[0053] The present invention will now be described in detail with reference to the accompanying drawings. This figure is a simplified schematic diagram, which only illustrates the basic structure of the present invention in a schematic manner, and therefore only shows the components related to the present invention.

[0054] Embodiment 1

[0055] See also Figure 1 , Figure 2, Embodiment 1 of the present invention provides an electronic cigarette 100, which includes a cartridge 101 and a power supply device 102 electrically connected to the cartridge 101, the cartridge 101 includes a liquid storage component 10, a connecting component 20 sleeved outside the liquid storage component 10, and an atomizing component 30 accommodated in the connecting component 20, wherein the power supply device 102 is connected to the connecting component 20, when in use, the smoke liquid stored in the liquid storage component 10 flows into the atomizing component 30, and the power supply device 102 supplies power to the atomizing component 30, so that the smoke liquid is heated by the atomizing component 30 to generate smoke, and the smoke is inhaled by the user. Among them, the connecting component 20, the atomizing component 30 and the power supply device 102 together constitute an atomizing device (not shown in the figure).

[0056] See also Figure 1 , 2 , 4, 5, in this embodiment, the connection assembly 20 of the atomization device for electronic cigarettes includes a connection sleeve 21 with a cavity therein and a cartridge connection seat 1023 connected to one end of the power supply device 102. The connection sleeve 21 and the cartridge connection seat 1023 are detachably connected, for example, by means of a snap connection or a threaded connection, etc. The upper end of the connection sleeve 21 and the upper end of the cartridge connection seat 1023 are arranged at an axial spacing along the longitudinal length of the power supply device 102, and the atomization assembly 30 is at least partially placed in the space between the upper end of the connection sleeve 21 and the upper end of the cartridge connection seat 1023. The upper end, lower end, etc. mentioned here refer to the reference direction when the electronic cigarette is in normal use, such as when it is placed on a desktop or held by a user, rather than an absolute definition.

[0057] See also Figure 3 , Figure 4 The liquid storage assembly 10 includes a liquid storage tube 11 and an end cover 12 arranged at the lower end of the liquid storage tube 11.

[0058] The liquid storage tube 11 is roughly in a convex shape, and an annular cavity is formed on the lower end surface of the liquid storage tube 11, which is recessed upward along the axial direction of the liquid storage tube 11. The annular cavity constitutes a liquid storage chamber 110 for storing smoke liquid. The upper end of the liquid storage chamber 110 is closed, and the lower end of the liquid storage chamber 110 is open. An air inlet channel 111 and an air outlet channel 112 are also provided in the liquid storage tube 11 along the axial direction of the liquid storage tube 11. The air inlet channel 111 and the air outlet channel 112 are both spaced apart from the liquid storage chamber 110. An air inlet hole 113 is provided on the side wall of the liquid storage tube 11 along the radial direction of the liquid storage tube 11. An air outlet hole 114 is provided on the upper end surface of the liquid storage tube 11. The air inlet hole 113 is connected to the outside atmosphere and the upper end of the air inlet channel 111. The lower end of the air inlet channel 111 passes through the lower end surface of the liquid storage tube 11. The lower end of the air outlet channel 112 passes through the lower end surface of the liquid storage tube 11. The upper end of the air outlet channel 112 is connected to the air outlet hole 114. When the user inhales, the external air enters through the air inlet hole 113, and then passes through the air inlet channel 111 and the air outlet channel 112 in sequence, and finally brings the generated smoke into the user's mouth through the air outlet hole 114.

[0059] It can be understood that during the user's inhalation process, the hot air flow in the air outlet channel 112 can preheat the smoke liquid in the liquid storage chamber 110, so that the smoke liquid has a higher temperature before entering the atomization component 30, which can accelerate the atomization efficiency of the smoke liquid and reduce energy consumption.

[0060] The end cap 12 is generally a circular plate-shaped structure, and the end cap 12 is sealed and installed at the lower end of the liquid storage chamber 110. In this embodiment, the lower end surface of the end cap 12 extends downward along the axial direction of the end cap 12 to form two oppositely arranged connecting pipes 121, and both ends of the connecting pipe 121 are connected and communicated with the liquid storage chamber 110.

[0061] The connecting assembly 20 includes a connecting sleeve 21 and a connecting piece 22 installed in the lower end of the connecting sleeve 21. The connecting sleeve 21 is generally a hollow cylindrical structure with two ends through, and the connecting sleeve 21 is sleeved on the outside of the lower end of the liquid storage tube 11. When installing the liquid storage assembly 10, it is only necessary to insert the lower end of the liquid storage tube 11 into the connecting sleeve 21. In addition, a snap-fit ​​protrusion (not shown in the figure) is provided on one of the inner wall of the connecting sleeve 21 and the outer wall of the liquid storage tube 11, and a snap-fit ​​groove (not shown in the figure) that cooperates with the snap-fit ​​protrusion is provided on the other. Through the snap-fit ​​relationship between the snap-fit ​​protrusion and the snap-fit ​​groove, the connection stability between the connecting assembly 20 and the liquid storage assembly 10 is further improved.

[0062] In addition, the liquid storage tube 11 is made of a transparent or translucent material, so that the user can observe the remaining amount of smoke liquid in the liquid storage chamber 110 through the liquid storage tube 11, so that the user can replace the liquid storage tube 11 in time. A limiting portion (not shown) is convexly provided on the outer peripheral surface of the liquid storage tube 11, and the upper end of the connecting sleeve 21 cooperates with the limiting portion. When the connecting sleeve 11 is installed in place, the limiting portion abuts against the upper end of the connecting sleeve 21, thereby limiting the installation of the liquid storage tube 11. In this embodiment, the lower end of the limiting portion is set in a wave curve shape, so as to play a positioning role with the liquid storage tube 11, and prevent the liquid storage tube 11 and the connecting sleeve 21 from rotating with each other. The engaging protrusion is set at the lower end of the limiting portion, and the card groove is set on the inner wall of the connecting sleeve 21.

[0063] The connector 22 is installed in the lower end of the connecting sleeve 21 by interference fit, and is abutted against the end cover 12. The connector 22 is generally in a plate-like structure, and the lower end of the connector 22 is threadedly matched with the upper end of the power supply device 102, thereby realizing a fixed connection relationship between the connecting assembly 20 and the power supply device 102. It can be understood that in other embodiments not shown, the connector 22 and the power supply device 102 can also be connected in a detachable manner such as a snap connection, a plug connection or a magnetic connection, which is not limited here.

[0064] Please refer again Figure 4 The lower end surface of the connecting member 22 is recessed upward to form a receiving groove 220, and the atomizing assembly 30 is received in the receiving groove 220. Please refer to Figure 5 The upper end surface of the connecting member 22 is provided with two through holes 221 arranged opposite to each other corresponding to the connecting tube 121. The through holes 221 constitute a liquid outlet through hole connected to the liquid storage chamber 110. The lower end of the connecting tube 121 passes through the through holes 221 and abuts against the atomizing assembly 30, so that the smoke liquid in the liquid storage chamber 110 can flow into the atomizing assembly 30 through the connecting tube 121, and is heated to generate smoke. In order to prevent the smoke liquid from leaking, a sealing ring 222 is sandwiched between the hole wall of the through hole 221 and the outer wall of the connecting tube 121. It can be understood that the material of the sealing ring 222 includes but is not limited to silicone or rubber.

[0065] Also, please refer again to Figure 4The connecting member 22 is provided with a U-shaped connecting channel 223, one end of which is connected to the air inlet channel 111, the other end of which is connected to the air outlet channel 112, and the lower end of which is connected to the receiving groove 220. The part of the connecting member 22 surrounded by the connecting channel 223 blocks part of the air inlet channel 111 and part of the air outlet channel 112, thereby blocking the fine smoke liquid particles splashed when frying oil, avoiding scalding the user and improving the safety of use. In order to facilitate the air flow through the end cover 12, the end cover 12 is provided with a first through hole 122 and a second through hole 123, wherein the first through hole 122 is connected to one end of the connecting channel 223 and the air inlet channel 111, and the second through hole 123 is connected to the other end of the connecting channel 223 and the air outlet channel 112. Figure 4 The direction indicated by the dashed arrow is the airflow direction.

[0066] See also Figure 3 , Figure 4 The atomizing assembly 30 includes an atomizing base 31 , a liquid absorbing element 32 received in the atomizing base 31 , and a heating element 33 mounted on the atomizing base 31 .

[0067] The atomizer base 31 is roughly a circular plate-shaped structure. The upper end surface of the atomizer base 31 is recessed downward to form a mounting groove 310. The liquid absorption element 32 is accommodated in the mounting groove 310. The heating element 33 is corresponding to the liquid absorption element 32 and is covered on the mounting groove 310 of the atomizer base 31, and the liquid absorption element 32 is pressed and fixed in the mounting groove 310. Mounting holes 311 are provided on the atomizing base 31 on opposite sides of the mounting groove 310. Two pins 331 are connected to the two ends of the heating element 33, one of which corresponds to one mounting hole 311. The two pins 331 are bent in opposite directions after passing through the corresponding mounting holes 311, and fit with the atomizing base 31. At this time, due to the bending effect of the pins 331, the heating element 33 is not easy to be pulled out, so that the heating element 33 is fixed on the atomizing base 31, which can effectively prevent the heating element 33 from loosening, and the operation is simple and convenient to use. At the same time, it is ensured that the liquid absorption element 32 and the heating element 33 can be fully in contact, thereby improving the atomization efficiency of the smoke liquid. It can be understood that in other embodiments not shown, there can be only one mounting hole 311, and correspondingly, there is only one pin 331. At this time, one pin 331 of the heating element 33 passes through the mounting hole 311 and is bent, which can also play a fixing role on the heating element 33.

[0068] In one of the embodiments not shown, the lower end of the connecting tube 121 is pre-sealed with a seal (not shown). That is, before the liquid storage assembly 10 is installed with the atomizer assembly 30, the smoke liquid in the liquid storage assembly 10 is isolated from the outside world. The seal can be aluminum foil or other similar metal films, or a plastic film, etc. After the liquid storage assembly 10 is installed on the atomizer assembly 30, a piercing member (not shown) arranged on the atomizer base 31 pierces the seal, so that the sealing effect is destroyed, and the smoke liquid in the liquid storage assembly 10 is introduced into the atomizer assembly 30, so that the smoke liquid is continuously heated and atomized after the atomizer assembly 30 is powered on. After the smoke liquid in the liquid storage assembly 10 is used up, the liquid storage assembly 10 can be directly removed from the atomizer assembly 30 without being discarded as a whole, thereby reducing the user's use cost.

[0069] It is understandable that in other embodiments not shown, the piercing member is installed in the liquid outlet through hole. When the liquid storage component 10 and the connecting component 20 are installed in place, the connecting tube 121 acts as the piercing member to pierce the sealing member, thereby allowing the smoke liquid to flow out of the liquid storage chamber 110.

[0070] When the user uses it, the power supply device 102 supplies power to the heating element 33, and the heating element 33 generates heat to heat the smoke liquid absorbed by the liquid absorbing element 32, thereby generating smoke from the smoke liquid. In addition, at least one smoke-permeable hole (not shown) is provided on the heating element 33, and the smoke-permeable hole is a through hole and is connected to the connecting channel 223, so that smoke can flow into the user's mouth through the smoke-permeable hole. When the user needs to replace the heating element 33 and the liquid absorbing element 32, he only needs to straighten the pin 331, then pull out the heating element 33, and further remove the liquid absorbing element 32 from the mounting groove 310.

[0071] Specifically, the lower end of the connecting tube 121 passes through the through hole 221 of the connecting member 22 and abuts against the liquid absorbing element 32, thereby ensuring that the smoke liquid can be absorbed by the liquid absorbing element 32 in time, increasing the speed of absorbing the smoke liquid and avoiding the leakage of the smoke liquid. Figure 5 The direction indicated by the solid arrow is the direction of smoke liquid flow.

[0072] The liquid absorbing element 32 has the function of absorbing smoke liquid. It can be understood that the liquid absorbing element 32 is a porous liquid absorbing member. The liquid absorbing element 32 can be one, two or more of cotton, porous ceramics, fiber rope, foam metal, and foam graphite. In this embodiment, the liquid absorbing element 32 is cotton. The heating element 33 is a sheet structure. The heating element 33 is a heating element that can generate heat when powered. In this embodiment, the heating element 33 is a metal heating sheet, and the heating element 33 and the pin 331 are an integrally formed structure.

[0073] In this embodiment, the material of the atomizer base 31 is liquid-absorbing ceramic, which has the ability to absorb liquid, can absorb and store part of the smoke liquid, and can effectively prevent dry burning. At this time, the atomizer base 31 not only has the function of installing the liquid-absorbing element 32, but also plays the role of absorbing liquid. It can be understood that when the atomizer base 31 is liquid-absorbing ceramic, since the pin 331 fits with the atomizer base 31, the pin 331 can heat the smoke liquid on the liquid-absorbing ceramic, further improving the atomization efficiency.

[0074] Please refer again Figure 4 The power supply device 102 includes a housing 1021, a battery 1022 accommodated in the housing 1021, a cartridge connection seat 1023 installed at one end of the housing 1021, and a first electrode 1024 installed on the cartridge connection seat 1023, wherein the cartridge connection seat 1023 is detachably connected to the connector 22, the first electrode 1024 is electrically connected to one of the positive and negative electrodes of the battery 1022, and the cartridge connection seat 1023 is electrically connected to the other of the positive and negative electrodes of the battery 1022. Specifically, the connector 22 is detachably connected to the cartridge connection seat 1023. In this embodiment, the connector 22 is threadedly connected to the cartridge connection seat 1023. It can be understood that in other embodiments not shown, the connector 22 and the cartridge connection seat 1023 can also be detachably connected by means of snap-on, plug-in or magnetic connection, which is not limited here. When the connecting assembly 20, the atomizing assembly 30 and the power supply device 102 are installed in place, the atomizing assembly 30 is at least partially placed in the space between the lower end of the connecting member 22 and the upper end of the cartridge connecting seat 1023, and one pin 331 of the heating element 33 is in contact with and electrically connected to the first electrode 1024, and another pin 331 of the heating element 33 is in contact with and electrically connected to the cartridge connecting seat 1023, thereby realizing the electrical connection relationship between the heating element 33 and the power supply device 102. In addition, an insulating member (not shown in the figure) is sandwiched between the first electrode 1024 and the cartridge connecting seat 1023, and the insulating member plays an electrical isolation role to avoid short circuit. It can be understood that the material of the insulating member is an insulating material such as rubber or silicone.

[0075] In the electronic cigarette 100 provided in the first embodiment of the present invention, when the atomizer assembly 30 needs to be replaced, the connection between the connection assembly 20 and the power supply device 102 can be released to remove the atomizer assembly 30. Moreover, the liquid absorption element 32 and the heating element 33 on the atomizer assembly 30 are convenient to be disassembled and replaced separately, which reduces material waste and saves costs. In addition, when the smoke liquid in the liquid storage assembly 10 is used up, the user can drip smoke liquid on the liquid absorption element 32 after pulling out the liquid storage assembly 10, so that the electronic cigarette 100 can be continued to be used, and the functions of liquid storage electronic cigarette and liquid dripping electronic cigarette can be realized respectively, which improves the user's experience.

[0079] See also Fig. 9 , Fig.10The liquid storage tube 11 is roughly cylindrical in structure. The center of the lower end surface of the liquid storage tube 11 is recessed upward along the axial direction of the liquid storage tube 11 to form a liquid storage cavity 110 for storing smoke liquid. The upper end of the liquid storage cavity 110 is closed, and the lower end of the liquid storage cavity 110 is open. An air inlet channel 111 and an air outlet channel 112 are provided in the liquid storage tube 11 along the axial direction of the liquid storage tube 11. The air inlet channel 111 and the air outlet channel 112 are both spaced apart from the liquid storage chamber 110. An air inlet hole 113 is provided on the side wall of the liquid storage tube 11 along the radial direction of the liquid storage tube 11. An air outlet hole 114 is provided on the upper end surface of the liquid storage tube 11. The air inlet hole 113 is connected to the outside atmosphere and the upper end of the air inlet channel 111. The lower end of the air inlet channel 111 passes through the lower end surface of the liquid storage tube 11. The lower end of the air outlet channel 112 passes through the lower end surface of the liquid storage tube 11. The upper end of the air outlet channel 112 is connected to the air outlet hole 114. When the user inhales, the external air enters through the air inlet hole 113, and then passes through the air inlet channel 111 and the air outlet channel 112 in sequence, and finally brings the generated smoke into the user's mouth through the air outlet hole 114.

[0080] It can be understood that during the user's inhalation process, the hot air flow in the air outlet channel 112 can preheat the smoke liquid in the liquid storage chamber 110, so that the smoke liquid has a higher temperature before entering the atomization component 30, which can accelerate the atomization efficiency of the smoke liquid and reduce energy consumption.

[0081] The tail cap 13 is roughly in the shape of a circular plate. The tail cap 13 is provided with a liquid outlet hole 131 communicating with the liquid storage chamber 110, an air inlet hole 132 communicating with the air inlet channel 111, and an air outlet hole 133 communicating with the air outlet channel 112. A sealing member (not shown) is installed in the liquid outlet hole 131. The sealing member is arranged along the radial direction of the liquid outlet hole 131 and can close the lower end opening of the liquid storage chamber 110. When the sealing member is pierced by an external force, the smoke liquid in the liquid storage chamber 110 can flow out through the liquid outlet hole 131.

[0082] In this embodiment, the connection assembly 20 includes a connection sleeve 21 and a connection member 22 and an end cover 23 both received in the connection sleeve 21 , wherein the end cover 23 is connected to the connection member 22 and is located above the connection member 22 .

[0083] The connecting sleeve 21 is generally a hollow cylindrical structure with two ends through, and the connecting sleeve 21 is sleeved on the outside of the lower end of the liquid storage tube 11. When installing the liquid storage assembly 10, it is only necessary to insert the lower end of the liquid storage tube 11 into the connecting sleeve 21. In addition, a snap-fit ​​protrusion (not shown in the figure) is provided on one of the inner wall of the connecting sleeve 11 and the outer wall of the liquid storage tube 11, and a snap-fit ​​groove (not shown in the figure) that cooperates with the snap-fit ​​protrusion is provided on the other. Through the snap-fit ​​relationship between the snap-fit ​​protrusion and the snap-fit ​​groove, the connection stability between the connecting assembly 20 and the liquid storage assembly 10 is further improved.

[0084] See also Fig. 9 The end cover 23 is installed in the lower end of the connecting sleeve 21 by interference fit. The end cover 23 is generally a circular plate-shaped structure. A connecting pipe 231 is inserted in the center of the end cover 23. Both ends of the connecting pipe 231 are connected and correspond to the liquid outlet through hole 131. In addition, a first through hole 122 and a second through hole 123 are opened on the end cover 23, wherein the first through hole 122 is connected to the air inlet through hole 132, and the second through hole 123 is connected to the air outlet through hole 133.

[0085] The connector 22 is generally a cylindrical structure with two ends through, and the cavity of the connector 22 forms a receiving groove 220, and the atomizer assembly 30 is received in the receiving groove 220. The lower end of the end cover 23 is inserted into the connector 22, and the connecting pipe 231 is abutted against the atomizer assembly 30, so that the smoke liquid in the liquid storage chamber 110 can flow into the atomizer assembly 30 through the connecting pipe 231, and is heated to generate smoke. In order to improve the connection stability between the connector 22 and the end cover 23, the connector 22 and the end cover 23 are clamped.

[0086] In addition, the lower end of the connector 22 is engaged with the upper end of the power supply device 102, thereby achieving a fixed connection between the connector assembly 20 and the power supply device 102. It can be understood that in other embodiments not shown, the connector 22 and the power supply device 102 can also be connected in a detachable manner such as a threaded connection, a plug-in connection, or a magnetic connection, which is not limited here.

[0087] See also Figure 7 , the connecting sleeve 21 is provided with a notch 211, and the notch 211 extends from the upper end of the connecting sleeve 21 to the lower end of the connecting sleeve 21. When the liquid storage component 10 is installed on the connecting component 20, the smoke liquid in the liquid storage component 10 can be observed through the notch 211. For example, a window 115 is provided on the liquid storage component 10, and only the window 115 on the liquid storage component 10 is made of a transparent or translucent material, while the other parts are not transparent, such as black or other dark colors. When the liquid storage component 10 is installed on the connecting component 20, due to the existence of the notch 211, the window 115 on the liquid storage component 10 is adapted to the notch 211, and the smoke liquid in the liquid storage component 10 can be observed from the outside through the notch 211 and the window 115, and it is determined whether the liquid storage component 10 needs to be discarded and replaced with a new liquid storage component 10.

[0088] When the liquid storage component 10 is connected to the connecting component 20, the connecting tube 231 is inserted into the liquid outlet through hole 131 and pierces the sealing member. At this time, the smoke liquid in the liquid storage chamber 110 flows into the atomizer component 30 through the liquid outlet through hole 131. In this embodiment, the sealing member is a plastic film, which cannot be repaired after being punctured. When the smoke liquid is used up, a new liquid storage component 10 can be replaced. It can be understood that in other embodiments not shown, the sealing member is rubber, and a groove is provided on the sealing member. In the natural state, the groove is automatically closed to seal the liquid storage chamber 110, and when the connecting tube 231 passes through the groove, the groove is pushed open, thereby opening the liquid storage chamber 110. Therefore, after the smoke liquid is not used up, the user can remove the liquid storage component 10 at any time to prevent the smoke liquid from continuously contacting the atomizer component 30, thereby damaging the atomizer component 30. It can be understood that the connecting tube 231 in this embodiment is used as the piercing member to pierce the sealing member to allow the smoke liquid in the liquid storage chamber 110 to flow out. In addition, in order to prevent the smoke liquid from leaking between the tail cap 13 and the end cover 23, a sealing ring 222 is sandwiched between the hole wall of the liquid outlet through hole 131 and the outer wall of the connecting tube 231. The material of the sealing ring 222 includes but is not limited to silicone or rubber.

[0089] The atomizer assembly 30 includes an atomizer base 31, a liquid absorption element 32 accommodated in the atomizer base 31, and a heating element 33 installed on the atomizer base 31, wherein the structures and connection relationships of the atomizer base 31, the liquid absorption element 32 and the heating element 33 are the same as those in Example 1 and are not repeated here. The main difference is that, in this embodiment, the atomizer assembly 30 is detachably connected to the power supply device 102.

[0090] Please refer again Fig. 9The power supply device 102 includes a housing 1021, a battery 1022 accommodated in the housing 1021, a cartridge connection seat 1023 installed at one end of the housing 1021, and a first electrode 1024 and a second electrode 1025 installed on the cartridge connection seat 1023, wherein the connector 22 is clamped on the outside of the cartridge connection seat 1023, and the atomization base 31 of the atomization assembly 30 is clamped on the inside of the cartridge connection seat 1023. The first electrode 1024 is electrically connected to one of the positive and negative electrodes of the battery 1022, and the second electrode 1025 is electrically connected to the other of the positive and negative electrodes of the battery 1022. When the connection assembly 20, the atomization assembly 30 and the power supply device 102 are installed in place, one pin of the heating element 33 contacts and is electrically connected to the first electrode 1024, and another pin 331 of the heating element 33 contacts and is electrically connected to the second electrode 1025, thereby realizing the electrical connection relationship between the heating element 33 and the power supply device 102. In addition, an insulating member (not shown) is sandwiched between the first electrode 1024 and the second electrode 1025 and the cigarette cartridge connection seat 1023, and the insulating member plays an electrical isolation role to avoid short circuit. It can be understood that the insulating member is made of insulating materials such as rubber or silicone.

[0091] Also, please refer again to Figure 8 , Fig. 9 A sealing gasket 24 is sandwiched between the end cap 23 and the atomizing base 31. The sealing gasket 24 has a through groove (not shown) corresponding to the liquid absorbing element 32. The through groove is connected to both the first through hole 122 and the second through hole 123. The connecting pipe 231 passes through the through groove and abuts against the liquid absorbing element 32 to achieve liquid communication between the liquid storage chamber 110 and the liquid absorbing element 32. By providing the sealing gasket 24, gas leakage can be prevented. The material of the sealing gasket 24 includes but is not limited to silicone or rubber.

[0092] When the user uses it, the smoke liquid in the liquid storage chamber 110 is absorbed by the liquid absorption element 32 through the connecting tube 231, and smoke is generated under the heating of the heating element 33. The external air enters through the air inlet hole 113, passes through the air inlet channel 111, the air inlet through hole 132 and the first through hole 122 in sequence, and then flows through the upper end surface of the liquid absorption element 32, and then passes through the second through hole 123, the air outlet through hole 133 and the air outlet channel 112 in sequence, and then enters the user's mouth through the air outlet hole 114. Fig. 9 The direction indicated by the dashed arrow is the airflow direction. Fig. 9 The direction indicated by the solid arrow is the direction of smoke liquid flow.

[0093] In the electronic cigarette 200 provided in the second embodiment of the present invention, when the atomizer assembly 30 needs to be replaced, the connection between the connection assembly 20 and the power supply device 102 can be released to remove the atomizer assembly 30. Moreover, the liquid absorption element 32 and the heating element 33 on the atomizer assembly 30 are convenient to be disassembled and replaced separately, which reduces material waste and saves costs. In addition, when the smoke liquid in the liquid storage assembly 10 is used up, the user can drip smoke liquid on the liquid absorption element 32 after pulling out the liquid storage assembly 10, so that the electronic cigarette 200 can continue to be used, and the functions of liquid storage electronic cigarette and liquid dripping electronic cigarette can be realized respectively, which improves the user's experience.

[0094] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the scope of the present invention through the above description. The technical scope of this invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
