving end 1124 and the connecting end 1123 are integrally formed, and the connecting end 1123 and the receiving end 1124 are both cylindrical. It can be understood that in other embodiments not shown, the connecting end 1123 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 end 1123 and the cigarette cartridge housing 111 are integrally formed, as long as the inner cavity of the connecting end 1123 and the vent hole 1112 are connected.

[0039] Please see again Figure 2-Figure 10 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 connection end 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 receiving end 1124. The outer surface of the operating portion 1127 can be connected to the inner surface of the limiting portion 1115 by interference fit. The upper end of the shielding portion 1128 is provided with a groove 1129 corresponding to the receiving end 1124 around the periphery of the operating portion 1127. A supporting section 1130 that can support the outer surface of the receiving end 1124 is provided on the groove wall of the groove 1129 along the circumference of the groove 1129. The user can pull the operating portion 1127 upward to extend to one end outside the vent hole 1112, thereby driving the shielding portion 1128 to move upward. When the bottom groove wall of the groove 1129 gradually abuts against the lower end of the storage end 1124, the abutting section 1130 gradually abuts against the outer surface of the storage end 1124. Since the upper end of the shielding portion 1128 is provided with a groove 1129 corresponding to the storage end 1124 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 lower end of the storage end 1124, the user can continue to pull upward. By pulling the operating part 1127, the operating part 1127 can be separated from the shielding part 1128. On the one hand, the outer surface of the operating part 1127 pulled upward by the user can always be connected with the inner surface of the limiting part 1115 by interference fit during the pulling process, until the operating part 1127 and the shielding part 1128 are separated, and the outside air can enter the liquid storage chamber 1111 through the vent hole 1112; on the other hand, when the operating part 1127 is completely separated from the shielding part 1128, the abutting section 1130 completely abuts against the outer surface of the receiving end 1124, so that the shielding part 1128 can be fixed on the receiving end 1124 under the action of the abutting force. In this embodiment, the groove 1129 is designed to be annular for easy processing.

[0040] 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 atomization shell 1131 to better shield the liquid inlet hole 1134. The operating portion 1127 and the shielding portion 1128 are detachably connected, and the detachable connection includes but is not limited to snap-in, plug-in, etc. For example, the upper ends of the operating portion 1127 and the shielding portion 1128 are threadedly connected. Accordingly, when the liquid inlet hole 1134 needs to be exposed, the operating portion 1127 is first slid upward. The groove 1129 is non-continuous, for example, it is one, two or three arc segments, and the storage end 1124 adapted to the non-continuous groove 1129 is also set to be non-continuous. It is only necessary to ensure that when the shielding portion 1128 moves upward driven by the operating portion 1127 and abuts against the lower end of the storage end 1124, the lower end of the storage end 1124 can be inserted into the groove 1129. Since both are non-continuous and the connecting end 1123 cannot be rotated, the operating portion 1127 can be separated from the shielding portion 1128 by continuing to rotate the operating portion 1127. The operating part 1127 can be recycled repeatedly to reduce pollution and lower costs.

[0041] It can be understood that in other embodiments not shown, a groove (not shown) that can correspond to the abutting section 1130 is opened on the outer wall of the storage end 1124, and the user pulls 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 can be more firmly fixed on the storage end 1124; or the abutting section 1130 can be omitted. When the abutting section 1130 is omitted, a protrusion is provided on the outer wall of the storage end 1124, The user drives the shielding portion 1128 upward by pulling the operating portion 1127 upward, and the protrusion can resist against the wall of the groove 1129, so that the shielding portion 1128 can be fixed on the storage end 1124 under the action of the resisting force, or a card slot is further provided on the wall of the groove 1129 (not shown in the figure), and the user drives the shielding portion 1128 upward by pulling the operating portion 1127 upward, so that the protrusion can cooperate with the card slot, so that the shielding portion 1128 is more firmly fixed in the storage end 1124.

[0042] Please see again Figure 4 , Figure 6 as well as Figure 8 The atomization structure 113 includes an atomization shell 1131 disposed in the shielding portion 1128 and a heating element 1132 and a liquid absorbing element 1133 installed in the atomization shell 1131. The liquid absorbing element 1133 and the heating element 1132 cooperate with each other. For example, the liquid absorbing element 1133 is wrapped around the outside of the heating element 1132, and the liquid absorbing element 1133 is between the atomization shell 1131 and the heating element 1132.

[0043] Both ends of the atomizer shell 1131 are open, and a liquid inlet hole 1134 that can communicate with the liquid storage chamber 1111 is formed on the side wall of the atomizer shell 1131. The upper end opening of the atomizer shell 1131 forms an auxiliary smoke outlet hole 1135 that is connected to the liquid inlet hole 1134, and an auxiliary atomization chamber 1136 that is connected to the auxiliary smoke outlet hole 1135 is formed between the inner surface of the shielding portion 1128 and the upper end surface of the atomizer shell 1131.

[0044] In this embodiment, after the shielding portion 1128 moves upward, the liquid inlet hole 1134 gradually communicates with the liquid storage chamber 1111. As the volume of the auxiliary atomization chamber 1136 increases, the air in the atomization chamber gradually enters the auxiliary atomization chamber 1136, and the gas pressure in the atomization chamber decreases. The gas pressure in the atomization chamber is less than the gas pressure in the liquid storage chamber 1111. In order to keep the internal and external gas pressures of the atomization housing 1131 in dynamic balance, the air in the liquid storage chamber 1111 passes through the liquid inlet hole 1134. 134 gradually enters the atomization chamber. When the air in the liquid storage chamber 1111 enters the atomization chamber, it drives the smoke liquid in the liquid storage chamber 1111 to enter the atomization chamber, so that the smoke liquid in the liquid storage chamber 1111 can enter the liquid inlet hole 1134 under the action of the pressure difference, which speeds up the flow rate of the smoke liquid through the liquid inlet hole 1134 and speeds up the process of the smoke liquid infiltrating the liquid absorbing member 1133, so that the liquid absorbing member 1133 can be completely infiltrated by the smoke liquid in a shorter time, saving the user from waiting for the liquid absorbing member 1133 absorbs the smoke liquid, thereby improving the user's experience. Specifically, the operation part 1127 can be operated to switch the shielding part 1128 from the first state to the second state; in the first state, the shielding part 1128 is sleeved on the atomization structure 113 to shield the liquid inlet hole 1134 of the atomization structure 113, the liquid inlet hole 1134 is isolated from the liquid storage chamber 1111, and the movable structure 112 blocks the auxiliary smoke outlet hole 1135 of the atomization chamber; in the second state, the operation part 1127 is operated The operating part 1127 moves in a direction away from the liquid inlet hole 1134, driving the shielding part 1128 to move and expose the liquid inlet hole 1134. The liquid inlet hole 1134 is connected with the liquid storage chamber 1111. During the movement of the operating part 1127, part of the inner wall of the shielding part 1128 forms an auxiliary atomization chamber 1136 connected with the atomization chamber through the auxiliary smoke outlet hole 1135. The pressure of the atomization chamber decreases due to the increase in volume, so that the smoke liquid in the liquid storage chamber 1111 is accelerated to flow through the liquid inlet hole 1134 due to the pressure difference.

[0045] Please also see Figure 4 An atomizing chamber (not marked) that can be connected to the auxiliary atomizing chamber 1136 is also formed in the atomizing shell 1131. For example, in this embodiment, the heating element 1132 is a columnar spiral heating wire, then the columnar spiral heating wire is the atomizing chamber, and the smoke formed by the heating element 1132 heating the smoke liquid is mainly formed in the atomizing chamber.

[0046] 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.

[0047] Please see again Figure 4 , Figure 5 as well as Figure 6 The tail cap 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 partially received in the cigarette cartridge plug 121 and connected to the lower end of the cigarette cartridge housing 111, two electrode contacts 124 installed on the tail cap 122 for connecting to the battery device, and a sealing member 1137 installed at the lower end of the tail cap 122.

[0048] The cigarette cartridge plug 121 is made of silicone material. It can be understood that in other embodiments not shown, the cigarette cartridge plug 121 can also be made of materials with good sealing properties such as rubber. A placement hole 1211 corresponding to the atomization shell 1131 is provided on the cigarette cartridge plug 121. The upper end surface of the cigarette cartridge plug 121 constitutes the bottom cavity wall of the liquid storage chamber 1111. On the outer surface of the cigarette cartridge plug 121, there is at least one protrusion 1212 for abutting against the inner surface of the cigarette cartridge shell 111 along the circumference of the cigarette cartridge plug 121. The cigarette cartridge plug 121 is tensioned with the protrusion 1212 and the inner surface of the cigarette cartridge shell 111. On the one hand, the sealing member 121 can be more firmly connected to the cigarette cartridge shell 111, and on the other hand, it can prevent the smoke liquid in the liquid storage chamber 1111 from leaking to the outside through the gap between the cigarette cartridge plug 121 and the cigarette cartridge shell 111.

[0049] Please refer again Figure 4 The tail cap 122 includes a base 1221 connected to the lower end of the cigarette cartridge housing 111 and a cap body 1222 disposed on the base 1221 and connected to the cigarette cartridge plug 121 .

[0050] The lower end of the base 1321 is respectively provided with an air inlet 1114 connected to the outside and two electrode holes 1224 for installing two electrode contacts 124. The two electrode holes 1224 are spaced apart on both sides of the air inlet 1114. In this embodiment, the base 1321 and the cartridge housing 111 are two independent parts. The base 1321 and the cartridge housing 111 are connected by detachable connection methods such as snap-on and plug-in. Specifically, the side of the base 1221 is also provided with a snap-on block 1225 corresponding to the snap-on hole 1117. The number of the snap-on blocks 1225 is equal to the number of the snap-on holes 1117. It can be understood that in other embodiments not shown, the base 1321 and the cartridge housing 111 can also be integrally formed. It can be understood that in other embodiments not shown, the cartridge plug 121 can be omitted. When the cartridge plug 121 is omitted, the base 1221 is directly connected to the lower end of the cartridge housing 111.

[0051] The cap body 1222 is located in the cigarette cartridge plug 121, and the cap body 1222 protrudes upward along the axial direction of the cap body 1222 to form a barrel body 1226 with openings at both ends corresponding to the placement hole 1211. The lower end opening of the barrel body 1226 passes through the cap body 1222 and is connected to the air inlet hole 1114, so that the inner cavity of the barrel body 1226 is connected to the air inlet hole 1114 and the atomization chamber, and the outside air can enter the atomization chamber through the air inlet hole 1114 and the inner cavity of the barrel body 1226 in turn, so that the outside air can be mixed with the smoke in the atomization chamber.

[0052] The two electrode contacts 124 are respectively installed in the two electrode holes 1224 and connected to the lower end of the heating element 1132. 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.

[0053] Please refer again Figure 2-Figure 4 The seal 1137 is provided with at least one suction hole 1138 connecting the outside and the atomization chamber. The diameter of the suction hole 1138 is smaller than the diameter of the air inlet 1114. The upper end of the seal 1137 protrudes upward along the axial direction of the seal 1137 to form a blocking portion 1139. The blocking portion 1139 is used to block the air inlet 1114. In the first state, the seal blocks the air inlet 1114. In the second state, when the liquid absorbing member 1133 is completely soaked by the smoke liquid in a short time, the user can remove the seal 1137 to put the cigarette cartridge 10 into the ready-to-use state. In this embodiment, when the movable structure 112 and the seal 1137 exist at the same time, the oil cotton is separated and the smoke liquid is in the storage state. In the ready-to-use state, the liquid absorbing member 1133 is completely soaked by the smoke liquid. The user can remove the seal 1137 and electrically connect the cigarette cartridge 10 to the battery device for use by the user.

[0054] See also Figure 2 and Figure 3 The upper cover structure 13 includes a cartridge cover 131 disposed at the upper end of the cartridge housing 111 for sealing the injection hole 1113 and a mouthpiece 132 installed at the upper end of the cartridge housing 111 .

[0055] The cigarette cartridge cover 131 is made of a soft material with good sealing performance, such as silicone and rubber. A connecting hole 1311 corresponding to the vent hole 1112 is provided on the cigarette cartridge cover 131 for the end of the operating part 1127 away from the shielding part 1128 to pass through. The lower end surface of the cigarette cartridge cover 131 protrudes downward along the axial direction of the cigarette cartridge cover 131 to form a sealing column 1312 corresponding to the injection hole 1113 and capable of sealing the injection hole 1113 after injection. When the user has finished filling the liquid storage chamber 1111 with smoke liquid through the injection hole 1113, the sealing column 1312 is installed in the injection hole 1113. The sealing column 1312 can seal the injection hole 1113 to prevent the smoke liquid in the liquid storage chamber 1111 from leaking from the injection hole 1113. In this embodiment, there are two injection holes 1113, which are relatively opened on the upper end surface of the cartridge housing 111. Correspondingly, there are two sealing columns 1312, which are respectively corresponding to the two injection holes 1113 and are arranged on the lower end surface of the cartridge cover 131. Understandably, in other embodiments not shown, the injection hole 1113 can be omitted. When the injection hole 1113 is omitted, the user can pierce the upper end of the cartridge cover 131 with a syringe corresponding to the sealing column 1312, so that the two ends of the sealing column 1312 are connected, and the inner cavity of the sealing column 1312 after the penetration is connected is connected to the liquid storage cavity 1111. The user can add smoke liquid to the upper end of the sealing column 1312, and the smoke liquid flows to the liquid storage cavity 1111 through the inner cavity of the sealing column 1312. Alternatively, the injection hole 1113 and the cartridge cover 131 are omitted. When the injection hole 1113 and the cartridge cover 131 are omitted, the cartridge shell 111 adopts a pre-packaged manner to inject the smoke liquid from the lower end of the cartridge shell 111 into the cartridge 10. When the smoke liquid is consumed, the cartridge 10 is discarded as a whole, and it is a non-refillable cartridge 10.

[0056] In this embodiment, the cigarette holder 132 is provided with a smoke outlet 1321 corresponding to the connection hole 1311 for the end of the operating portion 1127 away from the shielding portion 1128 to pass through. In this embodiment, the cigarette holder 132 and the cigarette cartridge housing 111 are two independent parts, and the cigarette holder 132 and the cigarette cartridge housing 111 are connected by a detachable connection method such as snap-on or plug-in. Specifically, two snap interfaces 1322 are provided on the side of the cigarette holder 132 corresponding to the two snap-on protrusions 1116. It can be understood that in other embodiments not shown, the cigarette holder 132 and the cigarette cartridge housing 111 can also be integrally formed.

[0057] Installation process: one end of the operating part 1127 is successively passed through the inner cavity of the connecting end 1123, the vent hole 1112 and the connecting hole 1311, and then extended to the outside of the smoke outlet 1321; the atomizing shell 1131 is installed in the shielding part 1128, and the cigarette cartridge plug 121 is sleeved on the lower end of the atomizing shell 1131, and the liquid inlet 1134 is shielded by the shielding part 1128; the liquid absorbing part 1133 and the heating part 1132 are installed in the atomizing shell 1131, 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; the sealing part 1137 is installed at the lower end of the tail cap 122, the air extraction hole 1138 is connected to the outside and the atomizing cavity, the blocking part 1139 is installed in the air inlet hole 1114, and the air inlet hole 1114 is sealed by the blocking part 1139.

[0058] The battery device is mounted on the cigarette cartridge 10 so that the two electrode contacts 124 connected to the lower end of the heating element 1132 are connected to the positive and negative electrodes on the battery device respectively.

[0059] Usage process: Please refer to Figure 6 When the user does not use the cigarette cartridge 10, the liquid inlet hole 1134 is shielded by the shielding portion 1128, the liquid inlet hole 1134 and the liquid storage chamber 1111 are isolated, the volume in the auxiliary atomization chamber 1136 is minimized, and the smoke outlet hole 1321 is shielded by the operating portion 1127. External air cannot enter the atomization chamber through the smoke outlet hole 1321. Since the blocking portion 1139 is installed in the air inlet hole 1114, the air extraction hole 1138 connects the outside world and the atomization chamber, and the air inlet hole 1114 is sealed by the blocking portion 1139.

[0060] Please see Figure 8 and Fig.10When the user uses the cigarette cartridge 10, the user pulls the operating portion 1127 upward to extend to one end outside the vent hole 1112, thereby driving the shielding portion 1128 to move upward. The outer surface of the operating portion 1127 pulled upward by the user can always be connected with the inner surface of the limiting portion 1115 by interference fit during the pulling process. Therefore, the operating portion 1127 can block the smoke outlet 1321, and external gas cannot enter the atomization chamber through the smoke outlet 1321; further, when the side wall of the shielding portion 1128 moves upward, when the shielding portion 1128 gradually no longer covers or partially covers the liquid inlet hole 1134, the liquid inlet hole 1134 gradually communicates with the liquid storage chamber 1111 , the smoke liquid in the liquid storage chamber 1111 can flow into the gradually exposed liquid inlet hole 1134 and be absorbed by the liquid absorption member 1133. At this time, the atomization chamber can communicate with the liquid inlet hole 1134 and the air inlet hole 1114. Furthermore, since the auxiliary smoke outlet hole 1135 is connected to the atomization chamber, while the shielding portion 1128 gradually moves upward, the volume of the auxiliary atomization chamber 1136 gradually increases. Since the auxiliary atomization chamber 1136 is connected to the atomization chamber through the auxiliary smoke outlet hole 1135, while the volume of the auxiliary atomization chamber 1136 gradually increases, the air in the atomization chamber gradually flows into the auxiliary atomization chamber 1136, so that the air in the atomization chamber gradually decreases, and the volume of the atomization chamber 1136 in the atomization housing 1131 is gradually reduced. The air pressure is lower than the air pressure outside the atomizing housing 1131 and forms a pressure difference. Since the air inlet 1114 is sealed by the blocking portion 1139, the air extraction hole 1138 is connected to the outside and the atomizing chamber. When the user pulls up the end of the operating portion 1127 extending outside the air vent 1112, in order to keep the air pressure inside the atomizing housing 1131 and the air pressure outside the atomizing housing 1131 in dynamic balance, the air in the liquid storage chamber 1111 gradually enters the atomizing chamber through the liquid inlet hole 1134. When the air in the liquid storage chamber 1111 gradually enters the atomizing chamber, the smoke liquid in the liquid storage chamber 1111 is driven to enter the atomizing chamber. In addition, in order to keep the atomizing housing 1131 in dynamic balance, the air in the liquid storage chamber 1111 gradually enters the atomizing chamber. The air pressure inside and outside achieves a large pressure difference at the moment the user pulls the operating part 1127 upwards. In addition, in order to ensure that the atomization chamber is connected to the outside air when the user pulls one end of the operating part 1127 upwards, and to prevent the operating part 1127 from getting stuck when being pulled upwards, when the user pulls the operating part 1127 upwards, the air pressure in the atomization chamber is less than the air pressure of the outside air and a pressure difference is formed. The outside air slowly enters the atomization chamber through the suction hole 1138 with a smaller aperture, so that the air pressure inside and outside the atomization shell 1131 still maintains a large pressure difference, further accelerating the speed at which the smoke liquid in the liquid storage chamber 1111 enters the atomization chamber through the liquid inlet hole 1134.Furthermore, the external air flowing through the atomization chamber can promote the absorption of smoke liquid by the liquid absorption component 1133, speeding up the process of smoke liquid infiltrating the liquid absorption component 1133, so that the liquid absorption component 1133 can be completely infiltrated by the smoke liquid in a shorter time, saving the time for the user to wait for the liquid absorption component 1133 to absorb the smoke liquid, and improving the user's usage experience. If the time for the smoke liquid to infiltrate the liquid absorption component 1133 is too long, the user needs to wait for a long time before using it. If the time for the smoke liquid to infiltrate the liquid absorption component 1133 is too short, the smoke liquid cannot be completely infiltrated by the liquid absorption component 1133 in a shorter time. When the user uses it, the heating component 1132 is prone to dry burning, affecting the customer's usage experience. When the bottom groove wall of the groove 1129 gradually abuts against the lower end of the storage end 1124, the abutting section 1130 gradually abuts against the outer surface of the storage end 1124. Since the upper end of the shielding portion 1128 is provided with a groove 1129 corresponding to the storage end 1124 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 lower end of the storage end 1124, the user can continue to pull the operating portion 1127 upwards, and the operating portion 1127 can be separated from the shielding portion 1128. At this time, on the one hand, the operating part 1127 and the shielding part 1128 can be separated from the smoke outlet 1321 after separation, and the outside air can enter the liquid storage chamber 1111 through the smoke outlet 1321; on the other hand, when the operating part 1127 is completely separated from the shielding part 1128, the supporting section 1130 completely supports the outer surface of the storage end 1124, so that the shielding part 1128 can be fixed on the storage end 1124 under the action of the supporting force. At this time, the volume of the air in the auxiliary atomization chamber 1136 is the largest, and the shielding part 1128 no longer covers or partially covers the liquid inlet hole 1134. The liquid inlet hole 1134 is connected with the liquid storage chamber 1111, and the smoke liquid in the liquid storage chamber 1111 can enter the atomization shell 1131 through the liquid inlet hole 1134, and the smoke liquid is gradually absorbed by the liquid absorption part 1133 in the atomization shell 1131, and the absorbed smoke liquid is gradually conducted to the heating element 1132.

[0061] When inhaling, remove the sealing member 1137 to expose the larger air inlet hole 1114. Since the larger air inlet hole 1114 is exposed, a large amount of outside air can enter the atomization chamber through the air inlet hole 1114. At this time, the positive and negative electrodes on the battery device are respectively connected to the two electrode contacts 124, the circuit is turned on, the electronic cigarette is started, and the heating member 1132 starts to heat the smoke liquid absorbed by the atomizing liquid absorbing member 1133. The outside air can enter the atomization chamber through the air inlet hole 1114 and the inner cavity of the barrel 1226 in turn, and the outside air can be mixed with the smoke in the atomization chamber, and the user can inhale the smoke through the smoke outlet 1321.

[0062] In the electronic cigarette of the present invention, since the operating part 1127 is arranged in the isolation guide tube 1121, the atomizing structure 113 is provided with an atomizing chamber and a liquid inlet hole 1134 that can communicate with the liquid storage chamber 1111, and a sealing member 1137 is provided at one end of the atomizing structure 113, and an air extraction hole 1138 that keeps the atomizing chamber connected with the outside is provided on the sealing member 1137, and the operating part 1127 can be operated to switch the shielding part 1128 from the first state to the second state; in the first state, the shielding part 1128 is sleeved on the atomizing structure 113 to shield the liquid inlet hole 1134 of the atomizing structure 113, and the liquid inlet hole 1134 is isolated from the liquid storage chamber 1111, and the sealing member 1137 is provided at one end of the atomizing structure 113. 37 blocks the air inlet 1114 of the atomizing chamber, and the movable structure 112 blocks the auxiliary smoke outlet 1135 of the atomizing chamber; in the second state, the operating part 1127 is operated to move in the direction away from the liquid inlet 1134, driving the shielding part 1128 to move and expose the liquid inlet 1134, and the liquid inlet 1134 is connected with the liquid storage chamber 1111. During the movement of the operating part 1127, part of the inner wall of the shielding part 1128 forms an auxiliary atomizing chamber 1136 connected with the atomizing chamber through the auxiliary smoke outlet 1135. The pressure of the atomizing chamber decreases due to the increase in volume, so that the smoke liquid in the liquid storage chamber 1111 accelerates the flow rate through the liquid inlet 1134 due to the pressure difference. The electronic cigarette of the present invention can achieve oil and cotton separation when the user is not using the electronic cigarette, so as to facilitate the storage of smoke liquid; when the user is using the electronic cigarette, the speed of the smoke liquid in the liquid storage chamber 1111 passing through the liquid inlet 1134 is accelerated.

[0063] 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.
